1 E2fsprogs 1.41.13 (November 22, 2010)
2 =====================================
4 E2fsck will open the external journal in exclusive mode, to prevent
5 the journal from getting truncated while it is in use due to a user
6 accidentally trying to run e2fsck on a snapshotted file system volume.
7 (Addresses Debian Bug: #587531)
9 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
12 The tune2fs program can now set the uninit_bg feature without
15 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
16 default mount options settings which were added in 2.6.35.
18 The e2fsck and dumpe2fs programs now support the new ext4 superblock
19 fields which track where and when the first and most recent file
20 system errors occurred. These fields are displayed by dumpe2fs and
21 cleared by e2fsck. These new superblock fields were added in 2.6.36.
23 Debugfs now uses a more concicse format for listing extents in its
24 stat command. This format also includes the interior extent tree
25 blocks, which previously was missing from stat's output for
28 Debugfs has a new option, -D, which will request Direct I/O access of
31 Mke2fs will skip initializing the inode table if a device supports
32 discard and the discard operation will result in zero'ed blocks.
34 Badblocks will now correctly backspace over UTF-8 characters when
35 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
36 Debian Bugs #583782 and #587834)
38 E2freefrag will now display the total number of free extents.
40 Resize2fs -P no longer requires a freshly checked filesystem before
41 printing the minimum resize size.
43 Fixed a floating point precision error in a binary tree search routine
44 that can lead to seg fault in e2fsck and resize2fs.
46 Fixed a bug in e2fsck where if both the original and backup superblock
47 are invalid in some way, e2fsck will fail going back to the original
48 superblock because it didn't close the backup superblock first, and
49 the exclusive open prevented the file system from being reopened.
51 Fixed a big in e2freefrag which caused getopt parsing to fail on
52 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
54 Clarified an mke2fs error message so a missed common in an -E option
55 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
56 results in a more understandable explanation to the user.
58 Mke2fs now displays the correct valid inode ratio range when
59 complaining about an invalid inode ratio specified by the user.
61 Mke2fs now understands the extended option "discard" and "nodiscard",
62 and the older option -K is deprecated. The default of whether
63 discards are enabled by default can be controled by the mke2fs.conf
66 Mke2fs's handling of logical and physical sector sizes has been
67 improved to reflect the fact that there will be some SSD's with 8k and
68 16k physical sectors arriving soon. Mke2fs will no longer force block
69 size to be the physical sector size, since there will be devices where
70 the physical sector size is larger than the system's page size, and
71 hence larger than the maximal supported block size. In addition, if
72 the minimal and optimal io size are not exported by the device, and
73 the physical sector size is larger than the block size, the physical
74 sector size will be used to set the Raid I/O optimization hints in the
77 E2fsck will now display a better, more specific error message when the
78 user enters a typo'ed device name, instead of blathering on about
79 alternate superblocks.
81 Fixed various Debian Packaging Issues
83 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004, #589345)
85 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
86 Polish, Swedish, and Vietnamese translations.
92 Add support for Direct I/O in the Unix I/O access layer.
94 Fixed a memory leak in the Unix I/O layer when changing block sizes.
96 Added a new function to the ext2fs library, ext2fs_get_memalign().
98 The tst_super_size test program will check to make sure the superblock
99 fields are correctly aligned and will print them out so they can be
100 manually checked for correctness.
102 Fixed some makefile dependencies for test programs in lib/ext2fs.
104 Reserved the feature flags and superblock fields needed for the Next3
107 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
108 EXT4_INCOMPAT_EA_INODE.
111 E2fsprogs 1.41.12 (May 17, 2010)
112 ================================
114 Mke2fs now gives a correct error message if the external journal
115 device is not found. (Addresses Red Hat Bug #572935)
117 Resize2fs -P will now refuse to print a minimum size if the file
118 system is not clean. Previously it would go ahead and print a minimum
119 size anyway, which might not be correct, leading to user confusion.
121 E2fsck now tests for extents that begin at physical block 0 and
122 rejects them as invalid. (Addresses Google Bug: #2573806)
124 Fixed a bug in e2fsck which could cause it to crash when trying to
125 remove an invalid extent and the block bitmaps hadn't yet been loaded.
126 (Addresses SourceForge Bug: #2971800)
128 E2fsck now will completely skip time-based checks if the system clock
129 looks insane or the option broken_system_clock is set in
132 E2fsck would previously report an i_blocks corruption for a 4T file
133 created using posix_fallocate; this bug has been fixed.
135 E2fsck will now correctly mark a sparse journal as invalid and will
136 delete and recreate the journal to address the problem.
138 E2fsck would previously incorrectly ask the user whether she would
139 like to abort the file system check after finding a problem --- and
140 then abort regardless of the user's answer. This is annoying, and
143 E2fsck can now continue even if it fails to recreate the resize
144 inode; previously it would just abort the file system check
147 E2fsck could potentially remove directory entries for inodes found in
148 the unused region of the inode table; this would generally happen on
149 ext4 file systems that do not use journaling. This bug has been fixed
150 by not clearing these directory entries once it has been established
151 that bg_unused_inodes may not be trustworthy; once pass #2 has been
152 completed, e2fsck will restart the file system check from the
153 beginning, and then it will be safe to delete any directory entries
154 pointing to inodes that appear to be deleted. (Addresses Google Bug:
157 E2fsck will not try to set the block group checksums if the user
158 cancels the fsck with a control-C. It's a bad idea to set the
159 checksums if e2fsck hasn't been completed, and it often results an the
160 error message, "Inode bitmap not loaded while setting block group
161 checksum info". (Addresses Launchpad Bug: #582035)
163 The mke2fs program now queries the kernel for the physical as well as
164 the logical sector size, and will not allow a blocksize below the
165 logical, and will strongly encourage a blocksize at least as big as
166 the physical blocksize. This is needed for 4k sector drives that
167 emulate 512 byte sector sizes.
169 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
170 rarely needed, but it is a legal value.
172 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
173 not needed, and offer to clear it; this is a sign of a kernel bug, but
174 more importantly, some released kernels may crash when this situation
175 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
177 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
178 i_size is correct. (Kernels starting with 2.6.34 will set
181 The com_err library will now only output ^M (a CR character) when the
184 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
185 and Vietnamese translations.
187 Fixed various Debian packaging issues --- see debian/changelog for
188 details. (Addresses Debian Bugs: #571247, #563487)
194 The regression test suite now uses its own mke2fs.conf file, so that
195 downstream distributions want change the mke2fs.conf file which is
196 distributed in the RPM or dpkg file, without worrying about screwing
197 up the regression test results.
199 Always build namei.o so that building with configure --disable-debugfs
200 works correctly. Long-term, if we care about reduced e2fsprogs
201 builds, we need a more general solution for deciding what .o files are
202 needed for a particular build. Given that install floppies are going
203 (gone?) the way the dodo bird, we probably don't care, though.
204 (Addresses Sourceforge Bug: #2911433)
206 Add configure options --enable-symlink-build and
207 --enable-symlink-install, which allow e2fsprogs be built using
208 symlinks instad of hard links, and to be installed using symlinks
209 instead of hard links, respectively. It is useful when the file
210 system where the build is taking place, or the file system where
211 e2fsprogs is installed, can't handle hard links for some reason.
212 (Addresses Sourceforge Bug: #1436294)
214 Fixed compile warning in mke2fs.c.
217 E2fsprogs 1.41.11 (March 14, 2010)
218 ==================================
220 E2fsck will no longer give a fatal error and abort if the physical
221 device has been resized beyond 2**32 blocks. (Addresses Launchpad
224 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
225 the allocation status of the block <blk>. (Addresses Debian Bug:
228 E2fsck now prints a much more emphatic and hopefully scary message
229 when a file system is detected as mounted while doing a read/write
230 check of the filesystem. Hopefully this will dissuade users from
231 thinking, "surely that message doesn't apply to *me*" :-(
233 E2fsck -n will now always open the file system read-only. We now
234 disallow certain combination of options which previously were manual
235 exceptions; this is bad because it causes users to think they are
236 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
237 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
239 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
240 it detected a badly aligned partition. Unfortunately, this broke some
241 distribution installation scripts, so it now just prints the warning
242 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
243 Launchpad Bug: #530071)
245 Mke2fs would take a long time to create very large journal files for
246 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
249 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
250 2.6.34 kernels to make e2fsck not complain about blocks deliberately
251 fallocated() beyond an inode's i_size.
253 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
254 e2fsck -fD can corrupt non-indexed directories when are exists one or
255 more file names which alphabetically sort before ".". This can happen
256 with ext2 filesystems or for small directories (take less than a lock)
257 which contain filenames that begin with a space or some other
258 punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
265 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
268 The libcom_err function now has support for Heimdal's com_right_r
269 function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
273 E2fsprogs 1.41.10 (February 7, 2010)
274 ====================================
276 Fix resize2fs bug which causes it to access invalid memory.
278 Add libss support for libreadline.so.6.
280 Fix e2fsck's check for extent-mapped directory with an incorrect file
283 Add new e2fsck.conf configuration option, default/broken_system_clock
284 to support systems with broken CMOS hardware clocks. Also, since too
285 many distributions seem to have broken virtualization scripts now,
286 e2fsck will by default accept dates which are off by up to 24 hours by
287 default. (Addresses Debian Bugs: #559776, #557636)
289 Fix a bug where mke2fs may not use the best placement of the inode
290 table when there is only room for a single block group in the last
293 E2fsck is now smarter when it needs to allocate blocks in the course
294 of fixing file system problems. This reduces the number of spurious
295 differences found in pass #5.
297 E2fsck will no longer rehash directories which fit in a single
300 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
301 sparse directories which use extents).
303 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
305 Fix a bug in filefrag where on platforms which can allow file systems
306 with 8k blocks, that it doesn't core dump when it sees a file system
307 with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
310 E2fsck will correctly fix directories that are have an inaccurate
311 i_size as well as other problems in a single pass, instead of
312 requiring two e2fsck runs before the file system is fully fixed.
314 Fix e2fsck so it will correctly find and detect duplicate directory
315 entries for non-indexed directories. ( Addresses Sourceforge Bug:
318 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
319 thinly-provisioned storage device. This can be disabled using the -K
322 Enhance libext2fs so it works around bug in Linux version 2.6.19
323 and earlier where the /proc/swaps file was missing the header on
326 Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
327 was missing the header on the first line.
329 Fix some big-endian bugs in e2fsck and libext2fs.
331 Fix resize2fs so it works correctly on file systems with external
332 journals instead of failing early with the error "Illegal inode
335 Fix libss so that it does not seg fault when using a readline library
336 which does not supply a readline_shutdown() function.
338 Updated dumpe2fs's usage message so it correctly gives the right
339 arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
340 (Addresses Launchpad Bug: #448099)
342 Teach libext2fs to ignore the high 32 bits of the i_blocks field
343 when huge_file file system feature is set, but the inode does not
344 have the HUGE_FILE_FL flag set.
346 Fix e2fsck's handling of 64-bit i_blocks fields.
348 E2fsck will now print "Illegal indirect block", "Illegal
349 double-indirect block", etc., instead of "Illegal block #-1" or
350 "Illegal block #-2", etc. This makes it easier for users to
351 understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
353 Mke2fs now will obtain get device topology information from blkid and
354 use it to populate the superblock stride and stripe sizes. It will
355 also warn if the block device is misaligned
357 Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
360 Fix the libext2fs library code to round up the bitmap size to a 4-byte
361 boundary, to prevent spurious seg faults caused by the x86
362 architecture. This doesn't affect Linux systems, but was a major
363 problem on a number of *BSD systems. (Addresses Sourceforge Bug:
366 Fix resize2fs's minimum size required for a file system so it doesn't
367 fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
369 Dumpe2fs now prints summary information about the contents of the
372 Avoid printing scary error messages when e2fsck starts running
373 problems on low-memory systems, as it tends to panic and mislead the
374 user. (Addresses Debian Bug: #509529)
376 Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
377 modules files. (Address Red Hat Bug: #518572)
379 Fix tune2fs so it can add a journal when an extent-enabled file system
380 is mounted. (Addresses Launchpad bug: #416648)
382 Update Czech, Indonesian, Polish and Vietnamese translations (from the
383 Translation Project).
385 Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
387 Fixed various Debian packaging issues --- see debian/changelog for
388 details. (Addresses Debian Bugs: #540111)
393 The configure script supports the --with-cc, --with-ccopts, and
394 --with-ldopts options. Instead, the more standard use of CC=,
395 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
396 Also, --with-ld, which never worked, was also removed.
397 (Addresses Sourceforge Bug: #2843248)
399 The in-tree header files are only used if the in-tree uuid or blkid
400 libraries are used. Otherwise, use the system-provided uuid or blkid
401 header files if using the system-provided libraries.
403 Fix some build failures caused by --disable-* configure options.
405 Work around a bug in autoconf 2.64.
408 E2fsprogs 1.41.9 (August 22, 2009)
409 ==================================
411 Fix a bug in e2fsck routines for reallocating an inode table which
412 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
413 filesystem feature with a relatively rare (and specific) filesystem
414 corruption. This fix causes e2fsck to try to find space for a new
415 portion of the inode table in the containing flex_bg, and if that
416 fails, the new portion of the inode table will be allocated in any
417 free space available in the filesystem.
419 Make e2fsck less annoying by only asking for permission to relocate a
420 block group's inode table once, instead of for every overlapping
421 block. Similarly, only ask once to recompute the block group
422 checksums, instead of once for each corrupted block group's checksum.
424 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
425 not present, and it needs to fall back to using the FIBMAP ioctl.
427 Fix filefrag to correctly print the number of extents for zero-length
428 files. (Addresses Debian Bug: #540376)
430 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
431 to more easily debug the FIBMAP code.
433 Fixed filefrag for non-extent based files.
435 Add a new program, e2freefrag, which displays information about the
436 free space fragmentation in an ext2/3/4 filesystem.
438 Fix inode resizing via tune2fs -I so that it works correctly in the
439 face of non-empty bad blocks inodes, and if the filesystem was
440 formatted using the "mke2fs -E stride=N" option for RAID arrays.
442 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
443 and corrupt large directories if the directory needs to shrink by more
444 than one block. (Addresses Debian Bug: #537510)
446 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
447 last mount times are in the future, they are corrected even if
448 buggy_init_scripts is set. This is needed because otherwise resize2fs
449 will refuse to resize the filesystem, even after running "e2fsck -f".
450 (Addresses Launchpad bug: #373409)
452 E2fsck will now print much fuller information when the last mount time
453 or last written time is in the future, since most people can't seem to
454 believe their distribution has buggy init scripts, or they have a
455 failed CMOS/RTS clock battery.
457 Enhance dumpe2fs to dump the extent information via the 'stat'
458 command, and more detailed extent information via the new command
461 Update French, Polish, Czech, and Sweedish translation from the
464 Fixed various Debian packaging issues --- see debian/changelog for
470 Fixed miscellaneous gcc -Wall warnings.
472 Fixed memory leak in error path in ext2fs_block_iterate2()
474 Fixed non-Linux build of the intl directory by adding support for the
477 The bitmap read/write functions now treat uninitialized bitmaps as
478 unallocated; this fixes a number of problems in all e2fsprogs for ext4
479 filesystems when there is a need to allocate new blocks or inodes, and
480 there aren't any free blocks or inodes in the already-used block
483 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
484 get inserted into the extent tree when they are not needed.
487 E2fsprogs 1.41.8 (July 11, 2009)
488 ================================
490 Fix resize2fs's online resizing, fixing a regression which in
491 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
493 Fix potential filesystem corruptions caused by using resize2fs to
494 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
497 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
498 setgid and the currently running program doesn't have write access to
499 the uuidd work directory.
501 Add safety checks (for non-Linux systems) so that uuidd isn't run with
502 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
503 will be careful not to close the file descriptor for its unix domain
504 socket when it detaches itself from the controlling tty. Also add
505 safety checks so that if the unix domain socket between the uuid
506 library and uuidd program is closed for any reason, both the library
507 and the uuidd will return an appropriate error code instead of looping
510 The e2croncheck script, which creates an LVM snapshot and then checks
511 the ext3/4 filesystem via the LVM snapshot, has been added to the
514 Fix filefrag program for files that have more than 144 extents.
516 Update French, Polish, Czech, Indonsian, and Sweedish translation from
517 the Translation Project.
519 Fixed various Debian packaging issues --- see debian/changelog for
520 details. (Addresses Debian Bug #535530)
522 Update/clarify man pages.
527 Fix compilation problem when configured with --disable-uuid.
529 Don't build uuidgen if configured with --disable-uuid.
531 Add the new library function ext2fs_test_inode_bitmap_range(), and
532 optimized ext2fs_test_block_bitmap_range(), which will be needed for
533 future optimizations for e2fsck.
535 Fix makefile dependencies for libcom_err so that the Makefiles work
536 well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
538 Enhance the build system so that the full set of commands executed by
539 the Makefiles are displayed, instead of the Linux kernel summary
540 output, if the build was configured with --enable-verbose-makecmds, or
541 if GNU make is in use and the V variable is non-null, i.e., via "make
545 E2fsprogs 1.41.7 (June 29, 2009)
546 ================================
548 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
549 uninitalized data into the portion of the inode beyond the first 128
550 bytes when operating on inodes mapped via extents; potentially
551 corrupting filesystems.
553 Fix memory leaks in e2fsprogs, including a very large memory leak
554 which can cause e2fsck to run out of memory when checking very large
555 filesystems using extents.
557 The logsave program will now filter out the ^A and ^B characters when
558 writing to the console.
560 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
561 end of the block even if the directory block is corrupted.
563 Fix debugfs from core dumping if the logdump command fails to open the
566 Enhance badblocks to print the currently tested block number when
569 Fix lsattr to exit with a non-zero status when it encounters errors.
570 (Addresses RedHat Bugzilla #489841)
572 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
573 filesystems as the kernel when encoding rec_len >= 64k. For 64k
574 filesystems (currently all that is supported by e2fsprogs, this is
575 only a minor corner case).
577 Resize2fs will now update the journal backup fileds in the sup0erblock
578 if the journal is moved; this avoids an unnecessary full fsck after
579 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
581 Fix libext2fs to properly initialize i_extra_size when creating the
582 journal and resize inodes.
584 Change badblocks to allow block sizes larger than 4k.
586 Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
588 Update Chinese and Czech translation from the Translation Project.
590 Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
596 Add --disable-libuuid option to configure which uses an in-system
597 installed version of libuuid; the private version is enabled by
600 Add --valgrind-leakcheck option to the test_script program which runs
601 valgrind with the appropriate options to find memory leaks.
604 E2fsprogs 1.41.6 (May 30, 2009)
605 ===============================
607 Fix a critical regression in e2fsck introduced version 1.41.5 which
608 can undo updates to the block group descriptors after a journal replay.
610 If e2fsck receives an I/O error while replaying the journal, prompt
611 the user whether they want to ignore the error or not; if e2fsck is
612 run in preen mode, force fsck to abort the preen pass.
614 Fix a bug which would cause e2fsck to core dump if the filesystem
615 contains a corrupt extent header, and the user declines to clear the
616 inode. (Addresses Sourceforge Bug: #2791794)
618 Fix e2fsck to restart only once in the case of multiple block groups
619 which inodes in use that are in the uninitialized part of the block
622 To reduce user confusion, if the /etc/mtab file is missing
623 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
624 new, explicit error code to indicate this case. This will cause
625 e2fsck to give a clearer error message when the user is using buggy
626 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
629 Fix e2fsck so that if the primary group descriptors are corrupted, but
630 the backup superblock is entirely invalid, to go back to using (and
631 fixing) the priary group descriptors instead of completely giving up
632 on the filesystem. (Addresses Debian Bug: #516820)
634 Change e2fsck to not abort a preen pass if an inode is found to have
635 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
636 kernels (post 2.6.29) will ignore this field. So let's fix it
637 automatically during the preen pass instead of forcing the user to fix
638 this up manually. (Addresses Debian Bug: #526524)
640 Add resource tracking for e2fsck passes 1b through 1d.
642 Speed up e2fsck by eliminating unnecessary journal checks if the
643 filesystem is already mounted and doesn't need recovery (since the
644 kernel would have run the journal when the filesystem was mounted.)
645 Also speed up e2fsck by avoiding unnecessary block group descriptor
646 updates in ext2fs_close().
648 Add support to chattr to migrate inodes from using direct/indirect
651 Avoid corrupting the filesystem if there is an attempt to shrink a
652 filesystem using resize2fs smaller than posible by making
653 ext2fs_set_bmap() more careful not to delete the old block until the
654 new block can be inserted. In addition, fix a bug in how the minimum
655 size of the filesystem (plus a safety margin) is calculated, and
656 modify resize2fs to refuse to shrink the filesystem below that minimum
657 size without the force flag.
659 Teach blkid to try to figure out DM device names using take advantage
660 of information in sysfs when running on kernels (2.6.29 and later)
661 which provide this information in /sys/block/dm-<N>/dm/name; this is
662 much faster than scanning for the devncie number in /dev/mapper.
664 Fix blkid to prefer /dev/mapper/<name> device names instad of the
665 private /dev/dm-X names.
667 Add an -a option to debugfs's close_filesys command which writes any
668 changes to the superblock or block group descriptors to all of the
669 backup superblock locations.
671 Add support to the filefrag program to use the FIEMAP ioctl.
673 Update Chinese translation from the Translation Project.
675 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
676 Launchpad Bug: #381854)
678 Fixed various Debian packaging issues --- see debian/changelog for
679 details. (Addresses Debian Bug #506064)
685 Add test code to make sure e2fsck's problem.c doesn't have two problem
686 codes assigned to duplicate values.

692 function declaration for init_resource_track() and
693 print_resource_track() when RESOURCE_TRACK is not defined.
695 The test code which is used to build the tst_csum progam has been
696 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
697 avoid compile problems caused by not having a prototype for
698 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)

701 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses

710 =================================
712 Fix a number of filesystem corruption bugs in resize2fs when growing
713 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
716 Debugfs can now set i_file_acl_high via the set_inodes_field command,
717 and print a 64-bit file acl. This is useful for debugging filesystem
718 corruptions where the high bits of i_file_acl_high are set. E2fsck
719 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
720 since some Linux kernel versions pay attention to this field even when
723 Speed up e2fsck when checking clean filesystems by avoiding
724 unnecessary block reads, and coalescing the block group descriptor
725 blocks so they are read using a single read operation.
727 The libuuid library will now close all file descriptors before running
728 uuidd. This avoids problems when the calling program has open sockets
729 which then never get closed because uuidd is a long-running helper
730 daeomn. (Addresses Launchpad bug: #305057)
732 In order to avoid unnecessary full filesystem checks by e2fsck after
733 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
734 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
736 Mke2fs will avoid trying to create the journal when run in
737 superblock-only mode (mke2fs -S), since the left-over journal in the
738 inode table will cause mke2fs to fail.
740 Fix a bug in libext2fs functions that check to see if a particular
741 device or filesystem image is mounted, which would cause these
742 functions to report that a file identical to the (relative) pathname
743 used by a pseudo-filesystem was mounted when in fact it was not.
745 Update Czech translation from the Translation Project.
747 Add Chinese (simplified) translation from the Translation Project.
749 Fix support for external journals (which was broken in e2fsprogs
752 Fix a regression in debugfs where the "stat" command when no
753 filesystem was open would cause debugfs to crash with a segmentation
756 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
757 used to support filesystems without a journal. Update the blkid
758 library so it understands this.
760 The blkid library will remove an entry from the blkid cache
761 representing the entire disk if partitions are found, since presuambly
762 the device previously had no partition table, but has now transitioned
763 to using a partition table.
765 Add a check to mke2fs and tune2fs that the argument to the -m option
766 (which specifies the reserved ratio) must be greater than zero.
767 (Addresses Debian Bug: #517015)
769 Add support for tracking the number kilobytes written to the
770 filesystem via the superblock field s_kbytes_written. It will be
771 updated by the kernel as well as by e2fsprogs programs which write to
772 the filesystem. This is useful for tracking the wear to filesystems
773 on Solid Sstate Drives.

800 ===================================
802 Fixed a bug which could sometimes cause blkid to return an exit value
803 of zero for a non-existent device (Addresses Debian Bug: #502541)
805 Blkid will now recognize ext3 filesystems that have the test_fs flag
806 set as ext3 filesystems.
808 The blkid library will now recognize btrfs filesystems and swap
809 devices currently used by user-level software suspend.
811 Tune2fs now updates the block group checksums when changing the UUID
812 to avoid causing e2fsck to complain vociferously at the next reboot.
814 Tune2fs's inode size resizing algorithms have been fixed so it is not
815 vastly inefficient for moderate-to-large filesystems, due to some
816 O(n**2) and O(n*m) algorithms that didn't scale well at all.
818 Fix tune2fs's inode resizing algorithm so it will not corrupt
819 filesystems laid out for RAID filesystems; in addition, tune2fs will
820 refuse to change the inode size for filesystems that have the flex_bg
821 feature enabled. (This is a limitation in the current implementation
824 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
825 filesystems with 32-bit block numbers, when the headers for 64-bit
826 block numbers was added. This regression has been fixed.
828 Debugfs's ncheck command has been fixed to avoid printing garbage
829 characters at the end of file names.
831 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
832 when shrinking filesystems with uninit_bg feature would not be moved.
833 In addition, blocks and inode table blocks were not being correctly
834 freed when shrinking filesystems with the flex_bg feable, which caused
835 resize2fs -M to fail. Finally, when blocks are moved, make sure the
836 uninitialized flag in extents is preserved.
838 Fix bug which caused dumpe2fs to abort with an error if run on a
839 filesystem that contained an external journal.
841 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
842 for this in argv[0] to provide better legacy support for these
843 distributions. This is a practice that should NOT be continued,
846 Mke2fs now has a new option -U, which allows the user to specify the
847 UUID that should be used for the new filesystem.
849 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
850 minus one block. This allows users who have read that ext3 supports
851 up to 16TB filesystems and who create a 16TB LVM to not get confused,
852 since the true limit is really 16TB minus one block.
854 E2fsck will no longer abort an fsck run if block group has an errant
857 E2fsck now distinguishes between fragmented directories and fragmented
858 files in verbose mode statistics and in the fragcheck report.
860 Fix a bug in e2fsck which casued it double count non-contiguous
863 E2fsck will leave some slack space when repacking directories to allow
864 room for a few directory entries to be added without causing leaf
865 nodes to be split right away.
867 Fix a bug which caused e2fsck to crash when it comes across a
868 corrupted interior node in an extent tree with the error message:
869 "Error1: Corrupt extent header on inode XXXXXX"
871 E2fsck problem descriptions involving the journal are no longer
872 referred to as "ext3" problems, since ext4 filesystems also have
875 Fix a long-standing bug in e2fsck which would cause it to crash when
876 replying journals for filesystems with block sizes greater than 8k.
878 Update Catalan translation from the Translation Project.
880 Fixed various Debian packaging issues --- see debian/changelog for
881 details. (Addresses Debian Bugs: #503057, #502323, #511207)
886 Fix build of e2fsck.profiled, and add support for building profiled
887 binaries in the misc directory if configured with --enable-profile.
889 The ext2fs_open() function now performs more sanity checks on the
890 superblock to avoid potential divide by zero errors by other parts of
893 The ext2fs_read_inode_full() function now has a safety check to avoid
894 a segmentation fault on corrupted filesystems.
896 The ext2fs_new_inode() function now has a sanity check so that if the
897 s_first_inode field in the superblock is insane, it will return
898 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
900 To avoid segmentation faults, ext2fs_block_alloc_stats() and
901 ext2fs_inode_alloc_stats() now validates the passed inode or block
902 number to avoid overrunning an array boundary.
904 Various signed/unsigned errors for variables containing block numbers
907 Accomodations for gcc's stupidity in not realizing that constant
908 strings that do not contain a '%' character are safe to use in format
909 strings have been made so that distributions that want to compile
910 e2fsprogs with -Werror=format-security have an easier time doing so.
912 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
914 Added the utility make-sparse.c to the contrib directory.
916 The ext2fs_block_iterate2() function now reflects errors from
917 ext2fs_extent_set_bmap() to the caller, if the callback tries to
918 change a block on an extent-based file, and ext2fs_extent_set_bmap()
919 fails for some reason (for example, there isn't enough disk space to
920 split a node and expand the extent tree.
922 The ext2fs_block_iterate2() function will preserve the uninit flag in
923 extents when the callback function modifies a block in an extent-based
926 E2fsck will now flag filesystems that have an insane s_first_ino field
927 in their superblock, and attempt to use a backup superblock to repair
931 E2fsprogs 1.41.3 (October 12, 2008)
932 ===================================
934 E2fsck has been fixed so it prints the correct inode number for
935 uinit_bg related problems.
937 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
938 is available on linux. This can be disabled via a configuration
939 option in /etc/e2fsck.conf.
941 Fix a file descriptor leak in libblkid when checking to see if an ext4
942 or ext4dev module exists.
944 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
945 while trying to close a filesystem can lead to infinite loops.
946 (Addresses Red Hat Bugzilla #465679)
948 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
949 will cause resize2fs to drop into an infinite loop. (Addresses Red
950 Hat Bugzilla: #465984)
952 Add a check in the Unix I/O functions in libext2fs so that when a
953 device is opened read/write, return an error if the device is
954 read-only using the BLKROGET ioctl.
956 Fix debugfs's ncheck command so that it prints all of the names of
957 hardlinks in the same directory.
959 Fix a bug in libblkid so it correctly detects whether the ext4 and
960 ext4dev filesystems are available, so that the ext4dev->ext4
961 fallback code works correctly.
966 Fix a parallel build problem by making sure util/subst is built before
967 trying to build the lib/et directory. (Addresses Sourceforge Bug:
970 Updated "make depend" information for crc16.o
973 E2fsprogs 1.41.2 (October 2, 2008)
974 ==================================
976 Fix e2fsck's automatic blocksize detection. This fixes a regression
977 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
978 specifies a block number using the -b option if the blocksize option
979 isn't also specified using -B. Unfortunately, users very commonly
980 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
981 superblock; in fack e2fsck will often suggest this kind of command
984 Enhance the debugfs's "ncheck" command so it will print all of the
985 pathnames for the specified inodes. (Previously, in some cases ncheck
986 might not print a pathname for an inode at all if some of the other
987 inodes had multiple hard links.)
989 Enhance debugfs's "hash" command so the hash seed can be specified via
990 a command-line option. In addition, allow the hash algorithm to be
991 specified by name instead of just by number.
993 Fix e2fsck so that we don't accidentally print the translation file's
994 header when asking the user a custom question so there is no prompt
995 defined for a particular problem record. For example, the question
996 "Run journal anyway" will get the PO header tacked on because e2fsck
997 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1037 theoretical race condition if a multi-threaded application adds and
1038 removes error tables in multiple threads. Unfortunately SuSE's
1039 approach breaks compatibility by forcing applications to link and
1040 compile with the -pthread option; using pthread mutexes has
1041 historically been problematic. We fix this by using sem_post/sem_init

1045 Sourceforge Bug: #2087502)
1047 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
1048 libraries when using ELF shared libraries.

1051 have the e2fsprogs shared libraries already installed. (Addresses
1052 Sourceforge Bug: #2088537)
1054 Fix the pkg-config files so they work correctly when linking with
1055 static libraries and fix the include directory so programs don't have

1057 instead. (Addresses Sourceforge Bug: #2089537)
1059 Make sure ext2fs_swab64() is compiled for all platforms, and not just
1060 for x86. (Addresses Debian Bug: #497515)
1062 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
1063 non-x86 platforms. (They had been removed for x86 earlier.)
1065 Fix diet libc compilation support, which had bitrotted due to lack of
1066 TLC. Fixing this improves general portability.

1069 avoid using absolute pathnames if the link library and the shared
1070 library are installed in the same directory. (Addresses Sourceforge
1073 Fix gen-tarball so it will work even if the top-level directory has

1075 gen-tarball print the size of the resulting tar.gz file.
1078 E2fsprogs 1.41.1 (September 1, 2008)
1079 ====================================
1081 Many people are forgetting to update their mke2fs.conf file, and this
1082 causes ext3, ext4, and ext4dev filesystems won't get created with the
1083 proper features enabled. We address this in two ways. First, mke2fs
1084 will issue a warning if there is not definition for an ext3, ext4, or
1085 ext4dev filesystem and the user is trying to create such a filesystem
1086 type. Secondly, when installing from a source build, "make install"
1087 will provide basic configuration file handling for /etc/mke2fs.conf.
1088 If it exists, and does not mention ext4dev, it will be moved aside to
1089 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1090 be installed. If the existing /etc/mke2fs.conf file does mention
1091 ext4dev, then "make install" will install official mke2fs.conf file as
1092 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1093 they should look to see if any changes need to be merged.
1095 The mke2fs program will now create the journal in the middle of the
1096 filesystem, since this minimizes seek times on average for fsync-heavy
1097 workloads. In addition, mke2fs will now create journals using extents
1098 for filesystems that support them. This results in a more efficient
1099 encoding for the journal since it eliminates the need for using
1102 The mke2fs program will avoid allocating an extra block to the
1103 journal. (Addresses Sourceforge Bug: #1483791)
1105 Mke2fs will correctly enforce the prohibition against features
1106 (specifically read-only features) in revision 0 filesystems. (Thanks
1107 to Benno Schulenberg for noticing this problem.)
1109 Mke2fs previously would occasionaly create some slightly non-optimally
1110 placed inode tables; this bug has been fixed.
1112 The mke2fs and tune2fs programs now print the correct usage message
1113 describing the maximum journal size. (Addresses Debian Bug: #491620)
1115 Add support for setting the default hash algorithm used in b-tree
1116 directories in tune2fs (from a command-line option) or mke2fs (via
1117 mke2fs.conf). In addition, change the default hash algorithm to
1118 half_md4, since it is faster and better.
1120 The blkid library will now recognize MacOS hfsx filesystems, and
1121 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1122 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1124 The blkid library has improved detection of JFS and HPFS filesystems.
1125 (Addresses Launchpad Bug: #255255)
1127 The blkid library is now much more efficiently handling devicemapper
1128 devices, mainly by no longer using the devicemapper library. This can
1129 speed up access for systems with a large number of device mapper
1132 Blkid had a number of cache validation bugs in libblkid that have been
1133 fixed. (Addresses Debian Bug: #493216)
1135 Resize2fs will now properly close out the "updating inode references"
1136 progress bar so there is a newline printed before printing the final
1137 "resize is successful" message.
1139 Resize2fs will now correctly handle filesystems with extents and/o
1140 uninitialized block groups correctly when file/directory blocks need
1141 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1142 is not present). To support this, the ext2fs library now supports
1143 initializing inode and block bitmaps that are not yet initialized when
1144 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1145 addition, e2fs_block_iterate2() can now support changing the location
1146 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1147 been optimized to avoid creating unnecessary new extents when updating
1148 the location of blocks in the extent tree. This will also help out
1149 e2fsck's recovery of obscurely corrupted filesystems with extents,
1150 when blocks are claimed by multiple inodes.
1152 Add support for on-line resizing ext4 filesystem with the flex_bg
1153 filesystem feature. The method for doing so is not optimal, but to do
1154 a better job will require kernel support.
1156 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1157 debugfs programs to not be able to read e2image files; the signed
1158 vs. unsigned bug in the code which read bitmaps from the e2image has
1159 been fixed. (Addresses Debian Bug: #495830)
1161 Resize2fs is now correctly managing the directory in-use counts when
1162 shrinking filesystems and directory inodes needed to be moved from one
1163 block group to another. This bug has been around since e2fsprogs
1164 1.26, and is largely harmless, but does cause a filesystem corruption
1165 which will be flagged by e2fsck after the filesystem has been shrunk.
1167 E2fsck will no longer issue spurious complaints about the inode size
1168 caused by very large extent-based files, and by blocks reallocated
1169 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
1170 Kernel Bugzilla: #11341)
1172 Mke2fs will now set the creation timestamp on the lost+found directory
1173 and the root directory. (More generally, all new inodes created using
1174 the ext2fs library will correctly set the creation timestamp.)
1176 E2fsck now correctly calculates ind/dind/tind statistics in the
1177 presence of extent-based files. In addition, "e2fsck -v" will report
1178 statistics of the depth of extent trees in the filesystem. E2fsck can
1179 also give an inode fragmentation report using "e2fsck -E fragcheck"
1180 which can be useful when debugging the kernel block allocation
1183 Fix support for empty directory blocks in ext4 filesystems with 64k
1184 blocksize filesystems.
1186 E2fsck will now print the depth of corrupt htree directories.
1188 Debugfs's htree command now correctly understands extent-based
1189 directories. It will also print out the minor hash as well as the
1192 Debugfs has a new command which will print the supported features of
1193 e2fsprogs, to enable scripts to know whether the installed version of

1200 small was rather confusing, so it has been improved. Also, we won't
1201 try to create an undo log until we know that command-line-specified
1202 parameters such as "tune2fs -I <inode size>" are valid.
1204 Given some filesystems found "in the wild" that had non-zero block
1205 group checksums even though the uninit_bg/gdt_sum feature was not
1206 enabled, e2fsck would issue spurious error messages. Teach
1207 ext2fs_group_desc_csum_verify() to ignore the block group checksum
1208 entirely if the feature flag is not set. (Addresses Debian Bug:
1211 The blkid program will now print out a user-friendly listing of all of
1212 the block devices in the system and what they contain when given the
1213 -L option. (Addresses Debian Bug: #490527)
1215 The filefrag program now has a more accurate calculation for the
1216 number of ideal extents. (Addresses Debian Bug: #458306)
1218 The test I/O manager is now enabled by default, but its overhead is
1219 only incurred when it would be enabled via the TEST_IO_FLAGS or
1220 TEST_IO_BLOCK environment variables.
1222 Typographical errors in various program strings and usage messages
1223 have been fixed; most of these were pointed out by the e2fsprogs
1224 message catalog translators. (Thanks, translators!)
1226 Update and clarified various man pages, as well as some typographical
1227 errors in the libext2fs texinfo file.

1251 The ext2fs_extent_set_bmap() had some bugs when setting the first
1252 block in a file, or when replacing a single block extent. Those cases
1253 fortunately were came up relatively rarely when e2fsck was checking
1254 files, but caused some problems when resize2fs was shrinking

1260 Various ext2fs library functions --- ext2fs_block_iterate2(),

1265 Ext2ed was failing to build because masix support had been removed in
1266 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
1268 The configure script now respects the LDFLAGS environment variable if
1269 it is set when configure is called. (Addresses Sourceforge Feature
1272 Libuuid is now more portable to the Windows platform. (Addresses
1273 Sourceforge Feature Request: #1937287)
1275 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
1276 bare echo commands so that configure flags such as --quiet work
1277 correctly. (Addresses Sourceforge Patches: #2058794)
1279 A few uses of sprintf have been removed from the ext2fs library to
1280 make life easier for bootloaders with a limited libc environment.

1291 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
1292 top-level Makefile. That automatic rule is used to better support
1293 SCCS, but it caused problems for a particular niche distribution which
1294 likes to use configure.sh files to store the configure options used to
1295 build a package. Unfortuntaely GNU make will use the configure.sh to
1296 replace the configure script, resulting in a self-inflicted fork bomb
1297 leading to an out-of-memory crash.
1299 To support old GNU C compilers don't use C99/C++ comments, but only
1300 K&R style comments, and don't try to use __builtin_expect if __GNUC__
1301 is less than 3. (__builtin_expect is only supported for gcc versions
1302 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
1303 this is an optimization, we only try to use __builtin_expect for gcc 3
1306 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
1307 __LITTLE_ENDIAN, which are only defined by glibc's header files and
1308 hence isn't portable.
1310 For the convenience for some distributions that need a static tune2fs,
1311 the Makefile for misc/ now has a tune2fs.static target.
1313 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
1314 for extent-based files
1316 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
1319 All source files no longer have any trailing white space.
1321 The io_channel_read_blk64() and io_channel_write_blk64() functions are
1322 now functions instead of C preprocessor macros to provide better
1323 forward compatibility.

1332 E2fsprogs is now more portable to Solaris.
1333 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
1335 * Scripts do not assume that /bin/true is always in /bin
1336 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
1337 * Flush stdio handles before calling setbuf(), since Solaris will
1338 discard any pending output to the stream.
1339 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
1340 picky about which C compiler can beused for SUSv3 conformance.
1341 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
1342 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
1343 Since we need some SUSv3 functions, consistently use SUSv3 so
1344 that e2fsprogs will build on Solaris using c99.
1345 * Solaris C99 does not support varargs C preprocessor macros
1346 * Solaris header files pollute the C namespace if in/netinet.h
1347 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
1349 * Solaris ships with a pathetically ancient shell in /bin/sh so we
1350 avoid the use of various more avanced shell constructs such as $().
1352 The "make rpm" command will now take some extra configure optiosn from
1353 the build environment without needing to patch the source tree.
1355 The ext2fs_add_dir_block() function will now grow the dblist more
1356 aggressively as an optimization to avoid copying the array too often.
1358 The e2fsck_write_bitmaps() will write the block and inode bitmaps
1359 together instead of in two passes.
1362 E2fsprogs 1.41 (July 10, 2008)
1363 ==============================
1365 Add support for ext4 filesystem features, in particular extents,
1366 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
1367 support for checking journal checksums. Debugfs will print new
1368 superblock and inode fields that were defined for ext4. For example,
1369 the nanosecond and i_version fields of an inode, and the
1370 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
1371 Note: Resize2fs doesn't currently support the combination of flex_bg
1372 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
1374 Tune2fs can support migrating a filesystem from using 128 byte inodes
1375 to 256 byte inodes, so it can take advantage of the full features of
1378 Add support for "undo" support. E2fsck and mke2fs can optionally
1379 record an undo log which can replayed by the program e2undo.
1381 E2fsck could damage a filesystem by trying to relocate inode tables
1382 due to corrupted block group descriptors, where the attempted inode
1383 table relocation would do far more harm than good. E2fsck has been
1384 fixed to detect this these sorts of corrupted block group descriptors
1385 much earlier in e2fsck processing, so it can try to use the backup
1386 superblock and block group descriptors first. This should be a much
1387 better strategy for recovering these types of corrupted filesystems.
1388 (Addresses Sourceforge Bug: #1840291)
1390 E2fsck will display a more understandable message when the last check
1391 field in the superblock is in the future. (Addresses Debian Bug:
1394 E2fsck now performs more extensive and careful checks of extended
1395 attributes stored in the inode.
1397 Enhance mke2fs to print a more explanatory error message when
1398 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
1401 Fix mke2fs to use a default block size of 4k when formatting an
1402 external journal device. This is done by using a fixed filesystem
1403 type list that consists only of the single filesystem type "journal"
1404 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
1405 Debian Bug: #488663)
1407 Speed up how mke2fs writes the journal data blocks by writing the disk
1408 blocks in larger chunks.
1410 Fix blkid handling of stale devices. Fix a bug which could cause a
1411 core dump while garbage collecting the blkid cache, and assure that
1412 blkid_find_dev_with_tag() never returns a non-existent device. Also,
1413 if a filesystem is found at a new /dev location, eliminate any
1414 duplicate stale entries which can not be verified.
1415 (Addresses Debian Bugs: #487758, #487783)
1417 Add more paranoid checks for LVM volumes and swap partitions in
1418 blkid's probe function, to reduce the chances of false positives.
1420 The mke2fs program now has a much more sophisticated system for
1421 controlling configuration parameters of a newly created filesystem
1422 based on a split filesystem and usage type system. The -t option to
1423 mke2fs was a deprecated alias to -c; it now specifies a filesystem
1424 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
1425 separated usage list. The filesystem type information and type
1426 information is used to extract configuration parameters from the
1427 /etc/mke2fs.conf file.
1429 The mke2fs program will no longer complain and request the -f option
1430 when the user tries to create a filesystem with greater than 2**31
1433 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
1434 adjust the mke2fs.conf file so filesystems for the Hurd are created
1435 with a blocksize of 4096 and inode size of 128, which is all it knows
1436 how to handle. (Addresses Debian Bug: #471977)
1438 Mke2fs will always make sure that lost+found always has at least 2
1439 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
1441 Resize2fs will now print the minimum needed filesystem size if given
1442 the -P option, and will resize the filesystem to the smallest possible
1443 size if given the -M option.
1445 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
1446 blocks are consumed during an off-line resize.
1448 The "ls" command in debugfs now supports the -p option, which causes
1449 it to quote the filenames so that spaces or tabs in directory entries
1450 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
1451 Sourceforge Feature Request: #1201667)
1453 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
1456 The chattr program will return a non-zero exit code in case of
1457 failures, and error messages can be suppressed with the -f option.
1458 (Addresses Red Hat Bugzilla: #180596)
1460 Fix a bug in badblocks which caused it to overrun an array and likely
1461 crash if more than 8 test patterns are specified using the -t option.
1462 (Addresses Debian Bug: #487298)
1464 Add support to badblocks to limit how quickly it reads from the disk
1465 drive (so it can be used for background scrubbing), and so it will
1466 abort after finding a given number of errors.
1468 Remove support for the legacy big-endian filesystem format which only
1469 existed on extremely long-dead PowerPC kernels almost a decade ago.
1471 Remove MASIX support from e2fsprogs.
1473 Add I/O statistics reporting to e2fsck.
1475 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,

1500 Clean up the badblocks group so to make it more portable and robust.
1502 Avoid using predictable filenames in /tmp in blkid's regression test
1503 suite. Also remove bashism's in the regression test script.
1505 If the configure script is given --with-diet-libc, don't use thread
1506 local storage, since diet libc doesn't support TLS. (Addresses
1507 Sourceforge Bug: #2000654)
1509 Fix the blkid regression test suite to tolerate older versions of
1510 mkswap that don't support the -U option.
1512 A few library routines have been converted to support 64-bit block
1513 numbers; in particular, the I/O manager functions, the test_io,
1514 inode_io, and unix_io managers have all be converted to support 64-bit
1517 Debugfs can now be extended for use by test programs. See
1518 lib/ext2fs/extents.c for an example for how it can be used. The test
1519 program links against the debugfs object files, and provides
1520 additional commands by defining an auxiliary libss command table.
1522 The lazy_bg filesystem feature, which was only used by developer's
1523 testing, has been removed since it has been largely supplanted by
1524 uninit_bg. This also simplifies the code.
1527 E2fsprogs 1.40.11 (June 17, 2008)
1528 =================================
1530 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
1531 percentage of reserved blocks. (Addresses Debian Bug: #452639)
1533 Updated Spanish and Catalan translations.
1535 Fixed various Debian packaging issues --- see debian/changelog for
1536 details. (Addresses Debian Bugs: #483962, #483023)

1546 Fix marginal C code in probe_lvm2() function to the blkid library more
1547 portable for older compilers.
1549 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
1551 Fix ext2fs_swap{16,32,64} functions so they can be used by external
1552 applications on big-endian machines. (Addresses Debian Bug: #484879)
1555 E2fsprogs 1.40.10 (May 21, 2008)
1556 ================================
1558 When deciding whether or not to revalidate a blkid cache entry, if the
1559 device's mtime is newer than the last time the cached entry was
1560 validated, force a revalidation.
1562 Fix a potential data corruption bug in e2fsck in the journal replay.
1563 The chances of this is happening is extremely remote, especially the
1564 default data=ordered or data=writeback modes. However, if a block
1565 which has been journalled starts with the first four bytes 0xc03b3998,
1566 when e2fsck replays the journal, those four bytes will be replaced
1567 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
1568 metadata to begin with those fatal 4 byte sequence, and unless
1569 data=ordered mode is in use, data blocks are never journaled.
1571 Updated German, Dutch, Sweedish, and Vietnamese translations.
1576 Fixed various Debian packaging issues --- see debian/changelog for
1579 Remove default sizes of types when cross compiling, since autoconf
1580 2.50 can figure this out automatically now.
1583 E2fsprogs 1.40.9 (April 27, 2008)
1584 =================================
1586 SuSE's security team audited uuidd and came up with a few minor
1587 issues. None of them are serious given that uuidd runs setuid as a
1588 unprivileged user which has no special access other than libuuid
1589 directory, but it's good to get them fixed.
1591 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
1592 work correctly with in-inode extended attributes.
1594 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
1597 Debugfs will avoid using a pager if the standard output is not a tty.
1599 Fix debugfs and tune2fs to correctly handle daylight savings time when
1600 parsing a time string.
1602 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1604 Fix fsck completion bars when multiple filesystems were being checked
1605 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
1606 #203323, Addresses Sourceforge Bug: #1926023)
1608 Fix fsck so that progress information is sent back correctly when
1609 multiple filesystems are being check and the output of fsck is being
1610 redirected to a file descriptor. Also, include the device name (w/o
1611 spaces) in the progress information sent back via a file descriptor.
1612 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
1615 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.

1624 not reported correctly. 9Addresses Launchpad Bug: #220275)
1626 Mke2fs will not allow the logically incorect combination of
1627 resize_inode and meta_bg, which had previously caused mke2fs to create
1628 a corrupt fileystem.
1630 Fix fsck in German locales so that a 'j' means yes.

1637 Fixed various Debian packaging issues --- see debian/changelog for
1640 Update valgrind options in test_script to work with valgrind 3.2.3

1649 Fix build system so that if texinfo is not installed, it won't print a
1650 (harmless) error message.
1653 E2fsprogs 1.40.8 (March 13, 2008)
1654 =================================
1656 Fixed e2image -I so it works on image files which are larger than 2GB.
1658 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
1659 the size is larger than the number of blocks found in the inode, don't
1660 try to allocate extra empty blocks at the end of the directory to make
1661 up the difference; there's no point to doing that. In addition, if
1662 the size is not a multiple of a blocksize, always fix it.
1664 E2fsck handled a pass 2 "should never happen error" by not giving
1665 enough information and then core dumping. Unfortunately, it was all
1666 too easy to trigger the "should never happen" situation if a
1667 directory's inode size was not correct. This has been fixed, but
1668 e2fsck has also been taught how to handle this situation more
1669 gracefully, by simply removing the inode hash tree information, so
1670 that it can be rebuilt again after e2fsck's pass 3. (Addresses
1671 Launchpad Bug: #129395)
1673 Resize2fs had a bug resizing large inodes with extended attributes
1674 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
1675 completely on big-endian systems such as PowerPC. The bug should be
1676 completely fixed now. Yay for regression test suites. (Addresses Red
1677 Hat Bugzilla: #434893)
1679 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
1680 translations. Many thanks to Philipp Thomas from Novell for stepping
1681 up to become the new German translation maintainer! (Addresses Debian
1682 Bugs: #302512, #370247, #401092, #412882).

1685 make it clear that it is just clearing the HTREE information, not the
1688 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1693 Add new functions, ext2fs_dblist_get_last() and
1694 ext2fs_dblist_drop_last(), which allows the caller to examine the last
1695 directory block entry added to the list, and to drop if it necessary.
1697 Fixed a portability problem in libblkid with DJGPP.
1699 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
1700 to Philipp Thomas for pointing this out.
1702 If the info files are not built, change "make install" so it doesn't
1703 fail with an error code.
1706 E2fsprogs 1.40.7 (February 28, 2008)
1707 ====================================
1709 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
1710 depreciate the -s option, since it can result in filesystems which
1711 e2fsck can't fix easily. There are very good reasons for wanting to
1712 disable sparse_super; users who wants to turn off sparse_super can use
1713 debugfs. (Addresses Sourceforge Bug: #1840286)
1715 Add missing options to mke2fs's usage message. (Addresses Sourceforge
1718 Fix bug in resize2fs when large (greater than 128 byte) inodes are
1719 moved when a filesystem is shrunk; it was only moving the first 128
1720 bytes, so extended attributes were not getting moved. (Addresses Red
1721 Hat Bugzilla: #434893)
1723 E2fsck now prints an explicit message when the bad block inode is
1724 updated, to avoid confusion about why the filesystem was modified.
1725 (Addresses Sourceforge Bug: #756460)
1727 Allow mke2fs and tune2fs manipulate the large_file feature.
1728 Previously we just let the kernel and e2fsck do this automatically,
1729 but e2fsck will no longer automatically clear the large_file feature.
1730 It still isn't really necessary to worry about this feature flag
1731 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
1734 Suppress message about an old-style fstab if the fstab file is empty.

1737 Fix (really minor) bug in debugfs's find_free_block so it avoids
1738 reporting a free block more than once if there are too few free blocks
1739 in the filesystem. (Addresses Sourceforge Bug: #1096315)
1741 Change e2fsck to no longer clear the LARGE_FILES feature flag
1742 automatically, when there are no more > 2GB files in the filesystem.
1743 It's been almost a decade since there have been kernels that don't
1744 support this flag, and e2fsck clears it quietly without telling the
1745 user why the filesystem has been changed.
1747 Fix bug which could cause libblkid to seg fault if a device mapper
1748 volume disappears while it is being probed. (Addresses RedHat
1751 Inhance e2fsck's reporting of unsupported filesystem feature flags.

1754 Fix option syntax in dumpe2fs for explicit superblock and blocksize
1755 parameters. What was currently documented in the man page has been
1756 broken for some time, due to getopt() implementation changes. The
1757 option sytax has been changed to one which is can be more portable
1758 supported and which is consistent with the format for extended options
1759 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)

1793 Fixed various Debian packaging issues --- see debian/changelog for
1794 details. (Addresses Debian Bug: #466929)
1796 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
1797 partially filled-in filesystem object on an error, so that e2fsck can
1798 print more intelligent error messages.
1800 Add a new function e2p_edit_feature2() which allows the caller to
1801 specify which feature flags are OK to set or clear, and which returns
1802 more specific information about feature flags which are not allowed to

1838 Added logic to the blkid library to automatically choose whether a
1839 filesystem should be mounted as ext4 or ext4dev, as appropriate.
1841 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.

1866 ===================================
1868 Fix a potential overflow big in e2image if the device name is too
1871 Mke2fs will now create new filesystems with 256 byte inodes and the
1872 ext_attr feature flag by default. This allows for much better future
1873 compatibity with ext4 and speeds up extended attributes even on ext3
1876 Teach e2fsck to ignore certain "safe" filesystem features which are
1877 set automatically by the kernel. Having the kernel set features
1878 automagically behind the user's back is a bad idea, and we should try
1879 to break the kernel of this habit, especially for the newer ext4
1880 feature flags. But for now, we will try to avoid needless full checks
1881 which can annoy users who are doing fresh installs.
1883 Add support in tune2fs and mke2fs for making a filesystem as being "ok
1884 to be used with test kernel code". This will be needed for using test
1885 filesystems with the latest ext4 kernel code.
1887 Change e2fsck -fD so that it sorts non-htree directories by inode
1888 numbers instead of by name, since that optimizes performances much
1889 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
1891 If e2image fills the disk, fix it so it exits right away instead of
1892 spewing large numbers of error messages.
1893 (Addresses-Sourceforge-Feature-Request: #606508)
1895 If ftruncate64() is not available for resize2fs, let it use ftrucate()
1896 instead, but have it check to see if the size would get truncated, and
1897 skip calling ftruncate in that case.
1899 Add support for detecting HFS+ filesystems in the blkid library.
1901 Add supprt in the blkid library for ext4/ext4dev filesystems.
1903 Fix a bug in blkid where it could die on a floating point exception
1904 when presented with a corrupt reiserfs image.
1906 Fix blkid's handling of ntfs UUID's so that leading zeros are printed

1909 Add sample python bindings for the uuid library to the contrib
1910 directory. (Addresses-Sourceforge-Patches: #778817)

1916 Allow the debugfs 'undel' command to undelete an inode without linking

1957 Improve time-based UUID generation. A new daemon uuidd, is started
1958 automatically by libuuid if necessary. This daemon is setuid to allow
1959 updates to /var/lib/libuuid, so the clock sequence number can be
1960 stored and so if the clock is set backwards, it can be detected.
1961 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
1964 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
1965 superblocks. This avoids e2fsck from concluding that a full
1966 filesystem check is required before backing up the superblock due to
1967 changes in the feature flags. (Addresses Debian Bug: #454926)
1969 Fix fsck to only treat the '#' character as a comment at the beginning
1970 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem

2010 ===================================
2012 Fix a potential security vulnerability where an untrusted filesystem
2013 can be corrupted in such a way that a program using libext2fs will
2014 allocate a buffer which is far too small. This can lead to either a
2015 crash or potentially a heap-based buffer overflow crash. No known
2016 exploits exist, but main concern is where an untrusted user who
2017 possesses privileged access in a guest Xen environment could corrupt a
2018 filesystem which is then accessed by the pygrub program, running as
2019 root in the dom0 host environment, thus allowing the untrusted user to
2020 gain privileged access in the host OS. Thanks to the McAfee AVERT
2021 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2023 Fix hueristics in blkid which could cause a disk without partitions to
2024 be incorrectly skipped when a loopback device is present. (Addresses
2025 Red Hat Bugzilla #400321.)
2027 Fix e2image so that in raw mode it does not create an image file which
2028 is one byte too large.
2030 Change mke2fs's usage message so it recommends the preferred -E option
2031 instead of the deprecated -R option.
2033 Enhance the blkid library so it will recognize squashfs filesystems.
2034 (Addresses Red Hat Bugzilla #305151.)
2036 Enhance e2fsck so it will force the backup superblocks to be backed up
2037 if the filesystem is consistent and key constants have been changed
2038 (i.e., by an on-line resize) or by e2fsck in the course of its
2041 Enhance blkid's detection of FAT filesystems; so that USB disks with
2042 only a single bootable partition will not get missed.
2044 E2fsck will no longer mark a filesystem as invalid if it has time
2045 errors (i.e., if superblock mount time or last write time is in the
2046 future) and the user refuses to fix the problem.
2048 The Ubuntu init scripts don't properly set the system time correctly
2049 from hardware clock if the hardware clock is configured to tick local
2050 time instead of GMT time. Work around this as best as we can by
2051 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2052 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2055 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2056 Hat Bugzilla #151533.)
2058 Fix e2fsck so that if the superblock is corrupt, but still looks
2059 vaguely like an ext2/3/4 superblock, that it automatically tries to
2060 fall back to the backup superblock, instead of failing with a hard
2063 Make the e2fsprogs program more robust so that they will not crash
2064 when opening a corrupt filesystem where s_inode_size is zero.
2066 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2067 arguments are detected as such and the parse error is reported to the
2068 user. (Addresses Debian Bug #435381.)
2070 Change e2fsck so it will not complain if a file has blocks reallocated
2071 up to the next multiple of a system's page size.
2073 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2074 about (valid) filesystems where the inode table extends to the last
2075 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2077 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2078 allocating inode tables for some relatively rare odd disk sizes.
2079 (Addresses Red Hat Bugzilla #241767.)
2081 Add Catalan translation and update Dutch and Swedish translations
2082 from the Translation Project.
2084 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
2085 still had an issue when trying to figure out whether we need to
2086 byte-swap fast symlinks that contained extended attributes.
2088 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2089 (Addresses SourceForge Bug #1821333.)
2095 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
2097 Add "make check" to the RPM spec file
2099 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
2100 works correctly when the prefix is not the root directory.
2102 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2103 clena up after themselves by deleting the test.img temporary file
2104 after completing the test.
2106 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2107 first directory entry in a directory block and the last directory
2108 entry in the previous directory block is not in use. Fortunately
2109 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2110 places where it is extremely unlikely to run into this corner case.
2112 Fix missing dependency which would cuase parallel builds to fail.
2113 (Addresses Sourceforge Bug #1842331.)
2115 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2116 calling open(O_CREATE) with a missing mode parameter.
2118 Fix the test_ss.c in lib/ss so it can be used as an example
2119 application program for the library as well as a regression test
2122 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2123 are properly passed back up through the call stack.
2125 E2fsprogs 1.40.2 (July 12, 2007)
2126 ================================
2128 A recent change to e2fsck_add_dir_info() to use tdb files to check
2129 filesystems with a very large number of filesystems had a typo which
2130 caused us to resize the wrong data structure. This would cause a
2131 array overrun leading to malloc pointer corruptions and segfaults.
2132 Since we normally can very accurately predict how big the the dirinfo
2133 array needs to be, this bug only got triggered on very badly corrupted
2136 Fix a bug in e2fsck which caused it to incorrectly salvange
2137 directories when the last entry's rec_len is bogusly too big. This
2138 resulted in a nonsense filesystem corruption to be reported, and
2139 required a second run of e2fsck to fully fix up the directory.
2141 Update tune2fs man page to include more discussion of reserved blocks
2142 (Addresses Launchpad bug #47817)
2144 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2148 E2fsprogs 1.40.1 (July 7, 2007)
2149 ===============================
2151 Fix bug which could cause libblkid to loop forever. When revalidating
2152 a partition where there is obsolete information in /etc/blkid.tab, we
2153 end up freeing a the type tag without clearing dev->bid_type, causing
2154 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2156 The Turkish translation has a bug in it where it has the translation
2157 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2158 @E, recursively, forever, until the stack fills up and e2fsck core
2159 dumps. We fix this by making e2fsck stop @-expansions after a
2160 recursive depth of 10, which is far more than we need.
2161 (Addresses Sourceforge Bug: #1646081)
2163 Compile the default mke2fs.conf into mke2fs program. People are
2164 getting surprised by mke2fs creating filesystems with different
2165 defaults than earlier versions of mke2fs if mke2fs.conf is not
2166 present. So we now create a built in version of mke2fs.conf file
2167 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2168 (Addresses SourceforgeBug: #1745818)
2170 Improve the config/parse_types.sh helper script. Fix a potential
2171 security problem if e2fsprogs is built as root (as Gentoo does!). In
2172 addition fix the script and how it is called from the configure script
2173 so that it does the right thing when cross-compiling. (Fixes Gentoo
2176 Update Vietnamese, French, and Dutch PO files from the Translation
2177 Project. Also created a new e2fsprogs.pot file for translator.
2179 Fix bogus strip permission errors when building under Debian. When
2180 building the e2fsprogs dpkg's, the dh_strip command emits a large
2181 number of error messages caused by the permissions not being right.
2182 So run dh_fixperms before running dh_strip.
2187 Add new function: profile_set_default(). This function sets the value
2188 of the pseudo file "<default>". If the file "<default>" had
2189 previously been passed to profile_init(), then def_string parameter
2190 will be parsed and used as the profile information for the "<default>"
2193 Fix mk_cmds's error reporting so that it is unambiguous that it is the
2194 mk_cmds script which is generating the error. (Obviates Gentoo patch:
2195 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
2197 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
2198 priority" environment variable that overrides all others, where as
2199 LANG is the lowest priorty environment variable. If LC_ALL is set, it
2200 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
2201 the all the rest are set. This will assure that the locale when
2202 running the test suites is the "C" locale. (Obviates Gentoo patch:

2209 Fix divide by zero error in blkid's NTFS probing logic.
2211 Add new blkid -g option which causes the blkid cache to be garbage
2214 Fix a bug in libblkid which could cause the internal field bid_type to
2215 become corrupted. Fortunately bid_type isn't used much, and bid_label
2216 and bid_uuid is only used by debugging code, so the impact of this bug
2219 Mke2fs will now store the RAID stride value when a filesystem is
2220 created with a requested RAID stride, and then use it automatically in
2223 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
2224 isn't too big. In some cases Lustre users have tried specifying an
2225 inode size of 4096 bytes, while keeping an inode ratio of one inode
2228 Improve sanity check in e2fsck's algorithm for finding a backup
2229 superblock, so that it won't accidentally find a superblock that was
2230 located in the journal, and then later reject it as being not a valid
2233 Fix e2fsck get_size logic so that it will work with the Linux floppy
2234 driver. The Linux floppy driver is a bit different from the other
2235 block device drivers, in that if the device has been opened with
2236 O_EXCL, it disallows another open(), even if the second open() does
2237 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
2239 Fix error checking of badblock's last-block and start-block arguments.

2242 Fix e2fsck so that it doesn't overwrite the backup superblocks when
2243 recovering a journal until the master superblock has been confirmed as

2258 Fix e2fsck so that it updates the journal inode if it is corrupted and
2259 the backup journal information from the superblock was successfully
2260 used to recover the filesystem.
2262 Fix e2fsck so that it checks all of the blocks in the journal inode
2263 for validity. The original code only checked the direct blocks to
2264 make sure the journal inode was sane. Unfortunately, if some or all
2265 of the indirect or doubly indirect blocks were corrupted, this would
2268 Add support in blkid to detect LUKS encrypted partitions.
2270 Add extra sanity checks for extended attributes in the case where the
2271 size is zero but the offset is very large.
2273 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
2274 and ext2fs_get_next_inode_full().
2276 Clarify the copyright licenses used by the various libraries in
2277 the top-level COPYING file (Red Hat Bugzilla: 166058)
2279 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
2281 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
2283 Remove check in e2fsck which requires EA's in inodes to be sorted;
2284 they don't need to be sorted, and e2fsck was previously wrongly
2285 clearing unsorted EA's stored in the inode structure.
2287 Allow mke2fs or tune2fs to create a substantially larger journal (up
2288 to 10,240,000 blocks).
2290 Fix MD superblock detection, and make sure the correct UUID is
2291 reported from the MD superblock.
2293 Fix a signed vs. unsigned bug in debugfs.
2295 Enhance debugfs's date parser so that it accepts integer values.

2298 file with multiply claimed blocks is hard linked. or not at all if the
2299 root directory contains shared blocks
2301 Enhance debugfs so it can modify the block group descriptors using the
2302 command set_block_group_descriptor.
2304 Improve e2fsck's reporting of I/O errors so it's clearer what it was
2305 trying to do when an error happens

2326 field on the first pass.
2328 Fix e2fsck to set the file type of the '..' entry when connecting
2329 a directory to lost+found. (Addresses Lustre Bug: #11645)
2331 Enhance e2fsck to recover directories whose modes field were corrupted
2332 to look like special files. This is probably only useful in
2333 artificial test cases, but it will be useful if we ever do the "inodes
2334 in directory" idea for ext4.
2336 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
2339 Fix resize2fs parsing of size parameter (in sector units). This was
2340 actually a bug in libe2p's parse_num_blocks() function. When handling
2341 the 's' suffix, it was ignoring the blocksize information passed in
2342 from the caller and always interpreting the number in terms of a 1k
2343 blocksize. (Addresses Debian Bug: #408298)
2345 There was a floating point precision error which could cause e2fsck to
2346 loop forever on really big filesystems with a large inode count.
2347 (Addresses Debian Bug: #411838)
2349 Fix memory leak in ext2fs_write_new_inode()
2351 Add support for using a scratch files directory to reduce e2fsck's
2352 emory utilization on really big filesystems. This uses the TDB
2353 library. See the [scratch_files] section of the e2fsck.conf man page
2356 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
2357 platform (Addresses Debian Bug: #397044)
2359 Add explanatory message to badblocks that -n and -w are mutually exclusive
2360 (Addresses Debian Bug: #371869)
2362 Allow debugfs and dumpe2fs to support fs features under development.
2364 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
2365 ext2fs_open() , which allows application to open filesystes with features
2366 which are currently only partially supported by e2fsprogs.
2368 Allow unix_io to support offsets greater than 2G (Addresses
2369 SourceForge Bug: #1547922)
2371 Fixed overflow and signed/unsigned problems caused by the number of
2372 blocks or inodes exceeding 2**31 or being close to 2**32-1.
2374 Add support for unsigned directory hash calculations with hints in the
2375 superblock to fix cross-architectural portability for htree
2376 directories with filenames where the high 8th bit is set. (Addresses
2379 Fix resize2fs so that it gives user-intelligible error messages if the
2380 filesystem or the kernel does not support on-line resizing.
2381 (Addresses Debian Bug: #380548)
2383 Require mke2fs -F -F for really dangerous operations, since -F is
2384 needed for less dangerous operations such as creating filesystems
2385 images in regular files, or creating filesystems on whole block
2386 devices. These relatively innocuous usages should NOT be confused
2387 with running mke2fs on an apparently-mounted or in-use filesystem.
2389 Allow the default inode size to be specified into the mke2fs.conf
2392 Make the smallest default journal size is big enough so that on-line
2393 resizing should always work.
2395 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
2398 Fix debugfs coredump when lsdel is run without an open filesystem
2399 (Addresses Debian Bug: #378335)
2401 Fix debugfs display bug us that bytes that have the high bit set are
2402 displayed as "ec" instead of "ffffffec".
2404 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
2406 Device mapper scanning wasn't working in the blkid library because the
2407 pathnames had an extra "/dev" when they were being probed.
2409 Add GFS/GFS2 support to the blkid library.
2411 Fix blkid support of empty FAT filesystem labels.
2413 Avoid recursing forever (or for a long time) when the blkid library
2414 searches for a device and there are symlinks to directories in /dev.
2416 Avoid unaligned halfword access in blkid when accessing FAT
2417 superblocks, as this will cause Sparc/Solaris systems to throw a

2424 Improve the (non-installed, for experts only) findsuper program by
2425 printing the uuid and label from the superblocks, as well as the
2426 starting and ending offsets of the filesystem given the information in
2427 the superblock. Omit by default printing superblocks that are likely
2428 found in located in an ext3 journal unless an explicit -j option is
2431 Updated Spanish, French and Dutch translations and added Catalan
2432 translation. (Addresses Debian bug: #411562)
2434 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
2435 determining a partition's size, since binary searching to determine
2436 the device doesn't work on FreeBSD.
2438 Documentation about UUID's is available in enough places, and it's
2439 awkward to deal with debian-legal's insanities. So I'm caving in the
2440 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
2441 don't have do the dfsg tarball. Also remove the rule that only tried
2442 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
2443 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
2445 Fix the info-dir line so that the menu name does not contain a .info
2446 prefix. First of all, it's ugly, secondly, it causes the install-info
2447 command to fail to remove the com_err info file from the
2448 /usr/share/info/dir file when the comerr-dev package is removed and
2449 purged. (Addresses Debian Bug: #401711)

2462 E2fsck now supports the %It expansion when printing a problem report.
2463 It will print the type of the inode in the problem context.

2466 (Addresses Sourceforge Bug: #1565561)
2468 Remove unused variables and other lint/gcc -Wall cleanups
2470 Add check to ext2fs_get_device_size() so it will return EFBIG for for
2471 filesystems contained in regular files where the filesystem image size
2472 is returned by stat64().
2474 Set local environment variables to C so mk_cmds and compile_et always
2475 work. (Addresses SourceForge Bug: #1532177)
2477 Added the 64-bit byte swapping function ext2fs_swab64().
2479 Added two new helper functions to prevent 2**31/2**32-1 overflow
2480 problems: ext2fs_div_ceil() and e2p_percent().
2482 Create new ext2fs library inline functions ext2fs_group_first_block()
2483 and ext2fs_group_last_block() in order to calculate the starting and
2484 ending blocks in a block group.
2486 Create the generated files read-only to remind developers not to edit them.
2488 Add support for autoconf 2.60 (with backwards compatibility for older
2489 versions of autoconf).
2491 Added an "make rpm" target to top-level Makefile
2493 Added various FreeBSD portability fixes.
2495 Exclude mercurial files from the RPM build tree to speed up copy/build.
2497 Use root_sysconfdir to define the locations of mke2fs.conf and
2498 e2fsck.conf instead of using a hard-coded /etc pathname.
2500 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
2502 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
2504 If diff -u is supported, use it to report test failures.
2506 Updates/improvements to RPM spec file
2508 Add on-disk format definitions for the following new features:
2509 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
2510 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
2511 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
2513 Add a new make target "checked-failed" in the tests directory which
2514 reruns any failed tests
2516 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
2518 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
2519 pointer dereferences, memory leaks, etc. None were security-criticial
2522 Fix up usage and decrement error messages in the test_icount program
2524 Add debugging code to the com_err library; if the environment variable
2525 COMERR_DEBUG is set to 1, print out debugging messages as error tables
2526 are added and removed from the com_err library. If the
2527 COMERR_DEBUG_FILE environment variable is set (and the process is not
2528 setuid) the debugging messages may be redirected to a file.
2530 Change all of the e2fsprogs programs to use the newer add_error_table()
2531 and remove_error_table() interfaces instead of the much older
2532 initialize_*_error_table() function.
2534 Add TDB support into the ext2fs library. This allows us to have a
2535 guaranteed library we can count on always being present so we can
2536 store data in an on-disk database.
2538 Add support for using TDB to store the icount data, so we don't run out
2539 of memory when checking really large filesystems.
2541 Change the regression test suite so that it skips empty test directories.
2543 Define the l_i_iversion field in ext2_inode. The l_i_version field is
2544 now defined from the old l_i_reserved1 field in the ext2 inode. This
2545 field will be used to store high 32 bits of the 64-bit inode version
2548 Add Makefile production rule for e2fsprogs.spec in case it gets
2551 Add new function profile_get_uint() to allow for a clean way to fetch
2552 unsigned integers from the context.
2554 Add test to make sure the ext2 superblock structure is 1024 bytes.
2556 Fix typo in name of f_dup4 regression test
2558 Add new function blkid_gc_cache() which performs a garbage collection
2559 pass on the /etc/blkid.tab file.
2561 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
2562 general, only e2fsck (after the filesystem is clean), tune2fs, and
2563 resize2fs should change the backup superblocks by default. Most
2564 callers of ext2fs_open() should not be touching any superblock fields
2565 which require the backups to be touched.
2567 Add new function to libext2fs, ext2fs_default_journal_size(), which
2568 returns the default journal size.
2571 E2fsprogs 1.39 (May 29, 2006)
2572 =============================
2574 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
2575 between 2**31 and 2**32 blocks.
2577 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
2578 configure the filesystem features, blocksize, and inode_ratio for
2579 different filesystem types.
2581 Mke2fs will now create filesystems hash trees and on-line resizing
2582 enabled by default, based on the new /etc/mke2fs.conf file.
2584 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
2585 filesystem device node in exclusive mode to prevent accidents by
2586 system administrators. In the case of resize2fs and mke2fs, it will
2587 only use exclusive mode if the filesystem is not mounted.
2589 Fixed a bug in mke2fs which caused it to to fail when creating the
2590 resize inode for large filesystems. (Addresses Debian Bug #346580)
2592 When allocating space for the RAID filesystems with the stride
2593 parameter, mke2fs will now place each portion of the group's inode
2594 table right up after the superblock (if present) in order to minimize
2595 fragmentation of the freespace.
2597 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
2598 efficiently by writing the inode and block bitmaps in one pass, thus
2599 reducing the number of disk seeks required.
2601 Add support for on-line resizing to resize2fs.
2603 Fix blkid library so that logic to determine whether or not a device's
2604 cached information in /etc/blkid.tab needs to be verified or not
2605 doesn't get confused by a system clock which is insane (for example,
2606 if the battery is dead on a Macintosh running PPC Linux. (Addresses
2607 Red Hat Bug: #182188)
2609 The blkid library will now store the UUID of the external journal used
2610 by ext3 filesystems, so that in the future, the userspace mount binary
2611 can use this to find the location of the external journal and pass
2612 this information to the kernel.
2614 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
2615 control how various options should be handled. See the e2fsck.conf
2616 man page for more details. (Addresses Debian Bug: #150295)
2618 E2fsck now prints an explanatory message when delaying a filesystem
2619 check when the system is running on battery. (Addresses Debian Bug:
2622 E2fsck will detect if the superblock's last mount field or last write
2623 field is in the future, and offer to fix if so. (Addresses Debian Bug
2624 #327580) These problems will be fixed automatically in preen mode
2625 since Debian's boot sequence bogusly doesn't set the time correctly
2626 until potentially very late in the bootup process, and this can cause
2627 false positives which will cause users' systems to fail to boot.
2628 (Addresses Debian Bugs #343662 and #343645)
2630 E2fsck now checks to see if the superblock hint for the location of
2631 the external journal is incorrect, and if so, offer to update it.
2632 (Addresses Debian Bug: #355644)
2634 Fix e2fsck from segfaulting on disconnected inodes that contain one or
2635 more extended attributes. (Addresses Debian Bug: #316736, #318463)
2637 E2fsck will stop and print a warning if the user tries running a
2638 read/write badblocks test on a read-only mounted root filesystem.
2640 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
2641 C. Thompson for pointing these out; they were originally found using
2644 When resizing a file containing a filesystem, resize2fs will expand or
2645 truncate a file as necessary. (Addresses Debian Bug: #271607)
2647 Resize2fs will now automatically determine the RAID stride parameter that
2648 had been used to create the filesystem, and use that for newly created
2649 block groups. The RAID stride parameter may also be manually specified
2650 on the command line using the new -S option to resize2fs.
2652 Fix mke2fs so that it correctly creates external journals on
2653 big-endian machines (such as a S/390).
2655 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
2656 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
2657 Chambraud for pointing this out.)
2659 Dumpe2fs will now print the size of the journal (if present).
2661 Fix debugfs's set_inode_field command so it can properly set the frag,
2662 fsize, uid_high, gid_high, and author fields in the inode instead of
2663 silently failing, and so that setting the i_size actually sets i_size
2666 Add a new debugfs command, set_current_time, which sets fs->now so
2667 that regression test suites can repeatedly modify the filesystem's
2670 Fix a bug in debugfs's icheck which would incorrectly report the owner
2671 of an extended attribute block.
2673 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
2674 print a usage message when an illegal option character is given.
2676 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
2677 so it won't core dump. (Addresses SourceForge bug #1424311)
2679 Fix mklost+found so that it creates a full-sized directory on
2680 filesystems with larger block sizes.
2682 Fix a file descriptor leak in blkid library.
2684 Fix a display bug in "badblocks -sv" so that the done message properly
2685 clears the block number at the end of the test. (Addresses Debian Bug

2696 that the "best" (i.e., leaf) device is probed by the blkid library.
2698 Fix the blkid library so that it notices when an ext2 filesystem is
2701 Improve the blkid's library VFAT/FAT detection; it now understands
2702 labels stored in the root directory, and is more paranoid about
2703 checking the FAT superblock values.
2705 Fixed a fd leak in the uuid library which was causing problems for the
2706 LVM tools. (Addresses Debian Bug: #345832)
2708 Add support for the reiser4 and software suspend partitions to the
2709 blkid library. Also add support for extract the label from iso9660
2712 Fix a compile_et bug which miscount the number of error messages if
2713 continuations are used in the .et file.
2715 Add extra sanity checks to protect users from unusual cirucmstances
2716 where /etc/mtab may not be sane, by checking to see if the device is
2717 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
2720 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
2721 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
2723 Fix use-after-free bug in e2fsck when finishing up the use of the
2724 e2fsck context structure.

2746 Fixed the Makefile so that they work correctly on newer versions of
2747 GNU make (i.e., 3.81).
2749 Add valgrind support to the regression test suites, and eliminate
2750 false positives from valgrind.
2752 Add a regression test suite for the blkid library.
2754 Fix a fencepost error in resize2fs caught by valgrind.
2756 Fix compiler warnings about missing memcpy prototypes.
2758 We no longer have the sparc assembly code in the header file any more,
2759 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
2760 break compiles on the sparc architectures when using gcc.
2762 In the libext2fs library, add the new field fs->now which if non-zero
2763 is used instead of the system time when setting various filesystem
2764 fields (last modified time, last write time, etc.)
2766 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
2767 ext2fs.h which is needed since the inline functions use memcpy().
2768 (Addresses Sourceforge Bug #1251062)
2770 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
2771 the build system when building files in the util directory which are
2772 needed during the build process. This avoids potential problems when
2773 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
2774 are not recognized as valid by the host compiler. (Addresses
2775 Sourceforge Bug #1261547)
2777 Clean up the blkid library by making the superblock and generic i/o
2778 functions to be more generic. Clean up interface to the probe
2779 function, and fix memory leak. Finallly, remove an unneeded reference
2780 to probe.h in the lib/blkid/resolve.c
2782 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
2783 of invalid block #'s.
2785 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
2786 indicate that the the function read/writes the memory location.
2788 Fix various gcc -Wall complaints.
2790 Add a dependency to make sure that the subdirectories are created
2791 before creating all of the object files, in order to address parallel
2792 build problem in the library Makefiles. (Addresses Sourceforge Bug:
2795 Add $(LDFLAGS) to the command line argument when generating an ELF or
2796 Solaris shared library, to allow cross-compile and other builds that
2797 might need to specify -L paths to needed libraries. (Addresses
2798 Sourceforge Bug #1261549)
2800 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
2801 intended for testing purposes. It allows an ext2/ext3 developer to
2802 create very large filesystems using sparse files where most of the
2803 block groups are not initialized and so do not require much disk
2804 space. Eventually it could be used as a way of speeding up mke2fs and
2805 e2fsck for large filesystem, but that would be best done by adding an
2806 RO_COMPAT extension to the filesystem to allow the inode table to be
2807 lazily initialized on a per-block basis, instead of being entirely
2808 initialized or entirely unused on a per-blockgroup basis.
2810 Fix backwards compatibility so e2fsprogs will better compile on Linux
2813 Make test scripts more robust against locale-related environment variables
2815 Fix type warning problem with sizeof() in ext2fs_open2().
2817 Fix type warning problem with time_t in debugfs.

2821 ==============================
2823 Fix blkid's test programs (built with "make check") compile correctly
2824 even without "configure --enable-blkid-debug".
2826 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
2827 type aliasing rules on newer gcc compilers. (Addresses Red Hat
2830 Fix com_err library to make it more compatible with recent changes
2831 made to the com_err library in MIT Kerberos V5 version 1.4.
2832 (Addresses Sourcefroge Bug #1150146)
2834 General cleanup of messages printed by e2fsprogs programs for grammar,
2835 consistency, and to make life easier for translators. Fixed a few
2836 strings containing English that had not been marked as needing
2837 translations. Removed strings that do not need to be translated, to
2838 make life easier for translators.
2840 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
2841 test to see if a device appears to be in use instead of just relying
2842 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
2844 Fix portability problem in the filefrag program affecting platforms
2845 where the size of an integer is smaller than the size of a long.
2846 (Addresses Debian Bug #309655)
2848 Mke2fs will now use a larger journal by default for filesystems
2849 greater than 4GB. (128 MB instead of 32MB).
2851 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
2852 unless forced. This is to avoid signed vs. unsigned kernel bugs in
2853 block numbers that still need to be fixed.
2855 The blkid program has a new option which will more efficiently search
2856 for device when it is known (or expected) that only one matching
2857 device will be found in the system, such as when doing a lookup by
2860 Debian's e2fsprogs-specific initrd fragment will avoid including
2861 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
2862 and LD_LIBRARY_PATH, and filtering out libraries found in
2863 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
2865 Fixed a potential portability issue in the blkid programs for
2866 architectures where the char type is unsigned. (Addresses Sourceforge
2869 Fix a bug in filefrag so that it doesn't falsely count an extra
2870 discontinuity when the first block found is an indirect block.

2874 able to handle cramfs labels.
2876 Fix debugfs's stat command to not core dump when a filesystem is not

2880 claiming blocks that are also used by other inodes, a filesystem
2881 corruption which was commonly caused by a bug in Fedora Core 3's
2884 Fixed bug in filefrag which caused it to fail on non-ext2/3
2885 filesystems. (Addresses Debian Bug: #303509)
2887 If the superblock last mount time indicates that the system clock may
2888 not be accurate, then e2fsck will omit checking inodes' deletion time

2890 (Previously e2fsck only ommited these LOW_DTIME checks when the
2891 superblock's last write time looked insane.)

2901 and Sourceforge Bug: #1189803)
2903 Updated and fixed translations.
2905 Fixed various Debian packaging issues --- see debian/changelog for
2911 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
2912 changed to take an unsigned int for the bit number. Negative bit
2913 numbers were never allowed (and didn't make any sense), so this should
2914 be a safe change. This is needed to allow safe use of block numbers
2915 greater than or equal to 2**31.
2917 The compile_et program will avoid recreating generated foo_err.c and
2918 foo_err.h files if no changes are necessary. The compile_et program
2919 will also atomically replace these files to avoid a potential parallel
2920 build race problem on SMP systems. (Addresses Sourceforge Bug:
2923 Added a new function to the blkid library, blkid_probe_all_new(),
2924 which only probes newly added disk devices, and change
2925 blkid_find_dev_with_tag() to use this function so that when a
2926 requested tag is not found, devices that were previously not checked
2927 are searched before searching all devices in the system.
2929 Added new functions to the blkid library, blkid_dev_set_search() and
2930 blkid_dev_has_tag().
2932 E2fsck's problem strings can now use @m and @n as abbrevations for
2933 "multiply-claimed" and "invalid", respectively.
2935 The e2fsprog.pot file now has an explanation of how the @-expansion
2936 and %-expansion works, and strings in e2fsck/problem.c which contain @
2937 characters now have comments in e2fsprogs.pot with the @-expansion to
2938 make life easier for translators.
2940 Fixed missing return values in the ext2fs library which could cause it
2941 to return random garbage in certain error conditions.
2943 Allow the current time to be overriden via the E2FSCK_TIME environment
2944 variable for use in regression tests.
2946 The test scrpit driver program now exits with a non-zero status if
2947 there any of its test that it ran failed.
2949 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
2952 Fixed "make check" so that it compiles correctly even when e2fsprogs'
2953 header files have not be installed in the system include directories.
2954 (Addresses Sourceforge Bug: #1180572)
2956 Fixed gcc -Wall nits.
2959 E2fsprogs 1.37 (March 21, 2005)
2960 ===============================
2962 Add support for checking the validity of Extended Attributes stored in
2965 Add support for dumping the contents of large inodes to debugfs,
2966 including the extended attributes stored in inodes.
2968 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
2969 when we create a new inode we make sure that the extra information in
2970 the inode (any extra fields in a large inode and any ea-in-inode
2971 information) is initialized correctly. This can take place when
2972 mke2fs creates the root and lost+found directory, when e2fsck creates
2973 a new root inode or a new lost+found directory, and when the user uses
2974 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
2975 create inode could inherit garbage (or old EA information) from a
2976 previously deleted inode.
2978 Fixed a bug in e2fsck so it would notice if a file with an extended
2979 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
2982 Added support to filefrag to detect files which are using the new
2983 experimental file extents format, and use the non-ext2 algorithm in
2984 that case. Fixed a bug to avoid reporting a false discontinuity if
2985 there is one or more unallocated blocks at the beginning of a file.
2987 Duplicated a check for noticing whether or not the number of blocks
2988 (given a certain blocksize) is greater than 2**32 when the
2989 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
2990 allows mke2fs to automatically use a larger blocksize when creating a
2991 filesystem on a very large device when run on systems that do not
2992 support BLKGETSIZE64.
2994 Fix the I18N build which was broken in e2fsprogs 1.36 because the
2995 build system had been switched to treat the .gmo files as shipped
2996 files (for backwards compatibility with systems that have older GNU
2997 I18N tools installed), but the gen_tarball.in script was still
2998 removing the .gmo files from the official source distribution.
3000 Fixed various Debian packaging issues --- see debian/changelog for
3001 details. (Addresses Debian Bugs ##296769, #299341)
3006 Added new functions to the e2p library which convert between a string
3007 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3008 make the generated binaries more compact.
3010 Fixed a compile-time error on Darwin systems.
3012 Cleaned up the lib/ext2fs Makefile slightly.
3015 E2fsprogs 1.36 (February 4, 2005)
3016 =================================
3018 All of the patches that were applied to Fedore Core 3's
3019 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3020 lot of bug fixes first. Users of Fedora Core 3 are strongly
3021 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3023 Add support for filesystem with the online resizing via resize inode
3024 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3025 patches also didn't bother to do any consistency checking on the
3026 resize inode, or add any tests to the regression test suite. The "-R
3027 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3028 being listed in mke2fs's usage message. All of these shortcomings
3029 have been corrected.
3031 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3032 program. In order to do this, the user must run the commands:
3034 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3035 e2fsck -f /dev/hdXXX
3037 Optionally, the ext2prepare command can be used to re-enable online
3038 resizing after the filesystem has been fixed.
3040 The fsck program will now accept an optional filedescriptor argument
3041 to the -C option. (The Fedora version of this patch would sometimes
3042 cause fsck to ignore a parameter on fsck's command line in some rare
3045 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3048 Make sure resize2fs releases the blocks belonging to the old inode
3049 table blocks when moving the inode table. (Addresses Debian Bug:
3052 Skip the r_resize_inode test if resize2fs is not compiled (due to
3053 configure --disable-resizer)
3055 E2fsck now checks the summary filesystem accounting information, and
3056 if any of the information is obviously wrong, it will force a full
3057 filesystem check. (Addresses Debian Bug #291571)
3059 Fix e2fsck to not complain when the resize_inode feature is enabled,
3060 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3063 Fix e2fsck to note delete symlinks that contain an extended attribute
3064 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3067 Add new utility program, copy_sparse.c, which is very useful
3068 for dealing with large sparse files (such as e2image files).
3070 Add support for jnl_blocks[] for debugfs's set_super_value.
3072 Fix filefrag so that it works correctly with sparse files.
3074 Filefrag -v will print first and last blocks.
3076 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3079 Add mke2fs support so that it can support filesystems larger than 4TB
3080 automatically, by retrying with a 4k blocksize if the device size is
3081 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3084 Change blkid to test for NTFS first because Windows sometimes doesn't
3085 clear enough of the parition to confuse the probing routines into
3086 thinking the old filesystem type is still valid. (Addresses Debian
3089 Add support for swap partition label and uuid's in the blkid library.
3091 Add support to the blkid library to recognize Oracle ASM volumes.
3093 Make blkid -t display all devices that match the specified criteria,
3094 not just the first one, and work more consistently when the blkid
3095 cache file is not available or set to /dev/null. (Addresses Debian
3096 Bug #290530 and #292425)
3098 Badblocks will now correctly display block numbers greater than
3099 999,999,999 in its progress display.
3101 The tune2fs program will not allow the user from setting a ridiculous
3102 number of reserved blocks which would cause e2fsck to assume the
3103 superblock was corrupt. E2fsck's standards for what is a ridiculous
3104 number of reserved block has also been relaxed to 50% of the blocks in
3107 The blkid library will return vfat in preference to msdos, and ext3 in
3108 preference to ext2 (if the journalling flag is set) so that mount will
3109 do the right thing. (Addresses Debian bug #287455)
3111 Mke2fs will now use the -E option for extended options; the old -R
3112 (raid options) option is still accepted for backwards compatibility.
3113 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3115 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3116 (via "32m" or "4g" on the command line) if the user finds this more
3117 convenient than specifying a block count.
3119 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3120 cache conherency problem.
3122 Debugfs now supports a new command, set_inode_field, which allows a
3123 user to manually set a specific inode field more conveniently, as well
3124 as set entries in the indirect block map.
3126 Debugfs's set_super_value command has been enhanced so that the user
3127 can set most superblock fields, including the date/time fields and
3128 some of the more newsly added superblock fields.
3130 E2fsprogs programs now accept an offset to be passed to the file
3131 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3133 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3134 support on the x86 doesn't exist for now, but it can be useful on
3135 other architectures with page sizes greater than 4k. There are 2.6
3136 kernel patches out there which enable this, but they are of this
3137 writing still experimental.
3139 The e2image command now takes the -s option which will scramble
3140 directory entries for raw image files.
3142 Fix a file descriptor leak in the filefrag program.
3144 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3147 Fix bug in debugfs where kill_file would lead to errors when deleting
3148 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3150 Fix bug in the blkid library when detecting the ocfs1 filesystem
3152 Remove obsolete EVMS 1.x and a.out DLL support.
3154 E2fsck will attempt to recover from a journal containing illegal blocks.
3156 Fixed two potential ordering constraint problems in e2fsck which might
3157 cause the filesystem to be corrupted if e2fsck is interrupted during a
3158 (extremely narrow) race window. Thanks to Junfeng Yang from the
3159 Stanford Metacompilation group for pointing this out.
3161 Fixed bug in e2fsck where it would not accurately detect whether or
3162 not the system is running on adaptor if the ACPI device representing
3163 the AC adapter didn't correspond to the what was used on IBM
3166 Change e2fsck to accept directories greater than 32MB.
3168 Fix e2fsck so that a checkinterval of zero disables a time-based check
3171 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
3172 to the PAGER environment variable. (Addresses Debian Bug #239547)
3174 Tune2fs will not mark rewrite the superblock if the feature bitmasks
3177 The debugfs program will set the filetype information when creating a
3180 Add debugfs -d option to use a separate source of data blocks when
3181 reading from an e2image file.
3183 Add e2image -I option which allows the e2image metadata to be
3184 installed into a filesystem.
3186 Fixed bug in the badblocks program which caused "done" to always
3187 appear in english even when a translation was available. (Addresses
3190 The blkid program has a new option -o which controls the output format
3191 of the blkid program; this is makes blkid more convenient to use in
3194 Fix a minor bug in uuid library, which was not using the full 14 bits
3195 of clock sequence when generating UUID's.
3197 Fix a Y8.8888K problem in the uuid library.
3199 Logsave now creates a new session id for itself to avoid getting
3200 killed by init whan transitioning between init levels.
3202 Change the licensing of the UUID library to be the 3-clause BSD-style
3203 license; this allows Apple to use the uuid library in Darwin.
3205 Add ocfs and ocfs2 probe support into the blkid library.
3207 Fix a memory and file descriptor leak in the blkid library.
3209 The blkid library will revalidate the device if the system time is
3210 earlier than last verification time of the device, since that
3211 indicates that the system time is probably nottrustworthy.
3213 The blkid library will override the default location of the blkid.tab
3214 file by the BLKID_FILE environment variable, if it is available.
3216 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
3218 Add various portability fixes for lame new versions of glibc, Darwin
3219 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
3220 Bugs #239934, #264630, #269044, #255589, #289133)
3222 Add support for Windows 9x/NT under Cygwin.
3224 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
3225 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
3227 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
3229 Update the rpm spec files so that it works better with Fedora core 2
3232 Fixed various Debian packaging issues (see debian/changelog). In
3233 particular, fixed the Debian initrd scripts. (#241183, #248050,
3240 Fixed various gcc -Wall warnings.
3242 The uuid library now has new functions uuid_unparse_upper() and
3243 uuid_unparse_lower() which forces the case of the hex digits to be
3244 upper case, or lower case.
3246 The build process has been speeded up by enhancing the subst program
3247 to update the modtime on the generated files even when the generated
3248 file hasn't changed.
3250 The uuid library now uses C99 stdint.h types instead of custom types.
3252 Updated config.guess and config.sub with newer versions from the FSF.
3254 Removed out of date .cvsignore files from the source distribution.
3256 The ext2fs_unlink() function will return an error if both the name and
3257 inode number are unspecified, to avoid doing something surprising
3258 (such as unconditionally deleting the first directory entry).
3259 Directory entries are now deleted by coalescing them with the previous
3260 directory entry if possible, to avoid directory fragmentation. This
3261 is not an issue with the e2fsprogs suite, but may be a problem for
3262 some of the users of libext2fs, such as e2tools.
3264 Add support for version numbers of the form "1.36-rc1".
3266 Fix build of mke2fs.static.
3268 Add basic ext2fs library support for large (EA in inode) inodes.
3270 The test_io mechanism can now abort after n reads or writes to a
3271 particular block. The block is specified by TEST_IO_BLOCK environment
3272 variable, and the read/write count by the TEST_IO_READ_ABORT and
3273 TEST_IO_WRITE_ABORT environment variables. The block data is now only
3274 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
3276 UUID_DEFINE() in the uuid library now creates a static variable, with
3277 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
3278 be used in header files.
3280 Add support for the install-strip and install-shlibs-strip targets, as
3281 suggested by the GNU coding guielines. "make install" no longer
3282 strips the binaries which are installed.
3284 Remove support for the --enable-old-bitops configure option which was
3285 only for very old sparc systems.
3287 Remove support for --enable-clear-htree; this was only needed during
3288 the early development of the htree patch.
3290 Use Linux-kernel-style makefile output so it is easier to see compiler
3293 Update gettext files to version 0.14.1.
3295 Update to use autoconf 2.5x.
3297 Improved support for compiling e2fsprogs under dietlibc.
3299 Make e2fsprogs portable to Solaris and FreeBSD systems.
3301 Add blkid_verify(), blkid_get_library_version(), and
3302 blkid_parse_version_string() functions to the blkid library.
3304 Add pkg-config files for e2fsprogs's libraries.
3306 Fix "make uninstall" to so that it removes everything that is installed.
3308 Add a configure --enable-maintainer-mode option which enables the
3309 makefile rules to rebuild the configure script from configure.in, and
3310 to reubuild the .gmo files in po directory.
3312 Drop the sparc assembly bitwise operations; it's less efficient
3313 than the GCC 3.4 compile code and triggers compiler warnings on
3314 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
3315 (Addresses Debian Bug #232326)
3318 E2fsprogs 1.35 (February 28, 2004)
3319 ==================================
3321 E2fsck has a new -k option, which in conjunction with the -c options,
3322 preserves the existing badblocks list.
3324 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
3326 E2fsprogs will now deal correctly with symlinks that contain
3327 extended attribute information, which can be created using SE Linux.
3328 (Addresses Debian Bug #232328)
3330 Remove a double longjump into an invalid stack frame bug in e2fsck.
3331 (This was during an abort sequence, which normally worked on Linux and
3332 caused a core dump on other operating systems.)
3334 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
3335 (the NLS library will replace "" with the .po header information).
3337 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
3338 dump due to a division by zero error. (Addresses Debian bug #207082)
3340 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
3341 when reconnecting a directory requires creating a lost+found
3342 directory. (Addresses Debian bug #219640).
3344 Fixed a bug where e2fsck would bomb out if a journal needed to be
3345 replayed when using an alternate superblock.
3347 E2fsck will give an extra grace period before actually forcing a check
3348 if the laptop is running on battery. The next time fsck runs while
3349 the system is on the AC mains, or after the grace period is exceeded,
3350 the filesystem will be checked. (Addresses Debian bug #205177)
3352 E2fsck will inform the user when there are 5 or fewer mounts before a
3353 filesystem check will be forced. (Addresses Debian bug #157194)
3355 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
3356 We now correctly handle the case where there is an overlap between a
3357 block group descriptor or a superblock and a bad block indirect block.
3358 In the case where the indirect block is corrupted, we now suggest
3361 Fix byte swap bugs in e2fsck that caused the journal backup location
3362 in the superblock and symlinks created by SE Linux to be cleared
3363 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
3365 E2fsck -c now replaces the current list of bad blocks with the ones
3368 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
3369 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
3371 Fix a potential bug in e2fsck which could cause it to core dump when
3372 trying to print the location of the backup superblock.
3374 Protect against a potential core dump in e2fsck when printing a
3375 message about backup superblocks.
3377 Add support for backing up the journal inode location in the
3378 superblock. E2fsck will automatically save the journal information in
3379 the superblock if it is not there already, and will use it if the
3380 journal inode appears to be corrupted. ext2fs_add_journal_inode()
3381 will also save the backup information, so that new filesystems created
3382 by mke2fs and filesystems that have journals added via tune2fs will
3383 also have journal location written to the superblock as well.
3384 Debugfs's logdump command has been enhanced so that it can use the
3385 journal information in the superblock.
3387 E2fsck will now update all superblocks when moving the journal inode.
3389 Shrink the size of the e2fsck executable by moving some initialized
3390 variables to the BSS segment.
3392 E2fsck will avoid printing the ^A and ^B characters which bracket the
3393 progress bar when stdout and stdin are a tty device instead of a pipe
3394 to another program. (Addresses Debian bug #204137)
3396 Debugfs's mkdir command will automatically expand the directory if
3397 necessary. (Addresses Debian Bug: #217892)
3399 Fixed a bug in debugfs so that copying a file from /dev/null uses the
3400 correct mode bits. (Addresses Debian Bug: #217456)
3402 If the environment variables DEBUFS_PAGER and PAGER are not set,
3403 debugfs now searches for the appropriate pager to use, beginning with
3404 /usr/bin/pager, and then falling back to 'more' and 'less'.
3405 (Addresses Debian bug #221977)
3407 Debugfs will now support 2.6 device numbers where the major or minor
3408 number may be larger than 255. (Addresses Sourceforge bug #865289)
3410 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
3412 Chattr now stops processing options when it sees '--'. (Addresses
3415 Fix regression tests so they work correctly when e2fsprogs is compiled
3416 with configure --disable-htree.
3418 Fix bug in uuid library when there is no network card and the library
3419 is generating a time-based uuid. The random MAC address was not
3420 correctly generated to be a multicast address.
3422 Add compile_et extensions from Heimdall that were missed the first time
3425 Fix bug in badblocks when using O_DIRECT; we need to make sure that
3426 we're reading from an offset which is page aligned. For read-only and
3427 read-write tests, we try to recover after an error so that we can
3428 continue reading on page-aligned boundaries. (Addresses Debian Bug
3431 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
3434 Updated and clarified various man pages. (Addresses Debian Bug
3435 #206845, #222606, #214920, #232406)
3437 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
3439 Fixed various Debian packaging issues (see debian/changelog).
3444 Fixed a build problem so that e2fsprogs would compile with the
3445 --enable-profile option to configure selected. (Addresses Sourceforge
3448 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
3449 Bugzilla Bug #112448)
3451 Centralize code which calculates the location of the superblock
3452 and block group descriptors so that it is in a single library routine.
3454 Added two new functions, ext2fs_file_open2() and
3455 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
3457 Fix compile_et to output the correct prototype for
3458 initialize_xxx_err_table_r() in the header file. (Addresses Debian
3461 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
3463 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
3464 present. This is for when we try stuffing an int into void * pointer.
3466 Fix type-punning which can cause gcc 3.x to miscompile code by getting
3467 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
3468 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
3469 **'. The EVMS code uses an ugly union approach since we don't want to
3470 modify the EVMS interfaces.
3472 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
3473 aid build process on systems can use invoke GNU make as "gmake".
3475 Added regression testing for mke2fs.
3477 Fixed gcc -Wall nitpicks.
3479 Fixed various compiler warnings.
3481 Add portability fixes for FreeBSD and for using fsctl under Darwin to
3482 support ext2 ioctl's.
3485 E2fsprogs 1.34 (July 25, 2003)
3486 ===============================
3488 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
3489 a tight loop while waiting for a child fsck to exit in some cases.
3490 This burns CPU times which slows down the low-level filesystem check.
3492 Added code to mke2fs to assure that the default block size for a
3493 filesystem is at least as big as the sector size of the device, if it
3496 Changed mke2fs and resize2fs to round the default size of a filesystem
3497 to be an even multiple of the VM pagesize in order to avoid a Linux
3498 kernel bug introduced when the storage of the buffer cache was moved
3499 into the page cache.
3501 Mke2fs will warn the user when creating a filesystem with journaling
3502 and a blocksize greater than 4096. (Addresses Debian bug #193773)
3504 Fixed a bug in resize2fs which caused it to fail on filesystems with a
3505 non-empty bad block list. Resize2fs now discards any blocks on the
3506 badblock list which are no longer part of the filesystem as the result
3507 of a filesystem shrink. (Note: this means that shrinking and then
3508 enlarging a filesystem is no longer a reversible operation;
3509 information about bad blocks in the part of the filesystem which is to
3510 be chopped off will be lost.)
3512 Changed resize2fs so the user can use prefixes to specify the units of
3513 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
3514 and to make the error and informational messages explicitly display
3515 the blocksize used by the filesystem, in order to avoid confusion.
3516 (Addresses Debian bug: #189814)
3518 Added a new debugfs command, dump_unused, which dumps the contents of
3519 all unused blocks to stdout. (Useful as an emergency try-to-find
3520 deleted data command.)
3522 Added a new debugfs command, imap, which prints the location of a
3523 specified inode in the inode table.
3525 Fixed a bug in the badblocks program which caused it to use one bit of
3526 randomness in its non-destructive read/write test, instead of using a
3527 full 8 bits of randomness.
3529 Added a new option (-t) to badblocks, which allows the user to control
3530 the test pattern(s) used when checking a disk.
3532 The blkid probe function now more correctly detects UDF filesystems.
3534 Fixed a bug in the blkid library which caused it to not update its
3535 cache if a filesystem changes from having a label to not having a
3538 Fixed a bug in the blkid library wihch could avoid an infinite loop
3539 in blkid_find_dev_with_tag() if /proc is not mounted and there the
3540 /etc/blkid.tab file has not yet been created.
3542 Fixed the badblocks program so that the destructive read/write test
3543 honors the -c option, and to use O_DIRECT when possible to avoid
3544 thrashing the system block buffer cache.
3546 Fixed various NLS issues.
3547 - Added Czech and Swedish translations
3548 - Removed testing NYC translation
3549 - Fixed NLS support for message abbrevations in e2fsck
3550 - Remove de-utf.po, since we shouldn't have two versions using different
3552 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
3553 simplify the statistics reporting in e2fsck.
3555 Changed configure.in so that its defaults for *BSD systems no longer
3556 build an fsck wrapper, and not to install in /usr/local by default.
3558 Fixed some minor spelling errors/typo's in e2fsck and the configure
3561 Fixed various Debian packaging issues (see debian/changelog).
3563 Updated and clarified man pages. (Addresses Debian Bug #195616)
3568 Fix gcc -Wall nitpicks.
3570 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
3571 NLS support by default. (Added partial workaround for gettext/Darwin
3572 incompatibility problems.)
3574 Added full MIT KRB5 and Himdall compaibility support to the com_err
3575 library and the compile_et program. (Addresses Debian bug #191900)
3577 Added the blkid_known_fstype() function to the blkid library, which
3578 returns true if it is passed a filesystem type which is recognized by
3579 the blkid probing functions.
3581 Improved the documentation for the blkid library.
3583 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
3584 returns the hardware sector size of a device, if it is available.
3586 Added a dependency in the blkid library's .so file to the uuid
3587 library, since the former uses the latter. (Addresses Debian bug
3590 Added --with-diet-libc and --disable-evms to the configure script.
3592 Fixed a minor memory leak in the badblocks program.
3594 Fixed a portability problem in tune2fs --- not all systems have strptime().
3596 Fixed a portability problem in debugfs with the use of getopt() more
3597 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
3600 Add support Windows support to ext2fs_get_device_size().
3602 Added (normally disabled) debugging code to the Unix I/O manager which
3603 causes it to disable all userspace caching if the NO_IO_CACHE is
3606 Changed the test I/O manager so it can always be linked into e2fsck,
3607 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
3608 configure script. The test I/O manager will only print any debugging
3609 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
3610 variables are set, which specifies which I/O operations are logged and
3611 a block number to watch, respectively. The log messages are sent to
3612 stderr by default, unless a filename is specified via the
3613 TEST_IO_LOGFILE environment variable.
3616 E2fsprogs 1.33 (April 21, 2003)
3617 ===============================
3619 Added a new utility program, logsave, which captures the output of a
3620 command in a log file, even if the containing directory hasn't been
3621 mounted yet (in which case the it saves the output in memory until it
3622 can write out the logfile). This is useful for capturing the
3623 output of fsck during the boot sequence.
3625 Fixed some portability problems that were causing problems under
3626 the Cygwin32 environment.
3628 Mke2fs now interprets a negative number to the -b option as a minimum
3631 Fixed a bug in mke2fs which was incorrectly checking the argument to
3632 the -g option if the default block size was used. (Addresses Debian
3635 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
3636 it can not find filesystem checkers for jfs, reseirfs, and xfs.
3638 E2fsck now updates the global free block and inode counters from the
3639 block group specific counters quietly. This is needed for an
3640 experimental patch which eliminates locking the entire filesystem when
3641 allocating blocks or inodes; if the filesystem is not unmounted
3642 cleanly, the global counts may not be accurate.
3644 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3645 2.0 is not yet supported; this only pulled in the bug fixes: fixed
3646 possible hangs caused by bugs in calling waitpid, and not setting the
3647 pipe to non-blocking mode; also fixed a file descriptor leak; made
3648 sure all functions call log entry/exit functions.)
3650 Badblocks now flushes its output file as bad blocks are discovered.
3652 The uuid library is now more paranoid about assuming the correctness
3653 of the /dev/random device; it mixes in a stream of bytes from
3654 random/srandom, just in case.
3656 Update Debian files to reflect the fact that I am now the Debian
3657 maintainer of e2fsprogs. Other various Debian-specific packaging
3660 Move the source tarball generation functions from the top-level
3661 makefile to the util/gen-tarball script.
3663 Updated the Turkish .po translation file.
3665 Added Heimdal and MIT krb5 extensions to the com_err library to make
3666 it more compatible with com_err libraries from those distributions.
3668 Changed dumpe2fs to always display the superblock fields relating to
3669 the journalling and/or directory indexing feature even if those
3670 features are not enabled.
3672 Updated and clarify copyright statement vis-a-vis alpha releases of
3675 The ss library will now try to dynamically link to the readline
3676 library and use it if it is present in the system. This means that
3677 the debugfs program now has line editing and history features. The
3678 SS_READLINE_PATH environment variable is used to find a readline or
3679 readline-compatible library.
3681 E2fsck now finds most duplicate filenames (all when rebuilding all
3682 directories via the -D option) and offers to delete or rename
3683 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
3685 Fix bug in e2image. When writing out a raw image file, include data
3686 blocks from symlinks that do not store the symlink within the inode.
3688 Fix bug in resize2fs which incorrectly moved the block and inode
3689 bitmaps for sparse superblock filesystems and incorrectly marked
3690 blocks as in use. (Addresses Debian bug #174766)
3692 Added a new shared library, the blkid library, which efficiently
3693 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
3694 and UUID filesystem specifiers without needing to search all of the
3695 devices in the system. Instead, the device is looked up in a cache
3696 file, and then verified to make sure the blkid cache is correct.
3698 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
3699 the device name, using the blkid library. (Addresses Debian bugs
3702 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
3703 used for spaces in device labels.
3705 Removed 32-bit limitations for debugfs's dump command.
3707 If the user specifies a large number of inodes, Mke2fs will
3708 automatically adjust the number of blocks per group to find a valid
3709 set of filesystem parameters.
3711 Add workaround to detect broken MD devices where when some of the
3712 underlying devices are marked read-only, writes to the MD device are
3713 silently dropped. E2fsck will detect if there is an attempt to run
3714 the journal twice, and abort with an error if this is the case.
3715 (Addresses IBM Bugzilla bug #1226)
3717 E2fsck will print an error if more than one of the -p/-a, -n or -y
3718 options are specified.
3720 E2fsck will fix HTREE corruptions in preen mode, without stopping the
3721 boot process. This is needed because the 2.4 ext2 filesystem
3722 accidentally had the INDEX_FL backwards compatibility code removed.
3724 Mke2fs no longer creates filesystems with the dir_index flag set by
3725 default; the user has to specifically request it.
3727 Update and clarified various man pages. (Addresses Debian bugs
3728 #173612, #175233, #175113, and #170497, #185945, #188318)
3730 Created man page for the mk_cmds program (from the libss library).
3735 Fix various gcc -Wall nits.
3737 Fixed a lot of portability problems that caused e2fsprogs not to build
3738 successfully under Solaris and Apple/Darwin.
3740 Fixed a Makefile dependency to allow building e2fsprogs using parallel
3743 Changes to create a subset distribution which consists only of the
3744 et, ss, uuid, and blkid libraries. The configure script and top-level
3745 makefile were changed to support working with a subset distribution.
3747 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
3748 actually used, and might people who are looking for
3749 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
3751 Updated debian files to fix a number of Lintian warnings.
3753 Updated config.guess and config.sub with newer versions from the FSF.
3755 Removed unnecessary libraries from being linked into the fsck, lsattr,
3756 chattr, and blkid executables.
3758 E2fsprogs 1.32 (Nomvember 9, 2002)
3759 ==================================
3761 Fixed a bug in the Unix I/O routines which caused needless writebacks
3762 of clean blocks from the unix_io cache (they were erroneously marked
3763 as being dirty, so they were getting written back to disk before
3764 getting evicted from the disk cache). This was harmless, but it
3765 significantly slowed down e2fsck.
3767 Made some other minor optimizations to the Unix I/O routines to save a
3768 small amount of CPU time.
3770 Updated internationalization files.
3773 E2fsprogs 1.31 (Nomvember 8, 2002)
3774 ==================================
3776 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
3777 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
3778 handling for child process that die unexpectly. Add a hack to force
3779 mkfs to create filesystems that won't cause problems with hardware
3780 that has 2k or 4k minimum blocksize requirements. Read from child
3781 processes in non-blocking mode, so that the GUI continues to update.
3783 Fix e2fsck so that it returns the appropriate exit code when the root
3784 filesystem has been changed, so that system's rc scripts will be told that
3785 the system needs to be rebooted.
3787 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
3788 was set, some of the descriptor blocks that should have been written
3789 out were getting skipped.
3791 Changed e2fsck to force out changes to the backup copies of the
3792 superblock and block group descriptors when important changes are made
3793 to those data structures.
3795 Fix a bug where e2fsck could erroneously mark a filesystem as being
3796 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
3797 introduced in e2fsprogs 1.28.)
3799 If journal debuging is enabled using --enable-jbd-debug, the debugging
3800 level is now set via the E2FSCK_JBD_DEBUG environment variable.
3802 If byteswapping support is disabled using configure --disable-swapfs,
3803 skip the tests which depend on byte-swapping, so that "make check"
3806 Lshattr will now display the indexed directory flag. Also, some of
3807 the more esoteric compression flags are supressed unless compression
3808 support has been enabled.
3813 E2fsprogs 1.30 (October 31, 2002)
3814 =================================
3816 When resizing a filesystem, and inodes need to moved, resize2fs will
3817 update the inode's ctime field, and the mtime field of the containing
3818 directories, so that incremental backups using dump/restore will work
3821 In order to avoid spurious errors, e2fsck wil check the last
3822 superblock write time to determine whether or not it can safely use
3823 the LOW_DTIME checks to determine if there are inodes on the orphan
3824 inode linked list that had somehow gotten disconnected. (Addresses
3825 Sourceforge bug #620980)
3827 Partition in /proc/partitions that being with the string "lvm" are
3828 considered real partitions even if they do not end with a number.
3830 Fixed a bug in the the uuid generation function, where if /dev/urandom
3831 is not present, but /dev/random is, and there isn't sufficient
3832 entropy, the get_random_byte function could spin a loop forever.
3834 E2fsck, mke2fs, etc. will now reliably notice when image files are
3835 mounted using the loopback interface. (Addresses Sourceforge bug
3838 When flushing buffers (as is done by badblocks, for example) check to
3839 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
3840 FDFLUSH ioctl which causes the MD device driver which causes confusing
3841 syslog messages about obselete ioctl messages. (Addresses Sourceforge
3844 Debugfs's write command now checks to see if the destination filename
3845 exists before creating it. (Addresses Sourceforge bug #478195.)
3847 When installing man pages, search for compressed man pages using all
3848 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
3850 Fixed a bug in fsck where multiple filesystems specified on the
3851 command were not being checked in parallel due to a logic bug
3852 introduced to support the FSCK_MAX_INST environment variable.
3854 We have added a new superblock field, s_mkfs_time, which indicates
3855 when a filesystem was created. It is set via mke2fs, and printed out
3856 by dumpe2fs, but is not actually touched by the kernel.
3858 Dumpe2fs has been made more robust by not aborting if there is an
3859 error reading the block/inode bitmaps; instead it will still print out
3860 the location of the block/inode bitmaps and inode table.
3862 Add support for the an alternative block group descriptor layout which
3863 allows for on-line resizing without needing to prepare the filesystem
3864 in advance. (This is the incomat feature flag meta_bg.)
3866 Add support for storing default mount options in the superblock, so
3867 that the filesystem can be mounted with specific mount options without
3868 needing to specify them on the mount command line or in the /etc/fstab
3871 Add support for a new inode flag, which is to be used for indicating
3872 the top of directory hierarchies for the Orlov block allocator.
3874 Fix e2fsck so that if it creates the lost+found directory, it does so
3875 with the more apporpriate permissions of 0700. Also change
3876 mklost+found so that it also creates the directory 0700.
3878 Fixed format bug in e2fsck if NLS is in use.
3880 Add a German translation for e2fsprogs's NLS support.
3882 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
3883 the beginning of the inode table. This won't matter much, since if
3884 there is a bad block at the beginning of the inode table, the root
3885 directory won't be available. But at least e2fsck won't crash in this
3888 Fixed endian problems in the htree code for e2fsck and debugfs.
3890 When byte-swapping a filesystem on a PPC architecture, byte-swap the
3891 bitmaps since the historical big-endian ext2 variant had byte-swapped
3892 bitmaps, and the ext2fs library assumes this. This fixes the
3893 regression test suite on PPC machines.
3895 Fix e2image so that it handles a bad block in the inode table
3898 E2fsck now uses a more sophisticated algorithm to salvage corrupted
3899 directories that recovers more information in the corrupted directory
3902 E2fsck now performs additional consistency checks on indexed (HTREE)
3905 Fix bug where efsck might get confused about whether a completely
3906 empty directory block is an empty leaf block or an interior htree
3907 node. This could cause e2fsck to get confused into think that a valid
3908 indexed directory was corrupted.
3910 E2fsck no longer creates an empty directory entry at the end of a
3911 directory block when optimizing a directory. This would cause some
3912 earlier versions of the dxdir kernel code to corrupt the directory
3913 when attempting to split a node containing an empty directory entry.
3915 E2fsck could sometimes in rare circumstances leave the indexed flag
3916 set after a small directory was optimized by compressing it instead of
3917 indexing it. (This should never happen in real life, since
3918 directories that small wouldn't have been indexed, but better safe
3921 E2fsck now only updates the master superblock in all cases. This
3922 slightly shortens its run time.
3924 Ext2ed can deal with directory entries of length 0; previously it
3925 would get stuck in an infinite loop.
3927 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
3928 specifiers. (Sourceforge patch #613447)
3930 Badblocks will now work correctly on read-only devices such as
3931 CD-ROM's. (Sourceforge patch #600451)
3933 Updated and clarified man pages. (Addresses Debian bug #167108)
3936 E2fsprogs 1.29 (September 24, 2002)
3937 ===================================
3939 Fixed a bug in e2fsck which could corrupt a directory when optimizing
3940 it (via the -D option) or rebuiliding the hash tree index with a 1 in
3941 512 probability, due to a fence post error.
3943 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
3946 Mke2fs now enables the directory indexing flag by default. (Since
3947 this is a compatible feature flag, it's safe to do so.)
3949 Tune2fs will support setting the directory indexing feature flag. It
3950 will automatically set up the default hash algorithm and hash seed
3951 fields in the superblock.
3953 If the bone-headed user enters the root filesystem twice in
3954 /etc/fstab, the -R option which skips the root filesystem will skip
3955 all of them. (Addresses Debian bug #159423). Note! This is not a
3956 precedent for dealing intelligently with any other kind of doubled
3957 entry in /etc/fstab!
3963 Removed perror declaration in lib/et/internal.h. All modern systems
3964 can be expected to define perror() these days. Besides, the lib/et
3965 code wasn't using perror at all anyway. :-)
3968 E2fsprogs 1.28 (August 31, 2002)
3969 ================================
3971 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
3972 for setting the htree flag is not included yet, although it can be
3973 manually turned on via the debugfs program.
3975 Clarified e2fsck error message which is printed when it cannot find
3976 sufficient contiguous block when relcating filesystem metadata.
3978 Added support for building an EVMS plugin module for ext2/3. This
3979 module is substantially the same as the EVMS module shipping with EVMS
3980 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
3981 for use with EVMS 1.0 (which did not include the ext2 plugin module),
3982 if the configure --enable-old-evms flag is given.
3984 Fsck will search through EVMS volumes when trying to resolve
3985 filesystem specifications such as LABEL=xxx or UUID=xxx.
3987 Added a new utility program, /sbin/findfs, which will return
3988 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
3991 Update and clarified various man pages. (addresses Debian Bug #145044,
3992 #146437, #131350, #151990, #144621, #141938)
3994 If there are no filesystems specified on fsck's command line, fsck now
3995 treat that as if the -As options were given. Previously it would
3996 simply do nothing. (Addresses Debian Bug #153102)
3998 Mke2fs no longer treats a failure to be able to clear the MD signature
3999 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4002 The e2p library functions (which are used by lsattr and chattr) now
4003 double check to make sure the file is a regular file or directory
4004 before attempting to use the ext2 ioctls. Some device drivers
4005 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4006 (Addresses Debian Bug #152029).
4008 The extended attribute handling has been updated to correspond with
4009 the latest V2 bestbits ACL code.
4011 Fixed bug in e2fsck which caused it to not clear the dtime field when
4012 processing truncated inodes on the orphan list. This could cause data
4013 loss(!) if a filesystem is rebooted before a truncate has been
4016 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4017 algorithms. This makes e2fsck much faster in the case of severely
4018 corrupted filesystems where a large number of blocks are claimed by a
4019 large number of inodes. (Thanks to the 2.5 IDE device driver for
4020 inspiring this work.)
4022 Resize2fs has been significantly sped up when shrinking and expanding
4023 a filesystem by a very small number of blocks (for example, when EVMS
4024 is converting a partition to be an EVMS legacy volume).
4026 Added a new option to e2fsck, -D, which will optimize or compress all
4027 of the directories in the filesystem.
4029 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4030 properly clean up and only exit at safe points. Fsck will pass
4031 SIGINT/SIGTERM to its child processes, and wait until they have all
4032 exited before it exits.
4034 The uuid parsing code in the uuid library now properly complains when
4035 an illegally formated uuid is presented to it. (Addresses Debian bug
4038 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4039 and 2.4.17, since the workaround can cause problems when using a 2.4
4040 kernel with an old version of glibc built with the 2.2 headers.
4042 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4043 superblock used by other filesystems. (Addresses Debian bug #147256.)
4045 Added support for the synchronous directory feature written by Andrew
4048 The debugfs program can delete directories using the rmdir command.
4050 Add support for 8k and 16k filesystems (for systems with page sizes
4051 that are greater or equal to 8k or 16k, respectively). Note that
4052 these filesystems can not be mounted on x86 systems, or other systems
4053 with only 4k page sizes, due to limitations in the current Linux VM
4056 Resize2fs requires that the filesystem state be valid and have no
4057 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4058 required that the last fsck time be greater than the last mount time.)
4060 Configure now defaults the man pages directory to /usr/share/man on
4063 E2fsck now offers to truncate inodes which contain too many blocks (so
4064 that i_blocks would overflow. Also fixed handling of large sparse
4067 E2fsck now more completely checks for symlink validity, including
4068 requiring NULL termination and length checks.
4070 E2fsck will offer to try forcing a disk write to remap a bad block
4071 after finding a read error when reading a filesystem metadata block.
4073 Fixed a bug in debugfs which caused the -b and -s options to crash
4074 debugfs, as well as breaking the testb, setb, and clearb functions.
4076 Added a bmap command to debugfs which calculates the logical to
4077 physical block mapping for a particular inode.
4079 Fixed a bug in code which checked to see if a device was mounted which
4080 sometimes (rarely) failed in the case of a plain file.
4082 Fixed a bug in resize2fs where when it reported an error, it would
4083 print a message erroneously indicating that the filesystem had been
4084 resized before it aborted.
4086 When resizing a plain file which is smaller than the requested size,
4087 resize2fs will attempt to extended the file so that programs like
4088 e2fsck will not complain that the file is too small.
4090 Resize2fs will print the actual new size of the filesystem when it is
4093 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4094 information on big-endian systems.
4100 Fixed collisions with C++ reserved words.
4102 Added portability fixes for building e2fsprogs on the HURD and AIX.
4104 Added the ext2ed program for creation of test cases. (ext2ed has many
4105 limitations and bugs which make it unsuitable for production use.)
4107 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4108 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4109 name_len field is byte swampped on big-endian machines, since in the
4110 V2 structure, name_len is a char field which is doesn't need to be
4111 byte swapped --- except if an old-style kernel had byte-swapped the
4112 name_len field as part of the V1 structure.
4115 E2fsprogs 1.27 (March 8, 2002)
4116 ==============================
4118 The warning messages for mke2fs now go to standard error.
4120 Fixed to make sure "make check" runs all of the test programs with
4121 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4123 The mke2fs program checks the boot sector for the BSD disk label, and
4124 avoids erasing it if it is there.
4126 Fixed a bug in e2fsck which caused it to core dump if the journal
4127 inode was missing when it was supposed to be there.
4129 E2fsck now prints ranges in pass 5 when printing deltas for the block
4132 Debugfs's "ls -l" command now will print out the file type information
4133 in the directory entry.
4135 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4136 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4138 Debugfs can now examine the experimental directory indexing
4141 Fixed bug in debugfs which caused it to core dump if modify_inode is
4142 called without an open filesystem.
4144 The debugfs lsdel command now runs its output through a pager first.
4146 When installing manual pages, remove the compressed manual pages first.
4148 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4150 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4151 actually broke things on mips32, sparc32, and Alpha platforms.
4153 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4154 (which is required by the newer libintl libraries).
4159 Fixed various gcc -Wall complaints.
4161 Fixed a few memory leaks in the e2fsck journaling code, and in the
4162 ismounted code checking for a swap device.
4164 Add new inode I/O abstraction interface which exports an inode as
4167 Exported ext2_file_flush as a public interface.
4169 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
4171 Lots of small random portability fixes to make e2fsprogs build under
4172 AIX --- even without the 5L compatibility toolkit, and even using the
4173 uber-crippled AIX native C compiler.
4176 E2fsprogs 1.26 (February 3, 2002)
4177 =================================
4179 Dumpe2fs will keep going now if the bad block inode can't be read.
4180 (Previously it stopped with a fatal error.)
4182 E2fsck will now give an opportunity to run the journal even if the
4183 recovery flag is not set. This is the default behaviour if e2fsck is
4184 using a backup superblock, since the needs_recovery flag will never be
4185 set in the backup superblock copies.
4187 E2fsck now automatically finds the backup superblock/group descriptors
4188 even when the primary superblock is completely destroyed for 2k and 4k
4189 filesystems. (Previously it just guessed/assumed that we were dealing
4190 with a 1k filesystem in that case, and users had to manually specify
4191 the backup superblock number.)
4193 Fixed a bug in e2fsck where it dereferences a null pointer when there
4194 is a problem opening a filesystem in preen mode.
4196 E2fsck now handles external journals correctly; previously it trashed
4197 the external journal device if the journal needed to be replayed.
4199 Work around ulimit incompatibility problem caused by recent 2.4
4200 kernels; the unix IO module will automatically try to set any resource
4201 limits to be infinite on startup.
4203 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
4204 bitmap if it wasn't present and the blocksize was 2k or 4k.
4205 (Addresses Debian Bug #116975)
4207 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
4208 clearing the new V2 fields if they do not make sense or if the ext3
4209 superblock is version 1 superblock.
4211 E2fsck will automatically relocate the ext3 journal from a visible
4212 file (i.e., /.journal) to an hidden inode if the filesystem has been
4213 opened read/write. This allows the users to add a journal while the
4214 filesystem is mounted, but the next time the system is rebooted, the
4215 journal file will disappear. This avoids problems with backups,
4216 stupid operators with superuser bits, etc.
4218 Fix a bug in fsck where it would not support a filesystem type of
4219 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
4221 Fsck now supports fstab entries of the form "ext3,ext2". It will also
4222 automatically identify reiserfs filesystems.
4224 The number of processes spawned by fsck can now be limited using the
4225 FSCK_MAX_INST environment variable.
4227 Fsck now searchs the LVM proc hierarchy to find logical volumes which
4228 should be searched for UUID and label information.
4230 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
4231 limit if at all possible, when opening a block device. (The filesize
4232 limit shouldn't be applied against writes to a block device.)
4234 In mke2fs and e2fsck, specifying the -c option twice will now do
4235 a read/write test on the disk. Update the man pages to encourage
4236 using the -c option, and to discouraging running badblocks separately,
4237 since users tend to forget to set the blocksize when running
4240 Mke2fs now automatically clears the immutable attribute on a
4241 pre-existing .journal file left over from a previous failed attempt to
4242 add a journal to an alreadyy-mounted filesystem.
4244 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
4247 Mke2fs now creates the lost+found directory with permissions of 0700,
4248 so that files that had previously lived in protected directory are
4249 safe if they get dropped in lost+found and the system administrator
4250 doesn't deal with immediately. (Addresses Debian #bug 118443)
4252 Mke2fs and e2fsck (and all programs that use the
4253 ext2fs_check_if_mounted function) will now properly identify that a
4254 device is mounted, even in cases where devfs has confused things with
4255 multiple devices names with the same identity, or if a dim-witted
4256 system administrator has done something stupid like creating device
4257 file aliases in their home directory. Also now checks for swap devices
4258 by using /proc/swaps. (Addresses Debian bug #106622)
4260 Added a new option (-T) to tune2fs which sets the time a filesystem
4263 Speed up e2image when creating sparse raw image files by optimizing
4264 away excess lseek() system calls.
4266 Fix support of large (> 2GB) files when used as a filesystem in
4267 mke2fs, tune2fs, debugfs, and findsuper.
4269 Debugfs's stat and icheck commands now properly deals with large (>
4272 Debugfs's set_super_value command now prints out the list of valid
4273 superblock fields which can be set using the command.
4275 Debugfs's rm and kill_file command now updates the superblock free block
4276 and inode counts, thus keeping the filesystem consistent.
4278 Debugfs's lsdel command now takes an optional argument which allows
4279 the user to only see the most recently deleted files.
4281 A new command (undel) was added to debugfs which automates
4282 undeleting a deleted inode and linking it back to a directory.
4284 Debugfs's ls command now takes a new option, -d, which lists
4285 deleted directory entries.
4287 Debugfs's testb, freeb, setb, and find_free_block commands now take an
4288 optional count argument.
4290 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
4291 be used to signal that a particular inode should not be eligible for
4292 tail-merging --- this is needed for programs like LILO.
4294 The findsuper (an unreleased, uninstalled utility program) has been
4295 improved to add extra validity checks and to add a progress meter.
4296 (It is still an unsupported program; the officially supported way to
4297 recover from a trashed partition table is to use gpart; findsuper is
4298 for wizards only. :-)
4300 Debugfs was fixed to compile with "configure --disable-swapfs".
4302 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
4304 Added new translation file for Turkish.
4309 Fix general gcc -Wall complaints.
4311 E2fsprogs (mostly) works with the dietlibc.
4313 The programming texinfo file has been expanded to include description
4314 of additional libext2fs functions. (Still not compeltely done, but a
4315 lot of the more important functions have been documented.)
4317 Added a umask structure to struct_ext2_filsys, which currently only
4318 modifies the behaviour of ext2fs_mkdir(), but if we add any file
4319 creation functions to libext2fs, we should also make sure they respect
4322 The build-rpm script was fixed to be a bit more safe.
4324 The tests' Makefile now has a way of automating test case creation
4325 for e2fsck, using "make testnew".
4327 Created a new function, ext2fs_dir_iterate2 which passes more
4328 information to the callback function (identical to the one used by
4329 ext2fs_dblist_dir_iterate). The directory iterator functions take a
4330 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
4331 directory entries. If the directory entry is deleted, the callback
4332 function will be called with the entry paraemter set to
4333 DIRENT_DELETED_FILE.
4335 Added new functions, ext2fs_inode_alloc_stats and
4336 ext2fs_block_alloc_stats, which takes updates block/inode allocation
4337 statistics in the bitmaps, block group descriptors, and superblock
4338 when inodes or blocks are allocated or deallocated.
4341 E2fsprogs 1.25 (September 20, 2001)
4342 ===================================
4344 This is primarily a bug-fix release; no new features were added, but
4345 there are a number of embarassing bug fixes and cleanups applied.
4347 Fix a bug mke2fs which causes stack garbage to be written to disk when
4348 zapping disk sectors. (This bug could cause mke2fs to core dump for
4349 some kernels, I suspect with security enhancement patches.)
4351 Remove unneeded #include of <linux/config.h> which was breaking
4352 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
4354 Updated tune2fs man page to reflect the fact that adding or removing a
4355 journal doesn't require running e2fsck.
4357 Remove use of AC_REQUIRE from autoconf which had been used to prevent
4358 AC_CANONICAL_HOST from being called twice; unfortunately this causes
4359 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
4360 used outside of autoconf macros. Fortunately, it doesn't seem to be
4361 necessary any more, anyway.
4363 E2fsck will now not fall back to an alternate superblock if the user
4364 specifies the superblock location explicitly on the command-line.
4365 This allows easier recovery from a situation where the primary
4366 superblock and block groups are slightly corrupted, but the backup
4367 superblocks are completely broken.
4369 Fix problem which caused compile_et and mk_cmds to blow up if
4370 e2fsprogs was in a directory with a pathname that contained spaces.
4372 We are now more paranoid about checking the entry in /etc/mtab to make
4373 sure the filesystem is really mounted, since some broken distributions
4374 (read: Slackware) don't initialize /etc/mtab before checking non-root
4375 filesystems. (Slackware also doesn't check the root filesystem
4376 separately, and reboot if the root filesystem had changes applied to
4377 it, which is dangerous and broken, but there's nothing I can do about
4380 Make UUID library C++ friendly by adding appropriate extern "C"
4381 declarations and using const in the function declarations.
4383 Fix up the com_err texinfo file so that it can product a valid info
4384 file (previously, it could only be used to generate paper
4385 documentation using texinfo.tex).
4388 E2fsprogs 1.24a (September 2, 2001)
4389 ===================================
4391 Fix brown-paper bug in mke2fs which caused it to segfault when
4392 printing the version string.
4395 E2fsprogs 1.24 (August 30, 2001)
4396 ================================
4398 Revert the BLKGETSIZE64 support, since for some distributions, this
4399 ioctl has been used by an unofficial kernel patch to update the last
4400 sector on the disk, and this was causing disk corruption problems as a
4403 Mke2fs is now more careful about zapping swap space signatures and
4404 other filesystem/raid superblock magic values so that programs like
4405 mount who try to use hueristics to determine the filesystem type of a
4406 partition are less likely to be confused.
4408 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
4409 regular file (since Andreas Dilger's on-line resizing tools will set
4412 Fixed some minor texinfo, man pages nits for spelling errors,
4413 texinfo warnings, etc. (Addresses Debian bug #110621.)
4415 E2fsprogs program no longer print the filesystem version number
4416 (i.e. 0.5b), since it only confuses people and doesn't serve any real
4419 E2fsck will once again compile under libc5, since it will supply its
4420 own version of strnlen if necesssary.
4422 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
4423 when specifying the external journal device. tune2fs will also search
4424 devices looking for the externla journal debice when removing.
4426 E2fsprogs 1.23 (August 15, 2001)
4427 ================================
4429 Add initial support for extended attributes (EA); e2fsck will
4430 correctly handle a filesystem with EA's and check the EA blocks for
4433 E2fsck's symlink sanity checking has been cleaned up. It now checks
4434 the i_size value of fast symlinks, and checks for immutable flags
4435 being set of symlinks, etc.
4437 E2fsck now offers to clear inodes which are special files that have a
4438 non-zero i_blocks or i_size field. (The i_size field check was in the
4439 previous version of the code, but due to a bug it didn't offer to
4440 clear the inode unless i_size and i_size_high were both non-zero.)
4442 E2image can now create "raw" image files, which only contain the
4443 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
4444 debugfs, etc., can be run directly on the raw image file.
4446 Add support for the 64-bit block device patches.
4448 Fixed bugs in creating external journals with a 1k blocksize.
4450 Add initial support for external journals (so long as the external
4451 journal only supports a single filesystem) in e2fsck.
4453 Remove requirement for needing to run fsck on a filesystem after
4454 removing a journal (either internal or external).
4456 The man pages now document how to create and manage external journals.
4458 Speed up the check of an ext3 filesystems by avoiding a needless flush
4459 of all of the superblock and block group descriptors.
4461 Speed up creating an internal journal using tune2fs in the case where
4462 the filesystem has a lot blocks already allocated.
4464 Tune2fs has been fixed to make sure that only error messages go to
4465 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
4467 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
4468 now not set the sparse_super feature. (Addresses Debian bug #108165)
4470 Add support in fsck for the filesystem type "auto".
4472 Fsck -A will not try to interpret device names for filesystems which
4473 have a pass number is 0. (Addresses Debian bug #106696).
4475 Fsck prints a warning message if now valid filesystems are passed to
4476 it. (Addresses Debian Bug #107458.)
4478 E2fsck now gives an explicit warning if there filesystem still has
4479 errors at the end of the run. (Addresses Debian bug #104502)
4481 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
4482 reflects an error. E2fsck will also not run the orphan list if the
4483 filesystem contains errors, since the orphan list might be corrupted.
4485 E2fsck now prints the number of large files when given the -v option.
4487 Fixed minor memory leaks in e2fsck.
4489 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
4492 E2fsprogs 1.22 (June 22, 2001)
4493 ==============================
4495 Fixed a bug in e2fsck's handling of orphan inodes which are special
4496 files (i.e., block/character device files, named FIFO's, etc.).
4498 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
4499 tune2fs to fail at adding a journal to a mounted filesystem.
4501 Fixed a few big-endian bugs in e2fsprogs
4502 * The directory block functions were accidentally reporting
4503 some directories as corrupted when they weren't.
4504 * If e2fsprogs is compiled --disable-swapfs, the C language
4505 equivalents weren't being included for big-endian platforms.
4506 (Fixes Debian bug #101686).
4508 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
4513 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
4514 ioctls, and allow them to be defined for non-i386 platforms.
4516 The uuid.h header file is now protected against multiple inclusions.
4518 E2fsprogs is now being developed using BitKeeper. Changed the test
4519 scripts to deal with BK's stripping CR characgters from text files,
4520 and changed the top-level Makefile.in to avoid including BitKeeper
4521 files when generating the source tarball.
4524 E2fsprogs 1.21 (June 15, 2001)
4525 ==============================
4527 Added new configure flags which allow a subset e2fsprogs to be built;
4528 this is most useful for boot floopies, since the resulting shared
4529 libraries and programs are slimmed down by removing features that
4530 aren't necessary for a boot floppy. The new flags that were added
4531 are: --disable-swapfs, which removes support for byte swapping old
4532 legacy PPC/68k filesystems, --disable-debugfs, which removes support
4533 for debugfs from the libext2fs library, --disable-imager, which
4534 removes support for the e2image program, and --disable-resizer, which
4535 removes support for resize2fs.
4537 E2fsck now prints the number of mounts or days elapsed since the last
4538 check when e2fsck is forced to check an otherwise clean filesystem.
4540 Tune2fs now prints an informative message about how often a filesystem
4541 will be checked when adding a journal to the filesystem, to remind the
4542 user that he/she may want to adjust those parameters using tune2fs
4545 Worked around hurd brain-damage which causes e2fsck to sometimes
4546 believe a filesystem is the root filesystem based on device numbers
4547 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
4550 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
4551 erroneous error with the -F option was specified.
4553 Fixed a ext3 recovery bug in the revoke handling; synchronized with
4556 Fixed two bugs in e2fsck's handling of dup block handling, dealing
4557 with relatively uncommon edge cases: a directory with an indirect
4558 block which is claimed by another file, and when the last inode in the
4559 filesystem has blocks claimed by another file.
4561 E2fsck now checks to see if the i_size field of a fast symlink is too
4562 big, and offers to clear the symlink if so.
4564 E2fsck now checks to see if i_size_high of special files is non-zero,
4565 and offers to clear i_size_high.
4567 Fix e2fsck's handling of incompatible journal flags so that the user
4568 has chance to abort, and then has the option to clear out the journal
4569 entirely. (Addresses Debian bug #98527.)
4571 Fixed a bug in fsck which could cause it to core dump if a mix of
4572 standard and non-standard device names are used in /etc/fstab.
4573 (Debian bug #100559)
4575 Fixed a bug in debugfs which caused read errors when copying a file to
4578 The debugfs set_super_value command can now modify the s_lastcheck field.
4580 Fixed a bug in lsattr and chattr which was accidentally introduced in
4581 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
4582 directories correctly because the change modified the layout of struct
4583 dirent to be incompatible with the libe2p shared library.
4585 Cleaned up the mke2fs manual page and included a discussion about why
4586 it's good to periodically check the filesystem even when journaling is
4592 Fix general gcc -Wall complaints.
4594 The types needed by the ext2 header files are now provided by
4595 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
4597 Integers are now preferred to longs when trying to find a 32-bit type
4598 in ext2_types.h. Also, if linux/types.h has already been defined,
4599 don't try to redefine the types.
4601 Fixed make depend script so that it automatically corrects the
4602 pathname cleanups performed by make -M, so I don't have to fix them up
4605 Fixed the d_loaddump test case to be more robust, and not depend on
4608 Removed debugfs's dependence on pread(), which was accidentally
4609 intrudced in e2fsprogs 1.20
4611 Fixed a performance bug in the libext2fs's icount routine; the size
4612 estimate of the icount array was incorrectly being calculated.
4614 Removed use of the badblocks compatibility functions in the e2fsprogs
4617 Added paranoia code which protects against strange cases where /etc
4618 isn't on the root filesystem, or if /etc/mtab doesn't exist.
4620 The header file ext2_types.h is now installed.
4622 Autoconf is used to determine when we are on big-endian machines,
4623 instead of doing run-time tests, to save a few bytes of code.
4625 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
4626 functions are no longer inline functions, which saves space and
4627 doesn't really cost any real performance.
4629 The ext2fs library no longer depends on the e2p library. (What need
4630 there was of it --- namely, fsetflags, was coded in-line).
4632 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
4633 when the user is stupid and tries compiling the package using "make
4636 Miscellaneous code cleanups:
4637 * Added missing files from Makefile.in's SRCS file, so that
4638 their dependencies would be properly calculated.
4639 * Removed redundant code
4640 * Fixed comments in code
4641 * Removed no-longer unneeded argsused #pragma.
4644 E2fsprogs 1.20 (May 20, 2001)
4645 =============================
4647 Add support for replaying the ext3 journal purely in user mode,
4648 including handling the orphaned inode list. Used code contributed by
4649 Andreas Dilger, with bug fixes and the orphaned inode handling done
4652 The mke2fs and tune2fs programs can create or modify a filesystem to
4653 include an ext3 journal. Tune2fs also can be used to remove an ext3
4654 journal from a filesystem.
4656 E2fsck will now check for the existence of a linked list of orphan
4657 inodes in the superblock, and clear those inodes before starting the
4658 rest of the filesystem check (but after the journal playback).
4660 E2fsck now validates the file descriptor passed to the -C option,
4661 which saves against the completion bar getting written to an
4662 unexpected location, such as the disk being checked. (Debian
4663 bug/wishlist #55220)
4665 E2fsck will now bump the filesystem revision number from zero to one
4666 if any of the compatibility bits are set.
4668 Fixed a bug where a badly corrupted directory on a big endian system
4669 could cause e2fsck to die with a bus error. The
4670 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
4671 the ext2 library now does alignment sanity checks on the rec_len field
4672 of the directory entry before using it.
4674 The ext2 library has been enhanced to make tune2fs safe to run on
4675 mounted filesystems. (Users could usually get away with using tune2fs
4676 on mounted filesystems before, but with the advent of ext3 and
4677 journaling, it became important to make tune2fs was *really* safe for
4678 use even when the filesystem being modified is mounted.) E2label is
4679 now implemented by tune2fs using an argv[0] dispatch, so that e2label
4680 is also now safe for use on mounted filesystems.
4682 Added a new program, e2image, which creates a backup of critical ext2
4683 filesystem data structures. The generated image file can be examined
4684 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
4685 the image file to help recover very badly damaged filesystems.
4687 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
4688 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
4689 large file when deciding whether or not the filesystem has large files.
4691 Fixed lsattr and chattr so that they work correctly on large files.
4692 (Fixes Debian bug #72690.)
4694 Removed limitation in get_device_size() which imposed a one terrabyte
4695 filesystem limitation. (Most 2.2 kernels still have a signed int
4696 problem which cause 1 TB block device limitation. Fortunately, the
4697 kernel patches to fix this are much easier than fixing the 2TB
4698 limitation in the kernel. :-)
4700 A max_mount_count of zero is now treated as if no mount count were
4701 set. (Previously, no mount count was indicated by using -1, and a
4702 mount count of zero caused e2fsck to always be run.)
4704 Mke2fs supports two new filesystem types largefile and largefile4.
4706 Mke2fs now adds some randomness in s_max_mount_count so that multiple
4707 filesystems won't be all checked at the same time under normal
4710 Fixed bug in the progress bar printing code which could cause e2fsck
4711 to core dump on an illegal filesystem.
4713 Fixed bug in fsck which could allow more than one instance of e2fsck
4714 to be printing a progress bar. (Debian bug #65267)
4716 Fsck using a UUID or a LABEL specifier will work even if devfs is
4717 compiled into the kernel and not mounted. If the pathnames in
4718 /proc/partitions are incorrect, fsck will search /dev for the correct
4719 device (using the new ext2fs_find_block_device library function).
4720 Fsck now also checks the RAID devices first so that they are properly
4721 found when they are in use. Support has also been added to support
4722 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
4724 Fixed a bug in fsck which caused it not deal properly with 16
4725 byte long filesystem labels.
4727 Fsck's -t option has been made a lot more flexible. The semantics for
4728 what happens if a comma-separated list to fsck has been regularized,
4729 and it is now possible to filter what filesystems will get checked
4730 based what is in the filesystem's fstab entry's option field. (Debian
4733 The dumpe2fs program can now print out the group description
4734 information in hex, and also prints the location of the superblock and
4735 block group descriptor for those block groups that have them.
4737 Mke2fs now clears the ext2 superblock before it starts creating a
4738 filesystem, so that the superblock magic number is only written if the
4739 filesystem creation process successfully completes.
4741 The debugfs program's stat command now pretty-prints the blocks used
4742 by an inode so that it's more compact and informative.
4744 The debugfs stats command now uses the same libe2p code (which is used
4745 by dumpe2fs) to print the superblock header information. This is more
4746 complete, and it avoids a bit of code duplication.
4748 Added a new debugfs command, set_super_value (ssv) which allows the
4749 user to set arbitrary superblock fields.
4751 Debugfs was extended to support inode numbers in hex (by prefixing
4752 them with 0x), and so that modify_inode can set the inode generation
4753 number. Also, there is now a new function command called logdump
4754 which will dump an ext3 journal.
4756 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
4759 Debugfs's dump command now stops immediately upon reporting a disk
4760 read error. (Fixed a bug in ext2fs_file_read library routine which
4761 caused debugfs not to stop.) (Debian bug #79163)
4763 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
4764 checked before /etc/mtab is used, since /proc/mounts is more likely to
4767 Added portability fixes for Solaris and Linux/ia64.
4769 Various manual pages were clarified and cleaned up. (Fixed debian
4770 bugs #63442, #67446, and #87216)
4776 The e2fsck message printer now supports %Iu and %Ig, which will print
4777 out the inode's user and group owners, respectively.
4779 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
4780 that no longer dependent on the system having the correct version of
4781 the kernel header files.
4783 Added a new function to libext2, ext2fs_find_block_device(), which
4784 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
4785 device given its device number.
4787 Added a new function to libext2, ext2fs_sync_device, which centralizes
4788 all of the places which might try to use the BLKFLSBUF or FDFLUSH
4789 ioctls (and usually failing to define them since the system header
4790 files don't usually do this for us, and we're trying to avoid usage of
4791 kernel include files now).
4793 Added new utility programs in tests/progs: random_exercise and
4794 hold_inode. They aren't built by default; they're useful for
4795 exercising ext3 filesystem code.
4797 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
4798 the filesystem close functions to only update the superblock, and to
4799 not touch the block group descriptors. Needed by tune2fs when
4800 modifying a mounted filesystem.
4802 Got rid of struct ext2fs_sb and replaced it with the standard struct
4803 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
4804 source (but not binary) compatibility of some users of the ext2
4805 library. Those applications should just simply do a global search and
4806 replace of struct ext2fs_sb with struct ext2_super_block, and include
4807 the new header file <ext2fs/ext2_fs.h> which defines it.
4809 The ino_t type has been renamed ext2_ino_t to protect applications
4810 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
4811 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
4812 unexpected ABI change.
4814 The Makefiles have been reworked so that "make check" can be run from
4815 the top-level Makefile.
4817 Fix general gcc -Wall complaints and removed dead code.
4819 Remove use of NOARGS, because we assume everyone does ANSI C these
4822 Added build-rpm script from sct.
4824 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
4827 New function ext2fs_flush_icache which must be called if the
4828 application program modifies the inode table blocks without going
4829 through ext2fs_write_inode() interface.
4831 New ext2fs_check_mount_point() function, which will return the mount
4832 point of a device if mounted.
4834 The io_channel abstraction now has an optional interface,
4835 io_channel_write_range, which allows specific byte ranges to be
4838 The unix_io IO channel now supports write-through caching, so that
4839 journal creation is more efficient.
4841 Added x86 assembly language routines to support byte swapping, to
4842 reduce executable size.
4844 Fixed bug in the utility program subst so that it's possible to
4845 replace a substitution variable with a zero-length string.
4847 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
4848 slipped into some of the problem number.
4850 E2fsprogs 1.19 (July 13, 2000)
4851 ==============================
4853 Release the resize2fs program since the timeout before it could
4854 be released under the GPL has finally expired.
4856 Add experimental support needed for the ext2 compression patches.
4857 This requires compiling e2fsprogs with the --enable-compression flag
4858 to the configure script.
4860 Added ext3 journalling support. E2fsck will run the journal (if
4861 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
4862 installed as a symlink to e2fsck. Fsck has been taught about ext3,
4863 and treats it the same as ext2 in terms of the progress bar logic.
4864 Dumpe2fs will display the superblock journaling information if the
4865 filesystem has a journal. The ext2 library will now permit opening an
4866 ext3 filesystem with the recovery flag set. This is necessary for
4867 on-line dump's to work correctly, but there may be issues with this
4868 working well since ext3 is much less agressive about syncing blocks to
4869 the filesystem, since they're safe on the journal.
4871 Tune2fs and e2fsck have been changed to allow the mount_count check to
4872 be disabled by setting max_mount_count to -1. (This was already
4873 supported by the kernel.)
4875 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
4876 are used for ext3 as well.
4878 Added internationalization support for e2fsprogs; must be enabled
4879 by passing --enable-nls to configure.
4881 Always use the provided ext2fs header files to insulate ourselves from
4882 kernel version changes. Which include files are used by e2fsprogs
4883 have also been cleaned up to improve portability.
4885 Limit the number of times that e2fsck updates the progress bar so that
4886 people who are booting using a 9600 baud console don't get swampped by
4889 Improved the loop detection algorithm in e2sck's pass #3 so that it is
4890 much, much faster for large filesystems with a large number of
4893 The memory footprint for e2fsck is now slightly smaller than before.
4895 E2fsck now checks if special devices have a non-zero size, and offers
4896 to clear the size field if it finds such an inode.
4898 E2fsck now checks if special devices have the append-only flag set,
4899 and offers to clear the inode.
4901 E2fsck now properly handles some "should never fail" cases during a
4902 bitmap copy in pass5.
4904 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
4906 E2fsck now calculates the correct location of the backup superblock in
4907 the case of filesystem blocksizes > 1k.
4909 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
4910 which normally didn't cause problems under most filesystem parameters,
4911 but could cause a valid superblock to be rejected in extreme cases.
4912 Other checks for validating superblock values were made more
4915 Added non-destructive write testing to the badblocks program, courtesy
4916 of David Beattie. The badblocks also now has an option to input the
4917 current set of bad blocks, so that known bad blocks are skipped to
4918 speed up the badblocks test. There is also a persistent rescan
4919 feature which causes badblocks to run until it has completed some
4920 number of passes without discovering any new bad blocks.
4922 Badblocks now checks to see if the device is mounted and refuses to do
4923 the tests involving writing to the device if it is mounted. Also,
4924 badblocks now allows the number of blocks to be checked to be
4925 defaulted to the size of the partition.
4927 Fixed a bug in fsck which didn't allow non-root users to be able to
4928 check filesystems if there were any LABEL= or UUID= entries in
4931 The Hurd doesn't support the filetype filesystem feature. The mke2fs
4932 program now makes sure that for the Hurd, the filestype feature is
4933 turned off. E2fsck will check to see if the filetype feature is
4934 turned on for Hurd filesystems, and offer to turn off the feature.
4936 Mke2fs now has a safety check to make sure the number of blocks do not
4937 exceed 32 bits even on a 64 bit platform.
4939 Really fixed a bug in fsck to allow "fsck -As" to run interactive
4940 fsck's. (For those people who like to do interactive fsck's in the
4943 Debugfs has a few new features: the rdump command, which will do a
4944 recursive dump of a directory and all of its contents, and the lcd
4945 command which does a local chdir (much like the ftp command of the
4946 same name). In addition, the debugfs program and the open_filesystem
4947 command now takes three new options: -b and -s, which allows the
4948 blocksize and superblock location to be specified, and the -c option
4949 which is used in catastrophic situations where the block group
4950 descriptors are corrupt. If the -c option is specified, debugfs will
4951 skip trying to read in the block and inode bitmaps.
4953 Debufs's lsdel command was fixed to handle bad blocks in the inode
4956 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
4959 General improvements in error messages
4961 - Mke2fs prints a sane error message if the partition size is zero
4962 (usually because the partition table wasn't reread by the
4963 kernel due to the partition being busy), instead of "invalid
4964 argument passed to ext2 library while initializing superblock".
4966 - Fsck now prints more self-explanatory message if an invalid UUID=
4967 or LABEL= specification is passed to it.
4969 UUID library changed to use the LGPL.
4971 Fixed a bug in the UUID library where very rapid calls to the
4972 time-based UUID generator could cause duplicate UUID's to be returned.
4973 This was not a problem for e2fsprogs, but it could be a problem for
4974 other users of the library.
4976 Make the UUID library more robust in the face of missing or an
4977 improper /dev/urandom or /dev/random files.
4979 Added some random portability fixes for Solaris.
4981 Some minor man page updates.
4983 Fixed a memory leak in the ss library.
4989 We now try to use lseek64 and open64 from the LFS if possible.
4991 The 3rd parameter in e2p's print_flags is now a flags word, instead of
4994 The mark and unmark bitmap functions now return the previous state of
4995 the bit that was being changed, which is useful for some speed
4998 The following functions have been added to enhance the badblocks list
4999 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5000 ext2fs_badblocks_equal.
5002 The ext2 header files now have the latest journalling fields to the
5005 The ext2fs_mkdir function in libext2fs now properly backs out of error
5006 conditions robustly.
5008 Cleaned up makefiles:
5009 - to cleanly compile with the -j flag.
5010 - so distclean removes all generated files.
5011 - so in case of an error while installing header files, the make aborts.
5013 Fix test_script so that it works correctly when compiling in the
5016 The random UUID generation routine has been made slightly better in
5017 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5018 is still not recommended if /dev/random doesn't exist, however; it's
5019 better to use the time/ethernet MAC address UUID in this case.)
5021 Clean up the build process so it's more friendly in case of missing
5024 The ext2fs header file can now be #include'd into C++ programs.
5026 The e2p.h header file is now installed.
5028 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5032 E2fsprogs 1.18 (November 10, 1999)
5033 ==================================
5035 Fix a core dumping bug in e2fsck if an imagic inode is present or
5036 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5037 has to restart pass 1 processing. E2fsck now closes the filesystem
5038 before freeing a large number of its data structures, so in the case
5039 of future memory faults, at least the fixed filesystem will be fully
5042 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5043 imagic inode, it will offer to clear the imagic flag.
5045 E2fsck will now offer to clear the immutable flag on special files
5046 (device/socket/fifos) when running it in non-preen mode.
5048 E2fsck will now set the filetype when creating /lost+found, and when
5049 connected orphaned inodes to /lost+found.
5051 Debugfs's ncheck and icheck commands now handles the case where there
5052 are bad blocks in the inode table without bombing out.
5054 The badblocks list processing code has been made more efficiently for
5055 appending a large number of (ordered) badblocks to the badblocks list.
5057 Some minor man page updates.
5059 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5060 mode, but some people like to do this in boot scripts for silly reasons).
5065 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5066 with the problem code convention.
5068 The badblocks list regression test program has been updated to work
5069 with previously made API name changes.
5071 The ext2fs_free() command now uses the new badblocks API to avoid
5072 using the compatibility layer.
5074 Added new regression test cases; the run_e2fsck test script now
5075 supports the ability for a test case to run a prepratory command
5076 before running e2fsck.
5078 E2fsprogs 1.17 (October 26, 1999)
5079 =================================
5081 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5084 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5085 thus potentially causing problems if a binary UUID contained a NULL
5088 E2fsck now uses stricter checks for directory entries in pass 2:
5089 zero-length filenames are not allowed; neither are 8 byte long
5092 The debugfs "dirty" command now clears the filesystem valid bit.
5093 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5094 bit in the in-core superblock image. The new functionality is more
5095 what the user expects, and is more useful.)
5097 Added a debugging hook to test parallel fsck; if the environment
5098 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5099 will be checked in parallel when they normally would not be.
5104 Fixed some #ifdef's for compilation under the Hurd OS.
5106 Fixed minor W2K compatibility problems.
5108 Fixed some miscellaneous GCC warnings.
5111 E2fsprogs 1.16 (October 22, 1999)
5112 =================================
5114 Fixed a race condition bug in fsck; when printing a progress bar, if
5115 checking multiple filesystems in parallel, it was possible for fsck to
5116 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5117 handler, which would cause it to terminate with a signal 10.
5119 E2fsck now properly handles filesystems that have the
5120 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5121 filesystem into using or not using FILETYPE feature.
5123 E2fsck now properly handles filesystems that have the IMAGIC feature
5124 turned on (this is used on Linux AFS servers).
5126 The mke2fs program now creates filesystems that have the filetype and
5127 sparse_superblock features enabled by default, unless it is run on a
5128 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5129 so there is now a new flag -O which allows the user to specify with
5130 which features she would like to create the filesystem; "mke2fs -O
5131 none" will create a filesystsem compatible with 2.0 kernels.
5133 The tune2fs program now has a -O option which allows the user to set
5134 and reset "safe" filesystem features. Currently, the only ones which
5135 allows to be modified are the filetype and sparse_superblock features.
5136 Note setting or clearing either feature will require running e2fsck on
5137 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5138 requires that there is enough free space on the filesystem for the
5139 extra superblocks which will be created by e2fsck.)
5141 Debugfs can now set and print filesystem features in the superblock
5142 using the "features" command. Dumpe2fs will print out the complete
5143 set of features when listing the superblock.
5145 Dumpe2fs has new options -f (force) and -h (header-only).
5147 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5148 message to come up. This could happen when decrementing or
5149 incrementing a link count could result in an overflow.
5151 Fixed a bug in e2fsck where the block count on the lost+found
5152 directory would not be properly incremented when the directory was
5153 expanded to the point where an indirect block needed to be allocated.
5155 E2fsck now makes some additional sanity checks on the superblock to
5156 avoid crashing or giving a memory allocation error if some of the
5157 values in the superblock are unresonable (but the superblock otherwise
5160 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5161 require two passes to completely fix the filesystem. This happened if
5162 an inode claimed blocks that was part of the filesystem metadata
5163 (typically, when garbage was written into an inode table or indirect
5164 block, since this kind of filesystem corruption normally doesn't
5167 On the Alpha, glibc declares st_flags although it isn't actually used;
5168 the configure script was improved to detect this case so that
5169 e2fsprogs can avoid using the non-functional stat field.
5171 The manual pages were updated to use a more consistent formatting
5172 style consistent with standard Unix man pages. Mke2fs's man page
5173 added documentation for a few previously undocumented options.
5175 Fixed minor display bugs in tune2fs and mke2fs.
5180 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
5182 Added features to parse and print feature strings into the e2p library.
5183 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
5185 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
5186 whose directory entries contain proper filetype information if the
5187 filesystem supports it.
5189 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
5190 the directory entry filetype information. This is used to set the
5191 directory entry filetype information if the filesystem supports it.
5193 Fixed a bug in ext2fs_expand_dir() where the block count in a
5194 directory's inode would not be properly incremented when the directory
5195 was expanded to the point where an indirect block needed to be
5199 E2fsprogs 1.15 (July 18, 1999)
5200 ==============================
5202 Add configuration checks so that e2fsprogs will compile cleanly on
5203 Linux 2.3 kernels that have renamed i_version to i_generation.
5205 E2fsck now prints a progress/completion bar (and not just a simple
5206 spinner) if the -C0 option is requested or if it receives a SIGUSR1
5207 signal. Fsck will automatically manage the (potentially muliple)
5208 e2fsck processes to print completion bars if it is given a -C option,
5209 with the right thing happening if multiple filesystems are being
5210 checked in parallel.
5212 Mke2fs now has better automatic hueristics to determine the filesystem
5213 parameters to be used for a particular filesystem. Added a new option
5214 -T which allows the user to specify how the filesystem is to be used,
5215 which helps mke2fs do a better job selecting the filesystem parameters.
5217 Mke2fs now creates revision 1 filesystems by default, and with the
5218 sparse superblock feature enabled. The sparse superblock feature is
5219 not understood by Linux 2.0 kernels, so they will only allow read-only
5220 mounts of filesystems with this sparse superblocks.
5222 Fix bug where if /dev/null couldn't be opened (should never happen),
5223 e2fsck would hang in a tight loop.
5225 Make e2fsck handle the case where /lost+found isn't a directory.
5227 E2fsck now uses mallinfo if it exists to get accurate statistics about
5230 Fix bug in e2fsck where it wouldn't check to see if a disconnected
5231 inode had any problems before connecting it to /lost+found.
5233 Add check to e2fsck so it makes sure that total number of inodes in
5234 the filesystem is a sane number.
5236 Fix fencepost error when clearing an the end of the block bitmap which
5237 caused the last block in the bitmap not to get cleared.
5239 Cleaned up a number of messages in e2fsck:
5240 * The message "Group's #'s copy of the group descriptor..."
5241 was fixed so that the correct number would be displayed.
5242 * Added missing space in the "disk write-protected" error messsage
5243 * Cleaned up the error message printed when a non-interactive
5244 e2fsck needs to abort a check because the filesystem
5245 appears to be mounted.
5247 Added a new command-line utility, uuidgen, which will create and print
5250 Make debugfs's icheck command more robust by checking to make sure an
5251 inode has valid blocks before interarting over the inode's blocks.
5253 UUID generation now uses a random-based scheme whenever possible to
5254 prevent potential privacy problems.
5256 Man pages for all of the UUID functions in the lirbary were added.
5258 Fixed bug in fsck so it won't coredump if a filesystem not in
5259 /etc/fstab is given to it.
5261 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
5262 that most of the other mount utilities understands.
5264 Mke2fs will make a filesystem even if it appears mounted if the force
5267 Dumpe2fs has new command-line options which allow a filesystem expert
5268 to specify the superblock and blocksize when opening a filesystem.
5269 This is mainly useful when examining the remains of a toasted
5272 The badblocks program has been updated to display correctly on disks
5273 with large block numbers.
5275 The badblocks program no longer gives spurious errors when errors
5276 occur on non-block boundaries, which is common if the blocksize is
5279 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
5280 MKE2FS_SYNC environment variable is set. This is to work around a VM
5281 bug in the 2.0 kernel. I've heard a report that a RAID user was able
5282 to trigger it even using a 2.2 kernel, but hopefully it will not be
5283 needed for most Linux 2.2 users.
5285 Fixed miscellaneous documentation and man pages.
5290 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
5291 in e2fsck's pass1.c really should have been static.
5293 The return value of the uuid_compare() function was changed to make it
5294 match with the convetions used by strcmp, memcmp, and Paul Leach's
5295 UUID sample document.
5297 The "make depend" process has now been made more automated; it now
5298 automatically word-wraps the dependencies, and only replaces source
5299 Makefile.in if there has been a change in the dependencies. Also, a
5300 top-level "make depend" now recurses through all the subdirectories
5303 The Makefile in .../util has been changed so that subst is built using
5304 the native C compiler during a cross-compilation, since the subst
5305 program is only used during the build process. Also add an explicit
5306 rule to build util/subst by cd'ing to the correct directory and
5309 The man directories are defined in terms mandir, so that the configure
5310 script can override the location of the manual pages.
5312 The config files have been updated to recognize new machine types for
5313 both the i386 and alpha families.
5315 Fsck has been modified so that it will accurately create an
5316 fsck_instance even when the noexecute flag is set. This allows for
5317 accurate debugging of the fsck pass structure. Also, when the verbose
5318 flag is given twice, fsck will print debugging information about when
5319 fsck is waiting for jobs to finish.
5322 E2fsprogs 1.14 (January 9, 1999)
5323 ================================
5325 Fix the fstab parsing code so that it can handle blank lines and
5326 comment characters. Also, missing pass numbers need to be treated as
5329 Fixed a bug in e2fsck where under some circumstances (when e2fsck
5330 needs to restart processing after fixing an egregious inconsistency)
5331 it would try to access already freed memory.
5333 E2fsck now prints non-printable characters in directory entries and
5334 pathnames using '^' and 'M-' notation.
5336 Fixed chattr so that it will ignore symbolic links when doing
5337 recursive descent traversals. For both chattr and lsattr, no longer
5338 print the version string unless the -V option is given.
5340 Allow the system administrator to directly specify the number of
5341 inodes desired in the filesystem, for some special cases where this is
5344 Fix portability problems so that e2fsprogs can be compiled under Linux
5345 1.2 systems and Solaris systems.
5347 Update the config.guess file with a more recent version that will
5348 identify newer Linux platforms.
5353 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
5354 an inode number of zero is passed to them.
5356 E2fsprogs 1.13 (December 15, 1998)
5357 ==================================
5359 Fixed a bug in debugfs where an error messages weren't getting printed
5360 when the ext2 library routines to read inodes returned errors in the
5361 stat, cmri and rm commands.
5363 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
5364 provided, it won't create an inode table smaller than the minimum
5365 number of inodes required for a proper ext2 filesystem.
5367 Fsck now parses the /etc/fstab file directly (instead of using
5368 getmntent()), so that it can distinguish between a missing pass number
5369 field and pass number field of zero. This caused problems for
5370 diskless workstations where all of the filesystems in /etc/fstab have
5371 an explicit pass number of zero, and fsck could not distinguish this
5372 from a /etc/fstab file with missing pass numbers.
5374 E2fsck will create a /lost+found directory if there isn't one in the
5375 filesystem, since it's safer to create the lost+found directory before
5378 Fixed e2fsck so that it would detect bogus immutable inodes which
5379 happen to be sockets and FIFO files, and offer to clear them.
5381 If a filesystem has multiple reasons why it needs to be checked, and
5382 one of the reasons is that it is uncleanly mounted, e2fsck will print
5383 that as the reason why the filesystem is being checked.
5385 Cleaned up the output routines of mke2fs so that it doesn't overflow
5386 an 80 column display when formating really big filesystems.
5388 Added a sanity check to e2fsck to make sure that file descriptors 0,
5389 1, 2 are open before opening the hard disk. This avoids a problem
5390 where a broken program might exec e2fsck with those file descriptors
5391 closed, which would cause disastrous results if the kernel returns a
5392 file descriptor for the block device which is also used by FILE *
5395 Fixed up the e2fsck progress reporting functions so that the values
5396 reliably reach 100% at the completion of all of the e2fsck passes.
5398 Fixed minor documentation bugs in man pages and usage messages.
5403 Fixed a number of lint warnings in the ext2fs library and potential
5404 portability problems from other OS's header files that might define
5405 CPP macros for names like "max" and "min".
5407 ext2fs_badblocks_list_add() has been made more efficient when it needs
5408 to grow the bad blocks list.
5410 Fixed a bug in e2fsck which caused it to dereference a freed pointer
5411 just before exiting.
5413 Fixed the substition process for generating the mk_cmds and compile_et
5414 scripts so that they will work outside of the build tree.
5416 Add sanity check to e2fsck so that if an internal routine
5417 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
5418 and causing a core dump. This should never happen, but...
5420 E2fsprogs 1.12 (July 9, 1998)
5421 ==================================
5423 E2fsprogs now works with glibc (at least with the version shipped wtih
5424 RedHat 5.0). The ext2fs_llseek() function should now work even with
5425 i386 ELF shared libraries and if llseek() is not present. We also
5426 explicitly do a configure test to see if (a) llseek is in libc, and
5427 (b) if llseek is declared in the system header files. (See standard
5428 complaints about libc developers don't understand the concept of
5429 compatibility with previous versions of libc.)
5431 The ext2fs library now writes out the block group number in each of
5432 the superblock copies. This makes it easier to automatically
5433 determine the starting block group of the filesystem when the block
5434 group information is trashed.
5436 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
5437 which means that e2fsprogs will ignore the high 8 bits of the
5438 directory entry's name_len field, so that it can be used for other
5441 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
5442 E2fsprogs will now support filesystems with 64-bit sized files.
5444 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
5446 Added new program "e2label", contributed by Andries Brouwer. E2label
5447 provides an easy-to-use interface to modify the filesystem label.
5449 Fixed bug so that lsattr -v works instead of producing a core dump.
5451 Fixed a minor bug in mke2fs so that all groups with bad superblock
5452 backup blocks are printed (not just the first one).
5454 Mke2fs will check the size of the device, and if the user specifies a
5455 filesystem size larger than the apparent size of the device it will
5456 print a warning message and ask if the user wants to proceed.
5458 E2fsck has a new option -C, which sends completion information to the
5459 specified file descriptor. For the most part, this is intended for
5460 programs to use, although -C 0 will print a spinning character to the
5461 stdout device, which may be useful for users who want to see something
5462 happening while e2fsck goes about its business.
5464 Fixed a bug in e2fsck which could cause a core dump when it needs to
5465 expand the /lost+found directory, and sometimes the bitmaps haven't
5466 been merged in. Also fixed a related bug where ext2fs_write_dir_block
5467 was used to write out a non-directory block. (Which would be bad on a
5468 non-Intel platform with byte swapping going on.)
5470 Fixed bug in e2fsck where it would print a "programming error" message
5471 instead of correctly identifying where a bad block was in used when
5472 the bad block was in a non-primary superblock or block group
5473 descriptor. Also fixed a related bug when sparse superblocks are in
5474 use and there is a bad block where a superblock or block group
5475 descriptor would have been in a group that doesn't include a
5478 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
5479 the block group descriptor table is corrupt, it was possible to try to
5480 allocate a huge array, fail, and then abort e2fsck.
5481 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
5482 and subsitutes reasonable values if the descriptors are obviously bogus.
5484 If e2fsck finds a device file which has the immutable flag set and the
5485 i_blocks beyond the normal device number are non-zero, e2fsck will
5486 offer to remove it, since it's probably caused by garbage in the inode
5489 When opening a filesystem, e2fsck specially checks for the EROFS error
5490 code, and prints a specific error message to the user which is more
5493 If the filesystem revision is too high, change the e2fsck to print
5494 that this is either because e2fsck is out of date, or because the
5495 superblock is corrupt.
5497 E2fsck now checks for directories that have duplicate '.' and '..'
5498 entries, and fixes this corruption.
5500 E2fsck no longer forces a sync of the filesystem (with attendant sleep
5501 calls) at all times. The ext2fs_flush() function now performs a sync
5502 only if it needed to write data blocks to disk.
5504 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
5505 certain errors would not be properly reported.
5507 Updated and expanded a few points in the man pages which users
5508 complained wheren't explicit enough.
5510 Added special case byte-swapping code if compiling on the PowerPC, to
5511 accomodate the strange big-endian variant of the ext2 filesystem that
5512 was previously used on the PowerPC port.
5518 Removed C++ keywords from the ext2fs libraries so that it could be
5521 E2fsck's internal organization has now been massively reorganized so
5522 that pass*.c don't have any printf statements. Instead, all problems
5523 are reported through the fix_problem() abstraction interface. E2fsck
5524 has also been revamped so that it can be called as a library from a
5527 Added new fileio primitives in libext2fs for reading and writing
5528 files on an unmounted ext2 filesystem. This interface is now used by
5531 Added a new libext2fs function for mapping logical block numbers of
5532 a file to a physical block number.
5534 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
5535 a block, zeros it, and updates the filesystem accounting records
5538 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
5539 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
5541 The libext2fs functions now use a set of memory allocation wrapper
5542 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
5543 instead of malloc, free, and resize. This makes it easier for us to
5544 be ported to strange environments where malloc, et. al. aren't
5545 necessarily available.
5547 Change the libext2fs fucntion to return ext2-specific error codes
5548 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
5549 and depending on the existence of system error codes (such as EEXIST
5552 Renamed io.h to ext2_io.h to avoid collision with other OS's header
5555 Add protection against ext2_io.h and ext2fs.h being included multiple
5558 The types used for memory lengths, etc. have been made more portable.
5559 In generla, the code has been made 16-bit safe. Added Mark
5560 Habersack's contributed DOS disk i/o routines.
5562 Miscellaneous portability fixes, including not depending on char's
5565 The io_channel structure has a new element, app_data, which is
5566 initialized by the ext2fs routines to contain a copy of the filesystem
5569 ext2fs_check_directory()'s callback function may now return the error
5570 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
5571 really do the checking, despite the presence of the callback function.
5574 E2fsprosg 1.11 (June 17, 1997)
5575 ==============================
5577 Fixed e2fsck to detect (previously ignored) conflicts between the
5578 superblock or block group descriptors and block bitmaps, inode
5579 bitmaps, and inode tables.
5581 Fixed bug in e2fsck so that when the message printed out when a block
5582 or inode bitmap conflicts with other data, it has the correct group
5585 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
5586 to badblocks. This meant that not all of the filesystem was being
5587 tested for bad blocks!
5589 Fixed an array boundary overrun case which cropped up in
5590 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
5593 Adjusted the number of columns printed by mke2fs when displaying the
5594 superblock backups to avoid running over 80 columns when making a
5595 really big filesystem.
5597 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
5598 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
5599 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
5604 Fixed install rule in lib/ss so that ss_err.h is actually getting
5607 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
5608 bassed back to the caller.
5610 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
5611 setting the current inode number (which meant this function wasn't
5614 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
5615 blocks in the bitmap when increasing the size of the bitmap.
5617 Changed the initial number of blocks allocated by ext2fs_init_dblist()
5618 to be more realistic.
5620 Added a new function ext2fs_allocate_group_table, which sets up the
5621 group descriptor information (and allocates inode and block bitmaps,
5622 and inode tables for a particular group). The function was created by
5623 factoring out code form ext2fs_allocate_tables().
5625 Added a new function ext2fs_move_blocks which takes a bitmap of the
5626 blocks to be moved, and moves them to another location on the
5629 Make the unix_io channel's io_channel_flush implementation calls sync()
5630 to to flush the kernel buffers to disk.
5632 Added a new function ext2fs_dblist_count returns the number of
5633 directory blocks in dblist.
5636 E2fsprogs 1.10 (April 24, 1997)
5637 ===============================
5639 Mke2fs once again defaults to creating revision #0 filesystems, since
5640 people were complaining about breaking compatibility with 1.2 kernels.
5641 Warning messages were added to the mke2fs and tune2fs man pages that
5642 the sparse superblock option isn't supported by most kernels yet (1.2
5643 and 2.0 both don't support parse superblocks.)
5645 Added new flag to mke2fs, -R <raid options>, which allows the user to
5646 tell mke2fs about the RAID configuration of the filesystem. Currently
5647 the only supported raid option is "stride" which specifies the width
5650 Fixed bug in e2fsck where pass1b would bomb out if there were any
5651 blocks marked bad in the inode table.
5653 Fixed rare bug in mke2fs where if the user had a very unlucky number
5654 of blocks in a filesystem (probability less than .002) the resulting
5655 filesystem would be corrupt in the last block group.
5657 Fixed bug where if e2fsck tried to allocate a block to fix a
5658 filesystem corruption problem and the filesystem had no free blocks,
5659 ext2fs_new_block() would loop forever.
5661 The configure script now checks explicitly to see if "-static" works,
5662 since that can't be assumed to be true --- RedHat doesn't install
5663 libc-static by default.
5665 Fixed bug in libext2's block iterator functions where under some
5666 cirmcustances, file with holes would cause the bcount parameter to the
5667 callback function to be incorrect. This bug didn't affect any of
5668 e2fsprogs programs, but it was discovered by Paul Mackerras, the
5669 author of the PPC boot loader.
5671 Removed use of static variables to store the inode cache in libext2fs.
5672 This caused problems if more than one filesystem was accessed via
5673 libext2fs (static variables in libraries are generally a bad idea).
5674 Again, this didn't affect e2fsprogs programs, but it was discovered by
5677 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
5678 will compile cleanly with 1.2.13 kernels (even with a.out shared
5684 Added new functions to duplicate an ext2 filesystem handle, and its
5685 associated substructure. New functions: ext2fs_dup_handle(),
5686 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
5687 Other structures, such as the io_channel and the inode_cache, now have
5688 a ref count so that they only get freed when they are no longer used
5689 by any filesystem handle. (These functions were added as part of the
5690 development effort for an ext2 resizer).
5692 E2fsprogs 1.09 (April 14, 1997)
5693 ===============================
5695 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
5696 accidentally introduced in the 1.08 release. The overhead calculation
5697 was accidentally removed, which caused ext2fs_initialize() to not
5698 notice when the filesystem size needed to be adjusted down because
5699 there wasn't enough space in the last block group.
5701 Fixed bug in version parsing library routine; it was always parsing
5702 the library version string, instead of using the passed-in string.
5704 Clarified chattr man page.
5706 E2fsprogs 1.08 (April 10, 1997)
5707 ===============================
5709 E2fsck 1.07 was very slow when checking very large filesystems with a
5710 lot of files that had hard links (i.e., news spools). This was fixed
5711 by seriously revamping the icount abstraction. Added a formal test
5712 suite for the icount abstraction.
5714 Debugfs now has a "-l" option to the "ls" command, which lists the
5715 inode number, permissions, owner, group, size, and name of the files
5718 Fix a bug in e2fsck where when a directory had its blocks moved to
5719 another location during the pass 1b processing, the directory block
5720 list wasn't updated, so pass 2 wouldn't check (and correct) the
5721 correct directory block.
5723 E2fsck will now treat inodes which contain blocks which are claimed by
5724 the filesystem metadata by treating them as multiply claimed blocks.
5725 This way, the data in those blocks can be copied to a new block during
5726 the pass 1b--1d processing.
5728 E2fsck will attempt to determine the correct superblock number and
5729 display it in the diagnostic and warning messages if possible.
5731 Add support for a new (incompatible) feature, "sparse_super". This
5732 feature reduces the number of blocks which contain copies of backup
5733 superblocks and block group descriptors. (It is only an incompatible
5734 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
5735 support a new -s option; e2fsck will recognize filesystems built with
5736 this feature turned on.
5738 E2fsck now checks the library to make sure is the correct version,
5739 using new library functions. (This helps to diagnose incorrectly
5740 installed e2fsprogs distributions.)
5742 Dumpe2fs now prints more information; its now prints the the
5743 filesystem revision number, the filesystem sparse_super feature (if
5744 present), the block ranges for each block group, and the offset from
5745 the beginning of the block group.
5747 Mke2fs now distributes the inode and block bitmap blok so that the
5748 won't be concentrated in one or two disks in RAID/striping setups.
5749 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
5750 choose the largest blocks per group that be chosen. (For 2k blocks,
5751 you can have up to 16384 blocks/group; for 4k blocks, you can have up
5752 to 32768 blocks/group.) Previously mke2fs would not allow
5753 specification of more than 8192 blocks per group, even if you were
5754 using a 2k or 4k block group.
5759 Added a new function ext2fs_create_icount2() which takes a "hint"
5760 argument. This hint argument presets the icount array with the list
5761 of inodes which actually need to be in the icount array. This really
5762 helps to speed up e2fsck.
5764 Added a new function ext2fs_icount_validate() which checks the rep
5765 invariant for the icount structure. This is used mostly for testing.
5767 The error mesasage given when a bad inode number is passed to
5768 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
5769 EXT2FS_UNMARK_ERROR).
5771 Added a new function ext2fs_set_dir_block which sets the block of a
5772 dblist entry, given the directory inode and blockcnt.
5774 Added a new function ext2fs_get_library_version() which returns the
5775 current library version, and ext2fs_parse_version_string() which
5776 returns a version number based on a e2fsprogs version string.
5778 The icount functions will return EINVAL if the passed in inode number
5781 E2fsprogs 1.07 (March 9, 1997)
5782 ==============================
5784 E2fsck is now uses much less memory when checking really large
5785 filesystems (or rather, filesystems with a large number of inodes).
5786 Previously a filesystem with 1 million inodes required 4 megabytes of
5787 memory to store inode count statistics; that storage requirement has
5788 now been reduced to roughly half a megabyte.
5790 E2fsck can now properly deal with bad blocks appearing inside the
5791 inode table. Instead of trying to relocate the inode table (which
5792 often failed because there wasn't enough space), the inodes in the bad
5793 block are marked as in use.
5795 E2fsck will automatically try to use the backup superblocks if the
5796 primary superblocks have a bad magic number or have missing meta-data
5797 blocks (or meta-data blocks which are out of range).
5799 E2fsck's pass 3 has been made more efficient; most noticeable on
5800 filesystems with a very large number of directories.
5802 Completely revamped e2fsck's system of printing problem reports. It
5803 is now table driven, to make them more easily customizeable and
5804 extendable. Error messages which can be printed out during preen mode
5805 are now one line long.
5807 Fixed e2fsck's filesystem swapping code so that it won't try to swap
5808 fast symbolic links or deleted files.
5810 Fixed e2fsck core dumping when fixing a filesystem which has no
5811 directories (not even a root directory).
5813 Added a check to e2fsck to make sure that the length of every
5814 directory entry is a multiple of 4 (since the kernel complains if it
5817 Added a check to e2fsck to make sure that a directory entry isn't a
5818 link to the root directory, since that isn't allowed.
5820 Added a check to e2fsk to now make sure the '.' and '..' directory
5821 entries are null terminated, since the 2.0 kernel requires it.
5823 Added check to write_bitmaps() to make sure the superblock doesn't get
5824 trashed if the inode or block bitmap is marked as being block zero.
5826 Added checking of the new feature set fields in the superblock, to
5827 avoid dealing with new filesystem features that this package wasn't
5830 Fixed a fencepost error in ext2fs_new_block() which would occasionally
5831 try to allocate a block beyond the end of a filesystem.
5833 When the UUID library picks a random IEEE 802 address (because it
5834 can't find one from a network card), it sets the multicast bit, to
5835 avoid conflicting with a legitimate IEEE 802 address.
5837 Mke2fs now sets the root directory's owner to be the real uid of the
5838 user running mke2fs. If the real uid is non-zero, it also sets
5839 the group ownership of the root directory to be the real group-id of
5840 the user running mke2fs.
5842 Mke2fs now has more intelligent error checking when it is given a
5843 non-existent device.
5845 When badblocks is given the -vv option, it now updates the block that
5846 it is currently testing on every block.
5848 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
5849 currently correctly if PATH wasn't already set.
5851 Shared libraries now built with dependencies. This allows the shared
5852 library files to be used with dlopen(); it also makes the transition
5853 to libc 6 easier, since ld.so can tell which libc a particular shared
5854 library expects to use.
5859 Added new abstraction (defined in dblist.c) for maintaining a list of
5860 blocks which belongs to directories. This is used in e2fsck and other
5861 programs which need to iterate over all directories.
5863 Added new functions which test to see if a contiguous range of blocks
5864 (or inodes) are available. (ext2fs_*_bitmap_range).
5866 Added new function (ext2_inode_has_valid_blocks) which returns true if
5867 an inode has valid blocks. (moved from e2fsck code).
5869 Added new function (ext2fs_allocate_tables) which allocates the
5870 meta-data blocks as part of initializing a filesystem. (moved from
5873 Added a new I/O manager for testing purposes. It will either allow a
5874 program to intercept I/O requests, or print debugging messages to
5875 trace the activity of a program using the I/O manager.
5877 The badblocks_list functions now store the bad blocks in a sorted
5878 order, and use a binary search to speed up badblocks_list_test.
5880 The inode scan function ext2fs_get_next_inode() may now return a soft
5881 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
5882 those cases where part of an inode table is missing or there is a bad
5883 block in the inode table.
5885 Added a new function (ext2fs_block_iterate2) which adds new arguments to
5886 the callback function to return a pointer (block and offset) to the
5887 reference of the block.
5889 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
5890 application to jump to a particular block group while doing an inode
5893 The badblocks list functions were renamed from badblocks_* to
5894 ext2fs_badblocks_*. Backwards compatibility functions are available
5895 for now, but programs should be modified to use the new interface.
5897 Some of the library functions were reorganized into separate files to
5898 reduce the size of some programs which statically link against the
5901 Put in some miscellaneous fixes for the Alpha platform.
5904 E2fsprogs 1.06 (October 7, 1996)
5905 ================================
5907 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
5908 smash the backup copies in ext2fs_close(). (The problem was that when
5909 e2fsck -p discovered the problem, while it was closing the filesystem
5910 and exiting, it was also blowing away the backup superblocks on the
5911 disk, which was less than friendly.) We now make it the case that we
5912 only write out the backup superblock and the back block descriptors if
5913 the filesystem is completely free from problems.
5915 Fixed a bug in block_interate in the lib/ext2fs library which caused
5916 e2fsck to fail on GNU Hurd-created filesystems.
5918 Add support for Linux/FT's bootloader, which actually uses
5919 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
5922 Add support for the "A" (no atime update) attribute. (Note: this
5923 attribute is not yet in production kernels.)
5925 The test suite is not automatically run when doing a "make all" from
5926 the top level directory. Users should manually run "make check" if
5927 they wish to run the test suite.
5929 Upon a preenhalt(), make the printed message more explicit that
5930 running e2fsck "MANAULLY" means without the -p or -a options.
5932 In e2fsck, if a disconnected inode is zero-length, offer to clear it
5933 instead of offering to connect it to lost+found.
5935 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
5936 e2fsck to be run over it, change e2fsck to explicitly display this
5939 For dumpe2fs and e2fsck, cause the -V option to print out which
5940 version of the ext2fs library is actually getting used. (This will
5941 help detect mismatches of using a 1.06 utility with a 1.05 library,
5947 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
5948 the naming convention.
5950 In ext2fs_initialize(), make sure the description for the inode bitmap
5951 is correctly initialize.
5953 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
5955 E2fsprogs 1.05 (September 7, 1996)
5956 ==================================
5958 Add support for new fields in the ext2 superblock --- volume name,
5959 volume UUID, and last mounted field. Dumpe2fs displays these fields,
5960 tune2fs and mke2fs allows you to set them. E2fsck will automatically
5961 generate a UUID for those volumes that don't have them.
5963 Put in support for e2fsck to recognize HURD specific ext2 features ---
5964 most notably, the translator block. The e2fsprogs tools will now use
5965 the creator_os field in the superblock to correctly handle different
5966 OS-specific variants of the ext2 filesystem.
5968 E2fsck now fixes inodes which have a the deletion time set, but which
5969 have a non-zero i_link_count field by offering to clear the deletion
5970 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
5971 ext2 kernel behavior) and offered to unlink the file.
5973 If e2fsck sets the clean bit, but nothing else, set the exit code
5974 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
5975 set the filesystem valid bit when it was previously cleared. :-) This
5976 was needed to make the HURD fsck driver happy.
5978 If the user refuses to attach an unattached inode, e2fsck will no
5979 longer set the inode's link count. Otherwise, the inode would end up
5980 getting marked as unused, which might cause loss of data later.
5982 Make the message issued by e2fsck when the superblock is corrupt less
5983 confusing for users. It now mentions that another reason for the
5984 "corrupt superblock" message might be that the partition might not be
5985 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
5987 Make the libext2 library more robuest so that e2fsck won't coredump on
5988 an illegal superblock where the blocksize is zero. (f_crashdisk is
5991 By default, create filesystems where the default checkinterval is 6
5992 months (180 days). Linux servers can be robust enough that 20 reboots
5993 can be a long, long time.
5995 Added configure flag --enable-old-bitops, which forces the bitops to
5996 use the old (native) bitmask operations. By default on the sparc
5997 platform, the standard ext2 bit ordering is now used.
5999 Added a new feature to e2fsck to byte-swap filesystems; this can be
6000 used to convert old m68k filesystems to use the standard byte-order
6001 storage for the superblock, inodes, and directory blocks. This
6002 function is invoked by using the '-s' option to e2fsck.
6004 Debugfs's "dump" command has been enhanced so that it writes out the
6005 exact size of the file so that the nulls at the end of the file are
6006 eliminated. The command also accept a new "-p" option which will
6007 attempt preserve to preserve the ownernship, permissions, and
6008 file modification/access times.
6010 Debugfs has two new options, -f and -R. The -R option allows the user
6011 to execute a single debugfs command from the command line. The -f
6012 option allows the user to specify a "command file" containing debugfs
6013 commands which will get executed.
6015 Dumpe2fs now pretty prints the check interval, instead of just
6016 printing the check interval as a number of seconds.
6018 Fix bugs in debugfs: the params command when no filesystem is opened
6019 no longer causes a core dump. It is now possible to unlink a file
6020 when a pathame containing a '/' is specified.
6022 Tune2fs has a new -C option which sets the number of times the
6023 filesystem has been mounted.
6025 Fix the chattr '-v' option so that it actually works. Chattr was
6026 being buggy about the -v option parsing.
6031 The directory lib/uuid contains a set of library routines to generate
6032 DCE compatible UUIDs.
6034 Extended ext2fs_namei() to handle symbolic links. Added new function
6035 ext2fs_nami_follow() which will follow last symbolic link in the case
6036 where the pathname points to a sym link.
6038 The ext2fs_block_iterate function will now return the HURD translator
6039 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6040 iterator to return data blocks only. The ext2fs.h file now defines
6041 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6042 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6043 count field of the iterator callback function.
6045 The test script driver now takes an optional second argument, which is
6046 the test case to be run. This allows you to run a test case without
6047 needing to run the entire test suite.
6049 On Linux ELF systems, install the .so files in the correct places
6050 (/usr/lib). The .so files must be stored in the same directory as the
6053 Fixed miscellaneous HURD compilation issues with header file being
6054 included in the right order.
6056 Fixed debugfs so that it resets optind to zero, not one, since setting
6057 optind to zero is more correct.
6060 E2fsprogs 1.04 (May 16, 1996)
6061 =============================
6063 First "official" (1.03 was a limited release only) to support building
6064 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6067 This package includes a RPM specs file, that it can be built using the
6068 RedHat Package Manager.
6070 E2fsck now prints a hint that if there are lots of incorrectly located
6071 inode bitmaps, block bitmaps, and inode table blocks, the user might
6072 want to try using e2fsck -b 8193 first, to see if that fares any
6075 For ext2 filesystem written with the hurd, debugfs will now print out
6076 the translator field when printing an inode structure.
6078 Lots of miscellaneous linking/installation cleanups:
6080 Libraries are now linked using a relative pathname, instead of
6081 relying on -L working correct. It doesn't, in many cases, including
6082 current versions of GNU ld. This guarantees that the build tree is
6083 linking with the right libraries, instead of the ones installed in
6086 Header files, man pages, and the et/ss shell scripts are now
6087 generated using a custom substitution script, instead of relying on
6088 the configure script. This prevents needless recompilation of
6089 files; in addition, the custom substitution script is much faster.
6091 e2fsck may now be linked dynamically, by using the
6092 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6093 since it increases e2fsck's dependence on other files, but some
6094 people need to save disk space, and other critical programs on their
6095 systems were being linked dynamically anyway.
6097 Programs such as fsck which didn't need to be linked against
6098 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6099 only link against libraries they actually need. Otherwise, those
6100 programs would require the presense of libraries that otherwise
6101 could be removed from a rescuse diskette.
6103 The ss include files are now installed correctly so they can
6104 actually be used by another package.
6106 If the profiling libraries are built, they are now installed on a
6107 "make install-libs".
6110 E2fsprogs 1.03 (March 27, 1996)
6111 ===============================
6113 Change the m68k bit numbering for bitmasks to match the bit numbering
6114 used by all other ext2 implementations. (This change was requested by
6115 the m68k kernel development team.)
6117 Support (in-development) filesystem format revision which supports
6118 (among other things) dynamically sized inodes.
6120 Fixed a bug in the ext2 library so that an intelligent error is
6121 returned if mke2fs is run with a ridiculously small number of blocks
6124 Fixed a bug in the ext2 library which required that the device be
6125 openable in read/write mode in order to determine its size. This
6126 caused e2fsck -n to require read/write access when it was not
6127 previously necessary.
6129 Fixed a bug in e2fsck which casued it to occasionally fail the test
6130 suite depending on which version of the floating point library it was
6133 Fixed a bug in e2fsck so that it now halts with a fatal error when
6134 certain superblock consistency checks fail. Previously it continued
6135 running e2fsck, with some potential confusing/damaging consequences.
6137 Added new flag to fsck which allows the root to be checked in parallel
6138 with other filesytems. This is not the safest thing in the world to
6139 do, but some system administrators really wanted it.
6141 Fixed -Wall flames in lib/ss.
6144 E2fsprogs 1.02 (January 16, 1996)
6145 =================================
6147 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6149 Change e2fsck to print statistics of how many non-contiguous files are
6150 on the system. Note that a file which is larger than 8k blocks, it is
6151 guaranteed to be non-contiguous.
6153 In mke2fs, print a warning message if a user tries to format a whole
6154 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6155 whole disk, the -F (force) option forces mke2fs to format a whole disk
6158 Fix a bug in fsck where in some cases it might start checking
6159 partitions in the next pass before it finishes checking partitions in
6160 the current pass. This still won't cause two partitions on the same
6161 disk will be checked, so it's rarely a problem in real life.
6163 Patch lsattr so that it won't hang when checking a named pipe.
6165 Minor compilation fixes:
6166 * Fix the order of libraries that were linked in debugfs.
6167 * Allow the sources to be compiled with -ansi turned on.
