3 Changes between versions 0.4b26 and 0.4b27 (released ???????????????)
4 =====================================================================
6 1. Fixed behaviour of dump when exceeding resource limits
9 2. Added the -L flag to restore to allow the user to specify a
10 maximal allowed number of miscompares when using restore
11 with the -C option to check the backup.
13 3. Detailed the manual entry for the -N option of restore.
15 4. Added the -a flag to restore to make able doing unattended
16 restores in -i or -x mode (automatically walks through the
17 multiple dump volumes).
19 5. Extended the QFA mode to work with local files and/or
20 remote tapes and files. This way, restore can know in advance
21 the tape number and the offset for the inodes to extract and
22 can minimize the extraction time by seeking directly to the
25 6. Added the -A <archive> option to both dump and restore,
26 which makes dump to archive a dump table-of-contents in
27 the specified file to be used by restore to determine
28 whether a file is in the dump file that is being restored.
29 (the archive file syntax is also compatible with the
30 Solaris ufsdump generated one).
32 7. Small fix in restore making it able to read some (broken ?)
33 Solaris ufsdump tapes.
35 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
36 =====================================================================
38 1. Added a set of backup scripts from Eugenio Diaz
39 <getnito@yahoo.com> in the examples section. It features
40 automatic (cron based) full and incremental dumping of
41 several filesystems on a separate filesystem.
43 2. Fixed a off-by-one miscalculation which disabled dumping
44 a one letter subdirectory. Thanks to Chris Siebenmann
45 <cks@utcc.utoronto.ca> for reporting the bug.
47 3. Fixed several restore bugs occuring when trying to
48 restore some missing files on the tape. Thanks to Chris
49 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
51 4. Fixed --with-ldopts configure argument passing, installing from
52 a separate object directory, makefile cleanups contributed
53 by <splite@purdue.edu>.
55 5. Fix a bug which could caused, in some conditions, the highest
56 number inode of a filesystem, to not be dumped. Many thanks
57 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
60 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
61 =======================================================================
63 1. Added a mini howto from Patrick Walsh in the examples
66 2. Minor man pages syntax corrections. Thanks to
67 Chris Danis <screechco@home.com> for reporting the bugs.
69 3. Added a script from David B. Peterson <dave@toppledwagon.com>
70 to the examples section. It features dumping several
71 filesystems to a remote tape drive upon ssh.
73 4. Added a patch provided by Richard Jones <rich@annexia.org>
74 which allows BRADEMAX (number of read errors tolerated by
75 dump) to be adjusted using the -I option.
77 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
78 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
81 6. Add the -l option to restore to specify if, when doing a
82 remote restore, the file used to access the backup is a
83 regular file (the defaults being a tape drive). Restore needs
84 to know this information when reading a remote compressed
85 dump. Previously, this information was autodetected, but
86 the autodetection code fails (with ioctl: Inappropriate ioctl
87 for device) when using a non Linux remote box. Thanks to
88 many users and especially to Eros Albertazzi
89 <eros@lamel.bo.cnr.it> for reporting this.
91 7. Found a workaroung for the dump deadlock problem (3 childs
92 stuck in pause(), father in read()). The workaround seems
93 to work for me and several beta-testers. If it doesn't work
94 for you, please report back.
96 8. Updated the RPM spec file (BuildPrereq, URL etc).
98 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
99 ========================================================================
101 1. Fixed the permissions of a newly created QFA file by dump.
103 2. Cleaned up the source of dump (the external variables
104 definition was a complete mess, making possible to have
107 3. Fixed restore to use the full tape volume path when doing
108 a compare (since it changes the working directory to the
109 filesystem being compared in the process).
111 4. Added the -q option to dump which makes dump abort
112 whenever it needs operator attention. It should be
113 easier to use dump in scripts with this option.
115 5. Detect the use of incompatible options to dump and
116 refuse them (like -a and -B options together).
118 6. Added bzip2 compression to dump/restore (use option -j level
119 to select it). Note that you will need a restore version
120 >= 0.4b24 in order to restore a bzip2 compressed dump.
121 The same warning as for the zlib compression applies:
122 the tape format of a bzip2 dump is not compatible with the
123 original BSD tape format.
125 7. Fixed a overflow problem in dump corrupting the dump when
126 very large files were encountered. Thanks to Vladimir Nadvornik
129 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
130 kernel buffer/page cache before starting the dump, helping
131 a bit those who use dump on mounted filesystems. Thanks to
132 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
135 9. Updated the RPM spec file following the RedHat changes
136 (dynamically linked binaries now in /usr/sbin etc).
138 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
139 which enables restore to recognise multi volume compressed dumps
140 done on CD. Included his scripts for dump (which pipe the dump
141 output directly into cdrecord) and restore. There is now
142 possible to to backups to CD on the fly!
144 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
145 ===================================================================
147 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
148 Marcus Meissner (Caldera International Security Dept.).
150 2. Implement the Sun rmt extended protocol. Patch submitted
151 by Ian Gordon <iangordon@users.sourceforge.net>.
153 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
154 the linux kernel header. This ensures that dump always has the
155 latest version of this file. Patch submitted by
156 Andreas Dilger <adilger@turbolinux.com>.
158 4. Report any filesystem present in either /etc/fstab with a
159 positive passno or /etc/dumpdates in dump -w output.
160 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
162 5. Fixed the looping problem in dump introduced in the
165 6. Changed the -B option of dump to limit the size of
166 _compressed_ output per volume if compression is on.
167 Patch contributed by Helmut Jarausch
168 <jarausch@igpm.rwth-aachen.de>. Note however that, since
169 it is impossible to predict the size of the compressed
170 data before doing the compression, the -B limit is a bit
173 7. Fixed a bug in reading the operator typed file/tape path for
174 the next volume in restore.
176 8. Implemented a "-F script" option to restore which permits the
177 user to specify a script which will be launched at the
178 beginning of each tape, useful for automatic programming of
179 tape changers for example. See the restore man page for the
180 script parameters and return codes.
182 9. Small fix for the QFA routines provided by Uwe Gohlke
183 <uwe@ugsoft.de>, and some recommendations for QFA uses in
186 10. Fixed the multivolume restoring where making a mistake
187 to the 'Mount next tape' prompt caused several blocks to
190 11. Enhanced the -e option of dump to take as a parameter a
191 comma separated list of inode numbers.
193 12. Added the -E option to dump which specify a file containing
194 inode numbers to exclude from the dump.
196 13. Fixed the compressed multi-volume dump + restore.
198 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
199 ==================================================================
201 1. Made dump report the number of blocks dumped per volume.
202 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
204 2. Fix a bug in dump where waiting too much at the 'change volumes'
205 question caused the volume to be rewritten. Thanks to
206 Graham Reed <greed@users.sourceforge.net> for reporting the
207 bug and providing a patch.
209 3. Added a compression option to dump, contributed by Jerry
210 Peters <gapeters@worldnet.att.net>.
212 WARNING: the compression works only on files/pipes and
213 drives supporting variable block size.
215 WARNING2: tapes created using the compression feature are
216 incompatible with the standard dump tape format, and a
217 version of restore >= 0.4b22 will be needed for extraction.
219 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
220 architectures. Thanks to Paul Slootman <paul@debian.org> for
221 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
224 5. Many cleanups (CPP defines, const char warnings, check of
225 ext2fs COMPAT flags, time_t cleanups, added libext2 version
226 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
228 6. Made --prefix option work in configure. All the install path
229 are now based on the configure parameters.
231 7. Added the Quick File Access mode in dump/restore, contributed
232 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
233 a file tape position for each inode, and this file is used by
234 restore (if called with parameter Q and the filename)
235 to directly position the tape at the file restore is currently
236 working on. This saves hours when restoring single files from
237 large backups, saves the tapes and the drive's head. Use
238 --enable-qfa option of configure to compile in the QFA support.
240 8. Added the possibility to dump several files and directories
241 in a single invocation of dump. Thanks to Uwe Gohlke
242 <uwe@ugsoft.de> for implementing this option.
244 9. Fixed the dumping and restoring of files with holes
245 (files ending with holes didn't get dumped or restored
248 10. Fixed a socket descriptor leak in dump, which leaved opened
249 3 file descriptors per dump process (and there is one dump
252 11. Fixed dump large file system support, by explicit use of
253 open64/lseek64/etc functions (explicit use needed because
254 e2fsprogs libraries don't behave well when compiled with
255 FILE_OFFSET_BITS=64).
257 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
258 ======================================================================
260 1. Fixed some bugs in the dump -w|-W logic introduced by
261 the previous version. Thanks to Andreas Dilger
262 <adilger@turbolinux.com> for his help on this one.
264 2. Fixed again a compilation problem when using old e2fs
265 headers (filesystem label related). Thanks to many users
266 who reported this stupid error.
268 3. Fixed a build problem on old lib5 based systems dealing with
269 _PATH_MNTTAB being undefined. Thanks to John Adams
270 <johna@onevista.com> for reporting the bug.
272 4. Improved the error detection in restore when creating
273 the temporary files in TMPDIR. Now restore will corectly
274 report a 'no space left on device' error instead of
275 strange errors which could imply an archive corruption.
276 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
277 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
279 5. Added the throughput information in dump's progression
280 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
283 6. Use libext2fs's inode scanning routines, which are particularly
284 robust when dealing with errors (especially when having some
285 bad blocks on the filesystem). Many thanks to Colin
286 <colin@horizon.com> for reporting the bug, investigating
287 the issues, finding a workaround, writing the patch and
288 fully testing it... (of course, if this patch will break
289 anything, he is to blame for :-)).
291 7. Made dump and restore LFS aware. Dump can dump a filesystem
292 containing large files, generate a large file on output and
293 restore can restore them. This feature is not enabled by
294 default, use --enable-largefile option of configure to enable
295 it (you need to have a LFS aware glibc though). Thanks to
296 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
297 and to Theodore T'so <tytso@valinux.com> for his always
300 8. Made dump ask upon a tape write error if it should rewrite
301 the current volume (assume this is a bad tape) or if it should
302 assume an end-of-tape condition (useful for tape drives which
303 behaves badly at the end of the tape). Thanks to Andreas
304 Dilger <adilger@turbolinux.com> for the suggestion.
306 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
307 =======================================================================
309 1. Fixed a small compilation problem due to a change
310 in the definintion of the struct sigaction in
311 glibc 2.0 / libc5. Thanks to Gunther Schlegel
312 <schlegel@riege.de> for reporting the bug and to
313 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
316 2. Modified the label and uuid analysis in order to be
317 self-contained (independant of kernel/libc headers). This
318 should fix the compile with older kernel/libc headers and
319 will preserve the functionality. Thanks to Bernhard Erdmann
320 <bernhard.erdmann@gmx.de> for reporting the bug.
322 3. The 'exclude inode' option, if applied to a directory
323 inode, excludes now correctly all the leaves of this
324 directory. Thanks to John R. Dennison
325 <gerdesas@users.sourceforge.net> for reporting the bug.
327 4. Fixed the '-e' option to disable the possibility
328 to exclude the root inode (which causes the dumps to
329 be unreadable by restore). Prevented array overflow
330 when multiple -e options are used.
332 5. Fixed dump to correctly interpret a filesystem argument
333 which is a mountpoint and it is not an absolute path
334 (as specified in the fstab). Thanks to Bernhard R. Erdmann
335 <be@berdmann.de> for reporting the bug.
337 6. Made dump able to backup files larger than 2 GB. Note that
338 dump still doesn't cope with files larger than 4 GB.
340 7. Restore the real uid and gid before invoking an external
341 RSH program (big hole when dump or restore is suid root!).
343 8. Get the values for the default tape device and the location
344 of fstab file from the system headers. Thanks to
345 Andreas Dilger <adilger@turbolinux.com> for the patch.
347 9. Made dump -w|-W report all recognized filesystems
348 present in either /etc/fstab or /etc/dumpdates, and present
349 the list in the same order as in fstab file. Thanks
350 to Andreas Dilger <adilger@turbolinux.com> for the patch.
352 10. Made dump's -a (automatic end of tape detection) the
353 default. Specifying one of -B, -c, -d or -s options will
354 override the EOM detection. Thanks to Andreas Dilger
355 <adilger@turbolinux.com> for the patch.
357 11. Save the ext2 filesystem label into the dump volume label.
358 Specifying a volume label on the command line (-L option)
359 will override this feature. Thanks to Andreas Dilger
360 <adilger@turbolinux.com> for the patch.
362 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
363 =====================================================================
365 1. Fixed the signal handling in dump (which I broke in 0.4b17)
366 which was causing several strange dump failures (dump
367 hanged or segmentation faults etc).
369 2. Specified the default blocksize in the dump man page.
371 3. Changed two info messages of restore to be written on stdout
372 instead of stderr in order to leave stderr only for errors
373 or warnings. Thanks to Stephen Atwell
374 <satwell@urbana.css.mot.com> for the suggestion.
376 4. Corrected an off by one calculation which prevented
377 dumping a directory having a 1 character name length.
378 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
379 for reporting the bug.
381 5. Reinforce dump in order to allow only level 0 and no
382 -u option when dumping a subdirectory, and document
383 this in the man page. Thanks to Bernhard Erdmann
384 <bernhard.erdmann@gmx.de> for reporting the bug.
386 6. Fixed a small harmless bug in restore which caused
387 in some conditions hard links to be restored several
388 times (therefore generation some warning messages).
389 Thanks to Kenneth Porter <shiva@well.com> for
392 7. Updated the RPM spec file to the latest RedHat version,
393 providing FHS packaging and other cosmetic changes.
394 You will need RPM version >= 3.0.5 in order to build the RPM.
396 8. Updated the configure script to check for libtermcap
397 before checking for libreadline, because we need this
398 library in order to compile the readline support.
400 9. Made dump understand the LABEL= and UUID= notation
401 both in /etc/fstab and on the command line. Note that
402 you will need the /proc filesystem in order to use
403 these notations. Thanks to Erik Troan <ewt@redhat.com>
404 for providing the patch.
406 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
407 ===================================================================
409 1. Fixed a potential buffer overflow in restore. Thanks
410 to Stan Bubrouski <satan@fastdial.net> for reporting
413 2. Fixed a readline-related bug which prevented
414 'cat DUMPFILE | restore -i -f -' from working. Thanks
415 to Charles Karney <karney@users.sourceforge.net>
418 3. Changed a few "panic" into "exit", causing restore to
419 be more stable against some attacks (like the last one
420 reported on Bugtraq, although the last version of restore
421 was not vulnerable - just dumped core). Thanks to
422 Andreas Hasenack <andreas@conectiva.com.br> for reporting
425 4. Removed the suid-root bit on dump and restore in the
426 default build (and generated RPMs). It should be safer
427 now. Users who need the suid-root capabilities in order
428 to make network backups should read first the man page
429 of dump and enable the suid bit manually.
431 5. Added -ltermcap to the compile parameters for restore
432 when using readline support, in order to make the compile
433 process work on some systems (SuSE ?). Thanks to
434 Patrik Schindler <poc@pocnet.net> for reporting the bug.
436 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
437 ====================================================================
439 1. The -F script is called now *only* at the end of a tape,
440 not at the end of the dump. Thanks to Christian Haul
441 <haul@informatik.tu-darmstadt.de> for the bug report.
443 Normally, the device name and the current volume number
444 are passed on the command line of the script. However,
445 if you want the old style script (with no arguments
446 passed on the command line), you can enable it in
447 configure with the --enable-oldstylefscript.
449 2. Use posix signal handling to preserve dump functionality
450 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
453 3. Made the exit code of restore in case of a 'C'ompare
454 command reflect the result of the compare. An exit status
455 of 0 means the dump archive is correct, 1 means tape errors,
456 2 means that some files were modified. Thanks to Kenneth Porter
457 <shiva@well.com> for the suggestion.
459 4. Made (finally) quotes work in interactive restore.
461 5. Small fixes in order to allow dump to compile with a
462 really old e2fsprogs version. Thanks to Ian Zimmerman
463 <itz@speakeasy.org> for the bug report.
465 6. Add GNU readline capabilities to interactive restore.
466 Use configure's --enable-readline flag to enable this feature.
467 Thanks to Patrik Schindler <poc@pocnet.net> for the
470 7. Do the compare on the fly in restore 'C' mode (this will
471 allow not to exhaust the available /tmp space when
472 ccmparing large files). Thanks to Kenneth Porter
473 <shiva@well.com> for the suggestion.
475 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
476 ====================================================================
478 1. Fixed some several duplicate 'DUMP: DUMP:' in the
481 2. Corrected the estimation of blocks to dump. Note that
482 this is still wrong for large directory inodes, due
483 to the size of a BSD directory entry on the tape
484 (estimation is based on the size of the ext2 directory,
485 which is smaller because it doesn't contain the null
486 character at the end).
488 3. Made dump report the total number of MB written to
489 tape at the end of run. Thanks to W. Reilly Cooley
490 <wcooley@nakedape.cc> for the patch.
492 4. Added the -X option to restore giving the possibility
493 to read the names of the files to be extracted/listed
494 from a text file (in addition of the command line).
495 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
498 5. Added the device name and the current volume number
499 as arguments to the end of tape script (dump -F option).
501 6. Made the multi-volume dump work again (after having
502 broken it in 0.4b15).
504 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
505 ===================================================================
507 1. Added a prompt command in interactive restore mode. Thanks
508 to Andreas Dilger <adilger@home.com> for the patch.
510 2. Fixed a buffer overflow problem in dump (caused by
511 not checking the size of the filesystem parameter).
512 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
513 reporting this on Bugtraq (and to several dump users
514 who forwarded me his mail).
516 3. Added the '-F script' option to dump in order to
517 launch a script at the end of each tape (to be used
518 with a tape changer, or to notify the sysadmin by
521 4. Fixed a bug in restore compare code caused by the changes
524 5. Fixed the treatment of options using the old BSD syntax
525 in both dump and restore.
527 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
528 =======================================================================
530 1. Fixed a bug in dump which may have caused invalid deleted
531 directories to be dumped out if they were deleted after the
532 mapping pass. This could occure on active filesystem and lead
533 to heap corruption (causing dump malfunction in many possible ways).
534 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
535 bug and submitting the patch.
537 2. Fixed the handling of the filesystem parameter in dump. A
538 '/mnt/disk' parameter caused the disk contents to be dumped,
539 but a '/mnt/disk/' parameter caused the mountpoint directory
540 to be dumped (generally an empty directory).
542 3. Improved the output of dump in order to tell which directory
543 it is currently dumping (when dumping a subtree).
545 4. Added the '-e' exclude inode option to dump. Thanks to
546 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
548 5. Added a REPORTING-BUGS file in order to provide a guide
549 on how to correctly report a bug in dump/restore.
551 6. Fixed a restore problem when restoring a hard link to an inode
552 having the immutable or append-only attribute set. Thanks to
553 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
555 7. Fixed a compatibility problem between dumps made on little
556 endian machines (the format was correct) and big endian
557 machines (the format was incorrect). This fix break the
558 compatibility with the older dumps made on big endian
559 machines (sparc, m86k, ppc etc). For the first time in
560 linux dump's history (I believe), the dumps made by *BSD,
561 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
562 so interchangeable. Thanks to Rob Cermak
563 <cermak@ahab.rutgers.edu> for submitting the bug and
564 helping me test the fix.
566 8. Fixed the way dump reports the remaining percent/time, if
567 the number of blocks actually dumped exceeds the estimated
568 number of blocks. Thanks to Jean-Paul van der Jagt
569 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
571 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
572 ======================================================================
574 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
575 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
577 2. Removed the requirement to build the RPM as root from the
578 spec file. Thanks to Christian Weisgerber
579 <naddy@mips.rhein-neckar.de> for submitting this.
581 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
582 causing dump to block when dumping really huge filesystems.
583 Many thanks to Patrik Schindler <poc@pocnet.net> for
584 helping me find this bug.
586 4. Fixed the treatment for an interrupt signal when dump access
587 the remote tape through RSH. Thanks to Christian Weisgerber
588 <naddy@mips.rhein-neckar.de> for providing the patch.
590 5. Fixed a bug which was causing dump/restore to display
591 garbage characters instead of the remote host name.
593 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
594 =====================================================================
596 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
597 <kukuk@suse.de> for submitting the patch.
599 2. Fix for the exit code when using the size estimate option of
600 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
601 submitting the patch.
603 3. Handle EINTR in atomical reads/writes in dump, which was causing
604 dump to fail on some systems. Thanks to Eric Jergensen
605 <eric@dvns.com> for reporting the bug and submitting the patch.
607 4. Handle more than 16 characters for the device names in dumpdates.
608 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
609 tracking down the problem and proposing the solution.
611 5. Fixed a bug in dump which prevented the creation of the
612 dumpdates file when doing a 0-level dump without already
613 having a dumpdates file. Thanks to Patrik Schindler
614 <poc@pocnet.net> for reporting the bug.
616 6. Changed the way dump 'S' flag reports the size estimate
617 from number of blocks into bytes (making it compatible
618 with the Solaris version, and simplifying things for
619 amanda users). Thanks to Jason L Tibbitts III
620 <tibbs@math.uh.edu> for reporting the bug.
622 7. Fixed a compatibility problem in linux/alpha dump tape format.
623 Now the linux/alpha dump are (again) compatible with the
624 other dump formats. But this breaks compatibility with
625 older dumps made on alpha. Thanks to Mike Tibor
626 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
628 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
629 ======================================================================
631 1. Added a '--enable-kerberos' to configure.
633 2. Added a 'S' option to dump which determines the amount of space
634 that is needed to perform the dump without actually doing it, similar
635 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
636 <cermak@ahab.rutgers.edu>.
638 3. Added a 'M' multi-volume option to dump and restore which enables
639 dumping to multiple files (useful when dumping to an ext2
640 partition to make several dump files in order to bypass the 2GB
641 file size limitation). The 'f' argument is treated as a prefix and
642 the output files will be named <prefix>001, <prefix>002 etc. With
643 the 'M' flag, restore automatically selects the right file without
644 asking to enter a new tape each time.
646 4. Fixed a memory leak which was causing dump to grow very big
647 (270MB when dumping a 10GB filesystem...). Thanks to Jason
648 Fearon <jasonf@netrider.org.au> for reporting the bug.
650 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
651 ======================================================================
653 1. Make configure test if the system glob routines support
654 extended syntax (ALTDIRFUNC). If not, use the internal glob
655 routines instead of system ones. Thanks to Bernhard Sadlowski
656 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
657 and helping me resolve this and other minor libc5 compiling
660 2. Fix a problem when dumping a ext2fs with the 'filetype'
661 feature enabled. Thanks to Patrick J. LoPresti
662 <patl@cag.lcs.mit.edu> for reporting the bug and to
663 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
665 3. Made the nodump flag work on directories. A directory which
666 has the nodump flag gets never dumped, regardless of its
669 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
670 which allows dump on an active ext3 filesystem. However, this
671 is a "quick and dirty" patch which enables backup of an ext3
672 filesystem through the ext2 compatibility (by ignoring the
673 NEEDS_RECOVERY bit). The journal file is not recognized and
674 it is dumped (it should not).
676 5. Test the superblock compatibility flags when dumping, in order
677 to be sure that we know how to deal with specific features.
679 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
680 ====================================================================
682 1. Use lchown instead of chown, fixing a possible security problem
683 when restoring symlinks (a malicious user could use this
684 to deliberately corrupt the ownership of important system files).
685 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
686 this and providing the patch.
688 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
689 ====================================================================
691 1. Put dump sources under CVS, added Id tags in all files so
692 one can use 'ident' on binary files.
694 2. Added the dump/restore version in the usage text so one can
695 easily verify the version he is using.
697 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
698 a va_start/va_end problem on linux-ppc (always call va_start
699 va_end in pairs each time we use a vararg function).
701 4. Added again the DT_* constants because old libc does not
702 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
703 for submitting the bug report.
705 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
706 this should enable dumping big (huge) filesystems.
708 6. Added the RSH environment variable in order to be able to
709 use a rsh replacement like ssh when doing remote backups (and
710 bypass the security limitations of rcmd). Now you can do remote
711 backups without being root (or making dump setuid root).
713 7. Modified again the way dumpdates works. For incremental dumps,
714 we need to read dumpdates even if we are not using 'u' option.
715 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
718 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
719 ===================================================================
721 1. Removed the 'k' flag from the restore 'about' text if kerberos
724 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
725 to them (fsetflags takes a char*, setflags an open fd!).
727 3. (f)setflags is called only if the flags aren't empty. If the
728 file is a special file, a warning is printed, because changing
729 flags implies opening the device. Normally, a special file
730 should not have any flag... (Debian bug #29775, patch provided
731 by Abhijit Dasgupta <abhijit@ans.net>).
733 4. Made possible to dump a file system not mentioned in /etc/fstab.
734 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
736 5. Changed the default behaviour to not create dumpdates
737 unless 'u' option is specified. Removed the old "debian-patch"
738 which provided the same thing. (Debian bug #38136, #33818).
740 6. Removed all those dump*announce, since they were getting old...
742 7. Added warning messages if dumpdates does not exist and
743 when an inferior level dump does not exist (except for a level 0
746 8. Debugged the glob calls in interactive mode: restore used a
747 dirent struct which was different from the /usr/include/dirent.h
748 one (this used to work, is it a glibc2 change?), so none of the
749 compat glob (which used /usr/include/dirent.h) or the system glob
750 worked. Restore use now the system dirent (and the system
751 DT_* constants), which are compatible with BSD ones.
753 9. Added a configure flag (--with-dumpdatespath) to specify
754 the location of dumpdates file. By default, it is
757 10. Added the "AUTHOR" and "AVAILABILITY" sections and
758 included the current date/version in man pages.
760 11. Corrected the estimation of remaining time when
761 the operator doesn't change the tapes quickly enough. This
762 was an old bug, I thought I corrected it, and discovered
763 that in fact it was corrected in two different places, so
764 the results canceled each other...
766 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
767 ===================================================================
769 1. Integrated multiple patches from RedHat, Debian and SuSE:
771 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
773 - several fixes in the man pages.
774 - update the default tape device to /dev/st0.
775 - many updates for Linux Alpha (byte ordering, size_t etc).
777 - use environment variable for TMPDIR (instead of /tmp).
778 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
779 - workaround egcs bug (RedHat bugs #4281 and #2989).
780 - wire $(OPT) throughout Makefile's.
782 2. Upgrade the dump revision to 1, making possible to dump filesystems
783 made with e2fsprogs-1.15 or newer. Nothing seems to break...
785 3. Fix some compile warnings, prototype all functions.
787 4. Use glibc err/glob instead of internal compatibility
788 routines (only if available).
790 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
791 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
793 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
794 ======================================================================
796 1. Integrated the changes from FreeBSD-3.1-RELEASE
797 (mostly bug fixes, buffer overruns, dump has now an "automatic
798 tape length calculation" flag, dump/restore can use kerberos now
799 (this is NOT tested), use environment variables for TAPE and
802 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
804 3. Corrected a bug in restore when using 'C' option with multi-volumes
805 tapes (files splited accros two tapes give "size changed" errors
808 4. Corrected the long standing bug when dumping multiple tapes.
809 This works for me, needs further testing.
811 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
812 ====================================================================
814 1. Dump now runs correctly on kernels 2.1.x
815 Fix made by Gerald Peters <gapeters@worldnet.att.net>
817 Changes between versions 0.4b2 and 0.4b3
818 ========================================
820 1. Use realpath() if available
824 Changes between versions 0.4b1 and 0.4b2
825 ========================================
827 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
830 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
832 3. Fixed configure.in to correctly handle --enable-rmt
834 Changes between versions 0.3 and 0.4b1
835 ======================================
837 1. Integrated the changes from 4.4BSD-Lite2
839 2. Integrated the patches from Debian and Red Hat
841 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
843 4. Changed dump to use the Ext2fs library to get block addresses. This
844 should solve the endianness problem on SparcLinux.
846 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
847 distribution's one) to use autoconf
849 6. Fixed a few minor bugs
851 Changes between versions 0.2e and 0.2f
852 ======================================
854 1. Added the creation of named pipes (fifos) in restore.
856 2. Added the -N flag in the restore manual page.
858 3. Added the file kernel.patch which contains the llseek() optimization
859 patch for 1.2.x kernels.
861 4. Fixed a bug in the restoration of symbolic links: owner and group were
864 5. Integrated some changes from FreeBSD 2.2.
866 6. Added a call to ftruncate() after restoring each file to restore
867 correctly files ending by a hole.
869 Changes between versions 0.2d and 0.2e
870 ======================================
872 1. Fixed a bug in the "set owner/mode" process. Every file was restored
873 with owner = root (0) and group = root/wheel/whatever (0).
875 Changes between versions 0.2c and 0.2d
876 ======================================
878 1. Dump is now able to backup 2GB+ filesystems.
880 2. Dump and restore can now be linked as static binaries.
882 Changes between versions 0.2b and 0.2c
883 ======================================
885 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
887 Changes between versions 0.2a and 0.2b
888 ======================================
890 1. Really fixed the bug that I should have corrected in 0.2a.
892 2. Enabled optimization again.
894 Changes between versions 0.2 and 0.2a
895 =====================================
897 1. Disabled the optimization during compilation.
899 Changes between versions 0.1 and 0.2
900 ====================================
902 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
903 the fs_type field (actually, I modified the file fstab.c to make it
904 use the mntent functions).
906 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
907 made by dump should be readable by the BSD restore and backups made
908 by the BSD dump should be readable by restore. Unfortunately, this
909 means that the dump format has changed between version 0.1 and version
912 3. Dump is now able to backup a subtree, it is no longer limited to whole
913 filesystems like the BSD version.
915 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
918 Changes between versions 0.0 and 0.1
919 ====================================
921 1. Now create links rdump and rrestore during the `make install' step.
923 2. Linux port specific bugs added to the manual pages
925 3. Incorrect estimation of the number of tapes blocks fixed when doing
928 4. Better ls-like format in restore in interactive mode.
