3 Changes between versions 0.4b24 and 0.4b25 (released ??????????????????)
4 ========================================================================
6 1. Added a mini howto from Patrick Walsh in the examples
9 2. Minor man pages syntax corrections. Thanks to
10 Chris Danis <screechco@home.com> for reporting the bugs.
12 3. Added a script from David B. Peterson <dave@toppledwagon.com>
13 to the examples section. It features dumping several
14 filesystems to a remote tape drive upon ssh.
16 4. Added a patch provided by Richard Jones <rich@annexia.org>
17 which allows BRADEMAX (number of read errors tolerated by
18 dump) to be adjusted using the -I option.
20 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
21 ========================================================================
23 1. Fixed the permissions of a newly created QFA file by dump.
25 2. Cleaned up the source of dump (the external variables
26 definition was a complete mess, making possible to have
29 3. Fixed restore to use the full tape volume path when doing
30 a compare (since it changes the working directory to the
31 filesystem being compared in the process).
33 4. Added the -q option to dump which makes dump abort
34 whenever it needs operator attention. It should be
35 easier to use dump in scripts with this option.
37 5. Detect the use of incompatible options to dump and
38 refuse them (like -a and -B options together).
40 6. Added bzip2 compression to dump/restore (use option -j level
41 to select it). Note that you will need a restore version
42 >= 0.4b24 in order to restore a bzip2 compressed dump.
43 The same warning as for the zlib compression applies:
44 the tape format of a bzip2 dump is not compatible with the
45 original BSD tape format.
47 7. Fixed a overflow problem in dump corrupting the dump when
48 very large files were encountered. Thanks to Vladimir Nadvornik
51 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
52 kernel buffer/page cache before starting the dump, helping
53 a bit those who use dump on mounted filesystems. Thanks to
54 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
57 9. Updated the RPM spec file following the RedHat changes
58 (dynamically linked binaries now in /usr/sbin etc).
60 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
61 which enables restore to recognise multi volume compressed dumps
62 done on CD. Included his scripts for dump (which pipe the dump
63 output directly into cdrecord) and restore. There is now
64 possible to to backups to CD on the fly!
66 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
67 ===================================================================
69 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
70 Marcus Meissner (Caldera International Security Dept.).
72 2. Implement the Sun rmt extended protocol. Patch submitted
73 by Ian Gordon <iangordon@users.sourceforge.net>.
75 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
76 the linux kernel header. This ensures that dump always has the
77 latest version of this file. Patch submitted by
78 Andreas Dilger <adilger@turbolinux.com>.
80 4. Report any filesystem present in either /etc/fstab with a
81 positive passno or /etc/dumpdates in dump -w output.
82 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
84 5. Fixed the looping problem in dump introduced in the
87 6. Changed the -B option of dump to limit the size of
88 _compressed_ output per volume if compression is on.
89 Patch contributed by Helmut Jarausch
90 <jarausch@igpm.rwth-aachen.de>. Note however that, since
91 it is impossible to predict the size of the compressed
92 data before doing the compression, the -B limit is a bit
95 7. Fixed a bug in reading the operator typed file/tape path for
96 the next volume in restore.
98 8. Implemented a "-F script" option to restore which permits the
99 user to specify a script which will be launched at the
100 beginning of each tape, useful for automatic programming of
101 tape changers for example. See the restore man page for the
102 script parameters and return codes.
104 9. Small fix for the QFA routines provided by Uwe Gohlke
105 <uwe@ugsoft.de>, and some recommendations for QFA uses in
108 10. Fixed the multivolume restoring where making a mistake
109 to the 'Mount next tape' prompt caused several blocks to
112 11. Enhanced the -e option of dump to take as a parameter a
113 comma separated list of inode numbers.
115 12. Added the -E option to dump which specify a file containing
116 inode numbers to exclude from the dump.
118 13. Fixed the compressed multi-volume dump + restore.
120 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
121 ==================================================================
123 1. Made dump report the number of blocks dumped per volume.
124 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
126 2. Fix a bug in dump where waiting too much at the 'change volumes'
127 question caused the volume to be rewritten. Thanks to
128 Graham Reed <greed@users.sourceforge.net> for reporting the
129 bug and providing a patch.
131 3. Added a compression option to dump, contributed by Jerry
132 Peters <gapeters@worldnet.att.net>.
134 WARNING: the compression works only on files/pipes and
135 drives supporting variable block size.
137 WARNING2: tapes created using the compression feature are
138 incompatible with the standard dump tape format, and a
139 version of restore >= 0.4b22 will be needed for extraction.
141 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
142 architectures. Thanks to Paul Slootman <paul@debian.org> for
143 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
146 5. Many cleanups (CPP defines, const char warnings, check of
147 ext2fs COMPAT flags, time_t cleanups, added libext2 version
148 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
150 6. Made --prefix option work in configure. All the install path
151 are now based on the configure parameters.
153 7. Added the Quick File Access mode in dump/restore, contributed
154 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
155 a file tape position for each inode, and this file is used by
156 restore (if called with parameter Q and the filename)
157 to directly position the tape at the file restore is currently
158 working on. This saves hours when restoring single files from
159 large backups, saves the tapes and the drive's head. Use
160 --enable-qfa option of configure to compile in the QFA support.
162 8. Added the possibility to dump several files and directories
163 in a single invocation of dump. Thanks to Uwe Gohlke
164 <uwe@ugsoft.de> for implementing this option.
166 9. Fixed the dumping and restoring of files with holes
167 (files ending with holes didn't get dumped or restored
170 10. Fixed a socket descriptor leak in dump, which leaved opened
171 3 file descriptors per dump process (and there is one dump
174 11. Fixed dump large file system support, by explicit use of
175 open64/lseek64/etc functions (explicit use needed because
176 e2fsprogs libraries don't behave well when compiled with
177 FILE_OFFSET_BITS=64).
179 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
180 ======================================================================
182 1. Fixed some bugs in the dump -w|-W logic introduced by
183 the previous version. Thanks to Andreas Dilger
184 <adilger@turbolinux.com> for his help on this one.
186 2. Fixed again a compilation problem when using old e2fs
187 headers (filesystem label related). Thanks to many users
188 who reported this stupid error.
190 3. Fixed a build problem on old lib5 based systems dealing with
191 _PATH_MNTTAB being undefined. Thanks to John Adams
192 <johna@onevista.com> for reporting the bug.
194 4. Improved the error detection in restore when creating
195 the temporary files in TMPDIR. Now restore will corectly
196 report a 'no space left on device' error instead of
197 strange errors which could imply an archive corruption.
198 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
199 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
201 5. Added the throughput information in dump's progression
202 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
205 6. Use libext2fs's inode scanning routines, which are particularly
206 robust when dealing with errors (especially when having some
207 bad blocks on the filesystem). Many thanks to Colin
208 <colin@horizon.com> for reporting the bug, investigating
209 the issues, finding a workaround, writing the patch and
210 fully testing it... (of course, if this patch will break
211 anything, he is to blame for :-)).
213 7. Made dump and restore LFS aware. Dump can dump a filesystem
214 containing large files, generate a large file on output and
215 restore can restore them. This feature is not enabled by
216 default, use --enable-largefile option of configure to enable
217 it (you need to have a LFS aware glibc though). Thanks to
218 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
219 and to Theodore T'so <tytso@valinux.com> for his always
222 8. Made dump ask upon a tape write error if it should rewrite
223 the current volume (assume this is a bad tape) or if it should
224 assume an end-of-tape condition (useful for tape drives which
225 behaves badly at the end of the tape). Thanks to Andreas
226 Dilger <adilger@turbolinux.com> for the suggestion.
228 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
229 =======================================================================
231 1. Fixed a small compilation problem due to a change
232 in the definintion of the struct sigaction in
233 glibc 2.0 / libc5. Thanks to Gunther Schlegel
234 <schlegel@riege.de> for reporting the bug and to
235 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
238 2. Modified the label and uuid analysis in order to be
239 self-contained (independant of kernel/libc headers). This
240 should fix the compile with older kernel/libc headers and
241 will preserve the functionality. Thanks to Bernhard Erdmann
242 <bernhard.erdmann@gmx.de> for reporting the bug.
244 3. The 'exclude inode' option, if applied to a directory
245 inode, excludes now correctly all the leaves of this
246 directory. Thanks to John R. Dennison
247 <gerdesas@users.sourceforge.net> for reporting the bug.
249 4. Fixed the '-e' option to disable the possibility
250 to exclude the root inode (which causes the dumps to
251 be unreadable by restore). Prevented array overflow
252 when multiple -e options are used.
254 5. Fixed dump to correctly interpret a filesystem argument
255 which is a mountpoint and it is not an absolute path
256 (as specified in the fstab). Thanks to Bernhard R. Erdmann
257 <be@berdmann.de> for reporting the bug.
259 6. Made dump able to backup files larger than 2 GB. Note that
260 dump still doesn't cope with files larger than 4 GB.
262 7. Restore the real uid and gid before invoking an external
263 RSH program (big hole when dump or restore is suid root!).
265 8. Get the values for the default tape device and the location
266 of fstab file from the system headers. Thanks to
267 Andreas Dilger <adilger@turbolinux.com> for the patch.
269 9. Made dump -w|-W report all recognized filesystems
270 present in either /etc/fstab or /etc/dumpdates, and present
271 the list in the same order as in fstab file. Thanks
272 to Andreas Dilger <adilger@turbolinux.com> for the patch.
274 10. Made dump's -a (automatic end of tape detection) the
275 default. Specifying one of -B, -c, -d or -s options will
276 override the EOM detection. Thanks to Andreas Dilger
277 <adilger@turbolinux.com> for the patch.
279 11. Save the ext2 filesystem label into the dump volume label.
280 Specifying a volume label on the command line (-L option)
281 will override this feature. Thanks to Andreas Dilger
282 <adilger@turbolinux.com> for the patch.
284 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
285 =====================================================================
287 1. Fixed the signal handling in dump (which I broke in 0.4b17)
288 which was causing several strange dump failures (dump
289 hanged or segmentation faults etc).
291 2. Specified the default blocksize in the dump man page.
293 3. Changed two info messages of restore to be written on stdout
294 instead of stderr in order to leave stderr only for errors
295 or warnings. Thanks to Stephen Atwell
296 <satwell@urbana.css.mot.com> for the suggestion.
298 4. Corrected an off by one calculation which prevented
299 dumping a directory having a 1 character name length.
300 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
301 for reporting the bug.
303 5. Reinforce dump in order to allow only level 0 and no
304 -u option when dumping a subdirectory, and document
305 this in the man page. Thanks to Bernhard Erdmann
306 <bernhard.erdmann@gmx.de> for reporting the bug.
308 6. Fixed a small harmless bug in restore which caused
309 in some conditions hard links to be restored several
310 times (therefore generation some warning messages).
311 Thanks to Kenneth Porter <shiva@well.com> for
314 7. Updated the RPM spec file to the latest RedHat version,
315 providing FHS packaging and other cosmetic changes.
316 You will need RPM version >= 3.0.5 in order to build the RPM.
318 8. Updated the configure script to check for libtermcap
319 before checking for libreadline, because we need this
320 library in order to compile the readline support.
322 9. Made dump understand the LABEL= and UUID= notation
323 both in /etc/fstab and on the command line. Note that
324 you will need the /proc filesystem in order to use
325 these notations. Thanks to Erik Troan <ewt@redhat.com>
326 for providing the patch.
328 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
329 ===================================================================
331 1. Fixed a potential buffer overflow in restore. Thanks
332 to Stan Bubrouski <satan@fastdial.net> for reporting
335 2. Fixed a readline-related bug which prevented
336 'cat DUMPFILE | restore -i -f -' from working. Thanks
337 to Charles Karney <karney@users.sourceforge.net>
340 3. Changed a few "panic" into "exit", causing restore to
341 be more stable against some attacks (like the last one
342 reported on Bugtraq, although the last version of restore
343 was not vulnerable - just dumped core). Thanks to
344 Andreas Hasenack <andreas@conectiva.com.br> for reporting
347 4. Removed the suid-root bit on dump and restore in the
348 default build (and generated RPMs). It should be safer
349 now. Users who need the suid-root capabilities in order
350 to make network backups should read first the man page
351 of dump and enable the suid bit manually.
353 5. Added -ltermcap to the compile parameters for restore
354 when using readline support, in order to make the compile
355 process work on some systems (SuSE ?). Thanks to
356 Patrik Schindler <poc@pocnet.net> for reporting the bug.
358 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
359 ====================================================================
361 1. The -F script is called now *only* at the end of a tape,
362 not at the end of the dump. Thanks to Christian Haul
363 <haul@informatik.tu-darmstadt.de> for the bug report.
365 Normally, the device name and the current volume number
366 are passed on the command line of the script. However,
367 if you want the old style script (with no arguments
368 passed on the command line), you can enable it in
369 configure with the --enable-oldstylefscript.
371 2. Use posix signal handling to preserve dump functionality
372 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
375 3. Made the exit code of restore in case of a 'C'ompare
376 command reflect the result of the compare. An exit status
377 of 0 means the dump archive is correct, 1 means tape errors,
378 2 means that some files were modified. Thanks to Kenneth Porter
379 <shiva@well.com> for the suggestion.
381 4. Made (finally) quotes work in interactive restore.
383 5. Small fixes in order to allow dump to compile with a
384 really old e2fsprogs version. Thanks to Ian Zimmerman
385 <itz@speakeasy.org> for the bug report.
387 6. Add GNU readline capabilities to interactive restore.
388 Use configure's --enable-readline flag to enable this feature.
389 Thanks to Patrik Schindler <poc@pocnet.net> for the
392 7. Do the compare on the fly in restore 'C' mode (this will
393 allow not to exhaust the available /tmp space when
394 ccmparing large files). Thanks to Kenneth Porter
395 <shiva@well.com> for the suggestion.
397 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
398 ====================================================================
400 1. Fixed some several duplicate 'DUMP: DUMP:' in the
403 2. Corrected the estimation of blocks to dump. Note that
404 this is still wrong for large directory inodes, due
405 to the size of a BSD directory entry on the tape
406 (estimation is based on the size of the ext2 directory,
407 which is smaller because it doesn't contain the null
408 character at the end).
410 3. Made dump report the total number of MB written to
411 tape at the end of run. Thanks to W. Reilly Cooley
412 <wcooley@nakedape.cc> for the patch.
414 4. Added the -X option to restore giving the possibility
415 to read the names of the files to be extracted/listed
416 from a text file (in addition of the command line).
417 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
420 5. Added the device name and the current volume number
421 as arguments to the end of tape script (dump -F option).
423 6. Made the multi-volume dump work again (after having
424 broken it in 0.4b15).
426 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
427 ===================================================================
429 1. Added a prompt command in interactive restore mode. Thanks
430 to Andreas Dilger <adilger@home.com> for the patch.
432 2. Fixed a buffer overflow problem in dump (caused by
433 not checking the size of the filesystem parameter).
434 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
435 reporting this on Bugtraq (and to several dump users
436 who forwarded me his mail).
438 3. Added the '-F script' option to dump in order to
439 launch a script at the end of each tape (to be used
440 with a tape changer, or to notify the sysadmin by
443 4. Fixed a bug in restore compare code caused by the changes
446 5. Fixed the treatment of options using the old BSD syntax
447 in both dump and restore.
449 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
450 =======================================================================
452 1. Fixed a bug in dump which may have caused invalid deleted
453 directories to be dumped out if they were deleted after the
454 mapping pass. This could occure on active filesystem and lead
455 to heap corruption (causing dump malfunction in many possible ways).
456 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
457 bug and submitting the patch.
459 2. Fixed the handling of the filesystem parameter in dump. A
460 '/mnt/disk' parameter caused the disk contents to be dumped,
461 but a '/mnt/disk/' parameter caused the mountpoint directory
462 to be dumped (generally an empty directory).
464 3. Improved the output of dump in order to tell which directory
465 it is currently dumping (when dumping a subtree).
467 4. Added the '-e' exclude inode option to dump. Thanks to
468 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
470 5. Added a REPORTING-BUGS file in order to provide a guide
471 on how to correctly report a bug in dump/restore.
473 6. Fixed a restore problem when restoring a hard link to an inode
474 having the immutable or append-only attribute set. Thanks to
475 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
477 7. Fixed a compatibility problem between dumps made on little
478 endian machines (the format was correct) and big endian
479 machines (the format was incorrect). This fix break the
480 compatibility with the older dumps made on big endian
481 machines (sparc, m86k, ppc etc). For the first time in
482 linux dump's history (I believe), the dumps made by *BSD,
483 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
484 so interchangeable. Thanks to Rob Cermak
485 <cermak@ahab.rutgers.edu> for submitting the bug and
486 helping me test the fix.
488 8. Fixed the way dump reports the remaining percent/time, if
489 the number of blocks actually dumped exceeds the estimated
490 number of blocks. Thanks to Jean-Paul van der Jagt
491 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
493 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
494 ======================================================================
496 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
497 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
499 2. Removed the requirement to build the RPM as root from the
500 spec file. Thanks to Christian Weisgerber
501 <naddy@mips.rhein-neckar.de> for submitting this.
503 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
504 causing dump to block when dumping really huge filesystems.
505 Many thanks to Patrik Schindler <poc@pocnet.net> for
506 helping me find this bug.
508 4. Fixed the treatment for an interrupt signal when dump access
509 the remote tape through RSH. Thanks to Christian Weisgerber
510 <naddy@mips.rhein-neckar.de> for providing the patch.
512 5. Fixed a bug which was causing dump/restore to display
513 garbage characters instead of the remote host name.
515 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
516 =====================================================================
518 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
519 <kukuk@suse.de> for submitting the patch.
521 2. Fix for the exit code when using the size estimate option of
522 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
523 submitting the patch.
525 3. Handle EINTR in atomical reads/writes in dump, which was causing
526 dump to fail on some systems. Thanks to Eric Jergensen
527 <eric@dvns.com> for reporting the bug and submitting the patch.
529 4. Handle more than 16 characters for the device names in dumpdates.
530 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
531 tracking down the problem and proposing the solution.
533 5. Fixed a bug in dump which prevented the creation of the
534 dumpdates file when doing a 0-level dump without already
535 having a dumpdates file. Thanks to Patrik Schindler
536 <poc@pocnet.net> for reporting the bug.
538 6. Changed the way dump 'S' flag reports the size estimate
539 from number of blocks into bytes (making it compatible
540 with the Solaris version, and simplifying things for
541 amanda users). Thanks to Jason L Tibbitts III
542 <tibbs@math.uh.edu> for reporting the bug.
544 7. Fixed a compatibility problem in linux/alpha dump tape format.
545 Now the linux/alpha dump are (again) compatible with the
546 other dump formats. But this breaks compatibility with
547 older dumps made on alpha. Thanks to Mike Tibor
548 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
550 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
551 ======================================================================
553 1. Added a '--enable-kerberos' to configure.
555 2. Added a 'S' option to dump which determines the amount of space
556 that is needed to perform the dump without actually doing it, similar
557 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
558 <cermak@ahab.rutgers.edu>.
560 3. Added a 'M' multi-volume option to dump and restore which enables
561 dumping to multiple files (useful when dumping to an ext2
562 partition to make several dump files in order to bypass the 2GB
563 file size limitation). The 'f' argument is treated as a prefix and
564 the output files will be named <prefix>001, <prefix>002 etc. With
565 the 'M' flag, restore automatically selects the right file without
566 asking to enter a new tape each time.
568 4. Fixed a memory leak which was causing dump to grow very big
569 (270MB when dumping a 10GB filesystem...). Thanks to Jason
570 Fearon <jasonf@netrider.org.au> for reporting the bug.
572 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
573 ======================================================================
575 1. Make configure test if the system glob routines support
576 extended syntax (ALTDIRFUNC). If not, use the internal glob
577 routines instead of system ones. Thanks to Bernhard Sadlowski
578 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
579 and helping me resolve this and other minor libc5 compiling
582 2. Fix a problem when dumping a ext2fs with the 'filetype'
583 feature enabled. Thanks to Patrick J. LoPresti
584 <patl@cag.lcs.mit.edu> for reporting the bug and to
585 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
587 3. Made the nodump flag work on directories. A directory which
588 has the nodump flag gets never dumped, regardless of its
591 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
592 which allows dump on an active ext3 filesystem. However, this
593 is a "quick and dirty" patch which enables backup of an ext3
594 filesystem through the ext2 compatibility (by ignoring the
595 NEEDS_RECOVERY bit). The journal file is not recognized and
596 it is dumped (it should not).
598 5. Test the superblock compatibility flags when dumping, in order
599 to be sure that we know how to deal with specific features.
601 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
602 ====================================================================
604 1. Use lchown instead of chown, fixing a possible security problem
605 when restoring symlinks (a malicious user could use this
606 to deliberately corrupt the ownership of important system files).
607 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
608 this and providing the patch.
610 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
611 ====================================================================
613 1. Put dump sources under CVS, added Id tags in all files so
614 one can use 'ident' on binary files.
616 2. Added the dump/restore version in the usage text so one can
617 easily verify the version he is using.
619 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
620 a va_start/va_end problem on linux-ppc (always call va_start
621 va_end in pairs each time we use a vararg function).
623 4. Added again the DT_* constants because old libc does not
624 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
625 for submitting the bug report.
627 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
628 this should enable dumping big (huge) filesystems.
630 6. Added the RSH environment variable in order to be able to
631 use a rsh replacement like ssh when doing remote backups (and
632 bypass the security limitations of rcmd). Now you can do remote
633 backups without being root (or making dump setuid root).
635 7. Modified again the way dumpdates works. For incremental dumps,
636 we need to read dumpdates even if we are not using 'u' option.
637 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
640 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
641 ===================================================================
643 1. Removed the 'k' flag from the restore 'about' text if kerberos
646 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
647 to them (fsetflags takes a char*, setflags an open fd!).
649 3. (f)setflags is called only if the flags aren't empty. If the
650 file is a special file, a warning is printed, because changing
651 flags implies opening the device. Normally, a special file
652 should not have any flag... (Debian bug #29775, patch provided
653 by Abhijit Dasgupta <abhijit@ans.net>).
655 4. Made possible to dump a file system not mentioned in /etc/fstab.
656 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
658 5. Changed the default behaviour to not create dumpdates
659 unless 'u' option is specified. Removed the old "debian-patch"
660 which provided the same thing. (Debian bug #38136, #33818).
662 6. Removed all those dump*announce, since they were getting old...
664 7. Added warning messages if dumpdates does not exist and
665 when an inferior level dump does not exist (except for a level 0
668 8. Debugged the glob calls in interactive mode: restore used a
669 dirent struct which was different from the /usr/include/dirent.h
670 one (this used to work, is it a glibc2 change?), so none of the
671 compat glob (which used /usr/include/dirent.h) or the system glob
672 worked. Restore use now the system dirent (and the system
673 DT_* constants), which are compatible with BSD ones.
675 9. Added a configure flag (--with-dumpdatespath) to specify
676 the location of dumpdates file. By default, it is
679 10. Added the "AUTHOR" and "AVAILABILITY" sections and
680 included the current date/version in man pages.
682 11. Corrected the estimation of remaining time when
683 the operator doesn't change the tapes quickly enough. This
684 was an old bug, I thought I corrected it, and discovered
685 that in fact it was corrected in two different places, so
686 the results canceled each other...
688 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
689 ===================================================================
691 1. Integrated multiple patches from RedHat, Debian and SuSE:
693 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
695 - several fixes in the man pages.
696 - update the default tape device to /dev/st0.
697 - many updates for Linux Alpha (byte ordering, size_t etc).
699 - use environment variable for TMPDIR (instead of /tmp).
700 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
701 - workaround egcs bug (RedHat bugs #4281 and #2989).
702 - wire $(OPT) throughout Makefile's.
704 2. Upgrade the dump revision to 1, making possible to dump filesystems
705 made with e2fsprogs-1.15 or newer. Nothing seems to break...
707 3. Fix some compile warnings, prototype all functions.
709 4. Use glibc err/glob instead of internal compatibility
710 routines (only if available).
712 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
713 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
715 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
716 ======================================================================
718 1. Integrated the changes from FreeBSD-3.1-RELEASE
719 (mostly bug fixes, buffer overruns, dump has now an "automatic
720 tape length calculation" flag, dump/restore can use kerberos now
721 (this is NOT tested), use environment variables for TAPE and
724 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
726 3. Corrected a bug in restore when using 'C' option with multi-volumes
727 tapes (files splited accros two tapes give "size changed" errors
730 4. Corrected the long standing bug when dumping multiple tapes.
731 This works for me, needs further testing.
733 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
734 ====================================================================
736 1. Dump now runs correctly on kernels 2.1.x
737 Fix made by Gerald Peters <gapeters@worldnet.att.net>
739 Changes between versions 0.4b2 and 0.4b3
740 ========================================
742 1. Use realpath() if available
746 Changes between versions 0.4b1 and 0.4b2
747 ========================================
749 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
752 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
754 3. Fixed configure.in to correctly handle --enable-rmt
756 Changes between versions 0.3 and 0.4b1
757 ======================================
759 1. Integrated the changes from 4.4BSD-Lite2
761 2. Integrated the patches from Debian and Red Hat
763 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
765 4. Changed dump to use the Ext2fs library to get block addresses. This
766 should solve the endianness problem on SparcLinux.
768 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
769 distribution's one) to use autoconf
771 6. Fixed a few minor bugs
773 Changes between versions 0.2e and 0.2f
774 ======================================
776 1. Added the creation of named pipes (fifos) in restore.
778 2. Added the -N flag in the restore manual page.
780 3. Added the file kernel.patch which contains the llseek() optimization
781 patch for 1.2.x kernels.
783 4. Fixed a bug in the restoration of symbolic links: owner and group were
786 5. Integrated some changes from FreeBSD 2.2.
788 6. Added a call to ftruncate() after restoring each file to restore
789 correctly files ending by a hole.
791 Changes between versions 0.2d and 0.2e
792 ======================================
794 1. Fixed a bug in the "set owner/mode" process. Every file was restored
795 with owner = root (0) and group = root/wheel/whatever (0).
797 Changes between versions 0.2c and 0.2d
798 ======================================
800 1. Dump is now able to backup 2GB+ filesystems.
802 2. Dump and restore can now be linked as static binaries.
804 Changes between versions 0.2b and 0.2c
805 ======================================
807 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
809 Changes between versions 0.2a and 0.2b
810 ======================================
812 1. Really fixed the bug that I should have corrected in 0.2a.
814 2. Enabled optimization again.
816 Changes between versions 0.2 and 0.2a
817 =====================================
819 1. Disabled the optimization during compilation.
821 Changes between versions 0.1 and 0.2
822 ====================================
824 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
825 the fs_type field (actually, I modified the file fstab.c to make it
826 use the mntent functions).
828 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
829 made by dump should be readable by the BSD restore and backups made
830 by the BSD dump should be readable by restore. Unfortunately, this
831 means that the dump format has changed between version 0.1 and version
834 3. Dump is now able to backup a subtree, it is no longer limited to whole
835 filesystems like the BSD version.
837 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
840 Changes between versions 0.0 and 0.1
841 ====================================
843 1. Now create links rdump and rrestore during the `make install' step.
845 2. Linux port specific bugs added to the manual pages
847 3. Incorrect estimation of the number of tapes blocks fixed when doing
850 4. Better ls-like format in restore in interactive mode.
