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 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
28 =======================================================================
30 1. Added a note in the dump man page saying that the default
31 blocksize can be 32 if -d is used with a high density argument.
32 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
35 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
36 LDFLAGS environment variables. Thanks to Arcady Genkin
37 <antipode@users.sourceforge.net> for reporting the bug.
39 3. Made -e/-E options of dump accept an unlimited number of inodes
40 to be excluded, rather than a hardcoded maximum. Thanks to
41 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
43 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
44 and -D_USE_BSD_SIGNAL defines in configure in order to solve
45 64bit build problems because quad_t is redifined with a
46 different signature. Thanks to Mike Harris <mharris@redhat.com>
47 for reporting this bug.
49 5. Made restore build on Solaris, making possible to
50 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
51 <uwe@ugsoft.de> for the patch.
53 6. Made an extension in the dump tape format capable of saving
54 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
55 wrote the extension and contributed the restore code back
56 into this codebase. The same extension mechanism will be
57 used in the future to save ACLs...
59 7. Made rmt work correctly with regard to QFA and local/remote
60 files and tapes. The remote access will however work only
61 when the dump provided rmt version is used. If you want to
62 use another rmt server, please do not use the QFA feature.
63 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
65 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
66 ====================================================================
68 1. Fixed the INSTALL file to reflect the actual install paths.
69 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
72 2. Fixed the configure script to only check for headers presence
73 instead of trying to compile them. This should fix issues
74 with old build environments. Thanks to Kari Lempiainen
75 <kari@funky.pp.fi> for reporting the bug.
77 3. Fixed restore to correctly ignore sockets when comparing
78 a dump (as socket cannot be properly restored anyway). Thanks
79 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
81 4. Fixed restore to correctly access the archive file (-A argument)
82 even when using a remote tape. Thanks to Fabrice Bellet
83 <fabrice@bellet.info> for reporting the bug.
85 5. Fixed (again) handling of long (largefile) seeks in rmt.
86 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
89 6. Fixed restore corner case when dealing with large block sizes
90 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
91 <fabrice@bellet.info> for reporting the bug.
93 7. Fixed a bug preventing dump to access a filesystem having
94 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
95 for reporting the bug.
97 8. Made dump store dump dates using explicit timezones, fixing a
98 problem with incremental dumps if the timezone is modified
99 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
100 the bug report and the patch.
102 9. Fixed a bug encountered when dumping individual files (not full
103 filesystems or directories) and dangling symbolic links happen
104 to be in the list of files. For as far as dump is concerned,
105 dangling symbolic links are allowed, and are dumped as is.
106 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
107 bug and providing the fix.
109 10. Fixed open and creation modes and permissions for QFA and
110 table-of-contents files in dump and restore. Thanks to
111 Philippe Troin <phil@fifi.org> for the patch.
113 11. Fixed the archive file descriptor handling enabling it to be 0.
114 This can happen in some cases when shell redirections are used.
115 Thanks to Philippe Troin <phil@fifi.org> for the patch.
117 12. Delayed the opening of archive file until after suid had been
118 dropped (fixing a possible security issue if dump is suid).
119 Thanks to Philippe Troin <phil@fifi.org> for the patch.
121 13. Fixed the 'S' command handling in the rmt client part.
122 Thanks to Philippe Troin <phil@fifi.org> for the patch.
124 14. Modified the end-of-tape script handling to print out statistics
125 (and stop the timer) before launching the eot script. Also, the eot
126 script does not get run anymore when using -M (which makes sense) or
127 when multiple tapes are listed on the command line
128 (-f tape0,tape1,tapen) (which also makes sense).
129 Thanks to Philippe Troin <phil@fifi.org> for the patch.
131 15. Relicensed dump/restore under the 'revised' BSD license, as per
132 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
134 16. Added LZO compression to dump. This new compression method has
135 the advantage of being super fast, thus not killing tape streaming
136 on slow machines. Thanks to Helmut Jarausch
137 <jarausch@igpm.rwth-aachen.de> for the patch and to
138 Markus Oberhumer <markus@oberhumer.com> for giving special permission
139 to include his miniLZO project (GPL licensed) in dump/restore.
141 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
142 <ant@notatla.demon.co.uk> for reporting the bugs.
144 18. Added a special rmt version which can do encryption when writing
145 to tape. Read examples/encrypted_rmt/README for details on
146 how to enable and configure it. Thanks to Ken Lalonde
147 <ken@globalremit.com> for the patch.
149 19. Made dump work with 2.5 kernel end of tape early warning semantics.
150 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
152 20. Fixed a bug which caused dump -w|-W not to work anymore, because
153 the fs_freq and fs_passno fields in /etc/mtab are always set
154 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
157 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
158 =======================================================================
160 1. Added a note in the restore man page clarifying the question
161 'set the permissions on the current directory ?' asked by
162 restore at the end of treatment in -i and -x modes.
164 2. Fixed the endianess issues when reading compressed tapes.
165 Thanks to Dark Force <daq4th@users.sourceforge.net> for
166 reporting this bug and providing test cases.
168 3. Fixed the "ACL won't be dumped" warning message (which showed
169 an extra, unrelated error message). Thanks to Dragan Krnic
170 <dkrnic@lycos.com> for reporting this bug.
172 4. Made dump look first into /etc/mtab, then into /etc/fstab
173 when searching for filesystem paths. Also fixed some problems
174 caused by binding mounts or multiple block device mounts.
175 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
176 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
177 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
178 and #160305, Sourceforge bugs #618699 and #679832).
180 5. Made dump's -I option accept the value '0' meaning all the
181 read errors will be ignored. This can be useful when running
182 dump from unattended sessions (like cron jobs). Thanks to
183 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
185 6. Fixed the output of dump to indicate 'blocks' instead of
186 'tape blocks' in the various messages (blocks are always
187 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
188 made it clearly print the current blocksize at the start of
189 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
192 7. Made rmt understand long (largefiles) seeks.
194 8. Fixed build with very old versions of libext2fs, where
195 EXT2_FT_* constants were undefined.
197 9. Made dump accept the dumpdates path on the command line
198 (-D file option) instead of using only the hardcoded one.
199 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
202 10. Enabled rmt, LFS, readline, QFA options by default in
203 ./configure. Updated the configure process (new versions
204 of config.guess, config.sub etc).
206 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
207 =======================================================================
209 1. Changed dump to use fcntl(F_SETLK) style locking instead
210 of flock() when locking the dumpdates file. With the old
211 locking scheme, a local user having read rights on the
212 dumpdates file could be able to do a Denial of Service attack
213 on dump. In order to lock the dumpdates file with the new
214 scheme, the user would need to have write access on the file.
215 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
216 reporting the bug (originally a bugtraq post).
218 2. Fixed interactive 'ls' which caused spurious errors warnings
219 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
220 <jorgen_ostling@users.sourceforge.net> for reporting this
223 3. Fixed dump's estimate when dealing with sparse inodes.
225 4. Modified dump to allow setting a blocksize bigger than 32kB
226 (raised the limit to 1024kB), because newer hardware needs
227 this for proper operation. Thanks to Dirk Traenapp
228 <dtraenapp@users.sourceforge.net> for reporting this.
230 5. Fixed a bug causing Dump to stop and report an error if an
231 inode number in the exclude file was followed by some amount
232 of whitespace. Thanks to Jeffrey Sofferin
233 <sofferin@users.sourceforge.net> for reporting this bug.
235 6. Fixed a bug which caused restore, in some particular cases,
236 to ask some 'scary' questions and leave a bunch of RSTTMP
237 directories behind when restoring incremental tapes. Thanks
238 to Philippe Troin <phil@fifi.org> for reporting this bug and
239 providing the test cases.
241 7. Changed the wording when inodes are excluded from dump:
242 replaced 'Added inode 7 to exclude list' with
243 'Excluding inode 7 (resize inode) from dump', as suggested
244 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
246 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
247 ===================================================================
249 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
250 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
251 <eros@lamel.bo.cnr.it> for reporting the bug.
253 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
254 ===================================================================
256 1. Made dump print out the ext2 logical block number in case of a read
257 error, which can be given as an argument to debugfs' ncheck command,
258 in order to find out the affected inode. Added note about this
259 usage in dump's man page.
261 2. Fixed a problem in restore when reading tapes written on big
262 endian machines with very old versions of dump. The patch was
263 contributed by George Helffrich <george@geology.bristol.ac.uk>.
265 3. Fixed the tape length calculation when using large tapes
266 and compression. Thanks to Georg Lippold
267 <g_lippold@sourceforge.net> for reporting the bug.
269 4. Added a new set of examples in dump_on_cd_2 directory, based
270 on dump_on_cd examples but somewhat enhanced, supporting DVD
271 media, and localized in english and german. Thanks to
272 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
274 5. Made dump save 32 bit UID/GID. Internally, this was achieved
275 by switching from the old BSD inode format to the new BSD
276 inode format, which means that the tape format was changed.
277 However, since all restore versions out there should
278 transparently support both inode formats, the change should
279 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
282 6. Fixed a lot of warnings in the code shown when compiling
283 with 'gcc -W'. Thanks to Matthias Andree
284 <matthias.andree@stud.uni-dortmund.de> for reporting this.
286 7. Fixed a small markup bug in the dump man page. Thanks to
287 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
290 8. Rewrote entirely the man pages using the tmac.an macro
291 package (Linux man page format) instead of the original BSD
292 format. They should be now cleaner and easier to modify.
294 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
295 ==================================================================
297 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
298 non Linux clients were misinterpreted. The description of the problem
299 (incompatible numbering in Linux mtio opcodes) is documented at
300 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
301 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
302 providing an excellent, cross-platform replacement for rmt in his
305 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
306 which caused restore to fail when the inode maps were not entirely
307 contained on the first volume (when using really small volumes or
308 when dumping a huge number of inodes).
310 3. Fixed a problem in dump, where files in subdirectories of directories
311 that have the nodump flag set (or being excluded with -e/-E) were
312 sometimes incorrectly dumped (instead of being excluded). The original
313 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
314 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
315 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
316 help testing the patch.
318 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
319 which makes one able to pipe the output of dump, by the net, to
320 a remote CD-burner server.
322 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
323 and use GNU's symbolic syntax over rmt instead of numerical values
324 to assure multiple platform compatibility.
326 6. Documented the -d option in restore.
328 7. Added a -v (verbose) mode to dump. For now it just prints the number
329 of the inode being dumped, but this could evolve in future versions
330 to include interesting debugging output.
332 8. Added a -o flag to restore, which automatically restores the current
333 directory permissions in -i or -x mode, without asking the operator
334 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
335 and Peter Samuel <peters@e-smith.com>.
337 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
338 ====================================================================
340 1. Fixed a bug in the QFA feature which could have caused
341 a bad tape positionning on restore (causing extra delays in
342 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
344 2. Added a small note in the dump man page specifying that
345 there should be no white space between the option letter and
346 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
348 3. Made restore work with older versions of the readline library,
349 by checking in configure for several extended symbols. Restore
350 can now be compiled with a readline as old as the 2.0 release
351 (though it may be a good idea to upgrade it to a more recent
352 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
353 reporting the build failures.
355 4. Fixed a performance problem with the QFA file creation in
356 dump, which made unnecessary seeks on the tape slowing down
357 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
358 reporting this issue.
360 5. Removed the inclusion of some kernel headers in the dump
361 source, which prevented the compile in some kernel/glibc
362 headers/architecture combination. Thanks to Bdale Garbee
363 <bdale@gag.com> for reporting the bug.
365 6. Added the appropriate error message when dump fails to
366 open the output file for writing. Thanks to Amith Varghese
367 <amithv@yahoo.com> for reporting this bug.
369 7. Made restore able to understand large Solaris ufsdump tapes
370 (containing inodes bigger than 4194304). Sun have introduced
371 an "extension" to the dump tape format when dealing with
372 those inodes, which was uncorrectly handled by Linux restore.
373 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
374 providing a test case.
376 8. Added the -m parameter to dump which optimises the output for
377 inodes having been changed but not modified since the last dump
378 ('changed' and 'modified' have the meaning defined in stat(2)).
379 For those inodes, dump will save only the metadata, instead of
380 saving the entire inode contents. Inodes which are either
381 directories or have been modified since the last dump are saved
382 in a regular way. Uses of this flag must be consistent, meaning
383 that either every dump in an incremental dump set have the flag,
386 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
387 =======================================================================
389 1. Fixed behaviour of dump when exceeding resource limits
392 2. Added the -L flag to restore to allow the user to specify a
393 maximal allowed number of miscompares when using restore
394 with the -C option to check the backup.
396 3. Detailed the manual entry for the -N option of restore.
398 4. Added the -a flag to restore to make able doing unattended
399 restores in -i or -x mode (automatically walks through the
400 multiple dump volumes).
402 5. Extended the QFA mode to work with local files and/or
403 remote tapes and files. This way, restore can know in advance
404 the tape number and the offset for the inodes to extract and
405 can minimize the extraction time by seeking directly to the
408 6. Added the -A <archive> option to both dump and restore,
409 which makes dump to archive a dump table-of-contents in
410 the specified file to be used by restore to determine
411 whether a file is in the dump file that is being restored.
412 (the archive file syntax is also compatible with the
413 Solaris ufsdump generated one).
415 7. Small fix in restore making it able to read some (broken ?)
416 Solaris ufsdump tapes.
418 8. Fixed dump to correctly recognise the root filesystem when using
419 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
420 for reporting this bug.
422 9. Added the -P <file> option to restore to create a
423 Quick File Access file from an already made dump. Patch
424 contributed by Uwe Gohlke <uwe@ugsoft.de>.
426 10. Made restore compile and run on Solaris, making it a
427 possible replacement for the standard ufsrestore. Port was
428 contributed by Uwe Gohlke <uwe@ugsoft.de>.
430 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
431 =====================================================================
433 1. Added a set of backup scripts from Eugenio Diaz
434 <getnito@yahoo.com> in the examples section. It features
435 automatic (cron based) full and incremental dumping of
436 several filesystems on a separate filesystem.
438 2. Fixed a off-by-one miscalculation which disabled dumping
439 a one letter subdirectory. Thanks to Chris Siebenmann
440 <cks@utcc.utoronto.ca> for reporting the bug.
442 3. Fixed several restore bugs occuring when trying to
443 restore some missing files on the tape. Thanks to Chris
444 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
446 4. Fixed --with-ldopts configure argument passing, installing from
447 a separate object directory, makefile cleanups contributed
448 by <splite@purdue.edu>.
450 5. Fix a bug which could caused, in some conditions, the highest
451 number inode of a filesystem, to not be dumped. Many thanks
452 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
455 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
456 =======================================================================
458 1. Added a mini howto from Patrick Walsh in the examples
461 2. Minor man pages syntax corrections. Thanks to
462 Chris Danis <screechco@home.com> for reporting the bugs.
464 3. Added a script from David B. Peterson <dave@toppledwagon.com>
465 to the examples section. It features dumping several
466 filesystems to a remote tape drive upon ssh.
468 4. Added a patch provided by Richard Jones <rich@annexia.org>
469 which allows BRADEMAX (number of read errors tolerated by
470 dump) to be adjusted using the -I option.
472 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
473 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
476 6. Add the -l option to restore to specify if, when doing a
477 remote restore, the file used to access the backup is a
478 regular file (the defaults being a tape drive). Restore needs
479 to know this information when reading a remote compressed
480 dump. Previously, this information was autodetected, but
481 the autodetection code fails (with ioctl: Inappropriate ioctl
482 for device) when using a non Linux remote box. Thanks to
483 many users and especially to Eros Albertazzi
484 <eros@lamel.bo.cnr.it> for reporting this.
486 7. Found a workaroung for the dump deadlock problem (3 childs
487 stuck in pause(), father in read()). The workaround seems
488 to work for me and several beta-testers. If it doesn't work
489 for you, please report back.
491 8. Updated the RPM spec file (BuildPrereq, URL etc).
493 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
494 ========================================================================
496 1. Fixed the permissions of a newly created QFA file by dump.
498 2. Cleaned up the source of dump (the external variables
499 definition was a complete mess, making possible to have
502 3. Fixed restore to use the full tape volume path when doing
503 a compare (since it changes the working directory to the
504 filesystem being compared in the process).
506 4. Added the -q option to dump which makes dump abort
507 whenever it needs operator attention. It should be
508 easier to use dump in scripts with this option.
510 5. Detect the use of incompatible options to dump and
511 refuse them (like -a and -B options together).
513 6. Added bzip2 compression to dump/restore (use option -j level
514 to select it). Note that you will need a restore version
515 >= 0.4b24 in order to restore a bzip2 compressed dump.
516 The same warning as for the zlib compression applies:
517 the tape format of a bzip2 dump is not compatible with the
518 original BSD tape format.
520 7. Fixed a overflow problem in dump corrupting the dump when
521 very large files were encountered. Thanks to Vladimir Nadvornik
524 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
525 kernel buffer/page cache before starting the dump, helping
526 a bit those who use dump on mounted filesystems. Thanks to
527 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
530 9. Updated the RPM spec file following the RedHat changes
531 (dynamically linked binaries now in /usr/sbin etc).
533 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
534 which enables restore to recognise multi volume compressed dumps
535 done on CD. Included his scripts for dump (which pipe the dump
536 output directly into cdrecord) and restore. There is now
537 possible to to backups to CD on the fly!
539 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
540 ===================================================================
542 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
543 Marcus Meissner (Caldera International Security Dept.).
545 2. Implement the Sun rmt extended protocol. Patch submitted
546 by Ian Gordon <iangordon@users.sourceforge.net>.
548 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
549 the linux kernel header. This ensures that dump always has the
550 latest version of this file. Patch submitted by
551 Andreas Dilger <adilger@turbolinux.com>.
553 4. Report any filesystem present in either /etc/fstab with a
554 positive passno or /etc/dumpdates in dump -w output.
555 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
557 5. Fixed the looping problem in dump introduced in the
560 6. Changed the -B option of dump to limit the size of
561 _compressed_ output per volume if compression is on.
562 Patch contributed by Helmut Jarausch
563 <jarausch@igpm.rwth-aachen.de>. Note however that, since
564 it is impossible to predict the size of the compressed
565 data before doing the compression, the -B limit is a bit
568 7. Fixed a bug in reading the operator typed file/tape path for
569 the next volume in restore.
571 8. Implemented a "-F script" option to restore which permits the
572 user to specify a script which will be launched at the
573 beginning of each tape, useful for automatic programming of
574 tape changers for example. See the restore man page for the
575 script parameters and return codes.
577 9. Small fix for the QFA routines provided by Uwe Gohlke
578 <uwe@ugsoft.de>, and some recommendations for QFA uses in
581 10. Fixed the multivolume restoring where making a mistake
582 to the 'Mount next tape' prompt caused several blocks to
585 11. Enhanced the -e option of dump to take as a parameter a
586 comma separated list of inode numbers.
588 12. Added the -E option to dump which specify a file containing
589 inode numbers to exclude from the dump.
591 13. Fixed the compressed multi-volume dump + restore.
593 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
594 ==================================================================
596 1. Made dump report the number of blocks dumped per volume.
597 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
599 2. Fix a bug in dump where waiting too much at the 'change volumes'
600 question caused the volume to be rewritten. Thanks to
601 Graham Reed <greed@users.sourceforge.net> for reporting the
602 bug and providing a patch.
604 3. Added a compression option to dump, contributed by Jerry
605 Peters <gapeters@worldnet.att.net>.
607 WARNING: the compression works only on files/pipes and
608 drives supporting variable block size.
610 WARNING2: tapes created using the compression feature are
611 incompatible with the standard dump tape format, and a
612 version of restore >= 0.4b22 will be needed for extraction.
614 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
615 architectures. Thanks to Paul Slootman <paul@debian.org> for
616 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
619 5. Many cleanups (CPP defines, const char warnings, check of
620 ext2fs COMPAT flags, time_t cleanups, added libext2 version
621 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
623 6. Made --prefix option work in configure. All the install path
624 are now based on the configure parameters.
626 7. Added the Quick File Access mode in dump/restore, contributed
627 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
628 a file tape position for each inode, and this file is used by
629 restore (if called with parameter Q and the filename)
630 to directly position the tape at the file restore is currently
631 working on. This saves hours when restoring single files from
632 large backups, saves the tapes and the drive's head. Use
633 --enable-qfa option of configure to compile in the QFA support.
635 8. Added the possibility to dump several files and directories
636 in a single invocation of dump. Thanks to Uwe Gohlke
637 <uwe@ugsoft.de> for implementing this option.
639 9. Fixed the dumping and restoring of files with holes
640 (files ending with holes didn't get dumped or restored
643 10. Fixed a socket descriptor leak in dump, which leaved opened
644 3 file descriptors per dump process (and there is one dump
647 11. Fixed dump large file system support, by explicit use of
648 open64/lseek64/etc functions (explicit use needed because
649 e2fsprogs libraries don't behave well when compiled with
650 FILE_OFFSET_BITS=64).
652 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
653 ======================================================================
655 1. Fixed some bugs in the dump -w|-W logic introduced by
656 the previous version. Thanks to Andreas Dilger
657 <adilger@turbolinux.com> for his help on this one.
659 2. Fixed again a compilation problem when using old e2fs
660 headers (filesystem label related). Thanks to many users
661 who reported this stupid error.
663 3. Fixed a build problem on old lib5 based systems dealing with
664 _PATH_MNTTAB being undefined. Thanks to John Adams
665 <johna@onevista.com> for reporting the bug.
667 4. Improved the error detection in restore when creating
668 the temporary files in TMPDIR. Now restore will corectly
669 report a 'no space left on device' error instead of
670 strange errors which could imply an archive corruption.
671 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
672 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
674 5. Added the throughput information in dump's progression
675 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
678 6. Use libext2fs's inode scanning routines, which are particularly
679 robust when dealing with errors (especially when having some
680 bad blocks on the filesystem). Many thanks to Colin
681 <colin@horizon.com> for reporting the bug, investigating
682 the issues, finding a workaround, writing the patch and
683 fully testing it... (of course, if this patch will break
684 anything, he is to blame for :-)).
686 7. Made dump and restore LFS aware. Dump can dump a filesystem
687 containing large files, generate a large file on output and
688 restore can restore them. This feature is not enabled by
689 default, use --enable-largefile option of configure to enable
690 it (you need to have a LFS aware glibc though). Thanks to
691 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
692 and to Theodore T'so <tytso@valinux.com> for his always
695 8. Made dump ask upon a tape write error if it should rewrite
696 the current volume (assume this is a bad tape) or if it should
697 assume an end-of-tape condition (useful for tape drives which
698 behaves badly at the end of the tape). Thanks to Andreas
699 Dilger <adilger@turbolinux.com> for the suggestion.
701 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
702 =======================================================================
704 1. Fixed a small compilation problem due to a change
705 in the definintion of the struct sigaction in
706 glibc 2.0 / libc5. Thanks to Gunther Schlegel
707 <schlegel@riege.de> for reporting the bug and to
708 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
711 2. Modified the label and uuid analysis in order to be
712 self-contained (independant of kernel/libc headers). This
713 should fix the compile with older kernel/libc headers and
714 will preserve the functionality. Thanks to Bernhard Erdmann
715 <bernhard.erdmann@gmx.de> for reporting the bug.
717 3. The 'exclude inode' option, if applied to a directory
718 inode, excludes now correctly all the leaves of this
719 directory. Thanks to John R. Dennison
720 <gerdesas@users.sourceforge.net> for reporting the bug.
722 4. Fixed the '-e' option to disable the possibility
723 to exclude the root inode (which causes the dumps to
724 be unreadable by restore). Prevented array overflow
725 when multiple -e options are used.
727 5. Fixed dump to correctly interpret a filesystem argument
728 which is a mountpoint and it is not an absolute path
729 (as specified in the fstab). Thanks to Bernhard R. Erdmann
730 <be@berdmann.de> for reporting the bug.
732 6. Made dump able to backup files larger than 2 GB. Note that
733 dump still doesn't cope with files larger than 4 GB.
735 7. Restore the real uid and gid before invoking an external
736 RSH program (big hole when dump or restore is suid root!).
738 8. Get the values for the default tape device and the location
739 of fstab file from the system headers. Thanks to
740 Andreas Dilger <adilger@turbolinux.com> for the patch.
742 9. Made dump -w|-W report all recognized filesystems
743 present in either /etc/fstab or /etc/dumpdates, and present
744 the list in the same order as in fstab file. Thanks
745 to Andreas Dilger <adilger@turbolinux.com> for the patch.
747 10. Made dump's -a (automatic end of tape detection) the
748 default. Specifying one of -B, -c, -d or -s options will
749 override the EOM detection. Thanks to Andreas Dilger
750 <adilger@turbolinux.com> for the patch.
752 11. Save the ext2 filesystem label into the dump volume label.
753 Specifying a volume label on the command line (-L option)
754 will override this feature. Thanks to Andreas Dilger
755 <adilger@turbolinux.com> for the patch.
757 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
758 =====================================================================
760 1. Fixed the signal handling in dump (which I broke in 0.4b17)
761 which was causing several strange dump failures (dump
762 hanged or segmentation faults etc).
764 2. Specified the default blocksize in the dump man page.
766 3. Changed two info messages of restore to be written on stdout
767 instead of stderr in order to leave stderr only for errors
768 or warnings. Thanks to Stephen Atwell
769 <satwell@urbana.css.mot.com> for the suggestion.
771 4. Corrected an off by one calculation which prevented
772 dumping a directory having a 1 character name length.
773 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
774 for reporting the bug.
776 5. Reinforce dump in order to allow only level 0 and no
777 -u option when dumping a subdirectory, and document
778 this in the man page. Thanks to Bernhard Erdmann
779 <bernhard.erdmann@gmx.de> for reporting the bug.
781 6. Fixed a small harmless bug in restore which caused
782 in some conditions hard links to be restored several
783 times (therefore generation some warning messages).
784 Thanks to Kenneth Porter <shiva@well.com> for
787 7. Updated the RPM spec file to the latest RedHat version,
788 providing FHS packaging and other cosmetic changes.
789 You will need RPM version >= 3.0.5 in order to build the RPM.
791 8. Updated the configure script to check for libtermcap
792 before checking for libreadline, because we need this
793 library in order to compile the readline support.
795 9. Made dump understand the LABEL= and UUID= notation
796 both in /etc/fstab and on the command line. Note that
797 you will need the /proc filesystem in order to use
798 these notations. Thanks to Erik Troan <ewt@redhat.com>
799 for providing the patch.
801 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
802 ===================================================================
804 1. Fixed a potential buffer overflow in restore. Thanks
805 to Stan Bubrouski <satan@fastdial.net> for reporting
808 2. Fixed a readline-related bug which prevented
809 'cat DUMPFILE | restore -i -f -' from working. Thanks
810 to Charles Karney <karney@users.sourceforge.net>
813 3. Changed a few "panic" into "exit", causing restore to
814 be more stable against some attacks (like the last one
815 reported on Bugtraq, although the last version of restore
816 was not vulnerable - just dumped core). Thanks to
817 Andreas Hasenack <andreas@conectiva.com.br> for reporting
820 4. Removed the suid-root bit on dump and restore in the
821 default build (and generated RPMs). It should be safer
822 now. Users who need the suid-root capabilities in order
823 to make network backups should read first the man page
824 of dump and enable the suid bit manually.
826 5. Added -ltermcap to the compile parameters for restore
827 when using readline support, in order to make the compile
828 process work on some systems (SuSE ?). Thanks to
829 Patrik Schindler <poc@pocnet.net> for reporting the bug.
831 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
832 ====================================================================
834 1. The -F script is called now *only* at the end of a tape,
835 not at the end of the dump. Thanks to Christian Haul
836 <haul@informatik.tu-darmstadt.de> for the bug report.
838 Normally, the device name and the current volume number
839 are passed on the command line of the script. However,
840 if you want the old style script (with no arguments
841 passed on the command line), you can enable it in
842 configure with the --enable-oldstylefscript.
844 2. Use posix signal handling to preserve dump functionality
845 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
848 3. Made the exit code of restore in case of a 'C'ompare
849 command reflect the result of the compare. An exit status
850 of 0 means the dump archive is correct, 1 means tape errors,
851 2 means that some files were modified. Thanks to Kenneth Porter
852 <shiva@well.com> for the suggestion.
854 4. Made (finally) quotes work in interactive restore.
856 5. Small fixes in order to allow dump to compile with a
857 really old e2fsprogs version. Thanks to Ian Zimmerman
858 <itz@speakeasy.org> for the bug report.
860 6. Add GNU readline capabilities to interactive restore.
861 Use configure's --enable-readline flag to enable this feature.
862 Thanks to Patrik Schindler <poc@pocnet.net> for the
865 7. Do the compare on the fly in restore 'C' mode (this will
866 allow not to exhaust the available /tmp space when
867 ccmparing large files). Thanks to Kenneth Porter
868 <shiva@well.com> for the suggestion.
870 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
871 ====================================================================
873 1. Fixed some several duplicate 'DUMP: DUMP:' in the
876 2. Corrected the estimation of blocks to dump. Note that
877 this is still wrong for large directory inodes, due
878 to the size of a BSD directory entry on the tape
879 (estimation is based on the size of the ext2 directory,
880 which is smaller because it doesn't contain the null
881 character at the end).
883 3. Made dump report the total number of MB written to
884 tape at the end of run. Thanks to W. Reilly Cooley
885 <wcooley@nakedape.cc> for the patch.
887 4. Added the -X option to restore giving the possibility
888 to read the names of the files to be extracted/listed
889 from a text file (in addition of the command line).
890 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
893 5. Added the device name and the current volume number
894 as arguments to the end of tape script (dump -F option).
896 6. Made the multi-volume dump work again (after having
897 broken it in 0.4b15).
899 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
900 ===================================================================
902 1. Added a prompt command in interactive restore mode. Thanks
903 to Andreas Dilger <adilger@home.com> for the patch.
905 2. Fixed a buffer overflow problem in dump (caused by
906 not checking the size of the filesystem parameter).
907 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
908 reporting this on Bugtraq (and to several dump users
909 who forwarded me his mail).
911 3. Added the '-F script' option to dump in order to
912 launch a script at the end of each tape (to be used
913 with a tape changer, or to notify the sysadmin by
916 4. Fixed a bug in restore compare code caused by the changes
919 5. Fixed the treatment of options using the old BSD syntax
920 in both dump and restore.
922 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
923 =======================================================================
925 1. Fixed a bug in dump which may have caused invalid deleted
926 directories to be dumped out if they were deleted after the
927 mapping pass. This could occure on active filesystem and lead
928 to heap corruption (causing dump malfunction in many possible ways).
929 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
930 bug and submitting the patch.
932 2. Fixed the handling of the filesystem parameter in dump. A
933 '/mnt/disk' parameter caused the disk contents to be dumped,
934 but a '/mnt/disk/' parameter caused the mountpoint directory
935 to be dumped (generally an empty directory).
937 3. Improved the output of dump in order to tell which directory
938 it is currently dumping (when dumping a subtree).
940 4. Added the '-e' exclude inode option to dump. Thanks to
941 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
943 5. Added a REPORTING-BUGS file in order to provide a guide
944 on how to correctly report a bug in dump/restore.
946 6. Fixed a restore problem when restoring a hard link to an inode
947 having the immutable or append-only attribute set. Thanks to
948 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
950 7. Fixed a compatibility problem between dumps made on little
951 endian machines (the format was correct) and big endian
952 machines (the format was incorrect). This fix break the
953 compatibility with the older dumps made on big endian
954 machines (sparc, m86k, ppc etc). For the first time in
955 linux dump's history (I believe), the dumps made by *BSD,
956 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
957 so interchangeable. Thanks to Rob Cermak
958 <cermak@ahab.rutgers.edu> for submitting the bug and
959 helping me test the fix.
961 8. Fixed the way dump reports the remaining percent/time, if
962 the number of blocks actually dumped exceeds the estimated
963 number of blocks. Thanks to Jean-Paul van der Jagt
964 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
966 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
967 ======================================================================
969 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
970 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
972 2. Removed the requirement to build the RPM as root from the
973 spec file. Thanks to Christian Weisgerber
974 <naddy@mips.rhein-neckar.de> for submitting this.
976 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
977 causing dump to block when dumping really huge filesystems.
978 Many thanks to Patrik Schindler <poc@pocnet.net> for
979 helping me find this bug.
981 4. Fixed the treatment for an interrupt signal when dump access
982 the remote tape through RSH. Thanks to Christian Weisgerber
983 <naddy@mips.rhein-neckar.de> for providing the patch.
985 5. Fixed a bug which was causing dump/restore to display
986 garbage characters instead of the remote host name.
988 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
989 =====================================================================
991 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
992 <kukuk@suse.de> for submitting the patch.
994 2. Fix for the exit code when using the size estimate option of
995 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
996 submitting the patch.
998 3. Handle EINTR in atomical reads/writes in dump, which was causing
999 dump to fail on some systems. Thanks to Eric Jergensen
1000 <eric@dvns.com> for reporting the bug and submitting the patch.
1002 4. Handle more than 16 characters for the device names in dumpdates.
1003 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1004 tracking down the problem and proposing the solution.
1006 5. Fixed a bug in dump which prevented the creation of the
1007 dumpdates file when doing a 0-level dump without already
1008 having a dumpdates file. Thanks to Patrik Schindler
1009 <poc@pocnet.net> for reporting the bug.
1011 6. Changed the way dump 'S' flag reports the size estimate
1012 from number of blocks into bytes (making it compatible
1013 with the Solaris version, and simplifying things for
1014 amanda users). Thanks to Jason L Tibbitts III
1015 <tibbs@math.uh.edu> for reporting the bug.
1017 7. Fixed a compatibility problem in linux/alpha dump tape format.
1018 Now the linux/alpha dump are (again) compatible with the
1019 other dump formats. But this breaks compatibility with
1020 older dumps made on alpha. Thanks to Mike Tibor
1021 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1023 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1024 ======================================================================
1026 1. Added a '--enable-kerberos' to configure.
1028 2. Added a 'S' option to dump which determines the amount of space
1029 that is needed to perform the dump without actually doing it, similar
1030 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1031 <cermak@ahab.rutgers.edu>.
1033 3. Added a 'M' multi-volume option to dump and restore which enables
1034 dumping to multiple files (useful when dumping to an ext2
1035 partition to make several dump files in order to bypass the 2GB
1036 file size limitation). The 'f' argument is treated as a prefix and
1037 the output files will be named <prefix>001, <prefix>002 etc. With
1038 the 'M' flag, restore automatically selects the right file without
1039 asking to enter a new tape each time.
1041 4. Fixed a memory leak which was causing dump to grow very big
1042 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1043 Fearon <jasonf@netrider.org.au> for reporting the bug.
1045 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1046 ======================================================================
1048 1. Make configure test if the system glob routines support
1049 extended syntax (ALTDIRFUNC). If not, use the internal glob
1050 routines instead of system ones. Thanks to Bernhard Sadlowski
1051 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1052 and helping me resolve this and other minor libc5 compiling
1055 2. Fix a problem when dumping a ext2fs with the 'filetype'
1056 feature enabled. Thanks to Patrick J. LoPresti
1057 <patl@cag.lcs.mit.edu> for reporting the bug and to
1058 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1060 3. Made the nodump flag work on directories. A directory which
1061 has the nodump flag gets never dumped, regardless of its
1064 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1065 which allows dump on an active ext3 filesystem. However, this
1066 is a "quick and dirty" patch which enables backup of an ext3
1067 filesystem through the ext2 compatibility (by ignoring the
1068 NEEDS_RECOVERY bit). The journal file is not recognized and
1069 it is dumped (it should not).
1071 5. Test the superblock compatibility flags when dumping, in order
1072 to be sure that we know how to deal with specific features.
1074 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1075 ====================================================================
1077 1. Use lchown instead of chown, fixing a possible security problem
1078 when restoring symlinks (a malicious user could use this
1079 to deliberately corrupt the ownership of important system files).
1080 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1081 this and providing the patch.
1083 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1084 ====================================================================
1086 1. Put dump sources under CVS, added Id tags in all files so
1087 one can use 'ident' on binary files.
1089 2. Added the dump/restore version in the usage text so one can
1090 easily verify the version he is using.
1092 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1093 a va_start/va_end problem on linux-ppc (always call va_start
1094 va_end in pairs each time we use a vararg function).
1096 4. Added again the DT_* constants because old libc does not
1097 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1098 for submitting the bug report.
1100 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1101 this should enable dumping big (huge) filesystems.
1103 6. Added the RSH environment variable in order to be able to
1104 use a rsh replacement like ssh when doing remote backups (and
1105 bypass the security limitations of rcmd). Now you can do remote
1106 backups without being root (or making dump setuid root).
1108 7. Modified again the way dumpdates works. For incremental dumps,
1109 we need to read dumpdates even if we are not using 'u' option.
1110 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1113 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1114 ===================================================================
1116 1. Removed the 'k' flag from the restore 'about' text if kerberos
1117 was not compiled in.
1119 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1120 to them (fsetflags takes a char*, setflags an open fd!).
1122 3. (f)setflags is called only if the flags aren't empty. If the
1123 file is a special file, a warning is printed, because changing
1124 flags implies opening the device. Normally, a special file
1125 should not have any flag... (Debian bug #29775, patch provided
1126 by Abhijit Dasgupta <abhijit@ans.net>).
1128 4. Made possible to dump a file system not mentioned in /etc/fstab.
1129 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1131 5. Changed the default behaviour to not create dumpdates
1132 unless 'u' option is specified. Removed the old "debian-patch"
1133 which provided the same thing. (Debian bug #38136, #33818).
1135 6. Removed all those dump*announce, since they were getting old...
1137 7. Added warning messages if dumpdates does not exist and
1138 when an inferior level dump does not exist (except for a level 0
1141 8. Debugged the glob calls in interactive mode: restore used a
1142 dirent struct which was different from the /usr/include/dirent.h
1143 one (this used to work, is it a glibc2 change?), so none of the
1144 compat glob (which used /usr/include/dirent.h) or the system glob
1145 worked. Restore use now the system dirent (and the system
1146 DT_* constants), which are compatible with BSD ones.
1148 9. Added a configure flag (--with-dumpdatespath) to specify
1149 the location of dumpdates file. By default, it is
1152 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1153 included the current date/version in man pages.
1155 11. Corrected the estimation of remaining time when
1156 the operator doesn't change the tapes quickly enough. This
1157 was an old bug, I thought I corrected it, and discovered
1158 that in fact it was corrected in two different places, so
1159 the results canceled each other...
1161 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1162 ===================================================================
1164 1. Integrated multiple patches from RedHat, Debian and SuSE:
1166 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1168 - several fixes in the man pages.
1169 - update the default tape device to /dev/st0.
1170 - many updates for Linux Alpha (byte ordering, size_t etc).
1172 - use environment variable for TMPDIR (instead of /tmp).
1173 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1174 - workaround egcs bug (RedHat bugs #4281 and #2989).
1175 - wire $(OPT) throughout Makefile's.
1177 2. Upgrade the dump revision to 1, making possible to dump filesystems
1178 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1180 3. Fix some compile warnings, prototype all functions.
1182 4. Use glibc err/glob instead of internal compatibility
1183 routines (only if available).
1185 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1186 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1188 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1189 ======================================================================
1191 1. Integrated the changes from FreeBSD-3.1-RELEASE
1192 (mostly bug fixes, buffer overruns, dump has now an "automatic
1193 tape length calculation" flag, dump/restore can use kerberos now
1194 (this is NOT tested), use environment variables for TAPE and
1197 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1199 3. Corrected a bug in restore when using 'C' option with multi-volumes
1200 tapes (files splited accros two tapes give "size changed" errors
1203 4. Corrected the long standing bug when dumping multiple tapes.
1204 This works for me, needs further testing.
1206 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1207 ====================================================================
1209 1. Dump now runs correctly on kernels 2.1.x
1210 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1212 Changes between versions 0.4b2 and 0.4b3
1213 ========================================
1215 1. Use realpath() if available
1217 2. Report statistics
1219 Changes between versions 0.4b1 and 0.4b2
1220 ========================================
1222 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1225 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1227 3. Fixed configure.in to correctly handle --enable-rmt
1229 Changes between versions 0.3 and 0.4b1
1230 ======================================
1232 1. Integrated the changes from 4.4BSD-Lite2
1234 2. Integrated the patches from Debian and Red Hat
1236 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1238 4. Changed dump to use the Ext2fs library to get block addresses. This
1239 should solve the endianness problem on SparcLinux.
1241 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1242 distribution's one) to use autoconf
1244 6. Fixed a few minor bugs
1246 Changes between versions 0.2e and 0.2f
1247 ======================================
1249 1. Added the creation of named pipes (fifos) in restore.
1251 2. Added the -N flag in the restore manual page.
1253 3. Added the file kernel.patch which contains the llseek() optimization
1254 patch for 1.2.x kernels.
1256 4. Fixed a bug in the restoration of symbolic links: owner and group were
1259 5. Integrated some changes from FreeBSD 2.2.
1261 6. Added a call to ftruncate() after restoring each file to restore
1262 correctly files ending by a hole.
1264 Changes between versions 0.2d and 0.2e
1265 ======================================
1267 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1268 with owner = root (0) and group = root/wheel/whatever (0).
1270 Changes between versions 0.2c and 0.2d
1271 ======================================
1273 1. Dump is now able to backup 2GB+ filesystems.
1275 2. Dump and restore can now be linked as static binaries.
1277 Changes between versions 0.2b and 0.2c
1278 ======================================
1280 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1282 Changes between versions 0.2a and 0.2b
1283 ======================================
1285 1. Really fixed the bug that I should have corrected in 0.2a.
1287 2. Enabled optimization again.
1289 Changes between versions 0.2 and 0.2a
1290 =====================================
1292 1. Disabled the optimization during compilation.
1294 Changes between versions 0.1 and 0.2
1295 ====================================
1297 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1298 the fs_type field (actually, I modified the file fstab.c to make it
1299 use the mntent functions).
1301 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1302 made by dump should be readable by the BSD restore and backups made
1303 by the BSD dump should be readable by restore. Unfortunately, this
1304 means that the dump format has changed between version 0.1 and version
1307 3. Dump is now able to backup a subtree, it is no longer limited to whole
1308 filesystems like the BSD version.
1310 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1313 Changes between versions 0.0 and 0.1
1314 ====================================
1316 1. Now create links rdump and rrestore during the `make install' step.
1318 2. Linux port specific bugs added to the manual pages
1320 3. Incorrect estimation of the number of tapes blocks fixed when doing
1321 incremental backups.
1323 4. Better ls-like format in restore in interactive mode.
