vn_start_write() on the given vnode will be successful. VOP_LEASE() may
help to solve this problem, but its return value ignored nearly everywhere.
For now just assume that the missing upper layer on write means insufficient
access rights (which is correct for most cases).
there is no need to wake all waiters to assure that the highest priority
thread is run. As the semaphore code is written, there was no correctness
problem, but the change improves sem_post() performance.

wakeup proc0 by hand to enforce the timeout.
- When swapping out a process, keep the process locked via the proc lock
from the first checks up until we clear PS_INMEM and set PS_SWAPPING in
swapout(). The swapout() function now must be called with the proc lock
held and releases it before returning.
- Comment out the code to attempt to lock a process' VM structures before
swapping out. It is broken in that it releases the lock after obtaining
it. If it does grab the lock, it needs to hand it off to swapout()
instead of releasing it. This can be revisisted when the VM is locked
as this is a valid test to perform. It also causes a lock order reversal
for the time being, which is the immediate cause for temporarily
disabling it.
the process in question locked as soon as we find it and determine it to
be eligible until we actually kill it. To avoid deadlock, we don't block
on the process lock but skip any process that is already locked during our
search.

a problem. Add a comment explaining why it is safe to skip lock order
checking with try locks.
- Remove the ithread list lock spin lock from the order list.
sleep locks.
- Delay returning from ithread_remove_handler() until we are certain that
the interrupt handler being removed has in fact been removed from the
ithread.
- XXX: There is still a problem in that nothing protects the kernel from
adding a new handler while the ithread is running, though with our
current architectures this is not a problem.

toggled after boot.

Pro and Raylink cards with version 5 firmware. Only infra-structure
mode has been tested. Specific changes for this feature are:
o Add RFC1042 encapsulation of IP datagrams
o Add authentication and association
o Decode of the beacon (although not used)
Other changes have been made:
o Pass command completion status to *_done (in place for
adding proper error recovery)
o Move a couple of state variables into the current
network parameters structure. This is in prep. for
dealing with roaming.

follows: the effective uid of p1 (subject) must equal the real, saved,
and effective uids of p2 (object), p2 must not have undergone a
credential downgrade. A subject with appropriate privilege may override
these protections.
In the future, we will extend these checks to require that p1 effective
group membership must be a superset of p2 effective group membership.

Remove comment about setting error for reads on EOF, read returns 0 on
EOF so the code should be ok.
Remove non-effective priority boost, PRIO+1 doesn't do anything
(according to McKusick), if a real priority boost is needed it should
have been +4.
Style fixes:
.) return foo -> return (foo)
.) FLAG1|FlAG2 -> FLAG1 | FlAG2
.) wrap long lines

.) for(i=0;i=foo;i++) -> for (i = 0; i=foo; i++)
.) remove braces for some conditionals with a single statement
.) fix continuation lines.
md5 couldn't verify the binary because some code had to

This should really be spelt ipencap (as /etc/protocols does),
but a precedent has already been set by the ipproto array in
setkey.c.
It would be nice if /etc/protocols was parsed for the upperspec
field, but I don't do yacc/lex...
This change allows policies that only encrypt the encapsulated
packets passing between the endpoints of a gif tunnel. Setting
such a policy means that you can still talk directly (and
unencrypted) between the public IP numbers with (say) ssh.
