3 Changes between versions 0.4b15 and 0.4b16 (released ?????????????)
4 ===================================================================
6 1. Fixed some several duplicate 'DUMP: DUMP:' in the
9 2. Corrected the estimation of blocks to dump. Note that
10 this is still wrong for large directory inodes, due
11 to the size of a BSD directory entry on the tape
12 (estimation is based on the size of the ext2 directory,
13 which is smaller because it doesn't contain the null
14 character at the end).
16 3. Made dump report the total number of MB written to
17 tape at the end of run. Thanks to W. Reilly Cooley
18 <wcooley@nakedape.cc> for the patch.
20 4. Added the -X option to restore giving the possibility
21 to read the names of the files to be extracted/listed
22 from a text file (in addition of the command line).
23 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
26 5. Added the device name and the current volume number
27 as arguments to the end of tape script (dump -F option).
29 6. Made the multi-volume dump work again (after having
32 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
33 ===================================================================
35 1. Added a prompt command in interactive restore mode. Thanks
36 to Andreas Dilger <adilger@home.com> for the patch.
38 2. Fixed a buffer overflow problem in dump (caused by
39 not checking the size of the filesystem parameter).
40 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
41 reporting this on Bugtraq (and to several dump users
42 who forwarded me his mail).
44 3. Added the '-F script' option to dump in order to
45 launch a script at the end of each tape (to be used
46 with a tape changer, or to notify the sysadmin by
49 4. Fixed a bug in restore compare code caused by the changes
52 5. Fixed the treatment of options using the old BSD syntax
53 in both dump and restore.
55 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
56 =======================================================================
58 1. Fixed a bug in dump which may have caused invalid deleted
59 directories to be dumped out if they were deleted after the
60 mapping pass. This could occure on active filesystem and lead
61 to heap corruption (causing dump malfunction in many possible ways).
62 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
63 bug and submitting the patch.
65 2. Fixed the handling of the filesystem parameter in dump. A
66 '/mnt/disk' parameter caused the disk contents to be dumped,
67 but a '/mnt/disk/' parameter caused the mountpoint directory
68 to be dumped (generally an empty directory).
70 3. Improved the output of dump in order to tell which directory
71 it is currently dumping (when dumping a subtree).
73 4. Added the '-e' exclude inode option to dump. Thanks to
74 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
76 5. Added a REPORTING-BUGS file in order to provide a guide
77 on how to correctly report a bug in dump/restore.
79 6. Fixed a restore problem when restoring a hard link to an inode
80 having the immutable or append-only attribute set. Thanks to
81 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
83 7. Fixed a compatibility problem between dumps made on little
84 endian machines (the format was correct) and big endian
85 machines (the format was incorrect). This fix break the
86 compatibility with the older dumps made on big endian
87 machines (sparc, m86k, ppc etc). For the first time in
88 linux dump's history (I believe), the dumps made by *BSD,
89 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
90 so interchangeable. Thanks to Rob Cermak
91 <cermak@ahab.rutgers.edu> for submitting the bug and
92 helping me test the fix.
94 8. Fixed the way dump reports the remaining percent/time, if
95 the number of blocks actually dumped exceeds the estimated
96 number of blocks. Thanks to Jean-Paul van der Jagt
97 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
99 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
100 ======================================================================
102 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
103 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
105 2. Removed the requirement to build the RPM as root from the
106 spec file. Thanks to Christian Weisgerber
107 <naddy@mips.rhein-neckar.de> for submitting this.
109 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
110 causing dump to block when dumping really huge filesystems.
111 Many thanks to Patrik Schindler <poc@pocnet.net> for
112 helping me find this bug.
114 4. Fixed the treatment for an interrupt signal when dump access
115 the remote tape through RSH. Thanks to Christian Weisgerber
116 <naddy@mips.rhein-neckar.de> for providing the patch.
118 5. Fixed a bug which was causing dump/restore to display
119 garbage characters instead of the remote host name.
121 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
122 =====================================================================
124 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
125 <kukuk@suse.de> for submitting the patch.
127 2. Fix for the exit code when using the size estimate option of
128 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
129 submitting the patch.
131 3. Handle EINTR in atomical reads/writes in dump, which was causing
132 dump to fail on some systems. Thanks to Eric Jergensen
133 <eric@dvns.com> for reporting the bug and submitting the patch.
135 4. Handle more than 16 characters for the device names in dumpdates.
136 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
137 tracking down the problem and proposing the solution.
139 5. Fixed a bug in dump which prevented the creation of the
140 dumpdates file when doing a 0-level dump without already
141 having a dumpdates file. Thanks to Patrik Schindler
142 <poc@pocnet.net> for reporting the bug.
144 6. Changed the way dump 'S' flag reports the size estimate
145 from number of blocks into bytes (making it compatible
146 with the Solaris version, and simplifying things for
147 amanda users). Thanks to Jason L Tibbitts III
148 <tibbs@math.uh.edu> for reporting the bug.
150 7. Fixed a compatibility problem in linux/alpha dump tape format.
151 Now the linux/alpha dump are (again) compatible with the
152 other dump formats. But this breaks compatibility with
153 older dumps made on alpha. Thanks to Mike Tibor
154 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
156 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
157 ======================================================================
159 1. Added a '--enable-kerberos' to configure.
161 2. Added a 'S' option to dump which determines the amount of space
162 that is needed to perform the dump without actually doing it, similar
163 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
164 <cermak@ahab.rutgers.edu>.
166 3. Added a 'M' multi-volume option to dump and restore which enables
167 dumping to multiple files (useful when dumping to an ext2
168 partition to make several dump files in order to bypass the 2GB
169 file size limitation). The 'f' argument is treated as a prefix and
170 the output files will be named <prefix>001, <prefix>002 etc. With
171 the 'M' flag, restore automatically selects the right file without
172 asking to enter a new tape each time.
174 4. Fixed a memory leak which was causing dump to grow very big
175 (270MB when dumping a 10GB filesystem...). Thanks to Jason
176 Fearon <jasonf@netrider.org.au> for reporting the bug.
178 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
179 ======================================================================
181 1. Make configure test if the system glob routines support
182 extended syntax (ALTDIRFUNC). If not, use the internal glob
183 routines instead of system ones. Thanks to Bernhard Sadlowski
184 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
185 and helping me resolve this and other minor libc5 compiling
188 2. Fix a problem when dumping a ext2fs with the 'filetype'
189 feature enabled. Thanks to Patrick J. LoPresti
190 <patl@cag.lcs.mit.edu> for reporting the bug and to
191 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
193 3. Made the nodump flag work on directories. A directory which
194 has the nodump flag gets never dumped, regardless of its
197 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
198 which allows dump on an active ext3 filesystem. However, this
199 is a "quick and dirty" patch which enables backup of an ext3
200 filesystem through the ext2 compatibility (by ignoring the
201 NEEDS_RECOVERY bit). The journal file is not recognized and
202 it is dumped (it should not).
204 5. Test the superblock compatibility flags when dumping, in order
205 to be sure that we know how to deal with specific features.
207 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
208 ====================================================================
210 1. Use lchown instead of chown, fixing a possible security problem
211 when restoring symlinks (a malicious user could use this
212 to deliberately corrupt the ownership of important system files).
213 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
214 this and providing the patch.
216 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
217 ====================================================================
219 1. Put dump sources under CVS, added Id tags in all files so
220 one can use 'ident' on binary files.
222 2. Added the dump/restore version in the usage text so one can
223 easily verify the version he is using.
225 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
226 a va_start/va_end problem on linux-ppc (always call va_start
227 va_end in pairs each time we use a vararg function).
229 4. Added again the DT_* constants because old libc does not
230 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
231 for submitting the bug report.
233 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
234 this should enable dumping big (huge) filesystems.
236 6. Added the RSH environment variable in order to be able to
237 use a rsh replacement like ssh when doing remote backups (and
238 bypass the security limitations of rcmd). Now you can do remote
239 backups without being root (or making dump setuid root).
241 7. Modified again the way dumpdates works. For incremental dumps,
242 we need to read dumpdates even if we are not using 'u' option.
243 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
246 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
247 ===================================================================
249 1. Removed the 'k' flag from the restore 'about' text if kerberos
252 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
253 to them (fsetflags takes a char*, setflags an open fd!).
255 3. (f)setflags is called only if the flags aren't empty. If the
256 file is a special file, a warning is printed, because changing
257 flags implies opening the device. Normally, a special file
258 should not have any flag... (Debian bug #29775, patch provided
259 by Abhijit Dasgupta <abhijit@ans.net>).
261 4. Made possible to dump a file system not mentioned in /etc/fstab.
262 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
264 5. Changed the default behaviour to not create dumpdates
265 unless 'u' option is specified. Removed the old "debian-patch"
266 which provided the same thing. (Debian bug #38136, #33818).
268 6. Removed all those dump*announce, since they were getting old...
270 7. Added warning messages if dumpdates does not exist and
271 when an inferior level dump does not exist (except for a level 0
274 8. Debugged the glob calls in interactive mode: restore used a
275 dirent struct which was different from the /usr/include/dirent.h
276 one (this used to work, is it a glibc2 change?), so none of the
277 compat glob (which used /usr/include/dirent.h) or the system glob
278 worked. Restore use now the system dirent (and the system
279 DT_* constants), which are compatible with BSD ones.
281 9. Added a configure flag (--with-dumpdatespath) to specify
282 the location of dumpdates file. By default, it is
285 10. Added the "AUTHOR" and "AVAILABILITY" sections and
286 included the current date/version in man pages.
288 11. Corrected the estimation of remaining time when
289 the operator doesn't change the tapes quickly enough. This
290 was an old bug, I thought I corrected it, and discovered
291 that in fact it was corrected in two different places, so
292 the results canceled each other...
294 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
295 ===================================================================
297 1. Integrated multiple patches from RedHat, Debian and SuSE:
299 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
301 - several fixes in the man pages.
302 - update the default tape device to /dev/st0.
303 - many updates for Linux Alpha (byte ordering, size_t etc).
305 - use environment variable for TMPDIR (instead of /tmp).
306 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
307 - workaround egcs bug (RedHat bugs #4281 and #2989).
308 - wire $(OPT) throughout Makefile's.
310 2. Upgrade the dump revision to 1, making possible to dump filesystems
311 made with e2fsprogs-1.15 or newer. Nothing seems to break...
313 3. Fix some compile warnings, prototype all functions.
315 4. Use glibc err/glob instead of internal compatibility
316 routines (only if available).
318 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
319 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
321 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
322 ======================================================================
324 1. Integrated the changes from FreeBSD-3.1-RELEASE
325 (mostly bug fixes, buffer overruns, dump has now an "automatic
326 tape length calculation" flag, dump/restore can use kerberos now
327 (this is NOT tested), use environment variables for TAPE and
330 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
332 3. Corrected a bug in restore when using 'C' option with multi-volumes
333 tapes (files splited accros two tapes give "size changed" errors
336 4. Corrected the long standing bug when dumping multiple tapes.
337 This works for me, needs further testing.
339 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
340 ====================================================================
342 1. Dump now runs correctly on kernels 2.1.x
343 Fix made by Gerald Peters <gapeters@worldnet.att.net>
345 Changes between versions 0.4b2 and 0.4b3
346 ========================================
348 1. Use realpath() if available
352 Changes between versions 0.4b1 and 0.4b2
353 ========================================
355 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
358 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
360 3. Fixed configure.in to correctly handle --enable-rmt
362 Changes between versions 0.3 and 0.4b1
363 ======================================
365 1. Integrated the changes from 4.4BSD-Lite2
367 2. Integrated the patches from Debian and Red Hat
369 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
371 4. Changed dump to use the Ext2fs library to get block addresses. This
372 should solve the endianness problem on SparcLinux.
374 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
375 distribution's one) to use autoconf
377 6. Fixed a few minor bugs
379 Changes between versions 0.2e and 0.2f
380 ======================================
382 1. Added the creation of named pipes (fifos) in restore.
384 2. Added the -N flag in the restore manual page.
386 3. Added the file kernel.patch which contains the llseek() optimization
387 patch for 1.2.x kernels.
389 4. Fixed a bug in the restoration of symbolic links: owner and group were
392 5. Integrated some changes from FreeBSD 2.2.
394 6. Added a call to ftruncate() after restoring each file to restore
395 correctly files ending by a hole.
397 Changes between versions 0.2d and 0.2e
398 ======================================
400 1. Fixed a bug in the "set owner/mode" process. Every file was restored
401 with owner = root (0) and group = root/wheel/whatever (0).
403 Changes between versions 0.2c and 0.2d
404 ======================================
406 1. Dump is now able to backup 2GB+ filesystems.
408 2. Dump and restore can now be linked as static binaries.
410 Changes between versions 0.2b and 0.2c
411 ======================================
413 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
415 Changes between versions 0.2a and 0.2b
416 ======================================
418 1. Really fixed the bug that I should have corrected in 0.2a.
420 2. Enabled optimization again.
422 Changes between versions 0.2 and 0.2a
423 =====================================
425 1. Disabled the optimization during compilation.
427 Changes between versions 0.1 and 0.2
428 ====================================
430 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
431 the fs_type field (actually, I modified the file fstab.c to make it
432 use the mntent functions).
434 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
435 made by dump should be readable by the BSD restore and backups made
436 by the BSD dump should be readable by restore. Unfortunately, this
437 means that the dump format has changed between version 0.1 and version
440 3. Dump is now able to backup a subtree, it is no longer limited to whole
441 filesystems like the BSD version.
443 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
446 Changes between versions 0.0 and 0.1
447 ====================================
449 1. Now create links rdump and rrestore during the `make install' step.
451 2. Linux port specific bugs added to the manual pages
453 3. Incorrect estimation of the number of tapes blocks fixed when doing
456 4. Better ls-like format in restore in interactive mode.
