1 2007-05-22 Theodore Tso <tytso@mit.edu>
3 * message.c (expand_inode_expression, expand_percent_expression):
4 Fix gcc -Wall warnings on 64-bit systems.
6 * pass1.c (e2fsck_pass1_check_device_inode): Mark the fs parameter
8 (e2fsck_setup_tdb_icount): Use profile_get_uint() function
9 for reading the threshold. Remove unused variables.
11 * dirinfo.c (setup_tdb): Use the profile_get_uint() function for
12 reading the threshold.
13 (setup_db): Declare it as static
14 (setup_tdb): #include uuid.h since we use a uuid function
15 (e2fsck_get_dir_info, e2fsck_dir_info_iter_begin): Remove
17 (e2fsck_dir_info_iter_end): Mark the ctx parameter as
20 * profile.h, profile.c (profile_get_uint): New function which
21 returns an unsigned integer.
23 2007-05-08 Kalpak Shah <kalpak@clusterfs.com>
25 * pass1.c (check_ea_in_inode): Remove check that requires in-inode
26 EA's to be sorted, since they don't have to be.
28 2007-05-08 Theodore Tso <tytso@mit.edu>
30 * message.c (expand_inode_expression): Use inode_uid() and
31 inode_gid() macros when printing the uid/gid.
33 2007-04-18 Theodore Tso <tytso@mit.edu>
35 * e2fsck.conf.5.in (apply): Fix minor typo.
37 2007-04-14 Theodore Tso <tytso@mit.edu>
39 * pass2.c (e2fsck_process_bad_inode): Remove special kludge that
40 dealt with long symlinks on big endian systems. It turns
41 out this was a workaround to a bug described in Red Hat
42 Bugzilla #232663, with an odd twist. See comment #12 for
45 * pass1.c, pass2.c, util.c: Add better ehandler_operation()
46 markers so it is clearer what e2fsck was doing when an I/O
49 *pass1.c (check_is_really_dir): Fix a typo which could cause
50 e2fsck to throw an I/O error while doubling checking
51 whether or not a special device file was really an inode.
52 Also, don't do this tests on symbolic links since for
53 filesystems with a large numbers of symlinks it could
54 degrade performance and increases the risk for false
57 2007-04-10 Jim Garlick <garlick@llnl.gov>
59 * pass1b.c (search_dirent_proc): if a file has multiple hard
60 links, e2fsck pass1c search_dirent_proc() doesn't maintain
61 its count properly and may return DIRENT_ABORT before it
62 has found containing directories for all inodes sharing
65 2007-04-06 Theodore Tso <tytso@mit.edu>
67 * e2fsck.conf.5.in: Update man page to document the scratch_files
70 * dirinfo.c: If e2fsck.conf configures a scratch_files directory
71 which is available, and the number of directories exceeds
72 scratch_files.numdirs_threshold, then try to use the tdb
73 library to store the directory information abstraction.
74 This allows us to check very large filesystems without
75 needing as much physical memory.
77 * e2fsck.h, pass1.c, pass2.c: If e2fsck.conf configures a
78 scratch_files directory which is available, and the number
79 of directories exceeds scratch_files.numdirs_threshold,
80 then try to use the tdb library to store the inode count
81 abstraction. This allows us to check very large
82 filesystems without needing as much physical memory.
84 2007-04-04 Theodore Tso <tytso@mit.edu>
86 * dirinfo.c, pass2.c, pass3.c, rehash.c, e2fsck.h: Change the
87 iterator abstraction and replace e2fsck_get_dir_info()
88 with e2fsck_dir_info_{set,get}_{parent,dotdot} so that we
89 can support an on-disk dirinfo implementation. This
90 allows e2fsck to check very large filesystems on systems
91 with smaller amounts of memory and/or address space.
93 * pass1.c (check_ext_attr): Make sure the region variable is
94 initialized to zero to avoid checking and then freeing an
95 uninitialized pointer if there is a corrupted EA block.
97 2007-03-31 Theodore Tso <tytso@mit.edu>
99 * pass1.c (e2fsck_pass1, check_is_really_dir): Check for an edge
100 condition where the mode of a directory is incorrect, and
101 looks like a special device, but it is really a directory.
102 We can't do this for regular files because of the
103 performance hit, but this will catch directories which
104 have their i_mode bits mutated so they looks like a
107 * problem.c, problem.h (PR_1_TREAT_AS_DIRECTORY): New problem code
109 * message.c (expand_percent_expression): Add support for %It, which
110 will print the type of the inode.
112 * pass3.c (fix_dotdot_proc): Fix the filetype of the '..' entry to
113 be EXT2_FT_DIR. (Addresses Lustre BZ #11645)
115 * pass1.c (e2fsck_pass1_check_device_inode): Don't assume that a
116 special device is bogus just because i_blocks is non-zero.
117 The i_blocks field could get adjusted later, and if this
118 happens it will confuse the e2fsck_process_bad_inode() in
119 pass 2. In practice true garbage inodes will have random
120 non-zero values in i_blocks[4..15], so there's no point
121 doing the check for an illegal i_blocks value.
123 2007-03-28 Theodore Tso <tytso@mit.edu>
125 * pass1.c (e2fsck_pass1, check_ext_attr),
126 pass5.c (check_block_bitmaps, check_inode_bitmaps),
127 pass4.c (e2fsck_pass4), swapfs.c (swap_inodes),
128 journal.c (e2fsck_get_journal),
129 unix.c (parse_extended_opts): Fix memory leaks
131 2007-03-21 Theodore Tso <tytso@mit.edu>
133 * profile.c (profile_open_file): Fix memory leak if malloc() fails
134 while setting up the profile data structure.
136 2007-03-19 Theodore Tso <tytso@mit.edu>
138 * pass3.c (check_directory): Add error check in case
139 e2fsck_get_dir_info() returns NULL. Also fix another
140 error check for e2fsck_get_dir_info() to display the
141 correct inode number in case of this internal (should
144 * pass1b.c (clone_file): Fix a coverity-found bug; add error
145 checking in case dict_lookup() returns NULL when looking up
146 an block or inode record after cloning the EA block.
148 * profile.c (profile_init, get_dirlist): Fix bug where if a
149 profile directory is completely empty, the profile library
152 2006-12-22 Theodore Tso <tytso@mit.edu>
154 * unix.c (PRS, main): Use the new {add,remove}_error_table comerr
155 interfaces instead of initialize_*_error_table.
157 2006-11-14 Theodore Tso <tytso@mit.edu>
159 * unix.c (PRS): Always allocate the replacement PATH environment
160 passed to putenv() to avoid gcc -Wall warning.
162 * pass1.c, pass2.c, profile.c, super.c: Remove unused variables
163 and fixed signed vs unsigned and const gcc -Wall warning.
165 * message.c (expand_inode_expression): Fix const gcc -Wall warning.
167 * journal.c (e2fsck_fix_ext3_journal_hint): Remove unusued
168 variables retval and problem.
170 2006-11-11 Theodore Tso <tytso@mit.edu>
172 * super.c (e2fsck_fix_dirhash_hint, check_super_block): If neither
173 the signed or unsigned dirhash hint, set it based on
174 default signed vs. unsigned character type in use by the
177 * problem.c, problem.h (PR_0_DIRHASH_HINT): Add new problem code.
179 * pass2.c (check_dir_block), rehash.c (fill_dir_block): Check the
180 superblock flags to determine whether to use the signed or
181 unsigned version of the hash should be used.
183 * problem.c, problem.h (PR_2_BLOCKS_HI_ZERO): Add new problem code.
185 * pass1.c (e2fsck_pass1), pass2.c (e2fsck_process_bad_inode):
186 Replace check for l_i_frag and l_i_fsize with one for
189 2006-11-08 Theodore Tso <tytso@mit.edu>
191 * badblocks.c (read_bad_blocks_file): Change the last_block
192 argument passed to the badblocks program to be consistent
193 with the change to badblocks.
195 2006-10-21 Theodore Tso <tytso@mit.edu>
197 * pass2.c (parse_int_node): Don't core dump if there is a corrupt
198 htree interior node. If the block number is larger than
199 the number of blocks in the directory, don't write past
200 the end of malloc'ed memory. (Addresses SourceForge Bug:
203 2006-10-02 Theodore Tso <tytso@mit.edu>
205 * e2fsck.conf.5.in: Minor correction to man page.
206 (Addresses Debian bug #369761)
208 2006-10-01 Theodore Tso <tytso@mit.edu>
210 * Makefile.in (DEPLIBBLKID): Use DEPLIBBLKID not LIBBLKID to
211 define the dependencies used by the blkid library.
213 2006-08-30 Eric Sandeen <esandeen@redhat.com>
215 * pass1.c (handle_bad_fs_blocks): use blk_t, not int for first_block.
217 2006-08-30 Eric Sandeen <esandeen@redhat.com>
219 * unix.c (show_stats): use ext2_ino_t for inode containers.
221 2006-08-30 Eric Sandeen <esandeen@redhat.com>
223 * pass1.c (new_table_block, handle_fs_bad_blocks):
224 * super.c (check_super_block):
225 Use new inlines to calculate group first & last blocks.
227 2006-08-30 Eric Sandeen <esandeen@redhat.com>
229 * e2fsck.h (e2fsck): Use unsigned types for filesystem counters.
230 * emptydir.c (add_empty_dirblock):
232 * unix.c (show_stats, check_if_skip): Fix printf formats.
234 2006-08-30 Eric Sandeen <esandeen@redhat.com>
236 * pass1.c (handle_fs_bad_blocks): Remove unused variables.
238 2006-08-30 Eric Sandeen <esandeen@redhat.com>
240 * pass1b.c (check_if_fs_block): Change block group loop to use
241 a common pattern of first_block/last_block, etc.
243 * super.c (check_super_block): Avoid overflows when iterating over
244 group descriptors on very large filesystems
246 2006-08-30 Theodore Tso <tytso@mit.edu>
248 * pass5.c (check_inode_bitmaps, check_inode_end, check_block_end):
249 * pass4.c (e2fsck_pass4): Fix potential overflow problems when the
250 number of blocks is close to 2**31.
252 2006-08-29 Theodore Tso <tytso@mit.edu>
254 * super.c (release_inode_blocks): Fix silly spelling error.
255 (Addresses SourceForge Bug: #1531372)
257 2006-05-29 Theodore Tso <tytso@mit.edu>
259 * pass1b.c: Add missing semicolon when HAVE_INTPTR_T is not defined
261 2006-05-22 Theodore Tso <tytso@mit.edu>
263 * e2fsck.8.in: Fixed spelling mistake. (Addresses Debian Bug:
266 2006-05-14 Theodore Tso <tytso@mit.edu>
268 * recovery.c (do_one_pass), journal.c (e2fsck_get_journal): Add
269 missing brelse() calls to avoid memory leaks in error
270 paths. (Thanks to Michael C. Thompson for pointing these
271 out; they were originally found using Coverity.)
273 2006-05-13 Theodore Tso <tytso@mit.edu>
275 * badblocks.c (read_bad_blocks_file): Pass the private option -X
276 to badblocks so that e2fsck -cc will work correctly.
278 2006-05-08 Theodore Tso <tytso@mit.edu>
280 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Add support
281 for the lazy_bg feature; if the block group does not have
282 an initialized block or inode bitmaps/table, emulate what
283 the allocation bitmap would look like if no blocks or
284 inodes have been allocated.
286 2006-03-27 Theodore Ts'o <tytso@mit.edu>
288 * e2fsck.8.in: Add badblocks(8) to the See Also section.
289 (Addresses Debian Bug: #347295)
291 * Makefile.in, e2fsck.conf.5.in: Add man page documenting the
292 configuration file /etc/e2fsck.conf.
294 2006-03-22 Theodore Ts'o <tytso@mit.edu>
296 * profile.c (profile_update_file, profile_parse_file, parse_line,
297 parse_std_line): Integrate profile_std_line() into
298 parse_line(), and profile_parse_file() into
299 profile_update_file() to make the code tighter.
301 2006-03-18 Theodore Ts'o <tytso@mit.edu>
303 * unix.c (show_stats): Use blk_t instead of int when referring to
306 * emptydir.c, message.c, pass1b.c, pass2.c, recovery.c, unix.c:
307 Change printf statements to use %u instead of %d when
308 printing block numbers.
310 * unix.c (main): If the filesystem is not mounted, open the
311 filesystem in exclusive mode (to prevent 2.6 kernels from
312 mounting the filesystem while it is being checked).
314 2006-03-10 Theodore Ts'o <tytso@mit.edu>
316 * e2fsck.h, journal.c (e2fsck_fix_ext3_journal_hint),
317 problem.c (PR_0_EXTERNAL_JOURNAL_HINT),
318 problem.h (PR_0_EXTERNAL_JOURNAL_HINT), super.c: Check
319 to see if the superblock hint for the external journal
320 needs to be updated, and if so, offer to update it.
321 (Addresses Debian Bug: #355644)
323 2006-01-29 Theodore Ts'o <tytso@mit.edu>
325 * unix.c (check_if_skip): When skipping a check due to being on
326 battery, print an explanatory message to this effect. Add
327 an e2fsck configuration option defer_check_on_battery
328 which defaults to true. If the configuration option is
329 turned off, then e2fsck will not attempt to defer
330 filesystem checks when the system is running on battery.
331 (Addresses Debain Bug: #350306)
333 2006-01-06 Theodore Ts'o <tytso@mit.edu>
335 * profile.c (parse_std_line, dump_profile): Add support for
336 quoted strings in tag and section names. Changed
337 top-level section name parsing to ignore leading and
340 2006-01-05 Theodore Ts'o <tytso@mit.edu>
342 * profile.c (profile_init): If a directory is passed to
343 profile_init, then read all files which match [0-9a-zA-Z]*
344 in sort order. This allows handling of /etc/foo/conf.d
347 2006-01-04 Theodore Ts'o <tytso@mit.edu>
349 * profile.c: Eliminate the prf_data_t data structure and fold it
350 back into prof_file_t. Eschew needless complexity!
352 * profile.c: Change syntax accepted by the profile parser. The
353 value of profile relations must not contain spaces unless
354 it is quoted; otherwise the parser will throw an error.
355 Comments are allowed anywhere and can be started with
356 either a ';' or a '#' character. The only place where
357 comments will not be intepreted as beginning a comment is
360 * profile.c (profile_parse_file, profile_set_syntax_err_cb): Add
361 support for a syntax error callback to allow better error
362 reporting to the user.
364 * e2fsck(PRS): Set a profile syntax error callback so we can
365 report errors in /etc/e2fsck.conf.
367 2006-01-02 Theodore Ts'o <tytso@mit.edu>
369 * profile.c, profile_helpers.c, profile_helpers.h: Boil down and
370 simplify profile.c, and move extra functionality that's
371 not needed into profile_helpers.c
373 2006-01-01 Theodore Ts'o <tytso@mit.edu>
375 * profile.c: Fix #include of com_err.h so that it isn't required
376 that the com_err development environment be installed.
377 (Addresses Debian Bug: #345519)
379 2005-12-31 Theodore Ts'o <tytso@mit.edu>
381 * problem.c (fix_problem), problemP.h: Add the ability for the
382 e2fsck configuration file to override the behaviour of
383 e2fsck when a particular filesystem problem is
384 encountered. This allows reconnecting an inode to
385 lost+found to not stop the boot sequence, if a system
386 administrator really badly wants this behaviour for some
387 specialized reason, for example.
389 * unix.c (main): If the e2fsck configuration file sets the
390 allow_cancellation option to be true, then if the
391 filesystem does not have any known problems, and was known
392 to be cleanly unmounted, then let e2fsck exit with a
393 status code of 0 instead of 32 (FSCK_CANCELED) so that the
394 bootup scripts will continue without stopping the boot.
395 (Addresses Debian Bug: #150295)
397 2005-12-30 Theodore Ts'o <tytso@mit.edu>
399 * e2fsck.c (e2fsck_free_context), unix.c (PRS), e2fsck.h: Use
400 the profile library to read in the /etc/e2fsck.conf file
403 * profile.c, profile.h, prof_err.et: Add the profile library code
404 to e2fsck. The profile library was originally written by
405 Theodore Ts'o in 1995 for use in the MIT Kerberos v5
406 library. It has been modified/enhanced/bug-fixed over
407 time by other members of the MIT Kerberos team. This
408 version was originally taken from the Kerberos v5
409 distribution, version 1.4.2, and radically simplified for
410 use in e2fsprogs. (Support for locking for multi-threaded
411 operations, being able to modify and update the
412 configuration file programmatically, and Mac/Windows
413 portability have been removed. It has been folded into a
414 single C source file to make it easier to fold into an
415 application program.)
417 * argv_parse.c, argv_parse.h: Added auxiliary programs used only
418 for building the profile test program.
420 2005-12-18 Theodore Ts'o <tytso@mit.edu>
422 * problem.c (PR_0_FUTURE_SB_LAST_MOUNT,
423 PR_0_FUTURE_SB_LAST_WRITE): Make these problems things
424 which can be fixd by preen, since Debian's boot sequence
425 bogusly doesn't set the time correctly until potentially
426 very late in the bootup process, and this can cause false
427 positives that will cause users' systems to fail to
428 booting. (Addresses Debian Bugs #343662 and #343645)
430 2005-12-09 Theodore Ts'o <tytso@mit.edu>
432 * e2fsck.8.in: Clarify that e2fsck -c does a read-only scan of the
435 * unix.c (PRS): Fix typo in error message; thanks to Solar
436 Designer for pointing out the missing preposition.
437 (check_mount): Don't let the user run e2fsck -ccn on the
438 root partition, without warning that he or she might
439 be doing something Really Stupid.
441 * e2fsck.8.in: Clarify description of differences between the -p,
444 2005-09-24 Theodore Ts'o <tytso@mit.edu>
446 * super.c (check_super_block), problem.c, problem.h: Detect if the
447 superblock's last mount field or last write field is in
448 the future, and offer to fix if so. (Addresses Debian Bug
451 2005-07-25 Theodore Ts'o <tytso@mit.edu>
453 * unix.c (main): Fix a use-after-free bug of the e2fsck context
454 structure at the very end of the e2fsck run.
456 * pass1.c (pass1_write_inode): Fix false positive from valgrind;
457 don't do a needless structure copy via an assignment when
460 2005-07-04 Theodore Ts'o <tytso@mit.edu>
462 * problem.c: Remove period from the Pass 1C header, to be
463 consistent with the other Pass headers.
465 * pass2.c (e2fsck_process_bad_inode): Fixed bug which could cause
466 e2fsck to core dump if a disconnected inode contained an
467 extended attribute. This was actually caused by two bugs.
468 The first bug is that if the inode has been fully fixed
469 up, the code will attempt to remove the inode from the
470 inode_bad_map without checking to see if this bitmap is
471 present. Since it is cleared at the end of pass 2, if
472 e2fsck_process_bad_inode is called in pass 4 (as it is for
473 disconnected inodes), this would result in a core dump.
474 This bug was mostly hidden by a second bug, which caused
475 e2fsck_process_bad_inode() to consider all inodes without
476 an extended attribute to be not fixed. (Addresses Debian

486 by e2fsck for grammar and consistency.
488 2005-06-19 Theodore Ts'o <tytso@mit.edu>
490 * e2fsck.8.in: Make it clear that the -c, -l, and -L options are
491 never safe to use on a mounted filesystem, and in general,
492 running e2fsck on mounted filesystems is a bad idea.
494 2005-06-16 Theodore Ts'o <tytso@mit.edu>
496 * message.c: Add @m (multiply-claimed) and @n (invalid)
499 * problem.c: Clean up the problem messages displayed by e2fsck,
500 mostly based on suggestions from Benno Schulenberg.
502 2005-06-05 Theodore Ts'o <tytso@mit.edu>
504 * e2fsck.8.in: Add a request to the REPORTING BUGS section of the
505 man page to make sure that e2fsck's messages are printed
506 in English, and to send a raw e2image filesystem dump if

518 Debian Bugs: #304593)
520 2005-04-14 Theodore Ts'o <tytso@mit.edu>
522 * pass1b.c (pass1d): Don't offer to clone or delete the resize
523 inode; it's not allowed!
525 * e2fsck.c, e2fsck.h, journal.c, pass1.c, pass1b.c, pass2.c,
526 pass3.c, pass4.c, super.c, unix.c: Use a centrally stored
527 current time for "now" which can be overridden using the
528 E2FSCK_TIME environment variable, for better
529 reproducibility for regression tests.
531 2005-04-06 Theodore Ts'o <tytso@mit.edu>
533 * pass1.c (e2fsck_pass1): If the superblock last mount time (not
534 just the last write time) looks insane, then assume that
535 we can't do the LOW_DTIME checks.
537 2005-03-21 Theodore Ts'o <tytso@mit.edu>
539 * Release of E2fsprogs 1.37
541 2005-03-21 Theodore Ts'o <tytso@mit.edu>
543 * message.c, pass1.c, problem.c, problem.h, util.c: Integrate code
544 from Alex Thomas at Clusterfs to check extended attributes
547 * message.c (expand_inode_expression): Add support for %IS in
548 problem descriptions. Note that this only works if the
549 problem context has a pointer to a large inode!
551 * problem.h, problem.c (PR_1_EXTRA_ISIZE, PR_1_ATTR_NAME_LEN,
552 PR_1_ATTR_VALUE_OFFSET, PR_1_ATTR_VALUE_BLOCK,
553 PR_1_ATTR_VALUE_SIZE, PR_1_ATTR_HASH): Add new problem
556 * util.c (e2fsck_write_inode_full): New function.
558 * pass1.c (check_ea_in_inode, check_inode_extra_space): New
559 function which tests the validity of extended attributes
560 stored in a large inode.
561 (e2fsck_pass1): Call ext2fs_get_next_inode_full() instead
562 of get_next_inode(), and use an allocated inode which is
563 big enough to store extra portion of large inodes.
565 2005-03-20 Theodore Ts'o <tytso@mit.edu>
567 * super.c (check_super_block): Add sanity checks for the
568 superblock's inode_size field.
570 * pass3.c (check_root, e2fsck_get_lost_and_found): Call
571 ext2fs_write_new_inode() instead of ext2fs_write_inode().
573 * pass1.c (check_blocks): Move counting the extended attribute
574 block earlier so that we don't have to worry about
575 num_blocks wrapping for files which are too big.
577 2006-02-05 Theodore Ts'o <tytso@mit.edu>
579 * Release of E2fsprogs 1.36
581 2005-02-04 Theodore Ts'o <tytso@mit.edu>
583 * pass2.c (e2fsck_pass2), problem.c (PR_2_HTREE_FCLR), problem.h
584 (PR_2_HTREE_FCLR): Remove support for
585 --enable-clear-htree; this was only needed during the
586 early development of the htree patch.
588 2005-01-28 Theodore Ts'o <tytso@mit.edu>
590 * pass2.c (e2fsck_process_bad_inode): Fix a corner case involving
591 big-endian systems, long symlinks and i_file_acl set when
592 it shouldn't be. Without this bugfix, f_clear_xattr will
593 fail on big-endian machines.
595 * super.c (check_resize_inode): Deal with the case where the
596 resize inode can't be read; don't try to recreate the
597 resize inode unless the resize feature is actually
600 2005-01-27 Theodore Ts'o <tytso@mit.edu>
602 * super.c (check_resize_inode): If the resize inode has a zero
603 i_links_count or isn't a regular file, consider the resize
604 inode as invalid, and offer to recreate it.
606 * pass2.c (e2fsck_process_bad_inode): Offer to clear i_file_acl
607 before checking to see if an invalid inode should be
608 removed, since otherwise the fast symlink detection code
609 can get confused. Also clear the inode's entry in
610 inode_bad_map if the inode has been completely fixed.
611 (Addresses Red Hat Bugzilla #146284)
613 2005-01-25 Theodore Ts'o <tytso@mit.edu>
615 * unix.c (main, check_if_skip): Set the valid flag earlier, and if
616 it is cleared by the superblock tests, then assume that
617 the filesystem contains errors and must be checked.
619 * super.c (check_super_block): Check the individual block group
620 inode and block free counts, as well as the filesystem
621 inode and block free counts. If any of the block/inode
622 free counts is too large, force a full filesystem check.
623 (Addresses Debian Bug: #291571)
625 2005-01-19 Theodore Ts'o <tytso@mit.edu>
627 * unix.c (e2fsck_simple_progress): Use fixed integer math
628 to check to see if we're at 0 or 100%
629 (is_on_batt): Clean up gcc -Wall warning
630 (main): Remove dead code
632 2005-01-13 Matthias Andree <matthias.andree@gmx.de>
634 * unix.c: Do not call closedir if the handle is zero, to avoid
635 crashes when the /proc/acpi/ac_adapter directory is
636 missing, for instance on non-ACPI or non-Linux systems.
638 2005-01-09 Theodore Ts'o <tytso@mit.edu>
640 * pass1b.c: As part of converting configure.in from using the
641 "broken by design" 2.13 version of AC_CHECK_TYPE to
642 AC_CHECK_TYPES, if intptr_t isn't defined, manually
643 typedef it to long. (Addresses Debian Bug #289133)
645 2005-01-06 Theodore Ts'o <tytso@mit.edu>
647 * super.c (check_resize_inode): Use ext2fs_{read,write}_ind_block
648 so that byte swapping is handled on big-endian systems.
649 (check_super_block): Allow the number of reserved blocks
650 to be 50% of the number of blocks available, in order to
651 be consistent to what is allowed by tune2fs.
653 2004-12-24 Theodore Ts'o <tytso@mit.edu>
655 * pass1.c (e2fsck_pass1): At the end of the pass 1 processing, if
656 we have been signalled to do so, recreate the resize inode.
658 * super.c (check_resize_inode): New function which checks to make
659 sure the resize inode is valid. It is called by
660 check_super_block(). If it is invalid, it will signal to
661 pass1.c that the resize inode needs to recreate.
663 * e2fsck.h (E2F_FLAG_RESIZE_INODE): New flag
665 * problem.c, problem.h (PR_0_RESIZE_INODE_INVALID,
666 PR_1_RESIZE_INODE_CREATE): Add new problem codes.
668 2004-12-23 Theodore Ts'o <tytso@mit.edu>
670 * swapfs.c (swap_inodes): Since swap_inodes bypasses the inode
671 cache for speed reasons, we must flush it to avoid cache
674 2004-12-16 Theodore Ts'o <tytso@mit.edu>
676 * super.c (check_super_block): If the resize_inode feature is not
677 set, check to make sure that s_reserved_gdt_blocks is
678 zero, and that the resize inode is clear.
680 * problem.h (PR_0_NONZERO_RESERVED_GDT_BLOCKS,
681 PR_0_CLEAR_RESIZE_INODE): Add new problem codes.
683 2004-12-15 Theodore Ts'o <tytso@mit.edu>
685 * pass1.c (process_block): Applied resize inode patch. Mark the
686 DIND block of the resize inode as being in use.
688 2004-12-14 Theodore Ts'o <tytso@mit.edu>
690 * Makefile.in: Move strip command to install-strip target.
691 Use Linux-kernel-style makefile output for "make install"
693 * Makefile.in (installdirs): Use $(MKINSTALLDIRS) macro.
694 Remove sync in the "all" target.
696 2004-11-30 Theodore Ts'o <tytso@mit.edu>
698 * message.c (expand_inode_expression): If the TZ environment
699 variable is set to GMT, use gmtime() instead of
700 localtime() or ctime() to force the use of GMT. This is
701 because the dietlibc doesn't honor the TZ environment
704 * e2fsck.h: Add io_options to e2fsck_struct
706 * unix.c: If there is a question mark in the device name, separate
707 out the options to the IO layer, and pass it on to
710 * Makefile.in: Use Linux-kernel-style makefile output to make it
711 easier to see errors/warnings.
713 2004-10-04 Richard Mortimer <richm@oldelvet.org.uk>
715 * journal.c (e2fsck_check_ext3_journal): Attempt recovery of the
716 filesystem if the journal contains illegal block numbers.
718 2004-07-26 Theodore Ts'o <tytso@mit.edu>
720 * pass1.c (process_block): Change the limit of directory size from
723 2004-05-11 Theodore Ts'o <tytso@mit.edu>
725 * journal.c (sync_blockdev): Flush I/O caches to preserve ordering
726 constraints required by the journal recovery code. Thanks
727 to Junfeng Yang from the Stanford Metacompilation group
728 for pointing this out.
730 * jfs_user.h: Define sync_blockdev() as an emulated function,
731 instead just being a no-op.
733 2004-05-04 Theodore Ts'o <tytso@mit.edu>
735 * unix.c (check_if_skip): If the checkinterval is zero, then
736 disregard it when calculating when the next check will
739 2004-04-12 Theodore Ts'o <tytso@mit.edu>
741 * unix.c (is_on_batt): Be more flexible about the name of the ACPI
742 device that corresponds to the AC adapter. (Addresses
745 2004-04-03 Theodore Ts'o <tytso@mit.edu>
747 * Makefile.in: Update the modtime even if subst doesn't need to
748 update the e2fsck man page, to avoid always re-running
749 subst, especially since there are no dependencies on the
752 2004-02-28 Theodore Ts'o <tytso@mit.edu>
754 * Release of E2fsprogs 1.35
756 2004-02-24 Theodore Ts'o <tytso@mit.edu>
758 * unix.c (main, PRS), e2fsck.8.in: Add a new -k option which keeps
759 the existing badblocks list when using the -c option.
760 (Addresses Debian bug #229103)
762 2004-02-23 Theodore Ts'o <tytso@mit.edu>
764 * Makefile.in (PROFILED_LIBS, PROFILED_DEPLIBS): Fix reference to
765 libblkid so that the build will work with --enable-profile
766 (Addresses Sourceforge bug #811408)
768 2004-02-14 Theodore Ts'o <tytso@mit.edu>
770 * e2fsck.c (e2fsck_run): Clear the SETJMP_OK flag when returning
771 so we don't double longjump into an invalid stack frame.
772 (Thanks to Matthias Andree for providing this fix.)
774 2004-01-31 Theodore Ts'o <tytso@mit.edu>
776 * problem.c (fix_problem): Don't call print_e2fsck_message if the
777 message is empty; otherwise, the NLS substitution will
778 print the .po header, which is Just Wrong.
780 2004-01-30 Theodore Ts'o <tytso@mit.edu>
782 * pass2.c (deallocate_inode_block): Check to make sure the block
783 number is invalid before deallocating it, to avoid core
786 2003-12-12 Theodore Ts'o <tytso@mit.edu>
788 * pass3.c (check_directory): When reconnecting a directory, we may
789 need to create a lost+found directory. This may
790 invalidate our pointer to the directory information, so we
791 must look it up again after calling
792 e2fsck_reconnect_file(). (Addresses Debian bug #219640).
794 2003-12-10 Theodore Ts'o <tytso@mit.edu>
796 * e2fsck.h (E2F_FLAG_RESTARTED): Assign a unique flag bitfield to
797 E2F_FLAG_RESTARTED. This fixes a bug where if the user
798 specifies an alternate superblock, and the journal needs
799 to be replayed, e2fsck would erroneously assume that
800 journal had been run already without clearing the
801 NEEDS_RECOVERY flag, and bomb out with an error.
803 2003-12-07 Theodore Ts'o <tytso@mit.edu>
805 * badblocks.c, dict.c, ea_refcount.c, ehandler.c, journal.c,
806 pass1.c, pass1b.c, pass2.c, pass3.c, pass5.c, problem.c,
807 rehash.c, super.c, swapfs.c, unix.c, util.c, e2fsck.h: Fix
810 * recovery.c, jfs_user.h: Sync recovery.c with latest 2.5 kernel
813 2003-12-02 Theodore Ts'o <tytso@mit.edu>
815 * unix.c (main): When testing a disk using e2fsck -c, use the list
816 of new bad blocks to replace the current list of bad
817 blocks. This way "e2fsck -c" can be used to recover from
818 a corrupted bad block inode.
820 * badblocks.c (test_disk): Remove the test_disk() file; e2fsck
821 will just call read_bad_blocks_file() directly with the
822 file parameter set to NULL.
824 2003-09-14 Theodore Ts'o <tytso@mit.edu>
826 * unix.c (is_on_batt, check_if_skip): If running on battery, then
827 give an extra grace period before actually forcing a
828 check. That way the laptop will be biased to waiting
829 until we are on AC power before doing the filesystem
830 check. (Addresses Debian bug #205177)
832 2003-09-13 Theodore Ts'o <tytso@mit.edu>
834 * unix.c (check_if_skip): If the number of mounts until the next
835 forced filesystem check is 5 or less, mention this to the
836 user. (Addresses Debian bug #157194)
838 * pass1.c (e2fsck_pass1), problem.h (PR_1_BB_FS_BLOCK),
839 problem.c (PR_1_BB_FS_BLOCK, PR_1_BBINODE_BAD_METABLOCK_PROMPT):
840 Fix up the handling of corrupted indirect blocks in the
841 bad block. We now correctly handle the case where there
842 is an overlap between a block group descriptor or
843 a superblock and a bad block indirect block. In the case
844 where the indirect block is corrupted, we now suggest
847 2003-09-12 Theodore Ts'o <tytso@mit.edu>
849 * unix.c (PRS): Check the returned name from blkid_get_devname and
850 print an error if the requested LABEL/UUID does not exist.
852 2003-09-03 Theodore Ts'o <tytso@mit.edu>
854 * pass1.c (mark_table_blocks): Use the new function
855 ext2fs_reserve_super_and_bgd to calculate the blocks to be
858 2003-08-24 Theodore Ts'o <tytso@mit.edu>
860 * util.c (get_backup_sb): Check to make sure the context is passed
861 in non-NULL before trying to dereference it. Otherwise we
862 might core dump when called to expand %S in a problem
865 * e2fsck.8.in: Adjust description line so that apropos
866 "ext2" or "ext3" will find the man page. (Addresses
869 2003-08-21 Theodore Ts'o <tytso@mit.edu>
871 * journal.c (e2fsck_move_ext3_journal): When moving the journal or
872 backing up the journal inode, make sure it gets written to
875 2003-08-20 Theodore Ts'o <tytso@mit.edu>
877 * journal.c (e2fsck_move_ext3_journal): If the superblock's backup
878 journal information is not set, copy the journal inode
879 information to the superblock.
880 (e2fsck_get_journal): If the journal inode is corrupted,
881 synthesize one from the backup information in the
884 * problem.c, problem.h (PR_0_BACKUP_JNL): Add new problem code
885 which is used when we make a backup of the journal inode.
887 2003-08-19 Theodore Ts'o <tytso@mit.edu>
889 * e2fsck.h, unix.c (PRS, e2fsck_clear_progbar,
890 e2fsck_simple_progress): Don't print the ^A and ^B
891 characters which bracket the progress bar when the e2fsck
892 program is talking directly to a tty, but only when it is
893 being piped to another program. (Addresses Debian bug
895 * unix.c: Move some initialized variables to the BSS segment to
896 shrink the size of the e2fsck executable.
898 2003-08-01 Philipp Thomas <pthomas@suse.de>
900 * Include inttypes.h if present. New macros INT_TO_VOIDPTR and
901 VOIDPTR_TO_INT. Use them throughout for int<->void *
902 casts to fix 64-bit warnings.
904 * dirinfo.c, dx_dirinfo.c, e2fsck.c, ea_refcount.c, journal.c,
905 message.c, pass1.c, pass1b.c, pass2.c, pass3.c, pass4.c,
906 pass5.c, super.c, swapfs.c: ext2fs_getmem(),
907 ext2fs_free_mem(), and ext2fs_resize_mem() all now take a
908 'void *' instead of a 'void **' in order to avoid pointer
909 aliasing problems with GCC 3.x.
911 2003-07-25 Theodore Ts'o <tytso@mit.edu>
913 * Release of E2fsprogs 1.34
915 2003-07-06 Theodore Ts'o <tytso@mit.edu>
917 * pass2.c: Fix gcc -Wall nitpicks (missing #include <string.h>)
919 * dict.c, dict.h: Fix gcc -Wall nitpicks (indented cpp directives)
921 2003-06-8 Theodore Ts'o <tytso@mit.edu>
923 * problem.c: Fix spelling error.
925 2003-05-17 Theodore Ts'o <tytso@mit.edu>
927 * unix.c (show_stats), e2fsck.h: Use ngettext (abbreivated with
928 the macro P_(str1, str2, n)) to simplify the statistics
931 2003-05-05 Theodore Ts'o <tytso@mit.edu>
933 * unix.c (main): If --enable-testio-debug is set, then use the
934 test_io manager so we can watch what e2fsck is doing.
936 2003-05-03 Theodore Ts'o <tytso@mit.edu>
938 * unix.c (show_stats): Remove uneeded use of _() around string
941 * problem.c: Mark two strings (PR_1_RELOC_TO and
942 PR_2_NON_UNIQUE_FILE) as not being printf format strings.
943 Fix typo (doubled 'is') in PR_2_FILE_ACL_BAD.
945 * Makefile.in: Add $(LIBINTL) to the link line so we can support
946 using the internal gettext library.
948 * e2fsck.h: Add #ifndef protection around LOCALEDIR definition.
950 2003-04-27 Theodore Ts'o <tytso@mit.edu>
952 * message.c (expand_at_expression): Fixed NLS support for message
955 2003-04-21 Theodore Ts'o <tytso@mit.edu>
957 * Release of E2fsprogs 1.33
959 2003-04-19 Theodore Ts'o <tytso@mit.edu>
961 * rehash.c: Fix lint warnings by including string.h and ctype.h
963 * pass2.c (dict_de_cmp): Fix lint warnings by using const pointers.
965 * unix.c (e2fsck_simple_progress), e2fsck.h: Fix lint warnings by
966 using const pointers. Remove unused variables.
968 2003-04-17 Theodore Ts'o <tytso@mit.edu>
970 * rehash.c (name_cmp): Sort the deleted inodes to the end of the
971 list, for portability to systems that whose qsort does not
972 perform a stable sort.
974 2003-04-16 Theodore Ts'o <tytso@mit.edu>
976 * unix.c: Bracket progress bar output with control-A and control-B
977 characters. These characters are used as in-band
978 signalling to allow a logging program to filter out the
980 (PRS): Use setvbuf instead of setbuf to force stdout and
981 stderr to be non-buffered when the stdout/stderr are a pipe.
982 This fixes a cosmetic problem when using e2fsck under
985 2003-04-12 Theodore Ts'o <tytso@mit.edu>
987 * unix.c: Add #ifdef around #include <sys/ioctl.h>
989 2003-04-05 Theodore Ts'o <tytso@mit.edu>
991 * super.c (check_super_block): Update the global free block and
992 inode counters from the block group specific counters
993 quietly. This is needed for an experimental patch which
994 eliminates locking the entire filesystem when allocating
995 blocks or inodes; if the filesystem is not unmounted
996 cleanly, the global counts may not be accurate.
998 2003-03-17 Theodore Ts'o <tytso@mit.edu>
1000 * util.c: Explicitly declare e2fsck_global_ctx as extern for the
1001 benefit of the Apple Darwin port.
1003 2003-03-15 Theodore Ts'o <tytso@mit.edu>
1005 * rehash.c (e2fsck_rehash_dir): If user specified the -n option,
1006 skip trying to write out directory.
1007 (e2fsck_rehash_directories): Fix the percentage
1008 calculation in the progress bar.
1010 2003-03-14 Theodore Ts'o <tytso@mit.edu>
1012 * problem.c, problem.h (PR_2_REPORT_DUP_DIRENT): Add new problem
1015 * pass2.c (check_dir_block): Check for duplicate filenames within
1016 a single directory block (because this is the easy case;
1017 we don't currently check for duplicates that span
1018 directory blocks, for now. Eventually for htree
1019 directories we can do this by searching for all directory
1020 blocks that have a hash overflow, and then searching the
1021 adjacent blocks to find all other potential duplicates.)
1023 * iscan.c, scantest.c, unix.c: And #ifdef protection around
1024 #include of malloc.h
1026 * rehash.c (duplicate_search_and_fix): Now search for duplicates
1027 filenames, and either prompt to remove a complete
1028 duplicate entry, or to rename a duplicate filename.
1029 (e2fsck_rehash_dir): Use a progress bar to report
1030 progress, and don't print all of the directory inodes as
1033 * problem.c, problem.h (PR_2_DUPLICATE_DIRENT,
1034 PR_2_NON_UNIQUE_FILE): New problem codes.
1036 * unix.c (e2fsck_simple_progress), e2fsck.h: New function which
1037 can be called to provide specialized progress bars that
1038 are not related to the top-level pass-based completion
1041 * pass3.c (e2fsck_adjust_inode_count), e2fsck.h: Export previously
1044 2003-03-06 <tytso@mit.edu>
1046 * e2fsck.8.in: Fix minor nit in the -C option. (Addresses Debian
1049 2003-03-01 Theodore Ts'o <tytso@mit.edu>
1051 * Makefile.in, journal.c, unix.c: Use blkid functions to find the
1052 journal from the UUID, and to interpret the device
1055 * e2fsck.c: Free the blkid_cache when releasing the e2fsck context
1058 * e2fsck.h: If strnlen is not present, define it as a macro which
1059 calls e2fsck_strlen(). Add prototype for string_copy().
1060 Add blkid_cache to e2fsck context, and make
1061 filesystem_name, device_name, and journal_name be
1062 non-const variables.
1064 * pass1.c, pass2.c: Remove static strnlen function
1066 * util.c (string_copy, e2fsck_strnlen): New functions
1068 2003-01-29 Theodore Ts'o <tytso@mit.edu>
1070 * unix.c (usage): Make descripton -c be a bit more explicit
1072 2003-01-22 Theodore Ts'o <tytso@mit.edu>
1074 * pass1.c (check_blocks): Use the EXT2_I_SIZE macro.
1076 2003-01-02 Theodore Ts'o <tytso@mit.edu>
1078 * unix.c (main): Detect if there is an attempt to run the journal
1079 twice, and abort with an error if this is the case.
1080 (Address IBM Bugzilla bug #1226)
1082 2002-12-18 Theodore Ts'o <tytso@mit.edu>
1084 * pass2.c (strnlen): Provide strnlen if libc doesn't.
1086 2003-11-19 Theodore Ts'o <tytso@mit.edu>
1088 * unix.c (PRS): Print an error if more than one of the -p/-a, -n
1089 or -y options are specified.
1091 2002-11-12 Theodore Ts'o <tytso@mit.edu>
1093 * problem.c: Make HTREE problems PR_PREEN_OK, so that we don't
1094 abort an e2fsck after the filesystem has been mounted
1095 using the 2.4 ext2 codebase.
1097 2002-11-09 Theodore Ts'o <tytso@mit.edu>
1099 * Release of E2fsprogs 1.32
1101 2002-11-08 Theodore Ts'o <tytso@mit.edu>
1103 * Release of E2fsprogs 1.31
1105 2002-11-08 <tytso@snap.thunk.org>
1107 * unix.c (main): Fix a bug where e2fsck could erroneously mark a
1108 filesystem as being valid if it was being checked and it
1109 is interrupted with a ^C. (Bug introduced in e2fsprogs
1112 * unix.c (PRS), journal.c: Set the default level of journal
1113 debugging to be 0, and allow the user to set the level of
1114 journal debugging by using the E2FSCK_JBD_DEBUG
1115 environment variable.
1117 * pass1.c (new_table_block), super.c (check_super_block), swapfs.c
1118 (swap_filesys): Clear EXT2_FLAG_MASTER_SB_ONLY to make
1119 sure the backup superblocks and group descriptors are
1120 updated when we make an important change to the
1121 superblocks and/or group descriptors. (i.e., generating a
1122 UUID, allocating filesystem metadata, or byte-swapping the
1125 2002-11-07 Theodore Ts'o <tytso@mit.edu>
1127 * e2fsck.h, unix.c (main, check_mount): Fix e2fsck so that it
1128 returns the appropriate exit code, so that the boot
1129 scripts will be told that they need to automatically
1132 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1134 * Release of E2fsprogs 1.30
1136 2002-10-31 Theodore Ts'o <tytso@mit.edu>
1138 * unix.c (usage), e2fsck.8.in: Add the -D option to the usage and
1139 command synopsis. (Addresses Debian bug #167108)
1141 * pass1.c (e2fsck_pass1): Check the superblock write time to see
1142 whether or not we can safely do the LOW_DTIME checks.
1143 (Addresses Sourceforge bug #620980)
1145 2002-10-30 Theodore Ts'o <tytso@mit.edu>
1147 * Makefile.in (install): Search all compression extensions when
1148 deleting old man pages.
1150 * pass1.c (mark_table_blocks): Fix bug in meta_bg support; only
1151 mark blocks legacy group descriptor blocks up to
1154 2002-10-20 Theodore Ts'o <tytso@valinux.com>
1156 * pass1.c (mark_table_blocks): Add support for the meta_blockgroup
1159 2002-10-13 Theodore Ts'o <tytso@mit.edu>
1161 * pass3.c (e2fsck_get_lost_and_found): Pass in mode 700 to
1164 * unix.c (show_stats): Fix format bug if NLS is in use.
1166 * journal.c, pass1.c, revoke.c, util.c: Fix gcc -Wall nits.
1168 2002-10-08 Theodore Ts'o <tytso@mit.edu>
1170 * pass3.c (e2fsck_get_lost_and_found): Create the lost+found
1171 directory with mode 0700.
1173 2002-10-02 Theodore Y. Ts'o <tytso@mit.edu>
1175 * pass2.c (parse_int_node, check_dir_block): Add byte-swap
1176 functions around the htree code, so that it works on
1177 big-endian machines.
1179 * swapfs.c (swap_filesys): For PPC machines, byte-swap the bitmap,
1180 since PPC big-endian filesystems were historically wierd.
1181 This is just for the regression test, since no one
1182 actually uses them anymore...
1184 2002-09-30 Theodore Ts'o <tytso@mit.edu>
1186 * problem.c, problem.h (PR_2_HTREE_BAD_LIMIT,
1187 PR_2_HTREE_BAD_COUNT, PR_2_HTREE_HASH_ORDER,
1188 PR_2_HTREE_BAD_DEPTH): Add new problem codes.
1190 * pass2.c (salvage_directory, check_dir_block): Avoid counting
1191 directory entries twice during a directory salvage. Make
1192 the salvaging algorithm smarter about directory entry size
1194 (parse_int_node): Add check to make sure the limit and
1195 count fields in the node headers are sane. Also check
1196 to make sure the hash table in ascending order.
1197 (pass2, htree_depth): For all leaf nodes, determine their
1198 depth in the tree, and make sure it matches with the depth
1199 in the htree root information.
1201 2002-09-29 Theodore Ts'o <tytso@mit.edu>
1203 * pass2.c (check_dir_block): Do a more paranoid check when trying
1204 to determine whether or not a directory entry is a
1205 completely empty leaf block or leaf node. Otherwise
1206 e2fsck might get confused into thinking that a valid dxdir
1209 * rehash.c (e2fsck_rehash_dir): Apply patch from Christopher Li
1210 which avoids creating an empty directory entry at the end
1211 of the directory block. This screws up earlier versions
1212 of the indexed directory patch.
1214 2002-09-28 Theodore Ts'o <tytso@mit.edu>
1216 * rehash.c (write_directory): Clear the index flag if by
1217 reoptimizing the directory, we bring it back into a
1219 (e2fsck_rehash_dir): Allow directories that contain two
1220 blocks to be indexed. Otherwise when they grow, they
1221 never will be indexed by the kernel.
1223 * unix.c (main): Only update the master superblock; there's no
1224 point updating the backup superblocks, and it speeds up
1227 * pass2.c (salvage_directory): New function called by
1228 check_dir_block() which is much more sophisticated about
1229 how it salvages corrupted filesystems.
1231 2001-09-24 Theodore Tso <tytso@mit.edu>
1233 * Release of E2fsprogs 1.29
1235 2002-09-06 Theodore Ts'o <tytso@mit.edu>
1237 * rehash.c (copy_dir_entries): Fix bug which caused corrupted
1238 directories if there are 4 or 8 bytes left over in a
1239 directory page when optimizing/reindexing a directory.
1241 2001-08-31 Theodore Tso <tytso@thunk.org>
1243 * Release of E2fsprogs 1.28
1245 2002-08-31 Theodore Ts'o <tytso@mit.edu>
1247 * ehandler.c (e2fsck_handle_read_error): If the user asks to
1248 ignore the error, offer to try forcing a write of the
1249 block to the disk; sometimes this will cause the drive to
1250 remap the bad block.
1252 2002-08-31 Theodore Ts'o <tytso@valinux.com>
1254 * pass2.c (e2fsck_pass2): If this is a HTREE directory, sort the
1255 dblist so that the first block of all of the directories
1256 is handled first so we can read the hash version
1258 (check_dir_block): Examine the root node for correctness,
1259 and offer to clear it if it is not correct. Also copy the
1260 hash version to the dx_dir structure, so that the proper
1261 hash function can be used for other blocks in the
1264 * problem.c, problem.h (PR_2_HTREE_BAD_ROOT): Add new problem code.
1266 2002-08-21 Theodore Ts'o <tytso@mit.edu>
1268 * problem.c: Fix PR_1_RELOC_BLOCK_ALLOCATE message to explain that
1269 it is necessary to find contiguous blocks in a particular
1272 2002-08-17 Theodore Ts'o <tytso@mit.edu>
1274 * e2fsck.8.in: Add clarifying text describing how e2fsck works
1275 with ext3 filesytems. (Addresses Debian bug #145044).
1277 * pass1.c (handle_htree): Add support for EXT2_HASH_TEA
1279 * e2fsck.h, e2fsck.c (e2fsck_allocate_context): Add new field to
1280 the e2fsck context, ext_attr_ver, which specifies the EA
1283 * unix.c (usage, parse_extended_opts, PRS), e2fsck.8.in: Add new
1284 option -E, which allows the users to specify extended
1285 options. Added ea_ver extended option.
1287 * pass1.c (e2fsck_pass1_check_device_inode): Add ext2_filsys
1288 argument to this function, so we can account for the
1289 presence of extended attribute blocks attached to device
1291 (e2fsck_pass1_check_symlink, e2fsck_pass1): Take into
1292 account the fact that symlinks can also have extended
1294 (check_ext_attr): Don't be flexible about the EA format
1295 version. Check against the version number in
1297 (check_blocks): Check all inodes, so that we account for
1298 extended attribute blocks belonging to special files.
1299 Clean up i_size checks.
1301 * pass1b.c (pass1b): Check all inodes, so that we account for
1302 extended attribute blocks belonging to special files.
1303 (delete_file_block): Use ext2fs_alloc_block_stats() to
1304 update the filesystem statistics.
1305 (delete_file): Attempt to decrement the extended
1306 attribute refcount, and free the EA block if the count
1308 (clone_file): Fixed bugs in EA handling. Don't call
1309 block_iterate on inodes that don't have a valid i_block[]
1310 array. Reread the base inode since it may have been
1311 changed by ext2fs_block_iterate. When updating inodes as
1312 part of cloning an EA block, write out the correct inode
1315 * pass2.c (deallocate_inode_block, deallocate_inode): Use standard
1316 ext2fs_alloc_*_stats functions to update the filesystem
1318 (deallocate_inode): Attempt to decrement the extended
1319 attribute refcount, and free the EA block if the count
1321 (e2fsck_process_bad_inode): Add extra argument to calls
1322 to e2fsck_pass1_check_device_inode ().
1324 * pass3.c (e2fsck_get_lost_and_found): Use standard
1325 ext2fs_alloc_*_stats functions to update the filesystem.
1326 statistics when creating /lost+found.
1327 (adjust_inode_count): Remove debugging code that can never
1330 * pass4.c (disconnect_inode): Add explanation about why we only
1331 clear inodes that have no data blocks and no EA blocks.
1332 Use ext2fs_inode_alloc_stats2 function to update the
1333 filesystem statistics when clearing a zero-length inode.
1335 * problem.c, problem.h (PR_1B_ADJ_EA_REFCOUNT,
1336 PR_2_ADJ_EA_REFCOUNT): Add new problem codes.
1338 * super.c (release_inode_block), (release_orphan_inodes): Use the
1339 standard ext2fs_alloc_*_stats functions to update the
1340 filesystem statistics.
1341 (release_inode_blocks): Attempt to decrement the extended
1342 attribute refcount, and free the EA block if the count
1345 2002-08-01 Theodore Ts'o <tytso@mit.edu>
1347 * dict.c, dict.h: New file from kazlib 1.20 which implements a
1350 * pass1b.c: Massive changes to take advantage of dict.c. This
1351 removes several O(n**2) algorithms from the rare case
1352 where there are a large number of blocks claimed by
1355 2002-07-24 Theodore Ts'o <tytso@mit.edu>
1357 * e2fsck.8.in, e2fsck.h, pass3.c (e2fsck_pass3), unix.c, rehash.c:
1358 Add new option -D, which requests e2fsck to optimize all
1359 directories. Rehash.c will also compress and sort
1360 non-indexed directories.
1362 * problem.c, problem.h: Rename PR_3A_REHASH_* to PR_3A_OPTIMIZE_*
1364 * unix.c (PRS): Make sure the signal_cancel is registered without
1367 * rehash.c (e2fsck_rehash_dir, copy_dir_entries, calculate_tree):
1368 Restructured code in e2fsck_rehash_dir into two new
1369 subroutines to make the code more understandable/maintainable.
1370 (set_root_node): Fixed bug which caused the root node to
1371 be invalid on non-FILETYPE filesystems due to an
1372 unitialized variable.
1373 (calculate_tree): Fix bug where pointers which might get
1374 invalidated if realloc() moves outdir->buf around.
1375 (e2fsck_rehash_dir): Fix memory leak bug.
1377 * pass3.c (e2fsck_get_lost_and_found), e2fsck.h, e2fsck.c:
1378 Exported as a public interface a function for finding the
1379 lost and found directory. Cache the location of the lost
1380 and found directory in the e2fsck context structure.
1382 * util.c (ask_yn, read_a_char): Note when the user has typed ^C,
1383 and abort processing by longjmp'ing to ctx->abort_loc.
1385 2002-07-23 Theodore Ts'o <tytso@mit.edu>
1387 * pass1.c (e2fsck_pass1): If e2fsck is run with -n, don't create
1388 the dirs_to_hash list, since we don't want to reindex
1389 directories if the filesystem is opened read-only.
1391 2002-07-21 Theodore Ts'o <tytso@mit.edu>
1393 * e2fsck.8.in: Document new exit code FSCK_CANCELED
1395 * unix.c (PRS, signal_cancel): Capture SIGINT and SIGTERM signals
1396 and set a flag in the e2fsck context indicating that
1397 cancellation has been requested, so that e2fsck will exit
1398 only at safe points.
1399 (main): Change the exit handling so that if a cancellation
1400 is requested, return FSCK_CANCELED (a new exit code 32).
1401 e2fsck can now return more than one exit code as part of a
1402 bitmask (as had been documented in the man page).
1404 * pass2.c (e2fsck_pass2, check_dir_block), pass3.c (e2fsck_pass3),
1405 pass4.c (e2fsck_pass4): Check to see if a cancellation was
1406 requested, and abort processing if necessary.
1408 2002-07-19 Theodore Ts'o <tytso@mit.edu>
1410 * rehash.c, Makefile.in: New file which rewrites directories using
1413 * problem.c (fix_problem), problemP.h (PR_PREEN_NOHDR): Add option
1414 which suppresses the header printed when in preen mode.
1416 * pass3.c (e2fsck_pass3): If there are entries on the dirs_to_hash
1417 list, call e2fsck_rehash_directories to reindex those
1419 (e2fsck_expand_directory): Generalize the old
1420 expand_dirctory() function so it can expand a directory to
1421 a guaranteed minimum size.
1423 * e2fsck.h (struct e2fsck_struct): Add the dirs_to_hash list. Add
1424 new function prototypes for rehash.c and for
1425 e2fsck_expand_directory().
1427 * e2fsck.c (e2fsck_reset_context): Free the dirs_to_hash list.
1429 * pass1.c (e2fsck_pass1): Initialize the dirs_to_hash list if the
1430 htree feature is present in the filesystem.
1431 (check_blocks): If a non-htree directory has more than 2
1432 blocks, put it on the dirs_to_hash list.
1434 * pass2.c (clear_htree): Add corrupt htree directories to the
1437 * problem.h, problem.c (PR_3A_PASS_HEADER, PR_3A_REHASH_ITER,
1438 PR_3A_REHASH_DIR_ERR, PR_3A_REHASH_DIR_HEADER,
1439 PR_3A_REHASH_DIR, PR_3A_REHASH_DIR_END): Add new problem codes
1441 * pass2.c (parse_int_node), problem.c (PR_2_HTREE_BADBLK): Fix
1444 2002-07-15 Theodore Ts'o <tytso@mit.edu>
1446 * pass2.c (e2fsck_pass2): Use dx_dir->numblocks instead of
1447 dx_dir->ino to indicate that a bad inode was cleared.
1449 2002-06-26 Theodore Ts'o <tytso@mit.edu>
1451 * pass1.c (check_blocks): Move htree handling to handle_htree().
1452 Factor out calls to ext2fs_write_inode so that it happens
1453 if dirty_inode is non-zero.
1454 (handle_htree): Add checks for invalid htree root, invalid
1455 hash version, invalid hash version, and htree depth too deep.
1457 * problem.h, problem.c (PR_1_HTREE_NODIR, PR_1_HTREE_BADROOT,
1458 PR_1_HTREE_HASHV, PR_1_HTREE_INCOMPAT, PR_1_HTREE_DEPTH):
1459 Add new problem codes.
1461 * pass2.c (parse_int_node): Fix silly typo.
1462 (check_dir_block): Change to use new ext2fs_dirhash()
1464 (pass2): Fixed two minor bugs discovered by the test case:
1465 Don't stop checking dxdir's after clearing a bad inode.
1466 If there is a bad max hash, make sure the bad_dir flag
1467 is set to make sure we try to clear inode.
1469 2002-06-25 Theodore Ts'o <tytso@mit.edu>
1471 * e2fsck.c (e2fsck_reset_context): Free the dx_dirinfo structure.
1473 * message.c: Add new abbrevations @h and @p, "HTREE directory
1474 inode" and "problem in".
1476 * pass1.c (check_blocks): If the inode has the INDEX_FL flag,
1477 register the block into the indexed directory data
1478 structures. Or if the filesystem doesn't have the
1479 DIR_INDEX flag, offer to clear the INDEX_FL.
1481 * pass2.c (e2fsck_pass2, parse_int_node): Add support check htree
1482 directories (we don't check all possible corruptions yet).
1484 * problem.h, problem.h (PR_1_HTREE_SET, PR_2_HTREE_NOTREF,
1485 PR_2_HTREE_DUPREF, PR_2_HTREE_MIN_HASH, PR_2_HTREE_MAX_HASH,
1486 PR_2_HTREE_CLEAR, PR_2_HTREE_FCLR, PR_2_HTREE_BADBLK): Add
1489 * unix.c (main): If ENABLE_HTREE is not defined, complain if the
1490 filesystem has the dir_index feature.
1492 * Makefile.in, e2fsck.h, dx_dirinfo.c: New file (and group of
1493 functions) which keeps track of blocks in HTREE directory
1496 2002-05-22 Andreas Dilger <adilger@clusterfs.com>
1498 * super.c (check_superblock): Check that the number of inodes and
1499 blocks in a group is less than 2^16, so that the free inode
1500 and block counts for a group fit into the group descriptor
1501 table fields. Any more than that would need a COMPAT flag.
1503 2002-05-22 Theodore Ts'o <tytso@mit.edu>
1505 * pass1.c (check_ext_attr): Update to support the V2 Bestbits EA
1506 format. We automatically determine from the first EA
1507 block we visit whether we are using the V1 or V2 format.
1509 2002-05-21 Theodore Ts'o <tytso@mit.edu>
1511 * pass1.c (process_block): If an inode has too many blocks or
1512 is too big, then offer to truncate the inode.
1513 (check_blocks): Don't bother checking the size to see if
1514 it's too big, since that's just a symptom, not the disease
1515 (which we're now appropriately checking in process_block).
1517 * problem.c, problem.h: Add new problem codes PR_1_INODE_TOOBIG,
1518 PR_1_TOOBIG_DIR, PR_1_TOOBIG_REG, PR_1_TOOBIG_SYMLINK, and
1519 add the latch code PR_LATCH_TOOBIG.
1521 2002-05-20 Theodore Ts'o <tytso@mit.edu>
1523 * e2fsck.h, pass1.c (e2fsck_pass1_check_symlink), pass2.c
1524 (e2fsck_process_bad_inode): Add an extra
1525 argument so a scratch buffer can be passed into the
1528 * pass1.c (e2fsck_pass1_check_device_inode,
1529 e2fsck_pass1_check_symlink): If the EXT2_INDEX_FL flag is
1530 set, then the device/FIFO is invalid.
1531 (check_immutable): Don't check for EXT2_INDEX_FL; we take
1532 care of that elsewhere now.
1533 (e2fsck_pass1): Check to see if the symlink is valid
1534 before we offer to clear any immutable bits. This matches
1535 the order in which we check other special files.
1537 * pass2.c (e2fsck_pass2): Allocate a bigger scratch buffer so we
1538 can pass part of it to e2fsck_process_bad_inode.
1540 * pass4.c (e2fsck_pass4): If we need to call
1541 e2fsck_process_bad_inode(), allocate the necessary scratch
1544 * problem.h, problem.c: Change PR_2_SYMLINK_SIZE to be
1545 PR_2_INVALID_SYMLINK, and change the text
1546 accordingly. Revert the text change for PR_1_SET_IMMUTABLE
1547 since we no longer check for EXT2_INDEX_FL in
1550 2002-05-18 Andreas Dilger <adilger@clusterfs.com>
1552 * pass1.c (e2fsck_pass1_check_symlink): Remove checks of
1553 immutable/append-only checks, since this is handled by
1554 check_immutable. For non-fast symlinks, read in the
1555 data block and check the length to make sure it
1556 matches with the inode size.
1557 (check_immutable): Generalize to also check for the
1559 (check_blocks): For non-regular files, signal a bad inode
1560 size if i_size_high is non-zero.
1562 * pass2.c: Only count large files if they are regular files
1563 (not just if they aren't directories).
1565 * problem.c, problem.h: Change comment for PR_2_SYMLINK_SIZE
1566 to indicate that it can be triggered by any symlink,
1567 not fast symlink. Change text for PR_1_SET_IMMUTABLE
1568 to indicate that it the EXT2_INDEX_FL was set.
1570 2002-05-17 Theodore Ts'o <tytso@mit.edu>
1572 * pass1.c (e2fsck_pass1): When calculating max_sizes, omit capping
1573 this value by the calculated value of max_sect_sizes.
1574 The inode may be a sparse inode, and the limit of
1575 max_sect_sizes assumed a non-sparse inode and a limit
1576 based on a 32-bit i_blocks field measured in 512 sectors.
1578 * super.c (check_super_block): Fix check for s_log_block_size so
1579 that takes into account fact that there is an offset of
1580 EXT2_MIN_BLOCK_LOG_SIZE.
1582 * pass1.c: Allocate max_sizes array to be big enough to support
1583 the larger block sizes.
1585 2002-05-16 Andreas Dilger <adilger@clusterfs.com>
1587 * unix.c (main), util.c (get_backup_sb): Use EXT2_MAX_BLOCK_SIZE
1588 instead of using a hardcoded value of 4096.
1590 * super.c (check_super_block): Change checks for s_log_block_size
1591 s_log_frag_size so they support the larger block sizes.
1593 * pass1.c (e2fsck_pass1): Calculate max_sizes array for block
1594 sizes up to EXT2_MAX_BLOCK_SIZE (to support block sizes
1597 2002-03-08 Theodore Tso <tytso@mit.edu>
1599 * Release of E2fsprogs 1.27
1601 2002-03-07 Theodore Tso <tytso@mit.edu>
1603 * journal.c, pass5.c, revoke.c: Fix gcc -Wall complaints
1605 2002-03-07 Theodore Tso <tytso@mit.edu>
1607 * unix.c (main): Don't close the filesystem before calling
1608 fatal_error(); this just causes a needless warning about a
1609 bad I/O manager magic number.
1611 * journal.c (e2fsck_check_ext3_journal): Offer to clear the inode
1612 in case the journal is too small, or the inode number in
1613 the superblock doesn't appear to be random.
1615 2002-03-06 Theodore Tso <tytso@mit.edu>
1617 * problem.h, problem.c: PR_5_BLOCK_RANGE_UNUSED,
1618 PR_5_BLOCK_RANGE_USED, PR_5_INODE_RANGE_UNUSED,
1619 PR_5_INODE_RANGE_USED: Add new problem codes.
1621 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Collapse
1622 reporting of adjacent blocks and inodes into a range.
1624 2002-03-04 Philipp Thomas <pthomas@suse.de>
1626 * unix.c (main): Newer libintl needs LC_CTYPE to be set in
1627 addition to LC_MESSAGES.
1629 2002-02-24 Theodore Tso <tytso@mit.edu>
1631 * Makefile.in (install): Install hard links for man pages for
1632 fsck.ext2 and fsck.ext3. Remove any compressed man
1633 pages before installing the man pages.
1635 2002-02-22 Theodore Tso <tytso@mit.edu>
1637 * journal.c: Improve code maintainability and reduce code size by
1638 moving common code paths in e2fsck_journal_init_dev() and
1639 e2fsck_journal_init_inode() into e2fsck_get_journal().
1640 Also fixed a memory leak in recover_ext3_journal().
1642 * super.c (release_orphan_inodes): Fix memory leak.
1644 2002-02-03 Theodore Tso <tytso@thunk.org>
1646 * Release of E2fsprogs 1.26
1648 2001-12-24 Theodore Tso <tytso@mit.edu>
1650 * unix.c (PRS): Don't allow the -c and -l/-L options to be
1651 specified at the same time.
1653 * e2fsck.h (E2F_OPT_WRITECHECK), unix.c (PRS),
1654 badblocks.c (read_bad_blocks_file): If two -c options are
1655 specified, then perform a non-destructive read/write scan
1658 * e2fsck.8.in: Document the double -c option; also encourage users
1659 to use -c instead of the -l/-L options since it's too hard
1660 for users to get things like the blocksize parameter correct.
1662 2001-12-23 Theodore Tso <tytso@mit.edu>
1664 * util.c (get_backup_sb): This function now searches for the
1665 backup superblock by iterating over possible blocksizes
1666 instead of defaulting a guess of 8193 if the superblock
1669 * message.c (expand_percent_expression), unix.c (main): Pass in
1670 new parameters to get_backup_sb. Also, in unix.c, use the
1671 blocksize paramter in the e2fsck context structure instead
1672 of using a static variable, since get_backup_sb wants to
1673 be able to set the blocksize paramter.
1675 * e2fsck.h: Update function prototype for get_backup_sb; also add
1676 the blocksize parameter to the e2fsck context structure.
1678 * Makefile.in, jfs_user.h: Move linux/jbd.h to
1679 ext2fs/kernel-jbd.h, to avoid using the system header
1680 file version of hbd.h when using diet glibc (since it
1681 forcibly adds /usr/include to the beginning of the
1682 include search path.)
1684 2001-12-21 Theodore Tso <tytso@mit.edu>
1686 * problem.c (fix_problem): Use ctx->filesystem_name if the
1687 ctx->device_name is NULL.
1689 * journal.c (e2fsck_check_ext3_journal): Give the opportunity to
1690 run the journal even if recovery flag is cleared. If
1691 we're using a backup superblock, run the journal by
1694 * e2fsck.h (E2F_OPT_FORCE), unix.c (PRS, check_if_skip): Use a
1695 bitfield in the e2fsck context flags word to indicate
1696 whether or not a check should be forced. This allows the
1697 journal code to set the option if necessary to force a
1700 * problem.h, problem.c: Remove PR_0_JOURNAL_RESET_JOURNAL, and add
1701 PR_0_JOURNAL_RUN and PR_0_JOURNAL_RUN_DEFAULT. Update
1702 problem decription texts.
1704 2001-12-16 Theodore Tso <tytso@mit.edu>
1706 * e2fsck.h (ext2fs_get_refcount_size), unix.c (check_mount, PRS),
1707 pass1.c (adjust_extattr_refcount),
1708 ea_refcount.c (ea_refcount_create): Fix gcc -Wall nits.
1710 * recovery.c, revoke.c: Update to versions from 2.4.17-pre8.
1712 * journal.c, jfs_user.h: Update support code for new version of
1713 recover.c and revoke.c. Fix support for filesystems with
1716 2001-11-30 Gabriel Paubert <paubert@iram.es>
1718 * journal.c (e2fsck_journal_load): Fix an endianness bug.
1720 2001-11-26 Theodore Tso <tytso@mit.edu>
1722 * super.c (check_super_block): Make sure that if the inode table
1723 or allocation bitmap is zero, that it is marked as
1724 invalid, so that in pass #1, a new bitmap/inode table gets
1725 properly allocated. (Addresses Debian Bug #116975)
1727 2001-11-24 Theodore Tso <tytso@mit.edu>
1729 * e2fsck.8.in: Fix minor typo in man page and clarify device
1732 2001-10-07 Theodore Tso <tytso@mit.edu>
1734 * journal.c (clear_v2_journal_fields, e2fsck_journal_load): If the
1735 V2 fields are set on a V1 journal superblock, or an
1736 internal V2 journal has s_nr_users is non-zero, clear the
1737 entire journal superblock beyond the V1 superblock. This
1738 fixes botched V1->V2 updates.
1740 * problem.c, problem.h (PR_0_CLEAR_V2_JOURNAL): Add new problem code.
1742 2001-09-20 Theodore Tso <tytso@mit.edu>
1744 * e2fsck.h, journal.c (e2fsck_move_ext3_journal): Add new function
1745 which will automatically relocate the ext3 journal from a
1746 visible file to an invisible journal file if the
1747 filesystem has been opened read/write.
1749 * super.c (check_super_block): Add call to e2fsck_move_ext3_journal
1751 * problem.c, problem.h (PR_0_MOVE_JOURNAL, PR_0_ERR_MOVE_JOURNAL):
1752 Add new problem codes.
1754 2001-09-20 Theodore Tso <tytso@thunk.org>
1756 * Release of E2fsprogs 1.25
1758 2001-09-19 Theodore Tso <tytso@mit.edu>
1760 * unix.c (main): If a superblock is specified explicitly by the
1761 user, don't try to automatically fall back to an
1762 alternate superblock.
1764 2001-09-02 Theodore Tso <tytso@thunk.org>
1766 * Release of E2fsprogs 1.24a
1768 2001-08-30 Theodore Tso <tytso@thunk.org>
1770 * Release of E2fsprogs 1.24
1772 2001-08-30 Theodore Tso <tytso@valinux.com>
1774 * pass1.c (e2fsck_pass1): For EXT2_RESIZE_INO, allow its i_mode to
1775 either be zero or a regular file (for compatibility with
1776 Andreas's on-line resizing programs).
1778 2001-08-27 Theodore Tso <tytso@valinux.com>
1780 * unix.c (main): Remove EXT2FS_VERSION from the version display,
1781 since it only confuses people.
1783 * pass1.c (strnlen): Provide strnlen if libc doesn't.
1785 2001-08-15 Theodore Tso <tytso@valinux.com>
1787 * Release of E2fsprogs 1.23
1789 2001-08-13 Theodore Tso <tytso@valinux.com>
1791 * super.c (release_orphan_inodes): If the filesystem contains
1792 errors, don't run the orphan * list, since the orphan list
1795 * pass1.c (check_size): Fix logic in check_size; the previous code
1796 only offered to clear the inode size fields if both size
1797 and i_size_high were zero.
1798 (e2fsck_pass1_check_device_inode): If i_blocks is
1799 non-zero, then assume that the device/socket/fifo inode
1802 2001-08-09 Theodore Tso <tytso@valinux.com>
1804 * pass1.c, pass2.c, problem.c, problem.h: Fix bug introduced by
1805 Andreas's symlink code; check_blocks() was unconditionally
1806 testing inode_bad_map without checking to see if it
1807 existed first. Fixed problem a different way; we now no
1808 longer check inode_bad_map at all, since the file might
1809 not get deleted in pass 2 anyway. We move the large file
1810 feature reconciliation code to to e2fsck_pass2(), and in
1811 deallocate_inode() in pass2.c, we decrement the large
1812 files counter if we're about to delete a large file.
1814 * unix.c (show_stats): Print the number of large files in verbose
1817 2001-08-07 Theodore Tso <tytso@valinux.com>
1819 * journal.c (recover_ext3_journal): If s_errno is set in the
1820 journal superblock, set the EXT2_ERROR_FS flag in the
1821 filesystem superblock after the journal is run.
1823 2001-08-04 Andreas Dilger <root@lynx.adilger.int>
1825 * message.c: Change comments for %D and %d expansion in e2fsck
1826 problem codes. It was not consistent which was for dirent
1827 expansion, and which was for directory number expansion.
1829 * problem.c (PR_2_FINAL_RECLEN, PR_2_BAD_FILETYPE): Fix problem
1830 codes which got caught by the confusion between %D and %d.
1832 2001-08-04 Theodore Tso <tytso@valinux.com>
1834 * problem.c (PR_2_SYMLINK_SIZE): Change description to make it
1835 more clear (and remove %s expansion). Also add missing
1836 periods to the end of a number of problem descriptions.
1838 * pass2.c (e2fsck_process_bad_inode): Remove unneeded problem
1839 context string set now that the problem description for
1840 PR_2_SYMLINK_SIZE has been changed.
1842 * pass1.c (e2fsck_pass1_check_symlink): Consolidate some checks,
1843 and check the validity of the symlink block here (so that
1844 we detect this case here instead of later). Also use
1845 sizeof(inode->i_block) instead EXT2_LINK_DIR.
1847 2001-07-30 Theodore Tso <tytso@valinux.com>
1849 * unix.c (check_mount): Remove the code which tested for the root
1850 filesystem being mounted read-only, and depend on the
1851 results flags from ext2fs_check_if_mounted.
1853 2001-07-29 Theodore Tso <tytso@valinux.com>
1855 * unix.c (check_if_skip): Free the e2fsck context structure on a
1856 normal clean filesystem exit, to make it easier to find
1858 (PRS): Only update the path to include /sbin at the
1859 beginning if the -c option is given, again to make it
1860 easier to find memory leaks.
1861 (main): Move the final print_resource_track call after the
1862 filesystem and the context are freed.
1864 * journal.c (e2fsck_journal_init_dev): Avoid memory leak if we
1865 need to search for the journal device.
1866 (e2fsck_journal_release): Free the journal IO channel when
1867 we release the journal handle, to avoid a memory leak.
1869 * e2fsck.c (e2fsck_reset_context): Fix bug; only close the io
1870 channel if it is *different* from the filesystem io
1873 2001-07-27 Theodore Tso <tytso@valinux.com>
1875 * problem.c (PR_1_SET_IMMUTABLE): Clarify problem message.
1877 * pass1.c (e2fsck_pass1): Check for symlinks that have the
1878 immutable flag set (and offer to clear them).
1880 2001-07-26 Theodore Tso <tytso@valinux.com>
1882 * pass1.c (e2fsck_pass1): Free ctx->block_ea_map at the end of
1885 2001-07-25 Theodore Tso <tytso@valinux.com>
1887 * pass1.c (check_ext_attr): Skip zero-length EA entries.
1889 * problem.c: PR_1_EA_ALLOC_COLLISION shouldn't abort, but should
1890 prompt to clear the EA block.
1892 2001-07-22 Theodore Tso <tytso@valinux.com>
1894 * journal.c (ll_rw_block): Use ctx->journal_io instead of the
1895 filesystem's io_channel.
1896 (e2fsck_journal_init_dev): New function which supports
1897 initialization of the external journal.
1898 (e2fsck_get_journal): Remove code which flagged an error
1899 if the superblock reported the use of an external journal.
1900 (ext3_journal_via_mount): Remove unsued, #ifdefed out function.
1902 * problem.c, problem.h: Removed error codes no longer used
1903 (PR_0_JOURNAL_UNSUPP_DEV, PR_0_JOURNAL_BAD_DEV,
1904 PR_0_JOURNAL_UNSUPP_UUID) and replace them with new error
1905 codes related with failures in loading the external
1906 journal (PR_0_JOURNAL_UNSUPP_MULTIFS,
1907 PR_0_CANT_FIND_JOURNAL, PR_0_EXT_JOURNAL_BAD_SUPER).
1908 Also changed the text assocated with PR_0_JOURNAL_BAD_UUID
1909 to reflect the case where the external journal isn't
1910 correct for this filesystem.
1912 * unix.c (PRS), e2fsck.8.in: Add new option -j which allows
1913 the user to specify the pathname to find the external journal.
1915 * e2fsck.c (e2fsck_reset_context): Close journal_io if it isn't
1916 the same as the filesystem io_channel.
1918 * e2fsck.h: Add new fields (journal_io and journal_name) in the
1919 context structure to support external journals.
1921 2001-07-20 Theodore Tso <tytso@valinux.com>
1923 * unix.c (main): Add an explicit warning when the filesystem is
1924 left not completely fixed when e2fsck exits. (Addresses
1925 Debian bug #104502.)
1927 2001-07-19 Theodore Tso <tytso@valinux.com>
1929 * pass1.c (check_ext_attr): The entire EA block is now checked to
1930 make sure that parts of the EA block aren't being used for
1933 * Makefile.in e2fsck.h, region.c: New file which is used to detect
1934 collisions in extended attribute block.
1936 * problem.h, problem.c (PR_1_EA_MULTI_BLOCK, PR_1_EA_ALLOC_REGION,
1937 PR_1_EA_ALLOC_COLLISION, PR_1_EA_BAD_NAME,
1938 PR_1_EA_BAD_VALUE): Add new problem codes.
1940 2001-07-10 Theodore Tso <tytso@valinux.com>
1942 * journal.c (e2fsck_run_ext3_journal): Only call ext3_flush() if
1943 the superblock is dirty.
1945 2001-07-07 Theodore Tso <tytso@valinux.com>
1947 * pass1b.c (pass1b, process_pass1b_block): Change the num_bad
1948 field calculation so that it only counts EA block entries
1949 as a single multiply claimed block (since once we clone
1950 the EA blocks for one inode, we fix the problem for all of
1951 the other inodes). Also, I moved the num_bad calculation
1952 from process_pass1b_block to the end of pass1b. This
1953 fixes a *significant* performance bug in pass1b which hit
1954 people who had to had a lot of multiply claimed blocks.
1955 (Can you say O(n**3) boys and girls? I knew you could...
1956 Fortunately, this case didn't happen that much in actual
1959 * pass1.c (e2fsck_pass1): Defer inodes which have an extended
1960 attribute block for later processing to avoid extra seeks
1962 (process_inode_cmp): If there is no indirect block, sort
1963 by the extended attribute (i_file_acl) block.
1965 * pass1b.c (clone_file_block): Fix bugs when cloning extended
1966 attribute blocks. Moved free of block_buf to after the
1967 code which clones the extattr block, and fixed logic for
1968 changing pointers to the extended attribute field in the
1969 inodes which were affected.
1970 (decrement_badcount): New function which is used whenever
1971 we need to decrement the number of files which claim a
1972 particular bad block. Fixed bug where delete_file wasn't
1973 checking check_if_fs_block() before clearing the entry in
1974 block_dup_map. This could cause a block which was claimed
1975 by multiple files as well as the filesystem metadata to
1976 not be completely fixed.
1978 * pass1.c (adjust_extattr_refcount): Add new function which
1979 adjusts the reference counts of extended attribute blocks
1980 if needed, both up and down.
1981 (e2fsck_pass1): If the refcount or refcount_extra
1982 structure are present, call adjust_extattr_refcount(),
1983 and free it afterwards.
1985 * problem.h, problem.c (PR_1_EXTATTR_READ_ABORT,
1986 PR_1_EXTATTR_REFCOUNT, PR_1_EXTATTR_WRITE): Add new
1989 2001-07-02 Theodore Tso <tytso@valinux.com>
1991 * pass1.c (e2fsck_pass1, check_ext_attr, check_blocks): Add
1992 initial support for scanning extended attribute blocks.
1994 * e2fsck.c (e2fsck_reset_context): free extended attribute
1997 * e2fsck.h: Add new fields for accounting for the extended
2000 * Makefile.in, ea_refcount.c, e2fsck.h: Add new file which
2001 implements a reference count abstraction.
2003 * problem.c, problem.h: Add new problem codes PR_1_ALLOCATE_REFCOUNT,
2004 PR_1_READ_EA_BLOCK, PR_1_BAD_EA_BLOCK, PR_2_FILE_ACL_BAD
2006 * message.c: Add "@a" as an abbreviation for "extended attribute"
2008 * pass1b.c (clone_file): Add code which handles cloning an
2009 extended attribute block.
2011 * pass1b.c (delete_file):
2012 * pass2.c (deallocate_inode): If the inode contains an extended
2013 attribute block in the file_acl field, clear it and
2014 deallocate the block.
2016 2001-06-28 Theodore Tso <tytso@valinux.com>
2018 * pass2.c (e2fsck_process_bad_inode): Deal with inodes which are
2019 marked bad because of an invalid file_acl (either because
2020 EXT2_FEATURE_COMPAT_EXT_ATTR is not set, or because the
2021 block number in file_acl is bad.
2023 2001-06-29 Theodore Tso <tytso@valinux.com>
2025 * unix.c (show_stats): Use long long to calculate the percentage
2026 of the number of blocks in use in the filesystem.
2028 2001-06-23 Theodore Tso <tytso@valinux.com>
2030 * Release of E2fsprogs 1.22
2032 2001-06-22 Theodore Tso <tytso@valinux.com>
2034 * flushb.c: Use platform independent method of defining the
2035 BLKFLSBUF ioctl. Also include sys/mount.h since on newer
2036 platforms BLKFLSBUF is defined there.
2038 2001-06-19 Theodore Tso <tytso@valinux.com>
2040 * super.c (release_inode_blocks): Don't try to release the blocks
2041 if the orphaned inode is a device file, symlink, or some
2042 other kind of special file that doesn't have a block list.
2044 2001-06-15 Theodore Tso <tytso@valinux.com>
2046 * Release of E2fsprogs 1.21
2048 2001-06-13 Theodore Tso <tytso@valinux.com>
2050 * unix.c (check_if_skip): Adapted patch from Andreas Dilger which
2051 prints the number of mounts or days elapsed since the last
2052 check when e2fsck is forced to check an otherwise clean
2055 2001-06-12 Theodore Tso <tytso@valinux.com>
2057 * badblocks.c: Stop using the compatibility badblocks function,
2058 and use the ext2fs_badblocks_* functions instead.
2060 2001-06-11 Theodore Tso <tytso@valinux.com>
2062 * unix.c (PRS): Fix bug introduced in 1.20 which broke the -F
2065 * Makefile.in: Add message.c and swapfs.c to the list of source
2066 files to build the make depend.
2068 * swapfs.c, unix.c: Only support the -s and -S options to e2fsck
2069 if ENABLE_SWAPFS is defined.
2071 2001-06-08 Theodore Tso <tytso@valinux.com>
2073 * recover.c, revoke.c: Synchronize with ext3 0.7a
2075 2001-06-02 Theodore Tso <tytso@valinux.com>
2077 * recovery.c (scan_revoke_records): Fix bug in recovery code;
2078 missing byte order conversion.
2080 * pass1.c (mark_inode_bad): Replace alloc_bad_map with a function
2081 which sets the bit in the bad inode bitmap.
2082 (e2fsck_pass1): Check for fast symlinks with an invalid
2083 size, and set the bad inode map in that case.
2084 (check_size): Check i_size_high for special files and
2085 prompt to clear it along with i_size if non-zero.
2087 * pass2.c (e2fsck_process_bad_inode): Check for fast symlinks with
2088 an invalid size and prompt the user if the inode should be
2091 * problem.h, problem.c (PR_2_SYMLINK_SIZE): Added new problem code.
2093 2001-06-01 Theodore Tso <tytso@valinux.com>
2095 * problem.c, problem.h: Change PR_0_JOURNAL_UNSUPP_INCOMPAT and
2096 PR_0_JOURNAL_UNSUPP_ROCOMPAT so they aren't fatal errors,
2097 but prompt to see if the user should abort. Removed the
2098 PR_0_JOURNAL_RESET_COMPAT problem code.
2100 * journal.c (e2fsck_journal_load): If there are incompatible
2101 journal flags, just return an error code.
2102 (e2fsck_check_ext3_journal): If e2fsck_journal_load
2103 returns an error code indicating that there are
2104 incompatible journal flag, check to see if we should
2105 abort, and then offer to clear the journal.
2106 (Addresses Debian bug #98527.)
2108 * Makefile.in: Move include/asm/types.h.in to
2109 lib/ext2fs/ext2_types.h.in.
2111 2001-06-01 Theodore Tso <tytso@valinux.com>
2113 * pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
2114 pass1_check_directory): Add a safety check to make sure
2115 ctx->stashed_inode is non-zero.
2117 * pass1b.c (pass1b): Use e2fsck_use_inode_shortcuts() to disable
2118 the inode shortcut processing, instead of manually
2119 clearing only half of the function pointers that needed to
2120 be NULL'ed out. This caused nasty bugs if the last inode
2121 in the filesystem needed dup block processing.
2123 * pass1b.c (clone_file_block): When cloning a directory's metadata
2124 block, don't try to update the directory block list
2125 database, since indirect blocks aren't stored in the
2126 database and the resulting error will abort the file clone
2129 2001-05-25 Theodore Tso <tytso@valinux.com>
2131 * Release of E2fsprogs 1.20
2133 2001-05-25 Theodore Tso <tytso@valinux.com>
2135 * journal.c (e2fsck_journal_reset_super): Remove extraneous line
2137 2001-05-23 Theodore Tso <tytso@valinux.com>
2139 * journal.c (e2fsck_journal_reset_super): Fix bug; the reset
2140 journal wasn't getting written out to disk since the dirty
2141 bit wasn't being set on the buffer.
2142 (e2fsck_journal_load): Don't print an error message if the
2143 journal version number is wrong; just return a error code
2144 reflecting this fact. If the block type in the journal
2145 superblcok is obviously not a version number, report the
2146 journal is corrupted.
2147 (e2fsck_check_ext3_journal): On an unsupported journal
2148 version, prompt to abort by default, but then offer a
2149 chance to clear the journal as corrupt.
2151 * problem.c, problem.h (PR_0_JOURNAL_UNSUPP_VERSION): Added new
2154 2001-05-14 Theodore Tso <tytso@valinux.com>
2156 * pass1.c: Treat inodes with a low dtime (that were from a
2157 corrupted orphan list) specially.
2159 * problem.c, problem.h: Add new problem codes PR_1_LOW_DTIME and
2160 PR_1_ORPHAN_LIST_REFUGEES, and a new latch group,
2163 * problemP.h: Expand the size of the problem flag to be an int
2164 instead of a short. Expand space in the flag word which
2165 is reserved for problem latch flags from 3 bits to 8 bits.
2167 * e2fsck.h, scantest.c: Change location of ext2_fs.h to be
2170 * super.c (check_super_block): Be more strict on checking
2171 s_r_blocks_count superblock field.
2173 2001-05-13 Theodore Tso <tytso@valinux.com>
2175 * problem.c, problem.h (PR_0_JOURNAL_UNSUPP_ROCOMPAT,
2176 PR_0_JOURNAL_UNSUPP_INCOMPAT, PR_0_JOURNAL_RESET_COMPAT):
2179 * journal.c (e2fsck_journal_load): Use a problem code to
2180 report unsupported feature flags. There is code to
2181 clear unsupported flags, but since this is dangerous,
2182 it's not allowed in the problem code table.
2184 2001-05-11 Andreas Dilger <adilger@turbolinux.com>
2186 * journal.c (e2fsck_journal_reset_super): initialize the journal
2187 sequence number to a random value to avoid recovering
2188 bad transactions from a corrupt journal.
2190 2001-05-13 Theodore Tso <tytso@valinux.com>
2192 * journal.c: Code cleanup; initialize journal_enable_debug using
2195 2001-05-12 Theodore Tso <tytso@valinux.com>
2197 * unix.c (PRS): Skip validation of -C's file descriptor if it is
2198 zero, since that is special case.
2200 2001-05-09 Theodore Tso <tytso@valinux.com>
2202 * super.c (release_orphan_inodes): Add gettext quoting around
2203 "Truncating" and "Clearing" for i18n.
2205 2001-05-05 Theodore Tso <tytso@valinux.com>
2207 * util.c (fatal_error): Use the correct magic number when checking
2208 the magic number for the io_channel data structure. Also
2209 remove extraneous call to io_channel_flush() that was left
2210 over from an editing session.
2212 * pass2.c (check_dir_block): Ignore EXT2_ET_DIR_CORRUPTED errors
2213 from ext2fs_read_dir_block().
2215 2001-05-01 Theodore Tso <tytso@valinux.com>
2217 * unix.c (PRS): Validate the completion information file
2218 descriptor so that the completion bar won't get
2219 accidentally written onto the disk.
2221 * e2fsck.8.in: Add explanation that you can use mke2fs -n -b
2222 blocksize to printout alternate superblock locations.
2224 2001-04-26 Theodore Tso <tytso@valinux.com>
2226 * unix.c (check_if_skip): If the max_mount_count is zero, treat it
2227 as having no count set.
2229 2001-04-16 Theodore Tso <tytso@valinux.com>
2231 * super.c (check_super_block): Fix bad calculation of
2232 inodes_per_block, and tighten min/max checks to be a bit
2233 more paranoid. Thanks to Andreas Dilger for pointing out
2236 2001-03-29 Theodore Tso <tytso@valinux.com>
2238 * journal.c (mark_buffer_uptodate): Add emulation of kernel
2239 function mark_buffer_uptodate.
2241 * recovery.c, revoke.c: Synchronize with 0.6b ext3 files.
2243 2001-02-12 Theodore Tso <tytso@valinux.com>
2245 * journal.c (e2fsck_run_ext3_journal): Force a flush of the
2246 filesystem and io_channel before replaying the journal.
2248 2001-01-17 Theodore Ts'o <tytso@valinux.com>
2250 * pass1.c (check_blocks): Fix large file checking code so that
2251 files > 2GB are considered large files, and restrict
2252 directories from being > 2GB.
2254 2001-01-12 Theodore Ts'o <tytso@valinux.com>
2256 * journal.c (e2fsck_journal_fix_unsupported_super): Remove unused
2257 function. Add FIXME notes to e2fsck_get_journal(), from
2260 * pass1.c (e2fsck_pass1): Cap the maximum legal size of a file by
2261 the limit caused by the fact that i_blocks is in 512 byte
2262 units, and that the Linux buffer cache also fundamentally
2263 assumes 512 byte sectors.
2264 Make sure that the journal inode is a regular file, and
2265 when clearing an unused journal inode, make sure the
2266 icount db is updated.
2268 * problem.c, problem.h (PR_1_JOURNAL_BAD_MODE): Add new problem code.
2270 * problem.c: For PR_1_RESERVED_BAD_MODE, print a description of
2271 the reserved inode. In PR_0_JOURNAL_HAS_JOURNAL, prompt
2272 to clear the journal, rather than deleting it (which is
2273 more accurate). (From Andreas Dilger.)
2275 * journal.c: Make sure all functions which return an error code
2276 use the errcode_t return type, and not "int"
2277 (e2fsck_journal_release): Add new parameter, "drop",
2278 which is used when we just want to deallocate the journal
2279 without trying to write out any changes.
2280 (mark_buffer_clean): New function
2281 (e2fsck_check_ext3_journal): If we fail loading the
2282 journal, make sure we free all memory associated with it.
2283 (recover_ext3_journal): If we fail to load the journal or
2284 initialize the revoke data structures, make sure we free all
2285 memory associated with the journal.
2287 * message.c (special_inode_name): Add more special inode names
2288 (From Andreas Dilger)
2290 * util.c (fatal_error): Check to make sure the io_manager data
2291 structure is sane before trying to flush the io_channel.
2292 (From Andreas Dilger)
2294 * mtrace.h, super.c, pass2.c: Minor whitespace cleanups, from
2297 * journal.c (e2fsck_journal_fix_bad_inode): Set pctx->ino to the
2300 * problem.c (PR_0_JOURNAL_BAD_INODE): Use pctx->ino instead of
2301 pctx->num when printing the bad journal inode number.
2303 2001-01-11 <tytso@snap.thunk.org>
2305 * pass1.c (process_block): Remove dead code which was never
2308 * iscan.c, unix.c, e2fsck.h: Don't use NOARGS, and use
2309 ext2fs_sync_device() instead of using BLKFLSBUF.
2311 * flushb.c: Don't use NOARGS anymore; everything is STDC these days.
2313 * dirinfo.c, e2fsck.h, emptydir.c, iscan.c, jfs_user.h, journal.c,
2314 message.c, pass1.c, pass1b.c, pass2.c, pass3.c, pass4.c,
2315 pass5.c, problem.h, scantest.c, super.c, swapfs.c: Change
2316 ino_t to ext2_ino_t.
2318 2001-01-09 <tytso@snap.thunk.org>
2320 * problem.c: Fix another broken @F vs @f problem.
2322 2001-01-06 <tytso@snap.thunk.org>
2324 * journal.c, pass1.c, pass1b.c, pass3.c, recovery.c, revoke.c,
2325 super.c, unix.c, util.c: Fix random gcc -Wall complaints.
2327 * jfs_user.h: Use more sophisticated inline handling to allow
2328 building with --enable-gcc-wall
2330 2001-01-03 <tytso@snap.thunk.org>
2332 * pass1.c (e2fsck_pass1): Moved journal inode handling out to its
2333 own block; if the journal inode is not in use, and it
2334 contains data, offer to clear it.
2336 * problem.h, problem.c (PR1_JOURNAL_INODE_NOT_CLEAR): Add new
2339 * problem.c: Modified problem table to use a new abbreviations.
2341 * message.c: Add @j abbreviation for journal, and @v abbreviation
2344 * jfs_user.h: Moved contents of jfs_e2fsck.h into jfs_user.h.
2346 * journal.c (e2fsck_check_ext3_journal): Force a fsck if we remove
2347 the journal stored on a reserved inode. Also force a fsck
2348 if the journal appears to exist while !NEEDS_RECOVERY, and
2349 we forcibly reset the journal.
2351 2001-01-01 <tytso@snap.thunk.org>
2353 * journal.c, pass1.c, super.c, unix.c: Replace use of struct
2354 ext2fs_sb with struct ext2_super_block.
2356 * pass1.c (check_blocks): Remove use of EXT2_HAS_*_FEATURE macros.
2358 2000-12-31 <tytso@snap.thunk.org>
2360 * jfs_compat.h: Remove uneeded header file.
2362 2000-12-30 <tytso@snap.thunk.org>
2364 * malloc.h, mtrace.c: Renamed malloc.h to mtrace.h to avoid
2365 conflicts with the system header file.
2367 * problem.h: Fixed numbering of pass1 error messages; an extra 0
2368 had slipped into some of the numbers. (Pointed out by
2371 * journal.c (e2fsck_journal_fix_corrupt_super): Clean up
2372 unnecessary automatic variable. Add explanatory comment
2373 about the kernel emulation routines. (Suggested by
2376 2000-12-13 Theodore Ts'o <tytso@valinux.com>
2378 * journal.c (e2fsck_check_ext3_journal): Check to make sure the
2379 journal fields are consistent if any of the superblock
2380 fields are set. (Backs out erroneous change made by sct,
2381 pointed out by Andreas.)
2383 * unix.c (main): Clarify coments (no code changes)
2385 * super.c (release_orphan_inodes): Fix spelling typo in error message.
2387 * pass1.c (e2fsck_pass1): Offer to update the filesystem revision
2388 level if we need to set large files flag. Patch from
2391 * super.c (check_super_block): If we have any of the compatibility
2392 flags set, we need to have a revision 1 filesystem. Most
2393 kernels will not check the flags on a rev 0 filesystem
2394 and we may have corruption issues because of the
2395 incompatible changes to the filesystem. Patch from Andreas
2398 * problem.c, problem.h (PR_0_FS_REV_LEVEL, PR_1_FS_REV_LEVEL): Add
2401 2000-12-09 <tytso@snap.thunk.org>
2403 * flushb.c: Fix flushb so that it does something other than waste
2404 disk space when built on systems with modern header files
2405 and add a non-subtle Copyright Licensing restriction so
2406 Yann will remove it from the Debian Distribution. (Now
2407 violates the Debian Free Software Guidelines, on purpose.)
2409 * journal.c (e2fsck_check_ext3_journal): If JFS_DEBUG is defined
2410 at the top level, set the JFS debuging level to 2.
2412 * jfs_e2fsck.h, jfs_user.h: Replaces jfs_compat.h. The jfs.h file
2413 has been moved to the include/linux directory.
2415 * journal.c, revoke.c, recovery.c: Updated files from Stephen to
2416 support the V2 superblock and revoke processing. The
2417 journal.c and revoke.c files are copies from the ext3
2420 * Makefile.in: Added revoke.c to the list of source/object files.
2422 2000-11-16 Theodore Ts'o <tytso@valinux.com>
2424 * pass1b.c: Change routines to use PR_1B_BLOCK_ITERATE when
2425 reporting problems rather than using com_err directly.
2427 * problem.c, problem.h (PR_1B_BLOCK_ITERATE): Add new problem code.
2429 * message.c (expand_percent_expression): Add safety check. If
2430 ctx->str is NULL, print "NULL" instead of dereferencing
2433 * pass1b.c, pass2.c, pass3.c: Change calls to ext2fs_block_iterate
2434 to ext2fs_block_iterate2, to support 64-bit filesizes and
2435 to speed things up slightly by avoiding the use of the
2436 ext2fs_block_iterate's compatibility shim layer.
2438 2000-10-30 <tytso@snap.thunk.org>
2440 * util.c (get_backup_sb): Calculate backup superblock correctly
2441 when the blocksize is > 1k.
2443 2000-10-26 <tytso@snap.thunk.org>
2445 * jfs.h, jfs_compat.h, journal.c: Updated to include the
2446 definition of the new journal superblock format; still
2447 only supports V1 superblocks for now. (From sct)
2449 2000-10-24 <tytso@snap.thunk.org>
2451 * super.c (release_inode_block, release_inode_blocks,
2452 release_orphan_inodes): Add code to deal with truncating
2453 inodes which are still in use (but which are on the orphan
2454 list because they need truncation).
2456 * problem.c, problem.h: Rename PR_0_CLEAR_ORPHAN_INODE to
2457 PR_0_ORPHAN_CLEAR_INODE, and remove
2458 PR_0_ORPHAN_INODE_INUSE.
2460 * journal.c (e2fsck_run_ext3_journal): Add i18n support, and print
2461 a message when the journal is being recovered.
2463 * pass1.c (e2fsck_pass1): Don't check the i_mode field for the
2464 journal inode, if it is in use.
2466 2000-09-12 <tytso@valinux.com>
2469 * flushb.c: Add include of nls-enable.h which is necessary so that
2470 they can compile correctly.
2472 2000-08-22 <tytso@valinux.com>
2474 * unix.c (main): If we're doing a read-only check, skip the
2475 journal playback, but don't abort the e2fsck run.
2477 * super.c (release_orphan_inodes): Fix typo; should do bounds
2478 checking on next_ino instead of ino.
2480 * jfs_compat.h (J_ASSERT):
2481 * journal.c (e2fsck_run_ext3_journal):
2482 * pass3.c (adjust_inode_count): Use fatal_error() instead of exit().
2484 * unix.c: Use fatal_error() instead of exit() whenever possible.
2485 Also fix the fsck exit codes so that we use FSCK_USAGE
2486 when it is appropriate. Rename global_signal_ctx to
2487 e2fsck_global_ctx and let it be exported globally.
2489 * util.c (fatal_error): Try to flush the I/O manager before
2492 2000-08-20 <tytso@valinux.com>
2494 * journal.c (e2fsck_journal_load): Fix **nasty** bug which caused
2495 e2fsck_check_ext3_journal to smash the journal because
2496 journal->j_transaction_sequence wasn't getting
2499 * journal.c: (recover_ext3_journal, e2fsck_run_ext3_journal): Move
2500 call to e2fsck_clear_recover from recover_ext3_journal to
2501 after the filesystem has been closed and reopened.
2502 Otherwise, the superblock in the filesystem handle will
2503 probably be stale, and will overwrite the newer version of
2504 the superblock written by the log recovery.
2506 * message.c (expand_inode_expression): Add support for %Iu and %Ig
2508 * problem.h (PR_0_CLEAR_ORPHAN_INODE): Add new problem code.
2510 * super.c (release_orphan_inodes, release_inode_block,
2511 release_inode_blocks): Update the block group descriptor
2512 counts when freeing the orphan inode. Use
2513 PR_0_CLEAR_ORPHAN_INODE to report when we clear an orphan.
2515 * journal.c (e2fsck_run_ext3_journal): Fix a bug where we
2516 attempted to reopen the filesystem using the device name
2517 instead of the filesystem name.
2519 2000-08-18 <tytso@valinux.com>
2521 * Makefile.in: Update the make dependencies
2523 * problem.c, problem.h: Add the problem codes:
2524 PR_0_ORPHAN_ILLEGAL_BLOCK_NUM,
2525 PR_0_ORPHAN_ALREADY_CLEARED_BLOCK,
2526 PR_0_ORPHAN_ILLEGAL_HEAD_INODE,
2527 PR_0_ORPHAN_ILLEGAL_INODE, PR_0_ORPHAN_INODE_INUSE
2529 * super.c (release_inode_blocks, release_orphan_inodes,
2530 check_super_block): Add support for clearing orphaned
2531 inodes from the unmounted filesystem.
2533 * journal.c (e2fsck_recover_ext3_journal): Remove the last orphan
2534 check; this is now handled in check_super_block ---
2535 non-journaled filesystems can use the orphan list in the
2536 future. Also, move the the re-opening of the filesystem
2537 to e2fsck_run_ext3_journal().
2539 2000-07-12 Andreas Dilger <adilger@turbolinux.com>
2541 * journal.c: implement loading of ext3 journal for recovery code
2543 * problem.c (fix_problem): return answer from PR_AFTER_CODE to caller.
2544 Add journal problems.
2546 * recovery.c (journal_recover): user-space ext3 journal recovery code
2548 * unix.c (main) : check journal and do recovery in separate steps
2550 2000-08-07 <tytso@snap.thunk.org>
2552 * unix.c (calc_percent): Make sure that we don't take a floating
2553 exception if the max value is zero. (should normally
2554 never happen, but...)
2556 2000-07-13 <tytso@valinux.com>
2558 * Release of E2fsprogs 1.19
2560 2000-07-06 Theodore Ts'o <tytso@valinux.com>
2562 * unix.c (check_if_skip): Modify algorithm for checking
2563 s_max_mnt_count to match with the kernel. (If
2564 s_max_mnt_count is negative, ignore the mnt_count check.)
2566 * unix.c (e2fsck_update_progress): Adjust the width of the
2567 progress bar dynamically, based on the filesystem name
2568 that we need to display.
2570 * unix.c (main): If the ext3 needs_recovery flag is set, call
2571 e2fsck_run_ext3_journal() and then restart the e2fsck run.
2573 * journal.c (e2fsck_run_ext3_journal): New file which contains
2574 logic to recover the ext3 journal. This version relies on
2575 the kernel being able to mount the filesystem in order to
2578 2000-07-05 Theodore Ts'o <tytso@valinux.com>
2580 * unix.c (e2fsck_update_progress): Only save and check the last
2581 percentage after multiplying it by 10, nor 1000, since we
2582 only need to save values to a tenth of a percent (and the
2583 percentage is already from 0 .. 100%, not 0 .. 1).
2584 Also, re-arrange the logic so that we do the time
2585 check only after doing the percentage check, and we
2586 only advance the spinner if we're about to display it.
2588 2000-07-04 Theodore Ts'o <tytso@valinux.com>
2590 * pass1.c (e2fsck_pass1): Check to see if the ext3 s_last_orphan
2591 field is set; if so, clear it, so that ext3 mounting code
2592 won't get confused by the fact that we've cleared out the
2595 2000-06-10 Theodore Ts'o <tytso@valinux.com>
2597 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Add error
2598 checking for a "should never happen case".
2600 * problem.c, problem.h (PR_5_COPY_IBITMAP_ERROR,
2601 PR_5_COPY_BBITMAP_ERROR): Add new error codes.
2603 2000-05-27 Theodore Ts'o <tytso@valinux.com>
2605 * pass1.c (pass1, check_size): Apply patch from Chris Wedgewood
2606 (cw@foof.org) which checks to see if special devices have
2607 a non-zero size, and deals with it.
2609 * problem.c, problem.h (PR1_SET_NONZSIZE): Add new problem code.
2611 2000-05-18 Theodore Ts'o <tytso@valinux.com>
2613 * Makefile.in (install): Create a symbolic link for fsck.ext3 as
2616 2000-05-08 Theodore Ts'o <tytso@valinux.com>
2618 * problem.c, problem.h (PR_0_HURD_CLEAR_FILETYPE): Add new problem
2621 * super.c (check_super_block): If the OS type in the superblock is
2622 the Hurd, check to see if the filetype feature is set, and
2623 offer to clear it if so. This needs to be done since the
2624 Hurd doesn't properly support the filetype feature.
2625 (And since the hurd allows the transmogrification of files
2626 to special files and vice versa --- for no good reason
2627 that I can understand --- it can't support the filetype
2628 feature for the forseeable future, either.)
2630 2000-04-03 Theodore Ts'o <tytso@valinux.com>
2632 * unix.c: For platforms that don't define optarg.h, manually
2633 define optarg and optind.
2635 2000-03-20 Theodore Ts'o <tytso@valinux.com>
2637 * pass1.c (check_immutable, e2fsck_pass1_check_device_inode):
2638 Check for the append-only as well as the immutable flag.
2640 * problem.c (PR_1_SET_IMMUTABLE): Adjust message to include
2641 append-only flag. Fix comment for compression flag.
2643 2000-02-12 <tytso@snap.thunk.org>
2645 * unix.c (e2fsck_update_progress): Limit the number of updates to
2646 the progress bars to 8 times a second. This allows a 9600
2647 baud console link to keep up.
2649 2000-02-11 <tytso@snap.thunk.org>
2651 * unix.c (main): If compression is enabled on the filesystem,
2652 print a warning message (for now).
2654 * message.c: Add new compression shortcut: @c == compress
2656 * problem.c, problem.h (PR_1_COMPR_SET): Add new error code.
2658 * pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag
2659 set, check to see if the filesystem supports compression.
2660 If it does pass this information down to process_block()
2661 so it can treat the compressed block flag words
2662 correctly. If not, offer to clear the flag, since it
2664 (process_block): If an inode has the compressed inode flag
2665 set, allow EXT2FS_COMPRESSED_BLKADDR.
2667 * pass1b.c (process_pass1b_block, delete_file_block,
2669 * pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to
2670 see if the block can be skipped.
2672 2000-02-08 <tytso@snap.thunk.org>
2674 * util.c: Make resource tracking message more concise.
2677 * pass1.c (mark_table_blocks, e2fsck_pass1): Remove
2678 ctx->block_illegal_map, since it's not needed by pass1,
2679 and pass1b has been modified to calculate it manually if
2680 needed. This reduces the memory footprint needed by e2fsck.
2682 * pass1b.c (check_if_fs_block): New static function which returns
2683 whether or not a block overlaps with filesystem metadata.
2684 This replaces consulting the block_illegal_map bitmap.
2686 * Makefile.in: Call sync after finishing building all in this
2689 * unix.c (PRS): sync the filesystem before trying to use
2690 BLKFLSBUF, to minimize the chance of causing dirty blocks
2693 * e2fsck.h: Manually define BLKFLSBUF if not defined, and we're on
2694 a Linux/i386 system.
2696 * pass3.c (check_directory): Only do the loop detection algorithm
2697 if we've searched over 2048 parent directories and haven't
2698 found the end yet. This means that in the common case, we
2699 don't allocate or clear the inode_loop_detection bitmap,
2700 which for large systems, merely clearing the bitmap for
2701 each directory was turning out to be quite expensive.
2702 Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for
2703 identifying this problem.
2705 2000-02-06 Theodore Ts'o <tytso@valinux.com>
2707 * badblocks.c, e2fsck.h, ehandler.c, emptydir.c, extend.c,
2708 flushb.c, iscan.c, message.c, pass1.c, pass1b.c, pass3.c
2709 pass4.c, pass5.c, problem.c, scantest.c, swapfs.c,
2710 unix.c, util.c: Add Internationalization support as
2711 suggested by Marco d'Itri <md@linux.it>.
2713 2000-02-02 Theodore Ts'o <tytso@valinux.com>
2715 * e2fsck.h, flushb.c, scantest.c: Remove uneeded include of
2718 2000-01-18 Theodore Ts'o <tytso@valinux.com>
2720 * Makefile.in: Since LIBUUID can sometimes include "-lsocket"
2721 we need a separate DEPLIBUUID that can be used in
2722 Makefile's dependency rules.
2724 1999-11-23 <tytso@valinux.com>
2726 * e2fsck.8.in: Update language about where to find a backup
2729 1999-11-19 <tytso@valinux.com>
2731 * pass1.c (process_inodes): Add shortcut handling; if
2732 process_inodes_count is zero, return right away, to avoid
2733 calling qsort with a non-positive count.
2735 * message.c (safe_print): Fix to properly display ^A, ^B, etc. and
2736 to print Delete as ^?
2738 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
2739 the source directory.
2741 1999-11-10 <tytso@valinux.com>
2743 * Release of E2fsprogs 1.18
2745 1999-11-10 <tytso@valinux.com>
2747 * problem.c (fix_problem): Support a new flag, PR_PREEN_NO which
2748 means the answer is assumed to be no in preen mode. This
2749 is now used in the PR_1_SET_IMMUTABLE code, so that in
2750 preen mode we ignore these inodes and just print a warning
2753 1999-11-09 <tytso@valinux.com>
2755 * pass1.c (e2fsck_pass1): If the filesystem does not support
2756 imagic inodes, if an inode has the imagic flag set, offer
2757 to clear the imagic flag. If a valid device/fifo/socket
2758 has the immutable flag set, call the new helper function
2759 check_immutable() to offerto clear the immutable flag.
2761 * pass2.c (check_filetype): Use the new ext2_file_type() helper
2762 function instead of calculating the file_type information
2765 * pass3.c (e2fsck_reconnect_file): When adding a link to
2766 lost+found, calculate the filetype information so that
2767 ext2fs_link() can use the information if applicable.
2768 (get_lost_and_found): Create the /lost+found directory
2769 with the correct filetype information if applicable.
2771 * util.c (ext2_file_type), e2fsck.h: New function which returns
2772 the directory entry file type information given the
2775 * problem.c, problem.h: Added new problem codes PR_1_SET_IMAGIC
2776 and PR_1_SET_IMMUTABLE.
2778 1999-11-07 <tytso@valinux.com>
2780 * pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it,
2781 to prevent it from getting freed twice.
2783 1999-11-06 <tytso@valinux.com>
2785 * unix.c (main): Close the filesystem before freeing the context,
2786 so that in the event of a free()-related segmentation
2787 violation, the filesystem is properly closed and written
2790 1999-10-27 <tytso@valinux.com>
2792 * e2fsck.c (e2fsck_reset_context): When freeing
2793 ctx->inode_reg_map, we weren't zero'ing
2794 ctx->inode_reg_map, which could cause a segfault later on
2797 1999-10-26 <tytso@valinux.com>
2799 * problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
2800 matches the standard convention).
2802 1999-10-26 <tytso@valinux.com>
2804 * Release of E2fsprogs 1.17
2806 1999-10-26 <tytso@valinux.com>
2808 * message.c (safe_print): Make safe_print take an char instead of
2809 an unsigned char to fix gcc warnings.
2811 1999-10-25 <tytso@valinux.com>
2813 * util.c: For NT portability, don't redefine getchar(), since
2814 stdio defines that. Instead we introduce a new
2815 abstract macro read_a_char() which is #defined to the
2816 right function as necessary.
2818 * problem.c, problem.h (PR_2_NULL_NAME): Add new problem code.
2820 * pass2.c (check_dir_block): Require that the length of the
2821 directory entry be at least 12 bytes. Check to see if the
2822 filename is zero-length, and flag that as an error.
2824 1999-10-22 <tytso@valinux.com>
2826 * Release of E2fsprogs 1.16
2828 1999-10-22 <tytso@valinux.com>
2830 * pass2.c (check_filetype): If the filetype filesystem feature is
2831 not set, and a directory entry has a dirent feature, offer
2832 to clear it (since 2.0 kernels will do complain will
2833 interpret it as a very large name length field).
2835 * problem.c (PR_2_CLEAR_FILETYPE): Add new problem code.
2837 1999-10-21 <tytso@valinux.com>
2839 * e2fsck.8.in: Update man page to use a more standard format (bold
2840 option flags and italicized variables), as suggested by
2841 Andreas Dilger (adilger@enel.ucalgary.ca)
2843 * pass4.c (e2fsck_pass4): If an inode is set in the
2844 inode_imagic_map bitmap, don't check to see if it is
2845 disconnected from the inode tree (because it almost
2846 certainly will be). Free inode_imagic_map at the end of
2849 * pass2.c (check_dir_block, check_filetype): If the FILETYPE
2850 feature is set, check the directory entry's filetype
2851 information field, and fix/set it if necessary.
2852 (e2fsck_pass2): Free the inode_reg_map bitmap at the end
2855 * pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
2856 information for inode_reg_map and inode_imagic_map, which
2857 indicates which inodes are regular files and AFS inodes,
2859 Since only the master superblock is written during a
2860 restart, force that superblock to be used after a restart;
2861 otherwise changes to the block group descriptors end up
2864 * problem.c, problemP.h: If e2fsck is run -n, make def_yn variable
2865 be 0 for "no". Add support for a new flag, PR_NO_NOMSG,
2866 which supresses the problem message if e2fsck is run with
2869 * problem.c, problem.h (PR_2_SET_FILETYPE, PR_2_BAD_FILETYPE): Add
2872 * message.c (expand_dirent_expression): Add support for %dt which
2873 prints the dirent type information.
2875 * e2fsck.c (e2fsck_reset_context): Free new bitmaps (inode_reg_map
2876 and inode_imagic_map).
2878 * e2fsck.h (e2fsck_t): Add new inode_reg_map and inode_magic_map
2879 to the context structure.
2881 1999-09-24 <tytso@valinux.com>
2883 * unix.c (PRS), util.c (ask_yn): Add #ifdef's to make
2884 e2fsprogs easier to port to non-Unix platforms.
2886 1999-09-07 <tytso@valinux.com>
2888 * pass3.c (adjust_inode_count): Fix bug where we didn't keep the
2889 internal and external inode counts in sync when we
2890 decremented an inode whose link count was already zero.
2891 Now we skip incrementing or decrementing both link counts
2892 if we would cause an overflow condition.
2893 (expand_dir, expand_dir_proc): Change where we update the
2894 inode block count and size files so that the block count
2895 field is updated correctly when we create an indirect block.
2897 1999-08-05 <tytso@valinux.com>
2899 * super.c (check_super_block): Check to see whether the
2900 inodes_per_group value in the superblock is insanely too
2903 1999-08-02 <tytso@valinux.com>
2905 * pass1b.c (clone_file_block): Don't clear the dup_map flag if
2906 the block also shares data with the fs metadata when
2907 the count drops to 1, since the block should still be
2908 cloned, as fs metadata isn't included in the count.
2910 1999-07-18 Theodore Ts'o <tytso@valinux.com>
2912 * Release of E2fsprogs 1.15
2914 1999-07-19 <tytso@valinux.com>
2916 * unix.c (usage): Add minimalist emergency help to the usage
2919 1999-07-18 <tytso@valinux.com>
2921 * unix.c: Add support for calculating a progress bar if the -C0
2922 option is given. The function e2fsck_clear_progbar()
2923 clears the progress bar and must be called before any
2924 message is issued. SIGUSR1 will enable the progress bar,
2925 and SIGUSR2 will disable the progress bar. This is used
2926 by fsck to handle parallel filesystem checks. Also, set
2927 the device_name from the filesystem label if it is
2930 * e2fsck.h: Add new flags E2F_FLAG_PROG_BAR and
2931 E2F_FLAG_PROG_SUPRESS. Add new field in the e2fsck
2932 structure which contains the last tenth of a percent
2933 printed for the user.
2935 * message.c (print_e2fsck_message): Add call to
2936 e2fsck_clear_progbar().
2938 * pass1.c (e2fsck_pass1):
2939 * pass2.c (e2fsck_pass2):
2940 * pass3.c (e2fsck_pass3):
2941 * pass4.c (e2fsck_pass4):
2942 * pass5.c (e2fsck_pass5): Add call to e2fsck_clear_progbar when
2943 printing the resource tracking information.
2945 * pass5.c (check_block_bitmaps, check_inode_bitmaps): If there is
2946 an error in the bitmaps, suppress printing the progress
2947 bar using the suppression flag for the remainder of the
2948 check, in order to clean up the display.
2950 1999-06-30 <tytso@valinux.com>
2952 * unix.c (check_mount): Clean up the abort message displayed when
2953 the filesystem is mounted and either stdout or stdin isn't
2956 1999-06-25 <tytso@valinux.com>
2959 * pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
2960 pass1_check_directory, e2fsck_use_inode_shortcuts): Make
2961 pass1_* be private static functions, and create new
2962 function e2fsck_use_inode_shortcuts which sets and clears
2963 the inode shortcut functions in the fs structure.
2966 * pass2.c (e2fsck_process_bad_inode): Make process_bad_inode() an
2969 * pass4.c (e2fsck_pass4): Call e2fsck_process_bad_inode to check
2970 if a disconnected inode has any problems before
2971 connecting it to /lost+found. Bug and suggested fix by
2972 Pavel Machek <pavel@bug.ucw.cz>
2974 1999-06-21 <tytso@valinux.com>
2976 * unix.c (main): Add missing space in the disk write-protected
2979 1999-05-22 <tytso@rsts-11.mit.edu>
2981 * problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem
2984 * super.c (check_super_block): Add check to make sure the total
2985 number of inodes is sane, since this can be calculated
2986 from the number of groups times the number of inodes per
2987 group. Offer to correct it if it is incorrect.
2989 1999-03-19 <tytso@rsts-11.mit.edu>
2991 * pass5.c (check_block_end): Fix fencepost condition where when
2992 clearing the block padding we were missing the last position
2995 1999-05-17 <tytso@rsts-11.mit.edu>
2997 * unix.c (reserve_stdio_fds): Add safety check in case
2998 reserve_stdio_fds couldn't open /dev/null.
3000 1999-03-14 Theodore Ts'o <tytso@rsts-11.mit.edu>
3002 * util.c (print_resource_track): Use mallinfo if present to get
3003 more accurate malloc statistics.
3005 * pass3.c (get_lost_and_found): Check to see if lost+found is a
3006 plain file; if so, offer to unlink it.
3008 * problem.c, problem.h (PR_3_LPF_NOTDIR): Add new problem code.
3010 1999-03-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3012 * problem.c: Fix problem message for PR_1_BAD_GROUP_DESCRIPTORS so
3013 that the block group number is printed. Add new prompt,
3016 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3018 * Release of E2fsprogs 1.14
3020 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3022 * message.c (safe_print): New function which prints strings,
3023 converting non-printable characters using the '^' and
3024 M-notation. This function is now used to print directory
3025 name entries and pathnames.
3027 Mon Jan 4 02:28:59 1999 Theodore Y. Ts'o <tytso@mit.edu>
3029 * unix.c (main): Reset the context before calling ext2fs_close(),
3030 to avoid referencing already freed memory.
3032 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
3034 * Release of E2fsprogs 1.13
3036 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
3038 * Makefile.in: Updated dependencies.
3040 1998-11-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
3042 * pass3.c (get_lost_and_found): If the filesystem is not opened
3043 read-only, then force /lost+found to be created if it is
3046 * problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen
3049 1998-10-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
3051 * unix.c (main): Move ext2fs_close() after e2fsck_free_context()
3052 since e2fsck_free_context may reference data in ctx->fs.
3054 * e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL
3055 before checking ctx->fs->dblist.
3057 1998-10-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3059 * pass1.c (e2fsck_pass1): Use the device check subroutine on
3060 FIFO's and Socket's, so that we catch bogus immutable inodes.
3062 * pass2.c (process_bad_inode): Process bad socket and fifo's.
3064 * problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
3067 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
3069 * problem.c: Add PR_3_NO_DIRINFO error code.
3071 * super.c (check_super_value): Rename min and max to min_val and
3072 max_val to avoid possible cpp macro conflicts.
3074 * pass4.c (e2fsck_pass4): Rename max to maxgroup, to avoid
3075 possible cpp macro conflicts.
3077 * pass3.c (e2fsck_pass3): Rename max to maxdirs, to avoid possible
3078 cpp macro conflicts.
3079 (check_directory): Fix logic to avoid possible core dump
3080 in the case of ext2fs_get_dir_info returning NULL. (By
3081 the time we get here, it should never happen, but...).
3082 Also simply/streamline the control flow of the function.
3084 1998-08-17 Theodore Ts'o <tytso@rsts-11.mit.edu>
3086 * unix.c (check_if_skip): Move the "not cleanly mounted" check
3087 ahead of the maximal mount and too long since checked tests.
3088 (reserve_stdio_fds): Make sure 0,1,2 file descriptors are
3089 open, so that we don't open the filesystem using the same
3090 file descriptor as stdout or stderr.
3092 1998-08-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
3094 * pass2.c (e2fsck_pass2): Fix the progress accounting so that we
3097 * pass3.c (e2fsck_pass3): Change progress accounting to be
3098 consistent with the other e2fsck passes.
3100 * e2fsck.c (e2fsck_run): At the end of each pass, call the
3101 progress function with the pass number set to zero.
3103 * unix.c (e2fsck_update_progress): If the pass number is zero,
3104 ignore the call, since that indicates that we just want to
3105 deallocate any progress structures.
3107 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3109 * Release of E2fsprogs 1.12
3111 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
3113 * unix.c (main): Fix typo in checking the incompat feature set; it
3114 should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.
3116 1998-07-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
3118 * badblocks.c (test_disk): Don't clear the existing bad blocks
3119 list when using e2fsck -c, since it may cause blocks with
3120 marginal errors to be dropped from the bad blocks list.
3122 Mon Jul 6 10:32:11 1998 Theodre Ts'o <tytso@lurch.mit.edu>
3124 * pass1.c (e2fsck_pass1): Use ext2fs_sb structure for
3125 compatibility with older kernels.
3127 1998-06-25 Theodore Ts'o <tytso@rsts-11.mit.edu>
3129 * unix.c (e2fsck_update_progress): Remove unused variables.
3131 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
3133 * pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
3134 collision with LFS API.
3136 * pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
3137 properly initialized.
3138 (e2fsck_pass1): Don't allow the the boot loader inode to
3139 be a directory (clear the inode mode field if so).
3141 1998-05-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
3143 * unix.c (PRS): Added new option -C, which causes e2fsck to print
3144 progress updates so that callers can keep track of the
3145 completion progress of e2fsck. Designed for use by
3146 progress, except for -C 0, which prints a spinning report
3147 which may be useful for some users.
3149 * pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
3150 scheme (useful for larger filesystems).
3152 * e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
3153 progress reporting functions.
3155 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
3157 * pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
3158 appropriate return type for comparison functions for qsort.
3160 * e2fsck.h: Add #ifdef protection for unistd.h
3162 * super.c: Remove header files already included by e2fsck.h
3164 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
3166 * dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
3167 size of the memory to be resized to ext2fs_resize_mem().
3169 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
3171 * Makefile.in: Change to use new installation directory variables
3172 convention. Fix uninstall rules to take $(DESTDIR) into
3173 account. Remove cat8dir from the installdirs target,
3174 since modern man package don't necessarily put the cat
3175 directory in /usr/man/cat?.
3177 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
3179 * super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
3180 extern in e2fsck.h to prevent -Wall warnings.
3182 * pass4.c (e2fsck_pass4): Remove unused variable 'j'.
3184 1998-03-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
3186 * super.c (check_super_block): Fix broken superblock sanity check
3187 when calculating blocks_per_group if s_log_frag_size !=
3188 s_log_block_size. Since we don't support fragments, this
3189 isn't a bug deal, but it's good to get it fixed.
3191 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
3193 * unix.c: Fix bug in check of feature set, to make sure we can
3194 really fix this filesystem.
3196 * problem.h: Make blkcount type to be of type blkcnt_t. Make the
3197 num field be a 64 bit type. Add the problem code
3198 PR_1_FEATURE_LARGE_FILES
3200 * problem.c: Add table entry for the problem code
3201 PR_1_FEATURE_LARGE_FILES.
3203 * pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
3204 a problem for directory inodes. (Since it is also
3205 i_size_high now.) If there are no large_files, then
3206 clear the LARGE_FLAG feature flag. If there are
3207 large_files, but the LARGE_FLAG feature flag is not set,
3208 complain and offer to fix it.
3209 (check_blocks): Add support to deal with non-directory
3210 inodes that have i_size_high set (i.e., large_files).
3211 Don't give an error if a directory has preallocated
3212 blocks, to support the DIR_PREALLOC feature.
3213 (process_block, process_bad_block): The blockcnt variable
3214 is a type of blkcnt_t, for conversion to the new
3217 * pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
3218 a problem for directory inodes. (Since it is also
3221 * message.c (expand_inode_expression): Print a 64-bits of the
3222 inode size for non-directory inodes. (Directory inodes
3223 can only use a 32-bit directory acl size, since
3224 i_size_high is shared with i_dir_acl.) Add sanity check
3225 so that trying to print out the directory acl on a
3226 non-directory inode will print zero.
3227 (expand_percent_expression): %B and %N, which print
3228 pctx->blkcount and pctx->num, can now be 64 bit
3229 variables. Print them using the "%lld" format if
3230 EXT2_NO_64_TYPE is not defined.
3232 * e2fsck.h: Add the large_flagsfield to the e2fsck context.
3234 * e2fsck.c (e2fsck_reset_context): Clear the large_flags
3237 Sun Mar 8 23:08:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3239 * pass3.c (fix_dotdot_proc):
3240 * pass2.c (check_dot, check_dotdot, check_name, check_dir_block):
3241 * message.c (expand_dirent_expression): Mask off the high eight
3242 bits of the directory entry's name_len field, so that it
3243 can be used for other purposes.
3245 Fri Feb 27 00:01:39 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3247 * e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
3248 include EXT2_FLAG_RESTART anymore, we need to adjust this
3249 routine so that it *does* return in the case of it seeing
3252 * pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
3253 done callback function, which may set context abort
3254 flags. So we need to test the context abort flags after
3255 we call ext2_get_next_inode().
3256 (process_inodes): If we abort due out of process_inodes,
3257 do a clean exit by breaking out of the for loop instead of
3260 * e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
3261 considered a SIGNAL mask (i.e., requiring an immediate
3262 abort of processing to restart). FLAG_RESTART just means
3263 that we want to restart once pass 1 is complete.
3265 Tue Feb 24 15:19:40 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3267 * Change the progress function to return an integer; if returns 1,
3268 then the progress function is expected to have set the
3269 e2fsck context flag signalling a user abort, and the
3270 caller should also initiate a user abort.
3272 Tue Feb 17 19:03:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3274 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
3275 end_problem_latch() unless there was actually a problem
3276 latched. Simplifies semantics of the latch processing.
3278 Mon Feb 16 17:31:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3280 * e2fsck.h: Add new field, priv_data to the e2fsck context
3281 structure. It should be used by callers of the e2fsck
3282 functions only, and not by anything in e2fsck itself.
3284 Mon Feb 7 17:31:04 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3286 * super.c: Instead of call ext2fs_get_device_size(), define and call
3287 e2fsck_get_device_size(). (This function may be stubbed
3288 out in special versions of e2fsck.)
3290 * pass3.c, pass4.c: Remove extra calls to the progress function
3291 that weren't needed.
3293 * mke2fs.8.in: Update man page to note that the format of the bad
3294 block file is the same as the one generated by badblocks.
3296 Sun Feb 1 07:57:14 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3298 * dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
3300 * e2fsck.h: Include <time.h> since it is needed
3302 * super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
3305 Tue Jan 20 15:37:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3307 * unix.c (main): In the case where the filesystem revision is too
3308 high, print the message about the superblock possibly
3311 * e2fsck.8.in: Add expanded comments about how the -b option
3314 Sat Jan 17 13:02:16 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3316 * e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
3317 the ext2-specific header files are in a flat directory.
3319 * dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
3320 super.c, swapfs.c, unix.c: Explicitly cast all assignments
3321 from void * to be compatible with C++.
3323 Tue Jan 6 11:30:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
3325 * unix.c (sync_disk): Remove sync_disk and calls to that function,
3326 since ext2fs_close() now takes care of this.
3328 Mon Dec 29 14:45:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3330 * pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
3331 ehandler.c, unix.c: Change use of private to be priv_data,
3332 to avoid C++ reserved name clash.
3334 Fri Nov 28 09:30:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3336 * dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
3337 of e2fsck_get_num_dirs, which has been removed.
3339 Tue Nov 25 15:54:35 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3341 * Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
3342 to compile and install flushb.
3344 Mon Nov 24 06:48:00 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3346 * pass1.c (e2fsck_pass1_check_device_inode): For now, only check
3347 to make sure the extra i_blocks in a device are cleared if
3348 the immutable flag is set.
3350 * util.c (print_resource_track): Fix typo which caused the
3351 time/resource tracking to print "Pass 1 :" instead of
3354 Thu Nov 20 16:02:23 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3356 * pass3.c (expand_directory): Fix bug which could cause core dump
3357 when expanding the directory, and the bitmaps hadn't yet
3358 been read in. Also, only use ext2fs_write_dir_block when
3359 writing a directory block, not when writing out a fresh
3362 Wed Nov 19 16:15:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3364 * pass1.c (process_bad_block): Fix bug where first_block wasn't
3365 getting incremented, which caused user to get a
3366 "Programming error?" warning if there was a bad block in a
3367 non-primary superblock/group_descriptor. Also fixed
3368 another bug so that ext2fs_bg_has_super() is consulted, to
3369 avoid problems when using a filesystem with the
3370 sparse_groups option set and there are bad blocks at the
3371 beginning of a group which doesn't have a superblock.
3373 Thu Nov 6 16:10:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3375 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the
3376 progress indicator function.
3378 * pass1.c (scan_callback): Add call to the progress feedback
3379 function (if it exists).
3381 Tue Nov 4 09:45:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3383 * super.c (check_super_block): Skip the device size check if the
3384 get_device_size returns EXT2_EXT_UNIMPLEMENTED.
3386 * iscan.c (main): Don't use fatal_error() anymore.
3388 * pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
3389 calling fatal_error(0).
3391 * problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
3392 PR_3_NO_ROOT_INODE_ABORT): New problem codes.
3394 * problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
3396 * problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
3398 * problemP.h: New file which separates out the private fix_problem
3401 * util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
3402 swapfs.c util.c: allocate_memory() now takes a e2fsck
3403 context as its first argument, and rename it to be
3404 e2fsck_allocate_memory().
3406 Mon Nov 3 14:35:29 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3408 * unix.c (main): Add a special case check for the error code EROFS
3409 and display an appropriate error message for this case.
3411 * [lots of files]: Change ext2fs_read_inode, ext2fs_write_inode
3412 to take the e2fsck context as their first argument.
3413 Change dir_info.c routines to take an e2fsck_context,
3414 renamed them to start with e2fsck_ to avoid namespace
3415 issues, and changed them to store the directory
3416 information inside the e2fsck context.
3417 Added e2fsck_run() which calls all of the e2fsck passes in
3418 the correct order, and which handles the return of abort
3419 codes. Added abort processing, both via setjmp/longjmp
3420 and via flags in the e2fsck context. Use a flag in the
3421 e2fsck context instead of the restart_e2fsck global
3422 variable. Change uses of free and malloc to
3423 ext2fs_free_mem and ext2fs_get_mem.
3425 Fri Oct 31 01:12:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3427 * pass1.c, pass3.c: Rename new error codes to _ET_ in them for
3430 Sat Oct 25 00:10:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3432 * pass3.c (get_lost_and_found): Check error return of
3433 EXT2_FILE_NOT_FOUND instead of ENOTDIR
3435 * pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
3438 Fri Oct 24 00:12:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3440 * unix.c (PRS): Make the variable which getopt returns into be
3441 an int, so that it won't lose on platforms where char is
3444 * pass1b.c (clone_file): Fix bug in error reporting in the case
3445 where cs.errcode is non-zero.
3447 Sun Oct 19 21:12:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3449 * pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
3450 RESOURCE_TRACK around code which uses init_resource_track
3451 and print_resource_track. (Not all systems have timeval)
3453 * super.c: Remove excess #includes which are not necessary.
3455 * e2fsck.h: Add #ifdef's for HAVE_SYS_TYPES_H and HAVE_SYS_TIME_H
3457 Fri Oct 3 13:40:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3459 * pass*.c, super.c: Massive changes to avoid using printf and
3460 com_err routines. All diagnostic messages are now routed
3461 through the fix_problem interface.
3463 Sat Sep 6 17:13:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3465 * pass2.c (check_dir_block): Check for duplicate '.' and '..'
3468 * problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
3471 Tue Sep 2 09:04:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3473 * problem.c: Added new problem codes for some of the
3474 superblock corruption checks, and for the pass header
3475 messages. ("Pass 1: xxxxx")
3477 * util.c (print_resource_track): Now takes a description
3480 Mon Aug 25 10:23:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3482 * super.c, unix.c, e2fsck.c: New files to separate out the
3483 operating-specific operations out from e2fsck.c.
3484 e2fsck.c now contains the global e2fsck context management
3485 routines, and super.c contains the "pass 0" initial
3486 validation of the superblock and global block group
3489 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
3490 (nearly) all global variables and moved them to the e2fsck
3493 * problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
3494 PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS,
3495 PR_0_BLOCKS_PER_GROUP, PR_0_FIRST_DATA_BLOCK
3497 Thu Aug 14 10:55:21 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3499 * message.c: Add compression for the word "Illegal"
3501 * problem.c: Added entries for PR_2_BAD_CHAR_DEV and
3504 Wed Aug 13 09:55:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3506 * pass1.c (pass1, check_device_inode), pass2.c
3507 (process_bad_inode): Use a more stringent test for a valid
3510 Sun Aug 10 18:58:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3512 * e2fsck.c (check_mount): Add stronger warning message about the
3513 perils of running e2fsck on a mounted filesystem.
3515 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3517 * Release of E2fsprogs 1.11
3519 Thu Jun 12 00:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3521 * pass1.c (mark_table_blocks): Mark the superblock and group
3522 descriptor blocks first, so that any conflicts between
3523 these and the bitmap or inode table blocks is noticed.
3525 * problem.c: Fix message printed out when a block or inode bitmap
3526 conflicts with other fs data, has the correct group number
3529 Tue Jun 10 12:07:37 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3531 * pass2.c (pass2): Check the error return from ext2fs_dblist_iterate.
3533 Thu May 8 22:45:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3535 * e2fsck.8.in: Fix minor typos and grammer oops found by Bill
3536 Hawes (whawes@star.net).
3538 * badblocks.c (read_bad_blocks_file): Pass the blocksize to the
3539 bad blocks command so that all of the filesystem gets
3540 tested in the case where the blocksize 2048 or 4096.
3542 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
3544 * Release of E2fsprogs version 1.10
3546 Mon Apr 21 22:43:08 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3548 * pass1b.c (pass1b): While scanning for inodes, simply skip inodes
3549 where ext2fs_get_next_inode returns the
3550 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE error.
3552 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3554 * Release of E2fsprogs version 1.09

3558 * Release of E2fsprogs version 1.08
3560 Thu Apr 10 13:51:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3562 * pass1b.c (clone_file_block): If we clone a directory, we need to
3563 update the dblist entry so that we check (and correct) the
3564 right directory block.
3566 Sun Apr 6 09:13:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3568 * pass1.c (process_block): Don't clear blocks references to
3569 filesystem metadata; let pass 1B handle this case.
3571 * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
3573 * pass1b.c (pass1d): Deal with a block which is shared with
3574 filesystem metadata.
3576 * e2fsck.h: Make block_illegal_map be a global variable
3578 Sat Apr 5 11:51:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3580 * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
3582 (get_backup_sb): New function which attempts to obtain the
3583 correct backup superblock (if possible).
3585 Fri Apr 4 10:46:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3587 * e2fsck.c (main): Check the version of the library, and warn if
3588 the library is out of date; this happens generally due to
3589 users who manually install e2fsprogs.
3591 * pass1.c (pass1_get_blocks): If the passed in inode number for
3592 get_blocks isn't what we're expecting pass back
3593 EXT2_ET_CALLBACK_NOT_HANDLED.
3595 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
3597 * Release of E2fsprogs version 1.07
3599 Tue Mar 11 10:31:47 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3601 * icount.c: New file which implements an inode count abstraction.
3602 This significantly reduces amount of memory needed to
3603 check really large filesystems.
3605 * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
3608 Fri Mar 7 08:28:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3610 * dirinfo.c (dir_info_iter): New function which allows iteration
3611 over the directories in the dir_info map.
3613 * pass3.c (pass3, check_directory): Speed up pass 3 by iterating
3614 over all directories in the dir_info structure, instead of
3615 iterating all inodes looking for directories, and then
3616 looking up the directories using get_dir_info().
3618 Sat Feb 1 11:33:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3620 * pass1.c (pass1, process_block):
3621 * pass2.c (pass2): Use the ext2_dblist abstraction instead of
3622 manual code to manage the directory block list information.
3624 * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
3625 (deallocate_inode): Call the ext2 library routine
3626 ext2_inode_has_valid_blocks() instead of
3627 inode_has_valid_blocks().
3629 * swapfs.c (swap_inodes): Add check so that we don't try to call
3630 swap_inode_blocks unless the inode has valid blocks.
3631 (Otherwise a long fast symlink might cause
3632 swap_inode_blocks to erroneously get called.)
3634 Wed Jan 22 14:42:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3636 * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
3637 PR_2_DOT_DOT_NULL_TERM.
3639 * pass2.c (check_dot, check_dot_dot): Make sure the new . and
3640 .. entries are null-terminated, since the 2.0 kernel
3641 requires this (for no good reason).
3643 Mon Jan 20 20:05:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3645 * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
3646 that we can recover from missing inode tables.
3648 * dirinfo.c (get_dir_info): If there are no directories in the
3649 dir_info abstraction, don't core dump (because dir_info is
3652 * e2fsck.c (main): Don't try using the backup superblocks if there
3654 (check_super_block): If there are illegal inode table or
3655 bitmaps, set the filesystem as being in error.
3657 Wed Jan 15 11:32:01 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
3659 * pass2.c (check_dir_block): Added check to make sure that rec_len
3660 is a a multiple of 4 (so that the directory entries are
3663 Sat Dec 28 12:16:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3665 * Makefile.in (uninstall): Uninstall all programs in the PROGS
3667 (PROGS): Don't build and install the extend program by
3671 Sat Dec 7 16:41:02 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3673 * pass1.c (process_inodes): Make sure the stashed_ino variable is
3674 saved and restored as well.
3675 (pass1): For fast sym links, skip the check_blocks
3676 processing step altogether.
3678 Mon Dec 2 09:28:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3680 * problem.c, message.c: New files, to completely refurbish how
3681 filesystem problems are reported to the user. The
3682 diagnostic messages are now encoded out in an easily
3683 customizable, extensible format. The messages printed out
3684 in preen mode are all on one line, and contain the device
3687 Fri Nov 29 20:26:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3689 * swapfs.c (swap_inodes): When swapping a filesystem, ignore
3692 * pass1.c (pass1): Ignore missing inode table errors during the
3693 scan, and just skip past those inodes.
3695 * pass3.c (check_root): Remove root_ino argument, and assume that
3696 the root inode must be EXT2_ROOT_INO. Move responsibility
3697 of setting the parent of the root inode in the directory
3698 inode structure to pass2().
3700 * pass2.c (check_dir_block): Don't allow links to the root
3703 * dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
3704 since the inode is no longer used.
3706 Tue Oct 15 00:06:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3708 * e2fsck.c (main): If the superblock magic number is wrong, or the
3709 block group fails a sanity check, then automatically
3710 restart trying to use the backup superblocks.
3712 * pass1.c (mark_table_blocks): Make the inode tables ahead of
3713 everything else; in the case where a bitmap block overlays
3714 the inode table, the inode table should take precedence.
3716 * pass2.c (maybe_clear_entry): Make the deleted/unused error
3717 message fit on one line, since the error can happen during
3718 a preen pass. (We eventually need to revamp the whole
3719 e2fsck error reporting and prompting system, but that's a
3720 job for another day.)
3722 Mon Oct 14 22:29:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3724 * e2fsck.c (main): Read in the list badblocks into fs->badblocks
3725 for the benefit of the inode scan functions.
3727 * pass1.c (pass1): If ext2fs_get_next_inode() returns an error
3728 indicating that an inode is in a bad block, mark that
3729 inode as being used, as well as in the inode "bb" map.
3731 * pass2.c (maybe_clear_entry): New function which generalizes the
3732 error cases when a directory entry needs to be cleared.
3733 (check_dir_block): If an inode is in the "bb" map, offer
3734 to clear the directory entry, since the inode is in a bad
3737 * pass4.c (pass4): If an inode is marked as used, but is is marked
3738 in the "bb" map, don't process it as a disconnected inode.
3740 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3742 * Release of E2fsprogs version 1.06
3744 Mon Oct 7 00:45:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3746 * e2fsck.c (main): Print out the version number of the shared
3747 library when using the -V option.
3749 * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
3752 * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
3753 out the backup superblocks when we know we have a valid
3756 Tue Oct 1 22:00:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3758 * util.c (preenhalt): Make it explicit on preenhalt that running
3759 e2fsck manually means without the -a or -p flag.
3761 Fri Sep 27 14:41:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3763 * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
3764 (Linux/FT actually sets the mode bits, so we have to
3765 handle it specially.)
3767 * e2fsck.c (check_if_skip): Print a message if the filesystem is
3768 just dirty, so that the user knows that it's about to be
3769 checked (since this will take a while).
3771 Mon Sep 16 17:00:01 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3773 * pass4.c: If a disconnected inode is zero-length, prompt to
3774 delete it instead of connecting it to lost+found.
3776 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3778 * Release of E2fsprogs version 1.05
3780 Fri Aug 30 20:24:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3782 * pass4.c (pass4): If the user refuses to connect an unattached
3783 inode to lost+found, don't try to set i_links_count. This
3784 is bad, since if the user says yes, the inode will be
3785 marked as unused, which is not necessarily the right
3786 thing, especially since the rest of the cleanup doesn't
3789 * pass2.c (deallocate_inode): Set inode_link_info[ino] when
3790 dellocating an inode. (Not strictly necessary, but...)
3792 * pass4.c (pass4): Add "bonehead" explanation to the "programming
3795 Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3797 * e2fsck.c (PRS,main): Added new options -s and -S. -s will
3798 byte-swap the filesystem so that it is normalized. -S
3799 will byte-swap the filesystem regardless of its current
3802 * swapfs.c: New file, which will byte-swap a filesystem.
3804 Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3806 * pass1.c (pass1): Change handling on files with non-zero dtime
3807 and non-zero i_link_count; before we treated them as
3808 deleted file per botched ext2 0.3c kernel behavior. We
3809 now clear dtime instead.
3811 Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3813 * e2fsck.c (main): If e2fsck sets the clean bit, even if
3814 nothing else is changed, make sure FSCK_NONDESTRUCT is
3815 set (since after all having the filesystem set to
3816 invalid is an error. :-)
3818 Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3820 * pass1.c (process_block): Make sure that meta data doesn't get
3821 accidentally set in the dir_blocks array (which could
3822 happen in some error condtions).
3825 * pass2.c (process_bad_inode): Check for fragments in a
3826 OS-independent fashion.
3828 Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3830 * e2fsck.c (check_if_skip): Close the filesystem when skipping the
3831 cleanup for the filesystem.
3833 Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3835 * e2fsck.c: Improve corrupt_msg, so that it's less confusing.
3837 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3839 * Release of E2fsprogs version 1.04
3841 Wed May 15 21:41:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
3843 * e2fsck.c (relocate_hint): Issue a hint that the user may wish to
3844 try "e2fsck -b 8193" before allowing e2fsck to relocate
3847 * Makefile.in (e2fsck): Build e2fsck statically or dynamically
3848 depending on the option to configure. Added targets for
3849 e2fsck.static and e2fsck.shared for people who want to
3850 build a static or shared variant manually.
3852 Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
3854 * Release of E2fsprogs version 1.03
3856 Tue Mar 26 12:03:42 1996 <tytso@rsts-11.mit.edu>
3858 * e2fsck.c (show_stats): Don't use floating point to display
3859 percentage of non-contiguous files, as different libc
3860 handle result truncation differently, and this causes the
3861 test suite to bomb out depending on which libc you are
3864 * util.c (allocate_memory): Fix error message to omit extraneous
3867 Tue Mar 5 03:50:40 1996 <tytso@rsts-11.mit.edu>
3870 * pass2.c (check_dir_block):
3871 * pass1.c (pass1): Add support for dynamic first inode revision.
3873 Wed Feb 14 16:27:30 1996 <tytso@rsts-11.mit.edu>
3875 * pass3.c (check_root): Fix spelling typo
3877 Mon Feb 5 22:30:30 1996 <tytso@rsts-11.mit.edu>
3879 * e2fsck.c (check_super_block): If the superblock fails certain
3880 internal consistency checks, exit with a fatal error after
3881 printing the "superblock is corrupt message".
3883 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
3885 * Release of E2fsprogs version 1.02
3887 Wed Dec 15 21:24:26 1996 <tytso@rsts-11.mit.edu>
3889 * pass1.c (process_block): Check to see if a file is "fragmented".
3890 i.e., non-contiguous. Note that any file which is larger
3891 than the block group is guaranteed to be non-contiguous.
3892 We may want to use a different hueristic for deciding
3893 whether or not a file is "fragmented".
3895 * e2fsck.c (show_stats): Print statistics of how many
3896 non-contiguous files are on the system.
3898 Fri Dec 15 19:19:47 1995 <tytso@rsts-11.mit.edu>
3900 * badblocks.c (read_bad_blocks_file, test_disk): Fold
3901 functionality of test_disk() (which runs badblocks) into
3902 read_bad_blocks_file(); test_disk() now calls
3903 read_bad_blocks_file() with a NULL bad_blocks_file
3906 Mon Nov 20 18:30:10 1995 <tytso@rsts-11.mit.edu>
3908 * e2fsck.c (check_mount): Use #if defined(__linux__) instead of
3909 #if defined(linux). The latter won't work if we're
3912 Mon Oct 30 20:31:17 1995 <tytso@rsts-11.mit.edu>
3914 * e2fsck.c (check_mount): For Linux systems, the check to see if
3915 the root is mounted read-only has to be done for all
3916 filesystems, not just for the root filesystem, due to the
3917 way that some /etc/rc scripts are set up.
3919 Thu Oct 26 12:05:30 1995 <tytso@rsts-11.mit.edu>
3921 * Makefile.in (install): Strip programs when they are installed.
3922 (e2fsck): Build e2fsck statically.
3924 Wed Oct 25 21:18:16 1995 <tytso@rsts-11.mit.edu>
3926 * util.c (preenhalt): Preenhalt now takes an argument, which is an
3927 ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
3928 flag in the superblock in cases where preenhalt is called.
3929 All calls to preenhalt() were changed to either
3930 preenhalt(fs) or preenhalt(NULL) in a few cases where the
3931 fs pointer was not available. (Most notable, for block
3934 Mon Sep 4 21:41:03 1995 Remy Card <card@bbj>
3937 util.c: Include <sys/time.h> before <sys/resource.h>. BSD needs it.
3939 Mon Sep 4 10:14:49 1995 <tytso@rsts-11.mit.edu>
3941 * e2fsck.c (show_stats): Show statistics about how many inodes
3942 have indirect, doubly indirect, and triply indirect
3943 blocks. Allow up to 8 digits for statistics, instead of
3944 merely 6, so things look pretty for large filesystems.
3946 * pass1.c (pass1): Keep statistics about indirect, doubly
3947 indirect, and triply indirect blocks.
3949 * pass1.c (unwind_pass1): Clear the above statistics when unwinding
3952 Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o <tytso@dcl>
3954 * util.c, ehandler.c: Move #include of <sys/resource.h> after
3955 #include of "e2fsck.h", since sys/resource.h may depend on
3956 sys/time.h, which is #included in e2fsck.h.
3958 Thu Aug 17 22:33:37 1995 <tytso@rsts-11.mit.edu>
3960 * e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted()
3961 function to determine if the device is mounted.
3963 * e2fsck.c (main): Add better error messages if ext2fs_open()
3966 Wed Aug 16 16:25:02 1995 <tytso@rsts-11.mit.edu>
3968 * pass1.c (check_blocks): If we're clearing a directory, clear
3969 pb.is_dir so we don't do the following check of making
3970 sure the directory size matches; this is pointless, since
3971 we've already cleared the inode.
3973 Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3975 * pass1.c (bad_primary_block): New function, called by
3976 process_bad_block, which explains the facts of life to the
3977 user when a block in the primary superblock or primary
3978 group descriptors is bad.
3980 * pass2.c (check_dot): Handle the case where the first directory
3981 entry is used, but not ".".
3983 * pass2.c (check_dotdot): Handle the case where the second directory
3984 entry is used, but is not "..".
3986 Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
3988 * e2fsck.c (check_super_block): Get the size of the physical
3989 device and if it is smaller than the reported size of the
3990 filesystem, report an error.
3992 Sat Aug 12 03:39:18 1995 Remy Card <card@bbj>
3994 * e2fsck.c (check_if_skip): Print the number of allocated files and
3995 blocks on clean filesystems.
3997 Fri Aug 11 14:15:36 1995 Remy Card <card@bbj>
3999 * e2fsck.8: Updated date and version number.
4001 Thu Aug 10 14:26:01 1995 Remy Card <card@bbj>
4003 * pass1.c (check_blocks): Check that directory size matches *exactly*
4004 the count of allocated blocks.
4006 Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o <tytso@dcl>
4008 * pass1b.c (pass1d): Free the shared[] array when we're done with
4009 it to avoid a memory leak.
4011 * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
4014 * pass2.c (process_bad_inode): When clearing the inode, make sure
4015 the pathname is freed, to prevent a memory leak.
4017 * pass5.c (check_inode_bitmaps): Free free_array and dir_array
4018 when we're finished with them.
4019 (check_block_bitmaps): Free free_array when we're finished
4022 * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
4023 linking the executable.
4025 * pass2.c (process_bad_inode): Even on OS's that don't support the
4026 fragment fields, make sure the Linux equivalent fields are
4027 set to zero. If an OS wants to reuse these fields, which
4028 is probably a bad idea (although we may get desperate in
4029 the future) this code will have to be changed.
4031 * pass1.c (dir_block_cmp): If the block numbers are equal, compare
4032 on the inode field, and then blockcnt field. This is just
4033 to keep the ordering of dir_blocks the same on all
4034 platforms when there are more than on missing directory
4035 blocks, which are indicated directories with holes, which
4036 are indicated with the block number being set to zero.
4038 Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
4040 * pass1.c (check_blocks, process_block): check_blocks() modified
4041 to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
4042 the inode is a directory. process_block() now checks to
4043 see if a directory has a "hole", or missing block. If so,
4044 this fact is recorded in the directory block list so that
4045 the problem can be resolved in pass #2.
4047 * pass2.c (allocate_dir_block): Added allocate_dir_block() to
4048 allocate new blocks for directories with "holes". Called
4049 out of check_dir_block if a block in the directory block
4052 * pass3.c (get_lost_and_found): Move location of free(block) to
4053 prevent possible memory leak.
4055 Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
4057 * pass2.c (check_dir_block): Use a automatic, fixed-saize array
4058 instead of alloca() --- alloca is not portable! Check to
4059 make sure the filename is not longer than EXT2_NAME_LEN,
4060 and offer to fix it by truncating it, since it should
4063 * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
4064 not portable!! In any case putenv() in some systems must
4065 take a static character array or malloc()'ed memory;
4066 passing memory allocated using alloca() to putenv() is not
4069 * pass2.c (check_dot, check_dotdot): Use malloc() instead of
4070 alloca() --- alloca() is not portable!!!
4072 Tue Jul 18 20:04:02 1995 <tytso@rsx-11.mit.edu>
4074 * pass1b.c (pass1c):
4075 * pass3.c (check_root, get_lost_and_found):
4076 * pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block
4077 to read/write the directory block.
4079 Mon Jul 17 04:00:56 1995 <tytso@rsx-11.mit.edu>
4081 * util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to
4082 make sure VMIN and VTIME are set correct.
4084 Fri Jul 14 19:26:29 1995 <tytso@rsx-11.mit.edu>
4086 * pass1.c (mark_block_used): Change to be an inline function.
4087 Assume that the block validity checks are already done,
4088 and use the fast variant of the bitmap functions.
4090 Thu Jul 13 08:10:55 1995 <tytso@rsx-11.mit.edu>
4092 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
4093 bounds of the bitmaps in advance, and then use the fast
4094 variant of e2fs_test_{block,inode}_bitmap.
4096 * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
4097 the bounds checking has already been done earlier.
4099 Wed Jul 12 02:22:46 1995 <tytso@rsx-11.mit.edu>
4101 * pass1.c (pass1): Allocate and free the block_illegal_map, which
4102 is used for shortcut processing in process_block.
4103 (mark_table_blocks): Initialize block_illegal_map with the
4105 (describe_illegal_block): New helper function that
4106 describes why a block is illegal.
4107 (process_block): Use block_illegal_map as a shortcut
4108 to determine whether a block is bad. Use
4109 describe_illegal_block to print out why the block is illegal.
4111 Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl)
4113 * flushb.c: Don't include <linux/fs.h> if it doesn't exist.
4115 * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
4116 <mntent.h> if they don't exist. (Mostly so that "make
4119 * pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
4122 * e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
4125 Mon Jun 12 08:37:49 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
4127 * pass2.c (process_bad_inode, check_for_zero_long,
4128 check_for_zero_char): Change long to u32, and char to u8.
4130 Sun Jun 11 15:05:57 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
4132 * util.c (inode_has_valid_blocks):
4133 * pass2.c (process_bad_inode):
4134 * pass1.c (pass1, check_blocks, pass1_check_directory): Use
4135 LINUX_S_IS* instead of S_IS*.
4137 * e2fsck.h: Don't #include <sys/stat.h>
4139 * flushb.c (main): Add #ifdef BLKFLSBUF around ioctl. (Although
4140 this program is pretty much useless if BLKFLSBUF isn't
4143 * e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
4146 Thu Jun 8 12:31:19 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
4148 * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
4149 to allocate space for file names instead of using fixed size buffers.
4150 (process_bad_inode): Only check inode frag fields if
4151 HAVE_EXT2_FRAGS is defined (by configure).
4152 * pass1.c (pass1): Only check the inode frag fields if
4153 HAVE_EXT2_FRAGS is defined (by configure).
4155 * e2fsck.c (check_mount): Only check for a mounted filesystem if
4156 HAVE_MNTENT_H is defined (by configure).
4157 (PRS): Use alloca to allocate the new path string, instead of
4158 having a fixed size buffer (which was the wrong size anyway).
4159 (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
4162 * e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
4163 defined (by configure).
4165 * Makefile.in: Rewritten to conform to GNU coding standards and
4166 support separate compilation directories.
4168 Thu Apr 6 15:04:36 1995 Remy Card <card@bbj.ibp.fr>
4170 * pass1.c (pass1): Test the mode in reserved inodes (must be zero).
4172 Sat Mar 11 13:12:16 1995 Theodore Y. Ts'o <tytso@localhost>
4174 * pass1.c (unwind_pass1): Clear the file type statistics counter
4175 when pass 1 needs to be restarted from scratch.
4177 * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
4178 being reallocated to blocks in the next block group,
4179 instead of the current block grup.
4181 * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
4182 inode.i_links_count is set.
4184 Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11)
4186 * pass1.c (process_block): Add checks for if the block is
4187 trepassing on a superblock or group descriptor table.
4189 Sat Dec 31 00:52:11 1994 <tytso@rsx-11.mit.edu>
4191 * main.c (corrupt_msg): Extend the message which is printed out
4192 when the superblock is corrupt, to include the suggestion
4193 of using the -b option to specify an alternate superblock.
4195 Thu Nov 24 09:29:58 1994 Theodore Y. Ts'o (tytso@rt-11)
4197 * badblocks.c (read_bad_blocks_file): If we are adding or
4198 replacing bad blocks in the bad blocks inode, sanity check
4199 the bad block inode first, and clear out any illegal blocks.
4201 * pass2.c (check_name): Don't bomb out if the attempt to get the
4202 pathname of the containing directory returns an error; the
4203 directory may be too badly damaged to expect that
4204 ext2fs_get_pathname will always succeed. Use "???" if the
4205 pathname can't be obtained (it's only for a printf to the
4208 The name of the containing directory and the bad filename
4209 were incorrectly interchanged in the user message. Fixed.
4211 * pass2.c (check_name, check_dir_block): Use a common static
4212 string for the unknown pathname.
4214 Mon Nov 7 22:30:54 1994 Remy Card <card@bbj>
4216 * Fixed lots of printf formats to make sure that block and inode
4217 numbers are printed as unsigned integers.
4219 Mon Oct 24 14:10:46 1994 (tytso@rsx-11)
4221 * pass5.c (check_block_end): Fix calculation of how the last block
4222 in the block bitmap should be calculated.
4224 Wed Sep 7 10:01:13 1994 (tytso@rsx-11)
4226 * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to
4227 be an ext2fs_inode_bitmap, and free it properly.
4230 * e2fsck.c (main): Folded in Remy Card's changes to add a revision
4231 level to the superblock.
4233 Wed Aug 17 22:00:20 1994 Remy Card (card@bbj)
4235 * e2fsck.c (usage): Fixed bogus usage message.
4237 Wed Aug 17 11:21:45 1994 Theodore Y. Ts'o (tytso@rt-11)
4239 * pass1.c (process_bad_block): Fixed bug so that blocks in the
4240 backup superblocks and group descriptors are handled gracefully.
