3 Changes between versions 0.4b35 and 0.4b36 (released ?????????????????)
4 =======================================================================
6 1. Fixed dump compilation with old gcc versions. Thanks to
7 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
9 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
10 when compiling against a recent glibc version.
12 3. Fixed a bug in restore preventing the read of a dump tape
13 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
14 <phiggins@transzap.com> for reporting the bug and providing
17 4. Changed dump to enable the creation of volumes of different
18 sizes in a single run (make -B accept a list of values).
19 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
21 5. Use the glibc provided minor() and major() macros instead
22 of our own bitmask implementation. This should be safe for
23 when the major/minor namespace will migrate to 32 bits.
24 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
27 6. Made explicit in the dump man page that dump will not create
28 a remote file, it will only write to an already existing one.
30 7. Another try at making size estimates better again.
32 8. Put back the inconditional running of the end-of-tape
33 script which was changed in 0.434 to be run only when -M
34 or multiple -f were NOT specified. Some users rely on this
35 feature even when it is combined with -M/-f.
37 9. Fixed restore when restoring huge backups (where rstdir...
38 temporary files are over 2GB). Thanks to
39 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
40 debugging the issue and making the patch.
42 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
43 David <vrtin@users.sourceforge.net> for submitting the bug
44 and providing a test case.
46 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
47 =======================================================================
49 1. Added a note in the dump man page saying that the default
50 blocksize can be 32 if -d is used with a high density argument.
51 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
54 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
55 LDFLAGS environment variables. Thanks to Arcady Genkin
56 <antipode@users.sourceforge.net> for reporting the bug.
58 3. Made -e/-E options of dump accept an unlimited number of inodes
59 to be excluded, rather than a hardcoded maximum. Thanks to
60 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
62 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
63 and -D_USE_BSD_SIGNAL defines in configure in order to solve
64 64bit build problems because quad_t is redifined with a
65 different signature. Thanks to Mike Harris <mharris@redhat.com>
66 for reporting this bug.
68 5. Made restore build on Solaris, making possible to
69 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
70 <uwe@ugsoft.de> for the patch.
72 6. Made an extension in the dump tape format capable of saving
73 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
74 wrote the extension and contributed the restore code back
75 into this codebase. The same extension mechanism will be
76 used in the future to save ACLs...
78 7. Made rmt work correctly with regard to QFA and local/remote
79 files and tapes. The remote access will however work only
80 when the dump provided rmt version is used. If you want to
81 use another rmt server, please do not use the QFA feature.
82 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
84 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
85 ====================================================================
87 1. Fixed the INSTALL file to reflect the actual install paths.
88 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
91 2. Fixed the configure script to only check for headers presence
92 instead of trying to compile them. This should fix issues
93 with old build environments. Thanks to Kari Lempiainen
94 <kari@funky.pp.fi> for reporting the bug.
96 3. Fixed restore to correctly ignore sockets when comparing
97 a dump (as socket cannot be properly restored anyway). Thanks
98 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
100 4. Fixed restore to correctly access the archive file (-A argument)
101 even when using a remote tape. Thanks to Fabrice Bellet
102 <fabrice@bellet.info> for reporting the bug.
104 5. Fixed (again) handling of long (largefile) seeks in rmt.
105 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
108 6. Fixed restore corner case when dealing with large block sizes
109 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
110 <fabrice@bellet.info> for reporting the bug.
112 7. Fixed a bug preventing dump to access a filesystem having
113 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
114 for reporting the bug.
116 8. Made dump store dump dates using explicit timezones, fixing a
117 problem with incremental dumps if the timezone is modified
118 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
119 the bug report and the patch.
121 9. Fixed a bug encountered when dumping individual files (not full
122 filesystems or directories) and dangling symbolic links happen
123 to be in the list of files. For as far as dump is concerned,
124 dangling symbolic links are allowed, and are dumped as is.
125 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
126 bug and providing the fix.
128 10. Fixed open and creation modes and permissions for QFA and
129 table-of-contents files in dump and restore. Thanks to
130 Philippe Troin <phil@fifi.org> for the patch.
132 11. Fixed the archive file descriptor handling enabling it to be 0.
133 This can happen in some cases when shell redirections are used.
134 Thanks to Philippe Troin <phil@fifi.org> for the patch.
136 12. Delayed the opening of archive file until after suid had been
137 dropped (fixing a possible security issue if dump is suid).
138 Thanks to Philippe Troin <phil@fifi.org> for the patch.
140 13. Fixed the 'S' command handling in the rmt client part.
141 Thanks to Philippe Troin <phil@fifi.org> for the patch.
143 14. Modified the end-of-tape script handling to print out statistics
144 (and stop the timer) before launching the eot script. Also, the eot
145 script does not get run anymore when using -M (which makes sense) or
146 when multiple tapes are listed on the command line
147 (-f tape0,tape1,tapen) (which also makes sense).
148 Thanks to Philippe Troin <phil@fifi.org> for the patch.
150 15. Relicensed dump/restore under the 'revised' BSD license, as per
151 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
153 16. Added LZO compression to dump. This new compression method has
154 the advantage of being super fast, thus not killing tape streaming
155 on slow machines. Thanks to Helmut Jarausch
156 <jarausch@igpm.rwth-aachen.de> for the patch and to
157 Markus Oberhumer <markus@oberhumer.com> for giving special permission
158 to include his miniLZO project (GPL licensed) in dump/restore.
160 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
161 <ant@notatla.demon.co.uk> for reporting the bugs.
163 18. Added a special rmt version which can do encryption when writing
164 to tape. Read examples/encrypted_rmt/README for details on
165 how to enable and configure it. Thanks to Ken Lalonde
166 <ken@globalremit.com> for the patch.
168 19. Made dump work with 2.5 kernel end of tape early warning semantics.
169 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
171 20. Fixed a bug which caused dump -w|-W not to work anymore, because
172 the fs_freq and fs_passno fields in /etc/mtab are always set
173 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
176 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
177 =======================================================================
179 1. Added a note in the restore man page clarifying the question
180 'set the permissions on the current directory ?' asked by
181 restore at the end of treatment in -i and -x modes.
183 2. Fixed the endianess issues when reading compressed tapes.
184 Thanks to Dark Force <daq4th@users.sourceforge.net> for
185 reporting this bug and providing test cases.
187 3. Fixed the "ACL won't be dumped" warning message (which showed
188 an extra, unrelated error message). Thanks to Dragan Krnic
189 <dkrnic@lycos.com> for reporting this bug.
191 4. Made dump look first into /etc/mtab, then into /etc/fstab
192 when searching for filesystem paths. Also fixed some problems
193 caused by binding mounts or multiple block device mounts.
194 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
195 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
196 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
197 and #160305, Sourceforge bugs #618699 and #679832).
199 5. Made dump's -I option accept the value '0' meaning all the
200 read errors will be ignored. This can be useful when running
201 dump from unattended sessions (like cron jobs). Thanks to
202 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
204 6. Fixed the output of dump to indicate 'blocks' instead of
205 'tape blocks' in the various messages (blocks are always
206 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
207 made it clearly print the current blocksize at the start of
208 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
211 7. Made rmt understand long (largefiles) seeks.
213 8. Fixed build with very old versions of libext2fs, where
214 EXT2_FT_* constants were undefined.
216 9. Made dump accept the dumpdates path on the command line
217 (-D file option) instead of using only the hardcoded one.
218 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
221 10. Enabled rmt, LFS, readline, QFA options by default in
222 ./configure. Updated the configure process (new versions
223 of config.guess, config.sub etc).
225 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
226 =======================================================================
228 1. Changed dump to use fcntl(F_SETLK) style locking instead
229 of flock() when locking the dumpdates file. With the old
230 locking scheme, a local user having read rights on the
231 dumpdates file could be able to do a Denial of Service attack
232 on dump. In order to lock the dumpdates file with the new
233 scheme, the user would need to have write access on the file.
234 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
235 reporting the bug (originally a bugtraq post).
237 2. Fixed interactive 'ls' which caused spurious errors warnings
238 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
239 <jorgen_ostling@users.sourceforge.net> for reporting this
242 3. Fixed dump's estimate when dealing with sparse inodes.
244 4. Modified dump to allow setting a blocksize bigger than 32kB
245 (raised the limit to 1024kB), because newer hardware needs
246 this for proper operation. Thanks to Dirk Traenapp
247 <dtraenapp@users.sourceforge.net> for reporting this.
249 5. Fixed a bug causing Dump to stop and report an error if an
250 inode number in the exclude file was followed by some amount
251 of whitespace. Thanks to Jeffrey Sofferin
252 <sofferin@users.sourceforge.net> for reporting this bug.
254 6. Fixed a bug which caused restore, in some particular cases,
255 to ask some 'scary' questions and leave a bunch of RSTTMP
256 directories behind when restoring incremental tapes. Thanks
257 to Philippe Troin <phil@fifi.org> for reporting this bug and
258 providing the test cases.
260 7. Changed the wording when inodes are excluded from dump:
261 replaced 'Added inode 7 to exclude list' with
262 'Excluding inode 7 (resize inode) from dump', as suggested
263 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
265 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
266 ===================================================================
268 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
269 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
270 <eros@lamel.bo.cnr.it> for reporting the bug.
272 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
273 ===================================================================
275 1. Made dump print out the ext2 logical block number in case of a read
276 error, which can be given as an argument to debugfs' ncheck command,
277 in order to find out the affected inode. Added note about this
278 usage in dump's man page.
280 2. Fixed a problem in restore when reading tapes written on big
281 endian machines with very old versions of dump. The patch was
282 contributed by George Helffrich <george@geology.bristol.ac.uk>.
284 3. Fixed the tape length calculation when using large tapes
285 and compression. Thanks to Georg Lippold
286 <g_lippold@sourceforge.net> for reporting the bug.
288 4. Added a new set of examples in dump_on_cd_2 directory, based
289 on dump_on_cd examples but somewhat enhanced, supporting DVD
290 media, and localized in english and german. Thanks to
291 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
293 5. Made dump save 32 bit UID/GID. Internally, this was achieved
294 by switching from the old BSD inode format to the new BSD
295 inode format, which means that the tape format was changed.
296 However, since all restore versions out there should
297 transparently support both inode formats, the change should
298 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
301 6. Fixed a lot of warnings in the code shown when compiling
302 with 'gcc -W'. Thanks to Matthias Andree
303 <matthias.andree@stud.uni-dortmund.de> for reporting this.
305 7. Fixed a small markup bug in the dump man page. Thanks to
306 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
309 8. Rewrote entirely the man pages using the tmac.an macro
310 package (Linux man page format) instead of the original BSD
311 format. They should be now cleaner and easier to modify.
313 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
314 ==================================================================
316 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
317 non Linux clients were misinterpreted. The description of the problem
318 (incompatible numbering in Linux mtio opcodes) is documented at
319 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
320 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
321 providing an excellent, cross-platform replacement for rmt in his
324 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
325 which caused restore to fail when the inode maps were not entirely
326 contained on the first volume (when using really small volumes or
327 when dumping a huge number of inodes).
329 3. Fixed a problem in dump, where files in subdirectories of directories
330 that have the nodump flag set (or being excluded with -e/-E) were
331 sometimes incorrectly dumped (instead of being excluded). The original
332 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
333 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
334 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
335 help testing the patch.
337 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
338 which makes one able to pipe the output of dump, by the net, to
339 a remote CD-burner server.
341 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
342 and use GNU's symbolic syntax over rmt instead of numerical values
343 to assure multiple platform compatibility.
345 6. Documented the -d option in restore.
347 7. Added a -v (verbose) mode to dump. For now it just prints the number
348 of the inode being dumped, but this could evolve in future versions
349 to include interesting debugging output.
351 8. Added a -o flag to restore, which automatically restores the current
352 directory permissions in -i or -x mode, without asking the operator
353 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
354 and Peter Samuel <peters@e-smith.com>.
356 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
357 ====================================================================
359 1. Fixed a bug in the QFA feature which could have caused
360 a bad tape positionning on restore (causing extra delays in
361 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
363 2. Added a small note in the dump man page specifying that
364 there should be no white space between the option letter and
365 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
367 3. Made restore work with older versions of the readline library,
368 by checking in configure for several extended symbols. Restore
369 can now be compiled with a readline as old as the 2.0 release
370 (though it may be a good idea to upgrade it to a more recent
371 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
372 reporting the build failures.
374 4. Fixed a performance problem with the QFA file creation in
375 dump, which made unnecessary seeks on the tape slowing down
376 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
377 reporting this issue.
379 5. Removed the inclusion of some kernel headers in the dump
380 source, which prevented the compile in some kernel/glibc
381 headers/architecture combination. Thanks to Bdale Garbee
382 <bdale@gag.com> for reporting the bug.
384 6. Added the appropriate error message when dump fails to
385 open the output file for writing. Thanks to Amith Varghese
386 <amithv@yahoo.com> for reporting this bug.
388 7. Made restore able to understand large Solaris ufsdump tapes
389 (containing inodes bigger than 4194304). Sun have introduced
390 an "extension" to the dump tape format when dealing with
391 those inodes, which was uncorrectly handled by Linux restore.
392 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
393 providing a test case.
395 8. Added the -m parameter to dump which optimises the output for
396 inodes having been changed but not modified since the last dump
397 ('changed' and 'modified' have the meaning defined in stat(2)).
398 For those inodes, dump will save only the metadata, instead of
399 saving the entire inode contents. Inodes which are either
400 directories or have been modified since the last dump are saved
401 in a regular way. Uses of this flag must be consistent, meaning
402 that either every dump in an incremental dump set have the flag,
405 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
406 =======================================================================
408 1. Fixed behaviour of dump when exceeding resource limits
411 2. Added the -L flag to restore to allow the user to specify a
412 maximal allowed number of miscompares when using restore
413 with the -C option to check the backup.
415 3. Detailed the manual entry for the -N option of restore.
417 4. Added the -a flag to restore to make able doing unattended
418 restores in -i or -x mode (automatically walks through the
419 multiple dump volumes).
421 5. Extended the QFA mode to work with local files and/or
422 remote tapes and files. This way, restore can know in advance
423 the tape number and the offset for the inodes to extract and
424 can minimize the extraction time by seeking directly to the
427 6. Added the -A <archive> option to both dump and restore,
428 which makes dump to archive a dump table-of-contents in
429 the specified file to be used by restore to determine
430 whether a file is in the dump file that is being restored.
431 (the archive file syntax is also compatible with the
432 Solaris ufsdump generated one).
434 7. Small fix in restore making it able to read some (broken ?)
435 Solaris ufsdump tapes.
437 8. Fixed dump to correctly recognise the root filesystem when using
438 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
439 for reporting this bug.
441 9. Added the -P <file> option to restore to create a
442 Quick File Access file from an already made dump. Patch
443 contributed by Uwe Gohlke <uwe@ugsoft.de>.
445 10. Made restore compile and run on Solaris, making it a
446 possible replacement for the standard ufsrestore. Port was
447 contributed by Uwe Gohlke <uwe@ugsoft.de>.
449 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
450 =====================================================================
452 1. Added a set of backup scripts from Eugenio Diaz
453 <getnito@yahoo.com> in the examples section. It features
454 automatic (cron based) full and incremental dumping of
455 several filesystems on a separate filesystem.
457 2. Fixed a off-by-one miscalculation which disabled dumping
458 a one letter subdirectory. Thanks to Chris Siebenmann
459 <cks@utcc.utoronto.ca> for reporting the bug.
461 3. Fixed several restore bugs occuring when trying to
462 restore some missing files on the tape. Thanks to Chris
463 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
465 4. Fixed --with-ldopts configure argument passing, installing from
466 a separate object directory, makefile cleanups contributed
467 by <splite@purdue.edu>.
469 5. Fix a bug which could caused, in some conditions, the highest
470 number inode of a filesystem, to not be dumped. Many thanks
471 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
474 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
475 =======================================================================
477 1. Added a mini howto from Patrick Walsh in the examples
480 2. Minor man pages syntax corrections. Thanks to
481 Chris Danis <screechco@home.com> for reporting the bugs.
483 3. Added a script from David B. Peterson <dave@toppledwagon.com>
484 to the examples section. It features dumping several
485 filesystems to a remote tape drive upon ssh.
487 4. Added a patch provided by Richard Jones <rich@annexia.org>
488 which allows BRADEMAX (number of read errors tolerated by
489 dump) to be adjusted using the -I option.
491 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
492 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
495 6. Add the -l option to restore to specify if, when doing a
496 remote restore, the file used to access the backup is a
497 regular file (the defaults being a tape drive). Restore needs
498 to know this information when reading a remote compressed
499 dump. Previously, this information was autodetected, but
500 the autodetection code fails (with ioctl: Inappropriate ioctl
501 for device) when using a non Linux remote box. Thanks to
502 many users and especially to Eros Albertazzi
503 <eros@lamel.bo.cnr.it> for reporting this.
505 7. Found a workaroung for the dump deadlock problem (3 childs
506 stuck in pause(), father in read()). The workaround seems
507 to work for me and several beta-testers. If it doesn't work
508 for you, please report back.
510 8. Updated the RPM spec file (BuildPrereq, URL etc).
512 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
513 ========================================================================
515 1. Fixed the permissions of a newly created QFA file by dump.
517 2. Cleaned up the source of dump (the external variables
518 definition was a complete mess, making possible to have
521 3. Fixed restore to use the full tape volume path when doing
522 a compare (since it changes the working directory to the
523 filesystem being compared in the process).
525 4. Added the -q option to dump which makes dump abort
526 whenever it needs operator attention. It should be
527 easier to use dump in scripts with this option.
529 5. Detect the use of incompatible options to dump and
530 refuse them (like -a and -B options together).
532 6. Added bzip2 compression to dump/restore (use option -j level
533 to select it). Note that you will need a restore version
534 >= 0.4b24 in order to restore a bzip2 compressed dump.
535 The same warning as for the zlib compression applies:
536 the tape format of a bzip2 dump is not compatible with the
537 original BSD tape format.
539 7. Fixed a overflow problem in dump corrupting the dump when
540 very large files were encountered. Thanks to Vladimir Nadvornik
543 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
544 kernel buffer/page cache before starting the dump, helping
545 a bit those who use dump on mounted filesystems. Thanks to
546 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
549 9. Updated the RPM spec file following the RedHat changes
550 (dynamically linked binaries now in /usr/sbin etc).
552 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
553 which enables restore to recognise multi volume compressed dumps
554 done on CD. Included his scripts for dump (which pipe the dump
555 output directly into cdrecord) and restore. There is now
556 possible to to backups to CD on the fly!
558 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
559 ===================================================================
561 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
562 Marcus Meissner (Caldera International Security Dept.).
564 2. Implement the Sun rmt extended protocol. Patch submitted
565 by Ian Gordon <iangordon@users.sourceforge.net>.
567 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
568 the linux kernel header. This ensures that dump always has the
569 latest version of this file. Patch submitted by
570 Andreas Dilger <adilger@turbolinux.com>.
572 4. Report any filesystem present in either /etc/fstab with a
573 positive passno or /etc/dumpdates in dump -w output.
574 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
576 5. Fixed the looping problem in dump introduced in the
579 6. Changed the -B option of dump to limit the size of
580 _compressed_ output per volume if compression is on.
581 Patch contributed by Helmut Jarausch
582 <jarausch@igpm.rwth-aachen.de>. Note however that, since
583 it is impossible to predict the size of the compressed
584 data before doing the compression, the -B limit is a bit
587 7. Fixed a bug in reading the operator typed file/tape path for
588 the next volume in restore.
590 8. Implemented a "-F script" option to restore which permits the
591 user to specify a script which will be launched at the
592 beginning of each tape, useful for automatic programming of
593 tape changers for example. See the restore man page for the
594 script parameters and return codes.
596 9. Small fix for the QFA routines provided by Uwe Gohlke
597 <uwe@ugsoft.de>, and some recommendations for QFA uses in
600 10. Fixed the multivolume restoring where making a mistake
601 to the 'Mount next tape' prompt caused several blocks to
604 11. Enhanced the -e option of dump to take as a parameter a
605 comma separated list of inode numbers.
607 12. Added the -E option to dump which specify a file containing
608 inode numbers to exclude from the dump.
610 13. Fixed the compressed multi-volume dump + restore.
612 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
613 ==================================================================
615 1. Made dump report the number of blocks dumped per volume.
616 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
618 2. Fix a bug in dump where waiting too much at the 'change volumes'
619 question caused the volume to be rewritten. Thanks to
620 Graham Reed <greed@users.sourceforge.net> for reporting the
621 bug and providing a patch.
623 3. Added a compression option to dump, contributed by Jerry
624 Peters <gapeters@worldnet.att.net>.
626 WARNING: the compression works only on files/pipes and
627 drives supporting variable block size.
629 WARNING2: tapes created using the compression feature are
630 incompatible with the standard dump tape format, and a
631 version of restore >= 0.4b22 will be needed for extraction.
633 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
634 architectures. Thanks to Paul Slootman <paul@debian.org> for
635 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
638 5. Many cleanups (CPP defines, const char warnings, check of
639 ext2fs COMPAT flags, time_t cleanups, added libext2 version
640 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
642 6. Made --prefix option work in configure. All the install path
643 are now based on the configure parameters.
645 7. Added the Quick File Access mode in dump/restore, contributed
646 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
647 a file tape position for each inode, and this file is used by
648 restore (if called with parameter Q and the filename)
649 to directly position the tape at the file restore is currently
650 working on. This saves hours when restoring single files from
651 large backups, saves the tapes and the drive's head. Use
652 --enable-qfa option of configure to compile in the QFA support.
654 8. Added the possibility to dump several files and directories
655 in a single invocation of dump. Thanks to Uwe Gohlke
656 <uwe@ugsoft.de> for implementing this option.
658 9. Fixed the dumping and restoring of files with holes
659 (files ending with holes didn't get dumped or restored
662 10. Fixed a socket descriptor leak in dump, which leaved opened
663 3 file descriptors per dump process (and there is one dump
666 11. Fixed dump large file system support, by explicit use of
667 open64/lseek64/etc functions (explicit use needed because
668 e2fsprogs libraries don't behave well when compiled with
669 FILE_OFFSET_BITS=64).
671 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
672 ======================================================================
674 1. Fixed some bugs in the dump -w|-W logic introduced by
675 the previous version. Thanks to Andreas Dilger
676 <adilger@turbolinux.com> for his help on this one.
678 2. Fixed again a compilation problem when using old e2fs
679 headers (filesystem label related). Thanks to many users
680 who reported this stupid error.
682 3. Fixed a build problem on old lib5 based systems dealing with
683 _PATH_MNTTAB being undefined. Thanks to John Adams
684 <johna@onevista.com> for reporting the bug.
686 4. Improved the error detection in restore when creating
687 the temporary files in TMPDIR. Now restore will corectly
688 report a 'no space left on device' error instead of
689 strange errors which could imply an archive corruption.
690 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
691 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
693 5. Added the throughput information in dump's progression
694 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
697 6. Use libext2fs's inode scanning routines, which are particularly
698 robust when dealing with errors (especially when having some
699 bad blocks on the filesystem). Many thanks to Colin
700 <colin@horizon.com> for reporting the bug, investigating
701 the issues, finding a workaround, writing the patch and
702 fully testing it... (of course, if this patch will break
703 anything, he is to blame for :-)).
705 7. Made dump and restore LFS aware. Dump can dump a filesystem
706 containing large files, generate a large file on output and
707 restore can restore them. This feature is not enabled by
708 default, use --enable-largefile option of configure to enable
709 it (you need to have a LFS aware glibc though). Thanks to
710 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
711 and to Theodore T'so <tytso@valinux.com> for his always
714 8. Made dump ask upon a tape write error if it should rewrite
715 the current volume (assume this is a bad tape) or if it should
716 assume an end-of-tape condition (useful for tape drives which
717 behaves badly at the end of the tape). Thanks to Andreas
718 Dilger <adilger@turbolinux.com> for the suggestion.
720 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
721 =======================================================================
723 1. Fixed a small compilation problem due to a change
724 in the definintion of the struct sigaction in
725 glibc 2.0 / libc5. Thanks to Gunther Schlegel
726 <schlegel@riege.de> for reporting the bug and to
727 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
730 2. Modified the label and uuid analysis in order to be
731 self-contained (independant of kernel/libc headers). This
732 should fix the compile with older kernel/libc headers and
733 will preserve the functionality. Thanks to Bernhard Erdmann
734 <bernhard.erdmann@gmx.de> for reporting the bug.
736 3. The 'exclude inode' option, if applied to a directory
737 inode, excludes now correctly all the leaves of this
738 directory. Thanks to John R. Dennison
739 <gerdesas@users.sourceforge.net> for reporting the bug.
741 4. Fixed the '-e' option to disable the possibility
742 to exclude the root inode (which causes the dumps to
743 be unreadable by restore). Prevented array overflow
744 when multiple -e options are used.
746 5. Fixed dump to correctly interpret a filesystem argument
747 which is a mountpoint and it is not an absolute path
748 (as specified in the fstab). Thanks to Bernhard R. Erdmann
749 <be@berdmann.de> for reporting the bug.
751 6. Made dump able to backup files larger than 2 GB. Note that
752 dump still doesn't cope with files larger than 4 GB.
754 7. Restore the real uid and gid before invoking an external
755 RSH program (big hole when dump or restore is suid root!).
757 8. Get the values for the default tape device and the location
758 of fstab file from the system headers. Thanks to
759 Andreas Dilger <adilger@turbolinux.com> for the patch.
761 9. Made dump -w|-W report all recognized filesystems
762 present in either /etc/fstab or /etc/dumpdates, and present
763 the list in the same order as in fstab file. Thanks
764 to Andreas Dilger <adilger@turbolinux.com> for the patch.
766 10. Made dump's -a (automatic end of tape detection) the
767 default. Specifying one of -B, -c, -d or -s options will
768 override the EOM detection. Thanks to Andreas Dilger
769 <adilger@turbolinux.com> for the patch.
771 11. Save the ext2 filesystem label into the dump volume label.
772 Specifying a volume label on the command line (-L option)
773 will override this feature. Thanks to Andreas Dilger
774 <adilger@turbolinux.com> for the patch.
776 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
777 =====================================================================
779 1. Fixed the signal handling in dump (which I broke in 0.4b17)
780 which was causing several strange dump failures (dump
781 hanged or segmentation faults etc).
783 2. Specified the default blocksize in the dump man page.
785 3. Changed two info messages of restore to be written on stdout
786 instead of stderr in order to leave stderr only for errors
787 or warnings. Thanks to Stephen Atwell
788 <satwell@urbana.css.mot.com> for the suggestion.
790 4. Corrected an off by one calculation which prevented
791 dumping a directory having a 1 character name length.
792 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
793 for reporting the bug.
795 5. Reinforce dump in order to allow only level 0 and no
796 -u option when dumping a subdirectory, and document
797 this in the man page. Thanks to Bernhard Erdmann
798 <bernhard.erdmann@gmx.de> for reporting the bug.
800 6. Fixed a small harmless bug in restore which caused
801 in some conditions hard links to be restored several
802 times (therefore generation some warning messages).
803 Thanks to Kenneth Porter <shiva@well.com> for
806 7. Updated the RPM spec file to the latest RedHat version,
807 providing FHS packaging and other cosmetic changes.
808 You will need RPM version >= 3.0.5 in order to build the RPM.
810 8. Updated the configure script to check for libtermcap
811 before checking for libreadline, because we need this
812 library in order to compile the readline support.
814 9. Made dump understand the LABEL= and UUID= notation
815 both in /etc/fstab and on the command line. Note that
816 you will need the /proc filesystem in order to use
817 these notations. Thanks to Erik Troan <ewt@redhat.com>
818 for providing the patch.
820 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
821 ===================================================================
823 1. Fixed a potential buffer overflow in restore. Thanks
824 to Stan Bubrouski <satan@fastdial.net> for reporting
827 2. Fixed a readline-related bug which prevented
828 'cat DUMPFILE | restore -i -f -' from working. Thanks
829 to Charles Karney <karney@users.sourceforge.net>
832 3. Changed a few "panic" into "exit", causing restore to
833 be more stable against some attacks (like the last one
834 reported on Bugtraq, although the last version of restore
835 was not vulnerable - just dumped core). Thanks to
836 Andreas Hasenack <andreas@conectiva.com.br> for reporting
839 4. Removed the suid-root bit on dump and restore in the
840 default build (and generated RPMs). It should be safer
841 now. Users who need the suid-root capabilities in order
842 to make network backups should read first the man page
843 of dump and enable the suid bit manually.
845 5. Added -ltermcap to the compile parameters for restore
846 when using readline support, in order to make the compile
847 process work on some systems (SuSE ?). Thanks to
848 Patrik Schindler <poc@pocnet.net> for reporting the bug.
850 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
851 ====================================================================
853 1. The -F script is called now *only* at the end of a tape,
854 not at the end of the dump. Thanks to Christian Haul
855 <haul@informatik.tu-darmstadt.de> for the bug report.
857 Normally, the device name and the current volume number
858 are passed on the command line of the script. However,
859 if you want the old style script (with no arguments
860 passed on the command line), you can enable it in
861 configure with the --enable-oldstylefscript.
863 2. Use posix signal handling to preserve dump functionality
864 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
867 3. Made the exit code of restore in case of a 'C'ompare
868 command reflect the result of the compare. An exit status
869 of 0 means the dump archive is correct, 1 means tape errors,
870 2 means that some files were modified. Thanks to Kenneth Porter
871 <shiva@well.com> for the suggestion.
873 4. Made (finally) quotes work in interactive restore.
875 5. Small fixes in order to allow dump to compile with a
876 really old e2fsprogs version. Thanks to Ian Zimmerman
877 <itz@speakeasy.org> for the bug report.
879 6. Add GNU readline capabilities to interactive restore.
880 Use configure's --enable-readline flag to enable this feature.
881 Thanks to Patrik Schindler <poc@pocnet.net> for the
884 7. Do the compare on the fly in restore 'C' mode (this will
885 allow not to exhaust the available /tmp space when
886 ccmparing large files). Thanks to Kenneth Porter
887 <shiva@well.com> for the suggestion.
889 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
890 ====================================================================
892 1. Fixed some several duplicate 'DUMP: DUMP:' in the
895 2. Corrected the estimation of blocks to dump. Note that
896 this is still wrong for large directory inodes, due
897 to the size of a BSD directory entry on the tape
898 (estimation is based on the size of the ext2 directory,
899 which is smaller because it doesn't contain the null
900 character at the end).
902 3. Made dump report the total number of MB written to
903 tape at the end of run. Thanks to W. Reilly Cooley
904 <wcooley@nakedape.cc> for the patch.
906 4. Added the -X option to restore giving the possibility
907 to read the names of the files to be extracted/listed
908 from a text file (in addition of the command line).
909 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
912 5. Added the device name and the current volume number
913 as arguments to the end of tape script (dump -F option).
915 6. Made the multi-volume dump work again (after having
916 broken it in 0.4b15).
918 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
919 ===================================================================
921 1. Added a prompt command in interactive restore mode. Thanks
922 to Andreas Dilger <adilger@home.com> for the patch.
924 2. Fixed a buffer overflow problem in dump (caused by
925 not checking the size of the filesystem parameter).
926 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
927 reporting this on Bugtraq (and to several dump users
928 who forwarded me his mail).
930 3. Added the '-F script' option to dump in order to
931 launch a script at the end of each tape (to be used
932 with a tape changer, or to notify the sysadmin by
935 4. Fixed a bug in restore compare code caused by the changes
938 5. Fixed the treatment of options using the old BSD syntax
939 in both dump and restore.
941 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
942 =======================================================================
944 1. Fixed a bug in dump which may have caused invalid deleted
945 directories to be dumped out if they were deleted after the
946 mapping pass. This could occure on active filesystem and lead
947 to heap corruption (causing dump malfunction in many possible ways).
948 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
949 bug and submitting the patch.
951 2. Fixed the handling of the filesystem parameter in dump. A
952 '/mnt/disk' parameter caused the disk contents to be dumped,
953 but a '/mnt/disk/' parameter caused the mountpoint directory
954 to be dumped (generally an empty directory).
956 3. Improved the output of dump in order to tell which directory
957 it is currently dumping (when dumping a subtree).
959 4. Added the '-e' exclude inode option to dump. Thanks to
960 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
962 5. Added a REPORTING-BUGS file in order to provide a guide
963 on how to correctly report a bug in dump/restore.
965 6. Fixed a restore problem when restoring a hard link to an inode
966 having the immutable or append-only attribute set. Thanks to
967 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
969 7. Fixed a compatibility problem between dumps made on little
970 endian machines (the format was correct) and big endian
971 machines (the format was incorrect). This fix break the
972 compatibility with the older dumps made on big endian
973 machines (sparc, m86k, ppc etc). For the first time in
974 linux dump's history (I believe), the dumps made by *BSD,
975 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
976 so interchangeable. Thanks to Rob Cermak
977 <cermak@ahab.rutgers.edu> for submitting the bug and
978 helping me test the fix.
980 8. Fixed the way dump reports the remaining percent/time, if
981 the number of blocks actually dumped exceeds the estimated
982 number of blocks. Thanks to Jean-Paul van der Jagt
983 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
985 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
986 ======================================================================
988 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
989 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
991 2. Removed the requirement to build the RPM as root from the
992 spec file. Thanks to Christian Weisgerber
993 <naddy@mips.rhein-neckar.de> for submitting this.
995 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
996 causing dump to block when dumping really huge filesystems.
997 Many thanks to Patrik Schindler <poc@pocnet.net> for
998 helping me find this bug.
1000 4. Fixed the treatment for an interrupt signal when dump access
1001 the remote tape through RSH. Thanks to Christian Weisgerber
1002 <naddy@mips.rhein-neckar.de> for providing the patch.
1004 5. Fixed a bug which was causing dump/restore to display
1005 garbage characters instead of the remote host name.
1007 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1008 =====================================================================
1010 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1011 <kukuk@suse.de> for submitting the patch.
1013 2. Fix for the exit code when using the size estimate option of
1014 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1015 submitting the patch.
1017 3. Handle EINTR in atomical reads/writes in dump, which was causing
1018 dump to fail on some systems. Thanks to Eric Jergensen
1019 <eric@dvns.com> for reporting the bug and submitting the patch.
1021 4. Handle more than 16 characters for the device names in dumpdates.
1022 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1023 tracking down the problem and proposing the solution.
1025 5. Fixed a bug in dump which prevented the creation of the
1026 dumpdates file when doing a 0-level dump without already
1027 having a dumpdates file. Thanks to Patrik Schindler
1028 <poc@pocnet.net> for reporting the bug.
1030 6. Changed the way dump 'S' flag reports the size estimate
1031 from number of blocks into bytes (making it compatible
1032 with the Solaris version, and simplifying things for
1033 amanda users). Thanks to Jason L Tibbitts III
1034 <tibbs@math.uh.edu> for reporting the bug.
1036 7. Fixed a compatibility problem in linux/alpha dump tape format.
1037 Now the linux/alpha dump are (again) compatible with the
1038 other dump formats. But this breaks compatibility with
1039 older dumps made on alpha. Thanks to Mike Tibor
1040 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1042 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1043 ======================================================================
1045 1. Added a '--enable-kerberos' to configure.
1047 2. Added a 'S' option to dump which determines the amount of space
1048 that is needed to perform the dump without actually doing it, similar
1049 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1050 <cermak@ahab.rutgers.edu>.
1052 3. Added a 'M' multi-volume option to dump and restore which enables
1053 dumping to multiple files (useful when dumping to an ext2
1054 partition to make several dump files in order to bypass the 2GB
1055 file size limitation). The 'f' argument is treated as a prefix and
1056 the output files will be named <prefix>001, <prefix>002 etc. With
1057 the 'M' flag, restore automatically selects the right file without
1058 asking to enter a new tape each time.
1060 4. Fixed a memory leak which was causing dump to grow very big
1061 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1062 Fearon <jasonf@netrider.org.au> for reporting the bug.
1064 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1065 ======================================================================
1067 1. Make configure test if the system glob routines support
1068 extended syntax (ALTDIRFUNC). If not, use the internal glob
1069 routines instead of system ones. Thanks to Bernhard Sadlowski
1070 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1071 and helping me resolve this and other minor libc5 compiling
1074 2. Fix a problem when dumping a ext2fs with the 'filetype'
1075 feature enabled. Thanks to Patrick J. LoPresti
1076 <patl@cag.lcs.mit.edu> for reporting the bug and to
1077 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1079 3. Made the nodump flag work on directories. A directory which
1080 has the nodump flag gets never dumped, regardless of its
1083 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1084 which allows dump on an active ext3 filesystem. However, this
1085 is a "quick and dirty" patch which enables backup of an ext3
1086 filesystem through the ext2 compatibility (by ignoring the
1087 NEEDS_RECOVERY bit). The journal file is not recognized and
1088 it is dumped (it should not).
1090 5. Test the superblock compatibility flags when dumping, in order
1091 to be sure that we know how to deal with specific features.
1093 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1094 ====================================================================
1096 1. Use lchown instead of chown, fixing a possible security problem
1097 when restoring symlinks (a malicious user could use this
1098 to deliberately corrupt the ownership of important system files).
1099 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1100 this and providing the patch.
1102 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1103 ====================================================================
1105 1. Put dump sources under CVS, added Id tags in all files so
1106 one can use 'ident' on binary files.
1108 2. Added the dump/restore version in the usage text so one can
1109 easily verify the version he is using.
1111 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1112 a va_start/va_end problem on linux-ppc (always call va_start
1113 va_end in pairs each time we use a vararg function).
1115 4. Added again the DT_* constants because old libc does not
1116 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1117 for submitting the bug report.
1119 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1120 this should enable dumping big (huge) filesystems.
1122 6. Added the RSH environment variable in order to be able to
1123 use a rsh replacement like ssh when doing remote backups (and
1124 bypass the security limitations of rcmd). Now you can do remote
1125 backups without being root (or making dump setuid root).
1127 7. Modified again the way dumpdates works. For incremental dumps,
1128 we need to read dumpdates even if we are not using 'u' option.
1129 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1132 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1133 ===================================================================
1135 1. Removed the 'k' flag from the restore 'about' text if kerberos
1136 was not compiled in.
1138 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1139 to them (fsetflags takes a char*, setflags an open fd!).
1141 3. (f)setflags is called only if the flags aren't empty. If the
1142 file is a special file, a warning is printed, because changing
1143 flags implies opening the device. Normally, a special file
1144 should not have any flag... (Debian bug #29775, patch provided
1145 by Abhijit Dasgupta <abhijit@ans.net>).
1147 4. Made possible to dump a file system not mentioned in /etc/fstab.
1148 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1150 5. Changed the default behaviour to not create dumpdates
1151 unless 'u' option is specified. Removed the old "debian-patch"
1152 which provided the same thing. (Debian bug #38136, #33818).
1154 6. Removed all those dump*announce, since they were getting old...
1156 7. Added warning messages if dumpdates does not exist and
1157 when an inferior level dump does not exist (except for a level 0
1160 8. Debugged the glob calls in interactive mode: restore used a
1161 dirent struct which was different from the /usr/include/dirent.h
1162 one (this used to work, is it a glibc2 change?), so none of the
1163 compat glob (which used /usr/include/dirent.h) or the system glob
1164 worked. Restore use now the system dirent (and the system
1165 DT_* constants), which are compatible with BSD ones.
1167 9. Added a configure flag (--with-dumpdatespath) to specify
1168 the location of dumpdates file. By default, it is
1171 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1172 included the current date/version in man pages.
1174 11. Corrected the estimation of remaining time when
1175 the operator doesn't change the tapes quickly enough. This
1176 was an old bug, I thought I corrected it, and discovered
1177 that in fact it was corrected in two different places, so
1178 the results canceled each other...
1180 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1181 ===================================================================
1183 1. Integrated multiple patches from RedHat, Debian and SuSE:
1185 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1187 - several fixes in the man pages.
1188 - update the default tape device to /dev/st0.
1189 - many updates for Linux Alpha (byte ordering, size_t etc).
1191 - use environment variable for TMPDIR (instead of /tmp).
1192 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1193 - workaround egcs bug (RedHat bugs #4281 and #2989).
1194 - wire $(OPT) throughout Makefile's.
1196 2. Upgrade the dump revision to 1, making possible to dump filesystems
1197 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1199 3. Fix some compile warnings, prototype all functions.
1201 4. Use glibc err/glob instead of internal compatibility
1202 routines (only if available).
1204 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1205 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1207 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1208 ======================================================================
1210 1. Integrated the changes from FreeBSD-3.1-RELEASE
1211 (mostly bug fixes, buffer overruns, dump has now an "automatic
1212 tape length calculation" flag, dump/restore can use kerberos now
1213 (this is NOT tested), use environment variables for TAPE and
1216 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1218 3. Corrected a bug in restore when using 'C' option with multi-volumes
1219 tapes (files splited accros two tapes give "size changed" errors
1222 4. Corrected the long standing bug when dumping multiple tapes.
1223 This works for me, needs further testing.
1225 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1226 ====================================================================
1228 1. Dump now runs correctly on kernels 2.1.x
1229 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1231 Changes between versions 0.4b2 and 0.4b3
1232 ========================================
1234 1. Use realpath() if available
1236 2. Report statistics
1238 Changes between versions 0.4b1 and 0.4b2
1239 ========================================
1241 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1244 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1246 3. Fixed configure.in to correctly handle --enable-rmt
1248 Changes between versions 0.3 and 0.4b1
1249 ======================================
1251 1. Integrated the changes from 4.4BSD-Lite2
1253 2. Integrated the patches from Debian and Red Hat
1255 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1257 4. Changed dump to use the Ext2fs library to get block addresses. This
1258 should solve the endianness problem on SparcLinux.
1260 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1261 distribution's one) to use autoconf
1263 6. Fixed a few minor bugs
1265 Changes between versions 0.2e and 0.2f
1266 ======================================
1268 1. Added the creation of named pipes (fifos) in restore.
1270 2. Added the -N flag in the restore manual page.
1272 3. Added the file kernel.patch which contains the llseek() optimization
1273 patch for 1.2.x kernels.
1275 4. Fixed a bug in the restoration of symbolic links: owner and group were
1278 5. Integrated some changes from FreeBSD 2.2.
1280 6. Added a call to ftruncate() after restoring each file to restore
1281 correctly files ending by a hole.
1283 Changes between versions 0.2d and 0.2e
1284 ======================================
1286 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1287 with owner = root (0) and group = root/wheel/whatever (0).
1289 Changes between versions 0.2c and 0.2d
1290 ======================================
1292 1. Dump is now able to backup 2GB+ filesystems.
1294 2. Dump and restore can now be linked as static binaries.
1296 Changes between versions 0.2b and 0.2c
1297 ======================================
1299 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1301 Changes between versions 0.2a and 0.2b
1302 ======================================
1304 1. Really fixed the bug that I should have corrected in 0.2a.
1306 2. Enabled optimization again.
1308 Changes between versions 0.2 and 0.2a
1309 =====================================
1311 1. Disabled the optimization during compilation.
1313 Changes between versions 0.1 and 0.2
1314 ====================================
1316 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1317 the fs_type field (actually, I modified the file fstab.c to make it
1318 use the mntent functions).
1320 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1321 made by dump should be readable by the BSD restore and backups made
1322 by the BSD dump should be readable by restore. Unfortunately, this
1323 means that the dump format has changed between version 0.1 and version
1326 3. Dump is now able to backup a subtree, it is no longer limited to whole
1327 filesystems like the BSD version.
1329 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1332 Changes between versions 0.0 and 0.1
1333 ====================================
1335 1. Now create links rdump and rrestore during the `make install' step.
1337 2. Linux port specific bugs added to the manual pages
1339 3. Incorrect estimation of the number of tapes blocks fixed when doing
1340 incremental backups.
1342 4. Better ls-like format in restore in interactive mode.
