2012-02-06mac80211: move managed mode station state modificationJohannes Berg
Move the station state modification right before insert, this just makes the current code more readable (you can tell that it's before insertion looking at a single screenful of code) right now, but some upcoming changes will require this.

2012-02-06SUNRPC: Adding status trace pointsSteve Dickson
This patch adds three trace points to the status routines in the sunrpc state machine. The goal of these trace points is to give an Admin the ability to check on binding status or connection status to see if there is a potential problem.

2012-02-04tcp_v4_send_reset: binding oif to iif in no sock caseShawn Lu
Binding RST packet outgoing interface to incoming interface for tcp v4 when there is no socket associate with it. when sk is not NULL, using sk->sk_bound_dev_if instead. (suggested by Eric Dumazet). This has few benefits: 1. tcp_v6_send_reset already did that. 2. This helps tcp connect with SO_BINDTODEVICE set. When connection is lost, we still able to sending out RST using same interface. 3. we are sending reply, it is most likely to be succeed if iif is used Signed-off-by: Shawn Lu <shawn.lu@ericsson.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2012-02-04ipvs: fix matching of fwmark templates during schedulingSimon Horman
Commit f11017ec2d1859c661f4e2b12c4a8d250e1f47cf (2.6.37) moved the fwmark variable in subcontext that is invalidated before reaching the ip_vs_ct_in_get call. As vaddr is provided as pointer in the param structure make sure the fwmark variable is in same context. As the fwmark templates can not be matched, more and more template connections are created and the controlled connections can not go to single real server.

2012-02-02ceph: initialize client debugfs outside of monc->mutexSage Weil
Initializing debufs under monc->mutex introduces a lock dependency for sb->s_type->i_mutex_key, which (combined with several other dependencies) leads to an annoying lockdep warning. There's no particular reason to do the debugfs setup under this lock, so move it out. It used to be the case that our first monmap could come from the OSD; that is no longer the case with recent servers, so we will reliably set up the client entry during the initial authentication. We don't have to worry about racing with debugfs teardown by ceph_debugfs_client_cleanup() because ceph_destroy_client() calls ceph_msgr_flush() first, which will wait for the message dispatch work to complete (and the debugfs init to complete).

Always use cfmuxl_remove_uplayer when removing a up-layer. cfmuxl_ctrlcmd() can be called independently and in parallel with cfmuxl_remove_uplayer(). The race between them could cause list_del_rcu to be called on a node which has been already taken out from the list. That lead to a (rare) crash on accessing poisoned node->prev inside list_del_rcu.

The argument is not used at all, and it's not necessary, because a specific callback handler of course knows which subsys it belongs to. Now only ->pupulate() takes this argument, because the handlers of this callback always call cgroup_add_file()/cgroup_add_files().

2012-02-01tcp: md5: RST: getting md5 key from listenerShawn Lu
TCP RST mechanism is broken in TCP md5(RFC2385). When connection is gone, md5 key is lost, sending RST without md5 hash is deem to ignored by peer. This can be a problem since RST help protocal like bgp to fast recove from peer crash. In most case, users of tcp md5, such as bgp and ldp, have listener on both sides to accept connection from peer. md5 keys for peers are saved in listening socket. There are two cases in finding md5 key when connection is lost: 1.Passive receive RST: The message is send to well known port, tcp will associate it with listner. md5 key is gotten from listener. 2.Active receive RST (no sock): The message is send to ative side, there is no socket associated with the message. In this case, finding listener from source port, then find md5 key from listener. we are not loosing sercuriy here: packet is checked with md5 hash. No RST is generated if md5 hash doesn't match or no md5 key can be found. Signed-off-by: Shawn Lu <shawn.lu@ericsson.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
