3 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
4 ========================================================================
6 1. Fixed the permissions of a newly created QFA file by dump.
8 2. Cleaned up the source of dump (the external variables
9 definition was a complete mess, making possible to have
12 3. Fixed restore to use the full tape volume path when doing
13 a compare (since it changes the working directory to the
14 filesystem being compared in the process).
16 4. Added the -q option to dump which makes dump abort
17 whenever it needs operator attention. It should be
18 easier to use dump in scripts with this option.
20 5. Detect the use of incompatible options to dump and
21 refuse them (like -a and -B options together).
23 6. Added bzip2 compression to dump/restore (use option -j level
24 to select it). Note that you will need a restore version
25 >= 0.4b24 in order to restore a bzip2 compressed dump.
26 The same warning as for the zlib compression applies:
27 the tape format of a bzip2 dump is not compatible with the
28 original BSD tape format.
30 7. Fixed a overflow problem in dump corrupting the dump when
31 very large files were encountered. Thanks to Vladimir Nadvornik
34 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
35 kernel buffer/page cache before starting the dump, helping
36 a bit those who use dump on mounted filesystems. Thanks to
37 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
40 9. Updated the RPM spec file following the RedHat changes
41 (dynamically linked binaries now in /usr/sbin etc).
43 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
44 which enables restore to recognise multi volume compressed dumps
45 done on CD. Included his scripts for dump (which pipe the dump
46 output directly into cdrecord) and restore. There is now
47 possible to to backups to CD on the fly!
49 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
50 ===================================================================
52 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
53 Marcus Meissner (Caldera International Security Dept.).
55 2. Implement the Sun rmt extended protocol. Patch submitted
56 by Ian Gordon <iangordon@users.sourceforge.net>.
58 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
59 the linux kernel header. This ensures that dump always has the
60 latest version of this file. Patch submitted by
61 Andreas Dilger <adilger@turbolinux.com>.
63 4. Report any filesystem present in either /etc/fstab with a
64 positive passno or /etc/dumpdates in dump -w output.
65 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
67 5. Fixed the looping problem in dump introduced in the
70 6. Changed the -B option of dump to limit the size of
71 _compressed_ output per volume if compression is on.
72 Patch contributed by Helmut Jarausch
73 <jarausch@igpm.rwth-aachen.de>. Note however that, since
74 it is impossible to predict the size of the compressed
75 data before doing the compression, the -B limit is a bit
78 7. Fixed a bug in reading the operator typed file/tape path for
79 the next volume in restore.
81 8. Implemented a "-F script" option to restore which permits the
82 user to specify a script which will be launched at the
83 beginning of each tape, useful for automatic programming of
84 tape changers for example. See the restore man page for the
85 script parameters and return codes.
87 9. Small fix for the QFA routines provided by Uwe Gohlke
88 <uwe@ugsoft.de>, and some recommendations for QFA uses in
91 10. Fixed the multivolume restoring where making a mistake
92 to the 'Mount next tape' prompt caused several blocks to
95 11. Enhanced the -e option of dump to take as a parameter a
96 comma separated list of inode numbers.
98 12. Added the -E option to dump which specify a file containing
99 inode numbers to exclude from the dump.
101 13. Fixed the compressed multi-volume dump + restore.
103 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
104 ==================================================================
106 1. Made dump report the number of blocks dumped per volume.
107 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
109 2. Fix a bug in dump where waiting too much at the 'change volumes'
110 question caused the volume to be rewritten. Thanks to
111 Graham Reed <greed@users.sourceforge.net> for reporting the
112 bug and providing a patch.
114 3. Added a compression option to dump, contributed by Jerry
115 Peters <gapeters@worldnet.att.net>.
117 WARNING: the compression works only on files/pipes and
118 drives supporting variable block size.
120 WARNING2: tapes created using the compression feature are
121 incompatible with the standard dump tape format, and a
122 version of restore >= 0.4b22 will be needed for extraction.
124 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
125 architectures. Thanks to Paul Slootman <paul@debian.org> for
126 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
129 5. Many cleanups (CPP defines, const char warnings, check of
130 ext2fs COMPAT flags, time_t cleanups, added libext2 version
131 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
133 6. Made --prefix option work in configure. All the install path
134 are now based on the configure parameters.
136 7. Added the Quick File Access mode in dump/restore, contributed
137 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
138 a file tape position for each inode, and this file is used by
139 restore (if called with parameter Q and the filename)
140 to directly position the tape at the file restore is currently
141 working on. This saves hours when restoring single files from
142 large backups, saves the tapes and the drive's head. Use
143 --enable-qfa option of configure to compile in the QFA support.
145 8. Added the possibility to dump several files and directories
146 in a single invocation of dump. Thanks to Uwe Gohlke
147 <uwe@ugsoft.de> for implementing this option.
149 9. Fixed the dumping and restoring of files with holes
150 (files ending with holes didn't get dumped or restored
153 10. Fixed a socket descriptor leak in dump, which leaved opened
154 3 file descriptors per dump process (and there is one dump
157 11. Fixed dump large file system support, by explicit use of
158 open64/lseek64/etc functions (explicit use needed because
159 e2fsprogs libraries don't behave well when compiled with
160 FILE_OFFSET_BITS=64).
162 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
163 ======================================================================
165 1. Fixed some bugs in the dump -w|-W logic introduced by
166 the previous version. Thanks to Andreas Dilger
167 <adilger@turbolinux.com> for his help on this one.
169 2. Fixed again a compilation problem when using old e2fs
170 headers (filesystem label related). Thanks to many users
171 who reported this stupid error.
173 3. Fixed a build problem on old lib5 based systems dealing with
174 _PATH_MNTTAB being undefined. Thanks to John Adams
175 <johna@onevista.com> for reporting the bug.
177 4. Improved the error detection in restore when creating
178 the temporary files in TMPDIR. Now restore will corectly
179 report a 'no space left on device' error instead of
180 strange errors which could imply an archive corruption.
181 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
182 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
184 5. Added the throughput information in dump's progression
185 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
188 6. Use libext2fs's inode scanning routines, which are particularly
189 robust when dealing with errors (especially when having some
190 bad blocks on the filesystem). Many thanks to Colin
191 <colin@horizon.com> for reporting the bug, investigating
192 the issues, finding a workaround, writing the patch and
193 fully testing it... (of course, if this patch will break
194 anything, he is to blame for :-)).
196 7. Made dump and restore LFS aware. Dump can dump a filesystem
197 containing large files, generate a large file on output and
198 restore can restore them. This feature is not enabled by
199 default, use --enable-largefile option of configure to enable
200 it (you need to have a LFS aware glibc though). Thanks to
201 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
202 and to Theodore T'so <tytso@valinux.com> for his always
205 8. Made dump ask upon a tape write error if it should rewrite
206 the current volume (assume this is a bad tape) or if it should
207 assume an end-of-tape condition (useful for tape drives which
208 behaves badly at the end of the tape). Thanks to Andreas
209 Dilger <adilger@turbolinux.com> for the suggestion.
211 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
212 =======================================================================
214 1. Fixed a small compilation problem due to a change
215 in the definintion of the struct sigaction in
216 glibc 2.0 / libc5. Thanks to Gunther Schlegel
217 <schlegel@riege.de> for reporting the bug and to
218 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
221 2. Modified the label and uuid analysis in order to be
222 self-contained (independant of kernel/libc headers). This
223 should fix the compile with older kernel/libc headers and
224 will preserve the functionality. Thanks to Bernhard Erdmann
225 <bernhard.erdmann@gmx.de> for reporting the bug.
227 3. The 'exclude inode' option, if applied to a directory
228 inode, excludes now correctly all the leaves of this
229 directory. Thanks to John R. Dennison
230 <gerdesas@users.sourceforge.net> for reporting the bug.
232 4. Fixed the '-e' option to disable the possibility
233 to exclude the root inode (which causes the dumps to
234 be unreadable by restore). Prevented array overflow
235 when multiple -e options are used.
237 5. Fixed dump to correctly interpret a filesystem argument
238 which is a mountpoint and it is not an absolute path
239 (as specified in the fstab). Thanks to Bernhard R. Erdmann
240 <be@berdmann.de> for reporting the bug.
242 6. Made dump able to backup files larger than 2 GB. Note that
243 dump still doesn't cope with files larger than 4 GB.
245 7. Restore the real uid and gid before invoking an external
246 RSH program (big hole when dump or restore is suid root!).
248 8. Get the values for the default tape device and the location
249 of fstab file from the system headers. Thanks to
250 Andreas Dilger <adilger@turbolinux.com> for the patch.
252 9. Made dump -w|-W report all recognized filesystems
253 present in either /etc/fstab or /etc/dumpdates, and present
254 the list in the same order as in fstab file. Thanks
255 to Andreas Dilger <adilger@turbolinux.com> for the patch.
257 10. Made dump's -a (automatic end of tape detection) the
258 default. Specifying one of -B, -c, -d or -s options will
259 override the EOM detection. Thanks to Andreas Dilger
260 <adilger@turbolinux.com> for the patch.
262 11. Save the ext2 filesystem label into the dump volume label.
263 Specifying a volume label on the command line (-L option)
264 will override this feature. Thanks to Andreas Dilger
265 <adilger@turbolinux.com> for the patch.
267 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
268 =====================================================================
270 1. Fixed the signal handling in dump (which I broke in 0.4b17)
271 which was causing several strange dump failures (dump
272 hanged or segmentation faults etc).
274 2. Specified the default blocksize in the dump man page.
276 3. Changed two info messages of restore to be written on stdout
277 instead of stderr in order to leave stderr only for errors
278 or warnings. Thanks to Stephen Atwell
279 <satwell@urbana.css.mot.com> for the suggestion.
281 4. Corrected an off by one calculation which prevented
282 dumping a directory having a 1 character name length.
283 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
284 for reporting the bug.
286 5. Reinforce dump in order to allow only level 0 and no
287 -u option when dumping a subdirectory, and document
288 this in the man page. Thanks to Bernhard Erdmann
289 <bernhard.erdmann@gmx.de> for reporting the bug.
291 6. Fixed a small harmless bug in restore which caused
292 in some conditions hard links to be restored several
293 times (therefore generation some warning messages).
294 Thanks to Kenneth Porter <shiva@well.com> for
297 7. Updated the RPM spec file to the latest RedHat version,
298 providing FHS packaging and other cosmetic changes.
299 You will need RPM version >= 3.0.5 in order to build the RPM.
301 8. Updated the configure script to check for libtermcap
302 before checking for libreadline, because we need this
303 library in order to compile the readline support.
305 9. Made dump understand the LABEL= and UUID= notation
306 both in /etc/fstab and on the command line. Note that
307 you will need the /proc filesystem in order to use
308 these notations. Thanks to Erik Troan <ewt@redhat.com>
309 for providing the patch.
311 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
312 ===================================================================
314 1. Fixed a potential buffer overflow in restore. Thanks
315 to Stan Bubrouski <satan@fastdial.net> for reporting
318 2. Fixed a readline-related bug which prevented
319 'cat DUMPFILE | restore -i -f -' from working. Thanks
320 to Charles Karney <karney@users.sourceforge.net>
323 3. Changed a few "panic" into "exit", causing restore to
324 be more stable against some attacks (like the last one
325 reported on Bugtraq, although the last version of restore
326 was not vulnerable - just dumped core). Thanks to
327 Andreas Hasenack <andreas@conectiva.com.br> for reporting
330 4. Removed the suid-root bit on dump and restore in the
331 default build (and generated RPMs). It should be safer
332 now. Users who need the suid-root capabilities in order
333 to make network backups should read first the man page
334 of dump and enable the suid bit manually.
336 5. Added -ltermcap to the compile parameters for restore
337 when using readline support, in order to make the compile
338 process work on some systems (SuSE ?). Thanks to
339 Patrik Schindler <poc@pocnet.net> for reporting the bug.
341 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
342 ====================================================================
344 1. The -F script is called now *only* at the end of a tape,
345 not at the end of the dump. Thanks to Christian Haul
346 <haul@informatik.tu-darmstadt.de> for the bug report.
348 Normally, the device name and the current volume number
349 are passed on the command line of the script. However,
350 if you want the old style script (with no arguments
351 passed on the command line), you can enable it in
352 configure with the --enable-oldstylefscript.
354 2. Use posix signal handling to preserve dump functionality
355 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
358 3. Made the exit code of restore in case of a 'C'ompare
359 command reflect the result of the compare. An exit status
360 of 0 means the dump archive is correct, 1 means tape errors,
361 2 means that some files were modified. Thanks to Kenneth Porter
362 <shiva@well.com> for the suggestion.
364 4. Made (finally) quotes work in interactive restore.
366 5. Small fixes in order to allow dump to compile with a
367 really old e2fsprogs version. Thanks to Ian Zimmerman
368 <itz@speakeasy.org> for the bug report.
370 6. Add GNU readline capabilities to interactive restore.
371 Use configure's --enable-readline flag to enable this feature.
372 Thanks to Patrik Schindler <poc@pocnet.net> for the
375 7. Do the compare on the fly in restore 'C' mode (this will
376 allow not to exhaust the available /tmp space when
377 ccmparing large files). Thanks to Kenneth Porter
378 <shiva@well.com> for the suggestion.
380 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
381 ====================================================================
383 1. Fixed some several duplicate 'DUMP: DUMP:' in the
386 2. Corrected the estimation of blocks to dump. Note that
387 this is still wrong for large directory inodes, due
388 to the size of a BSD directory entry on the tape
389 (estimation is based on the size of the ext2 directory,
390 which is smaller because it doesn't contain the null
391 character at the end).
393 3. Made dump report the total number of MB written to
394 tape at the end of run. Thanks to W. Reilly Cooley
395 <wcooley@nakedape.cc> for the patch.
397 4. Added the -X option to restore giving the possibility
398 to read the names of the files to be extracted/listed
399 from a text file (in addition of the command line).
400 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
403 5. Added the device name and the current volume number
404 as arguments to the end of tape script (dump -F option).
406 6. Made the multi-volume dump work again (after having
407 broken it in 0.4b15).
409 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
410 ===================================================================
412 1. Added a prompt command in interactive restore mode. Thanks
413 to Andreas Dilger <adilger@home.com> for the patch.
415 2. Fixed a buffer overflow problem in dump (caused by
416 not checking the size of the filesystem parameter).
417 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
418 reporting this on Bugtraq (and to several dump users
419 who forwarded me his mail).
421 3. Added the '-F script' option to dump in order to
422 launch a script at the end of each tape (to be used
423 with a tape changer, or to notify the sysadmin by
426 4. Fixed a bug in restore compare code caused by the changes
429 5. Fixed the treatment of options using the old BSD syntax
430 in both dump and restore.
432 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
433 =======================================================================
435 1. Fixed a bug in dump which may have caused invalid deleted
436 directories to be dumped out if they were deleted after the
437 mapping pass. This could occure on active filesystem and lead
438 to heap corruption (causing dump malfunction in many possible ways).
439 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
440 bug and submitting the patch.
442 2. Fixed the handling of the filesystem parameter in dump. A
443 '/mnt/disk' parameter caused the disk contents to be dumped,
444 but a '/mnt/disk/' parameter caused the mountpoint directory
445 to be dumped (generally an empty directory).
447 3. Improved the output of dump in order to tell which directory
448 it is currently dumping (when dumping a subtree).
450 4. Added the '-e' exclude inode option to dump. Thanks to
451 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
453 5. Added a REPORTING-BUGS file in order to provide a guide
454 on how to correctly report a bug in dump/restore.
456 6. Fixed a restore problem when restoring a hard link to an inode
457 having the immutable or append-only attribute set. Thanks to
458 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
460 7. Fixed a compatibility problem between dumps made on little
461 endian machines (the format was correct) and big endian
462 machines (the format was incorrect). This fix break the
463 compatibility with the older dumps made on big endian
464 machines (sparc, m86k, ppc etc). For the first time in
465 linux dump's history (I believe), the dumps made by *BSD,
466 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
467 so interchangeable. Thanks to Rob Cermak
468 <cermak@ahab.rutgers.edu> for submitting the bug and
469 helping me test the fix.
471 8. Fixed the way dump reports the remaining percent/time, if
472 the number of blocks actually dumped exceeds the estimated
473 number of blocks. Thanks to Jean-Paul van der Jagt
474 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
476 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
477 ======================================================================
479 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
480 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
482 2. Removed the requirement to build the RPM as root from the
483 spec file. Thanks to Christian Weisgerber
484 <naddy@mips.rhein-neckar.de> for submitting this.
486 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
487 causing dump to block when dumping really huge filesystems.
488 Many thanks to Patrik Schindler <poc@pocnet.net> for
489 helping me find this bug.
491 4. Fixed the treatment for an interrupt signal when dump access
492 the remote tape through RSH. Thanks to Christian Weisgerber
493 <naddy@mips.rhein-neckar.de> for providing the patch.
495 5. Fixed a bug which was causing dump/restore to display
496 garbage characters instead of the remote host name.
498 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
499 =====================================================================
501 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
502 <kukuk@suse.de> for submitting the patch.
504 2. Fix for the exit code when using the size estimate option of
505 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
506 submitting the patch.
508 3. Handle EINTR in atomical reads/writes in dump, which was causing
509 dump to fail on some systems. Thanks to Eric Jergensen
510 <eric@dvns.com> for reporting the bug and submitting the patch.
512 4. Handle more than 16 characters for the device names in dumpdates.
513 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
514 tracking down the problem and proposing the solution.
516 5. Fixed a bug in dump which prevented the creation of the
517 dumpdates file when doing a 0-level dump without already
518 having a dumpdates file. Thanks to Patrik Schindler
519 <poc@pocnet.net> for reporting the bug.
521 6. Changed the way dump 'S' flag reports the size estimate
522 from number of blocks into bytes (making it compatible
523 with the Solaris version, and simplifying things for
524 amanda users). Thanks to Jason L Tibbitts III
525 <tibbs@math.uh.edu> for reporting the bug.
527 7. Fixed a compatibility problem in linux/alpha dump tape format.
528 Now the linux/alpha dump are (again) compatible with the
529 other dump formats. But this breaks compatibility with
530 older dumps made on alpha. Thanks to Mike Tibor
531 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
533 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
534 ======================================================================
536 1. Added a '--enable-kerberos' to configure.
538 2. Added a 'S' option to dump which determines the amount of space
539 that is needed to perform the dump without actually doing it, similar
540 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
541 <cermak@ahab.rutgers.edu>.
543 3. Added a 'M' multi-volume option to dump and restore which enables
544 dumping to multiple files (useful when dumping to an ext2
545 partition to make several dump files in order to bypass the 2GB
546 file size limitation). The 'f' argument is treated as a prefix and
547 the output files will be named <prefix>001, <prefix>002 etc. With
548 the 'M' flag, restore automatically selects the right file without
549 asking to enter a new tape each time.
551 4. Fixed a memory leak which was causing dump to grow very big
552 (270MB when dumping a 10GB filesystem...). Thanks to Jason
553 Fearon <jasonf@netrider.org.au> for reporting the bug.
555 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
556 ======================================================================
558 1. Make configure test if the system glob routines support
559 extended syntax (ALTDIRFUNC). If not, use the internal glob
560 routines instead of system ones. Thanks to Bernhard Sadlowski
561 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
562 and helping me resolve this and other minor libc5 compiling
565 2. Fix a problem when dumping a ext2fs with the 'filetype'
566 feature enabled. Thanks to Patrick J. LoPresti
567 <patl@cag.lcs.mit.edu> for reporting the bug and to
568 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
570 3. Made the nodump flag work on directories. A directory which
571 has the nodump flag gets never dumped, regardless of its
574 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
575 which allows dump on an active ext3 filesystem. However, this
576 is a "quick and dirty" patch which enables backup of an ext3
577 filesystem through the ext2 compatibility (by ignoring the
578 NEEDS_RECOVERY bit). The journal file is not recognized and
579 it is dumped (it should not).
581 5. Test the superblock compatibility flags when dumping, in order
582 to be sure that we know how to deal with specific features.
584 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
585 ====================================================================
587 1. Use lchown instead of chown, fixing a possible security problem
588 when restoring symlinks (a malicious user could use this
589 to deliberately corrupt the ownership of important system files).
590 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
591 this and providing the patch.
593 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
594 ====================================================================
596 1. Put dump sources under CVS, added Id tags in all files so
597 one can use 'ident' on binary files.
599 2. Added the dump/restore version in the usage text so one can
600 easily verify the version he is using.
602 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
603 a va_start/va_end problem on linux-ppc (always call va_start
604 va_end in pairs each time we use a vararg function).
606 4. Added again the DT_* constants because old libc does not
607 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
608 for submitting the bug report.
610 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
611 this should enable dumping big (huge) filesystems.
613 6. Added the RSH environment variable in order to be able to
614 use a rsh replacement like ssh when doing remote backups (and
615 bypass the security limitations of rcmd). Now you can do remote
616 backups without being root (or making dump setuid root).
618 7. Modified again the way dumpdates works. For incremental dumps,
619 we need to read dumpdates even if we are not using 'u' option.
620 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
623 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
624 ===================================================================
626 1. Removed the 'k' flag from the restore 'about' text if kerberos
629 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
630 to them (fsetflags takes a char*, setflags an open fd!).
632 3. (f)setflags is called only if the flags aren't empty. If the
633 file is a special file, a warning is printed, because changing
634 flags implies opening the device. Normally, a special file
635 should not have any flag... (Debian bug #29775, patch provided
636 by Abhijit Dasgupta <abhijit@ans.net>).
638 4. Made possible to dump a file system not mentioned in /etc/fstab.
639 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
641 5. Changed the default behaviour to not create dumpdates
642 unless 'u' option is specified. Removed the old "debian-patch"
643 which provided the same thing. (Debian bug #38136, #33818).
645 6. Removed all those dump*announce, since they were getting old...
647 7. Added warning messages if dumpdates does not exist and
648 when an inferior level dump does not exist (except for a level 0
651 8. Debugged the glob calls in interactive mode: restore used a
652 dirent struct which was different from the /usr/include/dirent.h
653 one (this used to work, is it a glibc2 change?), so none of the
654 compat glob (which used /usr/include/dirent.h) or the system glob
655 worked. Restore use now the system dirent (and the system
656 DT_* constants), which are compatible with BSD ones.
658 9. Added a configure flag (--with-dumpdatespath) to specify
659 the location of dumpdates file. By default, it is
662 10. Added the "AUTHOR" and "AVAILABILITY" sections and
663 included the current date/version in man pages.
665 11. Corrected the estimation of remaining time when
666 the operator doesn't change the tapes quickly enough. This
667 was an old bug, I thought I corrected it, and discovered
668 that in fact it was corrected in two different places, so
669 the results canceled each other...
671 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
672 ===================================================================
674 1. Integrated multiple patches from RedHat, Debian and SuSE:
676 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
678 - several fixes in the man pages.
679 - update the default tape device to /dev/st0.
680 - many updates for Linux Alpha (byte ordering, size_t etc).
682 - use environment variable for TMPDIR (instead of /tmp).
683 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
684 - workaround egcs bug (RedHat bugs #4281 and #2989).
685 - wire $(OPT) throughout Makefile's.
687 2. Upgrade the dump revision to 1, making possible to dump filesystems
688 made with e2fsprogs-1.15 or newer. Nothing seems to break...
690 3. Fix some compile warnings, prototype all functions.
692 4. Use glibc err/glob instead of internal compatibility
693 routines (only if available).
695 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
696 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
698 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
699 ======================================================================
701 1. Integrated the changes from FreeBSD-3.1-RELEASE
702 (mostly bug fixes, buffer overruns, dump has now an "automatic
703 tape length calculation" flag, dump/restore can use kerberos now
704 (this is NOT tested), use environment variables for TAPE and
707 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
709 3. Corrected a bug in restore when using 'C' option with multi-volumes
710 tapes (files splited accros two tapes give "size changed" errors
713 4. Corrected the long standing bug when dumping multiple tapes.
714 This works for me, needs further testing.
716 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
717 ====================================================================
719 1. Dump now runs correctly on kernels 2.1.x
720 Fix made by Gerald Peters <gapeters@worldnet.att.net>
722 Changes between versions 0.4b2 and 0.4b3
723 ========================================
725 1. Use realpath() if available
729 Changes between versions 0.4b1 and 0.4b2
730 ========================================
732 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
735 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
737 3. Fixed configure.in to correctly handle --enable-rmt
739 Changes between versions 0.3 and 0.4b1
740 ======================================
742 1. Integrated the changes from 4.4BSD-Lite2
744 2. Integrated the patches from Debian and Red Hat
746 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
748 4. Changed dump to use the Ext2fs library to get block addresses. This
749 should solve the endianness problem on SparcLinux.
751 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
752 distribution's one) to use autoconf
754 6. Fixed a few minor bugs
756 Changes between versions 0.2e and 0.2f
757 ======================================
759 1. Added the creation of named pipes (fifos) in restore.
761 2. Added the -N flag in the restore manual page.
763 3. Added the file kernel.patch which contains the llseek() optimization
764 patch for 1.2.x kernels.
766 4. Fixed a bug in the restoration of symbolic links: owner and group were
769 5. Integrated some changes from FreeBSD 2.2.
771 6. Added a call to ftruncate() after restoring each file to restore
772 correctly files ending by a hole.
774 Changes between versions 0.2d and 0.2e
775 ======================================
777 1. Fixed a bug in the "set owner/mode" process. Every file was restored
778 with owner = root (0) and group = root/wheel/whatever (0).
780 Changes between versions 0.2c and 0.2d
781 ======================================
783 1. Dump is now able to backup 2GB+ filesystems.
785 2. Dump and restore can now be linked as static binaries.
787 Changes between versions 0.2b and 0.2c
788 ======================================
790 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
792 Changes between versions 0.2a and 0.2b
793 ======================================
795 1. Really fixed the bug that I should have corrected in 0.2a.
797 2. Enabled optimization again.
799 Changes between versions 0.2 and 0.2a
800 =====================================
802 1. Disabled the optimization during compilation.
804 Changes between versions 0.1 and 0.2
805 ====================================
807 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
808 the fs_type field (actually, I modified the file fstab.c to make it
809 use the mntent functions).
811 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
812 made by dump should be readable by the BSD restore and backups made
813 by the BSD dump should be readable by restore. Unfortunately, this
814 means that the dump format has changed between version 0.1 and version
817 3. Dump is now able to backup a subtree, it is no longer limited to whole
818 filesystems like the BSD version.
820 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
823 Changes between versions 0.0 and 0.1
824 ====================================
826 1. Now create links rdump and rrestore during the `make install' step.
828 2. Linux port specific bugs added to the manual pages
830 3. Incorrect estimation of the number of tapes blocks fixed when doing
833 4. Better ls-like format in restore in interactive mode.
