1 2000-12-09 <tytso@snap.thunk.org>
3 * jfs_e2fsck.h, jfs_user.h: Replaces jfs_compat.h. The jfs.h file
4 has been moved to the include/linux directory.
6 * journal.c, revoke.c, recovery.c: Updated files from Stephen to
7 support the V2 superblock and revoke processing. The
8 journal.c and revoke.c files are copies from the ext3
11 * Makefile.in: Added revoke.c to the list of source/object files.
13 2000-11-16 Theodore Ts'o <tytso@valinux.com>
15 * pass1b.c: Change routines to use PR_1B_BLOCK_ITERATE when
16 reporting problems rather than using com_err directly.
18 * problem.c, problem.h (PR_1B_BLOCK_ITERATE): Add new problem code.
20 * message.c (expand_percent_expression): Add safety check. If
21 ctx->str is NULL, print "NULL" instead of dereferencing
24 * pass1b.c, pass2.c, pass3.c: Change calls to ext2fs_block_iterate
25 to ext2fs_block_iterate2, to support 64-bit filesizes and
26 to speed things up slightly by avoiding the use of the
27 ext2fs_block_iterate's compatibility shim layer.
29 2000-10-30 <tytso@snap.thunk.org>
31 * util.c (get_backup_sb): Calculate backup superblock correctly
32 when the blocksize is > 1k.
34 2000-10-26 <tytso@snap.thunk.org>
36 * jfs.h, jfs_compat.h, journal.c: Updated to include the
37 definition of the new journal superblock format; still
38 only supports V1 superblocks for now. (From sct)
40 2000-10-24 <tytso@snap.thunk.org>
42 * super.c (release_inode_block, release_inode_blocks,
43 release_orphan_inodes): Add code to deal with truncating
44 inodes which are still in use (but which are on the orphan
45 list because they need truncation).
47 * problem.c, problem.h: Rename PR_0_CLEAR_ORPHAN_INODE to
48 PR_0_ORPHAN_CLEAR_INODE, and remove
49 PR_0_ORPHAN_INODE_INUSE.
51 * journal.c (e2fsck_run_ext3_journal): Add i18n support, and print
52 a message when the journal is being recovered.
54 * pass1.c (e2fsck_pass1): Don't check the i_mode field for the
55 journal inode, if it is in use.
57 2000-09-12 <tytso@valinux.com>
60 * flushb.c: Add include of nls-enable.h which is necessary so that
61 they can compile correctly.
63 2000-08-22 <tytso@valinux.com>
65 * unix.c (main): If we're doing a read-only check, skip the
66 journal playback, but don't abort the e2fsck run.
68 * super.c (release_orphan_inodes): Fix typo; should do bounds
69 checking on next_ino instead of ino.
71 * jfs_compat.h (J_ASSERT):
72 * journal.c (e2fsck_run_ext3_journal):
73 * pass3.c (adjust_inode_count): Use fatal_error() instead of exit().
75 * unix.c: Use fatal_error() instead of exit() whenever possible.
76 Also fix the fsck exit codes so that we use FSCK_USAGE
77 when it is appropriate. Rename global_signal_ctx to
78 e2fsck_global_ctx and let it be exported globally.
80 * util.c (fatal_error): Try to flush the I/O manager before
83 2000-08-20 <tytso@valinux.com>
85 * journal.c (e2fsck_journal_load): Fix **nasty** bug which caused
86 e2fsck_check_ext3_journal to smash the journal because
87 journal->j_transaction_sequence wasn't getting
90 * journal.c: (recover_ext3_journal, e2fsck_run_ext3_journal): Move
91 call to e2fsck_clear_recover from recover_ext3_journal to
92 after the filesystem has been closed and reopened.
93 Otherwise, the superblock in the filesystem handle will
94 probably be stale, and will overwrite the newer version of
95 the superblock written by the log recovery.
97 * message.c (expand_inode_expression): Add support for %Iu and %Ig
99 * problem.h (PR_0_CLEAR_ORPHAN_INODE): Add new problem code.
101 * super.c (release_orphan_inodes, release_inode_block,
102 release_inode_blocks): Update the block group descriptor
103 counts when freeing the orphan inode. Use
104 PR_0_CLEAR_ORPHAN_INODE to report when we clear an orphan.
106 * journal.c (e2fsck_run_ext3_journal): Fix a bug where we
107 attempted to reopen the filesystem using the device name
108 instead of the filesystem name.
110 2000-08-18 <tytso@valinux.com>
112 * Makefile.in: Update the make dependencies
114 * problem.c, problem.h: Add the problem codes:
115 PR_0_ORPHAN_ILLEGAL_BLOCK_NUM,
116 PR_0_ORPHAN_ALREADY_CLEARED_BLOCK,
117 PR_0_ORPHAN_ILLEGAL_HEAD_INODE,
118 PR_0_ORPHAN_ILLEGAL_INODE, PR_0_ORPHAN_INODE_INUSE
120 * super.c (release_inode_blocks, release_orphan_inodes,
121 check_super_block): Add support for clearing orphaned
122 inodes from the unmounted filesystem.
124 * journal.c (e2fsck_recover_ext3_journal): Remove the last orphan
125 check; this is now handled in check_super_block ---
126 non-journaled filesystems can use the orphan list in the
127 future. Also, move the the re-opening of the filesystem
128 to e2fsck_run_ext3_journal().
130 2000-07-12 Andreas Dilger <adilger@turbolinux.com>
132 * journal.c: implement loading of ext3 journal for recovery code
134 * problem.c (fix_problem): return answer from PR_AFTER_CODE to caller.
135 Add journal problems.
137 * recovery.c (journal_recover): user-space ext3 journal recovery code
139 * unix.c (main) : check journal and do recovery in separate steps
141 2000-08-07 <tytso@snap.thunk.org>
143 * unix.c (calc_percent): Make sure that we don't take a floating
144 exception if the max value is zero. (should normally
145 never happen, but...)
147 2000-07-13 <tytso@valinux.com>
149 * Release of E2fsprogs 1.19
151 2000-07-06 Theodore Ts'o <tytso@valinux.com>
153 * unix.c (check_if_skip): Modify algorithm for checking
154 s_max_mnt_count to match with the kernel. (If
155 s_max_mnt_count is negative, ignore the mnt_count check.)
157 * unix.c (e2fsck_update_progress): Adjust the width of the
158 progress bar dynamically, based on the filesystem name
159 that we need to display.
161 * unix.c (main): If the ext3 needs_recovery flag is set, call
162 e2fsck_run_ext3_journal() and then restart the e2fsck run.
164 * journal.c (e2fsck_run_ext3_journal): New file which contains
165 logic to recover the ext3 journal. This version relies on
166 the kernel being able to mount the filesystem in order to
169 2000-07-05 Theodore Ts'o <tytso@valinux.com>
171 * unix.c (e2fsck_update_progress): Only save and check the last
172 percentage after multiplying it by 10, nor 1000, since we
173 only need to save values to a tenth of a percent (and the
174 percentage is already from 0 .. 100%, not 0 .. 1).
175 Also, re-arrange the logic so that we do the time
176 check only after doing the percentage check, and we
177 only advance the spinner if we're about to display it.
179 2000-07-04 Theodore Ts'o <tytso@valinux.com>
181 * pass1.c (e2fsck_pass1): Check to see if the ext3 s_last_orphan
182 field is set; if so, clear it, so that ext3 mounting code
183 won't get confused by the fact that we've cleared out the
186 2000-06-10 Theodore Ts'o <tytso@valinux.com>
188 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Add error
189 checking for a "should never happen case".
191 * problem.c, problem.h (PR_5_COPY_IBITMAP_ERROR,
192 PR_5_COPY_BBITMAP_ERROR): Add new error codes.
194 2000-05-27 Theodore Ts'o <tytso@valinux.com>
196 * pass1.c (pass1, check_size): Apply patch from Chris Wedgewood
197 (cw@foof.org) which checks to see if special devices have
198 a non-zero size, and deals with it.
200 * problem.c, problem.h (PR1_SET_NONZSIZE): Add new problem code.
202 2000-05-18 Theodore Ts'o <tytso@valinux.com>
204 * Makefile.in (install): Create a symbolic link for fsck.ext3 as
207 2000-05-08 Theodore Ts'o <tytso@valinux.com>
209 * problem.c, problem.h (PR_0_HURD_CLEAR_FILETYPE): Add new problem
212 * super.c (check_super_block): If the OS type in the superblock is
213 the Hurd, check to see if the filetype feature is set, and
214 offer to clear it if so. This needs to be done since the
215 Hurd doesn't properly support the filetype feature.
216 (And since the hurd allows the transmogrification of files
217 to special files and vice versa --- for no good reason
218 that I can understand --- it can't support the filetype
219 feature for the forseeable future, either.)
221 2000-04-03 Theodore Ts'o <tytso@valinux.com>
223 * unix.c: For platforms that don't define optarg.h, manually
224 define optarg and optind.
226 2000-03-20 Theodore Ts'o <tytso@valinux.com>
228 * pass1.c (check_immutable, e2fsck_pass1_check_device_inode):
229 Check for the append-only as well as the immutable flag.
231 * problem.c (PR_1_SET_IMMUTABLE): Adjust message to include
232 append-only flag. Fix comment for compression flag.
234 2000-02-12 <tytso@snap.thunk.org>
236 * unix.c (e2fsck_update_progress): Limit the number of updates to
237 the progress bars to 8 times a second. This allows a 9600
238 baud console link to keep up.
240 2000-02-11 <tytso@snap.thunk.org>
242 * unix.c (main): If compression is enabled on the filesystem,
243 print a warning message (for now).
245 * message.c: Add new compression shortcut: @c == compress
247 * problem.c, problem.h (PR_1_COMPR_SET): Add new error code.
249 * pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag
250 set, check to see if the filesystem supports compression.
251 If it does pass this information down to process_block()
252 so it can treat the compressed block flag words
253 correctly. If not, offer to clear the flag, since it
255 (process_block): If an inode has the compressed inode flag
256 set, allow EXT2FS_COMPRESSED_BLKADDR.
258 * pass1b.c (process_pass1b_block, delete_file_block,
260 * pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to
261 see if the block can be skipped.
263 2000-02-08 <tytso@snap.thunk.org>
265 * util.c: Make resource tracking message more concise.
268 * pass1.c (mark_table_blocks, e2fsck_pass1): Remove
269 ctx->block_illegal_map, since it's not needed by pass1,
270 and pass1b has been modified to calculate it manually if
271 needed. This reduces the memory footprint needed by e2fsck.
273 * pass1b.c (check_if_fs_block): New static function which returns
274 whether or not a block overlaps with filesystem metadata.
275 This replaces consulting the block_illegal_map bitmap.
277 * Makefile.in: Call sync after finishing building all in this
280 * unix.c (PRS): sync the filesystem before trying to use
281 BLKFLSBUF, to minimize the chance of causing dirty blocks
284 * e2fsck.h: Manually define BLKFLSBUF if not defined, and we're on
287 * pass3.c (check_directory): Only do the loop detection algorithm
288 if we've searched over 2048 parent directories and haven't
289 found the end yet. This means that in the common case, we
290 don't allocate or clear the inode_loop_detection bitmap,
291 which for large systems, merely clearing the bitmap for
292 each directory was turning out to be quite expensive.
293 Thanks to Jani Jaakkola (jjaakkol@cs.helsinki.fi) for
294 identifying this problem.
296 2000-02-06 Theodore Ts'o <tytso@valinux.com>
298 * badblocks.c, e2fsck.h, ehandler.c, emptydir.c, extend.c,
299 flushb.c, iscan.c, message.c, pass1.c, pass1b.c, pass3.c
300 pass4.c, pass5.c, problem.c, scantest.c, swapfs.c,
301 unix.c, util.c: Add Internationalization support as
302 suggested by Marco d'Itri <md@linux.it>.
304 2000-02-02 Theodore Ts'o <tytso@valinux.com>
306 * e2fsck.h, flushb.c, scantest.c: Remove uneeded include of
309 2000-01-18 Theodore Ts'o <tytso@valinux.com>
311 * Makefile.in: Since LIBUUID can sometimes include "-lsocket"
312 we need a separate DEPLIBUUID that can be used in
313 Makefile's dependency rules.
315 1999-11-23 <tytso@valinux.com>
317 * e2fsck.8.in: Update language about where to find a backup
320 1999-11-19 <tytso@valinux.com>
322 * pass1.c (process_inodes): Add shortcut handling; if
323 process_inodes_count is zero, return right away, to avoid
324 calling qsort with a non-positive count.
326 * message.c (safe_print): Fix to properly display ^A, ^B, etc. and
327 to print Delete as ^?
329 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
330 the source directory.
332 1999-11-10 <tytso@valinux.com>
334 * Release of E2fsprogs 1.18
336 1999-11-10 <tytso@valinux.com>
338 * problem.c (fix_problem): Support a new flag, PR_PREEN_NO which
339 means the answer is assumed to be no in preen mode. This
340 is now used in the PR_1_SET_IMMUTABLE code, so that in
341 preen mode we ignore these inodes and just print a warning
344 1999-11-09 <tytso@valinux.com>
346 * pass1.c (e2fsck_pass1): If the filesystem does not support
347 imagic inodes, if an inode has the imagic flag set, offer
348 to clear the imagic flag. If a valid device/fifo/socket
349 has the immutable flag set, call the new helper function
350 check_immutable() to offerto clear the immutable flag.
352 * pass2.c (check_filetype): Use the new ext2_file_type() helper
353 function instead of calculating the file_type information
356 * pass3.c (e2fsck_reconnect_file): When adding a link to
357 lost+found, calculate the filetype information so that
358 ext2fs_link() can use the information if applicable.
359 (get_lost_and_found): Create the /lost+found directory
360 with the correct filetype information if applicable.
362 * util.c (ext2_file_type), e2fsck.h: New function which returns
363 the directory entry file type information given the
366 * problem.c, problem.h: Added new problem codes PR_1_SET_IMAGIC
367 and PR_1_SET_IMMUTABLE.
369 1999-11-07 <tytso@valinux.com>
371 * pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it,
372 to prevent it from getting freed twice.
374 1999-11-06 <tytso@valinux.com>
376 * unix.c (main): Close the filesystem before freeing the context,
377 so that in the event of a free()-related segmentation
378 violation, the filesystem is properly closed and written
381 1999-10-27 <tytso@valinux.com>
383 * e2fsck.c (e2fsck_reset_context): When freeing
384 ctx->inode_reg_map, we weren't zero'ing
385 ctx->inode_reg_map, which could cause a segfault later on
388 1999-10-26 <tytso@valinux.com>
390 * problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
391 matches the standard convention).
393 1999-10-26 <tytso@valinux.com>
395 * Release of E2fsprogs 1.17
397 1999-10-26 <tytso@valinux.com>
399 * message.c (safe_print): Make safe_print take an char instead of
400 an unsigned char to fix gcc warnings.
402 1999-10-25 <tytso@valinux.com>
404 * util.c: For NT portability, don't redefine getchar(), since
405 stdio defines that. Instead we introduce a new
406 abstract macro read_a_char() which is #defined to the
407 right function as necessary.
409 * problem.c, problem.h (PR_2_NULL_NAME): Add new problem code.
411 * pass2.c (check_dir_block): Require that the length of the
412 directory entry be at least 12 bytes. Check to see if the
413 filename is zero-length, and flag that as an error.
415 1999-10-22 <tytso@valinux.com>
417 * Release of E2fsprogs 1.16
419 1999-10-22 <tytso@valinux.com>
421 * pass2.c (check_filetype): If the filetype filesystem feature is
422 not set, and a directory entry has a dirent feature, offer
423 to clear it (since 2.0 kernels will do complain will
424 interpret it as a very large name length field).
426 * problem.c (PR_2_CLEAR_FILETYPE): Add new problem code.
428 1999-10-21 <tytso@valinux.com>
430 * e2fsck.8.in: Update man page to use a more standard format (bold
431 option flags and italicized variables), as suggested by
432 Andreas Dilger (adilger@enel.ucalgary.ca)
434 * pass4.c (e2fsck_pass4): If an inode is set in the
435 inode_imagic_map bitmap, don't check to see if it is
436 disconnected from the inode tree (because it almost
437 certainly will be). Free inode_imagic_map at the end of
440 * pass2.c (check_dir_block, check_filetype): If the FILETYPE
441 feature is set, check the directory entry's filetype
442 information field, and fix/set it if necessary.
443 (e2fsck_pass2): Free the inode_reg_map bitmap at the end
446 * pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
447 information for inode_reg_map and inode_imagic_map, which
448 indicates which inodes are regular files and AFS inodes,
450 Since only the master superblock is written during a
451 restart, force that superblock to be used after a restart;
452 otherwise changes to the block group descriptors end up
455 * problem.c, problemP.h: If e2fsck is run -n, make def_yn variable
456 be 0 for "no". Add support for a new flag, PR_NO_NOMSG,
457 which supresses the problem message if e2fsck is run with
460 * problem.c, problem.h (PR_2_SET_FILETYPE, PR_2_BAD_FILETYPE): Add
463 * message.c (expand_dirent_expression): Add support for %dt which
464 prints the dirent type information.
466 * e2fsck.c (e2fsck_reset_context): Free new bitmaps (inode_reg_map
467 and inode_imagic_map).
469 * e2fsck.h (e2fsck_t): Add new inode_reg_map and inode_magic_map
470 to the context structure.
472 1999-09-24 <tytso@valinux.com>
474 * unix.c (PRS), util.c (ask_yn): Add #ifdef's to make
475 e2fsprogs easier to port to non-Unix platforms.
477 1999-09-07 <tytso@valinux.com>
479 * pass3.c (adjust_inode_count): Fix bug where we didn't keep the
480 internal and external inode counts in sync when we
481 decremented an inode whose link count was already zero.
482 Now we skip incrementing or decrementing both link counts
483 if we would cause an overflow condition.
484 (expand_dir, expand_dir_proc): Change where we update the
485 inode block count and size files so that the block count
486 field is updated correctly when we create an indirect block.
488 1999-08-05 <tytso@valinux.com>
490 * super.c (check_super_block): Check to see whether the
491 inodes_per_group value in the superblock is insanely too
494 1999-08-02 <tytso@valinux.com>
496 * pass1b.c (clone_file_block): Don't clear the dup_map flag if
497 the block also shares data with the fs metadata when
498 the count drops to 1, since the block should still be
499 cloned, as fs metadata isn't included in the count.
501 1999-07-18 Theodore Ts'o <tytso@valinux.com>
503 * Release of E2fsprogs 1.15
505 1999-07-19 <tytso@valinux.com>
507 * unix.c (usage): Add minimalist emergency help to the usage
510 1999-07-18 <tytso@valinux.com>
512 * unix.c: Add support for calculating a progress bar if the -C0
513 option is given. The function e2fsck_clear_progbar()
514 clears the progress bar and must be called before any
515 message is issued. SIGUSR1 will enable the progress bar,
516 and SIGUSR2 will disable the progress bar. This is used
517 by fsck to handle parallel filesystem checks. Also, set
518 the device_name from the filesystem label if it is
521 * e2fsck.h: Add new flags E2F_FLAG_PROG_BAR and
522 E2F_FLAG_PROG_SUPRESS. Add new field in the e2fsck
523 structure which contains the last tenth of a percent
524 printed for the user.
526 * message.c (print_e2fsck_message): Add call to
527 e2fsck_clear_progbar().
529 * pass1.c (e2fsck_pass1):
530 * pass2.c (e2fsck_pass2):
531 * pass3.c (e2fsck_pass3):
532 * pass4.c (e2fsck_pass4):
533 * pass5.c (e2fsck_pass5): Add call to e2fsck_clear_progbar when
534 printing the resource tracking information.
536 * pass5.c (check_block_bitmaps, check_inode_bitmaps): If there is
537 an error in the bitmaps, suppress printing the progress
538 bar using the suppression flag for the remainder of the
539 check, in order to clean up the display.
541 1999-06-30 <tytso@valinux.com>
543 * unix.c (check_mount): Clean up the abort message displayed when
544 the filesystem is mounted and either stdout or stdin isn't
547 1999-06-25 <tytso@valinux.com>
550 * pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
551 pass1_check_directory, e2fsck_use_inode_shortcuts): Make
552 pass1_* be private static functions, and create new
553 function e2fsck_use_inode_shortcuts which sets and clears
554 the inode shortcut functions in the fs structure.
557 * pass2.c (e2fsck_process_bad_inode): Make process_bad_inode() an
560 * pass4.c (e2fsck_pass4): Call e2fsck_process_bad_inode to check
561 if a disconnected inode has any problems before
562 connecting it to /lost+found. Bug and suggested fix by
563 Pavel Machek <pavel@bug.ucw.cz>
565 1999-06-21 <tytso@valinux.com>
567 * unix.c (main): Add missing space in the disk write-protected
570 1999-05-22 <tytso@rsts-11.mit.edu>
572 * problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem
575 * super.c (check_super_block): Add check to make sure the total
576 number of inodes is sane, since this can be calculated
577 from the number of groups times the number of inodes per
578 group. Offer to correct it if it is incorrect.
580 1999-03-19 <tytso@rsts-11.mit.edu>
582 * pass5.c (check_block_end): Fix fencepost condition where when
583 clearing the block padding we were missing the last position
586 1999-05-17 <tytso@rsts-11.mit.edu>
588 * unix.c (reserve_stdio_fds): Add safety check in case
589 reserve_stdio_fds couldn't open /dev/null.
591 1999-03-14 Theodore Ts'o <tytso@rsts-11.mit.edu>
593 * util.c (print_resource_track): Use mallinfo if present to get
594 more accurate malloc statistics.
596 * pass3.c (get_lost_and_found): Check to see if lost+found is a
597 plain file; if so, offer to unlink it.
599 * problem.c, problem.h (PR_3_LPF_NOTDIR): Add new problem code.
601 1999-03-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
603 * problem.c: Fix problem message for PR_1_BAD_GROUP_DESCRIPTORS so
604 that the block group number is printed. Add new prompt,
607 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
609 * Release of E2fsprogs 1.14
611 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
613 * message.c (safe_print): New function which prints strings,
614 converting non-printable characters using the '^' and
615 M-notation. This function is now used to print directory
616 name entries and pathnames.
618 Mon Jan 4 02:28:59 1999 Theodore Y. Ts'o <tytso@mit.edu>
620 * unix.c (main): Reset the context before calling ext2fs_close(),
621 to avoid referencing already freed memory.
623 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
625 * Release of E2fsprogs 1.13
627 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
629 * Makefile.in: Updated dependencies.
631 1998-11-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
633 * pass3.c (get_lost_and_found): If the filesystem is not opened
634 read-only, then force /lost+found to be created if it is
637 * problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen
640 1998-10-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
642 * unix.c (main): Move ext2fs_close() after e2fsck_free_context()
643 since e2fsck_free_context may reference data in ctx->fs.
645 * e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL
646 before checking ctx->fs->dblist.
648 1998-10-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
650 * pass1.c (e2fsck_pass1): Use the device check subroutine on
651 FIFO's and Socket's, so that we catch bogus immutable inodes.
653 * pass2.c (process_bad_inode): Process bad socket and fifo's.
655 * problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
658 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
660 * problem.c: Add PR_3_NO_DIRINFO error code.
662 * super.c (check_super_value): Rename min and max to min_val and
663 max_val to avoid possible cpp macro conflicts.
665 * pass4.c (e2fsck_pass4): Rename max to maxgroup, to avoid
666 possible cpp macro conflicts.
668 * pass3.c (e2fsck_pass3): Rename max to maxdirs, to avoid possible
670 (check_directory): Fix logic to avoid possible core dump
671 in the case of ext2fs_get_dir_info returning NULL. (By
672 the time we get here, it should never happen, but...).
673 Also simply/streamline the control flow of the function.
675 1998-08-17 Theodore Ts'o <tytso@rsts-11.mit.edu>
677 * unix.c (check_if_skip): Move the "not cleanly mounted" check
678 ahead of the maximal mount and too long since checked tests.
679 (reserve_stdio_fds): Make sure 0,1,2 file descriptors are
680 open, so that we don't open the filesystem using the same
681 file descriptor as stdout or stderr.
683 1998-08-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
685 * pass2.c (e2fsck_pass2): Fix the progress accounting so that we
688 * pass3.c (e2fsck_pass3): Change progress accounting to be
689 consistent with the other e2fsck passes.
691 * e2fsck.c (e2fsck_run): At the end of each pass, call the
692 progress function with the pass number set to zero.
694 * unix.c (e2fsck_update_progress): If the pass number is zero,
695 ignore the call, since that indicates that we just want to
696 deallocate any progress structures.
698 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
700 * Release of E2fsprogs 1.12
702 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
704 * unix.c (main): Fix typo in checking the incompat feature set; it
705 should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.
707 1998-07-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
709 * badblocks.c (test_disk): Don't clear the existing bad blocks
710 list when using e2fsck -c, since it may cause blocks with
711 marginal errors to be dropped from the bad blocks list.
713 Mon Jul 6 10:32:11 1998 Theodre Ts'o <tytso@lurch.mit.edu>
715 * pass1.c (e2fsck_pass1): Use ext2fs_sb structure for
716 compatibility with older kernels.
718 1998-06-25 Theodore Ts'o <tytso@rsts-11.mit.edu>
720 * unix.c (e2fsck_update_progress): Remove unused variables.
722 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
724 * pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
725 collision with LFS API.
727 * pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
728 properly initialized.
729 (e2fsck_pass1): Don't allow the the boot loader inode to
730 be a directory (clear the inode mode field if so).
732 1998-05-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
734 * unix.c (PRS): Added new option -C, which causes e2fsck to print
735 progress updates so that callers can keep track of the
736 completion progress of e2fsck. Designed for use by
737 progress, except for -C 0, which prints a spinning report
738 which may be useful for some users.
740 * pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
741 scheme (useful for larger filesystems).
743 * e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
744 progress reporting functions.
746 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
748 * pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
749 appropriate return type for comparison functions for qsort.
751 * e2fsck.h: Add #ifdef protection for unistd.h
753 * super.c: Remove header files already included by e2fsck.h
755 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
757 * dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
758 size of the memory to be resized to ext2fs_resize_mem().
760 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
762 * Makefile.in: Change to use new installation directory variables
763 convention. Fix uninstall rules to take $(DESTDIR) into
764 account. Remove cat8dir from the installdirs target,
765 since modern man package don't necessarily put the cat
766 directory in /usr/man/cat?.
768 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
771 extern in e2fsck.h to prevent -Wall warnings.
773 * pass4.c (e2fsck_pass4): Remove unused variable 'j'.
775 1998-03-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
777 * super.c (check_super_block): Fix broken superblock sanity check
778 when calculating blocks_per_group if s_log_frag_size !=
779 s_log_block_size. Since we don't support fragments, this
780 isn't a bug deal, but it's good to get it fixed.
782 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
784 * unix.c: Fix bug in check of feature set, to make sure we can
785 really fix this filesystem.
787 * problem.h: Make blkcount type to be of type blkcnt_t. Make the
788 num field be a 64 bit type. Add the problem code
789 PR_1_FEATURE_LARGE_FILES
791 * problem.c: Add table entry for the problem code
792 PR_1_FEATURE_LARGE_FILES.
794 * pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
795 a problem for directory inodes. (Since it is also
796 i_size_high now.) If there are no large_files, then
797 clear the LARGE_FLAG feature flag. If there are
798 large_files, but the LARGE_FLAG feature flag is not set,
799 complain and offer to fix it.
800 (check_blocks): Add support to deal with non-directory
801 inodes that have i_size_high set (i.e., large_files).
802 Don't give an error if a directory has preallocated
803 blocks, to support the DIR_PREALLOC feature.
804 (process_block, process_bad_block): The blockcnt variable
805 is a type of blkcnt_t, for conversion to the new
808 * pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
809 a problem for directory inodes. (Since it is also
812 * message.c (expand_inode_expression): Print a 64-bits of the
813 inode size for non-directory inodes. (Directory inodes
814 can only use a 32-bit directory acl size, since
815 i_size_high is shared with i_dir_acl.) Add sanity check
816 so that trying to print out the directory acl on a
817 non-directory inode will print zero.
818 (expand_percent_expression): %B and %N, which print
819 pctx->blkcount and pctx->num, can now be 64 bit
820 variables. Print them using the "%lld" format if
821 EXT2_NO_64_TYPE is not defined.
823 * e2fsck.h: Add the large_flagsfield to the e2fsck context.
825 * e2fsck.c (e2fsck_reset_context): Clear the large_flags
828 Sun Mar 8 23:08:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
830 * pass3.c (fix_dotdot_proc):
831 * pass2.c (check_dot, check_dotdot, check_name, check_dir_block):
832 * message.c (expand_dirent_expression): Mask off the high eight
833 bits of the directory entry's name_len field, so that it
834 can be used for other purposes.
836 Fri Feb 27 00:01:39 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
838 * e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
839 include EXT2_FLAG_RESTART anymore, we need to adjust this
840 routine so that it *does* return in the case of it seeing
843 * pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
844 done callback function, which may set context abort
845 flags. So we need to test the context abort flags after
846 we call ext2_get_next_inode().
847 (process_inodes): If we abort due out of process_inodes,
848 do a clean exit by breaking out of the for loop instead of
851 * e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
852 considered a SIGNAL mask (i.e., requiring an immediate
853 abort of processing to restart). FLAG_RESTART just means
854 that we want to restart once pass 1 is complete.
856 Tue Feb 24 15:19:40 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
858 * Change the progress function to return an integer; if returns 1,
859 then the progress function is expected to have set the
860 e2fsck context flag signalling a user abort, and the
861 caller should also initiate a user abort.
863 Tue Feb 17 19:03:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
865 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
866 end_problem_latch() unless there was actually a problem
867 latched. Simplifies semantics of the latch processing.
869 Mon Feb 16 17:31:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
871 * e2fsck.h: Add new field, priv_data to the e2fsck context
872 structure. It should be used by callers of the e2fsck
873 functions only, and not by anything in e2fsck itself.
875 Mon Feb 7 17:31:04 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
877 * super.c: Instead of call ext2fs_get_device_size(), define and call
878 e2fsck_get_device_size(). (This function may be stubbed
879 out in special versions of e2fsck.)
881 * pass3.c, pass4.c: Remove extra calls to the progress function
884 * mke2fs.8.in: Update man page to note that the format of the bad
885 block file is the same as the one generated by badblocks.
887 Sun Feb 1 07:57:14 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
889 * dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
891 * e2fsck.h: Include <time.h> since it is needed
893 * super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
896 Tue Jan 20 15:37:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
898 * unix.c (main): In the case where the filesystem revision is too
899 high, print the message about the superblock possibly
902 * e2fsck.8.in: Add expanded comments about how the -b option
905 Sat Jan 17 13:02:16 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
907 * e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
908 the ext2-specific header files are in a flat directory.
910 * dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
911 super.c, swapfs.c, unix.c: Explicitly cast all assignments
912 from void * to be compatible with C++.
914 Tue Jan 6 11:30:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
916 * unix.c (sync_disk): Remove sync_disk and calls to that function,
917 since ext2fs_close() now takes care of this.
919 Mon Dec 29 14:45:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
921 * pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
922 ehandler.c, unix.c: Change use of private to be priv_data,
923 to avoid C++ reserved name clash.
925 Fri Nov 28 09:30:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
927 * dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
928 of e2fsck_get_num_dirs, which has been removed.
930 Tue Nov 25 15:54:35 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
932 * Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
933 to compile and install flushb.
935 Mon Nov 24 06:48:00 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
937 * pass1.c (e2fsck_pass1_check_device_inode): For now, only check
938 to make sure the extra i_blocks in a device are cleared if
939 the immutable flag is set.
941 * util.c (print_resource_track): Fix typo which caused the
942 time/resource tracking to print "Pass 1 :" instead of
945 Thu Nov 20 16:02:23 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
947 * pass3.c (expand_directory): Fix bug which could cause core dump
948 when expanding the directory, and the bitmaps hadn't yet
949 been read in. Also, only use ext2fs_write_dir_block when
950 writing a directory block, not when writing out a fresh
953 Wed Nov 19 16:15:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
955 * pass1.c (process_bad_block): Fix bug where first_block wasn't
956 getting incremented, which caused user to get a
957 "Programming error?" warning if there was a bad block in a
958 non-primary superblock/group_descriptor. Also fixed
959 another bug so that ext2fs_bg_has_super() is consulted, to
960 avoid problems when using a filesystem with the
961 sparse_groups option set and there are bad blocks at the
962 beginning of a group which doesn't have a superblock.
964 Thu Nov 6 16:10:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
966 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the
967 progress indicator function.
969 * pass1.c (scan_callback): Add call to the progress feedback
970 function (if it exists).
972 Tue Nov 4 09:45:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
974 * super.c (check_super_block): Skip the device size check if the
975 get_device_size returns EXT2_EXT_UNIMPLEMENTED.
977 * iscan.c (main): Don't use fatal_error() anymore.
979 * pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
980 calling fatal_error(0).
982 * problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
983 PR_3_NO_ROOT_INODE_ABORT): New problem codes.
985 * problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
987 * problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
989 * problemP.h: New file which separates out the private fix_problem
992 * util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
993 swapfs.c util.c: allocate_memory() now takes a e2fsck
994 context as its first argument, and rename it to be
995 e2fsck_allocate_memory().
997 Mon Nov 3 14:35:29 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
999 * unix.c (main): Add a special case check for the error code EROFS
1000 and display an appropriate error message for this case.
1002 * [lots of files]: Change ext2fs_read_inode, ext2fs_write_inode
1003 to take the e2fsck context as their first argument.
1004 Change dir_info.c routines to take an e2fsck_context,
1005 renamed them to start with e2fsck_ to avoid namespace
1006 issues, and changed them to store the directory
1007 information inside the e2fsck context.
1008 Added e2fsck_run() which calls all of the e2fsck passes in
1009 the correct order, and which handles the return of abort
1010 codes. Added abort processing, both via setjmp/longjmp
1011 and via flags in the e2fsck context. Use a flag in the
1012 e2fsck context instead of the restart_e2fsck global
1013 variable. Change uses of free and malloc to
1014 ext2fs_free_mem and ext2fs_get_mem.
1016 Fri Oct 31 01:12:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1018 * pass1.c, pass3.c: Rename new error codes to _ET_ in them for
1021 Sat Oct 25 00:10:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1023 * pass3.c (get_lost_and_found): Check error return of
1024 EXT2_FILE_NOT_FOUND instead of ENOTDIR
1026 * pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
1029 Fri Oct 24 00:12:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1031 * unix.c (PRS): Make the variable which getopt returns into be
1032 an int, so that it won't lose on platforms where char is
1035 * pass1b.c (clone_file): Fix bug in error reporting in the case
1036 where cs.errcode is non-zero.
1038 Sun Oct 19 21:12:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1040 * pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
1041 RESOURCE_TRACK around code which uses init_resource_track
1042 and print_resource_track. (Not all systems have timeval)
1044 * super.c: Remove excess #includes which are not necessary.
1046 * e2fsck.h: Add #ifdef's for HAVE_SYS_TYPES_H and HAVE_SYS_TIME_H
1048 Fri Oct 3 13:40:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1050 * pass*.c, super.c: Massive changes to avoid using printf and
1051 com_err routines. All diagnostic messages are now routed
1052 through the fix_problem interface.
1054 Sat Sep 6 17:13:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1056 * pass2.c (check_dir_block): Check for duplicate '.' and '..'
1059 * problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
1062 Tue Sep 2 09:04:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1064 * problem.c: Added new problem codes for some of the
1065 superblock corruption checks, and for the pass header
1066 messages. ("Pass 1: xxxxx")
1068 * util.c (print_resource_track): Now takes a description
1071 Mon Aug 25 10:23:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1073 * super.c, unix.c, e2fsck.c: New files to separate out the
1074 operating-specific operations out from e2fsck.c.
1075 e2fsck.c now contains the global e2fsck context management
1076 routines, and super.c contains the "pass 0" initial
1077 validation of the superblock and global block group
1080 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
1081 (nearly) all global variables and moved them to the e2fsck
1084 * problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
1085 PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS,
1086 PR_0_BLOCKS_PER_GROUP, PR_0_FIRST_DATA_BLOCK
1088 Thu Aug 14 10:55:21 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1090 * message.c: Add compression for the word "Illegal"
1092 * problem.c: Added entries for PR_2_BAD_CHAR_DEV and
1095 Wed Aug 13 09:55:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1097 * pass1.c (pass1, check_device_inode), pass2.c
1098 (process_bad_inode): Use a more stringent test for a valid
1101 Sun Aug 10 18:58:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1103 * e2fsck.c (check_mount): Add stronger warning message about the
1104 perils of running e2fsck on a mounted filesystem.
1106 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1108 * Release of E2fsprogs 1.11
1110 Thu Jun 12 00:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1112 * pass1.c (mark_table_blocks): Mark the superblock and group
1113 descriptor blocks first, so that any conflicts between
1114 these and the bitmap or inode table blocks is noticed.
1116 * problem.c: Fix message printed out when a block or inode bitmap
1117 conflicts with other fs data, has the correct group number
1120 Tue Jun 10 12:07:37 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1122 * pass2.c (pass2): Check the error return from ext2fs_dblist_iterate.
1124 Thu May 8 22:45:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1126 * e2fsck.8.in: Fix minor typos and grammer oops found by Bill
1127 Hawes (whawes@star.net).
1129 * badblocks.c (read_bad_blocks_file): Pass the blocksize to the
1130 bad blocks command so that all of the filesystem gets
1131 tested in the case where the blocksize 2048 or 4096.
1133 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
1135 * Release of E2fsprogs version 1.10
1137 Mon Apr 21 22:43:08 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1139 * pass1b.c (pass1b): While scanning for inodes, simply skip inodes
1140 where ext2fs_get_next_inode returns the
1141 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE error.
1143 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1145 * Release of E2fsprogs version 1.09
1147 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1149 * Release of E2fsprogs version 1.08
1151 Thu Apr 10 13:51:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1153 * pass1b.c (clone_file_block): If we clone a directory, we need to
1154 update the dblist entry so that we check (and correct) the
1155 right directory block.
1157 Sun Apr 6 09:13:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1159 * pass1.c (process_block): Don't clear blocks references to
1160 filesystem metadata; let pass 1B handle this case.
1162 * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
1164 * pass1b.c (pass1d): Deal with a block which is shared with
1165 filesystem metadata.
1167 * e2fsck.h: Make block_illegal_map be a global variable
1169 Sat Apr 5 11:51:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1171 * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
1173 (get_backup_sb): New function which attempts to obtain the
1174 correct backup superblock (if possible).
1176 Fri Apr 4 10:46:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1178 * e2fsck.c (main): Check the version of the library, and warn if
1179 the library is out of date; this happens generally due to
1180 users who manually install e2fsprogs.
1182 * pass1.c (pass1_get_blocks): If the passed in inode number for
1183 get_blocks isn't what we're expecting pass back
1184 EXT2_ET_CALLBACK_NOT_HANDLED.
1186 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
1188 * Release of E2fsprogs version 1.07
1190 Tue Mar 11 10:31:47 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1192 * icount.c: New file which implements an inode count abstraction.
1193 This significantly reduces amount of memory needed to
1194 check really large filesystems.
1196 * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
1199 Fri Mar 7 08:28:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1201 * dirinfo.c (dir_info_iter): New function which allows iteration
1202 over the directories in the dir_info map.
1204 * pass3.c (pass3, check_directory): Speed up pass 3 by iterating
1205 over all directories in the dir_info structure, instead of
1206 iterating all inodes looking for directories, and then
1207 looking up the directories using get_dir_info().
1209 Sat Feb 1 11:33:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1211 * pass1.c (pass1, process_block):
1212 * pass2.c (pass2): Use the ext2_dblist abstraction instead of
1213 manual code to manage the directory block list information.
1215 * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
1216 (deallocate_inode): Call the ext2 library routine
1217 ext2_inode_has_valid_blocks() instead of
1218 inode_has_valid_blocks().
1220 * swapfs.c (swap_inodes): Add check so that we don't try to call
1221 swap_inode_blocks unless the inode has valid blocks.
1222 (Otherwise a long fast symlink might cause
1223 swap_inode_blocks to erroneously get called.)
1225 Wed Jan 22 14:42:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1227 * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
1228 PR_2_DOT_DOT_NULL_TERM.
1230 * pass2.c (check_dot, check_dot_dot): Make sure the new . and
1231 .. entries are null-terminated, since the 2.0 kernel
1232 requires this (for no good reason).
1234 Mon Jan 20 20:05:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1236 * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
1237 that we can recover from missing inode tables.
1239 * dirinfo.c (get_dir_info): If there are no directories in the
1240 dir_info abstraction, don't core dump (because dir_info is
1243 * e2fsck.c (main): Don't try using the backup superblocks if there
1245 (check_super_block): If there are illegal inode table or
1246 bitmaps, set the filesystem as being in error.
1248 Wed Jan 15 11:32:01 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1250 * pass2.c (check_dir_block): Added check to make sure that rec_len
1251 is a a multiple of 4 (so that the directory entries are
1254 Sat Dec 28 12:16:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1256 * Makefile.in (uninstall): Uninstall all programs in the PROGS
1258 (PROGS): Don't build and install the extend program by
1262 Sat Dec 7 16:41:02 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1264 * pass1.c (process_inodes): Make sure the stashed_ino variable is
1265 saved and restored as well.
1266 (pass1): For fast sym links, skip the check_blocks
1267 processing step altogether.
1269 Mon Dec 2 09:28:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1271 * problem.c, message.c: New files, to completely refurbish how
1272 filesystem problems are reported to the user. The
1273 diagnostic messages are now encoded out in an easily
1274 customizable, extensible format. The messages printed out
1275 in preen mode are all on one line, and contain the device
1278 Fri Nov 29 20:26:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1280 * swapfs.c (swap_inodes): When swapping a filesystem, ignore
1283 * pass1.c (pass1): Ignore missing inode table errors during the
1284 scan, and just skip past those inodes.
1286 * pass3.c (check_root): Remove root_ino argument, and assume that
1287 the root inode must be EXT2_ROOT_INO. Move responsibility
1288 of setting the parent of the root inode in the directory
1289 inode structure to pass2().
1291 * pass2.c (check_dir_block): Don't allow links to the root
1294 * dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
1295 since the inode is no longer used.
1297 Tue Oct 15 00:06:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1299 * e2fsck.c (main): If the superblock magic number is wrong, or the
1300 block group fails a sanity check, then automatically
1301 restart trying to use the backup superblocks.
1303 * pass1.c (mark_table_blocks): Make the inode tables ahead of
1304 everything else; in the case where a bitmap block overlays
1305 the inode table, the inode table should take precedence.
1307 * pass2.c (maybe_clear_entry): Make the deleted/unused error
1308 message fit on one line, since the error can happen during
1309 a preen pass. (We eventually need to revamp the whole
1310 e2fsck error reporting and prompting system, but that's a
1311 job for another day.)
1313 Mon Oct 14 22:29:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1315 * e2fsck.c (main): Read in the list badblocks into fs->badblocks
1316 for the benefit of the inode scan functions.
1318 * pass1.c (pass1): If ext2fs_get_next_inode() returns an error
1319 indicating that an inode is in a bad block, mark that
1320 inode as being used, as well as in the inode "bb" map.
1322 * pass2.c (maybe_clear_entry): New function which generalizes the
1323 error cases when a directory entry needs to be cleared.
1324 (check_dir_block): If an inode is in the "bb" map, offer
1325 to clear the directory entry, since the inode is in a bad
1328 * pass4.c (pass4): If an inode is marked as used, but is is marked
1329 in the "bb" map, don't process it as a disconnected inode.
1331 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1333 * Release of E2fsprogs version 1.06
1335 Mon Oct 7 00:45:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1337 * e2fsck.c (main): Print out the version number of the shared
1338 library when using the -V option.
1340 * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
1343 * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
1344 out the backup superblocks when we know we have a valid
1347 Tue Oct 1 22:00:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1349 * util.c (preenhalt): Make it explicit on preenhalt that running
1350 e2fsck manually means without the -a or -p flag.
1352 Fri Sep 27 14:41:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1354 * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
1355 (Linux/FT actually sets the mode bits, so we have to
1356 handle it specially.)
1358 * e2fsck.c (check_if_skip): Print a message if the filesystem is
1359 just dirty, so that the user knows that it's about to be
1360 checked (since this will take a while).
1362 Mon Sep 16 17:00:01 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1364 * pass4.c: If a disconnected inode is zero-length, prompt to
1365 delete it instead of connecting it to lost+found.
1367 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1369 * Release of E2fsprogs version 1.05
1371 Fri Aug 30 20:24:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1373 * pass4.c (pass4): If the user refuses to connect an unattached
1374 inode to lost+found, don't try to set i_links_count. This
1375 is bad, since if the user says yes, the inode will be
1376 marked as unused, which is not necessarily the right
1377 thing, especially since the rest of the cleanup doesn't
1380 * pass2.c (deallocate_inode): Set inode_link_info[ino] when
1381 dellocating an inode. (Not strictly necessary, but...)
1383 * pass4.c (pass4): Add "bonehead" explanation to the "programming
1386 Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1388 * e2fsck.c (PRS,main): Added new options -s and -S. -s will
1389 byte-swap the filesystem so that it is normalized. -S
1390 will byte-swap the filesystem regardless of its current
1393 * swapfs.c: New file, which will byte-swap a filesystem.
1395 Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1397 * pass1.c (pass1): Change handling on files with non-zero dtime
1398 and non-zero i_link_count; before we treated them as
1399 deleted file per botched ext2 0.3c kernel behavior. We
1400 now clear dtime instead.
1402 Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1404 * e2fsck.c (main): If e2fsck sets the clean bit, even if
1405 nothing else is changed, make sure FSCK_NONDESTRUCT is
1406 set (since after all having the filesystem set to
1407 invalid is an error. :-)
1409 Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1411 * pass1.c (process_block): Make sure that meta data doesn't get
1412 accidentally set in the dir_blocks array (which could
1413 happen in some error condtions).
1416 * pass2.c (process_bad_inode): Check for fragments in a
1417 OS-independent fashion.
1419 Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1421 * e2fsck.c (check_if_skip): Close the filesystem when skipping the
1422 cleanup for the filesystem.
1424 Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1426 * e2fsck.c: Improve corrupt_msg, so that it's less confusing.
1428 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1430 * Release of E2fsprogs version 1.04
1432 Wed May 15 21:41:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1434 * e2fsck.c (relocate_hint): Issue a hint that the user may wish to
1435 try "e2fsck -b 8193" before allowing e2fsck to relocate
1438 * Makefile.in (e2fsck): Build e2fsck statically or dynamically
1439 depending on the option to configure. Added targets for
1440 e2fsck.static and e2fsck.shared for people who want to
1441 build a static or shared variant manually.
1443 Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
1445 * Release of E2fsprogs version 1.03
1447 Tue Mar 26 12:03:42 1996 <tytso@rsts-11.mit.edu>
1449 * e2fsck.c (show_stats): Don't use floating point to display
1450 percentage of non-contiguous files, as different libc
1451 handle result truncation differently, and this causes the
1452 test suite to bomb out depending on which libc you are
1455 * util.c (allocate_memory): Fix error message to omit extraneous
1458 Tue Mar 5 03:50:40 1996 <tytso@rsts-11.mit.edu>
1461 * pass2.c (check_dir_block):
1462 * pass1.c (pass1): Add support for dynamic first inode revision.
1464 Wed Feb 14 16:27:30 1996 <tytso@rsts-11.mit.edu>
1466 * pass3.c (check_root): Fix spelling typo
1468 Mon Feb 5 22:30:30 1996 <tytso@rsts-11.mit.edu>
1470 * e2fsck.c (check_super_block): If the superblock fails certain
1471 internal consistency checks, exit with a fatal error after
1472 printing the "superblock is corrupt message".
1474 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1476 * Release of E2fsprogs version 1.02
1478 Wed Dec 15 21:24:26 1996 <tytso@rsts-11.mit.edu>
1480 * pass1.c (process_block): Check to see if a file is "fragmented".
1481 i.e., non-contiguous. Note that any file which is larger
1482 than the block group is guaranteed to be non-contiguous.
1483 We may want to use a different hueristic for deciding
1484 whether or not a file is "fragmented".
1486 * e2fsck.c (show_stats): Print statistics of how many
1487 non-contiguous files are on the system.
1489 Fri Dec 15 19:19:47 1995 <tytso@rsts-11.mit.edu>
1491 * badblocks.c (read_bad_blocks_file, test_disk): Fold
1492 functionality of test_disk() (which runs badblocks) into
1493 read_bad_blocks_file(); test_disk() now calls
1494 read_bad_blocks_file() with a NULL bad_blocks_file
1497 Mon Nov 20 18:30:10 1995 <tytso@rsts-11.mit.edu>
1499 * e2fsck.c (check_mount): Use #if defined(__linux__) instead of
1500 #if defined(linux). The latter won't work if we're
1503 Mon Oct 30 20:31:17 1995 <tytso@rsts-11.mit.edu>
1505 * e2fsck.c (check_mount): For Linux systems, the check to see if
1506 the root is mounted read-only has to be done for all
1507 filesystems, not just for the root filesystem, due to the
1508 way that some /etc/rc scripts are set up.
1510 Thu Oct 26 12:05:30 1995 <tytso@rsts-11.mit.edu>
1512 * Makefile.in (install): Strip programs when they are installed.
1513 (e2fsck): Build e2fsck statically.
1515 Wed Oct 25 21:18:16 1995 <tytso@rsts-11.mit.edu>
1517 * util.c (preenhalt): Preenhalt now takes an argument, which is an
1518 ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
1519 flag in the superblock in cases where preenhalt is called.
1520 All calls to preenhalt() were changed to either
1521 preenhalt(fs) or preenhalt(NULL) in a few cases where the
1522 fs pointer was not available. (Most notable, for block
1525 Mon Sep 4 21:41:03 1995 Remy Card <card@bbj>
1528 util.c: Include <sys/time.h> before <sys/resource.h>. BSD needs it.
1530 Mon Sep 4 10:14:49 1995 <tytso@rsts-11.mit.edu>
1532 * e2fsck.c (show_stats): Show statistics about how many inodes
1533 have indirect, doubly indirect, and triply indirect
1534 blocks. Allow up to 8 digits for statistics, instead of
1535 merely 6, so things look pretty for large filesystems.
1537 * pass1.c (pass1): Keep statistics about indirect, doubly
1538 indirect, and triply indirect blocks.
1540 * pass1.c (unwind_pass1): Clear the above statistics when unwinding
1543 Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o <tytso@dcl>
1545 * util.c, ehandler.c: Move #include of <sys/resource.h> after
1546 #include of "e2fsck.h", since sys/resource.h may depend on
1547 sys/time.h, which is #included in e2fsck.h.
1549 Thu Aug 17 22:33:37 1995 <tytso@rsts-11.mit.edu>
1551 * e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted()
1552 function to determine if the device is mounted.
1554 * e2fsck.c (main): Add better error messages if ext2fs_open()
1557 Wed Aug 16 16:25:02 1995 <tytso@rsts-11.mit.edu>
1559 * pass1.c (check_blocks): If we're clearing a directory, clear
1560 pb.is_dir so we don't do the following check of making
1561 sure the directory size matches; this is pointless, since
1562 we've already cleared the inode.
1564 Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1566 * pass1.c (bad_primary_block): New function, called by
1567 process_bad_block, which explains the facts of life to the
1568 user when a block in the primary superblock or primary
1569 group descriptors is bad.
1571 * pass2.c (check_dot): Handle the case where the first directory
1572 entry is used, but not ".".
1574 * pass2.c (check_dotdot): Handle the case where the second directory
1575 entry is used, but is not "..".
1577 Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1579 * e2fsck.c (check_super_block): Get the size of the physical
1580 device and if it is smaller than the reported size of the
1581 filesystem, report an error.
1583 Sat Aug 12 03:39:18 1995 Remy Card <card@bbj>
1585 * e2fsck.c (check_if_skip): Print the number of allocated files and
1586 blocks on clean filesystems.
1588 Fri Aug 11 14:15:36 1995 Remy Card <card@bbj>
1590 * e2fsck.8: Updated date and version number.
1592 Thu Aug 10 14:26:01 1995 Remy Card <card@bbj>
1594 * pass1.c (check_blocks): Check that directory size matches *exactly*
1595 the count of allocated blocks.
1597 Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o <tytso@dcl>
1599 * pass1b.c (pass1d): Free the shared[] array when we're done with
1600 it to avoid a memory leak.
1602 * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
1605 * pass2.c (process_bad_inode): When clearing the inode, make sure
1606 the pathname is freed, to prevent a memory leak.
1608 * pass5.c (check_inode_bitmaps): Free free_array and dir_array
1609 when we're finished with them.
1610 (check_block_bitmaps): Free free_array when we're finished
1613 * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
1614 linking the executable.
1616 * pass2.c (process_bad_inode): Even on OS's that don't support the
1617 fragment fields, make sure the Linux equivalent fields are
1618 set to zero. If an OS wants to reuse these fields, which
1619 is probably a bad idea (although we may get desperate in
1620 the future) this code will have to be changed.
1622 * pass1.c (dir_block_cmp): If the block numbers are equal, compare
1623 on the inode field, and then blockcnt field. This is just
1624 to keep the ordering of dir_blocks the same on all
1625 platforms when there are more than on missing directory
1626 blocks, which are indicated directories with holes, which
1627 are indicated with the block number being set to zero.
1629 Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1631 * pass1.c (check_blocks, process_block): check_blocks() modified
1632 to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
1633 the inode is a directory. process_block() now checks to
1634 see if a directory has a "hole", or missing block. If so,
1635 this fact is recorded in the directory block list so that
1636 the problem can be resolved in pass #2.
1638 * pass2.c (allocate_dir_block): Added allocate_dir_block() to
1639 allocate new blocks for directories with "holes". Called
1640 out of check_dir_block if a block in the directory block
1643 * pass3.c (get_lost_and_found): Move location of free(block) to
1644 prevent possible memory leak.
1646 Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1648 * pass2.c (check_dir_block): Use a automatic, fixed-saize array
1649 instead of alloca() --- alloca is not portable! Check to
1650 make sure the filename is not longer than EXT2_NAME_LEN,
1651 and offer to fix it by truncating it, since it should
1654 * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
1655 not portable!! In any case putenv() in some systems must
1656 take a static character array or malloc()'ed memory;
1657 passing memory allocated using alloca() to putenv() is not
1660 * pass2.c (check_dot, check_dotdot): Use malloc() instead of
1661 alloca() --- alloca() is not portable!!!

1677 * pass1.c (mark_block_used): Change to be an inline function.
1678 Assume that the block validity checks are already done,
1679 and use the fast variant of the bitmap functions.
1681 Thu Jul 13 08:10:55 1995 <tytso@rsx-11.mit.edu>
1683 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
1684 bounds of the bitmaps in advance, and then use the fast
1685 variant of e2fs_test_{block,inode}_bitmap.
1687 * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
1688 the bounds checking has already been done earlier.
1690 Wed Jul 12 02:22:46 1995 <tytso@rsx-11.mit.edu>
1692 * pass1.c (pass1): Allocate and free the block_illegal_map, which
1693 is used for shortcut processing in process_block.

1696 (describe_illegal_block): New helper function that
1697 describes why a block is illegal.
1698 (process_block): Use block_illegal_map as a shortcut
1699 to determine whether a block is bad. Use
1700 describe_illegal_block to print out why the block is illegal.
1702 Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl)
1704 * flushb.c: Don't include <linux/fs.h> if it doesn't exist.
1706 * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
1707 <mntent.h> if they don't exist. (Mostly so that "make

1724 * pass2.c (process_bad_inode):
1725 * pass1.c (pass1, check_blocks, pass1_check_directory): Use
1726 LINUX_S_IS* instead of S_IS*.
1728 * e2fsck.h: Don't #include <sys/stat.h>

1731 this program is pretty much useless if BLKFLSBUF isn't
1734 * e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
1737 Thu Jun 8 12:31:19 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1739 * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
1740 to allocate space for file names instead of using fixed size buffers.
1741 (process_bad_inode): Only check inode frag fields if
1742 HAVE_EXT2_FRAGS is defined (by configure).
1743 * pass1.c (pass1): Only check the inode frag fields if
1744 HAVE_EXT2_FRAGS is defined (by configure).
1746 * e2fsck.c (check_mount): Only check for a mounted filesystem if
1747 HAVE_MNTENT_H is defined (by configure).
1748 (PRS): Use alloca to allocate the new path string, instead of
1749 having a fixed size buffer (which was the wrong size anyway).
1750 (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
1753 * e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
1754 defined (by configure).
1756 * Makefile.in: Rewritten to conform to GNU coding standards and
1757 support separate compilation directories.
1759 Thu Apr 6 15:04:36 1995 Remy Card <card@bbj.ibp.fr>
1761 * pass1.c (pass1): Test the mode in reserved inodes (must be zero).

1766 when pass 1 needs to be restarted from scratch.
1768 * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
1769 being reallocated to blocks in the next block group,
1770 instead of the current block grup.
1772 * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
1773 inode.i_links_count is set.
1775 Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11)
1777 * pass1.c (process_block): Add checks for if the block is
1778 trepassing on a superblock or group descriptor table.
1780 Sat Dec 31 00:52:11 1994 <tytso@rsx-11.mit.edu>
1782 * main.c (corrupt_msg): Extend the message which is printed out
1783 when the superblock is corrupt, to include the suggestion
1784 of using the -b option to specify an alternate superblock.

1788 * badblocks.c (read_bad_blocks_file): If we are adding or
1789 replacing bad blocks in the bad blocks inode, sanity check
1790 the bad block inode first, and clear out any illegal blocks.
1792 * pass2.c (check_name): Don't bomb out if the attempt to get the
1793 pathname of the containing directory returns an error; the
1794 directory may be too badly damaged to expect that
1795 ext2fs_get_pathname will always succeed. Use "???" if the
1796 pathname can't be obtained (it's only for a printf to the
1799 The name of the containing directory and the bad filename
1800 were incorrectly interchanged in the user message. Fixed.

1803 string for the unknown pathname.
1805 Mon Nov 7 22:30:54 1994 Remy Card <card@bbj>

1808 numbers are printed as unsigned integers.
1810 Mon Oct 24 14:10:46 1994 (tytso@rsx-11)
1812 * pass5.c (check_block_end): Fix calculation of how the last block
1813 in the block bitmap should be calculated.
1815 Wed Sep 7 10:01:13 1994 (tytso@rsx-11)
1817 * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to

1821 * e2fsck.c (main): Folded in Remy Card's changes to add a revision
1822 level to the superblock.
1824 Wed Aug 17 22:00:20 1994 Remy Card (card@bbj)
