2303570fe8 ARP code reuses mbuf from ARP request to make a reply, but it does not
reset rcvif to NULL. Since rcvif is not NULL, ipfw(4) supposes that ARP
replies were received on specified interface.
Reset rcvif to NULL for ARP replies to fix this issue.

1171f21dab Modify the new NFSv4 client so that it appends a file handle
to the lock_owner4 string that goes on the wire. Also, add
code to do a ReleaseLockOwner Op on the lock_owner4 string
before a Close. Apparently not all NFSv4 servers handle multiple
instances of the same lock_owner4 string, at least not in a
compatible way. This patch avoids having multiple instances,
except for one unusual case, which will be fixed by a future commit.
Found at the recent NFSv4 interoperability Bakeathon.

- Use strlen(dp->d_name) instead of the unportable dp->d_namlen. Rename
  i to len to make it slightly more descriptive and prevent negative
  indexing of the array.
- Replace index() by strchr().

This supposedly fixes compilation on GNU systems.

df41287464 UltraSPARC-IV CPUs seem to be affected by a not publicly documented
erratum causing them to trigger stray vector interrupts accompanied by a
state in which they even fault on locked TLB entries. Just retrying the
instruction in that case gets the CPU back on track though. OpenSolaris
also just ignores a certain number of stray vector interrupts.
While at it, implement the stray vector interrupt handling for SPARC64-VI
which use these for indicating uncorrectable errors in interrupt packets.

4a35efc720 - For Cheetah- and Zeus-class CPUs don't flush all unlocked entries from
the TLBs in order to get rid of the user mappings but instead traverse
  them an flush only the latter like we also do for the Spitfire-class.
  Also flushing the unlocked kernel entries can cause instant faults which
  when called from within cpu_switch() are handled with the scheduler lock
  held which in turn can cause timeouts on the acquisition of the lock by
  other CPUs. This was easily seen with a 16-core V890 but occasionally
  also happened with 2-way machines.
  While at it, move the SPARC64-V support code entirely to zeus.c. This
  causes a little bit of duplication but is less confusing than partially
  using Cheetah-class bits for these.
- For SPARC64-V ensure that 4-Mbyte page entries are stored in the 1024-
  entry, 2-way set associative TLB.
- In {d,i}tlb_get_data_sun4u() turn off the interrupts in order to ensure
  that ASI_{D,I}TLB_DATA_ACCESS_REG actually are read twice back-to-back.

c412551667 Change the management of nested faults by switching to physical
addressing while reading or writing the trap frame. It's not
possible to guarantee that the one translation cache entry that
we depend on is not going to get purged by the CPU. We already
know that global shootdowns (ptc.g and/or ptc.ga) can (and will)
cause multiple TC entries to get purged and we initialize tried
to handle that by serializing kernel entry with these operations.
However, we need to serialize kernel exit as well.

But even if we can serialize, it appears that CPU threads within
a core can affect each other's TC entries beyond the global
shootdown. This would mean serializing any and all translatation
cache updates with the threads in a core with the kernel entry
and exit of any thread in that core. This is just too painful
and complicated.

Since we already properly coded for the 2 nested faults that we
can get, all we need to do is use those to obtain the physical
address of the trap frame, switch to physical mode and in that
way eliminate any further faults. The trap frame is already
aligned to 1KB boundaries to make sure we don't cross the page
boundary, this is safe to do.

We still need to serialize ptc.g or ptc.ga across CPUs because
the platform can only have 1 such operation outstanding at the
same time. We can now use a regular (spin) lock for this.

Also, it has been observed that we can get a nested TLB faults
for region 7 virtual addresses. This was unexpected. For now,
we enhance the nested TLB fault handler to deal with those as
well, but it needs to be understood.

6bbee8e28a Add a new option, OBJPR_NOTMAPPED, to vm_object_page_remove(). Passing this
option to vm_object_page_remove() asserts that the specified range of pages
is not mapped, or more precisely that none of these pages have any managed
mappings.  Thus, vm_object_page_remove() need not call pmap_remove_all() on
the pages.

This change not only saves time by eliminating pointless calls to
pmap_remove_all(), but it also eliminates an inconsistency in the use of
pmap_remove_all() versus related functions, like pmap_remove_write().  It
eliminates harmless but pointless calls to pmap_remove_all() that were being
performed on PG_UNMANAGED pages.

Update all of the existing assertions on pmap_remove_all() to reflect this
change.

f52efb6d38 Fix a corner case in STA beacon processing when a CSA is received but
the AP doesn't transmit beacons.

If the AP requests a CSA (ie, a channel switch) and then enters CAC
(channel availability check) for 60 seconds, it doesn't send beacons
and it just listens for radar events (and other things which we don't
do yet.)

Now, ath_newstate() was not resetting the beacon timer config on
a transition to the RUN state when in STA mode - it was setting
sc_syncbeacon, which simply updates the beacon config from the
contents of the next received beacon.

This means the STA never generates beacon miss events.

If the AP goes into CAC for 60 seconds and recovers, the STA will
happily receive the first beacon and reconfigure timers.
But if it gets a radar event after that, it'll change channel
again, not notify the station that it's changed channel..
and since the station is happily waiting for the first beacon
to configure the beacon timer details from, it won't ever
generate a beacon miss interrupt and it'll sit there forever
(or until the AP appears on that channel once again.)

This change forces the last known beacon timer config to be
written to hardware on a transition from CSA->RUN in STA mode.
This forces bmiss events to occur and the STA will eventually
(after a handful of beacon miss events) begin scanning for
another access point.

24c1c3bf71 We may split today's CAPABILITIES into CAPABILITY_MODE (which has
to do with global namespaces) and CAPABILITIES (which has to do with
constraining file descriptors). Just in case, and because it's a better
name anyway, let's move CAPABILITIES out of the way.

Also, change opt_capabilities.h to opt_capsicum.h; for now, this will
only hold CAPABILITY_MODE, but it will probably also hold the new
CAPABILITIES (implying constrained file descriptors) in the future.

2bddeb8538 In case ntp cannot resolve a hostname on startup it will queue the entry
for resolving by a child process that, upon success, will add the entry
to the config of the running running parent process.

Unfortunately there are a couple of bugs with this, fixed in various
later versions of upstream in potentially different ways due to other
code changes:

1) Upon server [-46] <FQDN> the [-46] are used as FQDN for later resolving
   which does not work.  Make sure we always pass the name (or IP there).

2) The intermediate file to carry the information to the child process
   does not know about -4/-6 restrictions, so that a dual-stacked host
   could resolve to an IPv6 address but that might be unreachable (see
   r223626) leading to no working synchronization ignoring a IPv4 record.
   Thus alter the intermediate format to also pass the address family
   (AF_UNSPEC (default), AF_INET or AF_INET6) to the child process
   depending on -4 or -6.

3) Make the child process to parse the new intermediate file format and
   save the address family for getaddrinfo() hints flags.

4) Change child to always reload resolv.conf calling res_init() before
   trying to resolve names.  This will pick up resolv.conf changes or
   new resolv.confs should they have not existed or been empty or
   unusable on ntp startup.  This fix is more conditional in upstream
   versions but given FreeBSD has res_init there is no need for the
   configure logic as well.
