2 | ||
3 | Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005) | |
4 | ================================================================= | |
5 | ||
6 | 1. Changed restore to emit warnings (instead of emitting a fatal | |
7 | error) if a file (or a directory) is unavailable for a | |
8 | comparision (if the user doesn't have the necessary permissions | |
9 | to access it for example). Thanks to Kenneth Porter | |
10 | <shiva@sewingwitch.com> for the bug report. | |
11 | ||
12 | 2. Re-done the 'do not save directory entries to non-dumped inodes | |
13 | (excluded from dump)' feature. The previous implementation | |
14 | worked well for excluded directories but not for regular files. | |
15 | Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug | |
16 | report. | |
17 | ||
18 | 3. Fixed a bug in dump where the tape size was miscalculated when | |
19 | the user used -d/-s to specify the tape characteristics. Thanks | |
20 | to Philip Goisman <goisman@physics.arizona.edu> for reporting | |
21 | the bug. | |
22 | ||
23 | 4. Fixed another bug introduced in restore with the hashtree | |
24 | implementation. This one caused restore to stop saying | |
25 | "removenode: non-empty directory" in some cases. | |
26 | ||
27 | 5. Added support for dumping and restoring ext2/3 extended | |
28 | attributes (EA), like the access control lists (ACL) or | |
29 | the security labels used by SELinux. | |
30 | ||
31 | Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005) | |
32 | ====================================================================== | |
33 | ||
34 | 1. The newly added dump_on_cd_3 example was buggy, replace it | |
35 | with an updated version from Andrew Basterfield | |
36 | <bob@cemetery.homeunix.org>. | |
37 | ||
38 | 2. Made restore to chdir() back into the initial directory when | |
39 | dumping core while aborting a comparision operation. The | |
40 | previous behaviour was to write the corefile at the root of | |
41 | the directory being compared, which could very well be | |
42 | read only and preventing the corefile generation. Thanks | |
43 | to Kenneth Porter <shiva@sewingwitch.com> for the bug report. | |
44 | ||
45 | 3. Silenced the failure to call fgetflags() when comparing an | |
46 | entry which has no ext2 attributes (as in lsattr()). | |
47 | ||
48 | 4. Fix a brown paper bug in restore -C which broke restore and | |
49 | caused modifications on the filesystem being compared | |
50 | (directories containing a file with the same name as the | |
51 | directory get renamed to RSTTMP...). Thanks to Kenneth Porter | |
52 | <shiva@sewingwitch.com> for finding the bug and helping me | |
53 | reproduce it. | |
54 | ||
55 | 5. Made restore -C force the -N flag (no writing allowed on | |
56 | the disk) in order to prevent more bugs like the above one. | |
57 | ||
58 | Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005) | |
59 | ===================================================================== | |
60 | ||
61 | 1. Fix a couple of troff syntax bugs in the man pages. | |
62 | Thanks to Eric Raymond <esr@thyrsus.com> for the patch. | |
63 | ||
64 | 2. Made restore use either libncurses or libtermcap, depending | |
65 | on which one is available at configure time. | |
66 | ||
67 | 3. Fixed restore negative size display bug when comparing a | |
68 | dump containing files over 2GB. Thanks to Steve Bonds | |
69 | <sbonds@users.sourceforge.net> for the bug report. | |
70 | ||
71 | 4. Do not save directory entries to non-dumped inodes | |
72 | (excluded from dump). This will eliminate the 'missing | |
73 | file' warnings when doing 'restore -C'. | |
74 | ||
75 | 5. Fix dump crash when backuping a huge (2TB) filesystem, | |
76 | due to a bogus calculation on the inode map size. | |
77 | Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for | |
78 | submitting the bug and testing the fix. | |
79 | ||
80 | 6. Fix a problem in restore where the final \0 in the symbolic | |
81 | link names could have been lost, generating corrupt filenames. | |
82 | Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the | |
83 | bug. | |
84 | ||
85 | 7. Implemented a hash list for the directory names in restore. | |
86 | The linear list used before caused problems in interactive | |
87 | restores when dealing with directories having thousands of | |
88 | entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com> | |
89 | for reporting the bug. | |
90 | ||
91 | 8. Improved restore -C, this time including the directory | |
92 | attributes into the comparision. | |
93 | ||
94 | 9. Made restore understand tapes containing EA/ACLs (which will | |
95 | be dumped by the next version of dump). In this version | |
96 | extended attributes on the tape are ignored, for full EA/ACL | |
97 | support wait for the next version or try the experimental EA | |
98 | patch. | |
99 | ||
100 | Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004) | |
101 | ================================================================== | |
102 | ||
103 | 1. Added the --enable-staticz configure option which enables | |
104 | dump and restore to be linked with static versions of | |
105 | libz and libbz2 (and dynamic versions of all other libraries). | |
106 | This will make Debian users happy, because libz and libbz2 | |
107 | were the only needed libraries living in /usr, all the | |
108 | others live in /lib. In case of system emergency, it is | |
109 | better not to have to rely on an extra filesystem. | |
110 | Thanks to Bdale Garbee <bdale@gag.com> for the suggestion. | |
111 | ||
112 | 2. Fix compilation on (at least the Linux Debian port to) AMD64. | |
113 | (<ext2fs/ext2_types.h> defines some types (__s64 and __u64) | |
114 | that are also defined by <linux/types.h> (<asm/types.h>) and | |
115 | they conflict). | |
116 | ||
117 | 3. Make dump's reading of the dumpdates file a bit more robust, | |
118 | preventing dump from crashing when the dumpdates file has | |
119 | been modified by hand. | |
120 | ||
121 | 4. Fixed some offset calculations in dump code which could | |
122 | lead to "bread lseek errors" on large filesystems. Thanks | |
123 | to Bruce Lowekamp <lowekamp@users.sourceforge.net> for | |
124 | reporting this bug and debugging the issue. | |
125 | ||
126 | 5. Made dump use the blkid library when searching for devices | |
127 | by label or uuid instead of dump's own routines. | |
128 | ||
129 | 6. Corrected a bug in dump where a wrong LABEL=... line in | |
130 | /etc/fstab could prevent dump from dumping unrelated | |
131 | filesystems. Thanks to Bruce Lowekamp | |
132 | <lowekamp@users.sourceforge.net> for reporting the bug. | |
133 | ||
134 | Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004) | |
135 | ==================================================================== | |
136 | ||
137 | 1. Fixed dump compilation with old gcc versions. Thanks to | |
138 | Mike Castle <dalgoda@users.sourceforge.net> for the patch. | |
139 | ||
140 | 2. Fixed some warnings (howmany, roundup, powerof2 redefined) | |
141 | when compiling against a recent glibc version. | |
142 | ||
143 | 3. Fixed a bug in restore preventing the read of a dump tape | |
144 | written with Solaris 7 ufsdump. Thanks to Patrick Higgins | |
145 | <phiggins@transzap.com> for reporting the bug and providing | |
146 | the test case. | |
147 | ||
148 | 4. Changed dump to enable the creation of volumes of different | |
149 | sizes in a single run (make -B accept a list of values). | |
150 | Patch contributed by Florian Zumbiehl <florz@gmx.de>. | |
151 | ||
152 | 5. Use the glibc provided minor() and major() macros instead | |
153 | of our own bitmask implementation. This should be safe for | |
154 | when the major/minor namespace will migrate to 32 bits. | |
155 | Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting | |
156 | the bug. | |
157 | ||
158 | 6. Made explicit in the dump man page that dump will not create | |
159 | a remote file, it will only write to an already existing one. | |
160 | ||
161 | 7. Another try at making size estimates better again. | |
162 | ||
163 | 8. Put back the inconditional running of the end-of-tape | |
164 | script which was changed in 0.434 to be run only when -M | |
165 | or multiple -f were NOT specified. Some users rely on this | |
166 | feature even when it is combined with -M/-f. | |
167 | ||
168 | 9. Fixed restore when restoring huge backups (where rstdir... | |
169 | temporary files are over 2GB). Thanks to | |
170 | Raphael Jaffey <rjaffey@artic.edu> for reporting this, | |
171 | debugging the issue and making the patch. | |
172 | ||
173 | 10. Made restore understand FreeBSD UFS2 tapes. Thanks to | |
174 | David <vrtin@users.sourceforge.net> for submitting the bug | |
175 | and providing a test case. | |
176 | ||
177 | 11. Made dump work with an arbitrary integer level (no more 10 | |
178 | levels only limitation). Thanks to Matthew | |
179 | <msvincen@midway.uchicago.edu> for the patch. | |
180 | ||
181 | Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003) | |
182 | ======================================================================= | |
183 | ||
184 | 1. Added a note in the dump man page saying that the default | |
185 | blocksize can be 32 if -d is used with a high density argument. | |
186 | Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr> | |
187 | for the patch. | |
188 | ||
189 | 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS, | |
190 | LDFLAGS environment variables. Thanks to Arcady Genkin | |
191 | <antipode@users.sourceforge.net> for reporting the bug. | |
192 | ||
193 | 3. Made -e/-E options of dump accept an unlimited number of inodes | |
194 | to be excluded, rather than a hardcoded maximum. Thanks to | |
195 | Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch. | |
196 | ||
197 | 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE | |
198 | and -D_USE_BSD_SIGNAL defines in configure in order to solve | |
199 | 64bit build problems because quad_t is redifined with a | |
200 | different signature. Thanks to Mike Harris <mharris@redhat.com> | |
201 | for reporting this bug. | |
202 | ||
203 | 5. Made restore build on Solaris, making possible to | |
204 | restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke | |
205 | <uwe@ugsoft.de> for the patch. | |
206 | ||
207 | 6. Made an extension in the dump tape format capable of saving | |
208 | MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de> | |
209 | wrote the extension and contributed the restore code back | |
210 | into this codebase. The same extension mechanism will be | |
211 | used in the future to save ACLs... | |
212 | ||
213 | 7. Made rmt work correctly with regard to QFA and local/remote | |
214 | files and tapes. The remote access will however work only | |
215 | when the dump provided rmt version is used. If you want to | |
216 | use another rmt server, please do not use the QFA feature. | |
217 | Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch. | |
218 | ||
219 | Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003) | |
220 | ==================================================================== | |
221 | ||
222 | 1. Fixed the INSTALL file to reflect the actual install paths. | |
223 | Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for | |
224 | reporting the bug. | |
225 | ||
226 | 2. Fixed the configure script to only check for headers presence | |
227 | instead of trying to compile them. This should fix issues | |
228 | with old build environments. Thanks to Kari Lempiainen | |
229 | <kari@funky.pp.fi> for reporting the bug. | |
230 | ||
231 | 3. Fixed restore to correctly ignore sockets when comparing | |
232 | a dump (as socket cannot be properly restored anyway). Thanks | |
233 | to Gunther Reiszig <gunther@mit.edu> for reporting the bug. | |
234 | ||
235 | 4. Fixed restore to correctly access the archive file (-A argument) | |
236 | even when using a remote tape. Thanks to Fabrice Bellet | |
237 | <fabrice@bellet.info> for reporting the bug. | |
238 | ||
239 | 5. Fixed (again) handling of long (largefile) seeks in rmt. | |
240 | Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting | |
241 | the bug. | |
242 | ||
243 | 6. Fixed restore corner case when dealing with large block sizes | |
244 | dump is able to write now (-b 1024). Thanks to Fabrice Bellet | |
245 | <fabrice@bellet.info> for reporting the bug. | |
246 | ||
247 | 7. Fixed a bug preventing dump to access a filesystem having | |
248 | a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch> | |
249 | for reporting the bug. | |
250 | ||
251 | 8. Made dump store dump dates using explicit timezones, fixing a | |
252 | problem with incremental dumps if the timezone is modified | |
253 | between the dumps. Thanks to Philippe Troin <phil@fifi.org> for | |
254 | the bug report and the patch. | |
255 | ||
256 | 9. Fixed a bug encountered when dumping individual files (not full | |
257 | filesystems or directories) and dangling symbolic links happen | |
258 | to be in the list of files. For as far as dump is concerned, | |
259 | dangling symbolic links are allowed, and are dumped as is. | |
260 | Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the | |
261 | bug and providing the fix. | |
262 | ||
263 | 10. Fixed open and creation modes and permissions for QFA and | |
264 | table-of-contents files in dump and restore. Thanks to | |
265 | Philippe Troin <phil@fifi.org> for the patch. | |
266 | ||
267 | 11. Fixed the archive file descriptor handling enabling it to be 0. | |
268 | This can happen in some cases when shell redirections are used. | |
269 | Thanks to Philippe Troin <phil@fifi.org> for the patch. | |
270 | ||
271 | 12. Delayed the opening of archive file until after suid had been | |
272 | dropped (fixing a possible security issue if dump is suid). | |
273 | Thanks to Philippe Troin <phil@fifi.org> for the patch. | |
274 | ||
275 | 13. Fixed the 'S' command handling in the rmt client part. | |
276 | Thanks to Philippe Troin <phil@fifi.org> for the patch. | |
277 | ||
278 | 14. Modified the end-of-tape script handling to print out statistics | |
279 | (and stop the timer) before launching the eot script. Also, the eot | |
280 | script does not get run anymore when using -M (which makes sense) or | |
281 | when multiple tapes are listed on the command line | |
282 | (-f tape0,tape1,tapen) (which also makes sense). | |
283 | Thanks to Philippe Troin <phil@fifi.org> for the patch. | |
284 | ||
285 | 15. Relicensed dump/restore under the 'revised' BSD license, as per | |
286 | ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change. | |
287 | ||
288 | 16. Added LZO compression to dump. This new compression method has | |
289 | the advantage of being super fast, thus not killing tape streaming | |
290 | on slow machines. Thanks to Helmut Jarausch | |
291 | <jarausch@igpm.rwth-aachen.de> for the patch and to | |
292 | Markus Oberhumer <markus@oberhumer.com> for giving special permission | |
293 | to include his miniLZO project (GPL licensed) in dump/restore. | |
294 | ||
295 | 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia | |
296 | <ant@notatla.demon.co.uk> for reporting the bugs. | |
297 | ||
298 | 18. Added a special rmt version which can do encryption when writing | |
299 | to tape. Read examples/encrypted_rmt/README for details on | |
300 | how to enable and configure it. Thanks to Ken Lalonde | |
301 | <ken@globalremit.com> for the patch. | |
302 | ||
303 | 19. Made dump work with 2.5 kernel end of tape early warning semantics. | |
304 | Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch. | |
305 | ||
306 | 20. Fixed a bug which caused dump -w|-W not to work anymore, because | |
307 | the fs_freq and fs_passno fields in /etc/mtab are always set | |
308 | to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for | |
309 | reporting the bug. | |
310 | ||
311 | Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003) | |
312 | ======================================================================= | |
313 | ||
314 | 1. Added a note in the restore man page clarifying the question | |
315 | 'set the permissions on the current directory ?' asked by | |
316 | restore at the end of treatment in -i and -x modes. | |
317 | ||
318 | 2. Fixed the endianess issues when reading compressed tapes. | |
319 | Thanks to Dark Force <daq4th@users.sourceforge.net> for | |
320 | reporting this bug and providing test cases. | |
321 | ||
322 | 3. Fixed the "ACL won't be dumped" warning message (which showed | |
323 | an extra, unrelated error message). Thanks to Dragan Krnic | |
324 | <dkrnic@lycos.com> for reporting this bug. | |
325 | ||
326 | 4. Made dump look first into /etc/mtab, then into /etc/fstab | |
327 | when searching for filesystem paths. Also fixed some problems | |
328 | caused by binding mounts or multiple block device mounts. | |
329 | Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell | |
330 | <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>, | |
331 | Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086 | |
332 | and #160305, Sourceforge bugs #618699 and #679832). | |
333 | ||
334 | 5. Made dump's -I option accept the value '0' meaning all the | |
335 | read errors will be ignored. This can be useful when running | |
336 | dump from unattended sessions (like cron jobs). Thanks to | |
337 | John I Wang <jiwang@users.sourceforge.net> for the suggestion. | |
338 | ||
339 | 6. Fixed the output of dump to indicate 'blocks' instead of | |
340 | 'tape blocks' in the various messages (blocks are always | |
341 | 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and | |
342 | made it clearly print the current blocksize at the start of | |
343 | a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for | |
344 | the suggestions. | |
345 | ||
346 | 7. Made rmt understand long (largefiles) seeks. | |
347 | ||
348 | 8. Fixed build with very old versions of libext2fs, where | |
349 | EXT2_FT_* constants were undefined. | |
350 | ||
351 | 9. Made dump accept the dumpdates path on the command line | |
352 | (-D file option) instead of using only the hardcoded one. | |
353 | Thanks to Piete Brooks <pb22@users.sourceforge.net> for the | |
354 | suggestion. | |
355 | ||
356 | 10. Enabled rmt, LFS, readline, QFA options by default in | |
357 | ./configure. Updated the configure process (new versions | |
358 | of config.guess, config.sub etc). | |
359 | ||
360 | Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002) | |
361 | ======================================================================= | |
362 | ||
363 | 1. Changed dump to use fcntl(F_SETLK) style locking instead | |
364 | of flock() when locking the dumpdates file. With the old | |
365 | locking scheme, a local user having read rights on the | |
366 | dumpdates file could be able to do a Denial of Service attack | |
367 | on dump. In order to lock the dumpdates file with the new | |
368 | scheme, the user would need to have write access on the file. | |
369 | Thanks to Richard Johnson <Richard.Johnson3@ey.com> for | |
370 | reporting the bug (originally a bugtraq post). | |
371 | ||
372 | 2. Fixed interactive 'ls' which caused spurious errors warnings | |
373 | about 'undefined filetypes' detected. Thanks to Jorgen Ostling | |
374 | <jorgen_ostling@users.sourceforge.net> for reporting this | |
375 | bug. | |
376 | ||
377 | 3. Fixed dump's estimate when dealing with sparse inodes. | |
378 | ||
379 | 4. Modified dump to allow setting a blocksize bigger than 32kB | |
380 | (raised the limit to 1024kB), because newer hardware needs | |
381 | this for proper operation. Thanks to Dirk Traenapp | |
382 | <dtraenapp@users.sourceforge.net> for reporting this. | |
383 | ||
384 | 5. Fixed a bug causing Dump to stop and report an error if an | |
385 | inode number in the exclude file was followed by some amount | |
386 | of whitespace. Thanks to Jeffrey Sofferin | |
387 | <sofferin@users.sourceforge.net> for reporting this bug. | |
388 | ||
389 | 6. Fixed a bug which caused restore, in some particular cases, | |
390 | to ask some 'scary' questions and leave a bunch of RSTTMP | |
391 | directories behind when restoring incremental tapes. Thanks | |
392 | to Philippe Troin <phil@fifi.org> for reporting this bug and | |
393 | providing the test cases. | |
394 | ||
395 | 7. Changed the wording when inodes are excluded from dump: | |
396 | replaced 'Added inode 7 to exclude list' with | |
397 | 'Excluding inode 7 (resize inode) from dump', as suggested | |
398 | by Elliott Mitchell <ehem@m5p.com> in a Debian bug report. | |
399 | ||
400 | Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002) | |
401 | =================================================================== | |
402 | ||
403 | 1. Fixed rmt open flags transmission (GNU's symbolic syntax over | |
404 | rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi | |
405 | <eros@lamel.bo.cnr.it> for reporting the bug. | |
406 | ||
407 | Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002) | |
408 | =================================================================== | |
409 | ||
410 | 1. Made dump print out the ext2 logical block number in case of a read | |
411 | error, which can be given as an argument to debugfs' ncheck command, | |
412 | in order to find out the affected inode. Added note about this | |
413 | usage in dump's man page. | |
414 | ||
415 | 2. Fixed a problem in restore when reading tapes written on big | |
416 | endian machines with very old versions of dump. The patch was | |
417 | contributed by George Helffrich <george@geology.bristol.ac.uk>. | |
418 | ||
419 | 3. Fixed the tape length calculation when using large tapes | |
420 | and compression. Thanks to Georg Lippold | |
421 | <g_lippold@sourceforge.net> for reporting the bug. | |
422 | ||
423 | 4. Added a new set of examples in dump_on_cd_2 directory, based | |
424 | on dump_on_cd examples but somewhat enhanced, supporting DVD | |
425 | media, and localized in english and german. Thanks to | |
426 | Georg Lippold <g_lippold@sourceforge.net> for the new scripts. | |

428 | 5. Made dump save 32 bit UID/GID. Internally, this was achieved | |
429 | by switching from the old BSD inode format to the new BSD | |
430 | inode format, which means that the tape format was changed. | |
431 | However, since all restore versions out there should | |
432 | transparently support both inode formats, the change should | |
433 | have no side effects. Thanks to John Yu <jky@cs.bu.edu> for | |
434 | reporting the bug. | |

436 | 6. Fixed a lot of warnings in the code shown when compiling | |
437 | with 'gcc -W'. Thanks to Matthias Andree | |
438 | <matthias.andree@stud.uni-dortmund.de> for reporting this. | |
439 | ||
440 | 7. Fixed a small markup bug in the dump man page. Thanks to | |
441 | Eric S. Raymond <esr@minx.thyrsus.com> for submitting the | |
442 | patch. | |
443 | ||
444 | 8. Rewrote entirely the man pages using the tmac.an macro | |
445 | package (Linux man page format) instead of the original BSD | |
446 | format. They should be now cleaner and easier to modify. | |
447 | ||
448 | Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002) | |

451 | 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from | |
452 | non Linux clients were misinterpreted. The description of the problem | |
453 | (incompatible numbering in Linux mtio opcodes) is documented at | |
454 | ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to | |
