RELEASE-NOTES revision 73c427d2a3f28c34280e51db76e580d9730c0cbf
1E2fsprogs 1.42.7 (January 1, 2013)
2==================================
3
4Add some new options to filefrag from Lustre's patches to e2fsprogs:
5    * add -k option to print extents in kB-sized units (like df -k)
6    * add -b {blocksize} to print extents in blocksize units
7    * add -e option to print extent format, even when FIBMAP is used
8    * add -X option to print extents in hexadecimal format
9
10Fix resize2fs so that it can handle off-line resizes of file systems
11with the flex_bg feature but without a resize_inode (or if we run out
12of reserved gdt blocks).  This also fixes a problem where if the user
13creates a filesystem with a restricted number of reserved gdt blocks,
14an off-line resize which grows the file system could potentially
15result in file system corruption.
16
17Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
18mke2fs crash due to a divide-by-zero if the 64bit file system feature
19is enabled.
20
21Add to debugfs the functionality to corrupt a specific file system
22block via the "zap_block" command.
23
24Add to debugfs the functionality to print out a hex dump of a block in
25the file system via the "block_dump" command.
26
27Add to debugfs the functionality to manipulate the extent tree
28directly via the "extent_open" command.
29
30Fix e2fsck so it can detect and fix inconsistencies in the interior
31nodes of an inode's extent tree.
32
33Fix mke2fs's handling of the mmp_update_interval option.  (Addresses
34Lustre Bug: LU-1888)
35
36If e2fsprogs is compiled without --enable-quota, make sure that
37tune2fs can not turn on the feature for new-style quota support, since
38afterwards, none of the e2fsprogs tools will be willing to touch that
39file system.
40
41Optimize e2fsck's so that it uses much less CPU for large file
42systems.  This can result in significant speedups, especially on
43CPU-constrained systems.  This was primarily done by optimizing
44libext2fs's bitmap functions.  (Addresses Google Bug: #7534813)
45
46Fix debugfs's htree command so that all its messages are sent through
47the pager.
48
49Fixed debugfs's "dump_file" and "cat" functions work correctly
50on file systems whose block size is greater than 8k.
51
52Fix e2freefrag so it works on 64-bit file systems, and so it uses much
53less memory.  (Addresses Google Bug: 7269948)
54
55
56Programmer's Notes
57------------------
58
59Fix gcc -Wall nits.
60
61Fix a spelling typo in the libext2fs texinfo documentation.
62
63Change the output from "make check" so that tools such as emacs's "M-x
64compile" does not mistake the output as containing a compiler error.
65
66Export two new functions from libext2fs: ext2fs_extent_node_split()
67and ext2fs_extent_goto2().
68
69The ext2fs_extents_fix_parents() was fixed so it does not modify the
70location of the extent handle if its current location is at an
71interior node, rather than a leaf node of an inode's extent tree.
72
73Add a regression test to assure that e2fsck can correctl fix an
74inconsistent interior node in an inode's extent tree.
75
76Fixed the help text in the configure script for --enable-quota.
77
78The m68k-specific bitops code has been removed since they were
79incorrectly treating bit numbers with the high bit set as signed
80integers.  Furthermore, modern compilers do a good enough job
81optimizing the generic code there is no point in having the m68k
82specific asm statements.
83
84Fixed how we link the test programs so they always use the static
85libraries, so that we test using the libraries which we have just
86built.
87
88
89E2fsprogs 1.42.6 (September 21, 2012)
90=====================================
91
92When mke2fs creates file systems with lazy itable initialization, the
93progress updates for writing the inode table happens so quickly that
94on a serial console, the time to write the progress updates can be the
95bottleneck.  So mke2fs will now only update its progress indicators
96once a second.
97
98Resize2fs will skip initializing the inode tables if the kernel
99supports lazy_itable_init, which speeds up growing off-line growth of
100uninit_bg file systems significantly.  Resize2fs will now also
101correctly set the itable_unused field in the block group descriptor to
102speed up the first e2fsck after the file system is grown.
103
104Resize2fs has been fixed so that on-line resizing of meta_bg file
105systems work correctly.  This is needed to grow file system which are
106larger than 16T.
107
108Resize2fs will now correctly handle resizing file systems to 16TB on
10932-bit file systems when "16TB" is specified on the command line.
110
111Fix mke2fs so that it will be careful to set the reserved blocks ratio
112larger than 50%; this can happen when creating small file systems and
113when the last block group is dropped because there are not enough
114blocks to support the metadata blocks in the last block group.
115
116Fixed spelling mistake in debugfs's help message.
117
118Fixed a potential seg fault in e2fsck when there is an I/O error while
119reading the superblock.
120
121Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
122
123Updated/fixed various man pages.  (Addresses Sourceforge Bug:
124#3559210)
125
126Programmer's Notes
127------------------
128
129The configure option --enable-relative-symlink was broken so that it
130needed to be --enable-symlink-relative-symlinks.  We will support both
131for at least two years, but then the worng configure option will be
132removed.
133
134Fixed a regression introduced in 1.42.5 so the link order for
135e2fsprogs' libraries will be correct for both static and shared
136linking.  (Addresses Sourceforge Bug: #3554345)
137
138Add support for e2fsprogs to be compiled using clang/LLVM.
139
140Fix portability problems on non-Linux systems: avoid compile failures
141on systems that don't have malloc.h
142
143Fix f_mmp regression test suite so that debugfs gets killed if the
144test is interrupted.
145
146
147
148E2fsprogs 1.42.5 (July 29, 2012)
149================================
150
151Fixed a bug with mke2fs where if there is only 8 inodes per block
152group, the calculation of the number of uninitialized inodes in the
153first block group would go negative.  This resulted in "mke2fs -N 256
154-t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
155would run out of space.  (Addresses Sourceforge Bug: #3528892)
156
157Fixed a bug in how e2fsck would uniquify directory entry names.
158(AddressesSourceforge Bug: #3540545)
159
160Previously, e2fsck would only allow a mounted file system to be
161checked if it was the root file system and it was mounted read-only.
162Now it will allow any file system mounted read-only to be checked if
163the -f option is specified.  This makes it easier to test how e2fsck
164handles checking file systems which are mounted without having to test
165on the root file system.
166
167Fixed a problem if e2fsck where if the root file system is mounted
168read-only, e2fsck would not clear an error indication in the journal
169superblock.  Combined with a kernel bug, this would cause the e2fsck
170to check the file system after every single boot.
171
172The e4defrag program can now handle device symlinks, such as
173/dev/mapper/testvg-testlv, instead of insisting on a less
174human-friendly name such as /dev/dm-2.  (Addresses Red Hat Bugzilla:
175#707209)
176
177Fixed filefrag so it will not crash with a segfault on files from a
178virtual file system such as /proc.  (e.g., "filefrag
179/proc/partitions")
180
181Fixed filefrag so that it correctly reports the number of extents.
182(Addresses Red Hat Bugzilla: #840848)
183
184Fixed a file descriptor leak in logsave which could cause it to hang.
185(Addresses Debian Bug: #682592)
186
187Fixed e2fsck so that the file system is marked as containing an error
188if the user chooses not to fix the quota usage information.
189
190Fixed tune2fs so that it correctly removes the quota feature when the
191last quota inode is removed.
192
193Fix tune2fs so that after removing a quota inode, the block bitmap is
194updated; otherwise, e2fsck would complain after running 'tune2fs -O
195^quota <dev>'.
196
197Fix tune2fs so that when converting a file system from using legacy
198quota files to the new quota file system feature with hidden quota
199files, the accounting for these files is handled correctly so that
200e2fsck doesn't complain.
201
202Improved e2fsck's verbose reporting statistics, and allow the more
203verbose reporting to be enabled via /etc/e2fsck.conf.
204
205Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
206
207Updated/fixed various man pages.  (Addresses Debian Bugs: #680114)
208
209
210Programmer's Notes
211------------------
212
213Fixed portability problems on other operating systems (e.g., Hurd and
214FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
215
216Make sure that shared libraries link with the shared libraries built
217in the build tree, instead of the system provided libraries.
218Previously, libraries and executables were linked with the system
219libraries if present, and possibly using static archives instead of
220shared libraries.  This was also problematic since if libext2fs.so is
221linked with a static libcom_err.a from system, the build system would
222attempt to link without -lpthread.  (Addresses Sourceforge Bug:
223#3542572)
224
225
226E2fsprogs 1.42.4 (June 12, 2012)
227================================
228
229Fixed more 64-bit block number bugs (which could end up corrupting
230file systems!) in e2fsck, debugfs, and libext2fs.
231
232Fixed e2fsck's handling of the journal's s_errno field.  E2fsck was
233not properly propagating the journal's s_errno field to the superblock
234field; it was not checking this field if the journal had already been
235replayed, and if the journal *was* being replayed, the "error bit"
236wasn't getting flushed out to disk.
237
238Fixed a false positive complaint by e2fsck if all of the extents in
239the last extent tree block are uninitalized and located after the end
240of the file as defined by i_size.
241
242The dumpe2fs will now display the journal's s_errno field if it is
243non-zero, and it will also display the journal's 64-bit feature flag
244if present.
245
246Fix e2fsck so that it always opens the device file in exclusive mode
247when it might need to modify the file system, and never if the -n
248option is specified.  (Previously, there were a few corner cases where
249it might get things wrong in either direction.)
250
251E2fsck now correctly truncates or deallocates extent-mapped inodes on
252the orphan list.  The root cause was a bug in libext2fs's block
253iterator which could end up skipping an extent when the last block in
254an extent is removed, causing the current extent to be removed from
255the extent tree.
256
257E2fsck now correctly sets the global free block and inode counts when
258truncating or removing inodes on the orphan list in preen mode.
259Previously, it would leave these values would be set incorrectly,
260which is largely a cosmetic issue since the kernel no longer pays
261attention to those fields, but it can cause spurious complaints in
262subsequent e2fsck runs.
263
264Fix i_blocks accounting when the libext2fs library needs to add or
265remove an extent tree block  on bigalloc file systems.
266
267The lsattr and chattr programs now support the No_COW flag for the
268benefit of btrfs.
269
270Debugfs now interprets date strings of the form @ddd as ddd seconds
271after the beginning of the epoch.  This is handy when setting an inode
272number into the d_time field when debugging orphan list handling.
273
274Fix a precedence bug with built-in quota support which might result in
275e2fsck paying attention to the quota inode field even if the built-in
276quota feature flag is not set.  Fortunately, in practice that
277superblock field should be zero for non-built-in quota file systems,
278so it's unlikely this bug would have caused problems.
279
280Updated/fixed various man pages.  (Addresses Debian Bugs: #674453,
281#674694)
282
283Programmer's Notes
284------------------
285
286The regression test suite can now run the integration tests in the
287tests directory in parallel, via "make -jN check".
288
289Add new test, f_zero_extent_length which tests e2fsck's handling of
290the case where all of the extents in the last extent tree block are
291uninitialized extents after i_size.
292
293Add a new test, f_jnl_errno, which checks handling of an error
294indication set in the journal superblock.
295
296Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
297of a 64-bit journal.
298
299Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
300tests e2fsck's handling of orphan inodes in preen mode, and truncation
301of extent inodes on the orphan list.
302
303Fixed more OS X portability issues.
304
305
306E2fsprogs 1.42.3 (May 14, 2012)
307===============================
308
309Fix a bug in the Unix I/O manager which could cause corruption of file
310systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
311(i.e., when unsigned long is 32-bits).  Also fix a bug which caused
312dumpe2fs to incorrectly display block numbers > 32-bits.
313
314Improve the support for integrated quota files (where quota is a first
315class supported feature using hidden files in the ext4 file system).
316Previously the quota file was getting rewritten even when it was not
317necessary, and e2fsck would erroneously try to hide quota files which
318were already hidden.
319
320Quiet complaints in e2fsck when the total free blocks or inodes are
321incorrect in the superblock after an system crash, since we don't
322update nor depend on the superblock summaries at each commit boundary.
323
324Fixed a regression introduced in 1.42.2 which would cause applications
325outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
326would were still using the legacy 32-bit bitmaps) to crash.  This was
327due to missing 32-bit compat code in side the function
328ext2fs_find_first_zero_generic_bmap().  (Addresses Red Hat Bugzilla:
329#808421)
330    
331Fix a bug which would cause mke2fs to fail creating the journal if
332/etc/mtab and /proc/mounts are missing.  (Addresses Sourceforge Bug:
333#3509398)
334    
335Updated/fixed various man pages.
336
337Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
338translations
339
340Fixed various Debian Packaging issues.
341
342
343Programmer's Notes
344------------------
345
346Change the nonsensically wrong types in the function signature of the
347inline function ext2fs_find_first_zero_block_bitmap2().  This was
348caused by a cut and paste error; fortunately no code in e2fsprogs used
349this inline function, and there are any users of this functions
350outside of e2fsprogs.
351
352Add support for systems which have valloc(), but which do have
353posix_memalign() nor memalign() (such as MacOS 10.5).
354
355Refactor and clean up the allocation of aligned buffers for Direct I/O
356support.  Previously some allocations were requesting a greater
357alignment factor that what was strictly necessary.  Also optimize
358reading and writing bitmaps using Direct I/O when the size of the
359bitmap did not fully cover the file system blocksize.
360
361Reserve the codepoints for the INCOMPAT features LARGEDATA and
362INLINEDATA.
363
364Improved the regression test suite by adding some new integration
365tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
366jbd2 format, as well as f_eofblocks which tests the new handling of
367uninitialized and initialized blocks beyond i_size.  Also add a new
368unit test which verifies 32-bit bitmaps support and the new
369find_first_zero primitives.
370
371Add a few dependencies to fix parallel (make -j) builds.
372
373Removed bash'isms which were breaking the regression test suite on
374systems where /bin/sh is not bash.
375
376The config.guess and config.sub have been updated to the 2012-02-10
377version.
378    
379Fix a portability problem caused by assuming the present of mntent.h
380means that setmntent() exists.  Instead, explicitly test for this in
381the configure script.
382
383If the sys/signal.h header file does not exist, don't try to include
384it, since it's not available on all systems.
385
386Add support for systems that do not support getpwuid_r()
387    
388The configure script now supports a new option,
389--enable-relative-symlinks, which will install relative symlinks for
390the ELF shared library files.  (Addresses Sourceforge Bug: #3520767).
391    
392When building BSD shared libraries make sure the LDFLAGS variable is
393passed to the linker.  Fixing this allows, for example, e2fsprogs to
394be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
395#3517272)
396    
397Fix gcc -Wall nitpicks
398
399
400E2fsprogs 1.42.2 (March 27, 2012)
401=================================
402
403The resize2fs program uses much less CPU and is much faster for very
404large file systems.  (Addresses Debian Bug: #663237)
405
406The seti and freei commands in debugfs can now take an optional length
407argument to set and clear a contiguous range of inodes.
408
409E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
410plan to remove support for it from the kernel file system driver.  It
411really wasn't very useful and was causing more problems than it
412solves.  Since e2fsck will complain if inodes that should have
413EOFBLOCKS_FL do not have the flag set, we are going to remove this
414check from e2fsprogs first, and then only remove the flag from the
415kernel much later.
416
417The mke2fs program can now use direct I/O via "mke2fs -D".  This will
418slow down the mke2fs, but it makes it more polite on a loaded server
419by limiting the amount of memory that gets dirtied by mke2fs when it
420is using buffered I/O.
421
422E2fsck was needlessly closing and re-opening the file system as a side
423effect of adding Multiple Mount Protection (MMP).  This isn't
424necessary for non-MMP file systems, so drop it.
425
426Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
427can more easily diagnose memory allocation failures caused by
428insufficient memory.  E2fsck will now abort if there are memory
429allocation failures when the file system is initially opened and
430during the block group descriptor checks.  (Addresses Google Bug:
431#6208183)
432
433If there are incorrect block group checks, e2fsck will now report the
434incorrect and corrected checksum values.
435
436The e2fsck progam can now write log files containing the details of
437the problems that were found and fixed directly, via configuration
438parameters in /etc/e2fsck.conf.
439
440Added the ability to limit the number of messages reported by e2fsck
441for a given problem type.  This avoids a potential bottleneck if there
442is a serial console which can cause a boot sequence to take a long
443time if e2fsck needs to report many, many file system errors.
444
445The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
446them to use much less memory for large file systems.
447
448The dumpe2fs program will now print the expected block group checksum
449if it is incorrect.  This helps to diagnose problems caused by
450incorrect block group checksums.
451
452E2fsck now checks for extents with a zero length, since the kernel
453will oops if it comes accross such a corrupted data structure.  (See
454https://bugzilla.kernel.org/show_bug.cgi?id=42859)
455
456E2fsck has a number of bugs relating to discard that have been fixed.
457(1) Fixed a bug which could cause e2fsck to discard portions of the
458inode table which were actually in use.  (2) E2fsck will now avoid
459using discard if the block device doesn't zero data on discard, since
460otherwise this could cause problems if the file system gets corrupted
461in the future.  (3) E2fsck will now avoid using discard when it is run
462in read-only mode.  (4) Fixed a bug which caused e2fsck to not issue
463discards in the last block group.
464
465E2fsck's CPU utilization in pass 5 has been optimized, which will
466speed up e2fsck slightly.
467
468E2image will now skip copying uninitialized bitmap and inode table
469blocks.
470
471Fixed mke2fs -S so it does not corrupt the first block group's
472information.
473
474E2fsck will now check the new sysfs interface to determine if we are
475using the battery or AC mains.  (Addresses SourceForge Bug: #3439277)
476
477Updated/fixed various man pages.  (Addresses Debian Bug: #665427)
478
479Fixed various Debian Packaging issues.  (Addresses Debian Bug: #665885)

481Programmer's Notes
482------------------
483
484Fixed various portability issues for non-Linux systems, particularly
485MacOS X, as well as Linux systems running with the just-released glibc
4862.15.
487
488Fix file descriptor leak in ext2fs_close() if the file system with
489uninit_bg is opened read/only with a backup superblock.  (Addresses
490SourceForge Bug: #3444351)
491
492Fixed an invalid return in a non-void function in the quota code.
493(Addresses SourceForge Bug: #3468423)
494
495Fixed the debian rules file so that the calls to dpkg-buildflags works
496when the shell is dash.
497
498The debian package build now uses V=1 so that there is more
499information about potential build failures in debian buildd logs.
500
501If the uninit flags get cleared by functions such as
502ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
503superblock is marked dirty and the block group descriptor checksum is
504updated if necessary.
505
506The debian rules file will now try to load debian/rules.custom of it
507exists.  This flie can skip various builds for speed reasons if there
508is no need for the e2fsck-static or udeb packages.  Available
509customizations in the rules file includes SKIP_STATIC=yes,
510SKIP_BF=yes, and SKIP_DIETLIBC=yes.
511
512In addition, if the file misc/mke2fs.conf.custom.in exists in the
513source tree, it will be used instead of the standard misc.conf file in
514the upstream sources.  This makes it easier for Debian-derived systems
515to distribute a custom mke2fs.conf file without having to worry about
516merge issues if future versions of e2fsprogs makes changes in the
517upstream default version of mke2fs.conf.
518
519
520E2fsprogs 1.42.1 (February 17, 2012)
521===================================
522
523The mke2fs and e2fsck now use significantly less memory when creating
524or checking very large file systems.  This was enabled by adding
525extent-based bitmaps which are stored using a red-block tree, since
526block and inode allocations tend to be contiguous.
527
528The command mke2fs -S is used as a last ditch recovery command to
529write new superblock and block group descriptors, but _not_ to destroy
530the inode table in hopes of recovering from a badly corrupted file
531system.  So if the uninit_bg feature is enabled, mke2fs -S will now
532set the unused inodes count field to zero.  Otherwise, e2fsck -fy
533after using mke2fs -S would leave the file system completely empty.
534
535Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
536honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
537installed an mke2fs binary using that name.
538
539The usage and help messages for the -G, -t and -T options in mke2fs
540have been fixed.
541
542If e2fsck needs to use the backup group descriptors, the
543ext2fs_open2() function clears the UNINIT bits to ensure all of the
544inodes in the file systems get scanned.  However, the code which reset
545the UNINIT flags did not also recalculate the checksum, which produced
546many spurious (and scary) e2fsck messages.  This has been fixed by
547resetting cheksums when the UNINIT bits are cleared.
548
549Relax a check in e2fsck which required that the block bitmap to be
550initialized when the inode bitmap is in use.  This will allow us to
551eventually eliminate code from the kernel which forcibly initialized
552the block bitmap when the inode bitmap is first used, requiring an
553extra journal credit and disk write.  (Addresses Google Bug: #5944440)
554    
555Make sure rdebugfs (which may be installed setuid or setgid disk) does
556not honor environment variables if euid != uid or egid != gid.
557
558Debugfs's ncheck command has been optimized and now is much more
559robust with faced with corrupted file systems.  The ncheck command
560also now has a -c option which will verify the file type information
561in the directory entry to see if matches the inode's mode bits.  This
562is extremely useful when trying to use debugsfs to determine which
563parts of the file system metadata can be trusted.
564
565E2image will try to use ftruncate64() to set the i_size for raw
566images, instead of writing a single null byte.  This avoid allocating
567an extra block to the raw image, for those file systems and/or
568operating systems that support this.  (Linux does.)  In addition, fix
569a logic bug that caused the file to not be properly extended if the
570size of the last hole was exactly an multiple of a megabyte.
571
572Fixed a bug in resize2fs where for 1k and 2k file systems, where
573s_first_data_block is non-zero, this wasn't taken into account when
574calculate the minimum file system size for use with the -M option.
575
576Fixed the badblocks program to honor the -s flag when in read-only -t
577mode.  (Addresses Debian Bug #646629)
578
579Update Czech, Dutch, French, Polish, and Sweedish translation from the
580Translation Project.
581
582Fixed various Debian Packaging issues so that dpkg-buildflags is used
583if present, which allows e2fsprogs to be built with security hardening
584flags.  (Addresses Debian Bugs: #654457)
585
586Programmer's Notes
587------------------
588
589Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
590This was only an issue for programs compiled against e2fsprogs 1.41
591that manipulate bitmaps directly.  (Addresses Sourceforge Bugs:
592#3451486)
593
594The libext2fs library now uses sysconf() to fetch the page size, instead
595of the deprecated getpagesize().
596
597The ext2fs_get_pathname() function will return a partial path if an a
598directory in the path is not a directory, displaying it as an inode
599number in angle brackets instead of giving up and displaying an error.
600This is much more helpful when a user is trying to debug a corrupted
601file system.
602
603Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
604
605Added a new library function, ext2fs_file_get_inode_num(), for use by
606fuse2fs.
607
608Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
609file, it actually works.
610
611The block iterator now properly honors the BLOCK_ABORT flag for
612extent-based flags.  Previously, it didn't, which generally made code
613be less efficient, but it could cause bugs in ext2fs_link(), for
614example, by causing it to insert multiple directory entries.
615
616Fixed an (harmless other than causing a compiler warning) use of an
617uninitialized variable in e2fsck's MMP code.
618
619
620E2fsprogs 1.42 (November 29, 2011)
621==================================
622
623This release of e2fsprogs has support for file systems > 16TB.  Online
624resize requires kernel support which will hopefully be in Linux
625version 3.2.  Offline support is not yet available for > 16TB file
626systems, but will be coming.
627
628This release of e2fsprogs has support for clustered allocation.  This
629reduces the number of block (now cluster) bitmaps by allocating and
630deallocating space in contiguous power-of-2 collections of blocks,
631which are called clustered.  This is a file system level feature,
632called 'bigalloc', which must be enabled when the file system is
633initially formatted.  It is not backwards compatible with older
634kernels.
635
636Added support for the Multi-Mount Protection (MMP) feature.
637
638E2fsck more efficiently uses scratch files for really big file
639systems.  (This is a feature that has to be turned on explicitly; see
640[scratch_files] in the e2fsck.conf man page.)
641
642Fix a bug in e2fsck where if the free blocks and inodes counts are
643incorrect, e2fsck would fix them without printing an error message.
644This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
645any explanation of what was fixed.
646
647E2fsck will no longer attempt to clone an extended attribute block in
648pass1b handling if the file system does not support extended
649attributes.
650
651E2fsck will be more careful accidentally asking the user to continue
652if the file system is mounted, so that an escape sequence won't cause
653a false positive.  (Addresses Debian Bug: #619859)
654
655E2fsck now uses less cpu time in pass 5 when large portions of the
656bitmaps are uninitialized.
657
658E2fsck will no longer segault when a corrupted file system has a bad
659extent, and removing it leads to a block needing to be deallocated.
660(Addresses SourceForge Bug: #2971800)
661
662E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
663and print debugging information to make it easier to find potential
664problems.
665
666E2fsck will check to see if the bad block inode looks insane, and will
667skip trying to use if it certain fields which should be zero look
668non-zero.  This is to avoid a corrupted bad block inode causing e2fsck
669to get confused and do more harm than good.
670
671If e2fsck modifies certain superblock fields which the kernel doesn't
672look at, it will now mark the superblock as dirty without marking the
673file system as changed.  This avoids signalling the init scripts that
674a reboot is necessary, since the kernel isn't going to look at those
675fields, so it won't care if they have been changed.
676
677Fixed a bug in the libext2fs library (in the binary search routine of
678the icount abstraction) that could (very, very rarely) cause e2fsck to
679die in the middle of pass 1 or pass 2 processing.
680
681E2fsck will not try to do a discard operation if the -n option was
682specified on the command line.
683
684E2fsck now supports an extended "discard" option which will cause
685e2fsck to attempt discard all unused blocks after a full, successful
686file system check.
687
688E2fsck will check for the bad block inode to make sure it looks sane
689before trusting it, to avoid causing more harm than good to the file
690system.
691
692E2fsck now returns additional status bits in its exit code if it
693aborts early in the e2fsck run.
694
695E2fsck now correctly calculates the maximum file size in the case of
696the huge_file file system feature enabled without extents.
697
698The mke2fs and e2fsck programs now tries to use the punch hole command
699as a "discard" when operating on normal files.
700
701The e2image program now supports the qcow2 format, which is a more
702efficient way of capturing file system dumps.
703
704Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
705per-device defaults to be specified in the configuration file.
706
707Mke2fs now supports the reserved_ratio relation in the [defaults] and
708[fs_types] section in mke2fs.conf.
709
710Mke2fs now creates extent-mapped directories for the root and
711lost+found directories.
712
713Mke2fs will skip zero'ing the journal if the extended option
714"lazy_journal_init" is specified.  This can save a lot of time, but it
715does add a small amount of risk if the system crashes before the
716journal is overwritten entirely once.  It is epsecially useful for
717testing.
718
719Mke2fs will now create file systems that enable user namespace
720extended attributes and with time- and mount count-based file
721system checks disabled.
722
723Mke2fs will not set a stride or strip size of one block based on block
724device attributes obtained from sysfs.
725
726Mke2fs now displays a progress report during the discard process.
727
728Mke2fs now handles extreme file system parameters correctly which
729previously caused the inodes per group to drop below 8, leading to a
730segfault.  (The inodes per group must be a multiple of 8, but the code
731didn't correctly deal with an inodes per group count less than 8.)
732
733Mke2fs and tune2fs previously would give an error if the user tried
734setting the stride and stripe-width parameters to zero; but this is
735necessary to disable the stride and stripe-width settings.  So allow
736setting these superblock fields to zero.  (Addresses Google Bug:
737#4988557)
738
739Mke2fs now gives a warning if the auto-detected block size exceeds the
740system's page size.
741
742If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
743is the default), mke2fs will now set the s_max_mnt_count superblock
744field to -1, instead of 0.  Kernels older then 3.0 will print a
745spurious message on each mount then they see a s_max_mnt_count set to
7460, which will annoy users.  (Addresses Debian Bug: #632637)
747    
748The default mke2fs.conf now has entries for "big" and "huge", which
749are needed for very big file systems.
750
751The resize2fs program now has support for a new online resize ioctl
752that can support file systems > 16TB, once it arrives in v3.x kernels.
753
754Fixed bug which caused resize2fs to fail when shrinking an empty file
755system down to its minimal size.  (Addresses Sourceforge Bug #3404051)
756
757Fixed tune2fs's mount options parsing.  (Addresses Debian Bug: #641667)
758
759Allow tune2fs to remove external journals if the device can not be
760found.
761
762Debugfs's icheck will now correctly find inodes which use the
763searched-for block as an extended attribute block.
764
765Debugfs now has a new "punch" command which remove blocks from the
766middle of an inode.
767
768Debugfs now has a new "e2freefrag" command which analyzes the free
769space fragmentation of the file system, using the same code as the
770e2freefrag program.
771
772Debugfs now has a "filefrag" command which displays information about
773a file's fragmentation.
774
775Add support to build a metadata-only, read-only, stripped-down version
776of debugfs called rdebugfs.
777
778Fixed a potential stack overrun bug in debugfs.
779
780The badblocks program now correctly recovers from I/O errors when
781direct I/O is being used.  The badblocks command now also supports a
782-B option which forces the use of buffered I/O, and the -v option will
783provide a more detailed breakdown of read, write, and failed
784comparison errors.
785
786Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
787
788Added support for journals larger than 2GB.
789
790Support using both hard links and symlinks when installing e2fsprogs.
791
792Add overflow checking to tune2fs -i's fsck interval, which must fit in
793a 32-bit field.
794
795The debugfs command now has a new 'blocks' command which prints out
796data blocks of a particular inode in a format which is useful for
797scripting.
798
799Filefrag will report 0 extents correctly in verbose mode.  (Addresses
800RedHat Bugzilla: #653234)
801
802Filefrag has been fixed so its -v report prints the correct expected
803block number (previously there had been an off-by-one error).  In
804addition, it will now display the number of contiguous extents when -v
805is not specified.  This makes it consistent with the number of extents
806printed when the -v option was specified.  In addition, the number of
807contiguous extents is far more interesting/useful than the number of
808physical extents for very large files.  (Addresses Debian Bug:
809#631498, #644792)
810    
811Logsave's usage message has been fixed.  (Addresses Debian Bug:
812#619788)
813
814Avoid an infinite loop in ext2fs_find_block_device() if there are
815symlink loops in /dev caused by a buggy udev.
816
817Added a useful "fallocate" program to the contrib directory.
818
819Fixed an ABI compatibility problem in libext2fs which broke the dump
820program.  Also added back some macros which dump needed so it could
821compile against the latest version of ext2_fs.h (Addresses Debian Bug:
822#636418)
823
824Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
825Debian Bug: #641667)
826
827Added internationalization support for libcom_err error table strings.
828
829Fixed various spelling mistakes found in various output strings found
830by I18N translators.
831
832Update translations: French, Chinese, Germany, Indonesian, Swedish,
833Vietnamese, Polish, Dutch, Czech.  (Addresses Debian Bugs: #520985,
834#620659)
835
836Fixed various Debian Packaging issues.  (Addresses Debian Bugs:
837#614662, #632169, #641838, #627535, #629355)
838
839Updated/clarified man pages.  (Addresses Debian Bugs: #639411,
840#642193, #634883)
841
842Programmer's Notes
843------------------
844
845Initial support for quota as an integrated feature, where the quota
846files are hidden system files that are automatically maintained by
847e2fsck is present, although disabled by default.  It must be enabled
848by using the configure option --enable-quota.
849
850Reserved the on-disk fields for the metadata checksum and snapshot
851features, which are currently in development.
852
853The ext2fs library now has the new functions ext2fs_punch(),
854ext2fs_get_memzero() and ext2fs_file_get_inode().
855
856The ext2fs library now has support for calculating the crc32c checksum
857(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
858
859The I/O manager now supports the discard operation.
860
861Reserved file system code points for new 1st class quota feature.
862
863Shortened the compilation lines by moving the autoconf defines to
864a config.h header file.
865
866Fixed a potential free of an unitialized pointer in
867ext2fs_update_bb_inode().
868
869Fixed miscellaneous gcc -Wall and coverity warnings.
870
871Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
872
873Fixed a build failure when OMIT_COM_ERR is defined.
874
875Improved error checking and fixed memory leaks caused by error return
876paths.
877
878Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
879the fsync() to be skipped.
880
881Added a test for extent-mapped journals by mke2fs and tune2fs.
882
883Added a test for creating a large (over 4GB) journal using mke2fs.
884
885Added a test to make sure the inode size remains constant.
886
887The regression test script now prints the list of which tests failed.
888
889The regression test system now uses /tmp for its scratch files, which
890is often a tmpfs mounted file system and hence much faster.
891
892The i_e2image test was fixed so it works with valgrind.
893
894Tests that rely on debugfs are now skipped if debugfs wasn't built.
895
896Fixed the dependencies for "make check" so all required dependencies
897are built before running the gression tests.
898
899A link to com_err.h is installed in $(includedir) during a "make install".
900
901The po/*.gmo files are automatically rebuilt if they are missing or
902out of date.  This helps out Debian packaging.
903
904Allow ext2fs_get_memalign() to compile on systems that don't have
905posix_memalign().
906
907Fixed a namespace leak in libext2fs (tdb_null).
908
909
910E2fsprogs 1.41.14 (December 22, 2010)
911=====================================
912
913Fix spurious complaint in mke2fs where it would complain if the file
914system type "default" is not defined in mke2fs.conf.
915
916The resize2fs program will no longer clear the resize_inode feature
917when the number reserved group descriptor blocks reaches zero.  This
918allows for subsequent shrinks of the file system to work cleanly for
919flex_bg file systems.
920
921The resize2fs program now handles devices which are exactly 16T;
922previously it would give an error saying that the file system was too
923big.
924
925E2fsck (and the libext2fs library) will not use the extended rec_len
926encoding for file systems whose block size is less than 64k, for
927consistency with the kernel.
928
929Programming notes
930-----------------
931
932E2fsprogs 1.41.13 would not compile on big-endian systems.  This has
933been fixed.  (Addresses Sourceforge Bug: #3138115)
934
935The ext2fs_block_iterator2() function passed an incorrect ref_offset
936to its callback function in the case of sparse files.  (Addresses
937Sourceforge Bug: #3081087)
938    
939Fix some type-punning warnings generated by newer versions of gcc.
940
941
942E2fsprogs 1.41.13 (December 13, 2010)
943=====================================
944
945E2fsck now supports the extended option "-E journal_only", which
946causes it to only do a journal replay.  This is useful for scripts
947that want to first replay the journal and then check to see if it
948contains errors.
949
950E2fsck will now support UUID= and LABEL= specifiers for the -j option
951(which specifies where to find the external journal).  (Addresses
952Debian Bug #559315)
953
954E2fsck now has support for the problems/<problem code>/force_no
955configuration option in e2fsck.conf, which forces a problem to not be
956fixed.
957
958Dumpe2fs will now avoid printing large negative offsets for the bitmap
959blocks and instead print a message which is a bit more helpful for
960flex_bg file systems.
961
962Mke2fs will now check the file system type (specified with the -t
963option) to make sure it is defined in the mke2fs.conf file; if it is
964not, it will print an error and abort.  If the usage type (specified
965with the -T option) is not defined in mke2fs.conf, mke2fs will print a
966warning but will continue.  (Addresses Debian Bug #594609)
967
968Clarified error message from resize2fs clarifying that on-line
969shrinking is not supported at all.  (Addresses Debian Bug #599786)
970    
971Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
972displayed.  (Addresses Debian Bug #555456)
973
974E2fsck will open the external journal in exclusive mode, to prevent
975the journal from getting truncated while it is in use due to a user
976accidentally trying to run e2fsck on a snapshotted file system volume.
977(Addresses Debian Bug #587531)
978
979Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
980flag.
981
982The tune2fs program can now set the uninit_bg feature without
983requiring an fsck.
984
985The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
986default mount options settings which were added in 2.6.35.
987
988The e2fsck and dumpe2fs programs now support the new ext4 superblock
989fields which track where and when the first and most recent file
990system errors occurred.  These fields are displayed by dumpe2fs and
991cleared by e2fsck.  These new superblock fields were added in 2.6.36.
992
993Debugfs now uses a more concicse format for listing extents in its
994stat command.  This format also includes the interior extent tree
995blocks, which previously was missing from stat's output for
996extent-based files.
997
998Debugfs has a new option, -D, which will request Direct I/O access of
999the file system.
1000
1001Mke2fs will skip initializing the inode table if a device supports
1002discard and the discard operation will result in zero'ed blocks.
1003
1004Badblocks will now correctly backspace over UTF-8 characters when
1005displaying its progress bar.  (Addresses Gentoo Bug #309909; Addresses
1006Debian Bugs #583782 and #587834)
1007
1008E2freefrag will now display the total number of free extents.
1009
1010Resize2fs -P no longer requires a freshly checked filesystem before
1011printing the minimum resize size.
1012
1013Fixed a floating point precision error in a binary tree search routine
1014that can lead to seg fault in e2fsck and resize2fs.
1015
1016Fixed a bug in e2fsck where if both the original and backup superblock
1017are invalid in some way, e2fsck will fail going back to the original
1018superblock because it didn't close the backup superblock first, and
1019the exclusive open prevented the file system from being reopened.
1020
1021Fixed a big in e2freefrag which caused getopt parsing to fail on
1022architectures with unsigned chars.  (Addresses Gentoo Bug: #299386)
1023
1024Clarified an mke2fs error message so a missed common in an -E option
1025(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
1026results in a more understandable explanation to the user.
1027
1028Mke2fs now displays the correct valid inode ratio range when
1029complaining about an invalid inode ratio specified by the user.
1030
1031Mke2fs now understands the extended option "discard" and "nodiscard",
1032and the older option -K is deprecated.  The default of whether
1033discards are enabled by default can be controled by the mke2fs.conf
1034file.
1035
1036Mke2fs's handling of logical and physical sector sizes has been
1037improved to reflect the fact that there will be some SSD's with 8k and
103816k physical sectors arriving soon.  Mke2fs will no longer force block
1039size to be the physical sector size, since there will be devices where
1040the physical sector size is larger than the system's page size, and
1041hence larger than the maximal supported block size.  In addition, if
1042the minimal and optimal io size are not exported by the device, and
1043the physical sector size is larger than the block size, the physical
1044sector size will be used to set the Raid I/O optimization hints in the
1045superblock.
1046
1047E2fsck will now display a better, more specific error message when the
1048user enters a typo'ed device name, instead of blathering on about
1049alternate superblocks.
1050
1051Fixed various Debian Packaging Issues
1052
1053Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
1054#589345, #591083; Addresses Launchpad Bug: #505719)
1055
1056Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
1057Polish, Swedish, and Vietnamese translations.

1060Programmer's Notes
1061------------------
1062
1063Fix a dependency definition for the static and profiled blkid
1064libraries which could cause compile failures in some configurations.
1065(Addresses Debian Bug: #604629)
1066    
1067Add support for Direct I/O in the Unix I/O access layer.
1068
1069Fixed a memory leak in the Unix I/O layer when changing block sizes.
1070
1071Fixed minor memory leaks in mke2fs.
1072
1073Added a new function to the ext2fs library, ext2fs_get_memalign().
1074
1075The tst_super_size test program will check to make sure the superblock
1076fields are correctly aligned and will print them out so they can be
1077manually checked for correctness.
1078
1079Fixed some makefile dependencies for test programs in lib/ext2fs.
1080
1081Reserved the feature flags and superblock fields needed for the Next3
1082snapshot feature.
1083
1084Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
1085EXT4_INCOMPAT_EA_INODE.
1086
1087
1088E2fsprogs 1.41.12 (May 17, 2010)
1089================================
1090
1091Mke2fs now gives a correct error message if the external journal
1092device is not found.  (Addresses Red Hat Bug #572935)
1093
1094Resize2fs -P will now refuse to print a minimum size if the file
1095system is not clean.  Previously it would go ahead and print a minimum
1096size anyway, which might not be correct, leading to user confusion.
1097
1098E2fsck now tests for extents that begin at physical block 0 and
1099rejects them as invalid.  (Addresses Google Bug: #2573806)
1100    
1101Fixed a bug in e2fsck which could cause it to crash when trying to
1102remove an invalid extent and the block bitmaps hadn't yet been loaded.
1103(Addresses SourceForge Bug: #2971800)
1104    
1105E2fsck now will completely skip time-based checks if the system clock
1106looks insane or the option broken_system_clock is set in
1107/etc/e2fsck.conf.
1108
1109E2fsck would previously report an i_blocks corruption for a 4T file
1110created using posix_fallocate; this bug has been fixed.
1111
1112E2fsck will now correctly mark a sparse journal as invalid and will
1113delete and recreate the journal to address the problem.
1114
1115E2fsck would previously incorrectly ask the user whether she would
1116like to abort the file system check after finding a problem --- and
1117then abort regardless of the user's answer.  This is annoying, and
1118has been fixed.
1119
1120E2fsck can now continue even if it fails to recreate the resize
1121inode; previously it would just abort the file system check
1122altogether.
1123
1124E2fsck could potentially remove directory entries for inodes found in
1125the unused region of the inode table; this would generally happen on
1126ext4 file systems that do not use journaling.  This bug has been fixed
1127by not clearing these directory entries once it has been established
1128that bg_unused_inodes may not be trustworthy; once pass #2 has been
1129completed, e2fsck will restart the file system check from the
1130beginning, and then it will be safe to delete any directory entries
1131pointing to inodes that appear to be deleted.  (Addresses Google Bug:
1132#2642165)
1133    
1134E2fsck will not try to set the block group checksums if the user
1135cancels the fsck with a control-C.  It's a bad idea to set the
1136checksums if e2fsck hasn't been completed, and it often results an the
1137error message, "Inode bitmap not loaded while setting block group
1138checksum info".  (Addresses Launchpad Bug: #582035)
1139
1140The mke2fs program now queries the kernel for the physical as well as
1141the logical sector size, and will not allow a blocksize below the
1142logical, and will strongly encourage a blocksize at least as big as
1143the physical blocksize.  This is needed for 4k sector drives that
1144emulate 512 byte sector sizes.
1145
1146Mke2fs will now allow a flex_bg size of 1.  This is unusual, and
1147rarely needed, but it is a legal value.
1148
1149E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1150not needed, and offer to clear it; this is a sign of a kernel bug, but
1151more importantly, some released kernels may crash when this situation
1152is encountered on ext4 file systems.  (Addresses Google Bug: #2604224)
1153    
1154E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1155i_size is correct.  (Kernels starting with 2.6.34 will set
1156EOFBLOCKS_FL.)
1157
1158The com_err library will now only output ^M (a CR character) when the
1159tty is in raw mode.
1160
1161Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
1162and Vietnamese translations.
1163
1164Fixed various Debian packaging issues --- see debian/changelog for
1165details.  (Addresses Debian Bugs: #571247, #563487)
1166
1167
1168Programmer's Notes
1169------------------
1170
1171The regression test suite now uses its own mke2fs.conf file, so that
1172downstream distributions want change the mke2fs.conf file which is
1173distributed in the RPM or dpkg file, without worrying about screwing
1174up the regression test results.
1175
1176Always build namei.o so that building with configure --disable-debugfs
1177works correctly.  Long-term, if we care about reduced e2fsprogs
1178builds, we need a more general solution for deciding what .o files are
1179needed for a particular build.  Given that install floppies are going
1180(gone?) the way the dodo bird, we probably don't care, though.
1181(Addresses Sourceforge Bug: #2911433)
1182
1183Add configure options --enable-symlink-build and
1184--enable-symlink-install, which allow e2fsprogs be built using
1185symlinks instad of hard links, and to be installed using symlinks
1186instead of hard links, respectively.  It is useful when the file
1187system where the build is taking place, or the file system where
1188e2fsprogs is installed, can't handle hard links for some reason.
1189(Addresses Sourceforge Bug: #1436294)
1190
1191Fixed compile warning in mke2fs.c.
1192
1193    
1194E2fsprogs 1.41.11 (March 14, 2010)
1195==================================
1196
1197E2fsck will no longer give a fatal error and abort if the physical
1198device has been resized beyond 2**32 blocks.  (Addresses Launchpad
1199Bug: #521648)
1200
1201Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
1202the allocation status of the block <blk>.  (Addresses Debian Bug:
1203#564084)
1204    
1205E2fsck now prints a much more emphatic and hopefully scary message
1206when a file system is detected as mounted while doing a read/write
1207check of the filesystem.  Hopefully this will dissuade users from
1208thinking, "surely that message doesn't apply to *me*" :-(
1209
1210E2fsck -n will now always open the file system read-only.  We now
1211disallow certain combination of options which previously were manual
1212exceptions; this is bad because it causes users to think they are
1213smarter than they really are.  So "-n -c", "-n -l", "-n -L", and "-n
1214-D" are no longer supported.  (Addresses Launchpad Bug: #537483)
1215    
1216In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
1217it detected a badly aligned partition.  Unfortunately, this broke some
1218distribution installation scripts, so it now just prints the warning
1219message and proceeds.  (Addresses Red Hat Bug: #569021. Addresses
1220Launchpad Bug: #530071)
1221    
1222Mke2fs would take a long time to create very large journal files for
1223ext4.  This was caused by a bug in ext2fs_block_iterate2(), which is
1224now fixed.
1225
1226E2fsck now understands the EOFBLOCKS_FL flag which will be used in
12272.6.34 kernels to make e2fsck not complain about blocks deliberately
1228fallocated() beyond an inode's i_size.
1229
1230E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1231e2fsck -fD can corrupt non-indexed directories when are exists one or
1232more file names which alphabetically sort before ".".  This can happen
1233with ext2 filesystems or for small directories (take less than a lock)
1234which contain filenames that begin with a space or some other
1235punctuation mark.  (Addresses Debian Bug: #573923, Addresses Launchpad
1236Bug: #525114)
1237
1238
1239Programmer's Notes
1240------------------
1241
1242Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
1243correctly.
1244
1245The libcom_err function now has support for Heimdal's com_right_r
1246function().  (Addresses Sourceforge Bug: #2963865, Addresses Debian
1247Bug: #558910)
1248
1249
1250E2fsprogs 1.41.10 (February 7, 2010)
1251====================================
1252
1253Fix resize2fs bug which causes it to access invalid memory.
1254
1255Add libss support for libreadline.so.6.
1256    
1257Fix e2fsck's check for extent-mapped directory with an incorrect file
1258type.
1259
1260Add new e2fsck.conf configuration option, default/broken_system_clock
1261to support systems with broken CMOS hardware clocks.  Also, since too
1262many distributions seem to have broken virtualization scripts now,
1263e2fsck will by default accept dates which are off by up to 24 hours by
1264default.  (Addresses Debian Bugs: #559776, #557636)
1265
1266Fix a bug where mke2fs may not use the best placement of the inode
1267table when there is only room for a single block group in the last
1268flex_bg.
1269
1270E2fsck is now smarter when it needs to allocate blocks in the course
1271of fixing file system problems.  This reduces the number of spurious
1272differences found in pass #5.
1273
1274E2fsck will no longer rehash directories which fit in a single
1275directory block.
1276
1277E2fsck now correctly handles holes in extent-mapped directories (i.e.,
1278sparse directories which use extents).
1279
1280Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
1281
1282Fix a bug in filefrag where on platforms which can allow file systems
1283with 8k blocks, that it doesn't core dump when it sees a file system
1284with 8k block sizes.  (Thanks to Mikulas Patocka for pointing this
1285out.)
1286
1287E2fsck will correctly fix directories that are have an inaccurate
1288i_size as well as other problems in a single pass, instead of
1289requiring two e2fsck runs before the file system is fully fixed.
1290
1291Fix e2fsck so it will correctly find and detect duplicate directory
1292entries for non-indexed directories.  ( Addresses Sourceforge Bug:
1293#2862551)
1294    
1295Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
1296thinly-provisioned storage device.  This can be disabled using the -K
1297option.
1298
1299Enhance libext2fs so it works around bug in Linux version 2.6.19
1300and earlier where the /proc/swaps file was missing the header on
1301the first line.
1302
1303Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
1304was missing the header on the first line.
1305
1306Fix some big-endian bugs in e2fsck and libext2fs.
1307
1308Fix resize2fs so it works correctly on file systems with external
1309journals instead of failing early with the error "Illegal inode
1310number".
1311
1312Fix libss so that it does not seg fault when using a readline library
1313which does not supply a readline_shutdown() function.
1314
1315Updated dumpe2fs's usage message so it correctly gives the right
1316arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
1317(Addresses Launchpad Bug: #448099)
1318   
1319Teach libext2fs to ignore the high 32 bits of the i_blocks field
1320when huge_file file system feature is set, but the inode does not
1321have the HUGE_FILE_FL flag set.
1322
1323Fix e2fsck's handling of 64-bit i_blocks fields.
1324
1325E2fsck will now print "Illegal indirect block", "Illegal
1326double-indirect block", etc., instead of "Illegal block #-1" or
1327"Illegal block #-2", etc.  This makes it easier for users to
1328understand what has gone wrong.  (Addresses SourceForge Bug: #2871782)
1329
1330Mke2fs now will obtain get device topology information from blkid and
1331use it to populate the superblock stride and stripe sizes.  It will
1332also warn if the block device is misaligned
1333
1334Fix file descriptor leaks in fsck and debugfs.  (Addresses Novell Bug:
1335##524526)
1336
1337Fix the libext2fs library code to round up the bitmap size to a 4-byte
1338boundary, to prevent spurious seg faults caused by the x86
1339architecture.  This doesn't affect Linux systems, but was a major
1340problem on a number of *BSD systems.  (Addresses Sourceforge Bug:
1341#2328708)
1342
1343Fix resize2fs's minimum size required for a file system so it doesn't
1344fail when "resize2fs -M" is run.  (Addresses RedHat Bugzilla: #519131)
1345    
1346Dumpe2fs now prints summary information about the contents of the
1347journal.
1348    
1349Avoid printing scary error messages when e2fsck starts running
1350problems on low-memory systems, as it tends to panic and mislead the
1351user.  (Addresses Debian Bug: #509529)
1352
1353Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
1354modules files.  (Address Red Hat Bug: #518572)
1355    
1356Fix tune2fs so it can add a journal when an extent-enabled file system
1357is mounted.  (Addresses Launchpad bug: #416648)
1358
1359Update Czech, Indonesian, Polish and Vietnamese translations (from the
1360Translation Project).
1361    
1362Update/clarify man pages.  (Addresses Sourceforge Bug: #2822186)
1363

1365details.  (Addresses Debian Bugs: #540111)
1366
1367Programmer's Notes
1368------------------
1369
1370The configure script supports the --with-cc, --with-ccopts, and
1371--with-ldopts options.  Instead, the more standard use of CC=,
1372CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
1373Also, --with-ld, which never worked, was also removed.
1374(Addresses Sourceforge Bug: #2843248)
1375
1376The in-tree header files are only used if the in-tree uuid or blkid
1377libraries are used.  Otherwise, use the system-provided uuid or blkid
1378header files if using the system-provided libraries.
1379
1380Fix some build failures caused by --disable-* configure options.
1381
1382Work around a bug in autoconf 2.64.
1383
1384
1385E2fsprogs 1.41.9 (August 22, 2009)
1386==================================
1387
1388Fix a bug in e2fsck routines for reallocating an inode table which
1389could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1390filesystem feature with a relatively rare (and specific) filesystem
1391corruption.  This fix causes e2fsck to try to find space for a new
1392portion of the inode table in the containing flex_bg, and if that
1393fails, the new portion of the inode table will be allocated in any
1394free space available in the filesystem.
1395
1396Make e2fsck less annoying by only asking for permission to relocate a
1397block group's inode table once, instead of for every overlapping
1398block.  Similarly, only ask once to recompute the block group
1399checksums, instead of once for each corrupted block group's checksum.
1400
1401Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1402not present, and it needs to fall back to using the FIBMAP ioctl.
1403
1404Fix filefrag to correctly print the number of extents for zero-length
1405files.  (Addresses Debian Bug: #540376)
1406
1407Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1408to more easily debug the FIBMAP code.
1409
1410Fixed filefrag for non-extent based files.
1411
1412Add a new program, e2freefrag, which displays information about the
1413free space fragmentation in an ext2/3/4 filesystem.
1414
1415Fix inode resizing via tune2fs -I so that it works correctly in the
1416face of non-empty bad blocks inodes, and if the filesystem was
1417formatted using the "mke2fs -E stride=N" option for RAID arrays.
1418
1419Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1420and corrupt large directories if the directory needs to shrink by more
1421than one block.  (Addresses Debian Bug: #537510)
1422    
1423Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1424last mount times are in the future, they are corrected even if
1425buggy_init_scripts is set.  This is needed because otherwise resize2fs
1426will refuse to resize the filesystem, even after running "e2fsck -f".
1427(Addresses Launchpad bug: #373409)
1428
1429E2fsck will now print much fuller information when the last mount time
1430or last written time is in the future, since most people can't seem to
1431believe their distribution has buggy init scripts, or they have a
1432failed CMOS/RTS clock battery.
1433
1434Enhance dumpe2fs to dump the extent information via the 'stat'
1435command, and more detailed extent information via the new command
1436'dump_extents'.
1437    
1438Update French, Polish, Czech, and Sweedish translation from the
1439Translation Project.
1440
1441Fixed various Debian packaging issues --- see debian/changelog for
1442details.
1443
1444Programmer's Notes
1445------------------
1446
1447Fixed miscellaneous gcc -Wall warnings.
1448
1449Fixed memory leak in error path in ext2fs_block_iterate2()
1450
1451Fixed non-Linux build of the intl directory by adding support for the
1452E/Q/V macros.
1453
1454The bitmap read/write functions now treat uninitialized bitmaps as
1455unallocated; this fixes a number of problems in all e2fsprogs for ext4
1456filesystems when there is a need to allocate new blocks or inodes, and
1457there aren't any free blocks or inodes in the already-used block
1458groups.
1459
1460Improve ext2fs_extent_set_bmap() to avoid creating new extents which
1461get inserted into the extent tree when they are not needed.
1462    
1463
1464E2fsprogs 1.41.8 (July 11, 2009)
1465================================
1466
1467Fix resize2fs's online resizing, fixing a regression which in
1468e2fpsrogs 1.41.7.   (Addresses Debian Bug: #535452)
1469
1470Fix potential filesystem corruptions caused by using resize2fs to
1471shrinking ext4 filesystems with extents enabled.  (Addresses Red Hat
1472Bug: #510379)
1473
1474Optimize uuid_generate() to avoid running uuidd if it is not setuid or
1475setgid and the currently running program doesn't have write access to
1476the uuidd work directory.
1477
1478Add safety checks (for non-Linux systems) so that uuidd isn't run with
1479file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1480will be careful not to close the file descriptor for its unix domain
1481socket when it detaches itself from the controlling tty.  Also add
1482safety checks so that if the unix domain socket between the uuid
1483library and uuidd program is closed for any reason, both the library
1484and the uuidd will return an appropriate error code instead of looping
1485in an infinite loop.
1486
1487The e2croncheck script, which creates an LVM snapshot and then checks
1488the ext3/4 filesystem via the LVM snapshot, has been added to the

1501Programmer's Notes
1502------------------
1503
1504Fix compilation problem when configured with --disable-uuid.
1505
1506Don't build uuidgen if configured with --disable-uuid.
1507
1508Add the new library function ext2fs_test_inode_bitmap_range(), and
1509optimized ext2fs_test_block_bitmap_range(), which will be needed for
1510future optimizations for e2fsck.
1511
1512Fix makefile dependencies for libcom_err so that the Makefiles work
1513well on non-GNU make program.  (Addresses Sourceforge Patches: #2813809)
1514
1515Enhance the build system so that the full set of commands executed by
1516the Makefiles are displayed, instead of the Linux kernel summary
1517output, if the build was configured with --enable-verbose-makecmds, or
1518if GNU make is in use and the V variable is non-null, i.e., via "make
1519V=1".

1521
1522E2fsprogs 1.41.7 (June 29, 2009)
1523================================
1524
1525Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
1526uninitalized data into the portion of the inode beyond the first 128
1527bytes when operating on inodes mapped via extents; potentially
1528corrupting filesystems.
1529
1530Fix memory leaks in e2fsprogs, including a very large memory leak
1531which can cause e2fsck to run out of memory when checking very large
1532filesystems using extents.
1533
1534The logsave program will now filter out the ^A and ^B characters when
1535writing to the console.
1536
1537Harden ext2fs_validate_entry() so that lsdel will not read beyond the
1538end of the block even if the directory block is corrupted.
1539
1540Fix debugfs from core dumping if the logdump command fails to open the
1541output file.
1542
1543Enhance badblocks to print the currently tested block number when
1544interrupted with ^C.
1545
1546Fix lsattr to exit with a non-zero status when it encounters errors.
1547(Addresses RedHat Bugzilla #489841)
1548
1549Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
1550filesystems as the kernel when encoding rec_len >= 64k.  For 64k
1551filesystems (currently all that is supported by e2fsprogs, this is
1552only a minor corner case).
1553
1554Resize2fs will now update the journal backup fileds in the sup0erblock
1555if the journal is moved; this avoids an unnecessary full fsck after
1556resizing the filesystem.  (Addresses RedHat Bugzilla: #505339)
1557    
1558Fix libext2fs to properly initialize i_extra_size when creating the
1559journal and resize inodes.
1560
1561Change badblocks to allow block sizes larger than 4k.
1562
1563Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
1564
1565Update Chinese and Czech translation from the Translation Project.
1566
1567Clean up various man pages.  (Addresses Debian Bug #531385 and #523063)

1570Programmer's Notes
1571------------------
1572
1573Add --disable-libuuid option to configure which uses an in-system
1574installed version of libuuid; the private version is enabled by
1575default.
1576
1577Add --valgrind-leakcheck option to the test_script program which runs
1578valgrind with the appropriate options to find memory leaks.
1579
1580
1581E2fsprogs 1.41.6 (May 30, 2009)
1582===============================
1583
1584Fix a critical regression in e2fsck introduced version 1.41.5 which
1585can undo updates to the block group descriptors after a journal replay.
1586
1587If e2fsck receives an I/O error while replaying the journal, prompt
1588the user whether they want to ignore the error or not; if e2fsck is
1589run in preen mode, force fsck to abort the preen pass.
1590
1591Fix a bug which would cause e2fsck to core dump if the filesystem
1592contains a corrupt extent header, and the user declines to clear the
1593inode.  (Addresses Sourceforge Bug: #2791794)
1594    
1595Fix e2fsck to restart only once in the case of multiple block groups
1596which inodes in use that are in the uninitialized part of the block
1597group's inode table.
1598
1599To reduce user confusion, if the /etc/mtab file is missing
1600ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1601new, explicit error code to indicate this case.  This will cause
1602e2fsck to give a clearer error message when the user is using buggy
1603rescue CD's that don't properly set up /etc/mtab.  (Addresses Debian
1604Bug: #527859)
1605    
1606Fix e2fsck so that if the primary group descriptors are corrupted, but
1607the backup superblock is entirely invalid, to go back to using (and
1608fixing) the priary group descriptors instead of completely giving up
1609on the filesystem.  (Addresses Debian Bug: #516820)
1610    
1611Change e2fsck to not abort a preen pass if an inode is found to have
1612i_file_acl_hi non-zero.  Ext3 filesystems don't care, and newer
1613kernels (post 2.6.29) will ignore this field.  So let's fix it
1614automatically during the preen pass instead of forcing the user to fix
1615this up manually.  (Addresses Debian Bug: #526524)
1616    
1617Add resource tracking for e2fsck passes 1b through 1d.
1618
1619Speed up e2fsck by eliminating unnecessary journal checks if the
1620filesystem is already mounted and doesn't need recovery (since the
1621kernel would have run the journal when the filesystem was mounted.)
1622Also speed up e2fsck by avoiding unnecessary block group descriptor
1623updates in ext2fs_close().
1624
1625Add support to chattr to migrate inodes from using direct/indirect
1626blocks to extents.
1627
1628Avoid corrupting the filesystem if there is an attempt to shrink a
1629filesystem using resize2fs smaller than posible by making
1630ext2fs_set_bmap() more careful not to delete the old block until the
1631new block can be inserted.  In addition, fix a bug in how the minimum
1632size of the filesystem (plus a safety margin) is calculated, and
1633modify resize2fs to refuse to shrink the filesystem below that minimum
1634size without the force flag.
1635
1636Teach blkid to try to figure out DM device names using take advantage
1637of information in sysfs when running on kernels (2.6.29 and later)
1638which provide this information in /sys/block/dm-<N>/dm/name; this is
1639much faster than scanning for the devncie number in /dev/mapper.
1640
1641Fix blkid to prefer /dev/mapper/<name> device names instad of the
1642private /dev/dm-X names.
1643
1644Add an -a option to debugfs's close_filesys command which writes any
1645changes to the superblock or block group descriptors to all of the
1646backup superblock locations.
1647    
1648Add support to the filefrag program to use the FIEMAP ioctl.
1649
1650Update Chinese translation from the Translation Project.
1651
1652Clean up various man pages.  (Addresses Red Hat Bugzilla: #502971 and
1653Launchpad Bug: #381854)
1654
1655Fixed various Debian packaging issues --- see debian/changelog for
1656details.  (Addresses Debian Bug #506064)
1657
1658
1659Programmer's Notes
1660------------------
1661
1662Add test code to make sure e2fsck's problem.c doesn't have two problem
1663codes assigned to duplicate values.
1664
1665Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1666(Addresses Sourceforge Bug: #2780205)
1667
1668Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1669function declaration for init_resource_track() and
1670print_resource_track() when RESOURCE_TRACK is not defined.
1671
1672The test code which is used to build the tst_csum progam has been
1673moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1674avoid compile problems caused by not having a prototype for
1675ext2fs_group_desc_csum().  (Addresses Sourceforge Bug #2484331)
1676
1677Update the config.guess and config.sub file to the latest from the
1678FSF, to allow e2fsprogs to build on the avr32 platform.  (Addresses
1679Debian Bug: #528330)
1680
1681Add a new function, ext2fs_extent_open2(), which behaves like
1682pext2fs_extent_open(), but uses the user-supplied inode structure
1683when opening an extent instead of reading the inode from disk.
1684
1685
1686E2fsprogs 1.41.5 (April 23, 2009)
1687=================================
1688
1689Fix a number of filesystem corruption bugs in resize2fs when growing
1690or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1691is not mounted).
1692
1693Debugfs can now set i_file_acl_high via the set_inodes_field command,
1694and print a 64-bit file acl.  This is useful for debugging filesystem
1695corruptions where the high bits of i_file_acl_high are set.  E2fsck
1696will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1697since some Linux kernel versions pay attention to this field even when
1698they shouldn't.
1699
1700Speed up e2fsck when checking clean filesystems by avoiding
1701unnecessary block reads, and coalescing the block group descriptor
1702blocks so they are read using a single read operation.
1703
1704The libuuid library will now close all file descriptors before running
1705uuidd.  This avoids problems when the calling program has open sockets
1706which then never get closed because uuidd is a long-running helper
1707daeomn.  (Addresses Launchpad bug: #305057)
1708
1709In order to avoid unnecessary full filesystem checks by e2fsck after
1710an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1711the backup superblocks.  (Addresses Red Hat Bugzilla: #471925)
1712
1713Mke2fs will avoid trying to create the journal when run in
1714superblock-only mode (mke2fs -S), since the left-over journal in the
1715inode table will cause mke2fs to fail.
1716
1717Fix a bug in libext2fs functions that check to see if a particular
1718device or filesystem image is mounted, which would cause these
1719functions to report that a file identical to the (relative) pathname
1720used by a pseudo-filesystem was mounted when in fact it was not.
1721
1722Update Czech translation from the Translation Project.
1723
1724Add Chinese (simplified) translation from the Translation Project.
1725
1726Fix support for external journals (which was broken in e2fsprogs
17271.41.4).
1728
1729Fix a regression in debugfs where the "stat" command when no
1730filesystem was open would cause debugfs to crash with a segmentation
1731violation.
1732
1733Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1734used to support filesystems without a journal.  Update the blkid
1735library so it understands this.
1736
1737The blkid library will remove an entry from the blkid cache
1738representing the entire disk if partitions are found, since presuambly
1739the device previously had no partition table, but has now transitioned
1740to using a partition table.
1741
1742Add a check to mke2fs and tune2fs that the argument to the -m option
1743(which specifies the reserved ratio) must be greater than zero.
1744(Addresses Debian Bug: #517015)
1745
1746Add support for tracking the number kilobytes written to the
1747filesystem via the superblock field s_kbytes_written.  It will be
1748updated by the kernel as well as by e2fsprogs programs which write to
1749the filesystem.  This is useful for tracking the wear to filesystems
1750on Solid Sstate Drives.
1751
1752Fix compatibility issue in the libext2fs info file and makeinfo
1753version 4.12.  (Addresses Red Hat Bugzilla: #481620)
1754
1755Update/clarify man pages.  (Addresses Debian Bug: #515693, #365619)
1756
1757Fixed various Debian packaging issues --- see debian/changelog for
1758details. (Addresses Debian Bug: #506279)
1759
1760Programmer's Notes
1761------------------
1762
1763Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
1764Bug: #521602)
1765
1766Fix various gcc compilation warnings and other programming cleanups.
1767(Addresses Red Hat Bugzilla: #486997)
1768
1769Add support for building the blkid command statically.
1770
1771Add support for disabling the built-in blkid library in favor of a
1772system-installed blkid implementation via the configure option
1773--disable-libblkid.
1774
1775
1776E2fsprogs 1.41.4 (January 27, 2009)
1777===================================
1778
1779Fixed a bug which could sometimes cause blkid to return an exit value
1780of zero for a non-existent device (Addresses Debian Bug: #502541)
1781
1782Blkid will now recognize ext3 filesystems that have the test_fs flag
1783set as ext3 filesystems.
1784
1785The blkid library will now recognize btrfs filesystems and swap
1786devices currently used by user-level software suspend.
1787
1788Tune2fs now updates the block group checksums when changing the UUID
1789to avoid causing e2fsck to complain vociferously at the next reboot.
1790
1791Tune2fs's inode size resizing algorithms have been fixed so it is not
1792vastly inefficient for moderate-to-large filesystems, due to some
1793O(n**2) and O(n*m) algorithms that didn't scale well at all.
1794
1795Fix tune2fs's inode resizing algorithm so it will not corrupt
1796filesystems laid out for RAID filesystems; in addition, tune2fs will
1797refuse to change the inode size for filesystems that have the flex_bg
1798feature enabled.  (This is a limitation in the current implementation
1799of tune2fs -I.)
1800
1801E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1802filesystems with 32-bit block numbers, when the headers for 64-bit
1803block numbers was added.  This regression has been fixed.
1804
1805Debugfs's ncheck command has been fixed to avoid printing garbage
1806characters at the end of file names.
1807
1808Fix resize2fs for ext4 filesystems.  Some blocks that that need moving
1809when shrinking filesystems with uninit_bg feature would not be moved.
1810In addition, blocks and inode table blocks were not being correctly
1811freed when shrinking filesystems with the flex_bg feable, which caused
1812resize2fs -M to fail.  Finally, when blocks are moved, make sure the
1813uninitialized flag in extents is preserved.
1814
1815Fix bug which caused dumpe2fs to abort with an error if run on a
1816filesystem that contained an external journal.
1817
1818Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1819for this in argv[0] to provide better legacy support for these
1820distributions.  This is a practice that should NOT be continued,
1821however.
1822
1823Mke2fs now has a new option -U, which allows the user to specify the
1824UUID that should be used for the new filesystem.
1825
1826Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1827minus one block.  This allows users who have read that ext3 supports
1828up to 16TB filesystems and who create a 16TB LVM to not get confused,
1829since the true limit is really 16TB minus one block.
1830
1831E2fsck will no longer abort an fsck run if block group has an errant
1832INODE_UNINIT flag.
1833
1834E2fsck now distinguishes between fragmented directories and fragmented
1835files in verbose mode statistics and in the fragcheck report.
1836
1837Fix a bug in e2fsck which casued it double count non-contiguous
1838extent-based inodes.
1839
1840E2fsck will leave some slack space when repacking directories to allow
1841room for a few directory entries to be added without causing leaf
1842nodes to be split right away.
1843
1844Fix a bug which caused e2fsck to crash when it comes across a
1845corrupted interior node in an extent tree with the error message:
1846"Error1: Corrupt extent header on inode XXXXXX"
1847
1848E2fsck problem descriptions involving the journal are no longer
1849referred to as "ext3" problems, since ext4 filesystems also have
1850journals.
1851
1852Fix a long-standing bug in e2fsck which would cause it to crash when
1853replying journals for filesystems with block sizes greater than 8k.
1854
1855Update Catalan translation from the Translation Project.
1856
1857Fixed various Debian packaging issues --- see debian/changelog for
1858details. (Addresses Debian Bugs: #503057, #502323, #511207)
1859
1860Programmer's Notes
1861------------------
1862
1863Fix build of e2fsck.profiled, and add support for building profiled
1864binaries in the misc directory if configured with --enable-profile.
1865
1866The ext2fs_open() function now performs more sanity checks on the
1867superblock to avoid potential divide by zero errors by other parts of
1868library.
1869
1870The ext2fs_read_inode_full() function now has a safety check to avoid
1871a segmentation fault on corrupted filesystems.
1872
1873The ext2fs_new_inode() function now has a sanity check so that if the
1874s_first_inode field in the superblock is insane, it will return
1875EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1876
1877To avoid segmentation faults, ext2fs_block_alloc_stats() and
1878ext2fs_inode_alloc_stats() now validates the passed inode or block
1879number to avoid overrunning an array boundary.
1880
1881Various signed/unsigned errors for variables containing block numbers
1882have been fixed.
1883
1884Accomodations for gcc's stupidity in not realizing that constant
1885strings that do not contain a '%' character are safe to use in format
1886strings have been made so that distributions that want to compile
1887e2fsprogs with -Werror=format-security have an easier time doing so.
1888
1889Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1890
1891Added the utility make-sparse.c to the contrib directory.
1892
1893The ext2fs_block_iterate2() function now reflects errors from
1894ext2fs_extent_set_bmap() to the caller, if the callback tries to
1895change a block on an extent-based file, and ext2fs_extent_set_bmap()
1896fails for some reason (for example, there isn't enough disk space to
1897split a node and expand the extent tree.
1898
1899The ext2fs_block_iterate2() function will preserve the uninit flag in
1900extents when the callback function modifies a block in an extent-based
1901file.
1902
1903E2fsck will now flag filesystems that have an insane s_first_ino field
1904in their superblock, and attempt to use a backup superblock to repair
1905the filesystem.
1906
1907
1908E2fsprogs 1.41.3 (October 12, 2008)
1909===================================
1910
1911E2fsck has been fixed so it prints the correct inode number for
1912uinit_bg related problems.
1913
1914E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1915is available on linux.  This can be disabled via a configuration
1916option in /etc/e2fsck.conf.
1917
1918Fix a file descriptor leak in libblkid when checking to see if an ext4
1919or ext4dev module exists.
1920
1921Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1922while trying to close a filesystem can lead to infinite loops.
1923(Addresses Red Hat Bugzilla #465679)
1924    
1925Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1926will cause resize2fs to drop into an infinite loop.  (Addresses Red
1927Hat Bugzilla: #465984)
1928    
1929Add a check in the Unix I/O functions in libext2fs so that when a
1930device is opened read/write, return an error if the device is
1931read-only using the BLKROGET ioctl.
1932
1933Fix debugfs's ncheck command so that it prints all of the names of
1934hardlinks in the same directory.
1935
1936Fix a bug in libblkid so it correctly detects whether the ext4 and
1937ext4dev filesystems are available, so that the ext4dev->ext4
1938fallback code works correctly.
1939
1940Programmer's Notes
1941------------------
1942
1943Fix a parallel build problem by making sure util/subst is built before
1944trying to build the lib/et directory.  (Addresses Sourceforge Bug:
1945#2143281)
1946
1947Updated "make depend" information for crc16.o
1948    
1949
1950E2fsprogs 1.41.2 (October 2, 2008)
1951==================================
1952
1953Fix e2fsck's automatic blocksize detection.  This fixes a regression
1954from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1955specifies a block number using the -b option if the blocksize option
1956isn't also specified using -B.  Unfortunately, users very commonly
1957invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1958superblock; in fack e2fsck will often suggest this kind of command
1959line.  Oops.
1960
1961Enhance the debugfs's "ncheck" command so it will print all of the
1962pathnames for the specified inodes.  (Previously, in some cases ncheck
1963might not print a pathname for an inode at all if some of the other
1964inodes had multiple hard links.)
1965
1966Enhance debugfs's "hash" command so the hash seed can be specified via
1967a command-line option.  In addition, allow the hash algorithm to be
1968specified by name instead of just by number.
1969
1970Fix e2fsck so that we don't accidentally print the translation file's
1971header when asking the user a custom question so there is no prompt
1972defined for a particular problem record.  For example, the question
1973"Run journal anyway" will get the PO header tacked on because e2fsck
1974erroneously passed the null string to _().  (Addresses Launchpad Bug:
1975#246892)
1976
1977Enhance badblocks so that it can test a normal file which is greater
1978than 2GB.
1979
1980Enhance the badblocks command so that it displays the time and
1981percentage complete when in verbose mode.  (Addresses Debian Bug:
1982#429739)
1983
1984Fix a potential memory leak in a error handling path in debugfs's
1985ncheck function.
1986
1987Fix a potential memory corruption problem if a memory allocation fails
1988in resize2fs.
1989
1990Fix the usage message for debugfs's logdump command to be consistent
1991with its man manpage.
1992
1993Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
1994and Sweedish translation from the Translation Project.
1995

2005Programmer's Notes
2006------------------
2007
2008Fix a potential file descriptor leack in libcom_err by setting the
2009close-on-exec flag for a fd used for debugging.  (Addresses Red Hat
2010Bugzilla #464689)
2011
2012Fix a potential race in libcom_err by using sem_post/sem_init.  SuSE
2013has been carrying a patch for a long time to prevent a largely
2014theoretical race condition if a multi-threaded application adds and
2015removes error tables in multiple threads.  Unfortunately SuSE's
2016approach breaks compatibility by forcing applications to link and
2017compile with the -pthread option; using pthread mutexes has
2018historically been problematic.  We fix this by using sem_post/sem_init
2019instead.
2020
2021Fix e2fsprogs-libs build failure due to 'subs' target.  (Addresses
2022Sourceforge Bug: #2087502)
2023
2024Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
2025libraries when using ELF shared libraries.
2026
2027Fix ELF shared library when building on systems that don't already
2028have the e2fsprogs shared libraries already installed.  (Addresses
2029Sourceforge Bug: #2088537)
2030
2031Fix the pkg-config files so they work correctly when linking with
2032static libraries and fix the include directory so programs don't have
2033to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
2034instead.  (Addresses Sourceforge Bug: #2089537)
2035    
2036Make sure ext2fs_swab64() is compiled for all platforms, and not just
2037for x86.  (Addresses Debian Bug: #497515)
2038    
2039Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
2040non-x86 platforms.  (They had been removed for x86 earlier.)
2041
2042Fix diet libc compilation support, which had bitrotted due to lack of
2043TLC.  Fixing this improves general portability.
2044
2045When installing the link library when using ELF shared libraries,
2046avoid using absolute pathnames if the link library and the shared
2047library are installed in the same directory.  (Addresses Sourceforge
2048Bug: #1782913)
2049
2050Fix gen-tarball so it will work even if the top-level directory has
2051been renamed to something other than "e2fsprogs".  Also make
2052gen-tarball print the size of the resulting tar.gz file.

2054
2055E2fsprogs 1.41.1 (September 1, 2008)
2056====================================
2057
2058Many people are forgetting to update their mke2fs.conf file, and this
2059causes ext3, ext4, and ext4dev filesystems won't get created with the
2060proper features enabled.  We address this in two ways.  First, mke2fs
2061will issue a warning if there is not definition for an ext3, ext4, or
2062ext4dev filesystem and the user is trying to create such a filesystem
2063type.  Secondly, when installing from a source build, "make install"
2064will provide basic configuration file handling for /etc/mke2fs.conf.
2065If it exists, and does not mention ext4dev, it will be moved aside to
2066/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
2067be installed.  If the existing /etc/mke2fs.conf file does mention
2068ext4dev, then "make install" will install official mke2fs.conf file as
2069/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
2070they should look to see if any changes need to be merged.
2071
2072The mke2fs program will now create the journal in the middle of the
2073filesystem, since this minimizes seek times on average for fsync-heavy
2074workloads.  In addition, mke2fs will now create journals using extents
2075for filesystems that support them.  This results in a more efficient
2076encoding for the journal since it eliminates the need for using
2077indirect blocks.
2078
2079The mke2fs program will avoid allocating an extra block to the
2080journal.  (Addresses Sourceforge Bug: #1483791)
2081
2082Mke2fs will correctly enforce the prohibition against features
2083(specifically read-only features) in revision 0 filesystems.  (Thanks
2084to Benno Schulenberg for noticing this problem.)
2085
2086Mke2fs previously would occasionaly create some slightly non-optimally
2087placed inode tables; this bug has been fixed.
2088
2089The mke2fs and tune2fs programs now print the correct usage message
2090describing the maximum journal size.  (Addresses Debian Bug: #491620)
2091
2092Add support for setting the default hash algorithm used in b-tree
2093directories in tune2fs (from a command-line option) or mke2fs (via
2094mke2fs.conf).  In addition, change the default hash algorithm to
2095half_md4, since it is faster and better.
2096
2097The blkid library will now recognize MacOS hfsx filesystems, and
2098correctly extract the label and uuid for hfs, hfsx, and hfsplus
2099filesystems.  (Addresses Sourceforge Feature Requests: #2060292)
2100
2101The blkid library has improved detection of JFS and HPFS filesystems.
2102(Addresses Launchpad Bug: #255255)
2103
2104The blkid library is now much more efficiently handling devicemapper
2105devices, mainly by no longer using the devicemapper library.  This can
2106speed up access for systems with a large number of device mapper
2107devices.
2108
2109Blkid had a number of cache validation bugs in libblkid that have been
2110fixed.   (Addresses Debian Bug: #493216)
2111
2112Resize2fs will now properly close out the "updating inode references"
2113progress bar so there is a newline printed before printing the final
2114"resize is successful" message.
2115
2116Resize2fs will now correctly handle filesystems with extents and/o
2117uninitialized block groups correctly when file/directory blocks need
2118to relocated (i.e., when shrinking a filesystem or if the resize_inode
2119is not present).  To support this, the ext2fs library now supports
2120initializing inode and block bitmaps that are not yet initialized when
2121allocating them using ext2fs_new_block() and ext2fs_new_inode().  In
2122addition, e2fs_block_iterate2() can now support changing the location
2123of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
2124been optimized to avoid creating unnecessary new extents when updating
2125the location of blocks in the extent tree.  This will also help out
2126e2fsck's recovery of obscurely corrupted filesystems with extents,
2127when blocks are claimed by multiple inodes.
2128
2129Add support for on-line resizing ext4 filesystem with the flex_bg
2130filesystem feature.  The method for doing so is not optimal, but to do
2131a better job will require kernel support.
2132
2133E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
2134debugfs programs to not be able to read e2image files; the signed
2135vs. unsigned bug in the code which read bitmaps from the e2image has
2136been fixed.   (Addresses Debian Bug: #495830)
2137
2138Resize2fs is now correctly managing the directory in-use counts when
2139shrinking filesystems and directory inodes needed to be moved from one
2140block group to another.  This bug has been around since e2fsprogs
21411.26, and is largely harmless, but does cause a filesystem corruption
2142which will be flagged by e2fsck after the filesystem has been shrunk.
2143 
2144E2fsck will no longer issue spurious complaints about the inode size
2145caused by very large extent-based files, and by blocks reallocated
2146using fallocate() with the FALLOC_FL_KEEP_SIZE option.  (Addresses
2147Kernel Bugzilla: #11341)
2148
2149Mke2fs will now set the creation timestamp on the lost+found directory
2150and the root directory.  (More generally, all new inodes created using
2151the ext2fs library will correctly set the creation timestamp.)
2152
2153E2fsck now correctly calculates ind/dind/tind statistics in the
2154presence of extent-based files.  In addition, "e2fsck -v" will report
2155statistics of the depth of extent trees in the filesystem.  E2fsck can
2156also give an inode fragmentation report using "e2fsck -E fragcheck"
2157which can be useful when debugging the kernel block allocation
2158routines.
2159
2160Fix support for empty directory blocks in ext4 filesystems with 64k
2161blocksize filesystems.
2162
2163E2fsck will now print the depth of corrupt htree directories.
2164
2165Debugfs's htree command now correctly understands extent-based
2166directories.  It will also print out the minor hash as well as the
2167major hash.
2168
2169Debugfs has a new command which will print the supported features of
2170e2fsprogs, to enable scripts to know whether the installed version of
2171e2fsprogs can support a specific feature.
2172
2173Debugfs will now write files using extents for filesystems that
2174support them.
2175
2176The error message printed by "tune2fs -I" if the inode size was too
2177small was rather confusing, so it has been improved.  Also, we won't
2178try to create an undo log until we know that command-line-specified
2179parameters such as "tune2fs -I <inode size>" are valid.
2180
2181Given some filesystems found "in the wild" that had non-zero block
2182group checksums even though the uninit_bg/gdt_sum feature was not
2183enabled, e2fsck would issue spurious error messages.  Teach
2184ext2fs_group_desc_csum_verify() to ignore the block group checksum
2185entirely if the feature flag is not set.  (Addresses Debian Bug:
2186#490637)
2187
2188The blkid program will now print out a user-friendly listing of all of
2189the block devices in the system and what they contain when given the
2190-L option.  (Addresses Debian Bug: #490527)
2191
2192The filefrag program now has a more accurate calculation for the
2193number of ideal extents.  (Addresses Debian Bug: #458306)
2194
2195The test I/O manager is now enabled by default, but its overhead is
2196only incurred when it would be enabled via the TEST_IO_FLAGS or
2197TEST_IO_BLOCK environment variables.
2198
2199Typographical errors in various program strings and usage messages
2200have been fixed; most of these were pointed out by the e2fsprogs
2201message catalog translators.  (Thanks, translators!)
2202
2203Update and clarified various man pages, as well as some typographical
2204errors in the libext2fs texinfo file.
2205
2206Fixed various Debian packaging issues --- see debian/changelog for
2207details.
2208
2209Add Indonesian and update French, Polish, Dutch, German, Sweedish,
2210Czech, and Vietnamese Translations.  (Addresses Debian Bugs: #313697,
2211#401092)
2212
2213Programmer's Notes
2214------------------
2215
2216Fix portability problem with the badblocks group; for systems that
2217don't have nanosleep(), try using usleep() instead.
2218
2219The "make check" target in the e2fsck directory now sets
2220LD_LIBRARY_PATH before running the various e2fsck internal library
2221regression tests.
2222
2223The crc32 regression test in the e2fsck library is now portable to
2224greater varienty of environments, including big-endian systems and
2225when cross-building e2fsprogs for embedded systems.  (Addresses
2226Sourceforge Bug: #2019287)
2227
2228The ext2fs_extent_set_bmap() had some bugs when setting the first
2229block in a file, or when replacing a single block extent.  Those cases
2230fortunately were came up relatively rarely when e2fsck was checking
2231files, but caused some problems when resize2fs was shrinking
2232extent-based files.
2233
2234Fix a potential core-dumping bug in libe2p's iterate_on_dir()
2235function.
2236
2237Various ext2fs library functions --- ext2fs_block_iterate2(),
2238ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
2239allocated memory to avoid memory leaks in all of their error return
2240paths.
2241
2242Ext2ed was failing to build because masix support had been removed in
2243the rest of e2fsprogs, so ext2ed no longer has masix support, either.
2244
2245The configure script now respects the LDFLAGS environment variable if
2246it is set when configure is called.  (Addresses Sourceforge Feature
2247Request: #1937287)
2248
2249Libuuid is now more portable to the Windows platform.  (Addresses
2250Sourceforge Feature Request: #1937287)
2251
2252The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2253bare echo commands so that configure flags such as --quiet work
2254correctly.  (Addresses Sourceforge Patches: #2058794)
2255
2256A few uses of sprintf have been removed from the ext2fs library to
2257make life easier for bootloaders with a limited libc environment.
2258(Addresses Sourceforge Bug: #2049120)
2259
2260The ext2fs_read_inode() checks the validity of the inode number passed
2261to it earlier, to avoid doing some needless work when it would fail
2262anyway.
2263
2264The ext2fs_open() checks the validity of the blocksize parameter
2265passed to it earlier, to avoid doing some needless work when it would
2266fail anyway.
2267
2268Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2269top-level Makefile.  That automatic rule is used to better support
2270SCCS, but it caused problems for a particular niche distribution which
2271likes to use configure.sh files to store the configure options used to
2272build a package.  Unfortuntaely GNU make will use the configure.sh to
2273replace the configure script, resulting in a self-inflicted fork bomb
2274leading to an out-of-memory crash.
2275
2276To support old GNU C compilers don't use C99/C++ comments, but only
2277K&R style comments, and don't try to use __builtin_expect if __GNUC__
2278is less than 3.  (__builtin_expect is only supported for gcc versions
22792.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2280this is an optimization, we only try to use __builtin_expect for gcc 3
2281and up.)
2282
2283In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2284__LITTLE_ENDIAN, which are only defined by glibc's header files and
2285hence isn't portable.
2286
2287For the convenience for some distributions that need a static tune2fs,
2288the Makefile for misc/ now has a tune2fs.static target.
2289
2290The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2291for extent-based files
2292
2293The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2294files.
2295
2296All source files no longer have any trailing white space.
2297
2298The io_channel_read_blk64() and io_channel_write_blk64() functions are
2299now functions instead of C preprocessor macros to provide better
2300forward compatibility.
2301
2302The e2fpsrogs translation template now expands the @x abbrevation.
2303
2304Various namespace leackages in libblkid, libe2p, and libext2fs have
2305been fixed.
2306
2307Fix a parallel build problem in e2fsprogs.
2308
2309E2fsprogs is now more portable to Solaris.
2310  * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
2311    are always present.
2312  * Scripts do not assume that /bin/true is always in /bin
2313  * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2314  * Flush stdio handles before calling setbuf(), since Solaris will
2315    discard any pending output to the stream.
2316  * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2317    picky about which C compiler can beused for SUSv3 conformance.
2318    Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2319    and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2320    Since we need some SUSv3 functions, consistently use SUSv3 so
2321    that e2fsprogs will build on Solaris using c99.
2322  * Solaris C99 does not support varargs C preprocessor macros
2323  * Solaris header files pollute the C namespace if in/netinet.h
2324    is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2325    typedef.
2326  * Solaris ships with a pathetically ancient shell in /bin/sh so we
2327    avoid the use of various more avanced shell constructs such as $().
2328
2329The "make rpm" command will now take some extra configure optiosn from
2330the build environment without needing to patch the source tree.
2331
2332The ext2fs_add_dir_block() function will now grow the dblist more
2333aggressively as an optimization to avoid copying the array too often.
2334
2335The e2fsck_write_bitmaps() will write the block and inode bitmaps
2336together instead of in two passes.
2337
2338
2339E2fsprogs 1.41 (July 10, 2008)
2340==============================
2341
2342Add support for ext4 filesystem features, in particular extents,
2343uninit_bg, flex_bg, huge_file, and dir_nlink features.  Also add
2344support for checking journal checksums.  Debugfs will print new
2345superblock and inode fields that were defined for ext4.  For example,
2346the nanosecond and i_version fields of an inode, and the
2347s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2348Note: Resize2fs doesn't currently support the combination of flex_bg
2349and !resize_inode.  (Addresses Debian Bug: #388452, #425477)
2350
2351Tune2fs can support migrating a filesystem from using 128 byte inodes
2352to 256 byte inodes, so it can take advantage of the full features of
2353ext4.
2354
2355Add support for "undo" support.  E2fsck and mke2fs can optionally
2356record an undo log which can replayed by the program e2undo.
2357
2358E2fsck could damage a filesystem by trying to relocate inode tables
2359due to corrupted block group descriptors, where the attempted inode
2360table relocation would do far more harm than good.  E2fsck has been
2361fixed to detect this these sorts of corrupted block group descriptors
2362much earlier in e2fsck processing, so it can try to use the backup
2363superblock and block group descriptors first.  This should be a much
2364better strategy for recovering these types of corrupted filesystems.
2365(Addresses Sourceforge Bug: #1840291)
2366
2367E2fsck will display a more understandable message when the last check
2368field in the superblock is in the future.  (Addresses Debian Bug:
2369#446005).
2370
2371E2fsck now performs more extensive and careful checks of extended
2372attributes stored in the inode.
2373
2374Enhance mke2fs to print a more explanatory error message when
2375ext2fs_get_device_size() returns EFBIG.  (Addresses Debian Bug:
2376#488663)
2377
2378Fix mke2fs to use a default block size of 4k when formatting an
2379external journal device.  This is done by using a fixed filesystem
2380type list that consists only of the single filesystem type "journal"
2381when looking up configuration keys in /etc/mke2fs.conf.  (Addresses
2382Debian Bug: #488663)
2383
2384Speed up how mke2fs writes the journal data blocks by writing the disk
2385blocks in larger chunks.
2386
2387Fix blkid handling of stale devices.  Fix a bug which could cause a
2388core dump while garbage collecting the blkid cache, and assure that
2389blkid_find_dev_with_tag() never returns a non-existent device.  Also,
2390if a filesystem is found at a new /dev location, eliminate any
2391duplicate stale entries which can not be verified.
2392(Addresses Debian Bugs: #487758, #487783)
2393    
2394Add more paranoid checks for LVM volumes and swap partitions in
2395blkid's probe function, to reduce the chances of false positives.
2396
2397The mke2fs program now has a much more sophisticated system for
2398controlling configuration parameters of a newly created filesystem
2399based on a split filesystem and usage type system.  The -t option to
2400mke2fs was a deprecated alias to -c; it now specifies a filesystem
2401type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2402separated usage list.  The filesystem type information and type
2403information is used to extract configuration parameters from the
2404/etc/mke2fs.conf file.
2405
2406The mke2fs program will no longer complain and request the -f option
2407when the user tries to create a filesystem with greater than 2**31
2408blocks.
2409
2410When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2411adjust the mke2fs.conf file so filesystems for the Hurd are created
2412with a blocksize of 4096 and inode size of 128, which is all it knows
2413how to handle.  (Addresses Debian Bug: #471977)
2414    
2415Mke2fs will always make sure that lost+found always has at least 2
2416blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2417
2418Resize2fs will now print the minimum needed filesystem size if given
2419the -P option, and will resize the filesystem to the smallest possible
2420size if given the -M option.
2421
2422Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2423blocks are consumed during an off-line resize.
2424
2425The "ls" command in debugfs now supports the -p option, which causes
2426it to quote the filenames so that spaces or tabs in directory entries
2427are easily visible.  (Addresses Red Hat Bugzilla: #149480; Addresses
2428Sourceforge Feature Request: #1201667)
2429
2430Fix a potential off-by-one buffer oveflow in the fs_device_name in an
2431e2image file.
2432
2433The chattr program will return a non-zero exit code in case of
2434failures, and error messages can be suppressed with the -f option.
2435(Addresses Red Hat Bugzilla: #180596)
2436
2437Fix a bug in badblocks which caused it to overrun an array and likely
2438crash if more than 8 test patterns are specified using the -t option.
2439(Addresses Debian Bug: #487298)
2440    
2441Add support to badblocks to limit how quickly it reads from the disk
2442drive (so it can be used for background scrubbing), and so it will
2443abort after finding a given number of errors.
2444
2445Remove support for the legacy big-endian filesystem format which only
2446existed on extremely long-dead PowerPC kernels almost a decade ago.

2465bitmaps.
2466
2467Fix gcc -Wall warnings
2468
2469Fix the pkg-config files so that private librares are specified in
2470"Libs.private:".
2471
2472Fix the libext2fs.texinfo manual so it builds with modern versions of
2473texinfo.
2474

2478
2479Avoid using predictable filenames in /tmp in blkid's regression test
2480suite.  Also remove bashism's in the regression test script.
2481
2482If the configure script is given --with-diet-libc, don't use thread
2483local storage, since diet libc doesn't support TLS.  (Addresses
2484Sourceforge Bug: #2000654)
2485    
2486Fix the blkid regression test suite to tolerate older versions of
2487mkswap that don't support the -U option.
2488
2489A few library routines have been converted to support 64-bit block
2490numbers; in particular, the I/O manager functions, the test_io,
2491inode_io, and unix_io managers have all be converted to support 64-bit
2492operation.
2493
2494Debugfs can now be extended for use by test programs.  See
2495lib/ext2fs/extents.c for an example for how it can be used.  The test
2496program links against the debugfs object files, and provides
2497additional commands by defining an auxiliary libss command table.
2498
2499The lazy_bg filesystem feature, which was only used by developer's
2500testing, has been removed since it has been largely supplanted by
2501uninit_bg.  This also simplifies the code.

2532E2fsprogs 1.40.10 (May 21, 2008)
2533================================
2534
2535When deciding whether or not to revalidate a blkid cache entry, if the
2536device's mtime is newer than the last time the cached entry was
2537validated, force a revalidation.
2538
2539Fix a potential data corruption bug in e2fsck in the journal replay.
2540The chances of this is happening is extremely remote, especially the
2541default data=ordered or data=writeback modes.  However, if a block
2542which has been journalled starts with the first four bytes 0xc03b3998,
2543when e2fsck replays the journal, those four bytes will be replaced
2544with zero's.  Fortunately, it is highly, highly unlikely for e2fsck
2545metadata to begin with those fatal 4 byte sequence, and unless
2546data=ordered mode is in use, data blocks are never journaled.

2560E2fsprogs 1.40.9 (April 27, 2008)
2561=================================
2562
2563SuSE's security team audited uuidd and came up with a few minor
2564issues.  None of them are serious given that uuidd runs setuid as a
2565unprivileged user which has no special access other than libuuid
2566directory, but it's good to get them fixed.
2567
2568One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
2569work correctly with in-inode extended attributes.
2570
2571Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
2572translations.
2573
2574Debugfs will avoid using a pager if the standard output is not a tty.
2575
2576Fix debugfs and tune2fs to correctly handle daylight savings time when
2577parsing a time string.
2578
2579Fixed spelling mistakes, typos, and otherwise clarified man pages.
2580
2581Fix fsck completion bars when multiple filesystems were being checked
2582in parallel.  (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
2583#203323, Addresses Sourceforge Bug: #1926023)
2584
2585Fix fsck so that progress information is sent back correctly when
2586multiple filesystems are being check and the output of fsck is being
2587redirected to a file descriptor.  Also, include the device name (w/o
2588spaces) in the progress information sent back via a file descriptor.
2589(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
2590#1926023)
2591
2592Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
2593
2594If logsave receives a SIGTERM or SIGINT signal, it will now pass that
2595signal to its child process.
2596
2597Fix mke2fs's creation of are resize inode when there is a non-standard
2598s_first_data_block setting.
2599
2600Fix bug in blkid when run by an unprivileged user; most devices were
2601not reported correctly.  9Addresses Launchpad Bug: #220275)
2602
2603Mke2fs will not allow the logically incorect combination of
2604resize_inode and meta_bg, which had previously caused mke2fs to create
2605a corrupt fileystem.

2629
2630E2fsprogs 1.40.8 (March 13, 2008)
2631=================================
2632
2633Fixed e2image -I so it works on image files which are larger than 2GB.
2634
2635Fixed e2fsck's handling of directory inodes with a corrupt size field.  If
2636the size is larger than the number of blocks found in the inode, don't
2637try to allocate extra empty blocks at the end of the directory to make
2638up the difference; there's no point to doing that.  In addition, if
2639the size is not a multiple of a blocksize, always fix it.
2640
2641E2fsck handled a pass 2 "should never happen error" by not giving
2642enough information and then core dumping.  Unfortunately, it was all
2643too easy to trigger the "should never happen" situation if a
2644directory's inode size was not correct.  This has been fixed, but
2645e2fsck has also been taught how to handle this situation more
2646gracefully, by simply removing the inode hash tree information, so
2647that it can be rebuilt again after e2fsck's pass 3.  (Addresses
2648Launchpad Bug: #129395)
2649
2650Resize2fs had a bug resizing large inodes with extended attributes
2651that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2652completely on big-endian systems such as PowerPC.  The bug should be
2653completely fixed now.  Yay for regression test suites.  (Addresses Red
2654Hat Bugzilla: #434893)
2655    
2656Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
2657translations.  Many thanks to Philipp Thomas from Novell for stepping
2658up to become the new German translation maintainer!  (Addresses Debian
2659Bugs: #302512, #370247, #401092, #412882).
2660
2661When e2fsck is clearing a corrupt inode's HTREE directory information,
2662make it clear that it is just clearing the HTREE information, not the
2663entire inode.
2664
2665Fixed spelling mistakes, typos, and otherwise clarified man pages.  
2666
2667Programmer's notes
2668------------------
2669
2670Add new functions, ext2fs_dblist_get_last() and
2671ext2fs_dblist_drop_last(), which allows the caller to examine the last
2672directory block entry added to the list, and to drop if it necessary.
2673
2674Fixed a portability problem in libblkid with DJGPP.
2675
2676Fix an obvious typo in an "internal error" message in e2fsck.  Thanks
2677to Philipp Thomas for pointing this out.
2678
2679If the info files are not built, change "make install" so it doesn't
2680fail with an error code.

2682
2683E2fsprogs 1.40.7 (February 28, 2008)
2684====================================
2685
2686Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2687depreciate the -s option, since it can result in filesystems which
2688e2fsck can't fix easily.  There are very good reasons for wanting to
2689disable sparse_super; users who wants to turn off sparse_super can use
2690debugfs.  (Addresses Sourceforge Bug: #1840286)
2691    
2692Add missing options to mke2fs's usage message.  (Addresses Sourceforge
2693Bug: #1751393)
2694    
2695Fix bug in resize2fs when large (greater than 128 byte) inodes are
2696moved when a filesystem is shrunk; it was only moving the first 128
2697bytes, so extended attributes were not getting moved.  (Addresses Red
2698Hat Bugzilla: #434893)
2699
2700E2fsck now prints an explicit message when the bad block inode is
2701updated, to avoid confusion about why the filesystem was modified.
2702(Addresses Sourceforge Bug: #756460)
2703    
2704Allow mke2fs and tune2fs manipulate the large_file feature.
2705Previously we just let the kernel and e2fsck do this automatically,
2706but e2fsck will no longer automatically clear the large_file feature.
2707It still isn't really necessary to worry about this feature flag
2708explicitly, but some users seem to care.  (Addresses Red Hat Bugzilla:
2709#258381)
2710    
2711Suppress message about an old-style fstab if the fstab file is empty.
2712(Addresses Debian Bug: #468176)
2713    
2714Fix (really minor) bug in debugfs's find_free_block so it avoids
2715reporting a free block more than once if there are too few free blocks
2716in the filesystem.  (Addresses Sourceforge Bug: #1096315)
2717    
2718Change e2fsck to no longer clear the LARGE_FILES feature flag
2719automatically, when there are no more > 2GB files in the filesystem.
2720It's been almost a decade since there have been kernels that don't
2721support this flag, and e2fsck clears it quietly without telling the
2722user why the filesystem has been changed.
2723    
2724Fix bug which could cause libblkid to seg fault if a device mapper
2725volume disappears while it is being probed.  (Addresses RedHat
2726Bugzilla: #433857)
2727    
2728Inhance e2fsck's reporting of unsupported filesystem feature flags.
2729(Addresses Sourceforge Feature Request: #1175808)
2730    
2731Fix option syntax in dumpe2fs for explicit superblock and blocksize
2732parameters.  What was currently documented in the man page has been
2733broken for some time, due to getopt() implementation changes.  The
2734option sytax has been changed to one which is can be more portable
2735supported and which is consistent with the format for extended options
2736in mke2fs and tune2fs.  (Addresses Sourceforge Bug: #1830994)
2737    
2738Add support to tune2fs to clear the resize_inode feature.  This
2739requires an fsck afterwards.  (Addresses Red Hat Bugzilla: #167816)
2740
2741Teach blkid to detect LVM2 physical volumes.  (Addresses Red Hat
2742Bugzilla: #409321)

2747Add support for setting new superblock fields to debugfs's
2748set_super_value.
2749
2750Add support for printing "mostly-printable" extended attributes in
2751Debugfs.
2752

2774partially filled-in filesystem object on an error, so that e2fsck can
2775print more intelligent error messages.
2776    
2777Add a new function e2p_edit_feature2() which allows the caller to
2778specify which feature flags are OK to set or clear, and which returns
2779more specific information about feature flags which are not allowed to
2780be set/cleared.

2843===================================
2844
2845Fix a potential overflow big in e2image if the device name is too
2846long.
2847
2848Mke2fs will now create new filesystems with 256 byte inodes and the
2849ext_attr feature flag by default.  This allows for much better future
2850compatibity with ext4 and speeds up extended attributes even on ext3
2851filesystems.
2852
2853Teach e2fsck to ignore certain "safe" filesystem features which are
2854set automatically by the kernel.  Having the kernel set features
2855automagically behind the user's back is a bad idea, and we should try
2856to break the kernel of this habit, especially for the newer ext4
2857feature flags.  But for now, we will try to avoid needless full checks
2858which can annoy users who are doing fresh installs.
2859
2860Add support in tune2fs and mke2fs for making a filesystem as being "ok
2861to be used with test kernel code".  This will be needed for using test
2862filesystems with the latest ext4 kernel code.

2932====================================
2933
2934Improve time-based UUID generation.  A new daemon uuidd, is started
2935automatically by libuuid if necessary.  This daemon is setuid to allow
2936updates to /var/lib/libuuid, so the clock sequence number can be
2937stored and so if the clock is set backwards, it can be detected.
2938(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
2939#233471)
2940
2941Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2942superblocks.  This avoids e2fsck from concluding that a full
2943filesystem check is required before backing up the superblock due to
2944changes in the feature flags.  (Addresses Debian Bug: #454926)
2945
2946Fix fsck to only treat the '#' character as a comment at the beginning
2947of the line in /etc/fstab.  Otherwise fstabs for the fuse filesystem
2948will cause fsck to issue an bogus warning message.

2953with garbage labels from sending escape sequences to the user's screen
2954that might, for example place it in graphics mode.  (Addresses Ubuntu

2986E2fsprogs 1.40.3 (December 5, 2007)
2987===================================
2988
2989Fix a potential security vulnerability where an untrusted filesystem
2990can be corrupted in such a way that a program using libext2fs will
2991allocate a buffer which is far too small.  This can lead to either a
2992crash or potentially a heap-based buffer overflow crash.  No known
2993exploits exist, but main concern is where an untrusted user who
2994possesses privileged access in a guest Xen environment could corrupt a
2995filesystem which is then accessed by the pygrub program, running as
2996root in the dom0 host environment, thus allowing the untrusted user to
2997gain privileged access in the host OS.  Thanks to the McAfee AVERT
2998Research group for reporting this issue.  (Addresses CVE-2007-5497.)
2999
3000Fix hueristics in blkid which could cause a disk without partitions to
3001be incorrectly skipped when a loopback device is present.  (Addresses
3002Red Hat Bugzilla #400321.)
3003
3004Fix e2image so that in raw mode it does not create an image file which
3005is one byte too large.
3006
3007Change mke2fs's usage message so it recommends the preferred -E option
3008instead of the deprecated -R option.
3009
3010Enhance the blkid library so it will recognize squashfs filesystems.
3011(Addresses Red Hat Bugzilla #305151.)
3012
3013Enhance e2fsck so it will force the backup superblocks to be backed up
3014if the filesystem is consistent and key constants have been changed
3015(i.e., by an on-line resize) or by e2fsck in the course of its
3016operations.
3017
3018Enhance blkid's detection of FAT filesystems; so that USB disks with
3019only a single bootable partition will not get missed.
3020
3021E2fsck will no longer mark a filesystem as invalid if it has time
3022errors (i.e., if superblock mount time or last write time is in the
3023future) and the user refuses to fix the problem.
3024
3025The Ubuntu init scripts don't properly set the system time correctly
3026from hardware clock if the hardware clock is configured to tick local
3027time instead of GMT time.  Work around this as best as we can by
3028providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
3029be set on Ubuntu systems.  (Addresses Debian Bug #441093, and Ubuntu
3030Bug #131201.)
3031
3032Fix fsck to ignore /etc/fstab entries for bind mounts.  (Addresses Red
3033Hat Bugzilla #151533.)
3034
3035Fix e2fsck so that if the superblock is corrupt, but still looks
3036vaguely like an ext2/3/4 superblock, that it automatically tries to
3037fall back to the backup superblock, instead of failing with a hard
3038error.
3039
3040Make the e2fsprogs program more robust so that they will not crash
3041when opening a corrupt filesystem where s_inode_size is zero.
3042
3043Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
3044arguments are detected as such and the parse error is reported to the
3045user.   (Addresses Debian Bug #435381.)
3046
3047Change e2fsck so it will not complain if a file has blocks reallocated
3048up to the next multiple of a system's page size.
3049
3050Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
3051about (valid) filesystems where the inode table extends to the last
3052block of the block group.  (Addresses Red Hat Bugzilla #214765.)
3053
3054Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
3055allocating inode tables for some relatively rare odd disk sizes.
3056(Addresses Red Hat Bugzilla #241767.)
3057
3058Add Catalan translation and update Dutch and Swedish translations
3059from the Translation Project.
3060
3061Fix big-endian byte-swapping bug in ext2fs_swap_inode_full().  We
3062still had an issue when trying to figure out whether we need to
3063byte-swap fast symlinks that contained extended attributes.

3070-------------------
3071
3072Fix mke2fs tests to avoid needing any significant ^M (CR) characters
3073
3074Add "make check" to the RPM spec file
3075
3076Fix "make install" and 'make unstall" in misc/Makefile.in so that it
3077works correctly when the prefix is not the root directory.
3078
3079Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
3080clena up after themselves by deleting the test.img temporary file
3081after completing the test.
3082
3083Fixed a corner case bug ext2fs_unlink() when trying to delete the
3084first directory entry in a directory block and the last directory
3085entry in the previous directory block is not in use.  Fortunately
3086ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
3087places where it is extremely unlikely to run into this corner case.
3088
3089Fix missing dependency which would cuase parallel builds to fail.
3090(Addresses Sourceforge Bug #1842331.)
3091
3092Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
3093calling open(O_CREATE) with a missing mode parameter.
3094
3095Fix the test_ss.c in lib/ss so it can be used as an example
3096application program for the library as well as a regression test
3097suite.
3098
3099Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
3100are properly passed back up through the call stack.
3101
3102E2fsprogs 1.40.2 (July 12, 2007)
3103================================
3104
3105A recent change to e2fsck_add_dir_info() to use tdb files to check
3106filesystems with a very large number of filesystems had a typo which
3107caused us to resize the wrong data structure.  This would cause a
3108array overrun leading to malloc pointer corruptions and segfaults.
3109Since we normally can very accurately predict how big the the dirinfo
3110array needs to be, this bug only got triggered on very badly corrupted
3111filesystems.
3112
3113Fix a bug in e2fsck which caused it to incorrectly salvange
3114directories when the last entry's rec_len is bogusly too big.  This
3115resulted in a nonsense filesystem corruption to be reported, and
3116required a second run of e2fsck to fully fix up the directory.
3117
3118Update tune2fs man page to include more discussion of reserved blocks

3124
3125E2fsprogs 1.40.1 (July 7, 2007)
3126===============================
3127
3128Fix bug which could cause libblkid to loop forever.  When revalidating
3129a partition where there is obsolete information in /etc/blkid.tab, we
3130end up freeing a the type tag without clearing dev->bid_type, causing
3131blkid_verify() to loop forever.  (Addresses Debian Bug: #432052)
3132    
3133The Turkish translation has a bug in it where it has the translation
3134of "E@e '%Dn' in %p (%i)" to "E@E".  This causes @E to be expanded at
3135@E, recursively, forever, until the stack fills up and e2fsck core
3136dumps.  We fix this by making e2fsck stop @-expansions after a
3137recursive depth of 10, which is far more than we need.
3138(Addresses Sourceforge Bug: #1646081)
3139    
3140Compile the default mke2fs.conf into mke2fs program.  People are
3141getting surprised by mke2fs creating filesystems with different
3142defaults than earlier versions of mke2fs if mke2fs.conf is not
3143present.  So we now create a built in version of mke2fs.conf file
3144which is used by mke2fs if the /etc/mke2fs.conf is not present.
3145(Addresses SourceforgeBug: #1745818)
3146
3147Improve the config/parse_types.sh helper script.  Fix a potential
3148security problem if e2fsprogs is built as root (as Gentoo does!).  In
3149addition fix the script and how it is called from the configure script
3150so that it does the right thing when cross-compiling.  (Fixes Gentoo
3151bug: #146903)
3152    
3153Update Vietnamese, French, and Dutch PO files from the Translation
3154Project.  Also created a new e2fsprogs.pot file for translator.
3155    
3156Fix bogus strip permission errors when building under Debian.  When
3157building the e2fsprogs dpkg's, the dh_strip command emits a large
3158number of error messages caused by the permissions not being right.
3159So run dh_fixperms before running dh_strip.
3160
3161Programmer's Notes:
3162-------------------
3163
3164Add new function: profile_set_default().  This function sets the value
3165of the pseudo file "<default>".  If the file "<default>" had
3166previously been passed to profile_init(), then def_string parameter
3167will be parsed and used as the profile information for the "<default>"
3168file.
3169    
3170Fix mk_cmds's error reporting so that it is unambiguous that it is the
3171mk_cmds script which is generating the error.  (Obviates Gentoo patch:
3172e2fsprogs-1.32-mk_cmds-cosmetic.patch)
3173    
3174Fix the test suite to use LC_ALL instead of LANG.  LC_ALL is the "high
3175priority" environment variable that overrides all others, where as
3176LANG is the lowest priorty environment variable.  If LC_ALL is set, it
3177doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3178the all the rest are set.  This will assure that the locale when
3179running the test suites is the "C" locale.  (Obviates Gentoo patch:
3180e2fsprogs-1.38-tests-locale.patch)
3181    
3182
3183E2fsprogs 1.40 (June 29, 2007)
3184==============================
3185
3186Fix divide by zero error in blkid's NTFS probing logic.
3187
3188Add new blkid -g option which causes the blkid cache to be garbage
3189collected.
3190
3191Fix a bug in libblkid which could cause the internal field bid_type to
3192become corrupted.  Fortunately bid_type isn't used much, and bid_label
3193and bid_uuid is only used by debugging code, so the impact of this bug
3194was very minor.
3195
3196Mke2fs will now store the RAID stride value when a filesystem is
3197created with a requested RAID stride, and then use it automatically in
3198resize2fs.
3199
3200Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3201isn't too big.  In some cases Lustre users have tried specifying an
3202inode size of 4096 bytes, while keeping an inode ratio of one inode
3203per 4096 bytes.  
3204
3205Improve sanity check in e2fsck's algorithm for finding a backup
3206superblock, so that it won't accidentally find a superblock that was
3207located in the journal, and then later reject it as being not a valid
3208backup superblock.
3209
3210Fix e2fsck get_size logic so that it will work with the Linux floppy
3211driver.  The Linux floppy driver is a bit different from the other
3212block device drivers, in that if the device has been opened with
3213O_EXCL, it disallows another open(), even if the second open() does
3214not have the O_EXCL flag.  (Addresses Debian Bug: #410569)
3215
3216Fix error checking of badblock's last-block and start-block arguments.
3217(Addresses Debian Bug: #416477)
3218
3219Fix e2fsck so that it doesn't overwrite the backup superblocks when
3220recovering a journal until the master superblock has been confirmed as
3221being sane.
3222
3223Change the blkid library to be much more paranoid about concluding
3224that a partition contains an NTFS filesystem, and fetch the UUID and
3225LABEL information from NTFS filesystems.  (Addresses Launchpad Bug:
3226#110138)
3227
3228Factor out the code which sets the default journal size and move it
3229into libext2fs.
3230
3231Enhance e2fsck so it will recreate the ext3 journal if the original
3232journal inode was cleared to due it being corrupt after finishing the
3233filesystem check.
3234
3235Fix e2fsck so that it updates the journal inode if it is corrupted and
3236the backup journal information from the superblock was successfully
3237used to recover the filesystem.
3238
3239Fix e2fsck so that it checks all of the blocks in the journal inode
3240for validity.  The original code only checked the direct blocks to
3241make sure the journal inode was sane.  Unfortunately, if some or all
3242of the indirect or doubly indirect blocks were corrupted, this would
3243not be caught.
3244
3245Add support in blkid to detect LUKS encrypted partitions.
3246
3247Add extra sanity checks for extended attributes in the case where the
3248size is zero but the offset is very large.
3249
3250Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3251and ext2fs_get_next_inode_full().
3252
3253Clarify the copyright licenses used by the various libraries in
3254the top-level COPYING  file (Red Hat Bugzilla: 166058)
3255
3256Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3257
3258Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3259
3260Remove check in e2fsck which requires EA's in inodes to be sorted;
3261they don't need to be sorted, and e2fsck was previously wrongly
3262clearing unsorted EA's stored in the inode structure.
3263
3264Allow mke2fs or tune2fs to create a substantially larger journal (up
3265to 10,240,000 blocks).
3266
3267Fix MD superblock detection, and make sure the correct UUID is
3268reported from the MD superblock.
3269
3270Fix a signed vs. unsigned bug in debugfs.
3271
3272Enhance debugfs's date parser so that it accepts integer values.
3273
3274Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3275file with multiply claimed blocks is hard linked. or not at all if the
3276root directory contains shared blocks
3277
3278Enhance debugfs so it can modify the block group descriptors using the
3279command set_block_group_descriptor.
3280
3281Improve e2fsck's reporting of I/O errors so it's clearer what it was
3282trying to do when an error happens
3283
3284Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3285symlinks that have extended attributes.  (Addresses Red Hat Bugzilla:

3301
3302Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3303field on the first pass.
3304
3305Fix e2fsck to set the file type of the '..' entry when connecting
3306a directory to lost+found.  (Addresses Lustre Bug: #11645)
3307
3308Enhance e2fsck to recover directories whose modes field were corrupted
3309to look like special files.  This is probably only useful in
3310artificial test cases, but it will be useful if we ever do the "inodes
3311in directory" idea for ext4.
3312
3313Allow debugfs to dump (and rdump) > 2GB files.  (Addresses Debian Bug:
3314#412614)
3315
3316Fix resize2fs parsing of size parameter (in sector units).  This was
3317actually a bug in libe2p's parse_num_blocks() function.  When handling
3318the 's' suffix, it was ignoring the blocksize information passed in
3319from the caller and always interpreting the number in terms of a 1k
3320blocksize.  (Addresses Debian Bug: #408298)
3321
3322There was a floating point precision error which could cause e2fsck to
3323loop forever on really big filesystems with a large inode count.
3324(Addresses Debian Bug: #411838)
3325
3326Fix memory leak in ext2fs_write_new_inode()
3327
3328Add support for using a scratch files directory to reduce e2fsck's
3329memory utilization on really big filesystems.  This uses the TDB
3330library.  See the [scratch_files] section of the e2fsck.conf man page

3340
3341Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3342ext2fs_open() , which allows application to open filesystes with features
3343which are currently only partially supported by e2fsprogs.
3344
3345Allow unix_io to support offsets greater than 2G (Addresses
3346SourceForge Bug: #1547922)
3347
3348Fixed overflow and signed/unsigned problems caused by the number of
3349blocks or inodes exceeding 2**31 or being close to 2**32-1.
3350
3351Add support for unsigned directory hash calculations with hints in the
3352superblock to fix cross-architectural portability for htree
3353directories with filenames where the high 8th bit is set.  (Addresses
3354Debian: #389772)
3355

3357filesystem or the kernel does not support on-line resizing.
3358(Addresses Debian Bug: #380548)
3359
3360Require mke2fs -F -F for really dangerous operations, since -F is
3361needed for less dangerous operations such as creating filesystems
3362images in regular files, or creating filesystems on whole block
3363devices.  These relatively innocuous usages should NOT be confused
3364with running mke2fs on an apparently-mounted or in-use filesystem.
3365
3366Allow the default inode size to be specified into the mke2fs.conf
3367file.
3368

3376(Addresses Debian Bug: #378335)
3377
3378Fix debugfs display bug us that bytes that have the high bit set are
3379displayed as "ec" instead of "ffffffec".
3380
3381Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3382
3383Device mapper scanning wasn't working in the blkid library because the
3384pathnames had an extra "/dev" when they were being probed.
3385
3386Add GFS/GFS2 support to the blkid library.
3387
3388Fix blkid support of empty FAT filesystem labels.
3389
3390Avoid recursing forever (or for a long time) when the blkid library
3391searches for a device and there are symlinks to directories in /dev.
3392
3393Avoid unaligned halfword access in blkid when accessing FAT
3394superblocks, as this will cause Sparc/Solaris systems to throw a
3395SIGBUS error.
3396
3397The latest devmapper libraries requires pthreads, add -lpthreads to
3398the static link libraries for e2fsck.static if devmapper is enabled.
3399(Addresses Debian bug: #388718)
3400
3401Improve the (non-installed, for experts only) findsuper program by
3402printing the uuid and label from the superblocks, as well as the
3403starting and ending offsets of the filesystem given the information in
3404the superblock.  Omit by default printing superblocks that are likely
3405found in located in an ext3 journal unless an explicit -j option is
3406given.
3407
3408Updated Spanish, French and Dutch translations and added Catalan
3409translation.  (Addresses Debian bug: #411562)
3410
3411Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3412determining a partition's size, since binary searching to determine
3413the device doesn't work on FreeBSD.
3414
3415Documentation about UUID's is available in enough places, and it's
3416awkward to deal with debian-legal's insanities.  So I'm caving in the
3417"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3418don't have do the dfsg tarball.  Also remove the rule that only tried
3419to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3420e2fsprogs exclusively from Debian.  (Addresses Debian Bug: #407107)
3421
3422Fix the info-dir line so that the menu name does not contain a .info
3423prefix.  First of all, it's ugly, secondly, it causes the install-info
3424command to fail to remove the com_err info file from the
3425/usr/share/info/dir file when the comerr-dev package is removed and
3426purged.  (Addresses Debian Bug: #401711)
3427
3428Fixed spelling mistakes, typos, and otherwise clarified man pages.
3429(Addresses Debian Bug: #369761, #373004, #379695)
3430
3431Fixed various Debian packaging issues --- see debian/changelog for
3432details.  (Addresses Debian Bugs #389554, #390664, #413208, #419605,
3433#408352, #415560, #399155)
3434
3435
3436Programmer's notes:
3437-------------------
3438
3439E2fsck now supports the %It expansion when printing a problem report.
3440It will print the type of the inode in the problem context.
3441
3442Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
3443(Addresses Sourceforge Bug: #1565561)
3444
3445Remove unused variables and other lint/gcc -Wall cleanups
3446
3447Add check to ext2fs_get_device_size() so it will return EFBIG for for
3448filesystems contained in regular files where the filesystem image size
3449is returned by stat64().
3450
3451Set local environment variables to C so mk_cmds and compile_et always
3452work.  (Addresses SourceForge Bug: #1532177)
3453
3454Added the 64-bit byte swapping function ext2fs_swab64().
3455
3456Added two new helper functions to prevent 2**31/2**32-1 overflow
3457problems: ext2fs_div_ceil() and e2p_percent().
3458
3459Create new ext2fs library inline functions ext2fs_group_first_block()
3460and ext2fs_group_last_block() in order to calculate the starting and
3461ending blocks in a block group.
3462
3463Create the generated files read-only to remind developers not to edit them.
3464
3465Add support for autoconf 2.60 (with backwards compatibility for older
3466versions of autoconf).
3467
3468Added an "make rpm" target to top-level Makefile
3469
3470Added various FreeBSD portability fixes.
3471
3472Exclude mercurial files from the RPM build tree to speed up copy/build.
3473
3474Use root_sysconfdir to define the locations of mke2fs.conf and
3475e2fsck.conf instead of using a hard-coded /etc pathname.
3476
3477Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3478
3479Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3480
3481If diff -u is supported, use it to report test failures.
3482
3483Updates/improvements to RPM spec file
3484
3485Add on-disk format definitions for the following new features:
3486EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3487EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3488EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3489
3490Add a new make target "checked-failed" in the tests directory which
3491reruns any failed tests
3492
3493Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3494
3495Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3496pointer dereferences, memory leaks, etc.  None were security-criticial
3497problems.
3498
3499Fix up usage and decrement error messages in the test_icount program
3500
3501Add debugging code to the com_err library; if the environment variable
3502COMERR_DEBUG is set to 1, print out debugging messages as error tables
3503are added and removed from the com_err library.  If the
3504COMERR_DEBUG_FILE environment variable is set (and the process is not
3505setuid) the debugging messages may be redirected to a file.
3506
3507Change all of the e2fsprogs programs to use the newer add_error_table()
3508and remove_error_table() interfaces instead of the much older
3509initialize_*_error_table() function.
3510
3511Add TDB support into the ext2fs library.  This allows us to have a
3512guaranteed library we can count on always being present so we can
3513store data in an on-disk database.
3514
3515Add support for using TDB to store the icount data, so we don't run out
3516of memory when checking really large filesystems.
3517
3518Change the regression test suite so that it skips empty test directories.
3519
3520Define the l_i_iversion field in ext2_inode.  The l_i_version field is
3521now defined from the old l_i_reserved1 field in the ext2 inode.  This
3522field will be used to store high 32 bits of the 64-bit inode version
3523number.
3524
3525Add Makefile production rule for e2fsprogs.spec in case it gets
3526deleted.
3527
3528Add new function profile_get_uint() to allow for a clean way to fetch
3529unsigned integers from the context.
3530
3531Add test to make sure the ext2 superblock structure is 1024 bytes.
3532
3533Fix typo in name of f_dup4 regression test
3534
3535Add new function blkid_gc_cache() which performs a garbage collection
3536pass on the /etc/blkid.tab file.
3537
3538The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY.  In
3539general, only e2fsck (after the filesystem is clean), tune2fs, and
3540resize2fs should change the backup superblocks by default.  Most
3541callers of ext2fs_open() should not be touching any superblock fields
3542which require the backups to be touched.
3543
3544Add new function to libext2fs, ext2fs_default_journal_size(), which
3545returns the default journal size.
3546
3547
3548E2fsprogs 1.39 (May 29, 2006) 
3549=============================
3550
3551Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3552between 2**31 and 2**32 blocks.
3553
3554Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3555configure the filesystem features, blocksize, and inode_ratio for
3556different filesystem types.
3557
3558Mke2fs will now create filesystems hash trees and on-line resizing
3559enabled by default, based on the new /etc/mke2fs.conf file.
3560
3561The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3562filesystem device node in exclusive mode to prevent accidents by
3563system administrators.  In the case of resize2fs and mke2fs, it will
3564only use exclusive mode if the filesystem is not mounted.
3565
3566Fixed a bug in mke2fs which caused it to to fail when creating the
3567resize inode for large filesystems.  (Addresses Debian Bug #346580)
3568
3569When allocating space for the RAID filesystems with the stride
3570parameter, mke2fs will now place each portion of the group's inode
3571table right up after the superblock (if present) in order to minimize
3572fragmentation of the freespace.
3573
3574Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3575efficiently by writing the inode and block bitmaps in one pass, thus
3576reducing the number of disk seeks required.
3577
3578Add support for on-line resizing to resize2fs.
3579
3580Fix blkid library so that logic to determine whether or not a device's
3581cached information in /etc/blkid.tab needs to be verified or not
3582doesn't get confused by a system clock which is insane (for example,
3583if the battery is dead on a Macintosh running PPC Linux.  (Addresses
3584Red Hat Bug: #182188)
3585
3586The blkid library will now store the UUID of the external journal used
3587by ext3 filesystems, so that in the future, the userspace mount binary
3588can use this to find the location of the external journal and pass
3589this information to the kernel.
3590
3591E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3592control how various options should be handled.  See the e2fsck.conf
3593man page for more details.   (Addresses Debian Bug: #150295)
3594
3595E2fsck now prints an explanatory message when delaying a filesystem
3596check when the system is running on battery.  (Addresses Debian Bug:
3597#350306)
3598
3599E2fsck will detect if the superblock's last mount field or last write
3600field is in the future, and offer to fix if so.  (Addresses Debian Bug
3601#327580) These problems will be fixed automatically in preen mode
3602since Debian's boot sequence bogusly doesn't set the time correctly
3603until potentially very late in the bootup process, and this can cause
3604false positives which will cause users' systems to fail to boot.
3605(Addresses Debian Bugs #343662 and #343645)
3606
3607E2fsck now checks to see if the superblock hint for the location of
3608the external journal is incorrect, and if so, offer to update it.
3609(Addresses Debian Bug: #355644)
3610
3611Fix e2fsck from segfaulting on disconnected inodes that contain one or
3612more extended attributes.  (Addresses Debian Bug: #316736, #318463)
3613
3614E2fsck will stop and print a warning if the user tries running a
3615read/write badblocks test on a read-only mounted root filesystem.
3616
3617Fix a memory leak in e2fsck's error paths.  (Thanks to Michael
3618C. Thompson for pointing these out; they were originally found using
3619Coverity.)
3620
3621When resizing a file containing a filesystem, resize2fs will expand or
3622truncate a file as necessary.  (Addresses Debian Bug: #271607)
3623
3624Resize2fs will now automatically determine the RAID stride parameter that
3625had been used to create the filesystem, and use that for newly created
3626block groups.   The RAID stride parameter may also be manually specified
3627on the command line using the new -S option to resize2fs.
3628
3629Fix mke2fs so that it correctly creates external journals on
3630big-endian machines (such as a S/390).  
3631
3632Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3633fail to print out the journal or hash seed UUID.  (Thanks to Guillaume
3634Chambraud for pointing this out.)
3635
3636Dumpe2fs will now print the size of the journal (if present).
3637
3638Fix debugfs's set_inode_field command so it can properly set the frag,
3639fsize, uid_high, gid_high, and author fields in the inode instead of
3640silently failing, and so that setting the i_size actually sets i_size
3641correctly.
3642
3643Add a new debugfs command, set_current_time, which sets fs->now so
3644that regression test suites can repeatedly modify the filesystem's
3645last_write fields.
3646
3647Fix a bug in debugfs's icheck which would incorrectly report the owner
3648of an extended attribute block.
3649
3650Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3651print a usage message when an illegal option character is given.
3652
3653Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3654so it won't core dump.  (Addresses SourceForge bug #1424311)
3655
3656Fix mklost+found so that it creates a full-sized directory on
3657filesystems with larger block sizes.
3658
3659Fix a file descriptor leak in blkid library.
3660
3661Fix a display bug in "badblocks -sv" so that the done message properly
3662clears the block number at the end of the test.  (Addresses Debian Bug
3663#322231)
3664
3665Allow fractional percentages to the -m option in mke2fs and tune2fs
3666(Addresses Debian Bug: #80205)
3667
3668Use fstat/fstat64 in getsize.c if the the target is a regular file,
3669instead of attempting to do a binary search.  Fix some fd leaks in
3670error cases.
3671
3672Add support for device mapper library to the blkid library to ensure
3673that the "best" (i.e., leaf) device is probed by the blkid library.
3674
3675Fix the blkid library so that it notices when an ext2 filesystem is
3676upgraded to ext3.
3677
3678Improve the blkid's library VFAT/FAT detection; it now understands
3679labels stored in the root directory, and is more paranoid about
3680checking the FAT superblock values.
3681
3682Fixed a fd leak in the uuid library which was causing problems for the
3683LVM tools.  (Addresses Debian Bug: #345832)
3684
3685Add support for the reiser4 and software suspend partitions to the
3686blkid library.  Also add support for extract the label from iso9660
3687filesystems.
3688
3689Fix a compile_et bug which miscount the number of error messages if
3690continuations are used in the .et file.
3691
3692Add extra sanity checks to protect users from unusual cirucmstances
3693where /etc/mtab may not be sane, by checking to see if the device is
3694reported busy (works on Linux 2.6) kernels.  (Addresses Debian Bug
3695#319002)
3696
3697Updated French, Dutch, Polish, and Swedish translations.  (Addresses Debian
3698Bug: #343149, #341911, #300871, #316604, #316782, #330789)
3699
3700Fix use-after-free bug in e2fsck when finishing up the use of the
3701e2fsck context structure.
3702
3703Fixed spelling mistakes, typos, and otherwise clarified man pages and
3704documentation.  (Addresses Debian Bugs: #329859, #322188, #316811,
3705#312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394,
3706#368179)
3707
3708Fixed various Debian packaging issues --- see debian/changelog for
3709details.  (Addresses Debian Bugs #317862, #320389, #290429, #310950,
3710#310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,
3711#362544, #362970)
3712
3713
3714Programmer's notes:
3715-------------------
3716
3717Update config.guess and config.sub to latest version (2006-02-23) from
3718FSF.
3719
3720Fix asm_types.h type conflicts on AMD 64 platforms.  (Addresses Debian
3721Bugs: #360661, #360317)
3722
3723Fixed the Makefile so that they work correctly on newer versions of
3724GNU make (i.e., 3.81).
3725
3726Add valgrind support to the regression test suites, and eliminate
3727false positives from valgrind.
3728
3729Add a regression test suite for the blkid library.
3730
3731Fix a fencepost error in resize2fs caught by valgrind.  
3732
3733Fix compiler warnings about missing memcpy prototypes.
3734
3735We no longer have the sparc assembly code in the header file any more,
3736so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc.  This would
3737break compiles on the sparc architectures when using gcc.
3738
3739In the libext2fs library, add the new field fs->now which if non-zero
3740is used instead of the system time when setting various filesystem
3741fields (last modified time, last write time, etc.)
3742
3743Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3744ext2fs.h which is needed since the inline functions use memcpy().
3745(Addresses Sourceforge Bug #1251062)
3746
3747Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3748the build system when building files in the util directory which are
3749needed during the build process.  This avoids potential problems when
3750cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3751are not recognized as valid by the host compiler.  (Addresses
3752Sourceforge Bug #1261547)
3753
3754Clean up the blkid library by making the superblock and generic i/o
3755functions to be more generic.  Clean up interface to the probe
3756function, and fix memory leak.  Finallly, remove an unneeded reference
3757to probe.h in the lib/blkid/resolve.c
3758
3759Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3760of invalid block #'s.
3761
3762The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3763indicate that the the function read/writes the memory location.
3764
3765Fix various gcc -Wall complaints.
3766
3767Add a dependency to make sure that the subdirectories are created
3768before creating all of the object files, in order to address parallel
3769build problem in the library Makefiles.  (Addresses Sourceforge Bug:
3770#1261553)
3771
3772Add $(LDFLAGS) to the command line argument when generating an ELF or
3773Solaris shared library, to allow cross-compile and other builds that
3774might need to specify -L paths to needed libraries.  (Addresses
3775Sourceforge Bug #1261549)
3776
3777Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3778intended for testing purposes.  It allows an ext2/ext3 developer to
3779create very large filesystems using sparse files where most of the
3780block groups are not initialized and so do not require much disk
3781space.  Eventually it could be used as a way of speeding up mke2fs and
3782e2fsck for large filesystem, but that would be best done by adding an
3783RO_COMPAT extension to the filesystem to allow the inode table to be
3784lazily initialized on a per-block basis, instead of being entirely
3785initialized or entirely unused on a per-blockgroup basis.
3786
3787Fix backwards compatibility so e2fsprogs will better compile on Linux
37882.0.35 systems.
3789
3790Make test scripts more robust against locale-related environment variables
3791
3792Fix type warning problem with sizeof() in ext2fs_open2().
3793
3794Fix type warning problem with time_t in debugfs.
3795
3796
3797E2fsprogs 1.38 (June 30, 2005)
3798==============================
3799
3800Fix blkid's test programs (built with "make check") compile correctly
3801even without "configure --enable-blkid-debug".
3802
3803Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3804type aliasing rules on newer gcc compilers.  (Addresses Red Hat
3805Bugzilla ##161183.)
3806
3807Fix com_err library to make it more compatible with recent changes
3808made to the com_err library in MIT Kerberos V5 version 1.4.
3809(Addresses Sourcefroge Bug #1150146)
3810
3811General cleanup of messages printed by e2fsprogs programs for grammar,
3812consistency, and to make life easier for translators.  Fixed a few
3813strings containing English that had not been marked as needing
3814translations.  Removed strings that do not need to be translated, to
3815make life easier for translators.
3816
3817Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3818test to see if a device appears to be in use instead of just relying
3819on /proc/mounts and /etc/mtab.  (Addresses Debian Bug #308594).
3820
3821Fix portability problem in the filefrag program affecting platforms
3822where the size of an integer is smaller than the size of a long.
3823(Addresses Debian Bug #309655)
3824
3825Mke2fs will now use a larger journal by default for filesystems
3826greater than 4GB.  (128 MB instead of 32MB).
3827
3828Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3829unless forced.  This is to avoid signed vs. unsigned kernel bugs in
3830block numbers that still need to be fixed.
3831
3832The blkid program has a new option which will more efficiently search
3833for device when it is known (or expected) that only one matching
3834device will be found in the system, such as when doing a lookup by
3835UUID.

3837Debian's e2fsprogs-specific initrd fragment will avoid including
3838unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3839and LD_LIBRARY_PATH, and filtering out libraries found in
3840/etc/ld.so.preload.  (Addresses Debian Bug: #304003)
3841
3842Fixed a potential portability issue in the blkid programs for
3843architectures where the char type is unsigned.  (Addresses Sourceforge
3844Bug: #1180585)
3845
3846Fix a bug in filefrag so that it doesn't falsely count an extra
3847discontinuity when the first block found is an indirect block.
3848(Addresses Debian Bug #307607).
3849
3850Fix blkid's recognition of cramfs filesystems, and enhance it to be
3851able to handle cramfs labels.
3852
3853Fix debugfs's stat command to not core dump when a filesystem is not
3854open.
3855
3856Fix e2fsck's handling of error conditions caused by the resize inode
3857claiming blocks that are also used by other inodes, a filesystem
3858corruption which was commonly caused by a bug in Fedora Core 3's
3859resize2fs program.
3860
3861Fixed bug in filefrag which caused it to fail on non-ext2/3
3862filesystems.  (Addresses Debian Bug: #303509)
3863
3864If the superblock last mount time indicates that the system clock may
3865not be accurate, then e2fsck will omit checking inodes' deletion time
3866field for indications of a potential corrupted orphaned inode list.
3867(Previously e2fsck only ommited these LOW_DTIME checks when the
3868superblock's last write time looked insane.)
3869
3870Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
3871(Addresses Debian bug #302200)
3872
3873Make the blkid library more paranoid about being run from setgid
3874programs, and to use __secure_getenv() from libc if it is available.
3875
3876Fixed spelling mistakes, typos, and otherwise clarified man pages.
3877(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
3878and Sourceforge Bug: #1189803)
3879
3880Updated and fixed translations.
3881
3882Fixed various Debian packaging issues --- see debian/changelog for
3883details.
3884
3885Programmer's notes:
3886-------------------
3887
3888Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3889changed to take an unsigned int for the bit number.  Negative bit
3890numbers were never allowed (and didn't make any sense), so this should
3891be a safe change.  This is needed to allow safe use of block numbers
3892greater than or equal to 2**31.
3893
3894The compile_et program will avoid recreating generated foo_err.c and
3895foo_err.h files if no changes are necessary.  The compile_et program
3896will also atomically replace these files to avoid a potential parallel
3897build race problem on SMP systems.  (Addresses Sourceforge Bug:
3898#1157933)
3899
3900Added a new function to the blkid library, blkid_probe_all_new(),
3901which only probes newly added disk devices, and change
3902blkid_find_dev_with_tag() to use this function so that when a
3903requested tag is not found, devices that were previously not checked
3904are searched before searching all devices in the system.
3905
3906Added new functions to the blkid library, blkid_dev_set_search() and
3907blkid_dev_has_tag().
3908
3909E2fsck's problem strings can now use @m and @n as abbrevations for
3910"multiply-claimed" and "invalid", respectively.
3911
3912The e2fsprog.pot file now has an explanation of how the @-expansion
3913and %-expansion works, and strings in e2fsck/problem.c which contain @
3914characters now have comments in e2fsprogs.pot with the @-expansion to
3915make life easier for translators.
3916
3917Fixed missing return values in the ext2fs library which could cause it
3918to return random garbage in certain error conditions.
3919
3920Allow the current time to be overriden via the E2FSCK_TIME environment
3921variable for use in regression tests.
3922
3923The test scrpit driver program now exits with a non-zero status if
3924there any of its test that it ran failed.
3925
3926Fixed problems with parabuilds on SMP systems.  (Addresses Sourceforge
3927Bug: #1157933)
3928
3929Fixed "make check" so that it compiles correctly even when e2fsprogs'
3930header files have not be installed in the system include directories.
3931(Addresses Sourceforge Bug: #1180572)
3932
3933Fixed gcc -Wall nits.
3934
3935
3936E2fsprogs 1.37 (March 21, 2005)
3937===============================
3938
3939Add support for checking the validity of Extended Attributes stored in
3940inodes to e2fsck.
3941
3942Add support for dumping the contents of large inodes to debugfs,
3943including the extended attributes stored in inodes.
3944
3945Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3946when we create a new inode we make sure that the extra information in
3947the inode (any extra fields in a large inode and any ea-in-inode
3948information) is initialized correctly.  This can take place when
3949mke2fs creates the root and lost+found directory, when e2fsck creates
3950a new root inode or a new lost+found directory, and when the user uses
3951the debugfs write, mknod, or mkdir commands.  Otherwise, the newly
3952create inode could inherit garbage (or old EA information) from a
3953previously deleted inode.
3954
3955Fixed a bug in e2fsck so it would notice if a file with an extended
3956attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3957to zero.
3958
3959Added support to filefrag to detect files which are using the new
3960experimental file extents format, and use the non-ext2 algorithm in
3961that case.  Fixed a bug to avoid reporting a false discontinuity if
3962there is one or more unallocated blocks at the beginning of a file.
3963
3964Duplicated a check for noticing whether or not the number of blocks
3965(given a certain blocksize) is greater than 2**32 when the
3966BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size().  This
3967allows mke2fs to automatically use a larger blocksize when creating a
3968filesystem on a very large device when run on systems that do not
3969support BLKGETSIZE64.
3970
3971Fix the I18N build which was broken in e2fsprogs 1.36 because the
3972build system had been switched to treat the .gmo files as shipped
3973files (for backwards compatibility with systems that have older GNU
3974I18N tools installed), but the gen_tarball.in script was still
3975removing the .gmo files from the official source distribution.
3976
3977Fixed various Debian packaging issues --- see debian/changelog for
3978details.  (Addresses Debian Bugs ##296769, #299341)
3979
3980Programmer's notes:
3981-------------------
3982
3983Added new functions to the e2p library which convert between a string
3984and os_type: e2p_os2string() and e2p_string2os(), and used them to
3985make the generated binaries more compact.
3986
3987Fixed a compile-time error on Darwin systems.
3988
3989Cleaned up the lib/ext2fs Makefile slightly.
3990
3991
3992E2fsprogs 1.36 (February 4, 2005)
3993=================================
3994
3995All of the patches that were applied to Fedore Core 3's
3996e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3997lot of bug fixes first.  Users of Fedora Core 3 are strongly
3998encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3999
4000Add support for filesystem with the online resizing via resize inode
4001feature.  Fixed numerous bugs from the Fedora patches.  The Fedora
4002patches also didn't bother to do any consistency checking on the
4003resize inode, or add any tests to the regression test suite.  The "-R
4004resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
4005being listed in mke2fs's usage message.  All of these shortcomings
4006have been corrected.
4007
4008E2fsck can also also fix filesystems trashed by Fedora's resize2fs
4009program.  In order to do this, the user must run the commands:
4010
4011	debugfs -w /dev/hdXXX -R "features ^resize_inode"
4012        e2fsck -f /dev/hdXXX
4013
4014Optionally, the ext2prepare command can be used to re-enable online
4015resizing after the filesystem has been fixed.
4016
4017The fsck program will now accept an optional filedescriptor argument
4018to the -C option.  (The Fedora version of this patch would sometimes
4019cause fsck to ignore a parameter on fsck's command line in some rare
4020cases, sigh.)
4021
4022Make sure e2fsprogs doesn't write garbage into the reserved portion of
4023large inodes.
4024
4025Make sure resize2fs releases the blocks belonging to the old inode
4026table blocks when moving the inode table.  (Addresses Debian Bug:
4027#290894)
4028
4029Skip the r_resize_inode test if resize2fs is not compiled (due to
4030configure --disable-resizer)
4031
4032E2fsck now checks the summary filesystem accounting information, and
4033if any of the information is obviously wrong, it will force a full
4034filesystem check.  (Addresses Debian Bug #291571)
4035
4036Fix e2fsck to not complain when the resize_inode feature is enabled,
4037s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
4038the resize inode.
4039
4040Fix e2fsck to note delete symlinks that contain an extended attribute
4041after the ext_attr feature flag has been cleared.  (Addresses Red Hat
4042Bugzilla #146284).
4043
4044Add new utility program, copy_sparse.c, which is very useful
4045for dealing with large sparse files (such as e2image files).
4046
4047Add support for jnl_blocks[] for debugfs's set_super_value.
4048
4049Fix filefrag so that it works correctly with sparse files.
4050
4051Filefrag -v will print first and last blocks.
4052
4053Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
4054and dumpe2fs.
4055
4056Add mke2fs support so that it can support filesystems larger than 4TB
4057automatically, by retrying with a 4k blocksize if the device size is
4058too big to be expressed using a 1k blocksize.  (Addresses Sourceforge
4059bug #1106631)
4060
4061Change blkid to test for NTFS first because Windows sometimes doesn't
4062clear enough of the parition to confuse the probing routines into
4063thinking the old filesystem type is still valid.  (Addresses Debian
4064Bug #291990)
4065
4066Add support for swap partition label and uuid's in the blkid library.
4067
4068Add support to the blkid library to recognize Oracle ASM volumes.
4069
4070Make blkid -t display all devices that match the specified criteria,
4071not just the first one, and work more consistently when the blkid
4072cache file is not available or set to /dev/null.  (Addresses Debian
4073Bug #290530 and #292425)
4074
4075Badblocks will now correctly display block numbers greater than
4076999,999,999 in its progress display.
4077
4078The tune2fs program will not allow the user from setting a ridiculous
4079number of reserved blocks which would cause e2fsck to assume the
4080superblock was corrupt.  E2fsck's standards for what is a ridiculous
4081number of reserved block has also been relaxed to 50% of the blocks in
4082the filesystem.
4083
4084The blkid library will return vfat in preference to msdos, and ext3 in
4085preference to ext2 (if the journalling flag is set) so that mount will
4086do the right thing.  (Addresses Debian bug #287455)
4087  
4088Mke2fs will now use the -E option for extended options; the old -R
4089(raid options) option is still accepted for backwards compatibility.
4090Fix a double-free problem in resize2fs.  (Red Hat Bugzilla #132707)
4091
4092Mke2fs will now accept a size in megabytes, gigabytes, and other units
4093(via "32m" or "4g" on the command line) if the user finds this more
4094convenient than specifying a block count.
4095
4096Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
4097cache conherency problem.
4098
4099Debugfs now supports a new command, set_inode_field, which allows a
4100user to manually set a specific inode field more conveniently, as well
4101as set entries in the indirect block map.
4102
4103Debugfs's set_super_value command has been enhanced so that the user
4104can set most superblock fields, including the date/time fields and
4105some of the more newsly added superblock fields.
4106
4107E2fsprogs programs now accept an offset to be passed to the file
4108specifiers, via the syntax: "/tmp/test.img?offset=1024".
4109
4110E2fsprogs programs will now accept blocksizes up to 65536; kernel
4111support on the x86 doesn't exist for now, but it can be useful on
4112other architectures with page sizes greater than 4k.  There are 2.6
4113kernel patches out there which enable this, but they are of this
4114writing still experimental.
4115
4116The e2image command now takes the -s option which will scramble
4117directory entries for raw image files.
4118
4119Fix a file descriptor leak in the filefrag program.
4120
4121Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
4122present.
4123
4124Fix bug in debugfs where kill_file would lead to errors when deleting
4125devices and symlinks.  (Sourceforge Bugs #954741 and #957244)
4126
4127Fix bug in the blkid library when detecting the ocfs1 filesystem 
4128
4129Remove obsolete EVMS 1.x and a.out DLL support.
4130
4131E2fsck will attempt to recover from a journal containing illegal blocks.
4132
4133Fixed two potential ordering constraint problems in e2fsck which might
4134cause the filesystem to be corrupted if e2fsck is interrupted during a
4135(extremely narrow) race window.  Thanks to Junfeng Yang from the
4136Stanford Metacompilation group for pointing this out.
4137
4138Fixed bug in e2fsck where it would not accurately detect whether or
4139not the system is running on adaptor if the ACPI device representing
4140the AC adapter didn't correspond to the what was used on IBM
4141Thinkpads.
4142
4143Change e2fsck to accept directories greater than 32MB.
4144
4145Fix e2fsck so that a checkinterval of zero disables a time-based check
4146of the filesystem.
4147
4148Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4149to the PAGER environment variable.  (Addresses Debian Bug #239547)
4150
4151Tune2fs will not mark rewrite the superblock if the feature bitmasks 
4152are not modified.
4153
4154The debugfs program will set the filetype information when creating a
4155link.
4156
4157Add debugfs -d option to use a separate source of data blocks when
4158reading from an e2image file.
4159
4160Add e2image -I option which allows the e2image metadata to be
4161installed into a filesystem.
4162
4163Fixed bug in the badblocks program which caused "done" to always
4164appear in english even when a translation was available.  (Addresses
4165Debian Bug #252836)
4166
4167The blkid program has a new option -o which controls the output format
4168of the blkid program; this is makes blkid more convenient to use in
4169shell scripts.
4170
4171Fix a minor bug in uuid library, which was not using the full 14 bits
4172of clock sequence when generating UUID's.
4173
4174Fix a Y8.8888K problem in the uuid library.
4175
4176Logsave now creates a new session id for itself to avoid getting
4177killed by init whan transitioning between init levels.
4178
4179Change the licensing of the UUID library to be the 3-clause BSD-style
4180license; this allows Apple to use the uuid library in Darwin.
4181
4182Add ocfs and ocfs2 probe support into the blkid library.
4183
4184Fix a memory and file descriptor leak in the blkid library.
4185
4186The blkid library will revalidate the device if the system time is
4187earlier than last verification time of the device, since that
4188indicates that the system time is probably nottrustworthy.
4189
4190The blkid library will override the default location of the blkid.tab
4191file by the BLKID_FILE environment variable, if it is available.
4192
4193Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4194
4195Add various portability fixes for lame new versions of glibc, Darwin
4196and GNU/KFreeBSD, as well as removing XSI:ism's.  (Addresses Debian
4197Bugs #239934, #264630, #269044, #255589, #289133)
4198
4199Add support for Windows 9x/NT under Cygwin.
4200
4201Updated and clarified various man pages.  (Addresses Debian Bugs #236383,
4202	#241940, #238741, #242995, #256669, #268148, #256760, #273679)
4203
4204Updated and fixed translations.   (Addresses Debian bugs #244105, #262836)
4205
4206Update the rpm spec files so that it works better with Fedora core 2
4207and RH9.
4208
4209Fixed various Debian packaging issues (see debian/changelog).  In
4210particular, fixed the Debian initrd scripts.  (#241183, #248050,
4211#253595, #247775)
4212
4213
4214Programmer's notes: 
4215-------------------
4216
4217Fixed various gcc -Wall warnings.
4218
4219The uuid library now has new functions uuid_unparse_upper() and
4220uuid_unparse_lower() which forces the case of the hex digits to be
4221upper case, or lower case.
4222
4223The build process has been speeded up by enhancing the subst program
4224to update the modtime on the generated files even when the generated
4225file hasn't changed.
4226
4227The uuid library now uses C99 stdint.h types instead of custom types.
4228
4229Updated config.guess and config.sub with newer versions from the FSF.
4230
4231Removed out of date .cvsignore files from the source distribution.
4232
4233The ext2fs_unlink() function will return an error if both the name and
4234inode number are unspecified, to avoid doing something surprising
4235(such as unconditionally deleting the first directory entry).
4236Directory entries are now deleted by coalescing them with the previous
4237directory entry if possible, to avoid directory fragmentation.  This
4238is not an issue with the e2fsprogs suite, but may be a problem for
4239some of the users of libext2fs, such as e2tools.
4240
4241Add support for version numbers of the form "1.36-rc1".
4242
4243Fix build of mke2fs.static.
4244
4245Add basic ext2fs library support for large (EA in inode) inodes.
4246
4247The test_io mechanism can now abort after n reads or writes to a
4248particular block.  The block is specified by TEST_IO_BLOCK environment
4249variable, and the read/write count by the TEST_IO_READ_ABORT and
4250TEST_IO_WRITE_ABORT environment variables.  The block data is now only
4251dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4252
4253UUID_DEFINE() in the uuid library now creates a static variable, with
4254__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4255be used in header files.
4256
4257Add support for the install-strip and install-shlibs-strip targets, as
4258suggested by the GNU coding guielines.  "make install" no longer
4259strips the binaries which are installed.
4260
4261Remove support for the --enable-old-bitops configure option which was
4262only for very old sparc systems.
4263
4264Remove support for --enable-clear-htree; this was only needed during
4265the early development of the htree patch.
4266
4267Use Linux-kernel-style makefile output so it is easier to see compiler
4268warnings.
4269
4270Update gettext files to version 0.14.1.
4271
4272Update to use autoconf 2.5x.
4273
4274Improved support for compiling e2fsprogs under dietlibc.
4275
4276Make e2fsprogs portable to Solaris and FreeBSD systems.
4277
4278Add blkid_verify(), blkid_get_library_version(), and
4279blkid_parse_version_string() functions to the blkid library.
4280
4281Add pkg-config files for e2fsprogs's libraries.
4282
4283Fix "make uninstall" to so that it removes everything that is installed.
4284
4285Add a configure --enable-maintainer-mode option which enables the
4286makefile rules to rebuild the configure script from configure.in, and
4287to reubuild the .gmo files in po directory.
4288
4289Drop the sparc assembly bitwise operations; it's less efficient
4290than the GCC 3.4 compile code and triggers compiler warnings on
4291sparc64.  Thanks to Matthias Andree for his analysis and suggestions.
4292(Addresses Debian Bug #232326)

4294
4295E2fsprogs 1.35 (February 28, 2004) 
4296==================================
4297
4298E2fsck has a new -k option, which in conjunction with the -c options,
4299preserves the existing badblocks list.
4300
4301Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
4302
4303E2fsprogs will now deal correctly with symlinks that contain
4304extended attribute information, which can be created using SE Linux.
4305(Addresses Debian Bug #232328)
4306                                                                               
4307Remove a double longjump into an invalid stack frame bug in e2fsck.
4308(This was during an abort sequence, which normally worked on Linux and
4309caused a core dump on other operating systems.)
4310
4311Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
4312(the NLS library will replace "" with the .po header information).
4313 
4314Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4315dump due to a division by zero error.  (Addresses Debian bug #207082)
4316
4317Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4318when reconnecting a directory requires creating a lost+found
4319directory.  (Addresses Debian bug #219640).
4320
4321Fixed a bug where e2fsck would bomb out if a journal needed to be
4322replayed when using an alternate superblock.
4323 
4324E2fsck will give an extra grace period before actually forcing a check
4325if the laptop is running on battery.  The next time fsck runs while
4326the system is on the AC mains, or after the grace period is exceeded,
4327the filesystem will be checked.  (Addresses Debian bug #205177)
4328
4329E2fsck will inform the user when there are 5 or fewer mounts before a
4330filesystem check will be forced.  (Addresses Debian bug #157194)
4331
4332Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4333We now correctly handle the case where there is an overlap between a
4334block group descriptor or a superblock and a bad block indirect block.
4335In the case where the indirect block is corrupted, we now suggest
4336"e2fsck -c".
4337
4338Fix byte swap bugs in e2fsck that caused the journal backup location 
4339in the superblock and symlinks created by SE Linux to be cleared
4340by e2fsck on big-endian machines.  (Addresses Debian bug #228723)
4341
4342E2fsck -c now replaces the current list of bad blocks with the ones
4343found by badblocks.
4344
4345Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4346non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4347
4348Fix a potential bug in e2fsck which could cause it to core dump when
4349trying to print the location of the backup superblock.
4350
4351Protect against a potential core dump in e2fsck when printing a
4352message about backup superblocks.
4353
4354Add support for backing up the journal inode location in the
4355superblock.  E2fsck will automatically save the journal information in
4356the superblock if it is not there already, and will use it if the
4357journal inode appears to be corrupted.  ext2fs_add_journal_inode()
4358will also save the backup information, so that new filesystems created
4359by mke2fs and filesystems that have journals added via tune2fs will
4360also have journal location written to the superblock as well.
4361Debugfs's logdump command has been enhanced so that it can use the
4362journal information in the superblock.
4363
4364E2fsck will now update all superblocks when moving the journal inode.
4365  
4366Shrink the size of the e2fsck executable by moving some initialized
4367variables to the BSS segment.
4368
4369E2fsck will avoid printing the ^A and ^B characters which bracket the
4370progress bar when stdout and stdin are a tty device instead of a pipe
4371to another program.  (Addresses Debian bug #204137)
4372
4373Debugfs's mkdir command will automatically expand the directory if
4374necessary.  (Addresses Debian Bug: #217892)
4375 
4376Fixed a bug in debugfs so that copying a file from /dev/null uses the
4377correct mode bits.  (Addresses Debian Bug: #217456)
4378 
4379If the environment variables DEBUFS_PAGER and PAGER are not set,
4380debugfs now searches for the appropriate pager to use, beginning with
4381/usr/bin/pager, and then falling back to 'more' and 'less'.
4382(Addresses Debian bug #221977)
4383
4384Debugfs will now support 2.6 device numbers where the major or minor
4385number may be larger than 255.  (Addresses Sourceforge bug #865289)
4386 
4387Fix debugging printf in resize2fs.  (Addresses Debian Bug #271605)
4388
4389Chattr now stops processing options when it sees '--'.  (Addresses
4390Debian bug #225188)
4391
4392Fix regression tests so they work correctly when e2fsprogs is compiled
4393with configure --disable-htree.
4394
4395Fix bug in uuid library when there is no network card and the library
4396is generating a time-based uuid.  The random MAC address was not
4397correctly generated to be a multicast address.
4398 
4399Add compile_et extensions from Heimdall that were missed the first time
4400around.
4401
4402Fix bug in badblocks when using O_DIRECT; we need to make sure that
4403we're reading from an offset which is page aligned.  For read-only and
4404read-write tests, we try to recover after an error so that we can
4405continue reading on page-aligned boundaries.  (Addresses Debian Bug
4406#203713)
4407  
4408Badblocks now checks 64 blocks at a time instead of 16.  (Addresses
4409Debian bug #232240)
4410 
4411Updated and clarified various man pages.  (Addresses Debian Bug
4412#206845, #222606, #214920, #232406)
4413
4414Updated and fixed translations.   (Addresses Debian bugs #200086, #214633)
4415
4416Fixed various Debian packaging issues (see debian/changelog).
4417
4418Programmer's notes: 
4419-------------------
4420
4421Fixed a build problem so that e2fsprogs would compile with the
4422--enable-profile option to configure selected.  (Addresses Sourceforge
4423bug #811408)
4424 
4425Fixed C++ problems with the ext2fs.h header.  (Addresses Red Hat
4426Bugzilla Bug #112448)
4427                                                                               
4428Centralize code which calculates the location of the superblock
4429and block group descriptors so that it is in a single library routine.
4430
4431Added two new functions, ext2fs_file_open2() and
4432ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4433
4434Fix compile_et to output the correct prototype for
4435initialize_xxx_err_table_r() in the header file.  (Addresses Debian
4436bug #204332)
4437
4438In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4439  
4440Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4441present.  This is for when we try stuffing an int into void * pointer.
4442
4443Fix type-punning which can cause gcc 3.x to miscompile code by getting
4444confused about pointer aliasing.  ext2fs_getmem(), ext2fs_free_mem(),
4445and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4446**'.  The EVMS code uses an ugly union approach since we don't want to
4447modify the EVMS interfaces. 
4448
4449Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4450aid build process on systems can use invoke GNU make as "gmake".
4451
4452Added regression testing for mke2fs.
4453
4454Fixed gcc -Wall nitpicks.
4455
4456Fixed various compiler warnings.
4457
4458Add portability fixes for FreeBSD and for using fsctl under Darwin to
4459support ext2 ioctl's.
4460
4461
4462E2fsprogs 1.34 (July 25, 2003)
4463===============================
4464
4465Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4466a tight loop while waiting for a child fsck to exit in some cases.
4467This burns CPU times which slows down the low-level filesystem check.
4468
4469Added code to mke2fs to assure that the default block size for a
4470filesystem is at least as big as the sector size of the device, if it
4471can be determined.
4472
4473Changed mke2fs and resize2fs to round the default size of a filesystem
4474to be an even multiple of the VM pagesize in order to avoid a Linux
4475kernel bug introduced when the storage of the buffer cache was moved
4476into the page cache.
4477
4478Mke2fs will warn the user when creating a filesystem with journaling
4479and a blocksize greater than 4096.  (Addresses Debian bug #193773)
4480
4481Fixed a bug in resize2fs which caused it to fail on filesystems with a
4482non-empty bad block list.  Resize2fs now discards any blocks on the
4483badblock list which are no longer part of the filesystem as the result
4484of a filesystem shrink.  (Note: this means that shrinking and then
4485enlarging a filesystem is no longer a reversible operation;
4486information about bad blocks in the part of the filesystem which is to
4487be chopped off will be lost.)
4488
4489Changed resize2fs so the user can use prefixes to specify the units of
4490the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4491and to make the error and informational messages explicitly display
4492the blocksize used by the filesystem, in order to avoid confusion.
4493(Addresses Debian bug: #189814)
4494
4495Added a new debugfs command, dump_unused, which dumps the contents of
4496all unused blocks to stdout.  (Useful as an emergency try-to-find
4497deleted data command.)
4498
4499Added a new debugfs command, imap, which prints the location of a
4500specified inode in the inode table.
4501
4502Fixed a bug in the badblocks program which caused it to use one bit of
4503randomness in its non-destructive read/write test, instead of using a
4504full 8 bits of randomness.
4505
4506Added a new option (-t) to badblocks, which allows the user to control
4507the test pattern(s) used when checking a disk.
4508
4509The blkid probe function now more correctly detects UDF filesystems.
4510
4511Fixed a bug in the blkid library which caused it to not update its
4512cache if a filesystem changes from having a label to not having a
4513label.
4514
4515Fixed a bug in the blkid library wihch could avoid an infinite loop
4516in blkid_find_dev_with_tag() if /proc is not mounted and there the
4517/etc/blkid.tab file has not yet been created.
4518
4519Fixed the badblocks program so that the destructive read/write test
4520honors the -c option, and to use O_DIRECT when possible to avoid
4521thrashing the system block buffer cache.
4522
4523Fixed various NLS issues.
4524 - Added Czech and Swedish translations
4525 - Removed testing NYC translation
4526 - Fixed NLS support for message abbrevations in e2fsck
4527 - Remove de-utf.po, since we shouldn't have two versions using different
4528	charset encodings.
4529 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 
4530	simplify the statistics reporting in e2fsck.
4531
4532Changed configure.in so that its defaults for *BSD systems no longer
4533build an fsck wrapper, and not to install in /usr/local by default.
4534
4535Fixed some minor spelling errors/typo's in e2fsck and the configure
4536script.
4537
4538Fixed various Debian packaging issues (see debian/changelog). 
4539
4540Updated and clarified man pages.  (Addresses Debian Bug #195616)
4541
4542Programmer's notes: 
4543-------------------
4544
4545Fix gcc -Wall nitpicks.
4546
4547Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4548NLS support by default.  (Added partial workaround for gettext/Darwin
4549incompatibility problems.)
4550
4551Added full MIT KRB5 and Himdall compaibility support to the com_err
4552library and the compile_et program.  (Addresses Debian bug #191900)
4553
4554Added the blkid_known_fstype() function to the blkid library, which
4555returns true if it is passed a filesystem type which is recognized by
4556the blkid probing functions.
4557
4558Improved the documentation for the blkid library.
4559
4560Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4561returns the hardware sector size of a device, if it is available.
4562
4563Added a dependency in the blkid library's .so file to the uuid
4564library, since the former uses the latter.  (Addresses Debian bug
4565#194094)
4566
4567Added --with-diet-libc and --disable-evms to the configure script.
4568
4569Fixed a minor memory leak in the badblocks program.
4570
4571Fixed a portability problem in tune2fs --- not all systems have strptime().
4572
4573Fixed a portability problem in debugfs with the use of getopt() more
4574than once.  Old-style BSD, new-style BSD, and Linux C libraries all do
4575things differently.
4576
4577Add support Windows support to ext2fs_get_device_size().
4578
4579Added (normally disabled) debugging code to the Unix I/O manager which
4580causes it to disable all userspace caching if the NO_IO_CACHE is
4581defined.
4582
4583Changed the test I/O manager so it can always be linked into e2fsck,
4584mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4585configure script.  The test I/O manager will only print any debugging
4586information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4587variables are set, which specifies which I/O operations are logged and
4588a block number to watch, respectively.  The log messages are sent to
4589stderr by default, unless a filename is specified via the
4590TEST_IO_LOGFILE environment variable.
4591
4592
4593E2fsprogs 1.33 (April 21, 2003)
4594===============================
4595
4596Added a new utility program, logsave, which captures the output of a
4597command in a log file, even if the containing directory hasn't been
4598mounted yet (in which case the it saves the output in memory until it
4599can write out the logfile).  This is useful for capturing the
4600output of fsck during the boot sequence.
4601
4602Fixed some portability problems that were causing problems under
4603the Cygwin32 environment.
4604
4605Mke2fs now interprets a negative number to the -b option as a minimum
4606block size.
4607
4608Fixed a bug in mke2fs which was incorrectly checking the argument to
4609the -g option if the default block size was used.  (Addresses Debian
4610bug #188319)
4611
4612Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4613it can not find filesystem checkers for jfs, reseirfs, and xfs.
4614
4615E2fsck now updates the global free block and inode counters from the
4616block group specific counters quietly.  This is needed for an
4617experimental patch which eliminates locking the entire filesystem when
4618allocating blocks or inodes; if the filesystem is not unmounted
4619cleanly, the global counts may not be accurate.
4620
4621Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree.  (EVMS
46222.0 is not yet supported; this only pulled in the bug fixes: fixed
4623possible hangs caused by bugs in calling waitpid, and not setting the
4624pipe to non-blocking mode; also fixed a file descriptor leak; made
4625sure all functions call log entry/exit functions.)
4626
4627Badblocks now flushes its output file as bad blocks are discovered.
4628
4629The uuid library is now more paranoid about assuming the correctness
4630of the /dev/random device; it mixes in a stream of bytes from
4631random/srandom, just in case.
4632
4633Update Debian files to reflect the fact that I am now the Debian
4634maintainer of e2fsprogs.  Other various Debian-specific packaging
4635cleanups.
4636
4637Move the source tarball generation functions from the top-level
4638makefile to the util/gen-tarball script.  
4639
4640Updated the Turkish .po translation file.
4641
4642Added Heimdal and MIT krb5 extensions to the com_err library to make
4643it more compatible with com_err libraries from those distributions.
4644
4645Changed dumpe2fs to always display the superblock fields relating to
4646the journalling and/or directory indexing feature even if those
4647features are not enabled.
4648
4649Updated and clarify copyright statement vis-a-vis alpha releases of
4650e2fsprogs.
4651
4652The ss library will now try to dynamically link to the readline
4653library and use it if it is present in the system.  This means that
4654the debugfs program now has line editing and history features.  The
4655SS_READLINE_PATH environment variable is used to find a readline or
4656readline-compatible library.
4657
4658E2fsck now finds most duplicate filenames (all when rebuilding all
4659directories via the -D option) and offers to delete or rename
4660duplicate filenames/directory entries.  (Addresses Debian Bug #176814).
4661
4662Fix bug in e2image.  When writing out a raw image file, include data
4663blocks from symlinks that do not store the symlink within the inode.
4664
4665Fix bug in resize2fs which incorrectly moved the block and inode
4666bitmaps for sparse superblock filesystems and incorrectly marked
4667blocks as in use.  (Addresses Debian bug #174766)
4668 
4669Added a new shared library, the blkid library, which efficiently
4670allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4671and UUID filesystem specifiers without needing to search all of the
4672devices in the system.  Instead, the device is looked up in a cache
4673file, and then verified to make sure the blkid cache is correct.
4674
4675Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4676the device name, using the blkid library.  (Addresses Debian bugs
4677#166048, #179671)
4678
4679Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4680used for spaces in device labels.
4681
4682Removed 32-bit limitations for debugfs's dump command.
4683
4684If the user specifies a large number of inodes, Mke2fs will
4685automatically adjust the number of blocks per group to find a valid
4686set of filesystem parameters.
4687
4688Add workaround to detect broken MD devices where when some of the
4689underlying devices are marked read-only, writes to the MD device are
4690silently dropped.  E2fsck will detect if there is an attempt to run
4691the journal twice, and abort with an error if this is the case.
4692(Addresses IBM Bugzilla bug #1226)
4693
4694E2fsck will print an error if more than one of the -p/-a, -n or -y
4695options are specified.
4696
4697E2fsck will fix HTREE corruptions in preen mode, without stopping the
4698boot process.  This is needed because the 2.4 ext2 filesystem
4699accidentally had the INDEX_FL backwards compatibility code removed.
4700
4701Mke2fs no longer creates filesystems with the dir_index flag set by
4702default; the user has to specifically request it.
4703
4704Update and clarified various man pages. (Addresses Debian bugs
4705#173612, #175233, #175113, and #170497, #185945, #188318)
4706
4707Created man page for the mk_cmds program (from the libss library).
4708
4709Programmer's notes: 
4710-------------------
4711
4712Fix various gcc -Wall nits.
4713
4714Fixed a lot of portability problems that caused e2fsprogs not to build
4715successfully under Solaris and Apple/Darwin.
4716
4717Fixed a Makefile dependency to allow building e2fsprogs using parallel
4718make jobs.
4719
4720Changes to create a subset distribution which consists only of the
4721et, ss, uuid, and blkid libraries.  The configure script and top-level
4722makefile were changed to support working with a subset distribution.
4723
4724Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4725actually used, and might people who are looking for
4726EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4727
4728Updated debian files to fix a number of Lintian warnings.
4729
4730Updated config.guess and config.sub with newer versions from the FSF.
4731
4732Removed unnecessary libraries from being linked into the fsck, lsattr, 
4733chattr, and blkid executables.
4734
4735E2fsprogs 1.32 (Nomvember 9, 2002)
4736==================================
4737
4738Fixed a bug in the Unix I/O routines which caused needless writebacks
4739of clean blocks from the unix_io cache (they were erroneously marked
4740as being dirty, so they were getting written back to disk before
4741getting evicted from the disk cache).  This was harmless, but it
4742significantly slowed down e2fsck.
4743
4744Made some other minor optimizations to the Unix I/O routines to save a
4745small amount of CPU time.
4746
4747Updated internationalization files.
4748
4749
4750E2fsprogs 1.31 (Nomvember 8, 2002)
4751==================================
4752
4753Update EVMS ext2fsim plugin with EVMS 1.2.  (We still support
4754compiling the fsim plugin with EVMS 1.0 and 1.1.)  Add better error
4755handling for child process that die unexpectly.  Add a hack to force
4756mkfs to create filesystems that won't cause problems with hardware
4757that has 2k or 4k minimum blocksize requirements.  Read from child
4758processes in non-blocking mode, so that the GUI continues to update.
4759
4760Fix e2fsck so that it returns the appropriate exit code when the root
4761filesystem has been changed, so that system's rc scripts will be told that 
4762the system needs to be rebooted.
4763
4764Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4765was set, some of the descriptor blocks that should have been written
4766out were getting skipped.
4767
4768Changed e2fsck to force out changes to the backup copies of the
4769superblock and block group descriptors when important changes are made
4770to those data structures.
4771
4772Fix a bug where e2fsck could erroneously mark a filesystem as being
4773clean if a check of dirty filesystem is interrupted with a ^C.  (Bug
4774introduced in e2fsprogs 1.28.)
4775
4776If journal debuging is enabled using --enable-jbd-debug, the debugging
4777level is now set via the E2FSCK_JBD_DEBUG environment variable.
4778
4779If byteswapping support is disabled using configure --disable-swapfs,
4780skip the tests which depend on byte-swapping, so that "make check"
4781won't bomb out.
4782
4783Lshattr will now display the indexed directory flag.  Also, some of
4784the more esoteric compression flags are supressed unless compression
4785support has been enabled.
4786
4787Update man pages.
4788
4789
4790E2fsprogs 1.30 (October 31, 2002)
4791=================================
4792
4793When resizing a filesystem, and inodes need to moved, resize2fs will
4794update the inode's ctime field, and the mtime field of the containing
4795directories, so that incremental backups using dump/restore will work
4796correctly.
4797
4798In order to avoid spurious errors, e2fsck wil check the last
4799superblock write time to determine whether or not it can safely use
4800the LOW_DTIME checks to determine if there are inodes on the orphan
4801inode linked list that had somehow gotten disconnected.  (Addresses
4802Sourceforge bug #620980)
4803
4804Partition in /proc/partitions that being with the string "lvm" are
4805considered real partitions even if they do not end with a number.
4806
4807Fixed a bug in the the uuid generation function, where if /dev/urandom
4808is not present, but /dev/random is, and there isn't sufficient
4809entropy, the get_random_byte function could spin a loop forever.
4810
4811E2fsck, mke2fs, etc. will now reliably notice when image files are
4812mounted using the loopback interface.  (Addresses Sourceforge bug
4813#619119)
4814
4815When flushing buffers (as is done by badblocks, for example) check to
4816see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4817FDFLUSH ioctl which causes the MD device driver which causes confusing
4818syslog messages about obselete ioctl messages.  (Addresses Sourceforge
4819bug #545832).
4820
4821Debugfs's write command now checks to see if the destination filename
4822exists before creating it.  (Addresses Sourceforge bug #478195.)
4823
4824When installing man pages, search for compressed man pages using all
4825commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4826
4827Fixed a bug in fsck where multiple filesystems specified on the
4828command were not being checked in parallel due to a logic bug
4829introduced to support the FSCK_MAX_INST environment variable.
4830
4831We have added a new superblock field, s_mkfs_time, which indicates
4832when a filesystem was created.  It is set via mke2fs, and printed out
4833by dumpe2fs, but is not actually touched by the kernel.
4834
4835Dumpe2fs has been made more robust by not aborting if there is an
4836error reading the block/inode bitmaps; instead it will still print out
4837the location of the block/inode bitmaps and inode table.
4838
4839Add support for the an alternative block group descriptor layout which
4840allows for on-line resizing without needing to prepare the filesystem
4841in advance.  (This is the incomat feature flag meta_bg.)
4842
4843Add support for storing default mount options in the superblock, so
4844that the filesystem can be mounted with specific mount options without
4845needing to specify them on the mount command line or in the /etc/fstab
4846file.
4847
4848Add support for a new inode flag, which is to be used for indicating
4849the top of directory hierarchies for the Orlov block allocator.
4850
4851Fix e2fsck so that if it creates the lost+found directory, it does so
4852with the more apporpriate permissions of 0700.  Also change
4853mklost+found so that it also creates the directory 0700.
4854
4855Fixed format bug in e2fsck if NLS is in use.
4856  
4857Add a German translation for e2fsprogs's NLS support.
4858
4859Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4860the beginning of the inode table.  This won't matter much, since if
4861there is a bad block at the beginning of the inode table, the root
4862directory won't be available.  But at least e2fsck won't crash in this
4863case.
4864
4865Fixed endian problems in the htree code for e2fsck and debugfs.
4866  
4867When byte-swapping a filesystem on a PPC architecture, byte-swap the
4868bitmaps since the historical big-endian ext2 variant had byte-swapped
4869bitmaps, and the ext2fs library assumes this.  This fixes the
4870regression test suite on PPC machines.
4871
4872Fix e2image so that it handles a bad block in the inode table
4873appropriately.
4874
4875E2fsck now uses a more sophisticated algorithm to salvage corrupted
4876directories that recovers more information in the corrupted directory
4877block.
4878
4879E2fsck now performs additional consistency checks on indexed (HTREE)
4880directories.
4881
4882Fix bug where efsck might get confused about whether a completely
4883empty directory block is an empty leaf block or an interior htree
4884node.  This could cause e2fsck to get confused into think that a valid
4885indexed directory was corrupted.
4886
4887E2fsck no longer creates an empty directory entry at the end of a
4888directory block when optimizing a directory.  This would cause some
4889earlier versions of the dxdir kernel code to corrupt the directory
4890when attempting to split a node containing an empty directory entry.
4891
4892E2fsck could sometimes in rare circumstances leave the indexed flag
4893set after a small directory was optimized by compressing it instead of
4894indexing it.  (This should never happen in real life, since
4895directories that small wouldn't have been indexed, but better safe
4896than sorry.)
4897
4898E2fsck now only updates the master superblock in all cases.  This
4899slightly shortens its run time.
4900
4901Ext2ed can deal with directory entries of length 0; previously it
4902would get stuck in an infinite loop.
4903
4904Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4905specifiers.  (Sourceforge patch #613447)
4906
4907Badblocks will now work correctly on read-only devices such as
4908CD-ROM's.  (Sourceforge patch #600451)
4909
4910Updated and clarified man pages.  (Addresses Debian bug #167108)
4911
4912
4913E2fsprogs 1.29 (September 24, 2002)
4914===================================
4915
4916Fixed a bug in e2fsck which could corrupt a directory when optimizing
4917it (via the -D option) or rebuiliding the hash tree index with a 1 in
4918512 probability, due to a fence post error.
4919
4920Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4921work correctly.
4922
4923Mke2fs now enables the directory indexing flag by default.  (Since
4924this is a compatible feature flag, it's safe to do so.)
4925
4926Tune2fs will support setting the directory indexing feature flag.  It
4927will automatically set up the default hash algorithm and hash seed
4928fields in the superblock.
4929
4930If the bone-headed user enters the root filesystem twice in
4931/etc/fstab, the -R option which skips the root filesystem will skip
4932all of them.  (Addresses Debian bug #159423).  Note!  This is not a
4933precedent for dealing intelligently with any other kind of doubled
4934entry in /etc/fstab!
4935
4936
4937Programmer's notes: 
4938-------------------
4939
4940Removed perror declaration in lib/et/internal.h.  All modern systems
4941can be expected to define perror() these days.  Besides, the lib/et
4942code wasn't using perror at all anyway.  :-)
4943
4944
4945E2fsprogs 1.28 (August 31, 2002)
4946================================
4947
4948Add support for the Hashed-Tree Directory Indexing to e2fsck.  Support
4949for setting the htree flag is not included yet, although it can be
4950manually turned on via the debugfs program.
4951
4952Clarified e2fsck error message which is printed when it cannot find
4953sufficient contiguous block when relcating filesystem metadata.
4954
4955Added support for building an EVMS plugin module for ext2/3.  This
4956module is substantially the same as the EVMS module shipping with EVMS
49571.1, with one or two bugfixes.  E2fsprogs can also build this plugin
4958for use with EVMS 1.0 (which did not include the ext2 plugin module),
4959if the configure --enable-old-evms flag is given.
4960
4961Fsck will search through EVMS volumes when trying to resolve
4962filesystem specifications such as LABEL=xxx or UUID=xxx.
4963  
4964Added a new utility program, /sbin/findfs, which will return
4965filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4966the device name.
4967
4968Update and clarified various man pages. (addresses Debian Bug #145044,
4969#146437, #131350, #151990, #144621, #141938)
4970
4971If there are no filesystems specified on fsck's command line, fsck now
4972treat that as if the -As options were given.  Previously it would
4973simply do nothing.  (Addresses Debian Bug #153102)
4974
4975Mke2fs no longer treats a failure to be able to clear the MD signature
4976at the end of the filesystem as a fatal error.  (Addresses Debian Bug
4977#155007)
4978
4979The e2p library functions (which are used by lsattr and chattr) now
4980double check to make sure the file is a regular file or directory
4981before attempting to use the ext2 ioctls.  Some device drivers
4982unfortunately respond to the ext2 ioctl's with unknown behaviour.
4983(Addresses Debian Bug #152029).
4984
4985The extended attribute handling has been updated to correspond with
4986the latest V2 bestbits ACL code.
4987
4988Fixed bug in e2fsck which caused it to not clear the dtime field when
4989processing truncated inodes on the orphan list.  This could cause data
4990loss(!) if a filesystem is rebooted before a truncate has been
4991committed.
4992
4993E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4994algorithms.  This makes e2fsck much faster in the case of severely
4995corrupted filesystems where a large number of blocks are claimed by a
4996large number of inodes.  (Thanks to the 2.5 IDE device driver for
4997inspiring this work.)
4998
4999Resize2fs has been significantly sped up when shrinking and expanding
5000a filesystem by a very small number of blocks (for example, when EVMS
5001is converting a partition to be an EVMS legacy volume).
5002
5003Added a new option to e2fsck, -D, which will optimize or compress all
5004of the directories in the filesystem.
5005
5006E2fsck now catches SIGINT and SIGTERM to make sure it will can
5007properly clean up and only exit at safe points.  Fsck will pass
5008SIGINT/SIGTERM to its child processes, and wait until they have all
5009exited before it exits.
5010
5011The uuid parsing code in the uuid library now properly complains when
5012an illegally formated uuid is presented to it.  (Addresses Debian bug
5013#152891)
5014
5015Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
5016and 2.4.17, since the workaround can cause problems when using a 2.4
5017kernel with an old version of glibc built with the 2.2 headers.
5018
5019Fixed a bug in mke2fs where it wasn't properly clearing the initial
5020superblock used by other filesystems.  (Addresses Debian bug #147256.)
5021
5022Added support for the synchronous directory feature written by Andrew
5023Morton.
5024
5025The debugfs program can delete directories using the rmdir command.
5026
5027Add support for 8k and 16k filesystems (for systems with page sizes
5028that are greater or equal to 8k or 16k, respectively).  Note that
5029these filesystems can not be mounted on x86 systems, or other systems
5030with only 4k page sizes, due to limitations in the current Linux VM
5031code.
5032
5033Resize2fs requires that the filesystem state be valid and have no
5034errors; otherwise, e2fsck -f must be run first.  (Previously it simply
5035required that the last fsck time be greater than the last mount time.)
5036
5037Configure now defaults the man pages directory to /usr/share/man on
5038Linux systems.
5039
5040E2fsck now offers to truncate inodes which contain too many blocks (so
5041that i_blocks would overflow.  Also fixed handling of large sparse
5042files.
5043
5044E2fsck now more completely checks for symlink validity, including
5045requiring NULL termination and length checks.
5046
5047E2fsck will offer to try forcing a disk write to remap a bad block
5048after finding a read error when reading a filesystem metadata block.
5049
5050Fixed a bug in debugfs which caused the -b and -s options to crash
5051debugfs, as well as breaking the testb, setb, and clearb functions.
5052
5053Added a bmap command to debugfs which calculates the logical to
5054physical block mapping for a particular inode.
5055
5056Fixed a bug in code which checked to see if a device was mounted which
5057sometimes (rarely) failed in the case of a plain file.
5058
5059Fixed a bug in resize2fs where when it reported an error, it would
5060print a message erroneously indicating that the filesystem had been
5061resized before it aborted.
5062
5063When resizing a plain file which is smaller than the requested size,
5064resize2fs will attempt to extended the file so that programs like
5065e2fsck will not complain that the file is too small.
5066
5067Resize2fs will print the actual new size of the filesystem when it is
5068finished resizing.
5069
5070Fixed a bug in debugfs where "ls -l" would report incorrectl file type
5071information on big-endian systems.
5072
5073
5074Programmer's notes:
5075-------------------
5076
5077Fixed collisions with C++ reserved words.
5078
5079Added portability fixes for building e2fsprogs on the HURD and AIX.
5080
5081Added the ext2ed program for creation of test cases.  (ext2ed has many
5082limitations and bugs which make it unsuitable for production use.)
5083
5084The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
5085flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
5086name_len field is byte swampped on big-endian machines, since in the
5087V2 structure, name_len is a char field which is doesn't need to be
5088byte swapped --- except if an old-style kernel had byte-swapped the
5089name_len field as part of the V1 structure.
5090  
5091
5092E2fsprogs 1.27 (March 8, 2002)
5093==============================
5094
5095The warning messages for mke2fs now go to standard error.
5096
5097Fixed to make sure "make check" runs all of the test programs with
5098LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
5099
5100The mke2fs program checks the boot sector for the BSD disk label, and
5101avoids erasing it if it is there.
5102
5103Fixed a bug in e2fsck which caused it to core dump if the journal
5104inode was missing when it was supposed to be there.
5105
5106E2fsck now prints ranges in pass 5 when printing deltas for the block
5107and inode bitmaps.
5108
5109Debugfs's "ls -l" command now will print out the file type information
5110in the directory entry.
5111
5112Create man pages and hard links for fsck.ext3 and mkfs.ext3.  If
5113mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
5114
5115Debugfs can now examine the experimental directory indexing
5116information.
5117
5118Fixed bug in debugfs which caused it to core dump if modify_inode is
5119called without an open filesystem.
5120
5121The debugfs lsdel command now runs its output through a pager first.
5122
5123When installing manual pages, remove the compressed manual pages first.
5124
5125Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
5126
5127Fix the 2.4 resource limitation workaround introduced in 1.26 which
5128actually broke things on mips32, sparc32, and Alpha platforms.
5129
5130Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
5131(which is required by the newer libintl libraries).
5132
5133Programmer's notes:
5134-------------------
5135
5136Fixed various gcc -Wall complaints.
5137
5138Fixed a few memory leaks in the e2fsck journaling code, and in the
5139ismounted code checking for a swap device.
5140
5141Add new inode I/O abstraction interface which exports an inode as
5142an I/O object.
5143  
5144Exported ext2_file_flush as a public interface.
5145  
5146In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5147
5148Lots of small random portability fixes to make e2fsprogs build under
5149AIX --- even without the 5L compatibility toolkit, and even using the
5150uber-crippled AIX native C compiler.
5151
5152
5153E2fsprogs 1.26 (February 3, 2002)
5154=================================
5155
5156Dumpe2fs will keep going now if the bad block inode can't be read.
5157(Previously it stopped with a fatal error.)
5158
5159E2fsck will now give an opportunity to run the journal even if the
5160recovery flag is not set.  This is the default behaviour if e2fsck is
5161using a backup superblock, since the needs_recovery flag will never be
5162set in the backup superblock copies.
5163
5164E2fsck now automatically finds the backup superblock/group descriptors
5165even when the primary superblock is completely destroyed for 2k and 4k
5166filesystems.  (Previously it just guessed/assumed that we were dealing
5167with a 1k filesystem in that case, and users had to manually specify
5168the backup superblock number.)
5169
5170Fixed a bug in e2fsck where it dereferences a null pointer when there
5171is a problem opening a filesystem in preen mode.
5172
5173E2fsck now handles external journals correctly; previously it trashed
5174the external journal device if the journal needed to be replayed.
5175
5176Work around ulimit incompatibility problem caused by recent 2.4
5177kernels; the unix IO module will automatically try to set any resource
5178limits to be infinite on startup.
5179
5180Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5181bitmap if it wasn't present and the blocksize was 2k or 4k.
5182 (Addresses Debian Bug #116975)
5183
5184E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5185clearing the new V2 fields if they do not make sense or if the ext3
5186superblock is version 1 superblock.
5187
5188E2fsck will automatically relocate the ext3 journal from a visible
5189file (i.e., /.journal) to an hidden inode if the filesystem has been
5190opened read/write.  This allows the users to add a journal while the
5191filesystem is mounted, but the next time the system is rebooted, the
5192journal file will disappear.  This avoids problems with backups,
5193stupid operators with superuser bits, etc.
5194
5195Fix a bug in fsck where it would not support a filesystem type of
5196"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5197
5198Fsck now supports fstab entries of the form "ext3,ext2".  It will also
5199automatically identify reiserfs filesystems.
5200
5201The number of processes spawned by fsck can now be limited using the
5202FSCK_MAX_INST environment variable.
5203
5204Fsck now searchs the LVM proc hierarchy to find logical volumes which
5205should be searched for  UUID and label information.
5206
5207Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5208limit if at all possible, when opening a block device.  (The filesize
5209limit shouldn't be applied against writes to a block device.)
5210
5211In mke2fs and e2fsck, specifying the -c option twice will now do
5212a read/write test on the disk.  Update the man pages to encourage
5213using the -c option, and to discouraging running badblocks separately,
5214since users tend to forget to set the blocksize when running 
5215badblocks.
5216
5217Mke2fs now automatically clears the immutable attribute on a
5218pre-existing .journal file left over from a previous failed attempt to
5219add a journal to an alreadyy-mounted filesystem.
5220
5221Fixed mke2fs's exit codes to consistently indicate when the mke2fs
5222operation failed.
5223
5224Mke2fs now creates the lost+found directory with permissions of 0700,
5225so that files that had previously lived in protected directory are
5226safe if they get dropped in lost+found and the system administrator
5227doesn't deal with immediately.  (Addresses Debian #bug 118443)
5228
5229Mke2fs and e2fsck (and all programs that use the
5230ext2fs_check_if_mounted function) will now properly identify that a
5231device is mounted, even in cases where devfs has confused things with
5232multiple devices names with the same identity, or if a dim-witted
5233system administrator has done something stupid like creating device
5234file aliases in their home directory.  Also now checks for swap devices
5235by using /proc/swaps.  (Addresses Debian bug #106622)
5236
5237Added a new option (-T) to tune2fs which sets the time a filesystem
5238was last checked.
5239
5240Speed up e2image when creating sparse raw image files by optimizing
5241away excess lseek() system calls.
5242
5243Fix support of large (> 2GB) files when used as a filesystem in
5244mke2fs, tune2fs, debugfs, and findsuper.
5245
5246Debugfs's stat and icheck commands now properly deals with large (>
52472GB) files.
5248
5249Debugfs's set_super_value command now prints out the list of valid
5250superblock fields which can be set using the command.
5251
5252Debugfs's rm and kill_file command now updates the superblock free block
5253and inode counts, thus keeping the filesystem consistent.
5254
5255Debugfs's lsdel command now takes an optional argument which allows
5256the user to only see the most recently deleted files.
5257
5258A new command (undel) was added to debugfs which automates
5259undeleting a deleted inode and linking it back to a directory.
5260
5261Debugfs's ls command now takes a new option, -d, which lists 
5262deleted directory entries.
5263
5264Debugfs's testb, freeb, setb, and find_free_block commands now take an
5265optional count argument.
5266
5267Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5268be used to signal that a particular inode should not be eligible for
5269tail-merging --- this is needed for programs like LILO.
5270
5271The findsuper (an unreleased, uninstalled utility program) has been
5272improved to add extra validity checks and to add a progress meter.
5273(It is still an unsupported program; the officially supported way to
5274recover from a trashed partition table is to use gpart; findsuper is
5275for wizards only.  :-)
5276
5277Debugfs was fixed to compile with "configure --disable-swapfs".
5278
5279Cleaned up various manual pages.   (Addresses Debian bug #119624, #120171)
5280
5281Added new translation file for Turkish.
5282
5283Programmer's notes:
5284-------------------
5285
5286Fix general gcc -Wall complaints.
5287
5288E2fsprogs (mostly) works with the dietlibc.
5289
5290The programming texinfo file has been expanded to include description
5291of additional libext2fs functions.  (Still not compeltely done, but a
5292lot of the more important functions have been documented.)
5293
5294Added a umask structure to struct_ext2_filsys, which currently only
5295modifies the behaviour of ext2fs_mkdir(), but if we add any file
5296creation functions to libext2fs, we should also make sure they respect
5297the umask setting.
5298
5299The build-rpm script was fixed to be a bit more safe.
5300
5301The tests' Makefile now has a way of automating test case creation 
5302for e2fsck, using "make testnew".
5303
5304Created a new function, ext2fs_dir_iterate2 which passes more
5305information to the callback function (identical to the one used by
5306ext2fs_dblist_dir_iterate).  The directory iterator functions take a
5307new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5308directory entries.  If the directory entry is deleted, the callback
5309function will be called with the entry paraemter set to
5310DIRENT_DELETED_FILE.
5311  
5312Added new functions, ext2fs_inode_alloc_stats and
5313ext2fs_block_alloc_stats, which takes updates block/inode allocation
5314statistics in the bitmaps, block group descriptors, and superblock
5315when inodes or blocks are allocated or deallocated.
5316
5317
5318E2fsprogs 1.25 (September 20, 2001)
5319===================================
5320
5321This is primarily a bug-fix release; no new features were added, but
5322there are a number of embarassing bug fixes and cleanups applied.
5323
5324Fix a bug mke2fs which causes stack garbage to be written to disk when
5325zapping disk sectors.  (This bug could cause mke2fs to core dump for
5326some kernels, I suspect with security enhancement patches.)
5327
5328Remove unneeded #include of <linux/config.h> which was breaking
5329building e2fsprogs on the Hurd.  (Addresses Debian bug #112414.)
5330
5331Updated tune2fs man page to reflect the fact that adding or removing a
5332journal doesn't require running e2fsck.
5333
5334Remove use of AC_REQUIRE from autoconf which had been used to prevent
5335AC_CANONICAL_HOST from being called twice; unfortunately this causes
5336recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5337used outside of autoconf macros.  Fortunately, it doesn't seem to be
5338necessary any more, anyway.
5339
5340E2fsck will now not fall back to an alternate superblock if the user
5341specifies the superblock location explicitly on the command-line.
5342This allows easier recovery from a situation where the primary
5343superblock and block groups are slightly corrupted, but the backup
5344superblocks are completely broken.  
5345
5346Fix problem which caused compile_et and mk_cmds to blow up if
5347e2fsprogs was in a directory with a pathname that contained spaces.
5348
5349We are now more paranoid about checking the entry in /etc/mtab to make
5350sure the filesystem is really mounted, since some broken distributions
5351(read: Slackware) don't initialize /etc/mtab before checking non-root
5352filesystems.  (Slackware also doesn't check the root filesystem
5353separately, and reboot if the root filesystem had changes applied to
5354it, which is dangerous and broken, but there's nothing I can do about
5355that.)
5356
5357Make UUID library C++ friendly by adding appropriate extern "C"
5358declarations and using const in the function declarations.
5359
5360Fix up the com_err texinfo file so that it can product a valid info
5361file (previously, it could only be used to generate paper
5362documentation using texinfo.tex).
5363
5364
5365E2fsprogs 1.24a (September 2, 2001)
5366===================================
5367
5368Fix brown-paper bug in mke2fs which caused it to segfault when
5369printing the version string.
5370
5371
5372E2fsprogs 1.24 (August 30, 2001)
5373================================
5374
5375Revert the BLKGETSIZE64 support, since for some distributions, this
5376ioctl has been used by an unofficial kernel patch to update the last
5377sector on the disk, and this was causing disk corruption problems as a
5378result.
5379
5380Mke2fs is now more careful about zapping swap space signatures and
5381other filesystem/raid superblock magic values so that programs like
5382mount who try to use hueristics to determine the filesystem type of a
5383partition are less likely to be confused.
5384
5385E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5386regular file (since Andreas Dilger's on-line resizing tools will set
5387its mode bits).
5388
5389Fixed some minor texinfo, man pages nits for spelling errors,
5390texinfo warnings, etc.  (Addresses Debian bug #110621.)
5391
5392E2fsprogs program no longer print the filesystem version number
5393(i.e. 0.5b), since it only confuses people and doesn't serve any real
5394purpose.
5395
5396E2fsck will once again compile under libc5, since it will supply its
5397own version of strnlen if necesssary.
5398
5399mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5400when specifying the external journal device.  tune2fs will also search
5401devices looking for the externla journal debice when removing.  
5402
5403E2fsprogs 1.23 (August 15, 2001)
5404================================
5405
5406Add initial support for extended attributes (EA); e2fsck will
5407correctly handle a filesystem with EA's and check the EA blocks for
5408corruptions.
5409
5410E2fsck's symlink sanity checking has been cleaned up.  It now checks
5411the i_size value of fast symlinks, and checks for immutable flags
5412being set of symlinks, etc.
5413
5414E2fsck now offers to clear inodes which are special files that have a
5415non-zero i_blocks or i_size field.  (The i_size field check was in the
5416previous version of the code, but due to a bug it didn't offer to
5417clear the inode unless i_size and i_size_high were both non-zero.)
5418
5419E2image can now create "raw" image files, which only contain the
5420filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5421debugfs, etc., can be run directly on the raw image file.
5422
5423Add support for the 64-bit block device patches.
5424
5425Fixed bugs in creating external journals with a 1k blocksize.
5426
5427Add initial support for external journals (so long as the external
5428journal only supports a single filesystem) in e2fsck.
5429
5430Remove requirement for needing to run fsck on a filesystem after
5431removing a journal (either internal or external).
5432
5433The man pages now document how to create and manage external journals.
5434
5435Speed up the check of an ext3 filesystems by avoiding a needless flush
5436of all of the superblock and block group descriptors.
5437
5438Speed up creating an internal journal using tune2fs in the case where
5439the filesystem has a lot blocks already allocated.
5440
5441Tune2fs has been fixed to make sure that only error messages go to
5442stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5443
5444Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5445now not set the sparse_super feature.  (Addresses Debian bug #108165)
5446
5447Add support in fsck for the filesystem type "auto".
5448
5449Fsck -A will not try to interpret device names for filesystems which
5450have a pass number is 0.  (Addresses Debian bug #106696).
5451
5452Fsck prints a warning message if now valid filesystems are passed to
5453it.  (Addresses Debian Bug #107458.)
5454
5455E2fsck now gives an explicit warning if there filesystem still has
5456errors at the end of the run. (Addresses Debian bug #104502)
5457
5458E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5459reflects an error.  E2fsck will also not run the orphan list if the
5460filesystem contains errors, since the orphan list might be corrupted.
5461
5462E2fsck now prints the number of large files when given the -v option.
5463
5464Fixed minor memory leaks in e2fsck.
5465
5466Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5467
5468
5469E2fsprogs 1.22 (June 22, 2001)
5470==============================
5471
5472Fixed a bug in e2fsck's handling of orphan inodes which are special
5473files (i.e., block/character device files, named FIFO's, etc.).
5474
5475Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5476tune2fs to fail at adding a journal to a mounted filesystem.
5477
5478Fixed a few big-endian bugs in e2fsprogs
5479	* The directory block functions were accidentally reporting
5480		some directories as corrupted when they weren't.
5481	* If e2fsprogs is compiled --disable-swapfs, the C language 
5482		equivalents weren't being included for big-endian platforms.
5483		(Fixes Debian bug #101686).
5484
5485Fixed a Hurd compilation problem.  (Addresses Debian bug #101361)
5486
5487Programmer's notes:
5488-------------------
5489
5490Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5491ioctls, and allow them to be defined for non-i386 platforms.
5492
5493The uuid.h header file is now protected against multiple inclusions.
5494
5495E2fsprogs is now being developed using BitKeeper.  Changed the test
5496scripts to deal with BK's stripping CR characgters from text files,
5497and changed the top-level Makefile.in to avoid including BitKeeper
5498files when generating the source tarball.
5499
5500
5501E2fsprogs 1.21 (June 15, 2001)
5502==============================
5503
5504Added new configure flags which allow a subset e2fsprogs to be built;
5505this is most useful for boot floopies, since the resulting shared
5506libraries and programs are slimmed down by removing features that
5507aren't necessary for a boot floppy.  The new flags that were added
5508are: --disable-swapfs, which removes support for byte swapping old
5509legacy PPC/68k filesystems, --disable-debugfs, which removes support
5510for debugfs from the libext2fs library, --disable-imager, which
5511removes support for the e2image program, and --disable-resizer, which
5512removes support for resize2fs.
5513
5514E2fsck now prints the number of mounts or days elapsed since the last
5515check when e2fsck is forced to check an otherwise clean filesystem.
5516
5517Tune2fs now prints an informative message about how often a filesystem
5518will be checked when adding a journal to the filesystem, to remind the
5519user that he/she may want to adjust those parameters using tune2fs
5520-c/-i.
5521
5522Worked around hurd brain-damage which causes e2fsck to sometimes
5523believe a filesystem is the root filesystem based on device numbers
5524(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5525violation).
5526
5527Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5528erroneous error with the -F option was specified.
5529
5530Fixed a ext3 recovery bug in the revoke handling; synchronized with
5531ext3 0.7a.
5532
5533Fixed two bugs in e2fsck's handling of dup block handling, dealing
5534with relatively uncommon edge cases: a directory with an indirect
5535block which is claimed by another file, and when the last inode in the
5536filesystem has blocks claimed by another file.
5537
5538E2fsck now checks to see if the i_size field of a fast symlink is too
5539big, and offers to clear the symlink if so.
5540
5541E2fsck now checks to see if i_size_high of special files is non-zero,
5542and offers to clear i_size_high.
5543
5544Fix e2fsck's handling of incompatible journal flags so that the user
5545has chance to abort, and then has the option to clear out the journal
5546entirely.  (Addresses Debian bug #98527.)
5547
5548Fixed a bug in fsck which could cause it to core dump if a mix of
5549standard and non-standard device names are used in /etc/fstab.
5550(Debian bug #100559)
5551
5552Fixed a bug in debugfs which caused read errors when copying a file to
5553not be noticed.
5554
5555The debugfs set_super_value command can now modify the s_lastcheck field.
5556
5557Fixed a bug in lsattr and chattr which was accidentally introduced in
55581.20 to support > 2GB files; both lsattr and chattr wasn't reading
5559directories correctly because the change modified the layout of struct
5560dirent to be incompatible with the libe2p shared library.
5561
5562Cleaned up the mke2fs manual page and included a discussion about why
5563it's good to periodically check the filesystem even when journaling is
5564enabled.
5565
5566Programmer's notes:
5567-------------------
5568
5569Fix general gcc -Wall complaints.
5570
5571The types needed by the ext2 header files are now provided by
5572lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5573
5574Integers are now preferred to longs when trying to find a 32-bit type
5575in ext2_types.h.  Also, if linux/types.h has already been defined,
5576don't try to redefine the types.
5577
5578Fixed make depend script so that it automatically corrects the
5579pathname cleanups performed by make -M, so I don't have to fix them up
5580by hand.
5581
5582Fixed the d_loaddump test case to be more robust, and not depend on
5583bash'isms.
5584
5585Removed debugfs's dependence on pread(), which was accidentally
5586intrudced in e2fsprogs 1.20
5587
5588Fixed a performance bug in the libext2fs's icount routine; the size
5589estimate of the icount array was incorrectly being calculated.
5590
5591Removed use of the badblocks compatibility functions in the e2fsprogs
5592programs.
5593
5594Added paranoia code which protects against strange cases where /etc
5595isn't on the root filesystem, or if /etc/mtab doesn't exist.
5596
5597The header file ext2_types.h is now installed.
5598
5599Autoconf is used to determine when we are on big-endian machines,
5600instead of doing run-time tests, to save a few bytes of code.
5601
5602The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5603functions are no longer inline functions, which saves space and
5604doesn't really cost any real performance.
5605
5606The ext2fs library no longer depends on the e2p library.  (What need
5607there was of it --- namely, fsetflags, was coded in-line).
5608
5609Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5610when the user is stupid and tries compiling the package using "make
5611install" as root.
5612
5613Miscellaneous code cleanups:
5614	* Added missing files from Makefile.in's SRCS file, so that 
5615		their dependencies would be properly calculated.
5616	* Removed redundant code
5617	* Fixed comments in code
5618	* Removed no-longer unneeded argsused #pragma.
5619
5620
5621E2fsprogs 1.20 (May 20, 2001)
5622=============================
5623
5624Add support for replaying the ext3 journal purely in user mode,
5625including handling the orphaned inode list.  Used code contributed by
5626Andreas Dilger, with bug fixes and the orphaned inode handling done
5627by Theodore Ts'o.
5628
5629The mke2fs and tune2fs programs can create or modify a filesystem to
5630include an ext3 journal.  Tune2fs also can be used to remove an ext3
5631journal from a filesystem.
5632
5633E2fsck will now check for the existence of a linked list of orphan
5634inodes in the superblock, and clear those inodes before starting the
5635rest of the filesystem check (but after the journal playback).
5636
5637E2fsck now validates the file descriptor passed to the -C option,
5638which saves against the completion bar getting written to an
5639unexpected location, such as the disk being checked.  (Debian
5640bug/wishlist #55220)
5641
5642E2fsck will now bump the filesystem revision number from zero to one
5643if any of the compatibility bits are set.
5644
5645Fixed a bug where a badly corrupted directory on a big endian system
5646could cause e2fsck to die with a bus error.  The
5647ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5648the ext2 library now does alignment sanity checks on the rec_len field
5649of the directory entry before using it.
5650
5651The ext2 library has been enhanced to make tune2fs safe to run on
5652mounted filesystems.  (Users could usually get away with using tune2fs
5653on mounted filesystems before, but with the advent of ext3 and
5654journaling, it became important to make tune2fs was *really* safe for
5655use even when the filesystem being modified is mounted.)  E2label is
5656now implemented by tune2fs using an argv[0] dispatch, so that e2label
5657is also now safe for use on mounted filesystems.
5658
5659Added a new program, e2image, which creates a backup of critical ext2
5660filesystem data structures.  The generated image file can be examined
5661using dumpe2fs and debugfs.  In the future, e2fsck will be able to use
5662the image file to help recover very badly damaged filesystems.
5663
5664Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5665no longer cause e2fsck to bomb out.  Also treat files > 2GB as being
5666large file when deciding whether or not the filesystem has large files.
5667
5668Fixed lsattr and chattr so that they work correctly on large files.
5669(Fixes Debian bug #72690.)
5670
5671Removed limitation in get_device_size() which imposed a one terrabyte
5672filesystem limitation.  (Most 2.2 kernels still have a signed int
5673problem which cause 1 TB block device limitation.  Fortunately, the
5674kernel patches to fix this are much easier than fixing the 2TB
5675limitation in the kernel.  :-)
5676
5677A max_mount_count of zero is now treated as if no mount count were
5678set.  (Previously, no mount count was indicated by using -1, and a
5679mount count of zero caused e2fsck to always be run.)
5680
5681Mke2fs supports two new filesystem types largefile and largefile4.
5682
5683Mke2fs now adds some randomness in s_max_mount_count so that multiple
5684filesystems won't be all checked at the same time under normal
5685operations.
5686
5687Fixed bug in the progress bar printing code which could cause e2fsck
5688to core dump on an illegal filesystem.
5689
5690Fixed bug in fsck which could allow more than one instance of e2fsck
5691to be printing a progress bar.  (Debian bug #65267)
5692
5693Fsck using a UUID or a LABEL specifier will work even if devfs is
5694compiled into the kernel and not mounted.  If the pathnames in
5695/proc/partitions are incorrect, fsck will search /dev for the correct
5696device (using the new ext2fs_find_block_device library function).
5697Fsck now also checks the RAID devices first so that they are properly
5698found when they are in use.  Support has also been added to support
5699additional IDE disks and the DAC 960 device names.  (Debian bug #94159)
5700
5701Fixed a bug in fsck which caused it not deal properly with 16
5702byte long filesystem labels.
5703
5704Fsck's -t option has been made a lot more flexible.  The semantics for
5705what happens if a comma-separated list to fsck has been regularized,
5706and it is now possible to filter what filesystems will get checked
5707based what is in the filesystem's fstab entry's option field.  (Debian
5708bug #89483.)
5709
5710The dumpe2fs program can now print out the group description
5711information in hex, and also prints the location of the superblock and
5712block group descriptor for those block groups that have them.
5713
5714Mke2fs now clears the ext2 superblock before it starts creating a
5715filesystem, so that the superblock magic number is only written if the
5716filesystem creation process successfully completes.
5717
5718The debugfs program's stat command now pretty-prints the blocks used
5719by an inode so that it's more compact and informative.
5720
5721The debugfs stats command now uses the same libe2p code (which is used
5722by dumpe2fs) to print the superblock header information.  This is more
5723complete, and it avoids a bit of code duplication.
5724
5725Added a new debugfs command, set_super_value (ssv) which allows the
5726user to set arbitrary superblock fields.
5727
5728Debugfs was extended to support inode numbers in hex (by prefixing
5729them with 0x), and so that modify_inode can set the inode generation
5730number.  Also, there is now a new function command called logdump
5731which will dump an ext3 journal.
5732
5733Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5734debugfs.
5735
5736Debugfs's dump command now stops immediately upon reporting a disk
5737read error.  (Fixed a bug in ext2fs_file_read library routine which
5738caused debugfs not to stop.)  (Debian bug #79163)
5739
5740On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5741checked before /etc/mtab is used, since /proc/mounts is more likely to
5742be accurate.
5743
5744Added portability fixes for Solaris and Linux/ia64.
5745
5746Various manual pages were clarified and cleaned up.  (Fixed debian
5747bugs #63442, #67446, and #87216)
5748
5749
5750Programmer's notes:
5751-------------------
5752
5753The e2fsck message printer now supports %Iu and %Ig, which will print
5754out the inode's user and group owners, respectively.
5755
5756E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5757that no longer dependent on the system having the correct version of
5758the kernel header files.
5759
5760Added a new function to libext2, ext2fs_find_block_device(), which
5761searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5762device given its device number.
5763
5764Added a new function to libext2, ext2fs_sync_device, which centralizes
5765all of the places which might try to use the BLKFLSBUF or FDFLUSH
5766ioctls (and usually failing to define them since the system header
5767files don't usually do this for us, and we're trying to avoid usage of
5768kernel include files now).
5769
5770Added new utility programs in tests/progs: random_exercise and
5771hold_inode.  They aren't built by default; they're useful for
5772exercising ext3 filesystem code.
5773
5774Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5775the filesystem close functions to only update the superblock, and to
5776not touch the block group descriptors.  Needed by tune2fs when
5777modifying a mounted filesystem.
5778
5779Got rid of struct ext2fs_sb and replaced it with the standard struct
5780ext2_super_block from include/linux/ext2_fs.h.  Note: this may break
5781source (but not binary) compatibility of some users of the ext2
5782library.  Those applications should just simply do a global search and
5783replace of struct ext2fs_sb with struct ext2_super_block, and include
5784the new header file <ext2fs/ext2_fs.h> which defines it.
5785
5786The ino_t type has been renamed ext2_ino_t to protect applications
5787that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5788inexplicably changes ino_t(!?).  So we use ext2_ino_t to avoid an
5789unexpected ABI change.
5790
5791The Makefiles have been reworked so that "make check" can be run from
5792the top-level Makefile.
5793
5794Fix general gcc -Wall complaints and removed dead code.
5795
5796Remove use of NOARGS, because we assume everyone does ANSI C these
5797days.
5798
5799Added build-rpm script from sct.
5800
5801New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 
5802to support e2image.
5803
5804New function ext2fs_flush_icache which must be called if the
5805application program modifies the inode table blocks without going
5806through ext2fs_write_inode() interface.
5807
5808New ext2fs_check_mount_point() function, which will return the mount
5809point of a device if mounted.
5810
5811The io_channel abstraction now has an optional interface,
5812io_channel_write_range, which allows specific byte ranges to be
5813written.  
5814
5815The unix_io IO channel now supports write-through caching, so that
5816journal creation is more efficient.
5817
5818Added x86 assembly language routines to support byte swapping, to
5819reduce executable size.
5820
5821Fixed bug in the utility program subst so that it's possible to
5822replace a substitution variable with a zero-length string.
5823
5824Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5825slipped into some of the problem number.
5826
5827E2fsprogs 1.19 (July 13, 2000)
5828==============================
5829
5830Release the resize2fs program since the timeout before it could
5831be released under the GPL has finally expired.
5832
5833Add experimental support needed for the ext2 compression patches.
5834This requires compiling e2fsprogs with the --enable-compression flag
5835to the configure script.
5836
5837Added ext3 journalling support.  E2fsck will run the journal (if
5838necessary) by temporarily mounting the filesystem.  /sbin/fsck.ext3 is
5839installed as a symlink to e2fsck.  Fsck has been taught about ext3,
5840and treats it the same as ext2 in terms of the progress bar logic.
5841Dumpe2fs will display the superblock journaling information if the
5842filesystem has a journal.  The ext2 library will now permit opening an
5843ext3 filesystem with the recovery flag set.  This is necessary for
5844on-line dump's to work correctly, but there may be issues with this
5845working well since ext3 is much less agressive about syncing blocks to
5846the filesystem, since they're safe on the journal.
5847
5848Tune2fs and e2fsck have been changed to allow the mount_count check to
5849be disabled by setting max_mount_count to -1.  (This was already
5850supported by the kernel.)
5851
5852Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5853are used for ext3 as well.
5854
5855Added internationalization support for e2fsprogs; must be enabled
5856by passing --enable-nls to configure.
5857
5858Always use the provided ext2fs header files to insulate ourselves from
5859kernel version changes.  Which include files are used by e2fsprogs
5860have also been cleaned up to improve portability.
5861
5862Limit the number of times that e2fsck updates the progress bar so that
5863people who are booting using a 9600 baud console don't get swampped by
5864too many updates.
5865
5866Improved the loop detection algorithm in e2sck's pass #3 so that it is
5867much, much faster for large filesystems with a large number of
5868directories.
5869
5870The memory footprint for e2fsck is now slightly smaller than before.
5871
5872E2fsck now checks if special devices have a non-zero size, and offers
5873to clear the size field if it finds such an inode.  
5874
5875E2fsck now checks if special devices have the append-only flag set,
5876and offers to clear the inode.
5877
5878E2fsck now properly handles some "should never fail" cases during a
5879bitmap copy in pass5.
5880
5881E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5882
5883E2fsck now calculates the correct location of the backup superblock in
5884the case of filesystem blocksizes > 1k.
5885
5886Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5887which normally didn't cause problems under most filesystem parameters,
5888but could cause a valid superblock to be rejected in extreme cases.
5889Other checks for validating superblock values were made more
5890stringent.
5891
5892Added non-destructive write testing to the badblocks program, courtesy
5893of David Beattie.  The badblocks also now has an option to input the
5894current set of bad blocks, so that known bad blocks are skipped to
5895speed up the badblocks test.  There is also a persistent rescan
5896feature which causes badblocks to run until it has completed some
5897number of passes without discovering any new bad blocks.
5898
5899Badblocks now checks to see if the device is mounted and refuses to do
5900the tests involving writing to the device if it is mounted.  Also,
5901badblocks now allows the number of blocks to be checked to be
5902defaulted to the size of the partition.
5903
5904Fixed a bug in fsck which didn't allow non-root users to be able to
5905check filesystems if there were any LABEL= or UUID= entries in
5906/etc/fstab.
5907
5908The Hurd doesn't support the filetype filesystem feature.  The mke2fs
5909program now makes sure that for the Hurd, the filestype feature is
5910turned off.  E2fsck will check to see if the filetype feature is
5911turned on for Hurd filesystems, and offer to turn off the feature.
5912
5913Mke2fs now has a safety check to make sure the number of blocks do not
5914exceed 32 bits even on a 64 bit platform.
5915
5916Really fixed a bug in fsck to allow "fsck -As" to run interactive
5917fsck's.  (For those people who like to do interactive fsck's in the
5918/etc/rc scripts!?!)
5919
5920Debugfs has a few new features: the rdump command, which will do a
5921recursive dump of a directory and all of its contents, and the lcd
5922command which does a local chdir (much like the ftp command of the
5923same name).  In addition, the debugfs program and the open_filesystem
5924command now takes three new options: -b and -s, which allows the
5925blocksize and superblock location to be specified, and the -c option
5926which is used in catastrophic situations where the block group
5927descriptors are corrupt.  If the -c option is specified, debugfs will
5928skip trying to read in the block and inode bitmaps.
5929
5930Debufs's lsdel command was fixed to handle bad blocks in the inode
5931table.
5932
5933A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
59344 digit years.
5935
5936General improvements in error messages
5937
5938  - Mke2fs prints a sane error message if the partition size is zero
5939	(usually because the partition table wasn't reread by the
5940	kernel due to the partition being busy), instead of "invalid
5941	argument passed to ext2 library while initializing superblock".
5942
5943  - Fsck now prints more self-explanatory message if an invalid UUID=
5944	or LABEL= specification is passed to it.
5945
5946UUID library changed to use the LGPL.
5947
5948Fixed a bug in the UUID library where very rapid calls to the
5949time-based UUID generator could cause duplicate UUID's to be returned.
5950This was not a problem for e2fsprogs, but it could be a problem for
5951other users of the library.
5952
5953Make the UUID library more robust in the face of missing or an
5954improper /dev/urandom or /dev/random files.
5955
5956Added some random portability fixes for Solaris.
5957
5958Some minor man page updates.
5959
5960Fixed a memory leak in the ss library.
5961
5962
5963Programmer's notes:
5964-------------------
5965
5966We now try to use lseek64 and open64 from the LFS if possible.
5967
5968The 3rd parameter in e2p's print_flags is now a flags word, instead of
5969a boolean option.
5970
5971The mark and unmark bitmap functions now return the previous state of
5972the bit that was being changed, which is useful for some speed
5973optimizations.
5974
5975The following functions have been added to enhance the badblocks list
5976handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5977ext2fs_badblocks_equal.
5978
5979The ext2 header files now have the latest journalling fields to the
5980superblock.
5981
5982The ext2fs_mkdir function in libext2fs now properly backs out of error
5983conditions robustly.
5984
5985Cleaned up makefiles:
5986  - to cleanly  compile with the -j flag.
5987  - so distclean removes all generated files.
5988  - so in case of an error while installing header files, the make aborts.
5989
5990Fix test_script so that it works correctly when compiling in the
5991source directory.
5992
5993The random UUID generation routine has been made slightly better in
5994the case where /dev/random doesn't exist.  (Use of randomly-based UUID
5995is still not recommended if /dev/random doesn't exist, however; it's
5996better to use the time/ethernet MAC address UUID in this case.)
5997
5998Clean up the build process so it's more friendly in case of missing
5999directories.
6000
6001The ext2fs header file can now be #include'd into C++ programs.
6002
6003The e2p.h header file is now installed.
6004
6005Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
6006
6007
6008
6009E2fsprogs 1.18 (November 10, 1999)
6010==================================
6011
6012Fix a core dumping bug in e2fsck if an imagic inode is present or
6013(more rarely) if the filesystem is badly corrupted enough that e2fsck
6014has to restart pass 1 processing.  E2fsck now closes the filesystem
6015before freeing a large number of its data structures, so in the case
6016of future memory faults, at least the fixed filesystem will be fully
6017written out.
6018
6019If a filesystem doesn't support imagic inodes, and e2fsck discovers an
6020imagic inode, it will offer to clear the imagic flag.
6021
6022E2fsck will now offer to clear the immutable flag on special files
6023(device/socket/fifos) when running it in non-preen mode.
6024
6025E2fsck will now set the filetype when creating /lost+found, and when
6026connected orphaned inodes to /lost+found.
6027
6028Debugfs's ncheck and icheck commands now handles the case where there
6029are bad blocks in the inode table without bombing out.
6030
6031The badblocks list processing code has been made more efficiently for
6032appending a large number of (ordered) badblocks to the badblocks list.
6033
6034Some minor man page updates.
6035
6036Fsck now allows interactive e2fsck's when using fsck -As (not a common
6037mode, but some people like to do this in boot scripts for silly reasons).
6038
6039Programmer's notes:
6040-------------------
6041
6042The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
6043with the problem code convention.
6044
6045The badblocks list regression test program has been updated to work
6046with previously made API name changes.
6047
6048The ext2fs_free() command now uses the new badblocks API to avoid
6049using the compatibility layer.
6050
6051Added new regression test cases; the run_e2fsck test script now
6052supports the ability for a test case to run a prepratory command
6053before running e2fsck.
6054
6055E2fsprogs 1.17 (October 26, 1999)
6056=================================
6057
6058Fixed nasty typo in fsck which caused parallelized fsck's to go into an
6059infinite loop.
6060
6061Fixed a bug in fsck where it used strncmp to compare a binary UUID,
6062thus potentially causing problems if a binary UUID contained a NULL
6063character.
6064
6065E2fsck now uses stricter checks for directory entries in pass 2:
6066zero-length filenames are not allowed; neither are 8 byte long
6067directory entries.
6068
6069The debugfs "dirty" command now clears the filesystem valid bit.
6070(Previously this just set the dirty-as-in-needs-writing-out-to-disk
6071bit in the in-core superblock image.  The new functionality is more
6072what the user expects, and is more useful.)
6073
6074Added a debugging hook to test parallel fsck; if the environment
6075variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
6076will be checked in parallel when they normally would not be.
6077
6078Programmer's notes:
6079-------------------
6080
6081Fixed some #ifdef's for compilation under the Hurd OS.
6082
6083Fixed minor W2K compatibility problems.
6084
6085Fixed some miscellaneous GCC warnings.
6086
6087
6088E2fsprogs 1.16 (October 22, 1999)
6089=================================
6090
6091Fixed a race condition bug in fsck; when printing a progress bar, if
6092checking multiple filesystems in parallel, it was possible for fsck to
6093send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
6094handler, which would cause it to terminate with a signal 10.
6095
6096E2fsck now properly handles filesystems that have the
6097INCOMPAT_FILETYPE feature turned on.  It can be used to convert a
6098filesystem into using or not using FILETYPE feature.
6099
6100E2fsck now properly handles filesystems that have the IMAGIC feature
6101turned on (this is used on Linux AFS servers).
6102
6103The mke2fs program now creates filesystems that have the filetype and
6104sparse_superblock features enabled by default, unless it is run on a
6105pre-2.2 kernel.  These features are not supported by a pre-2.2 kernel,
6106so there is now a new flag -O which allows the user to specify with
6107which features she would like to create the filesystem; "mke2fs -O
6108none" will create a filesystsem compatible with 2.0 kernels.
6109
6110The tune2fs program now has a -O option which allows the user to set
6111and reset "safe" filesystem features.  Currently, the only ones which
6112allows to be modified are the filetype and sparse_superblock features.
6113Note setting or clearing either feature will require running e2fsck on
6114the filesystem afterwards.  (n.b. Clearing the sparse_superblock feature
6115requires that there is enough free space on the filesystem for the
6116extra superblocks which will be created by e2fsck.)
6117
6118Debugfs can now set and print filesystem features in the superblock
6119using the "features" command.  Dumpe2fs will print out the complete
6120set of features when listing the superblock.
6121
6122Dumpe2fs has new options -f (force) and -h (header-only).
6123
6124Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
6125message to come up.  This could happen when decrementing or
6126incrementing a link count could result in an overflow.
6127
6128Fixed a bug in e2fsck where the block count on the lost+found
6129directory would not be properly incremented when the directory was
6130expanded to the point where an indirect block needed to be allocated.
6131
6132E2fsck now makes some additional sanity checks on the superblock to
6133avoid crashing or giving a memory allocation error if some of the
6134values in the superblock are unresonable (but the superblock otherwise
6135looks valid).
6136
6137Fixed a bug in e2fsck where a very badly corrupted filesystem might
6138require two passes to completely fix the filesystem.  This happened if
6139an inode claimed blocks that was part of the filesystem metadata
6140(typically, when garbage was written into an inode table or indirect
6141block, since this kind of filesystem corruption normally doesn't
6142happen otherwise).
6143
6144On the Alpha, glibc declares st_flags although it isn't actually used;
6145the configure script was improved to detect this case so that
6146e2fsprogs can avoid using the non-functional stat field.
6147
6148The manual pages were updated to use a more consistent formatting
6149style consistent with standard Unix man pages.  Mke2fs's man page
6150added documentation for a few previously undocumented options.
6151
6152Fixed minor display bugs in tune2fs and mke2fs.
6153
6154Programmer's notes:
6155-------------------
6156
6157Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6158
6159Added features to parse and print feature strings into the e2p library.  
6160(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6161
6162ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6163whose directory entries contain proper filetype information if the
6164filesystem supports it.
6165
6166ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6167the directory entry filetype information.  This is used to set the
6168directory entry filetype information if the filesystem supports it.
6169
6170Fixed a bug in ext2fs_expand_dir() where the block count in a
6171directory's inode would not be properly incremented when the directory
6172was expanded to the point where an indirect block needed to be
6173allocated.
6174
6175
6176E2fsprogs 1.15 (July 18, 1999)
6177==============================
6178
6179Add configuration checks so that e2fsprogs will compile cleanly on
6180Linux 2.3 kernels that have renamed i_version to i_generation.
6181
6182E2fsck now prints a progress/completion bar (and not just a simple
6183spinner) if the -C0 option is requested or if it receives a SIGUSR1
6184signal.  Fsck will automatically manage the (potentially muliple)
6185e2fsck processes to print completion bars if it is given a -C option,
6186with the right thing happening if multiple filesystems are being
6187checked in parallel.
6188
6189Mke2fs now has better automatic hueristics to determine the filesystem
6190parameters to be used for a particular filesystem.  Added a new option
6191-T which allows the user to specify how the filesystem is to be used,
6192which helps mke2fs do a better job selecting the filesystem parameters.
6193
6194Mke2fs now creates revision 1 filesystems by default, and with the
6195sparse superblock feature enabled.  The sparse superblock feature is
6196not understood by Linux 2.0 kernels, so they will only allow read-only
6197mounts of filesystems with this sparse superblocks.
6198
6199Fix bug where if /dev/null couldn't be opened (should never happen),
6200e2fsck would hang in a tight loop.
6201
6202Make e2fsck handle the case where /lost+found isn't a directory.
6203
6204E2fsck now uses mallinfo if it exists to get accurate statistics about
6205its memory usage.
6206
6207Fix bug in e2fsck where it wouldn't check to see if a disconnected
6208inode had any problems before connecting it to /lost+found.
6209
6210Add check to e2fsck so it makes sure that total number of inodes in
6211the filesystem is a sane number.
6212
6213Fix fencepost error when clearing an the end of the block bitmap which
6214caused the last block in the bitmap not to get cleared.
6215
6216Cleaned up a number of messages in e2fsck:
6217	* The message "Group's #'s copy of the group descriptor..."
6218		was fixed so that the correct number would be displayed.
6219	* Added missing space in the "disk write-protected" error messsage
6220	* Cleaned up the error message printed when a non-interactive
6221		e2fsck needs to abort a check because the filesystem
6222		appears to be mounted.
6223
6224Added a new command-line utility, uuidgen, which will create and print
6225a UUID.
6226
6227Make debugfs's icheck command more robust by checking to make sure an
6228inode has valid blocks before interarting over the inode's blocks.
6229
6230UUID generation now uses a random-based scheme whenever possible to
6231prevent potential privacy problems.
6232
6233Man pages for all of the UUID functions in the lirbary were added.
6234
6235Fixed bug in fsck so it won't coredump if a filesystem not in
6236/etc/fstab is given to it.
6237
6238Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6239that most of the other mount utilities understands.
6240
6241Mke2fs will make a filesystem even if it appears mounted if the force
6242option is given.
6243
6244Dumpe2fs has new command-line options which allow a filesystem expert
6245to specify the superblock and blocksize when opening a filesystem.
6246This is mainly useful when examining the remains of a toasted
6247filesystem.
6248
6249The badblocks program has been updated to display correctly on disks
6250with large block numbers.
6251
6252The badblocks program no longer gives spurious errors when errors
6253occur on non-block boundaries, which is common if the blocksize is
6254larger than 1k.
6255
6256Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6257MKE2FS_SYNC environment variable is set.  This is to work around a VM
6258bug in the 2.0 kernel.  I've heard a report that a RAID user was able
6259to trigger it even using a 2.2 kernel, but hopefully it will not be
6260needed for most Linux 2.2 users.
6261
6262Fixed miscellaneous documentation and man pages.
6263
6264Programmer's notes:
6265-------------------
6266
6267Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6268in e2fsck's pass1.c really should have been static.
6269
6270The return value of the uuid_compare() function was changed to make it
6271match with the convetions used by strcmp, memcmp, and Paul Leach's
6272UUID sample document.
6273
6274The "make depend" process has now been made more automated; it now
6275automatically word-wraps the dependencies, and only replaces source
6276Makefile.in if there has been a change in the dependencies.  Also, a
6277top-level "make depend" now recurses through all the subdirectories
6278automatically.
6279
6280The Makefile in .../util has been changed so that subst is built using
6281the native C compiler during a cross-compilation, since the subst
6282program is only used during the build process.  Also add an explicit
6283rule to build util/subst by cd'ing to the correct directory and
6284running Makefile.
6285
6286The man directories are defined in terms mandir, so that the configure
6287script can override the location of the manual pages.
6288
6289The config files have been updated to recognize new machine types for
6290both the i386 and alpha families.
6291
6292Fsck has been modified so that it will accurately create an
6293fsck_instance even when the noexecute flag is set.  This allows for
6294accurate debugging of the fsck pass structure.  Also, when the verbose
6295flag is given twice, fsck will print debugging information about when
6296fsck is waiting for jobs to finish.
6297
6298
6299E2fsprogs 1.14 (January 9, 1999)
6300================================
6301
6302Fix the fstab parsing code so that it can handle blank lines and
6303comment characters.  Also, missing pass numbers need to be treated as
6304zero.
6305
6306Fixed a bug in e2fsck where under some circumstances (when e2fsck
6307needs to restart processing after fixing an egregious inconsistency)
6308it would try to access already freed memory.
6309
6310E2fsck now prints non-printable characters in directory entries and
6311pathnames using '^' and 'M-' notation.
6312
6313Fixed chattr so that it will ignore symbolic links when doing
6314recursive descent traversals.  For both chattr and lsattr, no longer
6315print the version string unless the -V option is given.
6316
6317Allow the system administrator to directly specify the number of
6318inodes desired in the filesystem, for some special cases where this is
6319necessary.
6320
6321Fix portability problems so that e2fsprogs can be compiled under Linux
63221.2 systems and Solaris systems.
6323
6324Update the config.guess file with a more recent version that will
6325identify newer Linux platforms.
6326
6327Programmer's notes
6328------------------
6329
6330Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6331an inode number of zero is passed to them.
6332
6333E2fsprogs 1.13 (December 15, 1998)
6334==================================
6335
6336Fixed a bug in debugfs where an error messages weren't getting printed
6337when the ext2 library routines to read inodes returned errors in the
6338stat, cmri and rm commands.
6339
6340Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6341provided, it won't create an inode table smaller than the minimum
6342number of inodes required for a proper ext2 filesystem.
6343
6344Fsck now parses the /etc/fstab file directly (instead of using
6345getmntent()), so that it can distinguish between a missing pass number
6346field and pass number field of zero.  This caused problems for
6347diskless workstations where all of the filesystems in /etc/fstab have
6348an explicit pass number of zero, and fsck could not distinguish this
6349from a /etc/fstab file with missing pass numbers.
6350
6351E2fsck will create a /lost+found directory if there isn't one in the
6352filesystem, since it's safer to create the lost+found directory before
6353it's needed.
6354
6355Fixed e2fsck so that it would detect bogus immutable inodes which
6356happen to be sockets and FIFO files, and offer to clear them.
6357
6358If a filesystem has multiple reasons why it needs to be checked, and
6359one of the reasons is that it is uncleanly mounted, e2fsck will print
6360that as the reason why the filesystem is being checked.
6361
6362Cleaned up the output routines of mke2fs so that it doesn't overflow
6363an 80 column display when formating really big filesystems.
6364
6365Added a sanity check to e2fsck to make sure that file descriptors 0,
63661, 2 are open before opening the hard disk.  This avoids a problem
6367where a broken program might exec e2fsck with those file descriptors
6368closed, which would cause disastrous results if the kernel returns a
6369file descriptor for the block device which is also used by FILE *
6370stdout.
6371
6372Fixed up the e2fsck progress reporting functions so that the values
6373reliably reach 100% at the completion of all of the e2fsck passes.
6374
6375Fixed minor documentation bugs in man pages and usage messages.
6376
6377Programmer's notes:
6378-------------------
6379
6380Fixed a number of lint warnings in the ext2fs library and potential
6381portability problems from other OS's header files that might define
6382CPP macros for names like "max" and "min".
6383
6384ext2fs_badblocks_list_add() has been made more efficient when it needs
6385to grow the bad blocks list.
6386
6387Fixed a bug in e2fsck which caused it to dereference a freed pointer
6388just before exiting.
6389
6390Fixed the substition process for generating the mk_cmds and compile_et
6391scripts so that they will work outside of the build tree.
6392
6393Add sanity check to e2fsck so that if an internal routine
6394(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6395and causing a core dump.  This should never happen, but...
6396
6397E2fsprogs 1.12 (July 9, 1998)
6398==================================
6399
6400E2fsprogs now works with glibc (at least with the version shipped wtih
6401RedHat 5.0).  The ext2fs_llseek() function should now work even with
6402i386 ELF shared libraries and if llseek() is not present.  We also
6403explicitly do a configure test to see if (a) llseek is in libc, and
6404(b) if llseek is declared in the system header files.  (See standard
6405complaints about libc developers don't understand the concept of
6406compatibility with previous versions of libc.)
6407
6408The ext2fs library now writes out the block group number in each of
6409the superblock copies.  This makes it easier to automatically
6410determine the starting block group of the filesystem when the block
6411group information is trashed.
6412
6413Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6414which means that e2fsprogs will ignore the high 8 bits of the
6415directory entry's name_len field, so that it can be used for other
6416purposes.
6417
6418Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6419E2fsprogs will now support filesystems with 64-bit sized files.
6420
6421Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6422
6423Added new program "e2label", contributed by Andries Brouwer.  E2label
6424provides an easy-to-use interface to modify the filesystem label.
6425
6426Fixed bug so that lsattr -v works instead of producing a core dump.
6427
6428Fixed a minor bug in mke2fs so that all groups with bad superblock
6429backup blocks are printed (not just the first one).
6430
6431Mke2fs will check the size of the device, and if the user specifies a
6432filesystem size larger than the apparent size of the device it will
6433print a warning message and ask if the user wants to proceed.
6434
6435E2fsck has a new option -C, which sends completion information to the
6436specified file descriptor.  For the most part, this is intended for
6437programs to use, although -C 0 will print a spinning character to the
6438stdout device, which may be useful for users who want to see something
6439happening while e2fsck goes about its business.
6440
6441Fixed a bug in e2fsck which could cause a core dump when it needs to
6442expand the /lost+found directory, and sometimes the bitmaps haven't
6443been merged in.  Also fixed a related bug where ext2fs_write_dir_block
6444was used to write out a non-directory block.  (Which would be bad on a
6445non-Intel platform with byte swapping going on.)
6446
6447Fixed bug in e2fsck where it would print a "programming error" message
6448instead of correctly identifying where a bad block was in used when
6449the bad block was in a non-primary superblock or block group
6450descriptor.  Also fixed a related bug when sparse superblocks are in
6451use and there is a bad block where a superblock or block group
6452descriptor would have been in a group that doesn't include a
6453superblock.
6454
6455Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6456the block group descriptor table is corrupt, it was possible to try to
6457allocate a huge array, fail, and then abort e2fsck.
6458ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6459and subsitutes reasonable values if the descriptors are obviously bogus.
6460
6461If e2fsck finds a device file which has the immutable flag set and the
6462i_blocks beyond the normal device number are non-zero, e2fsck will
6463offer to remove it, since it's probably caused by garbage in the inode
6464table.
6465
6466When opening a filesystem, e2fsck specially checks for the EROFS error
6467code, and prints a specific error message to the user which is more
6468user friendly.
6469
6470If the filesystem revision is too high, change the e2fsck to print
6471that this is either because e2fsck is out of date, or because the
6472superblock is corrupt.  
6473
6474E2fsck now checks for directories that have duplicate '.' and '..'
6475entries, and fixes this corruption.
6476
6477E2fsck no longer forces a sync of the filesystem (with attendant sleep
6478calls) at all times.  The ext2fs_flush() function now performs a sync
6479only if it needed to write data blocks to disk.
6480
6481Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6482certain errors would not be properly reported.
6483
6484Updated and expanded a few points in the man pages which users
6485complained wheren't explicit enough.
6486
6487Added special case byte-swapping code if compiling on the PowerPC, to
6488accomodate the strange big-endian variant of the ext2 filesystem that
6489was previously used on the PowerPC port.
6490
6491
6492Programmer's notes:
6493-------------------
6494
6495Removed C++ keywords from the ext2fs libraries so that it could be
6496compiled with C++.
6497
6498E2fsck's internal organization has now been massively reorganized so
6499that pass*.c don't have any printf statements.  Instead, all problems
6500are reported through the fix_problem() abstraction interface.  E2fsck
6501has also been revamped so that it can be called as a library from a
6502application.
6503
6504Added new fileio primitives in libext2fs for reading and writing
6505files on an unmounted ext2 filesystem.  This interface is now used by
6506debugfs.
6507
6508Added a new libext2fs function for mapping logical block numbers of
6509a file to a physical block number.
6510
6511Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6512a block, zeros it, and updates the filesystem accounting records
6513appropriately.
6514
6515Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6516sets the padding of the bitmap to be all one's.  Used by e2fsck pass 5.
6517
6518The libext2fs functions now use a set of memory allocation wrapper
6519functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6520instead of malloc, free, and resize.  This makes it easier for us to
6521be ported to strange environments where malloc, et. al. aren't
6522necessarily available.
6523
6524Change the libext2fs fucntion to return ext2-specific error codes
6525(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6526and depending on the existence of system error codes (such as EEXIST
6527and ENOENT).
6528
6529Renamed io.h to ext2_io.h to avoid collision with other OS's header
6530files.
6531
6532Add protection against ext2_io.h and ext2fs.h being included multiple
6533times.
6534
6535The types used for memory lengths, etc. have been made more portable.
6536In generla, the code has been made 16-bit safe.  Added Mark
6537Habersack's contributed DOS disk i/o routines.
6538
6539Miscellaneous portability fixes, including not depending on char's
6540being signed.
6541
6542The io_channel structure has a new element, app_data, which is
6543initialized by the ext2fs routines to contain a copy of the filesystem
6544handle.
6545
6546ext2fs_check_directory()'s callback function may now return the error
6547EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6548really do the checking, despite the presence of the callback function.
6549
6550
6551E2fsprosg 1.11 (June 17, 1997)
6552==============================
6553
6554Fixed e2fsck to detect (previously ignored) conflicts between the
6555superblock or block group descriptors and block bitmaps, inode
6556bitmaps, and inode tables.
6557
6558Fixed bug in e2fsck so that when the message printed out when a block
6559or inode bitmap conflicts with other data, it has the correct group
6560number.
6561
6562Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6563to badblocks.  This meant that not all of the filesystem was being
6564tested for bad blocks! 
6565
6566Fixed an array boundary overrun case which cropped up in
6567ext2fs_badblocks_list_test when a user tried running "mke2fs -c 
6568-b 4096".
6569
6570Adjusted the number of columns printed by mke2fs when displaying the
6571superblock backups to avoid running over 80 columns when making a
6572really big filesystem.
6573
6574Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6575dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6576fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6577
6578Programmer's notes:
6579-------------------
6580
6581Fixed install rule in lib/ss so that ss_err.h is actually getting
6582installed.
6583
6584Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6585bassed back to the caller.
6586
6587Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6588setting the current inode number (which meant this function wasn't
6589working at all).
6590
6591Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6592blocks in the bitmap when increasing the size of the bitmap.
6593
6594Changed the initial number of blocks allocated by ext2fs_init_dblist()
6595to be more realistic.
6596
6597Added a new function ext2fs_allocate_group_table, which sets up the
6598group descriptor information (and allocates inode and block bitmaps,
6599and inode tables for a particular group).  The function was created by
6600factoring out code form ext2fs_allocate_tables().
6601
6602Added a new function ext2fs_move_blocks which takes a bitmap of the
6603blocks to be moved, and moves them to another location on the
6604boardboard.
6605
6606Make the unix_io channel's io_channel_flush implementation calls sync()
6607to to flush the kernel buffers to disk.
6608
6609Added a new function ext2fs_dblist_count returns the number of
6610directory blocks in dblist.
6611
6612
6613E2fsprogs 1.10 (April 24, 1997)
6614===============================
6615
6616Mke2fs once again defaults to creating revision #0 filesystems, since
6617people were complaining about breaking compatibility with 1.2 kernels.
6618Warning messages were added to the mke2fs and tune2fs man pages that
6619the sparse superblock option isn't supported by most kernels yet (1.2
6620and 2.0 both don't support parse superblocks.)
6621
6622Added new flag to mke2fs, -R <raid options>, which allows the user to
6623tell mke2fs about the RAID configuration of the filesystem.  Currently
6624the only supported raid option is "stride" which specifies the width
6625of the RAID stripe.
6626
6627Fixed bug in e2fsck where pass1b would bomb out if there were any
6628blocks marked bad in the inode table.
6629
6630Fixed rare bug in mke2fs where if the user had a very unlucky number
6631of blocks in a filesystem (probability less than .002) the resulting
6632filesystem would be corrupt in the last block group.
6633
6634Fixed bug where if e2fsck tried to allocate a block to fix a
6635filesystem corruption problem and the filesystem had no free blocks,
6636ext2fs_new_block() would loop forever.
6637
6638The configure script now checks explicitly to see if "-static" works,
6639since that can't be assumed to be true --- RedHat doesn't install
6640libc-static by default.
6641
6642Fixed bug in libext2's block iterator functions where under some
6643cirmcustances, file with holes would cause the bcount parameter to the
6644callback function to be incorrect.  This bug didn't affect any of
6645e2fsprogs programs, but it was discovered by Paul Mackerras, the
6646author of the PPC boot loader.
6647
6648Removed use of static variables to store the inode cache in libext2fs.
6649This caused problems if more than one filesystem was accessed via
6650libext2fs (static variables in libraries are generally a bad idea).
6651Again, this didn't affect e2fsprogs programs, but it was discovered by
6652Paul Mackerras.
6653
6654Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6655will compile cleanly with 1.2.13 kernels (even with a.out shared
6656libraries!)
6657
6658Programmer's notes:
6659-------------------
6660
6661Added new functions to duplicate an ext2 filesystem handle, and its
6662associated substructure.  New functions: ext2fs_dup_handle(),
6663ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6664Other structures, such as the io_channel and the inode_cache, now have
6665a ref count so that they only get freed when they are no longer used
6666by any filesystem handle.  (These functions were added as part of the
6667development effort for an ext2 resizer).
6668
6669E2fsprogs 1.09 (April 14, 1997)
6670===============================
6671
6672Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6673accidentally introduced in the 1.08 release.  The overhead calculation
6674was accidentally removed, which caused ext2fs_initialize() to not
6675notice when the filesystem size needed to be adjusted down because
6676there wasn't enough space in the last block group.
6677
6678Fixed bug in version parsing library routine; it was always parsing
6679the library version string, instead of using the passed-in string.
6680
6681Clarified chattr man page.
6682
6683E2fsprogs 1.08 (April 10, 1997)
6684===============================
6685
6686E2fsck 1.07 was very slow when checking very large filesystems with a
6687lot of files that had hard links (i.e., news spools).  This was fixed
6688by seriously revamping the icount abstraction.  Added a formal test
6689suite for the icount abstraction.
6690
6691Debugfs now has a "-l" option to the "ls" command, which lists the
6692inode number, permissions, owner, group, size, and name of the files
6693in the directory.
6694
6695Fix a bug in e2fsck where when a directory had its blocks moved to
6696another location during the pass 1b processing, the directory block
6697list wasn't updated, so pass 2 wouldn't check (and correct) the
6698correct directory block.
6699
6700E2fsck will now treat inodes which contain blocks which are claimed by
6701the filesystem metadata by treating them as multiply claimed blocks.
6702This way, the data in those blocks can be copied to a new block during
6703the pass 1b--1d processing.
6704
6705E2fsck will attempt to determine the correct superblock number and
6706display it in the diagnostic and warning messages if possible.
6707
6708Add support for a new (incompatible) feature, "sparse_super".  This
6709feature reduces the number of blocks which contain copies of backup
6710superblocks and block group descriptors.  (It is only an incompatible
6711feature because of a bug in ext2_free_blocks.)  mke2fs and tune2fs now
6712support a new -s option; e2fsck will recognize filesystems built with
6713this feature turned on.
6714
6715E2fsck now checks the library to make sure is the correct version,
6716using new library functions.  (This helps to diagnose incorrectly
6717installed e2fsprogs distributions.)
6718
6719Dumpe2fs now prints more information; its now prints the the
6720filesystem revision number, the filesystem sparse_super feature (if
6721present), the block ranges for each block group, and the offset from
6722the beginning of the block group.
6723
6724Mke2fs now distributes the inode and block bitmap blok so that the
6725won't be concentrated in one or two disks in RAID/striping setups.
6726Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6727choose the largest blocks per group that be chosen.  (For 2k blocks,
6728you can have up to 16384 blocks/group; for 4k blocks, you can have up
6729to 32768 blocks/group.)  Previously mke2fs would not allow
6730specification of more than 8192 blocks per group, even if you were
6731using a 2k or 4k block group.
6732
6733Programmer's notes:
6734-------------------
6735
6736Added a new function ext2fs_create_icount2() which takes a "hint"
6737argument.  This hint argument presets the icount array with the list
6738of inodes which actually need to be in the icount array.  This really
6739helps to speed up e2fsck.
6740
6741Added a new function ext2fs_icount_validate() which checks the rep
6742invariant for the icount structure.  This is used mostly for testing.
6743
6744The error mesasage given when a bad inode number is passed to
6745test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6746EXT2FS_UNMARK_ERROR).
6747
6748Added a new function ext2fs_set_dir_block which sets the block of a
6749dblist entry, given the directory inode and blockcnt.
6750
6751Added a new function ext2fs_get_library_version() which returns the
6752current library version, and ext2fs_parse_version_string() which
6753returns a version number based on a e2fsprogs version string.
6754
6755The icount functions will return EINVAL if the passed in inode number
6756is out of bounds.
6757
6758E2fsprogs 1.07 (March 9, 1997)
6759==============================
6760
6761E2fsck is now uses much less memory when checking really large
6762filesystems (or rather, filesystems with a large number of inodes).
6763Previously a filesystem with 1 million inodes required 4 megabytes of
6764memory to store inode count statistics; that storage requirement has
6765now been reduced to roughly half a megabyte.
6766
6767E2fsck can now properly deal with bad blocks appearing inside the
6768inode table.  Instead of trying to relocate the inode table (which
6769often failed because there wasn't enough space), the inodes in the bad
6770block are marked as in use.
6771
6772E2fsck will automatically try to use the backup superblocks if the
6773primary superblocks have a bad magic number or have missing meta-data
6774blocks (or meta-data blocks which are out of range).
6775
6776E2fsck's pass 3 has been made more efficient; most noticeable on
6777filesystems with a very large number of directories.
6778
6779Completely revamped e2fsck's system of printing problem reports.  It
6780is now table driven, to make them more easily customizeable and
6781extendable.  Error messages which can be printed out during preen mode
6782are now one line long.
6783
6784Fixed e2fsck's filesystem swapping code so that it won't try to swap
6785fast symbolic links or deleted files.
6786
6787Fixed e2fsck core dumping when fixing a filesystem which has no
6788directories (not even a root directory).
6789
6790Added a check to e2fsck to make sure that the length of every
6791directory entry is a multiple of 4 (since the kernel complains if it
6792isn't).
6793
6794Added a check to e2fsck to make sure that a directory entry isn't a
6795link to the root directory, since that isn't allowed.
6796
6797Added a check to e2fsk to now make sure the '.' and '..' directory
6798entries are null terminated, since the 2.0 kernel requires it.
6799
6800Added check to write_bitmaps() to make sure the superblock doesn't get
6801trashed if the inode or block bitmap is marked as being block zero.
6802
6803Added checking of the new feature set fields in the superblock, to
6804avoid dealing with new filesystem features that this package wasn't
6805set up to handle.
6806
6807Fixed a fencepost error in ext2fs_new_block() which would occasionally
6808try to allocate a block beyond the end of a filesystem.
6809
6810When the UUID library picks a random IEEE 802 address (because it
6811can't find one from a network card), it sets the multicast bit, to
6812avoid conflicting with a legitimate IEEE 802 address.
6813
6814Mke2fs now sets the root directory's owner to be the real uid of the
6815user running mke2fs.  If the real uid is non-zero, it also sets
6816the group ownership of the root directory to be the real group-id of
6817the user running mke2fs.
6818
6819Mke2fs now has more intelligent error checking when it is given a
6820non-existent device.
6821
6822When badblocks is given the -vv option, it now updates the block that
6823it is currently testing on every block.
6824
6825Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6826currently correctly if PATH wasn't already set.
6827
6828Shared libraries now built with dependencies.  This allows the shared
6829library files to be used with dlopen(); it also makes the transition
6830to libc 6 easier, since ld.so can tell which libc a particular shared
6831library expects to use.
6832
6833Programmer's notes:
6834-------------------
6835
6836Added new abstraction (defined in dblist.c) for maintaining a list of
6837blocks which belongs to directories.  This is used in e2fsck and other
6838programs which need to iterate over all directories.
6839
6840Added new functions which test to see if a contiguous range of blocks
6841(or inodes) are available.  (ext2fs_*_bitmap_range).
6842
6843Added new function (ext2_inode_has_valid_blocks) which returns true if
6844an inode has valid blocks.  (moved from e2fsck code).
6845
6846Added new function (ext2fs_allocate_tables) which allocates the
6847meta-data blocks as part of initializing a filesystem.  (moved from
6848mke2fs code).
6849
6850Added a new I/O manager for testing purposes.  It will either allow a
6851program to intercept I/O requests, or print debugging messages to
6852trace the activity of a program using the I/O manager.
6853
6854The badblocks_list functions now store the bad blocks in a sorted
6855order, and use a binary search to speed up badblocks_list_test.
6856
6857The inode scan function ext2fs_get_next_inode() may now return a soft
6858error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6859those cases where part of an inode table is missing or there is a bad
6860block in the inode table.  
6861
6862Added a new function (ext2fs_block_iterate2) which adds new arguments to
6863the callback function to return a pointer (block and offset) to the
6864reference of the block.
6865
6866Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6867application to jump to a particular block group while doing an inode
6868scan.
6869
6870The badblocks list functions were renamed from badblocks_* to
6871ext2fs_badblocks_*.  Backwards compatibility functions are available
6872for now, but programs should be modified to use the new interface.
6873
6874Some of the library functions were reorganized into separate files to
6875reduce the size of some programs which statically link against the
6876ext2 library.
6877
6878Put in some miscellaneous fixes for the Alpha platform.
6879
6880
6881E2fsprogs 1.06 (October 7, 1996)
6882================================
6883
6884Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6885smash the backup copies in ext2fs_close().  (The problem was that when
6886e2fsck -p discovered the problem, while it was closing the filesystem
6887and exiting, it was also blowing away the backup superblocks on the
6888disk, which was less than friendly.)  We now make it the case that we
6889only write out the backup superblock and the back block descriptors if
6890the filesystem is completely free from problems.
6891
6892Fixed a bug in block_interate in the lib/ext2fs library which caused
6893e2fsck to fail on GNU Hurd-created filesystems.
6894
6895Add support for Linux/FT's bootloader, which actually uses
6896EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6897to clear the inode.
6898
6899Add support for the "A" (no atime update) attribute.  (Note: this
6900attribute is not yet in production kernels.)
6901
6902The test suite is not automatically run when doing a "make all" from
6903the top level directory.  Users should manually run "make check" if
6904they wish to run the test suite.
6905
6906Upon a preenhalt(), make the printed message more explicit that
6907running e2fsck "MANAULLY" means without the -p or -a options.
6908
6909In e2fsck, if a disconnected inode is zero-length, offer to clear it
6910instead of offering to connect it to lost+found.
6911
6912In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6913e2fsck to be run over it, change e2fsck to explicitly display this
6914fact.
6915
6916For dumpe2fs and e2fsck, cause the -V option to print out which
6917version of the ext2fs library is actually getting used.  (This will
6918help detect mismatches of using a 1.06 utility with a 1.05 library,
6919etc.)
6920
6921Programmers' notes:
6922-------------------
6923
6924EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6925the naming convention.
6926
6927In ext2fs_initialize(), make sure the description for the inode bitmap
6928is correctly initialize.
6929
6930Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6931
6932E2fsprogs 1.05 (September 7, 1996)
6933==================================
6934
6935Add support for new fields in the ext2 superblock --- volume name,
6936volume UUID, and last mounted field.  Dumpe2fs displays these fields,
6937tune2fs and mke2fs allows you to set them.  E2fsck will automatically
6938generate a UUID for those volumes that don't have them.  
6939
6940Put in support for e2fsck to recognize HURD specific ext2 features ---
6941most notably, the translator block.  The e2fsprogs tools will now use
6942the creator_os field in the superblock to correctly handle different
6943OS-specific variants of the ext2 filesystem.
6944
6945E2fsck now fixes inodes which have a the deletion time set, but which
6946have a non-zero i_link_count field by offering to clear the deletion
6947time.  Previously e2fsck assumed that the inode was deleted (per 0.3c
6948ext2 kernel behavior) and offered to unlink the file.
6949
6950If e2fsck sets the clean bit, but nothing else, set the exit code
6951FSCK_NONDESTRUCT.  After all, e2fsck did fix a filesystem error --- it
6952set the filesystem valid bit when it was previously cleared.  :-) This
6953was needed to make the HURD fsck driver happy.
6954
6955If the  user  refuses to attach an  unattached  inode, e2fsck  will no
6956longer set the inode's link count.  Otherwise, the  inode would end up
6957getting marked as unused, which might cause loss of data later.
6958
6959Make the message issued by e2fsck when the superblock is corrupt less
6960confusing for users.  It now mentions that another reason for the
6961"corrupt superblock" message might be that the partition might not be
6962an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6963
6964Make the libext2 library more robuest so that e2fsck won't coredump on
6965an illegal superblock where the blocksize is zero.  (f_crashdisk is
6966the test case).
6967
6968By default, create filesystems where the default checkinterval is 6
6969months (180 days).  Linux servers can be robust enough that 20 reboots
6970can be a long, long time.
6971
6972Added configure flag --enable-old-bitops, which forces the bitops to
6973use the old (native) bitmask operations.  By default on the sparc
6974platform, the standard ext2 bit ordering is now used.
6975
6976Added a new feature to e2fsck to byte-swap filesystems; this can be
6977used to convert old m68k filesystems to use the standard byte-order
6978storage for the superblock, inodes, and directory blocks.  This
6979function is invoked by using the '-s' option to e2fsck.
6980
6981Debugfs's "dump" command has been enhanced so that it writes out the
6982exact size of the file so that the nulls at the end of the file are
6983eliminated.  The command also accept a new "-p" option which will
6984attempt preserve to preserve the ownernship, permissions, and
6985file modification/access times.
6986
6987Debugfs has two new options, -f and -R.  The -R option allows the user
6988to execute a single debugfs command from the command line.  The -f
6989option allows the user to specify a "command file" containing debugfs
6990commands which will get executed.
6991
6992Dumpe2fs now pretty prints the check interval, instead of just
6993printing the check interval as a number of seconds.
6994
6995Fix bugs in debugfs: the params command when no filesystem is opened
6996no longer causes a core dump.  It is now possible to unlink a file
6997when a pathame containing a '/' is specified.
6998
6999Tune2fs has a new -C option which sets the number of times the
7000filesystem has been mounted.
7001
7002Fix the chattr '-v' option so that it actually works.  Chattr was
7003being buggy about the -v option parsing.
7004
7005Programmers' notes:
7006-------------------
7007
7008The directory lib/uuid contains a set of library routines to generate
7009DCE compatible UUIDs.  
7010
7011Extended ext2fs_namei() to handle symbolic links.  Added new function
7012ext2fs_nami_follow() which will follow last symbolic link in the case
7013where the pathname points to a sym link.
7014
7015The ext2fs_block_iterate function will now return the HURD translator
7016block, if present.  The new flag BLOCK_FLAG_DATA_ONLY will cause the
7017iterator to return data blocks only.  The ext2fs.h file now defines
7018constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
7019BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
7020count field of the iterator callback function.
7021
7022The test script driver now takes an optional second argument, which is
7023the test case to be run.  This allows you to run a test case without
7024needing to run the entire test suite.
7025
7026On Linux ELF systems, install the .so files in the correct places
7027(/usr/lib).  The .so files must be stored in the same directory as the
7028.a files.
7029
7030Fixed miscellaneous HURD compilation issues with header file being
7031included in the right order.
7032
7033Fixed debugfs so that it resets optind to zero, not one, since setting
7034optind to zero is more correct.
7035
7036
7037E2fsprogs 1.04 (May 16, 1996)
7038=============================
7039
7040First "official" (1.03 was a limited release only) to support building
7041e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
7042kernels).
7043
7044This package includes a RPM specs file, that it can be built using the
7045RedHat Package Manager.
7046
7047E2fsck now prints a hint that if there are lots of incorrectly located
7048inode bitmaps, block bitmaps, and inode table blocks, the user might
7049want to try using e2fsck -b 8193 first, to see if that fares any
7050better.
7051
7052For ext2 filesystem written with the hurd, debugfs will now print out
7053the translator field when printing an inode structure.
7054
7055Lots of miscellaneous linking/installation cleanups:
7056
7057  Libraries are now linked using a relative pathname, instead of
7058  relying on -L working correct.  It doesn't, in many cases, including
7059  current versions of GNU ld.  This guarantees that the build tree is
7060  linking with the right libraries, instead of the ones installed in
7061  /usr/lib.
7062
7063  Header files, man pages, and the et/ss shell scripts are now
7064  generated using a custom substitution script, instead of relying on
7065  the configure script.  This prevents needless recompilation of
7066  files; in addition, the custom substitution script is much faster.
7067
7068  e2fsck may now be linked dynamically, by using the
7069  --enable-dynamic-e2fsck flag to configure.  This is not recommended,
7070  since it increases e2fsck's dependence on other files, but some
7071  people need to save disk space, and other critical programs on their
7072  systems were being linked dynamically anyway.
7073
7074  Programs such as fsck which didn't need to be linked against
7075  libext2fs (or mke2fs which didn't need to be linked against libe2p)
7076  only link against libraries they actually need.  Otherwise, those
7077  programs would require the presense of libraries that otherwise
7078  could be removed from a rescuse diskette.
7079
7080  The ss include files are now installed correctly so they can
7081  actually be used by another package.
7082
7083  If the profiling libraries are built, they are now installed on a
7084  "make install-libs".
7085
7086
7087E2fsprogs 1.03 (March 27, 1996)
7088===============================
7089
7090Change the m68k bit numbering for bitmasks to match the bit numbering
7091used by all other ext2 implementations.  (This change was requested by
7092the m68k kernel development team.)
7093
7094Support (in-development) filesystem format revision which supports
7095(among other things) dynamically sized inodes.
7096
7097Fixed a bug in the ext2 library so that an intelligent error is
7098returned if mke2fs is run with a ridiculously small number of blocks
7099for a partition.
7100
7101Fixed a bug in the ext2 library which required that the device be
7102openable in read/write mode in order to determine its size.  This
7103caused e2fsck -n to require read/write access when it was not
7104previously necessary.
7105
7106Fixed a bug in e2fsck which casued it to occasionally fail the test
7107suite depending on which version of the floating point library it was
7108using.
7109
7110Fixed a bug in e2fsck so that it now halts with a fatal error when
7111certain superblock consistency checks fail.  Previously it continued
7112running e2fsck, with some potential confusing/damaging consequences.
7113
7114Added new flag to fsck which allows the root to be checked in parallel
7115with other filesytems.  This is not the safest thing in the world to
7116do, but some system administrators really wanted it.
7117
7118Fixed -Wall flames in lib/ss.
7119
7120
7121E2fsprogs 1.02 (January 16, 1996)
7122=================================
7123
7124Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
7125
7126Change e2fsck to print statistics of how many non-contiguous files are
7127on the system.  Note that a file which is larger than 8k blocks, it is
7128guaranteed to be non-contiguous.
7129
7130In mke2fs, print a warning message if a user tries to format a whole
7131disk (/dev/hda versus /dev/hda1).  If a user really wants to format a
7132whole disk, the -F (force) option forces mke2fs to format a whole disk
7133as a filesytem.
7134
7135Fix a bug in fsck where in some cases it might start checking
7136partitions in the next pass before it finishes checking partitions in
7137the current pass.  This still won't cause two partitions on the same
7138disk will be checked, so it's rarely a problem in real life.
7139
7140Patch lsattr so that it won't hang when checking a named pipe.
7141
7142Minor compilation fixes:
7143	* Fix the order of libraries that were linked in debugfs.
7144	* Allow the sources to be compiled with -ansi turned on.
7145
