Subject: [PATCHv5 net-next 00/10] OVS conntrack support

The goal of this series is to allow OVS to send packets through the Linux
kernel connection tracker, and subsequently match on fields populated by
conntrack.

This version addresses the feedback from v4, mostly minor fixes, including
shifting the conntrack init into the per-namespace functions rather than
per-datapath and ensuring the ct_mark/ct_label attributes are re-serialized
when userspace dumps the actions. Users attempting to specify actions that set
ct_labels with a length longer than the supported length will now get flow
rejections. This series also rebases against the latest conntrack zone changes.

This functionality is enabled through the CONFIG_OPENVSWITCH_CONNTRACK option.

The branch below has been updated with the corresponding userspace pieces:
https://github.com/joestringer/ovs dev/ct_20150818

Joe Stringer (10):
  openvswitch: Serialize acts with original netlink len
  openvswitch: Move MASKED* macros to datapath.h
  ipv6: Export nf_ct_frag6_gather()
  dst: Add __skb_dst_copy() variation
  openvswitch: Add conntrack action
  openvswitch: Allow matching on conntrack mark
  netfilter: Always export nf_connlabels_replace()
  netfilter: connlabels: Export setting connlabel length
  openvswitch: Allow matching on conntrack label
  openvswitch: Allow attaching helpers to ct action
