3 Changes between versions 0.4b35 and 0.4b36 (released ?????????????????)
4 =======================================================================
6 1. Fixed dump compilation with old gcc versions. Thanks to
7 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
9 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
10 when compiling against a recent glibc version.
12 3. Fixed a bug in restore preventing the read of a dump tape
13 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
14 <phiggins@transzap.com> for reporting the bug and providing
17 4. Changed dump to enable the creation of volumes of different
18 sizes in a single run (make -B accept a list of values).
19 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
21 5. Use the glibc provided minor() and major() macros instead
22 of our own bitmask implementation. This should be safe for
23 when the major/minor namespace will migrate to 32 bits.
24 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
27 6. Made explicit in the dump man page that dump will not create
28 a remote file, it will only write to an already existing one.
30 7. Another try at making size estimates better again.
32 8. Put back the inconditional running of the end-of-tape
33 script which was changed in 0.434 to be run only when -M
34 or multiple -f were NOT specified. Some users rely on this
35 feature even when it is combined with -M/-f.
37 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
38 =======================================================================
40 1. Added a note in the dump man page saying that the default
41 blocksize can be 32 if -d is used with a high density argument.
42 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
45 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
46 LDFLAGS environment variables. Thanks to Arcady Genkin
47 <antipode@users.sourceforge.net> for reporting the bug.
49 3. Made -e/-E options of dump accept an unlimited number of inodes
50 to be excluded, rather than a hardcoded maximum. Thanks to
51 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
53 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
54 and -D_USE_BSD_SIGNAL defines in configure in order to solve
55 64bit build problems because quad_t is redifined with a
56 different signature. Thanks to Mike Harris <mharris@redhat.com>
57 for reporting this bug.
59 5. Made restore build on Solaris, making possible to
60 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
61 <uwe@ugsoft.de> for the patch.
63 6. Made an extension in the dump tape format capable of saving
64 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
65 wrote the extension and contributed the restore code back
66 into this codebase. The same extension mechanism will be
67 used in the future to save ACLs...
69 7. Made rmt work correctly with regard to QFA and local/remote
70 files and tapes. The remote access will however work only
71 when the dump provided rmt version is used. If you want to
72 use another rmt server, please do not use the QFA feature.
73 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
75 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
76 ====================================================================
78 1. Fixed the INSTALL file to reflect the actual install paths.
79 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
82 2. Fixed the configure script to only check for headers presence
83 instead of trying to compile them. This should fix issues
84 with old build environments. Thanks to Kari Lempiainen
85 <kari@funky.pp.fi> for reporting the bug.
87 3. Fixed restore to correctly ignore sockets when comparing
88 a dump (as socket cannot be properly restored anyway). Thanks
89 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
91 4. Fixed restore to correctly access the archive file (-A argument)
92 even when using a remote tape. Thanks to Fabrice Bellet
93 <fabrice@bellet.info> for reporting the bug.
95 5. Fixed (again) handling of long (largefile) seeks in rmt.
96 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
99 6. Fixed restore corner case when dealing with large block sizes
100 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
101 <fabrice@bellet.info> for reporting the bug.
103 7. Fixed a bug preventing dump to access a filesystem having
104 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
105 for reporting the bug.
107 8. Made dump store dump dates using explicit timezones, fixing a
108 problem with incremental dumps if the timezone is modified
109 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
110 the bug report and the patch.
112 9. Fixed a bug encountered when dumping individual files (not full
113 filesystems or directories) and dangling symbolic links happen
114 to be in the list of files. For as far as dump is concerned,
115 dangling symbolic links are allowed, and are dumped as is.
116 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
117 bug and providing the fix.
119 10. Fixed open and creation modes and permissions for QFA and
120 table-of-contents files in dump and restore. Thanks to
121 Philippe Troin <phil@fifi.org> for the patch.
123 11. Fixed the archive file descriptor handling enabling it to be 0.
124 This can happen in some cases when shell redirections are used.
125 Thanks to Philippe Troin <phil@fifi.org> for the patch.
127 12. Delayed the opening of archive file until after suid had been
128 dropped (fixing a possible security issue if dump is suid).
129 Thanks to Philippe Troin <phil@fifi.org> for the patch.
131 13. Fixed the 'S' command handling in the rmt client part.
132 Thanks to Philippe Troin <phil@fifi.org> for the patch.
134 14. Modified the end-of-tape script handling to print out statistics
135 (and stop the timer) before launching the eot script. Also, the eot
136 script does not get run anymore when using -M (which makes sense) or
137 when multiple tapes are listed on the command line
138 (-f tape0,tape1,tapen) (which also makes sense).
139 Thanks to Philippe Troin <phil@fifi.org> for the patch.
141 15. Relicensed dump/restore under the 'revised' BSD license, as per
142 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
144 16. Added LZO compression to dump. This new compression method has
145 the advantage of being super fast, thus not killing tape streaming
146 on slow machines. Thanks to Helmut Jarausch
147 <jarausch@igpm.rwth-aachen.de> for the patch and to
148 Markus Oberhumer <markus@oberhumer.com> for giving special permission
149 to include his miniLZO project (GPL licensed) in dump/restore.
151 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
152 <ant@notatla.demon.co.uk> for reporting the bugs.
154 18. Added a special rmt version which can do encryption when writing
155 to tape. Read examples/encrypted_rmt/README for details on
156 how to enable and configure it. Thanks to Ken Lalonde
157 <ken@globalremit.com> for the patch.
159 19. Made dump work with 2.5 kernel end of tape early warning semantics.
160 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
162 20. Fixed a bug which caused dump -w|-W not to work anymore, because
163 the fs_freq and fs_passno fields in /etc/mtab are always set
164 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
167 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
168 =======================================================================
170 1. Added a note in the restore man page clarifying the question
171 'set the permissions on the current directory ?' asked by
172 restore at the end of treatment in -i and -x modes.
174 2. Fixed the endianess issues when reading compressed tapes.
175 Thanks to Dark Force <daq4th@users.sourceforge.net> for
176 reporting this bug and providing test cases.
178 3. Fixed the "ACL won't be dumped" warning message (which showed
179 an extra, unrelated error message). Thanks to Dragan Krnic
180 <dkrnic@lycos.com> for reporting this bug.
182 4. Made dump look first into /etc/mtab, then into /etc/fstab
183 when searching for filesystem paths. Also fixed some problems
184 caused by binding mounts or multiple block device mounts.
185 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
186 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
187 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
188 and #160305, Sourceforge bugs #618699 and #679832).
190 5. Made dump's -I option accept the value '0' meaning all the
191 read errors will be ignored. This can be useful when running
192 dump from unattended sessions (like cron jobs). Thanks to
193 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
195 6. Fixed the output of dump to indicate 'blocks' instead of
196 'tape blocks' in the various messages (blocks are always
197 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
198 made it clearly print the current blocksize at the start of
199 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
202 7. Made rmt understand long (largefiles) seeks.
204 8. Fixed build with very old versions of libext2fs, where
205 EXT2_FT_* constants were undefined.
207 9. Made dump accept the dumpdates path on the command line
208 (-D file option) instead of using only the hardcoded one.
209 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
212 10. Enabled rmt, LFS, readline, QFA options by default in
213 ./configure. Updated the configure process (new versions
214 of config.guess, config.sub etc).
216 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
217 =======================================================================
219 1. Changed dump to use fcntl(F_SETLK) style locking instead
220 of flock() when locking the dumpdates file. With the old
221 locking scheme, a local user having read rights on the
222 dumpdates file could be able to do a Denial of Service attack
223 on dump. In order to lock the dumpdates file with the new
224 scheme, the user would need to have write access on the file.
225 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
226 reporting the bug (originally a bugtraq post).
228 2. Fixed interactive 'ls' which caused spurious errors warnings
229 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
230 <jorgen_ostling@users.sourceforge.net> for reporting this
233 3. Fixed dump's estimate when dealing with sparse inodes.
235 4. Modified dump to allow setting a blocksize bigger than 32kB
236 (raised the limit to 1024kB), because newer hardware needs
237 this for proper operation. Thanks to Dirk Traenapp
238 <dtraenapp@users.sourceforge.net> for reporting this.
240 5. Fixed a bug causing Dump to stop and report an error if an
241 inode number in the exclude file was followed by some amount
242 of whitespace. Thanks to Jeffrey Sofferin
243 <sofferin@users.sourceforge.net> for reporting this bug.
245 6. Fixed a bug which caused restore, in some particular cases,
246 to ask some 'scary' questions and leave a bunch of RSTTMP
247 directories behind when restoring incremental tapes. Thanks
248 to Philippe Troin <phil@fifi.org> for reporting this bug and
249 providing the test cases.
251 7. Changed the wording when inodes are excluded from dump:
252 replaced 'Added inode 7 to exclude list' with
253 'Excluding inode 7 (resize inode) from dump', as suggested
254 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
256 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
257 ===================================================================
259 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
260 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
261 <eros@lamel.bo.cnr.it> for reporting the bug.
263 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
264 ===================================================================
266 1. Made dump print out the ext2 logical block number in case of a read
267 error, which can be given as an argument to debugfs' ncheck command,
268 in order to find out the affected inode. Added note about this
269 usage in dump's man page.
271 2. Fixed a problem in restore when reading tapes written on big
272 endian machines with very old versions of dump. The patch was
273 contributed by George Helffrich <george@geology.bristol.ac.uk>.
275 3. Fixed the tape length calculation when using large tapes
276 and compression. Thanks to Georg Lippold
277 <g_lippold@sourceforge.net> for reporting the bug.
279 4. Added a new set of examples in dump_on_cd_2 directory, based
280 on dump_on_cd examples but somewhat enhanced, supporting DVD
281 media, and localized in english and german. Thanks to
282 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
284 5. Made dump save 32 bit UID/GID. Internally, this was achieved
285 by switching from the old BSD inode format to the new BSD
286 inode format, which means that the tape format was changed.
287 However, since all restore versions out there should
288 transparently support both inode formats, the change should
289 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
292 6. Fixed a lot of warnings in the code shown when compiling
293 with 'gcc -W'. Thanks to Matthias Andree
294 <matthias.andree@stud.uni-dortmund.de> for reporting this.
296 7. Fixed a small markup bug in the dump man page. Thanks to
297 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
300 8. Rewrote entirely the man pages using the tmac.an macro
301 package (Linux man page format) instead of the original BSD
302 format. They should be now cleaner and easier to modify.
304 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
305 ==================================================================
307 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
308 non Linux clients were misinterpreted. The description of the problem
309 (incompatible numbering in Linux mtio opcodes) is documented at
310 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
311 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
312 providing an excellent, cross-platform replacement for rmt in his
315 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
316 which caused restore to fail when the inode maps were not entirely
317 contained on the first volume (when using really small volumes or
318 when dumping a huge number of inodes).
320 3. Fixed a problem in dump, where files in subdirectories of directories
321 that have the nodump flag set (or being excluded with -e/-E) were
322 sometimes incorrectly dumped (instead of being excluded). The original
323 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
324 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
325 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
326 help testing the patch.
328 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
329 which makes one able to pipe the output of dump, by the net, to
330 a remote CD-burner server.
332 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
333 and use GNU's symbolic syntax over rmt instead of numerical values
334 to assure multiple platform compatibility.
336 6. Documented the -d option in restore.
338 7. Added a -v (verbose) mode to dump. For now it just prints the number
339 of the inode being dumped, but this could evolve in future versions
340 to include interesting debugging output.
342 8. Added a -o flag to restore, which automatically restores the current
343 directory permissions in -i or -x mode, without asking the operator
344 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
345 and Peter Samuel <peters@e-smith.com>.
347 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
348 ====================================================================
350 1. Fixed a bug in the QFA feature which could have caused
351 a bad tape positionning on restore (causing extra delays in
352 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
354 2. Added a small note in the dump man page specifying that
355 there should be no white space between the option letter and
356 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
358 3. Made restore work with older versions of the readline library,
359 by checking in configure for several extended symbols. Restore
360 can now be compiled with a readline as old as the 2.0 release
361 (though it may be a good idea to upgrade it to a more recent
362 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
363 reporting the build failures.
365 4. Fixed a performance problem with the QFA file creation in
366 dump, which made unnecessary seeks on the tape slowing down
367 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
368 reporting this issue.
370 5. Removed the inclusion of some kernel headers in the dump
371 source, which prevented the compile in some kernel/glibc
372 headers/architecture combination. Thanks to Bdale Garbee
373 <bdale@gag.com> for reporting the bug.
375 6. Added the appropriate error message when dump fails to
376 open the output file for writing. Thanks to Amith Varghese
377 <amithv@yahoo.com> for reporting this bug.
379 7. Made restore able to understand large Solaris ufsdump tapes
380 (containing inodes bigger than 4194304). Sun have introduced
381 an "extension" to the dump tape format when dealing with
382 those inodes, which was uncorrectly handled by Linux restore.
383 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
384 providing a test case.
386 8. Added the -m parameter to dump which optimises the output for
387 inodes having been changed but not modified since the last dump
388 ('changed' and 'modified' have the meaning defined in stat(2)).
389 For those inodes, dump will save only the metadata, instead of
390 saving the entire inode contents. Inodes which are either
391 directories or have been modified since the last dump are saved
392 in a regular way. Uses of this flag must be consistent, meaning
393 that either every dump in an incremental dump set have the flag,
396 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
397 =======================================================================
399 1. Fixed behaviour of dump when exceeding resource limits
402 2. Added the -L flag to restore to allow the user to specify a
403 maximal allowed number of miscompares when using restore
404 with the -C option to check the backup.
406 3. Detailed the manual entry for the -N option of restore.
408 4. Added the -a flag to restore to make able doing unattended
409 restores in -i or -x mode (automatically walks through the
410 multiple dump volumes).
412 5. Extended the QFA mode to work with local files and/or
413 remote tapes and files. This way, restore can know in advance
414 the tape number and the offset for the inodes to extract and
415 can minimize the extraction time by seeking directly to the
418 6. Added the -A <archive> option to both dump and restore,
419 which makes dump to archive a dump table-of-contents in
420 the specified file to be used by restore to determine
421 whether a file is in the dump file that is being restored.
422 (the archive file syntax is also compatible with the
423 Solaris ufsdump generated one).
425 7. Small fix in restore making it able to read some (broken ?)
426 Solaris ufsdump tapes.
428 8. Fixed dump to correctly recognise the root filesystem when using
429 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
430 for reporting this bug.
432 9. Added the -P <file> option to restore to create a
433 Quick File Access file from an already made dump. Patch
434 contributed by Uwe Gohlke <uwe@ugsoft.de>.
436 10. Made restore compile and run on Solaris, making it a
437 possible replacement for the standard ufsrestore. Port was
438 contributed by Uwe Gohlke <uwe@ugsoft.de>.
440 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
441 =====================================================================
443 1. Added a set of backup scripts from Eugenio Diaz
444 <getnito@yahoo.com> in the examples section. It features
445 automatic (cron based) full and incremental dumping of
446 several filesystems on a separate filesystem.
448 2. Fixed a off-by-one miscalculation which disabled dumping
449 a one letter subdirectory. Thanks to Chris Siebenmann
450 <cks@utcc.utoronto.ca> for reporting the bug.
452 3. Fixed several restore bugs occuring when trying to
453 restore some missing files on the tape. Thanks to Chris
454 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
456 4. Fixed --with-ldopts configure argument passing, installing from
457 a separate object directory, makefile cleanups contributed
458 by <splite@purdue.edu>.
460 5. Fix a bug which could caused, in some conditions, the highest
461 number inode of a filesystem, to not be dumped. Many thanks
462 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
465 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
466 =======================================================================
468 1. Added a mini howto from Patrick Walsh in the examples
471 2. Minor man pages syntax corrections. Thanks to
472 Chris Danis <screechco@home.com> for reporting the bugs.
474 3. Added a script from David B. Peterson <dave@toppledwagon.com>
475 to the examples section. It features dumping several
476 filesystems to a remote tape drive upon ssh.
478 4. Added a patch provided by Richard Jones <rich@annexia.org>
479 which allows BRADEMAX (number of read errors tolerated by
480 dump) to be adjusted using the -I option.
482 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
483 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
486 6. Add the -l option to restore to specify if, when doing a
487 remote restore, the file used to access the backup is a
488 regular file (the defaults being a tape drive). Restore needs
489 to know this information when reading a remote compressed
490 dump. Previously, this information was autodetected, but
491 the autodetection code fails (with ioctl: Inappropriate ioctl
492 for device) when using a non Linux remote box. Thanks to
493 many users and especially to Eros Albertazzi
494 <eros@lamel.bo.cnr.it> for reporting this.
496 7. Found a workaroung for the dump deadlock problem (3 childs
497 stuck in pause(), father in read()). The workaround seems
498 to work for me and several beta-testers. If it doesn't work
499 for you, please report back.
501 8. Updated the RPM spec file (BuildPrereq, URL etc).
503 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
504 ========================================================================
506 1. Fixed the permissions of a newly created QFA file by dump.
508 2. Cleaned up the source of dump (the external variables
509 definition was a complete mess, making possible to have
512 3. Fixed restore to use the full tape volume path when doing
513 a compare (since it changes the working directory to the
514 filesystem being compared in the process).
516 4. Added the -q option to dump which makes dump abort
517 whenever it needs operator attention. It should be
518 easier to use dump in scripts with this option.
520 5. Detect the use of incompatible options to dump and
521 refuse them (like -a and -B options together).
523 6. Added bzip2 compression to dump/restore (use option -j level
524 to select it). Note that you will need a restore version
525 >= 0.4b24 in order to restore a bzip2 compressed dump.
526 The same warning as for the zlib compression applies:
527 the tape format of a bzip2 dump is not compatible with the
528 original BSD tape format.
530 7. Fixed a overflow problem in dump corrupting the dump when
531 very large files were encountered. Thanks to Vladimir Nadvornik
534 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
535 kernel buffer/page cache before starting the dump, helping
536 a bit those who use dump on mounted filesystems. Thanks to
537 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
540 9. Updated the RPM spec file following the RedHat changes
541 (dynamically linked binaries now in /usr/sbin etc).
543 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
544 which enables restore to recognise multi volume compressed dumps
545 done on CD. Included his scripts for dump (which pipe the dump
546 output directly into cdrecord) and restore. There is now
547 possible to to backups to CD on the fly!
549 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
550 ===================================================================
552 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
553 Marcus Meissner (Caldera International Security Dept.).
555 2. Implement the Sun rmt extended protocol. Patch submitted
556 by Ian Gordon <iangordon@users.sourceforge.net>.
558 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
559 the linux kernel header. This ensures that dump always has the
560 latest version of this file. Patch submitted by
561 Andreas Dilger <adilger@turbolinux.com>.
563 4. Report any filesystem present in either /etc/fstab with a
564 positive passno or /etc/dumpdates in dump -w output.
565 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
567 5. Fixed the looping problem in dump introduced in the
570 6. Changed the -B option of dump to limit the size of
571 _compressed_ output per volume if compression is on.
572 Patch contributed by Helmut Jarausch
573 <jarausch@igpm.rwth-aachen.de>. Note however that, since
574 it is impossible to predict the size of the compressed
575 data before doing the compression, the -B limit is a bit
578 7. Fixed a bug in reading the operator typed file/tape path for
579 the next volume in restore.
581 8. Implemented a "-F script" option to restore which permits the
582 user to specify a script which will be launched at the
583 beginning of each tape, useful for automatic programming of
584 tape changers for example. See the restore man page for the
585 script parameters and return codes.
587 9. Small fix for the QFA routines provided by Uwe Gohlke
588 <uwe@ugsoft.de>, and some recommendations for QFA uses in
591 10. Fixed the multivolume restoring where making a mistake
592 to the 'Mount next tape' prompt caused several blocks to
595 11. Enhanced the -e option of dump to take as a parameter a
596 comma separated list of inode numbers.
598 12. Added the -E option to dump which specify a file containing
599 inode numbers to exclude from the dump.
601 13. Fixed the compressed multi-volume dump + restore.
603 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
604 ==================================================================
606 1. Made dump report the number of blocks dumped per volume.
607 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
609 2. Fix a bug in dump where waiting too much at the 'change volumes'
610 question caused the volume to be rewritten. Thanks to
611 Graham Reed <greed@users.sourceforge.net> for reporting the
612 bug and providing a patch.
614 3. Added a compression option to dump, contributed by Jerry
615 Peters <gapeters@worldnet.att.net>.
617 WARNING: the compression works only on files/pipes and
618 drives supporting variable block size.
620 WARNING2: tapes created using the compression feature are
621 incompatible with the standard dump tape format, and a
622 version of restore >= 0.4b22 will be needed for extraction.
624 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
625 architectures. Thanks to Paul Slootman <paul@debian.org> for
626 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
629 5. Many cleanups (CPP defines, const char warnings, check of
630 ext2fs COMPAT flags, time_t cleanups, added libext2 version
631 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
633 6. Made --prefix option work in configure. All the install path
634 are now based on the configure parameters.
636 7. Added the Quick File Access mode in dump/restore, contributed
637 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
638 a file tape position for each inode, and this file is used by
639 restore (if called with parameter Q and the filename)
640 to directly position the tape at the file restore is currently
641 working on. This saves hours when restoring single files from
642 large backups, saves the tapes and the drive's head. Use
643 --enable-qfa option of configure to compile in the QFA support.
645 8. Added the possibility to dump several files and directories
646 in a single invocation of dump. Thanks to Uwe Gohlke
647 <uwe@ugsoft.de> for implementing this option.
649 9. Fixed the dumping and restoring of files with holes
650 (files ending with holes didn't get dumped or restored
653 10. Fixed a socket descriptor leak in dump, which leaved opened
654 3 file descriptors per dump process (and there is one dump
657 11. Fixed dump large file system support, by explicit use of
658 open64/lseek64/etc functions (explicit use needed because
659 e2fsprogs libraries don't behave well when compiled with
660 FILE_OFFSET_BITS=64).
662 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
663 ======================================================================
665 1. Fixed some bugs in the dump -w|-W logic introduced by
666 the previous version. Thanks to Andreas Dilger
667 <adilger@turbolinux.com> for his help on this one.
669 2. Fixed again a compilation problem when using old e2fs
670 headers (filesystem label related). Thanks to many users
671 who reported this stupid error.
673 3. Fixed a build problem on old lib5 based systems dealing with
674 _PATH_MNTTAB being undefined. Thanks to John Adams
675 <johna@onevista.com> for reporting the bug.
677 4. Improved the error detection in restore when creating
678 the temporary files in TMPDIR. Now restore will corectly
679 report a 'no space left on device' error instead of
680 strange errors which could imply an archive corruption.
681 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
682 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
684 5. Added the throughput information in dump's progression
685 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
688 6. Use libext2fs's inode scanning routines, which are particularly
689 robust when dealing with errors (especially when having some
690 bad blocks on the filesystem). Many thanks to Colin
691 <colin@horizon.com> for reporting the bug, investigating
692 the issues, finding a workaround, writing the patch and
693 fully testing it... (of course, if this patch will break
694 anything, he is to blame for :-)).
696 7. Made dump and restore LFS aware. Dump can dump a filesystem
697 containing large files, generate a large file on output and
698 restore can restore them. This feature is not enabled by
699 default, use --enable-largefile option of configure to enable
700 it (you need to have a LFS aware glibc though). Thanks to
701 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
702 and to Theodore T'so <tytso@valinux.com> for his always
705 8. Made dump ask upon a tape write error if it should rewrite
706 the current volume (assume this is a bad tape) or if it should
707 assume an end-of-tape condition (useful for tape drives which
708 behaves badly at the end of the tape). Thanks to Andreas
709 Dilger <adilger@turbolinux.com> for the suggestion.
711 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
712 =======================================================================
714 1. Fixed a small compilation problem due to a change
715 in the definintion of the struct sigaction in
716 glibc 2.0 / libc5. Thanks to Gunther Schlegel
717 <schlegel@riege.de> for reporting the bug and to
718 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
721 2. Modified the label and uuid analysis in order to be
722 self-contained (independant of kernel/libc headers). This
723 should fix the compile with older kernel/libc headers and
724 will preserve the functionality. Thanks to Bernhard Erdmann
725 <bernhard.erdmann@gmx.de> for reporting the bug.
727 3. The 'exclude inode' option, if applied to a directory
728 inode, excludes now correctly all the leaves of this
729 directory. Thanks to John R. Dennison
730 <gerdesas@users.sourceforge.net> for reporting the bug.
732 4. Fixed the '-e' option to disable the possibility
733 to exclude the root inode (which causes the dumps to
734 be unreadable by restore). Prevented array overflow
735 when multiple -e options are used.
737 5. Fixed dump to correctly interpret a filesystem argument
738 which is a mountpoint and it is not an absolute path
739 (as specified in the fstab). Thanks to Bernhard R. Erdmann
740 <be@berdmann.de> for reporting the bug.
742 6. Made dump able to backup files larger than 2 GB. Note that
743 dump still doesn't cope with files larger than 4 GB.
745 7. Restore the real uid and gid before invoking an external
746 RSH program (big hole when dump or restore is suid root!).
748 8. Get the values for the default tape device and the location
749 of fstab file from the system headers. Thanks to
750 Andreas Dilger <adilger@turbolinux.com> for the patch.
752 9. Made dump -w|-W report all recognized filesystems
753 present in either /etc/fstab or /etc/dumpdates, and present
754 the list in the same order as in fstab file. Thanks
755 to Andreas Dilger <adilger@turbolinux.com> for the patch.
757 10. Made dump's -a (automatic end of tape detection) the
758 default. Specifying one of -B, -c, -d or -s options will
759 override the EOM detection. Thanks to Andreas Dilger
760 <adilger@turbolinux.com> for the patch.
762 11. Save the ext2 filesystem label into the dump volume label.
763 Specifying a volume label on the command line (-L option)
764 will override this feature. Thanks to Andreas Dilger
765 <adilger@turbolinux.com> for the patch.
767 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
768 =====================================================================
770 1. Fixed the signal handling in dump (which I broke in 0.4b17)
771 which was causing several strange dump failures (dump
772 hanged or segmentation faults etc).
774 2. Specified the default blocksize in the dump man page.
776 3. Changed two info messages of restore to be written on stdout
777 instead of stderr in order to leave stderr only for errors
778 or warnings. Thanks to Stephen Atwell
779 <satwell@urbana.css.mot.com> for the suggestion.
781 4. Corrected an off by one calculation which prevented
782 dumping a directory having a 1 character name length.
783 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
784 for reporting the bug.
786 5. Reinforce dump in order to allow only level 0 and no
787 -u option when dumping a subdirectory, and document
788 this in the man page. Thanks to Bernhard Erdmann
789 <bernhard.erdmann@gmx.de> for reporting the bug.
791 6. Fixed a small harmless bug in restore which caused
792 in some conditions hard links to be restored several
793 times (therefore generation some warning messages).
794 Thanks to Kenneth Porter <shiva@well.com> for
797 7. Updated the RPM spec file to the latest RedHat version,
798 providing FHS packaging and other cosmetic changes.
799 You will need RPM version >= 3.0.5 in order to build the RPM.
801 8. Updated the configure script to check for libtermcap
802 before checking for libreadline, because we need this
803 library in order to compile the readline support.
805 9. Made dump understand the LABEL= and UUID= notation
806 both in /etc/fstab and on the command line. Note that
807 you will need the /proc filesystem in order to use
808 these notations. Thanks to Erik Troan <ewt@redhat.com>
809 for providing the patch.
811 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
812 ===================================================================
814 1. Fixed a potential buffer overflow in restore. Thanks
815 to Stan Bubrouski <satan@fastdial.net> for reporting
818 2. Fixed a readline-related bug which prevented
819 'cat DUMPFILE | restore -i -f -' from working. Thanks
820 to Charles Karney <karney@users.sourceforge.net>
823 3. Changed a few "panic" into "exit", causing restore to
824 be more stable against some attacks (like the last one
825 reported on Bugtraq, although the last version of restore
826 was not vulnerable - just dumped core). Thanks to
827 Andreas Hasenack <andreas@conectiva.com.br> for reporting
830 4. Removed the suid-root bit on dump and restore in the
831 default build (and generated RPMs). It should be safer
832 now. Users who need the suid-root capabilities in order
833 to make network backups should read first the man page
834 of dump and enable the suid bit manually.
836 5. Added -ltermcap to the compile parameters for restore
837 when using readline support, in order to make the compile
838 process work on some systems (SuSE ?). Thanks to
839 Patrik Schindler <poc@pocnet.net> for reporting the bug.
841 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
842 ====================================================================
844 1. The -F script is called now *only* at the end of a tape,
845 not at the end of the dump. Thanks to Christian Haul
846 <haul@informatik.tu-darmstadt.de> for the bug report.
848 Normally, the device name and the current volume number
849 are passed on the command line of the script. However,
850 if you want the old style script (with no arguments
851 passed on the command line), you can enable it in
852 configure with the --enable-oldstylefscript.
854 2. Use posix signal handling to preserve dump functionality
855 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
858 3. Made the exit code of restore in case of a 'C'ompare
859 command reflect the result of the compare. An exit status
860 of 0 means the dump archive is correct, 1 means tape errors,
861 2 means that some files were modified. Thanks to Kenneth Porter
862 <shiva@well.com> for the suggestion.
864 4. Made (finally) quotes work in interactive restore.
866 5. Small fixes in order to allow dump to compile with a
867 really old e2fsprogs version. Thanks to Ian Zimmerman
868 <itz@speakeasy.org> for the bug report.
870 6. Add GNU readline capabilities to interactive restore.
871 Use configure's --enable-readline flag to enable this feature.
872 Thanks to Patrik Schindler <poc@pocnet.net> for the
875 7. Do the compare on the fly in restore 'C' mode (this will
876 allow not to exhaust the available /tmp space when
877 ccmparing large files). Thanks to Kenneth Porter
878 <shiva@well.com> for the suggestion.
880 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
881 ====================================================================
883 1. Fixed some several duplicate 'DUMP: DUMP:' in the
886 2. Corrected the estimation of blocks to dump. Note that
887 this is still wrong for large directory inodes, due
888 to the size of a BSD directory entry on the tape
889 (estimation is based on the size of the ext2 directory,
890 which is smaller because it doesn't contain the null
891 character at the end).
893 3. Made dump report the total number of MB written to
894 tape at the end of run. Thanks to W. Reilly Cooley
895 <wcooley@nakedape.cc> for the patch.
897 4. Added the -X option to restore giving the possibility
898 to read the names of the files to be extracted/listed
899 from a text file (in addition of the command line).
900 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
903 5. Added the device name and the current volume number
904 as arguments to the end of tape script (dump -F option).
906 6. Made the multi-volume dump work again (after having
907 broken it in 0.4b15).
909 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
910 ===================================================================
912 1. Added a prompt command in interactive restore mode. Thanks
913 to Andreas Dilger <adilger@home.com> for the patch.
915 2. Fixed a buffer overflow problem in dump (caused by
916 not checking the size of the filesystem parameter).
917 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
918 reporting this on Bugtraq (and to several dump users
919 who forwarded me his mail).
921 3. Added the '-F script' option to dump in order to
922 launch a script at the end of each tape (to be used
923 with a tape changer, or to notify the sysadmin by
926 4. Fixed a bug in restore compare code caused by the changes
929 5. Fixed the treatment of options using the old BSD syntax
930 in both dump and restore.
932 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
933 =======================================================================
935 1. Fixed a bug in dump which may have caused invalid deleted
936 directories to be dumped out if they were deleted after the
937 mapping pass. This could occure on active filesystem and lead
938 to heap corruption (causing dump malfunction in many possible ways).
939 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
940 bug and submitting the patch.
942 2. Fixed the handling of the filesystem parameter in dump. A
943 '/mnt/disk' parameter caused the disk contents to be dumped,
944 but a '/mnt/disk/' parameter caused the mountpoint directory
945 to be dumped (generally an empty directory).
947 3. Improved the output of dump in order to tell which directory
948 it is currently dumping (when dumping a subtree).
950 4. Added the '-e' exclude inode option to dump. Thanks to
951 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
953 5. Added a REPORTING-BUGS file in order to provide a guide
954 on how to correctly report a bug in dump/restore.
956 6. Fixed a restore problem when restoring a hard link to an inode
957 having the immutable or append-only attribute set. Thanks to
958 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
960 7. Fixed a compatibility problem between dumps made on little
961 endian machines (the format was correct) and big endian
962 machines (the format was incorrect). This fix break the
963 compatibility with the older dumps made on big endian
964 machines (sparc, m86k, ppc etc). For the first time in
965 linux dump's history (I believe), the dumps made by *BSD,
966 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
967 so interchangeable. Thanks to Rob Cermak
968 <cermak@ahab.rutgers.edu> for submitting the bug and
969 helping me test the fix.
971 8. Fixed the way dump reports the remaining percent/time, if
972 the number of blocks actually dumped exceeds the estimated
973 number of blocks. Thanks to Jean-Paul van der Jagt
974 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
976 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
977 ======================================================================
979 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
980 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
982 2. Removed the requirement to build the RPM as root from the
983 spec file. Thanks to Christian Weisgerber
984 <naddy@mips.rhein-neckar.de> for submitting this.
986 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
987 causing dump to block when dumping really huge filesystems.
988 Many thanks to Patrik Schindler <poc@pocnet.net> for
989 helping me find this bug.
991 4. Fixed the treatment for an interrupt signal when dump access
992 the remote tape through RSH. Thanks to Christian Weisgerber
993 <naddy@mips.rhein-neckar.de> for providing the patch.
995 5. Fixed a bug which was causing dump/restore to display
996 garbage characters instead of the remote host name.
998 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
999 =====================================================================
1001 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1002 <kukuk@suse.de> for submitting the patch.
1004 2. Fix for the exit code when using the size estimate option of
1005 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1006 submitting the patch.
1008 3. Handle EINTR in atomical reads/writes in dump, which was causing
1009 dump to fail on some systems. Thanks to Eric Jergensen
1010 <eric@dvns.com> for reporting the bug and submitting the patch.
1012 4. Handle more than 16 characters for the device names in dumpdates.
1013 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1014 tracking down the problem and proposing the solution.
1016 5. Fixed a bug in dump which prevented the creation of the
1017 dumpdates file when doing a 0-level dump without already
1018 having a dumpdates file. Thanks to Patrik Schindler
1019 <poc@pocnet.net> for reporting the bug.
1021 6. Changed the way dump 'S' flag reports the size estimate
1022 from number of blocks into bytes (making it compatible
1023 with the Solaris version, and simplifying things for
1024 amanda users). Thanks to Jason L Tibbitts III
1025 <tibbs@math.uh.edu> for reporting the bug.
1027 7. Fixed a compatibility problem in linux/alpha dump tape format.
1028 Now the linux/alpha dump are (again) compatible with the
1029 other dump formats. But this breaks compatibility with
1030 older dumps made on alpha. Thanks to Mike Tibor
1031 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1033 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1034 ======================================================================
1036 1. Added a '--enable-kerberos' to configure.
1038 2. Added a 'S' option to dump which determines the amount of space
1039 that is needed to perform the dump without actually doing it, similar
1040 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1041 <cermak@ahab.rutgers.edu>.
1043 3. Added a 'M' multi-volume option to dump and restore which enables
1044 dumping to multiple files (useful when dumping to an ext2
1045 partition to make several dump files in order to bypass the 2GB
1046 file size limitation). The 'f' argument is treated as a prefix and
1047 the output files will be named <prefix>001, <prefix>002 etc. With
1048 the 'M' flag, restore automatically selects the right file without
1049 asking to enter a new tape each time.
1051 4. Fixed a memory leak which was causing dump to grow very big
1052 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1053 Fearon <jasonf@netrider.org.au> for reporting the bug.
1055 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1056 ======================================================================
1058 1. Make configure test if the system glob routines support
1059 extended syntax (ALTDIRFUNC). If not, use the internal glob
1060 routines instead of system ones. Thanks to Bernhard Sadlowski
1061 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1062 and helping me resolve this and other minor libc5 compiling
1065 2. Fix a problem when dumping a ext2fs with the 'filetype'
1066 feature enabled. Thanks to Patrick J. LoPresti
1067 <patl@cag.lcs.mit.edu> for reporting the bug and to
1068 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1070 3. Made the nodump flag work on directories. A directory which
1071 has the nodump flag gets never dumped, regardless of its
1074 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1075 which allows dump on an active ext3 filesystem. However, this
1076 is a "quick and dirty" patch which enables backup of an ext3
1077 filesystem through the ext2 compatibility (by ignoring the
1078 NEEDS_RECOVERY bit). The journal file is not recognized and
1079 it is dumped (it should not).
1081 5. Test the superblock compatibility flags when dumping, in order
1082 to be sure that we know how to deal with specific features.
1084 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1085 ====================================================================
1087 1. Use lchown instead of chown, fixing a possible security problem
1088 when restoring symlinks (a malicious user could use this
1089 to deliberately corrupt the ownership of important system files).
1090 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1091 this and providing the patch.
1093 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1094 ====================================================================
1096 1. Put dump sources under CVS, added Id tags in all files so
1097 one can use 'ident' on binary files.
1099 2. Added the dump/restore version in the usage text so one can
1100 easily verify the version he is using.
1102 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1103 a va_start/va_end problem on linux-ppc (always call va_start
1104 va_end in pairs each time we use a vararg function).
1106 4. Added again the DT_* constants because old libc does not
1107 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1108 for submitting the bug report.
1110 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1111 this should enable dumping big (huge) filesystems.
1113 6. Added the RSH environment variable in order to be able to
1114 use a rsh replacement like ssh when doing remote backups (and
1115 bypass the security limitations of rcmd). Now you can do remote
1116 backups without being root (or making dump setuid root).
1118 7. Modified again the way dumpdates works. For incremental dumps,
1119 we need to read dumpdates even if we are not using 'u' option.
1120 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1123 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1124 ===================================================================
1126 1. Removed the 'k' flag from the restore 'about' text if kerberos
1127 was not compiled in.
1129 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1130 to them (fsetflags takes a char*, setflags an open fd!).
1132 3. (f)setflags is called only if the flags aren't empty. If the
1133 file is a special file, a warning is printed, because changing
1134 flags implies opening the device. Normally, a special file
1135 should not have any flag... (Debian bug #29775, patch provided
1136 by Abhijit Dasgupta <abhijit@ans.net>).
1138 4. Made possible to dump a file system not mentioned in /etc/fstab.
1139 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1141 5. Changed the default behaviour to not create dumpdates
1142 unless 'u' option is specified. Removed the old "debian-patch"
1143 which provided the same thing. (Debian bug #38136, #33818).
1145 6. Removed all those dump*announce, since they were getting old...
1147 7. Added warning messages if dumpdates does not exist and
1148 when an inferior level dump does not exist (except for a level 0
1151 8. Debugged the glob calls in interactive mode: restore used a
1152 dirent struct which was different from the /usr/include/dirent.h
1153 one (this used to work, is it a glibc2 change?), so none of the
1154 compat glob (which used /usr/include/dirent.h) or the system glob
1155 worked. Restore use now the system dirent (and the system
1156 DT_* constants), which are compatible with BSD ones.
1158 9. Added a configure flag (--with-dumpdatespath) to specify
1159 the location of dumpdates file. By default, it is
1162 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1163 included the current date/version in man pages.
1165 11. Corrected the estimation of remaining time when
1166 the operator doesn't change the tapes quickly enough. This
1167 was an old bug, I thought I corrected it, and discovered
1168 that in fact it was corrected in two different places, so
1169 the results canceled each other...
1171 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1172 ===================================================================
1174 1. Integrated multiple patches from RedHat, Debian and SuSE:
1176 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1178 - several fixes in the man pages.
1179 - update the default tape device to /dev/st0.
1180 - many updates for Linux Alpha (byte ordering, size_t etc).
1182 - use environment variable for TMPDIR (instead of /tmp).
1183 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1184 - workaround egcs bug (RedHat bugs #4281 and #2989).
1185 - wire $(OPT) throughout Makefile's.
1187 2. Upgrade the dump revision to 1, making possible to dump filesystems
1188 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1190 3. Fix some compile warnings, prototype all functions.
1192 4. Use glibc err/glob instead of internal compatibility
1193 routines (only if available).
1195 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1196 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1198 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1199 ======================================================================
1201 1. Integrated the changes from FreeBSD-3.1-RELEASE
1202 (mostly bug fixes, buffer overruns, dump has now an "automatic
1203 tape length calculation" flag, dump/restore can use kerberos now
1204 (this is NOT tested), use environment variables for TAPE and
1207 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1209 3. Corrected a bug in restore when using 'C' option with multi-volumes
1210 tapes (files splited accros two tapes give "size changed" errors
1213 4. Corrected the long standing bug when dumping multiple tapes.
1214 This works for me, needs further testing.
1216 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1217 ====================================================================
1219 1. Dump now runs correctly on kernels 2.1.x
1220 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1222 Changes between versions 0.4b2 and 0.4b3
1223 ========================================
1225 1. Use realpath() if available
1227 2. Report statistics
1229 Changes between versions 0.4b1 and 0.4b2
1230 ========================================
1232 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1235 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1237 3. Fixed configure.in to correctly handle --enable-rmt
1239 Changes between versions 0.3 and 0.4b1
1240 ======================================
1242 1. Integrated the changes from 4.4BSD-Lite2
1244 2. Integrated the patches from Debian and Red Hat
1246 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1248 4. Changed dump to use the Ext2fs library to get block addresses. This
1249 should solve the endianness problem on SparcLinux.
1251 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1252 distribution's one) to use autoconf
1254 6. Fixed a few minor bugs
1256 Changes between versions 0.2e and 0.2f
1257 ======================================
1259 1. Added the creation of named pipes (fifos) in restore.
1261 2. Added the -N flag in the restore manual page.
1263 3. Added the file kernel.patch which contains the llseek() optimization
1264 patch for 1.2.x kernels.
1266 4. Fixed a bug in the restoration of symbolic links: owner and group were
1269 5. Integrated some changes from FreeBSD 2.2.
1271 6. Added a call to ftruncate() after restoring each file to restore
1272 correctly files ending by a hole.
1274 Changes between versions 0.2d and 0.2e
1275 ======================================
1277 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1278 with owner = root (0) and group = root/wheel/whatever (0).
1280 Changes between versions 0.2c and 0.2d
1281 ======================================
1283 1. Dump is now able to backup 2GB+ filesystems.
1285 2. Dump and restore can now be linked as static binaries.
1287 Changes between versions 0.2b and 0.2c
1288 ======================================
1290 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1292 Changes between versions 0.2a and 0.2b
1293 ======================================
1295 1. Really fixed the bug that I should have corrected in 0.2a.
1297 2. Enabled optimization again.
1299 Changes between versions 0.2 and 0.2a
1300 =====================================
1302 1. Disabled the optimization during compilation.
1304 Changes between versions 0.1 and 0.2
1305 ====================================
1307 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1308 the fs_type field (actually, I modified the file fstab.c to make it
1309 use the mntent functions).
1311 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1312 made by dump should be readable by the BSD restore and backups made
1313 by the BSD dump should be readable by restore. Unfortunately, this
1314 means that the dump format has changed between version 0.1 and version
1317 3. Dump is now able to backup a subtree, it is no longer limited to whole
1318 filesystems like the BSD version.
1320 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1323 Changes between versions 0.0 and 0.1
1324 ====================================
1326 1. Now create links rdump and rrestore during the `make install' step.
1328 2. Linux port specific bugs added to the manual pages
1330 3. Incorrect estimation of the number of tapes blocks fixed when doing
1331 incremental backups.
1333 4. Better ls-like format in restore in interactive mode.
