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 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
22 =======================================================================
24 1. Added a note in the dump man page saying that the default
25 blocksize can be 32 if -d is used with a high density argument.
26 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
29 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
30 LDFLAGS environment variables. Thanks to Arcady Genkin
31 <antipode@users.sourceforge.net> for reporting the bug.
33 3. Made -e/-E options of dump accept an unlimited number of inodes
34 to be excluded, rather than a hardcoded maximum. Thanks to
35 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
37 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
38 and -D_USE_BSD_SIGNAL defines in configure in order to solve
39 64bit build problems because quad_t is redifined with a
40 different signature. Thanks to Mike Harris <mharris@redhat.com>
41 for reporting this bug.
43 5. Made restore build on Solaris, making possible to
44 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
45 <uwe@ugsoft.de> for the patch.
47 6. Made an extension in the dump tape format capable of saving
48 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
49 wrote the extension and contributed the restore code back
50 into this codebase. The same extension mechanism will be
51 used in the future to save ACLs...
53 7. Made rmt work correctly with regard to QFA and local/remote
54 files and tapes. The remote access will however work only
55 when the dump provided rmt version is used. If you want to
56 use another rmt server, please do not use the QFA feature.
57 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
59 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
60 ====================================================================
62 1. Fixed the INSTALL file to reflect the actual install paths.
63 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
66 2. Fixed the configure script to only check for headers presence
67 instead of trying to compile them. This should fix issues
68 with old build environments. Thanks to Kari Lempiainen
69 <kari@funky.pp.fi> for reporting the bug.
71 3. Fixed restore to correctly ignore sockets when comparing
72 a dump (as socket cannot be properly restored anyway). Thanks
73 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
75 4. Fixed restore to correctly access the archive file (-A argument)
76 even when using a remote tape. Thanks to Fabrice Bellet
77 <fabrice@bellet.info> for reporting the bug.
79 5. Fixed (again) handling of long (largefile) seeks in rmt.
80 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
83 6. Fixed restore corner case when dealing with large block sizes
84 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
85 <fabrice@bellet.info> for reporting the bug.
87 7. Fixed a bug preventing dump to access a filesystem having
88 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
89 for reporting the bug.
91 8. Made dump store dump dates using explicit timezones, fixing a
92 problem with incremental dumps if the timezone is modified
93 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
94 the bug report and the patch.
96 9. Fixed a bug encountered when dumping individual files (not full
97 filesystems or directories) and dangling symbolic links happen
98 to be in the list of files. For as far as dump is concerned,
99 dangling symbolic links are allowed, and are dumped as is.
100 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
101 bug and providing the fix.
103 10. Fixed open and creation modes and permissions for QFA and
104 table-of-contents files in dump and restore. Thanks to
105 Philippe Troin <phil@fifi.org> for the patch.
107 11. Fixed the archive file descriptor handling enabling it to be 0.
108 This can happen in some cases when shell redirections are used.
109 Thanks to Philippe Troin <phil@fifi.org> for the patch.
111 12. Delayed the opening of archive file until after suid had been
112 dropped (fixing a possible security issue if dump is suid).
113 Thanks to Philippe Troin <phil@fifi.org> for the patch.
115 13. Fixed the 'S' command handling in the rmt client part.
116 Thanks to Philippe Troin <phil@fifi.org> for the patch.
118 14. Modified the end-of-tape script handling to print out statistics
119 (and stop the timer) before launching the eot script. Also, the eot
120 script does not get run anymore when using -M (which makes sense) or
121 when multiple tapes are listed on the command line
122 (-f tape0,tape1,tapen) (which also makes sense).
123 Thanks to Philippe Troin <phil@fifi.org> for the patch.
125 15. Relicensed dump/restore under the 'revised' BSD license, as per
126 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
128 16. Added LZO compression to dump. This new compression method has
129 the advantage of being super fast, thus not killing tape streaming
130 on slow machines. Thanks to Helmut Jarausch
131 <jarausch@igpm.rwth-aachen.de> for the patch and to
132 Markus Oberhumer <markus@oberhumer.com> for giving special permission
133 to include his miniLZO project (GPL licensed) in dump/restore.
135 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
136 <ant@notatla.demon.co.uk> for reporting the bugs.
138 18. Added a special rmt version which can do encryption when writing
139 to tape. Read examples/encrypted_rmt/README for details on
140 how to enable and configure it. Thanks to Ken Lalonde
141 <ken@globalremit.com> for the patch.
143 19. Made dump work with 2.5 kernel end of tape early warning semantics.
144 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
146 20. Fixed a bug which caused dump -w|-W not to work anymore, because
147 the fs_freq and fs_passno fields in /etc/mtab are always set
148 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
151 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
152 =======================================================================
154 1. Added a note in the restore man page clarifying the question
155 'set the permissions on the current directory ?' asked by
156 restore at the end of treatment in -i and -x modes.
158 2. Fixed the endianess issues when reading compressed tapes.
159 Thanks to Dark Force <daq4th@users.sourceforge.net> for
160 reporting this bug and providing test cases.
162 3. Fixed the "ACL won't be dumped" warning message (which showed
163 an extra, unrelated error message). Thanks to Dragan Krnic
164 <dkrnic@lycos.com> for reporting this bug.
166 4. Made dump look first into /etc/mtab, then into /etc/fstab
167 when searching for filesystem paths. Also fixed some problems
168 caused by binding mounts or multiple block device mounts.
169 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
170 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
171 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
172 and #160305, Sourceforge bugs #618699 and #679832).
174 5. Made dump's -I option accept the value '0' meaning all the
175 read errors will be ignored. This can be useful when running
176 dump from unattended sessions (like cron jobs). Thanks to
177 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
179 6. Fixed the output of dump to indicate 'blocks' instead of
180 'tape blocks' in the various messages (blocks are always
181 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
182 made it clearly print the current blocksize at the start of
183 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
186 7. Made rmt understand long (largefiles) seeks.
188 8. Fixed build with very old versions of libext2fs, where
189 EXT2_FT_* constants were undefined.
191 9. Made dump accept the dumpdates path on the command line
192 (-D file option) instead of using only the hardcoded one.
193 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
196 10. Enabled rmt, LFS, readline, QFA options by default in
197 ./configure. Updated the configure process (new versions
198 of config.guess, config.sub etc).
200 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
201 =======================================================================
203 1. Changed dump to use fcntl(F_SETLK) style locking instead
204 of flock() when locking the dumpdates file. With the old
205 locking scheme, a local user having read rights on the
206 dumpdates file could be able to do a Denial of Service attack
207 on dump. In order to lock the dumpdates file with the new
208 scheme, the user would need to have write access on the file.
209 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
210 reporting the bug (originally a bugtraq post).
212 2. Fixed interactive 'ls' which caused spurious errors warnings
213 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
214 <jorgen_ostling@users.sourceforge.net> for reporting this
217 3. Fixed dump's estimate when dealing with sparse inodes.
219 4. Modified dump to allow setting a blocksize bigger than 32kB
220 (raised the limit to 1024kB), because newer hardware needs
221 this for proper operation. Thanks to Dirk Traenapp
222 <dtraenapp@users.sourceforge.net> for reporting this.
224 5. Fixed a bug causing Dump to stop and report an error if an
225 inode number in the exclude file was followed by some amount
226 of whitespace. Thanks to Jeffrey Sofferin
227 <sofferin@users.sourceforge.net> for reporting this bug.
229 6. Fixed a bug which caused restore, in some particular cases,
230 to ask some 'scary' questions and leave a bunch of RSTTMP
231 directories behind when restoring incremental tapes. Thanks
232 to Philippe Troin <phil@fifi.org> for reporting this bug and
233 providing the test cases.
235 7. Changed the wording when inodes are excluded from dump:
236 replaced 'Added inode 7 to exclude list' with
237 'Excluding inode 7 (resize inode) from dump', as suggested
238 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
240 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
241 ===================================================================
243 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
244 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
245 <eros@lamel.bo.cnr.it> for reporting the bug.
247 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
248 ===================================================================
250 1. Made dump print out the ext2 logical block number in case of a read
251 error, which can be given as an argument to debugfs' ncheck command,
252 in order to find out the affected inode. Added note about this
253 usage in dump's man page.
255 2. Fixed a problem in restore when reading tapes written on big
256 endian machines with very old versions of dump. The patch was
257 contributed by George Helffrich <george@geology.bristol.ac.uk>.
259 3. Fixed the tape length calculation when using large tapes
260 and compression. Thanks to Georg Lippold
261 <g_lippold@sourceforge.net> for reporting the bug.
263 4. Added a new set of examples in dump_on_cd_2 directory, based
264 on dump_on_cd examples but somewhat enhanced, supporting DVD
265 media, and localized in english and german. Thanks to
266 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
268 5. Made dump save 32 bit UID/GID. Internally, this was achieved
269 by switching from the old BSD inode format to the new BSD
270 inode format, which means that the tape format was changed.
271 However, since all restore versions out there should
272 transparently support both inode formats, the change should
273 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
276 6. Fixed a lot of warnings in the code shown when compiling
277 with 'gcc -W'. Thanks to Matthias Andree
278 <matthias.andree@stud.uni-dortmund.de> for reporting this.
280 7. Fixed a small markup bug in the dump man page. Thanks to
281 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
284 8. Rewrote entirely the man pages using the tmac.an macro
285 package (Linux man page format) instead of the original BSD
286 format. They should be now cleaner and easier to modify.
288 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
289 ==================================================================
291 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
292 non Linux clients were misinterpreted. The description of the problem
293 (incompatible numbering in Linux mtio opcodes) is documented at
294 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
295 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
296 providing an excellent, cross-platform replacement for rmt in his
299 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
300 which caused restore to fail when the inode maps were not entirely
301 contained on the first volume (when using really small volumes or
302 when dumping a huge number of inodes).
304 3. Fixed a problem in dump, where files in subdirectories of directories
305 that have the nodump flag set (or being excluded with -e/-E) were
306 sometimes incorrectly dumped (instead of being excluded). The original
307 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
308 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
309 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
310 help testing the patch.
312 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
313 which makes one able to pipe the output of dump, by the net, to
314 a remote CD-burner server.
316 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
317 and use GNU's symbolic syntax over rmt instead of numerical values
318 to assure multiple platform compatibility.
320 6. Documented the -d option in restore.
322 7. Added a -v (verbose) mode to dump. For now it just prints the number
323 of the inode being dumped, but this could evolve in future versions
324 to include interesting debugging output.
326 8. Added a -o flag to restore, which automatically restores the current
327 directory permissions in -i or -x mode, without asking the operator
328 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
329 and Peter Samuel <peters@e-smith.com>.
331 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
332 ====================================================================
334 1. Fixed a bug in the QFA feature which could have caused
335 a bad tape positionning on restore (causing extra delays in
336 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
338 2. Added a small note in the dump man page specifying that
339 there should be no white space between the option letter and
340 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
342 3. Made restore work with older versions of the readline library,
343 by checking in configure for several extended symbols. Restore
344 can now be compiled with a readline as old as the 2.0 release
345 (though it may be a good idea to upgrade it to a more recent
346 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
347 reporting the build failures.
349 4. Fixed a performance problem with the QFA file creation in
350 dump, which made unnecessary seeks on the tape slowing down
351 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
352 reporting this issue.
354 5. Removed the inclusion of some kernel headers in the dump
355 source, which prevented the compile in some kernel/glibc
356 headers/architecture combination. Thanks to Bdale Garbee
357 <bdale@gag.com> for reporting the bug.
359 6. Added the appropriate error message when dump fails to
360 open the output file for writing. Thanks to Amith Varghese
361 <amithv@yahoo.com> for reporting this bug.
363 7. Made restore able to understand large Solaris ufsdump tapes
364 (containing inodes bigger than 4194304). Sun have introduced
365 an "extension" to the dump tape format when dealing with
366 those inodes, which was uncorrectly handled by Linux restore.
367 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
368 providing a test case.
370 8. Added the -m parameter to dump which optimises the output for
371 inodes having been changed but not modified since the last dump
372 ('changed' and 'modified' have the meaning defined in stat(2)).
373 For those inodes, dump will save only the metadata, instead of
374 saving the entire inode contents. Inodes which are either
375 directories or have been modified since the last dump are saved
376 in a regular way. Uses of this flag must be consistent, meaning
377 that either every dump in an incremental dump set have the flag,
380 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
381 =======================================================================
383 1. Fixed behaviour of dump when exceeding resource limits
386 2. Added the -L flag to restore to allow the user to specify a
387 maximal allowed number of miscompares when using restore
388 with the -C option to check the backup.
390 3. Detailed the manual entry for the -N option of restore.
392 4. Added the -a flag to restore to make able doing unattended
393 restores in -i or -x mode (automatically walks through the
394 multiple dump volumes).
396 5. Extended the QFA mode to work with local files and/or
397 remote tapes and files. This way, restore can know in advance
398 the tape number and the offset for the inodes to extract and
399 can minimize the extraction time by seeking directly to the
402 6. Added the -A <archive> option to both dump and restore,
403 which makes dump to archive a dump table-of-contents in
404 the specified file to be used by restore to determine
405 whether a file is in the dump file that is being restored.
406 (the archive file syntax is also compatible with the
407 Solaris ufsdump generated one).
409 7. Small fix in restore making it able to read some (broken ?)
410 Solaris ufsdump tapes.
412 8. Fixed dump to correctly recognise the root filesystem when using
413 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
414 for reporting this bug.
416 9. Added the -P <file> option to restore to create a
417 Quick File Access file from an already made dump. Patch
418 contributed by Uwe Gohlke <uwe@ugsoft.de>.
420 10. Made restore compile and run on Solaris, making it a
421 possible replacement for the standard ufsrestore. Port was
422 contributed by Uwe Gohlke <uwe@ugsoft.de>.
424 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
425 =====================================================================
427 1. Added a set of backup scripts from Eugenio Diaz
428 <getnito@yahoo.com> in the examples section. It features
429 automatic (cron based) full and incremental dumping of
430 several filesystems on a separate filesystem.
432 2. Fixed a off-by-one miscalculation which disabled dumping
433 a one letter subdirectory. Thanks to Chris Siebenmann
434 <cks@utcc.utoronto.ca> for reporting the bug.
436 3. Fixed several restore bugs occuring when trying to
437 restore some missing files on the tape. Thanks to Chris
438 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
440 4. Fixed --with-ldopts configure argument passing, installing from
441 a separate object directory, makefile cleanups contributed
442 by <splite@purdue.edu>.
444 5. Fix a bug which could caused, in some conditions, the highest
445 number inode of a filesystem, to not be dumped. Many thanks
446 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
449 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
450 =======================================================================
452 1. Added a mini howto from Patrick Walsh in the examples
455 2. Minor man pages syntax corrections. Thanks to
456 Chris Danis <screechco@home.com> for reporting the bugs.
458 3. Added a script from David B. Peterson <dave@toppledwagon.com>
459 to the examples section. It features dumping several
460 filesystems to a remote tape drive upon ssh.
462 4. Added a patch provided by Richard Jones <rich@annexia.org>
463 which allows BRADEMAX (number of read errors tolerated by
464 dump) to be adjusted using the -I option.
466 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
467 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
470 6. Add the -l option to restore to specify if, when doing a
471 remote restore, the file used to access the backup is a
472 regular file (the defaults being a tape drive). Restore needs
473 to know this information when reading a remote compressed
474 dump. Previously, this information was autodetected, but
475 the autodetection code fails (with ioctl: Inappropriate ioctl
476 for device) when using a non Linux remote box. Thanks to
477 many users and especially to Eros Albertazzi
478 <eros@lamel.bo.cnr.it> for reporting this.
480 7. Found a workaroung for the dump deadlock problem (3 childs
481 stuck in pause(), father in read()). The workaround seems
482 to work for me and several beta-testers. If it doesn't work
483 for you, please report back.
485 8. Updated the RPM spec file (BuildPrereq, URL etc).
487 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
488 ========================================================================
490 1. Fixed the permissions of a newly created QFA file by dump.
492 2. Cleaned up the source of dump (the external variables
493 definition was a complete mess, making possible to have
496 3. Fixed restore to use the full tape volume path when doing
497 a compare (since it changes the working directory to the
498 filesystem being compared in the process).
500 4. Added the -q option to dump which makes dump abort
501 whenever it needs operator attention. It should be
502 easier to use dump in scripts with this option.
504 5. Detect the use of incompatible options to dump and
505 refuse them (like -a and -B options together).
507 6. Added bzip2 compression to dump/restore (use option -j level
508 to select it). Note that you will need a restore version
509 >= 0.4b24 in order to restore a bzip2 compressed dump.
510 The same warning as for the zlib compression applies:
511 the tape format of a bzip2 dump is not compatible with the
512 original BSD tape format.
514 7. Fixed a overflow problem in dump corrupting the dump when
515 very large files were encountered. Thanks to Vladimir Nadvornik
518 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
519 kernel buffer/page cache before starting the dump, helping
520 a bit those who use dump on mounted filesystems. Thanks to
521 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
524 9. Updated the RPM spec file following the RedHat changes
525 (dynamically linked binaries now in /usr/sbin etc).
527 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
528 which enables restore to recognise multi volume compressed dumps
529 done on CD. Included his scripts for dump (which pipe the dump
530 output directly into cdrecord) and restore. There is now
531 possible to to backups to CD on the fly!
533 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
534 ===================================================================
536 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
537 Marcus Meissner (Caldera International Security Dept.).
539 2. Implement the Sun rmt extended protocol. Patch submitted
540 by Ian Gordon <iangordon@users.sourceforge.net>.
542 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
543 the linux kernel header. This ensures that dump always has the
544 latest version of this file. Patch submitted by
545 Andreas Dilger <adilger@turbolinux.com>.
547 4. Report any filesystem present in either /etc/fstab with a
548 positive passno or /etc/dumpdates in dump -w output.
549 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
551 5. Fixed the looping problem in dump introduced in the
554 6. Changed the -B option of dump to limit the size of
555 _compressed_ output per volume if compression is on.
556 Patch contributed by Helmut Jarausch
557 <jarausch@igpm.rwth-aachen.de>. Note however that, since
558 it is impossible to predict the size of the compressed
559 data before doing the compression, the -B limit is a bit
562 7. Fixed a bug in reading the operator typed file/tape path for
563 the next volume in restore.
565 8. Implemented a "-F script" option to restore which permits the
566 user to specify a script which will be launched at the
567 beginning of each tape, useful for automatic programming of
568 tape changers for example. See the restore man page for the
569 script parameters and return codes.
571 9. Small fix for the QFA routines provided by Uwe Gohlke
572 <uwe@ugsoft.de>, and some recommendations for QFA uses in
575 10. Fixed the multivolume restoring where making a mistake
576 to the 'Mount next tape' prompt caused several blocks to
579 11. Enhanced the -e option of dump to take as a parameter a
580 comma separated list of inode numbers.
582 12. Added the -E option to dump which specify a file containing
583 inode numbers to exclude from the dump.
585 13. Fixed the compressed multi-volume dump + restore.
587 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
588 ==================================================================
590 1. Made dump report the number of blocks dumped per volume.
591 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
593 2. Fix a bug in dump where waiting too much at the 'change volumes'
594 question caused the volume to be rewritten. Thanks to
595 Graham Reed <greed@users.sourceforge.net> for reporting the
596 bug and providing a patch.
598 3. Added a compression option to dump, contributed by Jerry
599 Peters <gapeters@worldnet.att.net>.
601 WARNING: the compression works only on files/pipes and
602 drives supporting variable block size.
604 WARNING2: tapes created using the compression feature are
605 incompatible with the standard dump tape format, and a
606 version of restore >= 0.4b22 will be needed for extraction.
608 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
609 architectures. Thanks to Paul Slootman <paul@debian.org> for
610 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
613 5. Many cleanups (CPP defines, const char warnings, check of
614 ext2fs COMPAT flags, time_t cleanups, added libext2 version
615 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
617 6. Made --prefix option work in configure. All the install path
618 are now based on the configure parameters.
620 7. Added the Quick File Access mode in dump/restore, contributed
621 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
622 a file tape position for each inode, and this file is used by
623 restore (if called with parameter Q and the filename)
624 to directly position the tape at the file restore is currently
625 working on. This saves hours when restoring single files from
626 large backups, saves the tapes and the drive's head. Use
627 --enable-qfa option of configure to compile in the QFA support.
629 8. Added the possibility to dump several files and directories
630 in a single invocation of dump. Thanks to Uwe Gohlke
631 <uwe@ugsoft.de> for implementing this option.
633 9. Fixed the dumping and restoring of files with holes
634 (files ending with holes didn't get dumped or restored
637 10. Fixed a socket descriptor leak in dump, which leaved opened
638 3 file descriptors per dump process (and there is one dump
641 11. Fixed dump large file system support, by explicit use of
642 open64/lseek64/etc functions (explicit use needed because
643 e2fsprogs libraries don't behave well when compiled with
644 FILE_OFFSET_BITS=64).
646 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
647 ======================================================================
649 1. Fixed some bugs in the dump -w|-W logic introduced by
650 the previous version. Thanks to Andreas Dilger
651 <adilger@turbolinux.com> for his help on this one.
653 2. Fixed again a compilation problem when using old e2fs
654 headers (filesystem label related). Thanks to many users
655 who reported this stupid error.
657 3. Fixed a build problem on old lib5 based systems dealing with
658 _PATH_MNTTAB being undefined. Thanks to John Adams
659 <johna@onevista.com> for reporting the bug.
661 4. Improved the error detection in restore when creating
662 the temporary files in TMPDIR. Now restore will corectly
663 report a 'no space left on device' error instead of
664 strange errors which could imply an archive corruption.
665 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
666 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
668 5. Added the throughput information in dump's progression
669 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
672 6. Use libext2fs's inode scanning routines, which are particularly
673 robust when dealing with errors (especially when having some
674 bad blocks on the filesystem). Many thanks to Colin
675 <colin@horizon.com> for reporting the bug, investigating
676 the issues, finding a workaround, writing the patch and
677 fully testing it... (of course, if this patch will break
678 anything, he is to blame for :-)).
680 7. Made dump and restore LFS aware. Dump can dump a filesystem
681 containing large files, generate a large file on output and
682 restore can restore them. This feature is not enabled by
683 default, use --enable-largefile option of configure to enable
684 it (you need to have a LFS aware glibc though). Thanks to
685 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
686 and to Theodore T'so <tytso@valinux.com> for his always
689 8. Made dump ask upon a tape write error if it should rewrite
690 the current volume (assume this is a bad tape) or if it should
691 assume an end-of-tape condition (useful for tape drives which
692 behaves badly at the end of the tape). Thanks to Andreas
693 Dilger <adilger@turbolinux.com> for the suggestion.
695 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
696 =======================================================================
698 1. Fixed a small compilation problem due to a change
699 in the definintion of the struct sigaction in
700 glibc 2.0 / libc5. Thanks to Gunther Schlegel
701 <schlegel@riege.de> for reporting the bug and to
702 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
705 2. Modified the label and uuid analysis in order to be
706 self-contained (independant of kernel/libc headers). This
707 should fix the compile with older kernel/libc headers and
708 will preserve the functionality. Thanks to Bernhard Erdmann
709 <bernhard.erdmann@gmx.de> for reporting the bug.
711 3. The 'exclude inode' option, if applied to a directory
712 inode, excludes now correctly all the leaves of this
713 directory. Thanks to John R. Dennison
714 <gerdesas@users.sourceforge.net> for reporting the bug.
716 4. Fixed the '-e' option to disable the possibility
717 to exclude the root inode (which causes the dumps to
718 be unreadable by restore). Prevented array overflow
719 when multiple -e options are used.
721 5. Fixed dump to correctly interpret a filesystem argument
722 which is a mountpoint and it is not an absolute path
723 (as specified in the fstab). Thanks to Bernhard R. Erdmann
724 <be@berdmann.de> for reporting the bug.
726 6. Made dump able to backup files larger than 2 GB. Note that
727 dump still doesn't cope with files larger than 4 GB.
729 7. Restore the real uid and gid before invoking an external
730 RSH program (big hole when dump or restore is suid root!).
732 8. Get the values for the default tape device and the location
733 of fstab file from the system headers. Thanks to
734 Andreas Dilger <adilger@turbolinux.com> for the patch.
736 9. Made dump -w|-W report all recognized filesystems
737 present in either /etc/fstab or /etc/dumpdates, and present
738 the list in the same order as in fstab file. Thanks
739 to Andreas Dilger <adilger@turbolinux.com> for the patch.
741 10. Made dump's -a (automatic end of tape detection) the
742 default. Specifying one of -B, -c, -d or -s options will
743 override the EOM detection. Thanks to Andreas Dilger
744 <adilger@turbolinux.com> for the patch.
746 11. Save the ext2 filesystem label into the dump volume label.
747 Specifying a volume label on the command line (-L option)
748 will override this feature. Thanks to Andreas Dilger
749 <adilger@turbolinux.com> for the patch.
751 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
752 =====================================================================
754 1. Fixed the signal handling in dump (which I broke in 0.4b17)
755 which was causing several strange dump failures (dump
756 hanged or segmentation faults etc).
758 2. Specified the default blocksize in the dump man page.
760 3. Changed two info messages of restore to be written on stdout
761 instead of stderr in order to leave stderr only for errors
762 or warnings. Thanks to Stephen Atwell
763 <satwell@urbana.css.mot.com> for the suggestion.
765 4. Corrected an off by one calculation which prevented
766 dumping a directory having a 1 character name length.
767 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
768 for reporting the bug.
770 5. Reinforce dump in order to allow only level 0 and no
771 -u option when dumping a subdirectory, and document
772 this in the man page. Thanks to Bernhard Erdmann
773 <bernhard.erdmann@gmx.de> for reporting the bug.
775 6. Fixed a small harmless bug in restore which caused
776 in some conditions hard links to be restored several
777 times (therefore generation some warning messages).
778 Thanks to Kenneth Porter <shiva@well.com> for
781 7. Updated the RPM spec file to the latest RedHat version,
782 providing FHS packaging and other cosmetic changes.
783 You will need RPM version >= 3.0.5 in order to build the RPM.
785 8. Updated the configure script to check for libtermcap
786 before checking for libreadline, because we need this
787 library in order to compile the readline support.
789 9. Made dump understand the LABEL= and UUID= notation
790 both in /etc/fstab and on the command line. Note that
791 you will need the /proc filesystem in order to use
792 these notations. Thanks to Erik Troan <ewt@redhat.com>
793 for providing the patch.
795 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
796 ===================================================================
798 1. Fixed a potential buffer overflow in restore. Thanks
799 to Stan Bubrouski <satan@fastdial.net> for reporting
802 2. Fixed a readline-related bug which prevented
803 'cat DUMPFILE | restore -i -f -' from working. Thanks
804 to Charles Karney <karney@users.sourceforge.net>
807 3. Changed a few "panic" into "exit", causing restore to
808 be more stable against some attacks (like the last one
809 reported on Bugtraq, although the last version of restore
810 was not vulnerable - just dumped core). Thanks to
811 Andreas Hasenack <andreas@conectiva.com.br> for reporting
814 4. Removed the suid-root bit on dump and restore in the
815 default build (and generated RPMs). It should be safer
816 now. Users who need the suid-root capabilities in order
817 to make network backups should read first the man page
818 of dump and enable the suid bit manually.
820 5. Added -ltermcap to the compile parameters for restore
821 when using readline support, in order to make the compile
822 process work on some systems (SuSE ?). Thanks to
823 Patrik Schindler <poc@pocnet.net> for reporting the bug.
825 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
826 ====================================================================
828 1. The -F script is called now *only* at the end of a tape,
829 not at the end of the dump. Thanks to Christian Haul
830 <haul@informatik.tu-darmstadt.de> for the bug report.
832 Normally, the device name and the current volume number
833 are passed on the command line of the script. However,
834 if you want the old style script (with no arguments
835 passed on the command line), you can enable it in
836 configure with the --enable-oldstylefscript.
838 2. Use posix signal handling to preserve dump functionality
839 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
842 3. Made the exit code of restore in case of a 'C'ompare
843 command reflect the result of the compare. An exit status
844 of 0 means the dump archive is correct, 1 means tape errors,
845 2 means that some files were modified. Thanks to Kenneth Porter
846 <shiva@well.com> for the suggestion.
848 4. Made (finally) quotes work in interactive restore.
850 5. Small fixes in order to allow dump to compile with a
851 really old e2fsprogs version. Thanks to Ian Zimmerman
852 <itz@speakeasy.org> for the bug report.
854 6. Add GNU readline capabilities to interactive restore.
855 Use configure's --enable-readline flag to enable this feature.
856 Thanks to Patrik Schindler <poc@pocnet.net> for the
859 7. Do the compare on the fly in restore 'C' mode (this will
860 allow not to exhaust the available /tmp space when
861 ccmparing large files). Thanks to Kenneth Porter
862 <shiva@well.com> for the suggestion.
864 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
865 ====================================================================
867 1. Fixed some several duplicate 'DUMP: DUMP:' in the
870 2. Corrected the estimation of blocks to dump. Note that
871 this is still wrong for large directory inodes, due
872 to the size of a BSD directory entry on the tape
873 (estimation is based on the size of the ext2 directory,
874 which is smaller because it doesn't contain the null
875 character at the end).
877 3. Made dump report the total number of MB written to
878 tape at the end of run. Thanks to W. Reilly Cooley
879 <wcooley@nakedape.cc> for the patch.
881 4. Added the -X option to restore giving the possibility
882 to read the names of the files to be extracted/listed
883 from a text file (in addition of the command line).
884 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
887 5. Added the device name and the current volume number
888 as arguments to the end of tape script (dump -F option).
890 6. Made the multi-volume dump work again (after having
891 broken it in 0.4b15).
893 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
894 ===================================================================
896 1. Added a prompt command in interactive restore mode. Thanks
897 to Andreas Dilger <adilger@home.com> for the patch.
899 2. Fixed a buffer overflow problem in dump (caused by
900 not checking the size of the filesystem parameter).
901 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
902 reporting this on Bugtraq (and to several dump users
903 who forwarded me his mail).
905 3. Added the '-F script' option to dump in order to
906 launch a script at the end of each tape (to be used
907 with a tape changer, or to notify the sysadmin by
910 4. Fixed a bug in restore compare code caused by the changes
913 5. Fixed the treatment of options using the old BSD syntax
914 in both dump and restore.
916 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
917 =======================================================================
919 1. Fixed a bug in dump which may have caused invalid deleted
920 directories to be dumped out if they were deleted after the
921 mapping pass. This could occure on active filesystem and lead
922 to heap corruption (causing dump malfunction in many possible ways).
923 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
924 bug and submitting the patch.
926 2. Fixed the handling of the filesystem parameter in dump. A
927 '/mnt/disk' parameter caused the disk contents to be dumped,
928 but a '/mnt/disk/' parameter caused the mountpoint directory
929 to be dumped (generally an empty directory).
931 3. Improved the output of dump in order to tell which directory
932 it is currently dumping (when dumping a subtree).
934 4. Added the '-e' exclude inode option to dump. Thanks to
935 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
937 5. Added a REPORTING-BUGS file in order to provide a guide
938 on how to correctly report a bug in dump/restore.
940 6. Fixed a restore problem when restoring a hard link to an inode
941 having the immutable or append-only attribute set. Thanks to
942 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
944 7. Fixed a compatibility problem between dumps made on little
945 endian machines (the format was correct) and big endian
946 machines (the format was incorrect). This fix break the
947 compatibility with the older dumps made on big endian
948 machines (sparc, m86k, ppc etc). For the first time in
949 linux dump's history (I believe), the dumps made by *BSD,
950 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
951 so interchangeable. Thanks to Rob Cermak
952 <cermak@ahab.rutgers.edu> for submitting the bug and
953 helping me test the fix.
955 8. Fixed the way dump reports the remaining percent/time, if
956 the number of blocks actually dumped exceeds the estimated
957 number of blocks. Thanks to Jean-Paul van der Jagt
958 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
960 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
961 ======================================================================
963 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
964 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
966 2. Removed the requirement to build the RPM as root from the
967 spec file. Thanks to Christian Weisgerber
968 <naddy@mips.rhein-neckar.de> for submitting this.
970 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
971 causing dump to block when dumping really huge filesystems.
972 Many thanks to Patrik Schindler <poc@pocnet.net> for
973 helping me find this bug.
975 4. Fixed the treatment for an interrupt signal when dump access
976 the remote tape through RSH. Thanks to Christian Weisgerber
977 <naddy@mips.rhein-neckar.de> for providing the patch.
979 5. Fixed a bug which was causing dump/restore to display
980 garbage characters instead of the remote host name.
982 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
983 =====================================================================
985 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
986 <kukuk@suse.de> for submitting the patch.
988 2. Fix for the exit code when using the size estimate option of
989 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
990 submitting the patch.
992 3. Handle EINTR in atomical reads/writes in dump, which was causing
993 dump to fail on some systems. Thanks to Eric Jergensen
994 <eric@dvns.com> for reporting the bug and submitting the patch.
996 4. Handle more than 16 characters for the device names in dumpdates.
997 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
998 tracking down the problem and proposing the solution.
1000 5. Fixed a bug in dump which prevented the creation of the
1001 dumpdates file when doing a 0-level dump without already
1002 having a dumpdates file. Thanks to Patrik Schindler
1003 <poc@pocnet.net> for reporting the bug.
1005 6. Changed the way dump 'S' flag reports the size estimate
1006 from number of blocks into bytes (making it compatible
1007 with the Solaris version, and simplifying things for
1008 amanda users). Thanks to Jason L Tibbitts III
1009 <tibbs@math.uh.edu> for reporting the bug.
1011 7. Fixed a compatibility problem in linux/alpha dump tape format.
1012 Now the linux/alpha dump are (again) compatible with the
1013 other dump formats. But this breaks compatibility with
1014 older dumps made on alpha. Thanks to Mike Tibor
1015 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1017 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1018 ======================================================================
1020 1. Added a '--enable-kerberos' to configure.
1022 2. Added a 'S' option to dump which determines the amount of space
1023 that is needed to perform the dump without actually doing it, similar
1024 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1025 <cermak@ahab.rutgers.edu>.
1027 3. Added a 'M' multi-volume option to dump and restore which enables
1028 dumping to multiple files (useful when dumping to an ext2
1029 partition to make several dump files in order to bypass the 2GB
1030 file size limitation). The 'f' argument is treated as a prefix and
1031 the output files will be named <prefix>001, <prefix>002 etc. With
1032 the 'M' flag, restore automatically selects the right file without
1033 asking to enter a new tape each time.
1035 4. Fixed a memory leak which was causing dump to grow very big
1036 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1037 Fearon <jasonf@netrider.org.au> for reporting the bug.
1039 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1040 ======================================================================
1042 1. Make configure test if the system glob routines support
1043 extended syntax (ALTDIRFUNC). If not, use the internal glob
1044 routines instead of system ones. Thanks to Bernhard Sadlowski
1045 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1046 and helping me resolve this and other minor libc5 compiling
1049 2. Fix a problem when dumping a ext2fs with the 'filetype'
1050 feature enabled. Thanks to Patrick J. LoPresti
1051 <patl@cag.lcs.mit.edu> for reporting the bug and to
1052 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1054 3. Made the nodump flag work on directories. A directory which
1055 has the nodump flag gets never dumped, regardless of its
1058 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1059 which allows dump on an active ext3 filesystem. However, this
1060 is a "quick and dirty" patch which enables backup of an ext3
1061 filesystem through the ext2 compatibility (by ignoring the
1062 NEEDS_RECOVERY bit). The journal file is not recognized and
1063 it is dumped (it should not).
1065 5. Test the superblock compatibility flags when dumping, in order
1066 to be sure that we know how to deal with specific features.
1068 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1069 ====================================================================
1071 1. Use lchown instead of chown, fixing a possible security problem
1072 when restoring symlinks (a malicious user could use this
1073 to deliberately corrupt the ownership of important system files).
1074 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1075 this and providing the patch.
1077 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1078 ====================================================================
1080 1. Put dump sources under CVS, added Id tags in all files so
1081 one can use 'ident' on binary files.
1083 2. Added the dump/restore version in the usage text so one can
1084 easily verify the version he is using.
1086 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1087 a va_start/va_end problem on linux-ppc (always call va_start
1088 va_end in pairs each time we use a vararg function).
1090 4. Added again the DT_* constants because old libc does not
1091 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1092 for submitting the bug report.
1094 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1095 this should enable dumping big (huge) filesystems.
1097 6. Added the RSH environment variable in order to be able to
1098 use a rsh replacement like ssh when doing remote backups (and
1099 bypass the security limitations of rcmd). Now you can do remote
1100 backups without being root (or making dump setuid root).
1102 7. Modified again the way dumpdates works. For incremental dumps,
1103 we need to read dumpdates even if we are not using 'u' option.
1104 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1107 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1108 ===================================================================
1110 1. Removed the 'k' flag from the restore 'about' text if kerberos
1111 was not compiled in.
1113 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1114 to them (fsetflags takes a char*, setflags an open fd!).
1116 3. (f)setflags is called only if the flags aren't empty. If the
1117 file is a special file, a warning is printed, because changing
1118 flags implies opening the device. Normally, a special file
1119 should not have any flag... (Debian bug #29775, patch provided
1120 by Abhijit Dasgupta <abhijit@ans.net>).
1122 4. Made possible to dump a file system not mentioned in /etc/fstab.
1123 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1125 5. Changed the default behaviour to not create dumpdates
1126 unless 'u' option is specified. Removed the old "debian-patch"
1127 which provided the same thing. (Debian bug #38136, #33818).
1129 6. Removed all those dump*announce, since they were getting old...
1131 7. Added warning messages if dumpdates does not exist and
1132 when an inferior level dump does not exist (except for a level 0
1135 8. Debugged the glob calls in interactive mode: restore used a
1136 dirent struct which was different from the /usr/include/dirent.h
1137 one (this used to work, is it a glibc2 change?), so none of the
1138 compat glob (which used /usr/include/dirent.h) or the system glob
1139 worked. Restore use now the system dirent (and the system
1140 DT_* constants), which are compatible with BSD ones.
1142 9. Added a configure flag (--with-dumpdatespath) to specify
1143 the location of dumpdates file. By default, it is
1146 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1147 included the current date/version in man pages.
1149 11. Corrected the estimation of remaining time when
1150 the operator doesn't change the tapes quickly enough. This
1151 was an old bug, I thought I corrected it, and discovered
1152 that in fact it was corrected in two different places, so
1153 the results canceled each other...
1155 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1156 ===================================================================
1158 1. Integrated multiple patches from RedHat, Debian and SuSE:
1160 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1162 - several fixes in the man pages.
1163 - update the default tape device to /dev/st0.
1164 - many updates for Linux Alpha (byte ordering, size_t etc).
1166 - use environment variable for TMPDIR (instead of /tmp).
1167 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1168 - workaround egcs bug (RedHat bugs #4281 and #2989).
1169 - wire $(OPT) throughout Makefile's.
1171 2. Upgrade the dump revision to 1, making possible to dump filesystems
1172 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1174 3. Fix some compile warnings, prototype all functions.
1176 4. Use glibc err/glob instead of internal compatibility
1177 routines (only if available).
1179 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1180 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1182 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1183 ======================================================================
1185 1. Integrated the changes from FreeBSD-3.1-RELEASE
1186 (mostly bug fixes, buffer overruns, dump has now an "automatic
1187 tape length calculation" flag, dump/restore can use kerberos now
1188 (this is NOT tested), use environment variables for TAPE and
1191 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1193 3. Corrected a bug in restore when using 'C' option with multi-volumes
1194 tapes (files splited accros two tapes give "size changed" errors
1197 4. Corrected the long standing bug when dumping multiple tapes.
1198 This works for me, needs further testing.
1200 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1201 ====================================================================
1203 1. Dump now runs correctly on kernels 2.1.x
1204 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1206 Changes between versions 0.4b2 and 0.4b3
1207 ========================================
1209 1. Use realpath() if available
1211 2. Report statistics
1213 Changes between versions 0.4b1 and 0.4b2
1214 ========================================
1216 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1219 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1221 3. Fixed configure.in to correctly handle --enable-rmt
1223 Changes between versions 0.3 and 0.4b1
1224 ======================================
1226 1. Integrated the changes from 4.4BSD-Lite2
1228 2. Integrated the patches from Debian and Red Hat
1230 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1232 4. Changed dump to use the Ext2fs library to get block addresses. This
1233 should solve the endianness problem on SparcLinux.
1235 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1236 distribution's one) to use autoconf
1238 6. Fixed a few minor bugs
1240 Changes between versions 0.2e and 0.2f
1241 ======================================
1243 1. Added the creation of named pipes (fifos) in restore.
1245 2. Added the -N flag in the restore manual page.
1247 3. Added the file kernel.patch which contains the llseek() optimization
1248 patch for 1.2.x kernels.
1250 4. Fixed a bug in the restoration of symbolic links: owner and group were
1253 5. Integrated some changes from FreeBSD 2.2.
1255 6. Added a call to ftruncate() after restoring each file to restore
1256 correctly files ending by a hole.
1258 Changes between versions 0.2d and 0.2e
1259 ======================================
1261 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1262 with owner = root (0) and group = root/wheel/whatever (0).
1264 Changes between versions 0.2c and 0.2d
1265 ======================================
1267 1. Dump is now able to backup 2GB+ filesystems.
1269 2. Dump and restore can now be linked as static binaries.
1271 Changes between versions 0.2b and 0.2c
1272 ======================================
1274 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1276 Changes between versions 0.2a and 0.2b
1277 ======================================
1279 1. Really fixed the bug that I should have corrected in 0.2a.
1281 2. Enabled optimization again.
1283 Changes between versions 0.2 and 0.2a
1284 =====================================
1286 1. Disabled the optimization during compilation.
1288 Changes between versions 0.1 and 0.2
1289 ====================================
1291 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1292 the fs_type field (actually, I modified the file fstab.c to make it
1293 use the mntent functions).
1295 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1296 made by dump should be readable by the BSD restore and backups made
1297 by the BSD dump should be readable by restore. Unfortunately, this
1298 means that the dump format has changed between version 0.1 and version
1301 3. Dump is now able to backup a subtree, it is no longer limited to whole
1302 filesystems like the BSD version.
1304 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1307 Changes between versions 0.0 and 0.1
1308 ====================================
1310 1. Now create links rdump and rrestore during the `make install' step.
1312 2. Linux port specific bugs added to the manual pages
1314 3. Incorrect estimation of the number of tapes blocks fixed when doing
1315 incremental backups.
1317 4. Better ls-like format in restore in interactive mode.
