3 Changes between versions 0.4b22 and 0.4b23 (released ????????????)
4 ==================================================================
6 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
7 Marcus Meissner (Caldera International Security Dept.).
9 2. Implement the Sun rmt extended protocol. Patch submitted
10 by Ian Gordon <iangordon@users.sourceforge.net>.
12 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
13 the linux kernel header. This ensures that dump always has the
14 latest version of this file. Patch submitted by
15 Andreas Dilger <adilger@turbolinux.com>.
17 4. Report any filesystem present in either /etc/fstab with a
18 positive passno or /etc/dumpdates in dump -w output.
19 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
21 5. Fixed the looping problem in dump introduced in the
24 6. Changed the -B option of dump to limit the size of
25 _compressed_ output per volume if compression is on.
26 Patch contributed by Helmut Jarausch
27 <jarausch@igpm.rwth-aachen.de>.
29 7. Fixed a bug in reading the operator typed file/tape path for
30 the next volume in restore.
32 8. Implemented a "-F script" option to restore which permits the
33 user to specify a script which will be launched at the
34 beginning of each tape, useful for automatic programming of
35 tape changers for example. See the restore man page for the
36 script parameters and return codes.
38 9. Small fix for the QFA routines provided by Uwe Gohlke
39 <uwe@ugsoft.de>, and some recommendations for QFA uses in
42 10. Fixed the multivolume restoring where making a mistake
43 to the 'Mount next tape' prompt caused several blocks to
46 11. Enhanced the -e option of dump to take as a parameter a
47 comma separated list of inode numbers.
49 12. Added the -E option to dump which specify a file containing
50 inode numbers to exclude from the dump.
52 13. Fixed the compressed multi-volume dump + restore.
54 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
55 ==================================================================
57 1. Made dump report the number of blocks dumped per volume.
58 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
60 2. Fix a bug in dump where waiting too much at the 'change volumes'
61 question caused the volume to be rewritten. Thanks to
62 Graham Reed <greed@users.sourceforge.net> for reporting the
63 bug and providing a patch.
65 3. Added a compression option to dump, contributed by Jerry
66 Peters <gapeters@worldnet.att.net>.
68 WARNING: the compression works only on files/pipes and
69 drives supporting variable block size.
71 WARNING2: tapes created using the compression feature are
72 incompatible with the standard dump tape format, and a
73 version of restore >= 0.4b22 will be needed for extraction.
75 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
76 architectures. Thanks to Paul Slootman <paul@debian.org> for
77 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
80 5. Many cleanups (CPP defines, const char warnings, check of
81 ext2fs COMPAT flags, time_t cleanups, added libext2 version
82 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
84 6. Made --prefix option work in configure. All the install path
85 are now based on the configure parameters.
87 7. Added the Quick File Access mode in dump/restore, contributed
88 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
89 a file tape position for each inode, and this file is used by
90 restore (if called with parameter Q and the filename)
91 to directly position the tape at the file restore is currently
92 working on. This saves hours when restoring single files from
93 large backups, saves the tapes and the drive's head. Use
94 --enable-qfa option of configure to compile in the QFA support.
96 8. Added the possibility to dump several files and directories
97 in a single invocation of dump. Thanks to Uwe Gohlke
98 <uwe@ugsoft.de> for implementing this option.
100 9. Fixed the dumping and restoring of files with holes
101 (files ending with holes didn't get dumped or restored
104 10. Fixed a socket descriptor leak in dump, which leaved opened
105 3 file descriptors per dump process (and there is one dump
108 11. Fixed dump large file system support, by explicit use of
109 open64/lseek64/etc functions (explicit use needed because
110 e2fsprogs libraries don't behave well when compiled with
111 FILE_OFFSET_BITS=64).
113 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
114 ======================================================================
116 1. Fixed some bugs in the dump -w|-W logic introduced by
117 the previous version. Thanks to Andreas Dilger
118 <adilger@turbolinux.com> for his help on this one.
120 2. Fixed again a compilation problem when using old e2fs
121 headers (filesystem label related). Thanks to many users
122 who reported this stupid error.
124 3. Fixed a build problem on old lib5 based systems dealing with
125 _PATH_MNTTAB being undefined. Thanks to John Adams
126 <johna@onevista.com> for reporting the bug.
128 4. Improved the error detection in restore when creating
129 the temporary files in TMPDIR. Now restore will corectly
130 report a 'no space left on device' error instead of
131 strange errors which could imply an archive corruption.
132 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
133 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
135 5. Added the throughput information in dump's progression
136 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
139 6. Use libext2fs's inode scanning routines, which are particularly
140 robust when dealing with errors (especially when having some
141 bad blocks on the filesystem). Many thanks to Colin
142 <colin@horizon.com> for reporting the bug, investigating
143 the issues, finding a workaround, writing the patch and
144 fully testing it... (of course, if this patch will break
145 anything, he is to blame for :-)).
147 7. Made dump and restore LFS aware. Dump can dump a filesystem
148 containing large files, generate a large file on output and
149 restore can restore them. This feature is not enabled by
150 default, use --enable-largefile option of configure to enable
151 it (you need to have a LFS aware glibc though). Thanks to
152 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
153 and to Theodore T'so <tytso@valinux.com> for his always
156 8. Made dump ask upon a tape write error if it should rewrite
157 the current volume (assume this is a bad tape) or if it should
158 assume an end-of-tape condition (useful for tape drives which
159 behaves badly at the end of the tape). Thanks to Andreas
160 Dilger <adilger@turbolinux.com> for the suggestion.
162 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
163 =======================================================================
165 1. Fixed a small compilation problem due to a change
166 in the definintion of the struct sigaction in
167 glibc 2.0 / libc5. Thanks to Gunther Schlegel
168 <schlegel@riege.de> for reporting the bug and to
169 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
172 2. Modified the label and uuid analysis in order to be
173 self-contained (independant of kernel/libc headers). This
174 should fix the compile with older kernel/libc headers and
175 will preserve the functionality. Thanks to Bernhard Erdmann
176 <bernhard.erdmann@gmx.de> for reporting the bug.
178 3. The 'exclude inode' option, if applied to a directory
179 inode, excludes now correctly all the leaves of this
180 directory. Thanks to John R. Dennison
181 <gerdesas@users.sourceforge.net> for reporting the bug.
183 4. Fixed the '-e' option to disable the possibility
184 to exclude the root inode (which causes the dumps to
185 be unreadable by restore). Prevented array overflow
186 when multiple -e options are used.
188 5. Fixed dump to correctly interpret a filesystem argument
189 which is a mountpoint and it is not an absolute path
190 (as specified in the fstab). Thanks to Bernhard R. Erdmann
191 <be@berdmann.de> for reporting the bug.
193 6. Made dump able to backup files larger than 2 GB. Note that
194 dump still doesn't cope with files larger than 4 GB.
196 7. Restore the real uid and gid before invoking an external
197 RSH program (big hole when dump or restore is suid root!).
199 8. Get the values for the default tape device and the location
200 of fstab file from the system headers. Thanks to
201 Andreas Dilger <adilger@turbolinux.com> for the patch.
203 9. Made dump -w|-W report all recognized filesystems
204 present in either /etc/fstab or /etc/dumpdates, and present
205 the list in the same order as in fstab file. Thanks
206 to Andreas Dilger <adilger@turbolinux.com> for the patch.
208 10. Made dump's -a (automatic end of tape detection) the
209 default. Specifying one of -B, -c, -d or -s options will
210 override the EOM detection. Thanks to Andreas Dilger
211 <adilger@turbolinux.com> for the patch.
213 11. Save the ext2 filesystem label into the dump volume label.
214 Specifying a volume label on the command line (-L option)
215 will override this feature. Thanks to Andreas Dilger
216 <adilger@turbolinux.com> for the patch.
218 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
219 =====================================================================
221 1. Fixed the signal handling in dump (which I broke in 0.4b17)
222 which was causing several strange dump failures (dump
223 hanged or segmentation faults etc).
225 2. Specified the default blocksize in the dump man page.
227 3. Changed two info messages of restore to be written on stdout
228 instead of stderr in order to leave stderr only for errors
229 or warnings. Thanks to Stephen Atwell
230 <satwell@urbana.css.mot.com> for the suggestion.
232 4. Corrected an off by one calculation which prevented
233 dumping a directory having a 1 character name length.
234 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
235 for reporting the bug.
237 5. Reinforce dump in order to allow only level 0 and no
238 -u option when dumping a subdirectory, and document
239 this in the man page. Thanks to Bernhard Erdmann
240 <bernhard.erdmann@gmx.de> for reporting the bug.
242 6. Fixed a small harmless bug in restore which caused
243 in some conditions hard links to be restored several
244 times (therefore generation some warning messages).
245 Thanks to Kenneth Porter <shiva@well.com> for
248 7. Updated the RPM spec file to the latest RedHat version,
249 providing FHS packaging and other cosmetic changes.
250 You will need RPM version >= 3.0.5 in order to build the RPM.
252 8. Updated the configure script to check for libtermcap
253 before checking for libreadline, because we need this
254 library in order to compile the readline support.
256 9. Made dump understand the LABEL= and UUID= notation
257 both in /etc/fstab and on the command line. Note that
258 you will need the /proc filesystem in order to use
259 these notations. Thanks to Erik Troan <ewt@redhat.com>
260 for providing the patch.
262 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
263 ===================================================================
265 1. Fixed a potential buffer overflow in restore. Thanks
266 to Stan Bubrouski <satan@fastdial.net> for reporting
269 2. Fixed a readline-related bug which prevented
270 'cat DUMPFILE | restore -i -f -' from working. Thanks
271 to Charles Karney <karney@users.sourceforge.net>
274 3. Changed a few "panic" into "exit", causing restore to
275 be more stable against some attacks (like the last one
276 reported on Bugtraq, although the last version of restore
277 was not vulnerable - just dumped core). Thanks to
278 Andreas Hasenack <andreas@conectiva.com.br> for reporting
281 4. Removed the suid-root bit on dump and restore in the
282 default build (and generated RPMs). It should be safer
283 now. Users who need the suid-root capabilities in order
284 to make network backups should read first the man page
285 of dump and enable the suid bit manually.
287 5. Added -ltermcap to the compile parameters for restore
288 when using readline support, in order to make the compile
289 process work on some systems (SuSE ?). Thanks to
290 Patrik Schindler <poc@pocnet.net> for reporting the bug.
292 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
293 ====================================================================
295 1. The -F script is called now *only* at the end of a tape,
296 not at the end of the dump. Thanks to Christian Haul
297 <haul@informatik.tu-darmstadt.de> for the bug report.
299 Normally, the device name and the current volume number
300 are passed on the command line of the script. However,
301 if you want the old style script (with no arguments
302 passed on the command line), you can enable it in
303 configure with the --enable-oldstylefscript.
305 2. Use posix signal handling to preserve dump functionality
306 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
309 3. Made the exit code of restore in case of a 'C'ompare
310 command reflect the result of the compare. An exit status
311 of 0 means the dump archive is correct, 1 means tape errors,
312 2 means that some files were modified. Thanks to Kenneth Porter
313 <shiva@well.com> for the suggestion.
315 4. Made (finally) quotes work in interactive restore.
317 5. Small fixes in order to allow dump to compile with a
318 really old e2fsprogs version. Thanks to Ian Zimmerman
319 <itz@speakeasy.org> for the bug report.
321 6. Add GNU readline capabilities to interactive restore.
322 Use configure's --enable-readline flag to enable this feature.
323 Thanks to Patrik Schindler <poc@pocnet.net> for the
326 7. Do the compare on the fly in restore 'C' mode (this will
327 allow not to exhaust the available /tmp space when
328 ccmparing large files). Thanks to Kenneth Porter
329 <shiva@well.com> for the suggestion.
331 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
332 ====================================================================
334 1. Fixed some several duplicate 'DUMP: DUMP:' in the
337 2. Corrected the estimation of blocks to dump. Note that
338 this is still wrong for large directory inodes, due
339 to the size of a BSD directory entry on the tape
340 (estimation is based on the size of the ext2 directory,
341 which is smaller because it doesn't contain the null
342 character at the end).
344 3. Made dump report the total number of MB written to
345 tape at the end of run. Thanks to W. Reilly Cooley
346 <wcooley@nakedape.cc> for the patch.
348 4. Added the -X option to restore giving the possibility
349 to read the names of the files to be extracted/listed
350 from a text file (in addition of the command line).
351 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
354 5. Added the device name and the current volume number
355 as arguments to the end of tape script (dump -F option).
357 6. Made the multi-volume dump work again (after having
358 broken it in 0.4b15).
360 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
361 ===================================================================
363 1. Added a prompt command in interactive restore mode. Thanks
364 to Andreas Dilger <adilger@home.com> for the patch.
366 2. Fixed a buffer overflow problem in dump (caused by
367 not checking the size of the filesystem parameter).
368 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
369 reporting this on Bugtraq (and to several dump users
370 who forwarded me his mail).
372 3. Added the '-F script' option to dump in order to
373 launch a script at the end of each tape (to be used
374 with a tape changer, or to notify the sysadmin by
377 4. Fixed a bug in restore compare code caused by the changes
380 5. Fixed the treatment of options using the old BSD syntax
381 in both dump and restore.
383 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
384 =======================================================================
386 1. Fixed a bug in dump which may have caused invalid deleted
387 directories to be dumped out if they were deleted after the
388 mapping pass. This could occure on active filesystem and lead
389 to heap corruption (causing dump malfunction in many possible ways).
390 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
391 bug and submitting the patch.
393 2. Fixed the handling of the filesystem parameter in dump. A
394 '/mnt/disk' parameter caused the disk contents to be dumped,
395 but a '/mnt/disk/' parameter caused the mountpoint directory
396 to be dumped (generally an empty directory).
398 3. Improved the output of dump in order to tell which directory
399 it is currently dumping (when dumping a subtree).
401 4. Added the '-e' exclude inode option to dump. Thanks to
402 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
404 5. Added a REPORTING-BUGS file in order to provide a guide
405 on how to correctly report a bug in dump/restore.
407 6. Fixed a restore problem when restoring a hard link to an inode
408 having the immutable or append-only attribute set. Thanks to
409 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
411 7. Fixed a compatibility problem between dumps made on little
412 endian machines (the format was correct) and big endian
413 machines (the format was incorrect). This fix break the
414 compatibility with the older dumps made on big endian
415 machines (sparc, m86k, ppc etc). For the first time in
416 linux dump's history (I believe), the dumps made by *BSD,
417 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
418 so interchangeable. Thanks to Rob Cermak
419 <cermak@ahab.rutgers.edu> for submitting the bug and
420 helping me test the fix.
422 8. Fixed the way dump reports the remaining percent/time, if
423 the number of blocks actually dumped exceeds the estimated
424 number of blocks. Thanks to Jean-Paul van der Jagt
425 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
427 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
428 ======================================================================
430 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
431 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
433 2. Removed the requirement to build the RPM as root from the
434 spec file. Thanks to Christian Weisgerber
435 <naddy@mips.rhein-neckar.de> for submitting this.
437 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
438 causing dump to block when dumping really huge filesystems.
439 Many thanks to Patrik Schindler <poc@pocnet.net> for
440 helping me find this bug.
442 4. Fixed the treatment for an interrupt signal when dump access
443 the remote tape through RSH. Thanks to Christian Weisgerber
444 <naddy@mips.rhein-neckar.de> for providing the patch.
446 5. Fixed a bug which was causing dump/restore to display
447 garbage characters instead of the remote host name.
449 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
450 =====================================================================
452 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
453 <kukuk@suse.de> for submitting the patch.
455 2. Fix for the exit code when using the size estimate option of
456 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
457 submitting the patch.
459 3. Handle EINTR in atomical reads/writes in dump, which was causing
460 dump to fail on some systems. Thanks to Eric Jergensen
461 <eric@dvns.com> for reporting the bug and submitting the patch.
463 4. Handle more than 16 characters for the device names in dumpdates.
464 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
465 tracking down the problem and proposing the solution.
467 5. Fixed a bug in dump which prevented the creation of the
468 dumpdates file when doing a 0-level dump without already
469 having a dumpdates file. Thanks to Patrik Schindler
470 <poc@pocnet.net> for reporting the bug.
472 6. Changed the way dump 'S' flag reports the size estimate
473 from number of blocks into bytes (making it compatible
474 with the Solaris version, and simplifying things for
475 amanda users). Thanks to Jason L Tibbitts III
476 <tibbs@math.uh.edu> for reporting the bug.
478 7. Fixed a compatibility problem in linux/alpha dump tape format.
479 Now the linux/alpha dump are (again) compatible with the
480 other dump formats. But this breaks compatibility with
481 older dumps made on alpha. Thanks to Mike Tibor
482 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
484 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
485 ======================================================================
487 1. Added a '--enable-kerberos' to configure.
489 2. Added a 'S' option to dump which determines the amount of space
490 that is needed to perform the dump without actually doing it, similar
491 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
492 <cermak@ahab.rutgers.edu>.
494 3. Added a 'M' multi-volume option to dump and restore which enables
495 dumping to multiple files (useful when dumping to an ext2
496 partition to make several dump files in order to bypass the 2GB
497 file size limitation). The 'f' argument is treated as a prefix and
498 the output files will be named <prefix>001, <prefix>002 etc. With
499 the 'M' flag, restore automatically selects the right file without
500 asking to enter a new tape each time.
502 4. Fixed a memory leak which was causing dump to grow very big
503 (270MB when dumping a 10GB filesystem...). Thanks to Jason
504 Fearon <jasonf@netrider.org.au> for reporting the bug.
506 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
507 ======================================================================
509 1. Make configure test if the system glob routines support
510 extended syntax (ALTDIRFUNC). If not, use the internal glob
511 routines instead of system ones. Thanks to Bernhard Sadlowski
512 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
513 and helping me resolve this and other minor libc5 compiling
516 2. Fix a problem when dumping a ext2fs with the 'filetype'
517 feature enabled. Thanks to Patrick J. LoPresti
518 <patl@cag.lcs.mit.edu> for reporting the bug and to
519 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
521 3. Made the nodump flag work on directories. A directory which
522 has the nodump flag gets never dumped, regardless of its
525 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
526 which allows dump on an active ext3 filesystem. However, this
527 is a "quick and dirty" patch which enables backup of an ext3
528 filesystem through the ext2 compatibility (by ignoring the
529 NEEDS_RECOVERY bit). The journal file is not recognized and
530 it is dumped (it should not).
532 5. Test the superblock compatibility flags when dumping, in order
533 to be sure that we know how to deal with specific features.
535 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
536 ====================================================================
538 1. Use lchown instead of chown, fixing a possible security problem
539 when restoring symlinks (a malicious user could use this
540 to deliberately corrupt the ownership of important system files).
541 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
542 this and providing the patch.
544 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
545 ====================================================================
547 1. Put dump sources under CVS, added Id tags in all files so
548 one can use 'ident' on binary files.
550 2. Added the dump/restore version in the usage text so one can
551 easily verify the version he is using.
553 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
554 a va_start/va_end problem on linux-ppc (always call va_start
555 va_end in pairs each time we use a vararg function).
557 4. Added again the DT_* constants because old libc does not
558 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
559 for submitting the bug report.
561 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
562 this should enable dumping big (huge) filesystems.
564 6. Added the RSH environment variable in order to be able to
565 use a rsh replacement like ssh when doing remote backups (and
566 bypass the security limitations of rcmd). Now you can do remote
567 backups without being root (or making dump setuid root).
569 7. Modified again the way dumpdates works. For incremental dumps,
570 we need to read dumpdates even if we are not using 'u' option.
571 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
574 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
575 ===================================================================
577 1. Removed the 'k' flag from the restore 'about' text if kerberos
580 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
581 to them (fsetflags takes a char*, setflags an open fd!).
583 3. (f)setflags is called only if the flags aren't empty. If the
584 file is a special file, a warning is printed, because changing
585 flags implies opening the device. Normally, a special file
586 should not have any flag... (Debian bug #29775, patch provided
587 by Abhijit Dasgupta <abhijit@ans.net>).
589 4. Made possible to dump a file system not mentioned in /etc/fstab.
590 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
592 5. Changed the default behaviour to not create dumpdates
593 unless 'u' option is specified. Removed the old "debian-patch"
594 which provided the same thing. (Debian bug #38136, #33818).
596 6. Removed all those dump*announce, since they were getting old...
598 7. Added warning messages if dumpdates does not exist and
599 when an inferior level dump does not exist (except for a level 0
602 8. Debugged the glob calls in interactive mode: restore used a
603 dirent struct which was different from the /usr/include/dirent.h
604 one (this used to work, is it a glibc2 change?), so none of the
605 compat glob (which used /usr/include/dirent.h) or the system glob
606 worked. Restore use now the system dirent (and the system
607 DT_* constants), which are compatible with BSD ones.
609 9. Added a configure flag (--with-dumpdatespath) to specify
610 the location of dumpdates file. By default, it is
613 10. Added the "AUTHOR" and "AVAILABILITY" sections and
614 included the current date/version in man pages.
616 11. Corrected the estimation of remaining time when
617 the operator doesn't change the tapes quickly enough. This
618 was an old bug, I thought I corrected it, and discovered
619 that in fact it was corrected in two different places, so
620 the results canceled each other...
622 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
623 ===================================================================
625 1. Integrated multiple patches from RedHat, Debian and SuSE:
627 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
629 - several fixes in the man pages.
630 - update the default tape device to /dev/st0.
631 - many updates for Linux Alpha (byte ordering, size_t etc).
633 - use environment variable for TMPDIR (instead of /tmp).
634 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
635 - workaround egcs bug (RedHat bugs #4281 and #2989).
636 - wire $(OPT) throughout Makefile's.
638 2. Upgrade the dump revision to 1, making possible to dump filesystems
639 made with e2fsprogs-1.15 or newer. Nothing seems to break...
641 3. Fix some compile warnings, prototype all functions.
643 4. Use glibc err/glob instead of internal compatibility
644 routines (only if available).
646 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
647 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
649 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
650 ======================================================================
652 1. Integrated the changes from FreeBSD-3.1-RELEASE
653 (mostly bug fixes, buffer overruns, dump has now an "automatic
654 tape length calculation" flag, dump/restore can use kerberos now
655 (this is NOT tested), use environment variables for TAPE and
658 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
660 3. Corrected a bug in restore when using 'C' option with multi-volumes
661 tapes (files splited accros two tapes give "size changed" errors
664 4. Corrected the long standing bug when dumping multiple tapes.
665 This works for me, needs further testing.
667 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
668 ====================================================================
670 1. Dump now runs correctly on kernels 2.1.x
671 Fix made by Gerald Peters <gapeters@worldnet.att.net>
673 Changes between versions 0.4b2 and 0.4b3
674 ========================================
676 1. Use realpath() if available
680 Changes between versions 0.4b1 and 0.4b2
681 ========================================
683 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
686 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
688 3. Fixed configure.in to correctly handle --enable-rmt
690 Changes between versions 0.3 and 0.4b1
691 ======================================
693 1. Integrated the changes from 4.4BSD-Lite2
695 2. Integrated the patches from Debian and Red Hat
697 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
699 4. Changed dump to use the Ext2fs library to get block addresses. This
700 should solve the endianness problem on SparcLinux.
702 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
703 distribution's one) to use autoconf
705 6. Fixed a few minor bugs
707 Changes between versions 0.2e and 0.2f
708 ======================================
710 1. Added the creation of named pipes (fifos) in restore.
712 2. Added the -N flag in the restore manual page.
714 3. Added the file kernel.patch which contains the llseek() optimization
715 patch for 1.2.x kernels.
717 4. Fixed a bug in the restoration of symbolic links: owner and group were
720 5. Integrated some changes from FreeBSD 2.2.
722 6. Added a call to ftruncate() after restoring each file to restore
723 correctly files ending by a hole.
725 Changes between versions 0.2d and 0.2e
726 ======================================
728 1. Fixed a bug in the "set owner/mode" process. Every file was restored
729 with owner = root (0) and group = root/wheel/whatever (0).
731 Changes between versions 0.2c and 0.2d
732 ======================================
734 1. Dump is now able to backup 2GB+ filesystems.
736 2. Dump and restore can now be linked as static binaries.
738 Changes between versions 0.2b and 0.2c
739 ======================================
741 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
743 Changes between versions 0.2a and 0.2b
744 ======================================
746 1. Really fixed the bug that I should have corrected in 0.2a.
748 2. Enabled optimization again.
750 Changes between versions 0.2 and 0.2a
751 =====================================
753 1. Disabled the optimization during compilation.
755 Changes between versions 0.1 and 0.2
756 ====================================
758 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
759 the fs_type field (actually, I modified the file fstab.c to make it
760 use the mntent functions).
762 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
763 made by dump should be readable by the BSD restore and backups made
764 by the BSD dump should be readable by restore. Unfortunately, this
765 means that the dump format has changed between version 0.1 and version
768 3. Dump is now able to backup a subtree, it is no longer limited to whole
769 filesystems like the BSD version.
771 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
774 Changes between versions 0.0 and 0.1
775 ====================================
777 1. Now create links rdump and rrestore during the `make install' step.
779 2. Linux port specific bugs added to the manual pages
781 3. Incorrect estimation of the number of tapes blocks fixed when doing
784 4. Better ls-like format in restore in interactive mode.
