Radeon memmap code, which with a new DDX driver and DRI drivers should fix
long-term stability issues with Radeons. Also adds support for r200's
ATI_fragment_shader, r300 texrect support and texture caching fixes, i915
vblank support and bugfixes, and new PCI IDs.
net.inet.ipsec.test_replay - When set to 1, IPsec will send packets with
the same sequence number. This allows to verify if the other side
has proper replay attacks detection.
net.inet.ipsec.test_integrity - When set 1, IPsec will send packets with
corrupted HMAC. This allows to verify if the other side properly
detects modified packets.
I used the first one to discover that we don't have proper replay attacks
detection in ESP (in fast_ipsec(4)).
natm_usr_detach(), which actually does the right thing. This code has
never worked properly, but also was never invoked since we only abort
connections associated with listen sockets, and netnam doesn't support
listen sockets.

reference. For now, we allow the possibility that the in_ppcb
pointer in the inpcb may be NULL if a timewait socket has had its
tcptw structure recycled. This allows tcp_timewait() to
consistently unlock the inpcb.

as being undocumented in Stevens, and was broken in 1997 during network
stack infrastructure work. It is the one remaining (and incorrect)
direct protocol reference to raw_usrreq.pru_attach; this is incorrect
because the raw socket code assumes that raw_uattach is called only after
the protocol has allocated a PCB.

protocols invoke after allocating a PCB, so so_pcb should be non-NULL.
It is only used by the two IPSEC implementations, so I didn't hit it in
my testing.

The real problem was that ioctl handlers needed to call amr_wait_command()
with the list lock held. This not only solves the completion race, it also
prevents bounce buffer corruption that could arise from amr_start() being
called without the proper locks held.

the completion of the command can occur before tsleep is called and
the command ends up blocking forever since the wakeup has already
been called.

error on the request. Add a wrapper, gctl_set_param_err(), that
sets the error on the request from the error returned by
gctl_set_param() and update current callers of gctl_set_param()
to call gctl_set_param_err() instead.
This makes gctl_set_param() much more usable in situations where
the caller knows better what to do with certain (apparent) error
conditions and setting an error on the request is not one of the
things that need to be done.

This entry point can be utilized by various Mandatory Access Control policies
so they can properly initialize the label of files which get created
as a result of an NFS operation. This work will be useful for fixing kernel
panics associated with accessing un-initialized or invalid vnode labels.
The implementation of these entry points will come shortly.

- If we know this CPU has a FPU via cpuid, then just assume the INT16
interface and make the npx device quiet to not clutter the dmesg. This
is true for all Pentium and later CPUs and even some of the later 486dx

new chips and improves support for already supported ones.
Some details, important for future merges:
- if_em.c merged manually, viewing diff between new vendor
driver and previous one.
- if_em_hw.h dropped in from vendor, and then restored revisions
1.16, 1.17, 1.18.
- if_em_hw.c dropped in from vendor, and then two liner change made,
that restores support for two rare chips.

infrastructure in place to do RX side, but that requires more study
before it can be done.
so that we only have to do an ioapic_write() instead of an ioapic_read()
followed by an ioapic_write() every time we mask and unmask level triggered
interrupts. This cuts the execution time for these operations roughly in
half.

PCI devices apparently was changed from a special deferred trap with TPC
pointing to the membar #Sync following the failing load/store instruction
to a precise trap with TPC pointing to the failing load/store instruction.
Thus remove the check the check whether TPC points to a membar #Sync in
case of a data access trap as it's off-by-one for USIII CPUs and it should
be sufficient to check whether the trap happend while in fasword*() to
properly detect traps caused by peeking/poking. This also corresponds to
what other OSs do. Note that also only the USIIi manual suggests to check
the TPC for such traps while the USII one doesn't (in the public USIII
manual device peeking/poking isn't mentioned at all).
NULL. We currently do allow this to happen, but may want to remove that
possibility in the future. This case can occur when a socket is left
open after TCP wraps up, and the timewait state is recycled. This will
be cleaned up in the future.
