seeded with arc4random rather than calling arc4random for each
packet. Note this is the same algorithm used to select the IV when
doing WEP on the host.
o don't grab the mutex at the top of ath_detach; it does nothing
useful
o deal with entry to ath_ioctl during detach to disable promiscuous
mode as a result of calling bpfdetach2: cannot call ath_init when
the device is marked invalid as the code isn't prepared to deal
with it (in particular by that time the hal reference may have
been yanked)

use because a kernel thread is borrowing it. The borrowed page table
can change spontaneously, making any dependence on its continued use
subject to a race condition.
- _pmap_unwire_pte_hold() cannot use pmap_is_current(): If a change is
made to a page table page mapping for a borrowed page table, the TLB
must be updated.

you on the current queue. In the future, it would be nice if priority
propagation could deterministicly pluck a thread off of the next queue
and put it on the current queue. Until then this hack stops us from
holding up our entire current queue, including interrupt handlers, while
a thread on the next queue is blocked while holding Giant.
- Inherit our pctcpu information from our parent.
- correct signedness mixups.
- log fix.
- preparation for 64bit sequence number.
introduce SA id (unique ID for SA - SPI is useless as duplicated
SPI is allowed)
- no need to malloc/free cksum buffer.

kqueue write events on a socket and you regularly create tons of pipes
which overwrites the structure causing a panic when removing the knote
from the list. If the peer has gone away (and it's a write knote), then
don't bother trying to remove the knote from the list.

- Return NULL instead of returning memory outside of the stackgap
in stackgap_alloc() (FreeBSD-SA-00:42.linux)
- Check for stackgap_alloc() returning NULL in ibcs2_emul_find();
other calls to stackgap_alloc() have not been changed since they
are small fixed-size allocations.
- Replace use of strcpy() with strlcpy() in exec_coff_imgact()
to avoid buffer overflow
- Use strlcat() instead of strcat() to avoid a one byte buffer
overflow in ibcs2_setipdomainname()
- Use copyinstr() instead of copyin() in ibcs2_setipdomainname()
to ensure that the string is null-terminated
- Avoid integer overflow in ibcs2_setgroups() and ibcs2_setgroups()
by checking that gidsetsize argument is non-negative and
no larger than NGROUPS_MAX.
- Range-check signal numbers in ibcs2_wait(), ibcs2_sigaction(),
ibcs2_sigsys() and ibcs2_kill() to avoid accessing array past
the end (or before the start)
parameter in the read and write case dereferenced an unitialized
pointer and can't possibly ever have catched an actual invalid
argument.
This was apparently true for the read/write and getconf cases. The
latter does not even receive the paramter that is to be verified.
I'm surprised that this did not cause kernel panics, but it seems
that the uninitialized local variable happens to contain data that
may be used as a pointer to memory that satisfies the test condition.
Make the code work as intended by moving the test inside the switch
case where the pointer has been properly initialized.
Since the read and write case shared just about all code (except
for the single call to PCIB_READ_CONFIG resp. PCIB_WRITE_CONFIG) I
have merged both cases.

- Allocate storage for uap->msg always because it is copyin()'ed in
native sendmsg().
- Convert sockopt level from Linux to FreeBSD after native recvmsg() calling.
- Some cleanups.
