Subject: net: Remove iocb argument from sendmsg and recvmsg

After TIPC doesn't depend on iocb argument in its internal
implementations of sendmsg() and recvmsg() hooks defined in proto
structure, no any user is using iocb argument in them at all now.
Then we can drop the redundant iocb argument completely from kinds of
implementations of both sendmsg() and recvmsg() in the entire
networking stack.

From 63159f29be1df7f93563a8a0f78c5e65fc844ed6 Mon Sep 17 00:00:00 2001
From: Ian Morris <ipm@chirality.org.uk>
Date: Sun, 29 Mar 2015 14:00:04 +0100
Subject: ipv6: coding style: comparison for equality with NULL

The ipv6 code uses a mixture of coding styles. In some instances check for NULL
pointer is done as x == NULL and sometimes as !x. !x is preferred according to
checkpatch and this patch makes the code consistent by adopting the latter
form.

No changes detected by objdiff.

From 53b24b8f94cb15e38e332db82177cf3f0f4df0c5 Mon Sep 17 00:00:00 2001
From: Ian Morris <ipm@chirality.org.uk>
Date: Sun, 29 Mar 2015 14:00:05 +0100
Subject: ipv6: coding style: comparison for inequality with NULL

The ipv6 code uses a mixture of coding styles. In some instances check for NULL
pointer is done as x != NULL and sometimes as x. x is preferred according to
checkpatch and this patch makes the code consistent by adopting the latter
form.

No changes detected by objdiff.

From 7026b1ddb6b8d4e6ee33dc2bd06c0ca8746fa7ab Mon Sep 17 00:00:00 2001
From: David Miller <davem@davemloft.net>
Date: Sun, 5 Apr 2015 22:19:04 -0400
Subject: netfilter: Pass socket pointer down through okfn().

On the output paths in particular, we have to sometimes deal with two
socket contexts.  First, and usually skb->sk, is the local socket that
generated the frame.

And second, is potentially the socket used to control a tunneling
socket, such as one the encapsulates using UDP.

We do not want to disassociate skb->sk when encapsulating in order
to fix this, because that would break socket memory accounting.

The most extreme case where this can cause huge problems is an
AF_PACKET socket transmitting over a vxlan device.  We hit code
paths doing checks that assume they are dealing with an ipv4
socket, but are actually operating upon the AF_PACKET one.
