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 includes new handling of IPv4 and IPv6 fragments, support for conntrack labels, and tracking connections via helpers. The kernel module tests distributed with the corresponding OVS userspace check a variety of scenarios implementing one-way firewalls, two-way firewalls, with and without IP fragments, VLANs and VXLAN tunnels, and in conjunction with FTP helpers, for both IPv4 and IPv6 traffic. This functionality is enabled through the CONFIG_OPENVSWITCH_CONNTRACK option. The branch below has been updated with the corresponding userspace pieces: https://github.com/justinpettit/ovs conntrack Joe Stringer (8): openvswitch: Scrub packet in ovs_vport_receive() openvswitch: Serialize acts with original netlink len openvswitch: Move MASKED* macros to datapath.h ipv6: Export nf_ct_frag6_gather() openvswitch: Add conntrack action netfilter: Always export nf_connlabels_replace() openvswitch: Allow matching on conntrack label openvswitch: Allow attaching helpers to ct action Justin Pettit (1): openvswitch: Allow matching on conntrack mark include/uapi/linux/openvswitch.h | 49 +++ net/ipv6/netfilter/nf_conntrack_reasm.c | 1 + net/netfilter/nf_conntrack_labels.c | 2 - net/openvswitch/Kconfig | 12 + net/openvswitch/Makefile | 1 + net/openvswitch/actions.c | 224 ++++++++-- net/openvswitch/conntrack.c | 758 ++++++++++++++++++++++++++++++++ net/openvswitch/conntrack.h | 128 ++++++ net/openvswitch/datapath.c | 70 ++- net/openvswitch/datapath.h | 12 + net/openvswitch/flow.c | 5 + net/openvswitch/flow.h | 9 + net/openvswitch/flow_netlink.c | 103 ++++- net/openvswitch/flow_netlink.h | 4 +- net/openvswitch/vport.c | 4 + 15 files changed, 1317 insertions(+), 65 deletions(-) create mode 100644 net/openvswitch/conntrack.c create mode 100644 net/openvswitch/conntrack.h -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
