1 E2fsprogs 1.42.5 (July 29, 2012)
2 ================================
4 Fixed a bug with mke2fs where if there is only 8 inodes per block
5 group, the calculation of the number of uninitialized inodes in the
6 first block group would go negative. This resulted in "mke2fs -N 256
7 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
8 would run out of space. (Addresses Sourceforge Bug: #3528892)
10 Fixed a bug in how e2fsck would uniquify directory entry names.
11 (AddressesSourceforge Bug: #3540545)
13 Previously, e2fsck would only allow a mounted file system to be
14 checked if it was the root file system and it was mounted read-only.
15 Now it will allow any file system mounted read-only to be checked if
16 the -f option is specified. This makes it easier to test how e2fsck
17 handles checking file systems which are mounted without having to test
18 on the root file system.
20 Fixed a problem if e2fsck where if the root file system is mounted
21 read-only, e2fsck would not clear an error indication in the journal
22 superblock. Combined with a kernel bug, this would cause the e2fsck
23 to check the file system after every single boot.
25 The e4defrag program can now handle device symlinks, such as
26 /dev/mapper/testvg-testlv, instead of insisting on a less
27 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
30 Fixed filefrag so it will not crash with a segfault on files from a
31 virtual file system such as /proc. (e.g., "filefrag
34 Fixed filefrag so that it correctly reports the number of extents.
35 (Addresses Red Hat Bugzilla: #840848)
37 Fixed a file descriptor leak in logsave which could cause it to hang.
38 (Addresses Debian Bug: #682592)
40 Fixed e2fsck so that the file system is marked as containing an error
41 if the user chooses not to fix the quota usage information.
43 Fixed tune2fs so that it correctly removes the quota feature when the
44 last quota inode is removed.
46 Fix tune2fs so that after removing a quota inode, the block bitmap is
47 updated; otherwise, e2fsck would complain after running 'tune2fs -O
50 Fix tune2fs so that when converting a file system from using legacy
51 quota files to the new quota file system feature with hidden quota
52 files, the accounting for these files is handled correctly so that
53 e2fsck doesn't complain.
55 Improved e2fsck's verbose reporting statistics, and allow the more
56 verbose reporting to be enabled via /etc/e2fsck.conf.
58 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
60 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
66 Fixed portability problems on other operating systems (e.g., Hurd and
67 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
69 Make sure that shared libraries link with the shared libraries built
70 in the build tree, instead of the system provided libraries.
71 Previously, libraries and executables were linked with the system
72 libraries if present, and possibly using static archives instead of
73 shared libraries. This was also problematic since if libext2fs.so is
74 linked with a static libcom_err.a from system, the build system would
75 attempt to link without -lpthread. (Addresses Sourceforge Bug:
79 E2fsprogs 1.42.4 (June 12, 2012)
80 ================================
82 Fixed more 64-bit block number bugs (which could end up corrupting
83 file systems!) in e2fsck, debugfs, and libext2fs.
85 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
86 not properly propagating the journal's s_errno field to the superblock
87 field; it was not checking this field if the journal had already been
88 replayed, and if the journal *was* being replayed, the "error bit"
89 wasn't getting flushed out to disk.
91 Fixed a false positive complaint by e2fsck if all of the extents in
92 the last extent tree block are uninitalized and located after the end
93 of the file as defined by i_size.
95 The dumpe2fs will now display the journal's s_errno field if it is
96 non-zero, and it will also display the journal's 64-bit feature flag
99 Fix e2fsck so that it always opens the device file in exclusive mode
100 when it might need to modify the file system, and never if the -n
101 option is specified. (Previously, there were a few corner cases where
102 it might get things wrong in either direction.)
104 E2fsck now correctly truncates or deallocates extent-mapped inodes on
105 the orphan list. The root cause was a bug in libext2fs's block
106 iterator which could end up skipping an extent when the last block in
107 an extent is removed, causing the current extent to be removed from
110 E2fsck now correctly sets the global free block and inode counts when
111 truncating or removing inodes on the orphan list in preen mode.
112 Previously, it would leave these values would be set incorrectly,
113 which is largely a cosmetic issue since the kernel no longer pays
114 attention to those fields, but it can cause spurious complaints in
115 subsequent e2fsck runs.
117 Fix i_blocks accounting when the libext2fs library needs to add or
118 remove an extent tree block on bigalloc file systems.
120 The lsattr and chattr programs now support the No_COW flag for the
123 Debugfs now interprets date strings of the form @ddd as ddd seconds
124 after the beginning of the epoch. This is handy when setting an inode
125 number into the d_time field when debugging orphan list handling.
127 Fix a precedence bug with built-in quota support which might result in
128 e2fsck paying attention to the quota inode field even if the built-in
129 quota feature flag is not set. Fortunately, in practice that
130 superblock field should be zero for non-built-in quota file systems,
131 so it's unlikely this bug would have caused problems.
133 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
139 The regression test suite can now run the integration tests in the
140 tests directory in parallel, via "make -jN check".
142 Add new test, f_zero_extent_length which tests e2fsck's handling of
143 the case where all of the extents in the last extent tree block are
144 uninitialized extents after i_size.
146 Add a new test, f_jnl_errno, which checks handling of an error
147 indication set in the journal superblock.
149 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
152 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
153 tests e2fsck's handling of orphan inodes in preen mode, and truncation
154 of extent inodes on the orphan list.
156 Fixed more OS X portability issues.
159 E2fsprogs 1.42.3 (May 14, 2012)
160 ===============================
162 Fix a bug in the Unix I/O manager which could cause corruption of file
163 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
164 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
165 dumpe2fs to incorrectly display block numbers > 32-bits.
167 Improve the support for integrated quota files (where quota is a first
168 class supported feature using hidden files in the ext4 file system).
169 Previously the quota file was getting rewritten even when it was not
170 necessary, and e2fsck would erroneously try to hide quota files which
173 Quiet complaints in e2fsck when the total free blocks or inodes are
174 incorrect in the superblock after an system crash, since we don't
175 update nor depend on the superblock summaries at each commit boundary.
177 Fixed a regression introduced in 1.42.2 which would cause applications
178 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
179 would were still using the legacy 32-bit bitmaps) to crash. This was
180 due to missing 32-bit compat code in side the function
181 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
184 Fix a bug which would cause mke2fs to fail creating the journal if
185 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
188 Updated/fixed various man pages.
190 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
193 Fixed various Debian Packaging issues.
199 Change the nonsensically wrong types in the function signature of the
200 inline function ext2fs_find_first_zero_block_bitmap2(). This was
201 caused by a cut and paste error; fortunately no code in e2fsprogs used
202 this inline function, and there are any users of this functions
203 outside of e2fsprogs.
205 Add support for systems which have valloc(), but which do have
206 posix_memalign() nor memalign() (such as MacOS 10.5).
208 Refactor and clean up the allocation of aligned buffers for Direct I/O
209 support. Previously some allocations were requesting a greater
210 alignment factor that what was strictly necessary. Also optimize
211 reading and writing bitmaps using Direct I/O when the size of the
212 bitmap did not fully cover the file system blocksize.
214 Reserve the codepoints for the INCOMPAT features LARGEDATA and
217 Improved the regression test suite by adding some new integration
218 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
219 jbd2 format, as well as f_eofblocks which tests the new handling of
220 uninitialized and initialized blocks beyond i_size. Also add a new
221 unit test which verifies 32-bit bitmaps support and the new
222 find_first_zero primitives.
224 Add a few dependencies to fix parallel (make -j) builds.
226 Removed bash'isms which were breaking the regression test suite on
227 systems where /bin/sh is not bash.
229 The config.guess and config.sub have been updated to the 2012-02-10
232 Fix a portability problem caused by assuming the present of mntent.h
233 means that setmntent() exists. Instead, explicitly test for this in
234 the configure script.
236 If the sys/signal.h header file does not exist, don't try to include
237 it, since it's not available on all systems.
239 Add support for systems that do not support getpwuid_r()
241 The configure script now supports a new option,
242 --enable-relative-symlinks, which will install relative symlinks for
243 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
245 When building BSD shared libraries make sure the LDFLAGS variable is
246 passed to the linker. Fixing this allows, for example, e2fsprogs to
247 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
250 Fix gcc -Wall nitpicks
253 E2fsprogs 1.42.2 (March 27, 2012)
254 =================================
256 The resize2fs program uses much less CPU and is much faster for very
257 large file systems. (Addresses Debian Bug: #663237)
259 The seti and freei commands in debugfs can now take an optional length
260 argument to set and clear a contiguous range of inodes.
262 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
263 plan to remove support for it from the kernel file system driver. It
264 really wasn't very useful and was causing more problems than it
265 solves. Since e2fsck will complain if inodes that should have
266 EOFBLOCKS_FL do not have the flag set, we are going to remove this
267 check from e2fsprogs first, and then only remove the flag from the
270 The mke2fs program can now use direct I/O via "mke2fs -D". This will
271 slow down the mke2fs, but it makes it more polite on a loaded server
272 by limiting the amount of memory that gets dirtied by mke2fs when it
273 is using buffered I/O.
275 E2fsck was needlessly closing and re-opening the file system as a side
276 effect of adding Multiple Mount Protection (MMP). This isn't
277 necessary for non-MMP file systems, so drop it.
279 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
280 can more easily diagnose memory allocation failures caused by
281 insufficient memory. E2fsck will now abort if there are memory
282 allocation failures when the file system is initially opened and
283 during the block group descriptor checks. (Addresses Google Bug:
286 If there are incorrect block group checks, e2fsck will now report the
287 incorrect and corrected checksum values.
289 The e2fsck progam can now write log files containing the details of
290 the problems that were found and fixed directly, via configuration
291 parameters in /etc/e2fsck.conf.
293 Added the ability to limit the number of messages reported by e2fsck
294 for a given problem type. This avoids a potential bottleneck if there
295 is a serial console which can cause a boot sequence to take a long
296 time if e2fsck needs to report many, many file system errors.
298 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
299 them to use much less memory for large file systems.
301 The dumpe2fs program will now print the expected block group checksum
302 if it is incorrect. This helps to diagnose problems caused by
303 incorrect block group checksums.
305 E2fsck now checks for extents with a zero length, since the kernel
306 will oops if it comes accross such a corrupted data structure. (See
307 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
309 E2fsck has a number of bugs relating to discard that have been fixed.
310 (1) Fixed a bug which could cause e2fsck to discard portions of the
311 inode table which were actually in use. (2) E2fsck will now avoid
312 using discard if the block device doesn't zero data on discard, since
313 otherwise this could cause problems if the file system gets corrupted
314 in the future. (3) E2fsck will now avoid using discard when it is run
315 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
316 discards in the last block group.
318 E2fsck's CPU utilization in pass 5 has been optimized, which will
319 speed up e2fsck slightly.
321 E2image will now skip copying uninitialized bitmap and inode table
324 Fixed mke2fs -S so it does not corrupt the first block group's
327 E2fsck will now check the new sysfs interface to determine if we are
328 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
330 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
332 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
337 Fixed various portability issues for non-Linux systems, particularly
338 MacOS X, as well as Linux systems running with the just-released glibc
341 Fix file descriptor leak in ext2fs_close() if the file system with
342 uninit_bg is opened read/only with a backup superblock. (Addresses
343 SourceForge Bug: #3444351)
345 Fixed an invalid return in a non-void function in the quota code.
346 (Addresses SourceForge Bug: #3468423)
348 Fixed the debian rules file so that the calls to dpkg-buildflags works
349 when the shell is dash.
351 The debian package build now uses V=1 so that there is more
352 information about potential build failures in debian buildd logs.
354 If the uninit flags get cleared by functions such as
355 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
356 superblock is marked dirty and the block group descriptor checksum is
357 updated if necessary.
359 The debian rules file will now try to load debian/rules.custom of it
360 exists. This flie can skip various builds for speed reasons if there
361 is no need for the e2fsck-static or udeb packages. Available
362 customizations in the rules file includes SKIP_STATIC=yes,
363 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
365 In addition, if the file misc/mke2fs.conf.custom.in exists in the
366 source tree, it will be used instead of the standard misc.conf file in
367 the upstream sources. This makes it easier for Debian-derived systems
368 to distribute a custom mke2fs.conf file without having to worry about
369 merge issues if future versions of e2fsprogs makes changes in the
370 upstream default version of mke2fs.conf.
373 E2fsprogs 1.42.1 (February 17, 2012)
374 ===================================
376 The mke2fs and e2fsck now use significantly less memory when creating
377 or checking very large file systems. This was enabled by adding
378 extent-based bitmaps which are stored using a red-block tree, since
379 block and inode allocations tend to be contiguous.
381 The command mke2fs -S is used as a last ditch recovery command to
382 write new superblock and block group descriptors, but _not_ to destroy
383 the inode table in hopes of recovering from a badly corrupted file
384 system. So if the uninit_bg feature is enabled, mke2fs -S will now
385 set the unused inodes count field to zero. Otherwise, e2fsck -fy
386 after using mke2fs -S would leave the file system completely empty.
388 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
389 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
390 installed an mke2fs binary using that name.
392 The usage and help messages for the -G, -t and -T options in mke2fs
395 If e2fsck needs to use the backup group descriptors, the
396 ext2fs_open2() function clears the UNINIT bits to ensure all of the
397 inodes in the file systems get scanned. However, the code which reset
398 the UNINIT flags did not also recalculate the checksum, which produced
399 many spurious (and scary) e2fsck messages. This has been fixed by
400 resetting cheksums when the UNINIT bits are cleared.
402 Relax a check in e2fsck which required that the block bitmap to be
403 initialized when the inode bitmap is in use. This will allow us to
404 eventually eliminate code from the kernel which forcibly initialized
405 the block bitmap when the inode bitmap is first used, requiring an
406 extra journal credit and disk write. (Addresses Google Bug: #5944440)
408 Make sure rdebugfs (which may be installed setuid or setgid disk) does
409 not honor environment variables if euid != uid or egid != gid.
411 Debugfs's ncheck command has been optimized and now is much more
412 robust with faced with corrupted file systems. The ncheck command
413 also now has a -c option which will verify the file type information
414 in the directory entry to see if matches the inode's mode bits. This
415 is extremely useful when trying to use debugsfs to determine which
416 parts of the file system metadata can be trusted.
418 E2image will try to use ftruncate64() to set the i_size for raw
419 images, instead of writing a single null byte. This avoid allocating
420 an extra block to the raw image, for those file systems and/or
421 operating systems that support this. (Linux does.) In addition, fix
422 a logic bug that caused the file to not be properly extended if the
423 size of the last hole was exactly an multiple of a megabyte.
425 Fixed a bug in resize2fs where for 1k and 2k file systems, where
426 s_first_data_block is non-zero, this wasn't taken into account when
427 calculate the minimum file system size for use with the -M option.
429 Fixed the badblocks program to honor the -s flag when in read-only -t
430 mode. (Addresses Debian Bug #646629)
432 Update Czech, Dutch, French, Polish, and Sweedish translation from the
435 Fixed various Debian Packaging issues so that dpkg-buildflags is used
436 if present, which allows e2fsprogs to be built with security hardening
437 flags. (Addresses Debian Bugs: #654457)
442 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
443 This was only an issue for programs compiled against e2fsprogs 1.41
444 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
447 The libext2fs library now uses sysconf() to fetch the page size, instead
448 of the deprecated getpagesize().
450 The ext2fs_get_pathname() function will return a partial path if an a
451 directory in the path is not a directory, displaying it as an inode
452 number in angle brackets instead of giving up and displaying an error.
453 This is much more helpful when a user is trying to debug a corrupted
456 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
458 Added a new library function, ext2fs_file_get_inode_num(), for use by
461 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
462 file, it actually works.
464 The block iterator now properly honors the BLOCK_ABORT flag for
465 extent-based flags. Previously, it didn't, which generally made code
466 be less efficient, but it could cause bugs in ext2fs_link(), for
467 example, by causing it to insert multiple directory entries.
469 Fixed an (harmless other than causing a compiler warning) use of an
470 uninitialized variable in e2fsck's MMP code.
473 E2fsprogs 1.42 (November 29, 2011)
474 ==================================
476 This release of e2fsprogs has support for file systems > 16TB. Online
477 resize requires kernel support which will hopefully be in Linux
478 version 3.2. Offline support is not yet available for > 16TB file
479 systems, but will be coming.
481 This release of e2fsprogs has support for clustered allocation. This
482 reduces the number of block (now cluster) bitmaps by allocating and
483 deallocating space in contiguous power-of-2 collections of blocks,
484 which are called clustered. This is a file system level feature,
485 called 'bigalloc', which must be enabled when the file system is
486 initially formatted. It is not backwards compatible with older
489 Added support for the Multi-Mount Protection (MMP) feature.
491 E2fsck more efficiently uses scratch files for really big file
492 systems. (This is a feature that has to be turned on explicitly; see
493 [scratch_files] in the e2fsck.conf man page.)
495 Fix a bug in e2fsck where if the free blocks and inodes counts are
496 incorrect, e2fsck would fix them without printing an error message.
497 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
498 any explanation of what was fixed.
500 E2fsck will no longer attempt to clone an extended attribute block in
501 pass1b handling if the file system does not support extended
504 E2fsck will be more careful accidentally asking the user to continue
505 if the file system is mounted, so that an escape sequence won't cause
506 a false positive. (Addresses Debian Bug: #619859)
508 E2fsck now uses less cpu time in pass 5 when large portions of the
509 bitmaps are uninitialized.
511 E2fsck will no longer segault when a corrupted file system has a bad
512 extent, and removing it leads to a block needing to be deallocated.
513 (Addresses SourceForge Bug: #2971800)
515 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
516 and print debugging information to make it easier to find potential
519 E2fsck will check to see if the bad block inode looks insane, and will
520 skip trying to use if it certain fields which should be zero look
521 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
522 to get confused and do more harm than good.
524 If e2fsck modifies certain superblock fields which the kernel doesn't
525 look at, it will now mark the superblock as dirty without marking the
526 file system as changed. This avoids signalling the init scripts that
527 a reboot is necessary, since the kernel isn't going to look at those
528 fields, so it won't care if they have been changed.
530 Fixed a bug in the libext2fs library (in the binary search routine of
531 the icount abstraction) that could (very, very rarely) cause e2fsck to
532 die in the middle of pass 1 or pass 2 processing.
534 E2fsck will not try to do a discard operation if the -n option was
535 specified on the command line.
537 E2fsck now supports an extended "discard" option which will cause
538 e2fsck to attempt discard all unused blocks after a full, successful
541 E2fsck will check for the bad block inode to make sure it looks sane
542 before trusting it, to avoid causing more harm than good to the file
545 E2fsck now returns additional status bits in its exit code if it
546 aborts early in the e2fsck run.
548 E2fsck now correctly calculates the maximum file size in the case of
549 the huge_file file system feature enabled without extents.
551 The mke2fs and e2fsck programs now tries to use the punch hole command
552 as a "discard" when operating on normal files.
554 The e2image program now supports the qcow2 format, which is a more
555 efficient way of capturing file system dumps.
557 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
558 per-device defaults to be specified in the configuration file.
560 Mke2fs now supports the reserved_ratio relation in the [defaults] and
561 [fs_types] section in mke2fs.conf.
563 Mke2fs now creates extent-mapped directories for the root and
564 lost+found directories.
566 Mke2fs will skip zero'ing the journal if the extended option
567 "lazy_journal_init" is specified. This can save a lot of time, but it
568 does add a small amount of risk if the system crashes before the
569 journal is overwritten entirely once. It is epsecially useful for
572 Mke2fs will now create file systems that enable user namespace
573 extended attributes and with time- and mount count-based file
574 system checks disabled.
576 Mke2fs will not set a stride or strip size of one block based on block
577 device attributes obtained from sysfs.
579 Mke2fs now displays a progress report during the discard process.
581 Mke2fs now handles extreme file system parameters correctly which
582 previously caused the inodes per group to drop below 8, leading to a
583 segfault. (The inodes per group must be a multiple of 8, but the code
584 didn't correctly deal with an inodes per group count less than 8.)
586 Mke2fs and tune2fs previously would give an error if the user tried
587 setting the stride and stripe-width parameters to zero; but this is
588 necessary to disable the stride and stripe-width settings. So allow
589 setting these superblock fields to zero. (Addresses Google Bug:
592 Mke2fs now gives a warning if the auto-detected block size exceeds the
595 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
596 is the default), mke2fs will now set the s_max_mnt_count superblock
597 field to -1, instead of 0. Kernels older then 3.0 will print a
598 spurious message on each mount then they see a s_max_mnt_count set to
599 0, which will annoy users. (Addresses Debian Bug: #632637)
601 The default mke2fs.conf now has entries for "big" and "huge", which
602 are needed for very big file systems.
604 The resize2fs program now has support for a new online resize ioctl
605 that can support file systems > 16TB, once it arrives in v3.x kernels.
607 Fixed bug which caused resize2fs to fail when shrinking an empty file
608 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
610 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
612 Allow tune2fs to remove external journals if the device can not be
615 Debugfs's icheck will now correctly find inodes which use the
616 searched-for block as an extended attribute block.
618 Debugfs now has a new "punch" command which remove blocks from the
621 Debugfs now has a new "e2freefrag" command which analyzes the free
622 space fragmentation of the file system, using the same code as the
625 Debugfs now has a "filefrag" command which displays information about
626 a file's fragmentation.
628 Add support to build a metadata-only, read-only, stripped-down version
629 of debugfs called rdebugfs.
631 Fixed a potential stack overrun bug in debugfs.
633 The badblocks program now correctly recovers from I/O errors when
634 direct I/O is being used. The badblocks command now also supports a
635 -B option which forces the use of buffered I/O, and the -v option will
636 provide a more detailed breakdown of read, write, and failed
639 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
641 Added support for journals larger than 2GB.
643 Support using both hard links and symlinks when installing e2fsprogs.
645 Add overflow checking to tune2fs -i's fsck interval, which must fit in
648 The debugfs command now has a new 'blocks' command which prints out
649 data blocks of a particular inode in a format which is useful for
652 Filefrag will report 0 extents correctly in verbose mode. (Addresses
653 RedHat Bugzilla: #653234)
655 Filefrag has been fixed so its -v report prints the correct expected
656 block number (previously there had been an off-by-one error). In
657 addition, it will now display the number of contiguous extents when -v
658 is not specified. This makes it consistent with the number of extents
659 printed when the -v option was specified. In addition, the number of
660 contiguous extents is far more interesting/useful than the number of
661 physical extents for very large files. (Addresses Debian Bug:
664 Logsave's usage message has been fixed. (Addresses Debian Bug:
667 Avoid an infinite loop in ext2fs_find_block_device() if there are
668 symlink loops in /dev caused by a buggy udev.
670 Added a useful "fallocate" program to the contrib directory.
672 Fixed an ABI compatibility problem in libext2fs which broke the dump
673 program. Also added back some macros which dump needed so it could
674 compile against the latest version of ext2_fs.h (Addresses Debian Bug:

701 by using the configure option --enable-quota.
703 Reserved the on-disk fields for the metadata checksum and snapshot
704 features, which are currently in development.
706 The ext2fs library now has the new functions ext2fs_punch(),
707 ext2fs_get_memzero() and ext2fs_file_get_inode().
709 The ext2fs library now has support for calculating the crc32c checksum
710 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
712 The I/O manager now supports the discard operation.
714 Reserved file system code points for new 1st class quota feature.
716 Shortened the compilation lines by moving the autoconf defines to
717 a config.h header file.
719 Fixed a potential free of an unitialized pointer in
720 ext2fs_update_bb_inode().
722 Fixed miscellaneous gcc -Wall and coverity warnings.
724 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
726 Fixed a build failure when OMIT_COM_ERR is defined.
728 Improved error checking and fixed memory leaks caused by error return
731 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
732 the fsync() to be skipped.
734 Added a test for extent-mapped journals by mke2fs and tune2fs.
736 Added a test for creating a large (over 4GB) journal using mke2fs.
738 Added a test to make sure the inode size remains constant.
740 The regression test script now prints the list of which tests failed.
742 The regression test system now uses /tmp for its scratch files, which
743 is often a tmpfs mounted file system and hence much faster.
745 The i_e2image test was fixed so it works with valgrind.
747 Tests that rely on debugfs are now skipped if debugfs wasn't built.
749 Fixed the dependencies for "make check" so all required dependencies
750 are built before running the gression tests.
752 A link to com_err.h is installed in $(includedir) during a "make install".
754 The po/*.gmo files are automatically rebuilt if they are missing or
755 out of date. This helps out Debian packaging.
757 Allow ext2fs_get_memalign() to compile on systems that don't have
760 Fixed a namespace leak in libext2fs (tdb_null).
763 E2fsprogs 1.41.14 (December 22, 2010)
764 =====================================
766 Fix spurious complaint in mke2fs where it would complain if the file
767 system type "default" is not defined in mke2fs.conf.
769 The resize2fs program will no longer clear the resize_inode feature
770 when the number reserved group descriptor blocks reaches zero. This
771 allows for subsequent shrinks of the file system to work cleanly for
772 flex_bg file systems.
774 The resize2fs program now handles devices which are exactly 16T;
775 previously it would give an error saying that the file system was too
778 E2fsck (and the libext2fs library) will not use the extended rec_len
779 encoding for file systems whose block size is less than 64k, for
780 consistency with the kernel.
785 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
786 been fixed. (Addresses Sourceforge Bug: #3138115)
788 The ext2fs_block_iterator2() function passed an incorrect ref_offset
789 to its callback function in the case of sparse files. (Addresses
790 Sourceforge Bug: #3081087)
792 Fix some type-punning warnings generated by newer versions of gcc.
795 E2fsprogs 1.41.13 (December 13, 2010)
796 =====================================
798 E2fsck now supports the extended option "-E journal_only", which
799 causes it to only do a journal replay. This is useful for scripts
800 that want to first replay the journal and then check to see if it
803 E2fsck will now support UUID= and LABEL= specifiers for the -j option
804 (which specifies where to find the external journal). (Addresses
807 E2fsck now has support for the problems/<problem code>/force_no
808 configuration option in e2fsck.conf, which forces a problem to not be
811 Dumpe2fs will now avoid printing large negative offsets for the bitmap
812 blocks and instead print a message which is a bit more helpful for
813 flex_bg file systems.
815 Mke2fs will now check the file system type (specified with the -t
816 option) to make sure it is defined in the mke2fs.conf file; if it is
817 not, it will print an error and abort. If the usage type (specified
818 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
819 warning but will continue. (Addresses Debian Bug #594609)
821 Clarified error message from resize2fs clarifying that on-line
822 shrinking is not supported at all. (Addresses Debian Bug #599786)
824 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
825 displayed. (Addresses Debian Bug #555456)
827 E2fsck will open the external journal in exclusive mode, to prevent
828 the journal from getting truncated while it is in use due to a user
829 accidentally trying to run e2fsck on a snapshotted file system volume.
830 (Addresses Debian Bug #587531)
832 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
835 The tune2fs program can now set the uninit_bg feature without
838 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
839 default mount options settings which were added in 2.6.35.
841 The e2fsck and dumpe2fs programs now support the new ext4 superblock
842 fields which track where and when the first and most recent file
843 system errors occurred. These fields are displayed by dumpe2fs and
844 cleared by e2fsck. These new superblock fields were added in 2.6.36.
846 Debugfs now uses a more concicse format for listing extents in its
847 stat command. This format also includes the interior extent tree
848 blocks, which previously was missing from stat's output for
851 Debugfs has a new option, -D, which will request Direct I/O access of
854 Mke2fs will skip initializing the inode table if a device supports
855 discard and the discard operation will result in zero'ed blocks.
857 Badblocks will now correctly backspace over UTF-8 characters when
858 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
859 Debian Bugs #583782 and #587834)
861 E2freefrag will now display the total number of free extents.
863 Resize2fs -P no longer requires a freshly checked filesystem before
864 printing the minimum resize size.
866 Fixed a floating point precision error in a binary tree search routine
867 that can lead to seg fault in e2fsck and resize2fs.
869 Fixed a bug in e2fsck where if both the original and backup superblock
870 are invalid in some way, e2fsck will fail going back to the original
871 superblock because it didn't close the backup superblock first, and
872 the exclusive open prevented the file system from being reopened.
874 Fixed a big in e2freefrag which caused getopt parsing to fail on
875 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
877 Clarified an mke2fs error message so a missed common in an -E option
878 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
879 results in a more understandable explanation to the user.
881 Mke2fs now displays the correct valid inode ratio range when
882 complaining about an invalid inode ratio specified by the user.
884 Mke2fs now understands the extended option "discard" and "nodiscard",
885 and the older option -K is deprecated. The default of whether
886 discards are enabled by default can be controled by the mke2fs.conf
889 Mke2fs's handling of logical and physical sector sizes has been
890 improved to reflect the fact that there will be some SSD's with 8k and
891 16k physical sectors arriving soon. Mke2fs will no longer force block
892 size to be the physical sector size, since there will be devices where
893 the physical sector size is larger than the system's page size, and
894 hence larger than the maximal supported block size. In addition, if
895 the minimal and optimal io size are not exported by the device, and
896 the physical sector size is larger than the block size, the physical
897 sector size will be used to set the Raid I/O optimization hints in the
900 E2fsck will now display a better, more specific error message when the
901 user enters a typo'ed device name, instead of blathering on about
902 alternate superblocks.
904 Fixed various Debian Packaging Issues
906 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
907 #589345, #591083; Addresses Launchpad Bug: #505719)
909 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
910 Polish, Swedish, and Vietnamese translations.
916 Fix a dependency definition for the static and profiled blkid
917 libraries which could cause compile failures in some configurations.
918 (Addresses Debian Bug: #604629)
920 Add support for Direct I/O in the Unix I/O access layer.
922 Fixed a memory leak in the Unix I/O layer when changing block sizes.
924 Fixed minor memory leaks in mke2fs.
926 Added a new function to the ext2fs library, ext2fs_get_memalign().
928 The tst_super_size test program will check to make sure the superblock
929 fields are correctly aligned and will print them out so they can be
930 manually checked for correctness.
932 Fixed some makefile dependencies for test programs in lib/ext2fs.
934 Reserved the feature flags and superblock fields needed for the Next3
937 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
938 EXT4_INCOMPAT_EA_INODE.
941 E2fsprogs 1.41.12 (May 17, 2010)
942 ================================
944 Mke2fs now gives a correct error message if the external journal
945 device is not found. (Addresses Red Hat Bug #572935)
947 Resize2fs -P will now refuse to print a minimum size if the file
948 system is not clean. Previously it would go ahead and print a minimum
949 size anyway, which might not be correct, leading to user confusion.
951 E2fsck now tests for extents that begin at physical block 0 and
952 rejects them as invalid. (Addresses Google Bug: #2573806)
954 Fixed a bug in e2fsck which could cause it to crash when trying to
955 remove an invalid extent and the block bitmaps hadn't yet been loaded.
956 (Addresses SourceForge Bug: #2971800)
958 E2fsck now will completely skip time-based checks if the system clock
959 looks insane or the option broken_system_clock is set in
962 E2fsck would previously report an i_blocks corruption for a 4T file
963 created using posix_fallocate; this bug has been fixed.
965 E2fsck will now correctly mark a sparse journal as invalid and will
966 delete and recreate the journal to address the problem.
968 E2fsck would previously incorrectly ask the user whether she would
969 like to abort the file system check after finding a problem --- and
970 then abort regardless of the user's answer. This is annoying, and
973 E2fsck can now continue even if it fails to recreate the resize
974 inode; previously it would just abort the file system check
977 E2fsck could potentially remove directory entries for inodes found in
978 the unused region of the inode table; this would generally happen on
979 ext4 file systems that do not use journaling. This bug has been fixed
980 by not clearing these directory entries once it has been established
981 that bg_unused_inodes may not be trustworthy; once pass #2 has been
982 completed, e2fsck will restart the file system check from the
983 beginning, and then it will be safe to delete any directory entries
984 pointing to inodes that appear to be deleted. (Addresses Google Bug:
987 E2fsck will not try to set the block group checksums if the user
988 cancels the fsck with a control-C. It's a bad idea to set the
989 checksums if e2fsck hasn't been completed, and it often results an the
990 error message, "Inode bitmap not loaded while setting block group
991 checksum info". (Addresses Launchpad Bug: #582035)
993 The mke2fs program now queries the kernel for the physical as well as
994 the logical sector size, and will not allow a blocksize below the
995 logical, and will strongly encourage a blocksize at least as big as
996 the physical blocksize. This is needed for 4k sector drives that
997 emulate 512 byte sector sizes.
999 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
1000 rarely needed, but it is a legal value.
1002 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1003 not needed, and offer to clear it; this is a sign of a kernel bug, but
1004 more importantly, some released kernels may crash when this situation
1005 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
1007 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1008 i_size is correct. (Kernels starting with 2.6.34 will set
1011 The com_err library will now only output ^M (a CR character) when the
1014 Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
1015 and Vietnamese translations.
1017 Fixed various Debian packaging issues --- see debian/changelog for
1018 details. (Addresses Debian Bugs: #571247, #563487)
1024 The regression test suite now uses its own mke2fs.conf file, so that
1025 downstream distributions want change the mke2fs.conf file which is
1026 distributed in the RPM or dpkg file, without worrying about screwing
1027 up the regression test results.
1029 Always build namei.o so that building with configure --disable-debugfs
1030 works correctly. Long-term, if we care about reduced e2fsprogs
1031 builds, we need a more general solution for deciding what .o files are
1032 needed for a particular build. Given that install floppies are going
1033 (gone?) the way the dodo bird, we probably don't care, though.
1034 (Addresses Sourceforge Bug: #2911433)
1036 Add configure options --enable-symlink-build and
1037 --enable-symlink-install, which allow e2fsprogs be built using
1038 symlinks instad of hard links, and to be installed using symlinks
1039 instead of hard links, respectively. It is useful when the file
1040 system where the build is taking place, or the file system where
1041 e2fsprogs is installed, can't handle hard links for some reason.

1051 device has been resized beyond 2**32 blocks. (Addresses Launchpad
1054 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
1055 the allocation status of the block <blk>. (Addresses Debian Bug:
1058 E2fsck now prints a much more emphatic and hopefully scary message
1059 when a file system is detected as mounted while doing a read/write
1060 check of the filesystem. Hopefully this will dissuade users from
1061 thinking, "surely that message doesn't apply to *me*" :-(
1063 E2fsck -n will now always open the file system read-only. We now
1064 disallow certain combination of options which previously were manual
1065 exceptions; this is bad because it causes users to think they are
1066 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
1067 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
1069 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
1070 it detected a badly aligned partition. Unfortunately, this broke some
1071 distribution installation scripts, so it now just prints the warning
1072 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
1073 Launchpad Bug: #530071)
1075 Mke2fs would take a long time to create very large journal files for
1076 ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
1079 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
1080 2.6.34 kernels to make e2fsck not complain about blocks deliberately

1083 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
1084 e2fsck -fD can corrupt non-indexed directories when are exists one or
1085 more file names which alphabetically sort before ".". This can happen
1086 with ext2 filesystems or for small directories (take less than a lock)

1210 is mounted. (Addresses Launchpad bug: #416648)
1212 Update Czech, Indonesian, Polish and Vietnamese translations (from the
1213 Translation Project).
1215 Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)

1218 details. (Addresses Debian Bugs: #540111)
1223 The configure script supports the --with-cc, --with-ccopts, and
1224 --with-ldopts options. Instead, the more standard use of CC=,
1225 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
1226 Also, --with-ld, which never worked, was also removed.

1235 Work around a bug in autoconf 2.64.
1238 E2fsprogs 1.41.9 (August 22, 2009)
1239 ==================================
1241 Fix a bug in e2fsck routines for reallocating an inode table which
1242 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
1243 filesystem feature with a relatively rare (and specific) filesystem
1244 corruption. This fix causes e2fsck to try to find space for a new
1245 portion of the inode table in the containing flex_bg, and if that
1246 fails, the new portion of the inode table will be allocated in any
1247 free space available in the filesystem.
1249 Make e2fsck less annoying by only asking for permission to relocate a
1250 block group's inode table once, instead of for every overlapping
1251 block. Similarly, only ask once to recompute the block group
1252 checksums, instead of once for each corrupted block group's checksum.
1254 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
1255 not present, and it needs to fall back to using the FIBMAP ioctl.
1257 Fix filefrag to correctly print the number of extents for zero-length
1258 files. (Addresses Debian Bug: #540376)
1260 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
1261 to more easily debug the FIBMAP code.
1263 Fixed filefrag for non-extent based files.
1265 Add a new program, e2freefrag, which displays information about the
1266 free space fragmentation in an ext2/3/4 filesystem.
1268 Fix inode resizing via tune2fs -I so that it works correctly in the
1269 face of non-empty bad blocks inodes, and if the filesystem was
1270 formatted using the "mke2fs -E stride=N" option for RAID arrays.
1272 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
1273 and corrupt large directories if the directory needs to shrink by more
1274 than one block. (Addresses Debian Bug: #537510)
1276 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
1277 last mount times are in the future, they are corrected even if
1278 buggy_init_scripts is set. This is needed because otherwise resize2fs
1279 will refuse to resize the filesystem, even after running "e2fsck -f".
1280 (Addresses Launchpad bug: #373409)
1282 E2fsck will now print much fuller information when the last mount time
1283 or last written time is in the future, since most people can't seem to
1284 believe their distribution has buggy init scripts, or they have a
1285 failed CMOS/RTS clock battery.
1287 Enhance dumpe2fs to dump the extent information via the 'stat'
1288 command, and more detailed extent information via the new command
1291 Update French, Polish, Czech, and Sweedish translation from the
1292 Translation Project.
1294 Fixed various Debian packaging issues --- see debian/changelog for
1300 Fixed miscellaneous gcc -Wall warnings.
1302 Fixed memory leak in error path in ext2fs_block_iterate2()
1304 Fixed non-Linux build of the intl directory by adding support for the
1307 The bitmap read/write functions now treat uninitialized bitmaps as
1308 unallocated; this fixes a number of problems in all e2fsprogs for ext4
1309 filesystems when there is a need to allocate new blocks or inodes, and
1310 there aren't any free blocks or inodes in the already-used block
1313 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
1314 get inserted into the extent tree when they are not needed.
1317 E2fsprogs 1.41.8 (July 11, 2009)
1318 ================================
1320 Fix resize2fs's online resizing, fixing a regression which in
1321 e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
1323 Fix potential filesystem corruptions caused by using resize2fs to
1324 shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
1327 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
1328 setgid and the currently running program doesn't have write access to
1329 the uuidd work directory.
1331 Add safety checks (for non-Linux systems) so that uuidd isn't run with
1332 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
1333 will be careful not to close the file descriptor for its unix domain
1334 socket when it detaches itself from the controlling tty. Also add
1335 safety checks so that if the unix domain socket between the uuid
1336 library and uuidd program is closed for any reason, both the library
1337 and the uuidd will return an appropriate error code instead of looping
1338 in an infinite loop.
1340 The e2croncheck script, which creates an LVM snapshot and then checks
1341 the ext3/4 filesystem via the LVM snapshot, has been added to the
1344 Fix filefrag program for files that have more than 144 extents.
1346 Update French, Polish, Czech, Indonsian, and Sweedish translation from
1347 the Translation Project.
1349 Fixed various Debian packaging issues --- see debian/changelog for
1350 details. (Addresses Debian Bug #535530)
1352 Update/clarify man pages.
1357 Fix compilation problem when configured with --disable-uuid.
1359 Don't build uuidgen if configured with --disable-uuid.
1361 Add the new library function ext2fs_test_inode_bitmap_range(), and
1362 optimized ext2fs_test_block_bitmap_range(), which will be needed for
1363 future optimizations for e2fsck.
1365 Fix makefile dependencies for libcom_err so that the Makefiles work
1366 well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
1368 Enhance the build system so that the full set of commands executed by
1369 the Makefiles are displayed, instead of the Linux kernel summary
1370 output, if the build was configured with --enable-verbose-makecmds, or
1371 if GNU make is in use and the V variable is non-null, i.e., via "make
1375 E2fsprogs 1.41.7 (June 29, 2009)
1376 ================================
1378 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
1379 uninitalized data into the portion of the inode beyond the first 128
1380 bytes when operating on inodes mapped via extents; potentially
1381 corrupting filesystems.
1383 Fix memory leaks in e2fsprogs, including a very large memory leak
1384 which can cause e2fsck to run out of memory when checking very large
1385 filesystems using extents.
1387 The logsave program will now filter out the ^A and ^B characters when
1388 writing to the console.
1390 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
1391 end of the block even if the directory block is corrupted.
1393 Fix debugfs from core dumping if the logdump command fails to open the
1396 Enhance badblocks to print the currently tested block number when
1397 interrupted with ^C.
1399 Fix lsattr to exit with a non-zero status when it encounters errors.
1400 (Addresses RedHat Bugzilla #489841)
1402 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
1403 filesystems as the kernel when encoding rec_len >= 64k. For 64k
1404 filesystems (currently all that is supported by e2fsprogs, this is
1405 only a minor corner case).
1407 Resize2fs will now update the journal backup fileds in the sup0erblock
1408 if the journal is moved; this avoids an unnecessary full fsck after
1409 resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
1411 Fix libext2fs to properly initialize i_extra_size when creating the
1412 journal and resize inodes.
1414 Change badblocks to allow block sizes larger than 4k.
1416 Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
1418 Update Chinese and Czech translation from the Translation Project.
1420 Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
1426 Add --disable-libuuid option to configure which uses an in-system
1427 installed version of libuuid; the private version is enabled by
1430 Add --valgrind-leakcheck option to the test_script program which runs
1431 valgrind with the appropriate options to find memory leaks.
1434 E2fsprogs 1.41.6 (May 30, 2009)
1435 ===============================
1437 Fix a critical regression in e2fsck introduced version 1.41.5 which
1438 can undo updates to the block group descriptors after a journal replay.
1440 If e2fsck receives an I/O error while replaying the journal, prompt
1441 the user whether they want to ignore the error or not; if e2fsck is
1442 run in preen mode, force fsck to abort the preen pass.
1444 Fix a bug which would cause e2fsck to core dump if the filesystem
1445 contains a corrupt extent header, and the user declines to clear the
1446 inode. (Addresses Sourceforge Bug: #2791794)
1448 Fix e2fsck to restart only once in the case of multiple block groups
1449 which inodes in use that are in the uninitialized part of the block
1450 group's inode table.
1452 To reduce user confusion, if the /etc/mtab file is missing
1453 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
1454 new, explicit error code to indicate this case. This will cause
1455 e2fsck to give a clearer error message when the user is using buggy
1456 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
1459 Fix e2fsck so that if the primary group descriptors are corrupted, but
1460 the backup superblock is entirely invalid, to go back to using (and
1461 fixing) the priary group descriptors instead of completely giving up
1462 on the filesystem. (Addresses Debian Bug: #516820)
1464 Change e2fsck to not abort a preen pass if an inode is found to have
1465 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
1466 kernels (post 2.6.29) will ignore this field. So let's fix it
1467 automatically during the preen pass instead of forcing the user to fix
1468 this up manually. (Addresses Debian Bug: #526524)
1470 Add resource tracking for e2fsck passes 1b through 1d.
1472 Speed up e2fsck by eliminating unnecessary journal checks if the
1473 filesystem is already mounted and doesn't need recovery (since the
1474 kernel would have run the journal when the filesystem was mounted.)
1475 Also speed up e2fsck by avoiding unnecessary block group descriptor
1476 updates in ext2fs_close().
1478 Add support to chattr to migrate inodes from using direct/indirect
1481 Avoid corrupting the filesystem if there is an attempt to shrink a
1482 filesystem using resize2fs smaller than posible by making
1483 ext2fs_set_bmap() more careful not to delete the old block until the
1484 new block can be inserted. In addition, fix a bug in how the minimum
1485 size of the filesystem (plus a safety margin) is calculated, and
1486 modify resize2fs to refuse to shrink the filesystem below that minimum
1487 size without the force flag.
1489 Teach blkid to try to figure out DM device names using take advantage
1490 of information in sysfs when running on kernels (2.6.29 and later)
1491 which provide this information in /sys/block/dm-<N>/dm/name; this is
1492 much faster than scanning for the devncie number in /dev/mapper.
1494 Fix blkid to prefer /dev/mapper/<name> device names instad of the
1495 private /dev/dm-X names.
1497 Add an -a option to debugfs's close_filesys command which writes any
1498 changes to the superblock or block group descriptors to all of the
1499 backup superblock locations.
1501 Add support to the filefrag program to use the FIEMAP ioctl.
1503 Update Chinese translation from the Translation Project.
1505 Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
1506 Launchpad Bug: #381854)
1508 Fixed various Debian packaging issues --- see debian/changelog for
1509 details. (Addresses Debian Bug #506064)
1515 Add test code to make sure e2fsck's problem.c doesn't have two problem
1516 codes assigned to duplicate values.
1518 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
1519 (Addresses Sourceforge Bug: #2780205)
1521 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
1522 function declaration for init_resource_track() and
1523 print_resource_track() when RESOURCE_TRACK is not defined.
1525 The test code which is used to build the tst_csum progam has been
1526 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
1527 avoid compile problems caused by not having a prototype for
1528 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
1530 Update the config.guess and config.sub file to the latest from the
1531 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
1532 Debian Bug: #528330)
1534 Add a new function, ext2fs_extent_open2(), which behaves like
1535 pext2fs_extent_open(), but uses the user-supplied inode structure
1536 when opening an extent instead of reading the inode from disk.
1539 E2fsprogs 1.41.5 (April 23, 2009)
1540 =================================
1542 Fix a number of filesystem corruption bugs in resize2fs when growing
1543 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
1546 Debugfs can now set i_file_acl_high via the set_inodes_field command,
1547 and print a 64-bit file acl. This is useful for debugging filesystem
1548 corruptions where the high bits of i_file_acl_high are set. E2fsck
1549 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
1550 since some Linux kernel versions pay attention to this field even when
1553 Speed up e2fsck when checking clean filesystems by avoiding
1554 unnecessary block reads, and coalescing the block group descriptor
1555 blocks so they are read using a single read operation.
1557 The libuuid library will now close all file descriptors before running
1558 uuidd. This avoids problems when the calling program has open sockets
1559 which then never get closed because uuidd is a long-running helper
1560 daeomn. (Addresses Launchpad bug: #305057)
1562 In order to avoid unnecessary full filesystem checks by e2fsck after
1563 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
1564 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
1566 Mke2fs will avoid trying to create the journal when run in
1567 superblock-only mode (mke2fs -S), since the left-over journal in the
1568 inode table will cause mke2fs to fail.
1570 Fix a bug in libext2fs functions that check to see if a particular
1571 device or filesystem image is mounted, which would cause these
1572 functions to report that a file identical to the (relative) pathname
1573 used by a pseudo-filesystem was mounted when in fact it was not.
1575 Update Czech translation from the Translation Project.
1577 Add Chinese (simplified) translation from the Translation Project.
1579 Fix support for external journals (which was broken in e2fsprogs
1582 Fix a regression in debugfs where the "stat" command when no
1583 filesystem was open would cause debugfs to crash with a segmentation
1586 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
1587 used to support filesystems without a journal. Update the blkid
1588 library so it understands this.
1590 The blkid library will remove an entry from the blkid cache
1591 representing the entire disk if partitions are found, since presuambly
1592 the device previously had no partition table, but has now transitioned
1593 to using a partition table.
1595 Add a check to mke2fs and tune2fs that the argument to the -m option
1596 (which specifies the reserved ratio) must be greater than zero.
1597 (Addresses Debian Bug: #517015)
1599 Add support for tracking the number kilobytes written to the
1600 filesystem via the superblock field s_kbytes_written. It will be
1601 updated by the kernel as well as by e2fsprogs programs which write to
1602 the filesystem. This is useful for tracking the wear to filesystems
1603 on Solid Sstate Drives.
1605 Fix compatibility issue in the libext2fs info file and makeinfo
1606 version 4.12. (Addresses Red Hat Bugzilla: #481620)
1608 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)

1622 Add support for building the blkid command statically.
1624 Add support for disabling the built-in blkid library in favor of a
1625 system-installed blkid implementation via the configure option
1629 E2fsprogs 1.41.4 (January 27, 2009)
1630 ===================================
1632 Fixed a bug which could sometimes cause blkid to return an exit value
1633 of zero for a non-existent device (Addresses Debian Bug: #502541)
1635 Blkid will now recognize ext3 filesystems that have the test_fs flag
1636 set as ext3 filesystems.
1638 The blkid library will now recognize btrfs filesystems and swap
1639 devices currently used by user-level software suspend.
1641 Tune2fs now updates the block group checksums when changing the UUID
1642 to avoid causing e2fsck to complain vociferously at the next reboot.
1644 Tune2fs's inode size resizing algorithms have been fixed so it is not
1645 vastly inefficient for moderate-to-large filesystems, due to some
1646 O(n**2) and O(n*m) algorithms that didn't scale well at all.
1648 Fix tune2fs's inode resizing algorithm so it will not corrupt
1649 filesystems laid out for RAID filesystems; in addition, tune2fs will
1650 refuse to change the inode size for filesystems that have the flex_bg
1651 feature enabled. (This is a limitation in the current implementation
1654 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
1655 filesystems with 32-bit block numbers, when the headers for 64-bit
1656 block numbers was added. This regression has been fixed.
1658 Debugfs's ncheck command has been fixed to avoid printing garbage
1659 characters at the end of file names.
1661 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
1662 when shrinking filesystems with uninit_bg feature would not be moved.
1663 In addition, blocks and inode table blocks were not being correctly
1664 freed when shrinking filesystems with the flex_bg feable, which caused
1665 resize2fs -M to fail. Finally, when blocks are moved, make sure the
1666 uninitialized flag in extents is preserved.
1668 Fix bug which caused dumpe2fs to abort with an error if run on a
1669 filesystem that contained an external journal.
1671 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
1672 for this in argv[0] to provide better legacy support for these
1673 distributions. This is a practice that should NOT be continued,
1676 Mke2fs now has a new option -U, which allows the user to specify the
1677 UUID that should be used for the new filesystem.
1679 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
1680 minus one block. This allows users who have read that ext3 supports
1681 up to 16TB filesystems and who create a 16TB LVM to not get confused,
1682 since the true limit is really 16TB minus one block.
1684 E2fsck will no longer abort an fsck run if block group has an errant
1687 E2fsck now distinguishes between fragmented directories and fragmented
1688 files in verbose mode statistics and in the fragcheck report.
1690 Fix a bug in e2fsck which casued it double count non-contiguous
1691 extent-based inodes.
1693 E2fsck will leave some slack space when repacking directories to allow
1694 room for a few directory entries to be added without causing leaf
1695 nodes to be split right away.
1697 Fix a bug which caused e2fsck to crash when it comes across a
1698 corrupted interior node in an extent tree with the error message:
1699 "Error1: Corrupt extent header on inode XXXXXX"
1701 E2fsck problem descriptions involving the journal are no longer
1702 referred to as "ext3" problems, since ext4 filesystems also have
1705 Fix a long-standing bug in e2fsck which would cause it to crash when
1706 replying journals for filesystems with block sizes greater than 8k.
1708 Update Catalan translation from the Translation Project.
1710 Fixed various Debian packaging issues --- see debian/changelog for
1711 details. (Addresses Debian Bugs: #503057, #502323, #511207)
1716 Fix build of e2fsck.profiled, and add support for building profiled
1717 binaries in the misc directory if configured with --enable-profile.
1719 The ext2fs_open() function now performs more sanity checks on the
1720 superblock to avoid potential divide by zero errors by other parts of
1723 The ext2fs_read_inode_full() function now has a safety check to avoid
1724 a segmentation fault on corrupted filesystems.
1726 The ext2fs_new_inode() function now has a sanity check so that if the
1727 s_first_inode field in the superblock is insane, it will return
1728 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
1730 To avoid segmentation faults, ext2fs_block_alloc_stats() and
1731 ext2fs_inode_alloc_stats() now validates the passed inode or block
1732 number to avoid overrunning an array boundary.
1734 Various signed/unsigned errors for variables containing block numbers
1737 Accomodations for gcc's stupidity in not realizing that constant
1738 strings that do not contain a '%' character are safe to use in format
1739 strings have been made so that distributions that want to compile
1740 e2fsprogs with -Werror=format-security have an easier time doing so.
1742 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
1744 Added the utility make-sparse.c to the contrib directory.
1746 The ext2fs_block_iterate2() function now reflects errors from
1747 ext2fs_extent_set_bmap() to the caller, if the callback tries to
1748 change a block on an extent-based file, and ext2fs_extent_set_bmap()
1749 fails for some reason (for example, there isn't enough disk space to
1750 split a node and expand the extent tree.
1752 The ext2fs_block_iterate2() function will preserve the uninit flag in
1753 extents when the callback function modifies a block in an extent-based
1756 E2fsck will now flag filesystems that have an insane s_first_ino field
1757 in their superblock, and attempt to use a backup superblock to repair
1761 E2fsprogs 1.41.3 (October 12, 2008)
1762 ===================================
1764 E2fsck has been fixed so it prints the correct inode number for
1765 uinit_bg related problems.
1767 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
1768 is available on linux. This can be disabled via a configuration
1769 option in /etc/e2fsck.conf.
1771 Fix a file descriptor leak in libblkid when checking to see if an ext4
1772 or ext4dev module exists.
1774 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
1775 while trying to close a filesystem can lead to infinite loops.
1776 (Addresses Red Hat Bugzilla #465679)
1778 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
1779 will cause resize2fs to drop into an infinite loop. (Addresses Red
1780 Hat Bugzilla: #465984)
1782 Add a check in the Unix I/O functions in libext2fs so that when a
1783 device is opened read/write, return an error if the device is
1784 read-only using the BLKROGET ioctl.
1786 Fix debugfs's ncheck command so that it prints all of the names of
1787 hardlinks in the same directory.
1789 Fix a bug in libblkid so it correctly detects whether the ext4 and
1790 ext4dev filesystems are available, so that the ext4dev->ext4

1803 E2fsprogs 1.41.2 (October 2, 2008)
1804 ==================================
1806 Fix e2fsck's automatic blocksize detection. This fixes a regression
1807 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
1808 specifies a block number using the -b option if the blocksize option
1809 isn't also specified using -B. Unfortunately, users very commonly
1810 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
1811 superblock; in fack e2fsck will often suggest this kind of command
1814 Enhance the debugfs's "ncheck" command so it will print all of the
1815 pathnames for the specified inodes. (Previously, in some cases ncheck
1816 might not print a pathname for an inode at all if some of the other
1817 inodes had multiple hard links.)
1819 Enhance debugfs's "hash" command so the hash seed can be specified via
1820 a command-line option. In addition, allow the hash algorithm to be
1821 specified by name instead of just by number.
1823 Fix e2fsck so that we don't accidentally print the translation file's
1824 header when asking the user a custom question so there is no prompt
1825 defined for a particular problem record. For example, the question
1826 "Run journal anyway" will get the PO header tacked on because e2fsck
1827 erroneously passed the null string to _(). (Addresses Launchpad Bug:

1908 E2fsprogs 1.41.1 (September 1, 2008)
1909 ====================================
1911 Many people are forgetting to update their mke2fs.conf file, and this
1912 causes ext3, ext4, and ext4dev filesystems won't get created with the
1913 proper features enabled. We address this in two ways. First, mke2fs
1914 will issue a warning if there is not definition for an ext3, ext4, or
1915 ext4dev filesystem and the user is trying to create such a filesystem
1916 type. Secondly, when installing from a source build, "make install"
1917 will provide basic configuration file handling for /etc/mke2fs.conf.
1918 If it exists, and does not mention ext4dev, it will be moved aside to
1919 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
1920 be installed. If the existing /etc/mke2fs.conf file does mention
1921 ext4dev, then "make install" will install official mke2fs.conf file as
1922 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
1923 they should look to see if any changes need to be merged.
1925 The mke2fs program will now create the journal in the middle of the
1926 filesystem, since this minimizes seek times on average for fsync-heavy
1927 workloads. In addition, mke2fs will now create journals using extents
1928 for filesystems that support them. This results in a more efficient
1929 encoding for the journal since it eliminates the need for using
1932 The mke2fs program will avoid allocating an extra block to the
1933 journal. (Addresses Sourceforge Bug: #1483791)
1935 Mke2fs will correctly enforce the prohibition against features
1936 (specifically read-only features) in revision 0 filesystems. (Thanks
1937 to Benno Schulenberg for noticing this problem.)
1939 Mke2fs previously would occasionaly create some slightly non-optimally
1940 placed inode tables; this bug has been fixed.
1942 The mke2fs and tune2fs programs now print the correct usage message
1943 describing the maximum journal size. (Addresses Debian Bug: #491620)
1945 Add support for setting the default hash algorithm used in b-tree
1946 directories in tune2fs (from a command-line option) or mke2fs (via
1947 mke2fs.conf). In addition, change the default hash algorithm to
1948 half_md4, since it is faster and better.
1950 The blkid library will now recognize MacOS hfsx filesystems, and
1951 correctly extract the label and uuid for hfs, hfsx, and hfsplus
1952 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
1954 The blkid library has improved detection of JFS and HPFS filesystems.
1955 (Addresses Launchpad Bug: #255255)
1957 The blkid library is now much more efficiently handling devicemapper
1958 devices, mainly by no longer using the devicemapper library. This can
1959 speed up access for systems with a large number of device mapper
1962 Blkid had a number of cache validation bugs in libblkid that have been
1963 fixed. (Addresses Debian Bug: #493216)
1965 Resize2fs will now properly close out the "updating inode references"
1966 progress bar so there is a newline printed before printing the final
1967 "resize is successful" message.
1969 Resize2fs will now correctly handle filesystems with extents and/o
1970 uninitialized block groups correctly when file/directory blocks need
1971 to relocated (i.e., when shrinking a filesystem or if the resize_inode
1972 is not present). To support this, the ext2fs library now supports
1973 initializing inode and block bitmaps that are not yet initialized when
1974 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
1975 addition, e2fs_block_iterate2() can now support changing the location
1976 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
1977 been optimized to avoid creating unnecessary new extents when updating
1978 the location of blocks in the extent tree. This will also help out
1979 e2fsck's recovery of obscurely corrupted filesystems with extents,
1980 when blocks are claimed by multiple inodes.
1982 Add support for on-line resizing ext4 filesystem with the flex_bg
1983 filesystem feature. The method for doing so is not optimal, but to do
1984 a better job will require kernel support.
1986 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
1987 debugfs programs to not be able to read e2image files; the signed
1988 vs. unsigned bug in the code which read bitmaps from the e2image has
1989 been fixed. (Addresses Debian Bug: #495830)
1991 Resize2fs is now correctly managing the directory in-use counts when
1992 shrinking filesystems and directory inodes needed to be moved from one
1993 block group to another. This bug has been around since e2fsprogs
1994 1.26, and is largely harmless, but does cause a filesystem corruption
1995 which will be flagged by e2fsck after the filesystem has been shrunk.
1997 E2fsck will no longer issue spurious complaints about the inode size
1998 caused by very large extent-based files, and by blocks reallocated
1999 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
2000 Kernel Bugzilla: #11341)
2002 Mke2fs will now set the creation timestamp on the lost+found directory
2003 and the root directory. (More generally, all new inodes created using
2004 the ext2fs library will correctly set the creation timestamp.)
2006 E2fsck now correctly calculates ind/dind/tind statistics in the
2007 presence of extent-based files. In addition, "e2fsck -v" will report
2008 statistics of the depth of extent trees in the filesystem. E2fsck can
2009 also give an inode fragmentation report using "e2fsck -E fragcheck"
2010 which can be useful when debugging the kernel block allocation
2013 Fix support for empty directory blocks in ext4 filesystems with 64k
2014 blocksize filesystems.
2016 E2fsck will now print the depth of corrupt htree directories.
2018 Debugfs's htree command now correctly understands extent-based
2019 directories. It will also print out the minor hash as well as the
2022 Debugfs has a new command which will print the supported features of
2023 e2fsprogs, to enable scripts to know whether the installed version of
2024 e2fsprogs can support a specific feature.
2026 Debugfs will now write files using extents for filesystems that
2029 The error message printed by "tune2fs -I" if the inode size was too
2030 small was rather confusing, so it has been improved. Also, we won't
2031 try to create an undo log until we know that command-line-specified
2032 parameters such as "tune2fs -I <inode size>" are valid.
2034 Given some filesystems found "in the wild" that had non-zero block
2035 group checksums even though the uninit_bg/gdt_sum feature was not
2036 enabled, e2fsck would issue spurious error messages. Teach
2037 ext2fs_group_desc_csum_verify() to ignore the block group checksum
2038 entirely if the feature flag is not set. (Addresses Debian Bug:
2041 The blkid program will now print out a user-friendly listing of all of
2042 the block devices in the system and what they contain when given the
2043 -L option. (Addresses Debian Bug: #490527)
2045 The filefrag program now has a more accurate calculation for the
2046 number of ideal extents. (Addresses Debian Bug: #458306)
2048 The test I/O manager is now enabled by default, but its overhead is
2049 only incurred when it would be enabled via the TEST_IO_FLAGS or
2050 TEST_IO_BLOCK environment variables.

2121 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
2122 top-level Makefile. That automatic rule is used to better support
2123 SCCS, but it caused problems for a particular niche distribution which
2124 likes to use configure.sh files to store the configure options used to
2125 build a package. Unfortuntaely GNU make will use the configure.sh to
2126 replace the configure script, resulting in a self-inflicted fork bomb
2127 leading to an out-of-memory crash.
2129 To support old GNU C compilers don't use C99/C++ comments, but only
2130 K&R style comments, and don't try to use __builtin_expect if __GNUC__
2131 is less than 3. (__builtin_expect is only supported for gcc versions
2132 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
2133 this is an optimization, we only try to use __builtin_expect for gcc 3
2136 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
2137 __LITTLE_ENDIAN, which are only defined by glibc's header files and
2138 hence isn't portable.
2140 For the convenience for some distributions that need a static tune2fs,
2141 the Makefile for misc/ now has a tune2fs.static target.
2143 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
2144 for extent-based files
2146 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
2149 All source files no longer have any trailing white space.
2151 The io_channel_read_blk64() and io_channel_write_blk64() functions are

2165 * Scripts do not assume that /bin/true is always in /bin
2166 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
2167 * Flush stdio handles before calling setbuf(), since Solaris will
2168 discard any pending output to the stream.
2169 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
2170 picky about which C compiler can beused for SUSv3 conformance.
2171 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
2172 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
2173 Since we need some SUSv3 functions, consistently use SUSv3 so
2174 that e2fsprogs will build on Solaris using c99.
2175 * Solaris C99 does not support varargs C preprocessor macros
2176 * Solaris header files pollute the C namespace if in/netinet.h
2177 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
2179 * Solaris ships with a pathetically ancient shell in /bin/sh so we
2180 avoid the use of various more avanced shell constructs such as $().
2182 The "make rpm" command will now take some extra configure optiosn from
2183 the build environment without needing to patch the source tree.
2185 The ext2fs_add_dir_block() function will now grow the dblist more
2186 aggressively as an optimization to avoid copying the array too often.
2188 The e2fsck_write_bitmaps() will write the block and inode bitmaps
2189 together instead of in two passes.
2192 E2fsprogs 1.41 (July 10, 2008)
2193 ==============================
2195 Add support for ext4 filesystem features, in particular extents,
2196 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
2197 support for checking journal checksums. Debugfs will print new
2198 superblock and inode fields that were defined for ext4. For example,
2199 the nanosecond and i_version fields of an inode, and the
2200 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
2201 Note: Resize2fs doesn't currently support the combination of flex_bg
2202 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
2204 Tune2fs can support migrating a filesystem from using 128 byte inodes
2205 to 256 byte inodes, so it can take advantage of the full features of
2208 Add support for "undo" support. E2fsck and mke2fs can optionally
2209 record an undo log which can replayed by the program e2undo.
2211 E2fsck could damage a filesystem by trying to relocate inode tables
2212 due to corrupted block group descriptors, where the attempted inode
2213 table relocation would do far more harm than good. E2fsck has been
2214 fixed to detect this these sorts of corrupted block group descriptors
2215 much earlier in e2fsck processing, so it can try to use the backup
2216 superblock and block group descriptors first. This should be a much
2217 better strategy for recovering these types of corrupted filesystems.
2218 (Addresses Sourceforge Bug: #1840291)
2220 E2fsck will display a more understandable message when the last check
2221 field in the superblock is in the future. (Addresses Debian Bug:

2225 attributes stored in the inode.
2227 Enhance mke2fs to print a more explanatory error message when
2228 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
2231 Fix mke2fs to use a default block size of 4k when formatting an
2232 external journal device. This is done by using a fixed filesystem
2233 type list that consists only of the single filesystem type "journal"
2234 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
2235 Debian Bug: #488663)
2237 Speed up how mke2fs writes the journal data blocks by writing the disk
2238 blocks in larger chunks.
2240 Fix blkid handling of stale devices. Fix a bug which could cause a
2241 core dump while garbage collecting the blkid cache, and assure that
2242 blkid_find_dev_with_tag() never returns a non-existent device. Also,
2243 if a filesystem is found at a new /dev location, eliminate any
2244 duplicate stale entries which can not be verified.
2245 (Addresses Debian Bugs: #487758, #487783)
2247 Add more paranoid checks for LVM volumes and swap partitions in
2248 blkid's probe function, to reduce the chances of false positives.
2250 The mke2fs program now has a much more sophisticated system for
2251 controlling configuration parameters of a newly created filesystem
2252 based on a split filesystem and usage type system. The -t option to
2253 mke2fs was a deprecated alias to -c; it now specifies a filesystem
2254 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
2255 separated usage list. The filesystem type information and type
2256 information is used to extract configuration parameters from the
2257 /etc/mke2fs.conf file.
2259 The mke2fs program will no longer complain and request the -f option
2260 when the user tries to create a filesystem with greater than 2**31
2263 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
2264 adjust the mke2fs.conf file so filesystems for the Hurd are created
2265 with a blocksize of 4096 and inode size of 128, which is all it knows
2266 how to handle. (Addresses Debian Bug: #471977)
2268 Mke2fs will always make sure that lost+found always has at least 2
2269 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
2271 Resize2fs will now print the minimum needed filesystem size if given
2272 the -P option, and will resize the filesystem to the smallest possible
2273 size if given the -M option.
2275 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
2276 blocks are consumed during an off-line resize.
2278 The "ls" command in debugfs now supports the -p option, which causes
2279 it to quote the filenames so that spaces or tabs in directory entries
2280 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses

2343 numbers; in particular, the I/O manager functions, the test_io,
2344 inode_io, and unix_io managers have all be converted to support 64-bit
2347 Debugfs can now be extended for use by test programs. See
2348 lib/ext2fs/extents.c for an example for how it can be used. The test
2349 program links against the debugfs object files, and provides
2350 additional commands by defining an auxiliary libss command table.
2352 The lazy_bg filesystem feature, which was only used by developer's
2353 testing, has been removed since it has been largely supplanted by
2354 uninit_bg. This also simplifies the code.
2357 E2fsprogs 1.40.11 (June 17, 2008)
2358 =================================
2360 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
2361 percentage of reserved blocks. (Addresses Debian Bug: #452639)
2363 Updated Spanish and Catalan translations.
2365 Fixed various Debian packaging issues --- see debian/changelog for
2366 details. (Addresses Debian Bugs: #483962, #483023)
2368 Add detection for ZFS volumes to the libblkid library.
2370 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2371 (Addresses Debian Bug: #486463)
2376 Fix marginal C code in probe_lvm2() function to the blkid library more
2377 portable for older compilers.
2379 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
2381 Fix ext2fs_swap{16,32,64} functions so they can be used by external
2382 applications on big-endian machines. (Addresses Debian Bug: #484879)
2385 E2fsprogs 1.40.10 (May 21, 2008)
2386 ================================
2388 When deciding whether or not to revalidate a blkid cache entry, if the
2389 device's mtime is newer than the last time the cached entry was
2390 validated, force a revalidation.
2392 Fix a potential data corruption bug in e2fsck in the journal replay.
2393 The chances of this is happening is extremely remote, especially the
2394 default data=ordered or data=writeback modes. However, if a block
2395 which has been journalled starts with the first four bytes 0xc03b3998,
2396 when e2fsck replays the journal, those four bytes will be replaced
2397 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
2398 metadata to begin with those fatal 4 byte sequence, and unless
2399 data=ordered mode is in use, data blocks are never journaled.
2401 Updated German, Dutch, Sweedish, and Vietnamese translations.
2406 Fixed various Debian packaging issues --- see debian/changelog for
2409 Remove default sizes of types when cross compiling, since autoconf
2410 2.50 can figure this out automatically now.
2413 E2fsprogs 1.40.9 (April 27, 2008)
2414 =================================
2416 SuSE's security team audited uuidd and came up with a few minor
2417 issues. None of them are serious given that uuidd runs setuid as a
2418 unprivileged user which has no special access other than libuuid
2419 directory, but it's good to get them fixed.
2421 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
2422 work correctly with in-inode extended attributes.
2424 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
2427 Debugfs will avoid using a pager if the standard output is not a tty.
2429 Fix debugfs and tune2fs to correctly handle daylight savings time when
2430 parsing a time string.
2432 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2434 Fix fsck completion bars when multiple filesystems were being checked
2435 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
2436 #203323, Addresses Sourceforge Bug: #1926023)
2438 Fix fsck so that progress information is sent back correctly when
2439 multiple filesystems are being check and the output of fsck is being
2440 redirected to a file descriptor. Also, include the device name (w/o
2441 spaces) in the progress information sent back via a file descriptor.
2442 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
2445 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
2447 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
2448 signal to its child process.
2450 Fix mke2fs's creation of are resize inode when there is a non-standard
2451 s_first_data_block setting.
2453 Fix bug in blkid when run by an unprivileged user; most devices were
2454 not reported correctly. 9Addresses Launchpad Bug: #220275)
2456 Mke2fs will not allow the logically incorect combination of
2457 resize_inode and meta_bg, which had previously caused mke2fs to create
2458 a corrupt fileystem.
2460 Fix fsck in German locales so that a 'j' means yes.
2461 (Addresses Sourceforge Bug: #1947683)
2467 Fixed various Debian packaging issues --- see debian/changelog for
2470 Update valgrind options in test_script to work with valgrind 3.2.3
2472 Update texinfo.tex to a much newer version from the FSF.
2474 Remove bashism for configure script and from the lib/ss Makefile.
2475 Addresses Sourceforge Bug: 1921969
2477 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
2479 Fix build system so that if texinfo is not installed, it won't print a
2480 (harmless) error message.
2483 E2fsprogs 1.40.8 (March 13, 2008)
2484 =================================
2486 Fixed e2image -I so it works on image files which are larger than 2GB.
2488 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
2489 the size is larger than the number of blocks found in the inode, don't
2490 try to allocate extra empty blocks at the end of the directory to make
2491 up the difference; there's no point to doing that. In addition, if
2492 the size is not a multiple of a blocksize, always fix it.
2494 E2fsck handled a pass 2 "should never happen error" by not giving
2495 enough information and then core dumping. Unfortunately, it was all
2496 too easy to trigger the "should never happen" situation if a
2497 directory's inode size was not correct. This has been fixed, but
2498 e2fsck has also been taught how to handle this situation more
2499 gracefully, by simply removing the inode hash tree information, so
2500 that it can be rebuilt again after e2fsck's pass 3. (Addresses
2501 Launchpad Bug: #129395)
2503 Resize2fs had a bug resizing large inodes with extended attributes
2504 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
2505 completely on big-endian systems such as PowerPC. The bug should be
2506 completely fixed now. Yay for regression test suites. (Addresses Red
2507 Hat Bugzilla: #434893)
2509 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
2510 translations. Many thanks to Philipp Thomas from Novell for stepping
2511 up to become the new German translation maintainer! (Addresses Debian
2512 Bugs: #302512, #370247, #401092, #412882).
2514 When e2fsck is clearing a corrupt inode's HTREE directory information,
2515 make it clear that it is just clearing the HTREE information, not the
2518 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2523 Add new functions, ext2fs_dblist_get_last() and
2524 ext2fs_dblist_drop_last(), which allows the caller to examine the last
2525 directory block entry added to the list, and to drop if it necessary.
2527 Fixed a portability problem in libblkid with DJGPP.
2529 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
2530 to Philipp Thomas for pointing this out.
2532 If the info files are not built, change "make install" so it doesn't
2533 fail with an error code.
2536 E2fsprogs 1.40.7 (February 28, 2008)
2537 ====================================
2539 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
2540 depreciate the -s option, since it can result in filesystems which
2541 e2fsck can't fix easily. There are very good reasons for wanting to
2542 disable sparse_super; users who wants to turn off sparse_super can use
2543 debugfs. (Addresses Sourceforge Bug: #1840286)
2545 Add missing options to mke2fs's usage message. (Addresses Sourceforge
2548 Fix bug in resize2fs when large (greater than 128 byte) inodes are
2549 moved when a filesystem is shrunk; it was only moving the first 128
2550 bytes, so extended attributes were not getting moved. (Addresses Red
2551 Hat Bugzilla: #434893)
2553 E2fsck now prints an explicit message when the bad block inode is
2554 updated, to avoid confusion about why the filesystem was modified.
2555 (Addresses Sourceforge Bug: #756460)
2557 Allow mke2fs and tune2fs manipulate the large_file feature.
2558 Previously we just let the kernel and e2fsck do this automatically,
2559 but e2fsck will no longer automatically clear the large_file feature.
2560 It still isn't really necessary to worry about this feature flag
2561 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
2564 Suppress message about an old-style fstab if the fstab file is empty.
2565 (Addresses Debian Bug: #468176)
2567 Fix (really minor) bug in debugfs's find_free_block so it avoids
2568 reporting a free block more than once if there are too few free blocks
2569 in the filesystem. (Addresses Sourceforge Bug: #1096315)
2571 Change e2fsck to no longer clear the LARGE_FILES feature flag
2572 automatically, when there are no more > 2GB files in the filesystem.
2573 It's been almost a decade since there have been kernels that don't
2574 support this flag, and e2fsck clears it quietly without telling the
2575 user why the filesystem has been changed.
2577 Fix bug which could cause libblkid to seg fault if a device mapper
2578 volume disappears while it is being probed. (Addresses RedHat
2581 Inhance e2fsck's reporting of unsupported filesystem feature flags.
2582 (Addresses Sourceforge Feature Request: #1175808)
2584 Fix option syntax in dumpe2fs for explicit superblock and blocksize
2585 parameters. What was currently documented in the man page has been
2586 broken for some time, due to getopt() implementation changes. The
2587 option sytax has been changed to one which is can be more portable
2588 supported and which is consistent with the format for extended options
2589 in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
2591 Add support to tune2fs to clear the resize_inode feature. This
2592 requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
2594 Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
2597 Add support for setting RAID stride and stripe-width via mke2fs and
2598 tune2fs. Teach dumpe2fs to print the RAID parameters.
2600 Add support for setting new superblock fields to debugfs's
2603 Add support for printing "mostly-printable" extended attributes in
2606 Add support for the -M option to fsck, which causes it to ignore
2609 Fix uuidd so that it creates the pid file with the correct pid number.
2610 (Addresses Sourceforge Bug: #1893244)
2612 Fix various gcc -Wall warnings.
2614 Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
2616 Fixed spelling mistakes, typos, and otherwise clarified man pages.
2617 (Addresses Sourceforge Patch: #1399325)
2623 Fixed various Debian packaging issues --- see debian/changelog for
2624 details. (Addresses Debian Bug: #466929)
2626 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
2627 partially filled-in filesystem object on an error, so that e2fsck can
2628 print more intelligent error messages.
2630 Add a new function e2p_edit_feature2() which allows the caller to
2631 specify which feature flags are OK to set or clear, and which returns
2632 more specific information about feature flags which are not allowed to
2635 Set the C locale in the test_script driver since it uses [A-Za-z].
2636 (Addresses Sourceforge Bug: #1890526)
2638 Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
2641 Change configure.in to avoid using the 'dc' command unless it is
2642 absolutely needed. (i.e., when using parsing a WIP-style version
2643 number) (Addresses Sourceforge Bug: #1893024)
2645 Add portability checks to support compilation under DJGPP.
2647 Update to the latest samba tdb code before the LGPLv3 change, which
2648 fixes a realloc() leak on failure.
2650 Fix memory leak in ext2fs_alloc_block().
2652 Fix makefile dependency issues for various install targets.
2653 (Addresses-Sourceforge-Patches: #1903484, #1903466, #1903456)
2655 Improve descriptions for the r_move_itable and r_resize_inode tests.
2658 E2fsprogs 1.40.6 (February 9, 2008)
2659 ===================================
2661 Add support for returning labels for UDF filesystems in the blkid
2664 Fix bug in the blkid library where cached filesystems was not being
2665 flushed when opening USB devices returned the error ENOMEDIUM.
2666 (Addresses Debian Bug: #463787)
2668 Added logic to the blkid library to automatically choose whether a
2669 filesystem should be mounted as ext4 or ext4dev, as appropriate.
2671 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
2673 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
2674 configured with --enable-jbd-debug.
2676 Document the BLKID_FILE environment variable in the libblkid man page
2681 Update e2fsprogs translation template and Vietnamese and Czech translations
2683 Fixed various Debian packaging issues --- see debian/changelog for
2684 details. (Addresses Debian Bugs: #436058)
2686 Don't try to create $DESTDIR/etc/init.d as part of make install as we
2687 don't install the init.d script (and it's not the recommended way to
2688 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
2690 Use thread local storage to fix a theoretical race condition if two
2691 threads try to format an unknown error code at the same time in the
2695 E2fsprogs 1.40.5 (January 27, 2008)
2696 ===================================
2698 Fix a potential overflow big in e2image if the device name is too
2701 Mke2fs will now create new filesystems with 256 byte inodes and the
2702 ext_attr feature flag by default. This allows for much better future
2703 compatibity with ext4 and speeds up extended attributes even on ext3
2706 Teach e2fsck to ignore certain "safe" filesystem features which are
2707 set automatically by the kernel. Having the kernel set features
2708 automagically behind the user's back is a bad idea, and we should try
2709 to break the kernel of this habit, especially for the newer ext4
2710 feature flags. But for now, we will try to avoid needless full checks
2711 which can annoy users who are doing fresh installs.
2713 Add support in tune2fs and mke2fs for making a filesystem as being "ok
2714 to be used with test kernel code". This will be needed for using test
2715 filesystems with the latest ext4 kernel code.
2717 Change e2fsck -fD so that it sorts non-htree directories by inode
2718 numbers instead of by name, since that optimizes performances much
2719 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
2721 If e2image fills the disk, fix it so it exits right away instead of
2722 spewing large numbers of error messages.
2723 (Addresses-Sourceforge-Feature-Request: #606508)
2725 If ftruncate64() is not available for resize2fs, let it use ftrucate()
2726 instead, but have it check to see if the size would get truncated, and
2727 skip calling ftruncate in that case.
2729 Add support for detecting HFS+ filesystems in the blkid library.
2731 Add supprt in the blkid library for ext4/ext4dev filesystems.
2733 Fix a bug in blkid where it could die on a floating point exception
2734 when presented with a corrupt reiserfs image.
2736 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
2737 such that UUID string is a fixed length.
2739 Add sample python bindings for the uuid library to the contrib
2740 directory. (Addresses-Sourceforge-Patches: #778817)
2742 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
2743 will work with large files. (Addresses Sourceforge Feature Request:
2744 #1257500 and Sourceforge Support Request: #1253511)
2746 Allow the debugfs 'undel' command to undelete an inode without linking
2747 it to a specific destination directory, since this might require
2748 allocating blocks that could overwrite some yet-to-be-recovered
2749 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
2751 Update Swedish translations from the Translation Project.
2756 Fix configure handling of --sbindir (which should rarely be used, but
2757 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
2760 Updated e2fsprogs.spec file to include a new uuidd package

2763 can find out where it is located on different distributions.
2765 Fix Makefile race so that "make -j3 distclean" works correctly
2767 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
2768 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,

2787 Improve time-based UUID generation. A new daemon uuidd, is started
2788 automatically by libuuid if necessary. This daemon is setuid to allow
2789 updates to /var/lib/libuuid, so the clock sequence number can be
2790 stored and so if the clock is set backwards, it can be detected.
2791 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
2794 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
2795 superblocks. This avoids e2fsck from concluding that a full
2796 filesystem check is required before backing up the superblock due to
2797 changes in the feature flags. (Addresses Debian Bug: #454926)
2799 Fix fsck to only treat the '#' character as a comment at the beginning
2800 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
2801 will cause fsck to issue an bogus warning message.

2840 ===================================
2842 Fix a potential security vulnerability where an untrusted filesystem
2843 can be corrupted in such a way that a program using libext2fs will
2844 allocate a buffer which is far too small. This can lead to either a
2845 crash or potentially a heap-based buffer overflow crash. No known
2846 exploits exist, but main concern is where an untrusted user who
2847 possesses privileged access in a guest Xen environment could corrupt a
2848 filesystem which is then accessed by the pygrub program, running as
2849 root in the dom0 host environment, thus allowing the untrusted user to
2850 gain privileged access in the host OS. Thanks to the McAfee AVERT
2851 Research group for reporting this issue. (Addresses CVE-2007-5497.)
2853 Fix hueristics in blkid which could cause a disk without partitions to
2854 be incorrectly skipped when a loopback device is present. (Addresses
2855 Red Hat Bugzilla #400321.)
2857 Fix e2image so that in raw mode it does not create an image file which
2858 is one byte too large.
2860 Change mke2fs's usage message so it recommends the preferred -E option
2861 instead of the deprecated -R option.
2863 Enhance the blkid library so it will recognize squashfs filesystems.
2864 (Addresses Red Hat Bugzilla #305151.)
2866 Enhance e2fsck so it will force the backup superblocks to be backed up

2871 Enhance blkid's detection of FAT filesystems; so that USB disks with
2872 only a single bootable partition will not get missed.
2874 E2fsck will no longer mark a filesystem as invalid if it has time
2875 errors (i.e., if superblock mount time or last write time is in the
2876 future) and the user refuses to fix the problem.
2878 The Ubuntu init scripts don't properly set the system time correctly
2879 from hardware clock if the hardware clock is configured to tick local
2880 time instead of GMT time. Work around this as best as we can by
2881 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
2882 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
2885 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
2886 Hat Bugzilla #151533.)
2888 Fix e2fsck so that if the superblock is corrupt, but still looks
2889 vaguely like an ext2/3/4 superblock, that it automatically tries to
2890 fall back to the backup superblock, instead of failing with a hard
2893 Make the e2fsprogs program more robust so that they will not crash
2894 when opening a corrupt filesystem where s_inode_size is zero.
2896 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
2897 arguments are detected as such and the parse error is reported to the
2898 user. (Addresses Debian Bug #435381.)
2900 Change e2fsck so it will not complain if a file has blocks reallocated
2901 up to the next multiple of a system's page size.
2903 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
2904 about (valid) filesystems where the inode table extends to the last
2905 block of the block group. (Addresses Red Hat Bugzilla #214765.)
2907 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
2908 allocating inode tables for some relatively rare odd disk sizes.

2932 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
2933 clena up after themselves by deleting the test.img temporary file
2934 after completing the test.
2936 Fixed a corner case bug ext2fs_unlink() when trying to delete the
2937 first directory entry in a directory block and the last directory
2938 entry in the previous directory block is not in use. Fortunately
2939 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
2940 places where it is extremely unlikely to run into this corner case.
2942 Fix missing dependency which would cuase parallel builds to fail.
2943 (Addresses Sourceforge Bug #1842331.)
2945 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
2946 calling open(O_CREATE) with a missing mode parameter.
2948 Fix the test_ss.c in lib/ss so it can be used as an example
2949 application program for the library as well as a regression test
2952 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
2953 are properly passed back up through the call stack.
2955 E2fsprogs 1.40.2 (July 12, 2007)
2956 ================================
2958 A recent change to e2fsck_add_dir_info() to use tdb files to check
2959 filesystems with a very large number of filesystems had a typo which
2960 caused us to resize the wrong data structure. This would cause a
2961 array overrun leading to malloc pointer corruptions and segfaults.
2962 Since we normally can very accurately predict how big the the dirinfo
2963 array needs to be, this bug only got triggered on very badly corrupted
2966 Fix a bug in e2fsck which caused it to incorrectly salvange
2967 directories when the last entry's rec_len is bogusly too big. This
2968 resulted in a nonsense filesystem corruption to be reported, and
2969 required a second run of e2fsck to fully fix up the directory.
2971 Update tune2fs man page to include more discussion of reserved blocks
2972 (Addresses Launchpad bug #47817)
2974 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
2978 E2fsprogs 1.40.1 (July 7, 2007)
2979 ===============================
2981 Fix bug which could cause libblkid to loop forever. When revalidating
2982 a partition where there is obsolete information in /etc/blkid.tab, we
2983 end up freeing a the type tag without clearing dev->bid_type, causing
2984 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
2986 The Turkish translation has a bug in it where it has the translation
2987 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
2988 @E, recursively, forever, until the stack fills up and e2fsck core
2989 dumps. We fix this by making e2fsck stop @-expansions after a
2990 recursive depth of 10, which is far more than we need.
2991 (Addresses Sourceforge Bug: #1646081)
2993 Compile the default mke2fs.conf into mke2fs program. People are
2994 getting surprised by mke2fs creating filesystems with different
2995 defaults than earlier versions of mke2fs if mke2fs.conf is not
2996 present. So we now create a built in version of mke2fs.conf file
2997 which is used by mke2fs if the /etc/mke2fs.conf is not present.
2998 (Addresses SourceforgeBug: #1745818)
3000 Improve the config/parse_types.sh helper script. Fix a potential
3001 security problem if e2fsprogs is built as root (as Gentoo does!). In
3002 addition fix the script and how it is called from the configure script
3003 so that it does the right thing when cross-compiling. (Fixes Gentoo
3006 Update Vietnamese, French, and Dutch PO files from the Translation
3007 Project. Also created a new e2fsprogs.pot file for translator.
3009 Fix bogus strip permission errors when building under Debian. When
3010 building the e2fsprogs dpkg's, the dh_strip command emits a large
3011 number of error messages caused by the permissions not being right.
3012 So run dh_fixperms before running dh_strip.
3017 Add new function: profile_set_default(). This function sets the value
3018 of the pseudo file "<default>". If the file "<default>" had
3019 previously been passed to profile_init(), then def_string parameter
3020 will be parsed and used as the profile information for the "<default>"
3023 Fix mk_cmds's error reporting so that it is unambiguous that it is the
3024 mk_cmds script which is generating the error. (Obviates Gentoo patch:
3025 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
3027 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
3028 priority" environment variable that overrides all others, where as
3029 LANG is the lowest priorty environment variable. If LC_ALL is set, it
3030 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3031 the all the rest are set. This will assure that the locale when
3032 running the test suites is the "C" locale. (Obviates Gentoo patch:
3033 e2fsprogs-1.38-tests-locale.patch)
3036 E2fsprogs 1.40 (June 29, 2007)
3037 ==============================
3039 Fix divide by zero error in blkid's NTFS probing logic.
3041 Add new blkid -g option which causes the blkid cache to be garbage
3044 Fix a bug in libblkid which could cause the internal field bid_type to
3045 become corrupted. Fortunately bid_type isn't used much, and bid_label
3046 and bid_uuid is only used by debugging code, so the impact of this bug
3049 Mke2fs will now store the RAID stride value when a filesystem is
3050 created with a requested RAID stride, and then use it automatically in
3053 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3054 isn't too big. In some cases Lustre users have tried specifying an
3055 inode size of 4096 bytes, while keeping an inode ratio of one inode
3058 Improve sanity check in e2fsck's algorithm for finding a backup
3059 superblock, so that it won't accidentally find a superblock that was
3060 located in the journal, and then later reject it as being not a valid
3063 Fix e2fsck get_size logic so that it will work with the Linux floppy
3064 driver. The Linux floppy driver is a bit different from the other
3065 block device drivers, in that if the device has been opened with
3066 O_EXCL, it disallows another open(), even if the second open() does
3067 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
3069 Fix error checking of badblock's last-block and start-block arguments.
3070 (Addresses Debian Bug: #416477)
3072 Fix e2fsck so that it doesn't overwrite the backup superblocks when
3073 recovering a journal until the master superblock has been confirmed as
3076 Change the blkid library to be much more paranoid about concluding
3077 that a partition contains an NTFS filesystem, and fetch the UUID and
3078 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
3081 Factor out the code which sets the default journal size and move it
3084 Enhance e2fsck so it will recreate the ext3 journal if the original
3085 journal inode was cleared to due it being corrupt after finishing the
3088 Fix e2fsck so that it updates the journal inode if it is corrupted and
3089 the backup journal information from the superblock was successfully
3090 used to recover the filesystem.
3092 Fix e2fsck so that it checks all of the blocks in the journal inode
3093 for validity. The original code only checked the direct blocks to
3094 make sure the journal inode was sane. Unfortunately, if some or all
3095 of the indirect or doubly indirect blocks were corrupted, this would
3098 Add support in blkid to detect LUKS encrypted partitions.
3100 Add extra sanity checks for extended attributes in the case where the
3101 size is zero but the offset is very large.
3103 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3104 and ext2fs_get_next_inode_full().
3106 Clarify the copyright licenses used by the various libraries in
3107 the top-level COPYING file (Red Hat Bugzilla: 166058)
3109 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3111 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3113 Remove check in e2fsck which requires EA's in inodes to be sorted;
3114 they don't need to be sorted, and e2fsck was previously wrongly
3115 clearing unsorted EA's stored in the inode structure.
3117 Allow mke2fs or tune2fs to create a substantially larger journal (up
3118 to 10,240,000 blocks).
3120 Fix MD superblock detection, and make sure the correct UUID is
3121 reported from the MD superblock.
3123 Fix a signed vs. unsigned bug in debugfs.
3125 Enhance debugfs's date parser so that it accepts integer values.
3127 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
3128 file with multiply claimed blocks is hard linked. or not at all if the
3129 root directory contains shared blocks
3131 Enhance debugfs so it can modify the block group descriptors using the
3132 command set_block_group_descriptor.
3134 Improve e2fsck's reporting of I/O errors so it's clearer what it was
3135 trying to do when an error happens
3137 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
3138 symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
3139 #232663 and LTC Bugzilla: #27634)
3141 Fix potential file descriptor leak in ext2fs_get_device_size() in an
3144 Add libreadline.so.5 support to libss.
3146 Impove badblocks -n/-w exclusive usage message.
3148 Fix dump_unused segfault in debugfs when a filesystem is not open
3150 Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
3152 Allow the debugfs lcd command to work w/o a filesystem being open.
3153 (Addresses LTC Bugzilla #27513)
3155 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
3156 field on the first pass.
3158 Fix e2fsck to set the file type of the '..' entry when connecting
3159 a directory to lost+found. (Addresses Lustre Bug: #11645)
3161 Enhance e2fsck to recover directories whose modes field were corrupted
3162 to look like special files. This is probably only useful in
3163 artificial test cases, but it will be useful if we ever do the "inodes
3164 in directory" idea for ext4.
3166 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
3169 Fix resize2fs parsing of size parameter (in sector units). This was
3170 actually a bug in libe2p's parse_num_blocks() function. When handling
3171 the 's' suffix, it was ignoring the blocksize information passed in
3172 from the caller and always interpreting the number in terms of a 1k
3173 blocksize. (Addresses Debian Bug: #408298)
3175 There was a floating point precision error which could cause e2fsck to
3176 loop forever on really big filesystems with a large inode count.
3177 (Addresses Debian Bug: #411838)
3179 Fix memory leak in ext2fs_write_new_inode()
3181 Add support for using a scratch files directory to reduce e2fsck's
3182 memory utilization on really big filesystems. This uses the TDB
3183 library. See the [scratch_files] section of the e2fsck.conf man page
3186 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
3187 platform (Addresses Debian Bug: #397044)
3189 Add explanatory message to badblocks that -n and -w are mutually exclusive
3190 (Addresses Debian Bug: #371869)
3192 Allow debugfs and dumpe2fs to support fs features under development.
3194 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
3195 ext2fs_open() , which allows application to open filesystes with features
3196 which are currently only partially supported by e2fsprogs.
3198 Allow unix_io to support offsets greater than 2G (Addresses
3199 SourceForge Bug: #1547922)
3201 Fixed overflow and signed/unsigned problems caused by the number of
3202 blocks or inodes exceeding 2**31 or being close to 2**32-1.
3204 Add support for unsigned directory hash calculations with hints in the
3205 superblock to fix cross-architectural portability for htree
3206 directories with filenames where the high 8th bit is set. (Addresses
3209 Fix resize2fs so that it gives user-intelligible error messages if the
3210 filesystem or the kernel does not support on-line resizing.

3213 Require mke2fs -F -F for really dangerous operations, since -F is
3214 needed for less dangerous operations such as creating filesystems
3215 images in regular files, or creating filesystems on whole block
3216 devices. These relatively innocuous usages should NOT be confused
3217 with running mke2fs on an apparently-mounted or in-use filesystem.
3219 Allow the default inode size to be specified into the mke2fs.conf
3222 Make the smallest default journal size is big enough so that on-line
3223 resizing should always work.
3225 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
3228 Fix debugfs coredump when lsdel is run without an open filesystem
3229 (Addresses Debian Bug: #378335)
3231 Fix debugfs display bug us that bytes that have the high bit set are
3232 displayed as "ec" instead of "ffffffec".
3234 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
3236 Device mapper scanning wasn't working in the blkid library because the
3237 pathnames had an extra "/dev" when they were being probed.
3239 Add GFS/GFS2 support to the blkid library.
3241 Fix blkid support of empty FAT filesystem labels.
3243 Avoid recursing forever (or for a long time) when the blkid library
3244 searches for a device and there are symlinks to directories in /dev.
3246 Avoid unaligned halfword access in blkid when accessing FAT
3247 superblocks, as this will cause Sparc/Solaris systems to throw a

3254 Improve the (non-installed, for experts only) findsuper program by
3255 printing the uuid and label from the superblocks, as well as the
3256 starting and ending offsets of the filesystem given the information in
3257 the superblock. Omit by default printing superblocks that are likely
3258 found in located in an ext3 journal unless an explicit -j option is
3261 Updated Spanish, French and Dutch translations and added Catalan
3262 translation. (Addresses Debian bug: #411562)
3264 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
3265 determining a partition's size, since binary searching to determine
3266 the device doesn't work on FreeBSD.
3268 Documentation about UUID's is available in enough places, and it's
3269 awkward to deal with debian-legal's insanities. So I'm caving in the
3270 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
3271 don't have do the dfsg tarball. Also remove the rule that only tried
3272 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
3273 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
3275 Fix the info-dir line so that the menu name does not contain a .info
3276 prefix. First of all, it's ugly, secondly, it causes the install-info
3277 command to fail to remove the com_err info file from the
3278 /usr/share/info/dir file when the comerr-dev package is removed and
3279 purged. (Addresses Debian Bug: #401711)

3292 E2fsck now supports the %It expansion when printing a problem report.
3293 It will print the type of the inode in the problem context.

3296 (Addresses Sourceforge Bug: #1565561)
3298 Remove unused variables and other lint/gcc -Wall cleanups
3300 Add check to ext2fs_get_device_size() so it will return EFBIG for for
3301 filesystems contained in regular files where the filesystem image size
3302 is returned by stat64().
3304 Set local environment variables to C so mk_cmds and compile_et always
3305 work. (Addresses SourceForge Bug: #1532177)
3307 Added the 64-bit byte swapping function ext2fs_swab64().
3309 Added two new helper functions to prevent 2**31/2**32-1 overflow
3310 problems: ext2fs_div_ceil() and e2p_percent().
3312 Create new ext2fs library inline functions ext2fs_group_first_block()
3313 and ext2fs_group_last_block() in order to calculate the starting and
3314 ending blocks in a block group.
3316 Create the generated files read-only to remind developers not to edit them.
3318 Add support for autoconf 2.60 (with backwards compatibility for older
3319 versions of autoconf).
3321 Added an "make rpm" target to top-level Makefile
3323 Added various FreeBSD portability fixes.
3325 Exclude mercurial files from the RPM build tree to speed up copy/build.
3327 Use root_sysconfdir to define the locations of mke2fs.conf and
3328 e2fsck.conf instead of using a hard-coded /etc pathname.
3330 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
3332 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
3334 If diff -u is supported, use it to report test failures.
3336 Updates/improvements to RPM spec file
3338 Add on-disk format definitions for the following new features:
3339 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
3340 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
3341 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
3343 Add a new make target "checked-failed" in the tests directory which
3344 reruns any failed tests
3346 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
3348 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
3349 pointer dereferences, memory leaks, etc. None were security-criticial
3352 Fix up usage and decrement error messages in the test_icount program
3354 Add debugging code to the com_err library; if the environment variable
3355 COMERR_DEBUG is set to 1, print out debugging messages as error tables
3356 are added and removed from the com_err library. If the
3357 COMERR_DEBUG_FILE environment variable is set (and the process is not
3358 setuid) the debugging messages may be redirected to a file.
3360 Change all of the e2fsprogs programs to use the newer add_error_table()
3361 and remove_error_table() interfaces instead of the much older
3362 initialize_*_error_table() function.
3364 Add TDB support into the ext2fs library. This allows us to have a
3365 guaranteed library we can count on always being present so we can
3366 store data in an on-disk database.
3368 Add support for using TDB to store the icount data, so we don't run out
3369 of memory when checking really large filesystems.
3371 Change the regression test suite so that it skips empty test directories.
3373 Define the l_i_iversion field in ext2_inode. The l_i_version field is
3374 now defined from the old l_i_reserved1 field in the ext2 inode. This
3375 field will be used to store high 32 bits of the 64-bit inode version
3378 Add Makefile production rule for e2fsprogs.spec in case it gets
3381 Add new function profile_get_uint() to allow for a clean way to fetch
3382 unsigned integers from the context.
3384 Add test to make sure the ext2 superblock structure is 1024 bytes.
3386 Fix typo in name of f_dup4 regression test
3388 Add new function blkid_gc_cache() which performs a garbage collection
3389 pass on the /etc/blkid.tab file.
3391 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
3392 general, only e2fsck (after the filesystem is clean), tune2fs, and
3393 resize2fs should change the backup superblocks by default. Most
3394 callers of ext2fs_open() should not be touching any superblock fields
3395 which require the backups to be touched.
3397 Add new function to libext2fs, ext2fs_default_journal_size(), which
3398 returns the default journal size.
3401 E2fsprogs 1.39 (May 29, 2006)
3402 =============================
3404 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
3405 between 2**31 and 2**32 blocks.
3407 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
3408 configure the filesystem features, blocksize, and inode_ratio for
3409 different filesystem types.
3411 Mke2fs will now create filesystems hash trees and on-line resizing
3412 enabled by default, based on the new /etc/mke2fs.conf file.
3414 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
3415 filesystem device node in exclusive mode to prevent accidents by
3416 system administrators. In the case of resize2fs and mke2fs, it will
3417 only use exclusive mode if the filesystem is not mounted.
3419 Fixed a bug in mke2fs which caused it to to fail when creating the
3420 resize inode for large filesystems. (Addresses Debian Bug #346580)
3422 When allocating space for the RAID filesystems with the stride
3423 parameter, mke2fs will now place each portion of the group's inode
3424 table right up after the superblock (if present) in order to minimize
3425 fragmentation of the freespace.
3427 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
3428 efficiently by writing the inode and block bitmaps in one pass, thus
3429 reducing the number of disk seeks required.
3431 Add support for on-line resizing to resize2fs.
3433 Fix blkid library so that logic to determine whether or not a device's
3434 cached information in /etc/blkid.tab needs to be verified or not
3435 doesn't get confused by a system clock which is insane (for example,
3436 if the battery is dead on a Macintosh running PPC Linux. (Addresses
3437 Red Hat Bug: #182188)
3439 The blkid library will now store the UUID of the external journal used
3440 by ext3 filesystems, so that in the future, the userspace mount binary
3441 can use this to find the location of the external journal and pass
3442 this information to the kernel.
3444 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
3445 control how various options should be handled. See the e2fsck.conf
3446 man page for more details. (Addresses Debian Bug: #150295)
3448 E2fsck now prints an explanatory message when delaying a filesystem
3449 check when the system is running on battery. (Addresses Debian Bug:
3452 E2fsck will detect if the superblock's last mount field or last write
3453 field is in the future, and offer to fix if so. (Addresses Debian Bug
3454 #327580) These problems will be fixed automatically in preen mode
3455 since Debian's boot sequence bogusly doesn't set the time correctly
3456 until potentially very late in the bootup process, and this can cause
3457 false positives which will cause users' systems to fail to boot.
3458 (Addresses Debian Bugs #343662 and #343645)
3460 E2fsck now checks to see if the superblock hint for the location of
3461 the external journal is incorrect, and if so, offer to update it.
3462 (Addresses Debian Bug: #355644)
3464 Fix e2fsck from segfaulting on disconnected inodes that contain one or
3465 more extended attributes. (Addresses Debian Bug: #316736, #318463)
3467 E2fsck will stop and print a warning if the user tries running a
3468 read/write badblocks test on a read-only mounted root filesystem.
3470 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
3471 C. Thompson for pointing these out; they were originally found using
3474 When resizing a file containing a filesystem, resize2fs will expand or
3475 truncate a file as necessary. (Addresses Debian Bug: #271607)
3477 Resize2fs will now automatically determine the RAID stride parameter that
3478 had been used to create the filesystem, and use that for newly created
3479 block groups. The RAID stride parameter may also be manually specified
3480 on the command line using the new -S option to resize2fs.
3482 Fix mke2fs so that it correctly creates external journals on
3483 big-endian machines (such as a S/390).
3485 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
3486 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
3487 Chambraud for pointing this out.)
3489 Dumpe2fs will now print the size of the journal (if present).
3491 Fix debugfs's set_inode_field command so it can properly set the frag,
3492 fsize, uid_high, gid_high, and author fields in the inode instead of
3493 silently failing, and so that setting the i_size actually sets i_size
3496 Add a new debugfs command, set_current_time, which sets fs->now so
3497 that regression test suites can repeatedly modify the filesystem's
3500 Fix a bug in debugfs's icheck which would incorrectly report the owner
3501 of an extended attribute block.
3503 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a

3506 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
3507 so it won't core dump. (Addresses SourceForge bug #1424311)
3509 Fix mklost+found so that it creates a full-sized directory on
3510 filesystems with larger block sizes.
3512 Fix a file descriptor leak in blkid library.
3514 Fix a display bug in "badblocks -sv" so that the done message properly
3515 clears the block number at the end of the test. (Addresses Debian Bug
3518 Allow fractional percentages to the -m option in mke2fs and tune2fs

3526 that the "best" (i.e., leaf) device is probed by the blkid library.
3528 Fix the blkid library so that it notices when an ext2 filesystem is
3531 Improve the blkid's library VFAT/FAT detection; it now understands
3532 labels stored in the root directory, and is more paranoid about
3533 checking the FAT superblock values.
3535 Fixed a fd leak in the uuid library which was causing problems for the
3536 LVM tools. (Addresses Debian Bug: #345832)
3538 Add support for the reiser4 and software suspend partitions to the
3539 blkid library. Also add support for extract the label from iso9660
3542 Fix a compile_et bug which miscount the number of error messages if
3543 continuations are used in the .et file.
3545 Add extra sanity checks to protect users from unusual cirucmstances
3546 where /etc/mtab may not be sane, by checking to see if the device is
3547 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
3550 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian

3553 Fix use-after-free bug in e2fsck when finishing up the use of the
3554 e2fsck context structure.

3574 Bugs: #360661, #360317)
3576 Fixed the Makefile so that they work correctly on newer versions of
3577 GNU make (i.e., 3.81).
3579 Add valgrind support to the regression test suites, and eliminate
3580 false positives from valgrind.
3582 Add a regression test suite for the blkid library.
3584 Fix a fencepost error in resize2fs caught by valgrind.
3586 Fix compiler warnings about missing memcpy prototypes.
3588 We no longer have the sparc assembly code in the header file any more,
3589 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
3590 break compiles on the sparc architectures when using gcc.
3592 In the libext2fs library, add the new field fs->now which if non-zero
3593 is used instead of the system time when setting various filesystem
3594 fields (last modified time, last write time, etc.)
3596 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
3597 ext2fs.h which is needed since the inline functions use memcpy().
3598 (Addresses Sourceforge Bug #1251062)
3600 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
3601 the build system when building files in the util directory which are
3602 needed during the build process. This avoids potential problems when
3603 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
3604 are not recognized as valid by the host compiler. (Addresses
3605 Sourceforge Bug #1261547)
3607 Clean up the blkid library by making the superblock and generic i/o
3608 functions to be more generic. Clean up interface to the probe
3609 function, and fix memory leak. Finallly, remove an unneeded reference
3610 to probe.h in the lib/blkid/resolve.c
3612 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
3613 of invalid block #'s.
3615 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
3616 indicate that the the function read/writes the memory location.
3618 Fix various gcc -Wall complaints.
3620 Add a dependency to make sure that the subdirectories are created
3621 before creating all of the object files, in order to address parallel
3622 build problem in the library Makefiles. (Addresses Sourceforge Bug:
3625 Add $(LDFLAGS) to the command line argument when generating an ELF or
3626 Solaris shared library, to allow cross-compile and other builds that
3627 might need to specify -L paths to needed libraries. (Addresses
3628 Sourceforge Bug #1261549)
3630 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
3631 intended for testing purposes. It allows an ext2/ext3 developer to
3632 create very large filesystems using sparse files where most of the
3633 block groups are not initialized and so do not require much disk
3634 space. Eventually it could be used as a way of speeding up mke2fs and
3635 e2fsck for large filesystem, but that would be best done by adding an
3636 RO_COMPAT extension to the filesystem to allow the inode table to be
3637 lazily initialized on a per-block basis, instead of being entirely
3638 initialized or entirely unused on a per-blockgroup basis.
3640 Fix backwards compatibility so e2fsprogs will better compile on Linux
3643 Make test scripts more robust against locale-related environment variables
3645 Fix type warning problem with sizeof() in ext2fs_open2().
3647 Fix type warning problem with time_t in debugfs.

3651 ==============================
3653 Fix blkid's test programs (built with "make check") compile correctly
3654 even without "configure --enable-blkid-debug".
3656 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
3657 type aliasing rules on newer gcc compilers. (Addresses Red Hat
3660 Fix com_err library to make it more compatible with recent changes
3661 made to the com_err library in MIT Kerberos V5 version 1.4.
3662 (Addresses Sourcefroge Bug #1150146)
3664 General cleanup of messages printed by e2fsprogs programs for grammar,
3665 consistency, and to make life easier for translators. Fixed a few
3666 strings containing English that had not been marked as needing
3667 translations. Removed strings that do not need to be translated, to
3668 make life easier for translators.
3670 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
3671 test to see if a device appears to be in use instead of just relying
3672 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
3674 Fix portability problem in the filefrag program affecting platforms
3675 where the size of an integer is smaller than the size of a long.
3676 (Addresses Debian Bug #309655)
3678 Mke2fs will now use a larger journal by default for filesystems
3679 greater than 4GB. (128 MB instead of 32MB).
3681 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
3682 unless forced. This is to avoid signed vs. unsigned kernel bugs in
3683 block numbers that still need to be fixed.
3685 The blkid program has a new option which will more efficiently search
3686 for device when it is known (or expected) that only one matching
3687 device will be found in the system, such as when doing a lookup by
3690 Debian's e2fsprogs-specific initrd fragment will avoid including
3691 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
3692 and LD_LIBRARY_PATH, and filtering out libraries found in
3693 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
3695 Fixed a potential portability issue in the blkid programs for
3696 architectures where the char type is unsigned. (Addresses Sourceforge
3699 Fix a bug in filefrag so that it doesn't falsely count an extra
3700 discontinuity when the first block found is an indirect block.

3704 able to handle cramfs labels.
3706 Fix debugfs's stat command to not core dump when a filesystem is not

3714 Fixed bug in filefrag which caused it to fail on non-ext2/3
3715 filesystems. (Addresses Debian Bug: #303509)
3717 If the superblock last mount time indicates that the system clock may
3718 not be accurate, then e2fsck will omit checking inodes' deletion time
3719 field for indications of a potential corrupted orphaned inode list.
3720 (Previously e2fsck only ommited these LOW_DTIME checks when the
3721 superblock's last write time looked insane.)
3723 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.

3726 Make the blkid library more paranoid about being run from setgid
3727 programs, and to use __secure_getenv() from libc if it is available.

3733 Updated and fixed translations.
3735 Fixed various Debian packaging issues --- see debian/changelog for
3741 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
3742 changed to take an unsigned int for the bit number. Negative bit
3743 numbers were never allowed (and didn't make any sense), so this should
3744 be a safe change. This is needed to allow safe use of block numbers
3745 greater than or equal to 2**31.
3747 The compile_et program will avoid recreating generated foo_err.c and
3748 foo_err.h files if no changes are necessary. The compile_et program
3749 will also atomically replace these files to avoid a potential parallel
3750 build race problem on SMP systems. (Addresses Sourceforge Bug:
3753 Added a new function to the blkid library, blkid_probe_all_new(),
3754 which only probes newly added disk devices, and change
3755 blkid_find_dev_with_tag() to use this function so that when a
3756 requested tag is not found, devices that were previously not checked
3757 are searched before searching all devices in the system.
3759 Added new functions to the blkid library, blkid_dev_set_search() and
3760 blkid_dev_has_tag().
3762 E2fsck's problem strings can now use @m and @n as abbrevations for
3763 "multiply-claimed" and "invalid", respectively.
3765 The e2fsprog.pot file now has an explanation of how the @-expansion
3766 and %-expansion works, and strings in e2fsck/problem.c which contain @
3767 characters now have comments in e2fsprogs.pot with the @-expansion to
3768 make life easier for translators.
3770 Fixed missing return values in the ext2fs library which could cause it
3771 to return random garbage in certain error conditions.
3773 Allow the current time to be overriden via the E2FSCK_TIME environment
3774 variable for use in regression tests.
3776 The test scrpit driver program now exits with a non-zero status if
3777 there any of its test that it ran failed.
3779 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge

3786 Fixed gcc -Wall nits.
3789 E2fsprogs 1.37 (March 21, 2005)
3790 ===============================
3792 Add support for checking the validity of Extended Attributes stored in
3795 Add support for dumping the contents of large inodes to debugfs,
3796 including the extended attributes stored in inodes.
3798 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
3799 when we create a new inode we make sure that the extra information in
3800 the inode (any extra fields in a large inode and any ea-in-inode
3801 information) is initialized correctly. This can take place when
3802 mke2fs creates the root and lost+found directory, when e2fsck creates
3803 a new root inode or a new lost+found directory, and when the user uses
3804 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
3805 create inode could inherit garbage (or old EA information) from a
3806 previously deleted inode.
3808 Fixed a bug in e2fsck so it would notice if a file with an extended
3809 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
3812 Added support to filefrag to detect files which are using the new
3813 experimental file extents format, and use the non-ext2 algorithm in
3814 that case. Fixed a bug to avoid reporting a false discontinuity if
3815 there is one or more unallocated blocks at the beginning of a file.
3817 Duplicated a check for noticing whether or not the number of blocks
3818 (given a certain blocksize) is greater than 2**32 when the
3819 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
3820 allows mke2fs to automatically use a larger blocksize when creating a
3821 filesystem on a very large device when run on systems that do not
3822 support BLKGETSIZE64.
3824 Fix the I18N build which was broken in e2fsprogs 1.36 because the
3825 build system had been switched to treat the .gmo files as shipped
3826 files (for backwards compatibility with systems that have older GNU
3827 I18N tools installed), but the gen_tarball.in script was still
3828 removing the .gmo files from the official source distribution.
3830 Fixed various Debian packaging issues --- see debian/changelog for
3831 details. (Addresses Debian Bugs ##296769, #299341)
3836 Added new functions to the e2p library which convert between a string
3837 and os_type: e2p_os2string() and e2p_string2os(), and used them to
3838 make the generated binaries more compact.
3840 Fixed a compile-time error on Darwin systems.
3842 Cleaned up the lib/ext2fs Makefile slightly.
3845 E2fsprogs 1.36 (February 4, 2005)
3846 =================================
3848 All of the patches that were applied to Fedore Core 3's
3849 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
3850 lot of bug fixes first. Users of Fedora Core 3 are strongly
3851 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
3853 Add support for filesystem with the online resizing via resize inode
3854 feature. Fixed numerous bugs from the Fedora patches. The Fedora
3855 patches also didn't bother to do any consistency checking on the
3856 resize inode, or add any tests to the regression test suite. The "-R
3857 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
3858 being listed in mke2fs's usage message. All of these shortcomings
3859 have been corrected.
3861 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
3862 program. In order to do this, the user must run the commands:
3864 debugfs -w /dev/hdXXX -R "features ^resize_inode"
3865 e2fsck -f /dev/hdXXX
3867 Optionally, the ext2prepare command can be used to re-enable online
3868 resizing after the filesystem has been fixed.
3870 The fsck program will now accept an optional filedescriptor argument
3871 to the -C option. (The Fedora version of this patch would sometimes
3872 cause fsck to ignore a parameter on fsck's command line in some rare
3875 Make sure e2fsprogs doesn't write garbage into the reserved portion of
3878 Make sure resize2fs releases the blocks belonging to the old inode
3879 table blocks when moving the inode table. (Addresses Debian Bug:
3882 Skip the r_resize_inode test if resize2fs is not compiled (due to
3883 configure --disable-resizer)
3885 E2fsck now checks the summary filesystem accounting information, and
3886 if any of the information is obviously wrong, it will force a full
3887 filesystem check. (Addresses Debian Bug #291571)
3889 Fix e2fsck to not complain when the resize_inode feature is enabled,
3890 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
3893 Fix e2fsck to note delete symlinks that contain an extended attribute
3894 after the ext_attr feature flag has been cleared. (Addresses Red Hat
3897 Add new utility program, copy_sparse.c, which is very useful
3898 for dealing with large sparse files (such as e2image files).
3900 Add support for jnl_blocks[] for debugfs's set_super_value.
3902 Fix filefrag so that it works correctly with sparse files.
3904 Filefrag -v will print first and last blocks.
3906 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
3909 Add mke2fs support so that it can support filesystems larger than 4TB
3910 automatically, by retrying with a 4k blocksize if the device size is
3911 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
3914 Change blkid to test for NTFS first because Windows sometimes doesn't
3915 clear enough of the parition to confuse the probing routines into
3916 thinking the old filesystem type is still valid. (Addresses Debian
3919 Add support for swap partition label and uuid's in the blkid library.
3921 Add support to the blkid library to recognize Oracle ASM volumes.
3923 Make blkid -t display all devices that match the specified criteria,
3924 not just the first one, and work more consistently when the blkid
3925 cache file is not available or set to /dev/null. (Addresses Debian
3926 Bug #290530 and #292425)
3928 Badblocks will now correctly display block numbers greater than
3929 999,999,999 in its progress display.
3931 The tune2fs program will not allow the user from setting a ridiculous
3932 number of reserved blocks which would cause e2fsck to assume the
3933 superblock was corrupt. E2fsck's standards for what is a ridiculous
3934 number of reserved block has also been relaxed to 50% of the blocks in
3937 The blkid library will return vfat in preference to msdos, and ext3 in
3938 preference to ext2 (if the journalling flag is set) so that mount will
3939 do the right thing. (Addresses Debian bug #287455)
3941 Mke2fs will now use the -E option for extended options; the old -R
3942 (raid options) option is still accepted for backwards compatibility.
3943 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
3945 Mke2fs will now accept a size in megabytes, gigabytes, and other units
3946 (via "32m" or "4g" on the command line) if the user finds this more
3947 convenient than specifying a block count.
3949 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
3950 cache conherency problem.
3952 Debugfs now supports a new command, set_inode_field, which allows a
3953 user to manually set a specific inode field more conveniently, as well
3954 as set entries in the indirect block map.
3956 Debugfs's set_super_value command has been enhanced so that the user
3957 can set most superblock fields, including the date/time fields and
3958 some of the more newsly added superblock fields.
3960 E2fsprogs programs now accept an offset to be passed to the file
3961 specifiers, via the syntax: "/tmp/test.img?offset=1024".
3963 E2fsprogs programs will now accept blocksizes up to 65536; kernel
3964 support on the x86 doesn't exist for now, but it can be useful on
3965 other architectures with page sizes greater than 4k. There are 2.6
3966 kernel patches out there which enable this, but they are of this
3967 writing still experimental.
3969 The e2image command now takes the -s option which will scramble
3970 directory entries for raw image files.
3972 Fix a file descriptor leak in the filefrag program.
3974 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
3977 Fix bug in debugfs where kill_file would lead to errors when deleting
3978 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
3980 Fix bug in the blkid library when detecting the ocfs1 filesystem
3982 Remove obsolete EVMS 1.x and a.out DLL support.
3984 E2fsck will attempt to recover from a journal containing illegal blocks.
3986 Fixed two potential ordering constraint problems in e2fsck which might
3987 cause the filesystem to be corrupted if e2fsck is interrupted during a
3988 (extremely narrow) race window. Thanks to Junfeng Yang from the
3989 Stanford Metacompilation group for pointing this out.
3991 Fixed bug in e2fsck where it would not accurately detect whether or
3992 not the system is running on adaptor if the ACPI device representing
3993 the AC adapter didn't correspond to the what was used on IBM
3996 Change e2fsck to accept directories greater than 32MB.
3998 Fix e2fsck so that a checkinterval of zero disables a time-based check
4001 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4002 to the PAGER environment variable. (Addresses Debian Bug #239547)
4004 Tune2fs will not mark rewrite the superblock if the feature bitmasks
4007 The debugfs program will set the filetype information when creating a
4010 Add debugfs -d option to use a separate source of data blocks when
4011 reading from an e2image file.
4013 Add e2image -I option which allows the e2image metadata to be
4014 installed into a filesystem.
4016 Fixed bug in the badblocks program which caused "done" to always
4017 appear in english even when a translation was available. (Addresses
4020 The blkid program has a new option -o which controls the output format
4021 of the blkid program; this is makes blkid more convenient to use in
4024 Fix a minor bug in uuid library, which was not using the full 14 bits
4025 of clock sequence when generating UUID's.
4027 Fix a Y8.8888K problem in the uuid library.
4029 Logsave now creates a new session id for itself to avoid getting
4030 killed by init whan transitioning between init levels.
4032 Change the licensing of the UUID library to be the 3-clause BSD-style
4033 license; this allows Apple to use the uuid library in Darwin.
4035 Add ocfs and ocfs2 probe support into the blkid library.
4037 Fix a memory and file descriptor leak in the blkid library.
4039 The blkid library will revalidate the device if the system time is
4040 earlier than last verification time of the device, since that
4041 indicates that the system time is probably nottrustworthy.
4043 The blkid library will override the default location of the blkid.tab
4044 file by the BLKID_FILE environment variable, if it is available.
4046 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4048 Add various portability fixes for lame new versions of glibc, Darwin
4049 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
4050 Bugs #239934, #264630, #269044, #255589, #289133)

4057 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
4059 Update the rpm spec files so that it works better with Fedora core 2
4062 Fixed various Debian packaging issues (see debian/changelog). In
4063 particular, fixed the Debian initrd scripts. (#241183, #248050,
4070 Fixed various gcc -Wall warnings.
4072 The uuid library now has new functions uuid_unparse_upper() and
4073 uuid_unparse_lower() which forces the case of the hex digits to be
4074 upper case, or lower case.
4076 The build process has been speeded up by enhancing the subst program
4077 to update the modtime on the generated files even when the generated
4078 file hasn't changed.
4080 The uuid library now uses C99 stdint.h types instead of custom types.
4082 Updated config.guess and config.sub with newer versions from the FSF.
4084 Removed out of date .cvsignore files from the source distribution.
4086 The ext2fs_unlink() function will return an error if both the name and
4087 inode number are unspecified, to avoid doing something surprising
4088 (such as unconditionally deleting the first directory entry).
4089 Directory entries are now deleted by coalescing them with the previous
4090 directory entry if possible, to avoid directory fragmentation. This
4091 is not an issue with the e2fsprogs suite, but may be a problem for
4092 some of the users of libext2fs, such as e2tools.
4094 Add support for version numbers of the form "1.36-rc1".
4096 Fix build of mke2fs.static.
4098 Add basic ext2fs library support for large (EA in inode) inodes.
4100 The test_io mechanism can now abort after n reads or writes to a
4101 particular block. The block is specified by TEST_IO_BLOCK environment
4102 variable, and the read/write count by the TEST_IO_READ_ABORT and
4103 TEST_IO_WRITE_ABORT environment variables. The block data is now only
4104 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4106 UUID_DEFINE() in the uuid library now creates a static variable, with
4107 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4108 be used in header files.
4110 Add support for the install-strip and install-shlibs-strip targets, as
4111 suggested by the GNU coding guielines. "make install" no longer
4112 strips the binaries which are installed.
4114 Remove support for the --enable-old-bitops configure option which was
4115 only for very old sparc systems.
4117 Remove support for --enable-clear-htree; this was only needed during
4118 the early development of the htree patch.
4120 Use Linux-kernel-style makefile output so it is easier to see compiler
4123 Update gettext files to version 0.14.1.
4125 Update to use autoconf 2.5x.
4127 Improved support for compiling e2fsprogs under dietlibc.
4129 Make e2fsprogs portable to Solaris and FreeBSD systems.
4131 Add blkid_verify(), blkid_get_library_version(), and
4132 blkid_parse_version_string() functions to the blkid library.
4134 Add pkg-config files for e2fsprogs's libraries.
4136 Fix "make uninstall" to so that it removes everything that is installed.
4138 Add a configure --enable-maintainer-mode option which enables the
4139 makefile rules to rebuild the configure script from configure.in, and
4140 to reubuild the .gmo files in po directory.
4142 Drop the sparc assembly bitwise operations; it's less efficient
4143 than the GCC 3.4 compile code and triggers compiler warnings on
4144 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
4145 (Addresses Debian Bug #232326)
4148 E2fsprogs 1.35 (February 28, 2004)
4149 ==================================
4151 E2fsck has a new -k option, which in conjunction with the -c options,
4152 preserves the existing badblocks list.
4154 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
4156 E2fsprogs will now deal correctly with symlinks that contain
4157 extended attribute information, which can be created using SE Linux.
4158 (Addresses Debian Bug #232328)
4160 Remove a double longjump into an invalid stack frame bug in e2fsck.
4161 (This was during an abort sequence, which normally worked on Linux and
4162 caused a core dump on other operating systems.)
4164 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
4165 (the NLS library will replace "" with the .po header information).
4167 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
4168 dump due to a division by zero error. (Addresses Debian bug #207082)
4170 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
4171 when reconnecting a directory requires creating a lost+found
4172 directory. (Addresses Debian bug #219640).
4174 Fixed a bug where e2fsck would bomb out if a journal needed to be
4175 replayed when using an alternate superblock.
4177 E2fsck will give an extra grace period before actually forcing a check
4178 if the laptop is running on battery. The next time fsck runs while
4179 the system is on the AC mains, or after the grace period is exceeded,
4180 the filesystem will be checked. (Addresses Debian bug #205177)
4182 E2fsck will inform the user when there are 5 or fewer mounts before a
4183 filesystem check will be forced. (Addresses Debian bug #157194)
4185 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
4186 We now correctly handle the case where there is an overlap between a
4187 block group descriptor or a superblock and a bad block indirect block.
4188 In the case where the indirect block is corrupted, we now suggest
4191 Fix byte swap bugs in e2fsck that caused the journal backup location
4192 in the superblock and symlinks created by SE Linux to be cleared
4193 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
4195 E2fsck -c now replaces the current list of bad blocks with the ones
4198 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
4199 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
4201 Fix a potential bug in e2fsck which could cause it to core dump when
4202 trying to print the location of the backup superblock.
4204 Protect against a potential core dump in e2fsck when printing a
4205 message about backup superblocks.
4207 Add support for backing up the journal inode location in the
4208 superblock. E2fsck will automatically save the journal information in
4209 the superblock if it is not there already, and will use it if the
4210 journal inode appears to be corrupted. ext2fs_add_journal_inode()
4211 will also save the backup information, so that new filesystems created
4212 by mke2fs and filesystems that have journals added via tune2fs will
4213 also have journal location written to the superblock as well.
4214 Debugfs's logdump command has been enhanced so that it can use the
4215 journal information in the superblock.
4217 E2fsck will now update all superblocks when moving the journal inode.
4219 Shrink the size of the e2fsck executable by moving some initialized
4220 variables to the BSS segment.
4222 E2fsck will avoid printing the ^A and ^B characters which bracket the
4223 progress bar when stdout and stdin are a tty device instead of a pipe
4224 to another program. (Addresses Debian bug #204137)
4226 Debugfs's mkdir command will automatically expand the directory if
4227 necessary. (Addresses Debian Bug: #217892)
4229 Fixed a bug in debugfs so that copying a file from /dev/null uses the
4230 correct mode bits. (Addresses Debian Bug: #217456)
4232 If the environment variables DEBUFS_PAGER and PAGER are not set,
4233 debugfs now searches for the appropriate pager to use, beginning with
4234 /usr/bin/pager, and then falling back to 'more' and 'less'.
4235 (Addresses Debian bug #221977)
4237 Debugfs will now support 2.6 device numbers where the major or minor
4238 number may be larger than 255. (Addresses Sourceforge bug #865289)
4240 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
4242 Chattr now stops processing options when it sees '--'. (Addresses
4245 Fix regression tests so they work correctly when e2fsprogs is compiled
4246 with configure --disable-htree.
4248 Fix bug in uuid library when there is no network card and the library
4249 is generating a time-based uuid. The random MAC address was not
4250 correctly generated to be a multicast address.
4252 Add compile_et extensions from Heimdall that were missed the first time
4255 Fix bug in badblocks when using O_DIRECT; we need to make sure that
4256 we're reading from an offset which is page aligned. For read-only and
4257 read-write tests, we try to recover after an error so that we can
4258 continue reading on page-aligned boundaries. (Addresses Debian Bug
4261 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
4264 Updated and clarified various man pages. (Addresses Debian Bug
4265 #206845, #222606, #214920, #232406)
4267 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
4269 Fixed various Debian packaging issues (see debian/changelog).
4274 Fixed a build problem so that e2fsprogs would compile with the
4275 --enable-profile option to configure selected. (Addresses Sourceforge
4278 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
4279 Bugzilla Bug #112448)
4281 Centralize code which calculates the location of the superblock
4282 and block group descriptors so that it is in a single library routine.
4284 Added two new functions, ext2fs_file_open2() and
4285 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
4287 Fix compile_et to output the correct prototype for
4288 initialize_xxx_err_table_r() in the header file. (Addresses Debian
4291 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
4293 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
4294 present. This is for when we try stuffing an int into void * pointer.
4296 Fix type-punning which can cause gcc 3.x to miscompile code by getting
4297 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
4298 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
4299 **'. The EVMS code uses an ugly union approach since we don't want to
4300 modify the EVMS interfaces.
4302 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
4303 aid build process on systems can use invoke GNU make as "gmake".
4305 Added regression testing for mke2fs.
4307 Fixed gcc -Wall nitpicks.
4309 Fixed various compiler warnings.
4311 Add portability fixes for FreeBSD and for using fsctl under Darwin to
4312 support ext2 ioctl's.
4315 E2fsprogs 1.34 (July 25, 2003)
4316 ===============================
4318 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
4319 a tight loop while waiting for a child fsck to exit in some cases.
4320 This burns CPU times which slows down the low-level filesystem check.
4322 Added code to mke2fs to assure that the default block size for a
4323 filesystem is at least as big as the sector size of the device, if it
4326 Changed mke2fs and resize2fs to round the default size of a filesystem
4327 to be an even multiple of the VM pagesize in order to avoid a Linux
4328 kernel bug introduced when the storage of the buffer cache was moved
4329 into the page cache.
4331 Mke2fs will warn the user when creating a filesystem with journaling
4332 and a blocksize greater than 4096. (Addresses Debian bug #193773)
4334 Fixed a bug in resize2fs which caused it to fail on filesystems with a
4335 non-empty bad block list. Resize2fs now discards any blocks on the
4336 badblock list which are no longer part of the filesystem as the result
4337 of a filesystem shrink. (Note: this means that shrinking and then
4338 enlarging a filesystem is no longer a reversible operation;
4339 information about bad blocks in the part of the filesystem which is to
4340 be chopped off will be lost.)
4342 Changed resize2fs so the user can use prefixes to specify the units of
4343 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
4344 and to make the error and informational messages explicitly display
4345 the blocksize used by the filesystem, in order to avoid confusion.
4346 (Addresses Debian bug: #189814)
4348 Added a new debugfs command, dump_unused, which dumps the contents of
4349 all unused blocks to stdout. (Useful as an emergency try-to-find
4350 deleted data command.)
4352 Added a new debugfs command, imap, which prints the location of a
4353 specified inode in the inode table.
4355 Fixed a bug in the badblocks program which caused it to use one bit of
4356 randomness in its non-destructive read/write test, instead of using a
4357 full 8 bits of randomness.
4359 Added a new option (-t) to badblocks, which allows the user to control
4360 the test pattern(s) used when checking a disk.
4362 The blkid probe function now more correctly detects UDF filesystems.
4364 Fixed a bug in the blkid library which caused it to not update its
4365 cache if a filesystem changes from having a label to not having a
4368 Fixed a bug in the blkid library wihch could avoid an infinite loop
4369 in blkid_find_dev_with_tag() if /proc is not mounted and there the
4370 /etc/blkid.tab file has not yet been created.
4372 Fixed the badblocks program so that the destructive read/write test
4373 honors the -c option, and to use O_DIRECT when possible to avoid
4374 thrashing the system block buffer cache.
4376 Fixed various NLS issues.
4377 - Added Czech and Swedish translations
4378 - Removed testing NYC translation
4379 - Fixed NLS support for message abbrevations in e2fsck
4380 - Remove de-utf.po, since we shouldn't have two versions using different
4382 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
4383 simplify the statistics reporting in e2fsck.
4385 Changed configure.in so that its defaults for *BSD systems no longer
4386 build an fsck wrapper, and not to install in /usr/local by default.
4388 Fixed some minor spelling errors/typo's in e2fsck and the configure
4391 Fixed various Debian packaging issues (see debian/changelog).
4393 Updated and clarified man pages. (Addresses Debian Bug #195616)
4398 Fix gcc -Wall nitpicks.
4400 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
4401 NLS support by default. (Added partial workaround for gettext/Darwin
4402 incompatibility problems.)
4404 Added full MIT KRB5 and Himdall compaibility support to the com_err
4405 library and the compile_et program. (Addresses Debian bug #191900)
4407 Added the blkid_known_fstype() function to the blkid library, which
4408 returns true if it is passed a filesystem type which is recognized by
4409 the blkid probing functions.
4411 Improved the documentation for the blkid library.
4413 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
4414 returns the hardware sector size of a device, if it is available.
4416 Added a dependency in the blkid library's .so file to the uuid
4417 library, since the former uses the latter. (Addresses Debian bug
4420 Added --with-diet-libc and --disable-evms to the configure script.
4422 Fixed a minor memory leak in the badblocks program.
4424 Fixed a portability problem in tune2fs --- not all systems have strptime().
4426 Fixed a portability problem in debugfs with the use of getopt() more
4427 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
4430 Add support Windows support to ext2fs_get_device_size().
4432 Added (normally disabled) debugging code to the Unix I/O manager which
4433 causes it to disable all userspace caching if the NO_IO_CACHE is
4436 Changed the test I/O manager so it can always be linked into e2fsck,
4437 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
4438 configure script. The test I/O manager will only print any debugging
4439 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
4440 variables are set, which specifies which I/O operations are logged and
4441 a block number to watch, respectively. The log messages are sent to
4442 stderr by default, unless a filename is specified via the
4443 TEST_IO_LOGFILE environment variable.
4446 E2fsprogs 1.33 (April 21, 2003)
4447 ===============================
4449 Added a new utility program, logsave, which captures the output of a
4450 command in a log file, even if the containing directory hasn't been
4451 mounted yet (in which case the it saves the output in memory until it
4452 can write out the logfile). This is useful for capturing the
4453 output of fsck during the boot sequence.
4455 Fixed some portability problems that were causing problems under
4456 the Cygwin32 environment.
4458 Mke2fs now interprets a negative number to the -b option as a minimum
4461 Fixed a bug in mke2fs which was incorrectly checking the argument to
4462 the -g option if the default block size was used. (Addresses Debian
4465 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
4466 it can not find filesystem checkers for jfs, reseirfs, and xfs.
4468 E2fsck now updates the global free block and inode counters from the
4469 block group specific counters quietly. This is needed for an
4470 experimental patch which eliminates locking the entire filesystem when
4471 allocating blocks or inodes; if the filesystem is not unmounted
4472 cleanly, the global counts may not be accurate.
4474 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4475 2.0 is not yet supported; this only pulled in the bug fixes: fixed
4476 possible hangs caused by bugs in calling waitpid, and not setting the
4477 pipe to non-blocking mode; also fixed a file descriptor leak; made
4478 sure all functions call log entry/exit functions.)
4480 Badblocks now flushes its output file as bad blocks are discovered.
4482 The uuid library is now more paranoid about assuming the correctness
4483 of the /dev/random device; it mixes in a stream of bytes from
4484 random/srandom, just in case.
4486 Update Debian files to reflect the fact that I am now the Debian
4487 maintainer of e2fsprogs. Other various Debian-specific packaging
4490 Move the source tarball generation functions from the top-level
4491 makefile to the util/gen-tarball script.
4493 Updated the Turkish .po translation file.
4495 Added Heimdal and MIT krb5 extensions to the com_err library to make
4496 it more compatible with com_err libraries from those distributions.
4498 Changed dumpe2fs to always display the superblock fields relating to
4499 the journalling and/or directory indexing feature even if those
4500 features are not enabled.
4502 Updated and clarify copyright statement vis-a-vis alpha releases of
4505 The ss library will now try to dynamically link to the readline
4506 library and use it if it is present in the system. This means that
4507 the debugfs program now has line editing and history features. The
4508 SS_READLINE_PATH environment variable is used to find a readline or
4509 readline-compatible library.
4511 E2fsck now finds most duplicate filenames (all when rebuilding all
4512 directories via the -D option) and offers to delete or rename
4513 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
4515 Fix bug in e2image. When writing out a raw image file, include data
4516 blocks from symlinks that do not store the symlink within the inode.
4518 Fix bug in resize2fs which incorrectly moved the block and inode
4519 bitmaps for sparse superblock filesystems and incorrectly marked
4520 blocks as in use. (Addresses Debian bug #174766)
4522 Added a new shared library, the blkid library, which efficiently
4523 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
4524 and UUID filesystem specifiers without needing to search all of the
4525 devices in the system. Instead, the device is looked up in a cache
4526 file, and then verified to make sure the blkid cache is correct.
4528 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
4529 the device name, using the blkid library. (Addresses Debian bugs
4532 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
4533 used for spaces in device labels.
4535 Removed 32-bit limitations for debugfs's dump command.
4537 If the user specifies a large number of inodes, Mke2fs will
4538 automatically adjust the number of blocks per group to find a valid
4539 set of filesystem parameters.
4541 Add workaround to detect broken MD devices where when some of the
4542 underlying devices are marked read-only, writes to the MD device are
4543 silently dropped. E2fsck will detect if there is an attempt to run
4544 the journal twice, and abort with an error if this is the case.
4545 (Addresses IBM Bugzilla bug #1226)
4547 E2fsck will print an error if more than one of the -p/-a, -n or -y
4548 options are specified.
4550 E2fsck will fix HTREE corruptions in preen mode, without stopping the
4551 boot process. This is needed because the 2.4 ext2 filesystem
4552 accidentally had the INDEX_FL backwards compatibility code removed.
4554 Mke2fs no longer creates filesystems with the dir_index flag set by
4555 default; the user has to specifically request it.
4557 Update and clarified various man pages. (Addresses Debian bugs
4558 #173612, #175233, #175113, and #170497, #185945, #188318)
4560 Created man page for the mk_cmds program (from the libss library).
4565 Fix various gcc -Wall nits.
4567 Fixed a lot of portability problems that caused e2fsprogs not to build
4568 successfully under Solaris and Apple/Darwin.
4570 Fixed a Makefile dependency to allow building e2fsprogs using parallel
4573 Changes to create a subset distribution which consists only of the
4574 et, ss, uuid, and blkid libraries. The configure script and top-level
4575 makefile were changed to support working with a subset distribution.
4577 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
4578 actually used, and might people who are looking for
4579 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
4581 Updated debian files to fix a number of Lintian warnings.
4583 Updated config.guess and config.sub with newer versions from the FSF.
4585 Removed unnecessary libraries from being linked into the fsck, lsattr,
4586 chattr, and blkid executables.
4588 E2fsprogs 1.32 (Nomvember 9, 2002)
4589 ==================================
4591 Fixed a bug in the Unix I/O routines which caused needless writebacks
4592 of clean blocks from the unix_io cache (they were erroneously marked
4593 as being dirty, so they were getting written back to disk before
4594 getting evicted from the disk cache). This was harmless, but it
4595 significantly slowed down e2fsck.
4597 Made some other minor optimizations to the Unix I/O routines to save a
4598 small amount of CPU time.
4600 Updated internationalization files.
4603 E2fsprogs 1.31 (Nomvember 8, 2002)
4604 ==================================
4606 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
4607 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
4608 handling for child process that die unexpectly. Add a hack to force
4609 mkfs to create filesystems that won't cause problems with hardware
4610 that has 2k or 4k minimum blocksize requirements. Read from child
4611 processes in non-blocking mode, so that the GUI continues to update.
4613 Fix e2fsck so that it returns the appropriate exit code when the root
4614 filesystem has been changed, so that system's rc scripts will be told that
4615 the system needs to be rebooted.
4617 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
4618 was set, some of the descriptor blocks that should have been written
4619 out were getting skipped.
4621 Changed e2fsck to force out changes to the backup copies of the
4622 superblock and block group descriptors when important changes are made
4623 to those data structures.
4625 Fix a bug where e2fsck could erroneously mark a filesystem as being
4626 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
4627 introduced in e2fsprogs 1.28.)
4629 If journal debuging is enabled using --enable-jbd-debug, the debugging
4630 level is now set via the E2FSCK_JBD_DEBUG environment variable.
4632 If byteswapping support is disabled using configure --disable-swapfs,
4633 skip the tests which depend on byte-swapping, so that "make check"
4636 Lshattr will now display the indexed directory flag. Also, some of
4637 the more esoteric compression flags are supressed unless compression
4638 support has been enabled.
4643 E2fsprogs 1.30 (October 31, 2002)
4644 =================================
4646 When resizing a filesystem, and inodes need to moved, resize2fs will
4647 update the inode's ctime field, and the mtime field of the containing
4648 directories, so that incremental backups using dump/restore will work
4651 In order to avoid spurious errors, e2fsck wil check the last
4652 superblock write time to determine whether or not it can safely use
4653 the LOW_DTIME checks to determine if there are inodes on the orphan
4654 inode linked list that had somehow gotten disconnected. (Addresses
4655 Sourceforge bug #620980)
4657 Partition in /proc/partitions that being with the string "lvm" are
4658 considered real partitions even if they do not end with a number.
4660 Fixed a bug in the the uuid generation function, where if /dev/urandom
4661 is not present, but /dev/random is, and there isn't sufficient
4662 entropy, the get_random_byte function could spin a loop forever.
4664 E2fsck, mke2fs, etc. will now reliably notice when image files are
4665 mounted using the loopback interface. (Addresses Sourceforge bug
4668 When flushing buffers (as is done by badblocks, for example) check to
4669 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
4670 FDFLUSH ioctl which causes the MD device driver which causes confusing
4671 syslog messages about obselete ioctl messages. (Addresses Sourceforge
4674 Debugfs's write command now checks to see if the destination filename
4675 exists before creating it. (Addresses Sourceforge bug #478195.)
4677 When installing man pages, search for compressed man pages using all
4678 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
4680 Fixed a bug in fsck where multiple filesystems specified on the
4681 command were not being checked in parallel due to a logic bug
4682 introduced to support the FSCK_MAX_INST environment variable.
4684 We have added a new superblock field, s_mkfs_time, which indicates
4685 when a filesystem was created. It is set via mke2fs, and printed out
4686 by dumpe2fs, but is not actually touched by the kernel.
4688 Dumpe2fs has been made more robust by not aborting if there is an
4689 error reading the block/inode bitmaps; instead it will still print out
4690 the location of the block/inode bitmaps and inode table.
4692 Add support for the an alternative block group descriptor layout which
4693 allows for on-line resizing without needing to prepare the filesystem
4694 in advance. (This is the incomat feature flag meta_bg.)
4696 Add support for storing default mount options in the superblock, so
4697 that the filesystem can be mounted with specific mount options without
4698 needing to specify them on the mount command line or in the /etc/fstab
4701 Add support for a new inode flag, which is to be used for indicating
4702 the top of directory hierarchies for the Orlov block allocator.
4704 Fix e2fsck so that if it creates the lost+found directory, it does so
4705 with the more apporpriate permissions of 0700. Also change
4706 mklost+found so that it also creates the directory 0700.
4708 Fixed format bug in e2fsck if NLS is in use.
4710 Add a German translation for e2fsprogs's NLS support.
4712 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
4713 the beginning of the inode table. This won't matter much, since if
4714 there is a bad block at the beginning of the inode table, the root
4715 directory won't be available. But at least e2fsck won't crash in this
4718 Fixed endian problems in the htree code for e2fsck and debugfs.
4720 When byte-swapping a filesystem on a PPC architecture, byte-swap the
4721 bitmaps since the historical big-endian ext2 variant had byte-swapped
4722 bitmaps, and the ext2fs library assumes this. This fixes the
4723 regression test suite on PPC machines.
4725 Fix e2image so that it handles a bad block in the inode table
4728 E2fsck now uses a more sophisticated algorithm to salvage corrupted
4729 directories that recovers more information in the corrupted directory
4732 E2fsck now performs additional consistency checks on indexed (HTREE)
4735 Fix bug where efsck might get confused about whether a completely
4736 empty directory block is an empty leaf block or an interior htree
4737 node. This could cause e2fsck to get confused into think that a valid
4738 indexed directory was corrupted.
4740 E2fsck no longer creates an empty directory entry at the end of a
4741 directory block when optimizing a directory. This would cause some
4742 earlier versions of the dxdir kernel code to corrupt the directory
4743 when attempting to split a node containing an empty directory entry.
4745 E2fsck could sometimes in rare circumstances leave the indexed flag
4746 set after a small directory was optimized by compressing it instead of
4747 indexing it. (This should never happen in real life, since
4748 directories that small wouldn't have been indexed, but better safe
4751 E2fsck now only updates the master superblock in all cases. This
4752 slightly shortens its run time.
4754 Ext2ed can deal with directory entries of length 0; previously it
4755 would get stuck in an infinite loop.
4757 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
4758 specifiers. (Sourceforge patch #613447)
4760 Badblocks will now work correctly on read-only devices such as
4761 CD-ROM's. (Sourceforge patch #600451)
4763 Updated and clarified man pages. (Addresses Debian bug #167108)
4766 E2fsprogs 1.29 (September 24, 2002)
4767 ===================================
4769 Fixed a bug in e2fsck which could corrupt a directory when optimizing
4770 it (via the -D option) or rebuiliding the hash tree index with a 1 in
4771 512 probability, due to a fence post error.
4773 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
4776 Mke2fs now enables the directory indexing flag by default. (Since
4777 this is a compatible feature flag, it's safe to do so.)
4779 Tune2fs will support setting the directory indexing feature flag. It
4780 will automatically set up the default hash algorithm and hash seed
4781 fields in the superblock.
4783 If the bone-headed user enters the root filesystem twice in
4784 /etc/fstab, the -R option which skips the root filesystem will skip
4785 all of them. (Addresses Debian bug #159423). Note! This is not a
4786 precedent for dealing intelligently with any other kind of doubled
4787 entry in /etc/fstab!
4793 Removed perror declaration in lib/et/internal.h. All modern systems
4794 can be expected to define perror() these days. Besides, the lib/et
4795 code wasn't using perror at all anyway. :-)
4798 E2fsprogs 1.28 (August 31, 2002)
4799 ================================
4801 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
4802 for setting the htree flag is not included yet, although it can be
4803 manually turned on via the debugfs program.
4805 Clarified e2fsck error message which is printed when it cannot find
4806 sufficient contiguous block when relcating filesystem metadata.
4808 Added support for building an EVMS plugin module for ext2/3. This
4809 module is substantially the same as the EVMS module shipping with EVMS
4810 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
4811 for use with EVMS 1.0 (which did not include the ext2 plugin module),
4812 if the configure --enable-old-evms flag is given.
4814 Fsck will search through EVMS volumes when trying to resolve
4815 filesystem specifications such as LABEL=xxx or UUID=xxx.
4817 Added a new utility program, /sbin/findfs, which will return
4818 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
4821 Update and clarified various man pages. (addresses Debian Bug #145044,
4822 #146437, #131350, #151990, #144621, #141938)
4824 If there are no filesystems specified on fsck's command line, fsck now
4825 treat that as if the -As options were given. Previously it would
4826 simply do nothing. (Addresses Debian Bug #153102)
4828 Mke2fs no longer treats a failure to be able to clear the MD signature
4829 at the end of the filesystem as a fatal error. (Addresses Debian Bug
4832 The e2p library functions (which are used by lsattr and chattr) now
4833 double check to make sure the file is a regular file or directory
4834 before attempting to use the ext2 ioctls. Some device drivers
4835 unfortunately respond to the ext2 ioctl's with unknown behaviour.
4836 (Addresses Debian Bug #152029).
4838 The extended attribute handling has been updated to correspond with
4839 the latest V2 bestbits ACL code.
4841 Fixed bug in e2fsck which caused it to not clear the dtime field when
4842 processing truncated inodes on the orphan list. This could cause data
4843 loss(!) if a filesystem is rebooted before a truncate has been
4846 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
4847 algorithms. This makes e2fsck much faster in the case of severely
4848 corrupted filesystems where a large number of blocks are claimed by a
4849 large number of inodes. (Thanks to the 2.5 IDE device driver for
4850 inspiring this work.)
4852 Resize2fs has been significantly sped up when shrinking and expanding
4853 a filesystem by a very small number of blocks (for example, when EVMS
4854 is converting a partition to be an EVMS legacy volume).
4856 Added a new option to e2fsck, -D, which will optimize or compress all
4857 of the directories in the filesystem.
4859 E2fsck now catches SIGINT and SIGTERM to make sure it will can
4860 properly clean up and only exit at safe points. Fsck will pass
4861 SIGINT/SIGTERM to its child processes, and wait until they have all
4862 exited before it exits.
4864 The uuid parsing code in the uuid library now properly complains when
4865 an illegally formated uuid is presented to it. (Addresses Debian bug
4868 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
4869 and 2.4.17, since the workaround can cause problems when using a 2.4
4870 kernel with an old version of glibc built with the 2.2 headers.
4872 Fixed a bug in mke2fs where it wasn't properly clearing the initial
4873 superblock used by other filesystems. (Addresses Debian bug #147256.)
4875 Added support for the synchronous directory feature written by Andrew
4878 The debugfs program can delete directories using the rmdir command.
4880 Add support for 8k and 16k filesystems (for systems with page sizes
4881 that are greater or equal to 8k or 16k, respectively). Note that
4882 these filesystems can not be mounted on x86 systems, or other systems
4883 with only 4k page sizes, due to limitations in the current Linux VM
4886 Resize2fs requires that the filesystem state be valid and have no
4887 errors; otherwise, e2fsck -f must be run first. (Previously it simply
4888 required that the last fsck time be greater than the last mount time.)
4890 Configure now defaults the man pages directory to /usr/share/man on
4893 E2fsck now offers to truncate inodes which contain too many blocks (so
4894 that i_blocks would overflow. Also fixed handling of large sparse
4897 E2fsck now more completely checks for symlink validity, including
4898 requiring NULL termination and length checks.
4900 E2fsck will offer to try forcing a disk write to remap a bad block
4901 after finding a read error when reading a filesystem metadata block.
4903 Fixed a bug in debugfs which caused the -b and -s options to crash
4904 debugfs, as well as breaking the testb, setb, and clearb functions.
4906 Added a bmap command to debugfs which calculates the logical to
4907 physical block mapping for a particular inode.
4909 Fixed a bug in code which checked to see if a device was mounted which
4910 sometimes (rarely) failed in the case of a plain file.
4912 Fixed a bug in resize2fs where when it reported an error, it would
4913 print a message erroneously indicating that the filesystem had been
4914 resized before it aborted.
4916 When resizing a plain file which is smaller than the requested size,
4917 resize2fs will attempt to extended the file so that programs like
4918 e2fsck will not complain that the file is too small.
4920 Resize2fs will print the actual new size of the filesystem when it is
4923 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
4924 information on big-endian systems.
4930 Fixed collisions with C++ reserved words.
4932 Added portability fixes for building e2fsprogs on the HURD and AIX.
4934 Added the ext2ed program for creation of test cases. (ext2ed has many
4935 limitations and bugs which make it unsuitable for production use.)
4937 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
4938 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
4939 name_len field is byte swampped on big-endian machines, since in the
4940 V2 structure, name_len is a char field which is doesn't need to be
4941 byte swapped --- except if an old-style kernel had byte-swapped the
4942 name_len field as part of the V1 structure.
4945 E2fsprogs 1.27 (March 8, 2002)
4946 ==============================
4948 The warning messages for mke2fs now go to standard error.
4950 Fixed to make sure "make check" runs all of the test programs with
4951 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
4953 The mke2fs program checks the boot sector for the BSD disk label, and
4954 avoids erasing it if it is there.
4956 Fixed a bug in e2fsck which caused it to core dump if the journal
4957 inode was missing when it was supposed to be there.
4959 E2fsck now prints ranges in pass 5 when printing deltas for the block
4962 Debugfs's "ls -l" command now will print out the file type information
4963 in the directory entry.
4965 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
4966 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
4968 Debugfs can now examine the experimental directory indexing
4971 Fixed bug in debugfs which caused it to core dump if modify_inode is
4972 called without an open filesystem.
4974 The debugfs lsdel command now runs its output through a pager first.
4976 When installing manual pages, remove the compressed manual pages first.
4978 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
4980 Fix the 2.4 resource limitation workaround introduced in 1.26 which
4981 actually broke things on mips32, sparc32, and Alpha platforms.
4983 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
4984 (which is required by the newer libintl libraries).
4989 Fixed various gcc -Wall complaints.
4991 Fixed a few memory leaks in the e2fsck journaling code, and in the
4992 ismounted code checking for a swap device.
4994 Add new inode I/O abstraction interface which exports an inode as
4997 Exported ext2_file_flush as a public interface.
4999 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5001 Lots of small random portability fixes to make e2fsprogs build under
5002 AIX --- even without the 5L compatibility toolkit, and even using the
5003 uber-crippled AIX native C compiler.
5006 E2fsprogs 1.26 (February 3, 2002)
5007 =================================
5009 Dumpe2fs will keep going now if the bad block inode can't be read.
5010 (Previously it stopped with a fatal error.)
5012 E2fsck will now give an opportunity to run the journal even if the
5013 recovery flag is not set. This is the default behaviour if e2fsck is
5014 using a backup superblock, since the needs_recovery flag will never be
5015 set in the backup superblock copies.
5017 E2fsck now automatically finds the backup superblock/group descriptors
5018 even when the primary superblock is completely destroyed for 2k and 4k
5019 filesystems. (Previously it just guessed/assumed that we were dealing
5020 with a 1k filesystem in that case, and users had to manually specify
5021 the backup superblock number.)
5023 Fixed a bug in e2fsck where it dereferences a null pointer when there
5024 is a problem opening a filesystem in preen mode.
5026 E2fsck now handles external journals correctly; previously it trashed
5027 the external journal device if the journal needed to be replayed.
5029 Work around ulimit incompatibility problem caused by recent 2.4
5030 kernels; the unix IO module will automatically try to set any resource
5031 limits to be infinite on startup.
5033 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5034 bitmap if it wasn't present and the blocksize was 2k or 4k.
5035 (Addresses Debian Bug #116975)
5037 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5038 clearing the new V2 fields if they do not make sense or if the ext3
5039 superblock is version 1 superblock.
5041 E2fsck will automatically relocate the ext3 journal from a visible
5042 file (i.e., /.journal) to an hidden inode if the filesystem has been
5043 opened read/write. This allows the users to add a journal while the
5044 filesystem is mounted, but the next time the system is rebooted, the
5045 journal file will disappear. This avoids problems with backups,
5046 stupid operators with superuser bits, etc.
5048 Fix a bug in fsck where it would not support a filesystem type of
5049 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5051 Fsck now supports fstab entries of the form "ext3,ext2". It will also
5052 automatically identify reiserfs filesystems.
5054 The number of processes spawned by fsck can now be limited using the
5055 FSCK_MAX_INST environment variable.
5057 Fsck now searchs the LVM proc hierarchy to find logical volumes which
5058 should be searched for UUID and label information.
5060 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5061 limit if at all possible, when opening a block device. (The filesize
5062 limit shouldn't be applied against writes to a block device.)
5064 In mke2fs and e2fsck, specifying the -c option twice will now do
5065 a read/write test on the disk. Update the man pages to encourage
5066 using the -c option, and to discouraging running badblocks separately,
5067 since users tend to forget to set the blocksize when running
5070 Mke2fs now automatically clears the immutable attribute on a
5071 pre-existing .journal file left over from a previous failed attempt to
5072 add a journal to an alreadyy-mounted filesystem.
5074 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
5077 Mke2fs now creates the lost+found directory with permissions of 0700,
5078 so that files that had previously lived in protected directory are
5079 safe if they get dropped in lost+found and the system administrator
5080 doesn't deal with immediately. (Addresses Debian #bug 118443)
5082 Mke2fs and e2fsck (and all programs that use the
5083 ext2fs_check_if_mounted function) will now properly identify that a
5084 device is mounted, even in cases where devfs has confused things with
5085 multiple devices names with the same identity, or if a dim-witted
5086 system administrator has done something stupid like creating device
5087 file aliases in their home directory. Also now checks for swap devices
5088 by using /proc/swaps. (Addresses Debian bug #106622)
5090 Added a new option (-T) to tune2fs which sets the time a filesystem
5093 Speed up e2image when creating sparse raw image files by optimizing
5094 away excess lseek() system calls.
5096 Fix support of large (> 2GB) files when used as a filesystem in
5097 mke2fs, tune2fs, debugfs, and findsuper.
5099 Debugfs's stat and icheck commands now properly deals with large (>
5102 Debugfs's set_super_value command now prints out the list of valid
5103 superblock fields which can be set using the command.
5105 Debugfs's rm and kill_file command now updates the superblock free block
5106 and inode counts, thus keeping the filesystem consistent.
5108 Debugfs's lsdel command now takes an optional argument which allows
5109 the user to only see the most recently deleted files.
5111 A new command (undel) was added to debugfs which automates
5112 undeleting a deleted inode and linking it back to a directory.
5114 Debugfs's ls command now takes a new option, -d, which lists
5115 deleted directory entries.
5117 Debugfs's testb, freeb, setb, and find_free_block commands now take an
5118 optional count argument.
5120 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
5121 be used to signal that a particular inode should not be eligible for
5122 tail-merging --- this is needed for programs like LILO.
5124 The findsuper (an unreleased, uninstalled utility program) has been
5125 improved to add extra validity checks and to add a progress meter.
5126 (It is still an unsupported program; the officially supported way to
5127 recover from a trashed partition table is to use gpart; findsuper is
5128 for wizards only. :-)
5130 Debugfs was fixed to compile with "configure --disable-swapfs".
5132 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
5134 Added new translation file for Turkish.
5139 Fix general gcc -Wall complaints.
5141 E2fsprogs (mostly) works with the dietlibc.
5143 The programming texinfo file has been expanded to include description
5144 of additional libext2fs functions. (Still not compeltely done, but a
5145 lot of the more important functions have been documented.)
5147 Added a umask structure to struct_ext2_filsys, which currently only
5148 modifies the behaviour of ext2fs_mkdir(), but if we add any file
5149 creation functions to libext2fs, we should also make sure they respect
5152 The build-rpm script was fixed to be a bit more safe.
5154 The tests' Makefile now has a way of automating test case creation
5155 for e2fsck, using "make testnew".
5157 Created a new function, ext2fs_dir_iterate2 which passes more
5158 information to the callback function (identical to the one used by
5159 ext2fs_dblist_dir_iterate). The directory iterator functions take a
5160 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
5161 directory entries. If the directory entry is deleted, the callback
5162 function will be called with the entry paraemter set to
5163 DIRENT_DELETED_FILE.
5165 Added new functions, ext2fs_inode_alloc_stats and
5166 ext2fs_block_alloc_stats, which takes updates block/inode allocation
5167 statistics in the bitmaps, block group descriptors, and superblock
5168 when inodes or blocks are allocated or deallocated.
5171 E2fsprogs 1.25 (September 20, 2001)
5172 ===================================
5174 This is primarily a bug-fix release; no new features were added, but
5175 there are a number of embarassing bug fixes and cleanups applied.
5177 Fix a bug mke2fs which causes stack garbage to be written to disk when
5178 zapping disk sectors. (This bug could cause mke2fs to core dump for
5179 some kernels, I suspect with security enhancement patches.)
5181 Remove unneeded #include of <linux/config.h> which was breaking
5182 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
5184 Updated tune2fs man page to reflect the fact that adding or removing a
5185 journal doesn't require running e2fsck.
5187 Remove use of AC_REQUIRE from autoconf which had been used to prevent
5188 AC_CANONICAL_HOST from being called twice; unfortunately this causes
5189 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
5190 used outside of autoconf macros. Fortunately, it doesn't seem to be
5191 necessary any more, anyway.
5193 E2fsck will now not fall back to an alternate superblock if the user
5194 specifies the superblock location explicitly on the command-line.
5195 This allows easier recovery from a situation where the primary
5196 superblock and block groups are slightly corrupted, but the backup
5197 superblocks are completely broken.
5199 Fix problem which caused compile_et and mk_cmds to blow up if
5200 e2fsprogs was in a directory with a pathname that contained spaces.
5202 We are now more paranoid about checking the entry in /etc/mtab to make
5203 sure the filesystem is really mounted, since some broken distributions
5204 (read: Slackware) don't initialize /etc/mtab before checking non-root
5205 filesystems. (Slackware also doesn't check the root filesystem
5206 separately, and reboot if the root filesystem had changes applied to
5207 it, which is dangerous and broken, but there's nothing I can do about
5210 Make UUID library C++ friendly by adding appropriate extern "C"
5211 declarations and using const in the function declarations.
5213 Fix up the com_err texinfo file so that it can product a valid info
5214 file (previously, it could only be used to generate paper
5215 documentation using texinfo.tex).
5218 E2fsprogs 1.24a (September 2, 2001)
5219 ===================================
5221 Fix brown-paper bug in mke2fs which caused it to segfault when
5222 printing the version string.
5225 E2fsprogs 1.24 (August 30, 2001)
5226 ================================
5228 Revert the BLKGETSIZE64 support, since for some distributions, this
5229 ioctl has been used by an unofficial kernel patch to update the last
5230 sector on the disk, and this was causing disk corruption problems as a
5233 Mke2fs is now more careful about zapping swap space signatures and
5234 other filesystem/raid superblock magic values so that programs like
5235 mount who try to use hueristics to determine the filesystem type of a
5236 partition are less likely to be confused.
5238 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
5239 regular file (since Andreas Dilger's on-line resizing tools will set
5242 Fixed some minor texinfo, man pages nits for spelling errors,
5243 texinfo warnings, etc. (Addresses Debian bug #110621.)
5245 E2fsprogs program no longer print the filesystem version number
5246 (i.e. 0.5b), since it only confuses people and doesn't serve any real
5249 E2fsck will once again compile under libc5, since it will supply its
5250 own version of strnlen if necesssary.
5252 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
5253 when specifying the external journal device. tune2fs will also search
5254 devices looking for the externla journal debice when removing.
5256 E2fsprogs 1.23 (August 15, 2001)
5257 ================================
5259 Add initial support for extended attributes (EA); e2fsck will
5260 correctly handle a filesystem with EA's and check the EA blocks for
5263 E2fsck's symlink sanity checking has been cleaned up. It now checks
5264 the i_size value of fast symlinks, and checks for immutable flags
5265 being set of symlinks, etc.
5267 E2fsck now offers to clear inodes which are special files that have a
5268 non-zero i_blocks or i_size field. (The i_size field check was in the
5269 previous version of the code, but due to a bug it didn't offer to
5270 clear the inode unless i_size and i_size_high were both non-zero.)
5272 E2image can now create "raw" image files, which only contain the
5273 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
5274 debugfs, etc., can be run directly on the raw image file.
5276 Add support for the 64-bit block device patches.
5278 Fixed bugs in creating external journals with a 1k blocksize.
5280 Add initial support for external journals (so long as the external
5281 journal only supports a single filesystem) in e2fsck.
5283 Remove requirement for needing to run fsck on a filesystem after
5284 removing a journal (either internal or external).
5286 The man pages now document how to create and manage external journals.
5288 Speed up the check of an ext3 filesystems by avoiding a needless flush
5289 of all of the superblock and block group descriptors.
5291 Speed up creating an internal journal using tune2fs in the case where
5292 the filesystem has a lot blocks already allocated.
5294 Tune2fs has been fixed to make sure that only error messages go to
5295 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
5297 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
5298 now not set the sparse_super feature. (Addresses Debian bug #108165)
5300 Add support in fsck for the filesystem type "auto".
5302 Fsck -A will not try to interpret device names for filesystems which
5303 have a pass number is 0. (Addresses Debian bug #106696).
5305 Fsck prints a warning message if now valid filesystems are passed to
5306 it. (Addresses Debian Bug #107458.)
5308 E2fsck now gives an explicit warning if there filesystem still has
5309 errors at the end of the run. (Addresses Debian bug #104502)
5311 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
5312 reflects an error. E2fsck will also not run the orphan list if the
5313 filesystem contains errors, since the orphan list might be corrupted.
5315 E2fsck now prints the number of large files when given the -v option.
5317 Fixed minor memory leaks in e2fsck.
5319 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
5322 E2fsprogs 1.22 (June 22, 2001)
5323 ==============================
5325 Fixed a bug in e2fsck's handling of orphan inodes which are special
5326 files (i.e., block/character device files, named FIFO's, etc.).
5328 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
5329 tune2fs to fail at adding a journal to a mounted filesystem.
5331 Fixed a few big-endian bugs in e2fsprogs
5332 * The directory block functions were accidentally reporting
5333 some directories as corrupted when they weren't.
5334 * If e2fsprogs is compiled --disable-swapfs, the C language
5335 equivalents weren't being included for big-endian platforms.
5336 (Fixes Debian bug #101686).
5338 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
5343 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
5344 ioctls, and allow them to be defined for non-i386 platforms.
5346 The uuid.h header file is now protected against multiple inclusions.
5348 E2fsprogs is now being developed using BitKeeper. Changed the test
5349 scripts to deal with BK's stripping CR characgters from text files,
5350 and changed the top-level Makefile.in to avoid including BitKeeper
5351 files when generating the source tarball.
5354 E2fsprogs 1.21 (June 15, 2001)
5355 ==============================
5357 Added new configure flags which allow a subset e2fsprogs to be built;
5358 this is most useful for boot floopies, since the resulting shared
5359 libraries and programs are slimmed down by removing features that
5360 aren't necessary for a boot floppy. The new flags that were added
5361 are: --disable-swapfs, which removes support for byte swapping old
5362 legacy PPC/68k filesystems, --disable-debugfs, which removes support
5363 for debugfs from the libext2fs library, --disable-imager, which
5364 removes support for the e2image program, and --disable-resizer, which
5365 removes support for resize2fs.
5367 E2fsck now prints the number of mounts or days elapsed since the last
5368 check when e2fsck is forced to check an otherwise clean filesystem.
5370 Tune2fs now prints an informative message about how often a filesystem
5371 will be checked when adding a journal to the filesystem, to remind the
5372 user that he/she may want to adjust those parameters using tune2fs
5375 Worked around hurd brain-damage which causes e2fsck to sometimes
5376 believe a filesystem is the root filesystem based on device numbers
5377 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
5380 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
5381 erroneous error with the -F option was specified.
5383 Fixed a ext3 recovery bug in the revoke handling; synchronized with
5386 Fixed two bugs in e2fsck's handling of dup block handling, dealing
5387 with relatively uncommon edge cases: a directory with an indirect
5388 block which is claimed by another file, and when the last inode in the
5389 filesystem has blocks claimed by another file.
5391 E2fsck now checks to see if the i_size field of a fast symlink is too
5392 big, and offers to clear the symlink if so.
5394 E2fsck now checks to see if i_size_high of special files is non-zero,
5395 and offers to clear i_size_high.
5397 Fix e2fsck's handling of incompatible journal flags so that the user
5398 has chance to abort, and then has the option to clear out the journal
5399 entirely. (Addresses Debian bug #98527.)
5401 Fixed a bug in fsck which could cause it to core dump if a mix of
5402 standard and non-standard device names are used in /etc/fstab.
5403 (Debian bug #100559)
5405 Fixed a bug in debugfs which caused read errors when copying a file to
5408 The debugfs set_super_value command can now modify the s_lastcheck field.
5410 Fixed a bug in lsattr and chattr which was accidentally introduced in
5411 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
5412 directories correctly because the change modified the layout of struct
5413 dirent to be incompatible with the libe2p shared library.
5415 Cleaned up the mke2fs manual page and included a discussion about why
5416 it's good to periodically check the filesystem even when journaling is
5422 Fix general gcc -Wall complaints.
5424 The types needed by the ext2 header files are now provided by
5425 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
5427 Integers are now preferred to longs when trying to find a 32-bit type
5428 in ext2_types.h. Also, if linux/types.h has already been defined,
5429 don't try to redefine the types.
5431 Fixed make depend script so that it automatically corrects the
5432 pathname cleanups performed by make -M, so I don't have to fix them up
5435 Fixed the d_loaddump test case to be more robust, and not depend on
5438 Removed debugfs's dependence on pread(), which was accidentally
5439 intrudced in e2fsprogs 1.20
5441 Fixed a performance bug in the libext2fs's icount routine; the size
5442 estimate of the icount array was incorrectly being calculated.
5444 Removed use of the badblocks compatibility functions in the e2fsprogs
5447 Added paranoia code which protects against strange cases where /etc
5448 isn't on the root filesystem, or if /etc/mtab doesn't exist.
5450 The header file ext2_types.h is now installed.
5452 Autoconf is used to determine when we are on big-endian machines,
5453 instead of doing run-time tests, to save a few bytes of code.
5455 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
5456 functions are no longer inline functions, which saves space and
5457 doesn't really cost any real performance.
5459 The ext2fs library no longer depends on the e2p library. (What need
5460 there was of it --- namely, fsetflags, was coded in-line).
5462 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
5463 when the user is stupid and tries compiling the package using "make
5466 Miscellaneous code cleanups:
5467 * Added missing files from Makefile.in's SRCS file, so that
5468 their dependencies would be properly calculated.
5469 * Removed redundant code
5470 * Fixed comments in code
5471 * Removed no-longer unneeded argsused #pragma.
5474 E2fsprogs 1.20 (May 20, 2001)
5475 =============================
5477 Add support for replaying the ext3 journal purely in user mode,
5478 including handling the orphaned inode list. Used code contributed by
5479 Andreas Dilger, with bug fixes and the orphaned inode handling done
5482 The mke2fs and tune2fs programs can create or modify a filesystem to
5483 include an ext3 journal. Tune2fs also can be used to remove an ext3
5484 journal from a filesystem.
5486 E2fsck will now check for the existence of a linked list of orphan
5487 inodes in the superblock, and clear those inodes before starting the
5488 rest of the filesystem check (but after the journal playback).
5490 E2fsck now validates the file descriptor passed to the -C option,
5491 which saves against the completion bar getting written to an
5492 unexpected location, such as the disk being checked. (Debian
5493 bug/wishlist #55220)
5495 E2fsck will now bump the filesystem revision number from zero to one
5496 if any of the compatibility bits are set.
5498 Fixed a bug where a badly corrupted directory on a big endian system
5499 could cause e2fsck to die with a bus error. The
5500 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
5501 the ext2 library now does alignment sanity checks on the rec_len field
5502 of the directory entry before using it.
5504 The ext2 library has been enhanced to make tune2fs safe to run on
5505 mounted filesystems. (Users could usually get away with using tune2fs
5506 on mounted filesystems before, but with the advent of ext3 and
5507 journaling, it became important to make tune2fs was *really* safe for
5508 use even when the filesystem being modified is mounted.) E2label is
5509 now implemented by tune2fs using an argv[0] dispatch, so that e2label
5510 is also now safe for use on mounted filesystems.
5512 Added a new program, e2image, which creates a backup of critical ext2
5513 filesystem data structures. The generated image file can be examined
5514 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
5515 the image file to help recover very badly damaged filesystems.
5517 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
5518 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
5519 large file when deciding whether or not the filesystem has large files.
5521 Fixed lsattr and chattr so that they work correctly on large files.
5522 (Fixes Debian bug #72690.)
5524 Removed limitation in get_device_size() which imposed a one terrabyte
5525 filesystem limitation. (Most 2.2 kernels still have a signed int
5526 problem which cause 1 TB block device limitation. Fortunately, the
5527 kernel patches to fix this are much easier than fixing the 2TB
5528 limitation in the kernel. :-)
5530 A max_mount_count of zero is now treated as if no mount count were
5531 set. (Previously, no mount count was indicated by using -1, and a
5532 mount count of zero caused e2fsck to always be run.)
5534 Mke2fs supports two new filesystem types largefile and largefile4.
5536 Mke2fs now adds some randomness in s_max_mount_count so that multiple
5537 filesystems won't be all checked at the same time under normal
5540 Fixed bug in the progress bar printing code which could cause e2fsck
5541 to core dump on an illegal filesystem.
5543 Fixed bug in fsck which could allow more than one instance of e2fsck
5544 to be printing a progress bar. (Debian bug #65267)
5546 Fsck using a UUID or a LABEL specifier will work even if devfs is
5547 compiled into the kernel and not mounted. If the pathnames in
5548 /proc/partitions are incorrect, fsck will search /dev for the correct
5549 device (using the new ext2fs_find_block_device library function).
5550 Fsck now also checks the RAID devices first so that they are properly
5551 found when they are in use. Support has also been added to support
5552 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
5554 Fixed a bug in fsck which caused it not deal properly with 16
5555 byte long filesystem labels.
5557 Fsck's -t option has been made a lot more flexible. The semantics for
5558 what happens if a comma-separated list to fsck has been regularized,
5559 and it is now possible to filter what filesystems will get checked
5560 based what is in the filesystem's fstab entry's option field. (Debian
5563 The dumpe2fs program can now print out the group description
5564 information in hex, and also prints the location of the superblock and
5565 block group descriptor for those block groups that have them.
5567 Mke2fs now clears the ext2 superblock before it starts creating a
5568 filesystem, so that the superblock magic number is only written if the
5569 filesystem creation process successfully completes.
5571 The debugfs program's stat command now pretty-prints the blocks used
5572 by an inode so that it's more compact and informative.
5574 The debugfs stats command now uses the same libe2p code (which is used
5575 by dumpe2fs) to print the superblock header information. This is more
5576 complete, and it avoids a bit of code duplication.
5578 Added a new debugfs command, set_super_value (ssv) which allows the
5579 user to set arbitrary superblock fields.
5581 Debugfs was extended to support inode numbers in hex (by prefixing
5582 them with 0x), and so that modify_inode can set the inode generation
5583 number. Also, there is now a new function command called logdump
5584 which will dump an ext3 journal.
5586 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
5589 Debugfs's dump command now stops immediately upon reporting a disk
5590 read error. (Fixed a bug in ext2fs_file_read library routine which
5591 caused debugfs not to stop.) (Debian bug #79163)
5593 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
5594 checked before /etc/mtab is used, since /proc/mounts is more likely to
5597 Added portability fixes for Solaris and Linux/ia64.
5599 Various manual pages were clarified and cleaned up. (Fixed debian
5600 bugs #63442, #67446, and #87216)
5606 The e2fsck message printer now supports %Iu and %Ig, which will print
5607 out the inode's user and group owners, respectively.
5609 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
5610 that no longer dependent on the system having the correct version of
5611 the kernel header files.
5613 Added a new function to libext2, ext2fs_find_block_device(), which
5614 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
5615 device given its device number.
5617 Added a new function to libext2, ext2fs_sync_device, which centralizes
5618 all of the places which might try to use the BLKFLSBUF or FDFLUSH
5619 ioctls (and usually failing to define them since the system header
5620 files don't usually do this for us, and we're trying to avoid usage of
5621 kernel include files now).
5623 Added new utility programs in tests/progs: random_exercise and
5624 hold_inode. They aren't built by default; they're useful for
5625 exercising ext3 filesystem code.
5627 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
5628 the filesystem close functions to only update the superblock, and to
5629 not touch the block group descriptors. Needed by tune2fs when
5630 modifying a mounted filesystem.
5632 Got rid of struct ext2fs_sb and replaced it with the standard struct
5633 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
5634 source (but not binary) compatibility of some users of the ext2
5635 library. Those applications should just simply do a global search and
5636 replace of struct ext2fs_sb with struct ext2_super_block, and include
5637 the new header file <ext2fs/ext2_fs.h> which defines it.
5639 The ino_t type has been renamed ext2_ino_t to protect applications
5640 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
5641 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
5642 unexpected ABI change.
5644 The Makefiles have been reworked so that "make check" can be run from
5645 the top-level Makefile.
5647 Fix general gcc -Wall complaints and removed dead code.
5649 Remove use of NOARGS, because we assume everyone does ANSI C these
5652 Added build-rpm script from sct.
5654 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
5657 New function ext2fs_flush_icache which must be called if the
5658 application program modifies the inode table blocks without going
5659 through ext2fs_write_inode() interface.
5661 New ext2fs_check_mount_point() function, which will return the mount
5662 point of a device if mounted.
5664 The io_channel abstraction now has an optional interface,
5665 io_channel_write_range, which allows specific byte ranges to be
5668 The unix_io IO channel now supports write-through caching, so that
5669 journal creation is more efficient.
5671 Added x86 assembly language routines to support byte swapping, to
5672 reduce executable size.
5674 Fixed bug in the utility program subst so that it's possible to
5675 replace a substitution variable with a zero-length string.
5677 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
5678 slipped into some of the problem number.
5680 E2fsprogs 1.19 (July 13, 2000)
5681 ==============================
5683 Release the resize2fs program since the timeout before it could
5684 be released under the GPL has finally expired.
5686 Add experimental support needed for the ext2 compression patches.
5687 This requires compiling e2fsprogs with the --enable-compression flag
5688 to the configure script.
5690 Added ext3 journalling support. E2fsck will run the journal (if
5691 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
5692 installed as a symlink to e2fsck. Fsck has been taught about ext3,
5693 and treats it the same as ext2 in terms of the progress bar logic.
5694 Dumpe2fs will display the superblock journaling information if the
5695 filesystem has a journal. The ext2 library will now permit opening an
5696 ext3 filesystem with the recovery flag set. This is necessary for
5697 on-line dump's to work correctly, but there may be issues with this
5698 working well since ext3 is much less agressive about syncing blocks to
5699 the filesystem, since they're safe on the journal.
5701 Tune2fs and e2fsck have been changed to allow the mount_count check to
5702 be disabled by setting max_mount_count to -1. (This was already
5703 supported by the kernel.)
5705 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
5706 are used for ext3 as well.
5708 Added internationalization support for e2fsprogs; must be enabled
5709 by passing --enable-nls to configure.
5711 Always use the provided ext2fs header files to insulate ourselves from
5712 kernel version changes. Which include files are used by e2fsprogs
5713 have also been cleaned up to improve portability.
5715 Limit the number of times that e2fsck updates the progress bar so that
5716 people who are booting using a 9600 baud console don't get swampped by
5719 Improved the loop detection algorithm in e2sck's pass #3 so that it is
5720 much, much faster for large filesystems with a large number of
5723 The memory footprint for e2fsck is now slightly smaller than before.
5725 E2fsck now checks if special devices have a non-zero size, and offers
5726 to clear the size field if it finds such an inode.
5728 E2fsck now checks if special devices have the append-only flag set,
5729 and offers to clear the inode.
5731 E2fsck now properly handles some "should never fail" cases during a
5732 bitmap copy in pass5.
5734 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
5736 E2fsck now calculates the correct location of the backup superblock in
5737 the case of filesystem blocksizes > 1k.
5739 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
5740 which normally didn't cause problems under most filesystem parameters,
5741 but could cause a valid superblock to be rejected in extreme cases.
5742 Other checks for validating superblock values were made more
5745 Added non-destructive write testing to the badblocks program, courtesy
5746 of David Beattie. The badblocks also now has an option to input the
5747 current set of bad blocks, so that known bad blocks are skipped to
5748 speed up the badblocks test. There is also a persistent rescan
5749 feature which causes badblocks to run until it has completed some
5750 number of passes without discovering any new bad blocks.
5752 Badblocks now checks to see if the device is mounted and refuses to do
5753 the tests involving writing to the device if it is mounted. Also,
5754 badblocks now allows the number of blocks to be checked to be
5755 defaulted to the size of the partition.
5757 Fixed a bug in fsck which didn't allow non-root users to be able to
5758 check filesystems if there were any LABEL= or UUID= entries in
5761 The Hurd doesn't support the filetype filesystem feature. The mke2fs
5762 program now makes sure that for the Hurd, the filestype feature is
5763 turned off. E2fsck will check to see if the filetype feature is
5764 turned on for Hurd filesystems, and offer to turn off the feature.
5766 Mke2fs now has a safety check to make sure the number of blocks do not
5767 exceed 32 bits even on a 64 bit platform.
5769 Really fixed a bug in fsck to allow "fsck -As" to run interactive
5770 fsck's. (For those people who like to do interactive fsck's in the
5773 Debugfs has a few new features: the rdump command, which will do a
5774 recursive dump of a directory and all of its contents, and the lcd
5775 command which does a local chdir (much like the ftp command of the
5776 same name). In addition, the debugfs program and the open_filesystem
5777 command now takes three new options: -b and -s, which allows the
5778 blocksize and superblock location to be specified, and the -c option
5779 which is used in catastrophic situations where the block group
5780 descriptors are corrupt. If the -c option is specified, debugfs will
5781 skip trying to read in the block and inode bitmaps.
5783 Debufs's lsdel command was fixed to handle bad blocks in the inode
5786 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
5789 General improvements in error messages
5791 - Mke2fs prints a sane error message if the partition size is zero
5792 (usually because the partition table wasn't reread by the
5793 kernel due to the partition being busy), instead of "invalid
5794 argument passed to ext2 library while initializing superblock".
5796 - Fsck now prints more self-explanatory message if an invalid UUID=
5797 or LABEL= specification is passed to it.
5799 UUID library changed to use the LGPL.
5801 Fixed a bug in the UUID library where very rapid calls to the
5802 time-based UUID generator could cause duplicate UUID's to be returned.
5803 This was not a problem for e2fsprogs, but it could be a problem for
5804 other users of the library.
5806 Make the UUID library more robust in the face of missing or an
5807 improper /dev/urandom or /dev/random files.
5809 Added some random portability fixes for Solaris.
5811 Some minor man page updates.
5813 Fixed a memory leak in the ss library.
5819 We now try to use lseek64 and open64 from the LFS if possible.
5821 The 3rd parameter in e2p's print_flags is now a flags word, instead of
5824 The mark and unmark bitmap functions now return the previous state of
5825 the bit that was being changed, which is useful for some speed
5828 The following functions have been added to enhance the badblocks list
5829 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5830 ext2fs_badblocks_equal.
5832 The ext2 header files now have the latest journalling fields to the
5835 The ext2fs_mkdir function in libext2fs now properly backs out of error
5836 conditions robustly.
5838 Cleaned up makefiles:
5839 - to cleanly compile with the -j flag.
5840 - so distclean removes all generated files.
5841 - so in case of an error while installing header files, the make aborts.
5843 Fix test_script so that it works correctly when compiling in the
5846 The random UUID generation routine has been made slightly better in
5847 the case where /dev/random doesn't exist. (Use of randomly-based UUID
5848 is still not recommended if /dev/random doesn't exist, however; it's
5849 better to use the time/ethernet MAC address UUID in this case.)
5851 Clean up the build process so it's more friendly in case of missing
5854 The ext2fs header file can now be #include'd into C++ programs.
5856 The e2p.h header file is now installed.
5858 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
5862 E2fsprogs 1.18 (November 10, 1999)
5863 ==================================
5865 Fix a core dumping bug in e2fsck if an imagic inode is present or
5866 (more rarely) if the filesystem is badly corrupted enough that e2fsck
5867 has to restart pass 1 processing. E2fsck now closes the filesystem
5868 before freeing a large number of its data structures, so in the case
5869 of future memory faults, at least the fixed filesystem will be fully
5872 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
5873 imagic inode, it will offer to clear the imagic flag.
5875 E2fsck will now offer to clear the immutable flag on special files
5876 (device/socket/fifos) when running it in non-preen mode.
5878 E2fsck will now set the filetype when creating /lost+found, and when
5879 connected orphaned inodes to /lost+found.
5881 Debugfs's ncheck and icheck commands now handles the case where there
5882 are bad blocks in the inode table without bombing out.
5884 The badblocks list processing code has been made more efficiently for
5885 appending a large number of (ordered) badblocks to the badblocks list.
5887 Some minor man page updates.
5889 Fsck now allows interactive e2fsck's when using fsck -As (not a common
5890 mode, but some people like to do this in boot scripts for silly reasons).
5895 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
5896 with the problem code convention.
5898 The badblocks list regression test program has been updated to work
5899 with previously made API name changes.
5901 The ext2fs_free() command now uses the new badblocks API to avoid
5902 using the compatibility layer.
5904 Added new regression test cases; the run_e2fsck test script now
5905 supports the ability for a test case to run a prepratory command
5906 before running e2fsck.
5908 E2fsprogs 1.17 (October 26, 1999)
5909 =================================
5911 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
5914 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
5915 thus potentially causing problems if a binary UUID contained a NULL
5918 E2fsck now uses stricter checks for directory entries in pass 2:
5919 zero-length filenames are not allowed; neither are 8 byte long
5922 The debugfs "dirty" command now clears the filesystem valid bit.
5923 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
5924 bit in the in-core superblock image. The new functionality is more
5925 what the user expects, and is more useful.)
5927 Added a debugging hook to test parallel fsck; if the environment
5928 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
5929 will be checked in parallel when they normally would not be.
5934 Fixed some #ifdef's for compilation under the Hurd OS.
5936 Fixed minor W2K compatibility problems.
5938 Fixed some miscellaneous GCC warnings.
5941 E2fsprogs 1.16 (October 22, 1999)
5942 =================================
5944 Fixed a race condition bug in fsck; when printing a progress bar, if
5945 checking multiple filesystems in parallel, it was possible for fsck to
5946 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
5947 handler, which would cause it to terminate with a signal 10.
5949 E2fsck now properly handles filesystems that have the
5950 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
5951 filesystem into using or not using FILETYPE feature.
5953 E2fsck now properly handles filesystems that have the IMAGIC feature
5954 turned on (this is used on Linux AFS servers).
5956 The mke2fs program now creates filesystems that have the filetype and
5957 sparse_superblock features enabled by default, unless it is run on a
5958 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
5959 so there is now a new flag -O which allows the user to specify with
5960 which features she would like to create the filesystem; "mke2fs -O
5961 none" will create a filesystsem compatible with 2.0 kernels.
5963 The tune2fs program now has a -O option which allows the user to set
5964 and reset "safe" filesystem features. Currently, the only ones which
5965 allows to be modified are the filetype and sparse_superblock features.
5966 Note setting or clearing either feature will require running e2fsck on
5967 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
5968 requires that there is enough free space on the filesystem for the
5969 extra superblocks which will be created by e2fsck.)
5971 Debugfs can now set and print filesystem features in the superblock
5972 using the "features" command. Dumpe2fs will print out the complete
5973 set of features when listing the superblock.
5975 Dumpe2fs has new options -f (force) and -h (header-only).
5977 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
5978 message to come up. This could happen when decrementing or
5979 incrementing a link count could result in an overflow.
5981 Fixed a bug in e2fsck where the block count on the lost+found
5982 directory would not be properly incremented when the directory was
5983 expanded to the point where an indirect block needed to be allocated.
5985 E2fsck now makes some additional sanity checks on the superblock to
5986 avoid crashing or giving a memory allocation error if some of the
5987 values in the superblock are unresonable (but the superblock otherwise
5990 Fixed a bug in e2fsck where a very badly corrupted filesystem might
5991 require two passes to completely fix the filesystem. This happened if
5992 an inode claimed blocks that was part of the filesystem metadata
5993 (typically, when garbage was written into an inode table or indirect
5994 block, since this kind of filesystem corruption normally doesn't
5997 On the Alpha, glibc declares st_flags although it isn't actually used;
5998 the configure script was improved to detect this case so that
5999 e2fsprogs can avoid using the non-functional stat field.
6001 The manual pages were updated to use a more consistent formatting
6002 style consistent with standard Unix man pages. Mke2fs's man page
6003 added documentation for a few previously undocumented options.
6005 Fixed minor display bugs in tune2fs and mke2fs.
6010 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6012 Added features to parse and print feature strings into the e2p library.
6013 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6015 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6016 whose directory entries contain proper filetype information if the
6017 filesystem supports it.
6019 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6020 the directory entry filetype information. This is used to set the
6021 directory entry filetype information if the filesystem supports it.
6023 Fixed a bug in ext2fs_expand_dir() where the block count in a
6024 directory's inode would not be properly incremented when the directory
6025 was expanded to the point where an indirect block needed to be
6029 E2fsprogs 1.15 (July 18, 1999)
6030 ==============================
6032 Add configuration checks so that e2fsprogs will compile cleanly on
6033 Linux 2.3 kernels that have renamed i_version to i_generation.
6035 E2fsck now prints a progress/completion bar (and not just a simple
6036 spinner) if the -C0 option is requested or if it receives a SIGUSR1
6037 signal. Fsck will automatically manage the (potentially muliple)
6038 e2fsck processes to print completion bars if it is given a -C option,
6039 with the right thing happening if multiple filesystems are being
6040 checked in parallel.
6042 Mke2fs now has better automatic hueristics to determine the filesystem
6043 parameters to be used for a particular filesystem. Added a new option
6044 -T which allows the user to specify how the filesystem is to be used,
6045 which helps mke2fs do a better job selecting the filesystem parameters.
6047 Mke2fs now creates revision 1 filesystems by default, and with the
6048 sparse superblock feature enabled. The sparse superblock feature is
6049 not understood by Linux 2.0 kernels, so they will only allow read-only
6050 mounts of filesystems with this sparse superblocks.
6052 Fix bug where if /dev/null couldn't be opened (should never happen),
6053 e2fsck would hang in a tight loop.
6055 Make e2fsck handle the case where /lost+found isn't a directory.
6057 E2fsck now uses mallinfo if it exists to get accurate statistics about
6060 Fix bug in e2fsck where it wouldn't check to see if a disconnected
6061 inode had any problems before connecting it to /lost+found.
6063 Add check to e2fsck so it makes sure that total number of inodes in
6064 the filesystem is a sane number.
6066 Fix fencepost error when clearing an the end of the block bitmap which
6067 caused the last block in the bitmap not to get cleared.
6069 Cleaned up a number of messages in e2fsck:
6070 * The message "Group's #'s copy of the group descriptor..."
6071 was fixed so that the correct number would be displayed.
6072 * Added missing space in the "disk write-protected" error messsage
6073 * Cleaned up the error message printed when a non-interactive
6074 e2fsck needs to abort a check because the filesystem
6075 appears to be mounted.
6077 Added a new command-line utility, uuidgen, which will create and print
6080 Make debugfs's icheck command more robust by checking to make sure an
6081 inode has valid blocks before interarting over the inode's blocks.
6083 UUID generation now uses a random-based scheme whenever possible to
6084 prevent potential privacy problems.
6086 Man pages for all of the UUID functions in the lirbary were added.
6088 Fixed bug in fsck so it won't coredump if a filesystem not in
6089 /etc/fstab is given to it.
6091 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6092 that most of the other mount utilities understands.
6094 Mke2fs will make a filesystem even if it appears mounted if the force
6097 Dumpe2fs has new command-line options which allow a filesystem expert
6098 to specify the superblock and blocksize when opening a filesystem.
6099 This is mainly useful when examining the remains of a toasted
6102 The badblocks program has been updated to display correctly on disks
6103 with large block numbers.
6105 The badblocks program no longer gives spurious errors when errors
6106 occur on non-block boundaries, which is common if the blocksize is
6109 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6110 MKE2FS_SYNC environment variable is set. This is to work around a VM
6111 bug in the 2.0 kernel. I've heard a report that a RAID user was able
6112 to trigger it even using a 2.2 kernel, but hopefully it will not be
6113 needed for most Linux 2.2 users.
6115 Fixed miscellaneous documentation and man pages.
6120 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
6121 in e2fsck's pass1.c really should have been static.
6123 The return value of the uuid_compare() function was changed to make it
6124 match with the convetions used by strcmp, memcmp, and Paul Leach's
6125 UUID sample document.
6127 The "make depend" process has now been made more automated; it now
6128 automatically word-wraps the dependencies, and only replaces source
6129 Makefile.in if there has been a change in the dependencies. Also, a
6130 top-level "make depend" now recurses through all the subdirectories
6133 The Makefile in .../util has been changed so that subst is built using
6134 the native C compiler during a cross-compilation, since the subst
6135 program is only used during the build process. Also add an explicit
6136 rule to build util/subst by cd'ing to the correct directory and
6139 The man directories are defined in terms mandir, so that the configure
6140 script can override the location of the manual pages.
6142 The config files have been updated to recognize new machine types for
6143 both the i386 and alpha families.
6145 Fsck has been modified so that it will accurately create an
6146 fsck_instance even when the noexecute flag is set. This allows for
6147 accurate debugging of the fsck pass structure. Also, when the verbose
6148 flag is given twice, fsck will print debugging information about when
6149 fsck is waiting for jobs to finish.
6152 E2fsprogs 1.14 (January 9, 1999)
6153 ================================
6155 Fix the fstab parsing code so that it can handle blank lines and
6156 comment characters. Also, missing pass numbers need to be treated as
6159 Fixed a bug in e2fsck where under some circumstances (when e2fsck
6160 needs to restart processing after fixing an egregious inconsistency)
6161 it would try to access already freed memory.
6163 E2fsck now prints non-printable characters in directory entries and
6164 pathnames using '^' and 'M-' notation.
6166 Fixed chattr so that it will ignore symbolic links when doing
6167 recursive descent traversals. For both chattr and lsattr, no longer
6168 print the version string unless the -V option is given.
6170 Allow the system administrator to directly specify the number of
6171 inodes desired in the filesystem, for some special cases where this is
6174 Fix portability problems so that e2fsprogs can be compiled under Linux
6175 1.2 systems and Solaris systems.
6177 Update the config.guess file with a more recent version that will
6178 identify newer Linux platforms.
6183 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
6184 an inode number of zero is passed to them.
6186 E2fsprogs 1.13 (December 15, 1998)
6187 ==================================
6189 Fixed a bug in debugfs where an error messages weren't getting printed
6190 when the ext2 library routines to read inodes returned errors in the
6191 stat, cmri and rm commands.
6193 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
6194 provided, it won't create an inode table smaller than the minimum
6195 number of inodes required for a proper ext2 filesystem.
6197 Fsck now parses the /etc/fstab file directly (instead of using
6198 getmntent()), so that it can distinguish between a missing pass number
6199 field and pass number field of zero. This caused problems for
6200 diskless workstations where all of the filesystems in /etc/fstab have
6201 an explicit pass number of zero, and fsck could not distinguish this
6202 from a /etc/fstab file with missing pass numbers.
6204 E2fsck will create a /lost+found directory if there isn't one in the
6205 filesystem, since it's safer to create the lost+found directory before
6208 Fixed e2fsck so that it would detect bogus immutable inodes which
6209 happen to be sockets and FIFO files, and offer to clear them.
6211 If a filesystem has multiple reasons why it needs to be checked, and
6212 one of the reasons is that it is uncleanly mounted, e2fsck will print
6213 that as the reason why the filesystem is being checked.
6215 Cleaned up the output routines of mke2fs so that it doesn't overflow
6216 an 80 column display when formating really big filesystems.
6218 Added a sanity check to e2fsck to make sure that file descriptors 0,
6219 1, 2 are open before opening the hard disk. This avoids a problem
6220 where a broken program might exec e2fsck with those file descriptors
6221 closed, which would cause disastrous results if the kernel returns a
6222 file descriptor for the block device which is also used by FILE *
6225 Fixed up the e2fsck progress reporting functions so that the values
6226 reliably reach 100% at the completion of all of the e2fsck passes.
6228 Fixed minor documentation bugs in man pages and usage messages.
6233 Fixed a number of lint warnings in the ext2fs library and potential
6234 portability problems from other OS's header files that might define
6235 CPP macros for names like "max" and "min".
6237 ext2fs_badblocks_list_add() has been made more efficient when it needs
6238 to grow the bad blocks list.
6240 Fixed a bug in e2fsck which caused it to dereference a freed pointer
6241 just before exiting.
6243 Fixed the substition process for generating the mk_cmds and compile_et
6244 scripts so that they will work outside of the build tree.
6246 Add sanity check to e2fsck so that if an internal routine
6247 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
6248 and causing a core dump. This should never happen, but...
6250 E2fsprogs 1.12 (July 9, 1998)
6251 ==================================
6253 E2fsprogs now works with glibc (at least with the version shipped wtih
6254 RedHat 5.0). The ext2fs_llseek() function should now work even with
6255 i386 ELF shared libraries and if llseek() is not present. We also
6256 explicitly do a configure test to see if (a) llseek is in libc, and
6257 (b) if llseek is declared in the system header files. (See standard
6258 complaints about libc developers don't understand the concept of
6259 compatibility with previous versions of libc.)
6261 The ext2fs library now writes out the block group number in each of
6262 the superblock copies. This makes it easier to automatically
6263 determine the starting block group of the filesystem when the block
6264 group information is trashed.
6266 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
6267 which means that e2fsprogs will ignore the high 8 bits of the
6268 directory entry's name_len field, so that it can be used for other
6271 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
6272 E2fsprogs will now support filesystems with 64-bit sized files.
6274 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
6276 Added new program "e2label", contributed by Andries Brouwer. E2label
6277 provides an easy-to-use interface to modify the filesystem label.
6279 Fixed bug so that lsattr -v works instead of producing a core dump.
6281 Fixed a minor bug in mke2fs so that all groups with bad superblock
6282 backup blocks are printed (not just the first one).
6284 Mke2fs will check the size of the device, and if the user specifies a
6285 filesystem size larger than the apparent size of the device it will
6286 print a warning message and ask if the user wants to proceed.
6288 E2fsck has a new option -C, which sends completion information to the
6289 specified file descriptor. For the most part, this is intended for
6290 programs to use, although -C 0 will print a spinning character to the
6291 stdout device, which may be useful for users who want to see something
6292 happening while e2fsck goes about its business.
6294 Fixed a bug in e2fsck which could cause a core dump when it needs to
6295 expand the /lost+found directory, and sometimes the bitmaps haven't
6296 been merged in. Also fixed a related bug where ext2fs_write_dir_block
6297 was used to write out a non-directory block. (Which would be bad on a
6298 non-Intel platform with byte swapping going on.)
6300 Fixed bug in e2fsck where it would print a "programming error" message
6301 instead of correctly identifying where a bad block was in used when
6302 the bad block was in a non-primary superblock or block group
6303 descriptor. Also fixed a related bug when sparse superblocks are in
6304 use and there is a bad block where a superblock or block group
6305 descriptor would have been in a group that doesn't include a
6308 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
6309 the block group descriptor table is corrupt, it was possible to try to
6310 allocate a huge array, fail, and then abort e2fsck.
6311 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
6312 and subsitutes reasonable values if the descriptors are obviously bogus.
6314 If e2fsck finds a device file which has the immutable flag set and the
6315 i_blocks beyond the normal device number are non-zero, e2fsck will
6316 offer to remove it, since it's probably caused by garbage in the inode
6319 When opening a filesystem, e2fsck specially checks for the EROFS error
6320 code, and prints a specific error message to the user which is more
6323 If the filesystem revision is too high, change the e2fsck to print
6324 that this is either because e2fsck is out of date, or because the
6325 superblock is corrupt.
6327 E2fsck now checks for directories that have duplicate '.' and '..'
6328 entries, and fixes this corruption.
6330 E2fsck no longer forces a sync of the filesystem (with attendant sleep
6331 calls) at all times. The ext2fs_flush() function now performs a sync
6332 only if it needed to write data blocks to disk.
6334 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
6335 certain errors would not be properly reported.
6337 Updated and expanded a few points in the man pages which users
6338 complained wheren't explicit enough.
6340 Added special case byte-swapping code if compiling on the PowerPC, to
6341 accomodate the strange big-endian variant of the ext2 filesystem that
6342 was previously used on the PowerPC port.
6348 Removed C++ keywords from the ext2fs libraries so that it could be
6351 E2fsck's internal organization has now been massively reorganized so
6352 that pass*.c don't have any printf statements. Instead, all problems
6353 are reported through the fix_problem() abstraction interface. E2fsck
6354 has also been revamped so that it can be called as a library from a
6357 Added new fileio primitives in libext2fs for reading and writing
6358 files on an unmounted ext2 filesystem. This interface is now used by
6361 Added a new libext2fs function for mapping logical block numbers of
6362 a file to a physical block number.
6364 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
6365 a block, zeros it, and updates the filesystem accounting records
6368 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
6369 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
6371 The libext2fs functions now use a set of memory allocation wrapper
6372 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
6373 instead of malloc, free, and resize. This makes it easier for us to
6374 be ported to strange environments where malloc, et. al. aren't
6375 necessarily available.
6377 Change the libext2fs fucntion to return ext2-specific error codes
6378 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
6379 and depending on the existence of system error codes (such as EEXIST
6382 Renamed io.h to ext2_io.h to avoid collision with other OS's header
6385 Add protection against ext2_io.h and ext2fs.h being included multiple
6388 The types used for memory lengths, etc. have been made more portable.
6389 In generla, the code has been made 16-bit safe. Added Mark
6390 Habersack's contributed DOS disk i/o routines.
6392 Miscellaneous portability fixes, including not depending on char's
6395 The io_channel structure has a new element, app_data, which is
6396 initialized by the ext2fs routines to contain a copy of the filesystem
6399 ext2fs_check_directory()'s callback function may now return the error
6400 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
6401 really do the checking, despite the presence of the callback function.
6404 E2fsprosg 1.11 (June 17, 1997)
6405 ==============================
6407 Fixed e2fsck to detect (previously ignored) conflicts between the
6408 superblock or block group descriptors and block bitmaps, inode
6409 bitmaps, and inode tables.
6411 Fixed bug in e2fsck so that when the message printed out when a block
6412 or inode bitmap conflicts with other data, it has the correct group
6415 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
6416 to badblocks. This meant that not all of the filesystem was being
6417 tested for bad blocks!
6419 Fixed an array boundary overrun case which cropped up in
6420 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
6423 Adjusted the number of columns printed by mke2fs when displaying the
6424 superblock backups to avoid running over 80 columns when making a
6425 really big filesystem.
6427 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
6428 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
6429 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
6434 Fixed install rule in lib/ss so that ss_err.h is actually getting
6437 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
6438 bassed back to the caller.
6440 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
6441 setting the current inode number (which meant this function wasn't
6444 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
6445 blocks in the bitmap when increasing the size of the bitmap.
6447 Changed the initial number of blocks allocated by ext2fs_init_dblist()
6448 to be more realistic.
6450 Added a new function ext2fs_allocate_group_table, which sets up the
6451 group descriptor information (and allocates inode and block bitmaps,
6452 and inode tables for a particular group). The function was created by
6453 factoring out code form ext2fs_allocate_tables().
6455 Added a new function ext2fs_move_blocks which takes a bitmap of the
6456 blocks to be moved, and moves them to another location on the
6459 Make the unix_io channel's io_channel_flush implementation calls sync()
6460 to to flush the kernel buffers to disk.
6462 Added a new function ext2fs_dblist_count returns the number of
6463 directory blocks in dblist.
6466 E2fsprogs 1.10 (April 24, 1997)
6467 ===============================
6469 Mke2fs once again defaults to creating revision #0 filesystems, since
6470 people were complaining about breaking compatibility with 1.2 kernels.
6471 Warning messages were added to the mke2fs and tune2fs man pages that
6472 the sparse superblock option isn't supported by most kernels yet (1.2
6473 and 2.0 both don't support parse superblocks.)
6475 Added new flag to mke2fs, -R <raid options>, which allows the user to
6476 tell mke2fs about the RAID configuration of the filesystem. Currently
6477 the only supported raid option is "stride" which specifies the width
6480 Fixed bug in e2fsck where pass1b would bomb out if there were any
6481 blocks marked bad in the inode table.
6483 Fixed rare bug in mke2fs where if the user had a very unlucky number
6484 of blocks in a filesystem (probability less than .002) the resulting
6485 filesystem would be corrupt in the last block group.
6487 Fixed bug where if e2fsck tried to allocate a block to fix a
6488 filesystem corruption problem and the filesystem had no free blocks,
6489 ext2fs_new_block() would loop forever.
6491 The configure script now checks explicitly to see if "-static" works,
6492 since that can't be assumed to be true --- RedHat doesn't install
6493 libc-static by default.
6495 Fixed bug in libext2's block iterator functions where under some
6496 cirmcustances, file with holes would cause the bcount parameter to the
6497 callback function to be incorrect. This bug didn't affect any of
6498 e2fsprogs programs, but it was discovered by Paul Mackerras, the
6499 author of the PPC boot loader.
6501 Removed use of static variables to store the inode cache in libext2fs.
6502 This caused problems if more than one filesystem was accessed via
6503 libext2fs (static variables in libraries are generally a bad idea).
6504 Again, this didn't affect e2fsprogs programs, but it was discovered by
6507 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
6508 will compile cleanly with 1.2.13 kernels (even with a.out shared
6514 Added new functions to duplicate an ext2 filesystem handle, and its
6515 associated substructure. New functions: ext2fs_dup_handle(),
6516 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
6517 Other structures, such as the io_channel and the inode_cache, now have
6518 a ref count so that they only get freed when they are no longer used
6519 by any filesystem handle. (These functions were added as part of the
6520 development effort for an ext2 resizer).
6522 E2fsprogs 1.09 (April 14, 1997)
6523 ===============================
6525 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
6526 accidentally introduced in the 1.08 release. The overhead calculation
6527 was accidentally removed, which caused ext2fs_initialize() to not
6528 notice when the filesystem size needed to be adjusted down because
6529 there wasn't enough space in the last block group.
6531 Fixed bug in version parsing library routine; it was always parsing
6532 the library version string, instead of using the passed-in string.
6534 Clarified chattr man page.
6536 E2fsprogs 1.08 (April 10, 1997)
6537 ===============================
6539 E2fsck 1.07 was very slow when checking very large filesystems with a
6540 lot of files that had hard links (i.e., news spools). This was fixed
6541 by seriously revamping the icount abstraction. Added a formal test
6542 suite for the icount abstraction.
6544 Debugfs now has a "-l" option to the "ls" command, which lists the
6545 inode number, permissions, owner, group, size, and name of the files
6548 Fix a bug in e2fsck where when a directory had its blocks moved to
6549 another location during the pass 1b processing, the directory block
6550 list wasn't updated, so pass 2 wouldn't check (and correct) the
6551 correct directory block.
6553 E2fsck will now treat inodes which contain blocks which are claimed by
6554 the filesystem metadata by treating them as multiply claimed blocks.
6555 This way, the data in those blocks can be copied to a new block during
6556 the pass 1b--1d processing.
6558 E2fsck will attempt to determine the correct superblock number and
6559 display it in the diagnostic and warning messages if possible.
6561 Add support for a new (incompatible) feature, "sparse_super". This
6562 feature reduces the number of blocks which contain copies of backup
6563 superblocks and block group descriptors. (It is only an incompatible
6564 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
6565 support a new -s option; e2fsck will recognize filesystems built with
6566 this feature turned on.
6568 E2fsck now checks the library to make sure is the correct version,
6569 using new library functions. (This helps to diagnose incorrectly
6570 installed e2fsprogs distributions.)
6572 Dumpe2fs now prints more information; its now prints the the
6573 filesystem revision number, the filesystem sparse_super feature (if
6574 present), the block ranges for each block group, and the offset from
6575 the beginning of the block group.
6577 Mke2fs now distributes the inode and block bitmap blok so that the
6578 won't be concentrated in one or two disks in RAID/striping setups.
6579 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
6580 choose the largest blocks per group that be chosen. (For 2k blocks,
6581 you can have up to 16384 blocks/group; for 4k blocks, you can have up
6582 to 32768 blocks/group.) Previously mke2fs would not allow
6583 specification of more than 8192 blocks per group, even if you were
6584 using a 2k or 4k block group.
6589 Added a new function ext2fs_create_icount2() which takes a "hint"
6590 argument. This hint argument presets the icount array with the list
6591 of inodes which actually need to be in the icount array. This really
6592 helps to speed up e2fsck.
6594 Added a new function ext2fs_icount_validate() which checks the rep
6595 invariant for the icount structure. This is used mostly for testing.
6597 The error mesasage given when a bad inode number is passed to
6598 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
6599 EXT2FS_UNMARK_ERROR).
6601 Added a new function ext2fs_set_dir_block which sets the block of a
6602 dblist entry, given the directory inode and blockcnt.
6604 Added a new function ext2fs_get_library_version() which returns the
6605 current library version, and ext2fs_parse_version_string() which
6606 returns a version number based on a e2fsprogs version string.
6608 The icount functions will return EINVAL if the passed in inode number
6611 E2fsprogs 1.07 (March 9, 1997)
6612 ==============================
6614 E2fsck is now uses much less memory when checking really large
6615 filesystems (or rather, filesystems with a large number of inodes).
6616 Previously a filesystem with 1 million inodes required 4 megabytes of
6617 memory to store inode count statistics; that storage requirement has
6618 now been reduced to roughly half a megabyte.
6620 E2fsck can now properly deal with bad blocks appearing inside the
6621 inode table. Instead of trying to relocate the inode table (which
6622 often failed because there wasn't enough space), the inodes in the bad
6623 block are marked as in use.
6625 E2fsck will automatically try to use the backup superblocks if the
6626 primary superblocks have a bad magic number or have missing meta-data
6627 blocks (or meta-data blocks which are out of range).
6629 E2fsck's pass 3 has been made more efficient; most noticeable on
6630 filesystems with a very large number of directories.
6632 Completely revamped e2fsck's system of printing problem reports. It
6633 is now table driven, to make them more easily customizeable and
6634 extendable. Error messages which can be printed out during preen mode
6635 are now one line long.
6637 Fixed e2fsck's filesystem swapping code so that it won't try to swap
6638 fast symbolic links or deleted files.
6640 Fixed e2fsck core dumping when fixing a filesystem which has no
6641 directories (not even a root directory).
6643 Added a check to e2fsck to make sure that the length of every
6644 directory entry is a multiple of 4 (since the kernel complains if it
6647 Added a check to e2fsck to make sure that a directory entry isn't a
6648 link to the root directory, since that isn't allowed.
6650 Added a check to e2fsk to now make sure the '.' and '..' directory
6651 entries are null terminated, since the 2.0 kernel requires it.
6653 Added check to write_bitmaps() to make sure the superblock doesn't get
6654 trashed if the inode or block bitmap is marked as being block zero.
6656 Added checking of the new feature set fields in the superblock, to
6657 avoid dealing with new filesystem features that this package wasn't
6660 Fixed a fencepost error in ext2fs_new_block() which would occasionally
6661 try to allocate a block beyond the end of a filesystem.
6663 When the UUID library picks a random IEEE 802 address (because it
6664 can't find one from a network card), it sets the multicast bit, to
6665 avoid conflicting with a legitimate IEEE 802 address.
6667 Mke2fs now sets the root directory's owner to be the real uid of the
6668 user running mke2fs. If the real uid is non-zero, it also sets
6669 the group ownership of the root directory to be the real group-id of
6670 the user running mke2fs.
6672 Mke2fs now has more intelligent error checking when it is given a
6673 non-existent device.
6675 When badblocks is given the -vv option, it now updates the block that
6676 it is currently testing on every block.
6678 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
6679 currently correctly if PATH wasn't already set.
6681 Shared libraries now built with dependencies. This allows the shared
6682 library files to be used with dlopen(); it also makes the transition
6683 to libc 6 easier, since ld.so can tell which libc a particular shared
6684 library expects to use.
6689 Added new abstraction (defined in dblist.c) for maintaining a list of
6690 blocks which belongs to directories. This is used in e2fsck and other
6691 programs which need to iterate over all directories.
6693 Added new functions which test to see if a contiguous range of blocks
6694 (or inodes) are available. (ext2fs_*_bitmap_range).
6696 Added new function (ext2_inode_has_valid_blocks) which returns true if
6697 an inode has valid blocks. (moved from e2fsck code).
6699 Added new function (ext2fs_allocate_tables) which allocates the
6700 meta-data blocks as part of initializing a filesystem. (moved from
6703 Added a new I/O manager for testing purposes. It will either allow a
6704 program to intercept I/O requests, or print debugging messages to
6705 trace the activity of a program using the I/O manager.
6707 The badblocks_list functions now store the bad blocks in a sorted
6708 order, and use a binary search to speed up badblocks_list_test.
6710 The inode scan function ext2fs_get_next_inode() may now return a soft
6711 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
6712 those cases where part of an inode table is missing or there is a bad
6713 block in the inode table.
6715 Added a new function (ext2fs_block_iterate2) which adds new arguments to
6716 the callback function to return a pointer (block and offset) to the
6717 reference of the block.
6719 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
6720 application to jump to a particular block group while doing an inode
6723 The badblocks list functions were renamed from badblocks_* to
6724 ext2fs_badblocks_*. Backwards compatibility functions are available
6725 for now, but programs should be modified to use the new interface.
6727 Some of the library functions were reorganized into separate files to
6728 reduce the size of some programs which statically link against the
6731 Put in some miscellaneous fixes for the Alpha platform.
6734 E2fsprogs 1.06 (October 7, 1996)
6735 ================================
6737 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
6738 smash the backup copies in ext2fs_close(). (The problem was that when
6739 e2fsck -p discovered the problem, while it was closing the filesystem
6740 and exiting, it was also blowing away the backup superblocks on the
6741 disk, which was less than friendly.) We now make it the case that we
6742 only write out the backup superblock and the back block descriptors if
6743 the filesystem is completely free from problems.
6745 Fixed a bug in block_interate in the lib/ext2fs library which caused
6746 e2fsck to fail on GNU Hurd-created filesystems.
6748 Add support for Linux/FT's bootloader, which actually uses
6749 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
6752 Add support for the "A" (no atime update) attribute. (Note: this
6753 attribute is not yet in production kernels.)
6755 The test suite is not automatically run when doing a "make all" from
6756 the top level directory. Users should manually run "make check" if
6757 they wish to run the test suite.
6759 Upon a preenhalt(), make the printed message more explicit that
6760 running e2fsck "MANAULLY" means without the -p or -a options.
6762 In e2fsck, if a disconnected inode is zero-length, offer to clear it
6763 instead of offering to connect it to lost+found.
6765 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
6766 e2fsck to be run over it, change e2fsck to explicitly display this
6769 For dumpe2fs and e2fsck, cause the -V option to print out which
6770 version of the ext2fs library is actually getting used. (This will
6771 help detect mismatches of using a 1.06 utility with a 1.05 library,
6777 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
6778 the naming convention.
6780 In ext2fs_initialize(), make sure the description for the inode bitmap
6781 is correctly initialize.
6783 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
6785 E2fsprogs 1.05 (September 7, 1996)
6786 ==================================
6788 Add support for new fields in the ext2 superblock --- volume name,
6789 volume UUID, and last mounted field. Dumpe2fs displays these fields,
6790 tune2fs and mke2fs allows you to set them. E2fsck will automatically
6791 generate a UUID for those volumes that don't have them.
6793 Put in support for e2fsck to recognize HURD specific ext2 features ---
6794 most notably, the translator block. The e2fsprogs tools will now use
6795 the creator_os field in the superblock to correctly handle different
6796 OS-specific variants of the ext2 filesystem.
6798 E2fsck now fixes inodes which have a the deletion time set, but which
6799 have a non-zero i_link_count field by offering to clear the deletion
6800 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
6801 ext2 kernel behavior) and offered to unlink the file.
6803 If e2fsck sets the clean bit, but nothing else, set the exit code
6804 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
6805 set the filesystem valid bit when it was previously cleared. :-) This
6806 was needed to make the HURD fsck driver happy.
6808 If the user refuses to attach an unattached inode, e2fsck will no
6809 longer set the inode's link count. Otherwise, the inode would end up
6810 getting marked as unused, which might cause loss of data later.
6812 Make the message issued by e2fsck when the superblock is corrupt less
6813 confusing for users. It now mentions that another reason for the
6814 "corrupt superblock" message might be that the partition might not be
6815 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
6817 Make the libext2 library more robuest so that e2fsck won't coredump on
6818 an illegal superblock where the blocksize is zero. (f_crashdisk is
6821 By default, create filesystems where the default checkinterval is 6
6822 months (180 days). Linux servers can be robust enough that 20 reboots
6823 can be a long, long time.
6825 Added configure flag --enable-old-bitops, which forces the bitops to
6826 use the old (native) bitmask operations. By default on the sparc
6827 platform, the standard ext2 bit ordering is now used.
6829 Added a new feature to e2fsck to byte-swap filesystems; this can be
6830 used to convert old m68k filesystems to use the standard byte-order
6831 storage for the superblock, inodes, and directory blocks. This
6832 function is invoked by using the '-s' option to e2fsck.
6834 Debugfs's "dump" command has been enhanced so that it writes out the
6835 exact size of the file so that the nulls at the end of the file are
6836 eliminated. The command also accept a new "-p" option which will
6837 attempt preserve to preserve the ownernship, permissions, and
6838 file modification/access times.
6840 Debugfs has two new options, -f and -R. The -R option allows the user
6841 to execute a single debugfs command from the command line. The -f
6842 option allows the user to specify a "command file" containing debugfs
6843 commands which will get executed.
6845 Dumpe2fs now pretty prints the check interval, instead of just
6846 printing the check interval as a number of seconds.
6848 Fix bugs in debugfs: the params command when no filesystem is opened
6849 no longer causes a core dump. It is now possible to unlink a file
6850 when a pathame containing a '/' is specified.
6852 Tune2fs has a new -C option which sets the number of times the
6853 filesystem has been mounted.
6855 Fix the chattr '-v' option so that it actually works. Chattr was
6856 being buggy about the -v option parsing.
6861 The directory lib/uuid contains a set of library routines to generate
6862 DCE compatible UUIDs.
6864 Extended ext2fs_namei() to handle symbolic links. Added new function
6865 ext2fs_nami_follow() which will follow last symbolic link in the case
6866 where the pathname points to a sym link.
6868 The ext2fs_block_iterate function will now return the HURD translator
6869 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
6870 iterator to return data blocks only. The ext2fs.h file now defines
6871 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
6872 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
6873 count field of the iterator callback function.
6875 The test script driver now takes an optional second argument, which is
6876 the test case to be run. This allows you to run a test case without
6877 needing to run the entire test suite.
6879 On Linux ELF systems, install the .so files in the correct places
6880 (/usr/lib). The .so files must be stored in the same directory as the
6883 Fixed miscellaneous HURD compilation issues with header file being
6884 included in the right order.
6886 Fixed debugfs so that it resets optind to zero, not one, since setting
6887 optind to zero is more correct.
6890 E2fsprogs 1.04 (May 16, 1996)
6891 =============================
6893 First "official" (1.03 was a limited release only) to support building
6894 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
6897 This package includes a RPM specs file, that it can be built using the
6898 RedHat Package Manager.
6900 E2fsck now prints a hint that if there are lots of incorrectly located
6901 inode bitmaps, block bitmaps, and inode table blocks, the user might
6902 want to try using e2fsck -b 8193 first, to see if that fares any
6905 For ext2 filesystem written with the hurd, debugfs will now print out
6906 the translator field when printing an inode structure.
6908 Lots of miscellaneous linking/installation cleanups:
6910 Libraries are now linked using a relative pathname, instead of
6911 relying on -L working correct. It doesn't, in many cases, including
6912 current versions of GNU ld. This guarantees that the build tree is
6913 linking with the right libraries, instead of the ones installed in
6916 Header files, man pages, and the et/ss shell scripts are now
6917 generated using a custom substitution script, instead of relying on
6918 the configure script. This prevents needless recompilation of
6919 files; in addition, the custom substitution script is much faster.
6921 e2fsck may now be linked dynamically, by using the
6922 --enable-dynamic-e2fsck flag to configure. This is not recommended,
6923 since it increases e2fsck's dependence on other files, but some
6924 people need to save disk space, and other critical programs on their
6925 systems were being linked dynamically anyway.
6927 Programs such as fsck which didn't need to be linked against
6928 libext2fs (or mke2fs which didn't need to be linked against libe2p)
6929 only link against libraries they actually need. Otherwise, those
6930 programs would require the presense of libraries that otherwise
6931 could be removed from a rescuse diskette.
6933 The ss include files are now installed correctly so they can
6934 actually be used by another package.
6936 If the profiling libraries are built, they are now installed on a
6937 "make install-libs".
6940 E2fsprogs 1.03 (March 27, 1996)
6941 ===============================
6943 Change the m68k bit numbering for bitmasks to match the bit numbering
6944 used by all other ext2 implementations. (This change was requested by
6945 the m68k kernel development team.)
6947 Support (in-development) filesystem format revision which supports
6948 (among other things) dynamically sized inodes.
6950 Fixed a bug in the ext2 library so that an intelligent error is
6951 returned if mke2fs is run with a ridiculously small number of blocks
6954 Fixed a bug in the ext2 library which required that the device be
6955 openable in read/write mode in order to determine its size. This
6956 caused e2fsck -n to require read/write access when it was not
6957 previously necessary.
6959 Fixed a bug in e2fsck which casued it to occasionally fail the test
6960 suite depending on which version of the floating point library it was
6963 Fixed a bug in e2fsck so that it now halts with a fatal error when
6964 certain superblock consistency checks fail. Previously it continued
6965 running e2fsck, with some potential confusing/damaging consequences.
6967 Added new flag to fsck which allows the root to be checked in parallel
6968 with other filesytems. This is not the safest thing in the world to
6969 do, but some system administrators really wanted it.
6971 Fixed -Wall flames in lib/ss.
6974 E2fsprogs 1.02 (January 16, 1996)
6975 =================================
6977 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
6979 Change e2fsck to print statistics of how many non-contiguous files are
6980 on the system. Note that a file which is larger than 8k blocks, it is
6981 guaranteed to be non-contiguous.
6983 In mke2fs, print a warning message if a user tries to format a whole
6984 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
6985 whole disk, the -F (force) option forces mke2fs to format a whole disk
6988 Fix a bug in fsck where in some cases it might start checking
6989 partitions in the next pass before it finishes checking partitions in
6990 the current pass. This still won't cause two partitions on the same
6991 disk will be checked, so it's rarely a problem in real life.
6993 Patch lsattr so that it won't hang when checking a named pipe.
6995 Minor compilation fixes:
6996 * Fix the order of libraries that were linked in debugfs.
6997 * Allow the sources to be compiled with -ansi turned on.
