Theodore Ts'o48301122004-09-19 08:23:41 -04001e2fsprogs 1.36-WIP (September 19, 2004)
2=======================================
3
4Fixed two potential ordering constraint problems in e2fsck which might
5cause the filesystem to be corrupted if e2fsck is interrupted during a
6(extremely narrow) race window. Thanks to Junfeng Yang from the
7Stanford Metacompilation group for pointing this out.
8
9Fixed bug in e2fsck where it would not accurately detect whether or
10not the system is running on adaptor if the ACPI device representing
11the AC adapter didn't correspond to the what was used on IBM
12Thinkpads.
13
14Change e2fsck to accept directories greater than 32MB.
15
16Fix e2fsck so that a checkinterval of zero disables a time-based check
17of the filesystem.
18
19Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
20to the PAGER environment variable. (Addresses Debian Bug #239547)
21
22Tune2fs will not mark rewrite the superblock if the feature bitmasks
23are not modified.
24
25The debugfs program will set the filetype information when creating a
26link.
27
28Add debugfs -d option to use a separate source of data blocks when
29reading from an e2image file.
30
31Add e2image -I option which allows the e2image metadata to be
32installed into a filesystem.
33
34Fixed bug in the badblocks program which caused "done" to always
35appear in english even when a translation was available. (Addresses
36Debian Bug #252836)
37
38The blkid program has a new option -o which controls the output format
39of the blkid program; this is makes blkid more convenient to use in
40shell scripts.
41
42Fix a minor bug in uuid library, which was not using the full 14 bits
43of clock sequence when generating UUID's.
44
45Fix a Y8.8888K problem in the uuid library.
46
47Logsave now creates a new session id for itself to avoid getting
48killed by init whan transitioning between init levels.
49
50Change the licensing of the UUID library to be the 3-clause BSD-style
51license; this allows Apple to use the uuid library in Darwin.
52
53Add ocfs and ocfs2 probe support into the blkid library.
54
55Fix a memory and file descriptor leak in the blkid library.
56
57The blkid library will revalidate the device if the system time is
58earlier than last verification time of the device, since that
59indicates that the system time is probably nottrustworthy.
60
61The blkid library will override the default location of the blkid.tab
62file by the BLKID_FILE environment variable, if it is available.
63
64Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
65
66Add various portability fixes for lame new versions of glibc, Darwin
67and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
68Bugs #239934, #264630, #269044, #255589)
69
70Updated and clarified various man pages. (Addresses Debian Bugs #236383,
71 #241940, #238741, #242995, #256669, #268148, #256760)
72
73Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
74
75Update the rpm spec files so that it works better with Fedora core 2
76and RH9.
77
78Fixed various Debian packaging issues (see debian/changelog). In
79particular, fixed the Debian initrd scripts. (#241183, #248050,
80#253595, #247775)
81
82
83Programmer's notes:
84-------------------
85
86Fixed various compiler warnings.
87
88The uuid library now has new functions uuid_unparse_upper() and
89uuid_unparse_lower() which forces the case of the hex digits to be
90upper case, or lower case.
91
92The build process has been speeded up by enhancing the subst program
93to update the modtime on the generated files even when the generated
94file hasn't changed.
95
96The uuid library now uses C99 stdint.h types instead of custom types.
97
98Updated config.guess and config.sub with newer versions from the FSF.
99
100Removed out of date .cvsignore files from the source distribution.
101
102Fix build of mke2fs.static.
103
104The test_io mechanism can now abort after n reads or writes to a
105particular block. The block is specified by TEST_IO_BLOCK environment
106variable, and the read/write count by the TEST_IO_READ_ABORT and
107TEST_IO_WRITE_ABORT environment variables. The block data is now only
108dumped if the 0x10 bit is set in TEST_IO_FLAGS.
109
110UUID_DEFINE() in the uuid library now creates a static variable, with
111__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
112be used in header files.
113
114
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500115E2fsprogs 1.35 (February 28, 2004)
116==================================
117
Theodore Ts'o48301122004-09-19 08:23:41 -0400118E2fsck has a new -k option, which in conjunction with the -c options,
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500119preserves the existing badblocks list.
120
Theodore Ts'o48301122004-09-19 08:23:41 -0400121Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500122
123E2fsprogs will now deal correctly with symlinks that contain
124extended attribute information, which can be created using SE Linux.
125(Addresses Debian Bug #232328)
126
127Remove a double longjump into an invalid stack frame bug in e2fsck.
128(This was during an abort sequence, which normally worked on Linux and
129caused a core dump on other operating systems.)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500130
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500131Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
132(the NLS library will replace "" with the .po header information).
133
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500134Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
135dump due to a division by zero error. (Addresses Debian bug #207082)
136
Theodore Ts'o151a7162003-12-26 14:04:33 -0500137Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
138when reconnecting a directory requires creating a lost+found
139directory. (Addresses Debian bug #219640).
140
141Fixed a bug where e2fsck would bomb out if a journal needed to be
142replayed when using an alternate superblock.
143
Theodore Ts'o48301122004-09-19 08:23:41 -0400144E2fsck will give an extra grace period before actually forcing a check
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500145if the laptop is running on battery. The next time fsck runs while
146the system is on the AC mains, or after the grace period is exceeded,
147the filesystem will be checked. (Addresses Debian bug #205177)
148
149E2fsck will inform the user when there are 5 or fewer mounts before a
150filesystem check will be forced. (Addresses Debian bug #157194)
151
152Fix e2fsck's handling of corrupted indirect blocks in the bad block.
153We now correctly handle the case where there is an overlap between a
154block group descriptor or a superblock and a bad block indirect block.
155In the case where the indirect block is corrupted, we now suggest
156"e2fsck -c".
157
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500158Fix byte swap bugs in e2fsck that caused the journal backup location
159in the superblock and symlinks created by SE Linux to be cleared
160by e2fsck on big-endian machines. (Addresses Debian bug #228723)
161
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500162E2fsck -c now replaces the current list of bad blocks with the ones
163found by badblocks.
164
165Fix bugs in e2fsck and tune2fs which could cause a core dump if a
166non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
167
168Fix a potential bug in e2fsck which could cause it to core dump when
169trying to print the location of the backup superblock.
170
171Protect against a potential core dump in e2fsck when printing a
172message about backup superblocks.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400173
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400174Add support for backing up the journal inode location in the
175superblock. E2fsck will automatically save the journal information in
176the superblock if it is not there already, and will use it if the
177journal inode appears to be corrupted. ext2fs_add_journal_inode()
178will also save the backup information, so that new filesystems created
179by mke2fs and filesystems that have journals added via tune2fs will
180also have journal location written to the superblock as well.
181Debugfs's logdump command has been enhanced so that it can use the
182journal information in the superblock.
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500183
184E2fsck will now update all superblocks when moving the journal inode.
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400185
186Shrink the size of the e2fsck executable by moving some initialized
187variables to the BSS segment.
188
189E2fsck will avoid printing the ^A and ^B characters which bracket the
190progress bar when stdout and stdin are a tty device instead of a pipe
191to another program. (Addresses Debian bug #204137)
192
Theodore Ts'o151a7162003-12-26 14:04:33 -0500193Debugfs's mkdir command will automatically expand the directory if
194necessary. (Addresses Debian Bug: #217892)
195
196Fixed a bug in debugfs so that copying a file from /dev/null uses the
197correct mode bits. (Addresses Debian Bug: #217456)
198
199If the environment variables DEBUFS_PAGER and PAGER are not set,
200debugfs now searches for the appropriate pager to use, beginning with
Theodore Ts'o2b5ddd72004-01-24 18:54:41 -0500201/usr/bin/pager, and then falling back to 'more' and 'less'.
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500202(Addresses Debian bug #221977)
203
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500204Debugfs will now support 2.6 device numbers where the major or minor
205number may be larger than 255. (Addresses Sourceforge bug #865289)
206
Theodore Ts'o48301122004-09-19 08:23:41 -0400207Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
208
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500209Chattr now stops processing options when it sees '--'. (Addresses
210Debian bug #225188)
Theodore Ts'o151a7162003-12-26 14:04:33 -0500211
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400212Fix regression tests so they work correctly when e2fsprogs is compiled
213with configure --disable-htree.
214
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500215Fix bug in uuid library when there is no network card and the library
216is generating a time-based uuid. The random MAC address was not
217correctly generated to be a multicast address.
218
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400219Add compile_et extensions from Heimdall that were missed the first time
Theodore Ts'o48301122004-09-19 08:23:41 -0400220around.
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400221
222Fix bug in badblocks when using O_DIRECT; we need to make sure that
223we're reading from an offset which is page aligned. For read-only and
224read-write tests, we try to recover after an error so that we can
225continue reading on page-aligned boundaries. (Addresses Debian Bug
226#203713)
227
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500228Badblocks now checks 64 blocks at a time instead of 16. (Addresses
229Debian bug #232240)
230
Theodore Ts'o151a7162003-12-26 14:04:33 -0500231Updated and clarified various man pages. (Addresses Debian Bug
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500232#206845, #222606, #214920, #232406)
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500233
Theodore Ts'o151a7162003-12-26 14:04:33 -0500234Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400235
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400236Fixed various Debian packaging issues (see debian/changelog).
237
238Programmer's notes:
239-------------------
240
Theodore Ts'ob70b1162004-02-28 10:52:35 -0500241Fixed a build problem so that e2fsprogs would compile with the
242--enable-profile option to configure selected. (Addresses Sourceforge
243bug #811408)
244
245Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
246Bugzilla Bug #112448)
247
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500248Centralize code which calculates the location of the superblock
249and block group descriptors so that it is in a single library routine.
250
Theodore Ts'o6826bde2003-08-21 02:14:44 -0400251Added two new functions, ext2fs_file_open2() and
252ext2fs_inode_io_intern2() which take a pointer to an inode structure.
253
254Fix compile_et to output the correct prototype for
255initialize_xxx_err_table_r() in the header file. (Addresses Debian
256bug #204332)
257
258In the lib/et makefile, make sure com_err.info is deleted on "make clean".
259
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400260Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
261present. This is for when we try stuffing an int into void * pointer.
262
263Fix type-punning which can cause gcc 3.x to miscompile code by getting
264confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
265and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
266**'. The EVMS code uses an ugly union approach since we don't want to
267modify the EVMS interfaces.
268
269Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
270aid build process on systems can use invoke GNU make as "gmake".
271
Theodore Ts'oc4c30b22003-12-07 02:16:43 -0500272Added regression testing for mke2fs.
273
274Fixed gcc -Wall nitpicks.
275
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500276Fixed various compiler warnings.
277
278Add portability fixes for FreeBSD and for using fsctl under Darwin to
279support ext2 ioctl's.
280
Theodore Ts'o858dd7b2003-08-02 20:48:35 -0400281
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400282E2fsprogs 1.34 (July 25, 2003)
283===============================
284
285Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
286a tight loop while waiting for a child fsck to exit in some cases.
287This burns CPU times which slows down the low-level filesystem check.
288
289Added code to mke2fs to assure that the default block size for a
290filesystem is at least as big as the sector size of the device, if it
291can be determined.
292
293Changed mke2fs and resize2fs to round the default size of a filesystem
294to be an even multiple of the VM pagesize in order to avoid a Linux
295kernel bug introduced when the storage of the buffer cache was moved
296into the page cache.
297
298Mke2fs will warn the user when creating a filesystem with journaling
299and a blocksize greater than 4096. (Addresses Debian bug #193773)
300
301Fixed a bug in resize2fs which caused it to fail on filesystems with a
302non-empty bad block list. Resize2fs now discards any blocks on the
303badblock list which are no longer part of the filesystem as the result
304of a filesystem shrink. (Note: this means that shrinking and then
305enlarging a filesystem is no longer a reversible operation;
306information about bad blocks in the part of the filesystem which is to
307be chopped off will be lost.)
308
309Changed resize2fs so the user can use prefixes to specify the units of
310the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
311and to make the error and informational messages explicitly display
312the blocksize used by the filesystem, in order to avoid confusion.
313(Addresses Debian bug: #189814)
314
315Added a new debugfs command, dump_unused, which dumps the contents of
316all unused blocks to stdout. (Useful as an emergency try-to-find
317deleted data command.)
318
319Added a new debugfs command, imap, which prints the location of a
320specified inode in the inode table.
321
322Fixed a bug in the badblocks program which caused it to use one bit of
323randomness in its non-destructive read/write test, instead of using a
324full 8 bits of randomness.
325
326Added a new option (-t) to badblocks, which allows the user to control
327the test pattern(s) used when checking a disk.
328
329The blkid probe function now more correctly detects UDF filesystems.
330
331Fixed a bug in the blkid library which caused it to not update its
332cache if a filesystem changes from having a label to not having a
333label.
334
335Fixed a bug in the blkid library wihch could avoid an infinite loop
336in blkid_find_dev_with_tag() if /proc is not mounted and there the
337/etc/blkid.tab file has not yet been created.
338
339Fixed the badblocks program so that the destructive read/write test
340honors the -c option, and to use O_DIRECT when possible to avoid
341thrashing the system block buffer cache.
342
343Fixed various NLS issues.
344 - Added Czech and Sweedish translations
345 - Removed testing NYC translation
346 - Fixed NLS support for message abbrevations in e2fsck
347 - Remove de-utf.po, since we shouldn't have two versions using different
348 charset encodings.
349 - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
350 simplify the statistics reporting in e2fsck.
351
352Changed configure.in so that its defaults for *BSD systems no longer
353build an fsck wrapper, and not to install in /usr/local by default.
354
355Fixed some minor spelling errors/typo's in e2fsck and the configure
356script.
357
358Fixed various Debian packaging issues (see debian/changelog).
359
360Updated and clarified man pages. (Addresses Debian Bug #195616)
361
362Programmer's notes:
363-------------------
364
365Fix gcc -Wall nitpicks.
366
367Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
368NLS support by default. (Added partial workaround for gettext/Darwin
369incompatibility problems.)
370
371Added full MIT KRB5 and Himdall compaibility support to the com_err
372library and the compile_et program. (Addresses Debian bug #191900)
373
374Added the blkid_known_fstype() function to the blkid library, which
375returns true if it is passed a filesystem type which is recognized by
376the blkid probing functions.
377
378Improved the documentation for the blkid library.
379
380Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
381returns the hardware sector size of a device, if it is available.
382
383Added a dependency in the blkid library's .so file to the uuid
384library, since the former uses the latter. (Addresses Debian bug
385#194094)
386
387Added --with-diet-libc and --disable-evms to the configure script.
388
389Fixed a minor memory leak in the badblocks program.
390
391Fixed a portability problem in tune2fs --- not all systems have strptime().
392
393Fixed a portability problem in debugfs with the use of getopt() more
394than once. Old-style BSD, new-style BSD, and Linux C libraries all do
395things differently.
396
397Add support Windows support to ext2fs_get_device_size().
398
399Added (normally disabled) debugging code to the Unix I/O manager which
400causes it to disable all userspace caching if the NO_IO_CACHE is
401defined.
402
403Changed the test I/O manager so it can always be linked into e2fsck,
404mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
405configure script. The test I/O manager will only print any debugging
406information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
407variables are set, which specifies which I/O operations are logged and
408a block number to watch, respectively. The log messages are sent to
409stderr by default, unless a filename is specified via the
410TEST_IO_LOGFILE environment variable.

Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400413E2fsprogs 1.33 (April 21, 2003)
Theodore Ts'o9c7ec172003-07-26 01:03:34 -0400414===============================
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500415
Theodore Ts'oba142c12003-04-16 00:59:59 -0400416Added a new utility program, logsave, which captures the output of a
417command in a log file, even if the containing directory hasn't been
418mounted yet (in which case the it saves the output in memory until it
419can write out the logfile). This is useful for capturing the
420output of fsck during the boot sequence.
421
422Fixed some portability problems that were causing problems under
423the Cygwin32 environment.
424
425Mke2fs now interprets a negative number to the -b option as a minimum
426block size.
427
428Fixed a bug in mke2fs which was incorrectly checking the argument to
429the -g option if the default block size was used. (Addresses Debian
430bug #188319)
431
432Fsck now explicitly ignores tmpfs and devpts, and it will complain if
433it can not find filesystem checkers for jfs, reseirfs, and xfs.
434
435E2fsck now updates the global free block and inode counters from the
436block group specific counters quietly. This is needed for an
437experimental patch which eliminates locking the entire filesystem when
438allocating blocks or inodes; if the filesystem is not unmounted
439cleanly, the global counts may not be accurate.
440
441Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
4422.0 is not yet supported; this only pulled in the bug fixes: fixed
443possible hangs caused by bugs in calling waitpid, and not setting the
444pipe to non-blocking mode; also fixed a file descriptor leak; made
445sure all functions call log entry/exit functions.)
446
447Badblocks now flushes its output file as bad blocks are discovered.
448
449The uuid library is now more paranoid about assuming the correctness
450of the /dev/random device; it mixes in a stream of bytes from
451random/srandom, just in case.
452
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500453Update Debian files to reflect the fact that I am now the Debian
Theodore Ts'oba142c12003-04-16 00:59:59 -0400454maintainer of e2fsprogs. Other various Debian-specific packaging
455cleanups.
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500456
457Move the source tarball generation functions from the top-level
458makefile to the util/gen-tarball script.
459
460Updated the Turkish .po translation file.
461
Theodore Ts'o1daf7582004-01-31 22:33:16 -0500462Added Heimdal and MIT krb5 extensions to the com_err library to make
Theodore Ts'o39d38b02003-03-30 23:45:02 -0500463it more compatible with com_err libraries from those distributions.
464
465Changed dumpe2fs to always display the superblock fields relating to
466the journalling and/or directory indexing feature even if those
467features are not enabled.
468
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500469Updated and clarify copyright statement vis-a-vis alpha releases of
470e2fsprogs.
471
472The ss library will now try to dynamically link to the readline
473library and use it if it is present in the system. This means that
Theodore Ts'oba142c12003-04-16 00:59:59 -0400474the debugfs program now has line editing and history features. The
475SS_READLINE_PATH environment variable is used to find a readline or
476readline-compatible library.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500477
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500478E2fsck now finds most duplicate filenames (all when rebuilding all
479directories via the -D option) and offers to delete or rename
480duplicate filenames/directory entries. (Addresses Debian Bug #176814).
481
482Fix bug in e2image. When writing out a raw image file, include data
483blocks from symlinks that do not store the symlink within the inode.
484
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500485Fix bug in resize2fs which incorrectly moved the block and inode
486bitmaps for sparse superblock filesystems and incorrectly marked
487blocks as in use. (Addresses Debian bug #174766)
488
489Added a new shared library, the blkid library, which efficiently
490allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
491and UUID filesystem specifiers without needing to search all of the
492devices in the system. Instead, the device is looked up in a cache
493file, and then verified to make sure the blkid cache is correct.
494
495Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
496the device name, using the blkid library. (Addresses Debian bugs
497#166048, #179671)
498
499Fsck now supports backslash escapes in /etc/fstab so that \040 can be
500used for spaces in device labels.
501
502Removed 32-bit limitations for debugfs's dump command.
503
504If the user specifies a large number of inodes, Mke2fs will
505automatically adjust the number of blocks per group to find a valid
506set of filesystem parameters.
507
508Add workaround to detect broken MD devices where when some of the
509underlying devices are marked read-only, writes to the MD device are
510silently dropped. E2fsck will detect if there is an attempt to run
511the journal twice, and abort with an error if this is the case.
512(Addresses IBM Bugzilla bug #1226)
513
514E2fsck will print an error if more than one of the -p/-a, -n or -y
515options are specified.
516
517E2fsck will fix HTREE corruptions in preen mode, without stopping the
518boot process. This is needed because the 2.4 ext2 filesystem
519accidentally had the INDEX_FL backwards compatibility code removed.
520
521Mke2fs no longer creates filesystems with the dir_index flag set by
522default; the user has to specifically request it.
523
524Update and clarified various man pages. (Addresses Debian bugs
Theodore Ts'oba142c12003-04-16 00:59:59 -0400525#173612, #175233, #175113, and #170497, #185945, #188318)
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500526
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500527Created man page for the mk_cmds program (from the libss library).
528
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500529Programmer's notes:
530-------------------
531
532Fix various gcc -Wall nits.
533
534Fixed a lot of portability problems that caused e2fsprogs not to build
Theodore Ts'oe5dced72003-03-15 04:28:17 -0500535successfully under Solaris and Apple/Darwin.
536
537Fixed a Makefile dependency to allow building e2fsprogs using parallel
538make jobs.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500539
540Changes to create a subset distribution which consists only of the
541et, ss, uuid, and blkid libraries. The configure script and top-level
542makefile were changed to support working with a subset distribution.
543
Theodore Ts'oba142c12003-04-16 00:59:59 -0400544Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
545actually used, and might people who are looking for
546EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
547
Theodore Ts'o508d7f32003-03-16 20:41:04 -0500548Updated debian files to fix a number of Lintian warnings.
549
550Updated config.guess and config.sub with newer versions from the FSF.
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500551
Theodore Ts'o71df0dc2003-04-21 16:17:09 -0400552Removed unnecessary libraries from being linked into the fsck, lsattr,
553chattr, and blkid executables.
554
Theodore Ts'o38513012002-11-09 15:00:56 -0500555E2fsprogs 1.32 (Nomvember 9, 2002)
556==================================
557
558Fixed a bug in the Unix I/O routines which caused needless writebacks
559of clean blocks from the unix_io cache (they were erroneously marked
560as being dirty, so they were getting written back to disk before
561getting evicted from the disk cache). This was harmless, but it
562significantly slowed down e2fsck.
563
564Made some other minor optimizations to the Unix I/O routines to save a
565small amount of CPU time.
566
567Updated internationalization files.
568
Theodore Ts'o3809bf12003-03-07 01:09:57 -0500569
Theodore Ts'oae65b292002-11-08 20:08:48 -0500570E2fsprogs 1.31 (Nomvember 8, 2002)
571==================================
572
573Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
574compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
575handling for child process that die unexpectly. Add a hack to force
576mkfs to create filesystems that won't cause problems with hardware
577that has 2k or 4k minimum blocksize requirements. Read from child
578processes in non-blocking mode, so that the GUI continues to update.
579
580Fix e2fsck so that it returns the appropriate exit code when the root
581filesystem has been changed, so that system's rc scripts will be told that
582the system needs to be rebooted.
583
584Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
585was set, some of the descriptor blocks that should have been written
586out were getting skipped.
587
588Changed e2fsck to force out changes to the backup copies of the
589superblock and block group descriptors when important changes are made
590to those data structures.
591
592Fix a bug where e2fsck could erroneously mark a filesystem as being
593clean if a check of dirty filesystem is interrupted with a ^C. (Bug
594introduced in e2fsprogs 1.28.)
595
596If journal debuging is enabled using --enable-jbd-debug, the debugging
597level is now set via the E2FSCK_JBD_DEBUG environment variable.
598
599If byteswapping support is disabled using configure --disable-swapfs,
600skip the tests which depend on byte-swapping, so that "make check"
601won't bomb out.
602
603Lshattr will now display the indexed directory flag. Also, some of
604the more esoteric compression flags are supressed unless compression
605support has been enabled.
606
607Update man pages.
608
609
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500610E2fsprogs 1.30 (October 31, 2002)
611=================================
612
613When resizing a filesystem, and inodes need to moved, resize2fs will
614update the inode's ctime field, and the mtime field of the containing
615directories, so that incremental backups using dump/restore will work
616correctly.
617
618In order to avoid spurious errors, e2fsck wil check the last
619superblock write time to determine whether or not it can safely use
620the LOW_DTIME checks to determine if there are inodes on the orphan
621inode linked list that had somehow gotten disconnected. (Addresses
622Sourceforge bug #620980)
623
624Partition in /proc/partitions that being with the string "lvm" are
625considered real partitions even if they do not end with a number.
626
627Fixed a bug in the the uuid generation function, where if /dev/urandom
628is not present, but /dev/random is, and there isn't sufficient
629entropy, the get_random_byte function could spin a loop forever.
630
631E2fsck, mke2fs, etc. will now reliably notice when image files are
632mounted using the loopback interface. (Addresses Sourceforge bug
633#619119)
634
635When flushing buffers (as is done by badblocks, for example) check to
636see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
637FDFLUSH ioctl which causes the MD device driver which causes confusing
638syslog messages about obselete ioctl messages. (Addresses Sourceforge
639bug #545832).
640
641Debugfs's write command now checks to see if the destination filename
642exists before creating it. (Addresses Sourceforge bug #478195.)
643
644When installing man pages, search for compressed man pages using all
645commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
646
647Fixed a bug in fsck where multiple filesystems specified on the
648command were not being checked in parallel due to a logic bug
649introduced to support the FSCK_MAX_INST environment variable.
650
651We have added a new superblock field, s_mkfs_time, which indicates
652when a filesystem was created. It is set via mke2fs, and printed out
653by dumpe2fs, but is not actually touched by the kernel.
654
655Dumpe2fs has been made more robust by not aborting if there is an
656error reading the block/inode bitmaps; instead it will still print out
657the location of the block/inode bitmaps and inode table.
658
659Add support for the an alternative block group descriptor layout which
660allows for on-line resizing without needing to prepare the filesystem
661in advance. (This is the incomat feature flag meta_bg.)
662
663Add support for storing default mount options in the superblock, so
664that the filesystem can be mounted with specific mount options without
665needing to specify them on the mount command line or in the /etc/fstab
666file.
667
668Add support for a new inode flag, which is to be used for indicating
669the top of directory hierarchies for the Orlov block allocator.
670
671Fix e2fsck so that if it creates the lost+found directory, it does so
672with the more apporpriate permissions of 0700. Also change
673mklost+found so that it also creates the directory 0700.
674
675Fixed format bug in e2fsck if NLS is in use.
676
677Add a German translation for e2fsprogs's NLS support.
678
679Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
680the beginning of the inode table. This won't matter much, since if
681there is a bad block at the beginning of the inode table, the root
682directory won't be available. But at least e2fsck won't crash in this
683case.
684
685Fixed endian problems in the htree code for e2fsck and debugfs.
686
687When byte-swapping a filesystem on a PPC architecture, byte-swap the
688bitmaps since the historical big-endian ext2 variant had byte-swapped
689bitmaps, and the ext2fs library assumes this. This fixes the
690regression test suite on PPC machines.
691
692Fix e2image so that it handles a bad block in the inode table
693appropriately.
Theodore Ts'od5e78102002-09-30 11:33:36 -0400694
695E2fsck now uses a more sophisticated algorithm to salvage corrupted
696directories that recovers more information in the corrupted directory
697block.
698
699E2fsck now performs additional consistency checks on indexed (HTREE)
700directories.
701
702Fix bug where efsck might get confused about whether a completely
703empty directory block is an empty leaf block or an interior htree
704node. This could cause e2fsck to get confused into think that a valid
705indexed directory was corrupted.
706
707E2fsck no longer creates an empty directory entry at the end of a
708directory block when optimizing a directory. This would cause some
709earlier versions of the dxdir kernel code to corrupt the directory
710when attempting to split a node containing an empty directory entry.
711
712E2fsck could sometimes in rare circumstances leave the indexed flag
713set after a small directory was optimized by compressing it instead of
714indexing it. (This should never happen in real life, since
715directories that small wouldn't have been indexed, but better safe
716than sorry.)
717
718E2fsck now only updates the master superblock in all cases. This
719slightly shortens its run time.
720
721Ext2ed can deal with directory entries of length 0; previously it
722would get stuck in an infinite loop.
723
724Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
725specifiers. (Sourceforge patch #613447)
726
727Badblocks will now work correctly on read-only devices such as
728CD-ROM's. (Sourceforge patch #600451)
729
Theodore Ts'o5d823a42002-11-01 02:13:53 -0500730Updated and clarified man pages. (Addresses Debian bug #167108)
Theodore Ts'od5e78102002-09-30 11:33:36 -0400731
732
Theodore Ts'oc6633052002-09-24 01:26:50 -0400733E2fsprogs 1.29 (September 24, 2002)
734===================================
735
736Fixed a bug in e2fsck which could corrupt a directory when optimizing
737it (via the -D option) or rebuiliding the hash tree index with a 1 in
738512 probability, due to a fence post error.
739
740Fixed a bug in the LVM support code which caused LABEL='xxx' not to
741work correctly.
742
743Mke2fs now enables the directory indexing flag by default. (Since
744this is a compatible feature flag, it's safe to do so.)
745
746Tune2fs will support setting the directory indexing feature flag. It
747will automatically set up the default hash algorithm and hash seed
748fields in the superblock.
749
750If the bone-headed user enters the root filesystem twice in
751/etc/fstab, the -R option which skips the root filesystem will skip
752all of them. (Addresses Debian bug #159423). Note! This is not a
753precedent for dealing intelligently with any other kind of doubled
754entry in /etc/fstab!
755
756
757Programmer's notes:
758-------------------
759
760Removed perror declaration in lib/et/internal.h. All modern systems
761can be expected to define perror() these days. Besides, the lib/et
762code wasn't using perror at all anyway. :-)
763
764
Theodore Ts'ob7bad612002-08-31 03:00:33 -0400765E2fsprogs 1.28 (August 31, 2002)
766================================
767
768Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
769for setting the htree flag is not included yet, although it can be
770manually turned on via the debugfs program.
771
772Clarified e2fsck error message which is printed when it cannot find
773sufficient contiguous block when relcating filesystem metadata.
774
775Added support for building an EVMS plugin module for ext2/3. This
776module is substantially the same as the EVMS module shipping with EVMS
7771.1, with one or two bugfixes. E2fsprogs can also build this plugin
778for use with EVMS 1.0 (which did not include the ext2 plugin module),
779if the configure --enable-old-evms flag is given.
780
781Fsck will search through EVMS volumes when trying to resolve
782filesystem specifications such as LABEL=xxx or UUID=xxx.
783
784Added a new utility program, /sbin/findfs, which will return
785filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
786the device name.
787
788Update and clarified various man pages. (addresses Debian Bug #145044,
789#146437, #131350, #151990, #144621, #141938)
790
791If there are no filesystems specified on fsck's command line, fsck now
792treat that as if the -As options were given. Previously it would
793simply do nothing. (Addresses Debian Bug #153102)
794
795Mke2fs no longer treats a failure to be able to clear the MD signature
796at the end of the filesystem as a fatal error. (Addresses Debian Bug
797#155007)
798
799The e2p library functions (which are used by lsattr and chattr) now
800double check to make sure the file is a regular file or directory
801before attempting to use the ext2 ioctls. Some device drivers
802unfortunately respond to the ext2 ioctl's with unknown behaviour.
803(Addresses Debian Bug #152029).
804
805The extended attribute handling has been updated to correspond with
806the latest V2 bestbits ACL code.
807
808Fixed bug in e2fsck which caused it to not clear the dtime field when
809processing truncated inodes on the orphan list. This could cause data
810loss(!) if a filesystem is rebooted before a truncate has been
811committed.
812
813E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
814algorithms. This makes e2fsck much faster in the case of severely
815corrupted filesystems where a large number of blocks are claimed by a
816large number of inodes. (Thanks to the 2.5 IDE device driver for
817inspiring this work.)
818
819Resize2fs has been significantly sped up when shrinking and expanding
820a filesystem by a very small number of blocks (for example, when EVMS
821is converting a partition to be an EVMS legacy volume).
822
823Added a new option to e2fsck, -D, which will optimize or compress all
824of the directories in the filesystem.
825
826E2fsck now catches SIGINT and SIGTERM to make sure it will can
827properly clean up and only exit at safe points. Fsck will pass
828SIGINT/SIGTERM to its child processes, and wait until they have all
829exited before it exits.
830
831The uuid parsing code in the uuid library now properly complains when
832an illegally formated uuid is presented to it. (Addresses Debian bug
833#152891)
834
835Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
836and 2.4.17, since the workaround can cause problems when using a 2.4
837kernel with an old version of glibc built with the 2.2 headers.
838
839Fixed a bug in mke2fs where it wasn't properly clearing the initial
840superblock used by other filesystems. (Addresses Debian bug #147256.)
841
842Added support for the synchronous directory feature written by Andrew
843Morton.
844
845The debugfs program can delete directories using the rmdir command.
846
847Add support for 8k and 16k filesystems (for systems with page sizes
848that are greater or equal to 8k or 16k, respectively). Note that
849these filesystems can not be mounted on x86 systems, or other systems
850with only 4k page sizes, due to limitations in the current Linux VM
851code.
852
853Resize2fs requires that the filesystem state be valid and have no
854errors; otherwise, e2fsck -f must be run first. (Previously it simply
855required that the last fsck time be greater than the last mount time.)
856
857Configure now defaults the man pages directory to /usr/share/man on
858Linux systems.
859
860E2fsck now offers to truncate inodes which contain too many blocks (so
861that i_blocks would overflow. Also fixed handling of large sparse
862files.
863
864E2fsck now more completely checks for symlink validity, including
865requiring NULL termination and length checks.
866
867E2fsck will offer to try forcing a disk write to remap a bad block
868after finding a read error when reading a filesystem metadata block.
869
870Fixed a bug in debugfs which caused the -b and -s options to crash
871debugfs, as well as breaking the testb, setb, and clearb functions.
872
873Added a bmap command to debugfs which calculates the logical to
874physical block mapping for a particular inode.
875
876Fixed a bug in code which checked to see if a device was mounted which
877sometimes (rarely) failed in the case of a plain file.
878
879Fixed a bug in resize2fs where when it reported an error, it would
880print a message erroneously indicating that the filesystem had been
881resized before it aborted.
882
883When resizing a plain file which is smaller than the requested size,
884resize2fs will attempt to extended the file so that programs like
885e2fsck will not complain that the file is too small.
886
887Resize2fs will print the actual new size of the filesystem when it is
888finished resizing.
889
890Fixed a bug in debugfs where "ls -l" would report incorrectl file type
891information on big-endian systems.
892
893
894Programmer's notes:
895-------------------
896
897Fixed collisions with C++ reserved words.
898
899Added portability fixes for building e2fsprogs on the HURD and AIX.
900
901Added the ext2ed program for creation of test cases. (ext2ed has many
902limitations and bugs which make it unsuitable for production use.)
903
904The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
905flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
906name_len field is byte swampped on big-endian machines, since in the
907V2 structure, name_len is a char field which is doesn't need to be
908byte swapped --- except if an old-style kernel had byte-swapped the
909name_len field as part of the V1 structure.

Theodore Ts'oa8e77242002-03-08 03:12:14 -0500912E2fsprogs 1.27 (March 8, 2002)
913==============================
914
915The warning messages for mke2fs now go to standard error.
916
917Fixed to make sure "make check" runs all of the test programs with
918LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
919
920The mke2fs program checks the boot sector for the BSD disk label, and
921avoids erasing it if it is there.
922
923Fixed a bug in e2fsck which caused it to core dump if the journal
924inode was missing when it was supposed to be there.
925
926E2fsck now prints ranges in pass 5 when printing deltas for the block
927and inode bitmaps.
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500928
929Debugfs's "ls -l" command now will print out the file type information
930in the directory entry.
931
932Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
933mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
934
935Debugfs can now examine the experimental directory indexing
936information.
937
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500938Fixed bug in debugfs which caused it to core dump if modify_inode is
939called without an open filesystem.
940
941The debugfs lsdel command now runs its output through a pager first.
942
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500943When installing manual pages, remove the compressed manual pages first.
944
945Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
946
947Fix the 2.4 resource limitation workaround introduced in 1.26 which
948actually broke things on mips32, sparc32, and Alpha platforms.
949
Theodore Ts'oa471ac52002-03-05 03:37:06 -0500950Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
951(which is required by the newer libintl libraries).
952
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500953Programmer's notes:
954-------------------
955
Theodore Ts'oa8e77242002-03-08 03:12:14 -0500956Fixed various gcc -Wall complaints.
957
Theodore Ts'oafa14ba2002-03-05 03:31:06 -0500958Fixed a few memory leaks in the e2fsck journaling code, and in the
959ismounted code checking for a swap device.
960
961Add new inode I/O abstraction interface which exports an inode as
962an I/O object.
963
964Exported ext2_file_flush as a public interface.
965
966In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
967
968Lots of small random portability fixes to make e2fsprogs build under
969AIX --- even without the 5L compatibility toolkit, and even using the
970uber-crippled AIX native C compiler.
971
972
Theodore Ts'o06987392002-02-03 01:36:54 -0500973E2fsprogs 1.26 (February 3, 2002)
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -0500974=================================
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -0500975
Theodore Ts'o446314f2001-12-24 15:22:27 -0500976Dumpe2fs will keep going now if the bad block inode can't be read.
977(Previously it stopped with a fatal error.)
978
979E2fsck will now give an opportunity to run the journal even if the
980recovery flag is not set. This is the default behaviour if e2fsck is
981using a backup superblock, since the needs_recovery flag will never be
982set in the backup superblock copies.
983
984E2fsck now automatically finds the backup superblock/group descriptors
985even when the primary superblock is completely destroyed for 2k and 4k
986filesystems. (Previously it just guessed/assumed that we were dealing
987with a 1k filesystem in that case, and users had to manually specify
988the backup superblock number.)
989
990Fixed a bug in e2fsck where it dereferences a null pointer when there
991is a problem opening a filesystem in preen mode.
992
993E2fsck now handles external journals correctly; previously it trashed
994the external journal device if the journal needed to be replayed.
995
996Work around ulimit incompatibility problem caused by recent 2.4
997kernels; the unix IO module will automatically try to set any resource
998limits to be infinite on startup.
999
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001000Fixed a bug in e2fsck where it wasn't allocating a new block or inode
1001bitmap if it wasn't present and the blocksize was 2k or 4k.
Theodore Ts'o9c7ec172003-07-26 01:03:34 -04001002 (Addresses Debian Bug #116975)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001003
1004E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
1005clearing the new V2 fields if they do not make sense or if the ext3
1006superblock is version 1 superblock.
1007
1008E2fsck will automatically relocate the ext3 journal from a visible
1009file (i.e., /.journal) to an hidden inode if the filesystem has been
1010opened read/write. This allows the users to add a journal while the
1011filesystem is mounted, but the next time the system is rebooted, the
1012journal file will disappear. This avoids problems with backups,
1013stupid operators with superuser bits, etc.
1014
1015Fix a bug in fsck where it would not support a filesystem type of
1016"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
1017
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001018Fsck now supports fstab entries of the form "ext3,ext2". It will also
1019automatically identify reiserfs filesystems.
1020
1021The number of processes spawned by fsck can now be limited using the
1022FSCK_MAX_INST environment variable.
1023
Theodore Ts'o446314f2001-12-24 15:22:27 -05001024Fsck now searchs the LVM proc hierarchy to find logical volumes which
1025should be searched for UUID and label information.
1026
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001027Work around a bug in 2.4.10+ kernels by trying to unset the filesize
1028limit if at all possible, when opening a block device. (The filesize
1029limit shouldn't be applied against writes to a block device.)
1030
Theodore Ts'o446314f2001-12-24 15:22:27 -05001031In mke2fs and e2fsck, specifying the -c option twice will now do
1032a read/write test on the disk. Update the man pages to encourage
1033using the -c option, and to discouraging running badblocks separately,
1034since users tend to forget to set the blocksize when running
1035badblocks.
1036
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001037Mke2fs now automatically clears the immutable attribute on a
1038pre-existing .journal file left over from a previous failed attempt to
1039add a journal to an alreadyy-mounted filesystem.
1040
1041Fixed mke2fs's exit codes to consistently indicate when the mke2fs
1042operation failed.
1043
Theodore Ts'o446314f2001-12-24 15:22:27 -05001044Mke2fs now creates the lost+found directory with permissions of 0700,
1045so that files that had previously lived in protected directory are
1046safe if they get dropped in lost+found and the system administrator
1047doesn't deal with immediately. (Addresses Debian #bug 118443)
1048
1049Mke2fs and e2fsck (and all programs that use the
1050ext2fs_check_if_mounted function) will now properly identify that a
1051device is mounted, even in cases where devfs has confused things with
1052multiple devices names with the same identity, or if a dim-witted
1053system administrator has done something stupid like creating device
1054file aliases in their home directory. Also now checks for swap devices
1055by using /proc/swaps. (Addresses Debian bug #106622)
1056
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001057Added a new option (-T) to tune2fs which sets the time a filesystem
1058was last checked.
1059
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001060Speed up e2image when creating sparse raw image files by optimizing
1061away excess lseek() system calls.
1062
1063Fix support of large (> 2GB) files when used as a filesystem in
1064mke2fs, tune2fs, debugfs, and findsuper.
1065
1066Debugfs's stat and icheck commands now properly deals with large (>
10672GB) files.
1068
1069Debugfs's set_super_value command now prints out the list of valid
1070superblock fields which can be set using the command.
1071
Theodore Ts'o446314f2001-12-24 15:22:27 -05001072Debugfs's rm and kill_file command now updates the superblock free block
1073and inode counts, thus keeping the filesystem consistent.
1074
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001075Debugfs's lsdel command now takes an optional argument which allows
1076the user to only see the most recently deleted files.
1077
1078A new command (undel) was added to debugfs which automates
1079undeleting a deleted inode and linking it back to a directory.
1080
1081Debugfs's ls command now takes a new option, -d, which lists
1082deleted directory entries.
1083
1084Debugfs's testb, freeb, setb, and find_free_block commands now take an
1085optional count argument.
1086
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001087Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
1088be used to signal that a particular inode should not be eligible for
1089tail-merging --- this is needed for programs like LILO.
1090
1091The findsuper (an unreleased, uninstalled utility program) has been
1092improved to add extra validity checks and to add a progress meter.
1093(It is still an unsupported program; the officially supported way to
1094recover from a trashed partition table is to use gpart; findsuper is
1095for wizards only. :-)
1096
1097Debugfs was fixed to compile with "configure --disable-swapfs".
1098
Theodore Ts'o446314f2001-12-24 15:22:27 -05001099Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
Theodore Ts'ocd1a79a2001-11-27 03:36:42 -05001100
1101Added new translation file for Turkish.
1102
Theodore Ts'o446314f2001-12-24 15:22:27 -05001103Programmer's notes:
1104-------------------
1105
1106Fix general gcc -Wall complaints.
1107
1108E2fsprogs (mostly) works with the dietlibc.
1109
1110The programming texinfo file has been expanded to include description
1111of additional libext2fs functions. (Still not compeltely done, but a
1112lot of the more important functions have been documented.)
1113
1114Added a umask structure to struct_ext2_filsys, which currently only
1115modifies the behaviour of ext2fs_mkdir(), but if we add any file
1116creation functions to libext2fs, we should also make sure they respect
1117the umask setting.
1118
Theodore Ts'oa5f3f5c2002-02-03 01:00:22 -05001119The build-rpm script was fixed to be a bit more safe.
1120
1121The tests' Makefile now has a way of automating test case creation
1122for e2fsck, using "make testnew".
1123
1124Created a new function, ext2fs_dir_iterate2 which passes more
1125information to the callback function (identical to the one used by
1126ext2fs_dblist_dir_iterate). The directory iterator functions take a
1127new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
1128directory entries. If the directory entry is deleted, the callback
1129function will be called with the entry paraemter set to
1130DIRENT_DELETED_FILE.
1131
1132Added new functions, ext2fs_inode_alloc_stats and
1133ext2fs_block_alloc_stats, which takes updates block/inode allocation
1134statistics in the bitmaps, block group descriptors, and superblock
1135when inodes or blocks are allocated or deallocated.
1136

Theodore Ts'od08a4ce2001-09-20 09:47:42 -04001138E2fsprogs 1.25 (September 20, 2001)
1139===================================
1140
1141This is primarily a bug-fix release; no new features were added, but
1142there are a number of embarassing bug fixes and cleanups applied.
1143
1144Fix a bug mke2fs which causes stack garbage to be written to disk when
1145zapping disk sectors. (This bug could cause mke2fs to core dump for
1146some kernels, I suspect with security enhancement patches.)
1147
1148Remove unneeded #include of <linux/config.h> which was breaking
1149building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
1150
1151Updated tune2fs man page to reflect the fact that adding or removing a
1152journal doesn't require running e2fsck.
1153
1154Remove use of AC_REQUIRE from autoconf which had been used to prevent
1155AC_CANONICAL_HOST from being called twice; unfortunately this causes
1156recent autoconf to bomb out since they don't allow AC_REQUIRE to be
1157used outside of autoconf macros. Fortunately, it doesn't seem to be
1158necessary any more, anyway.
1159
1160E2fsck will now not fall back to an alternate superblock if the user
1161specifies the superblock location explicitly on the command-line.
1162This allows easier recovery from a situation where the primary
1163superblock and block groups are slightly corrupted, but the backup
1164superblocks are completely broken.
1165
1166Fix problem which caused compile_et and mk_cmds to blow up if
1167e2fsprogs was in a directory with a pathname that contained spaces.
1168
1169We are now more paranoid about checking the entry in /etc/mtab to make
1170sure the filesystem is really mounted, since some broken distributions
1171(read: Slackware) don't initialize /etc/mtab before checking non-root
1172filesystems. (Slackware also doesn't check the root filesystem
1173separately, and reboot if the root filesystem had changes applied to
1174it, which is dangerous and broken, but there's nothing I can do about
1175that.)
1176
1177Make UUID library C++ friendly by adding appropriate extern "C"
1178declarations and using const in the function declarations.
1179
1180Fix up the com_err texinfo file so that it can product a valid info
1181file (previously, it could only be used to generate paper
1182documentation using texinfo.tex).
1183
1184
Theodore Ts'ofb707752001-09-04 15:00:37 -04001185E2fsprogs 1.24a (September 2, 2001)
1186===================================
1187
1188Fix brown-paper bug in mke2fs which caused it to segfault when
1189printing the version string.
1190
1191
Theodore Ts'o109624a2001-08-31 00:59:55 -04001192E2fsprogs 1.24 (August 30, 2001)
1193================================
1194
1195Revert the BLKGETSIZE64 support, since for some distributions, this
1196ioctl has been used by an unofficial kernel patch to update the last
1197sector on the disk, and this was causing disk corruption problems as a
1198result.
1199
1200Mke2fs is now more careful about zapping swap space signatures and
1201other filesystem/raid superblock magic values so that programs like
1202mount who try to use hueristics to determine the filesystem type of a
1203partition are less likely to be confused.
1204
1205E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
1206regular file (since Andreas Dilger's on-line resizing tools will set
1207its mode bits).
1208
1209Fixed some minor texinfo, man pages nits for spelling errors,
1210texinfo warnings, etc. (Addresses Debian bug #110621.)
1211
1212E2fsprogs program no longer print the filesystem version number
1213(i.e. 0.5b), since it only confuses people and doesn't serve any real
1214purpose.
1215
1216E2fsck will once again compile under libc5, since it will supply its
1217own version of strnlen if necesssary.
1218
1219mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
1220when specifying the external journal device. tune2fs will also search
1221devices looking for the externla journal debice when removing.
1222
1223E2fsprogs 1.23 (August 15, 2001)
1224================================
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001225
1226Add initial support for extended attributes (EA); e2fsck will
Theodore Ts'o6c0a0412001-07-23 00:23:52 -04001227correctly handle a filesystem with EA's and check the EA blocks for
1228corruptions.
1229
Theodore Ts'od494bba2001-08-09 06:14:42 -04001230E2fsck's symlink sanity checking has been cleaned up. It now checks
1231the i_size value of fast symlinks, and checks for immutable flags
1232being set of symlinks, etc.
1233
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001234E2fsck now offers to clear inodes which are special files that have a
1235non-zero i_blocks or i_size field. (The i_size field check was in the
1236previous version of the code, but due to a bug it didn't offer to
1237clear the inode unless i_size and i_size_high were both non-zero.)
1238
Theodore Ts'od494bba2001-08-09 06:14:42 -04001239E2image can now create "raw" image files, which only contain the
1240filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
1241debugfs, etc., can be run directly on the raw image file.
Theodore Ts'obf16d102001-07-27 22:20:06 -04001242
1243Add support for the 64-bit block device patches.
1244
1245Fixed bugs in creating external journals with a 1k blocksize.
1246
Theodore Ts'od494bba2001-08-09 06:14:42 -04001247Add initial support for external journals (so long as the external
1248journal only supports a single filesystem) in e2fsck.
1249
1250Remove requirement for needing to run fsck on a filesystem after
1251removing a journal (either internal or external).
1252
Theodore Ts'obf16d102001-07-27 22:20:06 -04001253The man pages now document how to create and manage external journals.
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001254
1255Speed up the check of an ext3 filesystems by avoiding a needless flush
1256of all of the superblock and block group descriptors.
1257
Theodore Ts'od494bba2001-08-09 06:14:42 -04001258Speed up creating an internal journal using tune2fs in the case where
1259the filesystem has a lot blocks already allocated.
1260
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001261Tune2fs has been fixed to make sure that only error messages go to
1262stderr, and normal message go to stdout. (Addresses Debian bug #108555)
1263
Theodore Ts'od494bba2001-08-09 06:14:42 -04001264Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001265now not set the sparse_super feature. (Addresses Debian bug #108165)
Theodore Ts'od494bba2001-08-09 06:14:42 -04001266
Theodore Ts'od1ef5c32001-07-20 12:35:11 -04001267Add support in fsck for the filesystem type "auto".
1268
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001269Fsck -A will not try to interpret device names for filesystems which
1270have a pass number is 0. (Addresses Debian bug #106696).
1271
1272Fsck prints a warning message if now valid filesystems are passed to
1273it. (Addresses Debian Bug #107458.)
1274
Theodore Ts'o9249d982001-07-20 18:14:10 -04001275E2fsck now gives an explicit warning if there filesystem still has
1276errors at the end of the run. (Addresses Debian bug #104502)
1277
Theodore Ts'od494bba2001-08-09 06:14:42 -04001278E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
Theodore Ts'oc4ac9e12001-08-15 21:02:23 -04001279reflects an error. E2fsck will also not run the orphan list if the
1280filesystem contains errors, since the orphan list might be corrupted.
Theodore Ts'od494bba2001-08-09 06:14:42 -04001281
1282E2fsck now prints the number of large files when given the -v option.
1283
1284Fixed minor memory leaks in e2fsck.

Theodore Ts'o19d6b542001-06-23 00:13:09 -04001289E2fsprogs 1.22 (June 22, 2001)
1290==============================
1291
1292Fixed a bug in e2fsck's handling of orphan inodes which are special
1293files (i.e., block/character device files, named FIFO's, etc.).
1294
1295Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
1296tune2fs to fail at adding a journal to a mounted filesystem.
1297
1298Fixed a few big-endian bugs in e2fsprogs
1299 * The directory block functions were accidentally reporting
1300 some directories as corrupted when they weren't.
1301 * If e2fsprogs is compiled --disable-swapfs, the C language
1302 equivalents weren't being included for big-endian platforms.
1303 (Fixes Debian bug #101686).
1304
1305Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
1306
1307Programmer's notes:
1308-------------------
1309
1310Use platform independent method of defining the BLKFLSBUF and FDFLUSH
1311ioctls, and allow them to be defined for non-i386 platforms.
1312
1313The uuid.h header file is now protected against multiple inclusions.
1314
1315E2fsprogs is now being developed using BitKeeper. Changed the test
1316scripts to deal with BK's stripping CR characgters from text files,
1317and changed the top-level Makefile.in to avoid including BitKeeper
1318files when generating the source tarball.

Theodore Ts'ob90b8262001-06-15 22:54:34 +00001321E2fsprogs 1.21 (June 15, 2001)
1322==============================
Theodore Ts'o767de092001-06-02 01:20:18 +00001323
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001324Added new configure flags which allow a subset e2fsprogs to be built;
1325this is most useful for boot floopies, since the resulting shared
1326libraries and programs are slimmed down by removing features that
1327aren't necessary for a boot floppy. The new flags that were added
1328are: --disable-swapfs, which removes support for byte swapping old
1329legacy PPC/68k filesystems, --disable-debugfs, which removes support
1330for debugfs from the libext2fs library, --disable-imager, which
1331removes support for the e2image program, and --disable-resizer, which
1332removes support for resize2fs.
1333
1334E2fsck now prints the number of mounts or days elapsed since the last
1335check when e2fsck is forced to check an otherwise clean filesystem.
1336
1337Tune2fs now prints an informative message about how often a filesystem
1338will be checked when adding a journal to the filesystem, to remind the
1339user that he/she may want to adjust those parameters using tune2fs
1340-c/-i.
1341
1342Worked around hurd brain-damage which causes e2fsck to sometimes
1343believe a filesystem is the root filesystem based on device numbers
1344(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
1345violation).
1346
1347Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
1348erroneous error with the -F option was specified.
1349
1350Fixed a ext3 recovery bug in the revoke handling; synchronized with
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001351ext3 0.7a.
1352
Theodore Ts'o767de092001-06-02 01:20:18 +00001353Fixed two bugs in e2fsck's handling of dup block handling, dealing
1354with relatively uncommon edge cases: a directory with an indirect
1355block which is claimed by another file, and when the last inode in the
1356filesystem has blocks claimed by another file.
1357
Theodore Ts'o5a9c0362001-06-02 04:55:57 +00001358E2fsck now checks to see if the i_size field of a fast symlink is too
1359big, and offers to clear the symlink if so.
1360
1361E2fsck now checks to see if i_size_high of special files is non-zero,
1362and offers to clear i_size_high.
1363
Theodore Ts'o767de092001-06-02 01:20:18 +00001364Fix e2fsck's handling of incompatible journal flags so that the user
1365has chance to abort, and then has the option to clear out the journal
Theodore Ts'oe3338452001-06-14 07:11:33 +00001366entirely. (Addresses Debian bug #98527.)
Theodore Ts'o767de092001-06-02 01:20:18 +00001367
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001368Fixed a bug in fsck which could cause it to core dump if a mix of
1369standard and non-standard device names are used in /etc/fstab.
1370(Debian bug #100559)
1371
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001372Fixed a bug in debugfs which caused read errors when copying a file to
1373not be noticed.
1374
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001375The debugfs set_super_value command can now modify the s_lastcheck field.
1376
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001377Fixed a bug in lsattr and chattr which was accidentally introduced in
13781.20 to support > 2GB files; both lsattr and chattr wasn't reading
1379directories correctly because the change modified the layout of struct
1380dirent to be incompatible with the libe2p shared library.
1381
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001382Cleaned up the mke2fs manual page and included a discussion about why
1383it's good to periodically check the filesystem even when journaling is
1384enabled.
1385
Theodore Ts'o767de092001-06-02 01:20:18 +00001386Programmer's notes:
1387-------------------
1388
1389Fix general gcc -Wall complaints.
1390
1391The types needed by the ext2 header files are now provided by
1392lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
1393
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001394Integers are now preferred to longs when trying to find a 32-bit type
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001395in ext2_types.h. Also, if linux/types.h has already been defined,
1396don't try to redefine the types.
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001397
Theodore Ts'o767de092001-06-02 01:20:18 +00001398Fixed make depend script so that it automatically corrects the
1399pathname cleanups performed by make -M, so I don't have to fix them up
1400by hand.
1401
1402Fixed the d_loaddump test case to be more robust, and not depend on
1403bash'isms.
1404
1405Removed debugfs's dependence on pread(), which was accidentally
1406intrudced in e2fsprogs 1.20
1407
Theodore Ts'oc05b5522001-06-08 12:03:36 +00001408Fixed a performance bug in the libext2fs's icount routine; the size
1409estimate of the icount array was incorrectly being calculated.
1410
Theodore Ts'ob90b8262001-06-15 22:54:34 +00001411Removed use of the badblocks compatibility functions in the e2fsprogs
1412programs.
1413
1414Added paranoia code which protects against strange cases where /etc
1415isn't on the root filesystem, or if /etc/mtab doesn't exist.
1416
1417The header file ext2_types.h is now installed.
1418
1419Autoconf is used to determine when we are on big-endian machines,
1420instead of doing run-time tests, to save a few bytes of code.
1421
1422The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
1423functions are no longer inline functions, which saves space and
1424doesn't really cost any real performance.
1425
1426The ext2fs library no longer depends on the e2p library. (What need
1427there was of it --- namely, fsetflags, was coded in-line).
1428
1429Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
1430when the user is stupid and tries compiling the package using "make
1431install" as root.
1432
1433Miscellaneous code cleanups:
1434 * Added missing files from Makefile.in's SRCS file, so that
1435 their dependencies would be properly calculated.
1436 * Removed redundant code
1437 * Fixed comments in code
1438 * Removed no-longer unneeded argsused #pragma.

Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001441E2fsprogs 1.20 (May 20, 2001)
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001442=============================
Theodore Ts'o5570a652000-08-21 01:23:39 +00001443
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001444Add support for replaying the ext3 journal purely in user mode,
1445including handling the orphaned inode list. Used code contributed by
1446Andreas Dilger, with bug fixes and the orphaned inode handling done
1447by Theodore Ts'o.
1448
1449The mke2fs and tune2fs programs can create or modify a filesystem to
1450include an ext3 journal. Tune2fs also can be used to remove an ext3
1451journal from a filesystem.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001452
1453E2fsck will now check for the existence of a linked list of orphan
1454inodes in the superblock, and clear those inodes before starting the
1455rest of the filesystem check (but after the journal playback).
1456
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001457E2fsck now validates the file descriptor passed to the -C option,
1458which saves against the completion bar getting written to an
1459unexpected location, such as the disk being checked. (Debian
1460bug/wishlist #55220)
1461
1462E2fsck will now bump the filesystem revision number from zero to one
1463if any of the compatibility bits are set.
1464
1465Fixed a bug where a badly corrupted directory on a big endian system
1466could cause e2fsck to die with a bus error. The
1467ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
1468the ext2 library now does alignment sanity checks on the rec_len field
1469of the directory entry before using it.
1470
1471The ext2 library has been enhanced to make tune2fs safe to run on
1472mounted filesystems. (Users could usually get away with using tune2fs
1473on mounted filesystems before, but with the advent of ext3 and
1474journaling, it became important to make tune2fs was *really* safe for
1475use even when the filesystem being modified is mounted.) E2label is
1476now implemented by tune2fs using an argv[0] dispatch, so that e2label
1477is also now safe for use on mounted filesystems.
1478
1479Added a new program, e2image, which creates a backup of critical ext2
1480filesystem data structures. The generated image file can be examined
1481using dumpe2fs and debugfs. In the future, e2fsck will be able to use
1482the image file to help recover very badly damaged filesystems.
1483
1484Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
1485no longer cause e2fsck to bomb out. Also treat files > 2GB as being
1486large file when deciding whether or not the filesystem has large files.
1487
1488Fixed lsattr and chattr so that they work correctly on large files.
1489(Fixes Debian bug #72690.)
1490
1491Removed limitation in get_device_size() which imposed a one terrabyte
1492filesystem limitation. (Most 2.2 kernels still have a signed int
1493problem which cause 1 TB block device limitation. Fortunately, the
1494kernel patches to fix this are much easier than fixing the 2TB
1495limitation in the kernel. :-)
1496
1497A max_mount_count of zero is now treated as if no mount count were
1498set. (Previously, no mount count was indicated by using -1, and a
1499mount count of zero caused e2fsck to always be run.)
1500
Theodore Ts'o77648562001-05-14 13:04:44 +00001501Mke2fs supports two new filesystem types largefile and largefile4.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001502
1503Mke2fs now adds some randomness in s_max_mount_count so that multiple
1504filesystems won't be all checked at the same time under normal
1505operations.
1506
Theodore Ts'o5570a652000-08-21 01:23:39 +00001507Fixed bug in the progress bar printing code which could cause e2fsck
1508to core dump on an illegal filesystem.
1509
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001510Fixed bug in fsck which could allow more than one instance of e2fsck
1511to be printing a progress bar. (Debian bug #65267)
1512
Theodore Ts'o5570a652000-08-21 01:23:39 +00001513Fsck using a UUID or a LABEL specifier will work even if devfs is
1514compiled into the kernel and not mounted. If the pathnames in
1515/proc/partitions are incorrect, fsck will search /dev for the correct
1516device (using the new ext2fs_find_block_device library function).
1517Fsck now also checks the RAID devices first so that they are properly
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001518found when they are in use. Support has also been added to support
1519additional IDE disks and the DAC 960 device names. (Debian bug #94159)
1520
1521Fixed a bug in fsck which caused it not deal properly with 16
1522byte long filesystem labels.
Theodore Ts'o5570a652000-08-21 01:23:39 +00001523
Theodore Ts'o5a009bb2001-05-21 05:27:45 +00001524Fsck's -t option has been made a lot more flexible. The semantics for
1525what happens if a comma-separated list to fsck has been regularized,
1526and it is now possible to filter what filesystems will get checked
1527based what is in the filesystem's fstab entry's option field. (Debian
1528bug #89483.)
1529
Theodore Ts'o5570a652000-08-21 01:23:39 +00001530The dumpe2fs program can now print out the group description
1531information in hex, and also prints the location of the superblock and
1532block group descriptor for those block groups that have them.
1533
1534Mke2fs now clears the ext2 superblock before it starts creating a
1535filesystem, so that the superblock magic number is only written if the
1536filesystem creation process successfully completes.
1537
1538The debugfs program's stat command now pretty-prints the blocks used
1539by an inode so that it's more compact and informative.
1540
1541The debugfs stats command now uses the same libe2p code (which is used
1542by dumpe2fs) to print the superblock header information. This is more
1543complete, and it avoids a bit of code duplication.
1544
1545Added a new debugfs command, set_super_value (ssv) which allows the
1546user to set arbitrary superblock fields.
1547
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001548Debugfs was extended to support inode numbers in hex (by prefixing
1549them with 0x), and so that modify_inode can set the inode generation
1550number. Also, there is now a new function command called logdump
1551which will dump an ext3 journal.
1552
1553Fixed a bug in debugfs so that quitting out of the pager doesn't kill
1554debugfs.
1555
1556Debugfs's dump command now stops immediately upon reporting a disk
1557read error. (Fixed a bug in ext2fs_file_read library routine which
1558caused debugfs not to stop.) (Debian bug #79163)
1559
1560On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
1561checked before /etc/mtab is used, since /proc/mounts is more likely to
1562be accurate.
1563
1564Added portability fixes for Solaris and Linux/ia64.
1565
1566Various manual pages were clarified and cleaned up. (Fixed debian
1567bugs #63442, #67446, and #87216)
1568
Theodore Ts'o5570a652000-08-21 01:23:39 +00001569
1570Programmer's notes:
1571-------------------
1572
1573The e2fsck message printer now supports %Iu and %Ig, which will print
1574out the inode's user and group owners, respectively.
1575
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001576E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
1577that no longer dependent on the system having the correct version of
1578the kernel header files.
1579
Theodore Ts'o5570a652000-08-21 01:23:39 +00001580Added a new function to libext2, ext2fs_find_block_device(), which
1581searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
1582device given its device number.
1583
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001584Added a new function to libext2, ext2fs_sync_device, which centralizes
1585all of the places which might try to use the BLKFLSBUF or FDFLUSH
1586ioctls (and usually failing to define them since the system header
1587files don't usually do this for us, and we're trying to avoid usage of
1588kernel include files now).
1589
Theodore Ts'o5570a652000-08-21 01:23:39 +00001590Added new utility programs in tests/progs: random_exercise and
1591hold_inode. They aren't built by default; they're useful for
1592exercising ext3 filesystem code.
1593
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001594Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
1595the filesystem close functions to only update the superblock, and to
1596not touch the block group descriptors. Needed by tune2fs when
1597modifying a mounted filesystem.
1598
1599Got rid of struct ext2fs_sb and replaced it with the standard struct
1600ext2_super_block from include/linux/ext2_fs.h. Note: this may break
1601source (but not binary) compatibility of some users of the ext2
1602library. Those applications should just simply do a global search and
Theodore Ts'o7d614e32001-06-13 23:49:05 +00001603replace of struct ext2fs_sb with struct ext2_super_block, and include
1604the new header file <ext2fs/ext2_fs.h> which defines it.
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001605
1606The ino_t type has been renamed ext2_ino_t to protect applications
1607that attempt to compile -D_FILE_OFFSET_BITS=64, since this
1608inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
1609unexpected ABI change.
1610
1611The Makefiles have been reworked so that "make check" can be run from
1612the top-level Makefile.
1613
1614Fix general gcc -Wall complaints and removed dead code.
1615
1616Remove use of NOARGS, because we assume everyone does ANSI C these
1617days.
1618
1619Added build-rpm script from sct.
1620
1621New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
1622to support e2image.
1623
1624New function ext2fs_flush_icache which must be called if the
1625application program modifies the inode table blocks without going
1626through ext2fs_write_inode() interface.
1627
1628New ext2fs_check_mount_point() function, which will return the mount
1629point of a device if mounted.
1630
1631The io_channel abstraction now has an optional interface,
1632io_channel_write_range, which allows specific byte ranges to be
1633written.
1634
1635The unix_io IO channel now supports write-through caching, so that
1636journal creation is more efficient.
1637
1638Added x86 assembly language routines to support byte swapping, to
1639reduce executable size.
1640
1641Fixed bug in the utility program subst so that it's possible to
1642replace a substitution variable with a zero-length string.
1643
1644Fixed numbering e2fsck pass1 problem numbers; an extra zero had
1645slipped into some of the problem number.

Theodore Ts'ob777e262000-07-27 01:39:23 +00001647E2fsprogs 1.19 (July 13, 2000)
1648==============================
Theodore Ts'oab146762000-07-07 04:37:35 +00001649
1650Release the resize2fs program since the timeout before it could
Theodore Ts'o006ea712000-08-21 03:39:49 +00001651be released under the GPL has finally expired.
Theodore Ts'oab146762000-07-07 04:37:35 +00001652
1653Add experimental support needed for the ext2 compression patches.
1654This requires compiling e2fsprogs with the --enable-compression flag
1655to the configure script.
1656
1657Added ext3 journalling support. E2fsck will run the journal (if
1658necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
1659installed as a symlink to e2fsck. Fsck has been taught about ext3,
1660and treats it the same as ext2 in terms of the progress bar logic.
1661Dumpe2fs will display the superblock journaling information if the
1662filesystem has a journal. The ext2 library will now permit opening an
1663ext3 filesystem with the recovery flag set. This is necessary for
1664on-line dump's to work correctly, but there may be issues with this
1665working well since ext3 is much less agressive about syncing blocks to
1666the filesystem, since they're safe on the journal.
1667
1668Tune2fs and e2fsck have been changed to allow the mount_count check to
1669be disabled by setting max_mount_count to -1. (This was already
1670supported by the kernel.)
1671
1672Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
1673are used for ext3 as well.
1674
1675Added internationalization support for e2fsprogs; must be enabled
1676by passing --enable-nls to configure.
1677
1678Always use the provided ext2fs header files to insulate ourselves from
1679kernel version changes. Which include files are used by e2fsprogs
1680have also been cleaned up to improve portability.
1681
1682Limit the number of times that e2fsck updates the progress bar so that
1683people who are booting using a 9600 baud console don't get swampped by
1684too many updates.
1685
1686Improved the loop detection algorithm in e2sck's pass #3 so that it is
1687much, much faster for large filesystems with a large number of
1688directories.
1689
1690The memory footprint for e2fsck is now slightly smaller than before.
1691
1692E2fsck now checks if special devices have a non-zero size, and offers
1693to clear the size field if it finds such an inode.
1694
1695E2fsck now checks if special devices have the append-only flag set,
1696and offers to clear the inode.
1697
1698E2fsck now properly handles some "should never fail" cases during a
1699bitmap copy in pass5.
1700
1701E2fsck now properly prints control characters in filenames as ^A .. ^Z.
1702
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001703E2fsck now calculates the correct location of the backup superblock in
1704the case of filesystem blocksizes > 1k.
1705
1706Fixed a bug in e2fsck's calculation of the number of inodes_per_block
1707which normally didn't cause problems under most filesystem parameters,
1708but could cause a valid superblock to be rejected in extreme cases.
1709Other checks for validating superblock values were made more
1710stringent.
1711
Theodore Ts'oab146762000-07-07 04:37:35 +00001712Added non-destructive write testing to the badblocks program, courtesy
1713of David Beattie. The badblocks also now has an option to input the
1714current set of bad blocks, so that known bad blocks are skipped to
1715speed up the badblocks test. There is also a persistent rescan
Theodore Ts'o006ea712000-08-21 03:39:49 +00001716feature which causes badblocks to run until it has completed some
1717number of passes without discovering any new bad blocks.
Theodore Ts'oab146762000-07-07 04:37:35 +00001718
1719Badblocks now checks to see if the device is mounted and refuses to do
1720the tests involving writing to the device if it is mounted. Also,
1721badblocks now allows the number of blocks to be checked to be
1722defaulted to the size of the partition.
1723
1724Fixed a bug in fsck which didn't allow non-root users to be able to
1725check filesystems if there were any LABEL= or UUID= entries in
1726/etc/fstab.
1727
1728The Hurd doesn't support the filetype filesystem feature. The mke2fs
1729program now makes sure that for the Hurd, the filestype feature is
1730turned off. E2fsck will check to see if the filetype feature is
1731turned on for Hurd filesystems, and offer to turn off the feature.
1732
1733Mke2fs now has a safety check to make sure the number of blocks do not
1734exceed 32 bits even on a 64 bit platform.
1735
1736Really fixed a bug in fsck to allow "fsck -As" to run interactive
1737fsck's. (For those people who like to do interactive fsck's in the
1738/etc/rc scripts!?!)
1739
1740Debugfs has a few new features: the rdump command, which will do a
1741recursive dump of a directory and all of its contents, and the lcd
1742command which does a local chdir (much like the ftp command of the
1743same name). In addition, the debugfs program and the open_filesystem
1744command now takes three new options: -b and -s, which allows the
1745blocksize and superblock location to be specified, and the -c option
1746which is used in catastrophic situations where the block group
1747descriptors are corrupt. If the -c option is specified, debugfs will
1748skip trying to read in the block and inode bitmaps.
1749
1750Debufs's lsdel command was fixed to handle bad blocks in the inode
1751table.
1752
1753A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
17544 digit years.
1755
1756General improvements in error messages
1757
1758 - Mke2fs prints a sane error message if the partition size is zero
1759 (usually because the partition table wasn't reread by the
1760 kernel due to the partition being busy), instead of "invalid
1761 argument passed to ext2 library while initializing superblock".
1762
1763 - Fsck now prints more self-explanatory message if an invalid UUID=
1764 or LABEL= specification is passed to it.
1765
1766UUID library changed to use the LGPL.
1767
1768Fixed a bug in the UUID library where very rapid calls to the
1769time-based UUID generator could cause duplicate UUID's to be returned.
1770This was not a problem for e2fsprogs, but it could be a problem for
1771other users of the library.
1772
1773Make the UUID library more robust in the face of missing or an
1774improper /dev/urandom or /dev/random files.
1775
1776Added some random portability fixes for Solaris.
1777
1778Some minor man page updates.
1779
1780Fixed a memory leak in the ss library.
1781
1782
1783Programmer's notes:
1784-------------------
1785
1786We now try to use lseek64 and open64 from the LFS if possible.
1787
1788The 3rd parameter in e2p's print_flags is now a flags word, instead of
1789a boolean option.
1790
1791The mark and unmark bitmap functions now return the previous state of
1792the bit that was being changed, which is useful for some speed
1793optimizations.
1794
1795The following functions have been added to enhance the badblocks list
1796handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
1797ext2fs_badblocks_equal.
1798
1799The ext2 header files now have the latest journalling fields to the
1800superblock.
1801
1802The ext2fs_mkdir function in libext2fs now properly backs out of error
1803conditions robustly.
1804
1805Cleaned up makefiles:
1806 - to cleanly compile with the -j flag.
1807 - so distclean removes all generated files.
1808 - so in case of an error while installing header files, the make aborts.
1809
1810Fix test_script so that it works correctly when compiling in the
1811source directory.
1812
Theodore Ts'o31d1d0c2001-05-11 05:15:06 +00001813The random UUID generation routine has been made slightly better in
1814the case where /dev/random doesn't exist. (Use of randomly-based UUID
1815is still not recommended if /dev/random doesn't exist, however; it's
1816better to use the time/ethernet MAC address UUID in this case.)
Theodore Ts'oab146762000-07-07 04:37:35 +00001817
1818Clean up the build process so it's more friendly in case of missing
1819directories.
1820
1821The ext2fs header file can now be #include'd into C++ programs.
1822
1823The e2p.h header file is now installed.
1824
1825Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
1826
1827
1828
Theodore Ts'o24ded091999-11-10 15:56:16 +00001829E2fsprogs 1.18 (November 10, 1999)
1830==================================
1831
1832Fix a core dumping bug in e2fsck if an imagic inode is present or
1833(more rarely) if the filesystem is badly corrupted enough that e2fsck
1834has to restart pass 1 processing. E2fsck now closes the filesystem
1835before freeing a large number of its data structures, so in the case
1836of future memory faults, at least the fixed filesystem will be fully
1837written out.
1838
1839If a filesystem doesn't support imagic inodes, and e2fsck discovers an
1840imagic inode, it will offer to clear the imagic flag.
1841
1842E2fsck will now offer to clear the immutable flag on special files
1843(device/socket/fifos) when running it in non-preen mode.
1844
1845E2fsck will now set the filetype when creating /lost+found, and when
1846connected orphaned inodes to /lost+found.
1847
1848Debugfs's ncheck and icheck commands now handles the case where there
1849are bad blocks in the inode table without bombing out.
1850
1851The badblocks list processing code has been made more efficiently for
1852appending a large number of (ordered) badblocks to the badblocks list.
1853
1854Some minor man page updates.
1855
1856Fsck now allows interactive e2fsck's when using fsck -As (not a common
1857mode, but some people like to do this in boot scripts for silly reasons).
1858
1859Programmer's notes:
1860-------------------
1861
1862The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
1863with the problem code convention.
1864
1865The badblocks list regression test program has been updated to work
1866with previously made API name changes.
1867
1868The ext2fs_free() command now uses the new badblocks API to avoid
1869using the compatibility layer.
1870
1871Added new regression test cases; the run_e2fsck test script now
1872supports the ability for a test case to run a prepratory command
1873before running e2fsck.
1874
Theodore Ts'o28e11941999-10-26 18:17:20 +00001875E2fsprogs 1.17 (October 26, 1999)
1876=================================
1877
1878Fixed nasty typo in fsck which caused parallelized fsck's to go into an
1879infinite loop.
1880
1881Fixed a bug in fsck where it used strncmp to compare a binary UUID,
1882thus potentially causing problems if a binary UUID contained a NULL
1883character.
1884
1885E2fsck now uses stricter checks for directory entries in pass 2:
1886zero-length filenames are not allowed; neither are 8 byte long
1887directory entries.
1888
1889The debugfs "dirty" command now clears the filesystem valid bit.
1890(Previously this just set the dirty-as-in-needs-writing-out-to-disk
1891bit in the in-core superblock image. The new functionality is more
1892what the user expects, and is more useful.)
1893
1894Added a debugging hook to test parallel fsck; if the environment
1895variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
1896will be checked in parallel when they normally would not be.
1897
1898Programmer's notes:
1899-------------------
1900
1901Fixed some #ifdef's for compilation under the Hurd OS.
1902
1903Fixed minor W2K compatibility problems.
1904
1905Fixed some miscellaneous GCC warnings.
1906
1907
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00001908E2fsprogs 1.16 (October 22, 1999)
1909=================================
1910
1911Fixed a race condition bug in fsck; when printing a progress bar, if
1912checking multiple filesystems in parallel, it was possible for fsck to
1913send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
1914handler, which would cause it to terminate with a signal 10.
1915
1916E2fsck now properly handles filesystems that have the
1917INCOMPAT_FILETYPE feature turned on. It can be used to convert a
1918filesystem into using or not using FILETYPE feature.
1919
1920E2fsck now properly handles filesystems that have the IMAGIC feature
1921turned on (this is used on Linux AFS servers).
1922
1923The mke2fs program now creates filesystems that have the filetype and
1924sparse_superblock features enabled by default, unless it is run on a
1925pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
1926so there is now a new flag -O which allows the user to specify with
1927which features she would like to create the filesystem; "mke2fs -O
1928none" will create a filesystsem compatible with 2.0 kernels.
1929
1930The tune2fs program now has a -O option which allows the user to set
1931and reset "safe" filesystem features. Currently, the only ones which
1932allows to be modified are the filetype and sparse_superblock features.
1933Note setting or clearing either feature will require running e2fsck on
1934the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
1935requires that there is enough free space on the filesystem for the
1936extra superblocks which will be created by e2fsck.)
1937
1938Debugfs can now set and print filesystem features in the superblock
1939using the "features" command. Dumpe2fs will print out the complete
1940set of features when listing the superblock.
1941
1942Dumpe2fs has new options -f (force) and -h (header-only).
1943
1944Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
1945message to come up. This could happen when decrementing or
1946incrementing a link count could result in an overflow.
1947
1948Fixed a bug in e2fsck where the block count on the lost+found
1949directory would not be properly incremented when the directory was
1950expanded to the point where an indirect block needed to be allocated.
1951
1952E2fsck now makes some additional sanity checks on the superblock to
1953avoid crashing or giving a memory allocation error if some of the
1954values in the superblock are unresonable (but the superblock otherwise
1955looks valid).
1956
1957Fixed a bug in e2fsck where a very badly corrupted filesystem might
1958require two passes to completely fix the filesystem. This happened if
1959an inode claimed blocks that was part of the filesystem metadata
1960(typically, when garbage was written into an inode table or indirect
1961block, since this kind of filesystem corruption normally doesn't
1962happen otherwise).
1963
1964On the Alpha, glibc declares st_flags although it isn't actually used;
1965the configure script was improved to detect this case so that
1966e2fsprogs can avoid using the non-functional stat field.
1967
1968The manual pages were updated to use a more consistent formatting
1969style consistent with standard Unix man pages. Mke2fs's man page
1970added documentation for a few previously undocumented options.
1971
1972Fixed minor display bugs in tune2fs and mke2fs.
1973
1974Programmer's notes:
1975-------------------
1976
1977Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
1978
1979Added features to parse and print feature strings into the e2p library.
1980(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
1981
1982ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
1983whose directory entries contain proper filetype information if the
1984filesystem supports it.
1985
1986ext2fs_link() now uses the low 3 bits of its flags parameter to pass
1987the directory entry filetype information. This is used to set the
1988directory entry filetype information if the filesystem supports it.
1989
1990Fixed a bug in ext2fs_expand_dir() where the block count in a
1991directory's inode would not be properly incremented when the directory
1992was expanded to the point where an indirect block needed to be
1993allocated.
1994
1995
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00001996E2fsprogs 1.15 (July 18, 1999)
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00001997==============================
Theodore Ts'o6d53db31999-07-03 20:52:21 +00001998
1999Add configuration checks so that e2fsprogs will compile cleanly on
2000Linux 2.3 kernels that have renamed i_version to i_generation.
2001
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002002E2fsck now prints a progress/completion bar (and not just a simple
2003spinner) if the -C0 option is requested or if it receives a SIGUSR1
2004signal. Fsck will automatically manage the (potentially muliple)
2005e2fsck processes to print completion bars if it is given a -C option,
2006with the right thing happening if multiple filesystems are being
2007checked in parallel.
2008
2009Mke2fs now has better automatic hueristics to determine the filesystem
2010parameters to be used for a particular filesystem. Added a new option
2011-T which allows the user to specify how the filesystem is to be used,
2012which helps mke2fs do a better job selecting the filesystem parameters.
2013
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002014Mke2fs now creates revision 1 filesystems by default, and with the
2015sparse superblock feature enabled. The sparse superblock feature is
Theodore Ts'o8a31ffe1999-10-23 03:33:15 +00002016not understood by Linux 2.0 kernels, so they will only allow read-only
2017mounts of filesystems with this sparse superblocks.
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002018
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002019Fix bug where if /dev/null couldn't be opened (should never happen),
2020e2fsck would hang in a tight loop.
2021
2022Make e2fsck handle the case where /lost+found isn't a directory.
2023
2024E2fsck now uses mallinfo if it exists to get accurate statistics about
2025its memory usage.
2026
2027Fix bug in e2fsck where it wouldn't check to see if a disconnected
2028inode had any problems before connecting it to /lost+found.
2029
2030Add check to e2fsck so it makes sure that total number of inodes in
2031the filesystem is a sane number.
2032
2033Fix fencepost error when clearing an the end of the block bitmap which
2034caused the last block in the bitmap not to get cleared.
2035
2036Cleaned up a number of messages in e2fsck:
2037 * The message "Group's #'s copy of the group descriptor..."
2038 was fixed so that the correct number would be displayed.
2039 * Added missing space in the "disk write-protected" error messsage
2040 * Cleaned up the error message printed when a non-interactive
2041 e2fsck needs to abort a check because the filesystem
2042 appears to be mounted.
2043
2044Added a new command-line utility, uuidgen, which will create and print
2045a UUID.
2046
2047Make debugfs's icheck command more robust by checking to make sure an
2048inode has valid blocks before interarting over the inode's blocks.
2049
2050UUID generation now uses a random-based scheme whenever possible to
2051prevent potential privacy problems.
2052
2053Man pages for all of the UUID functions in the lirbary were added.
2054
2055Fixed bug in fsck so it won't coredump if a filesystem not in
2056/etc/fstab is given to it.
2057
2058Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
2059that most of the other mount utilities understands.
2060
2061Mke2fs will make a filesystem even if it appears mounted if the force
2062option is given.
2063
2064Dumpe2fs has new command-line options which allow a filesystem expert
2065to specify the superblock and blocksize when opening a filesystem.
2066This is mainly useful when examining the remains of a toasted
2067filesystem.
2068
2069The badblocks program has been updated to display correctly on disks
2070with large block numbers.
2071
Theodore Ts'oe2a99be1999-07-19 15:48:08 +00002072The badblocks program no longer gives spurious errors when errors
2073occur on non-block boundaries, which is common if the blocksize is
2074larger than 1k.
2075
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002076Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
2077MKE2FS_SYNC environment variable is set. This is to work around a VM
2078bug in the 2.0 kernel. I've heard a report that a RAID user was able
Theodore Ts'oa39f3ef1999-07-20 02:02:40 +00002079to trigger it even using a 2.2 kernel, but hopefully it will not be
2080needed for most Linux 2.2 users.
Theodore Ts'o6d53db31999-07-03 20:52:21 +00002081
2082Fixed miscellaneous documentation and man pages.
2083
2084Programmer's notes:
2085-------------------
2086
2087Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
2088in e2fsck's pass1.c really should have been static.
2089
2090The return value of the uuid_compare() function was changed to make it
2091match with the convetions used by strcmp, memcmp, and Paul Leach's
2092UUID sample document.
2093
2094The "make depend" process has now been made more automated; it now
2095automatically word-wraps the dependencies, and only replaces source
2096Makefile.in if there has been a change in the dependencies. Also, a
2097top-level "make depend" now recurses through all the subdirectories
2098automatically.
2099
2100The Makefile in .../util has been changed so that subst is built using
2101the native C compiler during a cross-compilation, since the subst
2102program is only used during the build process. Also add an explicit
2103rule to build util/subst by cd'ing to the correct directory and
2104running Makefile.
2105
2106The man directories are defined in terms mandir, so that the configure
2107script can override the location of the manual pages.
2108
2109The config files have been updated to recognize new machine types for
2110both the i386 and alpha families.
2111
2112Fsck has been modified so that it will accurately create an
2113fsck_instance even when the noexecute flag is set. This allows for
2114accurate debugging of the fsck pass structure. Also, when the verbose
2115flag is given twice, fsck will print debugging information about when
2116fsck is waiting for jobs to finish.

Theodore Ts'o14790ed1999-01-12 23:32:52 +00002119E2fsprogs 1.14 (January 9, 1999)
2120================================
2121
2122Fix the fstab parsing code so that it can handle blank lines and
2123comment characters. Also, missing pass numbers need to be treated as
2124zero.
2125
2126Fixed a bug in e2fsck where under some circumstances (when e2fsck
2127needs to restart processing after fixing an egregious inconsistency)
2128it would try to access already freed memory.
2129
2130E2fsck now prints non-printable characters in directory entries and
2131pathnames using '^' and 'M-' notation.
2132
2133Fixed chattr so that it will ignore symbolic links when doing
2134recursive descent traversals. For both chattr and lsattr, no longer
2135print the version string unless the -V option is given.
2136
2137Allow the system administrator to directly specify the number of
2138inodes desired in the filesystem, for some special cases where this is
2139necessary.
2140
2141Fix portability problems so that e2fsprogs can be compiled under Linux
21421.2 systems and Solaris systems.
2143
2144Update the config.guess file with a more recent version that will
2145identify newer Linux platforms.
2146
2147Programmer's notes
2148------------------
2149
2150Ext2fs_read_inode and ext2fs_write_inode will now return an error if
2151an inode number of zero is passed to them.
2152
Theodore Ts'o556ad131998-12-19 08:10:58 +00002153E2fsprogs 1.13 (December 15, 1998)
2154==================================
2155
2156Fixed a bug in debugfs where an error messages weren't getting printed
2157when the ext2 library routines to read inodes returned errors in the
2158stat, cmri and rm commands.
2159
2160Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
2161provided, it won't create an inode table smaller than the minimum
2162number of inodes required for a proper ext2 filesystem.
2163
2164Fsck now parses the /etc/fstab file directly (instead of using
2165getmntent()), so that it can distinguish between a missing pass number
2166field and pass number field of zero. This caused problems for
2167diskless workstations where all of the filesystems in /etc/fstab have
2168an explicit pass number of zero, and fsck could not distinguish this
2169from a /etc/fstab file with missing pass numbers.
2170
2171E2fsck will create a /lost+found directory if there isn't one in the
2172filesystem, since it's safer to create the lost+found directory before
2173it's needed.
2174
2175Fixed e2fsck so that it would detect bogus immutable inodes which
2176happen to be sockets and FIFO files, and offer to clear them.
2177
2178If a filesystem has multiple reasons why it needs to be checked, and
2179one of the reasons is that it is uncleanly mounted, e2fsck will print
2180that as the reason why the filesystem is being checked.
2181
2182Cleaned up the output routines of mke2fs so that it doesn't overflow
2183an 80 column display when formating really big filesystems.
2184
2185Added a sanity check to e2fsck to make sure that file descriptors 0,
21861, 2 are open before opening the hard disk. This avoids a problem
2187where a broken program might exec e2fsck with those file descriptors
2188closed, which would cause disastrous results if the kernel returns a
2189file descriptor for the block device which is also used by FILE *
2190stdout.
2191
2192Fixed up the e2fsck progress reporting functions so that the values
2193reliably reach 100% at the completion of all of the e2fsck passes.
2194
2195Fixed minor documentation bugs in man pages and usage messages.
2196
2197Programmer's notes:
2198-------------------
2199
2200Fixed a number of lint warnings in the ext2fs library and potential
2201portability problems from other OS's header files that might define
2202CPP macros for names like "max" and "min".
2203
2204ext2fs_badblocks_list_add() has been made more efficient when it needs
2205to grow the bad blocks list.
2206
2207Fixed a bug in e2fsck which caused it to dereference a freed pointer
2208just before exiting.
2209
2210Fixed the substition process for generating the mk_cmds and compile_et
2211scripts so that they will work outside of the build tree.
2212
2213Add sanity check to e2fsck so that if an internal routine
2214(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
2215and causing a core dump. This should never happen, but...
2216
Theodore Ts'oa5696711998-07-09 05:38:07 +00002217E2fsprogs 1.12 (July 9, 1998)
Theodore Ts'o21d53851998-02-21 03:14:50 +00002218==================================
2219
2220E2fsprogs now works with glibc (at least with the version shipped wtih
2221RedHat 5.0). The ext2fs_llseek() function should now work even with
2222i386 ELF shared libraries and if llseek() is not present. We also
2223explicitly do a configure test to see if (a) llseek is in libc, and
2224(b) if llseek is declared in the system header files. (See standard
2225complaints about libc developers don't understand the concept of
2226compatibility with previous versions of libc.)
2227
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002228The ext2fs library now writes out the block group number in each of
2229the superblock copies. This makes it easier to automatically
2230determine the starting block group of the filesystem when the block
2231group information is trashed.
2232
2233Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
Theodore Ts'o101c84f1998-03-24 16:27:11 +00002234which means that e2fsprogs will ignore the high 8 bits of the
2235directory entry's name_len field, so that it can be used for other
2236purposes.
2237
2238Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
2239E2fsprogs will now support filesystems with 64-bit sized files.
2240
2241Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
2242
Theodore Ts'o21d53851998-02-21 03:14:50 +00002243Added new program "e2label", contributed by Andries Brouwer. E2label
2244provides an easy-to-use interface to modify the filesystem label.
2245
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002246Fixed bug so that lsattr -v works instead of producing a core dump.
2247
Theodore Ts'o21d53851998-02-21 03:14:50 +00002248Fixed a minor bug in mke2fs so that all groups with bad superblock
2249backup blocks are printed (not just the first one).
Theodore Ts'oa4b2d3c1998-04-03 16:12:25 +00002250
2251Mke2fs will check the size of the device, and if the user specifies a
2252filesystem size larger than the apparent size of the device it will
2253print a warning message and ask if the user wants to proceed.
2254
Theodore Ts'oc9833a61998-07-05 19:37:53 +00002255E2fsck has a new option -C, which sends completion information to the
2256specified file descriptor. For the most part, this is intended for
2257programs to use, although -C 0 will print a spinning character to the
2258stdout device, which may be useful for users who want to see something
2259happening while e2fsck goes about its business.
2260
Theodore Ts'o21d53851998-02-21 03:14:50 +00002261Fixed a bug in e2fsck which could cause a core dump when it needs to
2262expand the /lost+found directory, and sometimes the bitmaps haven't
2263been merged in. Also fixed a related bug where ext2fs_write_dir_block
2264was used to write out a non-directory block. (Which would be bad on a
2265non-Intel platform with byte swapping going on.)
2266
2267Fixed bug in e2fsck where it would print a "programming error" message
2268instead of correctly identifying where a bad block was in used when
2269the bad block was in a non-primary superblock or block group
2270descriptor. Also fixed a related bug when sparse superblocks are in
2271use and there is a bad block where a superblock or block group
2272descriptor would have been in a group that doesn't include a
2273superblock.
2274
2275Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
2276the block group descriptor table is corrupt, it was possible to try to
2277allocate a huge array, fail, and then abort e2fsck.
2278ext2fs_get_num_dirs() now sanity checks the block group descriptor,
2279and subsitutes reasonable values if the descriptors are obviously bogus.
2280
2281If e2fsck finds a device file which has the immutable flag set and the
2282i_blocks beyond the normal device number are non-zero, e2fsck will
2283offer to remove it, since it's probably caused by garbage in the inode
2284table.
2285
2286When opening a filesystem, e2fsck specially checks for the EROFS error
2287code, and prints a specific error message to the user which is more
2288user friendly.
2289
2290If the filesystem revision is too high, change the e2fsck to print
2291that this is either because e2fsck is out of date, or because the
2292superblock is corrupt.
2293
2294E2fsck now checks for directories that have duplicate '.' and '..'
2295entries, and fixes this corruption.
2296
2297E2fsck no longer forces a sync of the filesystem (with attendant sleep
2298calls) at all times. The ext2fs_flush() function now performs a sync
2299only if it needed to write data blocks to disk.
2300
2301Fixed a minor bug in e2fsck's pass1b's file cloning function, where
2302certain errors would not be properly reported.
2303
2304Updated and expanded a few points in the man pages which users
2305complained wheren't explicit enough.
2306
2307Added special case byte-swapping code if compiling on the PowerPC, to
2308accomodate the strange big-endian variant of the ext2 filesystem that
2309was previously used on the PowerPC port.
2310
2311
2312Programmer's notes:
2313-------------------
2314
2315Removed C++ keywords from the ext2fs libraries so that it could be
2316compiled with C++.
2317
2318E2fsck's internal organization has now been massively reorganized so
2319that pass*.c don't have any printf statements. Instead, all problems
2320are reported through the fix_problem() abstraction interface. E2fsck
2321has also been revamped so that it can be called as a library from a
2322application.
2323
2324Added new fileio primitives in libext2fs for reading and writing
2325files on an unmounted ext2 filesystem. This interface is now used by
2326debugfs.
2327
2328Added a new libext2fs function for mapping logical block numbers of
2329a file to a physical block number.
2330
2331Added a new libext2fs function, ext2fs_alloc_block(), which allocates
2332a block, zeros it, and updates the filesystem accounting records
2333appropriately.
2334
2335Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
2336sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
2337
2338The libext2fs functions now use a set of memory allocation wrapper
2339functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
2340instead of malloc, free, and resize. This makes it easier for us to
2341be ported to strange environments where malloc, et. al. aren't
2342necessarily available.
2343
2344Change the libext2fs fucntion to return ext2-specific error codes
2345(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
2346and depending on the existence of system error codes (such as EEXIST
2347and ENOENT).
2348
2349Renamed io.h to ext2_io.h to avoid collision with other OS's header
2350files.
2351
2352Add protection against ext2_io.h and ext2fs.h being included multiple
2353times.
2354
2355The types used for memory lengths, etc. have been made more portable.
2356In generla, the code has been made 16-bit safe. Added Mark
2357Habersack's contributed DOS disk i/o routines.
2358
2359Miscellaneous portability fixes, including not depending on char's
2360being signed.
2361
2362The io_channel structure has a new element, app_data, which is
2363initialized by the ext2fs routines to contain a copy of the filesystem
2364handle.
2365
2366ext2fs_check_directory()'s callback function may now return the error
2367EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
2368really do the checking, despite the presence of the callback function.
2369
2370
Theodore Ts'obc210071997-06-17 05:41:36 +00002371E2fsprosg 1.11 (June 17, 1997)
2372==============================
2373
2374Fixed e2fsck to detect (previously ignored) conflicts between the
2375superblock or block group descriptors and block bitmaps, inode
2376bitmaps, and inode tables.
2377
2378Fixed bug in e2fsck so that when the message printed out when a block
2379or inode bitmap conflicts with other data, it has the correct group
2380number.
2381
2382Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
2383to badblocks. This meant that not all of the filesystem was being
2384tested for bad blocks!
2385
2386Fixed an array boundary overrun case which cropped up in
2387ext2fs_badblocks_list_test when a user tried running "mke2fs -c
2388-b 4096".
2389
2390Adjusted the number of columns printed by mke2fs when displaying the
2391superblock backups to avoid running over 80 columns when making a
Theodore Ts'o21d53851998-02-21 03:14:50 +00002392really big filesystem.
Theodore Ts'obc210071997-06-17 05:41:36 +00002393
2394Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
2395dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
2396fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
2397
2398Programmer's notes:
2399-------------------
2400
2401Fixed install rule in lib/ss so that ss_err.h is actually getting
2402installed.
2403
2404Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
2405bassed back to the caller.
2406
2407Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
2408setting the current inode number (which meant this function wasn't
2409working at all).
2410
2411Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
2412blocks in the bitmap when increasing the size of the bitmap.
2413
2414Changed the initial number of blocks allocated by ext2fs_init_dblist()
2415to be more realistic.
2416
2417Added a new function ext2fs_allocate_group_table, which sets up the
2418group descriptor information (and allocates inode and block bitmaps,
2419and inode tables for a particular group). The function was created by
2420factoring out code form ext2fs_allocate_tables().
2421
2422Added a new function ext2fs_move_blocks which takes a bitmap of the
2423blocks to be moved, and moves them to another location on the
2424boardboard.
2425
2426Make the unix_io channel's io_channel_flush implementation calls sync()
2427to to flush the kernel buffers to disk.
2428
2429Added a new function ext2fs_dblist_count returns the number of
2430directory blocks in dblist.
2431
2432
Theodore Ts'oae851481997-04-29 18:13:24 +00002433E2fsprogs 1.10 (April 24, 1997)
2434===============================
2435
2436Mke2fs once again defaults to creating revision #0 filesystems, since
2437people were complaining about breaking compatibility with 1.2 kernels.
2438Warning messages were added to the mke2fs and tune2fs man pages that
2439the sparse superblock option isn't supported by most kernels yet (1.2
2440and 2.0 both don't support parse superblocks.)
2441
2442Added new flag to mke2fs, -R <raid options>, which allows the user to
2443tell mke2fs about the RAID configuration of the filesystem. Currently
2444the only supported raid option is "stride" which specifies the width
2445of the RAID stripe.
2446
2447Fixed bug in e2fsck where pass1b would bomb out if there were any
2448blocks marked bad in the inode table.
2449
2450Fixed rare bug in mke2fs where if the user had a very unlucky number
2451of blocks in a filesystem (probability less than .002) the resulting
2452filesystem would be corrupt in the last block group.
2453
2454Fixed bug where if e2fsck tried to allocate a block to fix a
2455filesystem corruption problem and the filesystem had no free blocks,
2456ext2fs_new_block() would loop forever.
2457
2458The configure script now checks explicitly to see if "-static" works,
2459since that can't be assumed to be true --- RedHat doesn't install
2460libc-static by default.
2461
2462Fixed bug in libext2's block iterator functions where under some
2463cirmcustances, file with holes would cause the bcount parameter to the
2464callback function to be incorrect. This bug didn't affect any of
2465e2fsprogs programs, but it was discovered by Paul Mackerras, the
2466author of the PPC boot loader.
2467
2468Removed use of static variables to store the inode cache in libext2fs.
2469This caused problems if more than one filesystem was accessed via
2470libext2fs (static variables in libraries are generally a bad idea).
2471Again, this didn't affect e2fsprogs programs, but it was discovered by
2472Paul Mackerras.
2473
2474Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
2475will compile cleanly with 1.2.13 kernels (even with a.out shared
2476libraries!)
2477
2478Programmer's notes:
2479-------------------
2480
2481Added new functions to duplicate an ext2 filesystem handle, and its
2482associated substructure. New functions: ext2fs_dup_handle(),
2483ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
2484Other structures, such as the io_channel and the inode_cache, now have
2485a ref count so that they only get freed when they are no longer used
2486by any filesystem handle. (These functions were added as part of the
2487development effort for an ext2 resizer).
2488
Theodore Ts'o2ecc6fe1997-04-29 17:57:00 +00002489E2fsprogs 1.09 (April 14, 1997)
2490===============================
2491
2492Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
2493accidentally introduced in the 1.08 release. The overhead calculation
2494was accidentally removed, which caused ext2fs_initialize() to not
2495notice when the filesystem size needed to be adjusted down because
2496there wasn't enough space in the last block group.
2497
2498Fixed bug in version parsing library routine; it was always parsing
2499the library version string, instead of using the passed-in string.
2500
2501Clarified chattr man page.
2502
Theodore Ts'o24757fa1997-04-29 17:39:27 +00002503E2fsprogs 1.08 (April 10, 1997)
2504===============================
2505
2506E2fsck 1.07 was very slow when checking very large filesystems with a
2507lot of files that had hard links (i.e., news spools). This was fixed
2508by seriously revamping the icount abstraction. Added a formal test
2509suite for the icount abstraction.
2510
2511Debugfs now has a "-l" option to the "ls" command, which lists the
2512inode number, permissions, owner, group, size, and name of the files
2513in the directory.
2514
2515Fix a bug in e2fsck where when a directory had its blocks moved to
2516another location during the pass 1b processing, the directory block
2517list wasn't updated, so pass 2 wouldn't check (and correct) the
2518correct directory block.
2519
2520E2fsck will now treat inodes which contain blocks which are claimed by
2521the filesystem metadata by treating them as multiply claimed blocks.
2522This way, the data in those blocks can be copied to a new block during
2523the pass 1b--1d processing.
2524
2525E2fsck will attempt to determine the correct superblock number and
2526display it in the diagnostic and warning messages if possible.
2527
2528Add support for a new (incompatible) feature, "sparse_super". This
2529feature reduces the number of blocks which contain copies of backup
2530superblocks and block group descriptors. (It is only an incompatible
2531feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
2532support a new -s option; e2fsck will recognize filesystems built with
2533this feature turned on.
2534
2535E2fsck now checks the library to make sure is the correct version,
2536using new library functions. (This helps to diagnose incorrectly
2537installed e2fsprogs distributions.)
2538
2539Dumpe2fs now prints more information; its now prints the the
2540filesystem revision number, the filesystem sparse_super feature (if
2541present), the block ranges for each block group, and the offset from
2542the beginning of the block group.
2543
2544Mke2fs now distributes the inode and block bitmap blok so that the
2545won't be concentrated in one or two disks in RAID/striping setups.
2546Also, if the user chooses a 2k or 4k block group, mke2fs will try to
2547choose the largest blocks per group that be chosen. (For 2k blocks,
2548you can have up to 16384 blocks/group; for 4k blocks, you can have up
2549to 32768 blocks/group.) Previously mke2fs would not allow
2550specification of more than 8192 blocks per group, even if you were
2551using a 2k or 4k block group.
2552
2553Programmer's notes:
2554-------------------
2555
2556Added a new function ext2fs_create_icount2() which takes a "hint"
2557argument. This hint argument presets the icount array with the list
2558of inodes which actually need to be in the icount array. This really
2559helps to speed up e2fsck.
2560
2561Added a new function ext2fs_icount_validate() which checks the rep
2562invariant for the icount structure. This is used mostly for testing.
2563
2564The error mesasage given when a bad inode number is passed to
2565test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
2566EXT2FS_UNMARK_ERROR).
2567
2568Added a new function ext2fs_set_dir_block which sets the block of a
2569dblist entry, given the directory inode and blockcnt.
2570
2571Added a new function ext2fs_get_library_version() which returns the
2572current library version, and ext2fs_parse_version_string() which
2573returns a version number based on a e2fsprogs version string.
2574
2575The icount functions will return EINVAL if the passed in inode number
2576is out of bounds.

2579==============================
2580
2581E2fsck is now uses much less memory when checking really large
2582filesystems (or rather, filesystems with a large number of inodes).
2583Previously a filesystem with 1 million inodes required 4 megabytes of
2584memory to store inode count statistics; that storage requirement has
2585now been reduced to roughly half a megabyte.
2586
2587E2fsck can now properly deal with bad blocks appearing inside the
2588inode table. Instead of trying to relocate the inode table (which
2589often failed because there wasn't enough space), the inodes in the bad
2590block are marked as in use.
2591
2592E2fsck will automatically try to use the backup superblocks if the
2593primary superblocks have a bad magic number or have missing meta-data
2594blocks (or meta-data blocks which are out of range).
2595
2596E2fsck's pass 3 has been made more efficient; most noticeable on
2597filesystems with a very large number of directories.
2598
2599Completely revamped e2fsck's system of printing problem reports. It
2600is now table driven, to make them more easily customizeable and
2601extendable. Error messages which can be printed out during preen mode
2602are now one line long.
2603
2604Fixed e2fsck's filesystem swapping code so that it won't try to swap
2605fast symbolic links or deleted files.
2606
2607Fixed e2fsck core dumping when fixing a filesystem which has no
2608directories (not even a root directory).
2609
2610Added a check to e2fsck to make sure that the length of every
2611directory entry is a multiple of 4 (since the kernel complains if it
2612isn't).
2613
2614Added a check to e2fsck to make sure that a directory entry isn't a
2615link to the root directory, since that isn't allowed.
2616
2617Added a check to e2fsk to now make sure the '.' and '..' directory
2618entries are null terminated, since the 2.0 kernel requires it.
2619
2620Added check to write_bitmaps() to make sure the superblock doesn't get
2621trashed if the inode or block bitmap is marked as being block zero.
2622
2623Added checking of the new feature set fields in the superblock, to
2624avoid dealing with new filesystem features that this package wasn't
2625set up to handle.
2626
2627Fixed a fencepost error in ext2fs_new_block() which would occasionally
2628try to allocate a block beyond the end of a filesystem.
2629
2630When the UUID library picks a random IEEE 802 address (because it
2631can't find one from a network card), it sets the multicast bit, to
2632avoid conflicting with a legitimate IEEE 802 address.
2633
2634Mke2fs now sets the root directory's owner to be the real uid of the
2635user running mke2fs. If the real uid is non-zero, it also sets
2636the group ownership of the root directory to be the real group-id of
2637the user running mke2fs.
2638
2639Mke2fs now has more intelligent error checking when it is given a
2640non-existent device.
2641
2642When badblocks is given the -vv option, it now updates the block that
2643it is currently testing on every block.
2644
2645Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
2646currently correctly if PATH wasn't already set.
2647
2648Shared libraries now built with dependencies. This allows the shared
2649library files to be used with dlopen(); it also makes the transition
2650to libc 6 easier, since ld.so can tell which libc a particular shared
2651library expects to use.
2652
2653Programmer's notes:
2654-------------------
2655
2656Added new abstraction (defined in dblist.c) for maintaining a list of
2657blocks which belongs to directories. This is used in e2fsck and other
2658programs which need to iterate over all directories.
2659
2660Added new functions which test to see if a contiguous range of blocks
2661(or inodes) are available. (ext2fs_*_bitmap_range).
2662
2663Added new function (ext2_inode_has_valid_blocks) which returns true if
2664an inode has valid blocks. (moved from e2fsck code).
2665
2666Added new function (ext2fs_allocate_tables) which allocates the
2667meta-data blocks as part of initializing a filesystem. (moved from
2668mke2fs code).
2669
2670Added a new I/O manager for testing purposes. It will either allow a
2671program to intercept I/O requests, or print debugging messages to
2672trace the activity of a program using the I/O manager.
2673
2674The badblocks_list functions now store the bad blocks in a sorted
2675order, and use a binary search to speed up badblocks_list_test.
2676
2677The inode scan function ext2fs_get_next_inode() may now return a soft
2678error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
2679those cases where part of an inode table is missing or there is a bad
2680block in the inode table.
2681
2682Added a new function (ext2fs_block_iterate2) which adds new arguments to
2683the callback function to return a pointer (block and offset) to the
2684reference of the block.
2685
2686Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
2687application to jump to a particular block group while doing an inode
2688scan.
2689
2690The badblocks list functions were renamed from badblocks_* to
2691ext2fs_badblocks_*. Backwards compatibility functions are available
2692for now, but programs should be modified to use the new interface.
2693
2694Some of the library functions were reorganized into separate files to
2695reduce the size of some programs which statically link against the
2696ext2 library.
2697
2698Put in some miscellaneous fixes for the Alpha platform.
2699

2701E2fsprogs 1.06 (October 7, 1996)
2702================================
2703
2704Fixed serious bug in e2fsck: if the block descriptors are bad, don't
2705smash the backup copies in ext2fs_close(). (The problem was that when
2706e2fsck -p discovered the problem, while it was closing the filesystem
2707and exiting, it was also blowing away the backup superblocks on the
2708disk, which was less than friendly.) We now make it the case that we
2709only write out the backup superblock and the back block descriptors if
2710the filesystem is completely free from problems.
2711
2712Fixed a bug in block_interate in the lib/ext2fs library which caused
2713e2fsck to fail on GNU Hurd-created filesystems.
2714
2715Add support for Linux/FT's bootloader, which actually uses
2716EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
2717to clear the inode.
2718
2719Add support for the "A" (no atime update) attribute. (Note: this
2720attribute is not yet in production kernels.)
2721
2722The test suite is not automatically run when doing a "make all" from
2723the top level directory. Users should manually run "make check" if
2724they wish to run the test suite.
2725
2726Upon a preenhalt(), make the printed message more explicit that
2727running e2fsck "MANAULLY" means without the -p or -a options.
2728
2729In e2fsck, if a disconnected inode is zero-length, offer to clear it
2730instead of offering to connect it to lost+found.
2731
2732In e2fsck, if a filesystem was just unmounted uncleanly, and needs
2733e2fsck to be run over it, change e2fsck to explicitly display this
2734fact.
2735
2736For dumpe2fs and e2fsck, cause the -V option to print out which
2737version of the ext2fs library is actually getting used. (This will
2738help detect mismatches of using a 1.06 utility with a 1.05 library,
2739etc.)
2740
2741Programmers' notes:
2742-------------------
2743
2744EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
2745the naming convention.
2746
2747In ext2fs_initialize(), make sure the description for the inode bitmap
2748is correctly initialize.
2749
2750Fixed minor type typo in ext2fs_allocate_generic_bitmap();
2751
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002752E2fsprogs 1.05 (September 7, 1996)
2753==================================
2754
2755Add support for new fields in the ext2 superblock --- volume name,
2756volume UUID, and last mounted field. Dumpe2fs displays these fields,
2757tune2fs and mke2fs allows you to set them. E2fsck will automatically
2758generate a UUID for those volumes that don't have them.
2759
2760Put in support for e2fsck to recognize HURD specific ext2 features ---
2761most notably, the translator block. The e2fsprogs tools will now use
2762the creator_os field in the superblock to correctly handle different
2763OS-specific variants of the ext2 filesystem.
2764
2765E2fsck now fixes inodes which have a the deletion time set, but which
2766have a non-zero i_link_count field by offering to clear the deletion
2767time. Previously e2fsck assumed that the inode was deleted (per 0.3c
2768ext2 kernel behavior) and offered to unlink the file.
2769
2770If e2fsck sets the clean bit, but nothing else, set the exit code
2771FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
2772set the filesystem valid bit when it was previously cleared. :-) This
2773was needed to make the HURD fsck driver happy.
2774
2775If the user refuses to attach an unattached inode, e2fsck will no
2776longer set the inode's link count. Otherwise, the inode would end up
2777getting marked as unused, which might cause loss of data later.
2778
2779Make the message issued by e2fsck when the superblock is corrupt less
2780confusing for users. It now mentions that another reason for the
2781"corrupt superblock" message might be that the partition might not be
2782an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
2783
2784Make the libext2 library more robuest so that e2fsck won't coredump on
2785an illegal superblock where the blocksize is zero. (f_crashdisk is
2786the test case).
2787
2788By default, create filesystems where the default checkinterval is 6
2789months (180 days). Linux servers can be robust enough that 20 reboots
2790can be a long, long time.
2791
2792Added configure flag --enable-old-bitops, which forces the bitops to
2793use the old (native) bitmask operations. By default on the sparc
2794platform, the standard ext2 bit ordering is now used.
2795
2796Added a new feature to e2fsck to byte-swap filesystems; this can be
2797used to convert old m68k filesystems to use the standard byte-order
2798storage for the superblock, inodes, and directory blocks. This
2799function is invoked by using the '-s' option to e2fsck.
2800
2801Debugfs's "dump" command has been enhanced so that it writes out the
2802exact size of the file so that the nulls at the end of the file are
2803eliminated. The command also accept a new "-p" option which will
2804attempt preserve to preserve the ownernship, permissions, and
2805file modification/access times.
2806
2807Debugfs has two new options, -f and -R. The -R option allows the user
2808to execute a single debugfs command from the command line. The -f
2809option allows the user to specify a "command file" containing debugfs
2810commands which will get executed.
2811
2812Dumpe2fs now pretty prints the check interval, instead of just
2813printing the check interval as a number of seconds.
2814
2815Fix bugs in debugfs: the params command when no filesystem is opened
2816no longer causes a core dump. It is now possible to unlink a file
2817when a pathame containing a '/' is specified.
2818
2819Tune2fs has a new -C option which sets the number of times the
2820filesystem has been mounted.
2821
2822Fix the chattr '-v' option so that it actually works. Chattr was
2823being buggy about the -v option parsing.
2824
2825Programmers' notes:
2826-------------------
2827
2828The directory lib/uuid contains a set of library routines to generate
2829DCE compatible UUIDs.
2830
2831Extended ext2fs_namei() to handle symbolic links. Added new function
2832ext2fs_nami_follow() which will follow last symbolic link in the case
2833where the pathname points to a sym link.
2834
2835The ext2fs_block_iterate function will now return the HURD translator
2836block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
2837iterator to return data blocks only. The ext2fs.h file now defines
2838constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
2839BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
2840count field of the iterator callback function.
2841
2842The test script driver now takes an optional second argument, which is
2843the test case to be run. This allows you to run a test case without
2844needing to run the entire test suite.
2845
2846On Linux ELF systems, install the .so files in the correct places
2847(/usr/lib). The .so files must be stored in the same directory as the
2848.a files.
2849
2850Fixed miscellaneous HURD compilation issues with header file being
2851included in the right order.
2852
2853Fixed debugfs so that it resets optind to zero, not one, since setting
2854optind to zero is more correct.
2855
2856
Theodore Ts'oa4d09611997-04-29 14:28:00 +00002857E2fsprogs 1.04 (May 16, 1996)
2858=============================
2859
2860First "official" (1.03 was a limited release only) to support building
2861e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
2862kernels).
2863
2864This package includes a RPM specs file, that it can be built using the
2865RedHat Package Manager.
2866
2867E2fsck now prints a hint that if there are lots of incorrectly located
2868inode bitmaps, block bitmaps, and inode table blocks, the user might
2869want to try using e2fsck -b 8193 first, to see if that fares any
2870better.
2871
2872For ext2 filesystem written with the hurd, debugfs will now print out
2873the translator field when printing an inode structure.
2874
2875Lots of miscellaneous linking/installation cleanups:
2876
2877 Libraries are now linked using a relative pathname, instead of
2878 relying on -L working correct. It doesn't, in many cases, including
2879 current versions of GNU ld. This guarantees that the build tree is
2880 linking with the right libraries, instead of the ones installed in
2881 /usr/lib.
2882
2883 Header files, man pages, and the et/ss shell scripts are now
2884 generated using a custom substitution script, instead of relying on
2885 the configure script. This prevents needless recompilation of
2886 files; in addition, the custom substitution script is much faster.
2887
2888 e2fsck may now be linked dynamically, by using the
2889 --enable-dynamic-e2fsck flag to configure. This is not recommended,
2890 since it increases e2fsck's dependence on other files, but some
2891 people need to save disk space, and other critical programs on their
2892 systems were being linked dynamically anyway.
2893
2894 Programs such as fsck which didn't need to be linked against
2895 libext2fs (or mke2fs which didn't need to be linked against libe2p)
2896 only link against libraries they actually need. Otherwise, those
2897 programs would require the presense of libraries that otherwise
2898 could be removed from a rescuse diskette.
2899
2900 The ss include files are now installed correctly so they can
2901 actually be used by another package.
2902
2903 If the profiling libraries are built, they are now installed on a
2904 "make install-libs".
2905
2906
Theodore Ts'o7f88b041997-04-26 14:48:50 +00002907E2fsprogs 1.03 (March 27, 1996)
2908===============================
2909
2910Change the m68k bit numbering for bitmasks to match the bit numbering
2911used by all other ext2 implementations. (This change was requested by
2912the m68k kernel development team.)
2913
2914Support (in-development) filesystem format revision which supports
2915(among other things) dynamically sized inodes.
2916
2917Fixed a bug in the ext2 library so that an intelligent error is
2918returned if mke2fs is run with a ridiculously small number of blocks
2919for a partition.
2920
2921Fixed a bug in the ext2 library which required that the device be
2922openable in read/write mode in order to determine its size. This
2923caused e2fsck -n to require read/write access when it was not
2924previously necessary.
2925
2926Fixed a bug in e2fsck which casued it to occasionally fail the test
2927suite depending on which version of the floating point library it was
2928using.
2929
2930Fixed a bug in e2fsck so that it now halts with a fatal error when
2931certain superblock consistency checks fail. Previously it continued
2932running e2fsck, with some potential confusing/damaging consequences.
2933
2934Added new flag to fsck which allows the root to be checked in parallel
2935with other filesytems. This is not the safest thing in the world to
2936do, but some system administrators really wanted it.
2937
Theodore Ts'ofc6d9d51997-04-29 14:51:31 +00002938Fixed -Wall flames in lib/ss.
2939
Theodore Ts'o74becf31997-04-26 14:37:06 +00002940
2941E2fsprogs 1.02 (January 16, 1996)
2942=================================
2943
2944Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
2945
2946Change e2fsck to print statistics of how many non-contiguous files are
2947on the system. Note that a file which is larger than 8k blocks, it is
2948guaranteed to be non-contiguous.
2949
2950In mke2fs, print a warning message if a user tries to format a whole
2951disk (/dev/hda versus /dev/hda1). If a user really wants to format a
2952whole disk, the -F (force) option forces mke2fs to format a whole disk
2953as a filesytem.
2954
2955Fix a bug in fsck where in some cases it might start checking
2956partitions in the next pass before it finishes checking partitions in
2957the current pass. This still won't cause two partitions on the same
2958disk will be checked, so it's rarely a problem in real life.
2959
2960Patch lsattr so that it won't hang when checking a named pipe.
2961
2962Minor compilation fixes:
2963 * Fix the order of libraries that were linked in debugfs.
2964 * Allow the sources to be compiled with -ansi turned on.
