1 E2fsprogs 1.41.1 (as of August 23, 2008) commit id baf8ab98
2 ============================================================
4 Many people are forgetting to update their mke2fs.conf file, and this
5 causes ext3, ext4, and ext4dev filesystems won't get created with the
6 proper features enabled. We address this in two ways. First, mke2fs
7 will issue a warning if there is not definition for an ext3, ext4, or
8 ext4dev filesystem and the user is trying to create such a filesystem
9 type. Secondly, when installing from a source build, "make install"
10 will provide basic configuration file handling for /etc/mke2fs.conf.
11 If it exists, and does not mention ext4dev, it will be moved aside to
12 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
13 be installed. If the existing /etc/mke2fs.conf file does mention
14 ext4dev, then "make install" will install official mke2fs.conf file as
15 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
16 they should look to see if any changes need to be merged.
18 Mke2fs and tune2fs now print the correct usage message describing the
19 maximum journal size. (Addresses Debian Bug: #491620)
21 The blkid library will now recognize MacOS hfsx filesystems, and
22 correctly extract the label and uuid for hfs, hfsx, and hfsplus
23 filesystems. (Addresses Sourceforge Feature Requests: #2060292)
25 Resize2fs will now properly close out the "updating inode references"
26 progress bar so there is a newline printed before printing the final
27 "resize is successful" message.
29 Resize2fs will now correctly handle filesystems with extents and/o
30 uninitialized block groups correctly when file/directory blocks need
31 to relocated (i.e., when shrinking a filesystem or if the resize_inode
32 is not present). To support this, the ext2fs library now supports
33 initializing inode and block bitmaps that are not yet initialized when
34 allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
35 addition, e2fs_block_iterate2() can now support changing the location
36 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
37 been optimized to avoid creating unnecessary new extents when updating
38 the location of blocks in the extent tree. This will also help out
39 e2fsck's recovery of obscurely corrupted filesystems with extents,
40 when blocks are claimed by multiple inodes.
42 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
43 debugfs programs to not be able to read e2image files; the signed
44 vs. unsigned bug in the code which read bitmaps from the e2image has
45 been fixed. (Addresses Debian Bug: #495830)
47 Resize2fs is now correctly managing the directory in-use counts when
48 shrinking filesystems and directory inodes needed to be moved from one
49 block group to another. This bug has been around since e2fsprogs
50 1.26, and is largely harmless, but does cause a filesystem corruption
51 which will be flagged by e2fsck after the filesystem has been shrunk.
53 E2fsck will no longer issue spurious complaints about the inode size
54 caused by very large extent-based files, and by blocks reallocated
55 using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
56 Kernel Bugzilla: #11341)
58 Mke2fs will now set the creation timestamp on the lost+found directory
59 and the root directory. (More generally, all new inodes created using
60 the ext2fs library will correctly set the creation timestamp.)
62 E2fsck now correctly calculates ind/dind/tind statistics in the
63 presence of extent-based files. In addition, "e2fsck -v" will report
64 statistics of the depth of extent trees in the filesystem. E2fsck can
65 also give an inode fragmentation report using "e2fsck -E fragcheck"
66 which can be useful when debugging the kernel block allocation
69 Blkid had a number of cache validation bugs in libblkid that have been
70 fixed. (Addresses Debian Bug: #493216)
72 Debugfs's htree command now correctly understands extent-based
73 directories. It will also print out the minor hash as well as the
76 The error message printed by "tune2fs -I" if the inode size was too
77 small was rather confusing, so it has been improved. Also, we won't
78 try to create an undo log until we know that command-line-specified
79 parameters such as "tune2fs -I <inode size>" are valid.
81 Mke2fs will correctly enforce the prohibition against features
82 (specifically read-only features) in revision 0 filesystems. (Thanks
83 to Benno Schulenberg for noticing this problem.)
85 Mke2fs previously would occasionaly create some slightly non-optimally
86 placed inode tables; this bug has been fixed.
88 Given some filesystems found "in the wild" that had non-zero block
89 group checksums even though the uninit_bg/gdt_sum feature was not
90 enabled, e2fsck would issue spurious error messages. Teach
91 ext2fs_group_desc_csum_verify() to ignore the block group checksum
92 entirely if the feature flag is not set. (Addresses Debian Bug:
95 The blkid program will now print out a user-friendly listing of all of
96 the block devices in the system and what they contain when given the
97 -L option. (Addresses Debian Bug: #490527)
99 Typographical errors in various program strings and usage messages
100 have been fixed; most of these were pointed out by the e2fsprogs
101 message catalog translators. (Thanks, translators!)
103 Update and clarified various man pages, as well as some typographical
104 errors in the libext2fs texinfo file.
106 Fixed various Debian packaging issues --- see debian/changelog for
109 Add Indonesian and update French, Polish, Dutch, German, Sweedish,
110 Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
116 Fix portability problem with the badblocks group; for systems that
117 don't have nanosleep(), try using usleep() instead.
119 The "make check" target in the e2fsck directory now sets
120 LD_LIBRARY_PATH before running the various e2fsck internal library
123 The crc32 regression test in the e2fsck library is now portable to
124 greater varienty of environments, including big-endian systems and
125 when cross-building e2fsprogs for embedded systems. (Addresses
126 Sourceforge Bug: #2019287)
128 The ext2fs_extent_set_bmap() had some bugs when setting the first
129 block in a file, or when replacing a single block extent. Those cases
130 fortunately were came up relatively rarely when e2fsck was checking
131 files, but caused some problems when resize2fs was shrinking
134 Various ext2fs library functions --- ext2fs_initialize() and
135 ext2fs_extent_open() --- now correctly free allocated memory to avoid
136 memory leaks in all of their error return paths.
138 Ext2ed was failing to build because masix support had been removed in
139 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
141 The configure script now respects the LDFLAGS environment variable if
142 it is set when configure is called. (Addresses Sourceforge Feature
145 Libuuid is now more portable to the Windows platform. (Addresses
146 Sourceforge Feature Request: #1937287)
148 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
149 bare echo commands so that configure flags such as --quiet work
150 correctly. (Addresses Sourceforge Patches: #2058794)
152 A few uses of sprintf have been removed from the ext2fs library to
153 make life easier for bootloaders with a limited libc environment.
154 (Addresses Sourceforge Bug: #2049120)
156 The ext2fs_read_inode() checks the validity of the inode number passed
157 to it earlier, to avoid doing some needless work when it would fail
160 The ext2fs_open() checks the validity of the blocksize parameter
161 passed to it earlier, to avoid doing some needless work when it would
164 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
165 top-level Makefile. That automatic rule is used to better support
166 SCCS, but it caused problems for a particular niche distribution which
167 likes to use configure.sh files to store the configure options used to
168 build a package. Unfortuntaely GNU make will use the configure.sh to
169 replace the configure script, resulting in a self-inflicted fork bomb
170 leading to an out-of-memory crash.
172 E2fsprogs is now more portable to Solaris.
173 * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
175 * Scripts do not assume that /bin/true is always in /bin
176 * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
177 * Flush stdio handles before calling setbuf(), since Solaris will
178 discard any pending output to the stream.
179 * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
180 picky about which C compiler can beused for SUSv3 conformance.
181 Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
182 and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
183 Since we need some SUSv3 functions, consistently use SUSv3 so
184 that e2fsprogs will build on Solaris using c99.
185 * Solaris C99 does not support varargs C preprocessor macros
186 * Solaris header files pollute the C namespace if in/netinet.h
187 is included, which conflicts with e2fsprogs' use of the kmem_cache_t
189 * Solaris ships with a pathetically ancient shell in /bin/sh so we
190 avoid the use of various more avanced shell constructs such as $().
192 To support old GNU C compilers don't use C99/C++ comments, but only
193 K&R style comments, and don't try to use __builtin_expect if __GNUC__
194 is less than 3. (__builtin_expect is only supported for gcc versions
195 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
196 this is an optimization, we only try to use __builtin_expect for gcc 3
199 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
200 __LITTLE_ENDIAN, which are only defined by glibc's header files and
201 hence isn't portable.
203 For the convenience for some distributions that need a static tune2fs,
204 the Makefile for misc/ now has a tune2fs.static target.
207 E2fsprogs 1.41 (July 10, 2008)
208 ==============================
210 Add support for ext4 filesystem features, in particular extents,
211 uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
212 support for checking journal checksums. Debugfs will print new
213 superblock and inode fields that were defined for ext4. For example,
214 the nanosecond and i_version fields of an inode, and the
215 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
216 Note: Resize2fs doesn't currently support the combination of flex_bg
217 and !resize_inode. (Addresses Debian Bug: #388452, #425477)
219 Tune2fs can support migrating a filesystem from using 128 byte inodes
220 to 256 byte inodes, so it can take advantage of the full features of
223 Add support for "undo" support. E2fsck and mke2fs can optionally
224 record an undo log which can replayed by the program e2undo.
226 E2fsck could damage a filesystem by trying to relocate inode tables
227 due to corrupted block group descriptors, where the attempted inode
228 table relocation would do far more harm than good. E2fsck has been
229 fixed to detect this these sorts of corrupted block group descriptors
230 much earlier in e2fsck processing, so it can try to use the backup
231 superblock and block group descriptors first. This should be a much
232 better strategy for recovering these types of corrupted filesystems.
233 (Addresses Sourceforge Bug: #1840291)
235 E2fsck will display a more understandable message when the last check
236 field in the superblock is in the future. (Addresses Debian Bug:
239 E2fsck now performs more extensive and careful checks of extended
240 attributes stored in the inode.
242 Enhance mke2fs to print a more explanatory error message when
243 ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
246 Fix mke2fs to use a default block size of 4k when formatting an
247 external journal device. This is done by using a fixed filesystem
248 type list that consists only of the single filesystem type "journal"
249 when looking up configuration keys in /etc/mke2fs.conf. (Addresses
252 Speed up how mke2fs writes the journal data blocks by writing the disk
253 blocks in larger chunks.
255 Fix blkid handling of stale devices. Fix a bug which could cause a
256 core dump while garbage collecting the blkid cache, and assure that
257 blkid_find_dev_with_tag() never returns a non-existent device. Also,
258 if a filesystem is found at a new /dev location, eliminate any
259 duplicate stale entries which can not be verified.
260 (Addresses-Debian-Bugs: #487758, #487783)
262 Add more paranoid checks for LVM volumes and swap partitions in
263 blkid's probe function, to reduce the chances of false positives.
265 The mke2fs program now has a much more sophisticated system for
266 controlling configuration parameters of a newly created filesystem
267 based on a split filesystem and usage type system. The -t option to
268 mke2fs was a deprecated alias to -c; it now specifies a filesystem
269 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
270 separated usage list. The filesystem type information and type
271 information is used to extract configuration parameters from the
272 /etc/mke2fs.conf file.
274 The mke2fs program will no longer complain and request the -f option
275 when the user tries to create a filesystem with greater than 2**31
278 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
279 adjust the mke2fs.conf file so filesystems for the Hurd are created
280 with a blocksize of 4096 and inode size of 128, which is all it knows
281 how to handle. (Addresses Debian Bug: #471977)
283 Mke2fs will always make sure that lost+found always has at least 2
284 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
286 Resize2fs will now print the minimum needed filesystem size if given
287 the -P option, and will resize the filesystem to the smallest possible
288 size if given the -M option.
290 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
291 blocks are consumed during an off-line resize.
293 The "ls" command in debugfs now supports the -p option, which causes
294 it to quote the filenames so that spaces or tabs in directory entries
295 are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
296 Sourceforge Feature Request: #1201667)
298 Fix a potential off-by-one buffer oveflow in the fs_device_name in an
301 The chattr program will return a non-zero exit code in case of
302 failures, and error messages can be suppressed with the -f option.
303 (Addresses Red Hat Bugzilla: #180596)
305 Fix a bug in badblocks which caused it to overrun an array and likely
306 crash if more than 8 test patterns are specified using the -t option.
307 (Addresses Debian Bug: #487298)
309 Add support to badblocks to limit how quickly it reads from the disk
310 drive (so it can be used for background scrubbing), and so it will
311 abort after finding a given number of errors.
313 Remove support for the legacy big-endian filesystem format which only
314 existed on extremely long-dead PowerPC kernels almost a decade ago.
316 Remove MASIX support from e2fsprogs.
318 Add I/O statistics reporting to e2fsck.
320 Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
323 Fixed various Debian packaging issues --- see debian/changelog for
324 details. (Addresses Debian Bugs: #487443, #487675, #490003)
326 Fixed spelling mistakes, typos, and otherwise clarified man pages.
327 (Addresses Debian Bugs: #393313, #487849, #440983, #440981)
332 Factor out bitmap code in preparation for adding 64-bit new-style
335 Fix gcc -Wall warnings
337 Fix the pkg-config files so that private librares are specified in
340 Fix the libext2fs.texinfo manual so it builds with modern versions of
343 Silence the makefile from showing the awk command used to build the
345 Clean up the badblocks group so to make it more portable and robust.
347 Avoid using predictable filenames in /tmp in blkid's regression test
348 suite. Also remove bashism's in the regression test script.
350 If the configure script is given --with-diet-libc, don't use thread
351 local storage, since diet libc doesn't support TLS. (Addresses
352 Sourceforge Bug: #2000654)
354 Fix the blkid regression test suite to tolerate older versions of
355 mkswap that don't support the -U option.
357 A few library routines have been converted to support 64-bit block
358 numbers; in particular, the I/O manager functions, the test_io,
359 inode_io, and unix_io managers have all be converted to support 64-bit
362 Debugfs can now be extended for use by test programs. See
363 lib/ext2fs/extents.c for an example for how it can be used. The test
364 program links against the debugfs object files, and provides
365 additional commands by defining an auxiliary libss command table.
367 The lazy_bg filesystem feature, which was only used by developer's
368 testing, has been removed since it has been largely supplanted by
369 uninit_bg. This also simplifies the code.
372 E2fsprogs 1.40.11 (June 17, 2008)
373 =================================
375 Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
376 percentage of reserved blocks. (Addresses Debian Bug: #452639)
378 Updated Spanish and Catalan translations.
380 Fixed various Debian packaging issues --- see debian/changelog for
381 details. (Addresses Debian Bugs: #483962, #483023)
383 Add detection for ZFS volumes to the libblkid library.
385 Fixed spelling mistakes, typos, and otherwise clarified man pages.
386 (Addresses Debian Bug: #486463)
391 Fix marginal C code in probe_lvm2() function to the blkid library more
392 portable for older compilers.
394 Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
396 Fix ext2fs_swap{16,32,64} functions so they can be used by external
397 applications on big-endian machines. (Addresses Debian Bug: #484879)
400 E2fsprogs 1.40.10 (May 21, 2008)
401 ================================
403 When deciding whether or not to revalidate a blkid cache entry, if the
404 device's mtime is newer than the last time the cached entry was
405 validated, force a revalidation.
407 Fix a potential data corruption bug in e2fsck in the journal replay.
408 The chances of this is happening is extremely remote, especially the
409 default data=ordered or data=writeback modes. However, if a block
410 which has been journalled starts with the first four bytes 0xc03b3998,
411 when e2fsck replays the journal, those four bytes will be replaced
412 with zero's. Fortunately, it is highly, highly unlikely for e2fsck
413 metadata to begin with those fatal 4 byte sequence, and unless
414 data=ordered mode is in use, data blocks are never journaled.
416 Updated German, Dutch, Sweedish, and Vietnamese translations.
421 Fixed various Debian packaging issues --- see debian/changelog for
424 Remove default sizes of types when cross compiling, since autoconf
425 2.50 can figure this out automatically now.
428 E2fsprogs 1.40.9 (April 27, 2008)
429 =================================
431 SuSE's security team audited uuidd and came up with a few minor
432 issues. None of them are serious given that uuidd runs setuid as a
433 unprivileged user which has no special access other than libuuid
434 directory, but it's good to get them fixed.
436 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
437 work correctly with in-inode extended attributes.
439 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
442 Debugfs will avoid using a pager if the standard output is not a tty.
444 Fix debugfs and tune2fs to correctly handle daylight savings time when
445 parsing a time string.
447 Fixed spelling mistakes, typos, and otherwise clarified man pages.
449 Fix fsck completion bars when multiple filesystems were being checked
450 in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
451 #203323, Addresses Sourceforge Bug: #1926023)
453 Fix fsck so that progress information is sent back correctly when
454 multiple filesystems are being check and the output of fsck is being
455 redirected to a file descriptor. Also, include the device name (w/o
456 spaces) in the progress information sent back via a file descriptor.
457 (Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
460 Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
462 If logsave receives a SIGTERM or SIGINT signal, it will now pass that
463 signal to its child process.
465 Fix mke2fs's creation of are resize inode when there is a non-standard
466 s_first_data_block setting.
468 Fix bug in blkid when run by an unprivileged user; most devices were
469 not reported correctly. 9Addresses Launchpad Bug: #220275)
471 Mke2fs will not allow the logically incorect combination of
472 resize_inode and meta_bg, which had previously caused mke2fs to create
475 Fix fsck in German locales so that a 'j' means yes.
476 (Addresses Sourceforge Bug: #1947683)
482 Fixed various Debian packaging issues --- see debian/changelog for
485 Update valgrind options in test_script to work with valgrind 3.2.3
487 Update texinfo.tex to a much newer version from the FSF.
489 Remove bashism for configure script and from the lib/ss Makefile.
490 Addresses Sourceforge Bug: 1921969
492 Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
494 Fix build system so that if texinfo is not installed, it won't print a
495 (harmless) error message.
498 E2fsprogs 1.40.8 (March 13, 2008)
499 =================================
501 Fixed e2image -I so it works on image files which are larger than 2GB.
503 Fixed e2fsck's handling of directory inodes with a corrupt size field. If
504 the size is larger than the number of blocks found in the inode, don't
505 try to allocate extra empty blocks at the end of the directory to make
506 up the difference; there's no point to doing that. In addition, if
507 the size is not a multiple of a blocksize, always fix it.
509 E2fsck handled a pass 2 "should never happen error" by not giving
510 enough information and then core dumping. Unfortunately, it was all
511 too easy to trigger the "should never happen" situation if a
512 directory's inode size was not correct. This has been fixed, but
513 e2fsck has also been taught how to handle this situation more
514 gracefully, by simply removing the inode hash tree information, so
515 that it can be rebuilt again after e2fsck's pass 3. (Addresses
516 Launchpad Bug: #129395)
518 Resize2fs had a bug resizing large inodes with extended attributes
519 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
520 completely on big-endian systems such as PowerPC. The bug should be
521 completely fixed now. Yay for regression test suites. (Addresses Red
522 Hat Bugzilla: #434893)
524 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
525 translations. Many thanks to Philipp Thomas from Novell for stepping
526 up to become the new German translation maintainer! (Addresses Debian
527 Bugs: #302512, #370247, #401092, #412882).
529 When e2fsck is clearing a corrupt inode's HTREE directory information,
530 make it clear that it is just clearing the HTREE information, not the
533 Fixed spelling mistakes, typos, and otherwise clarified man pages.
538 Add new functions, ext2fs_dblist_get_last() and
539 ext2fs_dblist_drop_last(), which allows the caller to examine the last
540 directory block entry added to the list, and to drop if it necessary.
542 Fixed a portability problem in libblkid with DJGPP.
544 Fix an obvious typo in an "internal error" message in e2fsck. Thanks
545 to Philipp Thomas for pointing this out.
547 If the info files are not built, change "make install" so it doesn't
548 fail with an error code.
551 E2fsprogs 1.40.7 (February 28, 2008)
552 ====================================
554 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
555 depreciate the -s option, since it can result in filesystems which
556 e2fsck can't fix easily. There are very good reasons for wanting to
557 disable sparse_super; users who wants to turn off sparse_super can use
558 debugfs. (Addresses Sourceforge Bug: #1840286)
560 Add missing options to mke2fs's usage message. (Addresses Sourceforge
563 Fix bug in resize2fs when large (greater than 128 byte) inodes are
564 moved when a filesystem is shrunk; it was only moving the first 128
565 bytes, so extended attributes were not getting moved. (Addresses Red
566 Hat Bugzilla: #434893)
568 E2fsck now prints an explicit message when the bad block inode is
569 updated, to avoid confusion about why the filesystem was modified.
570 (Addresses Sourceforge Bug: #756460)
572 Allow mke2fs and tune2fs manipulate the large_file feature.
573 Previously we just let the kernel and e2fsck do this automatically,
574 but e2fsck will no longer automatically clear the large_file feature.
575 It still isn't really necessary to worry about this feature flag
576 explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:

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

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

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

711 ===================================
713 Fix a potential overflow big in e2image if the device name is too
716 Mke2fs will now create new filesystems with 256 byte inodes and the
717 ext_attr feature flag by default. This allows for much better future
718 compatibity with ext4 and speeds up extended attributes even on ext3
721 Teach e2fsck to ignore certain "safe" filesystem features which are
722 set automatically by the kernel. Having the kernel set features
723 automagically behind the user's back is a bad idea, and we should try
724 to break the kernel of this habit, especially for the newer ext4
725 feature flags. But for now, we will try to avoid needless full checks
726 which can annoy users who are doing fresh installs.
728 Add support in tune2fs and mke2fs for making a filesystem as being "ok
729 to be used with test kernel code". This will be needed for using test
730 filesystems with the latest ext4 kernel code.
732 Change e2fsck -fD so that it sorts non-htree directories by inode
733 numbers instead of by name, since that optimizes performances much
734 more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
736 If e2image fills the disk, fix it so it exits right away instead of
737 spewing large numbers of error messages.

854 E2fsprogs 1.40.3 (December 5, 2007)
855 ===================================
857 Fix a potential security vulnerability where an untrusted filesystem
858 can be corrupted in such a way that a program using libext2fs will
859 allocate a buffer which is far too small. This can lead to either a
860 crash or potentially a heap-based buffer overflow crash. No known
861 exploits exist, but main concern is where an untrusted user who
862 possesses privileged access in a guest Xen environment could corrupt a
863 filesystem which is then accessed by the pygrub program, running as
864 root in the dom0 host environment, thus allowing the untrusted user to
865 gain privileged access in the host OS. Thanks to the McAfee AVERT
866 Research group for reporting this issue. (Addresses CVE-2007-5497.)
868 Fix hueristics in blkid which could cause a disk without partitions to
869 be incorrectly skipped when a loopback device is present. (Addresses
870 Red Hat Bugzilla #400321.)
872 Fix e2image so that in raw mode it does not create an image file which
873 is one byte too large.
875 Change mke2fs's usage message so it recommends the preferred -E option
876 instead of the deprecated -R option.
878 Enhance the blkid library so it will recognize squashfs filesystems.
879 (Addresses Red Hat Bugzilla #305151.)
881 Enhance e2fsck so it will force the backup superblocks to be backed up
882 if the filesystem is consistent and key constants have been changed
883 (i.e., by an on-line resize) or by e2fsck in the course of its

887 only a single bootable partition will not get missed.
889 E2fsck will no longer mark a filesystem as invalid if it has time
890 errors (i.e., if superblock mount time or last write time is in the
891 future) and the user refuses to fix the problem.
893 The Ubuntu init scripts don't properly set the system time correctly
894 from hardware clock if the hardware clock is configured to tick local
895 time instead of GMT time. Work around this as best as we can by
896 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
897 be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
900 Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
901 Hat Bugzilla #151533.)
903 Fix e2fsck so that if the superblock is corrupt, but still looks
904 vaguely like an ext2/3/4 superblock, that it automatically tries to
905 fall back to the backup superblock, instead of failing with a hard
908 Make the e2fsprogs program more robust so that they will not crash
909 when opening a corrupt filesystem where s_inode_size is zero.
911 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
912 arguments are detected as such and the parse error is reported to the
913 user. (Addresses Debian Bug #435381.)
915 Change e2fsck so it will not complain if a file has blocks reallocated
916 up to the next multiple of a system's page size.
918 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
919 about (valid) filesystems where the inode table extends to the last
920 block of the block group. (Addresses Red Hat Bugzilla #214765.)

923 allocating inode tables for some relatively rare odd disk sizes.

926 Add Catalan translation and update Dutch and Swedish translations

930 still had an issue when trying to figure out whether we need to
931 byte-swap fast symlinks that contained extended attributes.
933 Fixed spelling mistakes, typos, and otherwise clarified man pages.
934 (Addresses SourceForge Bug #1821333.)
940 Fix mke2fs tests to avoid needing any significant ^M (CR) characters
942 Add "make check" to the RPM spec file
944 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
945 works correctly when the prefix is not the root directory.
947 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
948 clena up after themselves by deleting the test.img temporary file
949 after completing the test.
951 Fixed a corner case bug ext2fs_unlink() when trying to delete the
952 first directory entry in a directory block and the last directory
953 entry in the previous directory block is not in use. Fortunately
954 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
955 places where it is extremely unlikely to run into this corner case.
957 Fix missing dependency which would cuase parallel builds to fail.

963 Fix the test_ss.c in lib/ss so it can be used as an example
964 application program for the library as well as a regression test

968 are properly passed back up through the call stack.
970 E2fsprogs 1.40.2 (July 12, 2007)
971 ================================
973 A recent change to e2fsck_add_dir_info() to use tdb files to check
974 filesystems with a very large number of filesystems had a typo which
975 caused us to resize the wrong data structure. This would cause a
976 array overrun leading to malloc pointer corruptions and segfaults.
977 Since we normally can very accurately predict how big the the dirinfo
978 array needs to be, this bug only got triggered on very badly corrupted
981 Fix a bug in e2fsck which caused it to incorrectly salvange
982 directories when the last entry's rec_len is bogusly too big. This
983 resulted in a nonsense filesystem corruption to be reported, and
984 required a second run of e2fsck to fully fix up the directory.

989 Update Turkish, Polish, Dutch, and Vietnamese PO files from the
993 E2fsprogs 1.40.1 (July 7, 2007)
994 ===============================
996 Fix bug which could cause libblkid to loop forever. When revalidating
997 a partition where there is obsolete information in /etc/blkid.tab, we
998 end up freeing a the type tag without clearing dev->bid_type, causing
999 blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
1001 The Turkish translation has a bug in it where it has the translation
1002 of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
1003 @E, recursively, forever, until the stack fills up and e2fsck core
1004 dumps. We fix this by making e2fsck stop @-expansions after a
1005 recursive depth of 10, which is far more than we need.
1006 (Addresses Sourceforge Bug: #1646081)
1008 Compile the default mke2fs.conf into mke2fs program. People are
1009 getting surprised by mke2fs creating filesystems with different
1010 defaults than earlier versions of mke2fs if mke2fs.conf is not
1011 present. So we now create a built in version of mke2fs.conf file
1012 which is used by mke2fs if the /etc/mke2fs.conf is not present.
1013 (Addresses SourceforgeBug: #1745818)
1015 Improve the config/parse_types.sh helper script. Fix a potential
1016 security problem if e2fsprogs is built as root (as Gentoo does!). In
1017 addition fix the script and how it is called from the configure script
1018 so that it does the right thing when cross-compiling. (Fixes Gentoo
1021 Update Vietnamese, French, and Dutch PO files from the Translation
1022 Project. Also created a new e2fsprogs.pot file for translator.
1024 Fix bogus strip permission errors when building under Debian. When
1025 building the e2fsprogs dpkg's, the dh_strip command emits a large
1026 number of error messages caused by the permissions not being right.
1027 So run dh_fixperms before running dh_strip.
1032 Add new function: profile_set_default(). This function sets the value
1033 of the pseudo file "<default>". If the file "<default>" had
1034 previously been passed to profile_init(), then def_string parameter
1035 will be parsed and used as the profile information for the "<default>"
1038 Fix mk_cmds's error reporting so that it is unambiguous that it is the
1039 mk_cmds script which is generating the error. (Obviates Gentoo patch:
1040 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
1042 Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
1043 priority" environment variable that overrides all others, where as
1044 LANG is the lowest priorty environment variable. If LC_ALL is set, it
1045 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
1046 the all the rest are set. This will assure that the locale when
1047 running the test suites is the "C" locale. (Obviates Gentoo patch:

1059 Fix a bug in libblkid which could cause the internal field bid_type to
1060 become corrupted. Fortunately bid_type isn't used much, and bid_label

1074 superblock, so that it won't accidentally find a superblock that was
1075 located in the journal, and then later reject it as being not a valid
1078 Fix e2fsck get_size logic so that it will work with the Linux floppy
1079 driver. The Linux floppy driver is a bit different from the other
1080 block device drivers, in that if the device has been opened with
1081 O_EXCL, it disallows another open(), even if the second open() does
1082 not have the O_EXCL flag. (Addresses Debian Bug: #410569)

1107 Fix e2fsck so that it checks all of the blocks in the journal inode
1108 for validity. The original code only checked the direct blocks to

1126 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
1128 Remove check in e2fsck which requires EA's in inodes to be sorted;
1129 they don't need to be sorted, and e2fsck was previously wrongly
1130 clearing unsorted EA's stored in the inode structure.

1178 artificial test cases, but it will be useful if we ever do the "inodes
1179 in directory" idea for ext4.
1181 Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
1184 Fix resize2fs parsing of size parameter (in sector units). This was
1185 actually a bug in libe2p's parse_num_blocks() function. When handling
1186 the 's' suffix, it was ignoring the blocksize information passed in
1187 from the caller and always interpreting the number in terms of a 1k
1188 blocksize. (Addresses Debian Bug: #408298)
1190 There was a floating point precision error which could cause e2fsck to
1191 loop forever on really big filesystems with a large inode count.
1192 (Addresses Debian Bug: #411838)
1194 Fix memory leak in ext2fs_write_new_inode()
1196 Add support for using a scratch files directory to reduce e2fsck's
1197 emory utilization on really big filesystems. This uses the TDB
1198 library. See the [scratch_files] section of the e2fsck.conf man page
1201 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
1202 platform (Addresses Debian Bug: #397044)
1204 Add explanatory message to badblocks that -n and -w are mutually exclusive
1205 (Addresses Debian Bug: #371869)
1207 Allow debugfs and dumpe2fs to support fs features under development.
1209 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
1210 ext2fs_open() , which allows application to open filesystes with features
1211 which are currently only partially supported by e2fsprogs.
1213 Allow unix_io to support offsets greater than 2G (Addresses
1214 SourceForge Bug: #1547922)
1216 Fixed overflow and signed/unsigned problems caused by the number of
1217 blocks or inodes exceeding 2**31 or being close to 2**32-1.
1219 Add support for unsigned directory hash calculations with hints in the
1220 superblock to fix cross-architectural portability for htree
1221 directories with filenames where the high 8th bit is set. (Addresses
1224 Fix resize2fs so that it gives user-intelligible error messages if the
1225 filesystem or the kernel does not support on-line resizing.
1226 (Addresses Debian Bug: #380548)
1228 Require mke2fs -F -F for really dangerous operations, since -F is
1229 needed for less dangerous operations such as creating filesystems
1230 images in regular files, or creating filesystems on whole block
1231 devices. These relatively innocuous usages should NOT be confused
1232 with running mke2fs on an apparently-mounted or in-use filesystem.
1234 Allow the default inode size to be specified into the mke2fs.conf
1237 Make the smallest default journal size is big enough so that on-line
1238 resizing should always work.
1240 Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
1243 Fix debugfs coredump when lsdel is run without an open filesystem
1244 (Addresses Debian Bug: #378335)
1246 Fix debugfs display bug us that bytes that have the high bit set are
1247 displayed as "ec" instead of "ffffffec".
1249 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
1251 Device mapper scanning wasn't working in the blkid library because the
1252 pathnames had an extra "/dev" when they were being probed.
1254 Add GFS/GFS2 support to the blkid library.
1256 Fix blkid support of empty FAT filesystem labels.
1258 Avoid recursing forever (or for a long time) when the blkid library
1259 searches for a device and there are symlinks to directories in /dev.
1261 Avoid unaligned halfword access in blkid when accessing FAT
1262 superblocks, as this will cause Sparc/Solaris systems to throw a
1265 The latest devmapper libraries requires pthreads, add -lpthreads to
1266 the static link libraries for e2fsck.static if devmapper is enabled.
1267 (Addresses Debian bug: #388718)
1269 Improve the (non-installed, for experts only) findsuper program by
1270 printing the uuid and label from the superblocks, as well as the
1271 starting and ending offsets of the filesystem given the information in
1272 the superblock. Omit by default printing superblocks that are likely
1273 found in located in an ext3 journal unless an explicit -j option is
1276 Updated Spanish, French and Dutch translations and added Catalan
1277 translation. (Addresses Debian bug: #411562)
1279 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
1280 determining a partition's size, since binary searching to determine
1281 the device doesn't work on FreeBSD.
1283 Documentation about UUID's is available in enough places, and it's
1284 awkward to deal with debian-legal's insanities. So I'm caving in the
1285 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
1286 don't have do the dfsg tarball. Also remove the rule that only tried
1287 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
1288 e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
1290 Fix the info-dir line so that the menu name does not contain a .info
1291 prefix. First of all, it's ugly, secondly, it causes the install-info
1292 command to fail to remove the com_err info file from the
1293 /usr/share/info/dir file when the comerr-dev package is removed and
1294 purged. (Addresses Debian Bug: #401711)
1296 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1297 (Addresses Debian Bug: #369761, #373004, #379695)
1299 Fixed various Debian packaging issues --- see debian/changelog for
1300 details. (Addresses Debian Bugs #389554, #390664, #413208, #419605,
1301 #408352, #415560, #399155)
1307 E2fsck now supports the %It expansion when printing a problem report.
1308 It will print the type of the inode in the problem context.
1310 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
1311 (Addresses Sourceforge Bug: #1565561)
1313 Remove unused variables and other lint/gcc -Wall cleanups
1315 Add check to ext2fs_get_device_size() so it will return EFBIG for for
1316 filesystems contained in regular files where the filesystem image size
1317 is returned by stat64().
1319 Set local environment variables to C so mk_cmds and compile_et always
1320 work. (Addresses SourceForge Bug: #1532177)
1322 Added the 64-bit byte swapping function ext2fs_swab64().
1324 Added two new helper functions to prevent 2**31/2**32-1 overflow
1325 problems: ext2fs_div_ceil() and e2p_percent().
1327 Create new ext2fs library inline functions ext2fs_group_first_block()
1328 and ext2fs_group_last_block() in order to calculate the starting and
1329 ending blocks in a block group.
1331 Create the generated files read-only to remind developers not to edit them.
1333 Add support for autoconf 2.60 (with backwards compatibility for older
1334 versions of autoconf).
1336 Added an "make rpm" target to top-level Makefile
1338 Added various FreeBSD portability fixes.
1340 Exclude mercurial files from the RPM build tree to speed up copy/build.
1342 Use root_sysconfdir to define the locations of mke2fs.conf and
1343 e2fsck.conf instead of using a hard-coded /etc pathname.
1345 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
1347 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
1349 If diff -u is supported, use it to report test failures.
1351 Updates/improvements to RPM spec file
1353 Add on-disk format definitions for the following new features:
1354 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
1355 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
1356 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
1358 Add a new make target "checked-failed" in the tests directory which
1359 reruns any failed tests
1361 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
1363 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
1364 pointer dereferences, memory leaks, etc. None were security-criticial
1367 Fix up usage and decrement error messages in the test_icount program
1369 Add debugging code to the com_err library; if the environment variable
1370 COMERR_DEBUG is set to 1, print out debugging messages as error tables
1371 are added and removed from the com_err library. If the
1372 COMERR_DEBUG_FILE environment variable is set (and the process is not
1373 setuid) the debugging messages may be redirected to a file.
1375 Change all of the e2fsprogs programs to use the newer add_error_table()
1376 and remove_error_table() interfaces instead of the much older
1377 initialize_*_error_table() function.
1379 Add TDB support into the ext2fs library. This allows us to have a
1380 guaranteed library we can count on always being present so we can
1381 store data in an on-disk database.
1383 Add support for using TDB to store the icount data, so we don't run out
1384 of memory when checking really large filesystems.
1386 Change the regression test suite so that it skips empty test directories.
1388 Define the l_i_iversion field in ext2_inode. The l_i_version field is
1389 now defined from the old l_i_reserved1 field in the ext2 inode. This
1390 field will be used to store high 32 bits of the 64-bit inode version
1393 Add Makefile production rule for e2fsprogs.spec in case it gets
1396 Add new function profile_get_uint() to allow for a clean way to fetch
1397 unsigned integers from the context.
1399 Add test to make sure the ext2 superblock structure is 1024 bytes.
1401 Fix typo in name of f_dup4 regression test
1403 Add new function blkid_gc_cache() which performs a garbage collection
1404 pass on the /etc/blkid.tab file.
1406 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
1407 general, only e2fsck (after the filesystem is clean), tune2fs, and
1408 resize2fs should change the backup superblocks by default. Most
1409 callers of ext2fs_open() should not be touching any superblock fields
1410 which require the backups to be touched.
1412 Add new function to libext2fs, ext2fs_default_journal_size(), which
1413 returns the default journal size.
1416 E2fsprogs 1.39 (May 29, 2006)
1417 =============================
1419 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
1420 between 2**31 and 2**32 blocks.
1422 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
1423 configure the filesystem features, blocksize, and inode_ratio for
1424 different filesystem types.
1426 Mke2fs will now create filesystems hash trees and on-line resizing
1427 enabled by default, based on the new /etc/mke2fs.conf file.
1429 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
1430 filesystem device node in exclusive mode to prevent accidents by
1431 system administrators. In the case of resize2fs and mke2fs, it will
1432 only use exclusive mode if the filesystem is not mounted.
1434 Fixed a bug in mke2fs which caused it to to fail when creating the
1435 resize inode for large filesystems. (Addresses Debian Bug #346580)
1437 When allocating space for the RAID filesystems with the stride
1438 parameter, mke2fs will now place each portion of the group's inode
1439 table right up after the superblock (if present) in order to minimize
1440 fragmentation of the freespace.
1442 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
1443 efficiently by writing the inode and block bitmaps in one pass, thus
1444 reducing the number of disk seeks required.
1446 Add support for on-line resizing to resize2fs.
1448 Fix blkid library so that logic to determine whether or not a device's
1449 cached information in /etc/blkid.tab needs to be verified or not
1450 doesn't get confused by a system clock which is insane (for example,
1451 if the battery is dead on a Macintosh running PPC Linux. (Addresses
1452 Red Hat Bug: #182188)
1454 The blkid library will now store the UUID of the external journal used
1455 by ext3 filesystems, so that in the future, the userspace mount binary
1456 can use this to find the location of the external journal and pass
1457 this information to the kernel.
1459 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
1460 control how various options should be handled. See the e2fsck.conf
1461 man page for more details. (Addresses Debian Bug: #150295)
1463 E2fsck now prints an explanatory message when delaying a filesystem
1464 check when the system is running on battery. (Addresses Debian Bug:
1467 E2fsck will detect if the superblock's last mount field or last write
1468 field is in the future, and offer to fix if so. (Addresses Debian Bug
1469 #327580) These problems will be fixed automatically in preen mode
1470 since Debian's boot sequence bogusly doesn't set the time correctly
1471 until potentially very late in the bootup process, and this can cause
1472 false positives which will cause users' systems to fail to boot.
1473 (Addresses Debian Bugs #343662 and #343645)
1475 E2fsck now checks to see if the superblock hint for the location of
1476 the external journal is incorrect, and if so, offer to update it.
1477 (Addresses Debian Bug: #355644)
1479 Fix e2fsck from segfaulting on disconnected inodes that contain one or
1480 more extended attributes. (Addresses Debian Bug: #316736, #318463)
1482 E2fsck will stop and print a warning if the user tries running a
1483 read/write badblocks test on a read-only mounted root filesystem.
1485 Fix a memory leak in e2fsck's error paths. (Thanks to Michael
1486 C. Thompson for pointing these out; they were originally found using
1489 When resizing a file containing a filesystem, resize2fs will expand or
1490 truncate a file as necessary. (Addresses Debian Bug: #271607)
1492 Resize2fs will now automatically determine the RAID stride parameter that
1493 had been used to create the filesystem, and use that for newly created
1494 block groups. The RAID stride parameter may also be manually specified
1495 on the command line using the new -S option to resize2fs.
1497 Fix mke2fs so that it correctly creates external journals on
1498 big-endian machines (such as a S/390).
1500 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
1501 fail to print out the journal or hash seed UUID. (Thanks to Guillaume
1502 Chambraud for pointing this out.)
1504 Dumpe2fs will now print the size of the journal (if present).
1506 Fix debugfs's set_inode_field command so it can properly set the frag,
1507 fsize, uid_high, gid_high, and author fields in the inode instead of
1508 silently failing, and so that setting the i_size actually sets i_size
1511 Add a new debugfs command, set_current_time, which sets fs->now so
1512 that regression test suites can repeatedly modify the filesystem's
1515 Fix a bug in debugfs's icheck which would incorrectly report the owner
1516 of an extended attribute block.
1518 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
1519 print a usage message when an illegal option character is given.
1521 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
1522 so it won't core dump. (Addresses SourceForge bug #1424311)
1524 Fix mklost+found so that it creates a full-sized directory on
1525 filesystems with larger block sizes.
1527 Fix a file descriptor leak in blkid library.
1529 Fix a display bug in "badblocks -sv" so that the done message properly
1530 clears the block number at the end of the test. (Addresses Debian Bug
1533 Allow fractional percentages to the -m option in mke2fs and tune2fs
1534 (Addresses Debian Bug: #80205)
1536 Use fstat/fstat64 in getsize.c if the the target is a regular file,
1537 instead of attempting to do a binary search. Fix some fd leaks in
1540 Add support for device mapper library to the blkid library to ensure
1541 that the "best" (i.e., leaf) device is probed by the blkid library.
1543 Fix the blkid library so that it notices when an ext2 filesystem is
1546 Improve the blkid's library VFAT/FAT detection; it now understands
1547 labels stored in the root directory, and is more paranoid about
1548 checking the FAT superblock values.
1550 Fixed a fd leak in the uuid library which was causing problems for the
1551 LVM tools. (Addresses Debian Bug: #345832)
1553 Add support for the reiser4 and software suspend partitions to the
1554 blkid library. Also add support for extract the label from iso9660
1557 Fix a compile_et bug which miscount the number of error messages if
1558 continuations are used in the .et file.
1560 Add extra sanity checks to protect users from unusual cirucmstances
1561 where /etc/mtab may not be sane, by checking to see if the device is
1562 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
1565 Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
1566 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
1568 Fix use-after-free bug in e2fsck when finishing up the use of the
1569 e2fsck context structure.
1571 Fixed spelling mistakes, typos, and otherwise clarified man pages and
1572 documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

1588 Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
1589 Bugs: #360661, #360317)
1591 Fixed the Makefile so that they work correctly on newer versions of
1592 GNU make (i.e., 3.81).
1594 Add valgrind support to the regression test suites, and eliminate
1595 false positives from valgrind.
1597 Add a regression test suite for the blkid library.
1599 Fix a fencepost error in resize2fs caught by valgrind.
1601 Fix compiler warnings about missing memcpy prototypes.
1603 We no longer have the sparc assembly code in the header file any more,
1604 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
1605 break compiles on the sparc architectures when using gcc.
1607 In the libext2fs library, add the new field fs->now which if non-zero
1608 is used instead of the system time when setting various filesystem
1609 fields (last modified time, last write time, etc.)
1611 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
1612 ext2fs.h which is needed since the inline functions use memcpy().
1613 (Addresses Sourceforge Bug #1251062)
1615 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
1616 the build system when building files in the util directory which are
1617 needed during the build process. This avoids potential problems when
1618 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
1619 are not recognized as valid by the host compiler. (Addresses
1620 Sourceforge Bug #1261547)
1622 Clean up the blkid library by making the superblock and generic i/o
1623 functions to be more generic. Clean up interface to the probe
1624 function, and fix memory leak. Finallly, remove an unneeded reference
1625 to probe.h in the lib/blkid/resolve.c
1627 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
1628 of invalid block #'s.
1630 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
1631 indicate that the the function read/writes the memory location.
1633 Fix various gcc -Wall complaints.
1635 Add a dependency to make sure that the subdirectories are created
1636 before creating all of the object files, in order to address parallel
1637 build problem in the library Makefiles. (Addresses Sourceforge Bug:
1640 Add $(LDFLAGS) to the command line argument when generating an ELF or
1641 Solaris shared library, to allow cross-compile and other builds that
1642 might need to specify -L paths to needed libraries. (Addresses
1643 Sourceforge Bug #1261549)
1645 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
1646 intended for testing purposes. It allows an ext2/ext3 developer to
1647 create very large filesystems using sparse files where most of the
1648 block groups are not initialized and so do not require much disk
1649 space. Eventually it could be used as a way of speeding up mke2fs and
1650 e2fsck for large filesystem, but that would be best done by adding an
1651 RO_COMPAT extension to the filesystem to allow the inode table to be
1652 lazily initialized on a per-block basis, instead of being entirely
1653 initialized or entirely unused on a per-blockgroup basis.
1655 Fix backwards compatibility so e2fsprogs will better compile on Linux
1658 Make test scripts more robust against locale-related environment variables
1660 Fix type warning problem with sizeof() in ext2fs_open2().
1662 Fix type warning problem with time_t in debugfs.
1665 E2fsprogs 1.38 (June 30, 2005)
1666 ==============================
1668 Fix blkid's test programs (built with "make check") compile correctly
1669 even without "configure --enable-blkid-debug".
1671 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
1672 type aliasing rules on newer gcc compilers. (Addresses Red Hat
1675 Fix com_err library to make it more compatible with recent changes
1676 made to the com_err library in MIT Kerberos V5 version 1.4.
1677 (Addresses Sourcefroge Bug #1150146)
1679 General cleanup of messages printed by e2fsprogs programs for grammar,
1680 consistency, and to make life easier for translators. Fixed a few
1681 strings containing English that had not been marked as needing
1682 translations. Removed strings that do not need to be translated, to
1683 make life easier for translators.
1685 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
1686 test to see if a device appears to be in use instead of just relying
1687 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
1689 Fix portability problem in the filefrag program affecting platforms
1690 where the size of an integer is smaller than the size of a long.
1691 (Addresses Debian Bug #309655)
1693 Mke2fs will now use a larger journal by default for filesystems
1694 greater than 4GB. (128 MB instead of 32MB).
1696 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
1697 unless forced. This is to avoid signed vs. unsigned kernel bugs in
1698 block numbers that still need to be fixed.
1700 The blkid program has a new option which will more efficiently search
1701 for device when it is known (or expected) that only one matching
1702 device will be found in the system, such as when doing a lookup by
1705 Debian's e2fsprogs-specific initrd fragment will avoid including
1706 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
1707 and LD_LIBRARY_PATH, and filtering out libraries found in
1708 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
1710 Fixed a potential portability issue in the blkid programs for
1711 architectures where the char type is unsigned. (Addresses Sourceforge
1714 Fix a bug in filefrag so that it doesn't falsely count an extra
1715 discontinuity when the first block found is an indirect block.

1730 filesystems. (Addresses Debian Bug: #303509)
1732 If the superblock last mount time indicates that the system clock may
1733 not be accurate, then e2fsck will omit checking inodes' deletion time
1734 field for indications of a potential corrupted orphaned inode list.
1735 (Previously e2fsck only ommited these LOW_DTIME checks when the
1736 superblock's last write time looked insane.)
1738 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
1739 (Addresses Debian bug #302200)
1741 Make the blkid library more paranoid about being run from setgid
1742 programs, and to use __secure_getenv() from libc if it is available.
1744 Fixed spelling mistakes, typos, and otherwise clarified man pages.
1745 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
1746 and Sourceforge Bug: #1189803)
1748 Updated and fixed translations.
1750 Fixed various Debian packaging issues --- see debian/changelog for
1756 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
1757 changed to take an unsigned int for the bit number. Negative bit
1758 numbers were never allowed (and didn't make any sense), so this should
1759 be a safe change. This is needed to allow safe use of block numbers
1760 greater than or equal to 2**31.
1762 The compile_et program will avoid recreating generated foo_err.c and
1763 foo_err.h files if no changes are necessary. The compile_et program
1764 will also atomically replace these files to avoid a potential parallel
1765 build race problem on SMP systems. (Addresses Sourceforge Bug:
1768 Added a new function to the blkid library, blkid_probe_all_new(),
1769 which only probes newly added disk devices, and change
1770 blkid_find_dev_with_tag() to use this function so that when a
1771 requested tag is not found, devices that were previously not checked
1772 are searched before searching all devices in the system.
1774 Added new functions to the blkid library, blkid_dev_set_search() and
1775 blkid_dev_has_tag().
1777 E2fsck's problem strings can now use @m and @n as abbrevations for
1778 "multiply-claimed" and "invalid", respectively.
1780 The e2fsprog.pot file now has an explanation of how the @-expansion
1781 and %-expansion works, and strings in e2fsck/problem.c which contain @
1782 characters now have comments in e2fsprogs.pot with the @-expansion to
1783 make life easier for translators.
1785 Fixed missing return values in the ext2fs library which could cause it
1786 to return random garbage in certain error conditions.
1788 Allow the current time to be overriden via the E2FSCK_TIME environment
1789 variable for use in regression tests.
1791 The test scrpit driver program now exits with a non-zero status if
1792 there any of its test that it ran failed.
1794 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
1797 Fixed "make check" so that it compiles correctly even when e2fsprogs'
1798 header files have not be installed in the system include directories.
1799 (Addresses Sourceforge Bug: #1180572)
1801 Fixed gcc -Wall nits.
1804 E2fsprogs 1.37 (March 21, 2005)
1805 ===============================
1807 Add support for checking the validity of Extended Attributes stored in
1810 Add support for dumping the contents of large inodes to debugfs,
1811 including the extended attributes stored in inodes.
1813 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
1814 when we create a new inode we make sure that the extra information in
1815 the inode (any extra fields in a large inode and any ea-in-inode
1816 information) is initialized correctly. This can take place when
1817 mke2fs creates the root and lost+found directory, when e2fsck creates
1818 a new root inode or a new lost+found directory, and when the user uses
1819 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
1820 create inode could inherit garbage (or old EA information) from a
1821 previously deleted inode.
1823 Fixed a bug in e2fsck so it would notice if a file with an extended
1824 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
1827 Added support to filefrag to detect files which are using the new
1828 experimental file extents format, and use the non-ext2 algorithm in
1829 that case. Fixed a bug to avoid reporting a false discontinuity if
1830 there is one or more unallocated blocks at the beginning of a file.
1832 Duplicated a check for noticing whether or not the number of blocks
1833 (given a certain blocksize) is greater than 2**32 when the
1834 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
1835 allows mke2fs to automatically use a larger blocksize when creating a
1836 filesystem on a very large device when run on systems that do not
1837 support BLKGETSIZE64.
1839 Fix the I18N build which was broken in e2fsprogs 1.36 because the
1840 build system had been switched to treat the .gmo files as shipped
1841 files (for backwards compatibility with systems that have older GNU
1842 I18N tools installed), but the gen_tarball.in script was still
1843 removing the .gmo files from the official source distribution.
1845 Fixed various Debian packaging issues --- see debian/changelog for
1846 details. (Addresses Debian Bugs ##296769, #299341)
1851 Added new functions to the e2p library which convert between a string
1852 and os_type: e2p_os2string() and e2p_string2os(), and used them to
1853 make the generated binaries more compact.
1855 Fixed a compile-time error on Darwin systems.
1857 Cleaned up the lib/ext2fs Makefile slightly.
1860 E2fsprogs 1.36 (February 4, 2005)
1861 =================================
1863 All of the patches that were applied to Fedore Core 3's
1864 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
1865 lot of bug fixes first. Users of Fedora Core 3 are strongly
1866 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
1868 Add support for filesystem with the online resizing via resize inode
1869 feature. Fixed numerous bugs from the Fedora patches. The Fedora
1870 patches also didn't bother to do any consistency checking on the
1871 resize inode, or add any tests to the regression test suite. The "-R
1872 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
1873 being listed in mke2fs's usage message. All of these shortcomings
1874 have been corrected.
1876 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
1877 program. In order to do this, the user must run the commands:
1879 debugfs -w /dev/hdXXX -R "features ^resize_inode"
1880 e2fsck -f /dev/hdXXX
1882 Optionally, the ext2prepare command can be used to re-enable online
1883 resizing after the filesystem has been fixed.
1885 The fsck program will now accept an optional filedescriptor argument
1886 to the -C option. (The Fedora version of this patch would sometimes
1887 cause fsck to ignore a parameter on fsck's command line in some rare
1890 Make sure e2fsprogs doesn't write garbage into the reserved portion of
1893 Make sure resize2fs releases the blocks belonging to the old inode
1894 table blocks when moving the inode table. (Addresses Debian Bug:
1897 Skip the r_resize_inode test if resize2fs is not compiled (due to
1898 configure --disable-resizer)
1900 E2fsck now checks the summary filesystem accounting information, and
1901 if any of the information is obviously wrong, it will force a full
1902 filesystem check. (Addresses Debian Bug #291571)
1904 Fix e2fsck to not complain when the resize_inode feature is enabled,
1905 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
1908 Fix e2fsck to note delete symlinks that contain an extended attribute
1909 after the ext_attr feature flag has been cleared. (Addresses Red Hat
1912 Add new utility program, copy_sparse.c, which is very useful
1913 for dealing with large sparse files (such as e2image files).
1915 Add support for jnl_blocks[] for debugfs's set_super_value.
1917 Fix filefrag so that it works correctly with sparse files.
1919 Filefrag -v will print first and last blocks.
1921 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
1924 Add mke2fs support so that it can support filesystems larger than 4TB
1925 automatically, by retrying with a 4k blocksize if the device size is
1926 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
1929 Change blkid to test for NTFS first because Windows sometimes doesn't
1930 clear enough of the parition to confuse the probing routines into
1931 thinking the old filesystem type is still valid. (Addresses Debian
1934 Add support for swap partition label and uuid's in the blkid library.
1936 Add support to the blkid library to recognize Oracle ASM volumes.
1938 Make blkid -t display all devices that match the specified criteria,
1939 not just the first one, and work more consistently when the blkid
1940 cache file is not available or set to /dev/null. (Addresses Debian
1941 Bug #290530 and #292425)
1943 Badblocks will now correctly display block numbers greater than
1944 999,999,999 in its progress display.
1946 The tune2fs program will not allow the user from setting a ridiculous
1947 number of reserved blocks which would cause e2fsck to assume the
1948 superblock was corrupt. E2fsck's standards for what is a ridiculous
1949 number of reserved block has also been relaxed to 50% of the blocks in
1952 The blkid library will return vfat in preference to msdos, and ext3 in
1953 preference to ext2 (if the journalling flag is set) so that mount will
1954 do the right thing. (Addresses Debian bug #287455)
1956 Mke2fs will now use the -E option for extended options; the old -R
1957 (raid options) option is still accepted for backwards compatibility.
1958 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
1960 Mke2fs will now accept a size in megabytes, gigabytes, and other units
1961 (via "32m" or "4g" on the command line) if the user finds this more
1962 convenient than specifying a block count.
1964 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
1965 cache conherency problem.
1967 Debugfs now supports a new command, set_inode_field, which allows a
1968 user to manually set a specific inode field more conveniently, as well
1969 as set entries in the indirect block map.
1971 Debugfs's set_super_value command has been enhanced so that the user
1972 can set most superblock fields, including the date/time fields and
1973 some of the more newsly added superblock fields.
1975 E2fsprogs programs now accept an offset to be passed to the file
1976 specifiers, via the syntax: "/tmp/test.img?offset=1024".
1978 E2fsprogs programs will now accept blocksizes up to 65536; kernel
1979 support on the x86 doesn't exist for now, but it can be useful on
1980 other architectures with page sizes greater than 4k. There are 2.6
1981 kernel patches out there which enable this, but they are of this
1982 writing still experimental.
1984 The e2image command now takes the -s option which will scramble
1985 directory entries for raw image files.
1987 Fix a file descriptor leak in the filefrag program.
1989 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
1992 Fix bug in debugfs where kill_file would lead to errors when deleting
1993 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
1995 Fix bug in the blkid library when detecting the ocfs1 filesystem
1997 Remove obsolete EVMS 1.x and a.out DLL support.
1999 E2fsck will attempt to recover from a journal containing illegal blocks.
2001 Fixed two potential ordering constraint problems in e2fsck which might
2002 cause the filesystem to be corrupted if e2fsck is interrupted during a
2003 (extremely narrow) race window. Thanks to Junfeng Yang from the
2004 Stanford Metacompilation group for pointing this out.
2006 Fixed bug in e2fsck where it would not accurately detect whether or
2007 not the system is running on adaptor if the ACPI device representing
2008 the AC adapter didn't correspond to the what was used on IBM
2011 Change e2fsck to accept directories greater than 32MB.
2013 Fix e2fsck so that a checkinterval of zero disables a time-based check
2016 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
2017 to the PAGER environment variable. (Addresses Debian Bug #239547)
2019 Tune2fs will not mark rewrite the superblock if the feature bitmasks
2022 The debugfs program will set the filetype information when creating a
2025 Add debugfs -d option to use a separate source of data blocks when
2026 reading from an e2image file.
2028 Add e2image -I option which allows the e2image metadata to be
2029 installed into a filesystem.
2031 Fixed bug in the badblocks program which caused "done" to always
2032 appear in english even when a translation was available. (Addresses
2035 The blkid program has a new option -o which controls the output format
2036 of the blkid program; this is makes blkid more convenient to use in
2039 Fix a minor bug in uuid library, which was not using the full 14 bits
2040 of clock sequence when generating UUID's.
2042 Fix a Y8.8888K problem in the uuid library.
2044 Logsave now creates a new session id for itself to avoid getting
2045 killed by init whan transitioning between init levels.
2047 Change the licensing of the UUID library to be the 3-clause BSD-style
2048 license; this allows Apple to use the uuid library in Darwin.
2050 Add ocfs and ocfs2 probe support into the blkid library.
2052 Fix a memory and file descriptor leak in the blkid library.
2054 The blkid library will revalidate the device if the system time is
2055 earlier than last verification time of the device, since that
2056 indicates that the system time is probably nottrustworthy.
2058 The blkid library will override the default location of the blkid.tab
2059 file by the BLKID_FILE environment variable, if it is available.
2061 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
2063 Add various portability fixes for lame new versions of glibc, Darwin
2064 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
2065 Bugs #239934, #264630, #269044, #255589, #289133)
2067 Add support for Windows 9x/NT under Cygwin.
2069 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
2070 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
2072 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
2074 Update the rpm spec files so that it works better with Fedora core 2
2077 Fixed various Debian packaging issues (see debian/changelog). In
2078 particular, fixed the Debian initrd scripts. (#241183, #248050,
2085 Fixed various gcc -Wall warnings.
2087 The uuid library now has new functions uuid_unparse_upper() and
2088 uuid_unparse_lower() which forces the case of the hex digits to be
2089 upper case, or lower case.
2091 The build process has been speeded up by enhancing the subst program
2092 to update the modtime on the generated files even when the generated
2093 file hasn't changed.
2095 The uuid library now uses C99 stdint.h types instead of custom types.
2097 Updated config.guess and config.sub with newer versions from the FSF.
2099 Removed out of date .cvsignore files from the source distribution.
2101 The ext2fs_unlink() function will return an error if both the name and
2102 inode number are unspecified, to avoid doing something surprising
2103 (such as unconditionally deleting the first directory entry).
2104 Directory entries are now deleted by coalescing them with the previous
2105 directory entry if possible, to avoid directory fragmentation. This
2106 is not an issue with the e2fsprogs suite, but may be a problem for
2107 some of the users of libext2fs, such as e2tools.
2109 Add support for version numbers of the form "1.36-rc1".
2111 Fix build of mke2fs.static.
2113 Add basic ext2fs library support for large (EA in inode) inodes.
2115 The test_io mechanism can now abort after n reads or writes to a
2116 particular block. The block is specified by TEST_IO_BLOCK environment
2117 variable, and the read/write count by the TEST_IO_READ_ABORT and
2118 TEST_IO_WRITE_ABORT environment variables. The block data is now only
2119 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
2121 UUID_DEFINE() in the uuid library now creates a static variable, with
2122 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
2123 be used in header files.
2125 Add support for the install-strip and install-shlibs-strip targets, as
2126 suggested by the GNU coding guielines. "make install" no longer
2127 strips the binaries which are installed.
2129 Remove support for the --enable-old-bitops configure option which was
2130 only for very old sparc systems.
2132 Remove support for --enable-clear-htree; this was only needed during
2133 the early development of the htree patch.
2135 Use Linux-kernel-style makefile output so it is easier to see compiler
2138 Update gettext files to version 0.14.1.
2140 Update to use autoconf 2.5x.
2142 Improved support for compiling e2fsprogs under dietlibc.
2144 Make e2fsprogs portable to Solaris and FreeBSD systems.
2146 Add blkid_verify(), blkid_get_library_version(), and
2147 blkid_parse_version_string() functions to the blkid library.
2149 Add pkg-config files for e2fsprogs's libraries.
2151 Fix "make uninstall" to so that it removes everything that is installed.
2153 Add a configure --enable-maintainer-mode option which enables the
2154 makefile rules to rebuild the configure script from configure.in, and
2155 to reubuild the .gmo files in po directory.
2157 Drop the sparc assembly bitwise operations; it's less efficient
2158 than the GCC 3.4 compile code and triggers compiler warnings on
2159 sparc64. Thanks to Matthias Andree for his analysis and suggestions.

2163 E2fsprogs 1.35 (February 28, 2004)
2164 ==================================
2166 E2fsck has a new -k option, which in conjunction with the -c options,
2167 preserves the existing badblocks list.
2169 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
2171 E2fsprogs will now deal correctly with symlinks that contain
2172 extended attribute information, which can be created using SE Linux.

2175 Remove a double longjump into an invalid stack frame bug in e2fsck.
2176 (This was during an abort sequence, which normally worked on Linux and
2177 caused a core dump on other operating systems.)
2179 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
2180 (the NLS library will replace "" with the .po header information).
2182 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
2183 dump due to a division by zero error. (Addresses Debian bug #207082)
2185 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
2186 when reconnecting a directory requires creating a lost+found
2187 directory. (Addresses Debian bug #219640).
2189 Fixed a bug where e2fsck would bomb out if a journal needed to be
2190 replayed when using an alternate superblock.
2192 E2fsck will give an extra grace period before actually forcing a check
2193 if the laptop is running on battery. The next time fsck runs while
2194 the system is on the AC mains, or after the grace period is exceeded,
2195 the filesystem will be checked. (Addresses Debian bug #205177)
2197 E2fsck will inform the user when there are 5 or fewer mounts before a
2198 filesystem check will be forced. (Addresses Debian bug #157194)
2200 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
2201 We now correctly handle the case where there is an overlap between a
2202 block group descriptor or a superblock and a bad block indirect block.
2203 In the case where the indirect block is corrupted, we now suggest
2206 Fix byte swap bugs in e2fsck that caused the journal backup location
2207 in the superblock and symlinks created by SE Linux to be cleared
2208 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
2210 E2fsck -c now replaces the current list of bad blocks with the ones
2213 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
2214 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
2216 Fix a potential bug in e2fsck which could cause it to core dump when
2217 trying to print the location of the backup superblock.
2219 Protect against a potential core dump in e2fsck when printing a
2220 message about backup superblocks.
2222 Add support for backing up the journal inode location in the
2223 superblock. E2fsck will automatically save the journal information in
2224 the superblock if it is not there already, and will use it if the
2225 journal inode appears to be corrupted. ext2fs_add_journal_inode()
2226 will also save the backup information, so that new filesystems created
2227 by mke2fs and filesystems that have journals added via tune2fs will
2228 also have journal location written to the superblock as well.
2229 Debugfs's logdump command has been enhanced so that it can use the
2230 journal information in the superblock.
2232 E2fsck will now update all superblocks when moving the journal inode.
2234 Shrink the size of the e2fsck executable by moving some initialized
2235 variables to the BSS segment.
2237 E2fsck will avoid printing the ^A and ^B characters which bracket the
2238 progress bar when stdout and stdin are a tty device instead of a pipe
2239 to another program. (Addresses Debian bug #204137)
2241 Debugfs's mkdir command will automatically expand the directory if
2242 necessary. (Addresses Debian Bug: #217892)
2244 Fixed a bug in debugfs so that copying a file from /dev/null uses the
2245 correct mode bits. (Addresses Debian Bug: #217456)
2247 If the environment variables DEBUFS_PAGER and PAGER are not set,
2248 debugfs now searches for the appropriate pager to use, beginning with
2249 /usr/bin/pager, and then falling back to 'more' and 'less'.
2250 (Addresses Debian bug #221977)
2252 Debugfs will now support 2.6 device numbers where the major or minor
2253 number may be larger than 255. (Addresses Sourceforge bug #865289)
2255 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
2257 Chattr now stops processing options when it sees '--'. (Addresses
2260 Fix regression tests so they work correctly when e2fsprogs is compiled
2261 with configure --disable-htree.
2263 Fix bug in uuid library when there is no network card and the library
2264 is generating a time-based uuid. The random MAC address was not
2265 correctly generated to be a multicast address.
2267 Add compile_et extensions from Heimdall that were missed the first time
2270 Fix bug in badblocks when using O_DIRECT; we need to make sure that
2271 we're reading from an offset which is page aligned. For read-only and
2272 read-write tests, we try to recover after an error so that we can
2273 continue reading on page-aligned boundaries. (Addresses Debian Bug

2293 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
2294 Bugzilla Bug #112448)
2296 Centralize code which calculates the location of the superblock
2297 and block group descriptors so that it is in a single library routine.
2299 Added two new functions, ext2fs_file_open2() and
2300 ext2fs_inode_io_intern2() which take a pointer to an inode structure.

2314 **'. The EVMS code uses an ugly union approach since we don't want to
2315 modify the EVMS interfaces.
2317 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
2318 aid build process on systems can use invoke GNU make as "gmake".
2320 Added regression testing for mke2fs.
2322 Fixed gcc -Wall nitpicks.
2324 Fixed various compiler warnings.
2326 Add portability fixes for FreeBSD and for using fsctl under Darwin to
2327 support ext2 ioctl's.
2330 E2fsprogs 1.34 (July 25, 2003)
2331 ===============================
2333 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
2334 a tight loop while waiting for a child fsck to exit in some cases.
2335 This burns CPU times which slows down the low-level filesystem check.
2337 Added code to mke2fs to assure that the default block size for a
2338 filesystem is at least as big as the sector size of the device, if it
2341 Changed mke2fs and resize2fs to round the default size of a filesystem
2342 to be an even multiple of the VM pagesize in order to avoid a Linux
2343 kernel bug introduced when the storage of the buffer cache was moved
2344 into the page cache.
2346 Mke2fs will warn the user when creating a filesystem with journaling
2347 and a blocksize greater than 4096. (Addresses Debian bug #193773)
2349 Fixed a bug in resize2fs which caused it to fail on filesystems with a
2350 non-empty bad block list. Resize2fs now discards any blocks on the
2351 badblock list which are no longer part of the filesystem as the result
2352 of a filesystem shrink. (Note: this means that shrinking and then
2353 enlarging a filesystem is no longer a reversible operation;
2354 information about bad blocks in the part of the filesystem which is to
2355 be chopped off will be lost.)
2357 Changed resize2fs so the user can use prefixes to specify the units of
2358 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
2359 and to make the error and informational messages explicitly display
2360 the blocksize used by the filesystem, in order to avoid confusion.
2361 (Addresses Debian bug: #189814)
2363 Added a new debugfs command, dump_unused, which dumps the contents of
2364 all unused blocks to stdout. (Useful as an emergency try-to-find
2365 deleted data command.)
2367 Added a new debugfs command, imap, which prints the location of a
2368 specified inode in the inode table.
2370 Fixed a bug in the badblocks program which caused it to use one bit of
2371 randomness in its non-destructive read/write test, instead of using a
2372 full 8 bits of randomness.
2374 Added a new option (-t) to badblocks, which allows the user to control
2375 the test pattern(s) used when checking a disk.
2377 The blkid probe function now more correctly detects UDF filesystems.
2379 Fixed a bug in the blkid library which caused it to not update its
2380 cache if a filesystem changes from having a label to not having a
2383 Fixed a bug in the blkid library wihch could avoid an infinite loop
2384 in blkid_find_dev_with_tag() if /proc is not mounted and there the
2385 /etc/blkid.tab file has not yet been created.
2387 Fixed the badblocks program so that the destructive read/write test
2388 honors the -c option, and to use O_DIRECT when possible to avoid
2389 thrashing the system block buffer cache.
2391 Fixed various NLS issues.
2392 - Added Czech and Swedish translations
2393 - Removed testing NYC translation
2394 - Fixed NLS support for message abbrevations in e2fsck
2395 - Remove de-utf.po, since we shouldn't have two versions using different
2397 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
2398 simplify the statistics reporting in e2fsck.
2400 Changed configure.in so that its defaults for *BSD systems no longer
2401 build an fsck wrapper, and not to install in /usr/local by default.
2403 Fixed some minor spelling errors/typo's in e2fsck and the configure
2406 Fixed various Debian packaging issues (see debian/changelog).
2408 Updated and clarified man pages. (Addresses Debian Bug #195616)
2413 Fix gcc -Wall nitpicks.
2415 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
2416 NLS support by default. (Added partial workaround for gettext/Darwin
2417 incompatibility problems.)
2419 Added full MIT KRB5 and Himdall compaibility support to the com_err
2420 library and the compile_et program. (Addresses Debian bug #191900)
2422 Added the blkid_known_fstype() function to the blkid library, which
2423 returns true if it is passed a filesystem type which is recognized by
2424 the blkid probing functions.
2426 Improved the documentation for the blkid library.
2428 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
2429 returns the hardware sector size of a device, if it is available.
2431 Added a dependency in the blkid library's .so file to the uuid
2432 library, since the former uses the latter. (Addresses Debian bug
2435 Added --with-diet-libc and --disable-evms to the configure script.
2437 Fixed a minor memory leak in the badblocks program.
2439 Fixed a portability problem in tune2fs --- not all systems have strptime().
2441 Fixed a portability problem in debugfs with the use of getopt() more
2442 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
2445 Add support Windows support to ext2fs_get_device_size().
2447 Added (normally disabled) debugging code to the Unix I/O manager which
2448 causes it to disable all userspace caching if the NO_IO_CACHE is
2451 Changed the test I/O manager so it can always be linked into e2fsck,
2452 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
2453 configure script. The test I/O manager will only print any debugging
2454 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
2455 variables are set, which specifies which I/O operations are logged and
2456 a block number to watch, respectively. The log messages are sent to
2457 stderr by default, unless a filename is specified via the
2458 TEST_IO_LOGFILE environment variable.
2461 E2fsprogs 1.33 (April 21, 2003)
2462 ===============================
2464 Added a new utility program, logsave, which captures the output of a
2465 command in a log file, even if the containing directory hasn't been
2466 mounted yet (in which case the it saves the output in memory until it
2467 can write out the logfile). This is useful for capturing the
2468 output of fsck during the boot sequence.
2470 Fixed some portability problems that were causing problems under
2471 the Cygwin32 environment.
2473 Mke2fs now interprets a negative number to the -b option as a minimum
2476 Fixed a bug in mke2fs which was incorrectly checking the argument to
2477 the -g option if the default block size was used. (Addresses Debian
2480 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
2481 it can not find filesystem checkers for jfs, reseirfs, and xfs.
2483 E2fsck now updates the global free block and inode counters from the
2484 block group specific counters quietly. This is needed for an
2485 experimental patch which eliminates locking the entire filesystem when
2486 allocating blocks or inodes; if the filesystem is not unmounted
2487 cleanly, the global counts may not be accurate.
2489 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
2490 2.0 is not yet supported; this only pulled in the bug fixes: fixed
2491 possible hangs caused by bugs in calling waitpid, and not setting the
2492 pipe to non-blocking mode; also fixed a file descriptor leak; made
2493 sure all functions call log entry/exit functions.)
2495 Badblocks now flushes its output file as bad blocks are discovered.
2497 The uuid library is now more paranoid about assuming the correctness
2498 of the /dev/random device; it mixes in a stream of bytes from
2499 random/srandom, just in case.
2501 Update Debian files to reflect the fact that I am now the Debian
2502 maintainer of e2fsprogs. Other various Debian-specific packaging
2505 Move the source tarball generation functions from the top-level
2506 makefile to the util/gen-tarball script.
2508 Updated the Turkish .po translation file.
2510 Added Heimdal and MIT krb5 extensions to the com_err library to make
2511 it more compatible with com_err libraries from those distributions.
2513 Changed dumpe2fs to always display the superblock fields relating to
2514 the journalling and/or directory indexing feature even if those
2515 features are not enabled.
2517 Updated and clarify copyright statement vis-a-vis alpha releases of
2520 The ss library will now try to dynamically link to the readline
2521 library and use it if it is present in the system. This means that
2522 the debugfs program now has line editing and history features. The
2523 SS_READLINE_PATH environment variable is used to find a readline or
2524 readline-compatible library.
2526 E2fsck now finds most duplicate filenames (all when rebuilding all
2527 directories via the -D option) and offers to delete or rename
2528 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
2530 Fix bug in e2image. When writing out a raw image file, include data
2531 blocks from symlinks that do not store the symlink within the inode.
2533 Fix bug in resize2fs which incorrectly moved the block and inode
2534 bitmaps for sparse superblock filesystems and incorrectly marked
2535 blocks as in use. (Addresses Debian bug #174766)
2537 Added a new shared library, the blkid library, which efficiently
2538 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
2539 and UUID filesystem specifiers without needing to search all of the
2540 devices in the system. Instead, the device is looked up in a cache
2541 file, and then verified to make sure the blkid cache is correct.
2543 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
2544 the device name, using the blkid library. (Addresses Debian bugs
2547 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
2548 used for spaces in device labels.
2550 Removed 32-bit limitations for debugfs's dump command.
2552 If the user specifies a large number of inodes, Mke2fs will
2553 automatically adjust the number of blocks per group to find a valid
2554 set of filesystem parameters.
2556 Add workaround to detect broken MD devices where when some of the
2557 underlying devices are marked read-only, writes to the MD device are
2558 silently dropped. E2fsck will detect if there is an attempt to run
2559 the journal twice, and abort with an error if this is the case.
2560 (Addresses IBM Bugzilla bug #1226)
2562 E2fsck will print an error if more than one of the -p/-a, -n or -y
2563 options are specified.
2565 E2fsck will fix HTREE corruptions in preen mode, without stopping the
2566 boot process. This is needed because the 2.4 ext2 filesystem
2567 accidentally had the INDEX_FL backwards compatibility code removed.
2569 Mke2fs no longer creates filesystems with the dir_index flag set by
2570 default; the user has to specifically request it.
2572 Update and clarified various man pages. (Addresses Debian bugs
2573 #173612, #175233, #175113, and #170497, #185945, #188318)
2575 Created man page for the mk_cmds program (from the libss library).
2580 Fix various gcc -Wall nits.
2582 Fixed a lot of portability problems that caused e2fsprogs not to build
2583 successfully under Solaris and Apple/Darwin.
2585 Fixed a Makefile dependency to allow building e2fsprogs using parallel
2588 Changes to create a subset distribution which consists only of the
2589 et, ss, uuid, and blkid libraries. The configure script and top-level
2590 makefile were changed to support working with a subset distribution.
2592 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
2593 actually used, and might people who are looking for
2594 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
2596 Updated debian files to fix a number of Lintian warnings.
2598 Updated config.guess and config.sub with newer versions from the FSF.
2600 Removed unnecessary libraries from being linked into the fsck, lsattr,
2601 chattr, and blkid executables.
2603 E2fsprogs 1.32 (Nomvember 9, 2002)
2604 ==================================
2606 Fixed a bug in the Unix I/O routines which caused needless writebacks
2607 of clean blocks from the unix_io cache (they were erroneously marked
2608 as being dirty, so they were getting written back to disk before
2609 getting evicted from the disk cache). This was harmless, but it
2610 significantly slowed down e2fsck.
2612 Made some other minor optimizations to the Unix I/O routines to save a
2613 small amount of CPU time.
2615 Updated internationalization files.
2618 E2fsprogs 1.31 (Nomvember 8, 2002)
2619 ==================================
2621 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
2622 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
2623 handling for child process that die unexpectly. Add a hack to force
2624 mkfs to create filesystems that won't cause problems with hardware
2625 that has 2k or 4k minimum blocksize requirements. Read from child
2626 processes in non-blocking mode, so that the GUI continues to update.
2628 Fix e2fsck so that it returns the appropriate exit code when the root
2629 filesystem has been changed, so that system's rc scripts will be told that
2630 the system needs to be rebooted.
2632 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
2633 was set, some of the descriptor blocks that should have been written
2634 out were getting skipped.
2636 Changed e2fsck to force out changes to the backup copies of the
2637 superblock and block group descriptors when important changes are made
2638 to those data structures.
2640 Fix a bug where e2fsck could erroneously mark a filesystem as being
2641 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
2642 introduced in e2fsprogs 1.28.)
2644 If journal debuging is enabled using --enable-jbd-debug, the debugging
2645 level is now set via the E2FSCK_JBD_DEBUG environment variable.
2647 If byteswapping support is disabled using configure --disable-swapfs,
2648 skip the tests which depend on byte-swapping, so that "make check"
2651 Lshattr will now display the indexed directory flag. Also, some of
2652 the more esoteric compression flags are supressed unless compression
2653 support has been enabled.
2658 E2fsprogs 1.30 (October 31, 2002)
2659 =================================
2661 When resizing a filesystem, and inodes need to moved, resize2fs will
2662 update the inode's ctime field, and the mtime field of the containing
2663 directories, so that incremental backups using dump/restore will work
2666 In order to avoid spurious errors, e2fsck wil check the last
2667 superblock write time to determine whether or not it can safely use
2668 the LOW_DTIME checks to determine if there are inodes on the orphan
2669 inode linked list that had somehow gotten disconnected. (Addresses
2670 Sourceforge bug #620980)
2672 Partition in /proc/partitions that being with the string "lvm" are
2673 considered real partitions even if they do not end with a number.
2675 Fixed a bug in the the uuid generation function, where if /dev/urandom
2676 is not present, but /dev/random is, and there isn't sufficient
2677 entropy, the get_random_byte function could spin a loop forever.
2679 E2fsck, mke2fs, etc. will now reliably notice when image files are
2680 mounted using the loopback interface. (Addresses Sourceforge bug
2683 When flushing buffers (as is done by badblocks, for example) check to
2684 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
2685 FDFLUSH ioctl which causes the MD device driver which causes confusing
2686 syslog messages about obselete ioctl messages. (Addresses Sourceforge
2689 Debugfs's write command now checks to see if the destination filename
2690 exists before creating it. (Addresses Sourceforge bug #478195.)
2692 When installing man pages, search for compressed man pages using all
2693 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
2695 Fixed a bug in fsck where multiple filesystems specified on the
2696 command were not being checked in parallel due to a logic bug
2697 introduced to support the FSCK_MAX_INST environment variable.
2699 We have added a new superblock field, s_mkfs_time, which indicates
2700 when a filesystem was created. It is set via mke2fs, and printed out
2701 by dumpe2fs, but is not actually touched by the kernel.
2703 Dumpe2fs has been made more robust by not aborting if there is an
2704 error reading the block/inode bitmaps; instead it will still print out
2705 the location of the block/inode bitmaps and inode table.
2707 Add support for the an alternative block group descriptor layout which
2708 allows for on-line resizing without needing to prepare the filesystem
2709 in advance. (This is the incomat feature flag meta_bg.)
2711 Add support for storing default mount options in the superblock, so
2712 that the filesystem can be mounted with specific mount options without
2713 needing to specify them on the mount command line or in the /etc/fstab
2716 Add support for a new inode flag, which is to be used for indicating
2717 the top of directory hierarchies for the Orlov block allocator.
2719 Fix e2fsck so that if it creates the lost+found directory, it does so
2720 with the more apporpriate permissions of 0700. Also change
2721 mklost+found so that it also creates the directory 0700.
2723 Fixed format bug in e2fsck if NLS is in use.
2725 Add a German translation for e2fsprogs's NLS support.
2727 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
2728 the beginning of the inode table. This won't matter much, since if
2729 there is a bad block at the beginning of the inode table, the root
2730 directory won't be available. But at least e2fsck won't crash in this
2733 Fixed endian problems in the htree code for e2fsck and debugfs.
2735 When byte-swapping a filesystem on a PPC architecture, byte-swap the
2736 bitmaps since the historical big-endian ext2 variant had byte-swapped
2737 bitmaps, and the ext2fs library assumes this. This fixes the
2738 regression test suite on PPC machines.
2740 Fix e2image so that it handles a bad block in the inode table
2743 E2fsck now uses a more sophisticated algorithm to salvage corrupted
2744 directories that recovers more information in the corrupted directory
2747 E2fsck now performs additional consistency checks on indexed (HTREE)
2750 Fix bug where efsck might get confused about whether a completely
2751 empty directory block is an empty leaf block or an interior htree
2752 node. This could cause e2fsck to get confused into think that a valid
2753 indexed directory was corrupted.
2755 E2fsck no longer creates an empty directory entry at the end of a
2756 directory block when optimizing a directory. This would cause some
2757 earlier versions of the dxdir kernel code to corrupt the directory
2758 when attempting to split a node containing an empty directory entry.
2760 E2fsck could sometimes in rare circumstances leave the indexed flag
2761 set after a small directory was optimized by compressing it instead of
2762 indexing it. (This should never happen in real life, since
2763 directories that small wouldn't have been indexed, but better safe
2766 E2fsck now only updates the master superblock in all cases. This
2767 slightly shortens its run time.
2769 Ext2ed can deal with directory entries of length 0; previously it
2770 would get stuck in an infinite loop.
2772 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
2773 specifiers. (Sourceforge patch #613447)
2775 Badblocks will now work correctly on read-only devices such as
2776 CD-ROM's. (Sourceforge patch #600451)
2778 Updated and clarified man pages. (Addresses Debian bug #167108)
2781 E2fsprogs 1.29 (September 24, 2002)
2782 ===================================
2784 Fixed a bug in e2fsck which could corrupt a directory when optimizing
2785 it (via the -D option) or rebuiliding the hash tree index with a 1 in
2786 512 probability, due to a fence post error.
2788 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
2791 Mke2fs now enables the directory indexing flag by default. (Since
2792 this is a compatible feature flag, it's safe to do so.)
2794 Tune2fs will support setting the directory indexing feature flag. It
2795 will automatically set up the default hash algorithm and hash seed
2796 fields in the superblock.
2798 If the bone-headed user enters the root filesystem twice in
2799 /etc/fstab, the -R option which skips the root filesystem will skip
2800 all of them. (Addresses Debian bug #159423). Note! This is not a
2801 precedent for dealing intelligently with any other kind of doubled
2802 entry in /etc/fstab!
2808 Removed perror declaration in lib/et/internal.h. All modern systems
2809 can be expected to define perror() these days. Besides, the lib/et
2810 code wasn't using perror at all anyway. :-)
2813 E2fsprogs 1.28 (August 31, 2002)
2814 ================================
2816 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
2817 for setting the htree flag is not included yet, although it can be
2818 manually turned on via the debugfs program.
2820 Clarified e2fsck error message which is printed when it cannot find
2821 sufficient contiguous block when relcating filesystem metadata.
2823 Added support for building an EVMS plugin module for ext2/3. This
2824 module is substantially the same as the EVMS module shipping with EVMS
2825 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
2826 for use with EVMS 1.0 (which did not include the ext2 plugin module),
2827 if the configure --enable-old-evms flag is given.
2829 Fsck will search through EVMS volumes when trying to resolve
2830 filesystem specifications such as LABEL=xxx or UUID=xxx.
2832 Added a new utility program, /sbin/findfs, which will return
2833 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
2836 Update and clarified various man pages. (addresses Debian Bug #145044,
2837 #146437, #131350, #151990, #144621, #141938)
2839 If there are no filesystems specified on fsck's command line, fsck now
2840 treat that as if the -As options were given. Previously it would
2841 simply do nothing. (Addresses Debian Bug #153102)
2843 Mke2fs no longer treats a failure to be able to clear the MD signature
2844 at the end of the filesystem as a fatal error. (Addresses Debian Bug
2847 The e2p library functions (which are used by lsattr and chattr) now
2848 double check to make sure the file is a regular file or directory
2849 before attempting to use the ext2 ioctls. Some device drivers
2850 unfortunately respond to the ext2 ioctl's with unknown behaviour.
2851 (Addresses Debian Bug #152029).
2853 The extended attribute handling has been updated to correspond with
2854 the latest V2 bestbits ACL code.
2856 Fixed bug in e2fsck which caused it to not clear the dtime field when
2857 processing truncated inodes on the orphan list. This could cause data
2858 loss(!) if a filesystem is rebooted before a truncate has been
2861 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
2862 algorithms. This makes e2fsck much faster in the case of severely
2863 corrupted filesystems where a large number of blocks are claimed by a
2864 large number of inodes. (Thanks to the 2.5 IDE device driver for
2865 inspiring this work.)
2867 Resize2fs has been significantly sped up when shrinking and expanding
2868 a filesystem by a very small number of blocks (for example, when EVMS
2869 is converting a partition to be an EVMS legacy volume).
2871 Added a new option to e2fsck, -D, which will optimize or compress all
2872 of the directories in the filesystem.
2874 E2fsck now catches SIGINT and SIGTERM to make sure it will can
2875 properly clean up and only exit at safe points. Fsck will pass
2876 SIGINT/SIGTERM to its child processes, and wait until they have all
2877 exited before it exits.
2879 The uuid parsing code in the uuid library now properly complains when
2880 an illegally formated uuid is presented to it. (Addresses Debian bug
2883 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
2884 and 2.4.17, since the workaround can cause problems when using a 2.4
2885 kernel with an old version of glibc built with the 2.2 headers.
2887 Fixed a bug in mke2fs where it wasn't properly clearing the initial
2888 superblock used by other filesystems. (Addresses Debian bug #147256.)
2890 Added support for the synchronous directory feature written by Andrew
2893 The debugfs program can delete directories using the rmdir command.
2895 Add support for 8k and 16k filesystems (for systems with page sizes
2896 that are greater or equal to 8k or 16k, respectively). Note that
2897 these filesystems can not be mounted on x86 systems, or other systems
2898 with only 4k page sizes, due to limitations in the current Linux VM
2901 Resize2fs requires that the filesystem state be valid and have no
2902 errors; otherwise, e2fsck -f must be run first. (Previously it simply
2903 required that the last fsck time be greater than the last mount time.)
2905 Configure now defaults the man pages directory to /usr/share/man on
2908 E2fsck now offers to truncate inodes which contain too many blocks (so
2909 that i_blocks would overflow. Also fixed handling of large sparse
2912 E2fsck now more completely checks for symlink validity, including
2913 requiring NULL termination and length checks.
2915 E2fsck will offer to try forcing a disk write to remap a bad block
2916 after finding a read error when reading a filesystem metadata block.
2918 Fixed a bug in debugfs which caused the -b and -s options to crash
2919 debugfs, as well as breaking the testb, setb, and clearb functions.
2921 Added a bmap command to debugfs which calculates the logical to
2922 physical block mapping for a particular inode.
2924 Fixed a bug in code which checked to see if a device was mounted which
2925 sometimes (rarely) failed in the case of a plain file.
2927 Fixed a bug in resize2fs where when it reported an error, it would
2928 print a message erroneously indicating that the filesystem had been
2929 resized before it aborted.
2931 When resizing a plain file which is smaller than the requested size,
2932 resize2fs will attempt to extended the file so that programs like
2933 e2fsck will not complain that the file is too small.
2935 Resize2fs will print the actual new size of the filesystem when it is
2938 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
2939 information on big-endian systems.
2945 Fixed collisions with C++ reserved words.
2947 Added portability fixes for building e2fsprogs on the HURD and AIX.
2949 Added the ext2ed program for creation of test cases. (ext2ed has many
2950 limitations and bugs which make it unsuitable for production use.)
2952 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
2953 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
2954 name_len field is byte swampped on big-endian machines, since in the
2955 V2 structure, name_len is a char field which is doesn't need to be
2956 byte swapped --- except if an old-style kernel had byte-swapped the
2957 name_len field as part of the V1 structure.
2960 E2fsprogs 1.27 (March 8, 2002)
2961 ==============================
2963 The warning messages for mke2fs now go to standard error.
2965 Fixed to make sure "make check" runs all of the test programs with
2966 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
2968 The mke2fs program checks the boot sector for the BSD disk label, and
2969 avoids erasing it if it is there.
2971 Fixed a bug in e2fsck which caused it to core dump if the journal
2972 inode was missing when it was supposed to be there.
2974 E2fsck now prints ranges in pass 5 when printing deltas for the block
2977 Debugfs's "ls -l" command now will print out the file type information
2978 in the directory entry.
2980 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
2981 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
2983 Debugfs can now examine the experimental directory indexing
2986 Fixed bug in debugfs which caused it to core dump if modify_inode is
2987 called without an open filesystem.
2989 The debugfs lsdel command now runs its output through a pager first.
2991 When installing manual pages, remove the compressed manual pages first.
2993 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
2995 Fix the 2.4 resource limitation workaround introduced in 1.26 which
2996 actually broke things on mips32, sparc32, and Alpha platforms.
2998 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
2999 (which is required by the newer libintl libraries).
3004 Fixed various gcc -Wall complaints.
3006 Fixed a few memory leaks in the e2fsck journaling code, and in the
3007 ismounted code checking for a swap device.
3009 Add new inode I/O abstraction interface which exports an inode as
3012 Exported ext2_file_flush as a public interface.
3014 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
3016 Lots of small random portability fixes to make e2fsprogs build under
3017 AIX --- even without the 5L compatibility toolkit, and even using the
3018 uber-crippled AIX native C compiler.
3021 E2fsprogs 1.26 (February 3, 2002)
3022 =================================
3024 Dumpe2fs will keep going now if the bad block inode can't be read.
3025 (Previously it stopped with a fatal error.)
3027 E2fsck will now give an opportunity to run the journal even if the
3028 recovery flag is not set. This is the default behaviour if e2fsck is
3029 using a backup superblock, since the needs_recovery flag will never be
3030 set in the backup superblock copies.
3032 E2fsck now automatically finds the backup superblock/group descriptors
3033 even when the primary superblock is completely destroyed for 2k and 4k
3034 filesystems. (Previously it just guessed/assumed that we were dealing
3035 with a 1k filesystem in that case, and users had to manually specify
3036 the backup superblock number.)
3038 Fixed a bug in e2fsck where it dereferences a null pointer when there
3039 is a problem opening a filesystem in preen mode.
3041 E2fsck now handles external journals correctly; previously it trashed
3042 the external journal device if the journal needed to be replayed.
3044 Work around ulimit incompatibility problem caused by recent 2.4
3045 kernels; the unix IO module will automatically try to set any resource
3046 limits to be infinite on startup.
3048 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
3049 bitmap if it wasn't present and the blocksize was 2k or 4k.
3050 (Addresses Debian Bug #116975)
3052 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
3053 clearing the new V2 fields if they do not make sense or if the ext3
3054 superblock is version 1 superblock.
3056 E2fsck will automatically relocate the ext3 journal from a visible
3057 file (i.e., /.journal) to an hidden inode if the filesystem has been
3058 opened read/write. This allows the users to add a journal while the
3059 filesystem is mounted, but the next time the system is rebooted, the
3060 journal file will disappear. This avoids problems with backups,
3061 stupid operators with superuser bits, etc.
3063 Fix a bug in fsck where it would not support a filesystem type of
3064 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
3066 Fsck now supports fstab entries of the form "ext3,ext2". It will also
3067 automatically identify reiserfs filesystems.
3069 The number of processes spawned by fsck can now be limited using the
3070 FSCK_MAX_INST environment variable.
3072 Fsck now searchs the LVM proc hierarchy to find logical volumes which
3073 should be searched for UUID and label information.
3075 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
3076 limit if at all possible, when opening a block device. (The filesize
3077 limit shouldn't be applied against writes to a block device.)
3079 In mke2fs and e2fsck, specifying the -c option twice will now do
3080 a read/write test on the disk. Update the man pages to encourage
3081 using the -c option, and to discouraging running badblocks separately,
3082 since users tend to forget to set the blocksize when running
3085 Mke2fs now automatically clears the immutable attribute on a
3086 pre-existing .journal file left over from a previous failed attempt to
3087 add a journal to an alreadyy-mounted filesystem.
3089 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
3092 Mke2fs now creates the lost+found directory with permissions of 0700,
3093 so that files that had previously lived in protected directory are
3094 safe if they get dropped in lost+found and the system administrator
3095 doesn't deal with immediately. (Addresses Debian #bug 118443)
3097 Mke2fs and e2fsck (and all programs that use the
3098 ext2fs_check_if_mounted function) will now properly identify that a
3099 device is mounted, even in cases where devfs has confused things with
3100 multiple devices names with the same identity, or if a dim-witted
3101 system administrator has done something stupid like creating device
3102 file aliases in their home directory. Also now checks for swap devices
3103 by using /proc/swaps. (Addresses Debian bug #106622)
3105 Added a new option (-T) to tune2fs which sets the time a filesystem
3108 Speed up e2image when creating sparse raw image files by optimizing
3109 away excess lseek() system calls.
3111 Fix support of large (> 2GB) files when used as a filesystem in
3112 mke2fs, tune2fs, debugfs, and findsuper.
3114 Debugfs's stat and icheck commands now properly deals with large (>
3117 Debugfs's set_super_value command now prints out the list of valid
3118 superblock fields which can be set using the command.
3120 Debugfs's rm and kill_file command now updates the superblock free block
3121 and inode counts, thus keeping the filesystem consistent.
3123 Debugfs's lsdel command now takes an optional argument which allows
3124 the user to only see the most recently deleted files.
3126 A new command (undel) was added to debugfs which automates
3127 undeleting a deleted inode and linking it back to a directory.
3129 Debugfs's ls command now takes a new option, -d, which lists
3130 deleted directory entries.
3132 Debugfs's testb, freeb, setb, and find_free_block commands now take an
3133 optional count argument.
3135 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
3136 be used to signal that a particular inode should not be eligible for
3137 tail-merging --- this is needed for programs like LILO.
3139 The findsuper (an unreleased, uninstalled utility program) has been
3140 improved to add extra validity checks and to add a progress meter.
3141 (It is still an unsupported program; the officially supported way to
3142 recover from a trashed partition table is to use gpart; findsuper is
3143 for wizards only. :-)
3145 Debugfs was fixed to compile with "configure --disable-swapfs".
3147 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
3149 Added new translation file for Turkish.
3154 Fix general gcc -Wall complaints.
3156 E2fsprogs (mostly) works with the dietlibc.
3158 The programming texinfo file has been expanded to include description
3159 of additional libext2fs functions. (Still not compeltely done, but a
3160 lot of the more important functions have been documented.)
3162 Added a umask structure to struct_ext2_filsys, which currently only
3163 modifies the behaviour of ext2fs_mkdir(), but if we add any file
3164 creation functions to libext2fs, we should also make sure they respect
3167 The build-rpm script was fixed to be a bit more safe.
3169 The tests' Makefile now has a way of automating test case creation
3170 for e2fsck, using "make testnew".
3172 Created a new function, ext2fs_dir_iterate2 which passes more
3173 information to the callback function (identical to the one used by
3174 ext2fs_dblist_dir_iterate). The directory iterator functions take a
3175 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
3176 directory entries. If the directory entry is deleted, the callback
3177 function will be called with the entry paraemter set to
3178 DIRENT_DELETED_FILE.
3180 Added new functions, ext2fs_inode_alloc_stats and
3181 ext2fs_block_alloc_stats, which takes updates block/inode allocation
3182 statistics in the bitmaps, block group descriptors, and superblock
3183 when inodes or blocks are allocated or deallocated.
3186 E2fsprogs 1.25 (September 20, 2001)
3187 ===================================
3189 This is primarily a bug-fix release; no new features were added, but
3190 there are a number of embarassing bug fixes and cleanups applied.
3192 Fix a bug mke2fs which causes stack garbage to be written to disk when
3193 zapping disk sectors. (This bug could cause mke2fs to core dump for
3194 some kernels, I suspect with security enhancement patches.)
3196 Remove unneeded #include of <linux/config.h> which was breaking
3197 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
3199 Updated tune2fs man page to reflect the fact that adding or removing a
3200 journal doesn't require running e2fsck.
3202 Remove use of AC_REQUIRE from autoconf which had been used to prevent
3203 AC_CANONICAL_HOST from being called twice; unfortunately this causes
3204 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
3205 used outside of autoconf macros. Fortunately, it doesn't seem to be
3206 necessary any more, anyway.
3208 E2fsck will now not fall back to an alternate superblock if the user
3209 specifies the superblock location explicitly on the command-line.
3210 This allows easier recovery from a situation where the primary
3211 superblock and block groups are slightly corrupted, but the backup
3212 superblocks are completely broken.
3214 Fix problem which caused compile_et and mk_cmds to blow up if
3215 e2fsprogs was in a directory with a pathname that contained spaces.
3217 We are now more paranoid about checking the entry in /etc/mtab to make
3218 sure the filesystem is really mounted, since some broken distributions
3219 (read: Slackware) don't initialize /etc/mtab before checking non-root
3220 filesystems. (Slackware also doesn't check the root filesystem
3221 separately, and reboot if the root filesystem had changes applied to
3222 it, which is dangerous and broken, but there's nothing I can do about
3225 Make UUID library C++ friendly by adding appropriate extern "C"
3226 declarations and using const in the function declarations.
3228 Fix up the com_err texinfo file so that it can product a valid info
3229 file (previously, it could only be used to generate paper
3230 documentation using texinfo.tex).
3233 E2fsprogs 1.24a (September 2, 2001)
3234 ===================================
3236 Fix brown-paper bug in mke2fs which caused it to segfault when
3237 printing the version string.
3240 E2fsprogs 1.24 (August 30, 2001)
3241 ================================
3243 Revert the BLKGETSIZE64 support, since for some distributions, this
3244 ioctl has been used by an unofficial kernel patch to update the last
3245 sector on the disk, and this was causing disk corruption problems as a
3248 Mke2fs is now more careful about zapping swap space signatures and
3249 other filesystem/raid superblock magic values so that programs like
3250 mount who try to use hueristics to determine the filesystem type of a
3251 partition are less likely to be confused.
3253 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
3254 regular file (since Andreas Dilger's on-line resizing tools will set
3257 Fixed some minor texinfo, man pages nits for spelling errors,
3258 texinfo warnings, etc. (Addresses Debian bug #110621.)
3260 E2fsprogs program no longer print the filesystem version number
3261 (i.e. 0.5b), since it only confuses people and doesn't serve any real
3264 E2fsck will once again compile under libc5, since it will supply its
3265 own version of strnlen if necesssary.
3267 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
3268 when specifying the external journal device. tune2fs will also search
3269 devices looking for the externla journal debice when removing.
3271 E2fsprogs 1.23 (August 15, 2001)
3272 ================================
3274 Add initial support for extended attributes (EA); e2fsck will
3275 correctly handle a filesystem with EA's and check the EA blocks for
3278 E2fsck's symlink sanity checking has been cleaned up. It now checks
3279 the i_size value of fast symlinks, and checks for immutable flags
3280 being set of symlinks, etc.
3282 E2fsck now offers to clear inodes which are special files that have a
3283 non-zero i_blocks or i_size field. (The i_size field check was in the
3284 previous version of the code, but due to a bug it didn't offer to
3285 clear the inode unless i_size and i_size_high were both non-zero.)
3287 E2image can now create "raw" image files, which only contain the
3288 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
3289 debugfs, etc., can be run directly on the raw image file.
3291 Add support for the 64-bit block device patches.
3293 Fixed bugs in creating external journals with a 1k blocksize.
3295 Add initial support for external journals (so long as the external
3296 journal only supports a single filesystem) in e2fsck.
3298 Remove requirement for needing to run fsck on a filesystem after
3299 removing a journal (either internal or external).
3301 The man pages now document how to create and manage external journals.
3303 Speed up the check of an ext3 filesystems by avoiding a needless flush
3304 of all of the superblock and block group descriptors.
3306 Speed up creating an internal journal using tune2fs in the case where
3307 the filesystem has a lot blocks already allocated.
3309 Tune2fs has been fixed to make sure that only error messages go to
3310 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
3312 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
3313 now not set the sparse_super feature. (Addresses Debian bug #108165)
3315 Add support in fsck for the filesystem type "auto".
3317 Fsck -A will not try to interpret device names for filesystems which
3318 have a pass number is 0. (Addresses Debian bug #106696).
3320 Fsck prints a warning message if now valid filesystems are passed to
3321 it. (Addresses Debian Bug #107458.)
3323 E2fsck now gives an explicit warning if there filesystem still has
3324 errors at the end of the run. (Addresses Debian bug #104502)
3326 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
3327 reflects an error. E2fsck will also not run the orphan list if the
3328 filesystem contains errors, since the orphan list might be corrupted.
3330 E2fsck now prints the number of large files when given the -v option.
3332 Fixed minor memory leaks in e2fsck.
3334 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
3337 E2fsprogs 1.22 (June 22, 2001)
3338 ==============================
3340 Fixed a bug in e2fsck's handling of orphan inodes which are special
3341 files (i.e., block/character device files, named FIFO's, etc.).
3343 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
3344 tune2fs to fail at adding a journal to a mounted filesystem.
3346 Fixed a few big-endian bugs in e2fsprogs
3347 * The directory block functions were accidentally reporting
3348 some directories as corrupted when they weren't.
3349 * If e2fsprogs is compiled --disable-swapfs, the C language
3350 equivalents weren't being included for big-endian platforms.
3351 (Fixes Debian bug #101686).
3353 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
3358 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
3359 ioctls, and allow them to be defined for non-i386 platforms.
3361 The uuid.h header file is now protected against multiple inclusions.
3363 E2fsprogs is now being developed using BitKeeper. Changed the test
3364 scripts to deal with BK's stripping CR characgters from text files,
3365 and changed the top-level Makefile.in to avoid including BitKeeper
3366 files when generating the source tarball.
3369 E2fsprogs 1.21 (June 15, 2001)
3370 ==============================
3372 Added new configure flags which allow a subset e2fsprogs to be built;
3373 this is most useful for boot floopies, since the resulting shared
3374 libraries and programs are slimmed down by removing features that
3375 aren't necessary for a boot floppy. The new flags that were added
3376 are: --disable-swapfs, which removes support for byte swapping old
3377 legacy PPC/68k filesystems, --disable-debugfs, which removes support
3378 for debugfs from the libext2fs library, --disable-imager, which
3379 removes support for the e2image program, and --disable-resizer, which
3380 removes support for resize2fs.
3382 E2fsck now prints the number of mounts or days elapsed since the last
3383 check when e2fsck is forced to check an otherwise clean filesystem.
3385 Tune2fs now prints an informative message about how often a filesystem
3386 will be checked when adding a journal to the filesystem, to remind the
3387 user that he/she may want to adjust those parameters using tune2fs
3390 Worked around hurd brain-damage which causes e2fsck to sometimes
3391 believe a filesystem is the root filesystem based on device numbers
3392 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
3395 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
3396 erroneous error with the -F option was specified.
3398 Fixed a ext3 recovery bug in the revoke handling; synchronized with
3401 Fixed two bugs in e2fsck's handling of dup block handling, dealing
3402 with relatively uncommon edge cases: a directory with an indirect
3403 block which is claimed by another file, and when the last inode in the
3404 filesystem has blocks claimed by another file.
3406 E2fsck now checks to see if the i_size field of a fast symlink is too
3407 big, and offers to clear the symlink if so.
3409 E2fsck now checks to see if i_size_high of special files is non-zero,
3410 and offers to clear i_size_high.
3412 Fix e2fsck's handling of incompatible journal flags so that the user
3413 has chance to abort, and then has the option to clear out the journal
3414 entirely. (Addresses Debian bug #98527.)
3416 Fixed a bug in fsck which could cause it to core dump if a mix of
3417 standard and non-standard device names are used in /etc/fstab.
3418 (Debian bug #100559)
3420 Fixed a bug in debugfs which caused read errors when copying a file to
3423 The debugfs set_super_value command can now modify the s_lastcheck field.
3425 Fixed a bug in lsattr and chattr which was accidentally introduced in
3426 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
3427 directories correctly because the change modified the layout of struct
3428 dirent to be incompatible with the libe2p shared library.
3430 Cleaned up the mke2fs manual page and included a discussion about why
3431 it's good to periodically check the filesystem even when journaling is
3437 Fix general gcc -Wall complaints.
3439 The types needed by the ext2 header files are now provided by
3440 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
3442 Integers are now preferred to longs when trying to find a 32-bit type
3443 in ext2_types.h. Also, if linux/types.h has already been defined,
3444 don't try to redefine the types.
3446 Fixed make depend script so that it automatically corrects the
3447 pathname cleanups performed by make -M, so I don't have to fix them up
3450 Fixed the d_loaddump test case to be more robust, and not depend on
3453 Removed debugfs's dependence on pread(), which was accidentally
3454 intrudced in e2fsprogs 1.20
3456 Fixed a performance bug in the libext2fs's icount routine; the size
3457 estimate of the icount array was incorrectly being calculated.
3459 Removed use of the badblocks compatibility functions in the e2fsprogs
3462 Added paranoia code which protects against strange cases where /etc
3463 isn't on the root filesystem, or if /etc/mtab doesn't exist.
3465 The header file ext2_types.h is now installed.
3467 Autoconf is used to determine when we are on big-endian machines,
3468 instead of doing run-time tests, to save a few bytes of code.
3470 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
3471 functions are no longer inline functions, which saves space and
3472 doesn't really cost any real performance.
3474 The ext2fs library no longer depends on the e2p library. (What need
3475 there was of it --- namely, fsetflags, was coded in-line).
3477 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
3478 when the user is stupid and tries compiling the package using "make
3481 Miscellaneous code cleanups:
3482 * Added missing files from Makefile.in's SRCS file, so that
3483 their dependencies would be properly calculated.
3484 * Removed redundant code
3485 * Fixed comments in code
3486 * Removed no-longer unneeded argsused #pragma.
3489 E2fsprogs 1.20 (May 20, 2001)
3490 =============================
3492 Add support for replaying the ext3 journal purely in user mode,
3493 including handling the orphaned inode list. Used code contributed by
3494 Andreas Dilger, with bug fixes and the orphaned inode handling done
3497 The mke2fs and tune2fs programs can create or modify a filesystem to
3498 include an ext3 journal. Tune2fs also can be used to remove an ext3
3499 journal from a filesystem.
3501 E2fsck will now check for the existence of a linked list of orphan
3502 inodes in the superblock, and clear those inodes before starting the
3503 rest of the filesystem check (but after the journal playback).
3505 E2fsck now validates the file descriptor passed to the -C option,
3506 which saves against the completion bar getting written to an
3507 unexpected location, such as the disk being checked. (Debian
3508 bug/wishlist #55220)
3510 E2fsck will now bump the filesystem revision number from zero to one
3511 if any of the compatibility bits are set.
3513 Fixed a bug where a badly corrupted directory on a big endian system
3514 could cause e2fsck to die with a bus error. The
3515 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
3516 the ext2 library now does alignment sanity checks on the rec_len field
3517 of the directory entry before using it.
3519 The ext2 library has been enhanced to make tune2fs safe to run on
3520 mounted filesystems. (Users could usually get away with using tune2fs
3521 on mounted filesystems before, but with the advent of ext3 and
3522 journaling, it became important to make tune2fs was *really* safe for
3523 use even when the filesystem being modified is mounted.) E2label is
3524 now implemented by tune2fs using an argv[0] dispatch, so that e2label
3525 is also now safe for use on mounted filesystems.
3527 Added a new program, e2image, which creates a backup of critical ext2
3528 filesystem data structures. The generated image file can be examined
3529 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
3530 the image file to help recover very badly damaged filesystems.
3532 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
3533 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
3534 large file when deciding whether or not the filesystem has large files.
3536 Fixed lsattr and chattr so that they work correctly on large files.
3537 (Fixes Debian bug #72690.)
3539 Removed limitation in get_device_size() which imposed a one terrabyte
3540 filesystem limitation. (Most 2.2 kernels still have a signed int
3541 problem which cause 1 TB block device limitation. Fortunately, the
3542 kernel patches to fix this are much easier than fixing the 2TB
3543 limitation in the kernel. :-)
3545 A max_mount_count of zero is now treated as if no mount count were
3546 set. (Previously, no mount count was indicated by using -1, and a
3547 mount count of zero caused e2fsck to always be run.)
3549 Mke2fs supports two new filesystem types largefile and largefile4.
3551 Mke2fs now adds some randomness in s_max_mount_count so that multiple
3552 filesystems won't be all checked at the same time under normal
3555 Fixed bug in the progress bar printing code which could cause e2fsck
3556 to core dump on an illegal filesystem.
3558 Fixed bug in fsck which could allow more than one instance of e2fsck
3559 to be printing a progress bar. (Debian bug #65267)
3561 Fsck using a UUID or a LABEL specifier will work even if devfs is
3562 compiled into the kernel and not mounted. If the pathnames in
3563 /proc/partitions are incorrect, fsck will search /dev for the correct
3564 device (using the new ext2fs_find_block_device library function).
3565 Fsck now also checks the RAID devices first so that they are properly
3566 found when they are in use. Support has also been added to support
3567 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
3569 Fixed a bug in fsck which caused it not deal properly with 16
3570 byte long filesystem labels.
3572 Fsck's -t option has been made a lot more flexible. The semantics for
3573 what happens if a comma-separated list to fsck has been regularized,
3574 and it is now possible to filter what filesystems will get checked
3575 based what is in the filesystem's fstab entry's option field. (Debian
3578 The dumpe2fs program can now print out the group description
3579 information in hex, and also prints the location of the superblock and
3580 block group descriptor for those block groups that have them.
3582 Mke2fs now clears the ext2 superblock before it starts creating a
3583 filesystem, so that the superblock magic number is only written if the
3584 filesystem creation process successfully completes.
3586 The debugfs program's stat command now pretty-prints the blocks used
3587 by an inode so that it's more compact and informative.
3589 The debugfs stats command now uses the same libe2p code (which is used
3590 by dumpe2fs) to print the superblock header information. This is more
3591 complete, and it avoids a bit of code duplication.
3593 Added a new debugfs command, set_super_value (ssv) which allows the
3594 user to set arbitrary superblock fields.
3596 Debugfs was extended to support inode numbers in hex (by prefixing
3597 them with 0x), and so that modify_inode can set the inode generation
3598 number. Also, there is now a new function command called logdump
3599 which will dump an ext3 journal.
3601 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
3604 Debugfs's dump command now stops immediately upon reporting a disk
3605 read error. (Fixed a bug in ext2fs_file_read library routine which
3606 caused debugfs not to stop.) (Debian bug #79163)
3608 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
3609 checked before /etc/mtab is used, since /proc/mounts is more likely to
3612 Added portability fixes for Solaris and Linux/ia64.
3614 Various manual pages were clarified and cleaned up. (Fixed debian
3615 bugs #63442, #67446, and #87216)
3621 The e2fsck message printer now supports %Iu and %Ig, which will print
3622 out the inode's user and group owners, respectively.
3624 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
3625 that no longer dependent on the system having the correct version of
3626 the kernel header files.
3628 Added a new function to libext2, ext2fs_find_block_device(), which
3629 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
3630 device given its device number.
3632 Added a new function to libext2, ext2fs_sync_device, which centralizes
3633 all of the places which might try to use the BLKFLSBUF or FDFLUSH
3634 ioctls (and usually failing to define them since the system header
3635 files don't usually do this for us, and we're trying to avoid usage of
3636 kernel include files now).
3638 Added new utility programs in tests/progs: random_exercise and
3639 hold_inode. They aren't built by default; they're useful for
3640 exercising ext3 filesystem code.
3642 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
3643 the filesystem close functions to only update the superblock, and to
3644 not touch the block group descriptors. Needed by tune2fs when
3645 modifying a mounted filesystem.
3647 Got rid of struct ext2fs_sb and replaced it with the standard struct
3648 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
3649 source (but not binary) compatibility of some users of the ext2
3650 library. Those applications should just simply do a global search and
3651 replace of struct ext2fs_sb with struct ext2_super_block, and include
3652 the new header file <ext2fs/ext2_fs.h> which defines it.
3654 The ino_t type has been renamed ext2_ino_t to protect applications
3655 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
3656 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
3657 unexpected ABI change.
3659 The Makefiles have been reworked so that "make check" can be run from
3660 the top-level Makefile.
3662 Fix general gcc -Wall complaints and removed dead code.
3664 Remove use of NOARGS, because we assume everyone does ANSI C these
3667 Added build-rpm script from sct.
3669 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
3672 New function ext2fs_flush_icache which must be called if the
3673 application program modifies the inode table blocks without going
3674 through ext2fs_write_inode() interface.
3676 New ext2fs_check_mount_point() function, which will return the mount
3677 point of a device if mounted.
3679 The io_channel abstraction now has an optional interface,
3680 io_channel_write_range, which allows specific byte ranges to be
3683 The unix_io IO channel now supports write-through caching, so that
3684 journal creation is more efficient.
3686 Added x86 assembly language routines to support byte swapping, to
3687 reduce executable size.
3689 Fixed bug in the utility program subst so that it's possible to
3690 replace a substitution variable with a zero-length string.
3692 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
3693 slipped into some of the problem number.
3695 E2fsprogs 1.19 (July 13, 2000)
3696 ==============================
3698 Release the resize2fs program since the timeout before it could
3699 be released under the GPL has finally expired.
3701 Add experimental support needed for the ext2 compression patches.
3702 This requires compiling e2fsprogs with the --enable-compression flag
3703 to the configure script.
3705 Added ext3 journalling support. E2fsck will run the journal (if
3706 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
3707 installed as a symlink to e2fsck. Fsck has been taught about ext3,
3708 and treats it the same as ext2 in terms of the progress bar logic.
3709 Dumpe2fs will display the superblock journaling information if the
3710 filesystem has a journal. The ext2 library will now permit opening an
3711 ext3 filesystem with the recovery flag set. This is necessary for
3712 on-line dump's to work correctly, but there may be issues with this
3713 working well since ext3 is much less agressive about syncing blocks to
3714 the filesystem, since they're safe on the journal.
3716 Tune2fs and e2fsck have been changed to allow the mount_count check to
3717 be disabled by setting max_mount_count to -1. (This was already
3718 supported by the kernel.)
3720 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
3721 are used for ext3 as well.
3723 Added internationalization support for e2fsprogs; must be enabled
3724 by passing --enable-nls to configure.
3726 Always use the provided ext2fs header files to insulate ourselves from
3727 kernel version changes. Which include files are used by e2fsprogs
3728 have also been cleaned up to improve portability.
3730 Limit the number of times that e2fsck updates the progress bar so that
3731 people who are booting using a 9600 baud console don't get swampped by
3734 Improved the loop detection algorithm in e2sck's pass #3 so that it is
3735 much, much faster for large filesystems with a large number of
3738 The memory footprint for e2fsck is now slightly smaller than before.
3740 E2fsck now checks if special devices have a non-zero size, and offers
3741 to clear the size field if it finds such an inode.
3743 E2fsck now checks if special devices have the append-only flag set,
3744 and offers to clear the inode.
3746 E2fsck now properly handles some "should never fail" cases during a
3747 bitmap copy in pass5.
3749 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
3751 E2fsck now calculates the correct location of the backup superblock in
3752 the case of filesystem blocksizes > 1k.
3754 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
3755 which normally didn't cause problems under most filesystem parameters,
3756 but could cause a valid superblock to be rejected in extreme cases.
3757 Other checks for validating superblock values were made more
3760 Added non-destructive write testing to the badblocks program, courtesy
3761 of David Beattie. The badblocks also now has an option to input the
3762 current set of bad blocks, so that known bad blocks are skipped to
3763 speed up the badblocks test. There is also a persistent rescan
3764 feature which causes badblocks to run until it has completed some
3765 number of passes without discovering any new bad blocks.
3767 Badblocks now checks to see if the device is mounted and refuses to do
3768 the tests involving writing to the device if it is mounted. Also,
3769 badblocks now allows the number of blocks to be checked to be
3770 defaulted to the size of the partition.
3772 Fixed a bug in fsck which didn't allow non-root users to be able to
3773 check filesystems if there were any LABEL= or UUID= entries in
3776 The Hurd doesn't support the filetype filesystem feature. The mke2fs
3777 program now makes sure that for the Hurd, the filestype feature is
3778 turned off. E2fsck will check to see if the filetype feature is
3779 turned on for Hurd filesystems, and offer to turn off the feature.
3781 Mke2fs now has a safety check to make sure the number of blocks do not
3782 exceed 32 bits even on a 64 bit platform.
3784 Really fixed a bug in fsck to allow "fsck -As" to run interactive
3785 fsck's. (For those people who like to do interactive fsck's in the
3788 Debugfs has a few new features: the rdump command, which will do a
3789 recursive dump of a directory and all of its contents, and the lcd
3790 command which does a local chdir (much like the ftp command of the
3791 same name). In addition, the debugfs program and the open_filesystem
3792 command now takes three new options: -b and -s, which allows the
3793 blocksize and superblock location to be specified, and the -c option
3794 which is used in catastrophic situations where the block group
3795 descriptors are corrupt. If the -c option is specified, debugfs will
3796 skip trying to read in the block and inode bitmaps.
3798 Debufs's lsdel command was fixed to handle bad blocks in the inode
3801 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
3804 General improvements in error messages
3806 - Mke2fs prints a sane error message if the partition size is zero
3807 (usually because the partition table wasn't reread by the
3808 kernel due to the partition being busy), instead of "invalid
3809 argument passed to ext2 library while initializing superblock".
3811 - Fsck now prints more self-explanatory message if an invalid UUID=
3812 or LABEL= specification is passed to it.
3814 UUID library changed to use the LGPL.
3816 Fixed a bug in the UUID library where very rapid calls to the
3817 time-based UUID generator could cause duplicate UUID's to be returned.
3818 This was not a problem for e2fsprogs, but it could be a problem for
3819 other users of the library.
3821 Make the UUID library more robust in the face of missing or an
3822 improper /dev/urandom or /dev/random files.
3824 Added some random portability fixes for Solaris.
3826 Some minor man page updates.
3828 Fixed a memory leak in the ss library.
3834 We now try to use lseek64 and open64 from the LFS if possible.
3836 The 3rd parameter in e2p's print_flags is now a flags word, instead of
3839 The mark and unmark bitmap functions now return the previous state of
3840 the bit that was being changed, which is useful for some speed
3843 The following functions have been added to enhance the badblocks list
3844 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
3845 ext2fs_badblocks_equal.
3847 The ext2 header files now have the latest journalling fields to the
3850 The ext2fs_mkdir function in libext2fs now properly backs out of error
3851 conditions robustly.
3853 Cleaned up makefiles:
3854 - to cleanly compile with the -j flag.
3855 - so distclean removes all generated files.
3856 - so in case of an error while installing header files, the make aborts.
3858 Fix test_script so that it works correctly when compiling in the
3861 The random UUID generation routine has been made slightly better in
3862 the case where /dev/random doesn't exist. (Use of randomly-based UUID
3863 is still not recommended if /dev/random doesn't exist, however; it's
3864 better to use the time/ethernet MAC address UUID in this case.)
3866 Clean up the build process so it's more friendly in case of missing
3869 The ext2fs header file can now be #include'd into C++ programs.
3871 The e2p.h header file is now installed.
3873 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
3877 E2fsprogs 1.18 (November 10, 1999)
3878 ==================================
3880 Fix a core dumping bug in e2fsck if an imagic inode is present or
3881 (more rarely) if the filesystem is badly corrupted enough that e2fsck
3882 has to restart pass 1 processing. E2fsck now closes the filesystem
3883 before freeing a large number of its data structures, so in the case
3884 of future memory faults, at least the fixed filesystem will be fully
3887 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
3888 imagic inode, it will offer to clear the imagic flag.
3890 E2fsck will now offer to clear the immutable flag on special files
3891 (device/socket/fifos) when running it in non-preen mode.
3893 E2fsck will now set the filetype when creating /lost+found, and when
3894 connected orphaned inodes to /lost+found.
3896 Debugfs's ncheck and icheck commands now handles the case where there
3897 are bad blocks in the inode table without bombing out.
3899 The badblocks list processing code has been made more efficiently for
3900 appending a large number of (ordered) badblocks to the badblocks list.
3902 Some minor man page updates.
3904 Fsck now allows interactive e2fsck's when using fsck -As (not a common
3905 mode, but some people like to do this in boot scripts for silly reasons).
3910 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
3911 with the problem code convention.
3913 The badblocks list regression test program has been updated to work
3914 with previously made API name changes.
3916 The ext2fs_free() command now uses the new badblocks API to avoid
3917 using the compatibility layer.
3919 Added new regression test cases; the run_e2fsck test script now
3920 supports the ability for a test case to run a prepratory command
3921 before running e2fsck.
3923 E2fsprogs 1.17 (October 26, 1999)
3924 =================================
3926 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
3929 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
3930 thus potentially causing problems if a binary UUID contained a NULL
3933 E2fsck now uses stricter checks for directory entries in pass 2:
3934 zero-length filenames are not allowed; neither are 8 byte long
3937 The debugfs "dirty" command now clears the filesystem valid bit.
3938 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
3939 bit in the in-core superblock image. The new functionality is more
3940 what the user expects, and is more useful.)
3942 Added a debugging hook to test parallel fsck; if the environment
3943 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
3944 will be checked in parallel when they normally would not be.
3949 Fixed some #ifdef's for compilation under the Hurd OS.
3951 Fixed minor W2K compatibility problems.
3953 Fixed some miscellaneous GCC warnings.
3956 E2fsprogs 1.16 (October 22, 1999)
3957 =================================
3959 Fixed a race condition bug in fsck; when printing a progress bar, if
3960 checking multiple filesystems in parallel, it was possible for fsck to
3961 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
3962 handler, which would cause it to terminate with a signal 10.
3964 E2fsck now properly handles filesystems that have the
3965 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
3966 filesystem into using or not using FILETYPE feature.
3968 E2fsck now properly handles filesystems that have the IMAGIC feature
3969 turned on (this is used on Linux AFS servers).
3971 The mke2fs program now creates filesystems that have the filetype and
3972 sparse_superblock features enabled by default, unless it is run on a
3973 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
3974 so there is now a new flag -O which allows the user to specify with
3975 which features she would like to create the filesystem; "mke2fs -O
3976 none" will create a filesystsem compatible with 2.0 kernels.
3978 The tune2fs program now has a -O option which allows the user to set
3979 and reset "safe" filesystem features. Currently, the only ones which
3980 allows to be modified are the filetype and sparse_superblock features.
3981 Note setting or clearing either feature will require running e2fsck on
3982 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
3983 requires that there is enough free space on the filesystem for the
3984 extra superblocks which will be created by e2fsck.)
3986 Debugfs can now set and print filesystem features in the superblock
3987 using the "features" command. Dumpe2fs will print out the complete
3988 set of features when listing the superblock.
3990 Dumpe2fs has new options -f (force) and -h (header-only).
3992 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
3993 message to come up. This could happen when decrementing or
3994 incrementing a link count could result in an overflow.
3996 Fixed a bug in e2fsck where the block count on the lost+found
3997 directory would not be properly incremented when the directory was
3998 expanded to the point where an indirect block needed to be allocated.
4000 E2fsck now makes some additional sanity checks on the superblock to
4001 avoid crashing or giving a memory allocation error if some of the
4002 values in the superblock are unresonable (but the superblock otherwise
4005 Fixed a bug in e2fsck where a very badly corrupted filesystem might
4006 require two passes to completely fix the filesystem. This happened if
4007 an inode claimed blocks that was part of the filesystem metadata
4008 (typically, when garbage was written into an inode table or indirect
4009 block, since this kind of filesystem corruption normally doesn't
4012 On the Alpha, glibc declares st_flags although it isn't actually used;
4013 the configure script was improved to detect this case so that
4014 e2fsprogs can avoid using the non-functional stat field.
4016 The manual pages were updated to use a more consistent formatting
4017 style consistent with standard Unix man pages. Mke2fs's man page
4018 added documentation for a few previously undocumented options.
4020 Fixed minor display bugs in tune2fs and mke2fs.
4025 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
4027 Added features to parse and print feature strings into the e2p library.
4028 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
4030 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
4031 whose directory entries contain proper filetype information if the
4032 filesystem supports it.
4034 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
4035 the directory entry filetype information. This is used to set the
4036 directory entry filetype information if the filesystem supports it.
4038 Fixed a bug in ext2fs_expand_dir() where the block count in a
4039 directory's inode would not be properly incremented when the directory
4040 was expanded to the point where an indirect block needed to be
4044 E2fsprogs 1.15 (July 18, 1999)
4045 ==============================
4047 Add configuration checks so that e2fsprogs will compile cleanly on
4048 Linux 2.3 kernels that have renamed i_version to i_generation.
4050 E2fsck now prints a progress/completion bar (and not just a simple
4051 spinner) if the -C0 option is requested or if it receives a SIGUSR1
4052 signal. Fsck will automatically manage the (potentially muliple)
4053 e2fsck processes to print completion bars if it is given a -C option,
4054 with the right thing happening if multiple filesystems are being
4055 checked in parallel.
4057 Mke2fs now has better automatic hueristics to determine the filesystem
4058 parameters to be used for a particular filesystem. Added a new option
4059 -T which allows the user to specify how the filesystem is to be used,
4060 which helps mke2fs do a better job selecting the filesystem parameters.
4062 Mke2fs now creates revision 1 filesystems by default, and with the
4063 sparse superblock feature enabled. The sparse superblock feature is
4064 not understood by Linux 2.0 kernels, so they will only allow read-only
4065 mounts of filesystems with this sparse superblocks.
4067 Fix bug where if /dev/null couldn't be opened (should never happen),
4068 e2fsck would hang in a tight loop.
4070 Make e2fsck handle the case where /lost+found isn't a directory.
4072 E2fsck now uses mallinfo if it exists to get accurate statistics about
4075 Fix bug in e2fsck where it wouldn't check to see if a disconnected
4076 inode had any problems before connecting it to /lost+found.
4078 Add check to e2fsck so it makes sure that total number of inodes in
4079 the filesystem is a sane number.
4081 Fix fencepost error when clearing an the end of the block bitmap which
4082 caused the last block in the bitmap not to get cleared.
4084 Cleaned up a number of messages in e2fsck:
4085 * The message "Group's #'s copy of the group descriptor..."
4086 was fixed so that the correct number would be displayed.
4087 * Added missing space in the "disk write-protected" error messsage
4088 * Cleaned up the error message printed when a non-interactive
4089 e2fsck needs to abort a check because the filesystem
4090 appears to be mounted.
4092 Added a new command-line utility, uuidgen, which will create and print
4095 Make debugfs's icheck command more robust by checking to make sure an
4096 inode has valid blocks before interarting over the inode's blocks.
4098 UUID generation now uses a random-based scheme whenever possible to
4099 prevent potential privacy problems.
4101 Man pages for all of the UUID functions in the lirbary were added.
4103 Fixed bug in fsck so it won't coredump if a filesystem not in
4104 /etc/fstab is given to it.
4106 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
4107 that most of the other mount utilities understands.
4109 Mke2fs will make a filesystem even if it appears mounted if the force
4112 Dumpe2fs has new command-line options which allow a filesystem expert
4113 to specify the superblock and blocksize when opening a filesystem.
4114 This is mainly useful when examining the remains of a toasted
4117 The badblocks program has been updated to display correctly on disks
4118 with large block numbers.
4120 The badblocks program no longer gives spurious errors when errors
4121 occur on non-block boundaries, which is common if the blocksize is
4124 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
4125 MKE2FS_SYNC environment variable is set. This is to work around a VM
4126 bug in the 2.0 kernel. I've heard a report that a RAID user was able
4127 to trigger it even using a 2.2 kernel, but hopefully it will not be
4128 needed for most Linux 2.2 users.
4130 Fixed miscellaneous documentation and man pages.
4135 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
4136 in e2fsck's pass1.c really should have been static.
4138 The return value of the uuid_compare() function was changed to make it
4139 match with the convetions used by strcmp, memcmp, and Paul Leach's
4140 UUID sample document.
4142 The "make depend" process has now been made more automated; it now
4143 automatically word-wraps the dependencies, and only replaces source
4144 Makefile.in if there has been a change in the dependencies. Also, a
4145 top-level "make depend" now recurses through all the subdirectories
4148 The Makefile in .../util has been changed so that subst is built using
4149 the native C compiler during a cross-compilation, since the subst
4150 program is only used during the build process. Also add an explicit
4151 rule to build util/subst by cd'ing to the correct directory and
4154 The man directories are defined in terms mandir, so that the configure
4155 script can override the location of the manual pages.
4157 The config files have been updated to recognize new machine types for
4158 both the i386 and alpha families.
4160 Fsck has been modified so that it will accurately create an
4161 fsck_instance even when the noexecute flag is set. This allows for
4162 accurate debugging of the fsck pass structure. Also, when the verbose
4163 flag is given twice, fsck will print debugging information about when
4164 fsck is waiting for jobs to finish.
4167 E2fsprogs 1.14 (January 9, 1999)
4168 ================================
4170 Fix the fstab parsing code so that it can handle blank lines and
4171 comment characters. Also, missing pass numbers need to be treated as
4174 Fixed a bug in e2fsck where under some circumstances (when e2fsck
4175 needs to restart processing after fixing an egregious inconsistency)
4176 it would try to access already freed memory.
4178 E2fsck now prints non-printable characters in directory entries and
4179 pathnames using '^' and 'M-' notation.
4181 Fixed chattr so that it will ignore symbolic links when doing
4182 recursive descent traversals. For both chattr and lsattr, no longer
4183 print the version string unless the -V option is given.
4185 Allow the system administrator to directly specify the number of
4186 inodes desired in the filesystem, for some special cases where this is
4189 Fix portability problems so that e2fsprogs can be compiled under Linux
4190 1.2 systems and Solaris systems.
4192 Update the config.guess file with a more recent version that will
4193 identify newer Linux platforms.
4198 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
4199 an inode number of zero is passed to them.
4201 E2fsprogs 1.13 (December 15, 1998)
4202 ==================================
4204 Fixed a bug in debugfs where an error messages weren't getting printed
4205 when the ext2 library routines to read inodes returned errors in the
4206 stat, cmri and rm commands.
4208 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
4209 provided, it won't create an inode table smaller than the minimum
4210 number of inodes required for a proper ext2 filesystem.
4212 Fsck now parses the /etc/fstab file directly (instead of using
4213 getmntent()), so that it can distinguish between a missing pass number
4214 field and pass number field of zero. This caused problems for
4215 diskless workstations where all of the filesystems in /etc/fstab have
4216 an explicit pass number of zero, and fsck could not distinguish this
4217 from a /etc/fstab file with missing pass numbers.
4219 E2fsck will create a /lost+found directory if there isn't one in the
4220 filesystem, since it's safer to create the lost+found directory before
4223 Fixed e2fsck so that it would detect bogus immutable inodes which
4224 happen to be sockets and FIFO files, and offer to clear them.
4226 If a filesystem has multiple reasons why it needs to be checked, and
4227 one of the reasons is that it is uncleanly mounted, e2fsck will print
4228 that as the reason why the filesystem is being checked.
4230 Cleaned up the output routines of mke2fs so that it doesn't overflow
4231 an 80 column display when formating really big filesystems.
4233 Added a sanity check to e2fsck to make sure that file descriptors 0,
4234 1, 2 are open before opening the hard disk. This avoids a problem
4235 where a broken program might exec e2fsck with those file descriptors
4236 closed, which would cause disastrous results if the kernel returns a
4237 file descriptor for the block device which is also used by FILE *
4240 Fixed up the e2fsck progress reporting functions so that the values
4241 reliably reach 100% at the completion of all of the e2fsck passes.
4243 Fixed minor documentation bugs in man pages and usage messages.
4248 Fixed a number of lint warnings in the ext2fs library and potential
4249 portability problems from other OS's header files that might define
4250 CPP macros for names like "max" and "min".
4252 ext2fs_badblocks_list_add() has been made more efficient when it needs
4253 to grow the bad blocks list.
4255 Fixed a bug in e2fsck which caused it to dereference a freed pointer
4256 just before exiting.
4258 Fixed the substition process for generating the mk_cmds and compile_et
4259 scripts so that they will work outside of the build tree.
4261 Add sanity check to e2fsck so that if an internal routine
4262 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
4263 and causing a core dump. This should never happen, but...
4265 E2fsprogs 1.12 (July 9, 1998)
4266 ==================================
4268 E2fsprogs now works with glibc (at least with the version shipped wtih
4269 RedHat 5.0). The ext2fs_llseek() function should now work even with
4270 i386 ELF shared libraries and if llseek() is not present. We also
4271 explicitly do a configure test to see if (a) llseek is in libc, and
4272 (b) if llseek is declared in the system header files. (See standard
4273 complaints about libc developers don't understand the concept of
4274 compatibility with previous versions of libc.)
4276 The ext2fs library now writes out the block group number in each of
4277 the superblock copies. This makes it easier to automatically
4278 determine the starting block group of the filesystem when the block
4279 group information is trashed.
4281 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
4282 which means that e2fsprogs will ignore the high 8 bits of the
4283 directory entry's name_len field, so that it can be used for other
4286 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
4287 E2fsprogs will now support filesystems with 64-bit sized files.
4289 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
4291 Added new program "e2label", contributed by Andries Brouwer. E2label
4292 provides an easy-to-use interface to modify the filesystem label.
4294 Fixed bug so that lsattr -v works instead of producing a core dump.
4296 Fixed a minor bug in mke2fs so that all groups with bad superblock
4297 backup blocks are printed (not just the first one).
4299 Mke2fs will check the size of the device, and if the user specifies a
4300 filesystem size larger than the apparent size of the device it will
4301 print a warning message and ask if the user wants to proceed.
4303 E2fsck has a new option -C, which sends completion information to the
4304 specified file descriptor. For the most part, this is intended for
4305 programs to use, although -C 0 will print a spinning character to the
4306 stdout device, which may be useful for users who want to see something
4307 happening while e2fsck goes about its business.
4309 Fixed a bug in e2fsck which could cause a core dump when it needs to
4310 expand the /lost+found directory, and sometimes the bitmaps haven't
4311 been merged in. Also fixed a related bug where ext2fs_write_dir_block
4312 was used to write out a non-directory block. (Which would be bad on a
4313 non-Intel platform with byte swapping going on.)
4315 Fixed bug in e2fsck where it would print a "programming error" message
4316 instead of correctly identifying where a bad block was in used when
4317 the bad block was in a non-primary superblock or block group
4318 descriptor. Also fixed a related bug when sparse superblocks are in
4319 use and there is a bad block where a superblock or block group
4320 descriptor would have been in a group that doesn't include a
4323 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
4324 the block group descriptor table is corrupt, it was possible to try to
4325 allocate a huge array, fail, and then abort e2fsck.
4326 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
4327 and subsitutes reasonable values if the descriptors are obviously bogus.
4329 If e2fsck finds a device file which has the immutable flag set and the
4330 i_blocks beyond the normal device number are non-zero, e2fsck will
4331 offer to remove it, since it's probably caused by garbage in the inode
4334 When opening a filesystem, e2fsck specially checks for the EROFS error
4335 code, and prints a specific error message to the user which is more
4338 If the filesystem revision is too high, change the e2fsck to print
4339 that this is either because e2fsck is out of date, or because the
4340 superblock is corrupt.
4342 E2fsck now checks for directories that have duplicate '.' and '..'
4343 entries, and fixes this corruption.
4345 E2fsck no longer forces a sync of the filesystem (with attendant sleep
4346 calls) at all times. The ext2fs_flush() function now performs a sync
4347 only if it needed to write data blocks to disk.
4349 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
4350 certain errors would not be properly reported.
4352 Updated and expanded a few points in the man pages which users
4353 complained wheren't explicit enough.
4355 Added special case byte-swapping code if compiling on the PowerPC, to
4356 accomodate the strange big-endian variant of the ext2 filesystem that
4357 was previously used on the PowerPC port.
4363 Removed C++ keywords from the ext2fs libraries so that it could be
4366 E2fsck's internal organization has now been massively reorganized so
4367 that pass*.c don't have any printf statements. Instead, all problems
4368 are reported through the fix_problem() abstraction interface. E2fsck
4369 has also been revamped so that it can be called as a library from a
4372 Added new fileio primitives in libext2fs for reading and writing
4373 files on an unmounted ext2 filesystem. This interface is now used by
4376 Added a new libext2fs function for mapping logical block numbers of
4377 a file to a physical block number.
4379 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
4380 a block, zeros it, and updates the filesystem accounting records
4383 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
4384 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
4386 The libext2fs functions now use a set of memory allocation wrapper
4387 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
4388 instead of malloc, free, and resize. This makes it easier for us to
4389 be ported to strange environments where malloc, et. al. aren't
4390 necessarily available.
4392 Change the libext2fs fucntion to return ext2-specific error codes
4393 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
4394 and depending on the existence of system error codes (such as EEXIST
4397 Renamed io.h to ext2_io.h to avoid collision with other OS's header
4400 Add protection against ext2_io.h and ext2fs.h being included multiple
4403 The types used for memory lengths, etc. have been made more portable.
4404 In generla, the code has been made 16-bit safe. Added Mark
4405 Habersack's contributed DOS disk i/o routines.
4407 Miscellaneous portability fixes, including not depending on char's
4410 The io_channel structure has a new element, app_data, which is
4411 initialized by the ext2fs routines to contain a copy of the filesystem
4414 ext2fs_check_directory()'s callback function may now return the error
4415 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
4416 really do the checking, despite the presence of the callback function.
4419 E2fsprosg 1.11 (June 17, 1997)
4420 ==============================
4422 Fixed e2fsck to detect (previously ignored) conflicts between the
4423 superblock or block group descriptors and block bitmaps, inode
4424 bitmaps, and inode tables.
4426 Fixed bug in e2fsck so that when the message printed out when a block
4427 or inode bitmap conflicts with other data, it has the correct group
4430 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
4431 to badblocks. This meant that not all of the filesystem was being
4432 tested for bad blocks!
4434 Fixed an array boundary overrun case which cropped up in
4435 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
4438 Adjusted the number of columns printed by mke2fs when displaying the
4439 superblock backups to avoid running over 80 columns when making a
4440 really big filesystem.
4442 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
4443 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
4444 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
4449 Fixed install rule in lib/ss so that ss_err.h is actually getting
4452 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
4453 bassed back to the caller.
4455 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
4456 setting the current inode number (which meant this function wasn't
4459 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
4460 blocks in the bitmap when increasing the size of the bitmap.
4462 Changed the initial number of blocks allocated by ext2fs_init_dblist()
4463 to be more realistic.
4465 Added a new function ext2fs_allocate_group_table, which sets up the
4466 group descriptor information (and allocates inode and block bitmaps,
4467 and inode tables for a particular group). The function was created by
4468 factoring out code form ext2fs_allocate_tables().
4470 Added a new function ext2fs_move_blocks which takes a bitmap of the
4471 blocks to be moved, and moves them to another location on the
4474 Make the unix_io channel's io_channel_flush implementation calls sync()
4475 to to flush the kernel buffers to disk.
4477 Added a new function ext2fs_dblist_count returns the number of
4478 directory blocks in dblist.
4481 E2fsprogs 1.10 (April 24, 1997)
4482 ===============================
4484 Mke2fs once again defaults to creating revision #0 filesystems, since
4485 people were complaining about breaking compatibility with 1.2 kernels.
4486 Warning messages were added to the mke2fs and tune2fs man pages that
4487 the sparse superblock option isn't supported by most kernels yet (1.2
4488 and 2.0 both don't support parse superblocks.)
4490 Added new flag to mke2fs, -R <raid options>, which allows the user to
4491 tell mke2fs about the RAID configuration of the filesystem. Currently
4492 the only supported raid option is "stride" which specifies the width
4495 Fixed bug in e2fsck where pass1b would bomb out if there were any
4496 blocks marked bad in the inode table.
4498 Fixed rare bug in mke2fs where if the user had a very unlucky number
4499 of blocks in a filesystem (probability less than .002) the resulting
4500 filesystem would be corrupt in the last block group.
4502 Fixed bug where if e2fsck tried to allocate a block to fix a
4503 filesystem corruption problem and the filesystem had no free blocks,
4504 ext2fs_new_block() would loop forever.
4506 The configure script now checks explicitly to see if "-static" works,
4507 since that can't be assumed to be true --- RedHat doesn't install
4508 libc-static by default.
4510 Fixed bug in libext2's block iterator functions where under some
4511 cirmcustances, file with holes would cause the bcount parameter to the
4512 callback function to be incorrect. This bug didn't affect any of
4513 e2fsprogs programs, but it was discovered by Paul Mackerras, the
4514 author of the PPC boot loader.
4516 Removed use of static variables to store the inode cache in libext2fs.
4517 This caused problems if more than one filesystem was accessed via
4518 libext2fs (static variables in libraries are generally a bad idea).
4519 Again, this didn't affect e2fsprogs programs, but it was discovered by
4522 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
4523 will compile cleanly with 1.2.13 kernels (even with a.out shared
4529 Added new functions to duplicate an ext2 filesystem handle, and its
4530 associated substructure. New functions: ext2fs_dup_handle(),
4531 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
4532 Other structures, such as the io_channel and the inode_cache, now have
4533 a ref count so that they only get freed when they are no longer used
4534 by any filesystem handle. (These functions were added as part of the
4535 development effort for an ext2 resizer).
4537 E2fsprogs 1.09 (April 14, 1997)
4538 ===============================
4540 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
4541 accidentally introduced in the 1.08 release. The overhead calculation
4542 was accidentally removed, which caused ext2fs_initialize() to not
4543 notice when the filesystem size needed to be adjusted down because
4544 there wasn't enough space in the last block group.
4546 Fixed bug in version parsing library routine; it was always parsing
4547 the library version string, instead of using the passed-in string.
4549 Clarified chattr man page.
4551 E2fsprogs 1.08 (April 10, 1997)
4552 ===============================
4554 E2fsck 1.07 was very slow when checking very large filesystems with a
4555 lot of files that had hard links (i.e., news spools). This was fixed
4556 by seriously revamping the icount abstraction. Added a formal test
4557 suite for the icount abstraction.
4559 Debugfs now has a "-l" option to the "ls" command, which lists the
4560 inode number, permissions, owner, group, size, and name of the files
4563 Fix a bug in e2fsck where when a directory had its blocks moved to
4564 another location during the pass 1b processing, the directory block
4565 list wasn't updated, so pass 2 wouldn't check (and correct) the
4566 correct directory block.
4568 E2fsck will now treat inodes which contain blocks which are claimed by
4569 the filesystem metadata by treating them as multiply claimed blocks.
4570 This way, the data in those blocks can be copied to a new block during
4571 the pass 1b--1d processing.
4573 E2fsck will attempt to determine the correct superblock number and
4574 display it in the diagnostic and warning messages if possible.
4576 Add support for a new (incompatible) feature, "sparse_super". This
4577 feature reduces the number of blocks which contain copies of backup
4578 superblocks and block group descriptors. (It is only an incompatible
4579 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
4580 support a new -s option; e2fsck will recognize filesystems built with
4581 this feature turned on.
4583 E2fsck now checks the library to make sure is the correct version,
4584 using new library functions. (This helps to diagnose incorrectly
4585 installed e2fsprogs distributions.)
4587 Dumpe2fs now prints more information; its now prints the the
4588 filesystem revision number, the filesystem sparse_super feature (if
4589 present), the block ranges for each block group, and the offset from
4590 the beginning of the block group.
4592 Mke2fs now distributes the inode and block bitmap blok so that the
4593 won't be concentrated in one or two disks in RAID/striping setups.
4594 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
4595 choose the largest blocks per group that be chosen. (For 2k blocks,
4596 you can have up to 16384 blocks/group; for 4k blocks, you can have up
4597 to 32768 blocks/group.) Previously mke2fs would not allow
4598 specification of more than 8192 blocks per group, even if you were
4599 using a 2k or 4k block group.
4604 Added a new function ext2fs_create_icount2() which takes a "hint"
4605 argument. This hint argument presets the icount array with the list
4606 of inodes which actually need to be in the icount array. This really
4607 helps to speed up e2fsck.
4609 Added a new function ext2fs_icount_validate() which checks the rep
4610 invariant for the icount structure. This is used mostly for testing.
4612 The error mesasage given when a bad inode number is passed to
4613 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
4614 EXT2FS_UNMARK_ERROR).
4616 Added a new function ext2fs_set_dir_block which sets the block of a
4617 dblist entry, given the directory inode and blockcnt.
4619 Added a new function ext2fs_get_library_version() which returns the
4620 current library version, and ext2fs_parse_version_string() which
4621 returns a version number based on a e2fsprogs version string.
4623 The icount functions will return EINVAL if the passed in inode number
4626 E2fsprogs 1.07 (March 9, 1997)
4627 ==============================
4629 E2fsck is now uses much less memory when checking really large
4630 filesystems (or rather, filesystems with a large number of inodes).
4631 Previously a filesystem with 1 million inodes required 4 megabytes of
4632 memory to store inode count statistics; that storage requirement has
4633 now been reduced to roughly half a megabyte.
4635 E2fsck can now properly deal with bad blocks appearing inside the
4636 inode table. Instead of trying to relocate the inode table (which
4637 often failed because there wasn't enough space), the inodes in the bad
4638 block are marked as in use.
4640 E2fsck will automatically try to use the backup superblocks if the
4641 primary superblocks have a bad magic number or have missing meta-data
4642 blocks (or meta-data blocks which are out of range).
4644 E2fsck's pass 3 has been made more efficient; most noticeable on
4645 filesystems with a very large number of directories.
4647 Completely revamped e2fsck's system of printing problem reports. It
4648 is now table driven, to make them more easily customizeable and
4649 extendable. Error messages which can be printed out during preen mode
4650 are now one line long.
4652 Fixed e2fsck's filesystem swapping code so that it won't try to swap
4653 fast symbolic links or deleted files.
4655 Fixed e2fsck core dumping when fixing a filesystem which has no
4656 directories (not even a root directory).
4658 Added a check to e2fsck to make sure that the length of every
4659 directory entry is a multiple of 4 (since the kernel complains if it
4662 Added a check to e2fsck to make sure that a directory entry isn't a
4663 link to the root directory, since that isn't allowed.
4665 Added a check to e2fsk to now make sure the '.' and '..' directory
4666 entries are null terminated, since the 2.0 kernel requires it.
4668 Added check to write_bitmaps() to make sure the superblock doesn't get
4669 trashed if the inode or block bitmap is marked as being block zero.
4671 Added checking of the new feature set fields in the superblock, to
4672 avoid dealing with new filesystem features that this package wasn't
4675 Fixed a fencepost error in ext2fs_new_block() which would occasionally
4676 try to allocate a block beyond the end of a filesystem.
4678 When the UUID library picks a random IEEE 802 address (because it
4679 can't find one from a network card), it sets the multicast bit, to
4680 avoid conflicting with a legitimate IEEE 802 address.
4682 Mke2fs now sets the root directory's owner to be the real uid of the
4683 user running mke2fs. If the real uid is non-zero, it also sets
4684 the group ownership of the root directory to be the real group-id of
4685 the user running mke2fs.
4687 Mke2fs now has more intelligent error checking when it is given a
4688 non-existent device.
4690 When badblocks is given the -vv option, it now updates the block that
4691 it is currently testing on every block.
4693 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
4694 currently correctly if PATH wasn't already set.
4696 Shared libraries now built with dependencies. This allows the shared
4697 library files to be used with dlopen(); it also makes the transition
4698 to libc 6 easier, since ld.so can tell which libc a particular shared
4699 library expects to use.
4704 Added new abstraction (defined in dblist.c) for maintaining a list of
4705 blocks which belongs to directories. This is used in e2fsck and other
4706 programs which need to iterate over all directories.
4708 Added new functions which test to see if a contiguous range of blocks
4709 (or inodes) are available. (ext2fs_*_bitmap_range).
4711 Added new function (ext2_inode_has_valid_blocks) which returns true if
4712 an inode has valid blocks. (moved from e2fsck code).
4714 Added new function (ext2fs_allocate_tables) which allocates the
4715 meta-data blocks as part of initializing a filesystem. (moved from
4718 Added a new I/O manager for testing purposes. It will either allow a
4719 program to intercept I/O requests, or print debugging messages to
4720 trace the activity of a program using the I/O manager.
4722 The badblocks_list functions now store the bad blocks in a sorted
4723 order, and use a binary search to speed up badblocks_list_test.
4725 The inode scan function ext2fs_get_next_inode() may now return a soft
4726 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
4727 those cases where part of an inode table is missing or there is a bad
4728 block in the inode table.
4730 Added a new function (ext2fs_block_iterate2) which adds new arguments to
4731 the callback function to return a pointer (block and offset) to the
4732 reference of the block.
4734 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
4735 application to jump to a particular block group while doing an inode
4738 The badblocks list functions were renamed from badblocks_* to
4739 ext2fs_badblocks_*. Backwards compatibility functions are available
4740 for now, but programs should be modified to use the new interface.
4742 Some of the library functions were reorganized into separate files to
4743 reduce the size of some programs which statically link against the
4746 Put in some miscellaneous fixes for the Alpha platform.
4749 E2fsprogs 1.06 (October 7, 1996)
4750 ================================
4752 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
4753 smash the backup copies in ext2fs_close(). (The problem was that when
4754 e2fsck -p discovered the problem, while it was closing the filesystem
4755 and exiting, it was also blowing away the backup superblocks on the
4756 disk, which was less than friendly.) We now make it the case that we
4757 only write out the backup superblock and the back block descriptors if
4758 the filesystem is completely free from problems.
4760 Fixed a bug in block_interate in the lib/ext2fs library which caused
4761 e2fsck to fail on GNU Hurd-created filesystems.
4763 Add support for Linux/FT's bootloader, which actually uses
4764 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
4767 Add support for the "A" (no atime update) attribute. (Note: this
4768 attribute is not yet in production kernels.)
4770 The test suite is not automatically run when doing a "make all" from
4771 the top level directory. Users should manually run "make check" if
4772 they wish to run the test suite.
4774 Upon a preenhalt(), make the printed message more explicit that
4775 running e2fsck "MANAULLY" means without the -p or -a options.
4777 In e2fsck, if a disconnected inode is zero-length, offer to clear it
4778 instead of offering to connect it to lost+found.
4780 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
4781 e2fsck to be run over it, change e2fsck to explicitly display this
4784 For dumpe2fs and e2fsck, cause the -V option to print out which
4785 version of the ext2fs library is actually getting used. (This will
4786 help detect mismatches of using a 1.06 utility with a 1.05 library,
4792 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
4793 the naming convention.
4795 In ext2fs_initialize(), make sure the description for the inode bitmap
4796 is correctly initialize.
4798 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
4800 E2fsprogs 1.05 (September 7, 1996)
4801 ==================================
4803 Add support for new fields in the ext2 superblock --- volume name,
4804 volume UUID, and last mounted field. Dumpe2fs displays these fields,
4805 tune2fs and mke2fs allows you to set them. E2fsck will automatically
4806 generate a UUID for those volumes that don't have them.
4808 Put in support for e2fsck to recognize HURD specific ext2 features ---
4809 most notably, the translator block. The e2fsprogs tools will now use
4810 the creator_os field in the superblock to correctly handle different
4811 OS-specific variants of the ext2 filesystem.
4813 E2fsck now fixes inodes which have a the deletion time set, but which
4814 have a non-zero i_link_count field by offering to clear the deletion
4815 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
4816 ext2 kernel behavior) and offered to unlink the file.
4818 If e2fsck sets the clean bit, but nothing else, set the exit code
4819 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
4820 set the filesystem valid bit when it was previously cleared. :-) This
4821 was needed to make the HURD fsck driver happy.
4823 If the user refuses to attach an unattached inode, e2fsck will no
4824 longer set the inode's link count. Otherwise, the inode would end up
4825 getting marked as unused, which might cause loss of data later.
4827 Make the message issued by e2fsck when the superblock is corrupt less
4828 confusing for users. It now mentions that another reason for the
4829 "corrupt superblock" message might be that the partition might not be
4830 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
4832 Make the libext2 library more robuest so that e2fsck won't coredump on
4833 an illegal superblock where the blocksize is zero. (f_crashdisk is
4836 By default, create filesystems where the default checkinterval is 6
4837 months (180 days). Linux servers can be robust enough that 20 reboots
4838 can be a long, long time.
4840 Added configure flag --enable-old-bitops, which forces the bitops to
4841 use the old (native) bitmask operations. By default on the sparc
4842 platform, the standard ext2 bit ordering is now used.
4844 Added a new feature to e2fsck to byte-swap filesystems; this can be
4845 used to convert old m68k filesystems to use the standard byte-order
4846 storage for the superblock, inodes, and directory blocks. This
4847 function is invoked by using the '-s' option to e2fsck.
4849 Debugfs's "dump" command has been enhanced so that it writes out the
4850 exact size of the file so that the nulls at the end of the file are
4851 eliminated. The command also accept a new "-p" option which will
4852 attempt preserve to preserve the ownernship, permissions, and
4853 file modification/access times.
4855 Debugfs has two new options, -f and -R. The -R option allows the user
4856 to execute a single debugfs command from the command line. The -f
4857 option allows the user to specify a "command file" containing debugfs
4858 commands which will get executed.
4860 Dumpe2fs now pretty prints the check interval, instead of just
4861 printing the check interval as a number of seconds.
4863 Fix bugs in debugfs: the params command when no filesystem is opened
4864 no longer causes a core dump. It is now possible to unlink a file
4865 when a pathame containing a '/' is specified.
4867 Tune2fs has a new -C option which sets the number of times the
4868 filesystem has been mounted.
4870 Fix the chattr '-v' option so that it actually works. Chattr was
4871 being buggy about the -v option parsing.
4876 The directory lib/uuid contains a set of library routines to generate
4877 DCE compatible UUIDs.
4879 Extended ext2fs_namei() to handle symbolic links. Added new function
4880 ext2fs_nami_follow() which will follow last symbolic link in the case
4881 where the pathname points to a sym link.
4883 The ext2fs_block_iterate function will now return the HURD translator
4884 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
4885 iterator to return data blocks only. The ext2fs.h file now defines
4886 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
4887 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
4888 count field of the iterator callback function.
4890 The test script driver now takes an optional second argument, which is
4891 the test case to be run. This allows you to run a test case without
4892 needing to run the entire test suite.
4894 On Linux ELF systems, install the .so files in the correct places
4895 (/usr/lib). The .so files must be stored in the same directory as the
4898 Fixed miscellaneous HURD compilation issues with header file being
4899 included in the right order.
4901 Fixed debugfs so that it resets optind to zero, not one, since setting
4902 optind to zero is more correct.
4905 E2fsprogs 1.04 (May 16, 1996)
4906 =============================
4908 First "official" (1.03 was a limited release only) to support building
4909 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
4912 This package includes a RPM specs file, that it can be built using the
4913 RedHat Package Manager.
4915 E2fsck now prints a hint that if there are lots of incorrectly located
4916 inode bitmaps, block bitmaps, and inode table blocks, the user might
4917 want to try using e2fsck -b 8193 first, to see if that fares any
4920 For ext2 filesystem written with the hurd, debugfs will now print out
4921 the translator field when printing an inode structure.
4923 Lots of miscellaneous linking/installation cleanups:
4925 Libraries are now linked using a relative pathname, instead of
4926 relying on -L working correct. It doesn't, in many cases, including
4927 current versions of GNU ld. This guarantees that the build tree is
4928 linking with the right libraries, instead of the ones installed in
4931 Header files, man pages, and the et/ss shell scripts are now
4932 generated using a custom substitution script, instead of relying on
4933 the configure script. This prevents needless recompilation of
4934 files; in addition, the custom substitution script is much faster.
4936 e2fsck may now be linked dynamically, by using the
4937 --enable-dynamic-e2fsck flag to configure. This is not recommended,
4938 since it increases e2fsck's dependence on other files, but some
4939 people need to save disk space, and other critical programs on their
4940 systems were being linked dynamically anyway.
4942 Programs such as fsck which didn't need to be linked against
4943 libext2fs (or mke2fs which didn't need to be linked against libe2p)
4944 only link against libraries they actually need. Otherwise, those
4945 programs would require the presense of libraries that otherwise
4946 could be removed from a rescuse diskette.
4948 The ss include files are now installed correctly so they can
4949 actually be used by another package.
4951 If the profiling libraries are built, they are now installed on a
4952 "make install-libs".
4955 E2fsprogs 1.03 (March 27, 1996)
4956 ===============================
4958 Change the m68k bit numbering for bitmasks to match the bit numbering
4959 used by all other ext2 implementations. (This change was requested by
4960 the m68k kernel development team.)
4962 Support (in-development) filesystem format revision which supports
4963 (among other things) dynamically sized inodes.
4965 Fixed a bug in the ext2 library so that an intelligent error is
4966 returned if mke2fs is run with a ridiculously small number of blocks
4969 Fixed a bug in the ext2 library which required that the device be
4970 openable in read/write mode in order to determine its size. This
4971 caused e2fsck -n to require read/write access when it was not
4972 previously necessary.
4974 Fixed a bug in e2fsck which casued it to occasionally fail the test
4975 suite depending on which version of the floating point library it was
4978 Fixed a bug in e2fsck so that it now halts with a fatal error when
4979 certain superblock consistency checks fail. Previously it continued
4980 running e2fsck, with some potential confusing/damaging consequences.
4982 Added new flag to fsck which allows the root to be checked in parallel
4983 with other filesytems. This is not the safest thing in the world to
4984 do, but some system administrators really wanted it.
4986 Fixed -Wall flames in lib/ss.
4989 E2fsprogs 1.02 (January 16, 1996)
4990 =================================
4992 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
4994 Change e2fsck to print statistics of how many non-contiguous files are
4995 on the system. Note that a file which is larger than 8k blocks, it is
4996 guaranteed to be non-contiguous.
4998 In mke2fs, print a warning message if a user tries to format a whole
4999 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
5000 whole disk, the -F (force) option forces mke2fs to format a whole disk
5003 Fix a bug in fsck where in some cases it might start checking
5004 partitions in the next pass before it finishes checking partitions in
5005 the current pass. This still won't cause two partitions on the same
5006 disk will be checked, so it's rarely a problem in real life.
5008 Patch lsattr so that it won't hang when checking a named pipe.
5010 Minor compilation fixes:
5011 * Fix the order of libraries that were linked in debugfs.
5012 * Allow the sources to be compiled with -ansi turned on.
