3 Changes between versions 0.4b37 and 0.4b38 (released ????????????)
4 ==================================================================
6 1. Fix a couple of troff syntax bugs in the man pages.
7 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
9 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
10 ==================================================================
12 1. Added the --enable-staticz configure option which enables
13 dump and restore to be linked with static versions of
14 libz and libbz2 (and dynamic versions of all other libraries).
15 This will make Debian users happy, because libz and libbz2
16 were the only needed libraries living in /usr, all the
17 others live in /lib. In case of system emergency, it is
18 better not to have to rely on an extra filesystem.
19 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
21 2. Fix compilation on (at least the Linux Debian port to) AMD64.
22 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
23 that are also defined by <linux/types.h> (<asm/types.h>) and
26 3. Make dump's reading of the dumpdates file a bit more robust,
27 preventing dump from crashing when the dumpdates file has
28 been modified by hand.
30 4. Fixed some offset calculations in dump code which could
31 lead to "bread lseek errors" on large filesystems. Thanks
32 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
33 reporting this bug and debugging the issue.
35 5. Made dump use the blkid library when searching for devices
36 by label or uuid instead of dump's own routines.
38 6. Corrected a bug in dump where a wrong LABEL=... line in
39 /etc/fstab could prevent dump from dumping unrelated
40 filesystems. Thanks to Bruce Lowekamp
41 <lowekamp@users.sourceforge.net> for reporting the bug.
43 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
44 ====================================================================
46 1. Fixed dump compilation with old gcc versions. Thanks to
47 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
49 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
50 when compiling against a recent glibc version.
52 3. Fixed a bug in restore preventing the read of a dump tape
53 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
54 <phiggins@transzap.com> for reporting the bug and providing
57 4. Changed dump to enable the creation of volumes of different
58 sizes in a single run (make -B accept a list of values).
59 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
61 5. Use the glibc provided minor() and major() macros instead
62 of our own bitmask implementation. This should be safe for
63 when the major/minor namespace will migrate to 32 bits.
64 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
67 6. Made explicit in the dump man page that dump will not create
68 a remote file, it will only write to an already existing one.
70 7. Another try at making size estimates better again.
72 8. Put back the inconditional running of the end-of-tape
73 script which was changed in 0.434 to be run only when -M
74 or multiple -f were NOT specified. Some users rely on this
75 feature even when it is combined with -M/-f.
77 9. Fixed restore when restoring huge backups (where rstdir...
78 temporary files are over 2GB). Thanks to
79 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
80 debugging the issue and making the patch.
82 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
83 David <vrtin@users.sourceforge.net> for submitting the bug
84 and providing a test case.
86 11. Made dump work with an arbitrary integer level (no more 10
87 levels only limitation). Thanks to Matthew
88 <msvincen@midway.uchicago.edu> for the patch.
90 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
91 =======================================================================
93 1. Added a note in the dump man page saying that the default
94 blocksize can be 32 if -d is used with a high density argument.
95 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
98 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
99 LDFLAGS environment variables. Thanks to Arcady Genkin
100 <antipode@users.sourceforge.net> for reporting the bug.
102 3. Made -e/-E options of dump accept an unlimited number of inodes
103 to be excluded, rather than a hardcoded maximum. Thanks to
104 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
106 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
107 and -D_USE_BSD_SIGNAL defines in configure in order to solve
108 64bit build problems because quad_t is redifined with a
109 different signature. Thanks to Mike Harris <mharris@redhat.com>
110 for reporting this bug.
112 5. Made restore build on Solaris, making possible to
113 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
114 <uwe@ugsoft.de> for the patch.
116 6. Made an extension in the dump tape format capable of saving
117 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
118 wrote the extension and contributed the restore code back
119 into this codebase. The same extension mechanism will be
120 used in the future to save ACLs...
122 7. Made rmt work correctly with regard to QFA and local/remote
123 files and tapes. The remote access will however work only
124 when the dump provided rmt version is used. If you want to
125 use another rmt server, please do not use the QFA feature.
126 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
128 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
129 ====================================================================
131 1. Fixed the INSTALL file to reflect the actual install paths.
132 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
135 2. Fixed the configure script to only check for headers presence
136 instead of trying to compile them. This should fix issues
137 with old build environments. Thanks to Kari Lempiainen
138 <kari@funky.pp.fi> for reporting the bug.
140 3. Fixed restore to correctly ignore sockets when comparing
141 a dump (as socket cannot be properly restored anyway). Thanks
142 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
144 4. Fixed restore to correctly access the archive file (-A argument)
145 even when using a remote tape. Thanks to Fabrice Bellet
146 <fabrice@bellet.info> for reporting the bug.
148 5. Fixed (again) handling of long (largefile) seeks in rmt.
149 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
152 6. Fixed restore corner case when dealing with large block sizes
153 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
154 <fabrice@bellet.info> for reporting the bug.
156 7. Fixed a bug preventing dump to access a filesystem having
157 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
158 for reporting the bug.
160 8. Made dump store dump dates using explicit timezones, fixing a
161 problem with incremental dumps if the timezone is modified
162 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
163 the bug report and the patch.
165 9. Fixed a bug encountered when dumping individual files (not full
166 filesystems or directories) and dangling symbolic links happen
167 to be in the list of files. For as far as dump is concerned,
168 dangling symbolic links are allowed, and are dumped as is.
169 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
170 bug and providing the fix.
172 10. Fixed open and creation modes and permissions for QFA and
173 table-of-contents files in dump and restore. Thanks to
174 Philippe Troin <phil@fifi.org> for the patch.
176 11. Fixed the archive file descriptor handling enabling it to be 0.
177 This can happen in some cases when shell redirections are used.
178 Thanks to Philippe Troin <phil@fifi.org> for the patch.
180 12. Delayed the opening of archive file until after suid had been
181 dropped (fixing a possible security issue if dump is suid).
182 Thanks to Philippe Troin <phil@fifi.org> for the patch.
184 13. Fixed the 'S' command handling in the rmt client part.
185 Thanks to Philippe Troin <phil@fifi.org> for the patch.
187 14. Modified the end-of-tape script handling to print out statistics
188 (and stop the timer) before launching the eot script. Also, the eot
189 script does not get run anymore when using -M (which makes sense) or
190 when multiple tapes are listed on the command line
191 (-f tape0,tape1,tapen) (which also makes sense).
192 Thanks to Philippe Troin <phil@fifi.org> for the patch.
194 15. Relicensed dump/restore under the 'revised' BSD license, as per
195 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
197 16. Added LZO compression to dump. This new compression method has
198 the advantage of being super fast, thus not killing tape streaming
199 on slow machines. Thanks to Helmut Jarausch
200 <jarausch@igpm.rwth-aachen.de> for the patch and to
201 Markus Oberhumer <markus@oberhumer.com> for giving special permission
202 to include his miniLZO project (GPL licensed) in dump/restore.
204 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
205 <ant@notatla.demon.co.uk> for reporting the bugs.
207 18. Added a special rmt version which can do encryption when writing
208 to tape. Read examples/encrypted_rmt/README for details on
209 how to enable and configure it. Thanks to Ken Lalonde
210 <ken@globalremit.com> for the patch.
212 19. Made dump work with 2.5 kernel end of tape early warning semantics.
213 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
215 20. Fixed a bug which caused dump -w|-W not to work anymore, because
216 the fs_freq and fs_passno fields in /etc/mtab are always set
217 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
220 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
221 =======================================================================
223 1. Added a note in the restore man page clarifying the question
224 'set the permissions on the current directory ?' asked by
225 restore at the end of treatment in -i and -x modes.
227 2. Fixed the endianess issues when reading compressed tapes.
228 Thanks to Dark Force <daq4th@users.sourceforge.net> for
229 reporting this bug and providing test cases.
231 3. Fixed the "ACL won't be dumped" warning message (which showed
232 an extra, unrelated error message). Thanks to Dragan Krnic
233 <dkrnic@lycos.com> for reporting this bug.
235 4. Made dump look first into /etc/mtab, then into /etc/fstab
236 when searching for filesystem paths. Also fixed some problems
237 caused by binding mounts or multiple block device mounts.
238 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
239 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
240 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
241 and #160305, Sourceforge bugs #618699 and #679832).
243 5. Made dump's -I option accept the value '0' meaning all the
244 read errors will be ignored. This can be useful when running
245 dump from unattended sessions (like cron jobs). Thanks to
246 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
248 6. Fixed the output of dump to indicate 'blocks' instead of
249 'tape blocks' in the various messages (blocks are always
250 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
251 made it clearly print the current blocksize at the start of
252 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
255 7. Made rmt understand long (largefiles) seeks.
257 8. Fixed build with very old versions of libext2fs, where
258 EXT2_FT_* constants were undefined.
260 9. Made dump accept the dumpdates path on the command line
261 (-D file option) instead of using only the hardcoded one.
262 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
265 10. Enabled rmt, LFS, readline, QFA options by default in
266 ./configure. Updated the configure process (new versions
267 of config.guess, config.sub etc).
269 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
270 =======================================================================
272 1. Changed dump to use fcntl(F_SETLK) style locking instead
273 of flock() when locking the dumpdates file. With the old
274 locking scheme, a local user having read rights on the
275 dumpdates file could be able to do a Denial of Service attack
276 on dump. In order to lock the dumpdates file with the new
277 scheme, the user would need to have write access on the file.
278 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
279 reporting the bug (originally a bugtraq post).
281 2. Fixed interactive 'ls' which caused spurious errors warnings
282 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
283 <jorgen_ostling@users.sourceforge.net> for reporting this
286 3. Fixed dump's estimate when dealing with sparse inodes.
288 4. Modified dump to allow setting a blocksize bigger than 32kB
289 (raised the limit to 1024kB), because newer hardware needs
290 this for proper operation. Thanks to Dirk Traenapp
291 <dtraenapp@users.sourceforge.net> for reporting this.
293 5. Fixed a bug causing Dump to stop and report an error if an
294 inode number in the exclude file was followed by some amount
295 of whitespace. Thanks to Jeffrey Sofferin
296 <sofferin@users.sourceforge.net> for reporting this bug.
298 6. Fixed a bug which caused restore, in some particular cases,
299 to ask some 'scary' questions and leave a bunch of RSTTMP
300 directories behind when restoring incremental tapes. Thanks
301 to Philippe Troin <phil@fifi.org> for reporting this bug and
302 providing the test cases.
304 7. Changed the wording when inodes are excluded from dump:
305 replaced 'Added inode 7 to exclude list' with
306 'Excluding inode 7 (resize inode) from dump', as suggested
307 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
309 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
310 ===================================================================
312 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
313 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
314 <eros@lamel.bo.cnr.it> for reporting the bug.
316 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
317 ===================================================================
319 1. Made dump print out the ext2 logical block number in case of a read
320 error, which can be given as an argument to debugfs' ncheck command,
321 in order to find out the affected inode. Added note about this
322 usage in dump's man page.
324 2. Fixed a problem in restore when reading tapes written on big
325 endian machines with very old versions of dump. The patch was
326 contributed by George Helffrich <george@geology.bristol.ac.uk>.
328 3. Fixed the tape length calculation when using large tapes
329 and compression. Thanks to Georg Lippold
330 <g_lippold@sourceforge.net> for reporting the bug.
332 4. Added a new set of examples in dump_on_cd_2 directory, based
333 on dump_on_cd examples but somewhat enhanced, supporting DVD
334 media, and localized in english and german. Thanks to
335 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
337 5. Made dump save 32 bit UID/GID. Internally, this was achieved
338 by switching from the old BSD inode format to the new BSD
339 inode format, which means that the tape format was changed.
340 However, since all restore versions out there should
341 transparently support both inode formats, the change should
342 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
345 6. Fixed a lot of warnings in the code shown when compiling
346 with 'gcc -W'. Thanks to Matthias Andree
347 <matthias.andree@stud.uni-dortmund.de> for reporting this.
349 7. Fixed a small markup bug in the dump man page. Thanks to
350 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
353 8. Rewrote entirely the man pages using the tmac.an macro
354 package (Linux man page format) instead of the original BSD
355 format. They should be now cleaner and easier to modify.
357 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
358 ==================================================================
360 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
361 non Linux clients were misinterpreted. The description of the problem
362 (incompatible numbering in Linux mtio opcodes) is documented at
363 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
364 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
365 providing an excellent, cross-platform replacement for rmt in his
368 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
369 which caused restore to fail when the inode maps were not entirely
370 contained on the first volume (when using really small volumes or
371 when dumping a huge number of inodes).
373 3. Fixed a problem in dump, where files in subdirectories of directories
374 that have the nodump flag set (or being excluded with -e/-E) were
375 sometimes incorrectly dumped (instead of being excluded). The original
376 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
377 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
378 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
379 help testing the patch.
381 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
382 which makes one able to pipe the output of dump, by the net, to
383 a remote CD-burner server.
385 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
386 and use GNU's symbolic syntax over rmt instead of numerical values
387 to assure multiple platform compatibility.
389 6. Documented the -d option in restore.
391 7. Added a -v (verbose) mode to dump. For now it just prints the number
392 of the inode being dumped, but this could evolve in future versions
393 to include interesting debugging output.
395 8. Added a -o flag to restore, which automatically restores the current
396 directory permissions in -i or -x mode, without asking the operator
397 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
398 and Peter Samuel <peters@e-smith.com>.
400 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
401 ====================================================================
403 1. Fixed a bug in the QFA feature which could have caused
404 a bad tape positionning on restore (causing extra delays in
405 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
407 2. Added a small note in the dump man page specifying that
408 there should be no white space between the option letter and
409 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
411 3. Made restore work with older versions of the readline library,
412 by checking in configure for several extended symbols. Restore
413 can now be compiled with a readline as old as the 2.0 release
414 (though it may be a good idea to upgrade it to a more recent
415 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
416 reporting the build failures.
418 4. Fixed a performance problem with the QFA file creation in
419 dump, which made unnecessary seeks on the tape slowing down
420 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
421 reporting this issue.
423 5. Removed the inclusion of some kernel headers in the dump
424 source, which prevented the compile in some kernel/glibc
425 headers/architecture combination. Thanks to Bdale Garbee
426 <bdale@gag.com> for reporting the bug.
428 6. Added the appropriate error message when dump fails to
429 open the output file for writing. Thanks to Amith Varghese
430 <amithv@yahoo.com> for reporting this bug.
432 7. Made restore able to understand large Solaris ufsdump tapes
433 (containing inodes bigger than 4194304). Sun have introduced
434 an "extension" to the dump tape format when dealing with
435 those inodes, which was uncorrectly handled by Linux restore.
436 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
437 providing a test case.
439 8. Added the -m parameter to dump which optimises the output for
440 inodes having been changed but not modified since the last dump
441 ('changed' and 'modified' have the meaning defined in stat(2)).
442 For those inodes, dump will save only the metadata, instead of
443 saving the entire inode contents. Inodes which are either
444 directories or have been modified since the last dump are saved
445 in a regular way. Uses of this flag must be consistent, meaning
446 that either every dump in an incremental dump set have the flag,
449 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
450 =======================================================================
452 1. Fixed behaviour of dump when exceeding resource limits
455 2. Added the -L flag to restore to allow the user to specify a
456 maximal allowed number of miscompares when using restore
457 with the -C option to check the backup.
459 3. Detailed the manual entry for the -N option of restore.
461 4. Added the -a flag to restore to make able doing unattended
462 restores in -i or -x mode (automatically walks through the
463 multiple dump volumes).
465 5. Extended the QFA mode to work with local files and/or
466 remote tapes and files. This way, restore can know in advance
467 the tape number and the offset for the inodes to extract and
468 can minimize the extraction time by seeking directly to the
471 6. Added the -A <archive> option to both dump and restore,
472 which makes dump to archive a dump table-of-contents in
473 the specified file to be used by restore to determine
474 whether a file is in the dump file that is being restored.
475 (the archive file syntax is also compatible with the
476 Solaris ufsdump generated one).
478 7. Small fix in restore making it able to read some (broken ?)
479 Solaris ufsdump tapes.
481 8. Fixed dump to correctly recognise the root filesystem when using
482 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
483 for reporting this bug.
485 9. Added the -P <file> option to restore to create a
486 Quick File Access file from an already made dump. Patch
487 contributed by Uwe Gohlke <uwe@ugsoft.de>.
489 10. Made restore compile and run on Solaris, making it a
490 possible replacement for the standard ufsrestore. Port was
491 contributed by Uwe Gohlke <uwe@ugsoft.de>.
493 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
494 =====================================================================
496 1. Added a set of backup scripts from Eugenio Diaz
497 <getnito@yahoo.com> in the examples section. It features
498 automatic (cron based) full and incremental dumping of
499 several filesystems on a separate filesystem.
501 2. Fixed a off-by-one miscalculation which disabled dumping
502 a one letter subdirectory. Thanks to Chris Siebenmann
503 <cks@utcc.utoronto.ca> for reporting the bug.
505 3. Fixed several restore bugs occuring when trying to
506 restore some missing files on the tape. Thanks to Chris
507 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
509 4. Fixed --with-ldopts configure argument passing, installing from
510 a separate object directory, makefile cleanups contributed
511 by <splite@purdue.edu>.
513 5. Fix a bug which could caused, in some conditions, the highest
514 number inode of a filesystem, to not be dumped. Many thanks
515 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
518 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
519 =======================================================================
521 1. Added a mini howto from Patrick Walsh in the examples
524 2. Minor man pages syntax corrections. Thanks to
525 Chris Danis <screechco@home.com> for reporting the bugs.
527 3. Added a script from David B. Peterson <dave@toppledwagon.com>
528 to the examples section. It features dumping several
529 filesystems to a remote tape drive upon ssh.
531 4. Added a patch provided by Richard Jones <rich@annexia.org>
532 which allows BRADEMAX (number of read errors tolerated by
533 dump) to be adjusted using the -I option.
535 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
536 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
539 6. Add the -l option to restore to specify if, when doing a
540 remote restore, the file used to access the backup is a
541 regular file (the defaults being a tape drive). Restore needs
542 to know this information when reading a remote compressed
543 dump. Previously, this information was autodetected, but
544 the autodetection code fails (with ioctl: Inappropriate ioctl
545 for device) when using a non Linux remote box. Thanks to
546 many users and especially to Eros Albertazzi
547 <eros@lamel.bo.cnr.it> for reporting this.
549 7. Found a workaroung for the dump deadlock problem (3 childs
550 stuck in pause(), father in read()). The workaround seems
551 to work for me and several beta-testers. If it doesn't work
552 for you, please report back.
554 8. Updated the RPM spec file (BuildPrereq, URL etc).
556 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
557 ========================================================================
559 1. Fixed the permissions of a newly created QFA file by dump.
561 2. Cleaned up the source of dump (the external variables
562 definition was a complete mess, making possible to have
565 3. Fixed restore to use the full tape volume path when doing
566 a compare (since it changes the working directory to the
567 filesystem being compared in the process).
569 4. Added the -q option to dump which makes dump abort
570 whenever it needs operator attention. It should be
571 easier to use dump in scripts with this option.
573 5. Detect the use of incompatible options to dump and
574 refuse them (like -a and -B options together).
576 6. Added bzip2 compression to dump/restore (use option -j level
577 to select it). Note that you will need a restore version
578 >= 0.4b24 in order to restore a bzip2 compressed dump.
579 The same warning as for the zlib compression applies:
580 the tape format of a bzip2 dump is not compatible with the
581 original BSD tape format.
583 7. Fixed a overflow problem in dump corrupting the dump when
584 very large files were encountered. Thanks to Vladimir Nadvornik
587 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
588 kernel buffer/page cache before starting the dump, helping
589 a bit those who use dump on mounted filesystems. Thanks to
590 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
593 9. Updated the RPM spec file following the RedHat changes
594 (dynamically linked binaries now in /usr/sbin etc).
596 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
597 which enables restore to recognise multi volume compressed dumps
598 done on CD. Included his scripts for dump (which pipe the dump
599 output directly into cdrecord) and restore. There is now
600 possible to to backups to CD on the fly!
602 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
603 ===================================================================
605 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
606 Marcus Meissner (Caldera International Security Dept.).
608 2. Implement the Sun rmt extended protocol. Patch submitted
609 by Ian Gordon <iangordon@users.sourceforge.net>.
611 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
612 the linux kernel header. This ensures that dump always has the
613 latest version of this file. Patch submitted by
614 Andreas Dilger <adilger@turbolinux.com>.
616 4. Report any filesystem present in either /etc/fstab with a
617 positive passno or /etc/dumpdates in dump -w output.
618 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
620 5. Fixed the looping problem in dump introduced in the
623 6. Changed the -B option of dump to limit the size of
624 _compressed_ output per volume if compression is on.
625 Patch contributed by Helmut Jarausch
626 <jarausch@igpm.rwth-aachen.de>. Note however that, since
627 it is impossible to predict the size of the compressed
628 data before doing the compression, the -B limit is a bit
631 7. Fixed a bug in reading the operator typed file/tape path for
632 the next volume in restore.
634 8. Implemented a "-F script" option to restore which permits the
635 user to specify a script which will be launched at the
636 beginning of each tape, useful for automatic programming of
637 tape changers for example. See the restore man page for the
638 script parameters and return codes.
640 9. Small fix for the QFA routines provided by Uwe Gohlke
641 <uwe@ugsoft.de>, and some recommendations for QFA uses in
644 10. Fixed the multivolume restoring where making a mistake
645 to the 'Mount next tape' prompt caused several blocks to
648 11. Enhanced the -e option of dump to take as a parameter a
649 comma separated list of inode numbers.
651 12. Added the -E option to dump which specify a file containing
652 inode numbers to exclude from the dump.
654 13. Fixed the compressed multi-volume dump + restore.
656 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
657 ==================================================================
659 1. Made dump report the number of blocks dumped per volume.
660 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
662 2. Fix a bug in dump where waiting too much at the 'change volumes'
663 question caused the volume to be rewritten. Thanks to
664 Graham Reed <greed@users.sourceforge.net> for reporting the
665 bug and providing a patch.
667 3. Added a compression option to dump, contributed by Jerry
668 Peters <gapeters@worldnet.att.net>.
670 WARNING: the compression works only on files/pipes and
671 drives supporting variable block size.
673 WARNING2: tapes created using the compression feature are
674 incompatible with the standard dump tape format, and a
675 version of restore >= 0.4b22 will be needed for extraction.
677 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
678 architectures. Thanks to Paul Slootman <paul@debian.org> for
679 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
682 5. Many cleanups (CPP defines, const char warnings, check of
683 ext2fs COMPAT flags, time_t cleanups, added libext2 version
684 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
686 6. Made --prefix option work in configure. All the install path
687 are now based on the configure parameters.
689 7. Added the Quick File Access mode in dump/restore, contributed
690 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
691 a file tape position for each inode, and this file is used by
692 restore (if called with parameter Q and the filename)
693 to directly position the tape at the file restore is currently
694 working on. This saves hours when restoring single files from
695 large backups, saves the tapes and the drive's head. Use
696 --enable-qfa option of configure to compile in the QFA support.
698 8. Added the possibility to dump several files and directories
699 in a single invocation of dump. Thanks to Uwe Gohlke
700 <uwe@ugsoft.de> for implementing this option.
702 9. Fixed the dumping and restoring of files with holes
703 (files ending with holes didn't get dumped or restored
706 10. Fixed a socket descriptor leak in dump, which leaved opened
707 3 file descriptors per dump process (and there is one dump
710 11. Fixed dump large file system support, by explicit use of
711 open64/lseek64/etc functions (explicit use needed because
712 e2fsprogs libraries don't behave well when compiled with
713 FILE_OFFSET_BITS=64).
715 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
716 ======================================================================
718 1. Fixed some bugs in the dump -w|-W logic introduced by
719 the previous version. Thanks to Andreas Dilger
720 <adilger@turbolinux.com> for his help on this one.
722 2. Fixed again a compilation problem when using old e2fs
723 headers (filesystem label related). Thanks to many users
724 who reported this stupid error.
726 3. Fixed a build problem on old lib5 based systems dealing with
727 _PATH_MNTTAB being undefined. Thanks to John Adams
728 <johna@onevista.com> for reporting the bug.
730 4. Improved the error detection in restore when creating
731 the temporary files in TMPDIR. Now restore will corectly
732 report a 'no space left on device' error instead of
733 strange errors which could imply an archive corruption.
734 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
735 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
737 5. Added the throughput information in dump's progression
738 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
741 6. Use libext2fs's inode scanning routines, which are particularly
742 robust when dealing with errors (especially when having some
743 bad blocks on the filesystem). Many thanks to Colin
744 <colin@horizon.com> for reporting the bug, investigating
745 the issues, finding a workaround, writing the patch and
746 fully testing it... (of course, if this patch will break
747 anything, he is to blame for :-)).
749 7. Made dump and restore LFS aware. Dump can dump a filesystem
750 containing large files, generate a large file on output and
751 restore can restore them. This feature is not enabled by
752 default, use --enable-largefile option of configure to enable
753 it (you need to have a LFS aware glibc though). Thanks to
754 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
755 and to Theodore T'so <tytso@valinux.com> for his always
758 8. Made dump ask upon a tape write error if it should rewrite
759 the current volume (assume this is a bad tape) or if it should
760 assume an end-of-tape condition (useful for tape drives which
761 behaves badly at the end of the tape). Thanks to Andreas
762 Dilger <adilger@turbolinux.com> for the suggestion.
764 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
765 =======================================================================
767 1. Fixed a small compilation problem due to a change
768 in the definintion of the struct sigaction in
769 glibc 2.0 / libc5. Thanks to Gunther Schlegel
770 <schlegel@riege.de> for reporting the bug and to
771 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
774 2. Modified the label and uuid analysis in order to be
775 self-contained (independant of kernel/libc headers). This
776 should fix the compile with older kernel/libc headers and
777 will preserve the functionality. Thanks to Bernhard Erdmann
778 <bernhard.erdmann@gmx.de> for reporting the bug.
780 3. The 'exclude inode' option, if applied to a directory
781 inode, excludes now correctly all the leaves of this
782 directory. Thanks to John R. Dennison
783 <gerdesas@users.sourceforge.net> for reporting the bug.
785 4. Fixed the '-e' option to disable the possibility
786 to exclude the root inode (which causes the dumps to
787 be unreadable by restore). Prevented array overflow
788 when multiple -e options are used.
790 5. Fixed dump to correctly interpret a filesystem argument
791 which is a mountpoint and it is not an absolute path
792 (as specified in the fstab). Thanks to Bernhard R. Erdmann
793 <be@berdmann.de> for reporting the bug.
795 6. Made dump able to backup files larger than 2 GB. Note that
796 dump still doesn't cope with files larger than 4 GB.
798 7. Restore the real uid and gid before invoking an external
799 RSH program (big hole when dump or restore is suid root!).
801 8. Get the values for the default tape device and the location
802 of fstab file from the system headers. Thanks to
803 Andreas Dilger <adilger@turbolinux.com> for the patch.
805 9. Made dump -w|-W report all recognized filesystems
806 present in either /etc/fstab or /etc/dumpdates, and present
807 the list in the same order as in fstab file. Thanks
808 to Andreas Dilger <adilger@turbolinux.com> for the patch.
810 10. Made dump's -a (automatic end of tape detection) the
811 default. Specifying one of -B, -c, -d or -s options will
812 override the EOM detection. Thanks to Andreas Dilger
813 <adilger@turbolinux.com> for the patch.
815 11. Save the ext2 filesystem label into the dump volume label.
816 Specifying a volume label on the command line (-L option)
817 will override this feature. Thanks to Andreas Dilger
818 <adilger@turbolinux.com> for the patch.
820 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
821 =====================================================================
823 1. Fixed the signal handling in dump (which I broke in 0.4b17)
824 which was causing several strange dump failures (dump
825 hanged or segmentation faults etc).
827 2. Specified the default blocksize in the dump man page.
829 3. Changed two info messages of restore to be written on stdout
830 instead of stderr in order to leave stderr only for errors
831 or warnings. Thanks to Stephen Atwell
832 <satwell@urbana.css.mot.com> for the suggestion.
834 4. Corrected an off by one calculation which prevented
835 dumping a directory having a 1 character name length.
836 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
837 for reporting the bug.
839 5. Reinforce dump in order to allow only level 0 and no
840 -u option when dumping a subdirectory, and document
841 this in the man page. Thanks to Bernhard Erdmann
842 <bernhard.erdmann@gmx.de> for reporting the bug.
844 6. Fixed a small harmless bug in restore which caused
845 in some conditions hard links to be restored several
846 times (therefore generation some warning messages).
847 Thanks to Kenneth Porter <shiva@well.com> for
850 7. Updated the RPM spec file to the latest RedHat version,
851 providing FHS packaging and other cosmetic changes.
852 You will need RPM version >= 3.0.5 in order to build the RPM.
854 8. Updated the configure script to check for libtermcap
855 before checking for libreadline, because we need this
856 library in order to compile the readline support.
858 9. Made dump understand the LABEL= and UUID= notation
859 both in /etc/fstab and on the command line. Note that
860 you will need the /proc filesystem in order to use
861 these notations. Thanks to Erik Troan <ewt@redhat.com>
862 for providing the patch.
864 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
865 ===================================================================
867 1. Fixed a potential buffer overflow in restore. Thanks
868 to Stan Bubrouski <satan@fastdial.net> for reporting
871 2. Fixed a readline-related bug which prevented
872 'cat DUMPFILE | restore -i -f -' from working. Thanks
873 to Charles Karney <karney@users.sourceforge.net>
876 3. Changed a few "panic" into "exit", causing restore to
877 be more stable against some attacks (like the last one
878 reported on Bugtraq, although the last version of restore
879 was not vulnerable - just dumped core). Thanks to
880 Andreas Hasenack <andreas@conectiva.com.br> for reporting
883 4. Removed the suid-root bit on dump and restore in the
884 default build (and generated RPMs). It should be safer
885 now. Users who need the suid-root capabilities in order
886 to make network backups should read first the man page
887 of dump and enable the suid bit manually.
889 5. Added -ltermcap to the compile parameters for restore
890 when using readline support, in order to make the compile
891 process work on some systems (SuSE ?). Thanks to
892 Patrik Schindler <poc@pocnet.net> for reporting the bug.
894 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
895 ====================================================================
897 1. The -F script is called now *only* at the end of a tape,
898 not at the end of the dump. Thanks to Christian Haul
899 <haul@informatik.tu-darmstadt.de> for the bug report.
901 Normally, the device name and the current volume number
902 are passed on the command line of the script. However,
903 if you want the old style script (with no arguments
904 passed on the command line), you can enable it in
905 configure with the --enable-oldstylefscript.
907 2. Use posix signal handling to preserve dump functionality
908 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
911 3. Made the exit code of restore in case of a 'C'ompare
912 command reflect the result of the compare. An exit status
913 of 0 means the dump archive is correct, 1 means tape errors,
914 2 means that some files were modified. Thanks to Kenneth Porter
915 <shiva@well.com> for the suggestion.
917 4. Made (finally) quotes work in interactive restore.
919 5. Small fixes in order to allow dump to compile with a
920 really old e2fsprogs version. Thanks to Ian Zimmerman
921 <itz@speakeasy.org> for the bug report.
923 6. Add GNU readline capabilities to interactive restore.
924 Use configure's --enable-readline flag to enable this feature.
925 Thanks to Patrik Schindler <poc@pocnet.net> for the
928 7. Do the compare on the fly in restore 'C' mode (this will
929 allow not to exhaust the available /tmp space when
930 ccmparing large files). Thanks to Kenneth Porter
931 <shiva@well.com> for the suggestion.
933 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
934 ====================================================================
936 1. Fixed some several duplicate 'DUMP: DUMP:' in the
939 2. Corrected the estimation of blocks to dump. Note that
940 this is still wrong for large directory inodes, due
941 to the size of a BSD directory entry on the tape
942 (estimation is based on the size of the ext2 directory,
943 which is smaller because it doesn't contain the null
944 character at the end).
946 3. Made dump report the total number of MB written to
947 tape at the end of run. Thanks to W. Reilly Cooley
948 <wcooley@nakedape.cc> for the patch.
950 4. Added the -X option to restore giving the possibility
951 to read the names of the files to be extracted/listed
952 from a text file (in addition of the command line).
953 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
956 5. Added the device name and the current volume number
957 as arguments to the end of tape script (dump -F option).
959 6. Made the multi-volume dump work again (after having
960 broken it in 0.4b15).
962 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
963 ===================================================================
965 1. Added a prompt command in interactive restore mode. Thanks
966 to Andreas Dilger <adilger@home.com> for the patch.
968 2. Fixed a buffer overflow problem in dump (caused by
969 not checking the size of the filesystem parameter).
970 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
971 reporting this on Bugtraq (and to several dump users
972 who forwarded me his mail).
974 3. Added the '-F script' option to dump in order to
975 launch a script at the end of each tape (to be used
976 with a tape changer, or to notify the sysadmin by
979 4. Fixed a bug in restore compare code caused by the changes
982 5. Fixed the treatment of options using the old BSD syntax
983 in both dump and restore.
985 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
986 =======================================================================
988 1. Fixed a bug in dump which may have caused invalid deleted
989 directories to be dumped out if they were deleted after the
990 mapping pass. This could occure on active filesystem and lead
991 to heap corruption (causing dump malfunction in many possible ways).
992 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
993 bug and submitting the patch.
995 2. Fixed the handling of the filesystem parameter in dump. A
996 '/mnt/disk' parameter caused the disk contents to be dumped,
997 but a '/mnt/disk/' parameter caused the mountpoint directory
998 to be dumped (generally an empty directory).
1000 3. Improved the output of dump in order to tell which directory
1001 it is currently dumping (when dumping a subtree).
1003 4. Added the '-e' exclude inode option to dump. Thanks to
1004 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1006 5. Added a REPORTING-BUGS file in order to provide a guide
1007 on how to correctly report a bug in dump/restore.
1009 6. Fixed a restore problem when restoring a hard link to an inode
1010 having the immutable or append-only attribute set. Thanks to
1011 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1013 7. Fixed a compatibility problem between dumps made on little
1014 endian machines (the format was correct) and big endian
1015 machines (the format was incorrect). This fix break the
1016 compatibility with the older dumps made on big endian
1017 machines (sparc, m86k, ppc etc). For the first time in
1018 linux dump's history (I believe), the dumps made by *BSD,
1019 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1020 so interchangeable. Thanks to Rob Cermak
1021 <cermak@ahab.rutgers.edu> for submitting the bug and
1022 helping me test the fix.
1024 8. Fixed the way dump reports the remaining percent/time, if
1025 the number of blocks actually dumped exceeds the estimated
1026 number of blocks. Thanks to Jean-Paul van der Jagt
1027 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1029 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1030 ======================================================================
1032 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1033 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1035 2. Removed the requirement to build the RPM as root from the
1036 spec file. Thanks to Christian Weisgerber
1037 <naddy@mips.rhein-neckar.de> for submitting this.
1039 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1040 causing dump to block when dumping really huge filesystems.
1041 Many thanks to Patrik Schindler <poc@pocnet.net> for
1042 helping me find this bug.
1044 4. Fixed the treatment for an interrupt signal when dump access
1045 the remote tape through RSH. Thanks to Christian Weisgerber
1046 <naddy@mips.rhein-neckar.de> for providing the patch.
1048 5. Fixed a bug which was causing dump/restore to display
1049 garbage characters instead of the remote host name.
1051 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1052 =====================================================================
1054 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1055 <kukuk@suse.de> for submitting the patch.
1057 2. Fix for the exit code when using the size estimate option of
1058 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1059 submitting the patch.
1061 3. Handle EINTR in atomical reads/writes in dump, which was causing
1062 dump to fail on some systems. Thanks to Eric Jergensen
1063 <eric@dvns.com> for reporting the bug and submitting the patch.
1065 4. Handle more than 16 characters for the device names in dumpdates.
1066 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1067 tracking down the problem and proposing the solution.
1069 5. Fixed a bug in dump which prevented the creation of the
1070 dumpdates file when doing a 0-level dump without already
1071 having a dumpdates file. Thanks to Patrik Schindler
1072 <poc@pocnet.net> for reporting the bug.
1074 6. Changed the way dump 'S' flag reports the size estimate
1075 from number of blocks into bytes (making it compatible
1076 with the Solaris version, and simplifying things for
1077 amanda users). Thanks to Jason L Tibbitts III
1078 <tibbs@math.uh.edu> for reporting the bug.
1080 7. Fixed a compatibility problem in linux/alpha dump tape format.
1081 Now the linux/alpha dump are (again) compatible with the
1082 other dump formats. But this breaks compatibility with
1083 older dumps made on alpha. Thanks to Mike Tibor
1084 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1086 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1087 ======================================================================
1089 1. Added a '--enable-kerberos' to configure.
1091 2. Added a 'S' option to dump which determines the amount of space
1092 that is needed to perform the dump without actually doing it, similar
1093 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1094 <cermak@ahab.rutgers.edu>.
1096 3. Added a 'M' multi-volume option to dump and restore which enables
1097 dumping to multiple files (useful when dumping to an ext2
1098 partition to make several dump files in order to bypass the 2GB
1099 file size limitation). The 'f' argument is treated as a prefix and
1100 the output files will be named <prefix>001, <prefix>002 etc. With
1101 the 'M' flag, restore automatically selects the right file without
1102 asking to enter a new tape each time.
1104 4. Fixed a memory leak which was causing dump to grow very big
1105 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1106 Fearon <jasonf@netrider.org.au> for reporting the bug.
1108 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1109 ======================================================================
1111 1. Make configure test if the system glob routines support
1112 extended syntax (ALTDIRFUNC). If not, use the internal glob
1113 routines instead of system ones. Thanks to Bernhard Sadlowski
1114 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1115 and helping me resolve this and other minor libc5 compiling
1118 2. Fix a problem when dumping a ext2fs with the 'filetype'
1119 feature enabled. Thanks to Patrick J. LoPresti
1120 <patl@cag.lcs.mit.edu> for reporting the bug and to
1121 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1123 3. Made the nodump flag work on directories. A directory which
1124 has the nodump flag gets never dumped, regardless of its
1127 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1128 which allows dump on an active ext3 filesystem. However, this
1129 is a "quick and dirty" patch which enables backup of an ext3
1130 filesystem through the ext2 compatibility (by ignoring the
1131 NEEDS_RECOVERY bit). The journal file is not recognized and
1132 it is dumped (it should not).
1134 5. Test the superblock compatibility flags when dumping, in order
1135 to be sure that we know how to deal with specific features.
1137 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1138 ====================================================================
1140 1. Use lchown instead of chown, fixing a possible security problem
1141 when restoring symlinks (a malicious user could use this
1142 to deliberately corrupt the ownership of important system files).
1143 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1144 this and providing the patch.
1146 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1147 ====================================================================
1149 1. Put dump sources under CVS, added Id tags in all files so
1150 one can use 'ident' on binary files.
1152 2. Added the dump/restore version in the usage text so one can
1153 easily verify the version he is using.
1155 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1156 a va_start/va_end problem on linux-ppc (always call va_start
1157 va_end in pairs each time we use a vararg function).
1159 4. Added again the DT_* constants because old libc does not
1160 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1161 for submitting the bug report.
1163 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1164 this should enable dumping big (huge) filesystems.
1166 6. Added the RSH environment variable in order to be able to
1167 use a rsh replacement like ssh when doing remote backups (and
1168 bypass the security limitations of rcmd). Now you can do remote
1169 backups without being root (or making dump setuid root).
1171 7. Modified again the way dumpdates works. For incremental dumps,
1172 we need to read dumpdates even if we are not using 'u' option.
1173 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1176 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1177 ===================================================================
1179 1. Removed the 'k' flag from the restore 'about' text if kerberos
1180 was not compiled in.
1182 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1183 to them (fsetflags takes a char*, setflags an open fd!).
1185 3. (f)setflags is called only if the flags aren't empty. If the
1186 file is a special file, a warning is printed, because changing
1187 flags implies opening the device. Normally, a special file
1188 should not have any flag... (Debian bug #29775, patch provided
1189 by Abhijit Dasgupta <abhijit@ans.net>).
1191 4. Made possible to dump a file system not mentioned in /etc/fstab.
1192 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1194 5. Changed the default behaviour to not create dumpdates
1195 unless 'u' option is specified. Removed the old "debian-patch"
1196 which provided the same thing. (Debian bug #38136, #33818).
1198 6. Removed all those dump*announce, since they were getting old...
1200 7. Added warning messages if dumpdates does not exist and
1201 when an inferior level dump does not exist (except for a level 0
1204 8. Debugged the glob calls in interactive mode: restore used a
1205 dirent struct which was different from the /usr/include/dirent.h
1206 one (this used to work, is it a glibc2 change?), so none of the
1207 compat glob (which used /usr/include/dirent.h) or the system glob
1208 worked. Restore use now the system dirent (and the system
1209 DT_* constants), which are compatible with BSD ones.
1211 9. Added a configure flag (--with-dumpdatespath) to specify
1212 the location of dumpdates file. By default, it is
1215 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1216 included the current date/version in man pages.
1218 11. Corrected the estimation of remaining time when
1219 the operator doesn't change the tapes quickly enough. This
1220 was an old bug, I thought I corrected it, and discovered
1221 that in fact it was corrected in two different places, so
1222 the results canceled each other...
1224 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1225 ===================================================================
1227 1. Integrated multiple patches from RedHat, Debian and SuSE:
1229 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1231 - several fixes in the man pages.
1232 - update the default tape device to /dev/st0.
1233 - many updates for Linux Alpha (byte ordering, size_t etc).
1235 - use environment variable for TMPDIR (instead of /tmp).
1236 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1237 - workaround egcs bug (RedHat bugs #4281 and #2989).
1238 - wire $(OPT) throughout Makefile's.
1240 2. Upgrade the dump revision to 1, making possible to dump filesystems
1241 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1243 3. Fix some compile warnings, prototype all functions.
1245 4. Use glibc err/glob instead of internal compatibility
1246 routines (only if available).
1248 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1249 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1251 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1252 ======================================================================
1254 1. Integrated the changes from FreeBSD-3.1-RELEASE
1255 (mostly bug fixes, buffer overruns, dump has now an "automatic
1256 tape length calculation" flag, dump/restore can use kerberos now
1257 (this is NOT tested), use environment variables for TAPE and
1260 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1262 3. Corrected a bug in restore when using 'C' option with multi-volumes
1263 tapes (files splited accros two tapes give "size changed" errors
1266 4. Corrected the long standing bug when dumping multiple tapes.
1267 This works for me, needs further testing.
1269 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1270 ====================================================================
1272 1. Dump now runs correctly on kernels 2.1.x
1273 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1275 Changes between versions 0.4b2 and 0.4b3
1276 ========================================
1278 1. Use realpath() if available
1280 2. Report statistics
1282 Changes between versions 0.4b1 and 0.4b2
1283 ========================================
1285 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1288 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1290 3. Fixed configure.in to correctly handle --enable-rmt
1292 Changes between versions 0.3 and 0.4b1
1293 ======================================
1295 1. Integrated the changes from 4.4BSD-Lite2
1297 2. Integrated the patches from Debian and Red Hat
1299 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1301 4. Changed dump to use the Ext2fs library to get block addresses. This
1302 should solve the endianness problem on SparcLinux.
1304 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1305 distribution's one) to use autoconf
1307 6. Fixed a few minor bugs
1309 Changes between versions 0.2e and 0.2f
1310 ======================================
1312 1. Added the creation of named pipes (fifos) in restore.
1314 2. Added the -N flag in the restore manual page.
1316 3. Added the file kernel.patch which contains the llseek() optimization
1317 patch for 1.2.x kernels.
1319 4. Fixed a bug in the restoration of symbolic links: owner and group were
1322 5. Integrated some changes from FreeBSD 2.2.
1324 6. Added a call to ftruncate() after restoring each file to restore
1325 correctly files ending by a hole.
1327 Changes between versions 0.2d and 0.2e
1328 ======================================
1330 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1331 with owner = root (0) and group = root/wheel/whatever (0).
1333 Changes between versions 0.2c and 0.2d
1334 ======================================
1336 1. Dump is now able to backup 2GB+ filesystems.
1338 2. Dump and restore can now be linked as static binaries.
1340 Changes between versions 0.2b and 0.2c
1341 ======================================
1343 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1345 Changes between versions 0.2a and 0.2b
1346 ======================================
1348 1. Really fixed the bug that I should have corrected in 0.2a.
1350 2. Enabled optimization again.
1352 Changes between versions 0.2 and 0.2a
1353 =====================================
1355 1. Disabled the optimization during compilation.
1357 Changes between versions 0.1 and 0.2
1358 ====================================
1360 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1361 the fs_type field (actually, I modified the file fstab.c to make it
1362 use the mntent functions).
1364 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1365 made by dump should be readable by the BSD restore and backups made
1366 by the BSD dump should be readable by restore. Unfortunately, this
1367 means that the dump format has changed between version 0.1 and version
1370 3. Dump is now able to backup a subtree, it is no longer limited to whole
1371 filesystems like the BSD version.
1373 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1376 Changes between versions 0.0 and 0.1
1377 ====================================
1379 1. Now create links rdump and rrestore during the `make install' step.
1381 2. Linux port specific bugs added to the manual pages
1383 3. Incorrect estimation of the number of tapes blocks fixed when doing
1384 incremental backups.
1386 4. Better ls-like format in restore in interactive mode.
