This change is needed to make the 520.pfdenied script find the new
blacklistd/* anchor points for reporting blocked traffic.

The blacklistd daemon expects to see a message on stdout, instead
of just relying on the exit value from any invoked programs.
Change the pf filtering to create multiple filters, attached under
a the "blacklist/*" anchor point. This prevents the filtering for
each port's filtering rule from overwriting the previously installed
filtering rule. Check for an existing filtering rule for each port,
so the installation of a given filtering rule only happens once.
Reinstalling the same rule resets the counters for the pf rule, and
we don't want that.

The tag fastroute came from ipf and was removed in OpenBSD in 2011. The code
allows to skip the in pfil hooks and completely removes the out pfil invoke,
albeit looking up a route that the IP stack will likely find on its own.
The code between IPv4 and IPv6 is also inconsistent and marked as "XXX"
for years.

Reduce the cost of TLB invalidation on x86 by using per-CPU completion flags
Reduce contention during TLB invalidation operations by using a per-CPU
completion flag, rather than a single atomically-updated variable.
On a Westmere system (2 sockets x 4 cores x 1 threads), dtrace measurements
show that smp_tlb_shootdown is about 50% faster with this patch; observations
with VTune show that the percentage of time spent in invlrng_single_page on an
interrupt (actually doing invalidation, rather than synchronization) increases
from 31% with the old mechanism to 71% with the new one. (Running a basic file
server workload.)

In the 10.3 EC2 images, there was not. EC2 seems to hang if you try to

These are older MIPS4kc parts from Atheros. They typically ran at
sub-200MHz and have 11bg, 11a, or 11abg wifi MAC/PHYs integrated.
This port is the initial non-wifi pieces required to bring up the
chip. I'll commit the redboot and other pieces later, and then
hopefully(!) wifi support will follow.

The setkey() and encrypt() functions are part of XSI, not the POSIX base
definitions. There is no strict requirement for us to provide these,
especially if we're only going to keep these around as undocumented
stubs. The same holds for des_setkey() and des_cipher().
Instead of providing functions that only generate warnings when linking,
simply disallow linking against them. The impact of this is relatively
low. It only causes two leaf ports to break. I'll see what I can do to
help out to get those fixed.

On machines with just the wrong amount of physical memory (enough to
have a lot of bufs, but not enough to use VM_FREELIST_DMA32) it is
possible for 32-bit address limited devices to have little to no
memory left when attaching, due to potentially large vfs bio configs
consuming all memory below 4GB not protected by VM_FREELIST_ISADMA.
This causes the 32-bit devices to allocate from VM_FREELIST_ISADMA,
leaving that freelist emtpy when ISA devices need DMAable memory.
Rather than decrease VM_DMA32_NPAGES_THRESHOLD, use the time honored
technique of putting initially allocated kernel data structs
at the end (or at least not the beginning) of memory.
Since this allocation is done at boot and is wired, is not freed,
so the system is low on 32-bit (and ISA) dma'ble memory forever.
So it is a good candidate to move above 4GB.
While here, remove an unneeded round_page() from kmem_malloc's size
argument as suggested by alc. The first thing kmem_malloc() does
is a round_page(size), so there is no need to do it before the call.

The sysctl cannot fail. If it does fail on some FreeBSD derivative or
after some future change, just abort() so that the problem will be found
and fixed.
It's preferable to provide an arc4random() function that cannot fail and
cannot return poor quality random data. While abort() is not normally
suitable for a library, it makes sense here.
