1 E2fsprogs 1.39-WIP (December 10, 2005)
2 =====================================
4 E2fsck will detect if the superblock's last mount field or last write
5 field is in the future, and offer to fix if so. (Addresses Debian Bug
8 Fix e2fsck from segfaulting on disconnected inodes that contain one or
9 more extended attributes. (Addresses Debian Bug: #316736, #318463)
11 E2fsck will stop and print a warning if the user tries running a
12 read/write badblocks test on a read-only mounted root filesystem.
14 Fix mke2fs so that it correctly creates external journals on
15 big-endian machines (such as a S/390).
17 Fix debugfs's set_inode_field command so it can properly set the frag,
18 fsize, uid_high, gid_high, and author fields in the inode instead of
19 silently failing, and so that setting the i_size actually sets i_size
22 Add a new debugfs command, set_current_time, which sets fs->now so
23 that regression test suites can repeatedly modify the filesystem's
26 Fix a display bug in "badblocks -sv" so that the done message properly
27 clears the block number at the end of the test. (Addresses Debian Bug
30 Allow fractional percentages to the -m option in mke2fs and tune2fs
31 (Addresses Debian Bug: #80205)
33 Use fstat/fstat64 in getsize.c if the the target is a regular file,
34 instead of attempting to do a binary search. Fix some fd leaks in
37 Fix the blkid library so that it notices when an ext2 filesystem is
40 Improve the blkid's library VFAT/FAT detection; it now understands
41 labels stored in the root directory, and is more paranoid about
42 checking the FAT superblock values.
44 Add support for the reiser4 and software suspend partitions to the
45 blkid library. Also add support for extract the label from iso9660
48 Fix a compile_et bug which miscount the number of error messages if
49 continuations are used in the .et file.
51 Add extra sanity checks to protect users from unusual cirucmstances
52 where /etc/mtab may not be sane, by checking to see if the device is
53 reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
56 Updated Dutch translation.
58 Fix use-after-free bug in e2fsck when finishing up the use of the
59 e2fsck context structure.
61 Fixed spelling mistakes, typos, and otherwise clarified man pages.
62 (Addresses Debian Bugs: #329859, #322188, #316811)
64 Fixed various Debian packaging issues --- see debian/changelog for
65 details. (Addresses Debian Bugs #317862, #320389, #290429, #310950,
71 Add valgrind support to the regression test suites, and eliminate
72 false positives from valgrind.
74 Add a regression test suite for the blkid library.
76 Fix a fencepost error in resize2fs caught by valgrind.
78 Fix compiler warnings about missing memcpy prototypes.
80 We no longer have the sparc assembly code in the header file any more,
81 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
82 break compiles on the sparc architectures when using gcc.
84 In the libext2fs library, add the new field fs->now which if non-zero
85 is used instead of the system time when setting various filesystem
86 fields (last modified time, last write time, etc.)
88 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
89 ext2fs.h which is needed since the inline functions use memcpy().
90 (Addresses Sourceforge Bug #1251062)
92 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
93 the build system when building files in the util directory which are
94 needed during the build process. This avoids potential problems when
95 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
96 are not recognized as valid by the host compiler. (Addresses
97 Sourceforge Bug #1261547)
99 Clean up the blkid library by making the superblock and generic i/o
100 functions to be more generic. Clean up interface to the probe
101 function, and fix memory leak. Finallly, remove an unneeded reference
102 to probe.h in the lib/blkid/resolve.c
104 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
105 of invalid block #'s.
107 Fix various gcc -Wall complaints.
109 Add a dependency to make sure that the subdirectories are created
110 before creating all of the object files, in order to address parallel
111 build problem in the library Makefiles. (Addresses Sourceforge Bug:
114 Add $(LDFLAGS) to the command line argument when generating an ELF or
115 Solaris shared library, to allow cross-compile and other builds that
116 might need to specify -L paths to needed libraries. (Addresses
117 Sourceforge Bug #1261549)
120 E2fsprogs 1.38 (June 30, 2005)
121 ==============================
123 Fix blkid's test programs (built with "make check") compile correctly
124 even without "configure --enable-blkid-debug".
126 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
127 type aliasing rules on newer gcc compilers. (Addresses Red Hat
130 Fix com_err library to make it more compatible with recent changes
131 made to the com_err library in MIT Kerberos V5 version 1.4.
132 (Addresses Sourcefroge Bug #1150146)
134 General cleanup of messages printed by e2fsprogs programs for grammar,
135 consistency, and to make life easier for translators. Fixed a few
136 strings containing English that had not been marked as needing
137 translations. Removed strings that do not need to be translated, to
138 make life easier for translators.
140 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
141 test to see if a device appears to be in use instead of just relying
142 on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
144 Fix portability problem in the filefrag program affecting platforms
145 where the size of an integer is smaller than the size of a long.
146 (Addresses Debian Bug #309655)
148 Mke2fs will now use a larger journal by default for filesystems
149 greater than 4GB. (128 MB instead of 32MB).
151 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
152 unless forced. This is to avoid signed vs. unsigned kernel bugs in
153 block numbers that still need to be fixed.
155 The blkid program has a new option which will more efficiently search
156 for device when it is known (or expected) that only one matching
157 device will be found in the system, such as when doing a lookup by
160 Debian's e2fsprogs-specific initrd fragment will avoid including
161 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
162 and LD_LIBRARY_PATH, and filtering out libraries found in
163 /etc/ld.so.preload. (Addresses Debian Bug: #304003)
165 Fixed a potential portability issue in the blkid programs for
166 architectures where the char type is unsigned. (Addresses Sourceforge
169 Fix a bug in filefrag so that it doesn't falsely count an extra
170 discontinuity when the first block found is an indirect block.
171 (Addresses Debian Bug #307607).
173 Fix blkid's recognition of cramfs filesystems, and enhance it to be
174 able to handle cramfs labels.
176 Fix debugfs's stat command to not core dump when a filesystem is not
179 Fix e2fsck's handling of error conditions caused by the resize inode
180 claiming blocks that are also used by other inodes, a filesystem
181 corruption which was commonly caused by a bug in Fedora Core 3's
184 Fixed bug in filefrag which caused it to fail on non-ext2/3
185 filesystems. (Addresses Debian Bug: #303509)
187 If the superblock last mount time indicates that the system clock may
188 not be accurate, then e2fsck will omit checking inodes' deletion time
189 field for indications of a potential corrupted orphaned inode list.
190 (Previously e2fsck only ommited these LOW_DTIME checks when the
191 superblock's last write time looked insane.)
193 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
194 (Addresses Debian bug #302200)
196 Make the blkid library more paranoid about being run from setgid
197 programs, and to use __secure_getenv() from libc if it is available.
199 Fixed spelling mistakes, typos, and otherwise clarified man pages.
200 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
201 and Sourceforge Bug: #1189803)
203 Updated and fixed translations.
205 Fixed various Debian packaging issues --- see debian/changelog for
211 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
212 changed to take an unsigned int for the bit number. Negative bit
213 numbers were never allowed (and didn't make any sense), so this should
214 be a safe change. This is needed to allow safe use of block numbers
215 greater than or equal to 2**31.
217 The compile_et program will avoid recreating generated foo_err.c and
218 foo_err.h files if no changes are necessary. The compile_et program
219 will also atomically replace these files to avoid a potential parallel
220 build race problem on SMP systems. (Addresses Sourceforge Bug:
223 Added a new function to the blkid library, blkid_probe_all_new(),
224 which only probes newly added disk devices, and change
225 blkid_find_dev_with_tag() to use this function so that when a
226 requested tag is not found, devices that were previously not checked
227 are searched before searching all devices in the system.
229 Added new functions to the blkid library, blkid_dev_set_search() and
232 E2fsck's problem strings can now use @m and @n as abbrevations for
233 "multiply-claimed" and "invalid", respectively.
235 The e2fsprog.pot file now has an explanation of how the @-expansion
236 and %-expansion works, and strings in e2fsck/problem.c which contain @
237 characters now have comments in e2fsprogs.pot with the @-expansion to
238 make life easier for translators.
240 Fixed missing return values in the ext2fs library which could cause it
241 to return random garbage in certain error conditions.
243 Allow the current time to be overriden via the E2FSCK_TIME environment
244 variable for use in regression tests.
246 The test scrpit driver program now exits with a non-zero status if
247 there any of its test that it ran failed.
249 Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
252 Fixed "make check" so that it compiles correctly even when e2fsprogs'
253 header files have not be installed in the system include directories.
254 (Addresses Sourceforge Bug: #1180572)
256 Fixed gcc -Wall nits.
259 E2fsprogs 1.37 (March 21, 2005)
260 ===============================
262 Add support for checking the validity of Extended Attributes stored in
265 Add support for dumping the contents of large inodes to debugfs,
266 including the extended attributes stored in inodes.
268 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
269 when we create a new inode we make sure that the extra information in
270 the inode (any extra fields in a large inode and any ea-in-inode
271 information) is initialized correctly. This can take place when
272 mke2fs creates the root and lost+found directory, when e2fsck creates
273 a new root inode or a new lost+found directory, and when the user uses
274 the debugfs write, mknod, or mkdir commands. Otherwise, the newly
275 create inode could inherit garbage (or old EA information) from a
276 previously deleted inode.
278 Fixed a bug in e2fsck so it would notice if a file with an extended
279 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
282 Added support to filefrag to detect files which are using the new
283 experimental file extents format, and use the non-ext2 algorithm in
284 that case. Fixed a bug to avoid reporting a false discontinuity if
285 there is one or more unallocated blocks at the beginning of a file.
287 Duplicated a check for noticing whether or not the number of blocks
288 (given a certain blocksize) is greater than 2**32 when the
289 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
290 allows mke2fs to automatically use a larger blocksize when creating a
291 filesystem on a very large device when run on systems that do not
292 support BLKGETSIZE64.
294 Fix the I18N build which was broken in e2fsprogs 1.36 because the
295 build system had been switched to treat the .gmo files as shipped
296 files (for backwards compatibility with systems that have older GNU
297 I18N tools installed), but the gen_tarball.in script was still
298 removing the .gmo files from the official source distribution.
300 Fixed various Debian packaging issues --- see debian/changelog for
301 details. (Addresses Debian Bugs ##296769, #299341)
306 Added new functions to the e2p library which convert between a string
307 and os_type: e2p_os2string() and e2p_string2os(), and used them to
308 make the generated binaries more compact.
310 Fixed a compile-time error on Darwin systems.
312 Cleaned up the lib/ext2fs Makefile slightly.
315 E2fsprogs 1.36 (February 4, 2005)
316 =================================
318 All of the patches that were applied to Fedore Core 3's
319 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
320 lot of bug fixes first. Users of Fedora Core 3 are strongly
321 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
323 Add support for filesystem with the online resizing via resize inode
324 feature. Fixed numerous bugs from the Fedora patches. The Fedora
325 patches also didn't bother to do any consistency checking on the
326 resize inode, or add any tests to the regression test suite. The "-R
327 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
328 being listed in mke2fs's usage message. All of these shortcomings
331 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
332 program. In order to do this, the user must run the commands:
334 debugfs -w /dev/hdXXX -R "features ^resize_inode"
337 Optionally, the ext2prepare command can be used to re-enable online
338 resizing after the filesystem has been fixed.
340 The fsck program will now accept an optional filedescriptor argument
341 to the -C option. (The Fedora version of this patch would sometimes
342 cause fsck to ignore a parameter on fsck's command line in some rare
345 Make sure e2fsprogs doesn't write garbage into the reserved portion of
348 Make sure resize2fs releases the blocks belonging to the old inode
349 table blocks when moving the inode table. (Addresses Debian Bug:
352 Skip the r_resize_inode test if resize2fs is not compiled (due to
353 configure --disable-resizer)
355 E2fsck now checks the summary filesystem accounting information, and
356 if any of the information is obviously wrong, it will force a full
357 filesystem check. (Addresses Debian Bug #291571)
359 Fix e2fsck to not complain when the resize_inode feature is enabled,
360 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
363 Fix e2fsck to note delete symlinks that contain an extended attribute
364 after the ext_attr feature flag has been cleared. (Addresses Red Hat
367 Add new utility program, copy_sparse.c, which is very useful
368 for dealing with large sparse files (such as e2image files).
370 Add support for jnl_blocks[] for debugfs's set_super_value.
372 Fix filefrag so that it works correctly with sparse files.
374 Filefrag -v will print first and last blocks.
376 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
379 Add mke2fs support so that it can support filesystems larger than 4TB
380 automatically, by retrying with a 4k blocksize if the device size is
381 too big to be expressed using a 1k blocksize. (Addresses Sourceforge
384 Change blkid to test for NTFS first because Windows sometimes doesn't
385 clear enough of the parition to confuse the probing routines into
386 thinking the old filesystem type is still valid. (Addresses Debian
389 Add support for swap partition label and uuid's in the blkid library.
391 Add support to the blkid library to recognize Oracle ASM volumes.
393 Make blkid -t display all devices that match the specified criteria,
394 not just the first one, and work more consistently when the blkid
395 cache file is not available or set to /dev/null. (Addresses Debian
396 Bug #290530 and #292425)
398 Badblocks will now correctly display block numbers greater than
399 999,999,999 in its progress display.
401 The tune2fs program will not allow the user from setting a ridiculous
402 number of reserved blocks which would cause e2fsck to assume the
403 superblock was corrupt. E2fsck's standards for what is a ridiculous
404 number of reserved block has also been relaxed to 50% of the blocks in
407 The blkid library will return vfat in preference to msdos, and ext3 in
408 preference to ext2 (if the journalling flag is set) so that mount will
409 do the right thing. (Addresses Debian bug #287455)
411 Mke2fs will now use the -E option for extended options; the old -R
412 (raid options) option is still accepted for backwards compatibility.
413 Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
415 Mke2fs will now accept a size in megabytes, gigabytes, and other units
416 (via "32m" or "4g" on the command line) if the user finds this more
417 convenient than specifying a block count.
419 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
420 cache conherency problem.
422 Debugfs now supports a new command, set_inode_field, which allows a
423 user to manually set a specific inode field more conveniently, as well
424 as set entries in the indirect block map.
426 Debugfs's set_super_value command has been enhanced so that the user
427 can set most superblock fields, including the date/time fields and
428 some of the more newsly added superblock fields.
430 E2fsprogs programs now accept an offset to be passed to the file
431 specifiers, via the syntax: "/tmp/test.img?offset=1024".
433 E2fsprogs programs will now accept blocksizes up to 65536; kernel
434 support on the x86 doesn't exist for now, but it can be useful on
435 other architectures with page sizes greater than 4k. There are 2.6
436 kernel patches out there which enable this, but they are of this
437 writing still experimental.
439 The e2image command now takes the -s option which will scramble
440 directory entries for raw image files.
442 Fix a file descriptor leak in the filefrag program.
444 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
447 Fix bug in debugfs where kill_file would lead to errors when deleting
448 devices and symlinks. (Sourceforge Bugs #954741 and #957244)
450 Fix bug in the blkid library when detecting the ocfs1 filesystem
452 Remove obsolete EVMS 1.x and a.out DLL support.
454 E2fsck will attempt to recover from a journal containing illegal blocks.
456 Fixed two potential ordering constraint problems in e2fsck which might
457 cause the filesystem to be corrupted if e2fsck is interrupted during a
458 (extremely narrow) race window. Thanks to Junfeng Yang from the
459 Stanford Metacompilation group for pointing this out.
461 Fixed bug in e2fsck where it would not accurately detect whether or
462 not the system is running on adaptor if the ACPI device representing
463 the AC adapter didn't correspond to the what was used on IBM
466 Change e2fsck to accept directories greater than 32MB.
468 Fix e2fsck so that a checkinterval of zero disables a time-based check
471 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
472 to the PAGER environment variable. (Addresses Debian Bug #239547)
474 Tune2fs will not mark rewrite the superblock if the feature bitmasks
477 The debugfs program will set the filetype information when creating a
480 Add debugfs -d option to use a separate source of data blocks when
481 reading from an e2image file.
483 Add e2image -I option which allows the e2image metadata to be
484 installed into a filesystem.
486 Fixed bug in the badblocks program which caused "done" to always
487 appear in english even when a translation was available. (Addresses
490 The blkid program has a new option -o which controls the output format
491 of the blkid program; this is makes blkid more convenient to use in
494 Fix a minor bug in uuid library, which was not using the full 14 bits
495 of clock sequence when generating UUID's.
497 Fix a Y8.8888K problem in the uuid library.
499 Logsave now creates a new session id for itself to avoid getting
500 killed by init whan transitioning between init levels.
502 Change the licensing of the UUID library to be the 3-clause BSD-style
503 license; this allows Apple to use the uuid library in Darwin.
505 Add ocfs and ocfs2 probe support into the blkid library.
507 Fix a memory and file descriptor leak in the blkid library.
509 The blkid library will revalidate the device if the system time is
510 earlier than last verification time of the device, since that
511 indicates that the system time is probably nottrustworthy.
513 The blkid library will override the default location of the blkid.tab
514 file by the BLKID_FILE environment variable, if it is available.
516 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
518 Add various portability fixes for lame new versions of glibc, Darwin
519 and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
520 Bugs #239934, #264630, #269044, #255589, #289133)
522 Add support for Windows 9x/NT under Cygwin.
524 Updated and clarified various man pages. (Addresses Debian Bugs #236383,
525 #241940, #238741, #242995, #256669, #268148, #256760, #273679)
527 Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
529 Update the rpm spec files so that it works better with Fedora core 2
532 Fixed various Debian packaging issues (see debian/changelog). In
533 particular, fixed the Debian initrd scripts. (#241183, #248050,
540 Fixed various gcc -Wall warnings.
542 The uuid library now has new functions uuid_unparse_upper() and
543 uuid_unparse_lower() which forces the case of the hex digits to be
544 upper case, or lower case.
546 The build process has been speeded up by enhancing the subst program
547 to update the modtime on the generated files even when the generated
550 The uuid library now uses C99 stdint.h types instead of custom types.
552 Updated config.guess and config.sub with newer versions from the FSF.
554 Removed out of date .cvsignore files from the source distribution.
556 The ext2fs_unlink() function will return an error if both the name and
557 inode number are unspecified, to avoid doing something surprising
558 (such as unconditionally deleting the first directory entry).
559 Directory entries are now deleted by coalescing them with the previous
560 directory entry if possible, to avoid directory fragmentation. This
561 is not an issue with the e2fsprogs suite, but may be a problem for
562 some of the users of libext2fs, such as e2tools.
564 Add support for version numbers of the form "1.36-rc1".
566 Fix build of mke2fs.static.
568 Add basic ext2fs library support for large (EA in inode) inodes.
570 The test_io mechanism can now abort after n reads or writes to a
571 particular block. The block is specified by TEST_IO_BLOCK environment
572 variable, and the read/write count by the TEST_IO_READ_ABORT and
573 TEST_IO_WRITE_ABORT environment variables. The block data is now only
574 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
576 UUID_DEFINE() in the uuid library now creates a static variable, with
577 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
578 be used in header files.
580 Add support for the install-strip and install-shlibs-strip targets, as
581 suggested by the GNU coding guielines. "make install" no longer
582 strips the binaries which are installed.
584 Remove support for the --enable-old-bitops configure option which was
585 only for very old sparc systems.
587 Remove support for --enable-clear-htree; this was only needed during
588 the early development of the htree patch.
590 Use Linux-kernel-style makefile output so it is easier to see compiler
593 Update gettext files to version 0.14.1.
595 Update to use autoconf 2.5x.
597 Improved support for compiling e2fsprogs under dietlibc.
599 Make e2fsprogs portable to Solaris and FreeBSD systems.
601 Add blkid_verify(), blkid_get_library_version(), and
602 blkid_parse_version_string() functions to the blkid library.
604 Add pkg-config files for e2fsprogs's libraries.
606 Fix "make uninstall" to so that it removes everything that is installed.
608 Add a configure --enable-maintainer-mode option which enables the
609 makefile rules to rebuild the configure script from configure.in, and
610 to reubuild the .gmo files in po directory.
612 Drop the sparc assembly bitwise operations; it's less efficient
613 than the GCC 3.4 compile code and triggers compiler warnings on
614 sparc64. Thanks to Matthias Andree for his analysis and suggestions.
615 (Addresses Debian Bug #232326)
618 E2fsprogs 1.35 (February 28, 2004)
619 ==================================
621 E2fsck has a new -k option, which in conjunction with the -c options,
622 preserves the existing badblocks list.
624 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
626 E2fsprogs will now deal correctly with symlinks that contain
627 extended attribute information, which can be created using SE Linux.
628 (Addresses Debian Bug #232328)
630 Remove a double longjump into an invalid stack frame bug in e2fsck.
631 (This was during an abort sequence, which normally worked on Linux and
632 caused a core dump on other operating systems.)
634 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
635 (the NLS library will replace "" with the .po header information).
637 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
638 dump due to a division by zero error. (Addresses Debian bug #207082)
640 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
641 when reconnecting a directory requires creating a lost+found
642 directory. (Addresses Debian bug #219640).
644 Fixed a bug where e2fsck would bomb out if a journal needed to be
645 replayed when using an alternate superblock.
647 E2fsck will give an extra grace period before actually forcing a check
648 if the laptop is running on battery. The next time fsck runs while
649 the system is on the AC mains, or after the grace period is exceeded,
650 the filesystem will be checked. (Addresses Debian bug #205177)
652 E2fsck will inform the user when there are 5 or fewer mounts before a
653 filesystem check will be forced. (Addresses Debian bug #157194)
655 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
656 We now correctly handle the case where there is an overlap between a
657 block group descriptor or a superblock and a bad block indirect block.
658 In the case where the indirect block is corrupted, we now suggest
661 Fix byte swap bugs in e2fsck that caused the journal backup location
662 in the superblock and symlinks created by SE Linux to be cleared
663 by e2fsck on big-endian machines. (Addresses Debian bug #228723)
665 E2fsck -c now replaces the current list of bad blocks with the ones
668 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
669 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
671 Fix a potential bug in e2fsck which could cause it to core dump when
672 trying to print the location of the backup superblock.
674 Protect against a potential core dump in e2fsck when printing a
675 message about backup superblocks.
677 Add support for backing up the journal inode location in the
678 superblock. E2fsck will automatically save the journal information in
679 the superblock if it is not there already, and will use it if the
680 journal inode appears to be corrupted. ext2fs_add_journal_inode()
681 will also save the backup information, so that new filesystems created
682 by mke2fs and filesystems that have journals added via tune2fs will
683 also have journal location written to the superblock as well.
684 Debugfs's logdump command has been enhanced so that it can use the
685 journal information in the superblock.
687 E2fsck will now update all superblocks when moving the journal inode.
689 Shrink the size of the e2fsck executable by moving some initialized
690 variables to the BSS segment.
692 E2fsck will avoid printing the ^A and ^B characters which bracket the
693 progress bar when stdout and stdin are a tty device instead of a pipe
694 to another program. (Addresses Debian bug #204137)
696 Debugfs's mkdir command will automatically expand the directory if
697 necessary. (Addresses Debian Bug: #217892)
699 Fixed a bug in debugfs so that copying a file from /dev/null uses the
700 correct mode bits. (Addresses Debian Bug: #217456)
702 If the environment variables DEBUFS_PAGER and PAGER are not set,
703 debugfs now searches for the appropriate pager to use, beginning with
704 /usr/bin/pager, and then falling back to 'more' and 'less'.
705 (Addresses Debian bug #221977)
707 Debugfs will now support 2.6 device numbers where the major or minor
708 number may be larger than 255. (Addresses Sourceforge bug #865289)
710 Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
712 Chattr now stops processing options when it sees '--'. (Addresses
715 Fix regression tests so they work correctly when e2fsprogs is compiled
716 with configure --disable-htree.
718 Fix bug in uuid library when there is no network card and the library
719 is generating a time-based uuid. The random MAC address was not
720 correctly generated to be a multicast address.
722 Add compile_et extensions from Heimdall that were missed the first time
725 Fix bug in badblocks when using O_DIRECT; we need to make sure that
726 we're reading from an offset which is page aligned. For read-only and
727 read-write tests, we try to recover after an error so that we can
728 continue reading on page-aligned boundaries. (Addresses Debian Bug
731 Badblocks now checks 64 blocks at a time instead of 16. (Addresses
734 Updated and clarified various man pages. (Addresses Debian Bug
735 #206845, #222606, #214920, #232406)
737 Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
739 Fixed various Debian packaging issues (see debian/changelog).
744 Fixed a build problem so that e2fsprogs would compile with the
745 --enable-profile option to configure selected. (Addresses Sourceforge
748 Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
749 Bugzilla Bug #112448)
751 Centralize code which calculates the location of the superblock
752 and block group descriptors so that it is in a single library routine.
754 Added two new functions, ext2fs_file_open2() and
755 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
757 Fix compile_et to output the correct prototype for
758 initialize_xxx_err_table_r() in the header file. (Addresses Debian
761 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
763 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
764 present. This is for when we try stuffing an int into void * pointer.
766 Fix type-punning which can cause gcc 3.x to miscompile code by getting
767 confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
768 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
769 **'. The EVMS code uses an ugly union approach since we don't want to
770 modify the EVMS interfaces.
772 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
773 aid build process on systems can use invoke GNU make as "gmake".
775 Added regression testing for mke2fs.
777 Fixed gcc -Wall nitpicks.
779 Fixed various compiler warnings.
781 Add portability fixes for FreeBSD and for using fsctl under Darwin to
782 support ext2 ioctl's.
785 E2fsprogs 1.34 (July 25, 2003)
786 ===============================
788 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
789 a tight loop while waiting for a child fsck to exit in some cases.
790 This burns CPU times which slows down the low-level filesystem check.
792 Added code to mke2fs to assure that the default block size for a
793 filesystem is at least as big as the sector size of the device, if it
796 Changed mke2fs and resize2fs to round the default size of a filesystem
797 to be an even multiple of the VM pagesize in order to avoid a Linux
798 kernel bug introduced when the storage of the buffer cache was moved
801 Mke2fs will warn the user when creating a filesystem with journaling
802 and a blocksize greater than 4096. (Addresses Debian bug #193773)
804 Fixed a bug in resize2fs which caused it to fail on filesystems with a
805 non-empty bad block list. Resize2fs now discards any blocks on the
806 badblock list which are no longer part of the filesystem as the result
807 of a filesystem shrink. (Note: this means that shrinking and then
808 enlarging a filesystem is no longer a reversible operation;
809 information about bad blocks in the part of the filesystem which is to
810 be chopped off will be lost.)
812 Changed resize2fs so the user can use prefixes to specify the units of
813 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
814 and to make the error and informational messages explicitly display
815 the blocksize used by the filesystem, in order to avoid confusion.
816 (Addresses Debian bug: #189814)
818 Added a new debugfs command, dump_unused, which dumps the contents of
819 all unused blocks to stdout. (Useful as an emergency try-to-find
820 deleted data command.)
822 Added a new debugfs command, imap, which prints the location of a
823 specified inode in the inode table.
825 Fixed a bug in the badblocks program which caused it to use one bit of
826 randomness in its non-destructive read/write test, instead of using a
827 full 8 bits of randomness.
829 Added a new option (-t) to badblocks, which allows the user to control
830 the test pattern(s) used when checking a disk.
832 The blkid probe function now more correctly detects UDF filesystems.
834 Fixed a bug in the blkid library which caused it to not update its
835 cache if a filesystem changes from having a label to not having a
838 Fixed a bug in the blkid library wihch could avoid an infinite loop
839 in blkid_find_dev_with_tag() if /proc is not mounted and there the
840 /etc/blkid.tab file has not yet been created.
842 Fixed the badblocks program so that the destructive read/write test
843 honors the -c option, and to use O_DIRECT when possible to avoid
844 thrashing the system block buffer cache.
846 Fixed various NLS issues.
847 - Added Czech and Swedish translations
848 - Removed testing NYC translation
849 - Fixed NLS support for message abbrevations in e2fsck
850 - Remove de-utf.po, since we shouldn't have two versions using different
852 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
853 simplify the statistics reporting in e2fsck.
855 Changed configure.in so that its defaults for *BSD systems no longer
856 build an fsck wrapper, and not to install in /usr/local by default.
858 Fixed some minor spelling errors/typo's in e2fsck and the configure
861 Fixed various Debian packaging issues (see debian/changelog).
863 Updated and clarified man pages. (Addresses Debian Bug #195616)
868 Fix gcc -Wall nitpicks.
870 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
871 NLS support by default. (Added partial workaround for gettext/Darwin
872 incompatibility problems.)
874 Added full MIT KRB5 and Himdall compaibility support to the com_err
875 library and the compile_et program. (Addresses Debian bug #191900)
877 Added the blkid_known_fstype() function to the blkid library, which
878 returns true if it is passed a filesystem type which is recognized by
879 the blkid probing functions.
881 Improved the documentation for the blkid library.
883 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
884 returns the hardware sector size of a device, if it is available.
886 Added a dependency in the blkid library's .so file to the uuid
887 library, since the former uses the latter. (Addresses Debian bug
890 Added --with-diet-libc and --disable-evms to the configure script.
892 Fixed a minor memory leak in the badblocks program.
894 Fixed a portability problem in tune2fs --- not all systems have strptime().
896 Fixed a portability problem in debugfs with the use of getopt() more
897 than once. Old-style BSD, new-style BSD, and Linux C libraries all do
900 Add support Windows support to ext2fs_get_device_size().
902 Added (normally disabled) debugging code to the Unix I/O manager which
903 causes it to disable all userspace caching if the NO_IO_CACHE is
906 Changed the test I/O manager so it can always be linked into e2fsck,
907 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
908 configure script. The test I/O manager will only print any debugging
909 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
910 variables are set, which specifies which I/O operations are logged and
911 a block number to watch, respectively. The log messages are sent to
912 stderr by default, unless a filename is specified via the
913 TEST_IO_LOGFILE environment variable.
916 E2fsprogs 1.33 (April 21, 2003)
917 ===============================
919 Added a new utility program, logsave, which captures the output of a
920 command in a log file, even if the containing directory hasn't been
921 mounted yet (in which case the it saves the output in memory until it
922 can write out the logfile). This is useful for capturing the
923 output of fsck during the boot sequence.
925 Fixed some portability problems that were causing problems under
926 the Cygwin32 environment.
928 Mke2fs now interprets a negative number to the -b option as a minimum
931 Fixed a bug in mke2fs which was incorrectly checking the argument to
932 the -g option if the default block size was used. (Addresses Debian
935 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
936 it can not find filesystem checkers for jfs, reseirfs, and xfs.
938 E2fsck now updates the global free block and inode counters from the
939 block group specific counters quietly. This is needed for an
940 experimental patch which eliminates locking the entire filesystem when
941 allocating blocks or inodes; if the filesystem is not unmounted
942 cleanly, the global counts may not be accurate.
944 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
945 2.0 is not yet supported; this only pulled in the bug fixes: fixed
946 possible hangs caused by bugs in calling waitpid, and not setting the
947 pipe to non-blocking mode; also fixed a file descriptor leak; made
948 sure all functions call log entry/exit functions.)
950 Badblocks now flushes its output file as bad blocks are discovered.
952 The uuid library is now more paranoid about assuming the correctness
953 of the /dev/random device; it mixes in a stream of bytes from
954 random/srandom, just in case.
956 Update Debian files to reflect the fact that I am now the Debian
957 maintainer of e2fsprogs. Other various Debian-specific packaging
960 Move the source tarball generation functions from the top-level
961 makefile to the util/gen-tarball script.
963 Updated the Turkish .po translation file.
965 Added Heimdal and MIT krb5 extensions to the com_err library to make
966 it more compatible with com_err libraries from those distributions.
968 Changed dumpe2fs to always display the superblock fields relating to
969 the journalling and/or directory indexing feature even if those
970 features are not enabled.
972 Updated and clarify copyright statement vis-a-vis alpha releases of
975 The ss library will now try to dynamically link to the readline
976 library and use it if it is present in the system. This means that
977 the debugfs program now has line editing and history features. The
978 SS_READLINE_PATH environment variable is used to find a readline or
979 readline-compatible library.
981 E2fsck now finds most duplicate filenames (all when rebuilding all
982 directories via the -D option) and offers to delete or rename
983 duplicate filenames/directory entries. (Addresses Debian Bug #176814).
985 Fix bug in e2image. When writing out a raw image file, include data
986 blocks from symlinks that do not store the symlink within the inode.
988 Fix bug in resize2fs which incorrectly moved the block and inode
989 bitmaps for sparse superblock filesystems and incorrectly marked
990 blocks as in use. (Addresses Debian bug #174766)
992 Added a new shared library, the blkid library, which efficiently
993 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
994 and UUID filesystem specifiers without needing to search all of the
995 devices in the system. Instead, the device is looked up in a cache
996 file, and then verified to make sure the blkid cache is correct.
998 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
999 the device name, using the blkid library. (Addresses Debian bugs
1002 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
1003 used for spaces in device labels.
1005 Removed 32-bit limitations for debugfs's dump command.
1007 If the user specifies a large number of inodes, Mke2fs will
1008 automatically adjust the number of blocks per group to find a valid
1009 set of filesystem parameters.
1011 Add workaround to detect broken MD devices where when some of the
1012 underlying devices are marked read-only, writes to the MD device are
1013 silently dropped. E2fsck will detect if there is an attempt to run
1014 the journal twice, and abort with an error if this is the case.
1015 (Addresses IBM Bugzilla bug #1226)
1017 E2fsck will print an error if more than one of the -p/-a, -n or -y
1018 options are specified.
1020 E2fsck will fix HTREE corruptions in preen mode, without stopping the
1021 boot process. This is needed because the 2.4 ext2 filesystem
1022 accidentally had the INDEX_FL backwards compatibility code removed.
1024 Mke2fs no longer creates filesystems with the dir_index flag set by
1025 default; the user has to specifically request it.
1027 Update and clarified various man pages. (Addresses Debian bugs
1028 #173612, #175233, #175113, and #170497, #185945, #188318)
1030 Created man page for the mk_cmds program (from the libss library).
1035 Fix various gcc -Wall nits.
1037 Fixed a lot of portability problems that caused e2fsprogs not to build
1038 successfully under Solaris and Apple/Darwin.
1040 Fixed a Makefile dependency to allow building e2fsprogs using parallel
1043 Changes to create a subset distribution which consists only of the
1044 et, ss, uuid, and blkid libraries. The configure script and top-level
1045 makefile were changed to support working with a subset distribution.
1047 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
1048 actually used, and might people who are looking for
1049 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
1051 Updated debian files to fix a number of Lintian warnings.
1053 Updated config.guess and config.sub with newer versions from the FSF.
1055 Removed unnecessary libraries from being linked into the fsck, lsattr,
1056 chattr, and blkid executables.
1058 E2fsprogs 1.32 (Nomvember 9, 2002)
1059 ==================================
1061 Fixed a bug in the Unix I/O routines which caused needless writebacks
1062 of clean blocks from the unix_io cache (they were erroneously marked
1063 as being dirty, so they were getting written back to disk before
1064 getting evicted from the disk cache). This was harmless, but it
1065 significantly slowed down e2fsck.
1067 Made some other minor optimizations to the Unix I/O routines to save a
1068 small amount of CPU time.
1070 Updated internationalization files.
1073 E2fsprogs 1.31 (Nomvember 8, 2002)
1074 ==================================
1076 Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
1077 compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
1078 handling for child process that die unexpectly. Add a hack to force
1079 mkfs to create filesystems that won't cause problems with hardware
1080 that has 2k or 4k minimum blocksize requirements. Read from child
1081 processes in non-blocking mode, so that the GUI continues to update.
1083 Fix e2fsck so that it returns the appropriate exit code when the root
1084 filesystem has been changed, so that system's rc scripts will be told that
1085 the system needs to be rebooted.
1087 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
1088 was set, some of the descriptor blocks that should have been written
1089 out were getting skipped.
1091 Changed e2fsck to force out changes to the backup copies of the
1092 superblock and block group descriptors when important changes are made
1093 to those data structures.
1095 Fix a bug where e2fsck could erroneously mark a filesystem as being
1096 clean if a check of dirty filesystem is interrupted with a ^C. (Bug
1097 introduced in e2fsprogs 1.28.)
1099 If journal debuging is enabled using --enable-jbd-debug, the debugging
1100 level is now set via the E2FSCK_JBD_DEBUG environment variable.
1102 If byteswapping support is disabled using configure --disable-swapfs,
1103 skip the tests which depend on byte-swapping, so that "make check"
1106 Lshattr will now display the indexed directory flag. Also, some of
1107 the more esoteric compression flags are supressed unless compression
1108 support has been enabled.
1113 E2fsprogs 1.30 (October 31, 2002)
1114 =================================
1116 When resizing a filesystem, and inodes need to moved, resize2fs will
1117 update the inode's ctime field, and the mtime field of the containing
1118 directories, so that incremental backups using dump/restore will work
1121 In order to avoid spurious errors, e2fsck wil check the last
1122 superblock write time to determine whether or not it can safely use
1123 the LOW_DTIME checks to determine if there are inodes on the orphan
1124 inode linked list that had somehow gotten disconnected. (Addresses
1125 Sourceforge bug #620980)
1127 Partition in /proc/partitions that being with the string "lvm" are
1128 considered real partitions even if they do not end with a number.
1130 Fixed a bug in the the uuid generation function, where if /dev/urandom
1131 is not present, but /dev/random is, and there isn't sufficient
1132 entropy, the get_random_byte function could spin a loop forever.
1134 E2fsck, mke2fs, etc. will now reliably notice when image files are
1135 mounted using the loopback interface. (Addresses Sourceforge bug
1138 When flushing buffers (as is done by badblocks, for example) check to
1139 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
1140 FDFLUSH ioctl which causes the MD device driver which causes confusing
1141 syslog messages about obselete ioctl messages. (Addresses Sourceforge
1144 Debugfs's write command now checks to see if the destination filename
1145 exists before creating it. (Addresses Sourceforge bug #478195.)
1147 When installing man pages, search for compressed man pages using all
1148 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
1150 Fixed a bug in fsck where multiple filesystems specified on the
1151 command were not being checked in parallel due to a logic bug
1152 introduced to support the FSCK_MAX_INST environment variable.
1154 We have added a new superblock field, s_mkfs_time, which indicates
1155 when a filesystem was created. It is set via mke2fs, and printed out
1156 by dumpe2fs, but is not actually touched by the kernel.
1158 Dumpe2fs has been made more robust by not aborting if there is an
1159 error reading the block/inode bitmaps; instead it will still print out
1160 the location of the block/inode bitmaps and inode table.
1162 Add support for the an alternative block group descriptor layout which
1163 allows for on-line resizing without needing to prepare the filesystem
1164 in advance. (This is the incomat feature flag meta_bg.)
1166 Add support for storing default mount options in the superblock, so
1167 that the filesystem can be mounted with specific mount options without
1168 needing to specify them on the mount command line or in the /etc/fstab
1171 Add support for a new inode flag, which is to be used for indicating
1172 the top of directory hierarchies for the Orlov block allocator.
1174 Fix e2fsck so that if it creates the lost+found directory, it does so
1175 with the more apporpriate permissions of 0700. Also change
1176 mklost+found so that it also creates the directory 0700.
1178 Fixed format bug in e2fsck if NLS is in use.
1180 Add a German translation for e2fsprogs's NLS support.
1182 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
1183 the beginning of the inode table. This won't matter much, since if
1184 there is a bad block at the beginning of the inode table, the root
1185 directory won't be available. But at least e2fsck won't crash in this
1188 Fixed endian problems in the htree code for e2fsck and debugfs.
1190 When byte-swapping a filesystem on a PPC architecture, byte-swap the
1191 bitmaps since the historical big-endian ext2 variant had byte-swapped
1192 bitmaps, and the ext2fs library assumes this. This fixes the
1193 regression test suite on PPC machines.
1195 Fix e2image so that it handles a bad block in the inode table
1198 E2fsck now uses a more sophisticated algorithm to salvage corrupted
1199 directories that recovers more information in the corrupted directory
1202 E2fsck now performs additional consistency checks on indexed (HTREE)
1205 Fix bug where efsck might get confused about whether a completely
1206 empty directory block is an empty leaf block or an interior htree
1207 node. This could cause e2fsck to get confused into think that a valid
1208 indexed directory was corrupted.
1210 E2fsck no longer creates an empty directory entry at the end of a
1211 directory block when optimizing a directory. This would cause some
1212 earlier versions of the dxdir kernel code to corrupt the directory
1213 when attempting to split a node containing an empty directory entry.
1215 E2fsck could sometimes in rare circumstances leave the indexed flag
1216 set after a small directory was optimized by compressing it instead of
1217 indexing it. (This should never happen in real life, since
1218 directories that small wouldn't have been indexed, but better safe
1221 E2fsck now only updates the master superblock in all cases. This
1222 slightly shortens its run time.
1224 Ext2ed can deal with directory entries of length 0; previously it
1225 would get stuck in an infinite loop.
1227 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
1228 specifiers. (Sourceforge patch #613447)
1230 Badblocks will now work correctly on read-only devices such as
1231 CD-ROM's. (Sourceforge patch #600451)
1233 Updated and clarified man pages. (Addresses Debian bug #167108)
1236 E2fsprogs 1.29 (September 24, 2002)
1237 ===================================
1239 Fixed a bug in e2fsck which could corrupt a directory when optimizing
1240 it (via the -D option) or rebuiliding the hash tree index with a 1 in
1241 512 probability, due to a fence post error.
1243 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
1246 Mke2fs now enables the directory indexing flag by default. (Since
1247 this is a compatible feature flag, it's safe to do so.)
1249 Tune2fs will support setting the directory indexing feature flag. It
1250 will automatically set up the default hash algorithm and hash seed
1251 fields in the superblock.
1253 If the bone-headed user enters the root filesystem twice in
1254 /etc/fstab, the -R option which skips the root filesystem will skip
1255 all of them. (Addresses Debian bug #159423). Note! This is not a
1256 precedent for dealing intelligently with any other kind of doubled
1257 entry in /etc/fstab!
1263 Removed perror declaration in lib/et/internal.h. All modern systems
1264 can be expected to define perror() these days. Besides, the lib/et
1265 code wasn't using perror at all anyway. :-)
1268 E2fsprogs 1.28 (August 31, 2002)
1269 ================================
1271 Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
1272 for setting the htree flag is not included yet, although it can be
1273 manually turned on via the debugfs program.
1275 Clarified e2fsck error message which is printed when it cannot find
1276 sufficient contiguous block when relcating filesystem metadata.
1278 Added support for building an EVMS plugin module for ext2/3. This
1279 module is substantially the same as the EVMS module shipping with EVMS
1280 1.1, with one or two bugfixes. E2fsprogs can also build this plugin
1281 for use with EVMS 1.0 (which did not include the ext2 plugin module),
1282 if the configure --enable-old-evms flag is given.
1284 Fsck will search through EVMS volumes when trying to resolve
1285 filesystem specifications such as LABEL=xxx or UUID=xxx.
1287 Added a new utility program, /sbin/findfs, which will return
1288 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
1291 Update and clarified various man pages. (addresses Debian Bug #145044,
1292 #146437, #131350, #151990, #144621, #141938)
1294 If there are no filesystems specified on fsck's command line, fsck now
1295 treat that as if the -As options were given. Previously it would
1296 simply do nothing. (Addresses Debian Bug #153102)
1298 Mke2fs no longer treats a failure to be able to clear the MD signature
1299 at the end of the filesystem as a fatal error. (Addresses Debian Bug
1302 The e2p library functions (which are used by lsattr and chattr) now
1303 double check to make sure the file is a regular file or directory
1304 before attempting to use the ext2 ioctls. Some device drivers
1305 unfortunately respond to the ext2 ioctl's with unknown behaviour.
1306 (Addresses Debian Bug #152029).
1308 The extended attribute handling has been updated to correspond with
1309 the latest V2 bestbits ACL code.
1311 Fixed bug in e2fsck which caused it to not clear the dtime field when
1312 processing truncated inodes on the orphan list. This could cause data
1313 loss(!) if a filesystem is rebooted before a truncate has been
1316 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
1317 algorithms. This makes e2fsck much faster in the case of severely
1318 corrupted filesystems where a large number of blocks are claimed by a
1319 large number of inodes. (Thanks to the 2.5 IDE device driver for
1320 inspiring this work.)
1322 Resize2fs has been significantly sped up when shrinking and expanding
1323 a filesystem by a very small number of blocks (for example, when EVMS
1324 is converting a partition to be an EVMS legacy volume).
1326 Added a new option to e2fsck, -D, which will optimize or compress all
1327 of the directories in the filesystem.
1329 E2fsck now catches SIGINT and SIGTERM to make sure it will can
1330 properly clean up and only exit at safe points. Fsck will pass
1331 SIGINT/SIGTERM to its child processes, and wait until they have all
1332 exited before it exits.
1334 The uuid parsing code in the uuid library now properly complains when
1335 an illegally formated uuid is presented to it. (Addresses Debian bug
1338 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
1339 and 2.4.17, since the workaround can cause problems when using a 2.4
1340 kernel with an old version of glibc built with the 2.2 headers.
1342 Fixed a bug in mke2fs where it wasn't properly clearing the initial
1343 superblock used by other filesystems. (Addresses Debian bug #147256.)
1345 Added support for the synchronous directory feature written by Andrew
1348 The debugfs program can delete directories using the rmdir command.
1350 Add support for 8k and 16k filesystems (for systems with page sizes
1351 that are greater or equal to 8k or 16k, respectively). Note that
1352 these filesystems can not be mounted on x86 systems, or other systems
1353 with only 4k page sizes, due to limitations in the current Linux VM
1356 Resize2fs requires that the filesystem state be valid and have no
1357 errors; otherwise, e2fsck -f must be run first. (Previously it simply
1358 required that the last fsck time be greater than the last mount time.)
1360 Configure now defaults the man pages directory to /usr/share/man on
1363 E2fsck now offers to truncate inodes which contain too many blocks (so
1364 that i_blocks would overflow. Also fixed handling of large sparse
1367 E2fsck now more completely checks for symlink validity, including
1368 requiring NULL termination and length checks.
1370 E2fsck will offer to try forcing a disk write to remap a bad block
1371 after finding a read error when reading a filesystem metadata block.
1373 Fixed a bug in debugfs which caused the -b and -s options to crash
1374 debugfs, as well as breaking the testb, setb, and clearb functions.
1376 Added a bmap command to debugfs which calculates the logical to
1377 physical block mapping for a particular inode.
1379 Fixed a bug in code which checked to see if a device was mounted which
1380 sometimes (rarely) failed in the case of a plain file.
1382 Fixed a bug in resize2fs where when it reported an error, it would
1383 print a message erroneously indicating that the filesystem had been
1384 resized before it aborted.
1386 When resizing a plain file which is smaller than the requested size,
1387 resize2fs will attempt to extended the file so that programs like
1388 e2fsck will not complain that the file is too small.
1390 Resize2fs will print the actual new size of the filesystem when it is
1393 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
1394 information on big-endian systems.
1400 Fixed collisions with C++ reserved words.
1402 Added portability fixes for building e2fsprogs on the HURD and AIX.
1404 Added the ext2ed program for creation of test cases. (ext2ed has many
1405 limitations and bugs which make it unsuitable for production use.)
1407 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
1408 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
1409 name_len field is byte swampped on big-endian machines, since in the
1410 V2 structure, name_len is a char field which is doesn't need to be
1411 byte swapped --- except if an old-style kernel had byte-swapped the
1412 name_len field as part of the V1 structure.
1415 E2fsprogs 1.27 (March 8, 2002)
1416 ==============================
1418 The warning messages for mke2fs now go to standard error.
1420 Fixed to make sure "make check" runs all of the test programs with
1421 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
1423 The mke2fs program checks the boot sector for the BSD disk label, and
1424 avoids erasing it if it is there.
1426 Fixed a bug in e2fsck which caused it to core dump if the journal
1427 inode was missing when it was supposed to be there.
1429 E2fsck now prints ranges in pass 5 when printing deltas for the block
1432 Debugfs's "ls -l" command now will print out the file type information
1433 in the directory entry.
1435 Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
1436 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
1438 Debugfs can now examine the experimental directory indexing
1441 Fixed bug in debugfs which caused it to core dump if modify_inode is
1442 called without an open filesystem.
1444 The debugfs lsdel command now runs its output through a pager first.
1446 When installing manual pages, remove the compressed manual pages first.
1448 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
1450 Fix the 2.4 resource limitation workaround introduced in 1.26 which
1451 actually broke things on mips32, sparc32, and Alpha platforms.
1453 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
1454 (which is required by the newer libintl libraries).
1459 Fixed various gcc -Wall complaints.
1461 Fixed a few memory leaks in the e2fsck journaling code, and in the
1462 ismounted code checking for a swap device.
1464 Add new inode I/O abstraction interface which exports an inode as
1467 Exported ext2_file_flush as a public interface.
1469 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
1471 Lots of small random portability fixes to make e2fsprogs build under
1472 AIX --- even without the 5L compatibility toolkit, and even using the
1473 uber-crippled AIX native C compiler.
1476 E2fsprogs 1.26 (February 3, 2002)
1477 =================================
1479 Dumpe2fs will keep going now if the bad block inode can't be read.
1480 (Previously it stopped with a fatal error.)
1482 E2fsck will now give an opportunity to run the journal even if the
1483 recovery flag is not set. This is the default behaviour if e2fsck is
1484 using a backup superblock, since the needs_recovery flag will never be
1485 set in the backup superblock copies.
1487 E2fsck now automatically finds the backup superblock/group descriptors
1488 even when the primary superblock is completely destroyed for 2k and 4k
1489 filesystems. (Previously it just guessed/assumed that we were dealing
1490 with a 1k filesystem in that case, and users had to manually specify
1491 the backup superblock number.)
1493 Fixed a bug in e2fsck where it dereferences a null pointer when there
1494 is a problem opening a filesystem in preen mode.
1496 E2fsck now handles external journals correctly; previously it trashed
1497 the external journal device if the journal needed to be replayed.
1499 Work around ulimit incompatibility problem caused by recent 2.4
1500 kernels; the unix IO module will automatically try to set any resource
1501 limits to be infinite on startup.
1503 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1504 bitmap if it wasn't present and the blocksize was 2k or 4k.
1505 (Addresses Debian Bug #116975)
1507 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1508 clearing the new V2 fields if they do not make sense or if the ext3
1509 superblock is version 1 superblock.
1511 E2fsck will automatically relocate the ext3 journal from a visible
1512 file (i.e., /.journal) to an hidden inode if the filesystem has been
1513 opened read/write. This allows the users to add a journal while the
1514 filesystem is mounted, but the next time the system is rebooted, the
1515 journal file will disappear. This avoids problems with backups,
1516 stupid operators with superuser bits, etc.
1518 Fix a bug in fsck where it would not support a filesystem type of
1519 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1521 Fsck now supports fstab entries of the form "ext3,ext2". It will also
1522 automatically identify reiserfs filesystems.
1524 The number of processes spawned by fsck can now be limited using the
1525 FSCK_MAX_INST environment variable.
1527 Fsck now searchs the LVM proc hierarchy to find logical volumes which
1528 should be searched for UUID and label information.
1530 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1531 limit if at all possible, when opening a block device. (The filesize
1532 limit shouldn't be applied against writes to a block device.)
1534 In mke2fs and e2fsck, specifying the -c option twice will now do
1535 a read/write test on the disk. Update the man pages to encourage
1536 using the -c option, and to discouraging running badblocks separately,
1537 since users tend to forget to set the blocksize when running
1540 Mke2fs now automatically clears the immutable attribute on a
1541 pre-existing .journal file left over from a previous failed attempt to
1542 add a journal to an alreadyy-mounted filesystem.
1544 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1547 Mke2fs now creates the lost+found directory with permissions of 0700,
1548 so that files that had previously lived in protected directory are
1549 safe if they get dropped in lost+found and the system administrator
1550 doesn't deal with immediately. (Addresses Debian #bug 118443)
1552 Mke2fs and e2fsck (and all programs that use the
1553 ext2fs_check_if_mounted function) will now properly identify that a
1554 device is mounted, even in cases where devfs has confused things with
1555 multiple devices names with the same identity, or if a dim-witted
1556 system administrator has done something stupid like creating device
1557 file aliases in their home directory. Also now checks for swap devices
1558 by using /proc/swaps. (Addresses Debian bug #106622)
1560 Added a new option (-T) to tune2fs which sets the time a filesystem
1563 Speed up e2image when creating sparse raw image files by optimizing
1564 away excess lseek() system calls.
1566 Fix support of large (> 2GB) files when used as a filesystem in
1567 mke2fs, tune2fs, debugfs, and findsuper.
1569 Debugfs's stat and icheck commands now properly deals with large (>
1572 Debugfs's set_super_value command now prints out the list of valid
1573 superblock fields which can be set using the command.
1575 Debugfs's rm and kill_file command now updates the superblock free block
1576 and inode counts, thus keeping the filesystem consistent.
1578 Debugfs's lsdel command now takes an optional argument which allows
1579 the user to only see the most recently deleted files.
1581 A new command (undel) was added to debugfs which automates
1582 undeleting a deleted inode and linking it back to a directory.
1584 Debugfs's ls command now takes a new option, -d, which lists
1585 deleted directory entries.
1587 Debugfs's testb, freeb, setb, and find_free_block commands now take an
1588 optional count argument.
1590 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1591 be used to signal that a particular inode should not be eligible for
1592 tail-merging --- this is needed for programs like LILO.
1594 The findsuper (an unreleased, uninstalled utility program) has been
1595 improved to add extra validity checks and to add a progress meter.
1596 (It is still an unsupported program; the officially supported way to
1597 recover from a trashed partition table is to use gpart; findsuper is
1598 for wizards only. :-)
1600 Debugfs was fixed to compile with "configure --disable-swapfs".
1602 Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
1604 Added new translation file for Turkish.
1609 Fix general gcc -Wall complaints.
1611 E2fsprogs (mostly) works with the dietlibc.
1613 The programming texinfo file has been expanded to include description
1614 of additional libext2fs functions. (Still not compeltely done, but a
1615 lot of the more important functions have been documented.)
1617 Added a umask structure to struct_ext2_filsys, which currently only
1618 modifies the behaviour of ext2fs_mkdir(), but if we add any file
1619 creation functions to libext2fs, we should also make sure they respect
1622 The build-rpm script was fixed to be a bit more safe.
1624 The tests' Makefile now has a way of automating test case creation
1625 for e2fsck, using "make testnew".
1627 Created a new function, ext2fs_dir_iterate2 which passes more
1628 information to the callback function (identical to the one used by
1629 ext2fs_dblist_dir_iterate). The directory iterator functions take a
1630 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1631 directory entries. If the directory entry is deleted, the callback
1632 function will be called with the entry paraemter set to
1633 DIRENT_DELETED_FILE.
1635 Added new functions, ext2fs_inode_alloc_stats and
1636 ext2fs_block_alloc_stats, which takes updates block/inode allocation
1637 statistics in the bitmaps, block group descriptors, and superblock
1638 when inodes or blocks are allocated or deallocated.
1641 E2fsprogs 1.25 (September 20, 2001)
1642 ===================================
1644 This is primarily a bug-fix release; no new features were added, but
1645 there are a number of embarassing bug fixes and cleanups applied.
1647 Fix a bug mke2fs which causes stack garbage to be written to disk when
1648 zapping disk sectors. (This bug could cause mke2fs to core dump for
1649 some kernels, I suspect with security enhancement patches.)
1651 Remove unneeded #include of <linux/config.h> which was breaking
1652 building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1654 Updated tune2fs man page to reflect the fact that adding or removing a
1655 journal doesn't require running e2fsck.
1657 Remove use of AC_REQUIRE from autoconf which had been used to prevent
1658 AC_CANONICAL_HOST from being called twice; unfortunately this causes
1659 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1660 used outside of autoconf macros. Fortunately, it doesn't seem to be
1661 necessary any more, anyway.
1663 E2fsck will now not fall back to an alternate superblock if the user
1664 specifies the superblock location explicitly on the command-line.
1665 This allows easier recovery from a situation where the primary
1666 superblock and block groups are slightly corrupted, but the backup
1667 superblocks are completely broken.
1669 Fix problem which caused compile_et and mk_cmds to blow up if
1670 e2fsprogs was in a directory with a pathname that contained spaces.
1672 We are now more paranoid about checking the entry in /etc/mtab to make
1673 sure the filesystem is really mounted, since some broken distributions
1674 (read: Slackware) don't initialize /etc/mtab before checking non-root
1675 filesystems. (Slackware also doesn't check the root filesystem
1676 separately, and reboot if the root filesystem had changes applied to
1677 it, which is dangerous and broken, but there's nothing I can do about
1680 Make UUID library C++ friendly by adding appropriate extern "C"
1681 declarations and using const in the function declarations.
1683 Fix up the com_err texinfo file so that it can product a valid info
1684 file (previously, it could only be used to generate paper
1685 documentation using texinfo.tex).
1688 E2fsprogs 1.24a (September 2, 2001)
1689 ===================================
1691 Fix brown-paper bug in mke2fs which caused it to segfault when
1692 printing the version string.
1695 E2fsprogs 1.24 (August 30, 2001)
1696 ================================
1698 Revert the BLKGETSIZE64 support, since for some distributions, this
1699 ioctl has been used by an unofficial kernel patch to update the last
1700 sector on the disk, and this was causing disk corruption problems as a
1703 Mke2fs is now more careful about zapping swap space signatures and
1704 other filesystem/raid superblock magic values so that programs like
1705 mount who try to use hueristics to determine the filesystem type of a
1706 partition are less likely to be confused.
1708 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1709 regular file (since Andreas Dilger's on-line resizing tools will set
1712 Fixed some minor texinfo, man pages nits for spelling errors,
1713 texinfo warnings, etc. (Addresses Debian bug #110621.)
1715 E2fsprogs program no longer print the filesystem version number
1716 (i.e. 0.5b), since it only confuses people and doesn't serve any real
1719 E2fsck will once again compile under libc5, since it will supply its
1720 own version of strnlen if necesssary.
1722 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1723 when specifying the external journal device. tune2fs will also search
1724 devices looking for the externla journal debice when removing.
1726 E2fsprogs 1.23 (August 15, 2001)
1727 ================================
1729 Add initial support for extended attributes (EA); e2fsck will
1730 correctly handle a filesystem with EA's and check the EA blocks for
1733 E2fsck's symlink sanity checking has been cleaned up. It now checks
1734 the i_size value of fast symlinks, and checks for immutable flags
1735 being set of symlinks, etc.
1737 E2fsck now offers to clear inodes which are special files that have a
1738 non-zero i_blocks or i_size field. (The i_size field check was in the
1739 previous version of the code, but due to a bug it didn't offer to
1740 clear the inode unless i_size and i_size_high were both non-zero.)
1742 E2image can now create "raw" image files, which only contain the
1743 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1744 debugfs, etc., can be run directly on the raw image file.
1746 Add support for the 64-bit block device patches.
1748 Fixed bugs in creating external journals with a 1k blocksize.
1750 Add initial support for external journals (so long as the external
1751 journal only supports a single filesystem) in e2fsck.
1753 Remove requirement for needing to run fsck on a filesystem after
1754 removing a journal (either internal or external).
1756 The man pages now document how to create and manage external journals.
1758 Speed up the check of an ext3 filesystems by avoiding a needless flush
1759 of all of the superblock and block group descriptors.
1761 Speed up creating an internal journal using tune2fs in the case where
1762 the filesystem has a lot blocks already allocated.
1764 Tune2fs has been fixed to make sure that only error messages go to
1765 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1767 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
1768 now not set the sparse_super feature. (Addresses Debian bug #108165)
1770 Add support in fsck for the filesystem type "auto".
1772 Fsck -A will not try to interpret device names for filesystems which
1773 have a pass number is 0. (Addresses Debian bug #106696).
1775 Fsck prints a warning message if now valid filesystems are passed to
1776 it. (Addresses Debian Bug #107458.)
1778 E2fsck now gives an explicit warning if there filesystem still has
1779 errors at the end of the run. (Addresses Debian bug #104502)
1781 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
1782 reflects an error. E2fsck will also not run the orphan list if the
1783 filesystem contains errors, since the orphan list might be corrupted.
1785 E2fsck now prints the number of large files when given the -v option.
1787 Fixed minor memory leaks in e2fsck.
1789 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
1792 E2fsprogs 1.22 (June 22, 2001)
1793 ==============================
1795 Fixed a bug in e2fsck's handling of orphan inodes which are special
1796 files (i.e., block/character device files, named FIFO's, etc.).
1798 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1799 tune2fs to fail at adding a journal to a mounted filesystem.
1801 Fixed a few big-endian bugs in e2fsprogs
1802 * The directory block functions were accidentally reporting
1803 some directories as corrupted when they weren't.
1804 * If e2fsprogs is compiled --disable-swapfs, the C language
1805 equivalents weren't being included for big-endian platforms.
1806 (Fixes Debian bug #101686).
1808 Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1813 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1814 ioctls, and allow them to be defined for non-i386 platforms.
1816 The uuid.h header file is now protected against multiple inclusions.
1818 E2fsprogs is now being developed using BitKeeper. Changed the test
1819 scripts to deal with BK's stripping CR characgters from text files,
1820 and changed the top-level Makefile.in to avoid including BitKeeper
1821 files when generating the source tarball.
1824 E2fsprogs 1.21 (June 15, 2001)
1825 ==============================
1827 Added new configure flags which allow a subset e2fsprogs to be built;
1828 this is most useful for boot floopies, since the resulting shared
1829 libraries and programs are slimmed down by removing features that
1830 aren't necessary for a boot floppy. The new flags that were added
1831 are: --disable-swapfs, which removes support for byte swapping old
1832 legacy PPC/68k filesystems, --disable-debugfs, which removes support
1833 for debugfs from the libext2fs library, --disable-imager, which
1834 removes support for the e2image program, and --disable-resizer, which
1835 removes support for resize2fs.
1837 E2fsck now prints the number of mounts or days elapsed since the last
1838 check when e2fsck is forced to check an otherwise clean filesystem.
1840 Tune2fs now prints an informative message about how often a filesystem
1841 will be checked when adding a journal to the filesystem, to remind the
1842 user that he/she may want to adjust those parameters using tune2fs
1845 Worked around hurd brain-damage which causes e2fsck to sometimes
1846 believe a filesystem is the root filesystem based on device numbers
1847 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1850 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1851 erroneous error with the -F option was specified.
1853 Fixed a ext3 recovery bug in the revoke handling; synchronized with
1856 Fixed two bugs in e2fsck's handling of dup block handling, dealing
1857 with relatively uncommon edge cases: a directory with an indirect
1858 block which is claimed by another file, and when the last inode in the
1859 filesystem has blocks claimed by another file.
1861 E2fsck now checks to see if the i_size field of a fast symlink is too
1862 big, and offers to clear the symlink if so.
1864 E2fsck now checks to see if i_size_high of special files is non-zero,
1865 and offers to clear i_size_high.
1867 Fix e2fsck's handling of incompatible journal flags so that the user
1868 has chance to abort, and then has the option to clear out the journal
1869 entirely. (Addresses Debian bug #98527.)
1871 Fixed a bug in fsck which could cause it to core dump if a mix of
1872 standard and non-standard device names are used in /etc/fstab.
1873 (Debian bug #100559)
1875 Fixed a bug in debugfs which caused read errors when copying a file to
1878 The debugfs set_super_value command can now modify the s_lastcheck field.
1880 Fixed a bug in lsattr and chattr which was accidentally introduced in
1881 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
1882 directories correctly because the change modified the layout of struct
1883 dirent to be incompatible with the libe2p shared library.
1885 Cleaned up the mke2fs manual page and included a discussion about why
1886 it's good to periodically check the filesystem even when journaling is
1892 Fix general gcc -Wall complaints.
1894 The types needed by the ext2 header files are now provided by
1895 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1897 Integers are now preferred to longs when trying to find a 32-bit type
1898 in ext2_types.h. Also, if linux/types.h has already been defined,
1899 don't try to redefine the types.
1901 Fixed make depend script so that it automatically corrects the
1902 pathname cleanups performed by make -M, so I don't have to fix them up
1905 Fixed the d_loaddump test case to be more robust, and not depend on
1908 Removed debugfs's dependence on pread(), which was accidentally
1909 intrudced in e2fsprogs 1.20
1911 Fixed a performance bug in the libext2fs's icount routine; the size
1912 estimate of the icount array was incorrectly being calculated.
1914 Removed use of the badblocks compatibility functions in the e2fsprogs
1917 Added paranoia code which protects against strange cases where /etc
1918 isn't on the root filesystem, or if /etc/mtab doesn't exist.
1920 The header file ext2_types.h is now installed.
1922 Autoconf is used to determine when we are on big-endian machines,
1923 instead of doing run-time tests, to save a few bytes of code.
1925 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1926 functions are no longer inline functions, which saves space and
1927 doesn't really cost any real performance.
1929 The ext2fs library no longer depends on the e2p library. (What need
1930 there was of it --- namely, fsetflags, was coded in-line).
1932 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
1933 when the user is stupid and tries compiling the package using "make
1936 Miscellaneous code cleanups:
1937 * Added missing files from Makefile.in's SRCS file, so that
1938 their dependencies would be properly calculated.
1939 * Removed redundant code
1940 * Fixed comments in code
1941 * Removed no-longer unneeded argsused #pragma.
1944 E2fsprogs 1.20 (May 20, 2001)
1945 =============================
1947 Add support for replaying the ext3 journal purely in user mode,
1948 including handling the orphaned inode list. Used code contributed by
1949 Andreas Dilger, with bug fixes and the orphaned inode handling done
1952 The mke2fs and tune2fs programs can create or modify a filesystem to
1953 include an ext3 journal. Tune2fs also can be used to remove an ext3
1954 journal from a filesystem.
1956 E2fsck will now check for the existence of a linked list of orphan
1957 inodes in the superblock, and clear those inodes before starting the
1958 rest of the filesystem check (but after the journal playback).
1960 E2fsck now validates the file descriptor passed to the -C option,
1961 which saves against the completion bar getting written to an
1962 unexpected location, such as the disk being checked. (Debian
1963 bug/wishlist #55220)
1965 E2fsck will now bump the filesystem revision number from zero to one
1966 if any of the compatibility bits are set.
1968 Fixed a bug where a badly corrupted directory on a big endian system
1969 could cause e2fsck to die with a bus error. The
1970 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
1971 the ext2 library now does alignment sanity checks on the rec_len field
1972 of the directory entry before using it.
1974 The ext2 library has been enhanced to make tune2fs safe to run on
1975 mounted filesystems. (Users could usually get away with using tune2fs
1976 on mounted filesystems before, but with the advent of ext3 and
1977 journaling, it became important to make tune2fs was *really* safe for
1978 use even when the filesystem being modified is mounted.) E2label is
1979 now implemented by tune2fs using an argv[0] dispatch, so that e2label
1980 is also now safe for use on mounted filesystems.
1982 Added a new program, e2image, which creates a backup of critical ext2
1983 filesystem data structures. The generated image file can be examined
1984 using dumpe2fs and debugfs. In the future, e2fsck will be able to use
1985 the image file to help recover very badly damaged filesystems.
1987 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
1988 no longer cause e2fsck to bomb out. Also treat files > 2GB as being
1989 large file when deciding whether or not the filesystem has large files.
1991 Fixed lsattr and chattr so that they work correctly on large files.
1992 (Fixes Debian bug #72690.)
1994 Removed limitation in get_device_size() which imposed a one terrabyte
1995 filesystem limitation. (Most 2.2 kernels still have a signed int
1996 problem which cause 1 TB block device limitation. Fortunately, the
1997 kernel patches to fix this are much easier than fixing the 2TB
1998 limitation in the kernel. :-)
2000 A max_mount_count of zero is now treated as if no mount count were
2001 set. (Previously, no mount count was indicated by using -1, and a
2002 mount count of zero caused e2fsck to always be run.)
2004 Mke2fs supports two new filesystem types largefile and largefile4.
2006 Mke2fs now adds some randomness in s_max_mount_count so that multiple
2007 filesystems won't be all checked at the same time under normal
2010 Fixed bug in the progress bar printing code which could cause e2fsck
2011 to core dump on an illegal filesystem.
2013 Fixed bug in fsck which could allow more than one instance of e2fsck
2014 to be printing a progress bar. (Debian bug #65267)
2016 Fsck using a UUID or a LABEL specifier will work even if devfs is
2017 compiled into the kernel and not mounted. If the pathnames in
2018 /proc/partitions are incorrect, fsck will search /dev for the correct
2019 device (using the new ext2fs_find_block_device library function).
2020 Fsck now also checks the RAID devices first so that they are properly
2021 found when they are in use. Support has also been added to support
2022 additional IDE disks and the DAC 960 device names. (Debian bug #94159)
2024 Fixed a bug in fsck which caused it not deal properly with 16
2025 byte long filesystem labels.
2027 Fsck's -t option has been made a lot more flexible. The semantics for
2028 what happens if a comma-separated list to fsck has been regularized,
2029 and it is now possible to filter what filesystems will get checked
2030 based what is in the filesystem's fstab entry's option field. (Debian
2033 The dumpe2fs program can now print out the group description
2034 information in hex, and also prints the location of the superblock and
2035 block group descriptor for those block groups that have them.
2037 Mke2fs now clears the ext2 superblock before it starts creating a
2038 filesystem, so that the superblock magic number is only written if the
2039 filesystem creation process successfully completes.
2041 The debugfs program's stat command now pretty-prints the blocks used
2042 by an inode so that it's more compact and informative.
2044 The debugfs stats command now uses the same libe2p code (which is used
2045 by dumpe2fs) to print the superblock header information. This is more
2046 complete, and it avoids a bit of code duplication.
2048 Added a new debugfs command, set_super_value (ssv) which allows the
2049 user to set arbitrary superblock fields.
2051 Debugfs was extended to support inode numbers in hex (by prefixing
2052 them with 0x), and so that modify_inode can set the inode generation
2053 number. Also, there is now a new function command called logdump
2054 which will dump an ext3 journal.
2056 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
2059 Debugfs's dump command now stops immediately upon reporting a disk
2060 read error. (Fixed a bug in ext2fs_file_read library routine which
2061 caused debugfs not to stop.) (Debian bug #79163)
2063 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
2064 checked before /etc/mtab is used, since /proc/mounts is more likely to
2067 Added portability fixes for Solaris and Linux/ia64.
2069 Various manual pages were clarified and cleaned up. (Fixed debian
2070 bugs #63442, #67446, and #87216)
2076 The e2fsck message printer now supports %Iu and %Ig, which will print
2077 out the inode's user and group owners, respectively.
2079 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
2080 that no longer dependent on the system having the correct version of
2081 the kernel header files.
2083 Added a new function to libext2, ext2fs_find_block_device(), which
2084 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
2085 device given its device number.
2087 Added a new function to libext2, ext2fs_sync_device, which centralizes
2088 all of the places which might try to use the BLKFLSBUF or FDFLUSH
2089 ioctls (and usually failing to define them since the system header
2090 files don't usually do this for us, and we're trying to avoid usage of
2091 kernel include files now).
2093 Added new utility programs in tests/progs: random_exercise and
2094 hold_inode. They aren't built by default; they're useful for
2095 exercising ext3 filesystem code.
2097 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
2098 the filesystem close functions to only update the superblock, and to
2099 not touch the block group descriptors. Needed by tune2fs when
2100 modifying a mounted filesystem.
2102 Got rid of struct ext2fs_sb and replaced it with the standard struct
2103 ext2_super_block from include/linux/ext2_fs.h. Note: this may break
2104 source (but not binary) compatibility of some users of the ext2
2105 library. Those applications should just simply do a global search and
2106 replace of struct ext2fs_sb with struct ext2_super_block, and include
2107 the new header file <ext2fs/ext2_fs.h> which defines it.
2109 The ino_t type has been renamed ext2_ino_t to protect applications
2110 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
2111 inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
2112 unexpected ABI change.
2114 The Makefiles have been reworked so that "make check" can be run from
2115 the top-level Makefile.
2117 Fix general gcc -Wall complaints and removed dead code.
2119 Remove use of NOARGS, because we assume everyone does ANSI C these
2122 Added build-rpm script from sct.
2124 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
2127 New function ext2fs_flush_icache which must be called if the
2128 application program modifies the inode table blocks without going
2129 through ext2fs_write_inode() interface.
2131 New ext2fs_check_mount_point() function, which will return the mount
2132 point of a device if mounted.
2134 The io_channel abstraction now has an optional interface,
2135 io_channel_write_range, which allows specific byte ranges to be
2138 The unix_io IO channel now supports write-through caching, so that
2139 journal creation is more efficient.
2141 Added x86 assembly language routines to support byte swapping, to
2142 reduce executable size.
2144 Fixed bug in the utility program subst so that it's possible to
2145 replace a substitution variable with a zero-length string.
2147 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
2148 slipped into some of the problem number.
2150 E2fsprogs 1.19 (July 13, 2000)
2151 ==============================
2153 Release the resize2fs program since the timeout before it could
2154 be released under the GPL has finally expired.
2156 Add experimental support needed for the ext2 compression patches.
2157 This requires compiling e2fsprogs with the --enable-compression flag
2158 to the configure script.
2160 Added ext3 journalling support. E2fsck will run the journal (if
2161 necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
2162 installed as a symlink to e2fsck. Fsck has been taught about ext3,
2163 and treats it the same as ext2 in terms of the progress bar logic.
2164 Dumpe2fs will display the superblock journaling information if the
2165 filesystem has a journal. The ext2 library will now permit opening an
2166 ext3 filesystem with the recovery flag set. This is necessary for
2167 on-line dump's to work correctly, but there may be issues with this
2168 working well since ext3 is much less agressive about syncing blocks to
2169 the filesystem, since they're safe on the journal.
2171 Tune2fs and e2fsck have been changed to allow the mount_count check to
2172 be disabled by setting max_mount_count to -1. (This was already
2173 supported by the kernel.)
2175 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
2176 are used for ext3 as well.
2178 Added internationalization support for e2fsprogs; must be enabled
2179 by passing --enable-nls to configure.
2181 Always use the provided ext2fs header files to insulate ourselves from
2182 kernel version changes. Which include files are used by e2fsprogs
2183 have also been cleaned up to improve portability.
2185 Limit the number of times that e2fsck updates the progress bar so that
2186 people who are booting using a 9600 baud console don't get swampped by
2189 Improved the loop detection algorithm in e2sck's pass #3 so that it is
2190 much, much faster for large filesystems with a large number of
2193 The memory footprint for e2fsck is now slightly smaller than before.
2195 E2fsck now checks if special devices have a non-zero size, and offers
2196 to clear the size field if it finds such an inode.
2198 E2fsck now checks if special devices have the append-only flag set,
2199 and offers to clear the inode.
2201 E2fsck now properly handles some "should never fail" cases during a
2202 bitmap copy in pass5.
2204 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
2206 E2fsck now calculates the correct location of the backup superblock in
2207 the case of filesystem blocksizes > 1k.
2209 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
2210 which normally didn't cause problems under most filesystem parameters,
2211 but could cause a valid superblock to be rejected in extreme cases.
2212 Other checks for validating superblock values were made more
2215 Added non-destructive write testing to the badblocks program, courtesy
2216 of David Beattie. The badblocks also now has an option to input the
2217 current set of bad blocks, so that known bad blocks are skipped to
2218 speed up the badblocks test. There is also a persistent rescan
2219 feature which causes badblocks to run until it has completed some
2220 number of passes without discovering any new bad blocks.
2222 Badblocks now checks to see if the device is mounted and refuses to do
2223 the tests involving writing to the device if it is mounted. Also,
2224 badblocks now allows the number of blocks to be checked to be
2225 defaulted to the size of the partition.
2227 Fixed a bug in fsck which didn't allow non-root users to be able to
2228 check filesystems if there were any LABEL= or UUID= entries in
2231 The Hurd doesn't support the filetype filesystem feature. The mke2fs
2232 program now makes sure that for the Hurd, the filestype feature is
2233 turned off. E2fsck will check to see if the filetype feature is
2234 turned on for Hurd filesystems, and offer to turn off the feature.
2236 Mke2fs now has a safety check to make sure the number of blocks do not
2237 exceed 32 bits even on a 64 bit platform.
2239 Really fixed a bug in fsck to allow "fsck -As" to run interactive
2240 fsck's. (For those people who like to do interactive fsck's in the
2243 Debugfs has a few new features: the rdump command, which will do a
2244 recursive dump of a directory and all of its contents, and the lcd
2245 command which does a local chdir (much like the ftp command of the
2246 same name). In addition, the debugfs program and the open_filesystem
2247 command now takes three new options: -b and -s, which allows the
2248 blocksize and superblock location to be specified, and the -c option
2249 which is used in catastrophic situations where the block group
2250 descriptors are corrupt. If the -c option is specified, debugfs will
2251 skip trying to read in the block and inode bitmaps.
2253 Debufs's lsdel command was fixed to handle bad blocks in the inode
2256 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
2259 General improvements in error messages
2261 - Mke2fs prints a sane error message if the partition size is zero
2262 (usually because the partition table wasn't reread by the
2263 kernel due to the partition being busy), instead of "invalid
2264 argument passed to ext2 library while initializing superblock".
2266 - Fsck now prints more self-explanatory message if an invalid UUID=
2267 or LABEL= specification is passed to it.
2269 UUID library changed to use the LGPL.
2271 Fixed a bug in the UUID library where very rapid calls to the
2272 time-based UUID generator could cause duplicate UUID's to be returned.
2273 This was not a problem for e2fsprogs, but it could be a problem for
2274 other users of the library.
2276 Make the UUID library more robust in the face of missing or an
2277 improper /dev/urandom or /dev/random files.
2279 Added some random portability fixes for Solaris.
2281 Some minor man page updates.
2283 Fixed a memory leak in the ss library.
2289 We now try to use lseek64 and open64 from the LFS if possible.
2291 The 3rd parameter in e2p's print_flags is now a flags word, instead of
2294 The mark and unmark bitmap functions now return the previous state of
2295 the bit that was being changed, which is useful for some speed
2298 The following functions have been added to enhance the badblocks list
2299 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
2300 ext2fs_badblocks_equal.
2302 The ext2 header files now have the latest journalling fields to the
2305 The ext2fs_mkdir function in libext2fs now properly backs out of error
2306 conditions robustly.
2308 Cleaned up makefiles:
2309 - to cleanly compile with the -j flag.
2310 - so distclean removes all generated files.
2311 - so in case of an error while installing header files, the make aborts.
2313 Fix test_script so that it works correctly when compiling in the
2316 The random UUID generation routine has been made slightly better in
2317 the case where /dev/random doesn't exist. (Use of randomly-based UUID
2318 is still not recommended if /dev/random doesn't exist, however; it's
2319 better to use the time/ethernet MAC address UUID in this case.)
2321 Clean up the build process so it's more friendly in case of missing
2324 The ext2fs header file can now be #include'd into C++ programs.
2326 The e2p.h header file is now installed.
2328 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
2332 E2fsprogs 1.18 (November 10, 1999)
2333 ==================================
2335 Fix a core dumping bug in e2fsck if an imagic inode is present or
2336 (more rarely) if the filesystem is badly corrupted enough that e2fsck
2337 has to restart pass 1 processing. E2fsck now closes the filesystem
2338 before freeing a large number of its data structures, so in the case
2339 of future memory faults, at least the fixed filesystem will be fully
2342 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
2343 imagic inode, it will offer to clear the imagic flag.
2345 E2fsck will now offer to clear the immutable flag on special files
2346 (device/socket/fifos) when running it in non-preen mode.
2348 E2fsck will now set the filetype when creating /lost+found, and when
2349 connected orphaned inodes to /lost+found.
2351 Debugfs's ncheck and icheck commands now handles the case where there
2352 are bad blocks in the inode table without bombing out.
2354 The badblocks list processing code has been made more efficiently for
2355 appending a large number of (ordered) badblocks to the badblocks list.
2357 Some minor man page updates.
2359 Fsck now allows interactive e2fsck's when using fsck -As (not a common
2360 mode, but some people like to do this in boot scripts for silly reasons).
2365 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
2366 with the problem code convention.
2368 The badblocks list regression test program has been updated to work
2369 with previously made API name changes.
2371 The ext2fs_free() command now uses the new badblocks API to avoid
2372 using the compatibility layer.
2374 Added new regression test cases; the run_e2fsck test script now
2375 supports the ability for a test case to run a prepratory command
2376 before running e2fsck.
2378 E2fsprogs 1.17 (October 26, 1999)
2379 =================================
2381 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
2384 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
2385 thus potentially causing problems if a binary UUID contained a NULL
2388 E2fsck now uses stricter checks for directory entries in pass 2:
2389 zero-length filenames are not allowed; neither are 8 byte long
2392 The debugfs "dirty" command now clears the filesystem valid bit.
2393 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
2394 bit in the in-core superblock image. The new functionality is more
2395 what the user expects, and is more useful.)
2397 Added a debugging hook to test parallel fsck; if the environment
2398 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
2399 will be checked in parallel when they normally would not be.
2404 Fixed some #ifdef's for compilation under the Hurd OS.
2406 Fixed minor W2K compatibility problems.
2408 Fixed some miscellaneous GCC warnings.
2411 E2fsprogs 1.16 (October 22, 1999)
2412 =================================
2414 Fixed a race condition bug in fsck; when printing a progress bar, if
2415 checking multiple filesystems in parallel, it was possible for fsck to
2416 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
2417 handler, which would cause it to terminate with a signal 10.
2419 E2fsck now properly handles filesystems that have the
2420 INCOMPAT_FILETYPE feature turned on. It can be used to convert a
2421 filesystem into using or not using FILETYPE feature.
2423 E2fsck now properly handles filesystems that have the IMAGIC feature
2424 turned on (this is used on Linux AFS servers).
2426 The mke2fs program now creates filesystems that have the filetype and
2427 sparse_superblock features enabled by default, unless it is run on a
2428 pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
2429 so there is now a new flag -O which allows the user to specify with
2430 which features she would like to create the filesystem; "mke2fs -O
2431 none" will create a filesystsem compatible with 2.0 kernels.
2433 The tune2fs program now has a -O option which allows the user to set
2434 and reset "safe" filesystem features. Currently, the only ones which
2435 allows to be modified are the filetype and sparse_superblock features.
2436 Note setting or clearing either feature will require running e2fsck on
2437 the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
2438 requires that there is enough free space on the filesystem for the
2439 extra superblocks which will be created by e2fsck.)
2441 Debugfs can now set and print filesystem features in the superblock
2442 using the "features" command. Dumpe2fs will print out the complete
2443 set of features when listing the superblock.
2445 Dumpe2fs has new options -f (force) and -h (header-only).
2447 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
2448 message to come up. This could happen when decrementing or
2449 incrementing a link count could result in an overflow.
2451 Fixed a bug in e2fsck where the block count on the lost+found
2452 directory would not be properly incremented when the directory was
2453 expanded to the point where an indirect block needed to be allocated.
2455 E2fsck now makes some additional sanity checks on the superblock to
2456 avoid crashing or giving a memory allocation error if some of the
2457 values in the superblock are unresonable (but the superblock otherwise
2460 Fixed a bug in e2fsck where a very badly corrupted filesystem might
2461 require two passes to completely fix the filesystem. This happened if
2462 an inode claimed blocks that was part of the filesystem metadata
2463 (typically, when garbage was written into an inode table or indirect
2464 block, since this kind of filesystem corruption normally doesn't
2467 On the Alpha, glibc declares st_flags although it isn't actually used;
2468 the configure script was improved to detect this case so that
2469 e2fsprogs can avoid using the non-functional stat field.
2471 The manual pages were updated to use a more consistent formatting
2472 style consistent with standard Unix man pages. Mke2fs's man page
2473 added documentation for a few previously undocumented options.
2475 Fixed minor display bugs in tune2fs and mke2fs.
2480 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
2482 Added features to parse and print feature strings into the e2p library.
2483 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
2485 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
2486 whose directory entries contain proper filetype information if the
2487 filesystem supports it.
2489 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
2490 the directory entry filetype information. This is used to set the
2491 directory entry filetype information if the filesystem supports it.
2493 Fixed a bug in ext2fs_expand_dir() where the block count in a
2494 directory's inode would not be properly incremented when the directory
2495 was expanded to the point where an indirect block needed to be
2499 E2fsprogs 1.15 (July 18, 1999)
2500 ==============================
2502 Add configuration checks so that e2fsprogs will compile cleanly on
2503 Linux 2.3 kernels that have renamed i_version to i_generation.
2505 E2fsck now prints a progress/completion bar (and not just a simple
2506 spinner) if the -C0 option is requested or if it receives a SIGUSR1
2507 signal. Fsck will automatically manage the (potentially muliple)
2508 e2fsck processes to print completion bars if it is given a -C option,
2509 with the right thing happening if multiple filesystems are being
2510 checked in parallel.
2512 Mke2fs now has better automatic hueristics to determine the filesystem
2513 parameters to be used for a particular filesystem. Added a new option
2514 -T which allows the user to specify how the filesystem is to be used,
2515 which helps mke2fs do a better job selecting the filesystem parameters.
2517 Mke2fs now creates revision 1 filesystems by default, and with the
2518 sparse superblock feature enabled. The sparse superblock feature is
2519 not understood by Linux 2.0 kernels, so they will only allow read-only
2520 mounts of filesystems with this sparse superblocks.
2522 Fix bug where if /dev/null couldn't be opened (should never happen),
2523 e2fsck would hang in a tight loop.
2525 Make e2fsck handle the case where /lost+found isn't a directory.
2527 E2fsck now uses mallinfo if it exists to get accurate statistics about
2530 Fix bug in e2fsck where it wouldn't check to see if a disconnected
2531 inode had any problems before connecting it to /lost+found.
2533 Add check to e2fsck so it makes sure that total number of inodes in
2534 the filesystem is a sane number.
2536 Fix fencepost error when clearing an the end of the block bitmap which
2537 caused the last block in the bitmap not to get cleared.
2539 Cleaned up a number of messages in e2fsck:
2540 * The message "Group's #'s copy of the group descriptor..."
2541 was fixed so that the correct number would be displayed.
2542 * Added missing space in the "disk write-protected" error messsage
2543 * Cleaned up the error message printed when a non-interactive
2544 e2fsck needs to abort a check because the filesystem
2545 appears to be mounted.
2547 Added a new command-line utility, uuidgen, which will create and print
2550 Make debugfs's icheck command more robust by checking to make sure an
2551 inode has valid blocks before interarting over the inode's blocks.
2553 UUID generation now uses a random-based scheme whenever possible to
2554 prevent potential privacy problems.
2556 Man pages for all of the UUID functions in the lirbary were added.
2558 Fixed bug in fsck so it won't coredump if a filesystem not in
2559 /etc/fstab is given to it.
2561 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2562 that most of the other mount utilities understands.
2564 Mke2fs will make a filesystem even if it appears mounted if the force
2567 Dumpe2fs has new command-line options which allow a filesystem expert
2568 to specify the superblock and blocksize when opening a filesystem.
2569 This is mainly useful when examining the remains of a toasted
2572 The badblocks program has been updated to display correctly on disks
2573 with large block numbers.
2575 The badblocks program no longer gives spurious errors when errors
2576 occur on non-block boundaries, which is common if the blocksize is
2579 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2580 MKE2FS_SYNC environment variable is set. This is to work around a VM
2581 bug in the 2.0 kernel. I've heard a report that a RAID user was able
2582 to trigger it even using a 2.2 kernel, but hopefully it will not be
2583 needed for most Linux 2.2 users.
2585 Fixed miscellaneous documentation and man pages.
2590 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2591 in e2fsck's pass1.c really should have been static.
2593 The return value of the uuid_compare() function was changed to make it
2594 match with the convetions used by strcmp, memcmp, and Paul Leach's
2595 UUID sample document.
2597 The "make depend" process has now been made more automated; it now
2598 automatically word-wraps the dependencies, and only replaces source
2599 Makefile.in if there has been a change in the dependencies. Also, a
2600 top-level "make depend" now recurses through all the subdirectories
2603 The Makefile in .../util has been changed so that subst is built using
2604 the native C compiler during a cross-compilation, since the subst
2605 program is only used during the build process. Also add an explicit
2606 rule to build util/subst by cd'ing to the correct directory and
2609 The man directories are defined in terms mandir, so that the configure
2610 script can override the location of the manual pages.
2612 The config files have been updated to recognize new machine types for
2613 both the i386 and alpha families.
2615 Fsck has been modified so that it will accurately create an
2616 fsck_instance even when the noexecute flag is set. This allows for
2617 accurate debugging of the fsck pass structure. Also, when the verbose
2618 flag is given twice, fsck will print debugging information about when
2619 fsck is waiting for jobs to finish.
2622 E2fsprogs 1.14 (January 9, 1999)
2623 ================================
2625 Fix the fstab parsing code so that it can handle blank lines and
2626 comment characters. Also, missing pass numbers need to be treated as
2629 Fixed a bug in e2fsck where under some circumstances (when e2fsck
2630 needs to restart processing after fixing an egregious inconsistency)
2631 it would try to access already freed memory.
2633 E2fsck now prints non-printable characters in directory entries and
2634 pathnames using '^' and 'M-' notation.
2636 Fixed chattr so that it will ignore symbolic links when doing
2637 recursive descent traversals. For both chattr and lsattr, no longer
2638 print the version string unless the -V option is given.
2640 Allow the system administrator to directly specify the number of
2641 inodes desired in the filesystem, for some special cases where this is
2644 Fix portability problems so that e2fsprogs can be compiled under Linux
2645 1.2 systems and Solaris systems.
2647 Update the config.guess file with a more recent version that will
2648 identify newer Linux platforms.
2653 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2654 an inode number of zero is passed to them.
2656 E2fsprogs 1.13 (December 15, 1998)
2657 ==================================
2659 Fixed a bug in debugfs where an error messages weren't getting printed
2660 when the ext2 library routines to read inodes returned errors in the
2661 stat, cmri and rm commands.
2663 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2664 provided, it won't create an inode table smaller than the minimum
2665 number of inodes required for a proper ext2 filesystem.
2667 Fsck now parses the /etc/fstab file directly (instead of using
2668 getmntent()), so that it can distinguish between a missing pass number
2669 field and pass number field of zero. This caused problems for
2670 diskless workstations where all of the filesystems in /etc/fstab have
2671 an explicit pass number of zero, and fsck could not distinguish this
2672 from a /etc/fstab file with missing pass numbers.
2674 E2fsck will create a /lost+found directory if there isn't one in the
2675 filesystem, since it's safer to create the lost+found directory before
2678 Fixed e2fsck so that it would detect bogus immutable inodes which
2679 happen to be sockets and FIFO files, and offer to clear them.
2681 If a filesystem has multiple reasons why it needs to be checked, and
2682 one of the reasons is that it is uncleanly mounted, e2fsck will print
2683 that as the reason why the filesystem is being checked.
2685 Cleaned up the output routines of mke2fs so that it doesn't overflow
2686 an 80 column display when formating really big filesystems.
2688 Added a sanity check to e2fsck to make sure that file descriptors 0,
2689 1, 2 are open before opening the hard disk. This avoids a problem
2690 where a broken program might exec e2fsck with those file descriptors
2691 closed, which would cause disastrous results if the kernel returns a
2692 file descriptor for the block device which is also used by FILE *
2695 Fixed up the e2fsck progress reporting functions so that the values
2696 reliably reach 100% at the completion of all of the e2fsck passes.
2698 Fixed minor documentation bugs in man pages and usage messages.
2703 Fixed a number of lint warnings in the ext2fs library and potential
2704 portability problems from other OS's header files that might define
2705 CPP macros for names like "max" and "min".
2707 ext2fs_badblocks_list_add() has been made more efficient when it needs
2708 to grow the bad blocks list.
2710 Fixed a bug in e2fsck which caused it to dereference a freed pointer
2711 just before exiting.
2713 Fixed the substition process for generating the mk_cmds and compile_et
2714 scripts so that they will work outside of the build tree.
2716 Add sanity check to e2fsck so that if an internal routine
2717 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2718 and causing a core dump. This should never happen, but...
2720 E2fsprogs 1.12 (July 9, 1998)
2721 ==================================
2723 E2fsprogs now works with glibc (at least with the version shipped wtih
2724 RedHat 5.0). The ext2fs_llseek() function should now work even with
2725 i386 ELF shared libraries and if llseek() is not present. We also
2726 explicitly do a configure test to see if (a) llseek is in libc, and
2727 (b) if llseek is declared in the system header files. (See standard
2728 complaints about libc developers don't understand the concept of
2729 compatibility with previous versions of libc.)
2731 The ext2fs library now writes out the block group number in each of
2732 the superblock copies. This makes it easier to automatically
2733 determine the starting block group of the filesystem when the block
2734 group information is trashed.
2736 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
2737 which means that e2fsprogs will ignore the high 8 bits of the
2738 directory entry's name_len field, so that it can be used for other
2741 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2742 E2fsprogs will now support filesystems with 64-bit sized files.
2744 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2746 Added new program "e2label", contributed by Andries Brouwer. E2label
2747 provides an easy-to-use interface to modify the filesystem label.
2749 Fixed bug so that lsattr -v works instead of producing a core dump.
2751 Fixed a minor bug in mke2fs so that all groups with bad superblock
2752 backup blocks are printed (not just the first one).
2754 Mke2fs will check the size of the device, and if the user specifies a
2755 filesystem size larger than the apparent size of the device it will
2756 print a warning message and ask if the user wants to proceed.
2758 E2fsck has a new option -C, which sends completion information to the
2759 specified file descriptor. For the most part, this is intended for
2760 programs to use, although -C 0 will print a spinning character to the
2761 stdout device, which may be useful for users who want to see something
2762 happening while e2fsck goes about its business.
2764 Fixed a bug in e2fsck which could cause a core dump when it needs to
2765 expand the /lost+found directory, and sometimes the bitmaps haven't
2766 been merged in. Also fixed a related bug where ext2fs_write_dir_block
2767 was used to write out a non-directory block. (Which would be bad on a
2768 non-Intel platform with byte swapping going on.)
2770 Fixed bug in e2fsck where it would print a "programming error" message
2771 instead of correctly identifying where a bad block was in used when
2772 the bad block was in a non-primary superblock or block group
2773 descriptor. Also fixed a related bug when sparse superblocks are in
2774 use and there is a bad block where a superblock or block group
2775 descriptor would have been in a group that doesn't include a
2778 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2779 the block group descriptor table is corrupt, it was possible to try to
2780 allocate a huge array, fail, and then abort e2fsck.
2781 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2782 and subsitutes reasonable values if the descriptors are obviously bogus.
2784 If e2fsck finds a device file which has the immutable flag set and the
2785 i_blocks beyond the normal device number are non-zero, e2fsck will
2786 offer to remove it, since it's probably caused by garbage in the inode
2789 When opening a filesystem, e2fsck specially checks for the EROFS error
2790 code, and prints a specific error message to the user which is more
2793 If the filesystem revision is too high, change the e2fsck to print
2794 that this is either because e2fsck is out of date, or because the
2795 superblock is corrupt.
2797 E2fsck now checks for directories that have duplicate '.' and '..'
2798 entries, and fixes this corruption.
2800 E2fsck no longer forces a sync of the filesystem (with attendant sleep
2801 calls) at all times. The ext2fs_flush() function now performs a sync
2802 only if it needed to write data blocks to disk.
2804 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2805 certain errors would not be properly reported.
2807 Updated and expanded a few points in the man pages which users
2808 complained wheren't explicit enough.
2810 Added special case byte-swapping code if compiling on the PowerPC, to
2811 accomodate the strange big-endian variant of the ext2 filesystem that
2812 was previously used on the PowerPC port.
2818 Removed C++ keywords from the ext2fs libraries so that it could be
2821 E2fsck's internal organization has now been massively reorganized so
2822 that pass*.c don't have any printf statements. Instead, all problems
2823 are reported through the fix_problem() abstraction interface. E2fsck
2824 has also been revamped so that it can be called as a library from a
2827 Added new fileio primitives in libext2fs for reading and writing
2828 files on an unmounted ext2 filesystem. This interface is now used by
2831 Added a new libext2fs function for mapping logical block numbers of
2832 a file to a physical block number.
2834 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2835 a block, zeros it, and updates the filesystem accounting records
2838 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2839 sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2841 The libext2fs functions now use a set of memory allocation wrapper
2842 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2843 instead of malloc, free, and resize. This makes it easier for us to
2844 be ported to strange environments where malloc, et. al. aren't
2845 necessarily available.
2847 Change the libext2fs fucntion to return ext2-specific error codes
2848 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2849 and depending on the existence of system error codes (such as EEXIST
2852 Renamed io.h to ext2_io.h to avoid collision with other OS's header
2855 Add protection against ext2_io.h and ext2fs.h being included multiple
2858 The types used for memory lengths, etc. have been made more portable.
2859 In generla, the code has been made 16-bit safe. Added Mark
2860 Habersack's contributed DOS disk i/o routines.
2862 Miscellaneous portability fixes, including not depending on char's
2865 The io_channel structure has a new element, app_data, which is
2866 initialized by the ext2fs routines to contain a copy of the filesystem
2869 ext2fs_check_directory()'s callback function may now return the error
2870 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2871 really do the checking, despite the presence of the callback function.
2874 E2fsprosg 1.11 (June 17, 1997)
2875 ==============================
2877 Fixed e2fsck to detect (previously ignored) conflicts between the
2878 superblock or block group descriptors and block bitmaps, inode
2879 bitmaps, and inode tables.
2881 Fixed bug in e2fsck so that when the message printed out when a block
2882 or inode bitmap conflicts with other data, it has the correct group
2885 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2886 to badblocks. This meant that not all of the filesystem was being
2887 tested for bad blocks!
2889 Fixed an array boundary overrun case which cropped up in
2890 ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2893 Adjusted the number of columns printed by mke2fs when displaying the
2894 superblock backups to avoid running over 80 columns when making a
2895 really big filesystem.
2897 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2898 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2899 fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2904 Fixed install rule in lib/ss so that ss_err.h is actually getting
2907 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2908 bassed back to the caller.
2910 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2911 setting the current inode number (which meant this function wasn't
2914 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2915 blocks in the bitmap when increasing the size of the bitmap.
2917 Changed the initial number of blocks allocated by ext2fs_init_dblist()
2918 to be more realistic.
2920 Added a new function ext2fs_allocate_group_table, which sets up the
2921 group descriptor information (and allocates inode and block bitmaps,
2922 and inode tables for a particular group). The function was created by
2923 factoring out code form ext2fs_allocate_tables().
2925 Added a new function ext2fs_move_blocks which takes a bitmap of the
2926 blocks to be moved, and moves them to another location on the
2929 Make the unix_io channel's io_channel_flush implementation calls sync()
2930 to to flush the kernel buffers to disk.
2932 Added a new function ext2fs_dblist_count returns the number of
2933 directory blocks in dblist.
2936 E2fsprogs 1.10 (April 24, 1997)
2937 ===============================
2939 Mke2fs once again defaults to creating revision #0 filesystems, since
2940 people were complaining about breaking compatibility with 1.2 kernels.
2941 Warning messages were added to the mke2fs and tune2fs man pages that
2942 the sparse superblock option isn't supported by most kernels yet (1.2
2943 and 2.0 both don't support parse superblocks.)
2945 Added new flag to mke2fs, -R <raid options>, which allows the user to
2946 tell mke2fs about the RAID configuration of the filesystem. Currently
2947 the only supported raid option is "stride" which specifies the width
2950 Fixed bug in e2fsck where pass1b would bomb out if there were any
2951 blocks marked bad in the inode table.
2953 Fixed rare bug in mke2fs where if the user had a very unlucky number
2954 of blocks in a filesystem (probability less than .002) the resulting
2955 filesystem would be corrupt in the last block group.
2957 Fixed bug where if e2fsck tried to allocate a block to fix a
2958 filesystem corruption problem and the filesystem had no free blocks,
2959 ext2fs_new_block() would loop forever.
2961 The configure script now checks explicitly to see if "-static" works,
2962 since that can't be assumed to be true --- RedHat doesn't install
2963 libc-static by default.
2965 Fixed bug in libext2's block iterator functions where under some
2966 cirmcustances, file with holes would cause the bcount parameter to the
2967 callback function to be incorrect. This bug didn't affect any of
2968 e2fsprogs programs, but it was discovered by Paul Mackerras, the
2969 author of the PPC boot loader.
2971 Removed use of static variables to store the inode cache in libext2fs.
2972 This caused problems if more than one filesystem was accessed via
2973 libext2fs (static variables in libraries are generally a bad idea).
2974 Again, this didn't affect e2fsprogs programs, but it was discovered by
2977 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
2978 will compile cleanly with 1.2.13 kernels (even with a.out shared
2984 Added new functions to duplicate an ext2 filesystem handle, and its
2985 associated substructure. New functions: ext2fs_dup_handle(),
2986 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
2987 Other structures, such as the io_channel and the inode_cache, now have
2988 a ref count so that they only get freed when they are no longer used
2989 by any filesystem handle. (These functions were added as part of the
2990 development effort for an ext2 resizer).
2992 E2fsprogs 1.09 (April 14, 1997)
2993 ===============================
2995 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
2996 accidentally introduced in the 1.08 release. The overhead calculation
2997 was accidentally removed, which caused ext2fs_initialize() to not
2998 notice when the filesystem size needed to be adjusted down because
2999 there wasn't enough space in the last block group.
3001 Fixed bug in version parsing library routine; it was always parsing
3002 the library version string, instead of using the passed-in string.
3004 Clarified chattr man page.
3006 E2fsprogs 1.08 (April 10, 1997)
3007 ===============================
3009 E2fsck 1.07 was very slow when checking very large filesystems with a
3010 lot of files that had hard links (i.e., news spools). This was fixed
3011 by seriously revamping the icount abstraction. Added a formal test
3012 suite for the icount abstraction.
3014 Debugfs now has a "-l" option to the "ls" command, which lists the
3015 inode number, permissions, owner, group, size, and name of the files
3018 Fix a bug in e2fsck where when a directory had its blocks moved to
3019 another location during the pass 1b processing, the directory block
3020 list wasn't updated, so pass 2 wouldn't check (and correct) the
3021 correct directory block.
3023 E2fsck will now treat inodes which contain blocks which are claimed by
3024 the filesystem metadata by treating them as multiply claimed blocks.
3025 This way, the data in those blocks can be copied to a new block during
3026 the pass 1b--1d processing.
3028 E2fsck will attempt to determine the correct superblock number and
3029 display it in the diagnostic and warning messages if possible.
3031 Add support for a new (incompatible) feature, "sparse_super". This
3032 feature reduces the number of blocks which contain copies of backup
3033 superblocks and block group descriptors. (It is only an incompatible
3034 feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
3035 support a new -s option; e2fsck will recognize filesystems built with
3036 this feature turned on.
3038 E2fsck now checks the library to make sure is the correct version,
3039 using new library functions. (This helps to diagnose incorrectly
3040 installed e2fsprogs distributions.)
3042 Dumpe2fs now prints more information; its now prints the the
3043 filesystem revision number, the filesystem sparse_super feature (if
3044 present), the block ranges for each block group, and the offset from
3045 the beginning of the block group.
3047 Mke2fs now distributes the inode and block bitmap blok so that the
3048 won't be concentrated in one or two disks in RAID/striping setups.
3049 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
3050 choose the largest blocks per group that be chosen. (For 2k blocks,
3051 you can have up to 16384 blocks/group; for 4k blocks, you can have up
3052 to 32768 blocks/group.) Previously mke2fs would not allow
3053 specification of more than 8192 blocks per group, even if you were
3054 using a 2k or 4k block group.
3059 Added a new function ext2fs_create_icount2() which takes a "hint"
3060 argument. This hint argument presets the icount array with the list
3061 of inodes which actually need to be in the icount array. This really
3062 helps to speed up e2fsck.
3064 Added a new function ext2fs_icount_validate() which checks the rep
3065 invariant for the icount structure. This is used mostly for testing.
3067 The error mesasage given when a bad inode number is passed to
3068 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
3069 EXT2FS_UNMARK_ERROR).
3071 Added a new function ext2fs_set_dir_block which sets the block of a
3072 dblist entry, given the directory inode and blockcnt.
3074 Added a new function ext2fs_get_library_version() which returns the
3075 current library version, and ext2fs_parse_version_string() which
3076 returns a version number based on a e2fsprogs version string.
3078 The icount functions will return EINVAL if the passed in inode number
3081 E2fsprogs 1.07 (March 9, 1997)
3082 ==============================
3084 E2fsck is now uses much less memory when checking really large
3085 filesystems (or rather, filesystems with a large number of inodes).
3086 Previously a filesystem with 1 million inodes required 4 megabytes of
3087 memory to store inode count statistics; that storage requirement has
3088 now been reduced to roughly half a megabyte.
3090 E2fsck can now properly deal with bad blocks appearing inside the
3091 inode table. Instead of trying to relocate the inode table (which
3092 often failed because there wasn't enough space), the inodes in the bad
3093 block are marked as in use.
3095 E2fsck will automatically try to use the backup superblocks if the
3096 primary superblocks have a bad magic number or have missing meta-data
3097 blocks (or meta-data blocks which are out of range).
3099 E2fsck's pass 3 has been made more efficient; most noticeable on
3100 filesystems with a very large number of directories.
3102 Completely revamped e2fsck's system of printing problem reports. It
3103 is now table driven, to make them more easily customizeable and
3104 extendable. Error messages which can be printed out during preen mode
3105 are now one line long.
3107 Fixed e2fsck's filesystem swapping code so that it won't try to swap
3108 fast symbolic links or deleted files.
3110 Fixed e2fsck core dumping when fixing a filesystem which has no
3111 directories (not even a root directory).
3113 Added a check to e2fsck to make sure that the length of every
3114 directory entry is a multiple of 4 (since the kernel complains if it
3117 Added a check to e2fsck to make sure that a directory entry isn't a
3118 link to the root directory, since that isn't allowed.
3120 Added a check to e2fsk to now make sure the '.' and '..' directory
3121 entries are null terminated, since the 2.0 kernel requires it.
3123 Added check to write_bitmaps() to make sure the superblock doesn't get
3124 trashed if the inode or block bitmap is marked as being block zero.
3126 Added checking of the new feature set fields in the superblock, to
3127 avoid dealing with new filesystem features that this package wasn't
3130 Fixed a fencepost error in ext2fs_new_block() which would occasionally
3131 try to allocate a block beyond the end of a filesystem.
3133 When the UUID library picks a random IEEE 802 address (because it
3134 can't find one from a network card), it sets the multicast bit, to
3135 avoid conflicting with a legitimate IEEE 802 address.
3137 Mke2fs now sets the root directory's owner to be the real uid of the
3138 user running mke2fs. If the real uid is non-zero, it also sets
3139 the group ownership of the root directory to be the real group-id of
3140 the user running mke2fs.
3142 Mke2fs now has more intelligent error checking when it is given a
3143 non-existent device.
3145 When badblocks is given the -vv option, it now updates the block that
3146 it is currently testing on every block.
3148 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
3149 currently correctly if PATH wasn't already set.
3151 Shared libraries now built with dependencies. This allows the shared
3152 library files to be used with dlopen(); it also makes the transition
3153 to libc 6 easier, since ld.so can tell which libc a particular shared
3154 library expects to use.
3159 Added new abstraction (defined in dblist.c) for maintaining a list of
3160 blocks which belongs to directories. This is used in e2fsck and other
3161 programs which need to iterate over all directories.
3163 Added new functions which test to see if a contiguous range of blocks
3164 (or inodes) are available. (ext2fs_*_bitmap_range).
3166 Added new function (ext2_inode_has_valid_blocks) which returns true if
3167 an inode has valid blocks. (moved from e2fsck code).
3169 Added new function (ext2fs_allocate_tables) which allocates the
3170 meta-data blocks as part of initializing a filesystem. (moved from
3173 Added a new I/O manager for testing purposes. It will either allow a
3174 program to intercept I/O requests, or print debugging messages to
3175 trace the activity of a program using the I/O manager.
3177 The badblocks_list functions now store the bad blocks in a sorted
3178 order, and use a binary search to speed up badblocks_list_test.
3180 The inode scan function ext2fs_get_next_inode() may now return a soft
3181 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
3182 those cases where part of an inode table is missing or there is a bad
3183 block in the inode table.
3185 Added a new function (ext2fs_block_iterate2) which adds new arguments to
3186 the callback function to return a pointer (block and offset) to the
3187 reference of the block.
3189 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
3190 application to jump to a particular block group while doing an inode
3193 The badblocks list functions were renamed from badblocks_* to
3194 ext2fs_badblocks_*. Backwards compatibility functions are available
3195 for now, but programs should be modified to use the new interface.
3197 Some of the library functions were reorganized into separate files to
3198 reduce the size of some programs which statically link against the
3201 Put in some miscellaneous fixes for the Alpha platform.
3204 E2fsprogs 1.06 (October 7, 1996)
3205 ================================
3207 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
3208 smash the backup copies in ext2fs_close(). (The problem was that when
3209 e2fsck -p discovered the problem, while it was closing the filesystem
3210 and exiting, it was also blowing away the backup superblocks on the
3211 disk, which was less than friendly.) We now make it the case that we
3212 only write out the backup superblock and the back block descriptors if
3213 the filesystem is completely free from problems.
3215 Fixed a bug in block_interate in the lib/ext2fs library which caused
3216 e2fsck to fail on GNU Hurd-created filesystems.
3218 Add support for Linux/FT's bootloader, which actually uses
3219 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
3222 Add support for the "A" (no atime update) attribute. (Note: this
3223 attribute is not yet in production kernels.)
3225 The test suite is not automatically run when doing a "make all" from
3226 the top level directory. Users should manually run "make check" if
3227 they wish to run the test suite.
3229 Upon a preenhalt(), make the printed message more explicit that
3230 running e2fsck "MANAULLY" means without the -p or -a options.
3232 In e2fsck, if a disconnected inode is zero-length, offer to clear it
3233 instead of offering to connect it to lost+found.
3235 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
3236 e2fsck to be run over it, change e2fsck to explicitly display this
3239 For dumpe2fs and e2fsck, cause the -V option to print out which
3240 version of the ext2fs library is actually getting used. (This will
3241 help detect mismatches of using a 1.06 utility with a 1.05 library,
3247 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
3248 the naming convention.
3250 In ext2fs_initialize(), make sure the description for the inode bitmap
3251 is correctly initialize.
3253 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
3255 E2fsprogs 1.05 (September 7, 1996)
3256 ==================================
3258 Add support for new fields in the ext2 superblock --- volume name,
3259 volume UUID, and last mounted field. Dumpe2fs displays these fields,
3260 tune2fs and mke2fs allows you to set them. E2fsck will automatically
3261 generate a UUID for those volumes that don't have them.
3263 Put in support for e2fsck to recognize HURD specific ext2 features ---
3264 most notably, the translator block. The e2fsprogs tools will now use
3265 the creator_os field in the superblock to correctly handle different
3266 OS-specific variants of the ext2 filesystem.
3268 E2fsck now fixes inodes which have a the deletion time set, but which
3269 have a non-zero i_link_count field by offering to clear the deletion
3270 time. Previously e2fsck assumed that the inode was deleted (per 0.3c
3271 ext2 kernel behavior) and offered to unlink the file.
3273 If e2fsck sets the clean bit, but nothing else, set the exit code
3274 FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
3275 set the filesystem valid bit when it was previously cleared. :-) This
3276 was needed to make the HURD fsck driver happy.
3278 If the user refuses to attach an unattached inode, e2fsck will no
3279 longer set the inode's link count. Otherwise, the inode would end up
3280 getting marked as unused, which might cause loss of data later.
3282 Make the message issued by e2fsck when the superblock is corrupt less
3283 confusing for users. It now mentions that another reason for the
3284 "corrupt superblock" message might be that the partition might not be
3285 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
3287 Make the libext2 library more robuest so that e2fsck won't coredump on
3288 an illegal superblock where the blocksize is zero. (f_crashdisk is
3291 By default, create filesystems where the default checkinterval is 6
3292 months (180 days). Linux servers can be robust enough that 20 reboots
3293 can be a long, long time.
3295 Added configure flag --enable-old-bitops, which forces the bitops to
3296 use the old (native) bitmask operations. By default on the sparc
3297 platform, the standard ext2 bit ordering is now used.
3299 Added a new feature to e2fsck to byte-swap filesystems; this can be
3300 used to convert old m68k filesystems to use the standard byte-order
3301 storage for the superblock, inodes, and directory blocks. This
3302 function is invoked by using the '-s' option to e2fsck.
3304 Debugfs's "dump" command has been enhanced so that it writes out the
3305 exact size of the file so that the nulls at the end of the file are
3306 eliminated. The command also accept a new "-p" option which will
3307 attempt preserve to preserve the ownernship, permissions, and
3308 file modification/access times.
3310 Debugfs has two new options, -f and -R. The -R option allows the user
3311 to execute a single debugfs command from the command line. The -f
3312 option allows the user to specify a "command file" containing debugfs
3313 commands which will get executed.
3315 Dumpe2fs now pretty prints the check interval, instead of just
3316 printing the check interval as a number of seconds.
3318 Fix bugs in debugfs: the params command when no filesystem is opened
3319 no longer causes a core dump. It is now possible to unlink a file
3320 when a pathame containing a '/' is specified.
3322 Tune2fs has a new -C option which sets the number of times the
3323 filesystem has been mounted.
3325 Fix the chattr '-v' option so that it actually works. Chattr was
3326 being buggy about the -v option parsing.
3331 The directory lib/uuid contains a set of library routines to generate
3332 DCE compatible UUIDs.
3334 Extended ext2fs_namei() to handle symbolic links. Added new function
3335 ext2fs_nami_follow() which will follow last symbolic link in the case
3336 where the pathname points to a sym link.
3338 The ext2fs_block_iterate function will now return the HURD translator
3339 block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
3340 iterator to return data blocks only. The ext2fs.h file now defines
3341 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
3342 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
3343 count field of the iterator callback function.
3345 The test script driver now takes an optional second argument, which is
3346 the test case to be run. This allows you to run a test case without
3347 needing to run the entire test suite.
3349 On Linux ELF systems, install the .so files in the correct places
3350 (/usr/lib). The .so files must be stored in the same directory as the
3353 Fixed miscellaneous HURD compilation issues with header file being
3354 included in the right order.
3356 Fixed debugfs so that it resets optind to zero, not one, since setting
3357 optind to zero is more correct.
3360 E2fsprogs 1.04 (May 16, 1996)
3361 =============================
3363 First "official" (1.03 was a limited release only) to support building
3364 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
3367 This package includes a RPM specs file, that it can be built using the
3368 RedHat Package Manager.
3370 E2fsck now prints a hint that if there are lots of incorrectly located
3371 inode bitmaps, block bitmaps, and inode table blocks, the user might
3372 want to try using e2fsck -b 8193 first, to see if that fares any
3375 For ext2 filesystem written with the hurd, debugfs will now print out
3376 the translator field when printing an inode structure.
3378 Lots of miscellaneous linking/installation cleanups:
3380 Libraries are now linked using a relative pathname, instead of
3381 relying on -L working correct. It doesn't, in many cases, including
3382 current versions of GNU ld. This guarantees that the build tree is
3383 linking with the right libraries, instead of the ones installed in
3386 Header files, man pages, and the et/ss shell scripts are now
3387 generated using a custom substitution script, instead of relying on
3388 the configure script. This prevents needless recompilation of
3389 files; in addition, the custom substitution script is much faster.
3391 e2fsck may now be linked dynamically, by using the
3392 --enable-dynamic-e2fsck flag to configure. This is not recommended,
3393 since it increases e2fsck's dependence on other files, but some
3394 people need to save disk space, and other critical programs on their
3395 systems were being linked dynamically anyway.
3397 Programs such as fsck which didn't need to be linked against
3398 libext2fs (or mke2fs which didn't need to be linked against libe2p)
3399 only link against libraries they actually need. Otherwise, those
3400 programs would require the presense of libraries that otherwise
3401 could be removed from a rescuse diskette.
3403 The ss include files are now installed correctly so they can
3404 actually be used by another package.
3406 If the profiling libraries are built, they are now installed on a
3407 "make install-libs".
3410 E2fsprogs 1.03 (March 27, 1996)
3411 ===============================
3413 Change the m68k bit numbering for bitmasks to match the bit numbering
3414 used by all other ext2 implementations. (This change was requested by
3415 the m68k kernel development team.)
3417 Support (in-development) filesystem format revision which supports
3418 (among other things) dynamically sized inodes.
3420 Fixed a bug in the ext2 library so that an intelligent error is
3421 returned if mke2fs is run with a ridiculously small number of blocks
3424 Fixed a bug in the ext2 library which required that the device be
3425 openable in read/write mode in order to determine its size. This
3426 caused e2fsck -n to require read/write access when it was not
3427 previously necessary.
3429 Fixed a bug in e2fsck which casued it to occasionally fail the test
3430 suite depending on which version of the floating point library it was
3433 Fixed a bug in e2fsck so that it now halts with a fatal error when
3434 certain superblock consistency checks fail. Previously it continued
3435 running e2fsck, with some potential confusing/damaging consequences.
3437 Added new flag to fsck which allows the root to be checked in parallel
3438 with other filesytems. This is not the safest thing in the world to
3439 do, but some system administrators really wanted it.
3441 Fixed -Wall flames in lib/ss.
3444 E2fsprogs 1.02 (January 16, 1996)
3445 =================================
3447 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
3449 Change e2fsck to print statistics of how many non-contiguous files are
3450 on the system. Note that a file which is larger than 8k blocks, it is
3451 guaranteed to be non-contiguous.
3453 In mke2fs, print a warning message if a user tries to format a whole
3454 disk (/dev/hda versus /dev/hda1). If a user really wants to format a
3455 whole disk, the -F (force) option forces mke2fs to format a whole disk
3458 Fix a bug in fsck where in some cases it might start checking
3459 partitions in the next pass before it finishes checking partitions in
3460 the current pass. This still won't cause two partitions on the same
3461 disk will be checked, so it's rarely a problem in real life.
3463 Patch lsattr so that it won't hang when checking a named pipe.
3465 Minor compilation fixes:
3466 * Fix the order of libraries that were linked in debugfs.
3467 * Allow the sources to be compiled with -ansi turned on.
