1 E2fsprogs 1.41.14 (December 22, 2010)
2 =====================================
4 Fix spurious complaint in mke2fs where it would complain if the file
5 system type "default" is not defined in mke2fs.conf.
7 The resize2fs program will no longer clear the resize_inode feature
8 when the number reserved group descriptor blocks reaches zero. This
9 allows for subsequent shrinks of the file system to work cleanly for
12 The resize2fs program now handles devices which are exactly 16T;
13 previously it would give an error saying that the file system was too
16 E2fsck (and the libext2fs library) will not use the extended rec_len
17 encoding for file systems whose block size is less than 64k, for
18 consistency with the kernel.
23 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
24 been fixed. (Addresses Sourceforge Bug: #3138115)
26 The ext2fs_block_iterator2() function passed an incorrect ref_offset
27 to its callback function in the case of sparse files. (Addresses
28 Sourceforge Bug: #3081087)
30 Fix some type-punning warnings generated by newer versions of gcc.
33 E2fsprogs 1.41.13 (December 13, 2010)
34 =====================================
36 E2fsck now supports the extended option "-E journal_only", which
37 causes it to only do a journal replay. This is useful for scripts
38 that want to first replay the journal and then check to see if it
41 E2fsck will now support UUID= and LABEL= specifiers for the -j option
42 (which specifies where to find the external journal). (Addresses
45 E2fsck now has support for the problems/<problem code>/force_no
46 configuration option in e2fsck.conf, which forces a problem to not be
49 Dumpe2fs will now avoid printing large negative offsets for the bitmap
50 blocks and instead print a message which is a bit more helpful for
53 Mke2fs will now check the file system type (specified with the -t
54 option) to make sure it is defined in the mke2fs.conf file; if it is
55 not, it will print an error and abort. If the usage type (specified
56 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
57 warning but will continue. (Addresses Debian Bug #594609)
59 Clarified error message from resize2fs clarifying that on-line
60 shrinking is not supported at all. (Addresses Debian Bug #599786)
62 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
63 displayed. (Addresses Debian Bug #555456)
65 E2fsck will open the external journal in exclusive mode, to prevent
66 the journal from getting truncated while it is in use due to a user
67 accidentally trying to run e2fsck on a snapshotted file system volume.
68 (Addresses Debian Bug #587531)
70 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
73 The tune2fs program can now set the uninit_bg feature without
76 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
77 default mount options settings which were added in 2.6.35.
79 The e2fsck and dumpe2fs programs now support the new ext4 superblock
80 fields which track where and when the first and most recent file
81 system errors occurred. These fields are displayed by dumpe2fs and
82 cleared by e2fsck. These new superblock fields were added in 2.6.36.
84 Debugfs now uses a more concicse format for listing extents in its
85 stat command. This format also includes the interior extent tree
86 blocks, which previously was missing from stat's output for
89 Debugfs has a new option, -D, which will request Direct I/O access of
92 Mke2fs will skip initializing the inode table if a device supports
93 discard and the discard operation will result in zero'ed blocks.
95 Badblocks will now correctly backspace over UTF-8 characters when
96 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
97 Debian Bugs #583782 and #587834)
99 E2freefrag will now display the total number of free extents.
101 Resize2fs -P no longer requires a freshly checked filesystem before
102 printing the minimum resize size.
104 Fixed a floating point precision error in a binary tree search routine
105 that can lead to seg fault in e2fsck and resize2fs.
107 Fixed a bug in e2fsck where if both the original and backup superblock
108 are invalid in some way, e2fsck will fail going back to the original
109 superblock because it didn't close the backup superblock first, and
110 the exclusive open prevented the file system from being reopened.
112 Fixed a big in e2freefrag which caused getopt parsing to fail on
113 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
115 Clarified 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")
117 results in a more understandable explanation to the user.
119 Mke2fs now displays the correct valid inode ratio range when
120 complaining about an invalid inode ratio specified by the user.
122 Mke2fs now understands the extended option "discard" and "nodiscard",
123 and the older option -K is deprecated. The default of whether
124 discards are enabled by default can be controled by the mke2fs.conf
127 Mke2fs's handling of logical and physical sector sizes has been
128 improved to reflect the fact that there will be some SSD's with 8k and
129 16k physical sectors arriving soon. Mke2fs will no longer force block
130 size to be the physical sector size, since there will be devices where
131 the physical sector size is larger than the system's page size, and
132 hence larger than the maximal supported block size. In addition, if
133 the minimal and optimal io size are not exported by the device, and
134 the physical sector size is larger than the block size, the physical
135 sector size will be used to set the Raid I/O optimization hints in the
138 E2fsck will now display a better, more specific error message when the
139 user enters a typo'ed device name, instead of blathering on about
140 alternate superblocks.
142 Fixed various Debian Packaging Issues
144 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
145 #589345, #591083; Addresses Launchpad Bug: #505719)
147 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
148 Polish, Swedish, and Vietnamese translations.
154 Fix a dependency definition for the static and profiled blkid
155 libraries which could cause compile failures in some configurations.
156 (Addresses Debian Bug: #604629)
158 Add support for Direct I/O in the Unix I/O access layer.
160 Fixed a memory leak in the Unix I/O layer when changing block sizes.
162 Fixed minor memory leaks in mke2fs.
164 Added a new function to the ext2fs library, ext2fs_get_memalign().
166 The tst_super_size test program will check to make sure the superblock
167 fields are correctly aligned and will print them out so they can be
168 manually checked for correctness.
170 Fixed some makefile dependencies for test programs in lib/ext2fs.
172 Reserved the feature flags and superblock fields needed for the Next3
175 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
176 EXT4_INCOMPAT_EA_INODE.
179 E2fsprogs 1.41.12 (May 17, 2010)
180 ================================
182 Mke2fs now gives a correct error message if the external journal
183 device is not found. (Addresses Red Hat Bug #572935)
185 Resize2fs -P will now refuse to print a minimum size if the file
186 system is not clean. Previously it would go ahead and print a minimum
187 size anyway, which might not be correct, leading to user confusion.
189 E2fsck now tests for extents that begin at physical block 0 and
190 rejects them as invalid. (Addresses Google Bug: #2573806)
192 Fixed a bug in e2fsck which could cause it to crash when trying to
193 remove an invalid extent and the block bitmaps hadn't yet been loaded.
194 (Addresses SourceForge Bug: #2971800)
196 E2fsck now will completely skip time-based checks if the system clock
197 looks insane or the option broken_system_clock is set in
200 E2fsck would previously report an i_blocks corruption for a 4T file
201 created using posix_fallocate; this bug has been fixed.
203 E2fsck will now correctly mark a sparse journal as invalid and will
204 delete and recreate the journal to address the problem.
206 E2fsck would previously incorrectly ask the user whether she would
207 like to abort the file system check after finding a problem --- and
208 then abort regardless of the user's answer. This is annoying, and
211 E2fsck can now continue even if it fails to recreate the resize
212 inode; previously it would just abort the file system check
215 E2fsck could potentially remove directory entries for inodes found in
216 the unused region of the inode table; this would generally happen on
217 ext4 file systems that do not use journaling. This bug has been fixed
218 by not clearing these directory entries once it has been established
219 that bg_unused_inodes may not be trustworthy; once pass #2 has been
220 completed, e2fsck will restart the file system check from the
221 beginning, and then it will be safe to delete any directory entries
222 pointing to inodes that appear to be deleted. (Addresses Google Bug:
225 E2fsck will not try to set the block group checksums if the user
226 cancels the fsck with a control-C. It's a bad idea to set the
227 checksums if e2fsck hasn't been completed, and it often results an the
228 error message, "Inode bitmap not loaded while setting block group
229 checksum info". (Addresses Launchpad Bug: #582035)
231 The mke2fs program now queries the kernel for the physical as well as
232 the logical sector size, and will not allow a blocksize below the
233 logical, and will strongly encourage a blocksize at least as big as
234 the physical blocksize. This is needed for 4k sector drives that
235 emulate 512 byte sector sizes.
237 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
238 rarely needed, but it is a legal value.
240 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
241 not needed, and offer to clear it; this is a sign of a kernel bug, but
242 more importantly, some released kernels may crash when this situation
243 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
245 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
246 i_size is correct. (Kernels starting with 2.6.34 will set
249 The com_err library will now only output ^M (a CR character) when the
252 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
253 and Vietnamese translations.
255 Fixed various Debian packaging issues --- see debian/changelog for
256 details. (Addresses Debian Bugs: #571247, #563487)
262 The regression test suite now uses its own mke2fs.conf file, so that
263 downstream distributions want change the mke2fs.conf file which is
264 distributed in the RPM or dpkg file, without worrying about screwing
265 up the regression test results.
267 Always build namei.o so that building with configure --disable-debugfs
268 works correctly. Long-term, if we care about reduced e2fsprogs
269 builds, we need a more general solution for deciding what .o files are
270 needed 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)
274 Add configure options --enable-symlink-build and
275 --enable-symlink-install, which allow e2fsprogs be built using
276 symlinks instad of hard links, and to be installed using symlinks
277 instead of hard links, respectively. It is useful when the file
278 system where the build is taking place, or the file system where
279 e2fsprogs is installed, can't handle hard links for some reason.
280 (Addresses Sourceforge Bug: #1436294)
282 Fixed compile warning in mke2fs.c.
285 E2fsprogs 1.41.11 (March 14, 2010)
286 ==================================
288 E2fsck will no longer give a fatal error and abort if the physical
289 device has been resized beyond 2**32 blocks. (Addresses Launchpad
292 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
293 the allocation status of the block <blk>. (Addresses Debian Bug:
296 E2fsck now prints a much more emphatic and hopefully scary message
297 when a file system is detected as mounted while doing a read/write
298 check of the filesystem. Hopefully this will dissuade users from
299 thinking, "surely that message doesn't apply to *me*" :-(
301 E2fsck -n will now always open the file system read-only. We now
302 disallow certain combination of options which previously were manual
303 exceptions; this is bad because it causes users to think they are
304 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
305 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
307 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
308 it detected a badly aligned partition. Unfortunately, this broke some
309 distribution installation scripts, so it now just prints the warning
310 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
311 Launchpad Bug: #530071)
313 Mke2fs would take a long time to create very large journal files for
314 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
317 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
318 2.6.34 kernels to make e2fsck not complain about blocks deliberately
319 fallocated() beyond an inode's i_size.
321 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
322 e2fsck -fD can corrupt non-indexed directories when are exists one or
323 more file names which alphabetically sort before ".". This can happen
324 with ext2 filesystems or for small directories (take less than a lock)
325 which contain filenames that begin with a space or some other
326 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
333 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
336 The libcom_err function now has support for Heimdal's com_right_r
337 function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
341 E2fsprogs 1.41.10 (February 7, 2010)
342 ====================================
344 Fix resize2fs bug which causes it to access invalid memory.
346 Add libss support for libreadline.so.6.
348 Fix e2fsck's check for extent-mapped directory with an incorrect file
351 Add new e2fsck.conf configuration option, default/broken_system_clock
352 to support systems with broken CMOS hardware clocks. Also, since too
353 many distributions seem to have broken virtualization scripts now,
354 e2fsck will by default accept dates which are off by up to 24 hours by
355 default. (Addresses Debian Bugs: #559776, #557636)
357 Fix a bug where mke2fs may not use the best placement of the inode
358 table when there is only room for a single block group in the last
361 E2fsck is now smarter when it needs to allocate blocks in the course
362 of fixing file system problems. This reduces the number of spurious
363 differences found in pass #5.
365 E2fsck will no longer rehash directories which fit in a single
368 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
369 sparse directories which use extents).
371 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
373 Fix a bug in filefrag where on platforms which can allow file systems
374 with 8k blocks, that it doesn't core dump when it sees a file system
375 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
378 E2fsck will correctly fix directories that are have an inaccurate
379 i_size as well as other problems in a single pass, instead of
380 requiring two e2fsck runs before the file system is fully fixed.
382 Fix e2fsck so it will correctly find and detect duplicate directory
383 entries for non-indexed directories. ( Addresses Sourceforge Bug:
386 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
387 thinly-provisioned storage device. This can be disabled using the -K
390 Enhance libext2fs so it works around bug in Linux version 2.6.19
391 and earlier where the /proc/swaps file was missing the header on
394 Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
395 was missing the header on the first line.
397 Fix some big-endian bugs in e2fsck and libext2fs.
399 Fix resize2fs so it works correctly on file systems with external
400 journals instead of failing early with the error "Illegal inode
403 Fix libss so that it does not seg fault when using a readline library
404 which does not supply a readline_shutdown() function.
406 Updated dumpe2fs's usage message so it correctly gives the right
407 arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
408 (Addresses Launchpad Bug: #448099)
410 Teach libext2fs to ignore the high 32 bits of the i_blocks field
411 when huge_file file system feature is set, but the inode does not
412 have the HUGE_FILE_FL flag set.
414 Fix e2fsck's handling of 64-bit i_blocks fields.
416 E2fsck will now print "Illegal indirect block", "Illegal
417 double-indirect block", etc., instead of "Illegal block #-1" or
418 "Illegal block #-2", etc. This makes it easier for users to
419 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
421 Mke2fs now will obtain get device topology information from blkid and
422 use it to populate the superblock stride and stripe sizes. It will
423 also warn if the block device is misaligned
425 Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
428 Fix the libext2fs library code to round up the bitmap size to a 4-byte
429 boundary, to prevent spurious seg faults caused by the x86
430 architecture. This doesn't affect Linux systems, but was a major
431 problem on a number of *BSD systems. (Addresses Sourceforge Bug:
434 Fix resize2fs's minimum size required for a file system so it doesn't
435 fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
437 Dumpe2fs now prints summary information about the contents of the
440 Avoid printing scary error messages when e2fsck starts running
441 problems on low-memory systems, as it tends to panic and mislead the
442 user. (Addresses Debian Bug: #509529)
444 Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
445 modules files. (Address Red Hat Bug: #518572)
447 Fix tune2fs so it can add a journal when an extent-enabled file system
448 is mounted. (Addresses Launchpad bug: #416648)
450 Update Czech, Indonesian, Polish and Vietnamese translations (from the
451 Translation Project).
453 Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
455 Fixed various Debian packaging issues --- see debian/changelog for
456 details. (Addresses Debian Bugs: #540111)
461 The configure script supports the --with-cc, --with-ccopts, and
462 --with-ldopts options. Instead, the more standard use of CC=,
463 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
464 Also, --with-ld, which never worked, was also removed.
465 (Addresses Sourceforge Bug: #2843248)
467 The in-tree header files are only used if the in-tree uuid or blkid
468 libraries are used. Otherwise, use the system-provided uuid or blkid
469 header files if using the system-provided libraries.
471 Fix some build failures caused by --disable-* configure options.
473 Work around a bug in autoconf 2.64.
476 E2fsprogs 1.41.9 (August 22, 2009)
477 ==================================
479 Fix a bug in e2fsck routines for reallocating an inode table which
480 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
481 filesystem feature with a relatively rare (and specific) filesystem
482 corruption. This fix causes e2fsck to try to find space for a new
483 portion of the inode table in the containing flex_bg, and if that
484 fails, the new portion of the inode table will be allocated in any
485 free space available in the filesystem.
487 Make e2fsck less annoying by only asking for permission to relocate a
488 block group's inode table once, instead of for every overlapping
489 block. Similarly, only ask once to recompute the block group
490 checksums, instead of once for each corrupted block group's checksum.
492 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
493 not present, and it needs to fall back to using the FIBMAP ioctl.
495 Fix filefrag to correctly print the number of extents for zero-length
496 files. (Addresses Debian Bug: #540376)
498 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
499 to more easily debug the FIBMAP code.
501 Fixed filefrag for non-extent based files.
503 Add a new program, e2freefrag, which displays information about the
504 free space fragmentation in an ext2/3/4 filesystem.
506 Fix inode resizing via tune2fs -I so that it works correctly in the
507 face of non-empty bad blocks inodes, and if the filesystem was
508 formatted using the "mke2fs -E stride=N" option for RAID arrays.
510 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
511 and corrupt large directories if the directory needs to shrink by more
512 than one block. (Addresses Debian Bug: #537510)
514 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
515 last mount times are in the future, they are corrected even if
516 buggy_init_scripts is set. This is needed because otherwise resize2fs
517 will refuse to resize the filesystem, even after running "e2fsck -f".
518 (Addresses Launchpad bug: #373409)
520 E2fsck will now print much fuller information when the last mount time
521 or last written time is in the future, since most people can't seem to
522 believe their distribution has buggy init scripts, or they have a
523 failed CMOS/RTS clock battery.
525 Enhance dumpe2fs to dump the extent information via the 'stat'
526 command, and more detailed extent information via the new command
529 Update French, Polish, Czech, and Sweedish translation from the
532 Fixed various Debian packaging issues --- see debian/changelog for
538 Fixed miscellaneous gcc -Wall warnings.
540 Fixed memory leak in error path in ext2fs_block_iterate2()
542 Fixed non-Linux build of the intl directory by adding support for the
545 The bitmap read/write functions now treat uninitialized bitmaps as
546 unallocated; this fixes a number of problems in all e2fsprogs for ext4
547 filesystems when there is a need to allocate new blocks or inodes, and
548 there aren't any free blocks or inodes in the already-used block
551 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
552 get inserted into the extent tree when they are not needed.
555 E2fsprogs 1.41.8 (July 11, 2009)
556 ================================
558 Fix resize2fs's online resizing, fixing a regression which in
559 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
561 Fix potential filesystem corruptions caused by using resize2fs to
562 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
565 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
566 setgid and the currently running program doesn't have write access to
567 the uuidd work directory.
569 Add safety checks (for non-Linux systems) so that uuidd isn't run with
570 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
571 will be careful not to close the file descriptor for its unix domain
572 socket when it detaches itself from the controlling tty. Also add
573 safety checks so that if the unix domain socket between the uuid
574 library and uuidd program is closed for any reason, both the library

600 optimized ext2fs_test_block_bitmap_range(), which will be needed for
601 future optimizations for e2fsck.
603 Fix makefile dependencies for libcom_err so that the Makefiles work
604 well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
606 Enhance the build system so that the full set of commands executed by

613 E2fsprogs 1.41.7 (June 29, 2009)
614 ================================
616 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
617 uninitalized data into the portion of the inode beyond the first 128
618 bytes when operating on inodes mapped via extents; potentially
619 corrupting filesystems.

625 The logsave program will now filter out the ^A and ^B characters when
626 writing to the console.

640 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
641 filesystems as the kernel when encoding rec_len >= 64k. For 64k
642 filesystems (currently all that is supported by e2fsprogs, this is
643 only a minor corner case).
645 Resize2fs will now update the journal backup fileds in the sup0erblock
646 if the journal is moved; this avoids an unnecessary full fsck after

669 valgrind with the appropriate options to find memory leaks.
672 E2fsprogs 1.41.6 (May 30, 2009)
673 ===============================
675 Fix a critical regression in e2fsck introduced version 1.41.5 which
676 can undo updates to the block group descriptors after a journal replay.
678 If e2fsck receives an I/O error while replaying the journal, prompt
679 the user whether they want to ignore the error or not; if e2fsck is
680 run in preen mode, force fsck to abort the preen pass.
682 Fix a bug which would cause e2fsck to core dump if the filesystem
683 contains a corrupt extent header, and the user declines to clear the
684 inode. (Addresses Sourceforge Bug: #2791794)
686 Fix e2fsck to restart only once in the case of multiple block groups
687 which inodes in use that are in the uninitialized part of the block
690 To reduce user confusion, if the /etc/mtab file is missing
691 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
692 new, explicit error code to indicate this case. This will cause
693 e2fsck to give a clearer error message when the user is using buggy
694 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
697 Fix e2fsck so that if the primary group descriptors are corrupted, but
698 the backup superblock is entirely invalid, to go back to using (and
699 fixing) the priary group descriptors instead of completely giving up
700 on the filesystem. (Addresses Debian Bug: #516820)
702 Change e2fsck to not abort a preen pass if an inode is found to have
703 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
704 kernels (post 2.6.29) will ignore this field. So let's fix it
705 automatically during the preen pass instead of forcing the user to fix
706 this up manually. (Addresses Debian Bug: #526524)
708 Add resource tracking for e2fsck passes 1b through 1d.
710 Speed up e2fsck by eliminating unnecessary journal checks if the
711 filesystem is already mounted and doesn't need recovery (since the
712 kernel would have run the journal when the filesystem was mounted.)
713 Also speed up e2fsck by avoiding unnecessary block group descriptor
714 updates in ext2fs_close().
716 Add support to chattr to migrate inodes from using direct/indirect
719 Avoid corrupting the filesystem if there is an attempt to shrink a
720 filesystem using resize2fs smaller than posible by making
721 ext2fs_set_bmap() more careful not to delete the old block until the
722 new block can be inserted. In addition, fix a bug in how the minimum
723 size of the filesystem (plus a safety margin) is calculated, and
724 modify resize2fs to refuse to shrink the filesystem below that minimum
725 size without the force flag.
727 Teach blkid to try to figure out DM device names using take advantage
728 of information in sysfs when running on kernels (2.6.29 and later)
729 which provide this information in /sys/block/dm-<N>/dm/name; this is
730 much faster than scanning for the devncie number in /dev/mapper.
732 Fix blkid to prefer /dev/mapper/<name> device names instad of the
733 private /dev/dm-X names.
735 Add an -a option to debugfs's close_filesys command which writes any
736 changes to the superblock or block group descriptors to all of the
737 backup superblock locations.
739 Add support to the filefrag program to use the FIEMAP ioctl.
741 Update Chinese translation from the Translation Project.
743 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
744 Launchpad Bug: #381854)
746 Fixed various Debian packaging issues --- see debian/changelog for
747 details. (Addresses Debian Bug #506064)
753 Add test code to make sure e2fsck's problem.c doesn't have two problem
754 codes assigned to duplicate values.
756 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
757 (Addresses Sourceforge Bug: #2780205)
759 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
760 function declaration for init_resource_track() and
761 print_resource_track() when RESOURCE_TRACK is not defined.
763 The test code which is used to build the tst_csum progam has been
764 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
765 avoid compile problems caused by not having a prototype for
766 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
768 Update the config.guess and config.sub file to the latest from the
769 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
772 Add a new function, ext2fs_extent_open2(), which behaves like
773 pext2fs_extent_open(), but uses the user-supplied inode structure
774 when opening an extent instead of reading the inode from disk.
777 E2fsprogs 1.41.5 (April 23, 2009)
778 =================================
780 Fix a number of filesystem corruption bugs in resize2fs when growing
781 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
784 Debugfs can now set i_file_acl_high via the set_inodes_field command,
785 and print a 64-bit file acl. This is useful for debugging filesystem
786 corruptions where the high bits of i_file_acl_high are set. E2fsck
787 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
788 since some Linux kernel versions pay attention to this field even when
791 Speed up e2fsck when checking clean filesystems by avoiding
792 unnecessary block reads, and coalescing the block group descriptor
793 blocks so they are read using a single read operation.
795 The libuuid library will now close all file descriptors before running
796 uuidd. This avoids problems when the calling program has open sockets
797 which then never get closed because uuidd is a long-running helper
798 daeomn. (Addresses Launchpad bug: #305057)
800 In order to avoid unnecessary full filesystem checks by e2fsck after
801 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
802 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
804 Mke2fs will avoid trying to create the journal when run in
805 superblock-only mode (mke2fs -S), since the left-over journal in the
806 inode table will cause mke2fs to fail.
808 Fix a bug in libext2fs functions that check to see if a particular
809 device or filesystem image is mounted, which would cause these
810 functions to report that a file identical to the (relative) pathname
811 used by a pseudo-filesystem was mounted when in fact it was not.
813 Update Czech translation from the Translation Project.
815 Add Chinese (simplified) translation from the Translation Project.
817 Fix support for external journals (which was broken in e2fsprogs
820 Fix a regression in debugfs where the "stat" command when no
821 filesystem was open would cause debugfs to crash with a segmentation
824 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
825 used to support filesystems without a journal. Update the blkid
826 library so it understands this.
828 The blkid library will remove an entry from the blkid cache
829 representing the entire disk if partitions are found, since presuambly
830 the device previously had no partition table, but has now transitioned
831 to using a partition table.
833 Add 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)
837 Add support for tracking the number kilobytes written to the
838 filesystem via the superblock field s_kbytes_written. It will be
839 updated by the kernel as well as by e2fsprogs programs which write to
840 the filesystem. This is useful for tracking the wear to filesystems
841 on Solid Sstate Drives.
843 Fix compatibility issue in the libext2fs info file and makeinfo
844 version 4.12. (Addresses Red Hat Bugzilla: #481620)
846 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)

857 Fix various gcc compilation warnings and other programming cleanups.

860 Add support for building the blkid command statically.
862 Add support for disabling the built-in blkid library in favor of a
863 system-installed blkid implementation via the configure option
867 E2fsprogs 1.41.4 (January 27, 2009)
868 ===================================
870 Fixed a bug which could sometimes cause blkid to return an exit value
871 of zero for a non-existent device (Addresses Debian Bug: #502541)
873 Blkid will now recognize ext3 filesystems that have the test_fs flag
874 set as ext3 filesystems.
876 The blkid library will now recognize btrfs filesystems and swap
877 devices currently used by user-level software suspend.
879 Tune2fs now updates the block group checksums when changing the UUID
880 to avoid causing e2fsck to complain vociferously at the next reboot.
882 Tune2fs's inode size resizing algorithms have been fixed so it is not
883 vastly inefficient for moderate-to-large filesystems, due to some
884 O(n**2) and O(n*m) algorithms that didn't scale well at all.
886 Fix tune2fs's inode resizing algorithm so it will not corrupt
887 filesystems laid out for RAID filesystems; in addition, tune2fs will
888 refuse to change the inode size for filesystems that have the flex_bg
889 feature enabled. (This is a limitation in the current implementation
892 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
893 filesystems with 32-bit block numbers, when the headers for 64-bit
894 block numbers was added. This regression has been fixed.
896 Debugfs's ncheck command has been fixed to avoid printing garbage
897 characters at the end of file names.
899 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
900 when shrinking filesystems with uninit_bg feature would not be moved.
901 In addition, blocks and inode table blocks were not being correctly
902 freed when shrinking filesystems with the flex_bg feable, which caused
903 resize2fs -M to fail. Finally, when blocks are moved, make sure the
904 uninitialized flag in extents is preserved.
906 Fix bug which caused dumpe2fs to abort with an error if run on a
907 filesystem that contained an external journal.
909 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
910 for this in argv[0] to provide better legacy support for these
911 distributions. This is a practice that should NOT be continued,
914 Mke2fs now has a new option -U, which allows the user to specify the
915 UUID that should be used for the new filesystem.
917 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
918 minus one block. This allows users who have read that ext3 supports
919 up to 16TB filesystems and who create a 16TB LVM to not get confused,
920 since the true limit is really 16TB minus one block.
922 E2fsck will no longer abort an fsck run if block group has an errant
925 E2fsck now distinguishes between fragmented directories and fragmented
926 files in verbose mode statistics and in the fragcheck report.
928 Fix a bug in e2fsck which casued it double count non-contiguous
931 E2fsck will leave some slack space when repacking directories to allow
932 room for a few directory entries to be added without causing leaf
933 nodes to be split right away.
935 Fix a bug which caused e2fsck to crash when it comes across a
936 corrupted interior node in an extent tree with the error message:
937 "Error1: Corrupt extent header on inode XXXXXX"
939 E2fsck problem descriptions involving the journal are no longer
940 referred to as "ext3" problems, since ext4 filesystems also have
943 Fix a long-standing bug in e2fsck which would cause it to crash when
944 replying journals for filesystems with block sizes greater than 8k.
946 Update Catalan translation from the Translation Project.
948 Fixed various Debian packaging issues --- see debian/changelog for
949 details. (Addresses Debian Bugs: #503057, #502323, #511207)
954 Fix build of e2fsck.profiled, and add support for building profiled
955 binaries in the misc directory if configured with --enable-profile.
957 The ext2fs_open() function now performs more sanity checks on the
958 superblock to avoid potential divide by zero errors by other parts of
961 The ext2fs_read_inode_full() function now has a safety check to avoid
962 a segmentation fault on corrupted filesystems.
964 The ext2fs_new_inode() function now has a sanity check so that if the
965 s_first_inode field in the superblock is insane, it will return
966 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
968 To avoid segmentation faults, ext2fs_block_alloc_stats() and
969 ext2fs_inode_alloc_stats() now validates the passed inode or block
970 number to avoid overrunning an array boundary.
972 Various signed/unsigned errors for variables containing block numbers
975 Accomodations for gcc's stupidity in not realizing that constant
976 strings that do not contain a '%' character are safe to use in format
977 strings have been made so that distributions that want to compile
978 e2fsprogs with -Werror=format-security have an easier time doing so.
980 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
982 Added the utility make-sparse.c to the contrib directory.
984 The ext2fs_block_iterate2() function now reflects errors from
985 ext2fs_extent_set_bmap() to the caller, if the callback tries to
986 change a block on an extent-based file, and ext2fs_extent_set_bmap()
987 fails for some reason (for example, there isn't enough disk space to
988 split a node and expand the extent tree.
990 The ext2fs_block_iterate2() function will preserve the uninit flag in
991 extents when the callback function modifies a block in an extent-based
994 E2fsck will now flag filesystems that have an insane s_first_ino field
995 in their superblock, and attempt to use a backup superblock to repair

1000 ===================================
1002 E2fsck has been fixed so it prints the correct inode number for
1003 uinit_bg related problems.
1005 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1006 is available on linux. This can be disabled via a configuration
1007 option in /etc/e2fsck.conf.
1009 Fix a file descriptor leak in libblkid when checking to see if an ext4
1010 or ext4dev module exists.
1012 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1013 while trying to close a filesystem can lead to infinite loops.
1014 (Addresses Red Hat Bugzilla #465679)
1016 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1017 will cause resize2fs to drop into an infinite loop. (Addresses Red
1018 Hat Bugzilla: #465984)
1020 Add a check in the Unix I/O functions in libext2fs so that when a
1021 device is opened read/write, return an error if the device is
1022 read-only using the BLKROGET ioctl.
1024 Fix debugfs's ncheck command so that it prints all of the names of
1025 hardlinks in the same directory.
1027 Fix a bug in libblkid so it correctly detects whether the ext4 and
1028 ext4dev filesystems are available, so that the ext4dev->ext4
1029 fallback code works correctly.
1034 Fix a parallel build problem by making sure util/subst is built before
1035 trying to build the lib/et directory. (Addresses Sourceforge Bug:
1038 Updated "make depend" information for crc16.o
1041 E2fsprogs 1.41.2 (October 2, 2008)
1042 ==================================
1044 Fix e2fsck's automatic blocksize detection. This fixes a regression
1045 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1046 specifies a block number using the -b option if the blocksize option
1047 isn't also specified using -B. Unfortunately, users very commonly
1048 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1049 superblock; in fack e2fsck will often suggest this kind of command
1052 Enhance the debugfs's "ncheck" command so it will print all of the
1053 pathnames for the specified inodes. (Previously, in some cases ncheck
1054 might not print a pathname for an inode at all if some of the other
1055 inodes had multiple hard links.)
1057 Enhance debugfs's "hash" command so the hash seed can be specified via
1058 a command-line option. In addition, allow the hash algorithm to be
1059 specified by name instead of just by number.
1061 Fix e2fsck so that we don't accidentally print the translation file's
1062 header when asking the user a custom question so there is no prompt
1063 defined for a particular problem record. For example, the question
1064 "Run journal anyway" will get the PO header tacked on because e2fsck
1065 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1103 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
1104 has been carrying a patch for a long time to prevent a largely
1105 theoretical race condition if a multi-threaded application adds and
1106 removes error tables in multiple threads. Unfortunately SuSE's
1107 approach breaks compatibility by forcing applications to link and

1146 E2fsprogs 1.41.1 (September 1, 2008)
1147 ====================================
1149 Many people are forgetting to update their mke2fs.conf file, and this
1150 causes ext3, ext4, and ext4dev filesystems won't get created with the
1151 proper features enabled. We address this in two ways. First, mke2fs
1152 will issue a warning if there is not definition for an ext3, ext4, or
1153 ext4dev filesystem and the user is trying to create such a filesystem
1154 type. Secondly, when installing from a source build, "make install"
1155 will provide basic configuration file handling for /etc/mke2fs.conf.
1156 If 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
1158 be installed. If the existing /etc/mke2fs.conf file does mention
1159 ext4dev, then "make install" will install official mke2fs.conf file as
1160 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1161 they should look to see if any changes need to be merged.
1163 The mke2fs program will now create the journal in the middle of the
1164 filesystem, since this minimizes seek times on average for fsync-heavy
1165 workloads. In addition, mke2fs will now create journals using extents
1166 for filesystems that support them. This results in a more efficient
1167 encoding for the journal since it eliminates the need for using
1170 The mke2fs program will avoid allocating an extra block to the
1171 journal. (Addresses Sourceforge Bug: #1483791)
1173 Mke2fs will correctly enforce the prohibition against features
1174 (specifically read-only features) in revision 0 filesystems. (Thanks
1175 to Benno Schulenberg for noticing this problem.)
1177 Mke2fs previously would occasionaly create some slightly non-optimally
1178 placed inode tables; this bug has been fixed.
1180 The mke2fs and tune2fs programs now print the correct usage message
1181 describing the maximum journal size. (Addresses Debian Bug: #491620)
1183 Add support for setting the default hash algorithm used in b-tree
1184 directories in tune2fs (from a command-line option) or mke2fs (via
1185 mke2fs.conf). In addition, change the default hash algorithm to
1186 half_md4, since it is faster and better.
1188 The blkid library will now recognize MacOS hfsx filesystems, and
1189 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1190 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1192 The blkid library has improved detection of JFS and HPFS filesystems.
1193 (Addresses Launchpad Bug: #255255)
1195 The blkid library is now much more efficiently handling devicemapper
1196 devices, mainly by no longer using the devicemapper library. This can
1197 speed up access for systems with a large number of device mapper
1200 Blkid had a number of cache validation bugs in libblkid that have been
1201 fixed. (Addresses Debian Bug: #493216)
1203 Resize2fs will now properly close out the "updating inode references"
1204 progress bar so there is a newline printed before printing the final
1205 "resize is successful" message.
1207 Resize2fs will now correctly handle filesystems with extents and/o
1208 uninitialized block groups correctly when file/directory blocks need
1209 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1210 is not present). To support this, the ext2fs library now supports
1211 initializing inode and block bitmaps that are not yet initialized when
1212 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1213 addition, e2fs_block_iterate2() can now support changing the location
1214 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1215 been optimized to avoid creating unnecessary new extents when updating
1216 the location of blocks in the extent tree. This will also help out
1217 e2fsck's recovery of obscurely corrupted filesystems with extents,
1218 when blocks are claimed by multiple inodes.
1220 Add support for on-line resizing ext4 filesystem with the flex_bg
1221 filesystem feature. The method for doing so is not optimal, but to do
1222 a better job will require kernel support.
1224 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1225 debugfs programs to not be able to read e2image files; the signed
1226 vs. unsigned bug in the code which read bitmaps from the e2image has
1227 been fixed. (Addresses Debian Bug: #495830)
1229 Resize2fs is now correctly managing the directory in-use counts when
1230 shrinking filesystems and directory inodes needed to be moved from one
1231 block group to another. This bug has been around since e2fsprogs
1232 1.26, and is largely harmless, but does cause a filesystem corruption
1233 which will be flagged by e2fsck after the filesystem has been shrunk.
1235 E2fsck will no longer issue spurious complaints about the inode size
1236 caused by very large extent-based files, and by blocks reallocated
1237 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1238 Kernel Bugzilla: #11341)
1240 Mke2fs will now set the creation timestamp on the lost+found directory
1241 and the root directory. (More generally, all new inodes created using
1242 the ext2fs library will correctly set the creation timestamp.)
1244 E2fsck now correctly calculates ind/dind/tind statistics in the
1245 presence of extent-based files. In addition, "e2fsck -v" will report
1246 statistics of the depth of extent trees in the filesystem. E2fsck can
1247 also give an inode fragmentation report using "e2fsck -E fragcheck"
1248 which can be useful when debugging the kernel block allocation
1251 Fix support for empty directory blocks in ext4 filesystems with 64k
1252 blocksize filesystems.
1254 E2fsck will now print the depth of corrupt htree directories.
1256 Debugfs's htree command now correctly understands extent-based
1257 directories. It will also print out the minor hash as well as the
1260 Debugfs has a new command which will print the supported features of
1261 e2fsprogs, to enable scripts to know whether the installed version of
1262 e2fsprogs can support a specific feature.
1264 Debugfs will now write files using extents for filesystems that
1267 The error message printed by "tune2fs -I" if the inode size was too
1268 small was rather confusing, so it has been improved. Also, we won't
1269 try to create an undo log until we know that command-line-specified
1270 parameters such as "tune2fs -I <inode size>" are valid.
1272 Given some filesystems found "in the wild" that had non-zero block
1273 group checksums even though the uninit_bg/gdt_sum feature was not
1274 enabled, e2fsck would issue spurious error messages. Teach
1275 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1276 entirely if the feature flag is not set. (Addresses Debian Bug:
1279 The blkid program will now print out a user-friendly listing of all of
1280 the block devices in the system and what they contain when given the
1281 -L option. (Addresses Debian Bug: #490527)
1283 The filefrag program now has a more accurate calculation for the
1284 number of ideal extents. (Addresses Debian Bug: #458306)
1286 The test I/O manager is now enabled by default, but its overhead is
1287 only incurred when it would be enabled via the TEST_IO_FLAGS or
1288 TEST_IO_BLOCK environment variables.
1290 Typographical errors in various program strings and usage messages
1291 have been fixed; most of these were pointed out by the e2fsprogs
1292 message catalog translators. (Thanks, translators!)
1294 Update and clarified various man pages, as well as some typographical
1295 errors in the libext2fs texinfo file.

1310 The "make check" target in the e2fsck directory now sets
1311 LD_LIBRARY_PATH before running the various e2fsck internal library
1314 The crc32 regression test in the e2fsck library is now portable to
1315 greater varienty of environments, including big-endian systems and

1317 Sourceforge Bug: #2019287)
1319 The ext2fs_extent_set_bmap() had some bugs when setting the first
1320 block in a file, or when replacing a single block extent. Those cases
1321 fortunately were came up relatively rarely when e2fsck was checking
1322 files, but caused some problems when resize2fs was shrinking
1325 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
1328 Various ext2fs library functions --- ext2fs_block_iterate2(),
1329 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
1330 allocated memory to avoid memory leaks in all of their error return
1333 Ext2ed was failing to build because masix support had been removed in
1334 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
1336 The configure script now respects the LDFLAGS environment variable if
1337 it is set when configure is called. (Addresses Sourceforge Feature
1340 Libuuid is now more portable to the Windows platform. (Addresses
1341 Sourceforge Feature Request: #1937287)
1343 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1344 bare echo commands so that configure flags such as --quiet work
1345 correctly. (Addresses Sourceforge Patches: #2058794)
1347 A few uses of sprintf have been removed from the ext2fs library to
1348 make life easier for bootloaders with a limited libc environment.
1349 (Addresses Sourceforge Bug: #2049120)
1351 The ext2fs_read_inode() checks the validity of the inode number passed

1356 passed to it earlier, to avoid doing some needless work when it would
1359 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1360 top-level Makefile. That automatic rule is used to better support
1361 SCCS, but it caused problems for a particular niche distribution which
1362 likes to use configure.sh files to store the configure options used to
1363 build a package. Unfortuntaely GNU make will use the configure.sh to
1364 replace the configure script, resulting in a self-inflicted fork bomb
1365 leading to an out-of-memory crash.
1367 To support old GNU C compilers don't use C99/C++ comments, but only
1368 K&R style comments, and don't try to use __builtin_expect if __GNUC__
1369 is less than 3. (__builtin_expect is only supported for gcc versions
1370 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1371 this is an optimization, we only try to use __builtin_expect for gcc 3
1374 In 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
1376 hence isn't portable.
1378 For the convenience for some distributions that need a static tune2fs,
1379 the Makefile for misc/ now has a tune2fs.static target.
1381 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1382 for extent-based files
1384 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1387 All source files no longer have any trailing white space.
1389 The io_channel_read_blk64() and io_channel_write_blk64() functions are
1390 now functions instead of C preprocessor macros to provide better
1391 forward compatibility.

1398 Fix a parallel build problem in e2fsprogs.
1400 E2fsprogs is now more portable to Solaris.
1401 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
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
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 $().
1420 The "make rpm" command will now take some extra configure optiosn from
1421 the build environment without needing to patch the source tree.
1423 The ext2fs_add_dir_block() function will now grow the dblist more
1424 aggressively as an optimization to avoid copying the array too often.
1426 The e2fsck_write_bitmaps() will write the block and inode bitmaps
1427 together instead of in two passes.
1430 E2fsprogs 1.41 (July 10, 2008)
1431 ==============================
1433 Add support for ext4 filesystem features, in particular extents,
1434 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
1435 support for checking journal checksums. Debugfs will print new
1436 superblock and inode fields that were defined for ext4. For example,
1437 the nanosecond and i_version fields of an inode, and the
1438 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1439 Note: Resize2fs doesn't currently support the combination of flex_bg
1440 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
1442 Tune2fs can support migrating a filesystem from using 128 byte inodes
1443 to 256 byte inodes, so it can take advantage of the full features of
1446 Add support for "undo" support. E2fsck and mke2fs can optionally
1447 record an undo log which can replayed by the program e2undo.
1449 E2fsck could damage a filesystem by trying to relocate inode tables
1450 due to corrupted block group descriptors, where the attempted inode
1451 table relocation would do far more harm than good. E2fsck has been
1452 fixed to detect this these sorts of corrupted block group descriptors
1453 much earlier in e2fsck processing, so it can try to use the backup
1454 superblock and block group descriptors first. This should be a much
1455 better strategy for recovering these types of corrupted filesystems.
1456 (Addresses Sourceforge Bug: #1840291)
1458 E2fsck will display a more understandable message when the last check
1459 field in the superblock is in the future. (Addresses Debian Bug:
1462 E2fsck now performs more extensive and careful checks of extended
1463 attributes stored in the inode.
1465 Enhance mke2fs to print a more explanatory error message when
1466 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
1469 Fix mke2fs to use a default block size of 4k when formatting an
1470 external journal device. This is done by using a fixed filesystem
1471 type list that consists only of the single filesystem type "journal"
1472 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
1473 Debian Bug: #488663)
1475 Speed up how mke2fs writes the journal data blocks by writing the disk
1476 blocks in larger chunks.
1478 Fix blkid handling of stale devices. Fix a bug which could cause a
1479 core dump while garbage collecting the blkid cache, and assure that
1480 blkid_find_dev_with_tag() never returns a non-existent device. Also,
1481 if a filesystem is found at a new /dev location, eliminate any
1482 duplicate stale entries which can not be verified.
1483 (Addresses Debian Bugs: #487758, #487783)
1485 Add more paranoid checks for LVM volumes and swap partitions in
1486 blkid's probe function, to reduce the chances of false positives.
1488 The mke2fs program now has a much more sophisticated system for
1489 controlling configuration parameters of a newly created filesystem
1490 based on a split filesystem and usage type system. The -t option to
1491 mke2fs was a deprecated alias to -c; it now specifies a filesystem
1492 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1493 separated usage list. The filesystem type information and type
1494 information is used to extract configuration parameters from the
1495 /etc/mke2fs.conf file.
1497 The mke2fs program will no longer complain and request the -f option
1498 when the user tries to create a filesystem with greater than 2**31
1501 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1502 adjust the mke2fs.conf file so filesystems for the Hurd are created
1503 with a blocksize of 4096 and inode size of 128, which is all it knows
1504 how to handle. (Addresses Debian Bug: #471977)
1506 Mke2fs will always make sure that lost+found always has at least 2
1507 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1509 Resize2fs will now print the minimum needed filesystem size if given
1510 the -P option, and will resize the filesystem to the smallest possible
1511 size if given the -M option.
1513 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1514 blocks are consumed during an off-line resize.
1516 The "ls" command in debugfs now supports the -p option, which causes
1517 it to quote the filenames so that spaces or tabs in directory entries
1518 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
1519 Sourceforge Feature Request: #1201667)
1521 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1524 The chattr program will return a non-zero exit code in case of
1525 failures, and error messages can be suppressed with the -f option.
1526 (Addresses Red Hat Bugzilla: #180596)
1528 Fix a bug in badblocks which caused it to overrun an array and likely
1529 crash if more than 8 test patterns are specified using the -t option.
1530 (Addresses Debian Bug: #487298)
1532 Add support to badblocks to limit how quickly it reads from the disk
1533 drive (so it can be used for background scrubbing), and so it will
1534 abort after finding a given number of errors.
1536 Remove support for the legacy big-endian filesystem format which only
1537 existed on extremely long-dead PowerPC kernels almost a decade ago.
1539 Remove MASIX support from e2fsprogs.
1541 Add I/O statistics reporting to e2fsck.
1543 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
1546 Fixed various Debian packaging issues --- see debian/changelog for
1547 details. (Addresses Debian Bugs: #487443, #487675, #490003)

1568 Clean up the badblocks group so to make it more portable and robust.
1570 Avoid using predictable filenames in /tmp in blkid's regression test
1571 suite. Also remove bashism's in the regression test script.
1573 If the configure script is given --with-diet-libc, don't use thread
1574 local storage, since diet libc doesn't support TLS. (Addresses
1575 Sourceforge Bug: #2000654)
1577 Fix the blkid regression test suite to tolerate older versions of
1578 mkswap that don't support the -U option.
1580 A few library routines have been converted to support 64-bit block
1581 numbers; in particular, the I/O manager functions, the test_io,
1582 inode_io, and unix_io managers have all be converted to support 64-bit
1585 Debugfs can now be extended for use by test programs. See
1586 lib/ext2fs/extents.c for an example for how it can be used. The test
1587 program links against the debugfs object files, and provides
1588 additional commands by defining an auxiliary libss command table.
1590 The lazy_bg filesystem feature, which was only used by developer's
1591 testing, has been removed since it has been largely supplanted by
1592 uninit_bg. This also simplifies the code.
1595 E2fsprogs 1.40.11 (June 17, 2008)
1596 =================================
1598 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
1599 percentage of reserved blocks. (Addresses Debian Bug: #452639)
1601 Updated Spanish and Catalan translations.
1603 Fixed various Debian packaging issues --- see debian/changelog for
1604 details. (Addresses Debian Bugs: #483962, #483023)
1606 Add detection for ZFS volumes to the libblkid library.
1608 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1609 (Addresses Debian Bug: #486463)
1614 Fix marginal C code in probe_lvm2() function to the blkid library more
1615 portable for older compilers.
1617 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
1619 Fix ext2fs_swap{16,32,64} functions so they can be used by external
1620 applications on big-endian machines. (Addresses Debian Bug: #484879)
1623 E2fsprogs 1.40.10 (May 21, 2008)
1624 ================================
1626 When deciding whether or not to revalidate a blkid cache entry, if the
1627 device's mtime is newer than the last time the cached entry was
1628 validated, force a revalidation.
1630 Fix a potential data corruption bug in e2fsck in the journal replay.
1631 The chances of this is happening is extremely remote, especially the
1632 default data=ordered or data=writeback modes. However, if a block
1633 which has been journalled starts with the first four bytes 0xc03b3998,
1634 when e2fsck replays the journal, those four bytes will be replaced
1635 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1636 metadata to begin with those fatal 4 byte sequence, and unless
1637 data=ordered mode is in use, data blocks are never journaled.
1639 Updated German, Dutch, Sweedish, and Vietnamese translations.
1644 Fixed various Debian packaging issues --- see debian/changelog for
1647 Remove default sizes of types when cross compiling, since autoconf
1648 2.50 can figure this out automatically now.
1651 E2fsprogs 1.40.9 (April 27, 2008)
1652 =================================
1654 SuSE's security team audited uuidd and came up with a few minor
1655 issues. None of them are serious given that uuidd runs setuid as a
1656 unprivileged user which has no special access other than libuuid
1657 directory, but it's good to get them fixed.
1659 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1660 work correctly with in-inode extended attributes.
1662 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
1665 Debugfs will avoid using a pager if the standard output is not a tty.
1667 Fix debugfs and tune2fs to correctly handle daylight savings time when
1668 parsing a time string.
1670 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1672 Fix fsck completion bars when multiple filesystems were being checked
1673 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
1674 #203323, Addresses Sourceforge Bug: #1926023)
1676 Fix fsck so that progress information is sent back correctly when
1677 multiple filesystems are being check and the output of fsck is being
1678 redirected to a file descriptor. Also, include the device name (w/o
1679 spaces) in the progress information sent back via a file descriptor.
1680 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
1683 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
1685 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
1686 signal to its child process.
1688 Fix mke2fs's creation of are resize inode when there is a non-standard
1689 s_first_data_block setting.
1691 Fix bug in blkid when run by an unprivileged user; most devices were
1692 not reported correctly. 9Addresses Launchpad Bug: #220275)
1694 Mke2fs will not allow the logically incorect combination of
1695 resize_inode and meta_bg, which had previously caused mke2fs to create
1696 a corrupt fileystem.

1718 (harmless) error message.
1721 E2fsprogs 1.40.8 (March 13, 2008)
1722 =================================
1724 Fixed e2image -I so it works on image files which are larger than 2GB.
1726 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1727 the size is larger than the number of blocks found in the inode, don't
1728 try to allocate extra empty blocks at the end of the directory to make
1729 up the difference; there's no point to doing that. In addition, if
1730 the size is not a multiple of a blocksize, always fix it.
1732 E2fsck handled a pass 2 "should never happen error" by not giving
1733 enough information and then core dumping. Unfortunately, it was all
1734 too easy to trigger the "should never happen" situation if a
1735 directory's inode size was not correct. This has been fixed, but
1736 e2fsck has also been taught how to handle this situation more
1737 gracefully, by simply removing the inode hash tree information, so
1738 that it can be rebuilt again after e2fsck's pass 3. (Addresses
1739 Launchpad Bug: #129395)
1741 Resize2fs had a bug resizing large inodes with extended attributes
1742 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1743 completely on big-endian systems such as PowerPC. The bug should be
1744 completely fixed now. Yay for regression test suites. (Addresses Red
1745 Hat Bugzilla: #434893)
1747 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
1748 translations. Many thanks to Philipp Thomas from Novell for stepping
1749 up to become the new German translation maintainer! (Addresses Debian
1750 Bugs: #302512, #370247, #401092, #412882).

1753 make it clear that it is just clearing the HTREE information, not the
1756 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1761 Add new functions, ext2fs_dblist_get_last() and
1762 ext2fs_dblist_drop_last(), which allows the caller to examine the last
1763 directory block entry added to the list, and to drop if it necessary.
1765 Fixed a portability problem in libblkid with DJGPP.
1767 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
1768 to Philipp Thomas for pointing this out.
1770 If the info files are not built, change "make install" so it doesn't
1771 fail with an error code.
1774 E2fsprogs 1.40.7 (February 28, 2008)
1775 ====================================
1777 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1778 depreciate the -s option, since it can result in filesystems which
1779 e2fsck can't fix easily. There are very good reasons for wanting to
1780 disable sparse_super; users who wants to turn off sparse_super can use
1781 debugfs. (Addresses Sourceforge Bug: #1840286)
1783 Add missing options to mke2fs's usage message. (Addresses Sourceforge
1786 Fix bug in resize2fs when large (greater than 128 byte) inodes are
1787 moved when a filesystem is shrunk; it was only moving the first 128
1788 bytes, so extended attributes were not getting moved. (Addresses Red
1789 Hat Bugzilla: #434893)
1791 E2fsck now prints an explicit message when the bad block inode is
1792 updated, to avoid confusion about why the filesystem was modified.
1793 (Addresses Sourceforge Bug: #756460)
1795 Allow mke2fs and tune2fs manipulate the large_file feature.
1796 Previously we just let the kernel and e2fsck do this automatically,
1797 but e2fsck will no longer automatically clear the large_file feature.
1798 It still isn't really necessary to worry about this feature flag
1799 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
1802 Suppress message about an old-style fstab if the fstab file is empty.
1803 (Addresses Debian Bug: #468176)
1805 Fix (really minor) bug in debugfs's find_free_block so it avoids
1806 reporting a free block more than once if there are too few free blocks
1807 in the filesystem. (Addresses Sourceforge Bug: #1096315)
1809 Change e2fsck to no longer clear the LARGE_FILES feature flag
1810 automatically, when there are no more > 2GB files in the filesystem.
1811 It's been almost a decade since there have been kernels that don't
1812 support this flag, and e2fsck clears it quietly without telling the
1813 user why the filesystem has been changed.
1815 Fix bug which could cause libblkid to seg fault if a device mapper
1816 volume disappears while it is being probed. (Addresses RedHat
1819 Inhance e2fsck's reporting of unsupported filesystem feature flags.
1820 (Addresses Sourceforge Feature Request: #1175808)
1822 Fix option syntax in dumpe2fs for explicit superblock and blocksize
1823 parameters. What was currently documented in the man page has been
1824 broken for some time, due to getopt() implementation changes. The
1825 option sytax has been changed to one which is can be more portable
1826 supported and which is consistent with the format for extended options
1827 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
1829 Add support to tune2fs to clear the resize_inode feature. This
1830 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
1832 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
1835 Add support for setting RAID stride and stripe-width via mke2fs and

1864 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
1865 partially filled-in filesystem object on an error, so that e2fsck can
1866 print more intelligent error messages.
1868 Add a new function e2p_edit_feature2() which allows the caller to
1869 specify which feature flags are OK to set or clear, and which returns

1936 Fix a potential overflow big in e2image if the device name is too
1939 Mke2fs will now create new filesystems with 256 byte inodes and the
1940 ext_attr feature flag by default. This allows for much better future
1941 compatibity with ext4 and speeds up extended attributes even on ext3
1944 Teach e2fsck to ignore certain "safe" filesystem features which are
1945 set automatically by the kernel. Having the kernel set features
1946 automagically behind the user's back is a bad idea, and we should try
1947 to break the kernel of this habit, especially for the newer ext4
1948 feature flags. But for now, we will try to avoid needless full checks
1949 which can annoy users who are doing fresh installs.
1951 Add support in tune2fs and mke2fs for making a filesystem as being "ok
1952 to be used with test kernel code". This will be needed for using test
1953 filesystems with the latest ext4 kernel code.
1955 Change e2fsck -fD so that it sorts non-htree directories by inode
1956 numbers instead of by name, since that optimizes performances much
1957 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
1959 If e2image fills the disk, fix it so it exits right away instead of
1960 spewing large numbers of error messages.

2037 Fix fsck to only treat the '#' character as a comment at the beginning
2038 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

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

2149 Add Catalan translation and update Dutch and Swedish translations
2150 from the Translation Project.
2152 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2153 still had an issue when trying to figure out whether we need to
2154 byte-swap fast symlinks that contained extended attributes.
2156 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2157 (Addresses SourceForge Bug #1821333.)
2163 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
2165 Add "make check" to the RPM spec file
2167 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2168 works correctly when the prefix is not the root directory.
2170 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2171 clena up after themselves by deleting the test.img temporary file
2172 after completing the test.
2174 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2175 first directory entry in a directory block and the last directory
2176 entry in the previous directory block is not in use. Fortunately
2177 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2178 places where it is extremely unlikely to run into this corner case.
2180 Fix missing dependency which would cuase parallel builds to fail.
2181 (Addresses Sourceforge Bug #1842331.)
2183 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2184 calling open(O_CREATE) with a missing mode parameter.
2186 Fix the test_ss.c in lib/ss so it can be used as an example
2187 application program for the library as well as a regression test
2190 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2191 are properly passed back up through the call stack.
2193 E2fsprogs 1.40.2 (July 12, 2007)
2194 ================================
2196 A recent change to e2fsck_add_dir_info() to use tdb files to check
2197 filesystems with a very large number of filesystems had a typo which
2198 caused us to resize the wrong data structure. This would cause a
2199 array overrun leading to malloc pointer corruptions and segfaults.
2200 Since we normally can very accurately predict how big the the dirinfo
2201 array needs to be, this bug only got triggered on very badly corrupted
2204 Fix a bug in e2fsck which caused it to incorrectly salvange
2205 directories when the last entry's rec_len is bogusly too big. This
2206 resulted in a nonsense filesystem corruption to be reported, and
2207 required a second run of e2fsck to fully fix up the directory.
2209 Update tune2fs man page to include more discussion of reserved blocks
2210 (Addresses Launchpad bug #47817)
2212 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2216 E2fsprogs 1.40.1 (July 7, 2007)
2217 ===============================
2219 Fix bug which could cause libblkid to loop forever. When revalidating
2220 a partition where there is obsolete information in /etc/blkid.tab, we
2221 end up freeing a the type tag without clearing dev->bid_type, causing
2222 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2224 The Turkish translation has a bug in it where it has the translation
2225 of "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
2227 dumps. We fix this by making e2fsck stop @-expansions after a
2228 recursive depth of 10, which is far more than we need.
2229 (Addresses Sourceforge Bug: #1646081)
2231 Compile the default mke2fs.conf into mke2fs program. People are
2232 getting surprised by mke2fs creating filesystems with different
2233 defaults than earlier versions of mke2fs if mke2fs.conf is not
2234 present. So we now create a built in version of mke2fs.conf file
2235 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2236 (Addresses SourceforgeBug: #1745818)
2238 Improve the config/parse_types.sh helper script. Fix a potential
2239 security problem if e2fsprogs is built as root (as Gentoo does!). In
2240 addition fix the script and how it is called from the configure script
2241 so that it does the right thing when cross-compiling. (Fixes Gentoo
2244 Update Vietnamese, French, and Dutch PO files from the Translation
2245 Project. Also created a new e2fsprogs.pot file for translator.
2247 Fix bogus strip permission errors when building under Debian. When
2248 building the e2fsprogs dpkg's, the dh_strip command emits a large
2249 number of error messages caused by the permissions not being right.
2250 So run dh_fixperms before running dh_strip.
2255 Add new function: profile_set_default(). This function sets the value
2256 of the pseudo file "<default>". If the file "<default>" had
2257 previously been passed to profile_init(), then def_string parameter
2258 will be parsed and used as the profile information for the "<default>"
2261 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2262 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2263 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2265 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2266 priority" environment variable that overrides all others, where as
2267 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2268 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2269 the all the rest are set. This will assure that the locale when
2270 running the test suites is the "C" locale. (Obviates Gentoo patch:

2277 Fix divide by zero error in blkid's NTFS probing logic.
2279 Add new blkid -g option which causes the blkid cache to be garbage
2282 Fix a bug in libblkid which could cause the internal field bid_type to
2283 become corrupted. Fortunately bid_type isn't used much, and bid_label
2284 and bid_uuid is only used by debugging code, so the impact of this bug

2288 created with a requested RAID stride, and then use it automatically in
2291 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2292 isn't too big. In some cases Lustre users have tried specifying an
2293 inode size of 4096 bytes, while keeping an inode ratio of one inode
2296 Improve sanity check in e2fsck's algorithm for finding a backup
2297 superblock, so that it won't accidentally find a superblock that was
2298 located in the journal, and then later reject it as being not a valid
2301 Fix e2fsck get_size logic so that it will work with the Linux floppy
2302 driver. The Linux floppy driver is a bit different from the other
2303 block device drivers, in that if the device has been opened with
2304 O_EXCL, it disallows another open(), even if the second open() does
2305 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2307 Fix error checking of badblock's last-block and start-block arguments.

2327 the backup journal information from the superblock was successfully
2328 used to recover the filesystem.
2330 Fix e2fsck so that it checks all of the blocks in the journal inode
2331 for validity. The original code only checked the direct blocks to
2332 make sure the journal inode was sane. Unfortunately, if some or all
2333 of the indirect or doubly indirect blocks were corrupted, this would

2351 Remove check in e2fsck which requires EA's in inodes to be sorted;
2352 they don't need to be sorted, and e2fsck was previously wrongly
2353 clearing unsorted EA's stored in the inode structure.
2355 Allow mke2fs or tune2fs to create a substantially larger journal (up
2356 to 10,240,000 blocks).
2358 Fix MD superblock detection, and make sure the correct UUID is
2359 reported from the MD superblock.
2361 Fix a signed vs. unsigned bug in debugfs.
2363 Enhance debugfs's date parser so that it accepts integer values.
2365 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
2366 file with multiply claimed blocks is hard linked. or not at all if the
2367 root directory contains shared blocks
2369 Enhance debugfs so it can modify the block group descriptors using the
2370 command set_block_group_descriptor.
2372 Improve e2fsck's reporting of I/O errors so it's clearer what it was
2373 trying to do when an error happens
2375 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
2376 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
2377 #232663 and LTC Bugzilla: #27634)

2390 Allow the debugfs lcd command to work w/o a filesystem being open.
2391 (Addresses LTC Bugzilla #27513)
2393 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
2394 field on the first pass.
2396 Fix e2fsck to set the file type of the '..' entry when connecting
2397 a directory to lost+found. (Addresses Lustre Bug: #11645)
2399 Enhance e2fsck to recover directories whose modes field were corrupted
2400 to look like special files. This is probably only useful in
2401 artificial test cases, but it will be useful if we ever do the "inodes
2402 in directory" idea for ext4.
2404 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
2407 Fix resize2fs parsing of size parameter (in sector units). This was
2408 actually a bug in libe2p's parse_num_blocks() function. When handling
2409 the 's' suffix, it was ignoring the blocksize information passed in
2410 from the caller and always interpreting the number in terms of a 1k
2411 blocksize. (Addresses Debian Bug: #408298)
2413 There was a floating point precision error which could cause e2fsck to
2414 loop forever on really big filesystems with a large inode count.
2415 (Addresses Debian Bug: #411838)
2417 Fix memory leak in ext2fs_write_new_inode()
2419 Add support for using a scratch files directory to reduce e2fsck's
2420 emory utilization on really big filesystems. This uses the TDB
2421 library. See the [scratch_files] section of the e2fsck.conf man page
2424 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
2425 platform (Addresses Debian Bug: #397044)
2427 Add explanatory message to badblocks that -n and -w are mutually exclusive
2428 (Addresses Debian Bug: #371869)
2430 Allow debugfs and dumpe2fs to support fs features under development.
2432 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2433 ext2fs_open() , which allows application to open filesystes with features
2434 which are currently only partially supported by e2fsprogs.
2436 Allow unix_io to support offsets greater than 2G (Addresses
2437 SourceForge Bug: #1547922)
2439 Fixed overflow and signed/unsigned problems caused by the number of
2440 blocks or inodes exceeding 2**31 or being close to 2**32-1.
2442 Add support for unsigned directory hash calculations with hints in the
2443 superblock to fix cross-architectural portability for htree
2444 directories with filenames where the high 8th bit is set. (Addresses
2447 Fix resize2fs so that it gives user-intelligible error messages if the
2448 filesystem or the kernel does not support on-line resizing.
2449 (Addresses Debian Bug: #380548)
2451 Require mke2fs -F -F for really dangerous operations, since -F is
2452 needed for less dangerous operations such as creating filesystems
2453 images in regular files, or creating filesystems on whole block
2454 devices. These relatively innocuous usages should NOT be confused
2455 with running mke2fs on an apparently-mounted or in-use filesystem.
2457 Allow the default inode size to be specified into the mke2fs.conf
2460 Make the smallest default journal size is big enough so that on-line
2461 resizing should always work.
2463 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
2466 Fix debugfs coredump when lsdel is run without an open filesystem
2467 (Addresses Debian Bug: #378335)
2469 Fix debugfs display bug us that bytes that have the high bit set are
2470 displayed as "ec" instead of "ffffffec".
2472 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
2474 Device mapper scanning wasn't working in the blkid library because the
2475 pathnames had an extra "/dev" when they were being probed.
2477 Add GFS/GFS2 support to the blkid library.
2479 Fix blkid support of empty FAT filesystem labels.
2481 Avoid recursing forever (or for a long time) when the blkid library
2482 searches for a device and there are symlinks to directories in /dev.
2484 Avoid unaligned halfword access in blkid when accessing FAT
2485 superblocks, as this will cause Sparc/Solaris systems to throw a
2488 The latest devmapper libraries requires pthreads, add -lpthreads to
2489 the static link libraries for e2fsck.static if devmapper is enabled.

2492 Improve the (non-installed, for experts only) findsuper program by
2493 printing the uuid and label from the superblocks, as well as the
2494 starting and ending offsets of the filesystem given the information in
2495 the superblock. Omit by default printing superblocks that are likely
2496 found in located in an ext3 journal unless an explicit -j option is
2499 Updated Spanish, French and Dutch translations and added Catalan
2500 translation. (Addresses Debian bug: #411562)
2502 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2503 determining a partition's size, since binary searching to determine
2504 the device doesn't work on FreeBSD.
2506 Documentation about UUID's is available in enough places, and it's
2507 awkward 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
2509 don't have do the dfsg tarball. Also remove the rule that only tried
2510 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2511 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
2513 Fix the info-dir line so that the menu name does not contain a .info
2514 prefix. First of all, it's ugly, secondly, it causes the install-info
2515 command 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
2517 purged. (Addresses Debian Bug: #401711)
2519 Fixed spelling mistakes, typos, and otherwise clarified man pages.

2530 E2fsck now supports the %It expansion when printing a problem report.
2531 It will print the type of the inode in the problem context.
2533 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
2534 (Addresses Sourceforge Bug: #1565561)
2536 Remove unused variables and other lint/gcc -Wall cleanups
2538 Add check to ext2fs_get_device_size() so it will return EFBIG for for
2539 filesystems contained in regular files where the filesystem image size
2540 is returned by stat64().
2542 Set local environment variables to C so mk_cmds and compile_et always
2543 work. (Addresses SourceForge Bug: #1532177)
2545 Added the 64-bit byte swapping function ext2fs_swab64().
2547 Added two new helper functions to prevent 2**31/2**32-1 overflow
2548 problems: ext2fs_div_ceil() and e2p_percent().
2550 Create new ext2fs library inline functions ext2fs_group_first_block()
2551 and ext2fs_group_last_block() in order to calculate the starting and
2552 ending blocks in a block group.
2554 Create the generated files read-only to remind developers not to edit them.
2556 Add support for autoconf 2.60 (with backwards compatibility for older
2557 versions of autoconf).
2559 Added an "make rpm" target to top-level Makefile
2561 Added various FreeBSD portability fixes.
2563 Exclude mercurial files from the RPM build tree to speed up copy/build.
2565 Use root_sysconfdir to define the locations of mke2fs.conf and
2566 e2fsck.conf instead of using a hard-coded /etc pathname.
2568 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2570 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2572 If diff -u is supported, use it to report test failures.
2574 Updates/improvements to RPM spec file
2576 Add on-disk format definitions for the following new features:
2577 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2578 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2579 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2581 Add a new make target "checked-failed" in the tests directory which
2582 reruns any failed tests
2584 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2586 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2587 pointer dereferences, memory leaks, etc. None were security-criticial
2590 Fix up usage and decrement error messages in the test_icount program
2592 Add debugging code to the com_err library; if the environment variable
2593 COMERR_DEBUG is set to 1, print out debugging messages as error tables
2594 are added and removed from the com_err library. If the
2595 COMERR_DEBUG_FILE environment variable is set (and the process is not
2596 setuid) the debugging messages may be redirected to a file.
2598 Change all of the e2fsprogs programs to use the newer add_error_table()
2599 and remove_error_table() interfaces instead of the much older
2600 initialize_*_error_table() function.
2602 Add TDB support into the ext2fs library. This allows us to have a
2603 guaranteed library we can count on always being present so we can
2604 store data in an on-disk database.
2606 Add support for using TDB to store the icount data, so we don't run out
2607 of memory when checking really large filesystems.
2609 Change the regression test suite so that it skips empty test directories.
2611 Define the l_i_iversion field in ext2_inode. The l_i_version field is
2612 now defined from the old l_i_reserved1 field in the ext2 inode. This
2613 field will be used to store high 32 bits of the 64-bit inode version
2616 Add Makefile production rule for e2fsprogs.spec in case it gets
2619 Add new function profile_get_uint() to allow for a clean way to fetch
2620 unsigned integers from the context.
2622 Add test to make sure the ext2 superblock structure is 1024 bytes.
2624 Fix typo in name of f_dup4 regression test
2626 Add new function blkid_gc_cache() which performs a garbage collection
2627 pass on the /etc/blkid.tab file.
2629 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2630 general, only e2fsck (after the filesystem is clean), tune2fs, and
2631 resize2fs should change the backup superblocks by default. Most
2632 callers of ext2fs_open() should not be touching any superblock fields
2633 which require the backups to be touched.
2635 Add new function to libext2fs, ext2fs_default_journal_size(), which
2636 returns the default journal size.
2639 E2fsprogs 1.39 (May 29, 2006)
2640 =============================
2642 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2643 between 2**31 and 2**32 blocks.
2645 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2646 configure the filesystem features, blocksize, and inode_ratio for
2647 different filesystem types.
2649 Mke2fs will now create filesystems hash trees and on-line resizing
2650 enabled by default, based on the new /etc/mke2fs.conf file.
2652 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2653 filesystem device node in exclusive mode to prevent accidents by
2654 system administrators. In the case of resize2fs and mke2fs, it will
2655 only use exclusive mode if the filesystem is not mounted.
2657 Fixed a bug in mke2fs which caused it to to fail when creating the
2658 resize inode for large filesystems. (Addresses Debian Bug #346580)
2660 When allocating space for the RAID filesystems with the stride
2661 parameter, mke2fs will now place each portion of the group's inode
2662 table right up after the superblock (if present) in order to minimize
2663 fragmentation of the freespace.
2665 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2666 efficiently by writing the inode and block bitmaps in one pass, thus
2667 reducing the number of disk seeks required.
2669 Add support for on-line resizing to resize2fs.
2671 Fix blkid library so that logic to determine whether or not a device's
2672 cached information in /etc/blkid.tab needs to be verified or not
2673 doesn't get confused by a system clock which is insane (for example,
2674 if the battery is dead on a Macintosh running PPC Linux. (Addresses
2675 Red Hat Bug: #182188)
2677 The blkid library will now store the UUID of the external journal used
2678 by ext3 filesystems, so that in the future, the userspace mount binary
2679 can use this to find the location of the external journal and pass
2680 this information to the kernel.
2682 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2683 control how various options should be handled. See the e2fsck.conf
2684 man page for more details. (Addresses Debian Bug: #150295)
2686 E2fsck now prints an explanatory message when delaying a filesystem
2687 check when the system is running on battery. (Addresses Debian Bug:
2690 E2fsck will detect if the superblock's last mount field or last write
2691 field is in the future, and offer to fix if so. (Addresses Debian Bug
2692 #327580) These problems will be fixed automatically in preen mode
2693 since Debian's boot sequence bogusly doesn't set the time correctly
2694 until potentially very late in the bootup process, and this can cause
2695 false positives which will cause users' systems to fail to boot.
2696 (Addresses Debian Bugs #343662 and #343645)
2698 E2fsck now checks to see if the superblock hint for the location of
2699 the external journal is incorrect, and if so, offer to update it.
2700 (Addresses Debian Bug: #355644)
2702 Fix e2fsck from segfaulting on disconnected inodes that contain one or
2703 more extended attributes. (Addresses Debian Bug: #316736, #318463)
2705 E2fsck will stop and print a warning if the user tries running a
2706 read/write badblocks test on a read-only mounted root filesystem.
2708 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2709 C. Thompson for pointing these out; they were originally found using
2712 When resizing a file containing a filesystem, resize2fs will expand or
2713 truncate a file as necessary. (Addresses Debian Bug: #271607)
2715 Resize2fs will now automatically determine the RAID stride parameter that
2716 had been used to create the filesystem, and use that for newly created
2717 block groups. The RAID stride parameter may also be manually specified
2718 on the command line using the new -S option to resize2fs.
2720 Fix mke2fs so that it correctly creates external journals on
2721 big-endian machines (such as a S/390).
2723 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2724 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2725 Chambraud for pointing this out.)
2727 Dumpe2fs will now print the size of the journal (if present).
2729 Fix debugfs's set_inode_field command so it can properly set the frag,
2730 fsize, uid_high, gid_high, and author fields in the inode instead of
2731 silently failing, and so that setting the i_size actually sets i_size
2734 Add a new debugfs command, set_current_time, which sets fs->now so
2735 that regression test suites can repeatedly modify the filesystem's
2738 Fix a bug in debugfs's icheck which would incorrectly report the owner
2739 of an extended attribute block.
2741 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2742 print a usage message when an illegal option character is given.
2744 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2745 so it won't core dump. (Addresses SourceForge bug #1424311)
2747 Fix mklost+found so that it creates a full-sized directory on
2748 filesystems with larger block sizes.
2750 Fix a file descriptor leak in blkid library.
2752 Fix a display bug in "badblocks -sv" so that the done message properly
2753 clears the block number at the end of the test. (Addresses Debian Bug
2756 Allow fractional percentages to the -m option in mke2fs and tune2fs

2759 Use fstat/fstat64 in getsize.c if the the target is a regular file,
2760 instead of attempting to do a binary search. Fix some fd leaks in

2764 that the "best" (i.e., leaf) device is probed by the blkid library.
2766 Fix the blkid library so that it notices when an ext2 filesystem is
2769 Improve the blkid's library VFAT/FAT detection; it now understands
2770 labels stored in the root directory, and is more paranoid about
2771 checking the FAT superblock values.
2773 Fixed a fd leak in the uuid library which was causing problems for the
2774 LVM tools. (Addresses Debian Bug: #345832)
2776 Add support for the reiser4 and software suspend partitions to the
2777 blkid library. Also add support for extract the label from iso9660
2780 Fix a compile_et bug which miscount the number of error messages if
2781 continuations are used in the .et file.
2783 Add extra sanity checks to protect users from unusual cirucmstances
2784 where /etc/mtab may not be sane, by checking to see if the device is
2785 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
2788 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
2789 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
2791 Fix use-after-free bug in e2fsck when finishing up the use of the
2792 e2fsck context structure.

2812 Bugs: #360661, #360317)
2814 Fixed the Makefile so that they work correctly on newer versions of
2815 GNU make (i.e., 3.81).
2817 Add valgrind support to the regression test suites, and eliminate
2818 false positives from valgrind.
2820 Add a regression test suite for the blkid library.
2822 Fix a fencepost error in resize2fs caught by valgrind.
2824 Fix compiler warnings about missing memcpy prototypes.
2826 We no longer have the sparc assembly code in the header file any more,
2827 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2828 break compiles on the sparc architectures when using gcc.
2830 In the libext2fs library, add the new field fs->now which if non-zero
2831 is used instead of the system time when setting various filesystem
2832 fields (last modified time, last write time, etc.)
2834 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2835 ext2fs.h which is needed since the inline functions use memcpy().
2836 (Addresses Sourceforge Bug #1251062)
2838 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2839 the build system when building files in the util directory which are
2840 needed during the build process. This avoids potential problems when
2841 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2842 are not recognized as valid by the host compiler. (Addresses
2843 Sourceforge Bug #1261547)
2845 Clean up the blkid library by making the superblock and generic i/o
2846 functions to be more generic. Clean up interface to the probe
2847 function, and fix memory leak. Finallly, remove an unneeded reference
2848 to probe.h in the lib/blkid/resolve.c
2850 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2851 of invalid block #'s.
2853 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2854 indicate that the the function read/writes the memory location.
2856 Fix various gcc -Wall complaints.
2858 Add a dependency to make sure that the subdirectories are created
2859 before creating all of the object files, in order to address parallel
2860 build problem in the library Makefiles. (Addresses Sourceforge Bug:
2863 Add $(LDFLAGS) to the command line argument when generating an ELF or
2864 Solaris shared library, to allow cross-compile and other builds that
2865 might need to specify -L paths to needed libraries. (Addresses
2866 Sourceforge Bug #1261549)
2868 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2869 intended for testing purposes. It allows an ext2/ext3 developer to
2870 create very large filesystems using sparse files where most of the
2871 block groups are not initialized and so do not require much disk
2872 space. Eventually it could be used as a way of speeding up mke2fs and
2873 e2fsck for large filesystem, but that would be best done by adding an
2874 RO_COMPAT extension to the filesystem to allow the inode table to be
2875 lazily initialized on a per-block basis, instead of being entirely
2876 initialized or entirely unused on a per-blockgroup basis.
2878 Fix backwards compatibility so e2fsprogs will better compile on Linux
2881 Make test scripts more robust against locale-related environment variables
2883 Fix type warning problem with sizeof() in ext2fs_open2().
2885 Fix type warning problem with time_t in debugfs.

2889 ==============================
2891 Fix blkid's test programs (built with "make check") compile correctly
2892 even without "configure --enable-blkid-debug".
2894 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2895 type aliasing rules on newer gcc compilers. (Addresses Red Hat
2898 Fix com_err library to make it more compatible with recent changes
2899 made to the com_err library in MIT Kerberos V5 version 1.4.
2900 (Addresses Sourcefroge Bug #1150146)
2902 General cleanup of messages printed by e2fsprogs programs for grammar,
2903 consistency, and to make life easier for translators. Fixed a few
2904 strings containing English that had not been marked as needing
2905 translations. Removed strings that do not need to be translated, to
2906 make life easier for translators.
2908 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2909 test to see if a device appears to be in use instead of just relying
2910 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
2912 Fix portability problem in the filefrag program affecting platforms
2913 where the size of an integer is smaller than the size of a long.
2914 (Addresses Debian Bug #309655)
2916 Mke2fs will now use a larger journal by default for filesystems
2917 greater than 4GB. (128 MB instead of 32MB).
2919 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2920 unless forced. This is to avoid signed vs. unsigned kernel bugs in
2921 block numbers that still need to be fixed.
2923 The blkid program has a new option which will more efficiently search
2924 for device when it is known (or expected) that only one matching
2925 device will be found in the system, such as when doing a lookup by
2928 Debian's e2fsprogs-specific initrd fragment will avoid including
2929 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2930 and LD_LIBRARY_PATH, and filtering out libraries found in
2931 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
2933 Fixed a potential portability issue in the blkid programs for
2934 architectures where the char type is unsigned. (Addresses Sourceforge
2937 Fix a bug in filefrag so that it doesn't falsely count an extra
2938 discontinuity when the first block found is an indirect block.
2939 (Addresses Debian Bug #307607).
2941 Fix blkid's recognition of cramfs filesystems, and enhance it to be
2942 able to handle cramfs labels.
2944 Fix debugfs's stat command to not core dump when a filesystem is not
2947 Fix e2fsck's handling of error conditions caused by the resize inode
2948 claiming blocks that are also used by other inodes, a filesystem
2949 corruption which was commonly caused by a bug in Fedora Core 3's
2952 Fixed bug in filefrag which caused it to fail on non-ext2/3
2953 filesystems. (Addresses Debian Bug: #303509)
2955 If the superblock last mount time indicates that the system clock may
2956 not be accurate, then e2fsck will omit checking inodes' deletion time
2957 field for indications of a potential corrupted orphaned inode list.
2958 (Previously e2fsck only ommited these LOW_DTIME checks when the
2959 superblock's last write time looked insane.)
2961 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
2962 (Addresses Debian bug #302200)
2964 Make the blkid library more paranoid about being run from setgid
2965 programs, and to use __secure_getenv() from libc if it is available.
2967 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2968 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
2969 and Sourceforge Bug: #1189803)
2971 Updated and fixed translations.
2973 Fixed various Debian packaging issues --- see debian/changelog for
2979 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2980 changed to take an unsigned int for the bit number. Negative bit
2981 numbers were never allowed (and didn't make any sense), so this should
2982 be a safe change. This is needed to allow safe use of block numbers
2983 greater than or equal to 2**31.
2985 The compile_et program will avoid recreating generated foo_err.c and
2986 foo_err.h files if no changes are necessary. The compile_et program
2987 will also atomically replace these files to avoid a potential parallel
2988 build race problem on SMP systems. (Addresses Sourceforge Bug:
2991 Added a new function to the blkid library, blkid_probe_all_new(),
2992 which only probes newly added disk devices, and change
2993 blkid_find_dev_with_tag() to use this function so that when a
2994 requested tag is not found, devices that were previously not checked
2995 are searched before searching all devices in the system.
2997 Added new functions to the blkid library, blkid_dev_set_search() and
2998 blkid_dev_has_tag().
3000 E2fsck's problem strings can now use @m and @n as abbrevations for
3001 "multiply-claimed" and "invalid", respectively.
3003 The e2fsprog.pot file now has an explanation of how the @-expansion
3004 and %-expansion works, and strings in e2fsck/problem.c which contain @
3005 characters now have comments in e2fsprogs.pot with the @-expansion to
3006 make life easier for translators.
3008 Fixed missing return values in the ext2fs library which could cause it
3009 to return random garbage in certain error conditions.
3011 Allow the current time to be overriden via the E2FSCK_TIME environment
3012 variable for use in regression tests.
3014 The test scrpit driver program now exits with a non-zero status if
3015 there any of its test that it ran failed.
3017 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
3020 Fixed "make check" so that it compiles correctly even when e2fsprogs'
3021 header files have not be installed in the system include directories.
3022 (Addresses Sourceforge Bug: #1180572)
3024 Fixed gcc -Wall nits.
3027 E2fsprogs 1.37 (March 21, 2005)
3028 ===============================
3030 Add support for checking the validity of Extended Attributes stored in
3033 Add support for dumping the contents of large inodes to debugfs,
3034 including the extended attributes stored in inodes.
3036 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3037 when we create a new inode we make sure that the extra information in
3038 the inode (any extra fields in a large inode and any ea-in-inode
3039 information) is initialized correctly. This can take place when
3040 mke2fs creates the root and lost+found directory, when e2fsck creates
3041 a new root inode or a new lost+found directory, and when the user uses
3042 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3043 create inode could inherit garbage (or old EA information) from a
3044 previously deleted inode.
3046 Fixed a bug in e2fsck so it would notice if a file with an extended
3047 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3050 Added support to filefrag to detect files which are using the new
3051 experimental file extents format, and use the non-ext2 algorithm in
3052 that case. Fixed a bug to avoid reporting a false discontinuity if
3053 there is one or more unallocated blocks at the beginning of a file.
3055 Duplicated a check for noticing whether or not the number of blocks
3056 (given a certain blocksize) is greater than 2**32 when the
3057 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3058 allows mke2fs to automatically use a larger blocksize when creating a
3059 filesystem on a very large device when run on systems that do not
3060 support BLKGETSIZE64.
3062 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3063 build system had been switched to treat the .gmo files as shipped
3064 files (for backwards compatibility with systems that have older GNU
3065 I18N tools installed), but the gen_tarball.in script was still
3066 removing the .gmo files from the official source distribution.
3068 Fixed various Debian packaging issues --- see debian/changelog for
3069 details. (Addresses Debian Bugs ##296769, #299341)
3074 Added new functions to the e2p library which convert between a string
3075 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3076 make the generated binaries more compact.
3078 Fixed a compile-time error on Darwin systems.
3080 Cleaned up the lib/ext2fs Makefile slightly.
3083 E2fsprogs 1.36 (February 4, 2005)
3084 =================================
3086 All of the patches that were applied to Fedore Core 3's
3087 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3088 lot of bug fixes first. Users of Fedora Core 3 are strongly
3089 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3091 Add support for filesystem with the online resizing via resize inode
3092 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3093 patches also didn't bother to do any consistency checking on the
3094 resize inode, or add any tests to the regression test suite. The "-R
3095 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3096 being listed in mke2fs's usage message. All of these shortcomings
3097 have been corrected.
3099 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3100 program. In order to do this, the user must run the commands:
3102 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3103 e2fsck -f /dev/hdXXX
3105 Optionally, the ext2prepare command can be used to re-enable online
3106 resizing after the filesystem has been fixed.
3108 The fsck program will now accept an optional filedescriptor argument
3109 to the -C option. (The Fedora version of this patch would sometimes
3110 cause fsck to ignore a parameter on fsck's command line in some rare
3113 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3116 Make sure resize2fs releases the blocks belonging to the old inode
3117 table blocks when moving the inode table. (Addresses Debian Bug:
3120 Skip the r_resize_inode test if resize2fs is not compiled (due to
3121 configure --disable-resizer)
3123 E2fsck now checks the summary filesystem accounting information, and
3124 if any of the information is obviously wrong, it will force a full
3125 filesystem check. (Addresses Debian Bug #291571)
3127 Fix e2fsck to not complain when the resize_inode feature is enabled,
3128 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3131 Fix e2fsck to note delete symlinks that contain an extended attribute
3132 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3135 Add new utility program, copy_sparse.c, which is very useful
3136 for dealing with large sparse files (such as e2image files).
3138 Add support for jnl_blocks[] for debugfs's set_super_value.
3140 Fix filefrag so that it works correctly with sparse files.
3142 Filefrag -v will print first and last blocks.
3144 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3147 Add mke2fs support so that it can support filesystems larger than 4TB
3148 automatically, by retrying with a 4k blocksize if the device size is
3149 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3152 Change blkid to test for NTFS first because Windows sometimes doesn't
3153 clear enough of the parition to confuse the probing routines into
3154 thinking the old filesystem type is still valid. (Addresses Debian
3157 Add support for swap partition label and uuid's in the blkid library.
3159 Add support to the blkid library to recognize Oracle ASM volumes.
3161 Make blkid -t display all devices that match the specified criteria,
3162 not just the first one, and work more consistently when the blkid
3163 cache file is not available or set to /dev/null. (Addresses Debian
3164 Bug #290530 and #292425)
3166 Badblocks will now correctly display block numbers greater than
3167 999,999,999 in its progress display.
3169 The tune2fs program will not allow the user from setting a ridiculous
3170 number of reserved blocks which would cause e2fsck to assume the
3171 superblock was corrupt. E2fsck's standards for what is a ridiculous
3172 number of reserved block has also been relaxed to 50% of the blocks in
3175 The blkid library will return vfat in preference to msdos, and ext3 in
3176 preference to ext2 (if the journalling flag is set) so that mount will
3177 do the right thing. (Addresses Debian bug #287455)
3179 Mke2fs will now use the -E option for extended options; the old -R
3180 (raid options) option is still accepted for backwards compatibility.
3181 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3183 Mke2fs 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
3185 convenient than specifying a block count.
3187 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3188 cache conherency problem.
3190 Debugfs now supports a new command, set_inode_field, which allows a
3191 user to manually set a specific inode field more conveniently, as well
3192 as set entries in the indirect block map.
3194 Debugfs's set_super_value command has been enhanced so that the user
3195 can set most superblock fields, including the date/time fields and
3196 some of the more newsly added superblock fields.
3198 E2fsprogs programs now accept an offset to be passed to the file
3199 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3201 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3202 support on the x86 doesn't exist for now, but it can be useful on
3203 other architectures with page sizes greater than 4k. There are 2.6
3204 kernel patches out there which enable this, but they are of this
3205 writing still experimental.
3207 The e2image command now takes the -s option which will scramble
3208 directory entries for raw image files.
3210 Fix a file descriptor leak in the filefrag program.
3212 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3215 Fix bug in debugfs where kill_file would lead to errors when deleting
3216 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3218 Fix bug in the blkid library when detecting the ocfs1 filesystem
3220 Remove obsolete EVMS 1.x and a.out DLL support.
3222 E2fsck will attempt to recover from a journal containing illegal blocks.
3224 Fixed two potential ordering constraint problems in e2fsck which might
3225 cause the filesystem to be corrupted if e2fsck is interrupted during a
3226 (extremely narrow) race window. Thanks to Junfeng Yang from the
3227 Stanford Metacompilation group for pointing this out.
3229 Fixed bug in e2fsck where it would not accurately detect whether or
3230 not the system is running on adaptor if the ACPI device representing
3231 the AC adapter didn't correspond to the what was used on IBM
3234 Change e2fsck to accept directories greater than 32MB.
3236 Fix e2fsck so that a checkinterval of zero disables a time-based check
3239 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3240 to the PAGER environment variable. (Addresses Debian Bug #239547)
3242 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3245 The debugfs program will set the filetype information when creating a
3248 Add debugfs -d option to use a separate source of data blocks when
3249 reading from an e2image file.
3251 Add e2image -I option which allows the e2image metadata to be
3252 installed into a filesystem.
3254 Fixed bug in the badblocks program which caused "done" to always
3255 appear in english even when a translation was available. (Addresses
3258 The blkid program has a new option -o which controls the output format
3259 of the blkid program; this is makes blkid more convenient to use in
3262 Fix a minor bug in uuid library, which was not using the full 14 bits
3263 of clock sequence when generating UUID's.
3265 Fix a Y8.8888K problem in the uuid library.
3267 Logsave now creates a new session id for itself to avoid getting
3268 killed by init whan transitioning between init levels.
3270 Change the licensing of the UUID library to be the 3-clause BSD-style
3271 license; this allows Apple to use the uuid library in Darwin.
3273 Add ocfs and ocfs2 probe support into the blkid library.
3275 Fix a memory and file descriptor leak in the blkid library.
3277 The blkid library will revalidate the device if the system time is
3278 earlier than last verification time of the device, since that
3279 indicates that the system time is probably nottrustworthy.
3281 The blkid library will override the default location of the blkid.tab
3282 file by the BLKID_FILE environment variable, if it is available.
3284 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3286 Add various portability fixes for lame new versions of glibc, Darwin
3287 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3288 Bugs #239934, #264630, #269044, #255589, #289133)
3290 Add support for Windows 9x/NT under Cygwin.
3292 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3293 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3295 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3297 Update the rpm spec files so that it works better with Fedora core 2
3300 Fixed various Debian packaging issues (see debian/changelog). In
3301 particular, fixed the Debian initrd scripts. (#241183, #248050,
3308 Fixed various gcc -Wall warnings.
3310 The uuid library now has new functions uuid_unparse_upper() and
3311 uuid_unparse_lower() which forces the case of the hex digits to be
3312 upper case, or lower case.
3314 The build process has been speeded up by enhancing the subst program
3315 to update the modtime on the generated files even when the generated
3316 file hasn't changed.
3318 The uuid library now uses C99 stdint.h types instead of custom types.
3320 Updated config.guess and config.sub with newer versions from the FSF.
3322 Removed out of date .cvsignore files from the source distribution.
3324 The ext2fs_unlink() function will return an error if both the name and
3325 inode number are unspecified, to avoid doing something surprising
3326 (such as unconditionally deleting the first directory entry).
3327 Directory entries are now deleted by coalescing them with the previous
3328 directory entry if possible, to avoid directory fragmentation. This
3329 is not an issue with the e2fsprogs suite, but may be a problem for
3330 some of the users of libext2fs, such as e2tools.
3332 Add support for version numbers of the form "1.36-rc1".
3334 Fix build of mke2fs.static.
3336 Add basic ext2fs library support for large (EA in inode) inodes.
3338 The test_io mechanism can now abort after n reads or writes to a
3339 particular block. The block is specified by TEST_IO_BLOCK environment
3340 variable, and the read/write count by the TEST_IO_READ_ABORT and
3341 TEST_IO_WRITE_ABORT environment variables. The block data is now only
3342 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3344 UUID_DEFINE() in the uuid library now creates a static variable, with
3345 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3346 be used in header files.
3348 Add support for the install-strip and install-shlibs-strip targets, as
3349 suggested by the GNU coding guielines. "make install" no longer
3350 strips the binaries which are installed.
3352 Remove support for the --enable-old-bitops configure option which was
3353 only for very old sparc systems.
3355 Remove support for --enable-clear-htree; this was only needed during
3356 the early development of the htree patch.
3358 Use Linux-kernel-style makefile output so it is easier to see compiler
3361 Update gettext files to version 0.14.1.
3363 Update to use autoconf 2.5x.
3365 Improved support for compiling e2fsprogs under dietlibc.
3367 Make e2fsprogs portable to Solaris and FreeBSD systems.
3369 Add blkid_verify(), blkid_get_library_version(), and
3370 blkid_parse_version_string() functions to the blkid library.
3372 Add pkg-config files for e2fsprogs's libraries.
3374 Fix "make uninstall" to so that it removes everything that is installed.
3376 Add a configure --enable-maintainer-mode option which enables the
3377 makefile rules to rebuild the configure script from configure.in, and
3378 to reubuild the .gmo files in po directory.
3380 Drop the sparc assembly bitwise operations; it's less efficient
3381 than the GCC 3.4 compile code and triggers compiler warnings on
3382 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

3386 E2fsprogs 1.35 (February 28, 2004)
3387 ==================================
3389 E2fsck has a new -k option, which in conjunction with the -c options,
3390 preserves the existing badblocks list.
3392 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3394 E2fsprogs will now deal correctly with symlinks that contain
3395 extended attribute information, which can be created using SE Linux.
3396 (Addresses Debian Bug #232328)
3398 Remove a double longjump into an invalid stack frame bug in e2fsck.
3399 (This was during an abort sequence, which normally worked on Linux and
3400 caused a core dump on other operating systems.)
3402 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3403 (the NLS library will replace "" with the .po header information).
3405 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3406 dump due to a division by zero error. (Addresses Debian bug #207082)
3408 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3409 when reconnecting a directory requires creating a lost+found
3410 directory. (Addresses Debian bug #219640).
3412 Fixed a bug where e2fsck would bomb out if a journal needed to be
3413 replayed when using an alternate superblock.
3415 E2fsck will give an extra grace period before actually forcing a check
3416 if the laptop is running on battery. The next time fsck runs while
3417 the system is on the AC mains, or after the grace period is exceeded,
3418 the filesystem will be checked. (Addresses Debian bug #205177)
3420 E2fsck will inform the user when there are 5 or fewer mounts before a
3421 filesystem check will be forced. (Addresses Debian bug #157194)
3423 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3424 We now correctly handle the case where there is an overlap between a
3425 block group descriptor or a superblock and a bad block indirect block.
3426 In the case where the indirect block is corrupted, we now suggest
3429 Fix byte swap bugs in e2fsck that caused the journal backup location
3430 in the superblock and symlinks created by SE Linux to be cleared
3431 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
3433 E2fsck -c now replaces the current list of bad blocks with the ones
3436 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3437 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3439 Fix a potential bug in e2fsck which could cause it to core dump when
3440 trying to print the location of the backup superblock.
3442 Protect against a potential core dump in e2fsck when printing a
3443 message about backup superblocks.
3445 Add support for backing up the journal inode location in the
3446 superblock. E2fsck will automatically save the journal information in
3447 the superblock if it is not there already, and will use it if the
3448 journal inode appears to be corrupted. ext2fs_add_journal_inode()
3449 will also save the backup information, so that new filesystems created
3450 by mke2fs and filesystems that have journals added via tune2fs will
3451 also have journal location written to the superblock as well.
3452 Debugfs's logdump command has been enhanced so that it can use the
3453 journal information in the superblock.
3455 E2fsck will now update all superblocks when moving the journal inode.
3457 Shrink the size of the e2fsck executable by moving some initialized
3458 variables to the BSS segment.
3460 E2fsck will avoid printing the ^A and ^B characters which bracket the
3461 progress bar when stdout and stdin are a tty device instead of a pipe
3462 to another program. (Addresses Debian bug #204137)
3464 Debugfs's mkdir command will automatically expand the directory if
3465 necessary. (Addresses Debian Bug: #217892)
3467 Fixed a bug in debugfs so that copying a file from /dev/null uses the
3468 correct mode bits. (Addresses Debian Bug: #217456)
3470 If the environment variables DEBUFS_PAGER and PAGER are not set,
3471 debugfs 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)
3475 Debugfs will now support 2.6 device numbers where the major or minor
3476 number may be larger than 255. (Addresses Sourceforge bug #865289)
3478 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)

3483 Fix regression tests so they work correctly when e2fsprogs is compiled
3484 with configure --disable-htree.
3486 Fix bug in uuid library when there is no network card and the library
3487 is generating a time-based uuid. The random MAC address was not
3488 correctly generated to be a multicast address.
3490 Add compile_et extensions from Heimdall that were missed the first time
3493 Fix bug in badblocks when using O_DIRECT; we need to make sure that
3494 we're reading from an offset which is page aligned. For read-only and
3495 read-write tests, we try to recover after an error so that we can
3496 continue reading on page-aligned boundaries. (Addresses Debian Bug
3499 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
3502 Updated and clarified various man pages. (Addresses Debian Bug
3503 #206845, #222606, #214920, #232406)
3505 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
3507 Fixed various Debian packaging issues (see debian/changelog).
3512 Fixed a build problem so that e2fsprogs would compile with the
3513 --enable-profile option to configure selected. (Addresses Sourceforge
3516 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
3517 Bugzilla Bug #112448)
3519 Centralize code which calculates the location of the superblock
3520 and block group descriptors so that it is in a single library routine.
3522 Added two new functions, ext2fs_file_open2() and
3523 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3525 Fix compile_et to output the correct prototype for
3526 initialize_xxx_err_table_r() in the header file. (Addresses Debian

3531 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3532 present. This is for when we try stuffing an int into void * pointer.
3534 Fix type-punning which can cause gcc 3.x to miscompile code by getting
3535 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3536 and 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
3538 modify the EVMS interfaces.
3540 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3541 aid build process on systems can use invoke GNU make as "gmake".
3543 Added regression testing for mke2fs.

3547 Fixed various compiler warnings.
3549 Add portability fixes for FreeBSD and for using fsctl under Darwin to
3550 support ext2 ioctl's.
3553 E2fsprogs 1.34 (July 25, 2003)
3554 ===============================
3556 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3557 a tight loop while waiting for a child fsck to exit in some cases.
3558 This burns CPU times which slows down the low-level filesystem check.
3560 Added code to mke2fs to assure that the default block size for a
3561 filesystem is at least as big as the sector size of the device, if it
3564 Changed mke2fs and resize2fs to round the default size of a filesystem
3565 to be an even multiple of the VM pagesize in order to avoid a Linux
3566 kernel bug introduced when the storage of the buffer cache was moved
3567 into the page cache.
3569 Mke2fs will warn the user when creating a filesystem with journaling
3570 and a blocksize greater than 4096. (Addresses Debian bug #193773)
3572 Fixed a bug in resize2fs which caused it to fail on filesystems with a
3573 non-empty bad block list. Resize2fs now discards any blocks on the
3574 badblock list which are no longer part of the filesystem as the result
3575 of a filesystem shrink. (Note: this means that shrinking and then
3576 enlarging a filesystem is no longer a reversible operation;
3577 information about bad blocks in the part of the filesystem which is to
3578 be chopped off will be lost.)
3580 Changed resize2fs so the user can use prefixes to specify the units of
3581 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3582 and to make the error and informational messages explicitly display
3583 the blocksize used by the filesystem, in order to avoid confusion.
3584 (Addresses Debian bug: #189814)
3586 Added a new debugfs command, dump_unused, which dumps the contents of
3587 all unused blocks to stdout. (Useful as an emergency try-to-find
3588 deleted data command.)
3590 Added a new debugfs command, imap, which prints the location of a
3591 specified inode in the inode table.
3593 Fixed a bug in the badblocks program which caused it to use one bit of
3594 randomness in its non-destructive read/write test, instead of using a
3595 full 8 bits of randomness.
3597 Added a new option (-t) to badblocks, which allows the user to control
3598 the test pattern(s) used when checking a disk.
3600 The blkid probe function now more correctly detects UDF filesystems.
3602 Fixed a bug in the blkid library which caused it to not update its
3603 cache if a filesystem changes from having a label to not having a
3606 Fixed a bug in the blkid library wihch could avoid an infinite loop
3607 in blkid_find_dev_with_tag() if /proc is not mounted and there the
3608 /etc/blkid.tab file has not yet been created.
3610 Fixed the badblocks program so that the destructive read/write test
3611 honors the -c option, and to use O_DIRECT when possible to avoid
3612 thrashing the system block buffer cache.
3614 Fixed 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
3620 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3621 simplify the statistics reporting in e2fsck.
3623 Changed configure.in so that its defaults for *BSD systems no longer
3624 build an fsck wrapper, and not to install in /usr/local by default.
3626 Fixed some minor spelling errors/typo's in e2fsck and the configure
3629 Fixed various Debian packaging issues (see debian/changelog).
3631 Updated and clarified man pages. (Addresses Debian Bug #195616)
3636 Fix gcc -Wall nitpicks.
3638 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3639 NLS support by default. (Added partial workaround for gettext/Darwin
3640 incompatibility problems.)
3642 Added full MIT KRB5 and Himdall compaibility support to the com_err
3643 library and the compile_et program. (Addresses Debian bug #191900)
3645 Added the blkid_known_fstype() function to the blkid library, which
3646 returns true if it is passed a filesystem type which is recognized by
3647 the blkid probing functions.
3649 Improved the documentation for the blkid library.
3651 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3652 returns the hardware sector size of a device, if it is available.
3654 Added a dependency in the blkid library's .so file to the uuid
3655 library, since the former uses the latter. (Addresses Debian bug
3658 Added --with-diet-libc and --disable-evms to the configure script.
3660 Fixed a minor memory leak in the badblocks program.
3662 Fixed a portability problem in tune2fs --- not all systems have strptime().
3664 Fixed a portability problem in debugfs with the use of getopt() more
3665 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3668 Add support Windows support to ext2fs_get_device_size().
3670 Added (normally disabled) debugging code to the Unix I/O manager which
3671 causes it to disable all userspace caching if the NO_IO_CACHE is
3674 Changed the test I/O manager so it can always be linked into e2fsck,
3675 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3676 configure script. The test I/O manager will only print any debugging
3677 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3678 variables are set, which specifies which I/O operations are logged and
3679 a block number to watch, respectively. The log messages are sent to
3680 stderr by default, unless a filename is specified via the
3681 TEST_IO_LOGFILE environment variable.
3684 E2fsprogs 1.33 (April 21, 2003)
3685 ===============================
3687 Added a new utility program, logsave, which captures the output of a
3688 command in a log file, even if the containing directory hasn't been
3689 mounted yet (in which case the it saves the output in memory until it
3690 can write out the logfile). This is useful for capturing the
3691 output of fsck during the boot sequence.
3693 Fixed some portability problems that were causing problems under
3694 the Cygwin32 environment.
3696 Mke2fs now interprets a negative number to the -b option as a minimum
3699 Fixed a bug in mke2fs which was incorrectly checking the argument to
3700 the -g option if the default block size was used. (Addresses Debian
3703 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3704 it can not find filesystem checkers for jfs, reseirfs, and xfs.
3706 E2fsck now updates the global free block and inode counters from the
3707 block group specific counters quietly. This is needed for an
3708 experimental patch which eliminates locking the entire filesystem when
3709 allocating blocks or inodes; if the filesystem is not unmounted
3710 cleanly, the global counts may not be accurate.
3712 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3713 2.0 is not yet supported; this only pulled in the bug fixes: fixed
3714 possible hangs caused by bugs in calling waitpid, and not setting the
3715 pipe to non-blocking mode; also fixed a file descriptor leak; made
3716 sure all functions call log entry/exit functions.)
3718 Badblocks now flushes its output file as bad blocks are discovered.
3720 The uuid library is now more paranoid about assuming the correctness
3721 of the /dev/random device; it mixes in a stream of bytes from
3722 random/srandom, just in case.
3724 Update Debian files to reflect the fact that I am now the Debian
3725 maintainer of e2fsprogs. Other various Debian-specific packaging
3728 Move the source tarball generation functions from the top-level
3729 makefile to the util/gen-tarball script.
3731 Updated the Turkish .po translation file.
3733 Added Heimdal and MIT krb5 extensions to the com_err library to make
3734 it more compatible with com_err libraries from those distributions.
3736 Changed dumpe2fs to always display the superblock fields relating to
3737 the journalling and/or directory indexing feature even if those
3738 features are not enabled.
3740 Updated and clarify copyright statement vis-a-vis alpha releases of
3743 The ss library will now try to dynamically link to the readline
3744 library and use it if it is present in the system. This means that
3745 the debugfs program now has line editing and history features. The
3746 SS_READLINE_PATH environment variable is used to find a readline or
3747 readline-compatible library.
3749 E2fsck now finds most duplicate filenames (all when rebuilding all
3750 directories via the -D option) and offers to delete or rename
3751 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3753 Fix bug in e2image. When writing out a raw image file, include data
3754 blocks from symlinks that do not store the symlink within the inode.
3756 Fix bug in resize2fs which incorrectly moved the block and inode
3757 bitmaps for sparse superblock filesystems and incorrectly marked
3758 blocks as in use. (Addresses Debian bug #174766)
3760 Added a new shared library, the blkid library, which efficiently
3761 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3762 and UUID filesystem specifiers without needing to search all of the
3763 devices in the system. Instead, the device is looked up in a cache
3764 file, and then verified to make sure the blkid cache is correct.
3766 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3767 the device name, using the blkid library. (Addresses Debian bugs
3770 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3771 used for spaces in device labels.
3773 Removed 32-bit limitations for debugfs's dump command.
3775 If the user specifies a large number of inodes, Mke2fs will
3776 automatically adjust the number of blocks per group to find a valid
3777 set of filesystem parameters.
3779 Add workaround to detect broken MD devices where when some of the
3780 underlying devices are marked read-only, writes to the MD device are
3781 silently dropped. E2fsck will detect if there is an attempt to run
3782 the journal twice, and abort with an error if this is the case.
3783 (Addresses IBM Bugzilla bug #1226)
3785 E2fsck will print an error if more than one of the -p/-a, -n or -y
3786 options are specified.
3788 E2fsck will fix HTREE corruptions in preen mode, without stopping the
3789 boot process. This is needed because the 2.4 ext2 filesystem
3790 accidentally had the INDEX_FL backwards compatibility code removed.
3792 Mke2fs no longer creates filesystems with the dir_index flag set by
3793 default; the user has to specifically request it.
3795 Update and clarified various man pages. (Addresses Debian bugs
3796 #173612, #175233, #175113, and #170497, #185945, #188318)
3798 Created man page for the mk_cmds program (from the libss library).
3803 Fix various gcc -Wall nits.
3805 Fixed a lot of portability problems that caused e2fsprogs not to build
3806 successfully under Solaris and Apple/Darwin.
3808 Fixed a Makefile dependency to allow building e2fsprogs using parallel
3811 Changes to create a subset distribution which consists only of the
3812 et, ss, uuid, and blkid libraries. The configure script and top-level
3813 makefile were changed to support working with a subset distribution.
3815 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3816 actually used, and might people who are looking for
3817 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3819 Updated debian files to fix a number of Lintian warnings.
3821 Updated config.guess and config.sub with newer versions from the FSF.
3823 Removed unnecessary libraries from being linked into the fsck, lsattr,
3824 chattr, and blkid executables.
3826 E2fsprogs 1.32 (Nomvember 9, 2002)
3827 ==================================
3829 Fixed a bug in the Unix I/O routines which caused needless writebacks
3830 of clean blocks from the unix_io cache (they were erroneously marked
3831 as being dirty, so they were getting written back to disk before
3832 getting evicted from the disk cache). This was harmless, but it
3833 significantly slowed down e2fsck.
3835 Made some other minor optimizations to the Unix I/O routines to save a
3836 small amount of CPU time.
3838 Updated internationalization files.
3841 E2fsprogs 1.31 (Nomvember 8, 2002)
3842 ==================================
3844 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3845 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3846 handling for child process that die unexpectly. Add a hack to force
3847 mkfs to create filesystems that won't cause problems with hardware
3848 that has 2k or 4k minimum blocksize requirements. Read from child
3849 processes in non-blocking mode, so that the GUI continues to update.
3851 Fix e2fsck so that it returns the appropriate exit code when the root
3852 filesystem has been changed, so that system's rc scripts will be told that
3853 the system needs to be rebooted.
3855 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3856 was set, some of the descriptor blocks that should have been written
3857 out were getting skipped.
3859 Changed e2fsck to force out changes to the backup copies of the
3860 superblock and block group descriptors when important changes are made
3861 to those data structures.
3863 Fix a bug where e2fsck could erroneously mark a filesystem as being
3864 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3865 introduced in e2fsprogs 1.28.)
3867 If journal debuging is enabled using --enable-jbd-debug, the debugging
3868 level is now set via the E2FSCK_JBD_DEBUG environment variable.
3870 If byteswapping support is disabled using configure --disable-swapfs,
3871 skip the tests which depend on byte-swapping, so that "make check"
3874 Lshattr will now display the indexed directory flag. Also, some of
3875 the more esoteric compression flags are supressed unless compression
3876 support has been enabled.
3881 E2fsprogs 1.30 (October 31, 2002)
3882 =================================
3884 When resizing a filesystem, and inodes need to moved, resize2fs will
3885 update the inode's ctime field, and the mtime field of the containing
3886 directories, so that incremental backups using dump/restore will work
3889 In order to avoid spurious errors, e2fsck wil check the last
3890 superblock write time to determine whether or not it can safely use
3891 the LOW_DTIME checks to determine if there are inodes on the orphan
3892 inode linked list that had somehow gotten disconnected. (Addresses
3893 Sourceforge bug #620980)
3895 Partition in /proc/partitions that being with the string "lvm" are
3896 considered real partitions even if they do not end with a number.
3898 Fixed a bug in the the uuid generation function, where if /dev/urandom
3899 is not present, but /dev/random is, and there isn't sufficient
3900 entropy, the get_random_byte function could spin a loop forever.
3902 E2fsck, mke2fs, etc. will now reliably notice when image files are
3903 mounted using the loopback interface. (Addresses Sourceforge bug
3906 When flushing buffers (as is done by badblocks, for example) check to
3907 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3908 FDFLUSH ioctl which causes the MD device driver which causes confusing
3909 syslog messages about obselete ioctl messages. (Addresses Sourceforge
3912 Debugfs's write command now checks to see if the destination filename
3913 exists before creating it. (Addresses Sourceforge bug #478195.)
3915 When installing man pages, search for compressed man pages using all
3916 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3918 Fixed a bug in fsck where multiple filesystems specified on the
3919 command were not being checked in parallel due to a logic bug
3920 introduced to support the FSCK_MAX_INST environment variable.
3922 We have added a new superblock field, s_mkfs_time, which indicates
3923 when a filesystem was created. It is set via mke2fs, and printed out
3924 by dumpe2fs, but is not actually touched by the kernel.
3926 Dumpe2fs has been made more robust by not aborting if there is an
3927 error reading the block/inode bitmaps; instead it will still print out
3928 the location of the block/inode bitmaps and inode table.
3930 Add support for the an alternative block group descriptor layout which
3931 allows for on-line resizing without needing to prepare the filesystem
3932 in advance. (This is the incomat feature flag meta_bg.)
3934 Add support for storing default mount options in the superblock, so
3935 that the filesystem can be mounted with specific mount options without
3936 needing to specify them on the mount command line or in the /etc/fstab
3939 Add support for a new inode flag, which is to be used for indicating
3940 the top of directory hierarchies for the Orlov block allocator.
3942 Fix e2fsck so that if it creates the lost+found directory, it does so
3943 with the more apporpriate permissions of 0700. Also change
3944 mklost+found so that it also creates the directory 0700.
3946 Fixed format bug in e2fsck if NLS is in use.
3948 Add a German translation for e2fsprogs's NLS support.
3950 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3951 the beginning of the inode table. This won't matter much, since if
3952 there is a bad block at the beginning of the inode table, the root
3953 directory won't be available. But at least e2fsck won't crash in this
3956 Fixed endian problems in the htree code for e2fsck and debugfs.
3958 When byte-swapping a filesystem on a PPC architecture, byte-swap the
3959 bitmaps since the historical big-endian ext2 variant had byte-swapped
3960 bitmaps, and the ext2fs library assumes this. This fixes the
3961 regression test suite on PPC machines.
3963 Fix e2image so that it handles a bad block in the inode table
3966 E2fsck now uses a more sophisticated algorithm to salvage corrupted
3967 directories that recovers more information in the corrupted directory
3970 E2fsck now performs additional consistency checks on indexed (HTREE)
3973 Fix bug where efsck might get confused about whether a completely
3974 empty directory block is an empty leaf block or an interior htree
3975 node. This could cause e2fsck to get confused into think that a valid
3976 indexed directory was corrupted.
3978 E2fsck no longer creates an empty directory entry at the end of a
3979 directory block when optimizing a directory. This would cause some
3980 earlier versions of the dxdir kernel code to corrupt the directory
3981 when attempting to split a node containing an empty directory entry.
3983 E2fsck could sometimes in rare circumstances leave the indexed flag
3984 set after a small directory was optimized by compressing it instead of
3985 indexing it. (This should never happen in real life, since
3986 directories that small wouldn't have been indexed, but better safe
3989 E2fsck now only updates the master superblock in all cases. This
3990 slightly shortens its run time.
3992 Ext2ed can deal with directory entries of length 0; previously it
3993 would get stuck in an infinite loop.
3995 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3996 specifiers. (Sourceforge patch #613447)
3998 Badblocks will now work correctly on read-only devices such as
3999 CD-ROM's. (Sourceforge patch #600451)
4001 Updated and clarified man pages. (Addresses Debian bug #167108)
4004 E2fsprogs 1.29 (September 24, 2002)
4005 ===================================
4007 Fixed a bug in e2fsck which could corrupt a directory when optimizing
4008 it (via the -D option) or rebuiliding the hash tree index with a 1 in
4009 512 probability, due to a fence post error.
4011 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4014 Mke2fs now enables the directory indexing flag by default. (Since
4015 this is a compatible feature flag, it's safe to do so.)
4017 Tune2fs will support setting the directory indexing feature flag. It
4018 will automatically set up the default hash algorithm and hash seed
4019 fields in the superblock.
4021 If the bone-headed user enters the root filesystem twice in
4022 /etc/fstab, the -R option which skips the root filesystem will skip
4023 all of them. (Addresses Debian bug #159423). Note! This is not a
4024 precedent for dealing intelligently with any other kind of doubled
4025 entry in /etc/fstab!
4031 Removed perror declaration in lib/et/internal.h. All modern systems
4032 can be expected to define perror() these days. Besides, the lib/et
4033 code wasn't using perror at all anyway. :-)
4036 E2fsprogs 1.28 (August 31, 2002)
4037 ================================
4039 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4040 for setting the htree flag is not included yet, although it can be
4041 manually turned on via the debugfs program.
4043 Clarified e2fsck error message which is printed when it cannot find
4044 sufficient contiguous block when relcating filesystem metadata.
4046 Added support for building an EVMS plugin module for ext2/3. This
4047 module is substantially the same as the EVMS module shipping with EVMS
4048 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4049 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4050 if the configure --enable-old-evms flag is given.
4052 Fsck will search through EVMS volumes when trying to resolve
4053 filesystem specifications such as LABEL=xxx or UUID=xxx.
4055 Added a new utility program, /sbin/findfs, which will return
4056 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4059 Update and clarified various man pages. (addresses Debian Bug #145044,
4060 #146437, #131350, #151990, #144621, #141938)
4062 If there are no filesystems specified on fsck's command line, fsck now
4063 treat that as if the -As options were given. Previously it would
4064 simply do nothing. (Addresses Debian Bug #153102)
4066 Mke2fs no longer treats a failure to be able to clear the MD signature
4067 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4070 The e2p library functions (which are used by lsattr and chattr) now
4071 double check to make sure the file is a regular file or directory
4072 before attempting to use the ext2 ioctls. Some device drivers
4073 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4074 (Addresses Debian Bug #152029).
4076 The extended attribute handling has been updated to correspond with
4077 the latest V2 bestbits ACL code.
4079 Fixed bug in e2fsck which caused it to not clear the dtime field when
4080 processing truncated inodes on the orphan list. This could cause data
4081 loss(!) if a filesystem is rebooted before a truncate has been
4084 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4085 algorithms. This makes e2fsck much faster in the case of severely
4086 corrupted filesystems where a large number of blocks are claimed by a
4087 large number of inodes. (Thanks to the 2.5 IDE device driver for
4088 inspiring this work.)
4090 Resize2fs has been significantly sped up when shrinking and expanding
4091 a filesystem by a very small number of blocks (for example, when EVMS
4092 is converting a partition to be an EVMS legacy volume).
4094 Added a new option to e2fsck, -D, which will optimize or compress all
4095 of the directories in the filesystem.
4097 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4098 properly clean up and only exit at safe points. Fsck will pass
4099 SIGINT/SIGTERM to its child processes, and wait until they have all
4100 exited before it exits.
4102 The uuid parsing code in the uuid library now properly complains when
4103 an illegally formated uuid is presented to it. (Addresses Debian bug
4106 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4107 and 2.4.17, since the workaround can cause problems when using a 2.4
4108 kernel with an old version of glibc built with the 2.2 headers.
4110 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4111 superblock used by other filesystems. (Addresses Debian bug #147256.)
4113 Added support for the synchronous directory feature written by Andrew
4116 The debugfs program can delete directories using the rmdir command.
4118 Add support for 8k and 16k filesystems (for systems with page sizes
4119 that are greater or equal to 8k or 16k, respectively). Note that
4120 these filesystems can not be mounted on x86 systems, or other systems
4121 with only 4k page sizes, due to limitations in the current Linux VM
4124 Resize2fs requires that the filesystem state be valid and have no
4125 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4126 required that the last fsck time be greater than the last mount time.)
4128 Configure now defaults the man pages directory to /usr/share/man on
4131 E2fsck now offers to truncate inodes which contain too many blocks (so
4132 that i_blocks would overflow. Also fixed handling of large sparse
4135 E2fsck now more completely checks for symlink validity, including
4136 requiring NULL termination and length checks.
4138 E2fsck will offer to try forcing a disk write to remap a bad block
4139 after finding a read error when reading a filesystem metadata block.
4141 Fixed a bug in debugfs which caused the -b and -s options to crash
4142 debugfs, as well as breaking the testb, setb, and clearb functions.
4144 Added a bmap command to debugfs which calculates the logical to
4145 physical block mapping for a particular inode.
4147 Fixed a bug in code which checked to see if a device was mounted which
4148 sometimes (rarely) failed in the case of a plain file.
4150 Fixed a bug in resize2fs where when it reported an error, it would
4151 print a message erroneously indicating that the filesystem had been
4152 resized before it aborted.
4154 When resizing a plain file which is smaller than the requested size,
4155 resize2fs will attempt to extended the file so that programs like
4156 e2fsck will not complain that the file is too small.
4158 Resize2fs will print the actual new size of the filesystem when it is
4161 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4162 information on big-endian systems.
4168 Fixed collisions with C++ reserved words.
4170 Added portability fixes for building e2fsprogs on the HURD and AIX.
4172 Added the ext2ed program for creation of test cases. (ext2ed has many
4173 limitations and bugs which make it unsuitable for production use.)
4175 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4176 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4177 name_len field is byte swampped on big-endian machines, since in the
4178 V2 structure, name_len is a char field which is doesn't need to be
4179 byte swapped --- except if an old-style kernel had byte-swapped the
4180 name_len field as part of the V1 structure.
4183 E2fsprogs 1.27 (March 8, 2002)
4184 ==============================
4186 The warning messages for mke2fs now go to standard error.
4188 Fixed to make sure "make check" runs all of the test programs with
4189 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4191 The mke2fs program checks the boot sector for the BSD disk label, and
4192 avoids erasing it if it is there.
4194 Fixed a bug in e2fsck which caused it to core dump if the journal
4195 inode was missing when it was supposed to be there.
4197 E2fsck now prints ranges in pass 5 when printing deltas for the block
4200 Debugfs's "ls -l" command now will print out the file type information
4201 in the directory entry.
4203 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4204 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4206 Debugfs can now examine the experimental directory indexing
4209 Fixed bug in debugfs which caused it to core dump if modify_inode is
4210 called without an open filesystem.
4212 The debugfs lsdel command now runs its output through a pager first.
4214 When installing manual pages, remove the compressed manual pages first.
4216 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4218 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4219 actually broke things on mips32, sparc32, and Alpha platforms.
4221 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4222 (which is required by the newer libintl libraries).
4227 Fixed various gcc -Wall complaints.
4229 Fixed a few memory leaks in the e2fsck journaling code, and in the
4230 ismounted code checking for a swap device.
4232 Add new inode I/O abstraction interface which exports an inode as
4235 Exported ext2_file_flush as a public interface.
4237 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4239 Lots of small random portability fixes to make e2fsprogs build under
4240 AIX --- even without the 5L compatibility toolkit, and even using the
4241 uber-crippled AIX native C compiler.
4244 E2fsprogs 1.26 (February 3, 2002)
4245 =================================
4247 Dumpe2fs will keep going now if the bad block inode can't be read.
4248 (Previously it stopped with a fatal error.)
4250 E2fsck will now give an opportunity to run the journal even if the
4251 recovery flag is not set. This is the default behaviour if e2fsck is
4252 using a backup superblock, since the needs_recovery flag will never be
4253 set in the backup superblock copies.
4255 E2fsck now automatically finds the backup superblock/group descriptors
4256 even when the primary superblock is completely destroyed for 2k and 4k
4257 filesystems. (Previously it just guessed/assumed that we were dealing
4258 with a 1k filesystem in that case, and users had to manually specify
4259 the backup superblock number.)
4261 Fixed a bug in e2fsck where it dereferences a null pointer when there
4262 is a problem opening a filesystem in preen mode.
4264 E2fsck now handles external journals correctly; previously it trashed
4265 the external journal device if the journal needed to be replayed.
4267 Work around ulimit incompatibility problem caused by recent 2.4
4268 kernels; the unix IO module will automatically try to set any resource
4269 limits to be infinite on startup.
4271 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4272 bitmap if it wasn't present and the blocksize was 2k or 4k.
4273 (Addresses Debian Bug #116975)
4275 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4276 clearing the new V2 fields if they do not make sense or if the ext3
4277 superblock is version 1 superblock.
4279 E2fsck will automatically relocate the ext3 journal from a visible
4280 file (i.e., /.journal) to an hidden inode if the filesystem has been
4281 opened read/write. This allows the users to add a journal while the
4282 filesystem is mounted, but the next time the system is rebooted, the
4283 journal file will disappear. This avoids problems with backups,
4284 stupid operators with superuser bits, etc.
4286 Fix 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.
4289 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4290 automatically identify reiserfs filesystems.
4292 The number of processes spawned by fsck can now be limited using the
4293 FSCK_MAX_INST environment variable.
4295 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4296 should be searched for UUID and label information.
4298 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4299 limit if at all possible, when opening a block device. (The filesize
4300 limit shouldn't be applied against writes to a block device.)
4302 In mke2fs and e2fsck, specifying the -c option twice will now do
4303 a read/write test on the disk. Update the man pages to encourage
4304 using the -c option, and to discouraging running badblocks separately,
4305 since users tend to forget to set the blocksize when running
4308 Mke2fs now automatically clears the immutable attribute on a
4309 pre-existing .journal file left over from a previous failed attempt to
4310 add a journal to an alreadyy-mounted filesystem.
4312 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4315 Mke2fs now creates the lost+found directory with permissions of 0700,
4316 so that files that had previously lived in protected directory are
4317 safe if they get dropped in lost+found and the system administrator
4318 doesn't deal with immediately. (Addresses Debian #bug 118443)
4320 Mke2fs and e2fsck (and all programs that use the
4321 ext2fs_check_if_mounted function) will now properly identify that a
4322 device is mounted, even in cases where devfs has confused things with
4323 multiple devices names with the same identity, or if a dim-witted
4324 system administrator has done something stupid like creating device
4325 file aliases in their home directory. Also now checks for swap devices
4326 by using /proc/swaps. (Addresses Debian bug #106622)
4328 Added a new option (-T) to tune2fs which sets the time a filesystem
4331 Speed up e2image when creating sparse raw image files by optimizing
4332 away excess lseek() system calls.
4334 Fix support of large (> 2GB) files when used as a filesystem in
4335 mke2fs, tune2fs, debugfs, and findsuper.
4337 Debugfs's stat and icheck commands now properly deals with large (>
4340 Debugfs's set_super_value command now prints out the list of valid
4341 superblock fields which can be set using the command.
4343 Debugfs's rm and kill_file command now updates the superblock free block
4344 and inode counts, thus keeping the filesystem consistent.
4346 Debugfs's lsdel command now takes an optional argument which allows
4347 the user to only see the most recently deleted files.
4349 A new command (undel) was added to debugfs which automates
4350 undeleting a deleted inode and linking it back to a directory.
4352 Debugfs's ls command now takes a new option, -d, which lists
4353 deleted directory entries.
4355 Debugfs's testb, freeb, setb, and find_free_block commands now take an
4356 optional count argument.
4358 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4359 be used to signal that a particular inode should not be eligible for
4360 tail-merging --- this is needed for programs like LILO.
4362 The findsuper (an unreleased, uninstalled utility program) has been
4363 improved to add extra validity checks and to add a progress meter.
4364 (It is still an unsupported program; the officially supported way to
4365 recover from a trashed partition table is to use gpart; findsuper is
4366 for wizards only. :-)
4368 Debugfs was fixed to compile with "configure --disable-swapfs".
4370 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
4372 Added new translation file for Turkish.
4377 Fix general gcc -Wall complaints.
4379 E2fsprogs (mostly) works with the dietlibc.
4381 The programming texinfo file has been expanded to include description
4382 of additional libext2fs functions. (Still not compeltely done, but a
4383 lot of the more important functions have been documented.)
4385 Added a umask structure to struct_ext2_filsys, which currently only
4386 modifies the behaviour of ext2fs_mkdir(), but if we add any file
4387 creation functions to libext2fs, we should also make sure they respect
4390 The build-rpm script was fixed to be a bit more safe.
4392 The tests' Makefile now has a way of automating test case creation
4393 for e2fsck, using "make testnew".
4395 Created a new function, ext2fs_dir_iterate2 which passes more
4396 information to the callback function (identical to the one used by
4397 ext2fs_dblist_dir_iterate). The directory iterator functions take a
4398 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4399 directory entries. If the directory entry is deleted, the callback
4400 function will be called with the entry paraemter set to
4401 DIRENT_DELETED_FILE.
4403 Added new functions, ext2fs_inode_alloc_stats and
4404 ext2fs_block_alloc_stats, which takes updates block/inode allocation
4405 statistics in the bitmaps, block group descriptors, and superblock
4406 when inodes or blocks are allocated or deallocated.
4409 E2fsprogs 1.25 (September 20, 2001)
4410 ===================================
4412 This is primarily a bug-fix release; no new features were added, but
4413 there are a number of embarassing bug fixes and cleanups applied.
4415 Fix a bug mke2fs which causes stack garbage to be written to disk when
4416 zapping disk sectors. (This bug could cause mke2fs to core dump for
4417 some kernels, I suspect with security enhancement patches.)
4419 Remove unneeded #include of <linux/config.h> which was breaking
4420 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
4422 Updated tune2fs man page to reflect the fact that adding or removing a
4423 journal doesn't require running e2fsck.
4425 Remove use of AC_REQUIRE from autoconf which had been used to prevent
4426 AC_CANONICAL_HOST from being called twice; unfortunately this causes
4427 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4428 used outside of autoconf macros. Fortunately, it doesn't seem to be
4429 necessary any more, anyway.
4431 E2fsck will now not fall back to an alternate superblock if the user
4432 specifies the superblock location explicitly on the command-line.
4433 This allows easier recovery from a situation where the primary
4434 superblock and block groups are slightly corrupted, but the backup
4435 superblocks are completely broken.
4437 Fix problem which caused compile_et and mk_cmds to blow up if
4438 e2fsprogs was in a directory with a pathname that contained spaces.
4440 We are now more paranoid about checking the entry in /etc/mtab to make
4441 sure the filesystem is really mounted, since some broken distributions
4442 (read: Slackware) don't initialize /etc/mtab before checking non-root
4443 filesystems. (Slackware also doesn't check the root filesystem
4444 separately, and reboot if the root filesystem had changes applied to
4445 it, which is dangerous and broken, but there's nothing I can do about
4448 Make UUID library C++ friendly by adding appropriate extern "C"
4449 declarations and using const in the function declarations.
4451 Fix up the com_err texinfo file so that it can product a valid info
4452 file (previously, it could only be used to generate paper
4453 documentation using texinfo.tex).
4456 E2fsprogs 1.24a (September 2, 2001)
4457 ===================================
4459 Fix brown-paper bug in mke2fs which caused it to segfault when
4460 printing the version string.
4463 E2fsprogs 1.24 (August 30, 2001)
4464 ================================
4466 Revert the BLKGETSIZE64 support, since for some distributions, this
4467 ioctl has been used by an unofficial kernel patch to update the last
4468 sector on the disk, and this was causing disk corruption problems as a
4471 Mke2fs is now more careful about zapping swap space signatures and
4472 other filesystem/raid superblock magic values so that programs like
4473 mount who try to use hueristics to determine the filesystem type of a
4474 partition are less likely to be confused.
4476 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4477 regular file (since Andreas Dilger's on-line resizing tools will set
4480 Fixed some minor texinfo, man pages nits for spelling errors,
4481 texinfo warnings, etc. (Addresses Debian bug #110621.)
4483 E2fsprogs program no longer print the filesystem version number
4484 (i.e. 0.5b), since it only confuses people and doesn't serve any real
4487 E2fsck will once again compile under libc5, since it will supply its
4488 own version of strnlen if necesssary.
4490 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4491 when specifying the external journal device. tune2fs will also search
4492 devices looking for the externla journal debice when removing.
4494 E2fsprogs 1.23 (August 15, 2001)
4495 ================================
4497 Add initial support for extended attributes (EA); e2fsck will
4498 correctly handle a filesystem with EA's and check the EA blocks for
4501 E2fsck's symlink sanity checking has been cleaned up. It now checks
4502 the i_size value of fast symlinks, and checks for immutable flags
4503 being set of symlinks, etc.
4505 E2fsck now offers to clear inodes which are special files that have a
4506 non-zero i_blocks or i_size field. (The i_size field check was in the
4507 previous version of the code, but due to a bug it didn't offer to
4508 clear the inode unless i_size and i_size_high were both non-zero.)
4510 E2image can now create "raw" image files, which only contain the
4511 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4512 debugfs, etc., can be run directly on the raw image file.
4514 Add support for the 64-bit block device patches.
4516 Fixed bugs in creating external journals with a 1k blocksize.
4518 Add initial support for external journals (so long as the external
4519 journal only supports a single filesystem) in e2fsck.
4521 Remove requirement for needing to run fsck on a filesystem after
4522 removing a journal (either internal or external).
4524 The man pages now document how to create and manage external journals.
4526 Speed up the check of an ext3 filesystems by avoiding a needless flush
4527 of all of the superblock and block group descriptors.
4529 Speed up creating an internal journal using tune2fs in the case where
4530 the filesystem has a lot blocks already allocated.
4532 Tune2fs has been fixed to make sure that only error messages go to
4533 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4535 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4536 now not set the sparse_super feature. (Addresses Debian bug #108165)
4538 Add support in fsck for the filesystem type "auto".
4540 Fsck -A will not try to interpret device names for filesystems which
4541 have a pass number is 0. (Addresses Debian bug #106696).
4543 Fsck prints a warning message if now valid filesystems are passed to
4544 it. (Addresses Debian Bug #107458.)
4546 E2fsck now gives an explicit warning if there filesystem still has
4547 errors at the end of the run. (Addresses Debian bug #104502)
4549 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4550 reflects an error. E2fsck will also not run the orphan list if the
4551 filesystem contains errors, since the orphan list might be corrupted.
4553 E2fsck now prints the number of large files when given the -v option.
4555 Fixed minor memory leaks in e2fsck.
4557 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4560 E2fsprogs 1.22 (June 22, 2001)
4561 ==============================
4563 Fixed a bug in e2fsck's handling of orphan inodes which are special
4564 files (i.e., block/character device files, named FIFO's, etc.).
4566 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4567 tune2fs to fail at adding a journal to a mounted filesystem.
4569 Fixed 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).
4576 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4581 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4582 ioctls, and allow them to be defined for non-i386 platforms.
4584 The uuid.h header file is now protected against multiple inclusions.
4586 E2fsprogs is now being developed using BitKeeper. Changed the test
4587 scripts to deal with BK's stripping CR characgters from text files,
4588 and changed the top-level Makefile.in to avoid including BitKeeper
4589 files when generating the source tarball.
4592 E2fsprogs 1.21 (June 15, 2001)
4593 ==============================
4595 Added new configure flags which allow a subset e2fsprogs to be built;
4596 this is most useful for boot floopies, since the resulting shared
4597 libraries and programs are slimmed down by removing features that
4598 aren't necessary for a boot floppy. The new flags that were added
4599 are: --disable-swapfs, which removes support for byte swapping old
4600 legacy PPC/68k filesystems, --disable-debugfs, which removes support
4601 for debugfs from the libext2fs library, --disable-imager, which
4602 removes support for the e2image program, and --disable-resizer, which
4603 removes support for resize2fs.
4605 E2fsck now prints the number of mounts or days elapsed since the last
4606 check when e2fsck is forced to check an otherwise clean filesystem.
4608 Tune2fs now prints an informative message about how often a filesystem
4609 will be checked when adding a journal to the filesystem, to remind the
4610 user that he/she may want to adjust those parameters using tune2fs
4613 Worked around hurd brain-damage which causes e2fsck to sometimes
4614 believe 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
4618 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4619 erroneous error with the -F option was specified.
4621 Fixed a ext3 recovery bug in the revoke handling; synchronized with
4624 Fixed two bugs in e2fsck's handling of dup block handling, dealing
4625 with relatively uncommon edge cases: a directory with an indirect
4626 block which is claimed by another file, and when the last inode in the
4627 filesystem has blocks claimed by another file.
4629 E2fsck now checks to see if the i_size field of a fast symlink is too
4630 big, and offers to clear the symlink if so.
4632 E2fsck now checks to see if i_size_high of special files is non-zero,
4633 and offers to clear i_size_high.
4635 Fix e2fsck's handling of incompatible journal flags so that the user
4636 has chance to abort, and then has the option to clear out the journal
4637 entirely. (Addresses Debian bug #98527.)
4639 Fixed a bug in fsck which could cause it to core dump if a mix of
4640 standard and non-standard device names are used in /etc/fstab.
4641 (Debian bug #100559)
4643 Fixed a bug in debugfs which caused read errors when copying a file to
4646 The debugfs set_super_value command can now modify the s_lastcheck field.
4648 Fixed a bug in lsattr and chattr which was accidentally introduced in
4649 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
4650 directories correctly because the change modified the layout of struct
4651 dirent to be incompatible with the libe2p shared library.
4653 Cleaned up the mke2fs manual page and included a discussion about why
4654 it's good to periodically check the filesystem even when journaling is
4660 Fix general gcc -Wall complaints.
4662 The types needed by the ext2 header files are now provided by
4663 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4665 Integers are now preferred to longs when trying to find a 32-bit type
4666 in ext2_types.h. Also, if linux/types.h has already been defined,
4667 don't try to redefine the types.
4669 Fixed make depend script so that it automatically corrects the
4670 pathname cleanups performed by make -M, so I don't have to fix them up
4673 Fixed the d_loaddump test case to be more robust, and not depend on
4676 Removed debugfs's dependence on pread(), which was accidentally
4677 intrudced in e2fsprogs 1.20
4679 Fixed a performance bug in the libext2fs's icount routine; the size
4680 estimate of the icount array was incorrectly being calculated.
4682 Removed use of the badblocks compatibility functions in the e2fsprogs
4685 Added paranoia code which protects against strange cases where /etc
4686 isn't on the root filesystem, or if /etc/mtab doesn't exist.
4688 The header file ext2_types.h is now installed.
4690 Autoconf is used to determine when we are on big-endian machines,
4691 instead of doing run-time tests, to save a few bytes of code.
4693 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4694 functions are no longer inline functions, which saves space and
4695 doesn't really cost any real performance.
4697 The ext2fs library no longer depends on the e2p library. (What need
4698 there was of it --- namely, fsetflags, was coded in-line).
4700 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4701 when the user is stupid and tries compiling the package using "make
4704 Miscellaneous 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.
4712 E2fsprogs 1.20 (May 20, 2001)
4713 =============================
4715 Add support for replaying the ext3 journal purely in user mode,
4716 including handling the orphaned inode list. Used code contributed by
4717 Andreas Dilger, with bug fixes and the orphaned inode handling done
4720 The mke2fs and tune2fs programs can create or modify a filesystem to
4721 include an ext3 journal. Tune2fs also can be used to remove an ext3
4722 journal from a filesystem.
4724 E2fsck will now check for the existence of a linked list of orphan
4725 inodes in the superblock, and clear those inodes before starting the
4726 rest of the filesystem check (but after the journal playback).
4728 E2fsck now validates the file descriptor passed to the -C option,
4729 which saves against the completion bar getting written to an
4730 unexpected location, such as the disk being checked. (Debian
4731 bug/wishlist #55220)
4733 E2fsck will now bump the filesystem revision number from zero to one
4734 if any of the compatibility bits are set.
4736 Fixed a bug where a badly corrupted directory on a big endian system
4737 could cause e2fsck to die with a bus error. The
4738 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4739 the ext2 library now does alignment sanity checks on the rec_len field
4740 of the directory entry before using it.
4742 The ext2 library has been enhanced to make tune2fs safe to run on
4743 mounted filesystems. (Users could usually get away with using tune2fs
4744 on mounted filesystems before, but with the advent of ext3 and
4745 journaling, it became important to make tune2fs was *really* safe for
4746 use even when the filesystem being modified is mounted.) E2label is
4747 now implemented by tune2fs using an argv[0] dispatch, so that e2label
4748 is also now safe for use on mounted filesystems.
4750 Added a new program, e2image, which creates a backup of critical ext2
4751 filesystem data structures. The generated image file can be examined
4752 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4753 the image file to help recover very badly damaged filesystems.
4755 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4756 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4757 large file when deciding whether or not the filesystem has large files.
4759 Fixed lsattr and chattr so that they work correctly on large files.
4760 (Fixes Debian bug #72690.)
4762 Removed limitation in get_device_size() which imposed a one terrabyte
4763 filesystem limitation. (Most 2.2 kernels still have a signed int
4764 problem which cause 1 TB block device limitation. Fortunately, the
4765 kernel patches to fix this are much easier than fixing the 2TB
4766 limitation in the kernel. :-)
4768 A max_mount_count of zero is now treated as if no mount count were
4769 set. (Previously, no mount count was indicated by using -1, and a
4770 mount count of zero caused e2fsck to always be run.)
4772 Mke2fs supports two new filesystem types largefile and largefile4.
4774 Mke2fs now adds some randomness in s_max_mount_count so that multiple
4775 filesystems won't be all checked at the same time under normal
4778 Fixed bug in the progress bar printing code which could cause e2fsck
4779 to core dump on an illegal filesystem.
4781 Fixed bug in fsck which could allow more than one instance of e2fsck
4782 to be printing a progress bar. (Debian bug #65267)
4784 Fsck using a UUID or a LABEL specifier will work even if devfs is
4785 compiled into the kernel and not mounted. If the pathnames in
4786 /proc/partitions are incorrect, fsck will search /dev for the correct
4787 device (using the new ext2fs_find_block_device library function).
4788 Fsck now also checks the RAID devices first so that they are properly
4789 found when they are in use. Support has also been added to support
4790 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4792 Fixed a bug in fsck which caused it not deal properly with 16
4793 byte long filesystem labels.
4795 Fsck's -t option has been made a lot more flexible. The semantics for
4796 what happens if a comma-separated list to fsck has been regularized,
4797 and it is now possible to filter what filesystems will get checked
4798 based what is in the filesystem's fstab entry's option field. (Debian
4801 The dumpe2fs program can now print out the group description
4802 information in hex, and also prints the location of the superblock and
4803 block group descriptor for those block groups that have them.
4805 Mke2fs now clears the ext2 superblock before it starts creating a
4806 filesystem, so that the superblock magic number is only written if the
4807 filesystem creation process successfully completes.
4809 The debugfs program's stat command now pretty-prints the blocks used
4810 by an inode so that it's more compact and informative.
4812 The debugfs stats command now uses the same libe2p code (which is used
4813 by dumpe2fs) to print the superblock header information. This is more
4814 complete, and it avoids a bit of code duplication.
4816 Added a new debugfs command, set_super_value (ssv) which allows the
4817 user to set arbitrary superblock fields.
4819 Debugfs was extended to support inode numbers in hex (by prefixing
4820 them with 0x), and so that modify_inode can set the inode generation
4821 number. Also, there is now a new function command called logdump
4822 which will dump an ext3 journal.
4824 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4827 Debugfs's dump command now stops immediately upon reporting a disk
4828 read error. (Fixed a bug in ext2fs_file_read library routine which
4829 caused debugfs not to stop.) (Debian bug #79163)
4831 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4832 checked before /etc/mtab is used, since /proc/mounts is more likely to
4835 Added portability fixes for Solaris and Linux/ia64.
4837 Various manual pages were clarified and cleaned up. (Fixed debian
4838 bugs #63442, #67446, and #87216)
4844 The e2fsck message printer now supports %Iu and %Ig, which will print
4845 out the inode's user and group owners, respectively.
4847 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4848 that no longer dependent on the system having the correct version of
4849 the kernel header files.
4851 Added a new function to libext2, ext2fs_find_block_device(), which
4852 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4853 device given its device number.
4855 Added a new function to libext2, ext2fs_sync_device, which centralizes
4856 all of the places which might try to use the BLKFLSBUF or FDFLUSH
4857 ioctls (and usually failing to define them since the system header
4858 files don't usually do this for us, and we're trying to avoid usage of
4859 kernel include files now).
4861 Added new utility programs in tests/progs: random_exercise and
4862 hold_inode. They aren't built by default; they're useful for
4863 exercising ext3 filesystem code.
4865 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4866 the filesystem close functions to only update the superblock, and to
4867 not touch the block group descriptors. Needed by tune2fs when
4868 modifying a mounted filesystem.
4870 Got rid of struct ext2fs_sb and replaced it with the standard struct
4871 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
4872 source (but not binary) compatibility of some users of the ext2
4873 library. Those applications should just simply do a global search and
4874 replace of struct ext2fs_sb with struct ext2_super_block, and include
4875 the new header file <ext2fs/ext2_fs.h> which defines it.
4877 The ino_t type has been renamed ext2_ino_t to protect applications
4878 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4879 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
4880 unexpected ABI change.
4882 The Makefiles have been reworked so that "make check" can be run from
4883 the top-level Makefile.
4885 Fix general gcc -Wall complaints and removed dead code.
4887 Remove use of NOARGS, because we assume everyone does ANSI C these
4890 Added build-rpm script from sct.
4892 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
4895 New function ext2fs_flush_icache which must be called if the
4896 application program modifies the inode table blocks without going
4897 through ext2fs_write_inode() interface.
4899 New ext2fs_check_mount_point() function, which will return the mount
4900 point of a device if mounted.
4902 The io_channel abstraction now has an optional interface,
4903 io_channel_write_range, which allows specific byte ranges to be
4906 The unix_io IO channel now supports write-through caching, so that
4907 journal creation is more efficient.
4909 Added x86 assembly language routines to support byte swapping, to
4910 reduce executable size.
4912 Fixed bug in the utility program subst so that it's possible to
4913 replace a substitution variable with a zero-length string.
4915 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4916 slipped into some of the problem number.
4918 E2fsprogs 1.19 (July 13, 2000)
4919 ==============================
4921 Release the resize2fs program since the timeout before it could
4922 be released under the GPL has finally expired.
4924 Add experimental support needed for the ext2 compression patches.
4925 This requires compiling e2fsprogs with the --enable-compression flag
4926 to the configure script.
4928 Added ext3 journalling support. E2fsck will run the journal (if
4929 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
4930 installed as a symlink to e2fsck. Fsck has been taught about ext3,
4931 and treats it the same as ext2 in terms of the progress bar logic.
4932 Dumpe2fs will display the superblock journaling information if the
4933 filesystem has a journal. The ext2 library will now permit opening an
4934 ext3 filesystem with the recovery flag set. This is necessary for
4935 on-line dump's to work correctly, but there may be issues with this
4936 working well since ext3 is much less agressive about syncing blocks to
4937 the filesystem, since they're safe on the journal.
4939 Tune2fs and e2fsck have been changed to allow the mount_count check to
4940 be disabled by setting max_mount_count to -1. (This was already
4941 supported by the kernel.)
4943 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4944 are used for ext3 as well.
4946 Added internationalization support for e2fsprogs; must be enabled
4947 by passing --enable-nls to configure.
4949 Always use the provided ext2fs header files to insulate ourselves from
4950 kernel version changes. Which include files are used by e2fsprogs
4951 have also been cleaned up to improve portability.
4953 Limit the number of times that e2fsck updates the progress bar so that
4954 people who are booting using a 9600 baud console don't get swampped by
4957 Improved the loop detection algorithm in e2sck's pass #3 so that it is
4958 much, much faster for large filesystems with a large number of
4961 The memory footprint for e2fsck is now slightly smaller than before.
4963 E2fsck now checks if special devices have a non-zero size, and offers
4964 to clear the size field if it finds such an inode.
4966 E2fsck now checks if special devices have the append-only flag set,
4967 and offers to clear the inode.
4969 E2fsck now properly handles some "should never fail" cases during a
4970 bitmap copy in pass5.
4972 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4974 E2fsck now calculates the correct location of the backup superblock in
4975 the case of filesystem blocksizes > 1k.
4977 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4978 which normally didn't cause problems under most filesystem parameters,
4979 but could cause a valid superblock to be rejected in extreme cases.
4980 Other checks for validating superblock values were made more
4983 Added non-destructive write testing to the badblocks program, courtesy
4984 of David Beattie. The badblocks also now has an option to input the
4985 current set of bad blocks, so that known bad blocks are skipped to
4986 speed up the badblocks test. There is also a persistent rescan
4987 feature which causes badblocks to run until it has completed some
4988 number of passes without discovering any new bad blocks.
4990 Badblocks now checks to see if the device is mounted and refuses to do
4991 the tests involving writing to the device if it is mounted. Also,
4992 badblocks now allows the number of blocks to be checked to be
4993 defaulted to the size of the partition.
4995 Fixed a bug in fsck which didn't allow non-root users to be able to
4996 check filesystems if there were any LABEL= or UUID= entries in
4999 The Hurd doesn't support the filetype filesystem feature. The mke2fs
5000 program now makes sure that for the Hurd, the filestype feature is
5001 turned off. E2fsck will check to see if the filetype feature is
5002 turned on for Hurd filesystems, and offer to turn off the feature.
5004 Mke2fs now has a safety check to make sure the number of blocks do not
5005 exceed 32 bits even on a 64 bit platform.
5007 Really fixed a bug in fsck to allow "fsck -As" to run interactive
5008 fsck's. (For those people who like to do interactive fsck's in the
5011 Debugfs has a few new features: the rdump command, which will do a
5012 recursive dump of a directory and all of its contents, and the lcd
5013 command which does a local chdir (much like the ftp command of the
5014 same name). In addition, the debugfs program and the open_filesystem
5015 command now takes three new options: -b and -s, which allows the
5016 blocksize and superblock location to be specified, and the -c option
5017 which is used in catastrophic situations where the block group
5018 descriptors are corrupt. If the -c option is specified, debugfs will
5019 skip trying to read in the block and inode bitmaps.
5021 Debufs's lsdel command was fixed to handle bad blocks in the inode
5024 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
5027 General improvements in error messages
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".
5034 - Fsck now prints more self-explanatory message if an invalid UUID=
5035 or LABEL= specification is passed to it.
5037 UUID library changed to use the LGPL.
5039 Fixed a bug in the UUID library where very rapid calls to the
5040 time-based UUID generator could cause duplicate UUID's to be returned.
5041 This was not a problem for e2fsprogs, but it could be a problem for
5042 other users of the library.
5044 Make the UUID library more robust in the face of missing or an
5045 improper /dev/urandom or /dev/random files.
5047 Added some random portability fixes for Solaris.
5049 Some minor man page updates.
5051 Fixed a memory leak in the ss library.
5057 We now try to use lseek64 and open64 from the LFS if possible.
5059 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5062 The mark and unmark bitmap functions now return the previous state of
5063 the bit that was being changed, which is useful for some speed
5066 The following functions have been added to enhance the badblocks list
5067 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5068 ext2fs_badblocks_equal.
5070 The ext2 header files now have the latest journalling fields to the
5073 The ext2fs_mkdir function in libext2fs now properly backs out of error
5074 conditions robustly.
5076 Cleaned 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.
5081 Fix test_script so that it works correctly when compiling in the
5084 The random UUID generation routine has been made slightly better in
5085 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5086 is still not recommended if /dev/random doesn't exist, however; it's
5087 better to use the time/ethernet MAC address UUID in this case.)
5089 Clean up the build process so it's more friendly in case of missing
5092 The ext2fs header file can now be #include'd into C++ programs.
5094 The e2p.h header file is now installed.
5096 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5100 E2fsprogs 1.18 (November 10, 1999)
5101 ==================================
5103 Fix 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
5105 has to restart pass 1 processing. E2fsck now closes the filesystem
5106 before freeing a large number of its data structures, so in the case
5107 of future memory faults, at least the fixed filesystem will be fully
5110 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5111 imagic inode, it will offer to clear the imagic flag.
5113 E2fsck will now offer to clear the immutable flag on special files
5114 (device/socket/fifos) when running it in non-preen mode.
5116 E2fsck will now set the filetype when creating /lost+found, and when
5117 connected orphaned inodes to /lost+found.
5119 Debugfs's ncheck and icheck commands now handles the case where there
5120 are bad blocks in the inode table without bombing out.
5122 The badblocks list processing code has been made more efficiently for
5123 appending a large number of (ordered) badblocks to the badblocks list.
5125 Some minor man page updates.
5127 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5128 mode, but some people like to do this in boot scripts for silly reasons).
5133 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5134 with the problem code convention.
5136 The badblocks list regression test program has been updated to work
5137 with previously made API name changes.
5139 The ext2fs_free() command now uses the new badblocks API to avoid
5140 using the compatibility layer.
5142 Added new regression test cases; the run_e2fsck test script now
5143 supports the ability for a test case to run a prepratory command
5144 before running e2fsck.
5146 E2fsprogs 1.17 (October 26, 1999)
5147 =================================
5149 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5152 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5153 thus potentially causing problems if a binary UUID contained a NULL
5156 E2fsck now uses stricter checks for directory entries in pass 2:
5157 zero-length filenames are not allowed; neither are 8 byte long
5160 The debugfs "dirty" command now clears the filesystem valid bit.
5161 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5162 bit in the in-core superblock image. The new functionality is more
5163 what the user expects, and is more useful.)
5165 Added a debugging hook to test parallel fsck; if the environment
5166 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5167 will be checked in parallel when they normally would not be.
5172 Fixed some #ifdef's for compilation under the Hurd OS.
5174 Fixed minor W2K compatibility problems.
5176 Fixed some miscellaneous GCC warnings.
5179 E2fsprogs 1.16 (October 22, 1999)
5180 =================================
5182 Fixed a race condition bug in fsck; when printing a progress bar, if
5183 checking multiple filesystems in parallel, it was possible for fsck to
5184 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5185 handler, which would cause it to terminate with a signal 10.
5187 E2fsck now properly handles filesystems that have the
5188 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5189 filesystem into using or not using FILETYPE feature.
5191 E2fsck now properly handles filesystems that have the IMAGIC feature
5192 turned on (this is used on Linux AFS servers).
5194 The mke2fs program now creates filesystems that have the filetype and
5195 sparse_superblock features enabled by default, unless it is run on a
5196 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5197 so there is now a new flag -O which allows the user to specify with
5198 which features she would like to create the filesystem; "mke2fs -O
5199 none" will create a filesystsem compatible with 2.0 kernels.
5201 The tune2fs program now has a -O option which allows the user to set
5202 and reset "safe" filesystem features. Currently, the only ones which
5203 allows to be modified are the filetype and sparse_superblock features.
5204 Note setting or clearing either feature will require running e2fsck on
5205 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5206 requires that there is enough free space on the filesystem for the
5207 extra superblocks which will be created by e2fsck.)
5209 Debugfs can now set and print filesystem features in the superblock
5210 using the "features" command. Dumpe2fs will print out the complete
5211 set of features when listing the superblock.
5213 Dumpe2fs has new options -f (force) and -h (header-only).
5215 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5216 message to come up. This could happen when decrementing or
5217 incrementing a link count could result in an overflow.
5219 Fixed a bug in e2fsck where the block count on the lost+found
5220 directory would not be properly incremented when the directory was
5221 expanded to the point where an indirect block needed to be allocated.
5223 E2fsck now makes some additional sanity checks on the superblock to
5224 avoid crashing or giving a memory allocation error if some of the
5225 values in the superblock are unresonable (but the superblock otherwise
5228 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5229 require two passes to completely fix the filesystem. This happened if
5230 an inode claimed blocks that was part of the filesystem metadata
5231 (typically, when garbage was written into an inode table or indirect
5232 block, since this kind of filesystem corruption normally doesn't
5235 On the Alpha, glibc declares st_flags although it isn't actually used;
5236 the configure script was improved to detect this case so that
5237 e2fsprogs can avoid using the non-functional stat field.
5239 The manual pages were updated to use a more consistent formatting
5240 style consistent with standard Unix man pages. Mke2fs's man page
5241 added documentation for a few previously undocumented options.
5243 Fixed minor display bugs in tune2fs and mke2fs.
5248 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5250 Added features to parse and print feature strings into the e2p library.
5251 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5253 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5254 whose directory entries contain proper filetype information if the
5255 filesystem supports it.
5257 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5258 the directory entry filetype information. This is used to set the
5259 directory entry filetype information if the filesystem supports it.
5261 Fixed a bug in ext2fs_expand_dir() where the block count in a
5262 directory's inode would not be properly incremented when the directory
5263 was expanded to the point where an indirect block needed to be
5267 E2fsprogs 1.15 (July 18, 1999)
5268 ==============================
5270 Add configuration checks so that e2fsprogs will compile cleanly on
5271 Linux 2.3 kernels that have renamed i_version to i_generation.
5273 E2fsck now prints a progress/completion bar (and not just a simple
5274 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5275 signal. Fsck will automatically manage the (potentially muliple)
5276 e2fsck processes to print completion bars if it is given a -C option,
5277 with the right thing happening if multiple filesystems are being
5278 checked in parallel.
5280 Mke2fs now has better automatic hueristics to determine the filesystem
5281 parameters 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,
5283 which helps mke2fs do a better job selecting the filesystem parameters.
5285 Mke2fs now creates revision 1 filesystems by default, and with the
5286 sparse superblock feature enabled. The sparse superblock feature is
5287 not understood by Linux 2.0 kernels, so they will only allow read-only
5288 mounts of filesystems with this sparse superblocks.
5290 Fix bug where if /dev/null couldn't be opened (should never happen),
5291 e2fsck would hang in a tight loop.
5293 Make e2fsck handle the case where /lost+found isn't a directory.
5295 E2fsck now uses mallinfo if it exists to get accurate statistics about
5298 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5299 inode had any problems before connecting it to /lost+found.
5301 Add check to e2fsck so it makes sure that total number of inodes in
5302 the filesystem is a sane number.
5304 Fix fencepost error when clearing an the end of the block bitmap which
5305 caused the last block in the bitmap not to get cleared.
5307 Cleaned 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.
5315 Added a new command-line utility, uuidgen, which will create and print
5318 Make debugfs's icheck command more robust by checking to make sure an
5319 inode has valid blocks before interarting over the inode's blocks.
5321 UUID generation now uses a random-based scheme whenever possible to
5322 prevent potential privacy problems.
5324 Man pages for all of the UUID functions in the lirbary were added.
5326 Fixed bug in fsck so it won't coredump if a filesystem not in
5327 /etc/fstab is given to it.
5329 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5330 that most of the other mount utilities understands.
5332 Mke2fs will make a filesystem even if it appears mounted if the force
5335 Dumpe2fs has new command-line options which allow a filesystem expert
5336 to specify the superblock and blocksize when opening a filesystem.
5337 This is mainly useful when examining the remains of a toasted
5340 The badblocks program has been updated to display correctly on disks
5341 with large block numbers.
5343 The badblocks program no longer gives spurious errors when errors
5344 occur on non-block boundaries, which is common if the blocksize is
5347 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5348 MKE2FS_SYNC environment variable is set. This is to work around a VM
5349 bug in the 2.0 kernel. I've heard a report that a RAID user was able
5350 to trigger it even using a 2.2 kernel, but hopefully it will not be
5351 needed for most Linux 2.2 users.
5353 Fixed miscellaneous documentation and man pages.
5358 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5359 in e2fsck's pass1.c really should have been static.
5361 The return value of the uuid_compare() function was changed to make it
5362 match with the convetions used by strcmp, memcmp, and Paul Leach's
5363 UUID sample document.
5365 The "make depend" process has now been made more automated; it now
5366 automatically word-wraps the dependencies, and only replaces source
5367 Makefile.in if there has been a change in the dependencies. Also, a
5368 top-level "make depend" now recurses through all the subdirectories
5371 The Makefile in .../util has been changed so that subst is built using
5372 the native C compiler during a cross-compilation, since the subst
5373 program is only used during the build process. Also add an explicit
5374 rule to build util/subst by cd'ing to the correct directory and
5377 The man directories are defined in terms mandir, so that the configure
5378 script can override the location of the manual pages.
5380 The config files have been updated to recognize new machine types for
5381 both the i386 and alpha families.
5383 Fsck has been modified so that it will accurately create an
5384 fsck_instance even when the noexecute flag is set. This allows for
5385 accurate debugging of the fsck pass structure. Also, when the verbose
5386 flag is given twice, fsck will print debugging information about when
5387 fsck is waiting for jobs to finish.
5390 E2fsprogs 1.14 (January 9, 1999)
5391 ================================
5393 Fix the fstab parsing code so that it can handle blank lines and
5394 comment characters. Also, missing pass numbers need to be treated as
5397 Fixed a bug in e2fsck where under some circumstances (when e2fsck
5398 needs to restart processing after fixing an egregious inconsistency)
5399 it would try to access already freed memory.
5401 E2fsck now prints non-printable characters in directory entries and
5402 pathnames using '^' and 'M-' notation.
5404 Fixed chattr so that it will ignore symbolic links when doing
5405 recursive descent traversals. For both chattr and lsattr, no longer
5406 print the version string unless the -V option is given.
5408 Allow the system administrator to directly specify the number of
5409 inodes desired in the filesystem, for some special cases where this is
5412 Fix portability problems so that e2fsprogs can be compiled under Linux
5413 1.2 systems and Solaris systems.
5415 Update the config.guess file with a more recent version that will
5416 identify newer Linux platforms.
5421 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5422 an inode number of zero is passed to them.
5424 E2fsprogs 1.13 (December 15, 1998)
5425 ==================================
5427 Fixed a bug in debugfs where an error messages weren't getting printed
5428 when the ext2 library routines to read inodes returned errors in the
5429 stat, cmri and rm commands.
5431 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5432 provided, it won't create an inode table smaller than the minimum
5433 number of inodes required for a proper ext2 filesystem.
5435 Fsck now parses the /etc/fstab file directly (instead of using
5436 getmntent()), so that it can distinguish between a missing pass number
5437 field and pass number field of zero. This caused problems for
5438 diskless workstations where all of the filesystems in /etc/fstab have
5439 an explicit pass number of zero, and fsck could not distinguish this
5440 from a /etc/fstab file with missing pass numbers.
5442 E2fsck will create a /lost+found directory if there isn't one in the
5443 filesystem, since it's safer to create the lost+found directory before
5446 Fixed e2fsck so that it would detect bogus immutable inodes which
5447 happen to be sockets and FIFO files, and offer to clear them.
5449 If a filesystem has multiple reasons why it needs to be checked, and
5450 one of the reasons is that it is uncleanly mounted, e2fsck will print
5451 that as the reason why the filesystem is being checked.
5453 Cleaned up the output routines of mke2fs so that it doesn't overflow
5454 an 80 column display when formating really big filesystems.
5456 Added a sanity check to e2fsck to make sure that file descriptors 0,
5457 1, 2 are open before opening the hard disk. This avoids a problem
5458 where a broken program might exec e2fsck with those file descriptors
5459 closed, which would cause disastrous results if the kernel returns a
5460 file descriptor for the block device which is also used by FILE *
5463 Fixed up the e2fsck progress reporting functions so that the values
5464 reliably reach 100% at the completion of all of the e2fsck passes.
5466 Fixed minor documentation bugs in man pages and usage messages.
5471 Fixed a number of lint warnings in the ext2fs library and potential
5472 portability problems from other OS's header files that might define
5473 CPP macros for names like "max" and "min".
5475 ext2fs_badblocks_list_add() has been made more efficient when it needs
5476 to grow the bad blocks list.
5478 Fixed a bug in e2fsck which caused it to dereference a freed pointer
5479 just before exiting.
5481 Fixed the substition process for generating the mk_cmds and compile_et
5482 scripts so that they will work outside of the build tree.
5484 Add sanity check to e2fsck so that if an internal routine
5485 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5486 and causing a core dump. This should never happen, but...
5488 E2fsprogs 1.12 (July 9, 1998)
5489 ==================================
5491 E2fsprogs now works with glibc (at least with the version shipped wtih
5492 RedHat 5.0). The ext2fs_llseek() function should now work even with
5493 i386 ELF shared libraries and if llseek() is not present. We also
5494 explicitly 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
5496 complaints about libc developers don't understand the concept of
5497 compatibility with previous versions of libc.)
5499 The ext2fs library now writes out the block group number in each of
5500 the superblock copies. This makes it easier to automatically
5501 determine the starting block group of the filesystem when the block
5502 group information is trashed.
5504 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5505 which means that e2fsprogs will ignore the high 8 bits of the
5506 directory entry's name_len field, so that it can be used for other
5509 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5510 E2fsprogs will now support filesystems with 64-bit sized files.
5512 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5514 Added new program "e2label", contributed by Andries Brouwer. E2label
5515 provides an easy-to-use interface to modify the filesystem label.
5517 Fixed bug so that lsattr -v works instead of producing a core dump.
5519 Fixed a minor bug in mke2fs so that all groups with bad superblock
5520 backup blocks are printed (not just the first one).
5522 Mke2fs will check the size of the device, and if the user specifies a
5523 filesystem size larger than the apparent size of the device it will
5524 print a warning message and ask if the user wants to proceed.
5526 E2fsck has a new option -C, which sends completion information to the
5527 specified file descriptor. For the most part, this is intended for
5528 programs to use, although -C 0 will print a spinning character to the
5529 stdout device, which may be useful for users who want to see something
5530 happening while e2fsck goes about its business.
5532 Fixed a bug in e2fsck which could cause a core dump when it needs to
5533 expand the /lost+found directory, and sometimes the bitmaps haven't
5534 been merged in. Also fixed a related bug where ext2fs_write_dir_block
5535 was used to write out a non-directory block. (Which would be bad on a
5536 non-Intel platform with byte swapping going on.)
5538 Fixed bug in e2fsck where it would print a "programming error" message
5539 instead of correctly identifying where a bad block was in used when
5540 the bad block was in a non-primary superblock or block group
5541 descriptor. Also fixed a related bug when sparse superblocks are in
5542 use and there is a bad block where a superblock or block group
5543 descriptor would have been in a group that doesn't include a
5546 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5547 the block group descriptor table is corrupt, it was possible to try to
5548 allocate a huge array, fail, and then abort e2fsck.
5549 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5550 and subsitutes reasonable values if the descriptors are obviously bogus.
5552 If e2fsck finds a device file which has the immutable flag set and the
5553 i_blocks beyond the normal device number are non-zero, e2fsck will
5554 offer to remove it, since it's probably caused by garbage in the inode
5557 When opening a filesystem, e2fsck specially checks for the EROFS error
5558 code, and prints a specific error message to the user which is more
5561 If the filesystem revision is too high, change the e2fsck to print
5562 that this is either because e2fsck is out of date, or because the
5563 superblock is corrupt.
5565 E2fsck now checks for directories that have duplicate '.' and '..'
5566 entries, and fixes this corruption.
5568 E2fsck no longer forces a sync of the filesystem (with attendant sleep
5569 calls) at all times. The ext2fs_flush() function now performs a sync
5570 only if it needed to write data blocks to disk.
5572 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5573 certain errors would not be properly reported.
5575 Updated and expanded a few points in the man pages which users
5576 complained wheren't explicit enough.
5578 Added special case byte-swapping code if compiling on the PowerPC, to
5579 accomodate the strange big-endian variant of the ext2 filesystem that
5580 was previously used on the PowerPC port.
5586 Removed C++ keywords from the ext2fs libraries so that it could be
5589 E2fsck's internal organization has now been massively reorganized so
5590 that pass*.c don't have any printf statements. Instead, all problems
5591 are reported through the fix_problem() abstraction interface. E2fsck
5592 has also been revamped so that it can be called as a library from a
5595 Added new fileio primitives in libext2fs for reading and writing
5596 files on an unmounted ext2 filesystem. This interface is now used by
5599 Added a new libext2fs function for mapping logical block numbers of
5600 a file to a physical block number.
5602 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5603 a block, zeros it, and updates the filesystem accounting records
5606 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5607 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5609 The libext2fs functions now use a set of memory allocation wrapper
5610 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5611 instead of malloc, free, and resize. This makes it easier for us to
5612 be ported to strange environments where malloc, et. al. aren't
5613 necessarily available.
5615 Change the libext2fs fucntion to return ext2-specific error codes
5616 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5617 and depending on the existence of system error codes (such as EEXIST
5620 Renamed io.h to ext2_io.h to avoid collision with other OS's header
5623 Add protection against ext2_io.h and ext2fs.h being included multiple
5626 The types used for memory lengths, etc. have been made more portable.
5627 In generla, the code has been made 16-bit safe. Added Mark
5628 Habersack's contributed DOS disk i/o routines.
5630 Miscellaneous portability fixes, including not depending on char's
5633 The io_channel structure has a new element, app_data, which is
5634 initialized by the ext2fs routines to contain a copy of the filesystem
5637 ext2fs_check_directory()'s callback function may now return the error
5638 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5639 really do the checking, despite the presence of the callback function.
5642 E2fsprosg 1.11 (June 17, 1997)
5643 ==============================
5645 Fixed e2fsck to detect (previously ignored) conflicts between the
5646 superblock or block group descriptors and block bitmaps, inode
5647 bitmaps, and inode tables.
5649 Fixed bug in e2fsck so that when the message printed out when a block
5650 or inode bitmap conflicts with other data, it has the correct group
5653 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5654 to badblocks. This meant that not all of the filesystem was being
5655 tested for bad blocks!
5657 Fixed an array boundary overrun case which cropped up in
5658 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5661 Adjusted the number of columns printed by mke2fs when displaying the
5662 superblock backups to avoid running over 80 columns when making a
5663 really big filesystem.
5665 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5666 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5667 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5672 Fixed install rule in lib/ss so that ss_err.h is actually getting
5675 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5676 bassed back to the caller.
5678 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5679 setting the current inode number (which meant this function wasn't
5682 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5683 blocks in the bitmap when increasing the size of the bitmap.
5685 Changed the initial number of blocks allocated by ext2fs_init_dblist()
5686 to be more realistic.
5688 Added a new function ext2fs_allocate_group_table, which sets up the
5689 group descriptor information (and allocates inode and block bitmaps,
5690 and inode tables for a particular group). The function was created by
5691 factoring out code form ext2fs_allocate_tables().
5693 Added a new function ext2fs_move_blocks which takes a bitmap of the
5694 blocks to be moved, and moves them to another location on the
5697 Make the unix_io channel's io_channel_flush implementation calls sync()
5698 to to flush the kernel buffers to disk.
5700 Added a new function ext2fs_dblist_count returns the number of
5701 directory blocks in dblist.
5704 E2fsprogs 1.10 (April 24, 1997)
5705 ===============================
5707 Mke2fs once again defaults to creating revision #0 filesystems, since
5708 people were complaining about breaking compatibility with 1.2 kernels.
5709 Warning messages were added to the mke2fs and tune2fs man pages that
5710 the sparse superblock option isn't supported by most kernels yet (1.2
5711 and 2.0 both don't support parse superblocks.)
5713 Added new flag to mke2fs, -R <raid options>, which allows the user to
5714 tell mke2fs about the RAID configuration of the filesystem. Currently
5715 the only supported raid option is "stride" which specifies the width
5718 Fixed bug in e2fsck where pass1b would bomb out if there were any
5719 blocks marked bad in the inode table.
5721 Fixed rare bug in mke2fs where if the user had a very unlucky number
5722 of blocks in a filesystem (probability less than .002) the resulting
5723 filesystem would be corrupt in the last block group.
5725 Fixed bug where if e2fsck tried to allocate a block to fix a
5726 filesystem corruption problem and the filesystem had no free blocks,
5727 ext2fs_new_block() would loop forever.
5729 The configure script now checks explicitly to see if "-static" works,
5730 since that can't be assumed to be true --- RedHat doesn't install
5731 libc-static by default.
5733 Fixed bug in libext2's block iterator functions where under some
5734 cirmcustances, file with holes would cause the bcount parameter to the
5735 callback function to be incorrect. This bug didn't affect any of
5736 e2fsprogs programs, but it was discovered by Paul Mackerras, the
5737 author of the PPC boot loader.
5739 Removed use of static variables to store the inode cache in libext2fs.
5740 This caused problems if more than one filesystem was accessed via
5741 libext2fs (static variables in libraries are generally a bad idea).
5742 Again, this didn't affect e2fsprogs programs, but it was discovered by
5745 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5746 will compile cleanly with 1.2.13 kernels (even with a.out shared
5752 Added new functions to duplicate an ext2 filesystem handle, and its
5753 associated substructure. New functions: ext2fs_dup_handle(),
5754 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5755 Other structures, such as the io_channel and the inode_cache, now have
5756 a ref count so that they only get freed when they are no longer used
5757 by any filesystem handle. (These functions were added as part of the
5758 development effort for an ext2 resizer).
5760 E2fsprogs 1.09 (April 14, 1997)
5761 ===============================
5763 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5764 accidentally introduced in the 1.08 release. The overhead calculation
5765 was accidentally removed, which caused ext2fs_initialize() to not
5766 notice when the filesystem size needed to be adjusted down because
5767 there wasn't enough space in the last block group.
5769 Fixed bug in version parsing library routine; it was always parsing
5770 the library version string, instead of using the passed-in string.
5772 Clarified chattr man page.
5774 E2fsprogs 1.08 (April 10, 1997)
5775 ===============================
5777 E2fsck 1.07 was very slow when checking very large filesystems with a
5778 lot of files that had hard links (i.e., news spools). This was fixed
5779 by seriously revamping the icount abstraction. Added a formal test
5780 suite for the icount abstraction.
5782 Debugfs now has a "-l" option to the "ls" command, which lists the
5783 inode number, permissions, owner, group, size, and name of the files
5786 Fix a bug in e2fsck where when a directory had its blocks moved to
5787 another location during the pass 1b processing, the directory block
5788 list wasn't updated, so pass 2 wouldn't check (and correct) the
5789 correct directory block.
5791 E2fsck will now treat inodes which contain blocks which are claimed by
5792 the filesystem metadata by treating them as multiply claimed blocks.
5793 This way, the data in those blocks can be copied to a new block during
5794 the pass 1b--1d processing.
5796 E2fsck will attempt to determine the correct superblock number and
5797 display it in the diagnostic and warning messages if possible.
5799 Add support for a new (incompatible) feature, "sparse_super". This
5800 feature reduces the number of blocks which contain copies of backup
5801 superblocks and block group descriptors. (It is only an incompatible
5802 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5803 support a new -s option; e2fsck will recognize filesystems built with
5804 this feature turned on.
5806 E2fsck now checks the library to make sure is the correct version,
5807 using new library functions. (This helps to diagnose incorrectly
5808 installed e2fsprogs distributions.)
5810 Dumpe2fs now prints more information; its now prints the the
5811 filesystem revision number, the filesystem sparse_super feature (if
5812 present), the block ranges for each block group, and the offset from
5813 the beginning of the block group.
5815 Mke2fs now distributes the inode and block bitmap blok so that the
5816 won't be concentrated in one or two disks in RAID/striping setups.
5817 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5818 choose the largest blocks per group that be chosen. (For 2k blocks,
5819 you can have up to 16384 blocks/group; for 4k blocks, you can have up
5820 to 32768 blocks/group.) Previously mke2fs would not allow
5821 specification of more than 8192 blocks per group, even if you were
5822 using a 2k or 4k block group.
5827 Added a new function ext2fs_create_icount2() which takes a "hint"
5828 argument. This hint argument presets the icount array with the list
5829 of inodes which actually need to be in the icount array. This really
5830 helps to speed up e2fsck.
5832 Added a new function ext2fs_icount_validate() which checks the rep
5833 invariant for the icount structure. This is used mostly for testing.
5835 The error mesasage given when a bad inode number is passed to
5836 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5837 EXT2FS_UNMARK_ERROR).
5839 Added a new function ext2fs_set_dir_block which sets the block of a
5840 dblist entry, given the directory inode and blockcnt.
5842 Added a new function ext2fs_get_library_version() which returns the
5843 current library version, and ext2fs_parse_version_string() which
5844 returns a version number based on a e2fsprogs version string.
5846 The icount functions will return EINVAL if the passed in inode number
5849 E2fsprogs 1.07 (March 9, 1997)
5850 ==============================
5852 E2fsck is now uses much less memory when checking really large
5853 filesystems (or rather, filesystems with a large number of inodes).
5854 Previously a filesystem with 1 million inodes required 4 megabytes of
5855 memory to store inode count statistics; that storage requirement has
5856 now been reduced to roughly half a megabyte.
5858 E2fsck can now properly deal with bad blocks appearing inside the
5859 inode table. Instead of trying to relocate the inode table (which
5860 often failed because there wasn't enough space), the inodes in the bad
5861 block are marked as in use.
5863 E2fsck will automatically try to use the backup superblocks if the
5864 primary superblocks have a bad magic number or have missing meta-data
5865 blocks (or meta-data blocks which are out of range).
5867 E2fsck's pass 3 has been made more efficient; most noticeable on
5868 filesystems with a very large number of directories.
5870 Completely revamped e2fsck's system of printing problem reports. It
5871 is now table driven, to make them more easily customizeable and
5872 extendable. Error messages which can be printed out during preen mode
5873 are now one line long.
5875 Fixed e2fsck's filesystem swapping code so that it won't try to swap
5876 fast symbolic links or deleted files.
5878 Fixed e2fsck core dumping when fixing a filesystem which has no
5879 directories (not even a root directory).
5881 Added a check to e2fsck to make sure that the length of every
5882 directory entry is a multiple of 4 (since the kernel complains if it
5885 Added a check to e2fsck to make sure that a directory entry isn't a
5886 link to the root directory, since that isn't allowed.
5888 Added a check to e2fsk to now make sure the '.' and '..' directory
5889 entries are null terminated, since the 2.0 kernel requires it.
5891 Added check to write_bitmaps() to make sure the superblock doesn't get
5892 trashed if the inode or block bitmap is marked as being block zero.
5894 Added checking of the new feature set fields in the superblock, to
5895 avoid dealing with new filesystem features that this package wasn't
5898 Fixed a fencepost error in ext2fs_new_block() which would occasionally
5899 try to allocate a block beyond the end of a filesystem.
5901 When the UUID library picks a random IEEE 802 address (because it
5902 can't find one from a network card), it sets the multicast bit, to
5903 avoid conflicting with a legitimate IEEE 802 address.
5905 Mke2fs now sets the root directory's owner to be the real uid of the
5906 user running mke2fs. If the real uid is non-zero, it also sets
5907 the group ownership of the root directory to be the real group-id of
5908 the user running mke2fs.
5910 Mke2fs now has more intelligent error checking when it is given a
5911 non-existent device.
5913 When badblocks is given the -vv option, it now updates the block that
5914 it is currently testing on every block.
5916 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5917 currently correctly if PATH wasn't already set.
5919 Shared libraries now built with dependencies. This allows the shared
5920 library files to be used with dlopen(); it also makes the transition
5921 to libc 6 easier, since ld.so can tell which libc a particular shared
5922 library expects to use.
5927 Added new abstraction (defined in dblist.c) for maintaining a list of
5928 blocks which belongs to directories. This is used in e2fsck and other
5929 programs which need to iterate over all directories.
5931 Added new functions which test to see if a contiguous range of blocks
5932 (or inodes) are available. (ext2fs_*_bitmap_range).
5934 Added new function (ext2_inode_has_valid_blocks) which returns true if
5935 an inode has valid blocks. (moved from e2fsck code).
5937 Added new function (ext2fs_allocate_tables) which allocates the
5938 meta-data blocks as part of initializing a filesystem. (moved from
5941 Added a new I/O manager for testing purposes. It will either allow a
5942 program to intercept I/O requests, or print debugging messages to
5943 trace the activity of a program using the I/O manager.
5945 The badblocks_list functions now store the bad blocks in a sorted
5946 order, and use a binary search to speed up badblocks_list_test.
5948 The inode scan function ext2fs_get_next_inode() may now return a soft
5949 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5950 those cases where part of an inode table is missing or there is a bad
5951 block in the inode table.
5953 Added a new function (ext2fs_block_iterate2) which adds new arguments to
5954 the callback function to return a pointer (block and offset) to the
5955 reference of the block.
5957 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5958 application to jump to a particular block group while doing an inode
5961 The badblocks list functions were renamed from badblocks_* to
5962 ext2fs_badblocks_*. Backwards compatibility functions are available
5963 for now, but programs should be modified to use the new interface.
5965 Some of the library functions were reorganized into separate files to
5966 reduce the size of some programs which statically link against the
5969 Put in some miscellaneous fixes for the Alpha platform.
5972 E2fsprogs 1.06 (October 7, 1996)
5973 ================================
5975 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5976 smash the backup copies in ext2fs_close(). (The problem was that when
5977 e2fsck -p discovered the problem, while it was closing the filesystem
5978 and exiting, it was also blowing away the backup superblocks on the
5979 disk, which was less than friendly.) We now make it the case that we
5980 only write out the backup superblock and the back block descriptors if
5981 the filesystem is completely free from problems.
5983 Fixed a bug in block_interate in the lib/ext2fs library which caused
5984 e2fsck to fail on GNU Hurd-created filesystems.
5986 Add support for Linux/FT's bootloader, which actually uses
5987 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5990 Add support for the "A" (no atime update) attribute. (Note: this
5991 attribute is not yet in production kernels.)
5993 The test suite is not automatically run when doing a "make all" from
5994 the top level directory. Users should manually run "make check" if
5995 they wish to run the test suite.
5997 Upon a preenhalt(), make the printed message more explicit that
5998 running e2fsck "MANAULLY" means without the -p or -a options.
6000 In e2fsck, if a disconnected inode is zero-length, offer to clear it
6001 instead of offering to connect it to lost+found.
6003 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6004 e2fsck to be run over it, change e2fsck to explicitly display this
6007 For dumpe2fs and e2fsck, cause the -V option to print out which
6008 version of the ext2fs library is actually getting used. (This will
6009 help detect mismatches of using a 1.06 utility with a 1.05 library,
6015 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6016 the naming convention.
6018 In ext2fs_initialize(), make sure the description for the inode bitmap
6019 is correctly initialize.
6021 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6023 E2fsprogs 1.05 (September 7, 1996)
6024 ==================================
6026 Add support for new fields in the ext2 superblock --- volume name,
6027 volume UUID, and last mounted field. Dumpe2fs displays these fields,
6028 tune2fs and mke2fs allows you to set them. E2fsck will automatically
6029 generate a UUID for those volumes that don't have them.
6031 Put in support for e2fsck to recognize HURD specific ext2 features ---
6032 most notably, the translator block. The e2fsprogs tools will now use
6033 the creator_os field in the superblock to correctly handle different
6034 OS-specific variants of the ext2 filesystem.
6036 E2fsck now fixes inodes which have a the deletion time set, but which
6037 have a non-zero i_link_count field by offering to clear the deletion
6038 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6039 ext2 kernel behavior) and offered to unlink the file.
6041 If e2fsck sets the clean bit, but nothing else, set the exit code
6042 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6043 set the filesystem valid bit when it was previously cleared. :-) This
6044 was needed to make the HURD fsck driver happy.
6046 If the user refuses to attach an unattached inode, e2fsck will no
6047 longer set the inode's link count. Otherwise, the inode would end up
6048 getting marked as unused, which might cause loss of data later.
6050 Make the message issued by e2fsck when the superblock is corrupt less
6051 confusing for users. It now mentions that another reason for the
6052 "corrupt superblock" message might be that the partition might not be
6053 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6055 Make the libext2 library more robuest so that e2fsck won't coredump on
6056 an illegal superblock where the blocksize is zero. (f_crashdisk is
6059 By default, create filesystems where the default checkinterval is 6
6060 months (180 days). Linux servers can be robust enough that 20 reboots
6061 can be a long, long time.
6063 Added configure flag --enable-old-bitops, which forces the bitops to
6064 use the old (native) bitmask operations. By default on the sparc
6065 platform, the standard ext2 bit ordering is now used.
6067 Added a new feature to e2fsck to byte-swap filesystems; this can be
6068 used to convert old m68k filesystems to use the standard byte-order
6069 storage for the superblock, inodes, and directory blocks. This
6070 function is invoked by using the '-s' option to e2fsck.
6072 Debugfs's "dump" command has been enhanced so that it writes out the
6073 exact size of the file so that the nulls at the end of the file are
6074 eliminated. The command also accept a new "-p" option which will
6075 attempt preserve to preserve the ownernship, permissions, and
6076 file modification/access times.
6078 Debugfs has two new options, -f and -R. The -R option allows the user
6079 to execute a single debugfs command from the command line. The -f
6080 option allows the user to specify a "command file" containing debugfs
6081 commands which will get executed.
6083 Dumpe2fs now pretty prints the check interval, instead of just
6084 printing the check interval as a number of seconds.
6086 Fix bugs in debugfs: the params command when no filesystem is opened
6087 no longer causes a core dump. It is now possible to unlink a file
6088 when a pathame containing a '/' is specified.
6090 Tune2fs has a new -C option which sets the number of times the
6091 filesystem has been mounted.
6093 Fix the chattr '-v' option so that it actually works. Chattr was
6094 being buggy about the -v option parsing.
6099 The directory lib/uuid contains a set of library routines to generate
6100 DCE compatible UUIDs.
6102 Extended ext2fs_namei() to handle symbolic links. Added new function
6103 ext2fs_nami_follow() which will follow last symbolic link in the case
6104 where the pathname points to a sym link.
6106 The ext2fs_block_iterate function will now return the HURD translator
6107 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6108 iterator to return data blocks only. The ext2fs.h file now defines
6109 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6110 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6111 count field of the iterator callback function.
6113 The test script driver now takes an optional second argument, which is
6114 the test case to be run. This allows you to run a test case without
6115 needing to run the entire test suite.
6117 On 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
6121 Fixed miscellaneous HURD compilation issues with header file being
6122 included in the right order.
6124 Fixed debugfs so that it resets optind to zero, not one, since setting
6125 optind to zero is more correct.
6128 E2fsprogs 1.04 (May 16, 1996)
6129 =============================
6131 First "official" (1.03 was a limited release only) to support building
6132 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6135 This package includes a RPM specs file, that it can be built using the
6136 RedHat Package Manager.
6138 E2fsck now prints a hint that if there are lots of incorrectly located
6139 inode bitmaps, block bitmaps, and inode table blocks, the user might
6140 want to try using e2fsck -b 8193 first, to see if that fares any
6143 For ext2 filesystem written with the hurd, debugfs will now print out
6144 the translator field when printing an inode structure.
6146 Lots of miscellaneous linking/installation cleanups:
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
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.
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.
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.
6171 The ss include files are now installed correctly so they can
6172 actually be used by another package.
6174 If the profiling libraries are built, they are now installed on a
6175 "make install-libs".
6178 E2fsprogs 1.03 (March 27, 1996)
6179 ===============================
6181 Change the m68k bit numbering for bitmasks to match the bit numbering
6182 used by all other ext2 implementations. (This change was requested by
6183 the m68k kernel development team.)
6185 Support (in-development) filesystem format revision which supports
6186 (among other things) dynamically sized inodes.
6188 Fixed a bug in the ext2 library so that an intelligent error is
6189 returned if mke2fs is run with a ridiculously small number of blocks
6192 Fixed a bug in the ext2 library which required that the device be
6193 openable in read/write mode in order to determine its size. This
6194 caused e2fsck -n to require read/write access when it was not
6195 previously necessary.
6197 Fixed a bug in e2fsck which casued it to occasionally fail the test
6198 suite depending on which version of the floating point library it was
6201 Fixed a bug in e2fsck so that it now halts with a fatal error when
6202 certain superblock consistency checks fail. Previously it continued
6203 running e2fsck, with some potential confusing/damaging consequences.
6205 Added new flag to fsck which allows the root to be checked in parallel
6206 with other filesytems. This is not the safest thing in the world to
6207 do, but some system administrators really wanted it.
6209 Fixed -Wall flames in lib/ss.
6212 E2fsprogs 1.02 (January 16, 1996)
6213 =================================
6215 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6217 Change e2fsck to print statistics of how many non-contiguous files are
6218 on the system. Note that a file which is larger than 8k blocks, it is
6219 guaranteed to be non-contiguous.
6221 In mke2fs, print a warning message if a user tries to format a whole
6222 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6223 whole disk, the -F (force) option forces mke2fs to format a whole disk
6226 Fix a bug in fsck where in some cases it might start checking
6227 partitions in the next pass before it finishes checking partitions in
6228 the current pass. This still won't cause two partitions on the same
6229 disk will be checked, so it's rarely a problem in real life.
6231 Patch lsattr so that it won't hang when checking a named pipe.
6233 Minor compilation fixes:
6234 * Fix the order of libraries that were linked in debugfs.
6235 * Allow the sources to be compiled with -ansi turned on.
