Theodore Ts'o | 508d7f3 | 2003-03-16 20:41:04 -0500 | [diff] [blame] | 2 | =================================== |
| 3 | |
Theodore Ts'o | ba142c1 | 2003-04-16 00:59:59 -0400 | [diff] [blame] | 4 | Added a new utility program, logsave, which captures the output of a |
| 5 | command in a log file, even if the containing directory hasn't been |
| 6 | mounted yet (in which case the it saves the output in memory until it |
| 7 | can write out the logfile). This is useful for capturing the |
| 8 | output of fsck during the boot sequence. |
| 9 | |
| 10 | Fixed some portability problems that were causing problems under |
| 11 | the Cygwin32 environment. |
| 12 | |
| 13 | Mke2fs now interprets a negative number to the -b option as a minimum |
| 14 | block size. |
| 15 | |
| 16 | Fixed a bug in mke2fs which was incorrectly checking the argument to |
| 17 | the -g option if the default block size was used. (Addresses Debian |
| 18 | bug #188319) |
| 19 | |
| 20 | Fsck now explicitly ignores tmpfs and devpts, and it will complain if |
| 21 | it can not find filesystem checkers for jfs, reseirfs, and xfs. |
| 22 | |
| 23 | E2fsck now updates the global free block and inode counters from the |
| 24 | block group specific counters quietly. This is needed for an |
| 25 | experimental patch which eliminates locking the entire filesystem when |
| 26 | allocating blocks or inodes; if the filesystem is not unmounted |
| 27 | cleanly, the global counts may not be accurate. |
| 28 | |
| 29 | Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS |
| 30 | 2.0 is not yet supported; this only pulled in the bug fixes: fixed |
| 31 | possible hangs caused by bugs in calling waitpid, and not setting the |
| 32 | pipe to non-blocking mode; also fixed a file descriptor leak; made |
| 33 | sure all functions call log entry/exit functions.) |
| 34 | |
| 35 | Badblocks now flushes its output file as bad blocks are discovered. |
| 36 | |
| 37 | The uuid library is now more paranoid about assuming the correctness |
| 38 | of the /dev/random device; it mixes in a stream of bytes from |
| 39 | random/srandom, just in case. |
| 40 | |
Theodore Ts'o | 39d38b0 | 2003-03-30 23:45:02 -0500 | [diff] [blame] | 41 | Update Debian files to reflect the fact that I am now the Debian |
Theodore Ts'o | ba142c1 | 2003-04-16 00:59:59 -0400 | [diff] [blame] | 42 | maintainer of e2fsprogs. Other various Debian-specific packaging |
| 43 | cleanups. |
Theodore Ts'o | 39d38b0 | 2003-03-30 23:45:02 -0500 | [diff] [blame] | 44 | |
| 45 | Move the source tarball generation functions from the top-level |
| 46 | makefile to the util/gen-tarball script. |
| 47 | |
| 48 | Updated the Turkish .po translation file. |
| 49 | |
| 50 | Added heimdall and MIT krb5 extensions to the com_err library to make |
| 51 | it more compatible with com_err libraries from those distributions. |
| 52 | |
| 53 | Changed dumpe2fs to always display the superblock fields relating to |
| 54 | the journalling and/or directory indexing feature even if those |
| 55 | features are not enabled. |
| 56 | |
Theodore Ts'o | 508d7f3 | 2003-03-16 20:41:04 -0500 | [diff] [blame] | 57 | Updated and clarify copyright statement vis-a-vis alpha releases of |
| 58 | e2fsprogs. |
| 59 | |
| 60 | The ss library will now try to dynamically link to the readline |
| 61 | library and use it if it is present in the system. This means that |
Theodore Ts'o | ba142c1 | 2003-04-16 00:59:59 -0400 | [diff] [blame] | 62 | the debugfs program now has line editing and history features. The |
| 63 | SS_READLINE_PATH environment variable is used to find a readline or |
| 64 | readline-compatible library. |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 65 | |
Theodore Ts'o | e5dced7 | 2003-03-15 04:28:17 -0500 | [diff] [blame] | 66 | E2fsck now finds most duplicate filenames (all when rebuilding all |
| 67 | directories via the -D option) and offers to delete or rename |
| 68 | duplicate filenames/directory entries. (Addresses Debian Bug #176814). |
| 69 | |
| 70 | Fix bug in e2image. When writing out a raw image file, include data |
| 71 | blocks from symlinks that do not store the symlink within the inode. |
| 72 | |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 73 | Fix bug in resize2fs which incorrectly moved the block and inode |
| 74 | bitmaps for sparse superblock filesystems and incorrectly marked |
| 75 | blocks as in use. (Addresses Debian bug #174766) |
| 76 | |
| 77 | Added a new shared library, the blkid library, which efficiently |
| 78 | allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL |
| 79 | and UUID filesystem specifiers without needing to search all of the |
| 80 | devices in the system. Instead, the device is looked up in a cache |
| 81 | file, and then verified to make sure the blkid cache is correct. |
| 82 | |
| 83 | Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for |
| 84 | the device name, using the blkid library. (Addresses Debian bugs |
| 85 | #166048, #179671) |
| 86 | |
| 87 | Fsck now supports backslash escapes in /etc/fstab so that \040 can be |
| 88 | used for spaces in device labels. |
| 89 | |
| 90 | Removed 32-bit limitations for debugfs's dump command. |
| 91 | |
| 92 | If the user specifies a large number of inodes, Mke2fs will |
| 93 | automatically adjust the number of blocks per group to find a valid |
| 94 | set of filesystem parameters. |
| 95 | |
| 96 | Add workaround to detect broken MD devices where when some of the |
| 97 | underlying devices are marked read-only, writes to the MD device are |
| 98 | silently dropped. E2fsck will detect if there is an attempt to run |
| 99 | the journal twice, and abort with an error if this is the case. |
| 100 | (Addresses IBM Bugzilla bug #1226) |
| 101 | |
| 102 | E2fsck will print an error if more than one of the -p/-a, -n or -y |
| 103 | options are specified. |
| 104 | |
| 105 | E2fsck will fix HTREE corruptions in preen mode, without stopping the |
| 106 | boot process. This is needed because the 2.4 ext2 filesystem |
| 107 | accidentally had the INDEX_FL backwards compatibility code removed. |
| 108 | |
| 109 | Mke2fs no longer creates filesystems with the dir_index flag set by |
| 110 | default; the user has to specifically request it. |
| 111 | |
| 112 | Update and clarified various man pages. (Addresses Debian bugs |
Theodore Ts'o | ba142c1 | 2003-04-16 00:59:59 -0400 | [diff] [blame] | 113 | #173612, #175233, #175113, and #170497, #185945, #188318) |

Theodore Ts'o | 508d7f3 | 2003-03-16 20:41:04 -0500 | [diff] [blame] | 115 | Created man page for the mk_cmds program (from the libss library). |
| 116 | |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 117 | Programmer's notes: |
| 118 | ------------------- |
| 119 | |
| 120 | Fix various gcc -Wall nits. |
| 121 | |
| 122 | Fixed a lot of portability problems that caused e2fsprogs not to build |
Theodore Ts'o | e5dced7 | 2003-03-15 04:28:17 -0500 | [diff] [blame] | 123 | successfully under Solaris and Apple/Darwin. |
| 124 | |
| 125 | Fixed a Makefile dependency to allow building e2fsprogs using parallel |
| 126 | make jobs. |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 127 | |
| 128 | Changes to create a subset distribution which consists only of the |
| 129 | et, ss, uuid, and blkid libraries. The configure script and top-level |
| 130 | makefile were changed to support working with a subset distribution. |
| 131 | |
Theodore Ts'o | ba142c1 | 2003-04-16 00:59:59 -0400 | [diff] [blame] | 132 | Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
| 133 | actually used, and might people who are looking for |
| 134 | EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. |
| 135 | |
Theodore Ts'o | 508d7f3 | 2003-03-16 20:41:04 -0500 | [diff] [blame] | 136 | Updated debian files to fix a number of Lintian warnings. |
| 137 | |
| 138 | Updated config.guess and config.sub with newer versions from the FSF. |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 139 | |
Theodore Ts'o | 71df0dc | 2003-04-21 16:17:09 -0400 | [diff] [blame] | 140 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
| 141 | chattr, and blkid executables. |
| 142 | |
Theodore Ts'o | 3851301 | 2002-11-09 15:00:56 -0500 | [diff] [blame] | 143 | E2fsprogs 1.32 (Nomvember 9, 2002) |
| 144 | ================================== |
| 145 | |
| 146 | Fixed a bug in the Unix I/O routines which caused needless writebacks |
| 147 | of clean blocks from the unix_io cache (they were erroneously marked |
| 148 | as being dirty, so they were getting written back to disk before |
| 149 | getting evicted from the disk cache). This was harmless, but it |
| 150 | significantly slowed down e2fsck. |
| 151 | |
| 152 | Made some other minor optimizations to the Unix I/O routines to save a |
| 153 | small amount of CPU time. |
| 154 | |
| 155 | Updated internationalization files. |
| 156 | |
Theodore Ts'o | 3809bf1 | 2003-03-07 01:09:57 -0500 | [diff] [blame] | 157 | |
Theodore Ts'o | ae65b29 | 2002-11-08 20:08:48 -0500 | [diff] [blame] | 158 | E2fsprogs 1.31 (Nomvember 8, 2002) |
| 159 | ================================== |
| 160 | |
| 161 | Update EVMS ext2fsim plugin with EVMS 1.2. (We still support |
| 162 | compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error |
| 163 | handling for child process that die unexpectly. Add a hack to force |
| 164 | mkfs to create filesystems that won't cause problems with hardware |
| 165 | that has 2k or 4k minimum blocksize requirements. Read from child |
| 166 | processes in non-blocking mode, so that the GUI continues to update. |
| 167 | |
| 168 | Fix e2fsck so that it returns the appropriate exit code when the root |
| 169 | filesystem has been changed, so that system's rc scripts will be told that |
| 170 | the system needs to be rebooted. |
| 171 | |
| 172 | Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag |
| 173 | was set, some of the descriptor blocks that should have been written |
| 174 | out were getting skipped. |
| 175 | |
| 176 | Changed e2fsck to force out changes to the backup copies of the |
| 177 | superblock and block group descriptors when important changes are made |
| 178 | to those data structures. |
| 179 | |
| 180 | Fix a bug where e2fsck could erroneously mark a filesystem as being |
| 181 | clean if a check of dirty filesystem is interrupted with a ^C. (Bug |
| 182 | introduced in e2fsprogs 1.28.) |
| 183 | |
| 184 | If journal debuging is enabled using --enable-jbd-debug, the debugging |
| 185 | level is now set via the E2FSCK_JBD_DEBUG environment variable. |
| 186 | |
| 187 | If byteswapping support is disabled using configure --disable-swapfs, |
| 188 | skip the tests which depend on byte-swapping, so that "make check" |
| 189 | won't bomb out. |
| 190 | |
| 191 | Lshattr will now display the indexed directory flag. Also, some of |
| 192 | the more esoteric compression flags are supressed unless compression |
| 193 | support has been enabled. |
| 194 | |
| 195 | Update man pages. |
| 196 | |
| 197 | |
Theodore Ts'o | 5d823a4 | 2002-11-01 02:13:53 -0500 | [diff] [blame] | 198 | E2fsprogs 1.30 (October 31, 2002) |
| 199 | ================================= |
| 200 | |
| 201 | When resizing a filesystem, and inodes need to moved, resize2fs will |
| 202 | update the inode's ctime field, and the mtime field of the containing |
| 203 | directories, so that incremental backups using dump/restore will work |
| 204 | correctly. |
| 205 | |
| 206 | In order to avoid spurious errors, e2fsck wil check the last |
| 207 | superblock write time to determine whether or not it can safely use |
| 208 | the LOW_DTIME checks to determine if there are inodes on the orphan |
| 209 | inode linked list that had somehow gotten disconnected. (Addresses |
| 210 | Sourceforge bug #620980) |
| 211 | |
| 212 | Partition in /proc/partitions that being with the string "lvm" are |
| 213 | considered real partitions even if they do not end with a number. |
| 214 | |
| 215 | Fixed a bug in the the uuid generation function, where if /dev/urandom |
| 216 | is not present, but /dev/random is, and there isn't sufficient |
| 217 | entropy, the get_random_byte function could spin a loop forever. |
| 218 | |
| 219 | E2fsck, mke2fs, etc. will now reliably notice when image files are |
| 220 | mounted using the loopback interface. (Addresses Sourceforge bug |
| 221 | #619119) |
| 222 | |
| 223 | When flushing buffers (as is done by badblocks, for example) check to |
| 224 | see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the |
| 225 | FDFLUSH ioctl which causes the MD device driver which causes confusing |
| 226 | syslog messages about obselete ioctl messages. (Addresses Sourceforge |
| 227 | bug #545832). |
| 228 | |
| 229 | Debugfs's write command now checks to see if the destination filename |
| 230 | exists before creating it. (Addresses Sourceforge bug #478195.) |
| 231 | |
| 232 | When installing man pages, search for compressed man pages using all |
| 233 | commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) |
| 234 | |
| 235 | Fixed a bug in fsck where multiple filesystems specified on the |
| 236 | command were not being checked in parallel due to a logic bug |
| 237 | introduced to support the FSCK_MAX_INST environment variable. |
| 238 | |
| 239 | We have added a new superblock field, s_mkfs_time, which indicates |
| 240 | when a filesystem was created. It is set via mke2fs, and printed out |
| 241 | by dumpe2fs, but is not actually touched by the kernel. |
| 242 | |
| 243 | Dumpe2fs has been made more robust by not aborting if there is an |
| 244 | error reading the block/inode bitmaps; instead it will still print out |
| 245 | the location of the block/inode bitmaps and inode table. |
| 246 | |
| 247 | Add support for the an alternative block group descriptor layout which |
| 248 | allows for on-line resizing without needing to prepare the filesystem |
| 249 | in advance. (This is the incomat feature flag meta_bg.) |
| 250 | |
| 251 | Add support for storing default mount options in the superblock, so |
| 252 | that the filesystem can be mounted with specific mount options without |
| 253 | needing to specify them on the mount command line or in the /etc/fstab |
| 254 | file. |
| 255 | |
| 256 | Add support for a new inode flag, which is to be used for indicating |
| 257 | the top of directory hierarchies for the Orlov block allocator. |
| 258 | |
| 259 | Fix e2fsck so that if it creates the lost+found directory, it does so |
| 260 | with the more apporpriate permissions of 0700. Also change |
| 261 | mklost+found so that it also creates the directory 0700. |
| 262 | |
| 263 | Fixed format bug in e2fsck if NLS is in use. |
| 264 | |
| 265 | Add a German translation for e2fsprogs's NLS support. |
| 266 | |
| 267 | Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at |
| 268 | the beginning of the inode table. This won't matter much, since if |
| 269 | there is a bad block at the beginning of the inode table, the root |
| 270 | directory won't be available. But at least e2fsck won't crash in this |
| 271 | case. |
| 272 | |
| 273 | Fixed endian problems in the htree code for e2fsck and debugfs. |
| 274 | |
| 275 | When byte-swapping a filesystem on a PPC architecture, byte-swap the |
| 276 | bitmaps since the historical big-endian ext2 variant had byte-swapped |
| 277 | bitmaps, and the ext2fs library assumes this. This fixes the |
| 278 | regression test suite on PPC machines. |
| 279 | |
| 280 | Fix e2image so that it handles a bad block in the inode table |
| 281 | appropriately. |
Theodore Ts'o | d5e7810 | 2002-09-30 11:33:36 -0400 | [diff] [blame] | 282 | |
| 283 | E2fsck now uses a more sophisticated algorithm to salvage corrupted |
| 284 | directories that recovers more information in the corrupted directory |
| 285 | block. |
| 286 | |
| 287 | E2fsck now performs additional consistency checks on indexed (HTREE) |
| 288 | directories. |
| 289 | |
| 290 | Fix bug where efsck might get confused about whether a completely |
| 291 | empty directory block is an empty leaf block or an interior htree |
| 292 | node. This could cause e2fsck to get confused into think that a valid |
| 293 | indexed directory was corrupted. |
| 294 | |
| 295 | E2fsck no longer creates an empty directory entry at the end of a |
| 296 | directory block when optimizing a directory. This would cause some |
| 297 | earlier versions of the dxdir kernel code to corrupt the directory |
| 298 | when attempting to split a node containing an empty directory entry. |
| 299 | |
| 300 | E2fsck could sometimes in rare circumstances leave the indexed flag |
| 301 | set after a small directory was optimized by compressing it instead of |
| 302 | indexing it. (This should never happen in real life, since |
| 303 | directories that small wouldn't have been indexed, but better safe |
| 304 | than sorry.) |
| 305 | |
| 306 | E2fsck now only updates the master superblock in all cases. This |
| 307 | slightly shortens its run time. |
| 308 | |
| 309 | Ext2ed can deal with directory entries of length 0; previously it |
| 310 | would get stuck in an infinite loop. |
| 311 | |
| 312 | Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= |
| 313 | specifiers. (Sourceforge patch #613447) |
| 314 | |
| 315 | Badblocks will now work correctly on read-only devices such as |
| 316 | CD-ROM's. (Sourceforge patch #600451) |
| 317 | |
Theodore Ts'o | 5d823a4 | 2002-11-01 02:13:53 -0500 | [diff] [blame] | 318 | Updated and clarified man pages. (Addresses Debian bug #167108) |

Theodore Ts'o | c663305 | 2002-09-24 01:26:50 -0400 | [diff] [blame] | 321 | E2fsprogs 1.29 (September 24, 2002) |
| 322 | =================================== |
| 323 | |
| 324 | Fixed a bug in e2fsck which could corrupt a directory when optimizing |
| 325 | it (via the -D option) or rebuiliding the hash tree index with a 1 in |
| 326 | 512 probability, due to a fence post error. |
| 327 | |
| 328 | Fixed a bug in the LVM support code which caused LABEL='xxx' not to |
| 329 | work correctly. |
| 330 | |
| 331 | Mke2fs now enables the directory indexing flag by default. (Since |
| 332 | this is a compatible feature flag, it's safe to do so.) |
| 333 | |
| 334 | Tune2fs will support setting the directory indexing feature flag. It |
| 335 | will automatically set up the default hash algorithm and hash seed |
| 336 | fields in the superblock. |
| 337 | |
| 338 | If the bone-headed user enters the root filesystem twice in |
| 339 | /etc/fstab, the -R option which skips the root filesystem will skip |
| 340 | all of them. (Addresses Debian bug #159423). Note! This is not a |
| 341 | precedent for dealing intelligently with any other kind of doubled |
| 342 | entry in /etc/fstab! |
| 343 | |
| 344 | |
| 345 | Programmer's notes: |
| 346 | ------------------- |
| 347 | |
| 348 | Removed perror declaration in lib/et/internal.h. All modern systems |
| 349 | can be expected to define perror() these days. Besides, the lib/et |
| 350 | code wasn't using perror at all anyway. :-) |

Theodore Ts'o | b7bad61 | 2002-08-31 03:00:33 -0400 | [diff] [blame] | 353 | E2fsprogs 1.28 (August 31, 2002) |
| 354 | ================================ |
| 355 | |
| 356 | Add support for the Hashed-Tree Directory Indexing to e2fsck. Support |
| 357 | for setting the htree flag is not included yet, although it can be |
| 358 | manually turned on via the debugfs program. |
| 359 | |
| 360 | Clarified e2fsck error message which is printed when it cannot find |
| 361 | sufficient contiguous block when relcating filesystem metadata. |
| 362 | |
| 363 | Added support for building an EVMS plugin module for ext2/3. This |
| 364 | module is substantially the same as the EVMS module shipping with EVMS |
| 365 | 1.1, with one or two bugfixes. E2fsprogs can also build this plugin |
| 366 | for use with EVMS 1.0 (which did not include the ext2 plugin module), |
| 367 | if the configure --enable-old-evms flag is given. |
| 368 | |
| 369 | Fsck will search through EVMS volumes when trying to resolve |
| 370 | filesystem specifications such as LABEL=xxx or UUID=xxx. |
| 371 | |
| 372 | Added a new utility program, /sbin/findfs, which will return |
| 373 | filesystem specifications such as LABEL=xxx or UUID=xxx, and prints |
| 374 | the device name. |
| 375 | |
| 376 | Update and clarified various man pages. (addresses Debian Bug #145044, |
| 377 | #146437, #131350, #151990, #144621, #141938) |
| 378 | |
| 379 | If there are no filesystems specified on fsck's command line, fsck now |
| 380 | treat that as if the -As options were given. Previously it would |
| 381 | simply do nothing. (Addresses Debian Bug #153102) |
| 382 | |
| 383 | Mke2fs no longer treats a failure to be able to clear the MD signature |
| 384 | at the end of the filesystem as a fatal error. (Addresses Debian Bug |
| 385 | #155007) |
| 386 | |
| 387 | The e2p library functions (which are used by lsattr and chattr) now |
| 388 | double check to make sure the file is a regular file or directory |
| 389 | before attempting to use the ext2 ioctls. Some device drivers |
| 390 | unfortunately respond to the ext2 ioctl's with unknown behaviour. |
| 391 | (Addresses Debian Bug #152029). |
| 392 | |
| 393 | The extended attribute handling has been updated to correspond with |
| 394 | the latest V2 bestbits ACL code. |
| 395 | |
| 396 | Fixed bug in e2fsck which caused it to not clear the dtime field when |
| 397 | processing truncated inodes on the orphan list. This could cause data |
| 398 | loss(!) if a filesystem is rebooted before a truncate has been |
| 399 | committed. |
| 400 | |
| 401 | E2fsck now uses red/black trees in pass1b, which removes some O(n**2) |
| 402 | algorithms. This makes e2fsck much faster in the case of severely |
| 403 | corrupted filesystems where a large number of blocks are claimed by a |
| 404 | large number of inodes. (Thanks to the 2.5 IDE device driver for |
| 405 | inspiring this work.) |
| 406 | |
| 407 | Resize2fs has been significantly sped up when shrinking and expanding |
| 408 | a filesystem by a very small number of blocks (for example, when EVMS |
| 409 | is converting a partition to be an EVMS legacy volume). |
| 410 | |
| 411 | Added a new option to e2fsck, -D, which will optimize or compress all |
| 412 | of the directories in the filesystem. |
| 413 | |
| 414 | E2fsck now catches SIGINT and SIGTERM to make sure it will can |
| 415 | properly clean up and only exit at safe points. Fsck will pass |
| 416 | SIGINT/SIGTERM to its child processes, and wait until they have all |
| 417 | exited before it exits. |
| 418 | |
| 419 | The uuid parsing code in the uuid library now properly complains when |
| 420 | an illegally formated uuid is presented to it. (Addresses Debian bug |
| 421 | #152891) |
| 422 | |
| 423 | Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 |
| 424 | and 2.4.17, since the workaround can cause problems when using a 2.4 |
| 425 | kernel with an old version of glibc built with the 2.2 headers. |
| 426 | |
| 427 | Fixed a bug in mke2fs where it wasn't properly clearing the initial |
| 428 | superblock used by other filesystems. (Addresses Debian bug #147256.) |
| 429 | |
| 430 | Added support for the synchronous directory feature written by Andrew |
| 431 | Morton. |
| 432 | |
| 433 | The debugfs program can delete directories using the rmdir command. |
| 434 | |
| 435 | Add support for 8k and 16k filesystems (for systems with page sizes |
| 436 | that are greater or equal to 8k or 16k, respectively). Note that |
| 437 | these filesystems can not be mounted on x86 systems, or other systems |
| 438 | with only 4k page sizes, due to limitations in the current Linux VM |
| 439 | code. |
| 440 | |
| 441 | Resize2fs requires that the filesystem state be valid and have no |
| 442 | errors; otherwise, e2fsck -f must be run first. (Previously it simply |
| 443 | required that the last fsck time be greater than the last mount time.) |
| 444 | |
| 445 | Configure now defaults the man pages directory to /usr/share/man on |
| 446 | Linux systems. |
| 447 | |
| 448 | E2fsck now offers to truncate inodes which contain too many blocks (so |
| 449 | that i_blocks would overflow. Also fixed handling of large sparse |
| 450 | files. |
| 451 | |
| 452 | E2fsck now more completely checks for symlink validity, including |
| 453 | requiring NULL termination and length checks. |
| 454 | |
| 455 | E2fsck will offer to try forcing a disk write to remap a bad block |
| 456 | after finding a read error when reading a filesystem metadata block. |
| 457 | |
| 458 | Fixed a bug in debugfs which caused the -b and -s options to crash |
| 459 | debugfs, as well as breaking the testb, setb, and clearb functions. |
| 460 | |
| 461 | Added a bmap command to debugfs which calculates the logical to |
| 462 | physical block mapping for a particular inode. |
| 463 | |
| 464 | Fixed a bug in code which checked to see if a device was mounted which |
| 465 | sometimes (rarely) failed in the case of a plain file. |
| 466 | |
| 467 | Fixed a bug in resize2fs where when it reported an error, it would |
| 468 | print a message erroneously indicating that the filesystem had been |
| 469 | resized before it aborted. |
| 470 | |
| 471 | When resizing a plain file which is smaller than the requested size, |
| 472 | resize2fs will attempt to extended the file so that programs like |
| 473 | e2fsck will not complain that the file is too small. |
| 474 | |
| 475 | Resize2fs will print the actual new size of the filesystem when it is |
| 476 | finished resizing. |
| 477 | |
| 478 | Fixed a bug in debugfs where "ls -l" would report incorrectl file type |
| 479 | information on big-endian systems. |
| 480 | |
| 481 | |
| 482 | Programmer's notes: |
| 483 | ------------------- |
| 484 | |
| 485 | Fixed collisions with C++ reserved words. |
| 486 | |
| 487 | Added portability fixes for building e2fsprogs on the HURD and AIX. |
| 488 | |
| 489 | Added the ext2ed program for creation of test cases. (ext2ed has many |
| 490 | limitations and bugs which make it unsuitable for production use.) |
| 491 | |
| 492 | The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new |
| 493 | flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the |
| 494 | name_len field is byte swampped on big-endian machines, since in the |
| 495 | V2 structure, name_len is a char field which is doesn't need to be |
| 496 | byte swapped --- except if an old-style kernel had byte-swapped the |
| 497 | name_len field as part of the V1 structure. |

| 501 | ============================== |
| 502 | |
| 503 | The warning messages for mke2fs now go to standard error. |
| 504 | |
| 505 | Fixed to make sure "make check" runs all of the test programs with |
| 506 | LD_LIBRARY_PATH set, so that we test the libraries in the build tree. |
| 507 | |
| 508 | The mke2fs program checks the boot sector for the BSD disk label, and |
| 509 | avoids erasing it if it is there. |
| 510 | |
| 511 | Fixed a bug in e2fsck which caused it to core dump if the journal |
| 512 | inode was missing when it was supposed to be there. |
| 513 | |
| 514 | E2fsck now prints ranges in pass 5 when printing deltas for the block |
| 515 | and inode bitmaps. |
Theodore Ts'o | afa14ba | 2002-03-05 03:31:06 -0500 | [diff] [blame] | 516 | |
| 517 | Debugfs's "ls -l" command now will print out the file type information |
| 518 | in the directory entry. |
| 519 | |
| 520 | Create man pages and hard links for fsck.ext3 and mkfs.ext3. If |
| 521 | mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. |
| 522 | |
| 523 | Debugfs can now examine the experimental directory indexing |
| 524 | information. |
| 525 | |
Theodore Ts'o | a471ac5 | 2002-03-05 03:37:06 -0500 | [diff] [blame] | 526 | Fixed bug in debugfs which caused it to core dump if modify_inode is |
| 527 | called without an open filesystem. |
| 528 | |
| 529 | The debugfs lsdel command now runs its output through a pager first. |
| 530 | |
Theodore Ts'o | afa14ba | 2002-03-05 03:31:06 -0500 | [diff] [blame] | 531 | When installing manual pages, remove the compressed manual pages first. |
| 532 | |
| 533 | Synchronized with Debian's packaging information for e2fsprogs-1.26-1. |
| 534 | |
| 535 | Fix the 2.4 resource limitation workaround introduced in 1.26 which |
| 536 | actually broke things on mips32, sparc32, and Alpha platforms. |
| 537 | |
Theodore Ts'o | a471ac5 | 2002-03-05 03:37:06 -0500 | [diff] [blame] | 538 | Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
| 539 | (which is required by the newer libintl libraries). |
| 540 | |
Theodore Ts'o | afa14ba | 2002-03-05 03:31:06 -0500 | [diff] [blame] | 541 | Programmer's notes: |

| 543 | |
Theodore Ts'o | a8e7724 | 2002-03-08 03:12:14 -0500 | [diff] [blame] | 544 | Fixed various gcc -Wall complaints. |
| 545 | |
Theodore Ts'o | afa14ba | 2002-03-05 03:31:06 -0500 | [diff] [blame] | 546 | Fixed a few memory leaks in the e2fsck journaling code, and in the |
| 547 | ismounted code checking for a swap device. |
| 548 | |
| 549 | Add new inode I/O abstraction interface which exports an inode as |
| 550 | an I/O object. |
| 551 | |
| 552 | Exported ext2_file_flush as a public interface. |
| 553 | |
| 554 | In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. |
| 555 | |
| 556 | Lots of small random portability fixes to make e2fsprogs build under |
| 557 | AIX --- even without the 5L compatibility toolkit, and even using the |
| 558 | uber-crippled AIX native C compiler. |
| 559 | |

Theodore Ts'o | a5f3f5c | 2002-02-03 01:00:22 -0500 | [diff] [blame] | 562 | ================================= |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 563 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 564 | Dumpe2fs will keep going now if the bad block inode can't be read. |
| 565 | (Previously it stopped with a fatal error.) |
| 566 | |
| 567 | E2fsck will now give an opportunity to run the journal even if the |
| 568 | recovery flag is not set. This is the default behaviour if e2fsck is |
| 569 | using a backup superblock, since the needs_recovery flag will never be |
| 570 | set in the backup superblock copies. |
| 571 | |
| 572 | E2fsck now automatically finds the backup superblock/group descriptors |
| 573 | even when the primary superblock is completely destroyed for 2k and 4k |
| 574 | filesystems. (Previously it just guessed/assumed that we were dealing |
| 575 | with a 1k filesystem in that case, and users had to manually specify |
| 576 | the backup superblock number.) |
| 577 | |
| 578 | Fixed a bug in e2fsck where it dereferences a null pointer when there |
| 579 | is a problem opening a filesystem in preen mode. |
| 580 | |
| 581 | E2fsck now handles external journals correctly; previously it trashed |
| 582 | the external journal device if the journal needed to be replayed. |
| 583 | |
| 584 | Work around ulimit incompatibility problem caused by recent 2.4 |
| 585 | kernels; the unix IO module will automatically try to set any resource |
| 586 | limits to be infinite on startup. |
| 587 | |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 588 | Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
| 589 | bitmap if it wasn't present and the blocksize was 2k or 4k. |
| 590 | (Addresses Debian Bug #116975) |
| 591 | |
| 592 | E2fsck will check and fix botched ext3 V1 to V2 superblock updates by |
| 593 | clearing the new V2 fields if they do not make sense or if the ext3 |
| 594 | superblock is version 1 superblock. |
| 595 | |
| 596 | E2fsck will automatically relocate the ext3 journal from a visible |
| 597 | file (i.e., /.journal) to an hidden inode if the filesystem has been |
| 598 | opened read/write. This allows the users to add a journal while the |
| 599 | filesystem is mounted, but the next time the system is rebooted, the |
| 600 | journal file will disappear. This avoids problems with backups, |
| 601 | stupid operators with superuser bits, etc. |
| 602 | |
| 603 | Fix a bug in fsck where it would not support a filesystem type of |
| 604 | "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. |
| 605 | |
Theodore Ts'o | a5f3f5c | 2002-02-03 01:00:22 -0500 | [diff] [blame] | 606 | Fsck now supports fstab entries of the form "ext3,ext2". It will also |
| 607 | automatically identify reiserfs filesystems. |
| 608 | |
| 609 | The number of processes spawned by fsck can now be limited using the |
| 610 | FSCK_MAX_INST environment variable. |
| 611 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 612 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
| 613 | should be searched for UUID and label information. |
| 614 | |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 615 | Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
| 616 | limit if at all possible, when opening a block device. (The filesize |
| 617 | limit shouldn't be applied against writes to a block device.) |
| 618 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 619 | In mke2fs and e2fsck, specifying the -c option twice will now do |
| 620 | a read/write test on the disk. Update the man pages to encourage |
| 621 | using the -c option, and to discouraging running badblocks separately, |
| 622 | since users tend to forget to set the blocksize when running |
| 623 | badblocks. |
| 624 | |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 625 | Mke2fs now automatically clears the immutable attribute on a |
| 626 | pre-existing .journal file left over from a previous failed attempt to |
| 627 | add a journal to an alreadyy-mounted filesystem. |
| 628 | |
| 629 | Fixed mke2fs's exit codes to consistently indicate when the mke2fs |
| 630 | operation failed. |
| 631 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 632 | Mke2fs now creates the lost+found directory with permissions of 0700, |
| 633 | so that files that had previously lived in protected directory are |
| 634 | safe if they get dropped in lost+found and the system administrator |
| 635 | doesn't deal with immediately. (Addresses Debian #bug 118443) |
| 636 | |
| 637 | Mke2fs and e2fsck (and all programs that use the |
| 638 | ext2fs_check_if_mounted function) will now properly identify that a |
| 639 | device is mounted, even in cases where devfs has confused things with |
| 640 | multiple devices names with the same identity, or if a dim-witted |
| 641 | system administrator has done something stupid like creating device |
| 642 | file aliases in their home directory. Also now checks for swap devices |
| 643 | by using /proc/swaps. (Addresses Debian bug #106622) |
| 644 | |
Theodore Ts'o | a5f3f5c | 2002-02-03 01:00:22 -0500 | [diff] [blame] | 645 | Added a new option (-T) to tune2fs which sets the time a filesystem |
| 646 | was last checked. |
| 647 | |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 648 | Speed up e2image when creating sparse raw image files by optimizing |
| 649 | away excess lseek() system calls. |
| 650 | |
| 651 | Fix support of large (> 2GB) files when used as a filesystem in |
| 652 | mke2fs, tune2fs, debugfs, and findsuper. |
| 653 | |
| 654 | Debugfs's stat and icheck commands now properly deals with large (> |
| 655 | 2GB) files. |
| 656 | |
| 657 | Debugfs's set_super_value command now prints out the list of valid |
| 658 | superblock fields which can be set using the command. |
| 659 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 660 | Debugfs's rm and kill_file command now updates the superblock free block |
| 661 | and inode counts, thus keeping the filesystem consistent. |
| 662 | |
Theodore Ts'o | a5f3f5c | 2002-02-03 01:00:22 -0500 | [diff] [blame] | 663 | Debugfs's lsdel command now takes an optional argument which allows |
| 664 | the user to only see the most recently deleted files. |
| 665 | |
| 666 | A new command (undel) was added to debugfs which automates |
| 667 | undeleting a deleted inode and linking it back to a directory. |
| 668 | |
| 669 | Debugfs's ls command now takes a new option, -d, which lists |
| 670 | deleted directory entries. |
| 671 | |
| 672 | Debugfs's testb, freeb, setb, and find_free_block commands now take an |
| 673 | optional count argument. |
| 674 | |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 675 | Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
| 676 | be used to signal that a particular inode should not be eligible for |
| 677 | tail-merging --- this is needed for programs like LILO. |
| 678 | |
| 679 | The findsuper (an unreleased, uninstalled utility program) has been |
| 680 | improved to add extra validity checks and to add a progress meter. |
| 681 | (It is still an unsupported program; the officially supported way to |
| 682 | recover from a trashed partition table is to use gpart; findsuper is |
| 683 | for wizards only. :-) |
| 684 | |
| 685 | Debugfs was fixed to compile with "configure --disable-swapfs". |
| 686 | |
Theodore Ts'o | 446314f | 2001-12-24 15:22:27 -0500 | [diff] [blame] | 687 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
Theodore Ts'o | cd1a79a | 2001-11-27 03:36:42 -0500 | [diff] [blame] | 688 | |
| 689 | Added new translation file for Turkish. |
| 690 | |

| 692 | ------------------- |
| 693 | |
| 694 | Fix general gcc -Wall complaints. |
| 695 | |
| 696 | E2fsprogs (mostly) works with the dietlibc. |
| 697 | |
| 698 | The programming texinfo file has been expanded to include description |
| 699 | of additional libext2fs functions. (Still not compeltely done, but a |
| 700 | lot of the more important functions have been documented.) |
| 701 | |
| 702 | Added a umask structure to struct_ext2_filsys, which currently only |
| 703 | modifies the behaviour of ext2fs_mkdir(), but if we add any file |
| 704 | creation functions to libext2fs, we should also make sure they respect |
| 705 | the umask setting. |
| 706 | |
Theodore Ts'o | a5f3f5c | 2002-02-03 01:00:22 -0500 | [diff] [blame] | 707 | The build-rpm script was fixed to be a bit more safe. |
| 708 | |
| 709 | The tests' Makefile now has a way of automating test case creation |
| 710 | for e2fsck, using "make testnew". |
| 711 | |
| 712 | Created a new function, ext2fs_dir_iterate2 which passes more |
| 713 | information to the callback function (identical to the one used by |
| 714 | ext2fs_dblist_dir_iterate). The directory iterator functions take a |
| 715 | new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted |
| 716 | directory entries. If the directory entry is deleted, the callback |
| 717 | function will be called with the entry paraemter set to |
| 718 | DIRENT_DELETED_FILE. |
| 719 | |
| 720 | Added new functions, ext2fs_inode_alloc_stats and |
| 721 | ext2fs_block_alloc_stats, which takes updates block/inode allocation |
| 722 | statistics in the bitmaps, block group descriptors, and superblock |
| 723 | when inodes or blocks are allocated or deallocated. |

Theodore Ts'o | d08a4ce | 2001-09-20 09:47:42 -0400 | [diff] [blame] | 726 | E2fsprogs 1.25 (September 20, 2001) |
| 727 | =================================== |
| 728 | |
| 729 | This is primarily a bug-fix release; no new features were added, but |
| 730 | there are a number of embarassing bug fixes and cleanups applied. |
| 731 | |
| 732 | Fix a bug mke2fs which causes stack garbage to be written to disk when |
| 733 | zapping disk sectors. (This bug could cause mke2fs to core dump for |
| 734 | some kernels, I suspect with security enhancement patches.) |
| 735 | |
| 736 | Remove unneeded #include of <linux/config.h> which was breaking |
| 737 | building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) |
| 738 | |
| 739 | Updated tune2fs man page to reflect the fact that adding or removing a |
| 740 | journal doesn't require running e2fsck. |
| 741 | |
| 742 | Remove use of AC_REQUIRE from autoconf which had been used to prevent |
| 743 | AC_CANONICAL_HOST from being called twice; unfortunately this causes |
| 744 | recent autoconf to bomb out since they don't allow AC_REQUIRE to be |
| 745 | used outside of autoconf macros. Fortunately, it doesn't seem to be |
| 746 | necessary any more, anyway. |
| 747 | |
| 748 | E2fsck will now not fall back to an alternate superblock if the user |
| 749 | specifies the superblock location explicitly on the command-line. |
| 750 | This allows easier recovery from a situation where the primary |
| 751 | superblock and block groups are slightly corrupted, but the backup |
| 752 | superblocks are completely broken. |
| 753 | |
| 754 | Fix problem which caused compile_et and mk_cmds to blow up if |
| 755 | e2fsprogs was in a directory with a pathname that contained spaces. |
| 756 | |
| 757 | We are now more paranoid about checking the entry in /etc/mtab to make |
| 758 | sure the filesystem is really mounted, since some broken distributions |
| 759 | (read: Slackware) don't initialize /etc/mtab before checking non-root |
| 760 | filesystems. (Slackware also doesn't check the root filesystem |
| 761 | separately, and reboot if the root filesystem had changes applied to |
| 762 | it, which is dangerous and broken, but there's nothing I can do about |
| 763 | that.) |
| 764 | |
| 765 | Make UUID library C++ friendly by adding appropriate extern "C" |
| 766 | declarations and using const in the function declarations. |
| 767 | |
| 768 | Fix up the com_err texinfo file so that it can product a valid info |
| 769 | file (previously, it could only be used to generate paper |
| 770 | documentation using texinfo.tex). |

| 774 | =================================== |
| 775 | |
| 776 | Fix brown-paper bug in mke2fs which caused it to segfault when |
| 777 | printing the version string. |
| 778 | |
| 779 | |
Theodore Ts'o | 109624a | 2001-08-31 00:59:55 -0400 | [diff] [blame] | 780 | E2fsprogs 1.24 (August 30, 2001) |
| 781 | ================================ |
| 782 | |
| 783 | Revert the BLKGETSIZE64 support, since for some distributions, this |
| 784 | ioctl has been used by an unofficial kernel patch to update the last |
| 785 | sector on the disk, and this was causing disk corruption problems as a |
| 786 | result. |
| 787 | |
| 788 | Mke2fs is now more careful about zapping swap space signatures and |
| 789 | other filesystem/raid superblock magic values so that programs like |
| 790 | mount who try to use hueristics to determine the filesystem type of a |
| 791 | partition are less likely to be confused. |
| 792 | |
| 793 | E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a |
| 794 | regular file (since Andreas Dilger's on-line resizing tools will set |
| 795 | its mode bits). |
| 796 | |
| 797 | Fixed some minor texinfo, man pages nits for spelling errors, |
| 798 | texinfo warnings, etc. (Addresses Debian bug #110621.) |
| 799 | |
| 800 | E2fsprogs program no longer print the filesystem version number |
| 801 | (i.e. 0.5b), since it only confuses people and doesn't serve any real |
| 802 | purpose. |
| 803 | |
| 804 | E2fsck will once again compile under libc5, since it will supply its |
| 805 | own version of strnlen if necesssary. |
| 806 | |
| 807 | mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers |
| 808 | when specifying the external journal device. tune2fs will also search |
| 809 | devices looking for the externla journal debice when removing. |
| 810 | |
| 811 | E2fsprogs 1.23 (August 15, 2001) |
| 812 | ================================ |
Theodore Ts'o | d1ef5c3 | 2001-07-20 12:35:11 -0400 | [diff] [blame] | 813 | |
| 814 | Add initial support for extended attributes (EA); e2fsck will |
Theodore Ts'o | 6c0a041 | 2001-07-23 00:23:52 -0400 | [diff] [blame] | 815 | correctly handle a filesystem with EA's and check the EA blocks for |
| 816 | corruptions. |
| 817 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 818 | E2fsck's symlink sanity checking has been cleaned up. It now checks |
| 819 | the i_size value of fast symlinks, and checks for immutable flags |
| 820 | being set of symlinks, etc. |
| 821 | |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 822 | E2fsck now offers to clear inodes which are special files that have a |
| 823 | non-zero i_blocks or i_size field. (The i_size field check was in the |
| 824 | previous version of the code, but due to a bug it didn't offer to |
| 825 | clear the inode unless i_size and i_size_high were both non-zero.) |
| 826 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 827 | E2image can now create "raw" image files, which only contain the |
| 828 | filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, |
| 829 | debugfs, etc., can be run directly on the raw image file. |
Theodore Ts'o | bf16d10 | 2001-07-27 22:20:06 -0400 | [diff] [blame] | 830 | |
| 831 | Add support for the 64-bit block device patches. |
| 832 | |
| 833 | Fixed bugs in creating external journals with a 1k blocksize. |
| 834 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 835 | Add initial support for external journals (so long as the external |
| 836 | journal only supports a single filesystem) in e2fsck. |
| 837 | |
| 838 | Remove requirement for needing to run fsck on a filesystem after |
| 839 | removing a journal (either internal or external). |
| 840 | |
Theodore Ts'o | bf16d10 | 2001-07-27 22:20:06 -0400 | [diff] [blame] | 841 | The man pages now document how to create and manage external journals. |
Theodore Ts'o | d1ef5c3 | 2001-07-20 12:35:11 -0400 | [diff] [blame] | 842 | |
| 843 | Speed up the check of an ext3 filesystems by avoiding a needless flush |
| 844 | of all of the superblock and block group descriptors. |
| 845 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 846 | Speed up creating an internal journal using tune2fs in the case where |
| 847 | the filesystem has a lot blocks already allocated. |
| 848 | |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 849 | Tune2fs has been fixed to make sure that only error messages go to |
| 850 | stderr, and normal message go to stdout. (Addresses Debian bug #108555) |
| 851 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 852 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 853 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 854 | |
Theodore Ts'o | d1ef5c3 | 2001-07-20 12:35:11 -0400 | [diff] [blame] | 855 | Add support in fsck for the filesystem type "auto". |
| 856 | |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 857 | Fsck -A will not try to interpret device names for filesystems which |
| 858 | have a pass number is 0. (Addresses Debian bug #106696). |
| 859 | |
| 860 | Fsck prints a warning message if now valid filesystems are passed to |
| 861 | it. (Addresses Debian Bug #107458.) |
| 862 | |
Theodore Ts'o | 9249d98 | 2001-07-20 18:14:10 -0400 | [diff] [blame] | 863 | E2fsck now gives an explicit warning if there filesystem still has |
| 864 | errors at the end of the run. (Addresses Debian bug #104502) |
| 865 | |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 866 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 867 | reflects an error. E2fsck will also not run the orphan list if the |
| 868 | filesystem contains errors, since the orphan list might be corrupted. |
Theodore Ts'o | d494bba | 2001-08-09 06:14:42 -0400 | [diff] [blame] | 869 | |
| 870 | E2fsck now prints the number of large files when given the -v option. |
| 871 | |
| 872 | Fixed minor memory leaks in e2fsck. |
Theodore Ts'o | bf16d10 | 2001-07-27 22:20:06 -0400 | [diff] [blame] | 873 | |
Theodore Ts'o | c4ac9e1 | 2001-08-15 21:02:23 -0400 | [diff] [blame] | 874 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |

Theodore Ts'o | 19d6b54 | 2001-06-23 00:13:09 -0400 | [diff] [blame] | 877 | E2fsprogs 1.22 (June 22, 2001) |
| 878 | ============================== |
| 879 | |
| 880 | Fixed a bug in e2fsck's handling of orphan inodes which are special |
| 881 | files (i.e., block/character device files, named FIFO's, etc.). |
| 882 | |
| 883 | Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused |
| 884 | tune2fs to fail at adding a journal to a mounted filesystem. |
| 885 | |
| 886 | Fixed a few big-endian bugs in e2fsprogs |
| 887 | * The directory block functions were accidentally reporting |
| 888 | some directories as corrupted when they weren't. |
| 889 | * If e2fsprogs is compiled --disable-swapfs, the C language |
| 890 | equivalents weren't being included for big-endian platforms. |
| 891 | (Fixes Debian bug #101686). |
| 892 | |
| 893 | Fixed a Hurd compilation problem. (Addresses Debian bug #101361) |
| 894 | |
| 895 | Programmer's notes: |
| 896 | ------------------- |
| 897 | |
| 898 | Use platform independent method of defining the BLKFLSBUF and FDFLUSH |
| 899 | ioctls, and allow them to be defined for non-i386 platforms. |
| 900 | |
| 901 | The uuid.h header file is now protected against multiple inclusions. |
| 902 | |
| 903 | E2fsprogs is now being developed using BitKeeper. Changed the test |
| 904 | scripts to deal with BK's stripping CR characgters from text files, |
| 905 | and changed the top-level Makefile.in to avoid including BitKeeper |
| 906 | files when generating the source tarball. |
| 907 | |
| 908 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 909 | E2fsprogs 1.21 (June 15, 2001) |
| 910 | ============================== |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 911 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 912 | Added new configure flags which allow a subset e2fsprogs to be built; |
| 913 | this is most useful for boot floopies, since the resulting shared |
| 914 | libraries and programs are slimmed down by removing features that |
| 915 | aren't necessary for a boot floppy. The new flags that were added |
| 916 | are: --disable-swapfs, which removes support for byte swapping old |
| 917 | legacy PPC/68k filesystems, --disable-debugfs, which removes support |
| 918 | for debugfs from the libext2fs library, --disable-imager, which |
| 919 | removes support for the e2image program, and --disable-resizer, which |
| 920 | removes support for resize2fs. |
| 921 | |
| 922 | E2fsck now prints the number of mounts or days elapsed since the last |
| 923 | check when e2fsck is forced to check an otherwise clean filesystem. |
| 924 | |
| 925 | Tune2fs now prints an informative message about how often a filesystem |
| 926 | will be checked when adding a journal to the filesystem, to remind the |
| 927 | user that he/she may want to adjust those parameters using tune2fs |
| 928 | -c/-i. |
| 929 | |
| 930 | Worked around hurd brain-damage which causes e2fsck to sometimes |
| 931 | believe a filesystem is the root filesystem based on device numbers |
| 932 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 |
| 933 | violation). |
| 934 | |
| 935 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an |
| 936 | erroneous error with the -F option was specified. |
| 937 | |
| 938 | Fixed a ext3 recovery bug in the revoke handling; synchronized with |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 939 | ext3 0.7a. |
| 940 | |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 941 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
| 942 | with relatively uncommon edge cases: a directory with an indirect |
| 943 | block which is claimed by another file, and when the last inode in the |
| 944 | filesystem has blocks claimed by another file. |
| 945 | |
Theodore Ts'o | 5a9c036 | 2001-06-02 04:55:57 +0000 | [diff] [blame] | 946 | E2fsck now checks to see if the i_size field of a fast symlink is too |
| 947 | big, and offers to clear the symlink if so. |
| 948 | |
| 949 | E2fsck now checks to see if i_size_high of special files is non-zero, |
| 950 | and offers to clear i_size_high. |
| 951 | |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 952 | Fix e2fsck's handling of incompatible journal flags so that the user |
| 953 | has chance to abort, and then has the option to clear out the journal |
Theodore Ts'o | e333845 | 2001-06-14 07:11:33 +0000 | [diff] [blame] | 954 | entirely. (Addresses Debian bug #98527.) |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 955 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 956 | Fixed a bug in fsck which could cause it to core dump if a mix of |
| 957 | standard and non-standard device names are used in /etc/fstab. |
| 958 | (Debian bug #100559) |
| 959 | |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 960 | Fixed a bug in debugfs which caused read errors when copying a file to |
| 961 | not be noticed. |
| 962 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 963 | The debugfs set_super_value command can now modify the s_lastcheck field. |
| 964 | |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 965 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
| 966 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading |
| 967 | directories correctly because the change modified the layout of struct |
| 968 | dirent to be incompatible with the libe2p shared library. |
| 969 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 970 | Cleaned up the mke2fs manual page and included a discussion about why |
| 971 | it's good to periodically check the filesystem even when journaling is |
| 972 | enabled. |
| 973 | |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 974 | Programmer's notes: |
| 975 | ------------------- |
| 976 | |
| 977 | Fix general gcc -Wall complaints. |
| 978 | |
| 979 | The types needed by the ext2 header files are now provided by |
| 980 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. |
| 981 | |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 982 | Integers are now preferred to longs when trying to find a 32-bit type |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 983 | in ext2_types.h. Also, if linux/types.h has already been defined, |
| 984 | don't try to redefine the types. |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 985 | |
Theodore Ts'o | 767de09 | 2001-06-02 01:20:18 +0000 | [diff] [blame] | 986 | Fixed make depend script so that it automatically corrects the |
| 987 | pathname cleanups performed by make -M, so I don't have to fix them up |
| 988 | by hand. |
| 989 | |
| 990 | Fixed the d_loaddump test case to be more robust, and not depend on |
| 991 | bash'isms. |
| 992 | |
| 993 | Removed debugfs's dependence on pread(), which was accidentally |
| 994 | intrudced in e2fsprogs 1.20 |
| 995 | |
Theodore Ts'o | c05b552 | 2001-06-08 12:03:36 +0000 | [diff] [blame] | 996 | Fixed a performance bug in the libext2fs's icount routine; the size |
| 997 | estimate of the icount array was incorrectly being calculated. |
| 998 | |
Theodore Ts'o | b90b826 | 2001-06-15 22:54:34 +0000 | [diff] [blame] | 999 | Removed use of the badblocks compatibility functions in the e2fsprogs |
| 1000 | programs. |
| 1001 | |
| 1002 | Added paranoia code which protects against strange cases where /etc |
| 1003 | isn't on the root filesystem, or if /etc/mtab doesn't exist. |
| 1004 | |
| 1005 | The header file ext2_types.h is now installed. |
| 1006 | |
| 1007 | Autoconf is used to determine when we are on big-endian machines, |
| 1008 | instead of doing run-time tests, to save a few bytes of code. |
| 1009 | |
| 1010 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap |
| 1011 | functions are no longer inline functions, which saves space and |
| 1012 | doesn't really cost any real performance. |
| 1013 | |
| 1014 | The ext2fs library no longer depends on the e2p library. (What need |
| 1015 | there was of it --- namely, fsetflags, was coded in-line). |
| 1016 | |
| 1017 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even |
| 1018 | when the user is stupid and tries compiling the package using "make |
| 1019 | install" as root. |
| 1020 | |
| 1021 | Miscellaneous code cleanups: |
| 1022 | * Added missing files from Makefile.in's SRCS file, so that |
| 1023 | their dependencies would be properly calculated. |
| 1024 | * Removed redundant code |
| 1025 | * Fixed comments in code |
| 1026 | * Removed no-longer unneeded argsused #pragma. |

Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1031 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1032 | Add support for replaying the ext3 journal purely in user mode, |
| 1033 | including handling the orphaned inode list. Used code contributed by |
| 1034 | Andreas Dilger, with bug fixes and the orphaned inode handling done |
| 1035 | by Theodore Ts'o. |
| 1036 | |
| 1037 | The mke2fs and tune2fs programs can create or modify a filesystem to |
| 1038 | include an ext3 journal. Tune2fs also can be used to remove an ext3 |
| 1039 | journal from a filesystem. |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1040 | |
| 1041 | E2fsck will now check for the existence of a linked list of orphan |
| 1042 | inodes in the superblock, and clear those inodes before starting the |
| 1043 | rest of the filesystem check (but after the journal playback). |
| 1044 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1045 | E2fsck now validates the file descriptor passed to the -C option, |
| 1046 | which saves against the completion bar getting written to an |
| 1047 | unexpected location, such as the disk being checked. (Debian |
| 1048 | bug/wishlist #55220) |
| 1049 | |
| 1050 | E2fsck will now bump the filesystem revision number from zero to one |
| 1051 | if any of the compatibility bits are set. |
| 1052 | |
| 1053 | Fixed a bug where a badly corrupted directory on a big endian system |
| 1054 | could cause e2fsck to die with a bus error. The |
| 1055 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in |
| 1056 | the ext2 library now does alignment sanity checks on the rec_len field |
| 1057 | of the directory entry before using it. |
| 1058 | |
| 1059 | The ext2 library has been enhanced to make tune2fs safe to run on |
| 1060 | mounted filesystems. (Users could usually get away with using tune2fs |
| 1061 | on mounted filesystems before, but with the advent of ext3 and |
| 1062 | journaling, it became important to make tune2fs was *really* safe for |
| 1063 | use even when the filesystem being modified is mounted.) E2label is |
| 1064 | now implemented by tune2fs using an argv[0] dispatch, so that e2label |
| 1065 | is also now safe for use on mounted filesystems. |
| 1066 | |
| 1067 | Added a new program, e2image, which creates a backup of critical ext2 |
| 1068 | filesystem data structures. The generated image file can be examined |
| 1069 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use |
| 1070 | the image file to help recover very badly damaged filesystems. |
| 1071 | |
| 1072 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files |
| 1073 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being |
| 1074 | large file when deciding whether or not the filesystem has large files. |
| 1075 | |
| 1076 | Fixed lsattr and chattr so that they work correctly on large files. |
| 1077 | (Fixes Debian bug #72690.) |
| 1078 | |
| 1079 | Removed limitation in get_device_size() which imposed a one terrabyte |
| 1080 | filesystem limitation. (Most 2.2 kernels still have a signed int |
| 1081 | problem which cause 1 TB block device limitation. Fortunately, the |
| 1082 | kernel patches to fix this are much easier than fixing the 2TB |
| 1083 | limitation in the kernel. :-) |
| 1084 | |
| 1085 | A max_mount_count of zero is now treated as if no mount count were |
| 1086 | set. (Previously, no mount count was indicated by using -1, and a |
| 1087 | mount count of zero caused e2fsck to always be run.) |
| 1088 | |
Theodore Ts'o | 7764856 | 2001-05-14 13:04:44 +0000 | [diff] [blame] | 1089 | Mke2fs supports two new filesystem types largefile and largefile4. |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1090 | |
| 1091 | Mke2fs now adds some randomness in s_max_mount_count so that multiple |
| 1092 | filesystems won't be all checked at the same time under normal |
| 1093 | operations. |
| 1094 | |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1095 | Fixed bug in the progress bar printing code which could cause e2fsck |
| 1096 | to core dump on an illegal filesystem. |
| 1097 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1098 | Fixed bug in fsck which could allow more than one instance of e2fsck |
| 1099 | to be printing a progress bar. (Debian bug #65267) |
| 1100 | |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1101 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
| 1102 | compiled into the kernel and not mounted. If the pathnames in |
| 1103 | /proc/partitions are incorrect, fsck will search /dev for the correct |
| 1104 | device (using the new ext2fs_find_block_device library function). |
| 1105 | Fsck now also checks the RAID devices first so that they are properly |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1106 | found when they are in use. Support has also been added to support |
| 1107 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) |
| 1108 | |
| 1109 | Fixed a bug in fsck which caused it not deal properly with 16 |
| 1110 | byte long filesystem labels. |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1111 | |
Theodore Ts'o | 5a009bb | 2001-05-21 05:27:45 +0000 | [diff] [blame] | 1112 | Fsck's -t option has been made a lot more flexible. The semantics for |
| 1113 | what happens if a comma-separated list to fsck has been regularized, |
| 1114 | and it is now possible to filter what filesystems will get checked |
| 1115 | based what is in the filesystem's fstab entry's option field. (Debian |
| 1116 | bug #89483.) |
| 1117 | |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1118 | The dumpe2fs program can now print out the group description |
| 1119 | information in hex, and also prints the location of the superblock and |
| 1120 | block group descriptor for those block groups that have them. |
| 1121 | |
| 1122 | Mke2fs now clears the ext2 superblock before it starts creating a |
| 1123 | filesystem, so that the superblock magic number is only written if the |
| 1124 | filesystem creation process successfully completes. |
| 1125 | |
| 1126 | The debugfs program's stat command now pretty-prints the blocks used |
| 1127 | by an inode so that it's more compact and informative. |
| 1128 | |
| 1129 | The debugfs stats command now uses the same libe2p code (which is used |
| 1130 | by dumpe2fs) to print the superblock header information. This is more |
| 1131 | complete, and it avoids a bit of code duplication. |
| 1132 | |
| 1133 | Added a new debugfs command, set_super_value (ssv) which allows the |
| 1134 | user to set arbitrary superblock fields. |
| 1135 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1136 | Debugfs was extended to support inode numbers in hex (by prefixing |
| 1137 | them with 0x), and so that modify_inode can set the inode generation |
| 1138 | number. Also, there is now a new function command called logdump |
| 1139 | which will dump an ext3 journal. |
| 1140 | |
| 1141 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill |
| 1142 | debugfs. |
| 1143 | |
| 1144 | Debugfs's dump command now stops immediately upon reporting a disk |
| 1145 | read error. (Fixed a bug in ext2fs_file_read library routine which |
| 1146 | caused debugfs not to stop.) (Debian bug #79163) |
| 1147 | |
| 1148 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is |
| 1149 | checked before /etc/mtab is used, since /proc/mounts is more likely to |
| 1150 | be accurate. |
| 1151 | |
| 1152 | Added portability fixes for Solaris and Linux/ia64. |
| 1153 | |
| 1154 | Various manual pages were clarified and cleaned up. (Fixed debian |
| 1155 | bugs #63442, #67446, and #87216) |
| 1156 | |

| 1158 | Programmer's notes: |
| 1159 | ------------------- |
| 1160 | |
| 1161 | The e2fsck message printer now supports %Iu and %Ig, which will print |
| 1162 | out the inode's user and group owners, respectively. |
| 1163 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1164 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
| 1165 | that no longer dependent on the system having the correct version of |
| 1166 | the kernel header files. |
| 1167 | |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1168 | Added a new function to libext2, ext2fs_find_block_device(), which |
| 1169 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a |
| 1170 | device given its device number. |
| 1171 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1172 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
| 1173 | all of the places which might try to use the BLKFLSBUF or FDFLUSH |
| 1174 | ioctls (and usually failing to define them since the system header |
| 1175 | files don't usually do this for us, and we're trying to avoid usage of |
| 1176 | kernel include files now). |
| 1177 | |
Theodore Ts'o | 5570a65 | 2000-08-21 01:23:39 +0000 | [diff] [blame] | 1178 | Added new utility programs in tests/progs: random_exercise and |
| 1179 | hold_inode. They aren't built by default; they're useful for |
| 1180 | exercising ext3 filesystem code. |
| 1181 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1182 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
| 1183 | the filesystem close functions to only update the superblock, and to |
| 1184 | not touch the block group descriptors. Needed by tune2fs when |
| 1185 | modifying a mounted filesystem. |
| 1186 | |
| 1187 | Got rid of struct ext2fs_sb and replaced it with the standard struct |
| 1188 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break |
| 1189 | source (but not binary) compatibility of some users of the ext2 |
| 1190 | library. Those applications should just simply do a global search and |
Theodore Ts'o | 7d614e3 | 2001-06-13 23:49:05 +0000 | [diff] [blame] | 1191 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
| 1192 | the new header file <ext2fs/ext2_fs.h> which defines it. |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1193 | |
| 1194 | The ino_t type has been renamed ext2_ino_t to protect applications |
| 1195 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this |
| 1196 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an |
| 1197 | unexpected ABI change. |
| 1198 | |
| 1199 | The Makefiles have been reworked so that "make check" can be run from |
| 1200 | the top-level Makefile. |
| 1201 | |
| 1202 | Fix general gcc -Wall complaints and removed dead code. |
| 1203 | |
| 1204 | Remove use of NOARGS, because we assume everyone does ANSI C these |
| 1205 | days. |
| 1206 | |
| 1207 | Added build-rpm script from sct. |
| 1208 | |
| 1209 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added |
| 1210 | to support e2image. |
| 1211 | |
| 1212 | New function ext2fs_flush_icache which must be called if the |
| 1213 | application program modifies the inode table blocks without going |
| 1214 | through ext2fs_write_inode() interface. |
| 1215 | |
| 1216 | New ext2fs_check_mount_point() function, which will return the mount |
| 1217 | point of a device if mounted. |
| 1218 | |
| 1219 | The io_channel abstraction now has an optional interface, |
| 1220 | io_channel_write_range, which allows specific byte ranges to be |
| 1221 | written. |
| 1222 | |
| 1223 | The unix_io IO channel now supports write-through caching, so that |
| 1224 | journal creation is more efficient. |
| 1225 | |
| 1226 | Added x86 assembly language routines to support byte swapping, to |
| 1227 | reduce executable size. |
| 1228 | |
| 1229 | Fixed bug in the utility program subst so that it's possible to |
| 1230 | replace a substitution variable with a zero-length string. |
| 1231 | |
| 1232 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had |
| 1233 | slipped into some of the problem number. |

Theodore Ts'o | b777e26 | 2000-07-27 01:39:23 +0000 | [diff] [blame] | 1235 | E2fsprogs 1.19 (July 13, 2000) |
| 1236 | ============================== |
Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 1237 | |
| 1238 | Release the resize2fs program since the timeout before it could |
Theodore Ts'o | 006ea71 | 2000-08-21 03:39:49 +0000 | [diff] [blame] | 1239 | be released under the GPL has finally expired. |
Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 1240 | |
| 1241 | Add experimental support needed for the ext2 compression patches. |
| 1242 | This requires compiling e2fsprogs with the --enable-compression flag |
| 1243 | to the configure script. |
| 1244 | |
| 1245 | Added ext3 journalling support. E2fsck will run the journal (if |
| 1246 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is |
| 1247 | installed as a symlink to e2fsck. Fsck has been taught about ext3, |
| 1248 | and treats it the same as ext2 in terms of the progress bar logic. |
| 1249 | Dumpe2fs will display the superblock journaling information if the |
| 1250 | filesystem has a journal. The ext2 library will now permit opening an |
| 1251 | ext3 filesystem with the recovery flag set. This is necessary for |
| 1252 | on-line dump's to work correctly, but there may be issues with this |
| 1253 | working well since ext3 is much less agressive about syncing blocks to |
| 1254 | the filesystem, since they're safe on the journal. |
| 1255 | |
| 1256 | Tune2fs and e2fsck have been changed to allow the mount_count check to |
| 1257 | be disabled by setting max_mount_count to -1. (This was already |
| 1258 | supported by the kernel.) |
| 1259 | |
| 1260 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities |
| 1261 | are used for ext3 as well. |
| 1262 | |
| 1263 | Added internationalization support for e2fsprogs; must be enabled |
| 1264 | by passing --enable-nls to configure. |
| 1265 | |
| 1266 | Always use the provided ext2fs header files to insulate ourselves from |
| 1267 | kernel version changes. Which include files are used by e2fsprogs |
| 1268 | have also been cleaned up to improve portability. |
| 1269 | |
| 1270 | Limit the number of times that e2fsck updates the progress bar so that |
| 1271 | people who are booting using a 9600 baud console don't get swampped by |
| 1272 | too many updates. |
| 1273 | |
| 1274 | Improved the loop detection algorithm in e2sck's pass #3 so that it is |
| 1275 | much, much faster for large filesystems with a large number of |
| 1276 | directories. |
| 1277 | |
| 1278 | The memory footprint for e2fsck is now slightly smaller than before. |
| 1279 | |
| 1280 | E2fsck now checks if special devices have a non-zero size, and offers |
| 1281 | to clear the size field if it finds such an inode. |
| 1282 | |
| 1283 | E2fsck now checks if special devices have the append-only flag set, |
| 1284 | and offers to clear the inode. |
| 1285 | |
| 1286 | E2fsck now properly handles some "should never fail" cases during a |
| 1287 | bitmap copy in pass5. |
| 1288 | |
| 1289 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. |
| 1290 | |
Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1291 | E2fsck now calculates the correct location of the backup superblock in |
| 1292 | the case of filesystem blocksizes > 1k. |
| 1293 | |
| 1294 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block |
| 1295 | which normally didn't cause problems under most filesystem parameters, |
| 1296 | but could cause a valid superblock to be rejected in extreme cases. |
| 1297 | Other checks for validating superblock values were made more |
| 1298 | stringent. |
| 1299 | |
Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 1300 | Added non-destructive write testing to the badblocks program, courtesy |
| 1301 | of David Beattie. The badblocks also now has an option to input the |
| 1302 | current set of bad blocks, so that known bad blocks are skipped to |
| 1303 | speed up the badblocks test. There is also a persistent rescan |
Theodore Ts'o | 006ea71 | 2000-08-21 03:39:49 +0000 | [diff] [blame] | 1304 | feature which causes badblocks to run until it has completed some |
| 1305 | number of passes without discovering any new bad blocks. |
Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 1306 | |
| 1307 | Badblocks now checks to see if the device is mounted and refuses to do |
| 1308 | the tests involving writing to the device if it is mounted. Also, |
| 1309 | badblocks now allows the number of blocks to be checked to be |
| 1310 | defaulted to the size of the partition. |
| 1311 | |
| 1312 | Fixed a bug in fsck which didn't allow non-root users to be able to |
| 1313 | check filesystems if there were any LABEL= or UUID= entries in |
| 1314 | /etc/fstab. |
| 1315 | |
| 1316 | The Hurd doesn't support the filetype filesystem feature. The mke2fs |
| 1317 | program now makes sure that for the Hurd, the filestype feature is |
| 1318 | turned off. E2fsck will check to see if the filetype feature is |
| 1319 | turned on for Hurd filesystems, and offer to turn off the feature. |
| 1320 | |
| 1321 | Mke2fs now has a safety check to make sure the number of blocks do not |
| 1322 | exceed 32 bits even on a 64 bit platform. |
| 1323 | |
| 1324 | Really fixed a bug in fsck to allow "fsck -As" to run interactive |
| 1325 | fsck's. (For those people who like to do interactive fsck's in the |
| 1326 | /etc/rc scripts!?!) |
| 1327 | |
| 1328 | Debugfs has a few new features: the rdump command, which will do a |
| 1329 | recursive dump of a directory and all of its contents, and the lcd |
| 1330 | command which does a local chdir (much like the ftp command of the |
| 1331 | same name). In addition, the debugfs program and the open_filesystem |
| 1332 | command now takes three new options: -b and -s, which allows the |
| 1333 | blocksize and superblock location to be specified, and the -c option |
| 1334 | which is used in catastrophic situations where the block group |
| 1335 | descriptors are corrupt. If the -c option is specified, debugfs will |
| 1336 | skip trying to read in the block and inode bitmaps. |
| 1337 | |
| 1338 | Debufs's lsdel command was fixed to handle bad blocks in the inode |
| 1339 | table. |
| 1340 | |
| 1341 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use |
| 1342 | 4 digit years. |
| 1343 | |
| 1344 | General improvements in error messages |
| 1345 | |
| 1346 | - Mke2fs prints a sane error message if the partition size is zero |
| 1347 | (usually because the partition table wasn't reread by the |
| 1348 | kernel due to the partition being busy), instead of "invalid |
| 1349 | argument passed to ext2 library while initializing superblock". |
| 1350 | |
| 1351 | - Fsck now prints more self-explanatory message if an invalid UUID= |
| 1352 | or LABEL= specification is passed to it. |
| 1353 | |
| 1354 | UUID library changed to use the LGPL. |
| 1355 | |
| 1356 | Fixed a bug in the UUID library where very rapid calls to the |
| 1357 | time-based UUID generator could cause duplicate UUID's to be returned. |
| 1358 | This was not a problem for e2fsprogs, but it could be a problem for |
| 1359 | other users of the library. |
| 1360 | |
| 1361 | Make the UUID library more robust in the face of missing or an |
| 1362 | improper /dev/urandom or /dev/random files. |
| 1363 | |
| 1364 | Added some random portability fixes for Solaris. |
| 1365 | |
| 1366 | Some minor man page updates. |
| 1367 | |
| 1368 | Fixed a memory leak in the ss library. |
| 1369 | |
| 1370 | |
| 1371 | Programmer's notes: |
| 1372 | ------------------- |
| 1373 | |
| 1374 | We now try to use lseek64 and open64 from the LFS if possible. |
| 1375 | |
| 1376 | The 3rd parameter in e2p's print_flags is now a flags word, instead of |
| 1377 | a boolean option. |
| 1378 | |
| 1379 | The mark and unmark bitmap functions now return the previous state of |
| 1380 | the bit that was being changed, which is useful for some speed |
| 1381 | optimizations. |
| 1382 | |
| 1383 | The following functions have been added to enhance the badblocks list |
| 1384 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and |
| 1385 | ext2fs_badblocks_equal. |
| 1386 | |
| 1387 | The ext2 header files now have the latest journalling fields to the |
| 1388 | superblock. |
| 1389 | |
| 1390 | The ext2fs_mkdir function in libext2fs now properly backs out of error |
| 1391 | conditions robustly. |
| 1392 | |
| 1393 | Cleaned up makefiles: |
| 1394 | - to cleanly compile with the -j flag. |
| 1395 | - so distclean removes all generated files. |
| 1396 | - so in case of an error while installing header files, the make aborts. |
| 1397 | |
| 1398 | Fix test_script so that it works correctly when compiling in the |
| 1399 | source directory. |

Theodore Ts'o | 31d1d0c | 2001-05-11 05:15:06 +0000 | [diff] [blame] | 1401 | The random UUID generation routine has been made slightly better in |
| 1402 | the case where /dev/random doesn't exist. (Use of randomly-based UUID |
| 1403 | is still not recommended if /dev/random doesn't exist, however; it's |
| 1404 | better to use the time/ethernet MAC address UUID in this case.) |
Theodore Ts'o | ab14676 | 2000-07-07 04:37:35 +0000 | [diff] [blame] | 1405 | |
| 1406 | Clean up the build process so it's more friendly in case of missing |
| 1407 | directories. |
| 1408 | |
| 1409 | The ext2fs header file can now be #include'd into C++ programs. |
| 1410 | |
| 1411 | The e2p.h header file is now installed. |
| 1412 | |
| 1413 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. |

Theodore Ts'o | 24ded09 | 1999-11-10 15:56:16 +0000 | [diff] [blame] | 1417 | E2fsprogs 1.18 (November 10, 1999) |
| 1418 | ================================== |
| 1419 | |
| 1420 | Fix a core dumping bug in e2fsck if an imagic inode is present or |
| 1421 | (more rarely) if the filesystem is badly corrupted enough that e2fsck |
| 1422 | has to restart pass 1 processing. E2fsck now closes the filesystem |
| 1423 | before freeing a large number of its data structures, so in the case |
| 1424 | of future memory faults, at least the fixed filesystem will be fully |
| 1425 | written out. |
| 1426 | |
| 1427 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an |
| 1428 | imagic inode, it will offer to clear the imagic flag. |
| 1429 | |
| 1430 | E2fsck will now offer to clear the immutable flag on special files |
| 1431 | (device/socket/fifos) when running it in non-preen mode. |
| 1432 | |
| 1433 | E2fsck will now set the filetype when creating /lost+found, and when |
| 1434 | connected orphaned inodes to /lost+found. |
| 1435 | |
| 1436 | Debugfs's ncheck and icheck commands now handles the case where there |
| 1437 | are bad blocks in the inode table without bombing out. |
| 1438 | |
| 1439 | The badblocks list processing code has been made more efficiently for |
| 1440 | appending a large number of (ordered) badblocks to the badblocks list. |
| 1441 | |
| 1442 | Some minor man page updates. |
| 1443 | |
| 1444 | Fsck now allows interactive e2fsck's when using fsck -As (not a common |
| 1445 | mode, but some people like to do this in boot scripts for silly reasons). |
| 1446 | |
| 1447 | Programmer's notes: |
| 1448 | ------------------- |
| 1449 | |
| 1450 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet |
| 1451 | with the problem code convention. |
| 1452 | |
| 1453 | The badblocks list regression test program has been updated to work |
| 1454 | with previously made API name changes. |
| 1455 | |
| 1456 | The ext2fs_free() command now uses the new badblocks API to avoid |
| 1457 | using the compatibility layer. |
| 1458 | |
| 1459 | Added new regression test cases; the run_e2fsck test script now |
| 1460 | supports the ability for a test case to run a prepratory command |
| 1461 | before running e2fsck. |
| 1462 | |
Theodore Ts'o | 28e1194 | 1999-10-26 18:17:20 +0000 | [diff] [blame] | 1463 | E2fsprogs 1.17 (October 26, 1999) |
| 1464 | ================================= |
| 1465 | |
| 1466 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an |
| 1467 | infinite loop. |
| 1468 | |
| 1469 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, |
| 1470 | thus potentially causing problems if a binary UUID contained a NULL |
| 1471 | character. |
| 1472 | |
| 1473 | E2fsck now uses stricter checks for directory entries in pass 2: |
| 1474 | zero-length filenames are not allowed; neither are 8 byte long |
| 1475 | directory entries. |
| 1476 | |
| 1477 | The debugfs "dirty" command now clears the filesystem valid bit. |
| 1478 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk |
| 1479 | bit in the in-core superblock image. The new functionality is more |
| 1480 | what the user expects, and is more useful.) |
| 1481 | |
| 1482 | Added a debugging hook to test parallel fsck; if the environment |
| 1483 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive |
| 1484 | will be checked in parallel when they normally would not be. |
| 1485 | |
| 1486 | Programmer's notes: |
| 1487 | ------------------- |
| 1488 | |
| 1489 | Fixed some #ifdef's for compilation under the Hurd OS. |
| 1490 | |
| 1491 | Fixed minor W2K compatibility problems. |
| 1492 | |
| 1493 | Fixed some miscellaneous GCC warnings. |
| 1494 | |
| 1495 | |
Theodore Ts'o | 8a31ffe | 1999-10-23 03:33:15 +0000 | [diff] [blame] | 1496 | E2fsprogs 1.16 (October 22, 1999) |
| 1497 | ================================= |
| 1498 | |
| 1499 | Fixed a race condition bug in fsck; when printing a progress bar, if |
| 1500 | checking multiple filesystems in parallel, it was possible for fsck to |
| 1501 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal |
| 1502 | handler, which would cause it to terminate with a signal 10. |
| 1503 | |
| 1504 | E2fsck now properly handles filesystems that have the |
| 1505 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a |
| 1506 | filesystem into using or not using FILETYPE feature. |
| 1507 | |
| 1508 | E2fsck now properly handles filesystems that have the IMAGIC feature |
| 1509 | turned on (this is used on Linux AFS servers). |
| 1510 | |
| 1511 | The mke2fs program now creates filesystems that have the filetype and |
| 1512 | sparse_superblock features enabled by default, unless it is run on a |
| 1513 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, |
| 1514 | so there is now a new flag -O which allows the user to specify with |
| 1515 | which features she would like to create the filesystem; "mke2fs -O |
| 1516 | none" will create a filesystsem compatible with 2.0 kernels. |
| 1517 | |
| 1518 | The tune2fs program now has a -O option which allows the user to set |
| 1519 | and reset "safe" filesystem features. Currently, the only ones which |
| 1520 | allows to be modified are the filetype and sparse_superblock features. |
| 1521 | Note setting or clearing either feature will require running e2fsck on |
| 1522 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature |
| 1523 | requires that there is enough free space on the filesystem for the |
| 1524 | extra superblocks which will be created by e2fsck.) |
| 1525 | |
| 1526 | Debugfs can now set and print filesystem features in the superblock |
| 1527 | using the "features" command. Dumpe2fs will print out the complete |
| 1528 | set of features when listing the superblock. |
| 1529 | |
| 1530 | Dumpe2fs has new options -f (force) and -h (header-only). |
| 1531 | |
| 1532 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead |
| 1533 | message to come up. This could happen when decrementing or |
| 1534 | incrementing a link count could result in an overflow. |
| 1535 | |
| 1536 | Fixed a bug in e2fsck where the block count on the lost+found |
| 1537 | directory would not be properly incremented when the directory was |
| 1538 | expanded to the point where an indirect block needed to be allocated. |
| 1539 | |
| 1540 | E2fsck now makes some additional sanity checks on the superblock to |
| 1541 | avoid crashing or giving a memory allocation error if some of the |
| 1542 | values in the superblock are unresonable (but the superblock otherwise |
| 1543 | looks valid). |
| 1544 | |
| 1545 | Fixed a bug in e2fsck where a very badly corrupted filesystem might |
| 1546 | require two passes to completely fix the filesystem. This happened if |
| 1547 | an inode claimed blocks that was part of the filesystem metadata |
| 1548 | (typically, when garbage was written into an inode table or indirect |
| 1549 | block, since this kind of filesystem corruption normally doesn't |
| 1550 | happen otherwise). |
| 1551 | |
| 1552 | On the Alpha, glibc declares st_flags although it isn't actually used; |
| 1553 | the configure script was improved to detect this case so that |
| 1554 | e2fsprogs can avoid using the non-functional stat field. |
| 1555 | |
| 1556 | The manual pages were updated to use a more consistent formatting |
| 1557 | style consistent with standard Unix man pages. Mke2fs's man page |
| 1558 | added documentation for a few previously undocumented options. |
| 1559 | |
| 1560 | Fixed minor display bugs in tune2fs and mke2fs. |
| 1561 | |
| 1562 | Programmer's notes: |
| 1563 | ------------------- |
| 1564 | |
| 1565 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). |
| 1566 | |
| 1567 | Added features to parse and print feature strings into the e2p library. |
| 1568 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). |
| 1569 | |
| 1570 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories |
| 1571 | whose directory entries contain proper filetype information if the |
| 1572 | filesystem supports it. |
| 1573 | |
| 1574 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass |
| 1575 | the directory entry filetype information. This is used to set the |
| 1576 | directory entry filetype information if the filesystem supports it. |
| 1577 | |
| 1578 | Fixed a bug in ext2fs_expand_dir() where the block count in a |
| 1579 | directory's inode would not be properly incremented when the directory |
| 1580 | was expanded to the point where an indirect block needed to be |
| 1581 | allocated. |
| 1582 | |

Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 1585 | ============================== |
Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 1586 | |
| 1587 | Add configuration checks so that e2fsprogs will compile cleanly on |
| 1588 | Linux 2.3 kernels that have renamed i_version to i_generation. |
| 1589 | |
Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 1590 | E2fsck now prints a progress/completion bar (and not just a simple |
| 1591 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 |
| 1592 | signal. Fsck will automatically manage the (potentially muliple) |
| 1593 | e2fsck processes to print completion bars if it is given a -C option, |
| 1594 | with the right thing happening if multiple filesystems are being |
| 1595 | checked in parallel. |
| 1596 | |
| 1597 | Mke2fs now has better automatic hueristics to determine the filesystem |
| 1598 | parameters to be used for a particular filesystem. Added a new option |
| 1599 | -T which allows the user to specify how the filesystem is to be used, |
| 1600 | which helps mke2fs do a better job selecting the filesystem parameters. |
| 1601 | |
Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 1602 | Mke2fs now creates revision 1 filesystems by default, and with the |
| 1603 | sparse superblock feature enabled. The sparse superblock feature is |
Theodore Ts'o | 8a31ffe | 1999-10-23 03:33:15 +0000 | [diff] [blame] | 1604 | not understood by Linux 2.0 kernels, so they will only allow read-only |
| 1605 | mounts of filesystems with this sparse superblocks. |
Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 1606 | |
Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 1607 | Fix bug where if /dev/null couldn't be opened (should never happen), |
| 1608 | e2fsck would hang in a tight loop. |
| 1609 | |
| 1610 | Make e2fsck handle the case where /lost+found isn't a directory. |
| 1611 | |
| 1612 | E2fsck now uses mallinfo if it exists to get accurate statistics about |
| 1613 | its memory usage. |
| 1614 | |
| 1615 | Fix bug in e2fsck where it wouldn't check to see if a disconnected |
| 1616 | inode had any problems before connecting it to /lost+found. |
| 1617 | |
| 1618 | Add check to e2fsck so it makes sure that total number of inodes in |
| 1619 | the filesystem is a sane number. |
| 1620 | |
| 1621 | Fix fencepost error when clearing an the end of the block bitmap which |
| 1622 | caused the last block in the bitmap not to get cleared. |
| 1623 | |
| 1624 | Cleaned up a number of messages in e2fsck: |
| 1625 | * The message "Group's #'s copy of the group descriptor..." |
| 1626 | was fixed so that the correct number would be displayed. |
| 1627 | * Added missing space in the "disk write-protected" error messsage |
| 1628 | * Cleaned up the error message printed when a non-interactive |
| 1629 | e2fsck needs to abort a check because the filesystem |
| 1630 | appears to be mounted. |
| 1631 | |
| 1632 | Added a new command-line utility, uuidgen, which will create and print |
| 1633 | a UUID. |
| 1634 | |
| 1635 | Make debugfs's icheck command more robust by checking to make sure an |
| 1636 | inode has valid blocks before interarting over the inode's blocks. |
| 1637 | |
| 1638 | UUID generation now uses a random-based scheme whenever possible to |
| 1639 | prevent potential privacy problems. |
| 1640 | |
| 1641 | Man pages for all of the UUID functions in the lirbary were added. |
| 1642 | |
| 1643 | Fixed bug in fsck so it won't coredump if a filesystem not in |
| 1644 | /etc/fstab is given to it. |
| 1645 | |
| 1646 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab |
| 1647 | that most of the other mount utilities understands. |
| 1648 | |
| 1649 | Mke2fs will make a filesystem even if it appears mounted if the force |
| 1650 | option is given. |
| 1651 | |
| 1652 | Dumpe2fs has new command-line options which allow a filesystem expert |
| 1653 | to specify the superblock and blocksize when opening a filesystem. |
| 1654 | This is mainly useful when examining the remains of a toasted |
| 1655 | filesystem. |
| 1656 | |
| 1657 | The badblocks program has been updated to display correctly on disks |
| 1658 | with large block numbers. |
| 1659 | |
Theodore Ts'o | e2a99be | 1999-07-19 15:48:08 +0000 | [diff] [blame] | 1660 | The badblocks program no longer gives spurious errors when errors |
| 1661 | occur on non-block boundaries, which is common if the blocksize is |
| 1662 | larger than 1k. |
| 1663 | |
Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 1664 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
| 1665 | MKE2FS_SYNC environment variable is set. This is to work around a VM |
| 1666 | bug in the 2.0 kernel. I've heard a report that a RAID user was able |
Theodore Ts'o | a39f3ef | 1999-07-20 02:02:40 +0000 | [diff] [blame] | 1667 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
| 1668 | needed for most Linux 2.2 users. |
Theodore Ts'o | 6d53db3 | 1999-07-03 20:52:21 +0000 | [diff] [blame] | 1669 | |
| 1670 | Fixed miscellaneous documentation and man pages. |
| 1671 | |
| 1672 | Programmer's notes: |
| 1673 | ------------------- |
| 1674 | |
| 1675 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which |
| 1676 | in e2fsck's pass1.c really should have been static. |
| 1677 | |
| 1678 | The return value of the uuid_compare() function was changed to make it |
| 1679 | match with the convetions used by strcmp, memcmp, and Paul Leach's |
| 1680 | UUID sample document. |
| 1681 | |
| 1682 | The "make depend" process has now been made more automated; it now |
| 1683 | automatically word-wraps the dependencies, and only replaces source |
| 1684 | Makefile.in if there has been a change in the dependencies. Also, a |
| 1685 | top-level "make depend" now recurses through all the subdirectories |
| 1686 | automatically. |
| 1687 | |
| 1688 | The Makefile in .../util has been changed so that subst is built using |
| 1689 | the native C compiler during a cross-compilation, since the subst |
| 1690 | program is only used during the build process. Also add an explicit |
| 1691 | rule to build util/subst by cd'ing to the correct directory and |
| 1692 | running Makefile. |
| 1693 | |
| 1694 | The man directories are defined in terms mandir, so that the configure |
| 1695 | script can override the location of the manual pages. |
| 1696 | |
| 1697 | The config files have been updated to recognize new machine types for |
| 1698 | both the i386 and alpha families. |
| 1699 | |
| 1700 | Fsck has been modified so that it will accurately create an |
| 1701 | fsck_instance even when the noexecute flag is set. This allows for |
| 1702 | accurate debugging of the fsck pass structure. Also, when the verbose |
| 1703 | flag is given twice, fsck will print debugging information about when |
| 1704 | fsck is waiting for jobs to finish. |
| 1705 | |
| 1706 | |
Theodore Ts'o | 14790ed | 1999-01-12 23:32:52 +0000 | [diff] [blame] | 1707 | E2fsprogs 1.14 (January 9, 1999) |
| 1708 | ================================ |
| 1709 | |
| 1710 | Fix the fstab parsing code so that it can handle blank lines and |
| 1711 | comment characters. Also, missing pass numbers need to be treated as |
| 1712 | zero. |
| 1713 | |
| 1714 | Fixed a bug in e2fsck where under some circumstances (when e2fsck |
| 1715 | needs to restart processing after fixing an egregious inconsistency) |
| 1716 | it would try to access already freed memory. |
| 1717 | |
| 1718 | E2fsck now prints non-printable characters in directory entries and |
| 1719 | pathnames using '^' and 'M-' notation. |
| 1720 | |
| 1721 | Fixed chattr so that it will ignore symbolic links when doing |
| 1722 | recursive descent traversals. For both chattr and lsattr, no longer |
| 1723 | print the version string unless the -V option is given. |
| 1724 | |
| 1725 | Allow the system administrator to directly specify the number of |
| 1726 | inodes desired in the filesystem, for some special cases where this is |
| 1727 | necessary. |
| 1728 | |
| 1729 | Fix portability problems so that e2fsprogs can be compiled under Linux |
| 1730 | 1.2 systems and Solaris systems. |
| 1731 | |
| 1732 | Update the config.guess file with a more recent version that will |
| 1733 | identify newer Linux platforms. |
| 1734 | |
| 1735 | Programmer's notes |
| 1736 | ------------------ |
| 1737 | |
| 1738 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if |
| 1739 | an inode number of zero is passed to them. |
| 1740 | |
Theodore Ts'o | 556ad13 | 1998-12-19 08:10:58 +0000 | [diff] [blame] | 1741 | E2fsprogs 1.13 (December 15, 1998) |
| 1742 | ================================== |
| 1743 | |
| 1744 | Fixed a bug in debugfs where an error messages weren't getting printed |
| 1745 | when the ext2 library routines to read inodes returned errors in the |
| 1746 | stat, cmri and rm commands. |
| 1747 | |
| 1748 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is |
| 1749 | provided, it won't create an inode table smaller than the minimum |
| 1750 | number of inodes required for a proper ext2 filesystem. |
| 1751 | |
| 1752 | Fsck now parses the /etc/fstab file directly (instead of using |
| 1753 | getmntent()), so that it can distinguish between a missing pass number |
| 1754 | field and pass number field of zero. This caused problems for |
| 1755 | diskless workstations where all of the filesystems in /etc/fstab have |
| 1756 | an explicit pass number of zero, and fsck could not distinguish this |
| 1757 | from a /etc/fstab file with missing pass numbers. |
| 1758 | |
| 1759 | E2fsck will create a /lost+found directory if there isn't one in the |
| 1760 | filesystem, since it's safer to create the lost+found directory before |
| 1761 | it's needed. |
| 1762 | |
| 1763 | Fixed e2fsck so that it would detect bogus immutable inodes which |
| 1764 | happen to be sockets and FIFO files, and offer to clear them. |
| 1765 | |
| 1766 | If a filesystem has multiple reasons why it needs to be checked, and |
| 1767 | one of the reasons is that it is uncleanly mounted, e2fsck will print |
| 1768 | that as the reason why the filesystem is being checked. |
| 1769 | |
| 1770 | Cleaned up the output routines of mke2fs so that it doesn't overflow |
| 1771 | an 80 column display when formating really big filesystems. |
| 1772 | |
| 1773 | Added a sanity check to e2fsck to make sure that file descriptors 0, |
| 1774 | 1, 2 are open before opening the hard disk. This avoids a problem |
| 1775 | where a broken program might exec e2fsck with those file descriptors |
| 1776 | closed, which would cause disastrous results if the kernel returns a |
| 1777 | file descriptor for the block device which is also used by FILE * |
| 1778 | stdout. |
| 1779 | |
| 1780 | Fixed up the e2fsck progress reporting functions so that the values |
| 1781 | reliably reach 100% at the completion of all of the e2fsck passes. |
| 1782 | |
| 1783 | Fixed minor documentation bugs in man pages and usage messages. |
| 1784 | |
| 1785 | Programmer's notes: |
| 1786 | ------------------- |
| 1787 | |
| 1788 | Fixed a number of lint warnings in the ext2fs library and potential |
| 1789 | portability problems from other OS's header files that might define |
| 1790 | CPP macros for names like "max" and "min". |
| 1791 | |
| 1792 | ext2fs_badblocks_list_add() has been made more efficient when it needs |
| 1793 | to grow the bad blocks list. |
| 1794 | |
| 1795 | Fixed a bug in e2fsck which caused it to dereference a freed pointer |
| 1796 | just before exiting. |
| 1797 | |
| 1798 | Fixed the substition process for generating the mk_cmds and compile_et |
| 1799 | scripts so that they will work outside of the build tree. |
| 1800 | |
| 1801 | Add sanity check to e2fsck so that if an internal routine |
| 1802 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer |
| 1803 | and causing a core dump. This should never happen, but... |

Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 1806 | ================================== |
| 1807 | |
| 1808 | E2fsprogs now works with glibc (at least with the version shipped wtih |
| 1809 | RedHat 5.0). The ext2fs_llseek() function should now work even with |
| 1810 | i386 ELF shared libraries and if llseek() is not present. We also |
| 1811 | explicitly do a configure test to see if (a) llseek is in libc, and |
| 1812 | (b) if llseek is declared in the system header files. (See standard |
| 1813 | complaints about libc developers don't understand the concept of |
| 1814 | compatibility with previous versions of libc.) |
| 1815 | |
Theodore Ts'o | c9833a6 | 1998-07-05 19:37:53 +0000 | [diff] [blame] | 1816 | The ext2fs library now writes out the block group number in each of |
| 1817 | the superblock copies. This makes it easier to automatically |
| 1818 | determine the starting block group of the filesystem when the block |
| 1819 | group information is trashed. |
| 1820 | |
| 1821 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, |
Theodore Ts'o | 101c84f | 1998-03-24 16:27:11 +0000 | [diff] [blame] | 1822 | which means that e2fsprogs will ignore the high 8 bits of the |
| 1823 | directory entry's name_len field, so that it can be used for other |
| 1824 | purposes. |
| 1825 | |
| 1826 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. |
| 1827 | E2fsprogs will now support filesystems with 64-bit sized files. |
| 1828 | |
| 1829 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. |
| 1830 | |
Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 1831 | Added new program "e2label", contributed by Andries Brouwer. E2label |
| 1832 | provides an easy-to-use interface to modify the filesystem label. |
| 1833 | |
Theodore Ts'o | a4b2d3c | 1998-04-03 16:12:25 +0000 | [diff] [blame] | 1834 | Fixed bug so that lsattr -v works instead of producing a core dump. |
| 1835 | |
Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 1836 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
| 1837 | backup blocks are printed (not just the first one). |
Theodore Ts'o | a4b2d3c | 1998-04-03 16:12:25 +0000 | [diff] [blame] | 1838 | |
| 1839 | Mke2fs will check the size of the device, and if the user specifies a |
| 1840 | filesystem size larger than the apparent size of the device it will |
| 1841 | print a warning message and ask if the user wants to proceed. |
| 1842 | |
Theodore Ts'o | c9833a6 | 1998-07-05 19:37:53 +0000 | [diff] [blame] | 1843 | E2fsck has a new option -C, which sends completion information to the |
| 1844 | specified file descriptor. For the most part, this is intended for |
| 1845 | programs to use, although -C 0 will print a spinning character to the |
| 1846 | stdout device, which may be useful for users who want to see something |
| 1847 | happening while e2fsck goes about its business. |
| 1848 | |
Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 1849 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
| 1850 | expand the /lost+found directory, and sometimes the bitmaps haven't |
| 1851 | been merged in. Also fixed a related bug where ext2fs_write_dir_block |
| 1852 | was used to write out a non-directory block. (Which would be bad on a |
| 1853 | non-Intel platform with byte swapping going on.) |
| 1854 | |
| 1855 | Fixed bug in e2fsck where it would print a "programming error" message |
| 1856 | instead of correctly identifying where a bad block was in used when |
| 1857 | the bad block was in a non-primary superblock or block group |
| 1858 | descriptor. Also fixed a related bug when sparse superblocks are in |
| 1859 | use and there is a bad block where a superblock or block group |
| 1860 | descriptor would have been in a group that doesn't include a |
| 1861 | superblock. |
| 1862 | |
| 1863 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if |
| 1864 | the block group descriptor table is corrupt, it was possible to try to |
| 1865 | allocate a huge array, fail, and then abort e2fsck. |
| 1866 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, |
| 1867 | and subsitutes reasonable values if the descriptors are obviously bogus. |
| 1868 | |
| 1869 | If e2fsck finds a device file which has the immutable flag set and the |
| 1870 | i_blocks beyond the normal device number are non-zero, e2fsck will |
| 1871 | offer to remove it, since it's probably caused by garbage in the inode |
| 1872 | table. |
| 1873 | |
| 1874 | When opening a filesystem, e2fsck specially checks for the EROFS error |
| 1875 | code, and prints a specific error message to the user which is more |
| 1876 | user friendly. |
| 1877 | |
| 1878 | If the filesystem revision is too high, change the e2fsck to print |
| 1879 | that this is either because e2fsck is out of date, or because the |
| 1880 | superblock is corrupt. |
| 1881 | |
| 1882 | E2fsck now checks for directories that have duplicate '.' and '..' |
| 1883 | entries, and fixes this corruption. |
| 1884 | |
| 1885 | E2fsck no longer forces a sync of the filesystem (with attendant sleep |
| 1886 | calls) at all times. The ext2fs_flush() function now performs a sync |
| 1887 | only if it needed to write data blocks to disk. |
| 1888 | |
| 1889 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where |
| 1890 | certain errors would not be properly reported. |
| 1891 | |
| 1892 | Updated and expanded a few points in the man pages which users |
| 1893 | complained wheren't explicit enough. |
| 1894 | |
| 1895 | Added special case byte-swapping code if compiling on the PowerPC, to |
| 1896 | accomodate the strange big-endian variant of the ext2 filesystem that |
| 1897 | was previously used on the PowerPC port. |
| 1898 | |
| 1899 | |
| 1900 | Programmer's notes: |
| 1901 | ------------------- |
| 1902 | |
| 1903 | Removed C++ keywords from the ext2fs libraries so that it could be |
| 1904 | compiled with C++. |
| 1905 | |
| 1906 | E2fsck's internal organization has now been massively reorganized so |
| 1907 | that pass*.c don't have any printf statements. Instead, all problems |
| 1908 | are reported through the fix_problem() abstraction interface. E2fsck |
| 1909 | has also been revamped so that it can be called as a library from a |
| 1910 | application. |
| 1911 | |
| 1912 | Added new fileio primitives in libext2fs for reading and writing |
| 1913 | files on an unmounted ext2 filesystem. This interface is now used by |
| 1914 | debugfs. |
| 1915 | |
| 1916 | Added a new libext2fs function for mapping logical block numbers of |
| 1917 | a file to a physical block number. |
| 1918 | |
| 1919 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates |
| 1920 | a block, zeros it, and updates the filesystem accounting records |
| 1921 | appropriately. |
| 1922 | |
| 1923 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which |
| 1924 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. |
| 1925 | |
| 1926 | The libext2fs functions now use a set of memory allocation wrapper |
| 1927 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, |
| 1928 | instead of malloc, free, and resize. This makes it easier for us to |
| 1929 | be ported to strange environments where malloc, et. al. aren't |
| 1930 | necessarily available. |
| 1931 | |
| 1932 | Change the libext2fs fucntion to return ext2-specific error codes |
| 1933 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using |
| 1934 | and depending on the existence of system error codes (such as EEXIST |
| 1935 | and ENOENT). |
| 1936 | |
| 1937 | Renamed io.h to ext2_io.h to avoid collision with other OS's header |
| 1938 | files. |
| 1939 | |
| 1940 | Add protection against ext2_io.h and ext2fs.h being included multiple |
| 1941 | times. |
| 1942 | |
| 1943 | The types used for memory lengths, etc. have been made more portable. |
| 1944 | In generla, the code has been made 16-bit safe. Added Mark |
| 1945 | Habersack's contributed DOS disk i/o routines. |
| 1946 | |
| 1947 | Miscellaneous portability fixes, including not depending on char's |
| 1948 | being signed. |
| 1949 | |
| 1950 | The io_channel structure has a new element, app_data, which is |
| 1951 | initialized by the ext2fs routines to contain a copy of the filesystem |
| 1952 | handle. |
| 1953 | |
| 1954 | ext2fs_check_directory()'s callback function may now return the error |
| 1955 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to |
| 1956 | really do the checking, despite the presence of the callback function. |
| 1957 | |

| 1960 | ============================== |
| 1961 | |
| 1962 | Fixed e2fsck to detect (previously ignored) conflicts between the |
| 1963 | superblock or block group descriptors and block bitmaps, inode |
| 1964 | bitmaps, and inode tables. |
| 1965 | |
| 1966 | Fixed bug in e2fsck so that when the message printed out when a block |
| 1967 | or inode bitmap conflicts with other data, it has the correct group |
| 1968 | number. |
| 1969 | |
| 1970 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed |
| 1971 | to badblocks. This meant that not all of the filesystem was being |
| 1972 | tested for bad blocks! |
| 1973 | |
| 1974 | Fixed an array boundary overrun case which cropped up in |
| 1975 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c |
| 1976 | -b 4096". |
| 1977 | |
| 1978 | Adjusted the number of columns printed by mke2fs when displaying the |
| 1979 | superblock backups to avoid running over 80 columns when making a |
Theodore Ts'o | 21d5385 | 1998-02-21 03:14:50 +0000 | [diff] [blame] | 1980 | really big filesystem. |
Theodore Ts'o | bc21007 | 1997-06-17 05:41:36 +0000 | [diff] [blame] | 1981 | |
| 1982 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, |
| 1983 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar |
| 1984 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). |
| 1985 | |
| 1986 | Programmer's notes: |
| 1987 | ------------------- |
| 1988 | |
| 1989 | Fixed install rule in lib/ss so that ss_err.h is actually getting |
| 1990 | installed. |
| 1991 | |
| 1992 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting |
| 1993 | bassed back to the caller. |
| 1994 | |
| 1995 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been |
| 1996 | setting the current inode number (which meant this function wasn't |
| 1997 | working at all). |
| 1998 | |
| 1999 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all |
| 2000 | blocks in the bitmap when increasing the size of the bitmap. |
| 2001 | |
| 2002 | Changed the initial number of blocks allocated by ext2fs_init_dblist() |
| 2003 | to be more realistic. |
| 2004 | |
| 2005 | Added a new function ext2fs_allocate_group_table, which sets up the |
| 2006 | group descriptor information (and allocates inode and block bitmaps, |
| 2007 | and inode tables for a particular group). The function was created by |
| 2008 | factoring out code form ext2fs_allocate_tables(). |
| 2009 | |
| 2010 | Added a new function ext2fs_move_blocks which takes a bitmap of the |
| 2011 | blocks to be moved, and moves them to another location on the |
| 2012 | boardboard. |
| 2013 | |
| 2014 | Make the unix_io channel's io_channel_flush implementation calls sync() |
| 2015 | to to flush the kernel buffers to disk. |
| 2016 | |
| 2017 | Added a new function ext2fs_dblist_count returns the number of |
| 2018 | directory blocks in dblist. |
| 2019 | |
| 2020 | |
Theodore Ts'o | ae85148 | 1997-04-29 18:13:24 +0000 | [diff] [blame] | 2021 | E2fsprogs 1.10 (April 24, 1997) |
| 2022 | =============================== |
| 2023 | |
| 2024 | Mke2fs once again defaults to creating revision #0 filesystems, since |
| 2025 | people were complaining about breaking compatibility with 1.2 kernels. |
| 2026 | Warning messages were added to the mke2fs and tune2fs man pages that |
| 2027 | the sparse superblock option isn't supported by most kernels yet (1.2 |
| 2028 | and 2.0 both don't support parse superblocks.) |
| 2029 | |
| 2030 | Added new flag to mke2fs, -R <raid options>, which allows the user to |
| 2031 | tell mke2fs about the RAID configuration of the filesystem. Currently |
| 2032 | the only supported raid option is "stride" which specifies the width |
| 2033 | of the RAID stripe. |
| 2034 | |
| 2035 | Fixed bug in e2fsck where pass1b would bomb out if there were any |
| 2036 | blocks marked bad in the inode table. |
| 2037 | |
| 2038 | Fixed rare bug in mke2fs where if the user had a very unlucky number |
| 2039 | of blocks in a filesystem (probability less than .002) the resulting |
| 2040 | filesystem would be corrupt in the last block group. |
| 2041 | |
| 2042 | Fixed bug where if e2fsck tried to allocate a block to fix a |
| 2043 | filesystem corruption problem and the filesystem had no free blocks, |
| 2044 | ext2fs_new_block() would loop forever. |
| 2045 | |
| 2046 | The configure script now checks explicitly to see if "-static" works, |
| 2047 | since that can't be assumed to be true --- RedHat doesn't install |
| 2048 | libc-static by default. |
| 2049 | |
| 2050 | Fixed bug in libext2's block iterator functions where under some |
| 2051 | cirmcustances, file with holes would cause the bcount parameter to the |
| 2052 | callback function to be incorrect. This bug didn't affect any of |
| 2053 | e2fsprogs programs, but it was discovered by Paul Mackerras, the |
| 2054 | author of the PPC boot loader. |
| 2055 | |
| 2056 | Removed use of static variables to store the inode cache in libext2fs. |
| 2057 | This caused problems if more than one filesystem was accessed via |
| 2058 | libext2fs (static variables in libraries are generally a bad idea). |
| 2059 | Again, this didn't affect e2fsprogs programs, but it was discovered by |
| 2060 | Paul Mackerras. |
| 2061 | |
| 2062 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 |
| 2063 | will compile cleanly with 1.2.13 kernels (even with a.out shared |
| 2064 | libraries!) |
| 2065 | |
| 2066 | Programmer's notes: |
| 2067 | ------------------- |
| 2068 | |
| 2069 | Added new functions to duplicate an ext2 filesystem handle, and its |
| 2070 | associated substructure. New functions: ext2fs_dup_handle(), |
| 2071 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). |
| 2072 | Other structures, such as the io_channel and the inode_cache, now have |
| 2073 | a ref count so that they only get freed when they are no longer used |
| 2074 | by any filesystem handle. (These functions were added as part of the |
| 2075 | development effort for an ext2 resizer). |
| 2076 | |
Theodore Ts'o | 2ecc6fe | 1997-04-29 17:57:00 +0000 | [diff] [blame] | 2077 | E2fsprogs 1.09 (April 14, 1997) |
| 2078 | =============================== |
| 2079 | |
| 2080 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was |
| 2081 | accidentally introduced in the 1.08 release. The overhead calculation |
| 2082 | was accidentally removed, which caused ext2fs_initialize() to not |
| 2083 | notice when the filesystem size needed to be adjusted down because |
| 2084 | there wasn't enough space in the last block group. |
| 2085 | |
| 2086 | Fixed bug in version parsing library routine; it was always parsing |
| 2087 | the library version string, instead of using the passed-in string. |
| 2088 | |
| 2089 | Clarified chattr man page. |
| 2090 | |
Theodore Ts'o | 24757fa | 1997-04-29 17:39:27 +0000 | [diff] [blame] | 2091 | E2fsprogs 1.08 (April 10, 1997) |
| 2092 | =============================== |
| 2093 | |
| 2094 | E2fsck 1.07 was very slow when checking very large filesystems with a |
| 2095 | lot of files that had hard links (i.e., news spools). This was fixed |
| 2096 | by seriously revamping the icount abstraction. Added a formal test |
| 2097 | suite for the icount abstraction. |
| 2098 | |
| 2099 | Debugfs now has a "-l" option to the "ls" command, which lists the |
| 2100 | inode number, permissions, owner, group, size, and name of the files |
| 2101 | in the directory. |
| 2102 | |
| 2103 | Fix a bug in e2fsck where when a directory had its blocks moved to |
| 2104 | another location during the pass 1b processing, the directory block |
| 2105 | list wasn't updated, so pass 2 wouldn't check (and correct) the |
| 2106 | correct directory block. |
| 2107 | |
| 2108 | E2fsck will now treat inodes which contain blocks which are claimed by |
| 2109 | the filesystem metadata by treating them as multiply claimed blocks. |
| 2110 | This way, the data in those blocks can be copied to a new block during |
| 2111 | the pass 1b--1d processing. |
| 2112 | |
| 2113 | E2fsck will attempt to determine the correct superblock number and |
| 2114 | display it in the diagnostic and warning messages if possible. |
| 2115 | |
| 2116 | Add support for a new (incompatible) feature, "sparse_super". This |
| 2117 | feature reduces the number of blocks which contain copies of backup |
| 2118 | superblocks and block group descriptors. (It is only an incompatible |
| 2119 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now |
| 2120 | support a new -s option; e2fsck will recognize filesystems built with |
| 2121 | this feature turned on. |
| 2122 | |
| 2123 | E2fsck now checks the library to make sure is the correct version, |
| 2124 | using new library functions. (This helps to diagnose incorrectly |
| 2125 | installed e2fsprogs distributions.) |
| 2126 | |
| 2127 | Dumpe2fs now prints more information; its now prints the the |
| 2128 | filesystem revision number, the filesystem sparse_super feature (if |
| 2129 | present), the block ranges for each block group, and the offset from |
| 2130 | the beginning of the block group. |
| 2131 | |
| 2132 | Mke2fs now distributes the inode and block bitmap blok so that the |
| 2133 | won't be concentrated in one or two disks in RAID/striping setups. |
| 2134 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to |
| 2135 | choose the largest blocks per group that be chosen. (For 2k blocks, |
| 2136 | you can have up to 16384 blocks/group; for 4k blocks, you can have up |
| 2137 | to 32768 blocks/group.) Previously mke2fs would not allow |
| 2138 | specification of more than 8192 blocks per group, even if you were |
| 2139 | using a 2k or 4k block group. |
| 2140 | |
| 2141 | Programmer's notes: |
| 2142 | ------------------- |
| 2143 | |
| 2144 | Added a new function ext2fs_create_icount2() which takes a "hint" |
| 2145 | argument. This hint argument presets the icount array with the list |
| 2146 | of inodes which actually need to be in the icount array. This really |
| 2147 | helps to speed up e2fsck. |
| 2148 | |
| 2149 | Added a new function ext2fs_icount_validate() which checks the rep |
| 2150 | invariant for the icount structure. This is used mostly for testing. |
| 2151 | |
| 2152 | The error mesasage given when a bad inode number is passed to |
| 2153 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of |
| 2154 | EXT2FS_UNMARK_ERROR). |
| 2155 | |
| 2156 | Added a new function ext2fs_set_dir_block which sets the block of a |
| 2157 | dblist entry, given the directory inode and blockcnt. |
| 2158 | |
| 2159 | Added a new function ext2fs_get_library_version() which returns the |
| 2160 | current library version, and ext2fs_parse_version_string() which |
| 2161 | returns a version number based on a e2fsprogs version string. |
| 2162 | |
| 2163 | The icount functions will return EINVAL if the passed in inode number |
| 2164 | is out of bounds. |
| 2165 | |
Theodore Ts'o | 21c84b7 | 1997-04-29 16:15:03 +0000 | [diff] [blame] | 2166 | E2fsprogs 1.07 (March 9, 1997) |
| 2167 | ============================== |
| 2168 | |
| 2169 | E2fsck is now uses much less memory when checking really large |
| 2170 | filesystems (or rather, filesystems with a large number of inodes). |
| 2171 | Previously a filesystem with 1 million inodes required 4 megabytes of |
| 2172 | memory to store inode count statistics; that storage requirement has |
| 2173 | now been reduced to roughly half a megabyte. |
| 2174 | |
| 2175 | E2fsck can now properly deal with bad blocks appearing inside the |
| 2176 | inode table. Instead of trying to relocate the inode table (which |
| 2177 | often failed because there wasn't enough space), the inodes in the bad |
| 2178 | block are marked as in use. |
| 2179 | |
| 2180 | E2fsck will automatically try to use the backup superblocks if the |
| 2181 | primary superblocks have a bad magic number or have missing meta-data |
| 2182 | blocks (or meta-data blocks which are out of range). |
| 2183 | |
| 2184 | E2fsck's pass 3 has been made more efficient; most noticeable on |
| 2185 | filesystems with a very large number of directories. |
| 2186 | |
| 2187 | Completely revamped e2fsck's system of printing problem reports. It |
| 2188 | is now table driven, to make them more easily customizeable and |
| 2189 | extendable. Error messages which can be printed out during preen mode |
| 2190 | are now one line long. |
| 2191 | |
| 2192 | Fixed e2fsck's filesystem swapping code so that it won't try to swap |
| 2193 | fast symbolic links or deleted files. |
| 2194 | |
| 2195 | Fixed e2fsck core dumping when fixing a filesystem which has no |
| 2196 | directories (not even a root directory). |
| 2197 | |
| 2198 | Added a check to e2fsck to make sure that the length of every |
| 2199 | directory entry is a multiple of 4 (since the kernel complains if it |
| 2200 | isn't). |
| 2201 | |
| 2202 | Added a check to e2fsck to make sure that a directory entry isn't a |
| 2203 | link to the root directory, since that isn't allowed. |
| 2204 | |
| 2205 | Added a check to e2fsk to now make sure the '.' and '..' directory |
| 2206 | entries are null terminated, since the 2.0 kernel requires it. |
| 2207 | |
| 2208 | Added check to write_bitmaps() to make sure the superblock doesn't get |
| 2209 | trashed if the inode or block bitmap is marked as being block zero. |
| 2210 | |
| 2211 | Added checking of the new feature set fields in the superblock, to |
| 2212 | avoid dealing with new filesystem features that this package wasn't |
| 2213 | set up to handle. |
| 2214 | |
| 2215 | Fixed a fencepost error in ext2fs_new_block() which would occasionally |
| 2216 | try to allocate a block beyond the end of a filesystem. |
| 2217 | |
| 2218 | When the UUID library picks a random IEEE 802 address (because it |
| 2219 | can't find one from a network card), it sets the multicast bit, to |
| 2220 | avoid conflicting with a legitimate IEEE 802 address. |
| 2221 | |
| 2222 | Mke2fs now sets the root directory's owner to be the real uid of the |
| 2223 | user running mke2fs. If the real uid is non-zero, it also sets |
| 2224 | the group ownership of the root directory to be the real group-id of |
| 2225 | the user running mke2fs. |
| 2226 | |
| 2227 | Mke2fs now has more intelligent error checking when it is given a |
| 2228 | non-existent device. |
| 2229 | |
| 2230 | When badblocks is given the -vv option, it now updates the block that |
| 2231 | it is currently testing on every block. |
| 2232 | |
| 2233 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment |
| 2234 | currently correctly if PATH wasn't already set. |
| 2235 | |
| 2236 | Shared libraries now built with dependencies. This allows the shared |
| 2237 | library files to be used with dlopen(); it also makes the transition |
| 2238 | to libc 6 easier, since ld.so can tell which libc a particular shared |
| 2239 | library expects to use. |
| 2240 | |
| 2241 | Programmer's notes: |
| 2242 | ------------------- |
| 2243 | |
| 2244 | Added new abstraction (defined in dblist.c) for maintaining a list of |
| 2245 | blocks which belongs to directories. This is used in e2fsck and other |
| 2246 | programs which need to iterate over all directories. |
| 2247 | |
| 2248 | Added new functions which test to see if a contiguous range of blocks |
| 2249 | (or inodes) are available. (ext2fs_*_bitmap_range). |
| 2250 | |
| 2251 | Added new function (ext2_inode_has_valid_blocks) which returns true if |
| 2252 | an inode has valid blocks. (moved from e2fsck code). |
| 2253 | |
| 2254 | Added new function (ext2fs_allocate_tables) which allocates the |
| 2255 | meta-data blocks as part of initializing a filesystem. (moved from |
| 2256 | mke2fs code). |
| 2257 | |
| 2258 | Added a new I/O manager for testing purposes. It will either allow a |
| 2259 | program to intercept I/O requests, or print debugging messages to |
| 2260 | trace the activity of a program using the I/O manager. |
| 2261 | |
| 2262 | The badblocks_list functions now store the bad blocks in a sorted |
| 2263 | order, and use a binary search to speed up badblocks_list_test. |
| 2264 | |
| 2265 | The inode scan function ext2fs_get_next_inode() may now return a soft |
| 2266 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in |
| 2267 | those cases where part of an inode table is missing or there is a bad |
| 2268 | block in the inode table. |
| 2269 | |
| 2270 | Added a new function (ext2fs_block_iterate2) which adds new arguments to |
| 2271 | the callback function to return a pointer (block and offset) to the |
| 2272 | reference of the block. |
| 2273 | |
| 2274 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an |
| 2275 | application to jump to a particular block group while doing an inode |
| 2276 | scan. |
| 2277 | |
| 2278 | The badblocks list functions were renamed from badblocks_* to |
| 2279 | ext2fs_badblocks_*. Backwards compatibility functions are available |
| 2280 | for now, but programs should be modified to use the new interface. |
| 2281 | |
| 2282 | Some of the library functions were reorganized into separate files to |
| 2283 | reduce the size of some programs which statically link against the |
| 2284 | ext2 library. |
| 2285 | |
| 2286 | Put in some miscellaneous fixes for the Alpha platform. |
| 2287 | |

| 2289 | E2fsprogs 1.06 (October 7, 1996) |
| 2290 | ================================ |
| 2291 | |
| 2292 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't |
| 2293 | smash the backup copies in ext2fs_close(). (The problem was that when |
| 2294 | e2fsck -p discovered the problem, while it was closing the filesystem |
| 2295 | and exiting, it was also blowing away the backup superblocks on the |
| 2296 | disk, which was less than friendly.) We now make it the case that we |
| 2297 | only write out the backup superblock and the back block descriptors if |
| 2298 | the filesystem is completely free from problems. |
| 2299 | |
| 2300 | Fixed a bug in block_interate in the lib/ext2fs library which caused |
| 2301 | e2fsck to fail on GNU Hurd-created filesystems. |
| 2302 | |
| 2303 | Add support for Linux/FT's bootloader, which actually uses |
| 2304 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want |
| 2305 | to clear the inode. |
| 2306 | |
| 2307 | Add support for the "A" (no atime update) attribute. (Note: this |
| 2308 | attribute is not yet in production kernels.) |
| 2309 | |
| 2310 | The test suite is not automatically run when doing a "make all" from |
| 2311 | the top level directory. Users should manually run "make check" if |
| 2312 | they wish to run the test suite. |
| 2313 | |
| 2314 | Upon a preenhalt(), make the printed message more explicit that |
| 2315 | running e2fsck "MANAULLY" means without the -p or -a options. |
| 2316 | |
| 2317 | In e2fsck, if a disconnected inode is zero-length, offer to clear it |
| 2318 | instead of offering to connect it to lost+found. |
| 2319 | |
| 2320 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs |
| 2321 | e2fsck to be run over it, change e2fsck to explicitly display this |
| 2322 | fact. |
| 2323 | |
| 2324 | For dumpe2fs and e2fsck, cause the -V option to print out which |
| 2325 | version of the ext2fs library is actually getting used. (This will |
| 2326 | help detect mismatches of using a 1.06 utility with a 1.05 library, |
| 2327 | etc.) |
| 2328 | |
| 2329 | Programmers' notes: |
| 2330 | ------------------- |
| 2331 | |
| 2332 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits |
| 2333 | the naming convention. |
| 2334 | |
| 2335 | In ext2fs_initialize(), make sure the description for the inode bitmap |
| 2336 | is correctly initialize. |
| 2337 | |
| 2338 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); |
| 2339 | |
Theodore Ts'o | fc6d9d5 | 1997-04-29 14:51:31 +0000 | [diff] [blame] | 2340 | E2fsprogs 1.05 (September 7, 1996) |
| 2341 | ================================== |
| 2342 | |
| 2343 | Add support for new fields in the ext2 superblock --- volume name, |
| 2344 | volume UUID, and last mounted field. Dumpe2fs displays these fields, |
| 2345 | tune2fs and mke2fs allows you to set them. E2fsck will automatically |
| 2346 | generate a UUID for those volumes that don't have them. |
| 2347 | |
| 2348 | Put in support for e2fsck to recognize HURD specific ext2 features --- |
| 2349 | most notably, the translator block. The e2fsprogs tools will now use |
| 2350 | the creator_os field in the superblock to correctly handle different |
| 2351 | OS-specific variants of the ext2 filesystem. |
| 2352 | |
| 2353 | E2fsck now fixes inodes which have a the deletion time set, but which |
| 2354 | have a non-zero i_link_count field by offering to clear the deletion |
| 2355 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c |
| 2356 | ext2 kernel behavior) and offered to unlink the file. |
| 2357 | |
| 2358 | If e2fsck sets the clean bit, but nothing else, set the exit code |
| 2359 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it |
| 2360 | set the filesystem valid bit when it was previously cleared. :-) This |
| 2361 | was needed to make the HURD fsck driver happy. |
| 2362 | |
| 2363 | If the user refuses to attach an unattached inode, e2fsck will no |
| 2364 | longer set the inode's link count. Otherwise, the inode would end up |
| 2365 | getting marked as unused, which might cause loss of data later. |
| 2366 | |
| 2367 | Make the message issued by e2fsck when the superblock is corrupt less |
| 2368 | confusing for users. It now mentions that another reason for the |
| 2369 | "corrupt superblock" message might be that the partition might not be |
| 2370 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) |
| 2371 | |
| 2372 | Make the libext2 library more robuest so that e2fsck won't coredump on |
| 2373 | an illegal superblock where the blocksize is zero. (f_crashdisk is |
| 2374 | the test case). |
| 2375 | |
| 2376 | By default, create filesystems where the default checkinterval is 6 |
| 2377 | months (180 days). Linux servers can be robust enough that 20 reboots |
| 2378 | can be a long, long time. |
| 2379 | |
| 2380 | Added configure flag --enable-old-bitops, which forces the bitops to |
| 2381 | use the old (native) bitmask operations. By default on the sparc |
| 2382 | platform, the standard ext2 bit ordering is now used. |
| 2383 | |
| 2384 | Added a new feature to e2fsck to byte-swap filesystems; this can be |
| 2385 | used to convert old m68k filesystems to use the standard byte-order |
| 2386 | storage for the superblock, inodes, and directory blocks. This |
| 2387 | function is invoked by using the '-s' option to e2fsck. |
| 2388 | |
| 2389 | Debugfs's "dump" command has been enhanced so that it writes out the |
| 2390 | exact size of the file so that the nulls at the end of the file are |
| 2391 | eliminated. The command also accept a new "-p" option which will |
| 2392 | attempt preserve to preserve the ownernship, permissions, and |
| 2393 | file modification/access times. |
| 2394 | |
| 2395 | Debugfs has two new options, -f and -R. The -R option allows the user |
| 2396 | to execute a single debugfs command from the command line. The -f |
| 2397 | option allows the user to specify a "command file" containing debugfs |
| 2398 | commands which will get executed. |
| 2399 | |
| 2400 | Dumpe2fs now pretty prints the check interval, instead of just |
| 2401 | printing the check interval as a number of seconds. |
| 2402 | |
| 2403 | Fix bugs in debugfs: the params command when no filesystem is opened |
| 2404 | no longer causes a core dump. It is now possible to unlink a file |
| 2405 | when a pathame containing a '/' is specified. |
| 2406 | |
| 2407 | Tune2fs has a new -C option which sets the number of times the |
| 2408 | filesystem has been mounted. |
| 2409 | |
| 2410 | Fix the chattr '-v' option so that it actually works. Chattr was |
| 2411 | being buggy about the -v option parsing. |
| 2412 | |
| 2413 | Programmers' notes: |
| 2414 | ------------------- |
| 2415 | |
| 2416 | The directory lib/uuid contains a set of library routines to generate |
| 2417 | DCE compatible UUIDs. |
| 2418 | |
| 2419 | Extended ext2fs_namei() to handle symbolic links. Added new function |
| 2420 | ext2fs_nami_follow() which will follow last symbolic link in the case |
| 2421 | where the pathname points to a sym link. |
| 2422 | |
| 2423 | The ext2fs_block_iterate function will now return the HURD translator |
| 2424 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the |
| 2425 | iterator to return data blocks only. The ext2fs.h file now defines |
| 2426 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and |
| 2427 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block |
| 2428 | count field of the iterator callback function. |
| 2429 | |
| 2430 | The test script driver now takes an optional second argument, which is |
| 2431 | the test case to be run. This allows you to run a test case without |
| 2432 | needing to run the entire test suite. |
| 2433 | |
| 2434 | On Linux ELF systems, install the .so files in the correct places |
| 2435 | (/usr/lib). The .so files must be stored in the same directory as the |
| 2436 | .a files. |
| 2437 | |
| 2438 | Fixed miscellaneous HURD compilation issues with header file being |
| 2439 | included in the right order. |
| 2440 | |
| 2441 | Fixed debugfs so that it resets optind to zero, not one, since setting |
| 2442 | optind to zero is more correct. |
| 2443 | |
| 2444 | |
Theodore Ts'o | a4d0961 | 1997-04-29 14:28:00 +0000 | [diff] [blame] | 2445 | E2fsprogs 1.04 (May 16, 1996) |
| 2446 | ============================= |
| 2447 | |
| 2448 | First "official" (1.03 was a limited release only) to support building |
| 2449 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 |
| 2450 | kernels). |
| 2451 | |
| 2452 | This package includes a RPM specs file, that it can be built using the |
| 2453 | RedHat Package Manager. |
| 2454 | |
| 2455 | E2fsck now prints a hint that if there are lots of incorrectly located |
| 2456 | inode bitmaps, block bitmaps, and inode table blocks, the user might |
| 2457 | want to try using e2fsck -b 8193 first, to see if that fares any |
| 2458 | better. |
| 2459 | |
| 2460 | For ext2 filesystem written with the hurd, debugfs will now print out |
| 2461 | the translator field when printing an inode structure. |
| 2462 | |
| 2463 | Lots of miscellaneous linking/installation cleanups: |
| 2464 | |
| 2465 | Libraries are now linked using a relative pathname, instead of |
| 2466 | relying on -L working correct. It doesn't, in many cases, including |
| 2467 | current versions of GNU ld. This guarantees that the build tree is |
| 2468 | linking with the right libraries, instead of the ones installed in |
| 2469 | /usr/lib. |
| 2470 | |
| 2471 | Header files, man pages, and the et/ss shell scripts are now |
| 2472 | generated using a custom substitution script, instead of relying on |
| 2473 | the configure script. This prevents needless recompilation of |
| 2474 | files; in addition, the custom substitution script is much faster. |
| 2475 | |
| 2476 | e2fsck may now be linked dynamically, by using the |
| 2477 | --enable-dynamic-e2fsck flag to configure. This is not recommended, |
| 2478 | since it increases e2fsck's dependence on other files, but some |
| 2479 | people need to save disk space, and other critical programs on their |
| 2480 | systems were being linked dynamically anyway. |
| 2481 | |
| 2482 | Programs such as fsck which didn't need to be linked against |
| 2483 | libext2fs (or mke2fs which didn't need to be linked against libe2p) |
| 2484 | only link against libraries they actually need. Otherwise, those |
| 2485 | programs would require the presense of libraries that otherwise |
| 2486 | could be removed from a rescuse diskette. |
| 2487 | |
| 2488 | The ss include files are now installed correctly so they can |
| 2489 | actually be used by another package. |
| 2490 | |
| 2491 | If the profiling libraries are built, they are now installed on a |
| 2492 | "make install-libs". |
| 2493 | |
| 2494 | |
Theodore Ts'o | 7f88b04 | 1997-04-26 14:48:50 +0000 | [diff] [blame] | 2495 | E2fsprogs 1.03 (March 27, 1996) |
| 2496 | =============================== |
| 2497 | |
| 2498 | Change the m68k bit numbering for bitmasks to match the bit numbering |
| 2499 | used by all other ext2 implementations. (This change was requested by |
| 2500 | the m68k kernel development team.) |
| 2501 | |
| 2502 | Support (in-development) filesystem format revision which supports |
| 2503 | (among other things) dynamically sized inodes. |
| 2504 | |
| 2505 | Fixed a bug in the ext2 library so that an intelligent error is |
| 2506 | returned if mke2fs is run with a ridiculously small number of blocks |
| 2507 | for a partition. |
| 2508 | |
| 2509 | Fixed a bug in the ext2 library which required that the device be |
| 2510 | openable in read/write mode in order to determine its size. This |
| 2511 | caused e2fsck -n to require read/write access when it was not |
| 2512 | previously necessary. |
| 2513 | |
| 2514 | Fixed a bug in e2fsck which casued it to occasionally fail the test |
| 2515 | suite depending on which version of the floating point library it was |
| 2516 | using. |
| 2517 | |
| 2518 | Fixed a bug in e2fsck so that it now halts with a fatal error when |
| 2519 | certain superblock consistency checks fail. Previously it continued |
| 2520 | running e2fsck, with some potential confusing/damaging consequences. |
| 2521 | |
| 2522 | Added new flag to fsck which allows the root to be checked in parallel |
| 2523 | with other filesytems. This is not the safest thing in the world to |
| 2524 | do, but some system administrators really wanted it. |
| 2525 | |
Theodore Ts'o | fc6d9d5 | 1997-04-29 14:51:31 +0000 | [diff] [blame] | 2526 | Fixed -Wall flames in lib/ss. |

Theodore Ts'o | 74becf3 | 1997-04-26 14:37:06 +0000 | [diff] [blame] | 2528 | |
| 2529 | E2fsprogs 1.02 (January 16, 1996) |
| 2530 | ================================= |
| 2531 | |
| 2532 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. |
| 2533 | |
| 2534 | Change e2fsck to print statistics of how many non-contiguous files are |
| 2535 | on the system. Note that a file which is larger than 8k blocks, it is |
| 2536 | guaranteed to be non-contiguous. |
| 2537 | |
| 2538 | In mke2fs, print a warning message if a user tries to format a whole |
| 2539 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a |
| 2540 | whole disk, the -F (force) option forces mke2fs to format a whole disk |

| 2543 | Fix a bug in fsck where in some cases it might start checking |
| 2544 | partitions in the next pass before it finishes checking partitions in |
| 2545 | the current pass. This still won't cause two partitions on the same |
| 2546 | disk will be checked, so it's rarely a problem in real life. |
| 2547 | |
| 2548 | Patch lsattr so that it won't hang when checking a named pipe. |
| 2549 | |
| 2550 | Minor compilation fixes: |
| 2551 | * Fix the order of libraries that were linked in debugfs. |
| 2552 | * Allow the sources to be compiled with -ansi turned on. |
