743312367a VFS_STATFS(mp, ...) is mostly called with &mp->mnt_stat, but a few cases
doesn't.  Most of the implementations have grown weeds for this so they
copy some fields from mnt_stat if the passed argument isn't that.

Fix this the cleaner way:  Always call the implementation on mnt_stat
and copy that in toto to the VFS_STATFS argument if different.

061f5ec825 Fix null-pointer indirect function calls introduced in the previous
commit. In the new world order, the transitive closure on the vector
operations is not precomputed. As such, it's unsafe to actually use
any of the function pointers in an indirect function call. They can
be null, and we need to use the default vector in that case.
This is mostly a quick fix for the four function pointers that are
ed explicitly. A more generic or scalable solution is likely to see
the light of day.

tcpip_fillheaders()
  tcp_discardcb()

  tcp_new_isn()
  tcp_xmit_bandwidth_limit()

Fix a locking comment in tcp_twstart(): the pcbinfo will be locked (and

89924e5865 Pass the inpcb reference into ip_getmoptions() rather than just the
inp->inp_moptions pointer, so that ip_getmoptions() can perform
necessary locking when doing non-atomic reads.

Lock the inpcb by default to copy any data to local variables, then
unlock before performing sooptcopyout().

d8fed1d050 Correct a sanity check in vnode_pager_generic_putpages(). The cast used
to implement the sanity check should have been changed when we converted
the implementation of vm_pindex_t from 32 to 64 bits.  (Thus, RELENG_4 is
not affected.)  The consequence of this error would be a legimate write to
an extremely large file being treated as an errant attempt to write meta-
data.

993d9505d4 Start working through inpcb locking for ip_ctloutput() by cleaning up
modifications to the inpcb IP options mbuf:

- Lock the inpcb before passing it into ip_pcbopts() in order to prevent
  simulatenous reads and read-modify-writes that could result in races.
- Pass the inpcb reference into ip_pcbopts() instead of the option chain
  pointer in the inpcb.
- Assert the inpcb lock in ip_pcbots.
- Convert one or two uses of a pointer as a boolean or an integer
  comparison to a comparison with NULL for readability.

8092705059 IPv6 packets can contain headers (like options) before the TCP/UDP/ICMP6
header. pf finds the first TCP/UDP/ICMP6 header to filter by traversing
the header chain. In the case where headers are skipped, the protocol
checksum verification used the wrong length (included the skipped headers),
leading to incorrectly mismatching checksums. Such IPv6 packets with
headers were silently dropped.

18c3f40e94 Use "ifconfig -l" instead of "list_network_interfaces all" in
ifnet_rename() to support situations where rc.conf's $network_interfaces
variable is set to an explicit list of network interfaces (instead of
the default "auto").

Using "list_network_interfaces all" resulted in using
$network_interfaces for both interface _renaming_ and interface
_configuration_ which obviously cannot work either before (if the
new name is in $network_interfaces) or after (if the old name is in
$network_interfaces) renaming the interface.

9055ed836a o Don't limit GPT as a rank 2 provider. Allow it to be connected
anywhere in the DAG. This includes configurations that are not
   allowed by the EFI specification.
o  Reject a GPT partition table if it's not preceeded by a PMBR.
   There's no need to preserve the MBR partitioning anymore as GPT
   is mature and with the first bullet extending the applicability
   of GPT, it's better to be a bit more strict.

5d3d03f152 Grab Giant around calls to DEVICE_SUSPEND/RESUME in acpi_SetSleepState().
If we are resuming non-MPSAFE drivers, they need Giant held for them.
This may fix some obscure suspend/resume problems.  It has fixed keyrate
setting problems that were triggered by cardbus (MPSAFE) changing the
ordering for syscons resume (non-MPSAFE).  Also, add some asserts that
Giant is held in our suspend/resume and shutdown methods.
