hannken 1f51c28099 Snapshot support for dump(8):
- New option `-x backup' takes the dump from a snapshot backed up by `backup'.
  The snapshot will be deleted on exit.

- New option `-X' as a synonym for `-x mountpoint' where `mountpoint' is the
  file system to be dumped.

lukem c9e78fddc5 Signal handlers should manipulate 'volatile sig_atomic_t' instead of 'int'. 2004-08-08 09:46:16 +00:00
hannken 8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Welcome to 2.0F.

tls 539a3fbb0a The sysctl returning the amount of memory in the system returns "int",
which is silly.  Luckily, it really does return the correct result if
interpreted as an unsigned int.  This change lets dump work on 32-bit
systems that have more than 2GB of RAM.

fvdl 42614ed3f3 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.

lukem ec029d0aa9 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.

lukem 19eb88dfa1 Add fix from FreeBSD traverse.c 1.16:
Files in subdirectories of directories that have the nodump flag set
	are sometimes incorrectly being dumped.

	The problem arises because the subdirectory only gets its entry
	cleared from usedinomap if it is also present in dumpinomap, and it is
	the absence of a directory in usedinomap that internally indicates
	that the directory is under the effects of UF_NODUMP (either directly
	or inherited).
