3 Changes between versions 0.4b42 and 0.4b43 (released ?????????????)
4 ===================================================================
5
6 1. Fix a bug in dump making impossible to handle large toc files
7 (> 2 GB). Thanks to X DUGi <xdugi@users.sourceforge.net> for
8 reporting the bug (Sourceforge bug #2820629)
9
10 2. Fix 'restore -x' in multi-volume mode, which caused files being
11 spanned on the first and second volumes to be incorrectly extracted.
12 Thanks to Adam Tkac <atkac@redhat.com> for reporting the bug.
13 (there may be several bug reports about this issue, including
14 Sourceforge bug #2117008, RedHat bugs #232415 and #444958).
15
16 3. Remove -lselinux -lsepol from the standard libraries list,
17 they shouldn't be needed if selinux is not enabled in dump
18 (this also fixes a build failure when selinux libraries are
19 not installed).
20
21 4. Fix restoration of extended attributes of fifos and device nodes.
22 Thanks to Igor Zhbanov <izh1979@gmail.com> for the bug report.
23
24 5. Don't attempt to set extended attributes on files that were not
25 extracted in 'restore -N' mode. Thanks to Jan Görig
26 <jgorig@users.sourceforge.net> for the patch.
27
28 6. Make the dump man page explicit about ext4 support.
29
30 7. Fix a bug in dump which caused EA entries to be unrecognizable by
31 restore in some corner cases. Add a workaround to restore making
32 it able to properly deal with those corrupted EA entries. Thanks
33 to John Austin <jaustin1@users.sourceforge.net> for reporting
34 the bug.
35
36 8. Fix some issues when restoring a dump which was generated using
37 exclusion patterns (either via -e or via the nodump attribute)
38 (see the Debian bug #574667 for details. Thanks to Frédéric
39 Brière <fbriere@fbriere.net> for the bug report and the associated
40 patch.
41
42 9. Fix progress/estimated blocks display in dump when doing really
43 huge backups. Thanks to Steve Bonds <sbonds@users.sourceforge.net>
44 for the bug report and tests. (Sourceforge bug #2987758)
45
46 Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009)
47 ===================================================================
48
49 1. Fix printout of the 'Connection to' message in dump/restore.
50 Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
51 bug report and its fix.
52
53 2. Fix dump -w/-W output for filesystems having the last backup
54 level equal to 0. Thanks to Pascal Bouchareine
55 <kalou@users.sourceforge.net> for reporting the bug.
56
57 3. Enable restore to handle restoring onto a different SELinux
58 policy from the dump. Thanks to Tony Nelson
59 <tony_nelson@users.sourceforge.net> for the patch.
60 (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845
61 for details)
62
63 4. Fix EA set failures when restoring immutable files. Thanks
64 to Andrew Kroeger for the patch.
65
66 5. Fix "mode file too large" errors when restoring huge backups.
67 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
68 report.
69
70 6. Add the ability to link against libtinfo library if present,
71 instead of libtermcap or libncurses libraries. Thanks to
72 Adam Tkac <atkac@redhat.com> for the patch.
73
74 7. When comparing a backup, do not consider to be an error the fact
75 that we encounter files created while dump was in progress.
76 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
77 report.
78
79 8. Force '-a' to be the default value when running 'restore -C'.
80 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
81 report.
82
83 9. Many improvements to the 'cron_dump_to_disk' example.
84 Thanks to Aaron S. Hawley <ashawley@users.sourceforge.net> for
85 the patch.
86
87 10. Fix the QFA generation when extended attributes are backuped
88 along with the inodes. Prior to this fix, the entries for
89 some inodes may get corrupted (duplicated entries or incorrect
90 ones), making the QFA file unusable for repositionning in
91 restore. Many thanks to Kenneth Porter <shiva@sewingwitch.com>
92 for the bug report and the testing of the fix.
93
94 11. Fix EA restoration in debug mode (Sourceforge bug #1986216).
95
96 12. Stefan Auracher <star7@onlinehome.de> noticed that the Tower
97 of Hanoi backup strategy documented in the man page wasn't
98 actually based on the Tower of Hanoi algorithm. The man page
99 was updated accordingly.
100
101 13. Fix missing level information from dump output when using
102 the default level (RedHat bug #493635). Thanks to Adam Tkac
103 <atkac@redhat.com> for the patch.
104
105 14. Fix the dump man page to reflect the fact that the default
106 dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac
107 <atkac@redhat.com> for the patch.
108
109 15. Fixed a few spelling errors in the man pages (RedHat bug #489853).
110 Thanks to Adam Tkac <atkac@redhat.com> for the patch.
111
112 16. Fixed restore man page and program usage which incorrectly stated
113 that -P and -A were both allowed in the same invocation (RedHat
114 bug #490627). Thanks to Adam Tkac <atkac@redhat.com> for the patch.
115
116 17. Use sys_clone under Linux to share I/O contexts between dump
117 processes, thus drastically increasing the performance of dump
118 under CFQ (which is the default I/O scheduler used in a number of
119 distributions). Thanks to Jeff Moyer <jmoyer@redhat.com> for the
120 patch.
121
122 18. Add (preliminary) ext4 support - thanks to libext2fs which does
123 all the job for us. Thanks to Gertjan van Wingerde
124 <gwingerde@gmail.com> for the patch.
125
126 Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
127 =====================================================================
128
129 1. Fix restore of dumped Access Control Lists. The previous
130 code for EA works fine, but ACLs needed conversion from the
131 ext2/3 disk format to posix_acl format before restoring.
132
133 2. Fix some issues with restoration of EA on big endian
134 platforms.
135
136 3. Fix restore when the symtab is over 2GB in size.
137
138 4. Made the directory hash indexing an optional feature,
139 accessible by the '-H' option of restore, and disable it
140 by default.
141
142 5. Fixed dump to not include extended attributes information
143 in the toc (archive) file which confused restore -t.
144
145 Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
146 =================================================================
147
148 1. Changed restore to emit warnings (instead of emitting a fatal
149 error) if a file (or a directory) is unavailable for a
150 comparision (if the user doesn't have the necessary permissions
151 to access it for example). Thanks to Kenneth Porter
152 <shiva@sewingwitch.com> for the bug report.
153
154 2. Re-done the 'do not save directory entries to non-dumped inodes
155 (excluded from dump)' feature. The previous implementation
156 worked well for excluded directories but not for regular files.
157 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
158 report.
159
160 3. Fixed a bug in dump where the tape size was miscalculated when
161 the user used -d/-s to specify the tape characteristics. Thanks
162 to Philip Goisman <goisman@physics.arizona.edu> for reporting
163 the bug.
164
165 4. Fixed another bug introduced in restore with the hashtree
166 implementation. This one caused restore to stop saying
167 "removenode: non-empty directory" in some cases.
168
169 5. Added support for dumping and restoring ext2/3 extended
170 attributes (EA), like the access control lists (ACL) or
171 the security labels used by SELinux.
172
173 Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
174 ======================================================================
175
176 1. The newly added dump_on_cd_3 example was buggy, replace it
177 with an updated version from Andrew Basterfield
178 <bob@cemetery.homeunix.org>.
179
180 2. Made restore to chdir() back into the initial directory when
181 dumping core while aborting a comparision operation. The
182 previous behaviour was to write the corefile at the root of
183 the directory being compared, which could very well be
184 read only and preventing the corefile generation. Thanks
185 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
186
187 3. Silenced the failure to call fgetflags() when comparing an
188 entry which has no ext2 attributes (as in lsattr()).
189
190 4. Fix a brown paper bug in restore -C which broke restore and
191 caused modifications on the filesystem being compared
192 (directories containing a file with the same name as the
193 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
194 <shiva@sewingwitch.com> for finding the bug and helping me
195 reproduce it.
196
197 5. Made restore -C force the -N flag (no writing allowed on
198 the disk) in order to prevent more bugs like the above one.
199
200 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
201 =====================================================================
202
203 1. Fix a couple of troff syntax bugs in the man pages.
204 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
205
206 2. Made restore use either libncurses or libtermcap, depending
207 on which one is available at configure time.
208
209 3. Fixed restore negative size display bug when comparing a
210 dump containing files over 2GB. Thanks to Steve Bonds
211 <sbonds@users.sourceforge.net> for the bug report.
212
213 4. Do not save directory entries to non-dumped inodes
214 (excluded from dump). This will eliminate the 'missing
215 file' warnings when doing 'restore -C'.
216
217 5. Fix dump crash when backuping a huge (2TB) filesystem,
218 due to a bogus calculation on the inode map size.
219 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
220 submitting the bug and testing the fix.
221
222 6. Fix a problem in restore where the final \0 in the symbolic
223 link names could have been lost, generating corrupt filenames.
224 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
225 bug.
226
227 7. Implemented a hash list for the directory names in restore.
228 The linear list used before caused problems in interactive
229 restores when dealing with directories having thousands of
230 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
231 for reporting the bug.
232
233 8. Improved restore -C, this time including the directory
234 attributes into the comparision.
235
236 9. Made restore understand tapes containing EA/ACLs (which will
237 be dumped by the next version of dump). In this version
238 extended attributes on the tape are ignored, for full EA/ACL
239 support wait for the next version or try the experimental EA
240 patch.
241
242 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
243 ==================================================================
244
245 1. Added the --enable-staticz configure option which enables
246 dump and restore to be linked with static versions of
247 libz and libbz2 (and dynamic versions of all other libraries).
248 This will make Debian users happy, because libz and libbz2
249 were the only needed libraries living in /usr, all the
250 others live in /lib. In case of system emergency, it is
251 better not to have to rely on an extra filesystem.
252 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
253
254 2. Fix compilation on (at least the Linux Debian port to) AMD64.
255 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
256 that are also defined by <linux/types.h> (<asm/types.h>) and
257 they conflict).
258
259 3. Make dump's reading of the dumpdates file a bit more robust,
260 preventing dump from crashing when the dumpdates file has
261 been modified by hand.
262
263 4. Fixed some offset calculations in dump code which could
264 lead to "bread lseek errors" on large filesystems. Thanks
265 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
266 reporting this bug and debugging the issue.
267
268 5. Made dump use the blkid library when searching for devices
269 by label or uuid instead of dump's own routines.
270
271 6. Corrected a bug in dump where a wrong LABEL=... line in
272 /etc/fstab could prevent dump from dumping unrelated
273 filesystems. Thanks to Bruce Lowekamp
274 <lowekamp@users.sourceforge.net> for reporting the bug.
275
276 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
277 ====================================================================
278
279 1. Fixed dump compilation with old gcc versions. Thanks to
280 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
281
282 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
283 when compiling against a recent glibc version.
284
285 3. Fixed a bug in restore preventing the read of a dump tape
286 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
287 <phiggins@transzap.com> for reporting the bug and providing
288 the test case.
289
290 4. Changed dump to enable the creation of volumes of different
291 sizes in a single run (make -B accept a list of values).
292 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
293
294 5. Use the glibc provided minor() and major() macros instead
295 of our own bitmask implementation. This should be safe for
296 when the major/minor namespace will migrate to 32 bits.
297 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
298 the bug.
299
300 6. Made explicit in the dump man page that dump will not create
301 a remote file, it will only write to an already existing one.
302
303 7. Another try at making size estimates better again.
304
305 8. Put back the inconditional running of the end-of-tape
306 script which was changed in 0.434 to be run only when -M
307 or multiple -f were NOT specified. Some users rely on this
308 feature even when it is combined with -M/-f.
309
310 9. Fixed restore when restoring huge backups (where rstdir...
311 temporary files are over 2GB). Thanks to
312 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
313 debugging the issue and making the patch.
314
315 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
316 David <vrtin@users.sourceforge.net> for submitting the bug
317 and providing a test case.
318
319 11. Made dump work with an arbitrary integer level (no more 10
320 levels only limitation). Thanks to Matthew
321 <msvincen@midway.uchicago.edu> for the patch.
322
323 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
324 =======================================================================
325
326 1. Added a note in the dump man page saying that the default
327 blocksize can be 32 if -d is used with a high density argument.
328 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
329 for the patch.
330
331 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
332 LDFLAGS environment variables. Thanks to Arcady Genkin
333 <antipode@users.sourceforge.net> for reporting the bug.
334
335 3. Made -e/-E options of dump accept an unlimited number of inodes
336 to be excluded, rather than a hardcoded maximum. Thanks to
337 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
338
339 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
340 and -D_USE_BSD_SIGNAL defines in configure in order to solve
341 64bit build problems because quad_t is redifined with a
342 different signature. Thanks to Mike Harris <mharris@redhat.com>
343 for reporting this bug.
344
345 5. Made restore build on Solaris, making possible to
346 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
347 <uwe@ugsoft.de> for the patch.
348
349 6. Made an extension in the dump tape format capable of saving
350 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
351 wrote the extension and contributed the restore code back
352 into this codebase. The same extension mechanism will be
353 used in the future to save ACLs...
354
355 7. Made rmt work correctly with regard to QFA and local/remote
356 files and tapes. The remote access will however work only
357 when the dump provided rmt version is used. If you want to
358 use another rmt server, please do not use the QFA feature.
359 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
360
361 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
362 ====================================================================
363
364 1. Fixed the INSTALL file to reflect the actual install paths.
365 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
366 reporting the bug.
367
368 2. Fixed the configure script to only check for headers presence
369 instead of trying to compile them. This should fix issues
370 with old build environments. Thanks to Kari Lempiainen
371 <kari@funky.pp.fi> for reporting the bug.
372
373 3. Fixed restore to correctly ignore sockets when comparing
374 a dump (as socket cannot be properly restored anyway). Thanks
375 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
376
377 4. Fixed restore to correctly access the archive file (-A argument)
378 even when using a remote tape. Thanks to Fabrice Bellet
379 <fabrice@bellet.info> for reporting the bug.
380
381 5. Fixed (again) handling of long (largefile) seeks in rmt.
382 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
383 the bug.
384
385 6. Fixed restore corner case when dealing with large block sizes
386 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
387 <fabrice@bellet.info> for reporting the bug.
388
389 7. Fixed a bug preventing dump to access a filesystem having
390 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
391 for reporting the bug.
392
393 8. Made dump store dump dates using explicit timezones, fixing a
394 problem with incremental dumps if the timezone is modified
395 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
396 the bug report and the patch.
397
398 9. Fixed a bug encountered when dumping individual files (not full
399 filesystems or directories) and dangling symbolic links happen
400 to be in the list of files. For as far as dump is concerned,
401 dangling symbolic links are allowed, and are dumped as is.
402 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
403 bug and providing the fix.
404
405 10. Fixed open and creation modes and permissions for QFA and
406 table-of-contents files in dump and restore. Thanks to
407 Philippe Troin <phil@fifi.org> for the patch.
408
409 11. Fixed the archive file descriptor handling enabling it to be 0.
410 This can happen in some cases when shell redirections are used.
411 Thanks to Philippe Troin <phil@fifi.org> for the patch.
412
413 12. Delayed the opening of archive file until after suid had been
414 dropped (fixing a possible security issue if dump is suid).
415 Thanks to Philippe Troin <phil@fifi.org> for the patch.
416
417 13. Fixed the 'S' command handling in the rmt client part.
418 Thanks to Philippe Troin <phil@fifi.org> for the patch.
419
420 14. Modified the end-of-tape script handling to print out statistics
421 (and stop the timer) before launching the eot script. Also, the eot
422 script does not get run anymore when using -M (which makes sense) or
423 when multiple tapes are listed on the command line
424 (-f tape0,tape1,tapen) (which also makes sense).
425 Thanks to Philippe Troin <phil@fifi.org> for the patch.
426
427 15. Relicensed dump/restore under the 'revised' BSD license, as per
428 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
429
430 16. Added LZO compression to dump. This new compression method has
431 the advantage of being super fast, thus not killing tape streaming
432 on slow machines. Thanks to Helmut Jarausch
433 <jarausch@igpm.rwth-aachen.de> for the patch and to
434 Markus Oberhumer <markus@oberhumer.com> for giving special permission
435 to include his miniLZO project (GPL licensed) in dump/restore.
436
437 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
438 <ant@notatla.demon.co.uk> for reporting the bugs.
439
440 18. Added a special rmt version which can do encryption when writing
441 to tape. Read examples/encrypted_rmt/README for details on
442 how to enable and configure it. Thanks to Ken Lalonde
443 <ken@globalremit.com> for the patch.
444
445 19. Made dump work with 2.5 kernel end of tape early warning semantics.
446 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
447
448 20. Fixed a bug which caused dump -w|-W not to work anymore, because
449 the fs_freq and fs_passno fields in /etc/mtab are always set
450 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
451 reporting the bug.
452
453 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
454 =======================================================================
455
456 1. Added a note in the restore man page clarifying the question
457 'set the permissions on the current directory ?' asked by
458 restore at the end of treatment in -i and -x modes.
459
460 2. Fixed the endianess issues when reading compressed tapes.
461 Thanks to Dark Force <daq4th@users.sourceforge.net> for
462 reporting this bug and providing test cases.
463
464 3. Fixed the "ACL won't be dumped" warning message (which showed
465 an extra, unrelated error message). Thanks to Dragan Krnic
466 <dkrnic@lycos.com> for reporting this bug.
467
468 4. Made dump look first into /etc/mtab, then into /etc/fstab
469 when searching for filesystem paths. Also fixed some problems
470 caused by binding mounts or multiple block device mounts.
471 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
472 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
473 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
474 and #160305, Sourceforge bugs #618699 and #679832).
475
476 5. Made dump's -I option accept the value '0' meaning all the
477 read errors will be ignored. This can be useful when running
478 dump from unattended sessions (like cron jobs). Thanks to
479 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
480
481 6. Fixed the output of dump to indicate 'blocks' instead of
482 'tape blocks' in the various messages (blocks are always
483 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
484 made it clearly print the current blocksize at the start of
485 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
486 the suggestions.
487
488 7. Made rmt understand long (largefiles) seeks.
489
490 8. Fixed build with very old versions of libext2fs, where
491 EXT2_FT_* constants were undefined.
492
493 9. Made dump accept the dumpdates path on the command line
494 (-D file option) instead of using only the hardcoded one.
495 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
496 suggestion.
497
498 10. Enabled rmt, LFS, readline, QFA options by default in
499 ./configure. Updated the configure process (new versions
500 of config.guess, config.sub etc).
501
502 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
503 =======================================================================
504
505 1. Changed dump to use fcntl(F_SETLK) style locking instead
506 of flock() when locking the dumpdates file. With the old
507 locking scheme, a local user having read rights on the
508 dumpdates file could be able to do a Denial of Service attack
509 on dump. In order to lock the dumpdates file with the new
510 scheme, the user would need to have write access on the file.
511 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
512 reporting the bug (originally a bugtraq post).
513
514 2. Fixed interactive 'ls' which caused spurious errors warnings
515 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
516 <jorgen_ostling@users.sourceforge.net> for reporting this
517 bug.
518
519 3. Fixed dump's estimate when dealing with sparse inodes.
520
521 4. Modified dump to allow setting a blocksize bigger than 32kB
522 (raised the limit to 1024kB), because newer hardware needs
523 this for proper operation. Thanks to Dirk Traenapp
524 <dtraenapp@users.sourceforge.net> for reporting this.
525
526 5. Fixed a bug causing Dump to stop and report an error if an
527 inode number in the exclude file was followed by some amount
528 of whitespace. Thanks to Jeffrey Sofferin
529 <sofferin@users.sourceforge.net> for reporting this bug.
530
531 6. Fixed a bug which caused restore, in some particular cases,
532 to ask some 'scary' questions and leave a bunch of RSTTMP
533 directories behind when restoring incremental tapes. Thanks
534 to Philippe Troin <phil@fifi.org> for reporting this bug and
535 providing the test cases.
536
537 7. Changed the wording when inodes are excluded from dump:
538 replaced 'Added inode 7 to exclude list' with
539 'Excluding inode 7 (resize inode) from dump', as suggested
540 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
541
542 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
543 ===================================================================
544
545 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
546 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
547 <eros@lamel.bo.cnr.it> for reporting the bug.
548
549 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
550 ===================================================================
551
552 1. Made dump print out the ext2 logical block number in case of a read
553 error, which can be given as an argument to debugfs' ncheck command,
554 in order to find out the affected inode. Added note about this
555 usage in dump's man page.
556
557 2. Fixed a problem in restore when reading tapes written on big
558 endian machines with very old versions of dump. The patch was
559 contributed by George Helffrich <george@geology.bristol.ac.uk>.
560
561 3. Fixed the tape length calculation when using large tapes
562 and compression. Thanks to Georg Lippold
563 <g_lippold@sourceforge.net> for reporting the bug.
564
565 4. Added a new set of examples in dump_on_cd_2 directory, based
566 on dump_on_cd examples but somewhat enhanced, supporting DVD
567 media, and localized in english and german. Thanks to
568 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
569
570 5. Made dump save 32 bit UID/GID. Internally, this was achieved
571 by switching from the old BSD inode format to the new BSD
572 inode format, which means that the tape format was changed.
573 However, since all restore versions out there should
574 transparently support both inode formats, the change should
575 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
576 reporting the bug.
577
578 6. Fixed a lot of warnings in the code shown when compiling
579 with 'gcc -W'. Thanks to Matthias Andree
580 <matthias.andree@stud.uni-dortmund.de> for reporting this.
581
582 7. Fixed a small markup bug in the dump man page. Thanks to
583 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
584 patch.
585
586 8. Rewrote entirely the man pages using the tmac.an macro
587 package (Linux man page format) instead of the original BSD
588 format. They should be now cleaner and easier to modify.
589
590 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
591 ==================================================================
592
593 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
594 non Linux clients were misinterpreted. The description of the problem
595 (incompatible numbering in Linux mtio opcodes) is documented at
596 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
597 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
598 providing an excellent, cross-platform replacement for rmt in his
599 star package.
600
601 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
602 which caused restore to fail when the inode maps were not entirely
603 contained on the first volume (when using really small volumes or
604 when dumping a huge number of inodes).
605
606 3. Fixed a problem in dump, where files in subdirectories of directories
607 that have the nodump flag set (or being excluded with -e/-E) were
608 sometimes incorrectly dumped (instead of being excluded). The original
609 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
610 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
611 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
612 help testing the patch.
613
614 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
615 which makes one able to pipe the output of dump, by the net, to
616 a remote CD-burner server.
617
618 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
619 and use GNU's symbolic syntax over rmt instead of numerical values
620 to assure multiple platform compatibility.
621
622 6. Documented the -d option in restore.
623
624 7. Added a -v (verbose) mode to dump. For now it just prints the number
625 of the inode being dumped, but this could evolve in future versions
626 to include interesting debugging output.
627
628 8. Added a -o flag to restore, which automatically restores the current
629 directory permissions in -i or -x mode, without asking the operator
630 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
631 and Peter Samuel <peters@e-smith.com>.
632
633 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
634 ====================================================================
635
636 1. Fixed a bug in the QFA feature which could have caused
637 a bad tape positionning on restore (causing extra delays in
638 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
639
640 2. Added a small note in the dump man page specifying that
641 there should be no white space between the option letter and
642 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
643
644 3. Made restore work with older versions of the readline library,
645 by checking in configure for several extended symbols. Restore
646 can now be compiled with a readline as old as the 2.0 release
647 (though it may be a good idea to upgrade it to a more recent
648 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
649 reporting the build failures.
650
651 4. Fixed a performance problem with the QFA file creation in
652 dump, which made unnecessary seeks on the tape slowing down
653 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
654 reporting this issue.
655
656 5. Removed the inclusion of some kernel headers in the dump
657 source, which prevented the compile in some kernel/glibc
658 headers/architecture combination. Thanks to Bdale Garbee
659 <bdale@gag.com> for reporting the bug.
660
661 6. Added the appropriate error message when dump fails to
662 open the output file for writing. Thanks to Amith Varghese
663 <amithv@yahoo.com> for reporting this bug.
664
665 7. Made restore able to understand large Solaris ufsdump tapes
666 (containing inodes bigger than 4194304). Sun have introduced
667 an "extension" to the dump tape format when dealing with
668 those inodes, which was uncorrectly handled by Linux restore.
669 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
670 providing a test case.
671
672 8. Added the -m parameter to dump which optimises the output for
673 inodes having been changed but not modified since the last dump
674 ('changed' and 'modified' have the meaning defined in stat(2)).
675 For those inodes, dump will save only the metadata, instead of
676 saving the entire inode contents. Inodes which are either
677 directories or have been modified since the last dump are saved
678 in a regular way. Uses of this flag must be consistent, meaning
679 that either every dump in an incremental dump set have the flag,
680 or no one has it.
681
682 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
683 =======================================================================
684
685 1. Fixed behaviour of dump when exceeding resource limits
686 (SIGXFSZ treatment).
687
688 2. Added the -L flag to restore to allow the user to specify a
689 maximal allowed number of miscompares when using restore
690 with the -C option to check the backup.
691
692 3. Detailed the manual entry for the -N option of restore.
693
694 4. Added the -a flag to restore to make able doing unattended
695 restores in -i or -x mode (automatically walks through the
696 multiple dump volumes).
697
698 5. Extended the QFA mode to work with local files and/or
699 remote tapes and files. This way, restore can know in advance
700 the tape number and the offset for the inodes to extract and
701 can minimize the extraction time by seeking directly to the
702 good tape/offset.
703
704 6. Added the -A <archive> option to both dump and restore,
705 which makes dump to archive a dump table-of-contents in
706 the specified file to be used by restore to determine
707 whether a file is in the dump file that is being restored.
708 (the archive file syntax is also compatible with the
709 Solaris ufsdump generated one).
710
711 7. Small fix in restore making it able to read some (broken ?)
712 Solaris ufsdump tapes.
713
714 8. Fixed dump to correctly recognise the root filesystem when using
715 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
716 for reporting this bug.
717
718 9. Added the -P <file> option to restore to create a
719 Quick File Access file from an already made dump. Patch
720 contributed by Uwe Gohlke <uwe@ugsoft.de>.
721
722 10. Made restore compile and run on Solaris, making it a
723 possible replacement for the standard ufsrestore. Port was
724 contributed by Uwe Gohlke <uwe@ugsoft.de>.
725
726 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
727 =====================================================================
728
729 1. Added a set of backup scripts from Eugenio Diaz
730 <getnito@yahoo.com> in the examples section. It features
731 automatic (cron based) full and incremental dumping of
732 several filesystems on a separate filesystem.
733
734 2. Fixed a off-by-one miscalculation which disabled dumping
735 a one letter subdirectory. Thanks to Chris Siebenmann
736 <cks@utcc.utoronto.ca> for reporting the bug.
737
738 3. Fixed several restore bugs occuring when trying to
739 restore some missing files on the tape. Thanks to Chris
740 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
741
742 4. Fixed --with-ldopts configure argument passing, installing from
743 a separate object directory, makefile cleanups contributed
744 by <splite@purdue.edu>.
745
746 5. Fix a bug which could caused, in some conditions, the highest
747 number inode of a filesystem, to not be dumped. Many thanks
748 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
749 chase this bug.
750
751 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
752 =======================================================================
753
754 1. Added a mini howto from Patrick Walsh in the examples
755 directory.
756
757 2. Minor man pages syntax corrections. Thanks to
758 Chris Danis <screechco@home.com> for reporting the bugs.
759
760 3. Added a script from David B. Peterson <dave@toppledwagon.com>
761 to the examples section. It features dumping several
762 filesystems to a remote tape drive upon ssh.
763
764 4. Added a patch provided by Richard Jones <rich@annexia.org>
765 which allows BRADEMAX (number of read errors tolerated by
766 dump) to be adjusted using the -I option.
767
768 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
769 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
770 patch.
771
772 6. Add the -l option to restore to specify if, when doing a
773 remote restore, the file used to access the backup is a
774 regular file (the defaults being a tape drive). Restore needs
775 to know this information when reading a remote compressed
776 dump. Previously, this information was autodetected, but
777 the autodetection code fails (with ioctl: Inappropriate ioctl
778 for device) when using a non Linux remote box. Thanks to
779 many users and especially to Eros Albertazzi
780 <eros@lamel.bo.cnr.it> for reporting this.
781
782 7. Found a workaroung for the dump deadlock problem (3 childs
783 stuck in pause(), father in read()). The workaround seems
784 to work for me and several beta-testers. If it doesn't work
785 for you, please report back.
786
787 8. Updated the RPM spec file (BuildPrereq, URL etc).
788
789 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
790 ========================================================================
791
792 1. Fixed the permissions of a newly created QFA file by dump.
793
794 2. Cleaned up the source of dump (the external variables
795 definition was a complete mess, making possible to have
796 objects overlap).
797
798 3. Fixed restore to use the full tape volume path when doing
799 a compare (since it changes the working directory to the
800 filesystem being compared in the process).
801
802 4. Added the -q option to dump which makes dump abort
803 whenever it needs operator attention. It should be
804 easier to use dump in scripts with this option.
805
806 5. Detect the use of incompatible options to dump and
807 refuse them (like -a and -B options together).
808
809 6. Added bzip2 compression to dump/restore (use option -j level
810 to select it). Note that you will need a restore version
811 >= 0.4b24 in order to restore a bzip2 compressed dump.
812 The same warning as for the zlib compression applies:
813 the tape format of a bzip2 dump is not compatible with the
814 original BSD tape format.
815
816 7. Fixed a overflow problem in dump corrupting the dump when
817 very large files were encountered. Thanks to Vladimir Nadvornik
818 for the bug report.
819
820 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
821 kernel buffer/page cache before starting the dump, helping
822 a bit those who use dump on mounted filesystems. Thanks to
823 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
824 for this suggestion.
825
826 9. Updated the RPM spec file following the RedHat changes
827 (dynamically linked binaries now in /usr/sbin etc).
828
829 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
830 which enables restore to recognise multi volume compressed dumps
831 done on CD. Included his scripts for dump (which pipe the dump
832 output directly into cdrecord) and restore. There is now
833 possible to to backups to CD on the fly!
834
835 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
836 ===================================================================
837
838 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
839 Marcus Meissner (Caldera International Security Dept.).
840
841 2. Implement the Sun rmt extended protocol. Patch submitted
842 by Ian Gordon <iangordon@users.sourceforge.net>.
843
844 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
845 the linux kernel header. This ensures that dump always has the
846 latest version of this file. Patch submitted by
847 Andreas Dilger <adilger@turbolinux.com>.
848
849 4. Report any filesystem present in either /etc/fstab with a
850 positive passno or /etc/dumpdates in dump -w output.
851 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
852
853 5. Fixed the looping problem in dump introduced in the
854 previous version.
855
856 6. Changed the -B option of dump to limit the size of
857 _compressed_ output per volume if compression is on.
858 Patch contributed by Helmut Jarausch
859 <jarausch@igpm.rwth-aachen.de>. Note however that, since
860 it is impossible to predict the size of the compressed
861 data before doing the compression, the -B limit is a bit
862 conservative.
863
864 7. Fixed a bug in reading the operator typed file/tape path for
865 the next volume in restore.
866
867 8. Implemented a "-F script" option to restore which permits the
868 user to specify a script which will be launched at the
869 beginning of each tape, useful for automatic programming of
870 tape changers for example. See the restore man page for the
871 script parameters and return codes.
872
873 9. Small fix for the QFA routines provided by Uwe Gohlke
874 <uwe@ugsoft.de>, and some recommendations for QFA uses in
875 the man pages.
876
877 10. Fixed the multivolume restoring where making a mistake
878 to the 'Mount next tape' prompt caused several blocks to
879 be lost.
880
881 11. Enhanced the -e option of dump to take as a parameter a
882 comma separated list of inode numbers.
883
884 12. Added the -E option to dump which specify a file containing
885 inode numbers to exclude from the dump.
886
887 13. Fixed the compressed multi-volume dump + restore.
888
889 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
890 ==================================================================
891
892 1. Made dump report the number of blocks dumped per volume.
893 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
894
895 2. Fix a bug in dump where waiting too much at the 'change volumes'
896 question caused the volume to be rewritten. Thanks to
897 Graham Reed <greed@users.sourceforge.net> for reporting the
898 bug and providing a patch.
899
900 3. Added a compression option to dump, contributed by Jerry
901 Peters <gapeters@worldnet.att.net>.
902
903 WARNING: the compression works only on files/pipes and
904 drives supporting variable block size.
905
906 WARNING2: tapes created using the compression feature are
907 incompatible with the standard dump tape format, and a
908 version of restore >= 0.4b22 will be needed for extraction.
909
910 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
911 architectures. Thanks to Paul Slootman <paul@debian.org> for
912 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
913 it upstream.
914
915 5. Many cleanups (CPP defines, const char warnings, check of
916 ext2fs COMPAT flags, time_t cleanups, added libext2 version
917 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
918
919 6. Made --prefix option work in configure. All the install path
920 are now based on the configure parameters.
921
922 7. Added the Quick File Access mode in dump/restore, contributed
923 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
924 a file tape position for each inode, and this file is used by
925 restore (if called with parameter Q and the filename)
926 to directly position the tape at the file restore is currently
927 working on. This saves hours when restoring single files from
928 large backups, saves the tapes and the drive's head. Use
929 --enable-qfa option of configure to compile in the QFA support.
930
931 8. Added the possibility to dump several files and directories
932 in a single invocation of dump. Thanks to Uwe Gohlke
933 <uwe@ugsoft.de> for implementing this option.
934
935 9. Fixed the dumping and restoring of files with holes
936 (files ending with holes didn't get dumped or restored
937 correctly).
938
939 10. Fixed a socket descriptor leak in dump, which leaved opened
940 3 file descriptors per dump process (and there is one dump
941 process per tape).
942
943 11. Fixed dump large file system support, by explicit use of
944 open64/lseek64/etc functions (explicit use needed because
945 e2fsprogs libraries don't behave well when compiled with
946 FILE_OFFSET_BITS=64).
947
948 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
949 ======================================================================
950
951 1. Fixed some bugs in the dump -w|-W logic introduced by
952 the previous version. Thanks to Andreas Dilger
953 <adilger@turbolinux.com> for his help on this one.
954
955 2. Fixed again a compilation problem when using old e2fs
956 headers (filesystem label related). Thanks to many users
957 who reported this stupid error.
958
959 3. Fixed a build problem on old lib5 based systems dealing with
960 _PATH_MNTTAB being undefined. Thanks to John Adams
961 <johna@onevista.com> for reporting the bug.
962
963 4. Improved the error detection in restore when creating
964 the temporary files in TMPDIR. Now restore will corectly
965 report a 'no space left on device' error instead of
966 strange errors which could imply an archive corruption.
967 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
968 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
969
970 5. Added the throughput information in dump's progression
971 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
972 for the patch.
973
974 6. Use libext2fs's inode scanning routines, which are particularly
975 robust when dealing with errors (especially when having some
976 bad blocks on the filesystem). Many thanks to Colin
977 <colin@horizon.com> for reporting the bug, investigating
978 the issues, finding a workaround, writing the patch and
979 fully testing it... (of course, if this patch will break
980 anything, he is to blame for :-)).
981
982 7. Made dump and restore LFS aware. Dump can dump a filesystem
983 containing large files, generate a large file on output and
984 restore can restore them. This feature is not enabled by
985 default, use --enable-largefile option of configure to enable
986 it (you need to have a LFS aware glibc though). Thanks to
987 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
988 and to Theodore T'so <tytso@valinux.com> for his always
989 useful thoughts.
990
991 8. Made dump ask upon a tape write error if it should rewrite
992 the current volume (assume this is a bad tape) or if it should
993 assume an end-of-tape condition (useful for tape drives which
994 behaves badly at the end of the tape). Thanks to Andreas
995 Dilger <adilger@turbolinux.com> for the suggestion.
996
997 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
998 =======================================================================
999
1000 1. Fixed a small compilation problem due to a change
1001 in the definintion of the struct sigaction in
1002 glibc 2.0 / libc5. Thanks to Gunther Schlegel
1003 <schlegel@riege.de> for reporting the bug and to
1004 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
1005 a fix.
1006
1007 2. Modified the label and uuid analysis in order to be
1008 self-contained (independant of kernel/libc headers). This
1009 should fix the compile with older kernel/libc headers and
1010 will preserve the functionality. Thanks to Bernhard Erdmann
1011 <bernhard.erdmann@gmx.de> for reporting the bug.
1012
1013 3. The 'exclude inode' option, if applied to a directory
1014 inode, excludes now correctly all the leaves of this
1015 directory. Thanks to John R. Dennison
1016 <gerdesas@users.sourceforge.net> for reporting the bug.
1017
1018 4. Fixed the '-e' option to disable the possibility
1019 to exclude the root inode (which causes the dumps to
1020 be unreadable by restore). Prevented array overflow
1021 when multiple -e options are used.
1022
1023 5. Fixed dump to correctly interpret a filesystem argument
1024 which is a mountpoint and it is not an absolute path
1025 (as specified in the fstab). Thanks to Bernhard R. Erdmann
1026 <be@berdmann.de> for reporting the bug.
1027
1028 6. Made dump able to backup files larger than 2 GB. Note that
1029 dump still doesn't cope with files larger than 4 GB.
1030
1031 7. Restore the real uid and gid before invoking an external
1032 RSH program (big hole when dump or restore is suid root!).
1033
1034 8. Get the values for the default tape device and the location
1035 of fstab file from the system headers. Thanks to
1036 Andreas Dilger <adilger@turbolinux.com> for the patch.
1037
1038 9. Made dump -w|-W report all recognized filesystems
1039 present in either /etc/fstab or /etc/dumpdates, and present
1040 the list in the same order as in fstab file. Thanks
1041 to Andreas Dilger <adilger@turbolinux.com> for the patch.
1042
1043 10. Made dump's -a (automatic end of tape detection) the
1044 default. Specifying one of -B, -c, -d or -s options will
1045 override the EOM detection. Thanks to Andreas Dilger
1046 <adilger@turbolinux.com> for the patch.
1047
1048 11. Save the ext2 filesystem label into the dump volume label.
1049 Specifying a volume label on the command line (-L option)
1050 will override this feature. Thanks to Andreas Dilger
1051 <adilger@turbolinux.com> for the patch.
1052
1053 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
1054 =====================================================================
1055
1056 1. Fixed the signal handling in dump (which I broke in 0.4b17)
1057 which was causing several strange dump failures (dump
1058 hanged or segmentation faults etc).
1059
1060 2. Specified the default blocksize in the dump man page.
1061
1062 3. Changed two info messages of restore to be written on stdout
1063 instead of stderr in order to leave stderr only for errors
1064 or warnings. Thanks to Stephen Atwell
1065 <satwell@urbana.css.mot.com> for the suggestion.
1066
1067 4. Corrected an off by one calculation which prevented
1068 dumping a directory having a 1 character name length.
1069 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
1070 for reporting the bug.
1071
1072 5. Reinforce dump in order to allow only level 0 and no
1073 -u option when dumping a subdirectory, and document
1074 this in the man page. Thanks to Bernhard Erdmann
1075 <bernhard.erdmann@gmx.de> for reporting the bug.
1076
1077 6. Fixed a small harmless bug in restore which caused
1078 in some conditions hard links to be restored several
1079 times (therefore generation some warning messages).
1080 Thanks to Kenneth Porter <shiva@well.com> for
1081 reporting the bug.
1082
1083 7. Updated the RPM spec file to the latest RedHat version,
1084 providing FHS packaging and other cosmetic changes.
1085 You will need RPM version >= 3.0.5 in order to build the RPM.
1086
1087 8. Updated the configure script to check for libtermcap
1088 before checking for libreadline, because we need this
1089 library in order to compile the readline support.
1090
1091 9. Made dump understand the LABEL= and UUID= notation
1092 both in /etc/fstab and on the command line. Note that
1093 you will need the /proc filesystem in order to use
1094 these notations. Thanks to Erik Troan <ewt@redhat.com>
1095 for providing the patch.
1096
1097 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
1098 ===================================================================
1099
1100 1. Fixed a potential buffer overflow in restore. Thanks
1101 to Stan Bubrouski <satan@fastdial.net> for reporting
1102 the bug.
1103
1104 2. Fixed a readline-related bug which prevented
1105 'cat DUMPFILE | restore -i -f -' from working. Thanks
1106 to Charles Karney <karney@users.sourceforge.net>
1107 for the bug report.
1108
1109 3. Changed a few "panic" into "exit", causing restore to
1110 be more stable against some attacks (like the last one
1111 reported on Bugtraq, although the last version of restore
1112 was not vulnerable - just dumped core). Thanks to
1113 Andreas Hasenack <andreas@conectiva.com.br> for reporting
1114 the bugs to me.
1115
1116 4. Removed the suid-root bit on dump and restore in the
1117 default build (and generated RPMs). It should be safer
1118 now. Users who need the suid-root capabilities in order
1119 to make network backups should read first the man page
1120 of dump and enable the suid bit manually.
1121
1122 5. Added -ltermcap to the compile parameters for restore
1123 when using readline support, in order to make the compile
1124 process work on some systems (SuSE ?). Thanks to
1125 Patrik Schindler <poc@pocnet.net> for reporting the bug.
1126
1127 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
1128 ====================================================================
1129
1130 1. The -F script is called now *only* at the end of a tape,
1131 not at the end of the dump. Thanks to Christian Haul
1132 <haul@informatik.tu-darmstadt.de> for the bug report.
1133
1134 Normally, the device name and the current volume number
1135 are passed on the command line of the script. However,
1136 if you want the old style script (with no arguments
1137 passed on the command line), you can enable it in
1138 configure with the --enable-oldstylefscript.
1139
1140 2. Use posix signal handling to preserve dump functionality
1141 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
1142 the patch.
1143
1144 3. Made the exit code of restore in case of a 'C'ompare
1145 command reflect the result of the compare. An exit status
1146 of 0 means the dump archive is correct, 1 means tape errors,
1147 2 means that some files were modified. Thanks to Kenneth Porter
1148 <shiva@well.com> for the suggestion.
1149
1150 4. Made (finally) quotes work in interactive restore.
1151
1152 5. Small fixes in order to allow dump to compile with a
1153 really old e2fsprogs version. Thanks to Ian Zimmerman
1154 <itz@speakeasy.org> for the bug report.
1155
1156 6. Add GNU readline capabilities to interactive restore.
1157 Use configure's --enable-readline flag to enable this feature.
1158 Thanks to Patrik Schindler <poc@pocnet.net> for the
1159 suggestion.
1160
1161 7. Do the compare on the fly in restore 'C' mode (this will
1162 allow not to exhaust the available /tmp space when
1163 ccmparing large files). Thanks to Kenneth Porter
1164 <shiva@well.com> for the suggestion.
1165
1166 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
1167 ====================================================================
1168
1169 1. Fixed some several duplicate 'DUMP: DUMP:' in the
1170 output of dump.
1171
1172 2. Corrected the estimation of blocks to dump. Note that
1173 this is still wrong for large directory inodes, due
1174 to the size of a BSD directory entry on the tape
1175 (estimation is based on the size of the ext2 directory,
1176 which is smaller because it doesn't contain the null
1177 character at the end).
1178
1179 3. Made dump report the total number of MB written to
1180 tape at the end of run. Thanks to W. Reilly Cooley
1181 <wcooley@nakedape.cc> for the patch.
1182
1183 4. Added the -X option to restore giving the possibility
1184 to read the names of the files to be extracted/listed
1185 from a text file (in addition of the command line).
1186 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
1187 patch.
1188
1189 5. Added the device name and the current volume number
1190 as arguments to the end of tape script (dump -F option).
1191
1192 6. Made the multi-volume dump work again (after having
1193 broken it in 0.4b15).
1194
1195 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1196 ===================================================================
1197
1198 1. Added a prompt command in interactive restore mode. Thanks
1199 to Andreas Dilger <adilger@home.com> for the patch.
1200
1201 2. Fixed a buffer overflow problem in dump (caused by
1202 not checking the size of the filesystem parameter).
1203 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1204 reporting this on Bugtraq (and to several dump users
1205 who forwarded me his mail).
1206
1207 3. Added the '-F script' option to dump in order to
1208 launch a script at the end of each tape (to be used
1209 with a tape changer, or to notify the sysadmin by
1210 pager etc.).
1211
1212 4. Fixed a bug in restore compare code caused by the changes
1213 I made in 0.4b14.
1214
1215 5. Fixed the treatment of options using the old BSD syntax
1216 in both dump and restore.
1217
1218 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1219 =======================================================================
1220
1221 1. Fixed a bug in dump which may have caused invalid deleted
1222 directories to be dumped out if they were deleted after the
1223 mapping pass. This could occure on active filesystem and lead
1224 to heap corruption (causing dump malfunction in many possible ways).
1225 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1226 bug and submitting the patch.
1227
1228 2. Fixed the handling of the filesystem parameter in dump. A
1229 '/mnt/disk' parameter caused the disk contents to be dumped,
1230 but a '/mnt/disk/' parameter caused the mountpoint directory
1231 to be dumped (generally an empty directory).
1232
1233 3. Improved the output of dump in order to tell which directory
1234 it is currently dumping (when dumping a subtree).
1235
1236 4. Added the '-e' exclude inode option to dump. Thanks to
1237 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1238
1239 5. Added a REPORTING-BUGS file in order to provide a guide
1240 on how to correctly report a bug in dump/restore.
1241
1242 6. Fixed a restore problem when restoring a hard link to an inode
1243 having the immutable or append-only attribute set. Thanks to
1244 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1245
1246 7. Fixed a compatibility problem between dumps made on little
1247 endian machines (the format was correct) and big endian
1248 machines (the format was incorrect). This fix break the
1249 compatibility with the older dumps made on big endian
1250 machines (sparc, m86k, ppc etc). For the first time in
1251 linux dump's history (I believe), the dumps made by *BSD,
1252 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1253 so interchangeable. Thanks to Rob Cermak
1254 <cermak@ahab.rutgers.edu> for submitting the bug and
1255 helping me test the fix.
1256
1257 8. Fixed the way dump reports the remaining percent/time, if
1258 the number of blocks actually dumped exceeds the estimated
1259 number of blocks. Thanks to Jean-Paul van der Jagt
1260 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1261
1262 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1263 ======================================================================
1264
1265 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1266 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1267
1268 2. Removed the requirement to build the RPM as root from the
1269 spec file. Thanks to Christian Weisgerber
1270 <naddy@mips.rhein-neckar.de> for submitting this.
1271
1272 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1273 causing dump to block when dumping really huge filesystems.
1274 Many thanks to Patrik Schindler <poc@pocnet.net> for
1275 helping me find this bug.
1276
1277 4. Fixed the treatment for an interrupt signal when dump access
1278 the remote tape through RSH. Thanks to Christian Weisgerber
1279 <naddy@mips.rhein-neckar.de> for providing the patch.
1280
1281 5. Fixed a bug which was causing dump/restore to display
1282 garbage characters instead of the remote host name.
1283
1284 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1285 =====================================================================
1286
1287 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1288 <kukuk@suse.de> for submitting the patch.
1289
1290 2. Fix for the exit code when using the size estimate option of
1291 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1292 submitting the patch.
1293
1294 3. Handle EINTR in atomical reads/writes in dump, which was causing
1295 dump to fail on some systems. Thanks to Eric Jergensen
1296 <eric@dvns.com> for reporting the bug and submitting the patch.
1297
1298 4. Handle more than 16 characters for the device names in dumpdates.
1299 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1300 tracking down the problem and proposing the solution.
1301
1302 5. Fixed a bug in dump which prevented the creation of the
1303 dumpdates file when doing a 0-level dump without already
1304 having a dumpdates file. Thanks to Patrik Schindler
1305 <poc@pocnet.net> for reporting the bug.
1306
1307 6. Changed the way dump 'S' flag reports the size estimate
1308 from number of blocks into bytes (making it compatible
1309 with the Solaris version, and simplifying things for
1310 amanda users). Thanks to Jason L Tibbitts III
1311 <tibbs@math.uh.edu> for reporting the bug.
1312
1313 7. Fixed a compatibility problem in linux/alpha dump tape format.
1314 Now the linux/alpha dump are (again) compatible with the
1315 other dump formats. But this breaks compatibility with
1316 older dumps made on alpha. Thanks to Mike Tibor
1317 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1318
1319 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1320 ======================================================================
1321
1322 1. Added a '--enable-kerberos' to configure.
1323
1324 2. Added a 'S' option to dump which determines the amount of space
1325 that is needed to perform the dump without actually doing it, similar
1326 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1327 <cermak@ahab.rutgers.edu>.
1328
1329 3. Added a 'M' multi-volume option to dump and restore which enables
1330 dumping to multiple files (useful when dumping to an ext2
1331 partition to make several dump files in order to bypass the 2GB
1332 file size limitation). The 'f' argument is treated as a prefix and
1333 the output files will be named <prefix>001, <prefix>002 etc. With
1334 the 'M' flag, restore automatically selects the right file without
1335 asking to enter a new tape each time.
1336
1337 4. Fixed a memory leak which was causing dump to grow very big
1338 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1339 Fearon <jasonf@netrider.org.au> for reporting the bug.
1340
1341 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1342 ======================================================================
1343
1344 1. Make configure test if the system glob routines support
1345 extended syntax (ALTDIRFUNC). If not, use the internal glob
1346 routines instead of system ones. Thanks to Bernhard Sadlowski
1347 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1348 and helping me resolve this and other minor libc5 compiling
1349 glitches.
1350
1351 2. Fix a problem when dumping a ext2fs with the 'filetype'
1352 feature enabled. Thanks to Patrick J. LoPresti
1353 <patl@cag.lcs.mit.edu> for reporting the bug and to
1354 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1355
1356 3. Made the nodump flag work on directories. A directory which
1357 has the nodump flag gets never dumped, regardless of its
1358 contents.
1359
1360 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1361 which allows dump on an active ext3 filesystem. However, this
1362 is a "quick and dirty" patch which enables backup of an ext3
1363 filesystem through the ext2 compatibility (by ignoring the
1364 NEEDS_RECOVERY bit). The journal file is not recognized and
1365 it is dumped (it should not).
1366
1367 5. Test the superblock compatibility flags when dumping, in order
1368 to be sure that we know how to deal with specific features.
1369
1370 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1371 ====================================================================
1372
1373 1. Use lchown instead of chown, fixing a possible security problem
1374 when restoring symlinks (a malicious user could use this
1375 to deliberately corrupt the ownership of important system files).
1376 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1377 this and providing the patch.
1378
1379 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1380 ====================================================================
1381
1382 1. Put dump sources under CVS, added Id tags in all files so
1383 one can use 'ident' on binary files.
1384
1385 2. Added the dump/restore version in the usage text so one can
1386 easily verify the version he is using.
1387
1388 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1389 a va_start/va_end problem on linux-ppc (always call va_start
1390 va_end in pairs each time we use a vararg function).
1391
1392 4. Added again the DT_* constants because old libc does not
1393 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1394 for submitting the bug report.
1395
1396 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1397 this should enable dumping big (huge) filesystems.
1398
1399 6. Added the RSH environment variable in order to be able to
1400 use a rsh replacement like ssh when doing remote backups (and
1401 bypass the security limitations of rcmd). Now you can do remote
1402 backups without being root (or making dump setuid root).
1403
1404 7. Modified again the way dumpdates works. For incremental dumps,
1405 we need to read dumpdates even if we are not using 'u' option.
1406 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1407 this should work.
1408
1409 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1410 ===================================================================
1411
1412 1. Removed the 'k' flag from the restore 'about' text if kerberos
1413 was not compiled in.
1414
1415 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1416 to them (fsetflags takes a char*, setflags an open fd!).
1417
1418 3. (f)setflags is called only if the flags aren't empty. If the
1419 file is a special file, a warning is printed, because changing
1420 flags implies opening the device. Normally, a special file
1421 should not have any flag... (Debian bug #29775, patch provided
1422 by Abhijit Dasgupta <abhijit@ans.net>).
1423
1424 4. Made possible to dump a file system not mentioned in /etc/fstab.
1425 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1426
1427 5. Changed the default behaviour to not create dumpdates
1428 unless 'u' option is specified. Removed the old "debian-patch"
1429 which provided the same thing. (Debian bug #38136, #33818).
1430
1431 6. Removed all those dump*announce, since they were getting old...
1432
1433 7. Added warning messages if dumpdates does not exist and
1434 when an inferior level dump does not exist (except for a level 0
1435 dump).
1436
1437 8. Debugged the glob calls in interactive mode: restore used a
1438 dirent struct which was different from the /usr/include/dirent.h
1439 one (this used to work, is it a glibc2 change?), so none of the
1440 compat glob (which used /usr/include/dirent.h) or the system glob
1441 worked. Restore use now the system dirent (and the system
1442 DT_* constants), which are compatible with BSD ones.
1443
1444 9. Added a configure flag (--with-dumpdatespath) to specify
1445 the location of dumpdates file. By default, it is
1446 /etc/dumpdates.
1447
1448 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1449 included the current date/version in man pages.
1450
1451 11. Corrected the estimation of remaining time when
1452 the operator doesn't change the tapes quickly enough. This
1453 was an old bug, I thought I corrected it, and discovered
1454 that in fact it was corrected in two different places, so
1455 the results canceled each other...
1456
1457 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1458 ===================================================================
1459
1460 1. Integrated multiple patches from RedHat, Debian and SuSE:
1461
1462 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1463 isn't specified.
1464 - several fixes in the man pages.
1465 - update the default tape device to /dev/st0.
1466 - many updates for Linux Alpha (byte ordering, size_t etc).
1467 - buffer overruns.
1468 - use environment variable for TMPDIR (instead of /tmp).
1469 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1470 - workaround egcs bug (RedHat bugs #4281 and #2989).
1471 - wire $(OPT) throughout Makefile's.
1472
1473 2. Upgrade the dump revision to 1, making possible to dump filesystems
1474 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1475
1476 3. Fix some compile warnings, prototype all functions.
1477
1478 4. Use glibc err/glob instead of internal compatibility
1479 routines (only if available).
1480
1481 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1482 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1483
1484 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1485 ======================================================================
1486
1487 1. Integrated the changes from FreeBSD-3.1-RELEASE
1488 (mostly bug fixes, buffer overruns, dump has now an "automatic
1489 tape length calculation" flag, dump/restore can use kerberos now
1490 (this is NOT tested), use environment variables for TAPE and
1491 RMT etc.).
1492
1493 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1494
1495 3. Corrected a bug in restore when using 'C' option with multi-volumes
1496 tapes (files splited accros two tapes give "size changed" errors
1497 when comparing).
1498
1499 4. Corrected the long standing bug when dumping multiple tapes.
1500 This works for me, needs further testing.
1501
1502 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1503 ====================================================================
1504
1505 1. Dump now runs correctly on kernels 2.1.x
1506 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1507
1508 Changes between versions 0.4b2 and 0.4b3
1509 ========================================
1510
1511 1. Use realpath() if available
1512
1513 2. Report statistics
1514
1515 Changes between versions 0.4b1 and 0.4b2
1516 ========================================
1517
1518 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1519 the patch)
1520
1521 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1522
1523 3. Fixed configure.in to correctly handle --enable-rmt
1524
1525 Changes between versions 0.3 and 0.4b1
1526 ======================================
1527
1528 1. Integrated the changes from 4.4BSD-Lite2
1529
1530 2. Integrated the patches from Debian and Red Hat
1531
1532 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1533
1534 4. Changed dump to use the Ext2fs library to get block addresses. This
1535 should solve the endianness problem on SparcLinux.
1536
1537 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1538 distribution's one) to use autoconf
1539
1540 6. Fixed a few minor bugs
1541
1542 Changes between versions 0.2e and 0.2f
1543 ======================================
1544
1545 1. Added the creation of named pipes (fifos) in restore.
1546
1547 2. Added the -N flag in the restore manual page.
1548
1549 3. Added the file kernel.patch which contains the llseek() optimization
1550 patch for 1.2.x kernels.
1551
1552 4. Fixed a bug in the restoration of symbolic links: owner and group were
1553 not restored.
1554
1555 5. Integrated some changes from FreeBSD 2.2.
1556
1557 6. Added a call to ftruncate() after restoring each file to restore
1558 correctly files ending by a hole.
1559
1560 Changes between versions 0.2d and 0.2e
1561 ======================================
1562
1563 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1564 with owner = root (0) and group = root/wheel/whatever (0).
1565
1566 Changes between versions 0.2c and 0.2d
1567 ======================================
1568
1569 1. Dump is now able to backup 2GB+ filesystems.
1570
1571 2. Dump and restore can now be linked as static binaries.
1572
1573 Changes between versions 0.2b and 0.2c
1574 ======================================
1575
1576 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1577
1578 Changes between versions 0.2a and 0.2b
1579 ======================================
1580
1581 1. Really fixed the bug that I should have corrected in 0.2a.
1582
1583 2. Enabled optimization again.
1584
1585 Changes between versions 0.2 and 0.2a
1586 =====================================
1587
1588 1. Disabled the optimization during compilation.
1589
1590 Changes between versions 0.1 and 0.2
1591 ====================================
1592
1593 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1594 the fs_type field (actually, I modified the file fstab.c to make it
1595 use the mntent functions).
1596
1597 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1598 made by dump should be readable by the BSD restore and backups made
1599 by the BSD dump should be readable by restore. Unfortunately, this
1600 means that the dump format has changed between version 0.1 and version
1601 0.2 :-(
1602
1603 3. Dump is now able to backup a subtree, it is no longer limited to whole
1604 filesystems like the BSD version.
1605
1606 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1607 than 2 GB.
1608
1609 Changes between versions 0.0 and 0.1
1610 ====================================
1611
1612 1. Now create links rdump and rrestore during the `make install' step.
1613
1614 2. Linux port specific bugs added to the manual pages
1615
1616 3. Incorrect estimation of the number of tapes blocks fixed when doing
1617 incremental backups.
1618
1619 4. Better ls-like format in restore in interactive mode.
