With this commit, OVS will match the data in the RARP packets having
ethertype 0x8035, in the same way as the data in the ARP packets.

We currently only extract the ARP payload if the opcode indicates
that it is a request or reply. However, we also only set the
key length in these situations even though it should still be
possible to match on the opcode. There's no real reason to
restrict the ARP opcode since all have the same format so this
simply removes the check.

The callback function of call_rcu() just calls a kfree(), so we
can use kfree_rcu() instead of call_rcu() + callback function.
spatch with a semantic match is used to found this problem.

We currently check that a packet is IPv4 and TCP before fetching the
TCP flags. This enables fetching from IPv6 packets as well.
Reported-by: Michael Mao <mmao@nicira.com>
Signed-off-by: Jesse Gross <jesse@nicira.com>
When collecting TCP flags we check that the IP header indicates that
a TCP header is present but not that the packet is actually long
enough to contain the header. This adds a check to prevent reading
off the end of the packet.
In practice, this is only likely to result in reading of bad data and
not a crash due to the presence of struct skb_shared_info at the end
of the packet.

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

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.
