David S. Miller b48b63a1f6 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	net/netfilter/nfnetlink_log.c
	net/netfilter/xt_LOG.c

Rather easy conflict resolution, the 'net' tree had bug fixes to make
sure we checked if a socket is a time-wait one or not and elide the
logging code if so.

Whereas on the 'net-next' side we are calculating the UID and GID from
the creds using different interfaces due to the user namespace changes
from Eric Biederman.

Eric W. Biederman 15e473046c netlink: Rename pid to portid to avoid confusion
It is a frequent mistake to confuse the netlink port identifier with a
process identifier.  Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.

I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.

I have successfully built an allyesconfig kernel with this change.

Jesse Gross 6081030769 Revert "openvswitch: potential NULL deref in sample()"
This reverts commit 5b3e7e6cb5.

The problem that the original commit was attempting to fix can
never happen in practice because validation is done one a per-flow
basis rather than a per-packet basis.  Adding additional checks at
runtime is unnecessary and inconsistent with the rest of the code.

Dan Carpenter 5b3e7e6cb5 openvswitch: potential NULL deref in sample()
If there is no OVS_SAMPLE_ATTR_ACTIONS set then "acts_list" is NULL and
it leads to a NULL dereference when we call nla_len(acts_list).  This
is a static checker fix, not something I have seen in testing.

Jesse Gross 81e5d41d7e openvswitch: Fix checksum update for actions on UDP packets.
When modifying IP addresses or ports on a UDP packet we don't
correctly follow the rules for unchecksummed packets.  This meant
that packets without a checksum can be given a incorrect new checksum
and packets with a checksum can become marked as being unchecksummed.
This fixes it to handle those requirements.

Jesse Gross ccb1352e76 net: Add Open vSwitch kernel components.
Open vSwitch is a multilayer Ethernet switch targeted at virtualized
environments.  In addition to supporting a variety of features
expected in a traditional hardware switch, it enables fine-grained
programmatic extension and flow-based control of the network.
This control is useful in a wide variety of applications but is
particularly important in multi-server virtualization deployments,
which are often characterized by highly dynamic endpoints and the need
to maintain logical abstractions for multiple tenants.

The Open vSwitch datapath provides an in-kernel fast path for packet
forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,
which is able to accept configuration from a variety of sources and
translate it into packet processing rules.

See http://openvswitch.org for more information and userspace
utilities.
