explicit access control checks to delete and list extended attributes
on a vnode, rather than implicitly combining with the setextattr and
getextattr checks. This reflects EA API changes in the kernel made
recently, including the move to explicit VOP's for both of these
operations.

UMA_ZFLAG_INTERNAL zones at all. Apparently, Wilko's alpha
was crashing while entering multi-user because, I think, we
were calculating the garbage cachefree for pcpu caches that
essentially don't exist for at least the 'zones' zone and it so
happened that we were reading from an unmapped location.

critical region, we wrap some syscalls for thread cancellation point, and
when syscalls returns, we call _thr_leave_cancellation_point, at the time
if a signal comes in, it would be buffered, and when the thread leaves
_thr_leave_cancellation_point, buffered signals will be processed, to avoid
messing up normal syscall errno, we should save and restore errno around
signal handling code.

devfs(8) rules in rc(8). It is most useful for applying
rules to devfs(5) mount points in /dev or inside jails.
The following line of script is sufficient to
mount a relatively useful+secure devfs(5) in a jail:
devfs_mount_jail /some/jail/dev
Some new shell routines available to scripts that source
rc.subr(5):
o devfs_link - Makes it a little easier to create symlinks
o devfs_init_rulesets - Create devfs(8) rulesets from devfs.rules
o devfs_set_ruleset - Set a ruleset to a devfs(5) mount
o devfs_apply_ruleset - Apply a ruleset to a devfs(5) mount
o devfs_domount - Mount devfs(5) and apply some ruleset
o devfs_mount_jail - Mount devfs(5) and apply a ruleset
appropriate to jails.
Additional rulesets can be specified in /etc/devfs.rules.
If the devfs_system_ruleset variable is defined in rc.conf
and it contains the name of a ruleset defined in /etc/defaults/devfs.rules
or user supplied rulesets in /etc/devfs.rules then that ruleset will
be applied to /dev at startup by the /etc/rc.d/devfs script. It can
also be applied post-startup:
/etc/rc.d/devfs start
This is a more flexible mechanism than the previous method of using
/etc/devfs.conf. However, that method is still available.
Note: since devfs(8) doesn't provide any way for creating symlinks
as part of a ruleset, anyone wishing to create symlinks in a devfs(5)
as part of the bootup sequence will still have to rely on /etc/devfs.conf.

ntp_update_second twice when we have a large step in case that step
goes across a scheduled leap second. The only way this could happen
would be if we didn't call tc_windup over the end of day on the day of
a leap second, which would only happen if timeouts were delayed for
seconds. While it is an edge case, it is an important one to get
right for my employer.

ultimate trigger for the follow-up fixes in revisions 1.78, 1.80,
1.81 and 1.82 of trap.c. I was simply too pre-occupied with the
gateway page and how it blurs kernel space with user space and
vice versa that I couldn't see that it was all a load of bollocks.
It's not the IP address that matters, it's the privilege level that
counts. We never run in user space with lifted permissions and we
sure can not run in kernel space without it. Sure, the gateway page
is the exception, but not if you look at the privilege level. It's
user space if you run with user permissions and kernel space otherwise.
So, we're back to looking at the privilege level like it should be.
There's no other way.

- Fix up TX speed changes.
- Make mpi-350 cards sort-of work with new firmware. It RXs okay but TXs
only work for about 14 packets then fails to get an interrupt. The
TX watchdog fires. It has been reported that my hack for now doesn't
break cards with the older firmware. It appears my card has lost
the ability to RX or TX at all but other peoples cards work. I assume
it got damaged in tansport.

gethostname()'s old and new signatures without requiring a library
bump. Note that programs which called gethostname() with a negative
argument were already broken, since the same type conversion was done
by the old implementation. Add a note in the Makefile so that whoever
next bumps the libc revision will delete the kluge at the same time
(as it will no longer be necessary). This is only operative on 64-bit
platforms.

count handling of station entries in hostap mode:
Input path:
o driver is now expected to find the node associated with the
sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
use within the wlan module and is responsible for cleaning up
on return
o the antenna state is no longer passed up with each frame; this
is now considered driver-private state and drivers are responsible
for keeping it in the driver-private part of a node
Output path:
Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode). On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver. This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node. This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock. As a byproduct we also reduce the overhead
for sending management frames (minimal). Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame. Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler). This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.
Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
pointers may never be null)
