   1 Thu Apr 10 13:51:16 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
   2
   3         * pass1b.c (clone_file_block): If we clone a directory, we need to
   4                 update the dblist entry so that we check (and correct) the
   5                 right directory block.
   6
   7 Sun Apr  6 09:13:12 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
   8
   9         * pass1.c (process_block): Don't clear blocks references to
  10                 filesystem metadata; let pass 1B handle this case.
  11
  12         * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
  13
  14         * pass1b.c (pass1d): Deal with a block which is shared with
  15                 filesystem metadata.
  16
  17         * e2fsck.h: Make block_illegal_map be a global variable
  18
  19 Sat Apr  5 11:51:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  20
  21         * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
  22                 feature.
  23                 (get_backup_sb): New function which attempts to obtain the
  24                 correct backup superblock (if possible).
  25
  26 Fri Apr  4 10:46:26 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  27
  28         * e2fsck.c (main): Check the version of the library, and warn if
  29                 the library is out of date; this happens generally due to
  30                 users who manually install e2fsprogs.
  31
  32         * pass1.c (pass1_get_blocks): If the passed in inode number for
  33                 get_blocks isn't what we're expecting pass back
  34                 EXT2_ET_CALLBACK_NOT_HANDLED.
  35
  36 Wed Mar 12 13:32:05 1997  Theodore Y. Ts'o  <tytso@mit.edu>
  37
  38         * Release of E2fsprogs version 1.07
  39
  40 Tue Mar 11 10:31:47 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  41
  42         * icount.c: New file which implements an inode count abstraction.
  43                 This significantly reduces amount of memory needed to
  44                 check really large filesystems.
  45
  46         * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
  47                 abstraction.
  48
  49 Fri Mar  7 08:28:55 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  50
  51         * dirinfo.c (dir_info_iter): New function which allows iteration
  52                 over the directories in the dir_info map.
  53
  54         * pass3.c (pass3, check_directory): Speed up pass 3 by iterating
  55                 over all directories in the dir_info structure, instead of
  56                 iterating all inodes looking for directories, and then
  57                 looking up the directories using get_dir_info().
  58
  59 Sat Feb  1 11:33:43 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  60
  61         * pass1.c (pass1, process_block):
  62         * pass2.c (pass2): Use the ext2_dblist abstraction instead of
  63                 manual code to manage the directory block list information.
  64
  65         * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
  66                 (deallocate_inode): Call the ext2 library routine
  67                 ext2_inode_has_valid_blocks() instead of
  68                 inode_has_valid_blocks().
  69
  70         * swapfs.c (swap_inodes): Add check so that we don't try to call
  71                 swap_inode_blocks unless the inode has valid blocks.
  72                 (Otherwise a long fast symlink might cause
  73                 swap_inode_blocks to erroneously get called.)
  74
  75 Wed Jan 22 14:42:53 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  76
  77         * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
  78                 PR_2_DOT_DOT_NULL_TERM.
  79
  80         * pass2.c (check_dot, check_dot_dot): Make sure the new . and
  81                 .. entries are null-terminated, since the 2.0 kernel
  82                 requires this (for no good reason).
  83
  84 Mon Jan 20 20:05:11 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  85
  86         * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
  87                 that we can recover from missing inode tables.
  88
  89         * dirinfo.c (get_dir_info): If there are no directories in the
  90                 dir_info abstraction, don't core dump (because dir_info is
  91                 NULL).
  92
  93         * e2fsck.c (main): Don't try using the backup superblocks if there
  94                 aren't any.
  95                 (check_super_block): If there are illegal inode table or
  96                 bitmaps, set the filesystem as being in error.
  97
  98 Wed Jan 15 11:32:01 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
  99
 100         * pass2.c (check_dir_block): Added check to make sure that rec_len
 101                 is a a multiple of 4 (so that the directory entries are
 102                 4-byte aligned).
 103
 104 Sat Dec 28 12:16:32 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 105
 106         * Makefile.in (uninstall): Uninstall all programs in the PROGS
 107                 line.
 108                 (PROGS): Don't build and install the extend program by
 109                 default.
 110
 111
 112 Sat Dec  7 16:41:02 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 113
 114         * pass1.c (process_inodes): Make sure the stashed_ino variable is
 115                 saved and restored as well.
 116                 (pass1): For fast sym links, skip the check_blocks
 117                 processing step altogether.
 118
 119 Mon Dec  2 09:28:24 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 120
 121         * problem.c, message.c: New files, to completely refurbish how
 122                 filesystem problems are reported to the user.  The
 123                 diagnostic messages are now encoded out in an easily
 124                 customizable, extensible format.  The messages printed out
 125                 in preen mode are all on one line, and contain the device
 126                 name.
 127
 128 Fri Nov 29 20:26:08 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 129
 130         * swapfs.c (swap_inodes): When swapping a filesystem, ignore
 131                 deleted files.
 132
 133         * pass1.c (pass1): Ignore missing inode table errors during the
 134                 scan, and just skip past those inodes.
 135
 136         * pass3.c (check_root): Remove root_ino argument, and assume that
 137                 the root inode must be EXT2_ROOT_INO.  Move responsibility
 138                 of setting the parent of the root inode in the directory
 139                 inode structure to pass2().
 140
 141         * pass2.c (check_dir_block): Don't allow links to the root
 142                 directory.
 143
 144         * dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
 145                 since the inode is no longer used.
 146
 147 Tue Oct 15 00:06:49 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 148
 149         * e2fsck.c (main): If the superblock magic number is wrong, or the
 150                 block group fails a sanity check, then automatically
 151                 restart trying to use the backup superblocks.
 152
 153         * pass1.c (mark_table_blocks): Make the inode tables ahead of
 154                 everything else; in the case where a bitmap block overlays
 155                 the inode table, the inode table should take precedence.
 156
 157         * pass2.c (maybe_clear_entry): Make the deleted/unused error
 158                 message fit on one line, since the error can happen during
 159                 a preen pass.  (We eventually need to revamp the whole
 160                 e2fsck error reporting and prompting system, but that's a
 161                 job for another day.)
 162
 163 Mon Oct 14 22:29:49 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 164
 165         * e2fsck.c (main): Read in the list badblocks into fs->badblocks
 166                 for the benefit of the inode scan functions.
 167
 168         * pass1.c (pass1): If ext2fs_get_next_inode() returns an error
 169                 indicating that an inode is in a bad block, mark that
 170                 inode as being used, as well as in the inode "bb" map.
 171
 172         * pass2.c (maybe_clear_entry): New function which generalizes the
 173                 error cases when a directory entry needs to be cleared.
 174                 (check_dir_block): If an inode is in the "bb" map, offer
 175                 to clear the directory entry, since the inode is in a bad
 176                 block.
 177
 178         * pass4.c (pass4): If an inode is marked as used, but is is marked
 179                 in the "bb" map, don't process it as a disconnected inode.
 180
 181 Tue Oct  8 02:02:03 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 182
 183         * Release of E2fsprogs version 1.06
 184
 185 Mon Oct  7 00:45:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 186
 187         * e2fsck.c (main): Print out the version number of the shared
 188                 library when using the -V option.
 189
 190         * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
 191                 consistency's sake.
 192
 193         * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
 194                 out the backup superblocks when we know we have a valid
 195                 filesystem.
 196
 197 Tue Oct  1 22:00:29 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 198
 199         * util.c (preenhalt): Make it explicit on preenhalt that running
 200                 e2fsck manually means without the -a or -p flag.
 201
 202 Fri Sep 27 14:41:08 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 203
 204         * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
 205                 (Linux/FT actually sets the mode bits, so we have to
 206                 handle it specially.)
 207
 208         * e2fsck.c (check_if_skip): Print a message if the filesystem is
 209                 just dirty, so that the user knows that it's about to be
 210                 checked (since this will take a while).
 211
 212 Mon Sep 16 17:00:01 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 213
 214         * pass4.c: If a disconnected inode is zero-length, prompt to
 215                 delete it instead of connecting it to lost+found.
 216
 217 Thu Sep 12 15:23:07 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 218
 219         * Release of E2fsprogs version 1.05
 220
 221 Fri Aug 30 20:24:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 222
 223         * pass4.c (pass4): If the user refuses to connect an unattached
 224                 inode to lost+found, don't try to set i_links_count.  This
 225                 is bad, since if the user says yes, the inode will be
 226                 marked as unused, which is not necessarily the right
 227                 thing, especially since the rest of the cleanup doesn't
 228                 happen here.
 229
 230         * pass2.c (deallocate_inode): Set inode_link_info[ino] when
 231                 dellocating an inode.  (Not strictly necessary, but...)
 232
 233         * pass4.c (pass4): Add "bonehead" explanation to the "programming
 234                 error" message.
 235
 236 Tue Aug 27 11:26:32 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 237
 238         * e2fsck.c (PRS,main): Added new options -s and -S.  -s will
 239                 byte-swap the filesystem so that it is normalized.  -S
 240                 will byte-swap the filesystem regardless of its current
 241                 byte-order.
 242
 243         * swapfs.c: New file, which will byte-swap a filesystem.
 244
 245 Tue Aug 20 09:41:37 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 246
 247         * pass1.c (pass1): Change handling on files with non-zero dtime
 248                 and non-zero i_link_count; before we treated them as
 249                 deleted file per botched ext2 0.3c kernel behavior.  We
 250                 now clear dtime instead.
 251
 252 Mon Aug 19 23:33:57 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 253
 254         * e2fsck.c (main): If e2fsck sets the clean bit, even if
 255                 nothing else is changed, make sure FSCK_NONDESTRUCT is
 256                 set (since after all having the filesystem set to
 257                 invalid is an error.  :-)
 258
 259 Fri Aug  9 10:25:13 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 260
 261         * pass1.c (process_block): Make sure that meta data doesn't get
 262                 accidentally set in the dir_blocks array (which could
 263                 happen in some error condtions).
 264
 265         * pass1.c (pass1):
 266         * pass2.c (process_bad_inode): Check for fragments in a
 267                 OS-independent fashion.
 268
 269 Thu Aug  8 15:20:54 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 270
 271         * e2fsck.c (check_if_skip): Close the filesystem when skipping the
 272                 cleanup for the filesystem.
 273
 274 Mon Jul 22 22:03:28 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 275
 276         * e2fsck.c: Improve corrupt_msg, so that it's less confusing.
 277
 278 Thu May 16 11:12:30 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 279
 280         * Release of E2fsprogs version 1.04
 281
 282 Wed May 15 21:41:29 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
 283
 284         * e2fsck.c (relocate_hint): Issue a hint that the user may wish to
 285                 try "e2fsck -b 8193" before allowing e2fsck to relocate
 286                 inode table blocks.
 287
 288         * Makefile.in (e2fsck): Build e2fsck statically or dynamically
 289                 depending on the option to configure.  Added targets for
 290                 e2fsck.static and e2fsck.shared for people who want to
 291                 build a static or shared variant manually.
 292
 293 Wed Mar 27 00:33:40 1996    <tytso@rsts-11.mit.edu>
 294
 295         * Release of E2fsprogs version 1.03
 296
 297 Tue Mar 26 12:03:42 1996    <tytso@rsts-11.mit.edu>
 298
 299         * e2fsck.c (show_stats): Don't use floating point to display
 300                 percentage of non-contiguous files, as different libc
 301                 handle result truncation differently, and this causes the
 302                 test suite to bomb out depending on which libc you are
 303                 using.
 304
 305         * util.c (allocate_memory): Fix error message to omit extraneous
 306                 %%s.
 307
 308 Tue Mar  5 03:50:40 1996    <tytso@rsts-11.mit.edu>
 309
 310         * pass4.c (pass4):
 311         * pass2.c (check_dir_block):
 312         * pass1.c (pass1): Add support for dynamic first inode revision.
 313
 314 Wed Feb 14 16:27:30 1996    <tytso@rsts-11.mit.edu>
 315
 316         * pass3.c (check_root): Fix spelling typo
 317
 318 Mon Feb  5 22:30:30 1996    <tytso@rsts-11.mit.edu>
 319
 320         * e2fsck.c (check_super_block): If the superblock fails certain
 321                 internal consistency checks, exit with a fatal error after
 322                 printing the "superblock is corrupt message".
 323
 324 Wed Jan 31 11:06:08 1996    <tytso@rsts-11.mit.edu>
 325
 326         * Release of E2fsprogs version 1.02
 327
 328 Wed Dec 15 21:24:26 1996    <tytso@rsts-11.mit.edu>
 329
 330         * pass1.c (process_block): Check to see if a file is "fragmented".
 331                 i.e., non-contiguous.  Note that any file which is larger
 332                 than the block group is guaranteed to be non-contiguous.
 333                 We may want to use a different hueristic for deciding
 334                 whether or not a file is "fragmented".
 335
 336         * e2fsck.c (show_stats): Print statistics of how many
 337                 non-contiguous files are on the system.
 338
 339 Fri Dec 15 19:19:47 1995    <tytso@rsts-11.mit.edu>
 340
 341         * badblocks.c (read_bad_blocks_file, test_disk): Fold
 342                 functionality of test_disk() (which runs badblocks) into
 343                 read_bad_blocks_file(); test_disk() now calls
 344                 read_bad_blocks_file() with a NULL bad_blocks_file
 345                 argument.
 346
 347 Mon Nov 20 18:30:10 1995    <tytso@rsts-11.mit.edu>
 348
 349         * e2fsck.c (check_mount): Use #if defined(__linux__) instead of
 350                 #if defined(linux).  The latter won't work if we're
 351                 compiling -ansi.
 352
 353 Mon Oct 30 20:31:17 1995    <tytso@rsts-11.mit.edu>
 354
 355         * e2fsck.c (check_mount): For Linux systems, the check to see if
 356                 the root is mounted read-only has to be done for all
 357                 filesystems, not just for the root filesystem, due to the
 358                 way that some /etc/rc scripts are set up.
 359
 360 Thu Oct 26 12:05:30 1995    <tytso@rsts-11.mit.edu>
 361
 362         * Makefile.in (install): Strip programs when they are installed.
 363                 (e2fsck): Build e2fsck statically.
 364
 365 Wed Oct 25 21:18:16 1995    <tytso@rsts-11.mit.edu>
 366
 367         * util.c (preenhalt): Preenhalt now takes an argument, which is an
 368                 ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
 369                 flag in the superblock in cases where preenhalt is called.
 370                 All calls to preenhalt() were changed to either
 371                 preenhalt(fs) or preenhalt(NULL) in a few cases where the
 372                 fs pointer was not available.  (Most notable, for block
 373                 read/write errors.)
 374
 375 Mon Sep  4 21:41:03 1995  Remy Card  <card@bbj>
 376
 377         * ehandler.c:
 378           util.c: Include <sys/time.h> before <sys/resource.h>.  BSD needs it.
 379
 380 Mon Sep  4 10:14:49 1995    <tytso@rsts-11.mit.edu>
 381
 382         * e2fsck.c (show_stats): Show statistics about how many inodes
 383                 have indirect, doubly indirect, and triply indirect
 384                 blocks.  Allow up to 8 digits for statistics, instead of
 385                 merely 6, so things look pretty for large filesystems.
 386
 387         * pass1.c (pass1): Keep statistics about indirect, doubly
 388                 indirect, and triply indirect blocks.
 389
 390         * pass1.c (unwind_pass1): Clear the above statistics when unwinding
 391                 pass 1.
 392
 393 Fri Aug 18 15:17:10 1995  Theodore Y. Ts'o  <tytso@dcl>
 394
 395         * util.c, ehandler.c: Move #include of <sys/resource.h> after
 396                 #include of "e2fsck.h", since sys/resource.h may depend on
 397                 sys/time.h, which is #included in e2fsck.h.
 398
 399 Thu Aug 17 22:33:37 1995    <tytso@rsts-11.mit.edu>
 400
 401         * e2fsck.c (check_mount):  Use the new ext2fs_check_if_mounted()
 402                 function to determine if the device is mounted.
 403
 404         * e2fsck.c (main):  Add better error messages if ext2fs_open()
 405                 fails.
 406
 407 Wed Aug 16 16:25:02 1995    <tytso@rsts-11.mit.edu>
 408
 409         * pass1.c (check_blocks): If we're clearing a directory, clear
 410                 pb.is_dir so we don't do the following check of making
 411                 sure the directory size matches; this is pointless, since
 412                 we've already cleared the inode.
 413
 414 Fri Aug 11 09:08:54 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 415
 416         * pass1.c (bad_primary_block): New function, called by
 417                 process_bad_block, which explains the facts of life to the
 418                 user when a block in the primary superblock or primary
 419                 group descriptors is bad.
 420
 421         * pass2.c (check_dot): Handle the case where the first directory
 422                 entry is used, but not ".".
 423
 424         * pass2.c (check_dotdot): Handle the case where the second directory
 425                 entry is used, but is not "..".
 426
 427 Thu Aug 10 10:05:10 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 428
 429         * e2fsck.c (check_super_block): Get the size of the physical
 430                 device and if it is smaller than the reported size of the
 431                 filesystem, report an error.
 432
 433 Sat Aug 12 03:39:18 1995  Remy Card  <card@bbj>
 434
 435         * e2fsck.c (check_if_skip): Print the number of allocated files and
 436                 blocks on clean filesystems.
 437
 438 Fri Aug 11 14:15:36 1995  Remy Card  <card@bbj>
 439
 440         * e2fsck.8: Updated date and version number.
 441
 442 Thu Aug 10 14:26:01 1995  Remy Card  <card@bbj>
 443
 444         * pass1.c (check_blocks): Check that directory size matches *exactly*
 445                 the count of allocated blocks.
 446
 447 Wed Aug  9 21:21:24 1995  Theodore Y. Ts'o  <tytso@dcl>
 448
 449         * pass1b.c (pass1d): Free the shared[] array when we're done with
 450                 it to avoid a memory leak.
 451
 452         * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
 453                 block_dup_map.
 454
 455         * pass2.c (process_bad_inode): When clearing the inode, make sure
 456                 the pathname is freed, to prevent a memory leak.
 457
 458         * pass5.c (check_inode_bitmaps): Free free_array and dir_array
 459                 when we're finished with them.
 460                 (check_block_bitmaps): Free free_array when we're finished
 461                 with them.
 462
 463         * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
 464                 linking the executable.
 465
 466         * pass2.c (process_bad_inode): Even on OS's that don't support the
 467                 fragment fields, make sure the Linux equivalent fields are
 468                 set to zero.  If an OS wants to reuse these fields, which
 469                 is probably a bad idea (although we may get desperate in
 470                 the future) this code will have to be changed.
 471
 472         * pass1.c (dir_block_cmp): If the block numbers are equal, compare
 473                 on the inode field, and then blockcnt field.  This is just
 474                 to keep the ordering of dir_blocks the same on all
 475                 platforms when there are more than on missing directory
 476                 blocks, which are indicated directories with holes, which
 477                 are indicated with the block number being set to zero.
 478
 479 Sun Aug  6 15:40:58 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 480
 481         * pass1.c (check_blocks, process_block): check_blocks() modified
 482                 to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
 483                 the inode is a directory.  process_block() now checks to
 484                 see if a directory has a "hole", or missing block.  If so,
 485                 this fact is recorded in the directory block list so that
 486                 the problem can be resolved in pass #2.
 487
 488         * pass2.c (allocate_dir_block): Added allocate_dir_block() to
 489                 allocate new blocks for directories with "holes".  Called
 490                 out of check_dir_block if a block in the directory block
 491                 list is zero.
 492
 493         * pass3.c (get_lost_and_found): Move location of free(block) to
 494                 prevent possible memory leak.
 495
 496 Sat Aug  5 12:42:22 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 497
 498         * pass2.c (check_dir_block): Use a automatic, fixed-saize array
 499                 instead of alloca() --- alloca is not portable!  Check to
 500                 make sure the filename is not longer than EXT2_NAME_LEN,
 501                 and offer to fix it by truncating it, since it should
 502                 never happen.
 503
 504         * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
 505                 not portable!!  In any case putenv() in some systems must
 506                 take a static character array or malloc()'ed memory;
 507                 passing memory allocated using alloca() to putenv() is not
 508                 advisable.
 509
 510         * pass2.c (check_dot, check_dotdot): Use malloc() instead of
 511                 alloca() --- alloca() is not portable!!!
 512
 513 Tue Jul 18 20:04:02 1995    <tytso@rsx-11.mit.edu>
 514
 515         * pass1b.c (pass1c):
 516         * pass3.c (check_root, get_lost_and_found):
 517         * pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block
 518                 to read/write the directory block.
 519
 520 Mon Jul 17 04:00:56 1995    <tytso@rsx-11.mit.edu>
 521
 522         * util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to
 523                 make sure VMIN and VTIME are set correct.
 524
 525 Fri Jul 14 19:26:29 1995    <tytso@rsx-11.mit.edu>
 526
 527         * pass1.c (mark_block_used): Change to be an inline function.
 528                 Assume that the block validity checks are already done,
 529                 and use the fast variant of the bitmap functions.
 530
 531 Thu Jul 13 08:10:55 1995    <tytso@rsx-11.mit.edu>
 532
 533         * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
 534                 bounds of the bitmaps in advance, and then use the fast
 535                 variant of e2fs_test_{block,inode}_bitmap.
 536
 537         * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
 538                 the bounds checking has already been done earlier.
 539
 540 Wed Jul 12 02:22:46 1995    <tytso@rsx-11.mit.edu>
 541
 542         * pass1.c (pass1): Allocate and free the block_illegal_map, which
 543                 is used for shortcut processing in process_block.
 544                 (mark_table_blocks): Initialize block_illegal_map with the
 545                 filesystem blocks.
 546                 (describe_illegal_block): New helper function that
 547                 describes why a block is illegal.
 548                 (process_block): Use block_illegal_map as a shortcut
 549                 to determine whether a block is bad.  Use
 550                 describe_illegal_block to print out why the block is illegal.
 551
 552 Mon Jun 12 19:11:06 1995  Theodore Y. Ts'o  (tytso@dcl)
 553
 554         * flushb.c: Don't include <linux/fs.h> if it doesn't exist.
 555
 556         * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
 557                 <mntent.h> if they don't exist.  (Mostly so that "make
 558                 depend" works.)
 559
 560         * pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
 561                 it exists).
 562
 563         * e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
 564                 exist.
 565
 566 Mon Jun 12 08:37:49 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 567
 568         * pass2.c (process_bad_inode, check_for_zero_long,
 569                 check_for_zero_char):  Change long to u32, and char to u8.
 570
 571 Sun Jun 11 15:05:57 1995  Theodore Y. Ts'o  <tytso@lurch.mit.edu>
 572
 573         * util.c (inode_has_valid_blocks):
 574         * pass2.c (process_bad_inode):
 575         * pass1.c (pass1, check_blocks, pass1_check_directory): Use
 576                 LINUX_S_IS* instead of S_IS*.
 577
 578         * e2fsck.h: Don't #include <sys/stat.h>
 579
 580         * flushb.c (main): Add #ifdef BLKFLSBUF around ioctl.  (Although
 581                 this program is pretty much useless if BLKFLSBUF isn't
 582                 supported.)
 583
 584         * e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
 585                 used.
 586
 587 Thu Jun  8 12:31:19 1995  Miles Bader  <miles@churchy.gnu.ai.mit.edu>
 588
 589         * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
 590         to allocate space for file names instead of using fixed size buffers.
 591         (process_bad_inode): Only check inode frag fields if
 592         HAVE_EXT2_FRAGS is defined (by configure).
 593         * pass1.c (pass1): Only check the inode frag fields if
 594         HAVE_EXT2_FRAGS is defined (by configure).
 595
 596         * e2fsck.c (check_mount): Only check for a mounted filesystem if
 597         HAVE_MNTENT_H is defined (by configure).
 598         (PRS): Use alloca to allocate the new path string, instead of
 599         having a fixed size buffer (which was the wrong size anyway).
 600         (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
 601         is defined.
 602
 603         * e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
 604         defined (by configure).
 605
 606         * Makefile.in: Rewritten to conform to GNU coding standards and
 607         support separate compilation directories.
 608
 609 Thu Apr  6 15:04:36 1995  Remy Card  <card@bbj.ibp.fr>
 610
 611         * pass1.c (pass1): Test the mode in reserved inodes (must be zero).
 612
 613 Sat Mar 11 13:12:16 1995  Theodore Y. Ts'o  <tytso@localhost>
 614
 615         * pass1.c (unwind_pass1): Clear the file type statistics counter
 616                 when pass 1 needs to be restarted from scratch.
 617
 618         * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
 619                 being reallocated to blocks in the next block group,
 620                 instead of the current block grup.
 621
 622         * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
 623                 inode.i_links_count is set.
 624
 625 Tue Feb 14 01:38:04 1995  Theodore Y. Ts'o  (tytso@rt-11)
 626
 627         * pass1.c (process_block): Add checks for if the block is
 628                 trepassing on a superblock or group descriptor table.
 629
 630 Sat Dec 31 00:52:11 1994    <tytso@rsx-11.mit.edu>
 631
 632         * main.c (corrupt_msg): Extend the message which is printed out
 633                 when the superblock is corrupt, to include the suggestion
 634                 of using the -b option to specify an alternate superblock.
 635
 636 Thu Nov 24 09:29:58 1994  Theodore Y. Ts'o  (tytso@rt-11)
 637
 638         * badblocks.c (read_bad_blocks_file): If we are adding or
 639                 replacing bad blocks in the bad blocks inode, sanity check
 640                 the bad block inode first, and clear out any illegal blocks.
 641
 642         * pass2.c (check_name): Don't bomb out if the attempt to get the
 643                 pathname of the containing directory returns an error; the
 644                 directory may be too badly damaged to expect that
 645                 ext2fs_get_pathname will always succeed.  Use "???" if the
 646                 pathname can't be obtained (it's only for a printf to the
 647                 user anyway).
 648
 649                 The name of the containing directory and the bad filename
 650                 were incorrectly interchanged in the user message.  Fixed.
 651
 652         * pass2.c (check_name, check_dir_block): Use a common static
 653                 string for the unknown pathname.

 655 Mon Nov  7 22:30:54 1994  Remy Card  <card@bbj>
 656
 657         * Fixed lots of printf formats to make sure that block and inode
 658         numbers are printed as unsigned integers.

 660 Mon Oct 24 14:10:46 1994    (tytso@rsx-11)
 661
 662         * pass5.c (check_block_end): Fix calculation of how the last block
 663                 in the block bitmap should be calculated.
 664
 665 Wed Sep  7 10:01:13 1994    (tytso@rsx-11)
 666
 667         * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to
 668                 be an ext2fs_inode_bitmap, and free it properly.
 669
 670         * e2fsck.h
 671         * e2fsck.c (main): Folded in Remy Card's changes to add a revision
 672         level to the superblock.
 673
 674 Wed Aug 17 22:00:20 1994  Remy Card  (card@bbj)
 675
 676         * e2fsck.c (usage): Fixed bogus usage message.
 677
 678 Wed Aug 17 11:21:45 1994  Theodore Y. Ts'o  (tytso@rt-11)
 679
 680         * pass1.c (process_bad_block): Fixed bug so that blocks in the
 681         backup superblocks and group descriptors are handled gracefully.
