3 Changes between versions 0.4b36 and 0.4b37 (released ??????????????)
4 ====================================================================
6 1. Added the --enable-staticz configure option which enables
7 dump and restore to be linked with static versions of
8 libz and libbz2 (and dynamic versions of all other libraries).
9 This will make Debian users happy, because libz and libbz2
10 were the only needed libraries living in /usr, all the
11 others live in /lib. In case of system emergency, it is
12 better not to have to rely on an extra filesystem.
13 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
15 2. Fix compilation on (at least the Linux Debian port to) AMD64.
16 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
17 that are also defined by <linux/types.h> (<asm/types.h>) and
20 3. Make dump's reading of the dumpdates file a bit more robust,
21 preventing dump from crashing when the dumpdates file has
22 been modified by hand.
24 4. Fixed some offset calculations in dump code which could
25 lead to "bread lseek errors" on large filesystems. Thanks
26 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
27 reporting this bug and debugging the issue.
29 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
30 ====================================================================
32 1. Fixed dump compilation with old gcc versions. Thanks to
33 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
35 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
36 when compiling against a recent glibc version.
38 3. Fixed a bug in restore preventing the read of a dump tape
39 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
40 <phiggins@transzap.com> for reporting the bug and providing
43 4. Changed dump to enable the creation of volumes of different
44 sizes in a single run (make -B accept a list of values).
45 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
47 5. Use the glibc provided minor() and major() macros instead
48 of our own bitmask implementation. This should be safe for
49 when the major/minor namespace will migrate to 32 bits.
50 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
53 6. Made explicit in the dump man page that dump will not create
54 a remote file, it will only write to an already existing one.
56 7. Another try at making size estimates better again.
58 8. Put back the inconditional running of the end-of-tape
59 script which was changed in 0.434 to be run only when -M
60 or multiple -f were NOT specified. Some users rely on this
61 feature even when it is combined with -M/-f.
63 9. Fixed restore when restoring huge backups (where rstdir...
64 temporary files are over 2GB). Thanks to
65 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
66 debugging the issue and making the patch.
68 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
69 David <vrtin@users.sourceforge.net> for submitting the bug
70 and providing a test case.
72 11. Made dump work with an arbitrary integer level (no more 10
73 levels only limitation). Thanks to Matthew
74 <msvincen@midway.uchicago.edu> for the patch.
76 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
77 =======================================================================
79 1. Added a note in the dump man page saying that the default
80 blocksize can be 32 if -d is used with a high density argument.
81 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
84 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
85 LDFLAGS environment variables. Thanks to Arcady Genkin
86 <antipode@users.sourceforge.net> for reporting the bug.
88 3. Made -e/-E options of dump accept an unlimited number of inodes
89 to be excluded, rather than a hardcoded maximum. Thanks to
90 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
92 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
93 and -D_USE_BSD_SIGNAL defines in configure in order to solve
94 64bit build problems because quad_t is redifined with a
95 different signature. Thanks to Mike Harris <mharris@redhat.com>
96 for reporting this bug.
98 5. Made restore build on Solaris, making possible to
99 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
100 <uwe@ugsoft.de> for the patch.
102 6. Made an extension in the dump tape format capable of saving
103 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
104 wrote the extension and contributed the restore code back
105 into this codebase. The same extension mechanism will be
106 used in the future to save ACLs...
108 7. Made rmt work correctly with regard to QFA and local/remote
109 files and tapes. The remote access will however work only
110 when the dump provided rmt version is used. If you want to
111 use another rmt server, please do not use the QFA feature.
112 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
114 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
115 ====================================================================
117 1. Fixed the INSTALL file to reflect the actual install paths.
118 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
121 2. Fixed the configure script to only check for headers presence
122 instead of trying to compile them. This should fix issues
123 with old build environments. Thanks to Kari Lempiainen
124 <kari@funky.pp.fi> for reporting the bug.
126 3. Fixed restore to correctly ignore sockets when comparing
127 a dump (as socket cannot be properly restored anyway). Thanks
128 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
130 4. Fixed restore to correctly access the archive file (-A argument)
131 even when using a remote tape. Thanks to Fabrice Bellet
132 <fabrice@bellet.info> for reporting the bug.
134 5. Fixed (again) handling of long (largefile) seeks in rmt.
135 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
138 6. Fixed restore corner case when dealing with large block sizes
139 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
140 <fabrice@bellet.info> for reporting the bug.
142 7. Fixed a bug preventing dump to access a filesystem having
143 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
144 for reporting the bug.
146 8. Made dump store dump dates using explicit timezones, fixing a
147 problem with incremental dumps if the timezone is modified
148 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
149 the bug report and the patch.
151 9. Fixed a bug encountered when dumping individual files (not full
152 filesystems or directories) and dangling symbolic links happen
153 to be in the list of files. For as far as dump is concerned,
154 dangling symbolic links are allowed, and are dumped as is.
155 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
156 bug and providing the fix.
158 10. Fixed open and creation modes and permissions for QFA and
159 table-of-contents files in dump and restore. Thanks to
160 Philippe Troin <phil@fifi.org> for the patch.
162 11. Fixed the archive file descriptor handling enabling it to be 0.
163 This can happen in some cases when shell redirections are used.
164 Thanks to Philippe Troin <phil@fifi.org> for the patch.
166 12. Delayed the opening of archive file until after suid had been
167 dropped (fixing a possible security issue if dump is suid).
168 Thanks to Philippe Troin <phil@fifi.org> for the patch.
170 13. Fixed the 'S' command handling in the rmt client part.
171 Thanks to Philippe Troin <phil@fifi.org> for the patch.
173 14. Modified the end-of-tape script handling to print out statistics
174 (and stop the timer) before launching the eot script. Also, the eot
175 script does not get run anymore when using -M (which makes sense) or
176 when multiple tapes are listed on the command line
177 (-f tape0,tape1,tapen) (which also makes sense).
178 Thanks to Philippe Troin <phil@fifi.org> for the patch.
180 15. Relicensed dump/restore under the 'revised' BSD license, as per
181 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
183 16. Added LZO compression to dump. This new compression method has
184 the advantage of being super fast, thus not killing tape streaming
185 on slow machines. Thanks to Helmut Jarausch
186 <jarausch@igpm.rwth-aachen.de> for the patch and to
187 Markus Oberhumer <markus@oberhumer.com> for giving special permission
188 to include his miniLZO project (GPL licensed) in dump/restore.
190 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
191 <ant@notatla.demon.co.uk> for reporting the bugs.
193 18. Added a special rmt version which can do encryption when writing
194 to tape. Read examples/encrypted_rmt/README for details on
195 how to enable and configure it. Thanks to Ken Lalonde
196 <ken@globalremit.com> for the patch.
198 19. Made dump work with 2.5 kernel end of tape early warning semantics.
199 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
201 20. Fixed a bug which caused dump -w|-W not to work anymore, because
202 the fs_freq and fs_passno fields in /etc/mtab are always set
203 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
206 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
207 =======================================================================
209 1. Added a note in the restore man page clarifying the question
210 'set the permissions on the current directory ?' asked by
211 restore at the end of treatment in -i and -x modes.
213 2. Fixed the endianess issues when reading compressed tapes.
214 Thanks to Dark Force <daq4th@users.sourceforge.net> for
215 reporting this bug and providing test cases.
217 3. Fixed the "ACL won't be dumped" warning message (which showed
218 an extra, unrelated error message). Thanks to Dragan Krnic
219 <dkrnic@lycos.com> for reporting this bug.
221 4. Made dump look first into /etc/mtab, then into /etc/fstab
222 when searching for filesystem paths. Also fixed some problems
223 caused by binding mounts or multiple block device mounts.
224 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
225 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
226 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
227 and #160305, Sourceforge bugs #618699 and #679832).
229 5. Made dump's -I option accept the value '0' meaning all the
230 read errors will be ignored. This can be useful when running
231 dump from unattended sessions (like cron jobs). Thanks to
232 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
234 6. Fixed the output of dump to indicate 'blocks' instead of
235 'tape blocks' in the various messages (blocks are always
236 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
237 made it clearly print the current blocksize at the start of
238 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
241 7. Made rmt understand long (largefiles) seeks.
243 8. Fixed build with very old versions of libext2fs, where
244 EXT2_FT_* constants were undefined.
246 9. Made dump accept the dumpdates path on the command line
247 (-D file option) instead of using only the hardcoded one.
248 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
251 10. Enabled rmt, LFS, readline, QFA options by default in
252 ./configure. Updated the configure process (new versions
253 of config.guess, config.sub etc).
255 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
256 =======================================================================
258 1. Changed dump to use fcntl(F_SETLK) style locking instead
259 of flock() when locking the dumpdates file. With the old
260 locking scheme, a local user having read rights on the
261 dumpdates file could be able to do a Denial of Service attack
262 on dump. In order to lock the dumpdates file with the new
263 scheme, the user would need to have write access on the file.
264 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
265 reporting the bug (originally a bugtraq post).
267 2. Fixed interactive 'ls' which caused spurious errors warnings
268 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
269 <jorgen_ostling@users.sourceforge.net> for reporting this
272 3. Fixed dump's estimate when dealing with sparse inodes.
274 4. Modified dump to allow setting a blocksize bigger than 32kB
275 (raised the limit to 1024kB), because newer hardware needs
276 this for proper operation. Thanks to Dirk Traenapp
277 <dtraenapp@users.sourceforge.net> for reporting this.
279 5. Fixed a bug causing Dump to stop and report an error if an
280 inode number in the exclude file was followed by some amount
281 of whitespace. Thanks to Jeffrey Sofferin
282 <sofferin@users.sourceforge.net> for reporting this bug.
284 6. Fixed a bug which caused restore, in some particular cases,
285 to ask some 'scary' questions and leave a bunch of RSTTMP
286 directories behind when restoring incremental tapes. Thanks
287 to Philippe Troin <phil@fifi.org> for reporting this bug and
288 providing the test cases.
290 7. Changed the wording when inodes are excluded from dump:
291 replaced 'Added inode 7 to exclude list' with
292 'Excluding inode 7 (resize inode) from dump', as suggested
293 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
295 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
296 ===================================================================
298 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
299 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
300 <eros@lamel.bo.cnr.it> for reporting the bug.
302 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
303 ===================================================================
305 1. Made dump print out the ext2 logical block number in case of a read
306 error, which can be given as an argument to debugfs' ncheck command,
307 in order to find out the affected inode. Added note about this
308 usage in dump's man page.
310 2. Fixed a problem in restore when reading tapes written on big
311 endian machines with very old versions of dump. The patch was
312 contributed by George Helffrich <george@geology.bristol.ac.uk>.
314 3. Fixed the tape length calculation when using large tapes
315 and compression. Thanks to Georg Lippold
316 <g_lippold@sourceforge.net> for reporting the bug.
318 4. Added a new set of examples in dump_on_cd_2 directory, based
319 on dump_on_cd examples but somewhat enhanced, supporting DVD
320 media, and localized in english and german. Thanks to
321 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
323 5. Made dump save 32 bit UID/GID. Internally, this was achieved
324 by switching from the old BSD inode format to the new BSD
325 inode format, which means that the tape format was changed.
326 However, since all restore versions out there should
327 transparently support both inode formats, the change should
328 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
331 6. Fixed a lot of warnings in the code shown when compiling
332 with 'gcc -W'. Thanks to Matthias Andree
333 <matthias.andree@stud.uni-dortmund.de> for reporting this.
335 7. Fixed a small markup bug in the dump man page. Thanks to
336 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
339 8. Rewrote entirely the man pages using the tmac.an macro
340 package (Linux man page format) instead of the original BSD
341 format. They should be now cleaner and easier to modify.
343 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
344 ==================================================================
346 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
347 non Linux clients were misinterpreted. The description of the problem
348 (incompatible numbering in Linux mtio opcodes) is documented at
349 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
350 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
351 providing an excellent, cross-platform replacement for rmt in his
354 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
355 which caused restore to fail when the inode maps were not entirely
356 contained on the first volume (when using really small volumes or
357 when dumping a huge number of inodes).
359 3. Fixed a problem in dump, where files in subdirectories of directories
360 that have the nodump flag set (or being excluded with -e/-E) were
361 sometimes incorrectly dumped (instead of being excluded). The original
362 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
363 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
364 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
365 help testing the patch.
367 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
368 which makes one able to pipe the output of dump, by the net, to
369 a remote CD-burner server.
371 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
372 and use GNU's symbolic syntax over rmt instead of numerical values
373 to assure multiple platform compatibility.
375 6. Documented the -d option in restore.
377 7. Added a -v (verbose) mode to dump. For now it just prints the number
378 of the inode being dumped, but this could evolve in future versions
379 to include interesting debugging output.
381 8. Added a -o flag to restore, which automatically restores the current
382 directory permissions in -i or -x mode, without asking the operator
383 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
384 and Peter Samuel <peters@e-smith.com>.
386 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
387 ====================================================================
389 1. Fixed a bug in the QFA feature which could have caused
390 a bad tape positionning on restore (causing extra delays in
391 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
393 2. Added a small note in the dump man page specifying that
394 there should be no white space between the option letter and
395 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
397 3. Made restore work with older versions of the readline library,
398 by checking in configure for several extended symbols. Restore
399 can now be compiled with a readline as old as the 2.0 release
400 (though it may be a good idea to upgrade it to a more recent
401 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
402 reporting the build failures.
404 4. Fixed a performance problem with the QFA file creation in
405 dump, which made unnecessary seeks on the tape slowing down
406 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
407 reporting this issue.
409 5. Removed the inclusion of some kernel headers in the dump
410 source, which prevented the compile in some kernel/glibc
411 headers/architecture combination. Thanks to Bdale Garbee
412 <bdale@gag.com> for reporting the bug.
414 6. Added the appropriate error message when dump fails to
415 open the output file for writing. Thanks to Amith Varghese
416 <amithv@yahoo.com> for reporting this bug.
418 7. Made restore able to understand large Solaris ufsdump tapes
419 (containing inodes bigger than 4194304). Sun have introduced
420 an "extension" to the dump tape format when dealing with
421 those inodes, which was uncorrectly handled by Linux restore.
422 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
423 providing a test case.
425 8. Added the -m parameter to dump which optimises the output for
426 inodes having been changed but not modified since the last dump
427 ('changed' and 'modified' have the meaning defined in stat(2)).
428 For those inodes, dump will save only the metadata, instead of
429 saving the entire inode contents. Inodes which are either
430 directories or have been modified since the last dump are saved
431 in a regular way. Uses of this flag must be consistent, meaning
432 that either every dump in an incremental dump set have the flag,
435 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
436 =======================================================================
438 1. Fixed behaviour of dump when exceeding resource limits
441 2. Added the -L flag to restore to allow the user to specify a
442 maximal allowed number of miscompares when using restore
443 with the -C option to check the backup.
445 3. Detailed the manual entry for the -N option of restore.
447 4. Added the -a flag to restore to make able doing unattended
448 restores in -i or -x mode (automatically walks through the
449 multiple dump volumes).
451 5. Extended the QFA mode to work with local files and/or
452 remote tapes and files. This way, restore can know in advance
453 the tape number and the offset for the inodes to extract and
454 can minimize the extraction time by seeking directly to the
457 6. Added the -A <archive> option to both dump and restore,
458 which makes dump to archive a dump table-of-contents in
459 the specified file to be used by restore to determine
460 whether a file is in the dump file that is being restored.
461 (the archive file syntax is also compatible with the
462 Solaris ufsdump generated one).
464 7. Small fix in restore making it able to read some (broken ?)
465 Solaris ufsdump tapes.
467 8. Fixed dump to correctly recognise the root filesystem when using
468 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
469 for reporting this bug.
471 9. Added the -P <file> option to restore to create a
472 Quick File Access file from an already made dump. Patch
473 contributed by Uwe Gohlke <uwe@ugsoft.de>.
475 10. Made restore compile and run on Solaris, making it a
476 possible replacement for the standard ufsrestore. Port was
477 contributed by Uwe Gohlke <uwe@ugsoft.de>.
479 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
480 =====================================================================
482 1. Added a set of backup scripts from Eugenio Diaz
483 <getnito@yahoo.com> in the examples section. It features
484 automatic (cron based) full and incremental dumping of
485 several filesystems on a separate filesystem.
487 2. Fixed a off-by-one miscalculation which disabled dumping
488 a one letter subdirectory. Thanks to Chris Siebenmann
489 <cks@utcc.utoronto.ca> for reporting the bug.
491 3. Fixed several restore bugs occuring when trying to
492 restore some missing files on the tape. Thanks to Chris
493 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
495 4. Fixed --with-ldopts configure argument passing, installing from
496 a separate object directory, makefile cleanups contributed
497 by <splite@purdue.edu>.
499 5. Fix a bug which could caused, in some conditions, the highest
500 number inode of a filesystem, to not be dumped. Many thanks
501 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
504 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
505 =======================================================================
507 1. Added a mini howto from Patrick Walsh in the examples
510 2. Minor man pages syntax corrections. Thanks to
511 Chris Danis <screechco@home.com> for reporting the bugs.
513 3. Added a script from David B. Peterson <dave@toppledwagon.com>
514 to the examples section. It features dumping several
515 filesystems to a remote tape drive upon ssh.
517 4. Added a patch provided by Richard Jones <rich@annexia.org>
518 which allows BRADEMAX (number of read errors tolerated by
519 dump) to be adjusted using the -I option.
521 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
522 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
525 6. Add the -l option to restore to specify if, when doing a
526 remote restore, the file used to access the backup is a
527 regular file (the defaults being a tape drive). Restore needs
528 to know this information when reading a remote compressed
529 dump. Previously, this information was autodetected, but
530 the autodetection code fails (with ioctl: Inappropriate ioctl
531 for device) when using a non Linux remote box. Thanks to
532 many users and especially to Eros Albertazzi
533 <eros@lamel.bo.cnr.it> for reporting this.
535 7. Found a workaroung for the dump deadlock problem (3 childs
536 stuck in pause(), father in read()). The workaround seems
537 to work for me and several beta-testers. If it doesn't work
538 for you, please report back.
540 8. Updated the RPM spec file (BuildPrereq, URL etc).
542 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
543 ========================================================================
545 1. Fixed the permissions of a newly created QFA file by dump.
547 2. Cleaned up the source of dump (the external variables
548 definition was a complete mess, making possible to have
551 3. Fixed restore to use the full tape volume path when doing
552 a compare (since it changes the working directory to the
553 filesystem being compared in the process).
555 4. Added the -q option to dump which makes dump abort
556 whenever it needs operator attention. It should be
557 easier to use dump in scripts with this option.
559 5. Detect the use of incompatible options to dump and
560 refuse them (like -a and -B options together).
562 6. Added bzip2 compression to dump/restore (use option -j level
563 to select it). Note that you will need a restore version
564 >= 0.4b24 in order to restore a bzip2 compressed dump.
565 The same warning as for the zlib compression applies:
566 the tape format of a bzip2 dump is not compatible with the
567 original BSD tape format.
569 7. Fixed a overflow problem in dump corrupting the dump when
570 very large files were encountered. Thanks to Vladimir Nadvornik
573 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
574 kernel buffer/page cache before starting the dump, helping
575 a bit those who use dump on mounted filesystems. Thanks to
576 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
579 9. Updated the RPM spec file following the RedHat changes
580 (dynamically linked binaries now in /usr/sbin etc).
582 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
583 which enables restore to recognise multi volume compressed dumps
584 done on CD. Included his scripts for dump (which pipe the dump
585 output directly into cdrecord) and restore. There is now
586 possible to to backups to CD on the fly!
588 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
589 ===================================================================
591 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
592 Marcus Meissner (Caldera International Security Dept.).
594 2. Implement the Sun rmt extended protocol. Patch submitted
595 by Ian Gordon <iangordon@users.sourceforge.net>.
597 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
598 the linux kernel header. This ensures that dump always has the
599 latest version of this file. Patch submitted by
600 Andreas Dilger <adilger@turbolinux.com>.
602 4. Report any filesystem present in either /etc/fstab with a
603 positive passno or /etc/dumpdates in dump -w output.
604 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
606 5. Fixed the looping problem in dump introduced in the
609 6. Changed the -B option of dump to limit the size of
610 _compressed_ output per volume if compression is on.
611 Patch contributed by Helmut Jarausch
612 <jarausch@igpm.rwth-aachen.de>. Note however that, since
613 it is impossible to predict the size of the compressed
614 data before doing the compression, the -B limit is a bit
617 7. Fixed a bug in reading the operator typed file/tape path for
618 the next volume in restore.
620 8. Implemented a "-F script" option to restore which permits the
621 user to specify a script which will be launched at the
622 beginning of each tape, useful for automatic programming of
623 tape changers for example. See the restore man page for the
624 script parameters and return codes.
626 9. Small fix for the QFA routines provided by Uwe Gohlke
627 <uwe@ugsoft.de>, and some recommendations for QFA uses in
630 10. Fixed the multivolume restoring where making a mistake
631 to the 'Mount next tape' prompt caused several blocks to
634 11. Enhanced the -e option of dump to take as a parameter a
635 comma separated list of inode numbers.
637 12. Added the -E option to dump which specify a file containing
638 inode numbers to exclude from the dump.
640 13. Fixed the compressed multi-volume dump + restore.
642 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
643 ==================================================================
645 1. Made dump report the number of blocks dumped per volume.
646 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
648 2. Fix a bug in dump where waiting too much at the 'change volumes'
649 question caused the volume to be rewritten. Thanks to
650 Graham Reed <greed@users.sourceforge.net> for reporting the
651 bug and providing a patch.
653 3. Added a compression option to dump, contributed by Jerry
654 Peters <gapeters@worldnet.att.net>.
656 WARNING: the compression works only on files/pipes and
657 drives supporting variable block size.
659 WARNING2: tapes created using the compression feature are
660 incompatible with the standard dump tape format, and a
661 version of restore >= 0.4b22 will be needed for extraction.
663 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
664 architectures. Thanks to Paul Slootman <paul@debian.org> for
665 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
668 5. Many cleanups (CPP defines, const char warnings, check of
669 ext2fs COMPAT flags, time_t cleanups, added libext2 version
670 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
672 6. Made --prefix option work in configure. All the install path
673 are now based on the configure parameters.
675 7. Added the Quick File Access mode in dump/restore, contributed
676 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
677 a file tape position for each inode, and this file is used by
678 restore (if called with parameter Q and the filename)
679 to directly position the tape at the file restore is currently
680 working on. This saves hours when restoring single files from
681 large backups, saves the tapes and the drive's head. Use
682 --enable-qfa option of configure to compile in the QFA support.
684 8. Added the possibility to dump several files and directories
685 in a single invocation of dump. Thanks to Uwe Gohlke
686 <uwe@ugsoft.de> for implementing this option.
688 9. Fixed the dumping and restoring of files with holes
689 (files ending with holes didn't get dumped or restored
692 10. Fixed a socket descriptor leak in dump, which leaved opened
693 3 file descriptors per dump process (and there is one dump
696 11. Fixed dump large file system support, by explicit use of
697 open64/lseek64/etc functions (explicit use needed because
698 e2fsprogs libraries don't behave well when compiled with
699 FILE_OFFSET_BITS=64).
701 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
702 ======================================================================
704 1. Fixed some bugs in the dump -w|-W logic introduced by
705 the previous version. Thanks to Andreas Dilger
706 <adilger@turbolinux.com> for his help on this one.
708 2. Fixed again a compilation problem when using old e2fs
709 headers (filesystem label related). Thanks to many users
710 who reported this stupid error.
712 3. Fixed a build problem on old lib5 based systems dealing with
713 _PATH_MNTTAB being undefined. Thanks to John Adams
714 <johna@onevista.com> for reporting the bug.
716 4. Improved the error detection in restore when creating
717 the temporary files in TMPDIR. Now restore will corectly
718 report a 'no space left on device' error instead of
719 strange errors which could imply an archive corruption.
720 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
721 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
723 5. Added the throughput information in dump's progression
724 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
727 6. Use libext2fs's inode scanning routines, which are particularly
728 robust when dealing with errors (especially when having some
729 bad blocks on the filesystem). Many thanks to Colin
730 <colin@horizon.com> for reporting the bug, investigating
731 the issues, finding a workaround, writing the patch and
732 fully testing it... (of course, if this patch will break
733 anything, he is to blame for :-)).
735 7. Made dump and restore LFS aware. Dump can dump a filesystem
736 containing large files, generate a large file on output and
737 restore can restore them. This feature is not enabled by
738 default, use --enable-largefile option of configure to enable
739 it (you need to have a LFS aware glibc though). Thanks to
740 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
741 and to Theodore T'so <tytso@valinux.com> for his always
744 8. Made dump ask upon a tape write error if it should rewrite
745 the current volume (assume this is a bad tape) or if it should
746 assume an end-of-tape condition (useful for tape drives which
747 behaves badly at the end of the tape). Thanks to Andreas
748 Dilger <adilger@turbolinux.com> for the suggestion.
750 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
751 =======================================================================
753 1. Fixed a small compilation problem due to a change
754 in the definintion of the struct sigaction in
755 glibc 2.0 / libc5. Thanks to Gunther Schlegel
756 <schlegel@riege.de> for reporting the bug and to
757 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
760 2. Modified the label and uuid analysis in order to be
761 self-contained (independant of kernel/libc headers). This
762 should fix the compile with older kernel/libc headers and
763 will preserve the functionality. Thanks to Bernhard Erdmann
764 <bernhard.erdmann@gmx.de> for reporting the bug.
766 3. The 'exclude inode' option, if applied to a directory
767 inode, excludes now correctly all the leaves of this
768 directory. Thanks to John R. Dennison
769 <gerdesas@users.sourceforge.net> for reporting the bug.
771 4. Fixed the '-e' option to disable the possibility
772 to exclude the root inode (which causes the dumps to
773 be unreadable by restore). Prevented array overflow
774 when multiple -e options are used.
776 5. Fixed dump to correctly interpret a filesystem argument
777 which is a mountpoint and it is not an absolute path
778 (as specified in the fstab). Thanks to Bernhard R. Erdmann
779 <be@berdmann.de> for reporting the bug.
781 6. Made dump able to backup files larger than 2 GB. Note that
782 dump still doesn't cope with files larger than 4 GB.
784 7. Restore the real uid and gid before invoking an external
785 RSH program (big hole when dump or restore is suid root!).
787 8. Get the values for the default tape device and the location
788 of fstab file from the system headers. Thanks to
789 Andreas Dilger <adilger@turbolinux.com> for the patch.
791 9. Made dump -w|-W report all recognized filesystems
792 present in either /etc/fstab or /etc/dumpdates, and present
793 the list in the same order as in fstab file. Thanks
794 to Andreas Dilger <adilger@turbolinux.com> for the patch.
796 10. Made dump's -a (automatic end of tape detection) the
797 default. Specifying one of -B, -c, -d or -s options will
798 override the EOM detection. Thanks to Andreas Dilger
799 <adilger@turbolinux.com> for the patch.
801 11. Save the ext2 filesystem label into the dump volume label.
802 Specifying a volume label on the command line (-L option)
803 will override this feature. Thanks to Andreas Dilger
804 <adilger@turbolinux.com> for the patch.
806 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
807 =====================================================================
809 1. Fixed the signal handling in dump (which I broke in 0.4b17)
810 which was causing several strange dump failures (dump
811 hanged or segmentation faults etc).
813 2. Specified the default blocksize in the dump man page.
815 3. Changed two info messages of restore to be written on stdout
816 instead of stderr in order to leave stderr only for errors
817 or warnings. Thanks to Stephen Atwell
818 <satwell@urbana.css.mot.com> for the suggestion.
820 4. Corrected an off by one calculation which prevented
821 dumping a directory having a 1 character name length.
822 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
823 for reporting the bug.
825 5. Reinforce dump in order to allow only level 0 and no
826 -u option when dumping a subdirectory, and document
827 this in the man page. Thanks to Bernhard Erdmann
828 <bernhard.erdmann@gmx.de> for reporting the bug.
830 6. Fixed a small harmless bug in restore which caused
831 in some conditions hard links to be restored several
832 times (therefore generation some warning messages).
833 Thanks to Kenneth Porter <shiva@well.com> for
836 7. Updated the RPM spec file to the latest RedHat version,
837 providing FHS packaging and other cosmetic changes.
838 You will need RPM version >= 3.0.5 in order to build the RPM.
840 8. Updated the configure script to check for libtermcap
841 before checking for libreadline, because we need this
842 library in order to compile the readline support.
844 9. Made dump understand the LABEL= and UUID= notation
845 both in /etc/fstab and on the command line. Note that
846 you will need the /proc filesystem in order to use
847 these notations. Thanks to Erik Troan <ewt@redhat.com>
848 for providing the patch.
850 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
851 ===================================================================
853 1. Fixed a potential buffer overflow in restore. Thanks
854 to Stan Bubrouski <satan@fastdial.net> for reporting
857 2. Fixed a readline-related bug which prevented
858 'cat DUMPFILE | restore -i -f -' from working. Thanks
859 to Charles Karney <karney@users.sourceforge.net>
862 3. Changed a few "panic" into "exit", causing restore to
863 be more stable against some attacks (like the last one
864 reported on Bugtraq, although the last version of restore
865 was not vulnerable - just dumped core). Thanks to
866 Andreas Hasenack <andreas@conectiva.com.br> for reporting
869 4. Removed the suid-root bit on dump and restore in the
870 default build (and generated RPMs). It should be safer
871 now. Users who need the suid-root capabilities in order
872 to make network backups should read first the man page
873 of dump and enable the suid bit manually.
875 5. Added -ltermcap to the compile parameters for restore
876 when using readline support, in order to make the compile
877 process work on some systems (SuSE ?). Thanks to
878 Patrik Schindler <poc@pocnet.net> for reporting the bug.
880 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
881 ====================================================================
883 1. The -F script is called now *only* at the end of a tape,
884 not at the end of the dump. Thanks to Christian Haul
885 <haul@informatik.tu-darmstadt.de> for the bug report.
887 Normally, the device name and the current volume number
888 are passed on the command line of the script. However,
889 if you want the old style script (with no arguments
890 passed on the command line), you can enable it in
891 configure with the --enable-oldstylefscript.
893 2. Use posix signal handling to preserve dump functionality
894 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
897 3. Made the exit code of restore in case of a 'C'ompare
898 command reflect the result of the compare. An exit status
899 of 0 means the dump archive is correct, 1 means tape errors,
900 2 means that some files were modified. Thanks to Kenneth Porter
901 <shiva@well.com> for the suggestion.
903 4. Made (finally) quotes work in interactive restore.
905 5. Small fixes in order to allow dump to compile with a
906 really old e2fsprogs version. Thanks to Ian Zimmerman
907 <itz@speakeasy.org> for the bug report.
909 6. Add GNU readline capabilities to interactive restore.
910 Use configure's --enable-readline flag to enable this feature.
911 Thanks to Patrik Schindler <poc@pocnet.net> for the
914 7. Do the compare on the fly in restore 'C' mode (this will
915 allow not to exhaust the available /tmp space when
916 ccmparing large files). Thanks to Kenneth Porter
917 <shiva@well.com> for the suggestion.
919 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
920 ====================================================================
922 1. Fixed some several duplicate 'DUMP: DUMP:' in the
925 2. Corrected the estimation of blocks to dump. Note that
926 this is still wrong for large directory inodes, due
927 to the size of a BSD directory entry on the tape
928 (estimation is based on the size of the ext2 directory,
929 which is smaller because it doesn't contain the null
930 character at the end).
932 3. Made dump report the total number of MB written to
933 tape at the end of run. Thanks to W. Reilly Cooley
934 <wcooley@nakedape.cc> for the patch.
936 4. Added the -X option to restore giving the possibility
937 to read the names of the files to be extracted/listed
938 from a text file (in addition of the command line).
939 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
942 5. Added the device name and the current volume number
943 as arguments to the end of tape script (dump -F option).
945 6. Made the multi-volume dump work again (after having
946 broken it in 0.4b15).
948 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
949 ===================================================================
951 1. Added a prompt command in interactive restore mode. Thanks
952 to Andreas Dilger <adilger@home.com> for the patch.
954 2. Fixed a buffer overflow problem in dump (caused by
955 not checking the size of the filesystem parameter).
956 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
957 reporting this on Bugtraq (and to several dump users
958 who forwarded me his mail).
960 3. Added the '-F script' option to dump in order to
961 launch a script at the end of each tape (to be used
962 with a tape changer, or to notify the sysadmin by
965 4. Fixed a bug in restore compare code caused by the changes
968 5. Fixed the treatment of options using the old BSD syntax
969 in both dump and restore.
971 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
972 =======================================================================
974 1. Fixed a bug in dump which may have caused invalid deleted
975 directories to be dumped out if they were deleted after the
976 mapping pass. This could occure on active filesystem and lead
977 to heap corruption (causing dump malfunction in many possible ways).
978 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
979 bug and submitting the patch.
981 2. Fixed the handling of the filesystem parameter in dump. A
982 '/mnt/disk' parameter caused the disk contents to be dumped,
983 but a '/mnt/disk/' parameter caused the mountpoint directory
984 to be dumped (generally an empty directory).
986 3. Improved the output of dump in order to tell which directory
987 it is currently dumping (when dumping a subtree).
989 4. Added the '-e' exclude inode option to dump. Thanks to
990 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
992 5. Added a REPORTING-BUGS file in order to provide a guide
993 on how to correctly report a bug in dump/restore.
995 6. Fixed a restore problem when restoring a hard link to an inode
996 having the immutable or append-only attribute set. Thanks to
997 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
999 7. Fixed a compatibility problem between dumps made on little
1000 endian machines (the format was correct) and big endian
1001 machines (the format was incorrect). This fix break the
1002 compatibility with the older dumps made on big endian
1003 machines (sparc, m86k, ppc etc). For the first time in
1004 linux dump's history (I believe), the dumps made by *BSD,
1005 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1006 so interchangeable. Thanks to Rob Cermak
1007 <cermak@ahab.rutgers.edu> for submitting the bug and
1008 helping me test the fix.
1010 8. Fixed the way dump reports the remaining percent/time, if
1011 the number of blocks actually dumped exceeds the estimated
1012 number of blocks. Thanks to Jean-Paul van der Jagt
1013 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1015 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1016 ======================================================================
1018 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1019 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1021 2. Removed the requirement to build the RPM as root from the
1022 spec file. Thanks to Christian Weisgerber
1023 <naddy@mips.rhein-neckar.de> for submitting this.
1025 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1026 causing dump to block when dumping really huge filesystems.
1027 Many thanks to Patrik Schindler <poc@pocnet.net> for
1028 helping me find this bug.
1030 4. Fixed the treatment for an interrupt signal when dump access
1031 the remote tape through RSH. Thanks to Christian Weisgerber
1032 <naddy@mips.rhein-neckar.de> for providing the patch.
1034 5. Fixed a bug which was causing dump/restore to display
1035 garbage characters instead of the remote host name.
1037 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1038 =====================================================================
1040 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1041 <kukuk@suse.de> for submitting the patch.
1043 2. Fix for the exit code when using the size estimate option of
1044 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1045 submitting the patch.
1047 3. Handle EINTR in atomical reads/writes in dump, which was causing
1048 dump to fail on some systems. Thanks to Eric Jergensen
1049 <eric@dvns.com> for reporting the bug and submitting the patch.
1051 4. Handle more than 16 characters for the device names in dumpdates.
1052 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1053 tracking down the problem and proposing the solution.
1055 5. Fixed a bug in dump which prevented the creation of the
1056 dumpdates file when doing a 0-level dump without already
1057 having a dumpdates file. Thanks to Patrik Schindler
1058 <poc@pocnet.net> for reporting the bug.
1060 6. Changed the way dump 'S' flag reports the size estimate
1061 from number of blocks into bytes (making it compatible
1062 with the Solaris version, and simplifying things for
1063 amanda users). Thanks to Jason L Tibbitts III
1064 <tibbs@math.uh.edu> for reporting the bug.
1066 7. Fixed a compatibility problem in linux/alpha dump tape format.
1067 Now the linux/alpha dump are (again) compatible with the
1068 other dump formats. But this breaks compatibility with
1069 older dumps made on alpha. Thanks to Mike Tibor
1070 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1072 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1073 ======================================================================
1075 1. Added a '--enable-kerberos' to configure.
1077 2. Added a 'S' option to dump which determines the amount of space
1078 that is needed to perform the dump without actually doing it, similar
1079 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1080 <cermak@ahab.rutgers.edu>.
1082 3. Added a 'M' multi-volume option to dump and restore which enables
1083 dumping to multiple files (useful when dumping to an ext2
1084 partition to make several dump files in order to bypass the 2GB
1085 file size limitation). The 'f' argument is treated as a prefix and
1086 the output files will be named <prefix>001, <prefix>002 etc. With
1087 the 'M' flag, restore automatically selects the right file without
1088 asking to enter a new tape each time.
1090 4. Fixed a memory leak which was causing dump to grow very big
1091 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1092 Fearon <jasonf@netrider.org.au> for reporting the bug.
1094 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1095 ======================================================================
1097 1. Make configure test if the system glob routines support
1098 extended syntax (ALTDIRFUNC). If not, use the internal glob
1099 routines instead of system ones. Thanks to Bernhard Sadlowski
1100 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1101 and helping me resolve this and other minor libc5 compiling
1104 2. Fix a problem when dumping a ext2fs with the 'filetype'
1105 feature enabled. Thanks to Patrick J. LoPresti
1106 <patl@cag.lcs.mit.edu> for reporting the bug and to
1107 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1109 3. Made the nodump flag work on directories. A directory which
1110 has the nodump flag gets never dumped, regardless of its
1113 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1114 which allows dump on an active ext3 filesystem. However, this
1115 is a "quick and dirty" patch which enables backup of an ext3
1116 filesystem through the ext2 compatibility (by ignoring the
1117 NEEDS_RECOVERY bit). The journal file is not recognized and
1118 it is dumped (it should not).
1120 5. Test the superblock compatibility flags when dumping, in order
1121 to be sure that we know how to deal with specific features.
1123 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1124 ====================================================================
1126 1. Use lchown instead of chown, fixing a possible security problem
1127 when restoring symlinks (a malicious user could use this
1128 to deliberately corrupt the ownership of important system files).
1129 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1130 this and providing the patch.
1132 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1133 ====================================================================
1135 1. Put dump sources under CVS, added Id tags in all files so
1136 one can use 'ident' on binary files.
1138 2. Added the dump/restore version in the usage text so one can
1139 easily verify the version he is using.
1141 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1142 a va_start/va_end problem on linux-ppc (always call va_start
1143 va_end in pairs each time we use a vararg function).
1145 4. Added again the DT_* constants because old libc does not
1146 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1147 for submitting the bug report.
1149 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1150 this should enable dumping big (huge) filesystems.
1152 6. Added the RSH environment variable in order to be able to
1153 use a rsh replacement like ssh when doing remote backups (and
1154 bypass the security limitations of rcmd). Now you can do remote
1155 backups without being root (or making dump setuid root).
1157 7. Modified again the way dumpdates works. For incremental dumps,
1158 we need to read dumpdates even if we are not using 'u' option.
1159 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1162 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1163 ===================================================================
1165 1. Removed the 'k' flag from the restore 'about' text if kerberos
1166 was not compiled in.
1168 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1169 to them (fsetflags takes a char*, setflags an open fd!).
1171 3. (f)setflags is called only if the flags aren't empty. If the
1172 file is a special file, a warning is printed, because changing
1173 flags implies opening the device. Normally, a special file
1174 should not have any flag... (Debian bug #29775, patch provided
1175 by Abhijit Dasgupta <abhijit@ans.net>).
1177 4. Made possible to dump a file system not mentioned in /etc/fstab.
1178 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1180 5. Changed the default behaviour to not create dumpdates
1181 unless 'u' option is specified. Removed the old "debian-patch"
1182 which provided the same thing. (Debian bug #38136, #33818).
1184 6. Removed all those dump*announce, since they were getting old...
1186 7. Added warning messages if dumpdates does not exist and
1187 when an inferior level dump does not exist (except for a level 0
1190 8. Debugged the glob calls in interactive mode: restore used a
1191 dirent struct which was different from the /usr/include/dirent.h
1192 one (this used to work, is it a glibc2 change?), so none of the
1193 compat glob (which used /usr/include/dirent.h) or the system glob
1194 worked. Restore use now the system dirent (and the system
1195 DT_* constants), which are compatible with BSD ones.
1197 9. Added a configure flag (--with-dumpdatespath) to specify
1198 the location of dumpdates file. By default, it is
1201 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1202 included the current date/version in man pages.
1204 11. Corrected the estimation of remaining time when
1205 the operator doesn't change the tapes quickly enough. This
1206 was an old bug, I thought I corrected it, and discovered
1207 that in fact it was corrected in two different places, so
1208 the results canceled each other...
1210 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1211 ===================================================================
1213 1. Integrated multiple patches from RedHat, Debian and SuSE:
1215 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1217 - several fixes in the man pages.
1218 - update the default tape device to /dev/st0.
1219 - many updates for Linux Alpha (byte ordering, size_t etc).
1221 - use environment variable for TMPDIR (instead of /tmp).
1222 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1223 - workaround egcs bug (RedHat bugs #4281 and #2989).
1224 - wire $(OPT) throughout Makefile's.
1226 2. Upgrade the dump revision to 1, making possible to dump filesystems
1227 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1229 3. Fix some compile warnings, prototype all functions.
1231 4. Use glibc err/glob instead of internal compatibility
1232 routines (only if available).
1234 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1235 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1237 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1238 ======================================================================
1240 1. Integrated the changes from FreeBSD-3.1-RELEASE
1241 (mostly bug fixes, buffer overruns, dump has now an "automatic
1242 tape length calculation" flag, dump/restore can use kerberos now
1243 (this is NOT tested), use environment variables for TAPE and
1246 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1248 3. Corrected a bug in restore when using 'C' option with multi-volumes
1249 tapes (files splited accros two tapes give "size changed" errors
1252 4. Corrected the long standing bug when dumping multiple tapes.
1253 This works for me, needs further testing.
1255 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1256 ====================================================================
1258 1. Dump now runs correctly on kernels 2.1.x
1259 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1261 Changes between versions 0.4b2 and 0.4b3
1262 ========================================
1264 1. Use realpath() if available
1266 2. Report statistics
1268 Changes between versions 0.4b1 and 0.4b2
1269 ========================================
1271 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1274 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1276 3. Fixed configure.in to correctly handle --enable-rmt
1278 Changes between versions 0.3 and 0.4b1
1279 ======================================
1281 1. Integrated the changes from 4.4BSD-Lite2
1283 2. Integrated the patches from Debian and Red Hat
1285 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1287 4. Changed dump to use the Ext2fs library to get block addresses. This
1288 should solve the endianness problem on SparcLinux.
1290 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1291 distribution's one) to use autoconf
1293 6. Fixed a few minor bugs
1295 Changes between versions 0.2e and 0.2f
1296 ======================================
1298 1. Added the creation of named pipes (fifos) in restore.
1300 2. Added the -N flag in the restore manual page.
1302 3. Added the file kernel.patch which contains the llseek() optimization
1303 patch for 1.2.x kernels.
1305 4. Fixed a bug in the restoration of symbolic links: owner and group were
1308 5. Integrated some changes from FreeBSD 2.2.
1310 6. Added a call to ftruncate() after restoring each file to restore
1311 correctly files ending by a hole.
1313 Changes between versions 0.2d and 0.2e
1314 ======================================
1316 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1317 with owner = root (0) and group = root/wheel/whatever (0).
1319 Changes between versions 0.2c and 0.2d
1320 ======================================
1322 1. Dump is now able to backup 2GB+ filesystems.
1324 2. Dump and restore can now be linked as static binaries.
1326 Changes between versions 0.2b and 0.2c
1327 ======================================
1329 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1331 Changes between versions 0.2a and 0.2b
1332 ======================================
1334 1. Really fixed the bug that I should have corrected in 0.2a.
1336 2. Enabled optimization again.
1338 Changes between versions 0.2 and 0.2a
1339 =====================================
1341 1. Disabled the optimization during compilation.
1343 Changes between versions 0.1 and 0.2
1344 ====================================
1346 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1347 the fs_type field (actually, I modified the file fstab.c to make it
1348 use the mntent functions).
1350 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1351 made by dump should be readable by the BSD restore and backups made
1352 by the BSD dump should be readable by restore. Unfortunately, this
1353 means that the dump format has changed between version 0.1 and version
1356 3. Dump is now able to backup a subtree, it is no longer limited to whole
1357 filesystems like the BSD version.
1359 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1362 Changes between versions 0.0 and 0.1
1363 ====================================
1365 1. Now create links rdump and rrestore during the `make install' step.
1367 2. Linux port specific bugs added to the manual pages
1369 3. Incorrect estimation of the number of tapes blocks fixed when doing
1370 incremental backups.
1372 4. Better ls-like format in restore in interactive mode.
