$Id: CHANGES,v 1.282 2006/01/02 15:24:22 stelian Exp $

Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
=====================================================================

1.	Fix restore of dumped Access Control Lists. The previous
	code for EA works fine, but ACLs needed conversion from the
	ext2/3 disk format to posix_acl format before restoring.

2.	Fix some issues with restoration of EA on big endian
	platforms.

3.	Fix restore when the symtab is over 2GB in size.

4.	Made the directory hash indexing an optional feature,
	accessible by the '-H' option of restore, and disable it
	by default.

5.	Fixed dump to not include extended attributes information
	in the toc (archive) file which confused restore -t.

Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
=================================================================

1.	Changed restore to emit warnings (instead of emitting a fatal
	error) if a file (or a directory) is unavailable for a 
	comparision (if the user doesn't have the necessary permissions
	to access it for example). Thanks to Kenneth Porter
	<shiva@sewingwitch.com> for the bug report.

2.	Re-done the 'do not save directory entries to non-dumped inodes
	(excluded from dump)' feature. The previous implementation
	worked well for excluded directories but not for regular files.
	Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
	report.

3.	Fixed a bug in dump where the tape size was miscalculated when
	the user used -d/-s to specify the tape characteristics. Thanks
	to Philip Goisman <goisman@physics.arizona.edu> for reporting
	the bug.

4.	Fixed another bug introduced in restore with the hashtree
	implementation. This one caused restore to stop saying
	"removenode: non-empty directory" in some cases.

5.	Added support for dumping and restoring ext2/3 extended
	attributes (EA), like the access control lists (ACL) or
	the security labels used by SELinux.

Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
======================================================================

1.	The newly added dump_on_cd_3 example was buggy, replace it
	with an updated version from Andrew Basterfield
	<bob@cemetery.homeunix.org>.

2.	Made restore to chdir() back into the initial directory when
	dumping core while aborting a comparision operation. The
	previous behaviour was to write the corefile at the root of
	the directory being compared, which could very well be 
	read only and preventing the corefile generation. Thanks
	to Kenneth Porter <shiva@sewingwitch.com> for the bug report.

3.	Silenced the failure to call fgetflags() when comparing an
	entry which has no ext2 attributes (as in lsattr()).

4.	Fix a brown paper bug in restore -C which broke restore and
	caused modifications on the filesystem being compared
	(directories containing a file with the same name as the
	directory get renamed to RSTTMP...). Thanks to Kenneth Porter
	<shiva@sewingwitch.com> for finding the bug and helping me
	reproduce it.

5.	Made restore -C force the -N flag (no writing allowed on
	the disk) in order to prevent more bugs like the above one.

Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
=====================================================================

1.	Fix a couple of troff syntax bugs in the man pages.
	Thanks to Eric Raymond <esr@thyrsus.com> for the patch.

2.	Made restore use either libncurses or libtermcap, depending
	on which one is available at configure time.

3.	Fixed restore negative size display bug when comparing a
	dump containing files over 2GB. Thanks to Steve Bonds
	<sbonds@users.sourceforge.net> for the bug report.

4.	Do not save directory entries to non-dumped inodes 
	(excluded from dump). This will eliminate the 'missing
	file' warnings when doing 'restore -C'.

5.	Fix dump crash when backuping a huge (2TB) filesystem,
	due to a bogus calculation on the inode map size.
	Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for 
	submitting the bug and testing the fix.

6.	Fix a problem in restore where the final \0 in the symbolic
	link names could have been lost, generating corrupt filenames.
	Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
	bug.

7.	Implemented a hash list for the directory names in restore.
	The linear list used before caused problems in interactive
	restores when dealing with directories having thousands of
	entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
	for reporting the bug.

8.	Improved restore -C, this time including the directory
	attributes into the comparision.

9.	Made restore understand tapes containing EA/ACLs (which will
	be dumped by the next version of dump). In this version 
	extended attributes on the tape are ignored, for full EA/ACL
	support wait for the next version or try the experimental EA
	patch.

Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
==================================================================

1.	Added the --enable-staticz configure option which enables
	dump and restore to be linked with static versions of
	libz and libbz2 (and dynamic versions of all other libraries).
	This will make Debian users happy, because libz and libbz2
	were the only needed libraries living in /usr, all the
	others live in /lib. In case of system emergency, it is 
	better not to have to rely on an extra filesystem.
	Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.

2.	Fix compilation on (at least the Linux Debian port to) AMD64.
	(<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
	that are also defined by <linux/types.h> (<asm/types.h>) and 
	they conflict).

3.	Make dump's reading of the dumpdates file a bit more robust,
	preventing dump from crashing when the dumpdates file has
	been modified by hand.

4.	Fixed some offset calculations in dump code which could 
	lead to "bread lseek errors" on large filesystems. Thanks
	to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
	reporting this bug and debugging the issue.

5.	Made dump use the blkid library when searching for devices
	by label or uuid instead of dump's own routines.

6.	Corrected a bug in dump where a wrong LABEL=... line in
	/etc/fstab could prevent dump from dumping unrelated 
	filesystems. Thanks to Bruce Lowekamp
	<lowekamp@users.sourceforge.net> for reporting the bug.

Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
====================================================================

1.	Fixed dump compilation with old gcc versions. Thanks to
	Mike Castle <dalgoda@users.sourceforge.net> 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
	<phiggins@transzap.com> 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 <florz@gmx.de>.

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 <zhangjun@nanjing-fnst.com> 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 <rjaffey@artic.edu> for reporting this, 
	debugging the issue and making the patch.

10.	Made restore understand FreeBSD UFS2 tapes. Thanks to
	David <vrtin@users.sourceforge.net> 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
	<msvincen@midway.uchicago.edu> 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 <A.Christofides@itia.ntua.gr>
	for the patch.

2.	Fixed configure to correctly understand CPPFLAGS, CFLAGS,
	LDFLAGS environment variables. Thanks to Arcady Genkin
	<antipode@users.sourceforge.net> 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 <d-rothe@users.sourceforge.net> 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 <mharris@redhat.com>
	for reporting this bug.

5.	Made restore build on Solaris, making possible to
	restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
	<uwe@ugsoft.de> for the patch.

6.	Made an extension in the dump tape format capable of saving
	MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
	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 <uwe@ugsoft.de> 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 <ronis@ronispc.chem.mcgill.ca> 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 
	<kari@funky.pp.fi> 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 <gunther@mit.edu> 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 
	<fabrice@bellet.info> for reporting the bug.

5.	Fixed (again) handling of long (largefile) seeks in rmt.
	Thanks to Fabrice Bellet <fabrice@bellet.info> 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
	<fabrice@bellet.info> for reporting the bug.

7.	Fixed a bug preventing dump to access a filesystem having 
	a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
	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 <phil@fifi.org> 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 <jsahn@ee.snu.ac.kr> 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 <phil@fifi.org> 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 <phil@fifi.org> 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 <phil@fifi.org> for the patch.

13.	Fixed the 'S' command handling in the rmt client part.
	Thanks to Philippe Troin <phil@fifi.org> 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 <phil@fifi.org> 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 
	<jarausch@igpm.rwth-aachen.de> for the patch and to 
	Markus Oberhumer <markus@oberhumer.com> 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
	<ant@notatla.demon.co.uk> 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
	<ken@globalremit.com> for the patch.

19.	Made dump work with 2.5 kernel end of tape early warning semantics.
	Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> 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 <xyzzy@speakeasy.org> 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 <daq4th@users.sourceforge.net> 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
	<dkrnic@lycos.com> 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 <uhlar@fantomas.sk>, Elliott Mitchell
	<ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
	Brian Hoy <brian.hoy@opus.co.nz>. (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 <jiwang@users.sourceforge.net> 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 <msz@astrouw.edu.pl> 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 <pb22@users.sourceforge.net> 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 <Richard.Johnson3@ey.com> 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 
	<jorgen_ostling@users.sourceforge.net> 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
	<dtraenapp@users.sourceforge.net> 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 
	<sofferin@users.sourceforge.net> 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 <phil@fifi.org> 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 <ehem@m5p.com> 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
	<eros@lamel.bo.cnr.it> 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 <george@geology.bristol.ac.uk>.

3.	Fixed the tape length calculation when using large tapes
	and compression. Thanks to Georg Lippold 
	<g_lippold@sourceforge.net> 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 <g_lippold@sourceforge.net> 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 <jky@cs.bu.edu> for
	reporting the bug.

6.	Fixed a lot of warnings in the code shown when compiling
	with 'gcc -W'. Thanks to Matthias Andree 
	<matthias.andree@stud.uni-dortmund.de> for reporting this.

7.	Fixed a small markup bug in the dump man page. Thanks to
	Eric S. Raymond <esr@minx.thyrsus.com> 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
	J�rg Schilling <schilling@fokus.gmd.de> 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 <amentges@jumpline.com>
	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 <tale@dd.org> in the FreeBSD version 
	of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
	Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and 
	help testing the patch.

4.	Added some example scripts from Gerd Bavendiek <bav@epost.de>
	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 <tonyc@e-smith.com>
	and Peter Samuel <peters@e-smith.com>.

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 <uwe@ugsoft.de>.

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 <shiva@well.com>

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 <ard@waikato.ac.nz> 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 <ard@waikato.ac.nz> 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
	<bdale@gag.com> for reporting the bug.

6.	Added the appropriate error message when dump fails to
	open the output file for writing. Thanks to Amith Varghese
	<amithv@yahoo.com> 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 <uwe@ugsoft.de> 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).

2.	Added the -L flag to restore to allow the user to specify a 
	maximal allowed number of miscompares when using restore
	with the -C option to check the backup.

3.	Detailed the manual entry for the -N option of restore.

4.	Added the -a flag to restore to make able doing unattended
	restores in -i or -x mode (automatically walks through the
	multiple dump volumes).

5.	Extended the QFA mode to work with local files and/or
	remote tapes and files. This way, restore can know in advance
	the tape number and the offset for the inodes to extract and 
	can minimize the extraction time by seeking directly to the 
	good tape/offset.

6.	Added the -A <archive> option to both dump and restore, 
	which makes dump to archive a dump table-of-contents in
	the specified file to be used by restore to determine
	whether a file is in the dump file that is being restored.
	(the archive file syntax is also compatible with the
	Solaris ufsdump generated one).

7.	Small fix in restore making it able to read some (broken ?)
	Solaris ufsdump tapes.

8.	Fixed dump to correctly recognise the root filesystem when using
	ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
	for reporting this bug.

9.	Added the -P <file> option to restore to create a
	Quick File Access file from an already made dump. Patch 
	contributed by Uwe Gohlke <uwe@ugsoft.de>.

10.	Made restore compile and run on Solaris, making it a 
	possible replacement for the standard ufsrestore. Port was
	contributed by Uwe Gohlke <uwe@ugsoft.de>.

Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
=====================================================================

1.	Added a set of backup scripts from Eugenio Diaz
	<getnito@yahoo.com> in the examples section. It features
	automatic (cron based) full and incremental dumping of
	several filesystems on a separate filesystem.

2.	Fixed a off-by-one miscalculation which disabled dumping
	a one letter subdirectory. Thanks to Chris Siebenmann 
	<cks@utcc.utoronto.ca> for reporting the bug.

3.	Fixed several restore bugs occuring when trying to
	restore some missing files on the tape. Thanks to Chris
	Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.

4.	Fixed --with-ldopts configure argument passing, installing from
	a separate object directory, makefile cleanups contributed
	by <splite@purdue.edu>.

5.	Fix a bug which could caused, in some conditions, the highest
	number inode of a filesystem, to not be dumped. Many thanks
	to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
	chase this bug.
	
Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
=======================================================================

1.	Added a mini howto from Patrick Walsh in the examples 
	directory.

2.	Minor man pages syntax corrections. Thanks to
	Chris Danis <screechco@home.com> for reporting the bugs.

3.	Added a script from David B. Peterson <dave@toppledwagon.com>
	to the examples section. It features dumping several
	filesystems to a remote tape drive upon ssh.

4.	Added a patch provided by Richard Jones <rich@annexia.org>
	which allows BRADEMAX (number of read errors tolerated by
	dump) to be adjusted using the -I option.

5.	Fixed a bug which disabled doing "restore -C -f -". Thanks
        to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
	patch.

6.	Add the -l option to restore to specify if, when doing a
        remote restore, the file used to access the backup is a
	regular file (the defaults being a tape drive). Restore needs
	to know this information when reading a remote compressed 
	dump. Previously, this information was autodetected, but
	the autodetection code fails (with ioctl: Inappropriate ioctl 
	for device) when using a non Linux remote box. Thanks to 
	many users and especially to Eros Albertazzi 
	<eros@lamel.bo.cnr.it> for reporting this.

7.	Found a workaroung for the dump deadlock problem (3 childs 
	stuck in pause(), father in read()). The workaround seems
	to work for me and several beta-testers. If it doesn't work
	for you, please report back.

8.	Updated the RPM spec file (BuildPrereq, URL etc).

Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
========================================================================

1.	Fixed the permissions of a newly created QFA file by dump.

2.	Cleaned up the source of dump (the external variables 
	definition was a complete mess, making possible to have
	objects overlap).

3.	Fixed restore to use the full tape volume path when doing
	a compare (since it changes the working directory to the
	filesystem being compared in the process).

4.	Added the -q option to dump which makes dump abort 
	whenever it needs operator attention. It should be
	easier to use dump in scripts with this option.

5.	Detect the use of incompatible options to dump and
	refuse them (like -a and -B options together).

6.	Added bzip2 compression to dump/restore (use option -j level 
	to select it). Note that you will need a restore version
	>= 0.4b24 in order to restore a bzip2 compressed dump.
	The same warning as for the zlib compression applies:
	the tape format of a bzip2 dump is not compatible with the
	original BSD tape format.

7.	Fixed a overflow problem in dump corrupting the dump when
	very large files were encountered. Thanks to Vladimir Nadvornik 
	for the bug report.

8.	Added a ioctl(BLKFLSBUF) in dump which should flush the
	kernel buffer/page cache before starting the dump, helping
	a bit those who use dump on mounted filesystems. Thanks to
	John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
	for this suggestion.

9.	Updated the RPM spec file following the RedHat changes 
	(dynamically linked binaries now in /usr/sbin etc).

10.	Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
	which enables restore to recognise multi volume compressed dumps
	done on CD. Included his scripts for dump (which pipe the dump
	output directly into cdrecord) and restore. There is now 
	possible to to backups to CD on the fly!

Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
===================================================================

1.	Fixed a buffer overflow in restore/tape.c. Patch provided by
	Marcus Meissner (Caldera International Security Dept.).

2.	Implement the Sun rmt extended protocol. Patch submitted
	by Ian Gordon <iangordon@users.sourceforge.net>.

3.	Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of 
	the linux kernel header. This ensures that dump always has the
	latest version of this file. Patch submitted by
	Andreas Dilger <adilger@turbolinux.com>.

4.	Report any filesystem present in either /etc/fstab with a 
	positive passno or /etc/dumpdates in dump -w output.
	Patch submitted by Andreas Dilger <adilger@turbolinux.com>.

5.	Fixed the looping problem in dump introduced in the 
	previous version.

6.	Changed the -B option of dump to limit the size of 
	_compressed_ output per volume if compression is on.
	Patch contributed by Helmut Jarausch 
	<jarausch@igpm.rwth-aachen.de>. Note however that, since
	it is impossible to predict the size of the compressed
	data before doing the compression, the -B limit is a bit
	conservative.

7.	Fixed a bug in reading the operator typed file/tape path for
	the next volume in restore.

8.	Implemented a "-F script" option to restore which permits the
	user to specify a script which will be launched at the
	beginning of each tape, useful for automatic programming of
	tape changers for example. See the restore man page for the
	script parameters and return codes.

9.	Small fix for the QFA routines provided by Uwe Gohlke 
	<uwe@ugsoft.de>, and some recommendations for QFA uses in
	the man pages.

10.	Fixed the multivolume restoring where making a mistake
	to the 'Mount next tape' prompt caused several blocks to
	be lost.

11.	Enhanced the -e option of dump to take as a parameter a
	comma separated list of inode numbers.

12.	Added the -E option to dump which specify a file containing
	inode numbers to exclude from the dump.

13.	Fixed the compressed multi-volume dump + restore.

Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
==================================================================

1.	Made dump report the number of blocks dumped per volume.
	Thanks to Kenneth Porter <shiva@well.com> for the suggestion.

2.	Fix a bug in dump where waiting too much at the 'change volumes'
	question caused the volume to be rewritten. Thanks to
	Graham Reed <greed@users.sourceforge.net> for reporting the
	bug and providing a patch.

3.	Added a compression option to dump, contributed by Jerry
	Peters <gapeters@worldnet.att.net>.

	WARNING: the compression works only on files/pipes and 
	drives supporting variable block size.

	WARNING2: tapes created using the compression feature are
	incompatible with the standard dump tape format, and a
	version of restore >= 0.4b22 will be needed for extraction.

4.	Fixed some compilation problems for glibc 2.2.2 and 64 bit 
	architectures. Thanks to Paul Slootman <paul@debian.org> for
	the patch and to Bdale Garbee <bdale@gag.com> for forwarding
	it upstream.

5.	Many cleanups (CPP defines, const char warnings, check of
	ext2fs COMPAT flags, time_t cleanups, added libext2 version
	in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.

6.	Made --prefix option work in configure. All the install path
	are now based on the configure parameters.

7.	Added the Quick File Access mode in dump/restore, contributed
	by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
	a file tape position for each inode, and this file is used by 
	restore (if called with parameter Q and the filename)
	to directly position the tape at the file restore is currently 
	working on.  This saves hours when restoring single files from
	large backups, saves the tapes and the drive's head. Use
	--enable-qfa option of configure to compile in the QFA support.

8.	Added the possibility to dump several files and directories
	in a single invocation of dump. Thanks to Uwe Gohlke 
	<uwe@ugsoft.de> for implementing this option.

9.	Fixed the dumping and restoring of files with holes
	(files ending with holes didn't get dumped or restored 
	correctly).

10.	Fixed a socket descriptor leak in dump, which leaved opened
	3 file descriptors per dump process (and there is one dump
	process per tape).

11.	Fixed dump large file system support, by explicit use of
	open64/lseek64/etc functions (explicit use needed because 
	e2fsprogs libraries don't behave well when compiled with 
	FILE_OFFSET_BITS=64).

Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
======================================================================

1.	Fixed some bugs in the dump -w|-W logic introduced by
	the previous version. Thanks to Andreas Dilger 
	<adilger@turbolinux.com> for his help on this one.

2.	Fixed again a compilation problem when using old e2fs
	headers (filesystem label related). Thanks to many users
	who reported this stupid error.

3.	Fixed a build problem on old lib5 based systems dealing with 
	_PATH_MNTTAB being undefined. Thanks to John Adams
	<johna@onevista.com> for reporting the bug.

4.	Improved the error detection in restore when creating
	the temporary files in TMPDIR. Now restore will corectly
	report a 'no space left on device' error instead of 
	strange errors which could imply an archive corruption.
	Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
	bgjenero <bgjenero@sympatico.ca> for reporting the bug.

5.	Added the throughput information in dump's progression
	messages.  Thanks to Andreas Dilger <adilger@turbolinux.com> 
	for the patch.

6.	Use libext2fs's inode scanning routines, which are particularly
	robust when dealing with errors (especially when having some
	bad blocks on the filesystem). Many thanks to Colin
	<colin@horizon.com> for reporting the bug, investigating
	the issues, finding a workaround, writing the patch and
	fully testing it... (of course, if this patch will break
	anything, he is to blame for :-)).

7.	Made dump and restore LFS aware. Dump can dump a filesystem
	containing large files, generate a large file on output and
	restore can restore them. This feature is not enabled by
	default, use --enable-largefile option of configure to enable
	it (you need to have a LFS aware glibc though). Thanks to
	Andrea Arcangeli <andrea@suse.de> for submitting the patch,
	and to Theodore T'so <tytso@valinux.com> for his always
	useful thoughts.

8.	Made dump ask upon a tape write error if it should rewrite
	the current volume (assume this is a bad tape) or if it should
	assume an end-of-tape condition (useful for tape drives which
	behaves badly at the end of the tape). Thanks to Andreas
	Dilger <adilger@turbolinux.com> for the suggestion.

Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
=======================================================================

1.	Fixed a small compilation problem due to a change
	in the definintion of the struct sigaction in
	glibc 2.0 / libc5. Thanks to Gunther Schlegel 
	<schlegel@riege.de> for reporting the bug and to
	Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
	a fix.

2.	Modified the label and uuid analysis in order to be 
	self-contained (independant of kernel/libc headers). This 
        should fix the compile with older kernel/libc headers and
	will preserve the functionality. Thanks to Bernhard Erdmann
	<bernhard.erdmann@gmx.de> for reporting the bug.

3.	The 'exclude inode' option, if applied to a directory
	inode, excludes now correctly all the leaves of this 
	directory. Thanks to John R. Dennison 
	<gerdesas@users.sourceforge.net> for reporting the bug.

4.	Fixed the '-e' option to disable the possibility
	to exclude the root inode (which causes the dumps to
	be unreadable by restore). Prevented array overflow
	when multiple -e options are used.

5.	Fixed dump to correctly interpret a filesystem argument
	which is a mountpoint and it is not an absolute path 
	(as specified in the fstab). Thanks to Bernhard R. Erdmann 
	<be@berdmann.de> for reporting the bug.

6.	Made dump able to backup files larger than 2 GB. Note that
	dump still doesn't cope with files larger than 4 GB.

7.	Restore the real uid and gid before invoking an external
	RSH program (big hole when dump or restore is suid root!).

8.	Get the values for the default tape device and the location
	of fstab file from the system headers. Thanks to
	Andreas Dilger <adilger@turbolinux.com> for the patch.

9.	Made dump -w|-W report all recognized filesystems 
	present in either /etc/fstab or /etc/dumpdates, and present
	the list in the same order as in fstab file. Thanks
	to Andreas Dilger <adilger@turbolinux.com> for the patch.

10.	Made dump's -a (automatic end of tape detection) the
	default. Specifying one of -B, -c, -d or -s options will
	override the EOM detection. Thanks to Andreas Dilger
	<adilger@turbolinux.com> for the patch.

11.	Save the ext2 filesystem label into the dump volume label.
	Specifying a volume label on the command line (-L option)
	will override this feature. Thanks to Andreas Dilger
	<adilger@turbolinux.com> for the patch.

Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
=====================================================================

1.	Fixed the signal handling in dump (which I broke in 0.4b17)
	which was causing several strange dump failures (dump
	hanged or segmentation faults etc). 

2.	Specified the default blocksize in the dump man page.

3.	Changed two info messages of restore to be written on stdout
	instead of stderr in order to leave stderr only for errors
	or warnings. Thanks to Stephen Atwell 
	<satwell@urbana.css.mot.com> for the suggestion.

4.	Corrected an off by one calculation which prevented
	dumping a directory having a 1 character name length.
	Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
	for reporting the bug.

5.	Reinforce dump in order to allow only level 0 and no
	-u option when dumping a subdirectory, and document 
	this in the man page. Thanks to Bernhard Erdmann 
	<bernhard.erdmann@gmx.de> for reporting the bug.

6.	Fixed a small harmless bug in restore which caused
	in some conditions hard links to be restored several
	times (therefore generation some warning messages).
	Thanks to Kenneth Porter <shiva@well.com> for
	reporting the bug.

7.	Updated the RPM spec file to the latest RedHat version,
	providing FHS packaging and other cosmetic changes.
	You will need RPM version >= 3.0.5 in order to build the RPM.

8.	Updated the configure script to check for libtermcap
	before checking for libreadline, because we need this
	library in order to compile the readline support.

9.	Made dump understand the LABEL= and UUID= notation
	both in /etc/fstab and on the command line. Note that
	you will need the /proc filesystem in order to use
	these notations. Thanks to Erik Troan <ewt@redhat.com> 
	for providing the patch.

Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
===================================================================

1.	Fixed a potential buffer overflow in restore. Thanks
	to Stan Bubrouski <satan@fastdial.net> for reporting 
	the bug.

2.	Fixed a readline-related bug which prevented
	'cat DUMPFILE | restore -i -f -' from working. Thanks
	to Charles Karney <karney@users.sourceforge.net>
	for the bug report.

3.	Changed a few "panic" into "exit", causing restore to
	be more stable against some attacks (like the last one
	reported on Bugtraq, although the last version of restore
	was not vulnerable - just dumped core). Thanks to
	Andreas Hasenack <andreas@conectiva.com.br> for reporting
	the bugs to me.

4.	Removed the suid-root bit on dump and restore in the
	default build (and generated RPMs). It should be safer
	now. Users who need the suid-root capabilities in order
	to make network backups should read first the man page
	of dump and enable the suid bit manually.

5.	Added -ltermcap to the compile parameters for restore
	when using readline support, in order to make the compile
	process work on some systems (SuSE ?). Thanks to 
	Patrik Schindler <poc@pocnet.net> for reporting the bug.

Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
====================================================================

1.	The -F script is called now *only* at the end of a tape,
	not at the end of the dump. Thanks to Christian Haul
	<haul@informatik.tu-darmstadt.de> for the bug report.

	Normally, the device name and the current volume number
	are passed on the command line of the script. However,
	if you want the old style script (with no arguments
	passed on the command line), you can enable it in
	configure with the --enable-oldstylefscript.

2.	Use posix signal handling to preserve dump functionality 
	with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
	the patch.

3.	Made the exit code of restore in case of a 'C'ompare
	command reflect the result of the compare. An exit status
	of 0 means the dump archive is correct, 1 means tape errors,
	2 means that some files were modified. Thanks to Kenneth Porter
	<shiva@well.com> for the suggestion.

4.	Made (finally) quotes work in interactive restore.

5.	Small fixes in order to allow dump to compile with a 
	really old e2fsprogs version. Thanks to Ian Zimmerman 
	<itz@speakeasy.org> for the bug report.

6.	Add GNU readline capabilities to interactive restore.
	Use configure's --enable-readline flag to enable this feature.
	Thanks to Patrik Schindler <poc@pocnet.net> for the
	suggestion.

7.	Do the compare on the fly in restore 'C' mode (this will
	allow not to exhaust the available /tmp space when 
	ccmparing large files). Thanks to Kenneth Porter
	<shiva@well.com> for the suggestion.

Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
====================================================================

1.	Fixed some several duplicate 'DUMP: DUMP:' in the
	output of dump.

2.	Corrected the estimation of blocks to dump. Note that
	this is still wrong for large directory inodes, due
	to the size of a BSD directory entry on the tape
	(estimation is based on the size of the ext2 directory,
	which is smaller because it doesn't contain the null
	character at the end).

3.	Made dump report the total number of MB written to
	tape at the end of run. Thanks to W. Reilly Cooley
	<wcooley@nakedape.cc> for the patch.

4.	Added the -X option to restore giving the possibility
	to read the names of the files to be extracted/listed 
	from a text file (in addition of the command line). 
	Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the 
	patch.

5.	Added the device name and the current volume number
	as arguments to the end of tape script (dump -F option).

6.	Made the multi-volume dump work again (after having 
	broken it in 0.4b15). 

Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
===================================================================

1.	Added a prompt command in interactive restore mode. Thanks
	to Andreas Dilger <adilger@home.com> for the patch.

2.	Fixed a buffer overflow problem in dump (caused by 
	not checking the size of the filesystem parameter). 
	Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
	reporting this on Bugtraq (and to several dump users
	who forwarded me his mail).

3.	Added the '-F script' option to dump in order to 
	launch a script at the end of each tape (to be used
	with a tape changer, or to notify the sysadmin by
	pager etc.).

4.	Fixed a bug in restore compare code caused by the changes 
	I made in 0.4b14.

5.	Fixed the treatment of options using the old BSD syntax
	in both dump and restore.

Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
=======================================================================

1.	Fixed a bug in dump which may have caused invalid deleted 
	directories to be dumped out if they were deleted after the
	mapping pass. This could occure on active filesystem and lead
	to heap corruption (causing dump malfunction in many possible ways).
	Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
	bug and submitting the patch.

2.	Fixed the handling of the filesystem parameter in dump. A
	'/mnt/disk' parameter caused the disk contents to be dumped,
	but a '/mnt/disk/' parameter caused the mountpoint directory
	to be dumped (generally an empty directory).

3.	Improved the output of dump in order to tell which directory
	it is currently dumping (when dumping a subtree).

4.	Added the '-e' exclude inode option to dump. Thanks to
	Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.

5.	Added a REPORTING-BUGS file in order to provide a guide
	on how to correctly report a bug in dump/restore.

6.	Fixed a restore problem when restoring a hard link to an inode
	having the immutable or append-only attribute set. Thanks to
	Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.

7.	Fixed a compatibility problem between dumps made on little
	endian machines (the format was correct) and big endian 
	machines (the format was incorrect). This fix break the
	compatibility with the older dumps made on big endian 
	machines (sparc, m86k, ppc etc). For the first time in
	linux dump's history (I believe), the dumps made by *BSD, 
	Linux/alpha, Linux/sparc and Linux/x86 are compatible, 
	so interchangeable. Thanks to Rob Cermak
	<cermak@ahab.rutgers.edu> for submitting the bug and
	helping me test the fix.

8.	Fixed the way dump reports the remaining percent/time, if
	the number of blocks actually dumped exceeds the estimated
	number of blocks. Thanks to Jean-Paul van der Jagt 
	<jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.

Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
======================================================================

1.	Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
	<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.

2.	Removed the requirement to build the RPM as root from the
	spec file. Thanks to Christian Weisgerber 
	<naddy@mips.rhein-neckar.de> for submitting this.

3.	Fixed a bug in dump related to the 'filetype' feature of ext2fs,
	causing dump to block when dumping really huge filesystems.
	Many thanks to Patrik Schindler <poc@pocnet.net> for 
	helping me find this bug.

4.	Fixed the treatment for an interrupt signal when dump access
	the remote tape through RSH. Thanks to Christian Weisgerber
	<naddy@mips.rhein-neckar.de> for providing the patch.

5.	Fixed a bug which was causing dump/restore to display
	garbage characters instead of the remote host name.

Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
=====================================================================

1.	Small fix in the dump man page. Thanks to Thorsten Kukuk 
	<kukuk@suse.de> for submitting the patch.

2.	Fix for the exit code when using the size estimate option of
	dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
	submitting the patch.

3.	Handle EINTR in atomical reads/writes in dump, which was causing
	dump to fail on some systems. Thanks to Eric Jergensen
	<eric@dvns.com> for reporting the bug and submitting the patch.

4.	Handle more than 16 characters for the device names in dumpdates.
	(up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
	tracking down the problem and proposing the solution.

5.	Fixed a bug in dump which prevented the creation of the
	dumpdates file when doing a 0-level dump without already
	having a dumpdates file. Thanks to Patrik Schindler 
	<poc@pocnet.net> for reporting the bug.

6.	Changed the way dump 'S' flag reports the size estimate
	from number of blocks into bytes (making it compatible
	with the Solaris version, and simplifying things for
	amanda users). Thanks to Jason L Tibbitts III 
	<tibbs@math.uh.edu> for reporting the bug.

7.	Fixed a compatibility problem in linux/alpha dump tape format.
	Now the linux/alpha dump are (again) compatible with the
	other dump formats. But this breaks compatibility with
	older dumps made on alpha. Thanks to Mike Tibor 
	<tibor@lib.uaa.alaska.edu> for helping me in finding this bug.  

Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
======================================================================

1.	Added a '--enable-kerberos' to configure.

2.	Added a 'S' option to dump which determines the amount of space
	that is needed to perform the dump without actually doing it, similar
	to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
	<cermak@ahab.rutgers.edu>.

3.	Added a 'M' multi-volume option to dump and restore which enables
	dumping to multiple files (useful when dumping to an ext2
	partition to make several dump files in order to bypass the 2GB
	file size limitation). The 'f' argument is treated as a prefix and
	the output files will be named <prefix>001, <prefix>002 etc. With
	the 'M' flag, restore automatically selects the right file without
	asking to enter a new tape each time.

4.	Fixed a memory leak which was causing dump to grow very big
	(270MB when dumping a 10GB filesystem...). Thanks to Jason 
	Fearon <jasonf@netrider.org.au> for reporting the bug.

Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
======================================================================

1.	Make configure test if the system glob routines support 
	extended syntax (ALTDIRFUNC). If not, use the internal glob
	routines instead of system ones. Thanks to Bernhard Sadlowski 
	<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
	and helping me resolve this and other minor libc5 compiling
	glitches.

2.	Fix a problem when dumping a ext2fs with the 'filetype'
	feature enabled. Thanks to Patrick J. LoPresti 
	<patl@cag.lcs.mit.edu> for reporting the bug and to
	Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.

3.	Made the nodump flag work on directories. A directory which
	has the nodump flag gets never dumped, regardless of its
	contents.

4.	Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
	which allows dump on an active ext3 filesystem. However, this
	is a "quick and dirty" patch which enables backup of an ext3
	filesystem through the ext2 compatibility (by ignoring the
	NEEDS_RECOVERY bit). The journal file is not recognized and
	it is dumped (it should not). 

5.	Test the superblock compatibility flags when dumping, in order
	to be sure that we know how to deal with specific features.

Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
====================================================================

1.	Use lchown instead of chown, fixing a possible security problem 
	when restoring symlinks (a malicious user could use this
	to deliberately corrupt the ownership of important system files).
	Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
	this and providing the patch.

Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
====================================================================

1.	Put dump sources under CVS, added Id tags in all files so
	one can use 'ident' on binary files.

2.	Added the dump/restore version in the usage text so one can
	easily verify the version he is using.

3.	Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
	a va_start/va_end problem on linux-ppc (always call va_start
	va_end in pairs each time we use a vararg function).

4.	Added again the DT_* constants because old libc does not
	contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
	for submitting the bug report.

5.	Use ext2fs_llseek instead of llseek. With recent e2fsprogs
	this should enable dumping big (huge) filesystems.

6.	Added the RSH environment variable in order to be able to
	use a rsh replacement like ssh when doing remote backups (and
	bypass the security limitations of rcmd). Now you can do remote
	backups without being root (or making dump setuid root).

7.	Modified again the way dumpdates works. For incremental dumps,
	we need to read dumpdates even if we are not using 'u' option.
	Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
	this should work.

Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
===================================================================

1.	Removed the 'k' flag from the restore 'about' text if kerberos
	was not compiled in.

2.	Prototyped (f)setflags from e2fsprogs and corrected the calls
	to them (fsetflags takes a char*, setflags an open fd!).

3.	(f)setflags is called only if the flags aren't empty. If the
	file is a special file, a warning is printed, because changing
	flags implies opening the device. Normally, a special file
	should not have any flag... (Debian bug #29775, patch provided
	by Abhijit Dasgupta <abhijit@ans.net>).

4.	Made possible to dump a file system not mentioned in /etc/fstab.
	(Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).

5.	Changed the default behaviour to not create dumpdates
	unless 'u' option is specified. Removed the old "debian-patch"
	which provided the same thing. (Debian bug #38136, #33818).

6.	Removed all those dump*announce, since they were getting old...

7.	Added warning messages if dumpdates does not exist and
	when an inferior level dump does not exist (except for a level 0
	dump).

8.	Debugged the glob calls in interactive mode: restore used a 
	dirent struct which was different from the /usr/include/dirent.h
	one (this used to work, is it a glibc2 change?), so none of the 
	compat glob (which used /usr/include/dirent.h) or the system glob 
	worked. Restore use now the system dirent (and the system 
	DT_* constants), which are compatible with BSD ones.

9.	Added a configure flag (--with-dumpdatespath) to specify
	the location of dumpdates file. By default, it is 
	/etc/dumpdates.

10.	Added the "AUTHOR" and "AVAILABILITY" sections and 
	included the current date/version in man pages.

11.	Corrected the estimation of remaining time when
	the operator doesn't change the tapes quickly enough. This
	was an old bug, I thought I corrected it, and discovered
	that in fact it was corrected in two different places, so
	the results canceled each other...

Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
===================================================================

1.	Integrated multiple patches from RedHat, Debian and SuSE:

	- tweak dump/itime.c to not try to read dumpdates if the 'u' option 
	  isn't specified.
	- several fixes in the man pages.
	- update the default tape device to /dev/st0.
	- many updates for Linux Alpha (byte ordering, size_t etc).
	- buffer overruns.
	- use environment variable for TMPDIR (instead of /tmp).
	- use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
	- workaround egcs bug (RedHat bugs #4281 and #2989).
	- wire $(OPT) throughout Makefile's.

2.	Upgrade the dump revision to 1, making possible to dump filesystems
	made with e2fsprogs-1.15 or newer. Nothing seems to break...

3.	Fix some compile warnings, prototype all functions.

4.	Use glibc err/glob instead of internal compatibility
	routines (only if available).

5.	Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
	by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).

Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
======================================================================

1.	Integrated the changes from FreeBSD-3.1-RELEASE
	(mostly bug fixes, buffer overruns, dump has now an "automatic
	tape length calculation" flag, dump/restore can use kerberos now
	(this is NOT tested), use environment variables for TAPE and
	RMT etc.).

2.	Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)

3.	Corrected a bug in restore when using 'C' option with multi-volumes
	tapes (files splited accros two tapes give "size changed" errors
	when comparing).

4.	Corrected the long standing bug when dumping multiple tapes.
	This works for me, needs further testing.

Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
====================================================================

1.	Dump now runs correctly on kernels 2.1.x
	Fix made by Gerald Peters <gapeters@worldnet.att.net>

Changes between versions 0.4b2 and 0.4b3
========================================

1.	Use realpath() if available

2.	Report statistics

Changes between versions 0.4b1 and 0.4b2
========================================

1.	Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
	the patch)

2.	Fixed restore to make it able to read FreeBSD 2.x dumps again

3.	Fixed configure.in to correctly handle --enable-rmt

Changes between versions 0.3 and 0.4b1
======================================

1.	Integrated the changes from 4.4BSD-Lite2

2.	Integrated the patches from Debian and Red Hat

3.	Portability changes: use the __u32, __u16, __s32, and __s16 types

4.	Changed dump to use the Ext2fs library to get block addresses.  This
	should solve the endianness problem on SparcLinux.

5.	Created a configure.in file (shamelessly stolen from the e2fsprogs
	distribution's one) to use autoconf

6.	Fixed a few minor bugs

Changes between versions 0.2e and 0.2f
======================================

1.	Added the creation of named pipes (fifos) in restore.

2.	Added the -N flag in the restore manual page.

3.	Added the file kernel.patch which contains the llseek() optimization
	patch for 1.2.x kernels.

4.	Fixed a bug in the restoration of symbolic links: owner and group were
	not restored.

5.	Integrated some changes from FreeBSD 2.2.

6.	Added a call to ftruncate() after restoring each file to restore
	correctly files ending by a hole.

Changes between versions 0.2d and 0.2e
======================================

1.	Fixed a bug in the "set owner/mode" process.  Every file was restored
	with owner = root (0) and group = root/wheel/whatever (0).

Changes between versions 0.2c and 0.2d
======================================

1.	Dump is now able to backup 2GB+ filesystems.

2.	Dump and restore can now be linked as static binaries.

Changes between versions 0.2b and 0.2c
======================================

1.	Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.

Changes between versions 0.2a and 0.2b
======================================

1.	Really fixed the bug that I should have corrected in 0.2a.

2.	Enabled optimization again.

Changes between versions 0.2 and 0.2a
=====================================

1.	Disabled the optimization during compilation.

Changes between versions 0.1 and 0.2
====================================

1.	Fixed a bug in fstab.c which caused a null pointer to be stored in
	the fs_type field (actually, I modified the file fstab.c to make it
	use the mntent functions).

2.	Dump and restore now use a 4.3 BSD compatible dump format.  Backups
	made by dump should be readable by the BSD restore and backups made
	by the BSD dump should be readable by restore.  Unfortunately, this
	means that the dump format has changed between version 0.1 and version
	0.2 :-(

3.	Dump is now able to backup a subtree, it is no longer limited to whole
	filesystems like the BSD version.

4.	Dump now uses ext2_llseek() so it is able to backup filesystems bigger
	than 2 GB.

Changes between versions 0.0 and 0.1
====================================

1.	Now create links rdump and rrestore during the `make install' step.

2.	Linux port specific bugs added to the manual pages

3.	Incorrect estimation of the number of tapes blocks fixed when doing
	incremental backups.

4.	Better ls-like format in restore in interactive mode.
