RELEASE-NOTES revision a6ce1349539f866334ef3d5758bc2ee44a454acd
1E2fsprogs 1.41.14 (December 22, 2010)
2=====================================
3
4Fix spurious complaint in mke2fs where it would complain if the file
5system type "default" is not defined in mke2fs.conf.
6
7The resize2fs program will no longer clear the resize_inode feature
8when the number reserved group descriptor blocks reaches zero.  This
9allows for subsequent shrinks of the file system to work cleanly for
10flex_bg file systems.
11
12The resize2fs program now handles devices which are exactly 16T;
13previously it would give an error saying that the file system was too
14big.
15
16E2fsck (and the libext2fs library) will not use the extended rec_len
17encoding for file systems whose block size is less than 64k, for
18consistency with the kernel.

20Programming notes
21-----------------
22
23E2fsprogs 1.41.13 would not compile on big-endian systems.  This has
24been fixed.  (Addresses Sourceforge Bug: #3138115)
25
26The ext2fs_block_iterator2() function passed an incorrect ref_offset
27to its callback function in the case of sparse files.  (Addresses
28Sourceforge Bug: #3081087)
29    
30Fix some type-punning warnings generated by newer versions of gcc.
31
32
33E2fsprogs 1.41.13 (December 13, 2010)
34=====================================
35
36E2fsck now supports the extended option "-E journal_only", which
37causes it to only do a journal replay.  This is useful for scripts
38that want to first replay the journal and then check to see if it
39contains errors.
40
41E2fsck will now support UUID= and LABEL= specifiers for the -j option
42(which specifies where to find the external journal).  (Addresses
43Debian Bug #559315)
44
45E2fsck now has support for the problems/<problem code>/force_no
46configuration option in e2fsck.conf, which forces a problem to not be
47fixed.
48
49Dumpe2fs will now avoid printing large negative offsets for the bitmap
50blocks and instead print a message which is a bit more helpful for
51flex_bg file systems.
52
53Mke2fs will now check the file system type (specified with the -t
54option) to make sure it is defined in the mke2fs.conf file; if it is
55not, it will print an error and abort.  If the usage type (specified
56with the -T option) is not defined in mke2fs.conf, mke2fs will print a
57warning but will continue.  (Addresses Debian Bug #594609)
58
59Clarified error message from resize2fs clarifying that on-line
60shrinking is not supported at all.  (Addresses Debian Bug #599786)
61    
62Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
63displayed.  (Addresses Debian Bug #555456)
64
65E2fsck will open the external journal in exclusive mode, to prevent
66the journal from getting truncated while it is in use due to a user
67accidentally trying to run e2fsck on a snapshotted file system volume.
68(Addresses Debian Bug #587531)
69
70Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
71flag.
72
73The tune2fs program can now set the uninit_bg feature without
74requiring an fsck.
75
76The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
77default mount options settings which were added in 2.6.35.
78
79The e2fsck and dumpe2fs programs now support the new ext4 superblock
80fields which track where and when the first and most recent file
81system errors occurred.  These fields are displayed by dumpe2fs and
82cleared by e2fsck.  These new superblock fields were added in 2.6.36.
83
84Debugfs now uses a more concicse format for listing extents in its
85stat command.  This format also includes the interior extent tree
86blocks, which previously was missing from stat's output for
87extent-based files.
88
89Debugfs has a new option, -D, which will request Direct I/O access of
90the file system.
91
92Mke2fs will skip initializing the inode table if a device supports
93discard and the discard operation will result in zero'ed blocks.
94
95Badblocks will now correctly backspace over UTF-8 characters when
96displaying its progress bar.  (Addresses Gentoo Bug #309909; Addresses
97Debian Bugs #583782 and #587834)
98
99E2freefrag will now display the total number of free extents.
100
101Resize2fs -P no longer requires a freshly checked filesystem before
102printing the minimum resize size.
103
104Fixed a floating point precision error in a binary tree search routine
105that can lead to seg fault in e2fsck and resize2fs.
106
107Fixed a bug in e2fsck where if both the original and backup superblock
108are invalid in some way, e2fsck will fail going back to the original
109superblock because it didn't close the backup superblock first, and
110the exclusive open prevented the file system from being reopened.
111
112Fixed a big in e2freefrag which caused getopt parsing to fail on
113architectures with unsigned chars.  (Addresses Gentoo Bug: #299386)
114
115Clarified an mke2fs error message so a missed common in an -E option
116(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
117results in a more understandable explanation to the user.
118
119Mke2fs now displays the correct valid inode ratio range when
120complaining about an invalid inode ratio specified by the user.
121
122Mke2fs now understands the extended option "discard" and "nodiscard",
123and the older option -K is deprecated.  The default of whether
124discards are enabled by default can be controled by the mke2fs.conf
125file.
126
127Mke2fs's handling of logical and physical sector sizes has been
128improved to reflect the fact that there will be some SSD's with 8k and
12916k physical sectors arriving soon.  Mke2fs will no longer force block
130size to be the physical sector size, since there will be devices where
131the physical sector size is larger than the system's page size, and
132hence larger than the maximal supported block size.  In addition, if
133the minimal and optimal io size are not exported by the device, and
134the physical sector size is larger than the block size, the physical
135sector size will be used to set the Raid I/O optimization hints in the
136superblock.
137
138E2fsck will now display a better, more specific error message when the
139user enters a typo'ed device name, instead of blathering on about
140alternate superblocks.
141
142Fixed various Debian Packaging Issues
143
144Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
145#589345, #591083; Addresses Launchpad Bug: #505719)
146
147Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
148Polish, Swedish, and Vietnamese translations.
149
150
151Programmer's Notes
152------------------
153
154Fix a dependency definition for the static and profiled blkid
155libraries which could cause compile failures in some configurations.
156(Addresses Debian Bug: #604629)
157    
158Add support for Direct I/O in the Unix I/O access layer.
159
160Fixed a memory leak in the Unix I/O layer when changing block sizes.
161
162Fixed minor memory leaks in mke2fs.
163
164Added a new function to the ext2fs library, ext2fs_get_memalign().
165
166The tst_super_size test program will check to make sure the superblock
167fields are correctly aligned and will print them out so they can be
168manually checked for correctness.
169
170Fixed some makefile dependencies for test programs in lib/ext2fs.
171
172Reserved the feature flags and superblock fields needed for the Next3
173snapshot feature.
174
175Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
176EXT4_INCOMPAT_EA_INODE.
177
178
179E2fsprogs 1.41.12 (May 17, 2010)
180================================
181
182Mke2fs now gives a correct error message if the external journal
183device is not found.  (Addresses Red Hat Bug #572935)
184
185Resize2fs -P will now refuse to print a minimum size if the file
186system is not clean.  Previously it would go ahead and print a minimum
187size anyway, which might not be correct, leading to user confusion.
188
189E2fsck now tests for extents that begin at physical block 0 and
190rejects them as invalid.  (Addresses Google Bug: #2573806)
191    
192Fixed a bug in e2fsck which could cause it to crash when trying to
193remove an invalid extent and the block bitmaps hadn't yet been loaded.
194(Addresses SourceForge Bug: #2971800)
195    
196E2fsck now will completely skip time-based checks if the system clock
197looks insane or the option broken_system_clock is set in
198/etc/e2fsck.conf.
199
200E2fsck would previously report an i_blocks corruption for a 4T file
201created using posix_fallocate; this bug has been fixed.
202
203E2fsck will now correctly mark a sparse journal as invalid and will
204delete and recreate the journal to address the problem.
205
206E2fsck would previously incorrectly ask the user whether she would
207like to abort the file system check after finding a problem --- and
208then abort regardless of the user's answer.  This is annoying, and
209has been fixed.
210
211E2fsck can now continue even if it fails to recreate the resize
212inode; previously it would just abort the file system check
213altogether.
214
215E2fsck could potentially remove directory entries for inodes found in
216the unused region of the inode table; this would generally happen on
217ext4 file systems that do not use journaling.  This bug has been fixed
218by not clearing these directory entries once it has been established
219that bg_unused_inodes may not be trustworthy; once pass #2 has been
220completed, e2fsck will restart the file system check from the
221beginning, and then it will be safe to delete any directory entries
222pointing to inodes that appear to be deleted.  (Addresses Google Bug:
223#2642165)
224    
225E2fsck will not try to set the block group checksums if the user
226cancels the fsck with a control-C.  It's a bad idea to set the
227checksums if e2fsck hasn't been completed, and it often results an the
228error message, "Inode bitmap not loaded while setting block group
229checksum info".  (Addresses Launchpad Bug: #582035)
230
231The mke2fs program now queries the kernel for the physical as well as
232the logical sector size, and will not allow a blocksize below the
233logical, and will strongly encourage a blocksize at least as big as
234the physical blocksize.  This is needed for 4k sector drives that
235emulate 512 byte sector sizes.
236
237Mke2fs will now allow a flex_bg size of 1.  This is unusual, and
238rarely needed, but it is a legal value.
239
240E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
241not needed, and offer to clear it; this is a sign of a kernel bug, but
242more importantly, some released kernels may crash when this situation
243is encountered on ext4 file systems.  (Addresses Google Bug: #2604224)
244    
245E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
246i_size is correct.  (Kernels starting with 2.6.34 will set
247EOFBLOCKS_FL.)
248
249The com_err library will now only output ^M (a CR character) when the
250tty is in raw mode.
251
252Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
253and Vietnamese translations.
254
255Fixed various Debian packaging issues --- see debian/changelog for
256details.  (Addresses Debian Bugs: #571247, #563487)
257
258
259Programmer's Notes
260------------------
261
262The regression test suite now uses its own mke2fs.conf file, so that
263downstream distributions want change the mke2fs.conf file which is
264distributed in the RPM or dpkg file, without worrying about screwing
265up the regression test results.
266
267Always build namei.o so that building with configure --disable-debugfs
268works correctly.  Long-term, if we care about reduced e2fsprogs
269builds, we need a more general solution for deciding what .o files are
270needed for a particular build.  Given that install floppies are going
271(gone?) the way the dodo bird, we probably don't care, though.
272(Addresses Sourceforge Bug: #2911433)
273
274Add configure options --enable-symlink-build and
275--enable-symlink-install, which allow e2fsprogs be built using
276symlinks instad of hard links, and to be installed using symlinks
277instead of hard links, respectively.  It is useful when the file
278system where the build is taking place, or the file system where
279e2fsprogs is installed, can't handle hard links for some reason.
280(Addresses Sourceforge Bug: #1436294)
281
282Fixed compile warning in mke2fs.c.
283
284    
285E2fsprogs 1.41.11 (March 14, 2010)
286==================================
287
288E2fsck will no longer give a fatal error and abort if the physical
289device has been resized beyond 2**32 blocks.  (Addresses Launchpad
290Bug: #521648)
291
292Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
293the allocation status of the block <blk>.  (Addresses Debian Bug:
294#564084)
295    
296E2fsck now prints a much more emphatic and hopefully scary message
297when a file system is detected as mounted while doing a read/write
298check of the filesystem.  Hopefully this will dissuade users from
299thinking, "surely that message doesn't apply to *me*" :-(
300
301E2fsck -n will now always open the file system read-only.  We now
302disallow certain combination of options which previously were manual
303exceptions; this is bad because it causes users to think they are
304smarter than they really are.  So "-n -c", "-n -l", "-n -L", and "-n
305-D" are no longer supported.  (Addresses Launchpad Bug: #537483)
306    
307In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
308it detected a badly aligned partition.  Unfortunately, this broke some
309distribution installation scripts, so it now just prints the warning
310message and proceeds.  (Addresses Red Hat Bug: #569021. Addresses
311Launchpad Bug: #530071)
312    
313Mke2fs would take a long time to create very large journal files for
314ext4.  This was caused by a bug in ext2fs_block_iterate2(), which is
315now fixed.
316
317E2fsck now understands the EOFBLOCKS_FL flag which will be used in
3182.6.34 kernels to make e2fsck not complain about blocks deliberately
319fallocated() beyond an inode's i_size.
320
321E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
322e2fsck -fD can corrupt non-indexed directories when are exists one or
323more file names which alphabetically sort before ".".  This can happen
324with ext2 filesystems or for small directories (take less than a lock)
325which contain filenames that begin with a space or some other
326punctuation mark.  (Addresses Debian Bug: #573923, Addresses Launchpad
327Bug: #525114)
328
329
330Programmer's Notes
331------------------
332
333Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
334correctly.
335
336The libcom_err function now has support for Heimdal's com_right_r
337function().  (Addresses Sourceforge Bug: #2963865, Addresses Debian
338Bug: #558910)
339
340
341E2fsprogs 1.41.10 (February 7, 2010)
342====================================
343
344Fix resize2fs bug which causes it to access invalid memory.
345
346Add libss support for libreadline.so.6.
347    
348Fix e2fsck's check for extent-mapped directory with an incorrect file
349type.
350
351Add new e2fsck.conf configuration option, default/broken_system_clock
352to support systems with broken CMOS hardware clocks.  Also, since too
353many distributions seem to have broken virtualization scripts now,
354e2fsck will by default accept dates which are off by up to 24 hours by
355default.  (Addresses Debian Bugs: #559776, #557636)
356
357Fix a bug where mke2fs may not use the best placement of the inode
358table when there is only room for a single block group in the last
359flex_bg.
360
361E2fsck is now smarter when it needs to allocate blocks in the course
362of fixing file system problems.  This reduces the number of spurious
363differences found in pass #5.
364
365E2fsck will no longer rehash directories which fit in a single
366directory block.
367
368E2fsck now correctly handles holes in extent-mapped directories (i.e.,
369sparse directories which use extents).
370
371Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
372
373Fix a bug in filefrag where on platforms which can allow file systems
374with 8k blocks, that it doesn't core dump when it sees a file system
375with 8k block sizes.  (Thanks to Mikulas Patocka for pointing this
376out.)
377
378E2fsck will correctly fix directories that are have an inaccurate
379i_size as well as other problems in a single pass, instead of
380requiring two e2fsck runs before the file system is fully fixed.
381
382Fix e2fsck so it will correctly find and detect duplicate directory
383entries for non-indexed directories.  ( Addresses Sourceforge Bug:
384#2862551)
385    
386Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
387thinly-provisioned storage device.  This can be disabled using the -K
388option.
389
390Enhance libext2fs so it works around bug in Linux version 2.6.19
391and earlier where the /proc/swaps file was missing the header on
392the first line.
393
394Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
395was missing the header on the first line.
396
397Fix some big-endian bugs in e2fsck and libext2fs.
398
399Fix resize2fs so it works correctly on file systems with external
400journals instead of failing early with the error "Illegal inode
401number".
402
403Fix libss so that it does not seg fault when using a readline library
404which does not supply a readline_shutdown() function.
405
406Updated dumpe2fs's usage message so it correctly gives the right
407arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
408(Addresses Launchpad Bug: #448099)
409   
410Teach libext2fs to ignore the high 32 bits of the i_blocks field
411when huge_file file system feature is set, but the inode does not
412have the HUGE_FILE_FL flag set.
413
414Fix e2fsck's handling of 64-bit i_blocks fields.
415
416E2fsck will now print "Illegal indirect block", "Illegal
417double-indirect block", etc., instead of "Illegal block #-1" or
418"Illegal block #-2", etc.  This makes it easier for users to
419understand what has gone wrong.  (Addresses SourceForge Bug: #2871782)
420
421Mke2fs now will obtain get device topology information from blkid and
422use it to populate the superblock stride and stripe sizes.  It will
423also warn if the block device is misaligned
424
425Fix file descriptor leaks in fsck and debugfs.  (Addresses Novell Bug:
426##524526)
427
428Fix the libext2fs library code to round up the bitmap size to a 4-byte
429boundary, to prevent spurious seg faults caused by the x86
430architecture.  This doesn't affect Linux systems, but was a major
431problem on a number of *BSD systems.  (Addresses Sourceforge Bug:
432#2328708)
433
434Fix resize2fs's minimum size required for a file system so it doesn't
435fail when "resize2fs -M" is run.  (Addresses RedHat Bugzilla: #519131)
436    
437Dumpe2fs now prints summary information about the contents of the
438journal.
439    
440Avoid printing scary error messages when e2fsck starts running
441problems on low-memory systems, as it tends to panic and mislead the
442user.  (Addresses Debian Bug: #509529)
443
444Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
445modules files.  (Address Red Hat Bug: #518572)
446    
447Fix tune2fs so it can add a journal when an extent-enabled file system
448is mounted.  (Addresses Launchpad bug: #416648)
449
450Update Czech, Indonesian, Polish and Vietnamese translations (from the
451Translation Project).
452    
453Update/clarify man pages.  (Addresses Sourceforge Bug: #2822186)
454
455Fixed various Debian packaging issues --- see debian/changelog for
456details.  (Addresses Debian Bugs: #540111)
457
458Programmer's Notes
459------------------
460
461The configure script supports the --with-cc, --with-ccopts, and
462--with-ldopts options.  Instead, the more standard use of CC=,
463CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
464Also, --with-ld, which never worked, was also removed.
465(Addresses Sourceforge Bug: #2843248)
466
467The in-tree header files are only used if the in-tree uuid or blkid
468libraries are used.  Otherwise, use the system-provided uuid or blkid
469header files if using the system-provided libraries.
470
471Fix some build failures caused by --disable-* configure options.
472
473Work around a bug in autoconf 2.64.
474
475
476E2fsprogs 1.41.9 (August 22, 2009)
477==================================
478
479Fix a bug in e2fsck routines for reallocating an inode table which
480could cause it to loop forever on an ext4 filesystem with the FLEX_BG
481filesystem feature with a relatively rare (and specific) filesystem
482corruption.  This fix causes e2fsck to try to find space for a new
483portion of the inode table in the containing flex_bg, and if that
484fails, the new portion of the inode table will be allocated in any
485free space available in the filesystem.
486
487Make e2fsck less annoying by only asking for permission to relocate a
488block group's inode table once, instead of for every overlapping
489block.  Similarly, only ask once to recompute the block group
490checksums, instead of once for each corrupted block group's checksum.
491
492Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
493not present, and it needs to fall back to using the FIBMAP ioctl.
494
495Fix filefrag to correctly print the number of extents for zero-length
496files.  (Addresses Debian Bug: #540376)
497
498Filefrag now has a -B option which forces the use of the FIBMAP ioctl
499to more easily debug the FIBMAP code.
500
501Fixed filefrag for non-extent based files.
502
503Add a new program, e2freefrag, which displays information about the
504free space fragmentation in an ext2/3/4 filesystem.
505
506Fix inode resizing via tune2fs -I so that it works correctly in the
507face of non-empty bad blocks inodes, and if the filesystem was
508formatted using the "mke2fs -E stride=N" option for RAID arrays.
509
510Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
511and corrupt large directories if the directory needs to shrink by more
512than one block.  (Addresses Debian Bug: #537510)
513    
514Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
515last mount times are in the future, they are corrected even if
516buggy_init_scripts is set.  This is needed because otherwise resize2fs
517will refuse to resize the filesystem, even after running "e2fsck -f".
518(Addresses Launchpad bug: #373409)
519
520E2fsck will now print much fuller information when the last mount time
521or last written time is in the future, since most people can't seem to
522believe their distribution has buggy init scripts, or they have a
523failed CMOS/RTS clock battery.
524
525Enhance dumpe2fs to dump the extent information via the 'stat'
526command, and more detailed extent information via the new command
527'dump_extents'.
528    
529Update French, Polish, Czech, and Sweedish translation from the
530Translation Project.
531
532Fixed various Debian packaging issues --- see debian/changelog for
533details.

535Programmer's Notes
536------------------
537
538Fixed miscellaneous gcc -Wall warnings.
539
540Fixed memory leak in error path in ext2fs_block_iterate2()
541
542Fixed non-Linux build of the intl directory by adding support for the
543E/Q/V macros.
544
545The bitmap read/write functions now treat uninitialized bitmaps as
546unallocated; this fixes a number of problems in all e2fsprogs for ext4
547filesystems when there is a need to allocate new blocks or inodes, and
548there aren't any free blocks or inodes in the already-used block
549groups.
550
551Improve ext2fs_extent_set_bmap() to avoid creating new extents which
552get inserted into the extent tree when they are not needed.

554
555E2fsprogs 1.41.8 (July 11, 2009)
556================================
557
558Fix resize2fs's online resizing, fixing a regression which in
559e2fpsrogs 1.41.7.   (Addresses Debian Bug: #535452)
560
561Fix potential filesystem corruptions caused by using resize2fs to
562shrinking ext4 filesystems with extents enabled.  (Addresses Red Hat
563Bug: #510379)
564
565Optimize uuid_generate() to avoid running uuidd if it is not setuid or
566setgid and the currently running program doesn't have write access to
567the uuidd work directory.
568
569Add safety checks (for non-Linux systems) so that uuidd isn't run with
570file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
571will be careful not to close the file descriptor for its unix domain
572socket when it detaches itself from the controlling tty.  Also add
573safety checks so that if the unix domain socket between the uuid
574library and uuidd program is closed for any reason, both the library
575and the uuidd will return an appropriate error code instead of looping
576in an infinite loop.
577
578The e2croncheck script, which creates an LVM snapshot and then checks
579the ext3/4 filesystem via the LVM snapshot, has been added to the
580contrib directory.
581
582Fix filefrag program for files that have more than 144 extents.
583
584Update French, Polish, Czech, Indonsian, and Sweedish translation from
585the Translation Project.
586
587Fixed various Debian packaging issues --- see debian/changelog for
588details.  (Addresses Debian Bug #535530)
589
590Update/clarify man pages.
591
592Programmer's Notes
593------------------
594
595Fix compilation problem when configured with --disable-uuid.
596
597Don't build uuidgen if configured with --disable-uuid.
598
599Add the new library function ext2fs_test_inode_bitmap_range(), and
600optimized ext2fs_test_block_bitmap_range(), which will be needed for
601future optimizations for e2fsck.
602
603Fix makefile dependencies for libcom_err so that the Makefiles work
604well on non-GNU make program.  (Addresses Sourceforge Patches: #2813809)
605
606Enhance the build system so that the full set of commands executed by
607the Makefiles are displayed, instead of the Linux kernel summary
608output, if the build was configured with --enable-verbose-makecmds, or
609if GNU make is in use and the V variable is non-null, i.e., via "make
610V=1".
611
612
613E2fsprogs 1.41.7 (June 29, 2009)
614================================
615
616Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
617uninitalized data into the portion of the inode beyond the first 128
618bytes when operating on inodes mapped via extents; potentially
619corrupting filesystems.
620
621Fix memory leaks in e2fsprogs, including a very large memory leak
622which can cause e2fsck to run out of memory when checking very large
623filesystems using extents.
624
625The logsave program will now filter out the ^A and ^B characters when
626writing to the console.
627
628Harden ext2fs_validate_entry() so that lsdel will not read beyond the
629end of the block even if the directory block is corrupted.
630
631Fix debugfs from core dumping if the logdump command fails to open the
632output file.
633
634Enhance badblocks to print the currently tested block number when
635interrupted with ^C.
636
637Fix lsattr to exit with a non-zero status when it encounters errors.
638(Addresses RedHat Bugzilla #489841)
639
640Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
641filesystems as the kernel when encoding rec_len >= 64k.  For 64k
642filesystems (currently all that is supported by e2fsprogs, this is
643only a minor corner case).
644
645Resize2fs will now update the journal backup fileds in the sup0erblock
646if the journal is moved; this avoids an unnecessary full fsck after
647resizing the filesystem.  (Addresses RedHat Bugzilla: #505339)
648    
649Fix libext2fs to properly initialize i_extra_size when creating the
650journal and resize inodes.
651
652Change badblocks to allow block sizes larger than 4k.
653
654Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
655
656Update Chinese and Czech translation from the Translation Project.
657
658Clean up various man pages.  (Addresses Debian Bug #531385 and #523063)
659
660
661Programmer's Notes
662------------------
663
664Add --disable-libuuid option to configure which uses an in-system
665installed version of libuuid; the private version is enabled by
666default.
667
668Add --valgrind-leakcheck option to the test_script program which runs
669valgrind with the appropriate options to find memory leaks.
670
671
672E2fsprogs 1.41.6 (May 30, 2009)
673===============================
674
675Fix a critical regression in e2fsck introduced version 1.41.5 which
676can undo updates to the block group descriptors after a journal replay.
677
678If e2fsck receives an I/O error while replaying the journal, prompt
679the user whether they want to ignore the error or not; if e2fsck is
680run in preen mode, force fsck to abort the preen pass.
681
682Fix a bug which would cause e2fsck to core dump if the filesystem
683contains a corrupt extent header, and the user declines to clear the
684inode.  (Addresses Sourceforge Bug: #2791794)
685    
686Fix e2fsck to restart only once in the case of multiple block groups
687which inodes in use that are in the uninitialized part of the block
688group's inode table.
689
690To reduce user confusion, if the /etc/mtab file is missing
691ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
692new, explicit error code to indicate this case.  This will cause
693e2fsck to give a clearer error message when the user is using buggy
694rescue CD's that don't properly set up /etc/mtab.  (Addresses Debian
695Bug: #527859)
696    
697Fix e2fsck so that if the primary group descriptors are corrupted, but
698the backup superblock is entirely invalid, to go back to using (and
699fixing) the priary group descriptors instead of completely giving up
700on the filesystem.  (Addresses Debian Bug: #516820)
701    
702Change e2fsck to not abort a preen pass if an inode is found to have
703i_file_acl_hi non-zero.  Ext3 filesystems don't care, and newer
704kernels (post 2.6.29) will ignore this field.  So let's fix it
705automatically during the preen pass instead of forcing the user to fix
706this up manually.  (Addresses Debian Bug: #526524)
707    
708Add resource tracking for e2fsck passes 1b through 1d.
709
710Speed up e2fsck by eliminating unnecessary journal checks if the
711filesystem is already mounted and doesn't need recovery (since the
712kernel would have run the journal when the filesystem was mounted.)
713Also speed up e2fsck by avoiding unnecessary block group descriptor
714updates in ext2fs_close().
715
716Add support to chattr to migrate inodes from using direct/indirect
717blocks to extents.
718
719Avoid corrupting the filesystem if there is an attempt to shrink a
720filesystem using resize2fs smaller than posible by making
721ext2fs_set_bmap() more careful not to delete the old block until the
722new block can be inserted.  In addition, fix a bug in how the minimum
723size of the filesystem (plus a safety margin) is calculated, and
724modify resize2fs to refuse to shrink the filesystem below that minimum
725size without the force flag.
726
727Teach blkid to try to figure out DM device names using take advantage
728of information in sysfs when running on kernels (2.6.29 and later)
729which provide this information in /sys/block/dm-<N>/dm/name; this is
730much faster than scanning for the devncie number in /dev/mapper.
731
732Fix blkid to prefer /dev/mapper/<name> device names instad of the
733private /dev/dm-X names.
734
735Add an -a option to debugfs's close_filesys command which writes any
736changes to the superblock or block group descriptors to all of the
737backup superblock locations.
738    
739Add support to the filefrag program to use the FIEMAP ioctl.
740
741Update Chinese translation from the Translation Project.
742
743Clean up various man pages.  (Addresses Red Hat Bugzilla: #502971 and
744Launchpad Bug: #381854)
745
746Fixed various Debian packaging issues --- see debian/changelog for
747details.  (Addresses Debian Bug #506064)
748
749
750Programmer's Notes
751------------------
752
753Add test code to make sure e2fsck's problem.c doesn't have two problem
754codes assigned to duplicate values.
755
756Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
757(Addresses Sourceforge Bug: #2780205)
758
759Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
760function declaration for init_resource_track() and
761print_resource_track() when RESOURCE_TRACK is not defined.
762
763The test code which is used to build the tst_csum progam has been
764moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
765avoid compile problems caused by not having a prototype for
766ext2fs_group_desc_csum().  (Addresses Sourceforge Bug #2484331)
767
768Update the config.guess and config.sub file to the latest from the
769FSF, to allow e2fsprogs to build on the avr32 platform.  (Addresses
770Debian Bug: #528330)
771
772Add a new function, ext2fs_extent_open2(), which behaves like
773pext2fs_extent_open(), but uses the user-supplied inode structure
774when opening an extent instead of reading the inode from disk.
775
776
777E2fsprogs 1.41.5 (April 23, 2009)
778=================================
779
780Fix a number of filesystem corruption bugs in resize2fs when growing
781or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
782is not mounted).
783
784Debugfs can now set i_file_acl_high via the set_inodes_field command,
785and print a 64-bit file acl.  This is useful for debugging filesystem
786corruptions where the high bits of i_file_acl_high are set.  E2fsck
787will detect and fix non-zero i_file_acl_high on 32-bit filesystems
788since some Linux kernel versions pay attention to this field even when
789they shouldn't.
790
791Speed up e2fsck when checking clean filesystems by avoiding
792unnecessary block reads, and coalescing the block group descriptor
793blocks so they are read using a single read operation.
794
795The libuuid library will now close all file descriptors before running
796uuidd.  This avoids problems when the calling program has open sockets
797which then never get closed because uuidd is a long-running helper
798daeomn.  (Addresses Launchpad bug: #305057)
799
800In order to avoid unnecessary full filesystem checks by e2fsck after
801an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
802the backup superblocks.  (Addresses Red Hat Bugzilla: #471925)
803
804Mke2fs will avoid trying to create the journal when run in
805superblock-only mode (mke2fs -S), since the left-over journal in the
806inode table will cause mke2fs to fail.
807
808Fix a bug in libext2fs functions that check to see if a particular
809device or filesystem image is mounted, which would cause these
810functions to report that a file identical to the (relative) pathname
811used by a pseudo-filesystem was mounted when in fact it was not.
812
813Update Czech translation from the Translation Project.
814
815Add Chinese (simplified) translation from the Translation Project.
816
817Fix support for external journals (which was broken in e2fsprogs
8181.41.4).
819
820Fix a regression in debugfs where the "stat" command when no
821filesystem was open would cause debugfs to crash with a segmentation
822violation.
823
824Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
825used to support filesystems without a journal.  Update the blkid
826library so it understands this.
827
828The blkid library will remove an entry from the blkid cache
829representing the entire disk if partitions are found, since presuambly
830the device previously had no partition table, but has now transitioned
831to using a partition table.
832
833Add a check to mke2fs and tune2fs that the argument to the -m option
834(which specifies the reserved ratio) must be greater than zero.
835(Addresses Debian Bug: #517015)
836
837Add support for tracking the number kilobytes written to the
838filesystem via the superblock field s_kbytes_written.  It will be
839updated by the kernel as well as by e2fsprogs programs which write to
840the filesystem.  This is useful for tracking the wear to filesystems
841on Solid Sstate Drives.
842
843Fix compatibility issue in the libext2fs info file and makeinfo
844version 4.12.  (Addresses Red Hat Bugzilla: #481620)
845
846Update/clarify man pages.  (Addresses Debian Bug: #515693, #365619)
847
848Fixed various Debian packaging issues --- see debian/changelog for
849details. (Addresses Debian Bug: #506279)
850
851Programmer's Notes
852------------------
853
854Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
855Bug: #521602)
856
857Fix various gcc compilation warnings and other programming cleanups.
858(Addresses Red Hat Bugzilla: #486997)
859
860Add support for building the blkid command statically.
861
862Add support for disabling the built-in blkid library in favor of a
863system-installed blkid implementation via the configure option
864--disable-libblkid.
865
866
867E2fsprogs 1.41.4 (January 27, 2009)
868===================================
869
870Fixed a bug which could sometimes cause blkid to return an exit value
871of zero for a non-existent device (Addresses Debian Bug: #502541)
872
873Blkid will now recognize ext3 filesystems that have the test_fs flag
874set as ext3 filesystems.
875
876The blkid library will now recognize btrfs filesystems and swap
877devices currently used by user-level software suspend.
878
879Tune2fs now updates the block group checksums when changing the UUID
880to avoid causing e2fsck to complain vociferously at the next reboot.
881
882Tune2fs's inode size resizing algorithms have been fixed so it is not
883vastly inefficient for moderate-to-large filesystems, due to some
884O(n**2) and O(n*m) algorithms that didn't scale well at all.
885
886Fix tune2fs's inode resizing algorithm so it will not corrupt
887filesystems laid out for RAID filesystems; in addition, tune2fs will
888refuse to change the inode size for filesystems that have the flex_bg
889feature enabled.  (This is a limitation in the current implementation
890of tune2fs -I.)
891
892E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
893filesystems with 32-bit block numbers, when the headers for 64-bit
894block numbers was added.  This regression has been fixed.
895
896Debugfs's ncheck command has been fixed to avoid printing garbage
897characters at the end of file names.
898
899Fix resize2fs for ext4 filesystems.  Some blocks that that need moving
900when shrinking filesystems with uninit_bg feature would not be moved.
901In addition, blocks and inode table blocks were not being correctly
902freed when shrinking filesystems with the flex_bg feable, which caused
903resize2fs -M to fail.  Finally, when blocks are moved, make sure the
904uninitialized flag in extents is preserved.
905
906Fix bug which caused dumpe2fs to abort with an error if run on a
907filesystem that contained an external journal.
908
909Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
910for this in argv[0] to provide better legacy support for these
911distributions.  This is a practice that should NOT be continued,
912however.
913
914Mke2fs now has a new option -U, which allows the user to specify the
915UUID that should be used for the new filesystem.
916
917Mke2fs will treat devices that are exactly 16TB as if they were 16TB
918minus one block.  This allows users who have read that ext3 supports
919up to 16TB filesystems and who create a 16TB LVM to not get confused,
920since the true limit is really 16TB minus one block.
921
922E2fsck will no longer abort an fsck run if block group has an errant
923INODE_UNINIT flag.
924
925E2fsck now distinguishes between fragmented directories and fragmented
926files in verbose mode statistics and in the fragcheck report.
927
928Fix a bug in e2fsck which casued it double count non-contiguous
929extent-based inodes.
930
931E2fsck will leave some slack space when repacking directories to allow
932room for a few directory entries to be added without causing leaf
933nodes to be split right away.
934
935Fix a bug which caused e2fsck to crash when it comes across a
936corrupted interior node in an extent tree with the error message:
937"Error1: Corrupt extent header on inode XXXXXX"
938
939E2fsck problem descriptions involving the journal are no longer
940referred to as "ext3" problems, since ext4 filesystems also have
941journals.
942
943Fix a long-standing bug in e2fsck which would cause it to crash when
944replying journals for filesystems with block sizes greater than 8k.
945
946Update Catalan translation from the Translation Project.
947
948Fixed various Debian packaging issues --- see debian/changelog for
949details. (Addresses Debian Bugs: #503057, #502323, #511207)
950
951Programmer's Notes
952------------------
953
954Fix build of e2fsck.profiled, and add support for building profiled
955binaries in the misc directory if configured with --enable-profile.
956
957The ext2fs_open() function now performs more sanity checks on the
958superblock to avoid potential divide by zero errors by other parts of
959library.
960
961The ext2fs_read_inode_full() function now has a safety check to avoid
962a segmentation fault on corrupted filesystems.
963
964The ext2fs_new_inode() function now has a sanity check so that if the
965s_first_inode field in the superblock is insane, it will return
966EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
967
968To avoid segmentation faults, ext2fs_block_alloc_stats() and
969ext2fs_inode_alloc_stats() now validates the passed inode or block
970number to avoid overrunning an array boundary.
971
972Various signed/unsigned errors for variables containing block numbers
973have been fixed.
974
975Accomodations for gcc's stupidity in not realizing that constant
976strings that do not contain a '%' character are safe to use in format
977strings have been made so that distributions that want to compile
978e2fsprogs with -Werror=format-security have an easier time doing so.
979
980Added a new 64-bit getsize interface, ext2fs_get_device_size2().
981
982Added the utility make-sparse.c to the contrib directory.
983
984The ext2fs_block_iterate2() function now reflects errors from
985ext2fs_extent_set_bmap() to the caller, if the callback tries to
986change a block on an extent-based file, and ext2fs_extent_set_bmap()
987fails for some reason (for example, there isn't enough disk space to
988split a node and expand the extent tree.
989
990The ext2fs_block_iterate2() function will preserve the uninit flag in
991extents when the callback function modifies a block in an extent-based
992file.
993
994E2fsck will now flag filesystems that have an insane s_first_ino field
995in their superblock, and attempt to use a backup superblock to repair
996the filesystem.
997
998
999E2fsprogs 1.41.3 (October 12, 2008)
1000===================================
1001
1002E2fsck has been fixed so it prints the correct inode number for
1003uinit_bg related problems.
1004
1005E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1006is available on linux.  This can be disabled via a configuration
1007option in /etc/e2fsck.conf.
1008
1009Fix a file descriptor leak in libblkid when checking to see if an ext4
1010or ext4dev module exists.
1011
1012Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1013while trying to close a filesystem can lead to infinite loops.

1018Hat Bugzilla: #465984)
1019    
1020Add a check in the Unix I/O functions in libext2fs so that when a
1021device is opened read/write, return an error if the device is
1022read-only using the BLKROGET ioctl.
1023
1024Fix debugfs's ncheck command so that it prints all of the names of
1025hardlinks in the same directory.
1026
1027Fix a bug in libblkid so it correctly detects whether the ext4 and
1028ext4dev filesystems are available, so that the ext4dev->ext4
1029fallback code works correctly.

1041E2fsprogs 1.41.2 (October 2, 2008)
1042==================================
1043
1044Fix e2fsck's automatic blocksize detection.  This fixes a regression
1045from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1046specifies a block number using the -b option if the blocksize option
1047isn't also specified using -B.  Unfortunately, users very commonly
1048invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1049superblock; in fack e2fsck will often suggest this kind of command
1050line.  Oops.
1051
1052Enhance the debugfs's "ncheck" command so it will print all of the
1053pathnames for the specified inodes.  (Previously, in some cases ncheck
1054might not print a pathname for an inode at all if some of the other
1055inodes had multiple hard links.)
1056
1057Enhance debugfs's "hash" command so the hash seed can be specified via
1058a command-line option.  In addition, allow the hash algorithm to be
1059specified by name instead of just by number.
1060
1061Fix e2fsck so that we don't accidentally print the translation file's
1062header when asking the user a custom question so there is no prompt
1063defined for a particular problem record.  For example, the question
1064"Run journal anyway" will get the PO header tacked on because e2fsck
1065erroneously passed the null string to _().  (Addresses Launchpad Bug:
1066#246892)
1067
1068Enhance badblocks so that it can test a normal file which is greater
1069than 2GB.
1070
1071Enhance the badblocks command so that it displays the time and
1072percentage complete when in verbose mode.  (Addresses Debian Bug:
1073#429739)
1074
1075Fix a potential memory leak in a error handling path in debugfs's
1076ncheck function.
1077
1078Fix a potential memory corruption problem if a memory allocation fails
1079in resize2fs.
1080
1081Fix the usage message for debugfs's logdump command to be consistent
1082with its man manpage.
1083
1084Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
1085and Sweedish translation from the Translation Project.
1086
1087Add documentation for the file I/O functions to the libext2fs.texinfo
1088file.  (Addresses Debian Bug: #484877)
1089    
1090Update and clarified various man pages.  (Addresses Launchpad Bug

1096Programmer's Notes
1097------------------
1098
1099Fix a potential file descriptor leack in libcom_err by setting the
1100close-on-exec flag for a fd used for debugging.  (Addresses Red Hat
1101Bugzilla #464689)
1102
1103Fix a potential race in libcom_err by using sem_post/sem_init.  SuSE
1104has been carrying a patch for a long time to prevent a largely
1105theoretical race condition if a multi-threaded application adds and
1106removes error tables in multiple threads.  Unfortunately SuSE's
1107approach breaks compatibility by forcing applications to link and
1108compile with the -pthread option; using pthread mutexes has
1109historically been problematic.  We fix this by using sem_post/sem_init
1110instead.
1111
1112Fix e2fsprogs-libs build failure due to 'subs' target.  (Addresses
1113Sourceforge Bug: #2087502)
1114
1115Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
1116libraries when using ELF shared libraries.
1117
1118Fix ELF shared library when building on systems that don't already
1119have the e2fsprogs shared libraries already installed.  (Addresses
1120Sourceforge Bug: #2088537)
1121
1122Fix the pkg-config files so they work correctly when linking with
1123static libraries and fix the include directory so programs don't have
1124to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
1125instead.  (Addresses Sourceforge Bug: #2089537)
1126    
1127Make sure ext2fs_swab64() is compiled for all platforms, and not just
1128for x86.  (Addresses Debian Bug: #497515)
1129    
1130Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1131non-x86 platforms.  (They had been removed for x86 earlier.)
1132
1133Fix diet libc compilation support, which had bitrotted due to lack of
1134TLC.  Fixing this improves general portability.
1135
1136When installing the link library when using ELF shared libraries,
1137avoid using absolute pathnames if the link library and the shared
1138library are installed in the same directory.  (Addresses Sourceforge
1139Bug: #1782913)
1140
1141Fix gen-tarball so it will work even if the top-level directory has
1142been renamed to something other than "e2fsprogs".  Also make
1143gen-tarball print the size of the resulting tar.gz file.
1144
1145
1146E2fsprogs 1.41.1 (September 1, 2008)
1147====================================
1148
1149Many people are forgetting to update their mke2fs.conf file, and this
1150causes ext3, ext4, and ext4dev filesystems won't get created with the
1151proper features enabled.  We address this in two ways.  First, mke2fs
1152will issue a warning if there is not definition for an ext3, ext4, or
1153ext4dev filesystem and the user is trying to create such a filesystem
1154type.  Secondly, when installing from a source build, "make install"
1155will provide basic configuration file handling for /etc/mke2fs.conf.
1156If it exists, and does not mention ext4dev, it will be moved aside to
1157/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1158be installed.  If the existing /etc/mke2fs.conf file does mention
1159ext4dev, then "make install" will install official mke2fs.conf file as
1160/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1161they should look to see if any changes need to be merged.
1162
1163The mke2fs program will now create the journal in the middle of the
1164filesystem, since this minimizes seek times on average for fsync-heavy
1165workloads.  In addition, mke2fs will now create journals using extents
1166for filesystems that support them.  This results in a more efficient
1167encoding for the journal since it eliminates the need for using
1168indirect blocks.
1169
1170The mke2fs program will avoid allocating an extra block to the
1171journal.  (Addresses Sourceforge Bug: #1483791)
1172
1173Mke2fs will correctly enforce the prohibition against features
1174(specifically read-only features) in revision 0 filesystems.  (Thanks
1175to Benno Schulenberg for noticing this problem.)
1176
1177Mke2fs previously would occasionaly create some slightly non-optimally
1178placed inode tables; this bug has been fixed.
1179
1180The mke2fs and tune2fs programs now print the correct usage message
1181describing the maximum journal size.  (Addresses Debian Bug: #491620)
1182
1183Add support for setting the default hash algorithm used in b-tree
1184directories in tune2fs (from a command-line option) or mke2fs (via
1185mke2fs.conf).  In addition, change the default hash algorithm to
1186half_md4, since it is faster and better.
1187
1188The blkid library will now recognize MacOS hfsx filesystems, and
1189correctly extract the label and uuid for hfs, hfsx, and hfsplus
1190filesystems.  (Addresses Sourceforge Feature Requests: #2060292)
1191
1192The blkid library has improved detection of JFS and HPFS filesystems.
1193(Addresses Launchpad Bug: #255255)
1194
1195The blkid library is now much more efficiently handling devicemapper
1196devices, mainly by no longer using the devicemapper library.  This can
1197speed up access for systems with a large number of device mapper
1198devices.
1199
1200Blkid had a number of cache validation bugs in libblkid that have been
1201fixed.   (Addresses Debian Bug: #493216)
1202
1203Resize2fs will now properly close out the "updating inode references"
1204progress bar so there is a newline printed before printing the final
1205"resize is successful" message.
1206
1207Resize2fs will now correctly handle filesystems with extents and/o
1208uninitialized block groups correctly when file/directory blocks need
1209to relocated (i.e., when shrinking a filesystem or if the resize_inode
1210is not present).  To support this, the ext2fs library now supports
1211initializing inode and block bitmaps that are not yet initialized when
1212allocating them using ext2fs_new_block() and ext2fs_new_inode().  In
1213addition, e2fs_block_iterate2() can now support changing the location
1214of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1215been optimized to avoid creating unnecessary new extents when updating
1216the location of blocks in the extent tree.  This will also help out
1217e2fsck's recovery of obscurely corrupted filesystems with extents,
1218when blocks are claimed by multiple inodes.
1219
1220Add support for on-line resizing ext4 filesystem with the flex_bg
1221filesystem feature.  The method for doing so is not optimal, but to do
1222a better job will require kernel support.
1223
1224E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1225debugfs programs to not be able to read e2image files; the signed
1226vs. unsigned bug in the code which read bitmaps from the e2image has
1227been fixed.   (Addresses Debian Bug: #495830)
1228
1229Resize2fs is now correctly managing the directory in-use counts when
1230shrinking filesystems and directory inodes needed to be moved from one
1231block group to another.  This bug has been around since e2fsprogs
12321.26, and is largely harmless, but does cause a filesystem corruption
1233which will be flagged by e2fsck after the filesystem has been shrunk.
1234 
1235E2fsck will no longer issue spurious complaints about the inode size
1236caused by very large extent-based files, and by blocks reallocated
1237using fallocate() with the FALLOC_FL_KEEP_SIZE option.  (Addresses
1238Kernel Bugzilla: #11341)
1239
1240Mke2fs will now set the creation timestamp on the lost+found directory
1241and the root directory.  (More generally, all new inodes created using
1242the ext2fs library will correctly set the creation timestamp.)
1243
1244E2fsck now correctly calculates ind/dind/tind statistics in the
1245presence of extent-based files.  In addition, "e2fsck -v" will report
1246statistics of the depth of extent trees in the filesystem.  E2fsck can
1247also give an inode fragmentation report using "e2fsck -E fragcheck"
1248which can be useful when debugging the kernel block allocation
1249routines.
1250
1251Fix support for empty directory blocks in ext4 filesystems with 64k
1252blocksize filesystems.
1253
1254E2fsck will now print the depth of corrupt htree directories.
1255
1256Debugfs's htree command now correctly understands extent-based
1257directories.  It will also print out the minor hash as well as the
1258major hash.
1259
1260Debugfs has a new command which will print the supported features of
1261e2fsprogs, to enable scripts to know whether the installed version of
1262e2fsprogs can support a specific feature.
1263
1264Debugfs will now write files using extents for filesystems that
1265support them.
1266
1267The error message printed by "tune2fs -I" if the inode size was too
1268small was rather confusing, so it has been improved.  Also, we won't
1269try to create an undo log until we know that command-line-specified
1270parameters such as "tune2fs -I <inode size>" are valid.
1271
1272Given some filesystems found "in the wild" that had non-zero block
1273group checksums even though the uninit_bg/gdt_sum feature was not
1274enabled, e2fsck would issue spurious error messages.  Teach
1275ext2fs_group_desc_csum_verify() to ignore the block group checksum
1276entirely if the feature flag is not set.  (Addresses Debian Bug:
1277#490637)
1278
1279The blkid program will now print out a user-friendly listing of all of
1280the block devices in the system and what they contain when given the
1281-L option.  (Addresses Debian Bug: #490527)
1282
1283The filefrag program now has a more accurate calculation for the
1284number of ideal extents.  (Addresses Debian Bug: #458306)
1285
1286The test I/O manager is now enabled by default, but its overhead is
1287only incurred when it would be enabled via the TEST_IO_FLAGS or
1288TEST_IO_BLOCK environment variables.
1289
1290Typographical errors in various program strings and usage messages
1291have been fixed; most of these were pointed out by the e2fsprogs
1292message catalog translators.  (Thanks, translators!)
1293
1294Update and clarified various man pages, as well as some typographical
1295errors in the libext2fs texinfo file.
1296
1297Fixed various Debian packaging issues --- see debian/changelog for
1298details.
1299
1300Add Indonesian and update French, Polish, Dutch, German, Sweedish,
1301Czech, and Vietnamese Translations.  (Addresses Debian Bugs: #313697,
1302#401092)

1304Programmer's Notes
1305------------------
1306
1307Fix portability problem with the badblocks group; for systems that
1308don't have nanosleep(), try using usleep() instead.
1309
1310The "make check" target in the e2fsck directory now sets
1311LD_LIBRARY_PATH before running the various e2fsck internal library
1312regression tests.
1313
1314The crc32 regression test in the e2fsck library is now portable to
1315greater varienty of environments, including big-endian systems and
1316when cross-building e2fsprogs for embedded systems.  (Addresses
1317Sourceforge Bug: #2019287)
1318
1319The ext2fs_extent_set_bmap() had some bugs when setting the first
1320block in a file, or when replacing a single block extent.  Those cases
1321fortunately were came up relatively rarely when e2fsck was checking
1322files, but caused some problems when resize2fs was shrinking
1323extent-based files.
1324
1325Fix a potential core-dumping bug in libe2p's iterate_on_dir()
1326function.
1327
1328Various ext2fs library functions --- ext2fs_block_iterate2(),
1329ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
1330allocated memory to avoid memory leaks in all of their error return
1331paths.
1332
1333Ext2ed was failing to build because masix support had been removed in
1334the rest of e2fsprogs, so ext2ed no longer has masix support, either.
1335
1336The configure script now respects the LDFLAGS environment variable if
1337it is set when configure is called.  (Addresses Sourceforge Feature
1338Request: #1937287)
1339
1340Libuuid is now more portable to the Windows platform.  (Addresses
1341Sourceforge Feature Request: #1937287)
1342
1343The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1344bare echo commands so that configure flags such as --quiet work
1345correctly.  (Addresses Sourceforge Patches: #2058794)
1346
1347A few uses of sprintf have been removed from the ext2fs library to
1348make life easier for bootloaders with a limited libc environment.
1349(Addresses Sourceforge Bug: #2049120)
1350
1351The ext2fs_read_inode() checks the validity of the inode number passed
1352to it earlier, to avoid doing some needless work when it would fail
1353anyway.
1354
1355The ext2fs_open() checks the validity of the blocksize parameter
1356passed to it earlier, to avoid doing some needless work when it would
1357fail anyway.
1358
1359Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1360top-level Makefile.  That automatic rule is used to better support
1361SCCS, but it caused problems for a particular niche distribution which
1362likes to use configure.sh files to store the configure options used to
1363build a package.  Unfortuntaely GNU make will use the configure.sh to
1364replace the configure script, resulting in a self-inflicted fork bomb
1365leading to an out-of-memory crash.
1366
1367To support old GNU C compilers don't use C99/C++ comments, but only
1368K&R style comments, and don't try to use __builtin_expect if __GNUC__
1369is less than 3.  (__builtin_expect is only supported for gcc versions
13702.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1371this is an optimization, we only try to use __builtin_expect for gcc 3
1372and up.)
1373
1374In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
1375__LITTLE_ENDIAN, which are only defined by glibc's header files and
1376hence isn't portable.
1377
1378For the convenience for some distributions that need a static tune2fs,
1379the Makefile for misc/ now has a tune2fs.static target.
1380
1381The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1382for extent-based files
1383
1384The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1385files.
1386
1387All source files no longer have any trailing white space.
1388
1389The io_channel_read_blk64() and io_channel_write_blk64() functions are
1390now functions instead of C preprocessor macros to provide better
1391forward compatibility.
1392
1393The e2fpsrogs translation template now expands the @x abbrevation.
1394
1395Various namespace leackages in libblkid, libe2p, and libext2fs have
1396been fixed.
1397
1398Fix a parallel build problem in e2fsprogs.
1399
1400E2fsprogs is now more portable to Solaris.
1401  * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
1402    are always present.
1403  * Scripts do not assume that /bin/true is always in /bin
1404  * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
1405  * Flush stdio handles before calling setbuf(), since Solaris will
1406    discard any pending output to the stream.
1407  * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
1408    picky about which C compiler can beused for SUSv3 conformance.
1409    Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
1410    and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
1411    Since we need some SUSv3 functions, consistently use SUSv3 so
1412    that e2fsprogs will build on Solaris using c99.
1413  * Solaris C99 does not support varargs C preprocessor macros
1414  * Solaris header files pollute the C namespace if in/netinet.h
1415    is included, which conflicts with e2fsprogs' use of the kmem_cache_t
1416    typedef.
1417  * Solaris ships with a pathetically ancient shell in /bin/sh so we
1418    avoid the use of various more avanced shell constructs such as $().
1419
1420The "make rpm" command will now take some extra configure optiosn from
1421the build environment without needing to patch the source tree.
1422
1423The ext2fs_add_dir_block() function will now grow the dblist more
1424aggressively as an optimization to avoid copying the array too often.
1425
1426The e2fsck_write_bitmaps() will write the block and inode bitmaps
1427together instead of in two passes.
1428
1429
1430E2fsprogs 1.41 (July 10, 2008)
1431==============================
1432
1433Add support for ext4 filesystem features, in particular extents,
1434uninit_bg, flex_bg, huge_file, and dir_nlink features.  Also add
1435support for checking journal checksums.  Debugfs will print new
1436superblock and inode fields that were defined for ext4.  For example,
1437the nanosecond and i_version fields of an inode, and the
1438s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1439Note: Resize2fs doesn't currently support the combination of flex_bg
1440and !resize_inode.  (Addresses Debian Bug: #388452, #425477)
1441
1442Tune2fs can support migrating a filesystem from using 128 byte inodes
1443to 256 byte inodes, so it can take advantage of the full features of
1444ext4.
1445
1446Add support for "undo" support.  E2fsck and mke2fs can optionally
1447record an undo log which can replayed by the program e2undo.
1448
1449E2fsck could damage a filesystem by trying to relocate inode tables
1450due to corrupted block group descriptors, where the attempted inode
1451table relocation would do far more harm than good.  E2fsck has been
1452fixed to detect this these sorts of corrupted block group descriptors
1453much earlier in e2fsck processing, so it can try to use the backup
1454superblock and block group descriptors first.  This should be a much
1455better strategy for recovering these types of corrupted filesystems.
1456(Addresses Sourceforge Bug: #1840291)
1457
1458E2fsck will display a more understandable message when the last check
1459field in the superblock is in the future.  (Addresses Debian Bug:
1460#446005).
1461
1462E2fsck now performs more extensive and careful checks of extended
1463attributes stored in the inode.
1464
1465Enhance mke2fs to print a more explanatory error message when
1466ext2fs_get_device_size() returns EFBIG.  (Addresses Debian Bug:
1467#488663)
1468
1469Fix mke2fs to use a default block size of 4k when formatting an
1470external journal device.  This is done by using a fixed filesystem
1471type list that consists only of the single filesystem type "journal"
1472when looking up configuration keys in /etc/mke2fs.conf.  (Addresses
1473Debian Bug: #488663)
1474
1475Speed up how mke2fs writes the journal data blocks by writing the disk
1476blocks in larger chunks.
1477
1478Fix blkid handling of stale devices.  Fix a bug which could cause a
1479core dump while garbage collecting the blkid cache, and assure that
1480blkid_find_dev_with_tag() never returns a non-existent device.  Also,
1481if a filesystem is found at a new /dev location, eliminate any
1482duplicate stale entries which can not be verified.
1483(Addresses Debian Bugs: #487758, #487783)
1484    
1485Add more paranoid checks for LVM volumes and swap partitions in
1486blkid's probe function, to reduce the chances of false positives.
1487
1488The mke2fs program now has a much more sophisticated system for
1489controlling configuration parameters of a newly created filesystem
1490based on a split filesystem and usage type system.  The -t option to
1491mke2fs was a deprecated alias to -c; it now specifies a filesystem
1492type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1493separated usage list.  The filesystem type information and type
1494information is used to extract configuration parameters from the
1495/etc/mke2fs.conf file.
1496
1497The mke2fs program will no longer complain and request the -f option
1498when the user tries to create a filesystem with greater than 2**31
1499blocks.
1500
1501When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1502adjust the mke2fs.conf file so filesystems for the Hurd are created
1503with a blocksize of 4096 and inode size of 128, which is all it knows
1504how to handle.  (Addresses Debian Bug: #471977)
1505    
1506Mke2fs will always make sure that lost+found always has at least 2
1507blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1508
1509Resize2fs will now print the minimum needed filesystem size if given
1510the -P option, and will resize the filesystem to the smallest possible
1511size if given the -M option.
1512
1513Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1514blocks are consumed during an off-line resize.
1515
1516The "ls" command in debugfs now supports the -p option, which causes
1517it to quote the filenames so that spaces or tabs in directory entries
1518are easily visible.  (Addresses Red Hat Bugzilla: #149480; Addresses
1519Sourceforge Feature Request: #1201667)
1520
1521Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1522e2image file.
1523
1524The chattr program will return a non-zero exit code in case of
1525failures, and error messages can be suppressed with the -f option.
1526(Addresses Red Hat Bugzilla: #180596)
1527
1528Fix a bug in badblocks which caused it to overrun an array and likely
1529crash if more than 8 test patterns are specified using the -t option.
1530(Addresses Debian Bug: #487298)
1531    
1532Add support to badblocks to limit how quickly it reads from the disk
1533drive (so it can be used for background scrubbing), and so it will
1534abort after finding a given number of errors.
1535
1536Remove support for the legacy big-endian filesystem format which only
1537existed on extremely long-dead PowerPC kernels almost a decade ago.
1538
1539Remove MASIX support from e2fsprogs.
1540
1541Add I/O statistics reporting to e2fsck.

1569
1570Avoid using predictable filenames in /tmp in blkid's regression test
1571suite.  Also remove bashism's in the regression test script.
1572
1573If the configure script is given --with-diet-libc, don't use thread
1574local storage, since diet libc doesn't support TLS.  (Addresses
1575Sourceforge Bug: #2000654)
1576    
1577Fix the blkid regression test suite to tolerate older versions of
1578mkswap that don't support the -U option.
1579
1580A few library routines have been converted to support 64-bit block
1581numbers; in particular, the I/O manager functions, the test_io,
1582inode_io, and unix_io managers have all be converted to support 64-bit
1583operation.
1584
1585Debugfs can now be extended for use by test programs.  See
1586lib/ext2fs/extents.c for an example for how it can be used.  The test
1587program links against the debugfs object files, and provides
1588additional commands by defining an auxiliary libss command table.
1589
1590The lazy_bg filesystem feature, which was only used by developer's
1591testing, has been removed since it has been largely supplanted by
1592uninit_bg.  This also simplifies the code.

1624================================
1625
1626When deciding whether or not to revalidate a blkid cache entry, if the
1627device's mtime is newer than the last time the cached entry was
1628validated, force a revalidation.
1629
1630Fix a potential data corruption bug in e2fsck in the journal replay.
1631The chances of this is happening is extremely remote, especially the
1632default data=ordered or data=writeback modes.  However, if a block
1633which has been journalled starts with the first four bytes 0xc03b3998,
1634when e2fsck replays the journal, those four bytes will be replaced
1635with zero's.  Fortunately, it is highly, highly unlikely for e2fsck
1636metadata to begin with those fatal 4 byte sequence, and unless
1637data=ordered mode is in use, data blocks are never journaled.

1655issues.  None of them are serious given that uuidd runs setuid as a
1656unprivileged user which has no special access other than libuuid
1657directory, but it's good to get them fixed.
1658
1659One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1660work correctly with in-inode extended attributes.

1667Fix debugfs and tune2fs to correctly handle daylight savings time when
1668parsing a time string.
1669
1670Fixed spelling mistakes, typos, and otherwise clarified man pages.
1671
1672Fix fsck completion bars when multiple filesystems were being checked
1673in parallel.  (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
1674#203323, Addresses Sourceforge Bug: #1926023)
1675
1676Fix fsck so that progress information is sent back correctly when
1677multiple filesystems are being check and the output of fsck is being
1678redirected to a file descriptor.  Also, include the device name (w/o
1679spaces) in the progress information sent back via a file descriptor.

1721E2fsprogs 1.40.8 (March 13, 2008)
1722=================================
1723
1724Fixed e2image -I so it works on image files which are larger than 2GB.
1725
1726Fixed e2fsck's handling of directory inodes with a corrupt size field.  If
1727the size is larger than the number of blocks found in the inode, don't
1728try to allocate extra empty blocks at the end of the directory to make
1729up the difference; there's no point to doing that.  In addition, if
1730the size is not a multiple of a blocksize, always fix it.
1731
1732E2fsck handled a pass 2 "should never happen error" by not giving
1733enough information and then core dumping.  Unfortunately, it was all
1734too easy to trigger the "should never happen" situation if a
1735directory's inode size was not correct.  This has been fixed, but
1736e2fsck has also been taught how to handle this situation more
1737gracefully, by simply removing the inode hash tree information, so
1738that it can be rebuilt again after e2fsck's pass 3.  (Addresses
1739Launchpad Bug: #129395)
1740
1741Resize2fs had a bug resizing large inodes with extended attributes
1742that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1743completely on big-endian systems such as PowerPC.  The bug should be
1744completely fixed now.  Yay for regression test suites.  (Addresses Red
1745Hat Bugzilla: #434893)
1746

1749up to become the new German translation maintainer!  (Addresses Debian
1750Bugs: #302512, #370247, #401092, #412882).
1751
1752When e2fsck is clearing a corrupt inode's HTREE directory information,
1753make it clear that it is just clearing the HTREE information, not the
1754entire inode.
1755
1756Fixed spelling mistakes, typos, and otherwise clarified man pages.  
1757
1758Programmer's notes
1759------------------
1760
1761Add new functions, ext2fs_dblist_get_last() and
1762ext2fs_dblist_drop_last(), which allows the caller to examine the last
1763directory block entry added to the list, and to drop if it necessary.
1764
1765Fixed a portability problem in libblkid with DJGPP.
1766
1767Fix an obvious typo in an "internal error" message in e2fsck.  Thanks
1768to Philipp Thomas for pointing this out.

1774E2fsprogs 1.40.7 (February 28, 2008)
1775====================================
1776
1777Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1778depreciate the -s option, since it can result in filesystems which
1779e2fsck can't fix easily.  There are very good reasons for wanting to
1780disable sparse_super; users who wants to turn off sparse_super can use
1781debugfs.  (Addresses Sourceforge Bug: #1840286)
1782    
1783Add missing options to mke2fs's usage message.  (Addresses Sourceforge
1784Bug: #1751393)
1785    
1786Fix bug in resize2fs when large (greater than 128 byte) inodes are
1787moved when a filesystem is shrunk; it was only moving the first 128
1788bytes, so extended attributes were not getting moved.  (Addresses Red
1789Hat Bugzilla: #434893)

1791E2fsck now prints an explicit message when the bad block inode is
1792updated, to avoid confusion about why the filesystem was modified.
1793(Addresses Sourceforge Bug: #756460)
1794    
1795Allow mke2fs and tune2fs manipulate the large_file feature.
1796Previously we just let the kernel and e2fsck do this automatically,
1797but e2fsck will no longer automatically clear the large_file feature.
1798It still isn't really necessary to worry about this feature flag
1799explicitly, but some users seem to care.  (Addresses Red Hat Bugzilla:

1806reporting a free block more than once if there are too few free blocks
1807in the filesystem.  (Addresses Sourceforge Bug: #1096315)
1808    
1809Change e2fsck to no longer clear the LARGE_FILES feature flag
1810automatically, when there are no more > 2GB files in the filesystem.
1811It's been almost a decade since there have been kernels that don't
1812support this flag, and e2fsck clears it quietly without telling the
1813user why the filesystem has been changed.
1814    
1815Fix bug which could cause libblkid to seg fault if a device mapper
1816volume disappears while it is being probed.  (Addresses RedHat

1821    
1822Fix option syntax in dumpe2fs for explicit superblock and blocksize
1823parameters.  What was currently documented in the man page has been
1824broken for some time, due to getopt() implementation changes.  The
1825option sytax has been changed to one which is can be more portable
1826supported and which is consistent with the format for extended options
1827in mke2fs and tune2fs.  (Addresses Sourceforge Bug: #1830994)
1828

1937long.
1938
1939Mke2fs will now create new filesystems with 256 byte inodes and the
1940ext_attr feature flag by default.  This allows for much better future
1941compatibity with ext4 and speeds up extended attributes even on ext3
1942filesystems.
1943
1944Teach e2fsck to ignore certain "safe" filesystem features which are
1945set automatically by the kernel.  Having the kernel set features
1946automagically behind the user's back is a bad idea, and we should try
1947to break the kernel of this habit, especially for the newer ext4
1948feature flags.  But for now, we will try to avoid needless full checks
1949which can annoy users who are doing fresh installs.
1950
1951Add support in tune2fs and mke2fs for making a filesystem as being "ok
1952to be used with test kernel code".  This will be needed for using test
1953filesystems with the latest ext4 kernel code.
1954
1955Change e2fsck -fD so that it sorts non-htree directories by inode
1956numbers instead of by name, since that optimizes performances much
1957more significantly.  (Addresses-Sourceforge-Feature-Request: #532439)
1958
1959If e2image fills the disk, fix it so it exits right away instead of
1960spewing large numbers of error messages.

1962
1963If ftruncate64() is not available for resize2fs, let it use ftrucate()
1964instead, but have it check to see if the size would get truncated, and
1965skip calling ftruncate in that case.
1966
1967Add support for detecting HFS+ filesystems in the blkid library.
1968
1969Add supprt in the blkid library for ext4/ext4dev filesystems.
1970
1971Fix a bug in blkid where it could die on a floating point exception
1972when presented with a corrupt reiserfs image.
1973
1974Fix blkid's handling of ntfs UUID's so that leading zeros are printed
1975such that UUID string is a fixed length.
1976
1977Add sample python bindings for the uuid library to the contrib
1978directory.  (Addresses-Sourceforge-Patches: #778817)
1979
1980Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
1981will work with large files.  (Addresses Sourceforge Feature Request:
1982#1257500 and Sourceforge Support Request: #1253511)
1983    
1984Allow the debugfs 'undel' command to undelete an inode without linking
1985it to a specific destination directory, since this might require
1986allocating blocks that could overwrite some yet-to-be-recovered
1987deleted files.  (Addresses-Sourceforge-Feature-Request: #967141)

2023====================================
2024
2025Improve time-based UUID generation.  A new daemon uuidd, is started
2026automatically by libuuid if necessary.  This daemon is setuid to allow
2027updates to /var/lib/libuuid, so the clock sequence number can be
2028stored and so if the clock is set backwards, it can be detected.
2029(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:

2031
2032Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2033superblocks.  This avoids e2fsck from concluding that a full
2034filesystem check is required before backing up the superblock due to
2035changes in the feature flags.  (Addresses Debian Bug: #454926)
2036
2037Fix fsck to only treat the '#' character as a comment at the beginning
2038of the line in /etc/fstab.  Otherwise fstabs for the fuse filesystem
2039will cause fsck to issue an bogus warning message.

2077E2fsprogs 1.40.3 (December 5, 2007)
2078===================================
2079
2080Fix a potential security vulnerability where an untrusted filesystem
2081can be corrupted in such a way that a program using libext2fs will
2082allocate a buffer which is far too small.  This can lead to either a
2083crash or potentially a heap-based buffer overflow crash.  No known
2084exploits exist, but main concern is where an untrusted user who
2085possesses privileged access in a guest Xen environment could corrupt a
2086filesystem which is then accessed by the pygrub program, running as
2087root in the dom0 host environment, thus allowing the untrusted user to
2088gain privileged access in the host OS.  Thanks to the McAfee AVERT
2089Research group for reporting this issue.  (Addresses CVE-2007-5497.)
2090
2091Fix hueristics in blkid which could cause a disk without partitions to
2092be incorrectly skipped when a loopback device is present.  (Addresses
2093Red Hat Bugzilla #400321.)
2094
2095Fix e2image so that in raw mode it does not create an image file which
2096is one byte too large.
2097
2098Change mke2fs's usage message so it recommends the preferred -E option
2099instead of the deprecated -R option.
2100
2101Enhance the blkid library so it will recognize squashfs filesystems.
2102(Addresses Red Hat Bugzilla #305151.)
2103
2104Enhance e2fsck so it will force the backup superblocks to be backed up
2105if the filesystem is consistent and key constants have been changed
2106(i.e., by an on-line resize) or by e2fsck in the course of its
2107operations.
2108
2109Enhance blkid's detection of FAT filesystems; so that USB disks with
2110only a single bootable partition will not get missed.
2111
2112E2fsck will no longer mark a filesystem as invalid if it has time
2113errors (i.e., if superblock mount time or last write time is in the
2114future) and the user refuses to fix the problem.
2115
2116The Ubuntu init scripts don't properly set the system time correctly
2117from hardware clock if the hardware clock is configured to tick local
2118time instead of GMT time.  Work around this as best as we can by
2119providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2120be set on Ubuntu systems.  (Addresses Debian Bug #441093, and Ubuntu
2121Bug #131201.)
2122
2123Fix fsck to ignore /etc/fstab entries for bind mounts.  (Addresses Red
2124Hat Bugzilla #151533.)
2125
2126Fix e2fsck so that if the superblock is corrupt, but still looks
2127vaguely like an ext2/3/4 superblock, that it automatically tries to
2128fall back to the backup superblock, instead of failing with a hard
2129error.
2130
2131Make the e2fsprogs program more robust so that they will not crash
2132when opening a corrupt filesystem where s_inode_size is zero.
2133
2134Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2135arguments are detected as such and the parse error is reported to the
2136user.   (Addresses Debian Bug #435381.)
2137
2138Change e2fsck so it will not complain if a file has blocks reallocated
2139up to the next multiple of a system's page size.
2140
2141Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2142about (valid) filesystems where the inode table extends to the last
2143block of the block group.  (Addresses Red Hat Bugzilla #214765.)
2144
2145Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2146allocating inode tables for some relatively rare odd disk sizes.
2147(Addresses Red Hat Bugzilla #241767.)
2148
2149Add Catalan translation and update Dutch and Swedish translations
2150from the Translation Project.
2151
2152Fix big-endian byte-swapping bug in ext2fs_swap_inode_full().  We
2153still had an issue when trying to figure out whether we need to
2154byte-swap fast symlinks that contained extended attributes.
2155
2156Fixed spelling mistakes, typos, and otherwise clarified man pages.

2160Programmer's Notes:
2161-------------------
2162
2163Fix mke2fs tests to avoid needing any significant ^M (CR) characters
2164
2165Add "make check" to the RPM spec file
2166
2167Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2168works correctly when the prefix is not the root directory.
2169
2170Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2171clena up after themselves by deleting the test.img temporary file
2172after completing the test.
2173
2174Fixed a corner case bug ext2fs_unlink() when trying to delete the
2175first directory entry in a directory block and the last directory
2176entry in the previous directory block is not in use.  Fortunately
2177ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2178places where it is extremely unlikely to run into this corner case.
2179
2180Fix missing dependency which would cuase parallel builds to fail.
2181(Addresses Sourceforge Bug #1842331.)
2182
2183Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2184calling open(O_CREATE) with a missing mode parameter.
2185
2186Fix the test_ss.c in lib/ss so it can be used as an example
2187application program for the library as well as a regression test
2188suite.
2189
2190Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2191are properly passed back up through the call stack.
2192
2193E2fsprogs 1.40.2 (July 12, 2007)
2194================================
2195
2196A recent change to e2fsck_add_dir_info() to use tdb files to check
2197filesystems with a very large number of filesystems had a typo which
2198caused us to resize the wrong data structure.  This would cause a
2199array overrun leading to malloc pointer corruptions and segfaults.
2200Since we normally can very accurately predict how big the the dirinfo
2201array needs to be, this bug only got triggered on very badly corrupted
2202filesystems.
2203
2204Fix a bug in e2fsck which caused it to incorrectly salvange
2205directories when the last entry's rec_len is bogusly too big.  This
2206resulted in a nonsense filesystem corruption to be reported, and
2207required a second run of e2fsck to fully fix up the directory.
2208
2209Update tune2fs man page to include more discussion of reserved blocks
2210(Addresses Launchpad bug #47817)

2215
2216E2fsprogs 1.40.1 (July 7, 2007)
2217===============================
2218
2219Fix bug which could cause libblkid to loop forever.  When revalidating
2220a partition where there is obsolete information in /etc/blkid.tab, we
2221end up freeing a the type tag without clearing dev->bid_type, causing
2222blkid_verify() to loop forever.  (Addresses Debian Bug: #432052)
2223    
2224The Turkish translation has a bug in it where it has the translation
2225of "E@e '%Dn' in %p (%i)" to "E@E".  This causes @E to be expanded at
2226@E, recursively, forever, until the stack fills up and e2fsck core
2227dumps.  We fix this by making e2fsck stop @-expansions after a
2228recursive depth of 10, which is far more than we need.
2229(Addresses Sourceforge Bug: #1646081)
2230    
2231Compile the default mke2fs.conf into mke2fs program.  People are
2232getting surprised by mke2fs creating filesystems with different
2233defaults than earlier versions of mke2fs if mke2fs.conf is not
2234present.  So we now create a built in version of mke2fs.conf file
2235which is used by mke2fs if the /etc/mke2fs.conf is not present.
2236(Addresses SourceforgeBug: #1745818)
2237
2238Improve the config/parse_types.sh helper script.  Fix a potential
2239security problem if e2fsprogs is built as root (as Gentoo does!).  In
2240addition fix the script and how it is called from the configure script
2241so that it does the right thing when cross-compiling.  (Fixes Gentoo
2242bug: #146903)
2243    
2244Update Vietnamese, French, and Dutch PO files from the Translation
2245Project.  Also created a new e2fsprogs.pot file for translator.
2246    
2247Fix bogus strip permission errors when building under Debian.  When
2248building the e2fsprogs dpkg's, the dh_strip command emits a large
2249number of error messages caused by the permissions not being right.
2250So run dh_fixperms before running dh_strip.
2251
2252Programmer's Notes:
2253-------------------
2254
2255Add new function: profile_set_default().  This function sets the value
2256of the pseudo file "<default>".  If the file "<default>" had
2257previously been passed to profile_init(), then def_string parameter
2258will be parsed and used as the profile information for the "<default>"
2259file.
2260    
2261Fix mk_cmds's error reporting so that it is unambiguous that it is the
2262mk_cmds script which is generating the error.  (Obviates Gentoo patch:
2263e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2264    
2265Fix the test suite to use LC_ALL instead of LANG.  LC_ALL is the "high
2266priority" environment variable that overrides all others, where as
2267LANG is the lowest priorty environment variable.  If LC_ALL is set, it
2268doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2269the all the rest are set.  This will assure that the locale when
2270running the test suites is the "C" locale.  (Obviates Gentoo patch:
2271e2fsprogs-1.38-tests-locale.patch)
2272    
2273
2274E2fsprogs 1.40 (June 29, 2007)
2275==============================
2276
2277Fix divide by zero error in blkid's NTFS probing logic.
2278
2279Add new blkid -g option which causes the blkid cache to be garbage
2280collected.
2281
2282Fix a bug in libblkid which could cause the internal field bid_type to
2283become corrupted.  Fortunately bid_type isn't used much, and bid_label
2284and bid_uuid is only used by debugging code, so the impact of this bug
2285was very minor.
2286
2287Mke2fs will now store the RAID stride value when a filesystem is
2288created with a requested RAID stride, and then use it automatically in
2289resize2fs.
2290
2291Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2292isn't too big.  In some cases Lustre users have tried specifying an
2293inode size of 4096 bytes, while keeping an inode ratio of one inode
2294per 4096 bytes.  
2295
2296Improve sanity check in e2fsck's algorithm for finding a backup
2297superblock, so that it won't accidentally find a superblock that was
2298located in the journal, and then later reject it as being not a valid
2299backup superblock.
2300
2301Fix e2fsck get_size logic so that it will work with the Linux floppy
2302driver.  The Linux floppy driver is a bit different from the other
2303block device drivers, in that if the device has been opened with
2304O_EXCL, it disallows another open(), even if the second open() does
2305not have the O_EXCL flag.  (Addresses Debian Bug: #410569)
2306
2307Fix error checking of badblock's last-block and start-block arguments.
2308(Addresses Debian Bug: #416477)
2309
2310Fix e2fsck so that it doesn't overwrite the backup superblocks when
2311recovering a journal until the master superblock has been confirmed as
2312being sane.
2313
2314Change the blkid library to be much more paranoid about concluding
2315that a partition contains an NTFS filesystem, and fetch the UUID and
2316LABEL information from NTFS filesystems.  (Addresses Launchpad Bug:
2317#110138)
2318
2319Factor out the code which sets the default journal size and move it
2320into libext2fs.
2321
2322Enhance e2fsck so it will recreate the ext3 journal if the original
2323journal inode was cleared to due it being corrupt after finishing the
2324filesystem check.
2325
2326Fix e2fsck so that it updates the journal inode if it is corrupted and
2327the backup journal information from the superblock was successfully
2328used to recover the filesystem.
2329
2330Fix e2fsck so that it checks all of the blocks in the journal inode
2331for validity.  The original code only checked the direct blocks to
2332make sure the journal inode was sane.  Unfortunately, if some or all
2333of the indirect or doubly indirect blocks were corrupted, this would
2334not be caught.
2335
2336Add support in blkid to detect LUKS encrypted partitions.
2337
2338Add extra sanity checks for extended attributes in the case where the
2339size is zero but the offset is very large.
2340
2341Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
2342and ext2fs_get_next_inode_full().
2343
2344Clarify the copyright licenses used by the various libraries in
2345the top-level COPYING  file (Red Hat Bugzilla: 166058)
2346
2347Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
2348
2349Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
2350
2351Remove check in e2fsck which requires EA's in inodes to be sorted;
2352they don't need to be sorted, and e2fsck was previously wrongly
2353clearing unsorted EA's stored in the inode structure.
2354
2355Allow mke2fs or tune2fs to create a substantially larger journal (up
2356to 10,240,000 blocks).
2357
2358Fix MD superblock detection, and make sure the correct UUID is
2359reported from the MD superblock.
2360
2361Fix a signed vs. unsigned bug in debugfs.
2362
2363Enhance debugfs's date parser so that it accepts integer values.
2364
2365Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
2366file with multiply claimed blocks is hard linked. or not at all if the
2367root directory contains shared blocks
2368
2369Enhance debugfs so it can modify the block group descriptors using the
2370command set_block_group_descriptor.
2371
2372Improve e2fsck's reporting of I/O errors so it's clearer what it was
2373trying to do when an error happens
2374
2375Fix a bug in in how e2fsprogs byte swaps inodes containing fast
2376symlinks that have extended attributes.  (Addresses Red Hat Bugzilla:
2377#232663 and LTC Bugzilla: #27634)
2378
2379Fix potential file descriptor leak in ext2fs_get_device_size() in an
2380error case.
2381
2382Add libreadline.so.5 support to libss.
2383
2384Impove badblocks -n/-w exclusive usage message.
2385
2386Fix dump_unused segfault in debugfs when a filesystem is not open
2387
2388Fix memory leak in blkid library.  (Addresses Debian Bug: #413661)
2389

2392
2393Fix e2fsck to clear i_size for special devices with a bogus i_blocks
2394field on the first pass.
2395
2396Fix e2fsck to set the file type of the '..' entry when connecting
2397a directory to lost+found.  (Addresses Lustre Bug: #11645)
2398
2399Enhance e2fsck to recover directories whose modes field were corrupted
2400to look like special files.  This is probably only useful in
2401artificial test cases, but it will be useful if we ever do the "inodes
2402in directory" idea for ext4.
2403
2404Allow debugfs to dump (and rdump) > 2GB files.  (Addresses Debian Bug:
2405#412614)
2406
2407Fix resize2fs parsing of size parameter (in sector units).  This was
2408actually a bug in libe2p's parse_num_blocks() function.  When handling
2409the 's' suffix, it was ignoring the blocksize information passed in
2410from the caller and always interpreting the number in terms of a 1k
2411blocksize.  (Addresses Debian Bug: #408298)
2412
2413There was a floating point precision error which could cause e2fsck to
2414loop forever on really big filesystems with a large inode count.

2417Fix memory leak in ext2fs_write_new_inode()
2418
2419Add support for using a scratch files directory to reduce e2fsck's
2420emory utilization on really big filesystems.  This uses the TDB
2421library.  See the [scratch_files] section of the e2fsck.conf man page
2422for more details.
2423
2424Fixed type-punning bug which caused dumpe2fs to crash on the Arm
2425platform (Addresses Debian Bug: #397044)
2426
2427Add explanatory message to badblocks that -n and -w are mutually exclusive
2428(Addresses Debian Bug: #371869)
2429
2430Allow debugfs and dumpe2fs to support fs features under development.
2431
2432Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2433ext2fs_open() , which allows application to open filesystes with features
2434which are currently only partially supported by e2fsprogs.
2435
2436Allow unix_io to support offsets greater than 2G (Addresses
2437SourceForge Bug: #1547922)
2438
2439Fixed overflow and signed/unsigned problems caused by the number of
2440blocks or inodes exceeding 2**31 or being close to 2**32-1.
2441
2442Add support for unsigned directory hash calculations with hints in the
2443superblock to fix cross-architectural portability for htree
2444directories with filenames where the high 8th bit is set.  (Addresses
2445Debian: #389772)
2446
2447Fix resize2fs so that it gives user-intelligible error messages if the
2448filesystem or the kernel does not support on-line resizing.
2449(Addresses Debian Bug: #380548)
2450
2451Require mke2fs -F -F for really dangerous operations, since -F is
2452needed for less dangerous operations such as creating filesystems
2453images in regular files, or creating filesystems on whole block
2454devices.  These relatively innocuous usages should NOT be confused
2455with running mke2fs on an apparently-mounted or in-use filesystem.
2456
2457Allow the default inode size to be specified into the mke2fs.conf
2458file.
2459
2460Make the smallest default journal size is big enough so that on-line
2461resizing should always work.
2462
2463Fix silly spelling error in e2fsck.  (Addresses SourceForge bug:
2464#1531372)
2465
2466Fix debugfs coredump when lsdel is run without an open filesystem
2467(Addresses Debian Bug: #378335)
2468
2469Fix debugfs display bug us that bytes that have the high bit set are
2470displayed as "ec" instead of "ffffffec".
2471
2472Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
2473
2474Device mapper scanning wasn't working in the blkid library because the
2475pathnames had an extra "/dev" when they were being probed.
2476
2477Add GFS/GFS2 support to the blkid library.
2478
2479Fix blkid support of empty FAT filesystem labels.
2480
2481Avoid recursing forever (or for a long time) when the blkid library
2482searches for a device and there are symlinks to directories in /dev.
2483
2484Avoid unaligned halfword access in blkid when accessing FAT
2485superblocks, as this will cause Sparc/Solaris systems to throw a
2486SIGBUS error.
2487
2488The latest devmapper libraries requires pthreads, add -lpthreads to
2489the static link libraries for e2fsck.static if devmapper is enabled.
2490(Addresses Debian bug: #388718)
2491
2492Improve the (non-installed, for experts only) findsuper program by
2493printing the uuid and label from the superblocks, as well as the
2494starting and ending offsets of the filesystem given the information in
2495the superblock.  Omit by default printing superblocks that are likely
2496found in located in an ext3 journal unless an explicit -j option is
2497given.
2498
2499Updated Spanish, French and Dutch translations and added Catalan
2500translation.  (Addresses Debian bug: #411562)
2501
2502Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2503determining a partition's size, since binary searching to determine
2504the device doesn't work on FreeBSD.
2505
2506Documentation about UUID's is available in enough places, and it's
2507awkward to deal with debian-legal's insanities.  So I'm caving in the
2508"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2509don't have do the dfsg tarball.  Also remove the rule that only tried
2510to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2511e2fsprogs exclusively from Debian.  (Addresses Debian Bug: #407107)
2512
2513Fix the info-dir line so that the menu name does not contain a .info
2514prefix.  First of all, it's ugly, secondly, it causes the install-info
2515command to fail to remove the com_err info file from the
2516/usr/share/info/dir file when the comerr-dev package is removed and
2517purged.  (Addresses Debian Bug: #401711)
2518
2519Fixed spelling mistakes, typos, and otherwise clarified man pages.

2526
2527Programmer's notes:
2528-------------------
2529
2530E2fsck now supports the %It expansion when printing a problem report.
2531It will print the type of the inode in the problem context.
2532
2533Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
2534(Addresses Sourceforge Bug: #1565561)
2535
2536Remove unused variables and other lint/gcc -Wall cleanups
2537
2538Add check to ext2fs_get_device_size() so it will return EFBIG for for
2539filesystems contained in regular files where the filesystem image size
2540is returned by stat64().
2541
2542Set local environment variables to C so mk_cmds and compile_et always
2543work.  (Addresses SourceForge Bug: #1532177)
2544
2545Added the 64-bit byte swapping function ext2fs_swab64().
2546
2547Added two new helper functions to prevent 2**31/2**32-1 overflow
2548problems: ext2fs_div_ceil() and e2p_percent().
2549
2550Create new ext2fs library inline functions ext2fs_group_first_block()
2551and ext2fs_group_last_block() in order to calculate the starting and
2552ending blocks in a block group.
2553
2554Create the generated files read-only to remind developers not to edit them.
2555
2556Add support for autoconf 2.60 (with backwards compatibility for older
2557versions of autoconf).
2558
2559Added an "make rpm" target to top-level Makefile
2560
2561Added various FreeBSD portability fixes.
2562
2563Exclude mercurial files from the RPM build tree to speed up copy/build.
2564
2565Use root_sysconfdir to define the locations of mke2fs.conf and
2566e2fsck.conf instead of using a hard-coded /etc pathname.
2567
2568Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2569
2570Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2571
2572If diff -u is supported, use it to report test failures.
2573
2574Updates/improvements to RPM spec file
2575
2576Add on-disk format definitions for the following new features:
2577EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2578EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2579EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2580
2581Add a new make target "checked-failed" in the tests directory which
2582reruns any failed tests
2583
2584Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2585
2586Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2587pointer dereferences, memory leaks, etc.  None were security-criticial
2588problems.
2589
2590Fix up usage and decrement error messages in the test_icount program
2591
2592Add debugging code to the com_err library; if the environment variable
2593COMERR_DEBUG is set to 1, print out debugging messages as error tables
2594are added and removed from the com_err library.  If the
2595COMERR_DEBUG_FILE environment variable is set (and the process is not
2596setuid) the debugging messages may be redirected to a file.
2597
2598Change all of the e2fsprogs programs to use the newer add_error_table()
2599and remove_error_table() interfaces instead of the much older
2600initialize_*_error_table() function.
2601
2602Add TDB support into the ext2fs library.  This allows us to have a
2603guaranteed library we can count on always being present so we can
2604store data in an on-disk database.
2605
2606Add support for using TDB to store the icount data, so we don't run out
2607of memory when checking really large filesystems.
2608
2609Change the regression test suite so that it skips empty test directories.
2610
2611Define the l_i_iversion field in ext2_inode.  The l_i_version field is
2612now defined from the old l_i_reserved1 field in the ext2 inode.  This
2613field will be used to store high 32 bits of the 64-bit inode version
2614number.
2615
2616Add Makefile production rule for e2fsprogs.spec in case it gets
2617deleted.
2618
2619Add new function profile_get_uint() to allow for a clean way to fetch
2620unsigned integers from the context.
2621
2622Add test to make sure the ext2 superblock structure is 1024 bytes.
2623
2624Fix typo in name of f_dup4 regression test
2625
2626Add new function blkid_gc_cache() which performs a garbage collection
2627pass on the /etc/blkid.tab file.
2628
2629The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY.  In
2630general, only e2fsck (after the filesystem is clean), tune2fs, and
2631resize2fs should change the backup superblocks by default.  Most
2632callers of ext2fs_open() should not be touching any superblock fields
2633which require the backups to be touched.
2634
2635Add new function to libext2fs, ext2fs_default_journal_size(), which
2636returns the default journal size.
2637
2638
2639E2fsprogs 1.39 (May 29, 2006) 
2640=============================
2641
2642Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2643between 2**31 and 2**32 blocks.
2644
2645Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2646configure the filesystem features, blocksize, and inode_ratio for
2647different filesystem types.
2648
2649Mke2fs will now create filesystems hash trees and on-line resizing
2650enabled by default, based on the new /etc/mke2fs.conf file.
2651
2652The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2653filesystem device node in exclusive mode to prevent accidents by
2654system administrators.  In the case of resize2fs and mke2fs, it will
2655only use exclusive mode if the filesystem is not mounted.
2656
2657Fixed a bug in mke2fs which caused it to to fail when creating the
2658resize inode for large filesystems.  (Addresses Debian Bug #346580)
2659
2660When allocating space for the RAID filesystems with the stride
2661parameter, mke2fs will now place each portion of the group's inode
2662table right up after the superblock (if present) in order to minimize
2663fragmentation of the freespace.
2664
2665Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2666efficiently by writing the inode and block bitmaps in one pass, thus
2667reducing the number of disk seeks required.
2668
2669Add support for on-line resizing to resize2fs.
2670
2671Fix blkid library so that logic to determine whether or not a device's
2672cached information in /etc/blkid.tab needs to be verified or not
2673doesn't get confused by a system clock which is insane (for example,
2674if the battery is dead on a Macintosh running PPC Linux.  (Addresses
2675Red Hat Bug: #182188)
2676
2677The blkid library will now store the UUID of the external journal used
2678by ext3 filesystems, so that in the future, the userspace mount binary
2679can use this to find the location of the external journal and pass
2680this information to the kernel.
2681
2682E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2683control how various options should be handled.  See the e2fsck.conf
2684man page for more details.   (Addresses Debian Bug: #150295)
2685
2686E2fsck now prints an explanatory message when delaying a filesystem
2687check when the system is running on battery.  (Addresses Debian Bug:
2688#350306)
2689
2690E2fsck will detect if the superblock's last mount field or last write
2691field is in the future, and offer to fix if so.  (Addresses Debian Bug
2692#327580) These problems will be fixed automatically in preen mode
2693since Debian's boot sequence bogusly doesn't set the time correctly
2694until potentially very late in the bootup process, and this can cause
2695false positives which will cause users' systems to fail to boot.
2696(Addresses Debian Bugs #343662 and #343645)
2697
2698E2fsck now checks to see if the superblock hint for the location of
2699the external journal is incorrect, and if so, offer to update it.
2700(Addresses Debian Bug: #355644)
2701
2702Fix e2fsck from segfaulting on disconnected inodes that contain one or
2703more extended attributes.  (Addresses Debian Bug: #316736, #318463)
2704
2705E2fsck will stop and print a warning if the user tries running a
2706read/write badblocks test on a read-only mounted root filesystem.
2707
2708Fix a memory leak in e2fsck's error paths.  (Thanks to Michael
2709C. Thompson for pointing these out; they were originally found using
2710Coverity.)
2711
2712When resizing a file containing a filesystem, resize2fs will expand or
2713truncate a file as necessary.  (Addresses Debian Bug: #271607)
2714
2715Resize2fs will now automatically determine the RAID stride parameter that
2716had been used to create the filesystem, and use that for newly created
2717block groups.   The RAID stride parameter may also be manually specified
2718on the command line using the new -S option to resize2fs.
2719
2720Fix mke2fs so that it correctly creates external journals on
2721big-endian machines (such as a S/390).  
2722
2723Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2724fail to print out the journal or hash seed UUID.  (Thanks to Guillaume
2725Chambraud for pointing this out.)
2726
2727Dumpe2fs will now print the size of the journal (if present).
2728
2729Fix debugfs's set_inode_field command so it can properly set the frag,
2730fsize, uid_high, gid_high, and author fields in the inode instead of
2731silently failing, and so that setting the i_size actually sets i_size
2732correctly.
2733
2734Add a new debugfs command, set_current_time, which sets fs->now so
2735that regression test suites can repeatedly modify the filesystem's
2736last_write fields.
2737
2738Fix a bug in debugfs's icheck which would incorrectly report the owner
2739of an extended attribute block.
2740
2741Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2742print a usage message when an illegal option character is given.
2743
2744Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2745so it won't core dump.  (Addresses SourceForge bug #1424311)
2746
2747Fix mklost+found so that it creates a full-sized directory on
2748filesystems with larger block sizes.
2749
2750Fix a file descriptor leak in blkid library.
2751
2752Fix a display bug in "badblocks -sv" so that the done message properly
2753clears the block number at the end of the test.  (Addresses Debian Bug
2754#322231)
2755
2756Allow fractional percentages to the -m option in mke2fs and tune2fs
2757(Addresses Debian Bug: #80205)
2758
2759Use fstat/fstat64 in getsize.c if the the target is a regular file,
2760instead of attempting to do a binary search.  Fix some fd leaks in
2761error cases.
2762
2763Add support for device mapper library to the blkid library to ensure
2764that the "best" (i.e., leaf) device is probed by the blkid library.
2765
2766Fix the blkid library so that it notices when an ext2 filesystem is
2767upgraded to ext3.
2768
2769Improve the blkid's library VFAT/FAT detection; it now understands
2770labels stored in the root directory, and is more paranoid about
2771checking the FAT superblock values.
2772
2773Fixed a fd leak in the uuid library which was causing problems for the
2774LVM tools.  (Addresses Debian Bug: #345832)
2775
2776Add support for the reiser4 and software suspend partitions to the
2777blkid library.  Also add support for extract the label from iso9660
2778filesystems.
2779
2780Fix a compile_et bug which miscount the number of error messages if
2781continuations are used in the .et file.
2782
2783Add extra sanity checks to protect users from unusual cirucmstances
2784where /etc/mtab may not be sane, by checking to see if the device is
2785reported busy (works on Linux 2.6) kernels.  (Addresses Debian Bug
2786#319002)
2787
2788Updated French, Dutch, Polish, and Swedish translations.  (Addresses Debian
2789Bug: #343149, #341911, #300871, #316604, #316782, #330789)
2790
2791Fix use-after-free bug in e2fsck when finishing up the use of the
2792e2fsck context structure.
2793
2794Fixed spelling mistakes, typos, and otherwise clarified man pages and
2795documentation.  (Addresses Debian Bugs: #329859, #322188, #316811,

2803
2804
2805Programmer's notes:
2806-------------------
2807
2808Update config.guess and config.sub to latest version (2006-02-23) from
2809FSF.
2810
2811Fix asm_types.h type conflicts on AMD 64 platforms.  (Addresses Debian
2812Bugs: #360661, #360317)
2813
2814Fixed the Makefile so that they work correctly on newer versions of
2815GNU make (i.e., 3.81).
2816
2817Add valgrind support to the regression test suites, and eliminate
2818false positives from valgrind.
2819
2820Add a regression test suite for the blkid library.
2821
2822Fix a fencepost error in resize2fs caught by valgrind.  
2823
2824Fix compiler warnings about missing memcpy prototypes.
2825
2826We no longer have the sparc assembly code in the header file any more,
2827so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc.  This would
2828break compiles on the sparc architectures when using gcc.
2829
2830In the libext2fs library, add the new field fs->now which if non-zero
2831is used instead of the system time when setting various filesystem
2832fields (last modified time, last write time, etc.)
2833
2834Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2835ext2fs.h which is needed since the inline functions use memcpy().
2836(Addresses Sourceforge Bug #1251062)
2837
2838Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2839the build system when building files in the util directory which are
2840needed during the build process.  This avoids potential problems when
2841cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2842are not recognized as valid by the host compiler.  (Addresses
2843Sourceforge Bug #1261547)
2844
2845Clean up the blkid library by making the superblock and generic i/o
2846functions to be more generic.  Clean up interface to the probe
2847function, and fix memory leak.  Finallly, remove an unneeded reference
2848to probe.h in the lib/blkid/resolve.c
2849
2850Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2851of invalid block #'s.
2852
2853The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2854indicate that the the function read/writes the memory location.
2855
2856Fix various gcc -Wall complaints.
2857
2858Add a dependency to make sure that the subdirectories are created
2859before creating all of the object files, in order to address parallel
2860build problem in the library Makefiles.  (Addresses Sourceforge Bug:
2861#1261553)
2862
2863Add $(LDFLAGS) to the command line argument when generating an ELF or
2864Solaris shared library, to allow cross-compile and other builds that
2865might need to specify -L paths to needed libraries.  (Addresses
2866Sourceforge Bug #1261549)
2867
2868Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2869intended for testing purposes.  It allows an ext2/ext3 developer to
2870create very large filesystems using sparse files where most of the
2871block groups are not initialized and so do not require much disk
2872space.  Eventually it could be used as a way of speeding up mke2fs and
2873e2fsck for large filesystem, but that would be best done by adding an
2874RO_COMPAT extension to the filesystem to allow the inode table to be
2875lazily initialized on a per-block basis, instead of being entirely
2876initialized or entirely unused on a per-blockgroup basis.
2877

28792.0.35 systems.
2880
2881Make test scripts more robust against locale-related environment variables
2882
2883Fix type warning problem with sizeof() in ext2fs_open2().
2884
2885Fix type warning problem with time_t in debugfs.
2886
2887
2888E2fsprogs 1.38 (June 30, 2005)
2889==============================
2890
2891Fix blkid's test programs (built with "make check") compile correctly
2892even without "configure --enable-blkid-debug".
2893
2894Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2895type aliasing rules on newer gcc compilers.  (Addresses Red Hat
2896Bugzilla ##161183.)
2897
2898Fix com_err library to make it more compatible with recent changes
2899made to the com_err library in MIT Kerberos V5 version 1.4.
2900(Addresses Sourcefroge Bug #1150146)
2901
2902General cleanup of messages printed by e2fsprogs programs for grammar,
2903consistency, and to make life easier for translators.  Fixed a few
2904strings containing English that had not been marked as needing
2905translations.  Removed strings that do not need to be translated, to
2906make life easier for translators.
2907
2908Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2909test to see if a device appears to be in use instead of just relying
2910on /proc/mounts and /etc/mtab.  (Addresses Debian Bug #308594).
2911
2912Fix portability problem in the filefrag program affecting platforms
2913where the size of an integer is smaller than the size of a long.
2914(Addresses Debian Bug #309655)
2915
2916Mke2fs will now use a larger journal by default for filesystems
2917greater than 4GB.  (128 MB instead of 32MB).
2918
2919Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2920unless forced.  This is to avoid signed vs. unsigned kernel bugs in
2921block numbers that still need to be fixed.
2922
2923The blkid program has a new option which will more efficiently search
2924for device when it is known (or expected) that only one matching
2925device will be found in the system, such as when doing a lookup by
2926UUID.
2927
2928Debian's e2fsprogs-specific initrd fragment will avoid including
2929unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2930and LD_LIBRARY_PATH, and filtering out libraries found in
2931/etc/ld.so.preload.  (Addresses Debian Bug: #304003)
2932
2933Fixed a potential portability issue in the blkid programs for
2934architectures where the char type is unsigned.  (Addresses Sourceforge
2935Bug: #1180585)
2936
2937Fix a bug in filefrag so that it doesn't falsely count an extra
2938discontinuity when the first block found is an indirect block.
2939(Addresses Debian Bug #307607).
2940
2941Fix blkid's recognition of cramfs filesystems, and enhance it to be
2942able to handle cramfs labels.
2943
2944Fix debugfs's stat command to not core dump when a filesystem is not
2945open.
2946
2947Fix e2fsck's handling of error conditions caused by the resize inode
2948claiming blocks that are also used by other inodes, a filesystem
2949corruption which was commonly caused by a bug in Fedora Core 3's
2950resize2fs program.
2951
2952Fixed bug in filefrag which caused it to fail on non-ext2/3
2953filesystems.  (Addresses Debian Bug: #303509)
2954
2955If the superblock last mount time indicates that the system clock may
2956not be accurate, then e2fsck will omit checking inodes' deletion time
2957field for indications of a potential corrupted orphaned inode list.
2958(Previously e2fsck only ommited these LOW_DTIME checks when the
2959superblock's last write time looked insane.)
2960
2961Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
2962(Addresses Debian bug #302200)
2963
2964Make the blkid library more paranoid about being run from setgid
2965programs, and to use __secure_getenv() from libc if it is available.
2966
2967Fixed spelling mistakes, typos, and otherwise clarified man pages.
2968(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
2969and Sourceforge Bug: #1189803)
2970
2971Updated and fixed translations.
2972
2973Fixed various Debian packaging issues --- see debian/changelog for
2974details.
2975
2976Programmer's notes:
2977-------------------
2978
2979Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2980changed to take an unsigned int for the bit number.  Negative bit
2981numbers were never allowed (and didn't make any sense), so this should
2982be a safe change.  This is needed to allow safe use of block numbers
2983greater than or equal to 2**31.
2984
2985The compile_et program will avoid recreating generated foo_err.c and
2986foo_err.h files if no changes are necessary.  The compile_et program
2987will also atomically replace these files to avoid a potential parallel
2988build race problem on SMP systems.  (Addresses Sourceforge Bug:
2989#1157933)
2990
2991Added a new function to the blkid library, blkid_probe_all_new(),
2992which only probes newly added disk devices, and change
2993blkid_find_dev_with_tag() to use this function so that when a
2994requested tag is not found, devices that were previously not checked
2995are searched before searching all devices in the system.
2996
2997Added new functions to the blkid library, blkid_dev_set_search() and
2998blkid_dev_has_tag().
2999
3000E2fsck's problem strings can now use @m and @n as abbrevations for
3001"multiply-claimed" and "invalid", respectively.
3002
3003The e2fsprog.pot file now has an explanation of how the @-expansion
3004and %-expansion works, and strings in e2fsck/problem.c which contain @
3005characters now have comments in e2fsprogs.pot with the @-expansion to
3006make life easier for translators.
3007
3008Fixed missing return values in the ext2fs library which could cause it
3009to return random garbage in certain error conditions.
3010
3011Allow the current time to be overriden via the E2FSCK_TIME environment
3012variable for use in regression tests.
3013
3014The test scrpit driver program now exits with a non-zero status if
3015there any of its test that it ran failed.
3016
3017Fixed problems with parabuilds on SMP systems.  (Addresses Sourceforge
3018Bug: #1157933)
3019
3020Fixed "make check" so that it compiles correctly even when e2fsprogs'
3021header files have not be installed in the system include directories.
3022(Addresses Sourceforge Bug: #1180572)
3023
3024Fixed gcc -Wall nits.
3025
3026
3027E2fsprogs 1.37 (March 21, 2005)
3028===============================
3029
3030Add support for checking the validity of Extended Attributes stored in
3031inodes to e2fsck.
3032
3033Add support for dumping the contents of large inodes to debugfs,
3034including the extended attributes stored in inodes.
3035
3036Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3037when we create a new inode we make sure that the extra information in
3038the inode (any extra fields in a large inode and any ea-in-inode
3039information) is initialized correctly.  This can take place when
3040mke2fs creates the root and lost+found directory, when e2fsck creates
3041a new root inode or a new lost+found directory, and when the user uses
3042the debugfs write, mknod, or mkdir commands.  Otherwise, the newly
3043create inode could inherit garbage (or old EA information) from a
3044previously deleted inode.
3045
3046Fixed a bug in e2fsck so it would notice if a file with an extended
3047attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3048to zero.
3049
3050Added support to filefrag to detect files which are using the new
3051experimental file extents format, and use the non-ext2 algorithm in
3052that case.  Fixed a bug to avoid reporting a false discontinuity if
3053there is one or more unallocated blocks at the beginning of a file.
3054
3055Duplicated a check for noticing whether or not the number of blocks
3056(given a certain blocksize) is greater than 2**32 when the
3057BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size().  This
3058allows mke2fs to automatically use a larger blocksize when creating a
3059filesystem on a very large device when run on systems that do not
3060support BLKGETSIZE64.
3061
3062Fix the I18N build which was broken in e2fsprogs 1.36 because the
3063build system had been switched to treat the .gmo files as shipped
3064files (for backwards compatibility with systems that have older GNU
3065I18N tools installed), but the gen_tarball.in script was still
3066removing the .gmo files from the official source distribution.
3067
3068Fixed various Debian packaging issues --- see debian/changelog for
3069details.  (Addresses Debian Bugs ##296769, #299341)
3070
3071Programmer's notes:
3072-------------------
3073
3074Added new functions to the e2p library which convert between a string
3075and os_type: e2p_os2string() and e2p_string2os(), and used them to
3076make the generated binaries more compact.
3077
3078Fixed a compile-time error on Darwin systems.
3079
3080Cleaned up the lib/ext2fs Makefile slightly.
3081
3082
3083E2fsprogs 1.36 (February 4, 2005)
3084=================================
3085
3086All of the patches that were applied to Fedore Core 3's
3087e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3088lot of bug fixes first.  Users of Fedora Core 3 are strongly
3089encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3090
3091Add support for filesystem with the online resizing via resize inode
3092feature.  Fixed numerous bugs from the Fedora patches.  The Fedora
3093patches also didn't bother to do any consistency checking on the
3094resize inode, or add any tests to the regression test suite.  The "-R
3095resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3096being listed in mke2fs's usage message.  All of these shortcomings
3097have been corrected.
3098
3099E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3100program.  In order to do this, the user must run the commands:
3101
3102	debugfs -w /dev/hdXXX -R "features ^resize_inode"
3103        e2fsck -f /dev/hdXXX
3104
3105Optionally, the ext2prepare command can be used to re-enable online
3106resizing after the filesystem has been fixed.
3107
3108The fsck program will now accept an optional filedescriptor argument
3109to the -C option.  (The Fedora version of this patch would sometimes
3110cause fsck to ignore a parameter on fsck's command line in some rare
3111cases, sigh.)
3112
3113Make sure e2fsprogs doesn't write garbage into the reserved portion of
3114large inodes.
3115
3116Make sure resize2fs releases the blocks belonging to the old inode
3117table blocks when moving the inode table.  (Addresses Debian Bug:
3118#290894)
3119
3120Skip the r_resize_inode test if resize2fs is not compiled (due to
3121configure --disable-resizer)
3122
3123E2fsck now checks the summary filesystem accounting information, and
3124if any of the information is obviously wrong, it will force a full
3125filesystem check.  (Addresses Debian Bug #291571)
3126
3127Fix e2fsck to not complain when the resize_inode feature is enabled,
3128s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3129the resize inode.
3130
3131Fix e2fsck to note delete symlinks that contain an extended attribute
3132after the ext_attr feature flag has been cleared.  (Addresses Red Hat
3133Bugzilla #146284).
3134
3135Add new utility program, copy_sparse.c, which is very useful
3136for dealing with large sparse files (such as e2image files).
3137
3138Add support for jnl_blocks[] for debugfs's set_super_value.
3139
3140Fix filefrag so that it works correctly with sparse files.
3141
3142Filefrag -v will print first and last blocks.
3143
3144Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3145and dumpe2fs.
3146
3147Add mke2fs support so that it can support filesystems larger than 4TB
3148automatically, by retrying with a 4k blocksize if the device size is
3149too big to be expressed using a 1k blocksize.  (Addresses Sourceforge
3150bug #1106631)
3151
3152Change blkid to test for NTFS first because Windows sometimes doesn't
3153clear enough of the parition to confuse the probing routines into
3154thinking the old filesystem type is still valid.  (Addresses Debian
3155Bug #291990)
3156
3157Add support for swap partition label and uuid's in the blkid library.
3158
3159Add support to the blkid library to recognize Oracle ASM volumes.
3160
3161Make blkid -t display all devices that match the specified criteria,
3162not just the first one, and work more consistently when the blkid
3163cache file is not available or set to /dev/null.  (Addresses Debian
3164Bug #290530 and #292425)
3165
3166Badblocks will now correctly display block numbers greater than
3167999,999,999 in its progress display.
3168
3169The tune2fs program will not allow the user from setting a ridiculous
3170number of reserved blocks which would cause e2fsck to assume the
3171superblock was corrupt.  E2fsck's standards for what is a ridiculous
3172number of reserved block has also been relaxed to 50% of the blocks in
3173the filesystem.
3174
3175The blkid library will return vfat in preference to msdos, and ext3 in
3176preference to ext2 (if the journalling flag is set) so that mount will
3177do the right thing.  (Addresses Debian bug #287455)
3178  
3179Mke2fs will now use the -E option for extended options; the old -R
3180(raid options) option is still accepted for backwards compatibility.
3181Fix a double-free problem in resize2fs.  (Red Hat Bugzilla #132707)
3182
3183Mke2fs will now accept a size in megabytes, gigabytes, and other units
3184(via "32m" or "4g" on the command line) if the user finds this more
3185convenient than specifying a block count.
3186
3187Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3188cache conherency problem.
3189
3190Debugfs now supports a new command, set_inode_field, which allows a
3191user to manually set a specific inode field more conveniently, as well
3192as set entries in the indirect block map.
3193
3194Debugfs's set_super_value command has been enhanced so that the user
3195can set most superblock fields, including the date/time fields and
3196some of the more newsly added superblock fields.
3197
3198E2fsprogs programs now accept an offset to be passed to the file
3199specifiers, via the syntax: "/tmp/test.img?offset=1024".
3200
3201E2fsprogs programs will now accept blocksizes up to 65536; kernel
3202support on the x86 doesn't exist for now, but it can be useful on
3203other architectures with page sizes greater than 4k.  There are 2.6
3204kernel patches out there which enable this, but they are of this
3205writing still experimental.
3206
3207The e2image command now takes the -s option which will scramble
3208directory entries for raw image files.
3209
3210Fix a file descriptor leak in the filefrag program.
3211
3212Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3213present.
3214
3215Fix bug in debugfs where kill_file would lead to errors when deleting
3216devices and symlinks.  (Sourceforge Bugs #954741 and #957244)
3217
3218Fix bug in the blkid library when detecting the ocfs1 filesystem 
3219
3220Remove obsolete EVMS 1.x and a.out DLL support.
3221
3222E2fsck will attempt to recover from a journal containing illegal blocks.
3223
3224Fixed two potential ordering constraint problems in e2fsck which might
3225cause the filesystem to be corrupted if e2fsck is interrupted during a
3226(extremely narrow) race window.  Thanks to Junfeng Yang from the
3227Stanford Metacompilation group for pointing this out.
3228
3229Fixed bug in e2fsck where it would not accurately detect whether or
3230not the system is running on adaptor if the ACPI device representing
3231the AC adapter didn't correspond to the what was used on IBM
3232Thinkpads.
3233
3234Change e2fsck to accept directories greater than 32MB.
3235
3236Fix e2fsck so that a checkinterval of zero disables a time-based check
3237of the filesystem.
3238
3239Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3240to the PAGER environment variable.  (Addresses Debian Bug #239547)
3241
3242Tune2fs will not mark rewrite the superblock if the feature bitmasks 
3243are not modified.
3244
3245The debugfs program will set the filetype information when creating a
3246link.
3247
3248Add debugfs -d option to use a separate source of data blocks when
3249reading from an e2image file.
3250
3251Add e2image -I option which allows the e2image metadata to be
3252installed into a filesystem.
3253
3254Fixed bug in the badblocks program which caused "done" to always
3255appear in english even when a translation was available.  (Addresses
3256Debian Bug #252836)
3257
3258The blkid program has a new option -o which controls the output format
3259of the blkid program; this is makes blkid more convenient to use in
3260shell scripts.
3261
3262Fix a minor bug in uuid library, which was not using the full 14 bits
3263of clock sequence when generating UUID's.
3264
3265Fix a Y8.8888K problem in the uuid library.
3266
3267Logsave now creates a new session id for itself to avoid getting
3268killed by init whan transitioning between init levels.
3269
3270Change the licensing of the UUID library to be the 3-clause BSD-style
3271license; this allows Apple to use the uuid library in Darwin.
3272
3273Add ocfs and ocfs2 probe support into the blkid library.
3274
3275Fix a memory and file descriptor leak in the blkid library.
3276
3277The blkid library will revalidate the device if the system time is
3278earlier than last verification time of the device, since that
3279indicates that the system time is probably nottrustworthy.
3280
3281The blkid library will override the default location of the blkid.tab
3282file by the BLKID_FILE environment variable, if it is available.
3283
3284Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3285
3286Add various portability fixes for lame new versions of glibc, Darwin
3287and GNU/KFreeBSD, as well as removing XSI:ism's.  (Addresses Debian
3288Bugs #239934, #264630, #269044, #255589, #289133)
3289
3290Add support for Windows 9x/NT under Cygwin.
3291
3292Updated and clarified various man pages.  (Addresses Debian Bugs #236383,
3293	#241940, #238741, #242995, #256669, #268148, #256760, #273679)
3294
3295Updated and fixed translations.   (Addresses Debian bugs #244105, #262836)
3296
3297Update the rpm spec files so that it works better with Fedora core 2
3298and RH9.
3299
3300Fixed various Debian packaging issues (see debian/changelog).  In
3301particular, fixed the Debian initrd scripts.  (#241183, #248050,
3302#253595, #247775)
3303
3304
3305Programmer's notes: 
3306-------------------
3307
3308Fixed various gcc -Wall warnings.
3309
3310The uuid library now has new functions uuid_unparse_upper() and
3311uuid_unparse_lower() which forces the case of the hex digits to be
3312upper case, or lower case.
3313
3314The build process has been speeded up by enhancing the subst program
3315to update the modtime on the generated files even when the generated
3316file hasn't changed.
3317
3318The uuid library now uses C99 stdint.h types instead of custom types.
3319
3320Updated config.guess and config.sub with newer versions from the FSF.
3321
3322Removed out of date .cvsignore files from the source distribution.
3323
3324The ext2fs_unlink() function will return an error if both the name and
3325inode number are unspecified, to avoid doing something surprising
3326(such as unconditionally deleting the first directory entry).
3327Directory entries are now deleted by coalescing them with the previous
3328directory entry if possible, to avoid directory fragmentation.  This
3329is not an issue with the e2fsprogs suite, but may be a problem for
3330some of the users of libext2fs, such as e2tools.
3331
3332Add support for version numbers of the form "1.36-rc1".
3333
3334Fix build of mke2fs.static.
3335
3336Add basic ext2fs library support for large (EA in inode) inodes.
3337
3338The test_io mechanism can now abort after n reads or writes to a
3339particular block.  The block is specified by TEST_IO_BLOCK environment
3340variable, and the read/write count by the TEST_IO_READ_ABORT and
3341TEST_IO_WRITE_ABORT environment variables.  The block data is now only
3342dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3343
3344UUID_DEFINE() in the uuid library now creates a static variable, with
3345__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3346be used in header files.
3347
3348Add support for the install-strip and install-shlibs-strip targets, as
3349suggested by the GNU coding guielines.  "make install" no longer
3350strips the binaries which are installed.
3351
3352Remove support for the --enable-old-bitops configure option which was
3353only for very old sparc systems.
3354
3355Remove support for --enable-clear-htree; this was only needed during
3356the early development of the htree patch.
3357
3358Use Linux-kernel-style makefile output so it is easier to see compiler
3359warnings.
3360
3361Update gettext files to version 0.14.1.
3362
3363Update to use autoconf 2.5x.
3364
3365Improved support for compiling e2fsprogs under dietlibc.
3366
3367Make e2fsprogs portable to Solaris and FreeBSD systems.
3368
3369Add blkid_verify(), blkid_get_library_version(), and
3370blkid_parse_version_string() functions to the blkid library.
3371
3372Add pkg-config files for e2fsprogs's libraries.
3373
3374Fix "make uninstall" to so that it removes everything that is installed.
3375
3376Add a configure --enable-maintainer-mode option which enables the
3377makefile rules to rebuild the configure script from configure.in, and
3378to reubuild the .gmo files in po directory.
3379
3380Drop the sparc assembly bitwise operations; it's less efficient
3381than the GCC 3.4 compile code and triggers compiler warnings on
3382sparc64.  Thanks to Matthias Andree for his analysis and suggestions.

3385
3386E2fsprogs 1.35 (February 28, 2004) 
3387==================================
3388
3389E2fsck has a new -k option, which in conjunction with the -c options,
3390preserves the existing badblocks list.
3391
3392Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3393
3394E2fsprogs will now deal correctly with symlinks that contain
3395extended attribute information, which can be created using SE Linux.
3396(Addresses Debian Bug #232328)
3397                                                                               
3398Remove a double longjump into an invalid stack frame bug in e2fsck.
3399(This was during an abort sequence, which normally worked on Linux and
3400caused a core dump on other operating systems.)
3401
3402Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3403(the NLS library will replace "" with the .po header information).
3404 
3405Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3406dump due to a division by zero error.  (Addresses Debian bug #207082)
3407
3408Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3409when reconnecting a directory requires creating a lost+found
3410directory.  (Addresses Debian bug #219640).
3411
3412Fixed a bug where e2fsck would bomb out if a journal needed to be
3413replayed when using an alternate superblock.
3414 
3415E2fsck will give an extra grace period before actually forcing a check
3416if the laptop is running on battery.  The next time fsck runs while
3417the system is on the AC mains, or after the grace period is exceeded,
3418the filesystem will be checked.  (Addresses Debian bug #205177)
3419
3420E2fsck will inform the user when there are 5 or fewer mounts before a
3421filesystem check will be forced.  (Addresses Debian bug #157194)
3422
3423Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3424We now correctly handle the case where there is an overlap between a
3425block group descriptor or a superblock and a bad block indirect block.
3426In the case where the indirect block is corrupted, we now suggest
3427"e2fsck -c".
3428
3429Fix byte swap bugs in e2fsck that caused the journal backup location 
3430in the superblock and symlinks created by SE Linux to be cleared
3431by e2fsck on big-endian machines.  (Addresses Debian bug #228723)
3432
3433E2fsck -c now replaces the current list of bad blocks with the ones
3434found by badblocks.
3435
3436Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3437non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3438
3439Fix a potential bug in e2fsck which could cause it to core dump when
3440trying to print the location of the backup superblock.
3441
3442Protect against a potential core dump in e2fsck when printing a
3443message about backup superblocks.
3444
3445Add support for backing up the journal inode location in the
3446superblock.  E2fsck will automatically save the journal information in
3447the superblock if it is not there already, and will use it if the
3448journal inode appears to be corrupted.  ext2fs_add_journal_inode()
3449will also save the backup information, so that new filesystems created
3450by mke2fs and filesystems that have journals added via tune2fs will
3451also have journal location written to the superblock as well.
3452Debugfs's logdump command has been enhanced so that it can use the
3453journal information in the superblock.
3454
3455E2fsck will now update all superblocks when moving the journal inode.
3456  
3457Shrink the size of the e2fsck executable by moving some initialized
3458variables to the BSS segment.
3459
3460E2fsck will avoid printing the ^A and ^B characters which bracket the
3461progress bar when stdout and stdin are a tty device instead of a pipe
3462to another program.  (Addresses Debian bug #204137)
3463
3464Debugfs's mkdir command will automatically expand the directory if
3465necessary.  (Addresses Debian Bug: #217892)
3466 
3467Fixed a bug in debugfs so that copying a file from /dev/null uses the
3468correct mode bits.  (Addresses Debian Bug: #217456)
3469 
3470If the environment variables DEBUFS_PAGER and PAGER are not set,
3471debugfs now searches for the appropriate pager to use, beginning with
3472/usr/bin/pager, and then falling back to 'more' and 'less'.
3473(Addresses Debian bug #221977)
3474
3475Debugfs will now support 2.6 device numbers where the major or minor
3476number may be larger than 255.  (Addresses Sourceforge bug #865289)
3477 
3478Fix debugging printf in resize2fs.  (Addresses Debian Bug #271605)
3479
3480Chattr now stops processing options when it sees '--'.  (Addresses
3481Debian bug #225188)
3482
3483Fix regression tests so they work correctly when e2fsprogs is compiled
3484with configure --disable-htree.
3485
3486Fix bug in uuid library when there is no network card and the library
3487is generating a time-based uuid.  The random MAC address was not
3488correctly generated to be a multicast address.
3489 
3490Add compile_et extensions from Heimdall that were missed the first time
3491around.
3492
3493Fix bug in badblocks when using O_DIRECT; we need to make sure that
3494we're reading from an offset which is page aligned.  For read-only and
3495read-write tests, we try to recover after an error so that we can
3496continue reading on page-aligned boundaries.  (Addresses Debian Bug
3497#203713)
3498  
3499Badblocks now checks 64 blocks at a time instead of 16.  (Addresses
3500Debian bug #232240)
3501 
3502Updated and clarified various man pages.  (Addresses Debian Bug
3503#206845, #222606, #214920, #232406)
3504
3505Updated and fixed translations.   (Addresses Debian bugs #200086, #214633)
3506
3507Fixed various Debian packaging issues (see debian/changelog).
3508
3509Programmer's notes: 
3510-------------------
3511
3512Fixed a build problem so that e2fsprogs would compile with the
3513--enable-profile option to configure selected.  (Addresses Sourceforge
3514bug #811408)
3515 
3516Fixed C++ problems with the ext2fs.h header.  (Addresses Red Hat
3517Bugzilla Bug #112448)
3518                                                                               
3519Centralize code which calculates the location of the superblock
3520and block group descriptors so that it is in a single library routine.
3521
3522Added two new functions, ext2fs_file_open2() and
3523ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3524
3525Fix compile_et to output the correct prototype for
3526initialize_xxx_err_table_r() in the header file.  (Addresses Debian
3527bug #204332)
3528
3529In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3530  
3531Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3532present.  This is for when we try stuffing an int into void * pointer.
3533
3534Fix type-punning which can cause gcc 3.x to miscompile code by getting
3535confused about pointer aliasing.  ext2fs_getmem(), ext2fs_free_mem(),
3536and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3537**'.  The EVMS code uses an ugly union approach since we don't want to
3538modify the EVMS interfaces. 
3539
3540Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3541aid build process on systems can use invoke GNU make as "gmake".
3542
3543Added regression testing for mke2fs.
3544
3545Fixed gcc -Wall nitpicks.
3546
3547Fixed various compiler warnings.
3548
3549Add portability fixes for FreeBSD and for using fsctl under Darwin to
3550support ext2 ioctl's.
3551
3552
3553E2fsprogs 1.34 (July 25, 2003)
3554===============================
3555
3556Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3557a tight loop while waiting for a child fsck to exit in some cases.
3558This burns CPU times which slows down the low-level filesystem check.
3559
3560Added code to mke2fs to assure that the default block size for a
3561filesystem is at least as big as the sector size of the device, if it
3562can be determined.
3563
3564Changed mke2fs and resize2fs to round the default size of a filesystem
3565to be an even multiple of the VM pagesize in order to avoid a Linux
3566kernel bug introduced when the storage of the buffer cache was moved
3567into the page cache.
3568
3569Mke2fs will warn the user when creating a filesystem with journaling
3570and a blocksize greater than 4096.  (Addresses Debian bug #193773)
3571
3572Fixed a bug in resize2fs which caused it to fail on filesystems with a
3573non-empty bad block list.  Resize2fs now discards any blocks on the
3574badblock list which are no longer part of the filesystem as the result
3575of a filesystem shrink.  (Note: this means that shrinking and then
3576enlarging a filesystem is no longer a reversible operation;
3577information about bad blocks in the part of the filesystem which is to
3578be chopped off will be lost.)
3579
3580Changed resize2fs so the user can use prefixes to specify the units of
3581the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3582and to make the error and informational messages explicitly display
3583the blocksize used by the filesystem, in order to avoid confusion.
3584(Addresses Debian bug: #189814)
3585
3586Added a new debugfs command, dump_unused, which dumps the contents of
3587all unused blocks to stdout.  (Useful as an emergency try-to-find
3588deleted data command.)
3589
3590Added a new debugfs command, imap, which prints the location of a
3591specified inode in the inode table.
3592
3593Fixed a bug in the badblocks program which caused it to use one bit of
3594randomness in its non-destructive read/write test, instead of using a
3595full 8 bits of randomness.
3596
3597Added a new option (-t) to badblocks, which allows the user to control
3598the test pattern(s) used when checking a disk.
3599
3600The blkid probe function now more correctly detects UDF filesystems.
3601
3602Fixed a bug in the blkid library which caused it to not update its
3603cache if a filesystem changes from having a label to not having a
3604label.
3605
3606Fixed a bug in the blkid library wihch could avoid an infinite loop
3607in blkid_find_dev_with_tag() if /proc is not mounted and there the
3608/etc/blkid.tab file has not yet been created.
3609
3610Fixed the badblocks program so that the destructive read/write test
3611honors the -c option, and to use O_DIRECT when possible to avoid
3612thrashing the system block buffer cache.
3613
3614Fixed various NLS issues.
3615 - Added Czech and Swedish translations
3616 - Removed testing NYC translation
3617 - Fixed NLS support for message abbrevations in e2fsck
3618 - Remove de-utf.po, since we shouldn't have two versions using different
3619	charset encodings.
3620 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 
3621	simplify the statistics reporting in e2fsck.
3622
3623Changed configure.in so that its defaults for *BSD systems no longer
3624build an fsck wrapper, and not to install in /usr/local by default.
3625
3626Fixed some minor spelling errors/typo's in e2fsck and the configure
3627script.
3628
3629Fixed various Debian packaging issues (see debian/changelog). 
3630
3631Updated and clarified man pages.  (Addresses Debian Bug #195616)
3632
3633Programmer's notes: 
3634-------------------
3635
3636Fix gcc -Wall nitpicks.
3637
3638Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3639NLS support by default.  (Added partial workaround for gettext/Darwin
3640incompatibility problems.)
3641
3642Added full MIT KRB5 and Himdall compaibility support to the com_err
3643library and the compile_et program.  (Addresses Debian bug #191900)
3644
3645Added the blkid_known_fstype() function to the blkid library, which
3646returns true if it is passed a filesystem type which is recognized by
3647the blkid probing functions.
3648
3649Improved the documentation for the blkid library.
3650
3651Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3652returns the hardware sector size of a device, if it is available.
3653
3654Added a dependency in the blkid library's .so file to the uuid
3655library, since the former uses the latter.  (Addresses Debian bug
3656#194094)
3657
3658Added --with-diet-libc and --disable-evms to the configure script.
3659
3660Fixed a minor memory leak in the badblocks program.
3661
3662Fixed a portability problem in tune2fs --- not all systems have strptime().
3663
3664Fixed a portability problem in debugfs with the use of getopt() more
3665than once.  Old-style BSD, new-style BSD, and Linux C libraries all do
3666things differently.
3667
3668Add support Windows support to ext2fs_get_device_size().
3669
3670Added (normally disabled) debugging code to the Unix I/O manager which
3671causes it to disable all userspace caching if the NO_IO_CACHE is
3672defined.
3673
3674Changed the test I/O manager so it can always be linked into e2fsck,
3675mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3676configure script.  The test I/O manager will only print any debugging
3677information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3678variables are set, which specifies which I/O operations are logged and
3679a block number to watch, respectively.  The log messages are sent to
3680stderr by default, unless a filename is specified via the
3681TEST_IO_LOGFILE environment variable.
3682
3683
3684E2fsprogs 1.33 (April 21, 2003)
3685===============================
3686
3687Added a new utility program, logsave, which captures the output of a
3688command in a log file, even if the containing directory hasn't been
3689mounted yet (in which case the it saves the output in memory until it
3690can write out the logfile).  This is useful for capturing the
3691output of fsck during the boot sequence.
3692
3693Fixed some portability problems that were causing problems under
3694the Cygwin32 environment.
3695
3696Mke2fs now interprets a negative number to the -b option as a minimum
3697block size.
3698
3699Fixed a bug in mke2fs which was incorrectly checking the argument to
3700the -g option if the default block size was used.  (Addresses Debian
3701bug #188319)
3702
3703Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3704it can not find filesystem checkers for jfs, reseirfs, and xfs.
3705
3706E2fsck now updates the global free block and inode counters from the
3707block group specific counters quietly.  This is needed for an
3708experimental patch which eliminates locking the entire filesystem when
3709allocating blocks or inodes; if the filesystem is not unmounted
3710cleanly, the global counts may not be accurate.
3711
3712Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree.  (EVMS
37132.0 is not yet supported; this only pulled in the bug fixes: fixed
3714possible hangs caused by bugs in calling waitpid, and not setting the
3715pipe to non-blocking mode; also fixed a file descriptor leak; made
3716sure all functions call log entry/exit functions.)
3717
3718Badblocks now flushes its output file as bad blocks are discovered.
3719
3720The uuid library is now more paranoid about assuming the correctness
3721of the /dev/random device; it mixes in a stream of bytes from
3722random/srandom, just in case.
3723
3724Update Debian files to reflect the fact that I am now the Debian
3725maintainer of e2fsprogs.  Other various Debian-specific packaging
3726cleanups.
3727
3728Move the source tarball generation functions from the top-level
3729makefile to the util/gen-tarball script.  
3730
3731Updated the Turkish .po translation file.
3732
3733Added Heimdal and MIT krb5 extensions to the com_err library to make
3734it more compatible with com_err libraries from those distributions.
3735
3736Changed dumpe2fs to always display the superblock fields relating to
3737the journalling and/or directory indexing feature even if those
3738features are not enabled.
3739
3740Updated and clarify copyright statement vis-a-vis alpha releases of
3741e2fsprogs.
3742
3743The ss library will now try to dynamically link to the readline
3744library and use it if it is present in the system.  This means that
3745the debugfs program now has line editing and history features.  The
3746SS_READLINE_PATH environment variable is used to find a readline or
3747readline-compatible library.
3748
3749E2fsck now finds most duplicate filenames (all when rebuilding all
3750directories via the -D option) and offers to delete or rename
3751duplicate filenames/directory entries.  (Addresses Debian Bug #176814).
3752
3753Fix bug in e2image.  When writing out a raw image file, include data
3754blocks from symlinks that do not store the symlink within the inode.
3755
3756Fix bug in resize2fs which incorrectly moved the block and inode
3757bitmaps for sparse superblock filesystems and incorrectly marked
3758blocks as in use.  (Addresses Debian bug #174766)
3759 
3760Added a new shared library, the blkid library, which efficiently
3761allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3762and UUID filesystem specifiers without needing to search all of the
3763devices in the system.  Instead, the device is looked up in a cache
3764file, and then verified to make sure the blkid cache is correct.
3765
3766Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3767the device name, using the blkid library.  (Addresses Debian bugs
3768#166048, #179671)
3769
3770Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3771used for spaces in device labels.
3772
3773Removed 32-bit limitations for debugfs's dump command.
3774
3775If the user specifies a large number of inodes, Mke2fs will
3776automatically adjust the number of blocks per group to find a valid
3777set of filesystem parameters.
3778
3779Add workaround to detect broken MD devices where when some of the
3780underlying devices are marked read-only, writes to the MD device are
3781silently dropped.  E2fsck will detect if there is an attempt to run
3782the journal twice, and abort with an error if this is the case.
3783(Addresses IBM Bugzilla bug #1226)
3784
3785E2fsck will print an error if more than one of the -p/-a, -n or -y
3786options are specified.
3787
3788E2fsck will fix HTREE corruptions in preen mode, without stopping the
3789boot process.  This is needed because the 2.4 ext2 filesystem
3790accidentally had the INDEX_FL backwards compatibility code removed.
3791
3792Mke2fs no longer creates filesystems with the dir_index flag set by
3793default; the user has to specifically request it.
3794
3795Update and clarified various man pages. (Addresses Debian bugs
3796#173612, #175233, #175113, and #170497, #185945, #188318)
3797
3798Created man page for the mk_cmds program (from the libss library).
3799
3800Programmer's notes: 
3801-------------------
3802
3803Fix various gcc -Wall nits.
3804
3805Fixed a lot of portability problems that caused e2fsprogs not to build
3806successfully under Solaris and Apple/Darwin.
3807
3808Fixed a Makefile dependency to allow building e2fsprogs using parallel
3809make jobs.
3810
3811Changes to create a subset distribution which consists only of the
3812et, ss, uuid, and blkid libraries.  The configure script and top-level
3813makefile were changed to support working with a subset distribution.
3814
3815Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3816actually used, and might people who are looking for
3817EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3818
3819Updated debian files to fix a number of Lintian warnings.
3820
3821Updated config.guess and config.sub with newer versions from the FSF.
3822
3823Removed unnecessary libraries from being linked into the fsck, lsattr, 
3824chattr, and blkid executables.
3825
3826E2fsprogs 1.32 (Nomvember 9, 2002)
3827==================================
3828
3829Fixed a bug in the Unix I/O routines which caused needless writebacks
3830of clean blocks from the unix_io cache (they were erroneously marked
3831as being dirty, so they were getting written back to disk before
3832getting evicted from the disk cache).  This was harmless, but it
3833significantly slowed down e2fsck.
3834
3835Made some other minor optimizations to the Unix I/O routines to save a
3836small amount of CPU time.
3837
3838Updated internationalization files.
3839
3840
3841E2fsprogs 1.31 (Nomvember 8, 2002)
3842==================================
3843
3844Update EVMS ext2fsim plugin with EVMS 1.2.  (We still support
3845compiling the fsim plugin with EVMS 1.0 and 1.1.)  Add better error
3846handling for child process that die unexpectly.  Add a hack to force
3847mkfs to create filesystems that won't cause problems with hardware
3848that has 2k or 4k minimum blocksize requirements.  Read from child
3849processes in non-blocking mode, so that the GUI continues to update.
3850
3851Fix e2fsck so that it returns the appropriate exit code when the root
3852filesystem has been changed, so that system's rc scripts will be told that 
3853the system needs to be rebooted.
3854
3855Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3856was set, some of the descriptor blocks that should have been written
3857out were getting skipped.
3858
3859Changed e2fsck to force out changes to the backup copies of the
3860superblock and block group descriptors when important changes are made
3861to those data structures.
3862
3863Fix a bug where e2fsck could erroneously mark a filesystem as being
3864clean if a check of dirty filesystem is interrupted with a ^C.  (Bug
3865introduced in e2fsprogs 1.28.)
3866
3867If journal debuging is enabled using --enable-jbd-debug, the debugging
3868level is now set via the E2FSCK_JBD_DEBUG environment variable.
3869
3870If byteswapping support is disabled using configure --disable-swapfs,
3871skip the tests which depend on byte-swapping, so that "make check"
3872won't bomb out.
3873
3874Lshattr will now display the indexed directory flag.  Also, some of
3875the more esoteric compression flags are supressed unless compression
3876support has been enabled.
3877
3878Update man pages.
3879
3880
3881E2fsprogs 1.30 (October 31, 2002)
3882=================================
3883
3884When resizing a filesystem, and inodes need to moved, resize2fs will
3885update the inode's ctime field, and the mtime field of the containing
3886directories, so that incremental backups using dump/restore will work
3887correctly.
3888
3889In order to avoid spurious errors, e2fsck wil check the last
3890superblock write time to determine whether or not it can safely use
3891the LOW_DTIME checks to determine if there are inodes on the orphan
3892inode linked list that had somehow gotten disconnected.  (Addresses
3893Sourceforge bug #620980)
3894
3895Partition in /proc/partitions that being with the string "lvm" are
3896considered real partitions even if they do not end with a number.
3897
3898Fixed a bug in the the uuid generation function, where if /dev/urandom
3899is not present, but /dev/random is, and there isn't sufficient
3900entropy, the get_random_byte function could spin a loop forever.
3901
3902E2fsck, mke2fs, etc. will now reliably notice when image files are
3903mounted using the loopback interface.  (Addresses Sourceforge bug
3904#619119)
3905
3906When flushing buffers (as is done by badblocks, for example) check to
3907see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3908FDFLUSH ioctl which causes the MD device driver which causes confusing
3909syslog messages about obselete ioctl messages.  (Addresses Sourceforge
3910bug #545832).
3911
3912Debugfs's write command now checks to see if the destination filename
3913exists before creating it.  (Addresses Sourceforge bug #478195.)
3914
3915When installing man pages, search for compressed man pages using all
3916commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3917
3918Fixed a bug in fsck where multiple filesystems specified on the
3919command were not being checked in parallel due to a logic bug
3920introduced to support the FSCK_MAX_INST environment variable.
3921
3922We have added a new superblock field, s_mkfs_time, which indicates
3923when a filesystem was created.  It is set via mke2fs, and printed out
3924by dumpe2fs, but is not actually touched by the kernel.
3925
3926Dumpe2fs has been made more robust by not aborting if there is an
3927error reading the block/inode bitmaps; instead it will still print out
3928the location of the block/inode bitmaps and inode table.
3929
3930Add support for the an alternative block group descriptor layout which
3931allows for on-line resizing without needing to prepare the filesystem
3932in advance.  (This is the incomat feature flag meta_bg.)
3933
3934Add support for storing default mount options in the superblock, so
3935that the filesystem can be mounted with specific mount options without
3936needing to specify them on the mount command line or in the /etc/fstab
3937file.
3938
3939Add support for a new inode flag, which is to be used for indicating
3940the top of directory hierarchies for the Orlov block allocator.
3941
3942Fix e2fsck so that if it creates the lost+found directory, it does so
3943with the more apporpriate permissions of 0700.  Also change
3944mklost+found so that it also creates the directory 0700.
3945
3946Fixed format bug in e2fsck if NLS is in use.
3947  
3948Add a German translation for e2fsprogs's NLS support.
3949
3950Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3951the beginning of the inode table.  This won't matter much, since if
3952there is a bad block at the beginning of the inode table, the root
3953directory won't be available.  But at least e2fsck won't crash in this
3954case.
3955
3956Fixed endian problems in the htree code for e2fsck and debugfs.
3957  
3958When byte-swapping a filesystem on a PPC architecture, byte-swap the
3959bitmaps since the historical big-endian ext2 variant had byte-swapped
3960bitmaps, and the ext2fs library assumes this.  This fixes the
3961regression test suite on PPC machines.
3962
3963Fix e2image so that it handles a bad block in the inode table
3964appropriately.
3965
3966E2fsck now uses a more sophisticated algorithm to salvage corrupted
3967directories that recovers more information in the corrupted directory
3968block.
3969
3970E2fsck now performs additional consistency checks on indexed (HTREE)
3971directories.
3972
3973Fix bug where efsck might get confused about whether a completely
3974empty directory block is an empty leaf block or an interior htree
3975node.  This could cause e2fsck to get confused into think that a valid
3976indexed directory was corrupted.
3977
3978E2fsck no longer creates an empty directory entry at the end of a
3979directory block when optimizing a directory.  This would cause some
3980earlier versions of the dxdir kernel code to corrupt the directory
3981when attempting to split a node containing an empty directory entry.
3982
3983E2fsck could sometimes in rare circumstances leave the indexed flag
3984set after a small directory was optimized by compressing it instead of
3985indexing it.  (This should never happen in real life, since
3986directories that small wouldn't have been indexed, but better safe
3987than sorry.)
3988
3989E2fsck now only updates the master superblock in all cases.  This
3990slightly shortens its run time.
3991
3992Ext2ed can deal with directory entries of length 0; previously it
3993would get stuck in an infinite loop.
3994
3995Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3996specifiers.  (Sourceforge patch #613447)
3997
3998Badblocks will now work correctly on read-only devices such as
3999CD-ROM's.  (Sourceforge patch #600451)
4000
4001Updated and clarified man pages.  (Addresses Debian bug #167108)
4002
4003
4004E2fsprogs 1.29 (September 24, 2002)
4005===================================
4006
4007Fixed a bug in e2fsck which could corrupt a directory when optimizing
4008it (via the -D option) or rebuiliding the hash tree index with a 1 in
4009512 probability, due to a fence post error.
4010
4011Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4012work correctly.
4013
4014Mke2fs now enables the directory indexing flag by default.  (Since
4015this is a compatible feature flag, it's safe to do so.)
4016
4017Tune2fs will support setting the directory indexing feature flag.  It
4018will automatically set up the default hash algorithm and hash seed
4019fields in the superblock.
4020
4021If the bone-headed user enters the root filesystem twice in
4022/etc/fstab, the -R option which skips the root filesystem will skip
4023all of them.  (Addresses Debian bug #159423).  Note!  This is not a
4024precedent for dealing intelligently with any other kind of doubled
4025entry in /etc/fstab!
4026
4027
4028Programmer's notes: 
4029-------------------
4030
4031Removed perror declaration in lib/et/internal.h.  All modern systems
4032can be expected to define perror() these days.  Besides, the lib/et
4033code wasn't using perror at all anyway.  :-)
4034
4035
4036E2fsprogs 1.28 (August 31, 2002)
4037================================
4038
4039Add support for the Hashed-Tree Directory Indexing to e2fsck.  Support
4040for setting the htree flag is not included yet, although it can be
4041manually turned on via the debugfs program.
4042
4043Clarified e2fsck error message which is printed when it cannot find
4044sufficient contiguous block when relcating filesystem metadata.
4045
4046Added support for building an EVMS plugin module for ext2/3.  This
4047module is substantially the same as the EVMS module shipping with EVMS
40481.1, with one or two bugfixes.  E2fsprogs can also build this plugin
4049for use with EVMS 1.0 (which did not include the ext2 plugin module),
4050if the configure --enable-old-evms flag is given.
4051
4052Fsck will search through EVMS volumes when trying to resolve
4053filesystem specifications such as LABEL=xxx or UUID=xxx.
4054  
4055Added a new utility program, /sbin/findfs, which will return
4056filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4057the device name.
4058
4059Update and clarified various man pages. (addresses Debian Bug #145044,
4060#146437, #131350, #151990, #144621, #141938)
4061
4062If there are no filesystems specified on fsck's command line, fsck now
4063treat that as if the -As options were given.  Previously it would
4064simply do nothing.  (Addresses Debian Bug #153102)
4065
4066Mke2fs no longer treats a failure to be able to clear the MD signature
4067at the end of the filesystem as a fatal error.  (Addresses Debian Bug
4068#155007)
4069
4070The e2p library functions (which are used by lsattr and chattr) now
4071double check to make sure the file is a regular file or directory
4072before attempting to use the ext2 ioctls.  Some device drivers
4073unfortunately respond to the ext2 ioctl's with unknown behaviour.
4074(Addresses Debian Bug #152029).
4075
4076The extended attribute handling has been updated to correspond with
4077the latest V2 bestbits ACL code.
4078
4079Fixed bug in e2fsck which caused it to not clear the dtime field when
4080processing truncated inodes on the orphan list.  This could cause data
4081loss(!) if a filesystem is rebooted before a truncate has been
4082committed.
4083
4084E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4085algorithms.  This makes e2fsck much faster in the case of severely
4086corrupted filesystems where a large number of blocks are claimed by a
4087large number of inodes.  (Thanks to the 2.5 IDE device driver for
4088inspiring this work.)
4089
4090Resize2fs has been significantly sped up when shrinking and expanding
4091a filesystem by a very small number of blocks (for example, when EVMS
4092is converting a partition to be an EVMS legacy volume).
4093
4094Added a new option to e2fsck, -D, which will optimize or compress all
4095of the directories in the filesystem.
4096
4097E2fsck now catches SIGINT and SIGTERM to make sure it will can
4098properly clean up and only exit at safe points.  Fsck will pass
4099SIGINT/SIGTERM to its child processes, and wait until they have all
4100exited before it exits.
4101
4102The uuid parsing code in the uuid library now properly complains when
4103an illegally formated uuid is presented to it.  (Addresses Debian bug
4104#152891)
4105
4106Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4107and 2.4.17, since the workaround can cause problems when using a 2.4
4108kernel with an old version of glibc built with the 2.2 headers.
4109
4110Fixed a bug in mke2fs where it wasn't properly clearing the initial
4111superblock used by other filesystems.  (Addresses Debian bug #147256.)
4112
4113Added support for the synchronous directory feature written by Andrew
4114Morton.
4115
4116The debugfs program can delete directories using the rmdir command.
4117
4118Add support for 8k and 16k filesystems (for systems with page sizes
4119that are greater or equal to 8k or 16k, respectively).  Note that
4120these filesystems can not be mounted on x86 systems, or other systems
4121with only 4k page sizes, due to limitations in the current Linux VM
4122code.
4123
4124Resize2fs requires that the filesystem state be valid and have no
4125errors; otherwise, e2fsck -f must be run first.  (Previously it simply
4126required that the last fsck time be greater than the last mount time.)
4127
4128Configure now defaults the man pages directory to /usr/share/man on
4129Linux systems.
4130
4131E2fsck now offers to truncate inodes which contain too many blocks (so
4132that i_blocks would overflow.  Also fixed handling of large sparse
4133files.
4134
4135E2fsck now more completely checks for symlink validity, including
4136requiring NULL termination and length checks.
4137
4138E2fsck will offer to try forcing a disk write to remap a bad block
4139after finding a read error when reading a filesystem metadata block.
4140
4141Fixed a bug in debugfs which caused the -b and -s options to crash
4142debugfs, as well as breaking the testb, setb, and clearb functions.
4143
4144Added a bmap command to debugfs which calculates the logical to
4145physical block mapping for a particular inode.
4146
4147Fixed a bug in code which checked to see if a device was mounted which
4148sometimes (rarely) failed in the case of a plain file.
4149
4150Fixed a bug in resize2fs where when it reported an error, it would
4151print a message erroneously indicating that the filesystem had been
4152resized before it aborted.
4153
4154When resizing a plain file which is smaller than the requested size,
4155resize2fs will attempt to extended the file so that programs like
4156e2fsck will not complain that the file is too small.
4157
4158Resize2fs will print the actual new size of the filesystem when it is
4159finished resizing.
4160
4161Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4162information on big-endian systems.
4163
4164
4165Programmer's notes:
4166-------------------
4167
4168Fixed collisions with C++ reserved words.
4169
4170Added portability fixes for building e2fsprogs on the HURD and AIX.
4171
4172Added the ext2ed program for creation of test cases.  (ext2ed has many
4173limitations and bugs which make it unsuitable for production use.)
4174
4175The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4176flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4177name_len field is byte swampped on big-endian machines, since in the
4178V2 structure, name_len is a char field which is doesn't need to be
4179byte swapped --- except if an old-style kernel had byte-swapped the
4180name_len field as part of the V1 structure.
4181  
4182
4183E2fsprogs 1.27 (March 8, 2002)
4184==============================
4185
4186The warning messages for mke2fs now go to standard error.
4187
4188Fixed to make sure "make check" runs all of the test programs with
4189LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4190
4191The mke2fs program checks the boot sector for the BSD disk label, and
4192avoids erasing it if it is there.
4193
4194Fixed a bug in e2fsck which caused it to core dump if the journal
4195inode was missing when it was supposed to be there.
4196
4197E2fsck now prints ranges in pass 5 when printing deltas for the block
4198and inode bitmaps.
4199
4200Debugfs's "ls -l" command now will print out the file type information
4201in the directory entry.
4202
4203Create man pages and hard links for fsck.ext3 and mkfs.ext3.  If
4204mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4205
4206Debugfs can now examine the experimental directory indexing
4207information.
4208
4209Fixed bug in debugfs which caused it to core dump if modify_inode is
4210called without an open filesystem.
4211
4212The debugfs lsdel command now runs its output through a pager first.
4213
4214When installing manual pages, remove the compressed manual pages first.
4215
4216Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4217
4218Fix the 2.4 resource limitation workaround introduced in 1.26 which
4219actually broke things on mips32, sparc32, and Alpha platforms.
4220
4221Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4222(which is required by the newer libintl libraries).
4223
4224Programmer's notes:
4225-------------------
4226
4227Fixed various gcc -Wall complaints.
4228
4229Fixed a few memory leaks in the e2fsck journaling code, and in the
4230ismounted code checking for a swap device.
4231
4232Add new inode I/O abstraction interface which exports an inode as
4233an I/O object.
4234  
4235Exported ext2_file_flush as a public interface.
4236  
4237In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4238
4239Lots of small random portability fixes to make e2fsprogs build under
4240AIX --- even without the 5L compatibility toolkit, and even using the
4241uber-crippled AIX native C compiler.
4242
4243
4244E2fsprogs 1.26 (February 3, 2002)
4245=================================
4246
4247Dumpe2fs will keep going now if the bad block inode can't be read.
4248(Previously it stopped with a fatal error.)
4249
4250E2fsck will now give an opportunity to run the journal even if the
4251recovery flag is not set.  This is the default behaviour if e2fsck is
4252using a backup superblock, since the needs_recovery flag will never be
4253set in the backup superblock copies.
4254
4255E2fsck now automatically finds the backup superblock/group descriptors
4256even when the primary superblock is completely destroyed for 2k and 4k
4257filesystems.  (Previously it just guessed/assumed that we were dealing
4258with a 1k filesystem in that case, and users had to manually specify
4259the backup superblock number.)
4260
4261Fixed a bug in e2fsck where it dereferences a null pointer when there
4262is a problem opening a filesystem in preen mode.
4263
4264E2fsck now handles external journals correctly; previously it trashed
4265the external journal device if the journal needed to be replayed.
4266
4267Work around ulimit incompatibility problem caused by recent 2.4
4268kernels; the unix IO module will automatically try to set any resource
4269limits to be infinite on startup.
4270
4271Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4272bitmap if it wasn't present and the blocksize was 2k or 4k.
4273 (Addresses Debian Bug #116975)
4274
4275E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4276clearing the new V2 fields if they do not make sense or if the ext3
4277superblock is version 1 superblock.
4278
4279E2fsck will automatically relocate the ext3 journal from a visible
4280file (i.e., /.journal) to an hidden inode if the filesystem has been
4281opened read/write.  This allows the users to add a journal while the
4282filesystem is mounted, but the next time the system is rebooted, the
4283journal file will disappear.  This avoids problems with backups,
4284stupid operators with superuser bits, etc.
4285
4286Fix a bug in fsck where it would not support a filesystem type of
4287"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4288
4289Fsck now supports fstab entries of the form "ext3,ext2".  It will also
4290automatically identify reiserfs filesystems.
4291
4292The number of processes spawned by fsck can now be limited using the
4293FSCK_MAX_INST environment variable.
4294
4295Fsck now searchs the LVM proc hierarchy to find logical volumes which
4296should be searched for  UUID and label information.
4297
4298Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4299limit if at all possible, when opening a block device.  (The filesize
4300limit shouldn't be applied against writes to a block device.)
4301
4302In mke2fs and e2fsck, specifying the -c option twice will now do
4303a read/write test on the disk.  Update the man pages to encourage
4304using the -c option, and to discouraging running badblocks separately,
4305since users tend to forget to set the blocksize when running 
4306badblocks.
4307
4308Mke2fs now automatically clears the immutable attribute on a
4309pre-existing .journal file left over from a previous failed attempt to
4310add a journal to an alreadyy-mounted filesystem.
4311
4312Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4313operation failed.
4314
4315Mke2fs now creates the lost+found directory with permissions of 0700,
4316so that files that had previously lived in protected directory are
4317safe if they get dropped in lost+found and the system administrator
4318doesn't deal with immediately.  (Addresses Debian #bug 118443)
4319
4320Mke2fs and e2fsck (and all programs that use the
4321ext2fs_check_if_mounted function) will now properly identify that a
4322device is mounted, even in cases where devfs has confused things with
4323multiple devices names with the same identity, or if a dim-witted
4324system administrator has done something stupid like creating device
4325file aliases in their home directory.  Also now checks for swap devices
4326by using /proc/swaps.  (Addresses Debian bug #106622)
4327
4328Added a new option (-T) to tune2fs which sets the time a filesystem
4329was last checked.
4330
4331Speed up e2image when creating sparse raw image files by optimizing
4332away excess lseek() system calls.
4333
4334Fix support of large (> 2GB) files when used as a filesystem in
4335mke2fs, tune2fs, debugfs, and findsuper.
4336
4337Debugfs's stat and icheck commands now properly deals with large (>
43382GB) files.
4339
4340Debugfs's set_super_value command now prints out the list of valid
4341superblock fields which can be set using the command.
4342
4343Debugfs's rm and kill_file command now updates the superblock free block
4344and inode counts, thus keeping the filesystem consistent.
4345
4346Debugfs's lsdel command now takes an optional argument which allows
4347the user to only see the most recently deleted files.
4348
4349A new command (undel) was added to debugfs which automates
4350undeleting a deleted inode and linking it back to a directory.
4351
4352Debugfs's ls command now takes a new option, -d, which lists 
4353deleted directory entries.
4354
4355Debugfs's testb, freeb, setb, and find_free_block commands now take an
4356optional count argument.
4357
4358Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4359be used to signal that a particular inode should not be eligible for
4360tail-merging --- this is needed for programs like LILO.
4361
4362The findsuper (an unreleased, uninstalled utility program) has been
4363improved to add extra validity checks and to add a progress meter.
4364(It is still an unsupported program; the officially supported way to
4365recover from a trashed partition table is to use gpart; findsuper is
4366for wizards only.  :-)
4367
4368Debugfs was fixed to compile with "configure --disable-swapfs".
4369
4370Cleaned up various manual pages.   (Addresses Debian bug #119624, #120171)
4371
4372Added new translation file for Turkish.
4373
4374Programmer's notes:
4375-------------------
4376
4377Fix general gcc -Wall complaints.
4378
4379E2fsprogs (mostly) works with the dietlibc.
4380
4381The programming texinfo file has been expanded to include description
4382of additional libext2fs functions.  (Still not compeltely done, but a
4383lot of the more important functions have been documented.)
4384
4385Added a umask structure to struct_ext2_filsys, which currently only
4386modifies the behaviour of ext2fs_mkdir(), but if we add any file
4387creation functions to libext2fs, we should also make sure they respect
4388the umask setting.
4389
4390The build-rpm script was fixed to be a bit more safe.
4391
4392The tests' Makefile now has a way of automating test case creation 
4393for e2fsck, using "make testnew".
4394
4395Created a new function, ext2fs_dir_iterate2 which passes more
4396information to the callback function (identical to the one used by
4397ext2fs_dblist_dir_iterate).  The directory iterator functions take a
4398new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4399directory entries.  If the directory entry is deleted, the callback
4400function will be called with the entry paraemter set to
4401DIRENT_DELETED_FILE.
4402  
4403Added new functions, ext2fs_inode_alloc_stats and
4404ext2fs_block_alloc_stats, which takes updates block/inode allocation
4405statistics in the bitmaps, block group descriptors, and superblock
4406when inodes or blocks are allocated or deallocated.
4407
4408
4409E2fsprogs 1.25 (September 20, 2001)
4410===================================
4411
4412This is primarily a bug-fix release; no new features were added, but
4413there are a number of embarassing bug fixes and cleanups applied.
4414
4415Fix a bug mke2fs which causes stack garbage to be written to disk when
4416zapping disk sectors.  (This bug could cause mke2fs to core dump for
4417some kernels, I suspect with security enhancement patches.)
4418
4419Remove unneeded #include of <linux/config.h> which was breaking
4420building e2fsprogs on the Hurd.  (Addresses Debian bug #112414.)
4421
4422Updated tune2fs man page to reflect the fact that adding or removing a
4423journal doesn't require running e2fsck.
4424
4425Remove use of AC_REQUIRE from autoconf which had been used to prevent
4426AC_CANONICAL_HOST from being called twice; unfortunately this causes
4427recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4428used outside of autoconf macros.  Fortunately, it doesn't seem to be
4429necessary any more, anyway.
4430
4431E2fsck will now not fall back to an alternate superblock if the user
4432specifies the superblock location explicitly on the command-line.
4433This allows easier recovery from a situation where the primary
4434superblock and block groups are slightly corrupted, but the backup
4435superblocks are completely broken.  
4436
4437Fix problem which caused compile_et and mk_cmds to blow up if
4438e2fsprogs was in a directory with a pathname that contained spaces.
4439
4440We are now more paranoid about checking the entry in /etc/mtab to make
4441sure the filesystem is really mounted, since some broken distributions
4442(read: Slackware) don't initialize /etc/mtab before checking non-root
4443filesystems.  (Slackware also doesn't check the root filesystem
4444separately, and reboot if the root filesystem had changes applied to
4445it, which is dangerous and broken, but there's nothing I can do about
4446that.)
4447
4448Make UUID library C++ friendly by adding appropriate extern "C"
4449declarations and using const in the function declarations.
4450
4451Fix up the com_err texinfo file so that it can product a valid info
4452file (previously, it could only be used to generate paper
4453documentation using texinfo.tex).
4454
4455
4456E2fsprogs 1.24a (September 2, 2001)
4457===================================
4458
4459Fix brown-paper bug in mke2fs which caused it to segfault when
4460printing the version string.
4461
4462
4463E2fsprogs 1.24 (August 30, 2001)
4464================================
4465
4466Revert the BLKGETSIZE64 support, since for some distributions, this
4467ioctl has been used by an unofficial kernel patch to update the last
4468sector on the disk, and this was causing disk corruption problems as a
4469result.
4470
4471Mke2fs is now more careful about zapping swap space signatures and
4472other filesystem/raid superblock magic values so that programs like
4473mount who try to use hueristics to determine the filesystem type of a
4474partition are less likely to be confused.
4475
4476E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4477regular file (since Andreas Dilger's on-line resizing tools will set
4478its mode bits).
4479
4480Fixed some minor texinfo, man pages nits for spelling errors,
4481texinfo warnings, etc.  (Addresses Debian bug #110621.)
4482
4483E2fsprogs program no longer print the filesystem version number
4484(i.e. 0.5b), since it only confuses people and doesn't serve any real
4485purpose.
4486
4487E2fsck will once again compile under libc5, since it will supply its
4488own version of strnlen if necesssary.
4489
4490mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4491when specifying the external journal device.  tune2fs will also search
4492devices looking for the externla journal debice when removing.  
4493
4494E2fsprogs 1.23 (August 15, 2001)
4495================================
4496
4497Add initial support for extended attributes (EA); e2fsck will
4498correctly handle a filesystem with EA's and check the EA blocks for
4499corruptions.
4500
4501E2fsck's symlink sanity checking has been cleaned up.  It now checks
4502the i_size value of fast symlinks, and checks for immutable flags
4503being set of symlinks, etc.
4504
4505E2fsck now offers to clear inodes which are special files that have a
4506non-zero i_blocks or i_size field.  (The i_size field check was in the
4507previous version of the code, but due to a bug it didn't offer to
4508clear the inode unless i_size and i_size_high were both non-zero.)
4509
4510E2image can now create "raw" image files, which only contain the
4511filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4512debugfs, etc., can be run directly on the raw image file.
4513
4514Add support for the 64-bit block device patches.
4515
4516Fixed bugs in creating external journals with a 1k blocksize.
4517
4518Add initial support for external journals (so long as the external
4519journal only supports a single filesystem) in e2fsck.
4520
4521Remove requirement for needing to run fsck on a filesystem after
4522removing a journal (either internal or external).
4523
4524The man pages now document how to create and manage external journals.
4525
4526Speed up the check of an ext3 filesystems by avoiding a needless flush
4527of all of the superblock and block group descriptors.
4528
4529Speed up creating an internal journal using tune2fs in the case where
4530the filesystem has a lot blocks already allocated.
4531
4532Tune2fs has been fixed to make sure that only error messages go to
4533stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4534
4535Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4536now not set the sparse_super feature.  (Addresses Debian bug #108165)
4537
4538Add support in fsck for the filesystem type "auto".
4539
4540Fsck -A will not try to interpret device names for filesystems which
4541have a pass number is 0.  (Addresses Debian bug #106696).
4542
4543Fsck prints a warning message if now valid filesystems are passed to
4544it.  (Addresses Debian Bug #107458.)
4545
4546E2fsck now gives an explicit warning if there filesystem still has
4547errors at the end of the run. (Addresses Debian bug #104502)
4548
4549E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4550reflects an error.  E2fsck will also not run the orphan list if the
4551filesystem contains errors, since the orphan list might be corrupted.
4552
4553E2fsck now prints the number of large files when given the -v option.
4554
4555Fixed minor memory leaks in e2fsck.
4556
4557Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4558
4559
4560E2fsprogs 1.22 (June 22, 2001)
4561==============================
4562
4563Fixed a bug in e2fsck's handling of orphan inodes which are special
4564files (i.e., block/character device files, named FIFO's, etc.).
4565
4566Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4567tune2fs to fail at adding a journal to a mounted filesystem.
4568
4569Fixed a few big-endian bugs in e2fsprogs
4570	* The directory block functions were accidentally reporting
4571		some directories as corrupted when they weren't.
4572	* If e2fsprogs is compiled --disable-swapfs, the C language 
4573		equivalents weren't being included for big-endian platforms.
4574		(Fixes Debian bug #101686).
4575
4576Fixed a Hurd compilation problem.  (Addresses Debian bug #101361)
4577
4578Programmer's notes:
4579-------------------
4580
4581Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4582ioctls, and allow them to be defined for non-i386 platforms.
4583
4584The uuid.h header file is now protected against multiple inclusions.
4585
4586E2fsprogs is now being developed using BitKeeper.  Changed the test
4587scripts to deal with BK's stripping CR characgters from text files,
4588and changed the top-level Makefile.in to avoid including BitKeeper
4589files when generating the source tarball.
4590
4591
4592E2fsprogs 1.21 (June 15, 2001)
4593==============================
4594
4595Added new configure flags which allow a subset e2fsprogs to be built;
4596this is most useful for boot floopies, since the resulting shared
4597libraries and programs are slimmed down by removing features that
4598aren't necessary for a boot floppy.  The new flags that were added
4599are: --disable-swapfs, which removes support for byte swapping old
4600legacy PPC/68k filesystems, --disable-debugfs, which removes support
4601for debugfs from the libext2fs library, --disable-imager, which
4602removes support for the e2image program, and --disable-resizer, which
4603removes support for resize2fs.
4604
4605E2fsck now prints the number of mounts or days elapsed since the last
4606check when e2fsck is forced to check an otherwise clean filesystem.
4607
4608Tune2fs now prints an informative message about how often a filesystem
4609will be checked when adding a journal to the filesystem, to remind the
4610user that he/she may want to adjust those parameters using tune2fs
4611-c/-i.
4612
4613Worked around hurd brain-damage which causes e2fsck to sometimes
4614believe a filesystem is the root filesystem based on device numbers
4615(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4616violation).
4617
4618Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4619erroneous error with the -F option was specified.
4620
4621Fixed a ext3 recovery bug in the revoke handling; synchronized with
4622ext3 0.7a.
4623
4624Fixed two bugs in e2fsck's handling of dup block handling, dealing
4625with relatively uncommon edge cases: a directory with an indirect
4626block which is claimed by another file, and when the last inode in the
4627filesystem has blocks claimed by another file.
4628
4629E2fsck now checks to see if the i_size field of a fast symlink is too
4630big, and offers to clear the symlink if so.
4631
4632E2fsck now checks to see if i_size_high of special files is non-zero,
4633and offers to clear i_size_high.
4634
4635Fix e2fsck's handling of incompatible journal flags so that the user
4636has chance to abort, and then has the option to clear out the journal
4637entirely.  (Addresses Debian bug #98527.)
4638
4639Fixed a bug in fsck which could cause it to core dump if a mix of
4640standard and non-standard device names are used in /etc/fstab.
4641(Debian bug #100559)
4642
4643Fixed a bug in debugfs which caused read errors when copying a file to
4644not be noticed.
4645
4646The debugfs set_super_value command can now modify the s_lastcheck field.
4647
4648Fixed a bug in lsattr and chattr which was accidentally introduced in
46491.20 to support > 2GB files; both lsattr and chattr wasn't reading
4650directories correctly because the change modified the layout of struct
4651dirent to be incompatible with the libe2p shared library.
4652
4653Cleaned up the mke2fs manual page and included a discussion about why
4654it's good to periodically check the filesystem even when journaling is
4655enabled.
4656
4657Programmer's notes:
4658-------------------
4659
4660Fix general gcc -Wall complaints.
4661
4662The types needed by the ext2 header files are now provided by
4663lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4664
4665Integers are now preferred to longs when trying to find a 32-bit type
4666in ext2_types.h.  Also, if linux/types.h has already been defined,
4667don't try to redefine the types.
4668
4669Fixed make depend script so that it automatically corrects the
4670pathname cleanups performed by make -M, so I don't have to fix them up
4671by hand.
4672
4673Fixed the d_loaddump test case to be more robust, and not depend on
4674bash'isms.
4675
4676Removed debugfs's dependence on pread(), which was accidentally
4677intrudced in e2fsprogs 1.20
4678
4679Fixed a performance bug in the libext2fs's icount routine; the size
4680estimate of the icount array was incorrectly being calculated.
4681
4682Removed use of the badblocks compatibility functions in the e2fsprogs
4683programs.
4684
4685Added paranoia code which protects against strange cases where /etc
4686isn't on the root filesystem, or if /etc/mtab doesn't exist.
4687
4688The header file ext2_types.h is now installed.
4689
4690Autoconf is used to determine when we are on big-endian machines,
4691instead of doing run-time tests, to save a few bytes of code.
4692
4693The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4694functions are no longer inline functions, which saves space and
4695doesn't really cost any real performance.
4696
4697The ext2fs library no longer depends on the e2p library.  (What need
4698there was of it --- namely, fsetflags, was coded in-line).
4699
4700Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4701when the user is stupid and tries compiling the package using "make
4702install" as root.
4703
4704Miscellaneous code cleanups:
4705	* Added missing files from Makefile.in's SRCS file, so that 
4706		their dependencies would be properly calculated.
4707	* Removed redundant code
4708	* Fixed comments in code
4709	* Removed no-longer unneeded argsused #pragma.
4710
4711
4712E2fsprogs 1.20 (May 20, 2001)
4713=============================
4714
4715Add support for replaying the ext3 journal purely in user mode,
4716including handling the orphaned inode list.  Used code contributed by
4717Andreas Dilger, with bug fixes and the orphaned inode handling done
4718by Theodore Ts'o.
4719
4720The mke2fs and tune2fs programs can create or modify a filesystem to
4721include an ext3 journal.  Tune2fs also can be used to remove an ext3
4722journal from a filesystem.
4723
4724E2fsck will now check for the existence of a linked list of orphan
4725inodes in the superblock, and clear those inodes before starting the
4726rest of the filesystem check (but after the journal playback).
4727
4728E2fsck now validates the file descriptor passed to the -C option,
4729which saves against the completion bar getting written to an
4730unexpected location, such as the disk being checked.  (Debian
4731bug/wishlist #55220)
4732
4733E2fsck will now bump the filesystem revision number from zero to one
4734if any of the compatibility bits are set.
4735
4736Fixed a bug where a badly corrupted directory on a big endian system
4737could cause e2fsck to die with a bus error.  The
4738ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4739the ext2 library now does alignment sanity checks on the rec_len field
4740of the directory entry before using it.
4741
4742The ext2 library has been enhanced to make tune2fs safe to run on
4743mounted filesystems.  (Users could usually get away with using tune2fs
4744on mounted filesystems before, but with the advent of ext3 and
4745journaling, it became important to make tune2fs was *really* safe for
4746use even when the filesystem being modified is mounted.)  E2label is
4747now implemented by tune2fs using an argv[0] dispatch, so that e2label
4748is also now safe for use on mounted filesystems.
4749
4750Added a new program, e2image, which creates a backup of critical ext2
4751filesystem data structures.  The generated image file can be examined
4752using dumpe2fs and debugfs.  In the future, e2fsck will be able to use
4753the image file to help recover very badly damaged filesystems.
4754
4755Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4756no longer cause e2fsck to bomb out.  Also treat files > 2GB as being
4757large file when deciding whether or not the filesystem has large files.
4758
4759Fixed lsattr and chattr so that they work correctly on large files.
4760(Fixes Debian bug #72690.)
4761
4762Removed limitation in get_device_size() which imposed a one terrabyte
4763filesystem limitation.  (Most 2.2 kernels still have a signed int
4764problem which cause 1 TB block device limitation.  Fortunately, the
4765kernel patches to fix this are much easier than fixing the 2TB
4766limitation in the kernel.  :-)
4767
4768A max_mount_count of zero is now treated as if no mount count were
4769set.  (Previously, no mount count was indicated by using -1, and a
4770mount count of zero caused e2fsck to always be run.)
4771
4772Mke2fs supports two new filesystem types largefile and largefile4.
4773
4774Mke2fs now adds some randomness in s_max_mount_count so that multiple
4775filesystems won't be all checked at the same time under normal
4776operations.
4777
4778Fixed bug in the progress bar printing code which could cause e2fsck
4779to core dump on an illegal filesystem.
4780
4781Fixed bug in fsck which could allow more than one instance of e2fsck
4782to be printing a progress bar.  (Debian bug #65267)
4783
4784Fsck using a UUID or a LABEL specifier will work even if devfs is
4785compiled into the kernel and not mounted.  If the pathnames in
4786/proc/partitions are incorrect, fsck will search /dev for the correct
4787device (using the new ext2fs_find_block_device library function).
4788Fsck now also checks the RAID devices first so that they are properly
4789found when they are in use.  Support has also been added to support
4790additional IDE disks and the DAC 960 device names.  (Debian bug #94159)
4791
4792Fixed a bug in fsck which caused it not deal properly with 16
4793byte long filesystem labels.
4794
4795Fsck's -t option has been made a lot more flexible.  The semantics for
4796what happens if a comma-separated list to fsck has been regularized,
4797and it is now possible to filter what filesystems will get checked
4798based what is in the filesystem's fstab entry's option field.  (Debian
4799bug #89483.)
4800
4801The dumpe2fs program can now print out the group description
4802information in hex, and also prints the location of the superblock and
4803block group descriptor for those block groups that have them.
4804
4805Mke2fs now clears the ext2 superblock before it starts creating a
4806filesystem, so that the superblock magic number is only written if the
4807filesystem creation process successfully completes.
4808
4809The debugfs program's stat command now pretty-prints the blocks used
4810by an inode so that it's more compact and informative.
4811
4812The debugfs stats command now uses the same libe2p code (which is used
4813by dumpe2fs) to print the superblock header information.  This is more
4814complete, and it avoids a bit of code duplication.
4815
4816Added a new debugfs command, set_super_value (ssv) which allows the
4817user to set arbitrary superblock fields.
4818
4819Debugfs was extended to support inode numbers in hex (by prefixing
4820them with 0x), and so that modify_inode can set the inode generation
4821number.  Also, there is now a new function command called logdump
4822which will dump an ext3 journal.
4823
4824Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4825debugfs.
4826
4827Debugfs's dump command now stops immediately upon reporting a disk
4828read error.  (Fixed a bug in ext2fs_file_read library routine which
4829caused debugfs not to stop.)  (Debian bug #79163)
4830
4831On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4832checked before /etc/mtab is used, since /proc/mounts is more likely to
4833be accurate.
4834
4835Added portability fixes for Solaris and Linux/ia64.
4836
4837Various manual pages were clarified and cleaned up.  (Fixed debian
4838bugs #63442, #67446, and #87216)
4839
4840
4841Programmer's notes:
4842-------------------
4843
4844The e2fsck message printer now supports %Iu and %Ig, which will print
4845out the inode's user and group owners, respectively.
4846
4847E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4848that no longer dependent on the system having the correct version of
4849the kernel header files.
4850
4851Added a new function to libext2, ext2fs_find_block_device(), which
4852searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4853device given its device number.
4854
4855Added a new function to libext2, ext2fs_sync_device, which centralizes
4856all of the places which might try to use the BLKFLSBUF or FDFLUSH
4857ioctls (and usually failing to define them since the system header
4858files don't usually do this for us, and we're trying to avoid usage of
4859kernel include files now).
4860
4861Added new utility programs in tests/progs: random_exercise and
4862hold_inode.  They aren't built by default; they're useful for
4863exercising ext3 filesystem code.
4864
4865Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4866the filesystem close functions to only update the superblock, and to
4867not touch the block group descriptors.  Needed by tune2fs when
4868modifying a mounted filesystem.
4869
4870Got rid of struct ext2fs_sb and replaced it with the standard struct
4871ext2_super_block from include/linux/ext2_fs.h.  Note: this may break
4872source (but not binary) compatibility of some users of the ext2
4873library.  Those applications should just simply do a global search and
4874replace of struct ext2fs_sb with struct ext2_super_block, and include
4875the new header file <ext2fs/ext2_fs.h> which defines it.
4876
4877The ino_t type has been renamed ext2_ino_t to protect applications
4878that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4879inexplicably changes ino_t(!?).  So we use ext2_ino_t to avoid an
4880unexpected ABI change.
4881
4882The Makefiles have been reworked so that "make check" can be run from
4883the top-level Makefile.
4884
4885Fix general gcc -Wall complaints and removed dead code.
4886
4887Remove use of NOARGS, because we assume everyone does ANSI C these
4888days.
4889
4890Added build-rpm script from sct.
4891
4892New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 
4893to support e2image.
4894
4895New function ext2fs_flush_icache which must be called if the
4896application program modifies the inode table blocks without going
4897through ext2fs_write_inode() interface.
4898
4899New ext2fs_check_mount_point() function, which will return the mount
4900point of a device if mounted.
4901
4902The io_channel abstraction now has an optional interface,
4903io_channel_write_range, which allows specific byte ranges to be
4904written.  
4905
4906The unix_io IO channel now supports write-through caching, so that
4907journal creation is more efficient.
4908
4909Added x86 assembly language routines to support byte swapping, to
4910reduce executable size.
4911
4912Fixed bug in the utility program subst so that it's possible to
4913replace a substitution variable with a zero-length string.
4914
4915Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4916slipped into some of the problem number.
4917
4918E2fsprogs 1.19 (July 13, 2000)
4919==============================
4920
4921Release the resize2fs program since the timeout before it could
4922be released under the GPL has finally expired.
4923
4924Add experimental support needed for the ext2 compression patches.
4925This requires compiling e2fsprogs with the --enable-compression flag
4926to the configure script.
4927
4928Added ext3 journalling support.  E2fsck will run the journal (if
4929necessary) by temporarily mounting the filesystem.  /sbin/fsck.ext3 is
4930installed as a symlink to e2fsck.  Fsck has been taught about ext3,
4931and treats it the same as ext2 in terms of the progress bar logic.
4932Dumpe2fs will display the superblock journaling information if the
4933filesystem has a journal.  The ext2 library will now permit opening an
4934ext3 filesystem with the recovery flag set.  This is necessary for
4935on-line dump's to work correctly, but there may be issues with this
4936working well since ext3 is much less agressive about syncing blocks to
4937the filesystem, since they're safe on the journal.
4938
4939Tune2fs and e2fsck have been changed to allow the mount_count check to
4940be disabled by setting max_mount_count to -1.  (This was already
4941supported by the kernel.)
4942
4943Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4944are used for ext3 as well.
4945
4946Added internationalization support for e2fsprogs; must be enabled
4947by passing --enable-nls to configure.
4948
4949Always use the provided ext2fs header files to insulate ourselves from
4950kernel version changes.  Which include files are used by e2fsprogs
4951have also been cleaned up to improve portability.
4952
4953Limit the number of times that e2fsck updates the progress bar so that
4954people who are booting using a 9600 baud console don't get swampped by
4955too many updates.
4956
4957Improved the loop detection algorithm in e2sck's pass #3 so that it is
4958much, much faster for large filesystems with a large number of
4959directories.
4960
4961The memory footprint for e2fsck is now slightly smaller than before.
4962
4963E2fsck now checks if special devices have a non-zero size, and offers
4964to clear the size field if it finds such an inode.  
4965
4966E2fsck now checks if special devices have the append-only flag set,
4967and offers to clear the inode.
4968
4969E2fsck now properly handles some "should never fail" cases during a
4970bitmap copy in pass5.
4971
4972E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4973
4974E2fsck now calculates the correct location of the backup superblock in
4975the case of filesystem blocksizes > 1k.
4976
4977Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4978which normally didn't cause problems under most filesystem parameters,
4979but could cause a valid superblock to be rejected in extreme cases.
4980Other checks for validating superblock values were made more
4981stringent.
4982
4983Added non-destructive write testing to the badblocks program, courtesy
4984of David Beattie.  The badblocks also now has an option to input the
4985current set of bad blocks, so that known bad blocks are skipped to
4986speed up the badblocks test.  There is also a persistent rescan
4987feature which causes badblocks to run until it has completed some
4988number of passes without discovering any new bad blocks.
4989
4990Badblocks now checks to see if the device is mounted and refuses to do
4991the tests involving writing to the device if it is mounted.  Also,
4992badblocks now allows the number of blocks to be checked to be
4993defaulted to the size of the partition.
4994
4995Fixed a bug in fsck which didn't allow non-root users to be able to
4996check filesystems if there were any LABEL= or UUID= entries in
4997/etc/fstab.
4998
4999The Hurd doesn't support the filetype filesystem feature.  The mke2fs
5000program now makes sure that for the Hurd, the filestype feature is
5001turned off.  E2fsck will check to see if the filetype feature is
5002turned on for Hurd filesystems, and offer to turn off the feature.
5003
5004Mke2fs now has a safety check to make sure the number of blocks do not
5005exceed 32 bits even on a 64 bit platform.
5006
5007Really fixed a bug in fsck to allow "fsck -As" to run interactive
5008fsck's.  (For those people who like to do interactive fsck's in the
5009/etc/rc scripts!?!)
5010
5011Debugfs has a few new features: the rdump command, which will do a
5012recursive dump of a directory and all of its contents, and the lcd
5013command which does a local chdir (much like the ftp command of the
5014same name).  In addition, the debugfs program and the open_filesystem
5015command now takes three new options: -b and -s, which allows the
5016blocksize and superblock location to be specified, and the -c option
5017which is used in catastrophic situations where the block group
5018descriptors are corrupt.  If the -c option is specified, debugfs will
5019skip trying to read in the block and inode bitmaps.
5020
5021Debufs's lsdel command was fixed to handle bad blocks in the inode
5022table.
5023
5024A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
50254 digit years.
5026
5027General improvements in error messages
5028
5029  - Mke2fs prints a sane error message if the partition size is zero
5030	(usually because the partition table wasn't reread by the
5031	kernel due to the partition being busy), instead of "invalid
5032	argument passed to ext2 library while initializing superblock".
5033
5034  - Fsck now prints more self-explanatory message if an invalid UUID=
5035	or LABEL= specification is passed to it.
5036
5037UUID library changed to use the LGPL.
5038
5039Fixed a bug in the UUID library where very rapid calls to the
5040time-based UUID generator could cause duplicate UUID's to be returned.
5041This was not a problem for e2fsprogs, but it could be a problem for
5042other users of the library.
5043
5044Make the UUID library more robust in the face of missing or an
5045improper /dev/urandom or /dev/random files.
5046
5047Added some random portability fixes for Solaris.
5048
5049Some minor man page updates.
5050
5051Fixed a memory leak in the ss library.
5052
5053
5054Programmer's notes:
5055-------------------
5056
5057We now try to use lseek64 and open64 from the LFS if possible.
5058
5059The 3rd parameter in e2p's print_flags is now a flags word, instead of
5060a boolean option.
5061
5062The mark and unmark bitmap functions now return the previous state of
5063the bit that was being changed, which is useful for some speed
5064optimizations.
5065
5066The following functions have been added to enhance the badblocks list
5067handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5068ext2fs_badblocks_equal.
5069
5070The ext2 header files now have the latest journalling fields to the
5071superblock.
5072
5073The ext2fs_mkdir function in libext2fs now properly backs out of error
5074conditions robustly.
5075
5076Cleaned up makefiles:
5077  - to cleanly  compile with the -j flag.
5078  - so distclean removes all generated files.
5079  - so in case of an error while installing header files, the make aborts.
5080
5081Fix test_script so that it works correctly when compiling in the
5082source directory.
5083
5084The random UUID generation routine has been made slightly better in
5085the case where /dev/random doesn't exist.  (Use of randomly-based UUID
5086is still not recommended if /dev/random doesn't exist, however; it's
5087better to use the time/ethernet MAC address UUID in this case.)
5088
5089Clean up the build process so it's more friendly in case of missing
5090directories.
5091
5092The ext2fs header file can now be #include'd into C++ programs.
5093
5094The e2p.h header file is now installed.
5095
5096Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5097
5098
5099
5100E2fsprogs 1.18 (November 10, 1999)
5101==================================
5102
5103Fix a core dumping bug in e2fsck if an imagic inode is present or
5104(more rarely) if the filesystem is badly corrupted enough that e2fsck
5105has to restart pass 1 processing.  E2fsck now closes the filesystem
5106before freeing a large number of its data structures, so in the case
5107of future memory faults, at least the fixed filesystem will be fully
5108written out.
5109
5110If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5111imagic inode, it will offer to clear the imagic flag.
5112
5113E2fsck will now offer to clear the immutable flag on special files
5114(device/socket/fifos) when running it in non-preen mode.
5115
5116E2fsck will now set the filetype when creating /lost+found, and when
5117connected orphaned inodes to /lost+found.
5118
5119Debugfs's ncheck and icheck commands now handles the case where there
5120are bad blocks in the inode table without bombing out.
5121
5122The badblocks list processing code has been made more efficiently for
5123appending a large number of (ordered) badblocks to the badblocks list.
5124
5125Some minor man page updates.
5126
5127Fsck now allows interactive e2fsck's when using fsck -As (not a common
5128mode, but some people like to do this in boot scripts for silly reasons).
5129
5130Programmer's notes:
5131-------------------
5132
5133The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5134with the problem code convention.
5135
5136The badblocks list regression test program has been updated to work
5137with previously made API name changes.
5138
5139The ext2fs_free() command now uses the new badblocks API to avoid
5140using the compatibility layer.
5141
5142Added new regression test cases; the run_e2fsck test script now
5143supports the ability for a test case to run a prepratory command
5144before running e2fsck.
5145
5146E2fsprogs 1.17 (October 26, 1999)
5147=================================
5148
5149Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5150infinite loop.
5151
5152Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5153thus potentially causing problems if a binary UUID contained a NULL
5154character.
5155
5156E2fsck now uses stricter checks for directory entries in pass 2:
5157zero-length filenames are not allowed; neither are 8 byte long
5158directory entries.
5159
5160The debugfs "dirty" command now clears the filesystem valid bit.
5161(Previously this just set the dirty-as-in-needs-writing-out-to-disk
5162bit in the in-core superblock image.  The new functionality is more
5163what the user expects, and is more useful.)
5164
5165Added a debugging hook to test parallel fsck; if the environment
5166variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5167will be checked in parallel when they normally would not be.
5168
5169Programmer's notes:
5170-------------------
5171
5172Fixed some #ifdef's for compilation under the Hurd OS.
5173
5174Fixed minor W2K compatibility problems.
5175
5176Fixed some miscellaneous GCC warnings.
5177
5178
5179E2fsprogs 1.16 (October 22, 1999)
5180=================================
5181
5182Fixed a race condition bug in fsck; when printing a progress bar, if
5183checking multiple filesystems in parallel, it was possible for fsck to
5184send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5185handler, which would cause it to terminate with a signal 10.
5186
5187E2fsck now properly handles filesystems that have the
5188INCOMPAT_FILETYPE feature turned on.  It can be used to convert a
5189filesystem into using or not using FILETYPE feature.
5190
5191E2fsck now properly handles filesystems that have the IMAGIC feature
5192turned on (this is used on Linux AFS servers).
5193
5194The mke2fs program now creates filesystems that have the filetype and
5195sparse_superblock features enabled by default, unless it is run on a
5196pre-2.2 kernel.  These features are not supported by a pre-2.2 kernel,
5197so there is now a new flag -O which allows the user to specify with
5198which features she would like to create the filesystem; "mke2fs -O
5199none" will create a filesystsem compatible with 2.0 kernels.
5200
5201The tune2fs program now has a -O option which allows the user to set
5202and reset "safe" filesystem features.  Currently, the only ones which
5203allows to be modified are the filetype and sparse_superblock features.
5204Note setting or clearing either feature will require running e2fsck on
5205the filesystem afterwards.  (n.b. Clearing the sparse_superblock feature
5206requires that there is enough free space on the filesystem for the
5207extra superblocks which will be created by e2fsck.)
5208
5209Debugfs can now set and print filesystem features in the superblock
5210using the "features" command.  Dumpe2fs will print out the complete
5211set of features when listing the superblock.
5212
5213Dumpe2fs has new options -f (force) and -h (header-only).
5214
5215Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5216message to come up.  This could happen when decrementing or
5217incrementing a link count could result in an overflow.
5218
5219Fixed a bug in e2fsck where the block count on the lost+found
5220directory would not be properly incremented when the directory was
5221expanded to the point where an indirect block needed to be allocated.
5222
5223E2fsck now makes some additional sanity checks on the superblock to
5224avoid crashing or giving a memory allocation error if some of the
5225values in the superblock are unresonable (but the superblock otherwise
5226looks valid).
5227
5228Fixed a bug in e2fsck where a very badly corrupted filesystem might
5229require two passes to completely fix the filesystem.  This happened if
5230an inode claimed blocks that was part of the filesystem metadata
5231(typically, when garbage was written into an inode table or indirect
5232block, since this kind of filesystem corruption normally doesn't
5233happen otherwise).
5234
5235On the Alpha, glibc declares st_flags although it isn't actually used;
5236the configure script was improved to detect this case so that
5237e2fsprogs can avoid using the non-functional stat field.
5238
5239The manual pages were updated to use a more consistent formatting
5240style consistent with standard Unix man pages.  Mke2fs's man page
5241added documentation for a few previously undocumented options.
5242
5243Fixed minor display bugs in tune2fs and mke2fs.
5244
5245Programmer's notes:
5246-------------------
5247
5248Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5249
5250Added features to parse and print feature strings into the e2p library.  
5251(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5252
5253ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5254whose directory entries contain proper filetype information if the
5255filesystem supports it.
5256
5257ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5258the directory entry filetype information.  This is used to set the
5259directory entry filetype information if the filesystem supports it.
5260
5261Fixed a bug in ext2fs_expand_dir() where the block count in a
5262directory's inode would not be properly incremented when the directory
5263was expanded to the point where an indirect block needed to be
5264allocated.
5265
5266
5267E2fsprogs 1.15 (July 18, 1999)
5268==============================
5269
5270Add configuration checks so that e2fsprogs will compile cleanly on
5271Linux 2.3 kernels that have renamed i_version to i_generation.
5272
5273E2fsck now prints a progress/completion bar (and not just a simple
5274spinner) if the -C0 option is requested or if it receives a SIGUSR1
5275signal.  Fsck will automatically manage the (potentially muliple)
5276e2fsck processes to print completion bars if it is given a -C option,
5277with the right thing happening if multiple filesystems are being
5278checked in parallel.
5279
5280Mke2fs now has better automatic hueristics to determine the filesystem
5281parameters to be used for a particular filesystem.  Added a new option
5282-T which allows the user to specify how the filesystem is to be used,
5283which helps mke2fs do a better job selecting the filesystem parameters.
5284
5285Mke2fs now creates revision 1 filesystems by default, and with the
5286sparse superblock feature enabled.  The sparse superblock feature is
5287not understood by Linux 2.0 kernels, so they will only allow read-only
5288mounts of filesystems with this sparse superblocks.
5289
5290Fix bug where if /dev/null couldn't be opened (should never happen),
5291e2fsck would hang in a tight loop.
5292
5293Make e2fsck handle the case where /lost+found isn't a directory.
5294
5295E2fsck now uses mallinfo if it exists to get accurate statistics about
5296its memory usage.
5297
5298Fix bug in e2fsck where it wouldn't check to see if a disconnected
5299inode had any problems before connecting it to /lost+found.
5300
5301Add check to e2fsck so it makes sure that total number of inodes in
5302the filesystem is a sane number.
5303
5304Fix fencepost error when clearing an the end of the block bitmap which
5305caused the last block in the bitmap not to get cleared.
5306
5307Cleaned up a number of messages in e2fsck:
5308	* The message "Group's #'s copy of the group descriptor..."
5309		was fixed so that the correct number would be displayed.
5310	* Added missing space in the "disk write-protected" error messsage
5311	* Cleaned up the error message printed when a non-interactive
5312		e2fsck needs to abort a check because the filesystem
5313		appears to be mounted.
5314
5315Added a new command-line utility, uuidgen, which will create and print
5316a UUID.
5317
5318Make debugfs's icheck command more robust by checking to make sure an
5319inode has valid blocks before interarting over the inode's blocks.
5320
5321UUID generation now uses a random-based scheme whenever possible to
5322prevent potential privacy problems.
5323
5324Man pages for all of the UUID functions in the lirbary were added.
5325
5326Fixed bug in fsck so it won't coredump if a filesystem not in
5327/etc/fstab is given to it.
5328
5329Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5330that most of the other mount utilities understands.
5331
5332Mke2fs will make a filesystem even if it appears mounted if the force
5333option is given.
5334
5335Dumpe2fs has new command-line options which allow a filesystem expert
5336to specify the superblock and blocksize when opening a filesystem.
5337This is mainly useful when examining the remains of a toasted
5338filesystem.
5339
5340The badblocks program has been updated to display correctly on disks
5341with large block numbers.
5342
5343The badblocks program no longer gives spurious errors when errors
5344occur on non-block boundaries, which is common if the blocksize is
5345larger than 1k.
5346
5347Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5348MKE2FS_SYNC environment variable is set.  This is to work around a VM
5349bug in the 2.0 kernel.  I've heard a report that a RAID user was able
5350to trigger it even using a 2.2 kernel, but hopefully it will not be
5351needed for most Linux 2.2 users.
5352
5353Fixed miscellaneous documentation and man pages.
5354
5355Programmer's notes:
5356-------------------
5357
5358Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5359in e2fsck's pass1.c really should have been static.
5360
5361The return value of the uuid_compare() function was changed to make it
5362match with the convetions used by strcmp, memcmp, and Paul Leach's
5363UUID sample document.
5364
5365The "make depend" process has now been made more automated; it now
5366automatically word-wraps the dependencies, and only replaces source
5367Makefile.in if there has been a change in the dependencies.  Also, a
5368top-level "make depend" now recurses through all the subdirectories
5369automatically.
5370
5371The Makefile in .../util has been changed so that subst is built using
5372the native C compiler during a cross-compilation, since the subst
5373program is only used during the build process.  Also add an explicit
5374rule to build util/subst by cd'ing to the correct directory and
5375running Makefile.
5376
5377The man directories are defined in terms mandir, so that the configure
5378script can override the location of the manual pages.
5379
5380The config files have been updated to recognize new machine types for
5381both the i386 and alpha families.
5382
5383Fsck has been modified so that it will accurately create an
5384fsck_instance even when the noexecute flag is set.  This allows for
5385accurate debugging of the fsck pass structure.  Also, when the verbose
5386flag is given twice, fsck will print debugging information about when
5387fsck is waiting for jobs to finish.
5388
5389
5390E2fsprogs 1.14 (January 9, 1999)
5391================================
5392
5393Fix the fstab parsing code so that it can handle blank lines and
5394comment characters.  Also, missing pass numbers need to be treated as
5395zero.
5396
5397Fixed a bug in e2fsck where under some circumstances (when e2fsck
5398needs to restart processing after fixing an egregious inconsistency)
5399it would try to access already freed memory.
5400
5401E2fsck now prints non-printable characters in directory entries and
5402pathnames using '^' and 'M-' notation.
5403
5404Fixed chattr so that it will ignore symbolic links when doing
5405recursive descent traversals.  For both chattr and lsattr, no longer
5406print the version string unless the -V option is given.
5407
5408Allow the system administrator to directly specify the number of
5409inodes desired in the filesystem, for some special cases where this is
5410necessary.
5411
5412Fix portability problems so that e2fsprogs can be compiled under Linux
54131.2 systems and Solaris systems.
5414
5415Update the config.guess file with a more recent version that will
5416identify newer Linux platforms.
5417
5418Programmer's notes
5419------------------
5420
5421Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5422an inode number of zero is passed to them.
5423
5424E2fsprogs 1.13 (December 15, 1998)
5425==================================
5426
5427Fixed a bug in debugfs where an error messages weren't getting printed
5428when the ext2 library routines to read inodes returned errors in the
5429stat, cmri and rm commands.
5430
5431Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5432provided, it won't create an inode table smaller than the minimum
5433number of inodes required for a proper ext2 filesystem.
5434
5435Fsck now parses the /etc/fstab file directly (instead of using
5436getmntent()), so that it can distinguish between a missing pass number
5437field and pass number field of zero.  This caused problems for
5438diskless workstations where all of the filesystems in /etc/fstab have
5439an explicit pass number of zero, and fsck could not distinguish this
5440from a /etc/fstab file with missing pass numbers.
5441
5442E2fsck will create a /lost+found directory if there isn't one in the
5443filesystem, since it's safer to create the lost+found directory before
5444it's needed.
5445
5446Fixed e2fsck so that it would detect bogus immutable inodes which
5447happen to be sockets and FIFO files, and offer to clear them.
5448
5449If a filesystem has multiple reasons why it needs to be checked, and
5450one of the reasons is that it is uncleanly mounted, e2fsck will print
5451that as the reason why the filesystem is being checked.
5452
5453Cleaned up the output routines of mke2fs so that it doesn't overflow
5454an 80 column display when formating really big filesystems.
5455
5456Added a sanity check to e2fsck to make sure that file descriptors 0,
54571, 2 are open before opening the hard disk.  This avoids a problem
5458where a broken program might exec e2fsck with those file descriptors
5459closed, which would cause disastrous results if the kernel returns a
5460file descriptor for the block device which is also used by FILE *
5461stdout.
5462
5463Fixed up the e2fsck progress reporting functions so that the values
5464reliably reach 100% at the completion of all of the e2fsck passes.
5465
5466Fixed minor documentation bugs in man pages and usage messages.
5467
5468Programmer's notes:
5469-------------------
5470
5471Fixed a number of lint warnings in the ext2fs library and potential
5472portability problems from other OS's header files that might define
5473CPP macros for names like "max" and "min".
5474
5475ext2fs_badblocks_list_add() has been made more efficient when it needs
5476to grow the bad blocks list.
5477
5478Fixed a bug in e2fsck which caused it to dereference a freed pointer
5479just before exiting.
5480
5481Fixed the substition process for generating the mk_cmds and compile_et
5482scripts so that they will work outside of the build tree.
5483
5484Add sanity check to e2fsck so that if an internal routine
5485(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5486and causing a core dump.  This should never happen, but...
5487
5488E2fsprogs 1.12 (July 9, 1998)
5489==================================
5490
5491E2fsprogs now works with glibc (at least with the version shipped wtih
5492RedHat 5.0).  The ext2fs_llseek() function should now work even with
5493i386 ELF shared libraries and if llseek() is not present.  We also
5494explicitly do a configure test to see if (a) llseek is in libc, and
5495(b) if llseek is declared in the system header files.  (See standard
5496complaints about libc developers don't understand the concept of
5497compatibility with previous versions of libc.)
5498
5499The ext2fs library now writes out the block group number in each of
5500the superblock copies.  This makes it easier to automatically
5501determine the starting block group of the filesystem when the block
5502group information is trashed.
5503
5504Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5505which means that e2fsprogs will ignore the high 8 bits of the
5506directory entry's name_len field, so that it can be used for other
5507purposes.
5508
5509Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5510E2fsprogs will now support filesystems with 64-bit sized files.
5511
5512Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5513
5514Added new program "e2label", contributed by Andries Brouwer.  E2label
5515provides an easy-to-use interface to modify the filesystem label.
5516
5517Fixed bug so that lsattr -v works instead of producing a core dump.
5518
5519Fixed a minor bug in mke2fs so that all groups with bad superblock
5520backup blocks are printed (not just the first one).
5521
5522Mke2fs will check the size of the device, and if the user specifies a
5523filesystem size larger than the apparent size of the device it will
5524print a warning message and ask if the user wants to proceed.
5525
5526E2fsck has a new option -C, which sends completion information to the
5527specified file descriptor.  For the most part, this is intended for
5528programs to use, although -C 0 will print a spinning character to the
5529stdout device, which may be useful for users who want to see something
5530happening while e2fsck goes about its business.
5531
5532Fixed a bug in e2fsck which could cause a core dump when it needs to
5533expand the /lost+found directory, and sometimes the bitmaps haven't
5534been merged in.  Also fixed a related bug where ext2fs_write_dir_block
5535was used to write out a non-directory block.  (Which would be bad on a
5536non-Intel platform with byte swapping going on.)
5537
5538Fixed bug in e2fsck where it would print a "programming error" message
5539instead of correctly identifying where a bad block was in used when
5540the bad block was in a non-primary superblock or block group
5541descriptor.  Also fixed a related bug when sparse superblocks are in
5542use and there is a bad block where a superblock or block group
5543descriptor would have been in a group that doesn't include a
5544superblock.
5545
5546Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5547the block group descriptor table is corrupt, it was possible to try to
5548allocate a huge array, fail, and then abort e2fsck.
5549ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5550and subsitutes reasonable values if the descriptors are obviously bogus.
5551
5552If e2fsck finds a device file which has the immutable flag set and the
5553i_blocks beyond the normal device number are non-zero, e2fsck will
5554offer to remove it, since it's probably caused by garbage in the inode
5555table.
5556
5557When opening a filesystem, e2fsck specially checks for the EROFS error
5558code, and prints a specific error message to the user which is more
5559user friendly.
5560
5561If the filesystem revision is too high, change the e2fsck to print
5562that this is either because e2fsck is out of date, or because the
5563superblock is corrupt.  
5564
5565E2fsck now checks for directories that have duplicate '.' and '..'
5566entries, and fixes this corruption.
5567
5568E2fsck no longer forces a sync of the filesystem (with attendant sleep
5569calls) at all times.  The ext2fs_flush() function now performs a sync
5570only if it needed to write data blocks to disk.
5571
5572Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5573certain errors would not be properly reported.
5574
5575Updated and expanded a few points in the man pages which users
5576complained wheren't explicit enough.
5577
5578Added special case byte-swapping code if compiling on the PowerPC, to
5579accomodate the strange big-endian variant of the ext2 filesystem that
5580was previously used on the PowerPC port.
5581
5582
5583Programmer's notes:
5584-------------------
5585
5586Removed C++ keywords from the ext2fs libraries so that it could be
5587compiled with C++.
5588
5589E2fsck's internal organization has now been massively reorganized so
5590that pass*.c don't have any printf statements.  Instead, all problems
5591are reported through the fix_problem() abstraction interface.  E2fsck
5592has also been revamped so that it can be called as a library from a
5593application.
5594
5595Added new fileio primitives in libext2fs for reading and writing
5596files on an unmounted ext2 filesystem.  This interface is now used by
5597debugfs.
5598
5599Added a new libext2fs function for mapping logical block numbers of
5600a file to a physical block number.
5601
5602Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5603a block, zeros it, and updates the filesystem accounting records
5604appropriately.
5605
5606Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5607sets the padding of the bitmap to be all one's.  Used by e2fsck pass 5.
5608
5609The libext2fs functions now use a set of memory allocation wrapper
5610functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5611instead of malloc, free, and resize.  This makes it easier for us to
5612be ported to strange environments where malloc, et. al. aren't
5613necessarily available.
5614
5615Change the libext2fs fucntion to return ext2-specific error codes
5616(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5617and depending on the existence of system error codes (such as EEXIST
5618and ENOENT).
5619
5620Renamed io.h to ext2_io.h to avoid collision with other OS's header
5621files.
5622
5623Add protection against ext2_io.h and ext2fs.h being included multiple
5624times.
5625
5626The types used for memory lengths, etc. have been made more portable.
5627In generla, the code has been made 16-bit safe.  Added Mark
5628Habersack's contributed DOS disk i/o routines.
5629
5630Miscellaneous portability fixes, including not depending on char's
5631being signed.
5632
5633The io_channel structure has a new element, app_data, which is
5634initialized by the ext2fs routines to contain a copy of the filesystem
5635handle.
5636
5637ext2fs_check_directory()'s callback function may now return the error
5638EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5639really do the checking, despite the presence of the callback function.
5640
5641
5642E2fsprosg 1.11 (June 17, 1997)
5643==============================
5644
5645Fixed e2fsck to detect (previously ignored) conflicts between the
5646superblock or block group descriptors and block bitmaps, inode
5647bitmaps, and inode tables.
5648
5649Fixed bug in e2fsck so that when the message printed out when a block
5650or inode bitmap conflicts with other data, it has the correct group
5651number.
5652
5653Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5654to badblocks.  This meant that not all of the filesystem was being
5655tested for bad blocks! 
5656
5657Fixed an array boundary overrun case which cropped up in
5658ext2fs_badblocks_list_test when a user tried running "mke2fs -c 
5659-b 4096".
5660
5661Adjusted the number of columns printed by mke2fs when displaying the
5662superblock backups to avoid running over 80 columns when making a
5663really big filesystem.
5664
5665Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5666dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5667fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5668
5669Programmer's notes:
5670-------------------
5671
5672Fixed install rule in lib/ss so that ss_err.h is actually getting
5673installed.
5674
5675Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5676bassed back to the caller.
5677
5678Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5679setting the current inode number (which meant this function wasn't
5680working at all).
5681
5682Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5683blocks in the bitmap when increasing the size of the bitmap.
5684
5685Changed the initial number of blocks allocated by ext2fs_init_dblist()
5686to be more realistic.
5687
5688Added a new function ext2fs_allocate_group_table, which sets up the
5689group descriptor information (and allocates inode and block bitmaps,
5690and inode tables for a particular group).  The function was created by
5691factoring out code form ext2fs_allocate_tables().
5692
5693Added a new function ext2fs_move_blocks which takes a bitmap of the
5694blocks to be moved, and moves them to another location on the
5695boardboard.
5696
5697Make the unix_io channel's io_channel_flush implementation calls sync()
5698to to flush the kernel buffers to disk.
5699
5700Added a new function ext2fs_dblist_count returns the number of
5701directory blocks in dblist.
5702
5703
5704E2fsprogs 1.10 (April 24, 1997)
5705===============================
5706
5707Mke2fs once again defaults to creating revision #0 filesystems, since
5708people were complaining about breaking compatibility with 1.2 kernels.
5709Warning messages were added to the mke2fs and tune2fs man pages that
5710the sparse superblock option isn't supported by most kernels yet (1.2
5711and 2.0 both don't support parse superblocks.)
5712
5713Added new flag to mke2fs, -R <raid options>, which allows the user to
5714tell mke2fs about the RAID configuration of the filesystem.  Currently
5715the only supported raid option is "stride" which specifies the width
5716of the RAID stripe.
5717
5718Fixed bug in e2fsck where pass1b would bomb out if there were any
5719blocks marked bad in the inode table.
5720
5721Fixed rare bug in mke2fs where if the user had a very unlucky number
5722of blocks in a filesystem (probability less than .002) the resulting
5723filesystem would be corrupt in the last block group.
5724
5725Fixed bug where if e2fsck tried to allocate a block to fix a
5726filesystem corruption problem and the filesystem had no free blocks,
5727ext2fs_new_block() would loop forever.
5728
5729The configure script now checks explicitly to see if "-static" works,
5730since that can't be assumed to be true --- RedHat doesn't install
5731libc-static by default.
5732
5733Fixed bug in libext2's block iterator functions where under some
5734cirmcustances, file with holes would cause the bcount parameter to the
5735callback function to be incorrect.  This bug didn't affect any of
5736e2fsprogs programs, but it was discovered by Paul Mackerras, the
5737author of the PPC boot loader.
5738
5739Removed use of static variables to store the inode cache in libext2fs.
5740This caused problems if more than one filesystem was accessed via
5741libext2fs (static variables in libraries are generally a bad idea).
5742Again, this didn't affect e2fsprogs programs, but it was discovered by
5743Paul Mackerras.
5744
5745Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5746will compile cleanly with 1.2.13 kernels (even with a.out shared
5747libraries!)
5748
5749Programmer's notes:
5750-------------------
5751
5752Added new functions to duplicate an ext2 filesystem handle, and its
5753associated substructure.  New functions: ext2fs_dup_handle(),
5754ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5755Other structures, such as the io_channel and the inode_cache, now have
5756a ref count so that they only get freed when they are no longer used
5757by any filesystem handle.  (These functions were added as part of the
5758development effort for an ext2 resizer).
5759
5760E2fsprogs 1.09 (April 14, 1997)
5761===============================
5762
5763Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5764accidentally introduced in the 1.08 release.  The overhead calculation
5765was accidentally removed, which caused ext2fs_initialize() to not
5766notice when the filesystem size needed to be adjusted down because
5767there wasn't enough space in the last block group.
5768
5769Fixed bug in version parsing library routine; it was always parsing
5770the library version string, instead of using the passed-in string.
5771
5772Clarified chattr man page.
5773
5774E2fsprogs 1.08 (April 10, 1997)
5775===============================
5776
5777E2fsck 1.07 was very slow when checking very large filesystems with a
5778lot of files that had hard links (i.e., news spools).  This was fixed
5779by seriously revamping the icount abstraction.  Added a formal test
5780suite for the icount abstraction.
5781
5782Debugfs now has a "-l" option to the "ls" command, which lists the
5783inode number, permissions, owner, group, size, and name of the files
5784in the directory.
5785
5786Fix a bug in e2fsck where when a directory had its blocks moved to
5787another location during the pass 1b processing, the directory block
5788list wasn't updated, so pass 2 wouldn't check (and correct) the
5789correct directory block.
5790
5791E2fsck will now treat inodes which contain blocks which are claimed by
5792the filesystem metadata by treating them as multiply claimed blocks.
5793This way, the data in those blocks can be copied to a new block during
5794the pass 1b--1d processing.
5795
5796E2fsck will attempt to determine the correct superblock number and
5797display it in the diagnostic and warning messages if possible.
5798
5799Add support for a new (incompatible) feature, "sparse_super".  This
5800feature reduces the number of blocks which contain copies of backup
5801superblocks and block group descriptors.  (It is only an incompatible
5802feature because of a bug in ext2_free_blocks.)  mke2fs and tune2fs now
5803support a new -s option; e2fsck will recognize filesystems built with
5804this feature turned on.
5805
5806E2fsck now checks the library to make sure is the correct version,
5807using new library functions.  (This helps to diagnose incorrectly
5808installed e2fsprogs distributions.)
5809
5810Dumpe2fs now prints more information; its now prints the the
5811filesystem revision number, the filesystem sparse_super feature (if
5812present), the block ranges for each block group, and the offset from
5813the beginning of the block group.
5814
5815Mke2fs now distributes the inode and block bitmap blok so that the
5816won't be concentrated in one or two disks in RAID/striping setups.
5817Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5818choose the largest blocks per group that be chosen.  (For 2k blocks,
5819you can have up to 16384 blocks/group; for 4k blocks, you can have up
5820to 32768 blocks/group.)  Previously mke2fs would not allow
5821specification of more than 8192 blocks per group, even if you were
5822using a 2k or 4k block group.
5823
5824Programmer's notes:
5825-------------------
5826
5827Added a new function ext2fs_create_icount2() which takes a "hint"
5828argument.  This hint argument presets the icount array with the list
5829of inodes which actually need to be in the icount array.  This really
5830helps to speed up e2fsck.
5831
5832Added a new function ext2fs_icount_validate() which checks the rep
5833invariant for the icount structure.  This is used mostly for testing.
5834
5835The error mesasage given when a bad inode number is passed to
5836test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5837EXT2FS_UNMARK_ERROR).
5838
5839Added a new function ext2fs_set_dir_block which sets the block of a
5840dblist entry, given the directory inode and blockcnt.
5841
5842Added a new function ext2fs_get_library_version() which returns the
5843current library version, and ext2fs_parse_version_string() which
5844returns a version number based on a e2fsprogs version string.
5845
5846The icount functions will return EINVAL if the passed in inode number
5847is out of bounds.
5848
5849E2fsprogs 1.07 (March 9, 1997)
5850==============================
5851
5852E2fsck is now uses much less memory when checking really large
5853filesystems (or rather, filesystems with a large number of inodes).
5854Previously a filesystem with 1 million inodes required 4 megabytes of
5855memory to store inode count statistics; that storage requirement has
5856now been reduced to roughly half a megabyte.
5857
5858E2fsck can now properly deal with bad blocks appearing inside the
5859inode table.  Instead of trying to relocate the inode table (which
5860often failed because there wasn't enough space), the inodes in the bad
5861block are marked as in use.
5862
5863E2fsck will automatically try to use the backup superblocks if the
5864primary superblocks have a bad magic number or have missing meta-data
5865blocks (or meta-data blocks which are out of range).
5866
5867E2fsck's pass 3 has been made more efficient; most noticeable on
5868filesystems with a very large number of directories.
5869
5870Completely revamped e2fsck's system of printing problem reports.  It
5871is now table driven, to make them more easily customizeable and
5872extendable.  Error messages which can be printed out during preen mode
5873are now one line long.
5874
5875Fixed e2fsck's filesystem swapping code so that it won't try to swap
5876fast symbolic links or deleted files.
5877
5878Fixed e2fsck core dumping when fixing a filesystem which has no
5879directories (not even a root directory).
5880
5881Added a check to e2fsck to make sure that the length of every
5882directory entry is a multiple of 4 (since the kernel complains if it
5883isn't).
5884
5885Added a check to e2fsck to make sure that a directory entry isn't a
5886link to the root directory, since that isn't allowed.
5887
5888Added a check to e2fsk to now make sure the '.' and '..' directory
5889entries are null terminated, since the 2.0 kernel requires it.
5890
5891Added check to write_bitmaps() to make sure the superblock doesn't get
5892trashed if the inode or block bitmap is marked as being block zero.
5893
5894Added checking of the new feature set fields in the superblock, to
5895avoid dealing with new filesystem features that this package wasn't
5896set up to handle.
5897
5898Fixed a fencepost error in ext2fs_new_block() which would occasionally
5899try to allocate a block beyond the end of a filesystem.
5900
5901When the UUID library picks a random IEEE 802 address (because it
5902can't find one from a network card), it sets the multicast bit, to
5903avoid conflicting with a legitimate IEEE 802 address.
5904
5905Mke2fs now sets the root directory's owner to be the real uid of the
5906user running mke2fs.  If the real uid is non-zero, it also sets
5907the group ownership of the root directory to be the real group-id of
5908the user running mke2fs.
5909
5910Mke2fs now has more intelligent error checking when it is given a
5911non-existent device.
5912
5913When badblocks is given the -vv option, it now updates the block that
5914it is currently testing on every block.
5915
5916Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5917currently correctly if PATH wasn't already set.
5918
5919Shared libraries now built with dependencies.  This allows the shared
5920library files to be used with dlopen(); it also makes the transition
5921to libc 6 easier, since ld.so can tell which libc a particular shared
5922library expects to use.
5923
5924Programmer's notes:
5925-------------------
5926
5927Added new abstraction (defined in dblist.c) for maintaining a list of
5928blocks which belongs to directories.  This is used in e2fsck and other
5929programs which need to iterate over all directories.
5930
5931Added new functions which test to see if a contiguous range of blocks
5932(or inodes) are available.  (ext2fs_*_bitmap_range).
5933
5934Added new function (ext2_inode_has_valid_blocks) which returns true if
5935an inode has valid blocks.  (moved from e2fsck code).
5936
5937Added new function (ext2fs_allocate_tables) which allocates the
5938meta-data blocks as part of initializing a filesystem.  (moved from
5939mke2fs code).
5940
5941Added a new I/O manager for testing purposes.  It will either allow a
5942program to intercept I/O requests, or print debugging messages to
5943trace the activity of a program using the I/O manager.
5944
5945The badblocks_list functions now store the bad blocks in a sorted
5946order, and use a binary search to speed up badblocks_list_test.
5947
5948The inode scan function ext2fs_get_next_inode() may now return a soft
5949error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5950those cases where part of an inode table is missing or there is a bad
5951block in the inode table.  
5952
5953Added a new function (ext2fs_block_iterate2) which adds new arguments to
5954the callback function to return a pointer (block and offset) to the
5955reference of the block.
5956
5957Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5958application to jump to a particular block group while doing an inode
5959scan.
5960
5961The badblocks list functions were renamed from badblocks_* to
5962ext2fs_badblocks_*.  Backwards compatibility functions are available
5963for now, but programs should be modified to use the new interface.
5964
5965Some of the library functions were reorganized into separate files to
5966reduce the size of some programs which statically link against the
5967ext2 library.
5968
5969Put in some miscellaneous fixes for the Alpha platform.
5970
5971
5972E2fsprogs 1.06 (October 7, 1996)
5973================================
5974
5975Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5976smash the backup copies in ext2fs_close().  (The problem was that when
5977e2fsck -p discovered the problem, while it was closing the filesystem
5978and exiting, it was also blowing away the backup superblocks on the
5979disk, which was less than friendly.)  We now make it the case that we
5980only write out the backup superblock and the back block descriptors if
5981the filesystem is completely free from problems.
5982
5983Fixed a bug in block_interate in the lib/ext2fs library which caused
5984e2fsck to fail on GNU Hurd-created filesystems.
5985
5986Add support for Linux/FT's bootloader, which actually uses
5987EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5988to clear the inode.
5989
5990Add support for the "A" (no atime update) attribute.  (Note: this
5991attribute is not yet in production kernels.)
5992
5993The test suite is not automatically run when doing a "make all" from
5994the top level directory.  Users should manually run "make check" if
5995they wish to run the test suite.
5996
5997Upon a preenhalt(), make the printed message more explicit that
5998running e2fsck "MANAULLY" means without the -p or -a options.
5999
6000In e2fsck, if a disconnected inode is zero-length, offer to clear it
6001instead of offering to connect it to lost+found.
6002
6003In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6004e2fsck to be run over it, change e2fsck to explicitly display this
6005fact.
6006
6007For dumpe2fs and e2fsck, cause the -V option to print out which
6008version of the ext2fs library is actually getting used.  (This will
6009help detect mismatches of using a 1.06 utility with a 1.05 library,
6010etc.)
6011
6012Programmers' notes:
6013-------------------
6014
6015EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6016the naming convention.
6017
6018In ext2fs_initialize(), make sure the description for the inode bitmap
6019is correctly initialize.
6020
6021Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6022
6023E2fsprogs 1.05 (September 7, 1996)
6024==================================
6025
6026Add support for new fields in the ext2 superblock --- volume name,
6027volume UUID, and last mounted field.  Dumpe2fs displays these fields,
6028tune2fs and mke2fs allows you to set them.  E2fsck will automatically
6029generate a UUID for those volumes that don't have them.  
6030
6031Put in support for e2fsck to recognize HURD specific ext2 features ---
6032most notably, the translator block.  The e2fsprogs tools will now use
6033the creator_os field in the superblock to correctly handle different
6034OS-specific variants of the ext2 filesystem.
6035
6036E2fsck now fixes inodes which have a the deletion time set, but which
6037have a non-zero i_link_count field by offering to clear the deletion
6038time.  Previously e2fsck assumed that the inode was deleted (per 0.3c
6039ext2 kernel behavior) and offered to unlink the file.
6040
6041If e2fsck sets the clean bit, but nothing else, set the exit code
6042FSCK_NONDESTRUCT.  After all, e2fsck did fix a filesystem error --- it
6043set the filesystem valid bit when it was previously cleared.  :-) This
6044was needed to make the HURD fsck driver happy.
6045
6046If the  user  refuses to attach an  unattached  inode, e2fsck  will no
6047longer set the inode's link count.  Otherwise, the  inode would end up
6048getting marked as unused, which might cause loss of data later.
6049
6050Make the message issued by e2fsck when the superblock is corrupt less
6051confusing for users.  It now mentions that another reason for the
6052"corrupt superblock" message might be that the partition might not be
6053an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6054
6055Make the libext2 library more robuest so that e2fsck won't coredump on
6056an illegal superblock where the blocksize is zero.  (f_crashdisk is
6057the test case).
6058
6059By default, create filesystems where the default checkinterval is 6
6060months (180 days).  Linux servers can be robust enough that 20 reboots
6061can be a long, long time.
6062
6063Added configure flag --enable-old-bitops, which forces the bitops to
6064use the old (native) bitmask operations.  By default on the sparc
6065platform, the standard ext2 bit ordering is now used.
6066
6067Added a new feature to e2fsck to byte-swap filesystems; this can be
6068used to convert old m68k filesystems to use the standard byte-order
6069storage for the superblock, inodes, and directory blocks.  This
6070function is invoked by using the '-s' option to e2fsck.
6071
6072Debugfs's "dump" command has been enhanced so that it writes out the
6073exact size of the file so that the nulls at the end of the file are
6074eliminated.  The command also accept a new "-p" option which will
6075attempt preserve to preserve the ownernship, permissions, and
6076file modification/access times.
6077
6078Debugfs has two new options, -f and -R.  The -R option allows the user
6079to execute a single debugfs command from the command line.  The -f
6080option allows the user to specify a "command file" containing debugfs
6081commands which will get executed.
6082
6083Dumpe2fs now pretty prints the check interval, instead of just
6084printing the check interval as a number of seconds.
6085
6086Fix bugs in debugfs: the params command when no filesystem is opened
6087no longer causes a core dump.  It is now possible to unlink a file
6088when a pathame containing a '/' is specified.
6089
6090Tune2fs has a new -C option which sets the number of times the
6091filesystem has been mounted.
6092
6093Fix the chattr '-v' option so that it actually works.  Chattr was
6094being buggy about the -v option parsing.
6095
6096Programmers' notes:
6097-------------------
6098
6099The directory lib/uuid contains a set of library routines to generate
6100DCE compatible UUIDs.  
6101
6102Extended ext2fs_namei() to handle symbolic links.  Added new function
6103ext2fs_nami_follow() which will follow last symbolic link in the case
6104where the pathname points to a sym link.
6105
6106The ext2fs_block_iterate function will now return the HURD translator
6107block, if present.  The new flag BLOCK_FLAG_DATA_ONLY will cause the
6108iterator to return data blocks only.  The ext2fs.h file now defines
6109constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6110BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6111count field of the iterator callback function.
6112
6113The test script driver now takes an optional second argument, which is
6114the test case to be run.  This allows you to run a test case without
6115needing to run the entire test suite.
6116
6117On Linux ELF systems, install the .so files in the correct places
6118(/usr/lib).  The .so files must be stored in the same directory as the
6119.a files.
6120
6121Fixed miscellaneous HURD compilation issues with header file being
6122included in the right order.
6123
6124Fixed debugfs so that it resets optind to zero, not one, since setting
6125optind to zero is more correct.
6126
6127
6128E2fsprogs 1.04 (May 16, 1996)
6129=============================
6130
6131First "official" (1.03 was a limited release only) to support building
6132e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6133kernels).
6134
6135This package includes a RPM specs file, that it can be built using the
6136RedHat Package Manager.
6137
6138E2fsck now prints a hint that if there are lots of incorrectly located
6139inode bitmaps, block bitmaps, and inode table blocks, the user might
6140want to try using e2fsck -b 8193 first, to see if that fares any
6141better.
6142
6143For ext2 filesystem written with the hurd, debugfs will now print out
6144the translator field when printing an inode structure.
6145
6146Lots of miscellaneous linking/installation cleanups:
6147
6148  Libraries are now linked using a relative pathname, instead of
6149  relying on -L working correct.  It doesn't, in many cases, including
6150  current versions of GNU ld.  This guarantees that the build tree is
6151  linking with the right libraries, instead of the ones installed in
6152  /usr/lib.
6153
6154  Header files, man pages, and the et/ss shell scripts are now
6155  generated using a custom substitution script, instead of relying on
6156  the configure script.  This prevents needless recompilation of
6157  files; in addition, the custom substitution script is much faster.
6158
6159  e2fsck may now be linked dynamically, by using the
6160  --enable-dynamic-e2fsck flag to configure.  This is not recommended,
6161  since it increases e2fsck's dependence on other files, but some
6162  people need to save disk space, and other critical programs on their
6163  systems were being linked dynamically anyway.
6164
6165  Programs such as fsck which didn't need to be linked against
6166  libext2fs (or mke2fs which didn't need to be linked against libe2p)
6167  only link against libraries they actually need.  Otherwise, those
6168  programs would require the presense of libraries that otherwise
6169  could be removed from a rescuse diskette.
6170
6171  The ss include files are now installed correctly so they can
6172  actually be used by another package.
6173
6174  If the profiling libraries are built, they are now installed on a
6175  "make install-libs".
6176
6177
6178E2fsprogs 1.03 (March 27, 1996)
6179===============================
6180
6181Change the m68k bit numbering for bitmasks to match the bit numbering
6182used by all other ext2 implementations.  (This change was requested by
6183the m68k kernel development team.)
6184
6185Support (in-development) filesystem format revision which supports
6186(among other things) dynamically sized inodes.
6187
6188Fixed a bug in the ext2 library so that an intelligent error is
6189returned if mke2fs is run with a ridiculously small number of blocks
6190for a partition.
6191
6192Fixed a bug in the ext2 library which required that the device be
6193openable in read/write mode in order to determine its size.  This
6194caused e2fsck -n to require read/write access when it was not
6195previously necessary.
6196
6197Fixed a bug in e2fsck which casued it to occasionally fail the test
6198suite depending on which version of the floating point library it was
6199using.
6200
6201Fixed a bug in e2fsck so that it now halts with a fatal error when
6202certain superblock consistency checks fail.  Previously it continued
6203running e2fsck, with some potential confusing/damaging consequences.
6204
6205Added new flag to fsck which allows the root to be checked in parallel
6206with other filesytems.  This is not the safest thing in the world to
6207do, but some system administrators really wanted it.
6208
6209Fixed -Wall flames in lib/ss.
6210
6211
6212E2fsprogs 1.02 (January 16, 1996)
6213=================================
6214
6215Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6216
6217Change e2fsck to print statistics of how many non-contiguous files are
6218on the system.  Note that a file which is larger than 8k blocks, it is
6219guaranteed to be non-contiguous.
6220
6221In mke2fs, print a warning message if a user tries to format a whole
6222disk (/dev/hda versus /dev/hda1).  If a user really wants to format a
6223whole disk, the -F (force) option forces mke2fs to format a whole disk
6224as a filesytem.
6225
6226Fix a bug in fsck where in some cases it might start checking
6227partitions in the next pass before it finishes checking partitions in
6228the current pass.  This still won't cause two partitions on the same
6229disk will be checked, so it's rarely a problem in real life.
6230
6231Patch lsattr so that it won't hang when checking a named pipe.
6232
6233Minor compilation fixes:
6234	* Fix the order of libraries that were linked in debugfs.
6235	* Allow the sources to be compiled with -ansi turned on.
6236
