Theodore Ts'ob70b1162004-02-28 10:52:35 -05001E2fsprogs 1.35 (February 28, 2004)
2==================================
3
4E2fsck has a new -k option, which in conjuction with the -c options,
5preserves the existing badblocks list.
6
7Cleaned up e2fsck's preem-mode messages during the passes 1b, 1c, and 1d.
8
9E2fsprogs will now deal correctly with symlinks that contain
10extended attribute information, which can be created using SE Linux.
11(Addresses Debian Bug #232328)
12
13Remove a double longjump into an invalid stack frame bug in e2fsck.
14(This was during an abort sequence, which normally worked on Linux and
15caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050016
Theodore Ts'o1daf7582004-01-31 22:33:16 -050017Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
18(the NLS library will replace "" with the .po header information).
19
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050020Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
21dump due to a division by zero error. (Addresses Debian bug #207082)
22
Theodore Ts'o151a7162003-12-26 14:04:33 -050023Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
24when reconnecting a directory requires creating a lost+found
25directory. (Addresses Debian bug #219640).
26
27Fixed a bug where e2fsck would bomb out if a journal needed to be
28replayed when using an alternate superblock.
29
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500302fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050031if the laptop is running on battery. The next time fsck runs while
32the system is on the AC mains, or after the grace period is exceeded,
33the filesystem will be checked. (Addresses Debian bug #205177)
34
35E2fsck will inform the user when there are 5 or fewer mounts before a
36filesystem check will be forced. (Addresses Debian bug #157194)
37
38Fix e2fsck's handling of corrupted indirect blocks in the bad block.
39We now correctly handle the case where there is an overlap between a
40block group descriptor or a superblock and a bad block indirect block.
41In the case where the indirect block is corrupted, we now suggest
42"e2fsck -c".
43
Theodore Ts'o1daf7582004-01-31 22:33:16 -050044Fix byte swap bugs in e2fsck that caused the journal backup location
45in the superblock and symlinks created by SE Linux to be cleared
46by e2fsck on big-endian machines. (Addresses Debian bug #228723)
47
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050048E2fsck -c now replaces the current list of bad blocks with the ones
49found by badblocks.
50
51Fix bugs in e2fsck and tune2fs which could cause a core dump if a
52non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
53
54Fix a potential bug in e2fsck which could cause it to core dump when
55trying to print the location of the backup superblock.
56
57Protect against a potential core dump in e2fsck when printing a
58message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -040059
Theodore Ts'o6826bde2003-08-21 02:14:44 -040060Add support for backing up the journal inode location in the
61superblock. E2fsck will automatically save the journal information in
62the superblock if it is not there already, and will use it if the
63journal inode appears to be corrupted. ext2fs_add_journal_inode()
64will also save the backup information, so that new filesystems created
65by mke2fs and filesystems that have journals added via tune2fs will
66also have journal location written to the superblock as well.
67Debugfs's logdump command has been enhanced so that it can use the
68journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -050069
70E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -040071
72Shrink the size of the e2fsck executable by moving some initialized
73variables to the BSS segment.
74
75E2fsck will avoid printing the ^A and ^B characters which bracket the
76progress bar when stdout and stdin are a tty device instead of a pipe
77to another program. (Addresses Debian bug #204137)
78
Theodore Ts'o151a7162003-12-26 14:04:33 -050079Debugfs's mkdir command will automatically expand the directory if
80necessary. (Addresses Debian Bug: #217892)
81
82Fixed a bug in debugfs so that copying a file from /dev/null uses the
83correct mode bits. (Addresses Debian Bug: #217456)
84
85If the environment variables DEBUFS_PAGER and PAGER are not set,
86debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -050087/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -050088(Addresses Debian bug #221977)
89
Theodore Ts'ob70b1162004-02-28 10:52:35 -050090Debugfs will now support 2.6 device numbers where the major or minor
91number may be larger than 255. (Addresses Sourceforge bug #865289)
92
Theodore Ts'o1daf7582004-01-31 22:33:16 -050093Chattr now stops processing options when it sees '--'. (Addresses
94Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -050095
Theodore Ts'o858dd7b2003-08-02 20:48:35 -040096Fix regression tests so they work correctly when e2fsprogs is compiled
97with configure --disable-htree.
98
Theodore Ts'o1daf7582004-01-31 22:33:16 -050099Fix bug in uuid library when there is no network card and the library
100is generating a time-based uuid. The random MAC address was not
101correctly generated to be a multicast address.
102
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400103Add compile_et extensions from Heimdall that were missed the first time
104arounded.
105
106Fix bug in badblocks when using O_DIRECT; we need to make sure that
107we're reading from an offset which is page aligned. For read-only and
108read-write tests, we try to recover after an error so that we can
109continue reading on page-aligned boundaries. (Addresses Debian Bug
110#203713)
111
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500112Badblocks now checks 64 blocks at a time instead of 16. (Addresses
113Debian bug #232240)
114
Theodore Ts'o151a7162003-12-26 14:04:33 -0500115Updated and clarified various man pages. (Addresses Debian Bug
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500116#206845, #222606, #214920, #232406)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500117
Theodore Ts'o151a7162003-12-26 14:04:33 -0500118Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400119
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400120Fixed various Debian packaging issues (see debian/changelog).
121
122Programmer's notes:
123-------------------
124
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500125Fixed a build problem so that e2fsprogs would compile with the
126--enable-profile option to configure selected. (Addresses Sourceforge
127bug #811408)
128
129Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
130Bugzilla Bug #112448)
131
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500132Centralize code which calculates the location of the superblock
133and block group descriptors so that it is in a single library routine.
134
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400135Added two new functions, ext2fs_file_open2() and
136ext2fs_inode_io_intern2() which take a pointer to an inode structure.
137
138Fix compile_et to output the correct prototype for
139initialize_xxx_err_table_r() in the header file. (Addresses Debian
140bug #204332)
141
142In the lib/et makefile, make sure com_err.info is deleted on "make clean".
143
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400144Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
145present. This is for when we try stuffing an int into void * pointer.
146
147Fix type-punning which can cause gcc 3.x to miscompile code by getting
148confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
149and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
150**'. The EVMS code uses an ugly union approach since we don't want to
151modify the EVMS interfaces.
152
153Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
154aid build process on systems can use invoke GNU make as "gmake".
155
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500156Added regression testing for mke2fs.
157
158Fixed gcc -Wall nitpicks.
159
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500160Fixed various compiler warnings.
161
162Add portability fixes for FreeBSD and for using fsctl under Darwin to
163support ext2 ioctl's.
164
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400165
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400166E2fsprogs 1.34 (July 25, 2003)
167===============================
168
169Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
170a tight loop while waiting for a child fsck to exit in some cases.
171This burns CPU times which slows down the low-level filesystem check.
172
173Added code to mke2fs to assure that the default block size for a
174filesystem is at least as big as the sector size of the device, if it
175can be determined.
176
177Changed mke2fs and resize2fs to round the default size of a filesystem
178to be an even multiple of the VM pagesize in order to avoid a Linux
179kernel bug introduced when the storage of the buffer cache was moved
180into the page cache.
181
182Mke2fs will warn the user when creating a filesystem with journaling
183and a blocksize greater than 4096. (Addresses Debian bug #193773)
184
185Fixed a bug in resize2fs which caused it to fail on filesystems with a
186non-empty bad block list. Resize2fs now discards any blocks on the
187badblock list which are no longer part of the filesystem as the result
188of a filesystem shrink. (Note: this means that shrinking and then
189enlarging a filesystem is no longer a reversible operation;
190information about bad blocks in the part of the filesystem which is to
191be chopped off will be lost.)
192
193Changed resize2fs so the user can use prefixes to specify the units of
194the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
195and to make the error and informational messages explicitly display
196the blocksize used by the filesystem, in order to avoid confusion.
197(Addresses Debian bug: #189814)
198
199Added a new debugfs command, dump_unused, which dumps the contents of
200all unused blocks to stdout. (Useful as an emergency try-to-find
201deleted data command.)
202
203Added a new debugfs command, imap, which prints the location of a
204specified inode in the inode table.
205
206Fixed a bug in the badblocks program which caused it to use one bit of
207randomness in its non-destructive read/write test, instead of using a
208full 8 bits of randomness.
209
210Added a new option (-t) to badblocks, which allows the user to control
211the test pattern(s) used when checking a disk.
212
213The blkid probe function now more correctly detects UDF filesystems.
214
215Fixed a bug in the blkid library which caused it to not update its
216cache if a filesystem changes from having a label to not having a
217label.
218
219Fixed a bug in the blkid library wihch could avoid an infinite loop
220in blkid_find_dev_with_tag() if /proc is not mounted and there the
221/etc/blkid.tab file has not yet been created.
222
223Fixed the badblocks program so that the destructive read/write test
224honors the -c option, and to use O_DIRECT when possible to avoid
225thrashing the system block buffer cache.
226
227Fixed various NLS issues.
228 - Added Czech and Sweedish translations
229 - Removed testing NYC translation
230 - Fixed NLS support for message abbrevations in e2fsck
231 - Remove de-utf.po, since we shouldn't have two versions using different
232 charset encodings.
233 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
234 simplify the statistics reporting in e2fsck.
235
236Changed configure.in so that its defaults for *BSD systems no longer
237build an fsck wrapper, and not to install in /usr/local by default.
238
239Fixed some minor spelling errors/typo's in e2fsck and the configure
240script.
241
242Fixed various Debian packaging issues (see debian/changelog).
243
244Updated and clarified man pages. (Addresses Debian Bug #195616)
245
246Programmer's notes:
247-------------------
248
249Fix gcc -Wall nitpicks.
250
251Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
252NLS support by default. (Added partial workaround for gettext/Darwin
253incompatibility problems.)
254
255Added full MIT KRB5 and Himdall compaibility support to the com_err
256library and the compile_et program. (Addresses Debian bug #191900)
257
258Added the blkid_known_fstype() function to the blkid library, which
259returns true if it is passed a filesystem type which is recognized by
260the blkid probing functions.
261
262Improved the documentation for the blkid library.
263
264Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
265returns the hardware sector size of a device, if it is available.
266
267Added a dependency in the blkid library's .so file to the uuid
268library, since the former uses the latter. (Addresses Debian bug
269#194094)
270
271Added --with-diet-libc and --disable-evms to the configure script.
272
273Fixed a minor memory leak in the badblocks program.
274
275Fixed a portability problem in tune2fs --- not all systems have strptime().
276
277Fixed a portability problem in debugfs with the use of getopt() more
278than once. Old-style BSD, new-style BSD, and Linux C libraries all do
279things differently.
280
281Add support Windows support to ext2fs_get_device_size().
282
283Added (normally disabled) debugging code to the Unix I/O manager which
284causes it to disable all userspace caching if the NO_IO_CACHE is
285defined.
286
287Changed the test I/O manager so it can always be linked into e2fsck,
288mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
289configure script. The test I/O manager will only print any debugging
290information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
291variables are set, which specifies which I/O operations are logged and
292a block number to watch, respectively. The log messages are sent to
293stderr by default, unless a filename is specified via the
294TEST_IO_LOGFILE environment variable.
295
296
Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400297E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400298===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500299
Theodore Ts'oba142c12003-04-16 00:59:59 -0400300Added a new utility program, logsave, which captures the output of a
301command in a log file, even if the containing directory hasn't been
302mounted yet (in which case the it saves the output in memory until it
303can write out the logfile). This is useful for capturing the
304output of fsck during the boot sequence.
305
306Fixed some portability problems that were causing problems under
307the Cygwin32 environment.
308
309Mke2fs now interprets a negative number to the -b option as a minimum
310block size.
311
312Fixed a bug in mke2fs which was incorrectly checking the argument to
313the -g option if the default block size was used. (Addresses Debian
314bug #188319)
315
316Fsck now explicitly ignores tmpfs and devpts, and it will complain if
317it can not find filesystem checkers for jfs, reseirfs, and xfs.
318
319E2fsck now updates the global free block and inode counters from the
320block group specific counters quietly. This is needed for an
321experimental patch which eliminates locking the entire filesystem when
322allocating blocks or inodes; if the filesystem is not unmounted
323cleanly, the global counts may not be accurate.
324
325Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
3262.0 is not yet supported; this only pulled in the bug fixes: fixed
327possible hangs caused by bugs in calling waitpid, and not setting the
328pipe to non-blocking mode; also fixed a file descriptor leak; made
329sure all functions call log entry/exit functions.)
330
331Badblocks now flushes its output file as bad blocks are discovered.
332
333The uuid library is now more paranoid about assuming the correctness
334of the /dev/random device; it mixes in a stream of bytes from
335random/srandom, just in case.
336
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500337Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -0400338maintainer of e2fsprogs. Other various Debian-specific packaging
339cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500340
341Move the source tarball generation functions from the top-level
342makefile to the util/gen-tarball script.
343
344Updated the Turkish .po translation file.
345
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500346Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500347it more compatible with com_err libraries from those distributions.
348
349Changed dumpe2fs to always display the superblock fields relating to
350the journalling and/or directory indexing feature even if those
351features are not enabled.
352
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500353Updated and clarify copyright statement vis-a-vis alpha releases of
354e2fsprogs.
355
356The ss library will now try to dynamically link to the readline
357library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -0400358the debugfs program now has line editing and history features. The
359SS_READLINE_PATH environment variable is used to find a readline or
360readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500361
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500362E2fsck now finds most duplicate filenames (all when rebuilding all
363directories via the -D option) and offers to delete or rename
364duplicate filenames/directory entries. (Addresses Debian Bug #176814).
365
366Fix bug in e2image. When writing out a raw image file, include data
367blocks from symlinks that do not store the symlink within the inode.
368
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500369Fix bug in resize2fs which incorrectly moved the block and inode
370bitmaps for sparse superblock filesystems and incorrectly marked
371blocks as in use. (Addresses Debian bug #174766)
372
373Added a new shared library, the blkid library, which efficiently
374allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
375and UUID filesystem specifiers without needing to search all of the
376devices in the system. Instead, the device is looked up in a cache
377file, and then verified to make sure the blkid cache is correct.
378
379Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
380the device name, using the blkid library. (Addresses Debian bugs
381#166048, #179671)
382
383Fsck now supports backslash escapes in /etc/fstab so that \040 can be
384used for spaces in device labels.
385
386Removed 32-bit limitations for debugfs's dump command.
387
388If the user specifies a large number of inodes, Mke2fs will
389automatically adjust the number of blocks per group to find a valid
390set of filesystem parameters.
391
392Add workaround to detect broken MD devices where when some of the
393underlying devices are marked read-only, writes to the MD device are
394silently dropped. E2fsck will detect if there is an attempt to run
395the journal twice, and abort with an error if this is the case.
396(Addresses IBM Bugzilla bug #1226)
397
398E2fsck will print an error if more than one of the -p/-a, -n or -y
399options are specified.
400
401E2fsck will fix HTREE corruptions in preen mode, without stopping the
402boot process. This is needed because the 2.4 ext2 filesystem
403accidentally had the INDEX_FL backwards compatibility code removed.
404
405Mke2fs no longer creates filesystems with the dir_index flag set by
406default; the user has to specifically request it.
407
408Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -0400409#173612, #175233, #175113, and #170497, #185945, #188318)

Theodore Ts'o3809bf12003-03-07 01:09:57 -0500413Programmer's notes:
414-------------------
415
416Fix various gcc -Wall nits.
417
418Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500419successfully under Solaris and Apple/Darwin.
420
421Fixed a Makefile dependency to allow building e2fsprogs using parallel
422make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500423
424Changes to create a subset distribution which consists only of the
425et, ss, uuid, and blkid libraries. The configure script and top-level
426makefile were changed to support working with a subset distribution.
427
Theodore Ts'oba142c12003-04-16 00:59:59 -0400428Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
429actually used, and might people who are looking for
430EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
431
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500432Updated debian files to fix a number of Lintian warnings.
433
434Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500435
Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400436Removed unnecessary libraries from being linked into the fsck, lsattr,
437chattr, and blkid executables.

Theodore Ts'o38513012002-11-09 15:00:56 -0500439E2fsprogs 1.32 (Nomvember 9, 2002)
440==================================
441
442Fixed a bug in the Unix I/O routines which caused needless writebacks
443of clean blocks from the unix_io cache (they were erroneously marked
444as being dirty, so they were getting written back to disk before
445getting evicted from the disk cache). This was harmless, but it
446significantly slowed down e2fsck.
447
448Made some other minor optimizations to the Unix I/O routines to save a
449small amount of CPU time.
450
451Updated internationalization files.

Theodore Ts'oae65b292002-11-08 20:08:48 -0500454E2fsprogs 1.31 (Nomvember 8, 2002)
455==================================
456
457Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
458compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
459handling for child process that die unexpectly. Add a hack to force
460mkfs to create filesystems that won't cause problems with hardware
461that has 2k or 4k minimum blocksize requirements. Read from child
462processes in non-blocking mode, so that the GUI continues to update.
463
464Fix e2fsck so that it returns the appropriate exit code when the root
465filesystem has been changed, so that system's rc scripts will be told that
466the system needs to be rebooted.
467
468Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
469was set, some of the descriptor blocks that should have been written
470out were getting skipped.
471
472Changed e2fsck to force out changes to the backup copies of the
473superblock and block group descriptors when important changes are made
474to those data structures.
475
476Fix a bug where e2fsck could erroneously mark a filesystem as being
477clean if a check of dirty filesystem is interrupted with a ^C. (Bug
478introduced in e2fsprogs 1.28.)
479
480If journal debuging is enabled using --enable-jbd-debug, the debugging
481level is now set via the E2FSCK_JBD_DEBUG environment variable.
482
483If byteswapping support is disabled using configure --disable-swapfs,
484skip the tests which depend on byte-swapping, so that "make check"
485won't bomb out.
486
487Lshattr will now display the indexed directory flag. Also, some of
488the more esoteric compression flags are supressed unless compression
489support has been enabled.
490
491Update man pages.
492
493
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500494E2fsprogs 1.30 (October 31, 2002)
495=================================
496
497When resizing a filesystem, and inodes need to moved, resize2fs will
498update the inode's ctime field, and the mtime field of the containing
499directories, so that incremental backups using dump/restore will work
500correctly.
501
502In order to avoid spurious errors, e2fsck wil check the last
503superblock write time to determine whether or not it can safely use
504the LOW_DTIME checks to determine if there are inodes on the orphan
505inode linked list that had somehow gotten disconnected. (Addresses
506Sourceforge bug #620980)
507
508Partition in /proc/partitions that being with the string "lvm" are
509considered real partitions even if they do not end with a number.
510
511Fixed a bug in the the uuid generation function, where if /dev/urandom
512is not present, but /dev/random is, and there isn't sufficient
513entropy, the get_random_byte function could spin a loop forever.
514
515E2fsck, mke2fs, etc. will now reliably notice when image files are
516mounted using the loopback interface. (Addresses Sourceforge bug
517#619119)
518
519When flushing buffers (as is done by badblocks, for example) check to
520see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
521FDFLUSH ioctl which causes the MD device driver which causes confusing
522syslog messages about obselete ioctl messages. (Addresses Sourceforge
523bug #545832).
524
525Debugfs's write command now checks to see if the destination filename
526exists before creating it. (Addresses Sourceforge bug #478195.)
527
528When installing man pages, search for compressed man pages using all
529commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
530
531Fixed a bug in fsck where multiple filesystems specified on the
532command were not being checked in parallel due to a logic bug
533introduced to support the FSCK_MAX_INST environment variable.
534
535We have added a new superblock field, s_mkfs_time, which indicates
536when a filesystem was created. It is set via mke2fs, and printed out
537by dumpe2fs, but is not actually touched by the kernel.
538
539Dumpe2fs has been made more robust by not aborting if there is an
540error reading the block/inode bitmaps; instead it will still print out
541the location of the block/inode bitmaps and inode table.
542
543Add support for the an alternative block group descriptor layout which
544allows for on-line resizing without needing to prepare the filesystem
545in advance. (This is the incomat feature flag meta_bg.)
546
547Add support for storing default mount options in the superblock, so
548that the filesystem can be mounted with specific mount options without
549needing to specify them on the mount command line or in the /etc/fstab
550file.
551
552Add support for a new inode flag, which is to be used for indicating
553the top of directory hierarchies for the Orlov block allocator.
554
555Fix e2fsck so that if it creates the lost+found directory, it does so
556with the more apporpriate permissions of 0700. Also change
557mklost+found so that it also creates the directory 0700.
558
559Fixed format bug in e2fsck if NLS is in use.
560
561Add a German translation for e2fsprogs's NLS support.
562
563Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
564the beginning of the inode table. This won't matter much, since if
565there is a bad block at the beginning of the inode table, the root
566directory won't be available. But at least e2fsck won't crash in this
567case.
568
569Fixed endian problems in the htree code for e2fsck and debugfs.
570
571When byte-swapping a filesystem on a PPC architecture, byte-swap the
572bitmaps since the historical big-endian ext2 variant had byte-swapped
573bitmaps, and the ext2fs library assumes this. This fixes the
574regression test suite on PPC machines.
575
576Fix e2image so that it handles a bad block in the inode table
577appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -0400578
579E2fsck now uses a more sophisticated algorithm to salvage corrupted
580directories that recovers more information in the corrupted directory
581block.
582
583E2fsck now performs additional consistency checks on indexed (HTREE)
584directories.
585
586Fix bug where efsck might get confused about whether a completely
587empty directory block is an empty leaf block or an interior htree
588node. This could cause e2fsck to get confused into think that a valid
589indexed directory was corrupted.
590
591E2fsck no longer creates an empty directory entry at the end of a
592directory block when optimizing a directory. This would cause some
593earlier versions of the dxdir kernel code to corrupt the directory
594when attempting to split a node containing an empty directory entry.
595
596E2fsck could sometimes in rare circumstances leave the indexed flag
597set after a small directory was optimized by compressing it instead of
598indexing it. (This should never happen in real life, since
599directories that small wouldn't have been indexed, but better safe
600than sorry.)
601
602E2fsck now only updates the master superblock in all cases. This
603slightly shortens its run time.
604
605Ext2ed can deal with directory entries of length 0; previously it
606would get stuck in an infinite loop.
607
608Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
609specifiers. (Sourceforge patch #613447)
610
611Badblocks will now work correctly on read-only devices such as
612CD-ROM's. (Sourceforge patch #600451)
613
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500614Updated and clarified man pages. (Addresses Debian bug #167108)

Theodore Ts'oc6633052002-09-24 01:26:50 -0400617E2fsprogs 1.29 (September 24, 2002)
618===================================
619
620Fixed a bug in e2fsck which could corrupt a directory when optimizing
621it (via the -D option) or rebuiliding the hash tree index with a 1 in
622512 probability, due to a fence post error.
623
624Fixed a bug in the LVM support code which caused LABEL='xxx' not to
625work correctly.
626
627Mke2fs now enables the directory indexing flag by default. (Since
628this is a compatible feature flag, it's safe to do so.)
629
630Tune2fs will support setting the directory indexing feature flag. It
631will automatically set up the default hash algorithm and hash seed
632fields in the superblock.
633
634If the bone-headed user enters the root filesystem twice in
635/etc/fstab, the -R option which skips the root filesystem will skip
636all of them. (Addresses Debian bug #159423). Note! This is not a
637precedent for dealing intelligently with any other kind of doubled
638entry in /etc/fstab!
639
640
641Programmer's notes:
642-------------------
643
644Removed perror declaration in lib/et/internal.h. All modern systems
645can be expected to define perror() these days. Besides, the lib/et
646code wasn't using perror at all anyway. :-)
647
648
Theodore Ts'ob7bad612002-08-31 03:00:33 -0400649E2fsprogs 1.28 (August 31, 2002)
650================================
651
652Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
653for setting the htree flag is not included yet, although it can be
654manually turned on via the debugfs program.
655
656Clarified e2fsck error message which is printed when it cannot find
657sufficient contiguous block when relcating filesystem metadata.
658
659Added support for building an EVMS plugin module for ext2/3. This
660module is substantially the same as the EVMS module shipping with EVMS
6611.1, with one or two bugfixes. E2fsprogs can also build this plugin
662for use with EVMS 1.0 (which did not include the ext2 plugin module),
663if the configure --enable-old-evms flag is given.
664
665Fsck will search through EVMS volumes when trying to resolve
666filesystem specifications such as LABEL=xxx or UUID=xxx.
667
668Added a new utility program, /sbin/findfs, which will return
669filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
670the device name.
671
672Update and clarified various man pages. (addresses Debian Bug #145044,
673#146437, #131350, #151990, #144621, #141938)
674
675If there are no filesystems specified on fsck's command line, fsck now
676treat that as if the -As options were given. Previously it would
677simply do nothing. (Addresses Debian Bug #153102)
678
679Mke2fs no longer treats a failure to be able to clear the MD signature
680at the end of the filesystem as a fatal error. (Addresses Debian Bug
681#155007)
682
683The e2p library functions (which are used by lsattr and chattr) now
684double check to make sure the file is a regular file or directory
685before attempting to use the ext2 ioctls. Some device drivers
686unfortunately respond to the ext2 ioctl's with unknown behaviour.
687(Addresses Debian Bug #152029).
688
689The extended attribute handling has been updated to correspond with
690the latest V2 bestbits ACL code.
691
692Fixed bug in e2fsck which caused it to not clear the dtime field when
693processing truncated inodes on the orphan list. This could cause data
694loss(!) if a filesystem is rebooted before a truncate has been
695committed.
696
697E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
698algorithms. This makes e2fsck much faster in the case of severely
699corrupted filesystems where a large number of blocks are claimed by a
700large number of inodes. (Thanks to the 2.5 IDE device driver for
701inspiring this work.)
702
703Resize2fs has been significantly sped up when shrinking and expanding
704a filesystem by a very small number of blocks (for example, when EVMS
705is converting a partition to be an EVMS legacy volume).
706
707Added a new option to e2fsck, -D, which will optimize or compress all
708of the directories in the filesystem.
709
710E2fsck now catches SIGINT and SIGTERM to make sure it will can
711properly clean up and only exit at safe points. Fsck will pass
712SIGINT/SIGTERM to its child processes, and wait until they have all
713exited before it exits.
714
715The uuid parsing code in the uuid library now properly complains when
716an illegally formated uuid is presented to it. (Addresses Debian bug
717#152891)
718
719Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
720and 2.4.17, since the workaround can cause problems when using a 2.4
721kernel with an old version of glibc built with the 2.2 headers.
722
723Fixed a bug in mke2fs where it wasn't properly clearing the initial
724superblock used by other filesystems. (Addresses Debian bug #147256.)
725
726Added support for the synchronous directory feature written by Andrew
727Morton.
728
729The debugfs program can delete directories using the rmdir command.
730
731Add support for 8k and 16k filesystems (for systems with page sizes
732that are greater or equal to 8k or 16k, respectively). Note that
733these filesystems can not be mounted on x86 systems, or other systems
734with only 4k page sizes, due to limitations in the current Linux VM
735code.
736
737Resize2fs requires that the filesystem state be valid and have no
738errors; otherwise, e2fsck -f must be run first. (Previously it simply
739required that the last fsck time be greater than the last mount time.)
740
741Configure now defaults the man pages directory to /usr/share/man on
742Linux systems.
743
744E2fsck now offers to truncate inodes which contain too many blocks (so
745that i_blocks would overflow. Also fixed handling of large sparse
746files.
747
748E2fsck now more completely checks for symlink validity, including
749requiring NULL termination and length checks.
750
751E2fsck will offer to try forcing a disk write to remap a bad block
752after finding a read error when reading a filesystem metadata block.
753
754Fixed a bug in debugfs which caused the -b and -s options to crash
755debugfs, as well as breaking the testb, setb, and clearb functions.
756
757Added a bmap command to debugfs which calculates the logical to
758physical block mapping for a particular inode.
759
760Fixed a bug in code which checked to see if a device was mounted which
761sometimes (rarely) failed in the case of a plain file.
762
763Fixed a bug in resize2fs where when it reported an error, it would
764print a message erroneously indicating that the filesystem had been
765resized before it aborted.
766
767When resizing a plain file which is smaller than the requested size,
768resize2fs will attempt to extended the file so that programs like
769e2fsck will not complain that the file is too small.
770
771Resize2fs will print the actual new size of the filesystem when it is
772finished resizing.
773
774Fixed a bug in debugfs where "ls -l" would report incorrectl file type
775information on big-endian systems.
776
777
778Programmer's notes:
779-------------------
780
781Fixed collisions with C++ reserved words.
782
783Added portability fixes for building e2fsprogs on the HURD and AIX.
784
785Added the ext2ed program for creation of test cases. (ext2ed has many
786limitations and bugs which make it unsuitable for production use.)
787
788The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
789flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
790name_len field is byte swampped on big-endian machines, since in the
791V2 structure, name_len is a char field which is doesn't need to be
792byte swapped --- except if an old-style kernel had byte-swapped the
793name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -0500796E2fsprogs 1.27 (March 8, 2002)
797==============================
798
799The warning messages for mke2fs now go to standard error.
800
801Fixed to make sure "make check" runs all of the test programs with
802LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
803
804The mke2fs program checks the boot sector for the BSD disk label, and
805avoids erasing it if it is there.
806
807Fixed a bug in e2fsck which caused it to core dump if the journal
808inode was missing when it was supposed to be there.
809
810E2fsck now prints ranges in pass 5 when printing deltas for the block
811and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500812
813Debugfs's "ls -l" command now will print out the file type information
814in the directory entry.
815
816Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
817mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
818
819Debugfs can now examine the experimental directory indexing
820information.
821
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500822Fixed bug in debugfs which caused it to core dump if modify_inode is
823called without an open filesystem.
824
825The debugfs lsdel command now runs its output through a pager first.
826
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500827When installing manual pages, remove the compressed manual pages first.
828
829Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
830
831Fix the 2.4 resource limitation workaround introduced in 1.26 which
832actually broke things on mips32, sparc32, and Alpha platforms.
833
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500834Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
835(which is required by the newer libintl libraries).
836
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500837Programmer's notes:
838-------------------
839
Theodore Ts'oa8e77242002-03-08 03:12:14 -0500840Fixed various gcc -Wall complaints.
841
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500842Fixed a few memory leaks in the e2fsck journaling code, and in the
843ismounted code checking for a swap device.
844
845Add new inode I/O abstraction interface which exports an inode as
846an I/O object.
847
848Exported ext2_file_flush as a public interface.
849
850In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
851
852Lots of small random portability fixes to make e2fsprogs build under
853AIX --- even without the 5L compatibility toolkit, and even using the
854uber-crippled AIX native C compiler.

Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500859
Theodore Ts'o446314f2001-12-24 15:22:27 -0500860Dumpe2fs will keep going now if the bad block inode can't be read.
861(Previously it stopped with a fatal error.)
862
863E2fsck will now give an opportunity to run the journal even if the
864recovery flag is not set. This is the default behaviour if e2fsck is
865using a backup superblock, since the needs_recovery flag will never be
866set in the backup superblock copies.
867
868E2fsck now automatically finds the backup superblock/group descriptors
869even when the primary superblock is completely destroyed for 2k and 4k
870filesystems. (Previously it just guessed/assumed that we were dealing
871with a 1k filesystem in that case, and users had to manually specify
872the backup superblock number.)
873
874Fixed a bug in e2fsck where it dereferences a null pointer when there
875is a problem opening a filesystem in preen mode.
876
877E2fsck now handles external journals correctly; previously it trashed
878the external journal device if the journal needed to be replayed.
879
880Work around ulimit incompatibility problem caused by recent 2.4
881kernels; the unix IO module will automatically try to set any resource
882limits to be infinite on startup.
883
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500884Fixed a bug in e2fsck where it wasn't allocating a new block or inode
885bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400886 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500887
888E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
889clearing the new V2 fields if they do not make sense or if the ext3
890superblock is version 1 superblock.
891
892E2fsck will automatically relocate the ext3 journal from a visible
893file (i.e., /.journal) to an hidden inode if the filesystem has been
894opened read/write. This allows the users to add a journal while the
895filesystem is mounted, but the next time the system is rebooted, the
896journal file will disappear. This avoids problems with backups,
897stupid operators with superuser bits, etc.
898
899Fix a bug in fsck where it would not support a filesystem type of
900"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
901
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500902Fsck now supports fstab entries of the form "ext3,ext2". It will also
903automatically identify reiserfs filesystems.
904
905The number of processes spawned by fsck can now be limited using the
906FSCK_MAX_INST environment variable.
907
Theodore Ts'o446314f2001-12-24 15:22:27 -0500908Fsck now searchs the LVM proc hierarchy to find logical volumes which
909should be searched for UUID and label information.
910
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500911Work around a bug in 2.4.10+ kernels by trying to unset the filesize
912limit if at all possible, when opening a block device. (The filesize
913limit shouldn't be applied against writes to a block device.)
914
Theodore Ts'o446314f2001-12-24 15:22:27 -0500915In mke2fs and e2fsck, specifying the -c option twice will now do
916a read/write test on the disk. Update the man pages to encourage
917using the -c option, and to discouraging running badblocks separately,
918since users tend to forget to set the blocksize when running
919badblocks.
920
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500921Mke2fs now automatically clears the immutable attribute on a
922pre-existing .journal file left over from a previous failed attempt to
923add a journal to an alreadyy-mounted filesystem.
924
925Fixed mke2fs's exit codes to consistently indicate when the mke2fs
926operation failed.
927
Theodore Ts'o446314f2001-12-24 15:22:27 -0500928Mke2fs now creates the lost+found directory with permissions of 0700,
929so that files that had previously lived in protected directory are
930safe if they get dropped in lost+found and the system administrator
931doesn't deal with immediately. (Addresses Debian #bug 118443)
932
933Mke2fs and e2fsck (and all programs that use the
934ext2fs_check_if_mounted function) will now properly identify that a
935device is mounted, even in cases where devfs has confused things with
936multiple devices names with the same identity, or if a dim-witted
937system administrator has done something stupid like creating device
938file aliases in their home directory. Also now checks for swap devices
939by using /proc/swaps. (Addresses Debian bug #106622)
940
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500941Added a new option (-T) to tune2fs which sets the time a filesystem
942was last checked.
943
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500944Speed up e2image when creating sparse raw image files by optimizing
945away excess lseek() system calls.
946
947Fix support of large (> 2GB) files when used as a filesystem in
948mke2fs, tune2fs, debugfs, and findsuper.
949
950Debugfs's stat and icheck commands now properly deals with large (>
9512GB) files.
952
953Debugfs's set_super_value command now prints out the list of valid
954superblock fields which can be set using the command.
955
Theodore Ts'o446314f2001-12-24 15:22:27 -0500956Debugfs's rm and kill_file command now updates the superblock free block
957and inode counts, thus keeping the filesystem consistent.
958
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500959Debugfs's lsdel command now takes an optional argument which allows
960the user to only see the most recently deleted files.
961
962A new command (undel) was added to debugfs which automates
963undeleting a deleted inode and linking it back to a directory.
964
965Debugfs's ls command now takes a new option, -d, which lists
966deleted directory entries.
967
968Debugfs's testb, freeb, setb, and find_free_block commands now take an
969optional count argument.
970
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500971Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
972be used to signal that a particular inode should not be eligible for
973tail-merging --- this is needed for programs like LILO.
974
975The findsuper (an unreleased, uninstalled utility program) has been
976improved to add extra validity checks and to add a progress meter.
977(It is still an unsupported program; the officially supported way to
978recover from a trashed partition table is to use gpart; findsuper is
979for wizards only. :-)
980
981Debugfs was fixed to compile with "configure --disable-swapfs".
982
Theodore Ts'o446314f2001-12-24 15:22:27 -0500983Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500984
985Added new translation file for Turkish.
986
Theodore Ts'o446314f2001-12-24 15:22:27 -0500987Programmer's notes:
988-------------------
989
990Fix general gcc -Wall complaints.
991
992E2fsprogs (mostly) works with the dietlibc.
993
994The programming texinfo file has been expanded to include description
995of additional libext2fs functions. (Still not compeltely done, but a
996lot of the more important functions have been documented.)
997
998Added a umask structure to struct_ext2_filsys, which currently only
999modifies the behaviour of ext2fs_mkdir(), but if we add any file
1000creation functions to libext2fs, we should also make sure they respect
1001the umask setting.
1002
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001003The build-rpm script was fixed to be a bit more safe.
1004
1005The tests' Makefile now has a way of automating test case creation
1006for e2fsck, using "make testnew".
1007
1008Created a new function, ext2fs_dir_iterate2 which passes more
1009information to the callback function (identical to the one used by
1010ext2fs_dblist_dir_iterate). The directory iterator functions take a
1011new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1012directory entries. If the directory entry is deleted, the callback
1013function will be called with the entry paraemter set to
1014DIRENT_DELETED_FILE.
1015
1016Added new functions, ext2fs_inode_alloc_stats and
1017ext2fs_block_alloc_stats, which takes updates block/inode allocation
1018statistics in the bitmaps, block group descriptors, and superblock
1019when inodes or blocks are allocated or deallocated.
1020

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04001022E2fsprogs 1.25 (September 20, 2001)
1023===================================
1024
1025This is primarily a bug-fix release; no new features were added, but
1026there are a number of embarassing bug fixes and cleanups applied.
1027
1028Fix a bug mke2fs which causes stack garbage to be written to disk when
1029zapping disk sectors. (This bug could cause mke2fs to core dump for
1030some kernels, I suspect with security enhancement patches.)
1031
1032Remove unneeded #include of <linux/config.h> which was breaking
1033building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1034
1035Updated tune2fs man page to reflect the fact that adding or removing a
1036journal doesn't require running e2fsck.
1037
1038Remove use of AC_REQUIRE from autoconf which had been used to prevent
1039AC_CANONICAL_HOST from being called twice; unfortunately this causes
1040recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1041used outside of autoconf macros. Fortunately, it doesn't seem to be
1042necessary any more, anyway.
1043
1044E2fsck will now not fall back to an alternate superblock if the user
1045specifies the superblock location explicitly on the command-line.
1046This allows easier recovery from a situation where the primary
1047superblock and block groups are slightly corrupted, but the backup
1048superblocks are completely broken.
1049
1050Fix problem which caused compile_et and mk_cmds to blow up if
1051e2fsprogs was in a directory with a pathname that contained spaces.
1052
1053We are now more paranoid about checking the entry in /etc/mtab to make
1054sure the filesystem is really mounted, since some broken distributions
1055(read: Slackware) don't initialize /etc/mtab before checking non-root
1056filesystems. (Slackware also doesn't check the root filesystem
1057separately, and reboot if the root filesystem had changes applied to
1058it, which is dangerous and broken, but there's nothing I can do about
1059that.)
1060
1061Make UUID library C++ friendly by adding appropriate extern "C"
1062declarations and using const in the function declarations.
1063
1064Fix up the com_err texinfo file so that it can product a valid info
1065file (previously, it could only be used to generate paper
1066documentation using texinfo.tex).
1067
1068
Theodore Ts'ofb707752001-09-04 15:00:37 -04001069E2fsprogs 1.24a (September 2, 2001)
1070===================================
1071
1072Fix brown-paper bug in mke2fs which caused it to segfault when
1073printing the version string.
1074
1075
Theodore Ts'o109624a2001-08-31 00:59:55 -04001076E2fsprogs 1.24 (August 30, 2001)
1077================================
1078
1079Revert the BLKGETSIZE64 support, since for some distributions, this
1080ioctl has been used by an unofficial kernel patch to update the last
1081sector on the disk, and this was causing disk corruption problems as a
1082result.
1083
1084Mke2fs is now more careful about zapping swap space signatures and
1085other filesystem/raid superblock magic values so that programs like
1086mount who try to use hueristics to determine the filesystem type of a
1087partition are less likely to be confused.
1088
1089E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1090regular file (since Andreas Dilger's on-line resizing tools will set
1091its mode bits).
1092
1093Fixed some minor texinfo, man pages nits for spelling errors,
1094texinfo warnings, etc. (Addresses Debian bug #110621.)
1095
1096E2fsprogs program no longer print the filesystem version number
1097(i.e. 0.5b), since it only confuses people and doesn't serve any real
1098purpose.
1099
1100E2fsck will once again compile under libc5, since it will supply its
1101own version of strnlen if necesssary.
1102
1103mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1104when specifying the external journal device. tune2fs will also search
1105devices looking for the externla journal debice when removing.
1106
1107E2fsprogs 1.23 (August 15, 2001)
1108================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001109
1110Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001111correctly handle a filesystem with EA's and check the EA blocks for
1112corruptions.
1113
Theodore Ts'od494bba2001-08-09 06:14:42 -04001114E2fsck's symlink sanity checking has been cleaned up. It now checks
1115the i_size value of fast symlinks, and checks for immutable flags
1116being set of symlinks, etc.
1117
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001118E2fsck now offers to clear inodes which are special files that have a
1119non-zero i_blocks or i_size field. (The i_size field check was in the
1120previous version of the code, but due to a bug it didn't offer to
1121clear the inode unless i_size and i_size_high were both non-zero.)
1122
Theodore Ts'od494bba2001-08-09 06:14:42 -04001123E2image can now create "raw" image files, which only contain the
1124filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1125debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001126
1127Add support for the 64-bit block device patches.
1128
1129Fixed bugs in creating external journals with a 1k blocksize.
1130
Theodore Ts'od494bba2001-08-09 06:14:42 -04001131Add initial support for external journals (so long as the external
1132journal only supports a single filesystem) in e2fsck.
1133
1134Remove requirement for needing to run fsck on a filesystem after
1135removing a journal (either internal or external).
1136
Theodore Ts'obf16d102001-07-27 22:20:06 -04001137The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001138
1139Speed up the check of an ext3 filesystems by avoiding a needless flush
1140of all of the superblock and block group descriptors.
1141
Theodore Ts'od494bba2001-08-09 06:14:42 -04001142Speed up creating an internal journal using tune2fs in the case where
1143the filesystem has a lot blocks already allocated.
1144
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001145Tune2fs has been fixed to make sure that only error messages go to
1146stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1147
Theodore Ts'od494bba2001-08-09 06:14:42 -04001148Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001149now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04001150
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001151Add support in fsck for the filesystem type "auto".
1152
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001153Fsck -A will not try to interpret device names for filesystems which
1154have a pass number is 0. (Addresses Debian bug #106696).
1155
1156Fsck prints a warning message if now valid filesystems are passed to
1157it. (Addresses Debian Bug #107458.)
1158
Theodore Ts'o9249d982001-07-20 18:14:10 -04001159E2fsck now gives an explicit warning if there filesystem still has
1160errors at the end of the run. (Addresses Debian bug #104502)
1161
Theodore Ts'od494bba2001-08-09 06:14:42 -04001162E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001163reflects an error. E2fsck will also not run the orphan list if the
1164filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04001165
1166E2fsck now prints the number of large files when given the -v option.
1167
1168Fixed minor memory leaks in e2fsck.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001169
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001170Some minor man pages updates. (Addresses Debian bug #30833, #108174)
Theodore Ts'o9249d982001-07-20 18:14:10 -04001171
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001172
Theodore Ts'o19d6b542001-06-23 00:13:09 -04001173E2fsprogs 1.22 (June 22, 2001)
1174==============================
1175
1176Fixed a bug in e2fsck's handling of orphan inodes which are special
1177files (i.e., block/character device files, named FIFO's, etc.).
1178
1179Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1180tune2fs to fail at adding a journal to a mounted filesystem.
1181
1182Fixed a few big-endian bugs in e2fsprogs
1183 * The directory block functions were accidentally reporting
1184 some directories as corrupted when they weren't.
1185 * If e2fsprogs is compiled --disable-swapfs, the C language
1186 equivalents weren't being included for big-endian platforms.
1187 (Fixes Debian bug #101686).
1188
1189Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1190
1191Programmer's notes:
1192-------------------
1193
1194Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1195ioctls, and allow them to be defined for non-i386 platforms.
1196
1197The uuid.h header file is now protected against multiple inclusions.
1198
1199E2fsprogs is now being developed using BitKeeper. Changed the test
1200scripts to deal with BK's stripping CR characgters from text files,
1201and changed the top-level Makefile.in to avoid including BitKeeper
1202files when generating the source tarball.
1203
1204
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001205E2fsprogs 1.21 (June 15, 2001)
1206==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00001207
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001208Added new configure flags which allow a subset e2fsprogs to be built;
1209this is most useful for boot floopies, since the resulting shared
1210libraries and programs are slimmed down by removing features that
1211aren't necessary for a boot floppy. The new flags that were added
1212are: --disable-swapfs, which removes support for byte swapping old
1213legacy PPC/68k filesystems, --disable-debugfs, which removes support
1214for debugfs from the libext2fs library, --disable-imager, which
1215removes support for the e2image program, and --disable-resizer, which
1216removes support for resize2fs.
1217
1218E2fsck now prints the number of mounts or days elapsed since the last
1219check when e2fsck is forced to check an otherwise clean filesystem.
1220
1221Tune2fs now prints an informative message about how often a filesystem
1222will be checked when adding a journal to the filesystem, to remind the
1223user that he/she may want to adjust those parameters using tune2fs
1224-c/-i.
1225
1226Worked around hurd brain-damage which causes e2fsck to sometimes
1227believe a filesystem is the root filesystem based on device numbers
1228(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1229violation).
1230
1231Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1232erroneous error with the -F option was specified.
1233
1234Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001235ext3 0.7a.
1236
Theodore Ts'o767de092001-06-02 01:20:18 +00001237Fixed two bugs in e2fsck's handling of dup block handling, dealing
1238with relatively uncommon edge cases: a directory with an indirect
1239block which is claimed by another file, and when the last inode in the
1240filesystem has blocks claimed by another file.
1241
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00001242E2fsck now checks to see if the i_size field of a fast symlink is too
1243big, and offers to clear the symlink if so.
1244
1245E2fsck now checks to see if i_size_high of special files is non-zero,
1246and offers to clear i_size_high.
1247
Theodore Ts'o767de092001-06-02 01:20:18 +00001248Fix e2fsck's handling of incompatible journal flags so that the user
1249has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00001250entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00001251
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001252Fixed a bug in fsck which could cause it to core dump if a mix of
1253standard and non-standard device names are used in /etc/fstab.
1254(Debian bug #100559)
1255
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001256Fixed a bug in debugfs which caused read errors when copying a file to
1257not be noticed.
1258
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001259The debugfs set_super_value command can now modify the s_lastcheck field.
1260
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001261Fixed a bug in lsattr and chattr which was accidentally introduced in
12621.20 to support > 2GB files; both lsattr and chattr wasn't reading
1263directories correctly because the change modified the layout of struct
1264dirent to be incompatible with the libe2p shared library.
1265
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001266Cleaned up the mke2fs manual page and included a discussion about why
1267it's good to periodically check the filesystem even when journaling is
1268enabled.
1269
Theodore Ts'o767de092001-06-02 01:20:18 +00001270Programmer's notes:
1271-------------------
1272
1273Fix general gcc -Wall complaints.
1274
1275The types needed by the ext2 header files are now provided by
1276lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1277
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001278Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001279in ext2_types.h. Also, if linux/types.h has already been defined,
1280don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001281
Theodore Ts'o767de092001-06-02 01:20:18 +00001282Fixed make depend script so that it automatically corrects the
1283pathname cleanups performed by make -M, so I don't have to fix them up
1284by hand.
1285
1286Fixed the d_loaddump test case to be more robust, and not depend on
1287bash'isms.
1288
1289Removed debugfs's dependence on pread(), which was accidentally
1290intrudced in e2fsprogs 1.20
1291
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001292Fixed a performance bug in the libext2fs's icount routine; the size
1293estimate of the icount array was incorrectly being calculated.
1294
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001295Removed use of the badblocks compatibility functions in the e2fsprogs
1296programs.
1297
1298Added paranoia code which protects against strange cases where /etc
1299isn't on the root filesystem, or if /etc/mtab doesn't exist.
1300
1301The header file ext2_types.h is now installed.
1302
1303Autoconf is used to determine when we are on big-endian machines,
1304instead of doing run-time tests, to save a few bytes of code.
1305
1306The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1307functions are no longer inline functions, which saves space and
1308doesn't really cost any real performance.
1309
1310The ext2fs library no longer depends on the e2p library. (What need
1311there was of it --- namely, fsetflags, was coded in-line).
1312
1313Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
1314when the user is stupid and tries compiling the package using "make
1315install" as root.
1316
1317Miscellaneous code cleanups:
1318 * Added missing files from Makefile.in's SRCS file, so that
1319 their dependencies would be properly calculated.
1320 * Removed redundant code
1321 * Fixed comments in code
1322 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001325E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001326=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00001327
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001328Add support for replaying the ext3 journal purely in user mode,
1329including handling the orphaned inode list. Used code contributed by
1330Andreas Dilger, with bug fixes and the orphaned inode handling done
1331by Theodore Ts'o.
1332
1333The mke2fs and tune2fs programs can create or modify a filesystem to
1334include an ext3 journal. Tune2fs also can be used to remove an ext3
1335journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001336
1337E2fsck will now check for the existence of a linked list of orphan
1338inodes in the superblock, and clear those inodes before starting the
1339rest of the filesystem check (but after the journal playback).
1340
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001341E2fsck now validates the file descriptor passed to the -C option,
1342which saves against the completion bar getting written to an
1343unexpected location, such as the disk being checked. (Debian
1344bug/wishlist #55220)
1345
1346E2fsck will now bump the filesystem revision number from zero to one
1347if any of the compatibility bits are set.
1348
1349Fixed a bug where a badly corrupted directory on a big endian system
1350could cause e2fsck to die with a bus error. The
1351ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
1352the ext2 library now does alignment sanity checks on the rec_len field
1353of the directory entry before using it.
1354
1355The ext2 library has been enhanced to make tune2fs safe to run on
1356mounted filesystems. (Users could usually get away with using tune2fs
1357on mounted filesystems before, but with the advent of ext3 and
1358journaling, it became important to make tune2fs was *really* safe for
1359use even when the filesystem being modified is mounted.) E2label is
1360now implemented by tune2fs using an argv[0] dispatch, so that e2label
1361is also now safe for use on mounted filesystems.
1362
1363Added a new program, e2image, which creates a backup of critical ext2
1364filesystem data structures. The generated image file can be examined
1365using dumpe2fs and debugfs. In the future, e2fsck will be able to use
1366the image file to help recover very badly damaged filesystems.
1367
1368Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
1369no longer cause e2fsck to bomb out. Also treat files > 2GB as being
1370large file when deciding whether or not the filesystem has large files.
1371
1372Fixed lsattr and chattr so that they work correctly on large files.
1373(Fixes Debian bug #72690.)
1374
1375Removed limitation in get_device_size() which imposed a one terrabyte
1376filesystem limitation. (Most 2.2 kernels still have a signed int
1377problem which cause 1 TB block device limitation. Fortunately, the
1378kernel patches to fix this are much easier than fixing the 2TB
1379limitation in the kernel. :-)
1380
1381A max_mount_count of zero is now treated as if no mount count were
1382set. (Previously, no mount count was indicated by using -1, and a
1383mount count of zero caused e2fsck to always be run.)
1384
Theodore Ts'o77648562001-05-14 13:04:44 +00001385Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001386
1387Mke2fs now adds some randomness in s_max_mount_count so that multiple
1388filesystems won't be all checked at the same time under normal
1389operations.
1390
Theodore Ts'o5570a652000-08-21 01:23:39 +00001391Fixed bug in the progress bar printing code which could cause e2fsck
1392to core dump on an illegal filesystem.
1393
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001394Fixed bug in fsck which could allow more than one instance of e2fsck
1395to be printing a progress bar. (Debian bug #65267)
1396
Theodore Ts'o5570a652000-08-21 01:23:39 +00001397Fsck using a UUID or a LABEL specifier will work even if devfs is
1398compiled into the kernel and not mounted. If the pathnames in
1399/proc/partitions are incorrect, fsck will search /dev for the correct
1400device (using the new ext2fs_find_block_device library function).
1401Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001402found when they are in use. Support has also been added to support
1403additional IDE disks and the DAC 960 device names. (Debian bug #94159)
1404
1405Fixed a bug in fsck which caused it not deal properly with 16
1406byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001407
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001408Fsck's -t option has been made a lot more flexible. The semantics for
1409what happens if a comma-separated list to fsck has been regularized,
1410and it is now possible to filter what filesystems will get checked
1411based what is in the filesystem's fstab entry's option field. (Debian
1412bug #89483.)
1413
Theodore Ts'o5570a652000-08-21 01:23:39 +00001414The dumpe2fs program can now print out the group description
1415information in hex, and also prints the location of the superblock and
1416block group descriptor for those block groups that have them.
1417
1418Mke2fs now clears the ext2 superblock before it starts creating a
1419filesystem, so that the superblock magic number is only written if the
1420filesystem creation process successfully completes.
1421
1422The debugfs program's stat command now pretty-prints the blocks used
1423by an inode so that it's more compact and informative.
1424
1425The debugfs stats command now uses the same libe2p code (which is used
1426by dumpe2fs) to print the superblock header information. This is more
1427complete, and it avoids a bit of code duplication.
1428
1429Added a new debugfs command, set_super_value (ssv) which allows the
1430user to set arbitrary superblock fields.
1431
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001432Debugfs was extended to support inode numbers in hex (by prefixing
1433them with 0x), and so that modify_inode can set the inode generation
1434number. Also, there is now a new function command called logdump
1435which will dump an ext3 journal.
1436
1437Fixed a bug in debugfs so that quitting out of the pager doesn't kill
1438debugfs.
1439
1440Debugfs's dump command now stops immediately upon reporting a disk
1441read error. (Fixed a bug in ext2fs_file_read library routine which
1442caused debugfs not to stop.) (Debian bug #79163)
1443
1444On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
1445checked before /etc/mtab is used, since /proc/mounts is more likely to
1446be accurate.
1447
1448Added portability fixes for Solaris and Linux/ia64.
1449
1450Various manual pages were clarified and cleaned up. (Fixed debian
1451bugs #63442, #67446, and #87216)
1452
Theodore Ts'o5570a652000-08-21 01:23:39 +00001453
1454Programmer's notes:
1455-------------------
1456
1457The e2fsck message printer now supports %Iu and %Ig, which will print
1458out the inode's user and group owners, respectively.
1459
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001460E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
1461that no longer dependent on the system having the correct version of
1462the kernel header files.
1463
Theodore Ts'o5570a652000-08-21 01:23:39 +00001464Added a new function to libext2, ext2fs_find_block_device(), which
1465searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
1466device given its device number.
1467
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001468Added a new function to libext2, ext2fs_sync_device, which centralizes
1469all of the places which might try to use the BLKFLSBUF or FDFLUSH
1470ioctls (and usually failing to define them since the system header
1471files don't usually do this for us, and we're trying to avoid usage of
1472kernel include files now).
1473
Theodore Ts'o5570a652000-08-21 01:23:39 +00001474Added new utility programs in tests/progs: random_exercise and
1475hold_inode. They aren't built by default; they're useful for
1476exercising ext3 filesystem code.
1477
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001478Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
1479the filesystem close functions to only update the superblock, and to
1480not touch the block group descriptors. Needed by tune2fs when
1481modifying a mounted filesystem.
1482
1483Got rid of struct ext2fs_sb and replaced it with the standard struct
1484ext2_super_block from include/linux/ext2_fs.h. Note: this may break
1485source (but not binary) compatibility of some users of the ext2
1486library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00001487replace of struct ext2fs_sb with struct ext2_super_block, and include
1488the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001489
1490The ino_t type has been renamed ext2_ino_t to protect applications
1491that attempt to compile -D_FILE_OFFSET_BITS=64, since this
1492inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
1493unexpected ABI change.
1494
1495The Makefiles have been reworked so that "make check" can be run from
1496the top-level Makefile.
1497
1498Fix general gcc -Wall complaints and removed dead code.
1499
1500Remove use of NOARGS, because we assume everyone does ANSI C these
1501days.
1502
1503Added build-rpm script from sct.
1504
1505New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
1506to support e2image.
1507
1508New function ext2fs_flush_icache which must be called if the
1509application program modifies the inode table blocks without going
1510through ext2fs_write_inode() interface.
1511
1512New ext2fs_check_mount_point() function, which will return the mount
1513point of a device if mounted.
1514
1515The io_channel abstraction now has an optional interface,
1516io_channel_write_range, which allows specific byte ranges to be
1517written.
1518
1519The unix_io IO channel now supports write-through caching, so that
1520journal creation is more efficient.
1521
1522Added x86 assembly language routines to support byte swapping, to
1523reduce executable size.
1524
1525Fixed bug in the utility program subst so that it's possible to
1526replace a substitution variable with a zero-length string.
1527
1528Fixed numbering e2fsck pass1 problem numbers; an extra zero had
1529slipped into some of the problem number.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001530
Theodore Ts'ob777e262000-07-27 01:39:23 +00001531E2fsprogs 1.19 (July 13, 2000)
1532==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00001533
1534Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00001535be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00001536
1537Add experimental support needed for the ext2 compression patches.
1538This requires compiling e2fsprogs with the --enable-compression flag
1539to the configure script.
1540
1541Added ext3 journalling support. E2fsck will run the journal (if
1542necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
1543installed as a symlink to e2fsck. Fsck has been taught about ext3,
1544and treats it the same as ext2 in terms of the progress bar logic.
1545Dumpe2fs will display the superblock journaling information if the
1546filesystem has a journal. The ext2 library will now permit opening an
1547ext3 filesystem with the recovery flag set. This is necessary for
1548on-line dump's to work correctly, but there may be issues with this
1549working well since ext3 is much less agressive about syncing blocks to
1550the filesystem, since they're safe on the journal.
1551
1552Tune2fs and e2fsck have been changed to allow the mount_count check to
1553be disabled by setting max_mount_count to -1. (This was already
1554supported by the kernel.)
1555
1556Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
1557are used for ext3 as well.
1558
1559Added internationalization support for e2fsprogs; must be enabled
1560by passing --enable-nls to configure.
1561
1562Always use the provided ext2fs header files to insulate ourselves from
1563kernel version changes. Which include files are used by e2fsprogs
1564have also been cleaned up to improve portability.
1565
1566Limit the number of times that e2fsck updates the progress bar so that
1567people who are booting using a 9600 baud console don't get swampped by
1568too many updates.
1569
1570Improved the loop detection algorithm in e2sck's pass #3 so that it is
1571much, much faster for large filesystems with a large number of
1572directories.
1573
1574The memory footprint for e2fsck is now slightly smaller than before.
1575
1576E2fsck now checks if special devices have a non-zero size, and offers
1577to clear the size field if it finds such an inode.
1578
1579E2fsck now checks if special devices have the append-only flag set,
1580and offers to clear the inode.
1581
1582E2fsck now properly handles some "should never fail" cases during a
1583bitmap copy in pass5.
1584
1585E2fsck now properly prints control characters in filenames as ^A .. ^Z.
1586
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001587E2fsck now calculates the correct location of the backup superblock in
1588the case of filesystem blocksizes > 1k.
1589
1590Fixed a bug in e2fsck's calculation of the number of inodes_per_block
1591which normally didn't cause problems under most filesystem parameters,
1592but could cause a valid superblock to be rejected in extreme cases.
1593Other checks for validating superblock values were made more
1594stringent.
1595
Theodore Ts'oab146762000-07-07 04:37:35 +00001596Added non-destructive write testing to the badblocks program, courtesy
1597of David Beattie. The badblocks also now has an option to input the
1598current set of bad blocks, so that known bad blocks are skipped to
1599speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00001600feature which causes badblocks to run until it has completed some
1601number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00001602
1603Badblocks now checks to see if the device is mounted and refuses to do
1604the tests involving writing to the device if it is mounted. Also,
1605badblocks now allows the number of blocks to be checked to be
1606defaulted to the size of the partition.
1607
1608Fixed a bug in fsck which didn't allow non-root users to be able to
1609check filesystems if there were any LABEL= or UUID= entries in
1610/etc/fstab.
1611
1612The Hurd doesn't support the filetype filesystem feature. The mke2fs
1613program now makes sure that for the Hurd, the filestype feature is
1614turned off. E2fsck will check to see if the filetype feature is
1615turned on for Hurd filesystems, and offer to turn off the feature.
1616
1617Mke2fs now has a safety check to make sure the number of blocks do not
1618exceed 32 bits even on a 64 bit platform.
1619
1620Really fixed a bug in fsck to allow "fsck -As" to run interactive
1621fsck's. (For those people who like to do interactive fsck's in the
1622/etc/rc scripts!?!)
1623
1624Debugfs has a few new features: the rdump command, which will do a
1625recursive dump of a directory and all of its contents, and the lcd
1626command which does a local chdir (much like the ftp command of the
1627same name). In addition, the debugfs program and the open_filesystem
1628command now takes three new options: -b and -s, which allows the
1629blocksize and superblock location to be specified, and the -c option
1630which is used in catastrophic situations where the block group
1631descriptors are corrupt. If the -c option is specified, debugfs will
1632skip trying to read in the block and inode bitmaps.
1633
1634Debufs's lsdel command was fixed to handle bad blocks in the inode
1635table.
1636
1637A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
16384 digit years.
1639
1640General improvements in error messages
1641
1642 - Mke2fs prints a sane error message if the partition size is zero
1643 (usually because the partition table wasn't reread by the
1644 kernel due to the partition being busy), instead of "invalid
1645 argument passed to ext2 library while initializing superblock".
1646
1647 - Fsck now prints more self-explanatory message if an invalid UUID=
1648 or LABEL= specification is passed to it.
1649
1650UUID library changed to use the LGPL.
1651
1652Fixed a bug in the UUID library where very rapid calls to the
1653time-based UUID generator could cause duplicate UUID's to be returned.
1654This was not a problem for e2fsprogs, but it could be a problem for
1655other users of the library.
1656
1657Make the UUID library more robust in the face of missing or an
1658improper /dev/urandom or /dev/random files.
1659
1660Added some random portability fixes for Solaris.
1661
1662Some minor man page updates.
1663
1664Fixed a memory leak in the ss library.
1665
1666
1667Programmer's notes:
1668-------------------
1669
1670We now try to use lseek64 and open64 from the LFS if possible.
1671
1672The 3rd parameter in e2p's print_flags is now a flags word, instead of
1673a boolean option.
1674
1675The mark and unmark bitmap functions now return the previous state of
1676the bit that was being changed, which is useful for some speed
1677optimizations.
1678
1679The following functions have been added to enhance the badblocks list
1680handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1681ext2fs_badblocks_equal.
1682
1683The ext2 header files now have the latest journalling fields to the
1684superblock.
1685
1686The ext2fs_mkdir function in libext2fs now properly backs out of error
1687conditions robustly.
1688
1689Cleaned up makefiles:
1690 - to cleanly compile with the -j flag.
1691 - so distclean removes all generated files.
1692 - so in case of an error while installing header files, the make aborts.
1693
1694Fix test_script so that it works correctly when compiling in the
1695source directory.
1696
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001697The random UUID generation routine has been made slightly better in
1698the case where /dev/random doesn't exist. (Use of randomly-based UUID
1699is still not recommended if /dev/random doesn't exist, however; it's
1700better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00001701
1702Clean up the build process so it's more friendly in case of missing
1703directories.
1704
1705The ext2fs header file can now be #include'd into C++ programs.
1706
1707The e2p.h header file is now installed.
1708
1709Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.

Theodore Ts'o24ded091999-11-10 15:56:16 +00001713E2fsprogs 1.18 (November 10, 1999)
1714==================================
1715
1716Fix a core dumping bug in e2fsck if an imagic inode is present or
1717(more rarely) if the filesystem is badly corrupted enough that e2fsck
1718has to restart pass 1 processing. E2fsck now closes the filesystem
1719before freeing a large number of its data structures, so in the case
1720of future memory faults, at least the fixed filesystem will be fully
1721written out.
1722
1723If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1724imagic inode, it will offer to clear the imagic flag.
1725
1726E2fsck will now offer to clear the immutable flag on special files
1727(device/socket/fifos) when running it in non-preen mode.
1728
1729E2fsck will now set the filetype when creating /lost+found, and when
1730connected orphaned inodes to /lost+found.
1731
1732Debugfs's ncheck and icheck commands now handles the case where there
1733are bad blocks in the inode table without bombing out.
1734
1735The badblocks list processing code has been made more efficiently for
1736appending a large number of (ordered) badblocks to the badblocks list.
1737
1738Some minor man page updates.
1739
1740Fsck now allows interactive e2fsck's when using fsck -As (not a common
1741mode, but some people like to do this in boot scripts for silly reasons).
1742
1743Programmer's notes:
1744-------------------
1745
1746The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1747with the problem code convention.
1748
1749The badblocks list regression test program has been updated to work
1750with previously made API name changes.
1751
1752The ext2fs_free() command now uses the new badblocks API to avoid
1753using the compatibility layer.
1754
1755Added new regression test cases; the run_e2fsck test script now
1756supports the ability for a test case to run a prepratory command
1757before running e2fsck.
1758
Theodore Ts'o28e11941999-10-26 18:17:20 +00001759E2fsprogs 1.17 (October 26, 1999)
1760=================================
1761
1762Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1763infinite loop.
1764
1765Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1766thus potentially causing problems if a binary UUID contained a NULL
1767character.
1768
1769E2fsck now uses stricter checks for directory entries in pass 2:
1770zero-length filenames are not allowed; neither are 8 byte long
1771directory entries.
1772
1773The debugfs "dirty" command now clears the filesystem valid bit.
1774(Previously this just set the dirty-as-in-needs-writing-out-to-disk
1775bit in the in-core superblock image. The new functionality is more
1776what the user expects, and is more useful.)
1777
1778Added a debugging hook to test parallel fsck; if the environment
1779variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1780will be checked in parallel when they normally would not be.
1781
1782Programmer's notes:
1783-------------------
1784
1785Fixed some #ifdef's for compilation under the Hurd OS.
1786
1787Fixed minor W2K compatibility problems.
1788
1789Fixed some miscellaneous GCC warnings.
1790
1791
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001792E2fsprogs 1.16 (October 22, 1999)
1793=================================
1794
1795Fixed a race condition bug in fsck; when printing a progress bar, if
1796checking multiple filesystems in parallel, it was possible for fsck to
1797send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
1798handler, which would cause it to terminate with a signal 10.
1799
1800E2fsck now properly handles filesystems that have the
1801INCOMPAT_FILETYPE feature turned on. It can be used to convert a
1802filesystem into using or not using FILETYPE feature.
1803
1804E2fsck now properly handles filesystems that have the IMAGIC feature
1805turned on (this is used on Linux AFS servers).
1806
1807The mke2fs program now creates filesystems that have the filetype and
1808sparse_superblock features enabled by default, unless it is run on a
1809pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
1810so there is now a new flag -O which allows the user to specify with
1811which features she would like to create the filesystem; "mke2fs -O
1812none" will create a filesystsem compatible with 2.0 kernels.
1813
1814The tune2fs program now has a -O option which allows the user to set
1815and reset "safe" filesystem features. Currently, the only ones which
1816allows to be modified are the filetype and sparse_superblock features.
1817Note setting or clearing either feature will require running e2fsck on
1818the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
1819requires that there is enough free space on the filesystem for the
1820extra superblocks which will be created by e2fsck.)
1821
1822Debugfs can now set and print filesystem features in the superblock
1823using the "features" command. Dumpe2fs will print out the complete
1824set of features when listing the superblock.
1825
1826Dumpe2fs has new options -f (force) and -h (header-only).
1827
1828Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
1829message to come up. This could happen when decrementing or
1830incrementing a link count could result in an overflow.
1831
1832Fixed a bug in e2fsck where the block count on the lost+found
1833directory would not be properly incremented when the directory was
1834expanded to the point where an indirect block needed to be allocated.
1835
1836E2fsck now makes some additional sanity checks on the superblock to
1837avoid crashing or giving a memory allocation error if some of the
1838values in the superblock are unresonable (but the superblock otherwise
1839looks valid).
1840
1841Fixed a bug in e2fsck where a very badly corrupted filesystem might
1842require two passes to completely fix the filesystem. This happened if
1843an inode claimed blocks that was part of the filesystem metadata
1844(typically, when garbage was written into an inode table or indirect
1845block, since this kind of filesystem corruption normally doesn't
1846happen otherwise).
1847
1848On the Alpha, glibc declares st_flags although it isn't actually used;
1849the configure script was improved to detect this case so that
1850e2fsprogs can avoid using the non-functional stat field.
1851
1852The manual pages were updated to use a more consistent formatting
1853style consistent with standard Unix man pages. Mke2fs's man page
1854added documentation for a few previously undocumented options.
1855
1856Fixed minor display bugs in tune2fs and mke2fs.
1857
1858Programmer's notes:
1859-------------------
1860
1861Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
1862
1863Added features to parse and print feature strings into the e2p library.
1864(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
1865
1866ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
1867whose directory entries contain proper filetype information if the
1868filesystem supports it.
1869
1870ext2fs_link() now uses the low 3 bits of its flags parameter to pass
1871the directory entry filetype information. This is used to set the
1872directory entry filetype information if the filesystem supports it.
1873
1874Fixed a bug in ext2fs_expand_dir() where the block count in a
1875directory's inode would not be properly incremented when the directory
1876was expanded to the point where an indirect block needed to be
1877allocated.
1878
1879
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001880E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001881==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001882
1883Add configuration checks so that e2fsprogs will compile cleanly on
1884Linux 2.3 kernels that have renamed i_version to i_generation.
1885
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001886E2fsck now prints a progress/completion bar (and not just a simple
1887spinner) if the -C0 option is requested or if it receives a SIGUSR1
1888signal. Fsck will automatically manage the (potentially muliple)
1889e2fsck processes to print completion bars if it is given a -C option,
1890with the right thing happening if multiple filesystems are being
1891checked in parallel.
1892
1893Mke2fs now has better automatic hueristics to determine the filesystem
1894parameters to be used for a particular filesystem. Added a new option
1895-T which allows the user to specify how the filesystem is to be used,
1896which helps mke2fs do a better job selecting the filesystem parameters.
1897
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001898Mke2fs now creates revision 1 filesystems by default, and with the
1899sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001900not understood by Linux 2.0 kernels, so they will only allow read-only
1901mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001902
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001903Fix bug where if /dev/null couldn't be opened (should never happen),
1904e2fsck would hang in a tight loop.
1905
1906Make e2fsck handle the case where /lost+found isn't a directory.
1907
1908E2fsck now uses mallinfo if it exists to get accurate statistics about
1909its memory usage.
1910
1911Fix bug in e2fsck where it wouldn't check to see if a disconnected
1912inode had any problems before connecting it to /lost+found.
1913
1914Add check to e2fsck so it makes sure that total number of inodes in
1915the filesystem is a sane number.
1916
1917Fix fencepost error when clearing an the end of the block bitmap which
1918caused the last block in the bitmap not to get cleared.
1919
1920Cleaned up a number of messages in e2fsck:
1921 * The message "Group's #'s copy of the group descriptor..."
1922 was fixed so that the correct number would be displayed.
1923 * Added missing space in the "disk write-protected" error messsage
1924 * Cleaned up the error message printed when a non-interactive
1925 e2fsck needs to abort a check because the filesystem
1926 appears to be mounted.
1927
1928Added a new command-line utility, uuidgen, which will create and print
1929a UUID.
1930
1931Make debugfs's icheck command more robust by checking to make sure an
1932inode has valid blocks before interarting over the inode's blocks.
1933
1934UUID generation now uses a random-based scheme whenever possible to
1935prevent potential privacy problems.
1936
1937Man pages for all of the UUID functions in the lirbary were added.
1938
1939Fixed bug in fsck so it won't coredump if a filesystem not in
1940/etc/fstab is given to it.
1941
1942Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
1943that most of the other mount utilities understands.
1944
1945Mke2fs will make a filesystem even if it appears mounted if the force
1946option is given.
1947
1948Dumpe2fs has new command-line options which allow a filesystem expert
1949to specify the superblock and blocksize when opening a filesystem.
1950This is mainly useful when examining the remains of a toasted
1951filesystem.
1952
1953The badblocks program has been updated to display correctly on disks
1954with large block numbers.
1955
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001956The badblocks program no longer gives spurious errors when errors
1957occur on non-block boundaries, which is common if the blocksize is
1958larger than 1k.
1959
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001960Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
1961MKE2FS_SYNC environment variable is set. This is to work around a VM
1962bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001963to trigger it even using a 2.2 kernel, but hopefully it will not be
1964needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001965
1966Fixed miscellaneous documentation and man pages.
1967
1968Programmer's notes:
1969-------------------
1970
1971Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
1972in e2fsck's pass1.c really should have been static.
1973
1974The return value of the uuid_compare() function was changed to make it
1975match with the convetions used by strcmp, memcmp, and Paul Leach's
1976UUID sample document.
1977
1978The "make depend" process has now been made more automated; it now
1979automatically word-wraps the dependencies, and only replaces source
1980Makefile.in if there has been a change in the dependencies. Also, a
1981top-level "make depend" now recurses through all the subdirectories
1982automatically.
1983
1984The Makefile in .../util has been changed so that subst is built using
1985the native C compiler during a cross-compilation, since the subst
1986program is only used during the build process. Also add an explicit
1987rule to build util/subst by cd'ing to the correct directory and
1988running Makefile.
1989
1990The man directories are defined in terms mandir, so that the configure
1991script can override the location of the manual pages.
1992
1993The config files have been updated to recognize new machine types for
1994both the i386 and alpha families.
1995
1996Fsck has been modified so that it will accurately create an
1997fsck_instance even when the noexecute flag is set. This allows for
1998accurate debugging of the fsck pass structure. Also, when the verbose
1999flag is given twice, fsck will print debugging information about when
2000fsck is waiting for jobs to finish.
2001
2002
Theodore Ts'o14790ed1999-01-12 23:32:52 +00002003E2fsprogs 1.14 (January 9, 1999)
2004================================
2005
2006Fix the fstab parsing code so that it can handle blank lines and
2007comment characters. Also, missing pass numbers need to be treated as
2008zero.
2009
2010Fixed a bug in e2fsck where under some circumstances (when e2fsck
2011needs to restart processing after fixing an egregious inconsistency)
2012it would try to access already freed memory.
2013
2014E2fsck now prints non-printable characters in directory entries and
2015pathnames using '^' and 'M-' notation.
2016
2017Fixed chattr so that it will ignore symbolic links when doing
2018recursive descent traversals. For both chattr and lsattr, no longer
2019print the version string unless the -V option is given.
2020
2021Allow the system administrator to directly specify the number of
2022inodes desired in the filesystem, for some special cases where this is
2023necessary.
2024
2025Fix portability problems so that e2fsprogs can be compiled under Linux
20261.2 systems and Solaris systems.
2027
2028Update the config.guess file with a more recent version that will
2029identify newer Linux platforms.
2030
2031Programmer's notes
2032------------------
2033
2034Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2035an inode number of zero is passed to them.
2036
Theodore Ts'o556ad131998-12-19 08:10:58 +00002037E2fsprogs 1.13 (December 15, 1998)
2038==================================
2039
2040Fixed a bug in debugfs where an error messages weren't getting printed
2041when the ext2 library routines to read inodes returned errors in the
2042stat, cmri and rm commands.
2043
2044Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2045provided, it won't create an inode table smaller than the minimum
2046number of inodes required for a proper ext2 filesystem.
2047
2048Fsck now parses the /etc/fstab file directly (instead of using
2049getmntent()), so that it can distinguish between a missing pass number
2050field and pass number field of zero. This caused problems for
2051diskless workstations where all of the filesystems in /etc/fstab have
2052an explicit pass number of zero, and fsck could not distinguish this
2053from a /etc/fstab file with missing pass numbers.
2054
2055E2fsck will create a /lost+found directory if there isn't one in the
2056filesystem, since it's safer to create the lost+found directory before
2057it's needed.
2058
2059Fixed e2fsck so that it would detect bogus immutable inodes which
2060happen to be sockets and FIFO files, and offer to clear them.
2061
2062If a filesystem has multiple reasons why it needs to be checked, and
2063one of the reasons is that it is uncleanly mounted, e2fsck will print
2064that as the reason why the filesystem is being checked.
2065
2066Cleaned up the output routines of mke2fs so that it doesn't overflow
2067an 80 column display when formating really big filesystems.
2068
2069Added a sanity check to e2fsck to make sure that file descriptors 0,
20701, 2 are open before opening the hard disk. This avoids a problem
2071where a broken program might exec e2fsck with those file descriptors
2072closed, which would cause disastrous results if the kernel returns a
2073file descriptor for the block device which is also used by FILE *
2074stdout.
2075
2076Fixed up the e2fsck progress reporting functions so that the values
2077reliably reach 100% at the completion of all of the e2fsck passes.
2078
2079Fixed minor documentation bugs in man pages and usage messages.
2080
2081Programmer's notes:
2082-------------------
2083
2084Fixed a number of lint warnings in the ext2fs library and potential
2085portability problems from other OS's header files that might define
2086CPP macros for names like "max" and "min".
2087
2088ext2fs_badblocks_list_add() has been made more efficient when it needs
2089to grow the bad blocks list.
2090
2091Fixed a bug in e2fsck which caused it to dereference a freed pointer
2092just before exiting.
2093
2094Fixed the substition process for generating the mk_cmds and compile_et
2095scripts so that they will work outside of the build tree.
2096
2097Add sanity check to e2fsck so that if an internal routine
2098(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2099and causing a core dump. This should never happen, but...
2100
Theodore Ts'oa5696711998-07-09 05:38:07 +00002101E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002102==================================
2103
2104E2fsprogs now works with glibc (at least with the version shipped wtih
2105RedHat 5.0). The ext2fs_llseek() function should now work even with
2106i386 ELF shared libraries and if llseek() is not present. We also
2107explicitly do a configure test to see if (a) llseek is in libc, and
2108(b) if llseek is declared in the system header files. (See standard
2109complaints about libc developers don't understand the concept of
2110compatibility with previous versions of libc.)
2111
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002112The ext2fs library now writes out the block group number in each of
2113the superblock copies. This makes it easier to automatically
2114determine the starting block group of the filesystem when the block
2115group information is trashed.
2116
2117Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002118which means that e2fsprogs will ignore the high 8 bits of the
2119directory entry's name_len field, so that it can be used for other
2120purposes.
2121
2122Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2123E2fsprogs will now support filesystems with 64-bit sized files.
2124
2125Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2126
Theodore Ts'o21d53851998-02-21 03:14:50 +00002127Added new program "e2label", contributed by Andries Brouwer. E2label
2128provides an easy-to-use interface to modify the filesystem label.
2129
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002130Fixed bug so that lsattr -v works instead of producing a core dump.
2131
Theodore Ts'o21d53851998-02-21 03:14:50 +00002132Fixed a minor bug in mke2fs so that all groups with bad superblock
2133backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002134
2135Mke2fs will check the size of the device, and if the user specifies a
2136filesystem size larger than the apparent size of the device it will
2137print a warning message and ask if the user wants to proceed.
2138
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002139E2fsck has a new option -C, which sends completion information to the
2140specified file descriptor. For the most part, this is intended for
2141programs to use, although -C 0 will print a spinning character to the
2142stdout device, which may be useful for users who want to see something
2143happening while e2fsck goes about its business.
2144
Theodore Ts'o21d53851998-02-21 03:14:50 +00002145Fixed a bug in e2fsck which could cause a core dump when it needs to
2146expand the /lost+found directory, and sometimes the bitmaps haven't
2147been merged in. Also fixed a related bug where ext2fs_write_dir_block
2148was used to write out a non-directory block. (Which would be bad on a
2149non-Intel platform with byte swapping going on.)
2150
2151Fixed bug in e2fsck where it would print a "programming error" message
2152instead of correctly identifying where a bad block was in used when
2153the bad block was in a non-primary superblock or block group
2154descriptor. Also fixed a related bug when sparse superblocks are in
2155use and there is a bad block where a superblock or block group
2156descriptor would have been in a group that doesn't include a
2157superblock.
2158
2159Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2160the block group descriptor table is corrupt, it was possible to try to
2161allocate a huge array, fail, and then abort e2fsck.
2162ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2163and subsitutes reasonable values if the descriptors are obviously bogus.
2164
2165If e2fsck finds a device file which has the immutable flag set and the
2166i_blocks beyond the normal device number are non-zero, e2fsck will
2167offer to remove it, since it's probably caused by garbage in the inode
2168table.
2169
2170When opening a filesystem, e2fsck specially checks for the EROFS error
2171code, and prints a specific error message to the user which is more
2172user friendly.
2173
2174If the filesystem revision is too high, change the e2fsck to print
2175that this is either because e2fsck is out of date, or because the
2176superblock is corrupt.
2177
2178E2fsck now checks for directories that have duplicate '.' and '..'
2179entries, and fixes this corruption.
2180
2181E2fsck no longer forces a sync of the filesystem (with attendant sleep
2182calls) at all times. The ext2fs_flush() function now performs a sync
2183only if it needed to write data blocks to disk.
2184
2185Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2186certain errors would not be properly reported.
2187
2188Updated and expanded a few points in the man pages which users
2189complained wheren't explicit enough.
2190
2191Added special case byte-swapping code if compiling on the PowerPC, to
2192accomodate the strange big-endian variant of the ext2 filesystem that
2193was previously used on the PowerPC port.
2194
2195
2196Programmer's notes:
2197-------------------
2198
2199Removed C++ keywords from the ext2fs libraries so that it could be
2200compiled with C++.
2201
2202E2fsck's internal organization has now been massively reorganized so
2203that pass*.c don't have any printf statements. Instead, all problems
2204are reported through the fix_problem() abstraction interface. E2fsck
2205has also been revamped so that it can be called as a library from a
2206application.
2207
2208Added new fileio primitives in libext2fs for reading and writing
2209files on an unmounted ext2 filesystem. This interface is now used by
2210debugfs.
2211
2212Added a new libext2fs function for mapping logical block numbers of
2213a file to a physical block number.
2214
2215Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2216a block, zeros it, and updates the filesystem accounting records
2217appropriately.
2218
2219Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2220sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2221
2222The libext2fs functions now use a set of memory allocation wrapper
2223functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2224instead of malloc, free, and resize. This makes it easier for us to
2225be ported to strange environments where malloc, et. al. aren't
2226necessarily available.
2227
2228Change the libext2fs fucntion to return ext2-specific error codes
2229(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2230and depending on the existence of system error codes (such as EEXIST
2231and ENOENT).
2232
2233Renamed io.h to ext2_io.h to avoid collision with other OS's header
2234files.
2235
2236Add protection against ext2_io.h and ext2fs.h being included multiple
2237times.
2238
2239The types used for memory lengths, etc. have been made more portable.
2240In generla, the code has been made 16-bit safe. Added Mark
2241Habersack's contributed DOS disk i/o routines.
2242
2243Miscellaneous portability fixes, including not depending on char's
2244being signed.
2245
2246The io_channel structure has a new element, app_data, which is
2247initialized by the ext2fs routines to contain a copy of the filesystem
2248handle.
2249
2250ext2fs_check_directory()'s callback function may now return the error
2251EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2252really do the checking, despite the presence of the callback function.
2253
2254
Theodore Ts'obc210071997-06-17 05:41:36 +00002255E2fsprosg 1.11 (June 17, 1997)
2256==============================
2257
2258Fixed e2fsck to detect (previously ignored) conflicts between the
2259superblock or block group descriptors and block bitmaps, inode
2260bitmaps, and inode tables.
2261
2262Fixed bug in e2fsck so that when the message printed out when a block
2263or inode bitmap conflicts with other data, it has the correct group
2264number.
2265
2266Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2267to badblocks. This meant that not all of the filesystem was being
2268tested for bad blocks!
2269
2270Fixed an array boundary overrun case which cropped up in
2271ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2272-b 4096".
2273
2274Adjusted the number of columns printed by mke2fs when displaying the
2275superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00002276really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00002277
2278Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2279dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2280fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2281
2282Programmer's notes:
2283-------------------
2284
2285Fixed install rule in lib/ss so that ss_err.h is actually getting
2286installed.
2287
2288Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2289bassed back to the caller.
2290
2291Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2292setting the current inode number (which meant this function wasn't
2293working at all).
2294
2295Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2296blocks in the bitmap when increasing the size of the bitmap.
2297
2298Changed the initial number of blocks allocated by ext2fs_init_dblist()
2299to be more realistic.
2300
2301Added a new function ext2fs_allocate_group_table, which sets up the
2302group descriptor information (and allocates inode and block bitmaps,
2303and inode tables for a particular group). The function was created by
2304factoring out code form ext2fs_allocate_tables().
2305
2306Added a new function ext2fs_move_blocks which takes a bitmap of the
2307blocks to be moved, and moves them to another location on the
2308boardboard.
2309
2310Make the unix_io channel's io_channel_flush implementation calls sync()
2311to to flush the kernel buffers to disk.
2312
2313Added a new function ext2fs_dblist_count returns the number of
2314directory blocks in dblist.
2315
2316
Theodore Ts'oae851481997-04-29 18:13:24 +00002317E2fsprogs 1.10 (April 24, 1997)
2318===============================
2319
2320Mke2fs once again defaults to creating revision #0 filesystems, since
2321people were complaining about breaking compatibility with 1.2 kernels.
2322Warning messages were added to the mke2fs and tune2fs man pages that
2323the sparse superblock option isn't supported by most kernels yet (1.2
2324and 2.0 both don't support parse superblocks.)
2325
2326Added new flag to mke2fs, -R <raid options>, which allows the user to
2327tell mke2fs about the RAID configuration of the filesystem. Currently
2328the only supported raid option is "stride" which specifies the width
2329of the RAID stripe.
2330
2331Fixed bug in e2fsck where pass1b would bomb out if there were any
2332blocks marked bad in the inode table.
2333
2334Fixed rare bug in mke2fs where if the user had a very unlucky number
2335of blocks in a filesystem (probability less than .002) the resulting
2336filesystem would be corrupt in the last block group.
2337
2338Fixed bug where if e2fsck tried to allocate a block to fix a
2339filesystem corruption problem and the filesystem had no free blocks,
2340ext2fs_new_block() would loop forever.
2341
2342The configure script now checks explicitly to see if "-static" works,
2343since that can't be assumed to be true --- RedHat doesn't install
2344libc-static by default.
2345
2346Fixed bug in libext2's block iterator functions where under some
2347cirmcustances, file with holes would cause the bcount parameter to the
2348callback function to be incorrect. This bug didn't affect any of
2349e2fsprogs programs, but it was discovered by Paul Mackerras, the
2350author of the PPC boot loader.
2351
2352Removed use of static variables to store the inode cache in libext2fs.
2353This caused problems if more than one filesystem was accessed via
2354libext2fs (static variables in libraries are generally a bad idea).
2355Again, this didn't affect e2fsprogs programs, but it was discovered by
2356Paul Mackerras.
2357
2358Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
2359will compile cleanly with 1.2.13 kernels (even with a.out shared
2360libraries!)
2361
2362Programmer's notes:
2363-------------------
2364
2365Added new functions to duplicate an ext2 filesystem handle, and its
2366associated substructure. New functions: ext2fs_dup_handle(),
2367ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
2368Other structures, such as the io_channel and the inode_cache, now have
2369a ref count so that they only get freed when they are no longer used
2370by any filesystem handle. (These functions were added as part of the
2371development effort for an ext2 resizer).
2372
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00002373E2fsprogs 1.09 (April 14, 1997)
2374===============================
2375
2376Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
2377accidentally introduced in the 1.08 release. The overhead calculation
2378was accidentally removed, which caused ext2fs_initialize() to not
2379notice when the filesystem size needed to be adjusted down because
2380there wasn't enough space in the last block group.
2381
2382Fixed bug in version parsing library routine; it was always parsing
2383the library version string, instead of using the passed-in string.
2384
2385Clarified chattr man page.
2386
Theodore Ts'o24757fa1997-04-29 17:39:27 +00002387E2fsprogs 1.08 (April 10, 1997)
2388===============================
2389
2390E2fsck 1.07 was very slow when checking very large filesystems with a
2391lot of files that had hard links (i.e., news spools). This was fixed
2392by seriously revamping the icount abstraction. Added a formal test
2393suite for the icount abstraction.
2394
2395Debugfs now has a "-l" option to the "ls" command, which lists the
2396inode number, permissions, owner, group, size, and name of the files
2397in the directory.
2398
2399Fix a bug in e2fsck where when a directory had its blocks moved to
2400another location during the pass 1b processing, the directory block
2401list wasn't updated, so pass 2 wouldn't check (and correct) the
2402correct directory block.
2403
2404E2fsck will now treat inodes which contain blocks which are claimed by
2405the filesystem metadata by treating them as multiply claimed blocks.
2406This way, the data in those blocks can be copied to a new block during
2407the pass 1b--1d processing.
2408
2409E2fsck will attempt to determine the correct superblock number and
2410display it in the diagnostic and warning messages if possible.
2411
2412Add support for a new (incompatible) feature, "sparse_super". This
2413feature reduces the number of blocks which contain copies of backup
2414superblocks and block group descriptors. (It is only an incompatible
2415feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
2416support a new -s option; e2fsck will recognize filesystems built with
2417this feature turned on.
2418
2419E2fsck now checks the library to make sure is the correct version,
2420using new library functions. (This helps to diagnose incorrectly
2421installed e2fsprogs distributions.)
2422
2423Dumpe2fs now prints more information; its now prints the the
2424filesystem revision number, the filesystem sparse_super feature (if
2425present), the block ranges for each block group, and the offset from
2426the beginning of the block group.
2427
2428Mke2fs now distributes the inode and block bitmap blok so that the
2429won't be concentrated in one or two disks in RAID/striping setups.
2430Also, if the user chooses a 2k or 4k block group, mke2fs will try to
2431choose the largest blocks per group that be chosen. (For 2k blocks,
2432you can have up to 16384 blocks/group; for 4k blocks, you can have up
2433to 32768 blocks/group.) Previously mke2fs would not allow
2434specification of more than 8192 blocks per group, even if you were
2435using a 2k or 4k block group.
2436
2437Programmer's notes:
2438-------------------
2439
2440Added a new function ext2fs_create_icount2() which takes a "hint"
2441argument. This hint argument presets the icount array with the list
2442of inodes which actually need to be in the icount array. This really
2443helps to speed up e2fsck.
2444
2445Added a new function ext2fs_icount_validate() which checks the rep
2446invariant for the icount structure. This is used mostly for testing.
2447
2448The error mesasage given when a bad inode number is passed to
2449test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
2450EXT2FS_UNMARK_ERROR).
2451
2452Added a new function ext2fs_set_dir_block which sets the block of a
2453dblist entry, given the directory inode and blockcnt.
2454
2455Added a new function ext2fs_get_library_version() which returns the
2456current library version, and ext2fs_parse_version_string() which
2457returns a version number based on a e2fsprogs version string.
2458
2459The icount functions will return EINVAL if the passed in inode number
2460is out of bounds.
2461
Theodore Ts'o21c84b71997-04-29 16:15:03 +00002462E2fsprogs 1.07 (March 9, 1997)
2463==============================
2464
2465E2fsck is now uses much less memory when checking really large
2466filesystems (or rather, filesystems with a large number of inodes).
2467Previously a filesystem with 1 million inodes required 4 megabytes of
2468memory to store inode count statistics; that storage requirement has
2469now been reduced to roughly half a megabyte.
2470
2471E2fsck can now properly deal with bad blocks appearing inside the
2472inode table. Instead of trying to relocate the inode table (which
2473often failed because there wasn't enough space), the inodes in the bad
2474block are marked as in use.
2475
2476E2fsck will automatically try to use the backup superblocks if the
2477primary superblocks have a bad magic number or have missing meta-data
2478blocks (or meta-data blocks which are out of range).
2479
2480E2fsck's pass 3 has been made more efficient; most noticeable on
2481filesystems with a very large number of directories.
2482
2483Completely revamped e2fsck's system of printing problem reports. It
2484is now table driven, to make them more easily customizeable and
2485extendable. Error messages which can be printed out during preen mode
2486are now one line long.
2487
2488Fixed e2fsck's filesystem swapping code so that it won't try to swap
2489fast symbolic links or deleted files.
2490
2491Fixed e2fsck core dumping when fixing a filesystem which has no
2492directories (not even a root directory).
2493
2494Added a check to e2fsck to make sure that the length of every
2495directory entry is a multiple of 4 (since the kernel complains if it
2496isn't).
2497
2498Added a check to e2fsck to make sure that a directory entry isn't a
2499link to the root directory, since that isn't allowed.
2500
2501Added a check to e2fsk to now make sure the '.' and '..' directory
2502entries are null terminated, since the 2.0 kernel requires it.
2503
2504Added check to write_bitmaps() to make sure the superblock doesn't get
2505trashed if the inode or block bitmap is marked as being block zero.
2506
2507Added checking of the new feature set fields in the superblock, to
2508avoid dealing with new filesystem features that this package wasn't
2509set up to handle.
2510
2511Fixed a fencepost error in ext2fs_new_block() which would occasionally
2512try to allocate a block beyond the end of a filesystem.
2513
2514When the UUID library picks a random IEEE 802 address (because it
2515can't find one from a network card), it sets the multicast bit, to
2516avoid conflicting with a legitimate IEEE 802 address.
2517
2518Mke2fs now sets the root directory's owner to be the real uid of the
2519user running mke2fs. If the real uid is non-zero, it also sets
2520the group ownership of the root directory to be the real group-id of
2521the user running mke2fs.
2522
2523Mke2fs now has more intelligent error checking when it is given a
2524non-existent device.
2525
2526When badblocks is given the -vv option, it now updates the block that
2527it is currently testing on every block.
2528
2529Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
2530currently correctly if PATH wasn't already set.
2531
2532Shared libraries now built with dependencies. This allows the shared
2533library files to be used with dlopen(); it also makes the transition
2534to libc 6 easier, since ld.so can tell which libc a particular shared
2535library expects to use.
2536
2537Programmer's notes:
2538-------------------
2539
2540Added new abstraction (defined in dblist.c) for maintaining a list of
2541blocks which belongs to directories. This is used in e2fsck and other
2542programs which need to iterate over all directories.
2543
2544Added new functions which test to see if a contiguous range of blocks
2545(or inodes) are available. (ext2fs_*_bitmap_range).
2546
2547Added new function (ext2_inode_has_valid_blocks) which returns true if
2548an inode has valid blocks. (moved from e2fsck code).
2549
2550Added new function (ext2fs_allocate_tables) which allocates the
2551meta-data blocks as part of initializing a filesystem. (moved from
2552mke2fs code).
2553
2554Added a new I/O manager for testing purposes. It will either allow a
2555program to intercept I/O requests, or print debugging messages to
2556trace the activity of a program using the I/O manager.
2557
2558The badblocks_list functions now store the bad blocks in a sorted
2559order, and use a binary search to speed up badblocks_list_test.
2560
2561The inode scan function ext2fs_get_next_inode() may now return a soft
2562error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
2563those cases where part of an inode table is missing or there is a bad
2564block in the inode table.
2565
2566Added a new function (ext2fs_block_iterate2) which adds new arguments to
2567the callback function to return a pointer (block and offset) to the
2568reference of the block.
2569
2570Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
2571application to jump to a particular block group while doing an inode
2572scan.
2573
2574The badblocks list functions were renamed from badblocks_* to
2575ext2fs_badblocks_*. Backwards compatibility functions are available
2576for now, but programs should be modified to use the new interface.
2577
2578Some of the library functions were reorganized into separate files to
2579reduce the size of some programs which statically link against the
2580ext2 library.
2581
2582Put in some miscellaneous fixes for the Alpha platform.

2585E2fsprogs 1.06 (October 7, 1996)
2586================================
2587
2588Fixed serious bug in e2fsck: if the block descriptors are bad, don't
2589smash the backup copies in ext2fs_close(). (The problem was that when
2590e2fsck -p discovered the problem, while it was closing the filesystem
2591and exiting, it was also blowing away the backup superblocks on the
2592disk, which was less than friendly.) We now make it the case that we
2593only write out the backup superblock and the back block descriptors if
2594the filesystem is completely free from problems.
2595
2596Fixed a bug in block_interate in the lib/ext2fs library which caused
2597e2fsck to fail on GNU Hurd-created filesystems.
2598
2599Add support for Linux/FT's bootloader, which actually uses
2600EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
2601to clear the inode.
2602
2603Add support for the "A" (no atime update) attribute. (Note: this
2604attribute is not yet in production kernels.)
2605
2606The test suite is not automatically run when doing a "make all" from
2607the top level directory. Users should manually run "make check" if
2608they wish to run the test suite.
2609
2610Upon a preenhalt(), make the printed message more explicit that
2611running e2fsck "MANAULLY" means without the -p or -a options.
2612
2613In e2fsck, if a disconnected inode is zero-length, offer to clear it
2614instead of offering to connect it to lost+found.
2615
2616In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2617e2fsck to be run over it, change e2fsck to explicitly display this
2618fact.
2619
2620For dumpe2fs and e2fsck, cause the -V option to print out which
2621version of the ext2fs library is actually getting used. (This will
2622help detect mismatches of using a 1.06 utility with a 1.05 library,
2623etc.)
2624
2625Programmers' notes:
2626-------------------
2627
2628EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2629the naming convention.
2630
2631In ext2fs_initialize(), make sure the description for the inode bitmap
2632is correctly initialize.
2633
2634Fixed minor type typo in ext2fs_allocate_generic_bitmap();
2635
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002636E2fsprogs 1.05 (September 7, 1996)
2637==================================
2638
2639Add support for new fields in the ext2 superblock --- volume name,
2640volume UUID, and last mounted field. Dumpe2fs displays these fields,
2641tune2fs and mke2fs allows you to set them. E2fsck will automatically
2642generate a UUID for those volumes that don't have them.
2643
2644Put in support for e2fsck to recognize HURD specific ext2 features ---
2645most notably, the translator block. The e2fsprogs tools will now use
2646the creator_os field in the superblock to correctly handle different
2647OS-specific variants of the ext2 filesystem.
2648
2649E2fsck now fixes inodes which have a the deletion time set, but which
2650have a non-zero i_link_count field by offering to clear the deletion
2651time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2652ext2 kernel behavior) and offered to unlink the file.
2653
2654If e2fsck sets the clean bit, but nothing else, set the exit code
2655FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2656set the filesystem valid bit when it was previously cleared. :-) This
2657was needed to make the HURD fsck driver happy.
2658
2659If the user refuses to attach an unattached inode, e2fsck will no
2660longer set the inode's link count. Otherwise, the inode would end up
2661getting marked as unused, which might cause loss of data later.
2662
2663Make the message issued by e2fsck when the superblock is corrupt less
2664confusing for users. It now mentions that another reason for the
2665"corrupt superblock" message might be that the partition might not be
2666an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2667
2668Make the libext2 library more robuest so that e2fsck won't coredump on
2669an illegal superblock where the blocksize is zero. (f_crashdisk is
2670the test case).
2671
2672By default, create filesystems where the default checkinterval is 6
2673months (180 days). Linux servers can be robust enough that 20 reboots
2674can be a long, long time.
2675
2676Added configure flag --enable-old-bitops, which forces the bitops to
2677use the old (native) bitmask operations. By default on the sparc
2678platform, the standard ext2 bit ordering is now used.
2679
2680Added a new feature to e2fsck to byte-swap filesystems; this can be
2681used to convert old m68k filesystems to use the standard byte-order
2682storage for the superblock, inodes, and directory blocks. This
2683function is invoked by using the '-s' option to e2fsck.
2684
2685Debugfs's "dump" command has been enhanced so that it writes out the
2686exact size of the file so that the nulls at the end of the file are
2687eliminated. The command also accept a new "-p" option which will
2688attempt preserve to preserve the ownernship, permissions, and
2689file modification/access times.
2690
2691Debugfs has two new options, -f and -R. The -R option allows the user
2692to execute a single debugfs command from the command line. The -f
2693option allows the user to specify a "command file" containing debugfs
2694commands which will get executed.
2695
2696Dumpe2fs now pretty prints the check interval, instead of just
2697printing the check interval as a number of seconds.
2698
2699Fix bugs in debugfs: the params command when no filesystem is opened
2700no longer causes a core dump. It is now possible to unlink a file
2701when a pathame containing a '/' is specified.
2702
2703Tune2fs has a new -C option which sets the number of times the
2704filesystem has been mounted.
2705
2706Fix the chattr '-v' option so that it actually works. Chattr was
2707being buggy about the -v option parsing.
2708
2709Programmers' notes:
2710-------------------
2711
2712The directory lib/uuid contains a set of library routines to generate
2713DCE compatible UUIDs.
2714
2715Extended ext2fs_namei() to handle symbolic links. Added new function
2716ext2fs_nami_follow() which will follow last symbolic link in the case
2717where the pathname points to a sym link.
2718
2719The ext2fs_block_iterate function will now return the HURD translator
2720block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2721iterator to return data blocks only. The ext2fs.h file now defines
2722constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2723BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2724count field of the iterator callback function.
2725
2726The test script driver now takes an optional second argument, which is
2727the test case to be run. This allows you to run a test case without
2728needing to run the entire test suite.
2729
2730On Linux ELF systems, install the .so files in the correct places
2731(/usr/lib). The .so files must be stored in the same directory as the
2732.a files.
2733
2734Fixed miscellaneous HURD compilation issues with header file being
2735included in the right order.
2736
2737Fixed debugfs so that it resets optind to zero, not one, since setting
2738optind to zero is more correct.
2739

Theodore Ts'oa4d09611997-04-29 14:28:00 +00002741E2fsprogs 1.04 (May 16, 1996)
2742=============================
2743
2744First "official" (1.03 was a limited release only) to support building
2745e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2746kernels).
2747
2748This package includes a RPM specs file, that it can be built using the
2749RedHat Package Manager.
2750
2751E2fsck now prints a hint that if there are lots of incorrectly located
2752inode bitmaps, block bitmaps, and inode table blocks, the user might
2753want to try using e2fsck -b 8193 first, to see if that fares any
2754better.
2755
2756For ext2 filesystem written with the hurd, debugfs will now print out
2757the translator field when printing an inode structure.
2758
2759Lots of miscellaneous linking/installation cleanups:
2760
2761 Libraries are now linked using a relative pathname, instead of
2762 relying on -L working correct. It doesn't, in many cases, including
2763 current versions of GNU ld. This guarantees that the build tree is
2764 linking with the right libraries, instead of the ones installed in
2765 /usr/lib.
2766
2767 Header files, man pages, and the et/ss shell scripts are now
2768 generated using a custom substitution script, instead of relying on
2769 the configure script. This prevents needless recompilation of
2770 files; in addition, the custom substitution script is much faster.
2771
2772 e2fsck may now be linked dynamically, by using the
2773 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2774 since it increases e2fsck's dependence on other files, but some
2775 people need to save disk space, and other critical programs on their
2776 systems were being linked dynamically anyway.
2777
2778 Programs such as fsck which didn't need to be linked against
2779 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2780 only link against libraries they actually need. Otherwise, those
2781 programs would require the presense of libraries that otherwise
2782 could be removed from a rescuse diskette.
2783
2784 The ss include files are now installed correctly so they can
2785 actually be used by another package.
2786
2787 If the profiling libraries are built, they are now installed on a
2788 "make install-libs".
2789

Theodore Ts'o7f88b041997-04-26 14:48:50 +00002791E2fsprogs 1.03 (March 27, 1996)
2792===============================
2793
2794Change the m68k bit numbering for bitmasks to match the bit numbering
2795used by all other ext2 implementations. (This change was requested by
2796the m68k kernel development team.)
2797
2798Support (in-development) filesystem format revision which supports
2799(among other things) dynamically sized inodes.
2800
2801Fixed a bug in the ext2 library so that an intelligent error is
2802returned if mke2fs is run with a ridiculously small number of blocks
2803for a partition.
2804
2805Fixed a bug in the ext2 library which required that the device be
2806openable in read/write mode in order to determine its size. This
2807caused e2fsck -n to require read/write access when it was not
2808previously necessary.
2809
2810Fixed a bug in e2fsck which casued it to occasionally fail the test
2811suite depending on which version of the floating point library it was
2812using.
2813
2814Fixed a bug in e2fsck so that it now halts with a fatal error when
2815certain superblock consistency checks fail. Previously it continued
2816running e2fsck, with some potential confusing/damaging consequences.
2817
2818Added new flag to fsck which allows the root to be checked in parallel
2819with other filesytems. This is not the safest thing in the world to
2820do, but some system administrators really wanted it.
2821
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002822Fixed -Wall flames in lib/ss.
2823
Theodore Ts'o74becf31997-04-26 14:37:06 +00002824
2825E2fsprogs 1.02 (January 16, 1996)
2826=================================
2827
2828Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
2829
2830Change e2fsck to print statistics of how many non-contiguous files are
2831on the system. Note that a file which is larger than 8k blocks, it is
2832guaranteed to be non-contiguous.
2833
2834In mke2fs, print a warning message if a user tries to format a whole
2835disk (/dev/hda versus /dev/hda1). If a user really wants to format a
2836whole disk, the -F (force) option forces mke2fs to format a whole disk
2837as a filesytem.
2838
2839Fix a bug in fsck where in some cases it might start checking
2840partitions in the next pass before it finishes checking partitions in
2841the current pass. This still won't cause two partitions on the same
2842disk will be checked, so it's rarely a problem in real life.
2843
2844Patch lsattr so that it won't hang when checking a named pipe.
2845
2846Minor compilation fixes:
2847 * Fix the order of libraries that were linked in debugfs.
2848 * Allow the sources to be compiled with -ansi turned on.
