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 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
16 ===================================================================
18 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
19 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
20 <eros@lamel.bo.cnr.it> for reporting the bug.
22 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
23 ===================================================================
25 1. Made dump print out the ext2 logical block number in case of a read
26 error, which can be given as an argument to debugfs' ncheck command,
27 in order to find out the affected inode. Added note about this
28 usage in dump's man page.
30 2. Fixed a problem in restore when reading tapes written on big
31 endian machines with very old versions of dump. The patch was
32 contributed by George Helffrich <george@geology.bristol.ac.uk>.
34 3. Fixed the tape length calculation when using large tapes
35 and compression. Thanks to Georg Lippold
36 <g_lippold@sourceforge.net> for reporting the bug.
38 4. Added a new set of examples in dump_on_cd_2 directory, based
39 on dump_on_cd examples but somewhat enhanced, supporting DVD
40 media, and localized in english and german. Thanks to
41 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
43 5. Made dump save 32 bit UID/GID. Internally, this was achieved
44 by switching from the old BSD inode format to the new BSD
45 inode format, which means that the tape format was changed.
46 However, since all restore versions out there should
47 transparently support both inode formats, the change should
48 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
51 6. Fixed a lot of warnings in the code shown when compiling
52 with 'gcc -W'. Thanks to Matthias Andree
53 <matthias.andree@stud.uni-dortmund.de> for reporting this.
55 7. Fixed a small markup bug in the dump man page. Thanks to
56 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
59 8. Rewrote entirely the man pages using the tmac.an macro
60 package (Linux man page format) instead of the original BSD
61 format. They should be now cleaner and easier to modify.
63 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
64 ==================================================================
66 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
67 non Linux clients were misinterpreted. The description of the problem
68 (incompatible numbering in Linux mtio opcodes) is documented at
69 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
70 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
71 providing an excellent, cross-platform replacement for rmt in his
74 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
75 which caused restore to fail when the inode maps were not entirely
76 contained on the first volume (when using really small volumes or
77 when dumping a huge number of inodes).
79 3. Fixed a problem in dump, where files in subdirectories of directories
80 that have the nodump flag set (or being excluded with -e/-E) were
81 sometimes incorrectly dumped (instead of being excluded). The original
82 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
83 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
84 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
85 help testing the patch.
87 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
88 which makes one able to pipe the output of dump, by the net, to
89 a remote CD-burner server.
91 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
92 and use GNU's symbolic syntax over rmt instead of numerical values
93 to assure multiple platform compatibility.
95 6. Documented the -d option in restore.
97 7. Added a -v (verbose) mode to dump. For now it just prints the number
98 of the inode being dumped, but this could evolve in future versions
99 to include interesting debugging output.
101 8. Added a -o flag to restore, which automatically restores the current
102 directory permissions in -i or -x mode, without asking the operator
103 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
104 and Peter Samuel <peters@e-smith.com>.
106 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
107 ====================================================================
109 1. Fixed a bug in the QFA feature which could have caused
110 a bad tape positionning on restore (causing extra delays in
111 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
113 2. Added a small note in the dump man page specifying that
114 there should be no white space between the option letter and
115 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
117 3. Made restore work with older versions of the readline library,
118 by checking in configure for several extended symbols. Restore
119 can now be compiled with a readline as old as the 2.0 release
120 (though it may be a good idea to upgrade it to a more recent
121 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
122 reporting the build failures.
124 4. Fixed a performance problem with the QFA file creation in
125 dump, which made unnecessary seeks on the tape slowing down
126 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
127 reporting this issue.
129 5. Removed the inclusion of some kernel headers in the dump
130 source, which prevented the compile in some kernel/glibc
131 headers/architecture combination. Thanks to Bdale Garbee
132 <bdale@gag.com> for reporting the bug.
134 6. Added the appropriate error message when dump fails to
135 open the output file for writing. Thanks to Amith Varghese
136 <amithv@yahoo.com> for reporting this bug.
138 7. Made restore able to understand large Solaris ufsdump tapes
139 (containing inodes bigger than 4194304). Sun have introduced
140 an "extension" to the dump tape format when dealing with
141 those inodes, which was uncorrectly handled by Linux restore.
142 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
143 providing a test case.
145 8. Added the -m parameter to dump which optimises the output for
146 inodes having been changed but not modified since the last dump
147 ('changed' and 'modified' have the meaning defined in stat(2)).
148 For those inodes, dump will save only the metadata, instead of
149 saving the entire inode contents. Inodes which are either
150 directories or have been modified since the last dump are saved
151 in a regular way. Uses of this flag must be consistent, meaning
152 that either every dump in an incremental dump set have the flag,
155 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
156 =======================================================================
158 1. Fixed behaviour of dump when exceeding resource limits
161 2. Added the -L flag to restore to allow the user to specify a
162 maximal allowed number of miscompares when using restore
163 with the -C option to check the backup.
165 3. Detailed the manual entry for the -N option of restore.
167 4. Added the -a flag to restore to make able doing unattended
168 restores in -i or -x mode (automatically walks through the
169 multiple dump volumes).
171 5. Extended the QFA mode to work with local files and/or
172 remote tapes and files. This way, restore can know in advance
173 the tape number and the offset for the inodes to extract and
174 can minimize the extraction time by seeking directly to the
177 6. Added the -A <archive> option to both dump and restore,
178 which makes dump to archive a dump table-of-contents in
179 the specified file to be used by restore to determine
180 whether a file is in the dump file that is being restored.
181 (the archive file syntax is also compatible with the
182 Solaris ufsdump generated one).
184 7. Small fix in restore making it able to read some (broken ?)
185 Solaris ufsdump tapes.
187 8. Fixed dump to correctly recognise the root filesystem when using
188 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
189 for reporting this bug.
191 9. Added the -P <file> option to restore to create a
192 Quick File Access file from an already made dump. Patch
193 contributed by Uwe Gohlke <uwe@ugsoft.de>.
195 10. Made restore compile and run on Solaris, making it a
196 possible replacement for the standard ufsrestore. Port was
197 contributed by Uwe Gohlke <uwe@ugsoft.de>.
199 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
200 =====================================================================
202 1. Added a set of backup scripts from Eugenio Diaz
203 <getnito@yahoo.com> in the examples section. It features
204 automatic (cron based) full and incremental dumping of
205 several filesystems on a separate filesystem.
207 2. Fixed a off-by-one miscalculation which disabled dumping
208 a one letter subdirectory. Thanks to Chris Siebenmann
209 <cks@utcc.utoronto.ca> for reporting the bug.
211 3. Fixed several restore bugs occuring when trying to
212 restore some missing files on the tape. Thanks to Chris
213 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
215 4. Fixed --with-ldopts configure argument passing, installing from
216 a separate object directory, makefile cleanups contributed
217 by <splite@purdue.edu>.
219 5. Fix a bug which could caused, in some conditions, the highest
220 number inode of a filesystem, to not be dumped. Many thanks
221 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
224 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
225 =======================================================================
227 1. Added a mini howto from Patrick Walsh in the examples
230 2. Minor man pages syntax corrections. Thanks to
231 Chris Danis <screechco@home.com> for reporting the bugs.
233 3. Added a script from David B. Peterson <dave@toppledwagon.com>
234 to the examples section. It features dumping several
235 filesystems to a remote tape drive upon ssh.
237 4. Added a patch provided by Richard Jones <rich@annexia.org>
238 which allows BRADEMAX (number of read errors tolerated by
239 dump) to be adjusted using the -I option.
241 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
242 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
245 6. Add the -l option to restore to specify if, when doing a
246 remote restore, the file used to access the backup is a
247 regular file (the defaults being a tape drive). Restore needs
248 to know this information when reading a remote compressed
249 dump. Previously, this information was autodetected, but
250 the autodetection code fails (with ioctl: Inappropriate ioctl
251 for device) when using a non Linux remote box. Thanks to
252 many users and especially to Eros Albertazzi
253 <eros@lamel.bo.cnr.it> for reporting this.
255 7. Found a workaroung for the dump deadlock problem (3 childs
256 stuck in pause(), father in read()). The workaround seems
257 to work for me and several beta-testers. If it doesn't work
258 for you, please report back.
260 8. Updated the RPM spec file (BuildPrereq, URL etc).
262 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
263 ========================================================================
265 1. Fixed the permissions of a newly created QFA file by dump.
267 2. Cleaned up the source of dump (the external variables
268 definition was a complete mess, making possible to have
271 3. Fixed restore to use the full tape volume path when doing
272 a compare (since it changes the working directory to the
273 filesystem being compared in the process).
275 4. Added the -q option to dump which makes dump abort
276 whenever it needs operator attention. It should be
277 easier to use dump in scripts with this option.
279 5. Detect the use of incompatible options to dump and
280 refuse them (like -a and -B options together).
282 6. Added bzip2 compression to dump/restore (use option -j level
283 to select it). Note that you will need a restore version
284 >= 0.4b24 in order to restore a bzip2 compressed dump.
285 The same warning as for the zlib compression applies:
286 the tape format of a bzip2 dump is not compatible with the
287 original BSD tape format.
289 7. Fixed a overflow problem in dump corrupting the dump when
290 very large files were encountered. Thanks to Vladimir Nadvornik
293 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
294 kernel buffer/page cache before starting the dump, helping
295 a bit those who use dump on mounted filesystems. Thanks to
296 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
299 9. Updated the RPM spec file following the RedHat changes
300 (dynamically linked binaries now in /usr/sbin etc).
302 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
303 which enables restore to recognise multi volume compressed dumps
304 done on CD. Included his scripts for dump (which pipe the dump
305 output directly into cdrecord) and restore. There is now
306 possible to to backups to CD on the fly!
308 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
309 ===================================================================
311 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
312 Marcus Meissner (Caldera International Security Dept.).
314 2. Implement the Sun rmt extended protocol. Patch submitted
315 by Ian Gordon <iangordon@users.sourceforge.net>.
317 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
318 the linux kernel header. This ensures that dump always has the
319 latest version of this file. Patch submitted by
320 Andreas Dilger <adilger@turbolinux.com>.
322 4. Report any filesystem present in either /etc/fstab with a
323 positive passno or /etc/dumpdates in dump -w output.
324 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
326 5. Fixed the looping problem in dump introduced in the
329 6. Changed the -B option of dump to limit the size of
330 _compressed_ output per volume if compression is on.
331 Patch contributed by Helmut Jarausch
332 <jarausch@igpm.rwth-aachen.de>. Note however that, since
333 it is impossible to predict the size of the compressed
334 data before doing the compression, the -B limit is a bit
337 7. Fixed a bug in reading the operator typed file/tape path for
338 the next volume in restore.
340 8. Implemented a "-F script" option to restore which permits the
341 user to specify a script which will be launched at the
342 beginning of each tape, useful for automatic programming of
343 tape changers for example. See the restore man page for the
344 script parameters and return codes.
346 9. Small fix for the QFA routines provided by Uwe Gohlke
347 <uwe@ugsoft.de>, and some recommendations for QFA uses in
350 10. Fixed the multivolume restoring where making a mistake
351 to the 'Mount next tape' prompt caused several blocks to
354 11. Enhanced the -e option of dump to take as a parameter a
355 comma separated list of inode numbers.
357 12. Added the -E option to dump which specify a file containing
358 inode numbers to exclude from the dump.
360 13. Fixed the compressed multi-volume dump + restore.
362 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
363 ==================================================================
365 1. Made dump report the number of blocks dumped per volume.
366 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
368 2. Fix a bug in dump where waiting too much at the 'change volumes'
369 question caused the volume to be rewritten. Thanks to
370 Graham Reed <greed@users.sourceforge.net> for reporting the
371 bug and providing a patch.
373 3. Added a compression option to dump, contributed by Jerry
374 Peters <gapeters@worldnet.att.net>.
376 WARNING: the compression works only on files/pipes and
377 drives supporting variable block size.
379 WARNING2: tapes created using the compression feature are
380 incompatible with the standard dump tape format, and a
381 version of restore >= 0.4b22 will be needed for extraction.
383 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
384 architectures. Thanks to Paul Slootman <paul@debian.org> for
385 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
388 5. Many cleanups (CPP defines, const char warnings, check of
389 ext2fs COMPAT flags, time_t cleanups, added libext2 version
390 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
392 6. Made --prefix option work in configure. All the install path
393 are now based on the configure parameters.
395 7. Added the Quick File Access mode in dump/restore, contributed
396 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
397 a file tape position for each inode, and this file is used by
398 restore (if called with parameter Q and the filename)
399 to directly position the tape at the file restore is currently
400 working on. This saves hours when restoring single files from
401 large backups, saves the tapes and the drive's head. Use
402 --enable-qfa option of configure to compile in the QFA support.
404 8. Added the possibility to dump several files and directories
405 in a single invocation of dump. Thanks to Uwe Gohlke
406 <uwe@ugsoft.de> for implementing this option.
408 9. Fixed the dumping and restoring of files with holes
409 (files ending with holes didn't get dumped or restored
412 10. Fixed a socket descriptor leak in dump, which leaved opened
413 3 file descriptors per dump process (and there is one dump
416 11. Fixed dump large file system support, by explicit use of
417 open64/lseek64/etc functions (explicit use needed because
418 e2fsprogs libraries don't behave well when compiled with
419 FILE_OFFSET_BITS=64).
421 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
422 ======================================================================
424 1. Fixed some bugs in the dump -w|-W logic introduced by
425 the previous version. Thanks to Andreas Dilger
426 <adilger@turbolinux.com> for his help on this one.
428 2. Fixed again a compilation problem when using old e2fs
429 headers (filesystem label related). Thanks to many users
430 who reported this stupid error.
432 3. Fixed a build problem on old lib5 based systems dealing with
433 _PATH_MNTTAB being undefined. Thanks to John Adams
434 <johna@onevista.com> for reporting the bug.
436 4. Improved the error detection in restore when creating
437 the temporary files in TMPDIR. Now restore will corectly
438 report a 'no space left on device' error instead of
439 strange errors which could imply an archive corruption.
440 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
441 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
443 5. Added the throughput information in dump's progression
444 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
447 6. Use libext2fs's inode scanning routines, which are particularly
448 robust when dealing with errors (especially when having some
449 bad blocks on the filesystem). Many thanks to Colin
450 <colin@horizon.com> for reporting the bug, investigating
451 the issues, finding a workaround, writing the patch and
452 fully testing it... (of course, if this patch will break
453 anything, he is to blame for :-)).
455 7. Made dump and restore LFS aware. Dump can dump a filesystem
456 containing large files, generate a large file on output and
457 restore can restore them. This feature is not enabled by
458 default, use --enable-largefile option of configure to enable
459 it (you need to have a LFS aware glibc though). Thanks to
460 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
461 and to Theodore T'so <tytso@valinux.com> for his always
464 8. Made dump ask upon a tape write error if it should rewrite
465 the current volume (assume this is a bad tape) or if it should
466 assume an end-of-tape condition (useful for tape drives which
467 behaves badly at the end of the tape). Thanks to Andreas
468 Dilger <adilger@turbolinux.com> for the suggestion.
470 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
471 =======================================================================
473 1. Fixed a small compilation problem due to a change
474 in the definintion of the struct sigaction in
475 glibc 2.0 / libc5. Thanks to Gunther Schlegel
476 <schlegel@riege.de> for reporting the bug and to
477 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
480 2. Modified the label and uuid analysis in order to be
481 self-contained (independant of kernel/libc headers). This
482 should fix the compile with older kernel/libc headers and
483 will preserve the functionality. Thanks to Bernhard Erdmann
484 <bernhard.erdmann@gmx.de> for reporting the bug.
486 3. The 'exclude inode' option, if applied to a directory
487 inode, excludes now correctly all the leaves of this
488 directory. Thanks to John R. Dennison
489 <gerdesas@users.sourceforge.net> for reporting the bug.
491 4. Fixed the '-e' option to disable the possibility
492 to exclude the root inode (which causes the dumps to
493 be unreadable by restore). Prevented array overflow
494 when multiple -e options are used.
496 5. Fixed dump to correctly interpret a filesystem argument
497 which is a mountpoint and it is not an absolute path
498 (as specified in the fstab). Thanks to Bernhard R. Erdmann
499 <be@berdmann.de> for reporting the bug.
501 6. Made dump able to backup files larger than 2 GB. Note that
502 dump still doesn't cope with files larger than 4 GB.
504 7. Restore the real uid and gid before invoking an external
505 RSH program (big hole when dump or restore is suid root!).
507 8. Get the values for the default tape device and the location
508 of fstab file from the system headers. Thanks to
509 Andreas Dilger <adilger@turbolinux.com> for the patch.
511 9. Made dump -w|-W report all recognized filesystems
512 present in either /etc/fstab or /etc/dumpdates, and present
513 the list in the same order as in fstab file. Thanks
514 to Andreas Dilger <adilger@turbolinux.com> for the patch.
516 10. Made dump's -a (automatic end of tape detection) the
517 default. Specifying one of -B, -c, -d or -s options will
518 override the EOM detection. Thanks to Andreas Dilger
519 <adilger@turbolinux.com> for the patch.
521 11. Save the ext2 filesystem label into the dump volume label.
522 Specifying a volume label on the command line (-L option)
523 will override this feature. Thanks to Andreas Dilger
524 <adilger@turbolinux.com> for the patch.
526 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
527 =====================================================================
529 1. Fixed the signal handling in dump (which I broke in 0.4b17)
530 which was causing several strange dump failures (dump
531 hanged or segmentation faults etc).
533 2. Specified the default blocksize in the dump man page.
535 3. Changed two info messages of restore to be written on stdout
536 instead of stderr in order to leave stderr only for errors
537 or warnings. Thanks to Stephen Atwell
538 <satwell@urbana.css.mot.com> for the suggestion.
540 4. Corrected an off by one calculation which prevented
541 dumping a directory having a 1 character name length.
542 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
543 for reporting the bug.
545 5. Reinforce dump in order to allow only level 0 and no
546 -u option when dumping a subdirectory, and document
547 this in the man page. Thanks to Bernhard Erdmann
548 <bernhard.erdmann@gmx.de> for reporting the bug.
550 6. Fixed a small harmless bug in restore which caused
551 in some conditions hard links to be restored several
552 times (therefore generation some warning messages).
553 Thanks to Kenneth Porter <shiva@well.com> for
556 7. Updated the RPM spec file to the latest RedHat version,
557 providing FHS packaging and other cosmetic changes.
558 You will need RPM version >= 3.0.5 in order to build the RPM.
560 8. Updated the configure script to check for libtermcap
561 before checking for libreadline, because we need this
562 library in order to compile the readline support.
564 9. Made dump understand the LABEL= and UUID= notation
565 both in /etc/fstab and on the command line. Note that
566 you will need the /proc filesystem in order to use
567 these notations. Thanks to Erik Troan <ewt@redhat.com>
568 for providing the patch.
570 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
571 ===================================================================
573 1. Fixed a potential buffer overflow in restore. Thanks
574 to Stan Bubrouski <satan@fastdial.net> for reporting
577 2. Fixed a readline-related bug which prevented
578 'cat DUMPFILE | restore -i -f -' from working. Thanks
579 to Charles Karney <karney@users.sourceforge.net>
582 3. Changed a few "panic" into "exit", causing restore to
583 be more stable against some attacks (like the last one
584 reported on Bugtraq, although the last version of restore
585 was not vulnerable - just dumped core). Thanks to
586 Andreas Hasenack <andreas@conectiva.com.br> for reporting
589 4. Removed the suid-root bit on dump and restore in the
590 default build (and generated RPMs). It should be safer
591 now. Users who need the suid-root capabilities in order
592 to make network backups should read first the man page
593 of dump and enable the suid bit manually.
595 5. Added -ltermcap to the compile parameters for restore
596 when using readline support, in order to make the compile
597 process work on some systems (SuSE ?). Thanks to
598 Patrik Schindler <poc@pocnet.net> for reporting the bug.
600 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
601 ====================================================================
603 1. The -F script is called now *only* at the end of a tape,
604 not at the end of the dump. Thanks to Christian Haul
605 <haul@informatik.tu-darmstadt.de> for the bug report.
607 Normally, the device name and the current volume number
608 are passed on the command line of the script. However,
609 if you want the old style script (with no arguments
610 passed on the command line), you can enable it in
611 configure with the --enable-oldstylefscript.
613 2. Use posix signal handling to preserve dump functionality
614 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
617 3. Made the exit code of restore in case of a 'C'ompare
618 command reflect the result of the compare. An exit status
619 of 0 means the dump archive is correct, 1 means tape errors,
620 2 means that some files were modified. Thanks to Kenneth Porter
621 <shiva@well.com> for the suggestion.
623 4. Made (finally) quotes work in interactive restore.
625 5. Small fixes in order to allow dump to compile with a
626 really old e2fsprogs version. Thanks to Ian Zimmerman
627 <itz@speakeasy.org> for the bug report.
629 6. Add GNU readline capabilities to interactive restore.
630 Use configure's --enable-readline flag to enable this feature.
631 Thanks to Patrik Schindler <poc@pocnet.net> for the
634 7. Do the compare on the fly in restore 'C' mode (this will
635 allow not to exhaust the available /tmp space when
636 ccmparing large files). Thanks to Kenneth Porter
637 <shiva@well.com> for the suggestion.
639 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
640 ====================================================================
642 1. Fixed some several duplicate 'DUMP: DUMP:' in the
645 2. Corrected the estimation of blocks to dump. Note that
646 this is still wrong for large directory inodes, due
647 to the size of a BSD directory entry on the tape
648 (estimation is based on the size of the ext2 directory,
649 which is smaller because it doesn't contain the null
650 character at the end).
652 3. Made dump report the total number of MB written to
653 tape at the end of run. Thanks to W. Reilly Cooley
654 <wcooley@nakedape.cc> for the patch.
656 4. Added the -X option to restore giving the possibility
657 to read the names of the files to be extracted/listed
658 from a text file (in addition of the command line).
659 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
662 5. Added the device name and the current volume number
663 as arguments to the end of tape script (dump -F option).
665 6. Made the multi-volume dump work again (after having
666 broken it in 0.4b15).
668 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
669 ===================================================================
671 1. Added a prompt command in interactive restore mode. Thanks
672 to Andreas Dilger <adilger@home.com> for the patch.
674 2. Fixed a buffer overflow problem in dump (caused by
675 not checking the size of the filesystem parameter).
676 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
677 reporting this on Bugtraq (and to several dump users
678 who forwarded me his mail).
680 3. Added the '-F script' option to dump in order to
681 launch a script at the end of each tape (to be used
682 with a tape changer, or to notify the sysadmin by
685 4. Fixed a bug in restore compare code caused by the changes
688 5. Fixed the treatment of options using the old BSD syntax
689 in both dump and restore.
691 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
692 =======================================================================
694 1. Fixed a bug in dump which may have caused invalid deleted
695 directories to be dumped out if they were deleted after the
696 mapping pass. This could occure on active filesystem and lead
697 to heap corruption (causing dump malfunction in many possible ways).
698 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
699 bug and submitting the patch.
701 2. Fixed the handling of the filesystem parameter in dump. A
702 '/mnt/disk' parameter caused the disk contents to be dumped,
703 but a '/mnt/disk/' parameter caused the mountpoint directory
704 to be dumped (generally an empty directory).
706 3. Improved the output of dump in order to tell which directory
707 it is currently dumping (when dumping a subtree).
709 4. Added the '-e' exclude inode option to dump. Thanks to
710 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
712 5. Added a REPORTING-BUGS file in order to provide a guide
713 on how to correctly report a bug in dump/restore.
715 6. Fixed a restore problem when restoring a hard link to an inode
716 having the immutable or append-only attribute set. Thanks to
717 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
719 7. Fixed a compatibility problem between dumps made on little
720 endian machines (the format was correct) and big endian
721 machines (the format was incorrect). This fix break the
722 compatibility with the older dumps made on big endian
723 machines (sparc, m86k, ppc etc). For the first time in
724 linux dump's history (I believe), the dumps made by *BSD,
725 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
726 so interchangeable. Thanks to Rob Cermak
727 <cermak@ahab.rutgers.edu> for submitting the bug and
728 helping me test the fix.
730 8. Fixed the way dump reports the remaining percent/time, if
731 the number of blocks actually dumped exceeds the estimated
732 number of blocks. Thanks to Jean-Paul van der Jagt
733 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
735 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
736 ======================================================================
738 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
739 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
741 2. Removed the requirement to build the RPM as root from the
742 spec file. Thanks to Christian Weisgerber
743 <naddy@mips.rhein-neckar.de> for submitting this.
745 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
746 causing dump to block when dumping really huge filesystems.
747 Many thanks to Patrik Schindler <poc@pocnet.net> for
748 helping me find this bug.
750 4. Fixed the treatment for an interrupt signal when dump access
751 the remote tape through RSH. Thanks to Christian Weisgerber
752 <naddy@mips.rhein-neckar.de> for providing the patch.
754 5. Fixed a bug which was causing dump/restore to display
755 garbage characters instead of the remote host name.
757 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
758 =====================================================================
760 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
761 <kukuk@suse.de> for submitting the patch.
763 2. Fix for the exit code when using the size estimate option of
764 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
765 submitting the patch.
767 3. Handle EINTR in atomical reads/writes in dump, which was causing
768 dump to fail on some systems. Thanks to Eric Jergensen
769 <eric@dvns.com> for reporting the bug and submitting the patch.
771 4. Handle more than 16 characters for the device names in dumpdates.
772 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
773 tracking down the problem and proposing the solution.
775 5. Fixed a bug in dump which prevented the creation of the
776 dumpdates file when doing a 0-level dump without already
777 having a dumpdates file. Thanks to Patrik Schindler
778 <poc@pocnet.net> for reporting the bug.
780 6. Changed the way dump 'S' flag reports the size estimate
781 from number of blocks into bytes (making it compatible
782 with the Solaris version, and simplifying things for
783 amanda users). Thanks to Jason L Tibbitts III
784 <tibbs@math.uh.edu> for reporting the bug.
786 7. Fixed a compatibility problem in linux/alpha dump tape format.
787 Now the linux/alpha dump are (again) compatible with the
788 other dump formats. But this breaks compatibility with
789 older dumps made on alpha. Thanks to Mike Tibor
790 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
792 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
793 ======================================================================
795 1. Added a '--enable-kerberos' to configure.
797 2. Added a 'S' option to dump which determines the amount of space
798 that is needed to perform the dump without actually doing it, similar
799 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
800 <cermak@ahab.rutgers.edu>.
802 3. Added a 'M' multi-volume option to dump and restore which enables
803 dumping to multiple files (useful when dumping to an ext2
804 partition to make several dump files in order to bypass the 2GB
805 file size limitation). The 'f' argument is treated as a prefix and
806 the output files will be named <prefix>001, <prefix>002 etc. With
807 the 'M' flag, restore automatically selects the right file without
808 asking to enter a new tape each time.
810 4. Fixed a memory leak which was causing dump to grow very big
811 (270MB when dumping a 10GB filesystem...). Thanks to Jason
812 Fearon <jasonf@netrider.org.au> for reporting the bug.
814 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
815 ======================================================================
817 1. Make configure test if the system glob routines support
818 extended syntax (ALTDIRFUNC). If not, use the internal glob
819 routines instead of system ones. Thanks to Bernhard Sadlowski
820 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
821 and helping me resolve this and other minor libc5 compiling
824 2. Fix a problem when dumping a ext2fs with the 'filetype'
825 feature enabled. Thanks to Patrick J. LoPresti
826 <patl@cag.lcs.mit.edu> for reporting the bug and to
827 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
829 3. Made the nodump flag work on directories. A directory which
830 has the nodump flag gets never dumped, regardless of its
833 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
834 which allows dump on an active ext3 filesystem. However, this
835 is a "quick and dirty" patch which enables backup of an ext3
836 filesystem through the ext2 compatibility (by ignoring the
837 NEEDS_RECOVERY bit). The journal file is not recognized and
838 it is dumped (it should not).
840 5. Test the superblock compatibility flags when dumping, in order
841 to be sure that we know how to deal with specific features.
843 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
844 ====================================================================
846 1. Use lchown instead of chown, fixing a possible security problem
847 when restoring symlinks (a malicious user could use this
848 to deliberately corrupt the ownership of important system files).
849 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
850 this and providing the patch.
852 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
853 ====================================================================
855 1. Put dump sources under CVS, added Id tags in all files so
856 one can use 'ident' on binary files.
858 2. Added the dump/restore version in the usage text so one can
859 easily verify the version he is using.
861 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
862 a va_start/va_end problem on linux-ppc (always call va_start
863 va_end in pairs each time we use a vararg function).
865 4. Added again the DT_* constants because old libc does not
866 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
867 for submitting the bug report.
869 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
870 this should enable dumping big (huge) filesystems.
872 6. Added the RSH environment variable in order to be able to
873 use a rsh replacement like ssh when doing remote backups (and
874 bypass the security limitations of rcmd). Now you can do remote
875 backups without being root (or making dump setuid root).
877 7. Modified again the way dumpdates works. For incremental dumps,
878 we need to read dumpdates even if we are not using 'u' option.
879 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
882 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
883 ===================================================================
885 1. Removed the 'k' flag from the restore 'about' text if kerberos
888 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
889 to them (fsetflags takes a char*, setflags an open fd!).
891 3. (f)setflags is called only if the flags aren't empty. If the
892 file is a special file, a warning is printed, because changing
893 flags implies opening the device. Normally, a special file
894 should not have any flag... (Debian bug #29775, patch provided
895 by Abhijit Dasgupta <abhijit@ans.net>).
897 4. Made possible to dump a file system not mentioned in /etc/fstab.
898 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
900 5. Changed the default behaviour to not create dumpdates
901 unless 'u' option is specified. Removed the old "debian-patch"
902 which provided the same thing. (Debian bug #38136, #33818).
904 6. Removed all those dump*announce, since they were getting old...
906 7. Added warning messages if dumpdates does not exist and
907 when an inferior level dump does not exist (except for a level 0
910 8. Debugged the glob calls in interactive mode: restore used a
911 dirent struct which was different from the /usr/include/dirent.h
912 one (this used to work, is it a glibc2 change?), so none of the
913 compat glob (which used /usr/include/dirent.h) or the system glob
914 worked. Restore use now the system dirent (and the system
915 DT_* constants), which are compatible with BSD ones.
917 9. Added a configure flag (--with-dumpdatespath) to specify
918 the location of dumpdates file. By default, it is
921 10. Added the "AUTHOR" and "AVAILABILITY" sections and
922 included the current date/version in man pages.
924 11. Corrected the estimation of remaining time when
925 the operator doesn't change the tapes quickly enough. This
926 was an old bug, I thought I corrected it, and discovered
927 that in fact it was corrected in two different places, so
928 the results canceled each other...
930 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
931 ===================================================================
933 1. Integrated multiple patches from RedHat, Debian and SuSE:
935 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
937 - several fixes in the man pages.
938 - update the default tape device to /dev/st0.
939 - many updates for Linux Alpha (byte ordering, size_t etc).
941 - use environment variable for TMPDIR (instead of /tmp).
942 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
943 - workaround egcs bug (RedHat bugs #4281 and #2989).
944 - wire $(OPT) throughout Makefile's.
946 2. Upgrade the dump revision to 1, making possible to dump filesystems
947 made with e2fsprogs-1.15 or newer. Nothing seems to break...
949 3. Fix some compile warnings, prototype all functions.
951 4. Use glibc err/glob instead of internal compatibility
952 routines (only if available).
954 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
955 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
957 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
958 ======================================================================
960 1. Integrated the changes from FreeBSD-3.1-RELEASE
961 (mostly bug fixes, buffer overruns, dump has now an "automatic
962 tape length calculation" flag, dump/restore can use kerberos now
963 (this is NOT tested), use environment variables for TAPE and
966 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
968 3. Corrected a bug in restore when using 'C' option with multi-volumes
969 tapes (files splited accros two tapes give "size changed" errors
972 4. Corrected the long standing bug when dumping multiple tapes.
973 This works for me, needs further testing.
975 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
976 ====================================================================
978 1. Dump now runs correctly on kernels 2.1.x
979 Fix made by Gerald Peters <gapeters@worldnet.att.net>
981 Changes between versions 0.4b2 and 0.4b3
982 ========================================
984 1. Use realpath() if available
988 Changes between versions 0.4b1 and 0.4b2
989 ========================================
991 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
994 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
996 3. Fixed configure.in to correctly handle --enable-rmt
998 Changes between versions 0.3 and 0.4b1
999 ======================================
1001 1. Integrated the changes from 4.4BSD-Lite2
1003 2. Integrated the patches from Debian and Red Hat
1005 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1007 4. Changed dump to use the Ext2fs library to get block addresses. This
1008 should solve the endianness problem on SparcLinux.
1010 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1011 distribution's one) to use autoconf
1013 6. Fixed a few minor bugs
1015 Changes between versions 0.2e and 0.2f
1016 ======================================
1018 1. Added the creation of named pipes (fifos) in restore.
1020 2. Added the -N flag in the restore manual page.
1022 3. Added the file kernel.patch which contains the llseek() optimization
1023 patch for 1.2.x kernels.
1025 4. Fixed a bug in the restoration of symbolic links: owner and group were
1028 5. Integrated some changes from FreeBSD 2.2.
1030 6. Added a call to ftruncate() after restoring each file to restore
1031 correctly files ending by a hole.
1033 Changes between versions 0.2d and 0.2e
1034 ======================================
1036 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1037 with owner = root (0) and group = root/wheel/whatever (0).
1039 Changes between versions 0.2c and 0.2d
1040 ======================================
1042 1. Dump is now able to backup 2GB+ filesystems.
1044 2. Dump and restore can now be linked as static binaries.
1046 Changes between versions 0.2b and 0.2c
1047 ======================================
1049 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1051 Changes between versions 0.2a and 0.2b
1052 ======================================
1054 1. Really fixed the bug that I should have corrected in 0.2a.
1056 2. Enabled optimization again.
1058 Changes between versions 0.2 and 0.2a
1059 =====================================
1061 1. Disabled the optimization during compilation.
1063 Changes between versions 0.1 and 0.2
1064 ====================================
1066 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1067 the fs_type field (actually, I modified the file fstab.c to make it
1068 use the mntent functions).
1070 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1071 made by dump should be readable by the BSD restore and backups made
1072 by the BSD dump should be readable by restore. Unfortunately, this
1073 means that the dump format has changed between version 0.1 and version
1076 3. Dump is now able to backup a subtree, it is no longer limited to whole
1077 filesystems like the BSD version.
1079 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1082 Changes between versions 0.0 and 0.1
1083 ====================================
1085 1. Now create links rdump and rrestore during the `make install' step.
1087 2. Linux port specific bugs added to the manual pages
1089 3. Incorrect estimation of the number of tapes blocks fixed when doing
1090 incremental backups.
1092 4. Better ls-like format in restore in interactive mode.
