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