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. Signed-off-by: NDavid S.

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 converts UDP to use the new ip_finish_skb API. This would then allows us to more easily use ip_make_skb which allows UDP to run without a socket lock.

This patch adds the helper ip_make_skb which is like ip_append_data and ip_push_pending_frames all rolled into one, except that it does not send the skb produced. The sending part is carried out by 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, just like the non-corking case with ip_make_skb.

In order to allow simultaneous calls to ip_append_data on the same socket, it must not modify any shared state in sk or inet (other than those that are designed to allow that such as atomic counters). This patch abstracts out write references to sk and inet_sk in ip_append_data and its friends so that we may use the underlying code in parallel.

Many users have wanted the old functionality that was lost to be able to use pfifo as inner qdisc for netem. The reason that netem could not be classful with the older API was because of the limitations of the old dequeue/requeue interface; now that qdisc API has a peek function, there is no longer a problem with using any inner qdisc's.

ip_route_newports() is the only place in the entire kernel that cares about the port members in the routing cache entry's lookup flow key. Therefore the only reason we store an entire flow inside of the struct rtentry is for this one special case. Rewrite ip_route_newports() such that: 1) The caller passes in the original port values, so we don't need to use the rth->fl.fl_ip_{s,d}port values to remember them. 2) The lookup flow is constructed by hand instead of being copied from the routing cache entry's flow.
