not blocked by raising the pil, a reciever may be interrupted while holding
a spinlock. If the sender does not defer interrupts throughout the entire
operation it may be interrupted and try to acquire a spinlock held by a
reciever, leading to a deadlock due to the synchronization used by the
ipi handlers themselves.

as a macro w/o messing things up. This is really an abuse and we will back
this out as soon as the abusers have been fixed. Add a comment to this
effect.
With this change, the XFree86-4 port now builds.

Giant for the time being. This should allow kern.giant.proc to be set
to 0 for the time being.
Move the network code from using cr_cansee() to check whether a
socket is visible to a requesting credential to using a new
function, cr_canseesocket(), which accepts a subject credential
and object socket. Implement cr_canseesocket() so that it does a
prison check, a uid check, and add a comment where shortly a MAC
hook will go. This will allow MAC policies to seperately
instrument the visibility of sockets from the visibility of
processes.

Back out ip_output.c,v 1.143 and ip_mroute.c,v 1.69 that allowed
ip_output() to be called with a NULL route pointer. The previous
paragraph shows why this was a bad idea in the first place.

to test req->td for NULL values and then do somewhat more bizarre things
relating to securelevel special-casing and suser checks. Remove the
testing and conditional security checks based on req->td!=NULL, and insert
a KASSERT that td != NULL. Callers to sysctl must always specify the
thread (be it kernel or otherwise) requesting the operation, or a
number of current sysctls will fail due to assumptions that the thread
exists.

NULL, turn warning printf's into panic's, since this call has been
restructured such that a NULL cred would result in a page fault anyway.
There appears to be one case where NULL is explicitly passed in in the
sysctl code, and this is believed to be in error, so will be modified.
Securelevels now always require a credential context so that per-jail
securelevels are properly implemented.

3c996B-T, with the 5701 rev B5 ASIC). One thing that confuses me
still is that the 'link state change' bit in the status block seems
to change state an awful lot. I have a workaround for this in place
now, but it needs more investigation. For the moment though, this
is enough to get the driver to work with this card.

this should be backed out until further investigation proves otherwise,
or a proper fix can be provided.
This increases the number of concurrent outgoing connections from ~4000
to ~16000. Other OSes (Solaris, OS X, NetBSD) and many other NAT
products have already made this change without ill effects, so we
should not run into any problems.

method-based inter-process security checks. To do this, introduce
a new cr_seeotheruids(u1, u2) function, which encapsulates the
"see_other_uids" logic. Call out to this policy following the
jail security check for all of {debug,sched,see,signal} inter-process
checks. This more consistently enforces the check, and makes the
check easy to modify. Eventually, it may be that this check should
become a MAC policy, loaded via a module.

soon because it's just getting harder and harder to find switches
that correctly implement the GET ALL NEXT subcommands for the SNS
protocol.
Latch up result out pointer and set a busy flag when we're looking
at the response queue. This allows for a cleaner way to make sure
we don't get multiple CPUs trying to read the same response queue
entries.
Change how isp_handle_other_response returns values (clarity).
Make PORT UNAVAILABLE the same as PORT LOGOUT (force a LIP).
Do some formatting changes.
