3 Changes between versions 0.4b27 and 0.4b28 (released ?????????????????)
4 =======================================================================
6 1. Fixed a bug in the QFA feature which could have caused
7 a bad tape positionning on restore (causing extra delays in
8 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
10 2. Added a small note in the dump man page specifying that
11 there should be no white space between the option letter and
12 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
14 3. Made restore work with older versions of the readline library,
15 by checking in configure for several extended symbols. Restore
16 can now be compiled with a readline as old as the 2.0 release
17 (though it may be a good idea to upgrade it to a more recent
18 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
19 reporting the build failures.
21 4. Fixed a performance problem with the QFA file creation in
22 dump, which made unnecessary seeks on the tape slowing down
23 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
26 5. Removed the inclusion of some kernel headers in the dump
27 source, which prevented the compile in some kernel/glibc
28 headers/architecture combination. Thanks to Bdale Garbee
29 <bdale@gag.com> for reporting the bug.
31 6. Added the appropriate error message when dump fails to
32 open the output file for writing. Thanks to Amith Varghese
33 <amithv@yahoo.com> for reporting this bug.
35 7. Made restore able to understand large Solaris ufsdump tapes
36 (containing inodes bigger than 4194304). Sun have introduced
37 an "extension" to the dump tape format when dealing with
38 those inodes, which was uncorrectly handled by Linux restore.
39 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
40 providing a test case.
42 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
43 =======================================================================
45 1. Fixed behaviour of dump when exceeding resource limits
48 2. Added the -L flag to restore to allow the user to specify a
49 maximal allowed number of miscompares when using restore
50 with the -C option to check the backup.
52 3. Detailed the manual entry for the -N option of restore.
54 4. Added the -a flag to restore to make able doing unattended
55 restores in -i or -x mode (automatically walks through the
56 multiple dump volumes).
58 5. Extended the QFA mode to work with local files and/or
59 remote tapes and files. This way, restore can know in advance
60 the tape number and the offset for the inodes to extract and
61 can minimize the extraction time by seeking directly to the
64 6. Added the -A <archive> option to both dump and restore,
65 which makes dump to archive a dump table-of-contents in
66 the specified file to be used by restore to determine
67 whether a file is in the dump file that is being restored.
68 (the archive file syntax is also compatible with the
69 Solaris ufsdump generated one).
71 7. Small fix in restore making it able to read some (broken ?)
72 Solaris ufsdump tapes.
74 8. Fixed dump to correctly recognise the root filesystem when using
75 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
76 for reporting this bug.
78 9. Added the -P <file> option to restore to create a
79 Quick File Access file from an already made dump. Patch
80 contributed by Uwe Gohlke <uwe@ugsoft.de>.
82 10. Made restore compile and run on Solaris, making it a
83 possible replacement for the standard ufsrestore. Port was
84 contributed by Uwe Gohlke <uwe@ugsoft.de>.
86 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
87 =====================================================================
89 1. Added a set of backup scripts from Eugenio Diaz
90 <getnito@yahoo.com> in the examples section. It features
91 automatic (cron based) full and incremental dumping of
92 several filesystems on a separate filesystem.
94 2. Fixed a off-by-one miscalculation which disabled dumping
95 a one letter subdirectory. Thanks to Chris Siebenmann
96 <cks@utcc.utoronto.ca> for reporting the bug.
98 3. Fixed several restore bugs occuring when trying to
99 restore some missing files on the tape. Thanks to Chris
100 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
102 4. Fixed --with-ldopts configure argument passing, installing from
103 a separate object directory, makefile cleanups contributed
104 by <splite@purdue.edu>.
106 5. Fix a bug which could caused, in some conditions, the highest
107 number inode of a filesystem, to not be dumped. Many thanks
108 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
111 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
112 =======================================================================
114 1. Added a mini howto from Patrick Walsh in the examples
117 2. Minor man pages syntax corrections. Thanks to
118 Chris Danis <screechco@home.com> for reporting the bugs.
120 3. Added a script from David B. Peterson <dave@toppledwagon.com>
121 to the examples section. It features dumping several
122 filesystems to a remote tape drive upon ssh.
124 4. Added a patch provided by Richard Jones <rich@annexia.org>
125 which allows BRADEMAX (number of read errors tolerated by
126 dump) to be adjusted using the -I option.
128 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
129 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
132 6. Add the -l option to restore to specify if, when doing a
133 remote restore, the file used to access the backup is a
134 regular file (the defaults being a tape drive). Restore needs
135 to know this information when reading a remote compressed
136 dump. Previously, this information was autodetected, but
137 the autodetection code fails (with ioctl: Inappropriate ioctl
138 for device) when using a non Linux remote box. Thanks to
139 many users and especially to Eros Albertazzi
140 <eros@lamel.bo.cnr.it> for reporting this.
142 7. Found a workaroung for the dump deadlock problem (3 childs
143 stuck in pause(), father in read()). The workaround seems
144 to work for me and several beta-testers. If it doesn't work
145 for you, please report back.
147 8. Updated the RPM spec file (BuildPrereq, URL etc).
149 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
150 ========================================================================
152 1. Fixed the permissions of a newly created QFA file by dump.
154 2. Cleaned up the source of dump (the external variables
155 definition was a complete mess, making possible to have
158 3. Fixed restore to use the full tape volume path when doing
159 a compare (since it changes the working directory to the
160 filesystem being compared in the process).
162 4. Added the -q option to dump which makes dump abort
163 whenever it needs operator attention. It should be
164 easier to use dump in scripts with this option.
166 5. Detect the use of incompatible options to dump and
167 refuse them (like -a and -B options together).
169 6. Added bzip2 compression to dump/restore (use option -j level
170 to select it). Note that you will need a restore version
171 >= 0.4b24 in order to restore a bzip2 compressed dump.
172 The same warning as for the zlib compression applies:
173 the tape format of a bzip2 dump is not compatible with the
174 original BSD tape format.
176 7. Fixed a overflow problem in dump corrupting the dump when
177 very large files were encountered. Thanks to Vladimir Nadvornik
180 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
181 kernel buffer/page cache before starting the dump, helping
182 a bit those who use dump on mounted filesystems. Thanks to
183 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
186 9. Updated the RPM spec file following the RedHat changes
187 (dynamically linked binaries now in /usr/sbin etc).
189 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
190 which enables restore to recognise multi volume compressed dumps
191 done on CD. Included his scripts for dump (which pipe the dump
192 output directly into cdrecord) and restore. There is now
193 possible to to backups to CD on the fly!
195 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
196 ===================================================================
198 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
199 Marcus Meissner (Caldera International Security Dept.).
201 2. Implement the Sun rmt extended protocol. Patch submitted
202 by Ian Gordon <iangordon@users.sourceforge.net>.
204 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
205 the linux kernel header. This ensures that dump always has the
206 latest version of this file. Patch submitted by
207 Andreas Dilger <adilger@turbolinux.com>.
209 4. Report any filesystem present in either /etc/fstab with a
210 positive passno or /etc/dumpdates in dump -w output.
211 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
213 5. Fixed the looping problem in dump introduced in the
216 6. Changed the -B option of dump to limit the size of
217 _compressed_ output per volume if compression is on.
218 Patch contributed by Helmut Jarausch
219 <jarausch@igpm.rwth-aachen.de>. Note however that, since
220 it is impossible to predict the size of the compressed
221 data before doing the compression, the -B limit is a bit
224 7. Fixed a bug in reading the operator typed file/tape path for
225 the next volume in restore.
227 8. Implemented a "-F script" option to restore which permits the
228 user to specify a script which will be launched at the
229 beginning of each tape, useful for automatic programming of
230 tape changers for example. See the restore man page for the
231 script parameters and return codes.
233 9. Small fix for the QFA routines provided by Uwe Gohlke
234 <uwe@ugsoft.de>, and some recommendations for QFA uses in
237 10. Fixed the multivolume restoring where making a mistake
238 to the 'Mount next tape' prompt caused several blocks to
241 11. Enhanced the -e option of dump to take as a parameter a
242 comma separated list of inode numbers.
244 12. Added the -E option to dump which specify a file containing
245 inode numbers to exclude from the dump.
247 13. Fixed the compressed multi-volume dump + restore.
249 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
250 ==================================================================
252 1. Made dump report the number of blocks dumped per volume.
253 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
255 2. Fix a bug in dump where waiting too much at the 'change volumes'
256 question caused the volume to be rewritten. Thanks to
257 Graham Reed <greed@users.sourceforge.net> for reporting the
258 bug and providing a patch.
260 3. Added a compression option to dump, contributed by Jerry
261 Peters <gapeters@worldnet.att.net>.
263 WARNING: the compression works only on files/pipes and
264 drives supporting variable block size.
266 WARNING2: tapes created using the compression feature are
267 incompatible with the standard dump tape format, and a
268 version of restore >= 0.4b22 will be needed for extraction.
270 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
271 architectures. Thanks to Paul Slootman <paul@debian.org> for
272 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
275 5. Many cleanups (CPP defines, const char warnings, check of
276 ext2fs COMPAT flags, time_t cleanups, added libext2 version
277 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
279 6. Made --prefix option work in configure. All the install path
280 are now based on the configure parameters.
282 7. Added the Quick File Access mode in dump/restore, contributed
283 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
284 a file tape position for each inode, and this file is used by
285 restore (if called with parameter Q and the filename)
286 to directly position the tape at the file restore is currently
287 working on. This saves hours when restoring single files from
288 large backups, saves the tapes and the drive's head. Use
289 --enable-qfa option of configure to compile in the QFA support.
291 8. Added the possibility to dump several files and directories
292 in a single invocation of dump. Thanks to Uwe Gohlke
293 <uwe@ugsoft.de> for implementing this option.
295 9. Fixed the dumping and restoring of files with holes
296 (files ending with holes didn't get dumped or restored
299 10. Fixed a socket descriptor leak in dump, which leaved opened
300 3 file descriptors per dump process (and there is one dump
303 11. Fixed dump large file system support, by explicit use of
304 open64/lseek64/etc functions (explicit use needed because
305 e2fsprogs libraries don't behave well when compiled with
306 FILE_OFFSET_BITS=64).
308 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
309 ======================================================================
311 1. Fixed some bugs in the dump -w|-W logic introduced by
312 the previous version. Thanks to Andreas Dilger
313 <adilger@turbolinux.com> for his help on this one.
315 2. Fixed again a compilation problem when using old e2fs
316 headers (filesystem label related). Thanks to many users
317 who reported this stupid error.
319 3. Fixed a build problem on old lib5 based systems dealing with
320 _PATH_MNTTAB being undefined. Thanks to John Adams
321 <johna@onevista.com> for reporting the bug.
323 4. Improved the error detection in restore when creating
324 the temporary files in TMPDIR. Now restore will corectly
325 report a 'no space left on device' error instead of
326 strange errors which could imply an archive corruption.
327 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
328 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
330 5. Added the throughput information in dump's progression
331 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
334 6. Use libext2fs's inode scanning routines, which are particularly
335 robust when dealing with errors (especially when having some
336 bad blocks on the filesystem). Many thanks to Colin
337 <colin@horizon.com> for reporting the bug, investigating
338 the issues, finding a workaround, writing the patch and
339 fully testing it... (of course, if this patch will break
340 anything, he is to blame for :-)).
342 7. Made dump and restore LFS aware. Dump can dump a filesystem
343 containing large files, generate a large file on output and
344 restore can restore them. This feature is not enabled by
345 default, use --enable-largefile option of configure to enable
346 it (you need to have a LFS aware glibc though). Thanks to
347 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
348 and to Theodore T'so <tytso@valinux.com> for his always
351 8. Made dump ask upon a tape write error if it should rewrite
352 the current volume (assume this is a bad tape) or if it should
353 assume an end-of-tape condition (useful for tape drives which
354 behaves badly at the end of the tape). Thanks to Andreas
355 Dilger <adilger@turbolinux.com> for the suggestion.
357 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
358 =======================================================================
360 1. Fixed a small compilation problem due to a change
361 in the definintion of the struct sigaction in
362 glibc 2.0 / libc5. Thanks to Gunther Schlegel
363 <schlegel@riege.de> for reporting the bug and to
364 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
367 2. Modified the label and uuid analysis in order to be
368 self-contained (independant of kernel/libc headers). This
369 should fix the compile with older kernel/libc headers and
370 will preserve the functionality. Thanks to Bernhard Erdmann
371 <bernhard.erdmann@gmx.de> for reporting the bug.
373 3. The 'exclude inode' option, if applied to a directory
374 inode, excludes now correctly all the leaves of this
375 directory. Thanks to John R. Dennison
376 <gerdesas@users.sourceforge.net> for reporting the bug.
378 4. Fixed the '-e' option to disable the possibility
379 to exclude the root inode (which causes the dumps to
380 be unreadable by restore). Prevented array overflow
381 when multiple -e options are used.
383 5. Fixed dump to correctly interpret a filesystem argument
384 which is a mountpoint and it is not an absolute path
385 (as specified in the fstab). Thanks to Bernhard R. Erdmann
386 <be@berdmann.de> for reporting the bug.
388 6. Made dump able to backup files larger than 2 GB. Note that
389 dump still doesn't cope with files larger than 4 GB.
391 7. Restore the real uid and gid before invoking an external
392 RSH program (big hole when dump or restore is suid root!).
394 8. Get the values for the default tape device and the location
395 of fstab file from the system headers. Thanks to
396 Andreas Dilger <adilger@turbolinux.com> for the patch.
398 9. Made dump -w|-W report all recognized filesystems
399 present in either /etc/fstab or /etc/dumpdates, and present
400 the list in the same order as in fstab file. Thanks
401 to Andreas Dilger <adilger@turbolinux.com> for the patch.
403 10. Made dump's -a (automatic end of tape detection) the
404 default. Specifying one of -B, -c, -d or -s options will
405 override the EOM detection. Thanks to Andreas Dilger
406 <adilger@turbolinux.com> for the patch.
408 11. Save the ext2 filesystem label into the dump volume label.
409 Specifying a volume label on the command line (-L option)
410 will override this feature. Thanks to Andreas Dilger
411 <adilger@turbolinux.com> for the patch.
413 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
414 =====================================================================
416 1. Fixed the signal handling in dump (which I broke in 0.4b17)
417 which was causing several strange dump failures (dump
418 hanged or segmentation faults etc).
420 2. Specified the default blocksize in the dump man page.
422 3. Changed two info messages of restore to be written on stdout
423 instead of stderr in order to leave stderr only for errors
424 or warnings. Thanks to Stephen Atwell
425 <satwell@urbana.css.mot.com> for the suggestion.
427 4. Corrected an off by one calculation which prevented
428 dumping a directory having a 1 character name length.
429 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
430 for reporting the bug.
432 5. Reinforce dump in order to allow only level 0 and no
433 -u option when dumping a subdirectory, and document
434 this in the man page. Thanks to Bernhard Erdmann
435 <bernhard.erdmann@gmx.de> for reporting the bug.
437 6. Fixed a small harmless bug in restore which caused
438 in some conditions hard links to be restored several
439 times (therefore generation some warning messages).
440 Thanks to Kenneth Porter <shiva@well.com> for
443 7. Updated the RPM spec file to the latest RedHat version,
444 providing FHS packaging and other cosmetic changes.
445 You will need RPM version >= 3.0.5 in order to build the RPM.
447 8. Updated the configure script to check for libtermcap
448 before checking for libreadline, because we need this
449 library in order to compile the readline support.
451 9. Made dump understand the LABEL= and UUID= notation
452 both in /etc/fstab and on the command line. Note that
453 you will need the /proc filesystem in order to use
454 these notations. Thanks to Erik Troan <ewt@redhat.com>
455 for providing the patch.
457 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
458 ===================================================================
460 1. Fixed a potential buffer overflow in restore. Thanks
461 to Stan Bubrouski <satan@fastdial.net> for reporting
464 2. Fixed a readline-related bug which prevented
465 'cat DUMPFILE | restore -i -f -' from working. Thanks
466 to Charles Karney <karney@users.sourceforge.net>
469 3. Changed a few "panic" into "exit", causing restore to
470 be more stable against some attacks (like the last one
471 reported on Bugtraq, although the last version of restore
472 was not vulnerable - just dumped core). Thanks to
473 Andreas Hasenack <andreas@conectiva.com.br> for reporting
476 4. Removed the suid-root bit on dump and restore in the
477 default build (and generated RPMs). It should be safer
478 now. Users who need the suid-root capabilities in order
479 to make network backups should read first the man page
480 of dump and enable the suid bit manually.
482 5. Added -ltermcap to the compile parameters for restore
483 when using readline support, in order to make the compile
484 process work on some systems (SuSE ?). Thanks to
485 Patrik Schindler <poc@pocnet.net> for reporting the bug.
487 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
488 ====================================================================
490 1. The -F script is called now *only* at the end of a tape,
491 not at the end of the dump. Thanks to Christian Haul
492 <haul@informatik.tu-darmstadt.de> for the bug report.
494 Normally, the device name and the current volume number
495 are passed on the command line of the script. However,
496 if you want the old style script (with no arguments
497 passed on the command line), you can enable it in
498 configure with the --enable-oldstylefscript.
500 2. Use posix signal handling to preserve dump functionality
501 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
504 3. Made the exit code of restore in case of a 'C'ompare
505 command reflect the result of the compare. An exit status
506 of 0 means the dump archive is correct, 1 means tape errors,
507 2 means that some files were modified. Thanks to Kenneth Porter
508 <shiva@well.com> for the suggestion.
510 4. Made (finally) quotes work in interactive restore.
512 5. Small fixes in order to allow dump to compile with a
513 really old e2fsprogs version. Thanks to Ian Zimmerman
514 <itz@speakeasy.org> for the bug report.
516 6. Add GNU readline capabilities to interactive restore.
517 Use configure's --enable-readline flag to enable this feature.
518 Thanks to Patrik Schindler <poc@pocnet.net> for the
521 7. Do the compare on the fly in restore 'C' mode (this will
522 allow not to exhaust the available /tmp space when
523 ccmparing large files). Thanks to Kenneth Porter
524 <shiva@well.com> for the suggestion.
526 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
527 ====================================================================
529 1. Fixed some several duplicate 'DUMP: DUMP:' in the
532 2. Corrected the estimation of blocks to dump. Note that
533 this is still wrong for large directory inodes, due
534 to the size of a BSD directory entry on the tape
535 (estimation is based on the size of the ext2 directory,
536 which is smaller because it doesn't contain the null
537 character at the end).
539 3. Made dump report the total number of MB written to
540 tape at the end of run. Thanks to W. Reilly Cooley
541 <wcooley@nakedape.cc> for the patch.
543 4. Added the -X option to restore giving the possibility
544 to read the names of the files to be extracted/listed
545 from a text file (in addition of the command line).
546 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
549 5. Added the device name and the current volume number
550 as arguments to the end of tape script (dump -F option).
552 6. Made the multi-volume dump work again (after having
553 broken it in 0.4b15).
555 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
556 ===================================================================
558 1. Added a prompt command in interactive restore mode. Thanks
559 to Andreas Dilger <adilger@home.com> for the patch.
561 2. Fixed a buffer overflow problem in dump (caused by
562 not checking the size of the filesystem parameter).
563 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
564 reporting this on Bugtraq (and to several dump users
565 who forwarded me his mail).
567 3. Added the '-F script' option to dump in order to
568 launch a script at the end of each tape (to be used
569 with a tape changer, or to notify the sysadmin by
572 4. Fixed a bug in restore compare code caused by the changes
575 5. Fixed the treatment of options using the old BSD syntax
576 in both dump and restore.
578 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
579 =======================================================================
581 1. Fixed a bug in dump which may have caused invalid deleted
582 directories to be dumped out if they were deleted after the
583 mapping pass. This could occure on active filesystem and lead
584 to heap corruption (causing dump malfunction in many possible ways).
585 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
586 bug and submitting the patch.
588 2. Fixed the handling of the filesystem parameter in dump. A
589 '/mnt/disk' parameter caused the disk contents to be dumped,
590 but a '/mnt/disk/' parameter caused the mountpoint directory
591 to be dumped (generally an empty directory).
593 3. Improved the output of dump in order to tell which directory
594 it is currently dumping (when dumping a subtree).
596 4. Added the '-e' exclude inode option to dump. Thanks to
597 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
599 5. Added a REPORTING-BUGS file in order to provide a guide
600 on how to correctly report a bug in dump/restore.
602 6. Fixed a restore problem when restoring a hard link to an inode
603 having the immutable or append-only attribute set. Thanks to
604 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
606 7. Fixed a compatibility problem between dumps made on little
607 endian machines (the format was correct) and big endian
608 machines (the format was incorrect). This fix break the
609 compatibility with the older dumps made on big endian
610 machines (sparc, m86k, ppc etc). For the first time in
611 linux dump's history (I believe), the dumps made by *BSD,
612 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
613 so interchangeable. Thanks to Rob Cermak
614 <cermak@ahab.rutgers.edu> for submitting the bug and
615 helping me test the fix.
617 8. Fixed the way dump reports the remaining percent/time, if
618 the number of blocks actually dumped exceeds the estimated
619 number of blocks. Thanks to Jean-Paul van der Jagt
620 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
622 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
623 ======================================================================
625 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
626 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
628 2. Removed the requirement to build the RPM as root from the
629 spec file. Thanks to Christian Weisgerber
630 <naddy@mips.rhein-neckar.de> for submitting this.
632 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
633 causing dump to block when dumping really huge filesystems.
634 Many thanks to Patrik Schindler <poc@pocnet.net> for
635 helping me find this bug.
637 4. Fixed the treatment for an interrupt signal when dump access
638 the remote tape through RSH. Thanks to Christian Weisgerber
639 <naddy@mips.rhein-neckar.de> for providing the patch.
641 5. Fixed a bug which was causing dump/restore to display
642 garbage characters instead of the remote host name.
644 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
645 =====================================================================
647 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
648 <kukuk@suse.de> for submitting the patch.
650 2. Fix for the exit code when using the size estimate option of
651 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
652 submitting the patch.
654 3. Handle EINTR in atomical reads/writes in dump, which was causing
655 dump to fail on some systems. Thanks to Eric Jergensen
656 <eric@dvns.com> for reporting the bug and submitting the patch.
658 4. Handle more than 16 characters for the device names in dumpdates.
659 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
660 tracking down the problem and proposing the solution.
662 5. Fixed a bug in dump which prevented the creation of the
663 dumpdates file when doing a 0-level dump without already
664 having a dumpdates file. Thanks to Patrik Schindler
665 <poc@pocnet.net> for reporting the bug.
667 6. Changed the way dump 'S' flag reports the size estimate
668 from number of blocks into bytes (making it compatible
669 with the Solaris version, and simplifying things for
670 amanda users). Thanks to Jason L Tibbitts III
671 <tibbs@math.uh.edu> for reporting the bug.
673 7. Fixed a compatibility problem in linux/alpha dump tape format.
674 Now the linux/alpha dump are (again) compatible with the
675 other dump formats. But this breaks compatibility with
676 older dumps made on alpha. Thanks to Mike Tibor
677 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
679 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
680 ======================================================================
682 1. Added a '--enable-kerberos' to configure.
684 2. Added a 'S' option to dump which determines the amount of space
685 that is needed to perform the dump without actually doing it, similar
686 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
687 <cermak@ahab.rutgers.edu>.
689 3. Added a 'M' multi-volume option to dump and restore which enables
690 dumping to multiple files (useful when dumping to an ext2
691 partition to make several dump files in order to bypass the 2GB
692 file size limitation). The 'f' argument is treated as a prefix and
693 the output files will be named <prefix>001, <prefix>002 etc. With
694 the 'M' flag, restore automatically selects the right file without
695 asking to enter a new tape each time.
697 4. Fixed a memory leak which was causing dump to grow very big
698 (270MB when dumping a 10GB filesystem...). Thanks to Jason
699 Fearon <jasonf@netrider.org.au> for reporting the bug.
701 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
702 ======================================================================
704 1. Make configure test if the system glob routines support
705 extended syntax (ALTDIRFUNC). If not, use the internal glob
706 routines instead of system ones. Thanks to Bernhard Sadlowski
707 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
708 and helping me resolve this and other minor libc5 compiling
711 2. Fix a problem when dumping a ext2fs with the 'filetype'
712 feature enabled. Thanks to Patrick J. LoPresti
713 <patl@cag.lcs.mit.edu> for reporting the bug and to
714 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
716 3. Made the nodump flag work on directories. A directory which
717 has the nodump flag gets never dumped, regardless of its
720 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
721 which allows dump on an active ext3 filesystem. However, this
722 is a "quick and dirty" patch which enables backup of an ext3
723 filesystem through the ext2 compatibility (by ignoring the
724 NEEDS_RECOVERY bit). The journal file is not recognized and
725 it is dumped (it should not).
727 5. Test the superblock compatibility flags when dumping, in order
728 to be sure that we know how to deal with specific features.
730 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
731 ====================================================================
733 1. Use lchown instead of chown, fixing a possible security problem
734 when restoring symlinks (a malicious user could use this
735 to deliberately corrupt the ownership of important system files).
736 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
737 this and providing the patch.
739 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
740 ====================================================================
742 1. Put dump sources under CVS, added Id tags in all files so
743 one can use 'ident' on binary files.
745 2. Added the dump/restore version in the usage text so one can
746 easily verify the version he is using.
748 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
749 a va_start/va_end problem on linux-ppc (always call va_start
750 va_end in pairs each time we use a vararg function).
752 4. Added again the DT_* constants because old libc does not
753 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
754 for submitting the bug report.
756 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
757 this should enable dumping big (huge) filesystems.
759 6. Added the RSH environment variable in order to be able to
760 use a rsh replacement like ssh when doing remote backups (and
761 bypass the security limitations of rcmd). Now you can do remote
762 backups without being root (or making dump setuid root).
764 7. Modified again the way dumpdates works. For incremental dumps,
765 we need to read dumpdates even if we are not using 'u' option.
766 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
769 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
770 ===================================================================
772 1. Removed the 'k' flag from the restore 'about' text if kerberos
775 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
776 to them (fsetflags takes a char*, setflags an open fd!).
778 3. (f)setflags is called only if the flags aren't empty. If the
779 file is a special file, a warning is printed, because changing
780 flags implies opening the device. Normally, a special file
781 should not have any flag... (Debian bug #29775, patch provided
782 by Abhijit Dasgupta <abhijit@ans.net>).
784 4. Made possible to dump a file system not mentioned in /etc/fstab.
785 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
787 5. Changed the default behaviour to not create dumpdates
788 unless 'u' option is specified. Removed the old "debian-patch"
789 which provided the same thing. (Debian bug #38136, #33818).
791 6. Removed all those dump*announce, since they were getting old...
793 7. Added warning messages if dumpdates does not exist and
794 when an inferior level dump does not exist (except for a level 0
797 8. Debugged the glob calls in interactive mode: restore used a
798 dirent struct which was different from the /usr/include/dirent.h
799 one (this used to work, is it a glibc2 change?), so none of the
800 compat glob (which used /usr/include/dirent.h) or the system glob
801 worked. Restore use now the system dirent (and the system
802 DT_* constants), which are compatible with BSD ones.
804 9. Added a configure flag (--with-dumpdatespath) to specify
805 the location of dumpdates file. By default, it is
808 10. Added the "AUTHOR" and "AVAILABILITY" sections and
809 included the current date/version in man pages.
811 11. Corrected the estimation of remaining time when
812 the operator doesn't change the tapes quickly enough. This
813 was an old bug, I thought I corrected it, and discovered
814 that in fact it was corrected in two different places, so
815 the results canceled each other...
817 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
818 ===================================================================
820 1. Integrated multiple patches from RedHat, Debian and SuSE:
822 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
824 - several fixes in the man pages.
825 - update the default tape device to /dev/st0.
826 - many updates for Linux Alpha (byte ordering, size_t etc).
828 - use environment variable for TMPDIR (instead of /tmp).
829 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
830 - workaround egcs bug (RedHat bugs #4281 and #2989).
831 - wire $(OPT) throughout Makefile's.
833 2. Upgrade the dump revision to 1, making possible to dump filesystems
834 made with e2fsprogs-1.15 or newer. Nothing seems to break...
836 3. Fix some compile warnings, prototype all functions.
838 4. Use glibc err/glob instead of internal compatibility
839 routines (only if available).
841 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
842 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
844 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
845 ======================================================================
847 1. Integrated the changes from FreeBSD-3.1-RELEASE
848 (mostly bug fixes, buffer overruns, dump has now an "automatic
849 tape length calculation" flag, dump/restore can use kerberos now
850 (this is NOT tested), use environment variables for TAPE and
853 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
855 3. Corrected a bug in restore when using 'C' option with multi-volumes
856 tapes (files splited accros two tapes give "size changed" errors
859 4. Corrected the long standing bug when dumping multiple tapes.
860 This works for me, needs further testing.
862 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
863 ====================================================================
865 1. Dump now runs correctly on kernels 2.1.x
866 Fix made by Gerald Peters <gapeters@worldnet.att.net>
868 Changes between versions 0.4b2 and 0.4b3
869 ========================================
871 1. Use realpath() if available
875 Changes between versions 0.4b1 and 0.4b2
876 ========================================
878 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
881 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
883 3. Fixed configure.in to correctly handle --enable-rmt
885 Changes between versions 0.3 and 0.4b1
886 ======================================
888 1. Integrated the changes from 4.4BSD-Lite2
890 2. Integrated the patches from Debian and Red Hat
892 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
894 4. Changed dump to use the Ext2fs library to get block addresses. This
895 should solve the endianness problem on SparcLinux.
897 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
898 distribution's one) to use autoconf
900 6. Fixed a few minor bugs
902 Changes between versions 0.2e and 0.2f
903 ======================================
905 1. Added the creation of named pipes (fifos) in restore.
907 2. Added the -N flag in the restore manual page.
909 3. Added the file kernel.patch which contains the llseek() optimization
910 patch for 1.2.x kernels.
912 4. Fixed a bug in the restoration of symbolic links: owner and group were
915 5. Integrated some changes from FreeBSD 2.2.
917 6. Added a call to ftruncate() after restoring each file to restore
918 correctly files ending by a hole.
920 Changes between versions 0.2d and 0.2e
921 ======================================
923 1. Fixed a bug in the "set owner/mode" process. Every file was restored
924 with owner = root (0) and group = root/wheel/whatever (0).
926 Changes between versions 0.2c and 0.2d
927 ======================================
929 1. Dump is now able to backup 2GB+ filesystems.
931 2. Dump and restore can now be linked as static binaries.
933 Changes between versions 0.2b and 0.2c
934 ======================================
936 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
938 Changes between versions 0.2a and 0.2b
939 ======================================
941 1. Really fixed the bug that I should have corrected in 0.2a.
943 2. Enabled optimization again.
945 Changes between versions 0.2 and 0.2a
946 =====================================
948 1. Disabled the optimization during compilation.
950 Changes between versions 0.1 and 0.2
951 ====================================
953 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
954 the fs_type field (actually, I modified the file fstab.c to make it
955 use the mntent functions).
957 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
958 made by dump should be readable by the BSD restore and backups made
959 by the BSD dump should be readable by restore. Unfortunately, this
960 means that the dump format has changed between version 0.1 and version
963 3. Dump is now able to backup a subtree, it is no longer limited to whole
964 filesystems like the BSD version.
966 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
969 Changes between versions 0.0 and 0.1
970 ====================================
972 1. Now create links rdump and rrestore during the `make install' step.
974 2. Linux port specific bugs added to the manual pages
976 3. Incorrect estimation of the number of tapes blocks fixed when doing
979 4. Better ls-like format in restore in interactive mode.
