71df0dc3 | 1 | E2fsprogs 1.33 (April 21, 2003) |
508d7f3c TT |
2 | =================================== |
3 | ||
ba142c1b TT |
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 | ||
39d38b05 | 41 | Update Debian files to reflect the fact that I am now the Debian |
ba142c1b TT |
42 | maintainer of e2fsprogs. Other various Debian-specific packaging |
43 | cleanups. | |
39d38b05 TT |
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 | ||
508d7f3c TT |
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 | |
ba142c1b TT |
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. | |
3809bf1d | 65 | |
e5dced7f TT |
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 | ||
3809bf1d TT |
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 | |
ba142c1b | 113 | #173612, #175233, #175113, and #170497, #185945, #188318) |
3809bf1d | 114 | |
508d7f3c TT |
115 | Created man page for the mk_cmds program (from the libss library). |
116 | ||
3809bf1d TT |
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 | |
e5dced7f TT |
123 | successfully under Solaris and Apple/Darwin. |
124 | ||
125 | Fixed a Makefile dependency to allow building e2fsprogs using parallel | |
126 | make jobs. | |
3809bf1d TT |
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 | ||
ba142c1b TT |
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 | ||
508d7f3c TT |
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. | |
3809bf1d | 139 | |
71df0dc3 TT |
140 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
141 | chattr, and blkid executables. | |
142 | ||
38513011 TT |
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 | ||
3809bf1d | 157 | |
ae65b29f TT |
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 | ||
5d823a47 TT |
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. | |
d5e7810e TT |
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 | ||
5d823a47 | 318 | Updated and clarified man pages. (Addresses Debian bug #167108) |

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. :-) | |
351 | ||
352 | ||
b7bad615 TT |
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. | |
498 | ||

500 | E2fsprogs 1.27 (March 8, 2002) |
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. | |
afa14ba0 TT |
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 | ||
a471ac52 TT |
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 | ||
afa14ba0 TT |
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 | ||
a471ac52 TT |
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 | ||
afa14ba0 TT |
541 | Programmer's notes: |
542 | ------------------- | |
543 | ||
a8e77249 TT |
544 | Fixed various gcc -Wall complaints. |
545 | ||
afa14ba0 TT |
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 | ||
560 | ||
0698739a | 561 | E2fsprogs 1.26 (February 3, 2002) |
a5f3f5c1 | 562 | ================================= |
cd1a79a5 | 563 | |
446314fc TT |
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 | ||
cd1a79a5 TT |
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 | ||
a5f3f5c1 TT |
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 | ||
446314fc TT |
612 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
613 | should be searched for UUID and label information. | |
614 | ||
cd1a79a5 TT |
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 | ||
446314fc TT |
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 | ||
cd1a79a5 TT |
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 | ||
446314fc TT |
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 | ||
a5f3f5c1 TT |
645 | Added a new option (-T) to tune2fs which sets the time a filesystem |
646 | was last checked. | |
647 | ||
cd1a79a5 TT |
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 | ||
446314fc TT |
660 | Debugfs's rm and kill_file command now updates the superblock free block |
661 | and inode counts, thus keeping the filesystem consistent. | |
662 | ||
a5f3f5c1 TT |
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 | ||
cd1a79a5 TT |
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 | ||
446314fc | 687 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
cd1a79a5 TT |
688 | |
689 | Added new translation file for Turkish. | |
690 | ||
446314fc TT |
691 | Programmer's notes: |
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 | ||
a5f3f5c1 TT |
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. | |

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). | |
771 | ||
772 | ||
fb70775b TT |
773 | E2fsprogs 1.24a (September 2, 2001) |
774 | =================================== | |
775 | ||
776 | Fix brown-paper bug in mke2fs which caused it to segfault when | |
777 | printing the version string. | |
778 | ||
779 | ||
109624a1 TT |
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 | ================================ | |
d1ef5c34 TT |
813 | |
814 | Add initial support for extended attributes (EA); e2fsck will | |
6c0a0417 TT |
815 | correctly handle a filesystem with EA's and check the EA blocks for |
816 | corruptions. | |
817 | ||
d494bba8 TT |
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 | ||
c4ac9e14 TT |
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 | ||
d494bba8 TT |
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. | |
bf16d106 TT |
830 | |
831 | Add support for the 64-bit block device patches. | |
832 | ||
833 | Fixed bugs in creating external journals with a 1k blocksize. | |
834 | ||
d494bba8 TT |
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 | ||
bf16d106 | 841 | The man pages now document how to create and manage external journals. |
d1ef5c34 TT |
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 | ||
d494bba8 TT |
846 | Speed up creating an internal journal using tune2fs in the case where |
847 | the filesystem has a lot blocks already allocated. | |
848 | ||
c4ac9e14 TT |
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 | ||
d494bba8 | 852 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
c4ac9e14 | 853 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
d494bba8 | 854 | |
d1ef5c34 TT |
855 | Add support in fsck for the filesystem type "auto". |

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 | ||

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 | ||
d494bba8 | 866 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
c4ac9e14 TT |
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. | |
d494bba8 TT |
869 | |
870 | E2fsck now prints the number of large files when given the -v option. | |
871 | ||
872 | Fixed minor memory leaks in e2fsck. | |
bf16d106 | 873 | |
c4ac9e14 | 874 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |

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 | ||
b90b826b TT |
909 | E2fsprogs 1.21 (June 15, 2001) |
910 | ============================== | |
911 | ||
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 | |
c05b5521 TT |
939 | ext3 0.7a. |
940 | ||
767de097 TT |
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 | ||
5a9c036b TT |
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 | ||
767de097 TT |
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 | |
e333845b | 954 | entirely. (Addresses Debian bug #98527.) |
767de097 | 955 | |
b90b826b TT |
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 | ||
c05b5521 TT |
960 | Fixed a bug in debugfs which caused read errors when copying a file to |
961 | not be noticed. | |
962 | ||
b90b826b TT |
963 | The debugfs set_super_value command can now modify the s_lastcheck field. |
964 | ||
c05b5521 TT |
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 | ||
b90b826b TT |
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 | ||
767de097 TT |
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 | ||
c05b5521 | 982 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
983 | in ext2_types.h. Also, if linux/types.h has already been defined, |
984 | don't try to redefine the types. | |
c05b5521 | 985 | |
767de097 TT |
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 | ||
c05b5521 TT |
996 | Fixed a performance bug in the libext2fs's icount routine; the size |
997 | estimate of the icount array was incorrectly being calculated. | |
998 | ||
b90b826b TT |
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. | |

5a009bb9 | 1029 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 1030 | ============================= |
5570a65a | 1031 | |
31d1d0c8 TT |
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. | |
5570a65a TT |
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 | ||
31d1d0c8 TT |
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 | ||
77648565 | 1089 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
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 | ||
5570a65a TT |
1095 | Fixed bug in the progress bar printing code which could cause e2fsck |
1096 | to core dump on an illegal filesystem. | |
1097 | ||
31d1d0c8 TT |
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 | ||
5570a65a TT |
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 | |
31d1d0c8 TT |
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. | |
5570a65a | 1111 | |
5a009bb9 TT |
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 | ||
5570a65a TT |
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 | ||
31d1d0c8 TT |
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 | ||
5570a65a TT |
1157 | |
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 | ||
31d1d0c8 TT |
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 | ||
5570a65a TT |
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 | ||
31d1d0c8 TT |
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 | ||
5570a65a TT |
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 | ||
31d1d0c8 TT |
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 | |
7d614e3d TT |
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. | |
31d1d0c8 TT |
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. | |
5570a65a | 1234 | |
b777e26e TT |
1235 | E2fsprogs 1.19 (July 13, 2000) |
1236 | ============================== | |
ab146766 TT |
1237 | |
1238 | Release the resize2fs program since the timeout before it could | |
006ea71e | 1239 | be released under the GPL has finally expired. |
ab146766 TT |
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 | ||
31d1d0c8 TT |
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 | ||
ab146766 TT |
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 | |
006ea71e TT |
1304 | feature which causes badblocks to run until it has completed some |
1305 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
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. | |
1400 | ||
31d1d0c8 TT |
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.) | |
ab146766 TT |
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. | |
1414 | ||
1415 | ||

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 | ||
28e1194e TT |
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 | ||
8a31ffef TT |
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 | ||
1583 | ||
a39f3efe | 1584 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 1585 | ============================== |
6d53db3f TT |
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 | ||
e2a99be6 TT |
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 | ||
a39f3efe TT |
1602 | Mke2fs now creates revision 1 filesystems by default, and with the |
1603 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
1604 | not understood by Linux 2.0 kernels, so they will only allow read-only |
1605 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 1606 | |
6d53db3f TT |
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 | ||
e2a99be6 TT |
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 | ||
6d53db3f TT |
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 | |
a39f3efe TT |
1667 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
1668 | needed for most Linux 2.2 users. | |
6d53db3f TT |
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 | ||
14790ed7 TT |
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 | ||
556ad132 TT |
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... | |
1804 | ||
a569671a | 1805 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
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 | ||
c9833a60 TT |
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, | |
101c84f2 TT |
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 | ||
21d53850 TT |
1831 | Added new program "e2label", contributed by Andries Brouwer. E2label |
1832 | provides an easy-to-use interface to modify the filesystem label. | |
1833 | ||
a4b2d3ce TT |
1834 | Fixed bug so that lsattr -v works instead of producing a core dump. |
1835 | ||
21d53850 TT |
1836 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
1837 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
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 | ||
c9833a60 TT |
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 | ||
21d53850 TT |
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 | ||
1958 | ||
bc210074 TT |
1959 | E2fsprosg 1.11 (June 17, 1997) |
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 | |
21d53850 | 1980 | really big filesystem. |
bc210074 TT |
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 | ||
ae851482 TT |
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 | ||

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. | |

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 | ||

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. | |

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 | ||
fc6d9d51 TT |
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 | ||

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. | |

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". | |

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 | ||

2526 | Fixed -Wall flames in lib/ss. |

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 | |
2541 | as a filesytem. | |
2542 | ||
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. |
