1 E2fsprogs 1.43-WIP (December 28, 2013) -- 38cc555a5fc
2 ======================================
4 Add support for the ext4 metadata checksum feature.
6 Check to make sure file system features which can not be supported by
7 HURD are not enabled if the file system is created to be
14 Reduce the use of libc functions in libext2fs that may not be present
15 in the boot loader environment, at least for those functions that are
16 needed by boot loadsers such as yaboot.
18 Support for the MMP feature can now be disabled at compile time.
20 E2fsprogs 1.42.12 (August 25, 2014)
21 ===================================
23 Fix various e2fsck bugs when trying to repair bigalloc file systems.
25 E2fsck can now repair a file system with an overly large
26 s_first_meta_bg field, which had previously caused all e2fsprogs
27 programs to crash when trying to open such a file system.
29 Fix e2fsck so that it can correctly fix a number of rare file system
30 corruptions that were discovered when using a file system fuzzer.
32 Fix e2fsck so it does not try to write back block group descriptors if
33 they have not been modified.
35 Mke2fs program will now place metadata blocks in the last flex_bg so
36 they are contiguous. This reduces free space fragmentation in a
37 freshly created file system, as well as allowing mke2fs commands which
38 request extremely large flex_bg size to succeed.
40 Mke2fs now creates hugefiles more efficiently (with fewer extent tree
43 Fix a 32/64-bit overflow bug that could cause resize2fs to loop
44 forever. (Addresses-Launchpad-Bug: #1321958)
46 The resize2fs program will now use much less memory when resizing very
49 Fix a bug which could cause resize2fs to get confused and produce a
50 corrupted file system when shrinking a file system that had been
51 previously expanded and converted to use the meta_bg file system
52 format, but which no longer needs to use the meta_bg file system
53 format any longer. This typically happened with large (> 16TB) file
54 systems. (Addresses Debian Bug: #756922)
56 The e4defrag program will now defrag backwards-allocated files.
58 Fix tune2fs updating UUID's when manipulating file systems with
59 external journals (both the file system and journal UUID).
61 Fix tune2fs so it can remove an external journal for file systems with
64 Add a new debugfs command, "inode_dump", which prints the inode in hex
67 The debugfs's "set_inode_field" will now automatically allocate blocks
68 for indirect blocks and extent tree blocks.
70 Fix debugfs's "set_inode_field" so can properly handle
71 "block[IND|DIND|TIND]".
73 The debugfs "rdump" command will now take multiple source arguments.
75 Fixed a double close(2) bug in "rdump" and "rdump -p".
77 Fix debugfs's argument parsing for the freefrag command.
79 Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
80 (Addresses Launchpad Bug: #1356496)
82 Clarified messages that were confusing users in debugfs, e2fsck,
83 mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
86 Dumpe2fs will now complain if extra arguments are given to it.
87 (Addresses Debian Bug: #758074)
89 Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
91 Update Czech, French, Spanish, and Sweedish translations.
96 The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
97 number of system calls issued.
101 The libext2fs library will now more efficiently split an extent tree
102 index block when appending to an end of a file.
104 Fixed free block accounting for 64-bit file systems.
106 Add a new function ext2s_inode_size_set() which takes care of all of
107 the required feature flag modifications.
109 The regression tests no longer require the presence of the md5sum
112 Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
115 Fix various Coverity warnings (#1225003, #1229243, #1252003)
118 E2fsprogs 1.42.11 (July 9, 2014)
119 ================================
121 Add support so that mke2fs can create hugefiles so that they are
122 aligned relative to the beginning of the disk, instead of relative to
123 the beginning of the partition, using the mke2fs.conf configuration
124 parameter "hugefiles_align_disk".
126 Fix a bug which causes e2fsck to abort a journal replay on a file
127 system with bigalloc enabled. (Addresses Debian Bug: #744953)
129 Add sanity checks so that mke2fs will refuse insanely large flex_bg
130 counts specified by the -G option. Insanely large flex_bg sizes can
131 result in a file system which can't be unmounted, or with extremely
132 pessimal metadata layouts.
134 The mke2fs program will provide a better metadata layout for
135 moderately large (but believable) flex_bg counts, such as 133,072.
137 The mke2fs progam will also check the kernel version number to
138 determine whether the lazy_itable_init option is supported, so that
139 lazy inode table initialization can be used even if the ext4 is
140 compiled as a module which isn't loaded at the time that mke2fs is
143 Add description of ext4's mount options to the ext4 section 5 man
146 Improve the chattr man page and clean up the chattr usage message.
148 E2fsck will now automatically fix a last mount time or last write time
149 which is in the future in preen mode, instead of aborting the fsck
152 Mke2fs will now check the file system revision number requested by the
153 command line, and reject it if it is too large. A file system with an
154 unsupported revision number will not be accepted by any of the other
155 file system tools, and this command line option is rarely used, so
156 let's try to help the user not shoot their own foot off.
158 The debugfs progam can now set the error count and associated
159 first_error and last_error fields in the superblock using the
160 set_super_value command.
162 Resize2fs will not try to calculate the minimum size of a file system
163 if it contains errors. Otherwise a very badly corrupted file system
164 image can cause the minimum size calculation to loop forwever. Since
165 resize2fs will not allow a file system marked as containing errors to
166 be resized. It's pointless to calculate the minimum size, so just
169 Fixed a typo in one of mke2fs's error message.
171 If filefrag runs into an error, it will continue processing the rest
172 of the files specified on thec ommand line, but then exit with an
175 Filefrag now prints some additional new flags (such as
176 FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
178 Fixed support in filefrag for files with > 2**32 blocks on 32-bit
181 Fixed a file descriptor leak in debugfs when copying files.
183 Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
184 to create file systems larger than 2GB on 32-bit platforms.
185 (Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
187 Add Esparanto and Ukrainian translations, and update Czech, Dutch,
188 French, German, Italian, Polish, Sweedish, and Vietnamese
191 Fixed various compiler warnings.
197 The gcc "-checker" option has been long deprecated, so remove support
198 from e2fsprogs. It was causing a few people to be confused when they
199 tried enabling the configure option.
201 Update to the latest version of the config.status and config.rpath
202 files, as well as newer versions of the autoconf files in aclocal.m4.
203 Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
204 people who want to use autoreconf to do so.
206 Make the use of strptime() function in debugfs to be more portable to
207 fix regression test failures for FreeBSD and MacOS.
209 A few miscellaneous changes designed to make life easier for
212 Fix the f_quota test and some Makefile dependencies if quota support
215 Fix cross-compilation support, which got broken in 1.42.10.
216 (Addresses Debian Bug: #753375)
218 Delete lib/ext2_types.h on a make clean, and build it as necessary.
220 Add a debug program used for libext2fs unit tests.
222 Clean up the tests so that it avoids using GNU-specific behaviour in
223 mktemp. Make sure the temporary files are cleaned up if the tests are
226 Add a new ext2fs_close_free() helper function which automatically
227 takes care of freeing the ext2_filsys structure even if ext2fs_close()
231 E2fsprogs 1.42.10 (May 18, 2014)
232 ================================
234 Mke2fs now creates file systems in regular files (which is very often
235 used when maintaining virtual machine images) without requiring the
236 user to use the force option. In addition, the mke2fs output has been
237 made much less verbose and only displays information that users will
238 be more likely to find useful by default.
240 Mke2fs now will ask the user to confirm that they want to continue
241 before wiping out a pre-existing file system, partition table, or LVM
244 Mke2fs now has the ability to create file systems where all the
245 metadata is located at the very beginning of the device. This can be
246 useful for flash devices which have SLC flash at the beginning of the
247 disk, for FAT compatibility, for example. As part of this, mke2fs and
248 tune2fs can control the location of the data blocks used by the
249 journal inode. In addition, the new sparse_super2 feature allows for
250 even fewer (anywhere from zero to two) backup superblocks.
252 Mke2fs now uses much less CPU when allocating the blocks used for very
255 Mke2fs can now support creating a file system at an offset. This can
256 be useful when creating a disk image for virtual machines (Addresses
259 Previously, e2fsck had a number of very serious bugs when checking a
260 file system wich used the new the quota file system option (where the
261 quota inodes were stored in hidden inodes) and the quota inode was
262 inconsistent with the actual usage data. This problem was documented
263 in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
264 been fixed in 1.42.10, so the quota should be safe to use with
267 Fixed in a bug in resize2fs which could cause shrink operation fail in
268 the unlikely situation when the inode table needs to be moved to a
269 location before the current location.
271 Resize2fs now has a much more accurate (and less conservative)
272 estimation of how far the file system can be shrunk. This allows a
273 mostly empty filesystem which is a few terabytes, to be shrunk to a
274 few megabytes in a single resize2fs -M operation.
276 E2fsck will now force a full file system check if there are any file
277 system inconsistencies detected in the super block.
279 The filefrag program will now display hte shared extent flag, which is
280 used by file systems such as btrfs.
282 If the number of inodes in the file systems is larger than the time
283 that file sytem was created (as measured by the number of seconds
284 since January 1, 1970) e2fsck would print a scary (but otherwise
285 harmless) warning of file system corruption for each inode in the
286 orphan list. This false positive has been fixed.
288 The e4defrag program has been fixed so it will no longer refuse with
289 filesystem with the 64-bit or the bigalloc feature enabled.
291 The logsave progam will print a much less scary message which could
292 lead users to believe something has gone very wrong with e2fsck exits
293 with a non-zero exit status (since this is normal after e2fsck has
294 automatically fixed a file system corruption during a preen
295 operation). (Addresses Debian Bug: #468821)
297 When creating a file system which is larger than 16TB, the
298 resize_inode option must be disabled -- since the resize_inode simply
299 doesn't support reserving metadata block numbers which is larger than
300 32 bits. The mke2fs program does this automatically if the file
301 system size is determined automatically. It will now also do this if
302 the file size is specified explicitly.
304 Fixed bugs associated with resize2fs and shrinking bigalloc file
307 The e2fsck program will no longer try to add a UUID on a mounted file
308 system with checksums enabled, since this could leave the file system
311 Tune2fs will allow the removal of an external journal from file system
312 which is marked as needing the journal replayed when the force ("-f")
313 option is given twice. (Addresses Debian Bug: #559301)
315 Tune2fs will no longer support enabling sparse_super if the meta_bg
316 file system feature is enabled, since it could result in data loss.
317 In practice, all modern file systems have sparse_super is enabled, so
318 it's not worth trying to change how tune2fs handles enabling the
319 sparse_super feature.
321 Fixed support for 1k block file systems with the meta_bg feature.
323 When the superblock is corrupt, e2fsck can't figure out the location
324 of the alternate superblock. Unfortunately, the routine that
325 calculates the location of the alternate superblock uses 8193 if it
326 can't figure this out, so the message printed by e2fsck always
327 suggests using "e2fsck -b 8193". This message has been fixed to
328 suggest both the superblock location of 8193 and and 32768.
329 (Addresses Debian Bug: #719185)
331 The lookback mount detection code that was introduced in 1.42.9 wasn't
332 actually compiled in due to an autoconf oops, so it's fixed now in
333 1.42.10. (Addresses Debian Bug: #497984)
335 A bug introduced in 1.42.9 would cause debugfs to print two error
336 messages if it found an error while parsing a user-supplied block
337 number. This has been fixed in 1.42.10.
339 Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
340 Vietnamese translations. (Addresses Debian Bug: #703048)
342 Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
345 Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
351 Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
353 Allow the location of pkg-config files to be specified independent of
354 the libdir location via a makefile variable.
356 Fixed parse-types.sh not to complain when cross-compiling and the
357 sizes of types are different between the target architecture and the
358 architecture of the build system
360 Allow the regression test suite to work correctly on systems which do
361 not have the "truncate" or "mksawp" programs.
363 Allow e2fsck to build correctly on systems (such as Android) that do
364 not have the signal.h file.
366 E2fsprogs now has code coverage testing which can be enbled using
367 "configure --enable-gcov".
369 The libe2p.h header file can now be used included by C++ programs.
371 The profile/config file used by e2fsck and mke2fs will interpret
372 numbers with a leading 0 character to mean that they should be
373 interpreted as an octal integer.
375 The extent handling functions in libext2fs have been improved so they
376 have proper rollback when there is an error splitting an extent. Also
377 fix a number of bugs when punching holes in files, and fix an
378 off-by-one bug when inserting an extent into an empty inode.
380 The libext2fs library now handles the support of BLOCK_UNINIT by
381 clearing the portion of block bitmap when it is loaded, instead of
382 when it is used. This reduces the chances of bugs, and and simplifies
383 the code. It also means that debugfs will properly show that blocks
384 in uninitialized block groups as being unused when using the testb
387 The e4defrag program will try to use fadvise64 or posix_fadvise64() if
388 it is present, which allows 64-bit offsets on 32-bit systems.
391 E2fsprogs 1.42.9 (December 28, 2013)
392 ====================================
394 Mke2fs will detect an attempt to create a file system on a loop
395 mounted file and complain without the -FF option. Also fixed mke2fs
396 so it allows the creation of a file system on a mounted device with
397 two -F options, as documented in the man page, instead of three -F
400 Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
401 libext2fs to correctly handle bigalloc and 64-bit file systems. There
402 were many corner cases that had not been noticed in previous uses of
403 these file systems, since they are not as common. Some of the bugs
404 could cause file system corruption or data loss, so users of 64-bit or
405 bigalloc file systems are strongly urged to upgrade to e2fsprogs
408 The tune2fs program will now not allow changing the uuid on a mounted
409 file system which has the uninit_bg feature enabled. This avoids a
410 nasty race where the kernel and tune2fs are both retrying rewrite the
411 group descriptors at the same time, with different ideas about what
414 When e2fsck is rehashing an extent-mapped directory, it's possible
415 (although very rare) that an extent block will need to be allocated;
416 fix e2fsck to make sure that the block gets marked as used.
418 Mke2fs will now properly set the LARGE_FILE feature when creating a
419 journal >= 2GB --- which can happen when using 64k block size.
421 Fixed debugfs so that its freei command will correctly handle a request
422 to free a range of consecutive inodes.
424 Fixed 2fsck so it will not erroneously complain that an external journal
425 is invalid if it is exactly 2**32 blocks.
427 Fixed e2fsck so it won't try checking for, and adding, a missing
428 lost+found directory when running in read-only mode.
430 Fixed e2image to avoid some buffer overruns which would cause it to when
431 creating a "standard (non-raw, non-qcow2) image file. Standard
432 e2image files are actually very rarely used, so we didn't notice when
433 the changes to enable the qcow2 format broke this e2image mode.
435 Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
436 on the resize_inode feature when the meta_bg feature is set, since
437 these two features can not be set at the same time.
439 Fixed tune2fs so that when it disables the quota feature, it updates all
440 of the backup superblocks.
442 Fixed dumpe2fs that would cause it to abort when run using an image file
443 when trying to print the journal information (which is not present in
444 an e2image created image file).
446 Fixed a potential integer overflow in e2reefrag.
447 (Addresses-Debian-Bug: #718205)
449 Enhance debugfs so that when copying a sparse file from a native file
450 system into the file system image using the "write" command, it will
451 create a sparse file into the destination file system.
453 Enhanced debugfs so it can support a command line which is up to 8k
456 E2image will refuse (unless the -f option is specified to force the
457 issue) to create a raw or qcow image using a mounted file system,
458 unless the -f option is specified to force the issue.
460 E2image has been optimized for using it to efficiently copy a file
461 system by only copying the allocated blocks, by using the options -ra.
462 New options (-o and -O) have been added so that a source and
463 destination offset can be given. The -p option will print progress
464 information so the user will know how far along the copy is going.
465 And finally, the new option -c is useful for updating a file system on
466 an SSD, by avoiding unnecessary writes. E2image can also shift a file
467 system image by doing an in place move.
469 Fix a regression introduced in 1.42.8 which would cause e2fsck to
470 erroneously report uninitialized extents past the EOF (as determined by
471 i_size) to be invalid.
473 Fixed resize2fs so under a corner case when an inode has a complex
474 extent tree, it will not corrupt an interior node in the extent tree.
476 Fixed resize2fs which would sometimes corrupt a file system when
477 shrinking a file system to a minimum size using resize2fs -M.
478 (Addresses Debian Bug: #660793)
480 Fixed resize2fs so that it will relocate inode table blocks if this
481 becomes necessary when shrinking the file system.
483 Fixed resize2fs and e2fsck so they will not crash when hit a failure
484 while operating on a file system with the MMP feature enabled.
486 Fixed a bug in debugfs which caused it create an invalid inode when
487 trying to write a zero-length file.
489 E2fsck will no longer crash if it tries to delete an invalid
490 extent-mapped symlink.
492 E2fsck will no longer crash if it comes across an directory which is
493 larger than 2GB (which is not allowed in valid file systems).
495 Fixed debugfs's help texts to fully document all options and otherwise
498 Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
501 Fixed various Debian Packaging Issues (#698879, #721365)
507 Fix sparse, gcc -Wall and clang nits.
509 Update config.{guess,sub} to the latest version
511 Fixed various memory and file descriptor leaks on various error paths,
512 as well as some missing error return checks, which were found using
515 Run sparse against source files when building e2fsprogs with 'make
516 C=1'. If instead C=2, it configures basic ext2 types for bitwise
517 checking with sparse, which can help find the (many many) spots where
518 conversion errors are (possibly) happening.
520 Allow the regression test to be run in chrooted environments where
521 /etc/mtab might be missing.
523 The ext2fs_punch() function, which was introduced in 1.42, was broken
524 in many ways, but this was never noticed since it wasn't used for
525 anything significant. Some of the bugs include failing when trying to
526 punch a completely sparse file, failing when punching an extent-mapped
527 inode when the starting block was at the beginning of the inode, and
528 not being able to punch a single block (where start_blk == end_block).
529 It also didn't handle being passed an invalid, too-large ending block
530 number, and didn't handle properly terminate at the right place when
531 operating on an indirect-mapped inode.
533 Fixed some minor typo's in the error catalog for libext2fs.
535 Fixed ext2fs_file_set_size2() so that if it truncates an inode by
536 setting the file size, to zero the rest of the block to the end of the
537 file, so that if an ext4 FUSE driver tries to extended the file, that
538 we don't avoid stale data from being returned.
540 Fixed ext2fs_bmap() to disallow clients from trying to map or set
541 logical blocks which are larger than what an extent-mapped or indirect
542 block-mapped inode can allow.
544 If debugfs (or some userspace program using libext2fs) creates a file
545 which is larger than 2GB, make sure the large_file feature flag gets
548 Fix a bug in ext2fs_link() where if there is multiple empty slots in the
549 directory which are large enough, the directory entry could get
550 inserted more than once in the directory.
552 If quota support is disabled (which is the default), make sure that
553 all traces of the quota support is removed from usage messages, man
554 pages, and tune2fs must not be able to enable the quota file system
555 feature. (Addresses Red Hat Bugzilla: #1010709)
557 The ext2fs_file_write() now updates i_size on a successful write,
558 instead of only updating i_size wen the file is closed via
561 Added a shell script, populate-extfs.sh which uses debugfs to populate
562 an ext2/3/4 file system image from a given directory. It is similar
563 to the genext2fs program, but it supports ext3 and ext4 file system.
565 Add changes to the libext2fs library to support block group
566 descriptors larger than 64 bytes (for future compatibility).
568 Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
569 leave an extra block in the file when truncating the file down to
572 The html version info pages are now built using makeinfo --html
573 instead of the unmaintained and now-obsolete texi2html program.
576 E2fsprogs 1.42.8 (June 20, 2013)
577 ================================
579 As a part of mke2fs's option parsing cleanup, the use of the -R option
580 will give a warning that it is depreated (it has been so documented
581 since 2005) and -E should be used instead.
583 Mke2fs will not give warnings about the bigalloc and quota options in
586 If an invalid journal size is given to mke2fs, it will now complain
589 Debugfs was erroneously giving spurious error messages for certain
590 extent_inode subcommands which take arguments (split_node,
591 replace_node, and insert_node). This has been fixed.
593 Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
594 other programs is used by mke2fs.
596 Change mke2fs so that it does not set the root directory to the real
597 uid/gid of the mke2fs process. Add the extended option root_owner to
598 override this behavior.
600 Fix resize2fs when shrinking file systems to make sure that bitmap
601 blocks aren't left outside the bounds of the shrunken file system.
602 This could happen with flex_bg file systems that were grown using
603 the old online resizing algorithm.
605 E2fsck will now detect and repair corrupted extent trees which contain
606 invalid extents at the end of the extent tree leaf block.
608 E2fsck will now longer complain about zero length extended attribute
611 Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
614 Add safety check so tune2fs will not attempt to set the inode size to
615 be larger than the block size.
617 Fix e2fsck so it can check a read-only root file system with an
618 external journal. (Addresses Debian Bug: #707030
620 Fix off-line resizing of file systems with flex_bg && !resize_inode
621 (Addresses Debian Bug: #696746)
623 Fix e2image with large (> 32-bit) file systems (Addresses Debian Bug:
626 Enhance chattr to allow clearing the extent flag if the kernel allows
627 migrating extent based files to use indirect blocks.

658 E2fsprogs 1.42.7 (January 21, 2013)
659 ===================================
661 Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
662 quota features are still under development. For more information
664 * https://ext4.wiki.kernel.org/index.php/Bigalloc
665 * https://ext4.wiki.kernel.org/index.php/Quota
667 Add some new options to filefrag from Lustre's patches to e2fsprogs:
668 * add -k option to print extents in kB-sized units (like df -k)
669 * add -b {blocksize} to print extents in blocksize units
670 * add -e option to print extent format, even when FIBMAP is used
671 * add -X option to print extents in hexadecimal format
673 Fix resize2fs so that it can handle off-line resizes of file systems
674 with the flex_bg feature but without a resize_inode (or if we run out
675 of reserved gdt blocks). This also fixes a problem where if the user
676 creates a filesystem with a restricted number of reserved gdt blocks,
677 an off-line resize which grows the file system could potentially
678 result in file system corruption.
680 Fix a resize2fs bug which could cause it to corrupt bigalloc file
681 systems when doing an off-line resize.
683 Further optimize resize2fs so it doesn't use quite as much CPU when
684 resizing very large file systems.
686 Fixed 32-bit overflow bugs which could cause resize2fs to fail and
687 possibly corrupt the file system while resizing 64-bit file systems.
689 Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
690 mke2fs crash due to a divide-by-zero if the 64bit file system feature
693 Add better error checking to mke2fs to check for invalid parameters
694 when creating bigalloc file system.
696 When creating bigalloc filesystems, the -g option to mke2fs will now
697 specify the number of clusters per block group.
699 Add to debugfs the functionality to corrupt a specific file system
700 block via the "zap_block" command.
702 Add to debugfs the functionality to print out a hex dump of a block in
703 the file system via the "block_dump" command.
705 Add to debugfs the functionality to manipulate the extent tree
706 directly via the "extent_open" command.
708 Fixed debugfs's mknod command so that it updates the block group
711 Fix e2fsck so it can detect and fix inconsistencies in the interior
712 nodes of an inode's extent tree.
714 Fix a potential memory corruption failure in e2fsck's error path if
715 the call to ext2fs_open2() fails.
717 Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
718 resulting file name for the log file is longer than 100 bytes, that it
719 properly handles this situation instead of crashing.
721 E2fsck will now report the amount of memory that it attempted to
722 allocate when a memory allocation request fails, to make it easier to
723 track down the problem.
725 Fix mke2fs's handling of the mmp_update_interval option. (Addresses
728 E2image can now include all data blocks in the e2image output file
729 when the user specifies the -a option.
731 If e2fsprogs is compiled without --enable-quota, make sure that
732 tune2fs can not turn on the feature for new-style quota support, since
733 afterwards, none of the e2fsprogs tools will be willing to touch that
736 Optimize e2fsck's so that it uses much less CPU for large file
737 systems. This can result in significant speedups, especially on
738 CPU-constrained systems. This was primarily done by optimizing
739 libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
741 Fix debugfs's htree command so that all its messages are sent through
744 Fixed debugfs's "dump_file" and "cat" functions work correctly
745 on file systems whose block size is greater than 8k.
747 Fix e2freefrag so it works on 64-bit file systems, and so it uses much
748 less memory. (Addresses Google Bug: 7269948)
750 Update the spd_readdir.c file in the contrib directory to include some
751 additions which were made in 2008 that didn't get folded into the
752 version which we checked into the e2fsprogs source tree. These
753 enhancements include thread safety, support for readdir64_r(), and
754 safe_getenv() support in case spd_readdir.so is used for setuid binaries.
756 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
759 Add a command to debugfs to create symlinks.
761 Document the bigalloc feature in the mke2fs man page. (Addresses
770 Fix a spelling typo in the libext2fs texinfo documentation.
772 Change the output from "make check" so that tools such as emacs's "M-x
773 compile" does not mistake the output as containing a compiler error.
775 Export two new functions from libext2fs: ext2fs_extent_node_split()
776 and ext2fs_extent_goto2().
778 The ext2fs_extents_fix_parents() was fixed so it does not modify the
779 location of the extent handle if its current location is at an
780 interior node, rather than a leaf node of an inode's extent tree.
782 Add a regression test to assure that e2fsck can correctly fix an
783 inconsistent interior node in an inode's extent tree.
785 The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
786 correctly support bigalloc file systems which use store block usage
787 information in units of clusters.
789 Fixed the help text in the configure script for --enable-quota.
791 The m68k-specific bitops code has been removed since they were
792 incorrectly treating bit numbers with the high bit set as signed
793 integers. Furthermore, modern compilers do a good enough job
794 optimizing the generic code there is no point in having the m68k
795 specific asm statements.
797 Fixed how we link the test programs so they always use the static
798 libraries, so that we test using the libraries which we have just
801 Update config.guess and config.sub to the latest versions from the GNU
804 Fixed the com_err.texinfo file so that it can produce a valid
805 postscript/pdf printed output.
807 Add a regression test which checks debugfs's ability to create
808 symlinks, named FIFO's, and device nodes.
810 Add a function ext2fs_symlink(), which creates symlinks to the
813 Add debugging code so we can test old kernel interfaces for online
814 resize to resize2fs. This backwards compatibility checking is keyed
815 off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
816 test the functionality of the kernel's older resize ioctls without
817 needing to install an old version of resize2fs, and to also test a
818 modern resize2fs's ability to work with older kernels without having
819 to install an older version of the kernel.
822 E2fsprogs 1.42.6 (September 21, 2012)
823 =====================================
825 When mke2fs creates file systems with lazy itable initialization, the
826 progress updates for writing the inode table happens so quickly that
827 on a serial console, the time to write the progress updates can be the
828 bottleneck. So mke2fs will now only update its progress indicators
831 Resize2fs will skip initializing the inode tables if the kernel
832 supports lazy_itable_init, which speeds up growing off-line growth of
833 uninit_bg file systems significantly. Resize2fs will now also
834 correctly set the itable_unused field in the block group descriptor to
835 speed up the first e2fsck after the file system is grown.
837 Resize2fs has been fixed so that on-line resizing of meta_bg file
838 systems work correctly. This is needed to grow file system which are
841 Resize2fs will now correctly handle resizing file systems to 16TB on
842 32-bit file systems when "16TB" is specified on the command line.
844 Fix mke2fs so that it will be careful to set the reserved blocks ratio
845 larger than 50%; this can happen when creating small file systems and
846 when the last block group is dropped because there are not enough
847 blocks to support the metadata blocks in the last block group.
849 Fixed spelling mistake in debugfs's help message.
851 Fixed a potential seg fault in e2fsck when there is an I/O error while
852 reading the superblock.
854 Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
856 Updated/fixed various man pages. (Addresses Sourceforge Bug:
862 The configure option --enable-relative-symlink was broken so that it
863 needed to be --enable-symlink-relative-symlinks. We will support both

867 Fixed a regression introduced in 1.42.5 so the link order for
868 e2fsprogs' libraries will be correct for both static and shared
869 linking. (Addresses Sourceforge Bug: #3554345)
871 Add support for e2fsprogs to be compiled using clang/LLVM.

881 E2fsprogs 1.42.5 (July 29, 2012)
882 ================================
884 Fixed a bug with mke2fs where if there is only 8 inodes per block
885 group, the calculation of the number of uninitialized inodes in the
886 first block group would go negative. This resulted in "mke2fs -N 256
887 -t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
888 would run out of space. (Addresses Sourceforge Bug: #3528892)
890 Fixed a bug in how e2fsck would uniquify directory entry names.
891 (AddressesSourceforge Bug: #3540545)
893 Previously, e2fsck would only allow a mounted file system to be
894 checked if it was the root file system and it was mounted read-only.
895 Now it will allow any file system mounted read-only to be checked if
896 the -f option is specified. This makes it easier to test how e2fsck
897 handles checking file systems which are mounted without having to test
898 on the root file system.
900 Fixed a problem if e2fsck where if the root file system is mounted
901 read-only, e2fsck would not clear an error indication in the journal
902 superblock. Combined with a kernel bug, this would cause the e2fsck
903 to check the file system after every single boot.
905 The e4defrag program can now handle device symlinks, such as
906 /dev/mapper/testvg-testlv, instead of insisting on a less
907 human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
910 Fixed filefrag so it will not crash with a segfault on files from a
911 virtual file system such as /proc. (e.g., "filefrag
914 Fixed filefrag so that it correctly reports the number of extents.
915 (Addresses Red Hat Bugzilla: #840848)
917 Fixed a file descriptor leak in logsave which could cause it to hang.
918 (Addresses Debian Bug: #682592)
920 Fixed e2fsck so that the file system is marked as containing an error
921 if the user chooses not to fix the quota usage information.
923 Fixed tune2fs so that it correctly removes the quota feature when the
924 last quota inode is removed.
926 Fix tune2fs so that after removing a quota inode, the block bitmap is
927 updated; otherwise, e2fsck would complain after running 'tune2fs -O
930 Fix tune2fs so that when converting a file system from using legacy
931 quota files to the new quota file system feature with hidden quota
932 files, the accounting for these files is handled correctly so that
933 e2fsck doesn't complain.
935 Improved e2fsck's verbose reporting statistics, and allow the more
936 verbose reporting to be enabled via /etc/e2fsck.conf.
938 Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
940 Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
946 Fixed portability problems on other operating systems (e.g., Hurd and
947 FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
949 Make sure that shared libraries link with the shared libraries built
950 in the build tree, instead of the system provided libraries.
951 Previously, libraries and executables were linked with the system
952 libraries if present, and possibly using static archives instead of
953 shared libraries. This was also problematic since if libext2fs.so is
954 linked with a static libcom_err.a from system, the build system would
955 attempt to link without -lpthread. (Addresses Sourceforge Bug:
959 E2fsprogs 1.42.4 (June 12, 2012)
960 ================================
962 Fixed more 64-bit block number bugs (which could end up corrupting
963 file systems!) in e2fsck, debugfs, and libext2fs.
965 Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
966 not properly propagating the journal's s_errno field to the superblock
967 field; it was not checking this field if the journal had already been
968 replayed, and if the journal *was* being replayed, the "error bit"
969 wasn't getting flushed out to disk.
971 Fixed a false positive complaint by e2fsck if all of the extents in
972 the last extent tree block are uninitalized and located after the end
973 of the file as defined by i_size.
975 The dumpe2fs will now display the journal's s_errno field if it is
976 non-zero, and it will also display the journal's 64-bit feature flag
979 Fix e2fsck so that it always opens the device file in exclusive mode
980 when it might need to modify the file system, and never if the -n
981 option is specified. (Previously, there were a few corner cases where
982 it might get things wrong in either direction.)
984 E2fsck now correctly truncates or deallocates extent-mapped inodes on
985 the orphan list. The root cause was a bug in libext2fs's block
986 iterator which could end up skipping an extent when the last block in
987 an extent is removed, causing the current extent to be removed from
990 E2fsck now correctly sets the global free block and inode counts when
991 truncating or removing inodes on the orphan list in preen mode.
992 Previously, it would leave these values would be set incorrectly,
993 which is largely a cosmetic issue since the kernel no longer pays
994 attention to those fields, but it can cause spurious complaints in
995 subsequent e2fsck runs.
997 Fix i_blocks accounting when the libext2fs library needs to add or
998 remove an extent tree block on bigalloc file systems.
1000 The lsattr and chattr programs now support the No_COW flag for the
1003 Debugfs now interprets date strings of the form @ddd as ddd seconds
1004 after the beginning of the epoch. This is handy when setting an inode
1005 number into the d_time field when debugging orphan list handling.
1007 Fix a precedence bug with built-in quota support which might result in
1008 e2fsck paying attention to the quota inode field even if the built-in
1009 quota feature flag is not set. Fortunately, in practice that
1010 superblock field should be zero for non-built-in quota file systems,
1011 so it's unlikely this bug would have caused problems.
1013 Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
1019 The regression test suite can now run the integration tests in the
1020 tests directory in parallel, via "make -jN check".
1022 Add new test, f_zero_extent_length which tests e2fsck's handling of
1023 the case where all of the extents in the last extent tree block are
1024 uninitialized extents after i_size.
1026 Add a new test, f_jnl_errno, which checks handling of an error
1027 indication set in the journal superblock.
1029 Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
1030 of a 64-bit journal.
1032 Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
1033 tests e2fsck's handling of orphan inodes in preen mode, and truncation
1034 of extent inodes on the orphan list.
1036 Fixed more OS X portability issues.
1039 E2fsprogs 1.42.3 (May 14, 2012)
1040 ===============================
1042 Fix a bug in the Unix I/O manager which could cause corruption of file
1043 systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
1044 (i.e., when unsigned long is 32-bits). Also fix a bug which caused
1045 dumpe2fs to incorrectly display block numbers > 32-bits.
1047 Improve the support for integrated quota files (where quota is a first
1048 class supported feature using hidden files in the ext4 file system).
1049 Previously the quota file was getting rewritten even when it was not
1050 necessary, and e2fsck would erroneously try to hide quota files which
1051 were already hidden.
1053 Quiet complaints in e2fsck when the total free blocks or inodes are
1054 incorrect in the superblock after an system crash, since we don't
1055 update nor depend on the superblock summaries at each commit boundary.
1057 Fixed a regression introduced in 1.42.2 which would cause applications
1058 outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
1059 would were still using the legacy 32-bit bitmaps) to crash. This was
1060 due to missing 32-bit compat code in side the function
1061 ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
1064 Fix a bug which would cause mke2fs to fail creating the journal if
1065 /etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
1068 Updated/fixed various man pages.
1070 Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
1073 Fixed various Debian Packaging issues.
1079 Change the nonsensically wrong types in the function signature of the
1080 inline function ext2fs_find_first_zero_block_bitmap2(). This was
1081 caused by a cut and paste error; fortunately no code in e2fsprogs used
1082 this inline function, and there are any users of this functions
1083 outside of e2fsprogs.
1085 Add support for systems which have valloc(), but which do have
1086 posix_memalign() nor memalign() (such as MacOS 10.5).
1088 Refactor and clean up the allocation of aligned buffers for Direct I/O
1089 support. Previously some allocations were requesting a greater
1090 alignment factor that what was strictly necessary. Also optimize
1091 reading and writing bitmaps using Direct I/O when the size of the
1092 bitmap did not fully cover the file system blocksize.
1094 Reserve the codepoints for the INCOMPAT features LARGEDATA and
1097 Improved the regression test suite by adding some new integration
1098 tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
1099 jbd2 format, as well as f_eofblocks which tests the new handling of
1100 uninitialized and initialized blocks beyond i_size. Also add a new
1101 unit test which verifies 32-bit bitmaps support and the new
1102 find_first_zero primitives.
1104 Add a few dependencies to fix parallel (make -j) builds.
1106 Removed bash'isms which were breaking the regression test suite on
1107 systems where /bin/sh is not bash.
1109 The config.guess and config.sub have been updated to the 2012-02-10
1112 Fix a portability problem caused by assuming the present of mntent.h
1113 means that setmntent() exists. Instead, explicitly test for this in
1114 the configure script.
1116 If the sys/signal.h header file does not exist, don't try to include
1117 it, since it's not available on all systems.
1119 Add support for systems that do not support getpwuid_r()
1121 The configure script now supports a new option,
1122 --enable-relative-symlinks, which will install relative symlinks for
1123 the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
1125 When building BSD shared libraries make sure the LDFLAGS variable is
1126 passed to the linker. Fixing this allows, for example, e2fsprogs to
1127 be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
1130 Fix gcc -Wall nitpicks
1133 E2fsprogs 1.42.2 (March 27, 2012)
1134 =================================
1136 The resize2fs program uses much less CPU and is much faster for very
1137 large file systems. (Addresses Debian Bug: #663237)
1139 The seti and freei commands in debugfs can now take an optional length
1140 argument to set and clear a contiguous range of inodes.
1142 E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
1143 plan to remove support for it from the kernel file system driver. It
1144 really wasn't very useful and was causing more problems than it
1145 solves. Since e2fsck will complain if inodes that should have
1146 EOFBLOCKS_FL do not have the flag set, we are going to remove this
1147 check from e2fsprogs first, and then only remove the flag from the
1150 The mke2fs program can now use direct I/O via "mke2fs -D". This will
1151 slow down the mke2fs, but it makes it more polite on a loaded server
1152 by limiting the amount of memory that gets dirtied by mke2fs when it
1153 is using buffered I/O.
1155 E2fsck was needlessly closing and re-opening the file system as a side
1156 effect of adding Multiple Mount Protection (MMP). This isn't
1157 necessary for non-MMP file systems, so drop it.
1159 Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
1160 can more easily diagnose memory allocation failures caused by
1161 insufficient memory. E2fsck will now abort if there are memory
1162 allocation failures when the file system is initially opened and
1163 during the block group descriptor checks. (Addresses Google Bug:
1166 If there are incorrect block group checks, e2fsck will now report the
1167 incorrect and corrected checksum values.
1169 The e2fsck progam can now write log files containing the details of
1170 the problems that were found and fixed directly, via configuration
1171 parameters in /etc/e2fsck.conf.
1173 Added the ability to limit the number of messages reported by e2fsck
1174 for a given problem type. This avoids a potential bottleneck if there
1175 is a serial console which can cause a boot sequence to take a long
1176 time if e2fsck needs to report many, many file system errors.
1178 The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
1179 them to use much less memory for large file systems.
1181 The dumpe2fs program will now print the expected block group checksum
1182 if it is incorrect. This helps to diagnose problems caused by
1183 incorrect block group checksums.
1185 E2fsck now checks for extents with a zero length, since the kernel
1186 will oops if it comes accross such a corrupted data structure. (See
1187 https://bugzilla.kernel.org/show_bug.cgi?id=42859)
1189 E2fsck has a number of bugs relating to discard that have been fixed.
1190 (1) Fixed a bug which could cause e2fsck to discard portions of the
1191 inode table which were actually in use. (2) E2fsck will now avoid
1192 using discard if the block device doesn't zero data on discard, since
1193 otherwise this could cause problems if the file system gets corrupted
1194 in the future. (3) E2fsck will now avoid using discard when it is run
1195 in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
1196 discards in the last block group.
1198 E2fsck's CPU utilization in pass 5 has been optimized, which will
1199 speed up e2fsck slightly.
1201 E2image will now skip copying uninitialized bitmap and inode table
1204 Fixed mke2fs -S so it does not corrupt the first block group's
1207 E2fsck will now check the new sysfs interface to determine if we are
1208 using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
1210 Updated/fixed various man pages. (Addresses Debian Bug: #665427)
1212 Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
1217 Fixed various portability issues for non-Linux systems, particularly
1218 MacOS X, as well as Linux systems running with the just-released glibc
1221 Fix file descriptor leak in ext2fs_close() if the file system with
1222 uninit_bg is opened read/only with a backup superblock. (Addresses
1223 SourceForge Bug: #3444351)
1225 Fixed an invalid return in a non-void function in the quota code.
1226 (Addresses SourceForge Bug: #3468423)
1228 Fixed the debian rules file so that the calls to dpkg-buildflags works
1229 when the shell is dash.
1231 The debian package build now uses V=1 so that there is more
1232 information about potential build failures in debian buildd logs.
1234 If the uninit flags get cleared by functions such as
1235 ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
1236 superblock is marked dirty and the block group descriptor checksum is
1237 updated if necessary.
1239 The debian rules file will now try to load debian/rules.custom of it
1240 exists. This flie can skip various builds for speed reasons if there
1241 is no need for the e2fsck-static or udeb packages. Available
1242 customizations in the rules file includes SKIP_STATIC=yes,
1243 SKIP_BF=yes, and SKIP_DIETLIBC=yes.
1245 In addition, if the file misc/mke2fs.conf.custom.in exists in the
1246 source tree, it will be used instead of the standard misc.conf file in
1247 the upstream sources. This makes it easier for Debian-derived systems
1248 to distribute a custom mke2fs.conf file without having to worry about
1249 merge issues if future versions of e2fsprogs makes changes in the
1250 upstream default version of mke2fs.conf.
1253 E2fsprogs 1.42.1 (February 17, 2012)
1254 ===================================
1256 The mke2fs and e2fsck now use significantly less memory when creating
1257 or checking very large file systems. This was enabled by adding
1258 extent-based bitmaps which are stored using a red-block tree, since
1259 block and inode allocations tend to be contiguous.
1261 The command mke2fs -S is used as a last ditch recovery command to
1262 write new superblock and block group descriptors, but _not_ to destroy
1263 the inode table in hopes of recovering from a badly corrupted file
1264 system. So if the uninit_bg feature is enabled, mke2fs -S will now
1265 set the unused inodes count field to zero. Otherwise, e2fsck -fy
1266 after using mke2fs -S would leave the file system completely empty.
1268 Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
1269 honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
1270 installed an mke2fs binary using that name.
1272 The usage and help messages for the -G, -t and -T options in mke2fs
1275 If e2fsck needs to use the backup group descriptors, the
1276 ext2fs_open2() function clears the UNINIT bits to ensure all of the
1277 inodes in the file systems get scanned. However, the code which reset
1278 the UNINIT flags did not also recalculate the checksum, which produced
1279 many spurious (and scary) e2fsck messages. This has been fixed by
1280 resetting cheksums when the UNINIT bits are cleared.
1282 Relax a check in e2fsck which required that the block bitmap to be
1283 initialized when the inode bitmap is in use. This will allow us to
1284 eventually eliminate code from the kernel which forcibly initialized
1285 the block bitmap when the inode bitmap is first used, requiring an
1286 extra journal credit and disk write. (Addresses Google Bug: #5944440)
1288 Make sure rdebugfs (which may be installed setuid or setgid disk) does
1289 not honor environment variables if euid != uid or egid != gid.
1291 Debugfs's ncheck command has been optimized and now is much more
1292 robust with faced with corrupted file systems. The ncheck command
1293 also now has a -c option which will verify the file type information
1294 in the directory entry to see if matches the inode's mode bits. This
1295 is extremely useful when trying to use debugsfs to determine which
1296 parts of the file system metadata can be trusted.
1298 E2image will try to use ftruncate64() to set the i_size for raw
1299 images, instead of writing a single null byte. This avoid allocating
1300 an extra block to the raw image, for those file systems and/or
1301 operating systems that support this. (Linux does.) In addition, fix
1302 a logic bug that caused the file to not be properly extended if the
1303 size of the last hole was exactly an multiple of a megabyte.
1305 Fixed a bug in resize2fs where for 1k and 2k file systems, where
1306 s_first_data_block is non-zero, this wasn't taken into account when
1307 calculate the minimum file system size for use with the -M option.
1309 Fixed the badblocks program to honor the -s flag when in read-only -t
1310 mode. (Addresses Debian Bug #646629)
1312 Update Czech, Dutch, French, Polish, and Sweedish translation from the
1313 Translation Project.
1315 Fixed various Debian Packaging issues so that dpkg-buildflags is used
1316 if present, which allows e2fsprogs to be built with security hardening
1317 flags. (Addresses Debian Bugs: #654457)
1322 Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
1323 This was only an issue for programs compiled against e2fsprogs 1.41
1324 that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
1327 The libext2fs library now uses sysconf() to fetch the page size, instead
1328 of the deprecated getpagesize().
1330 The ext2fs_get_pathname() function will return a partial path if an a
1331 directory in the path is not a directory, displaying it as an inode
1332 number in angle brackets instead of giving up and displaying an error.
1333 This is much more helpful when a user is trying to debug a corrupted
1336 Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
1338 Added a new library function, ext2fs_file_get_inode_num(), for use by
1341 Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
1342 file, it actually works.
1344 The block iterator now properly honors the BLOCK_ABORT flag for
1345 extent-based flags. Previously, it didn't, which generally made code
1346 be less efficient, but it could cause bugs in ext2fs_link(), for
1347 example, by causing it to insert multiple directory entries.
1349 Fixed an (harmless other than causing a compiler warning) use of an
1350 uninitialized variable in e2fsck's MMP code.
1353 E2fsprogs 1.42 (November 29, 2011)
1354 ==================================
1356 This release of e2fsprogs has support for file systems > 16TB. Online
1357 resize requires kernel support which will hopefully be in Linux
1358 version 3.2. Offline support is not yet available for > 16TB file
1359 systems, but will be coming.
1361 This release of e2fsprogs has support for clustered allocation. This
1362 reduces the number of block (now cluster) bitmaps by allocating and
1363 deallocating space in contiguous power-of-2 collections of blocks,
1364 which are called clustered. This is a file system level feature,
1365 called 'bigalloc', which must be enabled when the file system is
1366 initially formatted. It is not backwards compatible with older
1369 Added support for the Multi-Mount Protection (MMP) feature.
1371 E2fsck more efficiently uses scratch files for really big file
1372 systems. (This is a feature that has to be turned on explicitly; see
1373 [scratch_files] in the e2fsck.conf man page.)
1375 Fix a bug in e2fsck where if the free blocks and inodes counts are
1376 incorrect, e2fsck would fix them without printing an error message.
1377 This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
1378 any explanation of what was fixed.
1380 E2fsck will no longer attempt to clone an extended attribute block in
1381 pass1b handling if the file system does not support extended
1384 E2fsck will be more careful accidentally asking the user to continue
1385 if the file system is mounted, so that an escape sequence won't cause
1386 a false positive. (Addresses Debian Bug: #619859)
1388 E2fsck now uses less cpu time in pass 5 when large portions of the
1389 bitmaps are uninitialized.
1391 E2fsck will no longer segault when a corrupted file system has a bad
1392 extent, and removing it leads to a block needing to be deallocated.
1393 (Addresses SourceForge Bug: #2971800)
1395 E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
1396 and print debugging information to make it easier to find potential
1399 E2fsck will check to see if the bad block inode looks insane, and will
1400 skip trying to use if it certain fields which should be zero look
1401 non-zero. This is to avoid a corrupted bad block inode causing e2fsck
1402 to get confused and do more harm than good.
1404 If e2fsck modifies certain superblock fields which the kernel doesn't
1405 look at, it will now mark the superblock as dirty without marking the
1406 file system as changed. This avoids signalling the init scripts that
1407 a reboot is necessary, since the kernel isn't going to look at those
1408 fields, so it won't care if they have been changed.
1410 Fixed a bug in the libext2fs library (in the binary search routine of
1411 the icount abstraction) that could (very, very rarely) cause e2fsck to
1412 die in the middle of pass 1 or pass 2 processing.
1414 E2fsck will not try to do a discard operation if the -n option was
1415 specified on the command line.
1417 E2fsck now supports an extended "discard" option which will cause
1418 e2fsck to attempt discard all unused blocks after a full, successful
1421 E2fsck will check for the bad block inode to make sure it looks sane
1422 before trusting it, to avoid causing more harm than good to the file
1425 E2fsck now returns additional status bits in its exit code if it
1426 aborts early in the e2fsck run.
1428 E2fsck now correctly calculates the maximum file size in the case of
1429 the huge_file file system feature enabled without extents.
1431 The mke2fs and e2fsck programs now tries to use the punch hole command
1432 as a "discard" when operating on normal files.
1434 The e2image program now supports the qcow2 format, which is a more
1435 efficient way of capturing file system dumps.
1437 Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
1438 per-device defaults to be specified in the configuration file.
1440 Mke2fs now supports the reserved_ratio relation in the [defaults] and
1441 [fs_types] section in mke2fs.conf.
1443 Mke2fs now creates extent-mapped directories for the root and
1444 lost+found directories.
1446 Mke2fs will skip zero'ing the journal if the extended option
1447 "lazy_journal_init" is specified. This can save a lot of time, but it
1448 does add a small amount of risk if the system crashes before the
1449 journal is overwritten entirely once. It is epsecially useful for
1452 Mke2fs will now create file systems that enable user namespace
1453 extended attributes and with time- and mount count-based file
1454 system checks disabled.
1456 Mke2fs will not set a stride or strip size of one block based on block
1457 device attributes obtained from sysfs.
1459 Mke2fs now displays a progress report during the discard process.
1461 Mke2fs now handles extreme file system parameters correctly which
1462 previously caused the inodes per group to drop below 8, leading to a
1463 segfault. (The inodes per group must be a multiple of 8, but the code
1464 didn't correctly deal with an inodes per group count less than 8.)
1466 Mke2fs and tune2fs previously would give an error if the user tried
1467 setting the stride and stripe-width parameters to zero; but this is
1468 necessary to disable the stride and stripe-width settings. So allow
1469 setting these superblock fields to zero. (Addresses Google Bug:
1472 Mke2fs now gives a warning if the auto-detected block size exceeds the
1475 If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
1476 is the default), mke2fs will now set the s_max_mnt_count superblock
1477 field to -1, instead of 0. Kernels older then 3.0 will print a
1478 spurious message on each mount then they see a s_max_mnt_count set to
1479 0, which will annoy users. (Addresses Debian Bug: #632637)
1481 The default mke2fs.conf now has entries for "big" and "huge", which
1482 are needed for very big file systems.
1484 The resize2fs program now has support for a new online resize ioctl
1485 that can support file systems > 16TB, once it arrives in v3.x kernels.
1487 Fixed bug which caused resize2fs to fail when shrinking an empty file
1488 system down to its minimal size. (Addresses Sourceforge Bug #3404051)
1490 Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
1492 Allow tune2fs to remove external journals if the device can not be
1495 Debugfs's icheck will now correctly find inodes which use the
1496 searched-for block as an extended attribute block.
1498 Debugfs now has a new "punch" command which remove blocks from the
1501 Debugfs now has a new "e2freefrag" command which analyzes the free
1502 space fragmentation of the file system, using the same code as the
1505 Debugfs now has a "filefrag" command which displays information about
1506 a file's fragmentation.
1508 Add support to build a metadata-only, read-only, stripped-down version
1509 of debugfs called rdebugfs.
1511 Fixed a potential stack overrun bug in debugfs.
1513 The badblocks program now correctly recovers from I/O errors when
1514 direct I/O is being used. The badblocks command now also supports a
1515 -B option which forces the use of buffered I/O, and the -v option will
1516 provide a more detailed breakdown of read, write, and failed
1519 Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
1521 Added support for journals larger than 2GB.
1523 Support using both hard links and symlinks when installing e2fsprogs.
1525 Add overflow checking to tune2fs -i's fsck interval, which must fit in
1528 The debugfs command now has a new 'blocks' command which prints out
1529 data blocks of a particular inode in a format which is useful for
1532 Filefrag will report 0 extents correctly in verbose mode. (Addresses
1533 RedHat Bugzilla: #653234)
1535 Filefrag has been fixed so its -v report prints the correct expected
1536 block number (previously there had been an off-by-one error). In
1537 addition, it will now display the number of contiguous extents when -v
1538 is not specified. This makes it consistent with the number of extents
1539 printed when the -v option was specified. In addition, the number of
1540 contiguous extents is far more interesting/useful than the number of
1541 physical extents for very large files. (Addresses Debian Bug:
1544 Logsave's usage message has been fixed. (Addresses Debian Bug:
1547 Avoid an infinite loop in ext2fs_find_block_device() if there are
1548 symlink loops in /dev caused by a buggy udev.
1550 Added a useful "fallocate" program to the contrib directory.
1552 Fixed an ABI compatibility problem in libext2fs which broke the dump
1553 program. Also added back some macros which dump needed so it could
1554 compile against the latest version of ext2_fs.h (Addresses Debian Bug:
1557 Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
1558 Debian Bug: #641667)
1560 Added internationalization support for libcom_err error table strings.
1562 Fixed various spelling mistakes found in various output strings found
1563 by I18N translators.
1565 Update translations: French, Chinese, Germany, Indonesian, Swedish,
1566 Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
1569 Fixed various Debian Packaging issues. (Addresses Debian Bugs:
1570 #614662, #632169, #641838, #627535, #629355)
1572 Updated/clarified man pages. (Addresses Debian Bugs: #639411,
1578 Initial support for quota as an integrated feature, where the quota
1579 files are hidden system files that are automatically maintained by
1580 e2fsck is present, although disabled by default. It must be enabled
1581 by using the configure option --enable-quota.
1583 Reserved the on-disk fields for the metadata checksum and snapshot
1584 features, which are currently in development.
1586 The ext2fs library now has the new functions ext2fs_punch(),
1587 ext2fs_get_memzero() and ext2fs_file_get_inode().
1589 The ext2fs library now has support for calculating the crc32c checksum
1590 (via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
1592 The I/O manager now supports the discard operation.
1594 Reserved file system code points for new 1st class quota feature.
1596 Shortened the compilation lines by moving the autoconf defines to
1597 a config.h header file.
1599 Fixed a potential free of an unitialized pointer in
1600 ext2fs_update_bb_inode().
1602 Fixed miscellaneous gcc -Wall and coverity warnings.
1604 Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
1606 Fixed a build failure when OMIT_COM_ERR is defined.
1608 Improved error checking and fixed memory leaks caused by error return
1611 Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
1612 the fsync() to be skipped.
1614 Added a test for extent-mapped journals by mke2fs and tune2fs.
1616 Added a test for creating a large (over 4GB) journal using mke2fs.
1618 Added a test to make sure the inode size remains constant.
1620 The regression test script now prints the list of which tests failed.
1622 The regression test system now uses /tmp for its scratch files, which
1623 is often a tmpfs mounted file system and hence much faster.
1625 The i_e2image test was fixed so it works with valgrind.
1627 Tests that rely on debugfs are now skipped if debugfs wasn't built.
1629 Fixed the dependencies for "make check" so all required dependencies
1630 are built before running the gression tests.
1632 A link to com_err.h is installed in $(includedir) during a "make install".
1634 The po/*.gmo files are automatically rebuilt if they are missing or
1635 out of date. This helps out Debian packaging.
1637 Allow ext2fs_get_memalign() to compile on systems that don't have
1640 Fixed a namespace leak in libext2fs (tdb_null).
1643 E2fsprogs 1.41.14 (December 22, 2010)
1644 =====================================
1646 Fix spurious complaint in mke2fs where it would complain if the file
1647 system type "default" is not defined in mke2fs.conf.
1649 The resize2fs program will no longer clear the resize_inode feature
1650 when the number reserved group descriptor blocks reaches zero. This
1651 allows for subsequent shrinks of the file system to work cleanly for
1652 flex_bg file systems.
1654 The resize2fs program now handles devices which are exactly 16T;
1655 previously it would give an error saying that the file system was too
1658 E2fsck (and the libext2fs library) will not use the extended rec_len
1659 encoding for file systems whose block size is less than 64k, for
1660 consistency with the kernel.
1665 E2fsprogs 1.41.13 would not compile on big-endian systems. This has
1666 been fixed. (Addresses Sourceforge Bug: #3138115)
1668 The ext2fs_block_iterator2() function passed an incorrect ref_offset
1669 to its callback function in the case of sparse files. (Addresses
1670 Sourceforge Bug: #3081087)
1672 Fix some type-punning warnings generated by newer versions of gcc.
1675 E2fsprogs 1.41.13 (December 13, 2010)
1676 =====================================
1678 E2fsck now supports the extended option "-E journal_only", which
1679 causes it to only do a journal replay. This is useful for scripts
1680 that want to first replay the journal and then check to see if it
1683 E2fsck will now support UUID= and LABEL= specifiers for the -j option
1684 (which specifies where to find the external journal). (Addresses
1687 E2fsck now has support for the problems/<problem code>/force_no
1688 configuration option in e2fsck.conf, which forces a problem to not be
1691 Dumpe2fs will now avoid printing large negative offsets for the bitmap
1692 blocks and instead print a message which is a bit more helpful for
1693 flex_bg file systems.
1695 Mke2fs will now check the file system type (specified with the -t
1696 option) to make sure it is defined in the mke2fs.conf file; if it is
1697 not, it will print an error and abort. If the usage type (specified
1698 with the -T option) is not defined in mke2fs.conf, mke2fs will print a
1699 warning but will continue. (Addresses Debian Bug #594609)
1701 Clarified error message from resize2fs clarifying that on-line
1702 shrinking is not supported at all. (Addresses Debian Bug #599786)
1704 Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
1705 displayed. (Addresses Debian Bug #555456)
1707 E2fsck will open the external journal in exclusive mode, to prevent
1708 the journal from getting truncated while it is in use due to a user
1709 accidentally trying to run e2fsck on a snapshotted file system volume.
1710 (Addresses Debian Bug #587531)
1712 Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
1715 The tune2fs program can now set the uninit_bg feature without
1718 The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
1719 default mount options settings which were added in 2.6.35.
1721 The e2fsck and dumpe2fs programs now support the new ext4 superblock
1722 fields which track where and when the first and most recent file
1723 system errors occurred. These fields are displayed by dumpe2fs and
1724 cleared by e2fsck. These new superblock fields were added in 2.6.36.
1726 Debugfs now uses a more concicse format for listing extents in its
1727 stat command. This format also includes the interior extent tree
1728 blocks, which previously was missing from stat's output for
1731 Debugfs has a new option, -D, which will request Direct I/O access of
1734 Mke2fs will skip initializing the inode table if a device supports
1735 discard and the discard operation will result in zero'ed blocks.
1737 Badblocks will now correctly backspace over UTF-8 characters when
1738 displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
1739 Debian Bugs #583782 and #587834)
1741 E2freefrag will now display the total number of free extents.
1743 Resize2fs -P no longer requires a freshly checked filesystem before
1744 printing the minimum resize size.
1746 Fixed a floating point precision error in a binary tree search routine
1747 that can lead to seg fault in e2fsck and resize2fs.
1749 Fixed a bug in e2fsck where if both the original and backup superblock
1750 are invalid in some way, e2fsck will fail going back to the original
1751 superblock because it didn't close the backup superblock first, and
1752 the exclusive open prevented the file system from being reopened.
1754 Fixed a big in e2freefrag which caused getopt parsing to fail on
1755 architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
1757 Clarified an mke2fs error message so a missed common in an -E option
1758 (i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
1759 results in a more understandable explanation to the user.
1761 Mke2fs now displays the correct valid inode ratio range when
1762 complaining about an invalid inode ratio specified by the user.
1764 Mke2fs now understands the extended option "discard" and "nodiscard",
1765 and the older option -K is deprecated. The default of whether
1766 discards are enabled by default can be controled by the mke2fs.conf
1769 Mke2fs's handling of logical and physical sector sizes has been
1770 improved to reflect the fact that there will be some SSD's with 8k and
1771 16k physical sectors arriving soon. Mke2fs will no longer force block
1772 size to be the physical sector size, since there will be devices where
1773 the physical sector size is larger than the system's page size, and
1774 hence larger than the maximal supported block size. In addition, if
1775 the minimal and optimal io size are not exported by the device, and
1776 the physical sector size is larger than the block size, the physical
1777 sector size will be used to set the Raid I/O optimization hints in the
1780 E2fsck will now display a better, more specific error message when the
1781 user enters a typo'ed device name, instead of blathering on about
1782 alternate superblocks.
1784 Fixed various Debian Packaging Issues
1786 Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
1787 #589345, #591083; Addresses Launchpad Bug: #505719)
1789 Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
1790 Polish, Swedish, and Vietnamese translations.
1796 Fix a dependency definition for the static and profiled blkid
1797 libraries which could cause compile failures in some configurations.
1798 (Addresses Debian Bug: #604629)
1800 Add support for Direct I/O in the Unix I/O access layer.
1802 Fixed a memory leak in the Unix I/O layer when changing block sizes.
1804 Fixed minor memory leaks in mke2fs.
1806 Added a new function to the ext2fs library, ext2fs_get_memalign().
1808 The tst_super_size test program will check to make sure the superblock
1809 fields are correctly aligned and will print them out so they can be
1810 manually checked for correctness.
1812 Fixed some makefile dependencies for test programs in lib/ext2fs.
1814 Reserved the feature flags and superblock fields needed for the Next3
1817 Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
1818 EXT4_INCOMPAT_EA_INODE.

1824 Mke2fs now gives a correct error message if the external journal
1825 device is not found. (Addresses Red Hat Bug #572935)
1827 Resize2fs -P will now refuse to print a minimum size if the file
1828 system is not clean. Previously it would go ahead and print a minimum
1829 size anyway, which might not be correct, leading to user confusion.
1831 E2fsck now tests for extents that begin at physical block 0 and
1832 rejects them as invalid. (Addresses Google Bug: #2573806)
1834 Fixed a bug in e2fsck which could cause it to crash when trying to
1835 remove an invalid extent and the block bitmaps hadn't yet been loaded.

1838 E2fsck now will completely skip time-based checks if the system clock
1839 looks insane or the option broken_system_clock is set in
1842 E2fsck would previously report an i_blocks corruption for a 4T file
1843 created using posix_fallocate; this bug has been fixed.
1845 E2fsck will now correctly mark a sparse journal as invalid and will
1846 delete and recreate the journal to address the problem.
1848 E2fsck would previously incorrectly ask the user whether she would
1849 like to abort the file system check after finding a problem --- and
1850 then abort regardless of the user's answer. This is annoying, and
1853 E2fsck can now continue even if it fails to recreate the resize
1854 inode; previously it would just abort the file system check
1857 E2fsck could potentially remove directory entries for inodes found in
1858 the unused region of the inode table; this would generally happen on
1859 ext4 file systems that do not use journaling. This bug has been fixed
1860 by not clearing these directory entries once it has been established
1861 that bg_unused_inodes may not be trustworthy; once pass #2 has been
1862 completed, e2fsck will restart the file system check from the
1863 beginning, and then it will be safe to delete any directory entries
1864 pointing to inodes that appear to be deleted. (Addresses Google Bug:
1867 E2fsck will not try to set the block group checksums if the user
1868 cancels the fsck with a control-C. It's a bad idea to set the
1869 checksums if e2fsck hasn't been completed, and it often results an the
1870 error message, "Inode bitmap not loaded while setting block group
1871 checksum info". (Addresses Launchpad Bug: #582035)
1873 The mke2fs program now queries the kernel for the physical as well as
1874 the logical sector size, and will not allow a blocksize below the
1875 logical, and will strongly encourage a blocksize at least as big as
1876 the physical blocksize. This is needed for 4k sector drives that
1877 emulate 512 byte sector sizes.
1879 Mke2fs will now allow a flex_bg size of 1. This is unusual, and
1880 rarely needed, but it is a legal value.
1882 E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
1883 not needed, and offer to clear it; this is a sign of a kernel bug, but
1884 more importantly, some released kernels may crash when this situation
1885 is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
1887 E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
1888 i_size is correct. (Kernels starting with 2.6.34 will set

1904 The regression test suite now uses its own mke2fs.conf file, so that
1905 downstream distributions want change the mke2fs.conf file which is
1906 distributed in the RPM or dpkg file, without worrying about screwing
1907 up the regression test results.
1909 Always build namei.o so that building with configure --disable-debugfs
1910 works correctly. Long-term, if we care about reduced e2fsprogs
1911 builds, we need a more general solution for deciding what .o files are
1912 needed for a particular build. Given that install floppies are going
1913 (gone?) the way the dodo bird, we probably don't care, though.
1914 (Addresses Sourceforge Bug: #2911433)
1916 Add configure options --enable-symlink-build and
1917 --enable-symlink-install, which allow e2fsprogs be built using
1918 symlinks instad of hard links, and to be installed using symlinks
1919 instead of hard links, respectively. It is useful when the file
1920 system where the build is taking place, or the file system where
1921 e2fsprogs is installed, can't handle hard links for some reason.

1941 thinking, "surely that message doesn't apply to *me*" :-(
1943 E2fsck -n will now always open the file system read-only. We now
1944 disallow certain combination of options which previously were manual
1945 exceptions; this is bad because it causes users to think they are
1946 smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
1947 -D" are no longer supported. (Addresses Launchpad Bug: #537483)
1949 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if

1952 message and proceeds. (Addresses Red Hat Bug: #569021. Addresses

2119 ==================================
2121 Fix a bug in e2fsck routines for reallocating an inode table which
2122 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
2123 filesystem feature with a relatively rare (and specific) filesystem
2124 corruption. This fix causes e2fsck to try to find space for a new
2125 portion of the inode table in the containing flex_bg, and if that
2126 fails, the new portion of the inode table will be allocated in any
2127 free space available in the filesystem.
2129 Make e2fsck less annoying by only asking for permission to relocate a
2130 block group's inode table once, instead of for every overlapping
2131 block. Similarly, only ask once to recompute the block group
2132 checksums, instead of once for each corrupted block group's checksum.
2134 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
2135 not present, and it needs to fall back to using the FIBMAP ioctl.
2137 Fix filefrag to correctly print the number of extents for zero-length
2138 files. (Addresses Debian Bug: #540376)
2140 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
2141 to more easily debug the FIBMAP code.

2156 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
2157 last mount times are in the future, they are corrected even if
2158 buggy_init_scripts is set. This is needed because otherwise resize2fs
2159 will refuse to resize the filesystem, even after running "e2fsck -f".

2212 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
2213 will be careful not to close the file descriptor for its unix domain
2214 socket when it detaches itself from the controlling tty. Also add
2215 safety checks so that if the unix domain socket between the uuid
2216 library and uuidd program is closed for any reason, both the library
2217 and the uuidd will return an appropriate error code instead of looping
2218 in an infinite loop.

2259 uninitalized data into the portion of the inode beyond the first 128
2260 bytes when operating on inodes mapped via extents; potentially
2261 corrupting filesystems.

2315 ===============================
2317 Fix a critical regression in e2fsck introduced version 1.41.5 which
2318 can undo updates to the block group descriptors after a journal replay.
2320 If e2fsck receives an I/O error while replaying the journal, prompt
2321 the user whether they want to ignore the error or not; if e2fsck is
2322 run in preen mode, force fsck to abort the preen pass.
2324 Fix a bug which would cause e2fsck to core dump if the filesystem
2325 contains a corrupt extent header, and the user declines to clear the
2326 inode. (Addresses Sourceforge Bug: #2791794)
2328 Fix e2fsck to restart only once in the case of multiple block groups
2329 which inodes in use that are in the uninitialized part of the block
2330 group's inode table.
2332 To reduce user confusion, if the /etc/mtab file is missing
2333 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
2334 new, explicit error code to indicate this case. This will cause
2335 e2fsck to give a clearer error message when the user is using buggy
2336 rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
2339 Fix e2fsck so that if the primary group descriptors are corrupted, but
2340 the backup superblock is entirely invalid, to go back to using (and
2341 fixing) the priary group descriptors instead of completely giving up
2342 on the filesystem. (Addresses Debian Bug: #516820)
2344 Change e2fsck to not abort a preen pass if an inode is found to have
2345 i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
2346 kernels (post 2.6.29) will ignore this field. So let's fix it
2347 automatically during the preen pass instead of forcing the user to fix
2348 this up manually. (Addresses Debian Bug: #526524)
2350 Add resource tracking for e2fsck passes 1b through 1d.
2352 Speed up e2fsck by eliminating unnecessary journal checks if the
2353 filesystem is already mounted and doesn't need recovery (since the
2354 kernel would have run the journal when the filesystem was mounted.)
2355 Also speed up e2fsck by avoiding unnecessary block group descriptor
2356 updates in ext2fs_close().
2358 Add support to chattr to migrate inodes from using direct/indirect
2361 Avoid corrupting the filesystem if there is an attempt to shrink a
2362 filesystem using resize2fs smaller than posible by making
2363 ext2fs_set_bmap() more careful not to delete the old block until the
2364 new block can be inserted. In addition, fix a bug in how the minimum
2365 size of the filesystem (plus a safety margin) is calculated, and
2366 modify resize2fs to refuse to shrink the filesystem below that minimum
2367 size without the force flag.
2369 Teach blkid to try to figure out DM device names using take advantage
2370 of information in sysfs when running on kernels (2.6.29 and later)
2371 which provide this information in /sys/block/dm-<N>/dm/name; this is
2372 much faster than scanning for the devncie number in /dev/mapper.
2374 Fix blkid to prefer /dev/mapper/<name> device names instad of the
2375 private /dev/dm-X names.
2377 Add an -a option to debugfs's close_filesys command which writes any
2378 changes to the superblock or block group descriptors to all of the
2379 backup superblock locations.
2381 Add support to the filefrag program to use the FIEMAP ioctl.
2383 Update Chinese translation from the Translation Project.

2406 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
2407 avoid compile problems caused by not having a prototype for
2408 ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
2410 Update the config.guess and config.sub file to the latest from the
2411 FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
2412 Debian Bug: #528330)
2414 Add a new function, ext2fs_extent_open2(), which behaves like
2415 pext2fs_extent_open(), but uses the user-supplied inode structure
2416 when opening an extent instead of reading the inode from disk.
2419 E2fsprogs 1.41.5 (April 23, 2009)
2420 =================================
2422 Fix a number of filesystem corruption bugs in resize2fs when growing
2423 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
2426 Debugfs can now set i_file_acl_high via the set_inodes_field command,
2427 and print a 64-bit file acl. This is useful for debugging filesystem
2428 corruptions where the high bits of i_file_acl_high are set. E2fsck
2429 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
2430 since some Linux kernel versions pay attention to this field even when
2433 Speed up e2fsck when checking clean filesystems by avoiding
2434 unnecessary block reads, and coalescing the block group descriptor
2435 blocks so they are read using a single read operation.
2437 The libuuid library will now close all file descriptors before running
2438 uuidd. This avoids problems when the calling program has open sockets
2439 which then never get closed because uuidd is a long-running helper
2440 daeomn. (Addresses Launchpad bug: #305057)
2442 In order to avoid unnecessary full filesystem checks by e2fsck after
2443 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
2444 the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
2446 Mke2fs will avoid trying to create the journal when run in
2447 superblock-only mode (mke2fs -S), since the left-over journal in the
2448 inode table will cause mke2fs to fail.
2450 Fix a bug in libext2fs functions that check to see if a particular
2451 device or filesystem image is mounted, which would cause these
2452 functions to report that a file identical to the (relative) pathname
2453 used by a pseudo-filesystem was mounted when in fact it was not.
2455 Update Czech translation from the Translation Project.
2457 Add Chinese (simplified) translation from the Translation Project.
2459 Fix support for external journals (which was broken in e2fsprogs
2462 Fix a regression in debugfs where the "stat" command when no
2463 filesystem was open would cause debugfs to crash with a segmentation
2466 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
2467 used to support filesystems without a journal. Update the blkid
2468 library so it understands this.
2470 The blkid library will remove an entry from the blkid cache
2471 representing the entire disk if partitions are found, since presuambly
2472 the device previously had no partition table, but has now transitioned
2473 to using a partition table.
2475 Add a check to mke2fs and tune2fs that the argument to the -m option
2476 (which specifies the reserved ratio) must be greater than zero.
2477 (Addresses Debian Bug: #517015)
2479 Add support for tracking the number kilobytes written to the
2480 filesystem via the superblock field s_kbytes_written. It will be
2481 updated by the kernel as well as by e2fsprogs programs which write to
2482 the filesystem. This is useful for tracking the wear to filesystems
2483 on Solid Sstate Drives.
2485 Fix compatibility issue in the libext2fs info file and makeinfo
2486 version 4.12. (Addresses Red Hat Bugzilla: #481620)
2488 Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
2490 Fixed various Debian packaging issues --- see debian/changelog for
2491 details. (Addresses Debian Bug: #506279)
2496 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
2499 Fix various gcc compilation warnings and other programming cleanups.
2500 (Addresses Red Hat Bugzilla: #486997)
2502 Add support for building the blkid command statically.
2504 Add support for disabling the built-in blkid library in favor of a
2505 system-installed blkid implementation via the configure option
2509 E2fsprogs 1.41.4 (January 27, 2009)
2510 ===================================
2512 Fixed a bug which could sometimes cause blkid to return an exit value
2513 of zero for a non-existent device (Addresses Debian Bug: #502541)
2515 Blkid will now recognize ext3 filesystems that have the test_fs flag
2516 set as ext3 filesystems.
2518 The blkid library will now recognize btrfs filesystems and swap
2519 devices currently used by user-level software suspend.
2521 Tune2fs now updates the block group checksums when changing the UUID
2522 to avoid causing e2fsck to complain vociferously at the next reboot.
2524 Tune2fs's inode size resizing algorithms have been fixed so it is not
2525 vastly inefficient for moderate-to-large filesystems, due to some
2526 O(n**2) and O(n*m) algorithms that didn't scale well at all.
2528 Fix tune2fs's inode resizing algorithm so it will not corrupt
2529 filesystems laid out for RAID filesystems; in addition, tune2fs will
2530 refuse to change the inode size for filesystems that have the flex_bg
2531 feature enabled. (This is a limitation in the current implementation
2534 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
2535 filesystems with 32-bit block numbers, when the headers for 64-bit
2536 block numbers was added. This regression has been fixed.
2538 Debugfs's ncheck command has been fixed to avoid printing garbage
2539 characters at the end of file names.
2541 Fix resize2fs for ext4 filesystems. Some blocks that that need moving
2542 when shrinking filesystems with uninit_bg feature would not be moved.
2543 In addition, blocks and inode table blocks were not being correctly
2544 freed when shrinking filesystems with the flex_bg feable, which caused
2545 resize2fs -M to fail. Finally, when blocks are moved, make sure the
2546 uninitialized flag in extents is preserved.
2548 Fix bug which caused dumpe2fs to abort with an error if run on a
2549 filesystem that contained an external journal.
2551 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
2552 for this in argv[0] to provide better legacy support for these
2553 distributions. This is a practice that should NOT be continued,
2556 Mke2fs now has a new option -U, which allows the user to specify the
2557 UUID that should be used for the new filesystem.
2559 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
2560 minus one block. This allows users who have read that ext3 supports
2561 up to 16TB filesystems and who create a 16TB LVM to not get confused,
2562 since the true limit is really 16TB minus one block.
2564 E2fsck will no longer abort an fsck run if block group has an errant
2567 E2fsck now distinguishes between fragmented directories and fragmented
2568 files in verbose mode statistics and in the fragcheck report.
2570 Fix a bug in e2fsck which casued it double count non-contiguous
2571 extent-based inodes.
2573 E2fsck will leave some slack space when repacking directories to allow
2574 room for a few directory entries to be added without causing leaf
2575 nodes to be split right away.
2577 Fix a bug which caused e2fsck to crash when it comes across a
2578 corrupted interior node in an extent tree with the error message:
2579 "Error1: Corrupt extent header on inode XXXXXX"
2581 E2fsck problem descriptions involving the journal are no longer
2582 referred to as "ext3" problems, since ext4 filesystems also have
2585 Fix a long-standing bug in e2fsck which would cause it to crash when
2586 replying journals for filesystems with block sizes greater than 8k.
2588 Update Catalan translation from the Translation Project.
2590 Fixed various Debian packaging issues --- see debian/changelog for
2591 details. (Addresses Debian Bugs: #503057, #502323, #511207)
2596 Fix build of e2fsck.profiled, and add support for building profiled
2597 binaries in the misc directory if configured with --enable-profile.
2599 The ext2fs_open() function now performs more sanity checks on the
2600 superblock to avoid potential divide by zero errors by other parts of
2603 The ext2fs_read_inode_full() function now has a safety check to avoid
2604 a segmentation fault on corrupted filesystems.
2606 The ext2fs_new_inode() function now has a sanity check so that if the
2607 s_first_inode field in the superblock is insane, it will return
2608 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
2610 To avoid segmentation faults, ext2fs_block_alloc_stats() and
2611 ext2fs_inode_alloc_stats() now validates the passed inode or block
2612 number to avoid overrunning an array boundary.
2614 Various signed/unsigned errors for variables containing block numbers
2617 Accomodations for gcc's stupidity in not realizing that constant
2618 strings that do not contain a '%' character are safe to use in format
2619 strings have been made so that distributions that want to compile
2620 e2fsprogs with -Werror=format-security have an easier time doing so.
2622 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
2624 Added the utility make-sparse.c to the contrib directory.
2626 The ext2fs_block_iterate2() function now reflects errors from
2627 ext2fs_extent_set_bmap() to the caller, if the callback tries to
2628 change a block on an extent-based file, and ext2fs_extent_set_bmap()
2629 fails for some reason (for example, there isn't enough disk space to
2630 split a node and expand the extent tree.
2632 The ext2fs_block_iterate2() function will preserve the uninit flag in
2633 extents when the callback function modifies a block in an extent-based
2636 E2fsck will now flag filesystems that have an insane s_first_ino field
2637 in their superblock, and attempt to use a backup superblock to repair
2641 E2fsprogs 1.41.3 (October 12, 2008)
2642 ===================================
2644 E2fsck has been fixed so it prints the correct inode number for
2645 uinit_bg related problems.
2647 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
2648 is available on linux. This can be disabled via a configuration
2649 option in /etc/e2fsck.conf.
2651 Fix a file descriptor leak in libblkid when checking to see if an ext4
2652 or ext4dev module exists.
2654 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
2655 while trying to close a filesystem can lead to infinite loops.
2656 (Addresses Red Hat Bugzilla #465679)
2658 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
2659 will cause resize2fs to drop into an infinite loop. (Addresses Red
2660 Hat Bugzilla: #465984)
2662 Add a check in the Unix I/O functions in libext2fs so that when a
2663 device is opened read/write, return an error if the device is
2664 read-only using the BLKROGET ioctl.
2666 Fix debugfs's ncheck command so that it prints all of the names of
2667 hardlinks in the same directory.
2669 Fix a bug in libblkid so it correctly detects whether the ext4 and
2670 ext4dev filesystems are available, so that the ext4dev->ext4
2671 fallback code works correctly.
2676 Fix a parallel build problem by making sure util/subst is built before
2677 trying to build the lib/et directory. (Addresses Sourceforge Bug:
2680 Updated "make depend" information for crc16.o
2683 E2fsprogs 1.41.2 (October 2, 2008)
2684 ==================================
2686 Fix e2fsck's automatic blocksize detection. This fixes a regression
2687 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
2688 specifies a block number using the -b option if the blocksize option
2689 isn't also specified using -B. Unfortunately, users very commonly
2690 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
2691 superblock; in fack e2fsck will often suggest this kind of command
2694 Enhance the debugfs's "ncheck" command so it will print all of the
2695 pathnames for the specified inodes. (Previously, in some cases ncheck
2696 might not print a pathname for an inode at all if some of the other
2697 inodes had multiple hard links.)
2699 Enhance debugfs's "hash" command so the hash seed can be specified via
2700 a command-line option. In addition, allow the hash algorithm to be
2701 specified by name instead of just by number.
2703 Fix e2fsck so that we don't accidentally print the translation file's
2704 header when asking the user a custom question so there is no prompt
2705 defined for a particular problem record. For example, the question
2706 "Run journal anyway" will get the PO header tacked on because e2fsck
2707 erroneously passed the null string to _(). (Addresses Launchpad Bug:
2710 Enhance badblocks so that it can test a normal file which is greater
2713 Enhance the badblocks command so that it displays the time and
2714 percentage complete when in verbose mode. (Addresses Debian Bug:
2717 Fix a potential memory leak in a error handling path in debugfs's
2720 Fix a potential memory corruption problem if a memory allocation fails
2723 Fix the usage message for debugfs's logdump command to be consistent
2724 with its man manpage.
2726 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
2727 and Sweedish translation from the Translation Project.
2729 Add documentation for the file I/O functions to the libext2fs.texinfo
2730 file. (Addresses Debian Bug: #484877)
2732 Update and clarified various man pages. (Addresses Launchpad Bug
2733 #275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
2735 Fixed various Debian packaging issues --- see debian/changelog for
2736 details. (Addresses Debian Bug: #497619)
2741 Fix a potential file descriptor leack in libcom_err by setting the
2742 close-on-exec flag for a fd used for debugging. (Addresses Red Hat
2745 Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
2746 has been carrying a patch for a long time to prevent a largely
2747 theoretical race condition if a multi-threaded application adds and
2748 removes error tables in multiple threads. Unfortunately SuSE's
2749 approach breaks compatibility by forcing applications to link and
2750 compile with the -pthread option; using pthread mutexes has
2751 historically been problematic. We fix this by using sem_post/sem_init
2754 Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
2755 Sourceforge Bug: #2087502)
2757 Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
2758 libraries when using ELF shared libraries.
2760 Fix ELF shared library when building on systems that don't already
2761 have the e2fsprogs shared libraries already installed. (Addresses
2762 Sourceforge Bug: #2088537)
2764 Fix the pkg-config files so they work correctly when linking with
2765 static libraries and fix the include directory so programs don't have
2766 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
2767 instead. (Addresses Sourceforge Bug: #2089537)
2769 Make sure ext2fs_swab64() is compiled for all platforms, and not just
2770 for x86. (Addresses Debian Bug: #497515)
2772 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
2773 non-x86 platforms. (They had been removed for x86 earlier.)
2775 Fix diet libc compilation support, which had bitrotted due to lack of
2776 TLC. Fixing this improves general portability.
2778 When installing the link library when using ELF shared libraries,
2779 avoid using absolute pathnames if the link library and the shared
2780 library are installed in the same directory. (Addresses Sourceforge
2783 Fix gen-tarball so it will work even if the top-level directory has
2784 been renamed to something other than "e2fsprogs". Also make
2785 gen-tarball print the size of the resulting tar.gz file.
2788 E2fsprogs 1.41.1 (September 1, 2008)
2789 ====================================
2791 Many people are forgetting to update their mke2fs.conf file, and this
2792 causes ext3, ext4, and ext4dev filesystems won't get created with the
2793 proper features enabled. We address this in two ways. First, mke2fs
2794 will issue a warning if there is not definition for an ext3, ext4, or
2795 ext4dev filesystem and the user is trying to create such a filesystem
2796 type. Secondly, when installing from a source build, "make install"
2797 will provide basic configuration file handling for /etc/mke2fs.conf.
2798 If it exists, and does not mention ext4dev, it will be moved aside to
2799 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
2800 be installed. If the existing /etc/mke2fs.conf file does mention
2801 ext4dev, then "make install" will install official mke2fs.conf file as
2802 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
2803 they should look to see if any changes need to be merged.
2805 The mke2fs program will now create the journal in the middle of the
2806 filesystem, since this minimizes seek times on average for fsync-heavy
2807 workloads. In addition, mke2fs will now create journals using extents
2808 for filesystems that support them. This results in a more efficient
2809 encoding for the journal since it eliminates the need for using
2812 The mke2fs program will avoid allocating an extra block to the
2813 journal. (Addresses Sourceforge Bug: #1483791)
2815 Mke2fs will correctly enforce the prohibition against features
2816 (specifically read-only features) in revision 0 filesystems. (Thanks
2817 to Benno Schulenberg for noticing this problem.)
2819 Mke2fs previously would occasionaly create some slightly non-optimally
2820 placed inode tables; this bug has been fixed.
2822 The mke2fs and tune2fs programs now print the correct usage message
2823 describing the maximum journal size. (Addresses Debian Bug: #491620)
2825 Add support for setting the default hash algorithm used in b-tree
2826 directories in tune2fs (from a command-line option) or mke2fs (via
2827 mke2fs.conf). In addition, change the default hash algorithm to
2828 half_md4, since it is faster and better.
2830 The blkid library will now recognize MacOS hfsx filesystems, and
2831 correctly extract the label and uuid for hfs, hfsx, and hfsplus
2832 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
2834 The blkid library has improved detection of JFS and HPFS filesystems.
2835 (Addresses Launchpad Bug: #255255)
2837 The blkid library is now much more efficiently handling devicemapper
2838 devices, mainly by no longer using the devicemapper library. This can
2839 speed up access for systems with a large number of device mapper
2842 Blkid had a number of cache validation bugs in libblkid that have been
2843 fixed. (Addresses Debian Bug: #493216)
2845 Resize2fs will now properly close out the "updating inode references"
2846 progress bar so there is a newline printed before printing the final
2847 "resize is successful" message.
2849 Resize2fs will now correctly handle filesystems with extents and/o
2850 uninitialized block groups correctly when file/directory blocks need
2851 to relocated (i.e., when shrinking a filesystem or if the resize_inode
2852 is not present). To support this, the ext2fs library now supports
2853 initializing inode and block bitmaps that are not yet initialized when
2854 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
2855 addition, e2fs_block_iterate2() can now support changing the location
2856 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
2857 been optimized to avoid creating unnecessary new extents when updating
2858 the location of blocks in the extent tree. This will also help out
2859 e2fsck's recovery of obscurely corrupted filesystems with extents,
2860 when blocks are claimed by multiple inodes.
2862 Add support for on-line resizing ext4 filesystem with the flex_bg
2863 filesystem feature. The method for doing so is not optimal, but to do
2864 a better job will require kernel support.
2866 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
2867 debugfs programs to not be able to read e2image files; the signed
2868 vs. unsigned bug in the code which read bitmaps from the e2image has
2869 been fixed. (Addresses Debian Bug: #495830)
2871 Resize2fs is now correctly managing the directory in-use counts when
2872 shrinking filesystems and directory inodes needed to be moved from one
2873 block group to another. This bug has been around since e2fsprogs
2874 1.26, and is largely harmless, but does cause a filesystem corruption
2875 which will be flagged by e2fsck after the filesystem has been shrunk.
2877 E2fsck will no longer issue spurious complaints about the inode size
2878 caused by very large extent-based files, and by blocks reallocated
2879 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
2880 Kernel Bugzilla: #11341)
2882 Mke2fs will now set the creation timestamp on the lost+found directory
2883 and the root directory. (More generally, all new inodes created using
2884 the ext2fs library will correctly set the creation timestamp.)
2886 E2fsck now correctly calculates ind/dind/tind statistics in the
2887 presence of extent-based files. In addition, "e2fsck -v" will report
2888 statistics of the depth of extent trees in the filesystem. E2fsck can
2889 also give an inode fragmentation report using "e2fsck -E fragcheck"
2890 which can be useful when debugging the kernel block allocation
2893 Fix support for empty directory blocks in ext4 filesystems with 64k
2894 blocksize filesystems.
2896 E2fsck will now print the depth of corrupt htree directories.
2898 Debugfs's htree command now correctly understands extent-based
2899 directories. It will also print out the minor hash as well as the
2902 Debugfs has a new command which will print the supported features of
2903 e2fsprogs, to enable scripts to know whether the installed version of
2904 e2fsprogs can support a specific feature.
2906 Debugfs will now write files using extents for filesystems that
2909 The error message printed by "tune2fs -I" if the inode size was too
2910 small was rather confusing, so it has been improved. Also, we won't
2911 try to create an undo log until we know that command-line-specified
2912 parameters such as "tune2fs -I <inode size>" are valid.
2914 Given some filesystems found "in the wild" that had non-zero block
2915 group checksums even though the uninit_bg/gdt_sum feature was not
2916 enabled, e2fsck would issue spurious error messages. Teach
2917 ext2fs_group_desc_csum_verify() to ignore the block group checksum
2918 entirely if the feature flag is not set. (Addresses Debian Bug:
2921 The blkid program will now print out a user-friendly listing of all of
2922 the block devices in the system and what they contain when given the
2923 -L option. (Addresses Debian Bug: #490527)
2925 The filefrag program now has a more accurate calculation for the
2926 number of ideal extents. (Addresses Debian Bug: #458306)
2928 The test I/O manager is now enabled by default, but its overhead is
2929 only incurred when it would be enabled via the TEST_IO_FLAGS or
2930 TEST_IO_BLOCK environment variables.
2932 Typographical errors in various program strings and usage messages
2933 have been fixed; most of these were pointed out by the e2fsprogs
2934 message catalog translators. (Thanks, translators!)

2959 Sourceforge Bug: #2019287)
2961 The ext2fs_extent_set_bmap() had some bugs when setting the first

2970 Various ext2fs library functions --- ext2fs_block_iterate2(),

2975 Ext2ed was failing to build because masix support had been removed in
2976 the rest of e2fsprogs, so ext2ed no longer has masix support, either.

2979 it is set when configure is called. (Addresses Sourceforge Feature
2982 Libuuid is now more portable to the Windows platform. (Addresses
2983 Sourceforge Feature Request: #1937287)
2985 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
2986 bare echo commands so that configure flags such as --quiet work
2987 correctly. (Addresses Sourceforge Patches: #2058794)
2989 A few uses of sprintf have been removed from the ext2fs library to
2990 make life easier for bootloaders with a limited libc environment.

3001 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
3002 top-level Makefile. That automatic rule is used to better support
3003 SCCS, but it caused problems for a particular niche distribution which
3004 likes to use configure.sh files to store the configure options used to
3005 build a package. Unfortuntaely GNU make will use the configure.sh to
3006 replace the configure script, resulting in a self-inflicted fork bomb
3007 leading to an out-of-memory crash.
3009 To support old GNU C compilers don't use C99/C++ comments, but only
3010 K&R style comments, and don't try to use __builtin_expect if __GNUC__
3011 is less than 3. (__builtin_expect is only supported for gcc versions
3012 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
3013 this is an optimization, we only try to use __builtin_expect for gcc 3
3016 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
3017 __LITTLE_ENDIAN, which are only defined by glibc's header files and
3018 hence isn't portable.
3020 For the convenience for some distributions that need a static tune2fs,
3021 the Makefile for misc/ now has a tune2fs.static target.
3023 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
3024 for extent-based files
3026 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
3029 All source files no longer have any trailing white space.
3031 The io_channel_read_blk64() and io_channel_write_blk64() functions are
3032 now functions instead of C preprocessor macros to provide better
3033 forward compatibility.

3040 Fix a parallel build problem in e2fsprogs.
3042 E2fsprogs is now more portable to Solaris.
3043 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
3045 * Scripts do not assume that /bin/true is always in /bin
3046 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
3047 * Flush stdio handles before calling setbuf(), since Solaris will
3048 discard any pending output to the stream.
3049 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
3050 picky about which C compiler can beused for SUSv3 conformance.
3051 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
3052 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
3053 Since we need some SUSv3 functions, consistently use SUSv3 so
3054 that e2fsprogs will build on Solaris using c99.
3055 * Solaris C99 does not support varargs C preprocessor macros
3056 * Solaris header files pollute the C namespace if in/netinet.h
3057 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
3059 * Solaris ships with a pathetically ancient shell in /bin/sh so we
3060 avoid the use of various more avanced shell constructs such as $().
3062 The "make rpm" command will now take some extra configure optiosn from
3063 the build environment without needing to patch the source tree.
3065 The ext2fs_add_dir_block() function will now grow the dblist more
3066 aggressively as an optimization to avoid copying the array too often.
3068 The e2fsck_write_bitmaps() will write the block and inode bitmaps
3069 together instead of in two passes.
3072 E2fsprogs 1.41 (July 10, 2008)
3073 ==============================
3075 Add support for ext4 filesystem features, in particular extents,
3076 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
3077 support for checking journal checksums. Debugfs will print new
3078 superblock and inode fields that were defined for ext4. For example,
3079 the nanosecond and i_version fields of an inode, and the
3080 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
3081 Note: Resize2fs doesn't currently support the combination of flex_bg
3082 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
3084 Tune2fs can support migrating a filesystem from using 128 byte inodes
3085 to 256 byte inodes, so it can take advantage of the full features of
3088 Add support for "undo" support. E2fsck and mke2fs can optionally
3089 record an undo log which can replayed by the program e2undo.
3091 E2fsck could damage a filesystem by trying to relocate inode tables
3092 due to corrupted block group descriptors, where the attempted inode
3093 table relocation would do far more harm than good. E2fsck has been
3094 fixed to detect this these sorts of corrupted block group descriptors
3095 much earlier in e2fsck processing, so it can try to use the backup
3096 superblock and block group descriptors first. This should be a much
3097 better strategy for recovering these types of corrupted filesystems.
3098 (Addresses Sourceforge Bug: #1840291)
3100 E2fsck will display a more understandable message when the last check
3101 field in the superblock is in the future. (Addresses Debian Bug:
3104 E2fsck now performs more extensive and careful checks of extended
3105 attributes stored in the inode.
3107 Enhance mke2fs to print a more explanatory error message when
3108 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
3111 Fix mke2fs to use a default block size of 4k when formatting an
3112 external journal device. This is done by using a fixed filesystem
3113 type list that consists only of the single filesystem type "journal"
3114 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
3115 Debian Bug: #488663)
3117 Speed up how mke2fs writes the journal data blocks by writing the disk
3118 blocks in larger chunks.
3120 Fix blkid handling of stale devices. Fix a bug which could cause a
3121 core dump while garbage collecting the blkid cache, and assure that
3122 blkid_find_dev_with_tag() never returns a non-existent device. Also,
3123 if a filesystem is found at a new /dev location, eliminate any
3124 duplicate stale entries which can not be verified.
3125 (Addresses Debian Bugs: #487758, #487783)
3127 Add more paranoid checks for LVM volumes and swap partitions in
3128 blkid's probe function, to reduce the chances of false positives.
3130 The mke2fs program now has a much more sophisticated system for
3131 controlling configuration parameters of a newly created filesystem
3132 based on a split filesystem and usage type system. The -t option to
3133 mke2fs was a deprecated alias to -c; it now specifies a filesystem
3134 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
3135 separated usage list. The filesystem type information and type
3136 information is used to extract configuration parameters from the
3137 /etc/mke2fs.conf file.
3139 The mke2fs program will no longer complain and request the -f option
3140 when the user tries to create a filesystem with greater than 2**31
3143 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
3144 adjust the mke2fs.conf file so filesystems for the Hurd are created
3145 with a blocksize of 4096 and inode size of 128, which is all it knows
3146 how to handle. (Addresses Debian Bug: #471977)
3148 Mke2fs will always make sure that lost+found always has at least 2
3149 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
3151 Resize2fs will now print the minimum needed filesystem size if given
3152 the -P option, and will resize the filesystem to the smallest possible
3153 size if given the -M option.
3155 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
3156 blocks are consumed during an off-line resize.
3158 The "ls" command in debugfs now supports the -p option, which causes
3159 it to quote the filenames so that spaces or tabs in directory entries
3160 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
3161 Sourceforge Feature Request: #1201667)
3163 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
3166 The chattr program will return a non-zero exit code in case of
3167 failures, and error messages can be suppressed with the -f option.
3168 (Addresses Red Hat Bugzilla: #180596)
3170 Fix a bug in badblocks which caused it to overrun an array and likely
3171 crash if more than 8 test patterns are specified using the -t option.
3172 (Addresses Debian Bug: #487298)
3174 Add support to badblocks to limit how quickly it reads from the disk
3175 drive (so it can be used for background scrubbing), and so it will
3176 abort after finding a given number of errors.
3178 Remove support for the legacy big-endian filesystem format which only
3179 existed on extremely long-dead PowerPC kernels almost a decade ago.
3181 Remove MASIX support from e2fsprogs.
3183 Add I/O statistics reporting to e2fsck.
3185 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,

3210 Clean up the badblocks group so to make it more portable and robust.
3212 Avoid using predictable filenames in /tmp in blkid's regression test
3213 suite. Also remove bashism's in the regression test script.
3215 If the configure script is given --with-diet-libc, don't use thread
3216 local storage, since diet libc doesn't support TLS. (Addresses
3217 Sourceforge Bug: #2000654)
3219 Fix the blkid regression test suite to tolerate older versions of
3220 mkswap that don't support the -U option.
3222 A few library routines have been converted to support 64-bit block
3223 numbers; in particular, the I/O manager functions, the test_io,
3224 inode_io, and unix_io managers have all be converted to support 64-bit
3227 Debugfs can now be extended for use by test programs. See
3228 lib/ext2fs/extents.c for an example for how it can be used. The test
3229 program links against the debugfs object files, and provides
3230 additional commands by defining an auxiliary libss command table.
3232 The lazy_bg filesystem feature, which was only used by developer's
3233 testing, has been removed since it has been largely supplanted by
3234 uninit_bg. This also simplifies the code.
3237 E2fsprogs 1.40.11 (June 17, 2008)
3238 =================================
3240 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
3241 percentage of reserved blocks. (Addresses Debian Bug: #452639)
3243 Updated Spanish and Catalan translations.
3245 Fixed various Debian packaging issues --- see debian/changelog for
3246 details. (Addresses Debian Bugs: #483962, #483023)
3248 Add detection for ZFS volumes to the libblkid library.
3250 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3251 (Addresses Debian Bug: #486463)
3256 Fix marginal C code in probe_lvm2() function to the blkid library more
3257 portable for older compilers.
3259 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
3261 Fix ext2fs_swap{16,32,64} functions so they can be used by external
3262 applications on big-endian machines. (Addresses Debian Bug: #484879)
3265 E2fsprogs 1.40.10 (May 21, 2008)
3266 ================================
3268 When deciding whether or not to revalidate a blkid cache entry, if the
3269 device's mtime is newer than the last time the cached entry was
3270 validated, force a revalidation.
3272 Fix a potential data corruption bug in e2fsck in the journal replay.
3273 The chances of this is happening is extremely remote, especially the
3274 default data=ordered or data=writeback modes. However, if a block
3275 which has been journalled starts with the first four bytes 0xc03b3998,
3276 when e2fsck replays the journal, those four bytes will be replaced
3277 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
3278 metadata to begin with those fatal 4 byte sequence, and unless
3279 data=ordered mode is in use, data blocks are never journaled.
3281 Updated German, Dutch, Sweedish, and Vietnamese translations.
3286 Fixed various Debian packaging issues --- see debian/changelog for
3289 Remove default sizes of types when cross compiling, since autoconf
3290 2.50 can figure this out automatically now.
3293 E2fsprogs 1.40.9 (April 27, 2008)
3294 =================================
3296 SuSE's security team audited uuidd and came up with a few minor
3297 issues. None of them are serious given that uuidd runs setuid as a
3298 unprivileged user which has no special access other than libuuid
3299 directory, but it's good to get them fixed.
3301 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
3302 work correctly with in-inode extended attributes.
3304 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
3307 Debugfs will avoid using a pager if the standard output is not a tty.
3309 Fix debugfs and tune2fs to correctly handle daylight savings time when
3310 parsing a time string.
3312 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3314 Fix fsck completion bars when multiple filesystems were being checked
3315 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
3316 #203323, Addresses Sourceforge Bug: #1926023)
3318 Fix fsck so that progress information is sent back correctly when
3319 multiple filesystems are being check and the output of fsck is being
3320 redirected to a file descriptor. Also, include the device name (w/o
3321 spaces) in the progress information sent back via a file descriptor.
3322 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
3325 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
3327 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
3328 signal to its child process.
3330 Fix mke2fs's creation of are resize inode when there is a non-standard
3331 s_first_data_block setting.

3334 not reported correctly. 9Addresses Launchpad Bug: #220275)
3336 Mke2fs will not allow the logically incorect combination of
3337 resize_inode and meta_bg, which had previously caused mke2fs to create
3338 a corrupt fileystem.
3340 Fix fsck in German locales so that a 'j' means yes.

3347 Fixed various Debian packaging issues --- see debian/changelog for
3350 Update valgrind options in test_script to work with valgrind 3.2.3

3357 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
3359 Fix build system so that if texinfo is not installed, it won't print a
3360 (harmless) error message.
3363 E2fsprogs 1.40.8 (March 13, 2008)
3364 =================================
3366 Fixed e2image -I so it works on image files which are larger than 2GB.
3368 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
3369 the size is larger than the number of blocks found in the inode, don't
3370 try to allocate extra empty blocks at the end of the directory to make
3371 up the difference; there's no point to doing that. In addition, if
3372 the size is not a multiple of a blocksize, always fix it.
3374 E2fsck handled a pass 2 "should never happen error" by not giving
3375 enough information and then core dumping. Unfortunately, it was all
3376 too easy to trigger the "should never happen" situation if a
3377 directory's inode size was not correct. This has been fixed, but
3378 e2fsck has also been taught how to handle this situation more
3379 gracefully, by simply removing the inode hash tree information, so
3380 that it can be rebuilt again after e2fsck's pass 3. (Addresses
3381 Launchpad Bug: #129395)
3383 Resize2fs had a bug resizing large inodes with extended attributes
3384 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
3385 completely on big-endian systems such as PowerPC. The bug should be
3386 completely fixed now. Yay for regression test suites. (Addresses Red
3387 Hat Bugzilla: #434893)
3389 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
3390 translations. Many thanks to Philipp Thomas from Novell for stepping

3395 make it clear that it is just clearing the HTREE information, not the
3398 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3403 Add new functions, ext2fs_dblist_get_last() and
3404 ext2fs_dblist_drop_last(), which allows the caller to examine the last
3405 directory block entry added to the list, and to drop if it necessary.
3407 Fixed a portability problem in libblkid with DJGPP.
3409 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
3410 to Philipp Thomas for pointing this out.
3412 If the info files are not built, change "make install" so it doesn't
3413 fail with an error code.
3416 E2fsprogs 1.40.7 (February 28, 2008)
3417 ====================================
3419 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
3420 depreciate the -s option, since it can result in filesystems which
3421 e2fsck can't fix easily. There are very good reasons for wanting to
3422 disable sparse_super; users who wants to turn off sparse_super can use
3423 debugfs. (Addresses Sourceforge Bug: #1840286)
3425 Add missing options to mke2fs's usage message. (Addresses Sourceforge
3428 Fix bug in resize2fs when large (greater than 128 byte) inodes are
3429 moved when a filesystem is shrunk; it was only moving the first 128
3430 bytes, so extended attributes were not getting moved. (Addresses Red
3431 Hat Bugzilla: #434893)
3433 E2fsck now prints an explicit message when the bad block inode is
3434 updated, to avoid confusion about why the filesystem was modified.
3435 (Addresses Sourceforge Bug: #756460)
3437 Allow mke2fs and tune2fs manipulate the large_file feature.
3438 Previously we just let the kernel and e2fsck do this automatically,
3439 but e2fsck will no longer automatically clear the large_file feature.
3440 It still isn't really necessary to worry about this feature flag
3441 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
3444 Suppress message about an old-style fstab if the fstab file is empty.

3451 Change e2fsck to no longer clear the LARGE_FILES feature flag
3452 automatically, when there are no more > 2GB files in the filesystem.
3453 It's been almost a decade since there have been kernels that don't
3454 support this flag, and e2fsck clears it quietly without telling the
3455 user why the filesystem has been changed.

3508 print more intelligent error messages.
3510 Add a new function e2p_edit_feature2() which allows the caller to
3511 specify which feature flags are OK to set or clear, and which returns

3545 flushed when opening USB devices returned the error ENOMEDIUM.
3546 (Addresses Debian Bug: #463787)
3548 Added logic to the blkid library to automatically choose whether a
3549 filesystem should be mounted as ext4 or ext4dev, as appropriate.
3551 Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
3553 Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
3554 configured with --enable-jbd-debug.
3556 Document the BLKID_FILE environment variable in the libblkid man page
3561 Update e2fsprogs translation template and Vietnamese and Czech translations
3563 Fixed various Debian packaging issues --- see debian/changelog for
3564 details. (Addresses Debian Bugs: #436058)
3566 Don't try to create $DESTDIR/etc/init.d as part of make install as we
3567 don't install the init.d script (and it's not the recommended way to
3568 start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
3570 Use thread local storage to fix a theoretical race condition if two
3571 threads try to format an unknown error code at the same time in the
3575 E2fsprogs 1.40.5 (January 27, 2008)
3576 ===================================
3578 Fix a potential overflow big in e2image if the device name is too
3581 Mke2fs will now create new filesystems with 256 byte inodes and the
3582 ext_attr feature flag by default. This allows for much better future
3583 compatibity with ext4 and speeds up extended attributes even on ext3
3586 Teach e2fsck to ignore certain "safe" filesystem features which are
3587 set automatically by the kernel. Having the kernel set features
3588 automagically behind the user's back is a bad idea, and we should try
3589 to break the kernel of this habit, especially for the newer ext4
3590 feature flags. But for now, we will try to avoid needless full checks
3591 which can annoy users who are doing fresh installs.
3593 Add support in tune2fs and mke2fs for making a filesystem as being "ok
3594 to be used with test kernel code". This will be needed for using test
3595 filesystems with the latest ext4 kernel code.
3597 Change e2fsck -fD so that it sorts non-htree directories by inode
3598 numbers instead of by name, since that optimizes performances much
3599 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
3601 If e2image fills the disk, fix it so it exits right away instead of
3602 spewing large numbers of error messages.
3603 (Addresses-Sourceforge-Feature-Request: #606508)
3605 If ftruncate64() is not available for resize2fs, let it use ftrucate()
3606 instead, but have it check to see if the size would get truncated, and
3607 skip calling ftruncate in that case.
3609 Add support for detecting HFS+ filesystems in the blkid library.
3611 Add supprt in the blkid library for ext4/ext4dev filesystems.
3613 Fix a bug in blkid where it could die on a floating point exception
3614 when presented with a corrupt reiserfs image.
3616 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
3617 such that UUID string is a fixed length.
3619 Add sample python bindings for the uuid library to the contrib
3620 directory. (Addresses-Sourceforge-Patches: #778817)
3622 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
3623 will work with large files. (Addresses Sourceforge Feature Request:
3624 #1257500 and Sourceforge Support Request: #1253511)
3626 Allow the debugfs 'undel' command to undelete an inode without linking
3627 it to a specific destination directory, since this might require
3628 allocating blocks that could overwrite some yet-to-be-recovered
3629 deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
3631 Update Swedish translations from the Translation Project.
3636 Fix configure handling of --sbindir (which should rarely be used, but
3637 someone did complain, so let's fix it). (Addresses Sourceforge Bug:
3640 Updated e2fsprogs.spec file to include a new uuidd package
3642 Use pkg-config to determine where to find the devmapper library so we
3643 can find out where it is located on different distributions.
3645 Fix Makefile race so that "make -j3 distclean" works correctly
3647 Fix portability problems on non-Linux/non-Hurd/non-Masix systems,
3648 especially on MacOS X systems. (Addresses Sourceforge Bugs: #1861633,
3651 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3653 Fixed various Debian packaging issues --- see debian/changelog for
3654 details. (Addresses Debian Bugs: #459403, #459475, #459614)
3656 Remove the --enable-dynamic-static configure option, and build e2fsck
3657 dynamically by default. If the user wants e2fsck.static, he/she will
3658 need to build it via "make -C e2fsck e2fsck.static"
3660 Fix various build warnings due to missing prototypes.

3664 E2fsprogs 1.40.4 (December 31, 2007)
3665 ====================================
3667 Improve time-based UUID generation. A new daemon uuidd, is started
3668 automatically by libuuid if necessary. This daemon is setuid to allow
3669 updates to /var/lib/libuuid, so the clock sequence number can be
3670 stored and so if the clock is set backwards, it can be detected.
3671 (Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
3674 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
3675 superblocks. This avoids e2fsck from concluding that a full
3676 filesystem check is required before backing up the superblock due to
3677 changes in the feature flags. (Addresses Debian Bug: #454926)
3679 Fix fsck to only treat the '#' character as a comment at the beginning
3680 of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
3681 will cause fsck to issue an bogus warning message.
3682 (Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
3684 Format control characters and characters with the high eighth bit set
3685 when printing the contents of the blkid cache, to prevent filesystems
3686 with garbage labels from sending escape sequences to the user's screen
3687 that might, for example place it in graphics mode. (Addresses Ubuntu
3690 Fix sign-extension problem on 64-bit systems in in the com_err
3691 library. (Addresses Sourceforge Bug: #1809658)
3693 Avoid division by zero error when probing an invalid FAT filesystem in
3694 the blkid library. (Addresses Sourceforge Bug: #1831627)
3696 Update Dutch, Polish, and Vietnamese translations from the Translation
3697 Project. Remove the Rwandan translation upon advice of the
3698 Translation Project.
3703 Fix the libss "make check" regression test so that it works if the
3704 current directory is not in the user's path or if the libss shared
3705 library is not installed. (Addresses Sourceforge Bug: #1848974)
3707 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3708 (Addresses Debian Bugs: #444883, #441872)
3710 Fixed various Debian packaging issues --- see debian/changelog for
3711 details. (Addresses Debian Bugs: #437720, #451172, #458017)
3713 Fix build failure on non-Linux/non-Hurd/non-Masix systems.

3716 Fix Hurd portability issues. (Addresses Debian Bug: #437720)
3719 E2fsprogs 1.40.3 (December 5, 2007)
3720 ===================================
3722 Fix a potential security vulnerability where an untrusted filesystem
3723 can be corrupted in such a way that a program using libext2fs will
3724 allocate a buffer which is far too small. This can lead to either a
3725 crash or potentially a heap-based buffer overflow crash. No known
3726 exploits exist, but main concern is where an untrusted user who
3727 possesses privileged access in a guest Xen environment could corrupt a
3728 filesystem which is then accessed by the pygrub program, running as
3729 root in the dom0 host environment, thus allowing the untrusted user to
3730 gain privileged access in the host OS. Thanks to the McAfee AVERT
3731 Research group for reporting this issue. (Addresses CVE-2007-5497.)
3733 Fix hueristics in blkid which could cause a disk without partitions to
3734 be incorrectly skipped when a loopback device is present. (Addresses
3735 Red Hat Bugzilla #400321.)
3737 Fix e2image so that in raw mode it does not create an image file which
3738 is one byte too large.
3740 Change mke2fs's usage message so it recommends the preferred -E option
3741 instead of the deprecated -R option.
3743 Enhance the blkid library so it will recognize squashfs filesystems.
3744 (Addresses Red Hat Bugzilla #305151.)
3746 Enhance e2fsck so it will force the backup superblocks to be backed up
3747 if the filesystem is consistent and key constants have been changed
3748 (i.e., by an on-line resize) or by e2fsck in the course of its
3751 Enhance blkid's detection of FAT filesystems; so that USB disks with
3752 only a single bootable partition will not get missed.
3754 E2fsck will no longer mark a filesystem as invalid if it has time
3755 errors (i.e., if superblock mount time or last write time is in the
3756 future) and the user refuses to fix the problem.
3758 The Ubuntu init scripts don't properly set the system time correctly
3759 from hardware clock if the hardware clock is configured to tick local
3760 time instead of GMT time. Work around this as best as we can by
3761 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
3762 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
3765 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
3766 Hat Bugzilla #151533.)
3768 Fix e2fsck so that if the superblock is corrupt, but still looks
3769 vaguely like an ext2/3/4 superblock, that it automatically tries to
3770 fall back to the backup superblock, instead of failing with a hard
3773 Make the e2fsprogs program more robust so that they will not crash
3774 when opening a corrupt filesystem where s_inode_size is zero.
3776 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
3777 arguments are detected as such and the parse error is reported to the
3778 user. (Addresses Debian Bug #435381.)
3780 Change e2fsck so it will not complain if a file has blocks reallocated
3781 up to the next multiple of a system's page size.
3783 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
3784 about (valid) filesystems where the inode table extends to the last
3785 block of the block group. (Addresses Red Hat Bugzilla #214765.)
3787 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
3788 allocating inode tables for some relatively rare odd disk sizes.
3789 (Addresses Red Hat Bugzilla #241767.)
3791 Add Catalan translation and update Dutch and Swedish translations
3792 from the Translation Project.
3794 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
3795 still had an issue when trying to figure out whether we need to
3796 byte-swap fast symlinks that contained extended attributes.
3798 Fixed spelling mistakes, typos, and otherwise clarified man pages.
3799 (Addresses SourceForge Bug #1821333.)
3805 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
3807 Add "make check" to the RPM spec file
3809 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
3810 works correctly when the prefix is not the root directory.
3812 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
3813 clena up after themselves by deleting the test.img temporary file
3814 after completing the test.
3816 Fixed a corner case bug ext2fs_unlink() when trying to delete the
3817 first directory entry in a directory block and the last directory
3818 entry in the previous directory block is not in use. Fortunately
3819 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
3820 places where it is extremely unlikely to run into this corner case.
3822 Fix missing dependency which would cuase parallel builds to fail.
3823 (Addresses Sourceforge Bug #1842331.)
3825 Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
3826 calling open(O_CREATE) with a missing mode parameter.
3828 Fix the test_ss.c in lib/ss so it can be used as an example
3829 application program for the library as well as a regression test
3832 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
3833 are properly passed back up through the call stack.
3835 E2fsprogs 1.40.2 (July 12, 2007)
3836 ================================
3838 A recent change to e2fsck_add_dir_info() to use tdb files to check
3839 filesystems with a very large number of filesystems had a typo which
3840 caused us to resize the wrong data structure. This would cause a
3841 array overrun leading to malloc pointer corruptions and segfaults.
3842 Since we normally can very accurately predict how big the the dirinfo
3843 array needs to be, this bug only got triggered on very badly corrupted
3846 Fix a bug in e2fsck which caused it to incorrectly salvange
3847 directories when the last entry's rec_len is bogusly too big. This
3848 resulted in a nonsense filesystem corruption to be reported, and
3849 required a second run of e2fsck to fully fix up the directory.
3851 Update tune2fs man page to include more discussion of reserved blocks
3852 (Addresses Launchpad bug #47817)
3854 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
3858 E2fsprogs 1.40.1 (July 7, 2007)
3859 ===============================
3861 Fix bug which could cause libblkid to loop forever. When revalidating
3862 a partition where there is obsolete information in /etc/blkid.tab, we
3863 end up freeing a the type tag without clearing dev->bid_type, causing
3864 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
3866 The Turkish translation has a bug in it where it has the translation
3867 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
3868 @E, recursively, forever, until the stack fills up and e2fsck core
3869 dumps. We fix this by making e2fsck stop @-expansions after a
3870 recursive depth of 10, which is far more than we need.
3871 (Addresses Sourceforge Bug: #1646081)
3873 Compile the default mke2fs.conf into mke2fs program. People are
3874 getting surprised by mke2fs creating filesystems with different
3875 defaults than earlier versions of mke2fs if mke2fs.conf is not
3876 present. So we now create a built in version of mke2fs.conf file
3877 which is used by mke2fs if the /etc/mke2fs.conf is not present.
3878 (Addresses SourceforgeBug: #1745818)
3880 Improve the config/parse_types.sh helper script. Fix a potential
3881 security problem if e2fsprogs is built as root (as Gentoo does!). In
3882 addition fix the script and how it is called from the configure script
3883 so that it does the right thing when cross-compiling. (Fixes Gentoo
3886 Update Vietnamese, French, and Dutch PO files from the Translation
3887 Project. Also created a new e2fsprogs.pot file for translator.
3889 Fix bogus strip permission errors when building under Debian. When
3890 building the e2fsprogs dpkg's, the dh_strip command emits a large
3891 number of error messages caused by the permissions not being right.
3892 So run dh_fixperms before running dh_strip.
3897 Add new function: profile_set_default(). This function sets the value
3898 of the pseudo file "<default>". If the file "<default>" had
3899 previously been passed to profile_init(), then def_string parameter
3900 will be parsed and used as the profile information for the "<default>"
3903 Fix mk_cmds's error reporting so that it is unambiguous that it is the
3904 mk_cmds script which is generating the error. (Obviates Gentoo patch:
3905 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
3907 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
3908 priority" environment variable that overrides all others, where as
3909 LANG is the lowest priorty environment variable. If LC_ALL is set, it
3910 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
3911 the all the rest are set. This will assure that the locale when
3912 running the test suites is the "C" locale. (Obviates Gentoo patch:

3916 E2fsprogs 1.40 (June 29, 2007)
3917 ==============================
3919 Fix divide by zero error in blkid's NTFS probing logic.
3921 Add new blkid -g option which causes the blkid cache to be garbage
3924 Fix a bug in libblkid which could cause the internal field bid_type to
3925 become corrupted. Fortunately bid_type isn't used much, and bid_label
3926 and bid_uuid is only used by debugging code, so the impact of this bug
3929 Mke2fs will now store the RAID stride value when a filesystem is
3930 created with a requested RAID stride, and then use it automatically in
3933 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
3934 isn't too big. In some cases Lustre users have tried specifying an
3935 inode size of 4096 bytes, while keeping an inode ratio of one inode
3938 Improve sanity check in e2fsck's algorithm for finding a backup
3939 superblock, so that it won't accidentally find a superblock that was
3940 located in the journal, and then later reject it as being not a valid
3943 Fix e2fsck get_size logic so that it will work with the Linux floppy
3944 driver. The Linux floppy driver is a bit different from the other
3945 block device drivers, in that if the device has been opened with
3946 O_EXCL, it disallows another open(), even if the second open() does
3947 not have the O_EXCL flag. (Addresses Debian Bug: #410569)
3949 Fix error checking of badblock's last-block and start-block arguments.
3950 (Addresses Debian Bug: #416477)
3952 Fix e2fsck so that it doesn't overwrite the backup superblocks when
3953 recovering a journal until the master superblock has been confirmed as

3957 that a partition contains an NTFS filesystem, and fetch the UUID and
3958 LABEL information from NTFS filesystems. (Addresses Launchpad Bug:

3968 Fix e2fsck so that it updates the journal inode if it is corrupted and
3969 the backup journal information from the superblock was successfully
3970 used to recover the filesystem.
3972 Fix e2fsck so that it checks all of the blocks in the journal inode
3973 for validity. The original code only checked the direct blocks to
3974 make sure the journal inode was sane. Unfortunately, if some or all
3975 of the indirect or doubly indirect blocks were corrupted, this would

3980 Add extra sanity checks for extended attributes in the case where the
3981 size is zero but the offset is very large.
3983 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
3984 and ext2fs_get_next_inode_full().
3986 Clarify the copyright licenses used by the various libraries in
3987 the top-level COPYING file (Red Hat Bugzilla: 166058)
3989 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
3991 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
3993 Remove check in e2fsck which requires EA's in inodes to be sorted;
3994 they don't need to be sorted, and e2fsck was previously wrongly
3995 clearing unsorted EA's stored in the inode structure.
3997 Allow mke2fs or tune2fs to create a substantially larger journal (up
3998 to 10,240,000 blocks).
4000 Fix MD superblock detection, and make sure the correct UUID is
4001 reported from the MD superblock.
4003 Fix a signed vs. unsigned bug in debugfs.
4005 Enhance debugfs's date parser so that it accepts integer values.

4008 file with multiply claimed blocks is hard linked. or not at all if the
4009 root directory contains shared blocks
4011 Enhance debugfs so it can modify the block group descriptors using the
4012 command set_block_group_descriptor.
4014 Improve e2fsck's reporting of I/O errors so it's clearer what it was
4015 trying to do when an error happens

4038 Fix e2fsck to set the file type of the '..' entry when connecting
4039 a directory to lost+found. (Addresses Lustre Bug: #11645)
4041 Enhance e2fsck to recover directories whose modes field were corrupted
4042 to look like special files. This is probably only useful in
4043 artificial test cases, but it will be useful if we ever do the "inodes
4044 in directory" idea for ext4.
4046 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
4049 Fix resize2fs parsing of size parameter (in sector units). This was
4050 actually a bug in libe2p's parse_num_blocks() function. When handling
4051 the 's' suffix, it was ignoring the blocksize information passed in
4052 from the caller and always interpreting the number in terms of a 1k
4053 blocksize. (Addresses Debian Bug: #408298)

4062 memory utilization on really big filesystems. This uses the TDB
4063 library. See the [scratch_files] section of the e2fsck.conf man page

4114 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
4116 Device mapper scanning wasn't working in the blkid library because the
4117 pathnames had an extra "/dev" when they were being probed.
4119 Add GFS/GFS2 support to the blkid library.
4121 Fix blkid support of empty FAT filesystem labels.
4123 Avoid recursing forever (or for a long time) when the blkid library
4124 searches for a device and there are symlinks to directories in /dev.
4126 Avoid unaligned halfword access in blkid when accessing FAT
4127 superblocks, as this will cause Sparc/Solaris systems to throw a
4130 The latest devmapper libraries requires pthreads, add -lpthreads to
4131 the static link libraries for e2fsck.static if devmapper is enabled.
4132 (Addresses Debian bug: #388718)
4134 Improve the (non-installed, for experts only) findsuper program by
4135 printing the uuid and label from the superblocks, as well as the
4136 starting and ending offsets of the filesystem given the information in
4137 the superblock. Omit by default printing superblocks that are likely
4138 found in located in an ext3 journal unless an explicit -j option is
4141 Updated Spanish, French and Dutch translations and added Catalan
4142 translation. (Addresses Debian bug: #411562)
4144 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
4145 determining a partition's size, since binary searching to determine
4146 the device doesn't work on FreeBSD.
4148 Documentation about UUID's is available in enough places, and it's
4149 awkward to deal with debian-legal's insanities. So I'm caving in the
4150 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
4151 don't have do the dfsg tarball. Also remove the rule that only tried
4152 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
4153 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
4155 Fix the info-dir line so that the menu name does not contain a .info
4156 prefix. First of all, it's ugly, secondly, it causes the install-info
4157 command to fail to remove the com_err info file from the
4158 /usr/share/info/dir file when the comerr-dev package is removed and
4159 purged. (Addresses Debian Bug: #401711)
4161 Fixed spelling mistakes, typos, and otherwise clarified man pages.
4162 (Addresses Debian Bug: #369761, #373004, #379695)
4164 Fixed various Debian packaging issues --- see debian/changelog for
4165 details. (Addresses Debian Bugs #389554, #390664, #413208, #419605,
4166 #408352, #415560, #399155)
4172 E2fsck now supports the %It expansion when printing a problem report.
4173 It will print the type of the inode in the problem context.
4175 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
4176 (Addresses Sourceforge Bug: #1565561)
4178 Remove unused variables and other lint/gcc -Wall cleanups
4180 Add check to ext2fs_get_device_size() so it will return EFBIG for for
4181 filesystems contained in regular files where the filesystem image size
4182 is returned by stat64().
4184 Set local environment variables to C so mk_cmds and compile_et always
4185 work. (Addresses SourceForge Bug: #1532177)
4187 Added the 64-bit byte swapping function ext2fs_swab64().
4189 Added two new helper functions to prevent 2**31/2**32-1 overflow
4190 problems: ext2fs_div_ceil() and e2p_percent().
4192 Create new ext2fs library inline functions ext2fs_group_first_block()
4193 and ext2fs_group_last_block() in order to calculate the starting and
4194 ending blocks in a block group.
4196 Create the generated files read-only to remind developers not to edit them.
4198 Add support for autoconf 2.60 (with backwards compatibility for older
4199 versions of autoconf).
4201 Added an "make rpm" target to top-level Makefile
4203 Added various FreeBSD portability fixes.
4205 Exclude mercurial files from the RPM build tree to speed up copy/build.
4207 Use root_sysconfdir to define the locations of mke2fs.conf and
4208 e2fsck.conf instead of using a hard-coded /etc pathname.
4210 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
4212 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
4214 If diff -u is supported, use it to report test failures.
4216 Updates/improvements to RPM spec file
4218 Add on-disk format definitions for the following new features:
4219 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
4220 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
4221 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
4223 Add a new make target "checked-failed" in the tests directory which
4224 reruns any failed tests
4226 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
4228 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
4229 pointer dereferences, memory leaks, etc. None were security-criticial
4232 Fix up usage and decrement error messages in the test_icount program
4234 Add debugging code to the com_err library; if the environment variable
4235 COMERR_DEBUG is set to 1, print out debugging messages as error tables
4236 are added and removed from the com_err library. If the
4237 COMERR_DEBUG_FILE environment variable is set (and the process is not
4238 setuid) the debugging messages may be redirected to a file.
4240 Change all of the e2fsprogs programs to use the newer add_error_table()
4241 and remove_error_table() interfaces instead of the much older
4242 initialize_*_error_table() function.
4244 Add TDB support into the ext2fs library. This allows us to have a
4245 guaranteed library we can count on always being present so we can
4246 store data in an on-disk database.
4248 Add support for using TDB to store the icount data, so we don't run out
4249 of memory when checking really large filesystems.
4251 Change the regression test suite so that it skips empty test directories.
4253 Define the l_i_iversion field in ext2_inode. The l_i_version field is
4254 now defined from the old l_i_reserved1 field in the ext2 inode. This
4255 field will be used to store high 32 bits of the 64-bit inode version
4258 Add Makefile production rule for e2fsprogs.spec in case it gets
4261 Add new function profile_get_uint() to allow for a clean way to fetch
4262 unsigned integers from the context.
4264 Add test to make sure the ext2 superblock structure is 1024 bytes.
4266 Fix typo in name of f_dup4 regression test
4268 Add new function blkid_gc_cache() which performs a garbage collection
4269 pass on the /etc/blkid.tab file.
4271 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
4272 general, only e2fsck (after the filesystem is clean), tune2fs, and
4273 resize2fs should change the backup superblocks by default. Most
4274 callers of ext2fs_open() should not be touching any superblock fields
4275 which require the backups to be touched.
4277 Add new function to libext2fs, ext2fs_default_journal_size(), which
4278 returns the default journal size.
4281 E2fsprogs 1.39 (May 29, 2006)
4282 =============================
4284 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
4285 between 2**31 and 2**32 blocks.
4287 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
4288 configure the filesystem features, blocksize, and inode_ratio for
4289 different filesystem types.
4291 Mke2fs will now create filesystems hash trees and on-line resizing
4292 enabled by default, based on the new /etc/mke2fs.conf file.
4294 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
4295 filesystem device node in exclusive mode to prevent accidents by
4296 system administrators. In the case of resize2fs and mke2fs, it will
4297 only use exclusive mode if the filesystem is not mounted.
4299 Fixed a bug in mke2fs which caused it to to fail when creating the
4300 resize inode for large filesystems. (Addresses Debian Bug #346580)
4302 When allocating space for the RAID filesystems with the stride
4303 parameter, mke2fs will now place each portion of the group's inode
4304 table right up after the superblock (if present) in order to minimize
4305 fragmentation of the freespace.
4307 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
4308 efficiently by writing the inode and block bitmaps in one pass, thus
4309 reducing the number of disk seeks required.
4311 Add support for on-line resizing to resize2fs.
4313 Fix blkid library so that logic to determine whether or not a device's
4314 cached information in /etc/blkid.tab needs to be verified or not
4315 doesn't get confused by a system clock which is insane (for example,
4316 if the battery is dead on a Macintosh running PPC Linux. (Addresses
4317 Red Hat Bug: #182188)
4319 The blkid library will now store the UUID of the external journal used
4320 by ext3 filesystems, so that in the future, the userspace mount binary
4321 can use this to find the location of the external journal and pass
4322 this information to the kernel.
4324 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
4325 control how various options should be handled. See the e2fsck.conf
4326 man page for more details. (Addresses Debian Bug: #150295)
4328 E2fsck now prints an explanatory message when delaying a filesystem
4329 check when the system is running on battery. (Addresses Debian Bug:
4332 E2fsck will detect if the superblock's last mount field or last write
4333 field is in the future, and offer to fix if so. (Addresses Debian Bug
4334 #327580) These problems will be fixed automatically in preen mode
4335 since Debian's boot sequence bogusly doesn't set the time correctly
4336 until potentially very late in the bootup process, and this can cause
4337 false positives which will cause users' systems to fail to boot.
4338 (Addresses Debian Bugs #343662 and #343645)
4340 E2fsck now checks to see if the superblock hint for the location of
4341 the external journal is incorrect, and if so, offer to update it.
4342 (Addresses Debian Bug: #355644)
4344 Fix e2fsck from segfaulting on disconnected inodes that contain one or
4345 more extended attributes. (Addresses Debian Bug: #316736, #318463)
4347 E2fsck will stop and print a warning if the user tries running a
4348 read/write badblocks test on a read-only mounted root filesystem.
4350 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
4351 C. Thompson for pointing these out; they were originally found using
4354 When resizing a file containing a filesystem, resize2fs will expand or
4355 truncate a file as necessary. (Addresses Debian Bug: #271607)
4357 Resize2fs will now automatically determine the RAID stride parameter that
4358 had been used to create the filesystem, and use that for newly created
4359 block groups. The RAID stride parameter may also be manually specified
4360 on the command line using the new -S option to resize2fs.
4362 Fix mke2fs so that it correctly creates external journals on
4363 big-endian machines (such as a S/390).
4365 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
4366 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
4367 Chambraud for pointing this out.)
4369 Dumpe2fs will now print the size of the journal (if present).
4371 Fix debugfs's set_inode_field command so it can properly set the frag,
4372 fsize, uid_high, gid_high, and author fields in the inode instead of
4373 silently failing, and so that setting the i_size actually sets i_size
4376 Add a new debugfs command, set_current_time, which sets fs->now so
4377 that regression test suites can repeatedly modify the filesystem's
4380 Fix a bug in debugfs's icheck which would incorrectly report the owner
4381 of an extended attribute block.
4383 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
4384 print a usage message when an illegal option character is given.
4386 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
4387 so it won't core dump. (Addresses SourceForge bug #1424311)
4389 Fix mklost+found so that it creates a full-sized directory on
4390 filesystems with larger block sizes.
4392 Fix a file descriptor leak in blkid library.
4394 Fix a display bug in "badblocks -sv" so that the done message properly
4395 clears the block number at the end of the test. (Addresses Debian Bug
4398 Allow fractional percentages to the -m option in mke2fs and tune2fs
4399 (Addresses Debian Bug: #80205)
4401 Use fstat/fstat64 in getsize.c if the the target is a regular file,
4402 instead of attempting to do a binary search. Fix some fd leaks in
4405 Add support for device mapper library to the blkid library to ensure
4406 that the "best" (i.e., leaf) device is probed by the blkid library.
4408 Fix the blkid library so that it notices when an ext2 filesystem is
4411 Improve the blkid's library VFAT/FAT detection; it now understands
4412 labels stored in the root directory, and is more paranoid about
4413 checking the FAT superblock values.
4415 Fixed a fd leak in the uuid library which was causing problems for the
4416 LVM tools. (Addresses Debian Bug: #345832)
4418 Add support for the reiser4 and software suspend partitions to the
4419 blkid library. Also add support for extract the label from iso9660
4422 Fix a compile_et bug which miscount the number of error messages if
4423 continuations are used in the .et file.
4425 Add extra sanity checks to protect users from unusual cirucmstances
4426 where /etc/mtab may not be sane, by checking to see if the device is
4427 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
4430 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
4431 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
4433 Fix use-after-free bug in e2fsck when finishing up the use of the
4434 e2fsck context structure.
4436 Fixed spelling mistakes, typos, and otherwise clarified man pages and
4437 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

4450 Update config.guess and config.sub to latest version (2006-02-23) from
4453 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
4454 Bugs: #360661, #360317)
4456 Fixed the Makefile so that they work correctly on newer versions of
4457 GNU make (i.e., 3.81).
4459 Add valgrind support to the regression test suites, and eliminate
4460 false positives from valgrind.
4462 Add a regression test suite for the blkid library.
4464 Fix a fencepost error in resize2fs caught by valgrind.
4466 Fix compiler warnings about missing memcpy prototypes.
4468 We no longer have the sparc assembly code in the header file any more,
4469 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
4470 break compiles on the sparc architectures when using gcc.
4472 In the libext2fs library, add the new field fs->now which if non-zero
4473 is used instead of the system time when setting various filesystem
4474 fields (last modified time, last write time, etc.)
4476 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
4477 ext2fs.h which is needed since the inline functions use memcpy().
4478 (Addresses Sourceforge Bug #1251062)
4480 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
4481 the build system when building files in the util directory which are
4482 needed during the build process. This avoids potential problems when
4483 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
4484 are not recognized as valid by the host compiler. (Addresses
4485 Sourceforge Bug #1261547)
4487 Clean up the blkid library by making the superblock and generic i/o
4488 functions to be more generic. Clean up interface to the probe
4489 function, and fix memory leak. Finallly, remove an unneeded reference
4490 to probe.h in the lib/blkid/resolve.c
4492 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
4493 of invalid block #'s.
4495 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
4496 indicate that the the function read/writes the memory location.
4498 Fix various gcc -Wall complaints.
4500 Add a dependency to make sure that the subdirectories are created
4501 before creating all of the object files, in order to address parallel
4502 build problem in the library Makefiles. (Addresses Sourceforge Bug:
4505 Add $(LDFLAGS) to the command line argument when generating an ELF or
4506 Solaris shared library, to allow cross-compile and other builds that
4507 might need to specify -L paths to needed libraries. (Addresses
4508 Sourceforge Bug #1261549)
4510 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
4511 intended for testing purposes. It allows an ext2/ext3 developer to
4512 create very large filesystems using sparse files where most of the
4513 block groups are not initialized and so do not require much disk
4514 space. Eventually it could be used as a way of speeding up mke2fs and
4515 e2fsck for large filesystem, but that would be best done by adding an
4516 RO_COMPAT extension to the filesystem to allow the inode table to be
4517 lazily initialized on a per-block basis, instead of being entirely
4518 initialized or entirely unused on a per-blockgroup basis.
4520 Fix backwards compatibility so e2fsprogs will better compile on Linux
4523 Make test scripts more robust against locale-related environment variables
4525 Fix type warning problem with sizeof() in ext2fs_open2().
4527 Fix type warning problem with time_t in debugfs.
4530 E2fsprogs 1.38 (June 30, 2005)
4531 ==============================
4533 Fix blkid's test programs (built with "make check") compile correctly
4534 even without "configure --enable-blkid-debug".
4536 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
4537 type aliasing rules on newer gcc compilers. (Addresses Red Hat
4540 Fix com_err library to make it more compatible with recent changes
4541 made to the com_err library in MIT Kerberos V5 version 1.4.
4542 (Addresses Sourcefroge Bug #1150146)
4544 General cleanup of messages printed by e2fsprogs programs for grammar,
4545 consistency, and to make life easier for translators. Fixed a few
4546 strings containing English that had not been marked as needing
4547 translations. Removed strings that do not need to be translated, to
4548 make life easier for translators.
4550 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
4551 test to see if a device appears to be in use instead of just relying
4552 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
4554 Fix portability problem in the filefrag program affecting platforms
4555 where the size of an integer is smaller than the size of a long.
4556 (Addresses Debian Bug #309655)
4558 Mke2fs will now use a larger journal by default for filesystems
4559 greater than 4GB. (128 MB instead of 32MB).
4561 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
4562 unless forced. This is to avoid signed vs. unsigned kernel bugs in
4563 block numbers that still need to be fixed.
4565 The blkid program has a new option which will more efficiently search
4566 for device when it is known (or expected) that only one matching
4567 device will be found in the system, such as when doing a lookup by
4570 Debian's e2fsprogs-specific initrd fragment will avoid including
4571 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
4572 and LD_LIBRARY_PATH, and filtering out libraries found in
4573 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
4575 Fixed a potential portability issue in the blkid programs for
4576 architectures where the char type is unsigned. (Addresses Sourceforge
4579 Fix a bug in filefrag so that it doesn't falsely count an extra
4580 discontinuity when the first block found is an indirect block.
4581 (Addresses Debian Bug #307607).
4583 Fix blkid's recognition of cramfs filesystems, and enhance it to be
4584 able to handle cramfs labels.
4586 Fix debugfs's stat command to not core dump when a filesystem is not
4589 Fix e2fsck's handling of error conditions caused by the resize inode
4590 claiming blocks that are also used by other inodes, a filesystem
4591 corruption which was commonly caused by a bug in Fedora Core 3's
4594 Fixed bug in filefrag which caused it to fail on non-ext2/3
4595 filesystems. (Addresses Debian Bug: #303509)
4597 If the superblock last mount time indicates that the system clock may
4598 not be accurate, then e2fsck will omit checking inodes' deletion time
4599 field for indications of a potential corrupted orphaned inode list.
4600 (Previously e2fsck only ommited these LOW_DTIME checks when the
4601 superblock's last write time looked insane.)
4603 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
4604 (Addresses Debian bug #302200)
4606 Make the blkid library more paranoid about being run from setgid
4607 programs, and to use __secure_getenv() from libc if it is available.
4609 Fixed spelling mistakes, typos, and otherwise clarified man pages.

4613 Updated and fixed translations.
4615 Fixed various Debian packaging issues --- see debian/changelog for
4621 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
4622 changed to take an unsigned int for the bit number. Negative bit
4623 numbers were never allowed (and didn't make any sense), so this should
4624 be a safe change. This is needed to allow safe use of block numbers
4625 greater than or equal to 2**31.
4627 The compile_et program will avoid recreating generated foo_err.c and
4628 foo_err.h files if no changes are necessary. The compile_et program
4629 will also atomically replace these files to avoid a potential parallel
4630 build race problem on SMP systems. (Addresses Sourceforge Bug:
4633 Added a new function to the blkid library, blkid_probe_all_new(),
4634 which only probes newly added disk devices, and change
4635 blkid_find_dev_with_tag() to use this function so that when a
4636 requested tag is not found, devices that were previously not checked
4637 are searched before searching all devices in the system.
4639 Added new functions to the blkid library, blkid_dev_set_search() and
4640 blkid_dev_has_tag().
4642 E2fsck's problem strings can now use @m and @n as abbrevations for
4643 "multiply-claimed" and "invalid", respectively.
4645 The e2fsprog.pot file now has an explanation of how the @-expansion
4646 and %-expansion works, and strings in e2fsck/problem.c which contain @
4647 characters now have comments in e2fsprogs.pot with the @-expansion to
4648 make life easier for translators.
4650 Fixed missing return values in the ext2fs library which could cause it
4651 to return random garbage in certain error conditions.
4653 Allow the current time to be overriden via the E2FSCK_TIME environment
4654 variable for use in regression tests.

4669 E2fsprogs 1.37 (March 21, 2005)
4670 ===============================
4672 Add support for checking the validity of Extended Attributes stored in
4675 Add support for dumping the contents of large inodes to debugfs,
4676 including the extended attributes stored in inodes.
4678 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
4679 when we create a new inode we make sure that the extra information in
4680 the inode (any extra fields in a large inode and any ea-in-inode
4681 information) is initialized correctly. This can take place when
4682 mke2fs creates the root and lost+found directory, when e2fsck creates
4683 a new root inode or a new lost+found directory, and when the user uses
4684 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
4685 create inode could inherit garbage (or old EA information) from a
4686 previously deleted inode.
4688 Fixed a bug in e2fsck so it would notice if a file with an extended
4689 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
4692 Added support to filefrag to detect files which are using the new
4693 experimental file extents format, and use the non-ext2 algorithm in
4694 that case. Fixed a bug to avoid reporting a false discontinuity if
4695 there is one or more unallocated blocks at the beginning of a file.
4697 Duplicated a check for noticing whether or not the number of blocks
4698 (given a certain blocksize) is greater than 2**32 when the
4699 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
4700 allows mke2fs to automatically use a larger blocksize when creating a
4701 filesystem on a very large device when run on systems that do not
4702 support BLKGETSIZE64.
4704 Fix the I18N build which was broken in e2fsprogs 1.36 because the
4705 build system had been switched to treat the .gmo files as shipped
4706 files (for backwards compatibility with systems that have older GNU
4707 I18N tools installed), but the gen_tarball.in script was still
4708 removing the .gmo files from the official source distribution.
4710 Fixed various Debian packaging issues --- see debian/changelog for
4711 details. (Addresses Debian Bugs ##296769, #299341)
4716 Added new functions to the e2p library which convert between a string
4717 and os_type: e2p_os2string() and e2p_string2os(), and used them to
4718 make the generated binaries more compact.
4720 Fixed a compile-time error on Darwin systems.
4722 Cleaned up the lib/ext2fs Makefile slightly.
4725 E2fsprogs 1.36 (February 4, 2005)
4726 =================================
4728 All of the patches that were applied to Fedore Core 3's
4729 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
4730 lot of bug fixes first. Users of Fedora Core 3 are strongly
4731 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
4733 Add support for filesystem with the online resizing via resize inode
4734 feature. Fixed numerous bugs from the Fedora patches. The Fedora
4735 patches also didn't bother to do any consistency checking on the
4736 resize inode, or add any tests to the regression test suite. The "-R
4737 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
4738 being listed in mke2fs's usage message. All of these shortcomings
4739 have been corrected.
4741 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
4742 program. In order to do this, the user must run the commands:
4744 debugfs -w /dev/hdXXX -R "features ^resize_inode"
4745 e2fsck -f /dev/hdXXX
4747 Optionally, the ext2prepare command can be used to re-enable online
4748 resizing after the filesystem has been fixed.
4750 The fsck program will now accept an optional filedescriptor argument
4751 to the -C option. (The Fedora version of this patch would sometimes
4752 cause fsck to ignore a parameter on fsck's command line in some rare
4755 Make sure e2fsprogs doesn't write garbage into the reserved portion of
4758 Make sure resize2fs releases the blocks belonging to the old inode
4759 table blocks when moving the inode table. (Addresses Debian Bug:
4762 Skip the r_resize_inode test if resize2fs is not compiled (due to
4763 configure --disable-resizer)
4765 E2fsck now checks the summary filesystem accounting information, and
4766 if any of the information is obviously wrong, it will force a full
4767 filesystem check. (Addresses Debian Bug #291571)
4769 Fix e2fsck to not complain when the resize_inode feature is enabled,
4770 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
4773 Fix e2fsck to note delete symlinks that contain an extended attribute
4774 after the ext_attr feature flag has been cleared. (Addresses Red Hat
4777 Add new utility program, copy_sparse.c, which is very useful
4778 for dealing with large sparse files (such as e2image files).
4780 Add support for jnl_blocks[] for debugfs's set_super_value.
4782 Fix filefrag so that it works correctly with sparse files.
4784 Filefrag -v will print first and last blocks.
4786 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
4789 Add mke2fs support so that it can support filesystems larger than 4TB
4790 automatically, by retrying with a 4k blocksize if the device size is
4791 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
4794 Change blkid to test for NTFS first because Windows sometimes doesn't
4795 clear enough of the parition to confuse the probing routines into
4796 thinking the old filesystem type is still valid. (Addresses Debian
4799 Add support for swap partition label and uuid's in the blkid library.
4801 Add support to the blkid library to recognize Oracle ASM volumes.
4803 Make blkid -t display all devices that match the specified criteria,
4804 not just the first one, and work more consistently when the blkid
4805 cache file is not available or set to /dev/null. (Addresses Debian
4806 Bug #290530 and #292425)
4808 Badblocks will now correctly display block numbers greater than
4809 999,999,999 in its progress display.
4811 The tune2fs program will not allow the user from setting a ridiculous
4812 number of reserved blocks which would cause e2fsck to assume the
4813 superblock was corrupt. E2fsck's standards for what is a ridiculous
4814 number of reserved block has also been relaxed to 50% of the blocks in
4817 The blkid library will return vfat in preference to msdos, and ext3 in
4818 preference to ext2 (if the journalling flag is set) so that mount will
4819 do the right thing. (Addresses Debian bug #287455)
4821 Mke2fs will now use the -E option for extended options; the old -R
4822 (raid options) option is still accepted for backwards compatibility.
4823 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
4825 Mke2fs will now accept a size in megabytes, gigabytes, and other units
4826 (via "32m" or "4g" on the command line) if the user finds this more
4827 convenient than specifying a block count.
4829 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
4830 cache conherency problem.
4832 Debugfs now supports a new command, set_inode_field, which allows a
4833 user to manually set a specific inode field more conveniently, as well
4834 as set entries in the indirect block map.
4836 Debugfs's set_super_value command has been enhanced so that the user
4837 can set most superblock fields, including the date/time fields and
4838 some of the more newsly added superblock fields.
4840 E2fsprogs programs now accept an offset to be passed to the file
4841 specifiers, via the syntax: "/tmp/test.img?offset=1024".
4843 E2fsprogs programs will now accept blocksizes up to 65536; kernel
4844 support on the x86 doesn't exist for now, but it can be useful on
4845 other architectures with page sizes greater than 4k. There are 2.6
4846 kernel patches out there which enable this, but they are of this
4847 writing still experimental.
4849 The e2image command now takes the -s option which will scramble
4850 directory entries for raw image files.
4852 Fix a file descriptor leak in the filefrag program.
4854 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
4857 Fix bug in debugfs where kill_file would lead to errors when deleting
4858 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
4860 Fix bug in the blkid library when detecting the ocfs1 filesystem
4862 Remove obsolete EVMS 1.x and a.out DLL support.
4864 E2fsck will attempt to recover from a journal containing illegal blocks.
4866 Fixed two potential ordering constraint problems in e2fsck which might
4867 cause the filesystem to be corrupted if e2fsck is interrupted during a
4868 (extremely narrow) race window. Thanks to Junfeng Yang from the
4869 Stanford Metacompilation group for pointing this out.
4871 Fixed bug in e2fsck where it would not accurately detect whether or
4872 not the system is running on adaptor if the ACPI device representing
4873 the AC adapter didn't correspond to the what was used on IBM
4876 Change e2fsck to accept directories greater than 32MB.
4878 Fix e2fsck so that a checkinterval of zero disables a time-based check
4881 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
4882 to the PAGER environment variable. (Addresses Debian Bug #239547)
4884 Tune2fs will not mark rewrite the superblock if the feature bitmasks
4887 The debugfs program will set the filetype information when creating a
4890 Add debugfs -d option to use a separate source of data blocks when
4891 reading from an e2image file.
4893 Add e2image -I option which allows the e2image metadata to be
4894 installed into a filesystem.
4896 Fixed bug in the badblocks program which caused "done" to always
4897 appear in english even when a translation was available. (Addresses
4900 The blkid program has a new option -o which controls the output format
4901 of the blkid program; this is makes blkid more convenient to use in
4904 Fix a minor bug in uuid library, which was not using the full 14 bits
4905 of clock sequence when generating UUID's.
4907 Fix a Y8.8888K problem in the uuid library.
4909 Logsave now creates a new session id for itself to avoid getting
4910 killed by init whan transitioning between init levels.
4912 Change the licensing of the UUID library to be the 3-clause BSD-style
4913 license; this allows Apple to use the uuid library in Darwin.
4915 Add ocfs and ocfs2 probe support into the blkid library.
4917 Fix a memory and file descriptor leak in the blkid library.
4919 The blkid library will revalidate the device if the system time is
4920 earlier than last verification time of the device, since that
4921 indicates that the system time is probably nottrustworthy.
4923 The blkid library will override the default location of the blkid.tab
4924 file by the BLKID_FILE environment variable, if it is available.
4926 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
4928 Add various portability fixes for lame new versions of glibc, Darwin
4929 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
4930 Bugs #239934, #264630, #269044, #255589, #289133)
4932 Add support for Windows 9x/NT under Cygwin.
4934 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
4935 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
4937 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
4939 Update the rpm spec files so that it works better with Fedora core 2
4942 Fixed various Debian packaging issues (see debian/changelog). In
4943 particular, fixed the Debian initrd scripts. (#241183, #248050,
4950 Fixed various gcc -Wall warnings.
4952 The uuid library now has new functions uuid_unparse_upper() and
4953 uuid_unparse_lower() which forces the case of the hex digits to be
4954 upper case, or lower case.
4956 The build process has been speeded up by enhancing the subst program
4957 to update the modtime on the generated files even when the generated
4958 file hasn't changed.
4960 The uuid library now uses C99 stdint.h types instead of custom types.
4962 Updated config.guess and config.sub with newer versions from the FSF.
4964 Removed out of date .cvsignore files from the source distribution.
4966 The ext2fs_unlink() function will return an error if both the name and
4967 inode number are unspecified, to avoid doing something surprising
4968 (such as unconditionally deleting the first directory entry).
4969 Directory entries are now deleted by coalescing them with the previous
4970 directory entry if possible, to avoid directory fragmentation. This
4971 is not an issue with the e2fsprogs suite, but may be a problem for
4972 some of the users of libext2fs, such as e2tools.
4974 Add support for version numbers of the form "1.36-rc1".
4976 Fix build of mke2fs.static.
4978 Add basic ext2fs library support for large (EA in inode) inodes.
4980 The test_io mechanism can now abort after n reads or writes to a
4981 particular block. The block is specified by TEST_IO_BLOCK environment
4982 variable, and the read/write count by the TEST_IO_READ_ABORT and
4983 TEST_IO_WRITE_ABORT environment variables. The block data is now only
4984 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
4986 UUID_DEFINE() in the uuid library now creates a static variable, with
4987 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
4988 be used in header files.
4990 Add support for the install-strip and install-shlibs-strip targets, as
4991 suggested by the GNU coding guielines. "make install" no longer
4992 strips the binaries which are installed.
4994 Remove support for the --enable-old-bitops configure option which was
4995 only for very old sparc systems.
4997 Remove support for --enable-clear-htree; this was only needed during
4998 the early development of the htree patch.
5000 Use Linux-kernel-style makefile output so it is easier to see compiler
5003 Update gettext files to version 0.14.1.
5005 Update to use autoconf 2.5x.
5007 Improved support for compiling e2fsprogs under dietlibc.
5009 Make e2fsprogs portable to Solaris and FreeBSD systems.
5011 Add blkid_verify(), blkid_get_library_version(), and
5012 blkid_parse_version_string() functions to the blkid library.
5014 Add pkg-config files for e2fsprogs's libraries.
5016 Fix "make uninstall" to so that it removes everything that is installed.
5018 Add a configure --enable-maintainer-mode option which enables the
5019 makefile rules to rebuild the configure script from configure.in, and
5020 to reubuild the .gmo files in po directory.
5022 Drop the sparc assembly bitwise operations; it's less efficient
5023 than the GCC 3.4 compile code and triggers compiler warnings on
5024 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
5025 (Addresses Debian Bug #232326)
5028 E2fsprogs 1.35 (February 28, 2004)
5029 ==================================
5031 E2fsck has a new -k option, which in conjunction with the -c options,
5032 preserves the existing badblocks list.
5034 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
5036 E2fsprogs will now deal correctly with symlinks that contain
5037 extended attribute information, which can be created using SE Linux.
5038 (Addresses Debian Bug #232328)
5040 Remove a double longjump into an invalid stack frame bug in e2fsck.
5041 (This was during an abort sequence, which normally worked on Linux and
5042 caused a core dump on other operating systems.)
5044 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5045 (the NLS library will replace "" with the .po header information).
5047 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
5048 dump due to a division by zero error. (Addresses Debian bug #207082)
5050 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
5051 when reconnecting a directory requires creating a lost+found
5052 directory. (Addresses Debian bug #219640).
5054 Fixed a bug where e2fsck would bomb out if a journal needed to be
5055 replayed when using an alternate superblock.
5057 E2fsck will give an extra grace period before actually forcing a check
5058 if the laptop is running on battery. The next time fsck runs while
5059 the system is on the AC mains, or after the grace period is exceeded,
5060 the filesystem will be checked. (Addresses Debian bug #205177)
5062 E2fsck will inform the user when there are 5 or fewer mounts before a
5063 filesystem check will be forced. (Addresses Debian bug #157194)
5065 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
5066 We now correctly handle the case where there is an overlap between a
5067 block group descriptor or a superblock and a bad block indirect block.
5068 In the case where the indirect block is corrupted, we now suggest
5071 Fix byte swap bugs in e2fsck that caused the journal backup location
5072 in the superblock and symlinks created by SE Linux to be cleared
5073 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
5075 E2fsck -c now replaces the current list of bad blocks with the ones
5078 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
5079 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
5081 Fix a potential bug in e2fsck which could cause it to core dump when
5082 trying to print the location of the backup superblock.
5084 Protect against a potential core dump in e2fsck when printing a
5085 message about backup superblocks.
5087 Add support for backing up the journal inode location in the
5088 superblock. E2fsck will automatically save the journal information in
5089 the superblock if it is not there already, and will use it if the
5090 journal inode appears to be corrupted. ext2fs_add_journal_inode()
5091 will also save the backup information, so that new filesystems created
5092 by mke2fs and filesystems that have journals added via tune2fs will
5093 also have journal location written to the superblock as well.
5094 Debugfs's logdump command has been enhanced so that it can use the
5095 journal information in the superblock.
5097 E2fsck will now update all superblocks when moving the journal inode.
5099 Shrink the size of the e2fsck executable by moving some initialized
5100 variables to the BSS segment.
5102 E2fsck will avoid printing the ^A and ^B characters which bracket the
5103 progress bar when stdout and stdin are a tty device instead of a pipe
5104 to another program. (Addresses Debian bug #204137)
5106 Debugfs's mkdir command will automatically expand the directory if
5107 necessary. (Addresses Debian Bug: #217892)
5109 Fixed a bug in debugfs so that copying a file from /dev/null uses the
5110 correct mode bits. (Addresses Debian Bug: #217456)
5112 If the environment variables DEBUFS_PAGER and PAGER are not set,
5113 debugfs now searches for the appropriate pager to use, beginning with
5114 /usr/bin/pager, and then falling back to 'more' and 'less'.
5115 (Addresses Debian bug #221977)
5117 Debugfs will now support 2.6 device numbers where the major or minor
5118 number may be larger than 255. (Addresses Sourceforge bug #865289)
5120 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
5122 Chattr now stops processing options when it sees '--'. (Addresses
5125 Fix regression tests so they work correctly when e2fsprogs is compiled
5126 with configure --disable-htree.
5128 Fix bug in uuid library when there is no network card and the library
5129 is generating a time-based uuid. The random MAC address was not
5130 correctly generated to be a multicast address.
5132 Add compile_et extensions from Heimdall that were missed the first time
5135 Fix bug in badblocks when using O_DIRECT; we need to make sure that
5136 we're reading from an offset which is page aligned. For read-only and
5137 read-write tests, we try to recover after an error so that we can
5138 continue reading on page-aligned boundaries. (Addresses Debian Bug
5141 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
5144 Updated and clarified various man pages. (Addresses Debian Bug
5145 #206845, #222606, #214920, #232406)
5147 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
5149 Fixed various Debian packaging issues (see debian/changelog).
5154 Fixed a build problem so that e2fsprogs would compile with the
5155 --enable-profile option to configure selected. (Addresses Sourceforge
5158 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
5159 Bugzilla Bug #112448)
5161 Centralize code which calculates the location of the superblock
5162 and block group descriptors so that it is in a single library routine.
5164 Added two new functions, ext2fs_file_open2() and
5165 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
5167 Fix compile_et to output the correct prototype for
5168 initialize_xxx_err_table_r() in the header file. (Addresses Debian
5171 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
5173 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
5174 present. This is for when we try stuffing an int into void * pointer.
5176 Fix type-punning which can cause gcc 3.x to miscompile code by getting
5177 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
5178 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
5179 **'. The EVMS code uses an ugly union approach since we don't want to
5180 modify the EVMS interfaces.
5182 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
5183 aid build process on systems can use invoke GNU make as "gmake".
5185 Added regression testing for mke2fs.
5187 Fixed gcc -Wall nitpicks.
5189 Fixed various compiler warnings.
5191 Add portability fixes for FreeBSD and for using fsctl under Darwin to
5192 support ext2 ioctl's.
5195 E2fsprogs 1.34 (July 25, 2003)
5196 ===============================
5198 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
5199 a tight loop while waiting for a child fsck to exit in some cases.
5200 This burns CPU times which slows down the low-level filesystem check.
5202 Added code to mke2fs to assure that the default block size for a
5203 filesystem is at least as big as the sector size of the device, if it
5206 Changed mke2fs and resize2fs to round the default size of a filesystem
5207 to be an even multiple of the VM pagesize in order to avoid a Linux
5208 kernel bug introduced when the storage of the buffer cache was moved
5209 into the page cache.
5211 Mke2fs will warn the user when creating a filesystem with journaling
5212 and a blocksize greater than 4096. (Addresses Debian bug #193773)
5214 Fixed a bug in resize2fs which caused it to fail on filesystems with a
5215 non-empty bad block list. Resize2fs now discards any blocks on the
5216 badblock list which are no longer part of the filesystem as the result
5217 of a filesystem shrink. (Note: this means that shrinking and then
5218 enlarging a filesystem is no longer a reversible operation;
5219 information about bad blocks in the part of the filesystem which is to
5220 be chopped off will be lost.)
5222 Changed resize2fs so the user can use prefixes to specify the units of
5223 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
5224 and to make the error and informational messages explicitly display
5225 the blocksize used by the filesystem, in order to avoid confusion.
5226 (Addresses Debian bug: #189814)
5228 Added a new debugfs command, dump_unused, which dumps the contents of
5229 all unused blocks to stdout. (Useful as an emergency try-to-find
5230 deleted data command.)
5232 Added a new debugfs command, imap, which prints the location of a
5233 specified inode in the inode table.
5235 Fixed a bug in the badblocks program which caused it to use one bit of
5236 randomness in its non-destructive read/write test, instead of using a
5237 full 8 bits of randomness.
5239 Added a new option (-t) to badblocks, which allows the user to control
5240 the test pattern(s) used when checking a disk.
5242 The blkid probe function now more correctly detects UDF filesystems.
5244 Fixed a bug in the blkid library which caused it to not update its
5245 cache if a filesystem changes from having a label to not having a
5248 Fixed a bug in the blkid library wihch could avoid an infinite loop
5249 in blkid_find_dev_with_tag() if /proc is not mounted and there the
5250 /etc/blkid.tab file has not yet been created.
5252 Fixed the badblocks program so that the destructive read/write test
5253 honors the -c option, and to use O_DIRECT when possible to avoid
5254 thrashing the system block buffer cache.
5256 Fixed various NLS issues.
5257 - Added Czech and Swedish translations
5258 - Removed testing NYC translation
5259 - Fixed NLS support for message abbrevations in e2fsck
5260 - Remove de-utf.po, since we shouldn't have two versions using different
5262 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
5263 simplify the statistics reporting in e2fsck.
5265 Changed configure.in so that its defaults for *BSD systems no longer
5266 build an fsck wrapper, and not to install in /usr/local by default.
5268 Fixed some minor spelling errors/typo's in e2fsck and the configure
5271 Fixed various Debian packaging issues (see debian/changelog).
5273 Updated and clarified man pages. (Addresses Debian Bug #195616)
5278 Fix gcc -Wall nitpicks.
5280 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
5281 NLS support by default. (Added partial workaround for gettext/Darwin
5282 incompatibility problems.)
5284 Added full MIT KRB5 and Himdall compaibility support to the com_err
5285 library and the compile_et program. (Addresses Debian bug #191900)
5287 Added the blkid_known_fstype() function to the blkid library, which
5288 returns true if it is passed a filesystem type which is recognized by
5289 the blkid probing functions.
5291 Improved the documentation for the blkid library.
5293 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
5294 returns the hardware sector size of a device, if it is available.
5296 Added a dependency in the blkid library's .so file to the uuid
5297 library, since the former uses the latter. (Addresses Debian bug
5300 Added --with-diet-libc and --disable-evms to the configure script.
5302 Fixed a minor memory leak in the badblocks program.
5304 Fixed a portability problem in tune2fs --- not all systems have strptime().
5306 Fixed a portability problem in debugfs with the use of getopt() more
5307 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
5310 Add support Windows support to ext2fs_get_device_size().
5312 Added (normally disabled) debugging code to the Unix I/O manager which
5313 causes it to disable all userspace caching if the NO_IO_CACHE is
5316 Changed the test I/O manager so it can always be linked into e2fsck,
5317 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
5318 configure script. The test I/O manager will only print any debugging
5319 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
5320 variables are set, which specifies which I/O operations are logged and
5321 a block number to watch, respectively. The log messages are sent to
5322 stderr by default, unless a filename is specified via the
5323 TEST_IO_LOGFILE environment variable.
5326 E2fsprogs 1.33 (April 21, 2003)
5327 ===============================
5329 Added a new utility program, logsave, which captures the output of a
5330 command in a log file, even if the containing directory hasn't been
5331 mounted yet (in which case the it saves the output in memory until it
5332 can write out the logfile). This is useful for capturing the
5333 output of fsck during the boot sequence.
5335 Fixed some portability problems that were causing problems under
5336 the Cygwin32 environment.
5338 Mke2fs now interprets a negative number to the -b option as a minimum
5341 Fixed a bug in mke2fs which was incorrectly checking the argument to
5342 the -g option if the default block size was used. (Addresses Debian
5345 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
5346 it can not find filesystem checkers for jfs, reseirfs, and xfs.
5348 E2fsck now updates the global free block and inode counters from the
5349 block group specific counters quietly. This is needed for an
5350 experimental patch which eliminates locking the entire filesystem when
5351 allocating blocks or inodes; if the filesystem is not unmounted
5352 cleanly, the global counts may not be accurate.
5354 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
5355 2.0 is not yet supported; this only pulled in the bug fixes: fixed
5356 possible hangs caused by bugs in calling waitpid, and not setting the
5357 pipe to non-blocking mode; also fixed a file descriptor leak; made
5358 sure all functions call log entry/exit functions.)
5360 Badblocks now flushes its output file as bad blocks are discovered.
5362 The uuid library is now more paranoid about assuming the correctness
5363 of the /dev/random device; it mixes in a stream of bytes from
5364 random/srandom, just in case.
5366 Update Debian files to reflect the fact that I am now the Debian
5367 maintainer of e2fsprogs. Other various Debian-specific packaging
5370 Move the source tarball generation functions from the top-level
5371 makefile to the util/gen-tarball script.
5373 Updated the Turkish .po translation file.
5375 Added Heimdal and MIT krb5 extensions to the com_err library to make
5376 it more compatible with com_err libraries from those distributions.
5378 Changed dumpe2fs to always display the superblock fields relating to
5379 the journalling and/or directory indexing feature even if those
5380 features are not enabled.
5382 Updated and clarify copyright statement vis-a-vis alpha releases of
5385 The ss library will now try to dynamically link to the readline
5386 library and use it if it is present in the system. This means that
5387 the debugfs program now has line editing and history features. The
5388 SS_READLINE_PATH environment variable is used to find a readline or
5389 readline-compatible library.
5391 E2fsck now finds most duplicate filenames (all when rebuilding all
5392 directories via the -D option) and offers to delete or rename
5393 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
5395 Fix bug in e2image. When writing out a raw image file, include data
5396 blocks from symlinks that do not store the symlink within the inode.
5398 Fix bug in resize2fs which incorrectly moved the block and inode
5399 bitmaps for sparse superblock filesystems and incorrectly marked
5400 blocks as in use. (Addresses Debian bug #174766)
5402 Added a new shared library, the blkid library, which efficiently
5403 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
5404 and UUID filesystem specifiers without needing to search all of the
5405 devices in the system. Instead, the device is looked up in a cache
5406 file, and then verified to make sure the blkid cache is correct.
5408 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
5409 the device name, using the blkid library. (Addresses Debian bugs
5412 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
5413 used for spaces in device labels.
5415 Removed 32-bit limitations for debugfs's dump command.
5417 If the user specifies a large number of inodes, Mke2fs will
5418 automatically adjust the number of blocks per group to find a valid
5419 set of filesystem parameters.
5421 Add workaround to detect broken MD devices where when some of the
5422 underlying devices are marked read-only, writes to the MD device are
5423 silently dropped. E2fsck will detect if there is an attempt to run
5424 the journal twice, and abort with an error if this is the case.
5425 (Addresses IBM Bugzilla bug #1226)
5427 E2fsck will print an error if more than one of the -p/-a, -n or -y
5428 options are specified.
5430 E2fsck will fix HTREE corruptions in preen mode, without stopping the
5431 boot process. This is needed because the 2.4 ext2 filesystem
5432 accidentally had the INDEX_FL backwards compatibility code removed.
5434 Mke2fs no longer creates filesystems with the dir_index flag set by
5435 default; the user has to specifically request it.
5437 Update and clarified various man pages. (Addresses Debian bugs
5438 #173612, #175233, #175113, and #170497, #185945, #188318)
5440 Created man page for the mk_cmds program (from the libss library).
5445 Fix various gcc -Wall nits.
5447 Fixed a lot of portability problems that caused e2fsprogs not to build
5448 successfully under Solaris and Apple/Darwin.
5450 Fixed a Makefile dependency to allow building e2fsprogs using parallel
5453 Changes to create a subset distribution which consists only of the
5454 et, ss, uuid, and blkid libraries. The configure script and top-level
5455 makefile were changed to support working with a subset distribution.
5457 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
5458 actually used, and might people who are looking for
5459 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
5461 Updated debian files to fix a number of Lintian warnings.
5463 Updated config.guess and config.sub with newer versions from the FSF.
5465 Removed unnecessary libraries from being linked into the fsck, lsattr,
5466 chattr, and blkid executables.
5468 E2fsprogs 1.32 (Nomvember 9, 2002)
5469 ==================================
5471 Fixed a bug in the Unix I/O routines which caused needless writebacks
5472 of clean blocks from the unix_io cache (they were erroneously marked
5473 as being dirty, so they were getting written back to disk before
5474 getting evicted from the disk cache). This was harmless, but it
5475 significantly slowed down e2fsck.
5477 Made some other minor optimizations to the Unix I/O routines to save a
5478 small amount of CPU time.
5480 Updated internationalization files.
5483 E2fsprogs 1.31 (Nomvember 8, 2002)
5484 ==================================
5486 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
5487 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
5488 handling for child process that die unexpectly. Add a hack to force
5489 mkfs to create filesystems that won't cause problems with hardware
5490 that has 2k or 4k minimum blocksize requirements. Read from child
5491 processes in non-blocking mode, so that the GUI continues to update.
5493 Fix e2fsck so that it returns the appropriate exit code when the root
5494 filesystem has been changed, so that system's rc scripts will be told that
5495 the system needs to be rebooted.
5497 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
5498 was set, some of the descriptor blocks that should have been written
5499 out were getting skipped.
5501 Changed e2fsck to force out changes to the backup copies of the
5502 superblock and block group descriptors when important changes are made
5503 to those data structures.
5505 Fix a bug where e2fsck could erroneously mark a filesystem as being
5506 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
5507 introduced in e2fsprogs 1.28.)
5509 If journal debuging is enabled using --enable-jbd-debug, the debugging
5510 level is now set via the E2FSCK_JBD_DEBUG environment variable.
5512 If byteswapping support is disabled using configure --disable-swapfs,
5513 skip the tests which depend on byte-swapping, so that "make check"
5516 Lshattr will now display the indexed directory flag. Also, some of
5517 the more esoteric compression flags are supressed unless compression
5518 support has been enabled.
5523 E2fsprogs 1.30 (October 31, 2002)
5524 =================================
5526 When resizing a filesystem, and inodes need to moved, resize2fs will
5527 update the inode's ctime field, and the mtime field of the containing
5528 directories, so that incremental backups using dump/restore will work
5531 In order to avoid spurious errors, e2fsck wil check the last
5532 superblock write time to determine whether or not it can safely use
5533 the LOW_DTIME checks to determine if there are inodes on the orphan
5534 inode linked list that had somehow gotten disconnected. (Addresses
5535 Sourceforge bug #620980)
5537 Partition in /proc/partitions that being with the string "lvm" are
5538 considered real partitions even if they do not end with a number.
5540 Fixed a bug in the the uuid generation function, where if /dev/urandom
5541 is not present, but /dev/random is, and there isn't sufficient
5542 entropy, the get_random_byte function could spin a loop forever.
5544 E2fsck, mke2fs, etc. will now reliably notice when image files are
5545 mounted using the loopback interface. (Addresses Sourceforge bug
5548 When flushing buffers (as is done by badblocks, for example) check to
5549 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
5550 FDFLUSH ioctl which causes the MD device driver which causes confusing
5551 syslog messages about obselete ioctl messages. (Addresses Sourceforge
5554 Debugfs's write command now checks to see if the destination filename
5555 exists before creating it. (Addresses Sourceforge bug #478195.)
5557 When installing man pages, search for compressed man pages using all
5558 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
5560 Fixed a bug in fsck where multiple filesystems specified on the
5561 command were not being checked in parallel due to a logic bug
5562 introduced to support the FSCK_MAX_INST environment variable.
5564 We have added a new superblock field, s_mkfs_time, which indicates
5565 when a filesystem was created. It is set via mke2fs, and printed out
5566 by dumpe2fs, but is not actually touched by the kernel.
5568 Dumpe2fs has been made more robust by not aborting if there is an
5569 error reading the block/inode bitmaps; instead it will still print out
5570 the location of the block/inode bitmaps and inode table.
5572 Add support for the an alternative block group descriptor layout which
5573 allows for on-line resizing without needing to prepare the filesystem
5574 in advance. (This is the incomat feature flag meta_bg.)
5576 Add support for storing default mount options in the superblock, so
5577 that the filesystem can be mounted with specific mount options without
5578 needing to specify them on the mount command line or in the /etc/fstab
5581 Add support for a new inode flag, which is to be used for indicating
5582 the top of directory hierarchies for the Orlov block allocator.
5584 Fix e2fsck so that if it creates the lost+found directory, it does so
5585 with the more apporpriate permissions of 0700. Also change
5586 mklost+found so that it also creates the directory 0700.
5588 Fixed format bug in e2fsck if NLS is in use.
5590 Add a German translation for e2fsprogs's NLS support.
5592 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
5593 the beginning of the inode table. This won't matter much, since if
5594 there is a bad block at the beginning of the inode table, the root
5595 directory won't be available. But at least e2fsck won't crash in this
5598 Fixed endian problems in the htree code for e2fsck and debugfs.
5600 When byte-swapping a filesystem on a PPC architecture, byte-swap the
5601 bitmaps since the historical big-endian ext2 variant had byte-swapped
5602 bitmaps, and the ext2fs library assumes this. This fixes the
5603 regression test suite on PPC machines.
5605 Fix e2image so that it handles a bad block in the inode table
5608 E2fsck now uses a more sophisticated algorithm to salvage corrupted
5609 directories that recovers more information in the corrupted directory
5612 E2fsck now performs additional consistency checks on indexed (HTREE)
5615 Fix bug where efsck might get confused about whether a completely
5616 empty directory block is an empty leaf block or an interior htree
5617 node. This could cause e2fsck to get confused into think that a valid
5618 indexed directory was corrupted.
5620 E2fsck no longer creates an empty directory entry at the end of a
5621 directory block when optimizing a directory. This would cause some
5622 earlier versions of the dxdir kernel code to corrupt the directory
5623 when attempting to split a node containing an empty directory entry.
5625 E2fsck could sometimes in rare circumstances leave the indexed flag
5626 set after a small directory was optimized by compressing it instead of
5627 indexing it. (This should never happen in real life, since
5628 directories that small wouldn't have been indexed, but better safe
5631 E2fsck now only updates the master superblock in all cases. This
5632 slightly shortens its run time.
5634 Ext2ed can deal with directory entries of length 0; previously it
5635 would get stuck in an infinite loop.
5637 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
5638 specifiers. (Sourceforge patch #613447)
5640 Badblocks will now work correctly on read-only devices such as
5641 CD-ROM's. (Sourceforge patch #600451)
5643 Updated and clarified man pages. (Addresses Debian bug #167108)
5646 E2fsprogs 1.29 (September 24, 2002)
5647 ===================================
5649 Fixed a bug in e2fsck which could corrupt a directory when optimizing
5650 it (via the -D option) or rebuiliding the hash tree index with a 1 in
5651 512 probability, due to a fence post error.
5653 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
5656 Mke2fs now enables the directory indexing flag by default. (Since
5657 this is a compatible feature flag, it's safe to do so.)
5659 Tune2fs will support setting the directory indexing feature flag. It
5660 will automatically set up the default hash algorithm and hash seed
5661 fields in the superblock.
5663 If the bone-headed user enters the root filesystem twice in
5664 /etc/fstab, the -R option which skips the root filesystem will skip
5665 all of them. (Addresses Debian bug #159423). Note! This is not a
5666 precedent for dealing intelligently with any other kind of doubled
5667 entry in /etc/fstab!
5673 Removed perror declaration in lib/et/internal.h. All modern systems
5674 can be expected to define perror() these days. Besides, the lib/et
5675 code wasn't using perror at all anyway. :-)
5678 E2fsprogs 1.28 (August 31, 2002)
5679 ================================
5681 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
5682 for setting the htree flag is not included yet, although it can be
5683 manually turned on via the debugfs program.
5685 Clarified e2fsck error message which is printed when it cannot find
5686 sufficient contiguous block when relcating filesystem metadata.
5688 Added support for building an EVMS plugin module for ext2/3. This
5689 module is substantially the same as the EVMS module shipping with EVMS
5690 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
5691 for use with EVMS 1.0 (which did not include the ext2 plugin module),
5692 if the configure --enable-old-evms flag is given.
5694 Fsck will search through EVMS volumes when trying to resolve
5695 filesystem specifications such as LABEL=xxx or UUID=xxx.
5697 Added a new utility program, /sbin/findfs, which will return
5698 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
5701 Update and clarified various man pages. (addresses Debian Bug #145044,
5702 #146437, #131350, #151990, #144621, #141938)
5704 If there are no filesystems specified on fsck's command line, fsck now
5705 treat that as if the -As options were given. Previously it would
5706 simply do nothing. (Addresses Debian Bug #153102)
5708 Mke2fs no longer treats a failure to be able to clear the MD signature
5709 at the end of the filesystem as a fatal error. (Addresses Debian Bug
5712 The e2p library functions (which are used by lsattr and chattr) now
5713 double check to make sure the file is a regular file or directory
5714 before attempting to use the ext2 ioctls. Some device drivers
5715 unfortunately respond to the ext2 ioctl's with unknown behaviour.
5716 (Addresses Debian Bug #152029).
5718 The extended attribute handling has been updated to correspond with
5719 the latest V2 bestbits ACL code.
5721 Fixed bug in e2fsck which caused it to not clear the dtime field when
5722 processing truncated inodes on the orphan list. This could cause data
5723 loss(!) if a filesystem is rebooted before a truncate has been
5726 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
5727 algorithms. This makes e2fsck much faster in the case of severely
5728 corrupted filesystems where a large number of blocks are claimed by a
5729 large number of inodes. (Thanks to the 2.5 IDE device driver for
5730 inspiring this work.)
5732 Resize2fs has been significantly sped up when shrinking and expanding
5733 a filesystem by a very small number of blocks (for example, when EVMS
5734 is converting a partition to be an EVMS legacy volume).
5736 Added a new option to e2fsck, -D, which will optimize or compress all
5737 of the directories in the filesystem.
5739 E2fsck now catches SIGINT and SIGTERM to make sure it will can
5740 properly clean up and only exit at safe points. Fsck will pass
5741 SIGINT/SIGTERM to its child processes, and wait until they have all
5742 exited before it exits.
5744 The uuid parsing code in the uuid library now properly complains when
5745 an illegally formated uuid is presented to it. (Addresses Debian bug
5748 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
5749 and 2.4.17, since the workaround can cause problems when using a 2.4
5750 kernel with an old version of glibc built with the 2.2 headers.
5752 Fixed a bug in mke2fs where it wasn't properly clearing the initial
5753 superblock used by other filesystems. (Addresses Debian bug #147256.)
5755 Added support for the synchronous directory feature written by Andrew
5758 The debugfs program can delete directories using the rmdir command.
5760 Add support for 8k and 16k filesystems (for systems with page sizes
5761 that are greater or equal to 8k or 16k, respectively). Note that
5762 these filesystems can not be mounted on x86 systems, or other systems
5763 with only 4k page sizes, due to limitations in the current Linux VM
5766 Resize2fs requires that the filesystem state be valid and have no
5767 errors; otherwise, e2fsck -f must be run first. (Previously it simply
5768 required that the last fsck time be greater than the last mount time.)
5770 Configure now defaults the man pages directory to /usr/share/man on
5773 E2fsck now offers to truncate inodes which contain too many blocks (so
5774 that i_blocks would overflow. Also fixed handling of large sparse
5777 E2fsck now more completely checks for symlink validity, including
5778 requiring NULL termination and length checks.
5780 E2fsck will offer to try forcing a disk write to remap a bad block
5781 after finding a read error when reading a filesystem metadata block.
5783 Fixed a bug in debugfs which caused the -b and -s options to crash
5784 debugfs, as well as breaking the testb, setb, and clearb functions.
5786 Added a bmap command to debugfs which calculates the logical to
5787 physical block mapping for a particular inode.
5789 Fixed a bug in code which checked to see if a device was mounted which
5790 sometimes (rarely) failed in the case of a plain file.
5792 Fixed a bug in resize2fs where when it reported an error, it would
5793 print a message erroneously indicating that the filesystem had been
5794 resized before it aborted.
5796 When resizing a plain file which is smaller than the requested size,
5797 resize2fs will attempt to extended the file so that programs like
5798 e2fsck will not complain that the file is too small.
5800 Resize2fs will print the actual new size of the filesystem when it is
5803 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
5804 information on big-endian systems.
5810 Fixed collisions with C++ reserved words.
5812 Added portability fixes for building e2fsprogs on the HURD and AIX.
5814 Added the ext2ed program for creation of test cases. (ext2ed has many
5815 limitations and bugs which make it unsuitable for production use.)
5817 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
5818 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
5819 name_len field is byte swampped on big-endian machines, since in the
5820 V2 structure, name_len is a char field which is doesn't need to be
5821 byte swapped --- except if an old-style kernel had byte-swapped the
5822 name_len field as part of the V1 structure.
5825 E2fsprogs 1.27 (March 8, 2002)
5826 ==============================
5828 The warning messages for mke2fs now go to standard error.
5830 Fixed to make sure "make check" runs all of the test programs with
5831 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
5833 The mke2fs program checks the boot sector for the BSD disk label, and
5834 avoids erasing it if it is there.
5836 Fixed a bug in e2fsck which caused it to core dump if the journal
5837 inode was missing when it was supposed to be there.
5839 E2fsck now prints ranges in pass 5 when printing deltas for the block
5842 Debugfs's "ls -l" command now will print out the file type information
5843 in the directory entry.
5845 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
5846 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
5848 Debugfs can now examine the experimental directory indexing
5851 Fixed bug in debugfs which caused it to core dump if modify_inode is
5852 called without an open filesystem.
5854 The debugfs lsdel command now runs its output through a pager first.
5856 When installing manual pages, remove the compressed manual pages first.
5858 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
5860 Fix the 2.4 resource limitation workaround introduced in 1.26 which
5861 actually broke things on mips32, sparc32, and Alpha platforms.
5863 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
5864 (which is required by the newer libintl libraries).
5869 Fixed various gcc -Wall complaints.
5871 Fixed a few memory leaks in the e2fsck journaling code, and in the
5872 ismounted code checking for a swap device.
5874 Add new inode I/O abstraction interface which exports an inode as
5877 Exported ext2_file_flush as a public interface.
5879 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
5881 Lots of small random portability fixes to make e2fsprogs build under
5882 AIX --- even without the 5L compatibility toolkit, and even using the
5883 uber-crippled AIX native C compiler.
5886 E2fsprogs 1.26 (February 3, 2002)
5887 =================================
5889 Dumpe2fs will keep going now if the bad block inode can't be read.
5890 (Previously it stopped with a fatal error.)
5892 E2fsck will now give an opportunity to run the journal even if the
5893 recovery flag is not set. This is the default behaviour if e2fsck is
5894 using a backup superblock, since the needs_recovery flag will never be
5895 set in the backup superblock copies.
5897 E2fsck now automatically finds the backup superblock/group descriptors
5898 even when the primary superblock is completely destroyed for 2k and 4k
5899 filesystems. (Previously it just guessed/assumed that we were dealing
5900 with a 1k filesystem in that case, and users had to manually specify
5901 the backup superblock number.)
5903 Fixed a bug in e2fsck where it dereferences a null pointer when there
5904 is a problem opening a filesystem in preen mode.
5906 E2fsck now handles external journals correctly; previously it trashed
5907 the external journal device if the journal needed to be replayed.
5909 Work around ulimit incompatibility problem caused by recent 2.4
5910 kernels; the unix IO module will automatically try to set any resource
5911 limits to be infinite on startup.
5913 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
5914 bitmap if it wasn't present and the blocksize was 2k or 4k.
5915 (Addresses Debian Bug #116975)
5917 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
5918 clearing the new V2 fields if they do not make sense or if the ext3
5919 superblock is version 1 superblock.
5921 E2fsck will automatically relocate the ext3 journal from a visible
5922 file (i.e., /.journal) to an hidden inode if the filesystem has been
5923 opened read/write. This allows the users to add a journal while the
5924 filesystem is mounted, but the next time the system is rebooted, the
5925 journal file will disappear. This avoids problems with backups,
5926 stupid operators with superuser bits, etc.
5928 Fix a bug in fsck where it would not support a filesystem type of
5929 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
5931 Fsck now supports fstab entries of the form "ext3,ext2". It will also
5932 automatically identify reiserfs filesystems.
5934 The number of processes spawned by fsck can now be limited using the
5935 FSCK_MAX_INST environment variable.
5937 Fsck now searchs the LVM proc hierarchy to find logical volumes which
5938 should be searched for UUID and label information.
5940 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
5941 limit if at all possible, when opening a block device. (The filesize
5942 limit shouldn't be applied against writes to a block device.)
5944 In mke2fs and e2fsck, specifying the -c option twice will now do
5945 a read/write test on the disk. Update the man pages to encourage
5946 using the -c option, and to discouraging running badblocks separately,
5947 since users tend to forget to set the blocksize when running
5950 Mke2fs now automatically clears the immutable attribute on a
5951 pre-existing .journal file left over from a previous failed attempt to
5952 add a journal to an alreadyy-mounted filesystem.
5954 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
5957 Mke2fs now creates the lost+found directory with permissions of 0700,
5958 so that files that had previously lived in protected directory are
5959 safe if they get dropped in lost+found and the system administrator
5960 doesn't deal with immediately. (Addresses Debian #bug 118443)
5962 Mke2fs and e2fsck (and all programs that use the
5963 ext2fs_check_if_mounted function) will now properly identify that a
5964 device is mounted, even in cases where devfs has confused things with
5965 multiple devices names with the same identity, or if a dim-witted
5966 system administrator has done something stupid like creating device
5967 file aliases in their home directory. Also now checks for swap devices
5968 by using /proc/swaps. (Addresses Debian bug #106622)
5970 Added a new option (-T) to tune2fs which sets the time a filesystem
5973 Speed up e2image when creating sparse raw image files by optimizing
5974 away excess lseek() system calls.
5976 Fix support of large (> 2GB) files when used as a filesystem in
5977 mke2fs, tune2fs, debugfs, and findsuper.
5979 Debugfs's stat and icheck commands now properly deals with large (>
5982 Debugfs's set_super_value command now prints out the list of valid
5983 superblock fields which can be set using the command.
5985 Debugfs's rm and kill_file command now updates the superblock free block
5986 and inode counts, thus keeping the filesystem consistent.
5988 Debugfs's lsdel command now takes an optional argument which allows
5989 the user to only see the most recently deleted files.
5991 A new command (undel) was added to debugfs which automates
5992 undeleting a deleted inode and linking it back to a directory.
5994 Debugfs's ls command now takes a new option, -d, which lists
5995 deleted directory entries.
5997 Debugfs's testb, freeb, setb, and find_free_block commands now take an
5998 optional count argument.
6000 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
6001 be used to signal that a particular inode should not be eligible for
6002 tail-merging --- this is needed for programs like LILO.
6004 The findsuper (an unreleased, uninstalled utility program) has been
6005 improved to add extra validity checks and to add a progress meter.
6006 (It is still an unsupported program; the officially supported way to
6007 recover from a trashed partition table is to use gpart; findsuper is
6008 for wizards only. :-)
6010 Debugfs was fixed to compile with "configure --disable-swapfs".
6012 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
6014 Added new translation file for Turkish.
6019 Fix general gcc -Wall complaints.
6021 E2fsprogs (mostly) works with the dietlibc.
6023 The programming texinfo file has been expanded to include description
6024 of additional libext2fs functions. (Still not compeltely done, but a
6025 lot of the more important functions have been documented.)
6027 Added a umask structure to struct_ext2_filsys, which currently only
6028 modifies the behaviour of ext2fs_mkdir(), but if we add any file
6029 creation functions to libext2fs, we should also make sure they respect
6032 The build-rpm script was fixed to be a bit more safe.
6034 The tests' Makefile now has a way of automating test case creation
6035 for e2fsck, using "make testnew".
6037 Created a new function, ext2fs_dir_iterate2 which passes more
6038 information to the callback function (identical to the one used by
6039 ext2fs_dblist_dir_iterate). The directory iterator functions take a
6040 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
6041 directory entries. If the directory entry is deleted, the callback
6042 function will be called with the entry paraemter set to
6043 DIRENT_DELETED_FILE.
6045 Added new functions, ext2fs_inode_alloc_stats and
6046 ext2fs_block_alloc_stats, which takes updates block/inode allocation
6047 statistics in the bitmaps, block group descriptors, and superblock
6048 when inodes or blocks are allocated or deallocated.
6051 E2fsprogs 1.25 (September 20, 2001)
6052 ===================================
6054 This is primarily a bug-fix release; no new features were added, but
6055 there are a number of embarassing bug fixes and cleanups applied.
6057 Fix a bug mke2fs which causes stack garbage to be written to disk when
6058 zapping disk sectors. (This bug could cause mke2fs to core dump for
6059 some kernels, I suspect with security enhancement patches.)
6061 Remove unneeded #include of <linux/config.h> which was breaking
6062 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
6064 Updated tune2fs man page to reflect the fact that adding or removing a
6065 journal doesn't require running e2fsck.
6067 Remove use of AC_REQUIRE from autoconf which had been used to prevent
6068 AC_CANONICAL_HOST from being called twice; unfortunately this causes
6069 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
6070 used outside of autoconf macros. Fortunately, it doesn't seem to be
6071 necessary any more, anyway.
6073 E2fsck will now not fall back to an alternate superblock if the user
6074 specifies the superblock location explicitly on the command-line.
6075 This allows easier recovery from a situation where the primary
6076 superblock and block groups are slightly corrupted, but the backup
6077 superblocks are completely broken.
6079 Fix problem which caused compile_et and mk_cmds to blow up if
6080 e2fsprogs was in a directory with a pathname that contained spaces.
6082 We are now more paranoid about checking the entry in /etc/mtab to make
6083 sure the filesystem is really mounted, since some broken distributions
6084 (read: Slackware) don't initialize /etc/mtab before checking non-root
6085 filesystems. (Slackware also doesn't check the root filesystem
6086 separately, and reboot if the root filesystem had changes applied to
6087 it, which is dangerous and broken, but there's nothing I can do about
6090 Make UUID library C++ friendly by adding appropriate extern "C"
6091 declarations and using const in the function declarations.
6093 Fix up the com_err texinfo file so that it can product a valid info
6094 file (previously, it could only be used to generate paper
6095 documentation using texinfo.tex).
6098 E2fsprogs 1.24a (September 2, 2001)
6099 ===================================
6101 Fix brown-paper bug in mke2fs which caused it to segfault when
6102 printing the version string.
6105 E2fsprogs 1.24 (August 30, 2001)
6106 ================================
6108 Revert the BLKGETSIZE64 support, since for some distributions, this
6109 ioctl has been used by an unofficial kernel patch to update the last
6110 sector on the disk, and this was causing disk corruption problems as a
6113 Mke2fs is now more careful about zapping swap space signatures and
6114 other filesystem/raid superblock magic values so that programs like
6115 mount who try to use hueristics to determine the filesystem type of a
6116 partition are less likely to be confused.
6118 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
6119 regular file (since Andreas Dilger's on-line resizing tools will set
6122 Fixed some minor texinfo, man pages nits for spelling errors,
6123 texinfo warnings, etc. (Addresses Debian bug #110621.)
6125 E2fsprogs program no longer print the filesystem version number
6126 (i.e. 0.5b), since it only confuses people and doesn't serve any real
6129 E2fsck will once again compile under libc5, since it will supply its
6130 own version of strnlen if necesssary.
6132 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
6133 when specifying the external journal device. tune2fs will also search
6134 devices looking for the externla journal debice when removing.
6136 E2fsprogs 1.23 (August 15, 2001)
6137 ================================
6139 Add initial support for extended attributes (EA); e2fsck will
6140 correctly handle a filesystem with EA's and check the EA blocks for
6143 E2fsck's symlink sanity checking has been cleaned up. It now checks
6144 the i_size value of fast symlinks, and checks for immutable flags
6145 being set of symlinks, etc.
6147 E2fsck now offers to clear inodes which are special files that have a
6148 non-zero i_blocks or i_size field. (The i_size field check was in the
6149 previous version of the code, but due to a bug it didn't offer to
6150 clear the inode unless i_size and i_size_high were both non-zero.)
6152 E2image can now create "raw" image files, which only contain the
6153 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
6154 debugfs, etc., can be run directly on the raw image file.
6156 Add support for the 64-bit block device patches.
6158 Fixed bugs in creating external journals with a 1k blocksize.
6160 Add initial support for external journals (so long as the external
6161 journal only supports a single filesystem) in e2fsck.
6163 Remove requirement for needing to run fsck on a filesystem after
6164 removing a journal (either internal or external).
6166 The man pages now document how to create and manage external journals.
6168 Speed up the check of an ext3 filesystems by avoiding a needless flush
6169 of all of the superblock and block group descriptors.
6171 Speed up creating an internal journal using tune2fs in the case where
6172 the filesystem has a lot blocks already allocated.
6174 Tune2fs has been fixed to make sure that only error messages go to
6175 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
6177 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
6178 now not set the sparse_super feature. (Addresses Debian bug #108165)
6180 Add support in fsck for the filesystem type "auto".
6182 Fsck -A will not try to interpret device names for filesystems which
6183 have a pass number is 0. (Addresses Debian bug #106696).
6185 Fsck prints a warning message if now valid filesystems are passed to
6186 it. (Addresses Debian Bug #107458.)
6188 E2fsck now gives an explicit warning if there filesystem still has
6189 errors at the end of the run. (Addresses Debian bug #104502)
6191 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
6192 reflects an error. E2fsck will also not run the orphan list if the
6193 filesystem contains errors, since the orphan list might be corrupted.
6195 E2fsck now prints the number of large files when given the -v option.
6197 Fixed minor memory leaks in e2fsck.
6199 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
6202 E2fsprogs 1.22 (June 22, 2001)
6203 ==============================
6205 Fixed a bug in e2fsck's handling of orphan inodes which are special
6206 files (i.e., block/character device files, named FIFO's, etc.).
6208 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
6209 tune2fs to fail at adding a journal to a mounted filesystem.
6211 Fixed a few big-endian bugs in e2fsprogs
6212 * The directory block functions were accidentally reporting
6213 some directories as corrupted when they weren't.
6214 * If e2fsprogs is compiled --disable-swapfs, the C language
6215 equivalents weren't being included for big-endian platforms.
6216 (Fixes Debian bug #101686).
6218 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
6223 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
6224 ioctls, and allow them to be defined for non-i386 platforms.
6226 The uuid.h header file is now protected against multiple inclusions.
6228 E2fsprogs is now being developed using BitKeeper. Changed the test
6229 scripts to deal with BK's stripping CR characgters from text files,
6230 and changed the top-level Makefile.in to avoid including BitKeeper
6231 files when generating the source tarball.
6234 E2fsprogs 1.21 (June 15, 2001)
6235 ==============================
6237 Added new configure flags which allow a subset e2fsprogs to be built;
6238 this is most useful for boot floopies, since the resulting shared
6239 libraries and programs are slimmed down by removing features that
6240 aren't necessary for a boot floppy. The new flags that were added
6241 are: --disable-swapfs, which removes support for byte swapping old
6242 legacy PPC/68k filesystems, --disable-debugfs, which removes support
6243 for debugfs from the libext2fs library, --disable-imager, which
6244 removes support for the e2image program, and --disable-resizer, which
6245 removes support for resize2fs.
6247 E2fsck now prints the number of mounts or days elapsed since the last
6248 check when e2fsck is forced to check an otherwise clean filesystem.
6250 Tune2fs now prints an informative message about how often a filesystem
6251 will be checked when adding a journal to the filesystem, to remind the
6252 user that he/she may want to adjust those parameters using tune2fs
6255 Worked around hurd brain-damage which causes e2fsck to sometimes
6256 believe a filesystem is the root filesystem based on device numbers
6257 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
6260 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
6261 erroneous error with the -F option was specified.
6263 Fixed a ext3 recovery bug in the revoke handling; synchronized with
6266 Fixed two bugs in e2fsck's handling of dup block handling, dealing
6267 with relatively uncommon edge cases: a directory with an indirect
6268 block which is claimed by another file, and when the last inode in the
6269 filesystem has blocks claimed by another file.
6271 E2fsck now checks to see if the i_size field of a fast symlink is too
6272 big, and offers to clear the symlink if so.
6274 E2fsck now checks to see if i_size_high of special files is non-zero,
6275 and offers to clear i_size_high.
6277 Fix e2fsck's handling of incompatible journal flags so that the user
6278 has chance to abort, and then has the option to clear out the journal
6279 entirely. (Addresses Debian bug #98527.)
6281 Fixed a bug in fsck which could cause it to core dump if a mix of
6282 standard and non-standard device names are used in /etc/fstab.
6283 (Debian bug #100559)
6285 Fixed a bug in debugfs which caused read errors when copying a file to
6288 The debugfs set_super_value command can now modify the s_lastcheck field.
6290 Fixed a bug in lsattr and chattr which was accidentally introduced in
6291 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
6292 directories correctly because the change modified the layout of struct
6293 dirent to be incompatible with the libe2p shared library.
6295 Cleaned up the mke2fs manual page and included a discussion about why
6296 it's good to periodically check the filesystem even when journaling is
6302 Fix general gcc -Wall complaints.
6304 The types needed by the ext2 header files are now provided by
6305 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
6307 Integers are now preferred to longs when trying to find a 32-bit type
6308 in ext2_types.h. Also, if linux/types.h has already been defined,
6309 don't try to redefine the types.
6311 Fixed make depend script so that it automatically corrects the
6312 pathname cleanups performed by make -M, so I don't have to fix them up
6315 Fixed the d_loaddump test case to be more robust, and not depend on
6318 Removed debugfs's dependence on pread(), which was accidentally
6319 intrudced in e2fsprogs 1.20
6321 Fixed a performance bug in the libext2fs's icount routine; the size
6322 estimate of the icount array was incorrectly being calculated.
6324 Removed use of the badblocks compatibility functions in the e2fsprogs
6327 Added paranoia code which protects against strange cases where /etc
6328 isn't on the root filesystem, or if /etc/mtab doesn't exist.
6330 The header file ext2_types.h is now installed.
6332 Autoconf is used to determine when we are on big-endian machines,
6333 instead of doing run-time tests, to save a few bytes of code.
6335 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
6336 functions are no longer inline functions, which saves space and
6337 doesn't really cost any real performance.
6339 The ext2fs library no longer depends on the e2p library. (What need
6340 there was of it --- namely, fsetflags, was coded in-line).
6342 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
6343 when the user is stupid and tries compiling the package using "make
6346 Miscellaneous code cleanups:
6347 * Added missing files from Makefile.in's SRCS file, so that
6348 their dependencies would be properly calculated.
6349 * Removed redundant code
6350 * Fixed comments in code
6351 * Removed no-longer unneeded argsused #pragma.
6354 E2fsprogs 1.20 (May 20, 2001)
6355 =============================
6357 Add support for replaying the ext3 journal purely in user mode,
6358 including handling the orphaned inode list. Used code contributed by
6359 Andreas Dilger, with bug fixes and the orphaned inode handling done
6362 The mke2fs and tune2fs programs can create or modify a filesystem to
6363 include an ext3 journal. Tune2fs also can be used to remove an ext3
6364 journal from a filesystem.
6366 E2fsck will now check for the existence of a linked list of orphan
6367 inodes in the superblock, and clear those inodes before starting the
6368 rest of the filesystem check (but after the journal playback).
6370 E2fsck now validates the file descriptor passed to the -C option,
6371 which saves against the completion bar getting written to an
6372 unexpected location, such as the disk being checked. (Debian
6373 bug/wishlist #55220)
6375 E2fsck will now bump the filesystem revision number from zero to one
6376 if any of the compatibility bits are set.
6378 Fixed a bug where a badly corrupted directory on a big endian system
6379 could cause e2fsck to die with a bus error. The
6380 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
6381 the ext2 library now does alignment sanity checks on the rec_len field
6382 of the directory entry before using it.
6384 The ext2 library has been enhanced to make tune2fs safe to run on
6385 mounted filesystems. (Users could usually get away with using tune2fs
6386 on mounted filesystems before, but with the advent of ext3 and
6387 journaling, it became important to make tune2fs was *really* safe for
6388 use even when the filesystem being modified is mounted.) E2label is
6389 now implemented by tune2fs using an argv[0] dispatch, so that e2label
6390 is also now safe for use on mounted filesystems.
6392 Added a new program, e2image, which creates a backup of critical ext2
6393 filesystem data structures. The generated image file can be examined
6394 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
6395 the image file to help recover very badly damaged filesystems.
6397 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
6398 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
6399 large file when deciding whether or not the filesystem has large files.
6401 Fixed lsattr and chattr so that they work correctly on large files.
6402 (Fixes Debian bug #72690.)
6404 Removed limitation in get_device_size() which imposed a one terrabyte
6405 filesystem limitation. (Most 2.2 kernels still have a signed int
6406 problem which cause 1 TB block device limitation. Fortunately, the
6407 kernel patches to fix this are much easier than fixing the 2TB
6408 limitation in the kernel. :-)
6410 A max_mount_count of zero is now treated as if no mount count were
6411 set. (Previously, no mount count was indicated by using -1, and a
6412 mount count of zero caused e2fsck to always be run.)
6414 Mke2fs supports two new filesystem types largefile and largefile4.
6416 Mke2fs now adds some randomness in s_max_mount_count so that multiple
6417 filesystems won't be all checked at the same time under normal
6420 Fixed bug in the progress bar printing code which could cause e2fsck
6421 to core dump on an illegal filesystem.
6423 Fixed bug in fsck which could allow more than one instance of e2fsck
6424 to be printing a progress bar. (Debian bug #65267)
6426 Fsck using a UUID or a LABEL specifier will work even if devfs is
6427 compiled into the kernel and not mounted. If the pathnames in
6428 /proc/partitions are incorrect, fsck will search /dev for the correct
6429 device (using the new ext2fs_find_block_device library function).
6430 Fsck now also checks the RAID devices first so that they are properly
6431 found when they are in use. Support has also been added to support
6432 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
6434 Fixed a bug in fsck which caused it not deal properly with 16
6435 byte long filesystem labels.
6437 Fsck's -t option has been made a lot more flexible. The semantics for
6438 what happens if a comma-separated list to fsck has been regularized,
6439 and it is now possible to filter what filesystems will get checked
6440 based what is in the filesystem's fstab entry's option field. (Debian
6443 The dumpe2fs program can now print out the group description
6444 information in hex, and also prints the location of the superblock and
6445 block group descriptor for those block groups that have them.
6447 Mke2fs now clears the ext2 superblock before it starts creating a
6448 filesystem, so that the superblock magic number is only written if the
6449 filesystem creation process successfully completes.
6451 The debugfs program's stat command now pretty-prints the blocks used
6452 by an inode so that it's more compact and informative.
6454 The debugfs stats command now uses the same libe2p code (which is used
6455 by dumpe2fs) to print the superblock header information. This is more
6456 complete, and it avoids a bit of code duplication.
6458 Added a new debugfs command, set_super_value (ssv) which allows the
6459 user to set arbitrary superblock fields.
6461 Debugfs was extended to support inode numbers in hex (by prefixing
6462 them with 0x), and so that modify_inode can set the inode generation
6463 number. Also, there is now a new function command called logdump
6464 which will dump an ext3 journal.
6466 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
6469 Debugfs's dump command now stops immediately upon reporting a disk
6470 read error. (Fixed a bug in ext2fs_file_read library routine which
6471 caused debugfs not to stop.) (Debian bug #79163)
6473 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
6474 checked before /etc/mtab is used, since /proc/mounts is more likely to
6477 Added portability fixes for Solaris and Linux/ia64.
6479 Various manual pages were clarified and cleaned up. (Fixed debian
6480 bugs #63442, #67446, and #87216)
6486 The e2fsck message printer now supports %Iu and %Ig, which will print
6487 out the inode's user and group owners, respectively.
6489 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
6490 that no longer dependent on the system having the correct version of
6491 the kernel header files.
6493 Added a new function to libext2, ext2fs_find_block_device(), which
6494 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
6495 device given its device number.
6497 Added a new function to libext2, ext2fs_sync_device, which centralizes
6498 all of the places which might try to use the BLKFLSBUF or FDFLUSH
6499 ioctls (and usually failing to define them since the system header
6500 files don't usually do this for us, and we're trying to avoid usage of
6501 kernel include files now).
6503 Added new utility programs in tests/progs: random_exercise and
6504 hold_inode. They aren't built by default; they're useful for
6505 exercising ext3 filesystem code.
6507 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
6508 the filesystem close functions to only update the superblock, and to
6509 not touch the block group descriptors. Needed by tune2fs when
6510 modifying a mounted filesystem.
6512 Got rid of struct ext2fs_sb and replaced it with the standard struct
6513 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
6514 source (but not binary) compatibility of some users of the ext2
6515 library. Those applications should just simply do a global search and
6516 replace of struct ext2fs_sb with struct ext2_super_block, and include
6517 the new header file <ext2fs/ext2_fs.h> which defines it.
6519 The ino_t type has been renamed ext2_ino_t to protect applications
6520 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
6521 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
6522 unexpected ABI change.
6524 The Makefiles have been reworked so that "make check" can be run from
6525 the top-level Makefile.
6527 Fix general gcc -Wall complaints and removed dead code.
6529 Remove use of NOARGS, because we assume everyone does ANSI C these
6532 Added build-rpm script from sct.
6534 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
6537 New function ext2fs_flush_icache which must be called if the
6538 application program modifies the inode table blocks without going
6539 through ext2fs_write_inode() interface.
6541 New ext2fs_check_mount_point() function, which will return the mount
6542 point of a device if mounted.
6544 The io_channel abstraction now has an optional interface,
6545 io_channel_write_range, which allows specific byte ranges to be
6548 The unix_io IO channel now supports write-through caching, so that
6549 journal creation is more efficient.
6551 Added x86 assembly language routines to support byte swapping, to
6552 reduce executable size.
6554 Fixed bug in the utility program subst so that it's possible to
6555 replace a substitution variable with a zero-length string.
6557 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
6558 slipped into some of the problem number.
6560 E2fsprogs 1.19 (July 13, 2000)
6561 ==============================
6563 Release the resize2fs program since the timeout before it could
6564 be released under the GPL has finally expired.
6566 Add experimental support needed for the ext2 compression patches.
6567 This requires compiling e2fsprogs with the --enable-compression flag
6568 to the configure script.
6570 Added ext3 journalling support. E2fsck will run the journal (if
6571 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
6572 installed as a symlink to e2fsck. Fsck has been taught about ext3,
6573 and treats it the same as ext2 in terms of the progress bar logic.
6574 Dumpe2fs will display the superblock journaling information if the
6575 filesystem has a journal. The ext2 library will now permit opening an
6576 ext3 filesystem with the recovery flag set. This is necessary for
6577 on-line dump's to work correctly, but there may be issues with this
6578 working well since ext3 is much less agressive about syncing blocks to
6579 the filesystem, since they're safe on the journal.
6581 Tune2fs and e2fsck have been changed to allow the mount_count check to
6582 be disabled by setting max_mount_count to -1. (This was already
6583 supported by the kernel.)
6585 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
6586 are used for ext3 as well.
6588 Added internationalization support for e2fsprogs; must be enabled
6589 by passing --enable-nls to configure.
6591 Always use the provided ext2fs header files to insulate ourselves from
6592 kernel version changes. Which include files are used by e2fsprogs
6593 have also been cleaned up to improve portability.
6595 Limit the number of times that e2fsck updates the progress bar so that
6596 people who are booting using a 9600 baud console don't get swampped by
6599 Improved the loop detection algorithm in e2sck's pass #3 so that it is
6600 much, much faster for large filesystems with a large number of
6603 The memory footprint for e2fsck is now slightly smaller than before.
6605 E2fsck now checks if special devices have a non-zero size, and offers
6606 to clear the size field if it finds such an inode.
6608 E2fsck now checks if special devices have the append-only flag set,
6609 and offers to clear the inode.
6611 E2fsck now properly handles some "should never fail" cases during a
6612 bitmap copy in pass5.
6614 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
6616 E2fsck now calculates the correct location of the backup superblock in
6617 the case of filesystem blocksizes > 1k.
6619 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
6620 which normally didn't cause problems under most filesystem parameters,
6621 but could cause a valid superblock to be rejected in extreme cases.
6622 Other checks for validating superblock values were made more
6625 Added non-destructive write testing to the badblocks program, courtesy
6626 of David Beattie. The badblocks also now has an option to input the
6627 current set of bad blocks, so that known bad blocks are skipped to
6628 speed up the badblocks test. There is also a persistent rescan
6629 feature which causes badblocks to run until it has completed some
6630 number of passes without discovering any new bad blocks.
6632 Badblocks now checks to see if the device is mounted and refuses to do
6633 the tests involving writing to the device if it is mounted. Also,
6634 badblocks now allows the number of blocks to be checked to be
6635 defaulted to the size of the partition.
6637 Fixed a bug in fsck which didn't allow non-root users to be able to
6638 check filesystems if there were any LABEL= or UUID= entries in
6641 The Hurd doesn't support the filetype filesystem feature. The mke2fs
6642 program now makes sure that for the Hurd, the filestype feature is
6643 turned off. E2fsck will check to see if the filetype feature is
6644 turned on for Hurd filesystems, and offer to turn off the feature.
6646 Mke2fs now has a safety check to make sure the number of blocks do not
6647 exceed 32 bits even on a 64 bit platform.
6649 Really fixed a bug in fsck to allow "fsck -As" to run interactive
6650 fsck's. (For those people who like to do interactive fsck's in the
6653 Debugfs has a few new features: the rdump command, which will do a
6654 recursive dump of a directory and all of its contents, and the lcd
6655 command which does a local chdir (much like the ftp command of the
6656 same name). In addition, the debugfs program and the open_filesystem
6657 command now takes three new options: -b and -s, which allows the
6658 blocksize and superblock location to be specified, and the -c option
6659 which is used in catastrophic situations where the block group
6660 descriptors are corrupt. If the -c option is specified, debugfs will
6661 skip trying to read in the block and inode bitmaps.
6663 Debufs's lsdel command was fixed to handle bad blocks in the inode
6666 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
6669 General improvements in error messages
6671 - Mke2fs prints a sane error message if the partition size is zero
6672 (usually because the partition table wasn't reread by the
6673 kernel due to the partition being busy), instead of "invalid
6674 argument passed to ext2 library while initializing superblock".
6676 - Fsck now prints more self-explanatory message if an invalid UUID=
6677 or LABEL= specification is passed to it.
6679 UUID library changed to use the LGPL.
6681 Fixed a bug in the UUID library where very rapid calls to the
6682 time-based UUID generator could cause duplicate UUID's to be returned.
6683 This was not a problem for e2fsprogs, but it could be a problem for
6684 other users of the library.
6686 Make the UUID library more robust in the face of missing or an
6687 improper /dev/urandom or /dev/random files.
6689 Added some random portability fixes for Solaris.
6691 Some minor man page updates.
6693 Fixed a memory leak in the ss library.
6699 We now try to use lseek64 and open64 from the LFS if possible.
6701 The 3rd parameter in e2p's print_flags is now a flags word, instead of
6704 The mark and unmark bitmap functions now return the previous state of
6705 the bit that was being changed, which is useful for some speed
6708 The following functions have been added to enhance the badblocks list
6709 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
6710 ext2fs_badblocks_equal.
6712 The ext2 header files now have the latest journalling fields to the
6715 The ext2fs_mkdir function in libext2fs now properly backs out of error
6716 conditions robustly.
6718 Cleaned up makefiles:
6719 - to cleanly compile with the -j flag.
6720 - so distclean removes all generated files.
6721 - so in case of an error while installing header files, the make aborts.
6723 Fix test_script so that it works correctly when compiling in the
6726 The random UUID generation routine has been made slightly better in
6727 the case where /dev/random doesn't exist. (Use of randomly-based UUID
6728 is still not recommended if /dev/random doesn't exist, however; it's
6729 better to use the time/ethernet MAC address UUID in this case.)
6731 Clean up the build process so it's more friendly in case of missing
6734 The ext2fs header file can now be #include'd into C++ programs.
6736 The e2p.h header file is now installed.
6738 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
6742 E2fsprogs 1.18 (November 10, 1999)
6743 ==================================
6745 Fix a core dumping bug in e2fsck if an imagic inode is present or
6746 (more rarely) if the filesystem is badly corrupted enough that e2fsck
6747 has to restart pass 1 processing. E2fsck now closes the filesystem
6748 before freeing a large number of its data structures, so in the case
6749 of future memory faults, at least the fixed filesystem will be fully
6752 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
6753 imagic inode, it will offer to clear the imagic flag.
6755 E2fsck will now offer to clear the immutable flag on special files
6756 (device/socket/fifos) when running it in non-preen mode.
6758 E2fsck will now set the filetype when creating /lost+found, and when
6759 connected orphaned inodes to /lost+found.
6761 Debugfs's ncheck and icheck commands now handles the case where there
6762 are bad blocks in the inode table without bombing out.
6764 The badblocks list processing code has been made more efficiently for
6765 appending a large number of (ordered) badblocks to the badblocks list.
6767 Some minor man page updates.
6769 Fsck now allows interactive e2fsck's when using fsck -As (not a common
6770 mode, but some people like to do this in boot scripts for silly reasons).
6775 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
6776 with the problem code convention.
6778 The badblocks list regression test program has been updated to work
6779 with previously made API name changes.
6781 The ext2fs_free() command now uses the new badblocks API to avoid
6782 using the compatibility layer.
6784 Added new regression test cases; the run_e2fsck test script now
6785 supports the ability for a test case to run a prepratory command
6786 before running e2fsck.
6788 E2fsprogs 1.17 (October 26, 1999)
6789 =================================
6791 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
6794 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
6795 thus potentially causing problems if a binary UUID contained a NULL
6798 E2fsck now uses stricter checks for directory entries in pass 2:
6799 zero-length filenames are not allowed; neither are 8 byte long
6802 The debugfs "dirty" command now clears the filesystem valid bit.
6803 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
6804 bit in the in-core superblock image. The new functionality is more
6805 what the user expects, and is more useful.)
6807 Added a debugging hook to test parallel fsck; if the environment
6808 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
6809 will be checked in parallel when they normally would not be.
6814 Fixed some #ifdef's for compilation under the Hurd OS.
6816 Fixed minor W2K compatibility problems.
6818 Fixed some miscellaneous GCC warnings.
6821 E2fsprogs 1.16 (October 22, 1999)
6822 =================================
6824 Fixed a race condition bug in fsck; when printing a progress bar, if
6825 checking multiple filesystems in parallel, it was possible for fsck to
6826 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
6827 handler, which would cause it to terminate with a signal 10.
6829 E2fsck now properly handles filesystems that have the
6830 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
6831 filesystem into using or not using FILETYPE feature.
6833 E2fsck now properly handles filesystems that have the IMAGIC feature
6834 turned on (this is used on Linux AFS servers).
6836 The mke2fs program now creates filesystems that have the filetype and
6837 sparse_superblock features enabled by default, unless it is run on a
6838 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
6839 so there is now a new flag -O which allows the user to specify with
6840 which features she would like to create the filesystem; "mke2fs -O
6841 none" will create a filesystsem compatible with 2.0 kernels.
6843 The tune2fs program now has a -O option which allows the user to set
6844 and reset "safe" filesystem features. Currently, the only ones which
6845 allows to be modified are the filetype and sparse_superblock features.
6846 Note setting or clearing either feature will require running e2fsck on
6847 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
6848 requires that there is enough free space on the filesystem for the
6849 extra superblocks which will be created by e2fsck.)
6851 Debugfs can now set and print filesystem features in the superblock
6852 using the "features" command. Dumpe2fs will print out the complete
6853 set of features when listing the superblock.
6855 Dumpe2fs has new options -f (force) and -h (header-only).
6857 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
6858 message to come up. This could happen when decrementing or
6859 incrementing a link count could result in an overflow.
6861 Fixed a bug in e2fsck where the block count on the lost+found
6862 directory would not be properly incremented when the directory was
6863 expanded to the point where an indirect block needed to be allocated.
6865 E2fsck now makes some additional sanity checks on the superblock to
6866 avoid crashing or giving a memory allocation error if some of the
6867 values in the superblock are unresonable (but the superblock otherwise
6870 Fixed a bug in e2fsck where a very badly corrupted filesystem might
6871 require two passes to completely fix the filesystem. This happened if
6872 an inode claimed blocks that was part of the filesystem metadata
6873 (typically, when garbage was written into an inode table or indirect
6874 block, since this kind of filesystem corruption normally doesn't
6877 On the Alpha, glibc declares st_flags although it isn't actually used;
6878 the configure script was improved to detect this case so that
6879 e2fsprogs can avoid using the non-functional stat field.
6881 The manual pages were updated to use a more consistent formatting
6882 style consistent with standard Unix man pages. Mke2fs's man page
6883 added documentation for a few previously undocumented options.
6885 Fixed minor display bugs in tune2fs and mke2fs.
6890 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
6892 Added features to parse and print feature strings into the e2p library.
6893 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
6895 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
6896 whose directory entries contain proper filetype information if the
6897 filesystem supports it.
6899 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
6900 the directory entry filetype information. This is used to set the
6901 directory entry filetype information if the filesystem supports it.
6903 Fixed a bug in ext2fs_expand_dir() where the block count in a
6904 directory's inode would not be properly incremented when the directory
6905 was expanded to the point where an indirect block needed to be
6909 E2fsprogs 1.15 (July 18, 1999)
6910 ==============================
6912 Add configuration checks so that e2fsprogs will compile cleanly on
6913 Linux 2.3 kernels that have renamed i_version to i_generation.
6915 E2fsck now prints a progress/completion bar (and not just a simple
6916 spinner) if the -C0 option is requested or if it receives a SIGUSR1
6917 signal. Fsck will automatically manage the (potentially muliple)
6918 e2fsck processes to print completion bars if it is given a -C option,
6919 with the right thing happening if multiple filesystems are being
6920 checked in parallel.
6922 Mke2fs now has better automatic hueristics to determine the filesystem
6923 parameters to be used for a particular filesystem. Added a new option
6924 -T which allows the user to specify how the filesystem is to be used,
6925 which helps mke2fs do a better job selecting the filesystem parameters.
6927 Mke2fs now creates revision 1 filesystems by default, and with the
6928 sparse superblock feature enabled. The sparse superblock feature is
6929 not understood by Linux 2.0 kernels, so they will only allow read-only
6930 mounts of filesystems with this sparse superblocks.
6932 Fix bug where if /dev/null couldn't be opened (should never happen),
6933 e2fsck would hang in a tight loop.
6935 Make e2fsck handle the case where /lost+found isn't a directory.
6937 E2fsck now uses mallinfo if it exists to get accurate statistics about
6940 Fix bug in e2fsck where it wouldn't check to see if a disconnected
6941 inode had any problems before connecting it to /lost+found.
6943 Add check to e2fsck so it makes sure that total number of inodes in
6944 the filesystem is a sane number.
6946 Fix fencepost error when clearing an the end of the block bitmap which
6947 caused the last block in the bitmap not to get cleared.
6949 Cleaned up a number of messages in e2fsck:
6950 * The message "Group's #'s copy of the group descriptor..."
6951 was fixed so that the correct number would be displayed.
6952 * Added missing space in the "disk write-protected" error messsage
6953 * Cleaned up the error message printed when a non-interactive
6954 e2fsck needs to abort a check because the filesystem
6955 appears to be mounted.
6957 Added a new command-line utility, uuidgen, which will create and print
6960 Make debugfs's icheck command more robust by checking to make sure an
6961 inode has valid blocks before interarting over the inode's blocks.
6963 UUID generation now uses a random-based scheme whenever possible to
6964 prevent potential privacy problems.
6966 Man pages for all of the UUID functions in the lirbary were added.
6968 Fixed bug in fsck so it won't coredump if a filesystem not in
6969 /etc/fstab is given to it.
6971 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
6972 that most of the other mount utilities understands.
6974 Mke2fs will make a filesystem even if it appears mounted if the force
6977 Dumpe2fs has new command-line options which allow a filesystem expert
6978 to specify the superblock and blocksize when opening a filesystem.
6979 This is mainly useful when examining the remains of a toasted
6982 The badblocks program has been updated to display correctly on disks
6983 with large block numbers.
6985 The badblocks program no longer gives spurious errors when errors
6986 occur on non-block boundaries, which is common if the blocksize is
6989 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
6990 MKE2FS_SYNC environment variable is set. This is to work around a VM
6991 bug in the 2.0 kernel. I've heard a report that a RAID user was able
6992 to trigger it even using a 2.2 kernel, but hopefully it will not be
6993 needed for most Linux 2.2 users.
6995 Fixed miscellaneous documentation and man pages.
7000 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
7001 in e2fsck's pass1.c really should have been static.
7003 The return value of the uuid_compare() function was changed to make it
7004 match with the convetions used by strcmp, memcmp, and Paul Leach's
7005 UUID sample document.
7007 The "make depend" process has now been made more automated; it now
7008 automatically word-wraps the dependencies, and only replaces source
7009 Makefile.in if there has been a change in the dependencies. Also, a
7010 top-level "make depend" now recurses through all the subdirectories
7013 The Makefile in .../util has been changed so that subst is built using
7014 the native C compiler during a cross-compilation, since the subst
7015 program is only used during the build process. Also add an explicit
7016 rule to build util/subst by cd'ing to the correct directory and
7019 The man directories are defined in terms mandir, so that the configure
7020 script can override the location of the manual pages.
7022 The config files have been updated to recognize new machine types for
7023 both the i386 and alpha families.
7025 Fsck has been modified so that it will accurately create an
7026 fsck_instance even when the noexecute flag is set. This allows for
7027 accurate debugging of the fsck pass structure. Also, when the verbose
7028 flag is given twice, fsck will print debugging information about when
7029 fsck is waiting for jobs to finish.
7032 E2fsprogs 1.14 (January 9, 1999)
7033 ================================
7035 Fix the fstab parsing code so that it can handle blank lines and
7036 comment characters. Also, missing pass numbers need to be treated as
7039 Fixed a bug in e2fsck where under some circumstances (when e2fsck
7040 needs to restart processing after fixing an egregious inconsistency)
7041 it would try to access already freed memory.
7043 E2fsck now prints non-printable characters in directory entries and
7044 pathnames using '^' and 'M-' notation.
7046 Fixed chattr so that it will ignore symbolic links when doing
7047 recursive descent traversals. For both chattr and lsattr, no longer
7048 print the version string unless the -V option is given.
7050 Allow the system administrator to directly specify the number of
7051 inodes desired in the filesystem, for some special cases where this is
7054 Fix portability problems so that e2fsprogs can be compiled under Linux
7055 1.2 systems and Solaris systems.
7057 Update the config.guess file with a more recent version that will
7058 identify newer Linux platforms.
7063 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
7064 an inode number of zero is passed to them.
7066 E2fsprogs 1.13 (December 15, 1998)
7067 ==================================
7069 Fixed a bug in debugfs where an error messages weren't getting printed
7070 when the ext2 library routines to read inodes returned errors in the
7071 stat, cmri and rm commands.
7073 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
7074 provided, it won't create an inode table smaller than the minimum
7075 number of inodes required for a proper ext2 filesystem.
7077 Fsck now parses the /etc/fstab file directly (instead of using
7078 getmntent()), so that it can distinguish between a missing pass number
7079 field and pass number field of zero. This caused problems for
7080 diskless workstations where all of the filesystems in /etc/fstab have
7081 an explicit pass number of zero, and fsck could not distinguish this
7082 from a /etc/fstab file with missing pass numbers.
7084 E2fsck will create a /lost+found directory if there isn't one in the
7085 filesystem, since it's safer to create the lost+found directory before
7088 Fixed e2fsck so that it would detect bogus immutable inodes which
7089 happen to be sockets and FIFO files, and offer to clear them.
7091 If a filesystem has multiple reasons why it needs to be checked, and
7092 one of the reasons is that it is uncleanly mounted, e2fsck will print
7093 that as the reason why the filesystem is being checked.
7095 Cleaned up the output routines of mke2fs so that it doesn't overflow
7096 an 80 column display when formating really big filesystems.
7098 Added a sanity check to e2fsck to make sure that file descriptors 0,
7099 1, 2 are open before opening the hard disk. This avoids a problem
7100 where a broken program might exec e2fsck with those file descriptors
7101 closed, which would cause disastrous results if the kernel returns a
7102 file descriptor for the block device which is also used by FILE *
7105 Fixed up the e2fsck progress reporting functions so that the values
7106 reliably reach 100% at the completion of all of the e2fsck passes.
7108 Fixed minor documentation bugs in man pages and usage messages.
7113 Fixed a number of lint warnings in the ext2fs library and potential
7114 portability problems from other OS's header files that might define
7115 CPP macros for names like "max" and "min".
7117 ext2fs_badblocks_list_add() has been made more efficient when it needs
7118 to grow the bad blocks list.
7120 Fixed a bug in e2fsck which caused it to dereference a freed pointer
7121 just before exiting.
7123 Fixed the substition process for generating the mk_cmds and compile_et
7124 scripts so that they will work outside of the build tree.
7126 Add sanity check to e2fsck so that if an internal routine
7127 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
7128 and causing a core dump. This should never happen, but...
7130 E2fsprogs 1.12 (July 9, 1998)
7131 ==================================
7133 E2fsprogs now works with glibc (at least with the version shipped wtih
7134 RedHat 5.0). The ext2fs_llseek() function should now work even with
7135 i386 ELF shared libraries and if llseek() is not present. We also
7136 explicitly do a configure test to see if (a) llseek is in libc, and
7137 (b) if llseek is declared in the system header files. (See standard
7138 complaints about libc developers don't understand the concept of
7139 compatibility with previous versions of libc.)
7141 The ext2fs library now writes out the block group number in each of
7142 the superblock copies. This makes it easier to automatically
7143 determine the starting block group of the filesystem when the block
7144 group information is trashed.
7146 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
7147 which means that e2fsprogs will ignore the high 8 bits of the
7148 directory entry's name_len field, so that it can be used for other
7151 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
7152 E2fsprogs will now support filesystems with 64-bit sized files.
7154 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
7156 Added new program "e2label", contributed by Andries Brouwer. E2label
7157 provides an easy-to-use interface to modify the filesystem label.
7159 Fixed bug so that lsattr -v works instead of producing a core dump.
7161 Fixed a minor bug in mke2fs so that all groups with bad superblock
7162 backup blocks are printed (not just the first one).
7164 Mke2fs will check the size of the device, and if the user specifies a
7165 filesystem size larger than the apparent size of the device it will
7166 print a warning message and ask if the user wants to proceed.
7168 E2fsck has a new option -C, which sends completion information to the
7169 specified file descriptor. For the most part, this is intended for
7170 programs to use, although -C 0 will print a spinning character to the
7171 stdout device, which may be useful for users who want to see something
7172 happening while e2fsck goes about its business.
7174 Fixed a bug in e2fsck which could cause a core dump when it needs to
7175 expand the /lost+found directory, and sometimes the bitmaps haven't
7176 been merged in. Also fixed a related bug where ext2fs_write_dir_block
7177 was used to write out a non-directory block. (Which would be bad on a
7178 non-Intel platform with byte swapping going on.)
7180 Fixed bug in e2fsck where it would print a "programming error" message
7181 instead of correctly identifying where a bad block was in used when
7182 the bad block was in a non-primary superblock or block group
7183 descriptor. Also fixed a related bug when sparse superblocks are in
7184 use and there is a bad block where a superblock or block group
7185 descriptor would have been in a group that doesn't include a
7188 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
7189 the block group descriptor table is corrupt, it was possible to try to
7190 allocate a huge array, fail, and then abort e2fsck.
7191 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
7192 and subsitutes reasonable values if the descriptors are obviously bogus.
7194 If e2fsck finds a device file which has the immutable flag set and the
7195 i_blocks beyond the normal device number are non-zero, e2fsck will
7196 offer to remove it, since it's probably caused by garbage in the inode
7199 When opening a filesystem, e2fsck specially checks for the EROFS error
7200 code, and prints a specific error message to the user which is more
7203 If the filesystem revision is too high, change the e2fsck to print
7204 that this is either because e2fsck is out of date, or because the
7205 superblock is corrupt.
7207 E2fsck now checks for directories that have duplicate '.' and '..'
7208 entries, and fixes this corruption.
7210 E2fsck no longer forces a sync of the filesystem (with attendant sleep
7211 calls) at all times. The ext2fs_flush() function now performs a sync
7212 only if it needed to write data blocks to disk.
7214 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
7215 certain errors would not be properly reported.
7217 Updated and expanded a few points in the man pages which users
7218 complained wheren't explicit enough.
7220 Added special case byte-swapping code if compiling on the PowerPC, to
7221 accomodate the strange big-endian variant of the ext2 filesystem that
7222 was previously used on the PowerPC port.
7228 Removed C++ keywords from the ext2fs libraries so that it could be
7231 E2fsck's internal organization has now been massively reorganized so
7232 that pass*.c don't have any printf statements. Instead, all problems
7233 are reported through the fix_problem() abstraction interface. E2fsck
7234 has also been revamped so that it can be called as a library from a
7237 Added new fileio primitives in libext2fs for reading and writing
7238 files on an unmounted ext2 filesystem. This interface is now used by
7241 Added a new libext2fs function for mapping logical block numbers of
7242 a file to a physical block number.
7244 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
7245 a block, zeros it, and updates the filesystem accounting records
7248 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
7249 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
7251 The libext2fs functions now use a set of memory allocation wrapper
7252 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
7253 instead of malloc, free, and resize. This makes it easier for us to
7254 be ported to strange environments where malloc, et. al. aren't
7255 necessarily available.
7257 Change the libext2fs fucntion to return ext2-specific error codes
7258 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
7259 and depending on the existence of system error codes (such as EEXIST
7262 Renamed io.h to ext2_io.h to avoid collision with other OS's header
7265 Add protection against ext2_io.h and ext2fs.h being included multiple
7268 The types used for memory lengths, etc. have been made more portable.
7269 In generla, the code has been made 16-bit safe. Added Mark
7270 Habersack's contributed DOS disk i/o routines.
7272 Miscellaneous portability fixes, including not depending on char's
7275 The io_channel structure has a new element, app_data, which is
7276 initialized by the ext2fs routines to contain a copy of the filesystem
7279 ext2fs_check_directory()'s callback function may now return the error
7280 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
7281 really do the checking, despite the presence of the callback function.
7284 E2fsprosg 1.11 (June 17, 1997)
7285 ==============================
7287 Fixed e2fsck to detect (previously ignored) conflicts between the
7288 superblock or block group descriptors and block bitmaps, inode
7289 bitmaps, and inode tables.
7291 Fixed bug in e2fsck so that when the message printed out when a block
7292 or inode bitmap conflicts with other data, it has the correct group
7295 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
7296 to badblocks. This meant that not all of the filesystem was being
7297 tested for bad blocks!
7299 Fixed an array boundary overrun case which cropped up in
7300 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
7303 Adjusted the number of columns printed by mke2fs when displaying the
7304 superblock backups to avoid running over 80 columns when making a
7305 really big filesystem.
7307 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
7308 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
7309 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
7314 Fixed install rule in lib/ss so that ss_err.h is actually getting
7317 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
7318 bassed back to the caller.
7320 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
7321 setting the current inode number (which meant this function wasn't
7324 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
7325 blocks in the bitmap when increasing the size of the bitmap.
7327 Changed the initial number of blocks allocated by ext2fs_init_dblist()
7328 to be more realistic.
7330 Added a new function ext2fs_allocate_group_table, which sets up the
7331 group descriptor information (and allocates inode and block bitmaps,
7332 and inode tables for a particular group). The function was created by
7333 factoring out code form ext2fs_allocate_tables().
7335 Added a new function ext2fs_move_blocks which takes a bitmap of the
7336 blocks to be moved, and moves them to another location on the
7339 Make the unix_io channel's io_channel_flush implementation calls sync()
7340 to to flush the kernel buffers to disk.
7342 Added a new function ext2fs_dblist_count returns the number of
7343 directory blocks in dblist.
7346 E2fsprogs 1.10 (April 24, 1997)
7347 ===============================
7349 Mke2fs once again defaults to creating revision #0 filesystems, since
7350 people were complaining about breaking compatibility with 1.2 kernels.
7351 Warning messages were added to the mke2fs and tune2fs man pages that
7352 the sparse superblock option isn't supported by most kernels yet (1.2
7353 and 2.0 both don't support parse superblocks.)
7355 Added new flag to mke2fs, -R <raid options>, which allows the user to
7356 tell mke2fs about the RAID configuration of the filesystem. Currently
7357 the only supported raid option is "stride" which specifies the width
7360 Fixed bug in e2fsck where pass1b would bomb out if there were any
7361 blocks marked bad in the inode table.
7363 Fixed rare bug in mke2fs where if the user had a very unlucky number
7364 of blocks in a filesystem (probability less than .002) the resulting
7365 filesystem would be corrupt in the last block group.
7367 Fixed bug where if e2fsck tried to allocate a block to fix a
7368 filesystem corruption problem and the filesystem had no free blocks,
7369 ext2fs_new_block() would loop forever.
7371 The configure script now checks explicitly to see if "-static" works,
7372 since that can't be assumed to be true --- RedHat doesn't install
7373 libc-static by default.
7375 Fixed bug in libext2's block iterator functions where under some
7376 cirmcustances, file with holes would cause the bcount parameter to the
7377 callback function to be incorrect. This bug didn't affect any of
7378 e2fsprogs programs, but it was discovered by Paul Mackerras, the
7379 author of the PPC boot loader.
7381 Removed use of static variables to store the inode cache in libext2fs.
7382 This caused problems if more than one filesystem was accessed via
7383 libext2fs (static variables in libraries are generally a bad idea).
7384 Again, this didn't affect e2fsprogs programs, but it was discovered by
7387 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
7388 will compile cleanly with 1.2.13 kernels (even with a.out shared
7394 Added new functions to duplicate an ext2 filesystem handle, and its
7395 associated substructure. New functions: ext2fs_dup_handle(),
7396 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
7397 Other structures, such as the io_channel and the inode_cache, now have
7398 a ref count so that they only get freed when they are no longer used
7399 by any filesystem handle. (These functions were added as part of the
7400 development effort for an ext2 resizer).
7402 E2fsprogs 1.09 (April 14, 1997)
7403 ===============================
7405 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
7406 accidentally introduced in the 1.08 release. The overhead calculation
7407 was accidentally removed, which caused ext2fs_initialize() to not
7408 notice when the filesystem size needed to be adjusted down because
7409 there wasn't enough space in the last block group.
7411 Fixed bug in version parsing library routine; it was always parsing
7412 the library version string, instead of using the passed-in string.
7414 Clarified chattr man page.
7416 E2fsprogs 1.08 (April 10, 1997)
7417 ===============================
7419 E2fsck 1.07 was very slow when checking very large filesystems with a
7420 lot of files that had hard links (i.e., news spools). This was fixed
7421 by seriously revamping the icount abstraction. Added a formal test
7422 suite for the icount abstraction.
7424 Debugfs now has a "-l" option to the "ls" command, which lists the
7425 inode number, permissions, owner, group, size, and name of the files
7428 Fix a bug in e2fsck where when a directory had its blocks moved to
7429 another location during the pass 1b processing, the directory block
7430 list wasn't updated, so pass 2 wouldn't check (and correct) the
7431 correct directory block.
7433 E2fsck will now treat inodes which contain blocks which are claimed by
7434 the filesystem metadata by treating them as multiply claimed blocks.
7435 This way, the data in those blocks can be copied to a new block during
7436 the pass 1b--1d processing.
7438 E2fsck will attempt to determine the correct superblock number and
7439 display it in the diagnostic and warning messages if possible.
7441 Add support for a new (incompatible) feature, "sparse_super". This
7442 feature reduces the number of blocks which contain copies of backup
7443 superblocks and block group descriptors. (It is only an incompatible
7444 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
7445 support a new -s option; e2fsck will recognize filesystems built with
7446 this feature turned on.
7448 E2fsck now checks the library to make sure is the correct version,
7449 using new library functions. (This helps to diagnose incorrectly
7450 installed e2fsprogs distributions.)
7452 Dumpe2fs now prints more information; its now prints the the
7453 filesystem revision number, the filesystem sparse_super feature (if
7454 present), the block ranges for each block group, and the offset from
7455 the beginning of the block group.
7457 Mke2fs now distributes the inode and block bitmap blok so that the
7458 won't be concentrated in one or two disks in RAID/striping setups.
7459 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
7460 choose the largest blocks per group that be chosen. (For 2k blocks,
7461 you can have up to 16384 blocks/group; for 4k blocks, you can have up
7462 to 32768 blocks/group.) Previously mke2fs would not allow
7463 specification of more than 8192 blocks per group, even if you were
7464 using a 2k or 4k block group.
7469 Added a new function ext2fs_create_icount2() which takes a "hint"
7470 argument. This hint argument presets the icount array with the list
7471 of inodes which actually need to be in the icount array. This really
7472 helps to speed up e2fsck.
7474 Added a new function ext2fs_icount_validate() which checks the rep
7475 invariant for the icount structure. This is used mostly for testing.
7477 The error mesasage given when a bad inode number is passed to
7478 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
7479 EXT2FS_UNMARK_ERROR).
7481 Added a new function ext2fs_set_dir_block which sets the block of a
7482 dblist entry, given the directory inode and blockcnt.
7484 Added a new function ext2fs_get_library_version() which returns the
7485 current library version, and ext2fs_parse_version_string() which
7486 returns a version number based on a e2fsprogs version string.
7488 The icount functions will return EINVAL if the passed in inode number
7491 E2fsprogs 1.07 (March 9, 1997)
7492 ==============================
7494 E2fsck is now uses much less memory when checking really large
7495 filesystems (or rather, filesystems with a large number of inodes).
7496 Previously a filesystem with 1 million inodes required 4 megabytes of
7497 memory to store inode count statistics; that storage requirement has
7498 now been reduced to roughly half a megabyte.
7500 E2fsck can now properly deal with bad blocks appearing inside the
7501 inode table. Instead of trying to relocate the inode table (which
7502 often failed because there wasn't enough space), the inodes in the bad
7503 block are marked as in use.
7505 E2fsck will automatically try to use the backup superblocks if the
7506 primary superblocks have a bad magic number or have missing meta-data
7507 blocks (or meta-data blocks which are out of range).
7509 E2fsck's pass 3 has been made more efficient; most noticeable on
7510 filesystems with a very large number of directories.
7512 Completely revamped e2fsck's system of printing problem reports. It
7513 is now table driven, to make them more easily customizeable and
7514 extendable. Error messages which can be printed out during preen mode
7515 are now one line long.
7517 Fixed e2fsck's filesystem swapping code so that it won't try to swap
7518 fast symbolic links or deleted files.
7520 Fixed e2fsck core dumping when fixing a filesystem which has no
7521 directories (not even a root directory).
7523 Added a check to e2fsck to make sure that the length of every
7524 directory entry is a multiple of 4 (since the kernel complains if it
7527 Added a check to e2fsck to make sure that a directory entry isn't a
7528 link to the root directory, since that isn't allowed.
7530 Added a check to e2fsk to now make sure the '.' and '..' directory
7531 entries are null terminated, since the 2.0 kernel requires it.
7533 Added check to write_bitmaps() to make sure the superblock doesn't get
7534 trashed if the inode or block bitmap is marked as being block zero.
7536 Added checking of the new feature set fields in the superblock, to
7537 avoid dealing with new filesystem features that this package wasn't
7540 Fixed a fencepost error in ext2fs_new_block() which would occasionally
7541 try to allocate a block beyond the end of a filesystem.
7543 When the UUID library picks a random IEEE 802 address (because it
7544 can't find one from a network card), it sets the multicast bit, to
7545 avoid conflicting with a legitimate IEEE 802 address.
7547 Mke2fs now sets the root directory's owner to be the real uid of the
7548 user running mke2fs. If the real uid is non-zero, it also sets
7549 the group ownership of the root directory to be the real group-id of
7550 the user running mke2fs.
7552 Mke2fs now has more intelligent error checking when it is given a
7553 non-existent device.
7555 When badblocks is given the -vv option, it now updates the block that
7556 it is currently testing on every block.
7558 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
7559 currently correctly if PATH wasn't already set.
7561 Shared libraries now built with dependencies. This allows the shared
7562 library files to be used with dlopen(); it also makes the transition
7563 to libc 6 easier, since ld.so can tell which libc a particular shared
7564 library expects to use.
7569 Added new abstraction (defined in dblist.c) for maintaining a list of
7570 blocks which belongs to directories. This is used in e2fsck and other
7571 programs which need to iterate over all directories.
7573 Added new functions which test to see if a contiguous range of blocks
7574 (or inodes) are available. (ext2fs_*_bitmap_range).
7576 Added new function (ext2_inode_has_valid_blocks) which returns true if
7577 an inode has valid blocks. (moved from e2fsck code).
7579 Added new function (ext2fs_allocate_tables) which allocates the
7580 meta-data blocks as part of initializing a filesystem. (moved from
7583 Added a new I/O manager for testing purposes. It will either allow a
7584 program to intercept I/O requests, or print debugging messages to
7585 trace the activity of a program using the I/O manager.
7587 The badblocks_list functions now store the bad blocks in a sorted
7588 order, and use a binary search to speed up badblocks_list_test.
7590 The inode scan function ext2fs_get_next_inode() may now return a soft
7591 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
7592 those cases where part of an inode table is missing or there is a bad
7593 block in the inode table.
7595 Added a new function (ext2fs_block_iterate2) which adds new arguments to
7596 the callback function to return a pointer (block and offset) to the
7597 reference of the block.
7599 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
7600 application to jump to a particular block group while doing an inode
7603 The badblocks list functions were renamed from badblocks_* to
7604 ext2fs_badblocks_*. Backwards compatibility functions are available
7605 for now, but programs should be modified to use the new interface.
7607 Some of the library functions were reorganized into separate files to
7608 reduce the size of some programs which statically link against the
7611 Put in some miscellaneous fixes for the Alpha platform.
7614 E2fsprogs 1.06 (October 7, 1996)
7615 ================================
7617 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
7618 smash the backup copies in ext2fs_close(). (The problem was that when
7619 e2fsck -p discovered the problem, while it was closing the filesystem
7620 and exiting, it was also blowing away the backup superblocks on the
7621 disk, which was less than friendly.) We now make it the case that we
7622 only write out the backup superblock and the back block descriptors if
7623 the filesystem is completely free from problems.
7625 Fixed a bug in block_interate in the lib/ext2fs library which caused
7626 e2fsck to fail on GNU Hurd-created filesystems.
7628 Add support for Linux/FT's bootloader, which actually uses
7629 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
7632 Add support for the "A" (no atime update) attribute. (Note: this
7633 attribute is not yet in production kernels.)
7635 The test suite is not automatically run when doing a "make all" from
7636 the top level directory. Users should manually run "make check" if
7637 they wish to run the test suite.
7639 Upon a preenhalt(), make the printed message more explicit that
7640 running e2fsck "MANAULLY" means without the -p or -a options.
7642 In e2fsck, if a disconnected inode is zero-length, offer to clear it
7643 instead of offering to connect it to lost+found.
7645 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
7646 e2fsck to be run over it, change e2fsck to explicitly display this
7649 For dumpe2fs and e2fsck, cause the -V option to print out which
7650 version of the ext2fs library is actually getting used. (This will
7651 help detect mismatches of using a 1.06 utility with a 1.05 library,
7657 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
7658 the naming convention.
7660 In ext2fs_initialize(), make sure the description for the inode bitmap
7661 is correctly initialize.
7663 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
7665 E2fsprogs 1.05 (September 7, 1996)
7666 ==================================
7668 Add support for new fields in the ext2 superblock --- volume name,
7669 volume UUID, and last mounted field. Dumpe2fs displays these fields,
7670 tune2fs and mke2fs allows you to set them. E2fsck will automatically
7671 generate a UUID for those volumes that don't have them.
7673 Put in support for e2fsck to recognize HURD specific ext2 features ---
7674 most notably, the translator block. The e2fsprogs tools will now use
7675 the creator_os field in the superblock to correctly handle different
7676 OS-specific variants of the ext2 filesystem.
7678 E2fsck now fixes inodes which have a the deletion time set, but which
7679 have a non-zero i_link_count field by offering to clear the deletion
7680 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
7681 ext2 kernel behavior) and offered to unlink the file.
7683 If e2fsck sets the clean bit, but nothing else, set the exit code
7684 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
7685 set the filesystem valid bit when it was previously cleared. :-) This
7686 was needed to make the HURD fsck driver happy.
7688 If the user refuses to attach an unattached inode, e2fsck will no
7689 longer set the inode's link count. Otherwise, the inode would end up
7690 getting marked as unused, which might cause loss of data later.
7692 Make the message issued by e2fsck when the superblock is corrupt less
7693 confusing for users. It now mentions that another reason for the
7694 "corrupt superblock" message might be that the partition might not be
7695 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
7697 Make the libext2 library more robuest so that e2fsck won't coredump on
7698 an illegal superblock where the blocksize is zero. (f_crashdisk is
7701 By default, create filesystems where the default checkinterval is 6
7702 months (180 days). Linux servers can be robust enough that 20 reboots
7703 can be a long, long time.
7705 Added configure flag --enable-old-bitops, which forces the bitops to
7706 use the old (native) bitmask operations. By default on the sparc
7707 platform, the standard ext2 bit ordering is now used.
7709 Added a new feature to e2fsck to byte-swap filesystems; this can be
7710 used to convert old m68k filesystems to use the standard byte-order
7711 storage for the superblock, inodes, and directory blocks. This
7712 function is invoked by using the '-s' option to e2fsck.
7714 Debugfs's "dump" command has been enhanced so that it writes out the
7715 exact size of the file so that the nulls at the end of the file are
7716 eliminated. The command also accept a new "-p" option which will
7717 attempt preserve to preserve the ownernship, permissions, and
7718 file modification/access times.
7720 Debugfs has two new options, -f and -R. The -R option allows the user
7721 to execute a single debugfs command from the command line. The -f
7722 option allows the user to specify a "command file" containing debugfs
7723 commands which will get executed.
7725 Dumpe2fs now pretty prints the check interval, instead of just
7726 printing the check interval as a number of seconds.
7728 Fix bugs in debugfs: the params command when no filesystem is opened
7729 no longer causes a core dump. It is now possible to unlink a file
7730 when a pathame containing a '/' is specified.
7732 Tune2fs has a new -C option which sets the number of times the
7733 filesystem has been mounted.
7735 Fix the chattr '-v' option so that it actually works. Chattr was
7736 being buggy about the -v option parsing.
7741 The directory lib/uuid contains a set of library routines to generate
7742 DCE compatible UUIDs.
7744 Extended ext2fs_namei() to handle symbolic links. Added new function
7745 ext2fs_nami_follow() which will follow last symbolic link in the case
7746 where the pathname points to a sym link.
7748 The ext2fs_block_iterate function will now return the HURD translator
7749 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
7750 iterator to return data blocks only. The ext2fs.h file now defines
7751 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
7752 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
7753 count field of the iterator callback function.
7755 The test script driver now takes an optional second argument, which is
7756 the test case to be run. This allows you to run a test case without
7757 needing to run the entire test suite.
7759 On Linux ELF systems, install the .so files in the correct places
7760 (/usr/lib). The .so files must be stored in the same directory as the
7763 Fixed miscellaneous HURD compilation issues with header file being
7764 included in the right order.
7766 Fixed debugfs so that it resets optind to zero, not one, since setting
7767 optind to zero is more correct.
7770 E2fsprogs 1.04 (May 16, 1996)
7771 =============================
7773 First "official" (1.03 was a limited release only) to support building
7774 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
7777 This package includes a RPM specs file, that it can be built using the
7778 RedHat Package Manager.
7780 E2fsck now prints a hint that if there are lots of incorrectly located
7781 inode bitmaps, block bitmaps, and inode table blocks, the user might
7782 want to try using e2fsck -b 8193 first, to see if that fares any
7785 For ext2 filesystem written with the hurd, debugfs will now print out
7786 the translator field when printing an inode structure.
7788 Lots of miscellaneous linking/installation cleanups:
7790 Libraries are now linked using a relative pathname, instead of
7791 relying on -L working correct. It doesn't, in many cases, including
7792 current versions of GNU ld. This guarantees that the build tree is
7793 linking with the right libraries, instead of the ones installed in
7796 Header files, man pages, and the et/ss shell scripts are now
7797 generated using a custom substitution script, instead of relying on
7798 the configure script. This prevents needless recompilation of
7799 files; in addition, the custom substitution script is much faster.
7801 e2fsck may now be linked dynamically, by using the
7802 --enable-dynamic-e2fsck flag to configure. This is not recommended,
7803 since it increases e2fsck's dependence on other files, but some
7804 people need to save disk space, and other critical programs on their
7805 systems were being linked dynamically anyway.
7807 Programs such as fsck which didn't need to be linked against
7808 libext2fs (or mke2fs which didn't need to be linked against libe2p)
7809 only link against libraries they actually need. Otherwise, those
7810 programs would require the presense of libraries that otherwise
7811 could be removed from a rescuse diskette.
7813 The ss include files are now installed correctly so they can
7814 actually be used by another package.
7816 If the profiling libraries are built, they are now installed on a
7817 "make install-libs".
7820 E2fsprogs 1.03 (March 27, 1996)
7821 ===============================
7823 Change the m68k bit numbering for bitmasks to match the bit numbering
7824 used by all other ext2 implementations. (This change was requested by
7825 the m68k kernel development team.)
7827 Support (in-development) filesystem format revision which supports
7828 (among other things) dynamically sized inodes.
7830 Fixed a bug in the ext2 library so that an intelligent error is
7831 returned if mke2fs is run with a ridiculously small number of blocks
7834 Fixed a bug in the ext2 library which required that the device be
7835 openable in read/write mode in order to determine its size. This
7836 caused e2fsck -n to require read/write access when it was not
7837 previously necessary.
7839 Fixed a bug in e2fsck which casued it to occasionally fail the test
7840 suite depending on which version of the floating point library it was
7843 Fixed a bug in e2fsck so that it now halts with a fatal error when
7844 certain superblock consistency checks fail. Previously it continued
7845 running e2fsck, with some potential confusing/damaging consequences.
7847 Added new flag to fsck which allows the root to be checked in parallel
7848 with other filesytems. This is not the safest thing in the world to
7849 do, but some system administrators really wanted it.
7851 Fixed -Wall flames in lib/ss.
7854 E2fsprogs 1.02 (January 16, 1996)
7855 =================================
7857 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
7859 Change e2fsck to print statistics of how many non-contiguous files are
7860 on the system. Note that a file which is larger than 8k blocks, it is
7861 guaranteed to be non-contiguous.
7863 In mke2fs, print a warning message if a user tries to format a whole
7864 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
7865 whole disk, the -F (force) option forces mke2fs to format a whole disk
7868 Fix a bug in fsck where in some cases it might start checking
7869 partitions in the next pass before it finishes checking partitions in
7870 the current pass. This still won't cause two partitions on the same
7871 disk will be checked, so it's rarely a problem in real life.
7873 Patch lsattr so that it won't hang when checking a named pipe.
7875 Minor compilation fixes:
7876 * Fix the order of libraries that were linked in debugfs.
7877 * Allow the sources to be compiled with -ansi turned on.
