3 Changes between versions 0.4b29 and 0.4b30 (released ????????????????)
4 ======================================================================
6 1. Made dump print out the ext2 logical block number in case of a read
7 error, which can be given as an argument to debugfs' ncheck command,
8 in order to find out the affected inode. Added note about this
9 usage in dump's man page.
11 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
12 ==================================================================
14 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
15 non Linux clients were misinterpreted. The description of the problem
16 (incompatible numbering in Linux mtio opcodes) is documented at
17 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
18 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
19 providing an excellent, cross-platform replacement for rmt in his
22 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
23 which caused restore to fail when the inode maps were not entirely
24 contained on the first volume (when using really small volumes or
25 when dumping a huge number of inodes).
27 3. Fixed a problem in dump, where files in subdirectories of directories
28 that have the nodump flag set (or being excluded with -e/-E) were
29 sometimes incorrectly dumped (instead of being excluded). The original
30 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
31 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
32 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
33 help testing the patch.
35 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
36 which makes one able to pipe the output of dump, by the net, to
37 a remote CD-burner server.
39 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
40 and use GNU's symbolic syntax over rmt instead of numerical values
41 to assure multiple platform compatibility.
43 6. Documented the -d option in restore.
45 7. Added a -v (verbose) mode to dump. For now it just prints the number
46 of the inode being dumped, but this could evolve in future versions
47 to include interesting debugging output.
49 8. Added a -o flag to restore, which automatically restores the current
50 directory permissions in -i or -x mode, without asking the operator
51 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
52 and Peter Samuel <peters@e-smith.com>.
54 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
55 ====================================================================
57 1. Fixed a bug in the QFA feature which could have caused
58 a bad tape positionning on restore (causing extra delays in
59 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
61 2. Added a small note in the dump man page specifying that
62 there should be no white space between the option letter and
63 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
65 3. Made restore work with older versions of the readline library,
66 by checking in configure for several extended symbols. Restore
67 can now be compiled with a readline as old as the 2.0 release
68 (though it may be a good idea to upgrade it to a more recent
69 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
70 reporting the build failures.
72 4. Fixed a performance problem with the QFA file creation in
73 dump, which made unnecessary seeks on the tape slowing down
74 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
77 5. Removed the inclusion of some kernel headers in the dump
78 source, which prevented the compile in some kernel/glibc
79 headers/architecture combination. Thanks to Bdale Garbee
80 <bdale@gag.com> for reporting the bug.
82 6. Added the appropriate error message when dump fails to
83 open the output file for writing. Thanks to Amith Varghese
84 <amithv@yahoo.com> for reporting this bug.
86 7. Made restore able to understand large Solaris ufsdump tapes
87 (containing inodes bigger than 4194304). Sun have introduced
88 an "extension" to the dump tape format when dealing with
89 those inodes, which was uncorrectly handled by Linux restore.
90 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
91 providing a test case.
93 8. Added the -m parameter to dump which optimises the output for
94 inodes having been changed but not modified since the last dump
95 ('changed' and 'modified' have the meaning defined in stat(2)).
96 For those inodes, dump will save only the metadata, instead of
97 saving the entire inode contents. Inodes which are either
98 directories or have been modified since the last dump are saved
99 in a regular way. Uses of this flag must be consistent, meaning
100 that either every dump in an incremental dump set have the flag,
103 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
104 =======================================================================
106 1. Fixed behaviour of dump when exceeding resource limits
109 2. Added the -L flag to restore to allow the user to specify a
110 maximal allowed number of miscompares when using restore
111 with the -C option to check the backup.
113 3. Detailed the manual entry for the -N option of restore.
115 4. Added the -a flag to restore to make able doing unattended
116 restores in -i or -x mode (automatically walks through the
117 multiple dump volumes).
119 5. Extended the QFA mode to work with local files and/or
120 remote tapes and files. This way, restore can know in advance
121 the tape number and the offset for the inodes to extract and
122 can minimize the extraction time by seeking directly to the
125 6. Added the -A <archive> option to both dump and restore,
126 which makes dump to archive a dump table-of-contents in
127 the specified file to be used by restore to determine
128 whether a file is in the dump file that is being restored.
129 (the archive file syntax is also compatible with the
130 Solaris ufsdump generated one).
132 7. Small fix in restore making it able to read some (broken ?)
133 Solaris ufsdump tapes.
135 8. Fixed dump to correctly recognise the root filesystem when using
136 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
137 for reporting this bug.
139 9. Added the -P <file> option to restore to create a
140 Quick File Access file from an already made dump. Patch
141 contributed by Uwe Gohlke <uwe@ugsoft.de>.
143 10. Made restore compile and run on Solaris, making it a
144 possible replacement for the standard ufsrestore. Port was
145 contributed by Uwe Gohlke <uwe@ugsoft.de>.
147 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
148 =====================================================================
150 1. Added a set of backup scripts from Eugenio Diaz
151 <getnito@yahoo.com> in the examples section. It features
152 automatic (cron based) full and incremental dumping of
153 several filesystems on a separate filesystem.
155 2. Fixed a off-by-one miscalculation which disabled dumping
156 a one letter subdirectory. Thanks to Chris Siebenmann
157 <cks@utcc.utoronto.ca> for reporting the bug.
159 3. Fixed several restore bugs occuring when trying to
160 restore some missing files on the tape. Thanks to Chris
161 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
163 4. Fixed --with-ldopts configure argument passing, installing from
164 a separate object directory, makefile cleanups contributed
165 by <splite@purdue.edu>.
167 5. Fix a bug which could caused, in some conditions, the highest
168 number inode of a filesystem, to not be dumped. Many thanks
169 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
172 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
173 =======================================================================
175 1. Added a mini howto from Patrick Walsh in the examples
178 2. Minor man pages syntax corrections. Thanks to
179 Chris Danis <screechco@home.com> for reporting the bugs.
181 3. Added a script from David B. Peterson <dave@toppledwagon.com>
182 to the examples section. It features dumping several
183 filesystems to a remote tape drive upon ssh.
185 4. Added a patch provided by Richard Jones <rich@annexia.org>
186 which allows BRADEMAX (number of read errors tolerated by
187 dump) to be adjusted using the -I option.
189 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
190 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
193 6. Add the -l option to restore to specify if, when doing a
194 remote restore, the file used to access the backup is a
195 regular file (the defaults being a tape drive). Restore needs
196 to know this information when reading a remote compressed
197 dump. Previously, this information was autodetected, but
198 the autodetection code fails (with ioctl: Inappropriate ioctl
199 for device) when using a non Linux remote box. Thanks to
200 many users and especially to Eros Albertazzi
201 <eros@lamel.bo.cnr.it> for reporting this.
203 7. Found a workaroung for the dump deadlock problem (3 childs
204 stuck in pause(), father in read()). The workaround seems
205 to work for me and several beta-testers. If it doesn't work
206 for you, please report back.
208 8. Updated the RPM spec file (BuildPrereq, URL etc).
210 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
211 ========================================================================
213 1. Fixed the permissions of a newly created QFA file by dump.
215 2. Cleaned up the source of dump (the external variables
216 definition was a complete mess, making possible to have
219 3. Fixed restore to use the full tape volume path when doing
220 a compare (since it changes the working directory to the
221 filesystem being compared in the process).
223 4. Added the -q option to dump which makes dump abort
224 whenever it needs operator attention. It should be
225 easier to use dump in scripts with this option.
227 5. Detect the use of incompatible options to dump and
228 refuse them (like -a and -B options together).
230 6. Added bzip2 compression to dump/restore (use option -j level
231 to select it). Note that you will need a restore version
232 >= 0.4b24 in order to restore a bzip2 compressed dump.
233 The same warning as for the zlib compression applies:
234 the tape format of a bzip2 dump is not compatible with the
235 original BSD tape format.
237 7. Fixed a overflow problem in dump corrupting the dump when
238 very large files were encountered. Thanks to Vladimir Nadvornik
241 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
242 kernel buffer/page cache before starting the dump, helping
243 a bit those who use dump on mounted filesystems. Thanks to
244 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
247 9. Updated the RPM spec file following the RedHat changes
248 (dynamically linked binaries now in /usr/sbin etc).
250 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
251 which enables restore to recognise multi volume compressed dumps
252 done on CD. Included his scripts for dump (which pipe the dump
253 output directly into cdrecord) and restore. There is now
254 possible to to backups to CD on the fly!
256 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
257 ===================================================================
259 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
260 Marcus Meissner (Caldera International Security Dept.).
262 2. Implement the Sun rmt extended protocol. Patch submitted
263 by Ian Gordon <iangordon@users.sourceforge.net>.
265 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
266 the linux kernel header. This ensures that dump always has the
267 latest version of this file. Patch submitted by
268 Andreas Dilger <adilger@turbolinux.com>.
270 4. Report any filesystem present in either /etc/fstab with a
271 positive passno or /etc/dumpdates in dump -w output.
272 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
274 5. Fixed the looping problem in dump introduced in the
277 6. Changed the -B option of dump to limit the size of
278 _compressed_ output per volume if compression is on.
279 Patch contributed by Helmut Jarausch
280 <jarausch@igpm.rwth-aachen.de>. Note however that, since
281 it is impossible to predict the size of the compressed
282 data before doing the compression, the -B limit is a bit
285 7. Fixed a bug in reading the operator typed file/tape path for
286 the next volume in restore.
288 8. Implemented a "-F script" option to restore which permits the
289 user to specify a script which will be launched at the
290 beginning of each tape, useful for automatic programming of
291 tape changers for example. See the restore man page for the
292 script parameters and return codes.
294 9. Small fix for the QFA routines provided by Uwe Gohlke
295 <uwe@ugsoft.de>, and some recommendations for QFA uses in
298 10. Fixed the multivolume restoring where making a mistake
299 to the 'Mount next tape' prompt caused several blocks to
302 11. Enhanced the -e option of dump to take as a parameter a
303 comma separated list of inode numbers.
305 12. Added the -E option to dump which specify a file containing
306 inode numbers to exclude from the dump.
308 13. Fixed the compressed multi-volume dump + restore.
310 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
311 ==================================================================
313 1. Made dump report the number of blocks dumped per volume.
314 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
316 2. Fix a bug in dump where waiting too much at the 'change volumes'
317 question caused the volume to be rewritten. Thanks to
318 Graham Reed <greed@users.sourceforge.net> for reporting the
319 bug and providing a patch.
321 3. Added a compression option to dump, contributed by Jerry
322 Peters <gapeters@worldnet.att.net>.
324 WARNING: the compression works only on files/pipes and
325 drives supporting variable block size.
327 WARNING2: tapes created using the compression feature are
328 incompatible with the standard dump tape format, and a
329 version of restore >= 0.4b22 will be needed for extraction.
331 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
332 architectures. Thanks to Paul Slootman <paul@debian.org> for
333 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
336 5. Many cleanups (CPP defines, const char warnings, check of
337 ext2fs COMPAT flags, time_t cleanups, added libext2 version
338 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
340 6. Made --prefix option work in configure. All the install path
341 are now based on the configure parameters.
343 7. Added the Quick File Access mode in dump/restore, contributed
344 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
345 a file tape position for each inode, and this file is used by
346 restore (if called with parameter Q and the filename)
347 to directly position the tape at the file restore is currently
348 working on. This saves hours when restoring single files from
349 large backups, saves the tapes and the drive's head. Use
350 --enable-qfa option of configure to compile in the QFA support.
352 8. Added the possibility to dump several files and directories
353 in a single invocation of dump. Thanks to Uwe Gohlke
354 <uwe@ugsoft.de> for implementing this option.
356 9. Fixed the dumping and restoring of files with holes
357 (files ending with holes didn't get dumped or restored
360 10. Fixed a socket descriptor leak in dump, which leaved opened
361 3 file descriptors per dump process (and there is one dump
364 11. Fixed dump large file system support, by explicit use of
365 open64/lseek64/etc functions (explicit use needed because
366 e2fsprogs libraries don't behave well when compiled with
367 FILE_OFFSET_BITS=64).
369 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
370 ======================================================================
372 1. Fixed some bugs in the dump -w|-W logic introduced by
373 the previous version. Thanks to Andreas Dilger
374 <adilger@turbolinux.com> for his help on this one.
376 2. Fixed again a compilation problem when using old e2fs
377 headers (filesystem label related). Thanks to many users
378 who reported this stupid error.
380 3. Fixed a build problem on old lib5 based systems dealing with
381 _PATH_MNTTAB being undefined. Thanks to John Adams
382 <johna@onevista.com> for reporting the bug.
384 4. Improved the error detection in restore when creating
385 the temporary files in TMPDIR. Now restore will corectly
386 report a 'no space left on device' error instead of
387 strange errors which could imply an archive corruption.
388 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
389 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
391 5. Added the throughput information in dump's progression
392 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
395 6. Use libext2fs's inode scanning routines, which are particularly
396 robust when dealing with errors (especially when having some
397 bad blocks on the filesystem). Many thanks to Colin
398 <colin@horizon.com> for reporting the bug, investigating
399 the issues, finding a workaround, writing the patch and
400 fully testing it... (of course, if this patch will break
401 anything, he is to blame for :-)).
403 7. Made dump and restore LFS aware. Dump can dump a filesystem
404 containing large files, generate a large file on output and
405 restore can restore them. This feature is not enabled by
406 default, use --enable-largefile option of configure to enable
407 it (you need to have a LFS aware glibc though). Thanks to
408 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
409 and to Theodore T'so <tytso@valinux.com> for his always
412 8. Made dump ask upon a tape write error if it should rewrite
413 the current volume (assume this is a bad tape) or if it should
414 assume an end-of-tape condition (useful for tape drives which
415 behaves badly at the end of the tape). Thanks to Andreas
416 Dilger <adilger@turbolinux.com> for the suggestion.
418 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
419 =======================================================================
421 1. Fixed a small compilation problem due to a change
422 in the definintion of the struct sigaction in
423 glibc 2.0 / libc5. Thanks to Gunther Schlegel
424 <schlegel@riege.de> for reporting the bug and to
425 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
428 2. Modified the label and uuid analysis in order to be
429 self-contained (independant of kernel/libc headers). This
430 should fix the compile with older kernel/libc headers and
431 will preserve the functionality. Thanks to Bernhard Erdmann
432 <bernhard.erdmann@gmx.de> for reporting the bug.
434 3. The 'exclude inode' option, if applied to a directory
435 inode, excludes now correctly all the leaves of this
436 directory. Thanks to John R. Dennison
437 <gerdesas@users.sourceforge.net> for reporting the bug.
439 4. Fixed the '-e' option to disable the possibility
440 to exclude the root inode (which causes the dumps to
441 be unreadable by restore). Prevented array overflow
442 when multiple -e options are used.
444 5. Fixed dump to correctly interpret a filesystem argument
445 which is a mountpoint and it is not an absolute path
446 (as specified in the fstab). Thanks to Bernhard R. Erdmann
447 <be@berdmann.de> for reporting the bug.
449 6. Made dump able to backup files larger than 2 GB. Note that
450 dump still doesn't cope with files larger than 4 GB.
452 7. Restore the real uid and gid before invoking an external
453 RSH program (big hole when dump or restore is suid root!).
455 8. Get the values for the default tape device and the location
456 of fstab file from the system headers. Thanks to
457 Andreas Dilger <adilger@turbolinux.com> for the patch.
459 9. Made dump -w|-W report all recognized filesystems
460 present in either /etc/fstab or /etc/dumpdates, and present
461 the list in the same order as in fstab file. Thanks
462 to Andreas Dilger <adilger@turbolinux.com> for the patch.
464 10. Made dump's -a (automatic end of tape detection) the
465 default. Specifying one of -B, -c, -d or -s options will
466 override the EOM detection. Thanks to Andreas Dilger
467 <adilger@turbolinux.com> for the patch.
469 11. Save the ext2 filesystem label into the dump volume label.
470 Specifying a volume label on the command line (-L option)
471 will override this feature. Thanks to Andreas Dilger
472 <adilger@turbolinux.com> for the patch.
474 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
475 =====================================================================
477 1. Fixed the signal handling in dump (which I broke in 0.4b17)
478 which was causing several strange dump failures (dump
479 hanged or segmentation faults etc).
481 2. Specified the default blocksize in the dump man page.
483 3. Changed two info messages of restore to be written on stdout
484 instead of stderr in order to leave stderr only for errors
485 or warnings. Thanks to Stephen Atwell
486 <satwell@urbana.css.mot.com> for the suggestion.
488 4. Corrected an off by one calculation which prevented
489 dumping a directory having a 1 character name length.
490 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
491 for reporting the bug.
493 5. Reinforce dump in order to allow only level 0 and no
494 -u option when dumping a subdirectory, and document
495 this in the man page. Thanks to Bernhard Erdmann
496 <bernhard.erdmann@gmx.de> for reporting the bug.
498 6. Fixed a small harmless bug in restore which caused
499 in some conditions hard links to be restored several
500 times (therefore generation some warning messages).
501 Thanks to Kenneth Porter <shiva@well.com> for
504 7. Updated the RPM spec file to the latest RedHat version,
505 providing FHS packaging and other cosmetic changes.
506 You will need RPM version >= 3.0.5 in order to build the RPM.
508 8. Updated the configure script to check for libtermcap
509 before checking for libreadline, because we need this
510 library in order to compile the readline support.
512 9. Made dump understand the LABEL= and UUID= notation
513 both in /etc/fstab and on the command line. Note that
514 you will need the /proc filesystem in order to use
515 these notations. Thanks to Erik Troan <ewt@redhat.com>
516 for providing the patch.
518 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
519 ===================================================================
521 1. Fixed a potential buffer overflow in restore. Thanks
522 to Stan Bubrouski <satan@fastdial.net> for reporting
525 2. Fixed a readline-related bug which prevented
526 'cat DUMPFILE | restore -i -f -' from working. Thanks
527 to Charles Karney <karney@users.sourceforge.net>
530 3. Changed a few "panic" into "exit", causing restore to
531 be more stable against some attacks (like the last one
532 reported on Bugtraq, although the last version of restore
533 was not vulnerable - just dumped core). Thanks to
534 Andreas Hasenack <andreas@conectiva.com.br> for reporting
537 4. Removed the suid-root bit on dump and restore in the
538 default build (and generated RPMs). It should be safer
539 now. Users who need the suid-root capabilities in order
540 to make network backups should read first the man page
541 of dump and enable the suid bit manually.
543 5. Added -ltermcap to the compile parameters for restore
544 when using readline support, in order to make the compile
545 process work on some systems (SuSE ?). Thanks to
546 Patrik Schindler <poc@pocnet.net> for reporting the bug.
548 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
549 ====================================================================
551 1. The -F script is called now *only* at the end of a tape,
552 not at the end of the dump. Thanks to Christian Haul
553 <haul@informatik.tu-darmstadt.de> for the bug report.
555 Normally, the device name and the current volume number
556 are passed on the command line of the script. However,
557 if you want the old style script (with no arguments
558 passed on the command line), you can enable it in
559 configure with the --enable-oldstylefscript.
561 2. Use posix signal handling to preserve dump functionality
562 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
565 3. Made the exit code of restore in case of a 'C'ompare
566 command reflect the result of the compare. An exit status
567 of 0 means the dump archive is correct, 1 means tape errors,
568 2 means that some files were modified. Thanks to Kenneth Porter
569 <shiva@well.com> for the suggestion.
571 4. Made (finally) quotes work in interactive restore.
573 5. Small fixes in order to allow dump to compile with a
574 really old e2fsprogs version. Thanks to Ian Zimmerman
575 <itz@speakeasy.org> for the bug report.
577 6. Add GNU readline capabilities to interactive restore.
578 Use configure's --enable-readline flag to enable this feature.
579 Thanks to Patrik Schindler <poc@pocnet.net> for the
582 7. Do the compare on the fly in restore 'C' mode (this will
583 allow not to exhaust the available /tmp space when
584 ccmparing large files). Thanks to Kenneth Porter
585 <shiva@well.com> for the suggestion.
587 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
588 ====================================================================
590 1. Fixed some several duplicate 'DUMP: DUMP:' in the
593 2. Corrected the estimation of blocks to dump. Note that
594 this is still wrong for large directory inodes, due
595 to the size of a BSD directory entry on the tape
596 (estimation is based on the size of the ext2 directory,
597 which is smaller because it doesn't contain the null
598 character at the end).
600 3. Made dump report the total number of MB written to
601 tape at the end of run. Thanks to W. Reilly Cooley
602 <wcooley@nakedape.cc> for the patch.
604 4. Added the -X option to restore giving the possibility
605 to read the names of the files to be extracted/listed
606 from a text file (in addition of the command line).
607 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
610 5. Added the device name and the current volume number
611 as arguments to the end of tape script (dump -F option).
613 6. Made the multi-volume dump work again (after having
614 broken it in 0.4b15).
616 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
617 ===================================================================
619 1. Added a prompt command in interactive restore mode. Thanks
620 to Andreas Dilger <adilger@home.com> for the patch.
622 2. Fixed a buffer overflow problem in dump (caused by
623 not checking the size of the filesystem parameter).
624 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
625 reporting this on Bugtraq (and to several dump users
626 who forwarded me his mail).
628 3. Added the '-F script' option to dump in order to
629 launch a script at the end of each tape (to be used
630 with a tape changer, or to notify the sysadmin by
633 4. Fixed a bug in restore compare code caused by the changes
636 5. Fixed the treatment of options using the old BSD syntax
637 in both dump and restore.
639 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
640 =======================================================================
642 1. Fixed a bug in dump which may have caused invalid deleted
643 directories to be dumped out if they were deleted after the
644 mapping pass. This could occure on active filesystem and lead
645 to heap corruption (causing dump malfunction in many possible ways).
646 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
647 bug and submitting the patch.
649 2. Fixed the handling of the filesystem parameter in dump. A
650 '/mnt/disk' parameter caused the disk contents to be dumped,
651 but a '/mnt/disk/' parameter caused the mountpoint directory
652 to be dumped (generally an empty directory).
654 3. Improved the output of dump in order to tell which directory
655 it is currently dumping (when dumping a subtree).
657 4. Added the '-e' exclude inode option to dump. Thanks to
658 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
660 5. Added a REPORTING-BUGS file in order to provide a guide
661 on how to correctly report a bug in dump/restore.
663 6. Fixed a restore problem when restoring a hard link to an inode
664 having the immutable or append-only attribute set. Thanks to
665 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
667 7. Fixed a compatibility problem between dumps made on little
668 endian machines (the format was correct) and big endian
669 machines (the format was incorrect). This fix break the
670 compatibility with the older dumps made on big endian
671 machines (sparc, m86k, ppc etc). For the first time in
672 linux dump's history (I believe), the dumps made by *BSD,
673 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
674 so interchangeable. Thanks to Rob Cermak
675 <cermak@ahab.rutgers.edu> for submitting the bug and
676 helping me test the fix.
678 8. Fixed the way dump reports the remaining percent/time, if
679 the number of blocks actually dumped exceeds the estimated
680 number of blocks. Thanks to Jean-Paul van der Jagt
681 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
683 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
684 ======================================================================
686 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
687 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
689 2. Removed the requirement to build the RPM as root from the
690 spec file. Thanks to Christian Weisgerber
691 <naddy@mips.rhein-neckar.de> for submitting this.
693 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
694 causing dump to block when dumping really huge filesystems.
695 Many thanks to Patrik Schindler <poc@pocnet.net> for
696 helping me find this bug.
698 4. Fixed the treatment for an interrupt signal when dump access
699 the remote tape through RSH. Thanks to Christian Weisgerber
700 <naddy@mips.rhein-neckar.de> for providing the patch.
702 5. Fixed a bug which was causing dump/restore to display
703 garbage characters instead of the remote host name.
705 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
706 =====================================================================
708 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
709 <kukuk@suse.de> for submitting the patch.
711 2. Fix for the exit code when using the size estimate option of
712 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
713 submitting the patch.
715 3. Handle EINTR in atomical reads/writes in dump, which was causing
716 dump to fail on some systems. Thanks to Eric Jergensen
717 <eric@dvns.com> for reporting the bug and submitting the patch.
719 4. Handle more than 16 characters for the device names in dumpdates.
720 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
721 tracking down the problem and proposing the solution.
723 5. Fixed a bug in dump which prevented the creation of the
724 dumpdates file when doing a 0-level dump without already
725 having a dumpdates file. Thanks to Patrik Schindler
726 <poc@pocnet.net> for reporting the bug.
728 6. Changed the way dump 'S' flag reports the size estimate
729 from number of blocks into bytes (making it compatible
730 with the Solaris version, and simplifying things for
731 amanda users). Thanks to Jason L Tibbitts III
732 <tibbs@math.uh.edu> for reporting the bug.
734 7. Fixed a compatibility problem in linux/alpha dump tape format.
735 Now the linux/alpha dump are (again) compatible with the
736 other dump formats. But this breaks compatibility with
737 older dumps made on alpha. Thanks to Mike Tibor
738 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
740 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
741 ======================================================================
743 1. Added a '--enable-kerberos' to configure.
745 2. Added a 'S' option to dump which determines the amount of space
746 that is needed to perform the dump without actually doing it, similar
747 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
748 <cermak@ahab.rutgers.edu>.
750 3. Added a 'M' multi-volume option to dump and restore which enables
751 dumping to multiple files (useful when dumping to an ext2
752 partition to make several dump files in order to bypass the 2GB
753 file size limitation). The 'f' argument is treated as a prefix and
754 the output files will be named <prefix>001, <prefix>002 etc. With
755 the 'M' flag, restore automatically selects the right file without
756 asking to enter a new tape each time.
758 4. Fixed a memory leak which was causing dump to grow very big
759 (270MB when dumping a 10GB filesystem...). Thanks to Jason
760 Fearon <jasonf@netrider.org.au> for reporting the bug.
762 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
763 ======================================================================
765 1. Make configure test if the system glob routines support
766 extended syntax (ALTDIRFUNC). If not, use the internal glob
767 routines instead of system ones. Thanks to Bernhard Sadlowski
768 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
769 and helping me resolve this and other minor libc5 compiling
772 2. Fix a problem when dumping a ext2fs with the 'filetype'
773 feature enabled. Thanks to Patrick J. LoPresti
774 <patl@cag.lcs.mit.edu> for reporting the bug and to
775 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
777 3. Made the nodump flag work on directories. A directory which
778 has the nodump flag gets never dumped, regardless of its
781 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
782 which allows dump on an active ext3 filesystem. However, this
783 is a "quick and dirty" patch which enables backup of an ext3
784 filesystem through the ext2 compatibility (by ignoring the
785 NEEDS_RECOVERY bit). The journal file is not recognized and
786 it is dumped (it should not).
788 5. Test the superblock compatibility flags when dumping, in order
789 to be sure that we know how to deal with specific features.
791 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
792 ====================================================================
794 1. Use lchown instead of chown, fixing a possible security problem
795 when restoring symlinks (a malicious user could use this
796 to deliberately corrupt the ownership of important system files).
797 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
798 this and providing the patch.
800 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
801 ====================================================================
803 1. Put dump sources under CVS, added Id tags in all files so
804 one can use 'ident' on binary files.
806 2. Added the dump/restore version in the usage text so one can
807 easily verify the version he is using.
809 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
810 a va_start/va_end problem on linux-ppc (always call va_start
811 va_end in pairs each time we use a vararg function).
813 4. Added again the DT_* constants because old libc does not
814 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
815 for submitting the bug report.
817 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
818 this should enable dumping big (huge) filesystems.
820 6. Added the RSH environment variable in order to be able to
821 use a rsh replacement like ssh when doing remote backups (and
822 bypass the security limitations of rcmd). Now you can do remote
823 backups without being root (or making dump setuid root).
825 7. Modified again the way dumpdates works. For incremental dumps,
826 we need to read dumpdates even if we are not using 'u' option.
827 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
830 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
831 ===================================================================
833 1. Removed the 'k' flag from the restore 'about' text if kerberos
836 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
837 to them (fsetflags takes a char*, setflags an open fd!).
839 3. (f)setflags is called only if the flags aren't empty. If the
840 file is a special file, a warning is printed, because changing
841 flags implies opening the device. Normally, a special file
842 should not have any flag... (Debian bug #29775, patch provided
843 by Abhijit Dasgupta <abhijit@ans.net>).
845 4. Made possible to dump a file system not mentioned in /etc/fstab.
846 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
848 5. Changed the default behaviour to not create dumpdates
849 unless 'u' option is specified. Removed the old "debian-patch"
850 which provided the same thing. (Debian bug #38136, #33818).
852 6. Removed all those dump*announce, since they were getting old...
854 7. Added warning messages if dumpdates does not exist and
855 when an inferior level dump does not exist (except for a level 0
858 8. Debugged the glob calls in interactive mode: restore used a
859 dirent struct which was different from the /usr/include/dirent.h
860 one (this used to work, is it a glibc2 change?), so none of the
861 compat glob (which used /usr/include/dirent.h) or the system glob
862 worked. Restore use now the system dirent (and the system
863 DT_* constants), which are compatible with BSD ones.
865 9. Added a configure flag (--with-dumpdatespath) to specify
866 the location of dumpdates file. By default, it is
869 10. Added the "AUTHOR" and "AVAILABILITY" sections and
870 included the current date/version in man pages.
872 11. Corrected the estimation of remaining time when
873 the operator doesn't change the tapes quickly enough. This
874 was an old bug, I thought I corrected it, and discovered
875 that in fact it was corrected in two different places, so
876 the results canceled each other...
878 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
879 ===================================================================
881 1. Integrated multiple patches from RedHat, Debian and SuSE:
883 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
885 - several fixes in the man pages.
886 - update the default tape device to /dev/st0.
887 - many updates for Linux Alpha (byte ordering, size_t etc).
889 - use environment variable for TMPDIR (instead of /tmp).
890 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
891 - workaround egcs bug (RedHat bugs #4281 and #2989).
892 - wire $(OPT) throughout Makefile's.
894 2. Upgrade the dump revision to 1, making possible to dump filesystems
895 made with e2fsprogs-1.15 or newer. Nothing seems to break...
897 3. Fix some compile warnings, prototype all functions.
899 4. Use glibc err/glob instead of internal compatibility
900 routines (only if available).
902 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
903 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
905 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
906 ======================================================================
908 1. Integrated the changes from FreeBSD-3.1-RELEASE
909 (mostly bug fixes, buffer overruns, dump has now an "automatic
910 tape length calculation" flag, dump/restore can use kerberos now
911 (this is NOT tested), use environment variables for TAPE and
914 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
916 3. Corrected a bug in restore when using 'C' option with multi-volumes
917 tapes (files splited accros two tapes give "size changed" errors
920 4. Corrected the long standing bug when dumping multiple tapes.
921 This works for me, needs further testing.
923 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
924 ====================================================================
926 1. Dump now runs correctly on kernels 2.1.x
927 Fix made by Gerald Peters <gapeters@worldnet.att.net>
929 Changes between versions 0.4b2 and 0.4b3
930 ========================================
932 1. Use realpath() if available
936 Changes between versions 0.4b1 and 0.4b2
937 ========================================
939 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
942 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
944 3. Fixed configure.in to correctly handle --enable-rmt
946 Changes between versions 0.3 and 0.4b1
947 ======================================
949 1. Integrated the changes from 4.4BSD-Lite2
951 2. Integrated the patches from Debian and Red Hat
953 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
955 4. Changed dump to use the Ext2fs library to get block addresses. This
956 should solve the endianness problem on SparcLinux.
958 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
959 distribution's one) to use autoconf
961 6. Fixed a few minor bugs
963 Changes between versions 0.2e and 0.2f
964 ======================================
966 1. Added the creation of named pipes (fifos) in restore.
968 2. Added the -N flag in the restore manual page.
970 3. Added the file kernel.patch which contains the llseek() optimization
971 patch for 1.2.x kernels.
973 4. Fixed a bug in the restoration of symbolic links: owner and group were
976 5. Integrated some changes from FreeBSD 2.2.
978 6. Added a call to ftruncate() after restoring each file to restore
979 correctly files ending by a hole.
981 Changes between versions 0.2d and 0.2e
982 ======================================
984 1. Fixed a bug in the "set owner/mode" process. Every file was restored
985 with owner = root (0) and group = root/wheel/whatever (0).
987 Changes between versions 0.2c and 0.2d
988 ======================================
990 1. Dump is now able to backup 2GB+ filesystems.
992 2. Dump and restore can now be linked as static binaries.
994 Changes between versions 0.2b and 0.2c
995 ======================================
997 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
999 Changes between versions 0.2a and 0.2b
1000 ======================================
1002 1. Really fixed the bug that I should have corrected in 0.2a.
1004 2. Enabled optimization again.
1006 Changes between versions 0.2 and 0.2a
1007 =====================================
1009 1. Disabled the optimization during compilation.
1011 Changes between versions 0.1 and 0.2
1012 ====================================
1014 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1015 the fs_type field (actually, I modified the file fstab.c to make it
1016 use the mntent functions).
1018 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1019 made by dump should be readable by the BSD restore and backups made
1020 by the BSD dump should be readable by restore. Unfortunately, this
1021 means that the dump format has changed between version 0.1 and version
1024 3. Dump is now able to backup a subtree, it is no longer limited to whole
1025 filesystems like the BSD version.
1027 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1030 Changes between versions 0.0 and 0.1
1031 ====================================
1033 1. Now create links rdump and rrestore during the `make install' step.
1035 2. Linux port specific bugs added to the manual pages
1037 3. Incorrect estimation of the number of tapes blocks fixed when doing
1038 incremental backups.
1040 4. Better ls-like format in restore in interactive mode.
