3 Changes between versions 0.4b31 and 0.4b32 (released ?????????????)
4 ===================================================================
6 1. Changed dump to use fcntl(F_SETLK) style locking instead
7 of flock() when locking the dumpdates file. With the old
8 locking scheme, a local user having read rights on the
9 dumpdates file could be able to do a Denial of Service attack
10 on dump. In order to lock the dumpdates file with the new
11 scheme, the user would need to have write access on the file.
12 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
13 reporting the bug (originally a bugtraq post).
15 2. Fixed interactive 'ls' which caused spurious errors warnings
16 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
17 <jorgen_ostling@users.sourceforge.net> for reporting this
20 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
21 ===================================================================
23 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
24 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
25 <eros@lamel.bo.cnr.it> for reporting the bug.
27 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
28 ===================================================================
30 1. Made dump print out the ext2 logical block number in case of a read
31 error, which can be given as an argument to debugfs' ncheck command,
32 in order to find out the affected inode. Added note about this
33 usage in dump's man page.
35 2. Fixed a problem in restore when reading tapes written on big
36 endian machines with very old versions of dump. The patch was
37 contributed by George Helffrich <george@geology.bristol.ac.uk>.
39 3. Fixed the tape length calculation when using large tapes
40 and compression. Thanks to Georg Lippold
41 <g_lippold@sourceforge.net> for reporting the bug.
43 4. Added a new set of examples in dump_on_cd_2 directory, based
44 on dump_on_cd examples but somewhat enhanced, supporting DVD
45 media, and localized in english and german. Thanks to
46 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
48 5. Made dump save 32 bit UID/GID. Internally, this was achieved
49 by switching from the old BSD inode format to the new BSD
50 inode format, which means that the tape format was changed.
51 However, since all restore versions out there should
52 transparently support both inode formats, the change should
53 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
56 6. Fixed a lot of warnings in the code shown when compiling
57 with 'gcc -W'. Thanks to Matthias Andree
58 <matthias.andree@stud.uni-dortmund.de> for reporting this.
60 7. Fixed a small markup bug in the dump man page. Thanks to
61 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
64 8. Rewrote entirely the man pages using the tmac.an macro
65 package (Linux man page format) instead of the original BSD
66 format. They should be now cleaner and easier to modify.
68 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
69 ==================================================================
71 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
72 non Linux clients were misinterpreted. The description of the problem
73 (incompatible numbering in Linux mtio opcodes) is documented at
74 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
75 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
76 providing an excellent, cross-platform replacement for rmt in his
79 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
80 which caused restore to fail when the inode maps were not entirely
81 contained on the first volume (when using really small volumes or
82 when dumping a huge number of inodes).
84 3. Fixed a problem in dump, where files in subdirectories of directories
85 that have the nodump flag set (or being excluded with -e/-E) were
86 sometimes incorrectly dumped (instead of being excluded). The original
87 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
88 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
89 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
90 help testing the patch.
92 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
93 which makes one able to pipe the output of dump, by the net, to
94 a remote CD-burner server.
96 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
97 and use GNU's symbolic syntax over rmt instead of numerical values
98 to assure multiple platform compatibility.
100 6. Documented the -d option in restore.
102 7. Added a -v (verbose) mode to dump. For now it just prints the number
103 of the inode being dumped, but this could evolve in future versions
104 to include interesting debugging output.
106 8. Added a -o flag to restore, which automatically restores the current
107 directory permissions in -i or -x mode, without asking the operator
108 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
109 and Peter Samuel <peters@e-smith.com>.
111 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
112 ====================================================================
114 1. Fixed a bug in the QFA feature which could have caused
115 a bad tape positionning on restore (causing extra delays in
116 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
118 2. Added a small note in the dump man page specifying that
119 there should be no white space between the option letter and
120 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
122 3. Made restore work with older versions of the readline library,
123 by checking in configure for several extended symbols. Restore
124 can now be compiled with a readline as old as the 2.0 release
125 (though it may be a good idea to upgrade it to a more recent
126 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
127 reporting the build failures.
129 4. Fixed a performance problem with the QFA file creation in
130 dump, which made unnecessary seeks on the tape slowing down
131 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
132 reporting this issue.
134 5. Removed the inclusion of some kernel headers in the dump
135 source, which prevented the compile in some kernel/glibc
136 headers/architecture combination. Thanks to Bdale Garbee
137 <bdale@gag.com> for reporting the bug.
139 6. Added the appropriate error message when dump fails to
140 open the output file for writing. Thanks to Amith Varghese
141 <amithv@yahoo.com> for reporting this bug.
143 7. Made restore able to understand large Solaris ufsdump tapes
144 (containing inodes bigger than 4194304). Sun have introduced
145 an "extension" to the dump tape format when dealing with
146 those inodes, which was uncorrectly handled by Linux restore.
147 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
148 providing a test case.
150 8. Added the -m parameter to dump which optimises the output for
151 inodes having been changed but not modified since the last dump
152 ('changed' and 'modified' have the meaning defined in stat(2)).
153 For those inodes, dump will save only the metadata, instead of
154 saving the entire inode contents. Inodes which are either
155 directories or have been modified since the last dump are saved
156 in a regular way. Uses of this flag must be consistent, meaning
157 that either every dump in an incremental dump set have the flag,
160 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
161 =======================================================================
163 1. Fixed behaviour of dump when exceeding resource limits
166 2. Added the -L flag to restore to allow the user to specify a
167 maximal allowed number of miscompares when using restore
168 with the -C option to check the backup.
170 3. Detailed the manual entry for the -N option of restore.
172 4. Added the -a flag to restore to make able doing unattended
173 restores in -i or -x mode (automatically walks through the
174 multiple dump volumes).
176 5. Extended the QFA mode to work with local files and/or
177 remote tapes and files. This way, restore can know in advance
178 the tape number and the offset for the inodes to extract and
179 can minimize the extraction time by seeking directly to the
182 6. Added the -A <archive> option to both dump and restore,
183 which makes dump to archive a dump table-of-contents in
184 the specified file to be used by restore to determine
185 whether a file is in the dump file that is being restored.
186 (the archive file syntax is also compatible with the
187 Solaris ufsdump generated one).
189 7. Small fix in restore making it able to read some (broken ?)
190 Solaris ufsdump tapes.
192 8. Fixed dump to correctly recognise the root filesystem when using
193 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
194 for reporting this bug.
196 9. Added the -P <file> option to restore to create a
197 Quick File Access file from an already made dump. Patch
198 contributed by Uwe Gohlke <uwe@ugsoft.de>.
200 10. Made restore compile and run on Solaris, making it a
201 possible replacement for the standard ufsrestore. Port was
202 contributed by Uwe Gohlke <uwe@ugsoft.de>.
204 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
205 =====================================================================
207 1. Added a set of backup scripts from Eugenio Diaz
208 <getnito@yahoo.com> in the examples section. It features
209 automatic (cron based) full and incremental dumping of
210 several filesystems on a separate filesystem.
212 2. Fixed a off-by-one miscalculation which disabled dumping
213 a one letter subdirectory. Thanks to Chris Siebenmann
214 <cks@utcc.utoronto.ca> for reporting the bug.
216 3. Fixed several restore bugs occuring when trying to
217 restore some missing files on the tape. Thanks to Chris
218 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
220 4. Fixed --with-ldopts configure argument passing, installing from
221 a separate object directory, makefile cleanups contributed
222 by <splite@purdue.edu>.
224 5. Fix a bug which could caused, in some conditions, the highest
225 number inode of a filesystem, to not be dumped. Many thanks
226 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
229 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
230 =======================================================================
232 1. Added a mini howto from Patrick Walsh in the examples
235 2. Minor man pages syntax corrections. Thanks to
236 Chris Danis <screechco@home.com> for reporting the bugs.
238 3. Added a script from David B. Peterson <dave@toppledwagon.com>
239 to the examples section. It features dumping several
240 filesystems to a remote tape drive upon ssh.
242 4. Added a patch provided by Richard Jones <rich@annexia.org>
243 which allows BRADEMAX (number of read errors tolerated by
244 dump) to be adjusted using the -I option.
246 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
247 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
250 6. Add the -l option to restore to specify if, when doing a
251 remote restore, the file used to access the backup is a
252 regular file (the defaults being a tape drive). Restore needs
253 to know this information when reading a remote compressed
254 dump. Previously, this information was autodetected, but
255 the autodetection code fails (with ioctl: Inappropriate ioctl
256 for device) when using a non Linux remote box. Thanks to
257 many users and especially to Eros Albertazzi
258 <eros@lamel.bo.cnr.it> for reporting this.
260 7. Found a workaroung for the dump deadlock problem (3 childs
261 stuck in pause(), father in read()). The workaround seems
262 to work for me and several beta-testers. If it doesn't work
263 for you, please report back.
265 8. Updated the RPM spec file (BuildPrereq, URL etc).
267 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
268 ========================================================================
270 1. Fixed the permissions of a newly created QFA file by dump.
272 2. Cleaned up the source of dump (the external variables
273 definition was a complete mess, making possible to have
276 3. Fixed restore to use the full tape volume path when doing
277 a compare (since it changes the working directory to the
278 filesystem being compared in the process).
280 4. Added the -q option to dump which makes dump abort
281 whenever it needs operator attention. It should be
282 easier to use dump in scripts with this option.
284 5. Detect the use of incompatible options to dump and
285 refuse them (like -a and -B options together).
287 6. Added bzip2 compression to dump/restore (use option -j level
288 to select it). Note that you will need a restore version
289 >= 0.4b24 in order to restore a bzip2 compressed dump.
290 The same warning as for the zlib compression applies:
291 the tape format of a bzip2 dump is not compatible with the
292 original BSD tape format.
294 7. Fixed a overflow problem in dump corrupting the dump when
295 very large files were encountered. Thanks to Vladimir Nadvornik
298 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
299 kernel buffer/page cache before starting the dump, helping
300 a bit those who use dump on mounted filesystems. Thanks to
301 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
304 9. Updated the RPM spec file following the RedHat changes
305 (dynamically linked binaries now in /usr/sbin etc).
307 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
308 which enables restore to recognise multi volume compressed dumps
309 done on CD. Included his scripts for dump (which pipe the dump
310 output directly into cdrecord) and restore. There is now
311 possible to to backups to CD on the fly!
313 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
314 ===================================================================
316 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
317 Marcus Meissner (Caldera International Security Dept.).
319 2. Implement the Sun rmt extended protocol. Patch submitted
320 by Ian Gordon <iangordon@users.sourceforge.net>.
322 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
323 the linux kernel header. This ensures that dump always has the
324 latest version of this file. Patch submitted by
325 Andreas Dilger <adilger@turbolinux.com>.
327 4. Report any filesystem present in either /etc/fstab with a
328 positive passno or /etc/dumpdates in dump -w output.
329 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
331 5. Fixed the looping problem in dump introduced in the
334 6. Changed the -B option of dump to limit the size of
335 _compressed_ output per volume if compression is on.
336 Patch contributed by Helmut Jarausch
337 <jarausch@igpm.rwth-aachen.de>. Note however that, since
338 it is impossible to predict the size of the compressed
339 data before doing the compression, the -B limit is a bit
342 7. Fixed a bug in reading the operator typed file/tape path for
343 the next volume in restore.
345 8. Implemented a "-F script" option to restore which permits the
346 user to specify a script which will be launched at the
347 beginning of each tape, useful for automatic programming of
348 tape changers for example. See the restore man page for the
349 script parameters and return codes.
351 9. Small fix for the QFA routines provided by Uwe Gohlke
352 <uwe@ugsoft.de>, and some recommendations for QFA uses in
355 10. Fixed the multivolume restoring where making a mistake
356 to the 'Mount next tape' prompt caused several blocks to
359 11. Enhanced the -e option of dump to take as a parameter a
360 comma separated list of inode numbers.
362 12. Added the -E option to dump which specify a file containing
363 inode numbers to exclude from the dump.
365 13. Fixed the compressed multi-volume dump + restore.
367 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
368 ==================================================================
370 1. Made dump report the number of blocks dumped per volume.
371 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
373 2. Fix a bug in dump where waiting too much at the 'change volumes'
374 question caused the volume to be rewritten. Thanks to
375 Graham Reed <greed@users.sourceforge.net> for reporting the
376 bug and providing a patch.
378 3. Added a compression option to dump, contributed by Jerry
379 Peters <gapeters@worldnet.att.net>.
381 WARNING: the compression works only on files/pipes and
382 drives supporting variable block size.
384 WARNING2: tapes created using the compression feature are
385 incompatible with the standard dump tape format, and a
386 version of restore >= 0.4b22 will be needed for extraction.
388 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
389 architectures. Thanks to Paul Slootman <paul@debian.org> for
390 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
393 5. Many cleanups (CPP defines, const char warnings, check of
394 ext2fs COMPAT flags, time_t cleanups, added libext2 version
395 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
397 6. Made --prefix option work in configure. All the install path
398 are now based on the configure parameters.
400 7. Added the Quick File Access mode in dump/restore, contributed
401 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
402 a file tape position for each inode, and this file is used by
403 restore (if called with parameter Q and the filename)
404 to directly position the tape at the file restore is currently
405 working on. This saves hours when restoring single files from
406 large backups, saves the tapes and the drive's head. Use
407 --enable-qfa option of configure to compile in the QFA support.
409 8. Added the possibility to dump several files and directories
410 in a single invocation of dump. Thanks to Uwe Gohlke
411 <uwe@ugsoft.de> for implementing this option.
413 9. Fixed the dumping and restoring of files with holes
414 (files ending with holes didn't get dumped or restored
417 10. Fixed a socket descriptor leak in dump, which leaved opened
418 3 file descriptors per dump process (and there is one dump
421 11. Fixed dump large file system support, by explicit use of
422 open64/lseek64/etc functions (explicit use needed because
423 e2fsprogs libraries don't behave well when compiled with
424 FILE_OFFSET_BITS=64).
426 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
427 ======================================================================
429 1. Fixed some bugs in the dump -w|-W logic introduced by
430 the previous version. Thanks to Andreas Dilger
431 <adilger@turbolinux.com> for his help on this one.
433 2. Fixed again a compilation problem when using old e2fs
434 headers (filesystem label related). Thanks to many users
435 who reported this stupid error.
437 3. Fixed a build problem on old lib5 based systems dealing with
438 _PATH_MNTTAB being undefined. Thanks to John Adams
439 <johna@onevista.com> for reporting the bug.
441 4. Improved the error detection in restore when creating
442 the temporary files in TMPDIR. Now restore will corectly
443 report a 'no space left on device' error instead of
444 strange errors which could imply an archive corruption.
445 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
446 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
448 5. Added the throughput information in dump's progression
449 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
452 6. Use libext2fs's inode scanning routines, which are particularly
453 robust when dealing with errors (especially when having some
454 bad blocks on the filesystem). Many thanks to Colin
455 <colin@horizon.com> for reporting the bug, investigating
456 the issues, finding a workaround, writing the patch and
457 fully testing it... (of course, if this patch will break
458 anything, he is to blame for :-)).
460 7. Made dump and restore LFS aware. Dump can dump a filesystem
461 containing large files, generate a large file on output and
462 restore can restore them. This feature is not enabled by
463 default, use --enable-largefile option of configure to enable
464 it (you need to have a LFS aware glibc though). Thanks to
465 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
466 and to Theodore T'so <tytso@valinux.com> for his always
469 8. Made dump ask upon a tape write error if it should rewrite
470 the current volume (assume this is a bad tape) or if it should
471 assume an end-of-tape condition (useful for tape drives which
472 behaves badly at the end of the tape). Thanks to Andreas
473 Dilger <adilger@turbolinux.com> for the suggestion.
475 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
476 =======================================================================
478 1. Fixed a small compilation problem due to a change
479 in the definintion of the struct sigaction in
480 glibc 2.0 / libc5. Thanks to Gunther Schlegel
481 <schlegel@riege.de> for reporting the bug and to
482 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
485 2. Modified the label and uuid analysis in order to be
486 self-contained (independant of kernel/libc headers). This
487 should fix the compile with older kernel/libc headers and
488 will preserve the functionality. Thanks to Bernhard Erdmann
489 <bernhard.erdmann@gmx.de> for reporting the bug.
491 3. The 'exclude inode' option, if applied to a directory
492 inode, excludes now correctly all the leaves of this
493 directory. Thanks to John R. Dennison
494 <gerdesas@users.sourceforge.net> for reporting the bug.
496 4. Fixed the '-e' option to disable the possibility
497 to exclude the root inode (which causes the dumps to
498 be unreadable by restore). Prevented array overflow
499 when multiple -e options are used.
501 5. Fixed dump to correctly interpret a filesystem argument
502 which is a mountpoint and it is not an absolute path
503 (as specified in the fstab). Thanks to Bernhard R. Erdmann
504 <be@berdmann.de> for reporting the bug.
506 6. Made dump able to backup files larger than 2 GB. Note that
507 dump still doesn't cope with files larger than 4 GB.
509 7. Restore the real uid and gid before invoking an external
510 RSH program (big hole when dump or restore is suid root!).
512 8. Get the values for the default tape device and the location
513 of fstab file from the system headers. Thanks to
514 Andreas Dilger <adilger@turbolinux.com> for the patch.
516 9. Made dump -w|-W report all recognized filesystems
517 present in either /etc/fstab or /etc/dumpdates, and present
518 the list in the same order as in fstab file. Thanks
519 to Andreas Dilger <adilger@turbolinux.com> for the patch.
521 10. Made dump's -a (automatic end of tape detection) the
522 default. Specifying one of -B, -c, -d or -s options will
523 override the EOM detection. Thanks to Andreas Dilger
524 <adilger@turbolinux.com> for the patch.
526 11. Save the ext2 filesystem label into the dump volume label.
527 Specifying a volume label on the command line (-L option)
528 will override this feature. Thanks to Andreas Dilger
529 <adilger@turbolinux.com> for the patch.
531 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
532 =====================================================================
534 1. Fixed the signal handling in dump (which I broke in 0.4b17)
535 which was causing several strange dump failures (dump
536 hanged or segmentation faults etc).
538 2. Specified the default blocksize in the dump man page.
540 3. Changed two info messages of restore to be written on stdout
541 instead of stderr in order to leave stderr only for errors
542 or warnings. Thanks to Stephen Atwell
543 <satwell@urbana.css.mot.com> for the suggestion.
545 4. Corrected an off by one calculation which prevented
546 dumping a directory having a 1 character name length.
547 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
548 for reporting the bug.
550 5. Reinforce dump in order to allow only level 0 and no
551 -u option when dumping a subdirectory, and document
552 this in the man page. Thanks to Bernhard Erdmann
553 <bernhard.erdmann@gmx.de> for reporting the bug.
555 6. Fixed a small harmless bug in restore which caused
556 in some conditions hard links to be restored several
557 times (therefore generation some warning messages).
558 Thanks to Kenneth Porter <shiva@well.com> for
561 7. Updated the RPM spec file to the latest RedHat version,
562 providing FHS packaging and other cosmetic changes.
563 You will need RPM version >= 3.0.5 in order to build the RPM.
565 8. Updated the configure script to check for libtermcap
566 before checking for libreadline, because we need this
567 library in order to compile the readline support.
569 9. Made dump understand the LABEL= and UUID= notation
570 both in /etc/fstab and on the command line. Note that
571 you will need the /proc filesystem in order to use
572 these notations. Thanks to Erik Troan <ewt@redhat.com>
573 for providing the patch.
575 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
576 ===================================================================
578 1. Fixed a potential buffer overflow in restore. Thanks
579 to Stan Bubrouski <satan@fastdial.net> for reporting
582 2. Fixed a readline-related bug which prevented
583 'cat DUMPFILE | restore -i -f -' from working. Thanks
584 to Charles Karney <karney@users.sourceforge.net>
587 3. Changed a few "panic" into "exit", causing restore to
588 be more stable against some attacks (like the last one
589 reported on Bugtraq, although the last version of restore
590 was not vulnerable - just dumped core). Thanks to
591 Andreas Hasenack <andreas@conectiva.com.br> for reporting
594 4. Removed the suid-root bit on dump and restore in the
595 default build (and generated RPMs). It should be safer
596 now. Users who need the suid-root capabilities in order
597 to make network backups should read first the man page
598 of dump and enable the suid bit manually.
600 5. Added -ltermcap to the compile parameters for restore
601 when using readline support, in order to make the compile
602 process work on some systems (SuSE ?). Thanks to
603 Patrik Schindler <poc@pocnet.net> for reporting the bug.
605 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
606 ====================================================================
608 1. The -F script is called now *only* at the end of a tape,
609 not at the end of the dump. Thanks to Christian Haul
610 <haul@informatik.tu-darmstadt.de> for the bug report.
612 Normally, the device name and the current volume number
613 are passed on the command line of the script. However,
614 if you want the old style script (with no arguments
615 passed on the command line), you can enable it in
616 configure with the --enable-oldstylefscript.
618 2. Use posix signal handling to preserve dump functionality
619 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
622 3. Made the exit code of restore in case of a 'C'ompare
623 command reflect the result of the compare. An exit status
624 of 0 means the dump archive is correct, 1 means tape errors,
625 2 means that some files were modified. Thanks to Kenneth Porter
626 <shiva@well.com> for the suggestion.
628 4. Made (finally) quotes work in interactive restore.
630 5. Small fixes in order to allow dump to compile with a
631 really old e2fsprogs version. Thanks to Ian Zimmerman
632 <itz@speakeasy.org> for the bug report.
634 6. Add GNU readline capabilities to interactive restore.
635 Use configure's --enable-readline flag to enable this feature.
636 Thanks to Patrik Schindler <poc@pocnet.net> for the
639 7. Do the compare on the fly in restore 'C' mode (this will
640 allow not to exhaust the available /tmp space when
641 ccmparing large files). Thanks to Kenneth Porter
642 <shiva@well.com> for the suggestion.
644 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
645 ====================================================================
647 1. Fixed some several duplicate 'DUMP: DUMP:' in the
650 2. Corrected the estimation of blocks to dump. Note that
651 this is still wrong for large directory inodes, due
652 to the size of a BSD directory entry on the tape
653 (estimation is based on the size of the ext2 directory,
654 which is smaller because it doesn't contain the null
655 character at the end).
657 3. Made dump report the total number of MB written to
658 tape at the end of run. Thanks to W. Reilly Cooley
659 <wcooley@nakedape.cc> for the patch.
661 4. Added the -X option to restore giving the possibility
662 to read the names of the files to be extracted/listed
663 from a text file (in addition of the command line).
664 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
667 5. Added the device name and the current volume number
668 as arguments to the end of tape script (dump -F option).
670 6. Made the multi-volume dump work again (after having
671 broken it in 0.4b15).
673 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
674 ===================================================================
676 1. Added a prompt command in interactive restore mode. Thanks
677 to Andreas Dilger <adilger@home.com> for the patch.
679 2. Fixed a buffer overflow problem in dump (caused by
680 not checking the size of the filesystem parameter).
681 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
682 reporting this on Bugtraq (and to several dump users
683 who forwarded me his mail).
685 3. Added the '-F script' option to dump in order to
686 launch a script at the end of each tape (to be used
687 with a tape changer, or to notify the sysadmin by
690 4. Fixed a bug in restore compare code caused by the changes
693 5. Fixed the treatment of options using the old BSD syntax
694 in both dump and restore.
696 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
697 =======================================================================
699 1. Fixed a bug in dump which may have caused invalid deleted
700 directories to be dumped out if they were deleted after the
701 mapping pass. This could occure on active filesystem and lead
702 to heap corruption (causing dump malfunction in many possible ways).
703 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
704 bug and submitting the patch.
706 2. Fixed the handling of the filesystem parameter in dump. A
707 '/mnt/disk' parameter caused the disk contents to be dumped,
708 but a '/mnt/disk/' parameter caused the mountpoint directory
709 to be dumped (generally an empty directory).
711 3. Improved the output of dump in order to tell which directory
712 it is currently dumping (when dumping a subtree).
714 4. Added the '-e' exclude inode option to dump. Thanks to
715 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
717 5. Added a REPORTING-BUGS file in order to provide a guide
718 on how to correctly report a bug in dump/restore.
720 6. Fixed a restore problem when restoring a hard link to an inode
721 having the immutable or append-only attribute set. Thanks to
722 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
724 7. Fixed a compatibility problem between dumps made on little
725 endian machines (the format was correct) and big endian
726 machines (the format was incorrect). This fix break the
727 compatibility with the older dumps made on big endian
728 machines (sparc, m86k, ppc etc). For the first time in
729 linux dump's history (I believe), the dumps made by *BSD,
730 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
731 so interchangeable. Thanks to Rob Cermak
732 <cermak@ahab.rutgers.edu> for submitting the bug and
733 helping me test the fix.
735 8. Fixed the way dump reports the remaining percent/time, if
736 the number of blocks actually dumped exceeds the estimated
737 number of blocks. Thanks to Jean-Paul van der Jagt
738 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
740 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
741 ======================================================================
743 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
744 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
746 2. Removed the requirement to build the RPM as root from the
747 spec file. Thanks to Christian Weisgerber
748 <naddy@mips.rhein-neckar.de> for submitting this.
750 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
751 causing dump to block when dumping really huge filesystems.
752 Many thanks to Patrik Schindler <poc@pocnet.net> for
753 helping me find this bug.
755 4. Fixed the treatment for an interrupt signal when dump access
756 the remote tape through RSH. Thanks to Christian Weisgerber
757 <naddy@mips.rhein-neckar.de> for providing the patch.
759 5. Fixed a bug which was causing dump/restore to display
760 garbage characters instead of the remote host name.
762 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
763 =====================================================================
765 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
766 <kukuk@suse.de> for submitting the patch.
768 2. Fix for the exit code when using the size estimate option of
769 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
770 submitting the patch.
772 3. Handle EINTR in atomical reads/writes in dump, which was causing
773 dump to fail on some systems. Thanks to Eric Jergensen
774 <eric@dvns.com> for reporting the bug and submitting the patch.
776 4. Handle more than 16 characters for the device names in dumpdates.
777 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
778 tracking down the problem and proposing the solution.
780 5. Fixed a bug in dump which prevented the creation of the
781 dumpdates file when doing a 0-level dump without already
782 having a dumpdates file. Thanks to Patrik Schindler
783 <poc@pocnet.net> for reporting the bug.
785 6. Changed the way dump 'S' flag reports the size estimate
786 from number of blocks into bytes (making it compatible
787 with the Solaris version, and simplifying things for
788 amanda users). Thanks to Jason L Tibbitts III
789 <tibbs@math.uh.edu> for reporting the bug.
791 7. Fixed a compatibility problem in linux/alpha dump tape format.
792 Now the linux/alpha dump are (again) compatible with the
793 other dump formats. But this breaks compatibility with
794 older dumps made on alpha. Thanks to Mike Tibor
795 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
797 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
798 ======================================================================
800 1. Added a '--enable-kerberos' to configure.
802 2. Added a 'S' option to dump which determines the amount of space
803 that is needed to perform the dump without actually doing it, similar
804 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
805 <cermak@ahab.rutgers.edu>.
807 3. Added a 'M' multi-volume option to dump and restore which enables
808 dumping to multiple files (useful when dumping to an ext2
809 partition to make several dump files in order to bypass the 2GB
810 file size limitation). The 'f' argument is treated as a prefix and
811 the output files will be named <prefix>001, <prefix>002 etc. With
812 the 'M' flag, restore automatically selects the right file without
813 asking to enter a new tape each time.
815 4. Fixed a memory leak which was causing dump to grow very big
816 (270MB when dumping a 10GB filesystem...). Thanks to Jason
817 Fearon <jasonf@netrider.org.au> for reporting the bug.
819 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
820 ======================================================================
822 1. Make configure test if the system glob routines support
823 extended syntax (ALTDIRFUNC). If not, use the internal glob
824 routines instead of system ones. Thanks to Bernhard Sadlowski
825 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
826 and helping me resolve this and other minor libc5 compiling
829 2. Fix a problem when dumping a ext2fs with the 'filetype'
830 feature enabled. Thanks to Patrick J. LoPresti
831 <patl@cag.lcs.mit.edu> for reporting the bug and to
832 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
834 3. Made the nodump flag work on directories. A directory which
835 has the nodump flag gets never dumped, regardless of its
838 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
839 which allows dump on an active ext3 filesystem. However, this
840 is a "quick and dirty" patch which enables backup of an ext3
841 filesystem through the ext2 compatibility (by ignoring the
842 NEEDS_RECOVERY bit). The journal file is not recognized and
843 it is dumped (it should not).
845 5. Test the superblock compatibility flags when dumping, in order
846 to be sure that we know how to deal with specific features.
848 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
849 ====================================================================
851 1. Use lchown instead of chown, fixing a possible security problem
852 when restoring symlinks (a malicious user could use this
853 to deliberately corrupt the ownership of important system files).
854 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
855 this and providing the patch.
857 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
858 ====================================================================
860 1. Put dump sources under CVS, added Id tags in all files so
861 one can use 'ident' on binary files.
863 2. Added the dump/restore version in the usage text so one can
864 easily verify the version he is using.
866 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
867 a va_start/va_end problem on linux-ppc (always call va_start
868 va_end in pairs each time we use a vararg function).
870 4. Added again the DT_* constants because old libc does not
871 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
872 for submitting the bug report.
874 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
875 this should enable dumping big (huge) filesystems.
877 6. Added the RSH environment variable in order to be able to
878 use a rsh replacement like ssh when doing remote backups (and
879 bypass the security limitations of rcmd). Now you can do remote
880 backups without being root (or making dump setuid root).
882 7. Modified again the way dumpdates works. For incremental dumps,
883 we need to read dumpdates even if we are not using 'u' option.
884 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
887 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
888 ===================================================================
890 1. Removed the 'k' flag from the restore 'about' text if kerberos
893 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
894 to them (fsetflags takes a char*, setflags an open fd!).
896 3. (f)setflags is called only if the flags aren't empty. If the
897 file is a special file, a warning is printed, because changing
898 flags implies opening the device. Normally, a special file
899 should not have any flag... (Debian bug #29775, patch provided
900 by Abhijit Dasgupta <abhijit@ans.net>).
902 4. Made possible to dump a file system not mentioned in /etc/fstab.
903 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
905 5. Changed the default behaviour to not create dumpdates
906 unless 'u' option is specified. Removed the old "debian-patch"
907 which provided the same thing. (Debian bug #38136, #33818).
909 6. Removed all those dump*announce, since they were getting old...
911 7. Added warning messages if dumpdates does not exist and
912 when an inferior level dump does not exist (except for a level 0
915 8. Debugged the glob calls in interactive mode: restore used a
916 dirent struct which was different from the /usr/include/dirent.h
917 one (this used to work, is it a glibc2 change?), so none of the
918 compat glob (which used /usr/include/dirent.h) or the system glob
919 worked. Restore use now the system dirent (and the system
920 DT_* constants), which are compatible with BSD ones.
922 9. Added a configure flag (--with-dumpdatespath) to specify
923 the location of dumpdates file. By default, it is
926 10. Added the "AUTHOR" and "AVAILABILITY" sections and
927 included the current date/version in man pages.
929 11. Corrected the estimation of remaining time when
930 the operator doesn't change the tapes quickly enough. This
931 was an old bug, I thought I corrected it, and discovered
932 that in fact it was corrected in two different places, so
933 the results canceled each other...
935 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
936 ===================================================================
938 1. Integrated multiple patches from RedHat, Debian and SuSE:
940 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
942 - several fixes in the man pages.
943 - update the default tape device to /dev/st0.
944 - many updates for Linux Alpha (byte ordering, size_t etc).
946 - use environment variable for TMPDIR (instead of /tmp).
947 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
948 - workaround egcs bug (RedHat bugs #4281 and #2989).
949 - wire $(OPT) throughout Makefile's.
951 2. Upgrade the dump revision to 1, making possible to dump filesystems
952 made with e2fsprogs-1.15 or newer. Nothing seems to break...
954 3. Fix some compile warnings, prototype all functions.
956 4. Use glibc err/glob instead of internal compatibility
957 routines (only if available).
959 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
960 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
962 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
963 ======================================================================
965 1. Integrated the changes from FreeBSD-3.1-RELEASE
966 (mostly bug fixes, buffer overruns, dump has now an "automatic
967 tape length calculation" flag, dump/restore can use kerberos now
968 (this is NOT tested), use environment variables for TAPE and
971 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
973 3. Corrected a bug in restore when using 'C' option with multi-volumes
974 tapes (files splited accros two tapes give "size changed" errors
977 4. Corrected the long standing bug when dumping multiple tapes.
978 This works for me, needs further testing.
980 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
981 ====================================================================
983 1. Dump now runs correctly on kernels 2.1.x
984 Fix made by Gerald Peters <gapeters@worldnet.att.net>
986 Changes between versions 0.4b2 and 0.4b3
987 ========================================
989 1. Use realpath() if available
993 Changes between versions 0.4b1 and 0.4b2
994 ========================================
996 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
999 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1001 3. Fixed configure.in to correctly handle --enable-rmt
1003 Changes between versions 0.3 and 0.4b1
1004 ======================================
1006 1. Integrated the changes from 4.4BSD-Lite2
1008 2. Integrated the patches from Debian and Red Hat
1010 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1012 4. Changed dump to use the Ext2fs library to get block addresses. This
1013 should solve the endianness problem on SparcLinux.
1015 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1016 distribution's one) to use autoconf
1018 6. Fixed a few minor bugs
1020 Changes between versions 0.2e and 0.2f
1021 ======================================
1023 1. Added the creation of named pipes (fifos) in restore.
1025 2. Added the -N flag in the restore manual page.
1027 3. Added the file kernel.patch which contains the llseek() optimization
1028 patch for 1.2.x kernels.
1030 4. Fixed a bug in the restoration of symbolic links: owner and group were
1033 5. Integrated some changes from FreeBSD 2.2.
1035 6. Added a call to ftruncate() after restoring each file to restore
1036 correctly files ending by a hole.
1038 Changes between versions 0.2d and 0.2e
1039 ======================================
1041 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1042 with owner = root (0) and group = root/wheel/whatever (0).
1044 Changes between versions 0.2c and 0.2d
1045 ======================================
1047 1. Dump is now able to backup 2GB+ filesystems.
1049 2. Dump and restore can now be linked as static binaries.
1051 Changes between versions 0.2b and 0.2c
1052 ======================================
1054 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1056 Changes between versions 0.2a and 0.2b
1057 ======================================
1059 1. Really fixed the bug that I should have corrected in 0.2a.
1061 2. Enabled optimization again.
1063 Changes between versions 0.2 and 0.2a
1064 =====================================
1066 1. Disabled the optimization during compilation.
1068 Changes between versions 0.1 and 0.2
1069 ====================================
1071 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1072 the fs_type field (actually, I modified the file fstab.c to make it
1073 use the mntent functions).
1075 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1076 made by dump should be readable by the BSD restore and backups made
1077 by the BSD dump should be readable by restore. Unfortunately, this
1078 means that the dump format has changed between version 0.1 and version
1081 3. Dump is now able to backup a subtree, it is no longer limited to whole
1082 filesystems like the BSD version.
1084 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1087 Changes between versions 0.0 and 0.1
1088 ====================================
1090 1. Now create links rdump and rrestore during the `make install' step.
1092 2. Linux port specific bugs added to the manual pages
1094 3. Incorrect estimation of the number of tapes blocks fixed when doing
1095 incremental backups.
1097 4. Better ls-like format in restore in interactive mode.
