Florian Westphal says:

====================
The following set contains changes for your *net-next* tree:

- make conntrack ignore packets that are delayed (containing
  data already acked).  The current behaviour to flag them as INVALID
  causes more harm than good, let them pass so peer can send an
  immediate ACK for the most recent sequence number.
- make conntrack recognize when both peers have sent 'invalid' FINs:
  This helps cleaning out stale connections faster for those cases where
  conntrack is no longer in sync with the actual connection state.
- Now that DECNET is gone, we don't need to reserve space for DECNET
  related information.
- compact common 'find a free port number for the new inbound
  connection' code and move it to a helper, then cap number of tries
  the new helper will make until it gives up.
- replace various instances of strlcpy with strscpy, from Wolfram Sang.
