RELEASE-NOTES revision d6a3e41172ce43b4a92fae0791beb7592a4575b1
1E2fsprogs 1.42.4 (June 12, 2012)
2================================
3
4Fixed more 64-bit block number bugs (which could end up corrupting
5file systems!) in e2fsck, debugfs, and libext2fs.
6
7Fixed e2fsck's handling of the journal's s_errno field.  E2fsck was
8not properly propagating the journal's s_errno field to the superblock
9field; it was not checking this field if the journal had already been
10replayed, and if the journal *was* being replayed, the "error bit"
11wasn't getting flushed out to disk.
12
13Fixed a false positive complaint by e2fsck if all of the extents in
14the last extent tree block are uninitalized and located after the end
15of the file as defined by i_size.
16
17The dumpe2fs will now display the journal's s_errno field if it is
18non-zero, and it will also display the journal's 64-bit feature flag
19if present.
20
21Fix e2fsck so that it always opens the device file in exclusive mode
22when it might need to modify the file system, and never if the -n
23option is specified.  (Previously, there were a few corner cases where
24it might get things wrong in either direction.)
25
26E2fsck now correctly truncates or deallocates extent-mapped inodes on
27the orphan list.  The root cause was a bug in libext2fs's block
28iterator which could end up skipping an extent when the last block in
29an extent is removed, causing the current extent to be removed from
30the extent tree.
31
32E2fsck now correctly sets the global free block and inode counts when
33truncating or removing inodes on the orphan list in preen mode.
34Previously, it would leave these values would be set incorrectly,
35which is largely a cosmetic issue since the kernel no longer pays
36attention to those fields, but it can cause spurious complaints in
37subsequent e2fsck runs.
38
39Fix i_blocks accounting when the libext2fs library needs to add or
40remove an extent tree block  on bigalloc file systems.
41
42The lsattr and chattr programs now support the No_COW flag for the
43benefit of btrfs.
44
45Debugfs now interprets date strings of the form @ddd as ddd seconds
46after the beginning of the epoch.  This is handy when setting an inode
47number into the d_time field when debugging orphan list handling.
48
49Fix a precedence bug with built-in quota support which might result in
50e2fsck paying attention to the quota inode field even if the built-in
51quota feature flag is not set.  Fortunately, in practice that
52superblock field should be zero for non-built-in quota file systems,
53so it's unlikely this bug would have caused problems.
54
55Updated/fixed various man pages.  (Addresses Debian Bugs: #674453,
56#674694)

58Programmer's Notes
59------------------
60
61The regression test suite can now run the integration tests in the
62tests directory in parallel, via "make -jN check".
63
64Add new test, f_zero_extent_length which tests e2fsck's handling of
65the case where all of the extents in the last extent tree block are
66uninitialized extents after i_size.
67
68Add a new test, f_jnl_errno, which checks handling of an error
69indication set in the journal superblock.
70
71Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
72of a 64-bit journal.
73
74Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
75tests e2fsck's handling of orphan inodes in preen mode, and truncation
76of extent inodes on the orphan list.
77    
78Fixed more OS X portability issues.
79    
80
81E2fsprogs 1.42.3 (May 14, 2012)
82===============================
83
84Fix a bug in the Unix I/O manager which could cause corruption of file
85systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
86(i.e., when unsigned long is 32-bits).  Also fix a bug which caused
87dumpe2fs to incorrectly display block numbers > 32-bits.
88
89Improve the support for integrated quota files (where quota is a first
90class supported feature using hidden files in the ext4 file system).
91Previously the quota file was getting rewritten even when it was not
92necessary, and e2fsck would erroneously try to hide quota files which
93were already hidden.
94
95Quiet complaints in e2fsck when the total free blocks or inodes are
96incorrect in the superblock after an system crash, since we don't
97update nor depend on the superblock summaries at each commit boundary.
98
99Fixed a regression introduced in 1.42.2 which would cause applications
100outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
101would were still using the legacy 32-bit bitmaps) to crash.  This was
102due to missing 32-bit compat code in side the function
103ext2fs_find_first_zero_generic_bmap().  (Addresses Red Hat Bugzilla:
104#808421)
105    
106Fix a bug which would cause mke2fs to fail creating the journal if
107/etc/mtab and /proc/mounts are missing.  (Addresses Sourceforge Bug:
108#3509398)
109    
110Updated/fixed various man pages.
111
112Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
113translations
114
115Fixed various Debian Packaging issues.
116
117
118Programmer's Notes
119------------------
120
121Change the nonsensically wrong types in the function signature of the
122inline function ext2fs_find_first_zero_block_bitmap2().  This was
123caused by a cut and paste error; fortunately no code in e2fsprogs used
124this inline function, and there are any users of this functions
125outside of e2fsprogs.
126
127Add support for systems which have valloc(), but which do have
128posix_memalign() nor memalign() (such as MacOS 10.5).
129
130Refactor and clean up the allocation of aligned buffers for Direct I/O
131support.  Previously some allocations were requesting a greater
132alignment factor that what was strictly necessary.  Also optimize
133reading and writing bitmaps using Direct I/O when the size of the
134bitmap did not fully cover the file system blocksize.
135
136Reserve the codepoints for the INCOMPAT features LARGEDATA and
137INLINEDATA.
138
139Improved the regression test suite by adding some new integration
140tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
141jbd2 format, as well as f_eofblocks which tests the new handling of
142uninitialized and initialized blocks beyond i_size.  Also add a new
143unit test which verifies 32-bit bitmaps support and the new
144find_first_zero primitives.
145
146Add a few dependencies to fix parallel (make -j) builds.
147
148Removed bash'isms which were breaking the regression test suite on
149systems where /bin/sh is not bash.
150
151The config.guess and config.sub have been updated to the 2012-02-10
152version.
153    
154Fix a portability problem caused by assuming the present of mntent.h
155means that setmntent() exists.  Instead, explicitly test for this in
156the configure script.
157
158If the sys/signal.h header file does not exist, don't try to include
159it, since it's not available on all systems.
160
161Add support for systems that do not support getpwuid_r()
162    
163The configure script now supports a new option,
164--enable-relative-symlinks, which will install relative symlinks for
165the ELF shared library files.  (Addresses Sourceforge Bug: #3520767).
166    
167When building BSD shared libraries make sure the LDFLAGS variable is
168passed to the linker.  Fixing this allows, for example, e2fsprogs to
169be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
170#3517272)
171    
172Fix gcc -Wall nitpicks
173
174
175E2fsprogs 1.42.2 (March 27, 2012)
176=================================
177
178The resize2fs program uses much less CPU and is much faster for very
179large file systems.  (Addresses Debian Bug: #663237)
180
181The seti and freei commands in debugfs can now take an optional length
182argument to set and clear a contiguous range of inodes.
183
184E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
185plan to remove support for it from the kernel file system driver.  It
186really wasn't very useful and was causing more problems than it
187solves.  Since e2fsck will complain if inodes that should have
188EOFBLOCKS_FL do not have the flag set, we are going to remove this
189check from e2fsprogs first, and then only remove the flag from the
190kernel much later.
191
192The mke2fs program can now use direct I/O via "mke2fs -D".  This will
193slow down the mke2fs, but it makes it more polite on a loaded server
194by limiting the amount of memory that gets dirtied by mke2fs when it
195is using buffered I/O.
196
197E2fsck was needlessly closing and re-opening the file system as a side
198effect of adding Multiple Mount Protection (MMP).  This isn't
199necessary for non-MMP file systems, so drop it.
200
201Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
202can more easily diagnose memory allocation failures caused by
203insufficient memory.  E2fsck will now abort if there are memory
204allocation failures when the file system is initially opened and
205during the block group descriptor checks.  (Addresses Google Bug:
206#6208183)
207
208If there are incorrect block group checks, e2fsck will now report the
209incorrect and corrected checksum values.
210
211The e2fsck progam can now write log files containing the details of
212the problems that were found and fixed directly, via configuration
213parameters in /etc/e2fsck.conf.
214
215Added the ability to limit the number of messages reported by e2fsck
216for a given problem type.  This avoids a potential bottleneck if there
217is a serial console which can cause a boot sequence to take a long
218time if e2fsck needs to report many, many file system errors.
219
220The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
221them to use much less memory for large file systems.
222
223The dumpe2fs program will now print the expected block group checksum
224if it is incorrect.  This helps to diagnose problems caused by
225incorrect block group checksums.
226
227E2fsck now checks for extents with a zero length, since the kernel
228will oops if it comes accross such a corrupted data structure.  (See
229https://bugzilla.kernel.org/show_bug.cgi?id=42859)
230
231E2fsck has a number of bugs relating to discard that have been fixed.
232(1) Fixed a bug which could cause e2fsck to discard portions of the
233inode table which were actually in use.  (2) E2fsck will now avoid
234using discard if the block device doesn't zero data on discard, since
235otherwise this could cause problems if the file system gets corrupted
236in the future.  (3) E2fsck will now avoid using discard when it is run
237in read-only mode.  (4) Fixed a bug which caused e2fsck to not issue
238discards in the last block group.
239
240E2fsck's CPU utilization in pass 5 has been optimized, which will
241speed up e2fsck slightly.
242
243E2image will now skip copying uninitialized bitmap and inode table
244blocks.
245
246Fixed mke2fs -S so it does not corrupt the first block group's
247information.
248
249E2fsck will now check the new sysfs interface to determine if we are
250using the battery or AC mains.  (Addresses SourceForge Bug: #3439277)
251
252Updated/fixed various man pages.  (Addresses Debian Bug: #665427)
253
254Fixed various Debian Packaging issues.  (Addresses Debian Bug: #665885)
255
256Programmer's Notes
257------------------
258
259Fixed various portability issues for non-Linux systems, particularly
260MacOS X, as well as Linux systems running with the just-released glibc
2612.15.
262
263Fix file descriptor leak in ext2fs_close() if the file system with
264uninit_bg is opened read/only with a backup superblock.  (Addresses
265SourceForge Bug: #3444351)
266
267Fixed an invalid return in a non-void function in the quota code.
268(Addresses SourceForge Bug: #3468423)
269
270Fixed the debian rules file so that the calls to dpkg-buildflags works
271when the shell is dash.
272
273The debian package build now uses V=1 so that there is more
274information about potential build failures in debian buildd logs.
275
276If the uninit flags get cleared by functions such as
277ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
278superblock is marked dirty and the block group descriptor checksum is
279updated if necessary.
280
281The debian rules file will now try to load debian/rules.custom of it
282exists.  This flie can skip various builds for speed reasons if there
283is no need for the e2fsck-static or udeb packages.  Available
284customizations in the rules file includes SKIP_STATIC=yes,
285SKIP_BF=yes, and SKIP_DIETLIBC=yes.
286
287In addition, if the file misc/mke2fs.conf.custom.in exists in the
288source tree, it will be used instead of the standard misc.conf file in
289the upstream sources.  This makes it easier for Debian-derived systems
290to distribute a custom mke2fs.conf file without having to worry about
291merge issues if future versions of e2fsprogs makes changes in the
292upstream default version of mke2fs.conf.
293
294
295E2fsprogs 1.42.1 (February 17, 2012)
296===================================
297
298The mke2fs and e2fsck now use significantly less memory when creating
299or checking very large file systems.  This was enabled by adding
300extent-based bitmaps which are stored using a red-block tree, since
301block and inode allocations tend to be contiguous.
302
303The command mke2fs -S is used as a last ditch recovery command to
304write new superblock and block group descriptors, but _not_ to destroy
305the inode table in hopes of recovering from a badly corrupted file
306system.  So if the uninit_bg feature is enabled, mke2fs -S will now
307set the unused inodes count field to zero.  Otherwise, e2fsck -fy
308after using mke2fs -S would leave the file system completely empty.
309
310Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
311honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
312installed an mke2fs binary using that name.
313
314The usage and help messages for the -G, -t and -T options in mke2fs
315have been fixed.
316
317If e2fsck needs to use the backup group descriptors, the
318ext2fs_open2() function clears the UNINIT bits to ensure all of the
319inodes in the file systems get scanned.  However, the code which reset
320the UNINIT flags did not also recalculate the checksum, which produced
321many spurious (and scary) e2fsck messages.  This has been fixed by
322resetting cheksums when the UNINIT bits are cleared.
323
324Relax a check in e2fsck which required that the block bitmap to be
325initialized when the inode bitmap is in use.  This will allow us to
326eventually eliminate code from the kernel which forcibly initialized
327the block bitmap when the inode bitmap is first used, requiring an
328extra journal credit and disk write.  (Addresses Google Bug: #5944440)
329    
330Make sure rdebugfs (which may be installed setuid or setgid disk) does
331not honor environment variables if euid != uid or egid != gid.
332
333Debugfs's ncheck command has been optimized and now is much more
334robust with faced with corrupted file systems.  The ncheck command
335also now has a -c option which will verify the file type information
336in the directory entry to see if matches the inode's mode bits.  This
337is extremely useful when trying to use debugsfs to determine which
338parts of the file system metadata can be trusted.
339
340E2image will try to use ftruncate64() to set the i_size for raw
341images, instead of writing a single null byte.  This avoid allocating
342an extra block to the raw image, for those file systems and/or
343operating systems that support this.  (Linux does.)  In addition, fix
344a logic bug that caused the file to not be properly extended if the
345size of the last hole was exactly an multiple of a megabyte.
346
347Fixed a bug in resize2fs where for 1k and 2k file systems, where
348s_first_data_block is non-zero, this wasn't taken into account when
349calculate the minimum file system size for use with the -M option.
350
351Fixed the badblocks program to honor the -s flag when in read-only -t
352mode.  (Addresses Debian Bug #646629)
353
354Update Czech, Dutch, French, Polish, and Sweedish translation from the
355Translation Project.
356
357Fixed various Debian Packaging issues so that dpkg-buildflags is used
358if present, which allows e2fsprogs to be built with security hardening
359flags.  (Addresses Debian Bugs: #654457)
360
361Programmer's Notes
362------------------
363
364Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
365This was only an issue for programs compiled against e2fsprogs 1.41
366that manipulate bitmaps directly.  (Addresses Sourceforge Bugs:
367#3451486)
368
369The libext2fs library now uses sysconf() to fetch the page size, instead
370of the deprecated getpagesize().
371
372The ext2fs_get_pathname() function will return a partial path if an a
373directory in the path is not a directory, displaying it as an inode
374number in angle brackets instead of giving up and displaying an error.
375This is much more helpful when a user is trying to debug a corrupted
376file system.
377
378Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
379
380Added a new library function, ext2fs_file_get_inode_num(), for use by
381fuse2fs.
382
383Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
384file, it actually works.
385
386The block iterator now properly honors the BLOCK_ABORT flag for
387extent-based flags.  Previously, it didn't, which generally made code
388be less efficient, but it could cause bugs in ext2fs_link(), for
389example, by causing it to insert multiple directory entries.
390
391Fixed an (harmless other than causing a compiler warning) use of an
392uninitialized variable in e2fsck's MMP code.
393
394
395E2fsprogs 1.42 (November 29, 2011)
396==================================
397
398This release of e2fsprogs has support for file systems > 16TB.  Online
399resize requires kernel support which will hopefully be in Linux
400version 3.2.  Offline support is not yet available for > 16TB file
401systems, but will be coming.
402
403This release of e2fsprogs has support for clustered allocation.  This
404reduces the number of block (now cluster) bitmaps by allocating and
405deallocating space in contiguous power-of-2 collections of blocks,
406which are called clustered.  This is a file system level feature,
407called 'bigalloc', which must be enabled when the file system is
408initially formatted.  It is not backwards compatible with older
409kernels.
410
411Added support for the Multi-Mount Protection (MMP) feature.
412
413E2fsck more efficiently uses scratch files for really big file
414systems.  (This is a feature that has to be turned on explicitly; see
415[scratch_files] in the e2fsck.conf man page.)
416
417Fix a bug in e2fsck where if the free blocks and inodes counts are
418incorrect, e2fsck would fix them without printing an error message.
419This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
420any explanation of what was fixed.
421
422E2fsck will no longer attempt to clone an extended attribute block in
423pass1b handling if the file system does not support extended
424attributes.
425
426E2fsck will be more careful accidentally asking the user to continue
427if the file system is mounted, so that an escape sequence won't cause
428a false positive.  (Addresses Debian Bug: #619859)
429
430E2fsck now uses less cpu time in pass 5 when large portions of the
431bitmaps are uninitialized.
432
433E2fsck will no longer segault when a corrupted file system has a bad
434extent, and removing it leads to a block needing to be deallocated.
435(Addresses SourceForge Bug: #2971800)
436
437E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
438and print debugging information to make it easier to find potential
439problems.
440
441E2fsck will check to see if the bad block inode looks insane, and will
442skip trying to use if it certain fields which should be zero look
443non-zero.  This is to avoid a corrupted bad block inode causing e2fsck
444to get confused and do more harm than good.
445
446If e2fsck modifies certain superblock fields which the kernel doesn't
447look at, it will now mark the superblock as dirty without marking the
448file system as changed.  This avoids signalling the init scripts that
449a reboot is necessary, since the kernel isn't going to look at those
450fields, so it won't care if they have been changed.
451
452Fixed a bug in the libext2fs library (in the binary search routine of
453the icount abstraction) that could (very, very rarely) cause e2fsck to
454die in the middle of pass 1 or pass 2 processing.
455
456E2fsck will not try to do a discard operation if the -n option was
457specified on the command line.
458
459E2fsck now supports an extended "discard" option which will cause
460e2fsck to attempt discard all unused blocks after a full, successful
461file system check.
462
463E2fsck will check for the bad block inode to make sure it looks sane
464before trusting it, to avoid causing more harm than good to the file
465system.
466
467E2fsck now returns additional status bits in its exit code if it
468aborts early in the e2fsck run.
469
470E2fsck now correctly calculates the maximum file size in the case of
471the huge_file file system feature enabled without extents.
472
473The mke2fs and e2fsck programs now tries to use the punch hole command
474as a "discard" when operating on normal files.
475
476The e2image program now supports the qcow2 format, which is a more
477efficient way of capturing file system dumps.
478
479Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
480per-device defaults to be specified in the configuration file.
481
482Mke2fs now supports the reserved_ratio relation in the [defaults] and
483[fs_types] section in mke2fs.conf.
484
485Mke2fs now creates extent-mapped directories for the root and
486lost+found directories.
487
488Mke2fs will skip zero'ing the journal if the extended option
489"lazy_journal_init" is specified.  This can save a lot of time, but it
490does add a small amount of risk if the system crashes before the
491journal is overwritten entirely once.  It is epsecially useful for
492testing.
493
494Mke2fs will now create file systems that enable user namespace
495extended attributes and with time- and mount count-based file
496system checks disabled.
497
498Mke2fs will not set a stride or strip size of one block based on block
499device attributes obtained from sysfs.
500
501Mke2fs now displays a progress report during the discard process.
502
503Mke2fs now handles extreme file system parameters correctly which
504previously caused the inodes per group to drop below 8, leading to a
505segfault.  (The inodes per group must be a multiple of 8, but the code
506didn't correctly deal with an inodes per group count less than 8.)
507
508Mke2fs and tune2fs previously would give an error if the user tried
509setting the stride and stripe-width parameters to zero; but this is
510necessary to disable the stride and stripe-width settings.  So allow
511setting these superblock fields to zero.  (Addresses Google Bug:
512#4988557)
513
514Mke2fs now gives a warning if the auto-detected block size exceeds the
515system's page size.
516
517If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
518is the default), mke2fs will now set the s_max_mnt_count superblock
519field to -1, instead of 0.  Kernels older then 3.0 will print a
520spurious message on each mount then they see a s_max_mnt_count set to
5210, which will annoy users.  (Addresses Debian Bug: #632637)
522    
523The default mke2fs.conf now has entries for "big" and "huge", which
524are needed for very big file systems.
525
526The resize2fs program now has support for a new online resize ioctl
527that can support file systems > 16TB, once it arrives in v3.x kernels.
528
529Fixed bug which caused resize2fs to fail when shrinking an empty file
530system down to its minimal size.  (Addresses Sourceforge Bug #3404051)
531
532Fixed tune2fs's mount options parsing.  (Addresses Debian Bug: #641667)
533
534Allow tune2fs to remove external journals if the device can not be
535found.
536
537Debugfs's icheck will now correctly find inodes which use the
538searched-for block as an extended attribute block.
539
540Debugfs now has a new "punch" command which remove blocks from the
541middle of an inode.
542
543Debugfs now has a new "e2freefrag" command which analyzes the free
544space fragmentation of the file system, using the same code as the
545e2freefrag program.
546
547Debugfs now has a "filefrag" command which displays information about
548a file's fragmentation.
549
550Add support to build a metadata-only, read-only, stripped-down version
551of debugfs called rdebugfs.
552
553Fixed a potential stack overrun bug in debugfs.
554
555The badblocks program now correctly recovers from I/O errors when
556direct I/O is being used.  The badblocks command now also supports a
557-B option which forces the use of buffered I/O, and the -v option will
558provide a more detailed breakdown of read, write, and failed
559comparison errors.
560
561Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
562
563Added support for journals larger than 2GB.
564
565Support using both hard links and symlinks when installing e2fsprogs.
566
567Add overflow checking to tune2fs -i's fsck interval, which must fit in
568a 32-bit field.
569
570The debugfs command now has a new 'blocks' command which prints out
571data blocks of a particular inode in a format which is useful for
572scripting.
573
574Filefrag will report 0 extents correctly in verbose mode.  (Addresses
575RedHat Bugzilla: #653234)
576
577Filefrag has been fixed so its -v report prints the correct expected
578block number (previously there had been an off-by-one error).  In
579addition, it will now display the number of contiguous extents when -v
580is not specified.  This makes it consistent with the number of extents
581printed when the -v option was specified.  In addition, the number of
582contiguous extents is far more interesting/useful than the number of
583physical extents for very large files.  (Addresses Debian Bug:
584#631498, #644792)
585    
586Logsave's usage message has been fixed.  (Addresses Debian Bug:
587#619788)
588
589Avoid an infinite loop in ext2fs_find_block_device() if there are
590symlink loops in /dev caused by a buggy udev.
591
592Added a useful "fallocate" program to the contrib directory.
593
594Fixed an ABI compatibility problem in libext2fs which broke the dump
595program.  Also added back some macros which dump needed so it could
596compile against the latest version of ext2_fs.h (Addresses Debian Bug:
597#636418)
598
599Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
600Debian Bug: #641667)
601
602Added internationalization support for libcom_err error table strings.
603
604Fixed various spelling mistakes found in various output strings found
605by I18N translators.
606
607Update translations: French, Chinese, Germany, Indonesian, Swedish,
608Vietnamese, Polish, Dutch, Czech.  (Addresses Debian Bugs: #520985,
609#620659)
610
611Fixed various Debian Packaging issues.  (Addresses Debian Bugs:
612#614662, #632169, #641838, #627535, #629355)
613
614Updated/clarified man pages.  (Addresses Debian Bugs: #639411,
615#642193, #634883)
616
617Programmer's Notes
618------------------
619
620Initial support for quota as an integrated feature, where the quota
621files are hidden system files that are automatically maintained by
622e2fsck is present, although disabled by default.  It must be enabled
623by using the configure option --enable-quota.
624
625Reserved the on-disk fields for the metadata checksum and snapshot
626features, which are currently in development.
627
628The ext2fs library now has the new functions ext2fs_punch(),
629ext2fs_get_memzero() and ext2fs_file_get_inode().
630
631The ext2fs library now has support for calculating the crc32c checksum
632(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
633
634The I/O manager now supports the discard operation.
635
636Reserved file system code points for new 1st class quota feature.
637
638Shortened the compilation lines by moving the autoconf defines to
639a config.h header file.
640
641Fixed a potential free of an unitialized pointer in
642ext2fs_update_bb_inode().
643
644Fixed miscellaneous gcc -Wall and coverity warnings.
645
646Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
647
648Fixed a build failure when OMIT_COM_ERR is defined.
649
650Improved error checking and fixed memory leaks caused by error return
651paths.
652
653Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
654the fsync() to be skipped.
655
656Added a test for extent-mapped journals by mke2fs and tune2fs.
657
658Added a test for creating a large (over 4GB) journal using mke2fs.
659
660Added a test to make sure the inode size remains constant.
661
662The regression test script now prints the list of which tests failed.
663
664The regression test system now uses /tmp for its scratch files, which
665is often a tmpfs mounted file system and hence much faster.
666
667The i_e2image test was fixed so it works with valgrind.
668
669Tests that rely on debugfs are now skipped if debugfs wasn't built.
670
671Fixed the dependencies for "make check" so all required dependencies
672are built before running the gression tests.
673
674A link to com_err.h is installed in $(includedir) during a "make install".
675
676The po/*.gmo files are automatically rebuilt if they are missing or
677out of date.  This helps out Debian packaging.
678
679Allow ext2fs_get_memalign() to compile on systems that don't have
680posix_memalign().
681
682Fixed a namespace leak in libext2fs (tdb_null).
683
684
685E2fsprogs 1.41.14 (December 22, 2010)
686=====================================
687
688Fix spurious complaint in mke2fs where it would complain if the file
689system type "default" is not defined in mke2fs.conf.
690
691The resize2fs program will no longer clear the resize_inode feature
692when the number reserved group descriptor blocks reaches zero.  This
693allows for subsequent shrinks of the file system to work cleanly for
694flex_bg file systems.
695
696The resize2fs program now handles devices which are exactly 16T;
697previously it would give an error saying that the file system was too
698big.
699
700E2fsck (and the libext2fs library) will not use the extended rec_len
701encoding for file systems whose block size is less than 64k, for
702consistency with the kernel.
703
704Programming notes
705-----------------
706
707E2fsprogs 1.41.13 would not compile on big-endian systems.  This has
708been fixed.  (Addresses Sourceforge Bug: #3138115)
709
710The ext2fs_block_iterator2() function passed an incorrect ref_offset
711to its callback function in the case of sparse files.  (Addresses
712Sourceforge Bug: #3081087)
713    
714Fix some type-punning warnings generated by newer versions of gcc.
715
716
717E2fsprogs 1.41.13 (December 13, 2010)
718=====================================
719
720E2fsck now supports the extended option "-E journal_only", which
721causes it to only do a journal replay.  This is useful for scripts
722that want to first replay the journal and then check to see if it
723contains errors.
724
725E2fsck will now support UUID= and LABEL= specifiers for the -j option
726(which specifies where to find the external journal).  (Addresses
727Debian Bug #559315)
728
729E2fsck now has support for the problems/<problem code>/force_no
730configuration option in e2fsck.conf, which forces a problem to not be
731fixed.
732
733Dumpe2fs will now avoid printing large negative offsets for the bitmap
734blocks and instead print a message which is a bit more helpful for
735flex_bg file systems.
736
737Mke2fs will now check the file system type (specified with the -t
738option) to make sure it is defined in the mke2fs.conf file; if it is
739not, it will print an error and abort.  If the usage type (specified
740with the -T option) is not defined in mke2fs.conf, mke2fs will print a
741warning but will continue.  (Addresses Debian Bug #594609)
742
743Clarified error message from resize2fs clarifying that on-line
744shrinking is not supported at all.  (Addresses Debian Bug #599786)
745    
746Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
747displayed.  (Addresses Debian Bug #555456)
748
749E2fsck will open the external journal in exclusive mode, to prevent
750the journal from getting truncated while it is in use due to a user
751accidentally trying to run e2fsck on a snapshotted file system volume.
752(Addresses Debian Bug #587531)
753
754Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
755flag.
756
757The tune2fs program can now set the uninit_bg feature without
758requiring an fsck.
759
760The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
761default mount options settings which were added in 2.6.35.
762
763The e2fsck and dumpe2fs programs now support the new ext4 superblock
764fields which track where and when the first and most recent file
765system errors occurred.  These fields are displayed by dumpe2fs and
766cleared by e2fsck.  These new superblock fields were added in 2.6.36.
767
768Debugfs now uses a more concicse format for listing extents in its
769stat command.  This format also includes the interior extent tree
770blocks, which previously was missing from stat's output for
771extent-based files.
772
773Debugfs has a new option, -D, which will request Direct I/O access of
774the file system.
775
776Mke2fs will skip initializing the inode table if a device supports
777discard and the discard operation will result in zero'ed blocks.
778
779Badblocks will now correctly backspace over UTF-8 characters when
780displaying its progress bar.  (Addresses Gentoo Bug #309909; Addresses
781Debian Bugs #583782 and #587834)
782
783E2freefrag will now display the total number of free extents.
784
785Resize2fs -P no longer requires a freshly checked filesystem before
786printing the minimum resize size.
787
788Fixed a floating point precision error in a binary tree search routine
789that can lead to seg fault in e2fsck and resize2fs.
790
791Fixed a bug in e2fsck where if both the original and backup superblock
792are invalid in some way, e2fsck will fail going back to the original
793superblock because it didn't close the backup superblock first, and
794the exclusive open prevented the file system from being reopened.
795
796Fixed a big in e2freefrag which caused getopt parsing to fail on
797architectures with unsigned chars.  (Addresses Gentoo Bug: #299386)
798
799Clarified an mke2fs error message so a missed common in an -E option
800(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
801results in a more understandable explanation to the user.
802
803Mke2fs now displays the correct valid inode ratio range when
804complaining about an invalid inode ratio specified by the user.
805
806Mke2fs now understands the extended option "discard" and "nodiscard",
807and the older option -K is deprecated.  The default of whether
808discards are enabled by default can be controled by the mke2fs.conf
809file.
810
811Mke2fs's handling of logical and physical sector sizes has been
812improved to reflect the fact that there will be some SSD's with 8k and
81316k physical sectors arriving soon.  Mke2fs will no longer force block
814size to be the physical sector size, since there will be devices where
815the physical sector size is larger than the system's page size, and
816hence larger than the maximal supported block size.  In addition, if
817the minimal and optimal io size are not exported by the device, and
818the physical sector size is larger than the block size, the physical
819sector size will be used to set the Raid I/O optimization hints in the
820superblock.
821
822E2fsck will now display a better, more specific error message when the
823user enters a typo'ed device name, instead of blathering on about
824alternate superblocks.
825
826Fixed various Debian Packaging Issues
827
828Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
829#589345, #591083; Addresses Launchpad Bug: #505719)
830
831Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
832Polish, Swedish, and Vietnamese translations.
833
834
835Programmer's Notes
836------------------
837
838Fix a dependency definition for the static and profiled blkid
839libraries which could cause compile failures in some configurations.
840(Addresses Debian Bug: #604629)
841    
842Add support for Direct I/O in the Unix I/O access layer.
843
844Fixed a memory leak in the Unix I/O layer when changing block sizes.
845
846Fixed minor memory leaks in mke2fs.
847
848Added a new function to the ext2fs library, ext2fs_get_memalign().
849
850The tst_super_size test program will check to make sure the superblock
851fields are correctly aligned and will print them out so they can be
852manually checked for correctness.
853
854Fixed some makefile dependencies for test programs in lib/ext2fs.
855
856Reserved the feature flags and superblock fields needed for the Next3
857snapshot feature.
858
859Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
860EXT4_INCOMPAT_EA_INODE.
861
862
863E2fsprogs 1.41.12 (May 17, 2010)
864================================
865
866Mke2fs now gives a correct error message if the external journal
867device is not found.  (Addresses Red Hat Bug #572935)
868
869Resize2fs -P will now refuse to print a minimum size if the file
870system is not clean.  Previously it would go ahead and print a minimum
871size anyway, which might not be correct, leading to user confusion.
872
873E2fsck now tests for extents that begin at physical block 0 and
874rejects them as invalid.  (Addresses Google Bug: #2573806)
875    
876Fixed a bug in e2fsck which could cause it to crash when trying to
877remove an invalid extent and the block bitmaps hadn't yet been loaded.
878(Addresses SourceForge Bug: #2971800)
879    
880E2fsck now will completely skip time-based checks if the system clock
881looks insane or the option broken_system_clock is set in
882/etc/e2fsck.conf.
883
884E2fsck would previously report an i_blocks corruption for a 4T file
885created using posix_fallocate; this bug has been fixed.
886
887E2fsck will now correctly mark a sparse journal as invalid and will
888delete and recreate the journal to address the problem.
889
890E2fsck would previously incorrectly ask the user whether she would
891like to abort the file system check after finding a problem --- and
892then abort regardless of the user's answer.  This is annoying, and
893has been fixed.
894
895E2fsck can now continue even if it fails to recreate the resize
896inode; previously it would just abort the file system check
897altogether.
898
899E2fsck could potentially remove directory entries for inodes found in
900the unused region of the inode table; this would generally happen on
901ext4 file systems that do not use journaling.  This bug has been fixed
902by not clearing these directory entries once it has been established
903that bg_unused_inodes may not be trustworthy; once pass #2 has been
904completed, e2fsck will restart the file system check from the
905beginning, and then it will be safe to delete any directory entries
906pointing to inodes that appear to be deleted.  (Addresses Google Bug:
907#2642165)
908    
909E2fsck will not try to set the block group checksums if the user
910cancels the fsck with a control-C.  It's a bad idea to set the
911checksums if e2fsck hasn't been completed, and it often results an the
912error message, "Inode bitmap not loaded while setting block group
913checksum info".  (Addresses Launchpad Bug: #582035)
914
915The mke2fs program now queries the kernel for the physical as well as
916the logical sector size, and will not allow a blocksize below the
917logical, and will strongly encourage a blocksize at least as big as
918the physical blocksize.  This is needed for 4k sector drives that
919emulate 512 byte sector sizes.
920
921Mke2fs will now allow a flex_bg size of 1.  This is unusual, and
922rarely needed, but it is a legal value.
923
924E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
925not needed, and offer to clear it; this is a sign of a kernel bug, but
926more importantly, some released kernels may crash when this situation
927is encountered on ext4 file systems.  (Addresses Google Bug: #2604224)
928    
929E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
930i_size is correct.  (Kernels starting with 2.6.34 will set
931EOFBLOCKS_FL.)
932
933The com_err library will now only output ^M (a CR character) when the
934tty is in raw mode.
935
936Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
937and Vietnamese translations.
938
939Fixed various Debian packaging issues --- see debian/changelog for
940details.  (Addresses Debian Bugs: #571247, #563487)
941
942
943Programmer's Notes
944------------------
945
946The regression test suite now uses its own mke2fs.conf file, so that
947downstream distributions want change the mke2fs.conf file which is
948distributed in the RPM or dpkg file, without worrying about screwing
949up the regression test results.
950
951Always build namei.o so that building with configure --disable-debugfs
952works correctly.  Long-term, if we care about reduced e2fsprogs
953builds, we need a more general solution for deciding what .o files are
954needed for a particular build.  Given that install floppies are going
955(gone?) the way the dodo bird, we probably don't care, though.
956(Addresses Sourceforge Bug: #2911433)
957
958Add configure options --enable-symlink-build and
959--enable-symlink-install, which allow e2fsprogs be built using
960symlinks instad of hard links, and to be installed using symlinks
961instead of hard links, respectively.  It is useful when the file
962system where the build is taking place, or the file system where
963e2fsprogs is installed, can't handle hard links for some reason.
964(Addresses Sourceforge Bug: #1436294)
965
966Fixed compile warning in mke2fs.c.
967
968    
969E2fsprogs 1.41.11 (March 14, 2010)
970==================================
971
972E2fsck will no longer give a fatal error and abort if the physical
973device has been resized beyond 2**32 blocks.  (Addresses Launchpad
974Bug: #521648)
975
976Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
977the allocation status of the block <blk>.  (Addresses Debian Bug:
978#564084)
979    
980E2fsck now prints a much more emphatic and hopefully scary message
981when a file system is detected as mounted while doing a read/write
982check of the filesystem.  Hopefully this will dissuade users from
983thinking, "surely that message doesn't apply to *me*" :-(
984
985E2fsck -n will now always open the file system read-only.  We now
986disallow certain combination of options which previously were manual
987exceptions; this is bad because it causes users to think they are
988smarter than they really are.  So "-n -c", "-n -l", "-n -L", and "-n
989-D" are no longer supported.  (Addresses Launchpad Bug: #537483)
990    
991In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
992it detected a badly aligned partition.  Unfortunately, this broke some
993distribution installation scripts, so it now just prints the warning
994message and proceeds.  (Addresses Red Hat Bug: #569021. Addresses
995Launchpad Bug: #530071)
996    
997Mke2fs would take a long time to create very large journal files for
998ext4.  This was caused by a bug in ext2fs_block_iterate2(), which is
999now fixed.
1000
1001E2fsck now understands the EOFBLOCKS_FL flag which will be used in
10022.6.34 kernels to make e2fsck not complain about blocks deliberately
1003fallocated() beyond an inode's i_size.
1004
1005E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1006e2fsck -fD can corrupt non-indexed directories when are exists one or
1007more file names which alphabetically sort before ".".  This can happen
1008with ext2 filesystems or for small directories (take less than a lock)
1009which contain filenames that begin with a space or some other
1010punctuation mark.  (Addresses Debian Bug: #573923, Addresses Launchpad

1014Programmer's Notes
1015------------------
1016
1017Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
1018correctly.
1019
1020The libcom_err function now has support for Heimdal's com_right_r
1021function().  (Addresses Sourceforge Bug: #2963865, Addresses Debian

1025E2fsprogs 1.41.10 (February 7, 2010)
1026====================================
1027
1028Fix resize2fs bug which causes it to access invalid memory.
1029
1030Add libss support for libreadline.so.6.
1031    
1032Fix e2fsck's check for extent-mapped directory with an incorrect file
1033type.
1034
1035Add new e2fsck.conf configuration option, default/broken_system_clock
1036to support systems with broken CMOS hardware clocks.  Also, since too
1037many distributions seem to have broken virtualization scripts now,
1038e2fsck will by default accept dates which are off by up to 24 hours by
1039default.  (Addresses Debian Bugs: #559776, #557636)
1040
1041Fix a bug where mke2fs may not use the best placement of the inode
1042table when there is only room for a single block group in the last
1043flex_bg.
1044
1045E2fsck is now smarter when it needs to allocate blocks in the course
1046of fixing file system problems.  This reduces the number of spurious
1047differences found in pass #5.
1048
1049E2fsck will no longer rehash directories which fit in a single
1050directory block.
1051
1052E2fsck now correctly handles holes in extent-mapped directories (i.e.,
1053sparse directories which use extents).
1054
1055Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
1056
1057Fix a bug in filefrag where on platforms which can allow file systems
1058with 8k blocks, that it doesn't core dump when it sees a file system
1059with 8k block sizes.  (Thanks to Mikulas Patocka for pointing this
1060out.)
1061
1062E2fsck will correctly fix directories that are have an inaccurate
1063i_size as well as other problems in a single pass, instead of
1064requiring two e2fsck runs before the file system is fully fixed.
1065
1066Fix e2fsck so it will correctly find and detect duplicate directory
1067entries for non-indexed directories.  ( Addresses Sourceforge Bug:
1068#2862551)
1069    
1070Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
1071thinly-provisioned storage device.  This can be disabled using the -K
1072option.
1073
1074Enhance libext2fs so it works around bug in Linux version 2.6.19
1075and earlier where the /proc/swaps file was missing the header on
1076the first line.
1077
1078Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
1079was missing the header on the first line.
1080
1081Fix some big-endian bugs in e2fsck and libext2fs.
1082
1083Fix resize2fs so it works correctly on file systems with external
1084journals instead of failing early with the error "Illegal inode
1085number".
1086
1087Fix libss so that it does not seg fault when using a readline library
1088which does not supply a readline_shutdown() function.
1089
1090Updated dumpe2fs's usage message so it correctly gives the right
1091arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
1092(Addresses Launchpad Bug: #448099)
1093   
1094Teach libext2fs to ignore the high 32 bits of the i_blocks field
1095when huge_file file system feature is set, but the inode does not
1096have the HUGE_FILE_FL flag set.
1097
1098Fix e2fsck's handling of 64-bit i_blocks fields.
1099
1100E2fsck will now print "Illegal indirect block", "Illegal
1101double-indirect block", etc., instead of "Illegal block #-1" or
1102"Illegal block #-2", etc.  This makes it easier for users to
1103understand what has gone wrong.  (Addresses SourceForge Bug: #2871782)
1104
1105Mke2fs now will obtain get device topology information from blkid and
1106use it to populate the superblock stride and stripe sizes.  It will
1107also warn if the block device is misaligned
1108
1109Fix file descriptor leaks in fsck and debugfs.  (Addresses Novell Bug:
1110##524526)
1111
1112Fix the libext2fs library code to round up the bitmap size to a 4-byte
1113boundary, to prevent spurious seg faults caused by the x86
1114architecture.  This doesn't affect Linux systems, but was a major
1115problem on a number of *BSD systems.  (Addresses Sourceforge Bug:
1116#2328708)
1117
1118Fix resize2fs's minimum size required for a file system so it doesn't
1119fail when "resize2fs -M" is run.  (Addresses RedHat Bugzilla: #519131)
1120    
1121Dumpe2fs now prints summary information about the contents of the
1122journal.
1123    
1124Avoid printing scary error messages when e2fsck starts running
1125problems on low-memory systems, as it tends to panic and mislead the
1126user.  (Addresses Debian Bug: #509529)
1127
1128Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
1129modules files.  (Address Red Hat Bug: #518572)
1130    
1131Fix tune2fs so it can add a journal when an extent-enabled file system
1132is mounted.  (Addresses Launchpad bug: #416648)
1133
1134Update Czech, Indonesian, Polish and Vietnamese translations (from the
1135Translation Project).
1136    
1137Update/clarify man pages.  (Addresses Sourceforge Bug: #2822186)
1138
1139Fixed various Debian packaging issues --- see debian/changelog for
1140details.  (Addresses Debian Bugs: #540111)
1141
1142Programmer's Notes
1143------------------
1144
1145The configure script supports the --with-cc, --with-ccopts, and
1146--with-ldopts options.  Instead, the more standard use of CC=,
1147CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
1148Also, --with-ld, which never worked, was also removed.
1149(Addresses Sourceforge Bug: #2843248)
1150
1151The in-tree header files are only used if the in-tree uuid or blkid
1152libraries are used.  Otherwise, use the system-provided uuid or blkid
1153header files if using the system-provided libraries.
1154
1155Fix some build failures caused by --disable-* configure options.
1156
1157Work around a bug in autoconf 2.64.
1158
1159
1160E2fsprogs 1.41.9 (August 22, 2009)
1161==================================
1162
1163Fix a bug in e2fsck routines for reallocating an inode table which
1164could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1165filesystem feature with a relatively rare (and specific) filesystem
1166corruption.  This fix causes e2fsck to try to find space for a new
1167portion of the inode table in the containing flex_bg, and if that
1168fails, the new portion of the inode table will be allocated in any
1169free space available in the filesystem.
1170
1171Make e2fsck less annoying by only asking for permission to relocate a
1172block group's inode table once, instead of for every overlapping
1173block.  Similarly, only ask once to recompute the block group
1174checksums, instead of once for each corrupted block group's checksum.
1175
1176Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1177not present, and it needs to fall back to using the FIBMAP ioctl.
1178
1179Fix filefrag to correctly print the number of extents for zero-length
1180files.  (Addresses Debian Bug: #540376)
1181
1182Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1183to more easily debug the FIBMAP code.
1184
1185Fixed filefrag for non-extent based files.
1186
1187Add a new program, e2freefrag, which displays information about the
1188free space fragmentation in an ext2/3/4 filesystem.
1189
1190Fix inode resizing via tune2fs -I so that it works correctly in the
1191face of non-empty bad blocks inodes, and if the filesystem was
1192formatted using the "mke2fs -E stride=N" option for RAID arrays.
1193
1194Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1195and corrupt large directories if the directory needs to shrink by more
1196than one block.  (Addresses Debian Bug: #537510)
1197    
1198Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1199last mount times are in the future, they are corrected even if
1200buggy_init_scripts is set.  This is needed because otherwise resize2fs
1201will refuse to resize the filesystem, even after running "e2fsck -f".
1202(Addresses Launchpad bug: #373409)
1203
1204E2fsck will now print much fuller information when the last mount time
1205or last written time is in the future, since most people can't seem to
1206believe their distribution has buggy init scripts, or they have a
1207failed CMOS/RTS clock battery.
1208
1209Enhance dumpe2fs to dump the extent information via the 'stat'
1210command, and more detailed extent information via the new command
1211'dump_extents'.
1212    
1213Update French, Polish, Czech, and Sweedish translation from the
1214Translation Project.
1215
1216Fixed various Debian packaging issues --- see debian/changelog for
1217details.
1218

1220------------------
1221
1222Fixed miscellaneous gcc -Wall warnings.
1223
1224Fixed memory leak in error path in ext2fs_block_iterate2()
1225
1226Fixed non-Linux build of the intl directory by adding support for the
1227E/Q/V macros.
1228
1229The bitmap read/write functions now treat uninitialized bitmaps as
1230unallocated; this fixes a number of problems in all e2fsprogs for ext4
1231filesystems when there is a need to allocate new blocks or inodes, and
1232there aren't any free blocks or inodes in the already-used block
1233groups.
1234
1235Improve ext2fs_extent_set_bmap() to avoid creating new extents which
1236get inserted into the extent tree when they are not needed.
1237    
1238
1239E2fsprogs 1.41.8 (July 11, 2009)
1240================================
1241
1242Fix resize2fs's online resizing, fixing a regression which in
1243e2fpsrogs 1.41.7.   (Addresses Debian Bug: #535452)
1244
1245Fix potential filesystem corruptions caused by using resize2fs to
1246shrinking ext4 filesystems with extents enabled.  (Addresses Red Hat
1247Bug: #510379)
1248
1249Optimize uuid_generate() to avoid running uuidd if it is not setuid or
1250setgid and the currently running program doesn't have write access to
1251the uuidd work directory.
1252
1253Add safety checks (for non-Linux systems) so that uuidd isn't run with
1254file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1255will be careful not to close the file descriptor for its unix domain
1256socket when it detaches itself from the controlling tty.  Also add
1257safety checks so that if the unix domain socket between the uuid
1258library and uuidd program is closed for any reason, both the library
1259and the uuidd will return an appropriate error code instead of looping
1260in an infinite loop.
1261
1262The e2croncheck script, which creates an LVM snapshot and then checks
1263the ext3/4 filesystem via the LVM snapshot, has been added to the
1264contrib directory.
1265
1266Fix filefrag program for files that have more than 144 extents.
1267
1268Update French, Polish, Czech, Indonsian, and Sweedish translation from
1269the Translation Project.
1270
1271Fixed various Debian packaging issues --- see debian/changelog for
1272details.  (Addresses Debian Bug #535530)
1273
1274Update/clarify man pages.

1277------------------
1278
1279Fix compilation problem when configured with --disable-uuid.
1280
1281Don't build uuidgen if configured with --disable-uuid.
1282
1283Add the new library function ext2fs_test_inode_bitmap_range(), and
1284optimized ext2fs_test_block_bitmap_range(), which will be needed for
1285future optimizations for e2fsck.
1286
1287Fix makefile dependencies for libcom_err so that the Makefiles work
1288well on non-GNU make program.  (Addresses Sourceforge Patches: #2813809)
1289
1290Enhance the build system so that the full set of commands executed by
1291the Makefiles are displayed, instead of the Linux kernel summary
1292output, if the build was configured with --enable-verbose-makecmds, or
1293if GNU make is in use and the V variable is non-null, i.e., via "make
1294V=1".
1295
1296
1297E2fsprogs 1.41.7 (June 29, 2009)
1298================================
1299
1300Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
1301uninitalized data into the portion of the inode beyond the first 128
1302bytes when operating on inodes mapped via extents; potentially
1303corrupting filesystems.
1304
1305Fix memory leaks in e2fsprogs, including a very large memory leak
1306which can cause e2fsck to run out of memory when checking very large
1307filesystems using extents.
1308
1309The logsave program will now filter out the ^A and ^B characters when
1310writing to the console.
1311
1312Harden ext2fs_validate_entry() so that lsdel will not read beyond the
1313end of the block even if the directory block is corrupted.
1314
1315Fix debugfs from core dumping if the logdump command fails to open the
1316output file.
1317
1318Enhance badblocks to print the currently tested block number when
1319interrupted with ^C.
1320
1321Fix lsattr to exit with a non-zero status when it encounters errors.
1322(Addresses RedHat Bugzilla #489841)
1323
1324Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
1325filesystems as the kernel when encoding rec_len >= 64k.  For 64k
1326filesystems (currently all that is supported by e2fsprogs, this is
1327only a minor corner case).
1328
1329Resize2fs will now update the journal backup fileds in the sup0erblock
1330if the journal is moved; this avoids an unnecessary full fsck after
1331resizing the filesystem.  (Addresses RedHat Bugzilla: #505339)
1332    
1333Fix libext2fs to properly initialize i_extra_size when creating the
1334journal and resize inodes.
1335
1336Change badblocks to allow block sizes larger than 4k.
1337
1338Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
1339
1340Update Chinese and Czech translation from the Translation Project.
1341
1342Clean up various man pages.  (Addresses Debian Bug #531385 and #523063)
1343
1344
1345Programmer's Notes
1346------------------
1347
1348Add --disable-libuuid option to configure which uses an in-system
1349installed version of libuuid; the private version is enabled by
1350default.
1351
1352Add --valgrind-leakcheck option to the test_script program which runs
1353valgrind with the appropriate options to find memory leaks.
1354
1355
1356E2fsprogs 1.41.6 (May 30, 2009)
1357===============================
1358
1359Fix a critical regression in e2fsck introduced version 1.41.5 which
1360can undo updates to the block group descriptors after a journal replay.
1361
1362If e2fsck receives an I/O error while replaying the journal, prompt
1363the user whether they want to ignore the error or not; if e2fsck is
1364run in preen mode, force fsck to abort the preen pass.
1365
1366Fix a bug which would cause e2fsck to core dump if the filesystem
1367contains a corrupt extent header, and the user declines to clear the
1368inode.  (Addresses Sourceforge Bug: #2791794)
1369    
1370Fix e2fsck to restart only once in the case of multiple block groups
1371which inodes in use that are in the uninitialized part of the block
1372group's inode table.
1373
1374To reduce user confusion, if the /etc/mtab file is missing
1375ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1376new, explicit error code to indicate this case.  This will cause
1377e2fsck to give a clearer error message when the user is using buggy
1378rescue CD's that don't properly set up /etc/mtab.  (Addresses Debian
1379Bug: #527859)
1380    
1381Fix e2fsck so that if the primary group descriptors are corrupted, but
1382the backup superblock is entirely invalid, to go back to using (and
1383fixing) the priary group descriptors instead of completely giving up
1384on the filesystem.  (Addresses Debian Bug: #516820)
1385    
1386Change e2fsck to not abort a preen pass if an inode is found to have
1387i_file_acl_hi non-zero.  Ext3 filesystems don't care, and newer
1388kernels (post 2.6.29) will ignore this field.  So let's fix it
1389automatically during the preen pass instead of forcing the user to fix
1390this up manually.  (Addresses Debian Bug: #526524)
1391    
1392Add resource tracking for e2fsck passes 1b through 1d.
1393
1394Speed up e2fsck by eliminating unnecessary journal checks if the
1395filesystem is already mounted and doesn't need recovery (since the
1396kernel would have run the journal when the filesystem was mounted.)
1397Also speed up e2fsck by avoiding unnecessary block group descriptor
1398updates in ext2fs_close().
1399
1400Add support to chattr to migrate inodes from using direct/indirect
1401blocks to extents.
1402
1403Avoid corrupting the filesystem if there is an attempt to shrink a
1404filesystem using resize2fs smaller than posible by making
1405ext2fs_set_bmap() more careful not to delete the old block until the
1406new block can be inserted.  In addition, fix a bug in how the minimum
1407size of the filesystem (plus a safety margin) is calculated, and
1408modify resize2fs to refuse to shrink the filesystem below that minimum
1409size without the force flag.
1410
1411Teach blkid to try to figure out DM device names using take advantage
1412of information in sysfs when running on kernels (2.6.29 and later)
1413which provide this information in /sys/block/dm-<N>/dm/name; this is
1414much faster than scanning for the devncie number in /dev/mapper.
1415
1416Fix blkid to prefer /dev/mapper/<name> device names instad of the
1417private /dev/dm-X names.
1418
1419Add an -a option to debugfs's close_filesys command which writes any
1420changes to the superblock or block group descriptors to all of the
1421backup superblock locations.
1422    
1423Add support to the filefrag program to use the FIEMAP ioctl.
1424
1425Update Chinese translation from the Translation Project.
1426
1427Clean up various man pages.  (Addresses Red Hat Bugzilla: #502971 and
1428Launchpad Bug: #381854)
1429
1430Fixed various Debian packaging issues --- see debian/changelog for
1431details.  (Addresses Debian Bug #506064)
1432
1433
1434Programmer's Notes
1435------------------
1436
1437Add test code to make sure e2fsck's problem.c doesn't have two problem
1438codes assigned to duplicate values.
1439
1440Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1441(Addresses Sourceforge Bug: #2780205)
1442
1443Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1444function declaration for init_resource_track() and
1445print_resource_track() when RESOURCE_TRACK is not defined.
1446
1447The test code which is used to build the tst_csum progam has been
1448moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1449avoid compile problems caused by not having a prototype for
1450ext2fs_group_desc_csum().  (Addresses Sourceforge Bug #2484331)
1451
1452Update the config.guess and config.sub file to the latest from the
1453FSF, to allow e2fsprogs to build on the avr32 platform.  (Addresses
1454Debian Bug: #528330)
1455
1456Add a new function, ext2fs_extent_open2(), which behaves like
1457pext2fs_extent_open(), but uses the user-supplied inode structure
1458when opening an extent instead of reading the inode from disk.
1459
1460
1461E2fsprogs 1.41.5 (April 23, 2009)
1462=================================
1463
1464Fix a number of filesystem corruption bugs in resize2fs when growing
1465or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1466is not mounted).
1467
1468Debugfs can now set i_file_acl_high via the set_inodes_field command,
1469and print a 64-bit file acl.  This is useful for debugging filesystem
1470corruptions where the high bits of i_file_acl_high are set.  E2fsck
1471will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1472since some Linux kernel versions pay attention to this field even when
1473they shouldn't.
1474
1475Speed up e2fsck when checking clean filesystems by avoiding
1476unnecessary block reads, and coalescing the block group descriptor
1477blocks so they are read using a single read operation.
1478
1479The libuuid library will now close all file descriptors before running
1480uuidd.  This avoids problems when the calling program has open sockets
1481which then never get closed because uuidd is a long-running helper
1482daeomn.  (Addresses Launchpad bug: #305057)
1483
1484In order to avoid unnecessary full filesystem checks by e2fsck after
1485an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1486the backup superblocks.  (Addresses Red Hat Bugzilla: #471925)
1487
1488Mke2fs will avoid trying to create the journal when run in
1489superblock-only mode (mke2fs -S), since the left-over journal in the
1490inode table will cause mke2fs to fail.
1491
1492Fix a bug in libext2fs functions that check to see if a particular
1493device or filesystem image is mounted, which would cause these
1494functions to report that a file identical to the (relative) pathname
1495used by a pseudo-filesystem was mounted when in fact it was not.
1496
1497Update Czech translation from the Translation Project.
1498
1499Add Chinese (simplified) translation from the Translation Project.
1500
1501Fix support for external journals (which was broken in e2fsprogs
15021.41.4).
1503
1504Fix a regression in debugfs where the "stat" command when no
1505filesystem was open would cause debugfs to crash with a segmentation
1506violation.
1507
1508Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1509used to support filesystems without a journal.  Update the blkid
1510library so it understands this.
1511
1512The blkid library will remove an entry from the blkid cache
1513representing the entire disk if partitions are found, since presuambly
1514the device previously had no partition table, but has now transitioned
1515to using a partition table.
1516
1517Add a check to mke2fs and tune2fs that the argument to the -m option
1518(which specifies the reserved ratio) must be greater than zero.
1519(Addresses Debian Bug: #517015)
1520
1521Add support for tracking the number kilobytes written to the
1522filesystem via the superblock field s_kbytes_written.  It will be
1523updated by the kernel as well as by e2fsprogs programs which write to
1524the filesystem.  This is useful for tracking the wear to filesystems
1525on Solid Sstate Drives.
1526
1527Fix compatibility issue in the libext2fs info file and makeinfo
1528version 4.12.  (Addresses Red Hat Bugzilla: #481620)
1529
1530Update/clarify man pages.  (Addresses Debian Bug: #515693, #365619)
1531
1532Fixed various Debian packaging issues --- see debian/changelog for
1533details. (Addresses Debian Bug: #506279)
1534
1535Programmer's Notes
1536------------------
1537
1538Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
1539Bug: #521602)
1540
1541Fix various gcc compilation warnings and other programming cleanups.
1542(Addresses Red Hat Bugzilla: #486997)
1543
1544Add support for building the blkid command statically.
1545
1546Add support for disabling the built-in blkid library in favor of a
1547system-installed blkid implementation via the configure option
1548--disable-libblkid.
1549
1550
1551E2fsprogs 1.41.4 (January 27, 2009)
1552===================================
1553
1554Fixed a bug which could sometimes cause blkid to return an exit value
1555of zero for a non-existent device (Addresses Debian Bug: #502541)
1556
1557Blkid will now recognize ext3 filesystems that have the test_fs flag
1558set as ext3 filesystems.
1559
1560The blkid library will now recognize btrfs filesystems and swap
1561devices currently used by user-level software suspend.
1562
1563Tune2fs now updates the block group checksums when changing the UUID
1564to avoid causing e2fsck to complain vociferously at the next reboot.
1565
1566Tune2fs's inode size resizing algorithms have been fixed so it is not
1567vastly inefficient for moderate-to-large filesystems, due to some
1568O(n**2) and O(n*m) algorithms that didn't scale well at all.
1569
1570Fix tune2fs's inode resizing algorithm so it will not corrupt
1571filesystems laid out for RAID filesystems; in addition, tune2fs will
1572refuse to change the inode size for filesystems that have the flex_bg
1573feature enabled.  (This is a limitation in the current implementation
1574of tune2fs -I.)
1575
1576E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1577filesystems with 32-bit block numbers, when the headers for 64-bit
1578block numbers was added.  This regression has been fixed.
1579
1580Debugfs's ncheck command has been fixed to avoid printing garbage
1581characters at the end of file names.
1582
1583Fix resize2fs for ext4 filesystems.  Some blocks that that need moving
1584when shrinking filesystems with uninit_bg feature would not be moved.
1585In addition, blocks and inode table blocks were not being correctly
1586freed when shrinking filesystems with the flex_bg feable, which caused
1587resize2fs -M to fail.  Finally, when blocks are moved, make sure the
1588uninitialized flag in extents is preserved.
1589
1590Fix bug which caused dumpe2fs to abort with an error if run on a
1591filesystem that contained an external journal.
1592
1593Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1594for this in argv[0] to provide better legacy support for these
1595distributions.  This is a practice that should NOT be continued,
1596however.
1597
1598Mke2fs now has a new option -U, which allows the user to specify the
1599UUID that should be used for the new filesystem.
1600
1601Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1602minus one block.  This allows users who have read that ext3 supports
1603up to 16TB filesystems and who create a 16TB LVM to not get confused,
1604since the true limit is really 16TB minus one block.
1605
1606E2fsck will no longer abort an fsck run if block group has an errant
1607INODE_UNINIT flag.
1608
1609E2fsck now distinguishes between fragmented directories and fragmented
1610files in verbose mode statistics and in the fragcheck report.
1611
1612Fix a bug in e2fsck which casued it double count non-contiguous
1613extent-based inodes.
1614
1615E2fsck will leave some slack space when repacking directories to allow
1616room for a few directory entries to be added without causing leaf
1617nodes to be split right away.
1618
1619Fix a bug which caused e2fsck to crash when it comes across a
1620corrupted interior node in an extent tree with the error message:
1621"Error1: Corrupt extent header on inode XXXXXX"
1622
1623E2fsck problem descriptions involving the journal are no longer
1624referred to as "ext3" problems, since ext4 filesystems also have
1625journals.
1626
1627Fix a long-standing bug in e2fsck which would cause it to crash when
1628replying journals for filesystems with block sizes greater than 8k.
1629
1630Update Catalan translation from the Translation Project.
1631
1632Fixed various Debian packaging issues --- see debian/changelog for
1633details. (Addresses Debian Bugs: #503057, #502323, #511207)
1634
1635Programmer's Notes
1636------------------
1637
1638Fix build of e2fsck.profiled, and add support for building profiled
1639binaries in the misc directory if configured with --enable-profile.
1640
1641The ext2fs_open() function now performs more sanity checks on the
1642superblock to avoid potential divide by zero errors by other parts of
1643library.
1644
1645The ext2fs_read_inode_full() function now has a safety check to avoid
1646a segmentation fault on corrupted filesystems.
1647
1648The ext2fs_new_inode() function now has a sanity check so that if the
1649s_first_inode field in the superblock is insane, it will return
1650EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1651
1652To avoid segmentation faults, ext2fs_block_alloc_stats() and
1653ext2fs_inode_alloc_stats() now validates the passed inode or block
1654number to avoid overrunning an array boundary.
1655
1656Various signed/unsigned errors for variables containing block numbers
1657have been fixed.
1658
1659Accomodations for gcc's stupidity in not realizing that constant
1660strings that do not contain a '%' character are safe to use in format
1661strings have been made so that distributions that want to compile
1662e2fsprogs with -Werror=format-security have an easier time doing so.
1663
1664Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1665
1666Added the utility make-sparse.c to the contrib directory.
1667
1668The ext2fs_block_iterate2() function now reflects errors from
1669ext2fs_extent_set_bmap() to the caller, if the callback tries to
1670change a block on an extent-based file, and ext2fs_extent_set_bmap()
1671fails for some reason (for example, there isn't enough disk space to
1672split a node and expand the extent tree.
1673
1674The ext2fs_block_iterate2() function will preserve the uninit flag in
1675extents when the callback function modifies a block in an extent-based
1676file.
1677
1678E2fsck will now flag filesystems that have an insane s_first_ino field
1679in their superblock, and attempt to use a backup superblock to repair
1680the filesystem.
1681
1682
1683E2fsprogs 1.41.3 (October 12, 2008)
1684===================================
1685
1686E2fsck has been fixed so it prints the correct inode number for
1687uinit_bg related problems.
1688
1689E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1690is available on linux.  This can be disabled via a configuration
1691option in /etc/e2fsck.conf.
1692
1693Fix a file descriptor leak in libblkid when checking to see if an ext4
1694or ext4dev module exists.
1695
1696Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1697while trying to close a filesystem can lead to infinite loops.
1698(Addresses Red Hat Bugzilla #465679)
1699    
1700Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1701will cause resize2fs to drop into an infinite loop.  (Addresses Red
1702Hat Bugzilla: #465984)
1703    
1704Add a check in the Unix I/O functions in libext2fs so that when a
1705device is opened read/write, return an error if the device is
1706read-only using the BLKROGET ioctl.
1707
1708Fix debugfs's ncheck command so that it prints all of the names of
1709hardlinks in the same directory.
1710
1711Fix a bug in libblkid so it correctly detects whether the ext4 and
1712ext4dev filesystems are available, so that the ext4dev->ext4
1713fallback code works correctly.
1714
1715Programmer's Notes
1716------------------
1717
1718Fix a parallel build problem by making sure util/subst is built before
1719trying to build the lib/et directory.  (Addresses Sourceforge Bug:
1720#2143281)
1721
1722Updated "make depend" information for crc16.o
1723    
1724
1725E2fsprogs 1.41.2 (October 2, 2008)
1726==================================
1727
1728Fix e2fsck's automatic blocksize detection.  This fixes a regression
1729from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1730specifies a block number using the -b option if the blocksize option
1731isn't also specified using -B.  Unfortunately, users very commonly
1732invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1733superblock; in fack e2fsck will often suggest this kind of command
1734line.  Oops.
1735
1736Enhance the debugfs's "ncheck" command so it will print all of the
1737pathnames for the specified inodes.  (Previously, in some cases ncheck
1738might not print a pathname for an inode at all if some of the other
1739inodes had multiple hard links.)
1740
1741Enhance debugfs's "hash" command so the hash seed can be specified via
1742a command-line option.  In addition, allow the hash algorithm to be
1743specified by name instead of just by number.
1744
1745Fix e2fsck so that we don't accidentally print the translation file's
1746header when asking the user a custom question so there is no prompt
1747defined for a particular problem record.  For example, the question
1748"Run journal anyway" will get the PO header tacked on because e2fsck
1749erroneously passed the null string to _().  (Addresses Launchpad Bug:
1750#246892)
1751
1752Enhance badblocks so that it can test a normal file which is greater
1753than 2GB.
1754
1755Enhance the badblocks command so that it displays the time and
1756percentage complete when in verbose mode.  (Addresses Debian Bug:
1757#429739)
1758
1759Fix a potential memory leak in a error handling path in debugfs's
1760ncheck function.
1761
1762Fix a potential memory corruption problem if a memory allocation fails
1763in resize2fs.
1764
1765Fix the usage message for debugfs's logdump command to be consistent
1766with its man manpage.
1767
1768Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
1769and Sweedish translation from the Translation Project.
1770
1771Add documentation for the file I/O functions to the libext2fs.texinfo
1772file.  (Addresses Debian Bug: #484877)
1773    
1774Update and clarified various man pages.  (Addresses Launchpad Bug
1775#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)

1780Programmer's Notes
1781------------------
1782
1783Fix a potential file descriptor leack in libcom_err by setting the
1784close-on-exec flag for a fd used for debugging.  (Addresses Red Hat
1785Bugzilla #464689)
1786
1787Fix a potential race in libcom_err by using sem_post/sem_init.  SuSE
1788has been carrying a patch for a long time to prevent a largely
1789theoretical race condition if a multi-threaded application adds and
1790removes error tables in multiple threads.  Unfortunately SuSE's
1791approach breaks compatibility by forcing applications to link and
1792compile with the -pthread option; using pthread mutexes has
1793historically been problematic.  We fix this by using sem_post/sem_init
1794instead.
1795
1796Fix e2fsprogs-libs build failure due to 'subs' target.  (Addresses
1797Sourceforge Bug: #2087502)
1798
1799Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
1800libraries when using ELF shared libraries.
1801
1802Fix ELF shared library when building on systems that don't already
1803have the e2fsprogs shared libraries already installed.  (Addresses
1804Sourceforge Bug: #2088537)
1805
1806Fix the pkg-config files so they work correctly when linking with
1807static libraries and fix the include directory so programs don't have
1808to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
1809instead.  (Addresses Sourceforge Bug: #2089537)
1810    
1811Make sure ext2fs_swab64() is compiled for all platforms, and not just
1812for x86.  (Addresses Debian Bug: #497515)
1813    
1814Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1815non-x86 platforms.  (They had been removed for x86 earlier.)
1816
1817Fix diet libc compilation support, which had bitrotted due to lack of
1818TLC.  Fixing this improves general portability.
1819
1820When installing the link library when using ELF shared libraries,
1821avoid using absolute pathnames if the link library and the shared
1822library are installed in the same directory.  (Addresses Sourceforge
1823Bug: #1782913)
1824
1825Fix gen-tarball so it will work even if the top-level directory has
1826been renamed to something other than "e2fsprogs".  Also make
1827gen-tarball print the size of the resulting tar.gz file.
1828
1829
1830E2fsprogs 1.41.1 (September 1, 2008)
1831====================================
1832
1833Many people are forgetting to update their mke2fs.conf file, and this
1834causes ext3, ext4, and ext4dev filesystems won't get created with the
1835proper features enabled.  We address this in two ways.  First, mke2fs
1836will issue a warning if there is not definition for an ext3, ext4, or
1837ext4dev filesystem and the user is trying to create such a filesystem
1838type.  Secondly, when installing from a source build, "make install"
1839will provide basic configuration file handling for /etc/mke2fs.conf.
1840If it exists, and does not mention ext4dev, it will be moved aside to
1841/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1842be installed.  If the existing /etc/mke2fs.conf file does mention
1843ext4dev, then "make install" will install official mke2fs.conf file as
1844/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1845they should look to see if any changes need to be merged.
1846
1847The mke2fs program will now create the journal in the middle of the
1848filesystem, since this minimizes seek times on average for fsync-heavy
1849workloads.  In addition, mke2fs will now create journals using extents
1850for filesystems that support them.  This results in a more efficient
1851encoding for the journal since it eliminates the need for using
1852indirect blocks.
1853
1854The mke2fs program will avoid allocating an extra block to the
1855journal.  (Addresses Sourceforge Bug: #1483791)
1856
1857Mke2fs will correctly enforce the prohibition against features
1858(specifically read-only features) in revision 0 filesystems.  (Thanks
1859to Benno Schulenberg for noticing this problem.)
1860
1861Mke2fs previously would occasionaly create some slightly non-optimally
1862placed inode tables; this bug has been fixed.
1863
1864The mke2fs and tune2fs programs now print the correct usage message
1865describing the maximum journal size.  (Addresses Debian Bug: #491620)
1866
1867Add support for setting the default hash algorithm used in b-tree
1868directories in tune2fs (from a command-line option) or mke2fs (via
1869mke2fs.conf).  In addition, change the default hash algorithm to
1870half_md4, since it is faster and better.
1871
1872The blkid library will now recognize MacOS hfsx filesystems, and
1873correctly extract the label and uuid for hfs, hfsx, and hfsplus
1874filesystems.  (Addresses Sourceforge Feature Requests: #2060292)
1875
1876The blkid library has improved detection of JFS and HPFS filesystems.
1877(Addresses Launchpad Bug: #255255)
1878
1879The blkid library is now much more efficiently handling devicemapper
1880devices, mainly by no longer using the devicemapper library.  This can
1881speed up access for systems with a large number of device mapper
1882devices.
1883
1884Blkid had a number of cache validation bugs in libblkid that have been
1885fixed.   (Addresses Debian Bug: #493216)
1886
1887Resize2fs will now properly close out the "updating inode references"
1888progress bar so there is a newline printed before printing the final
1889"resize is successful" message.
1890
1891Resize2fs will now correctly handle filesystems with extents and/o
1892uninitialized block groups correctly when file/directory blocks need
1893to relocated (i.e., when shrinking a filesystem or if the resize_inode
1894is not present).  To support this, the ext2fs library now supports
1895initializing inode and block bitmaps that are not yet initialized when
1896allocating them using ext2fs_new_block() and ext2fs_new_inode().  In
1897addition, e2fs_block_iterate2() can now support changing the location
1898of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1899been optimized to avoid creating unnecessary new extents when updating
1900the location of blocks in the extent tree.  This will also help out
1901e2fsck's recovery of obscurely corrupted filesystems with extents,
1902when blocks are claimed by multiple inodes.
1903
1904Add support for on-line resizing ext4 filesystem with the flex_bg
1905filesystem feature.  The method for doing so is not optimal, but to do
1906a better job will require kernel support.
1907
1908E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1909debugfs programs to not be able to read e2image files; the signed
1910vs. unsigned bug in the code which read bitmaps from the e2image has
1911been fixed.   (Addresses Debian Bug: #495830)
1912
1913Resize2fs is now correctly managing the directory in-use counts when
1914shrinking filesystems and directory inodes needed to be moved from one
1915block group to another.  This bug has been around since e2fsprogs
19161.26, and is largely harmless, but does cause a filesystem corruption
1917which will be flagged by e2fsck after the filesystem has been shrunk.
1918 
1919E2fsck will no longer issue spurious complaints about the inode size
1920caused by very large extent-based files, and by blocks reallocated
1921using fallocate() with the FALLOC_FL_KEEP_SIZE option.  (Addresses
1922Kernel Bugzilla: #11341)
1923
1924Mke2fs will now set the creation timestamp on the lost+found directory
1925and the root directory.  (More generally, all new inodes created using
1926the ext2fs library will correctly set the creation timestamp.)
1927
1928E2fsck now correctly calculates ind/dind/tind statistics in the
1929presence of extent-based files.  In addition, "e2fsck -v" will report
1930statistics of the depth of extent trees in the filesystem.  E2fsck can
1931also give an inode fragmentation report using "e2fsck -E fragcheck"
1932which can be useful when debugging the kernel block allocation
1933routines.
1934
1935Fix support for empty directory blocks in ext4 filesystems with 64k
1936blocksize filesystems.
1937
1938E2fsck will now print the depth of corrupt htree directories.
1939
1940Debugfs's htree command now correctly understands extent-based
1941directories.  It will also print out the minor hash as well as the
1942major hash.
1943
1944Debugfs has a new command which will print the supported features of
1945e2fsprogs, to enable scripts to know whether the installed version of
1946e2fsprogs can support a specific feature.
1947
1948Debugfs will now write files using extents for filesystems that
1949support them.
1950
1951The error message printed by "tune2fs -I" if the inode size was too
1952small was rather confusing, so it has been improved.  Also, we won't
1953try to create an undo log until we know that command-line-specified
1954parameters such as "tune2fs -I <inode size>" are valid.
1955
1956Given some filesystems found "in the wild" that had non-zero block
1957group checksums even though the uninit_bg/gdt_sum feature was not
1958enabled, e2fsck would issue spurious error messages.  Teach
1959ext2fs_group_desc_csum_verify() to ignore the block group checksum
1960entirely if the feature flag is not set.  (Addresses Debian Bug:
1961#490637)
1962
1963The blkid program will now print out a user-friendly listing of all of
1964the block devices in the system and what they contain when given the
1965-L option.  (Addresses Debian Bug: #490527)
1966
1967The filefrag program now has a more accurate calculation for the
1968number of ideal extents.  (Addresses Debian Bug: #458306)
1969
1970The test I/O manager is now enabled by default, but its overhead is
1971only incurred when it would be enabled via the TEST_IO_FLAGS or
1972TEST_IO_BLOCK environment variables.
1973
1974Typographical errors in various program strings and usage messages
1975have been fixed; most of these were pointed out by the e2fsprogs
1976message catalog translators.  (Thanks, translators!)
1977
1978Update and clarified various man pages, as well as some typographical
1979errors in the libext2fs texinfo file.
1980
1981Fixed various Debian packaging issues --- see debian/changelog for
1982details.
1983
1984Add Indonesian and update French, Polish, Dutch, German, Sweedish,
1985Czech, and Vietnamese Translations.  (Addresses Debian Bugs: #313697,

1987
1988Programmer's Notes
1989------------------
1990
1991Fix portability problem with the badblocks group; for systems that
1992don't have nanosleep(), try using usleep() instead.
1993
1994The "make check" target in the e2fsck directory now sets
1995LD_LIBRARY_PATH before running the various e2fsck internal library
1996regression tests.
1997
1998The crc32 regression test in the e2fsck library is now portable to
1999greater varienty of environments, including big-endian systems and
2000when cross-building e2fsprogs for embedded systems.  (Addresses
2001Sourceforge Bug: #2019287)
2002
2003The ext2fs_extent_set_bmap() had some bugs when setting the first
2004block in a file, or when replacing a single block extent.  Those cases
2005fortunately were came up relatively rarely when e2fsck was checking
2006files, but caused some problems when resize2fs was shrinking
2007extent-based files.
2008
2009Fix a potential core-dumping bug in libe2p's iterate_on_dir()
2010function.
2011
2012Various ext2fs library functions --- ext2fs_block_iterate2(),
2013ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
2014allocated memory to avoid memory leaks in all of their error return
2015paths.
2016
2017Ext2ed was failing to build because masix support had been removed in
2018the rest of e2fsprogs, so ext2ed no longer has masix support, either.
2019
2020The configure script now respects the LDFLAGS environment variable if
2021it is set when configure is called.  (Addresses Sourceforge Feature
2022Request: #1937287)
2023
2024Libuuid is now more portable to the Windows platform.  (Addresses
2025Sourceforge Feature Request: #1937287)
2026
2027The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2028bare echo commands so that configure flags such as --quiet work
2029correctly.  (Addresses Sourceforge Patches: #2058794)
2030
2031A few uses of sprintf have been removed from the ext2fs library to
2032make life easier for bootloaders with a limited libc environment.
2033(Addresses Sourceforge Bug: #2049120)
2034
2035The ext2fs_read_inode() checks the validity of the inode number passed
2036to it earlier, to avoid doing some needless work when it would fail
2037anyway.
2038
2039The ext2fs_open() checks the validity of the blocksize parameter
2040passed to it earlier, to avoid doing some needless work when it would
2041fail anyway.
2042
2043Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2044top-level Makefile.  That automatic rule is used to better support
2045SCCS, but it caused problems for a particular niche distribution which
2046likes to use configure.sh files to store the configure options used to
2047build a package.  Unfortuntaely GNU make will use the configure.sh to
2048replace the configure script, resulting in a self-inflicted fork bomb
2049leading to an out-of-memory crash.
2050
2051To support old GNU C compilers don't use C99/C++ comments, but only
2052K&R style comments, and don't try to use __builtin_expect if __GNUC__
2053is less than 3.  (__builtin_expect is only supported for gcc versions
20542.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2055this is an optimization, we only try to use __builtin_expect for gcc 3
2056and up.)
2057
2058In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2059__LITTLE_ENDIAN, which are only defined by glibc's header files and
2060hence isn't portable.
2061
2062For the convenience for some distributions that need a static tune2fs,
2063the Makefile for misc/ now has a tune2fs.static target.
2064
2065The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2066for extent-based files
2067
2068The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2069files.
2070
2071All source files no longer have any trailing white space.
2072
2073The io_channel_read_blk64() and io_channel_write_blk64() functions are
2074now functions instead of C preprocessor macros to provide better
2075forward compatibility.
2076
2077The e2fpsrogs translation template now expands the @x abbrevation.
2078
2079Various namespace leackages in libblkid, libe2p, and libext2fs have
2080been fixed.
2081
2082Fix a parallel build problem in e2fsprogs.
2083
2084E2fsprogs is now more portable to Solaris.
2085  * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
2086    are always present.
2087  * Scripts do not assume that /bin/true is always in /bin
2088  * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2089  * Flush stdio handles before calling setbuf(), since Solaris will
2090    discard any pending output to the stream.
2091  * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2092    picky about which C compiler can beused for SUSv3 conformance.
2093    Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2094    and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2095    Since we need some SUSv3 functions, consistently use SUSv3 so
2096    that e2fsprogs will build on Solaris using c99.
2097  * Solaris C99 does not support varargs C preprocessor macros
2098  * Solaris header files pollute the C namespace if in/netinet.h
2099    is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2100    typedef.
2101  * Solaris ships with a pathetically ancient shell in /bin/sh so we
2102    avoid the use of various more avanced shell constructs such as $().
2103
2104The "make rpm" command will now take some extra configure optiosn from
2105the build environment without needing to patch the source tree.
2106
2107The ext2fs_add_dir_block() function will now grow the dblist more
2108aggressively as an optimization to avoid copying the array too often.
2109
2110The e2fsck_write_bitmaps() will write the block and inode bitmaps
2111together instead of in two passes.
2112
2113
2114E2fsprogs 1.41 (July 10, 2008)
2115==============================
2116
2117Add support for ext4 filesystem features, in particular extents,
2118uninit_bg, flex_bg, huge_file, and dir_nlink features.  Also add
2119support for checking journal checksums.  Debugfs will print new
2120superblock and inode fields that were defined for ext4.  For example,
2121the nanosecond and i_version fields of an inode, and the
2122s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2123Note: Resize2fs doesn't currently support the combination of flex_bg
2124and !resize_inode.  (Addresses Debian Bug: #388452, #425477)
2125
2126Tune2fs can support migrating a filesystem from using 128 byte inodes
2127to 256 byte inodes, so it can take advantage of the full features of
2128ext4.
2129
2130Add support for "undo" support.  E2fsck and mke2fs can optionally
2131record an undo log which can replayed by the program e2undo.
2132
2133E2fsck could damage a filesystem by trying to relocate inode tables
2134due to corrupted block group descriptors, where the attempted inode
2135table relocation would do far more harm than good.  E2fsck has been
2136fixed to detect this these sorts of corrupted block group descriptors
2137much earlier in e2fsck processing, so it can try to use the backup
2138superblock and block group descriptors first.  This should be a much
2139better strategy for recovering these types of corrupted filesystems.
2140(Addresses Sourceforge Bug: #1840291)
2141
2142E2fsck will display a more understandable message when the last check
2143field in the superblock is in the future.  (Addresses Debian Bug:
2144#446005).
2145
2146E2fsck now performs more extensive and careful checks of extended
2147attributes stored in the inode.
2148
2149Enhance mke2fs to print a more explanatory error message when
2150ext2fs_get_device_size() returns EFBIG.  (Addresses Debian Bug:
2151#488663)
2152
2153Fix mke2fs to use a default block size of 4k when formatting an
2154external journal device.  This is done by using a fixed filesystem
2155type list that consists only of the single filesystem type "journal"
2156when looking up configuration keys in /etc/mke2fs.conf.  (Addresses
2157Debian Bug: #488663)
2158
2159Speed up how mke2fs writes the journal data blocks by writing the disk
2160blocks in larger chunks.
2161
2162Fix blkid handling of stale devices.  Fix a bug which could cause a
2163core dump while garbage collecting the blkid cache, and assure that
2164blkid_find_dev_with_tag() never returns a non-existent device.  Also,
2165if a filesystem is found at a new /dev location, eliminate any
2166duplicate stale entries which can not be verified.
2167(Addresses Debian Bugs: #487758, #487783)
2168    
2169Add more paranoid checks for LVM volumes and swap partitions in
2170blkid's probe function, to reduce the chances of false positives.
2171
2172The mke2fs program now has a much more sophisticated system for
2173controlling configuration parameters of a newly created filesystem
2174based on a split filesystem and usage type system.  The -t option to
2175mke2fs was a deprecated alias to -c; it now specifies a filesystem
2176type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2177separated usage list.  The filesystem type information and type
2178information is used to extract configuration parameters from the
2179/etc/mke2fs.conf file.
2180
2181The mke2fs program will no longer complain and request the -f option
2182when the user tries to create a filesystem with greater than 2**31
2183blocks.
2184
2185When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2186adjust the mke2fs.conf file so filesystems for the Hurd are created
2187with a blocksize of 4096 and inode size of 128, which is all it knows
2188how to handle.  (Addresses Debian Bug: #471977)
2189    
2190Mke2fs will always make sure that lost+found always has at least 2
2191blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2192
2193Resize2fs will now print the minimum needed filesystem size if given
2194the -P option, and will resize the filesystem to the smallest possible
2195size if given the -M option.
2196
2197Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2198blocks are consumed during an off-line resize.
2199
2200The "ls" command in debugfs now supports the -p option, which causes
2201it to quote the filenames so that spaces or tabs in directory entries
2202are easily visible.  (Addresses Red Hat Bugzilla: #149480; Addresses
2203Sourceforge Feature Request: #1201667)
2204
2205Fix a potential off-by-one buffer oveflow in the fs_device_name in an
2206e2image file.
2207
2208The chattr program will return a non-zero exit code in case of
2209failures, and error messages can be suppressed with the -f option.
2210(Addresses Red Hat Bugzilla: #180596)
2211
2212Fix a bug in badblocks which caused it to overrun an array and likely
2213crash if more than 8 test patterns are specified using the -t option.
2214(Addresses Debian Bug: #487298)
2215    
2216Add support to badblocks to limit how quickly it reads from the disk
2217drive (so it can be used for background scrubbing), and so it will
2218abort after finding a given number of errors.
2219
2220Remove support for the legacy big-endian filesystem format which only
2221existed on extremely long-dead PowerPC kernels almost a decade ago.
2222
2223Remove MASIX support from e2fsprogs.
2224
2225Add I/O statistics reporting to e2fsck.
2226
2227Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
2228Czech translations.
2229
2230Fixed various Debian packaging issues --- see debian/changelog for
2231details.  (Addresses Debian Bugs: #487443, #487675, #490003)
2232
2233Fixed spelling mistakes, typos, and otherwise clarified man pages.

2236Programmer's Notes
2237------------------
2238
2239Factor out bitmap code in preparation for adding 64-bit new-style
2240bitmaps.
2241
2242Fix gcc -Wall warnings
2243
2244Fix the pkg-config files so that private librares are specified in
2245"Libs.private:".
2246
2247Fix the libext2fs.texinfo manual so it builds with modern versions of
2248texinfo.
2249

2251
2252Clean up the badblocks group so to make it more portable and robust.
2253
2254Avoid using predictable filenames in /tmp in blkid's regression test
2255suite.  Also remove bashism's in the regression test script.
2256
2257If the configure script is given --with-diet-libc, don't use thread
2258local storage, since diet libc doesn't support TLS.  (Addresses
2259Sourceforge Bug: #2000654)
2260    
2261Fix the blkid regression test suite to tolerate older versions of
2262mkswap that don't support the -U option.
2263
2264A few library routines have been converted to support 64-bit block
2265numbers; in particular, the I/O manager functions, the test_io,
2266inode_io, and unix_io managers have all be converted to support 64-bit
2267operation.
2268
2269Debugfs can now be extended for use by test programs.  See
2270lib/ext2fs/extents.c for an example for how it can be used.  The test
2271program links against the debugfs object files, and provides
2272additional commands by defining an auxiliary libss command table.
2273
2274The lazy_bg filesystem feature, which was only used by developer's
2275testing, has been removed since it has been largely supplanted by
2276uninit_bg.  This also simplifies the code.
2277

2298Fix marginal C code in probe_lvm2() function to the blkid library more
2299portable for older compilers.
2300
2301Fix build problems on MacOS X.  (Addresses Sourceforge Bug: #1972473)
2302
2303Fix ext2fs_swap{16,32,64} functions so they can be used by external
2304applications on big-endian machines.  (Addresses Debian Bug: #484879)
2305    
2306
2307E2fsprogs 1.40.10 (May 21, 2008)
2308================================
2309
2310When deciding whether or not to revalidate a blkid cache entry, if the
2311device's mtime is newer than the last time the cached entry was
2312validated, force a revalidation.
2313
2314Fix a potential data corruption bug in e2fsck in the journal replay.
2315The chances of this is happening is extremely remote, especially the
2316default data=ordered or data=writeback modes.  However, if a block
2317which has been journalled starts with the first four bytes 0xc03b3998,
2318when e2fsck replays the journal, those four bytes will be replaced
2319with zero's.  Fortunately, it is highly, highly unlikely for e2fsck
2320metadata to begin with those fatal 4 byte sequence, and unless
2321data=ordered mode is in use, data blocks are never journaled.
2322
2323Updated German, Dutch, Sweedish, and Vietnamese translations.

2335E2fsprogs 1.40.9 (April 27, 2008)
2336=================================
2337
2338SuSE's security team audited uuidd and came up with a few minor
2339issues.  None of them are serious given that uuidd runs setuid as a
2340unprivileged user which has no special access other than libuuid
2341directory, but it's good to get them fixed.
2342
2343One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
2344work correctly with in-inode extended attributes.
2345
2346Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
2347translations.
2348
2349Debugfs will avoid using a pager if the standard output is not a tty.
2350
2351Fix debugfs and tune2fs to correctly handle daylight savings time when
2352parsing a time string.
2353
2354Fixed spelling mistakes, typos, and otherwise clarified man pages.
2355
2356Fix fsck completion bars when multiple filesystems were being checked
2357in parallel.  (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
2358#203323, Addresses Sourceforge Bug: #1926023)
2359
2360Fix fsck so that progress information is sent back correctly when
2361multiple filesystems are being check and the output of fsck is being
2362redirected to a file descriptor.  Also, include the device name (w/o
2363spaces) in the progress information sent back via a file descriptor.
2364(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:

2366
2367Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
2368
2369If logsave receives a SIGTERM or SIGINT signal, it will now pass that
2370signal to its child process.
2371
2372Fix mke2fs's creation of are resize inode when there is a non-standard
2373s_first_data_block setting.

2375Fix bug in blkid when run by an unprivileged user; most devices were
2376not reported correctly.  9Addresses Launchpad Bug: #220275)
2377
2378Mke2fs will not allow the logically incorect combination of
2379resize_inode and meta_bg, which had previously caused mke2fs to create
2380a corrupt fileystem.

2405E2fsprogs 1.40.8 (March 13, 2008)
2406=================================
2407
2408Fixed e2image -I so it works on image files which are larger than 2GB.
2409
2410Fixed e2fsck's handling of directory inodes with a corrupt size field.  If
2411the size is larger than the number of blocks found in the inode, don't
2412try to allocate extra empty blocks at the end of the directory to make
2413up the difference; there's no point to doing that.  In addition, if
2414the size is not a multiple of a blocksize, always fix it.
2415
2416E2fsck handled a pass 2 "should never happen error" by not giving
2417enough information and then core dumping.  Unfortunately, it was all
2418too easy to trigger the "should never happen" situation if a
2419directory's inode size was not correct.  This has been fixed, but
2420e2fsck has also been taught how to handle this situation more
2421gracefully, by simply removing the inode hash tree information, so
2422that it can be rebuilt again after e2fsck's pass 3.  (Addresses
2423Launchpad Bug: #129395)

2425Resize2fs had a bug resizing large inodes with extended attributes
2426that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2427completely on big-endian systems such as PowerPC.  The bug should be
2428completely fixed now.  Yay for regression test suites.  (Addresses Red
2429Hat Bugzilla: #434893)
2430    
2431Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
2432translations.  Many thanks to Philipp Thomas from Novell for stepping
2433up to become the new German translation maintainer!  (Addresses Debian
2434Bugs: #302512, #370247, #401092, #412882).
2435
2436When e2fsck is clearing a corrupt inode's HTREE directory information,
2437make it clear that it is just clearing the HTREE information, not the
2438entire inode.
2439
2440Fixed spelling mistakes, typos, and otherwise clarified man pages.  
2441
2442Programmer's notes
2443------------------
2444
2445Add new functions, ext2fs_dblist_get_last() and
2446ext2fs_dblist_drop_last(), which allows the caller to examine the last
2447directory block entry added to the list, and to drop if it necessary.
2448
2449Fixed a portability problem in libblkid with DJGPP.
2450
2451Fix an obvious typo in an "internal error" message in e2fsck.  Thanks
2452to Philipp Thomas for pointing this out.
2453
2454If the info files are not built, change "make install" so it doesn't
2455fail with an error code.

2457
2458E2fsprogs 1.40.7 (February 28, 2008)
2459====================================
2460
2461Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2462depreciate the -s option, since it can result in filesystems which
2463e2fsck can't fix easily.  There are very good reasons for wanting to
2464disable sparse_super; users who wants to turn off sparse_super can use
2465debugfs.  (Addresses Sourceforge Bug: #1840286)
2466    
2467Add missing options to mke2fs's usage message.  (Addresses Sourceforge
2468Bug: #1751393)
2469    
2470Fix bug in resize2fs when large (greater than 128 byte) inodes are
2471moved when a filesystem is shrunk; it was only moving the first 128
2472bytes, so extended attributes were not getting moved.  (Addresses Red
2473Hat Bugzilla: #434893)
2474
2475E2fsck now prints an explicit message when the bad block inode is
2476updated, to avoid confusion about why the filesystem was modified.
2477(Addresses Sourceforge Bug: #756460)
2478    
2479Allow mke2fs and tune2fs manipulate the large_file feature.
2480Previously we just let the kernel and e2fsck do this automatically,
2481but e2fsck will no longer automatically clear the large_file feature.
2482It still isn't really necessary to worry about this feature flag
2483explicitly, but some users seem to care.  (Addresses Red Hat Bugzilla:
2484#258381)
2485    
2486Suppress message about an old-style fstab if the fstab file is empty.
2487(Addresses Debian Bug: #468176)
2488    
2489Fix (really minor) bug in debugfs's find_free_block so it avoids
2490reporting a free block more than once if there are too few free blocks
2491in the filesystem.  (Addresses Sourceforge Bug: #1096315)
2492    
2493Change e2fsck to no longer clear the LARGE_FILES feature flag
2494automatically, when there are no more > 2GB files in the filesystem.
2495It's been almost a decade since there have been kernels that don't
2496support this flag, and e2fsck clears it quietly without telling the
2497user why the filesystem has been changed.
2498    
2499Fix bug which could cause libblkid to seg fault if a device mapper
2500volume disappears while it is being probed.  (Addresses RedHat
2501Bugzilla: #433857)
2502    
2503Inhance e2fsck's reporting of unsupported filesystem feature flags.
2504(Addresses Sourceforge Feature Request: #1175808)
2505    
2506Fix option syntax in dumpe2fs for explicit superblock and blocksize
2507parameters.  What was currently documented in the man page has been
2508broken for some time, due to getopt() implementation changes.  The
2509option sytax has been changed to one which is can be more portable
2510supported and which is consistent with the format for extended options
2511in mke2fs and tune2fs.  (Addresses Sourceforge Bug: #1830994)
2512    
2513Add support to tune2fs to clear the resize_inode feature.  This
2514requires an fsck afterwards.  (Addresses Red Hat Bugzilla: #167816)
2515
2516Teach blkid to detect LVM2 physical volumes.  (Addresses Red Hat
2517Bugzilla: #409321)
2518
2519Add support for setting RAID stride and stripe-width via mke2fs and
2520tune2fs.  Teach dumpe2fs to print the RAID parameters.
2521
2522Add support for setting new superblock fields to debugfs's
2523set_super_value.
2524
2525Add support for printing "mostly-printable" extended attributes in
2526Debugfs.
2527
2528Add support for the -M option to fsck, which causes it to ignore
2529mounted filesystem.
2530
2531Fix uuidd so that it creates the pid file with the correct pid number.
2532(Addresses Sourceforge Bug: #1893244)
2533
2534Fix various gcc -Wall warnings.

2544
2545Fixed various Debian packaging issues --- see debian/changelog for
2546details.  (Addresses Debian Bug: #466929)
2547
2548Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
2549partially filled-in filesystem object on an error, so that e2fsck can
2550print more intelligent error messages.
2551    
2552Add a new function e2p_edit_feature2() which allows the caller to
2553specify which feature flags are OK to set or clear, and which returns
2554more specific information about feature flags which are not allowed to
2555be set/cleared.

2593Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.

2608Don't try to create $DESTDIR/etc/init.d as part of make install as we
2609don't install the init.d script (and it's not the recommended way to
2610start uuidd anyway).  (Addresses Sourceforge Bug: #1885085)
2611
2612Use thread local storage to fix a theoretical race condition if two
2613threads try to format an unknown error code at the same time in the

2615
2616
2617E2fsprogs 1.40.5 (January 27, 2008)
2618===================================
2619
2620Fix a potential overflow big in e2image if the device name is too
2621long.
2622
2623Mke2fs will now create new filesystems with 256 byte inodes and the
2624ext_attr feature flag by default.  This allows for much better future
2625compatibity with ext4 and speeds up extended attributes even on ext3
2626filesystems.
2627
2628Teach e2fsck to ignore certain "safe" filesystem features which are
2629set automatically by the kernel.  Having the kernel set features
2630automagically behind the user's back is a bad idea, and we should try
2631to break the kernel of this habit, especially for the newer ext4
2632feature flags.  But for now, we will try to avoid needless full checks
2633which can annoy users who are doing fresh installs.
2634
2635Add support in tune2fs and mke2fs for making a filesystem as being "ok
2636to be used with test kernel code".  This will be needed for using test
2637filesystems with the latest ext4 kernel code.
2638
2639Change e2fsck -fD so that it sorts non-htree directories by inode
2640numbers instead of by name, since that optimizes performances much
2641more significantly.  (Addresses-Sourceforge-Feature-Request: #532439)
2642
2643If e2image fills the disk, fix it so it exits right away instead of
2644spewing large numbers of error messages.
2645(Addresses-Sourceforge-Feature-Request: #606508)
2646
2647If ftruncate64() is not available for resize2fs, let it use ftrucate()
2648instead, but have it check to see if the size would get truncated, and
2649skip calling ftruncate in that case.
2650
2651Add support for detecting HFS+ filesystems in the blkid library.
2652
2653Add supprt in the blkid library for ext4/ext4dev filesystems.
2654
2655Fix a bug in blkid where it could die on a floating point exception
2656when presented with a corrupt reiserfs image.
2657
2658Fix blkid's handling of ntfs UUID's so that leading zeros are printed
2659such that UUID string is a fixed length.
2660
2661Add sample python bindings for the uuid library to the contrib
2662directory.  (Addresses-Sourceforge-Patches: #778817)
2663
2664Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
2665will work with large files.  (Addresses Sourceforge Feature Request:
2666#1257500 and Sourceforge Support Request: #1253511)
2667    
2668Allow the debugfs 'undel' command to undelete an inode without linking
2669it to a specific destination directory, since this might require
2670allocating blocks that could overwrite some yet-to-be-recovered
2671deleted files.  (Addresses-Sourceforge-Feature-Request: #967141)

2709Improve time-based UUID generation.  A new daemon uuidd, is started
2710automatically by libuuid if necessary.  This daemon is setuid to allow
2711updates to /var/lib/libuuid, so the clock sequence number can be
2712stored and so if the clock is set backwards, it can be detected.

2715
2716Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2717superblocks.  This avoids e2fsck from concluding that a full
2718filesystem check is required before backing up the superblock due to
2719changes in the feature flags.  (Addresses Debian Bug: #454926)
2720
2721Fix fsck to only treat the '#' character as a comment at the beginning
2722of the line in /etc/fstab.  Otherwise fstabs for the fuse filesystem
2723will cause fsck to issue an bogus warning message.

2761E2fsprogs 1.40.3 (December 5, 2007)
2762===================================
2763
2764Fix a potential security vulnerability where an untrusted filesystem
2765can be corrupted in such a way that a program using libext2fs will
2766allocate a buffer which is far too small.  This can lead to either a
2767crash or potentially a heap-based buffer overflow crash.  No known
2768exploits exist, but main concern is where an untrusted user who
2769possesses privileged access in a guest Xen environment could corrupt a
2770filesystem which is then accessed by the pygrub program, running as
2771root in the dom0 host environment, thus allowing the untrusted user to
2772gain privileged access in the host OS.  Thanks to the McAfee AVERT
2773Research group for reporting this issue.  (Addresses CVE-2007-5497.)
2774
2775Fix hueristics in blkid which could cause a disk without partitions to
2776be incorrectly skipped when a loopback device is present.  (Addresses
2777Red Hat Bugzilla #400321.)
2778
2779Fix e2image so that in raw mode it does not create an image file which
2780is one byte too large.
2781
2782Change mke2fs's usage message so it recommends the preferred -E option
2783instead of the deprecated -R option.
2784
2785Enhance the blkid library so it will recognize squashfs filesystems.
2786(Addresses Red Hat Bugzilla #305151.)
2787
2788Enhance e2fsck so it will force the backup superblocks to be backed up
2789if the filesystem is consistent and key constants have been changed
2790(i.e., by an on-line resize) or by e2fsck in the course of its
2791operations.
2792
2793Enhance blkid's detection of FAT filesystems; so that USB disks with
2794only a single bootable partition will not get missed.
2795
2796E2fsck will no longer mark a filesystem as invalid if it has time
2797errors (i.e., if superblock mount time or last write time is in the
2798future) and the user refuses to fix the problem.
2799
2800The Ubuntu init scripts don't properly set the system time correctly
2801from hardware clock if the hardware clock is configured to tick local
2802time instead of GMT time.  Work around this as best as we can by
2803providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2804be set on Ubuntu systems.  (Addresses Debian Bug #441093, and Ubuntu
2805Bug #131201.)
2806
2807Fix fsck to ignore /etc/fstab entries for bind mounts.  (Addresses Red
2808Hat Bugzilla #151533.)
2809
2810Fix e2fsck so that if the superblock is corrupt, but still looks
2811vaguely like an ext2/3/4 superblock, that it automatically tries to
2812fall back to the backup superblock, instead of failing with a hard
2813error.
2814
2815Make the e2fsprogs program more robust so that they will not crash
2816when opening a corrupt filesystem where s_inode_size is zero.
2817
2818Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2819arguments are detected as such and the parse error is reported to the
2820user.   (Addresses Debian Bug #435381.)
2821
2822Change e2fsck so it will not complain if a file has blocks reallocated
2823up to the next multiple of a system's page size.
2824
2825Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2826about (valid) filesystems where the inode table extends to the last
2827block of the block group.  (Addresses Red Hat Bugzilla #214765.)
2828
2829Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2830allocating inode tables for some relatively rare odd disk sizes.
2831(Addresses Red Hat Bugzilla #241767.)
2832
2833Add Catalan translation and update Dutch and Swedish translations
2834from the Translation Project.
2835
2836Fix big-endian byte-swapping bug in ext2fs_swap_inode_full().  We
2837still had an issue when trying to figure out whether we need to
2838byte-swap fast symlinks that contained extended attributes.

2850
2851Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2852works correctly when the prefix is not the root directory.
2853
2854Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2855clena up after themselves by deleting the test.img temporary file
2856after completing the test.
2857
2858Fixed a corner case bug ext2fs_unlink() when trying to delete the
2859first directory entry in a directory block and the last directory
2860entry in the previous directory block is not in use.  Fortunately
2861ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2862places where it is extremely unlikely to run into this corner case.
2863
2864Fix missing dependency which would cuase parallel builds to fail.
2865(Addresses Sourceforge Bug #1842331.)

2875are properly passed back up through the call stack.
2876
2877E2fsprogs 1.40.2 (July 12, 2007)
2878================================
2879
2880A recent change to e2fsck_add_dir_info() to use tdb files to check
2881filesystems with a very large number of filesystems had a typo which
2882caused us to resize the wrong data structure.  This would cause a
2883array overrun leading to malloc pointer corruptions and segfaults.
2884Since we normally can very accurately predict how big the the dirinfo
2885array needs to be, this bug only got triggered on very badly corrupted
2886filesystems.
2887
2888Fix a bug in e2fsck which caused it to incorrectly salvange
2889directories when the last entry's rec_len is bogusly too big.  This
2890resulted in a nonsense filesystem corruption to be reported, and
2891required a second run of e2fsck to fully fix up the directory.
2892

2900E2fsprogs 1.40.1 (July 7, 2007)
2901===============================
2902
2903Fix bug which could cause libblkid to loop forever.  When revalidating
2904a partition where there is obsolete information in /etc/blkid.tab, we
2905end up freeing a the type tag without clearing dev->bid_type, causing
2906blkid_verify() to loop forever.  (Addresses Debian Bug: #432052)
2907    
2908The Turkish translation has a bug in it where it has the translation
2909of "E@e '%Dn' in %p (%i)" to "E@E".  This causes @E to be expanded at
2910@E, recursively, forever, until the stack fills up and e2fsck core
2911dumps.  We fix this by making e2fsck stop @-expansions after a
2912recursive depth of 10, which is far more than we need.
2913(Addresses Sourceforge Bug: #1646081)
2914    
2915Compile the default mke2fs.conf into mke2fs program.  People are
2916getting surprised by mke2fs creating filesystems with different
2917defaults than earlier versions of mke2fs if mke2fs.conf is not
2918present.  So we now create a built in version of mke2fs.conf file
2919which is used by mke2fs if the /etc/mke2fs.conf is not present.
2920(Addresses SourceforgeBug: #1745818)
2921
2922Improve the config/parse_types.sh helper script.  Fix a potential
2923security problem if e2fsprogs is built as root (as Gentoo does!).  In
2924addition fix the script and how it is called from the configure script
2925so that it does the right thing when cross-compiling.  (Fixes Gentoo
2926bug: #146903)
2927    
2928Update Vietnamese, French, and Dutch PO files from the Translation
2929Project.  Also created a new e2fsprogs.pot file for translator.
2930    
2931Fix bogus strip permission errors when building under Debian.  When
2932building the e2fsprogs dpkg's, the dh_strip command emits a large
2933number of error messages caused by the permissions not being right.
2934So run dh_fixperms before running dh_strip.
2935
2936Programmer's Notes:
2937-------------------
2938
2939Add new function: profile_set_default().  This function sets the value
2940of the pseudo file "<default>".  If the file "<default>" had
2941previously been passed to profile_init(), then def_string parameter
2942will be parsed and used as the profile information for the "<default>"
2943file.
2944    
2945Fix mk_cmds's error reporting so that it is unambiguous that it is the
2946mk_cmds script which is generating the error.  (Obviates Gentoo patch:
2947e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2948    
2949Fix the test suite to use LC_ALL instead of LANG.  LC_ALL is the "high
2950priority" environment variable that overrides all others, where as
2951LANG is the lowest priorty environment variable.  If LC_ALL is set, it
2952doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2953the all the rest are set.  This will assure that the locale when
2954running the test suites is the "C" locale.  (Obviates Gentoo patch:
2955e2fsprogs-1.38-tests-locale.patch)
2956    
2957
2958E2fsprogs 1.40 (June 29, 2007)
2959==============================
2960
2961Fix divide by zero error in blkid's NTFS probing logic.
2962
2963Add new blkid -g option which causes the blkid cache to be garbage
2964collected.
2965
2966Fix a bug in libblkid which could cause the internal field bid_type to
2967become corrupted.  Fortunately bid_type isn't used much, and bid_label
2968and bid_uuid is only used by debugging code, so the impact of this bug
2969was very minor.
2970
2971Mke2fs will now store the RAID stride value when a filesystem is
2972created with a requested RAID stride, and then use it automatically in
2973resize2fs.
2974
2975Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2976isn't too big.  In some cases Lustre users have tried specifying an
2977inode size of 4096 bytes, while keeping an inode ratio of one inode
2978per 4096 bytes.  
2979
2980Improve sanity check in e2fsck's algorithm for finding a backup
2981superblock, so that it won't accidentally find a superblock that was
2982located in the journal, and then later reject it as being not a valid
2983backup superblock.
2984
2985Fix e2fsck get_size logic so that it will work with the Linux floppy
2986driver.  The Linux floppy driver is a bit different from the other
2987block device drivers, in that if the device has been opened with
2988O_EXCL, it disallows another open(), even if the second open() does
2989not have the O_EXCL flag.  (Addresses Debian Bug: #410569)
2990
2991Fix error checking of badblock's last-block and start-block arguments.
2992(Addresses Debian Bug: #416477)
2993
2994Fix e2fsck so that it doesn't overwrite the backup superblocks when
2995recovering a journal until the master superblock has been confirmed as
2996being sane.
2997
2998Change the blkid library to be much more paranoid about concluding
2999that a partition contains an NTFS filesystem, and fetch the UUID and
3000LABEL information from NTFS filesystems.  (Addresses Launchpad Bug:
3001#110138)
3002
3003Factor out the code which sets the default journal size and move it
3004into libext2fs.
3005
3006Enhance e2fsck so it will recreate the ext3 journal if the original
3007journal inode was cleared to due it being corrupt after finishing the
3008filesystem check.
3009
3010Fix e2fsck so that it updates the journal inode if it is corrupted and
3011the backup journal information from the superblock was successfully
3012used to recover the filesystem.
3013
3014Fix e2fsck so that it checks all of the blocks in the journal inode
3015for validity.  The original code only checked the direct blocks to
3016make sure the journal inode was sane.  Unfortunately, if some or all
3017of the indirect or doubly indirect blocks were corrupted, this would
3018not be caught.
3019
3020Add support in blkid to detect LUKS encrypted partitions.
3021
3022Add extra sanity checks for extended attributes in the case where the
3023size is zero but the offset is very large.
3024
3025Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3026and ext2fs_get_next_inode_full().
3027
3028Clarify the copyright licenses used by the various libraries in
3029the top-level COPYING  file (Red Hat Bugzilla: 166058)
3030
3031Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3032
3033Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3034
3035Remove check in e2fsck which requires EA's in inodes to be sorted;
3036they don't need to be sorted, and e2fsck was previously wrongly
3037clearing unsorted EA's stored in the inode structure.
3038
3039Allow mke2fs or tune2fs to create a substantially larger journal (up
3040to 10,240,000 blocks).
3041
3042Fix MD superblock detection, and make sure the correct UUID is
3043reported from the MD superblock.
3044
3045Fix a signed vs. unsigned bug in debugfs.
3046
3047Enhance debugfs's date parser so that it accepts integer values.
3048
3049Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3050file with multiply claimed blocks is hard linked. or not at all if the
3051root directory contains shared blocks
3052
3053Enhance debugfs so it can modify the block group descriptors using the
3054command set_block_group_descriptor.
3055
3056Improve e2fsck's reporting of I/O errors so it's clearer what it was
3057trying to do when an error happens
3058
3059Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3060symlinks that have extended attributes.  (Addresses Red Hat Bugzilla:
3061#232663 and LTC Bugzilla: #27634)
3062
3063Fix potential file descriptor leak in ext2fs_get_device_size() in an
3064error case.
3065
3066Add libreadline.so.5 support to libss.
3067
3068Impove badblocks -n/-w exclusive usage message.
3069
3070Fix dump_unused segfault in debugfs when a filesystem is not open
3071
3072Fix memory leak in blkid library.  (Addresses Debian Bug: #413661)
3073
3074Allow the debugfs lcd command to work w/o a filesystem being open.
3075(Addresses LTC Bugzilla #27513)
3076
3077Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3078field on the first pass.
3079
3080Fix e2fsck to set the file type of the '..' entry when connecting
3081a directory to lost+found.  (Addresses Lustre Bug: #11645)
3082
3083Enhance e2fsck to recover directories whose modes field were corrupted
3084to look like special files.  This is probably only useful in
3085artificial test cases, but it will be useful if we ever do the "inodes
3086in directory" idea for ext4.
3087
3088Allow debugfs to dump (and rdump) > 2GB files.  (Addresses Debian Bug:
3089#412614)
3090
3091Fix resize2fs parsing of size parameter (in sector units).  This was
3092actually a bug in libe2p's parse_num_blocks() function.  When handling
3093the 's' suffix, it was ignoring the blocksize information passed in
3094from the caller and always interpreting the number in terms of a 1k
3095blocksize.  (Addresses Debian Bug: #408298)
3096
3097There was a floating point precision error which could cause e2fsck to
3098loop forever on really big filesystems with a large inode count.
3099(Addresses Debian Bug: #411838)
3100
3101Fix memory leak in ext2fs_write_new_inode()
3102
3103Add support for using a scratch files directory to reduce e2fsck's
3104memory utilization on really big filesystems.  This uses the TDB
3105library.  See the [scratch_files] section of the e2fsck.conf man page
3106for more details.
3107
3108Fixed type-punning bug which caused dumpe2fs to crash on the Arm
3109platform (Addresses Debian Bug: #397044)
3110
3111Add explanatory message to badblocks that -n and -w are mutually exclusive
3112(Addresses Debian Bug: #371869)
3113
3114Allow debugfs and dumpe2fs to support fs features under development.
3115
3116Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3117ext2fs_open() , which allows application to open filesystes with features
3118which are currently only partially supported by e2fsprogs.
3119
3120Allow unix_io to support offsets greater than 2G (Addresses
3121SourceForge Bug: #1547922)
3122
3123Fixed overflow and signed/unsigned problems caused by the number of
3124blocks or inodes exceeding 2**31 or being close to 2**32-1.
3125
3126Add support for unsigned directory hash calculations with hints in the
3127superblock to fix cross-architectural portability for htree
3128directories with filenames where the high 8th bit is set.  (Addresses
3129Debian: #389772)
3130
3131Fix resize2fs so that it gives user-intelligible error messages if the
3132filesystem or the kernel does not support on-line resizing.
3133(Addresses Debian Bug: #380548)
3134
3135Require mke2fs -F -F for really dangerous operations, since -F is
3136needed for less dangerous operations such as creating filesystems
3137images in regular files, or creating filesystems on whole block
3138devices.  These relatively innocuous usages should NOT be confused
3139with running mke2fs on an apparently-mounted or in-use filesystem.
3140
3141Allow the default inode size to be specified into the mke2fs.conf
3142file.
3143
3144Make the smallest default journal size is big enough so that on-line
3145resizing should always work.
3146
3147Fix silly spelling error in e2fsck.  (Addresses SourceForge bug:
3148#1531372)
3149
3150Fix debugfs coredump when lsdel is run without an open filesystem
3151(Addresses Debian Bug: #378335)
3152
3153Fix debugfs display bug us that bytes that have the high bit set are
3154displayed as "ec" instead of "ffffffec".
3155
3156Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3157
3158Device mapper scanning wasn't working in the blkid library because the
3159pathnames had an extra "/dev" when they were being probed.
3160
3161Add GFS/GFS2 support to the blkid library.
3162
3163Fix blkid support of empty FAT filesystem labels.
3164
3165Avoid recursing forever (or for a long time) when the blkid library
3166searches for a device and there are symlinks to directories in /dev.
3167
3168Avoid unaligned halfword access in blkid when accessing FAT
3169superblocks, as this will cause Sparc/Solaris systems to throw a
3170SIGBUS error.
3171
3172The latest devmapper libraries requires pthreads, add -lpthreads to
3173the static link libraries for e2fsck.static if devmapper is enabled.
3174(Addresses Debian bug: #388718)
3175
3176Improve the (non-installed, for experts only) findsuper program by
3177printing the uuid and label from the superblocks, as well as the
3178starting and ending offsets of the filesystem given the information in
3179the superblock.  Omit by default printing superblocks that are likely
3180found in located in an ext3 journal unless an explicit -j option is
3181given.
3182
3183Updated Spanish, French and Dutch translations and added Catalan
3184translation.  (Addresses Debian bug: #411562)
3185
3186Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3187determining a partition's size, since binary searching to determine
3188the device doesn't work on FreeBSD.
3189
3190Documentation about UUID's is available in enough places, and it's
3191awkward to deal with debian-legal's insanities.  So I'm caving in the
3192"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3193don't have do the dfsg tarball.  Also remove the rule that only tried
3194to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3195e2fsprogs exclusively from Debian.  (Addresses Debian Bug: #407107)
3196
3197Fix the info-dir line so that the menu name does not contain a .info
3198prefix.  First of all, it's ugly, secondly, it causes the install-info
3199command to fail to remove the com_err info file from the
3200/usr/share/info/dir file when the comerr-dev package is removed and
3201purged.  (Addresses Debian Bug: #401711)
3202
3203Fixed spelling mistakes, typos, and otherwise clarified man pages.
3204(Addresses Debian Bug: #369761, #373004, #379695)
3205
3206Fixed various Debian packaging issues --- see debian/changelog for
3207details.  (Addresses Debian Bugs #389554, #390664, #413208, #419605,
3208#408352, #415560, #399155)
3209
3210
3211Programmer's notes:
3212-------------------
3213
3214E2fsck now supports the %It expansion when printing a problem report.
3215It will print the type of the inode in the problem context.
3216
3217Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
3218(Addresses Sourceforge Bug: #1565561)
3219
3220Remove unused variables and other lint/gcc -Wall cleanups
3221
3222Add check to ext2fs_get_device_size() so it will return EFBIG for for
3223filesystems contained in regular files where the filesystem image size
3224is returned by stat64().
3225
3226Set local environment variables to C so mk_cmds and compile_et always
3227work.  (Addresses SourceForge Bug: #1532177)
3228
3229Added the 64-bit byte swapping function ext2fs_swab64().
3230
3231Added two new helper functions to prevent 2**31/2**32-1 overflow
3232problems: ext2fs_div_ceil() and e2p_percent().
3233
3234Create new ext2fs library inline functions ext2fs_group_first_block()
3235and ext2fs_group_last_block() in order to calculate the starting and
3236ending blocks in a block group.
3237
3238Create the generated files read-only to remind developers not to edit them.
3239
3240Add support for autoconf 2.60 (with backwards compatibility for older
3241versions of autoconf).
3242
3243Added an "make rpm" target to top-level Makefile
3244
3245Added various FreeBSD portability fixes.
3246
3247Exclude mercurial files from the RPM build tree to speed up copy/build.
3248
3249Use root_sysconfdir to define the locations of mke2fs.conf and
3250e2fsck.conf instead of using a hard-coded /etc pathname.
3251
3252Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3253
3254Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3255
3256If diff -u is supported, use it to report test failures.
3257
3258Updates/improvements to RPM spec file
3259
3260Add on-disk format definitions for the following new features:
3261EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3262EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3263EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3264
3265Add a new make target "checked-failed" in the tests directory which
3266reruns any failed tests
3267
3268Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3269
3270Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3271pointer dereferences, memory leaks, etc.  None were security-criticial
3272problems.
3273
3274Fix up usage and decrement error messages in the test_icount program
3275
3276Add debugging code to the com_err library; if the environment variable
3277COMERR_DEBUG is set to 1, print out debugging messages as error tables
3278are added and removed from the com_err library.  If the
3279COMERR_DEBUG_FILE environment variable is set (and the process is not
3280setuid) the debugging messages may be redirected to a file.
3281
3282Change all of the e2fsprogs programs to use the newer add_error_table()
3283and remove_error_table() interfaces instead of the much older
3284initialize_*_error_table() function.
3285
3286Add TDB support into the ext2fs library.  This allows us to have a
3287guaranteed library we can count on always being present so we can
3288store data in an on-disk database.
3289
3290Add support for using TDB to store the icount data, so we don't run out
3291of memory when checking really large filesystems.
3292
3293Change the regression test suite so that it skips empty test directories.
3294
3295Define the l_i_iversion field in ext2_inode.  The l_i_version field is
3296now defined from the old l_i_reserved1 field in the ext2 inode.  This
3297field will be used to store high 32 bits of the 64-bit inode version
3298number.
3299
3300Add Makefile production rule for e2fsprogs.spec in case it gets
3301deleted.
3302
3303Add new function profile_get_uint() to allow for a clean way to fetch
3304unsigned integers from the context.
3305
3306Add test to make sure the ext2 superblock structure is 1024 bytes.
3307
3308Fix typo in name of f_dup4 regression test
3309
3310Add new function blkid_gc_cache() which performs a garbage collection
3311pass on the /etc/blkid.tab file.
3312
3313The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY.  In
3314general, only e2fsck (after the filesystem is clean), tune2fs, and
3315resize2fs should change the backup superblocks by default.  Most
3316callers of ext2fs_open() should not be touching any superblock fields
3317which require the backups to be touched.
3318
3319Add new function to libext2fs, ext2fs_default_journal_size(), which
3320returns the default journal size.
3321
3322
3323E2fsprogs 1.39 (May 29, 2006) 
3324=============================
3325
3326Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3327between 2**31 and 2**32 blocks.
3328
3329Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3330configure the filesystem features, blocksize, and inode_ratio for
3331different filesystem types.
3332
3333Mke2fs will now create filesystems hash trees and on-line resizing
3334enabled by default, based on the new /etc/mke2fs.conf file.
3335
3336The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3337filesystem device node in exclusive mode to prevent accidents by
3338system administrators.  In the case of resize2fs and mke2fs, it will
3339only use exclusive mode if the filesystem is not mounted.
3340
3341Fixed a bug in mke2fs which caused it to to fail when creating the
3342resize inode for large filesystems.  (Addresses Debian Bug #346580)
3343
3344When allocating space for the RAID filesystems with the stride
3345parameter, mke2fs will now place each portion of the group's inode
3346table right up after the superblock (if present) in order to minimize
3347fragmentation of the freespace.
3348
3349Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3350efficiently by writing the inode and block bitmaps in one pass, thus
3351reducing the number of disk seeks required.
3352
3353Add support for on-line resizing to resize2fs.
3354
3355Fix blkid library so that logic to determine whether or not a device's
3356cached information in /etc/blkid.tab needs to be verified or not
3357doesn't get confused by a system clock which is insane (for example,
3358if the battery is dead on a Macintosh running PPC Linux.  (Addresses
3359Red Hat Bug: #182188)
3360
3361The blkid library will now store the UUID of the external journal used
3362by ext3 filesystems, so that in the future, the userspace mount binary
3363can use this to find the location of the external journal and pass
3364this information to the kernel.
3365
3366E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3367control how various options should be handled.  See the e2fsck.conf
3368man page for more details.   (Addresses Debian Bug: #150295)
3369
3370E2fsck now prints an explanatory message when delaying a filesystem
3371check when the system is running on battery.  (Addresses Debian Bug:
3372#350306)
3373
3374E2fsck will detect if the superblock's last mount field or last write
3375field is in the future, and offer to fix if so.  (Addresses Debian Bug
3376#327580) These problems will be fixed automatically in preen mode
3377since Debian's boot sequence bogusly doesn't set the time correctly
3378until potentially very late in the bootup process, and this can cause
3379false positives which will cause users' systems to fail to boot.
3380(Addresses Debian Bugs #343662 and #343645)
3381
3382E2fsck now checks to see if the superblock hint for the location of
3383the external journal is incorrect, and if so, offer to update it.
3384(Addresses Debian Bug: #355644)
3385
3386Fix e2fsck from segfaulting on disconnected inodes that contain one or
3387more extended attributes.  (Addresses Debian Bug: #316736, #318463)
3388
3389E2fsck will stop and print a warning if the user tries running a
3390read/write badblocks test on a read-only mounted root filesystem.
3391
3392Fix a memory leak in e2fsck's error paths.  (Thanks to Michael
3393C. Thompson for pointing these out; they were originally found using
3394Coverity.)
3395
3396When resizing a file containing a filesystem, resize2fs will expand or
3397truncate a file as necessary.  (Addresses Debian Bug: #271607)
3398
3399Resize2fs will now automatically determine the RAID stride parameter that
3400had been used to create the filesystem, and use that for newly created
3401block groups.   The RAID stride parameter may also be manually specified
3402on the command line using the new -S option to resize2fs.
3403
3404Fix mke2fs so that it correctly creates external journals on
3405big-endian machines (such as a S/390).  
3406
3407Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3408fail to print out the journal or hash seed UUID.  (Thanks to Guillaume
3409Chambraud for pointing this out.)
3410
3411Dumpe2fs will now print the size of the journal (if present).
3412
3413Fix debugfs's set_inode_field command so it can properly set the frag,
3414fsize, uid_high, gid_high, and author fields in the inode instead of
3415silently failing, and so that setting the i_size actually sets i_size
3416correctly.
3417
3418Add a new debugfs command, set_current_time, which sets fs->now so
3419that regression test suites can repeatedly modify the filesystem's
3420last_write fields.
3421
3422Fix a bug in debugfs's icheck which would incorrectly report the owner
3423of an extended attribute block.
3424
3425Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
3426print a usage message when an illegal option character is given.
3427
3428Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3429so it won't core dump.  (Addresses SourceForge bug #1424311)
3430
3431Fix mklost+found so that it creates a full-sized directory on
3432filesystems with larger block sizes.
3433
3434Fix a file descriptor leak in blkid library.
3435
3436Fix a display bug in "badblocks -sv" so that the done message properly
3437clears the block number at the end of the test.  (Addresses Debian Bug
3438#322231)
3439
3440Allow fractional percentages to the -m option in mke2fs and tune2fs
3441(Addresses Debian Bug: #80205)
3442
3443Use fstat/fstat64 in getsize.c if the the target is a regular file,
3444instead of attempting to do a binary search.  Fix some fd leaks in
3445error cases.
3446
3447Add support for device mapper library to the blkid library to ensure
3448that the "best" (i.e., leaf) device is probed by the blkid library.
3449
3450Fix the blkid library so that it notices when an ext2 filesystem is
3451upgraded to ext3.
3452
3453Improve the blkid's library VFAT/FAT detection; it now understands
3454labels stored in the root directory, and is more paranoid about
3455checking the FAT superblock values.
3456
3457Fixed a fd leak in the uuid library which was causing problems for the
3458LVM tools.  (Addresses Debian Bug: #345832)
3459
3460Add support for the reiser4 and software suspend partitions to the
3461blkid library.  Also add support for extract the label from iso9660
3462filesystems.
3463
3464Fix a compile_et bug which miscount the number of error messages if
3465continuations are used in the .et file.
3466
3467Add extra sanity checks to protect users from unusual cirucmstances
3468where /etc/mtab may not be sane, by checking to see if the device is
3469reported busy (works on Linux 2.6) kernels.  (Addresses Debian Bug
3470#319002)
3471
3472Updated French, Dutch, Polish, and Swedish translations.  (Addresses Debian
3473Bug: #343149, #341911, #300871, #316604, #316782, #330789)
3474
3475Fix use-after-free bug in e2fsck when finishing up the use of the
3476e2fsck context structure.
3477
3478Fixed spelling mistakes, typos, and otherwise clarified man pages and
3479documentation.  (Addresses Debian Bugs: #329859, #322188, #316811,
3480#312515, #351268, #357951, #347295, #316040, #368392, #368393, #368394,
3481#368179)
3482
3483Fixed various Debian packaging issues --- see debian/changelog for
3484details.  (Addresses Debian Bugs #317862, #320389, #290429, #310950,
3485#310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516,

3487
3488
3489Programmer's notes:
3490-------------------
3491
3492Update config.guess and config.sub to latest version (2006-02-23) from
3493FSF.
3494
3495Fix asm_types.h type conflicts on AMD 64 platforms.  (Addresses Debian
3496Bugs: #360661, #360317)
3497
3498Fixed the Makefile so that they work correctly on newer versions of
3499GNU make (i.e., 3.81).
3500
3501Add valgrind support to the regression test suites, and eliminate
3502false positives from valgrind.
3503
3504Add a regression test suite for the blkid library.
3505
3506Fix a fencepost error in resize2fs caught by valgrind.  
3507
3508Fix compiler warnings about missing memcpy prototypes.
3509
3510We no longer have the sparc assembly code in the header file any more,
3511so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc.  This would
3512break compiles on the sparc architectures when using gcc.
3513
3514In the libext2fs library, add the new field fs->now which if non-zero
3515is used instead of the system time when setting various filesystem
3516fields (last modified time, last write time, etc.)
3517
3518Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3519ext2fs.h which is needed since the inline functions use memcpy().
3520(Addresses Sourceforge Bug #1251062)
3521
3522Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3523the build system when building files in the util directory which are
3524needed during the build process.  This avoids potential problems when
3525cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3526are not recognized as valid by the host compiler.  (Addresses
3527Sourceforge Bug #1261547)
3528
3529Clean up the blkid library by making the superblock and generic i/o
3530functions to be more generic.  Clean up interface to the probe
3531function, and fix memory leak.  Finallly, remove an unneeded reference
3532to probe.h in the lib/blkid/resolve.c
3533
3534Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3535of invalid block #'s.
3536
3537The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3538indicate that the the function read/writes the memory location.
3539
3540Fix various gcc -Wall complaints.
3541
3542Add a dependency to make sure that the subdirectories are created
3543before creating all of the object files, in order to address parallel
3544build problem in the library Makefiles.  (Addresses Sourceforge Bug:
3545#1261553)
3546
3547Add $(LDFLAGS) to the command line argument when generating an ELF or
3548Solaris shared library, to allow cross-compile and other builds that
3549might need to specify -L paths to needed libraries.  (Addresses
3550Sourceforge Bug #1261549)
3551
3552Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3553intended for testing purposes.  It allows an ext2/ext3 developer to
3554create very large filesystems using sparse files where most of the
3555block groups are not initialized and so do not require much disk
3556space.  Eventually it could be used as a way of speeding up mke2fs and
3557e2fsck for large filesystem, but that would be best done by adding an
3558RO_COMPAT extension to the filesystem to allow the inode table to be
3559lazily initialized on a per-block basis, instead of being entirely
3560initialized or entirely unused on a per-blockgroup basis.
3561
3562Fix backwards compatibility so e2fsprogs will better compile on Linux
35632.0.35 systems.
3564
3565Make test scripts more robust against locale-related environment variables
3566
3567Fix type warning problem with sizeof() in ext2fs_open2().
3568
3569Fix type warning problem with time_t in debugfs.
3570
3571
3572E2fsprogs 1.38 (June 30, 2005)
3573==============================
3574
3575Fix blkid's test programs (built with "make check") compile correctly
3576even without "configure --enable-blkid-debug".
3577
3578Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3579type aliasing rules on newer gcc compilers.  (Addresses Red Hat
3580Bugzilla ##161183.)
3581
3582Fix com_err library to make it more compatible with recent changes
3583made to the com_err library in MIT Kerberos V5 version 1.4.
3584(Addresses Sourcefroge Bug #1150146)
3585
3586General cleanup of messages printed by e2fsprogs programs for grammar,
3587consistency, and to make life easier for translators.  Fixed a few
3588strings containing English that had not been marked as needing
3589translations.  Removed strings that do not need to be translated, to
3590make life easier for translators.
3591
3592Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3593test to see if a device appears to be in use instead of just relying
3594on /proc/mounts and /etc/mtab.  (Addresses Debian Bug #308594).
3595
3596Fix portability problem in the filefrag program affecting platforms
3597where the size of an integer is smaller than the size of a long.
3598(Addresses Debian Bug #309655)
3599
3600Mke2fs will now use a larger journal by default for filesystems
3601greater than 4GB.  (128 MB instead of 32MB).
3602
3603Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3604unless forced.  This is to avoid signed vs. unsigned kernel bugs in
3605block numbers that still need to be fixed.
3606
3607The blkid program has a new option which will more efficiently search
3608for device when it is known (or expected) that only one matching
3609device will be found in the system, such as when doing a lookup by
3610UUID.
3611
3612Debian's e2fsprogs-specific initrd fragment will avoid including
3613unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3614and LD_LIBRARY_PATH, and filtering out libraries found in
3615/etc/ld.so.preload.  (Addresses Debian Bug: #304003)
3616
3617Fixed a potential portability issue in the blkid programs for
3618architectures where the char type is unsigned.  (Addresses Sourceforge
3619Bug: #1180585)
3620
3621Fix a bug in filefrag so that it doesn't falsely count an extra
3622discontinuity when the first block found is an indirect block.
3623(Addresses Debian Bug #307607).
3624
3625Fix blkid's recognition of cramfs filesystems, and enhance it to be
3626able to handle cramfs labels.
3627
3628Fix debugfs's stat command to not core dump when a filesystem is not
3629open.
3630
3631Fix e2fsck's handling of error conditions caused by the resize inode
3632claiming blocks that are also used by other inodes, a filesystem
3633corruption which was commonly caused by a bug in Fedora Core 3's
3634resize2fs program.
3635
3636Fixed bug in filefrag which caused it to fail on non-ext2/3
3637filesystems.  (Addresses Debian Bug: #303509)
3638
3639If the superblock last mount time indicates that the system clock may
3640not be accurate, then e2fsck will omit checking inodes' deletion time
3641field for indications of a potential corrupted orphaned inode list.
3642(Previously e2fsck only ommited these LOW_DTIME checks when the
3643superblock's last write time looked insane.)
3644
3645Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
3646(Addresses Debian bug #302200)
3647
3648Make the blkid library more paranoid about being run from setgid
3649programs, and to use __secure_getenv() from libc if it is available.
3650
3651Fixed spelling mistakes, typos, and otherwise clarified man pages.
3652(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
3653and Sourceforge Bug: #1189803)
3654
3655Updated and fixed translations.
3656
3657Fixed various Debian packaging issues --- see debian/changelog for
3658details.
3659
3660Programmer's notes:
3661-------------------
3662
3663Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3664changed to take an unsigned int for the bit number.  Negative bit
3665numbers were never allowed (and didn't make any sense), so this should
3666be a safe change.  This is needed to allow safe use of block numbers
3667greater than or equal to 2**31.
3668
3669The compile_et program will avoid recreating generated foo_err.c and
3670foo_err.h files if no changes are necessary.  The compile_et program
3671will also atomically replace these files to avoid a potential parallel
3672build race problem on SMP systems.  (Addresses Sourceforge Bug:
3673#1157933)
3674
3675Added a new function to the blkid library, blkid_probe_all_new(),
3676which only probes newly added disk devices, and change
3677blkid_find_dev_with_tag() to use this function so that when a
3678requested tag is not found, devices that were previously not checked
3679are searched before searching all devices in the system.
3680
3681Added new functions to the blkid library, blkid_dev_set_search() and
3682blkid_dev_has_tag().
3683
3684E2fsck's problem strings can now use @m and @n as abbrevations for
3685"multiply-claimed" and "invalid", respectively.
3686
3687The e2fsprog.pot file now has an explanation of how the @-expansion
3688and %-expansion works, and strings in e2fsck/problem.c which contain @
3689characters now have comments in e2fsprogs.pot with the @-expansion to
3690make life easier for translators.
3691
3692Fixed missing return values in the ext2fs library which could cause it
3693to return random garbage in certain error conditions.
3694
3695Allow the current time to be overriden via the E2FSCK_TIME environment
3696variable for use in regression tests.
3697
3698The test scrpit driver program now exits with a non-zero status if
3699there any of its test that it ran failed.
3700
3701Fixed problems with parabuilds on SMP systems.  (Addresses Sourceforge
3702Bug: #1157933)
3703
3704Fixed "make check" so that it compiles correctly even when e2fsprogs'
3705header files have not be installed in the system include directories.
3706(Addresses Sourceforge Bug: #1180572)
3707
3708Fixed gcc -Wall nits.
3709
3710
3711E2fsprogs 1.37 (March 21, 2005)
3712===============================
3713
3714Add support for checking the validity of Extended Attributes stored in
3715inodes to e2fsck.
3716
3717Add support for dumping the contents of large inodes to debugfs,
3718including the extended attributes stored in inodes.
3719
3720Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3721when we create a new inode we make sure that the extra information in
3722the inode (any extra fields in a large inode and any ea-in-inode
3723information) is initialized correctly.  This can take place when
3724mke2fs creates the root and lost+found directory, when e2fsck creates
3725a new root inode or a new lost+found directory, and when the user uses
3726the debugfs write, mknod, or mkdir commands.  Otherwise, the newly
3727create inode could inherit garbage (or old EA information) from a
3728previously deleted inode.
3729
3730Fixed a bug in e2fsck so it would notice if a file with an extended
3731attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3732to zero.
3733
3734Added support to filefrag to detect files which are using the new
3735experimental file extents format, and use the non-ext2 algorithm in
3736that case.  Fixed a bug to avoid reporting a false discontinuity if
3737there is one or more unallocated blocks at the beginning of a file.
3738
3739Duplicated a check for noticing whether or not the number of blocks
3740(given a certain blocksize) is greater than 2**32 when the
3741BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size().  This
3742allows mke2fs to automatically use a larger blocksize when creating a
3743filesystem on a very large device when run on systems that do not
3744support BLKGETSIZE64.
3745
3746Fix the I18N build which was broken in e2fsprogs 1.36 because the
3747build system had been switched to treat the .gmo files as shipped
3748files (for backwards compatibility with systems that have older GNU
3749I18N tools installed), but the gen_tarball.in script was still
3750removing the .gmo files from the official source distribution.
3751
3752Fixed various Debian packaging issues --- see debian/changelog for
3753details.  (Addresses Debian Bugs ##296769, #299341)
3754
3755Programmer's notes:
3756-------------------
3757
3758Added new functions to the e2p library which convert between a string
3759and os_type: e2p_os2string() and e2p_string2os(), and used them to
3760make the generated binaries more compact.
3761
3762Fixed a compile-time error on Darwin systems.
3763
3764Cleaned up the lib/ext2fs Makefile slightly.
3765
3766
3767E2fsprogs 1.36 (February 4, 2005)
3768=================================
3769
3770All of the patches that were applied to Fedore Core 3's
3771e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3772lot of bug fixes first.  Users of Fedora Core 3 are strongly
3773encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3774
3775Add support for filesystem with the online resizing via resize inode
3776feature.  Fixed numerous bugs from the Fedora patches.  The Fedora
3777patches also didn't bother to do any consistency checking on the
3778resize inode, or add any tests to the regression test suite.  The "-R
3779resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3780being listed in mke2fs's usage message.  All of these shortcomings
3781have been corrected.
3782
3783E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3784program.  In order to do this, the user must run the commands:
3785
3786	debugfs -w /dev/hdXXX -R "features ^resize_inode"
3787        e2fsck -f /dev/hdXXX
3788
3789Optionally, the ext2prepare command can be used to re-enable online
3790resizing after the filesystem has been fixed.
3791
3792The fsck program will now accept an optional filedescriptor argument
3793to the -C option.  (The Fedora version of this patch would sometimes
3794cause fsck to ignore a parameter on fsck's command line in some rare
3795cases, sigh.)
3796
3797Make sure e2fsprogs doesn't write garbage into the reserved portion of
3798large inodes.
3799
3800Make sure resize2fs releases the blocks belonging to the old inode
3801table blocks when moving the inode table.  (Addresses Debian Bug:
3802#290894)
3803
3804Skip the r_resize_inode test if resize2fs is not compiled (due to
3805configure --disable-resizer)
3806
3807E2fsck now checks the summary filesystem accounting information, and
3808if any of the information is obviously wrong, it will force a full
3809filesystem check.  (Addresses Debian Bug #291571)
3810
3811Fix e2fsck to not complain when the resize_inode feature is enabled,
3812s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3813the resize inode.
3814
3815Fix e2fsck to note delete symlinks that contain an extended attribute
3816after the ext_attr feature flag has been cleared.  (Addresses Red Hat
3817Bugzilla #146284).
3818
3819Add new utility program, copy_sparse.c, which is very useful
3820for dealing with large sparse files (such as e2image files).
3821
3822Add support for jnl_blocks[] for debugfs's set_super_value.
3823
3824Fix filefrag so that it works correctly with sparse files.
3825
3826Filefrag -v will print first and last blocks.
3827
3828Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3829and dumpe2fs.
3830
3831Add mke2fs support so that it can support filesystems larger than 4TB
3832automatically, by retrying with a 4k blocksize if the device size is
3833too big to be expressed using a 1k blocksize.  (Addresses Sourceforge
3834bug #1106631)
3835
3836Change blkid to test for NTFS first because Windows sometimes doesn't
3837clear enough of the parition to confuse the probing routines into
3838thinking the old filesystem type is still valid.  (Addresses Debian
3839Bug #291990)
3840
3841Add support for swap partition label and uuid's in the blkid library.
3842
3843Add support to the blkid library to recognize Oracle ASM volumes.
3844
3845Make blkid -t display all devices that match the specified criteria,
3846not just the first one, and work more consistently when the blkid
3847cache file is not available or set to /dev/null.  (Addresses Debian
3848Bug #290530 and #292425)
3849
3850Badblocks will now correctly display block numbers greater than
3851999,999,999 in its progress display.
3852
3853The tune2fs program will not allow the user from setting a ridiculous
3854number of reserved blocks which would cause e2fsck to assume the
3855superblock was corrupt.  E2fsck's standards for what is a ridiculous
3856number of reserved block has also been relaxed to 50% of the blocks in
3857the filesystem.
3858
3859The blkid library will return vfat in preference to msdos, and ext3 in
3860preference to ext2 (if the journalling flag is set) so that mount will
3861do the right thing.  (Addresses Debian bug #287455)
3862  
3863Mke2fs will now use the -E option for extended options; the old -R
3864(raid options) option is still accepted for backwards compatibility.
3865Fix a double-free problem in resize2fs.  (Red Hat Bugzilla #132707)
3866
3867Mke2fs will now accept a size in megabytes, gigabytes, and other units
3868(via "32m" or "4g" on the command line) if the user finds this more
3869convenient than specifying a block count.
3870
3871Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3872cache conherency problem.
3873
3874Debugfs now supports a new command, set_inode_field, which allows a
3875user to manually set a specific inode field more conveniently, as well
3876as set entries in the indirect block map.
3877
3878Debugfs's set_super_value command has been enhanced so that the user
3879can set most superblock fields, including the date/time fields and
3880some of the more newsly added superblock fields.
3881
3882E2fsprogs programs now accept an offset to be passed to the file
3883specifiers, via the syntax: "/tmp/test.img?offset=1024".
3884
3885E2fsprogs programs will now accept blocksizes up to 65536; kernel
3886support on the x86 doesn't exist for now, but it can be useful on
3887other architectures with page sizes greater than 4k.  There are 2.6
3888kernel patches out there which enable this, but they are of this
3889writing still experimental.
3890
3891The e2image command now takes the -s option which will scramble
3892directory entries for raw image files.
3893
3894Fix a file descriptor leak in the filefrag program.
3895
3896Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3897present.
3898
3899Fix bug in debugfs where kill_file would lead to errors when deleting
3900devices and symlinks.  (Sourceforge Bugs #954741 and #957244)
3901
3902Fix bug in the blkid library when detecting the ocfs1 filesystem 
3903
3904Remove obsolete EVMS 1.x and a.out DLL support.
3905
3906E2fsck will attempt to recover from a journal containing illegal blocks.
3907
3908Fixed two potential ordering constraint problems in e2fsck which might
3909cause the filesystem to be corrupted if e2fsck is interrupted during a
3910(extremely narrow) race window.  Thanks to Junfeng Yang from the
3911Stanford Metacompilation group for pointing this out.
3912
3913Fixed bug in e2fsck where it would not accurately detect whether or
3914not the system is running on adaptor if the ACPI device representing
3915the AC adapter didn't correspond to the what was used on IBM
3916Thinkpads.
3917
3918Change e2fsck to accept directories greater than 32MB.
3919
3920Fix e2fsck so that a checkinterval of zero disables a time-based check
3921of the filesystem.
3922
3923Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3924to the PAGER environment variable.  (Addresses Debian Bug #239547)
3925
3926Tune2fs will not mark rewrite the superblock if the feature bitmasks 
3927are not modified.
3928
3929The debugfs program will set the filetype information when creating a
3930link.
3931
3932Add debugfs -d option to use a separate source of data blocks when
3933reading from an e2image file.
3934
3935Add e2image -I option which allows the e2image metadata to be
3936installed into a filesystem.
3937
3938Fixed bug in the badblocks program which caused "done" to always
3939appear in english even when a translation was available.  (Addresses
3940Debian Bug #252836)
3941
3942The blkid program has a new option -o which controls the output format
3943of the blkid program; this is makes blkid more convenient to use in
3944shell scripts.
3945
3946Fix a minor bug in uuid library, which was not using the full 14 bits
3947of clock sequence when generating UUID's.
3948
3949Fix a Y8.8888K problem in the uuid library.
3950
3951Logsave now creates a new session id for itself to avoid getting
3952killed by init whan transitioning between init levels.
3953
3954Change the licensing of the UUID library to be the 3-clause BSD-style
3955license; this allows Apple to use the uuid library in Darwin.
3956
3957Add ocfs and ocfs2 probe support into the blkid library.
3958
3959Fix a memory and file descriptor leak in the blkid library.
3960
3961The blkid library will revalidate the device if the system time is
3962earlier than last verification time of the device, since that
3963indicates that the system time is probably nottrustworthy.
3964
3965The blkid library will override the default location of the blkid.tab
3966file by the BLKID_FILE environment variable, if it is available.
3967
3968Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3969
3970Add various portability fixes for lame new versions of glibc, Darwin
3971and GNU/KFreeBSD, as well as removing XSI:ism's.  (Addresses Debian
3972Bugs #239934, #264630, #269044, #255589, #289133)
3973
3974Add support for Windows 9x/NT under Cygwin.
3975
3976Updated and clarified various man pages.  (Addresses Debian Bugs #236383,
3977	#241940, #238741, #242995, #256669, #268148, #256760, #273679)
3978
3979Updated and fixed translations.   (Addresses Debian bugs #244105, #262836)
3980
3981Update the rpm spec files so that it works better with Fedora core 2
3982and RH9.
3983
3984Fixed various Debian packaging issues (see debian/changelog).  In
3985particular, fixed the Debian initrd scripts.  (#241183, #248050,
3986#253595, #247775)
3987
3988
3989Programmer's notes: 
3990-------------------
3991
3992Fixed various gcc -Wall warnings.
3993
3994The uuid library now has new functions uuid_unparse_upper() and
3995uuid_unparse_lower() which forces the case of the hex digits to be
3996upper case, or lower case.
3997
3998The build process has been speeded up by enhancing the subst program
3999to update the modtime on the generated files even when the generated
4000file hasn't changed.
4001
4002The uuid library now uses C99 stdint.h types instead of custom types.
4003
4004Updated config.guess and config.sub with newer versions from the FSF.
4005
4006Removed out of date .cvsignore files from the source distribution.
4007
4008The ext2fs_unlink() function will return an error if both the name and
4009inode number are unspecified, to avoid doing something surprising
4010(such as unconditionally deleting the first directory entry).
4011Directory entries are now deleted by coalescing them with the previous
4012directory entry if possible, to avoid directory fragmentation.  This
4013is not an issue with the e2fsprogs suite, but may be a problem for
4014some of the users of libext2fs, such as e2tools.
4015
4016Add support for version numbers of the form "1.36-rc1".
4017
4018Fix build of mke2fs.static.
4019
4020Add basic ext2fs library support for large (EA in inode) inodes.
4021
4022The test_io mechanism can now abort after n reads or writes to a
4023particular block.  The block is specified by TEST_IO_BLOCK environment
4024variable, and the read/write count by the TEST_IO_READ_ABORT and
4025TEST_IO_WRITE_ABORT environment variables.  The block data is now only
4026dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4027
4028UUID_DEFINE() in the uuid library now creates a static variable, with
4029__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4030be used in header files.
4031
4032Add support for the install-strip and install-shlibs-strip targets, as
4033suggested by the GNU coding guielines.  "make install" no longer
4034strips the binaries which are installed.
4035
4036Remove support for the --enable-old-bitops configure option which was
4037only for very old sparc systems.
4038
4039Remove support for --enable-clear-htree; this was only needed during
4040the early development of the htree patch.
4041
4042Use Linux-kernel-style makefile output so it is easier to see compiler
4043warnings.
4044
4045Update gettext files to version 0.14.1.
4046
4047Update to use autoconf 2.5x.
4048
4049Improved support for compiling e2fsprogs under dietlibc.
4050
4051Make e2fsprogs portable to Solaris and FreeBSD systems.
4052
4053Add blkid_verify(), blkid_get_library_version(), and
4054blkid_parse_version_string() functions to the blkid library.
4055
4056Add pkg-config files for e2fsprogs's libraries.
4057
4058Fix "make uninstall" to so that it removes everything that is installed.
4059
4060Add a configure --enable-maintainer-mode option which enables the
4061makefile rules to rebuild the configure script from configure.in, and
4062to reubuild the .gmo files in po directory.
4063
4064Drop the sparc assembly bitwise operations; it's less efficient
4065than the GCC 3.4 compile code and triggers compiler warnings on
4066sparc64.  Thanks to Matthias Andree for his analysis and suggestions.
4067(Addresses Debian Bug #232326)
4068
4069
4070E2fsprogs 1.35 (February 28, 2004) 
4071==================================
4072
4073E2fsck has a new -k option, which in conjunction with the -c options,
4074preserves the existing badblocks list.
4075
4076Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
4077
4078E2fsprogs will now deal correctly with symlinks that contain
4079extended attribute information, which can be created using SE Linux.
4080(Addresses Debian Bug #232328)
4081                                                                               
4082Remove a double longjump into an invalid stack frame bug in e2fsck.
4083(This was during an abort sequence, which normally worked on Linux and
4084caused a core dump on other operating systems.)
4085
4086Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
4087(the NLS library will replace "" with the .po header information).
4088 
4089Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4090dump due to a division by zero error.  (Addresses Debian bug #207082)
4091
4092Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4093when reconnecting a directory requires creating a lost+found
4094directory.  (Addresses Debian bug #219640).
4095
4096Fixed a bug where e2fsck would bomb out if a journal needed to be
4097replayed when using an alternate superblock.
4098 
4099E2fsck will give an extra grace period before actually forcing a check
4100if the laptop is running on battery.  The next time fsck runs while
4101the system is on the AC mains, or after the grace period is exceeded,
4102the filesystem will be checked.  (Addresses Debian bug #205177)
4103
4104E2fsck will inform the user when there are 5 or fewer mounts before a
4105filesystem check will be forced.  (Addresses Debian bug #157194)
4106
4107Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4108We now correctly handle the case where there is an overlap between a
4109block group descriptor or a superblock and a bad block indirect block.
4110In the case where the indirect block is corrupted, we now suggest
4111"e2fsck -c".
4112
4113Fix byte swap bugs in e2fsck that caused the journal backup location 
4114in the superblock and symlinks created by SE Linux to be cleared
4115by e2fsck on big-endian machines.  (Addresses Debian bug #228723)
4116
4117E2fsck -c now replaces the current list of bad blocks with the ones
4118found by badblocks.
4119
4120Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4121non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4122
4123Fix a potential bug in e2fsck which could cause it to core dump when
4124trying to print the location of the backup superblock.
4125
4126Protect against a potential core dump in e2fsck when printing a
4127message about backup superblocks.
4128
4129Add support for backing up the journal inode location in the
4130superblock.  E2fsck will automatically save the journal information in
4131the superblock if it is not there already, and will use it if the
4132journal inode appears to be corrupted.  ext2fs_add_journal_inode()
4133will also save the backup information, so that new filesystems created
4134by mke2fs and filesystems that have journals added via tune2fs will
4135also have journal location written to the superblock as well.
4136Debugfs's logdump command has been enhanced so that it can use the
4137journal information in the superblock.
4138
4139E2fsck will now update all superblocks when moving the journal inode.
4140  
4141Shrink the size of the e2fsck executable by moving some initialized
4142variables to the BSS segment.
4143
4144E2fsck will avoid printing the ^A and ^B characters which bracket the
4145progress bar when stdout and stdin are a tty device instead of a pipe
4146to another program.  (Addresses Debian bug #204137)
4147
4148Debugfs's mkdir command will automatically expand the directory if
4149necessary.  (Addresses Debian Bug: #217892)
4150 
4151Fixed a bug in debugfs so that copying a file from /dev/null uses the
4152correct mode bits.  (Addresses Debian Bug: #217456)
4153 
4154If the environment variables DEBUFS_PAGER and PAGER are not set,
4155debugfs now searches for the appropriate pager to use, beginning with
4156/usr/bin/pager, and then falling back to 'more' and 'less'.
4157(Addresses Debian bug #221977)
4158
4159Debugfs will now support 2.6 device numbers where the major or minor
4160number may be larger than 255.  (Addresses Sourceforge bug #865289)
4161 
4162Fix debugging printf in resize2fs.  (Addresses Debian Bug #271605)
4163
4164Chattr now stops processing options when it sees '--'.  (Addresses
4165Debian bug #225188)
4166
4167Fix regression tests so they work correctly when e2fsprogs is compiled
4168with configure --disable-htree.
4169
4170Fix bug in uuid library when there is no network card and the library
4171is generating a time-based uuid.  The random MAC address was not
4172correctly generated to be a multicast address.
4173 
4174Add compile_et extensions from Heimdall that were missed the first time
4175around.
4176
4177Fix bug in badblocks when using O_DIRECT; we need to make sure that
4178we're reading from an offset which is page aligned.  For read-only and
4179read-write tests, we try to recover after an error so that we can
4180continue reading on page-aligned boundaries.  (Addresses Debian Bug
4181#203713)
4182  
4183Badblocks now checks 64 blocks at a time instead of 16.  (Addresses
4184Debian bug #232240)
4185 
4186Updated and clarified various man pages.  (Addresses Debian Bug
4187#206845, #222606, #214920, #232406)
4188
4189Updated and fixed translations.   (Addresses Debian bugs #200086, #214633)
4190
4191Fixed various Debian packaging issues (see debian/changelog).
4192
4193Programmer's notes: 
4194-------------------
4195
4196Fixed a build problem so that e2fsprogs would compile with the
4197--enable-profile option to configure selected.  (Addresses Sourceforge
4198bug #811408)
4199 
4200Fixed C++ problems with the ext2fs.h header.  (Addresses Red Hat
4201Bugzilla Bug #112448)
4202                                                                               
4203Centralize code which calculates the location of the superblock
4204and block group descriptors so that it is in a single library routine.
4205
4206Added two new functions, ext2fs_file_open2() and
4207ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4208
4209Fix compile_et to output the correct prototype for
4210initialize_xxx_err_table_r() in the header file.  (Addresses Debian
4211bug #204332)
4212
4213In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4214  
4215Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4216present.  This is for when we try stuffing an int into void * pointer.
4217
4218Fix type-punning which can cause gcc 3.x to miscompile code by getting
4219confused about pointer aliasing.  ext2fs_getmem(), ext2fs_free_mem(),
4220and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4221**'.  The EVMS code uses an ugly union approach since we don't want to
4222modify the EVMS interfaces. 
4223
4224Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4225aid build process on systems can use invoke GNU make as "gmake".
4226
4227Added regression testing for mke2fs.
4228
4229Fixed gcc -Wall nitpicks.
4230
4231Fixed various compiler warnings.
4232
4233Add portability fixes for FreeBSD and for using fsctl under Darwin to
4234support ext2 ioctl's.
4235
4236
4237E2fsprogs 1.34 (July 25, 2003)
4238===============================
4239
4240Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4241a tight loop while waiting for a child fsck to exit in some cases.
4242This burns CPU times which slows down the low-level filesystem check.
4243
4244Added code to mke2fs to assure that the default block size for a
4245filesystem is at least as big as the sector size of the device, if it
4246can be determined.
4247
4248Changed mke2fs and resize2fs to round the default size of a filesystem
4249to be an even multiple of the VM pagesize in order to avoid a Linux
4250kernel bug introduced when the storage of the buffer cache was moved
4251into the page cache.
4252
4253Mke2fs will warn the user when creating a filesystem with journaling
4254and a blocksize greater than 4096.  (Addresses Debian bug #193773)
4255
4256Fixed a bug in resize2fs which caused it to fail on filesystems with a
4257non-empty bad block list.  Resize2fs now discards any blocks on the
4258badblock list which are no longer part of the filesystem as the result
4259of a filesystem shrink.  (Note: this means that shrinking and then
4260enlarging a filesystem is no longer a reversible operation;
4261information about bad blocks in the part of the filesystem which is to
4262be chopped off will be lost.)
4263
4264Changed resize2fs so the user can use prefixes to specify the units of
4265the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4266and to make the error and informational messages explicitly display
4267the blocksize used by the filesystem, in order to avoid confusion.
4268(Addresses Debian bug: #189814)
4269
4270Added a new debugfs command, dump_unused, which dumps the contents of
4271all unused blocks to stdout.  (Useful as an emergency try-to-find
4272deleted data command.)
4273
4274Added a new debugfs command, imap, which prints the location of a
4275specified inode in the inode table.
4276
4277Fixed a bug in the badblocks program which caused it to use one bit of
4278randomness in its non-destructive read/write test, instead of using a
4279full 8 bits of randomness.
4280
4281Added a new option (-t) to badblocks, which allows the user to control
4282the test pattern(s) used when checking a disk.
4283
4284The blkid probe function now more correctly detects UDF filesystems.
4285
4286Fixed a bug in the blkid library which caused it to not update its
4287cache if a filesystem changes from having a label to not having a
4288label.
4289
4290Fixed a bug in the blkid library wihch could avoid an infinite loop
4291in blkid_find_dev_with_tag() if /proc is not mounted and there the
4292/etc/blkid.tab file has not yet been created.
4293
4294Fixed the badblocks program so that the destructive read/write test
4295honors the -c option, and to use O_DIRECT when possible to avoid
4296thrashing the system block buffer cache.
4297
4298Fixed various NLS issues.
4299 - Added Czech and Swedish translations
4300 - Removed testing NYC translation
4301 - Fixed NLS support for message abbrevations in e2fsck
4302 - Remove de-utf.po, since we shouldn't have two versions using different
4303	charset encodings.
4304 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 
4305	simplify the statistics reporting in e2fsck.
4306
4307Changed configure.in so that its defaults for *BSD systems no longer
4308build an fsck wrapper, and not to install in /usr/local by default.
4309
4310Fixed some minor spelling errors/typo's in e2fsck and the configure
4311script.
4312
4313Fixed various Debian packaging issues (see debian/changelog). 
4314
4315Updated and clarified man pages.  (Addresses Debian Bug #195616)
4316
4317Programmer's notes: 
4318-------------------
4319
4320Fix gcc -Wall nitpicks.
4321
4322Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4323NLS support by default.  (Added partial workaround for gettext/Darwin
4324incompatibility problems.)
4325
4326Added full MIT KRB5 and Himdall compaibility support to the com_err
4327library and the compile_et program.  (Addresses Debian bug #191900)
4328
4329Added the blkid_known_fstype() function to the blkid library, which
4330returns true if it is passed a filesystem type which is recognized by
4331the blkid probing functions.
4332
4333Improved the documentation for the blkid library.
4334
4335Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4336returns the hardware sector size of a device, if it is available.
4337
4338Added a dependency in the blkid library's .so file to the uuid
4339library, since the former uses the latter.  (Addresses Debian bug
4340#194094)
4341
4342Added --with-diet-libc and --disable-evms to the configure script.
4343
4344Fixed a minor memory leak in the badblocks program.
4345
4346Fixed a portability problem in tune2fs --- not all systems have strptime().
4347
4348Fixed a portability problem in debugfs with the use of getopt() more
4349than once.  Old-style BSD, new-style BSD, and Linux C libraries all do
4350things differently.
4351
4352Add support Windows support to ext2fs_get_device_size().
4353
4354Added (normally disabled) debugging code to the Unix I/O manager which
4355causes it to disable all userspace caching if the NO_IO_CACHE is
4356defined.
4357
4358Changed the test I/O manager so it can always be linked into e2fsck,
4359mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4360configure script.  The test I/O manager will only print any debugging
4361information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4362variables are set, which specifies which I/O operations are logged and
4363a block number to watch, respectively.  The log messages are sent to
4364stderr by default, unless a filename is specified via the
4365TEST_IO_LOGFILE environment variable.
4366
4367
4368E2fsprogs 1.33 (April 21, 2003)
4369===============================
4370
4371Added a new utility program, logsave, which captures the output of a
4372command in a log file, even if the containing directory hasn't been
4373mounted yet (in which case the it saves the output in memory until it
4374can write out the logfile).  This is useful for capturing the
4375output of fsck during the boot sequence.
4376
4377Fixed some portability problems that were causing problems under
4378the Cygwin32 environment.
4379
4380Mke2fs now interprets a negative number to the -b option as a minimum
4381block size.
4382
4383Fixed a bug in mke2fs which was incorrectly checking the argument to
4384the -g option if the default block size was used.  (Addresses Debian
4385bug #188319)
4386
4387Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4388it can not find filesystem checkers for jfs, reseirfs, and xfs.
4389
4390E2fsck now updates the global free block and inode counters from the
4391block group specific counters quietly.  This is needed for an
4392experimental patch which eliminates locking the entire filesystem when
4393allocating blocks or inodes; if the filesystem is not unmounted
4394cleanly, the global counts may not be accurate.
4395
4396Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree.  (EVMS
43972.0 is not yet supported; this only pulled in the bug fixes: fixed
4398possible hangs caused by bugs in calling waitpid, and not setting the
4399pipe to non-blocking mode; also fixed a file descriptor leak; made
4400sure all functions call log entry/exit functions.)
4401
4402Badblocks now flushes its output file as bad blocks are discovered.
4403
4404The uuid library is now more paranoid about assuming the correctness
4405of the /dev/random device; it mixes in a stream of bytes from
4406random/srandom, just in case.
4407
4408Update Debian files to reflect the fact that I am now the Debian
4409maintainer of e2fsprogs.  Other various Debian-specific packaging
4410cleanups.
4411
4412Move the source tarball generation functions from the top-level
4413makefile to the util/gen-tarball script.  
4414
4415Updated the Turkish .po translation file.
4416
4417Added Heimdal and MIT krb5 extensions to the com_err library to make
4418it more compatible with com_err libraries from those distributions.
4419
4420Changed dumpe2fs to always display the superblock fields relating to
4421the journalling and/or directory indexing feature even if those
4422features are not enabled.
4423
4424Updated and clarify copyright statement vis-a-vis alpha releases of
4425e2fsprogs.
4426
4427The ss library will now try to dynamically link to the readline
4428library and use it if it is present in the system.  This means that
4429the debugfs program now has line editing and history features.  The
4430SS_READLINE_PATH environment variable is used to find a readline or
4431readline-compatible library.
4432
4433E2fsck now finds most duplicate filenames (all when rebuilding all
4434directories via the -D option) and offers to delete or rename
4435duplicate filenames/directory entries.  (Addresses Debian Bug #176814).
4436
4437Fix bug in e2image.  When writing out a raw image file, include data
4438blocks from symlinks that do not store the symlink within the inode.
4439
4440Fix bug in resize2fs which incorrectly moved the block and inode
4441bitmaps for sparse superblock filesystems and incorrectly marked
4442blocks as in use.  (Addresses Debian bug #174766)
4443 
4444Added a new shared library, the blkid library, which efficiently
4445allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4446and UUID filesystem specifiers without needing to search all of the
4447devices in the system.  Instead, the device is looked up in a cache
4448file, and then verified to make sure the blkid cache is correct.
4449
4450Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4451the device name, using the blkid library.  (Addresses Debian bugs
4452#166048, #179671)
4453
4454Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4455used for spaces in device labels.
4456
4457Removed 32-bit limitations for debugfs's dump command.
4458
4459If the user specifies a large number of inodes, Mke2fs will
4460automatically adjust the number of blocks per group to find a valid
4461set of filesystem parameters.
4462
4463Add workaround to detect broken MD devices where when some of the
4464underlying devices are marked read-only, writes to the MD device are
4465silently dropped.  E2fsck will detect if there is an attempt to run
4466the journal twice, and abort with an error if this is the case.
4467(Addresses IBM Bugzilla bug #1226)
4468
4469E2fsck will print an error if more than one of the -p/-a, -n or -y
4470options are specified.
4471
4472E2fsck will fix HTREE corruptions in preen mode, without stopping the
4473boot process.  This is needed because the 2.4 ext2 filesystem
4474accidentally had the INDEX_FL backwards compatibility code removed.
4475
4476Mke2fs no longer creates filesystems with the dir_index flag set by
4477default; the user has to specifically request it.
4478
4479Update and clarified various man pages. (Addresses Debian bugs
4480#173612, #175233, #175113, and #170497, #185945, #188318)
4481
4482Created man page for the mk_cmds program (from the libss library).
4483
4484Programmer's notes: 
4485-------------------
4486
4487Fix various gcc -Wall nits.
4488
4489Fixed a lot of portability problems that caused e2fsprogs not to build
4490successfully under Solaris and Apple/Darwin.
4491
4492Fixed a Makefile dependency to allow building e2fsprogs using parallel
4493make jobs.
4494
4495Changes to create a subset distribution which consists only of the
4496et, ss, uuid, and blkid libraries.  The configure script and top-level
4497makefile were changed to support working with a subset distribution.
4498
4499Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4500actually used, and might people who are looking for
4501EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4502
4503Updated debian files to fix a number of Lintian warnings.
4504
4505Updated config.guess and config.sub with newer versions from the FSF.
4506
4507Removed unnecessary libraries from being linked into the fsck, lsattr, 
4508chattr, and blkid executables.
4509
4510E2fsprogs 1.32 (Nomvember 9, 2002)
4511==================================
4512
4513Fixed a bug in the Unix I/O routines which caused needless writebacks
4514of clean blocks from the unix_io cache (they were erroneously marked
4515as being dirty, so they were getting written back to disk before
4516getting evicted from the disk cache).  This was harmless, but it
4517significantly slowed down e2fsck.
4518
4519Made some other minor optimizations to the Unix I/O routines to save a
4520small amount of CPU time.
4521
4522Updated internationalization files.
4523
4524
4525E2fsprogs 1.31 (Nomvember 8, 2002)
4526==================================
4527
4528Update EVMS ext2fsim plugin with EVMS 1.2.  (We still support
4529compiling the fsim plugin with EVMS 1.0 and 1.1.)  Add better error
4530handling for child process that die unexpectly.  Add a hack to force
4531mkfs to create filesystems that won't cause problems with hardware
4532that has 2k or 4k minimum blocksize requirements.  Read from child
4533processes in non-blocking mode, so that the GUI continues to update.
4534
4535Fix e2fsck so that it returns the appropriate exit code when the root
4536filesystem has been changed, so that system's rc scripts will be told that 
4537the system needs to be rebooted.
4538
4539Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4540was set, some of the descriptor blocks that should have been written
4541out were getting skipped.
4542
4543Changed e2fsck to force out changes to the backup copies of the
4544superblock and block group descriptors when important changes are made
4545to those data structures.
4546
4547Fix a bug where e2fsck could erroneously mark a filesystem as being
4548clean if a check of dirty filesystem is interrupted with a ^C.  (Bug
4549introduced in e2fsprogs 1.28.)
4550
4551If journal debuging is enabled using --enable-jbd-debug, the debugging
4552level is now set via the E2FSCK_JBD_DEBUG environment variable.
4553
4554If byteswapping support is disabled using configure --disable-swapfs,
4555skip the tests which depend on byte-swapping, so that "make check"
4556won't bomb out.
4557
4558Lshattr will now display the indexed directory flag.  Also, some of
4559the more esoteric compression flags are supressed unless compression
4560support has been enabled.
4561
4562Update man pages.
4563
4564
4565E2fsprogs 1.30 (October 31, 2002)
4566=================================
4567
4568When resizing a filesystem, and inodes need to moved, resize2fs will
4569update the inode's ctime field, and the mtime field of the containing
4570directories, so that incremental backups using dump/restore will work
4571correctly.
4572
4573In order to avoid spurious errors, e2fsck wil check the last
4574superblock write time to determine whether or not it can safely use
4575the LOW_DTIME checks to determine if there are inodes on the orphan
4576inode linked list that had somehow gotten disconnected.  (Addresses
4577Sourceforge bug #620980)
4578
4579Partition in /proc/partitions that being with the string "lvm" are
4580considered real partitions even if they do not end with a number.
4581
4582Fixed a bug in the the uuid generation function, where if /dev/urandom
4583is not present, but /dev/random is, and there isn't sufficient
4584entropy, the get_random_byte function could spin a loop forever.
4585
4586E2fsck, mke2fs, etc. will now reliably notice when image files are
4587mounted using the loopback interface.  (Addresses Sourceforge bug
4588#619119)
4589
4590When flushing buffers (as is done by badblocks, for example) check to
4591see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4592FDFLUSH ioctl which causes the MD device driver which causes confusing
4593syslog messages about obselete ioctl messages.  (Addresses Sourceforge
4594bug #545832).
4595
4596Debugfs's write command now checks to see if the destination filename
4597exists before creating it.  (Addresses Sourceforge bug #478195.)
4598
4599When installing man pages, search for compressed man pages using all
4600commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4601
4602Fixed a bug in fsck where multiple filesystems specified on the
4603command were not being checked in parallel due to a logic bug
4604introduced to support the FSCK_MAX_INST environment variable.
4605
4606We have added a new superblock field, s_mkfs_time, which indicates
4607when a filesystem was created.  It is set via mke2fs, and printed out
4608by dumpe2fs, but is not actually touched by the kernel.
4609
4610Dumpe2fs has been made more robust by not aborting if there is an
4611error reading the block/inode bitmaps; instead it will still print out
4612the location of the block/inode bitmaps and inode table.
4613
4614Add support for the an alternative block group descriptor layout which
4615allows for on-line resizing without needing to prepare the filesystem
4616in advance.  (This is the incomat feature flag meta_bg.)
4617
4618Add support for storing default mount options in the superblock, so
4619that the filesystem can be mounted with specific mount options without
4620needing to specify them on the mount command line or in the /etc/fstab
4621file.
4622
4623Add support for a new inode flag, which is to be used for indicating
4624the top of directory hierarchies for the Orlov block allocator.
4625
4626Fix e2fsck so that if it creates the lost+found directory, it does so
4627with the more apporpriate permissions of 0700.  Also change
4628mklost+found so that it also creates the directory 0700.
4629
4630Fixed format bug in e2fsck if NLS is in use.
4631  
4632Add a German translation for e2fsprogs's NLS support.
4633
4634Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4635the beginning of the inode table.  This won't matter much, since if
4636there is a bad block at the beginning of the inode table, the root
4637directory won't be available.  But at least e2fsck won't crash in this
4638case.
4639
4640Fixed endian problems in the htree code for e2fsck and debugfs.
4641  
4642When byte-swapping a filesystem on a PPC architecture, byte-swap the
4643bitmaps since the historical big-endian ext2 variant had byte-swapped
4644bitmaps, and the ext2fs library assumes this.  This fixes the
4645regression test suite on PPC machines.
4646
4647Fix e2image so that it handles a bad block in the inode table
4648appropriately.
4649
4650E2fsck now uses a more sophisticated algorithm to salvage corrupted
4651directories that recovers more information in the corrupted directory
4652block.
4653
4654E2fsck now performs additional consistency checks on indexed (HTREE)
4655directories.
4656
4657Fix bug where efsck might get confused about whether a completely
4658empty directory block is an empty leaf block or an interior htree
4659node.  This could cause e2fsck to get confused into think that a valid
4660indexed directory was corrupted.
4661
4662E2fsck no longer creates an empty directory entry at the end of a
4663directory block when optimizing a directory.  This would cause some
4664earlier versions of the dxdir kernel code to corrupt the directory
4665when attempting to split a node containing an empty directory entry.
4666
4667E2fsck could sometimes in rare circumstances leave the indexed flag
4668set after a small directory was optimized by compressing it instead of
4669indexing it.  (This should never happen in real life, since
4670directories that small wouldn't have been indexed, but better safe
4671than sorry.)
4672
4673E2fsck now only updates the master superblock in all cases.  This
4674slightly shortens its run time.
4675
4676Ext2ed can deal with directory entries of length 0; previously it
4677would get stuck in an infinite loop.
4678
4679Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4680specifiers.  (Sourceforge patch #613447)
4681
4682Badblocks will now work correctly on read-only devices such as
4683CD-ROM's.  (Sourceforge patch #600451)
4684
4685Updated and clarified man pages.  (Addresses Debian bug #167108)
4686
4687
4688E2fsprogs 1.29 (September 24, 2002)
4689===================================
4690
4691Fixed a bug in e2fsck which could corrupt a directory when optimizing
4692it (via the -D option) or rebuiliding the hash tree index with a 1 in
4693512 probability, due to a fence post error.
4694
4695Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4696work correctly.
4697
4698Mke2fs now enables the directory indexing flag by default.  (Since
4699this is a compatible feature flag, it's safe to do so.)
4700
4701Tune2fs will support setting the directory indexing feature flag.  It
4702will automatically set up the default hash algorithm and hash seed
4703fields in the superblock.
4704
4705If the bone-headed user enters the root filesystem twice in
4706/etc/fstab, the -R option which skips the root filesystem will skip
4707all of them.  (Addresses Debian bug #159423).  Note!  This is not a
4708precedent for dealing intelligently with any other kind of doubled
4709entry in /etc/fstab!
4710
4711
4712Programmer's notes: 
4713-------------------
4714
4715Removed perror declaration in lib/et/internal.h.  All modern systems
4716can be expected to define perror() these days.  Besides, the lib/et
4717code wasn't using perror at all anyway.  :-)
4718
4719
4720E2fsprogs 1.28 (August 31, 2002)
4721================================
4722
4723Add support for the Hashed-Tree Directory Indexing to e2fsck.  Support
4724for setting the htree flag is not included yet, although it can be
4725manually turned on via the debugfs program.
4726
4727Clarified e2fsck error message which is printed when it cannot find
4728sufficient contiguous block when relcating filesystem metadata.
4729
4730Added support for building an EVMS plugin module for ext2/3.  This
4731module is substantially the same as the EVMS module shipping with EVMS
47321.1, with one or two bugfixes.  E2fsprogs can also build this plugin
4733for use with EVMS 1.0 (which did not include the ext2 plugin module),
4734if the configure --enable-old-evms flag is given.
4735
4736Fsck will search through EVMS volumes when trying to resolve
4737filesystem specifications such as LABEL=xxx or UUID=xxx.
4738  
4739Added a new utility program, /sbin/findfs, which will return
4740filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4741the device name.
4742
4743Update and clarified various man pages. (addresses Debian Bug #145044,
4744#146437, #131350, #151990, #144621, #141938)
4745
4746If there are no filesystems specified on fsck's command line, fsck now
4747treat that as if the -As options were given.  Previously it would
4748simply do nothing.  (Addresses Debian Bug #153102)
4749
4750Mke2fs no longer treats a failure to be able to clear the MD signature
4751at the end of the filesystem as a fatal error.  (Addresses Debian Bug
4752#155007)
4753
4754The e2p library functions (which are used by lsattr and chattr) now
4755double check to make sure the file is a regular file or directory
4756before attempting to use the ext2 ioctls.  Some device drivers
4757unfortunately respond to the ext2 ioctl's with unknown behaviour.
4758(Addresses Debian Bug #152029).
4759
4760The extended attribute handling has been updated to correspond with
4761the latest V2 bestbits ACL code.
4762
4763Fixed bug in e2fsck which caused it to not clear the dtime field when
4764processing truncated inodes on the orphan list.  This could cause data
4765loss(!) if a filesystem is rebooted before a truncate has been
4766committed.
4767
4768E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4769algorithms.  This makes e2fsck much faster in the case of severely
4770corrupted filesystems where a large number of blocks are claimed by a
4771large number of inodes.  (Thanks to the 2.5 IDE device driver for
4772inspiring this work.)
4773
4774Resize2fs has been significantly sped up when shrinking and expanding
4775a filesystem by a very small number of blocks (for example, when EVMS
4776is converting a partition to be an EVMS legacy volume).
4777
4778Added a new option to e2fsck, -D, which will optimize or compress all
4779of the directories in the filesystem.
4780
4781E2fsck now catches SIGINT and SIGTERM to make sure it will can
4782properly clean up and only exit at safe points.  Fsck will pass
4783SIGINT/SIGTERM to its child processes, and wait until they have all
4784exited before it exits.
4785
4786The uuid parsing code in the uuid library now properly complains when
4787an illegally formated uuid is presented to it.  (Addresses Debian bug
4788#152891)
4789
4790Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4791and 2.4.17, since the workaround can cause problems when using a 2.4
4792kernel with an old version of glibc built with the 2.2 headers.
4793
4794Fixed a bug in mke2fs where it wasn't properly clearing the initial
4795superblock used by other filesystems.  (Addresses Debian bug #147256.)
4796
4797Added support for the synchronous directory feature written by Andrew
4798Morton.
4799
4800The debugfs program can delete directories using the rmdir command.
4801
4802Add support for 8k and 16k filesystems (for systems with page sizes
4803that are greater or equal to 8k or 16k, respectively).  Note that
4804these filesystems can not be mounted on x86 systems, or other systems
4805with only 4k page sizes, due to limitations in the current Linux VM
4806code.
4807
4808Resize2fs requires that the filesystem state be valid and have no
4809errors; otherwise, e2fsck -f must be run first.  (Previously it simply
4810required that the last fsck time be greater than the last mount time.)
4811
4812Configure now defaults the man pages directory to /usr/share/man on
4813Linux systems.
4814
4815E2fsck now offers to truncate inodes which contain too many blocks (so
4816that i_blocks would overflow.  Also fixed handling of large sparse
4817files.
4818
4819E2fsck now more completely checks for symlink validity, including
4820requiring NULL termination and length checks.
4821
4822E2fsck will offer to try forcing a disk write to remap a bad block
4823after finding a read error when reading a filesystem metadata block.
4824
4825Fixed a bug in debugfs which caused the -b and -s options to crash
4826debugfs, as well as breaking the testb, setb, and clearb functions.
4827
4828Added a bmap command to debugfs which calculates the logical to
4829physical block mapping for a particular inode.
4830
4831Fixed a bug in code which checked to see if a device was mounted which
4832sometimes (rarely) failed in the case of a plain file.
4833
4834Fixed a bug in resize2fs where when it reported an error, it would
4835print a message erroneously indicating that the filesystem had been
4836resized before it aborted.
4837
4838When resizing a plain file which is smaller than the requested size,
4839resize2fs will attempt to extended the file so that programs like
4840e2fsck will not complain that the file is too small.
4841
4842Resize2fs will print the actual new size of the filesystem when it is
4843finished resizing.
4844
4845Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4846information on big-endian systems.
4847
4848
4849Programmer's notes:
4850-------------------
4851
4852Fixed collisions with C++ reserved words.
4853
4854Added portability fixes for building e2fsprogs on the HURD and AIX.
4855
4856Added the ext2ed program for creation of test cases.  (ext2ed has many
4857limitations and bugs which make it unsuitable for production use.)
4858
4859The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4860flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4861name_len field is byte swampped on big-endian machines, since in the
4862V2 structure, name_len is a char field which is doesn't need to be
4863byte swapped --- except if an old-style kernel had byte-swapped the
4864name_len field as part of the V1 structure.
4865  
4866
4867E2fsprogs 1.27 (March 8, 2002)
4868==============================
4869
4870The warning messages for mke2fs now go to standard error.
4871
4872Fixed to make sure "make check" runs all of the test programs with
4873LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4874
4875The mke2fs program checks the boot sector for the BSD disk label, and
4876avoids erasing it if it is there.
4877
4878Fixed a bug in e2fsck which caused it to core dump if the journal
4879inode was missing when it was supposed to be there.
4880
4881E2fsck now prints ranges in pass 5 when printing deltas for the block
4882and inode bitmaps.
4883
4884Debugfs's "ls -l" command now will print out the file type information
4885in the directory entry.
4886
4887Create man pages and hard links for fsck.ext3 and mkfs.ext3.  If
4888mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4889
4890Debugfs can now examine the experimental directory indexing
4891information.
4892
4893Fixed bug in debugfs which caused it to core dump if modify_inode is
4894called without an open filesystem.
4895
4896The debugfs lsdel command now runs its output through a pager first.
4897
4898When installing manual pages, remove the compressed manual pages first.
4899
4900Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4901
4902Fix the 2.4 resource limitation workaround introduced in 1.26 which
4903actually broke things on mips32, sparc32, and Alpha platforms.
4904
4905Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4906(which is required by the newer libintl libraries).
4907
4908Programmer's notes:
4909-------------------
4910
4911Fixed various gcc -Wall complaints.
4912
4913Fixed a few memory leaks in the e2fsck journaling code, and in the
4914ismounted code checking for a swap device.
4915
4916Add new inode I/O abstraction interface which exports an inode as
4917an I/O object.
4918  
4919Exported ext2_file_flush as a public interface.
4920  
4921In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4922
4923Lots of small random portability fixes to make e2fsprogs build under
4924AIX --- even without the 5L compatibility toolkit, and even using the
4925uber-crippled AIX native C compiler.
4926
4927
4928E2fsprogs 1.26 (February 3, 2002)
4929=================================
4930
4931Dumpe2fs will keep going now if the bad block inode can't be read.
4932(Previously it stopped with a fatal error.)
4933
4934E2fsck will now give an opportunity to run the journal even if the
4935recovery flag is not set.  This is the default behaviour if e2fsck is
4936using a backup superblock, since the needs_recovery flag will never be
4937set in the backup superblock copies.
4938
4939E2fsck now automatically finds the backup superblock/group descriptors
4940even when the primary superblock is completely destroyed for 2k and 4k
4941filesystems.  (Previously it just guessed/assumed that we were dealing
4942with a 1k filesystem in that case, and users had to manually specify
4943the backup superblock number.)
4944
4945Fixed a bug in e2fsck where it dereferences a null pointer when there
4946is a problem opening a filesystem in preen mode.
4947
4948E2fsck now handles external journals correctly; previously it trashed
4949the external journal device if the journal needed to be replayed.
4950
4951Work around ulimit incompatibility problem caused by recent 2.4
4952kernels; the unix IO module will automatically try to set any resource
4953limits to be infinite on startup.
4954
4955Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4956bitmap if it wasn't present and the blocksize was 2k or 4k.
4957 (Addresses Debian Bug #116975)
4958
4959E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4960clearing the new V2 fields if they do not make sense or if the ext3
4961superblock is version 1 superblock.
4962
4963E2fsck will automatically relocate the ext3 journal from a visible
4964file (i.e., /.journal) to an hidden inode if the filesystem has been
4965opened read/write.  This allows the users to add a journal while the
4966filesystem is mounted, but the next time the system is rebooted, the
4967journal file will disappear.  This avoids problems with backups,
4968stupid operators with superuser bits, etc.
4969
4970Fix a bug in fsck where it would not support a filesystem type of
4971"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4972
4973Fsck now supports fstab entries of the form "ext3,ext2".  It will also
4974automatically identify reiserfs filesystems.
4975
4976The number of processes spawned by fsck can now be limited using the
4977FSCK_MAX_INST environment variable.
4978
4979Fsck now searchs the LVM proc hierarchy to find logical volumes which
4980should be searched for  UUID and label information.
4981
4982Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4983limit if at all possible, when opening a block device.  (The filesize
4984limit shouldn't be applied against writes to a block device.)
4985
4986In mke2fs and e2fsck, specifying the -c option twice will now do
4987a read/write test on the disk.  Update the man pages to encourage
4988using the -c option, and to discouraging running badblocks separately,
4989since users tend to forget to set the blocksize when running 
4990badblocks.
4991
4992Mke2fs now automatically clears the immutable attribute on a
4993pre-existing .journal file left over from a previous failed attempt to
4994add a journal to an alreadyy-mounted filesystem.
4995
4996Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4997operation failed.
4998
4999Mke2fs now creates the lost+found directory with permissions of 0700,
5000so that files that had previously lived in protected directory are
5001safe if they get dropped in lost+found and the system administrator
5002doesn't deal with immediately.  (Addresses Debian #bug 118443)
5003
5004Mke2fs and e2fsck (and all programs that use the
5005ext2fs_check_if_mounted function) will now properly identify that a
5006device is mounted, even in cases where devfs has confused things with
5007multiple devices names with the same identity, or if a dim-witted
5008system administrator has done something stupid like creating device
5009file aliases in their home directory.  Also now checks for swap devices
5010by using /proc/swaps.  (Addresses Debian bug #106622)
5011
5012Added a new option (-T) to tune2fs which sets the time a filesystem
5013was last checked.
5014
5015Speed up e2image when creating sparse raw image files by optimizing
5016away excess lseek() system calls.
5017
5018Fix support of large (> 2GB) files when used as a filesystem in
5019mke2fs, tune2fs, debugfs, and findsuper.
5020
5021Debugfs's stat and icheck commands now properly deals with large (>
50222GB) files.
5023
5024Debugfs's set_super_value command now prints out the list of valid
5025superblock fields which can be set using the command.
5026
5027Debugfs's rm and kill_file command now updates the superblock free block
5028and inode counts, thus keeping the filesystem consistent.
5029
5030Debugfs's lsdel command now takes an optional argument which allows
5031the user to only see the most recently deleted files.
5032
5033A new command (undel) was added to debugfs which automates
5034undeleting a deleted inode and linking it back to a directory.
5035
5036Debugfs's ls command now takes a new option, -d, which lists 
5037deleted directory entries.
5038
5039Debugfs's testb, freeb, setb, and find_free_block commands now take an
5040optional count argument.
5041
5042Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5043be used to signal that a particular inode should not be eligible for
5044tail-merging --- this is needed for programs like LILO.
5045
5046The findsuper (an unreleased, uninstalled utility program) has been
5047improved to add extra validity checks and to add a progress meter.
5048(It is still an unsupported program; the officially supported way to
5049recover from a trashed partition table is to use gpart; findsuper is
5050for wizards only.  :-)
5051
5052Debugfs was fixed to compile with "configure --disable-swapfs".
5053
5054Cleaned up various manual pages.   (Addresses Debian bug #119624, #120171)
5055
5056Added new translation file for Turkish.
5057
5058Programmer's notes:
5059-------------------
5060
5061Fix general gcc -Wall complaints.
5062
5063E2fsprogs (mostly) works with the dietlibc.
5064
5065The programming texinfo file has been expanded to include description
5066of additional libext2fs functions.  (Still not compeltely done, but a
5067lot of the more important functions have been documented.)
5068
5069Added a umask structure to struct_ext2_filsys, which currently only
5070modifies the behaviour of ext2fs_mkdir(), but if we add any file
5071creation functions to libext2fs, we should also make sure they respect
5072the umask setting.
5073
5074The build-rpm script was fixed to be a bit more safe.
5075
5076The tests' Makefile now has a way of automating test case creation 
5077for e2fsck, using "make testnew".
5078
5079Created a new function, ext2fs_dir_iterate2 which passes more
5080information to the callback function (identical to the one used by
5081ext2fs_dblist_dir_iterate).  The directory iterator functions take a
5082new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5083directory entries.  If the directory entry is deleted, the callback
5084function will be called with the entry paraemter set to
5085DIRENT_DELETED_FILE.
5086  
5087Added new functions, ext2fs_inode_alloc_stats and
5088ext2fs_block_alloc_stats, which takes updates block/inode allocation
5089statistics in the bitmaps, block group descriptors, and superblock
5090when inodes or blocks are allocated or deallocated.
5091
5092
5093E2fsprogs 1.25 (September 20, 2001)
5094===================================
5095
5096This is primarily a bug-fix release; no new features were added, but
5097there are a number of embarassing bug fixes and cleanups applied.
5098
5099Fix a bug mke2fs which causes stack garbage to be written to disk when
5100zapping disk sectors.  (This bug could cause mke2fs to core dump for
5101some kernels, I suspect with security enhancement patches.)
5102
5103Remove unneeded #include of <linux/config.h> which was breaking
5104building e2fsprogs on the Hurd.  (Addresses Debian bug #112414.)
5105
5106Updated tune2fs man page to reflect the fact that adding or removing a
5107journal doesn't require running e2fsck.
5108
5109Remove use of AC_REQUIRE from autoconf which had been used to prevent
5110AC_CANONICAL_HOST from being called twice; unfortunately this causes
5111recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5112used outside of autoconf macros.  Fortunately, it doesn't seem to be
5113necessary any more, anyway.
5114
5115E2fsck will now not fall back to an alternate superblock if the user
5116specifies the superblock location explicitly on the command-line.
5117This allows easier recovery from a situation where the primary
5118superblock and block groups are slightly corrupted, but the backup
5119superblocks are completely broken.  
5120
5121Fix problem which caused compile_et and mk_cmds to blow up if
5122e2fsprogs was in a directory with a pathname that contained spaces.
5123
5124We are now more paranoid about checking the entry in /etc/mtab to make
5125sure the filesystem is really mounted, since some broken distributions
5126(read: Slackware) don't initialize /etc/mtab before checking non-root
5127filesystems.  (Slackware also doesn't check the root filesystem
5128separately, and reboot if the root filesystem had changes applied to
5129it, which is dangerous and broken, but there's nothing I can do about
5130that.)
5131
5132Make UUID library C++ friendly by adding appropriate extern "C"
5133declarations and using const in the function declarations.
5134
5135Fix up the com_err texinfo file so that it can product a valid info
5136file (previously, it could only be used to generate paper
5137documentation using texinfo.tex).
5138
5139
5140E2fsprogs 1.24a (September 2, 2001)
5141===================================
5142
5143Fix brown-paper bug in mke2fs which caused it to segfault when
5144printing the version string.
5145
5146
5147E2fsprogs 1.24 (August 30, 2001)
5148================================
5149
5150Revert the BLKGETSIZE64 support, since for some distributions, this
5151ioctl has been used by an unofficial kernel patch to update the last
5152sector on the disk, and this was causing disk corruption problems as a
5153result.
5154
5155Mke2fs is now more careful about zapping swap space signatures and
5156other filesystem/raid superblock magic values so that programs like
5157mount who try to use hueristics to determine the filesystem type of a
5158partition are less likely to be confused.
5159
5160E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5161regular file (since Andreas Dilger's on-line resizing tools will set
5162its mode bits).
5163
5164Fixed some minor texinfo, man pages nits for spelling errors,
5165texinfo warnings, etc.  (Addresses Debian bug #110621.)
5166
5167E2fsprogs program no longer print the filesystem version number
5168(i.e. 0.5b), since it only confuses people and doesn't serve any real
5169purpose.
5170
5171E2fsck will once again compile under libc5, since it will supply its
5172own version of strnlen if necesssary.
5173
5174mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5175when specifying the external journal device.  tune2fs will also search
5176devices looking for the externla journal debice when removing.  
5177
5178E2fsprogs 1.23 (August 15, 2001)
5179================================
5180
5181Add initial support for extended attributes (EA); e2fsck will
5182correctly handle a filesystem with EA's and check the EA blocks for
5183corruptions.
5184
5185E2fsck's symlink sanity checking has been cleaned up.  It now checks
5186the i_size value of fast symlinks, and checks for immutable flags
5187being set of symlinks, etc.
5188
5189E2fsck now offers to clear inodes which are special files that have a
5190non-zero i_blocks or i_size field.  (The i_size field check was in the
5191previous version of the code, but due to a bug it didn't offer to
5192clear the inode unless i_size and i_size_high were both non-zero.)
5193
5194E2image can now create "raw" image files, which only contain the
5195filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5196debugfs, etc., can be run directly on the raw image file.
5197
5198Add support for the 64-bit block device patches.
5199
5200Fixed bugs in creating external journals with a 1k blocksize.
5201
5202Add initial support for external journals (so long as the external
5203journal only supports a single filesystem) in e2fsck.
5204
5205Remove requirement for needing to run fsck on a filesystem after
5206removing a journal (either internal or external).
5207
5208The man pages now document how to create and manage external journals.
5209
5210Speed up the check of an ext3 filesystems by avoiding a needless flush
5211of all of the superblock and block group descriptors.
5212
5213Speed up creating an internal journal using tune2fs in the case where
5214the filesystem has a lot blocks already allocated.
5215
5216Tune2fs has been fixed to make sure that only error messages go to
5217stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5218
5219Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5220now not set the sparse_super feature.  (Addresses Debian bug #108165)
5221
5222Add support in fsck for the filesystem type "auto".
5223
5224Fsck -A will not try to interpret device names for filesystems which
5225have a pass number is 0.  (Addresses Debian bug #106696).
5226
5227Fsck prints a warning message if now valid filesystems are passed to
5228it.  (Addresses Debian Bug #107458.)
5229
5230E2fsck now gives an explicit warning if there filesystem still has
5231errors at the end of the run. (Addresses Debian bug #104502)
5232
5233E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5234reflects an error.  E2fsck will also not run the orphan list if the
5235filesystem contains errors, since the orphan list might be corrupted.
5236
5237E2fsck now prints the number of large files when given the -v option.
5238
5239Fixed minor memory leaks in e2fsck.
5240
5241Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5242
5243
5244E2fsprogs 1.22 (June 22, 2001)
5245==============================
5246
5247Fixed a bug in e2fsck's handling of orphan inodes which are special
5248files (i.e., block/character device files, named FIFO's, etc.).
5249
5250Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5251tune2fs to fail at adding a journal to a mounted filesystem.
5252
5253Fixed a few big-endian bugs in e2fsprogs
5254	* The directory block functions were accidentally reporting
5255		some directories as corrupted when they weren't.
5256	* If e2fsprogs is compiled --disable-swapfs, the C language 
5257		equivalents weren't being included for big-endian platforms.
5258		(Fixes Debian bug #101686).
5259
5260Fixed a Hurd compilation problem.  (Addresses Debian bug #101361)
5261
5262Programmer's notes:
5263-------------------
5264
5265Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5266ioctls, and allow them to be defined for non-i386 platforms.
5267
5268The uuid.h header file is now protected against multiple inclusions.
5269
5270E2fsprogs is now being developed using BitKeeper.  Changed the test
5271scripts to deal with BK's stripping CR characgters from text files,
5272and changed the top-level Makefile.in to avoid including BitKeeper
5273files when generating the source tarball.
5274
5275
5276E2fsprogs 1.21 (June 15, 2001)
5277==============================
5278
5279Added new configure flags which allow a subset e2fsprogs to be built;
5280this is most useful for boot floopies, since the resulting shared
5281libraries and programs are slimmed down by removing features that
5282aren't necessary for a boot floppy.  The new flags that were added
5283are: --disable-swapfs, which removes support for byte swapping old
5284legacy PPC/68k filesystems, --disable-debugfs, which removes support
5285for debugfs from the libext2fs library, --disable-imager, which
5286removes support for the e2image program, and --disable-resizer, which
5287removes support for resize2fs.
5288
5289E2fsck now prints the number of mounts or days elapsed since the last
5290check when e2fsck is forced to check an otherwise clean filesystem.
5291
5292Tune2fs now prints an informative message about how often a filesystem
5293will be checked when adding a journal to the filesystem, to remind the
5294user that he/she may want to adjust those parameters using tune2fs
5295-c/-i.
5296
5297Worked around hurd brain-damage which causes e2fsck to sometimes
5298believe a filesystem is the root filesystem based on device numbers
5299(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5300violation).
5301
5302Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5303erroneous error with the -F option was specified.
5304
5305Fixed a ext3 recovery bug in the revoke handling; synchronized with
5306ext3 0.7a.
5307
5308Fixed two bugs in e2fsck's handling of dup block handling, dealing
5309with relatively uncommon edge cases: a directory with an indirect
5310block which is claimed by another file, and when the last inode in the
5311filesystem has blocks claimed by another file.
5312
5313E2fsck now checks to see if the i_size field of a fast symlink is too
5314big, and offers to clear the symlink if so.
5315
5316E2fsck now checks to see if i_size_high of special files is non-zero,
5317and offers to clear i_size_high.
5318
5319Fix e2fsck's handling of incompatible journal flags so that the user
5320has chance to abort, and then has the option to clear out the journal
5321entirely.  (Addresses Debian bug #98527.)
5322
5323Fixed a bug in fsck which could cause it to core dump if a mix of
5324standard and non-standard device names are used in /etc/fstab.
5325(Debian bug #100559)
5326
5327Fixed a bug in debugfs which caused read errors when copying a file to
5328not be noticed.
5329
5330The debugfs set_super_value command can now modify the s_lastcheck field.
5331
5332Fixed a bug in lsattr and chattr which was accidentally introduced in
53331.20 to support > 2GB files; both lsattr and chattr wasn't reading
5334directories correctly because the change modified the layout of struct
5335dirent to be incompatible with the libe2p shared library.
5336
5337Cleaned up the mke2fs manual page and included a discussion about why
5338it's good to periodically check the filesystem even when journaling is
5339enabled.
5340
5341Programmer's notes:
5342-------------------
5343
5344Fix general gcc -Wall complaints.
5345
5346The types needed by the ext2 header files are now provided by
5347lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5348
5349Integers are now preferred to longs when trying to find a 32-bit type
5350in ext2_types.h.  Also, if linux/types.h has already been defined,
5351don't try to redefine the types.
5352
5353Fixed make depend script so that it automatically corrects the
5354pathname cleanups performed by make -M, so I don't have to fix them up
5355by hand.
5356
5357Fixed the d_loaddump test case to be more robust, and not depend on
5358bash'isms.
5359
5360Removed debugfs's dependence on pread(), which was accidentally
5361intrudced in e2fsprogs 1.20
5362
5363Fixed a performance bug in the libext2fs's icount routine; the size
5364estimate of the icount array was incorrectly being calculated.
5365
5366Removed use of the badblocks compatibility functions in the e2fsprogs
5367programs.
5368
5369Added paranoia code which protects against strange cases where /etc
5370isn't on the root filesystem, or if /etc/mtab doesn't exist.
5371
5372The header file ext2_types.h is now installed.
5373
5374Autoconf is used to determine when we are on big-endian machines,
5375instead of doing run-time tests, to save a few bytes of code.
5376
5377The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5378functions are no longer inline functions, which saves space and
5379doesn't really cost any real performance.
5380
5381The ext2fs library no longer depends on the e2p library.  (What need
5382there was of it --- namely, fsetflags, was coded in-line).
5383
5384Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5385when the user is stupid and tries compiling the package using "make
5386install" as root.
5387
5388Miscellaneous code cleanups:
5389	* Added missing files from Makefile.in's SRCS file, so that 
5390		their dependencies would be properly calculated.
5391	* Removed redundant code
5392	* Fixed comments in code
5393	* Removed no-longer unneeded argsused #pragma.
5394
5395
5396E2fsprogs 1.20 (May 20, 2001)
5397=============================
5398
5399Add support for replaying the ext3 journal purely in user mode,
5400including handling the orphaned inode list.  Used code contributed by
5401Andreas Dilger, with bug fixes and the orphaned inode handling done
5402by Theodore Ts'o.
5403
5404The mke2fs and tune2fs programs can create or modify a filesystem to
5405include an ext3 journal.  Tune2fs also can be used to remove an ext3
5406journal from a filesystem.
5407
5408E2fsck will now check for the existence of a linked list of orphan
5409inodes in the superblock, and clear those inodes before starting the
5410rest of the filesystem check (but after the journal playback).
5411
5412E2fsck now validates the file descriptor passed to the -C option,
5413which saves against the completion bar getting written to an
5414unexpected location, such as the disk being checked.  (Debian
5415bug/wishlist #55220)
5416
5417E2fsck will now bump the filesystem revision number from zero to one
5418if any of the compatibility bits are set.
5419
5420Fixed a bug where a badly corrupted directory on a big endian system
5421could cause e2fsck to die with a bus error.  The
5422ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5423the ext2 library now does alignment sanity checks on the rec_len field
5424of the directory entry before using it.
5425
5426The ext2 library has been enhanced to make tune2fs safe to run on
5427mounted filesystems.  (Users could usually get away with using tune2fs
5428on mounted filesystems before, but with the advent of ext3 and
5429journaling, it became important to make tune2fs was *really* safe for
5430use even when the filesystem being modified is mounted.)  E2label is
5431now implemented by tune2fs using an argv[0] dispatch, so that e2label
5432is also now safe for use on mounted filesystems.
5433
5434Added a new program, e2image, which creates a backup of critical ext2
5435filesystem data structures.  The generated image file can be examined
5436using dumpe2fs and debugfs.  In the future, e2fsck will be able to use
5437the image file to help recover very badly damaged filesystems.
5438
5439Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5440no longer cause e2fsck to bomb out.  Also treat files > 2GB as being
5441large file when deciding whether or not the filesystem has large files.
5442
5443Fixed lsattr and chattr so that they work correctly on large files.
5444(Fixes Debian bug #72690.)
5445
5446Removed limitation in get_device_size() which imposed a one terrabyte
5447filesystem limitation.  (Most 2.2 kernels still have a signed int
5448problem which cause 1 TB block device limitation.  Fortunately, the
5449kernel patches to fix this are much easier than fixing the 2TB
5450limitation in the kernel.  :-)
5451
5452A max_mount_count of zero is now treated as if no mount count were
5453set.  (Previously, no mount count was indicated by using -1, and a
5454mount count of zero caused e2fsck to always be run.)
5455
5456Mke2fs supports two new filesystem types largefile and largefile4.
5457
5458Mke2fs now adds some randomness in s_max_mount_count so that multiple
5459filesystems won't be all checked at the same time under normal
5460operations.
5461
5462Fixed bug in the progress bar printing code which could cause e2fsck
5463to core dump on an illegal filesystem.
5464
5465Fixed bug in fsck which could allow more than one instance of e2fsck
5466to be printing a progress bar.  (Debian bug #65267)
5467
5468Fsck using a UUID or a LABEL specifier will work even if devfs is
5469compiled into the kernel and not mounted.  If the pathnames in
5470/proc/partitions are incorrect, fsck will search /dev for the correct
5471device (using the new ext2fs_find_block_device library function).
5472Fsck now also checks the RAID devices first so that they are properly
5473found when they are in use.  Support has also been added to support
5474additional IDE disks and the DAC 960 device names.  (Debian bug #94159)
5475
5476Fixed a bug in fsck which caused it not deal properly with 16
5477byte long filesystem labels.
5478
5479Fsck's -t option has been made a lot more flexible.  The semantics for
5480what happens if a comma-separated list to fsck has been regularized,
5481and it is now possible to filter what filesystems will get checked
5482based what is in the filesystem's fstab entry's option field.  (Debian
5483bug #89483.)
5484
5485The dumpe2fs program can now print out the group description
5486information in hex, and also prints the location of the superblock and
5487block group descriptor for those block groups that have them.
5488
5489Mke2fs now clears the ext2 superblock before it starts creating a
5490filesystem, so that the superblock magic number is only written if the
5491filesystem creation process successfully completes.
5492
5493The debugfs program's stat command now pretty-prints the blocks used
5494by an inode so that it's more compact and informative.
5495
5496The debugfs stats command now uses the same libe2p code (which is used
5497by dumpe2fs) to print the superblock header information.  This is more
5498complete, and it avoids a bit of code duplication.
5499
5500Added a new debugfs command, set_super_value (ssv) which allows the
5501user to set arbitrary superblock fields.
5502
5503Debugfs was extended to support inode numbers in hex (by prefixing
5504them with 0x), and so that modify_inode can set the inode generation
5505number.  Also, there is now a new function command called logdump
5506which will dump an ext3 journal.
5507
5508Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5509debugfs.
5510
5511Debugfs's dump command now stops immediately upon reporting a disk
5512read error.  (Fixed a bug in ext2fs_file_read library routine which
5513caused debugfs not to stop.)  (Debian bug #79163)
5514
5515On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5516checked before /etc/mtab is used, since /proc/mounts is more likely to
5517be accurate.
5518
5519Added portability fixes for Solaris and Linux/ia64.
5520
5521Various manual pages were clarified and cleaned up.  (Fixed debian
5522bugs #63442, #67446, and #87216)
5523
5524
5525Programmer's notes:
5526-------------------
5527
5528The e2fsck message printer now supports %Iu and %Ig, which will print
5529out the inode's user and group owners, respectively.
5530
5531E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5532that no longer dependent on the system having the correct version of
5533the kernel header files.
5534
5535Added a new function to libext2, ext2fs_find_block_device(), which
5536searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5537device given its device number.
5538
5539Added a new function to libext2, ext2fs_sync_device, which centralizes
5540all of the places which might try to use the BLKFLSBUF or FDFLUSH
5541ioctls (and usually failing to define them since the system header
5542files don't usually do this for us, and we're trying to avoid usage of
5543kernel include files now).
5544
5545Added new utility programs in tests/progs: random_exercise and
5546hold_inode.  They aren't built by default; they're useful for
5547exercising ext3 filesystem code.
5548
5549Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5550the filesystem close functions to only update the superblock, and to
5551not touch the block group descriptors.  Needed by tune2fs when
5552modifying a mounted filesystem.
5553
5554Got rid of struct ext2fs_sb and replaced it with the standard struct
5555ext2_super_block from include/linux/ext2_fs.h.  Note: this may break
5556source (but not binary) compatibility of some users of the ext2
5557library.  Those applications should just simply do a global search and
5558replace of struct ext2fs_sb with struct ext2_super_block, and include
5559the new header file <ext2fs/ext2_fs.h> which defines it.
5560
5561The ino_t type has been renamed ext2_ino_t to protect applications
5562that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5563inexplicably changes ino_t(!?).  So we use ext2_ino_t to avoid an
5564unexpected ABI change.
5565
5566The Makefiles have been reworked so that "make check" can be run from
5567the top-level Makefile.
5568
5569Fix general gcc -Wall complaints and removed dead code.
5570
5571Remove use of NOARGS, because we assume everyone does ANSI C these
5572days.
5573
5574Added build-rpm script from sct.
5575
5576New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 
5577to support e2image.
5578
5579New function ext2fs_flush_icache which must be called if the
5580application program modifies the inode table blocks without going
5581through ext2fs_write_inode() interface.
5582
5583New ext2fs_check_mount_point() function, which will return the mount
5584point of a device if mounted.
5585
5586The io_channel abstraction now has an optional interface,
5587io_channel_write_range, which allows specific byte ranges to be
5588written.  
5589
5590The unix_io IO channel now supports write-through caching, so that
5591journal creation is more efficient.
5592
5593Added x86 assembly language routines to support byte swapping, to
5594reduce executable size.
5595
5596Fixed bug in the utility program subst so that it's possible to
5597replace a substitution variable with a zero-length string.
5598
5599Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5600slipped into some of the problem number.
5601
5602E2fsprogs 1.19 (July 13, 2000)
5603==============================
5604
5605Release the resize2fs program since the timeout before it could
5606be released under the GPL has finally expired.
5607
5608Add experimental support needed for the ext2 compression patches.
5609This requires compiling e2fsprogs with the --enable-compression flag
5610to the configure script.
5611
5612Added ext3 journalling support.  E2fsck will run the journal (if
5613necessary) by temporarily mounting the filesystem.  /sbin/fsck.ext3 is
5614installed as a symlink to e2fsck.  Fsck has been taught about ext3,
5615and treats it the same as ext2 in terms of the progress bar logic.
5616Dumpe2fs will display the superblock journaling information if the
5617filesystem has a journal.  The ext2 library will now permit opening an
5618ext3 filesystem with the recovery flag set.  This is necessary for
5619on-line dump's to work correctly, but there may be issues with this
5620working well since ext3 is much less agressive about syncing blocks to
5621the filesystem, since they're safe on the journal.
5622
5623Tune2fs and e2fsck have been changed to allow the mount_count check to
5624be disabled by setting max_mount_count to -1.  (This was already
5625supported by the kernel.)
5626
5627Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5628are used for ext3 as well.
5629
5630Added internationalization support for e2fsprogs; must be enabled
5631by passing --enable-nls to configure.
5632
5633Always use the provided ext2fs header files to insulate ourselves from
5634kernel version changes.  Which include files are used by e2fsprogs
5635have also been cleaned up to improve portability.
5636
5637Limit the number of times that e2fsck updates the progress bar so that
5638people who are booting using a 9600 baud console don't get swampped by
5639too many updates.
5640
5641Improved the loop detection algorithm in e2sck's pass #3 so that it is
5642much, much faster for large filesystems with a large number of
5643directories.
5644
5645The memory footprint for e2fsck is now slightly smaller than before.
5646
5647E2fsck now checks if special devices have a non-zero size, and offers
5648to clear the size field if it finds such an inode.  
5649
5650E2fsck now checks if special devices have the append-only flag set,
5651and offers to clear the inode.
5652
5653E2fsck now properly handles some "should never fail" cases during a
5654bitmap copy in pass5.
5655
5656E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5657
5658E2fsck now calculates the correct location of the backup superblock in
5659the case of filesystem blocksizes > 1k.
5660
5661Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5662which normally didn't cause problems under most filesystem parameters,
5663but could cause a valid superblock to be rejected in extreme cases.
5664Other checks for validating superblock values were made more
5665stringent.
5666
5667Added non-destructive write testing to the badblocks program, courtesy
5668of David Beattie.  The badblocks also now has an option to input the
5669current set of bad blocks, so that known bad blocks are skipped to
5670speed up the badblocks test.  There is also a persistent rescan
5671feature which causes badblocks to run until it has completed some
5672number of passes without discovering any new bad blocks.
5673
5674Badblocks now checks to see if the device is mounted and refuses to do
5675the tests involving writing to the device if it is mounted.  Also,
5676badblocks now allows the number of blocks to be checked to be
5677defaulted to the size of the partition.
5678
5679Fixed a bug in fsck which didn't allow non-root users to be able to
5680check filesystems if there were any LABEL= or UUID= entries in
5681/etc/fstab.
5682
5683The Hurd doesn't support the filetype filesystem feature.  The mke2fs
5684program now makes sure that for the Hurd, the filestype feature is
5685turned off.  E2fsck will check to see if the filetype feature is
5686turned on for Hurd filesystems, and offer to turn off the feature.
5687
5688Mke2fs now has a safety check to make sure the number of blocks do not
5689exceed 32 bits even on a 64 bit platform.
5690
5691Really fixed a bug in fsck to allow "fsck -As" to run interactive
5692fsck's.  (For those people who like to do interactive fsck's in the
5693/etc/rc scripts!?!)
5694
5695Debugfs has a few new features: the rdump command, which will do a
5696recursive dump of a directory and all of its contents, and the lcd
5697command which does a local chdir (much like the ftp command of the
5698same name).  In addition, the debugfs program and the open_filesystem
5699command now takes three new options: -b and -s, which allows the
5700blocksize and superblock location to be specified, and the -c option
5701which is used in catastrophic situations where the block group
5702descriptors are corrupt.  If the -c option is specified, debugfs will
5703skip trying to read in the block and inode bitmaps.
5704
5705Debufs's lsdel command was fixed to handle bad blocks in the inode
5706table.
5707
5708A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
57094 digit years.
5710
5711General improvements in error messages
5712
5713  - Mke2fs prints a sane error message if the partition size is zero
5714	(usually because the partition table wasn't reread by the
5715	kernel due to the partition being busy), instead of "invalid
5716	argument passed to ext2 library while initializing superblock".
5717
5718  - Fsck now prints more self-explanatory message if an invalid UUID=
5719	or LABEL= specification is passed to it.
5720
5721UUID library changed to use the LGPL.
5722
5723Fixed a bug in the UUID library where very rapid calls to the
5724time-based UUID generator could cause duplicate UUID's to be returned.
5725This was not a problem for e2fsprogs, but it could be a problem for
5726other users of the library.
5727
5728Make the UUID library more robust in the face of missing or an
5729improper /dev/urandom or /dev/random files.
5730
5731Added some random portability fixes for Solaris.
5732
5733Some minor man page updates.
5734
5735Fixed a memory leak in the ss library.
5736
5737
5738Programmer's notes:
5739-------------------
5740
5741We now try to use lseek64 and open64 from the LFS if possible.
5742
5743The 3rd parameter in e2p's print_flags is now a flags word, instead of
5744a boolean option.
5745
5746The mark and unmark bitmap functions now return the previous state of
5747the bit that was being changed, which is useful for some speed
5748optimizations.
5749
5750The following functions have been added to enhance the badblocks list
5751handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5752ext2fs_badblocks_equal.
5753
5754The ext2 header files now have the latest journalling fields to the
5755superblock.
5756
5757The ext2fs_mkdir function in libext2fs now properly backs out of error
5758conditions robustly.
5759
5760Cleaned up makefiles:
5761  - to cleanly  compile with the -j flag.
5762  - so distclean removes all generated files.
5763  - so in case of an error while installing header files, the make aborts.
5764
5765Fix test_script so that it works correctly when compiling in the
5766source directory.
5767
5768The random UUID generation routine has been made slightly better in
5769the case where /dev/random doesn't exist.  (Use of randomly-based UUID
5770is still not recommended if /dev/random doesn't exist, however; it's
5771better to use the time/ethernet MAC address UUID in this case.)
5772
5773Clean up the build process so it's more friendly in case of missing
5774directories.
5775
5776The ext2fs header file can now be #include'd into C++ programs.
5777
5778The e2p.h header file is now installed.
5779
5780Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5781
5782
5783
5784E2fsprogs 1.18 (November 10, 1999)
5785==================================
5786
5787Fix a core dumping bug in e2fsck if an imagic inode is present or
5788(more rarely) if the filesystem is badly corrupted enough that e2fsck
5789has to restart pass 1 processing.  E2fsck now closes the filesystem
5790before freeing a large number of its data structures, so in the case
5791of future memory faults, at least the fixed filesystem will be fully
5792written out.
5793
5794If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5795imagic inode, it will offer to clear the imagic flag.
5796
5797E2fsck will now offer to clear the immutable flag on special files
5798(device/socket/fifos) when running it in non-preen mode.
5799
5800E2fsck will now set the filetype when creating /lost+found, and when
5801connected orphaned inodes to /lost+found.
5802
5803Debugfs's ncheck and icheck commands now handles the case where there
5804are bad blocks in the inode table without bombing out.
5805
5806The badblocks list processing code has been made more efficiently for
5807appending a large number of (ordered) badblocks to the badblocks list.
5808
5809Some minor man page updates.
5810
5811Fsck now allows interactive e2fsck's when using fsck -As (not a common
5812mode, but some people like to do this in boot scripts for silly reasons).
5813
5814Programmer's notes:
5815-------------------
5816
5817The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5818with the problem code convention.
5819
5820The badblocks list regression test program has been updated to work
5821with previously made API name changes.
5822
5823The ext2fs_free() command now uses the new badblocks API to avoid
5824using the compatibility layer.
5825
5826Added new regression test cases; the run_e2fsck test script now
5827supports the ability for a test case to run a prepratory command
5828before running e2fsck.
5829
5830E2fsprogs 1.17 (October 26, 1999)
5831=================================
5832
5833Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5834infinite loop.
5835
5836Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5837thus potentially causing problems if a binary UUID contained a NULL
5838character.
5839
5840E2fsck now uses stricter checks for directory entries in pass 2:
5841zero-length filenames are not allowed; neither are 8 byte long
5842directory entries.
5843
5844The debugfs "dirty" command now clears the filesystem valid bit.
5845(Previously this just set the dirty-as-in-needs-writing-out-to-disk
5846bit in the in-core superblock image.  The new functionality is more
5847what the user expects, and is more useful.)
5848
5849Added a debugging hook to test parallel fsck; if the environment
5850variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5851will be checked in parallel when they normally would not be.
5852
5853Programmer's notes:
5854-------------------
5855
5856Fixed some #ifdef's for compilation under the Hurd OS.
5857
5858Fixed minor W2K compatibility problems.
5859
5860Fixed some miscellaneous GCC warnings.
5861
5862
5863E2fsprogs 1.16 (October 22, 1999)
5864=================================
5865
5866Fixed a race condition bug in fsck; when printing a progress bar, if
5867checking multiple filesystems in parallel, it was possible for fsck to
5868send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5869handler, which would cause it to terminate with a signal 10.
5870
5871E2fsck now properly handles filesystems that have the
5872INCOMPAT_FILETYPE feature turned on.  It can be used to convert a
5873filesystem into using or not using FILETYPE feature.
5874
5875E2fsck now properly handles filesystems that have the IMAGIC feature
5876turned on (this is used on Linux AFS servers).
5877
5878The mke2fs program now creates filesystems that have the filetype and
5879sparse_superblock features enabled by default, unless it is run on a
5880pre-2.2 kernel.  These features are not supported by a pre-2.2 kernel,
5881so there is now a new flag -O which allows the user to specify with
5882which features she would like to create the filesystem; "mke2fs -O
5883none" will create a filesystsem compatible with 2.0 kernels.
5884
5885The tune2fs program now has a -O option which allows the user to set
5886and reset "safe" filesystem features.  Currently, the only ones which
5887allows to be modified are the filetype and sparse_superblock features.
5888Note setting or clearing either feature will require running e2fsck on
5889the filesystem afterwards.  (n.b. Clearing the sparse_superblock feature
5890requires that there is enough free space on the filesystem for the
5891extra superblocks which will be created by e2fsck.)
5892
5893Debugfs can now set and print filesystem features in the superblock
5894using the "features" command.  Dumpe2fs will print out the complete
5895set of features when listing the superblock.
5896
5897Dumpe2fs has new options -f (force) and -h (header-only).
5898
5899Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5900message to come up.  This could happen when decrementing or
5901incrementing a link count could result in an overflow.
5902
5903Fixed a bug in e2fsck where the block count on the lost+found
5904directory would not be properly incremented when the directory was
5905expanded to the point where an indirect block needed to be allocated.
5906
5907E2fsck now makes some additional sanity checks on the superblock to
5908avoid crashing or giving a memory allocation error if some of the
5909values in the superblock are unresonable (but the superblock otherwise
5910looks valid).
5911
5912Fixed a bug in e2fsck where a very badly corrupted filesystem might
5913require two passes to completely fix the filesystem.  This happened if
5914an inode claimed blocks that was part of the filesystem metadata
5915(typically, when garbage was written into an inode table or indirect
5916block, since this kind of filesystem corruption normally doesn't
5917happen otherwise).
5918
5919On the Alpha, glibc declares st_flags although it isn't actually used;
5920the configure script was improved to detect this case so that
5921e2fsprogs can avoid using the non-functional stat field.
5922
5923The manual pages were updated to use a more consistent formatting
5924style consistent with standard Unix man pages.  Mke2fs's man page
5925added documentation for a few previously undocumented options.
5926
5927Fixed minor display bugs in tune2fs and mke2fs.
5928
5929Programmer's notes:
5930-------------------
5931
5932Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5933
5934Added features to parse and print feature strings into the e2p library.  
5935(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5936
5937ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5938whose directory entries contain proper filetype information if the
5939filesystem supports it.
5940
5941ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5942the directory entry filetype information.  This is used to set the
5943directory entry filetype information if the filesystem supports it.
5944
5945Fixed a bug in ext2fs_expand_dir() where the block count in a
5946directory's inode would not be properly incremented when the directory
5947was expanded to the point where an indirect block needed to be
5948allocated.
5949
5950
5951E2fsprogs 1.15 (July 18, 1999)
5952==============================
5953
5954Add configuration checks so that e2fsprogs will compile cleanly on
5955Linux 2.3 kernels that have renamed i_version to i_generation.
5956
5957E2fsck now prints a progress/completion bar (and not just a simple
5958spinner) if the -C0 option is requested or if it receives a SIGUSR1
5959signal.  Fsck will automatically manage the (potentially muliple)
5960e2fsck processes to print completion bars if it is given a -C option,
5961with the right thing happening if multiple filesystems are being
5962checked in parallel.
5963
5964Mke2fs now has better automatic hueristics to determine the filesystem
5965parameters to be used for a particular filesystem.  Added a new option
5966-T which allows the user to specify how the filesystem is to be used,
5967which helps mke2fs do a better job selecting the filesystem parameters.
5968
5969Mke2fs now creates revision 1 filesystems by default, and with the
5970sparse superblock feature enabled.  The sparse superblock feature is
5971not understood by Linux 2.0 kernels, so they will only allow read-only
5972mounts of filesystems with this sparse superblocks.
5973
5974Fix bug where if /dev/null couldn't be opened (should never happen),
5975e2fsck would hang in a tight loop.
5976
5977Make e2fsck handle the case where /lost+found isn't a directory.
5978
5979E2fsck now uses mallinfo if it exists to get accurate statistics about
5980its memory usage.
5981
5982Fix bug in e2fsck where it wouldn't check to see if a disconnected
5983inode had any problems before connecting it to /lost+found.
5984
5985Add check to e2fsck so it makes sure that total number of inodes in
5986the filesystem is a sane number.
5987
5988Fix fencepost error when clearing an the end of the block bitmap which
5989caused the last block in the bitmap not to get cleared.
5990
5991Cleaned up a number of messages in e2fsck:
5992	* The message "Group's #'s copy of the group descriptor..."
5993		was fixed so that the correct number would be displayed.
5994	* Added missing space in the "disk write-protected" error messsage
5995	* Cleaned up the error message printed when a non-interactive
5996		e2fsck needs to abort a check because the filesystem
5997		appears to be mounted.
5998
5999Added a new command-line utility, uuidgen, which will create and print
6000a UUID.
6001
6002Make debugfs's icheck command more robust by checking to make sure an
6003inode has valid blocks before interarting over the inode's blocks.
6004
6005UUID generation now uses a random-based scheme whenever possible to
6006prevent potential privacy problems.
6007
6008Man pages for all of the UUID functions in the lirbary were added.
6009
6010Fixed bug in fsck so it won't coredump if a filesystem not in
6011/etc/fstab is given to it.
6012
6013Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6014that most of the other mount utilities understands.
6015
6016Mke2fs will make a filesystem even if it appears mounted if the force
6017option is given.
6018
6019Dumpe2fs has new command-line options which allow a filesystem expert
6020to specify the superblock and blocksize when opening a filesystem.
6021This is mainly useful when examining the remains of a toasted
6022filesystem.
6023
6024The badblocks program has been updated to display correctly on disks
6025with large block numbers.
6026
6027The badblocks program no longer gives spurious errors when errors
6028occur on non-block boundaries, which is common if the blocksize is
6029larger than 1k.
6030
6031Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6032MKE2FS_SYNC environment variable is set.  This is to work around a VM
6033bug in the 2.0 kernel.  I've heard a report that a RAID user was able
6034to trigger it even using a 2.2 kernel, but hopefully it will not be
6035needed for most Linux 2.2 users.
6036
6037Fixed miscellaneous documentation and man pages.
6038
6039Programmer's notes:
6040-------------------
6041
6042Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6043in e2fsck's pass1.c really should have been static.
6044
6045The return value of the uuid_compare() function was changed to make it
6046match with the convetions used by strcmp, memcmp, and Paul Leach's
6047UUID sample document.
6048
6049The "make depend" process has now been made more automated; it now
6050automatically word-wraps the dependencies, and only replaces source
6051Makefile.in if there has been a change in the dependencies.  Also, a
6052top-level "make depend" now recurses through all the subdirectories
6053automatically.
6054
6055The Makefile in .../util has been changed so that subst is built using
6056the native C compiler during a cross-compilation, since the subst
6057program is only used during the build process.  Also add an explicit
6058rule to build util/subst by cd'ing to the correct directory and
6059running Makefile.
6060
6061The man directories are defined in terms mandir, so that the configure
6062script can override the location of the manual pages.
6063
6064The config files have been updated to recognize new machine types for
6065both the i386 and alpha families.
6066
6067Fsck has been modified so that it will accurately create an
6068fsck_instance even when the noexecute flag is set.  This allows for
6069accurate debugging of the fsck pass structure.  Also, when the verbose
6070flag is given twice, fsck will print debugging information about when
6071fsck is waiting for jobs to finish.
6072
6073
6074E2fsprogs 1.14 (January 9, 1999)
6075================================
6076
6077Fix the fstab parsing code so that it can handle blank lines and
6078comment characters.  Also, missing pass numbers need to be treated as
6079zero.
6080
6081Fixed a bug in e2fsck where under some circumstances (when e2fsck
6082needs to restart processing after fixing an egregious inconsistency)
6083it would try to access already freed memory.
6084
6085E2fsck now prints non-printable characters in directory entries and
6086pathnames using '^' and 'M-' notation.
6087
6088Fixed chattr so that it will ignore symbolic links when doing
6089recursive descent traversals.  For both chattr and lsattr, no longer
6090print the version string unless the -V option is given.
6091
6092Allow the system administrator to directly specify the number of
6093inodes desired in the filesystem, for some special cases where this is
6094necessary.
6095
6096Fix portability problems so that e2fsprogs can be compiled under Linux
60971.2 systems and Solaris systems.
6098
6099Update the config.guess file with a more recent version that will
6100identify newer Linux platforms.
6101
6102Programmer's notes
6103------------------
6104
6105Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6106an inode number of zero is passed to them.
6107
6108E2fsprogs 1.13 (December 15, 1998)
6109==================================
6110
6111Fixed a bug in debugfs where an error messages weren't getting printed
6112when the ext2 library routines to read inodes returned errors in the
6113stat, cmri and rm commands.
6114
6115Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6116provided, it won't create an inode table smaller than the minimum
6117number of inodes required for a proper ext2 filesystem.
6118
6119Fsck now parses the /etc/fstab file directly (instead of using
6120getmntent()), so that it can distinguish between a missing pass number
6121field and pass number field of zero.  This caused problems for
6122diskless workstations where all of the filesystems in /etc/fstab have
6123an explicit pass number of zero, and fsck could not distinguish this
6124from a /etc/fstab file with missing pass numbers.
6125
6126E2fsck will create a /lost+found directory if there isn't one in the
6127filesystem, since it's safer to create the lost+found directory before
6128it's needed.
6129
6130Fixed e2fsck so that it would detect bogus immutable inodes which
6131happen to be sockets and FIFO files, and offer to clear them.
6132
6133If a filesystem has multiple reasons why it needs to be checked, and
6134one of the reasons is that it is uncleanly mounted, e2fsck will print
6135that as the reason why the filesystem is being checked.
6136
6137Cleaned up the output routines of mke2fs so that it doesn't overflow
6138an 80 column display when formating really big filesystems.
6139
6140Added a sanity check to e2fsck to make sure that file descriptors 0,
61411, 2 are open before opening the hard disk.  This avoids a problem
6142where a broken program might exec e2fsck with those file descriptors
6143closed, which would cause disastrous results if the kernel returns a
6144file descriptor for the block device which is also used by FILE *
6145stdout.
6146
6147Fixed up the e2fsck progress reporting functions so that the values
6148reliably reach 100% at the completion of all of the e2fsck passes.
6149
6150Fixed minor documentation bugs in man pages and usage messages.
6151
6152Programmer's notes:
6153-------------------
6154
6155Fixed a number of lint warnings in the ext2fs library and potential
6156portability problems from other OS's header files that might define
6157CPP macros for names like "max" and "min".
6158
6159ext2fs_badblocks_list_add() has been made more efficient when it needs
6160to grow the bad blocks list.
6161
6162Fixed a bug in e2fsck which caused it to dereference a freed pointer
6163just before exiting.
6164
6165Fixed the substition process for generating the mk_cmds and compile_et
6166scripts so that they will work outside of the build tree.
6167
6168Add sanity check to e2fsck so that if an internal routine
6169(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6170and causing a core dump.  This should never happen, but...
6171
6172E2fsprogs 1.12 (July 9, 1998)
6173==================================
6174
6175E2fsprogs now works with glibc (at least with the version shipped wtih
6176RedHat 5.0).  The ext2fs_llseek() function should now work even with
6177i386 ELF shared libraries and if llseek() is not present.  We also
6178explicitly do a configure test to see if (a) llseek is in libc, and
6179(b) if llseek is declared in the system header files.  (See standard
6180complaints about libc developers don't understand the concept of
6181compatibility with previous versions of libc.)
6182
6183The ext2fs library now writes out the block group number in each of
6184the superblock copies.  This makes it easier to automatically
6185determine the starting block group of the filesystem when the block
6186group information is trashed.
6187
6188Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6189which means that e2fsprogs will ignore the high 8 bits of the
6190directory entry's name_len field, so that it can be used for other
6191purposes.
6192
6193Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6194E2fsprogs will now support filesystems with 64-bit sized files.
6195
6196Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6197
6198Added new program "e2label", contributed by Andries Brouwer.  E2label
6199provides an easy-to-use interface to modify the filesystem label.
6200
6201Fixed bug so that lsattr -v works instead of producing a core dump.
6202
6203Fixed a minor bug in mke2fs so that all groups with bad superblock
6204backup blocks are printed (not just the first one).
6205
6206Mke2fs will check the size of the device, and if the user specifies a
6207filesystem size larger than the apparent size of the device it will
6208print a warning message and ask if the user wants to proceed.
6209
6210E2fsck has a new option -C, which sends completion information to the
6211specified file descriptor.  For the most part, this is intended for
6212programs to use, although -C 0 will print a spinning character to the
6213stdout device, which may be useful for users who want to see something
6214happening while e2fsck goes about its business.
6215
6216Fixed a bug in e2fsck which could cause a core dump when it needs to
6217expand the /lost+found directory, and sometimes the bitmaps haven't
6218been merged in.  Also fixed a related bug where ext2fs_write_dir_block
6219was used to write out a non-directory block.  (Which would be bad on a
6220non-Intel platform with byte swapping going on.)
6221
6222Fixed bug in e2fsck where it would print a "programming error" message
6223instead of correctly identifying where a bad block was in used when
6224the bad block was in a non-primary superblock or block group
6225descriptor.  Also fixed a related bug when sparse superblocks are in
6226use and there is a bad block where a superblock or block group
6227descriptor would have been in a group that doesn't include a
6228superblock.
6229
6230Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6231the block group descriptor table is corrupt, it was possible to try to
6232allocate a huge array, fail, and then abort e2fsck.
6233ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6234and subsitutes reasonable values if the descriptors are obviously bogus.
6235
6236If e2fsck finds a device file which has the immutable flag set and the
6237i_blocks beyond the normal device number are non-zero, e2fsck will
6238offer to remove it, since it's probably caused by garbage in the inode
6239table.
6240
6241When opening a filesystem, e2fsck specially checks for the EROFS error
6242code, and prints a specific error message to the user which is more
6243user friendly.
6244
6245If the filesystem revision is too high, change the e2fsck to print
6246that this is either because e2fsck is out of date, or because the
6247superblock is corrupt.  
6248
6249E2fsck now checks for directories that have duplicate '.' and '..'
6250entries, and fixes this corruption.
6251
6252E2fsck no longer forces a sync of the filesystem (with attendant sleep
6253calls) at all times.  The ext2fs_flush() function now performs a sync
6254only if it needed to write data blocks to disk.
6255
6256Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6257certain errors would not be properly reported.
6258
6259Updated and expanded a few points in the man pages which users
6260complained wheren't explicit enough.
6261
6262Added special case byte-swapping code if compiling on the PowerPC, to
6263accomodate the strange big-endian variant of the ext2 filesystem that
6264was previously used on the PowerPC port.
6265
6266
6267Programmer's notes:
6268-------------------
6269
6270Removed C++ keywords from the ext2fs libraries so that it could be
6271compiled with C++.
6272
6273E2fsck's internal organization has now been massively reorganized so
6274that pass*.c don't have any printf statements.  Instead, all problems
6275are reported through the fix_problem() abstraction interface.  E2fsck
6276has also been revamped so that it can be called as a library from a
6277application.
6278
6279Added new fileio primitives in libext2fs for reading and writing
6280files on an unmounted ext2 filesystem.  This interface is now used by
6281debugfs.
6282
6283Added a new libext2fs function for mapping logical block numbers of
6284a file to a physical block number.
6285
6286Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6287a block, zeros it, and updates the filesystem accounting records
6288appropriately.
6289
6290Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6291sets the padding of the bitmap to be all one's.  Used by e2fsck pass 5.
6292
6293The libext2fs functions now use a set of memory allocation wrapper
6294functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6295instead of malloc, free, and resize.  This makes it easier for us to
6296be ported to strange environments where malloc, et. al. aren't
6297necessarily available.
6298
6299Change the libext2fs fucntion to return ext2-specific error codes
6300(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6301and depending on the existence of system error codes (such as EEXIST
6302and ENOENT).
6303
6304Renamed io.h to ext2_io.h to avoid collision with other OS's header
6305files.
6306
6307Add protection against ext2_io.h and ext2fs.h being included multiple
6308times.
6309
6310The types used for memory lengths, etc. have been made more portable.
6311In generla, the code has been made 16-bit safe.  Added Mark
6312Habersack's contributed DOS disk i/o routines.
6313
6314Miscellaneous portability fixes, including not depending on char's
6315being signed.
6316
6317The io_channel structure has a new element, app_data, which is
6318initialized by the ext2fs routines to contain a copy of the filesystem
6319handle.
6320
6321ext2fs_check_directory()'s callback function may now return the error
6322EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6323really do the checking, despite the presence of the callback function.
6324
6325
6326E2fsprosg 1.11 (June 17, 1997)
6327==============================
6328
6329Fixed e2fsck to detect (previously ignored) conflicts between the
6330superblock or block group descriptors and block bitmaps, inode
6331bitmaps, and inode tables.
6332
6333Fixed bug in e2fsck so that when the message printed out when a block
6334or inode bitmap conflicts with other data, it has the correct group
6335number.
6336
6337Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6338to badblocks.  This meant that not all of the filesystem was being
6339tested for bad blocks! 
6340
6341Fixed an array boundary overrun case which cropped up in
6342ext2fs_badblocks_list_test when a user tried running "mke2fs -c 
6343-b 4096".
6344
6345Adjusted the number of columns printed by mke2fs when displaying the
6346superblock backups to avoid running over 80 columns when making a
6347really big filesystem.
6348
6349Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6350dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6351fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6352
6353Programmer's notes:
6354-------------------
6355
6356Fixed install rule in lib/ss so that ss_err.h is actually getting
6357installed.
6358
6359Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6360bassed back to the caller.
6361
6362Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6363setting the current inode number (which meant this function wasn't
6364working at all).
6365
6366Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6367blocks in the bitmap when increasing the size of the bitmap.
6368
6369Changed the initial number of blocks allocated by ext2fs_init_dblist()
6370to be more realistic.
6371
6372Added a new function ext2fs_allocate_group_table, which sets up the
6373group descriptor information (and allocates inode and block bitmaps,
6374and inode tables for a particular group).  The function was created by
6375factoring out code form ext2fs_allocate_tables().
6376
6377Added a new function ext2fs_move_blocks which takes a bitmap of the
6378blocks to be moved, and moves them to another location on the
6379boardboard.
6380
6381Make the unix_io channel's io_channel_flush implementation calls sync()
6382to to flush the kernel buffers to disk.
6383
6384Added a new function ext2fs_dblist_count returns the number of
6385directory blocks in dblist.
6386
6387
6388E2fsprogs 1.10 (April 24, 1997)
6389===============================
6390
6391Mke2fs once again defaults to creating revision #0 filesystems, since
6392people were complaining about breaking compatibility with 1.2 kernels.
6393Warning messages were added to the mke2fs and tune2fs man pages that
6394the sparse superblock option isn't supported by most kernels yet (1.2
6395and 2.0 both don't support parse superblocks.)
6396
6397Added new flag to mke2fs, -R <raid options>, which allows the user to
6398tell mke2fs about the RAID configuration of the filesystem.  Currently
6399the only supported raid option is "stride" which specifies the width
6400of the RAID stripe.
6401
6402Fixed bug in e2fsck where pass1b would bomb out if there were any
6403blocks marked bad in the inode table.
6404
6405Fixed rare bug in mke2fs where if the user had a very unlucky number
6406of blocks in a filesystem (probability less than .002) the resulting
6407filesystem would be corrupt in the last block group.
6408
6409Fixed bug where if e2fsck tried to allocate a block to fix a
6410filesystem corruption problem and the filesystem had no free blocks,
6411ext2fs_new_block() would loop forever.
6412
6413The configure script now checks explicitly to see if "-static" works,
6414since that can't be assumed to be true --- RedHat doesn't install
6415libc-static by default.
6416
6417Fixed bug in libext2's block iterator functions where under some
6418cirmcustances, file with holes would cause the bcount parameter to the
6419callback function to be incorrect.  This bug didn't affect any of
6420e2fsprogs programs, but it was discovered by Paul Mackerras, the
6421author of the PPC boot loader.
6422
6423Removed use of static variables to store the inode cache in libext2fs.
6424This caused problems if more than one filesystem was accessed via
6425libext2fs (static variables in libraries are generally a bad idea).
6426Again, this didn't affect e2fsprogs programs, but it was discovered by
6427Paul Mackerras.
6428
6429Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6430will compile cleanly with 1.2.13 kernels (even with a.out shared
6431libraries!)
6432
6433Programmer's notes:
6434-------------------
6435
6436Added new functions to duplicate an ext2 filesystem handle, and its
6437associated substructure.  New functions: ext2fs_dup_handle(),
6438ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6439Other structures, such as the io_channel and the inode_cache, now have
6440a ref count so that they only get freed when they are no longer used
6441by any filesystem handle.  (These functions were added as part of the
6442development effort for an ext2 resizer).
6443
6444E2fsprogs 1.09 (April 14, 1997)
6445===============================
6446
6447Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6448accidentally introduced in the 1.08 release.  The overhead calculation
6449was accidentally removed, which caused ext2fs_initialize() to not
6450notice when the filesystem size needed to be adjusted down because
6451there wasn't enough space in the last block group.
6452
6453Fixed bug in version parsing library routine; it was always parsing
6454the library version string, instead of using the passed-in string.
6455
6456Clarified chattr man page.
6457
6458E2fsprogs 1.08 (April 10, 1997)
6459===============================
6460
6461E2fsck 1.07 was very slow when checking very large filesystems with a
6462lot of files that had hard links (i.e., news spools).  This was fixed
6463by seriously revamping the icount abstraction.  Added a formal test
6464suite for the icount abstraction.
6465
6466Debugfs now has a "-l" option to the "ls" command, which lists the
6467inode number, permissions, owner, group, size, and name of the files
6468in the directory.
6469
6470Fix a bug in e2fsck where when a directory had its blocks moved to
6471another location during the pass 1b processing, the directory block
6472list wasn't updated, so pass 2 wouldn't check (and correct) the
6473correct directory block.
6474
6475E2fsck will now treat inodes which contain blocks which are claimed by
6476the filesystem metadata by treating them as multiply claimed blocks.
6477This way, the data in those blocks can be copied to a new block during
6478the pass 1b--1d processing.
6479
6480E2fsck will attempt to determine the correct superblock number and
6481display it in the diagnostic and warning messages if possible.
6482
6483Add support for a new (incompatible) feature, "sparse_super".  This
6484feature reduces the number of blocks which contain copies of backup
6485superblocks and block group descriptors.  (It is only an incompatible
6486feature because of a bug in ext2_free_blocks.)  mke2fs and tune2fs now
6487support a new -s option; e2fsck will recognize filesystems built with
6488this feature turned on.
6489
6490E2fsck now checks the library to make sure is the correct version,
6491using new library functions.  (This helps to diagnose incorrectly
6492installed e2fsprogs distributions.)
6493
6494Dumpe2fs now prints more information; its now prints the the
6495filesystem revision number, the filesystem sparse_super feature (if
6496present), the block ranges for each block group, and the offset from
6497the beginning of the block group.
6498
6499Mke2fs now distributes the inode and block bitmap blok so that the
6500won't be concentrated in one or two disks in RAID/striping setups.
6501Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6502choose the largest blocks per group that be chosen.  (For 2k blocks,
6503you can have up to 16384 blocks/group; for 4k blocks, you can have up
6504to 32768 blocks/group.)  Previously mke2fs would not allow
6505specification of more than 8192 blocks per group, even if you were
6506using a 2k or 4k block group.
6507
6508Programmer's notes:
6509-------------------
6510
6511Added a new function ext2fs_create_icount2() which takes a "hint"
6512argument.  This hint argument presets the icount array with the list
6513of inodes which actually need to be in the icount array.  This really
6514helps to speed up e2fsck.
6515
6516Added a new function ext2fs_icount_validate() which checks the rep
6517invariant for the icount structure.  This is used mostly for testing.
6518
6519The error mesasage given when a bad inode number is passed to
6520test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6521EXT2FS_UNMARK_ERROR).
6522
6523Added a new function ext2fs_set_dir_block which sets the block of a
6524dblist entry, given the directory inode and blockcnt.
6525
6526Added a new function ext2fs_get_library_version() which returns the
6527current library version, and ext2fs_parse_version_string() which
6528returns a version number based on a e2fsprogs version string.
6529
6530The icount functions will return EINVAL if the passed in inode number
6531is out of bounds.
6532
6533E2fsprogs 1.07 (March 9, 1997)
6534==============================
6535
6536E2fsck is now uses much less memory when checking really large
6537filesystems (or rather, filesystems with a large number of inodes).
6538Previously a filesystem with 1 million inodes required 4 megabytes of
6539memory to store inode count statistics; that storage requirement has
6540now been reduced to roughly half a megabyte.
6541
6542E2fsck can now properly deal with bad blocks appearing inside the
6543inode table.  Instead of trying to relocate the inode table (which
6544often failed because there wasn't enough space), the inodes in the bad
6545block are marked as in use.
6546
6547E2fsck will automatically try to use the backup superblocks if the
6548primary superblocks have a bad magic number or have missing meta-data
6549blocks (or meta-data blocks which are out of range).
6550
6551E2fsck's pass 3 has been made more efficient; most noticeable on
6552filesystems with a very large number of directories.
6553
6554Completely revamped e2fsck's system of printing problem reports.  It
6555is now table driven, to make them more easily customizeable and
6556extendable.  Error messages which can be printed out during preen mode
6557are now one line long.
6558
6559Fixed e2fsck's filesystem swapping code so that it won't try to swap
6560fast symbolic links or deleted files.
6561
6562Fixed e2fsck core dumping when fixing a filesystem which has no
6563directories (not even a root directory).
6564
6565Added a check to e2fsck to make sure that the length of every
6566directory entry is a multiple of 4 (since the kernel complains if it
6567isn't).
6568
6569Added a check to e2fsck to make sure that a directory entry isn't a
6570link to the root directory, since that isn't allowed.
6571
6572Added a check to e2fsk to now make sure the '.' and '..' directory
6573entries are null terminated, since the 2.0 kernel requires it.
6574
6575Added check to write_bitmaps() to make sure the superblock doesn't get
6576trashed if the inode or block bitmap is marked as being block zero.
6577
6578Added checking of the new feature set fields in the superblock, to
6579avoid dealing with new filesystem features that this package wasn't
6580set up to handle.
6581
6582Fixed a fencepost error in ext2fs_new_block() which would occasionally
6583try to allocate a block beyond the end of a filesystem.
6584
6585When the UUID library picks a random IEEE 802 address (because it
6586can't find one from a network card), it sets the multicast bit, to
6587avoid conflicting with a legitimate IEEE 802 address.
6588
6589Mke2fs now sets the root directory's owner to be the real uid of the
6590user running mke2fs.  If the real uid is non-zero, it also sets
6591the group ownership of the root directory to be the real group-id of
6592the user running mke2fs.
6593
6594Mke2fs now has more intelligent error checking when it is given a
6595non-existent device.
6596
6597When badblocks is given the -vv option, it now updates the block that
6598it is currently testing on every block.
6599
6600Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6601currently correctly if PATH wasn't already set.
6602
6603Shared libraries now built with dependencies.  This allows the shared
6604library files to be used with dlopen(); it also makes the transition
6605to libc 6 easier, since ld.so can tell which libc a particular shared
6606library expects to use.
6607
6608Programmer's notes:
6609-------------------
6610
6611Added new abstraction (defined in dblist.c) for maintaining a list of
6612blocks which belongs to directories.  This is used in e2fsck and other
6613programs which need to iterate over all directories.
6614
6615Added new functions which test to see if a contiguous range of blocks
6616(or inodes) are available.  (ext2fs_*_bitmap_range).
6617
6618Added new function (ext2_inode_has_valid_blocks) which returns true if
6619an inode has valid blocks.  (moved from e2fsck code).
6620
6621Added new function (ext2fs_allocate_tables) which allocates the
6622meta-data blocks as part of initializing a filesystem.  (moved from
6623mke2fs code).
6624
6625Added a new I/O manager for testing purposes.  It will either allow a
6626program to intercept I/O requests, or print debugging messages to
6627trace the activity of a program using the I/O manager.
6628
6629The badblocks_list functions now store the bad blocks in a sorted
6630order, and use a binary search to speed up badblocks_list_test.
6631
6632The inode scan function ext2fs_get_next_inode() may now return a soft
6633error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6634those cases where part of an inode table is missing or there is a bad
6635block in the inode table.  
6636
6637Added a new function (ext2fs_block_iterate2) which adds new arguments to
6638the callback function to return a pointer (block and offset) to the
6639reference of the block.
6640
6641Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6642application to jump to a particular block group while doing an inode
6643scan.
6644
6645The badblocks list functions were renamed from badblocks_* to
6646ext2fs_badblocks_*.  Backwards compatibility functions are available
6647for now, but programs should be modified to use the new interface.
6648
6649Some of the library functions were reorganized into separate files to
6650reduce the size of some programs which statically link against the
6651ext2 library.
6652
6653Put in some miscellaneous fixes for the Alpha platform.
6654
6655
6656E2fsprogs 1.06 (October 7, 1996)
6657================================
6658
6659Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6660smash the backup copies in ext2fs_close().  (The problem was that when
6661e2fsck -p discovered the problem, while it was closing the filesystem
6662and exiting, it was also blowing away the backup superblocks on the
6663disk, which was less than friendly.)  We now make it the case that we
6664only write out the backup superblock and the back block descriptors if
6665the filesystem is completely free from problems.
6666
6667Fixed a bug in block_interate in the lib/ext2fs library which caused
6668e2fsck to fail on GNU Hurd-created filesystems.
6669
6670Add support for Linux/FT's bootloader, which actually uses
6671EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6672to clear the inode.
6673
6674Add support for the "A" (no atime update) attribute.  (Note: this
6675attribute is not yet in production kernels.)
6676
6677The test suite is not automatically run when doing a "make all" from
6678the top level directory.  Users should manually run "make check" if
6679they wish to run the test suite.
6680
6681Upon a preenhalt(), make the printed message more explicit that
6682running e2fsck "MANAULLY" means without the -p or -a options.
6683
6684In e2fsck, if a disconnected inode is zero-length, offer to clear it
6685instead of offering to connect it to lost+found.
6686
6687In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6688e2fsck to be run over it, change e2fsck to explicitly display this
6689fact.
6690
6691For dumpe2fs and e2fsck, cause the -V option to print out which
6692version of the ext2fs library is actually getting used.  (This will
6693help detect mismatches of using a 1.06 utility with a 1.05 library,
6694etc.)
6695
6696Programmers' notes:
6697-------------------
6698
6699EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6700the naming convention.
6701
6702In ext2fs_initialize(), make sure the description for the inode bitmap
6703is correctly initialize.
6704
6705Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6706
6707E2fsprogs 1.05 (September 7, 1996)
6708==================================
6709
6710Add support for new fields in the ext2 superblock --- volume name,
6711volume UUID, and last mounted field.  Dumpe2fs displays these fields,
6712tune2fs and mke2fs allows you to set them.  E2fsck will automatically
6713generate a UUID for those volumes that don't have them.  
6714
6715Put in support for e2fsck to recognize HURD specific ext2 features ---
6716most notably, the translator block.  The e2fsprogs tools will now use
6717the creator_os field in the superblock to correctly handle different
6718OS-specific variants of the ext2 filesystem.
6719
6720E2fsck now fixes inodes which have a the deletion time set, but which
6721have a non-zero i_link_count field by offering to clear the deletion
6722time.  Previously e2fsck assumed that the inode was deleted (per 0.3c
6723ext2 kernel behavior) and offered to unlink the file.
6724
6725If e2fsck sets the clean bit, but nothing else, set the exit code
6726FSCK_NONDESTRUCT.  After all, e2fsck did fix a filesystem error --- it
6727set the filesystem valid bit when it was previously cleared.  :-) This
6728was needed to make the HURD fsck driver happy.
6729
6730If the  user  refuses to attach an  unattached  inode, e2fsck  will no
6731longer set the inode's link count.  Otherwise, the  inode would end up
6732getting marked as unused, which might cause loss of data later.
6733
6734Make the message issued by e2fsck when the superblock is corrupt less
6735confusing for users.  It now mentions that another reason for the
6736"corrupt superblock" message might be that the partition might not be
6737an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6738
6739Make the libext2 library more robuest so that e2fsck won't coredump on
6740an illegal superblock where the blocksize is zero.  (f_crashdisk is
6741the test case).
6742
6743By default, create filesystems where the default checkinterval is 6
6744months (180 days).  Linux servers can be robust enough that 20 reboots
6745can be a long, long time.
6746
6747Added configure flag --enable-old-bitops, which forces the bitops to
6748use the old (native) bitmask operations.  By default on the sparc
6749platform, the standard ext2 bit ordering is now used.
6750
6751Added a new feature to e2fsck to byte-swap filesystems; this can be
6752used to convert old m68k filesystems to use the standard byte-order
6753storage for the superblock, inodes, and directory blocks.  This
6754function is invoked by using the '-s' option to e2fsck.
6755
6756Debugfs's "dump" command has been enhanced so that it writes out the
6757exact size of the file so that the nulls at the end of the file are
6758eliminated.  The command also accept a new "-p" option which will
6759attempt preserve to preserve the ownernship, permissions, and
6760file modification/access times.
6761
6762Debugfs has two new options, -f and -R.  The -R option allows the user
6763to execute a single debugfs command from the command line.  The -f
6764option allows the user to specify a "command file" containing debugfs
6765commands which will get executed.
6766
6767Dumpe2fs now pretty prints the check interval, instead of just
6768printing the check interval as a number of seconds.
6769
6770Fix bugs in debugfs: the params command when no filesystem is opened
6771no longer causes a core dump.  It is now possible to unlink a file
6772when a pathame containing a '/' is specified.
6773
6774Tune2fs has a new -C option which sets the number of times the
6775filesystem has been mounted.
6776
6777Fix the chattr '-v' option so that it actually works.  Chattr was
6778being buggy about the -v option parsing.
6779
6780Programmers' notes:
6781-------------------
6782
6783The directory lib/uuid contains a set of library routines to generate
6784DCE compatible UUIDs.  
6785
6786Extended ext2fs_namei() to handle symbolic links.  Added new function
6787ext2fs_nami_follow() which will follow last symbolic link in the case
6788where the pathname points to a sym link.
6789
6790The ext2fs_block_iterate function will now return the HURD translator
6791block, if present.  The new flag BLOCK_FLAG_DATA_ONLY will cause the
6792iterator to return data blocks only.  The ext2fs.h file now defines
6793constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6794BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6795count field of the iterator callback function.
6796
6797The test script driver now takes an optional second argument, which is
6798the test case to be run.  This allows you to run a test case without
6799needing to run the entire test suite.
6800
6801On Linux ELF systems, install the .so files in the correct places
6802(/usr/lib).  The .so files must be stored in the same directory as the
6803.a files.
6804
6805Fixed miscellaneous HURD compilation issues with header file being
6806included in the right order.
6807
6808Fixed debugfs so that it resets optind to zero, not one, since setting
6809optind to zero is more correct.
6810

6812E2fsprogs 1.04 (May 16, 1996)
6813=============================
6814
6815First "official" (1.03 was a limited release only) to support building
6816e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6817kernels).
6818
6819This package includes a RPM specs file, that it can be built using the
6820RedHat Package Manager.
6821
6822E2fsck now prints a hint that if there are lots of incorrectly located
6823inode bitmaps, block bitmaps, and inode table blocks, the user might
6824want to try using e2fsck -b 8193 first, to see if that fares any
6825better.
6826
6827For ext2 filesystem written with the hurd, debugfs will now print out
6828the translator field when printing an inode structure.
6829
6830Lots of miscellaneous linking/installation cleanups:
6831
6832  Libraries are now linked using a relative pathname, instead of
6833  relying on -L working correct.  It doesn't, in many cases, including
6834  current versions of GNU ld.  This guarantees that the build tree is
6835  linking with the right libraries, instead of the ones installed in
6836  /usr/lib.
6837
6838  Header files, man pages, and the et/ss shell scripts are now
6839  generated using a custom substitution script, instead of relying on
6840  the configure script.  This prevents needless recompilation of
6841  files; in addition, the custom substitution script is much faster.
6842
6843  e2fsck may now be linked dynamically, by using the
6844  --enable-dynamic-e2fsck flag to configure.  This is not recommended,
6845  since it increases e2fsck's dependence on other files, but some
6846  people need to save disk space, and other critical programs on their
6847  systems were being linked dynamically anyway.
6848
6849  Programs such as fsck which didn't need to be linked against
6850  libext2fs (or mke2fs which didn't need to be linked against libe2p)
6851  only link against libraries they actually need.  Otherwise, those
6852  programs would require the presense of libraries that otherwise
6853  could be removed from a rescuse diskette.
6854
6855  The ss include files are now installed correctly so they can
6856  actually be used by another package.
6857
6858  If the profiling libraries are built, they are now installed on a
6859  "make install-libs".
6860
6861
6862E2fsprogs 1.03 (March 27, 1996)
6863===============================
6864
6865Change the m68k bit numbering for bitmasks to match the bit numbering
6866used by all other ext2 implementations.  (This change was requested by
6867the m68k kernel development team.)
6868
6869Support (in-development) filesystem format revision which supports
6870(among other things) dynamically sized inodes.
6871
6872Fixed a bug in the ext2 library so that an intelligent error is
6873returned if mke2fs is run with a ridiculously small number of blocks
6874for a partition.
6875
6876Fixed a bug in the ext2 library which required that the device be
6877openable in read/write mode in order to determine its size.  This
6878caused e2fsck -n to require read/write access when it was not
6879previously necessary.
6880
6881Fixed a bug in e2fsck which casued it to occasionally fail the test
6882suite depending on which version of the floating point library it was
6883using.
6884
6885Fixed a bug in e2fsck so that it now halts with a fatal error when
6886certain superblock consistency checks fail.  Previously it continued
6887running e2fsck, with some potential confusing/damaging consequences.
6888
6889Added new flag to fsck which allows the root to be checked in parallel
6890with other filesytems.  This is not the safest thing in the world to
6891do, but some system administrators really wanted it.
6892
6893Fixed -Wall flames in lib/ss.
6894
6895
6896E2fsprogs 1.02 (January 16, 1996)
6897=================================
6898
6899Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6900
6901Change e2fsck to print statistics of how many non-contiguous files are
6902on the system.  Note that a file which is larger than 8k blocks, it is
6903guaranteed to be non-contiguous.
6904
6905In mke2fs, print a warning message if a user tries to format a whole
6906disk (/dev/hda versus /dev/hda1).  If a user really wants to format a
6907whole disk, the -F (force) option forces mke2fs to format a whole disk
6908as a filesytem.
6909
6910Fix a bug in fsck where in some cases it might start checking
6911partitions in the next pass before it finishes checking partitions in
6912the current pass.  This still won't cause two partitions on the same
6913disk will be checked, so it's rarely a problem in real life.
6914
6915Patch lsattr so that it won't hang when checking a named pipe.
6916
6917Minor compilation fixes:
6918	* Fix the order of libraries that were linked in debugfs.
6919	* Allow the sources to be compiled with -ansi turned on.
