3 Changes between versions 0.4b17 and 0.4b18 (released ??????????????)
4 ====================================================================
6 1. Fixed a potential buffer overflow in restore. Thanks
7 to Stan Bubrouski <satan@fastdial.net> for reporting
10 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
11 ====================================================================
13 1. The -F script is called now *only* at the end of a tape,
14 not at the end of the dump. Thanks to Christian Haul
15 <haul@informatik.tu-darmstadt.de> for the bug report.
17 Normally, the device name and the current volume number
18 are passed on the command line of the script. However,
19 if you want the old style script (with no arguments
20 passed on the command line), you can enable it in
21 configure with the --enable-oldstylefscript.
23 2. Use posix signal handling to preserve dump functionality
24 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
27 3. Made the exit code of restore in case of a 'C'ompare
28 command reflect the result of the compare. An exit status
29 of 0 means the dump archive is correct, 1 means tape errors,
30 2 means that some files were modified. Thanks to Kenneth Porter
31 <shiva@well.com> for the suggestion.
33 4. Made (finally) quotes work in interactive restore.
35 5. Small fixes in order to allow dump to compile with a
36 really old e2fsprogs version. Thanks to Ian Zimmerman
37 <itz@speakeasy.org> for the bug report.
39 6. Add GNU readline capabilities to interactive restore.
40 Use configure's --enable-readline flag to enable this feature.
41 Thanks to Patrik Schindler <poc@pocnet.net> for the
44 7. Do the compare on the fly in restore 'C' mode (this will
45 allow not to exhaust the available /tmp space when
46 ccmparing large files). Thanks to Kenneth Porter
47 <shiva@well.com> for the suggestion.
49 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
50 ====================================================================
52 1. Fixed some several duplicate 'DUMP: DUMP:' in the
55 2. Corrected the estimation of blocks to dump. Note that
56 this is still wrong for large directory inodes, due
57 to the size of a BSD directory entry on the tape
58 (estimation is based on the size of the ext2 directory,
59 which is smaller because it doesn't contain the null
60 character at the end).
62 3. Made dump report the total number of MB written to
63 tape at the end of run. Thanks to W. Reilly Cooley
64 <wcooley@nakedape.cc> for the patch.
66 4. Added the -X option to restore giving the possibility
67 to read the names of the files to be extracted/listed
68 from a text file (in addition of the command line).
69 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
72 5. Added the device name and the current volume number
73 as arguments to the end of tape script (dump -F option).
75 6. Made the multi-volume dump work again (after having
78 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
79 ===================================================================
81 1. Added a prompt command in interactive restore mode. Thanks
82 to Andreas Dilger <adilger@home.com> for the patch.
84 2. Fixed a buffer overflow problem in dump (caused by
85 not checking the size of the filesystem parameter).
86 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
87 reporting this on Bugtraq (and to several dump users
88 who forwarded me his mail).
90 3. Added the '-F script' option to dump in order to
91 launch a script at the end of each tape (to be used
92 with a tape changer, or to notify the sysadmin by
95 4. Fixed a bug in restore compare code caused by the changes
98 5. Fixed the treatment of options using the old BSD syntax
99 in both dump and restore.
101 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
102 =======================================================================
104 1. Fixed a bug in dump which may have caused invalid deleted
105 directories to be dumped out if they were deleted after the
106 mapping pass. This could occure on active filesystem and lead
107 to heap corruption (causing dump malfunction in many possible ways).
108 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
109 bug and submitting the patch.
111 2. Fixed the handling of the filesystem parameter in dump. A
112 '/mnt/disk' parameter caused the disk contents to be dumped,
113 but a '/mnt/disk/' parameter caused the mountpoint directory
114 to be dumped (generally an empty directory).
116 3. Improved the output of dump in order to tell which directory
117 it is currently dumping (when dumping a subtree).
119 4. Added the '-e' exclude inode option to dump. Thanks to
120 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
122 5. Added a REPORTING-BUGS file in order to provide a guide
123 on how to correctly report a bug in dump/restore.
125 6. Fixed a restore problem when restoring a hard link to an inode
126 having the immutable or append-only attribute set. Thanks to
127 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
129 7. Fixed a compatibility problem between dumps made on little
130 endian machines (the format was correct) and big endian
131 machines (the format was incorrect). This fix break the
132 compatibility with the older dumps made on big endian
133 machines (sparc, m86k, ppc etc). For the first time in
134 linux dump's history (I believe), the dumps made by *BSD,
135 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
136 so interchangeable. Thanks to Rob Cermak
137 <cermak@ahab.rutgers.edu> for submitting the bug and
138 helping me test the fix.
140 8. Fixed the way dump reports the remaining percent/time, if
141 the number of blocks actually dumped exceeds the estimated
142 number of blocks. Thanks to Jean-Paul van der Jagt
143 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
145 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
146 ======================================================================
148 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
149 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
151 2. Removed the requirement to build the RPM as root from the
152 spec file. Thanks to Christian Weisgerber
153 <naddy@mips.rhein-neckar.de> for submitting this.
155 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
156 causing dump to block when dumping really huge filesystems.
157 Many thanks to Patrik Schindler <poc@pocnet.net> for
158 helping me find this bug.
160 4. Fixed the treatment for an interrupt signal when dump access
161 the remote tape through RSH. Thanks to Christian Weisgerber
162 <naddy@mips.rhein-neckar.de> for providing the patch.
164 5. Fixed a bug which was causing dump/restore to display
165 garbage characters instead of the remote host name.
167 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
168 =====================================================================
170 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
171 <kukuk@suse.de> for submitting the patch.
173 2. Fix for the exit code when using the size estimate option of
174 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
175 submitting the patch.
177 3. Handle EINTR in atomical reads/writes in dump, which was causing
178 dump to fail on some systems. Thanks to Eric Jergensen
179 <eric@dvns.com> for reporting the bug and submitting the patch.
181 4. Handle more than 16 characters for the device names in dumpdates.
182 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
183 tracking down the problem and proposing the solution.
185 5. Fixed a bug in dump which prevented the creation of the
186 dumpdates file when doing a 0-level dump without already
187 having a dumpdates file. Thanks to Patrik Schindler
188 <poc@pocnet.net> for reporting the bug.
190 6. Changed the way dump 'S' flag reports the size estimate
191 from number of blocks into bytes (making it compatible
192 with the Solaris version, and simplifying things for
193 amanda users). Thanks to Jason L Tibbitts III
194 <tibbs@math.uh.edu> for reporting the bug.
196 7. Fixed a compatibility problem in linux/alpha dump tape format.
197 Now the linux/alpha dump are (again) compatible with the
198 other dump formats. But this breaks compatibility with
199 older dumps made on alpha. Thanks to Mike Tibor
200 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
202 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
203 ======================================================================
205 1. Added a '--enable-kerberos' to configure.
207 2. Added a 'S' option to dump which determines the amount of space
208 that is needed to perform the dump without actually doing it, similar
209 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
210 <cermak@ahab.rutgers.edu>.
212 3. Added a 'M' multi-volume option to dump and restore which enables
213 dumping to multiple files (useful when dumping to an ext2
214 partition to make several dump files in order to bypass the 2GB
215 file size limitation). The 'f' argument is treated as a prefix and
216 the output files will be named <prefix>001, <prefix>002 etc. With
217 the 'M' flag, restore automatically selects the right file without
218 asking to enter a new tape each time.
220 4. Fixed a memory leak which was causing dump to grow very big
221 (270MB when dumping a 10GB filesystem...). Thanks to Jason
222 Fearon <jasonf@netrider.org.au> for reporting the bug.
224 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
225 ======================================================================
227 1. Make configure test if the system glob routines support
228 extended syntax (ALTDIRFUNC). If not, use the internal glob
229 routines instead of system ones. Thanks to Bernhard Sadlowski
230 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
231 and helping me resolve this and other minor libc5 compiling
234 2. Fix a problem when dumping a ext2fs with the 'filetype'
235 feature enabled. Thanks to Patrick J. LoPresti
236 <patl@cag.lcs.mit.edu> for reporting the bug and to
237 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
239 3. Made the nodump flag work on directories. A directory which
240 has the nodump flag gets never dumped, regardless of its
243 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
244 which allows dump on an active ext3 filesystem. However, this
245 is a "quick and dirty" patch which enables backup of an ext3
246 filesystem through the ext2 compatibility (by ignoring the
247 NEEDS_RECOVERY bit). The journal file is not recognized and
248 it is dumped (it should not).
250 5. Test the superblock compatibility flags when dumping, in order
251 to be sure that we know how to deal with specific features.
253 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
254 ====================================================================
256 1. Use lchown instead of chown, fixing a possible security problem
257 when restoring symlinks (a malicious user could use this
258 to deliberately corrupt the ownership of important system files).
259 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
260 this and providing the patch.
262 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
263 ====================================================================
265 1. Put dump sources under CVS, added Id tags in all files so
266 one can use 'ident' on binary files.
268 2. Added the dump/restore version in the usage text so one can
269 easily verify the version he is using.
271 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
272 a va_start/va_end problem on linux-ppc (always call va_start
273 va_end in pairs each time we use a vararg function).
275 4. Added again the DT_* constants because old libc does not
276 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
277 for submitting the bug report.
279 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
280 this should enable dumping big (huge) filesystems.
282 6. Added the RSH environment variable in order to be able to
283 use a rsh replacement like ssh when doing remote backups (and
284 bypass the security limitations of rcmd). Now you can do remote
285 backups without being root (or making dump setuid root).
287 7. Modified again the way dumpdates works. For incremental dumps,
288 we need to read dumpdates even if we are not using 'u' option.
289 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
292 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
293 ===================================================================
295 1. Removed the 'k' flag from the restore 'about' text if kerberos
298 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
299 to them (fsetflags takes a char*, setflags an open fd!).
301 3. (f)setflags is called only if the flags aren't empty. If the
302 file is a special file, a warning is printed, because changing
303 flags implies opening the device. Normally, a special file
304 should not have any flag... (Debian bug #29775, patch provided
305 by Abhijit Dasgupta <abhijit@ans.net>).
307 4. Made possible to dump a file system not mentioned in /etc/fstab.
308 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
310 5. Changed the default behaviour to not create dumpdates
311 unless 'u' option is specified. Removed the old "debian-patch"
312 which provided the same thing. (Debian bug #38136, #33818).
314 6. Removed all those dump*announce, since they were getting old...
316 7. Added warning messages if dumpdates does not exist and
317 when an inferior level dump does not exist (except for a level 0
320 8. Debugged the glob calls in interactive mode: restore used a
321 dirent struct which was different from the /usr/include/dirent.h
322 one (this used to work, is it a glibc2 change?), so none of the
323 compat glob (which used /usr/include/dirent.h) or the system glob
324 worked. Restore use now the system dirent (and the system
325 DT_* constants), which are compatible with BSD ones.
327 9. Added a configure flag (--with-dumpdatespath) to specify
328 the location of dumpdates file. By default, it is
331 10. Added the "AUTHOR" and "AVAILABILITY" sections and
332 included the current date/version in man pages.
334 11. Corrected the estimation of remaining time when
335 the operator doesn't change the tapes quickly enough. This
336 was an old bug, I thought I corrected it, and discovered
337 that in fact it was corrected in two different places, so
338 the results canceled each other...
340 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
341 ===================================================================
343 1. Integrated multiple patches from RedHat, Debian and SuSE:
345 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
347 - several fixes in the man pages.
348 - update the default tape device to /dev/st0.
349 - many updates for Linux Alpha (byte ordering, size_t etc).
351 - use environment variable for TMPDIR (instead of /tmp).
352 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
353 - workaround egcs bug (RedHat bugs #4281 and #2989).
354 - wire $(OPT) throughout Makefile's.
356 2. Upgrade the dump revision to 1, making possible to dump filesystems
357 made with e2fsprogs-1.15 or newer. Nothing seems to break...
359 3. Fix some compile warnings, prototype all functions.
361 4. Use glibc err/glob instead of internal compatibility
362 routines (only if available).
364 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
365 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
367 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
368 ======================================================================
370 1. Integrated the changes from FreeBSD-3.1-RELEASE
371 (mostly bug fixes, buffer overruns, dump has now an "automatic
372 tape length calculation" flag, dump/restore can use kerberos now
373 (this is NOT tested), use environment variables for TAPE and
376 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
378 3. Corrected a bug in restore when using 'C' option with multi-volumes
379 tapes (files splited accros two tapes give "size changed" errors
382 4. Corrected the long standing bug when dumping multiple tapes.
383 This works for me, needs further testing.
385 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
386 ====================================================================
388 1. Dump now runs correctly on kernels 2.1.x
389 Fix made by Gerald Peters <gapeters@worldnet.att.net>
391 Changes between versions 0.4b2 and 0.4b3
392 ========================================
394 1. Use realpath() if available
398 Changes between versions 0.4b1 and 0.4b2
399 ========================================
401 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
404 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
406 3. Fixed configure.in to correctly handle --enable-rmt
408 Changes between versions 0.3 and 0.4b1
409 ======================================
411 1. Integrated the changes from 4.4BSD-Lite2
413 2. Integrated the patches from Debian and Red Hat
415 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
417 4. Changed dump to use the Ext2fs library to get block addresses. This
418 should solve the endianness problem on SparcLinux.
420 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
421 distribution's one) to use autoconf
423 6. Fixed a few minor bugs
425 Changes between versions 0.2e and 0.2f
426 ======================================
428 1. Added the creation of named pipes (fifos) in restore.
430 2. Added the -N flag in the restore manual page.
432 3. Added the file kernel.patch which contains the llseek() optimization
433 patch for 1.2.x kernels.
435 4. Fixed a bug in the restoration of symbolic links: owner and group were
438 5. Integrated some changes from FreeBSD 2.2.
440 6. Added a call to ftruncate() after restoring each file to restore
441 correctly files ending by a hole.
443 Changes between versions 0.2d and 0.2e
444 ======================================
446 1. Fixed a bug in the "set owner/mode" process. Every file was restored
447 with owner = root (0) and group = root/wheel/whatever (0).
449 Changes between versions 0.2c and 0.2d
450 ======================================
452 1. Dump is now able to backup 2GB+ filesystems.
454 2. Dump and restore can now be linked as static binaries.
456 Changes between versions 0.2b and 0.2c
457 ======================================
459 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
461 Changes between versions 0.2a and 0.2b
462 ======================================
464 1. Really fixed the bug that I should have corrected in 0.2a.
466 2. Enabled optimization again.
468 Changes between versions 0.2 and 0.2a
469 =====================================
471 1. Disabled the optimization during compilation.
473 Changes between versions 0.1 and 0.2
474 ====================================
476 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
477 the fs_type field (actually, I modified the file fstab.c to make it
478 use the mntent functions).
480 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
481 made by dump should be readable by the BSD restore and backups made
482 by the BSD dump should be readable by restore. Unfortunately, this
483 means that the dump format has changed between version 0.1 and version
486 3. Dump is now able to backup a subtree, it is no longer limited to whole
487 filesystems like the BSD version.
489 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
492 Changes between versions 0.0 and 0.1
493 ====================================
495 1. Now create links rdump and rrestore during the `make install' step.
497 2. Linux port specific bugs added to the manual pages
499 3. Incorrect estimation of the number of tapes blocks fixed when doing
502 4. Better ls-like format in restore in interactive mode.
