openvswitch: Allow attaching helpers to ct action
Add support for using conntrack helpers to assist protocol detection. The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper to be used for this connection. If no helper is specified, then helpers will be automatically applied as per the sysctl configuration of net.netfilter.nf_conntrack_helper. The helper may be specified as part of the conntrack action, eg: ct(helper=ftp). Initial packets for related connections should be committed to allow later packets for the flow to be considered established. Example ovs-ofctl flows allowing FTP connections from ports 1->2: in_port=1,tcp,action=ct(helper=ftp,commit),2 in_port=2,tcp,ct_state=-trk,action=ct(recirc) in_port=2,tcp,ct_state=+trk-new+est,action=1 in_port=2,tcp,ct_state=+trk+rel,action=1 Signed-off-by: Joe Stringer <joestringer@nicira.com> Acked-by: Thomas Graf <tgraf@suug.ch> Acked-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S.
