3 * badblocks.c, e2fsck.h, ehandler.c, emptydir.c, extend.c,
4 flushb.c, iscan.c, message.c, pass1.c, pass1b.c, pass3.c
5 pass4.c, pass5.c, problem.c, scantest.c, swapfs.c,
6 unix.c, util.c: Add Internationalization support as
7 suggested by Marco d'Itri <md@linux.it>.

10
11 * e2fsck.h, flushb.c, scantest.c: Remove uneeded include of
12 linux/fs.h
13
Theodore Ts'o894edb22000-01-18 21:27:12 +0000142000-01-18 Theodore Ts'o <tytso@valinux.com>
15
16 * Makefile.in: Since LIBUUID can sometimes include "-lsocket"
17 we need a separate DEPLIBUUID that can be used in
18 Makefile's dependency rules.
19
Theodore Ts'oa1ccadb1999-11-23 13:57:16 +0000201999-11-23 <tytso@valinux.com>
21
22 * e2fsck.8.in: Update language about where to find a backup
23 superblock.
24
Theodore Ts'o5c36a2f1999-11-19 18:42:30 +0000251999-11-19 <tytso@valinux.com>
26
Theodore Ts'o86a63e91999-11-23 13:52:48 +000027 * pass1.c (process_inodes): Add shortcut handling; if
28 process_inodes_count is zero, return right away, to avoid
29 calling qsort with a non-positive count.
30
Theodore Ts'oec8d2c31999-11-19 18:52:36 +000031 * message.c (safe_print): Fix to properly display ^A, ^B, etc. and
32 to print Delete as ^?
33
Theodore Ts'o5c36a2f1999-11-19 18:42:30 +000034 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
35 the source directory.
36
Theodore Ts'oa846d2f1999-11-10 15:50:24 +0000371999-11-10 <tytso@valinux.com>
38
Theodore Ts'ocd086361999-11-10 16:00:39 +000039 * Release of E2fsprogs 1.18
40
411999-11-10 <tytso@valinux.com>
42
Theodore Ts'oa846d2f1999-11-10 15:50:24 +000043 * problem.c (fix_problem): Support a new flag, PR_PREEN_NO which
44 means the answer is assumed to be no in preen mode. This
45 is now used in the PR_1_SET_IMMUTABLE code, so that in
46 preen mode we ignore these inodes and just print a warning
47 message.
48
Theodore Ts'o6fdc7a31999-11-10 13:34:40 +0000491999-11-09 <tytso@valinux.com>
50
51 * pass1.c (e2fsck_pass1): If the filesystem does not support
52 imagic inodes, if an inode has the imagic flag set, offer
53 to clear the imagic flag. If a valid device/fifo/socket
54 has the immutable flag set, call the new helper function
55 check_immutable() to offerto clear the immutable flag.
56
57 * pass2.c (check_filetype): Use the new ext2_file_type() helper
58 function instead of calculating the file_type information
59 manually.
60
61 * pass3.c (e2fsck_reconnect_file): When adding a link to
62 lost+found, calculate the filetype information so that
63 ext2fs_link() can use the information if applicable.
64 (get_lost_and_found): Create the /lost+found directory
65 with the correct filetype information if applicable.
66
67 * util.c (ext2_file_type), e2fsck.h: New function which returns
68 the directory entry file type information given the
69 inode's mode bits.
70
71 * problem.c, problem.h: Added new problem codes PR_1_SET_IMAGIC
72 and PR_1_SET_IMMUTABLE.
73
Theodore Ts'o7142db01999-11-08 18:46:54 +0000741999-11-07 <tytso@valinux.com>
75
76 * pass4.c (e2fsck_pass4): Clear inode_imagic_map after freeing it,
77 to prevent it from getting freed twice.
78
791999-11-06 <tytso@valinux.com>
80
81 * unix.c (main): Close the filesystem before freeing the context,
82 so that in the event of a free()-related segmentation
83 violation, the filesystem is properly closed and written
84 out.
85
861999-10-27 <tytso@valinux.com>
87
88 * e2fsck.c (e2fsck_reset_context): When freeing
89 ctx->inode_reg_map, we weren't zero'ing
90 ctx->inode_reg_map, which could cause a segfault later on
91 in the e2fsck run.
92
931999-10-26 <tytso@valinux.com>
94
95 * problem.h (PR_2_SPLIT_DOT): Fix excess zero in problem code (now
96 matches the standard convention).
97
Theodore Ts'of68aa411999-10-26 14:20:22 +0000981999-10-26 <tytso@valinux.com>
99
Theodore Ts'o28e11941999-10-26 18:17:20 +0000100 * Release of E2fsprogs 1.17
101
1021999-10-26 <tytso@valinux.com>
103
Theodore Ts'of68aa411999-10-26 14:20:22 +0000104 * message.c (safe_print): Make safe_print take an char instead of
105 an unsigned char to fix gcc warnings.
106
Theodore Ts'oc40db6d1999-10-25 21:03:34 +00001071999-10-25 <tytso@valinux.com>
108
Theodore Ts'oe6597041999-10-26 02:30:16 +0000109 * util.c: For NT portability, don't redefine getchar(), since
110 stdio defines that. Instead we introduce a new
111 abstract macro read_a_char() which is #defined to the
112 right function as necessary.
113
Theodore Ts'oc40db6d1999-10-25 21:03:34 +0000114 * problem.c, problem.h (PR_2_NULL_NAME): Add new problem code.
115
116 * pass2.c (check_dir_block): Require that the length of the
117 directory entry be at least 12 bytes. Check to see if the
118 filename is zero-length, and flag that as an error.
119
Theodore Ts'o7847c1d1999-10-22 15:11:42 +00001201999-10-22 <tytso@valinux.com>
121
Theodore Ts'o614fdfd1999-10-23 03:19:51 +0000122 * Release of E2fsprogs 1.16
123
1241999-10-22 <tytso@valinux.com>
125
Theodore Ts'o7847c1d1999-10-22 15:11:42 +0000126 * pass2.c (check_filetype): If the filetype filesystem feature is
127 not set, and a directory entry has a dirent feature, offer
128 to clear it (since 2.0 kernels will do complain will
129 interpret it as a very large name length field).
130
131 * problem.c (PR_2_CLEAR_FILETYPE): Add new problem code.
132
Theodore Ts'oaa4115a1999-10-21 19:33:18 +00001331999-10-21 <tytso@valinux.com>
134
Theodore Ts'ocaf8ce41999-10-21 19:56:34 +0000135 * e2fsck.8.in: Update man page to use a more standard format (bold
136 option flags and italicized variables), as suggested by
137 Andreas Dilger (adilger@enel.ucalgary.ca)
138
Theodore Ts'oaa4115a1999-10-21 19:33:18 +0000139 * pass4.c (e2fsck_pass4): If an inode is set in the
140 inode_imagic_map bitmap, don't check to see if it is
141 disconnected from the inode tree (because it almost
142 certainly will be). Free inode_imagic_map at the end of
143 pass 4.
144
145 * pass2.c (check_dir_block, check_filetype): If the FILETYPE
146 feature is set, check the directory entry's filetype
147 information field, and fix/set it if necessary.
148 (e2fsck_pass2): Free the inode_reg_map bitmap at the end
149 of pass 2.
150
151 * pass1.c (e2fsck_pass1, alloc_imagic_map): Allocate and fill in
152 information for inode_reg_map and inode_imagic_map, which
153 indicates which inodes are regular files and AFS inodes,
154 respectively.
155 Since only the master superblock is written during a
156 restart, force that superblock to be used after a restart;
157 otherwise changes to the block group descriptors end up
158 getting ignored.
159
160 * problem.c, problemP.h: If e2fsck is run -n, make def_yn variable
161 be 0 for "no". Add support for a new flag, PR_NO_NOMSG,
162 which supresses the problem message if e2fsck is run with
163 the -n option.
164
165 * problem.c, problem.h (PR_2_SET_FILETYPE, PR_2_BAD_FILETYPE): Add
166 new problem codes.
167
168 * message.c (expand_dirent_expression): Add support for %dt which
169 prints the dirent type information.
170
171 * e2fsck.c (e2fsck_reset_context): Free new bitmaps (inode_reg_map
172 and inode_imagic_map).
173
174 * e2fsck.h (e2fsck_t): Add new inode_reg_map and inode_magic_map
175 to the context structure.
176
Theodore Ts'o9ecd8be1999-10-20 18:24:31 +00001771999-09-24 <tytso@valinux.com>
178
179 * unix.c (PRS), util.c (ask_yn): Add #ifdef's to make
180 e2fsprogs easier to port to non-Unix platforms.
181
1821999-09-07 <tytso@valinux.com>
Theodore Ts'oc1faf9c1999-09-14 20:00:54 +0000183
184 * pass3.c (adjust_inode_count): Fix bug where we didn't keep the
185 internal and external inode counts in sync when we
186 decremented an inode whose link count was already zero.
187 Now we skip incrementing or decrementing both link counts
188 if we would cause an overflow condition.
189 (expand_dir, expand_dir_proc): Change where we update the
190 inode block count and size files so that the block count
191 field is updated correctly when we create an indirect block.
192
Theodore Ts'o78cf0541999-10-20 18:29:18 +00001931999-08-05 <tytso@valinux.com>
194
195 * super.c (check_super_block): Check to see whether the
196 inodes_per_group value in the superblock is insanely too
197 high.
198
Theodore Ts'oc1faf9c1999-09-14 20:00:54 +00001991999-08-02 <tytso@valinux.com>
200
201 * pass1b.c (clone_file_block): Don't clear the dup_map flag if
202 the block also shares data with the fs metadata when
203 the count drops to 1, since the block should still be
204 cloned, as fs metadata isn't included in the count.
205
2061999-07-18 Theodore Ts'o <tytso@valinux.com>
Theodore Ts'o657cb971999-07-30 23:19:10 +0000207
208 * Release of E2fsprogs 1.15
209
Theodore Ts'ob55199e1999-07-19 15:37:46 +00002101999-07-19 <tytso@valinux.com>
211
212 * unix.c (usage): Add minimalist emergency help to the usage
213 message.
214
Theodore Ts'o5596def1999-07-19 15:27:37 +00002151999-07-18 <tytso@valinux.com>
216
217 * unix.c: Add support for calculating a progress bar if the -C0
218 option is given. The function e2fsck_clear_progbar()
219 clears the progress bar and must be called before any
220 message is issued. SIGUSR1 will enable the progress bar,
221 and SIGUSR2 will disable the progress bar. This is used
222 by fsck to handle parallel filesystem checks. Also, set
223 the device_name from the filesystem label if it is
224 available.
225
226 * e2fsck.h: Add new flags E2F_FLAG_PROG_BAR and
227 E2F_FLAG_PROG_SUPRESS. Add new field in the e2fsck
228 structure which contains the last tenth of a percent
229 printed for the user.
230
231 * message.c (print_e2fsck_message): Add call to
232 e2fsck_clear_progbar().
233
234 * pass1.c (e2fsck_pass1):
235 * pass2.c (e2fsck_pass2):
236 * pass3.c (e2fsck_pass3):
237 * pass4.c (e2fsck_pass4):
238 * pass5.c (e2fsck_pass5): Add call to e2fsck_clear_progbar when
239 printing the resource tracking information.
240
241 * pass5.c (check_block_bitmaps, check_inode_bitmaps): If there is
242 an error in the bitmaps, suppress printing the progress
243 bar using the suppression flag for the remainder of the
244 check, in order to clean up the display.
245
Theodore Ts'o74033351999-07-01 03:00:47 +00002461999-06-30 <tytso@valinux.com>
247
248 * unix.c (check_mount): Clean up the abort message displayed when
249 the filesystem is mounted and either stdout or stdin isn't
250 a tty.
251
2521999-06-25 <tytso@valinux.com>
Theodore Ts'oe72a9ba1999-06-25 15:40:18 +0000253
254 * e2fsck.h:
255 * pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
256 pass1_check_directory, e2fsck_use_inode_shortcuts): Make
257 pass1_* be private static functions, and create new
258 function e2fsck_use_inode_shortcuts which sets and clears
259 the inode shortcut functions in the fs structure.
260
261 * e2fsck.h:
262 * pass2.c (e2fsck_process_bad_inode): Make process_bad_inode() an
263 exported function.
264
265 * pass4.c (e2fsck_pass4): Call e2fsck_process_bad_inode to check
266 if a disconnected inode has any problems before
267 connecting it to /lost+found. Bug and suggested fix by
268 Pavel Machek <pavel@bug.ucw.cz>
269
2701999-06-21 <tytso@valinux.com>
Theodore Ts'o813bbb21999-06-22 03:17:45 +0000271
272 * unix.c (main): Add missing space in the disk write-protected
273 message.
274
Theodore Ts'od4b0ce01999-06-18 01:09:29 +00002751999-05-22 <tytso@rsts-11.mit.edu>
276
277 * problem.c, problem.h (PR_0_INODE_COUNT_WRONG): Add new problem
278 code.
279
280 * super.c (check_super_block): Add check to make sure the total
281 number of inodes is sane, since this can be calculated
282 from the number of groups times the number of inodes per
283 group. Offer to correct it if it is incorrect.
284
Theodore Ts'oe79d1b21999-06-18 01:06:59 +00002851999-03-19 <tytso@rsts-11.mit.edu>
286
287 * pass5.c (check_block_end): Fix fencepost condition where when
288 clearing the block padding we were missing the last position
289 in the bitmap.
290
Theodore Ts'o75d83be1999-05-18 03:16:36 +00002911999-05-17 <tytso@rsts-11.mit.edu>
292
293 * unix.c (reserve_stdio_fds): Add safety check in case
294 reserve_stdio_fds couldn't open /dev/null.
295
Theodore Ts'o4a9f5931999-03-16 19:32:52 +00002961999-03-14 Theodore Ts'o <tytso@rsts-11.mit.edu>
297
298 * util.c (print_resource_track): Use mallinfo if present to get
299 more accurate malloc statistics.
300
301 * pass3.c (get_lost_and_found): Check to see if lost+found is a
Theodore Ts'oc54b3c31999-07-03 07:20:06 +0000302 plain file; if so, offer to unlink it.
Theodore Ts'o4a9f5931999-03-16 19:32:52 +0000303
304 * problem.c, problem.h (PR_3_LPF_NOTDIR): Add new problem code.
305
3061999-03-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
307
308 * problem.c: Fix problem message for PR_1_BAD_GROUP_DESCRIPTORS so
309 that the block group number is printed. Add new prompt,
310 PROMPT_UNLINK.
311
3121999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
313
314 * Release of E2fsprogs 1.14
315
Theodore Ts'o9e51eca1999-01-09 16:32:31 +00003161999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
317
318 * message.c (safe_print): New function which prints strings,
319 converting non-printable characters using the '^' and
320 M-notation. This function is now used to print directory
321 name entries and pathnames.
322
Theodore Ts'o73f17cf1999-01-04 07:35:45 +0000323Mon Jan 4 02:28:59 1999 Theodore Y. Ts'o <tytso@mit.edu>
324
325 * unix.c (main): Reset the context before calling ext2fs_close(),
326 to avoid referencing already freed memory.
327
Theodore Ts'o556ad131998-12-19 08:10:58 +00003281998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
329
330 * Release of E2fsprogs 1.13
331
Theodore Ts'o5a679c81998-12-03 16:40:38 +00003321998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
333
334 * Makefile.in: Updated dependencies.
335
3361998-11-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
337
338 * pass3.c (get_lost_and_found): If the filesystem is not opened
339 read-only, then force /lost+found to be created if it is
340 not present.
341
342 * problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen
343 operation.
344
Theodore Ts'o1dde43f1998-11-14 04:18:28 +00003451998-10-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
346
347 * unix.c (main): Move ext2fs_close() after e2fsck_free_context()
348 since e2fsck_free_context may reference data in ctx->fs.
349
350 * e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL
351 before checking ctx->fs->dblist.
352
3531998-10-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
354
355 * pass1.c (e2fsck_pass1): Use the device check subroutine on
356 FIFO's and Socket's, so that we catch bogus immutable inodes.
357
358 * pass2.c (process_bad_inode): Process bad socket and fifo's.
359
360 * problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
361 PR_2_BAD_SOCKET.
362
Theodore Ts'o7f813ba1998-09-03 01:26:03 +00003631998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
364
365 * problem.c: Add PR_3_NO_DIRINFO error code.
366
367 * super.c (check_super_value): Rename min and max to min_val and
368 max_val to avoid possible cpp macro conflicts.
369
370 * pass4.c (e2fsck_pass4): Rename max to maxgroup, to avoid
371 possible cpp macro conflicts.
372
373 * pass3.c (e2fsck_pass3): Rename max to maxdirs, to avoid possible
374 cpp macro conflicts.
375 (check_directory): Fix logic to avoid possible core dump
376 in the case of ext2fs_get_dir_info returning NULL. (By
377 the time we get here, it should never happen, but...).
378 Also simply/streamline the control flow of the function.
379
Theodore Ts'o24fc5031998-08-26 15:23:31 +00003801998-08-17 Theodore Ts'o <tytso@rsts-11.mit.edu>
381
382 * unix.c (check_if_skip): Move the "not cleanly mounted" check
383 ahead of the maximal mount and too long since checked tests.
384 (reserve_stdio_fds): Make sure 0,1,2 file descriptors are
385 open, so that we don't open the filesystem using the same
386 file descriptor as stdout or stderr.
387
Theodore Ts'of75c28d1998-08-01 04:18:06 +00003881998-08-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
389
390 * pass2.c (e2fsck_pass2): Fix the progress accounting so that we
391 get to 100%.
392
393 * pass3.c (e2fsck_pass3): Change progress accounting to be
394 consistent with the other e2fsck passes.
395
396 * e2fsck.c (e2fsck_run): At the end of each pass, call the
397 progress function with the pass number set to zero.
398
399 * unix.c (e2fsck_update_progress): If the pass number is zero,
400 ignore the call, since that indicates that we just want to

404
Theodore Ts'o4a5fa191998-07-09 05:42:45 +0000405 * Release of E2fsprogs 1.12
406
4071998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
408
Theodore Ts'o8144d671998-07-09 05:33:18 +0000409 * unix.c (main): Fix typo in checking the incompat feature set; it
410 should be checked against EXT2_LIB_FEATURE_INCOMPAT_SUPP.
411
Theodore Ts'o1fad9041998-07-07 05:44:43 +00004121998-07-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
413
414 * badblocks.c (test_disk): Don't clear the existing bad blocks
415 list when using e2fsck -c, since it may cause blocks with
416 marginal errors to be dropped from the bad blocks list.
417
Theodore Ts'o874b4d21998-07-06 14:33:12 +0000418Mon Jul 6 10:32:11 1998 Theodre Ts'o <tytso@lurch.mit.edu>
419
420 * pass1.c (e2fsck_pass1): Use ext2fs_sb structure for
421 compatibility with older kernels.
422
Theodore Ts'o818180c1998-06-27 05:11:14 +00004231998-06-25 Theodore Ts'o <tytso@rsts-11.mit.edu>
424
425 * unix.c (e2fsck_update_progress): Remove unused variables.
426
Theodore Ts'o9d1bd3d1998-06-10 20:45:22 +00004271998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
428
429 * pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
430 collision with LFS API.
431
432 * pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
433 properly initialized.
434 (e2fsck_pass1): Don't allow the the boot loader inode to
435 be a directory (clear the inode mode field if so).
436
Theodore Ts'oefac9a11998-05-07 05:02:00 +00004371998-05-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
438
439 * unix.c (PRS): Added new option -C, which causes e2fsck to print
440 progress updates so that callers can keep track of the
441 completion progress of e2fsck. Designed for use by
442 progress, except for -C 0, which prints a spinning report
443 which may be useful for some users.
444
445 * pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
446 scheme (useful for larger filesystems).
447
448 * e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
449 progress reporting functions.
450
Theodore Ts'o4c77fe51998-04-30 17:35:59 +00004511998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
452
453 * pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
454 appropriate return type for comparison functions for qsort.
455
456 * e2fsck.h: Add #ifdef protection for unistd.h
457
458 * super.c: Remove header files already included by e2fsck.h
459
Theodore Ts'o76f875d1998-04-27 01:41:13 +00004601998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
461
462 * dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
463 size of the memory to be resized to ext2fs_resize_mem().
464
Theodore Ts'o7e44f241998-04-01 03:16:29 +00004651998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
466
467 * Makefile.in: Change to use new installation directory variables
468 convention. Fix uninstall rules to take $(DESTDIR) into
469 account. Remove cat8dir from the installdirs target,
470 since modern man package don't necessarily put the cat
471 directory in /usr/man/cat?.
472
Theodore Ts'o17dba281998-03-30 01:16:26 +00004731998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
474
475 * super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
476 extern in e2fsck.h to prevent -Wall warnings.
477
478 * pass4.c (e2fsck_pass4): Remove unused variable 'j'.
479
4801998-03-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
481
482 * super.c (check_super_block): Fix broken superblock sanity check
483 when calculating blocks_per_group if s_log_frag_size !=
484 s_log_block_size. Since we don't support fragments, this
485 isn't a bug deal, but it's good to get it fixed.
486
Theodore Ts'o246501c1998-03-24 16:22:38 +00004871998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
488
489 * unix.c: Fix bug in check of feature set, to make sure we can
490 really fix this filesystem.
491
492 * problem.h: Make blkcount type to be of type blkcnt_t. Make the
493 num field be a 64 bit type. Add the problem code
494 PR_1_FEATURE_LARGE_FILES
495
496 * problem.c: Add table entry for the problem code
497 PR_1_FEATURE_LARGE_FILES.
498
499 * pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
500 a problem for directory inodes. (Since it is also
501 i_size_high now.) If there are no large_files, then
502 clear the LARGE_FLAG feature flag. If there are
503 large_files, but the LARGE_FLAG feature flag is not set,
504 complain and offer to fix it.
505 (check_blocks): Add support to deal with non-directory
506 inodes that have i_size_high set (i.e., large_files).
507 Don't give an error if a directory has preallocated
508 blocks, to support the DIR_PREALLOC feature.
509 (process_block, process_bad_block): The blockcnt variable
510 is a type of blkcnt_t, for conversion to the new
511 block_iterate2.
512
513 * pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
514 a problem for directory inodes. (Since it is also
515 i_size_high now.)
516
517 * message.c (expand_inode_expression): Print a 64-bits of the
518 inode size for non-directory inodes. (Directory inodes
519 can only use a 32-bit directory acl size, since
520 i_size_high is shared with i_dir_acl.) Add sanity check
521 so that trying to print out the directory acl on a
522 non-directory inode will print zero.
523 (expand_percent_expression): %B and %N, which print
524 pctx->blkcount and pctx->num, can now be 64 bit
525 variables. Print them using the "%lld" format if
526 EXT2_NO_64_TYPE is not defined.
527
528 * e2fsck.h: Add the large_flagsfield to the e2fsck context.
529
530 * e2fsck.c (e2fsck_reset_context): Clear the large_flags
531 field.
532
Theodore Ts'ob6f79831998-03-09 13:10:37 +0000533Sun Mar 8 23:08:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
534
535 * pass3.c (fix_dotdot_proc):
536 * pass2.c (check_dot, check_dotdot, check_name, check_dir_block):
537 * message.c (expand_dirent_expression): Mask off the high eight
538 bits of the directory entry's name_len field, so that it
539 can be used for other purposes.
540
Theodore Ts'o2df1f6a1998-02-27 05:03:48 +0000541Fri Feb 27 00:01:39 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
542
543 * e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
544 include EXT2_FLAG_RESTART anymore, we need to adjust this
545 routine so that it *does* return in the case of it seeing
546 EXT2_FLAG_RESTART.
547
548 * pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
549 done callback function, which may set context abort
550 flags. So we need to test the context abort flags after
551 we call ext2_get_next_inode().
552 (process_inodes): If we abort due out of process_inodes,
553 do a clean exit by breaking out of the for loop instead of
554 just returning.
555
556 * e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
557 considered a SIGNAL mask (i.e., requiring an immediate
558 abort of processing to restart). FLAG_RESTART just means
559 that we want to restart once pass 1 is complete.
560
Theodore Ts'oa02ce9d1998-02-24 20:22:23 +0000561Tue Feb 24 15:19:40 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
562
563 * Change the progress function to return an integer; if returns 1,
564 then the progress function is expected to have set the
565 e2fsck context flag signalling a user abort, and the
566 caller should also initiate a user abort.
567
Theodore Ts'o63c49691998-02-20 05:24:59 +0000568Tue Feb 17 19:03:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
569
570 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
571 end_problem_latch() unless there was actually a problem
572 latched. Simplifies semantics of the latch processing.
573
Theodore Ts'o43139321998-02-16 22:34:46 +0000574Mon Feb 16 17:31:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
575
576 * e2fsck.h: Add new field, priv_data to the e2fsck context
577 structure. It should be used by callers of the e2fsck
578 functions only, and not by anything in e2fsck itself.
579
580Mon Feb 7 17:31:04 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
581
582 * super.c: Instead of call ext2fs_get_device_size(), define and call
583 e2fsck_get_device_size(). (This function may be stubbed
584 out in special versions of e2fsck.)
585
586 * pass3.c, pass4.c: Remove extra calls to the progress function
587 that weren't needed.
588
589 * mke2fs.8.in: Update man page to note that the format of the bad
590 block file is the same as the one generated by badblocks.
591
Theodore Ts'o54be2cc1998-02-01 12:58:48 +0000592Sun Feb 1 07:57:14 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
593
594 * dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
595
596 * e2fsck.h: Include <time.h> since it is needed
597
598 * super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
599 processing.
600
Theodore Ts'o24dd4021998-02-01 00:16:40 +0000601Tue Jan 20 15:37:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
602
603 * unix.c (main): In the case where the filesystem revision is too
604 high, print the message about the superblock possibly
605 being corrupt.
606
607 * e2fsck.8.in: Add expanded comments about how the -b option
608 works.
609
Theodore Ts'o54dc7ca1998-01-19 14:50:49 +0000610Sat Jan 17 13:02:16 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
611
612 * e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
613 the ext2-specific header files are in a flat directory.
614
615 * dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
616 super.c, swapfs.c, unix.c: Explicitly cast all assignments
617 from void * to be compatible with C++.
618
619Tue Jan 6 11:30:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
620
621 * unix.c (sync_disk): Remove sync_disk and calls to that function,
622 since ext2fs_close() now takes care of this.
623
624Mon Dec 29 14:45:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
625
626 * pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
627 ehandler.c, unix.c: Change use of private to be priv_data,
628 to avoid C++ reserved name clash.
629
Theodore Ts'o5be8dc21997-12-01 18:24:10 +0000630Fri Nov 28 09:30:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
631
632 * dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
633 of e2fsck_get_num_dirs, which has been removed.
634
635Tue Nov 25 15:54:35 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
636
637 * Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
638 to compile and install flushb.
639
Theodore Ts'o7fdfabd1997-11-24 11:51:17 +0000640Mon Nov 24 06:48:00 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
641
642 * pass1.c (e2fsck_pass1_check_device_inode): For now, only check
643 to make sure the extra i_blocks in a device are cleared if
644 the immutable flag is set.
645
646 * util.c (print_resource_track): Fix typo which caused the
647 time/resource tracking to print "Pass 1 :" instead of
648 "Pass 1: ".
649
Theodore Ts'ob8647fa1997-11-20 21:52:43 +0000650Thu Nov 20 16:02:23 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
651
652 * pass3.c (expand_directory): Fix bug which could cause core dump
653 when expanding the directory, and the bitmaps hadn't yet
654 been read in. Also, only use ext2fs_write_dir_block when
655 writing a directory block, not when writing out a fresh
656 indirect block.
657
Theodore Ts'o8039c481997-11-19 21:39:13 +0000658Wed Nov 19 16:15:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
659
660 * pass1.c (process_bad_block): Fix bug where first_block wasn't
661 getting incremented, which caused user to get a
662 "Programming error?" warning if there was a bad block in a
663 non-primary superblock/group_descriptor. Also fixed
664 another bug so that ext2fs_bg_has_super() is consulted, to
665 avoid problems when using a filesystem with the
666 sparse_groups option set and there are bad blocks at the
667 beginning of a group which doesn't have a superblock.
668
Theodore Ts'of8188ff1997-11-14 05:23:04 +0000669Thu Nov 6 16:10:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
670
671 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the
672 progress indicator function.
673
674 * pass1.c (scan_callback): Add call to the progress feedback
675 function (if it exists).
676
677Tue Nov 4 09:45:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
678
679 * super.c (check_super_block): Skip the device size check if the
680 get_device_size returns EXT2_EXT_UNIMPLEMENTED.
681
682 * iscan.c (main): Don't use fatal_error() anymore.
683
684 * pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
685 calling fatal_error(0).
686
687 * problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
688 PR_3_NO_ROOT_INODE_ABORT): New problem codes.
689
690 * problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
691
692 * problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
693
694 * problemP.h: New file which separates out the private fix_problem
695 data structures.
696
697 * util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
698 swapfs.c util.c: allocate_memory() now takes a e2fsck
699 context as its first argument, and rename it to be
700 e2fsck_allocate_memory().
701
Theodore Ts'o08b21301997-11-03 19:42:40 +0000702Mon Nov 3 14:35:29 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
703
Theodore Ts'o68227541997-11-04 04:25:22 +0000704 * unix.c (main): Add a special case check for the error code EROFS
705 and display an appropriate error message for this case.
706
Theodore Ts'o08b21301997-11-03 19:42:40 +0000707 * [lots of files]: Change ext2fs_read_inode, ext2fs_write_inode
708 to take the e2fsck context as their first argument.
709 Change dir_info.c routines to take an e2fsck_context,
710 renamed them to start with e2fsck_ to avoid namespace
711 issues, and changed them to store the directory
712 information inside the e2fsck context.
713 Added e2fsck_run() which calls all of the e2fsck passes in
714 the correct order, and which handles the return of abort
715 codes. Added abort processing, both via setjmp/longjmp
716 and via flags in the e2fsck context. Use a flag in the
717 e2fsck context instead of the restart_e2fsck global
718 variable. Change uses of free and malloc to
719 ext2fs_free_mem and ext2fs_get_mem.
720
Theodore Ts'o291c9041997-10-31 06:17:08 +0000721Fri Oct 31 01:12:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
722
723 * pass1.c, pass3.c: Rename new error codes to _ET_ in them for
724 consistency.
725
Theodore Ts'oc555aeb1997-10-25 04:16:53 +0000726Sat Oct 25 00:10:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
727
728 * pass3.c (get_lost_and_found): Check error return of
729 EXT2_FILE_NOT_FOUND instead of ENOTDIR
730
731 * pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
732 instead of ENOTDIR
733
Theodore Ts'o622f5f21997-10-24 04:18:21 +0000734Fri Oct 24 00:12:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
735
Theodore Ts'o519149f1997-10-25 03:49:49 +0000736 * unix.c (PRS): Make the variable which getopt returns into be
737 an int, so that it won't lose on platforms where char is
738 unsigned.
739
Theodore Ts'o622f5f21997-10-24 04:18:21 +0000740 * pass1b.c (clone_file): Fix bug in error reporting in the case
741 where cs.errcode is non-zero.
742
Theodore Ts'ob2da22d1997-10-20 01:16:35 +0000743Sun Oct 19 21:12:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
744
Theodore Ts'o8bf191e1997-10-20 01:38:32 +0000745 * pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
746 RESOURCE_TRACK around code which uses init_resource_track
747 and print_resource_track. (Not all systems have timeval)
748
Theodore Ts'ob2da22d1997-10-20 01:16:35 +0000749 * super.c: Remove excess #includes which are not necessary.
750
751 * e2fsck.h: Add #ifdef's for HAVE_SYS_TYPES_H and HAVE_SYS_TIME_H
752
Theodore Ts'o1b6bf171997-10-03 17:48:10 +0000753Fri Oct 3 13:40:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
754
755 * pass*.c, super.c: Massive changes to avoid using printf and
756 com_err routines. All diagnostic messages are now routed
757 through the fix_problem interface.
758
759Sat Sep 6 17:13:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
760
761 * pass2.c (check_dir_block): Check for duplicate '.' and '..'
762 entries.
763
764 * problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
765 PR_2_DUP_DOT_DOT.
766
767Tue Sep 2 09:04:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
768
769 * problem.c: Added new problem codes for some of the
770 superblock corruption checks, and for the pass header
771 messages. ("Pass 1: xxxxx")
772
773 * util.c (print_resource_track): Now takes a description
774 argument.
775
776Mon Aug 25 10:23:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
777
778 * super.c, unix.c, e2fsck.c: New files to separate out the
779 operating-specific operations out from e2fsck.c.
780 e2fsck.c now contains the global e2fsck context management
781 routines, and super.c contains the "pass 0" initial
782 validation of the superblock and global block group
783 descriptors.
784
785 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
786 (nearly) all global variables and moved them to the e2fsck
787 context structure.
788
789 * problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
790 PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS,
791 PR_0_BLOCKS_PER_GROUP, PR_0_FIRST_DATA_BLOCK

816
817 * pass1.c (mark_table_blocks): Mark the superblock and group
818 descriptor blocks first, so that any conflicts between
819 these and the bitmap or inode table blocks is noticed.
820
821 * problem.c: Fix message printed out when a block or inode bitmap
822 conflicts with other fs data, has the correct group number
823 in it.
824
Theodore Ts'o7ac02a51997-06-11 18:32:35 +0000825Tue Jun 10 12:07:37 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

830
Theodore Ts'o583ccdc1997-05-09 03:06:31 +0000831 * e2fsck.8.in: Fix minor typos and grammer oops found by Bill
832 Hawes (whawes@star.net).
833
Theodore Ts'of635d7f1997-05-09 02:50:16 +0000834 * badblocks.c (read_bad_blocks_file): Pass the blocksize to the

836 tested in the case where the blocksize 2048 or 4096.
837
Theodore Ts'oa29f4d31997-04-29 21:26:48 +0000838Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>

841
842Mon Apr 21 22:43:08 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
843
844 * pass1b.c (pass1b): While scanning for inodes, simply skip inodes
845 where ext2fs_get_next_inode returns the
846 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE error.
847
848Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

857
858 * pass1b.c (clone_file_block): If we clone a directory, we need to
859 update the dblist entry so that we check (and correct) the
860 right directory block.
861
862Sun Apr 6 09:13:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
863
864 * pass1.c (process_block): Don't clear blocks references to
865 filesystem metadata; let pass 1B handle this case.
866
867 * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
868
869 * pass1b.c (pass1d): Deal with a block which is shared with
870 filesystem metadata.
871

876 * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
877 feature.
878 (get_backup_sb): New function which attempts to obtain the
879 correct backup superblock (if possible).
880
881Fri Apr 4 10:46:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
882
883 * e2fsck.c (main): Check the version of the library, and warn if
884 the library is out of date; this happens generally due to
885 users who manually install e2fsprogs.
886
887 * pass1.c (pass1_get_blocks): If the passed in inode number for
888 get_blocks isn't what we're expecting pass back
889 EXT2_ET_CALLBACK_NOT_HANDLED.
890
Theodore Ts'o21c84b71997-04-29 16:15:03 +0000891Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
892
893 * Release of E2fsprogs version 1.07
894
895Tue Mar 11 10:31:47 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
896
897 * icount.c: New file which implements an inode count abstraction.
898 This significantly reduces amount of memory needed to
899 check really large filesystems.
900
901 * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
902 abstraction.
903
904Fri Mar 7 08:28:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
905
906 * dirinfo.c (dir_info_iter): New function which allows iteration
907 over the directories in the dir_info map.
908
909 * pass3.c (pass3, check_directory): Speed up pass 3 by iterating
910 over all directories in the dir_info structure, instead of
911 iterating all inodes looking for directories, and then
912 looking up the directories using get_dir_info().
913
914Sat Feb 1 11:33:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
915
916 * pass1.c (pass1, process_block):
917 * pass2.c (pass2): Use the ext2_dblist abstraction instead of
918 manual code to manage the directory block list information.
919
920 * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
921 (deallocate_inode): Call the ext2 library routine
922 ext2_inode_has_valid_blocks() instead of
923 inode_has_valid_blocks().
924
925 * swapfs.c (swap_inodes): Add check so that we don't try to call
926 swap_inode_blocks unless the inode has valid blocks.
927 (Otherwise a long fast symlink might cause
928 swap_inode_blocks to erroneously get called.)
929
930Wed Jan 22 14:42:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
931
932 * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
933 PR_2_DOT_DOT_NULL_TERM.
934
935 * pass2.c (check_dot, check_dot_dot): Make sure the new . and
936 .. entries are null-terminated, since the 2.0 kernel
937 requires this (for no good reason).
938
939Mon Jan 20 20:05:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
940
941 * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
942 that we can recover from missing inode tables.
943
944 * dirinfo.c (get_dir_info): If there are no directories in the
945 dir_info abstraction, don't core dump (because dir_info is
946 NULL).
947
948 * e2fsck.c (main): Don't try using the backup superblocks if there
949 aren't any.
950 (check_super_block): If there are illegal inode table or
951 bitmaps, set the filesystem as being in error.
952
953Wed Jan 15 11:32:01 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
954
955 * pass2.c (check_dir_block): Added check to make sure that rec_len
956 is a a multiple of 4 (so that the directory entries are
957 4-byte aligned).
958
959Sat Dec 28 12:16:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
960
961 * Makefile.in (uninstall): Uninstall all programs in the PROGS
962 line.
963 (PROGS): Don't build and install the extend program by
964 default.
965
966
967Sat Dec 7 16:41:02 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
968
969 * pass1.c (process_inodes): Make sure the stashed_ino variable is
970 saved and restored as well.
971 (pass1): For fast sym links, skip the check_blocks
972 processing step altogether.
973
974Mon Dec 2 09:28:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
975
976 * problem.c, message.c: New files, to completely refurbish how
977 filesystem problems are reported to the user. The
978 diagnostic messages are now encoded out in an easily
979 customizable, extensible format. The messages printed out
980 in preen mode are all on one line, and contain the device
981 name.
982
983Fri Nov 29 20:26:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
984
985 * swapfs.c (swap_inodes): When swapping a filesystem, ignore
986 deleted files.
987
988 * pass1.c (pass1): Ignore missing inode table errors during the
989 scan, and just skip past those inodes.
990
991 * pass3.c (check_root): Remove root_ino argument, and assume that
992 the root inode must be EXT2_ROOT_INO. Move responsibility
993 of setting the parent of the root inode in the directory
994 inode structure to pass2().
995
996 * pass2.c (check_dir_block): Don't allow links to the root
997 directory.
998
999 * dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
1000 since the inode is no longer used.
1001
1002Tue Oct 15 00:06:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1003
1004 * e2fsck.c (main): If the superblock magic number is wrong, or the
1005 block group fails a sanity check, then automatically
1006 restart trying to use the backup superblocks.
1007
1008 * pass1.c (mark_table_blocks): Make the inode tables ahead of
1009 everything else; in the case where a bitmap block overlays
1010 the inode table, the inode table should take precedence.
1011
1012 * pass2.c (maybe_clear_entry): Make the deleted/unused error
1013 message fit on one line, since the error can happen during
1014 a preen pass. (We eventually need to revamp the whole
1015 e2fsck error reporting and prompting system, but that's a
1016 job for another day.)
1017
1018Mon Oct 14 22:29:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1019
1020 * e2fsck.c (main): Read in the list badblocks into fs->badblocks
1021 for the benefit of the inode scan functions.
1022
1023 * pass1.c (pass1): If ext2fs_get_next_inode() returns an error
1024 indicating that an inode is in a bad block, mark that
1025 inode as being used, as well as in the inode "bb" map.
1026
1027 * pass2.c (maybe_clear_entry): New function which generalizes the
1028 error cases when a directory entry needs to be cleared.
1029 (check_dir_block): If an inode is in the "bb" map, offer
1030 to clear the directory entry, since the inode is in a bad
1031 block.
1032
1033 * pass4.c (pass4): If an inode is marked as used, but is is marked
1034 in the "bb" map, don't process it as a disconnected inode.
1035
1036Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1037
1038 * Release of E2fsprogs version 1.06
1039
Theodore Ts'o5c576471997-04-29 15:29:49 +00001040Mon Oct 7 00:45:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1041
1042 * e2fsck.c (main): Print out the version number of the shared
1043 library when using the -V option.
1044
1045 * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
1046 consistency's sake.
1047
1048 * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
1049 out the backup superblocks when we know we have a valid
1050 filesystem.
1051
1052Tue Oct 1 22:00:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1053
1054 * util.c (preenhalt): Make it explicit on preenhalt that running
1055 e2fsck manually means without the -a or -p flag.
1056
1057Fri Sep 27 14:41:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1058
1059 * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
1060 (Linux/FT actually sets the mode bits, so we have to
1061 handle it specially.)
1062
1063 * e2fsck.c (check_if_skip): Print a message if the filesystem is
1064 just dirty, so that the user knows that it's about to be
1065 checked (since this will take a while).
1066
1067Mon Sep 16 17:00:01 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1068
1069 * pass4.c: If a disconnected inode is zero-length, prompt to
1070 delete it instead of connecting it to lost+found.
1071
1072Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1073
1074 * Release of E2fsprogs version 1.05
1075
Theodore Ts'o1e3472c1997-04-29 14:53:37 +00001076Fri Aug 30 20:24:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1077
1078 * pass4.c (pass4): If the user refuses to connect an unattached
1079 inode to lost+found, don't try to set i_links_count. This
1080 is bad, since if the user says yes, the inode will be
1081 marked as unused, which is not necessarily the right
1082 thing, especially since the rest of the cleanup doesn't
1083 happen here.
1084
1085 * pass2.c (deallocate_inode): Set inode_link_info[ino] when
1086 dellocating an inode. (Not strictly necessary, but...)
1087
1088 * pass4.c (pass4): Add "bonehead" explanation to the "programming
1089 error" message.
1090
1091Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1092
1093 * e2fsck.c (PRS,main): Added new options -s and -S. -s will
1094 byte-swap the filesystem so that it is normalized. -S
1095 will byte-swap the filesystem regardless of its current
1096 byte-order.
1097
1098 * swapfs.c: New file, which will byte-swap a filesystem.
1099
1100Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1101
1102 * pass1.c (pass1): Change handling on files with non-zero dtime
1103 and non-zero i_link_count; before we treated them as
1104 deleted file per botched ext2 0.3c kernel behavior. We
1105 now clear dtime instead.
1106
1107Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1108
1109 * e2fsck.c (main): If e2fsck sets the clean bit, even if
1110 nothing else is changed, make sure FSCK_NONDESTRUCT is
1111 set (since after all having the filesystem set to
1112 invalid is an error. :-)
1113
1114Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1115
1116 * pass1.c (process_block): Make sure that meta data doesn't get
1117 accidentally set in the dir_blocks array (which could
1118 happen in some error condtions).
1119
1120 * pass1.c (pass1):
1121 * pass2.c (process_bad_inode): Check for fragments in a
1122 OS-independent fashion.
1123
1124Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1125
1126 * e2fsck.c (check_if_skip): Close the filesystem when skipping the
1127 cleanup for the filesystem.
1128
1129Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1130
1131 * e2fsck.c: Improve corrupt_msg, so that it's less confusing.
1132
Theodore Ts'o62c06f71997-04-29 14:34:47 +00001133Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1134
1135 * Release of E2fsprogs version 1.04
1136
1137Wed May 15 21:41:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1138
1139 * e2fsck.c (relocate_hint): Issue a hint that the user may wish to
1140 try "e2fsck -b 8193" before allowing e2fsck to relocate
1141 inode table blocks.
1142
1143 * Makefile.in (e2fsck): Build e2fsck statically or dynamically
1144 depending on the option to configure. Added targets for
1145 e2fsck.static and e2fsck.shared for people who want to
1146 build a static or shared variant manually.
1147
Theodore Ts'o7f88b041997-04-26 14:48:50 +00001148Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
1149
1150 * Release of E2fsprogs version 1.03
1151
1152Tue Mar 26 12:03:42 1996 <tytso@rsts-11.mit.edu>
1153
1154 * e2fsck.c (show_stats): Don't use floating point to display
1155 percentage of non-contiguous files, as different libc
1156 handle result truncation differently, and this causes the
1157 test suite to bomb out depending on which libc you are
1158 using.
1159
1160 * util.c (allocate_memory): Fix error message to omit extraneous
1161 %%s.
1162
1163Tue Mar 5 03:50:40 1996 <tytso@rsts-11.mit.edu>
1164
1165 * pass4.c (pass4):
1166 * pass2.c (check_dir_block):
1167 * pass1.c (pass1): Add support for dynamic first inode revision.
1168
1169Wed Feb 14 16:27:30 1996 <tytso@rsts-11.mit.edu>

1172
1173Mon Feb 5 22:30:30 1996 <tytso@rsts-11.mit.edu>
1174
1175 * e2fsck.c (check_super_block): If the superblock fails certain
1176 internal consistency checks, exit with a fatal error after
1177 printing the "superblock is corrupt message".
1178
Theodore Ts'o74becf31997-04-26 14:37:06 +00001179Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1180
1181 * Release of E2fsprogs version 1.02
1182
1183Wed Dec 15 21:24:26 1996 <tytso@rsts-11.mit.edu>
1184
1185 * pass1.c (process_block): Check to see if a file is "fragmented".
1186 i.e., non-contiguous. Note that any file which is larger
1187 than the block group is guaranteed to be non-contiguous.
1188 We may want to use a different hueristic for deciding
1189 whether or not a file is "fragmented".
1190
1191 * e2fsck.c (show_stats): Print statistics of how many
1192 non-contiguous files are on the system.
1193
1194Fri Dec 15 19:19:47 1995 <tytso@rsts-11.mit.edu>
1195
1196 * badblocks.c (read_bad_blocks_file, test_disk): Fold
1197 functionality of test_disk() (which runs badblocks) into
1198 read_bad_blocks_file(); test_disk() now calls
1199 read_bad_blocks_file() with a NULL bad_blocks_file
1200 argument.
1201
1202Mon Nov 20 18:30:10 1995 <tytso@rsts-11.mit.edu>
1203
1204 * e2fsck.c (check_mount): Use #if defined(__linux__) instead of
1205 #if defined(linux). The latter won't work if we're
1206 compiling -ansi.
1207
Theodore Ts'o297f47a1997-04-26 14:25:20 +00001208Mon Oct 30 20:31:17 1995 <tytso@rsts-11.mit.edu>
1209
1210 * e2fsck.c (check_mount): For Linux systems, the check to see if
1211 the root is mounted read-only has to be done for all
1212 filesystems, not just for the root filesystem, due to the
1213 way that some /etc/rc scripts are set up.
1214
Theodore Ts'o50e1e101997-04-26 13:58:21 +00001215Thu Oct 26 12:05:30 1995 <tytso@rsts-11.mit.edu>
1216
1217 * Makefile.in (install): Strip programs when they are installed.
1218 (e2fsck): Build e2fsck statically.
1219
1220Wed Oct 25 21:18:16 1995 <tytso@rsts-11.mit.edu>
1221
1222 * util.c (preenhalt): Preenhalt now takes an argument, which is an
1223 ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
1224 flag in the superblock in cases where preenhalt is called.
1225 All calls to preenhalt() were changed to either
1226 preenhalt(fs) or preenhalt(NULL) in a few cases where the
1227 fs pointer was not available. (Most notable, for block
1228 read/write errors.)
1229
1230Mon Sep 4 21:41:03 1995 Remy Card <card@bbj>
1231
1232 * ehandler.c:
1233 util.c: Include <sys/time.h> before <sys/resource.h>. BSD needs it.
1234
1235Mon Sep 4 10:14:49 1995 <tytso@rsts-11.mit.edu>
1236
1237 * e2fsck.c (show_stats): Show statistics about how many inodes
1238 have indirect, doubly indirect, and triply indirect
1239 blocks. Allow up to 8 digits for statistics, instead of
1240 merely 6, so things look pretty for large filesystems.
1241
1242 * pass1.c (pass1): Keep statistics about indirect, doubly
1243 indirect, and triply indirect blocks.
1244
1245 * pass1.c (unwind_pass1): Clear the above statistics when unwinding
1246 pass 1.
1247
1248Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o <tytso@dcl>
1249
1250 * util.c, ehandler.c: Move #include of <sys/resource.h> after
1251 #include of "e2fsck.h", since sys/resource.h may depend on
1252 sys/time.h, which is #included in e2fsck.h.
1253
1254Thu Aug 17 22:33:37 1995 <tytso@rsts-11.mit.edu>
1255
1256 * e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted()
1257 function to determine if the device is mounted.
1258
1259 * e2fsck.c (main): Add better error messages if ext2fs_open()
1260 fails.
1261
1262Wed Aug 16 16:25:02 1995 <tytso@rsts-11.mit.edu>
1263
1264 * pass1.c (check_blocks): If we're clearing a directory, clear
1265 pb.is_dir so we don't do the following check of making
1266 sure the directory size matches; this is pointless, since
1267 we've already cleared the inode.
1268
1269Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1270
1271 * pass1.c (bad_primary_block): New function, called by
1272 process_bad_block, which explains the facts of life to the
1273 user when a block in the primary superblock or primary
1274 group descriptors is bad.
1275
1276 * pass2.c (check_dot): Handle the case where the first directory
1277 entry is used, but not ".".
1278
1279 * pass2.c (check_dotdot): Handle the case where the second directory
1280 entry is used, but is not "..".
1281
1282Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1283
1284 * e2fsck.c (check_super_block): Get the size of the physical
1285 device and if it is smaller than the reported size of the
1286 filesystem, report an error.
1287
1288Sat Aug 12 03:39:18 1995 Remy Card <card@bbj>
1289
1290 * e2fsck.c (check_if_skip): Print the number of allocated files and
1291 blocks on clean filesystems.
1292
1293Fri Aug 11 14:15:36 1995 Remy Card <card@bbj>
1294
1295 * e2fsck.8: Updated date and version number.
1296
1297Thu Aug 10 14:26:01 1995 Remy Card <card@bbj>
1298
1299 * pass1.c (check_blocks): Check that directory size matches *exactly*
1300 the count of allocated blocks.
1301
1302Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o <tytso@dcl>
1303
1304 * pass1b.c (pass1d): Free the shared[] array when we're done with
1305 it to avoid a memory leak.
1306
1307 * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
1308 block_dup_map.
1309
1310 * pass2.c (process_bad_inode): When clearing the inode, make sure
1311 the pathname is freed, to prevent a memory leak.
1312
1313 * pass5.c (check_inode_bitmaps): Free free_array and dir_array
1314 when we're finished with them.
1315 (check_block_bitmaps): Free free_array when we're finished
1316 with them.
1317
1318 * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
1319 linking the executable.
1320
1321 * pass2.c (process_bad_inode): Even on OS's that don't support the
1322 fragment fields, make sure the Linux equivalent fields are
1323 set to zero. If an OS wants to reuse these fields, which
1324 is probably a bad idea (although we may get desperate in
1325 the future) this code will have to be changed.
1326
1327 * pass1.c (dir_block_cmp): If the block numbers are equal, compare
1328 on the inode field, and then blockcnt field. This is just
1329 to keep the ordering of dir_blocks the same on all
1330 platforms when there are more than on missing directory
1331 blocks, which are indicated directories with holes, which
1332 are indicated with the block number being set to zero.
1333
1334Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1335
1336 * pass1.c (check_blocks, process_block): check_blocks() modified
1337 to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
1338 the inode is a directory. process_block() now checks to
1339 see if a directory has a "hole", or missing block. If so,
1340 this fact is recorded in the directory block list so that
1341 the problem can be resolved in pass #2.
1342
1343 * pass2.c (allocate_dir_block): Added allocate_dir_block() to
1344 allocate new blocks for directories with "holes". Called
1345 out of check_dir_block if a block in the directory block
1346 list is zero.
1347
1348 * pass3.c (get_lost_and_found): Move location of free(block) to
1349 prevent possible memory leak.
1350
1351Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1352
1353 * pass2.c (check_dir_block): Use a automatic, fixed-saize array
1354 instead of alloca() --- alloca is not portable! Check to
1355 make sure the filename is not longer than EXT2_NAME_LEN,
1356 and offer to fix it by truncating it, since it should
1357 never happen.
1358
1359 * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
1360 not portable!! In any case putenv() in some systems must
1361 take a static character array or malloc()'ed memory;
1362 passing memory allocated using alloca() to putenv() is not
1363 advisable.
1364
1365 * pass2.c (check_dot, check_dotdot): Use malloc() instead of
1366 alloca() --- alloca() is not portable!!!
1367
1368Tue Jul 18 20:04:02 1995 <tytso@rsx-11.mit.edu>
1369
1370 * pass1b.c (pass1c):
1371 * pass3.c (check_root, get_lost_and_found):
1372 * pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block
1373 to read/write the directory block.
1374
1375Mon Jul 17 04:00:56 1995 <tytso@rsx-11.mit.edu>
1376
1377 * util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to
1378 make sure VMIN and VTIME are set correct.
1379
1380Fri Jul 14 19:26:29 1995 <tytso@rsx-11.mit.edu>
1381
1382 * pass1.c (mark_block_used): Change to be an inline function.
1383 Assume that the block validity checks are already done,
1384 and use the fast variant of the bitmap functions.
1385
1386Thu Jul 13 08:10:55 1995 <tytso@rsx-11.mit.edu>
1387
1388 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
1389 bounds of the bitmaps in advance, and then use the fast
1390 variant of e2fs_test_{block,inode}_bitmap.
1391
1392 * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
1393 the bounds checking has already been done earlier.
1394
1395Wed Jul 12 02:22:46 1995 <tytso@rsx-11.mit.edu>
1396
1397 * pass1.c (pass1): Allocate and free the block_illegal_map, which
1398 is used for shortcut processing in process_block.
1399 (mark_table_blocks): Initialize block_illegal_map with the
1400 filesystem blocks.
1401 (describe_illegal_block): New helper function that
1402 describes why a block is illegal.
1403 (process_block): Use block_illegal_map as a shortcut
1404 to determine whether a block is bad. Use
1405 describe_illegal_block to print out why the block is illegal.
1406
1407Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl)
1408
1409 * flushb.c: Don't include <linux/fs.h> if it doesn't exist.
1410
1411 * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
1412 <mntent.h> if they don't exist. (Mostly so that "make
1413 depend" works.)
1414
1415 * pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
1416 it exists).
1417
1418 * e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
1419 exist.
1420
1421Mon Jun 12 08:37:49 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1422
1423 * pass2.c (process_bad_inode, check_for_zero_long,
1424 check_for_zero_char): Change long to u32, and char to u8.
1425
1426Sun Jun 11 15:05:57 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1427
1428 * util.c (inode_has_valid_blocks):
1429 * pass2.c (process_bad_inode):
1430 * pass1.c (pass1, check_blocks, pass1_check_directory): Use
1431 LINUX_S_IS* instead of S_IS*.
1432
1433 * e2fsck.h: Don't #include <sys/stat.h>
1434
1435 * flushb.c (main): Add #ifdef BLKFLSBUF around ioctl. (Although
1436 this program is pretty much useless if BLKFLSBUF isn't
1437 supported.)
1438
1439 * e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
1440 used.
1441
1442Thu Jun 8 12:31:19 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1443
1444 * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
1445 to allocate space for file names instead of using fixed size buffers.
1446 (process_bad_inode): Only check inode frag fields if
1447 HAVE_EXT2_FRAGS is defined (by configure).
1448 * pass1.c (pass1): Only check the inode frag fields if
1449 HAVE_EXT2_FRAGS is defined (by configure).
1450
1451 * e2fsck.c (check_mount): Only check for a mounted filesystem if
1452 HAVE_MNTENT_H is defined (by configure).
1453 (PRS): Use alloca to allocate the new path string, instead of
1454 having a fixed size buffer (which was the wrong size anyway).
1455 (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
1456 is defined.
1457
1458 * e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
1459 defined (by configure).
1460
1461 * Makefile.in: Rewritten to conform to GNU coding standards and
1462 support separate compilation directories.
1463
1464Thu Apr 6 15:04:36 1995 Remy Card <card@bbj.ibp.fr>
1465
1466 * pass1.c (pass1): Test the mode in reserved inodes (must be zero).
1467
Theodore Ts'of3db3561997-04-26 13:34:30 +00001468Sat Mar 11 13:12:16 1995 Theodore Y. Ts'o <tytso@localhost>
1469
1470 * pass1.c (unwind_pass1): Clear the file type statistics counter
1471 when pass 1 needs to be restarted from scratch.
1472
1473 * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
1474 being reallocated to blocks in the next block group,
1475 instead of the current block grup.
1476
1477 * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
1478 inode.i_links_count is set.
1479
1480Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11)
1481
1482 * pass1.c (process_block): Add checks for if the block is
1483 trepassing on a superblock or group descriptor table.
1484
1485Sat Dec 31 00:52:11 1994 <tytso@rsx-11.mit.edu>
1486
1487 * main.c (corrupt_msg): Extend the message which is printed out
1488 when the superblock is corrupt, to include the suggestion
1489 of using the -b option to specify an alternate superblock.
1490
1491Thu Nov 24 09:29:58 1994 Theodore Y. Ts'o (tytso@rt-11)
1492
1493 * badblocks.c (read_bad_blocks_file): If we are adding or
1494 replacing bad blocks in the bad blocks inode, sanity check
1495 the bad block inode first, and clear out any illegal blocks.
1496
1497 * pass2.c (check_name): Don't bomb out if the attempt to get the
1498 pathname of the containing directory returns an error; the
1499 directory may be too badly damaged to expect that
1500 ext2fs_get_pathname will always succeed. Use "???" if the
1501 pathname can't be obtained (it's only for a printf to the
1502 user anyway).
1503
1504 The name of the containing directory and the bad filename
1505 were incorrectly interchanged in the user message. Fixed.
1506
1507 * pass2.c (check_name, check_dir_block): Use a common static
1508 string for the unknown pathname.
1509
1510Mon Nov 7 22:30:54 1994 Remy Card <card@bbj>
1511
1512 * Fixed lots of printf formats to make sure that block and inode
1513 numbers are printed as unsigned integers.
1514
1515Mon Oct 24 14:10:46 1994 (tytso@rsx-11)
1516
1517 * pass5.c (check_block_end): Fix calculation of how the last block
1518 in the block bitmap should be calculated.
1519
1520Wed Sep 7 10:01:13 1994 (tytso@rsx-11)
1521
1522 * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to
1523 be an ext2fs_inode_bitmap, and free it properly.
1524
1525 * e2fsck.h
1526 * e2fsck.c (main): Folded in Remy Card's changes to add a revision
1527 level to the superblock.
1528
1529Wed Aug 17 22:00:20 1994 Remy Card (card@bbj)
1530
1531 * e2fsck.c (usage): Fixed bogus usage message.
1532
1533Wed Aug 17 11:21:45 1994 Theodore Y. Ts'o (tytso@rt-11)
1534
1535 * pass1.c (process_bad_block): Fixed bug so that blocks in the
1536 backup superblocks and group descriptors are handled gracefully.
1537
