e7e5b53bf1 Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

a2cd889979 The current /etc/dumpdates file restricts device names to 32 characters.
With the addition of various GEOM layers some device names now exceed
this length, for example /dev/mirror/encrypted.elig.journal. This
change expands the field to 53 bytes which brings the /etc/dumpdates
lines to 80 characters. Exceeding 80 characters makes the /etc/dumpdates
file much less human readable. A test is added to dump so that it
verifies that the device name will fit in the 53 character field
failing the dump if it is too long.

This change has been checked to verify that its /etc/dumpdates file
is compatible with older versions of dump.

242bd272d9 The dump, fsck_ffs, fsdb, fsirand, newfs, makefs, and quot utilities
include sys/time.h instead of time.h. This include is incorrect as
per the manpages for the APIs and the POSIX definitions. This commit
replaces sys/time.h where necessary with time.h.

The commit also includes some minor style(9) header fixup in newfs.

This commit is part of a larger effort by Garrett Cooper started in
//depot/user/gcooper/posix-conformance-work/ -- to make FreeBSD more
POSIX compliant.

af9e967365 When using dump to generate level 0 dumps which are then rsync'ed
to a remote machine, the fact that the dump date is stored with
each header (inode) record makes rsync significantly less efficient
than necessary. This also applies to inode access times when they
are not important data to retain. When implementing an offsite
backup solution of this type, these dates in particular are not
important, especially if it prevents effective offsite backups.

325fee4370 Fix an error in dumping large sparse files containing extended attributes. 2007-02-27 07:28:17 +00:00
mckusick
01ee9020b3 Update the dump program to save extended attributes. Update
the restore program to restore all dumped extended attributes.

If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.

The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.

This resolves PR 93085 which will be closed once the code
has been MFC'ed.

Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

completed, and the dump process exits). Previous wording was confusing

of the bitmap to find that inode's state. Instead skip that directory
entry and print a warning.

afa1411453 Convert the live dump command (`dump -L') to use mksnap_ffs instead
of trying to directly create the snapshot itself. This change allows
users logged into the system as operator to run live dumps.

Note that dump no longer tries to create the snapshot in the root of
the filesystem, but rather in a .snap directory in the root of the
filesystem. The reason is that the operator is usually not permitted
to write into the root of the filesystem. The newfs command and
background fsck have both been modified to create a .snap directory
in the root of the filesystem, but if neither of these have been run,
then the .snap directory must be created manually by the superuser
before a live dump can be run. The .snap directory should be owned
by user root and group operator and set to mode 770.
