Build Update for ddiproietto/ovs
-------------------------------------

Build: #35
Status: Failed

Duration: 17 minutes and 44 seconds
Commit: 6aa953c (userconntrack_20160516)
Author: Daniele Di Proietto
Message: conntrack: Track ICMP type and code.

>From the connection tracker perspective, an ICMP connection is a tuple
identified by source ip address, destination ip address and ICMP id.

While this allows basic ICMP traffic (pings) to work, it doesn't take
into account the icmp type: the connection tracker will allow
requests/replies in any directions.

This is improved by making the ICMP type and code part of the connection
tuple.  An ICMP echo request packet from A to B, will create a
connection that matches ICMP echo request from A to B and ICMP echo
replies from B to A.  The same is done for timestamp and info
request/replies, and for ICMPv6.

A new modules conntrack-icmp is implemented, to allow only "request"
types to create new connections.

Also, since they're tracked in both userspace and kernel
implementations, ICMP type and code are always printed in ct-dpif (a few
testcase are updated as a consequence).
