8ca3089abc When sending packets directly to the DHCP server, use a socket and send

aed3576d26 restore(8) does not check for write failure while building two temp
files containing directory and ownership data. If /tmp fills, the
console is blasted with zillions of "file system full" errors, and
restore continues on, even though directory and/or ownership data
has been lost. This is particularly likely to happen when running
from the live CD, which has little /tmp space.

14320f1e7f Add a new flag, '-C' which enables a special mode that is intended for
catastrophic recovery.  Currently, this mode only validates whether a
cylindergroup has good signature data, and prompts the user to decide
whether to clear it as a whole.

This mode is useful when there is data damage on a disk and you are
working on copy of the original disk, as fsck_ffs(8) tends to abnormally
exit in such case, as a last resort to recover data from the disk.

6764f54349 In route.c in newroute() there's a call to exit(0) if the command was
'get'. Since rtmsg() always gets called and returns 0 on success and -1
on failure, it's possible to exit with a suitable exit code by calling
exit(ret != 0) instead, as is done at the end of newroute().

72d945abcc Add a "spindown" facility to ata-disks: If no requests have been received
for a configurable number of seconds, spin the disk down.  Spin it back
up on the next request.

Notice that the timeout is only armed by a request, so to spin down a
disk you may have to do:

	atacontrol spindown ad10 5
	dd if=/dev/ad10 of=/dev/null count=1

To disable spindown, set timeout to zero:

	atacontrol spindown ad10 0

In order to debug any trouble caused, this code is somewhat noisy on the
console.

Enabling spindown on a disk containing / or /var/log/messages is not
going to do anything sensible.

Spinning a disk up and down all the time will wear it out, use sensibly.

d8f7b008a7 For a mounted file system which is read-only, when
doing the MNT_RELOAD, pass in "ro" and "update"
string mount options to nmount() instead of MNT_RDONLY and MNT_UPDATE flags.

Due to the complexity of the mount parsing code especially
with respect to the root file system, passing in MNT_RDONLY and MNT_UPDATE
flags would do weird things and would cause fsck to convert the root
file system from a read-only mount to read-write.

To test:
 - boot into single user mode
 - show mounted file systems with: mount
 - root file system should be mounted read-only
 - fsck /
 - show mounted file systems with: mount
 - root file system should still be mounted read-only

2b2c3b23d1 Dummynet has a limit of 100 slots queue size (or 1MB, if you give
the limit in bytes) hard coded into both the kernel and userland.
Make both these limits a sysctl, so it is easy to change the limit.
If the userland part of ipfw finds that the sysctls don't exist,
it will just fall back to the traditional limits.

(100 packets is quite a small limit these days. If you want to test
TCP at 100Mbps, 100 packets can only accommodate a DBP of 12ms.)

Note these sysctls in the man page and warn against increasing them
without thinking first.

33663c7246 In pass2check(): Be more strict with the inode information before further

8f0931174a Be more careful when checking superblock. We have already checked
whether fs_bsize is larger than MINBSIZE, which is larger than the
value that is used to compared with fs_bsize, the sizeof fs, so the
check followed, will be always true.

By inspecting the code and some old commit log, I believe that the
check must be that *fs_sbsize* is larger than sizeof fs.  We round
up the size to nearest dev_bsize, as the smallest accepted fs_sbsize,
personally, I think this can be even changed to equal, because this
number is mostly an invariant in file systems.

With this check, fsck_ffs(8) will be more picky and has better
chance rejecting bad first superblock rather than referring to bad
value it supplied, thus gives better chance for it to check the
filesystem carefully.
