commit 8728c544a9cbdc ("net: dev_pick_tx() fix") and commit
b6fe83e9525a ("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 416186fbf8c5b
("net: Split core bits of netdev_pick_tx into __netdev_pick_tx")
properly caps the queue_index.

This reverts commit 1f324e38870cc09659cf23bc626f1b8869e201f2.
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 3d7b46cd20e3 (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.
This closes netfilter bugzilla #847.

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" (b00589af3b04)
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.

If st_kim_start() fails registered protocols should be removed. This is
done by calling st_reg_complete(), which as comment states is called
with spin lock held. But in st_register() when st_kim_start fails it
is called without holding spin lock, creating possibility of concurrent
access to st_gdata data members.
Hold spin lock while calling st_reg_complete if st_kim_start() fails.

In usb_reset_and_verify_device(), hub_port_init() allocates a new bos
descriptor to hold the value read by the device. The new bos descriptor
has to be compared with the old one in order to figure out if device 's
firmware has changed in which case the device has to be reenumerated.
In the original code, none of the two descriptors was deallocated leading
to memory leaks.
This patch compares the old bos descriptor with the new one to detect change
in firmware and releases the newly allocated bos descriptor to prevent memory
leak.

25 ... 52: uV = (vsel - 24) * 50000 + 1500000;
= (vsel - 25) * 50000 + 1550000;
53 ... 55: uV = (vsel - 52) * 100000 + 2900000;
= (vsel - 53) * 100000 + 3000000;
56 ... 62: uV = 3300000;
tps65217_uv2_ranges:
0 ... 8: uV = vsel * 50000 + 1500000;
9 ... 13: uV = (vsel - 8) * 100000 + 1900000;

14 ... 31: uV = (vsel - 13) * 50000 + 2400000;
= (vsel - 14) * 50000 + 2450000;
The voltage tables are composed of linear ranges.
This patch converts this driver to use multiple linear ranges APIs.
In original code, voltage range for DCDC1 is 900000 ~ 1800000 and voltage range
for DCDC3 is 900000 ~ 1500000. This patch separates the range 25~52 in
tps65217_uv1_ranges table to two linear ranges: 25~30 and 31~52.
This change makes it possible to reuse the same linear_ranges table for DCDCx.

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"

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

Steffen Klassert says:
====================
This pull request fixes some issues that arise when 6in4 or 4in6 tunnels
are used in combination with IPsec, all from Hannes Frederic Sowa and a
null pointer dereference when queueing packets to the policy hold queue.
1) We might access the local error handler of the wrong address family if
6in4 or 4in6 tunnel is protected by ipsec. Fix this by addind a pointer
to the correct local_error to xfrm_state_afinet.
2) Add a helper function to always refer to the correct interpretation
of skb->sk.
3) Call skb_reset_inner_headers to record the position of the inner headers
when adding a new one in various ipv6 tunnels. This is needed to identify
the addresses where to send back errors in the xfrm layer.
4) Dereference inner ipv6 header if encapsulated to always call the
right error handler.
5) Choose protocol family by skb protocol to not call the wrong
xfrm{4,6}_local_error handler in case an ipv6 sockets is used
in ipv4 mode.
6) Partly revert "xfrm: introduce helper for safe determination of mtu"
because this introduced pmtu discovery problems.
7) Set skb->protocol on tcp, raw and ip6_append_data genereated skbs.
We need this to get the correct mtu informations in xfrm.
8) Fix null pointer dereference in xdst_queue_output.

Allocating skbs when sending out neighbour discovery messages
currently uses sock_alloc_send_skb() based on a per net namespace
socket and thus share a socket wmem buffer space.
If a netdevice is temporarily unable to transmit due to carrier
loss or for other reasons, the queued up ndisc messages will cosnume
all of the wmem space and will thus prevent from any more skbs to
be allocated even for netdevices that are able to transmit packets.
The number of neighbour discovery messages sent is very limited,
simply use alloc_skb() and don't depend on any socket wmem space any
longer.

A sendto() regression was bisected and found to start with commit
f8126f1d5136be1 (ipv4: Adjust semantics of rt->rt_gateway.)
The problem is that it tries to ARP-lookup the constructed packet's
destination address rather than the explicitly provided address.
Fix this using FLOWI_FLAG_KNOWN_NH so that given nexthop is used.

The zero value means that tsecr is not valid, so it's a special case.
tsoffset is used to customize tcp_time_stamp for one socket.
tsoffset is usually zero, it's used when a socket was moved from one
host to another host.
Currently this issue affects logic of tcp_rcv_rtt_measure_ts. Due to
incorrect value of rcv_tsecr, tcp_rcv_rtt_measure_ts sets rto to
TCP_RTO_MAX.
