bae55640 | 1 | E2fsprogs 1.39-WIP (May 14, 2006) |
34a2611c TT |
2 | =================================== |
3 | ||
34a2611c TT |
4 | Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems |
5 | between 2**31 and 2**32 blocks. | |
6 | ||
34a2611c TT |
7 | Change mke2fs to use /etc/mke2fs.conf as a configuration file to |
8 | configure the filesystem features, blocksize, and inode_ratio for | |
9 | different filesystem types. | |
10 | ||
11 | The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the | |
12 | filesystem device node in exclusive mode to prevent accidents by | |
13 | system administrators. In the case of resize2fs and mke2fs, it will | |
14 | only use exclusive mode if the filesystem is not mounted. | |
15 | ||
16 | Fixed a bug in mke2fs which caused it to to fail when creating the | |
17 | resize inode for large filesystems. (Addresses Debian Bug #346580) | |
18 | ||
bae55640 TT |
19 | When allocating space for the RAID filesystems with the stride |
20 | parameter, mke2fs will now place each portion of the group's inode | |
21 | table right up after the superblock (if present) in order to minimize | |
22 | fragmentation of the freespace. | |
23 | ||
24 | Speed up mke2fs and e2fsck by writing inode and block bitmaps more | |
25 | efficiently by writing the inode and block bitmaps in one pass, thus | |
26 | reducing the number of disk seeks required. | |
27 | ||
34a2611c TT |
28 | Add support for on-line resizing to resize2fs. |
29 | ||
30 | Fix blkid library so that logic to determine whether or not a device's | |
31 | cached information in /etc/blkid.tab needs to be verified or not | |
32 | doesn't get confused by a system clock which is insane (for example, | |
33 | if the battery is dead on a Macintosh running PPC Linux. (Addresses | |
34 | Red Hat Bug: #182188) | |
35 | ||
36 | The blkid library will now store the UUID of the external journal used | |
37 | by ext3 filesystems, so that in the future, the userspace mount binary | |
38 | can use this to find the location of the external journal and pass | |
39 | this information to the kernel. | |
f3227850 TT |
40 | |
41 | E2fsck will now consult a configuration file, /etc/e2fsck.conf to | |
34a2611c TT |
42 | control how various options should be handled. See the e2fsck.conf |
43 | man page for more details. (Addresses Debian Bug: #150295) | |
f3227850 | 44 | |
34a2611c TT |
45 | E2fsck now prints an explanatory message when delaying a filesystem |
46 | check when the system is running on battery. (Addresses Debian Bug: | |
47 | #350306) | |
f2b74cda | 48 | |
4c02c41c TT |
49 | E2fsck will detect if the superblock's last mount field or last write |
50 | field is in the future, and offer to fix if so. (Addresses Debian Bug | |
f3227850 TT |
51 | #327580) These problems will be fixed automatically in preen mode |
52 | since Debian's boot sequence bogusly doesn't set the time correctly | |
53 | until potentially very late in the bootup process, and this can cause | |
54 | false positives which will cause users' systems to fail to boot. | |
55 | (Addresses Debian Bugs #343662 and #343645) | |
f2b74cda | 56 | |
34a2611c TT |
57 | E2fsck now checks to see if the superblock hint for the location of |
58 | the external journal is incorrect, and if so, offer to update it. | |
59 | (Addresses Debian Bug: #355644) | |
60 | ||
f2b74cda TT |
61 | Fix e2fsck from segfaulting on disconnected inodes that contain one or |
62 | more extended attributes. (Addresses Debian Bug: #316736, #318463) | |
63 | ||
4c02c41c TT |
64 | E2fsck will stop and print a warning if the user tries running a |
65 | read/write badblocks test on a read-only mounted root filesystem. | |
66 | ||
bae55640 TT |
67 | Fix a memory leak in e2fsck's error paths. (Thanks to Michael |
68 | C. Thompson for pointing these out; they were originally found using | |
69 | Coverity.) | |
70 | ||
f3227850 TT |
71 | When resizing a file containing a filesystem, resize2fs will expand or |
72 | truncate a file as necessary. (Addresses Debian Bug: #271607) | |
73 | ||
bae55640 TT |
74 | Resize2fs will now automatically determine the RAID stride parameter that |
75 | had been used to create the filesystem, and use that for newly created | |
76 | block groups. The RAID stride parameter may also be manually specified | |
77 | on the command line using the new -S option to resize2fs. | |
78 | ||
4c02c41c TT |
79 | Fix mke2fs so that it correctly creates external journals on |
80 | big-endian machines (such as a S/390). | |
81 | ||
bae55640 TT |
82 | Fix a bug in the e2p library which could cause dumpe2fs to (rarely) |
83 | fail to print out the journal or hash seed UUID. (Thanks to Guillaume | |
84 | Chambraud for pointing this out.) | |
85 | ||
86 | Dumpe2fs will now print the size of the journal (if present). | |
87 | ||
4c02c41c TT |
88 | Fix debugfs's set_inode_field command so it can properly set the frag, |
89 | fsize, uid_high, gid_high, and author fields in the inode instead of | |
90 | silently failing, and so that setting the i_size actually sets i_size | |
91 | correctly. | |
92 | ||
93 | Add a new debugfs command, set_current_time, which sets fs->now so | |
94 | that regression test suites can repeatedly modify the filesystem's | |
95 | last_write fields. | |
96 | ||
34a2611c TT |
97 | Fix a bug in debugfs's icheck which would incorrectly report the owner |
98 | of an extended attribute block. | |
99 | ||
bae55640 TT |
100 | Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a |
101 | print a usage message when an illegal option character is given. | |
102 | ||
103 | Fix mklost+found so that it creates a full-sized directory on | |
104 | filesystems with larger block sizes. | |
105 | ||
106 | Fix a file descriptor leak in blkid library. | |
107 | ||
4c02c41c TT |
108 | Fix a display bug in "badblocks -sv" so that the done message properly |
109 | clears the block number at the end of the test. (Addresses Debian Bug | |
110 | #322231) | |
111 | ||
f2b74cda TT |
112 | Allow fractional percentages to the -m option in mke2fs and tune2fs |
113 | (Addresses Debian Bug: #80205) | |
114 | ||
115 | Use fstat/fstat64 in getsize.c if the the target is a regular file, | |
116 | instead of attempting to do a binary search. Fix some fd leaks in | |
117 | error cases. | |
118 | ||
34a2611c TT |
119 | Add support for device mapper library to the blkid library to ensure |
120 | that the "best" (i.e., leaf) device is probed by the blkid library. | |
121 | ||
4c02c41c TT |
122 | Fix the blkid library so that it notices when an ext2 filesystem is |
123 | upgraded to ext3. | |
124 | ||
125 | Improve the blkid's library VFAT/FAT detection; it now understands | |
126 | labels stored in the root directory, and is more paranoid about | |
127 | checking the FAT superblock values. | |
128 | ||
34a2611c TT |
129 | Fixed a fd leak in the uuid library which was causing problems for the |
130 | LVM tools. (Addresses Debian Bug: #345832) | |
131 | ||
4c02c41c TT |
132 | Add support for the reiser4 and software suspend partitions to the |
133 | blkid library. Also add support for extract the label from iso9660 | |
134 | filesystems. | |
135 | ||
f2b74cda TT |
136 | Fix a compile_et bug which miscount the number of error messages if |
137 | continuations are used in the .et file. | |
138 | ||
139 | Add extra sanity checks to protect users from unusual cirucmstances | |
140 | where /etc/mtab may not be sane, by checking to see if the device is | |
141 | reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug | |
142 | #319002) | |
143 | ||
34a2611c TT |
144 | Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian |
145 | Bug: #343149, #341911, #300871, #316604, #316782, #330789) | |
4c02c41c | 146 | |
f2b74cda TT |
147 | Fix use-after-free bug in e2fsck when finishing up the use of the |
148 | e2fsck context structure. | |
149 | ||
34a2611c TT |
150 | Fixed spelling mistakes, typos, and otherwise clarified man pages and |
151 | documentation. (Addresses Debian Bugs: #329859, #322188, #316811, | |
152 | #312515, #351268, #357951, #347295, #316040) | |
4c02c41c | 153 | |
f2b74cda | 154 | Fixed various Debian packaging issues --- see debian/changelog for |
3285a9c9 | 155 | details. (Addresses Debian Bugs #317862, #320389, #290429, #310950, |
bae55640 TT |
156 | #310428, #330737, #330736, #329074, #356293, #360046, #366017, #364516) |

158 | |
159 | Programmer's notes: | |
160 | ------------------- | |
161 | ||
7e2ec011 TT |
162 | Update config.guess and config.sub to latest version (2006-02-23) from |
163 | FSF. | |
164 | ||
165 | Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian | |
166 | Bugs: #360661, #360317) | |
167 | ||
34a2611c TT |
168 | Fixed the Makefile so that they work correctly on newer versions of |
169 | GNU make (i.e., 3.81). | |
170 | ||
f2b74cda TT |
171 | Add valgrind support to the regression test suites, and eliminate |
172 | false positives from valgrind. | |
173 | ||
4c02c41c TT |
174 | Add a regression test suite for the blkid library. |
175 | ||
f2b74cda TT |
176 | Fix a fencepost error in resize2fs caught by valgrind. |
177 | ||
4c02c41c TT |
178 | Fix compiler warnings about missing memcpy prototypes. |
179 | ||
180 | We no longer have the sparc assembly code in the header file any more, | |
181 | so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would | |
182 | break compiles on the sparc architectures when using gcc. | |
183 | ||
184 | In the libext2fs library, add the new field fs->now which if non-zero | |
185 | is used instead of the system time when setting various filesystem | |
186 | fields (last modified time, last write time, etc.) | |
187 | ||
188 | Fix gcc 4.01 complaints by adding a missing #include <string.h> to | |
189 | ext2fs.h which is needed since the inline functions use memcpy(). | |
190 | (Addresses Sourceforge Bug #1251062) | |
191 | ||
192 | Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in | |
193 | the build system when building files in the util directory which are | |
194 | needed during the build process. This avoids potential problems when | |
195 | cross-compiling and some of the options specified in CFLAGS or LDFLAGS | |
196 | are not recognized as valid by the host compiler. (Addresses | |
197 | Sourceforge Bug #1261547) | |
198 | ||
199 | Clean up the blkid library by making the superblock and generic i/o | |
200 | functions to be more generic. Clean up interface to the probe | |
201 | function, and fix memory leak. Finallly, remove an unneeded reference | |
202 | to probe.h in the lib/blkid/resolve.c | |
203 | ||
3285a9c9 TT |
204 | Add an ext2fs_read_bb_FILE regression test to confirm proper detection |
205 | of invalid block #'s. | |
206 | ||
34a2611c TT |
207 | The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to |
208 | indicate that the the function read/writes the memory location. | |
209 | ||
3285a9c9 TT |
210 | Fix various gcc -Wall complaints. |
211 | ||
212 | Add a dependency to make sure that the subdirectories are created | |
213 | before creating all of the object files, in order to address parallel | |
214 | build problem in the library Makefiles. (Addresses Sourceforge Bug: | |
215 | #1261553) | |
216 | ||
217 | Add $(LDFLAGS) to the command line argument when generating an ELF or | |
218 | Solaris shared library, to allow cross-compile and other builds that | |
219 | might need to specify -L paths to needed libraries. (Addresses | |
220 | Sourceforge Bug #1261549) | |
221 | ||
bae55640 TT |
222 | Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially |
223 | intended for testing purposes. It allows an ext2/ext3 developer to | |
224 | create very large filesystems using sparse files where most of the | |
225 | block groups are not initialized and so do not require much disk | |
226 | space. Eventually it could be used as a way of speeding up mke2fs and | |
227 | e2fsck for large filesystem, but that would be best done by adding an | |
228 | RO_COMPAT extension to the filesystem to allow the inode table to be | |
229 | lazily initialized on a per-block basis, instead of being entirely | |
230 | initialized or entirely unused on a per-blockgroup basis. | |
231 | ||

fea95ffc | 233 | E2fsprogs 1.38 (June 30, 2005) |
1f965c8d TT |
234 | ============================== |
235 | ||
236 | Fix blkid's test programs (built with "make check") compile correctly | |
237 | even without "configure --enable-blkid-debug". | |
238 | ||
239 | Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict | |
240 | type aliasing rules on newer gcc compilers. (Addresses Red Hat | |
241 | Bugzilla ##161183.) | |
242 | ||
243 | Fix com_err library to make it more compatible with recent changes | |
244 | made to the com_err library in MIT Kerberos V5 version 1.4. | |
245 | (Addresses Sourcefroge Bug #1150146) | |
246 | ||
247 | General cleanup of messages printed by e2fsprogs programs for grammar, | |
248 | consistency, and to make life easier for translators. Fixed a few | |
249 | strings containing English that had not been marked as needing | |
250 | translations. Removed strings that do not need to be translated, to | |
251 | make life easier for translators. | |
252 | ||
253 | Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to | |
254 | test to see if a device appears to be in use instead of just relying | |
255 | on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594). | |
256 | ||
257 | Fix portability problem in the filefrag program affecting platforms | |
258 | where the size of an integer is smaller than the size of a long. | |
259 | (Addresses Debian Bug #309655) | |
260 | ||
261 | Mke2fs will now use a larger journal by default for filesystems | |
262 | greater than 4GB. (128 MB instead of 32MB). | |
263 | ||
264 | Mke2fs will refuse to create filesystems greater than 2**31-1 blocks, | |
265 | unless forced. This is to avoid signed vs. unsigned kernel bugs in | |
266 | block numbers that still need to be fixed. | |
267 | ||
268 | The blkid program has a new option which will more efficiently search | |
269 | for device when it is known (or expected) that only one matching | |
270 | device will be found in the system, such as when doing a lookup by | |
271 | UUID. | |
272 | ||
273 | Debian's e2fsprogs-specific initrd fragment will avoid including | |
274 | unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD | |
275 | and LD_LIBRARY_PATH, and filtering out libraries found in | |
276 | /etc/ld.so.preload. (Addresses Debian Bug: #304003) | |
277 | ||
278 | Fixed a potential portability issue in the blkid programs for | |
279 | architectures where the char type is unsigned. (Addresses Sourceforge | |
280 | Bug: #1180585) | |
281 | ||
282 | Fix a bug in filefrag so that it doesn't falsely count an extra | |
283 | discontinuity when the first block found is an indirect block. | |
284 | (Addresses Debian Bug #307607). | |
285 | ||
286 | Fix blkid's recognition of cramfs filesystems, and enhance it to be | |
287 | able to handle cramfs labels. | |
288 | ||
289 | Fix debugfs's stat command to not core dump when a filesystem is not | |
290 | open. | |
291 | ||
292 | Fix e2fsck's handling of error conditions caused by the resize inode | |
293 | claiming blocks that are also used by other inodes, a filesystem | |
294 | corruption which was commonly caused by a bug in Fedora Core 3's | |
295 | resize2fs program. | |
296 | ||
297 | Fixed bug in filefrag which caused it to fail on non-ext2/3 | |
298 | filesystems. (Addresses Debian Bug: #303509) | |
299 | ||
300 | If the superblock last mount time indicates that the system clock may | |
301 | not be accurate, then e2fsck will omit checking inodes' deletion time | |
302 | field for indications of a potential corrupted orphaned inode list. | |
303 | (Previously e2fsck only ommited these LOW_DTIME checks when the | |
304 | superblock's last write time looked insane.) | |
305 | ||
306 | Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs. | |
307 | (Addresses Debian bug #302200) | |
308 | ||
309 | Make the blkid library more paranoid about being run from setgid | |
310 | programs, and to use __secure_getenv() from libc if it is available. | |
311 | ||
312 | Fixed spelling mistakes, typos, and otherwise clarified man pages. | |
313 | (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593 | |
314 | and Sourceforge Bug: #1189803) | |
315 | ||
316 | Updated and fixed translations. | |
317 | ||
318 | Fixed various Debian packaging issues --- see debian/changelog for | |
319 | details. | |
320 | ||
321 | Programmer's notes: | |
322 | ------------------- | |
323 | ||
324 | Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been | |
325 | changed to take an unsigned int for the bit number. Negative bit | |
326 | numbers were never allowed (and didn't make any sense), so this should | |
327 | be a safe change. This is needed to allow safe use of block numbers | |
328 | greater than or equal to 2**31. | |
329 | ||
330 | The compile_et program will avoid recreating generated foo_err.c and | |
331 | foo_err.h files if no changes are necessary. The compile_et program | |
332 | will also atomically replace these files to avoid a potential parallel | |
333 | build race problem on SMP systems. (Addresses Sourceforge Bug: | |
334 | #1157933) | |
335 | ||
336 | Added a new function to the blkid library, blkid_probe_all_new(), | |
337 | which only probes newly added disk devices, and change | |
338 | blkid_find_dev_with_tag() to use this function so that when a | |
339 | requested tag is not found, devices that were previously not checked | |
340 | are searched before searching all devices in the system. | |
341 | ||
342 | Added new functions to the blkid library, blkid_dev_set_search() and | |
343 | blkid_dev_has_tag(). | |
344 | ||
345 | E2fsck's problem strings can now use @m and @n as abbrevations for | |
346 | "multiply-claimed" and "invalid", respectively. | |
347 | ||
348 | The e2fsprog.pot file now has an explanation of how the @-expansion | |
349 | and %-expansion works, and strings in e2fsck/problem.c which contain @ | |
350 | characters now have comments in e2fsprogs.pot with the @-expansion to | |
351 | make life easier for translators. | |
352 | ||
353 | Fixed missing return values in the ext2fs library which could cause it | |
354 | to return random garbage in certain error conditions. | |
355 | ||
356 | Allow the current time to be overriden via the E2FSCK_TIME environment | |
357 | variable for use in regression tests. | |
358 | ||
359 | The test scrpit driver program now exits with a non-zero status if | |
360 | there any of its test that it ran failed. | |
361 | ||
362 | Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge | |
363 | Bug: #1157933) | |
364 | ||
365 | Fixed "make check" so that it compiles correctly even when e2fsprogs' | |
366 | header files have not be installed in the system include directories. | |
367 | (Addresses Sourceforge Bug: #1180572) | |
368 | ||
369 | Fixed gcc -Wall nits. | |
370 | ||
371 | ||
fd4b28ef TT |
372 | E2fsprogs 1.37 (March 21, 2005) |
373 | =============================== | |
374 | ||
375 | Add support for checking the validity of Extended Attributes stored in | |
376 | inodes to e2fsck. | |
377 | ||
378 | Add support for dumping the contents of large inodes to debugfs, | |
379 | including the extended attributes stored in inodes. | |
380 | ||
381 | Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that | |
382 | when we create a new inode we make sure that the extra information in | |
383 | the inode (any extra fields in a large inode and any ea-in-inode | |
384 | information) is initialized correctly. This can take place when | |
385 | mke2fs creates the root and lost+found directory, when e2fsck creates | |
386 | a new root inode or a new lost+found directory, and when the user uses | |
387 | the debugfs write, mknod, or mkdir commands. Otherwise, the newly | |
388 | create inode could inherit garbage (or old EA information) from a | |
389 | previously deleted inode. | |
390 | ||
391 | Fixed a bug in e2fsck so it would notice if a file with an extended | |
392 | attribute block was exactly 2**32 blocks, such that i_blocks wrapped | |
393 | to zero. | |
394 | ||
395 | Added support to filefrag to detect files which are using the new | |
396 | experimental file extents format, and use the non-ext2 algorithm in | |
397 | that case. Fixed a bug to avoid reporting a false discontinuity if | |
398 | there is one or more unallocated blocks at the beginning of a file. | |
399 | ||
400 | Duplicated a check for noticing whether or not the number of blocks | |
401 | (given a certain blocksize) is greater than 2**32 when the | |
402 | BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This | |
403 | allows mke2fs to automatically use a larger blocksize when creating a | |
404 | filesystem on a very large device when run on systems that do not | |
405 | support BLKGETSIZE64. | |
406 | ||
407 | Fix the I18N build which was broken in e2fsprogs 1.36 because the | |
408 | build system had been switched to treat the .gmo files as shipped | |
409 | files (for backwards compatibility with systems that have older GNU | |
410 | I18N tools installed), but the gen_tarball.in script was still | |
411 | removing the .gmo files from the official source distribution. | |
412 | ||
413 | Fixed various Debian packaging issues --- see debian/changelog for | |
414 | details. (Addresses Debian Bugs ##296769, #299341) | |
415 | ||
416 | Programmer's notes: | |
417 | ------------------- | |
418 | ||
419 | Added new functions to the e2p library which convert between a string | |
420 | and os_type: e2p_os2string() and e2p_string2os(), and used them to | |
421 | make the generated binaries more compact. | |
422 | ||
423 | Fixed a compile-time error on Darwin systems. | |
424 | ||
425 | Cleaned up the lib/ext2fs Makefile slightly. | |
426 | ||

428 | E2fsprogs 1.36 (February 4, 2005) |
429 | ================================= | |
2b0dc0ac TT |
430 | |
431 | All of the patches that were applied to Fedore Core 3's | |
432 | e2fsprogs-1.35-11.2 have been integrated, although sometimes with a | |
433 | lot of bug fixes first. Users of Fedora Core 3 are strongly | |
434 | encouraged to upgrade to e2fsprogs 1.36 as soon as possible. | |
435 | ||
436 | Add support for filesystem with the online resizing via resize inode | |
437 | feature. Fixed numerous bugs from the Fedora patches. The Fedora | |
438 | patches also didn't bother to do any consistency checking on the | |
439 | resize inode, or add any tests to the regression test suite. The "-R | |
440 | resize=4g" option to mke2fs was a no-op in the Fedora patches, despite | |
441 | being listed in mke2fs's usage message. All of these shortcomings | |
442 | have been corrected. | |
443 | ||
444 | E2fsck can also also fix filesystems trashed by Fedora's resize2fs | |
445 | program. In order to do this, the user must run the commands: | |
446 | ||
d0a3b46c | 447 | debugfs -w /dev/hdXXX -R "features ^resize_inode" |
2b0dc0ac TT |
448 | e2fsck -f /dev/hdXXX |
449 | ||
450 | Optionally, the ext2prepare command can be used to re-enable online | |
451 | resizing after the filesystem has been fixed. | |
452 | ||
453 | The fsck program will now accept an optional filedescriptor argument | |
454 | to the -C option. (The Fedora version of this patch would sometimes | |
455 | cause fsck to ignore a parameter on fsck's command line in some rare | |
456 | cases, sigh.) | |
457 | ||
dc256973 TT |
458 | Make sure e2fsprogs doesn't write garbage into the reserved portion of |
459 | large inodes. | |
460 | ||
461 | Make sure resize2fs releases the blocks belonging to the old inode | |
462 | table blocks when moving the inode table. (Addresses Debian Bug: | |
463 | #290894) | |
464 | ||
465 | Skip the r_resize_inode test if resize2fs is not compiled (due to | |
466 | configure --disable-resizer) | |
467 | ||
468 | E2fsck now checks the summary filesystem accounting information, and | |
469 | if any of the information is obviously wrong, it will force a full | |
470 | filesystem check. (Addresses Debian Bug #291571) | |
471 | ||
472 | Fix e2fsck to not complain when the resize_inode feature is enabled, | |
473 | s_reserved_gdt_blocks is zero, and there is no DIND block allocated in | |
474 | the resize inode. | |
475 | ||
8ceb55f0 TT |
476 | Fix e2fsck to note delete symlinks that contain an extended attribute |
477 | after the ext_attr feature flag has been cleared. (Addresses Red Hat | |
478 | Bugzilla #146284). | |
479 | ||
dc256973 TT |
480 | Add new utility program, copy_sparse.c, which is very useful |
481 | for dealing with large sparse files (such as e2image files). | |
482 | ||
483 | Add support for jnl_blocks[] for debugfs's set_super_value. | |
484 | ||
485 | Fix filefrag so that it works correctly with sparse files. | |
486 | ||
3eee5e9e TT |
487 | Filefrag -v will print first and last blocks. |
488 | ||
dc256973 TT |
489 | Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs |
490 | and dumpe2fs. | |
491 | ||
8ceb55f0 TT |
492 | Add mke2fs support so that it can support filesystems larger than 4TB |
493 | automatically, by retrying with a 4k blocksize if the device size is | |
494 | too big to be expressed using a 1k blocksize. (Addresses Sourceforge | |
495 | bug #1106631) | |
496 | ||
dc256973 TT |
497 | Change blkid to test for NTFS first because Windows sometimes doesn't |
498 | clear enough of the parition to confuse the probing routines into | |
499 | thinking the old filesystem type is still valid. (Addresses Debian | |
500 | Bug #291990) | |
501 | ||
66fa0de8 TT |
502 | Add support for swap partition label and uuid's in the blkid library. |
503 | ||
dc256973 TT |
504 | Add support to the blkid library to recognize Oracle ASM volumes. |
505 | ||
506 | Make blkid -t display all devices that match the specified criteria, | |
8ceb55f0 TT |
507 | not just the first one, and work more consistently when the blkid |
508 | cache file is not available or set to /dev/null. (Addresses Debian | |
509 | Bug #290530 and #292425) | |
dc256973 | 510 | |
2b0dc0ac TT |
511 | Badblocks will now correctly display block numbers greater than |
512 | 999,999,999 in its progress display. | |
513 | ||
514 | The tune2fs program will not allow the user from setting a ridiculous | |
515 | number of reserved blocks which would cause e2fsck to assume the | |
516 | superblock was corrupt. E2fsck's standards for what is a ridiculous | |
517 | number of reserved block has also been relaxed to 50% of the blocks in | |
518 | the filesystem. | |
519 | ||
520 | The blkid library will return vfat in preference to msdos, and ext3 in | |
521 | preference to ext2 (if the journalling flag is set) so that mount will | |
522 | do the right thing. (Addresses Debian bug #287455) | |
523 | ||
524 | Mke2fs will now use the -E option for extended options; the old -R | |
525 | (raid options) option is still accepted for backwards compatibility. | |
526 | Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707) | |
527 | ||
528 | Mke2fs will now accept a size in megabytes, gigabytes, and other units | |
529 | (via "32m" or "4g" on the command line) if the user finds this more | |
530 | convenient than specifying a block count. | |
531 | ||
532 | Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode | |
533 | cache conherency problem. | |
534 | ||
535 | Debugfs now supports a new command, set_inode_field, which allows a | |
536 | user to manually set a specific inode field more conveniently, as well | |
537 | as set entries in the indirect block map. | |
538 | ||
539 | Debugfs's set_super_value command has been enhanced so that the user | |
540 | can set most superblock fields, including the date/time fields and | |
541 | some of the more newsly added superblock fields. | |
542 | ||
543 | E2fsprogs programs now accept an offset to be passed to the file | |
544 | specifiers, via the syntax: "/tmp/test.img?offset=1024". | |
545 | ||
546 | E2fsprogs programs will now accept blocksizes up to 65536; kernel | |
547 | support on the x86 doesn't exist for now, but it can be useful on | |
8ceb55f0 TT |
548 | other architectures with page sizes greater than 4k. There are 2.6 |
549 | kernel patches out there which enable this, but they are of this | |
550 | writing still experimental. | |
2b0dc0ac | 551 | |
4ee558fc TT |
552 | The e2image command now takes the -s option which will scramble |
553 | directory entries for raw image files. | |
554 | ||
555 | Fix a file descriptor leak in the filefrag program. | |
556 | ||
557 | Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not | |
558 | present. | |
559 | ||
2b0dc0ac TT |
560 | Fix bug in debugfs where kill_file would lead to errors when deleting |
561 | devices and symlinks. (Sourceforge Bugs #954741 and #957244) | |
562 | ||
563 | Fix bug in the blkid library when detecting the ocfs1 filesystem | |
564 | ||
565 | Remove obsolete EVMS 1.x and a.out DLL support. | |
566 | ||
567 | E2fsck will attempt to recover from a journal containing illegal blocks. | |
48301129 TT |
568 | |
569 | Fixed two potential ordering constraint problems in e2fsck which might | |
570 | cause the filesystem to be corrupted if e2fsck is interrupted during a | |
571 | (extremely narrow) race window. Thanks to Junfeng Yang from the | |
572 | Stanford Metacompilation group for pointing this out. | |
573 | ||
574 | Fixed bug in e2fsck where it would not accurately detect whether or | |
575 | not the system is running on adaptor if the ACPI device representing | |
576 | the AC adapter didn't correspond to the what was used on IBM | |
577 | Thinkpads. | |
578 | ||
579 | Change e2fsck to accept directories greater than 32MB. | |
580 | ||
581 | Fix e2fsck so that a checkinterval of zero disables a time-based check | |
582 | of the filesystem. | |
583 | ||
584 | Debugfs will check the DEBUGFS_PAGER enviroment variable in preference | |
585 | to the PAGER environment variable. (Addresses Debian Bug #239547) | |
586 | ||
587 | Tune2fs will not mark rewrite the superblock if the feature bitmasks | |
588 | are not modified. | |
589 | ||
590 | The debugfs program will set the filetype information when creating a | |
591 | link. | |
592 | ||
593 | Add debugfs -d option to use a separate source of data blocks when | |
594 | reading from an e2image file. | |
595 | ||
596 | Add e2image -I option which allows the e2image metadata to be | |
597 | installed into a filesystem. | |
598 | ||
599 | Fixed bug in the badblocks program which caused "done" to always | |
600 | appear in english even when a translation was available. (Addresses | |
601 | Debian Bug #252836) | |
602 | ||
603 | The blkid program has a new option -o which controls the output format | |
604 | of the blkid program; this is makes blkid more convenient to use in | |
605 | shell scripts. | |
606 | ||
607 | Fix a minor bug in uuid library, which was not using the full 14 bits | |
608 | of clock sequence when generating UUID's. | |
609 | ||
610 | Fix a Y8.8888K problem in the uuid library. | |
611 | ||
612 | Logsave now creates a new session id for itself to avoid getting | |
613 | killed by init whan transitioning between init levels. | |
614 | ||
615 | Change the licensing of the UUID library to be the 3-clause BSD-style | |
616 | license; this allows Apple to use the uuid library in Darwin. | |
617 | ||
618 | Add ocfs and ocfs2 probe support into the blkid library. | |
619 | ||
620 | Fix a memory and file descriptor leak in the blkid library. | |
621 | ||
622 | The blkid library will revalidate the device if the system time is | |
623 | earlier than last verification time of the device, since that | |
624 | indicates that the system time is probably nottrustworthy. | |
625 | ||
626 | The blkid library will override the default location of the blkid.tab | |
627 | file by the BLKID_FILE environment variable, if it is available. | |
628 | ||
629 | Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6. | |
630 | ||
631 | Add various portability fixes for lame new versions of glibc, Darwin | |
632 | and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian | |
2b0dc0ac TT |
633 | Bugs #239934, #264630, #269044, #255589, #289133) |
634 | ||
635 | Add support for Windows 9x/NT under Cygwin. | |
48301129 TT |
636 | |
637 | Updated and clarified various man pages. (Addresses Debian Bugs #236383, | |
2b0dc0ac | 638 | #241940, #238741, #242995, #256669, #268148, #256760, #273679) |
48301129 TT |
639 | |
640 | Updated and fixed translations. (Addresses Debian bugs #244105, #262836) | |
641 | ||
642 | Update the rpm spec files so that it works better with Fedora core 2 | |
643 | and RH9. | |
644 | ||
645 | Fixed various Debian packaging issues (see debian/changelog). In | |
646 | particular, fixed the Debian initrd scripts. (#241183, #248050, | |
647 | #253595, #247775) | |
648 | ||
649 | ||
650 | Programmer's notes: | |
651 | ------------------- | |
652 | ||
2b0dc0ac | 653 | Fixed various gcc -Wall warnings. |
48301129 TT |
654 | |
655 | The uuid library now has new functions uuid_unparse_upper() and | |
656 | uuid_unparse_lower() which forces the case of the hex digits to be | |
657 | upper case, or lower case. | |
658 | ||
659 | The build process has been speeded up by enhancing the subst program | |
660 | to update the modtime on the generated files even when the generated | |
661 | file hasn't changed. | |
662 | ||
663 | The uuid library now uses C99 stdint.h types instead of custom types. | |
664 | ||
665 | Updated config.guess and config.sub with newer versions from the FSF. | |
666 | ||
667 | Removed out of date .cvsignore files from the source distribution. | |
668 | ||
2b0dc0ac TT |
669 | The ext2fs_unlink() function will return an error if both the name and |
670 | inode number are unspecified, to avoid doing something surprising | |
671 | (such as unconditionally deleting the first directory entry). | |
672 | Directory entries are now deleted by coalescing them with the previous | |
673 | directory entry if possible, to avoid directory fragmentation. This | |
674 | is not an issue with the e2fsprogs suite, but may be a problem for | |
675 | some of the users of libext2fs, such as e2tools. | |
676 | ||
677 | Add support for version numbers of the form "1.36-rc1". | |
678 | ||
48301129 TT |
679 | Fix build of mke2fs.static. |
680 | ||
dc256973 TT |
681 | Add basic ext2fs library support for large (EA in inode) inodes. |
682 | ||
48301129 TT |
683 | The test_io mechanism can now abort after n reads or writes to a |
684 | particular block. The block is specified by TEST_IO_BLOCK environment | |
685 | variable, and the read/write count by the TEST_IO_READ_ABORT and | |
686 | TEST_IO_WRITE_ABORT environment variables. The block data is now only | |
687 | dumped if the 0x10 bit is set in TEST_IO_FLAGS. | |
688 | ||
689 | UUID_DEFINE() in the uuid library now creates a static variable, with | |
690 | __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can | |
691 | be used in header files. | |
692 | ||
2b0dc0ac TT |
693 | Add support for the install-strip and install-shlibs-strip targets, as |
694 | suggested by the GNU coding guielines. "make install" no longer | |
695 | strips the binaries which are installed. | |
696 | ||
3eee5e9e TT |
697 | Remove support for the --enable-old-bitops configure option which was |
698 | only for very old sparc systems. | |
699 | ||
700 | Remove support for --enable-clear-htree; this was only needed during | |
701 | the early development of the htree patch. | |
702 | ||
2b0dc0ac TT |
703 | Use Linux-kernel-style makefile output so it is easier to see compiler |
704 | warnings. | |
705 | ||
706 | Update gettext files to version 0.14.1. | |
707 | ||
708 | Update to use autoconf 2.5x. | |
709 | ||
710 | Improved support for compiling e2fsprogs under dietlibc. | |
711 | ||
4ee558fc TT |
712 | Make e2fsprogs portable to Solaris and FreeBSD systems. |
713 | ||
8ceb55f0 TT |
714 | Add blkid_verify(), blkid_get_library_version(), and |
715 | blkid_parse_version_string() functions to the blkid library. | |
dc256973 TT |
716 | |
717 | Add pkg-config files for e2fsprogs's libraries. | |
718 | ||
719 | Fix "make uninstall" to so that it removes everything that is installed. | |
720 | ||
3eee5e9e TT |
721 | Add a configure --enable-maintainer-mode option which enables the |
722 | makefile rules to rebuild the configure script from configure.in, and | |
723 | to reubuild the .gmo files in po directory. | |
724 | ||
725 | Drop the sparc assembly bitwise operations; it's less efficient | |
726 | than the GCC 3.4 compile code and triggers compiler warnings on | |
727 | sparc64. Thanks to Matthias Andree for his analysis and suggestions. | |
728 | (Addresses Debian Bug #232326) | |

731 | E2fsprogs 1.35 (February 28, 2004) |
732 | ================================== | |
733 | ||
48301129 | 734 | E2fsck has a new -k option, which in conjunction with the -c options, |
b70b1167 TT |
735 | preserves the existing badblocks list. |
736 | ||
48301129 | 737 | Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d. |
b70b1167 TT |
738 | |
739 | E2fsprogs will now deal correctly with symlinks that contain | |
740 | extended attribute information, which can be created using SE Linux. | |
741 | (Addresses Debian Bug #232328) | |
742 | ||
743 | Remove a double longjump into an invalid stack frame bug in e2fsck. | |
744 | (This was during an abort sequence, which normally worked on Linux and | |
745 | caused a core dump on other operating systems.) | |
c4c30b20 | 746 | |
1daf7585 TT |
747 | Fix NLS bug in e2fsck, by avoiding trying to expand an empty string |
748 | (the NLS library will replace "" with the .po header information). | |
749 | ||
c4c30b20 TT |
750 | Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core |
751 | dump due to a division by zero error. (Addresses Debian bug #207082) | |
752 | ||
151a7162 TT |
753 | Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem |
754 | when reconnecting a directory requires creating a lost+found | |
755 | directory. (Addresses Debian bug #219640). | |
756 | ||
757 | Fixed a bug where e2fsck would bomb out if a journal needed to be | |
758 | replayed when using an alternate superblock. | |
759 | ||
48301129 | 760 | E2fsck will give an extra grace period before actually forcing a check |
c4c30b20 TT |
761 | if the laptop is running on battery. The next time fsck runs while |
762 | the system is on the AC mains, or after the grace period is exceeded, | |
763 | the filesystem will be checked. (Addresses Debian bug #205177) | |
764 | ||
765 | E2fsck will inform the user when there are 5 or fewer mounts before a | |
766 | filesystem check will be forced. (Addresses Debian bug #157194) | |
767 | ||
768 | Fix e2fsck's handling of corrupted indirect blocks in the bad block. | |
769 | We now correctly handle the case where there is an overlap between a | |
770 | block group descriptor or a superblock and a bad block indirect block. | |
771 | In the case where the indirect block is corrupted, we now suggest | |
772 | "e2fsck -c". | |
773 | ||
1daf7585 TT |
774 | Fix byte swap bugs in e2fsck that caused the journal backup location |
775 | in the superblock and symlinks created by SE Linux to be cleared | |
776 | by e2fsck on big-endian machines. (Addresses Debian bug #228723) | |
777 | ||
c4c30b20 TT |
778 | E2fsck -c now replaces the current list of bad blocks with the ones |
779 | found by badblocks. | |
780 | ||
781 | Fix bugs in e2fsck and tune2fs which could cause a core dump if a | |
782 | non-existent LABEL or UUID specifier is to e2fsck or tune2fs. | |
783 | ||
784 | Fix a potential bug in e2fsck which could cause it to core dump when | |
785 | trying to print the location of the backup superblock. | |
786 | ||
787 | Protect against a potential core dump in e2fsck when printing a | |
788 | message about backup superblocks. | |
858dd7b1 | 789 | |
6826bde5 TT |
790 | Add support for backing up the journal inode location in the |
791 | superblock. E2fsck will automatically save the journal information in | |
792 | the superblock if it is not there already, and will use it if the | |
793 | journal inode appears to be corrupted. ext2fs_add_journal_inode() | |
794 | will also save the backup information, so that new filesystems created | |
795 | by mke2fs and filesystems that have journals added via tune2fs will | |
796 | also have journal location written to the superblock as well. | |
797 | Debugfs's logdump command has been enhanced so that it can use the | |
798 | journal information in the superblock. | |
c4c30b20 TT |
799 | |
800 | E2fsck will now update all superblocks when moving the journal inode. | |
6826bde5 TT |
801 | |
802 | Shrink the size of the e2fsck executable by moving some initialized | |
803 | variables to the BSS segment. | |
804 | ||
805 | E2fsck will avoid printing the ^A and ^B characters which bracket the | |
806 | progress bar when stdout and stdin are a tty device instead of a pipe | |

809 | Debugfs's mkdir command will automatically expand the directory if |
810 | necessary. (Addresses Debian Bug: #217892) | |
811 | ||
812 | Fixed a bug in debugfs so that copying a file from /dev/null uses the | |
813 | correct mode bits. (Addresses Debian Bug: #217456) | |
814 | ||
815 | If the environment variables DEBUFS_PAGER and PAGER are not set, | |
816 | debugfs now searches for the appropriate pager to use, beginning with | |
2b5ddd75 | 817 | /usr/bin/pager, and then falling back to 'more' and 'less'. |
1daf7585 TT |
818 | (Addresses Debian bug #221977) |

48301129 TT |
823 | Fix debugging printf in resize2fs. (Addresses Debian Bug #271605) |

826 | Debian bug #225188) | |
151a7162 | 827 | |
858dd7b1 TT |
828 | Fix regression tests so they work correctly when e2fsprogs is compiled |
829 | with configure --disable-htree. | |
830 | ||
1daf7585 TT |
831 | Fix bug in uuid library when there is no network card and the library |
832 | is generating a time-based uuid. The random MAC address was not | |
833 | correctly generated to be a multicast address. | |
834 | ||
858dd7b1 | 835 | Add compile_et extensions from Heimdall that were missed the first time |
48301129 | 836 | around. |
858dd7b1 TT |
837 | |
838 | Fix bug in badblocks when using O_DIRECT; we need to make sure that | |
839 | we're reading from an offset which is page aligned. For read-only and | |
840 | read-write tests, we try to recover after an error so that we can | |
841 | continue reading on page-aligned boundaries. (Addresses Debian Bug | |
842 | #203713) | |

854 | Programmer's notes: | |
855 | ------------------- | |
856 | ||
b70b1167 TT |
857 | Fixed a build problem so that e2fsprogs would compile with the |
858 | --enable-profile option to configure selected. (Addresses Sourceforge | |
859 | bug #811408) | |
860 | ||
861 | Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat | |
862 | Bugzilla Bug #112448) | |
863 | ||
c4c30b20 TT |
864 | Centralize code which calculates the location of the superblock |
865 | and block group descriptors so that it is in a single library routine. | |
866 | ||
6826bde5 TT |
867 | Added two new functions, ext2fs_file_open2() and |
868 | ext2fs_inode_io_intern2() which take a pointer to an inode structure. | |
869 | ||
870 | Fix compile_et to output the correct prototype for | |
871 | initialize_xxx_err_table_r() in the header file. (Addresses Debian | |
872 | bug #204332) | |
873 | ||
874 | In the lib/et makefile, make sure com_err.info is deleted on "make clean". | |
875 | ||
858dd7b1 TT |
876 | Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if |
877 | present. This is for when we try stuffing an int into void * pointer. | |
878 | ||
879 | Fix type-punning which can cause gcc 3.x to miscompile code by getting | |
880 | confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(), | |
881 | and ext2fs_resize_mem() all now take a 'void *' instead of a 'void | |
882 | **'. The EVMS code uses an ugly union approach since we don't want to | |
883 | modify the EVMS interfaces. | |
884 | ||
885 | Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to | |
886 | aid build process on systems can use invoke GNU make as "gmake". | |
887 | ||
c4c30b20 TT |
888 | Added regression testing for mke2fs. |
889 | ||
890 | Fixed gcc -Wall nitpicks. | |
891 | ||
1daf7585 TT |
892 | Fixed various compiler warnings. |
893 | ||
894 | Add portability fixes for FreeBSD and for using fsctl under Darwin to | |
895 | support ext2 ioctl's. | |
896 | ||
858dd7b1 | 897 | |
9c7ec178 TT |
898 | E2fsprogs 1.34 (July 25, 2003) |
899 | =============================== | |
900 | ||
901 | Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in | |
902 | a tight loop while waiting for a child fsck to exit in some cases. | |
903 | This burns CPU times which slows down the low-level filesystem check. | |
904 | ||
905 | Added code to mke2fs to assure that the default block size for a | |
906 | filesystem is at least as big as the sector size of the device, if it | |
907 | can be determined. | |
908 | ||
909 | Changed mke2fs and resize2fs to round the default size of a filesystem | |
910 | to be an even multiple of the VM pagesize in order to avoid a Linux | |
911 | kernel bug introduced when the storage of the buffer cache was moved | |
912 | into the page cache. | |
913 | ||
914 | Mke2fs will warn the user when creating a filesystem with journaling | |
915 | and a blocksize greater than 4096. (Addresses Debian bug #193773) | |
916 | ||
917 | Fixed a bug in resize2fs which caused it to fail on filesystems with a | |
918 | non-empty bad block list. Resize2fs now discards any blocks on the | |
919 | badblock list which are no longer part of the filesystem as the result | |
920 | of a filesystem shrink. (Note: this means that shrinking and then | |
921 | enlarging a filesystem is no longer a reversible operation; | |
922 | information about bad blocks in the part of the filesystem which is to | |
923 | be chopped off will be lost.) | |
924 | ||
925 | Changed resize2fs so the user can use prefixes to specify the units of | |
926 | the new filesystem size (sectors, kilobytes, megabytes, or gigabytes), | |
927 | and to make the error and informational messages explicitly display | |
928 | the blocksize used by the filesystem, in order to avoid confusion. | |
929 | (Addresses Debian bug: #189814) | |
930 | ||
931 | Added a new debugfs command, dump_unused, which dumps the contents of | |
932 | all unused blocks to stdout. (Useful as an emergency try-to-find | |
933 | deleted data command.) | |
934 | ||
935 | Added a new debugfs command, imap, which prints the location of a | |
936 | specified inode in the inode table. | |
937 | ||
938 | Fixed a bug in the badblocks program which caused it to use one bit of | |
939 | randomness in its non-destructive read/write test, instead of using a | |
940 | full 8 bits of randomness. | |
941 | ||
942 | Added a new option (-t) to badblocks, which allows the user to control | |
943 | the test pattern(s) used when checking a disk. | |
944 | ||
945 | The blkid probe function now more correctly detects UDF filesystems. | |
946 | ||
947 | Fixed a bug in the blkid library which caused it to not update its | |
948 | cache if a filesystem changes from having a label to not having a | |
949 | label. | |
950 | ||
951 | Fixed a bug in the blkid library wihch could avoid an infinite loop | |
952 | in blkid_find_dev_with_tag() if /proc is not mounted and there the | |
953 | /etc/blkid.tab file has not yet been created. | |
954 | ||
955 | Fixed the badblocks program so that the destructive read/write test | |
956 | honors the -c option, and to use O_DIRECT when possible to avoid | |
957 | thrashing the system block buffer cache. | |
958 | ||
959 | Fixed various NLS issues. | |
c8a40402 | 960 | - Added Czech and Swedish translations |
9c7ec178 TT |
961 | - Removed testing NYC translation |
962 | - Fixed NLS support for message abbrevations in e2fsck | |
963 | - Remove de-utf.po, since we shouldn't have two versions using different | |
964 | charset encodings. | |
965 | - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to | |
966 | simplify the statistics reporting in e2fsck. | |
967 | ||
968 | Changed configure.in so that its defaults for *BSD systems no longer | |
969 | build an fsck wrapper, and not to install in /usr/local by default. | |
970 | ||
971 | Fixed some minor spelling errors/typo's in e2fsck and the configure | |
972 | script. | |
973 | ||
974 | Fixed various Debian packaging issues (see debian/changelog). | |
975 | ||
976 | Updated and clarified man pages. (Addresses Debian Bug #195616) | |
977 | ||
978 | Programmer's notes: | |
979 | ------------------- | |
980 | ||
981 | Fix gcc -Wall nitpicks. | |
982 | ||
983 | Updated gettext implementation used by e2fsprogs to 0.11.5, and enable | |
984 | NLS support by default. (Added partial workaround for gettext/Darwin | |
985 | incompatibility problems.) | |
986 | ||
987 | Added full MIT KRB5 and Himdall compaibility support to the com_err | |
988 | library and the compile_et program. (Addresses Debian bug #191900) | |
989 | ||
990 | Added the blkid_known_fstype() function to the blkid library, which | |
991 | returns true if it is passed a filesystem type which is recognized by | |
992 | the blkid probing functions. | |
993 | ||
994 | Improved the documentation for the blkid library. | |
995 | ||
996 | Added the ext2fs_get_device_sectsize() function the the ext2fs library, which | |
997 | returns the hardware sector size of a device, if it is available. | |
998 | ||
999 | Added a dependency in the blkid library's .so file to the uuid | |
1000 | library, since the former uses the latter. (Addresses Debian bug | |
1001 | #194094) | |
1002 | ||
1003 | Added --with-diet-libc and --disable-evms to the configure script. | |
1004 | ||
1005 | Fixed a minor memory leak in the badblocks program. | |
1006 | ||
1007 | Fixed a portability problem in tune2fs --- not all systems have strptime(). | |
1008 | ||
1009 | Fixed a portability problem in debugfs with the use of getopt() more | |
1010 | than once. Old-style BSD, new-style BSD, and Linux C libraries all do | |
1011 | things differently. | |
1012 | ||
1013 | Add support Windows support to ext2fs_get_device_size(). | |
1014 | ||
1015 | Added (normally disabled) debugging code to the Unix I/O manager which | |
1016 | causes it to disable all userspace caching if the NO_IO_CACHE is | |
1017 | defined. | |
1018 | ||
1019 | Changed the test I/O manager so it can always be linked into e2fsck, | |
1020 | mke2fs, and tune2fs if enabled via --enable-test-io-debug to the | |
1021 | configure script. The test I/O manager will only print any debugging | |
1022 | information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment | |
1023 | variables are set, which specifies which I/O operations are logged and | |
1024 | a block number to watch, respectively. The log messages are sent to | |
1025 | stderr by default, unless a filename is specified via the | |
1026 | TEST_IO_LOGFILE environment variable. | |
1027 | ||
1028 | ||
71df0dc3 | 1029 | E2fsprogs 1.33 (April 21, 2003) |
9c7ec178 | 1030 | =============================== |
508d7f3c | 1031 | |
ba142c1b TT |
1032 | Added a new utility program, logsave, which captures the output of a |
1033 | command in a log file, even if the containing directory hasn't been | |
1034 | mounted yet (in which case the it saves the output in memory until it | |
1035 | can write out the logfile). This is useful for capturing the | |
1036 | output of fsck during the boot sequence. | |
1037 | ||
1038 | Fixed some portability problems that were causing problems under | |
1039 | the Cygwin32 environment. | |
1040 | ||
1041 | Mke2fs now interprets a negative number to the -b option as a minimum | |
1042 | block size. | |
1043 | ||
1044 | Fixed a bug in mke2fs which was incorrectly checking the argument to | |
1045 | the -g option if the default block size was used. (Addresses Debian | |
1046 | bug #188319) | |
1047 | ||
1048 | Fsck now explicitly ignores tmpfs and devpts, and it will complain if | |
1049 | it can not find filesystem checkers for jfs, reseirfs, and xfs. | |
1050 | ||
1051 | E2fsck now updates the global free block and inode counters from the | |
1052 | block group specific counters quietly. This is needed for an | |
1053 | experimental patch which eliminates locking the entire filesystem when | |
1054 | allocating blocks or inodes; if the filesystem is not unmounted | |
1055 | cleanly, the global counts may not be accurate. | |
1056 | ||
1057 | Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS | |
1058 | 2.0 is not yet supported; this only pulled in the bug fixes: fixed | |
1059 | possible hangs caused by bugs in calling waitpid, and not setting the | |
1060 | pipe to non-blocking mode; also fixed a file descriptor leak; made | |
1061 | sure all functions call log entry/exit functions.) | |
1062 | ||
1063 | Badblocks now flushes its output file as bad blocks are discovered. | |
1064 | ||
1065 | The uuid library is now more paranoid about assuming the correctness | |
1066 | of the /dev/random device; it mixes in a stream of bytes from | |
1067 | random/srandom, just in case. | |
1068 | ||
39d38b05 | 1069 | Update Debian files to reflect the fact that I am now the Debian |
ba142c1b TT |
1070 | maintainer of e2fsprogs. Other various Debian-specific packaging |
1071 | cleanups. | |
39d38b05 TT |
1072 | |
1073 | Move the source tarball generation functions from the top-level | |
1074 | makefile to the util/gen-tarball script. | |
1075 | ||
1076 | Updated the Turkish .po translation file. | |
1077 | ||
1daf7585 | 1078 | Added Heimdal and MIT krb5 extensions to the com_err library to make |
39d38b05 TT |
1079 | it more compatible with com_err libraries from those distributions. |
1080 | ||
1081 | Changed dumpe2fs to always display the superblock fields relating to | |
1082 | the journalling and/or directory indexing feature even if those | |
1083 | features are not enabled. | |
1084 | ||
508d7f3c TT |
1085 | Updated and clarify copyright statement vis-a-vis alpha releases of |
1086 | e2fsprogs. | |
1087 | ||
1088 | The ss library will now try to dynamically link to the readline | |
1089 | library and use it if it is present in the system. This means that | |
ba142c1b TT |
1090 | the debugfs program now has line editing and history features. The |
1091 | SS_READLINE_PATH environment variable is used to find a readline or | |
1092 | readline-compatible library. | |
3809bf1d | 1093 | |
e5dced7f TT |
1094 | E2fsck now finds most duplicate filenames (all when rebuilding all |
1095 | directories via the -D option) and offers to delete or rename | |
1096 | duplicate filenames/directory entries. (Addresses Debian Bug #176814). | |
1097 | ||
1098 | Fix bug in e2image. When writing out a raw image file, include data | |
1099 | blocks from symlinks that do not store the symlink within the inode. | |
1100 | ||
3809bf1d TT |
1101 | Fix bug in resize2fs which incorrectly moved the block and inode |
1102 | bitmaps for sparse superblock filesystems and incorrectly marked | |
1103 | blocks as in use. (Addresses Debian bug #174766) | |
1104 | ||
1105 | Added a new shared library, the blkid library, which efficiently | |
1106 | allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL | |
1107 | and UUID filesystem specifiers without needing to search all of the | |
1108 | devices in the system. Instead, the device is looked up in a cache | |
1109 | file, and then verified to make sure the blkid cache is correct. | |
1110 | ||
1111 | Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for | |
1112 | the device name, using the blkid library. (Addresses Debian bugs | |
1113 | #166048, #179671) | |
1114 | ||
1115 | Fsck now supports backslash escapes in /etc/fstab so that \040 can be | |
1116 | used for spaces in device labels. | |
1117 | ||
1118 | Removed 32-bit limitations for debugfs's dump command. | |
1119 | ||
1120 | If the user specifies a large number of inodes, Mke2fs will | |
1121 | automatically adjust the number of blocks per group to find a valid | |
1122 | set of filesystem parameters. | |
1123 | ||
1124 | Add workaround to detect broken MD devices where when some of the | |
1125 | underlying devices are marked read-only, writes to the MD device are | |
1126 | silently dropped. E2fsck will detect if there is an attempt to run | |
1127 | the journal twice, and abort with an error if this is the case. | |
1128 | (Addresses IBM Bugzilla bug #1226) | |
1129 | ||
1130 | E2fsck will print an error if more than one of the -p/-a, -n or -y | |
1131 | options are specified. | |
1132 | ||
1133 | E2fsck will fix HTREE corruptions in preen mode, without stopping the | |
1134 | boot process. This is needed because the 2.4 ext2 filesystem | |
1135 | accidentally had the INDEX_FL backwards compatibility code removed. | |
1136 | ||
1137 | Mke2fs no longer creates filesystems with the dir_index flag set by | |
1138 | default; the user has to specifically request it. | |
1139 | ||
1140 | Update and clarified various man pages. (Addresses Debian bugs | |
ba142c1b | 1141 | #173612, #175233, #175113, and #170497, #185945, #188318) |
3809bf1d | 1142 | |
508d7f3c TT |
1143 | Created man page for the mk_cmds program (from the libss library). |
1144 | ||
3809bf1d TT |
1145 | Programmer's notes: |
1146 | ------------------- | |
1147 | ||
1148 | Fix various gcc -Wall nits. | |
1149 | ||
1150 | Fixed a lot of portability problems that caused e2fsprogs not to build | |
e5dced7f TT |
1151 | successfully under Solaris and Apple/Darwin. |
1152 | ||
1153 | Fixed a Makefile dependency to allow building e2fsprogs using parallel | |
1154 | make jobs. | |
3809bf1d TT |
1155 | |
1156 | Changes to create a subset distribution which consists only of the | |
1157 | et, ss, uuid, and blkid libraries. The configure script and top-level | |
1158 | makefile were changed to support working with a subset distribution. | |
1159 | ||
ba142c1b TT |
1160 | Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not |
1161 | actually used, and might people who are looking for | |
1162 | EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use. | |
1163 | ||
508d7f3c TT |
1164 | Updated debian files to fix a number of Lintian warnings. |
1165 | ||
1166 | Updated config.guess and config.sub with newer versions from the FSF. | |
3809bf1d | 1167 | |
71df0dc3 TT |
1168 | Removed unnecessary libraries from being linked into the fsck, lsattr, |
1169 | chattr, and blkid executables. | |
1170 | ||
38513011 TT |
1171 | E2fsprogs 1.32 (Nomvember 9, 2002) |
1172 | ================================== | |
1173 | ||
1174 | Fixed a bug in the Unix I/O routines which caused needless writebacks | |
1175 | of clean blocks from the unix_io cache (they were erroneously marked | |
1176 | as being dirty, so they were getting written back to disk before | |
1177 | getting evicted from the disk cache). This was harmless, but it | |
1178 | significantly slowed down e2fsck. | |
1179 | ||
1180 | Made some other minor optimizations to the Unix I/O routines to save a | |
1181 | small amount of CPU time. | |
1182 | ||
1183 | Updated internationalization files. | |
1184 | ||
3809bf1d | 1185 | |
ae65b29f TT |
1186 | E2fsprogs 1.31 (Nomvember 8, 2002) |
1187 | ================================== | |
1188 | ||
1189 | Update EVMS ext2fsim plugin with EVMS 1.2. (We still support | |
1190 | compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error | |
1191 | handling for child process that die unexpectly. Add a hack to force | |
1192 | mkfs to create filesystems that won't cause problems with hardware | |
1193 | that has 2k or 4k minimum blocksize requirements. Read from child | |
1194 | processes in non-blocking mode, so that the GUI continues to update. | |
1195 | ||
1196 | Fix e2fsck so that it returns the appropriate exit code when the root | |
1197 | filesystem has been changed, so that system's rc scripts will be told that | |
1198 | the system needs to be rebooted. | |
1199 | ||
1200 | Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag | |
1201 | was set, some of the descriptor blocks that should have been written | |
1202 | out were getting skipped. | |
1203 | ||
1204 | Changed e2fsck to force out changes to the backup copies of the | |
1205 | superblock and block group descriptors when important changes are made | |
1206 | to those data structures. | |
1207 | ||
1208 | Fix a bug where e2fsck could erroneously mark a filesystem as being | |
1209 | clean if a check of dirty filesystem is interrupted with a ^C. (Bug | |
1210 | introduced in e2fsprogs 1.28.) | |
1211 | ||
1212 | If journal debuging is enabled using --enable-jbd-debug, the debugging | |
1213 | level is now set via the E2FSCK_JBD_DEBUG environment variable. | |
1214 | ||
1215 | If byteswapping support is disabled using configure --disable-swapfs, | |
1216 | skip the tests which depend on byte-swapping, so that "make check" | |
1217 | won't bomb out. | |
1218 | ||
1219 | Lshattr will now display the indexed directory flag. Also, some of | |
1220 | the more esoteric compression flags are supressed unless compression | |
1221 | support has been enabled. | |
1222 | ||
1223 | Update man pages. | |

1226 | E2fsprogs 1.30 (October 31, 2002) |
1227 | ================================= | |
1228 | ||
1229 | When resizing a filesystem, and inodes need to moved, resize2fs will | |
1230 | update the inode's ctime field, and the mtime field of the containing | |
1231 | directories, so that incremental backups using dump/restore will work | |
1232 | correctly. | |
1233 | ||
1234 | In order to avoid spurious errors, e2fsck wil check the last | |
1235 | superblock write time to determine whether or not it can safely use | |
1236 | the LOW_DTIME checks to determine if there are inodes on the orphan | |
1237 | inode linked list that had somehow gotten disconnected. (Addresses | |
1238 | Sourceforge bug #620980) | |
1239 | ||
1240 | Partition in /proc/partitions that being with the string "lvm" are | |
1241 | considered real partitions even if they do not end with a number. | |
1242 | ||
1243 | Fixed a bug in the the uuid generation function, where if /dev/urandom | |
1244 | is not present, but /dev/random is, and there isn't sufficient | |
1245 | entropy, the get_random_byte function could spin a loop forever. | |
1246 | ||
1247 | E2fsck, mke2fs, etc. will now reliably notice when image files are | |
1248 | mounted using the loopback interface. (Addresses Sourceforge bug | |
1249 | #619119) | |
1250 | ||
1251 | When flushing buffers (as is done by badblocks, for example) check to | |
1252 | see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the | |
1253 | FDFLUSH ioctl which causes the MD device driver which causes confusing | |
1254 | syslog messages about obselete ioctl messages. (Addresses Sourceforge | |
1255 | bug #545832). | |
1256 | ||
1257 | Debugfs's write command now checks to see if the destination filename | |
1258 | exists before creating it. (Addresses Sourceforge bug #478195.) | |
1259 | ||
1260 | When installing man pages, search for compressed man pages using all | |
1261 | commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.) | |
1262 | ||
1263 | Fixed a bug in fsck where multiple filesystems specified on the | |
1264 | command were not being checked in parallel due to a logic bug | |
1265 | introduced to support the FSCK_MAX_INST environment variable. | |
1266 | ||
1267 | We have added a new superblock field, s_mkfs_time, which indicates | |
1268 | when a filesystem was created. It is set via mke2fs, and printed out | |
1269 | by dumpe2fs, but is not actually touched by the kernel. | |
1270 | ||
1271 | Dumpe2fs has been made more robust by not aborting if there is an | |
1272 | error reading the block/inode bitmaps; instead it will still print out | |
1273 | the location of the block/inode bitmaps and inode table. | |
1274 | ||
1275 | Add support for the an alternative block group descriptor layout which | |
1276 | allows for on-line resizing without needing to prepare the filesystem | |
1277 | in advance. (This is the incomat feature flag meta_bg.) | |
1278 | ||
1279 | Add support for storing default mount options in the superblock, so | |
1280 | that the filesystem can be mounted with specific mount options without | |
1281 | needing to specify them on the mount command line or in the /etc/fstab | |
1282 | file. | |
1283 | ||
1284 | Add support for a new inode flag, which is to be used for indicating | |
1285 | the top of directory hierarchies for the Orlov block allocator. | |
1286 | ||
1287 | Fix e2fsck so that if it creates the lost+found directory, it does so | |
1288 | with the more apporpriate permissions of 0700. Also change | |
1289 | mklost+found so that it also creates the directory 0700. | |
1290 | ||
1291 | Fixed format bug in e2fsck if NLS is in use. | |
1292 | ||
1293 | Add a German translation for e2fsprogs's NLS support. | |
1294 | ||
1295 | Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at | |
1296 | the beginning of the inode table. This won't matter much, since if | |
1297 | there is a bad block at the beginning of the inode table, the root | |
1298 | directory won't be available. But at least e2fsck won't crash in this | |
1299 | case. | |
1300 | ||
1301 | Fixed endian problems in the htree code for e2fsck and debugfs. | |
1302 | ||
1303 | When byte-swapping a filesystem on a PPC architecture, byte-swap the | |
1304 | bitmaps since the historical big-endian ext2 variant had byte-swapped | |
1305 | bitmaps, and the ext2fs library assumes this. This fixes the | |
1306 | regression test suite on PPC machines. | |
1307 | ||
1308 | Fix e2image so that it handles a bad block in the inode table | |
1309 | appropriately. | |
d5e7810e TT |
1310 | |
1311 | E2fsck now uses a more sophisticated algorithm to salvage corrupted | |
1312 | directories that recovers more information in the corrupted directory | |
1313 | block. | |
1314 | ||
1315 | E2fsck now performs additional consistency checks on indexed (HTREE) | |
1316 | directories. | |
1317 | ||
1318 | Fix bug where efsck might get confused about whether a completely | |
1319 | empty directory block is an empty leaf block or an interior htree | |
1320 | node. This could cause e2fsck to get confused into think that a valid | |
1321 | indexed directory was corrupted. | |
1322 | ||
1323 | E2fsck no longer creates an empty directory entry at the end of a | |
1324 | directory block when optimizing a directory. This would cause some | |
1325 | earlier versions of the dxdir kernel code to corrupt the directory | |
1326 | when attempting to split a node containing an empty directory entry. | |
1327 | ||
1328 | E2fsck could sometimes in rare circumstances leave the indexed flag | |
1329 | set after a small directory was optimized by compressing it instead of | |
1330 | indexing it. (This should never happen in real life, since | |
1331 | directories that small wouldn't have been indexed, but better safe | |
1332 | than sorry.) | |
1333 | ||
1334 | E2fsck now only updates the master superblock in all cases. This | |
1335 | slightly shortens its run time. | |
1336 | ||
1337 | Ext2ed can deal with directory entries of length 0; previously it | |
1338 | would get stuck in an infinite loop. | |
1339 | ||
1340 | Fsck now has support for reiserfs volumes when parsing LABEL= and UUID= | |
1341 | specifiers. (Sourceforge patch #613447) | |
1342 | ||
1343 | Badblocks will now work correctly on read-only devices such as | |
1344 | CD-ROM's. (Sourceforge patch #600451) | |
1345 | ||
5d823a47 | 1346 | Updated and clarified man pages. (Addresses Debian bug #167108) |

1349 | E2fsprogs 1.29 (September 24, 2002) |
1350 | =================================== | |
1351 | ||
1352 | Fixed a bug in e2fsck which could corrupt a directory when optimizing | |
1353 | it (via the -D option) or rebuiliding the hash tree index with a 1 in | |
1354 | 512 probability, due to a fence post error. | |
1355 | ||
1356 | Fixed a bug in the LVM support code which caused LABEL='xxx' not to | |
1357 | work correctly. | |
1358 | ||
1359 | Mke2fs now enables the directory indexing flag by default. (Since | |
1360 | this is a compatible feature flag, it's safe to do so.) | |
1361 | ||
1362 | Tune2fs will support setting the directory indexing feature flag. It | |
1363 | will automatically set up the default hash algorithm and hash seed | |
1364 | fields in the superblock. | |
1365 | ||
1366 | If the bone-headed user enters the root filesystem twice in | |
1367 | /etc/fstab, the -R option which skips the root filesystem will skip | |
1368 | all of them. (Addresses Debian bug #159423). Note! This is not a | |
1369 | precedent for dealing intelligently with any other kind of doubled | |
1370 | entry in /etc/fstab! | |
1371 | ||
1372 | ||
1373 | Programmer's notes: | |
1374 | ------------------- | |
1375 | ||
1376 | Removed perror declaration in lib/et/internal.h. All modern systems | |
1377 | can be expected to define perror() these days. Besides, the lib/et | |
1378 | code wasn't using perror at all anyway. :-) | |
1379 | ||
1380 | ||
b7bad615 TT |
1381 | E2fsprogs 1.28 (August 31, 2002) |
1382 | ================================ | |
1383 | ||
1384 | Add support for the Hashed-Tree Directory Indexing to e2fsck. Support | |
1385 | for setting the htree flag is not included yet, although it can be | |
1386 | manually turned on via the debugfs program. | |
1387 | ||
1388 | Clarified e2fsck error message which is printed when it cannot find | |
1389 | sufficient contiguous block when relcating filesystem metadata. | |
1390 | ||
1391 | Added support for building an EVMS plugin module for ext2/3. This | |
1392 | module is substantially the same as the EVMS module shipping with EVMS | |
1393 | 1.1, with one or two bugfixes. E2fsprogs can also build this plugin | |
1394 | for use with EVMS 1.0 (which did not include the ext2 plugin module), | |
1395 | if the configure --enable-old-evms flag is given. | |
1396 | ||
1397 | Fsck will search through EVMS volumes when trying to resolve | |
1398 | filesystem specifications such as LABEL=xxx or UUID=xxx. | |
1399 | ||
1400 | Added a new utility program, /sbin/findfs, which will return | |
1401 | filesystem specifications such as LABEL=xxx or UUID=xxx, and prints | |
1402 | the device name. | |
1403 | ||
1404 | Update and clarified various man pages. (addresses Debian Bug #145044, | |
1405 | #146437, #131350, #151990, #144621, #141938) | |
1406 | ||
1407 | If there are no filesystems specified on fsck's command line, fsck now | |
1408 | treat that as if the -As options were given. Previously it would | |
1409 | simply do nothing. (Addresses Debian Bug #153102) | |
1410 | ||
1411 | Mke2fs no longer treats a failure to be able to clear the MD signature | |
1412 | at the end of the filesystem as a fatal error. (Addresses Debian Bug | |
1413 | #155007) | |
1414 | ||
1415 | The e2p library functions (which are used by lsattr and chattr) now | |
1416 | double check to make sure the file is a regular file or directory | |
1417 | before attempting to use the ext2 ioctls. Some device drivers | |
1418 | unfortunately respond to the ext2 ioctl's with unknown behaviour. | |
1419 | (Addresses Debian Bug #152029). | |
1420 | ||
1421 | The extended attribute handling has been updated to correspond with | |
1422 | the latest V2 bestbits ACL code. | |
1423 | ||
1424 | Fixed bug in e2fsck which caused it to not clear the dtime field when | |
1425 | processing truncated inodes on the orphan list. This could cause data | |
1426 | loss(!) if a filesystem is rebooted before a truncate has been | |
1427 | committed. | |
1428 | ||
1429 | E2fsck now uses red/black trees in pass1b, which removes some O(n**2) | |
1430 | algorithms. This makes e2fsck much faster in the case of severely | |
1431 | corrupted filesystems where a large number of blocks are claimed by a | |
1432 | large number of inodes. (Thanks to the 2.5 IDE device driver for | |
1433 | inspiring this work.) | |
1434 | ||
1435 | Resize2fs has been significantly sped up when shrinking and expanding | |
1436 | a filesystem by a very small number of blocks (for example, when EVMS | |
1437 | is converting a partition to be an EVMS legacy volume). | |
1438 | ||
1439 | Added a new option to e2fsck, -D, which will optimize or compress all | |
1440 | of the directories in the filesystem. | |
1441 | ||
1442 | E2fsck now catches SIGINT and SIGTERM to make sure it will can | |
1443 | properly clean up and only exit at safe points. Fsck will pass | |
1444 | SIGINT/SIGTERM to its child processes, and wait until they have all | |
1445 | exited before it exits. | |
1446 | ||
1447 | The uuid parsing code in the uuid library now properly complains when | |
1448 | an illegally formated uuid is presented to it. (Addresses Debian bug | |
1449 | #152891) | |
1450 | ||
1451 | Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10 | |
1452 | and 2.4.17, since the workaround can cause problems when using a 2.4 | |
1453 | kernel with an old version of glibc built with the 2.2 headers. | |
1454 | ||
1455 | Fixed a bug in mke2fs where it wasn't properly clearing the initial | |
1456 | superblock used by other filesystems. (Addresses Debian bug #147256.) | |
1457 | ||
1458 | Added support for the synchronous directory feature written by Andrew | |
1459 | Morton. | |
1460 | ||
1461 | The debugfs program can delete directories using the rmdir command. | |
1462 | ||
1463 | Add support for 8k and 16k filesystems (for systems with page sizes | |
1464 | that are greater or equal to 8k or 16k, respectively). Note that | |
1465 | these filesystems can not be mounted on x86 systems, or other systems | |
1466 | with only 4k page sizes, due to limitations in the current Linux VM | |
1467 | code. | |
1468 | ||
1469 | Resize2fs requires that the filesystem state be valid and have no | |
1470 | errors; otherwise, e2fsck -f must be run first. (Previously it simply | |
1471 | required that the last fsck time be greater than the last mount time.) | |
1472 | ||
1473 | Configure now defaults the man pages directory to /usr/share/man on | |
1474 | Linux systems. | |
1475 | ||
1476 | E2fsck now offers to truncate inodes which contain too many blocks (so | |
1477 | that i_blocks would overflow. Also fixed handling of large sparse | |
1478 | files. | |
1479 | ||
1480 | E2fsck now more completely checks for symlink validity, including | |
1481 | requiring NULL termination and length checks. | |
1482 | ||
1483 | E2fsck will offer to try forcing a disk write to remap a bad block | |
1484 | after finding a read error when reading a filesystem metadata block. | |
1485 | ||
1486 | Fixed a bug in debugfs which caused the -b and -s options to crash | |
1487 | debugfs, as well as breaking the testb, setb, and clearb functions. | |
1488 | ||
1489 | Added a bmap command to debugfs which calculates the logical to | |
1490 | physical block mapping for a particular inode. | |
1491 | ||
1492 | Fixed a bug in code which checked to see if a device was mounted which | |
1493 | sometimes (rarely) failed in the case of a plain file. | |
1494 | ||
1495 | Fixed a bug in resize2fs where when it reported an error, it would | |
1496 | print a message erroneously indicating that the filesystem had been | |
1497 | resized before it aborted. | |
1498 | ||
1499 | When resizing a plain file which is smaller than the requested size, | |
1500 | resize2fs will attempt to extended the file so that programs like | |
1501 | e2fsck will not complain that the file is too small. | |
1502 | ||
1503 | Resize2fs will print the actual new size of the filesystem when it is | |
1504 | finished resizing. | |
1505 | ||
1506 | Fixed a bug in debugfs where "ls -l" would report incorrectl file type | |
1507 | information on big-endian systems. | |
1508 | ||
1509 | ||
1510 | Programmer's notes: | |
1511 | ------------------- | |
1512 | ||
1513 | Fixed collisions with C++ reserved words. | |
1514 | ||
1515 | Added portability fixes for building e2fsprogs on the HURD and AIX. | |
1516 | ||
1517 | Added the ext2ed program for creation of test cases. (ext2ed has many | |
1518 | limitations and bugs which make it unsuitable for production use.) | |
1519 | ||
1520 | The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new | |
1521 | flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the | |
1522 | name_len field is byte swampped on big-endian machines, since in the | |
1523 | V2 structure, name_len is a char field which is doesn't need to be | |
1524 | byte swapped --- except if an old-style kernel had byte-swapped the | |
1525 | name_len field as part of the V1 structure. | |
1526 | ||

a8e77249 TT |
1528 | E2fsprogs 1.27 (March 8, 2002) |
1529 | ============================== | |
1530 | ||
1531 | The warning messages for mke2fs now go to standard error. | |
1532 | ||
1533 | Fixed to make sure "make check" runs all of the test programs with | |
1534 | LD_LIBRARY_PATH set, so that we test the libraries in the build tree. | |
1535 | ||
1536 | The mke2fs program checks the boot sector for the BSD disk label, and | |
1537 | avoids erasing it if it is there. | |
1538 | ||
1539 | Fixed a bug in e2fsck which caused it to core dump if the journal | |
1540 | inode was missing when it was supposed to be there. | |
1541 | ||
1542 | E2fsck now prints ranges in pass 5 when printing deltas for the block | |
1543 | and inode bitmaps. | |
afa14ba0 TT |
1544 | |
1545 | Debugfs's "ls -l" command now will print out the file type information | |
1546 | in the directory entry. | |
1547 | ||
1548 | Create man pages and hard links for fsck.ext3 and mkfs.ext3. If | |
1549 | mke2fs is invoked as mkfs.ext3, create the filesystem with a journal. | |
1550 | ||
1551 | Debugfs can now examine the experimental directory indexing | |
1552 | information. | |
1553 | ||
a471ac52 TT |
1554 | Fixed bug in debugfs which caused it to core dump if modify_inode is |
1555 | called without an open filesystem. | |
1556 | ||
1557 | The debugfs lsdel command now runs its output through a pager first. | |
1558 | ||
afa14ba0 TT |
1559 | When installing manual pages, remove the compressed manual pages first. |
1560 | ||
1561 | Synchronized with Debian's packaging information for e2fsprogs-1.26-1. | |
1562 | ||
1563 | Fix the 2.4 resource limitation workaround introduced in 1.26 which | |
1564 | actually broke things on mips32, sparc32, and Alpha platforms. | |
1565 | ||
a471ac52 TT |
1566 | Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made |
1567 | (which is required by the newer libintl libraries). | |

afa14ba0 TT |

1572 | Fixed various gcc -Wall complaints. |
1573 | ||
afa14ba0 TT |
1574 | Fixed a few memory leaks in the e2fsck journaling code, and in the |
1575 | ismounted code checking for a swap device. | |
1576 | ||
1577 | Add new inode I/O abstraction interface which exports an inode as | |
1578 | an I/O object. | |
1579 | ||
1580 | Exported ext2_file_flush as a public interface. | |
1581 | ||
1582 | In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer. | |
1583 | ||
1584 | Lots of small random portability fixes to make e2fsprogs build under | |
1585 | AIX --- even without the 5L compatibility toolkit, and even using the | |
1586 | uber-crippled AIX native C compiler. | |

1592 | Dumpe2fs will keep going now if the bad block inode can't be read. |
1593 | (Previously it stopped with a fatal error.) | |
1594 | ||
1595 | E2fsck will now give an opportunity to run the journal even if the | |
1596 | recovery flag is not set. This is the default behaviour if e2fsck is | |
1597 | using a backup superblock, since the needs_recovery flag will never be | |
1598 | set in the backup superblock copies. | |
1599 | ||
1600 | E2fsck now automatically finds the backup superblock/group descriptors | |
1601 | even when the primary superblock is completely destroyed for 2k and 4k | |
1602 | filesystems. (Previously it just guessed/assumed that we were dealing | |
1603 | with a 1k filesystem in that case, and users had to manually specify | |
1604 | the backup superblock number.) | |
1605 | ||
1606 | Fixed a bug in e2fsck where it dereferences a null pointer when there | |
1607 | is a problem opening a filesystem in preen mode. | |
1608 | ||
1609 | E2fsck now handles external journals correctly; previously it trashed | |
1610 | the external journal device if the journal needed to be replayed. | |
1611 | ||
1612 | Work around ulimit incompatibility problem caused by recent 2.4 | |
1613 | kernels; the unix IO module will automatically try to set any resource | |
1614 | limits to be infinite on startup. | |
1615 | ||
cd1a79a5 TT |
1616 | Fixed a bug in e2fsck where it wasn't allocating a new block or inode |
1617 | bitmap if it wasn't present and the blocksize was 2k or 4k. | |
9c7ec178 | 1618 | (Addresses Debian Bug #116975) |
cd1a79a5 TT |
1619 | |
1620 | E2fsck will check and fix botched ext3 V1 to V2 superblock updates by | |
1621 | clearing the new V2 fields if they do not make sense or if the ext3 | |
1622 | superblock is version 1 superblock. | |
1623 | ||
1624 | E2fsck will automatically relocate the ext3 journal from a visible | |
1625 | file (i.e., /.journal) to an hidden inode if the filesystem has been | |
1626 | opened read/write. This allows the users to add a journal while the | |
1627 | filesystem is mounted, but the next time the system is rebooted, the | |
1628 | journal file will disappear. This avoids problems with backups, | |
1629 | stupid operators with superuser bits, etc. | |
1630 | ||
1631 | Fix a bug in fsck where it would not support a filesystem type of | |
1632 | "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx. | |
1633 | ||
a5f3f5c1 TT |
1634 | Fsck now supports fstab entries of the form "ext3,ext2". It will also |
1635 | automatically identify reiserfs filesystems. | |
1636 | ||
1637 | The number of processes spawned by fsck can now be limited using the | |
1638 | FSCK_MAX_INST environment variable. | |
1639 | ||
446314fc TT |
1640 | Fsck now searchs the LVM proc hierarchy to find logical volumes which |
1641 | should be searched for UUID and label information. | |
1642 | ||
cd1a79a5 TT |
1643 | Work around a bug in 2.4.10+ kernels by trying to unset the filesize |
1644 | limit if at all possible, when opening a block device. (The filesize | |
1645 | limit shouldn't be applied against writes to a block device.) | |
1646 | ||
446314fc TT |
1647 | In mke2fs and e2fsck, specifying the -c option twice will now do |
1648 | a read/write test on the disk. Update the man pages to encourage | |
1649 | using the -c option, and to discouraging running badblocks separately, | |
1650 | since users tend to forget to set the blocksize when running | |
1651 | badblocks. | |
1652 | ||
cd1a79a5 TT |
1653 | Mke2fs now automatically clears the immutable attribute on a |
1654 | pre-existing .journal file left over from a previous failed attempt to | |
1655 | add a journal to an alreadyy-mounted filesystem. | |
1656 | ||
1657 | Fixed mke2fs's exit codes to consistently indicate when the mke2fs | |
1658 | operation failed. | |
1659 | ||
446314fc TT |
1660 | Mke2fs now creates the lost+found directory with permissions of 0700, |
1661 | so that files that had previously lived in protected directory are | |
1662 | safe if they get dropped in lost+found and the system administrator | |
1663 | doesn't deal with immediately. (Addresses Debian #bug 118443) | |
1664 | ||
1665 | Mke2fs and e2fsck (and all programs that use the | |
1666 | ext2fs_check_if_mounted function) will now properly identify that a | |
1667 | device is mounted, even in cases where devfs has confused things with | |
1668 | multiple devices names with the same identity, or if a dim-witted | |
1669 | system administrator has done something stupid like creating device | |
1670 | file aliases in their home directory. Also now checks for swap devices | |
1671 | by using /proc/swaps. (Addresses Debian bug #106622) | |
1672 | ||
a5f3f5c1 TT |
1673 | Added a new option (-T) to tune2fs which sets the time a filesystem |
1674 | was last checked. | |
1675 | ||
cd1a79a5 TT |
1676 | Speed up e2image when creating sparse raw image files by optimizing |
1677 | away excess lseek() system calls. | |
1678 | ||
1679 | Fix support of large (> 2GB) files when used as a filesystem in | |
1680 | mke2fs, tune2fs, debugfs, and findsuper. | |
1681 | ||
1682 | Debugfs's stat and icheck commands now properly deals with large (> | |
1683 | 2GB) files. | |
1684 | ||
1685 | Debugfs's set_super_value command now prints out the list of valid | |
1686 | superblock fields which can be set using the command. | |
1687 | ||
446314fc TT |
1688 | Debugfs's rm and kill_file command now updates the superblock free block |
1689 | and inode counts, thus keeping the filesystem consistent. | |
1690 | ||
a5f3f5c1 TT |
1691 | Debugfs's lsdel command now takes an optional argument which allows |
1692 | the user to only see the most recently deleted files. | |
1693 | ||
1694 | A new command (undel) was added to debugfs which automates | |
1695 | undeleting a deleted inode and linking it back to a directory. | |
1696 | ||
1697 | Debugfs's ls command now takes a new option, -d, which lists | |
1698 | deleted directory entries. | |
1699 | ||
1700 | Debugfs's testb, freeb, setb, and find_free_block commands now take an | |
1701 | optional count argument. | |
1702 | ||
cd1a79a5 TT |
1703 | Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will |
1704 | be used to signal that a particular inode should not be eligible for | |
1705 | tail-merging --- this is needed for programs like LILO. | |
1706 | ||
1707 | The findsuper (an unreleased, uninstalled utility program) has been | |
1708 | improved to add extra validity checks and to add a progress meter. | |
1709 | (It is still an unsupported program; the officially supported way to | |
1710 | recover from a trashed partition table is to use gpart; findsuper is | |
1711 | for wizards only. :-) | |
1712 | ||
1713 | Debugfs was fixed to compile with "configure --disable-swapfs". | |
1714 | ||
446314fc | 1715 | Cleaned up various manual pages. (Addresses Debian bug #119624, #120171) |
cd1a79a5 TT |
1716 | |
1717 | Added new translation file for Turkish. | |
1718 | ||
446314fc TT |
1719 | Programmer's notes: |
1720 | ------------------- | |
1721 | ||
1722 | Fix general gcc -Wall complaints. | |
1723 | ||
1724 | E2fsprogs (mostly) works with the dietlibc. | |
1725 | ||
1726 | The programming texinfo file has been expanded to include description | |
1727 | of additional libext2fs functions. (Still not compeltely done, but a | |
1728 | lot of the more important functions have been documented.) | |
1729 | ||
1730 | Added a umask structure to struct_ext2_filsys, which currently only | |
1731 | modifies the behaviour of ext2fs_mkdir(), but if we add any file | |
1732 | creation functions to libext2fs, we should also make sure they respect | |
1733 | the umask setting. | |
1734 | ||
a5f3f5c1 TT |
1735 | The build-rpm script was fixed to be a bit more safe. |
1736 | ||
1737 | The tests' Makefile now has a way of automating test case creation | |
1738 | for e2fsck, using "make testnew". | |
1739 | ||
1740 | Created a new function, ext2fs_dir_iterate2 which passes more | |
1741 | information to the callback function (identical to the one used by | |
1742 | ext2fs_dblist_dir_iterate). The directory iterator functions take a | |
1743 | new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted | |
1744 | directory entries. If the directory entry is deleted, the callback | |
1745 | function will be called with the entry paraemter set to | |
1746 | DIRENT_DELETED_FILE. | |
1747 | ||
1748 | Added new functions, ext2fs_inode_alloc_stats and | |
1749 | ext2fs_block_alloc_stats, which takes updates block/inode allocation | |
1750 | statistics in the bitmaps, block group descriptors, and superblock | |
1751 | when inodes or blocks are allocated or deallocated. | |

1754 | E2fsprogs 1.25 (September 20, 2001) |
1755 | =================================== | |
1756 | ||
1757 | This is primarily a bug-fix release; no new features were added, but | |
1758 | there are a number of embarassing bug fixes and cleanups applied. | |
1759 | ||
1760 | Fix a bug mke2fs which causes stack garbage to be written to disk when | |
1761 | zapping disk sectors. (This bug could cause mke2fs to core dump for | |
1762 | some kernels, I suspect with security enhancement patches.) | |
1763 | ||
1764 | Remove unneeded #include of <linux/config.h> which was breaking | |
1765 | building e2fsprogs on the Hurd. (Addresses Debian bug #112414.) | |
1766 | ||
1767 | Updated tune2fs man page to reflect the fact that adding or removing a | |
1768 | journal doesn't require running e2fsck. | |
1769 | ||
1770 | Remove use of AC_REQUIRE from autoconf which had been used to prevent | |
1771 | AC_CANONICAL_HOST from being called twice; unfortunately this causes | |
1772 | recent autoconf to bomb out since they don't allow AC_REQUIRE to be | |
1773 | used outside of autoconf macros. Fortunately, it doesn't seem to be | |
1774 | necessary any more, anyway. | |
1775 | ||
1776 | E2fsck will now not fall back to an alternate superblock if the user | |
1777 | specifies the superblock location explicitly on the command-line. | |
1778 | This allows easier recovery from a situation where the primary | |
1779 | superblock and block groups are slightly corrupted, but the backup | |
1780 | superblocks are completely broken. | |
1781 | ||
1782 | Fix problem which caused compile_et and mk_cmds to blow up if | |
1783 | e2fsprogs was in a directory with a pathname that contained spaces. | |
1784 | ||
1785 | We are now more paranoid about checking the entry in /etc/mtab to make | |
1786 | sure the filesystem is really mounted, since some broken distributions | |
1787 | (read: Slackware) don't initialize /etc/mtab before checking non-root | |
1788 | filesystems. (Slackware also doesn't check the root filesystem | |
1789 | separately, and reboot if the root filesystem had changes applied to | |
1790 | it, which is dangerous and broken, but there's nothing I can do about | |
1791 | that.) | |
1792 | ||
1793 | Make UUID library C++ friendly by adding appropriate extern "C" | |
1794 | declarations and using const in the function declarations. | |
1795 | ||
1796 | Fix up the com_err texinfo file so that it can product a valid info | |
1797 | file (previously, it could only be used to generate paper | |
1798 | documentation using texinfo.tex). | |
1799 | ||
1800 | ||
fb70775b TT |
1801 | E2fsprogs 1.24a (September 2, 2001) |
1802 | =================================== | |
1803 | ||
1804 | Fix brown-paper bug in mke2fs which caused it to segfault when | |
1805 | printing the version string. | |
1806 | ||
1807 | ||
109624a1 TT |
1808 | E2fsprogs 1.24 (August 30, 2001) |
1809 | ================================ | |
1810 | ||
1811 | Revert the BLKGETSIZE64 support, since for some distributions, this | |
1812 | ioctl has been used by an unofficial kernel patch to update the last | |
1813 | sector on the disk, and this was causing disk corruption problems as a | |
1814 | result. | |
1815 | ||
1816 | Mke2fs is now more careful about zapping swap space signatures and | |
1817 | other filesystem/raid superblock magic values so that programs like | |
1818 | mount who try to use hueristics to determine the filesystem type of a | |
1819 | partition are less likely to be confused. | |
1820 | ||
1821 | E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a | |
1822 | regular file (since Andreas Dilger's on-line resizing tools will set | |
1823 | its mode bits). | |
1824 | ||
1825 | Fixed some minor texinfo, man pages nits for spelling errors, | |
1826 | texinfo warnings, etc. (Addresses Debian bug #110621.) | |
1827 | ||
1828 | E2fsprogs program no longer print the filesystem version number | |
1829 | (i.e. 0.5b), since it only confuses people and doesn't serve any real | |
1830 | purpose. | |
1831 | ||
1832 | E2fsck will once again compile under libc5, since it will supply its | |
1833 | own version of strnlen if necesssary. | |
1834 | ||
1835 | mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers | |
1836 | when specifying the external journal device. tune2fs will also search | |
1837 | devices looking for the externla journal debice when removing. | |
1838 | ||
1839 | E2fsprogs 1.23 (August 15, 2001) | |
1840 | ================================ | |
d1ef5c34 TT |
1841 | |
1842 | Add initial support for extended attributes (EA); e2fsck will | |
6c0a0417 TT |
1843 | correctly handle a filesystem with EA's and check the EA blocks for |
1844 | corruptions. | |
1845 | ||
d494bba8 TT |
1846 | E2fsck's symlink sanity checking has been cleaned up. It now checks |
1847 | the i_size value of fast symlinks, and checks for immutable flags | |
1848 | being set of symlinks, etc. | |
1849 | ||
c4ac9e14 TT |
1850 | E2fsck now offers to clear inodes which are special files that have a |
1851 | non-zero i_blocks or i_size field. (The i_size field check was in the | |
1852 | previous version of the code, but due to a bug it didn't offer to | |
1853 | clear the inode unless i_size and i_size_high were both non-zero.) | |
1854 | ||
d494bba8 TT |
1855 | E2image can now create "raw" image files, which only contain the |
1856 | filesystem metadata placed in a spare file so that e2fsck, dumpe2fs, | |
1857 | debugfs, etc., can be run directly on the raw image file. | |
bf16d106 TT |
1858 | |
1859 | Add support for the 64-bit block device patches. | |
1860 | ||
1861 | Fixed bugs in creating external journals with a 1k blocksize. | |
1862 | ||
d494bba8 TT |
1863 | Add initial support for external journals (so long as the external |
1864 | journal only supports a single filesystem) in e2fsck. | |
1865 | ||
1866 | Remove requirement for needing to run fsck on a filesystem after | |
1867 | removing a journal (either internal or external). | |
1868 | ||
bf16d106 | 1869 | The man pages now document how to create and manage external journals. |
d1ef5c34 TT |
1870 | |
1871 | Speed up the check of an ext3 filesystems by avoiding a needless flush | |
1872 | of all of the superblock and block group descriptors. | |
1873 | ||
d494bba8 TT |
1874 | Speed up creating an internal journal using tune2fs in the case where |
1875 | the filesystem has a lot blocks already allocated. | |
1876 | ||
c4ac9e14 TT |
1877 | Tune2fs has been fixed to make sure that only error messages go to |
1878 | stderr, and normal message go to stdout. (Addresses Debian bug #108555) | |
1879 | ||
d494bba8 | 1880 | Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will |
c4ac9e14 | 1881 | now not set the sparse_super feature. (Addresses Debian bug #108165) |
d494bba8 | 1882 | |
d1ef5c34 TT |
1883 | Add support in fsck for the filesystem type "auto". |
1884 | ||
c4ac9e14 TT |
1885 | Fsck -A will not try to interpret device names for filesystems which |
1886 | have a pass number is 0. (Addresses Debian bug #106696). | |
1887 | ||
1888 | Fsck prints a warning message if now valid filesystems are passed to | |
1889 | it. (Addresses Debian Bug #107458.) | |
1890 | ||
9249d980 TT |
1891 | E2fsck now gives an explicit warning if there filesystem still has |
1892 | errors at the end of the run. (Addresses Debian bug #104502) | |
1893 | ||
d494bba8 | 1894 | E2fsck will set the EXT2_ERROR_FS flag if the journal superblock |
c4ac9e14 TT |
1895 | reflects an error. E2fsck will also not run the orphan list if the |
1896 | filesystem contains errors, since the orphan list might be corrupted. | |
d494bba8 TT |
1897 | |
1898 | E2fsck now prints the number of large files when given the -v option. | |
1899 | ||
1900 | Fixed minor memory leaks in e2fsck. | |
bf16d106 | 1901 | |
c4ac9e14 | 1902 | Some minor man pages updates. (Addresses Debian bug #30833, #108174) |
9249d980 | 1903 | |
d1ef5c34 | 1904 | |
19d6b54b TT |
1905 | E2fsprogs 1.22 (June 22, 2001) |
1906 | ============================== | |
1907 | ||
1908 | Fixed a bug in e2fsck's handling of orphan inodes which are special | |
1909 | files (i.e., block/character device files, named FIFO's, etc.). | |
1910 | ||
1911 | Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused | |
1912 | tune2fs to fail at adding a journal to a mounted filesystem. | |
1913 | ||
1914 | Fixed a few big-endian bugs in e2fsprogs | |
1915 | * The directory block functions were accidentally reporting | |
1916 | some directories as corrupted when they weren't. | |
1917 | * If e2fsprogs is compiled --disable-swapfs, the C language | |
1918 | equivalents weren't being included for big-endian platforms. | |
1919 | (Fixes Debian bug #101686). | |
1920 | ||
1921 | Fixed a Hurd compilation problem. (Addresses Debian bug #101361) | |
1922 | ||
1923 | Programmer's notes: | |
1924 | ------------------- | |
1925 | ||
1926 | Use platform independent method of defining the BLKFLSBUF and FDFLUSH | |
1927 | ioctls, and allow them to be defined for non-i386 platforms. | |
1928 | ||
1929 | The uuid.h header file is now protected against multiple inclusions. | |
1930 | ||
1931 | E2fsprogs is now being developed using BitKeeper. Changed the test | |
1932 | scripts to deal with BK's stripping CR characgters from text files, | |
1933 | and changed the top-level Makefile.in to avoid including BitKeeper | |
1934 | files when generating the source tarball. | |
1935 | ||
1936 | ||
b90b826b TT |
1937 | E2fsprogs 1.21 (June 15, 2001) |
1938 | ============================== | |
1939 | ||
1940 | Added new configure flags which allow a subset e2fsprogs to be built; | |
1941 | this is most useful for boot floopies, since the resulting shared | |
1942 | libraries and programs are slimmed down by removing features that | |
1943 | aren't necessary for a boot floppy. The new flags that were added | |
1944 | are: --disable-swapfs, which removes support for byte swapping old | |
1945 | legacy PPC/68k filesystems, --disable-debugfs, which removes support | |
1946 | for debugfs from the libext2fs library, --disable-imager, which | |
1947 | removes support for the e2image program, and --disable-resizer, which | |
1948 | removes support for resize2fs. | |
1949 | ||
1950 | E2fsck now prints the number of mounts or days elapsed since the last | |
1951 | check when e2fsck is forced to check an otherwise clean filesystem. | |
1952 | ||
1953 | Tune2fs now prints an informative message about how often a filesystem | |
1954 | will be checked when adding a journal to the filesystem, to remind the | |
1955 | user that he/she may want to adjust those parameters using tune2fs | |
1956 | -c/-i. | |
1957 | ||
1958 | Worked around hurd brain-damage which causes e2fsck to sometimes | |
1959 | believe a filesystem is the root filesystem based on device numbers | |
1960 | (since Hurd doesn't have dev_t's, which is arguably a POSIX.1 | |
1961 | violation). | |
1962 | ||
1963 | Fixed a bug introduced in 1.20 which caused e2fsck to abort with an | |
1964 | erroneous error with the -F option was specified. | |
1965 | ||
1966 | Fixed a ext3 recovery bug in the revoke handling; synchronized with | |
c05b5521 TT |
1967 | ext3 0.7a. |
1968 | ||
767de097 TT |
1969 | Fixed two bugs in e2fsck's handling of dup block handling, dealing |
1970 | with relatively uncommon edge cases: a directory with an indirect | |
1971 | block which is claimed by another file, and when the last inode in the | |
1972 | filesystem has blocks claimed by another file. | |
1973 | ||
5a9c036b TT |
1974 | E2fsck now checks to see if the i_size field of a fast symlink is too |
1975 | big, and offers to clear the symlink if so. | |
1976 | ||
1977 | E2fsck now checks to see if i_size_high of special files is non-zero, | |
1978 | and offers to clear i_size_high. | |
1979 | ||
767de097 TT |
1980 | Fix e2fsck's handling of incompatible journal flags so that the user |
1981 | has chance to abort, and then has the option to clear out the journal | |
e333845b | 1982 | entirely. (Addresses Debian bug #98527.) |
767de097 | 1983 | |
b90b826b TT |
1984 | Fixed a bug in fsck which could cause it to core dump if a mix of |
1985 | standard and non-standard device names are used in /etc/fstab. | |
1986 | (Debian bug #100559) | |
1987 | ||
c05b5521 TT |
1988 | Fixed a bug in debugfs which caused read errors when copying a file to |
1989 | not be noticed. | |
1990 | ||
b90b826b TT |
1991 | The debugfs set_super_value command can now modify the s_lastcheck field. |
1992 | ||
c05b5521 TT |
1993 | Fixed a bug in lsattr and chattr which was accidentally introduced in |
1994 | 1.20 to support > 2GB files; both lsattr and chattr wasn't reading | |
1995 | directories correctly because the change modified the layout of struct | |
1996 | dirent to be incompatible with the libe2p shared library. | |
1997 | ||
b90b826b TT |
1998 | Cleaned up the mke2fs manual page and included a discussion about why |
1999 | it's good to periodically check the filesystem even when journaling is | |
2000 | enabled. | |
2001 | ||
767de097 TT |
2002 | Programmer's notes: |
2003 | ------------------- | |
2004 | ||
2005 | Fix general gcc -Wall complaints. | |
2006 | ||
2007 | The types needed by the ext2 header files are now provided by | |
2008 | lib/ext2fs/ext2_types.h, instead of include/asm/types.h. | |
2009 | ||
c05b5521 | 2010 | Integers are now preferred to longs when trying to find a 32-bit type |
b90b826b TT |
2011 | in ext2_types.h. Also, if linux/types.h has already been defined, |
2012 | don't try to redefine the types. | |

767de097 TT |
2014 | Fixed make depend script so that it automatically corrects the |
2015 | pathname cleanups performed by make -M, so I don't have to fix them up | |
2016 | by hand. | |
2017 | ||
2018 | Fixed the d_loaddump test case to be more robust, and not depend on | |
2019 | bash'isms. | |
2020 | ||
2021 | Removed debugfs's dependence on pread(), which was accidentally | |
2022 | intrudced in e2fsprogs 1.20 | |
2023 | ||
c05b5521 TT |
2024 | Fixed a performance bug in the libext2fs's icount routine; the size |
2025 | estimate of the icount array was incorrectly being calculated. | |
2026 | ||
b90b826b TT |
2027 | Removed use of the badblocks compatibility functions in the e2fsprogs |
2028 | programs. | |
2029 | ||
2030 | Added paranoia code which protects against strange cases where /etc | |
2031 | isn't on the root filesystem, or if /etc/mtab doesn't exist. | |
2032 | ||
2033 | The header file ext2_types.h is now installed. | |
2034 | ||
2035 | Autoconf is used to determine when we are on big-endian machines, | |
2036 | instead of doing run-time tests, to save a few bytes of code. | |
2037 | ||
2038 | The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap | |
2039 | functions are no longer inline functions, which saves space and | |
2040 | doesn't really cost any real performance. | |
2041 | ||
2042 | The ext2fs library no longer depends on the e2p library. (What need | |
2043 | there was of it --- namely, fsetflags, was coded in-line). | |
2044 | ||
2045 | Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even | |
2046 | when the user is stupid and tries compiling the package using "make | |
2047 | install" as root. | |
2048 | ||
2049 | Miscellaneous code cleanups: | |
2050 | * Added missing files from Makefile.in's SRCS file, so that | |
2051 | their dependencies would be properly calculated. | |
2052 | * Removed redundant code | |
2053 | * Fixed comments in code | |
2054 | * Removed no-longer unneeded argsused #pragma. | |

5a009bb9 | 2057 | E2fsprogs 1.20 (May 20, 2001) |
31d1d0c8 | 2058 | ============================= |
5570a65a | 2059 | |
31d1d0c8 TT |
2060 | Add support for replaying the ext3 journal purely in user mode, |
2061 | including handling the orphaned inode list. Used code contributed by | |
2062 | Andreas Dilger, with bug fixes and the orphaned inode handling done | |
2063 | by Theodore Ts'o. | |
2064 | ||
2065 | The mke2fs and tune2fs programs can create or modify a filesystem to | |
2066 | include an ext3 journal. Tune2fs also can be used to remove an ext3 | |
2067 | journal from a filesystem. | |
5570a65a TT |
2068 | |
2069 | E2fsck will now check for the existence of a linked list of orphan | |
2070 | inodes in the superblock, and clear those inodes before starting the | |
2071 | rest of the filesystem check (but after the journal playback). | |
2072 | ||
31d1d0c8 TT |
2073 | E2fsck now validates the file descriptor passed to the -C option, |
2074 | which saves against the completion bar getting written to an | |
2075 | unexpected location, such as the disk being checked. (Debian | |
2076 | bug/wishlist #55220) | |
2077 | ||
2078 | E2fsck will now bump the filesystem revision number from zero to one | |
2079 | if any of the compatibility bits are set. | |
2080 | ||
2081 | Fixed a bug where a badly corrupted directory on a big endian system | |
2082 | could cause e2fsck to die with a bus error. The | |
2083 | ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in | |
2084 | the ext2 library now does alignment sanity checks on the rec_len field | |
2085 | of the directory entry before using it. | |
2086 | ||
2087 | The ext2 library has been enhanced to make tune2fs safe to run on | |
2088 | mounted filesystems. (Users could usually get away with using tune2fs | |
2089 | on mounted filesystems before, but with the advent of ext3 and | |
2090 | journaling, it became important to make tune2fs was *really* safe for | |
2091 | use even when the filesystem being modified is mounted.) E2label is | |
2092 | now implemented by tune2fs using an argv[0] dispatch, so that e2label | |
2093 | is also now safe for use on mounted filesystems. | |
2094 | ||
2095 | Added a new program, e2image, which creates a backup of critical ext2 | |
2096 | filesystem data structures. The generated image file can be examined | |
2097 | using dumpe2fs and debugfs. In the future, e2fsck will be able to use | |
2098 | the image file to help recover very badly damaged filesystems. | |
2099 | ||
2100 | Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files | |
2101 | no longer cause e2fsck to bomb out. Also treat files > 2GB as being | |
2102 | large file when deciding whether or not the filesystem has large files. | |
2103 | ||
2104 | Fixed lsattr and chattr so that they work correctly on large files. | |
2105 | (Fixes Debian bug #72690.) | |
2106 | ||
2107 | Removed limitation in get_device_size() which imposed a one terrabyte | |
2108 | filesystem limitation. (Most 2.2 kernels still have a signed int | |
2109 | problem which cause 1 TB block device limitation. Fortunately, the | |
2110 | kernel patches to fix this are much easier than fixing the 2TB | |
2111 | limitation in the kernel. :-) | |
2112 | ||
2113 | A max_mount_count of zero is now treated as if no mount count were | |
2114 | set. (Previously, no mount count was indicated by using -1, and a | |
2115 | mount count of zero caused e2fsck to always be run.) | |
2116 | ||
77648565 | 2117 | Mke2fs supports two new filesystem types largefile and largefile4. |
31d1d0c8 TT |
2118 | |
2119 | Mke2fs now adds some randomness in s_max_mount_count so that multiple | |
2120 | filesystems won't be all checked at the same time under normal | |
2121 | operations. | |
2122 | ||
5570a65a TT |
2123 | Fixed bug in the progress bar printing code which could cause e2fsck |
2124 | to core dump on an illegal filesystem. | |
2125 | ||
31d1d0c8 TT |
2126 | Fixed bug in fsck which could allow more than one instance of e2fsck |
2127 | to be printing a progress bar. (Debian bug #65267) | |
2128 | ||
5570a65a TT |
2129 | Fsck using a UUID or a LABEL specifier will work even if devfs is |
2130 | compiled into the kernel and not mounted. If the pathnames in | |
2131 | /proc/partitions are incorrect, fsck will search /dev for the correct | |
2132 | device (using the new ext2fs_find_block_device library function). | |
2133 | Fsck now also checks the RAID devices first so that they are properly | |
31d1d0c8 TT |
2134 | found when they are in use. Support has also been added to support |
2135 | additional IDE disks and the DAC 960 device names. (Debian bug #94159) | |
2136 | ||
2137 | Fixed a bug in fsck which caused it not deal properly with 16 | |
2138 | byte long filesystem labels. | |
5570a65a | 2139 | |
5a009bb9 TT |
2140 | Fsck's -t option has been made a lot more flexible. The semantics for |
2141 | what happens if a comma-separated list to fsck has been regularized, | |
2142 | and it is now possible to filter what filesystems will get checked | |
2143 | based what is in the filesystem's fstab entry's option field. (Debian | |
2144 | bug #89483.) | |
2145 | ||
5570a65a TT |
2146 | The dumpe2fs program can now print out the group description |
2147 | information in hex, and also prints the location of the superblock and | |
2148 | block group descriptor for those block groups that have them. | |
2149 | ||
2150 | Mke2fs now clears the ext2 superblock before it starts creating a | |
2151 | filesystem, so that the superblock magic number is only written if the | |
2152 | filesystem creation process successfully completes. | |
2153 | ||
2154 | The debugfs program's stat command now pretty-prints the blocks used | |
2155 | by an inode so that it's more compact and informative. | |
2156 | ||
2157 | The debugfs stats command now uses the same libe2p code (which is used | |
2158 | by dumpe2fs) to print the superblock header information. This is more | |
2159 | complete, and it avoids a bit of code duplication. | |
2160 | ||
2161 | Added a new debugfs command, set_super_value (ssv) which allows the | |
2162 | user to set arbitrary superblock fields. | |
2163 | ||
31d1d0c8 TT |
2164 | Debugfs was extended to support inode numbers in hex (by prefixing |
2165 | them with 0x), and so that modify_inode can set the inode generation | |
2166 | number. Also, there is now a new function command called logdump | |
2167 | which will dump an ext3 journal. | |
2168 | ||
2169 | Fixed a bug in debugfs so that quitting out of the pager doesn't kill | |
2170 | debugfs. | |
2171 | ||
2172 | Debugfs's dump command now stops immediately upon reporting a disk | |
2173 | read error. (Fixed a bug in ext2fs_file_read library routine which | |
2174 | caused debugfs not to stop.) (Debian bug #79163) | |
2175 | ||
2176 | On systems with /proc/mounts (mainly Linux systems), /proc/mounts is | |
2177 | checked before /etc/mtab is used, since /proc/mounts is more likely to | |
2178 | be accurate. | |
2179 | ||
2180 | Added portability fixes for Solaris and Linux/ia64. | |
2181 | ||
2182 | Various manual pages were clarified and cleaned up. (Fixed debian | |
2183 | bugs #63442, #67446, and #87216) | |
2184 | ||
5570a65a TT |
2185 | |
2186 | Programmer's notes: | |
2187 | ------------------- | |
2188 | ||
2189 | The e2fsck message printer now supports %Iu and %Ig, which will print | |
2190 | out the inode's user and group owners, respectively. | |
2191 | ||
31d1d0c8 TT |
2192 | E2fsprogs now includes its own version of include/linux/ext2_fs.h, so |
2193 | that no longer dependent on the system having the correct version of | |
2194 | the kernel header files. | |
2195 | ||
5570a65a TT |
2196 | Added a new function to libext2, ext2fs_find_block_device(), which |
2197 | searches the system (i.e., /dev, /devfs, /devices) for a pathname to a | |
2198 | device given its device number. | |
2199 | ||
31d1d0c8 TT |
2200 | Added a new function to libext2, ext2fs_sync_device, which centralizes |
2201 | all of the places which might try to use the BLKFLSBUF or FDFLUSH | |
2202 | ioctls (and usually failing to define them since the system header | |
2203 | files don't usually do this for us, and we're trying to avoid usage of | |
2204 | kernel include files now). | |
2205 | ||
5570a65a TT |
2206 | Added new utility programs in tests/progs: random_exercise and |
2207 | hold_inode. They aren't built by default; they're useful for | |
2208 | exercising ext3 filesystem code. | |
2209 | ||
31d1d0c8 TT |
2210 | Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes |
2211 | the filesystem close functions to only update the superblock, and to | |
2212 | not touch the block group descriptors. Needed by tune2fs when | |
2213 | modifying a mounted filesystem. | |
2214 | ||
2215 | Got rid of struct ext2fs_sb and replaced it with the standard struct | |
2216 | ext2_super_block from include/linux/ext2_fs.h. Note: this may break | |
2217 | source (but not binary) compatibility of some users of the ext2 | |
2218 | library. Those applications should just simply do a global search and | |
7d614e3d TT |
2219 | replace of struct ext2fs_sb with struct ext2_super_block, and include |
2220 | the new header file <ext2fs/ext2_fs.h> which defines it. | |
31d1d0c8 TT |
2221 | |
2222 | The ino_t type has been renamed ext2_ino_t to protect applications | |
2223 | that attempt to compile -D_FILE_OFFSET_BITS=64, since this | |
2224 | inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an | |
2225 | unexpected ABI change. | |
2226 | ||
2227 | The Makefiles have been reworked so that "make check" can be run from | |
2228 | the top-level Makefile. | |
2229 | ||
2230 | Fix general gcc -Wall complaints and removed dead code. | |
2231 | ||
2232 | Remove use of NOARGS, because we assume everyone does ANSI C these | |
2233 | days. | |
2234 | ||
2235 | Added build-rpm script from sct. | |
2236 | ||
2237 | New functions ext2fs_image_{inode,super,bitmap}_{read,write} added | |
2238 | to support e2image. | |
2239 | ||
2240 | New function ext2fs_flush_icache which must be called if the | |
2241 | application program modifies the inode table blocks without going | |
2242 | through ext2fs_write_inode() interface. | |
2243 | ||
2244 | New ext2fs_check_mount_point() function, which will return the mount | |
2245 | point of a device if mounted. | |
2246 | ||
2247 | The io_channel abstraction now has an optional interface, | |
2248 | io_channel_write_range, which allows specific byte ranges to be | |
2249 | written. | |
2250 | ||
2251 | The unix_io IO channel now supports write-through caching, so that | |
2252 | journal creation is more efficient. | |
2253 | ||
2254 | Added x86 assembly language routines to support byte swapping, to | |
2255 | reduce executable size. | |
2256 | ||
2257 | Fixed bug in the utility program subst so that it's possible to | |
2258 | replace a substitution variable with a zero-length string. | |
2259 | ||
2260 | Fixed numbering e2fsck pass1 problem numbers; an extra zero had | |
2261 | slipped into some of the problem number. | |
5570a65a | 2262 | |
b777e26e TT |
2263 | E2fsprogs 1.19 (July 13, 2000) |
2264 | ============================== | |
ab146766 TT |
2265 | |
2266 | Release the resize2fs program since the timeout before it could | |
006ea71e | 2267 | be released under the GPL has finally expired. |
ab146766 TT |
2268 | |
2269 | Add experimental support needed for the ext2 compression patches. | |
2270 | This requires compiling e2fsprogs with the --enable-compression flag | |
2271 | to the configure script. | |
2272 | ||
2273 | Added ext3 journalling support. E2fsck will run the journal (if | |
2274 | necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is | |
2275 | installed as a symlink to e2fsck. Fsck has been taught about ext3, | |
2276 | and treats it the same as ext2 in terms of the progress bar logic. | |
2277 | Dumpe2fs will display the superblock journaling information if the | |
2278 | filesystem has a journal. The ext2 library will now permit opening an | |
2279 | ext3 filesystem with the recovery flag set. This is necessary for | |
2280 | on-line dump's to work correctly, but there may be issues with this | |
2281 | working well since ext3 is much less agressive about syncing blocks to | |
2282 | the filesystem, since they're safe on the journal. | |
2283 | ||
2284 | Tune2fs and e2fsck have been changed to allow the mount_count check to | |
2285 | be disabled by setting max_mount_count to -1. (This was already | |
2286 | supported by the kernel.) | |
2287 | ||
2288 | Create a symbolic link for fsck.ext3, since the e2fsprogs utilities | |
2289 | are used for ext3 as well. | |
2290 | ||
2291 | Added internationalization support for e2fsprogs; must be enabled | |
2292 | by passing --enable-nls to configure. | |
2293 | ||
2294 | Always use the provided ext2fs header files to insulate ourselves from | |
2295 | kernel version changes. Which include files are used by e2fsprogs | |
2296 | have also been cleaned up to improve portability. | |
2297 | ||
2298 | Limit the number of times that e2fsck updates the progress bar so that | |
2299 | people who are booting using a 9600 baud console don't get swampped by | |
2300 | too many updates. | |
2301 | ||
2302 | Improved the loop detection algorithm in e2sck's pass #3 so that it is | |
2303 | much, much faster for large filesystems with a large number of | |
2304 | directories. | |
2305 | ||
2306 | The memory footprint for e2fsck is now slightly smaller than before. | |
2307 | ||
2308 | E2fsck now checks if special devices have a non-zero size, and offers | |
2309 | to clear the size field if it finds such an inode. | |
2310 | ||
2311 | E2fsck now checks if special devices have the append-only flag set, | |
2312 | and offers to clear the inode. | |
2313 | ||
2314 | E2fsck now properly handles some "should never fail" cases during a | |
2315 | bitmap copy in pass5. | |
2316 | ||
2317 | E2fsck now properly prints control characters in filenames as ^A .. ^Z. | |
2318 | ||
31d1d0c8 TT |
2319 | E2fsck now calculates the correct location of the backup superblock in |
2320 | the case of filesystem blocksizes > 1k. | |
2321 | ||
2322 | Fixed a bug in e2fsck's calculation of the number of inodes_per_block | |
2323 | which normally didn't cause problems under most filesystem parameters, | |
2324 | but could cause a valid superblock to be rejected in extreme cases. | |
2325 | Other checks for validating superblock values were made more | |
2326 | stringent. | |
2327 | ||
ab146766 TT |
2328 | Added non-destructive write testing to the badblocks program, courtesy |
2329 | of David Beattie. The badblocks also now has an option to input the | |
2330 | current set of bad blocks, so that known bad blocks are skipped to | |
2331 | speed up the badblocks test. There is also a persistent rescan | |
006ea71e TT |
2332 | feature which causes badblocks to run until it has completed some |
2333 | number of passes without discovering any new bad blocks. | |
ab146766 TT |
2334 | |
2335 | Badblocks now checks to see if the device is mounted and refuses to do | |
2336 | the tests involving writing to the device if it is mounted. Also, | |
2337 | badblocks now allows the number of blocks to be checked to be | |
2338 | defaulted to the size of the partition. | |
2339 | ||
2340 | Fixed a bug in fsck which didn't allow non-root users to be able to | |
2341 | check filesystems if there were any LABEL= or UUID= entries in | |
2342 | /etc/fstab. | |
2343 | ||
2344 | The Hurd doesn't support the filetype filesystem feature. The mke2fs | |
2345 | program now makes sure that for the Hurd, the filestype feature is | |
2346 | turned off. E2fsck will check to see if the filetype feature is | |
2347 | turned on for Hurd filesystems, and offer to turn off the feature. | |
2348 | ||
2349 | Mke2fs now has a safety check to make sure the number of blocks do not | |
2350 | exceed 32 bits even on a 64 bit platform. | |
2351 | ||
2352 | Really fixed a bug in fsck to allow "fsck -As" to run interactive | |
2353 | fsck's. (For those people who like to do interactive fsck's in the | |
2354 | /etc/rc scripts!?!) | |
2355 | ||
2356 | Debugfs has a few new features: the rdump command, which will do a | |
2357 | recursive dump of a directory and all of its contents, and the lcd | |
2358 | command which does a local chdir (much like the ftp command of the | |
2359 | same name). In addition, the debugfs program and the open_filesystem | |
2360 | command now takes three new options: -b and -s, which allows the | |
2361 | blocksize and superblock location to be specified, and the -c option | |
2362 | which is used in catastrophic situations where the block group | |
2363 | descriptors are corrupt. If the -c option is specified, debugfs will | |
2364 | skip trying to read in the block and inode bitmaps. | |
2365 | ||
2366 | Debufs's lsdel command was fixed to handle bad blocks in the inode | |
2367 | table. | |
2368 | ||
2369 | A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use | |
2370 | 4 digit years. | |
2371 | ||
2372 | General improvements in error messages | |
2373 | ||
2374 | - Mke2fs prints a sane error message if the partition size is zero | |
2375 | (usually because the partition table wasn't reread by the | |
2376 | kernel due to the partition being busy), instead of "invalid | |
2377 | argument passed to ext2 library while initializing superblock". | |
2378 | ||
2379 | - Fsck now prints more self-explanatory message if an invalid UUID= | |
2380 | or LABEL= specification is passed to it. | |
2381 | ||
2382 | UUID library changed to use the LGPL. | |
2383 | ||
2384 | Fixed a bug in the UUID library where very rapid calls to the | |
2385 | time-based UUID generator could cause duplicate UUID's to be returned. | |
2386 | This was not a problem for e2fsprogs, but it could be a problem for | |
2387 | other users of the library. | |
2388 | ||
2389 | Make the UUID library more robust in the face of missing or an | |
2390 | improper /dev/urandom or /dev/random files. | |
2391 | ||
2392 | Added some random portability fixes for Solaris. | |
2393 | ||
2394 | Some minor man page updates. | |
2395 | ||
2396 | Fixed a memory leak in the ss library. | |
2397 | ||
2398 | ||
2399 | Programmer's notes: | |
2400 | ------------------- | |
2401 | ||
2402 | We now try to use lseek64 and open64 from the LFS if possible. | |
2403 | ||
2404 | The 3rd parameter in e2p's print_flags is now a flags word, instead of | |
2405 | a boolean option. | |
2406 | ||
2407 | The mark and unmark bitmap functions now return the previous state of | |
2408 | the bit that was being changed, which is useful for some speed | |
2409 | optimizations. | |
2410 | ||
2411 | The following functions have been added to enhance the badblocks list | |
2412 | handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and | |
2413 | ext2fs_badblocks_equal. | |
2414 | ||
2415 | The ext2 header files now have the latest journalling fields to the | |
2416 | superblock. | |
2417 | ||
2418 | The ext2fs_mkdir function in libext2fs now properly backs out of error | |
2419 | conditions robustly. | |
2420 | ||
2421 | Cleaned up makefiles: | |
2422 | - to cleanly compile with the -j flag. | |
2423 | - so distclean removes all generated files. | |
2424 | - so in case of an error while installing header files, the make aborts. | |
2425 | ||
2426 | Fix test_script so that it works correctly when compiling in the | |
2427 | source directory. | |
2428 | ||
31d1d0c8 TT |
2429 | The random UUID generation routine has been made slightly better in |
2430 | the case where /dev/random doesn't exist. (Use of randomly-based UUID | |
2431 | is still not recommended if /dev/random doesn't exist, however; it's | |
2432 | better to use the time/ethernet MAC address UUID in this case.) | |
ab146766 TT |
2433 | |
2434 | Clean up the build process so it's more friendly in case of missing | |
2435 | directories. | |
2436 | ||
2437 | The ext2fs header file can now be #include'd into C++ programs. | |
2438 | ||
2439 | The e2p.h header file is now installed. | |
2440 | ||
2441 | Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds. | |
2442 | ||

2445 | E2fsprogs 1.18 (November 10, 1999) |
2446 | ================================== | |
2447 | ||
2448 | Fix a core dumping bug in e2fsck if an imagic inode is present or | |
2449 | (more rarely) if the filesystem is badly corrupted enough that e2fsck | |
2450 | has to restart pass 1 processing. E2fsck now closes the filesystem | |
2451 | before freeing a large number of its data structures, so in the case | |
2452 | of future memory faults, at least the fixed filesystem will be fully | |
2453 | written out. | |
2454 | ||
2455 | If a filesystem doesn't support imagic inodes, and e2fsck discovers an | |
2456 | imagic inode, it will offer to clear the imagic flag. | |
2457 | ||
2458 | E2fsck will now offer to clear the immutable flag on special files | |
2459 | (device/socket/fifos) when running it in non-preen mode. | |
2460 | ||
2461 | E2fsck will now set the filetype when creating /lost+found, and when | |
2462 | connected orphaned inodes to /lost+found. | |
2463 | ||
2464 | Debugfs's ncheck and icheck commands now handles the case where there | |
2465 | are bad blocks in the inode table without bombing out. | |
2466 | ||
2467 | The badblocks list processing code has been made more efficiently for | |
2468 | appending a large number of (ordered) badblocks to the badblocks list. | |
2469 | ||
2470 | Some minor man page updates. | |
2471 | ||
2472 | Fsck now allows interactive e2fsck's when using fsck -As (not a common | |
2473 | mode, but some people like to do this in boot scripts for silly reasons). | |
2474 | ||
2475 | Programmer's notes: | |
2476 | ------------------- | |
2477 | ||
2478 | The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet | |
2479 | with the problem code convention. | |
2480 | ||
2481 | The badblocks list regression test program has been updated to work | |
2482 | with previously made API name changes. | |
2483 | ||
2484 | The ext2fs_free() command now uses the new badblocks API to avoid | |
2485 | using the compatibility layer. | |
2486 | ||
2487 | Added new regression test cases; the run_e2fsck test script now | |
2488 | supports the ability for a test case to run a prepratory command | |
2489 | before running e2fsck. | |
2490 | ||
28e1194e TT |
2491 | E2fsprogs 1.17 (October 26, 1999) |
2492 | ================================= | |
2493 | ||
2494 | Fixed nasty typo in fsck which caused parallelized fsck's to go into an | |
2495 | infinite loop. | |
2496 | ||
2497 | Fixed a bug in fsck where it used strncmp to compare a binary UUID, | |
2498 | thus potentially causing problems if a binary UUID contained a NULL | |
2499 | character. | |
2500 | ||
2501 | E2fsck now uses stricter checks for directory entries in pass 2: | |
2502 | zero-length filenames are not allowed; neither are 8 byte long | |
2503 | directory entries. | |
2504 | ||
2505 | The debugfs "dirty" command now clears the filesystem valid bit. | |
2506 | (Previously this just set the dirty-as-in-needs-writing-out-to-disk | |
2507 | bit in the in-core superblock image. The new functionality is more | |
2508 | what the user expects, and is more useful.) | |
2509 | ||
2510 | Added a debugging hook to test parallel fsck; if the environment | |
2511 | variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive | |
2512 | will be checked in parallel when they normally would not be. | |
2513 | ||
2514 | Programmer's notes: | |
2515 | ------------------- | |
2516 | ||
2517 | Fixed some #ifdef's for compilation under the Hurd OS. | |
2518 | ||
2519 | Fixed minor W2K compatibility problems. | |
2520 | ||
2521 | Fixed some miscellaneous GCC warnings. | |
2522 | ||
2523 | ||
8a31ffef TT |
2524 | E2fsprogs 1.16 (October 22, 1999) |
2525 | ================================= | |
2526 | ||
2527 | Fixed a race condition bug in fsck; when printing a progress bar, if | |
2528 | checking multiple filesystems in parallel, it was possible for fsck to | |
2529 | send e2fsck a SIGUSR1 signal before e2fsck had installed its signal | |
2530 | handler, which would cause it to terminate with a signal 10. | |
2531 | ||
2532 | E2fsck now properly handles filesystems that have the | |
2533 | INCOMPAT_FILETYPE feature turned on. It can be used to convert a | |
2534 | filesystem into using or not using FILETYPE feature. | |
2535 | ||
2536 | E2fsck now properly handles filesystems that have the IMAGIC feature | |
2537 | turned on (this is used on Linux AFS servers). | |
2538 | ||
2539 | The mke2fs program now creates filesystems that have the filetype and | |
2540 | sparse_superblock features enabled by default, unless it is run on a | |
2541 | pre-2.2 kernel. These features are not supported by a pre-2.2 kernel, | |
2542 | so there is now a new flag -O which allows the user to specify with | |
2543 | which features she would like to create the filesystem; "mke2fs -O | |
2544 | none" will create a filesystsem compatible with 2.0 kernels. | |
2545 | ||
2546 | The tune2fs program now has a -O option which allows the user to set | |
2547 | and reset "safe" filesystem features. Currently, the only ones which | |
2548 | allows to be modified are the filetype and sparse_superblock features. | |
2549 | Note setting or clearing either feature will require running e2fsck on | |
2550 | the filesystem afterwards. (n.b. Clearing the sparse_superblock feature | |
2551 | requires that there is enough free space on the filesystem for the | |
2552 | extra superblocks which will be created by e2fsck.) | |
2553 | ||
2554 | Debugfs can now set and print filesystem features in the superblock | |
2555 | using the "features" command. Dumpe2fs will print out the complete | |
2556 | set of features when listing the superblock. | |
2557 | ||
2558 | Dumpe2fs has new options -f (force) and -h (header-only). | |
2559 | ||
2560 | Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead | |
2561 | message to come up. This could happen when decrementing or | |
2562 | incrementing a link count could result in an overflow. | |
2563 | ||
2564 | Fixed a bug in e2fsck where the block count on the lost+found | |
2565 | directory would not be properly incremented when the directory was | |
2566 | expanded to the point where an indirect block needed to be allocated. | |
2567 | ||
2568 | E2fsck now makes some additional sanity checks on the superblock to | |
2569 | avoid crashing or giving a memory allocation error if some of the | |
2570 | values in the superblock are unresonable (but the superblock otherwise | |
2571 | looks valid). | |
2572 | ||
2573 | Fixed a bug in e2fsck where a very badly corrupted filesystem might | |
2574 | require two passes to completely fix the filesystem. This happened if | |
2575 | an inode claimed blocks that was part of the filesystem metadata | |
2576 | (typically, when garbage was written into an inode table or indirect | |
2577 | block, since this kind of filesystem corruption normally doesn't | |
2578 | happen otherwise). | |
2579 | ||
2580 | On the Alpha, glibc declares st_flags although it isn't actually used; | |
2581 | the configure script was improved to detect this case so that | |
2582 | e2fsprogs can avoid using the non-functional stat field. | |
2583 | ||
2584 | The manual pages were updated to use a more consistent formatting | |
2585 | style consistent with standard Unix man pages. Mke2fs's man page | |
2586 | added documentation for a few previously undocumented options. | |
2587 | ||
2588 | Fixed minor display bugs in tune2fs and mke2fs. | |
2589 | ||
2590 | Programmer's notes: | |
2591 | ------------------- | |
2592 | ||
2593 | Improved portability of e2fsprogs to non-Unix systems (in particular, NT). | |
2594 | ||
2595 | Added features to parse and print feature strings into the e2p library. | |
2596 | (e2p_feature2string, e2p_string2feature, e2p_edit_feature). | |
2597 | ||
2598 | ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories | |
2599 | whose directory entries contain proper filetype information if the | |
2600 | filesystem supports it. | |
2601 | ||
2602 | ext2fs_link() now uses the low 3 bits of its flags parameter to pass | |
2603 | the directory entry filetype information. This is used to set the | |
2604 | directory entry filetype information if the filesystem supports it. | |
2605 | ||
2606 | Fixed a bug in ext2fs_expand_dir() where the block count in a | |
2607 | directory's inode would not be properly incremented when the directory | |
2608 | was expanded to the point where an indirect block needed to be | |
2609 | allocated. | |
2610 | ||
2611 | ||
a39f3efe | 2612 | E2fsprogs 1.15 (July 18, 1999) |
e2a99be6 | 2613 | ============================== |
6d53db3f TT |
2614 | |
2615 | Add configuration checks so that e2fsprogs will compile cleanly on | |
2616 | Linux 2.3 kernels that have renamed i_version to i_generation. | |
2617 | ||
e2a99be6 TT |
2618 | E2fsck now prints a progress/completion bar (and not just a simple |
2619 | spinner) if the -C0 option is requested or if it receives a SIGUSR1 | |
2620 | signal. Fsck will automatically manage the (potentially muliple) | |
2621 | e2fsck processes to print completion bars if it is given a -C option, | |
2622 | with the right thing happening if multiple filesystems are being | |
2623 | checked in parallel. | |
2624 | ||
2625 | Mke2fs now has better automatic hueristics to determine the filesystem | |
2626 | parameters to be used for a particular filesystem. Added a new option | |
2627 | -T which allows the user to specify how the filesystem is to be used, | |
2628 | which helps mke2fs do a better job selecting the filesystem parameters. | |
2629 | ||
a39f3efe TT |
2630 | Mke2fs now creates revision 1 filesystems by default, and with the |
2631 | sparse superblock feature enabled. The sparse superblock feature is | |
8a31ffef TT |
2632 | not understood by Linux 2.0 kernels, so they will only allow read-only |
2633 | mounts of filesystems with this sparse superblocks. | |
a39f3efe | 2634 | |
6d53db3f TT |
2635 | Fix bug where if /dev/null couldn't be opened (should never happen), |
2636 | e2fsck would hang in a tight loop. | |
2637 | ||
2638 | Make e2fsck handle the case where /lost+found isn't a directory. | |
2639 | ||
2640 | E2fsck now uses mallinfo if it exists to get accurate statistics about | |
2641 | its memory usage. | |
2642 | ||
2643 | Fix bug in e2fsck where it wouldn't check to see if a disconnected | |
2644 | inode had any problems before connecting it to /lost+found. | |
2645 | ||
2646 | Add check to e2fsck so it makes sure that total number of inodes in | |
2647 | the filesystem is a sane number. | |
2648 | ||
2649 | Fix fencepost error when clearing an the end of the block bitmap which | |
2650 | caused the last block in the bitmap not to get cleared. | |
2651 | ||
2652 | Cleaned up a number of messages in e2fsck: | |
2653 | * The message "Group's #'s copy of the group descriptor..." | |
2654 | was fixed so that the correct number would be displayed. | |
2655 | * Added missing space in the "disk write-protected" error messsage | |
2656 | * Cleaned up the error message printed when a non-interactive | |
2657 | e2fsck needs to abort a check because the filesystem | |
2658 | appears to be mounted. | |
2659 | ||
2660 | Added a new command-line utility, uuidgen, which will create and print | |
2661 | a UUID. | |
2662 | ||
2663 | Make debugfs's icheck command more robust by checking to make sure an | |
2664 | inode has valid blocks before interarting over the inode's blocks. | |
2665 | ||
2666 | UUID generation now uses a random-based scheme whenever possible to | |
2667 | prevent potential privacy problems. | |
2668 | ||
2669 | Man pages for all of the UUID functions in the lirbary were added. | |
2670 | ||
2671 | Fixed bug in fsck so it won't coredump if a filesystem not in | |
2672 | /etc/fstab is given to it. | |
2673 | ||
2674 | Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab | |
2675 | that most of the other mount utilities understands. | |
2676 | ||
2677 | Mke2fs will make a filesystem even if it appears mounted if the force | |
2678 | option is given. | |
2679 | ||
2680 | Dumpe2fs has new command-line options which allow a filesystem expert | |
2681 | to specify the superblock and blocksize when opening a filesystem. | |
2682 | This is mainly useful when examining the remains of a toasted | |
2683 | filesystem. | |
2684 | ||
2685 | The badblocks program has been updated to display correctly on disks | |
2686 | with large block numbers. | |
2687 | ||
e2a99be6 TT |
2688 | The badblocks program no longer gives spurious errors when errors |
2689 | occur on non-block boundaries, which is common if the blocksize is | |
2690 | larger than 1k. | |
2691 | ||
6d53db3f TT |
2692 | Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the |
2693 | MKE2FS_SYNC environment variable is set. This is to work around a VM | |
2694 | bug in the 2.0 kernel. I've heard a report that a RAID user was able | |
a39f3efe TT |
2695 | to trigger it even using a 2.2 kernel, but hopefully it will not be |
2696 | needed for most Linux 2.2 users. | |
6d53db3f TT |
2697 | |
2698 | Fixed miscellaneous documentation and man pages. | |
2699 | ||
2700 | Programmer's notes: | |
2701 | ------------------- | |
2702 | ||
2703 | Cleaned up functions such as pass1_get_blocks, pass1_read_inode which | |
2704 | in e2fsck's pass1.c really should have been static. | |
2705 | ||
2706 | The return value of the uuid_compare() function was changed to make it | |
2707 | match with the convetions used by strcmp, memcmp, and Paul Leach's | |
2708 | UUID sample document. | |
2709 | ||
2710 | The "make depend" process has now been made more automated; it now | |
2711 | automatically word-wraps the dependencies, and only replaces source | |
2712 | Makefile.in if there has been a change in the dependencies. Also, a | |
2713 | top-level "make depend" now recurses through all the subdirectories | |
2714 | automatically. | |
2715 | ||
2716 | The Makefile in .../util has been changed so that subst is built using | |
2717 | the native C compiler during a cross-compilation, since the subst | |
2718 | program is only used during the build process. Also add an explicit | |
2719 | rule to build util/subst by cd'ing to the correct directory and | |
2720 | running Makefile. | |
2721 | ||
2722 | The man directories are defined in terms mandir, so that the configure | |
2723 | script can override the location of the manual pages. | |
2724 | ||
2725 | The config files have been updated to recognize new machine types for | |
2726 | both the i386 and alpha families. | |
2727 | ||
2728 | Fsck has been modified so that it will accurately create an | |
2729 | fsck_instance even when the noexecute flag is set. This allows for | |
2730 | accurate debugging of the fsck pass structure. Also, when the verbose | |
2731 | flag is given twice, fsck will print debugging information about when | |
2732 | fsck is waiting for jobs to finish. | |
2733 | ||
2734 | ||
14790ed7 TT |
2735 | E2fsprogs 1.14 (January 9, 1999) |
2736 | ================================ | |
2737 | ||
2738 | Fix the fstab parsing code so that it can handle blank lines and | |
2739 | comment characters. Also, missing pass numbers need to be treated as | |
2740 | zero. | |
2741 | ||
2742 | Fixed a bug in e2fsck where under some circumstances (when e2fsck | |
2743 | needs to restart processing after fixing an egregious inconsistency) | |
2744 | it would try to access already freed memory. | |
2745 | ||
2746 | E2fsck now prints non-printable characters in directory entries and | |
2747 | pathnames using '^' and 'M-' notation. | |
2748 | ||
2749 | Fixed chattr so that it will ignore symbolic links when doing | |
2750 | recursive descent traversals. For both chattr and lsattr, no longer | |
2751 | print the version string unless the -V option is given. | |
2752 | ||
2753 | Allow the system administrator to directly specify the number of | |
2754 | inodes desired in the filesystem, for some special cases where this is | |
2755 | necessary. | |
2756 | ||
2757 | Fix portability problems so that e2fsprogs can be compiled under Linux | |
2758 | 1.2 systems and Solaris systems. | |
2759 | ||
2760 | Update the config.guess file with a more recent version that will | |
2761 | identify newer Linux platforms. | |
2762 | ||
2763 | Programmer's notes | |
2764 | ------------------ | |
2765 | ||
2766 | Ext2fs_read_inode and ext2fs_write_inode will now return an error if | |
2767 | an inode number of zero is passed to them. | |
2768 | ||
556ad132 TT |
2769 | E2fsprogs 1.13 (December 15, 1998) |
2770 | ================================== | |
2771 | ||
2772 | Fixed a bug in debugfs where an error messages weren't getting printed | |
2773 | when the ext2 library routines to read inodes returned errors in the | |
2774 | stat, cmri and rm commands. | |
2775 | ||
2776 | Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is | |
2777 | provided, it won't create an inode table smaller than the minimum | |
2778 | number of inodes required for a proper ext2 filesystem. | |
2779 | ||
2780 | Fsck now parses the /etc/fstab file directly (instead of using | |
2781 | getmntent()), so that it can distinguish between a missing pass number | |
2782 | field and pass number field of zero. This caused problems for | |
2783 | diskless workstations where all of the filesystems in /etc/fstab have | |
2784 | an explicit pass number of zero, and fsck could not distinguish this | |
2785 | from a /etc/fstab file with missing pass numbers. | |
2786 | ||
2787 | E2fsck will create a /lost+found directory if there isn't one in the | |
2788 | filesystem, since it's safer to create the lost+found directory before | |
2789 | it's needed. | |
2790 | ||
2791 | Fixed e2fsck so that it would detect bogus immutable inodes which | |
2792 | happen to be sockets and FIFO files, and offer to clear them. | |
2793 | ||
2794 | If a filesystem has multiple reasons why it needs to be checked, and | |
2795 | one of the reasons is that it is uncleanly mounted, e2fsck will print | |
2796 | that as the reason why the filesystem is being checked. | |
2797 | ||
2798 | Cleaned up the output routines of mke2fs so that it doesn't overflow | |
2799 | an 80 column display when formating really big filesystems. | |
2800 | ||
2801 | Added a sanity check to e2fsck to make sure that file descriptors 0, | |
2802 | 1, 2 are open before opening the hard disk. This avoids a problem | |
2803 | where a broken program might exec e2fsck with those file descriptors | |
2804 | closed, which would cause disastrous results if the kernel returns a | |
2805 | file descriptor for the block device which is also used by FILE * | |
2806 | stdout. | |
2807 | ||
2808 | Fixed up the e2fsck progress reporting functions so that the values | |
2809 | reliably reach 100% at the completion of all of the e2fsck passes. | |
2810 | ||
2811 | Fixed minor documentation bugs in man pages and usage messages. | |
2812 | ||
2813 | Programmer's notes: | |
2814 | ------------------- | |
2815 | ||
2816 | Fixed a number of lint warnings in the ext2fs library and potential | |
2817 | portability problems from other OS's header files that might define | |
2818 | CPP macros for names like "max" and "min". | |
2819 | ||
2820 | ext2fs_badblocks_list_add() has been made more efficient when it needs | |
2821 | to grow the bad blocks list. | |
2822 | ||
2823 | Fixed a bug in e2fsck which caused it to dereference a freed pointer | |
2824 | just before exiting. | |
2825 | ||
2826 | Fixed the substition process for generating the mk_cmds and compile_et | |
2827 | scripts so that they will work outside of the build tree. | |
2828 | ||
2829 | Add sanity check to e2fsck so that if an internal routine | |
2830 | (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer | |

a569671a | 2833 | E2fsprogs 1.12 (July 9, 1998) |
21d53850 TT |
2834 | ================================== |
2835 | ||
2836 | E2fsprogs now works with glibc (at least with the version shipped wtih | |
2837 | RedHat 5.0). The ext2fs_llseek() function should now work even with | |
2838 | i386 ELF shared libraries and if llseek() is not present. We also | |
2839 | explicitly do a configure test to see if (a) llseek is in libc, and | |
2840 | (b) if llseek is declared in the system header files. (See standard | |
2841 | complaints about libc developers don't understand the concept of | |
2842 | compatibility with previous versions of libc.) | |
2843 | ||
c9833a60 TT |
2844 | The ext2fs library now writes out the block group number in each of |
2845 | the superblock copies. This makes it easier to automatically | |
2846 | determine the starting block group of the filesystem when the block | |
2847 | group information is trashed. | |
2848 | ||
2849 | Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature, | |
101c84f2 TT |
2850 | which means that e2fsprogs will ignore the high 8 bits of the |
2851 | directory entry's name_len field, so that it can be used for other | |
2852 | purposes. | |
2853 | ||
2854 | Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature. | |
2855 | E2fsprogs will now support filesystems with 64-bit sized files. | |
2856 | ||
2857 | Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature. | |
2858 | ||
21d53850 TT |
2859 | Added new program "e2label", contributed by Andries Brouwer. E2label |
2860 | provides an easy-to-use interface to modify the filesystem label. | |
2861 | ||
a4b2d3ce TT |
2862 | Fixed bug so that lsattr -v works instead of producing a core dump. |
2863 | ||
21d53850 TT |
2864 | Fixed a minor bug in mke2fs so that all groups with bad superblock |
2865 | backup blocks are printed (not just the first one). | |
a4b2d3ce TT |
2866 | |
2867 | Mke2fs will check the size of the device, and if the user specifies a | |
2868 | filesystem size larger than the apparent size of the device it will | |
2869 | print a warning message and ask if the user wants to proceed. | |
2870 | ||
c9833a60 TT |
2871 | E2fsck has a new option -C, which sends completion information to the |
2872 | specified file descriptor. For the most part, this is intended for | |
2873 | programs to use, although -C 0 will print a spinning character to the | |
2874 | stdout device, which may be useful for users who want to see something | |
2875 | happening while e2fsck goes about its business. | |
2876 | ||
21d53850 TT |
2877 | Fixed a bug in e2fsck which could cause a core dump when it needs to |
2878 | expand the /lost+found directory, and sometimes the bitmaps haven't | |
2879 | been merged in. Also fixed a related bug where ext2fs_write_dir_block | |
2880 | was used to write out a non-directory block. (Which would be bad on a | |
2881 | non-Intel platform with byte swapping going on.) | |
2882 | ||
2883 | Fixed bug in e2fsck where it would print a "programming error" message | |
2884 | instead of correctly identifying where a bad block was in used when | |
2885 | the bad block was in a non-primary superblock or block group | |
2886 | descriptor. Also fixed a related bug when sparse superblocks are in | |
2887 | use and there is a bad block where a superblock or block group | |
2888 | descriptor would have been in a group that doesn't include a | |
2889 | superblock. | |
2890 | ||
2891 | Fixed a bug in e2fsck (really in libext2fs's dblist function) where if | |
2892 | the block group descriptor table is corrupt, it was possible to try to | |
2893 | allocate a huge array, fail, and then abort e2fsck. | |
2894 | ext2fs_get_num_dirs() now sanity checks the block group descriptor, | |
2895 | and subsitutes reasonable values if the descriptors are obviously bogus. | |
2896 | ||
2897 | If e2fsck finds a device file which has the immutable flag set and the | |
2898 | i_blocks beyond the normal device number are non-zero, e2fsck will | |
2899 | offer to remove it, since it's probably caused by garbage in the inode | |
2900 | table. | |
2901 | ||
2902 | When opening a filesystem, e2fsck specially checks for the EROFS error | |
2903 | code, and prints a specific error message to the user which is more | |
2904 | user friendly. | |
2905 | ||
2906 | If the filesystem revision is too high, change the e2fsck to print | |
2907 | that this is either because e2fsck is out of date, or because the | |
2908 | superblock is corrupt. | |
2909 | ||
2910 | E2fsck now checks for directories that have duplicate '.' and '..' | |
2911 | entries, and fixes this corruption. | |
2912 | ||
2913 | E2fsck no longer forces a sync of the filesystem (with attendant sleep | |
2914 | calls) at all times. The ext2fs_flush() function now performs a sync | |
2915 | only if it needed to write data blocks to disk. | |
2916 | ||
2917 | Fixed a minor bug in e2fsck's pass1b's file cloning function, where | |
2918 | certain errors would not be properly reported. | |
2919 | ||
2920 | Updated and expanded a few points in the man pages which users | |
2921 | complained wheren't explicit enough. | |
2922 | ||
2923 | Added special case byte-swapping code if compiling on the PowerPC, to | |
2924 | accomodate the strange big-endian variant of the ext2 filesystem that | |
2925 | was previously used on the PowerPC port. | |
2926 | ||
2927 | ||
2928 | Programmer's notes: | |
2929 | ------------------- | |
2930 | ||
2931 | Removed C++ keywords from the ext2fs libraries so that it could be | |
2932 | compiled with C++. | |
2933 | ||
2934 | E2fsck's internal organization has now been massively reorganized so | |
2935 | that pass*.c don't have any printf statements. Instead, all problems | |
2936 | are reported through the fix_problem() abstraction interface. E2fsck | |
2937 | has also been revamped so that it can be called as a library from a | |
2938 | application. | |
2939 | ||
2940 | Added new fileio primitives in libext2fs for reading and writing | |
2941 | files on an unmounted ext2 filesystem. This interface is now used by | |
2942 | debugfs. | |
2943 | ||
2944 | Added a new libext2fs function for mapping logical block numbers of | |
2945 | a file to a physical block number. | |
2946 | ||
2947 | Added a new libext2fs function, ext2fs_alloc_block(), which allocates | |
2948 | a block, zeros it, and updates the filesystem accounting records | |
2949 | appropriately. | |
2950 | ||
2951 | Added a new libext2fs function, ext2fs_set_bitmap_padding(), which | |
2952 | sets the padding of the bitmap to be all one's. Used by e2fsck pass 5. | |
2953 | ||
2954 | The libext2fs functions now use a set of memory allocation wrapper | |
2955 | functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem, | |
2956 | instead of malloc, free, and resize. This makes it easier for us to | |
2957 | be ported to strange environments where malloc, et. al. aren't | |
2958 | necessarily available. | |
2959 | ||
2960 | Change the libext2fs fucntion to return ext2-specific error codes | |
2961 | (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using | |
2962 | and depending on the existence of system error codes (such as EEXIST | |
2963 | and ENOENT). | |
2964 | ||
2965 | Renamed io.h to ext2_io.h to avoid collision with other OS's header | |
2966 | files. | |
2967 | ||
2968 | Add protection against ext2_io.h and ext2fs.h being included multiple | |
2969 | times. | |
2970 | ||
2971 | The types used for memory lengths, etc. have been made more portable. | |
2972 | In generla, the code has been made 16-bit safe. Added Mark | |
2973 | Habersack's contributed DOS disk i/o routines. | |
2974 | ||
2975 | Miscellaneous portability fixes, including not depending on char's | |
2976 | being signed. | |
2977 | ||
2978 | The io_channel structure has a new element, app_data, which is | |
2979 | initialized by the ext2fs routines to contain a copy of the filesystem | |
2980 | handle. | |
2981 | ||
2982 | ext2fs_check_directory()'s callback function may now return the error | |
2983 | EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to | |
2984 | really do the checking, despite the presence of the callback function. | |
2985 | ||
2986 | ||
bc210074 TT |
2987 | E2fsprosg 1.11 (June 17, 1997) |
2988 | ============================== | |
2989 | ||
2990 | Fixed e2fsck to detect (previously ignored) conflicts between the | |
2991 | superblock or block group descriptors and block bitmaps, inode | |
2992 | bitmaps, and inode tables. | |
2993 | ||
2994 | Fixed bug in e2fsck so that when the message printed out when a block | |
2995 | or inode bitmap conflicts with other data, it has the correct group | |
2996 | number. | |
2997 | ||
2998 | Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed | |
2999 | to badblocks. This meant that not all of the filesystem was being | |
3000 | tested for bad blocks! | |
3001 | ||
3002 | Fixed an array boundary overrun case which cropped up in | |
3003 | ext2fs_badblocks_list_test when a user tried running "mke2fs -c | |
3004 | -b 4096". | |
3005 | ||
3006 | Adjusted the number of columns printed by mke2fs when displaying the | |
3007 | superblock backups to avoid running over 80 columns when making a | |
21d53850 | 3008 | really big filesystem. |
bc210074 TT |
3009 | |
3010 | Fixed up the man pages for e2fsck, debugfs, badblocks, chattr, | |
3011 | dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar | |
3012 | fixes), thanks to some suggestions from Bill Hawes (whawes@star.net). | |
3013 | ||
3014 | Programmer's notes: | |
3015 | ------------------- | |
3016 | ||
3017 | Fixed install rule in lib/ss so that ss_err.h is actually getting | |
3018 | installed. | |
3019 | ||
3020 | Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting | |
3021 | bassed back to the caller. | |
3022 | ||
3023 | Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been | |
3024 | setting the current inode number (which meant this function wasn't | |
3025 | working at all). | |
3026 | ||
3027 | Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all | |
3028 | blocks in the bitmap when increasing the size of the bitmap. | |
3029 | ||
3030 | Changed the initial number of blocks allocated by ext2fs_init_dblist() | |
3031 | to be more realistic. | |
3032 | ||
3033 | Added a new function ext2fs_allocate_group_table, which sets up the | |
3034 | group descriptor information (and allocates inode and block bitmaps, | |
3035 | and inode tables for a particular group). The function was created by | |
3036 | factoring out code form ext2fs_allocate_tables(). | |
3037 | ||
3038 | Added a new function ext2fs_move_blocks which takes a bitmap of the | |
3039 | blocks to be moved, and moves them to another location on the | |
3040 | boardboard. | |
3041 | ||
3042 | Make the unix_io channel's io_channel_flush implementation calls sync() | |
3043 | to to flush the kernel buffers to disk. | |
3044 | ||
3045 | Added a new function ext2fs_dblist_count returns the number of | |
3046 | directory blocks in dblist. | |
3047 | ||
3048 | ||
ae851482 TT |
3049 | E2fsprogs 1.10 (April 24, 1997) |
3050 | =============================== | |
3051 | ||
3052 | Mke2fs once again defaults to creating revision #0 filesystems, since | |
3053 | people were complaining about breaking compatibility with 1.2 kernels. | |
3054 | Warning messages were added to the mke2fs and tune2fs man pages that | |
3055 | the sparse superblock option isn't supported by most kernels yet (1.2 | |
3056 | and 2.0 both don't support parse superblocks.) | |
3057 | ||
3058 | Added new flag to mke2fs, -R <raid options>, which allows the user to | |
3059 | tell mke2fs about the RAID configuration of the filesystem. Currently | |
3060 | the only supported raid option is "stride" which specifies the width | |
3061 | of the RAID stripe. | |
3062 | ||
3063 | Fixed bug in e2fsck where pass1b would bomb out if there were any | |
3064 | blocks marked bad in the inode table. | |
3065 | ||
3066 | Fixed rare bug in mke2fs where if the user had a very unlucky number | |
3067 | of blocks in a filesystem (probability less than .002) the resulting | |
3068 | filesystem would be corrupt in the last block group. | |
3069 | ||
3070 | Fixed bug where if e2fsck tried to allocate a block to fix a | |
3071 | filesystem corruption problem and the filesystem had no free blocks, | |
3072 | ext2fs_new_block() would loop forever. | |
3073 | ||
3074 | The configure script now checks explicitly to see if "-static" works, | |
3075 | since that can't be assumed to be true --- RedHat doesn't install | |
3076 | libc-static by default. | |
3077 | ||
3078 | Fixed bug in libext2's block iterator functions where under some | |
3079 | cirmcustances, file with holes would cause the bcount parameter to the | |
3080 | callback function to be incorrect. This bug didn't affect any of | |
3081 | e2fsprogs programs, but it was discovered by Paul Mackerras, the | |
3082 | author of the PPC boot loader. | |
3083 | ||
3084 | Removed use of static variables to store the inode cache in libext2fs. | |
3085 | This caused problems if more than one filesystem was accessed via | |
3086 | libext2fs (static variables in libraries are generally a bad idea). | |
3087 | Again, this didn't affect e2fsprogs programs, but it was discovered by | |
3088 | Paul Mackerras. | |
3089 | ||
3090 | Fixed minor bugs and version code drift to assure that e2fsprogs 1.10 | |
3091 | will compile cleanly with 1.2.13 kernels (even with a.out shared | |
3092 | libraries!) | |
3093 | ||
3094 | Programmer's notes: | |
3095 | ------------------- | |
3096 | ||
3097 | Added new functions to duplicate an ext2 filesystem handle, and its | |
3098 | associated substructure. New functions: ext2fs_dup_handle(), | |
3099 | ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap(). | |
3100 | Other structures, such as the io_channel and the inode_cache, now have | |
3101 | a ref count so that they only get freed when they are no longer used | |
3102 | by any filesystem handle. (These functions were added as part of the | |
3103 | development effort for an ext2 resizer). | |
3104 | ||
2ecc6fef TT |
3105 | E2fsprogs 1.09 (April 14, 1997) |
3106 | =============================== | |
3107 | ||
3108 | Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was | |
3109 | accidentally introduced in the 1.08 release. The overhead calculation | |
3110 | was accidentally removed, which caused ext2fs_initialize() to not | |
3111 | notice when the filesystem size needed to be adjusted down because | |
3112 | there wasn't enough space in the last block group. | |
3113 | ||
3114 | Fixed bug in version parsing library routine; it was always parsing | |
3115 | the library version string, instead of using the passed-in string. | |
3116 | ||
3117 | Clarified chattr man page. | |
3118 | ||
24757fa0 TT |
3119 | E2fsprogs 1.08 (April 10, 1997) |
3120 | =============================== | |
3121 | ||
3122 | E2fsck 1.07 was very slow when checking very large filesystems with a | |
3123 | lot of files that had hard links (i.e., news spools). This was fixed | |
3124 | by seriously revamping the icount abstraction. Added a formal test | |
3125 | suite for the icount abstraction. | |
3126 | ||
3127 | Debugfs now has a "-l" option to the "ls" command, which lists the | |
3128 | inode number, permissions, owner, group, size, and name of the files | |
3129 | in the directory. | |
3130 | ||
3131 | Fix a bug in e2fsck where when a directory had its blocks moved to | |
3132 | another location during the pass 1b processing, the directory block | |
3133 | list wasn't updated, so pass 2 wouldn't check (and correct) the | |
3134 | correct directory block. | |
3135 | ||
3136 | E2fsck will now treat inodes which contain blocks which are claimed by | |
3137 | the filesystem metadata by treating them as multiply claimed blocks. | |
3138 | This way, the data in those blocks can be copied to a new block during | |
3139 | the pass 1b--1d processing. | |
3140 | ||
3141 | E2fsck will attempt to determine the correct superblock number and | |
3142 | display it in the diagnostic and warning messages if possible. | |
3143 | ||
3144 | Add support for a new (incompatible) feature, "sparse_super". This | |
3145 | feature reduces the number of blocks which contain copies of backup | |
3146 | superblocks and block group descriptors. (It is only an incompatible | |
3147 | feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now | |
3148 | support a new -s option; e2fsck will recognize filesystems built with | |
3149 | this feature turned on. | |
3150 | ||
3151 | E2fsck now checks the library to make sure is the correct version, | |
3152 | using new library functions. (This helps to diagnose incorrectly | |
3153 | installed e2fsprogs distributions.) | |
3154 | ||
3155 | Dumpe2fs now prints more information; its now prints the the | |
3156 | filesystem revision number, the filesystem sparse_super feature (if | |
3157 | present), the block ranges for each block group, and the offset from | |
3158 | the beginning of the block group. | |
3159 | ||
3160 | Mke2fs now distributes the inode and block bitmap blok so that the | |
3161 | won't be concentrated in one or two disks in RAID/striping setups. | |
3162 | Also, if the user chooses a 2k or 4k block group, mke2fs will try to | |
3163 | choose the largest blocks per group that be chosen. (For 2k blocks, | |
3164 | you can have up to 16384 blocks/group; for 4k blocks, you can have up | |
3165 | to 32768 blocks/group.) Previously mke2fs would not allow | |
3166 | specification of more than 8192 blocks per group, even if you were | |
3167 | using a 2k or 4k block group. | |
3168 | ||
3169 | Programmer's notes: | |
3170 | ------------------- | |
3171 | ||
3172 | Added a new function ext2fs_create_icount2() which takes a "hint" | |
3173 | argument. This hint argument presets the icount array with the list | |
3174 | of inodes which actually need to be in the icount array. This really | |
3175 | helps to speed up e2fsck. | |
3176 | ||
3177 | Added a new function ext2fs_icount_validate() which checks the rep | |
3178 | invariant for the icount structure. This is used mostly for testing. | |
3179 | ||
3180 | The error mesasage given when a bad inode number is passed to | |
3181 | test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of | |
3182 | EXT2FS_UNMARK_ERROR). | |
3183 | ||
3184 | Added a new function ext2fs_set_dir_block which sets the block of a | |
3185 | dblist entry, given the directory inode and blockcnt. | |
3186 | ||
3187 | Added a new function ext2fs_get_library_version() which returns the | |
3188 | current library version, and ext2fs_parse_version_string() which | |
3189 | returns a version number based on a e2fsprogs version string. | |
3190 | ||
3191 | The icount functions will return EINVAL if the passed in inode number | |
3192 | is out of bounds. | |
3193 | ||
21c84b71 TT |
3194 | E2fsprogs 1.07 (March 9, 1997) |
3195 | ============================== | |
3196 | ||
3197 | E2fsck is now uses much less memory when checking really large | |
3198 | filesystems (or rather, filesystems with a large number of inodes). | |
3199 | Previously a filesystem with 1 million inodes required 4 megabytes of | |
3200 | memory to store inode count statistics; that storage requirement has | |
3201 | now been reduced to roughly half a megabyte. | |
3202 | ||
3203 | E2fsck can now properly deal with bad blocks appearing inside the | |
3204 | inode table. Instead of trying to relocate the inode table (which | |
3205 | often failed because there wasn't enough space), the inodes in the bad | |
3206 | block are marked as in use. | |
3207 | ||
3208 | E2fsck will automatically try to use the backup superblocks if the | |
3209 | primary superblocks have a bad magic number or have missing meta-data | |
3210 | blocks (or meta-data blocks which are out of range). | |
3211 | ||
3212 | E2fsck's pass 3 has been made more efficient; most noticeable on | |
3213 | filesystems with a very large number of directories. | |
3214 | ||
3215 | Completely revamped e2fsck's system of printing problem reports. It | |
3216 | is now table driven, to make them more easily customizeable and | |
3217 | extendable. Error messages which can be printed out during preen mode | |
3218 | are now one line long. | |
3219 | ||
3220 | Fixed e2fsck's filesystem swapping code so that it won't try to swap | |
3221 | fast symbolic links or deleted files. | |
3222 | ||
3223 | Fixed e2fsck core dumping when fixing a filesystem which has no | |
3224 | directories (not even a root directory). | |
3225 | ||
3226 | Added a check to e2fsck to make sure that the length of every | |
3227 | directory entry is a multiple of 4 (since the kernel complains if it | |
3228 | isn't). | |
3229 | ||
3230 | Added a check to e2fsck to make sure that a directory entry isn't a | |
3231 | link to the root directory, since that isn't allowed. | |
3232 | ||
3233 | Added a check to e2fsk to now make sure the '.' and '..' directory | |
3234 | entries are null terminated, since the 2.0 kernel requires it. | |
3235 | ||
3236 | Added check to write_bitmaps() to make sure the superblock doesn't get | |
3237 | trashed if the inode or block bitmap is marked as being block zero. | |
3238 | ||
3239 | Added checking of the new feature set fields in the superblock, to | |
3240 | avoid dealing with new filesystem features that this package wasn't | |
3241 | set up to handle. | |
3242 | ||
3243 | Fixed a fencepost error in ext2fs_new_block() which would occasionally | |
3244 | try to allocate a block beyond the end of a filesystem. | |
3245 | ||
3246 | When the UUID library picks a random IEEE 802 address (because it | |
3247 | can't find one from a network card), it sets the multicast bit, to | |
3248 | avoid conflicting with a legitimate IEEE 802 address. | |
3249 | ||
3250 | Mke2fs now sets the root directory's owner to be the real uid of the | |
3251 | user running mke2fs. If the real uid is non-zero, it also sets | |
3252 | the group ownership of the root directory to be the real group-id of | |
3253 | the user running mke2fs. | |
3254 | ||
3255 | Mke2fs now has more intelligent error checking when it is given a | |
3256 | non-existent device. | |
3257 | ||
3258 | When badblocks is given the -vv option, it now updates the block that | |
3259 | it is currently testing on every block. | |
3260 | ||
3261 | Fixed a bug in fsck where it wouldn't modify the PATH envirnoment | |
3262 | currently correctly if PATH wasn't already set. | |
3263 | ||
3264 | Shared libraries now built with dependencies. This allows the shared | |
3265 | library files to be used with dlopen(); it also makes the transition | |
3266 | to libc 6 easier, since ld.so can tell which libc a particular shared | |
3267 | library expects to use. | |
3268 | ||
3269 | Programmer's notes: | |
3270 | ------------------- | |
3271 | ||
3272 | Added new abstraction (defined in dblist.c) for maintaining a list of | |
3273 | blocks which belongs to directories. This is used in e2fsck and other | |
3274 | programs which need to iterate over all directories. | |
3275 | ||
3276 | Added new functions which test to see if a contiguous range of blocks | |
3277 | (or inodes) are available. (ext2fs_*_bitmap_range). | |
3278 | ||
3279 | Added new function (ext2_inode_has_valid_blocks) which returns true if | |
3280 | an inode has valid blocks. (moved from e2fsck code). | |
3281 | ||
3282 | Added new function (ext2fs_allocate_tables) which allocates the | |
3283 | meta-data blocks as part of initializing a filesystem. (moved from | |
3284 | mke2fs code). | |
3285 | ||
3286 | Added a new I/O manager for testing purposes. It will either allow a | |
3287 | program to intercept I/O requests, or print debugging messages to | |
3288 | trace the activity of a program using the I/O manager. | |
3289 | ||
3290 | The badblocks_list functions now store the bad blocks in a sorted | |
3291 | order, and use a binary search to speed up badblocks_list_test. | |
3292 | ||
3293 | The inode scan function ext2fs_get_next_inode() may now return a soft | |
3294 | error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in | |
3295 | those cases where part of an inode table is missing or there is a bad | |
3296 | block in the inode table. | |
3297 | ||
3298 | Added a new function (ext2fs_block_iterate2) which adds new arguments to | |
3299 | the callback function to return a pointer (block and offset) to the | |
3300 | reference of the block. | |
3301 | ||
3302 | Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an | |
3303 | application to jump to a particular block group while doing an inode | |
3304 | scan. | |
3305 | ||
3306 | The badblocks list functions were renamed from badblocks_* to | |
3307 | ext2fs_badblocks_*. Backwards compatibility functions are available | |
3308 | for now, but programs should be modified to use the new interface. | |
3309 | ||
3310 | Some of the library functions were reorganized into separate files to | |
3311 | reduce the size of some programs which statically link against the | |
3312 | ext2 library. | |
3313 | ||
3314 | Put in some miscellaneous fixes for the Alpha platform. | |

3317 | E2fsprogs 1.06 (October 7, 1996) | |
3318 | ================================ | |
3319 | ||
3320 | Fixed serious bug in e2fsck: if the block descriptors are bad, don't | |
3321 | smash the backup copies in ext2fs_close(). (The problem was that when | |
3322 | e2fsck -p discovered the problem, while it was closing the filesystem | |
3323 | and exiting, it was also blowing away the backup superblocks on the | |
3324 | disk, which was less than friendly.) We now make it the case that we | |
3325 | only write out the backup superblock and the back block descriptors if | |
3326 | the filesystem is completely free from problems. | |
3327 | ||
3328 | Fixed a bug in block_interate in the lib/ext2fs library which caused | |
3329 | e2fsck to fail on GNU Hurd-created filesystems. | |
3330 | ||
3331 | Add support for Linux/FT's bootloader, which actually uses | |
3332 | EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want | |
3333 | to clear the inode. | |
3334 | ||
3335 | Add support for the "A" (no atime update) attribute. (Note: this | |
3336 | attribute is not yet in production kernels.) | |
3337 | ||
3338 | The test suite is not automatically run when doing a "make all" from | |
3339 | the top level directory. Users should manually run "make check" if | |
3340 | they wish to run the test suite. | |
3341 | ||
3342 | Upon a preenhalt(), make the printed message more explicit that | |
3343 | running e2fsck "MANAULLY" means without the -p or -a options. | |
3344 | ||
3345 | In e2fsck, if a disconnected inode is zero-length, offer to clear it | |
3346 | instead of offering to connect it to lost+found. | |
3347 | ||
3348 | In e2fsck, if a filesystem was just unmounted uncleanly, and needs | |
3349 | e2fsck to be run over it, change e2fsck to explicitly display this | |
3350 | fact. | |
3351 | ||
3352 | For dumpe2fs and e2fsck, cause the -V option to print out which | |
3353 | version of the ext2fs library is actually getting used. (This will | |
3354 | help detect mismatches of using a 1.06 utility with a 1.05 library, | |
3355 | etc.) | |
3356 | ||
3357 | Programmers' notes: | |
3358 | ------------------- | |
3359 | ||
3360 | EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits | |
3361 | the naming convention. | |
3362 | ||
3363 | In ext2fs_initialize(), make sure the description for the inode bitmap | |
3364 | is correctly initialize. | |
3365 | ||
3366 | Fixed minor type typo in ext2fs_allocate_generic_bitmap(); | |
3367 | ||
fc6d9d51 TT |
3368 | E2fsprogs 1.05 (September 7, 1996) |
3369 | ================================== | |
3370 | ||
3371 | Add support for new fields in the ext2 superblock --- volume name, | |
3372 | volume UUID, and last mounted field. Dumpe2fs displays these fields, | |
3373 | tune2fs and mke2fs allows you to set them. E2fsck will automatically | |
3374 | generate a UUID for those volumes that don't have them. | |
3375 | ||
3376 | Put in support for e2fsck to recognize HURD specific ext2 features --- | |
3377 | most notably, the translator block. The e2fsprogs tools will now use | |
3378 | the creator_os field in the superblock to correctly handle different | |
3379 | OS-specific variants of the ext2 filesystem. | |
3380 | ||
3381 | E2fsck now fixes inodes which have a the deletion time set, but which | |
3382 | have a non-zero i_link_count field by offering to clear the deletion | |
3383 | time. Previously e2fsck assumed that the inode was deleted (per 0.3c | |
3384 | ext2 kernel behavior) and offered to unlink the file. | |
3385 | ||
3386 | If e2fsck sets the clean bit, but nothing else, set the exit code | |
3387 | FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it | |
3388 | set the filesystem valid bit when it was previously cleared. :-) This | |
3389 | was needed to make the HURD fsck driver happy. | |
3390 | ||
3391 | If the user refuses to attach an unattached inode, e2fsck will no | |
3392 | longer set the inode's link count. Otherwise, the inode would end up | |
3393 | getting marked as unused, which might cause loss of data later. | |
3394 | ||
3395 | Make the message issued by e2fsck when the superblock is corrupt less | |
3396 | confusing for users. It now mentions that another reason for the | |
3397 | "corrupt superblock" message might be that the partition might not be | |
3398 | an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.) | |
3399 | ||
3400 | Make the libext2 library more robuest so that e2fsck won't coredump on | |
3401 | an illegal superblock where the blocksize is zero. (f_crashdisk is | |
3402 | the test case). | |
3403 | ||
3404 | By default, create filesystems where the default checkinterval is 6 | |
3405 | months (180 days). Linux servers can be robust enough that 20 reboots | |
3406 | can be a long, long time. | |
3407 | ||
3408 | Added configure flag --enable-old-bitops, which forces the bitops to | |
3409 | use the old (native) bitmask operations. By default on the sparc | |
3410 | platform, the standard ext2 bit ordering is now used. | |
3411 | ||
3412 | Added a new feature to e2fsck to byte-swap filesystems; this can be | |
3413 | used to convert old m68k filesystems to use the standard byte-order | |
3414 | storage for the superblock, inodes, and directory blocks. This | |
3415 | function is invoked by using the '-s' option to e2fsck. | |
3416 | ||
3417 | Debugfs's "dump" command has been enhanced so that it writes out the | |
3418 | exact size of the file so that the nulls at the end of the file are | |
3419 | eliminated. The command also accept a new "-p" option which will | |
3420 | attempt preserve to preserve the ownernship, permissions, and | |
3421 | file modification/access times. | |
3422 | ||
3423 | Debugfs has two new options, -f and -R. The -R option allows the user | |
3424 | to execute a single debugfs command from the command line. The -f | |
3425 | option allows the user to specify a "command file" containing debugfs | |
3426 | commands which will get executed. | |
3427 | ||
3428 | Dumpe2fs now pretty prints the check interval, instead of just | |
3429 | printing the check interval as a number of seconds. | |
3430 | ||
3431 | Fix bugs in debugfs: the params command when no filesystem is opened | |
3432 | no longer causes a core dump. It is now possible to unlink a file | |
3433 | when a pathame containing a '/' is specified. | |
3434 | ||
3435 | Tune2fs has a new -C option which sets the number of times the | |
3436 | filesystem has been mounted. | |
3437 | ||
3438 | Fix the chattr '-v' option so that it actually works. Chattr was | |
3439 | being buggy about the -v option parsing. | |
3440 | ||
3441 | Programmers' notes: | |
3442 | ------------------- | |
3443 | ||
3444 | The directory lib/uuid contains a set of library routines to generate | |
3445 | DCE compatible UUIDs. | |
3446 | ||
3447 | Extended ext2fs_namei() to handle symbolic links. Added new function | |
3448 | ext2fs_nami_follow() which will follow last symbolic link in the case | |
3449 | where the pathname points to a sym link. | |
3450 | ||
3451 | The ext2fs_block_iterate function will now return the HURD translator | |
3452 | block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the | |
3453 | iterator to return data blocks only. The ext2fs.h file now defines | |
3454 | constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and | |
3455 | BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block | |
3456 | count field of the iterator callback function. | |
3457 | ||
3458 | The test script driver now takes an optional second argument, which is | |
3459 | the test case to be run. This allows you to run a test case without | |
3460 | needing to run the entire test suite. | |
3461 | ||
3462 | On Linux ELF systems, install the .so files in the correct places | |
3463 | (/usr/lib). The .so files must be stored in the same directory as the | |
3464 | .a files. | |
3465 | ||
3466 | Fixed miscellaneous HURD compilation issues with header file being | |
3467 | included in the right order. | |
3468 | ||
3469 | Fixed debugfs so that it resets optind to zero, not one, since setting | |
3470 | optind to zero is more correct. | |
3471 | ||

3473 | E2fsprogs 1.04 (May 16, 1996) |
3474 | ============================= | |
3475 | ||
3476 | First "official" (1.03 was a limited release only) to support building | |
3477 | e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99 | |
3478 | kernels). | |
3479 | ||
3480 | This package includes a RPM specs file, that it can be built using the | |
3481 | RedHat Package Manager. | |
3482 | ||
3483 | E2fsck now prints a hint that if there are lots of incorrectly located | |
3484 | inode bitmaps, block bitmaps, and inode table blocks, the user might | |
3485 | want to try using e2fsck -b 8193 first, to see if that fares any | |
3486 | better. | |
3487 | ||
3488 | For ext2 filesystem written with the hurd, debugfs will now print out | |
3489 | the translator field when printing an inode structure. | |
3490 | ||
3491 | Lots of miscellaneous linking/installation cleanups: | |
3492 | ||
3493 | Libraries are now linked using a relative pathname, instead of | |
3494 | relying on -L working correct. It doesn't, in many cases, including | |
3495 | current versions of GNU ld. This guarantees that the build tree is | |
3496 | linking with the right libraries, instead of the ones installed in | |
3497 | /usr/lib. | |
3498 | ||
3499 | Header files, man pages, and the et/ss shell scripts are now | |
3500 | generated using a custom substitution script, instead of relying on | |
3501 | the configure script. This prevents needless recompilation of | |
3502 | files; in addition, the custom substitution script is much faster. | |
3503 | ||
3504 | e2fsck may now be linked dynamically, by using the | |
3505 | --enable-dynamic-e2fsck flag to configure. This is not recommended, | |
3506 | since it increases e2fsck's dependence on other files, but some | |
3507 | people need to save disk space, and other critical programs on their | |
3508 | systems were being linked dynamically anyway. | |
3509 | ||
3510 | Programs such as fsck which didn't need to be linked against | |
3511 | libext2fs (or mke2fs which didn't need to be linked against libe2p) | |
3512 | only link against libraries they actually need. Otherwise, those | |
3513 | programs would require the presense of libraries that otherwise | |
3514 | could be removed from a rescuse diskette. | |
3515 | ||
3516 | The ss include files are now installed correctly so they can | |
3517 | actually be used by another package. | |
3518 | ||
3519 | If the profiling libraries are built, they are now installed on a | |
3520 | "make install-libs". | |
3521 | ||

7f88b043 TT |
3523 | E2fsprogs 1.03 (March 27, 1996) |
3524 | =============================== | |
3525 | ||
3526 | Change the m68k bit numbering for bitmasks to match the bit numbering | |
3527 | used by all other ext2 implementations. (This change was requested by | |
3528 | the m68k kernel development team.) | |
3529 | ||
3530 | Support (in-development) filesystem format revision which supports | |
3531 | (among other things) dynamically sized inodes. | |
3532 | ||
3533 | Fixed a bug in the ext2 library so that an intelligent error is | |
3534 | returned if mke2fs is run with a ridiculously small number of blocks | |
3535 | for a partition. | |
3536 | ||
3537 | Fixed a bug in the ext2 library which required that the device be | |
3538 | openable in read/write mode in order to determine its size. This | |
3539 | caused e2fsck -n to require read/write access when it was not | |
3540 | previously necessary. | |
3541 | ||
3542 | Fixed a bug in e2fsck which casued it to occasionally fail the test | |
3543 | suite depending on which version of the floating point library it was | |
3544 | using. | |
3545 | ||
3546 | Fixed a bug in e2fsck so that it now halts with a fatal error when | |
3547 | certain superblock consistency checks fail. Previously it continued | |
3548 | running e2fsck, with some potential confusing/damaging consequences. | |
3549 | ||
3550 | Added new flag to fsck which allows the root to be checked in parallel | |
3551 | with other filesytems. This is not the safest thing in the world to | |
3552 | do, but some system administrators really wanted it. | |
3553 | ||
fc6d9d51 TT |
3554 | Fixed -Wall flames in lib/ss. |

74becf3c TT |
3556 | |
3557 | E2fsprogs 1.02 (January 16, 1996) | |
3558 | ================================= | |
3559 | ||
3560 | Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels. | |
3561 | ||
3562 | Change e2fsck to print statistics of how many non-contiguous files are | |
3563 | on the system. Note that a file which is larger than 8k blocks, it is | |
3564 | guaranteed to be non-contiguous. | |
3565 | ||
3566 | In mke2fs, print a warning message if a user tries to format a whole | |
3567 | disk (/dev/hda versus /dev/hda1). If a user really wants to format a | |
3568 | whole disk, the -F (force) option forces mke2fs to format a whole disk | |
3569 | as a filesytem. | |
3570 | ||
3571 | Fix a bug in fsck where in some cases it might start checking | |
3572 | partitions in the next pass before it finishes checking partitions in | |
3573 | the current pass. This still won't cause two partitions on the same | |
3574 | disk will be checked, so it's rarely a problem in real life. | |
3575 | ||
3576 | Patch lsattr so that it won't hang when checking a named pipe. | |
3577 | ||
3578 | Minor compilation fixes: | |
3579 | * Fix the order of libraries that were linked in debugfs. | |
3580 | * Allow the sources to be compiled with -ansi turned on. |
