1 E2fsprogs 1.41.13 (December 13, 2010)
2 =====================================
4 E2fsck now supports the extended option "-E journal_only", which
5 causes it to only do a journal replay. This is useful for scripts
6 that want to first replay the journal and then check to see if it
9 E2fsck will now support UUID= and LABEL= specifiers for the -j option
10 (which specifies where to find the external journal). (Addresses
13 E2fsck now has support for the problems/<problem code>/force_no
14 configuration option in e2fsck.conf, which forces a problem to not be
17 Dumpe2fs will now avoid printing large negative offsets for the bitmap
18 blocks and instead print a message which is a bit more helpful for
21 Mke2fs will now check the file system type (specified with the -t
22 option) to make sure it is defined in the mke2fs.conf file; if it is
23 not, it will print an error and abort. If the usage type (specified
24 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
25 warning but will continue. (Addresses Debian Bug #594609)
27 Clarified error message from resize2fs clarifying that on-line
28 shrinking is not supported at all. (Addresses Debian Bug #599786)
30 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
31 displayed. (Addresses Debian Bug #555456)
33 E2fsck will open the external journal in exclusive mode, to prevent
34 the journal from getting truncated while it is in use due to a user
35 accidentally trying to run e2fsck on a snapshotted file system volume.
36 (Addresses Debian Bug #587531)
38 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
41 The tune2fs program can now set the uninit_bg feature without
44 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
45 default mount options settings which were added in 2.6.35.
47 The e2fsck and dumpe2fs programs now support the new ext4 superblock
48 fields which track where and when the first and most recent file
49 system errors occurred. These fields are displayed by dumpe2fs and
50 cleared by e2fsck. These new superblock fields were added in 2.6.36.
52 Debugfs now uses a more concicse format for listing extents in its
53 stat command. This format also includes the interior extent tree
54 blocks, which previously was missing from stat's output for
57 Debugfs has a new option, -D, which will request Direct I/O access of
60 Mke2fs will skip initializing the inode table if a device supports
61 discard and the discard operation will result in zero'ed blocks.
63 Badblocks will now correctly backspace over UTF-8 characters when
64 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
65 Debian Bugs #583782 and #587834)
67 E2freefrag will now display the total number of free extents.
69 Resize2fs -P no longer requires a freshly checked filesystem before
70 printing the minimum resize size.
72 Fixed a floating point precision error in a binary tree search routine
73 that can lead to seg fault in e2fsck and resize2fs.
75 Fixed a bug in e2fsck where if both the original and backup superblock
76 are invalid in some way, e2fsck will fail going back to the original
77 superblock because it didn't close the backup superblock first, and
78 the exclusive open prevented the file system from being reopened.
80 Fixed a big in e2freefrag which caused getopt parsing to fail on
81 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
83 Clarified an mke2fs error message so a missed common in an -E option
84 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
85 results in a more understandable explanation to the user.
87 Mke2fs now displays the correct valid inode ratio range when
88 complaining about an invalid inode ratio specified by the user.
90 Mke2fs now understands the extended option "discard" and "nodiscard",
91 and the older option -K is deprecated. The default of whether
92 discards are enabled by default can be controled by the mke2fs.conf
95 Mke2fs's handling of logical and physical sector sizes has been
96 improved to reflect the fact that there will be some SSD's with 8k and
97 16k physical sectors arriving soon. Mke2fs will no longer force block
98 size to be the physical sector size, since there will be devices where
99 the physical sector size is larger than the system's page size, and
100 hence larger than the maximal supported block size. In addition, if
101 the minimal and optimal io size are not exported by the device, and
102 the physical sector size is larger than the block size, the physical
103 sector size will be used to set the Raid I/O optimization hints in the
106 E2fsck will now display a better, more specific error message when the
107 user enters a typo'ed device name, instead of blathering on about
108 alternate superblocks.
110 Fixed various Debian Packaging Issues
112 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
113 #589345, #591083; Addresses Launchpad Bug: #505719)
115 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
116 Polish, Swedish, and Vietnamese translations.
122 Fix a dependency definition for the static and profiled blkid
123 libraries which could cause compile failures in some configurations.
124 (Addresses Debian Bug: #604629)
126 Add support for Direct I/O in the Unix I/O access layer.
128 Fixed a memory leak in the Unix I/O layer when changing block sizes.
130 Fixed minor memory leaks in mke2fs.
132 Added a new function to the ext2fs library, ext2fs_get_memalign().
134 The tst_super_size test program will check to make sure the superblock
135 fields are correctly aligned and will print them out so they can be
136 manually checked for correctness.
138 Fixed some makefile dependencies for test programs in lib/ext2fs.
140 Reserved the feature flags and superblock fields needed for the Next3
143 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
144 EXT4_INCOMPAT_EA_INODE.
147 E2fsprogs 1.41.12 (May 17, 2010)
148 ================================
150 Mke2fs now gives a correct error message if the external journal
151 device is not found. (Addresses Red Hat Bug #572935)
153 Resize2fs -P will now refuse to print a minimum size if the file
154 system is not clean. Previously it would go ahead and print a minimum
155 size anyway, which might not be correct, leading to user confusion.
157 E2fsck now tests for extents that begin at physical block 0 and
158 rejects them as invalid. (Addresses Google Bug: #2573806)
160 Fixed a bug in e2fsck which could cause it to crash when trying to
161 remove an invalid extent and the block bitmaps hadn't yet been loaded.
162 (Addresses SourceForge Bug: #2971800)
164 E2fsck now will completely skip time-based checks if the system clock
165 looks insane or the option broken_system_clock is set in
168 E2fsck would previously report an i_blocks corruption for a 4T file
169 created using posix_fallocate; this bug has been fixed.
171 E2fsck will now correctly mark a sparse journal as invalid and will
172 delete and recreate the journal to address the problem.
174 E2fsck would previously incorrectly ask the user whether she would
175 like to abort the file system check after finding a problem --- and
176 then abort regardless of the user's answer. This is annoying, and
179 E2fsck can now continue even if it fails to recreate the resize
180 inode; previously it would just abort the file system check
183 E2fsck could potentially remove directory entries for inodes found in
184 the unused region of the inode table; this would generally happen on
185 ext4 file systems that do not use journaling. This bug has been fixed
186 by not clearing these directory entries once it has been established
187 that bg_unused_inodes may not be trustworthy; once pass #2 has been
188 completed, e2fsck will restart the file system check from the
189 beginning, and then it will be safe to delete any directory entries
190 pointing to inodes that appear to be deleted. (Addresses Google Bug:
193 E2fsck will not try to set the block group checksums if the user
194 cancels the fsck with a control-C. It's a bad idea to set the
195 checksums if e2fsck hasn't been completed, and it often results an the
196 error message, "Inode bitmap not loaded while setting block group
197 checksum info". (Addresses Launchpad Bug: #582035)
199 The mke2fs program now queries the kernel for the physical as well as
200 the logical sector size, and will not allow a blocksize below the
201 logical, and will strongly encourage a blocksize at least as big as
202 the physical blocksize. This is needed for 4k sector drives that
203 emulate 512 byte sector sizes.
205 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
206 rarely needed, but it is a legal value.
208 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
209 not needed, and offer to clear it; this is a sign of a kernel bug, but
210 more importantly, some released kernels may crash when this situation
211 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
213 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
214 i_size is correct. (Kernels starting with 2.6.34 will set
217 The com_err library will now only output ^M (a CR character) when the
220 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
221 and Vietnamese translations.
223 Fixed various Debian packaging issues --- see debian/changelog for
224 details. (Addresses Debian Bugs: #571247, #563487)
230 The regression test suite now uses its own mke2fs.conf file, so that
231 downstream distributions want change the mke2fs.conf file which is
232 distributed in the RPM or dpkg file, without worrying about screwing
233 up the regression test results.
235 Always build namei.o so that building with configure --disable-debugfs
236 works correctly. Long-term, if we care about reduced e2fsprogs
237 builds, we need a more general solution for deciding what .o files are
238 needed for a particular build. Given that install floppies are going
239 (gone?) the way the dodo bird, we probably don't care, though.
240 (Addresses Sourceforge Bug: #2911433)
242 Add configure options --enable-symlink-build and
243 --enable-symlink-install, which allow e2fsprogs be built using
244 symlinks instad of hard links, and to be installed using symlinks
245 instead of hard links, respectively. It is useful when the file
246 system where the build is taking place, or the file system where
247 e2fsprogs is installed, can't handle hard links for some reason.
248 (Addresses Sourceforge Bug: #1436294)
250 Fixed compile warning in mke2fs.c.
253 E2fsprogs 1.41.11 (March 14, 2010)
254 ==================================
256 E2fsck will no longer give a fatal error and abort if the physical
257 device has been resized beyond 2**32 blocks. (Addresses Launchpad
260 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
261 the allocation status of the block <blk>. (Addresses Debian Bug:
264 E2fsck now prints a much more emphatic and hopefully scary message
265 when a file system is detected as mounted while doing a read/write
266 check of the filesystem. Hopefully this will dissuade users from
267 thinking, "surely that message doesn't apply to *me*" :-(
269 E2fsck -n will now always open the file system read-only. We now
270 disallow certain combination of options which previously were manual
271 exceptions; this is bad because it causes users to think they are
272 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
273 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
275 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
276 it detected a badly aligned partition. Unfortunately, this broke some
277 distribution installation scripts, so it now just prints the warning
278 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
279 Launchpad Bug: #530071)
281 Mke2fs would take a long time to create very large journal files for
282 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
285 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
286 2.6.34 kernels to make e2fsck not complain about blocks deliberately
287 fallocated() beyond an inode's i_size.
289 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
290 e2fsck -fD can corrupt non-indexed directories when are exists one or
291 more file names which alphabetically sort before ".". This can happen
292 with ext2 filesystems or for small directories (take less than a lock)
293 which contain filenames that begin with a space or some other
294 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
301 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
304 The libcom_err function now has support for Heimdal's com_right_r
305 function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
309 E2fsprogs 1.41.10 (February 7, 2010)
310 ====================================
312 Fix resize2fs bug which causes it to access invalid memory.
314 Add libss support for libreadline.so.6.
316 Fix e2fsck's check for extent-mapped directory with an incorrect file
319 Add new e2fsck.conf configuration option, default/broken_system_clock
320 to support systems with broken CMOS hardware clocks. Also, since too
321 many distributions seem to have broken virtualization scripts now,
322 e2fsck will by default accept dates which are off by up to 24 hours by
323 default. (Addresses Debian Bugs: #559776, #557636)
325 Fix a bug where mke2fs may not use the best placement of the inode
326 table when there is only room for a single block group in the last
329 E2fsck is now smarter when it needs to allocate blocks in the course
330 of fixing file system problems. This reduces the number of spurious
331 differences found in pass #5.
333 E2fsck will no longer rehash directories which fit in a single
336 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
337 sparse directories which use extents).
339 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
341 Fix a bug in filefrag where on platforms which can allow file systems
342 with 8k blocks, that it doesn't core dump when it sees a file system
343 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
346 E2fsck will correctly fix directories that are have an inaccurate
347 i_size as well as other problems in a single pass, instead of
348 requiring two e2fsck runs before the file system is fully fixed.
350 Fix e2fsck so it will correctly find and detect duplicate directory
351 entries for non-indexed directories. ( Addresses Sourceforge Bug:
354 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
355 thinly-provisioned storage device. This can be disabled using the -K
358 Enhance libext2fs so it works around bug in Linux version 2.6.19
359 and earlier where the /proc/swaps file was missing the header on
362 Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
363 was missing the header on the first line.
365 Fix some big-endian bugs in e2fsck and libext2fs.
367 Fix resize2fs so it works correctly on file systems with external
368 journals instead of failing early with the error "Illegal inode
371 Fix libss so that it does not seg fault when using a readline library
372 which does not supply a readline_shutdown() function.
374 Updated dumpe2fs's usage message so it correctly gives the right
375 arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
376 (Addresses Launchpad Bug: #448099)
378 Teach libext2fs to ignore the high 32 bits of the i_blocks field
379 when huge_file file system feature is set, but the inode does not
380 have the HUGE_FILE_FL flag set.
382 Fix e2fsck's handling of 64-bit i_blocks fields.
384 E2fsck will now print "Illegal indirect block", "Illegal
385 double-indirect block", etc., instead of "Illegal block #-1" or
386 "Illegal block #-2", etc. This makes it easier for users to
387 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
389 Mke2fs now will obtain get device topology information from blkid and
390 use it to populate the superblock stride and stripe sizes. It will
391 also warn if the block device is misaligned
393 Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
396 Fix the libext2fs library code to round up the bitmap size to a 4-byte
397 boundary, to prevent spurious seg faults caused by the x86
398 architecture. This doesn't affect Linux systems, but was a major
399 problem on a number of *BSD systems. (Addresses Sourceforge Bug:
402 Fix resize2fs's minimum size required for a file system so it doesn't
403 fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
405 Dumpe2fs now prints summary information about the contents of the
408 Avoid printing scary error messages when e2fsck starts running
409 problems on low-memory systems, as it tends to panic and mislead the
410 user. (Addresses Debian Bug: #509529)
412 Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
413 modules files. (Address Red Hat Bug: #518572)
415 Fix tune2fs so it can add a journal when an extent-enabled file system
416 is mounted. (Addresses Launchpad bug: #416648)
418 Update Czech, Indonesian, Polish and Vietnamese translations (from the
419 Translation Project).
421 Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
423 Fixed various Debian packaging issues --- see debian/changelog for
424 details. (Addresses Debian Bugs: #540111)
429 The configure script supports the --with-cc, --with-ccopts, and
430 --with-ldopts options. Instead, the more standard use of CC=,
431 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
432 Also, --with-ld, which never worked, was also removed.
433 (Addresses Sourceforge Bug: #2843248)
435 The in-tree header files are only used if the in-tree uuid or blkid
436 libraries are used. Otherwise, use the system-provided uuid or blkid
437 header files if using the system-provided libraries.
439 Fix some build failures caused by --disable-* configure options.
441 Work around a bug in autoconf 2.64.
444 E2fsprogs 1.41.9 (August 22, 2009)
445 ==================================
447 Fix a bug in e2fsck routines for reallocating an inode table which
448 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
449 filesystem feature with a relatively rare (and specific) filesystem
450 corruption. This fix causes e2fsck to try to find space for a new
451 portion of the inode table in the containing flex_bg, and if that
452 fails, the new portion of the inode table will be allocated in any
453 free space available in the filesystem.
455 Make e2fsck less annoying by only asking for permission to relocate a
456 block group's inode table once, instead of for every overlapping
457 block. Similarly, only ask once to recompute the block group
458 checksums, instead of once for each corrupted block group's checksum.
460 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
461 not present, and it needs to fall back to using the FIBMAP ioctl.
463 Fix filefrag to correctly print the number of extents for zero-length
464 files. (Addresses Debian Bug: #540376)
466 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
467 to more easily debug the FIBMAP code.
469 Fixed filefrag for non-extent based files.
471 Add a new program, e2freefrag, which displays information about the
472 free space fragmentation in an ext2/3/4 filesystem.
474 Fix inode resizing via tune2fs -I so that it works correctly in the
475 face of non-empty bad blocks inodes, and if the filesystem was
476 formatted using the "mke2fs -E stride=N" option for RAID arrays.
478 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
479 and corrupt large directories if the directory needs to shrink by more
480 than one block. (Addresses Debian Bug: #537510)
482 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
483 last mount times are in the future, they are corrected even if
484 buggy_init_scripts is set. This is needed because otherwise resize2fs
485 will refuse to resize the filesystem, even after running "e2fsck -f".
486 (Addresses Launchpad bug: #373409)
488 E2fsck will now print much fuller information when the last mount time
489 or last written time is in the future, since most people can't seem to
490 believe their distribution has buggy init scripts, or they have a
491 failed CMOS/RTS clock battery.
493 Enhance dumpe2fs to dump the extent information via the 'stat'
494 command, and more detailed extent information via the new command
497 Update French, Polish, Czech, and Sweedish translation from the
500 Fixed various Debian packaging issues --- see debian/changelog for
506 Fixed miscellaneous gcc -Wall warnings.
508 Fixed memory leak in error path in ext2fs_block_iterate2()
510 Fixed non-Linux build of the intl directory by adding support for the
513 The bitmap read/write functions now treat uninitialized bitmaps as
514 unallocated; this fixes a number of problems in all e2fsprogs for ext4
515 filesystems when there is a need to allocate new blocks or inodes, and
516 there aren't any free blocks or inodes in the already-used block
519 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
520 get inserted into the extent tree when they are not needed.
523 E2fsprogs 1.41.8 (July 11, 2009)
524 ================================
526 Fix resize2fs's online resizing, fixing a regression which in
527 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
529 Fix potential filesystem corruptions caused by using resize2fs to
530 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
533 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
534 setgid and the currently running program doesn't have write access to
535 the uuidd work directory.
537 Add safety checks (for non-Linux systems) so that uuidd isn't run with
538 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
539 will be careful not to close the file descriptor for its unix domain
540 socket when it detaches itself from the controlling tty. Also add
541 safety checks so that if the unix domain socket between the uuid
542 library and uuidd program is closed for any reason, both the library
543 and the uuidd will return an appropriate error code instead of looping
546 The e2croncheck script, which creates an LVM snapshot and then checks
547 the ext3/4 filesystem via the LVM snapshot, has been added to the
550 Fix filefrag program for files that have more than 144 extents.
552 Update French, Polish, Czech, Indonsian, and Sweedish translation from
553 the Translation Project.
555 Fixed various Debian packaging issues --- see debian/changelog for
556 details. (Addresses Debian Bug #535530)
558 Update/clarify man pages.
563 Fix compilation problem when configured with --disable-uuid.
565 Don't build uuidgen if configured with --disable-uuid.
567 Add the new library function ext2fs_test_inode_bitmap_range(), and
568 optimized ext2fs_test_block_bitmap_range(), which will be needed for
569 future optimizations for e2fsck.
571 Fix makefile dependencies for libcom_err so that the Makefiles work
572 well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
574 Enhance the build system so that the full set of commands executed by
575 the Makefiles are displayed, instead of the Linux kernel summary
576 output, if the build was configured with --enable-verbose-makecmds, or
577 if GNU make is in use and the V variable is non-null, i.e., via "make
581 E2fsprogs 1.41.7 (June 29, 2009)
582 ================================
584 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
585 uninitalized data into the portion of the inode beyond the first 128
586 bytes when operating on inodes mapped via extents; potentially
587 corrupting filesystems.
589 Fix memory leaks in e2fsprogs, including a very large memory leak
590 which can cause e2fsck to run out of memory when checking very large
591 filesystems using extents.
593 The logsave program will now filter out the ^A and ^B characters when
594 writing to the console.
596 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
597 end of the block even if the directory block is corrupted.
599 Fix debugfs from core dumping if the logdump command fails to open the
602 Enhance badblocks to print the currently tested block number when
605 Fix lsattr to exit with a non-zero status when it encounters errors.
606 (Addresses RedHat Bugzilla #489841)
608 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
609 filesystems as the kernel when encoding rec_len >= 64k. For 64k
610 filesystems (currently all that is supported by e2fsprogs, this is
611 only a minor corner case).
613 Resize2fs will now update the journal backup fileds in the sup0erblock
614 if the journal is moved; this avoids an unnecessary full fsck after
615 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)

640 E2fsprogs 1.41.6 (May 30, 2009)
641 ===============================
643 Fix a critical regression in e2fsck introduced version 1.41.5 which
644 can undo updates to the block group descriptors after a journal replay.
646 If e2fsck receives an I/O error while replaying the journal, prompt
647 the user whether they want to ignore the error or not; if e2fsck is
648 run in preen mode, force fsck to abort the preen pass.
650 Fix a bug which would cause e2fsck to core dump if the filesystem
651 contains a corrupt extent header, and the user declines to clear the
652 inode. (Addresses Sourceforge Bug: #2791794)
654 Fix e2fsck to restart only once in the case of multiple block groups
655 which inodes in use that are in the uninitialized part of the block
658 To reduce user confusion, if the /etc/mtab file is missing
659 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
660 new, explicit error code to indicate this case. This will cause
661 e2fsck to give a clearer error message when the user is using buggy
662 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
665 Fix e2fsck so that if the primary group descriptors are corrupted, but
666 the backup superblock is entirely invalid, to go back to using (and
667 fixing) the priary group descriptors instead of completely giving up
668 on the filesystem. (Addresses Debian Bug: #516820)
670 Change e2fsck to not abort a preen pass if an inode is found to have
671 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
672 kernels (post 2.6.29) will ignore this field. So let's fix it
673 automatically during the preen pass instead of forcing the user to fix
674 this up manually. (Addresses Debian Bug: #526524)
676 Add resource tracking for e2fsck passes 1b through 1d.
678 Speed up e2fsck by eliminating unnecessary journal checks if the
679 filesystem is already mounted and doesn't need recovery (since the
680 kernel would have run the journal when the filesystem was mounted.)
681 Also speed up e2fsck by avoiding unnecessary block group descriptor
682 updates in ext2fs_close().
684 Add support to chattr to migrate inodes from using direct/indirect
687 Avoid corrupting the filesystem if there is an attempt to shrink a
688 filesystem using resize2fs smaller than posible by making
689 ext2fs_set_bmap() more careful not to delete the old block until the
690 new block can be inserted. In addition, fix a bug in how the minimum
691 size of the filesystem (plus a safety margin) is calculated, and
692 modify resize2fs to refuse to shrink the filesystem below that minimum
693 size without the force flag.
695 Teach blkid to try to figure out DM device names using take advantage
696 of information in sysfs when running on kernels (2.6.29 and later)
697 which provide this information in /sys/block/dm-<N>/dm/name; this is
698 much faster than scanning for the devncie number in /dev/mapper.
700 Fix blkid to prefer /dev/mapper/<name> device names instad of the
701 private /dev/dm-X names.
703 Add an -a option to debugfs's close_filesys command which writes any
704 changes to the superblock or block group descriptors to all of the
705 backup superblock locations.
707 Add support to the filefrag program to use the FIEMAP ioctl.
709 Update Chinese translation from the Translation Project.
711 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
712 Launchpad Bug: #381854)
714 Fixed various Debian packaging issues --- see debian/changelog for
715 details. (Addresses Debian Bug #506064)
721 Add test code to make sure e2fsck's problem.c doesn't have two problem
722 codes assigned to duplicate values.
724 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
725 (Addresses Sourceforge Bug: #2780205)
727 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
728 function declaration for init_resource_track() and
729 print_resource_track() when RESOURCE_TRACK is not defined.
731 The test code which is used to build the tst_csum progam has been
732 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
733 avoid compile problems caused by not having a prototype for
734 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
736 Update the config.guess and config.sub file to the latest from the
737 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
740 Add a new function, ext2fs_extent_open2(), which behaves like
741 pext2fs_extent_open(), but uses the user-supplied inode structure
742 when opening an extent instead of reading the inode from disk.
745 E2fsprogs 1.41.5 (April 23, 2009)
746 =================================
748 Fix a number of filesystem corruption bugs in resize2fs when growing
749 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
752 Debugfs can now set i_file_acl_high via the set_inodes_field command,
753 and print a 64-bit file acl. This is useful for debugging filesystem
754 corruptions where the high bits of i_file_acl_high are set. E2fsck
755 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
756 since some Linux kernel versions pay attention to this field even when
759 Speed up e2fsck when checking clean filesystems by avoiding
760 unnecessary block reads, and coalescing the block group descriptor
761 blocks so they are read using a single read operation.
763 The libuuid library will now close all file descriptors before running
764 uuidd. This avoids problems when the calling program has open sockets
765 which then never get closed because uuidd is a long-running helper
766 daeomn. (Addresses Launchpad bug: #305057)
768 In order to avoid unnecessary full filesystem checks by e2fsck after
769 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
770 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
772 Mke2fs will avoid trying to create the journal when run in
773 superblock-only mode (mke2fs -S), since the left-over journal in the
774 inode table will cause mke2fs to fail.
776 Fix a bug in libext2fs functions that check to see if a particular
777 device or filesystem image is mounted, which would cause these
778 functions to report that a file identical to the (relative) pathname
779 used by a pseudo-filesystem was mounted when in fact it was not.
781 Update Czech translation from the Translation Project.
783 Add Chinese (simplified) translation from the Translation Project.
785 Fix support for external journals (which was broken in e2fsprogs
788 Fix a regression in debugfs where the "stat" command when no
789 filesystem was open would cause debugfs to crash with a segmentation
792 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
793 used to support filesystems without a journal. Update the blkid
794 library so it understands this.
796 The blkid library will remove an entry from the blkid cache
797 representing the entire disk if partitions are found, since presuambly
798 the device previously had no partition table, but has now transitioned
799 to using a partition table.
801 Add a check to mke2fs and tune2fs that the argument to the -m option
802 (which specifies the reserved ratio) must be greater than zero.
803 (Addresses Debian Bug: #517015)
805 Add support for tracking the number kilobytes written to the
806 filesystem via the superblock field s_kbytes_written. It will be
807 updated by the kernel as well as by e2fsprogs programs which write to
808 the filesystem. This is useful for tracking the wear to filesystems
809 on Solid Sstate Drives.
811 Fix compatibility issue in the libext2fs info file and makeinfo
812 version 4.12. (Addresses Red Hat Bugzilla: #481620)
814 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
816 Fixed various Debian packaging issues --- see debian/changelog for
817 details. (Addresses Debian Bug: #506279)
822 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
825 Fix various gcc compilation warnings and other programming cleanups.
826 (Addresses Red Hat Bugzilla: #486997)
828 Add support for building the blkid command statically.
830 Add support for disabling the built-in blkid library in favor of a
831 system-installed blkid implementation via the configure option
835 E2fsprogs 1.41.4 (January 27, 2009)
836 ===================================
838 Fixed a bug which could sometimes cause blkid to return an exit value
839 of zero for a non-existent device (Addresses Debian Bug: #502541)
841 Blkid will now recognize ext3 filesystems that have the test_fs flag
842 set as ext3 filesystems.
844 The blkid library will now recognize btrfs filesystems and swap
845 devices currently used by user-level software suspend.
847 Tune2fs now updates the block group checksums when changing the UUID
848 to avoid causing e2fsck to complain vociferously at the next reboot.
850 Tune2fs's inode size resizing algorithms have been fixed so it is not
851 vastly inefficient for moderate-to-large filesystems, due to some
852 O(n**2) and O(n*m) algorithms that didn't scale well at all.
854 Fix tune2fs's inode resizing algorithm so it will not corrupt
855 filesystems laid out for RAID filesystems; in addition, tune2fs will
856 refuse to change the inode size for filesystems that have the flex_bg
857 feature enabled. (This is a limitation in the current implementation
860 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
861 filesystems with 32-bit block numbers, when the headers for 64-bit
862 block numbers was added. This regression has been fixed.
864 Debugfs's ncheck command has been fixed to avoid printing garbage
865 characters at the end of file names.
867 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
868 when shrinking filesystems with uninit_bg feature would not be moved.
869 In addition, blocks and inode table blocks were not being correctly
870 freed when shrinking filesystems with the flex_bg feable, which caused
871 resize2fs -M to fail. Finally, when blocks are moved, make sure the
872 uninitialized flag in extents is preserved.
874 Fix bug which caused dumpe2fs to abort with an error if run on a
875 filesystem that contained an external journal.
877 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
878 for this in argv[0] to provide better legacy support for these
879 distributions. This is a practice that should NOT be continued,
882 Mke2fs now has a new option -U, which allows the user to specify the
883 UUID that should be used for the new filesystem.
885 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
886 minus one block. This allows users who have read that ext3 supports
887 up to 16TB filesystems and who create a 16TB LVM to not get confused,
888 since the true limit is really 16TB minus one block.
890 E2fsck will no longer abort an fsck run if block group has an errant
893 E2fsck now distinguishes between fragmented directories and fragmented
894 files in verbose mode statistics and in the fragcheck report.
896 Fix a bug in e2fsck which casued it double count non-contiguous
899 E2fsck will leave some slack space when repacking directories to allow
900 room for a few directory entries to be added without causing leaf
901 nodes to be split right away.
903 Fix a bug which caused e2fsck to crash when it comes across a
904 corrupted interior node in an extent tree with the error message:
905 "Error1: Corrupt extent header on inode XXXXXX"
907 E2fsck problem descriptions involving the journal are no longer
908 referred to as "ext3" problems, since ext4 filesystems also have
911 Fix a long-standing bug in e2fsck which would cause it to crash when
912 replying journals for filesystems with block sizes greater than 8k.
914 Update Catalan translation from the Translation Project.
916 Fixed various Debian packaging issues --- see debian/changelog for
917 details. (Addresses Debian Bugs: #503057, #502323, #511207)
922 Fix build of e2fsck.profiled, and add support for building profiled
923 binaries in the misc directory if configured with --enable-profile.
925 The ext2fs_open() function now performs more sanity checks on the
926 superblock to avoid potential divide by zero errors by other parts of
929 The ext2fs_read_inode_full() function now has a safety check to avoid
930 a segmentation fault on corrupted filesystems.
932 The ext2fs_new_inode() function now has a sanity check so that if the
933 s_first_inode field in the superblock is insane, it will return
934 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
936 To avoid segmentation faults, ext2fs_block_alloc_stats() and
937 ext2fs_inode_alloc_stats() now validates the passed inode or block
938 number to avoid overrunning an array boundary.
940 Various signed/unsigned errors for variables containing block numbers
943 Accomodations for gcc's stupidity in not realizing that constant
944 strings that do not contain a '%' character are safe to use in format
945 strings have been made so that distributions that want to compile
946 e2fsprogs with -Werror=format-security have an easier time doing so.
948 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
950 Added the utility make-sparse.c to the contrib directory.
952 The ext2fs_block_iterate2() function now reflects errors from
953 ext2fs_extent_set_bmap() to the caller, if the callback tries to
954 change a block on an extent-based file, and ext2fs_extent_set_bmap()
955 fails for some reason (for example, there isn't enough disk space to
956 split a node and expand the extent tree.
958 The ext2fs_block_iterate2() function will preserve the uninit flag in
959 extents when the callback function modifies a block in an extent-based
962 E2fsck will now flag filesystems that have an insane s_first_ino field
963 in their superblock, and attempt to use a backup superblock to repair
967 E2fsprogs 1.41.3 (October 12, 2008)
968 ===================================
970 E2fsck has been fixed so it prints the correct inode number for
971 uinit_bg related problems.
973 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
974 is available on linux. This can be disabled via a configuration
975 option in /etc/e2fsck.conf.
977 Fix a file descriptor leak in libblkid when checking to see if an ext4
978 or ext4dev module exists.
980 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
981 while trying to close a filesystem can lead to infinite loops.
982 (Addresses Red Hat Bugzilla #465679)
984 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
985 will cause resize2fs to drop into an infinite loop. (Addresses Red
986 Hat Bugzilla: #465984)
988 Add a check in the Unix I/O functions in libext2fs so that when a
989 device is opened read/write, return an error if the device is
990 read-only using the BLKROGET ioctl.
992 Fix debugfs's ncheck command so that it prints all of the names of
993 hardlinks in the same directory.
995 Fix a bug in libblkid so it correctly detects whether the ext4 and
996 ext4dev filesystems are available, so that the ext4dev->ext4
997 fallback code works correctly.
1002 Fix a parallel build problem by making sure util/subst is built before
1003 trying to build the lib/et directory. (Addresses Sourceforge Bug:
1006 Updated "make depend" information for crc16.o
1009 E2fsprogs 1.41.2 (October 2, 2008)
1010 ==================================
1012 Fix e2fsck's automatic blocksize detection. This fixes a regression
1013 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1014 specifies a block number using the -b option if the blocksize option
1015 isn't also specified using -B. Unfortunately, users very commonly
1016 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1017 superblock; in fack e2fsck will often suggest this kind of command
1020 Enhance the debugfs's "ncheck" command so it will print all of the
1021 pathnames for the specified inodes. (Previously, in some cases ncheck
1022 might not print a pathname for an inode at all if some of the other
1023 inodes had multiple hard links.)
1025 Enhance debugfs's "hash" command so the hash seed can be specified via
1026 a command-line option. In addition, allow the hash algorithm to be
1027 specified by name instead of just by number.
1029 Fix e2fsck so that we don't accidentally print the translation file's
1030 header when asking the user a custom question so there is no prompt
1031 defined for a particular problem record. For example, the question
1032 "Run journal anyway" will get the PO header tacked on because e2fsck
1033 erroneously passed the null string to _(). (Addresses Launchpad Bug:
1036 Enhance badblocks so that it can test a normal file which is greater

1061 Fixed various Debian packaging issues --- see debian/changelog for
1062 details. (Addresses Debian Bug: #497619)
1067 Fix a potential file descriptor leack in libcom_err by setting the
1068 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
1071 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
1072 has been carrying a patch for a long time to prevent a largely
1073 theoretical race condition if a multi-threaded application adds and
1074 removes error tables in multiple threads. Unfortunately SuSE's
1075 approach breaks compatibility by forcing applications to link and
1076 compile with the -pthread option; using pthread mutexes has
1077 historically been problematic. We fix this by using sem_post/sem_init

1081 Sourceforge Bug: #2087502)
1083 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
1084 libraries when using ELF shared libraries.

1087 have the e2fsprogs shared libraries already installed. (Addresses
1088 Sourceforge Bug: #2088537)
1090 Fix the pkg-config files so they work correctly when linking with
1091 static libraries and fix the include directory so programs don't have

1093 instead. (Addresses Sourceforge Bug: #2089537)
1095 Make sure ext2fs_swab64() is compiled for all platforms, and not just
1096 for x86. (Addresses Debian Bug: #497515)
1098 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1099 non-x86 platforms. (They had been removed for x86 earlier.)
1101 Fix diet libc compilation support, which had bitrotted due to lack of
1102 TLC. Fixing this improves general portability.

1114 E2fsprogs 1.41.1 (September 1, 2008)
1115 ====================================
1117 Many people are forgetting to update their mke2fs.conf file, and this
1118 causes ext3, ext4, and ext4dev filesystems won't get created with the
1119 proper features enabled. We address this in two ways. First, mke2fs
1120 will issue a warning if there is not definition for an ext3, ext4, or
1121 ext4dev filesystem and the user is trying to create such a filesystem
1122 type. Secondly, when installing from a source build, "make install"
1123 will provide basic configuration file handling for /etc/mke2fs.conf.
1124 If it exists, and does not mention ext4dev, it will be moved aside to
1125 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1126 be installed. If the existing /etc/mke2fs.conf file does mention
1127 ext4dev, then "make install" will install official mke2fs.conf file as
1128 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1129 they should look to see if any changes need to be merged.
1131 The mke2fs program will now create the journal in the middle of the
1132 filesystem, since this minimizes seek times on average for fsync-heavy
1133 workloads. In addition, mke2fs will now create journals using extents
1134 for filesystems that support them. This results in a more efficient
1135 encoding for the journal since it eliminates the need for using
1138 The mke2fs program will avoid allocating an extra block to the
1139 journal. (Addresses Sourceforge Bug: #1483791)
1141 Mke2fs will correctly enforce the prohibition against features
1142 (specifically read-only features) in revision 0 filesystems. (Thanks
1143 to Benno Schulenberg for noticing this problem.)
1145 Mke2fs previously would occasionaly create some slightly non-optimally
1146 placed inode tables; this bug has been fixed.
1148 The mke2fs and tune2fs programs now print the correct usage message
1149 describing the maximum journal size. (Addresses Debian Bug: #491620)
1151 Add support for setting the default hash algorithm used in b-tree
1152 directories in tune2fs (from a command-line option) or mke2fs (via
1153 mke2fs.conf). In addition, change the default hash algorithm to
1154 half_md4, since it is faster and better.
1156 The blkid library will now recognize MacOS hfsx filesystems, and
1157 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1158 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1160 The blkid library has improved detection of JFS and HPFS filesystems.
1161 (Addresses Launchpad Bug: #255255)
1163 The blkid library is now much more efficiently handling devicemapper
1164 devices, mainly by no longer using the devicemapper library. This can
1165 speed up access for systems with a large number of device mapper
1168 Blkid had a number of cache validation bugs in libblkid that have been
1169 fixed. (Addresses Debian Bug: #493216)
1171 Resize2fs will now properly close out the "updating inode references"
1172 progress bar so there is a newline printed before printing the final
1173 "resize is successful" message.
1175 Resize2fs will now correctly handle filesystems with extents and/o
1176 uninitialized block groups correctly when file/directory blocks need
1177 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1178 is not present). To support this, the ext2fs library now supports
1179 initializing inode and block bitmaps that are not yet initialized when
1180 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1181 addition, e2fs_block_iterate2() can now support changing the location
1182 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1183 been optimized to avoid creating unnecessary new extents when updating
1184 the location of blocks in the extent tree. This will also help out
1185 e2fsck's recovery of obscurely corrupted filesystems with extents,
1186 when blocks are claimed by multiple inodes.
1188 Add support for on-line resizing ext4 filesystem with the flex_bg
1189 filesystem feature. The method for doing so is not optimal, but to do
1190 a better job will require kernel support.
1192 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1193 debugfs programs to not be able to read e2image files; the signed
1194 vs. unsigned bug in the code which read bitmaps from the e2image has
1195 been fixed. (Addresses Debian Bug: #495830)
1197 Resize2fs is now correctly managing the directory in-use counts when
1198 shrinking filesystems and directory inodes needed to be moved from one
1199 block group to another. This bug has been around since e2fsprogs
1200 1.26, and is largely harmless, but does cause a filesystem corruption
1201 which will be flagged by e2fsck after the filesystem has been shrunk.
1203 E2fsck will no longer issue spurious complaints about the inode size
1204 caused by very large extent-based files, and by blocks reallocated
1205 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1206 Kernel Bugzilla: #11341)
1208 Mke2fs will now set the creation timestamp on the lost+found directory
1209 and the root directory. (More generally, all new inodes created using
1210 the ext2fs library will correctly set the creation timestamp.)
1212 E2fsck now correctly calculates ind/dind/tind statistics in the
1213 presence of extent-based files. In addition, "e2fsck -v" will report
1214 statistics of the depth of extent trees in the filesystem. E2fsck can
1215 also give an inode fragmentation report using "e2fsck -E fragcheck"
1216 which can be useful when debugging the kernel block allocation
1219 Fix support for empty directory blocks in ext4 filesystems with 64k
1220 blocksize filesystems.
1222 E2fsck will now print the depth of corrupt htree directories.
1224 Debugfs's htree command now correctly understands extent-based
1225 directories. It will also print out the minor hash as well as the
1228 Debugfs has a new command which will print the supported features of
1229 e2fsprogs, to enable scripts to know whether the installed version of
1230 e2fsprogs can support a specific feature.
1232 Debugfs will now write files using extents for filesystems that
1235 The error message printed by "tune2fs -I" if the inode size was too
1236 small was rather confusing, so it has been improved. Also, we won't
1237 try to create an undo log until we know that command-line-specified
1238 parameters such as "tune2fs -I <inode size>" are valid.
1240 Given some filesystems found "in the wild" that had non-zero block
1241 group checksums even though the uninit_bg/gdt_sum feature was not
1242 enabled, e2fsck would issue spurious error messages. Teach
1243 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1244 entirely if the feature flag is not set. (Addresses Debian Bug:
1247 The blkid program will now print out a user-friendly listing of all of
1248 the block devices in the system and what they contain when given the
1249 -L option. (Addresses Debian Bug: #490527)
1251 The filefrag program now has a more accurate calculation for the
1252 number of ideal extents. (Addresses Debian Bug: #458306)
1254 The test I/O manager is now enabled by default, but its overhead is
1255 only incurred when it would be enabled via the TEST_IO_FLAGS or
1256 TEST_IO_BLOCK environment variables.
1258 Typographical errors in various program strings and usage messages
1259 have been fixed; most of these were pointed out by the e2fsprogs
1260 message catalog translators. (Thanks, translators!)
1262 Update and clarified various man pages, as well as some typographical
1263 errors in the libext2fs texinfo file.

1285 Sourceforge Bug: #2019287)
1287 The ext2fs_extent_set_bmap() had some bugs when setting the first
1288 block in a file, or when replacing a single block extent. Those cases
1289 fortunately were came up relatively rarely when e2fsck was checking
1290 files, but caused some problems when resize2fs was shrinking

1301 Ext2ed was failing to build because masix support had been removed in
1302 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
1304 The configure script now respects the LDFLAGS environment variable if
1305 it is set when configure is called. (Addresses Sourceforge Feature
1308 Libuuid is now more portable to the Windows platform. (Addresses
1309 Sourceforge Feature Request: #1937287)
1311 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1312 bare echo commands so that configure flags such as --quiet work
1313 correctly. (Addresses Sourceforge Patches: #2058794)

1327 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1328 top-level Makefile. That automatic rule is used to better support
1329 SCCS, but it caused problems for a particular niche distribution which
1330 likes to use configure.sh files to store the configure options used to
1331 build a package. Unfortuntaely GNU make will use the configure.sh to
1332 replace the configure script, resulting in a self-inflicted fork bomb
1333 leading to an out-of-memory crash.
1335 To support old GNU C compilers don't use C99/C++ comments, but only
1336 K&R style comments, and don't try to use __builtin_expect if __GNUC__
1337 is less than 3. (__builtin_expect is only supported for gcc versions
1338 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1339 this is an optimization, we only try to use __builtin_expect for gcc 3
1342 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
1343 __LITTLE_ENDIAN, which are only defined by glibc's header files and
1344 hence isn't portable.
1346 For the convenience for some distributions that need a static tune2fs,
1347 the Makefile for misc/ now has a tune2fs.static target.
1349 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1350 for extent-based files
1352 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1355 All source files no longer have any trailing white space.
1357 The io_channel_read_blk64() and io_channel_write_blk64() functions are
1358 now functions instead of C preprocessor macros to provide better
1359 forward compatibility.

1368 E2fsprogs is now more portable to Solaris.
1369 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
1371 * Scripts do not assume that /bin/true is always in /bin
1372 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
1373 * Flush stdio handles before calling setbuf(), since Solaris will
1374 discard any pending output to the stream.
1375 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
1376 picky about which C compiler can beused for SUSv3 conformance.
1377 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
1378 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
1379 Since we need some SUSv3 functions, consistently use SUSv3 so
1380 that e2fsprogs will build on Solaris using c99.
1381 * Solaris C99 does not support varargs C preprocessor macros
1382 * Solaris header files pollute the C namespace if in/netinet.h
1383 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
1385 * Solaris ships with a pathetically ancient shell in /bin/sh so we
1386 avoid the use of various more avanced shell constructs such as $().
1388 The "make rpm" command will now take some extra configure optiosn from
1389 the build environment without needing to patch the source tree.
1391 The ext2fs_add_dir_block() function will now grow the dblist more
1392 aggressively as an optimization to avoid copying the array too often.
1394 The e2fsck_write_bitmaps() will write the block and inode bitmaps
1395 together instead of in two passes.
1398 E2fsprogs 1.41 (July 10, 2008)
1399 ==============================
1401 Add support for ext4 filesystem features, in particular extents,
1402 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
1403 support for checking journal checksums. Debugfs will print new
1404 superblock and inode fields that were defined for ext4. For example,
1405 the nanosecond and i_version fields of an inode, and the
1406 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1407 Note: Resize2fs doesn't currently support the combination of flex_bg
1408 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
1410 Tune2fs can support migrating a filesystem from using 128 byte inodes
1411 to 256 byte inodes, so it can take advantage of the full features of
1414 Add support for "undo" support. E2fsck and mke2fs can optionally
1415 record an undo log which can replayed by the program e2undo.
1417 E2fsck could damage a filesystem by trying to relocate inode tables
1418 due to corrupted block group descriptors, where the attempted inode
1419 table relocation would do far more harm than good. E2fsck has been
1420 fixed to detect this these sorts of corrupted block group descriptors
1421 much earlier in e2fsck processing, so it can try to use the backup
1422 superblock and block group descriptors first. This should be a much
1423 better strategy for recovering these types of corrupted filesystems.
1424 (Addresses Sourceforge Bug: #1840291)
1426 E2fsck will display a more understandable message when the last check
1427 field in the superblock is in the future. (Addresses Debian Bug:
1430 E2fsck now performs more extensive and careful checks of extended
1431 attributes stored in the inode.
1433 Enhance mke2fs to print a more explanatory error message when
1434 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
1437 Fix mke2fs to use a default block size of 4k when formatting an
1438 external journal device. This is done by using a fixed filesystem
1439 type list that consists only of the single filesystem type "journal"
1440 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
1441 Debian Bug: #488663)
1443 Speed up how mke2fs writes the journal data blocks by writing the disk
1444 blocks in larger chunks.
1446 Fix blkid handling of stale devices. Fix a bug which could cause a
1447 core dump while garbage collecting the blkid cache, and assure that
1448 blkid_find_dev_with_tag() never returns a non-existent device. Also,
1449 if a filesystem is found at a new /dev location, eliminate any
1450 duplicate stale entries which can not be verified.
1451 (Addresses Debian Bugs: #487758, #487783)
1453 Add more paranoid checks for LVM volumes and swap partitions in
1454 blkid's probe function, to reduce the chances of false positives.
1456 The mke2fs program now has a much more sophisticated system for
1457 controlling configuration parameters of a newly created filesystem
1458 based on a split filesystem and usage type system. The -t option to
1459 mke2fs was a deprecated alias to -c; it now specifies a filesystem
1460 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1461 separated usage list. The filesystem type information and type
1462 information is used to extract configuration parameters from the
1463 /etc/mke2fs.conf file.
1465 The mke2fs program will no longer complain and request the -f option
1466 when the user tries to create a filesystem with greater than 2**31
1469 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1470 adjust the mke2fs.conf file so filesystems for the Hurd are created
1471 with a blocksize of 4096 and inode size of 128, which is all it knows
1472 how to handle. (Addresses Debian Bug: #471977)
1474 Mke2fs will always make sure that lost+found always has at least 2
1475 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1477 Resize2fs will now print the minimum needed filesystem size if given
1478 the -P option, and will resize the filesystem to the smallest possible
1479 size if given the -M option.
1481 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1482 blocks are consumed during an off-line resize.
1484 The "ls" command in debugfs now supports the -p option, which causes
1485 it to quote the filenames so that spaces or tabs in directory entries
1486 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
1487 Sourceforge Feature Request: #1201667)
1489 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1492 The chattr program will return a non-zero exit code in case of
1493 failures, and error messages can be suppressed with the -f option.
1494 (Addresses Red Hat Bugzilla: #180596)
1496 Fix a bug in badblocks which caused it to overrun an array and likely
1497 crash if more than 8 test patterns are specified using the -t option.
1498 (Addresses Debian Bug: #487298)
1500 Add support to badblocks to limit how quickly it reads from the disk
1501 drive (so it can be used for background scrubbing), and so it will
1502 abort after finding a given number of errors.
1504 Remove support for the legacy big-endian filesystem format which only
1505 existed on extremely long-dead PowerPC kernels almost a decade ago.
1507 Remove MASIX support from e2fsprogs.
1509 Add I/O statistics reporting to e2fsck.

1538 Avoid using predictable filenames in /tmp in blkid's regression test
1539 suite. Also remove bashism's in the regression test script.
1541 If the configure script is given --with-diet-libc, don't use thread
1542 local storage, since diet libc doesn't support TLS. (Addresses
1543 Sourceforge Bug: #2000654)
1545 Fix the blkid regression test suite to tolerate older versions of
1546 mkswap that don't support the -U option.
1548 A few library routines have been converted to support 64-bit block
1549 numbers; in particular, the I/O manager functions, the test_io,
1550 inode_io, and unix_io managers have all be converted to support 64-bit
1553 Debugfs can now be extended for use by test programs. See
1554 lib/ext2fs/extents.c for an example for how it can be used. The test
1555 program links against the debugfs object files, and provides
1556 additional commands by defining an auxiliary libss command table.
1558 The lazy_bg filesystem feature, which was only used by developer's
1559 testing, has been removed since it has been largely supplanted by
1560 uninit_bg. This also simplifies the code.
1563 E2fsprogs 1.40.11 (June 17, 2008)
1564 =================================
1566 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
1567 percentage of reserved blocks. (Addresses Debian Bug: #452639)

1587 Fix ext2fs_swap{16,32,64} functions so they can be used by external
1588 applications on big-endian machines. (Addresses Debian Bug: #484879)
1591 E2fsprogs 1.40.10 (May 21, 2008)
1592 ================================
1594 When deciding whether or not to revalidate a blkid cache entry, if the
1595 device's mtime is newer than the last time the cached entry was
1596 validated, force a revalidation.
1598 Fix a potential data corruption bug in e2fsck in the journal replay.
1599 The chances of this is happening is extremely remote, especially the
1600 default data=ordered or data=writeback modes. However, if a block
1601 which has been journalled starts with the first four bytes 0xc03b3998,
1602 when e2fsck replays the journal, those four bytes will be replaced
1603 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1604 metadata to begin with those fatal 4 byte sequence, and unless
1605 data=ordered mode is in use, data blocks are never journaled.
1607 Updated German, Dutch, Sweedish, and Vietnamese translations.
1612 Fixed various Debian packaging issues --- see debian/changelog for
1615 Remove default sizes of types when cross compiling, since autoconf
1616 2.50 can figure this out automatically now.
1619 E2fsprogs 1.40.9 (April 27, 2008)
1620 =================================
1622 SuSE's security team audited uuidd and came up with a few minor
1623 issues. None of them are serious given that uuidd runs setuid as a
1624 unprivileged user which has no special access other than libuuid
1625 directory, but it's good to get them fixed.
1627 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1628 work correctly with in-inode extended attributes.

1689 E2fsprogs 1.40.8 (March 13, 2008)
1690 =================================
1692 Fixed e2image -I so it works on image files which are larger than 2GB.
1694 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1695 the size is larger than the number of blocks found in the inode, don't
1696 try to allocate extra empty blocks at the end of the directory to make
1697 up the difference; there's no point to doing that. In addition, if
1698 the size is not a multiple of a blocksize, always fix it.
1700 E2fsck handled a pass 2 "should never happen error" by not giving
1701 enough information and then core dumping. Unfortunately, it was all
1702 too easy to trigger the "should never happen" situation if a
1703 directory's inode size was not correct. This has been fixed, but
1704 e2fsck has also been taught how to handle this situation more
1705 gracefully, by simply removing the inode hash tree information, so
1706 that it can be rebuilt again after e2fsck's pass 3. (Addresses
1707 Launchpad Bug: #129395)
1709 Resize2fs had a bug resizing large inodes with extended attributes
1710 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1711 completely on big-endian systems such as PowerPC. The bug should be
1712 completely fixed now. Yay for regression test suites. (Addresses Red
1713 Hat Bugzilla: #434893)

1729 Add new functions, ext2fs_dblist_get_last() and
1730 ext2fs_dblist_drop_last(), which allows the caller to examine the last
1731 directory block entry added to the list, and to drop if it necessary.
1733 Fixed a portability problem in libblkid with DJGPP.
1735 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
1736 to Philipp Thomas for pointing this out.

1739 fail with an error code.
1742 E2fsprogs 1.40.7 (February 28, 2008)
1743 ====================================
1745 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1746 depreciate the -s option, since it can result in filesystems which
1747 e2fsck can't fix easily. There are very good reasons for wanting to
1748 disable sparse_super; users who wants to turn off sparse_super can use
1749 debugfs. (Addresses Sourceforge Bug: #1840286)
1751 Add missing options to mke2fs's usage message. (Addresses Sourceforge
1754 Fix bug in resize2fs when large (greater than 128 byte) inodes are
1755 moved when a filesystem is shrunk; it was only moving the first 128
1756 bytes, so extended attributes were not getting moved. (Addresses Red
1757 Hat Bugzilla: #434893)

1777 Change e2fsck to no longer clear the LARGE_FILES feature flag
1778 automatically, when there are no more > 2GB files in the filesystem.
1779 It's been almost a decade since there have been kernels that don't
1780 support this flag, and e2fsck clears it quietly without telling the
1781 user why the filesystem has been changed.
1783 Fix bug which could cause libblkid to seg fault if a device mapper
1784 volume disappears while it is being probed. (Addresses RedHat
1787 Inhance e2fsck's reporting of unsupported filesystem feature flags.

1790 Fix option syntax in dumpe2fs for explicit superblock and blocksize
1791 parameters. What was currently documented in the man page has been
1792 broken for some time, due to getopt() implementation changes. The
1793 option sytax has been changed to one which is can be more portable
1794 supported and which is consistent with the format for extended options
1795 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
1797 Add support to tune2fs to clear the resize_inode feature. This
1798 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)

1832 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
1833 partially filled-in filesystem object on an error, so that e2fsck can
1834 print more intelligent error messages.
1836 Add a new function e2p_edit_feature2() which allows the caller to
1837 specify which feature flags are OK to set or clear, and which returns

1902 ===================================
1904 Fix a potential overflow big in e2image if the device name is too
1907 Mke2fs will now create new filesystems with 256 byte inodes and the
1908 ext_attr feature flag by default. This allows for much better future
1909 compatibity with ext4 and speeds up extended attributes even on ext3
1912 Teach e2fsck to ignore certain "safe" filesystem features which are
1913 set automatically by the kernel. Having the kernel set features
1914 automagically behind the user's back is a bad idea, and we should try
1915 to break the kernel of this habit, especially for the newer ext4
1916 feature flags. But for now, we will try to avoid needless full checks
1917 which can annoy users who are doing fresh installs.
1919 Add support in tune2fs and mke2fs for making a filesystem as being "ok
1920 to be used with test kernel code". This will be needed for using test
1921 filesystems with the latest ext4 kernel code.
1923 Change e2fsck -fD so that it sorts non-htree directories by inode
1924 numbers instead of by name, since that optimizes performances much
1925 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
1927 If e2image fills the disk, fix it so it exits right away instead of
1928 spewing large numbers of error messages.
1929 (Addresses-Sourceforge-Feature-Request: #606508)
1931 If ftruncate64() is not available for resize2fs, let it use ftrucate()
1932 instead, but have it check to see if the size would get truncated, and
1933 skip calling ftruncate in that case.
1935 Add support for detecting HFS+ filesystems in the blkid library.
1937 Add supprt in the blkid library for ext4/ext4dev filesystems.

1952 Allow the debugfs 'undel' command to undelete an inode without linking

1993 Improve time-based UUID generation. A new daemon uuidd, is started
1994 automatically by libuuid if necessary. This daemon is setuid to allow
1995 updates to /var/lib/libuuid, so the clock sequence number can be

2045 E2fsprogs 1.40.3 (December 5, 2007)
2046 ===================================
2048 Fix a potential security vulnerability where an untrusted filesystem
2049 can be corrupted in such a way that a program using libext2fs will
2050 allocate a buffer which is far too small. This can lead to either a
2051 crash or potentially a heap-based buffer overflow crash. No known
2052 exploits exist, but main concern is where an untrusted user who
2053 possesses privileged access in a guest Xen environment could corrupt a
2054 filesystem which is then accessed by the pygrub program, running as
2055 root in the dom0 host environment, thus allowing the untrusted user to
2056 gain privileged access in the host OS. Thanks to the McAfee AVERT
2057 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2059 Fix hueristics in blkid which could cause a disk without partitions to
2060 be incorrectly skipped when a loopback device is present. (Addresses
2061 Red Hat Bugzilla #400321.)
2063 Fix e2image so that in raw mode it does not create an image file which
2064 is one byte too large.
2066 Change mke2fs's usage message so it recommends the preferred -E option
2067 instead of the deprecated -R option.
2069 Enhance the blkid library so it will recognize squashfs filesystems.
2070 (Addresses Red Hat Bugzilla #305151.)
2072 Enhance e2fsck so it will force the backup superblocks to be backed up
2073 if the filesystem is consistent and key constants have been changed
2074 (i.e., by an on-line resize) or by e2fsck in the course of its
2077 Enhance blkid's detection of FAT filesystems; so that USB disks with
2078 only a single bootable partition will not get missed.
2080 E2fsck will no longer mark a filesystem as invalid if it has time
2081 errors (i.e., if superblock mount time or last write time is in the
2082 future) and the user refuses to fix the problem.
2084 The Ubuntu init scripts don't properly set the system time correctly
2085 from hardware clock if the hardware clock is configured to tick local
2086 time instead of GMT time. Work around this as best as we can by
2087 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2088 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2091 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2092 Hat Bugzilla #151533.)
2094 Fix e2fsck so that if the superblock is corrupt, but still looks
2095 vaguely like an ext2/3/4 superblock, that it automatically tries to
2096 fall back to the backup superblock, instead of failing with a hard
2099 Make the e2fsprogs program more robust so that they will not crash
2100 when opening a corrupt filesystem where s_inode_size is zero.
2102 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2103 arguments are detected as such and the parse error is reported to the
2104 user. (Addresses Debian Bug #435381.)
2106 Change e2fsck so it will not complain if a file has blocks reallocated
2107 up to the next multiple of a system's page size.
2109 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2110 about (valid) filesystems where the inode table extends to the last
2111 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2113 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2114 allocating inode tables for some relatively rare odd disk sizes.
2115 (Addresses Red Hat Bugzilla #241767.)
2117 Add Catalan translation and update Dutch and Swedish translations
2118 from the Translation Project.
2120 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2121 still had an issue when trying to figure out whether we need to
2122 byte-swap fast symlinks that contained extended attributes.
2124 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2125 (Addresses SourceForge Bug #1821333.)
2131 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
2133 Add "make check" to the RPM spec file
2135 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2136 works correctly when the prefix is not the root directory.
2138 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2139 clena up after themselves by deleting the test.img temporary file
2140 after completing the test.
2142 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2143 first directory entry in a directory block and the last directory
2144 entry in the previous directory block is not in use. Fortunately
2145 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2146 places where it is extremely unlikely to run into this corner case.
2148 Fix missing dependency which would cuase parallel builds to fail.
2149 (Addresses Sourceforge Bug #1842331.)
2151 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2152 calling open(O_CREATE) with a missing mode parameter.
2154 Fix the test_ss.c in lib/ss so it can be used as an example
2155 application program for the library as well as a regression test
2158 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2159 are properly passed back up through the call stack.
2161 E2fsprogs 1.40.2 (July 12, 2007)
2162 ================================
2164 A recent change to e2fsck_add_dir_info() to use tdb files to check
2165 filesystems with a very large number of filesystems had a typo which
2166 caused us to resize the wrong data structure. This would cause a
2167 array overrun leading to malloc pointer corruptions and segfaults.
2168 Since we normally can very accurately predict how big the the dirinfo
2169 array needs to be, this bug only got triggered on very badly corrupted
2172 Fix a bug in e2fsck which caused it to incorrectly salvange
2173 directories when the last entry's rec_len is bogusly too big. This
2174 resulted in a nonsense filesystem corruption to be reported, and
2175 required a second run of e2fsck to fully fix up the directory.
2177 Update tune2fs man page to include more discussion of reserved blocks
2178 (Addresses Launchpad bug #47817)
2180 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2184 E2fsprogs 1.40.1 (July 7, 2007)
2185 ===============================
2187 Fix bug which could cause libblkid to loop forever. When revalidating
2188 a partition where there is obsolete information in /etc/blkid.tab, we
2189 end up freeing a the type tag without clearing dev->bid_type, causing
2190 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2192 The Turkish translation has a bug in it where it has the translation
2193 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2194 @E, recursively, forever, until the stack fills up and e2fsck core
2195 dumps. We fix this by making e2fsck stop @-expansions after a
2196 recursive depth of 10, which is far more than we need.
2197 (Addresses Sourceforge Bug: #1646081)
2199 Compile the default mke2fs.conf into mke2fs program. People are
2200 getting surprised by mke2fs creating filesystems with different
2201 defaults than earlier versions of mke2fs if mke2fs.conf is not
2202 present. So we now create a built in version of mke2fs.conf file
2203 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2204 (Addresses SourceforgeBug: #1745818)
2206 Improve the config/parse_types.sh helper script. Fix a potential
2207 security problem if e2fsprogs is built as root (as Gentoo does!). In
2208 addition fix the script and how it is called from the configure script
2209 so that it does the right thing when cross-compiling. (Fixes Gentoo
2212 Update Vietnamese, French, and Dutch PO files from the Translation
2213 Project. Also created a new e2fsprogs.pot file for translator.
2215 Fix bogus strip permission errors when building under Debian. When
2216 building the e2fsprogs dpkg's, the dh_strip command emits a large
2217 number of error messages caused by the permissions not being right.
2218 So run dh_fixperms before running dh_strip.
2223 Add new function: profile_set_default(). This function sets the value
2224 of the pseudo file "<default>". If the file "<default>" had
2225 previously been passed to profile_init(), then def_string parameter
2226 will be parsed and used as the profile information for the "<default>"
2229 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2230 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2231 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2233 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2234 priority" environment variable that overrides all others, where as
2235 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2236 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2237 the all the rest are set. This will assure that the locale when
2238 running the test suites is the "C" locale. (Obviates Gentoo patch:

2243 ==============================
2245 Fix divide by zero error in blkid's NTFS probing logic.
2247 Add new blkid -g option which causes the blkid cache to be garbage
2250 Fix a bug in libblkid which could cause the internal field bid_type to
2251 become corrupted. Fortunately bid_type isn't used much, and bid_label
2252 and bid_uuid is only used by debugging code, so the impact of this bug
2255 Mke2fs will now store the RAID stride value when a filesystem is
2256 created with a requested RAID stride, and then use it automatically in
2259 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2260 isn't too big. In some cases Lustre users have tried specifying an
2261 inode size of 4096 bytes, while keeping an inode ratio of one inode
2264 Improve sanity check in e2fsck's algorithm for finding a backup
2265 superblock, so that it won't accidentally find a superblock that was
2266 located in the journal, and then later reject it as being not a valid
2269 Fix e2fsck get_size logic so that it will work with the Linux floppy
2270 driver. The Linux floppy driver is a bit different from the other
2271 block device drivers, in that if the device has been opened with
2272 O_EXCL, it disallows another open(), even if the second open() does
2273 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2275 Fix error checking of badblock's last-block and start-block arguments.

2278 Fix e2fsck so that it doesn't overwrite the backup superblocks when
2279 recovering a journal until the master superblock has been confirmed as

2294 Fix e2fsck so that it updates the journal inode if it is corrupted and
2295 the backup journal information from the superblock was successfully
2296 used to recover the filesystem.
2298 Fix e2fsck so that it checks all of the blocks in the journal inode
2299 for validity. The original code only checked the direct blocks to
2300 make sure the journal inode was sane. Unfortunately, if some or all
2301 of the indirect or doubly indirect blocks were corrupted, this would

2306 Add extra sanity checks for extended attributes in the case where the
2307 size is zero but the offset is very large.
2309 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
2310 and ext2fs_get_next_inode_full().
2312 Clarify the copyright licenses used by the various libraries in
2313 the top-level COPYING file (Red Hat Bugzilla: 166058)
2315 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
2317 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
2319 Remove check in e2fsck which requires EA's in inodes to be sorted;
2320 they don't need to be sorted, and e2fsck was previously wrongly
2321 clearing unsorted EA's stored in the inode structure.
2323 Allow mke2fs or tune2fs to create a substantially larger journal (up
2324 to 10,240,000 blocks).
2326 Fix MD superblock detection, and make sure the correct UUID is
2327 reported from the MD superblock.
2329 Fix a signed vs. unsigned bug in debugfs.
2331 Enhance debugfs's date parser so that it accepts integer values.

2334 file with multiply claimed blocks is hard linked. or not at all if the
2335 root directory contains shared blocks
2337 Enhance debugfs so it can modify the block group descriptors using the
2338 command set_block_group_descriptor.

2361 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
2362 field on the first pass.
2364 Fix e2fsck to set the file type of the '..' entry when connecting
2365 a directory to lost+found. (Addresses Lustre Bug: #11645)
2367 Enhance e2fsck to recover directories whose modes field were corrupted
2368 to look like special files. This is probably only useful in
2369 artificial test cases, but it will be useful if we ever do the "inodes
2370 in directory" idea for ext4.
2372 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
2375 Fix resize2fs parsing of size parameter (in sector units). This was
2376 actually a bug in libe2p's parse_num_blocks() function. When handling
2377 the 's' suffix, it was ignoring the blocksize information passed in
2378 from the caller and always interpreting the number in terms of a 1k
2379 blocksize. (Addresses Debian Bug: #408298)
2381 There was a floating point precision error which could cause e2fsck to
2382 loop forever on really big filesystems with a large inode count.

2385 Fix memory leak in ext2fs_write_new_inode()
2387 Add support for using a scratch files directory to reduce e2fsck's
2388 emory utilization on really big filesystems. This uses the TDB
2389 library. See the [scratch_files] section of the e2fsck.conf man page
2392 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
2393 platform (Addresses Debian Bug: #397044)
2395 Add explanatory message to badblocks that -n and -w are mutually exclusive

2398 Allow debugfs and dumpe2fs to support fs features under development.
2400 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2401 ext2fs_open() , which allows application to open filesystes with features
2402 which are currently only partially supported by e2fsprogs.
2404 Allow unix_io to support offsets greater than 2G (Addresses
2405 SourceForge Bug: #1547922)
2407 Fixed overflow and signed/unsigned problems caused by the number of
2408 blocks or inodes exceeding 2**31 or being close to 2**32-1.
2410 Add support for unsigned directory hash calculations with hints in the
2411 superblock to fix cross-architectural portability for htree
2412 directories with filenames where the high 8th bit is set. (Addresses
2415 Fix resize2fs so that it gives user-intelligible error messages if the
2416 filesystem or the kernel does not support on-line resizing.

2419 Require mke2fs -F -F for really dangerous operations, since -F is
2420 needed for less dangerous operations such as creating filesystems
2421 images in regular files, or creating filesystems on whole block
2422 devices. These relatively innocuous usages should NOT be confused
2423 with running mke2fs on an apparently-mounted or in-use filesystem.
2425 Allow the default inode size to be specified into the mke2fs.conf
2428 Make the smallest default journal size is big enough so that on-line
2429 resizing should always work.

2460 Improve the (non-installed, for experts only) findsuper program by
2461 printing the uuid and label from the superblocks, as well as the
2462 starting and ending offsets of the filesystem given the information in
2463 the superblock. Omit by default printing superblocks that are likely
2464 found in located in an ext3 journal unless an explicit -j option is
2467 Updated Spanish, French and Dutch translations and added Catalan
2468 translation. (Addresses Debian bug: #411562)
2470 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2471 determining a partition's size, since binary searching to determine
2472 the device doesn't work on FreeBSD.
2474 Documentation about UUID's is available in enough places, and it's
2475 awkward to deal with debian-legal's insanities. So I'm caving in the
2476 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2477 don't have do the dfsg tarball. Also remove the rule that only tried
2478 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2479 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
2481 Fix the info-dir line so that the menu name does not contain a .info
2482 prefix. First of all, it's ugly, secondly, it causes the install-info
2483 command to fail to remove the com_err info file from the
2484 /usr/share/info/dir file when the comerr-dev package is removed and
2485 purged. (Addresses Debian Bug: #401711)

2498 E2fsck now supports the %It expansion when printing a problem report.
2499 It will print the type of the inode in the problem context.

2502 (Addresses Sourceforge Bug: #1565561)
2504 Remove unused variables and other lint/gcc -Wall cleanups
2506 Add check to ext2fs_get_device_size() so it will return EFBIG for for
2507 filesystems contained in regular files where the filesystem image size
2508 is returned by stat64().
2510 Set local environment variables to C so mk_cmds and compile_et always
2511 work. (Addresses SourceForge Bug: #1532177)
2513 Added the 64-bit byte swapping function ext2fs_swab64().
2515 Added two new helper functions to prevent 2**31/2**32-1 overflow
2516 problems: ext2fs_div_ceil() and e2p_percent().
2518 Create new ext2fs library inline functions ext2fs_group_first_block()
2519 and ext2fs_group_last_block() in order to calculate the starting and
2520 ending blocks in a block group.
2522 Create the generated files read-only to remind developers not to edit them.
2524 Add support for autoconf 2.60 (with backwards compatibility for older
2525 versions of autoconf).
2527 Added an "make rpm" target to top-level Makefile
2529 Added various FreeBSD portability fixes.
2531 Exclude mercurial files from the RPM build tree to speed up copy/build.
2533 Use root_sysconfdir to define the locations of mke2fs.conf and
2534 e2fsck.conf instead of using a hard-coded /etc pathname.
2536 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2538 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2540 If diff -u is supported, use it to report test failures.
2542 Updates/improvements to RPM spec file
2544 Add on-disk format definitions for the following new features:
2545 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2546 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2547 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2549 Add a new make target "checked-failed" in the tests directory which
2550 reruns any failed tests
2552 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2554 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2555 pointer dereferences, memory leaks, etc. None were security-criticial
2558 Fix up usage and decrement error messages in the test_icount program
2560 Add debugging code to the com_err library; if the environment variable
2561 COMERR_DEBUG is set to 1, print out debugging messages as error tables
2562 are added and removed from the com_err library. If the
2563 COMERR_DEBUG_FILE environment variable is set (and the process is not
2564 setuid) the debugging messages may be redirected to a file.
2566 Change all of the e2fsprogs programs to use the newer add_error_table()
2567 and remove_error_table() interfaces instead of the much older
2568 initialize_*_error_table() function.
2570 Add TDB support into the ext2fs library. This allows us to have a
2571 guaranteed library we can count on always being present so we can
2572 store data in an on-disk database.
2574 Add support for using TDB to store the icount data, so we don't run out
2575 of memory when checking really large filesystems.
2577 Change the regression test suite so that it skips empty test directories.
2579 Define the l_i_iversion field in ext2_inode. The l_i_version field is
2580 now defined from the old l_i_reserved1 field in the ext2 inode. This
2581 field will be used to store high 32 bits of the 64-bit inode version
2584 Add Makefile production rule for e2fsprogs.spec in case it gets
2587 Add new function profile_get_uint() to allow for a clean way to fetch
2588 unsigned integers from the context.
2590 Add test to make sure the ext2 superblock structure is 1024 bytes.
2592 Fix typo in name of f_dup4 regression test
2594 Add new function blkid_gc_cache() which performs a garbage collection
2595 pass on the /etc/blkid.tab file.
2597 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2598 general, only e2fsck (after the filesystem is clean), tune2fs, and
2599 resize2fs should change the backup superblocks by default. Most
2600 callers of ext2fs_open() should not be touching any superblock fields
2601 which require the backups to be touched.
2603 Add new function to libext2fs, ext2fs_default_journal_size(), which
2604 returns the default journal size.
2607 E2fsprogs 1.39 (May 29, 2006)
2608 =============================
2610 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2611 between 2**31 and 2**32 blocks.
2613 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2614 configure the filesystem features, blocksize, and inode_ratio for
2615 different filesystem types.
2617 Mke2fs will now create filesystems hash trees and on-line resizing
2618 enabled by default, based on the new /etc/mke2fs.conf file.
2620 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2621 filesystem device node in exclusive mode to prevent accidents by
2622 system administrators. In the case of resize2fs and mke2fs, it will
2623 only use exclusive mode if the filesystem is not mounted.
2625 Fixed a bug in mke2fs which caused it to to fail when creating the
2626 resize inode for large filesystems. (Addresses Debian Bug #346580)
2628 When allocating space for the RAID filesystems with the stride
2629 parameter, mke2fs will now place each portion of the group's inode
2630 table right up after the superblock (if present) in order to minimize
2631 fragmentation of the freespace.
2633 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2634 efficiently by writing the inode and block bitmaps in one pass, thus
2635 reducing the number of disk seeks required.
2637 Add support for on-line resizing to resize2fs.
2639 Fix blkid library so that logic to determine whether or not a device's
2640 cached information in /etc/blkid.tab needs to be verified or not
2641 doesn't get confused by a system clock which is insane (for example,
2642 if the battery is dead on a Macintosh running PPC Linux. (Addresses
2643 Red Hat Bug: #182188)
2645 The blkid library will now store the UUID of the external journal used
2646 by ext3 filesystems, so that in the future, the userspace mount binary
2647 can use this to find the location of the external journal and pass
2648 this information to the kernel.
2650 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2651 control how various options should be handled. See the e2fsck.conf
2652 man page for more details. (Addresses Debian Bug: #150295)
2654 E2fsck now prints an explanatory message when delaying a filesystem
2655 check when the system is running on battery. (Addresses Debian Bug:
2658 E2fsck will detect if the superblock's last mount field or last write
2659 field is in the future, and offer to fix if so. (Addresses Debian Bug
2660 #327580) These problems will be fixed automatically in preen mode
2661 since Debian's boot sequence bogusly doesn't set the time correctly
2662 until potentially very late in the bootup process, and this can cause
2663 false positives which will cause users' systems to fail to boot.
2664 (Addresses Debian Bugs #343662 and #343645)
2666 E2fsck now checks to see if the superblock hint for the location of
2667 the external journal is incorrect, and if so, offer to update it.
2668 (Addresses Debian Bug: #355644)
2670 Fix e2fsck from segfaulting on disconnected inodes that contain one or
2671 more extended attributes. (Addresses Debian Bug: #316736, #318463)
2673 E2fsck will stop and print a warning if the user tries running a
2674 read/write badblocks test on a read-only mounted root filesystem.
2676 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2677 C. Thompson for pointing these out; they were originally found using
2680 When resizing a file containing a filesystem, resize2fs will expand or
2681 truncate a file as necessary. (Addresses Debian Bug: #271607)
2683 Resize2fs will now automatically determine the RAID stride parameter that
2684 had been used to create the filesystem, and use that for newly created
2685 block groups. The RAID stride parameter may also be manually specified
2686 on the command line using the new -S option to resize2fs.
2688 Fix mke2fs so that it correctly creates external journals on
2689 big-endian machines (such as a S/390).
2691 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2692 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2693 Chambraud for pointing this out.)
2695 Dumpe2fs will now print the size of the journal (if present).
2697 Fix debugfs's set_inode_field command so it can properly set the frag,
2698 fsize, uid_high, gid_high, and author fields in the inode instead of
2699 silently failing, and so that setting the i_size actually sets i_size
2702 Add a new debugfs command, set_current_time, which sets fs->now so
2703 that regression test suites can repeatedly modify the filesystem's
2706 Fix a bug in debugfs's icheck which would incorrectly report the owner
2707 of an extended attribute block.
2709 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2710 print a usage message when an illegal option character is given.
2712 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2713 so it won't core dump. (Addresses SourceForge bug #1424311)
2715 Fix mklost+found so that it creates a full-sized directory on
2716 filesystems with larger block sizes.
2718 Fix a file descriptor leak in blkid library.
2720 Fix a display bug in "badblocks -sv" so that the done message properly
2721 clears the block number at the end of the test. (Addresses Debian Bug
2724 Allow fractional percentages to the -m option in mke2fs and tune2fs

2732 that the "best" (i.e., leaf) device is probed by the blkid library.
2734 Fix the blkid library so that it notices when an ext2 filesystem is
2737 Improve the blkid's library VFAT/FAT detection; it now understands
2738 labels stored in the root directory, and is more paranoid about
2739 checking the FAT superblock values.
2741 Fixed a fd leak in the uuid library which was causing problems for the
2742 LVM tools. (Addresses Debian Bug: #345832)
2744 Add support for the reiser4 and software suspend partitions to the
2745 blkid library. Also add support for extract the label from iso9660
2748 Fix a compile_et bug which miscount the number of error messages if
2749 continuations are used in the .et file.
2751 Add extra sanity checks to protect users from unusual cirucmstances
2752 where /etc/mtab may not be sane, by checking to see if the device is
2753 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
2756 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
2757 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
2759 Fix use-after-free bug in e2fsck when finishing up the use of the
2760 e2fsck context structure.

2780 Bugs: #360661, #360317)
2782 Fixed the Makefile so that they work correctly on newer versions of
2783 GNU make (i.e., 3.81).
2785 Add valgrind support to the regression test suites, and eliminate
2786 false positives from valgrind.
2788 Add a regression test suite for the blkid library.
2790 Fix a fencepost error in resize2fs caught by valgrind.
2792 Fix compiler warnings about missing memcpy prototypes.
2794 We no longer have the sparc assembly code in the header file any more,
2795 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2796 break compiles on the sparc architectures when using gcc.
2798 In the libext2fs library, add the new field fs->now which if non-zero
2799 is used instead of the system time when setting various filesystem
2800 fields (last modified time, last write time, etc.)
2802 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2803 ext2fs.h which is needed since the inline functions use memcpy().
2804 (Addresses Sourceforge Bug #1251062)
2806 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2807 the build system when building files in the util directory which are
2808 needed during the build process. This avoids potential problems when
2809 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2810 are not recognized as valid by the host compiler. (Addresses
2811 Sourceforge Bug #1261547)
2813 Clean up the blkid library by making the superblock and generic i/o
2814 functions to be more generic. Clean up interface to the probe
2815 function, and fix memory leak. Finallly, remove an unneeded reference
2816 to probe.h in the lib/blkid/resolve.c
2818 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2819 of invalid block #'s.
2821 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2822 indicate that the the function read/writes the memory location.
2824 Fix various gcc -Wall complaints.
2826 Add a dependency to make sure that the subdirectories are created
2827 before creating all of the object files, in order to address parallel
2828 build problem in the library Makefiles. (Addresses Sourceforge Bug:
2831 Add $(LDFLAGS) to the command line argument when generating an ELF or
2832 Solaris shared library, to allow cross-compile and other builds that
2833 might need to specify -L paths to needed libraries. (Addresses
2834 Sourceforge Bug #1261549)
2836 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2837 intended for testing purposes. It allows an ext2/ext3 developer to
2838 create very large filesystems using sparse files where most of the
2839 block groups are not initialized and so do not require much disk
2840 space. Eventually it could be used as a way of speeding up mke2fs and
2841 e2fsck for large filesystem, but that would be best done by adding an
2842 RO_COMPAT extension to the filesystem to allow the inode table to be
2843 lazily initialized on a per-block basis, instead of being entirely
2844 initialized or entirely unused on a per-blockgroup basis.
2846 Fix backwards compatibility so e2fsprogs will better compile on Linux
2849 Make test scripts more robust against locale-related environment variables
2851 Fix type warning problem with sizeof() in ext2fs_open2().
2853 Fix type warning problem with time_t in debugfs.
2856 E2fsprogs 1.38 (June 30, 2005)
2857 ==============================
2859 Fix blkid's test programs (built with "make check") compile correctly
2860 even without "configure --enable-blkid-debug".
2862 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2863 type aliasing rules on newer gcc compilers. (Addresses Red Hat
2866 Fix com_err library to make it more compatible with recent changes
2867 made to the com_err library in MIT Kerberos V5 version 1.4.
2868 (Addresses Sourcefroge Bug #1150146)
2870 General cleanup of messages printed by e2fsprogs programs for grammar,
2871 consistency, and to make life easier for translators. Fixed a few
2872 strings containing English that had not been marked as needing
2873 translations. Removed strings that do not need to be translated, to
2874 make life easier for translators.
2876 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2877 test to see if a device appears to be in use instead of just relying
2878 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
2880 Fix portability problem in the filefrag program affecting platforms
2881 where the size of an integer is smaller than the size of a long.
2882 (Addresses Debian Bug #309655)
2884 Mke2fs will now use a larger journal by default for filesystems
2885 greater than 4GB. (128 MB instead of 32MB).
2887 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2888 unless forced. This is to avoid signed vs. unsigned kernel bugs in
2889 block numbers that still need to be fixed.
2891 The blkid program has a new option which will more efficiently search
2892 for device when it is known (or expected) that only one matching
2893 device will be found in the system, such as when doing a lookup by
2896 Debian's e2fsprogs-specific initrd fragment will avoid including
2897 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2898 and LD_LIBRARY_PATH, and filtering out libraries found in
2899 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
2901 Fixed a potential portability issue in the blkid programs for
2902 architectures where the char type is unsigned. (Addresses Sourceforge
2905 Fix a bug in filefrag so that it doesn't falsely count an extra
2906 discontinuity when the first block found is an indirect block.
2907 (Addresses Debian Bug #307607).
2909 Fix blkid's recognition of cramfs filesystems, and enhance it to be
2910 able to handle cramfs labels.
2912 Fix debugfs's stat command to not core dump when a filesystem is not
2915 Fix e2fsck's handling of error conditions caused by the resize inode
2916 claiming blocks that are also used by other inodes, a filesystem
2917 corruption which was commonly caused by a bug in Fedora Core 3's
2920 Fixed bug in filefrag which caused it to fail on non-ext2/3
2921 filesystems. (Addresses Debian Bug: #303509)
2923 If the superblock last mount time indicates that the system clock may
2924 not be accurate, then e2fsck will omit checking inodes' deletion time
2925 field for indications of a potential corrupted orphaned inode list.
2926 (Previously e2fsck only ommited these LOW_DTIME checks when the
2927 superblock's last write time looked insane.)
2929 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
2930 (Addresses Debian bug #302200)
2932 Make the blkid library more paranoid about being run from setgid
2933 programs, and to use __secure_getenv() from libc if it is available.
2935 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2936 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
2937 and Sourceforge Bug: #1189803)
2939 Updated and fixed translations.
2941 Fixed various Debian packaging issues --- see debian/changelog for
2947 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2948 changed to take an unsigned int for the bit number. Negative bit
2949 numbers were never allowed (and didn't make any sense), so this should
2950 be a safe change. This is needed to allow safe use of block numbers
2951 greater than or equal to 2**31.
2953 The compile_et program will avoid recreating generated foo_err.c and
2954 foo_err.h files if no changes are necessary. The compile_et program
2955 will also atomically replace these files to avoid a potential parallel
2956 build race problem on SMP systems. (Addresses Sourceforge Bug:
2959 Added a new function to the blkid library, blkid_probe_all_new(),
2960 which only probes newly added disk devices, and change
2961 blkid_find_dev_with_tag() to use this function so that when a
2962 requested tag is not found, devices that were previously not checked
2963 are searched before searching all devices in the system.
2965 Added new functions to the blkid library, blkid_dev_set_search() and
2966 blkid_dev_has_tag().
2968 E2fsck's problem strings can now use @m and @n as abbrevations for
2969 "multiply-claimed" and "invalid", respectively.
2971 The e2fsprog.pot file now has an explanation of how the @-expansion
2972 and %-expansion works, and strings in e2fsck/problem.c which contain @
2973 characters now have comments in e2fsprogs.pot with the @-expansion to
2974 make life easier for translators.
2976 Fixed missing return values in the ext2fs library which could cause it
2977 to return random garbage in certain error conditions.
2979 Allow the current time to be overriden via the E2FSCK_TIME environment
2980 variable for use in regression tests.
2982 The test scrpit driver program now exits with a non-zero status if
2983 there any of its test that it ran failed.
2985 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
2988 Fixed "make check" so that it compiles correctly even when e2fsprogs'
2989 header files have not be installed in the system include directories.
2990 (Addresses Sourceforge Bug: #1180572)
2992 Fixed gcc -Wall nits.
2995 E2fsprogs 1.37 (March 21, 2005)
2996 ===============================
2998 Add support for checking the validity of Extended Attributes stored in
3001 Add support for dumping the contents of large inodes to debugfs,
3002 including the extended attributes stored in inodes.
3004 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3005 when we create a new inode we make sure that the extra information in
3006 the inode (any extra fields in a large inode and any ea-in-inode
3007 information) is initialized correctly. This can take place when
3008 mke2fs creates the root and lost+found directory, when e2fsck creates
3009 a new root inode or a new lost+found directory, and when the user uses
3010 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3011 create inode could inherit garbage (or old EA information) from a
3012 previously deleted inode.
3014 Fixed a bug in e2fsck so it would notice if a file with an extended
3015 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3018 Added support to filefrag to detect files which are using the new
3019 experimental file extents format, and use the non-ext2 algorithm in
3020 that case. Fixed a bug to avoid reporting a false discontinuity if
3021 there is one or more unallocated blocks at the beginning of a file.
3023 Duplicated a check for noticing whether or not the number of blocks
3024 (given a certain blocksize) is greater than 2**32 when the
3025 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3026 allows mke2fs to automatically use a larger blocksize when creating a
3027 filesystem on a very large device when run on systems that do not
3028 support BLKGETSIZE64.
3030 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3031 build system had been switched to treat the .gmo files as shipped
3032 files (for backwards compatibility with systems that have older GNU
3033 I18N tools installed), but the gen_tarball.in script was still
3034 removing the .gmo files from the official source distribution.
3036 Fixed various Debian packaging issues --- see debian/changelog for
3037 details. (Addresses Debian Bugs ##296769, #299341)
3042 Added new functions to the e2p library which convert between a string
3043 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3044 make the generated binaries more compact.
3046 Fixed a compile-time error on Darwin systems.
3048 Cleaned up the lib/ext2fs Makefile slightly.
3051 E2fsprogs 1.36 (February 4, 2005)
3052 =================================
3054 All of the patches that were applied to Fedore Core 3's
3055 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3056 lot of bug fixes first. Users of Fedora Core 3 are strongly
3057 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3059 Add support for filesystem with the online resizing via resize inode
3060 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3061 patches also didn't bother to do any consistency checking on the
3062 resize inode, or add any tests to the regression test suite. The "-R
3063 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3064 being listed in mke2fs's usage message. All of these shortcomings
3065 have been corrected.
3067 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3068 program. In order to do this, the user must run the commands:
3070 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3071 e2fsck -f /dev/hdXXX
3073 Optionally, the ext2prepare command can be used to re-enable online
3074 resizing after the filesystem has been fixed.
3076 The fsck program will now accept an optional filedescriptor argument
3077 to the -C option. (The Fedora version of this patch would sometimes
3078 cause fsck to ignore a parameter on fsck's command line in some rare
3081 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3084 Make sure resize2fs releases the blocks belonging to the old inode
3085 table blocks when moving the inode table. (Addresses Debian Bug:
3088 Skip the r_resize_inode test if resize2fs is not compiled (due to
3089 configure --disable-resizer)
3091 E2fsck now checks the summary filesystem accounting information, and
3092 if any of the information is obviously wrong, it will force a full
3093 filesystem check. (Addresses Debian Bug #291571)
3095 Fix e2fsck to not complain when the resize_inode feature is enabled,
3096 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3099 Fix e2fsck to note delete symlinks that contain an extended attribute
3100 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3103 Add new utility program, copy_sparse.c, which is very useful
3104 for dealing with large sparse files (such as e2image files).
3106 Add support for jnl_blocks[] for debugfs's set_super_value.
3108 Fix filefrag so that it works correctly with sparse files.
3110 Filefrag -v will print first and last blocks.
3112 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3115 Add mke2fs support so that it can support filesystems larger than 4TB
3116 automatically, by retrying with a 4k blocksize if the device size is
3117 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3120 Change blkid to test for NTFS first because Windows sometimes doesn't
3121 clear enough of the parition to confuse the probing routines into
3122 thinking the old filesystem type is still valid. (Addresses Debian
3125 Add support for swap partition label and uuid's in the blkid library.
3127 Add support to the blkid library to recognize Oracle ASM volumes.
3129 Make blkid -t display all devices that match the specified criteria,
3130 not just the first one, and work more consistently when the blkid
3131 cache file is not available or set to /dev/null. (Addresses Debian
3132 Bug #290530 and #292425)
3134 Badblocks will now correctly display block numbers greater than
3135 999,999,999 in its progress display.
3137 The tune2fs program will not allow the user from setting a ridiculous
3138 number of reserved blocks which would cause e2fsck to assume the
3139 superblock was corrupt. E2fsck's standards for what is a ridiculous
3140 number of reserved block has also been relaxed to 50% of the blocks in
3143 The blkid library will return vfat in preference to msdos, and ext3 in
3144 preference to ext2 (if the journalling flag is set) so that mount will
3145 do the right thing. (Addresses Debian bug #287455)
3147 Mke2fs will now use the -E option for extended options; the old -R
3148 (raid options) option is still accepted for backwards compatibility.
3149 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3151 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3152 (via "32m" or "4g" on the command line) if the user finds this more
3153 convenient than specifying a block count.
3155 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3156 cache conherency problem.
3158 Debugfs now supports a new command, set_inode_field, which allows a
3159 user to manually set a specific inode field more conveniently, as well
3160 as set entries in the indirect block map.
3162 Debugfs's set_super_value command has been enhanced so that the user
3163 can set most superblock fields, including the date/time fields and
3164 some of the more newsly added superblock fields.
3166 E2fsprogs programs now accept an offset to be passed to the file
3167 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3169 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3170 support on the x86 doesn't exist for now, but it can be useful on
3171 other architectures with page sizes greater than 4k. There are 2.6
3172 kernel patches out there which enable this, but they are of this
3173 writing still experimental.
3175 The e2image command now takes the -s option which will scramble
3176 directory entries for raw image files.
3178 Fix a file descriptor leak in the filefrag program.
3180 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3183 Fix bug in debugfs where kill_file would lead to errors when deleting
3184 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3186 Fix bug in the blkid library when detecting the ocfs1 filesystem
3188 Remove obsolete EVMS 1.x and a.out DLL support.
3190 E2fsck will attempt to recover from a journal containing illegal blocks.
3192 Fixed two potential ordering constraint problems in e2fsck which might
3193 cause the filesystem to be corrupted if e2fsck is interrupted during a
3194 (extremely narrow) race window. Thanks to Junfeng Yang from the
3195 Stanford Metacompilation group for pointing this out.
3197 Fixed bug in e2fsck where it would not accurately detect whether or
3198 not the system is running on adaptor if the ACPI device representing
3199 the AC adapter didn't correspond to the what was used on IBM
3202 Change e2fsck to accept directories greater than 32MB.
3204 Fix e2fsck so that a checkinterval of zero disables a time-based check
3207 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3208 to the PAGER environment variable. (Addresses Debian Bug #239547)
3210 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3213 The debugfs program will set the filetype information when creating a
3216 Add debugfs -d option to use a separate source of data blocks when
3217 reading from an e2image file.
3219 Add e2image -I option which allows the e2image metadata to be
3220 installed into a filesystem.
3222 Fixed bug in the badblocks program which caused "done" to always
3223 appear in english even when a translation was available. (Addresses
3226 The blkid program has a new option -o which controls the output format
3227 of the blkid program; this is makes blkid more convenient to use in
3230 Fix a minor bug in uuid library, which was not using the full 14 bits
3231 of clock sequence when generating UUID's.
3233 Fix a Y8.8888K problem in the uuid library.
3235 Logsave now creates a new session id for itself to avoid getting
3236 killed by init whan transitioning between init levels.
3238 Change the licensing of the UUID library to be the 3-clause BSD-style
3239 license; this allows Apple to use the uuid library in Darwin.
3241 Add ocfs and ocfs2 probe support into the blkid library.
3243 Fix a memory and file descriptor leak in the blkid library.
3245 The blkid library will revalidate the device if the system time is
3246 earlier than last verification time of the device, since that
3247 indicates that the system time is probably nottrustworthy.
3249 The blkid library will override the default location of the blkid.tab
3250 file by the BLKID_FILE environment variable, if it is available.
3252 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3254 Add various portability fixes for lame new versions of glibc, Darwin
3255 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3256 Bugs #239934, #264630, #269044, #255589, #289133)
3258 Add support for Windows 9x/NT under Cygwin.
3260 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3261 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3263 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3265 Update the rpm spec files so that it works better with Fedora core 2
3268 Fixed various Debian packaging issues (see debian/changelog). In
3269 particular, fixed the Debian initrd scripts. (#241183, #248050,
3276 Fixed various gcc -Wall warnings.
3278 The uuid library now has new functions uuid_unparse_upper() and
3279 uuid_unparse_lower() which forces the case of the hex digits to be
3280 upper case, or lower case.
3282 The build process has been speeded up by enhancing the subst program
3283 to update the modtime on the generated files even when the generated
3284 file hasn't changed.
3286 The uuid library now uses C99 stdint.h types instead of custom types.
3288 Updated config.guess and config.sub with newer versions from the FSF.
3290 Removed out of date .cvsignore files from the source distribution.
3292 The ext2fs_unlink() function will return an error if both the name and
3293 inode number are unspecified, to avoid doing something surprising
3294 (such as unconditionally deleting the first directory entry).
3295 Directory entries are now deleted by coalescing them with the previous
3296 directory entry if possible, to avoid directory fragmentation. This
3297 is not an issue with the e2fsprogs suite, but may be a problem for
3298 some of the users of libext2fs, such as e2tools.
3300 Add support for version numbers of the form "1.36-rc1".
3302 Fix build of mke2fs.static.
3304 Add basic ext2fs library support for large (EA in inode) inodes.
3306 The test_io mechanism can now abort after n reads or writes to a
3307 particular block. The block is specified by TEST_IO_BLOCK environment
3308 variable, and the read/write count by the TEST_IO_READ_ABORT and
3309 TEST_IO_WRITE_ABORT environment variables. The block data is now only
3310 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3312 UUID_DEFINE() in the uuid library now creates a static variable, with
3313 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3314 be used in header files.
3316 Add support for the install-strip and install-shlibs-strip targets, as
3317 suggested by the GNU coding guielines. "make install" no longer
3318 strips the binaries which are installed.
3320 Remove support for the --enable-old-bitops configure option which was
3321 only for very old sparc systems.
3323 Remove support for --enable-clear-htree; this was only needed during
3324 the early development of the htree patch.
3326 Use Linux-kernel-style makefile output so it is easier to see compiler
3329 Update gettext files to version 0.14.1.
3331 Update to use autoconf 2.5x.
3333 Improved support for compiling e2fsprogs under dietlibc.
3335 Make e2fsprogs portable to Solaris and FreeBSD systems.
3337 Add blkid_verify(), blkid_get_library_version(), and
3338 blkid_parse_version_string() functions to the blkid library.
3340 Add pkg-config files for e2fsprogs's libraries.
3342 Fix "make uninstall" to so that it removes everything that is installed.
3344 Add a configure --enable-maintainer-mode option which enables the
3345 makefile rules to rebuild the configure script from configure.in, and
3346 to reubuild the .gmo files in po directory.
3348 Drop the sparc assembly bitwise operations; it's less efficient
3349 than the GCC 3.4 compile code and triggers compiler warnings on
3350 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

3354 E2fsprogs 1.35 (February 28, 2004)
3355 ==================================
3357 E2fsck has a new -k option, which in conjunction with the -c options,
3358 preserves the existing badblocks list.
3360 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3362 E2fsprogs will now deal correctly with symlinks that contain
3363 extended attribute information, which can be created using SE Linux.
3364 (Addresses Debian Bug #232328)
3366 Remove a double longjump into an invalid stack frame bug in e2fsck.
3367 (This was during an abort sequence, which normally worked on Linux and
3368 caused a core dump on other operating systems.)
3370 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3371 (the NLS library will replace "" with the .po header information).
3373 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3374 dump due to a division by zero error. (Addresses Debian bug #207082)
3376 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3377 when reconnecting a directory requires creating a lost+found
3378 directory. (Addresses Debian bug #219640).
3380 Fixed a bug where e2fsck would bomb out if a journal needed to be
3381 replayed when using an alternate superblock.
3383 E2fsck will give an extra grace period before actually forcing a check
3384 if the laptop is running on battery. The next time fsck runs while
3385 the system is on the AC mains, or after the grace period is exceeded,
3386 the filesystem will be checked. (Addresses Debian bug #205177)
3388 E2fsck will inform the user when there are 5 or fewer mounts before a
3389 filesystem check will be forced. (Addresses Debian bug #157194)
3391 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3392 We now correctly handle the case where there is an overlap between a
3393 block group descriptor or a superblock and a bad block indirect block.
3394 In the case where the indirect block is corrupted, we now suggest
3397 Fix byte swap bugs in e2fsck that caused the journal backup location
3398 in the superblock and symlinks created by SE Linux to be cleared
3399 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
3401 E2fsck -c now replaces the current list of bad blocks with the ones
3404 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3405 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3407 Fix a potential bug in e2fsck which could cause it to core dump when
3408 trying to print the location of the backup superblock.
3410 Protect against a potential core dump in e2fsck when printing a
3411 message about backup superblocks.
3413 Add support for backing up the journal inode location in the
3414 superblock. E2fsck will automatically save the journal information in
3415 the superblock if it is not there already, and will use it if the
3416 journal inode appears to be corrupted. ext2fs_add_journal_inode()
3417 will also save the backup information, so that new filesystems created
3418 by mke2fs and filesystems that have journals added via tune2fs will
3419 also have journal location written to the superblock as well.
3420 Debugfs's logdump command has been enhanced so that it can use the
3421 journal information in the superblock.
3423 E2fsck will now update all superblocks when moving the journal inode.
3425 Shrink the size of the e2fsck executable by moving some initialized
3426 variables to the BSS segment.
3428 E2fsck will avoid printing the ^A and ^B characters which bracket the
3429 progress bar when stdout and stdin are a tty device instead of a pipe
3430 to another program. (Addresses Debian bug #204137)
3432 Debugfs's mkdir command will automatically expand the directory if
3433 necessary. (Addresses Debian Bug: #217892)
3435 Fixed a bug in debugfs so that copying a file from /dev/null uses the
3436 correct mode bits. (Addresses Debian Bug: #217456)
3438 If the environment variables DEBUFS_PAGER and PAGER are not set,
3439 debugfs now searches for the appropriate pager to use, beginning with
3440 /usr/bin/pager, and then falling back to 'more' and 'less'.
3441 (Addresses Debian bug #221977)
3443 Debugfs will now support 2.6 device numbers where the major or minor
3444 number may be larger than 255. (Addresses Sourceforge bug #865289)
3446 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
3448 Chattr now stops processing options when it sees '--'. (Addresses
3451 Fix regression tests so they work correctly when e2fsprogs is compiled
3452 with configure --disable-htree.
3454 Fix bug in uuid library when there is no network card and the library
3455 is generating a time-based uuid. The random MAC address was not
3456 correctly generated to be a multicast address.
3458 Add compile_et extensions from Heimdall that were missed the first time
3461 Fix bug in badblocks when using O_DIRECT; we need to make sure that
3462 we're reading from an offset which is page aligned. For read-only and
3463 read-write tests, we try to recover after an error so that we can
3464 continue reading on page-aligned boundaries. (Addresses Debian Bug

3487 Centralize code which calculates the location of the superblock
3488 and block group descriptors so that it is in a single library routine.
3490 Added two new functions, ext2fs_file_open2() and
3491 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3493 Fix compile_et to output the correct prototype for
3494 initialize_xxx_err_table_r() in the header file. (Addresses Debian
3497 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3499 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3500 present. This is for when we try stuffing an int into void * pointer.
3502 Fix type-punning which can cause gcc 3.x to miscompile code by getting
3503 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3504 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3505 **'. The EVMS code uses an ugly union approach since we don't want to
3506 modify the EVMS interfaces.
3508 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3509 aid build process on systems can use invoke GNU make as "gmake".
3511 Added regression testing for mke2fs.
3513 Fixed gcc -Wall nitpicks.
3515 Fixed various compiler warnings.
3517 Add portability fixes for FreeBSD and for using fsctl under Darwin to
3518 support ext2 ioctl's.
3521 E2fsprogs 1.34 (July 25, 2003)
3522 ===============================
3524 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3525 a tight loop while waiting for a child fsck to exit in some cases.
3526 This burns CPU times which slows down the low-level filesystem check.
3528 Added code to mke2fs to assure that the default block size for a
3529 filesystem is at least as big as the sector size of the device, if it
3532 Changed mke2fs and resize2fs to round the default size of a filesystem
3533 to be an even multiple of the VM pagesize in order to avoid a Linux
3534 kernel bug introduced when the storage of the buffer cache was moved
3535 into the page cache.
3537 Mke2fs will warn the user when creating a filesystem with journaling
3538 and a blocksize greater than 4096. (Addresses Debian bug #193773)
3540 Fixed a bug in resize2fs which caused it to fail on filesystems with a
3541 non-empty bad block list. Resize2fs now discards any blocks on the
3542 badblock list which are no longer part of the filesystem as the result
3543 of a filesystem shrink. (Note: this means that shrinking and then
3544 enlarging a filesystem is no longer a reversible operation;
3545 information about bad blocks in the part of the filesystem which is to
3546 be chopped off will be lost.)
3548 Changed resize2fs so the user can use prefixes to specify the units of
3549 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3550 and to make the error and informational messages explicitly display
3551 the blocksize used by the filesystem, in order to avoid confusion.
3552 (Addresses Debian bug: #189814)
3554 Added a new debugfs command, dump_unused, which dumps the contents of
3555 all unused blocks to stdout. (Useful as an emergency try-to-find
3556 deleted data command.)
3558 Added a new debugfs command, imap, which prints the location of a
3559 specified inode in the inode table.
3561 Fixed a bug in the badblocks program which caused it to use one bit of
3562 randomness in its non-destructive read/write test, instead of using a
3563 full 8 bits of randomness.
3565 Added a new option (-t) to badblocks, which allows the user to control
3566 the test pattern(s) used when checking a disk.
3568 The blkid probe function now more correctly detects UDF filesystems.
3570 Fixed a bug in the blkid library which caused it to not update its
3571 cache if a filesystem changes from having a label to not having a
3574 Fixed a bug in the blkid library wihch could avoid an infinite loop
3575 in blkid_find_dev_with_tag() if /proc is not mounted and there the
3576 /etc/blkid.tab file has not yet been created.
3578 Fixed the badblocks program so that the destructive read/write test
3579 honors the -c option, and to use O_DIRECT when possible to avoid
3580 thrashing the system block buffer cache.
3582 Fixed various NLS issues.
3583 - Added Czech and Swedish translations
3584 - Removed testing NYC translation
3585 - Fixed NLS support for message abbrevations in e2fsck
3586 - Remove de-utf.po, since we shouldn't have two versions using different
3588 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3589 simplify the statistics reporting in e2fsck.
3591 Changed configure.in so that its defaults for *BSD systems no longer
3592 build an fsck wrapper, and not to install in /usr/local by default.
3594 Fixed some minor spelling errors/typo's in e2fsck and the configure
3597 Fixed various Debian packaging issues (see debian/changelog).
3599 Updated and clarified man pages. (Addresses Debian Bug #195616)
3604 Fix gcc -Wall nitpicks.
3606 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3607 NLS support by default. (Added partial workaround for gettext/Darwin
3608 incompatibility problems.)
3610 Added full MIT KRB5 and Himdall compaibility support to the com_err
3611 library and the compile_et program. (Addresses Debian bug #191900)
3613 Added the blkid_known_fstype() function to the blkid library, which
3614 returns true if it is passed a filesystem type which is recognized by
3615 the blkid probing functions.
3617 Improved the documentation for the blkid library.
3619 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3620 returns the hardware sector size of a device, if it is available.
3622 Added a dependency in the blkid library's .so file to the uuid
3623 library, since the former uses the latter. (Addresses Debian bug
3626 Added --with-diet-libc and --disable-evms to the configure script.
3628 Fixed a minor memory leak in the badblocks program.
3630 Fixed a portability problem in tune2fs --- not all systems have strptime().
3632 Fixed a portability problem in debugfs with the use of getopt() more
3633 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3636 Add support Windows support to ext2fs_get_device_size().
3638 Added (normally disabled) debugging code to the Unix I/O manager which
3639 causes it to disable all userspace caching if the NO_IO_CACHE is
3642 Changed the test I/O manager so it can always be linked into e2fsck,
3643 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3644 configure script. The test I/O manager will only print any debugging
3645 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3646 variables are set, which specifies which I/O operations are logged and
3647 a block number to watch, respectively. The log messages are sent to
3648 stderr by default, unless a filename is specified via the
3649 TEST_IO_LOGFILE environment variable.
3652 E2fsprogs 1.33 (April 21, 2003)
3653 ===============================
3655 Added a new utility program, logsave, which captures the output of a
3656 command in a log file, even if the containing directory hasn't been
3657 mounted yet (in which case the it saves the output in memory until it
3658 can write out the logfile). This is useful for capturing the
3659 output of fsck during the boot sequence.
3661 Fixed some portability problems that were causing problems under
3662 the Cygwin32 environment.
3664 Mke2fs now interprets a negative number to the -b option as a minimum
3667 Fixed a bug in mke2fs which was incorrectly checking the argument to
3668 the -g option if the default block size was used. (Addresses Debian
3671 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3672 it can not find filesystem checkers for jfs, reseirfs, and xfs.
3674 E2fsck now updates the global free block and inode counters from the
3675 block group specific counters quietly. This is needed for an
3676 experimental patch which eliminates locking the entire filesystem when
3677 allocating blocks or inodes; if the filesystem is not unmounted
3678 cleanly, the global counts may not be accurate.
3680 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3681 2.0 is not yet supported; this only pulled in the bug fixes: fixed
3682 possible hangs caused by bugs in calling waitpid, and not setting the
3683 pipe to non-blocking mode; also fixed a file descriptor leak; made
3684 sure all functions call log entry/exit functions.)
3686 Badblocks now flushes its output file as bad blocks are discovered.
3688 The uuid library is now more paranoid about assuming the correctness
3689 of the /dev/random device; it mixes in a stream of bytes from
3690 random/srandom, just in case.
3692 Update Debian files to reflect the fact that I am now the Debian
3693 maintainer of e2fsprogs. Other various Debian-specific packaging
3696 Move the source tarball generation functions from the top-level
3697 makefile to the util/gen-tarball script.
3699 Updated the Turkish .po translation file.
3701 Added Heimdal and MIT krb5 extensions to the com_err library to make
3702 it more compatible with com_err libraries from those distributions.
3704 Changed dumpe2fs to always display the superblock fields relating to
3705 the journalling and/or directory indexing feature even if those
3706 features are not enabled.
3708 Updated and clarify copyright statement vis-a-vis alpha releases of
3711 The ss library will now try to dynamically link to the readline
3712 library and use it if it is present in the system. This means that
3713 the debugfs program now has line editing and history features. The
3714 SS_READLINE_PATH environment variable is used to find a readline or
3715 readline-compatible library.
3717 E2fsck now finds most duplicate filenames (all when rebuilding all
3718 directories via the -D option) and offers to delete or rename
3719 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3721 Fix bug in e2image. When writing out a raw image file, include data
3722 blocks from symlinks that do not store the symlink within the inode.
3724 Fix bug in resize2fs which incorrectly moved the block and inode
3725 bitmaps for sparse superblock filesystems and incorrectly marked
3726 blocks as in use. (Addresses Debian bug #174766)
3728 Added a new shared library, the blkid library, which efficiently
3729 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3730 and UUID filesystem specifiers without needing to search all of the
3731 devices in the system. Instead, the device is looked up in a cache
3732 file, and then verified to make sure the blkid cache is correct.
3734 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3735 the device name, using the blkid library. (Addresses Debian bugs
3738 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3739 used for spaces in device labels.
3741 Removed 32-bit limitations for debugfs's dump command.
3743 If the user specifies a large number of inodes, Mke2fs will
3744 automatically adjust the number of blocks per group to find a valid
3745 set of filesystem parameters.
3747 Add workaround to detect broken MD devices where when some of the
3748 underlying devices are marked read-only, writes to the MD device are
3749 silently dropped. E2fsck will detect if there is an attempt to run
3750 the journal twice, and abort with an error if this is the case.
3751 (Addresses IBM Bugzilla bug #1226)
3753 E2fsck will print an error if more than one of the -p/-a, -n or -y
3754 options are specified.
3756 E2fsck will fix HTREE corruptions in preen mode, without stopping the
3757 boot process. This is needed because the 2.4 ext2 filesystem
3758 accidentally had the INDEX_FL backwards compatibility code removed.
3760 Mke2fs no longer creates filesystems with the dir_index flag set by
3761 default; the user has to specifically request it.
3763 Update and clarified various man pages. (Addresses Debian bugs
3764 #173612, #175233, #175113, and #170497, #185945, #188318)
3766 Created man page for the mk_cmds program (from the libss library).
3771 Fix various gcc -Wall nits.
3773 Fixed a lot of portability problems that caused e2fsprogs not to build
3774 successfully under Solaris and Apple/Darwin.
3776 Fixed a Makefile dependency to allow building e2fsprogs using parallel
3779 Changes to create a subset distribution which consists only of the
3780 et, ss, uuid, and blkid libraries. The configure script and top-level
3781 makefile were changed to support working with a subset distribution.
3783 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3784 actually used, and might people who are looking for
3785 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3787 Updated debian files to fix a number of Lintian warnings.
3789 Updated config.guess and config.sub with newer versions from the FSF.
3791 Removed unnecessary libraries from being linked into the fsck, lsattr,
3792 chattr, and blkid executables.
3794 E2fsprogs 1.32 (Nomvember 9, 2002)
3795 ==================================
3797 Fixed a bug in the Unix I/O routines which caused needless writebacks
3798 of clean blocks from the unix_io cache (they were erroneously marked
3799 as being dirty, so they were getting written back to disk before
3800 getting evicted from the disk cache). This was harmless, but it
3801 significantly slowed down e2fsck.
3803 Made some other minor optimizations to the Unix I/O routines to save a
3804 small amount of CPU time.
3806 Updated internationalization files.
3809 E2fsprogs 1.31 (Nomvember 8, 2002)
3810 ==================================
3812 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3813 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3814 handling for child process that die unexpectly. Add a hack to force
3815 mkfs to create filesystems that won't cause problems with hardware
3816 that has 2k or 4k minimum blocksize requirements. Read from child
3817 processes in non-blocking mode, so that the GUI continues to update.
3819 Fix e2fsck so that it returns the appropriate exit code when the root
3820 filesystem has been changed, so that system's rc scripts will be told that
3821 the system needs to be rebooted.
3823 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3824 was set, some of the descriptor blocks that should have been written
3825 out were getting skipped.
3827 Changed e2fsck to force out changes to the backup copies of the
3828 superblock and block group descriptors when important changes are made
3829 to those data structures.
3831 Fix a bug where e2fsck could erroneously mark a filesystem as being
3832 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3833 introduced in e2fsprogs 1.28.)
3835 If journal debuging is enabled using --enable-jbd-debug, the debugging
3836 level is now set via the E2FSCK_JBD_DEBUG environment variable.
3838 If byteswapping support is disabled using configure --disable-swapfs,
3839 skip the tests which depend on byte-swapping, so that "make check"
3842 Lshattr will now display the indexed directory flag. Also, some of
3843 the more esoteric compression flags are supressed unless compression
3844 support has been enabled.
3849 E2fsprogs 1.30 (October 31, 2002)
3850 =================================
3852 When resizing a filesystem, and inodes need to moved, resize2fs will
3853 update the inode's ctime field, and the mtime field of the containing
3854 directories, so that incremental backups using dump/restore will work
3857 In order to avoid spurious errors, e2fsck wil check the last
3858 superblock write time to determine whether or not it can safely use
3859 the LOW_DTIME checks to determine if there are inodes on the orphan
3860 inode linked list that had somehow gotten disconnected. (Addresses
3861 Sourceforge bug #620980)
3863 Partition in /proc/partitions that being with the string "lvm" are
3864 considered real partitions even if they do not end with a number.
3866 Fixed a bug in the the uuid generation function, where if /dev/urandom
3867 is not present, but /dev/random is, and there isn't sufficient
3868 entropy, the get_random_byte function could spin a loop forever.
3870 E2fsck, mke2fs, etc. will now reliably notice when image files are
3871 mounted using the loopback interface. (Addresses Sourceforge bug
3874 When flushing buffers (as is done by badblocks, for example) check to
3875 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3876 FDFLUSH ioctl which causes the MD device driver which causes confusing
3877 syslog messages about obselete ioctl messages. (Addresses Sourceforge
3880 Debugfs's write command now checks to see if the destination filename
3881 exists before creating it. (Addresses Sourceforge bug #478195.)
3883 When installing man pages, search for compressed man pages using all
3884 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3886 Fixed a bug in fsck where multiple filesystems specified on the
3887 command were not being checked in parallel due to a logic bug
3888 introduced to support the FSCK_MAX_INST environment variable.
3890 We have added a new superblock field, s_mkfs_time, which indicates
3891 when a filesystem was created. It is set via mke2fs, and printed out
3892 by dumpe2fs, but is not actually touched by the kernel.
3894 Dumpe2fs has been made more robust by not aborting if there is an
3895 error reading the block/inode bitmaps; instead it will still print out
3896 the location of the block/inode bitmaps and inode table.
3898 Add support for the an alternative block group descriptor layout which
3899 allows for on-line resizing without needing to prepare the filesystem
3900 in advance. (This is the incomat feature flag meta_bg.)
3902 Add support for storing default mount options in the superblock, so
3903 that the filesystem can be mounted with specific mount options without
3904 needing to specify them on the mount command line or in the /etc/fstab
3907 Add support for a new inode flag, which is to be used for indicating
3908 the top of directory hierarchies for the Orlov block allocator.
3910 Fix e2fsck so that if it creates the lost+found directory, it does so
3911 with the more apporpriate permissions of 0700. Also change
3912 mklost+found so that it also creates the directory 0700.
3914 Fixed format bug in e2fsck if NLS is in use.
3916 Add a German translation for e2fsprogs's NLS support.
3918 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3919 the beginning of the inode table. This won't matter much, since if
3920 there is a bad block at the beginning of the inode table, the root
3921 directory won't be available. But at least e2fsck won't crash in this
3924 Fixed endian problems in the htree code for e2fsck and debugfs.
3926 When byte-swapping a filesystem on a PPC architecture, byte-swap the
3927 bitmaps since the historical big-endian ext2 variant had byte-swapped
3928 bitmaps, and the ext2fs library assumes this. This fixes the
3929 regression test suite on PPC machines.
3931 Fix e2image so that it handles a bad block in the inode table
3934 E2fsck now uses a more sophisticated algorithm to salvage corrupted
3935 directories that recovers more information in the corrupted directory
3938 E2fsck now performs additional consistency checks on indexed (HTREE)
3941 Fix bug where efsck might get confused about whether a completely
3942 empty directory block is an empty leaf block or an interior htree
3943 node. This could cause e2fsck to get confused into think that a valid
3944 indexed directory was corrupted.
3946 E2fsck no longer creates an empty directory entry at the end of a
3947 directory block when optimizing a directory. This would cause some
3948 earlier versions of the dxdir kernel code to corrupt the directory
3949 when attempting to split a node containing an empty directory entry.
3951 E2fsck could sometimes in rare circumstances leave the indexed flag
3952 set after a small directory was optimized by compressing it instead of
3953 indexing it. (This should never happen in real life, since
3954 directories that small wouldn't have been indexed, but better safe
3957 E2fsck now only updates the master superblock in all cases. This
3958 slightly shortens its run time.
3960 Ext2ed can deal with directory entries of length 0; previously it
3961 would get stuck in an infinite loop.
3963 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3964 specifiers. (Sourceforge patch #613447)
3966 Badblocks will now work correctly on read-only devices such as
3967 CD-ROM's. (Sourceforge patch #600451)
3969 Updated and clarified man pages. (Addresses Debian bug #167108)
3972 E2fsprogs 1.29 (September 24, 2002)
3973 ===================================
3975 Fixed a bug in e2fsck which could corrupt a directory when optimizing
3976 it (via the -D option) or rebuiliding the hash tree index with a 1 in
3977 512 probability, due to a fence post error.
3979 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
3982 Mke2fs now enables the directory indexing flag by default. (Since
3983 this is a compatible feature flag, it's safe to do so.)
3985 Tune2fs will support setting the directory indexing feature flag. It
3986 will automatically set up the default hash algorithm and hash seed
3987 fields in the superblock.
3989 If the bone-headed user enters the root filesystem twice in
3990 /etc/fstab, the -R option which skips the root filesystem will skip
3991 all of them. (Addresses Debian bug #159423). Note! This is not a
3992 precedent for dealing intelligently with any other kind of doubled
3993 entry in /etc/fstab!
3999 Removed perror declaration in lib/et/internal.h. All modern systems
4000 can be expected to define perror() these days. Besides, the lib/et
4001 code wasn't using perror at all anyway. :-)
4004 E2fsprogs 1.28 (August 31, 2002)
4005 ================================
4007 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4008 for setting the htree flag is not included yet, although it can be
4009 manually turned on via the debugfs program.
4011 Clarified e2fsck error message which is printed when it cannot find
4012 sufficient contiguous block when relcating filesystem metadata.
4014 Added support for building an EVMS plugin module for ext2/3. This
4015 module is substantially the same as the EVMS module shipping with EVMS
4016 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4017 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4018 if the configure --enable-old-evms flag is given.
4020 Fsck will search through EVMS volumes when trying to resolve
4021 filesystem specifications such as LABEL=xxx or UUID=xxx.
4023 Added a new utility program, /sbin/findfs, which will return
4024 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4027 Update and clarified various man pages. (addresses Debian Bug #145044,
4028 #146437, #131350, #151990, #144621, #141938)
4030 If there are no filesystems specified on fsck's command line, fsck now
4031 treat that as if the -As options were given. Previously it would
4032 simply do nothing. (Addresses Debian Bug #153102)
4034 Mke2fs no longer treats a failure to be able to clear the MD signature
4035 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4038 The e2p library functions (which are used by lsattr and chattr) now
4039 double check to make sure the file is a regular file or directory
4040 before attempting to use the ext2 ioctls. Some device drivers
4041 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4042 (Addresses Debian Bug #152029).
4044 The extended attribute handling has been updated to correspond with
4045 the latest V2 bestbits ACL code.
4047 Fixed bug in e2fsck which caused it to not clear the dtime field when
4048 processing truncated inodes on the orphan list. This could cause data
4049 loss(!) if a filesystem is rebooted before a truncate has been
4052 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4053 algorithms. This makes e2fsck much faster in the case of severely
4054 corrupted filesystems where a large number of blocks are claimed by a
4055 large number of inodes. (Thanks to the 2.5 IDE device driver for
4056 inspiring this work.)
4058 Resize2fs has been significantly sped up when shrinking and expanding
4059 a filesystem by a very small number of blocks (for example, when EVMS
4060 is converting a partition to be an EVMS legacy volume).
4062 Added a new option to e2fsck, -D, which will optimize or compress all
4063 of the directories in the filesystem.
4065 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4066 properly clean up and only exit at safe points. Fsck will pass
4067 SIGINT/SIGTERM to its child processes, and wait until they have all
4068 exited before it exits.
4070 The uuid parsing code in the uuid library now properly complains when
4071 an illegally formated uuid is presented to it. (Addresses Debian bug
4074 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4075 and 2.4.17, since the workaround can cause problems when using a 2.4
4076 kernel with an old version of glibc built with the 2.2 headers.
4078 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4079 superblock used by other filesystems. (Addresses Debian bug #147256.)
4081 Added support for the synchronous directory feature written by Andrew
4084 The debugfs program can delete directories using the rmdir command.
4086 Add support for 8k and 16k filesystems (for systems with page sizes
4087 that are greater or equal to 8k or 16k, respectively). Note that
4088 these filesystems can not be mounted on x86 systems, or other systems
4089 with only 4k page sizes, due to limitations in the current Linux VM
4092 Resize2fs requires that the filesystem state be valid and have no
4093 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4094 required that the last fsck time be greater than the last mount time.)
4096 Configure now defaults the man pages directory to /usr/share/man on
4099 E2fsck now offers to truncate inodes which contain too many blocks (so
4100 that i_blocks would overflow. Also fixed handling of large sparse
4103 E2fsck now more completely checks for symlink validity, including
4104 requiring NULL termination and length checks.
4106 E2fsck will offer to try forcing a disk write to remap a bad block
4107 after finding a read error when reading a filesystem metadata block.
4109 Fixed a bug in debugfs which caused the -b and -s options to crash
4110 debugfs, as well as breaking the testb, setb, and clearb functions.
4112 Added a bmap command to debugfs which calculates the logical to
4113 physical block mapping for a particular inode.
4115 Fixed a bug in code which checked to see if a device was mounted which
4116 sometimes (rarely) failed in the case of a plain file.
4118 Fixed a bug in resize2fs where when it reported an error, it would
4119 print a message erroneously indicating that the filesystem had been
4120 resized before it aborted.
4122 When resizing a plain file which is smaller than the requested size,
4123 resize2fs will attempt to extended the file so that programs like
4124 e2fsck will not complain that the file is too small.
4126 Resize2fs will print the actual new size of the filesystem when it is
4129 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4130 information on big-endian systems.
4136 Fixed collisions with C++ reserved words.
4138 Added portability fixes for building e2fsprogs on the HURD and AIX.
4140 Added the ext2ed program for creation of test cases. (ext2ed has many
4141 limitations and bugs which make it unsuitable for production use.)
4143 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4144 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4145 name_len field is byte swampped on big-endian machines, since in the
4146 V2 structure, name_len is a char field which is doesn't need to be
4147 byte swapped --- except if an old-style kernel had byte-swapped the
4148 name_len field as part of the V1 structure.
4151 E2fsprogs 1.27 (March 8, 2002)
4152 ==============================
4154 The warning messages for mke2fs now go to standard error.
4156 Fixed to make sure "make check" runs all of the test programs with
4157 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4159 The mke2fs program checks the boot sector for the BSD disk label, and
4160 avoids erasing it if it is there.
4162 Fixed a bug in e2fsck which caused it to core dump if the journal
4163 inode was missing when it was supposed to be there.
4165 E2fsck now prints ranges in pass 5 when printing deltas for the block
4168 Debugfs's "ls -l" command now will print out the file type information
4169 in the directory entry.
4171 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4172 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4174 Debugfs can now examine the experimental directory indexing
4177 Fixed bug in debugfs which caused it to core dump if modify_inode is
4178 called without an open filesystem.
4180 The debugfs lsdel command now runs its output through a pager first.
4182 When installing manual pages, remove the compressed manual pages first.
4184 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4186 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4187 actually broke things on mips32, sparc32, and Alpha platforms.
4189 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4190 (which is required by the newer libintl libraries).
4195 Fixed various gcc -Wall complaints.
4197 Fixed a few memory leaks in the e2fsck journaling code, and in the
4198 ismounted code checking for a swap device.
4200 Add new inode I/O abstraction interface which exports an inode as
4203 Exported ext2_file_flush as a public interface.
4205 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4207 Lots of small random portability fixes to make e2fsprogs build under
4208 AIX --- even without the 5L compatibility toolkit, and even using the
4209 uber-crippled AIX native C compiler.
4212 E2fsprogs 1.26 (February 3, 2002)
4213 =================================
4215 Dumpe2fs will keep going now if the bad block inode can't be read.
4216 (Previously it stopped with a fatal error.)
4218 E2fsck will now give an opportunity to run the journal even if the
4219 recovery flag is not set. This is the default behaviour if e2fsck is
4220 using a backup superblock, since the needs_recovery flag will never be
4221 set in the backup superblock copies.
4223 E2fsck now automatically finds the backup superblock/group descriptors
4224 even when the primary superblock is completely destroyed for 2k and 4k
4225 filesystems. (Previously it just guessed/assumed that we were dealing
4226 with a 1k filesystem in that case, and users had to manually specify
4227 the backup superblock number.)
4229 Fixed a bug in e2fsck where it dereferences a null pointer when there
4230 is a problem opening a filesystem in preen mode.
4232 E2fsck now handles external journals correctly; previously it trashed
4233 the external journal device if the journal needed to be replayed.
4235 Work around ulimit incompatibility problem caused by recent 2.4
4236 kernels; the unix IO module will automatically try to set any resource
4237 limits to be infinite on startup.
4239 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4240 bitmap if it wasn't present and the blocksize was 2k or 4k.
4241 (Addresses Debian Bug #116975)
4243 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4244 clearing the new V2 fields if they do not make sense or if the ext3
4245 superblock is version 1 superblock.
4247 E2fsck will automatically relocate the ext3 journal from a visible
4248 file (i.e., /.journal) to an hidden inode if the filesystem has been
4249 opened read/write. This allows the users to add a journal while the
4250 filesystem is mounted, but the next time the system is rebooted, the
4251 journal file will disappear. This avoids problems with backups,
4252 stupid operators with superuser bits, etc.
4254 Fix a bug in fsck where it would not support a filesystem type of
4255 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4257 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4258 automatically identify reiserfs filesystems.
4260 The number of processes spawned by fsck can now be limited using the
4261 FSCK_MAX_INST environment variable.
4263 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4264 should be searched for UUID and label information.
4266 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4267 limit if at all possible, when opening a block device. (The filesize
4268 limit shouldn't be applied against writes to a block device.)
4270 In mke2fs and e2fsck, specifying the -c option twice will now do
4271 a read/write test on the disk. Update the man pages to encourage
4272 using the -c option, and to discouraging running badblocks separately,
4273 since users tend to forget to set the blocksize when running
4276 Mke2fs now automatically clears the immutable attribute on a
4277 pre-existing .journal file left over from a previous failed attempt to
4278 add a journal to an alreadyy-mounted filesystem.
4280 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4283 Mke2fs now creates the lost+found directory with permissions of 0700,
4284 so that files that had previously lived in protected directory are
4285 safe if they get dropped in lost+found and the system administrator
4286 doesn't deal with immediately. (Addresses Debian #bug 118443)
4288 Mke2fs and e2fsck (and all programs that use the
4289 ext2fs_check_if_mounted function) will now properly identify that a
4290 device is mounted, even in cases where devfs has confused things with
4291 multiple devices names with the same identity, or if a dim-witted
4292 system administrator has done something stupid like creating device
4293 file aliases in their home directory. Also now checks for swap devices
4294 by using /proc/swaps. (Addresses Debian bug #106622)
4296 Added a new option (-T) to tune2fs which sets the time a filesystem
4299 Speed up e2image when creating sparse raw image files by optimizing
4300 away excess lseek() system calls.
4302 Fix support of large (> 2GB) files when used as a filesystem in
4303 mke2fs, tune2fs, debugfs, and findsuper.
4305 Debugfs's stat and icheck commands now properly deals with large (>
4308 Debugfs's set_super_value command now prints out the list of valid
4309 superblock fields which can be set using the command.
4311 Debugfs's rm and kill_file command now updates the superblock free block
4312 and inode counts, thus keeping the filesystem consistent.
4314 Debugfs's lsdel command now takes an optional argument which allows
4315 the user to only see the most recently deleted files.
4317 A new command (undel) was added to debugfs which automates
4318 undeleting a deleted inode and linking it back to a directory.
4320 Debugfs's ls command now takes a new option, -d, which lists
4321 deleted directory entries.
4323 Debugfs's testb, freeb, setb, and find_free_block commands now take an
4324 optional count argument.
4326 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4327 be used to signal that a particular inode should not be eligible for
4328 tail-merging --- this is needed for programs like LILO.
4330 The findsuper (an unreleased, uninstalled utility program) has been
4331 improved to add extra validity checks and to add a progress meter.
4332 (It is still an unsupported program; the officially supported way to
4333 recover from a trashed partition table is to use gpart; findsuper is
4334 for wizards only. :-)
4336 Debugfs was fixed to compile with "configure --disable-swapfs".
4338 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
4340 Added new translation file for Turkish.
4345 Fix general gcc -Wall complaints.
4347 E2fsprogs (mostly) works with the dietlibc.
4349 The programming texinfo file has been expanded to include description
4350 of additional libext2fs functions. (Still not compeltely done, but a
4351 lot of the more important functions have been documented.)
4353 Added a umask structure to struct_ext2_filsys, which currently only
4354 modifies the behaviour of ext2fs_mkdir(), but if we add any file
4355 creation functions to libext2fs, we should also make sure they respect
4358 The build-rpm script was fixed to be a bit more safe.
4360 The tests' Makefile now has a way of automating test case creation
4361 for e2fsck, using "make testnew".
4363 Created a new function, ext2fs_dir_iterate2 which passes more
4364 information to the callback function (identical to the one used by
4365 ext2fs_dblist_dir_iterate). The directory iterator functions take a
4366 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4367 directory entries. If the directory entry is deleted, the callback
4368 function will be called with the entry paraemter set to
4369 DIRENT_DELETED_FILE.
4371 Added new functions, ext2fs_inode_alloc_stats and
4372 ext2fs_block_alloc_stats, which takes updates block/inode allocation
4373 statistics in the bitmaps, block group descriptors, and superblock
4374 when inodes or blocks are allocated or deallocated.
4377 E2fsprogs 1.25 (September 20, 2001)
4378 ===================================
4380 This is primarily a bug-fix release; no new features were added, but
4381 there are a number of embarassing bug fixes and cleanups applied.
4383 Fix a bug mke2fs which causes stack garbage to be written to disk when
4384 zapping disk sectors. (This bug could cause mke2fs to core dump for
4385 some kernels, I suspect with security enhancement patches.)
4387 Remove unneeded #include of <linux/config.h> which was breaking
4388 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
4390 Updated tune2fs man page to reflect the fact that adding or removing a
4391 journal doesn't require running e2fsck.
4393 Remove use of AC_REQUIRE from autoconf which had been used to prevent
4394 AC_CANONICAL_HOST from being called twice; unfortunately this causes
4395 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4396 used outside of autoconf macros. Fortunately, it doesn't seem to be
4397 necessary any more, anyway.
4399 E2fsck will now not fall back to an alternate superblock if the user
4400 specifies the superblock location explicitly on the command-line.
4401 This allows easier recovery from a situation where the primary
4402 superblock and block groups are slightly corrupted, but the backup
4403 superblocks are completely broken.
4405 Fix problem which caused compile_et and mk_cmds to blow up if
4406 e2fsprogs was in a directory with a pathname that contained spaces.
4408 We are now more paranoid about checking the entry in /etc/mtab to make
4409 sure the filesystem is really mounted, since some broken distributions
4410 (read: Slackware) don't initialize /etc/mtab before checking non-root
4411 filesystems. (Slackware also doesn't check the root filesystem
4412 separately, and reboot if the root filesystem had changes applied to
4413 it, which is dangerous and broken, but there's nothing I can do about
4416 Make UUID library C++ friendly by adding appropriate extern "C"
4417 declarations and using const in the function declarations.
4419 Fix up the com_err texinfo file so that it can product a valid info
4420 file (previously, it could only be used to generate paper
4421 documentation using texinfo.tex).
4424 E2fsprogs 1.24a (September 2, 2001)
4425 ===================================
4427 Fix brown-paper bug in mke2fs which caused it to segfault when
4428 printing the version string.
4431 E2fsprogs 1.24 (August 30, 2001)
4432 ================================
4434 Revert the BLKGETSIZE64 support, since for some distributions, this
4435 ioctl has been used by an unofficial kernel patch to update the last
4436 sector on the disk, and this was causing disk corruption problems as a
4439 Mke2fs is now more careful about zapping swap space signatures and
4440 other filesystem/raid superblock magic values so that programs like
4441 mount who try to use hueristics to determine the filesystem type of a
4442 partition are less likely to be confused.
4444 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4445 regular file (since Andreas Dilger's on-line resizing tools will set
4448 Fixed some minor texinfo, man pages nits for spelling errors,
4449 texinfo warnings, etc. (Addresses Debian bug #110621.)
4451 E2fsprogs program no longer print the filesystem version number
4452 (i.e. 0.5b), since it only confuses people and doesn't serve any real
4455 E2fsck will once again compile under libc5, since it will supply its
4456 own version of strnlen if necesssary.
4458 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4459 when specifying the external journal device. tune2fs will also search
4460 devices looking for the externla journal debice when removing.
4462 E2fsprogs 1.23 (August 15, 2001)
4463 ================================
4465 Add initial support for extended attributes (EA); e2fsck will
4466 correctly handle a filesystem with EA's and check the EA blocks for
4469 E2fsck's symlink sanity checking has been cleaned up. It now checks
4470 the i_size value of fast symlinks, and checks for immutable flags
4471 being set of symlinks, etc.
4473 E2fsck now offers to clear inodes which are special files that have a
4474 non-zero i_blocks or i_size field. (The i_size field check was in the
4475 previous version of the code, but due to a bug it didn't offer to
4476 clear the inode unless i_size and i_size_high were both non-zero.)
4478 E2image can now create "raw" image files, which only contain the
4479 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4480 debugfs, etc., can be run directly on the raw image file.
4482 Add support for the 64-bit block device patches.
4484 Fixed bugs in creating external journals with a 1k blocksize.
4486 Add initial support for external journals (so long as the external
4487 journal only supports a single filesystem) in e2fsck.
4489 Remove requirement for needing to run fsck on a filesystem after
4490 removing a journal (either internal or external).
4492 The man pages now document how to create and manage external journals.
4494 Speed up the check of an ext3 filesystems by avoiding a needless flush
4495 of all of the superblock and block group descriptors.
4497 Speed up creating an internal journal using tune2fs in the case where
4498 the filesystem has a lot blocks already allocated.
4500 Tune2fs has been fixed to make sure that only error messages go to
4501 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4503 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4504 now not set the sparse_super feature. (Addresses Debian bug #108165)
4506 Add support in fsck for the filesystem type "auto".
4508 Fsck -A will not try to interpret device names for filesystems which
4509 have a pass number is 0. (Addresses Debian bug #106696).
4511 Fsck prints a warning message if now valid filesystems are passed to
4512 it. (Addresses Debian Bug #107458.)
4514 E2fsck now gives an explicit warning if there filesystem still has
4515 errors at the end of the run. (Addresses Debian bug #104502)
4517 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4518 reflects an error. E2fsck will also not run the orphan list if the
4519 filesystem contains errors, since the orphan list might be corrupted.
4521 E2fsck now prints the number of large files when given the -v option.
4523 Fixed minor memory leaks in e2fsck.
4525 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4528 E2fsprogs 1.22 (June 22, 2001)
4529 ==============================
4531 Fixed a bug in e2fsck's handling of orphan inodes which are special
4532 files (i.e., block/character device files, named FIFO's, etc.).
4534 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4535 tune2fs to fail at adding a journal to a mounted filesystem.
4537 Fixed a few big-endian bugs in e2fsprogs
4538 * The directory block functions were accidentally reporting
4539 some directories as corrupted when they weren't.
4540 * If e2fsprogs is compiled --disable-swapfs, the C language
4541 equivalents weren't being included for big-endian platforms.
4542 (Fixes Debian bug #101686).
4544 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4549 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4550 ioctls, and allow them to be defined for non-i386 platforms.
4552 The uuid.h header file is now protected against multiple inclusions.
4554 E2fsprogs is now being developed using BitKeeper. Changed the test
4555 scripts to deal with BK's stripping CR characgters from text files,
4556 and changed the top-level Makefile.in to avoid including BitKeeper
4557 files when generating the source tarball.
4560 E2fsprogs 1.21 (June 15, 2001)
4561 ==============================
4563 Added new configure flags which allow a subset e2fsprogs to be built;
4564 this is most useful for boot floopies, since the resulting shared
4565 libraries and programs are slimmed down by removing features that
4566 aren't necessary for a boot floppy. The new flags that were added
4567 are: --disable-swapfs, which removes support for byte swapping old
4568 legacy PPC/68k filesystems, --disable-debugfs, which removes support
4569 for debugfs from the libext2fs library, --disable-imager, which
4570 removes support for the e2image program, and --disable-resizer, which
4571 removes support for resize2fs.
4573 E2fsck now prints the number of mounts or days elapsed since the last
4574 check when e2fsck is forced to check an otherwise clean filesystem.
4576 Tune2fs now prints an informative message about how often a filesystem
4577 will be checked when adding a journal to the filesystem, to remind the
4578 user that he/she may want to adjust those parameters using tune2fs
4581 Worked around hurd brain-damage which causes e2fsck to sometimes
4582 believe a filesystem is the root filesystem based on device numbers
4583 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4586 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4587 erroneous error with the -F option was specified.
4589 Fixed a ext3 recovery bug in the revoke handling; synchronized with
4592 Fixed two bugs in e2fsck's handling of dup block handling, dealing
4593 with relatively uncommon edge cases: a directory with an indirect
4594 block which is claimed by another file, and when the last inode in the
4595 filesystem has blocks claimed by another file.
4597 E2fsck now checks to see if the i_size field of a fast symlink is too
4598 big, and offers to clear the symlink if so.
4600 E2fsck now checks to see if i_size_high of special files is non-zero,
4601 and offers to clear i_size_high.
4603 Fix e2fsck's handling of incompatible journal flags so that the user
4604 has chance to abort, and then has the option to clear out the journal
4605 entirely. (Addresses Debian bug #98527.)
4607 Fixed a bug in fsck which could cause it to core dump if a mix of
4608 standard and non-standard device names are used in /etc/fstab.
4609 (Debian bug #100559)
4611 Fixed a bug in debugfs which caused read errors when copying a file to
4614 The debugfs set_super_value command can now modify the s_lastcheck field.
4616 Fixed a bug in lsattr and chattr which was accidentally introduced in
4617 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
4618 directories correctly because the change modified the layout of struct
4619 dirent to be incompatible with the libe2p shared library.
4621 Cleaned up the mke2fs manual page and included a discussion about why
4622 it's good to periodically check the filesystem even when journaling is
4628 Fix general gcc -Wall complaints.
4630 The types needed by the ext2 header files are now provided by
4631 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4633 Integers are now preferred to longs when trying to find a 32-bit type
4634 in ext2_types.h. Also, if linux/types.h has already been defined,
4635 don't try to redefine the types.
4637 Fixed make depend script so that it automatically corrects the
4638 pathname cleanups performed by make -M, so I don't have to fix them up
4641 Fixed the d_loaddump test case to be more robust, and not depend on
4644 Removed debugfs's dependence on pread(), which was accidentally
4645 intrudced in e2fsprogs 1.20
4647 Fixed a performance bug in the libext2fs's icount routine; the size
4648 estimate of the icount array was incorrectly being calculated.
4650 Removed use of the badblocks compatibility functions in the e2fsprogs
4653 Added paranoia code which protects against strange cases where /etc
4654 isn't on the root filesystem, or if /etc/mtab doesn't exist.
4656 The header file ext2_types.h is now installed.
4658 Autoconf is used to determine when we are on big-endian machines,
4659 instead of doing run-time tests, to save a few bytes of code.
4661 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4662 functions are no longer inline functions, which saves space and
4663 doesn't really cost any real performance.
4665 The ext2fs library no longer depends on the e2p library. (What need
4666 there was of it --- namely, fsetflags, was coded in-line).
4668 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4669 when the user is stupid and tries compiling the package using "make
4672 Miscellaneous code cleanups:
4673 * Added missing files from Makefile.in's SRCS file, so that
4674 their dependencies would be properly calculated.
4675 * Removed redundant code
4676 * Fixed comments in code
4677 * Removed no-longer unneeded argsused #pragma.
4680 E2fsprogs 1.20 (May 20, 2001)
4681 =============================
4683 Add support for replaying the ext3 journal purely in user mode,
4684 including handling the orphaned inode list. Used code contributed by
4685 Andreas Dilger, with bug fixes and the orphaned inode handling done
4688 The mke2fs and tune2fs programs can create or modify a filesystem to
4689 include an ext3 journal. Tune2fs also can be used to remove an ext3
4690 journal from a filesystem.
4692 E2fsck will now check for the existence of a linked list of orphan
4693 inodes in the superblock, and clear those inodes before starting the
4694 rest of the filesystem check (but after the journal playback).
4696 E2fsck now validates the file descriptor passed to the -C option,
4697 which saves against the completion bar getting written to an
4698 unexpected location, such as the disk being checked. (Debian
4699 bug/wishlist #55220)
4701 E2fsck will now bump the filesystem revision number from zero to one
4702 if any of the compatibility bits are set.
4704 Fixed a bug where a badly corrupted directory on a big endian system
4705 could cause e2fsck to die with a bus error. The
4706 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4707 the ext2 library now does alignment sanity checks on the rec_len field
4708 of the directory entry before using it.
4710 The ext2 library has been enhanced to make tune2fs safe to run on
4711 mounted filesystems. (Users could usually get away with using tune2fs
4712 on mounted filesystems before, but with the advent of ext3 and
4713 journaling, it became important to make tune2fs was *really* safe for
4714 use even when the filesystem being modified is mounted.) E2label is
4715 now implemented by tune2fs using an argv[0] dispatch, so that e2label
4716 is also now safe for use on mounted filesystems.
4718 Added a new program, e2image, which creates a backup of critical ext2
4719 filesystem data structures. The generated image file can be examined
4720 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4721 the image file to help recover very badly damaged filesystems.
4723 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4724 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4725 large file when deciding whether or not the filesystem has large files.
4727 Fixed lsattr and chattr so that they work correctly on large files.
4728 (Fixes Debian bug #72690.)
4730 Removed limitation in get_device_size() which imposed a one terrabyte
4731 filesystem limitation. (Most 2.2 kernels still have a signed int
4732 problem which cause 1 TB block device limitation. Fortunately, the
4733 kernel patches to fix this are much easier than fixing the 2TB
4734 limitation in the kernel. :-)
4736 A max_mount_count of zero is now treated as if no mount count were
4737 set. (Previously, no mount count was indicated by using -1, and a
4738 mount count of zero caused e2fsck to always be run.)
4740 Mke2fs supports two new filesystem types largefile and largefile4.
4742 Mke2fs now adds some randomness in s_max_mount_count so that multiple
4743 filesystems won't be all checked at the same time under normal
4746 Fixed bug in the progress bar printing code which could cause e2fsck
4747 to core dump on an illegal filesystem.
4749 Fixed bug in fsck which could allow more than one instance of e2fsck
4750 to be printing a progress bar. (Debian bug #65267)
4752 Fsck using a UUID or a LABEL specifier will work even if devfs is
4753 compiled into the kernel and not mounted. If the pathnames in
4754 /proc/partitions are incorrect, fsck will search /dev for the correct
4755 device (using the new ext2fs_find_block_device library function).
4756 Fsck now also checks the RAID devices first so that they are properly
4757 found when they are in use. Support has also been added to support
4758 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4760 Fixed a bug in fsck which caused it not deal properly with 16
4761 byte long filesystem labels.
4763 Fsck's -t option has been made a lot more flexible. The semantics for
4764 what happens if a comma-separated list to fsck has been regularized,
4765 and it is now possible to filter what filesystems will get checked
4766 based what is in the filesystem's fstab entry's option field. (Debian
4769 The dumpe2fs program can now print out the group description
4770 information in hex, and also prints the location of the superblock and
4771 block group descriptor for those block groups that have them.
4773 Mke2fs now clears the ext2 superblock before it starts creating a
4774 filesystem, so that the superblock magic number is only written if the
4775 filesystem creation process successfully completes.
4777 The debugfs program's stat command now pretty-prints the blocks used
4778 by an inode so that it's more compact and informative.
4780 The debugfs stats command now uses the same libe2p code (which is used
4781 by dumpe2fs) to print the superblock header information. This is more
4782 complete, and it avoids a bit of code duplication.
4784 Added a new debugfs command, set_super_value (ssv) which allows the
4785 user to set arbitrary superblock fields.
4787 Debugfs was extended to support inode numbers in hex (by prefixing
4788 them with 0x), and so that modify_inode can set the inode generation
4789 number. Also, there is now a new function command called logdump
4790 which will dump an ext3 journal.
4792 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4795 Debugfs's dump command now stops immediately upon reporting a disk
4796 read error. (Fixed a bug in ext2fs_file_read library routine which
4797 caused debugfs not to stop.) (Debian bug #79163)
4799 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4800 checked before /etc/mtab is used, since /proc/mounts is more likely to
4803 Added portability fixes for Solaris and Linux/ia64.
4805 Various manual pages were clarified and cleaned up. (Fixed debian
4806 bugs #63442, #67446, and #87216)
4812 The e2fsck message printer now supports %Iu and %Ig, which will print
4813 out the inode's user and group owners, respectively.
4815 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4816 that no longer dependent on the system having the correct version of
4817 the kernel header files.
4819 Added a new function to libext2, ext2fs_find_block_device(), which
4820 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4821 device given its device number.
4823 Added a new function to libext2, ext2fs_sync_device, which centralizes
4824 all of the places which might try to use the BLKFLSBUF or FDFLUSH
4825 ioctls (and usually failing to define them since the system header
4826 files don't usually do this for us, and we're trying to avoid usage of
4827 kernel include files now).
4829 Added new utility programs in tests/progs: random_exercise and
4830 hold_inode. They aren't built by default; they're useful for
4831 exercising ext3 filesystem code.
4833 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4834 the filesystem close functions to only update the superblock, and to
4835 not touch the block group descriptors. Needed by tune2fs when
4836 modifying a mounted filesystem.
4838 Got rid of struct ext2fs_sb and replaced it with the standard struct
4839 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
4840 source (but not binary) compatibility of some users of the ext2
4841 library. Those applications should just simply do a global search and
4842 replace of struct ext2fs_sb with struct ext2_super_block, and include
4843 the new header file <ext2fs/ext2_fs.h> which defines it.
4845 The ino_t type has been renamed ext2_ino_t to protect applications
4846 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4847 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
4848 unexpected ABI change.
4850 The Makefiles have been reworked so that "make check" can be run from
4851 the top-level Makefile.
4853 Fix general gcc -Wall complaints and removed dead code.
4855 Remove use of NOARGS, because we assume everyone does ANSI C these
4858 Added build-rpm script from sct.
4860 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
4863 New function ext2fs_flush_icache which must be called if the
4864 application program modifies the inode table blocks without going
4865 through ext2fs_write_inode() interface.
4867 New ext2fs_check_mount_point() function, which will return the mount
4868 point of a device if mounted.
4870 The io_channel abstraction now has an optional interface,
4871 io_channel_write_range, which allows specific byte ranges to be
4874 The unix_io IO channel now supports write-through caching, so that
4875 journal creation is more efficient.
4877 Added x86 assembly language routines to support byte swapping, to
4878 reduce executable size.
4880 Fixed bug in the utility program subst so that it's possible to
4881 replace a substitution variable with a zero-length string.
4883 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4884 slipped into some of the problem number.
4886 E2fsprogs 1.19 (July 13, 2000)
4887 ==============================
4889 Release the resize2fs program since the timeout before it could
4890 be released under the GPL has finally expired.
4892 Add experimental support needed for the ext2 compression patches.
4893 This requires compiling e2fsprogs with the --enable-compression flag
4894 to the configure script.
4896 Added ext3 journalling support. E2fsck will run the journal (if
4897 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
4898 installed as a symlink to e2fsck. Fsck has been taught about ext3,
4899 and treats it the same as ext2 in terms of the progress bar logic.
4900 Dumpe2fs will display the superblock journaling information if the
4901 filesystem has a journal. The ext2 library will now permit opening an
4902 ext3 filesystem with the recovery flag set. This is necessary for
4903 on-line dump's to work correctly, but there may be issues with this
4904 working well since ext3 is much less agressive about syncing blocks to
4905 the filesystem, since they're safe on the journal.
4907 Tune2fs and e2fsck have been changed to allow the mount_count check to
4908 be disabled by setting max_mount_count to -1. (This was already
4909 supported by the kernel.)
4911 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4912 are used for ext3 as well.
4914 Added internationalization support for e2fsprogs; must be enabled
4915 by passing --enable-nls to configure.
4917 Always use the provided ext2fs header files to insulate ourselves from
4918 kernel version changes. Which include files are used by e2fsprogs
4919 have also been cleaned up to improve portability.
4921 Limit the number of times that e2fsck updates the progress bar so that
4922 people who are booting using a 9600 baud console don't get swampped by
4925 Improved the loop detection algorithm in e2sck's pass #3 so that it is
4926 much, much faster for large filesystems with a large number of
4929 The memory footprint for e2fsck is now slightly smaller than before.
4931 E2fsck now checks if special devices have a non-zero size, and offers
4932 to clear the size field if it finds such an inode.
4934 E2fsck now checks if special devices have the append-only flag set,
4935 and offers to clear the inode.
4937 E2fsck now properly handles some "should never fail" cases during a
4938 bitmap copy in pass5.
4940 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4942 E2fsck now calculates the correct location of the backup superblock in
4943 the case of filesystem blocksizes > 1k.
4945 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4946 which normally didn't cause problems under most filesystem parameters,
4947 but could cause a valid superblock to be rejected in extreme cases.
4948 Other checks for validating superblock values were made more
4951 Added non-destructive write testing to the badblocks program, courtesy
4952 of David Beattie. The badblocks also now has an option to input the
4953 current set of bad blocks, so that known bad blocks are skipped to
4954 speed up the badblocks test. There is also a persistent rescan
4955 feature which causes badblocks to run until it has completed some
4956 number of passes without discovering any new bad blocks.
4958 Badblocks now checks to see if the device is mounted and refuses to do
4959 the tests involving writing to the device if it is mounted. Also,
4960 badblocks now allows the number of blocks to be checked to be
4961 defaulted to the size of the partition.
4963 Fixed a bug in fsck which didn't allow non-root users to be able to
4964 check filesystems if there were any LABEL= or UUID= entries in
4967 The Hurd doesn't support the filetype filesystem feature. The mke2fs
4968 program now makes sure that for the Hurd, the filestype feature is
4969 turned off. E2fsck will check to see if the filetype feature is
4970 turned on for Hurd filesystems, and offer to turn off the feature.
4972 Mke2fs now has a safety check to make sure the number of blocks do not
4973 exceed 32 bits even on a 64 bit platform.
4975 Really fixed a bug in fsck to allow "fsck -As" to run interactive
4976 fsck's. (For those people who like to do interactive fsck's in the
4979 Debugfs has a few new features: the rdump command, which will do a
4980 recursive dump of a directory and all of its contents, and the lcd
4981 command which does a local chdir (much like the ftp command of the
4982 same name). In addition, the debugfs program and the open_filesystem
4983 command now takes three new options: -b and -s, which allows the
4984 blocksize and superblock location to be specified, and the -c option
4985 which is used in catastrophic situations where the block group
4986 descriptors are corrupt. If the -c option is specified, debugfs will
4987 skip trying to read in the block and inode bitmaps.
4989 Debufs's lsdel command was fixed to handle bad blocks in the inode
4992 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
4995 General improvements in error messages
4997 - Mke2fs prints a sane error message if the partition size is zero
4998 (usually because the partition table wasn't reread by the
4999 kernel due to the partition being busy), instead of "invalid
5000 argument passed to ext2 library while initializing superblock".
5002 - Fsck now prints more self-explanatory message if an invalid UUID=
5003 or LABEL= specification is passed to it.
5005 UUID library changed to use the LGPL.
5007 Fixed a bug in the UUID library where very rapid calls to the
5008 time-based UUID generator could cause duplicate UUID's to be returned.
5009 This was not a problem for e2fsprogs, but it could be a problem for
5010 other users of the library.
5012 Make the UUID library more robust in the face of missing or an
5013 improper /dev/urandom or /dev/random files.
5015 Added some random portability fixes for Solaris.
5017 Some minor man page updates.
5019 Fixed a memory leak in the ss library.
5025 We now try to use lseek64 and open64 from the LFS if possible.
5027 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5030 The mark and unmark bitmap functions now return the previous state of
5031 the bit that was being changed, which is useful for some speed
5034 The following functions have been added to enhance the badblocks list
5035 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5036 ext2fs_badblocks_equal.
5038 The ext2 header files now have the latest journalling fields to the
5041 The ext2fs_mkdir function in libext2fs now properly backs out of error
5042 conditions robustly.
5044 Cleaned up makefiles:
5045 - to cleanly compile with the -j flag.
5046 - so distclean removes all generated files.
5047 - so in case of an error while installing header files, the make aborts.
5049 Fix test_script so that it works correctly when compiling in the
5052 The random UUID generation routine has been made slightly better in
5053 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5054 is still not recommended if /dev/random doesn't exist, however; it's
5055 better to use the time/ethernet MAC address UUID in this case.)
5057 Clean up the build process so it's more friendly in case of missing
5060 The ext2fs header file can now be #include'd into C++ programs.
5062 The e2p.h header file is now installed.
5064 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5068 E2fsprogs 1.18 (November 10, 1999)
5069 ==================================
5071 Fix a core dumping bug in e2fsck if an imagic inode is present or
5072 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5073 has to restart pass 1 processing. E2fsck now closes the filesystem
5074 before freeing a large number of its data structures, so in the case
5075 of future memory faults, at least the fixed filesystem will be fully
5078 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5079 imagic inode, it will offer to clear the imagic flag.
5081 E2fsck will now offer to clear the immutable flag on special files
5082 (device/socket/fifos) when running it in non-preen mode.
5084 E2fsck will now set the filetype when creating /lost+found, and when
5085 connected orphaned inodes to /lost+found.
5087 Debugfs's ncheck and icheck commands now handles the case where there
5088 are bad blocks in the inode table without bombing out.
5090 The badblocks list processing code has been made more efficiently for
5091 appending a large number of (ordered) badblocks to the badblocks list.
5093 Some minor man page updates.
5095 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5096 mode, but some people like to do this in boot scripts for silly reasons).
5101 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5102 with the problem code convention.
5104 The badblocks list regression test program has been updated to work
5105 with previously made API name changes.
5107 The ext2fs_free() command now uses the new badblocks API to avoid
5108 using the compatibility layer.
5110 Added new regression test cases; the run_e2fsck test script now
5111 supports the ability for a test case to run a prepratory command
5112 before running e2fsck.
5114 E2fsprogs 1.17 (October 26, 1999)
5115 =================================
5117 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5120 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5121 thus potentially causing problems if a binary UUID contained a NULL
5124 E2fsck now uses stricter checks for directory entries in pass 2:
5125 zero-length filenames are not allowed; neither are 8 byte long
5128 The debugfs "dirty" command now clears the filesystem valid bit.
5129 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5130 bit in the in-core superblock image. The new functionality is more
5131 what the user expects, and is more useful.)
5133 Added a debugging hook to test parallel fsck; if the environment
5134 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5135 will be checked in parallel when they normally would not be.
5140 Fixed some #ifdef's for compilation under the Hurd OS.
5142 Fixed minor W2K compatibility problems.
5144 Fixed some miscellaneous GCC warnings.
5147 E2fsprogs 1.16 (October 22, 1999)
5148 =================================
5150 Fixed a race condition bug in fsck; when printing a progress bar, if
5151 checking multiple filesystems in parallel, it was possible for fsck to
5152 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5153 handler, which would cause it to terminate with a signal 10.
5155 E2fsck now properly handles filesystems that have the
5156 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5157 filesystem into using or not using FILETYPE feature.
5159 E2fsck now properly handles filesystems that have the IMAGIC feature
5160 turned on (this is used on Linux AFS servers).
5162 The mke2fs program now creates filesystems that have the filetype and
5163 sparse_superblock features enabled by default, unless it is run on a
5164 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5165 so there is now a new flag -O which allows the user to specify with
5166 which features she would like to create the filesystem; "mke2fs -O
5167 none" will create a filesystsem compatible with 2.0 kernels.
5169 The tune2fs program now has a -O option which allows the user to set
5170 and reset "safe" filesystem features. Currently, the only ones which
5171 allows to be modified are the filetype and sparse_superblock features.
5172 Note setting or clearing either feature will require running e2fsck on
5173 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5174 requires that there is enough free space on the filesystem for the
5175 extra superblocks which will be created by e2fsck.)
5177 Debugfs can now set and print filesystem features in the superblock
5178 using the "features" command. Dumpe2fs will print out the complete
5179 set of features when listing the superblock.
5181 Dumpe2fs has new options -f (force) and -h (header-only).
5183 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5184 message to come up. This could happen when decrementing or
5185 incrementing a link count could result in an overflow.
5187 Fixed a bug in e2fsck where the block count on the lost+found
5188 directory would not be properly incremented when the directory was
5189 expanded to the point where an indirect block needed to be allocated.
5191 E2fsck now makes some additional sanity checks on the superblock to
5192 avoid crashing or giving a memory allocation error if some of the
5193 values in the superblock are unresonable (but the superblock otherwise
5196 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5197 require two passes to completely fix the filesystem. This happened if
5198 an inode claimed blocks that was part of the filesystem metadata
5199 (typically, when garbage was written into an inode table or indirect
5200 block, since this kind of filesystem corruption normally doesn't
5203 On the Alpha, glibc declares st_flags although it isn't actually used;
5204 the configure script was improved to detect this case so that
5205 e2fsprogs can avoid using the non-functional stat field.
5207 The manual pages were updated to use a more consistent formatting
5208 style consistent with standard Unix man pages. Mke2fs's man page
5209 added documentation for a few previously undocumented options.
5211 Fixed minor display bugs in tune2fs and mke2fs.
5216 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5218 Added features to parse and print feature strings into the e2p library.
5219 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5221 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5222 whose directory entries contain proper filetype information if the
5223 filesystem supports it.
5225 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5226 the directory entry filetype information. This is used to set the
5227 directory entry filetype information if the filesystem supports it.
5229 Fixed a bug in ext2fs_expand_dir() where the block count in a
5230 directory's inode would not be properly incremented when the directory
5231 was expanded to the point where an indirect block needed to be
5235 E2fsprogs 1.15 (July 18, 1999)
5236 ==============================
5238 Add configuration checks so that e2fsprogs will compile cleanly on
5239 Linux 2.3 kernels that have renamed i_version to i_generation.
5241 E2fsck now prints a progress/completion bar (and not just a simple
5242 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5243 signal. Fsck will automatically manage the (potentially muliple)
5244 e2fsck processes to print completion bars if it is given a -C option,
5245 with the right thing happening if multiple filesystems are being
5246 checked in parallel.
5248 Mke2fs now has better automatic hueristics to determine the filesystem
5249 parameters to be used for a particular filesystem. Added a new option
5250 -T which allows the user to specify how the filesystem is to be used,
5251 which helps mke2fs do a better job selecting the filesystem parameters.
5253 Mke2fs now creates revision 1 filesystems by default, and with the
5254 sparse superblock feature enabled. The sparse superblock feature is
5255 not understood by Linux 2.0 kernels, so they will only allow read-only
5256 mounts of filesystems with this sparse superblocks.
5258 Fix bug where if /dev/null couldn't be opened (should never happen),
5259 e2fsck would hang in a tight loop.
5261 Make e2fsck handle the case where /lost+found isn't a directory.
5263 E2fsck now uses mallinfo if it exists to get accurate statistics about
5266 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5267 inode had any problems before connecting it to /lost+found.
5269 Add check to e2fsck so it makes sure that total number of inodes in
5270 the filesystem is a sane number.
5272 Fix fencepost error when clearing an the end of the block bitmap which
5273 caused the last block in the bitmap not to get cleared.
5275 Cleaned up a number of messages in e2fsck:
5276 * The message "Group's #'s copy of the group descriptor..."
5277 was fixed so that the correct number would be displayed.
5278 * Added missing space in the "disk write-protected" error messsage
5279 * Cleaned up the error message printed when a non-interactive
5280 e2fsck needs to abort a check because the filesystem
5281 appears to be mounted.
5283 Added a new command-line utility, uuidgen, which will create and print
5286 Make debugfs's icheck command more robust by checking to make sure an
5287 inode has valid blocks before interarting over the inode's blocks.
5289 UUID generation now uses a random-based scheme whenever possible to
5290 prevent potential privacy problems.
5292 Man pages for all of the UUID functions in the lirbary were added.
5294 Fixed bug in fsck so it won't coredump if a filesystem not in
5295 /etc/fstab is given to it.
5297 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5298 that most of the other mount utilities understands.
5300 Mke2fs will make a filesystem even if it appears mounted if the force
5303 Dumpe2fs has new command-line options which allow a filesystem expert
5304 to specify the superblock and blocksize when opening a filesystem.
5305 This is mainly useful when examining the remains of a toasted
5308 The badblocks program has been updated to display correctly on disks
5309 with large block numbers.
5311 The badblocks program no longer gives spurious errors when errors
5312 occur on non-block boundaries, which is common if the blocksize is
5315 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5316 MKE2FS_SYNC environment variable is set. This is to work around a VM
5317 bug in the 2.0 kernel. I've heard a report that a RAID user was able
5318 to trigger it even using a 2.2 kernel, but hopefully it will not be
5319 needed for most Linux 2.2 users.
5321 Fixed miscellaneous documentation and man pages.
5326 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5327 in e2fsck's pass1.c really should have been static.
5329 The return value of the uuid_compare() function was changed to make it
5330 match with the convetions used by strcmp, memcmp, and Paul Leach's
5331 UUID sample document.
5333 The "make depend" process has now been made more automated; it now
5334 automatically word-wraps the dependencies, and only replaces source
5335 Makefile.in if there has been a change in the dependencies. Also, a
5336 top-level "make depend" now recurses through all the subdirectories
5339 The Makefile in .../util has been changed so that subst is built using
5340 the native C compiler during a cross-compilation, since the subst
5341 program is only used during the build process. Also add an explicit
5342 rule to build util/subst by cd'ing to the correct directory and
5345 The man directories are defined in terms mandir, so that the configure
5346 script can override the location of the manual pages.
5348 The config files have been updated to recognize new machine types for
5349 both the i386 and alpha families.
5351 Fsck has been modified so that it will accurately create an
5352 fsck_instance even when the noexecute flag is set. This allows for
5353 accurate debugging of the fsck pass structure. Also, when the verbose
5354 flag is given twice, fsck will print debugging information about when
5355 fsck is waiting for jobs to finish.
5358 E2fsprogs 1.14 (January 9, 1999)
5359 ================================
5361 Fix the fstab parsing code so that it can handle blank lines and
5362 comment characters. Also, missing pass numbers need to be treated as
5365 Fixed a bug in e2fsck where under some circumstances (when e2fsck
5366 needs to restart processing after fixing an egregious inconsistency)
5367 it would try to access already freed memory.
5369 E2fsck now prints non-printable characters in directory entries and
5370 pathnames using '^' and 'M-' notation.
5372 Fixed chattr so that it will ignore symbolic links when doing
5373 recursive descent traversals. For both chattr and lsattr, no longer
5374 print the version string unless the -V option is given.
5376 Allow the system administrator to directly specify the number of
5377 inodes desired in the filesystem, for some special cases where this is
5380 Fix portability problems so that e2fsprogs can be compiled under Linux
5381 1.2 systems and Solaris systems.
5383 Update the config.guess file with a more recent version that will
5384 identify newer Linux platforms.
5389 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5390 an inode number of zero is passed to them.
5392 E2fsprogs 1.13 (December 15, 1998)
5393 ==================================
5395 Fixed a bug in debugfs where an error messages weren't getting printed
5396 when the ext2 library routines to read inodes returned errors in the
5397 stat, cmri and rm commands.
5399 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5400 provided, it won't create an inode table smaller than the minimum
5401 number of inodes required for a proper ext2 filesystem.
5403 Fsck now parses the /etc/fstab file directly (instead of using
5404 getmntent()), so that it can distinguish between a missing pass number
5405 field and pass number field of zero. This caused problems for
5406 diskless workstations where all of the filesystems in /etc/fstab have
5407 an explicit pass number of zero, and fsck could not distinguish this
5408 from a /etc/fstab file with missing pass numbers.
5410 E2fsck will create a /lost+found directory if there isn't one in the
5411 filesystem, since it's safer to create the lost+found directory before
5414 Fixed e2fsck so that it would detect bogus immutable inodes which
5415 happen to be sockets and FIFO files, and offer to clear them.
5417 If a filesystem has multiple reasons why it needs to be checked, and
5418 one of the reasons is that it is uncleanly mounted, e2fsck will print
5419 that as the reason why the filesystem is being checked.
5421 Cleaned up the output routines of mke2fs so that it doesn't overflow
5422 an 80 column display when formating really big filesystems.
5424 Added a sanity check to e2fsck to make sure that file descriptors 0,
5425 1, 2 are open before opening the hard disk. This avoids a problem
5426 where a broken program might exec e2fsck with those file descriptors
5427 closed, which would cause disastrous results if the kernel returns a
5428 file descriptor for the block device which is also used by FILE *
5431 Fixed up the e2fsck progress reporting functions so that the values
5432 reliably reach 100% at the completion of all of the e2fsck passes.
5434 Fixed minor documentation bugs in man pages and usage messages.
5439 Fixed a number of lint warnings in the ext2fs library and potential
5440 portability problems from other OS's header files that might define
5441 CPP macros for names like "max" and "min".
5443 ext2fs_badblocks_list_add() has been made more efficient when it needs
5444 to grow the bad blocks list.
5446 Fixed a bug in e2fsck which caused it to dereference a freed pointer
5447 just before exiting.
5449 Fixed the substition process for generating the mk_cmds and compile_et
5450 scripts so that they will work outside of the build tree.
5452 Add sanity check to e2fsck so that if an internal routine
5453 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5454 and causing a core dump. This should never happen, but...
5456 E2fsprogs 1.12 (July 9, 1998)
5457 ==================================
5459 E2fsprogs now works with glibc (at least with the version shipped wtih
5460 RedHat 5.0). The ext2fs_llseek() function should now work even with
5461 i386 ELF shared libraries and if llseek() is not present. We also
5462 explicitly do a configure test to see if (a) llseek is in libc, and
5463 (b) if llseek is declared in the system header files. (See standard
5464 complaints about libc developers don't understand the concept of
5465 compatibility with previous versions of libc.)
5467 The ext2fs library now writes out the block group number in each of
5468 the superblock copies. This makes it easier to automatically
5469 determine the starting block group of the filesystem when the block
5470 group information is trashed.
5472 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5473 which means that e2fsprogs will ignore the high 8 bits of the
5474 directory entry's name_len field, so that it can be used for other
5477 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5478 E2fsprogs will now support filesystems with 64-bit sized files.
5480 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5482 Added new program "e2label", contributed by Andries Brouwer. E2label
5483 provides an easy-to-use interface to modify the filesystem label.
5485 Fixed bug so that lsattr -v works instead of producing a core dump.
5487 Fixed a minor bug in mke2fs so that all groups with bad superblock
5488 backup blocks are printed (not just the first one).
5490 Mke2fs will check the size of the device, and if the user specifies a
5491 filesystem size larger than the apparent size of the device it will
5492 print a warning message and ask if the user wants to proceed.
5494 E2fsck has a new option -C, which sends completion information to the
5495 specified file descriptor. For the most part, this is intended for
5496 programs to use, although -C 0 will print a spinning character to the
5497 stdout device, which may be useful for users who want to see something
5498 happening while e2fsck goes about its business.
5500 Fixed a bug in e2fsck which could cause a core dump when it needs to
5501 expand the /lost+found directory, and sometimes the bitmaps haven't
5502 been merged in. Also fixed a related bug where ext2fs_write_dir_block
5503 was used to write out a non-directory block. (Which would be bad on a
5504 non-Intel platform with byte swapping going on.)
5506 Fixed bug in e2fsck where it would print a "programming error" message
5507 instead of correctly identifying where a bad block was in used when
5508 the bad block was in a non-primary superblock or block group
5509 descriptor. Also fixed a related bug when sparse superblocks are in
5510 use and there is a bad block where a superblock or block group
5511 descriptor would have been in a group that doesn't include a
5514 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5515 the block group descriptor table is corrupt, it was possible to try to
5516 allocate a huge array, fail, and then abort e2fsck.
5517 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5518 and subsitutes reasonable values if the descriptors are obviously bogus.
5520 If e2fsck finds a device file which has the immutable flag set and the
5521 i_blocks beyond the normal device number are non-zero, e2fsck will
5522 offer to remove it, since it's probably caused by garbage in the inode
5525 When opening a filesystem, e2fsck specially checks for the EROFS error
5526 code, and prints a specific error message to the user which is more
5529 If the filesystem revision is too high, change the e2fsck to print
5530 that this is either because e2fsck is out of date, or because the
5531 superblock is corrupt.
5533 E2fsck now checks for directories that have duplicate '.' and '..'
5534 entries, and fixes this corruption.
5536 E2fsck no longer forces a sync of the filesystem (with attendant sleep
5537 calls) at all times. The ext2fs_flush() function now performs a sync
5538 only if it needed to write data blocks to disk.
5540 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5541 certain errors would not be properly reported.
5543 Updated and expanded a few points in the man pages which users
5544 complained wheren't explicit enough.
5546 Added special case byte-swapping code if compiling on the PowerPC, to
5547 accomodate the strange big-endian variant of the ext2 filesystem that
5548 was previously used on the PowerPC port.
5554 Removed C++ keywords from the ext2fs libraries so that it could be
5557 E2fsck's internal organization has now been massively reorganized so
5558 that pass*.c don't have any printf statements. Instead, all problems
5559 are reported through the fix_problem() abstraction interface. E2fsck
5560 has also been revamped so that it can be called as a library from a
5563 Added new fileio primitives in libext2fs for reading and writing
5564 files on an unmounted ext2 filesystem. This interface is now used by
5567 Added a new libext2fs function for mapping logical block numbers of
5568 a file to a physical block number.
5570 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5571 a block, zeros it, and updates the filesystem accounting records
5574 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5575 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5577 The libext2fs functions now use a set of memory allocation wrapper
5578 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5579 instead of malloc, free, and resize. This makes it easier for us to
5580 be ported to strange environments where malloc, et. al. aren't
5581 necessarily available.
5583 Change the libext2fs fucntion to return ext2-specific error codes
5584 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5585 and depending on the existence of system error codes (such as EEXIST
5588 Renamed io.h to ext2_io.h to avoid collision with other OS's header
5591 Add protection against ext2_io.h and ext2fs.h being included multiple
5594 The types used for memory lengths, etc. have been made more portable.
5595 In generla, the code has been made 16-bit safe. Added Mark
5596 Habersack's contributed DOS disk i/o routines.
5598 Miscellaneous portability fixes, including not depending on char's
5601 The io_channel structure has a new element, app_data, which is
5602 initialized by the ext2fs routines to contain a copy of the filesystem
5605 ext2fs_check_directory()'s callback function may now return the error
5606 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5607 really do the checking, despite the presence of the callback function.
5610 E2fsprosg 1.11 (June 17, 1997)
5611 ==============================
5613 Fixed e2fsck to detect (previously ignored) conflicts between the
5614 superblock or block group descriptors and block bitmaps, inode
5615 bitmaps, and inode tables.
5617 Fixed bug in e2fsck so that when the message printed out when a block
5618 or inode bitmap conflicts with other data, it has the correct group
5621 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5622 to badblocks. This meant that not all of the filesystem was being
5623 tested for bad blocks!
5625 Fixed an array boundary overrun case which cropped up in
5626 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5629 Adjusted the number of columns printed by mke2fs when displaying the
5630 superblock backups to avoid running over 80 columns when making a
5631 really big filesystem.
5633 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5634 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5635 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5640 Fixed install rule in lib/ss so that ss_err.h is actually getting
5643 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5644 bassed back to the caller.
5646 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5647 setting the current inode number (which meant this function wasn't
5650 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5651 blocks in the bitmap when increasing the size of the bitmap.
5653 Changed the initial number of blocks allocated by ext2fs_init_dblist()
5654 to be more realistic.
5656 Added a new function ext2fs_allocate_group_table, which sets up the
5657 group descriptor information (and allocates inode and block bitmaps,
5658 and inode tables for a particular group). The function was created by
5659 factoring out code form ext2fs_allocate_tables().
5661 Added a new function ext2fs_move_blocks which takes a bitmap of the
5662 blocks to be moved, and moves them to another location on the
5665 Make the unix_io channel's io_channel_flush implementation calls sync()
5666 to to flush the kernel buffers to disk.
5668 Added a new function ext2fs_dblist_count returns the number of
5669 directory blocks in dblist.
5672 E2fsprogs 1.10 (April 24, 1997)
5673 ===============================
5675 Mke2fs once again defaults to creating revision #0 filesystems, since
5676 people were complaining about breaking compatibility with 1.2 kernels.
5677 Warning messages were added to the mke2fs and tune2fs man pages that
5678 the sparse superblock option isn't supported by most kernels yet (1.2
5679 and 2.0 both don't support parse superblocks.)
5681 Added new flag to mke2fs, -R <raid options>, which allows the user to
5682 tell mke2fs about the RAID configuration of the filesystem. Currently
5683 the only supported raid option is "stride" which specifies the width
5686 Fixed bug in e2fsck where pass1b would bomb out if there were any
5687 blocks marked bad in the inode table.
5689 Fixed rare bug in mke2fs where if the user had a very unlucky number
5690 of blocks in a filesystem (probability less than .002) the resulting
5691 filesystem would be corrupt in the last block group.
5693 Fixed bug where if e2fsck tried to allocate a block to fix a
5694 filesystem corruption problem and the filesystem had no free blocks,
5695 ext2fs_new_block() would loop forever.
5697 The configure script now checks explicitly to see if "-static" works,
5698 since that can't be assumed to be true --- RedHat doesn't install
5699 libc-static by default.
5701 Fixed bug in libext2's block iterator functions where under some
5702 cirmcustances, file with holes would cause the bcount parameter to the
5703 callback function to be incorrect. This bug didn't affect any of
5704 e2fsprogs programs, but it was discovered by Paul Mackerras, the
5705 author of the PPC boot loader.
5707 Removed use of static variables to store the inode cache in libext2fs.
5708 This caused problems if more than one filesystem was accessed via
5709 libext2fs (static variables in libraries are generally a bad idea).
5710 Again, this didn't affect e2fsprogs programs, but it was discovered by
5713 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5714 will compile cleanly with 1.2.13 kernels (even with a.out shared
5720 Added new functions to duplicate an ext2 filesystem handle, and its
5721 associated substructure. New functions: ext2fs_dup_handle(),
5722 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5723 Other structures, such as the io_channel and the inode_cache, now have
5724 a ref count so that they only get freed when they are no longer used
5725 by any filesystem handle. (These functions were added as part of the
5726 development effort for an ext2 resizer).
5728 E2fsprogs 1.09 (April 14, 1997)
5729 ===============================
5731 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5732 accidentally introduced in the 1.08 release. The overhead calculation
5733 was accidentally removed, which caused ext2fs_initialize() to not
5734 notice when the filesystem size needed to be adjusted down because
5735 there wasn't enough space in the last block group.
5737 Fixed bug in version parsing library routine; it was always parsing
5738 the library version string, instead of using the passed-in string.
5740 Clarified chattr man page.
5742 E2fsprogs 1.08 (April 10, 1997)
5743 ===============================
5745 E2fsck 1.07 was very slow when checking very large filesystems with a
5746 lot of files that had hard links (i.e., news spools). This was fixed
5747 by seriously revamping the icount abstraction. Added a formal test
5748 suite for the icount abstraction.
5750 Debugfs now has a "-l" option to the "ls" command, which lists the
5751 inode number, permissions, owner, group, size, and name of the files
5754 Fix a bug in e2fsck where when a directory had its blocks moved to
5755 another location during the pass 1b processing, the directory block
5756 list wasn't updated, so pass 2 wouldn't check (and correct) the
5757 correct directory block.
5759 E2fsck will now treat inodes which contain blocks which are claimed by
5760 the filesystem metadata by treating them as multiply claimed blocks.
5761 This way, the data in those blocks can be copied to a new block during
5762 the pass 1b--1d processing.
5764 E2fsck will attempt to determine the correct superblock number and
5765 display it in the diagnostic and warning messages if possible.
5767 Add support for a new (incompatible) feature, "sparse_super". This
5768 feature reduces the number of blocks which contain copies of backup
5769 superblocks and block group descriptors. (It is only an incompatible
5770 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5771 support a new -s option; e2fsck will recognize filesystems built with
5772 this feature turned on.
5774 E2fsck now checks the library to make sure is the correct version,
5775 using new library functions. (This helps to diagnose incorrectly
5776 installed e2fsprogs distributions.)
5778 Dumpe2fs now prints more information; its now prints the the
5779 filesystem revision number, the filesystem sparse_super feature (if
5780 present), the block ranges for each block group, and the offset from
5781 the beginning of the block group.
5783 Mke2fs now distributes the inode and block bitmap blok so that the
5784 won't be concentrated in one or two disks in RAID/striping setups.
5785 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5786 choose the largest blocks per group that be chosen. (For 2k blocks,
5787 you can have up to 16384 blocks/group; for 4k blocks, you can have up
5788 to 32768 blocks/group.) Previously mke2fs would not allow
5789 specification of more than 8192 blocks per group, even if you were
5790 using a 2k or 4k block group.
5795 Added a new function ext2fs_create_icount2() which takes a "hint"
5796 argument. This hint argument presets the icount array with the list
5797 of inodes which actually need to be in the icount array. This really
5798 helps to speed up e2fsck.
5800 Added a new function ext2fs_icount_validate() which checks the rep
5801 invariant for the icount structure. This is used mostly for testing.
5803 The error mesasage given when a bad inode number is passed to
5804 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5805 EXT2FS_UNMARK_ERROR).
5807 Added a new function ext2fs_set_dir_block which sets the block of a
5808 dblist entry, given the directory inode and blockcnt.
5810 Added a new function ext2fs_get_library_version() which returns the
5811 current library version, and ext2fs_parse_version_string() which
5812 returns a version number based on a e2fsprogs version string.
5814 The icount functions will return EINVAL if the passed in inode number
5817 E2fsprogs 1.07 (March 9, 1997)
5818 ==============================
5820 E2fsck is now uses much less memory when checking really large
5821 filesystems (or rather, filesystems with a large number of inodes).
5822 Previously a filesystem with 1 million inodes required 4 megabytes of
5823 memory to store inode count statistics; that storage requirement has
5824 now been reduced to roughly half a megabyte.
5826 E2fsck can now properly deal with bad blocks appearing inside the
5827 inode table. Instead of trying to relocate the inode table (which
5828 often failed because there wasn't enough space), the inodes in the bad
5829 block are marked as in use.
5831 E2fsck will automatically try to use the backup superblocks if the
5832 primary superblocks have a bad magic number or have missing meta-data
5833 blocks (or meta-data blocks which are out of range).
5835 E2fsck's pass 3 has been made more efficient; most noticeable on
5836 filesystems with a very large number of directories.
5838 Completely revamped e2fsck's system of printing problem reports. It
5839 is now table driven, to make them more easily customizeable and
5840 extendable. Error messages which can be printed out during preen mode
5841 are now one line long.
5843 Fixed e2fsck's filesystem swapping code so that it won't try to swap
5844 fast symbolic links or deleted files.
5846 Fixed e2fsck core dumping when fixing a filesystem which has no
5847 directories (not even a root directory).
5849 Added a check to e2fsck to make sure that the length of every
5850 directory entry is a multiple of 4 (since the kernel complains if it
5853 Added a check to e2fsck to make sure that a directory entry isn't a
5854 link to the root directory, since that isn't allowed.
5856 Added a check to e2fsk to now make sure the '.' and '..' directory
5857 entries are null terminated, since the 2.0 kernel requires it.
5859 Added check to write_bitmaps() to make sure the superblock doesn't get
5860 trashed if the inode or block bitmap is marked as being block zero.
5862 Added checking of the new feature set fields in the superblock, to
5863 avoid dealing with new filesystem features that this package wasn't
5866 Fixed a fencepost error in ext2fs_new_block() which would occasionally
5867 try to allocate a block beyond the end of a filesystem.
5869 When the UUID library picks a random IEEE 802 address (because it
5870 can't find one from a network card), it sets the multicast bit, to
5871 avoid conflicting with a legitimate IEEE 802 address.
5873 Mke2fs now sets the root directory's owner to be the real uid of the
5874 user running mke2fs. If the real uid is non-zero, it also sets
5875 the group ownership of the root directory to be the real group-id of
5876 the user running mke2fs.
5878 Mke2fs now has more intelligent error checking when it is given a
5879 non-existent device.
5881 When badblocks is given the -vv option, it now updates the block that
5882 it is currently testing on every block.
5884 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5885 currently correctly if PATH wasn't already set.
5887 Shared libraries now built with dependencies. This allows the shared
5888 library files to be used with dlopen(); it also makes the transition
5889 to libc 6 easier, since ld.so can tell which libc a particular shared
5890 library expects to use.
5895 Added new abstraction (defined in dblist.c) for maintaining a list of
5896 blocks which belongs to directories. This is used in e2fsck and other
5897 programs which need to iterate over all directories.
5899 Added new functions which test to see if a contiguous range of blocks
5900 (or inodes) are available. (ext2fs_*_bitmap_range).
5902 Added new function (ext2_inode_has_valid_blocks) which returns true if
5903 an inode has valid blocks. (moved from e2fsck code).
5905 Added new function (ext2fs_allocate_tables) which allocates the
5906 meta-data blocks as part of initializing a filesystem. (moved from
5909 Added a new I/O manager for testing purposes. It will either allow a
5910 program to intercept I/O requests, or print debugging messages to
5911 trace the activity of a program using the I/O manager.
5913 The badblocks_list functions now store the bad blocks in a sorted
5914 order, and use a binary search to speed up badblocks_list_test.
5916 The inode scan function ext2fs_get_next_inode() may now return a soft
5917 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5918 those cases where part of an inode table is missing or there is a bad
5919 block in the inode table.
5921 Added a new function (ext2fs_block_iterate2) which adds new arguments to
5922 the callback function to return a pointer (block and offset) to the
5923 reference of the block.
5925 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5926 application to jump to a particular block group while doing an inode
5929 The badblocks list functions were renamed from badblocks_* to
5930 ext2fs_badblocks_*. Backwards compatibility functions are available
5931 for now, but programs should be modified to use the new interface.
5933 Some of the library functions were reorganized into separate files to
5934 reduce the size of some programs which statically link against the
5937 Put in some miscellaneous fixes for the Alpha platform.
5940 E2fsprogs 1.06 (October 7, 1996)
5941 ================================
5943 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5944 smash the backup copies in ext2fs_close(). (The problem was that when
5945 e2fsck -p discovered the problem, while it was closing the filesystem
5946 and exiting, it was also blowing away the backup superblocks on the
5947 disk, which was less than friendly.) We now make it the case that we
5948 only write out the backup superblock and the back block descriptors if
5949 the filesystem is completely free from problems.
5951 Fixed a bug in block_interate in the lib/ext2fs library which caused
5952 e2fsck to fail on GNU Hurd-created filesystems.
5954 Add support for Linux/FT's bootloader, which actually uses
5955 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5958 Add support for the "A" (no atime update) attribute. (Note: this
5959 attribute is not yet in production kernels.)
5961 The test suite is not automatically run when doing a "make all" from
5962 the top level directory. Users should manually run "make check" if
5963 they wish to run the test suite.
5965 Upon a preenhalt(), make the printed message more explicit that
5966 running e2fsck "MANAULLY" means without the -p or -a options.
5968 In e2fsck, if a disconnected inode is zero-length, offer to clear it
5969 instead of offering to connect it to lost+found.
5971 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
5972 e2fsck to be run over it, change e2fsck to explicitly display this
5975 For dumpe2fs and e2fsck, cause the -V option to print out which
5976 version of the ext2fs library is actually getting used. (This will
5977 help detect mismatches of using a 1.06 utility with a 1.05 library,
5983 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
5984 the naming convention.
5986 In ext2fs_initialize(), make sure the description for the inode bitmap
5987 is correctly initialize.
5989 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
5991 E2fsprogs 1.05 (September 7, 1996)
5992 ==================================
5994 Add support for new fields in the ext2 superblock --- volume name,
5995 volume UUID, and last mounted field. Dumpe2fs displays these fields,
5996 tune2fs and mke2fs allows you to set them. E2fsck will automatically
5997 generate a UUID for those volumes that don't have them.
5999 Put in support for e2fsck to recognize HURD specific ext2 features ---
6000 most notably, the translator block. The e2fsprogs tools will now use
6001 the creator_os field in the superblock to correctly handle different
6002 OS-specific variants of the ext2 filesystem.
6004 E2fsck now fixes inodes which have a the deletion time set, but which
6005 have a non-zero i_link_count field by offering to clear the deletion
6006 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6007 ext2 kernel behavior) and offered to unlink the file.
6009 If e2fsck sets the clean bit, but nothing else, set the exit code
6010 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6011 set the filesystem valid bit when it was previously cleared. :-) This
6012 was needed to make the HURD fsck driver happy.
6014 If the user refuses to attach an unattached inode, e2fsck will no
6015 longer set the inode's link count. Otherwise, the inode would end up
6016 getting marked as unused, which might cause loss of data later.
6018 Make the message issued by e2fsck when the superblock is corrupt less
6019 confusing for users. It now mentions that another reason for the
6020 "corrupt superblock" message might be that the partition might not be
6021 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6023 Make the libext2 library more robuest so that e2fsck won't coredump on
6024 an illegal superblock where the blocksize is zero. (f_crashdisk is
6027 By default, create filesystems where the default checkinterval is 6
6028 months (180 days). Linux servers can be robust enough that 20 reboots
6029 can be a long, long time.
6031 Added configure flag --enable-old-bitops, which forces the bitops to
6032 use the old (native) bitmask operations. By default on the sparc
6033 platform, the standard ext2 bit ordering is now used.
6035 Added a new feature to e2fsck to byte-swap filesystems; this can be
6036 used to convert old m68k filesystems to use the standard byte-order
6037 storage for the superblock, inodes, and directory blocks. This
6038 function is invoked by using the '-s' option to e2fsck.
6040 Debugfs's "dump" command has been enhanced so that it writes out the
6041 exact size of the file so that the nulls at the end of the file are
6042 eliminated. The command also accept a new "-p" option which will
6043 attempt preserve to preserve the ownernship, permissions, and
6044 file modification/access times.
6046 Debugfs has two new options, -f and -R. The -R option allows the user
6047 to execute a single debugfs command from the command line. The -f
6048 option allows the user to specify a "command file" containing debugfs
6049 commands which will get executed.
6051 Dumpe2fs now pretty prints the check interval, instead of just
6052 printing the check interval as a number of seconds.
6054 Fix bugs in debugfs: the params command when no filesystem is opened
6055 no longer causes a core dump. It is now possible to unlink a file
6056 when a pathame containing a '/' is specified.
6058 Tune2fs has a new -C option which sets the number of times the
6059 filesystem has been mounted.
6061 Fix the chattr '-v' option so that it actually works. Chattr was
6062 being buggy about the -v option parsing.
6067 The directory lib/uuid contains a set of library routines to generate
6068 DCE compatible UUIDs.
6070 Extended ext2fs_namei() to handle symbolic links. Added new function
6071 ext2fs_nami_follow() which will follow last symbolic link in the case
6072 where the pathname points to a sym link.
6074 The ext2fs_block_iterate function will now return the HURD translator
6075 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6076 iterator to return data blocks only. The ext2fs.h file now defines
6077 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6078 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6079 count field of the iterator callback function.
6081 The test script driver now takes an optional second argument, which is
6082 the test case to be run. This allows you to run a test case without
6083 needing to run the entire test suite.
6085 On Linux ELF systems, install the .so files in the correct places
6086 (/usr/lib). The .so files must be stored in the same directory as the
6089 Fixed miscellaneous HURD compilation issues with header file being
6090 included in the right order.
6092 Fixed debugfs so that it resets optind to zero, not one, since setting
6093 optind to zero is more correct.
6096 E2fsprogs 1.04 (May 16, 1996)
6097 =============================
6099 First "official" (1.03 was a limited release only) to support building
6100 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6103 This package includes a RPM specs file, that it can be built using the
6104 RedHat Package Manager.
6106 E2fsck now prints a hint that if there are lots of incorrectly located
6107 inode bitmaps, block bitmaps, and inode table blocks, the user might
6108 want to try using e2fsck -b 8193 first, to see if that fares any
6111 For ext2 filesystem written with the hurd, debugfs will now print out
6112 the translator field when printing an inode structure.
6114 Lots of miscellaneous linking/installation cleanups:
6116 Libraries are now linked using a relative pathname, instead of
6117 relying on -L working correct. It doesn't, in many cases, including
6118 current versions of GNU ld. This guarantees that the build tree is
6119 linking with the right libraries, instead of the ones installed in
6122 Header files, man pages, and the et/ss shell scripts are now
6123 generated using a custom substitution script, instead of relying on
6124 the configure script. This prevents needless recompilation of
6125 files; in addition, the custom substitution script is much faster.
6127 e2fsck may now be linked dynamically, by using the
6128 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6129 since it increases e2fsck's dependence on other files, but some
6130 people need to save disk space, and other critical programs on their
6131 systems were being linked dynamically anyway.
6133 Programs such as fsck which didn't need to be linked against
6134 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6135 only link against libraries they actually need. Otherwise, those
6136 programs would require the presense of libraries that otherwise
6137 could be removed from a rescuse diskette.
6139 The ss include files are now installed correctly so they can
6140 actually be used by another package.
6142 If the profiling libraries are built, they are now installed on a
6143 "make install-libs".
6146 E2fsprogs 1.03 (March 27, 1996)
6147 ===============================
6149 Change the m68k bit numbering for bitmasks to match the bit numbering
6150 used by all other ext2 implementations. (This change was requested by
6151 the m68k kernel development team.)
6153 Support (in-development) filesystem format revision which supports
6154 (among other things) dynamically sized inodes.
6156 Fixed a bug in the ext2 library so that an intelligent error is
6157 returned if mke2fs is run with a ridiculously small number of blocks
6160 Fixed a bug in the ext2 library which required that the device be
6161 openable in read/write mode in order to determine its size. This
6162 caused e2fsck -n to require read/write access when it was not
6163 previously necessary.
6165 Fixed a bug in e2fsck which casued it to occasionally fail the test
6166 suite depending on which version of the floating point library it was
6169 Fixed a bug in e2fsck so that it now halts with a fatal error when
6170 certain superblock consistency checks fail. Previously it continued
6171 running e2fsck, with some potential confusing/damaging consequences.
6173 Added new flag to fsck which allows the root to be checked in parallel
6174 with other filesytems. This is not the safest thing in the world to
6175 do, but some system administrators really wanted it.
6177 Fixed -Wall flames in lib/ss.
6180 E2fsprogs 1.02 (January 16, 1996)
6181 =================================
6183 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6185 Change e2fsck to print statistics of how many non-contiguous files are
6186 on the system. Note that a file which is larger than 8k blocks, it is
6187 guaranteed to be non-contiguous.
6189 In mke2fs, print a warning message if a user tries to format a whole
6190 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6191 whole disk, the -F (force) option forces mke2fs to format a whole disk
6194 Fix a bug in fsck where in some cases it might start checking
6195 partitions in the next pass before it finishes checking partitions in
6196 the current pass. This still won't cause two partitions on the same
6197 disk will be checked, so it's rarely a problem in real life.
6199 Patch lsattr so that it won't hang when checking a named pipe.
6201 Minor compilation fixes:
6202 * Fix the order of libraries that were linked in debugfs.
6203 * Allow the sources to be compiled with -ansi turned on.
