[GIT]: Networking

1) nf_conntrack_sip has a local variable marked static
unintentionally, for a function callable in parallel by
multiple threads this is very bad. Fix from Alexey Dobriyan.

2) GRE conntrack module's keymap list has bad locking leading to OOPS.
Fix by Alexey Dobriyan.

3) GRE conntrack module kfree()'s list head member of structure instead
of structure itself, yikes... Fixed by Alexey Dobriyan.

4) Potential remote exploit issue, IRC conntrack module blindly parses
strings in protocol packets assuming there is zero termination
there somewhere. We likely hit a zero byte anyways in the post
skb->data area since thats where skb_shared_info() sits, but that
is not something to rely upon at all. Fix from Patrick McHardy.

5) Denys Fedoryshchenko reports that his interfaces generally wedge
after some time, and this has happened since early 2.6.27-rcX
releases. Jarek Poplawski figured out that when net_tx_action()
races with dev_deactivate() the __QDISC_STATE_SCHED bit is left
set, and this causes dev_deactivate() to loop forever in a sleeping
state bit test.

6) Timewait socket handling under namespaces can lead to an OOPS
simply because we don't purge the timewait sockets attached to that
namespace from the hash tables when the namespace goes down.
Reproducer for the OOPS included in the commit message. Fix from
Daniel Lezcano.

7) Reported excessive ksoftirqd cpu utilization was tracked down to
allowing bridge hello timers smaller than 1 second, fixed by
Stephen Hemminger.

Please pull, thanks a lot!
