Theodore Ts'o1daf7582004-01-31 22:33:16 -05001E2fsprogs 1.35-WIP (January 31, 2004)
2=====================================
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05003
Theodore Ts'o1daf7582004-01-31 22:33:16 -05004Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
5(the NLS library will replace "" with the .po header information).
6
Theodore Ts'oc4c30b22003-12-07 02:16:43 -05007Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
8dump due to a division by zero error. (Addresses Debian bug #207082)
9
Theodore Ts'o151a7162003-12-26 14:04:33 -050010Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
11when reconnecting a directory requires creating a lost+found
12directory. (Addresses Debian bug #219640).
13
14Fixed a bug where e2fsck would bomb out if a journal needed to be
15replayed when using an alternate superblock.
16
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050017E2fsck will give an extra grace period before actually forcing a check
18if the laptop is running on battery. The next time fsck runs while
19the system is on the AC mains, or after the grace period is exceeded,
20the filesystem will be checked. (Addresses Debian bug #205177)
21
22E2fsck will inform the user when there are 5 or fewer mounts before a
23filesystem check will be forced. (Addresses Debian bug #157194)
24
25Fix e2fsck's handling of corrupted indirect blocks in the bad block.
26We now correctly handle the case where there is an overlap between a
27block group descriptor or a superblock and a bad block indirect block.
28In the case where the indirect block is corrupted, we now suggest
29"e2fsck -c".
30
Theodore Ts'o1daf7582004-01-31 22:33:16 -050031Fix byte swap bugs in e2fsck that caused the journal backup location
32in the superblock and symlinks created by SE Linux to be cleared
33by e2fsck on big-endian machines. (Addresses Debian bug #228723)
34
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050035E2fsck -c now replaces the current list of bad blocks with the ones
36found by badblocks.
37
38Fix bugs in e2fsck and tune2fs which could cause a core dump if a
39non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
40
41Fix a potential bug in e2fsck which could cause it to core dump when
42trying to print the location of the backup superblock.
43
44Protect against a potential core dump in e2fsck when printing a
45message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -040046
Theodore Ts'o6826bde2003-08-21 02:14:44 -040047Add support for backing up the journal inode location in the
48superblock. E2fsck will automatically save the journal information in
49the superblock if it is not there already, and will use it if the
50journal inode appears to be corrupted. ext2fs_add_journal_inode()
51will also save the backup information, so that new filesystems created
52by mke2fs and filesystems that have journals added via tune2fs will
53also have journal location written to the superblock as well.
54Debugfs's logdump command has been enhanced so that it can use the
55journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050056
57E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -040058
59Shrink the size of the e2fsck executable by moving some initialized
60variables to the BSS segment.
61
62E2fsck will avoid printing the ^A and ^B characters which bracket the
63progress bar when stdout and stdin are a tty device instead of a pipe
64to another program. (Addresses Debian bug #204137)
65
Theodore Ts'o151a7162003-12-26 14:04:33 -050066Debugfs's mkdir command will automatically expand the directory if
67necessary. (Addresses Debian Bug: #217892)
68
69Fixed a bug in debugfs so that copying a file from /dev/null uses the
70correct mode bits. (Addresses Debian Bug: #217456)
71
72If the environment variables DEBUFS_PAGER and PAGER are not set,
73debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -050074/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -050075(Addresses Debian bug #221977)
76
77Chattr now stops processing options when it sees '--'. (Addresses
78Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -050079
Theodore Ts'o858dd7b2003-08-02 20:48:35 -040080Fix regression tests so they work correctly when e2fsprogs is compiled
81with configure --disable-htree.
82
Theodore Ts'o1daf7582004-01-31 22:33:16 -050083Fix bug in uuid library when there is no network card and the library
84is generating a time-based uuid. The random MAC address was not
85correctly generated to be a multicast address.
86
Theodore Ts'o858dd7b2003-08-02 20:48:35 -040087Add compile_et extensions from Heimdall that were missed the first time
88arounded.
89
90Fix bug in badblocks when using O_DIRECT; we need to make sure that
91we're reading from an offset which is page aligned. For read-only and
92read-write tests, we try to recover after an error so that we can
93continue reading on page-aligned boundaries. (Addresses Debian Bug
94#203713)
95
Theodore Ts'o151a7162003-12-26 14:04:33 -050096Updated and clarified various man pages. (Addresses Debian Bug
97#206845, #222606, #214920)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050098
Theodore Ts'o151a7162003-12-26 14:04:33 -050099Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400100
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400101Fixed various Debian packaging issues (see debian/changelog).
102
103Programmer's notes:
104-------------------
105
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500106Centralize code which calculates the location of the superblock
107and block group descriptors so that it is in a single library routine.
108
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400109Added two new functions, ext2fs_file_open2() and
110ext2fs_inode_io_intern2() which take a pointer to an inode structure.
111
112Fix compile_et to output the correct prototype for
113initialize_xxx_err_table_r() in the header file. (Addresses Debian
114bug #204332)
115
116In the lib/et makefile, make sure com_err.info is deleted on "make clean".
117
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400118Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
119present. This is for when we try stuffing an int into void * pointer.
120
121Fix type-punning which can cause gcc 3.x to miscompile code by getting
122confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
123and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
124**'. The EVMS code uses an ugly union approach since we don't want to
125modify the EVMS interfaces.
126
127Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
128aid build process on systems can use invoke GNU make as "gmake".
129
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500130Added regression testing for mke2fs.
131
132Fixed gcc -Wall nitpicks.
133
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500134Fixed various compiler warnings.
135
136Add portability fixes for FreeBSD and for using fsctl under Darwin to
137support ext2 ioctl's.
138
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400139
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400140E2fsprogs 1.34 (July 25, 2003)
141===============================
142
143Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
144a tight loop while waiting for a child fsck to exit in some cases.
145This burns CPU times which slows down the low-level filesystem check.
146
147Added code to mke2fs to assure that the default block size for a
148filesystem is at least as big as the sector size of the device, if it
149can be determined.
150
151Changed mke2fs and resize2fs to round the default size of a filesystem
152to be an even multiple of the VM pagesize in order to avoid a Linux
153kernel bug introduced when the storage of the buffer cache was moved
154into the page cache.
155
156Mke2fs will warn the user when creating a filesystem with journaling
157and a blocksize greater than 4096. (Addresses Debian bug #193773)
158
159Fixed a bug in resize2fs which caused it to fail on filesystems with a
160non-empty bad block list. Resize2fs now discards any blocks on the
161badblock list which are no longer part of the filesystem as the result
162of a filesystem shrink. (Note: this means that shrinking and then
163enlarging a filesystem is no longer a reversible operation;
164information about bad blocks in the part of the filesystem which is to
165be chopped off will be lost.)
166
167Changed resize2fs so the user can use prefixes to specify the units of
168the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
169and to make the error and informational messages explicitly display
170the blocksize used by the filesystem, in order to avoid confusion.
171(Addresses Debian bug: #189814)
172
173Added a new debugfs command, dump_unused, which dumps the contents of
174all unused blocks to stdout. (Useful as an emergency try-to-find
175deleted data command.)
176
177Added a new debugfs command, imap, which prints the location of a
178specified inode in the inode table.
179
180Fixed a bug in the badblocks program which caused it to use one bit of
181randomness in its non-destructive read/write test, instead of using a
182full 8 bits of randomness.
183
184Added a new option (-t) to badblocks, which allows the user to control
185the test pattern(s) used when checking a disk.
186
187The blkid probe function now more correctly detects UDF filesystems.
188
189Fixed a bug in the blkid library which caused it to not update its
190cache if a filesystem changes from having a label to not having a
191label.
192
193Fixed a bug in the blkid library wihch could avoid an infinite loop
194in blkid_find_dev_with_tag() if /proc is not mounted and there the
195/etc/blkid.tab file has not yet been created.
196
197Fixed the badblocks program so that the destructive read/write test
198honors the -c option, and to use O_DIRECT when possible to avoid
199thrashing the system block buffer cache.
200
201Fixed various NLS issues.
202 - Added Czech and Sweedish translations
203 - Removed testing NYC translation
204 - Fixed NLS support for message abbrevations in e2fsck
205 - Remove de-utf.po, since we shouldn't have two versions using different
206 charset encodings.
207 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
208 simplify the statistics reporting in e2fsck.
209
210Changed configure.in so that its defaults for *BSD systems no longer
211build an fsck wrapper, and not to install in /usr/local by default.
212
213Fixed some minor spelling errors/typo's in e2fsck and the configure
214script.
215
216Fixed various Debian packaging issues (see debian/changelog).
217
218Updated and clarified man pages. (Addresses Debian Bug #195616)
219
220Programmer's notes:
221-------------------
222
223Fix gcc -Wall nitpicks.
224
225Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
226NLS support by default. (Added partial workaround for gettext/Darwin
227incompatibility problems.)
228
229Added full MIT KRB5 and Himdall compaibility support to the com_err
230library and the compile_et program. (Addresses Debian bug #191900)
231
232Added the blkid_known_fstype() function to the blkid library, which
233returns true if it is passed a filesystem type which is recognized by
234the blkid probing functions.
235
236Improved the documentation for the blkid library.
237
238Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
239returns the hardware sector size of a device, if it is available.
240
241Added a dependency in the blkid library's .so file to the uuid
242library, since the former uses the latter. (Addresses Debian bug
243#194094)
244
245Added --with-diet-libc and --disable-evms to the configure script.
246
247Fixed a minor memory leak in the badblocks program.
248
249Fixed a portability problem in tune2fs --- not all systems have strptime().
250
251Fixed a portability problem in debugfs with the use of getopt() more
252than once. Old-style BSD, new-style BSD, and Linux C libraries all do
253things differently.
254
255Add support Windows support to ext2fs_get_device_size().
256
257Added (normally disabled) debugging code to the Unix I/O manager which
258causes it to disable all userspace caching if the NO_IO_CACHE is
259defined.
260
261Changed the test I/O manager so it can always be linked into e2fsck,
262mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
263configure script. The test I/O manager will only print any debugging
264information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
265variables are set, which specifies which I/O operations are logged and
266a block number to watch, respectively. The log messages are sent to
267stderr by default, unless a filename is specified via the
268TEST_IO_LOGFILE environment variable.
269
270
Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400271E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400272===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500273
Theodore Ts'oba142c12003-04-16 00:59:59 -0400274Added a new utility program, logsave, which captures the output of a
275command in a log file, even if the containing directory hasn't been
276mounted yet (in which case the it saves the output in memory until it
277can write out the logfile). This is useful for capturing the
278output of fsck during the boot sequence.
279
280Fixed some portability problems that were causing problems under
281the Cygwin32 environment.
282
283Mke2fs now interprets a negative number to the -b option as a minimum
284block size.
285
286Fixed a bug in mke2fs which was incorrectly checking the argument to
287the -g option if the default block size was used. (Addresses Debian
288bug #188319)
289
290Fsck now explicitly ignores tmpfs and devpts, and it will complain if
291it can not find filesystem checkers for jfs, reseirfs, and xfs.
292
293E2fsck now updates the global free block and inode counters from the
294block group specific counters quietly. This is needed for an
295experimental patch which eliminates locking the entire filesystem when
296allocating blocks or inodes; if the filesystem is not unmounted
297cleanly, the global counts may not be accurate.
298
299Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3002.0 is not yet supported; this only pulled in the bug fixes: fixed
301possible hangs caused by bugs in calling waitpid, and not setting the
302pipe to non-blocking mode; also fixed a file descriptor leak; made
303sure all functions call log entry/exit functions.)
304
305Badblocks now flushes its output file as bad blocks are discovered.
306
307The uuid library is now more paranoid about assuming the correctness
308of the /dev/random device; it mixes in a stream of bytes from
309random/srandom, just in case.
310
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500311Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -0400312maintainer of e2fsprogs. Other various Debian-specific packaging
313cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500314
315Move the source tarball generation functions from the top-level
316makefile to the util/gen-tarball script.
317
318Updated the Turkish .po translation file.
319
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500320Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500321it more compatible with com_err libraries from those distributions.
322
323Changed dumpe2fs to always display the superblock fields relating to
324the journalling and/or directory indexing feature even if those
325features are not enabled.
326
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500327Updated and clarify copyright statement vis-a-vis alpha releases of
328e2fsprogs.
329
330The ss library will now try to dynamically link to the readline
331library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -0400332the debugfs program now has line editing and history features. The
333SS_READLINE_PATH environment variable is used to find a readline or
334readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500335
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500336E2fsck now finds most duplicate filenames (all when rebuilding all
337directories via the -D option) and offers to delete or rename
338duplicate filenames/directory entries. (Addresses Debian Bug #176814).
339
340Fix bug in e2image. When writing out a raw image file, include data
341blocks from symlinks that do not store the symlink within the inode.
342
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500343Fix bug in resize2fs which incorrectly moved the block and inode
344bitmaps for sparse superblock filesystems and incorrectly marked
345blocks as in use. (Addresses Debian bug #174766)
346
347Added a new shared library, the blkid library, which efficiently
348allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
349and UUID filesystem specifiers without needing to search all of the
350devices in the system. Instead, the device is looked up in a cache
351file, and then verified to make sure the blkid cache is correct.
352
353Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
354the device name, using the blkid library. (Addresses Debian bugs
355#166048, #179671)
356
357Fsck now supports backslash escapes in /etc/fstab so that \040 can be
358used for spaces in device labels.
359
360Removed 32-bit limitations for debugfs's dump command.
361
362If the user specifies a large number of inodes, Mke2fs will
363automatically adjust the number of blocks per group to find a valid
364set of filesystem parameters.
365
366Add workaround to detect broken MD devices where when some of the
367underlying devices are marked read-only, writes to the MD device are
368silently dropped. E2fsck will detect if there is an attempt to run
369the journal twice, and abort with an error if this is the case.
370(Addresses IBM Bugzilla bug #1226)
371
372E2fsck will print an error if more than one of the -p/-a, -n or -y
373options are specified.
374
375E2fsck will fix HTREE corruptions in preen mode, without stopping the
376boot process. This is needed because the 2.4 ext2 filesystem
377accidentally had the INDEX_FL backwards compatibility code removed.
378
379Mke2fs no longer creates filesystems with the dir_index flag set by
380default; the user has to specifically request it.
381
382Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -0400383#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500384
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500385Created man page for the mk_cmds program (from the libss library).
386
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500387Programmer's notes:
388-------------------
389
390Fix various gcc -Wall nits.
391
392Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500393successfully under Solaris and Apple/Darwin.
394
395Fixed a Makefile dependency to allow building e2fsprogs using parallel
396make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500397
398Changes to create a subset distribution which consists only of the
399et, ss, uuid, and blkid libraries. The configure script and top-level
400makefile were changed to support working with a subset distribution.
401
Theodore Ts'oba142c12003-04-16 00:59:59 -0400402Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
403actually used, and might people who are looking for
404EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
405
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500406Updated debian files to fix a number of Lintian warnings.
407
408Updated config.guess and config.sub with newer versions from the FSF.

Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400410Removed unnecessary libraries from being linked into the fsck, lsattr,
411chattr, and blkid executables.

414==================================
415
416Fixed a bug in the Unix I/O routines which caused needless writebacks
417of clean blocks from the unix_io cache (they were erroneously marked
418as being dirty, so they were getting written back to disk before
419getting evicted from the disk cache). This was harmless, but it
420significantly slowed down e2fsck.
421
422Made some other minor optimizations to the Unix I/O routines to save a
423small amount of CPU time.
424
425Updated internationalization files.

429==================================
430
431Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
432compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
433handling for child process that die unexpectly. Add a hack to force
434mkfs to create filesystems that won't cause problems with hardware
435that has 2k or 4k minimum blocksize requirements. Read from child
436processes in non-blocking mode, so that the GUI continues to update.
437
438Fix e2fsck so that it returns the appropriate exit code when the root
439filesystem has been changed, so that system's rc scripts will be told that
440the system needs to be rebooted.
441
442Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
443was set, some of the descriptor blocks that should have been written
444out were getting skipped.
445
446Changed e2fsck to force out changes to the backup copies of the
447superblock and block group descriptors when important changes are made
448to those data structures.
449
450Fix a bug where e2fsck could erroneously mark a filesystem as being
451clean if a check of dirty filesystem is interrupted with a ^C. (Bug
452introduced in e2fsprogs 1.28.)
453
454If journal debuging is enabled using --enable-jbd-debug, the debugging
455level is now set via the E2FSCK_JBD_DEBUG environment variable.
456
457If byteswapping support is disabled using configure --disable-swapfs,
458skip the tests which depend on byte-swapping, so that "make check"
459won't bomb out.
460
461Lshattr will now display the indexed directory flag. Also, some of
462the more esoteric compression flags are supressed unless compression
463support has been enabled.
464
465Update man pages.
466

469=================================
470
471When resizing a filesystem, and inodes need to moved, resize2fs will
472update the inode's ctime field, and the mtime field of the containing
473directories, so that incremental backups using dump/restore will work
474correctly.
475
476In order to avoid spurious errors, e2fsck wil check the last
477superblock write time to determine whether or not it can safely use
478the LOW_DTIME checks to determine if there are inodes on the orphan
479inode linked list that had somehow gotten disconnected. (Addresses
480Sourceforge bug #620980)
481
482Partition in /proc/partitions that being with the string "lvm" are
483considered real partitions even if they do not end with a number.
484
485Fixed a bug in the the uuid generation function, where if /dev/urandom
486is not present, but /dev/random is, and there isn't sufficient
487entropy, the get_random_byte function could spin a loop forever.
488
489E2fsck, mke2fs, etc. will now reliably notice when image files are
490mounted using the loopback interface. (Addresses Sourceforge bug
491#619119)
492
493When flushing buffers (as is done by badblocks, for example) check to
494see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
495FDFLUSH ioctl which causes the MD device driver which causes confusing
496syslog messages about obselete ioctl messages. (Addresses Sourceforge
497bug #545832).
498
499Debugfs's write command now checks to see if the destination filename
500exists before creating it. (Addresses Sourceforge bug #478195.)
501
502When installing man pages, search for compressed man pages using all
503commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
504
505Fixed a bug in fsck where multiple filesystems specified on the
506command were not being checked in parallel due to a logic bug
507introduced to support the FSCK_MAX_INST environment variable.
508
509We have added a new superblock field, s_mkfs_time, which indicates
510when a filesystem was created. It is set via mke2fs, and printed out
511by dumpe2fs, but is not actually touched by the kernel.
512
513Dumpe2fs has been made more robust by not aborting if there is an
514error reading the block/inode bitmaps; instead it will still print out
515the location of the block/inode bitmaps and inode table.
516
517Add support for the an alternative block group descriptor layout which
518allows for on-line resizing without needing to prepare the filesystem
519in advance. (This is the incomat feature flag meta_bg.)
520
521Add support for storing default mount options in the superblock, so
522that the filesystem can be mounted with specific mount options without
523needing to specify them on the mount command line or in the /etc/fstab
524file.
525
526Add support for a new inode flag, which is to be used for indicating
527the top of directory hierarchies for the Orlov block allocator.
528
529Fix e2fsck so that if it creates the lost+found directory, it does so
530with the more apporpriate permissions of 0700. Also change
531mklost+found so that it also creates the directory 0700.
532
533Fixed format bug in e2fsck if NLS is in use.
534
535Add a German translation for e2fsprogs's NLS support.
536
537Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
538the beginning of the inode table. This won't matter much, since if
539there is a bad block at the beginning of the inode table, the root
540directory won't be available. But at least e2fsck won't crash in this
541case.
542
543Fixed endian problems in the htree code for e2fsck and debugfs.
544
545When byte-swapping a filesystem on a PPC architecture, byte-swap the
546bitmaps since the historical big-endian ext2 variant had byte-swapped
547bitmaps, and the ext2fs library assumes this. This fixes the
548regression test suite on PPC machines.
549
550Fix e2image so that it handles a bad block in the inode table
551appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -0400552
553E2fsck now uses a more sophisticated algorithm to salvage corrupted
554directories that recovers more information in the corrupted directory
555block.
556
557E2fsck now performs additional consistency checks on indexed (HTREE)
558directories.
559
560Fix bug where efsck might get confused about whether a completely
561empty directory block is an empty leaf block or an interior htree
562node. This could cause e2fsck to get confused into think that a valid
563indexed directory was corrupted.
564
565E2fsck no longer creates an empty directory entry at the end of a
566directory block when optimizing a directory. This would cause some
567earlier versions of the dxdir kernel code to corrupt the directory
568when attempting to split a node containing an empty directory entry.
569
570E2fsck could sometimes in rare circumstances leave the indexed flag
571set after a small directory was optimized by compressing it instead of
572indexing it. (This should never happen in real life, since
573directories that small wouldn't have been indexed, but better safe
574than sorry.)
575
576E2fsck now only updates the master superblock in all cases. This
577slightly shortens its run time.
578
579Ext2ed can deal with directory entries of length 0; previously it
580would get stuck in an infinite loop.
581
582Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
583specifiers. (Sourceforge patch #613447)
584
585Badblocks will now work correctly on read-only devices such as
586CD-ROM's. (Sourceforge patch #600451)
587
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500588Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -0400591E2fsprogs 1.29 (September 24, 2002)
592===================================
593
594Fixed a bug in e2fsck which could corrupt a directory when optimizing
595it (via the -D option) or rebuiliding the hash tree index with a 1 in
596512 probability, due to a fence post error.
597
598Fixed a bug in the LVM support code which caused LABEL='xxx' not to
599work correctly.
600
601Mke2fs now enables the directory indexing flag by default. (Since
602this is a compatible feature flag, it's safe to do so.)
603
604Tune2fs will support setting the directory indexing feature flag. It
605will automatically set up the default hash algorithm and hash seed
606fields in the superblock.
607
608If the bone-headed user enters the root filesystem twice in
609/etc/fstab, the -R option which skips the root filesystem will skip
610all of them. (Addresses Debian bug #159423). Note! This is not a
611precedent for dealing intelligently with any other kind of doubled
612entry in /etc/fstab!
613
614
615Programmer's notes:
616-------------------
617
618Removed perror declaration in lib/et/internal.h. All modern systems
619can be expected to define perror() these days. Besides, the lib/et
620code wasn't using perror at all anyway. :-)
621
622
Theodore Ts'ob7bad612002-08-31 03:00:33 -0400623E2fsprogs 1.28 (August 31, 2002)
624================================
625
626Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
627for setting the htree flag is not included yet, although it can be
628manually turned on via the debugfs program.
629
630Clarified e2fsck error message which is printed when it cannot find
631sufficient contiguous block when relcating filesystem metadata.
632
633Added support for building an EVMS plugin module for ext2/3. This
634module is substantially the same as the EVMS module shipping with EVMS
6351.1, with one or two bugfixes. E2fsprogs can also build this plugin
636for use with EVMS 1.0 (which did not include the ext2 plugin module),
637if the configure --enable-old-evms flag is given.
638
639Fsck will search through EVMS volumes when trying to resolve
640filesystem specifications such as LABEL=xxx or UUID=xxx.
641
642Added a new utility program, /sbin/findfs, which will return
643filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
644the device name.
645
646Update and clarified various man pages. (addresses Debian Bug #145044,
647#146437, #131350, #151990, #144621, #141938)
648
649If there are no filesystems specified on fsck's command line, fsck now
650treat that as if the -As options were given. Previously it would
651simply do nothing. (Addresses Debian Bug #153102)
652
653Mke2fs no longer treats a failure to be able to clear the MD signature
654at the end of the filesystem as a fatal error. (Addresses Debian Bug
655#155007)
656
657The e2p library functions (which are used by lsattr and chattr) now
658double check to make sure the file is a regular file or directory
659before attempting to use the ext2 ioctls. Some device drivers
660unfortunately respond to the ext2 ioctl's with unknown behaviour.
661(Addresses Debian Bug #152029).
662
663The extended attribute handling has been updated to correspond with
664the latest V2 bestbits ACL code.
665
666Fixed bug in e2fsck which caused it to not clear the dtime field when
667processing truncated inodes on the orphan list. This could cause data
668loss(!) if a filesystem is rebooted before a truncate has been
669committed.
670
671E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
672algorithms. This makes e2fsck much faster in the case of severely
673corrupted filesystems where a large number of blocks are claimed by a
674large number of inodes. (Thanks to the 2.5 IDE device driver for
675inspiring this work.)
676
677Resize2fs has been significantly sped up when shrinking and expanding
678a filesystem by a very small number of blocks (for example, when EVMS
679is converting a partition to be an EVMS legacy volume).
680
681Added a new option to e2fsck, -D, which will optimize or compress all
682of the directories in the filesystem.
683
684E2fsck now catches SIGINT and SIGTERM to make sure it will can
685properly clean up and only exit at safe points. Fsck will pass
686SIGINT/SIGTERM to its child processes, and wait until they have all
687exited before it exits.
688
689The uuid parsing code in the uuid library now properly complains when
690an illegally formated uuid is presented to it. (Addresses Debian bug
691#152891)
692
693Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
694and 2.4.17, since the workaround can cause problems when using a 2.4
695kernel with an old version of glibc built with the 2.2 headers.
696
697Fixed a bug in mke2fs where it wasn't properly clearing the initial
698superblock used by other filesystems. (Addresses Debian bug #147256.)
699
700Added support for the synchronous directory feature written by Andrew
701Morton.
702
703The debugfs program can delete directories using the rmdir command.
704
705Add support for 8k and 16k filesystems (for systems with page sizes
706that are greater or equal to 8k or 16k, respectively). Note that
707these filesystems can not be mounted on x86 systems, or other systems
708with only 4k page sizes, due to limitations in the current Linux VM
709code.
710
711Resize2fs requires that the filesystem state be valid and have no
712errors; otherwise, e2fsck -f must be run first. (Previously it simply
713required that the last fsck time be greater than the last mount time.)
714
715Configure now defaults the man pages directory to /usr/share/man on
716Linux systems.
717
718E2fsck now offers to truncate inodes which contain too many blocks (so
719that i_blocks would overflow. Also fixed handling of large sparse
720files.
721
722E2fsck now more completely checks for symlink validity, including
723requiring NULL termination and length checks.
724
725E2fsck will offer to try forcing a disk write to remap a bad block
726after finding a read error when reading a filesystem metadata block.
727
728Fixed a bug in debugfs which caused the -b and -s options to crash
729debugfs, as well as breaking the testb, setb, and clearb functions.
730
731Added a bmap command to debugfs which calculates the logical to
732physical block mapping for a particular inode.
733
734Fixed a bug in code which checked to see if a device was mounted which
735sometimes (rarely) failed in the case of a plain file.
736
737Fixed a bug in resize2fs where when it reported an error, it would
738print a message erroneously indicating that the filesystem had been
739resized before it aborted.
740
741When resizing a plain file which is smaller than the requested size,
742resize2fs will attempt to extended the file so that programs like
743e2fsck will not complain that the file is too small.
744
745Resize2fs will print the actual new size of the filesystem when it is
746finished resizing.
747
748Fixed a bug in debugfs where "ls -l" would report incorrectl file type
749information on big-endian systems.
750
751
752Programmer's notes:
753-------------------
754
755Fixed collisions with C++ reserved words.
756
757Added portability fixes for building e2fsprogs on the HURD and AIX.
758
759Added the ext2ed program for creation of test cases. (ext2ed has many
760limitations and bugs which make it unsuitable for production use.)
761
762The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
763flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
764name_len field is byte swampped on big-endian machines, since in the
765V2 structure, name_len is a char field which is doesn't need to be
766byte swapped --- except if an old-style kernel had byte-swapped the
767name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -0500770E2fsprogs 1.27 (March 8, 2002)
771==============================
772
773The warning messages for mke2fs now go to standard error.
774
775Fixed to make sure "make check" runs all of the test programs with
776LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
777
778The mke2fs program checks the boot sector for the BSD disk label, and
779avoids erasing it if it is there.
780
781Fixed a bug in e2fsck which caused it to core dump if the journal
782inode was missing when it was supposed to be there.
783
784E2fsck now prints ranges in pass 5 when printing deltas for the block
785and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500786
787Debugfs's "ls -l" command now will print out the file type information
788in the directory entry.
789
790Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
791mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
792
793Debugfs can now examine the experimental directory indexing
794information.
795
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500796Fixed bug in debugfs which caused it to core dump if modify_inode is
797called without an open filesystem.
798
799The debugfs lsdel command now runs its output through a pager first.
800
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500801When installing manual pages, remove the compressed manual pages first.
802
803Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
804
805Fix the 2.4 resource limitation workaround introduced in 1.26 which
806actually broke things on mips32, sparc32, and Alpha platforms.
807
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500808Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
809(which is required by the newer libintl libraries).
810
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500811Programmer's notes:
812-------------------
813
Theodore Ts'oa8e77242002-03-08 03:12:14 -0500814Fixed various gcc -Wall complaints.
815
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500816Fixed a few memory leaks in the e2fsck journaling code, and in the
817ismounted code checking for a swap device.
818
819Add new inode I/O abstraction interface which exports an inode as
820an I/O object.
821
822Exported ext2_file_flush as a public interface.
823
824In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
825
826Lots of small random portability fixes to make e2fsprogs build under
827AIX --- even without the 5L compatibility toolkit, and even using the
828uber-crippled AIX native C compiler.

Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500832=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500833
Theodore Ts'o446314f2001-12-24 15:22:27 -0500834Dumpe2fs will keep going now if the bad block inode can't be read.
835(Previously it stopped with a fatal error.)
836
837E2fsck will now give an opportunity to run the journal even if the
838recovery flag is not set. This is the default behaviour if e2fsck is
839using a backup superblock, since the needs_recovery flag will never be
840set in the backup superblock copies.
841
842E2fsck now automatically finds the backup superblock/group descriptors
843even when the primary superblock is completely destroyed for 2k and 4k
844filesystems. (Previously it just guessed/assumed that we were dealing
845with a 1k filesystem in that case, and users had to manually specify
846the backup superblock number.)
847
848Fixed a bug in e2fsck where it dereferences a null pointer when there
849is a problem opening a filesystem in preen mode.
850
851E2fsck now handles external journals correctly; previously it trashed
852the external journal device if the journal needed to be replayed.
853
854Work around ulimit incompatibility problem caused by recent 2.4
855kernels; the unix IO module will automatically try to set any resource
856limits to be infinite on startup.
857
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500858Fixed a bug in e2fsck where it wasn't allocating a new block or inode
859bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400860 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500861
862E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
863clearing the new V2 fields if they do not make sense or if the ext3
864superblock is version 1 superblock.
865
866E2fsck will automatically relocate the ext3 journal from a visible
867file (i.e., /.journal) to an hidden inode if the filesystem has been
868opened read/write. This allows the users to add a journal while the
869filesystem is mounted, but the next time the system is rebooted, the
870journal file will disappear. This avoids problems with backups,
871stupid operators with superuser bits, etc.
872
873Fix a bug in fsck where it would not support a filesystem type of
874"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
875
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500876Fsck now supports fstab entries of the form "ext3,ext2". It will also
877automatically identify reiserfs filesystems.
878
879The number of processes spawned by fsck can now be limited using the
880FSCK_MAX_INST environment variable.
881
Theodore Ts'o446314f2001-12-24 15:22:27 -0500882Fsck now searchs the LVM proc hierarchy to find logical volumes which
883should be searched for UUID and label information.
884
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500885Work around a bug in 2.4.10+ kernels by trying to unset the filesize
886limit if at all possible, when opening a block device. (The filesize
887limit shouldn't be applied against writes to a block device.)
888
Theodore Ts'o446314f2001-12-24 15:22:27 -0500889In mke2fs and e2fsck, specifying the -c option twice will now do
890a read/write test on the disk. Update the man pages to encourage
891using the -c option, and to discouraging running badblocks separately,
892since users tend to forget to set the blocksize when running
893badblocks.
894
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500895Mke2fs now automatically clears the immutable attribute on a
896pre-existing .journal file left over from a previous failed attempt to
897add a journal to an alreadyy-mounted filesystem.
898
899Fixed mke2fs's exit codes to consistently indicate when the mke2fs
900operation failed.
901
Theodore Ts'o446314f2001-12-24 15:22:27 -0500902Mke2fs now creates the lost+found directory with permissions of 0700,
903so that files that had previously lived in protected directory are
904safe if they get dropped in lost+found and the system administrator
905doesn't deal with immediately. (Addresses Debian #bug 118443)
906
907Mke2fs and e2fsck (and all programs that use the
908ext2fs_check_if_mounted function) will now properly identify that a
909device is mounted, even in cases where devfs has confused things with
910multiple devices names with the same identity, or if a dim-witted
911system administrator has done something stupid like creating device
912file aliases in their home directory. Also now checks for swap devices
913by using /proc/swaps. (Addresses Debian bug #106622)
914
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500915Added a new option (-T) to tune2fs which sets the time a filesystem
916was last checked.
917
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500918Speed up e2image when creating sparse raw image files by optimizing
919away excess lseek() system calls.
920
921Fix support of large (> 2GB) files when used as a filesystem in
922mke2fs, tune2fs, debugfs, and findsuper.
923
924Debugfs's stat and icheck commands now properly deals with large (>
9252GB) files.
926
927Debugfs's set_super_value command now prints out the list of valid
928superblock fields which can be set using the command.
929
Theodore Ts'o446314f2001-12-24 15:22:27 -0500930Debugfs's rm and kill_file command now updates the superblock free block
931and inode counts, thus keeping the filesystem consistent.
932
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500933Debugfs's lsdel command now takes an optional argument which allows
934the user to only see the most recently deleted files.
935
936A new command (undel) was added to debugfs which automates
937undeleting a deleted inode and linking it back to a directory.
938
939Debugfs's ls command now takes a new option, -d, which lists
940deleted directory entries.
941
942Debugfs's testb, freeb, setb, and find_free_block commands now take an
943optional count argument.
944
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500945Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
946be used to signal that a particular inode should not be eligible for
947tail-merging --- this is needed for programs like LILO.
948
949The findsuper (an unreleased, uninstalled utility program) has been
950improved to add extra validity checks and to add a progress meter.
951(It is still an unsupported program; the officially supported way to
952recover from a trashed partition table is to use gpart; findsuper is
953for wizards only. :-)
954
955Debugfs was fixed to compile with "configure --disable-swapfs".
956
Theodore Ts'o446314f2001-12-24 15:22:27 -0500957Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500958
959Added new translation file for Turkish.
960
Theodore Ts'o446314f2001-12-24 15:22:27 -0500961Programmer's notes:
962-------------------
963
964Fix general gcc -Wall complaints.
965
966E2fsprogs (mostly) works with the dietlibc.
967
968The programming texinfo file has been expanded to include description
969of additional libext2fs functions. (Still not compeltely done, but a
970lot of the more important functions have been documented.)
971
972Added a umask structure to struct_ext2_filsys, which currently only
973modifies the behaviour of ext2fs_mkdir(), but if we add any file
974creation functions to libext2fs, we should also make sure they respect
975the umask setting.
976
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500977The build-rpm script was fixed to be a bit more safe.
978
979The tests' Makefile now has a way of automating test case creation
980for e2fsck, using "make testnew".
981
982Created a new function, ext2fs_dir_iterate2 which passes more
983information to the callback function (identical to the one used by
984ext2fs_dblist_dir_iterate). The directory iterator functions take a
985new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
986directory entries. If the directory entry is deleted, the callback
987function will be called with the entry paraemter set to
988DIRENT_DELETED_FILE.
989
990Added new functions, ext2fs_inode_alloc_stats and
991ext2fs_block_alloc_stats, which takes updates block/inode allocation
992statistics in the bitmaps, block group descriptors, and superblock
993when inodes or blocks are allocated or deallocated.
994

Theodore Ts'od08a4ce2001-09-20 09:47:42 -0400996E2fsprogs 1.25 (September 20, 2001)
997===================================
998
999This is primarily a bug-fix release; no new features were added, but
1000there are a number of embarassing bug fixes and cleanups applied.
1001
1002Fix a bug mke2fs which causes stack garbage to be written to disk when
1003zapping disk sectors. (This bug could cause mke2fs to core dump for
1004some kernels, I suspect with security enhancement patches.)
1005
1006Remove unneeded #include of <linux/config.h> which was breaking
1007building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1008
1009Updated tune2fs man page to reflect the fact that adding or removing a
1010journal doesn't require running e2fsck.
1011
1012Remove use of AC_REQUIRE from autoconf which had been used to prevent
1013AC_CANONICAL_HOST from being called twice; unfortunately this causes
1014recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1015used outside of autoconf macros. Fortunately, it doesn't seem to be
1016necessary any more, anyway.
1017
1018E2fsck will now not fall back to an alternate superblock if the user
1019specifies the superblock location explicitly on the command-line.
1020This allows easier recovery from a situation where the primary
1021superblock and block groups are slightly corrupted, but the backup
1022superblocks are completely broken.
1023
1024Fix problem which caused compile_et and mk_cmds to blow up if
1025e2fsprogs was in a directory with a pathname that contained spaces.
1026
1027We are now more paranoid about checking the entry in /etc/mtab to make
1028sure the filesystem is really mounted, since some broken distributions
1029(read: Slackware) don't initialize /etc/mtab before checking non-root
1030filesystems. (Slackware also doesn't check the root filesystem
1031separately, and reboot if the root filesystem had changes applied to
1032it, which is dangerous and broken, but there's nothing I can do about
1033that.)
1034
1035Make UUID library C++ friendly by adding appropriate extern "C"
1036declarations and using const in the function declarations.
1037
1038Fix up the com_err texinfo file so that it can product a valid info
1039file (previously, it could only be used to generate paper
1040documentation using texinfo.tex).
1041
1042
Theodore Ts'ofb707752001-09-04 15:00:37 -04001043E2fsprogs 1.24a (September 2, 2001)
1044===================================
1045
1046Fix brown-paper bug in mke2fs which caused it to segfault when
1047printing the version string.
1048
1049
Theodore Ts'o109624a2001-08-31 00:59:55 -04001050E2fsprogs 1.24 (August 30, 2001)
1051================================
1052
1053Revert the BLKGETSIZE64 support, since for some distributions, this
1054ioctl has been used by an unofficial kernel patch to update the last
1055sector on the disk, and this was causing disk corruption problems as a
1056result.
1057
1058Mke2fs is now more careful about zapping swap space signatures and
1059other filesystem/raid superblock magic values so that programs like
1060mount who try to use hueristics to determine the filesystem type of a
1061partition are less likely to be confused.
1062
1063E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1064regular file (since Andreas Dilger's on-line resizing tools will set
1065its mode bits).
1066
1067Fixed some minor texinfo, man pages nits for spelling errors,
1068texinfo warnings, etc. (Addresses Debian bug #110621.)
1069
1070E2fsprogs program no longer print the filesystem version number
1071(i.e. 0.5b), since it only confuses people and doesn't serve any real
1072purpose.
1073
1074E2fsck will once again compile under libc5, since it will supply its
1075own version of strnlen if necesssary.
1076
1077mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1078when specifying the external journal device. tune2fs will also search
1079devices looking for the externla journal debice when removing.
1080
1081E2fsprogs 1.23 (August 15, 2001)
1082================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001083
1084Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001085correctly handle a filesystem with EA's and check the EA blocks for
1086corruptions.
1087
Theodore Ts'od494bba2001-08-09 06:14:42 -04001088E2fsck's symlink sanity checking has been cleaned up. It now checks
1089the i_size value of fast symlinks, and checks for immutable flags
1090being set of symlinks, etc.
1091
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001092E2fsck now offers to clear inodes which are special files that have a
1093non-zero i_blocks or i_size field. (The i_size field check was in the
1094previous version of the code, but due to a bug it didn't offer to
1095clear the inode unless i_size and i_size_high were both non-zero.)
1096
Theodore Ts'od494bba2001-08-09 06:14:42 -04001097E2image can now create "raw" image files, which only contain the
1098filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1099debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001100
1101Add support for the 64-bit block device patches.
1102
1103Fixed bugs in creating external journals with a 1k blocksize.
1104
Theodore Ts'od494bba2001-08-09 06:14:42 -04001105Add initial support for external journals (so long as the external
1106journal only supports a single filesystem) in e2fsck.
1107
1108Remove requirement for needing to run fsck on a filesystem after
1109removing a journal (either internal or external).
1110
Theodore Ts'obf16d102001-07-27 22:20:06 -04001111The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001112
1113Speed up the check of an ext3 filesystems by avoiding a needless flush
1114of all of the superblock and block group descriptors.
1115
Theodore Ts'od494bba2001-08-09 06:14:42 -04001116Speed up creating an internal journal using tune2fs in the case where
1117the filesystem has a lot blocks already allocated.
1118
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001119Tune2fs has been fixed to make sure that only error messages go to
1120stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1121
Theodore Ts'od494bba2001-08-09 06:14:42 -04001122Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001123now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04001124
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001125Add support in fsck for the filesystem type "auto".
1126
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001127Fsck -A will not try to interpret device names for filesystems which
1128have a pass number is 0. (Addresses Debian bug #106696).
1129
1130Fsck prints a warning message if now valid filesystems are passed to
1131it. (Addresses Debian Bug #107458.)
1132
Theodore Ts'o9249d982001-07-20 18:14:10 -04001133E2fsck now gives an explicit warning if there filesystem still has
1134errors at the end of the run. (Addresses Debian bug #104502)
1135
Theodore Ts'od494bba2001-08-09 06:14:42 -04001136E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001137reflects an error. E2fsck will also not run the orphan list if the
1138filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04001139
1140E2fsck now prints the number of large files when given the -v option.
1141
1142Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001143
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001144Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04001145
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001146
Theodore Ts'o19d6b542001-06-23 00:13:09 -04001147E2fsprogs 1.22 (June 22, 2001)
1148==============================
1149
1150Fixed a bug in e2fsck's handling of orphan inodes which are special
1151files (i.e., block/character device files, named FIFO's, etc.).
1152
1153Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1154tune2fs to fail at adding a journal to a mounted filesystem.
1155
1156Fixed a few big-endian bugs in e2fsprogs
1157 * The directory block functions were accidentally reporting
1158 some directories as corrupted when they weren't.
1159 * If e2fsprogs is compiled --disable-swapfs, the C language
1160 equivalents weren't being included for big-endian platforms.
1161 (Fixes Debian bug #101686).
1162
1163Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1164
1165Programmer's notes:
1166-------------------
1167
1168Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1169ioctls, and allow them to be defined for non-i386 platforms.
1170
1171The uuid.h header file is now protected against multiple inclusions.
1172
1173E2fsprogs is now being developed using BitKeeper. Changed the test
1174scripts to deal with BK's stripping CR characgters from text files,
1175and changed the top-level Makefile.in to avoid including BitKeeper
1176files when generating the source tarball.
1177
1178
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001179E2fsprogs 1.21 (June 15, 2001)
1180==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00001181
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001182Added new configure flags which allow a subset e2fsprogs to be built;
1183this is most useful for boot floopies, since the resulting shared
1184libraries and programs are slimmed down by removing features that
1185aren't necessary for a boot floppy. The new flags that were added
1186are: --disable-swapfs, which removes support for byte swapping old
1187legacy PPC/68k filesystems, --disable-debugfs, which removes support
1188for debugfs from the libext2fs library, --disable-imager, which
1189removes support for the e2image program, and --disable-resizer, which
1190removes support for resize2fs.
1191
1192E2fsck now prints the number of mounts or days elapsed since the last
1193check when e2fsck is forced to check an otherwise clean filesystem.
1194
1195Tune2fs now prints an informative message about how often a filesystem
1196will be checked when adding a journal to the filesystem, to remind the
1197user that he/she may want to adjust those parameters using tune2fs
1198-c/-i.
1199
1200Worked around hurd brain-damage which causes e2fsck to sometimes
1201believe a filesystem is the root filesystem based on device numbers
1202(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1203violation).
1204
1205Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1206erroneous error with the -F option was specified.
1207
1208Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001209ext3 0.7a.
1210
Theodore Ts'o767de092001-06-02 01:20:18 +00001211Fixed two bugs in e2fsck's handling of dup block handling, dealing
1212with relatively uncommon edge cases: a directory with an indirect
1213block which is claimed by another file, and when the last inode in the
1214filesystem has blocks claimed by another file.
1215
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00001216E2fsck now checks to see if the i_size field of a fast symlink is too
1217big, and offers to clear the symlink if so.
1218
1219E2fsck now checks to see if i_size_high of special files is non-zero,
1220and offers to clear i_size_high.
1221
Theodore Ts'o767de092001-06-02 01:20:18 +00001222Fix e2fsck's handling of incompatible journal flags so that the user
1223has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00001224entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00001225
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001226Fixed a bug in fsck which could cause it to core dump if a mix of
1227standard and non-standard device names are used in /etc/fstab.
1228(Debian bug #100559)
1229
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001230Fixed a bug in debugfs which caused read errors when copying a file to
1231not be noticed.
1232
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001233The debugfs set_super_value command can now modify the s_lastcheck field.
1234
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001235Fixed a bug in lsattr and chattr which was accidentally introduced in
12361.20 to support > 2GB files; both lsattr and chattr wasn't reading
1237directories correctly because the change modified the layout of struct
1238dirent to be incompatible with the libe2p shared library.
1239
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001240Cleaned up the mke2fs manual page and included a discussion about why
1241it's good to periodically check the filesystem even when journaling is
1242enabled.
1243
Theodore Ts'o767de092001-06-02 01:20:18 +00001244Programmer's notes:
1245-------------------
1246
1247Fix general gcc -Wall complaints.
1248
1249The types needed by the ext2 header files are now provided by
1250lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1251
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001252Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001253in ext2_types.h. Also, if linux/types.h has already been defined,
1254don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001255
Theodore Ts'o767de092001-06-02 01:20:18 +00001256Fixed make depend script so that it automatically corrects the
1257pathname cleanups performed by make -M, so I don't have to fix them up
1258by hand.
1259
1260Fixed the d_loaddump test case to be more robust, and not depend on
1261bash'isms.
1262
1263Removed debugfs's dependence on pread(), which was accidentally
1264intrudced in e2fsprogs 1.20
1265
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001266Fixed a performance bug in the libext2fs's icount routine; the size
1267estimate of the icount array was incorrectly being calculated.
1268
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001269Removed use of the badblocks compatibility functions in the e2fsprogs
1270programs.
1271
1272Added paranoia code which protects against strange cases where /etc
1273isn't on the root filesystem, or if /etc/mtab doesn't exist.
1274
1275The header file ext2_types.h is now installed.
1276
1277Autoconf is used to determine when we are on big-endian machines,
1278instead of doing run-time tests, to save a few bytes of code.
1279
1280The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1281functions are no longer inline functions, which saves space and
1282doesn't really cost any real performance.
1283
1284The ext2fs library no longer depends on the e2p library. (What need
1285there was of it --- namely, fsetflags, was coded in-line).
1286
1287Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
1288when the user is stupid and tries compiling the package using "make
1289install" as root.
1290
1291Miscellaneous code cleanups:
1292 * Added missing files from Makefile.in's SRCS file, so that
1293 their dependencies would be properly calculated.
1294 * Removed redundant code
1295 * Fixed comments in code
1296 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001299E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001300=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00001301
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001302Add support for replaying the ext3 journal purely in user mode,
1303including handling the orphaned inode list. Used code contributed by
1304Andreas Dilger, with bug fixes and the orphaned inode handling done
1305by Theodore Ts'o.
1306
1307The mke2fs and tune2fs programs can create or modify a filesystem to
1308include an ext3 journal. Tune2fs also can be used to remove an ext3
1309journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001310
1311E2fsck will now check for the existence of a linked list of orphan
1312inodes in the superblock, and clear those inodes before starting the
1313rest of the filesystem check (but after the journal playback).
1314
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001315E2fsck now validates the file descriptor passed to the -C option,
1316which saves against the completion bar getting written to an
1317unexpected location, such as the disk being checked. (Debian
1318bug/wishlist #55220)
1319
1320E2fsck will now bump the filesystem revision number from zero to one
1321if any of the compatibility bits are set.
1322
1323Fixed a bug where a badly corrupted directory on a big endian system
1324could cause e2fsck to die with a bus error. The
1325ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
1326the ext2 library now does alignment sanity checks on the rec_len field
1327of the directory entry before using it.
1328
1329The ext2 library has been enhanced to make tune2fs safe to run on
1330mounted filesystems. (Users could usually get away with using tune2fs
1331on mounted filesystems before, but with the advent of ext3 and
1332journaling, it became important to make tune2fs was *really* safe for
1333use even when the filesystem being modified is mounted.) E2label is
1334now implemented by tune2fs using an argv[0] dispatch, so that e2label
1335is also now safe for use on mounted filesystems.
1336
1337Added a new program, e2image, which creates a backup of critical ext2
1338filesystem data structures. The generated image file can be examined
1339using dumpe2fs and debugfs. In the future, e2fsck will be able to use
1340the image file to help recover very badly damaged filesystems.
1341
1342Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
1343no longer cause e2fsck to bomb out. Also treat files > 2GB as being
1344large file when deciding whether or not the filesystem has large files.
1345
1346Fixed lsattr and chattr so that they work correctly on large files.
1347(Fixes Debian bug #72690.)
1348
1349Removed limitation in get_device_size() which imposed a one terrabyte
1350filesystem limitation. (Most 2.2 kernels still have a signed int
1351problem which cause 1 TB block device limitation. Fortunately, the
1352kernel patches to fix this are much easier than fixing the 2TB
1353limitation in the kernel. :-)
1354
1355A max_mount_count of zero is now treated as if no mount count were
1356set. (Previously, no mount count was indicated by using -1, and a
1357mount count of zero caused e2fsck to always be run.)
1358
Theodore Ts'o77648562001-05-14 13:04:44 +00001359Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001360
1361Mke2fs now adds some randomness in s_max_mount_count so that multiple
1362filesystems won't be all checked at the same time under normal
1363operations.
1364
Theodore Ts'o5570a652000-08-21 01:23:39 +00001365Fixed bug in the progress bar printing code which could cause e2fsck
1366to core dump on an illegal filesystem.
1367
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001368Fixed bug in fsck which could allow more than one instance of e2fsck
1369to be printing a progress bar. (Debian bug #65267)
1370
Theodore Ts'o5570a652000-08-21 01:23:39 +00001371Fsck using a UUID or a LABEL specifier will work even if devfs is
1372compiled into the kernel and not mounted. If the pathnames in
1373/proc/partitions are incorrect, fsck will search /dev for the correct
1374device (using the new ext2fs_find_block_device library function).
1375Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001376found when they are in use. Support has also been added to support
1377additional IDE disks and the DAC 960 device names. (Debian bug #94159)
1378
1379Fixed a bug in fsck which caused it not deal properly with 16
1380byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001381
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001382Fsck's -t option has been made a lot more flexible. The semantics for
1383what happens if a comma-separated list to fsck has been regularized,
1384and it is now possible to filter what filesystems will get checked
1385based what is in the filesystem's fstab entry's option field. (Debian
1386bug #89483.)
1387
Theodore Ts'o5570a652000-08-21 01:23:39 +00001388The dumpe2fs program can now print out the group description
1389information in hex, and also prints the location of the superblock and
1390block group descriptor for those block groups that have them.
1391
1392Mke2fs now clears the ext2 superblock before it starts creating a
1393filesystem, so that the superblock magic number is only written if the
1394filesystem creation process successfully completes.
1395
1396The debugfs program's stat command now pretty-prints the blocks used
1397by an inode so that it's more compact and informative.
1398
1399The debugfs stats command now uses the same libe2p code (which is used
1400by dumpe2fs) to print the superblock header information. This is more
1401complete, and it avoids a bit of code duplication.
1402
1403Added a new debugfs command, set_super_value (ssv) which allows the
1404user to set arbitrary superblock fields.
1405
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001406Debugfs was extended to support inode numbers in hex (by prefixing
1407them with 0x), and so that modify_inode can set the inode generation
1408number. Also, there is now a new function command called logdump
1409which will dump an ext3 journal.
1410
1411Fixed a bug in debugfs so that quitting out of the pager doesn't kill
1412debugfs.
1413
1414Debugfs's dump command now stops immediately upon reporting a disk
1415read error. (Fixed a bug in ext2fs_file_read library routine which
1416caused debugfs not to stop.) (Debian bug #79163)
1417
1418On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
1419checked before /etc/mtab is used, since /proc/mounts is more likely to
1420be accurate.
1421
1422Added portability fixes for Solaris and Linux/ia64.
1423
1424Various manual pages were clarified and cleaned up. (Fixed debian
1425bugs #63442, #67446, and #87216)
1426
Theodore Ts'o5570a652000-08-21 01:23:39 +00001427
1428Programmer's notes:
1429-------------------
1430
1431The e2fsck message printer now supports %Iu and %Ig, which will print
1432out the inode's user and group owners, respectively.
1433
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001434E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
1435that no longer dependent on the system having the correct version of
1436the kernel header files.
1437
Theodore Ts'o5570a652000-08-21 01:23:39 +00001438Added a new function to libext2, ext2fs_find_block_device(), which
1439searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
1440device given its device number.
1441
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001442Added a new function to libext2, ext2fs_sync_device, which centralizes
1443all of the places which might try to use the BLKFLSBUF or FDFLUSH
1444ioctls (and usually failing to define them since the system header
1445files don't usually do this for us, and we're trying to avoid usage of
1446kernel include files now).
1447
Theodore Ts'o5570a652000-08-21 01:23:39 +00001448Added new utility programs in tests/progs: random_exercise and
1449hold_inode. They aren't built by default; they're useful for
1450exercising ext3 filesystem code.
1451
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001452Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
1453the filesystem close functions to only update the superblock, and to
1454not touch the block group descriptors. Needed by tune2fs when
1455modifying a mounted filesystem.
1456
1457Got rid of struct ext2fs_sb and replaced it with the standard struct
1458ext2_super_block from include/linux/ext2_fs.h. Note: this may break
1459source (but not binary) compatibility of some users of the ext2
1460library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00001461replace of struct ext2fs_sb with struct ext2_super_block, and include
1462the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001463
1464The ino_t type has been renamed ext2_ino_t to protect applications
1465that attempt to compile -D_FILE_OFFSET_BITS=64, since this
1466inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
1467unexpected ABI change.
1468
1469The Makefiles have been reworked so that "make check" can be run from
1470the top-level Makefile.
1471
1472Fix general gcc -Wall complaints and removed dead code.
1473
1474Remove use of NOARGS, because we assume everyone does ANSI C these
1475days.
1476
1477Added build-rpm script from sct.
1478
1479New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
1480to support e2image.
1481
1482New function ext2fs_flush_icache which must be called if the
1483application program modifies the inode table blocks without going
1484through ext2fs_write_inode() interface.
1485
1486New ext2fs_check_mount_point() function, which will return the mount
1487point of a device if mounted.
1488
1489The io_channel abstraction now has an optional interface,
1490io_channel_write_range, which allows specific byte ranges to be
1491written.
1492
1493The unix_io IO channel now supports write-through caching, so that
1494journal creation is more efficient.
1495
1496Added x86 assembly language routines to support byte swapping, to
1497reduce executable size.
1498
1499Fixed bug in the utility program subst so that it's possible to
1500replace a substitution variable with a zero-length string.
1501
1502Fixed numbering e2fsck pass1 problem numbers; an extra zero had
1503slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001504
Theodore Ts'ob777e262000-07-27 01:39:23 +00001505E2fsprogs 1.19 (July 13, 2000)
1506==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00001507
1508Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00001509be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00001510
1511Add experimental support needed for the ext2 compression patches.
1512This requires compiling e2fsprogs with the --enable-compression flag
1513to the configure script.
1514
1515Added ext3 journalling support. E2fsck will run the journal (if
1516necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
1517installed as a symlink to e2fsck. Fsck has been taught about ext3,
1518and treats it the same as ext2 in terms of the progress bar logic.
1519Dumpe2fs will display the superblock journaling information if the
1520filesystem has a journal. The ext2 library will now permit opening an
1521ext3 filesystem with the recovery flag set. This is necessary for
1522on-line dump's to work correctly, but there may be issues with this
1523working well since ext3 is much less agressive about syncing blocks to
1524the filesystem, since they're safe on the journal.
1525
1526Tune2fs and e2fsck have been changed to allow the mount_count check to
1527be disabled by setting max_mount_count to -1. (This was already
1528supported by the kernel.)
1529
1530Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
1531are used for ext3 as well.
1532
1533Added internationalization support for e2fsprogs; must be enabled
1534by passing --enable-nls to configure.
1535
1536Always use the provided ext2fs header files to insulate ourselves from
1537kernel version changes. Which include files are used by e2fsprogs
1538have also been cleaned up to improve portability.
1539
1540Limit the number of times that e2fsck updates the progress bar so that
1541people who are booting using a 9600 baud console don't get swampped by
1542too many updates.
1543
1544Improved the loop detection algorithm in e2sck's pass #3 so that it is
1545much, much faster for large filesystems with a large number of
1546directories.
1547
1548The memory footprint for e2fsck is now slightly smaller than before.
1549
1550E2fsck now checks if special devices have a non-zero size, and offers
1551to clear the size field if it finds such an inode.
1552
1553E2fsck now checks if special devices have the append-only flag set,
1554and offers to clear the inode.
1555
1556E2fsck now properly handles some "should never fail" cases during a
1557bitmap copy in pass5.
1558
1559E2fsck now properly prints control characters in filenames as ^A .. ^Z.
1560
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001561E2fsck now calculates the correct location of the backup superblock in
1562the case of filesystem blocksizes > 1k.
1563
1564Fixed a bug in e2fsck's calculation of the number of inodes_per_block
1565which normally didn't cause problems under most filesystem parameters,
1566but could cause a valid superblock to be rejected in extreme cases.
1567Other checks for validating superblock values were made more
1568stringent.
1569
Theodore Ts'oab146762000-07-07 04:37:35 +00001570Added non-destructive write testing to the badblocks program, courtesy
1571of David Beattie. The badblocks also now has an option to input the
1572current set of bad blocks, so that known bad blocks are skipped to
1573speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00001574feature which causes badblocks to run until it has completed some
1575number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00001576
1577Badblocks now checks to see if the device is mounted and refuses to do
1578the tests involving writing to the device if it is mounted. Also,
1579badblocks now allows the number of blocks to be checked to be
1580defaulted to the size of the partition.
1581
1582Fixed a bug in fsck which didn't allow non-root users to be able to
1583check filesystems if there were any LABEL= or UUID= entries in
1584/etc/fstab.
1585
1586The Hurd doesn't support the filetype filesystem feature. The mke2fs
1587program now makes sure that for the Hurd, the filestype feature is
1588turned off. E2fsck will check to see if the filetype feature is
1589turned on for Hurd filesystems, and offer to turn off the feature.
1590
1591Mke2fs now has a safety check to make sure the number of blocks do not
1592exceed 32 bits even on a 64 bit platform.
1593
1594Really fixed a bug in fsck to allow "fsck -As" to run interactive
1595fsck's. (For those people who like to do interactive fsck's in the
1596/etc/rc scripts!?!)
1597
1598Debugfs has a few new features: the rdump command, which will do a
1599recursive dump of a directory and all of its contents, and the lcd
1600command which does a local chdir (much like the ftp command of the
1601same name). In addition, the debugfs program and the open_filesystem
1602command now takes three new options: -b and -s, which allows the
1603blocksize and superblock location to be specified, and the -c option
1604which is used in catastrophic situations where the block group
1605descriptors are corrupt. If the -c option is specified, debugfs will
1606skip trying to read in the block and inode bitmaps.
1607
1608Debufs's lsdel command was fixed to handle bad blocks in the inode
1609table.
1610
1611A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
16124 digit years.
1613
1614General improvements in error messages
1615
1616 - Mke2fs prints a sane error message if the partition size is zero
1617 (usually because the partition table wasn't reread by the
1618 kernel due to the partition being busy), instead of "invalid
1619 argument passed to ext2 library while initializing superblock".
1620
1621 - Fsck now prints more self-explanatory message if an invalid UUID=
1622 or LABEL= specification is passed to it.
1623
1624UUID library changed to use the LGPL.
1625
1626Fixed a bug in the UUID library where very rapid calls to the
1627time-based UUID generator could cause duplicate UUID's to be returned.
1628This was not a problem for e2fsprogs, but it could be a problem for
1629other users of the library.
1630
1631Make the UUID library more robust in the face of missing or an
1632improper /dev/urandom or /dev/random files.
1633
1634Added some random portability fixes for Solaris.
1635
1636Some minor man page updates.
1637
1638Fixed a memory leak in the ss library.
1639
1640
1641Programmer's notes:
1642-------------------
1643
1644We now try to use lseek64 and open64 from the LFS if possible.
1645
1646The 3rd parameter in e2p's print_flags is now a flags word, instead of
1647a boolean option.
1648
1649The mark and unmark bitmap functions now return the previous state of
1650the bit that was being changed, which is useful for some speed
1651optimizations.
1652
1653The following functions have been added to enhance the badblocks list
1654handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1655ext2fs_badblocks_equal.
1656
1657The ext2 header files now have the latest journalling fields to the
1658superblock.
1659
1660The ext2fs_mkdir function in libext2fs now properly backs out of error
1661conditions robustly.
1662
1663Cleaned up makefiles:
1664 - to cleanly compile with the -j flag.
1665 - so distclean removes all generated files.
1666 - so in case of an error while installing header files, the make aborts.
1667
1668Fix test_script so that it works correctly when compiling in the
1669source directory.
1670
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001671The random UUID generation routine has been made slightly better in
1672the case where /dev/random doesn't exist. (Use of randomly-based UUID
1673is still not recommended if /dev/random doesn't exist, however; it's
1674better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00001675
1676Clean up the build process so it's more friendly in case of missing
1677directories.
1678
1679The ext2fs header file can now be #include'd into C++ programs.
1680
1681The e2p.h header file is now installed.
1682
1683Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.

Theodore Ts'o24ded091999-11-10 15:56:16 +00001687E2fsprogs 1.18 (November 10, 1999)
1688==================================
1689
1690Fix a core dumping bug in e2fsck if an imagic inode is present or
1691(more rarely) if the filesystem is badly corrupted enough that e2fsck
1692has to restart pass 1 processing. E2fsck now closes the filesystem
1693before freeing a large number of its data structures, so in the case
1694of future memory faults, at least the fixed filesystem will be fully
1695written out.
1696
1697If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1698imagic inode, it will offer to clear the imagic flag.
1699
1700E2fsck will now offer to clear the immutable flag on special files
1701(device/socket/fifos) when running it in non-preen mode.
1702
1703E2fsck will now set the filetype when creating /lost+found, and when
1704connected orphaned inodes to /lost+found.
1705
1706Debugfs's ncheck and icheck commands now handles the case where there
1707are bad blocks in the inode table without bombing out.
1708
1709The badblocks list processing code has been made more efficiently for
1710appending a large number of (ordered) badblocks to the badblocks list.
1711
1712Some minor man page updates.
1713
1714Fsck now allows interactive e2fsck's when using fsck -As (not a common
1715mode, but some people like to do this in boot scripts for silly reasons).
1716
1717Programmer's notes:
1718-------------------
1719
1720The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1721with the problem code convention.
1722
1723The badblocks list regression test program has been updated to work
1724with previously made API name changes.
1725
1726The ext2fs_free() command now uses the new badblocks API to avoid
1727using the compatibility layer.
1728
1729Added new regression test cases; the run_e2fsck test script now
1730supports the ability for a test case to run a prepratory command
1731before running e2fsck.
1732
Theodore Ts'o28e11941999-10-26 18:17:20 +00001733E2fsprogs 1.17 (October 26, 1999)
1734=================================
1735
1736Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1737infinite loop.
1738
1739Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1740thus potentially causing problems if a binary UUID contained a NULL
1741character.
1742
1743E2fsck now uses stricter checks for directory entries in pass 2:
1744zero-length filenames are not allowed; neither are 8 byte long
1745directory entries.
1746
1747The debugfs "dirty" command now clears the filesystem valid bit.
1748(Previously this just set the dirty-as-in-needs-writing-out-to-disk
1749bit in the in-core superblock image. The new functionality is more
1750what the user expects, and is more useful.)
1751
1752Added a debugging hook to test parallel fsck; if the environment
1753variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1754will be checked in parallel when they normally would not be.
1755
1756Programmer's notes:
1757-------------------
1758
1759Fixed some #ifdef's for compilation under the Hurd OS.
1760
1761Fixed minor W2K compatibility problems.
1762
1763Fixed some miscellaneous GCC warnings.
1764
1765
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001766E2fsprogs 1.16 (October 22, 1999)
1767=================================
1768
1769Fixed a race condition bug in fsck; when printing a progress bar, if
1770checking multiple filesystems in parallel, it was possible for fsck to
1771send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
1772handler, which would cause it to terminate with a signal 10.
1773
1774E2fsck now properly handles filesystems that have the
1775INCOMPAT_FILETYPE feature turned on. It can be used to convert a
1776filesystem into using or not using FILETYPE feature.
1777
1778E2fsck now properly handles filesystems that have the IMAGIC feature
1779turned on (this is used on Linux AFS servers).
1780
1781The mke2fs program now creates filesystems that have the filetype and
1782sparse_superblock features enabled by default, unless it is run on a
1783pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
1784so there is now a new flag -O which allows the user to specify with
1785which features she would like to create the filesystem; "mke2fs -O
1786none" will create a filesystsem compatible with 2.0 kernels.
1787
1788The tune2fs program now has a -O option which allows the user to set
1789and reset "safe" filesystem features. Currently, the only ones which
1790allows to be modified are the filetype and sparse_superblock features.
1791Note setting or clearing either feature will require running e2fsck on
1792the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
1793requires that there is enough free space on the filesystem for the
1794extra superblocks which will be created by e2fsck.)
1795
1796Debugfs can now set and print filesystem features in the superblock
1797using the "features" command. Dumpe2fs will print out the complete
1798set of features when listing the superblock.
1799
1800Dumpe2fs has new options -f (force) and -h (header-only).
1801
1802Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
1803message to come up. This could happen when decrementing or
1804incrementing a link count could result in an overflow.
1805
1806Fixed a bug in e2fsck where the block count on the lost+found
1807directory would not be properly incremented when the directory was
1808expanded to the point where an indirect block needed to be allocated.
1809
1810E2fsck now makes some additional sanity checks on the superblock to
1811avoid crashing or giving a memory allocation error if some of the
1812values in the superblock are unresonable (but the superblock otherwise
1813looks valid).
1814
1815Fixed a bug in e2fsck where a very badly corrupted filesystem might
1816require two passes to completely fix the filesystem. This happened if
1817an inode claimed blocks that was part of the filesystem metadata
1818(typically, when garbage was written into an inode table or indirect
1819block, since this kind of filesystem corruption normally doesn't
1820happen otherwise).
1821
1822On the Alpha, glibc declares st_flags although it isn't actually used;
1823the configure script was improved to detect this case so that
1824e2fsprogs can avoid using the non-functional stat field.
1825
1826The manual pages were updated to use a more consistent formatting
1827style consistent with standard Unix man pages. Mke2fs's man page
1828added documentation for a few previously undocumented options.
1829
1830Fixed minor display bugs in tune2fs and mke2fs.
1831
1832Programmer's notes:
1833-------------------
1834
1835Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
1836
1837Added features to parse and print feature strings into the e2p library.
1838(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
1839
1840ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
1841whose directory entries contain proper filetype information if the
1842filesystem supports it.
1843
1844ext2fs_link() now uses the low 3 bits of its flags parameter to pass
1845the directory entry filetype information. This is used to set the
1846directory entry filetype information if the filesystem supports it.
1847
1848Fixed a bug in ext2fs_expand_dir() where the block count in a
1849directory's inode would not be properly incremented when the directory
1850was expanded to the point where an indirect block needed to be
1851allocated.
1852
1853
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001854E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001855==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001856
1857Add configuration checks so that e2fsprogs will compile cleanly on
1858Linux 2.3 kernels that have renamed i_version to i_generation.
1859
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001860E2fsck now prints a progress/completion bar (and not just a simple
1861spinner) if the -C0 option is requested or if it receives a SIGUSR1
1862signal. Fsck will automatically manage the (potentially muliple)
1863e2fsck processes to print completion bars if it is given a -C option,
1864with the right thing happening if multiple filesystems are being
1865checked in parallel.
1866
1867Mke2fs now has better automatic hueristics to determine the filesystem
1868parameters to be used for a particular filesystem. Added a new option
1869-T which allows the user to specify how the filesystem is to be used,
1870which helps mke2fs do a better job selecting the filesystem parameters.
1871
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001872Mke2fs now creates revision 1 filesystems by default, and with the
1873sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001874not understood by Linux 2.0 kernels, so they will only allow read-only
1875mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001876
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001877Fix bug where if /dev/null couldn't be opened (should never happen),
1878e2fsck would hang in a tight loop.
1879
1880Make e2fsck handle the case where /lost+found isn't a directory.
1881
1882E2fsck now uses mallinfo if it exists to get accurate statistics about
1883its memory usage.
1884
1885Fix bug in e2fsck where it wouldn't check to see if a disconnected
1886inode had any problems before connecting it to /lost+found.
1887
1888Add check to e2fsck so it makes sure that total number of inodes in
1889the filesystem is a sane number.
1890
1891Fix fencepost error when clearing an the end of the block bitmap which
1892caused the last block in the bitmap not to get cleared.
1893
1894Cleaned up a number of messages in e2fsck:
1895 * The message "Group's #'s copy of the group descriptor..."
1896 was fixed so that the correct number would be displayed.
1897 * Added missing space in the "disk write-protected" error messsage
1898 * Cleaned up the error message printed when a non-interactive
1899 e2fsck needs to abort a check because the filesystem
1900 appears to be mounted.
1901
1902Added a new command-line utility, uuidgen, which will create and print
1903a UUID.
1904
1905Make debugfs's icheck command more robust by checking to make sure an
1906inode has valid blocks before interarting over the inode's blocks.
1907
1908UUID generation now uses a random-based scheme whenever possible to
1909prevent potential privacy problems.
1910
1911Man pages for all of the UUID functions in the lirbary were added.
1912
1913Fixed bug in fsck so it won't coredump if a filesystem not in
1914/etc/fstab is given to it.
1915
1916Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
1917that most of the other mount utilities understands.
1918
1919Mke2fs will make a filesystem even if it appears mounted if the force
1920option is given.
1921
1922Dumpe2fs has new command-line options which allow a filesystem expert
1923to specify the superblock and blocksize when opening a filesystem.
1924This is mainly useful when examining the remains of a toasted
1925filesystem.
1926
1927The badblocks program has been updated to display correctly on disks
1928with large block numbers.
1929
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001930The badblocks program no longer gives spurious errors when errors
1931occur on non-block boundaries, which is common if the blocksize is
1932larger than 1k.
1933
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001934Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
1935MKE2FS_SYNC environment variable is set. This is to work around a VM
1936bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001937to trigger it even using a 2.2 kernel, but hopefully it will not be
1938needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001939
1940Fixed miscellaneous documentation and man pages.
1941
1942Programmer's notes:
1943-------------------
1944
1945Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
1946in e2fsck's pass1.c really should have been static.
1947
1948The return value of the uuid_compare() function was changed to make it
1949match with the convetions used by strcmp, memcmp, and Paul Leach's
1950UUID sample document.
1951
1952The "make depend" process has now been made more automated; it now
1953automatically word-wraps the dependencies, and only replaces source
1954Makefile.in if there has been a change in the dependencies. Also, a
1955top-level "make depend" now recurses through all the subdirectories
1956automatically.
1957
1958The Makefile in .../util has been changed so that subst is built using
1959the native C compiler during a cross-compilation, since the subst
1960program is only used during the build process. Also add an explicit
1961rule to build util/subst by cd'ing to the correct directory and
1962running Makefile.
1963
1964The man directories are defined in terms mandir, so that the configure
1965script can override the location of the manual pages.
1966
1967The config files have been updated to recognize new machine types for
1968both the i386 and alpha families.
1969
1970Fsck has been modified so that it will accurately create an
1971fsck_instance even when the noexecute flag is set. This allows for
1972accurate debugging of the fsck pass structure. Also, when the verbose
1973flag is given twice, fsck will print debugging information about when
1974fsck is waiting for jobs to finish.
1975
1976
Theodore Ts'o14790ed1999-01-12 23:32:52 +00001977E2fsprogs 1.14 (January 9, 1999)
1978================================
1979
1980Fix the fstab parsing code so that it can handle blank lines and
1981comment characters. Also, missing pass numbers need to be treated as
1982zero.
1983
1984Fixed a bug in e2fsck where under some circumstances (when e2fsck
1985needs to restart processing after fixing an egregious inconsistency)
1986it would try to access already freed memory.
1987
1988E2fsck now prints non-printable characters in directory entries and
1989pathnames using '^' and 'M-' notation.
1990
1991Fixed chattr so that it will ignore symbolic links when doing
1992recursive descent traversals. For both chattr and lsattr, no longer
1993print the version string unless the -V option is given.
1994
1995Allow the system administrator to directly specify the number of
1996inodes desired in the filesystem, for some special cases where this is
1997necessary.
1998
1999Fix portability problems so that e2fsprogs can be compiled under Linux
20001.2 systems and Solaris systems.
2001
2002Update the config.guess file with a more recent version that will
2003identify newer Linux platforms.
2004
2005Programmer's notes
2006------------------
2007
2008Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2009an inode number of zero is passed to them.
2010
Theodore Ts'o556ad131998-12-19 08:10:58 +00002011E2fsprogs 1.13 (December 15, 1998)
2012==================================
2013
2014Fixed a bug in debugfs where an error messages weren't getting printed
2015when the ext2 library routines to read inodes returned errors in the
2016stat, cmri and rm commands.
2017
2018Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2019provided, it won't create an inode table smaller than the minimum
2020number of inodes required for a proper ext2 filesystem.
2021
2022Fsck now parses the /etc/fstab file directly (instead of using
2023getmntent()), so that it can distinguish between a missing pass number
2024field and pass number field of zero. This caused problems for
2025diskless workstations where all of the filesystems in /etc/fstab have
2026an explicit pass number of zero, and fsck could not distinguish this
2027from a /etc/fstab file with missing pass numbers.
2028
2029E2fsck will create a /lost+found directory if there isn't one in the
2030filesystem, since it's safer to create the lost+found directory before
2031it's needed.
2032
2033Fixed e2fsck so that it would detect bogus immutable inodes which
2034happen to be sockets and FIFO files, and offer to clear them.
2035
2036If a filesystem has multiple reasons why it needs to be checked, and
2037one of the reasons is that it is uncleanly mounted, e2fsck will print
2038that as the reason why the filesystem is being checked.
2039
2040Cleaned up the output routines of mke2fs so that it doesn't overflow
2041an 80 column display when formating really big filesystems.
2042
2043Added a sanity check to e2fsck to make sure that file descriptors 0,
20441, 2 are open before opening the hard disk. This avoids a problem
2045where a broken program might exec e2fsck with those file descriptors
2046closed, which would cause disastrous results if the kernel returns a
2047file descriptor for the block device which is also used by FILE *
2048stdout.
2049
2050Fixed up the e2fsck progress reporting functions so that the values
2051reliably reach 100% at the completion of all of the e2fsck passes.
2052
2053Fixed minor documentation bugs in man pages and usage messages.
2054
2055Programmer's notes:
2056-------------------
2057
2058Fixed a number of lint warnings in the ext2fs library and potential
2059portability problems from other OS's header files that might define
2060CPP macros for names like "max" and "min".
2061
2062ext2fs_badblocks_list_add() has been made more efficient when it needs
2063to grow the bad blocks list.
2064
2065Fixed a bug in e2fsck which caused it to dereference a freed pointer
2066just before exiting.
2067
2068Fixed the substition process for generating the mk_cmds and compile_et
2069scripts so that they will work outside of the build tree.
2070
2071Add sanity check to e2fsck so that if an internal routine
2072(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2073and causing a core dump. This should never happen, but...
2074
Theodore Ts'oa5696711998-07-09 05:38:07 +00002075E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002076==================================
2077
2078E2fsprogs now works with glibc (at least with the version shipped wtih
2079RedHat 5.0). The ext2fs_llseek() function should now work even with
2080i386 ELF shared libraries and if llseek() is not present. We also
2081explicitly do a configure test to see if (a) llseek is in libc, and
2082(b) if llseek is declared in the system header files. (See standard
2083complaints about libc developers don't understand the concept of
2084compatibility with previous versions of libc.)
2085
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002086The ext2fs library now writes out the block group number in each of
2087the superblock copies. This makes it easier to automatically
2088determine the starting block group of the filesystem when the block
2089group information is trashed.
2090
2091Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002092which means that e2fsprogs will ignore the high 8 bits of the
2093directory entry's name_len field, so that it can be used for other
2094purposes.
2095
2096Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2097E2fsprogs will now support filesystems with 64-bit sized files.
2098
2099Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2100
Theodore Ts'o21d53851998-02-21 03:14:50 +00002101Added new program "e2label", contributed by Andries Brouwer. E2label
2102provides an easy-to-use interface to modify the filesystem label.
2103
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002104Fixed bug so that lsattr -v works instead of producing a core dump.
2105
Theodore Ts'o21d53851998-02-21 03:14:50 +00002106Fixed a minor bug in mke2fs so that all groups with bad superblock
2107backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002108
2109Mke2fs will check the size of the device, and if the user specifies a
2110filesystem size larger than the apparent size of the device it will
2111print a warning message and ask if the user wants to proceed.
2112
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002113E2fsck has a new option -C, which sends completion information to the
2114specified file descriptor. For the most part, this is intended for
2115programs to use, although -C 0 will print a spinning character to the
2116stdout device, which may be useful for users who want to see something
2117happening while e2fsck goes about its business.
2118
Theodore Ts'o21d53851998-02-21 03:14:50 +00002119Fixed a bug in e2fsck which could cause a core dump when it needs to
2120expand the /lost+found directory, and sometimes the bitmaps haven't
2121been merged in. Also fixed a related bug where ext2fs_write_dir_block
2122was used to write out a non-directory block. (Which would be bad on a
2123non-Intel platform with byte swapping going on.)
2124
2125Fixed bug in e2fsck where it would print a "programming error" message
2126instead of correctly identifying where a bad block was in used when
2127the bad block was in a non-primary superblock or block group
2128descriptor. Also fixed a related bug when sparse superblocks are in
2129use and there is a bad block where a superblock or block group
2130descriptor would have been in a group that doesn't include a
2131superblock.
2132
2133Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2134the block group descriptor table is corrupt, it was possible to try to
2135allocate a huge array, fail, and then abort e2fsck.
2136ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2137and subsitutes reasonable values if the descriptors are obviously bogus.
2138
2139If e2fsck finds a device file which has the immutable flag set and the
2140i_blocks beyond the normal device number are non-zero, e2fsck will
2141offer to remove it, since it's probably caused by garbage in the inode
2142table.
2143
2144When opening a filesystem, e2fsck specially checks for the EROFS error
2145code, and prints a specific error message to the user which is more
2146user friendly.
2147
2148If the filesystem revision is too high, change the e2fsck to print
2149that this is either because e2fsck is out of date, or because the
2150superblock is corrupt.
2151
2152E2fsck now checks for directories that have duplicate '.' and '..'
2153entries, and fixes this corruption.
2154
2155E2fsck no longer forces a sync of the filesystem (with attendant sleep
2156calls) at all times. The ext2fs_flush() function now performs a sync
2157only if it needed to write data blocks to disk.
2158
2159Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2160certain errors would not be properly reported.
2161
2162Updated and expanded a few points in the man pages which users
2163complained wheren't explicit enough.
2164
2165Added special case byte-swapping code if compiling on the PowerPC, to
2166accomodate the strange big-endian variant of the ext2 filesystem that
2167was previously used on the PowerPC port.
2168
2169
2170Programmer's notes:
2171-------------------
2172
2173Removed C++ keywords from the ext2fs libraries so that it could be
2174compiled with C++.
2175
2176E2fsck's internal organization has now been massively reorganized so
2177that pass*.c don't have any printf statements. Instead, all problems
2178are reported through the fix_problem() abstraction interface. E2fsck
2179has also been revamped so that it can be called as a library from a
2180application.
2181
2182Added new fileio primitives in libext2fs for reading and writing
2183files on an unmounted ext2 filesystem. This interface is now used by
2184debugfs.
2185
2186Added a new libext2fs function for mapping logical block numbers of
2187a file to a physical block number.
2188
2189Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2190a block, zeros it, and updates the filesystem accounting records
2191appropriately.
2192
2193Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2194sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2195
2196The libext2fs functions now use a set of memory allocation wrapper
2197functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2198instead of malloc, free, and resize. This makes it easier for us to
2199be ported to strange environments where malloc, et. al. aren't
2200necessarily available.
2201
2202Change the libext2fs fucntion to return ext2-specific error codes
2203(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2204and depending on the existence of system error codes (such as EEXIST
2205and ENOENT).
2206
2207Renamed io.h to ext2_io.h to avoid collision with other OS's header
2208files.
2209
2210Add protection against ext2_io.h and ext2fs.h being included multiple
2211times.
2212
2213The types used for memory lengths, etc. have been made more portable.
2214In generla, the code has been made 16-bit safe. Added Mark
2215Habersack's contributed DOS disk i/o routines.
2216
2217Miscellaneous portability fixes, including not depending on char's
2218being signed.
2219
2220The io_channel structure has a new element, app_data, which is
2221initialized by the ext2fs routines to contain a copy of the filesystem
2222handle.
2223
2224ext2fs_check_directory()'s callback function may now return the error
2225EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2226really do the checking, despite the presence of the callback function.
2227
2228
Theodore Ts'obc210071997-06-17 05:41:36 +00002229E2fsprosg 1.11 (June 17, 1997)
2230==============================
2231
2232Fixed e2fsck to detect (previously ignored) conflicts between the
2233superblock or block group descriptors and block bitmaps, inode
2234bitmaps, and inode tables.
2235
2236Fixed bug in e2fsck so that when the message printed out when a block
2237or inode bitmap conflicts with other data, it has the correct group
2238number.
2239
2240Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2241to badblocks. This meant that not all of the filesystem was being
2242tested for bad blocks!
2243
2244Fixed an array boundary overrun case which cropped up in
2245ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2246-b 4096".
2247
2248Adjusted the number of columns printed by mke2fs when displaying the
2249superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00002250really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00002251
2252Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2253dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2254fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2255
2256Programmer's notes:
2257-------------------
2258
2259Fixed install rule in lib/ss so that ss_err.h is actually getting
2260installed.
2261
2262Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2263bassed back to the caller.
2264
2265Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2266setting the current inode number (which meant this function wasn't
2267working at all).
2268
2269Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2270blocks in the bitmap when increasing the size of the bitmap.
2271
2272Changed the initial number of blocks allocated by ext2fs_init_dblist()
2273to be more realistic.
2274
2275Added a new function ext2fs_allocate_group_table, which sets up the
2276group descriptor information (and allocates inode and block bitmaps,
2277and inode tables for a particular group). The function was created by
2278factoring out code form ext2fs_allocate_tables().
2279
2280Added a new function ext2fs_move_blocks which takes a bitmap of the
2281blocks to be moved, and moves them to another location on the
2282boardboard.
2283
2284Make the unix_io channel's io_channel_flush implementation calls sync()
2285to to flush the kernel buffers to disk.
2286
2287Added a new function ext2fs_dblist_count returns the number of
2288directory blocks in dblist.
2289
2290
Theodore Ts'oae851481997-04-29 18:13:24 +00002291E2fsprogs 1.10 (April 24, 1997)
2292===============================
2293
2294Mke2fs once again defaults to creating revision #0 filesystems, since
2295people were complaining about breaking compatibility with 1.2 kernels.
2296Warning messages were added to the mke2fs and tune2fs man pages that
2297the sparse superblock option isn't supported by most kernels yet (1.2
2298and 2.0 both don't support parse superblocks.)
2299
2300Added new flag to mke2fs, -R <raid options>, which allows the user to
2301tell mke2fs about the RAID configuration of the filesystem. Currently
2302the only supported raid option is "stride" which specifies the width
2303of the RAID stripe.
2304
2305Fixed bug in e2fsck where pass1b would bomb out if there were any
2306blocks marked bad in the inode table.
2307
2308Fixed rare bug in mke2fs where if the user had a very unlucky number
2309of blocks in a filesystem (probability less than .002) the resulting
2310filesystem would be corrupt in the last block group.
2311
2312Fixed bug where if e2fsck tried to allocate a block to fix a
2313filesystem corruption problem and the filesystem had no free blocks,
2314ext2fs_new_block() would loop forever.
2315
2316The configure script now checks explicitly to see if "-static" works,
2317since that can't be assumed to be true --- RedHat doesn't install
2318libc-static by default.
2319
2320Fixed bug in libext2's block iterator functions where under some
2321cirmcustances, file with holes would cause the bcount parameter to the
2322callback function to be incorrect. This bug didn't affect any of
2323e2fsprogs programs, but it was discovered by Paul Mackerras, the
2324author of the PPC boot loader.
2325
2326Removed use of static variables to store the inode cache in libext2fs.
2327This caused problems if more than one filesystem was accessed via
2328libext2fs (static variables in libraries are generally a bad idea).
2329Again, this didn't affect e2fsprogs programs, but it was discovered by
2330Paul Mackerras.
2331
2332Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
2333will compile cleanly with 1.2.13 kernels (even with a.out shared
2334libraries!)
2335
2336Programmer's notes:
2337-------------------
2338
2339Added new functions to duplicate an ext2 filesystem handle, and its
2340associated substructure. New functions: ext2fs_dup_handle(),
2341ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
2342Other structures, such as the io_channel and the inode_cache, now have
2343a ref count so that they only get freed when they are no longer used
2344by any filesystem handle. (These functions were added as part of the
2345development effort for an ext2 resizer).
2346
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00002347E2fsprogs 1.09 (April 14, 1997)
2348===============================
2349
2350Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
2351accidentally introduced in the 1.08 release. The overhead calculation
2352was accidentally removed, which caused ext2fs_initialize() to not
2353notice when the filesystem size needed to be adjusted down because
2354there wasn't enough space in the last block group.
2355
2356Fixed bug in version parsing library routine; it was always parsing
2357the library version string, instead of using the passed-in string.
2358
2359Clarified chattr man page.
2360
Theodore Ts'o24757fa1997-04-29 17:39:27 +00002361E2fsprogs 1.08 (April 10, 1997)
2362===============================
2363
2364E2fsck 1.07 was very slow when checking very large filesystems with a
2365lot of files that had hard links (i.e., news spools). This was fixed
2366by seriously revamping the icount abstraction. Added a formal test
2367suite for the icount abstraction.
2368
2369Debugfs now has a "-l" option to the "ls" command, which lists the
2370inode number, permissions, owner, group, size, and name of the files
2371in the directory.
2372
2373Fix a bug in e2fsck where when a directory had its blocks moved to
2374another location during the pass 1b processing, the directory block
2375list wasn't updated, so pass 2 wouldn't check (and correct) the
2376correct directory block.
2377
2378E2fsck will now treat inodes which contain blocks which are claimed by
2379the filesystem metadata by treating them as multiply claimed blocks.
2380This way, the data in those blocks can be copied to a new block during
2381the pass 1b--1d processing.
2382
2383E2fsck will attempt to determine the correct superblock number and
2384display it in the diagnostic and warning messages if possible.
2385
2386Add support for a new (incompatible) feature, "sparse_super". This
2387feature reduces the number of blocks which contain copies of backup
2388superblocks and block group descriptors. (It is only an incompatible
2389feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
2390support a new -s option; e2fsck will recognize filesystems built with
2391this feature turned on.
2392
2393E2fsck now checks the library to make sure is the correct version,
2394using new library functions. (This helps to diagnose incorrectly
2395installed e2fsprogs distributions.)
2396
2397Dumpe2fs now prints more information; its now prints the the
2398filesystem revision number, the filesystem sparse_super feature (if
2399present), the block ranges for each block group, and the offset from
2400the beginning of the block group.
2401
2402Mke2fs now distributes the inode and block bitmap blok so that the
2403won't be concentrated in one or two disks in RAID/striping setups.
2404Also, if the user chooses a 2k or 4k block group, mke2fs will try to
2405choose the largest blocks per group that be chosen. (For 2k blocks,
2406you can have up to 16384 blocks/group; for 4k blocks, you can have up
2407to 32768 blocks/group.) Previously mke2fs would not allow
2408specification of more than 8192 blocks per group, even if you were
2409using a 2k or 4k block group.
2410
2411Programmer's notes:
2412-------------------
2413
2414Added a new function ext2fs_create_icount2() which takes a "hint"
2415argument. This hint argument presets the icount array with the list
2416of inodes which actually need to be in the icount array. This really
2417helps to speed up e2fsck.
2418
2419Added a new function ext2fs_icount_validate() which checks the rep
2420invariant for the icount structure. This is used mostly for testing.
2421
2422The error mesasage given when a bad inode number is passed to
2423test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
2424EXT2FS_UNMARK_ERROR).
2425
2426Added a new function ext2fs_set_dir_block which sets the block of a
2427dblist entry, given the directory inode and blockcnt.
2428
2429Added a new function ext2fs_get_library_version() which returns the
2430current library version, and ext2fs_parse_version_string() which
2431returns a version number based on a e2fsprogs version string.
2432
2433The icount functions will return EINVAL if the passed in inode number
2434is out of bounds.
2435
Theodore Ts'o21c84b71997-04-29 16:15:03 +00002436E2fsprogs 1.07 (March 9, 1997)
2437==============================
2438
2439E2fsck is now uses much less memory when checking really large
2440filesystems (or rather, filesystems with a large number of inodes).
2441Previously a filesystem with 1 million inodes required 4 megabytes of
2442memory to store inode count statistics; that storage requirement has
2443now been reduced to roughly half a megabyte.
2444
2445E2fsck can now properly deal with bad blocks appearing inside the
2446inode table. Instead of trying to relocate the inode table (which
2447often failed because there wasn't enough space), the inodes in the bad
2448block are marked as in use.
2449
2450E2fsck will automatically try to use the backup superblocks if the
2451primary superblocks have a bad magic number or have missing meta-data
2452blocks (or meta-data blocks which are out of range).
2453
2454E2fsck's pass 3 has been made more efficient; most noticeable on
2455filesystems with a very large number of directories.
2456
2457Completely revamped e2fsck's system of printing problem reports. It
2458is now table driven, to make them more easily customizeable and
2459extendable. Error messages which can be printed out during preen mode
2460are now one line long.
2461
2462Fixed e2fsck's filesystem swapping code so that it won't try to swap
2463fast symbolic links or deleted files.
2464
2465Fixed e2fsck core dumping when fixing a filesystem which has no
2466directories (not even a root directory).
2467
2468Added a check to e2fsck to make sure that the length of every
2469directory entry is a multiple of 4 (since the kernel complains if it
2470isn't).
2471
2472Added a check to e2fsck to make sure that a directory entry isn't a
2473link to the root directory, since that isn't allowed.
2474
2475Added a check to e2fsk to now make sure the '.' and '..' directory
2476entries are null terminated, since the 2.0 kernel requires it.
2477
2478Added check to write_bitmaps() to make sure the superblock doesn't get
2479trashed if the inode or block bitmap is marked as being block zero.
2480
2481Added checking of the new feature set fields in the superblock, to
2482avoid dealing with new filesystem features that this package wasn't
2483set up to handle.
2484
2485Fixed a fencepost error in ext2fs_new_block() which would occasionally
2486try to allocate a block beyond the end of a filesystem.
2487
2488When the UUID library picks a random IEEE 802 address (because it
2489can't find one from a network card), it sets the multicast bit, to
2490avoid conflicting with a legitimate IEEE 802 address.
2491
2492Mke2fs now sets the root directory's owner to be the real uid of the
2493user running mke2fs. If the real uid is non-zero, it also sets
2494the group ownership of the root directory to be the real group-id of
2495the user running mke2fs.
2496
2497Mke2fs now has more intelligent error checking when it is given a
2498non-existent device.
2499
2500When badblocks is given the -vv option, it now updates the block that
2501it is currently testing on every block.
2502
2503Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
2504currently correctly if PATH wasn't already set.
2505
2506Shared libraries now built with dependencies. This allows the shared
2507library files to be used with dlopen(); it also makes the transition
2508to libc 6 easier, since ld.so can tell which libc a particular shared
2509library expects to use.
2510
2511Programmer's notes:
2512-------------------
2513
2514Added new abstraction (defined in dblist.c) for maintaining a list of
2515blocks which belongs to directories. This is used in e2fsck and other
2516programs which need to iterate over all directories.
2517
2518Added new functions which test to see if a contiguous range of blocks
2519(or inodes) are available. (ext2fs_*_bitmap_range).
2520
2521Added new function (ext2_inode_has_valid_blocks) which returns true if
2522an inode has valid blocks. (moved from e2fsck code).
2523
2524Added new function (ext2fs_allocate_tables) which allocates the
2525meta-data blocks as part of initializing a filesystem. (moved from
2526mke2fs code).
2527
2528Added a new I/O manager for testing purposes. It will either allow a
2529program to intercept I/O requests, or print debugging messages to
2530trace the activity of a program using the I/O manager.
2531
2532The badblocks_list functions now store the bad blocks in a sorted
2533order, and use a binary search to speed up badblocks_list_test.
2534
2535The inode scan function ext2fs_get_next_inode() may now return a soft
2536error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
2537those cases where part of an inode table is missing or there is a bad
2538block in the inode table.
2539
2540Added a new function (ext2fs_block_iterate2) which adds new arguments to
2541the callback function to return a pointer (block and offset) to the
2542reference of the block.
2543
2544Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
2545application to jump to a particular block group while doing an inode
2546scan.
2547
2548The badblocks list functions were renamed from badblocks_* to
2549ext2fs_badblocks_*. Backwards compatibility functions are available
2550for now, but programs should be modified to use the new interface.
2551
2552Some of the library functions were reorganized into separate files to
2553reduce the size of some programs which statically link against the
2554ext2 library.
2555
2556Put in some miscellaneous fixes for the Alpha platform.
2557
Theodore Ts'o5c576471997-04-29 15:29:49 +00002558
2559E2fsprogs 1.06 (October 7, 1996)
2560================================
2561
2562Fixed serious bug in e2fsck: if the block descriptors are bad, don't
2563smash the backup copies in ext2fs_close(). (The problem was that when
2564e2fsck -p discovered the problem, while it was closing the filesystem
2565and exiting, it was also blowing away the backup superblocks on the
2566disk, which was less than friendly.) We now make it the case that we
2567only write out the backup superblock and the back block descriptors if
2568the filesystem is completely free from problems.
2569
2570Fixed a bug in block_interate in the lib/ext2fs library which caused
2571e2fsck to fail on GNU Hurd-created filesystems.
2572
2573Add support for Linux/FT's bootloader, which actually uses
2574EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
2575to clear the inode.
2576
2577Add support for the "A" (no atime update) attribute. (Note: this
2578attribute is not yet in production kernels.)
2579
2580The test suite is not automatically run when doing a "make all" from
2581the top level directory. Users should manually run "make check" if
2582they wish to run the test suite.
2583
2584Upon a preenhalt(), make the printed message more explicit that
2585running e2fsck "MANAULLY" means without the -p or -a options.
2586
2587In e2fsck, if a disconnected inode is zero-length, offer to clear it
2588instead of offering to connect it to lost+found.
2589
2590In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2591e2fsck to be run over it, change e2fsck to explicitly display this
2592fact.
2593
2594For dumpe2fs and e2fsck, cause the -V option to print out which
2595version of the ext2fs library is actually getting used. (This will
2596help detect mismatches of using a 1.06 utility with a 1.05 library,
2597etc.)
2598
2599Programmers' notes:
2600-------------------
2601
2602EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2603the naming convention.
2604
2605In ext2fs_initialize(), make sure the description for the inode bitmap
2606is correctly initialize.
2607
2608Fixed minor type typo in ext2fs_allocate_generic_bitmap();

Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002610E2fsprogs 1.05 (September 7, 1996)
2611==================================
2612
2613Add support for new fields in the ext2 superblock --- volume name,
2614volume UUID, and last mounted field. Dumpe2fs displays these fields,
2615tune2fs and mke2fs allows you to set them. E2fsck will automatically
2616generate a UUID for those volumes that don't have them.
2617
2618Put in support for e2fsck to recognize HURD specific ext2 features ---
2619most notably, the translator block. The e2fsprogs tools will now use
2620the creator_os field in the superblock to correctly handle different
2621OS-specific variants of the ext2 filesystem.
2622
2623E2fsck now fixes inodes which have a the deletion time set, but which
2624have a non-zero i_link_count field by offering to clear the deletion
2625time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2626ext2 kernel behavior) and offered to unlink the file.
2627
2628If e2fsck sets the clean bit, but nothing else, set the exit code
2629FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2630set the filesystem valid bit when it was previously cleared. :-) This
2631was needed to make the HURD fsck driver happy.
2632
2633If the user refuses to attach an unattached inode, e2fsck will no
2634longer set the inode's link count. Otherwise, the inode would end up
2635getting marked as unused, which might cause loss of data later.
2636
2637Make the message issued by e2fsck when the superblock is corrupt less
2638confusing for users. It now mentions that another reason for the
2639"corrupt superblock" message might be that the partition might not be
2640an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2641
2642Make the libext2 library more robuest so that e2fsck won't coredump on
2643an illegal superblock where the blocksize is zero. (f_crashdisk is
2644the test case).
2645
2646By default, create filesystems where the default checkinterval is 6
2647months (180 days). Linux servers can be robust enough that 20 reboots
2648can be a long, long time.
2649
2650Added configure flag --enable-old-bitops, which forces the bitops to
2651use the old (native) bitmask operations. By default on the sparc
2652platform, the standard ext2 bit ordering is now used.
2653
2654Added a new feature to e2fsck to byte-swap filesystems; this can be
2655used to convert old m68k filesystems to use the standard byte-order
2656storage for the superblock, inodes, and directory blocks. This
2657function is invoked by using the '-s' option to e2fsck.
2658
2659Debugfs's "dump" command has been enhanced so that it writes out the
2660exact size of the file so that the nulls at the end of the file are
2661eliminated. The command also accept a new "-p" option which will
2662attempt preserve to preserve the ownernship, permissions, and
2663file modification/access times.
2664
2665Debugfs has two new options, -f and -R. The -R option allows the user
2666to execute a single debugfs command from the command line. The -f
2667option allows the user to specify a "command file" containing debugfs
2668commands which will get executed.
2669
2670Dumpe2fs now pretty prints the check interval, instead of just
2671printing the check interval as a number of seconds.
2672
2673Fix bugs in debugfs: the params command when no filesystem is opened
2674no longer causes a core dump. It is now possible to unlink a file
2675when a pathame containing a '/' is specified.
2676
2677Tune2fs has a new -C option which sets the number of times the
2678filesystem has been mounted.
2679
2680Fix the chattr '-v' option so that it actually works. Chattr was
2681being buggy about the -v option parsing.
2682
2683Programmers' notes:
2684-------------------
2685
2686The directory lib/uuid contains a set of library routines to generate
2687DCE compatible UUIDs.
2688
2689Extended ext2fs_namei() to handle symbolic links. Added new function
2690ext2fs_nami_follow() which will follow last symbolic link in the case
2691where the pathname points to a sym link.
2692
2693The ext2fs_block_iterate function will now return the HURD translator
2694block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2695iterator to return data blocks only. The ext2fs.h file now defines
2696constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2697BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2698count field of the iterator callback function.
2699
2700The test script driver now takes an optional second argument, which is
2701the test case to be run. This allows you to run a test case without
2702needing to run the entire test suite.
2703
2704On Linux ELF systems, install the .so files in the correct places
2705(/usr/lib). The .so files must be stored in the same directory as the
2706.a files.
2707
2708Fixed miscellaneous HURD compilation issues with header file being
2709included in the right order.
2710
2711Fixed debugfs so that it resets optind to zero, not one, since setting
2712optind to zero is more correct.

Theodore Ts'oa4d09611997-04-29 14:28:00 +00002715E2fsprogs 1.04 (May 16, 1996)
2716=============================
2717
2718First "official" (1.03 was a limited release only) to support building
2719e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2720kernels).
2721
2722This package includes a RPM specs file, that it can be built using the
2723RedHat Package Manager.
2724
2725E2fsck now prints a hint that if there are lots of incorrectly located
2726inode bitmaps, block bitmaps, and inode table blocks, the user might
2727want to try using e2fsck -b 8193 first, to see if that fares any
2728better.
2729
2730For ext2 filesystem written with the hurd, debugfs will now print out
2731the translator field when printing an inode structure.
2732
2733Lots of miscellaneous linking/installation cleanups:
2734
2735 Libraries are now linked using a relative pathname, instead of
2736 relying on -L working correct. It doesn't, in many cases, including
2737 current versions of GNU ld. This guarantees that the build tree is
2738 linking with the right libraries, instead of the ones installed in
2739 /usr/lib.
2740
2741 Header files, man pages, and the et/ss shell scripts are now
2742 generated using a custom substitution script, instead of relying on
2743 the configure script. This prevents needless recompilation of
2744 files; in addition, the custom substitution script is much faster.
2745
2746 e2fsck may now be linked dynamically, by using the
2747 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2748 since it increases e2fsck's dependence on other files, but some
2749 people need to save disk space, and other critical programs on their
2750 systems were being linked dynamically anyway.
2751
2752 Programs such as fsck which didn't need to be linked against
2753 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2754 only link against libraries they actually need. Otherwise, those
2755 programs would require the presense of libraries that otherwise
2756 could be removed from a rescuse diskette.
2757
2758 The ss include files are now installed correctly so they can
2759 actually be used by another package.
2760
2761 If the profiling libraries are built, they are now installed on a
2762 "make install-libs".

Theodore Ts'o7f88b041997-04-26 14:48:50 +00002765E2fsprogs 1.03 (March 27, 1996)
2766===============================
2767
2768Change the m68k bit numbering for bitmasks to match the bit numbering
2769used by all other ext2 implementations. (This change was requested by
2770the m68k kernel development team.)
2771
2772Support (in-development) filesystem format revision which supports
2773(among other things) dynamically sized inodes.
2774
2775Fixed a bug in the ext2 library so that an intelligent error is
2776returned if mke2fs is run with a ridiculously small number of blocks
2777for a partition.
2778
2779Fixed a bug in the ext2 library which required that the device be
2780openable in read/write mode in order to determine its size. This
2781caused e2fsck -n to require read/write access when it was not
2782previously necessary.
2783
2784Fixed a bug in e2fsck which casued it to occasionally fail the test
2785suite depending on which version of the floating point library it was
2786using.
2787
2788Fixed a bug in e2fsck so that it now halts with a fatal error when
2789certain superblock consistency checks fail. Previously it continued
2790running e2fsck, with some potential confusing/damaging consequences.
2791
2792Added new flag to fsck which allows the root to be checked in parallel
2793with other filesytems. This is not the safest thing in the world to
2794do, but some system administrators really wanted it.
2795
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002796Fixed -Wall flames in lib/ss.
2797
Theodore Ts'o74becf31997-04-26 14:37:06 +00002798
2799E2fsprogs 1.02 (January 16, 1996)
2800=================================
2801
2802Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
2803
2804Change e2fsck to print statistics of how many non-contiguous files are
2805on the system. Note that a file which is larger than 8k blocks, it is
2806guaranteed to be non-contiguous.
2807
2808In mke2fs, print a warning message if a user tries to format a whole
2809disk (/dev/hda versus /dev/hda1). If a user really wants to format a
2810whole disk, the -F (force) option forces mke2fs to format a whole disk
2811as a filesytem.
2812
2813Fix a bug in fsck where in some cases it might start checking
2814partitions in the next pass before it finishes checking partitions in
2815the current pass. This still won't cause two partitions on the same
2816disk will be checked, so it's rarely a problem in real life.
2817
2818Patch lsattr so that it won't hang when checking a named pipe.
2819
2820Minor compilation fixes:
2821 * Fix the order of libraries that were linked in debugfs.
2822 * Allow the sources to be compiled with -ansi turned on.
