1 | E2fsprogs 1.21 (June 15, 2001) |
2 | ============================== | |
3 | ||
4 | Added new configure flags which allow a subset e2fsprogs to be built; | |
5 | this is most useful for boot floopies, since the resulting shared | |
6 | libraries and programs are slimmed down by removing features that | |
7 | aren't necessary for a boot floppy. The new flags that were added | |
8 | are: --disable-swapfs, which removes support for byte swapping old | |
9 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
10 | for debugfs from the libext2fs library, --disable-imager, which | |
11 | removes support for the e2image program, and --disable-resizer, which | |
12 | removes support for resize2fs. | |
13 | ||
14 | E2fsck now prints the number of mounts or days elapsed since the last | |
15 | check when e2fsck is forced to check an otherwise clean filesystem. | |
16 | ||
17 | Tune2fs now prints an informative message about how often a filesystem | |
18 | will be checked when adding a journal to the filesystem, to remind the | |
19 | user that he/she may want to adjust those parameters using tune2fs | |
20 | -c/-i. | |
21 | ||
22 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
23 | believe a filesystem is the root filesystem based on device numbers | |
24 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
25 | violation). | |
26 | ||
27 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
28 | erroneous error with the -F option was specified. | |
29 | ||
30 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
c05b5521 TT |
31 | ext3 0.7a. |
32 | ||
767de097 TT |
33 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
34 | with relatively uncommon edge cases: a directory with an indirect | |
35 | block which is claimed by another file, and when the last inode in the | |
36 | filesystem has blocks claimed by another file. | |
37 | ||
5a9c036b TT |
38 | E2fsck now checks to see if the i_size field of a fast symlink is too |
39 | big, and offers to clear the symlink if so. | |
40 | ||
41 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
42 | and offers to clear i_size_high. | |
43 | ||
767de097 TT |
44 | Fix e2fsck's handling of incompatible journal flags so that the user |
45 | has chance to abort, and then has the option to clear out the journal | |
e333845b | 46 | entirely. (Addresses Debian bug #98527.) |
767de097 | 47 | |
b90b826b TT |
48 | Fixed a bug in fsck which could cause it to core dump if a mix of |
49 | standard and non-standard device names are used in /etc/fstab. | |
50 | (Debian bug #100559) | |
51 | ||
c05b5521 TT |
52 | Fixed a bug in debugfs which caused read errors when copying a file to |
53 | not be noticed. | |
54 | ||
b90b826b TT |
55 | The debugfs set_super_value command can now modify the s_lastcheck field. |
56 | ||
c05b5521 TT |
57 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
58 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
59 | directories correctly because the change modified the layout of struct | |
60 | dirent to be incompatible with the libe2p shared library. | |
61 | ||
b90b826b TT |
62 | Cleaned up the mke2fs manual page and included a discussion about why |
63 | it's good to periodically check the filesystem even when journaling is | |
64 | enabled. | |
65 | ||
767de097 TT |
66 | Programmer's notes: |
67 | ------------------- | |
68 | ||
69 | Fix general gcc -Wall complaints. | |
70 | ||
71 | The types needed by the ext2 header files are now provided by | |
72 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
73 | ||
c05b5521 | 74 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
75 | in ext2_types.h. Also, if linux/types.h has already been defined, |
76 | don't try to redefine the types. | |
c05b5521 | 77 | |
767de097 TT |
78 | Fixed make depend script so that it automatically corrects the |
79 | pathname cleanups performed by make -M, so I don't have to fix them up | |
80 | by hand. | |
81 | ||
82 | Fixed the d_loaddump test case to be more robust, and not depend on | |
83 | bash'isms. | |
84 | ||
85 | Removed debugfs's dependence on pread(), which was accidentally | |
86 | intrudced in e2fsprogs 1.20 | |
87 | ||
c05b5521 TT |
88 | Fixed a performance bug in the libext2fs's icount routine; the size |
89 | estimate of the icount array was incorrectly being calculated. | |
90 | ||
b90b826b TT |
91 | Removed use of the badblocks compatibility functions in the e2fsprogs |
92 | programs. | |
93 | ||
94 | Added paranoia code which protects against strange cases where /etc | |
95 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
96 | ||
97 | The header file ext2_types.h is now installed. | |
98 | ||
99 | Autoconf is used to determine when we are on big-endian machines, | |
100 | instead of doing run-time tests, to save a few bytes of code. | |
101 | ||
102 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
103 | functions are no longer inline functions, which saves space and | |
104 | doesn't really cost any real performance. | |
105 | ||
106 | The ext2fs library no longer depends on the e2p library. (What need | |
107 | there was of it --- namely, fsetflags, was coded in-line). | |
108 | ||
109 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
110 | when the user is stupid and tries compiling the package using "make | |
111 | install" as root. | |
112 | ||
113 | Miscellaneous code cleanups: | |
114 | * Added missing files from Makefile.in's SRCS file, so that | |
115 | their dependencies would be properly calculated. | |
116 | * Removed redundant code | |
117 | * Fixed comments in code | |
118 | * Removed no-longer unneeded argsused #pragma. | |

5a009bb9 | 121 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 122 | ============================= |
5570a65a | 123 | |
31d1d0c8 TT |
124 | Add support for replaying the ext3 journal purely in user mode, |
125 | including handling the orphaned inode list. Used code contributed by | |
126 | Andreas Dilger, with bug fixes and the orphaned inode handling done | |
127 | by Theodore Ts'o. | |
128 | ||
129 | The mke2fs and tune2fs programs can create or modify a filesystem to | |
130 | include an ext3 journal. Tune2fs also can be used to remove an ext3 | |
131 | journal from a filesystem. | |
5570a65a TT |
132 | |
133 | E2fsck will now check for the existence of a linked list of orphan | |
134 | inodes in the superblock, and clear those inodes before starting the | |
135 | rest of the filesystem check (but after the journal playback). | |
136 | ||
31d1d0c8 TT |
137 | E2fsck now validates the file descriptor passed to the -C option, |
138 | which saves against the completion bar getting written to an | |
139 | unexpected location, such as the disk being checked. (Debian | |
140 | bug/wishlist #55220) | |
141 | ||
142 | E2fsck will now bump the filesystem revision number from zero to one | |
143 | if any of the compatibility bits are set. | |
144 | ||
145 | Fixed a bug where a badly corrupted directory on a big endian system | |
146 | could cause e2fsck to die with a bus error. The | |
147 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | |
148 | the ext2 library now does alignment sanity checks on the rec_len field | |
149 | of the directory entry before using it. | |
150 | ||
151 | The ext2 library has been enhanced to make tune2fs safe to run on | |
152 | mounted filesystems. (Users could usually get away with using tune2fs | |
153 | on mounted filesystems before, but with the advent of ext3 and | |
154 | journaling, it became important to make tune2fs was *really* safe for | |
155 | use even when the filesystem being modified is mounted.) E2label is | |
156 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | |
157 | is also now safe for use on mounted filesystems. | |
158 | ||
159 | Added a new program, e2image, which creates a backup of critical ext2 | |
160 | filesystem data structures. The generated image file can be examined | |
161 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use | |
162 | the image file to help recover very badly damaged filesystems. | |
163 | ||
164 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | |
165 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being | |
166 | large file when deciding whether or not the filesystem has large files. | |
167 | ||
168 | Fixed lsattr and chattr so that they work correctly on large files. | |
169 | (Fixes Debian bug #72690.) | |
170 | ||
171 | Removed limitation in get_device_size() which imposed a one terrabyte | |
172 | filesystem limitation. (Most 2.2 kernels still have a signed int | |
173 | problem which cause 1 TB block device limitation. Fortunately, the | |
174 | kernel patches to fix this are much easier than fixing the 2TB | |
175 | limitation in the kernel. :-) | |
176 | ||
177 | A max_mount_count of zero is now treated as if no mount count were | |
178 | set. (Previously, no mount count was indicated by using -1, and a | |
179 | mount count of zero caused e2fsck to always be run.) | |
180 | ||
77648565 | 181 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
182 | |
183 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | |
184 | filesystems won't be all checked at the same time under normal | |
185 | operations. | |
186 | ||
5570a65a TT |
187 | Fixed bug in the progress bar printing code which could cause e2fsck |
188 | to core dump on an illegal filesystem. | |
189 | ||
31d1d0c8 TT |
190 | Fixed bug in fsck which could allow more than one instance of e2fsck |
191 | to be printing a progress bar. (Debian bug #65267) | |
192 | ||
5570a65a TT |
193 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
194 | compiled into the kernel and not mounted. If the pathnames in | |
195 | /proc/partitions are incorrect, fsck will search /dev for the correct | |
196 | device (using the new ext2fs_find_block_device library function). | |
197 | Fsck now also checks the RAID devices first so that they are properly | |
31d1d0c8 TT |
198 | found when they are in use. Support has also been added to support |
199 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) | |
200 | ||
201 | Fixed a bug in fsck which caused it not deal properly with 16 | |
202 | byte long filesystem labels. | |
5570a65a | 203 | |
5a009bb9 TT |
204 | Fsck's -t option has been made a lot more flexible. The semantics for |
205 | what happens if a comma-separated list to fsck has been regularized, | |
206 | and it is now possible to filter what filesystems will get checked | |
207 | based what is in the filesystem's fstab entry's option field. (Debian | |
208 | bug #89483.) | |
209 | ||
5570a65a TT |
210 | The dumpe2fs program can now print out the group description |
211 | information in hex, and also prints the location of the superblock and | |
212 | block group descriptor for those block groups that have them. | |
213 | ||
214 | Mke2fs now clears the ext2 superblock before it starts creating a | |
215 | filesystem, so that the superblock magic number is only written if the | |
216 | filesystem creation process successfully completes. | |
217 | ||
218 | The debugfs program's stat command now pretty-prints the blocks used | |
219 | by an inode so that it's more compact and informative. | |
220 | ||
221 | The debugfs stats command now uses the same libe2p code (which is used | |
222 | by dumpe2fs) to print the superblock header information. This is more | |
223 | complete, and it avoids a bit of code duplication. | |
224 | ||
225 | Added a new debugfs command, set_super_value (ssv) which allows the | |
226 | user to set arbitrary superblock fields. | |
227 | ||
31d1d0c8 TT |
228 | Debugfs was extended to support inode numbers in hex (by prefixing |
229 | them with 0x), and so that modify_inode can set the inode generation | |
230 | number. Also, there is now a new function command called logdump | |
231 | which will dump an ext3 journal. | |
232 | ||
233 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | |
234 | debugfs. | |
235 | ||
236 | Debugfs's dump command now stops immediately upon reporting a disk | |
237 | read error. (Fixed a bug in ext2fs_file_read library routine which | |
238 | caused debugfs not to stop.) (Debian bug #79163) | |
239 | ||
240 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | |
241 | checked before /etc/mtab is used, since /proc/mounts is more likely to | |
242 | be accurate. | |
243 | ||
244 | Added portability fixes for Solaris and Linux/ia64. | |
245 | ||
246 | Various manual pages were clarified and cleaned up. (Fixed debian | |
247 | bugs #63442, #67446, and #87216) | |
248 | ||
5570a65a TT |
249 | |
250 | Programmer's notes: | |
251 | ------------------- | |
252 | ||
253 | The e2fsck message printer now supports %Iu and %Ig, which will print | |
254 | out the inode's user and group owners, respectively. | |
255 | ||
31d1d0c8 TT |
256 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
257 | that no longer dependent on the system having the correct version of | |
258 | the kernel header files. | |
259 | ||
5570a65a TT |
260 | Added a new function to libext2, ext2fs_find_block_device(), which |
261 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | |
262 | device given its device number. | |
263 | ||
31d1d0c8 TT |
264 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
265 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | |
266 | ioctls (and usually failing to define them since the system header | |
267 | files don't usually do this for us, and we're trying to avoid usage of | |
268 | kernel include files now). | |
269 | ||
5570a65a TT |
270 | Added new utility programs in tests/progs: random_exercise and |
271 | hold_inode. They aren't built by default; they're useful for | |
272 | exercising ext3 filesystem code. | |
273 | ||
31d1d0c8 TT |
274 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
275 | the filesystem close functions to only update the superblock, and to | |
276 | not touch the block group descriptors. Needed by tune2fs when | |
277 | modifying a mounted filesystem. | |
278 | ||
279 | Got rid of struct ext2fs_sb and replaced it with the standard struct | |
280 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break | |
281 | source (but not binary) compatibility of some users of the ext2 | |
282 | library. Those applications should just simply do a global search and | |
7d614e3d TT |
283 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
284 | the new header file <ext2fs/ext2_fs.h> which defines it. | |
31d1d0c8 TT |
285 | |
286 | The ino_t type has been renamed ext2_ino_t to protect applications | |
287 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | |
288 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an | |
289 | unexpected ABI change. | |
290 | ||
291 | The Makefiles have been reworked so that "make check" can be run from | |
292 | the top-level Makefile. | |
293 | ||
294 | Fix general gcc -Wall complaints and removed dead code. | |
295 | ||
296 | Remove use of NOARGS, because we assume everyone does ANSI C these | |
297 | days. | |
298 | ||
299 | Added build-rpm script from sct. | |
300 | ||
301 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added | |
302 | to support e2image. | |
303 | ||
304 | New function ext2fs_flush_icache which must be called if the | |
305 | application program modifies the inode table blocks without going | |
306 | through ext2fs_write_inode() interface. | |
307 | ||
308 | New ext2fs_check_mount_point() function, which will return the mount | |
309 | point of a device if mounted. | |
310 | ||
311 | The io_channel abstraction now has an optional interface, | |
312 | io_channel_write_range, which allows specific byte ranges to be | |
313 | written. | |
314 | ||
315 | The unix_io IO channel now supports write-through caching, so that | |
316 | journal creation is more efficient. | |
317 | ||
318 | Added x86 assembly language routines to support byte swapping, to | |
319 | reduce executable size. | |
320 | ||
321 | Fixed bug in the utility program subst so that it's possible to | |
322 | replace a substitution variable with a zero-length string. | |
323 | ||
324 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | |
325 | slipped into some of the problem number. | |
5570a65a | 326 | |
b777e26e TT |
327 | E2fsprogs 1.19 (July 13, 2000) |
328 | ============================== | |
ab146766 TT |
329 | |
330 | Release the resize2fs program since the timeout before it could | |
006ea71e | 331 | be released under the GPL has finally expired. |
ab146766 TT |
332 | |
333 | Add experimental support needed for the ext2 compression patches. | |
334 | This requires compiling e2fsprogs with the --enable-compression flag | |
335 | to the configure script. | |
336 | ||
337 | Added ext3 journalling support. E2fsck will run the journal (if | |
338 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is | |
339 | installed as a symlink to e2fsck. Fsck has been taught about ext3, | |
340 | and treats it the same as ext2 in terms of the progress bar logic. | |
341 | Dumpe2fs will display the superblock journaling information if the | |
342 | filesystem has a journal. The ext2 library will now permit opening an | |
343 | ext3 filesystem with the recovery flag set. This is necessary for | |
344 | on-line dump's to work correctly, but there may be issues with this | |
345 | working well since ext3 is much less agressive about syncing blocks to | |
346 | the filesystem, since they're safe on the journal. | |
347 | ||
348 | Tune2fs and e2fsck have been changed to allow the mount_count check to | |
349 | be disabled by setting max_mount_count to -1. (This was already | |
350 | supported by the kernel.) | |
351 | ||
352 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | |
353 | are used for ext3 as well. | |
354 | ||
355 | Added internationalization support for e2fsprogs; must be enabled | |
356 | by passing --enable-nls to configure. | |
357 | ||
358 | Always use the provided ext2fs header files to insulate ourselves from | |
359 | kernel version changes. Which include files are used by e2fsprogs | |
360 | have also been cleaned up to improve portability. | |
361 | ||
362 | Limit the number of times that e2fsck updates the progress bar so that | |
363 | people who are booting using a 9600 baud console don't get swampped by | |
364 | too many updates. | |
365 | ||
366 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | |
367 | much, much faster for large filesystems with a large number of | |
368 | directories. | |
369 | ||
370 | The memory footprint for e2fsck is now slightly smaller than before. | |
371 | ||
372 | E2fsck now checks if special devices have a non-zero size, and offers | |
373 | to clear the size field if it finds such an inode. | |
374 | ||
375 | E2fsck now checks if special devices have the append-only flag set, | |
376 | and offers to clear the inode. | |
377 | ||
378 | E2fsck now properly handles some "should never fail" cases during a | |
379 | bitmap copy in pass5. | |
380 | ||
381 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | |
382 | ||
31d1d0c8 TT |
383 | E2fsck now calculates the correct location of the backup superblock in |
384 | the case of filesystem blocksizes > 1k. | |
385 | ||
386 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | |
387 | which normally didn't cause problems under most filesystem parameters, | |
388 | but could cause a valid superblock to be rejected in extreme cases. | |
389 | Other checks for validating superblock values were made more | |
390 | stringent. | |
391 | ||
ab146766 TT |
392 | Added non-destructive write testing to the badblocks program, courtesy |
393 | of David Beattie. The badblocks also now has an option to input the | |
394 | current set of bad blocks, so that known bad blocks are skipped to | |
395 | speed up the badblocks test. There is also a persistent rescan | |
006ea71e TT |
396 | feature which causes badblocks to run until it has completed some |
397 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
398 | |
399 | Badblocks now checks to see if the device is mounted and refuses to do | |
400 | the tests involving writing to the device if it is mounted. Also, | |
401 | badblocks now allows the number of blocks to be checked to be | |
402 | defaulted to the size of the partition. | |
403 | ||
404 | Fixed a bug in fsck which didn't allow non-root users to be able to | |
405 | check filesystems if there were any LABEL= or UUID= entries in | |
406 | /etc/fstab. | |
407 | ||
408 | The Hurd doesn't support the filetype filesystem feature. The mke2fs | |
409 | program now makes sure that for the Hurd, the filestype feature is | |
410 | turned off. E2fsck will check to see if the filetype feature is | |
411 | turned on for Hurd filesystems, and offer to turn off the feature. | |
412 | ||
413 | Mke2fs now has a safety check to make sure the number of blocks do not | |
414 | exceed 32 bits even on a 64 bit platform. | |
415 | ||
416 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | |
417 | fsck's. (For those people who like to do interactive fsck's in the | |
418 | /etc/rc scripts!?!) | |
419 | ||
420 | Debugfs has a few new features: the rdump command, which will do a | |
421 | recursive dump of a directory and all of its contents, and the lcd | |
422 | command which does a local chdir (much like the ftp command of the | |
423 | same name). In addition, the debugfs program and the open_filesystem | |
424 | command now takes three new options: -b and -s, which allows the | |
425 | blocksize and superblock location to be specified, and the -c option | |
426 | which is used in catastrophic situations where the block group | |
427 | descriptors are corrupt. If the -c option is specified, debugfs will | |
428 | skip trying to read in the block and inode bitmaps. | |
429 | ||
430 | Debufs's lsdel command was fixed to handle bad blocks in the inode | |
431 | table. | |
432 | ||
433 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | |
434 | 4 digit years. | |
435 | ||
436 | General improvements in error messages | |
437 | ||
438 | - Mke2fs prints a sane error message if the partition size is zero | |
439 | (usually because the partition table wasn't reread by the | |
440 | kernel due to the partition being busy), instead of "invalid | |
441 | argument passed to ext2 library while initializing superblock". | |
442 | ||
443 | - Fsck now prints more self-explanatory message if an invalid UUID= | |
444 | or LABEL= specification is passed to it. | |
445 | ||
446 | UUID library changed to use the LGPL. | |
447 | ||
448 | Fixed a bug in the UUID library where very rapid calls to the | |
449 | time-based UUID generator could cause duplicate UUID's to be returned. | |
450 | This was not a problem for e2fsprogs, but it could be a problem for | |
451 | other users of the library. | |
452 | ||
453 | Make the UUID library more robust in the face of missing or an | |
454 | improper /dev/urandom or /dev/random files. | |
455 | ||
456 | Added some random portability fixes for Solaris. | |
457 | ||
458 | Some minor man page updates. | |
459 | ||
460 | Fixed a memory leak in the ss library. | |
461 | ||
462 | ||
463 | Programmer's notes: | |
464 | ------------------- | |
465 | ||
466 | We now try to use lseek64 and open64 from the LFS if possible. | |
467 | ||
468 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | |
469 | a boolean option. | |
470 | ||
471 | The mark and unmark bitmap functions now return the previous state of | |
472 | the bit that was being changed, which is useful for some speed | |
473 | optimizations. | |
474 | ||
475 | The following functions have been added to enhance the badblocks list | |
476 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | |
477 | ext2fs_badblocks_equal. | |
478 | ||
479 | The ext2 header files now have the latest journalling fields to the | |
480 | superblock. | |
481 | ||
482 | The ext2fs_mkdir function in libext2fs now properly backs out of error | |
483 | conditions robustly. | |
484 | ||
485 | Cleaned up makefiles: | |
486 | - to cleanly compile with the -j flag. | |
487 | - so distclean removes all generated files. | |
488 | - so in case of an error while installing header files, the make aborts. | |
489 | ||
490 | Fix test_script so that it works correctly when compiling in the | |
491 | source directory. | |
492 | ||
31d1d0c8 TT |
493 | The random UUID generation routine has been made slightly better in |
494 | the case where /dev/random doesn't exist. (Use of randomly-based UUID | |
495 | is still not recommended if /dev/random doesn't exist, however; it's | |
496 | better to use the time/ethernet MAC address UUID in this case.) | |
ab146766 TT |
497 | |
498 | Clean up the build process so it's more friendly in case of missing | |
499 | directories. | |
500 | ||
501 | The ext2fs header file can now be #include'd into C++ programs. | |
502 | ||
503 | The e2p.h header file is now installed. | |
504 | ||
505 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | |
506 | ||
507 | ||
508 | ||
24ded091 TT |
509 | E2fsprogs 1.18 (November 10, 1999) |
510 | ================================== | |
511 | ||
512 | Fix a core dumping bug in e2fsck if an imagic inode is present or | |
513 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | |
514 | has to restart pass 1 processing. E2fsck now closes the filesystem | |
515 | before freeing a large number of its data structures, so in the case | |
516 | of future memory faults, at least the fixed filesystem will be fully | |
517 | written out. | |
518 | ||
519 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | |
520 | imagic inode, it will offer to clear the imagic flag. | |
521 | ||
522 | E2fsck will now offer to clear the immutable flag on special files | |
523 | (device/socket/fifos) when running it in non-preen mode. | |
524 | ||
525 | E2fsck will now set the filetype when creating /lost+found, and when | |
526 | connected orphaned inodes to /lost+found. | |
527 | ||
528 | Debugfs's ncheck and icheck commands now handles the case where there | |
529 | are bad blocks in the inode table without bombing out. | |
530 | ||
531 | The badblocks list processing code has been made more efficiently for | |
532 | appending a large number of (ordered) badblocks to the badblocks list. | |
533 | ||
534 | Some minor man page updates. | |
535 | ||
536 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | |
537 | mode, but some people like to do this in boot scripts for silly reasons). | |
538 | ||
539 | Programmer's notes: | |
540 | ------------------- | |
541 | ||
542 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | |
543 | with the problem code convention. | |
544 | ||
545 | The badblocks list regression test program has been updated to work | |
546 | with previously made API name changes. | |
547 | ||
548 | The ext2fs_free() command now uses the new badblocks API to avoid | |
549 | using the compatibility layer. | |
550 | ||
551 | Added new regression test cases; the run_e2fsck test script now | |
552 | supports the ability for a test case to run a prepratory command | |
553 | before running e2fsck. | |
554 | ||
28e1194e TT |
555 | E2fsprogs 1.17 (October 26, 1999) |
556 | ================================= | |
557 | ||
558 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | |
559 | infinite loop. | |
560 | ||
561 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | |
562 | thus potentially causing problems if a binary UUID contained a NULL | |
563 | character. | |
564 | ||
565 | E2fsck now uses stricter checks for directory entries in pass 2: | |
566 | zero-length filenames are not allowed; neither are 8 byte long | |
567 | directory entries. | |
568 | ||
569 | The debugfs "dirty" command now clears the filesystem valid bit. | |
570 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | |
571 | bit in the in-core superblock image. The new functionality is more | |
572 | what the user expects, and is more useful.) | |
573 | ||
574 | Added a debugging hook to test parallel fsck; if the environment | |
575 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | |
576 | will be checked in parallel when they normally would not be. | |
577 | ||
578 | Programmer's notes: | |
579 | ------------------- | |
580 | ||
581 | Fixed some #ifdef's for compilation under the Hurd OS. | |
582 | ||
583 | Fixed minor W2K compatibility problems. | |
584 | ||
585 | Fixed some miscellaneous GCC warnings. | |
586 | ||
587 | ||
8a31ffef TT |
588 | E2fsprogs 1.16 (October 22, 1999) |
589 | ================================= | |
590 | ||
591 | Fixed a race condition bug in fsck; when printing a progress bar, if | |
592 | checking multiple filesystems in parallel, it was possible for fsck to | |
593 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | |
594 | handler, which would cause it to terminate with a signal 10. | |
595 | ||
596 | E2fsck now properly handles filesystems that have the | |
597 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a | |
598 | filesystem into using or not using FILETYPE feature. | |
599 | ||
600 | E2fsck now properly handles filesystems that have the IMAGIC feature | |
601 | turned on (this is used on Linux AFS servers). | |
602 | ||
603 | The mke2fs program now creates filesystems that have the filetype and | |
604 | sparse_superblock features enabled by default, unless it is run on a | |
605 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, | |
606 | so there is now a new flag -O which allows the user to specify with | |
607 | which features she would like to create the filesystem; "mke2fs -O | |
608 | none" will create a filesystsem compatible with 2.0 kernels. | |
609 | ||
610 | The tune2fs program now has a -O option which allows the user to set | |
611 | and reset "safe" filesystem features. Currently, the only ones which | |
612 | allows to be modified are the filetype and sparse_superblock features. | |
613 | Note setting or clearing either feature will require running e2fsck on | |
614 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature | |
615 | requires that there is enough free space on the filesystem for the | |
616 | extra superblocks which will be created by e2fsck.) | |
617 | ||
618 | Debugfs can now set and print filesystem features in the superblock | |
619 | using the "features" command. Dumpe2fs will print out the complete | |
620 | set of features when listing the superblock. | |
621 | ||
622 | Dumpe2fs has new options -f (force) and -h (header-only). | |
623 | ||
624 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | |
625 | message to come up. This could happen when decrementing or | |
626 | incrementing a link count could result in an overflow. | |
627 | ||
628 | Fixed a bug in e2fsck where the block count on the lost+found | |
629 | directory would not be properly incremented when the directory was | |
630 | expanded to the point where an indirect block needed to be allocated. | |
631 | ||
632 | E2fsck now makes some additional sanity checks on the superblock to | |
633 | avoid crashing or giving a memory allocation error if some of the | |
634 | values in the superblock are unresonable (but the superblock otherwise | |
635 | looks valid). | |
636 | ||
637 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | |
638 | require two passes to completely fix the filesystem. This happened if | |
639 | an inode claimed blocks that was part of the filesystem metadata | |
640 | (typically, when garbage was written into an inode table or indirect | |
641 | block, since this kind of filesystem corruption normally doesn't | |
642 | happen otherwise). | |
643 | ||
644 | On the Alpha, glibc declares st_flags although it isn't actually used; | |
645 | the configure script was improved to detect this case so that | |
646 | e2fsprogs can avoid using the non-functional stat field. | |
647 | ||
648 | The manual pages were updated to use a more consistent formatting | |
649 | style consistent with standard Unix man pages. Mke2fs's man page | |
650 | added documentation for a few previously undocumented options. | |
651 | ||
652 | Fixed minor display bugs in tune2fs and mke2fs. | |
653 | ||
654 | Programmer's notes: | |
655 | ------------------- | |
656 | ||
657 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | |
658 | ||
659 | Added features to parse and print feature strings into the e2p library. | |
660 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | |
661 | ||
662 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | |
663 | whose directory entries contain proper filetype information if the | |
664 | filesystem supports it. | |
665 | ||
666 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | |
667 | the directory entry filetype information. This is used to set the | |
668 | directory entry filetype information if the filesystem supports it. | |
669 | ||
670 | Fixed a bug in ext2fs_expand_dir() where the block count in a | |
671 | directory's inode would not be properly incremented when the directory | |
672 | was expanded to the point where an indirect block needed to be | |
673 | allocated. | |
674 | ||
675 | ||
a39f3efe | 676 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 677 | ============================== |
6d53db3f TT |
678 | |
679 | Add configuration checks so that e2fsprogs will compile cleanly on | |
680 | Linux 2.3 kernels that have renamed i_version to i_generation. | |
681 | ||
e2a99be6 TT |
682 | E2fsck now prints a progress/completion bar (and not just a simple |
683 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | |
684 | signal. Fsck will automatically manage the (potentially muliple) | |
685 | e2fsck processes to print completion bars if it is given a -C option, | |
686 | with the right thing happening if multiple filesystems are being | |
687 | checked in parallel. | |
688 | ||
689 | Mke2fs now has better automatic hueristics to determine the filesystem | |
690 | parameters to be used for a particular filesystem. Added a new option | |
691 | -T which allows the user to specify how the filesystem is to be used, | |
692 | which helps mke2fs do a better job selecting the filesystem parameters. | |
693 | ||
a39f3efe TT |
694 | Mke2fs now creates revision 1 filesystems by default, and with the |
695 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
696 | not understood by Linux 2.0 kernels, so they will only allow read-only |
697 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 698 | |
6d53db3f TT |
699 | Fix bug where if /dev/null couldn't be opened (should never happen), |
700 | e2fsck would hang in a tight loop. | |
701 | ||
702 | Make e2fsck handle the case where /lost+found isn't a directory. | |
703 | ||
704 | E2fsck now uses mallinfo if it exists to get accurate statistics about | |
705 | its memory usage. | |
706 | ||
707 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | |
708 | inode had any problems before connecting it to /lost+found. | |
709 | ||
710 | Add check to e2fsck so it makes sure that total number of inodes in | |
711 | the filesystem is a sane number. | |
712 | ||
713 | Fix fencepost error when clearing an the end of the block bitmap which | |
714 | caused the last block in the bitmap not to get cleared. | |
715 | ||
716 | Cleaned up a number of messages in e2fsck: | |
717 | * The message "Group's #'s copy of the group descriptor..." | |
718 | was fixed so that the correct number would be displayed. | |
719 | * Added missing space in the "disk write-protected" error messsage | |
720 | * Cleaned up the error message printed when a non-interactive | |
721 | e2fsck needs to abort a check because the filesystem | |
722 | appears to be mounted. | |
723 | ||
724 | Added a new command-line utility, uuidgen, which will create and print | |
725 | a UUID. | |
726 | ||
727 | Make debugfs's icheck command more robust by checking to make sure an | |
728 | inode has valid blocks before interarting over the inode's blocks. | |
729 | ||
730 | UUID generation now uses a random-based scheme whenever possible to | |
731 | prevent potential privacy problems. | |
732 | ||
733 | Man pages for all of the UUID functions in the lirbary were added. | |
734 | ||
735 | Fixed bug in fsck so it won't coredump if a filesystem not in | |
736 | /etc/fstab is given to it. | |
737 | ||
738 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | |
739 | that most of the other mount utilities understands. | |
740 | ||
741 | Mke2fs will make a filesystem even if it appears mounted if the force | |
742 | option is given. | |
743 | ||
744 | Dumpe2fs has new command-line options which allow a filesystem expert | |
745 | to specify the superblock and blocksize when opening a filesystem. | |
746 | This is mainly useful when examining the remains of a toasted | |
747 | filesystem. | |
748 | ||
749 | The badblocks program has been updated to display correctly on disks | |
750 | with large block numbers. | |
751 | ||
e2a99be6 TT |
752 | The badblocks program no longer gives spurious errors when errors |
753 | occur on non-block boundaries, which is common if the blocksize is | |
754 | larger than 1k. | |
755 | ||
6d53db3f TT |
756 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
757 | MKE2FS_SYNC environment variable is set. This is to work around a VM | |
758 | bug in the 2.0 kernel. I've heard a report that a RAID user was able | |
a39f3efe TT |
759 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
760 | needed for most Linux 2.2 users. | |
6d53db3f TT |
761 | |
762 | Fixed miscellaneous documentation and man pages. | |
763 | ||
764 | Programmer's notes: | |
765 | ------------------- | |
766 | ||
767 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | |
768 | in e2fsck's pass1.c really should have been static. | |
769 | ||
770 | The return value of the uuid_compare() function was changed to make it | |
771 | match with the convetions used by strcmp, memcmp, and Paul Leach's | |
772 | UUID sample document. | |
773 | ||
774 | The "make depend" process has now been made more automated; it now | |
775 | automatically word-wraps the dependencies, and only replaces source | |
776 | Makefile.in if there has been a change in the dependencies. Also, a | |
777 | top-level "make depend" now recurses through all the subdirectories | |
778 | automatically. | |
779 | ||
780 | The Makefile in .../util has been changed so that subst is built using | |
781 | the native C compiler during a cross-compilation, since the subst | |
782 | program is only used during the build process. Also add an explicit | |
783 | rule to build util/subst by cd'ing to the correct directory and | |
784 | running Makefile. | |
785 | ||
786 | The man directories are defined in terms mandir, so that the configure | |
787 | script can override the location of the manual pages. | |
788 | ||
789 | The config files have been updated to recognize new machine types for | |
790 | both the i386 and alpha families. | |
791 | ||
792 | Fsck has been modified so that it will accurately create an | |
793 | fsck_instance even when the noexecute flag is set. This allows for | |
794 | accurate debugging of the fsck pass structure. Also, when the verbose | |
795 | flag is given twice, fsck will print debugging information about when | |
796 | fsck is waiting for jobs to finish. | |
797 | ||
798 | ||
14790ed7 TT |
799 | E2fsprogs 1.14 (January 9, 1999) |
800 | ================================ | |
801 | ||
802 | Fix the fstab parsing code so that it can handle blank lines and | |
803 | comment characters. Also, missing pass numbers need to be treated as | |
804 | zero. | |
805 | ||
806 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | |
807 | needs to restart processing after fixing an egregious inconsistency) | |
808 | it would try to access already freed memory. | |
809 | ||
810 | E2fsck now prints non-printable characters in directory entries and | |
811 | pathnames using '^' and 'M-' notation. | |
812 | ||
813 | Fixed chattr so that it will ignore symbolic links when doing | |
814 | recursive descent traversals. For both chattr and lsattr, no longer | |
815 | print the version string unless the -V option is given. | |
816 | ||
817 | Allow the system administrator to directly specify the number of | |
818 | inodes desired in the filesystem, for some special cases where this is | |
819 | necessary. | |
820 | ||
821 | Fix portability problems so that e2fsprogs can be compiled under Linux | |
822 | 1.2 systems and Solaris systems. | |
823 | ||
824 | Update the config.guess file with a more recent version that will | |
825 | identify newer Linux platforms. | |
826 | ||
827 | Programmer's notes | |
828 | ------------------ | |
829 | ||
830 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | |
831 | an inode number of zero is passed to them. | |
832 | ||
556ad132 TT |
833 | E2fsprogs 1.13 (December 15, 1998) |
834 | ================================== | |
835 | ||
836 | Fixed a bug in debugfs where an error messages weren't getting printed | |
837 | when the ext2 library routines to read inodes returned errors in the | |
838 | stat, cmri and rm commands. | |
839 | ||
840 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | |
841 | provided, it won't create an inode table smaller than the minimum | |
842 | number of inodes required for a proper ext2 filesystem. | |
843 | ||
844 | Fsck now parses the /etc/fstab file directly (instead of using | |
845 | getmntent()), so that it can distinguish between a missing pass number | |
846 | field and pass number field of zero. This caused problems for | |
847 | diskless workstations where all of the filesystems in /etc/fstab have | |
848 | an explicit pass number of zero, and fsck could not distinguish this | |
849 | from a /etc/fstab file with missing pass numbers. | |
850 | ||
851 | E2fsck will create a /lost+found directory if there isn't one in the | |
852 | filesystem, since it's safer to create the lost+found directory before | |
853 | it's needed. | |
854 | ||
855 | Fixed e2fsck so that it would detect bogus immutable inodes which | |
856 | happen to be sockets and FIFO files, and offer to clear them. | |
857 | ||
858 | If a filesystem has multiple reasons why it needs to be checked, and | |
859 | one of the reasons is that it is uncleanly mounted, e2fsck will print | |
860 | that as the reason why the filesystem is being checked. | |
861 | ||
862 | Cleaned up the output routines of mke2fs so that it doesn't overflow | |
863 | an 80 column display when formating really big filesystems. | |
864 | ||
865 | Added a sanity check to e2fsck to make sure that file descriptors 0, | |
866 | 1, 2 are open before opening the hard disk. This avoids a problem | |
867 | where a broken program might exec e2fsck with those file descriptors | |
868 | closed, which would cause disastrous results if the kernel returns a | |
869 | file descriptor for the block device which is also used by FILE * | |
870 | stdout. | |
871 | ||
872 | Fixed up the e2fsck progress reporting functions so that the values | |
873 | reliably reach 100% at the completion of all of the e2fsck passes. | |
874 | ||
875 | Fixed minor documentation bugs in man pages and usage messages. | |
876 | ||
877 | Programmer's notes: | |
878 | ------------------- | |
879 | ||
880 | Fixed a number of lint warnings in the ext2fs library and potential | |
881 | portability problems from other OS's header files that might define | |
882 | CPP macros for names like "max" and "min". | |
883 | ||
884 | ext2fs_badblocks_list_add() has been made more efficient when it needs | |
885 | to grow the bad blocks list. | |
886 | ||
887 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | |
888 | just before exiting. | |
889 | ||
890 | Fixed the substition process for generating the mk_cmds and compile_et | |
891 | scripts so that they will work outside of the build tree. | |
892 | ||
893 | Add sanity check to e2fsck so that if an internal routine | |
894 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | |
895 | and causing a core dump. This should never happen, but... | |
896 | ||
a569671a | 897 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
898 | ================================== |
899 | ||
900 | E2fsprogs now works with glibc (at least with the version shipped wtih | |
901 | RedHat 5.0). The ext2fs_llseek() function should now work even with | |
902 | i386 ELF shared libraries and if llseek() is not present. We also | |
903 | explicitly do a configure test to see if (a) llseek is in libc, and | |
904 | (b) if llseek is declared in the system header files. (See standard | |
905 | complaints about libc developers don't understand the concept of | |
906 | compatibility with previous versions of libc.) | |
907 | ||
c9833a60 TT |
908 | The ext2fs library now writes out the block group number in each of |
909 | the superblock copies. This makes it easier to automatically | |
910 | determine the starting block group of the filesystem when the block | |
911 | group information is trashed. | |
912 | ||
913 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | |
101c84f2 TT |
914 | which means that e2fsprogs will ignore the high 8 bits of the |
915 | directory entry's name_len field, so that it can be used for other | |
916 | purposes. | |
917 | ||
918 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | |
919 | E2fsprogs will now support filesystems with 64-bit sized files. | |
920 | ||
921 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | |
922 | ||
21d53850 TT |
923 | Added new program "e2label", contributed by Andries Brouwer. E2label |
924 | provides an easy-to-use interface to modify the filesystem label. | |
925 | ||
a4b2d3ce TT |
926 | Fixed bug so that lsattr -v works instead of producing a core dump. |
927 | ||
21d53850 TT |
928 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
929 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
930 | |
931 | Mke2fs will check the size of the device, and if the user specifies a | |
932 | filesystem size larger than the apparent size of the device it will | |
933 | print a warning message and ask if the user wants to proceed. | |
934 | ||
c9833a60 TT |
935 | E2fsck has a new option -C, which sends completion information to the |
936 | specified file descriptor. For the most part, this is intended for | |
937 | programs to use, although -C 0 will print a spinning character to the | |
938 | stdout device, which may be useful for users who want to see something | |
939 | happening while e2fsck goes about its business. | |
940 | ||
21d53850 TT |
941 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
942 | expand the /lost+found directory, and sometimes the bitmaps haven't | |
943 | been merged in. Also fixed a related bug where ext2fs_write_dir_block | |
944 | was used to write out a non-directory block. (Which would be bad on a | |
945 | non-Intel platform with byte swapping going on.) | |
946 | ||
947 | Fixed bug in e2fsck where it would print a "programming error" message | |
948 | instead of correctly identifying where a bad block was in used when | |
949 | the bad block was in a non-primary superblock or block group | |
950 | descriptor. Also fixed a related bug when sparse superblocks are in | |
951 | use and there is a bad block where a superblock or block group | |
952 | descriptor would have been in a group that doesn't include a | |
953 | superblock. | |
954 | ||
955 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | |
956 | the block group descriptor table is corrupt, it was possible to try to | |
957 | allocate a huge array, fail, and then abort e2fsck. | |
958 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | |
959 | and subsitutes reasonable values if the descriptors are obviously bogus. | |
960 | ||
961 | If e2fsck finds a device file which has the immutable flag set and the | |
962 | i_blocks beyond the normal device number are non-zero, e2fsck will | |
963 | offer to remove it, since it's probably caused by garbage in the inode | |
964 | table. | |
965 | ||
966 | When opening a filesystem, e2fsck specially checks for the EROFS error | |
967 | code, and prints a specific error message to the user which is more | |
968 | user friendly. | |
969 | ||
970 | If the filesystem revision is too high, change the e2fsck to print | |
971 | that this is either because e2fsck is out of date, or because the | |
972 | superblock is corrupt. | |
973 | ||
974 | E2fsck now checks for directories that have duplicate '.' and '..' | |
975 | entries, and fixes this corruption. | |
976 | ||
977 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | |
978 | calls) at all times. The ext2fs_flush() function now performs a sync | |
979 | only if it needed to write data blocks to disk. | |
980 | ||
981 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | |
982 | certain errors would not be properly reported. | |
983 | ||
984 | Updated and expanded a few points in the man pages which users | |
985 | complained wheren't explicit enough. | |
986 | ||
987 | Added special case byte-swapping code if compiling on the PowerPC, to | |
988 | accomodate the strange big-endian variant of the ext2 filesystem that | |
989 | was previously used on the PowerPC port. | |
990 | ||
991 | ||
992 | Programmer's notes: | |
993 | ------------------- | |
994 | ||
995 | Removed C++ keywords from the ext2fs libraries so that it could be | |
996 | compiled with C++. | |
997 | ||
998 | E2fsck's internal organization has now been massively reorganized so | |
999 | that pass*.c don't have any printf statements. Instead, all problems | |
1000 | are reported through the fix_problem() abstraction interface. E2fsck | |
1001 | has also been revamped so that it can be called as a library from a | |
1002 | application. | |
1003 | ||
1004 | Added new fileio primitives in libext2fs for reading and writing | |
1005 | files on an unmounted ext2 filesystem. This interface is now used by | |
1006 | debugfs. | |
1007 | ||
1008 | Added a new libext2fs function for mapping logical block numbers of | |
1009 | a file to a physical block number. | |
1010 | ||
1011 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | |
1012 | a block, zeros it, and updates the filesystem accounting records | |
1013 | appropriately. | |
1014 | ||
1015 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | |
1016 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. | |
1017 | ||
1018 | The libext2fs functions now use a set of memory allocation wrapper | |
1019 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | |
1020 | instead of malloc, free, and resize. This makes it easier for us to | |
1021 | be ported to strange environments where malloc, et. al. aren't | |
1022 | necessarily available. | |
1023 | ||
1024 | Change the libext2fs fucntion to return ext2-specific error codes | |
1025 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | |
1026 | and depending on the existence of system error codes (such as EEXIST | |
1027 | and ENOENT). | |
1028 | ||
1029 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | |
1030 | files. | |
1031 | ||
1032 | Add protection against ext2_io.h and ext2fs.h being included multiple | |
1033 | times. | |
1034 | ||
1035 | The types used for memory lengths, etc. have been made more portable. | |
1036 | In generla, the code has been made 16-bit safe. Added Mark | |
1037 | Habersack's contributed DOS disk i/o routines. | |
1038 | ||
1039 | Miscellaneous portability fixes, including not depending on char's | |
1040 | being signed. | |
1041 | ||
1042 | The io_channel structure has a new element, app_data, which is | |
1043 | initialized by the ext2fs routines to contain a copy of the filesystem | |
1044 | handle. | |
1045 | ||
1046 | ext2fs_check_directory()'s callback function may now return the error | |
1047 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | |
1048 | really do the checking, despite the presence of the callback function. | |
1049 | ||
1050 | ||
bc210074 TT |
1051 | E2fsprosg 1.11 (June 17, 1997) |
1052 | ============================== | |
1053 | ||
1054 | Fixed e2fsck to detect (previously ignored) conflicts between the | |
1055 | superblock or block group descriptors and block bitmaps, inode | |
1056 | bitmaps, and inode tables. | |
1057 | ||
1058 | Fixed bug in e2fsck so that when the message printed out when a block | |
1059 | or inode bitmap conflicts with other data, it has the correct group | |
1060 | number. | |
1061 | ||
1062 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | |
1063 | to badblocks. This meant that not all of the filesystem was being | |
1064 | tested for bad blocks! | |
1065 | ||
1066 | Fixed an array boundary overrun case which cropped up in | |
1067 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c | |
1068 | -b 4096". | |
1069 | ||
1070 | Adjusted the number of columns printed by mke2fs when displaying the | |
1071 | superblock backups to avoid running over 80 columns when making a | |
21d53850 | 1072 | really big filesystem. |
bc210074 TT |
1073 | |
1074 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | |
1075 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | |
1076 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | |
1077 | ||
1078 | Programmer's notes: | |
1079 | ------------------- | |
1080 | ||
1081 | Fixed install rule in lib/ss so that ss_err.h is actually getting | |
1082 | installed. | |
1083 | ||
1084 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | |
1085 | bassed back to the caller. | |
1086 | ||
1087 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | |
1088 | setting the current inode number (which meant this function wasn't | |
1089 | working at all). | |
1090 | ||
1091 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | |
1092 | blocks in the bitmap when increasing the size of the bitmap. | |
1093 | ||
1094 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | |
1095 | to be more realistic. | |
1096 | ||
1097 | Added a new function ext2fs_allocate_group_table, which sets up the | |
1098 | group descriptor information (and allocates inode and block bitmaps, | |
1099 | and inode tables for a particular group). The function was created by | |
1100 | factoring out code form ext2fs_allocate_tables(). | |
1101 | ||
1102 | Added a new function ext2fs_move_blocks which takes a bitmap of the | |
1103 | blocks to be moved, and moves them to another location on the | |
1104 | boardboard. | |
1105 | ||
1106 | Make the unix_io channel's io_channel_flush implementation calls sync() | |
1107 | to to flush the kernel buffers to disk. | |
1108 | ||
1109 | Added a new function ext2fs_dblist_count returns the number of | |
1110 | directory blocks in dblist. | |
1111 | ||
1112 | ||
ae851482 TT |
1113 | E2fsprogs 1.10 (April 24, 1997) |
1114 | =============================== | |
1115 | ||
1116 | Mke2fs once again defaults to creating revision #0 filesystems, since | |
1117 | people were complaining about breaking compatibility with 1.2 kernels. | |
1118 | Warning messages were added to the mke2fs and tune2fs man pages that | |
1119 | the sparse superblock option isn't supported by most kernels yet (1.2 | |
1120 | and 2.0 both don't support parse superblocks.) | |
1121 | ||
1122 | Added new flag to mke2fs, -R <raid options>, which allows the user to | |
1123 | tell mke2fs about the RAID configuration of the filesystem. Currently | |
1124 | the only supported raid option is "stride" which specifies the width | |
1125 | of the RAID stripe. | |
1126 | ||
1127 | Fixed bug in e2fsck where pass1b would bomb out if there were any | |
1128 | blocks marked bad in the inode table. | |
1129 | ||
1130 | Fixed rare bug in mke2fs where if the user had a very unlucky number | |
1131 | of blocks in a filesystem (probability less than .002) the resulting | |
1132 | filesystem would be corrupt in the last block group. | |
1133 | ||
1134 | Fixed bug where if e2fsck tried to allocate a block to fix a | |
1135 | filesystem corruption problem and the filesystem had no free blocks, | |
1136 | ext2fs_new_block() would loop forever. | |
1137 | ||
1138 | The configure script now checks explicitly to see if "-static" works, | |
1139 | since that can't be assumed to be true --- RedHat doesn't install | |
1140 | libc-static by default. | |
1141 | ||
1142 | Fixed bug in libext2's block iterator functions where under some | |
1143 | cirmcustances, file with holes would cause the bcount parameter to the | |
1144 | callback function to be incorrect. This bug didn't affect any of | |
1145 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | |
1146 | author of the PPC boot loader. | |
1147 | ||
1148 | Removed use of static variables to store the inode cache in libext2fs. | |
1149 | This caused problems if more than one filesystem was accessed via | |
1150 | libext2fs (static variables in libraries are generally a bad idea). | |
1151 | Again, this didn't affect e2fsprogs programs, but it was discovered by | |
1152 | Paul Mackerras. | |
1153 | ||
1154 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | |
1155 | will compile cleanly with 1.2.13 kernels (even with a.out shared | |
1156 | libraries!) | |
1157 | ||
1158 | Programmer's notes: | |
1159 | ------------------- | |
1160 | ||
1161 | Added new functions to duplicate an ext2 filesystem handle, and its | |
1162 | associated substructure. New functions: ext2fs_dup_handle(), | |
1163 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | |
1164 | Other structures, such as the io_channel and the inode_cache, now have | |
1165 | a ref count so that they only get freed when they are no longer used | |
1166 | by any filesystem handle. (These functions were added as part of the | |
1167 | development effort for an ext2 resizer). | |
1168 | ||
2ecc6fef TT |
1169 | E2fsprogs 1.09 (April 14, 1997) |
1170 | =============================== | |
1171 | ||
1172 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | |
1173 | accidentally introduced in the 1.08 release. The overhead calculation | |
1174 | was accidentally removed, which caused ext2fs_initialize() to not | |
1175 | notice when the filesystem size needed to be adjusted down because | |
1176 | there wasn't enough space in the last block group. | |
1177 | ||
1178 | Fixed bug in version parsing library routine; it was always parsing | |
1179 | the library version string, instead of using the passed-in string. | |
1180 | ||
1181 | Clarified chattr man page. | |
1182 | ||
24757fa0 TT |
1183 | E2fsprogs 1.08 (April 10, 1997) |
1184 | =============================== | |
1185 | ||
1186 | E2fsck 1.07 was very slow when checking very large filesystems with a | |
1187 | lot of files that had hard links (i.e., news spools). This was fixed | |
1188 | by seriously revamping the icount abstraction. Added a formal test | |
1189 | suite for the icount abstraction. | |
1190 | ||
1191 | Debugfs now has a "-l" option to the "ls" command, which lists the | |
1192 | inode number, permissions, owner, group, size, and name of the files | |
1193 | in the directory. | |
1194 | ||
1195 | Fix a bug in e2fsck where when a directory had its blocks moved to | |
1196 | another location during the pass 1b processing, the directory block | |
1197 | list wasn't updated, so pass 2 wouldn't check (and correct) the | |
1198 | correct directory block. | |
1199 | ||
1200 | E2fsck will now treat inodes which contain blocks which are claimed by | |
1201 | the filesystem metadata by treating them as multiply claimed blocks. | |
1202 | This way, the data in those blocks can be copied to a new block during | |
1203 | the pass 1b--1d processing. | |
1204 | ||
1205 | E2fsck will attempt to determine the correct superblock number and | |
1206 | display it in the diagnostic and warning messages if possible. | |
1207 | ||
1208 | Add support for a new (incompatible) feature, "sparse_super". This | |
1209 | feature reduces the number of blocks which contain copies of backup | |
1210 | superblocks and block group descriptors. (It is only an incompatible | |
1211 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now | |
1212 | support a new -s option; e2fsck will recognize filesystems built with | |
1213 | this feature turned on. | |
1214 | ||
1215 | E2fsck now checks the library to make sure is the correct version, | |
1216 | using new library functions. (This helps to diagnose incorrectly | |
1217 | installed e2fsprogs distributions.) | |
1218 | ||
1219 | Dumpe2fs now prints more information; its now prints the the | |
1220 | filesystem revision number, the filesystem sparse_super feature (if | |
1221 | present), the block ranges for each block group, and the offset from | |
1222 | the beginning of the block group. | |
1223 | ||
1224 | Mke2fs now distributes the inode and block bitmap blok so that the | |
1225 | won't be concentrated in one or two disks in RAID/striping setups. | |
1226 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | |
1227 | choose the largest blocks per group that be chosen. (For 2k blocks, | |
1228 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | |
1229 | to 32768 blocks/group.) Previously mke2fs would not allow | |
1230 | specification of more than 8192 blocks per group, even if you were | |
1231 | using a 2k or 4k block group. | |
1232 | ||
1233 | Programmer's notes: | |
1234 | ------------------- | |
1235 | ||
1236 | Added a new function ext2fs_create_icount2() which takes a "hint" | |
1237 | argument. This hint argument presets the icount array with the list | |
1238 | of inodes which actually need to be in the icount array. This really | |
1239 | helps to speed up e2fsck. | |
1240 | ||
1241 | Added a new function ext2fs_icount_validate() which checks the rep | |
1242 | invariant for the icount structure. This is used mostly for testing. | |
1243 | ||
1244 | The error mesasage given when a bad inode number is passed to | |
1245 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | |
1246 | EXT2FS_UNMARK_ERROR). | |
1247 | ||
1248 | Added a new function ext2fs_set_dir_block which sets the block of a | |
1249 | dblist entry, given the directory inode and blockcnt. | |
1250 | ||
1251 | Added a new function ext2fs_get_library_version() which returns the | |
1252 | current library version, and ext2fs_parse_version_string() which | |
1253 | returns a version number based on a e2fsprogs version string. | |
1254 | ||
1255 | The icount functions will return EINVAL if the passed in inode number | |
1256 | is out of bounds. | |
1257 | ||
21c84b71 TT |
1258 | E2fsprogs 1.07 (March 9, 1997) |
1259 | ============================== | |
1260 | ||
1261 | E2fsck is now uses much less memory when checking really large | |
1262 | filesystems (or rather, filesystems with a large number of inodes). | |
1263 | Previously a filesystem with 1 million inodes required 4 megabytes of | |
1264 | memory to store inode count statistics; that storage requirement has | |
1265 | now been reduced to roughly half a megabyte. | |
1266 | ||
1267 | E2fsck can now properly deal with bad blocks appearing inside the | |
1268 | inode table. Instead of trying to relocate the inode table (which | |
1269 | often failed because there wasn't enough space), the inodes in the bad | |
1270 | block are marked as in use. | |
1271 | ||
1272 | E2fsck will automatically try to use the backup superblocks if the | |
1273 | primary superblocks have a bad magic number or have missing meta-data | |
1274 | blocks (or meta-data blocks which are out of range). | |
1275 | ||
1276 | E2fsck's pass 3 has been made more efficient; most noticeable on | |
1277 | filesystems with a very large number of directories. | |
1278 | ||
1279 | Completely revamped e2fsck's system of printing problem reports. It | |
1280 | is now table driven, to make them more easily customizeable and | |
1281 | extendable. Error messages which can be printed out during preen mode | |
1282 | are now one line long. | |
1283 | ||
1284 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | |
1285 | fast symbolic links or deleted files. | |
1286 | ||
1287 | Fixed e2fsck core dumping when fixing a filesystem which has no | |
1288 | directories (not even a root directory). | |
1289 | ||
1290 | Added a check to e2fsck to make sure that the length of every | |
1291 | directory entry is a multiple of 4 (since the kernel complains if it | |
1292 | isn't). | |
1293 | ||
1294 | Added a check to e2fsck to make sure that a directory entry isn't a | |
1295 | link to the root directory, since that isn't allowed. | |
1296 | ||
1297 | Added a check to e2fsk to now make sure the '.' and '..' directory | |
1298 | entries are null terminated, since the 2.0 kernel requires it. | |
1299 | ||
1300 | Added check to write_bitmaps() to make sure the superblock doesn't get | |
1301 | trashed if the inode or block bitmap is marked as being block zero. | |
1302 | ||
1303 | Added checking of the new feature set fields in the superblock, to | |
1304 | avoid dealing with new filesystem features that this package wasn't | |
1305 | set up to handle. | |
1306 | ||
1307 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | |
1308 | try to allocate a block beyond the end of a filesystem. | |
1309 | ||
1310 | When the UUID library picks a random IEEE 802 address (because it | |
1311 | can't find one from a network card), it sets the multicast bit, to | |
1312 | avoid conflicting with a legitimate IEEE 802 address. | |
1313 | ||
1314 | Mke2fs now sets the root directory's owner to be the real uid of the | |
1315 | user running mke2fs. If the real uid is non-zero, it also sets | |
1316 | the group ownership of the root directory to be the real group-id of | |
1317 | the user running mke2fs. | |
1318 | ||
1319 | Mke2fs now has more intelligent error checking when it is given a | |
1320 | non-existent device. | |
1321 | ||
1322 | When badblocks is given the -vv option, it now updates the block that | |
1323 | it is currently testing on every block. | |
1324 | ||
1325 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | |
1326 | currently correctly if PATH wasn't already set. | |
1327 | ||
1328 | Shared libraries now built with dependencies. This allows the shared | |
1329 | library files to be used with dlopen(); it also makes the transition | |
1330 | to libc 6 easier, since ld.so can tell which libc a particular shared | |
1331 | library expects to use. | |
1332 | ||
1333 | Programmer's notes: | |
1334 | ------------------- | |
1335 | ||
1336 | Added new abstraction (defined in dblist.c) for maintaining a list of | |
1337 | blocks which belongs to directories. This is used in e2fsck and other | |
1338 | programs which need to iterate over all directories. | |
1339 | ||
1340 | Added new functions which test to see if a contiguous range of blocks | |
1341 | (or inodes) are available. (ext2fs_*_bitmap_range). | |
1342 | ||
1343 | Added new function (ext2_inode_has_valid_blocks) which returns true if | |
1344 | an inode has valid blocks. (moved from e2fsck code). | |
1345 | ||
1346 | Added new function (ext2fs_allocate_tables) which allocates the | |
1347 | meta-data blocks as part of initializing a filesystem. (moved from | |
1348 | mke2fs code). | |
1349 | ||
1350 | Added a new I/O manager for testing purposes. It will either allow a | |
1351 | program to intercept I/O requests, or print debugging messages to | |
1352 | trace the activity of a program using the I/O manager. | |
1353 | ||
1354 | The badblocks_list functions now store the bad blocks in a sorted | |
1355 | order, and use a binary search to speed up badblocks_list_test. | |
1356 | ||
1357 | The inode scan function ext2fs_get_next_inode() may now return a soft | |
1358 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | |
1359 | those cases where part of an inode table is missing or there is a bad | |
1360 | block in the inode table. | |
1361 | ||
1362 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | |
1363 | the callback function to return a pointer (block and offset) to the | |
1364 | reference of the block. | |
1365 | ||
1366 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | |
1367 | application to jump to a particular block group while doing an inode | |
1368 | scan. | |
1369 | ||
1370 | The badblocks list functions were renamed from badblocks_* to | |
1371 | ext2fs_badblocks_*. Backwards compatibility functions are available | |
1372 | for now, but programs should be modified to use the new interface. | |
1373 | ||
1374 | Some of the library functions were reorganized into separate files to | |
1375 | reduce the size of some programs which statically link against the | |
1376 | ext2 library. | |
1377 | ||
1378 | Put in some miscellaneous fixes for the Alpha platform. | |

1381 | E2fsprogs 1.06 (October 7, 1996) | |
1382 | ================================ | |
1383 | ||
1384 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | |
1385 | smash the backup copies in ext2fs_close(). (The problem was that when | |
1386 | e2fsck -p discovered the problem, while it was closing the filesystem | |
1387 | and exiting, it was also blowing away the backup superblocks on the | |
1388 | disk, which was less than friendly.) We now make it the case that we | |
1389 | only write out the backup superblock and the back block descriptors if | |
1390 | the filesystem is completely free from problems. | |
1391 | ||
1392 | Fixed a bug in block_interate in the lib/ext2fs library which caused | |
1393 | e2fsck to fail on GNU Hurd-created filesystems. | |
1394 | ||
1395 | Add support for Linux/FT's bootloader, which actually uses | |
1396 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | |
1397 | to clear the inode. | |
1398 | ||
1399 | Add support for the "A" (no atime update) attribute. (Note: this | |
1400 | attribute is not yet in production kernels.) | |
1401 | ||
1402 | The test suite is not automatically run when doing a "make all" from | |
1403 | the top level directory. Users should manually run "make check" if | |
1404 | they wish to run the test suite. | |
1405 | ||
1406 | Upon a preenhalt(), make the printed message more explicit that | |
1407 | running e2fsck "MANAULLY" means without the -p or -a options. | |
1408 | ||
1409 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | |
1410 | instead of offering to connect it to lost+found. | |
1411 | ||
1412 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | |
1413 | e2fsck to be run over it, change e2fsck to explicitly display this | |
1414 | fact. | |
1415 | ||
1416 | For dumpe2fs and e2fsck, cause the -V option to print out which | |
1417 | version of the ext2fs library is actually getting used. (This will | |
1418 | help detect mismatches of using a 1.06 utility with a 1.05 library, | |
1419 | etc.) | |
1420 | ||
1421 | Programmers' notes: | |
1422 | ------------------- | |
1423 | ||
1424 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | |
1425 | the naming convention. | |
1426 | ||
1427 | In ext2fs_initialize(), make sure the description for the inode bitmap | |
1428 | is correctly initialize. | |
1429 | ||
1430 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | |
1431 | ||
fc6d9d51 TT |
1432 | E2fsprogs 1.05 (September 7, 1996) |
1433 | ================================== | |
1434 | ||
1435 | Add support for new fields in the ext2 superblock --- volume name, | |
1436 | volume UUID, and last mounted field. Dumpe2fs displays these fields, | |
1437 | tune2fs and mke2fs allows you to set them. E2fsck will automatically | |
1438 | generate a UUID for those volumes that don't have them. | |
1439 | ||
1440 | Put in support for e2fsck to recognize HURD specific ext2 features --- | |
1441 | most notably, the translator block. The e2fsprogs tools will now use | |
1442 | the creator_os field in the superblock to correctly handle different | |
1443 | OS-specific variants of the ext2 filesystem. | |
1444 | ||
1445 | E2fsck now fixes inodes which have a the deletion time set, but which | |
1446 | have a non-zero i_link_count field by offering to clear the deletion | |
1447 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c | |
1448 | ext2 kernel behavior) and offered to unlink the file. | |
1449 | ||
1450 | If e2fsck sets the clean bit, but nothing else, set the exit code | |
1451 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it | |
1452 | set the filesystem valid bit when it was previously cleared. :-) This | |
1453 | was needed to make the HURD fsck driver happy. | |
1454 | ||
1455 | If the user refuses to attach an unattached inode, e2fsck will no | |
1456 | longer set the inode's link count. Otherwise, the inode would end up | |
1457 | getting marked as unused, which might cause loss of data later. | |
1458 | ||
1459 | Make the message issued by e2fsck when the superblock is corrupt less | |
1460 | confusing for users. It now mentions that another reason for the | |
1461 | "corrupt superblock" message might be that the partition might not be | |
1462 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | |
1463 | ||
1464 | Make the libext2 library more robuest so that e2fsck won't coredump on | |
1465 | an illegal superblock where the blocksize is zero. (f_crashdisk is | |
1466 | the test case). | |
1467 | ||
1468 | By default, create filesystems where the default checkinterval is 6 | |
1469 | months (180 days). Linux servers can be robust enough that 20 reboots | |
1470 | can be a long, long time. | |
1471 | ||
1472 | Added configure flag --enable-old-bitops, which forces the bitops to | |
1473 | use the old (native) bitmask operations. By default on the sparc | |
1474 | platform, the standard ext2 bit ordering is now used. | |
1475 | ||
1476 | Added a new feature to e2fsck to byte-swap filesystems; this can be | |
1477 | used to convert old m68k filesystems to use the standard byte-order | |
1478 | storage for the superblock, inodes, and directory blocks. This | |
1479 | function is invoked by using the '-s' option to e2fsck. | |
1480 | ||
1481 | Debugfs's "dump" command has been enhanced so that it writes out the | |
1482 | exact size of the file so that the nulls at the end of the file are | |
1483 | eliminated. The command also accept a new "-p" option which will | |
1484 | attempt preserve to preserve the ownernship, permissions, and | |
1485 | file modification/access times. | |
1486 | ||
1487 | Debugfs has two new options, -f and -R. The -R option allows the user | |
1488 | to execute a single debugfs command from the command line. The -f | |
1489 | option allows the user to specify a "command file" containing debugfs | |
1490 | commands which will get executed. | |
1491 | ||
1492 | Dumpe2fs now pretty prints the check interval, instead of just | |
1493 | printing the check interval as a number of seconds. | |
1494 | ||
1495 | Fix bugs in debugfs: the params command when no filesystem is opened | |
1496 | no longer causes a core dump. It is now possible to unlink a file | |
1497 | when a pathame containing a '/' is specified. | |
1498 | ||
1499 | Tune2fs has a new -C option which sets the number of times the | |
1500 | filesystem has been mounted. | |
1501 | ||
1502 | Fix the chattr '-v' option so that it actually works. Chattr was | |
1503 | being buggy about the -v option parsing. | |
1504 | ||
1505 | Programmers' notes: | |
1506 | ------------------- | |
1507 | ||
1508 | The directory lib/uuid contains a set of library routines to generate | |
1509 | DCE compatible UUIDs. | |
1510 | ||
1511 | Extended ext2fs_namei() to handle symbolic links. Added new function | |
1512 | ext2fs_nami_follow() which will follow last symbolic link in the case | |
1513 | where the pathname points to a sym link. | |
1514 | ||
1515 | The ext2fs_block_iterate function will now return the HURD translator | |
1516 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the | |
1517 | iterator to return data blocks only. The ext2fs.h file now defines | |
1518 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | |
1519 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | |
1520 | count field of the iterator callback function. | |
1521 | ||
1522 | The test script driver now takes an optional second argument, which is | |
1523 | the test case to be run. This allows you to run a test case without | |
1524 | needing to run the entire test suite. | |
1525 | ||
1526 | On Linux ELF systems, install the .so files in the correct places | |
1527 | (/usr/lib). The .so files must be stored in the same directory as the | |
1528 | .a files. | |
1529 | ||
1530 | Fixed miscellaneous HURD compilation issues with header file being | |
1531 | included in the right order. | |
1532 | ||
1533 | Fixed debugfs so that it resets optind to zero, not one, since setting | |
1534 | optind to zero is more correct. | |
1535 | ||

1537 | E2fsprogs 1.04 (May 16, 1996) |
1538 | ============================= | |
1539 | ||
1540 | First "official" (1.03 was a limited release only) to support building | |
1541 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | |
1542 | kernels). | |
1543 | ||
1544 | This package includes a RPM specs file, that it can be built using the | |
1545 | RedHat Package Manager. | |
1546 | ||
1547 | E2fsck now prints a hint that if there are lots of incorrectly located | |
1548 | inode bitmaps, block bitmaps, and inode table blocks, the user might | |
1549 | want to try using e2fsck -b 8193 first, to see if that fares any | |
1550 | better. | |
1551 | ||
1552 | For ext2 filesystem written with the hurd, debugfs will now print out | |
1553 | the translator field when printing an inode structure. | |
1554 | ||
1555 | Lots of miscellaneous linking/installation cleanups: | |
1556 | ||
1557 | Libraries are now linked using a relative pathname, instead of | |
1558 | relying on -L working correct. It doesn't, in many cases, including | |
1559 | current versions of GNU ld. This guarantees that the build tree is | |
1560 | linking with the right libraries, instead of the ones installed in | |
1561 | /usr/lib. | |
1562 | ||
1563 | Header files, man pages, and the et/ss shell scripts are now | |
1564 | generated using a custom substitution script, instead of relying on | |
1565 | the configure script. This prevents needless recompilation of | |
1566 | files; in addition, the custom substitution script is much faster. | |
1567 | ||
1568 | e2fsck may now be linked dynamically, by using the | |
1569 | --enable-dynamic-e2fsck flag to configure. This is not recommended, | |
1570 | since it increases e2fsck's dependence on other files, but some | |
1571 | people need to save disk space, and other critical programs on their | |
1572 | systems were being linked dynamically anyway. | |
1573 | ||
1574 | Programs such as fsck which didn't need to be linked against | |
1575 | libext2fs (or mke2fs which didn't need to be linked against libe2p) | |
1576 | only link against libraries they actually need. Otherwise, those | |
1577 | programs would require the presense of libraries that otherwise | |
1578 | could be removed from a rescuse diskette. | |
1579 | ||
1580 | The ss include files are now installed correctly so they can | |
1581 | actually be used by another package. | |
1582 | ||
1583 | If the profiling libraries are built, they are now installed on a | |
1584 | "make install-libs". | |
1585 | ||
1586 | ||
7f88b043 TT |
1587 | E2fsprogs 1.03 (March 27, 1996) |
1588 | =============================== | |
1589 | ||
1590 | Change the m68k bit numbering for bitmasks to match the bit numbering | |
1591 | used by all other ext2 implementations. (This change was requested by | |
1592 | the m68k kernel development team.) | |
1593 | ||
1594 | Support (in-development) filesystem format revision which supports | |
1595 | (among other things) dynamically sized inodes. | |
1596 | ||
1597 | Fixed a bug in the ext2 library so that an intelligent error is | |
1598 | returned if mke2fs is run with a ridiculously small number of blocks | |
1599 | for a partition. | |
1600 | ||
1601 | Fixed a bug in the ext2 library which required that the device be | |
1602 | openable in read/write mode in order to determine its size. This | |
1603 | caused e2fsck -n to require read/write access when it was not | |
1604 | previously necessary. | |
1605 | ||
1606 | Fixed a bug in e2fsck which casued it to occasionally fail the test | |
1607 | suite depending on which version of the floating point library it was | |
1608 | using. | |
1609 | ||
1610 | Fixed a bug in e2fsck so that it now halts with a fatal error when | |
1611 | certain superblock consistency checks fail. Previously it continued | |
1612 | running e2fsck, with some potential confusing/damaging consequences. | |
1613 | ||
1614 | Added new flag to fsck which allows the root to be checked in parallel | |
1615 | with other filesytems. This is not the safest thing in the world to | |
1616 | do, but some system administrators really wanted it. | |
1617 | ||
fc6d9d51 TT |
1618 | Fixed -Wall flames in lib/ss. |
1619 | ||
74becf3c TT |
1620 | |
1621 | E2fsprogs 1.02 (January 16, 1996) | |
1622 | ================================= | |
1623 | ||
1624 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | |
1625 | ||
1626 | Change e2fsck to print statistics of how many non-contiguous files are | |
1627 | on the system. Note that a file which is larger than 8k blocks, it is | |
1628 | guaranteed to be non-contiguous. | |
1629 | ||
1630 | In mke2fs, print a warning message if a user tries to format a whole | |
1631 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a | |
1632 | whole disk, the -F (force) option forces mke2fs to format a whole disk | |
1633 | as a filesytem. | |
1634 | ||
1635 | Fix a bug in fsck where in some cases it might start checking | |
1636 | partitions in the next pass before it finishes checking partitions in | |
1637 | the current pass. This still won't cause two partitions on the same | |
1638 | disk will be checked, so it's rarely a problem in real life. | |
1639 | ||
1640 | Patch lsattr so that it won't hang when checking a named pipe. | |
1641 | ||
1642 | Minor compilation fixes: | |
1643 | * Fix the order of libraries that were linked in debugfs. | |
1644 | * Allow the sources to be compiled with -ansi turned on. |
