3 Changes between versions 0.4b33 and 0.4b34 (released ?????????????????)
4 =======================================================================
6 1. Fixed the INSTALL file to reflect the actual install paths.
7 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
10 2. Fixed the configure script to only check for headers presence
11 instead of trying to compile them. This should fix issues
12 with old build environments. Thanks to Kari Lempiainen
13 <kari@funky.pp.fi> for reporting the bug.
15 3. Fixed restore to correctly ignore sockets when comparing
16 a dump (as socket cannot be properly restored anyway). Thanks
17 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
19 4. Fixed restore to correctly access the archive file (-A argument)
20 even when using a remote tape. Thanks to Fabrice Bellet
21 <fabrice@bellet.info> for reporting the bug.
23 5. Fixed (again) handling of long (largefile) seeks in rmt.
24 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
27 6. Fixed restore corner case when dealing with large block sizes
28 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
29 <fabrice@bellet.info> for reporting the bug.
31 7. Fixed a bug preventing dump to access a filesystem having
32 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
33 for reporting the bug.
35 8. Made dump store dump dates using explicit timezones, fixing a
36 problem with incremental dumps if the timezone is modified
37 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
38 the bug report and the patch.
40 9. Fixed a bug encountered when dumping individual files (not full
41 filesystems or directories) and dangling symbolic links happen
42 to be in the list of files. For as far as dump is concerned,
43 dangling symbolic links are allowed, and are dumped as is.
44 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
45 bug and providing the fix.
47 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
48 =======================================================================
50 1. Added a note in the restore man page clarifying the question
51 'set the permissions on the current directory ?' asked by
52 restore at the end of treatment in -i and -x modes.
54 2. Fixed the endianess issues when reading compressed tapes.
55 Thanks to Dark Force <daq4th@users.sourceforge.net> for
56 reporting this bug and providing test cases.
58 3. Fixed the "ACL won't be dumped" warning message (which showed
59 an extra, unrelated error message). Thanks to Dragan Krnic
60 <dkrnic@lycos.com> for reporting this bug.
62 4. Made dump look first into /etc/mtab, then into /etc/fstab
63 when searching for filesystem paths. Also fixed some problems
64 caused by binding mounts or multiple block device mounts.
65 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
66 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
67 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
68 and #160305, Sourceforge bugs #618699 and #679832).
70 5. Made dump's -I option accept the value '0' meaning all the
71 read errors will be ignored. This can be useful when running
72 dump from unattended sessions (like cron jobs). Thanks to
73 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
75 6. Fixed the output of dump to indicate 'blocks' instead of
76 'tape blocks' in the various messages (blocks are always
77 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
78 made it clearly print the current blocksize at the start of
79 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
82 7. Made rmt understand long (largefiles) seeks.
84 8. Fixed build with very old versions of libext2fs, where
85 EXT2_FT_* constants were undefined.
87 9. Made dump accept the dumpdates path on the command line
88 (-D file option) instead of using only the hardcoded one.
89 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
92 10. Enabled rmt, LFS, readline, QFA options by default in
93 ./configure. Updated the configure process (new versions
94 of config.guess, config.sub etc).
96 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
97 =======================================================================
99 1. Changed dump to use fcntl(F_SETLK) style locking instead
100 of flock() when locking the dumpdates file. With the old
101 locking scheme, a local user having read rights on the
102 dumpdates file could be able to do a Denial of Service attack
103 on dump. In order to lock the dumpdates file with the new
104 scheme, the user would need to have write access on the file.
105 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
106 reporting the bug (originally a bugtraq post).
108 2. Fixed interactive 'ls' which caused spurious errors warnings
109 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
110 <jorgen_ostling@users.sourceforge.net> for reporting this
113 3. Fixed dump's estimate when dealing with sparse inodes.
115 4. Modified dump to allow setting a blocksize bigger than 32kB
116 (raised the limit to 1024kB), because newer hardware needs
117 this for proper operation. Thanks to Dirk Traenapp
118 <dtraenapp@users.sourceforge.net> for reporting this.
120 5. Fixed a bug causing Dump to stop and report an error if an
121 inode number in the exclude file was followed by some amount
122 of whitespace. Thanks to Jeffrey Sofferin
123 <sofferin@users.sourceforge.net> for reporting this bug.
125 6. Fixed a bug which caused restore, in some particular cases,
126 to ask some 'scary' questions and leave a bunch of RSTTMP
127 directories behind when restoring incremental tapes. Thanks
128 to Philippe Troin <phil@fifi.org> for reporting this bug and
129 providing the test cases.
131 7. Changed the wording when inodes are excluded from dump:
132 replaced 'Added inode 7 to exclude list' with
133 'Excluding inode 7 (resize inode) from dump', as suggested
134 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
136 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
137 ===================================================================
139 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
140 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
141 <eros@lamel.bo.cnr.it> for reporting the bug.
143 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
144 ===================================================================
146 1. Made dump print out the ext2 logical block number in case of a read
147 error, which can be given as an argument to debugfs' ncheck command,
148 in order to find out the affected inode. Added note about this
149 usage in dump's man page.
151 2. Fixed a problem in restore when reading tapes written on big
152 endian machines with very old versions of dump. The patch was
153 contributed by George Helffrich <george@geology.bristol.ac.uk>.
155 3. Fixed the tape length calculation when using large tapes
156 and compression. Thanks to Georg Lippold
157 <g_lippold@sourceforge.net> for reporting the bug.
159 4. Added a new set of examples in dump_on_cd_2 directory, based
160 on dump_on_cd examples but somewhat enhanced, supporting DVD
161 media, and localized in english and german. Thanks to
162 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
164 5. Made dump save 32 bit UID/GID. Internally, this was achieved
165 by switching from the old BSD inode format to the new BSD
166 inode format, which means that the tape format was changed.
167 However, since all restore versions out there should
168 transparently support both inode formats, the change should
169 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
172 6. Fixed a lot of warnings in the code shown when compiling
173 with 'gcc -W'. Thanks to Matthias Andree
174 <matthias.andree@stud.uni-dortmund.de> for reporting this.
176 7. Fixed a small markup bug in the dump man page. Thanks to
177 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
180 8. Rewrote entirely the man pages using the tmac.an macro
181 package (Linux man page format) instead of the original BSD
182 format. They should be now cleaner and easier to modify.
184 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
185 ==================================================================
187 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
188 non Linux clients were misinterpreted. The description of the problem
189 (incompatible numbering in Linux mtio opcodes) is documented at
190 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
191 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
192 providing an excellent, cross-platform replacement for rmt in his
195 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
196 which caused restore to fail when the inode maps were not entirely
197 contained on the first volume (when using really small volumes or
198 when dumping a huge number of inodes).
200 3. Fixed a problem in dump, where files in subdirectories of directories
201 that have the nodump flag set (or being excluded with -e/-E) were
202 sometimes incorrectly dumped (instead of being excluded). The original
203 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
204 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
205 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
206 help testing the patch.
208 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
209 which makes one able to pipe the output of dump, by the net, to
210 a remote CD-burner server.
212 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
213 and use GNU's symbolic syntax over rmt instead of numerical values
214 to assure multiple platform compatibility.
216 6. Documented the -d option in restore.
218 7. Added a -v (verbose) mode to dump. For now it just prints the number
219 of the inode being dumped, but this could evolve in future versions
220 to include interesting debugging output.
222 8. Added a -o flag to restore, which automatically restores the current
223 directory permissions in -i or -x mode, without asking the operator
224 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
225 and Peter Samuel <peters@e-smith.com>.
227 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
228 ====================================================================
230 1. Fixed a bug in the QFA feature which could have caused
231 a bad tape positionning on restore (causing extra delays in
232 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
234 2. Added a small note in the dump man page specifying that
235 there should be no white space between the option letter and
236 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
238 3. Made restore work with older versions of the readline library,
239 by checking in configure for several extended symbols. Restore
240 can now be compiled with a readline as old as the 2.0 release
241 (though it may be a good idea to upgrade it to a more recent
242 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
243 reporting the build failures.
245 4. Fixed a performance problem with the QFA file creation in
246 dump, which made unnecessary seeks on the tape slowing down
247 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
248 reporting this issue.
250 5. Removed the inclusion of some kernel headers in the dump
251 source, which prevented the compile in some kernel/glibc
252 headers/architecture combination. Thanks to Bdale Garbee
253 <bdale@gag.com> for reporting the bug.
255 6. Added the appropriate error message when dump fails to
256 open the output file for writing. Thanks to Amith Varghese
257 <amithv@yahoo.com> for reporting this bug.
259 7. Made restore able to understand large Solaris ufsdump tapes
260 (containing inodes bigger than 4194304). Sun have introduced
261 an "extension" to the dump tape format when dealing with
262 those inodes, which was uncorrectly handled by Linux restore.
263 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
264 providing a test case.
266 8. Added the -m parameter to dump which optimises the output for
267 inodes having been changed but not modified since the last dump
268 ('changed' and 'modified' have the meaning defined in stat(2)).
269 For those inodes, dump will save only the metadata, instead of
270 saving the entire inode contents. Inodes which are either
271 directories or have been modified since the last dump are saved
272 in a regular way. Uses of this flag must be consistent, meaning
273 that either every dump in an incremental dump set have the flag,
276 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
277 =======================================================================
279 1. Fixed behaviour of dump when exceeding resource limits
282 2. Added the -L flag to restore to allow the user to specify a
283 maximal allowed number of miscompares when using restore
284 with the -C option to check the backup.
286 3. Detailed the manual entry for the -N option of restore.
288 4. Added the -a flag to restore to make able doing unattended
289 restores in -i or -x mode (automatically walks through the
290 multiple dump volumes).
292 5. Extended the QFA mode to work with local files and/or
293 remote tapes and files. This way, restore can know in advance
294 the tape number and the offset for the inodes to extract and
295 can minimize the extraction time by seeking directly to the
298 6. Added the -A <archive> option to both dump and restore,
299 which makes dump to archive a dump table-of-contents in
300 the specified file to be used by restore to determine
301 whether a file is in the dump file that is being restored.
302 (the archive file syntax is also compatible with the
303 Solaris ufsdump generated one).
305 7. Small fix in restore making it able to read some (broken ?)
306 Solaris ufsdump tapes.
308 8. Fixed dump to correctly recognise the root filesystem when using
309 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
310 for reporting this bug.
312 9. Added the -P <file> option to restore to create a
313 Quick File Access file from an already made dump. Patch
314 contributed by Uwe Gohlke <uwe@ugsoft.de>.
316 10. Made restore compile and run on Solaris, making it a
317 possible replacement for the standard ufsrestore. Port was
318 contributed by Uwe Gohlke <uwe@ugsoft.de>.
320 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
321 =====================================================================
323 1. Added a set of backup scripts from Eugenio Diaz
324 <getnito@yahoo.com> in the examples section. It features
325 automatic (cron based) full and incremental dumping of
326 several filesystems on a separate filesystem.
328 2. Fixed a off-by-one miscalculation which disabled dumping
329 a one letter subdirectory. Thanks to Chris Siebenmann
330 <cks@utcc.utoronto.ca> for reporting the bug.
332 3. Fixed several restore bugs occuring when trying to
333 restore some missing files on the tape. Thanks to Chris
334 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
336 4. Fixed --with-ldopts configure argument passing, installing from
337 a separate object directory, makefile cleanups contributed
338 by <splite@purdue.edu>.
340 5. Fix a bug which could caused, in some conditions, the highest
341 number inode of a filesystem, to not be dumped. Many thanks
342 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
345 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
346 =======================================================================
348 1. Added a mini howto from Patrick Walsh in the examples
351 2. Minor man pages syntax corrections. Thanks to
352 Chris Danis <screechco@home.com> for reporting the bugs.
354 3. Added a script from David B. Peterson <dave@toppledwagon.com>
355 to the examples section. It features dumping several
356 filesystems to a remote tape drive upon ssh.
358 4. Added a patch provided by Richard Jones <rich@annexia.org>
359 which allows BRADEMAX (number of read errors tolerated by
360 dump) to be adjusted using the -I option.
362 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
363 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
366 6. Add the -l option to restore to specify if, when doing a
367 remote restore, the file used to access the backup is a
368 regular file (the defaults being a tape drive). Restore needs
369 to know this information when reading a remote compressed
370 dump. Previously, this information was autodetected, but
371 the autodetection code fails (with ioctl: Inappropriate ioctl
372 for device) when using a non Linux remote box. Thanks to
373 many users and especially to Eros Albertazzi
374 <eros@lamel.bo.cnr.it> for reporting this.
376 7. Found a workaroung for the dump deadlock problem (3 childs
377 stuck in pause(), father in read()). The workaround seems
378 to work for me and several beta-testers. If it doesn't work
379 for you, please report back.
381 8. Updated the RPM spec file (BuildPrereq, URL etc).
383 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
384 ========================================================================
386 1. Fixed the permissions of a newly created QFA file by dump.
388 2. Cleaned up the source of dump (the external variables
389 definition was a complete mess, making possible to have
392 3. Fixed restore to use the full tape volume path when doing
393 a compare (since it changes the working directory to the
394 filesystem being compared in the process).
396 4. Added the -q option to dump which makes dump abort
397 whenever it needs operator attention. It should be
398 easier to use dump in scripts with this option.
400 5. Detect the use of incompatible options to dump and
401 refuse them (like -a and -B options together).
403 6. Added bzip2 compression to dump/restore (use option -j level
404 to select it). Note that you will need a restore version
405 >= 0.4b24 in order to restore a bzip2 compressed dump.
406 The same warning as for the zlib compression applies:
407 the tape format of a bzip2 dump is not compatible with the
408 original BSD tape format.
410 7. Fixed a overflow problem in dump corrupting the dump when
411 very large files were encountered. Thanks to Vladimir Nadvornik
414 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
415 kernel buffer/page cache before starting the dump, helping
416 a bit those who use dump on mounted filesystems. Thanks to
417 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
420 9. Updated the RPM spec file following the RedHat changes
421 (dynamically linked binaries now in /usr/sbin etc).
423 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
424 which enables restore to recognise multi volume compressed dumps
425 done on CD. Included his scripts for dump (which pipe the dump
426 output directly into cdrecord) and restore. There is now
427 possible to to backups to CD on the fly!
429 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
430 ===================================================================
432 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
433 Marcus Meissner (Caldera International Security Dept.).
435 2. Implement the Sun rmt extended protocol. Patch submitted
436 by Ian Gordon <iangordon@users.sourceforge.net>.
438 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
439 the linux kernel header. This ensures that dump always has the
440 latest version of this file. Patch submitted by
441 Andreas Dilger <adilger@turbolinux.com>.
443 4. Report any filesystem present in either /etc/fstab with a
444 positive passno or /etc/dumpdates in dump -w output.
445 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
447 5. Fixed the looping problem in dump introduced in the
450 6. Changed the -B option of dump to limit the size of
451 _compressed_ output per volume if compression is on.
452 Patch contributed by Helmut Jarausch
453 <jarausch@igpm.rwth-aachen.de>. Note however that, since
454 it is impossible to predict the size of the compressed
455 data before doing the compression, the -B limit is a bit
458 7. Fixed a bug in reading the operator typed file/tape path for
459 the next volume in restore.
461 8. Implemented a "-F script" option to restore which permits the
462 user to specify a script which will be launched at the
463 beginning of each tape, useful for automatic programming of
464 tape changers for example. See the restore man page for the
465 script parameters and return codes.
467 9. Small fix for the QFA routines provided by Uwe Gohlke
468 <uwe@ugsoft.de>, and some recommendations for QFA uses in
471 10. Fixed the multivolume restoring where making a mistake
472 to the 'Mount next tape' prompt caused several blocks to
475 11. Enhanced the -e option of dump to take as a parameter a
476 comma separated list of inode numbers.
478 12. Added the -E option to dump which specify a file containing
479 inode numbers to exclude from the dump.
481 13. Fixed the compressed multi-volume dump + restore.
483 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
484 ==================================================================
486 1. Made dump report the number of blocks dumped per volume.
487 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
489 2. Fix a bug in dump where waiting too much at the 'change volumes'
490 question caused the volume to be rewritten. Thanks to
491 Graham Reed <greed@users.sourceforge.net> for reporting the
492 bug and providing a patch.
494 3. Added a compression option to dump, contributed by Jerry
495 Peters <gapeters@worldnet.att.net>.
497 WARNING: the compression works only on files/pipes and
498 drives supporting variable block size.
500 WARNING2: tapes created using the compression feature are
501 incompatible with the standard dump tape format, and a
502 version of restore >= 0.4b22 will be needed for extraction.
504 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
505 architectures. Thanks to Paul Slootman <paul@debian.org> for
506 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
509 5. Many cleanups (CPP defines, const char warnings, check of
510 ext2fs COMPAT flags, time_t cleanups, added libext2 version
511 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
513 6. Made --prefix option work in configure. All the install path
514 are now based on the configure parameters.
516 7. Added the Quick File Access mode in dump/restore, contributed
517 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
518 a file tape position for each inode, and this file is used by
519 restore (if called with parameter Q and the filename)
520 to directly position the tape at the file restore is currently
521 working on. This saves hours when restoring single files from
522 large backups, saves the tapes and the drive's head. Use
523 --enable-qfa option of configure to compile in the QFA support.
525 8. Added the possibility to dump several files and directories
526 in a single invocation of dump. Thanks to Uwe Gohlke
527 <uwe@ugsoft.de> for implementing this option.
529 9. Fixed the dumping and restoring of files with holes
530 (files ending with holes didn't get dumped or restored
533 10. Fixed a socket descriptor leak in dump, which leaved opened
534 3 file descriptors per dump process (and there is one dump
537 11. Fixed dump large file system support, by explicit use of
538 open64/lseek64/etc functions (explicit use needed because
539 e2fsprogs libraries don't behave well when compiled with
540 FILE_OFFSET_BITS=64).
542 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
543 ======================================================================
545 1. Fixed some bugs in the dump -w|-W logic introduced by
546 the previous version. Thanks to Andreas Dilger
547 <adilger@turbolinux.com> for his help on this one.
549 2. Fixed again a compilation problem when using old e2fs
550 headers (filesystem label related). Thanks to many users
551 who reported this stupid error.
553 3. Fixed a build problem on old lib5 based systems dealing with
554 _PATH_MNTTAB being undefined. Thanks to John Adams
555 <johna@onevista.com> for reporting the bug.
557 4. Improved the error detection in restore when creating
558 the temporary files in TMPDIR. Now restore will corectly
559 report a 'no space left on device' error instead of
560 strange errors which could imply an archive corruption.
561 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
562 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
564 5. Added the throughput information in dump's progression
565 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
568 6. Use libext2fs's inode scanning routines, which are particularly
569 robust when dealing with errors (especially when having some
570 bad blocks on the filesystem). Many thanks to Colin
571 <colin@horizon.com> for reporting the bug, investigating
572 the issues, finding a workaround, writing the patch and
573 fully testing it... (of course, if this patch will break
574 anything, he is to blame for :-)).
576 7. Made dump and restore LFS aware. Dump can dump a filesystem
577 containing large files, generate a large file on output and
578 restore can restore them. This feature is not enabled by
579 default, use --enable-largefile option of configure to enable
580 it (you need to have a LFS aware glibc though). Thanks to
581 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
582 and to Theodore T'so <tytso@valinux.com> for his always
585 8. Made dump ask upon a tape write error if it should rewrite
586 the current volume (assume this is a bad tape) or if it should
587 assume an end-of-tape condition (useful for tape drives which
588 behaves badly at the end of the tape). Thanks to Andreas
589 Dilger <adilger@turbolinux.com> for the suggestion.
591 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
592 =======================================================================
594 1. Fixed a small compilation problem due to a change
595 in the definintion of the struct sigaction in
596 glibc 2.0 / libc5. Thanks to Gunther Schlegel
597 <schlegel@riege.de> for reporting the bug and to
598 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
601 2. Modified the label and uuid analysis in order to be
602 self-contained (independant of kernel/libc headers). This
603 should fix the compile with older kernel/libc headers and
604 will preserve the functionality. Thanks to Bernhard Erdmann
605 <bernhard.erdmann@gmx.de> for reporting the bug.
607 3. The 'exclude inode' option, if applied to a directory
608 inode, excludes now correctly all the leaves of this
609 directory. Thanks to John R. Dennison
610 <gerdesas@users.sourceforge.net> for reporting the bug.
612 4. Fixed the '-e' option to disable the possibility
613 to exclude the root inode (which causes the dumps to
614 be unreadable by restore). Prevented array overflow
615 when multiple -e options are used.
617 5. Fixed dump to correctly interpret a filesystem argument
618 which is a mountpoint and it is not an absolute path
619 (as specified in the fstab). Thanks to Bernhard R. Erdmann
620 <be@berdmann.de> for reporting the bug.
622 6. Made dump able to backup files larger than 2 GB. Note that
623 dump still doesn't cope with files larger than 4 GB.
625 7. Restore the real uid and gid before invoking an external
626 RSH program (big hole when dump or restore is suid root!).
628 8. Get the values for the default tape device and the location
629 of fstab file from the system headers. Thanks to
630 Andreas Dilger <adilger@turbolinux.com> for the patch.
632 9. Made dump -w|-W report all recognized filesystems
633 present in either /etc/fstab or /etc/dumpdates, and present
634 the list in the same order as in fstab file. Thanks
635 to Andreas Dilger <adilger@turbolinux.com> for the patch.
637 10. Made dump's -a (automatic end of tape detection) the
638 default. Specifying one of -B, -c, -d or -s options will
639 override the EOM detection. Thanks to Andreas Dilger
640 <adilger@turbolinux.com> for the patch.
642 11. Save the ext2 filesystem label into the dump volume label.
643 Specifying a volume label on the command line (-L option)
644 will override this feature. Thanks to Andreas Dilger
645 <adilger@turbolinux.com> for the patch.
647 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
648 =====================================================================
650 1. Fixed the signal handling in dump (which I broke in 0.4b17)
651 which was causing several strange dump failures (dump
652 hanged or segmentation faults etc).
654 2. Specified the default blocksize in the dump man page.
656 3. Changed two info messages of restore to be written on stdout
657 instead of stderr in order to leave stderr only for errors
658 or warnings. Thanks to Stephen Atwell
659 <satwell@urbana.css.mot.com> for the suggestion.
661 4. Corrected an off by one calculation which prevented
662 dumping a directory having a 1 character name length.
663 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
664 for reporting the bug.
666 5. Reinforce dump in order to allow only level 0 and no
667 -u option when dumping a subdirectory, and document
668 this in the man page. Thanks to Bernhard Erdmann
669 <bernhard.erdmann@gmx.de> for reporting the bug.
671 6. Fixed a small harmless bug in restore which caused
672 in some conditions hard links to be restored several
673 times (therefore generation some warning messages).
674 Thanks to Kenneth Porter <shiva@well.com> for
677 7. Updated the RPM spec file to the latest RedHat version,
678 providing FHS packaging and other cosmetic changes.
679 You will need RPM version >= 3.0.5 in order to build the RPM.
681 8. Updated the configure script to check for libtermcap
682 before checking for libreadline, because we need this
683 library in order to compile the readline support.
685 9. Made dump understand the LABEL= and UUID= notation
686 both in /etc/fstab and on the command line. Note that
687 you will need the /proc filesystem in order to use
688 these notations. Thanks to Erik Troan <ewt@redhat.com>
689 for providing the patch.
691 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
692 ===================================================================
694 1. Fixed a potential buffer overflow in restore. Thanks
695 to Stan Bubrouski <satan@fastdial.net> for reporting
698 2. Fixed a readline-related bug which prevented
699 'cat DUMPFILE | restore -i -f -' from working. Thanks
700 to Charles Karney <karney@users.sourceforge.net>
703 3. Changed a few "panic" into "exit", causing restore to
704 be more stable against some attacks (like the last one
705 reported on Bugtraq, although the last version of restore
706 was not vulnerable - just dumped core). Thanks to
707 Andreas Hasenack <andreas@conectiva.com.br> for reporting
710 4. Removed the suid-root bit on dump and restore in the
711 default build (and generated RPMs). It should be safer
712 now. Users who need the suid-root capabilities in order
713 to make network backups should read first the man page
714 of dump and enable the suid bit manually.
716 5. Added -ltermcap to the compile parameters for restore
717 when using readline support, in order to make the compile
718 process work on some systems (SuSE ?). Thanks to
719 Patrik Schindler <poc@pocnet.net> for reporting the bug.
721 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
722 ====================================================================
724 1. The -F script is called now *only* at the end of a tape,
725 not at the end of the dump. Thanks to Christian Haul
726 <haul@informatik.tu-darmstadt.de> for the bug report.
728 Normally, the device name and the current volume number
729 are passed on the command line of the script. However,
730 if you want the old style script (with no arguments
731 passed on the command line), you can enable it in
732 configure with the --enable-oldstylefscript.
734 2. Use posix signal handling to preserve dump functionality
735 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
738 3. Made the exit code of restore in case of a 'C'ompare
739 command reflect the result of the compare. An exit status
740 of 0 means the dump archive is correct, 1 means tape errors,
741 2 means that some files were modified. Thanks to Kenneth Porter
742 <shiva@well.com> for the suggestion.
744 4. Made (finally) quotes work in interactive restore.
746 5. Small fixes in order to allow dump to compile with a
747 really old e2fsprogs version. Thanks to Ian Zimmerman
748 <itz@speakeasy.org> for the bug report.
750 6. Add GNU readline capabilities to interactive restore.
751 Use configure's --enable-readline flag to enable this feature.
752 Thanks to Patrik Schindler <poc@pocnet.net> for the
755 7. Do the compare on the fly in restore 'C' mode (this will
756 allow not to exhaust the available /tmp space when
757 ccmparing large files). Thanks to Kenneth Porter
758 <shiva@well.com> for the suggestion.
760 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
761 ====================================================================
763 1. Fixed some several duplicate 'DUMP: DUMP:' in the
766 2. Corrected the estimation of blocks to dump. Note that
767 this is still wrong for large directory inodes, due
768 to the size of a BSD directory entry on the tape
769 (estimation is based on the size of the ext2 directory,
770 which is smaller because it doesn't contain the null
771 character at the end).
773 3. Made dump report the total number of MB written to
774 tape at the end of run. Thanks to W. Reilly Cooley
775 <wcooley@nakedape.cc> for the patch.
777 4. Added the -X option to restore giving the possibility
778 to read the names of the files to be extracted/listed
779 from a text file (in addition of the command line).
780 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
783 5. Added the device name and the current volume number
784 as arguments to the end of tape script (dump -F option).
786 6. Made the multi-volume dump work again (after having
787 broken it in 0.4b15).
789 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
790 ===================================================================
792 1. Added a prompt command in interactive restore mode. Thanks
793 to Andreas Dilger <adilger@home.com> for the patch.
795 2. Fixed a buffer overflow problem in dump (caused by
796 not checking the size of the filesystem parameter).
797 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
798 reporting this on Bugtraq (and to several dump users
799 who forwarded me his mail).
801 3. Added the '-F script' option to dump in order to
802 launch a script at the end of each tape (to be used
803 with a tape changer, or to notify the sysadmin by
806 4. Fixed a bug in restore compare code caused by the changes
809 5. Fixed the treatment of options using the old BSD syntax
810 in both dump and restore.
812 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
813 =======================================================================
815 1. Fixed a bug in dump which may have caused invalid deleted
816 directories to be dumped out if they were deleted after the
817 mapping pass. This could occure on active filesystem and lead
818 to heap corruption (causing dump malfunction in many possible ways).
819 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
820 bug and submitting the patch.
822 2. Fixed the handling of the filesystem parameter in dump. A
823 '/mnt/disk' parameter caused the disk contents to be dumped,
824 but a '/mnt/disk/' parameter caused the mountpoint directory
825 to be dumped (generally an empty directory).
827 3. Improved the output of dump in order to tell which directory
828 it is currently dumping (when dumping a subtree).
830 4. Added the '-e' exclude inode option to dump. Thanks to
831 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
833 5. Added a REPORTING-BUGS file in order to provide a guide
834 on how to correctly report a bug in dump/restore.
836 6. Fixed a restore problem when restoring a hard link to an inode
837 having the immutable or append-only attribute set. Thanks to
838 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
840 7. Fixed a compatibility problem between dumps made on little
841 endian machines (the format was correct) and big endian
842 machines (the format was incorrect). This fix break the
843 compatibility with the older dumps made on big endian
844 machines (sparc, m86k, ppc etc). For the first time in
845 linux dump's history (I believe), the dumps made by *BSD,
846 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
847 so interchangeable. Thanks to Rob Cermak
848 <cermak@ahab.rutgers.edu> for submitting the bug and
849 helping me test the fix.
851 8. Fixed the way dump reports the remaining percent/time, if
852 the number of blocks actually dumped exceeds the estimated
853 number of blocks. Thanks to Jean-Paul van der Jagt
854 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
856 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
857 ======================================================================
859 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
860 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
862 2. Removed the requirement to build the RPM as root from the
863 spec file. Thanks to Christian Weisgerber
864 <naddy@mips.rhein-neckar.de> for submitting this.
866 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
867 causing dump to block when dumping really huge filesystems.
868 Many thanks to Patrik Schindler <poc@pocnet.net> for
869 helping me find this bug.
871 4. Fixed the treatment for an interrupt signal when dump access
872 the remote tape through RSH. Thanks to Christian Weisgerber
873 <naddy@mips.rhein-neckar.de> for providing the patch.
875 5. Fixed a bug which was causing dump/restore to display
876 garbage characters instead of the remote host name.
878 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
879 =====================================================================
881 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
882 <kukuk@suse.de> for submitting the patch.
884 2. Fix for the exit code when using the size estimate option of
885 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
886 submitting the patch.
888 3. Handle EINTR in atomical reads/writes in dump, which was causing
889 dump to fail on some systems. Thanks to Eric Jergensen
890 <eric@dvns.com> for reporting the bug and submitting the patch.
892 4. Handle more than 16 characters for the device names in dumpdates.
893 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
894 tracking down the problem and proposing the solution.
896 5. Fixed a bug in dump which prevented the creation of the
897 dumpdates file when doing a 0-level dump without already
898 having a dumpdates file. Thanks to Patrik Schindler
899 <poc@pocnet.net> for reporting the bug.
901 6. Changed the way dump 'S' flag reports the size estimate
902 from number of blocks into bytes (making it compatible
903 with the Solaris version, and simplifying things for
904 amanda users). Thanks to Jason L Tibbitts III
905 <tibbs@math.uh.edu> for reporting the bug.
907 7. Fixed a compatibility problem in linux/alpha dump tape format.
908 Now the linux/alpha dump are (again) compatible with the
909 other dump formats. But this breaks compatibility with
910 older dumps made on alpha. Thanks to Mike Tibor
911 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
913 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
914 ======================================================================
916 1. Added a '--enable-kerberos' to configure.
918 2. Added a 'S' option to dump which determines the amount of space
919 that is needed to perform the dump without actually doing it, similar
920 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
921 <cermak@ahab.rutgers.edu>.
923 3. Added a 'M' multi-volume option to dump and restore which enables
924 dumping to multiple files (useful when dumping to an ext2
925 partition to make several dump files in order to bypass the 2GB
926 file size limitation). The 'f' argument is treated as a prefix and
927 the output files will be named <prefix>001, <prefix>002 etc. With
928 the 'M' flag, restore automatically selects the right file without
929 asking to enter a new tape each time.
931 4. Fixed a memory leak which was causing dump to grow very big
932 (270MB when dumping a 10GB filesystem...). Thanks to Jason
933 Fearon <jasonf@netrider.org.au> for reporting the bug.
935 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
936 ======================================================================
938 1. Make configure test if the system glob routines support
939 extended syntax (ALTDIRFUNC). If not, use the internal glob
940 routines instead of system ones. Thanks to Bernhard Sadlowski
941 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
942 and helping me resolve this and other minor libc5 compiling
945 2. Fix a problem when dumping a ext2fs with the 'filetype'
946 feature enabled. Thanks to Patrick J. LoPresti
947 <patl@cag.lcs.mit.edu> for reporting the bug and to
948 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
950 3. Made the nodump flag work on directories. A directory which
951 has the nodump flag gets never dumped, regardless of its
954 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
955 which allows dump on an active ext3 filesystem. However, this
956 is a "quick and dirty" patch which enables backup of an ext3
957 filesystem through the ext2 compatibility (by ignoring the
958 NEEDS_RECOVERY bit). The journal file is not recognized and
959 it is dumped (it should not).
961 5. Test the superblock compatibility flags when dumping, in order
962 to be sure that we know how to deal with specific features.
964 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
965 ====================================================================
967 1. Use lchown instead of chown, fixing a possible security problem
968 when restoring symlinks (a malicious user could use this
969 to deliberately corrupt the ownership of important system files).
970 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
971 this and providing the patch.
973 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
974 ====================================================================
976 1. Put dump sources under CVS, added Id tags in all files so
977 one can use 'ident' on binary files.
979 2. Added the dump/restore version in the usage text so one can
980 easily verify the version he is using.
982 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
983 a va_start/va_end problem on linux-ppc (always call va_start
984 va_end in pairs each time we use a vararg function).
986 4. Added again the DT_* constants because old libc does not
987 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
988 for submitting the bug report.
990 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
991 this should enable dumping big (huge) filesystems.
993 6. Added the RSH environment variable in order to be able to
994 use a rsh replacement like ssh when doing remote backups (and
995 bypass the security limitations of rcmd). Now you can do remote
996 backups without being root (or making dump setuid root).
998 7. Modified again the way dumpdates works. For incremental dumps,
999 we need to read dumpdates even if we are not using 'u' option.
1000 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1003 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1004 ===================================================================
1006 1. Removed the 'k' flag from the restore 'about' text if kerberos
1007 was not compiled in.
1009 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1010 to them (fsetflags takes a char*, setflags an open fd!).
1012 3. (f)setflags is called only if the flags aren't empty. If the
1013 file is a special file, a warning is printed, because changing
1014 flags implies opening the device. Normally, a special file
1015 should not have any flag... (Debian bug #29775, patch provided
1016 by Abhijit Dasgupta <abhijit@ans.net>).
1018 4. Made possible to dump a file system not mentioned in /etc/fstab.
1019 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1021 5. Changed the default behaviour to not create dumpdates
1022 unless 'u' option is specified. Removed the old "debian-patch"
1023 which provided the same thing. (Debian bug #38136, #33818).
1025 6. Removed all those dump*announce, since they were getting old...
1027 7. Added warning messages if dumpdates does not exist and
1028 when an inferior level dump does not exist (except for a level 0
1031 8. Debugged the glob calls in interactive mode: restore used a
1032 dirent struct which was different from the /usr/include/dirent.h
1033 one (this used to work, is it a glibc2 change?), so none of the
1034 compat glob (which used /usr/include/dirent.h) or the system glob
1035 worked. Restore use now the system dirent (and the system
1036 DT_* constants), which are compatible with BSD ones.
1038 9. Added a configure flag (--with-dumpdatespath) to specify
1039 the location of dumpdates file. By default, it is
1042 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1043 included the current date/version in man pages.
1045 11. Corrected the estimation of remaining time when
1046 the operator doesn't change the tapes quickly enough. This
1047 was an old bug, I thought I corrected it, and discovered
1048 that in fact it was corrected in two different places, so
1049 the results canceled each other...
1051 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1052 ===================================================================
1054 1. Integrated multiple patches from RedHat, Debian and SuSE:
1056 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1058 - several fixes in the man pages.
1059 - update the default tape device to /dev/st0.
1060 - many updates for Linux Alpha (byte ordering, size_t etc).
1062 - use environment variable for TMPDIR (instead of /tmp).
1063 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1064 - workaround egcs bug (RedHat bugs #4281 and #2989).
1065 - wire $(OPT) throughout Makefile's.
1067 2. Upgrade the dump revision to 1, making possible to dump filesystems
1068 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1070 3. Fix some compile warnings, prototype all functions.
1072 4. Use glibc err/glob instead of internal compatibility
1073 routines (only if available).
1075 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1076 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1078 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1079 ======================================================================
1081 1. Integrated the changes from FreeBSD-3.1-RELEASE
1082 (mostly bug fixes, buffer overruns, dump has now an "automatic
1083 tape length calculation" flag, dump/restore can use kerberos now
1084 (this is NOT tested), use environment variables for TAPE and
1087 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1089 3. Corrected a bug in restore when using 'C' option with multi-volumes
1090 tapes (files splited accros two tapes give "size changed" errors
1093 4. Corrected the long standing bug when dumping multiple tapes.
1094 This works for me, needs further testing.
1096 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1097 ====================================================================
1099 1. Dump now runs correctly on kernels 2.1.x
1100 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1102 Changes between versions 0.4b2 and 0.4b3
1103 ========================================
1105 1. Use realpath() if available
1107 2. Report statistics
1109 Changes between versions 0.4b1 and 0.4b2
1110 ========================================
1112 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1115 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1117 3. Fixed configure.in to correctly handle --enable-rmt
1119 Changes between versions 0.3 and 0.4b1
1120 ======================================
1122 1. Integrated the changes from 4.4BSD-Lite2
1124 2. Integrated the patches from Debian and Red Hat
1126 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1128 4. Changed dump to use the Ext2fs library to get block addresses. This
1129 should solve the endianness problem on SparcLinux.
1131 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1132 distribution's one) to use autoconf
1134 6. Fixed a few minor bugs
1136 Changes between versions 0.2e and 0.2f
1137 ======================================
1139 1. Added the creation of named pipes (fifos) in restore.
1141 2. Added the -N flag in the restore manual page.
1143 3. Added the file kernel.patch which contains the llseek() optimization
1144 patch for 1.2.x kernels.
1146 4. Fixed a bug in the restoration of symbolic links: owner and group were
1149 5. Integrated some changes from FreeBSD 2.2.
1151 6. Added a call to ftruncate() after restoring each file to restore
1152 correctly files ending by a hole.
1154 Changes between versions 0.2d and 0.2e
1155 ======================================
1157 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1158 with owner = root (0) and group = root/wheel/whatever (0).
1160 Changes between versions 0.2c and 0.2d
1161 ======================================
1163 1. Dump is now able to backup 2GB+ filesystems.
1165 2. Dump and restore can now be linked as static binaries.
1167 Changes between versions 0.2b and 0.2c
1168 ======================================
1170 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1172 Changes between versions 0.2a and 0.2b
1173 ======================================
1175 1. Really fixed the bug that I should have corrected in 0.2a.
1177 2. Enabled optimization again.
1179 Changes between versions 0.2 and 0.2a
1180 =====================================
1182 1. Disabled the optimization during compilation.
1184 Changes between versions 0.1 and 0.2
1185 ====================================
1187 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1188 the fs_type field (actually, I modified the file fstab.c to make it
1189 use the mntent functions).
1191 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1192 made by dump should be readable by the BSD restore and backups made
1193 by the BSD dump should be readable by restore. Unfortunately, this
1194 means that the dump format has changed between version 0.1 and version
1197 3. Dump is now able to backup a subtree, it is no longer limited to whole
1198 filesystems like the BSD version.
1200 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1203 Changes between versions 0.0 and 0.1
1204 ====================================
1206 1. Now create links rdump and rrestore during the `make install' step.
1208 2. Linux port specific bugs added to the manual pages
1210 3. Incorrect estimation of the number of tapes blocks fixed when doing
1211 incremental backups.
1213 4. Better ls-like format in restore in interactive mode.
