Pull networking fixes from David Miller:
1) There was a simplification in the ipv6 ndisc packet sending
attempted here, which avoided using memory accounting on the
per-netns ndisc socket for sending NDISC packets. It did fix some
important issues, but it causes regressions so it gets reverted here
too. Specifically, the problem with this change is that the IPV6
output path really depends upon there being a valid skb->sk
attached.
The reason we want to do this change in some form when we figure out
how to do it right, is that if a device goes down the ndisc_sk
socket send queue will fill up and block NDISC packets that we want
to send to other devices too. That's really bad behavior.
Hopefully Thomas can come up with a better version of this change.
2) Fix a severe TCP performance regression by reverting a change made
to dev_pick_tx() quite some time ago. From Eric Dumazet.
3) TIPC returns wrongly signed error codes, fix from Erik Hugne.
4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
skb->sk too early. Fix from Li Hongjun.
5) RAW ipv4 sockets can use the wrong routing key during lookup, from

6) Similar to #1 revert an older change that tried to use plain
alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner

Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.
(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)
This patch should also be applied to the 3.9 and 3.10 kernels.

While looking into MLDv1/v2 code, I noticed that bridging code does
not convert it's max delay into jiffies for MLDv2 messages as we do
in core IPv6' multicast code.
RFC3810, 5.1.3. Maximum Response Code says:
The Maximum Response Code field specifies the maximum time allowed
before sending a responding Report. The actual time allowed, called
the Maximum Response Delay, is represented in units of milliseconds,
and is derived from the Maximum Response Code as follows: [...]
As we update timers that work with jiffies, we need to convert it.

commit 8728c544a9 ("net: dev_pick_tx() fix") and commit
b6fe83e952 ("bonding: refine IFF_XMIT_DST_RELEASE capability")
are quite incompatible : Queue selection is disabled because skb
dst was dropped before entering bonding device.
This causes major performance regression, mainly because TCP packets
for a given flow can be sent to multiple queues.
This is particularly visible when using the new FQ packet scheduler
with MQ + FQ setup on the slaves.
We can safely revert the first commit now that 416186fbf8
("net: Split core bits of netdev_pick_tx into __netdev_pick_tx")
properly caps the queue_index.

This reverts commit 1f324e3887.
It seems to cause regressions, and in particular the output path
really depends upon there being a socket attached to skb->sk for
checks such as sk_mc_loop(skb->sk) for example. See ip6_output_finish2().

Since commit 3d7b46cd20 (ip_tunnel: push generic protocol handling to
ip_tunnel module.), an Oops is triggered when an xfrm policy is configured on
an IPv4 over IPv4 tunnel.
xfrm4_policy_check() calls __xfrm_policy_check2(), which uses skb_dst(skb). But
this field is NULL because iptunnel_pull_header() calls skb_dst_drop(skb).

Should a connect fail, if the publication/server is unavailable or
due to some other error, a positive value will be returned and errno
is never set. If the application code checks for an explicit zero
return from connect (success) or a negative return (failure), it
will not catch the error and subsequent send() calls will fail as
shown from the strace snippet below.
socket(0x1e /* PF_??? */, SOCK_SEQPACKET, 0) = 3
connect(3, {sa_family=0x1e /* AF_??? */, sa_data="\2\1\322\4\0\0\322\4\0\0\0\0\0\0"}, 16) = 111
sendto(3, "test", 4, 0, NULL, 0) = -1 EPIPE (Broken pipe)
The reason for this behaviour is that TIPC wrongly inverts error
codes set in sk_err.

In commit 90ba9b19 (tcp: tcp_make_synack() can use alloc_skb()), Eric changed
the call to sock_wmalloc in tcp_make_synack to alloc_skb. In doing so,
the netfilter owner match lost its ability to block the SYNACK packet on
outbound listening sockets. Revert the change, restoring the owner match
functionality.

Currently we would still potentially suffer multicast packet loss if there
is just either an IGMP or an MLD querier: For the former case, we would
possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is
because we are currently assuming that if either an IGMP or MLD querier
is present that the other one is present, too.
This patch makes the behaviour and fix added in
"bridge: disable snooping if there is no querier" (b00589af3b)
to also work if there is either just an IGMP or an MLD querier on the
link: It refines the deactivation of the snooping to be protocol
specific by using separate timers for the snooped IGMP and MLD queries
as well as separate timers for our internal IGMP and MLD queriers.

Pull cgroup fix from Tejun Heo:
"During the percpu reference counting update which was merged during
v3.11-rc1, the cgroup destruction path was updated so that a cgroup in
the process of dying may linger on the children list, which was
necessary as the cgroup should still be included in child/descendant
iteration while percpu ref is being killed.
Unfortunately, I forgot to update cgroup destruction path accordingly
and cgroup destruction may fail spuriously with -EBUSY due to
lingering dying children even when there's no live child left - e.g.
"rmdir parent/child parent" will usually fail.
This can be easily fixed by iterating through the children list to
verify that there's no live child left. While this is very late in
the release cycle, this bug is very visible to userland and I believe
the fix is relatively safe.
Thanks Hugh for spotting and providing fix for the issue"

Pull workqueue fix from Tejun Heo:
"This contains one fix which could lead to system-wide lockup on
!PREEMPT kernels. It's very late in the cycle but this definitely is
a -stable material.
The problem is that workqueue worker tasks may process unlimited
number of work items back-to-back without every yielding inbetween.
This usually isn't noticeable but a work item which re-queues itself
waiting for someone else to do something can deadlock with
stop_machine. stop_machine will ensure nothing else happens on all
other cpus and the requeueing work item will reqeueue itself
indefinitely without ever yielding and thus preventing the CPU from
entering stop_machine.
Kudos to Jamie Liu for spotting and diagnosing the problem. This can
be trivially fixed by adding cond_resched() after processing each work
item"
