Max Laier fe2f7b3b0d Defer ip_output of pfsync updates to an independent callout thread instead
of just dropping the lock around the ip_output call.  This used to cause
corrupted state tree walks for some call-paths.

In a second stage all callouts will be marked MPSAFE according to the
setting of mpsafenet.

Brooks Davis fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

Gleb Smirnoff 2fa088e969 Fix error in synproxy connection completion. Source and
destination windows were confused, one instead of other.
This error was masked, because first segment of just
established connection is usually smaller than initially
announced window, and it was successfully passed. First
window reannouncement corrected erroneous 'seqhi' value.
The error showed up when client connected to synproxy
with zero initial window, and reannounced it after
session establishment.

(when the replacement is a table and no other criterion implies one AF).
In this case, pf would fail to select a replacement address and drop the

Daniel Hartmeier 2726bbe221 Initialise init_addr in pf_map_addr() in the PF_POOL_ROUNDROBIN,
prevents a possible endless loop in pf_get_sport() with 'static-port'

ICMP state entries use the ICMP ID as port for the unique state key. When
checking for a usable key, construct the key in the same way. Otherwise,
a colliding key might be missed or a state insertion might be refused even
though it could be inserted. The second case triggers the endless loop,
possibly allowing a NATed LAN client to lock up the kernel.

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.

Max Laier 4758aa2bd4 Reactivate skipping over bogus IPCP addresses on ppp interfaces. Be more
careful with the skip condition this time. Addresses are only not taken into
account if:
	- The interface is POINTTOPOINT
	- There is no route installed for the address
	- The user specified noalias (:0)
and	- We are looking at an IPv4 address.

This should be enough paranoia to not cause any false positives.

Max Laier f78086efb6 Move pf* init from SI_SUB_PSEUDO to SI_SUB_PROTO_IFATTACHDOMAIN where it is
save to call if_attachdomain from if_attach() (as done for if_loop.c). We
will now end up with a properly initialized if_afdata array and the nd6
callout will no longer try to deref a NULL pointer.

Still this is a temp workaround and the locking for if_afdata should be
revisited at a later point.

Max Laier c9f6794e2e One more round on the H/W supported checksum code: Fix NICs that can't do
the pseudo header. We really need the TCP packet length here. This happens
to end up in ip->ip_len in tcp_input.c, but here we should get it from the
len function variable instead.

Nate Lawson aaff1d4cfa Add a padding member to the header overlaid on data allocated in the
ACPI_DEBUG case.  Without this, use of allocated memory is unaligned and
causes a trap on ia64.  Intel may fix this differently in a subsequent
release but this is adequate for now.

David Malone 1f44b0a1b5 Get rid of the RANDOM_IP_ID option and make it a sysctl. NetBSD
have already done this, so I have styled the patch on their work:

        1) introduce a ip_newid() static inline function that checks
        the sysctl and then decides if it should return a sequential
        or random IP ID.

        2) named the sysctl net.inet.ip.random_id

        3) IPv6 flow IDs and fragment IDs are now always random.
        Flow IDs and frag IDs are significantly less common in the
        IPv6 world (ie. rarely generated per-packet), so there should
        be smaller performance concerns.

The sysctl defaults to 0 (sequential IP IDs).

Robert Watson 9baf5f2da1 Since if_oltr doesn't contain locking or run with INTR_MPSAFE, mark
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Max Laier 01105bbf3b Loopback fix from Daniel Hartmeier:
pf_cksum_fixup() was called without last argument from
	normalization, also fixup checksum when random-id modifies ip_id.
	This would previously lead to incorrect checksums for packets
	modified by scrub random-id.
