 1.44  14-Mar-2022  mlelstv Silently ignore fstab entries with NAME= entries that cannot be resolved.
Fixes PR 56249.
 1.43  01-Mar-2019  christos branches: 1.43.2;
Use getfsspecname() to fill the filesystem argument in dumpdates.
While here, make sure that the error strings terminate with newline
consistently, and add a function that adds the system error string.
 1.42  08-Sep-2013  mlelstv branches: 1.42.18; 1.42.26;
Fix handling of NAME aliases in /etc/fstab.
 1.41  15-Jun-2013  christos handle new lfs split
 1.40  13-Jan-2013  dholland Use more static.
 1.39  13-Jan-2013  dholland Add some const.
 1.38  07-Apr-2012  christos branches: 1.38.2;
factor out rawname() from dump, fsck, savecore.
 1.37  07-Apr-2012  christos use getfsspecname()
 1.36  18-Dec-2006  christos branches: 1.36.36;
Convert a couple of "(void)&" constructs to volatile.
Flag various unused parameters in restore and dump so that these will
compile with -Wextra. (Note: restore uses some stuff from dump.)
 1.35  24-Jun-2006  perseant Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.

dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.
 1.34  27-Jun-2005  christos sprinkle const
 1.33  21-Apr-2004  christos Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.
 1.32  15-Mar-2004  lukem Adjust tstart_volume (volume start time) by the time spent in query(),
similar to the adjustment for tstart_writing made in optr.c rev 1.4.
Should fix PR bin/19711 from matthew green.
 1.31  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.
 1.30  02-Apr-2003  fvdl Add support for UFS2. UFS2 is an enhanced FFS, adding support for
64 bit block pointers, extended attribute storage, and a few
other things.

This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

Originally written by Kirk McKusick and Network Associates Laboratories for
FreeBSD.
 1.29  27-Mar-2003  lukem Use "wall -g operator" (instead of private code) to broadcast() messages to
members of the operator group.
Don't install "setgid tty", and remove now unnecessary gid/egid swapping.
Remove utmp trawling code pulled in from usr.bin/who.
The Code is now simpler, and more portable (without the utmp cruft) too.

This is derived from similar work in OpenBSD.
 1.28  18-Aug-2002  yamt save/restore errno in signal handlers.
 1.27  16-Aug-2002  itojun defend against malicious line in ut_line, which could cause unwanted
writes to anything under /dev. revoke setuid/gid privs earlier.
From: xs@kittenz.org
 1.26  02-Aug-2002  christos support utmpx
 1.25  25-Dec-2001  lukem Fixes from FreeBSD:
- Fix error if first tape was write protected. Fix NetBSD PRs 4754 and 6098.
- Make dump exit codes confirm to manual page.
- Use \a instead of \7 to make noise.
- Fix estimated number of tapes for huge dumps to cartridges.
- Use <sys/queue.h> SLIST_* instead of home-rolled lists.
- Do not exit if unable to read or create /etc/dumpdates.
- Support output (tape) device returning ENOSPC for end-of-media on a write.

Fixes by me:
- Remove unused ddates_in.
- Don't dump core if SIGINFO is received before 1 second has elapsed.
- Only process SIGINFO in current "active" child.
- Don't dump core in -w if dumpdates wasn't readable and ddatev == NULL
- Minor KNF; wrap some lines
 1.24  24-Dec-2001  lukem For dump_lfs(8), in getfstab(), only "lfs" (instead of "ufs" or "ffs").
Fix from Minoura Makoto in [bin/10525].
 1.23  23-Dec-2001  lukem nuke trailing whitespace
 1.22  22-Dec-2001  lukem - use correct type for minTime in findlru() (size_t instead of int)
- clean up whitespace
 1.21  01-Nov-2001  lukem fix -Wshadow warnings
 1.20  25-Oct-2001  lukem in msg(), don't call va_list using functions twice in a row without calling
va_start() in between; reorder code so that we call vsnprintf and then
just fputs that buffer. crank the size of lastmsg whilst we're here
problem noted by Hideo Saito in [bin/14348].
 1.19  15-Oct-2001  blymn Add the capability for dump to print timestamps on all informational
messages.
 1.18  08-Aug-2001  david Patch to drop setgid tty privs until forking for operator notification
 1.17  28-May-2001  lukem * improve parsing of file-systems-to-dump when a path is given:
- if it's a path to an unmounted file-system listed in /etc/fstab, use
that instead of assuming the user wanted a subtree dump of the parent
directory. this restores the behaviour of dump before the subtree
dumping code went in.
- if it's a path to a mounted file-system which is not in /etc/fstab,
use the info from getmntinfo(3). previously, dump would choke.
* implement error checked malloc(), calloc(), strdup(), and use
appropriately (some of the calloc()s weren't being checked)
* use 'file-system' instead of 'filesystem' in the man page
 1.16  28-May-2001  lukem unifdef !__STDC__ (missed in previous)
 1.15  27-May-2001  lukem knf to ansi
 1.14  10-Oct-2000  is Format string cleanups by Bill Sommerfeld.
 1.13  01-Apr-1998  kleink branches: 1.13.2; 1.13.10;
Need <time.h> for time(), localtime() and ctime() prototypes.
 1.12  15-Sep-1997  lukem * cleanup for WARNS=1
* fix use of .Nm
* comment out some unused(?) functions
 1.11  27-May-1997  mrg fix off by one bug.
 1.10  21-Apr-1997  thorpej Don't need to account for space for NUL, as it's included in the
sizeof(_PATH_DEV), noted by Chris Demetriou <cgd@netbsd.org>
 1.9  21-Apr-1997  thorpej Add missing `-', noted by Erik Fair <fair@cesium.clock.org> on
current-users.
 1.8  21-Apr-1997  mrg be safe with buffers.
 1.7  15-Apr-1997  lukem remove use of "register".
 1.6  10-Apr-1997  lukem Implement changes from [bin/1915]
* 'w' and 'W' display the year
* verbosity additions displaying total & per-volume transfer times and rates
 1.5  16-Jan-1997  perry fix pr 2977 -- only try to dump ufs/ffs partitions

Document what rdump is (was once) for. PR 53442.

Use getfsspecname() to fill the filesystem argument in dumpdates.
While here, make sure that the error strings terminate with newline
consistently, and add a function that adds the system error string.

Add -U flag to dump(8) and dump_lfs(8) to specify dumpdates entry
This address situations where dump(8) cannot figure out the device being
dumped. It also allows tracking of subvolume dumps by using virtual
device as dumpdates entry.

Bump date for previous.
