Fixed dump compilation with old gcc versions. Thanks to + Mike Castle for the patch. + +2. Fixed some warnings (howmany, roundup, powerof2 redefined) + when compiling against a recent glibc version. + +3. Fixed a bug in restore preventing the read of a dump tape + written with Solaris 7 ufsdump. Thanks to Patrick Higgins + for reporting the bug and providing + the test case. + +4. Changed dump to enable the creation of volumes of different + sizes in a single run (make -B accept a list of values). + Patch contributed by Florian Zumbiehl . + +5. Use the glibc provided minor() and major() macros instead + of our own bitmask implementation. This should be safe for + when the major/minor namespace will migrate to 32 bits. + Thanks to Zhang Jun for reporting + the bug. + +6. Made explicit in the dump man page that dump will not create + a remote file, it will only write to an already existing one. + +7. Another try at making size estimates better again. + +8. Put back the inconditional running of the end-of-tape + script which was changed in 0.434 to be run only when -M + or multiple -f were NOT specified. Some users rely on this + feature even when it is combined with -M/-f. + +9. Fixed restore when restoring huge backups (where rstdir... + temporary files are over 2GB). Thanks to + Raphael Jaffey for reporting this, + debugging the issue and making the patch. + +10. Made restore understand FreeBSD UFS2 tapes. Thanks to + David for submitting the bug + and providing a test case. + +11. Made dump work with an arbitrary integer level (no more 10 + levels only limitation). Thanks to Matthew + for the patch. + +Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003) +======================================================================= + +1. Added a note in the dump man page saying that the default + blocksize can be 32 if -d is used with a high density argument. + Thanks to Antonios Christofides + for the patch. + +2. Fixed configure to correctly understand CPPFLAGS, CFLAGS, + LDFLAGS environment variables. Thanks to Arcady Genkin + for reporting the bug. + +3. Made -e/-E options of dump accept an unlimited number of inodes + to be excluded, rather than a hardcoded maximum. Thanks to + Dietrich Rothe for the patch. + +4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE + and -D_USE_BSD_SIGNAL defines in configure in order to solve + 64bit build problems because quad_t is redifined with a + different signature. Thanks to Mike Harris + for reporting this bug. + +5. Made restore build on Solaris, making possible to + restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke + for the patch. + +6. Made an extension in the dump tape format capable of saving + MacOSX specific inode extensions. Uwe Gohlke + wrote the extension and contributed the restore code back + into this codebase. The same extension mechanism will be + used in the future to save ACLs... + +7. Made rmt work correctly with regard to QFA and local/remote + files and tapes. The remote access will however work only + when the dump provided rmt version is used. If you want to + use another rmt server, please do not use the QFA feature. + Thanks to Uwe Gohlke for the patch. + +Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003) +==================================================================== + +1. Fixed the INSTALL file to reflect the actual install paths. + Thanks to David Ronis for + reporting the bug. + +2. Fixed the configure script to only check for headers presence + instead of trying to compile them. This should fix issues + with old build environments. Thanks to Kari Lempiainen + for reporting the bug. + +3. Fixed restore to correctly ignore sockets when comparing + a dump (as socket cannot be properly restored anyway). Thanks + to Gunther Reiszig for reporting the bug. + +4. Fixed restore to correctly access the archive file (-A argument) + even when using a remote tape. Thanks to Fabrice Bellet + for reporting the bug. + +5. Fixed (again) handling of long (largefile) seeks in rmt. + Thanks to Fabrice Bellet for reporting + the bug. + +6. Fixed restore corner case when dealing with large block sizes + dump is able to write now (-b 1024). Thanks to Fabrice Bellet + for reporting the bug. + +7. Fixed a bug preventing dump to access a filesystem having + a label exactly 16 bytes in length. Thanks to + for reporting the bug. + +8. Made dump store dump dates using explicit timezones, fixing a + problem with incremental dumps if the timezone is modified + between the dumps. Thanks to Philippe Troin for + the bug report and the patch. + +9. Fixed a bug encountered when dumping individual files (not full + filesystems or directories) and dangling symbolic links happen + to be in the list of files. For as far as dump is concerned, + dangling symbolic links are allowed, and are dumped as is. + Thanks to Jin-su Ahn for reporting the + bug and providing the fix. + +10. Fixed open and creation modes and permissions for QFA and + table-of-contents files in dump and restore. Thanks to + Philippe Troin for the patch. + +11. Fixed the archive file descriptor handling enabling it to be 0. + This can happen in some cases when shell redirections are used. + Thanks to Philippe Troin for the patch. + +12. Delayed the opening of archive file until after suid had been + dropped (fixing a possible security issue if dump is suid). + Thanks to Philippe Troin for the patch. + +13. Fixed the 'S' command handling in the rmt client part. + Thanks to Philippe Troin for the patch. + +14. Modified the end-of-tape script handling to print out statistics + (and stop the timer) before launching the eot script. Also, the eot + script does not get run anymore when using -M (which makes sense) or + when multiple tapes are listed on the command line + (-f tape0,tape1,tapen) (which also makes sense). + Thanks to Philippe Troin for the patch. + +15. Relicensed dump/restore under the 'revised' BSD license, as per + ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change. + +16. Added LZO compression to dump. This new compression method has + the advantage of being super fast, thus not killing tape streaming + on slow machines. Thanks to Helmut Jarausch + for the patch and to + Markus Oberhumer for giving special permission + to include his miniLZO project (GPL licensed) in dump/restore. + +17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia + for reporting the bugs. + +18. Added a special rmt version which can do encryption when writing + to tape. Read examples/encrypted_rmt/README for details on + how to enable and configure it. Thanks to Ken Lalonde + for the patch. + +19. Made dump work with 2.5 kernel end of tape early warning semantics. + Thanks to Kai Makisara for the patch. + +20. Fixed a bug which caused dump -w|-W not to work anymore, because + the fs_freq and fs_passno fields in /etc/mtab are always set + to 0 0. Thanks to Trent Piepho for + reporting the bug. + +Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003) +======================================================================= + +1. Added a note in the restore man page clarifying the question + 'set the permissions on the current directory ?' asked by + restore at the end of treatment in -i and -x modes. + +2. Fixed the endianess issues when reading compressed tapes. + Thanks to Dark Force for + reporting this bug and providing test cases. + +3. Fixed the "ACL won't be dumped" warning message (which showed + an extra, unrelated error message). Thanks to Dragan Krnic + for reporting this bug. + +4. Made dump look first into /etc/mtab, then into /etc/fstab + when searching for filesystem paths. Also fixed some problems + caused by binding mounts or multiple block device mounts. + Thanks to Matus Uhlar , Elliott Mitchell + , Greg Edwards , + Brian Hoy . (fixes Debian bugs #147086 + and #160305, Sourceforge bugs #618699 and #679832). + +5. Made dump's -I option accept the value '0' meaning all the + read errors will be ignored. This can be useful when running + dump from unattended sessions (like cron jobs). Thanks to + John I Wang for the suggestion. + +6. Fixed the output of dump to indicate 'blocks' instead of + 'tape blocks' in the various messages (blocks are always + 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and + made it clearly print the current blocksize at the start of + a dump. Thanks to Michal Szymanski for + the suggestions. + +7. Made rmt understand long (largefiles) seeks. + +8. Fixed build with very old versions of libext2fs, where + EXT2_FT_* constants were undefined. + +9. Made dump accept the dumpdates path on the command line + (-D file option) instead of using only the hardcoded one. + Thanks to Piete Brooks for the + suggestion. + +10. Enabled rmt, LFS, readline, QFA options by default in + ./configure. Updated the configure process (new versions + of config.guess, config.sub etc). + +Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002) +======================================================================= + +1. Changed dump to use fcntl(F_SETLK) style locking instead + of flock() when locking the dumpdates file. With the old + locking scheme, a local user having read rights on the + dumpdates file could be able to do a Denial of Service attack + on dump. In order to lock the dumpdates file with the new + scheme, the user would need to have write access on the file. + Thanks to Richard Johnson for + reporting the bug (originally a bugtraq post). + +2. Fixed interactive 'ls' which caused spurious errors warnings + about 'undefined filetypes' detected. Thanks to Jorgen Ostling + for reporting this + bug. + +3. Fixed dump's estimate when dealing with sparse inodes. + +4. Modified dump to allow setting a blocksize bigger than 32kB + (raised the limit to 1024kB), because newer hardware needs + this for proper operation. Thanks to Dirk Traenapp + for reporting this. + +5. Fixed a bug causing Dump to stop and report an error if an + inode number in the exclude file was followed by some amount + of whitespace. Thanks to Jeffrey Sofferin + for reporting this bug. + +6. Fixed a bug which caused restore, in some particular cases, + to ask some 'scary' questions and leave a bunch of RSTTMP + directories behind when restoring incremental tapes. Thanks + to Philippe Troin for reporting this bug and + providing the test cases. + +7. Changed the wording when inodes are excluded from dump: + replaced 'Added inode 7 to exclude list' with + 'Excluding inode 7 (resize inode) from dump', as suggested + by Elliott Mitchell in a Debian bug report. + +Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002) +=================================================================== + +1. Fixed rmt open flags transmission (GNU's symbolic syntax over + rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi + for reporting the bug. + +Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002) +=================================================================== + +1. Made dump print out the ext2 logical block number in case of a read + error, which can be given as an argument to debugfs' ncheck command, + in order to find out the affected inode. Added note about this + usage in dump's man page. + +2. Fixed a problem in restore when reading tapes written on big + endian machines with very old versions of dump. The patch was + contributed by George Helffrich . + +3. Fixed the tape length calculation when using large tapes + and compression. Thanks to Georg Lippold + for reporting the bug. + +4. Added a new set of examples in dump_on_cd_2 directory, based + on dump_on_cd examples but somewhat enhanced, supporting DVD + media, and localized in english and german. Thanks to + Georg Lippold for the new scripts. + +5. Made dump save 32 bit UID/GID. Internally, this was achieved + by switching from the old BSD inode format to the new BSD + inode format, which means that the tape format was changed. + However, since all restore versions out there should + transparently support both inode formats, the change should + have no side effects. Thanks to John Yu for + reporting the bug. + +6. Fixed a lot of warnings in the code shown when compiling + with 'gcc -W'. Thanks to Matthias Andree + for reporting this. + +7. Fixed a small markup bug in the dump man page. Thanks to + Eric S. Raymond for submitting the + patch. + +8. Rewrote entirely the man pages using the tmac.an macro + package (Linux man page format) instead of the original BSD + format. They should be now cleaner and easier to modify. + +Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002) +================================================================== + +1. Fixed a problem in the rmt ioctl command, where ioctl's issued from + non Linux clients were misinterpreted. The description of the problem + (incompatible numbering in Linux mtio opcodes) is documented at + ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to + Jörg Schilling for reporting this bug and + providing an excellent, cross-platform replacement for rmt in his + star package. + +2. Fixed a bug reported by Andy Mentges + which caused restore to fail when the inode maps were not entirely + contained on the first volume (when using really small volumes or + when dumping a huge number of inodes). + +3. Fixed a problem in dump, where files in subdirectories of directories + that have the nodump flag set (or being excluded with -e/-E) were + sometimes incorrectly dumped (instead of being excluded). The original + fix is from David C Lawrence in the FreeBSD version + of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414 + Thanks to Ted Grzesik for reporting the bug and + help testing the patch. + +4. Added some example scripts from Gerd Bavendiek + which makes one able to pipe the output of dump, by the net, to + a remote CD-burner server. + +5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt), + and use GNU's symbolic syntax over rmt instead of numerical values + to assure multiple platform compatibility. + +6. Documented the -d option in restore. + +7. Added a -v (verbose) mode to dump. For now it just prints the number + of the inode being dumped, but this could evolve in future versions + to include interesting debugging output. + +8. Added a -o flag to restore, which automatically restores the current + directory permissions in -i or -x mode, without asking the operator + whether to do so. Patch submitted by Tony Clayton + and Peter Samuel . + +Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002) +==================================================================== + +1. Fixed a bug in the QFA feature which could have caused + a bad tape positionning on restore (causing extra delays in + restore). Credits go to Uwe Gohlke . + +2. Added a small note in the dump man page specifying that + there should be no white space between the option letter and + the -j or -z parameter, thanks to Kenneth Porter + +3. Made restore work with older versions of the readline library, + by checking in configure for several extended symbols. Restore + can now be compiled with a readline as old as the 2.0 release + (though it may be a good idea to upgrade it to a more recent + version...). Thanks to Andrew Donkin for + reporting the build failures. + +4. Fixed a performance problem with the QFA file creation in + dump, which made unnecessary seeks on the tape slowing down + the dump. Thanks to Andrew Donkin for + reporting this issue. + +5. Removed the inclusion of some kernel headers in the dump + source, which prevented the compile in some kernel/glibc + headers/architecture combination. Thanks to Bdale Garbee + for reporting the bug. + +6. Added the appropriate error message when dump fails to + open the output file for writing. Thanks to Amith Varghese + for reporting this bug. + +7. Made restore able to understand large Solaris ufsdump tapes + (containing inodes bigger than 4194304). Sun have introduced + an "extension" to the dump tape format when dealing with + those inodes, which was uncorrectly handled by Linux restore. + Thanks to Uwe Gohlke for reporting the bug and + providing a test case. + +8. Added the -m parameter to dump which optimises the output for + inodes having been changed but not modified since the last dump + ('changed' and 'modified' have the meaning defined in stat(2)). + For those inodes, dump will save only the metadata, instead of + saving the entire inode contents. Inodes which are either + directories or have been modified since the last dump are saved + in a regular way. Uses of this flag must be consistent, meaning + that either every dump in an incremental dump set have the flag, + or no one has it. + +Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002) +======================================================================= 1. Fixed behaviour of dump when exceeding resource limits (SIGXFSZ treatment). @@ -32,6 +438,18 @@ Changes between versions 0.4b26 and 0.4b27 (released ???????????????) 7.
