ipv6: Consolidate route lookup sequences.
Route lookups follow a general pattern in the ipv6 code wherein
we first find the non-IPSEC route, potentially override the
flow destination address due to ipv6 options settings, and then
finally make an IPSEC search using either xfrm_lookup() or
__xfrm_lookup().
__xfrm_lookup() is used when we want to generate a blackhole route
if the key manager needs to resolve the IPSEC rules (in this case
-EREMOTE is returned and the original 'dst' is left unchanged).
Otherwise plain xfrm_lookup() is used and when asynchronous IPSEC
resolution is necessary, we simply fail the lookup completely.
All of these cases are encapsulated into two routines,
ip6_dst_lookup_flow and ip6_sk_dst_lookup_flow. The latter of which
handles unconnected UDP datagram sockets.

udp: Add lockless transmit path
The UDP transmit path has been running under the socket lock
for a long time because of the corking feature. This means that
transmitting to the same socket in multiple threads does not
scale at all.
However, as most users don't actually use corking, the locking
can be removed in the common case.
This patch creates a lockless fast path where corking is not used.
Please note that this does create a slight inaccuracy in the
enforcement of socket send buffer limits. In particular, we
may exceed the socket limit by up to (number of CPUs) * (packet
size) because of the way the limit is computed.
As the primary purpose of socket buffers is to indicate congestion,
this should not be a great problem for now.

This patch adds the helper ip_make_skb which is like ip_append_data

ip_send_skb, which the transport protocol can call after it has
tweaked the skb.
It is meant to be called in cases where corking is not used should
have a one-to-one correspondence to sendmsg.
This patch also adds the helper ip_finish_skb which is meant to
be replace ip_push_pending_frames when corking is required.
Previously the protocol stack would peek at the socket write
queue and add its header to the first packet. With ip_finish_skb,
the protocol stack can directly operate on the final skb instead,

netfilter: nf_ct_tcp: fix out of sync scenario while in SYN_RECV
This patch fixes the out of sync scenarios while in SYN_RECV state.
Quoting Jozsef, what it happens if we are out of sync if the
following:
> > b. conntrack entry is outdated, new SYN received
> > - (b1) we ignore it but save the initialization data from it
> > - (b2) when the reply SYN/ACK receives and it matches the saved data,
> > we pick up the new connection
This is what it should happen if we are in SYN_RECV state. Initially,
the SYN packet hits b1, thus we save data from it. But the SYN/ACK
packet is considered a retransmission given that we're in SYN_RECV
state. Therefore, we never hit b2 and we don't get in sync. To fix
this, we ignore SYN/ACK if we are in SYN_RECV. If the previous packet
was a SYN, then we enter the ignore case that get us in sync.
This patch helps a lot to conntrackd in stress scenarios (assumming a
client that generates lots of small TCP connections). During the failover,
consider that the new primary has injected one outdated flow in SYN_RECV
state (this is likely to happen if the conntrack event rate is high
because the backup will be a bit delayed from the primary). With the
current code, if the client starts a new fresh connection that matches
the tuple, the SYN packet will be ignored without updating the state
tracking, and the SYN+ACK in reply will blocked as it will not pass
checkings III or IV (since all state tracking in the original direction
is not initialized because of the SYN packet was ignored and the ignore
case that get us in sync is not applied).
I posted a couple of patches before this one. Changli Gao spotted
a simpler way to fix this problem. This patch implements his idea.
