2009-11-08xfrm: SAD entries do not expire correctly after suspend-resumeYury Polyanskiy
This fixes the following bug in the current implementation of net/xfrm: SAD entries timeouts do not count the time spent by the machine in the suspended state. This leads to the connectivity problems because after resuming local machine thinks that the SAD entry is still valid, while it has already been expired on the remote server. The cause of this is very simple: the timeouts in the net/xfrm are bound to the old mod_timer() timers. This patch reassigns them to the CLOCK_REALTIME hrtimer. I have been using this version of the patch for a few months on my machines without any problems. Also run a few stress tests w/o any issues. This version of the patch uses tasklet_hrtimer by Peter Zijlstra (commit 9ba5f0). This patch is against 2.6.31.4. Please CC me.

2009-11-08ipv6: udp: optimize unicast RX pathEric Dumazet
We first locate the (local port) hash chain head If few sockets are in this chain, we proceed with previous lookup algo. If too many sockets are listed, we take a look at the secondary (port, address) hash chain. We choose the shortest chain and proceed with a RCU lookup on the elected chain. But, if we chose (port, address) chain, and fail to find a socket on given address, we must try another lookup on (port, in6addr_any) chain to find sockets not bound to a particular IP. -> No extra cost for typical setups, where the first lookup will probabbly be performed. RCU lookups everywhere, we dont acquire spinlock. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-11-08udp: secondary hash on (local port, local address)Eric Dumazet
Extends udp_table to contain a secondary hash table. socket anchor for this second hash is free, because UDP doesnt use skc_bind_node : We define an union to hold both skc_bind_node & a new hlist_nulls_node udp_portaddr_node udp_lib_get_port() inserts sockets into second hash chain (additional cost of one atomic op) udp_lib_unhash() deletes socket from second hash chain (additional cost of one atomic op) Note : No spinlock lockdep annotation is needed, because lock for the secondary hash chain is always get after lock for primary hash chain.

2009-11-08net: Support specifying the network namespace upon device creation.Eric W. Biederman
There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: Eric W.

2009-11-08can: fix WARN_ON dump in net/core/rtnetlink.c:rtmsg_ifinfo()Wolfgang Grandegger
On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo() is thrown when the CAN device is registered due to insufficient skb space, as reported by various users. This patch adds the rtnl_link_ops "get_size" to fix the problem. I think this patch is required for more recent kernels as well, even if no WARN_ON dumps are triggered.
