2 | ||
3 | Changes between versions 0.4b24 and 0.4b25 (released ??????????????????) | |
4 | ======================================================================== | |
5 | ||
6 | 1. Added a mini howto from Patrick Walsh in the examples | |
7 | directory. | |
8 | ||
9 | 2. Minor man pages syntax corrections. Thanks to | |
10 | Chris Danis <screechco@home.com> for reporting the bugs. | |
11 | ||
12 | 3. Added a script from David B. Peterson <dave@toppledwagon.com> | |
13 | to the examples section. It features dumping several | |
14 | filesystems to a remote tape drive upon ssh. | |
15 | ||
16 | 4. Added a patch provided by Richard Jones <rich@annexia.org> | |
17 | which allows BRADEMAX (number of read errors tolerated by | |
18 | dump) to be adjusted using the -I option. | |
19 | ||
20 | 5. Fixed a bug which disabled doing "restore -C -f -". Thanks | |
21 | to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the | |
22 | patch. | |
23 | ||
24 | 6. Add the -l option to restore to specify if, when doing a | |
25 | remote restore, the file used to access the backup is a | |
26 | regular file (the defaults being a tape drive). Restore needs | |
27 | to know this information when reading a remote compressed | |
28 | dump. Previously, this information was autodetected, but | |
29 | the autodetection code fails (with ioctl: Inappropriate ioctl | |
30 | for device) when using a non Linux remote box. | |
31 | ||
32 | Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001) | |
33 | ======================================================================== | |
34 | ||
35 | 1. Fixed the permissions of a newly created QFA file by dump. | |
36 | ||
37 | 2. Cleaned up the source of dump (the external variables | |
38 | definition was a complete mess, making possible to have | |
39 | objects overlap). | |
40 | ||
41 | 3. Fixed restore to use the full tape volume path when doing | |
42 | a compare (since it changes the working directory to the | |
43 | filesystem being compared in the process). | |
44 | ||
45 | 4. Added the -q option to dump which makes dump abort | |
46 | whenever it needs operator attention. It should be | |
47 | easier to use dump in scripts with this option. | |
48 | ||
49 | 5. Detect the use of incompatible options to dump and | |
50 | refuse them (like -a and -B options together). | |
51 | ||
52 | 6. Added bzip2 compression to dump/restore (use option -j level | |
53 | to select it). Note that you will need a restore version | |
54 | >= 0.4b24 in order to restore a bzip2 compressed dump. | |
55 | The same warning as for the zlib compression applies: | |
56 | the tape format of a bzip2 dump is not compatible with the | |
57 | original BSD tape format. | |
58 | ||
59 | 7. Fixed a overflow problem in dump corrupting the dump when | |
60 | very large files were encountered. Thanks to Vladimir Nadvornik | |
61 | for the bug report. | |
62 | ||
63 | 8. Added a ioctl(BLKFLSBUF) in dump which should flush the | |
64 | kernel buffer/page cache before starting the dump, helping | |
65 | a bit those who use dump on mounted filesystems. Thanks to | |
66 | John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu> | |
67 | for this suggestion. | |
68 | ||
69 | 9. Updated the RPM spec file following the RedHat changes | |
70 | (dynamically linked binaries now in /usr/sbin etc). | |
71 | ||
72 | 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de> | |
73 | which enables restore to recognise multi volume compressed dumps | |
74 | done on CD. Included his scripts for dump (which pipe the dump | |
75 | output directly into cdrecord) and restore. There is now | |
76 | possible to to backups to CD on the fly! | |
77 | ||
78 | Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001) | |
79 | =================================================================== | |
80 | ||
81 | 1. Fixed a buffer overflow in restore/tape.c. Patch provided by | |
82 | Marcus Meissner (Caldera International Security Dept.). | |
83 | ||
84 | 2. Implement the Sun rmt extended protocol. Patch submitted | |
85 | by Ian Gordon <iangordon@users.sourceforge.net>. | |
86 | ||
87 | 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of | |
88 | the linux kernel header. This ensures that dump always has the | |
89 | latest version of this file. Patch submitted by | |
90 | Andreas Dilger <adilger@turbolinux.com>. | |
91 | ||
92 | 4. Report any filesystem present in either /etc/fstab with a | |
93 | positive passno or /etc/dumpdates in dump -w output. | |
94 | Patch submitted by Andreas Dilger <adilger@turbolinux.com>. | |
95 | ||
96 | 5. Fixed the looping problem in dump introduced in the | |
97 | previous version. | |
98 | ||
99 | 6. Changed the -B option of dump to limit the size of | |
100 | _compressed_ output per volume if compression is on. | |
101 | Patch contributed by Helmut Jarausch | |
102 | <jarausch@igpm.rwth-aachen.de>. Note however that, since | |
103 | it is impossible to predict the size of the compressed | |
104 | data before doing the compression, the -B limit is a bit | |
105 | conservative. | |
106 | ||
107 | 7. Fixed a bug in reading the operator typed file/tape path for | |
108 | the next volume in restore. | |
109 | ||
110 | 8. Implemented a "-F script" option to restore which permits the | |
111 | user to specify a script which will be launched at the | |
112 | beginning of each tape, useful for automatic programming of | |
113 | tape changers for example. See the restore man page for the | |
114 | script parameters and return codes. | |
115 | ||
116 | 9. Small fix for the QFA routines provided by Uwe Gohlke | |
117 | <uwe@ugsoft.de>, and some recommendations for QFA uses in | |
118 | the man pages. | |
119 | ||
120 | 10. Fixed the multivolume restoring where making a mistake | |
121 | to the 'Mount next tape' prompt caused several blocks to | |
122 | be lost. | |
123 | ||
124 | 11. Enhanced the -e option of dump to take as a parameter a | |
125 | comma separated list of inode numbers. | |
126 | ||
127 | 12. Added the -E option to dump which specify a file containing | |
128 | inode numbers to exclude from the dump. | |
129 | ||
130 | 13. Fixed the compressed multi-volume dump + restore. | |
131 | ||
132 | Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001) | |
133 | ================================================================== | |
134 | ||
135 | 1. Made dump report the number of blocks dumped per volume. | |
136 | Thanks to Kenneth Porter <shiva@well.com> for the suggestion. | |
137 | ||
138 | 2. Fix a bug in dump where waiting too much at the 'change volumes' | |
139 | question caused the volume to be rewritten. Thanks to | |
140 | Graham Reed <greed@users.sourceforge.net> for reporting the | |
141 | bug and providing a patch. | |
142 | ||
143 | 3. Added a compression option to dump, contributed by Jerry | |
144 | Peters <gapeters@worldnet.att.net>. | |
145 | ||
146 | WARNING: the compression works only on files/pipes and | |
147 | drives supporting variable block size. | |
148 | ||
149 | WARNING2: tapes created using the compression feature are | |
150 | incompatible with the standard dump tape format, and a | |
151 | version of restore >= 0.4b22 will be needed for extraction. | |
152 | ||
153 | 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit | |
154 | architectures. Thanks to Paul Slootman <paul@debian.org> for | |
155 | the patch and to Bdale Garbee <bdale@gag.com> for forwarding | |
156 | it upstream. | |
157 | ||
158 | 5. Many cleanups (CPP defines, const char warnings, check of | |
159 | ext2fs COMPAT flags, time_t cleanups, added libext2 version | |
160 | in dump usage text) by Andreas Dilger <adilger@turbolinux.com>. | |
161 | ||
162 | 6. Made --prefix option work in configure. All the install path | |
163 | are now based on the configure parameters. | |
164 | ||
165 | 7. Added the Quick File Access mode in dump/restore, contributed | |
166 | by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in | |
167 | a file tape position for each inode, and this file is used by | |
168 | restore (if called with parameter Q and the filename) | |
169 | to directly position the tape at the file restore is currently | |
170 | working on. This saves hours when restoring single files from | |
171 | large backups, saves the tapes and the drive's head. Use | |
172 | --enable-qfa option of configure to compile in the QFA support. | |
173 | ||
174 | 8. Added the possibility to dump several files and directories | |
175 | in a single invocation of dump. Thanks to Uwe Gohlke | |
176 | <uwe@ugsoft.de> for implementing this option. | |
177 | ||
178 | 9. Fixed the dumping and restoring of files with holes | |
179 | (files ending with holes didn't get dumped or restored | |
180 | correctly). | |
181 | ||
182 | 10. Fixed a socket descriptor leak in dump, which leaved opened | |
183 | 3 file descriptors per dump process (and there is one dump | |
184 | process per tape). | |
185 | ||
186 | 11. Fixed dump large file system support, by explicit use of | |
187 | open64/lseek64/etc functions (explicit use needed because | |
188 | e2fsprogs libraries don't behave well when compiled with | |
189 | FILE_OFFSET_BITS=64). | |
190 | ||
191 | Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001) | |
192 | ====================================================================== | |
193 | ||
194 | 1. Fixed some bugs in the dump -w|-W logic introduced by | |
195 | the previous version. Thanks to Andreas Dilger | |
196 | <adilger@turbolinux.com> for his help on this one. | |
197 | ||
198 | 2. Fixed again a compilation problem when using old e2fs | |
199 | headers (filesystem label related). Thanks to many users | |
200 | who reported this stupid error. | |
201 | ||
202 | 3. Fixed a build problem on old lib5 based systems dealing with | |
203 | _PATH_MNTTAB being undefined. Thanks to John Adams | |
204 | <johna@onevista.com> for reporting the bug. | |
205 | ||
206 | 4. Improved the error detection in restore when creating | |
207 | the temporary files in TMPDIR. Now restore will corectly | |
208 | report a 'no space left on device' error instead of | |
209 | strange errors which could imply an archive corruption. | |
210 | Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and | |
211 | bgjenero <bgjenero@sympatico.ca> for reporting the bug. | |
212 | ||
213 | 5. Added the throughput information in dump's progression | |
214 | messages. Thanks to Andreas Dilger <adilger@turbolinux.com> | |
215 | for the patch. | |
216 | ||
217 | 6. Use libext2fs's inode scanning routines, which are particularly | |
218 | robust when dealing with errors (especially when having some | |
219 | bad blocks on the filesystem). Many thanks to Colin | |
220 | <colin@horizon.com> for reporting the bug, investigating | |
221 | the issues, finding a workaround, writing the patch and | |
222 | fully testing it... (of course, if this patch will break | |
223 | anything, he is to blame for :-)). | |
224 | ||
225 | 7. Made dump and restore LFS aware. Dump can dump a filesystem | |
226 | containing large files, generate a large file on output and | |
227 | restore can restore them. This feature is not enabled by | |
228 | default, use --enable-largefile option of configure to enable | |
229 | it (you need to have a LFS aware glibc though). Thanks to | |
230 | Andrea Arcangeli <andrea@suse.de> for submitting the patch, | |
231 | and to Theodore T'so <tytso@valinux.com> for his always | |
232 | useful thoughts. | |
233 | ||
234 | 8. Made dump ask upon a tape write error if it should rewrite | |
235 | the current volume (assume this is a bad tape) or if it should | |
236 | assume an end-of-tape condition (useful for tape drives which | |
237 | behaves badly at the end of the tape). Thanks to Andreas | |
238 | Dilger <adilger@turbolinux.com> for the suggestion. | |
239 | ||
240 | Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000) | |
241 | ======================================================================= | |
242 | ||
243 | 1. Fixed a small compilation problem due to a change | |
244 | in the definintion of the struct sigaction in | |
245 | glibc 2.0 / libc5. Thanks to Gunther Schlegel | |
246 | <schlegel@riege.de> for reporting the bug and to | |
247 | Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting | |
248 | a fix. | |
249 | ||
250 | 2. Modified the label and uuid analysis in order to be | |
251 | self-contained (independant of kernel/libc headers). This | |
252 | should fix the compile with older kernel/libc headers and | |
253 | will preserve the functionality. Thanks to Bernhard Erdmann | |
254 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
255 | ||
256 | 3. The 'exclude inode' option, if applied to a directory | |
257 | inode, excludes now correctly all the leaves of this | |
258 | directory. Thanks to John R. Dennison | |
259 | <gerdesas@users.sourceforge.net> for reporting the bug. | |
260 | ||
261 | 4. Fixed the '-e' option to disable the possibility | |
262 | to exclude the root inode (which causes the dumps to | |
263 | be unreadable by restore). Prevented array overflow | |
264 | when multiple -e options are used. | |
265 | ||
266 | 5. Fixed dump to correctly interpret a filesystem argument | |
267 | which is a mountpoint and it is not an absolute path | |
268 | (as specified in the fstab). Thanks to Bernhard R. Erdmann | |
269 | <be@berdmann.de> for reporting the bug. | |
270 | ||
271 | 6. Made dump able to backup files larger than 2 GB. Note that | |
272 | dump still doesn't cope with files larger than 4 GB. | |
273 | ||
274 | 7. Restore the real uid and gid before invoking an external | |
275 | RSH program (big hole when dump or restore is suid root!). | |
276 | ||
277 | 8. Get the values for the default tape device and the location | |
278 | of fstab file from the system headers. Thanks to | |
279 | Andreas Dilger <adilger@turbolinux.com> for the patch. | |
280 | ||
281 | 9. Made dump -w|-W report all recognized filesystems | |
282 | present in either /etc/fstab or /etc/dumpdates, and present | |
283 | the list in the same order as in fstab file. Thanks | |
284 | to Andreas Dilger <adilger@turbolinux.com> for the patch. | |
285 | ||
286 | 10. Made dump's -a (automatic end of tape detection) the | |
287 | default. Specifying one of -B, -c, -d or -s options will | |
288 | override the EOM detection. Thanks to Andreas Dilger | |
289 | <adilger@turbolinux.com> for the patch. | |
290 | ||
291 | 11. Save the ext2 filesystem label into the dump volume label. | |
292 | Specifying a volume label on the command line (-L option) | |
293 | will override this feature. Thanks to Andreas Dilger | |
294 | <adilger@turbolinux.com> for the patch. | |
295 | ||
296 | Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000) | |
297 | ===================================================================== | |
298 | ||
299 | 1. Fixed the signal handling in dump (which I broke in 0.4b17) | |
300 | which was causing several strange dump failures (dump | |
301 | hanged or segmentation faults etc). | |
302 | ||
303 | 2. Specified the default blocksize in the dump man page. | |
304 | ||
305 | 3. Changed two info messages of restore to be written on stdout | |
306 | instead of stderr in order to leave stderr only for errors | |
307 | or warnings. Thanks to Stephen Atwell | |
308 | <satwell@urbana.css.mot.com> for the suggestion. | |
309 | ||
310 | 4. Corrected an off by one calculation which prevented | |
311 | dumping a directory having a 1 character name length. | |
312 | Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de> | |
313 | for reporting the bug. | |
314 | ||
315 | 5. Reinforce dump in order to allow only level 0 and no | |
316 | -u option when dumping a subdirectory, and document | |
317 | this in the man page. Thanks to Bernhard Erdmann | |
318 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
319 | ||
320 | 6. Fixed a small harmless bug in restore which caused | |
321 | in some conditions hard links to be restored several | |
322 | times (therefore generation some warning messages). | |
323 | Thanks to Kenneth Porter <shiva@well.com> for | |
324 | reporting the bug. | |
325 | ||
326 | 7. Updated the RPM spec file to the latest RedHat version, | |
327 | providing FHS packaging and other cosmetic changes. | |
328 | You will need RPM version >= 3.0.5 in order to build the RPM. | |
329 | ||
330 | 8. Updated the configure script to check for libtermcap | |
331 | before checking for libreadline, because we need this | |
332 | library in order to compile the readline support. | |
333 | ||
334 | 9. Made dump understand the LABEL= and UUID= notation | |
335 | both in /etc/fstab and on the command line. Note that | |
336 | you will need the /proc filesystem in order to use | |
337 | these notations. Thanks to Erik Troan <ewt@redhat.com> | |
338 | for providing the patch. | |
339 | ||
340 | Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000) | |
341 | =================================================================== | |
342 | ||
343 | 1. Fixed a potential buffer overflow in restore. Thanks | |
344 | to Stan Bubrouski <satan@fastdial.net> for reporting | |
345 | the bug. | |
346 | ||
347 | 2. Fixed a readline-related bug which prevented | |
348 | 'cat DUMPFILE | restore -i -f -' from working. Thanks | |
349 | to Charles Karney <karney@users.sourceforge.net> | |
350 | for the bug report. | |
351 | ||
352 | 3. Changed a few "panic" into "exit", causing restore to | |
353 | be more stable against some attacks (like the last one | |
354 | reported on Bugtraq, although the last version of restore | |
355 | was not vulnerable - just dumped core). Thanks to | |
356 | Andreas Hasenack <andreas@conectiva.com.br> for reporting | |
357 | the bugs to me. | |
358 | ||
359 | 4. Removed the suid-root bit on dump and restore in the | |
360 | default build (and generated RPMs). It should be safer | |
361 | now. Users who need the suid-root capabilities in order | |
362 | to make network backups should read first the man page | |
363 | of dump and enable the suid bit manually. | |
364 | ||
365 | 5. Added -ltermcap to the compile parameters for restore | |
366 | when using readline support, in order to make the compile | |
367 | process work on some systems (SuSE ?). Thanks to | |
368 | Patrik Schindler <poc@pocnet.net> for reporting the bug. | |
369 | ||
370 | Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) | |
371 | ==================================================================== | |
372 | ||
373 | 1. The -F script is called now *only* at the end of a tape, | |
374 | not at the end of the dump. Thanks to Christian Haul | |
375 | <haul@informatik.tu-darmstadt.de> for the bug report. | |
376 | ||
377 | Normally, the device name and the current volume number | |
378 | are passed on the command line of the script. However, | |
379 | if you want the old style script (with no arguments | |
380 | passed on the command line), you can enable it in | |
381 | configure with the --enable-oldstylefscript. | |
382 | ||
383 | 2. Use posix signal handling to preserve dump functionality | |
384 | with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for | |
385 | the patch. | |
386 | ||
387 | 3. Made the exit code of restore in case of a 'C'ompare | |
388 | command reflect the result of the compare. An exit status | |
389 | of 0 means the dump archive is correct, 1 means tape errors, | |
390 | 2 means that some files were modified. Thanks to Kenneth Porter | |
391 | <shiva@well.com> for the suggestion. | |
392 | ||
393 | 4. Made (finally) quotes work in interactive restore. | |
394 | ||
395 | 5. Small fixes in order to allow dump to compile with a | |
396 | really old e2fsprogs version. Thanks to Ian Zimmerman | |
397 | <itz@speakeasy.org> for the bug report. | |
398 | ||
399 | 6. Add GNU readline capabilities to interactive restore. | |
400 | Use configure's --enable-readline flag to enable this feature. | |
401 | Thanks to Patrik Schindler <poc@pocnet.net> for the | |
402 | suggestion. | |
403 | ||
404 | 7. Do the compare on the fly in restore 'C' mode (this will | |
405 | allow not to exhaust the available /tmp space when | |
406 | ccmparing large files). Thanks to Kenneth Porter | |
407 | <shiva@well.com> for the suggestion. | |
408 | ||
409 | Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) | |
410 | ==================================================================== | |
411 | ||
412 | 1. Fixed some several duplicate 'DUMP: DUMP:' in the | |
413 | output of dump. | |
414 | ||
415 | 2. Corrected the estimation of blocks to dump. Note that | |
416 | this is still wrong for large directory inodes, due | |
417 | to the size of a BSD directory entry on the tape | |
418 | (estimation is based on the size of the ext2 directory, | |
419 | which is smaller because it doesn't contain the null | |
420 | character at the end). | |
421 | ||
422 | 3. Made dump report the total number of MB written to | |
423 | tape at the end of run. Thanks to W. Reilly Cooley | |
424 | <wcooley@nakedape.cc> for the patch. | |
425 | ||
426 | 4. Added the -X option to restore giving the possibility | |
427 | to read the names of the files to be extracted/listed | |
428 | from a text file (in addition of the command line). | |
429 | Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the | |
430 | patch. | |
431 | ||
432 | 5. Added the device name and the current volume number | |
433 | as arguments to the end of tape script (dump -F option). | |
434 | ||
435 | 6. Made the multi-volume dump work again (after having | |
436 | broken it in 0.4b15). | |
437 | ||
438 | Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) | |
439 | =================================================================== | |

441 | 1. Added a prompt command in interactive restore mode. Thanks | |
442 | to Andreas Dilger <adilger@home.com> for the patch. | |
443 | ||
444 | 2. Fixed a buffer overflow problem in dump (caused by | |
445 | not checking the size of the filesystem parameter). | |
446 | Thanks to Kim Yong-jun <loveyou@hackerslab.org> for | |
447 | reporting this on Bugtraq (and to several dump users | |
448 | who forwarded me his mail). | |
449 | ||
450 | 3. Added the '-F script' option to dump in order to | |
451 | launch a script at the end of each tape (to be used | |
452 | with a tape changer, or to notify the sysadmin by | |
453 | pager etc.). | |
454 | ||
455 | 4. Fixed a bug in restore compare code caused by the changes | |
456 | I made in 0.4b14. | |
457 | ||
458 | 5. Fixed the treatment of options using the old BSD syntax | |
459 | in both dump and restore. | |
460 | ||
461 | Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) | |
462 | ======================================================================= | |
463 | ||
464 | 1. Fixed a bug in dump which may have caused invalid deleted | |
465 | directories to be dumped out if they were deleted after the | |
466 | mapping pass. This could occure on active filesystem and lead | |
467 | to heap corruption (causing dump malfunction in many possible ways). | |
468 | Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this | |
469 | bug and submitting the patch. | |
470 | ||
471 | 2. Fixed the handling of the filesystem parameter in dump. A | |
472 | '/mnt/disk' parameter caused the disk contents to be dumped, | |
473 | but a '/mnt/disk/' parameter caused the mountpoint directory | |
474 | to be dumped (generally an empty directory). | |
475 | ||
476 | 3. Improved the output of dump in order to tell which directory | |
477 | it is currently dumping (when dumping a subtree). | |
478 | ||
479 | 4. Added the '-e' exclude inode option to dump. Thanks to | |
480 | Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch. | |
481 | ||
482 | 5. Added a REPORTING-BUGS file in order to provide a guide | |
483 | on how to correctly report a bug in dump/restore. | |
484 | ||
485 | 6. Fixed a restore problem when restoring a hard link to an inode | |
486 | having the immutable or append-only attribute set. Thanks to | |
487 | Ambrose Li <acli@mingpaoxpress.com> for submitting the patch. | |
488 | ||
489 | 7. Fixed a compatibility problem between dumps made on little | |
490 | endian machines (the format was correct) and big endian | |
491 | machines (the format was incorrect). This fix break the | |
492 | compatibility with the older dumps made on big endian | |
493 | machines (sparc, m86k, ppc etc). For the first time in | |
494 | linux dump's history (I believe), the dumps made by *BSD, | |
495 | Linux/alpha, Linux/sparc and Linux/x86 are compatible, | |
496 | so interchangeable. Thanks to Rob Cermak | |
497 | <cermak@ahab.rutgers.edu> for submitting the bug and | |
498 | helping me test the fix. | |
499 | ||
500 | 8. Fixed the way dump reports the remaining percent/time, if | |
501 | the number of blocks actually dumped exceeds the estimated | |
502 | number of blocks. Thanks to Jean-Paul van der Jagt | |
503 | <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug. | |
504 | ||
505 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) | |
506 | ====================================================================== | |
507 | ||
508 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
509 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
510 | ||
511 | 2. Removed the requirement to build the RPM as root from the | |
512 | spec file. Thanks to Christian Weisgerber | |
513 | <naddy@mips.rhein-neckar.de> for submitting this. | |
514 | ||
515 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, | |
516 | causing dump to block when dumping really huge filesystems. | |
517 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
518 | helping me find this bug. | |
519 | ||
520 | 4. Fixed the treatment for an interrupt signal when dump access | |
521 | the remote tape through RSH. Thanks to Christian Weisgerber | |
522 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
523 | ||
524 | 5. Fixed a bug which was causing dump/restore to display | |
525 | garbage characters instead of the remote host name. | |
526 | ||
527 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) | |
528 | ===================================================================== | |
529 | ||
530 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
531 | <kukuk@suse.de> for submitting the patch. | |
532 | ||
533 | 2. Fix for the exit code when using the size estimate option of | |
534 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
535 | submitting the patch. | |
536 | ||
537 | 3. Handle EINTR in atomical reads/writes in dump, which was causing | |
538 | dump to fail on some systems. Thanks to Eric Jergensen | |
539 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
540 | ||
541 | 4. Handle more than 16 characters for the device names in dumpdates. | |
542 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
543 | tracking down the problem and proposing the solution. | |
544 | ||
545 | 5. Fixed a bug in dump which prevented the creation of the | |
546 | dumpdates file when doing a 0-level dump without already | |
547 | having a dumpdates file. Thanks to Patrik Schindler | |
548 | <poc@pocnet.net> for reporting the bug. | |
549 | ||
550 | 6. Changed the way dump 'S' flag reports the size estimate | |
551 | from number of blocks into bytes (making it compatible | |
552 | with the Solaris version, and simplifying things for | |
553 | amanda users). Thanks to Jason L Tibbitts III | |
554 | <tibbs@math.uh.edu> for reporting the bug. | |
555 | ||
556 | 7. Fixed a compatibility problem in linux/alpha dump tape format. | |
557 | Now the linux/alpha dump are (again) compatible with the | |
558 | other dump formats. But this breaks compatibility with | |
559 | older dumps made on alpha. Thanks to Mike Tibor | |
560 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
561 | ||
562 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) | |
563 | ====================================================================== | |
564 | ||
565 | 1. Added a '--enable-kerberos' to configure. | |
566 | ||
567 | 2. Added a 'S' option to dump which determines the amount of space | |
568 | that is needed to perform the dump without actually doing it, similar | |
569 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak | |
570 | <cermak@ahab.rutgers.edu>. | |
571 | ||
572 | 3. Added a 'M' multi-volume option to dump and restore which enables | |
573 | dumping to multiple files (useful when dumping to an ext2 | |
574 | partition to make several dump files in order to bypass the 2GB | |
575 | file size limitation). The 'f' argument is treated as a prefix and | |
576 | the output files will be named <prefix>001, <prefix>002 etc. With | |
577 | the 'M' flag, restore automatically selects the right file without | |
578 | asking to enter a new tape each time. | |
579 | ||
580 | 4. Fixed a memory leak which was causing dump to grow very big | |
581 | (270MB when dumping a 10GB filesystem...). Thanks to Jason | |
582 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
583 | ||
584 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) | |
585 | ====================================================================== | |
586 | ||
587 | 1. Make configure test if the system glob routines support | |
588 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
589 | routines instead of system ones. Thanks to Bernhard Sadlowski | |
590 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
591 | and helping me resolve this and other minor libc5 compiling | |
592 | glitches. | |
593 | ||
594 | 2. Fix a problem when dumping a ext2fs with the 'filetype' | |
595 | feature enabled. Thanks to Patrick J. LoPresti | |
596 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
597 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
598 | ||
599 | 3. Made the nodump flag work on directories. A directory which | |
600 | has the nodump flag gets never dumped, regardless of its | |
601 | contents. | |
602 | ||
603 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> | |
604 | which allows dump on an active ext3 filesystem. However, this | |
605 | is a "quick and dirty" patch which enables backup of an ext3 | |
606 | filesystem through the ext2 compatibility (by ignoring the | |
607 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
608 | it is dumped (it should not). | |
609 | ||
610 | 5. Test the superblock compatibility flags when dumping, in order | |
611 | to be sure that we know how to deal with specific features. | |
612 | ||
613 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) | |
614 | ==================================================================== | |
615 | ||
616 | 1. Use lchown instead of chown, fixing a possible security problem | |
617 | when restoring symlinks (a malicious user could use this | |
618 | to deliberately corrupt the ownership of important system files). | |
619 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
620 | this and providing the patch. | |
621 | ||
622 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) | |
623 | ==================================================================== | |
624 | ||
625 | 1. Put dump sources under CVS, added Id tags in all files so | |
626 | one can use 'ident' on binary files. | |
627 | ||
628 | 2. Added the dump/restore version in the usage text so one can | |
629 | easily verify the version he is using. | |
630 | ||
631 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes | |
632 | a va_start/va_end problem on linux-ppc (always call va_start | |
633 | va_end in pairs each time we use a vararg function). | |
634 | ||
635 | 4. Added again the DT_* constants because old libc does not | |
636 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
637 | for submitting the bug report. | |
638 | ||
639 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs | |
640 | this should enable dumping big (huge) filesystems. | |
641 | ||
642 | 6. Added the RSH environment variable in order to be able to | |
643 | use a rsh replacement like ssh when doing remote backups (and | |
644 | bypass the security limitations of rcmd). Now you can do remote | |
645 | backups without being root (or making dump setuid root). | |
646 | ||
647 | 7. Modified again the way dumpdates works. For incremental dumps, | |
648 | we need to read dumpdates even if we are not using 'u' option. | |
649 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
650 | this should work. | |
651 | ||
652 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) | |
653 | =================================================================== | |
654 | ||
655 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
656 | was not compiled in. | |
657 | ||
658 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
659 | to them (fsetflags takes a char*, setflags an open fd!). | |
660 | ||
661 | 3. (f)setflags is called only if the flags aren't empty. If the | |
662 | file is a special file, a warning is printed, because changing | |
663 | flags implies opening the device. Normally, a special file | |
664 | should not have any flag... (Debian bug #29775, patch provided | |
665 | by Abhijit Dasgupta <abhijit@ans.net>). | |
666 | ||
667 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
668 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
669 | ||
670 | 5. Changed the default behaviour to not create dumpdates | |
671 | unless 'u' option is specified. Removed the old "debian-patch" | |
672 | which provided the same thing. (Debian bug #38136, #33818). | |
673 | ||
674 | 6. Removed all those dump*announce, since they were getting old... | |
675 | ||
676 | 7. Added warning messages if dumpdates does not exist and | |
677 | when an inferior level dump does not exist (except for a level 0 | |
678 | dump). | |
679 | ||
680 | 8. Debugged the glob calls in interactive mode: restore used a | |
681 | dirent struct which was different from the /usr/include/dirent.h | |
682 | one (this used to work, is it a glibc2 change?), so none of the | |
683 | compat glob (which used /usr/include/dirent.h) or the system glob | |
684 | worked. Restore use now the system dirent (and the system | |
685 | DT_* constants), which are compatible with BSD ones. | |
686 | ||
687 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
688 | the location of dumpdates file. By default, it is | |
689 | /etc/dumpdates. | |
690 | ||
691 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
692 | included the current date/version in man pages. | |
693 | ||
694 | 11. Corrected the estimation of remaining time when | |
695 | the operator doesn't change the tapes quickly enough. This | |
696 | was an old bug, I thought I corrected it, and discovered | |
697 | that in fact it was corrected in two different places, so | |
698 | the results canceled each other... | |
699 | ||
700 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
701 | =================================================================== | |
702 | ||
703 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
704 | ||
705 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
706 | isn't specified. | |
707 | - several fixes in the man pages. | |
708 | - update the default tape device to /dev/st0. | |
709 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
710 | - buffer overruns. | |
711 | - use environment variable for TMPDIR (instead of /tmp). | |
712 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
713 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
714 | - wire $(OPT) throughout Makefile's. | |
715 | ||
716 | 2. Upgrade the dump revision to 1, making possible to dump filesystems | |
717 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
718 | ||
719 | 3. Fix some compile warnings, prototype all functions. | |
720 | ||
721 | 4. Use glibc err/glob instead of internal compatibility | |
722 | routines (only if available). | |
723 | ||
724 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided | |
725 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
726 | ||
727 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
728 | ====================================================================== | |
729 | ||
730 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
731 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
732 | tape length calculation" flag, dump/restore can use kerberos now | |
733 | (this is NOT tested), use environment variables for TAPE and | |
734 | RMT etc.). | |
735 | ||
736 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
737 | ||
738 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
739 | tapes (files splited accros two tapes give "size changed" errors | |
740 | when comparing). | |
741 | ||
742 | 4. Corrected the long standing bug when dumping multiple tapes. | |
743 | This works for me, needs further testing. | |
744 | ||
745 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) | |
746 | ==================================================================== | |
747 | ||
748 | 1. Dump now runs correctly on kernels 2.1.x | |
749 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
750 | ||
751 | Changes between versions 0.4b2 and 0.4b3 | |
752 | ======================================== | |
753 | ||
754 | 1. Use realpath() if available | |
755 | ||
756 | 2. Report statistics | |
757 | ||
758 | Changes between versions 0.4b1 and 0.4b2 | |
759 | ======================================== | |
760 | ||
761 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
762 | the patch) | |
763 | ||
764 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
765 | ||
766 | 3. Fixed configure.in to correctly handle --enable-rmt | |
767 | ||
768 | Changes between versions 0.3 and 0.4b1 | |
769 | ====================================== | |
770 | ||
771 | 1. Integrated the changes from 4.4BSD-Lite2 | |
772 | ||
773 | 2. Integrated the patches from Debian and Red Hat | |
774 | ||
775 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
776 | ||
777 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
778 | should solve the endianness problem on SparcLinux. | |
779 | ||
780 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
781 | distribution's one) to use autoconf | |
782 | ||
783 | 6. Fixed a few minor bugs | |
784 | ||
785 | Changes between versions 0.2e and 0.2f | |
786 | ====================================== | |
787 | ||
788 | 1. Added the creation of named pipes (fifos) in restore. | |
789 | ||
790 | 2. Added the -N flag in the restore manual page. | |
791 | ||
792 | 3. Added the file kernel.patch which contains the llseek() optimization | |
793 | patch for 1.2.x kernels. | |
794 | ||
795 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
796 | not restored. | |
797 | ||
798 | 5. Integrated some changes from FreeBSD 2.2. | |
799 | ||
800 | 6. Added a call to ftruncate() after restoring each file to restore | |
801 | correctly files ending by a hole. | |
802 | ||
803 | Changes between versions 0.2d and 0.2e | |
804 | ====================================== | |
805 | ||
806 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
807 | with owner = root (0) and group = root/wheel/whatever (0). | |
808 | ||
809 | Changes between versions 0.2c and 0.2d | |
810 | ====================================== | |
811 | ||
812 | 1. Dump is now able to backup 2GB+ filesystems. | |
813 | ||
814 | 2. Dump and restore can now be linked as static binaries. | |
815 | ||
816 | Changes between versions 0.2b and 0.2c | |
817 | ====================================== | |
818 | ||
819 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
820 | ||
821 | Changes between versions 0.2a and 0.2b | |
822 | ====================================== | |
823 | ||
824 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
825 | ||
826 | 2. Enabled optimization again. | |
827 | ||
828 | Changes between versions 0.2 and 0.2a | |
829 | ===================================== | |
830 | ||
831 | 1. Disabled the optimization during compilation. | |
832 | ||
833 | Changes between versions 0.1 and 0.2 | |
834 | ==================================== | |
835 | ||
836 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
837 | the fs_type field (actually, I modified the file fstab.c to make it | |
838 | use the mntent functions). | |
839 | ||
840 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
841 | made by dump should be readable by the BSD restore and backups made | |
842 | by the BSD dump should be readable by restore. Unfortunately, this | |
843 | means that the dump format has changed between version 0.1 and version | |
844 | 0.2 :-( | |
845 | ||
846 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
847 | filesystems like the BSD version. | |
848 | ||
849 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
850 | than 2 GB. | |
851 | ||
852 | Changes between versions 0.0 and 0.1 | |
853 | ==================================== | |
854 | ||
855 | 1. Now create links rdump and rrestore during the `make install' step. | |
856 | ||
857 | 2. Linux port specific bugs added to the manual pages | |
858 | ||
859 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
860 | incremental backups. | |
861 | ||
862 | 4. Better ls-like format in restore in interactive mode. |
