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