Date: Fri, 10 Jul 2015 16:19:02 +0200 From: Thomas Graf <tgraf@...g.ch> To: roopa@...ulusnetworks.com, rshearma@...cade.com, ebiederm@...ssion.com, hannes@...essinduktion.org, pshelar@...ira.com, jesse@...ira.com, davem@...emloft.net, daniel@...earbox.net, tom@...bertland.com, edumazet@...gle.com, jiri@...nulli.us, marcelo.leitner@...il.com, stephen@...workplumber.org, jpettit@...ira.com, kaber@...sh.net Cc: netdev@...r.kernel.org, dev@...nvswitch.org Subject: [RFC net-next 00/22] Lightweight & flow based tunneling This series combines the work previously posted by Roopa, Robert and myself. It's according to what we discussed at NFWS. The series accomplishes: * Lightweight tunnel infrastructure to attach encapsulation instructions to routes. * Metadata dst to carry metadata between forwarding elements. * Use of this new infrastructure in VXLAN and GRE to enable flow based RX/TX tunnels using iproute2 and to get rid of OVS specific vports. iproute examples: VXLAN: ip route add 40.1.1.1/32 encap vxlan id 10 dst 50.1.1.2 dev vxlan0 MPLS: ip route add 10.1.1.0/30 encap mpls 200 via inet 10.1.1.1 dev swp1 The series is functional for both iproute2 and OVS and demonstrates how a unified and combined code path can look like. Comments? Pravin Shelar (1): openvswitch: Use regular GRE net_device instead of vport Roopa Prabhu (9): rtnetlink: introduce new RTA_ENCAP_TYPE and RTA_ENCAP attributes lwtunnel: infrastructure for handling light weight tunnels like mpls ipv4: support for fib route lwtunnel encap attributes ipv6: support for fib route lwtunnel encap attributes lwtunnel: support dst output redirect function ipv4: redirect dst output to lwtunnel output ipv6: rt6_info output redirect to tunnel output mpls: export mpls functions for use by mpls iptunnels mpls: ip tunnel support Thomas Graf (12): ip_tunnel: Make ovs_tunnel_info and ovs_key_ipv4_tunnel generic dst: Metadata destinations arp: Inherit metadata dst when creating ARP requests vxlan: Flow based tunneling route: Extend flow representation with tunnel key route: Per route IP tunnel metadata via lightweight tunnel fib: Add fib rule match on tunnel id vxlan: Factor out device configuration openvswitch: Make tunnel set action attach a metadata dst openvswitch: Move dev pointer into vport itself openvswitch: Abstract vport name through ovs_vport_name() openvswitch: Use regular VXLAN net_device device drivers/net/vxlan.c | 671 +++++++++++++++++++++-------------- include/linux/lwtunnel.h | 6 + include/linux/mpls_iptunnel.h | 6 + include/linux/skbuff.h | 1 + include/net/dst.h | 5 +- include/net/dst_metadata.h | 55 +++ include/net/fib_rules.h | 1 + include/net/flow.h | 7 + include/net/ip6_fib.h | 3 + include/net/ip_fib.h | 5 +- include/net/ip_tunnels.h | 84 ++++- include/net/lwtunnel.h | 144 ++++++++ include/net/mpls_iptunnel.h | 29 ++ include/net/route.h | 1 + include/net/vxlan.h | 83 ++++- include/uapi/linux/fib_rules.h | 2 +- include/uapi/linux/if_link.h | 1 + include/uapi/linux/lwtunnel.h | 16 + include/uapi/linux/mpls_iptunnel.h | 28 ++ include/uapi/linux/openvswitch.h | 2 +- include/uapi/linux/rtnetlink.h | 17 + net/Kconfig | 7 + net/core/Makefile | 1 + net/core/dev.c | 7 +- net/core/dst.c | 76 +++- net/core/fib_rules.c | 17 +- net/core/lwtunnel.c | 228 ++++++++++++ net/ipv4/arp.c | 71 ++-- net/ipv4/fib_frontend.c | 8 + net/ipv4/fib_semantics.c | 101 +++++- net/ipv4/ip_gre.c | 165 ++++++++- net/ipv4/ip_input.c | 3 +- net/ipv4/ip_tunnel_core.c | 114 ++++++ net/ipv4/route.c | 26 +- net/ipv6/ip6_fib.c | 2 + net/ipv6/route.c | 34 +- net/mpls/Kconfig | 8 +- net/mpls/Makefile | 1 + net/mpls/af_mpls.c | 11 +- net/mpls/internal.h | 3 + net/mpls/mpls_iptunnel.c | 229 ++++++++++++ net/openvswitch/Kconfig | 12 - net/openvswitch/Makefile | 2 - net/openvswitch/actions.c | 12 +- net/openvswitch/datapath.c | 19 +- net/openvswitch/datapath.h | 5 +- net/openvswitch/dp_notify.c | 5 +- net/openvswitch/flow.c | 4 +- net/openvswitch/flow.h | 78 +--- net/openvswitch/flow_netlink.c | 81 ++++- net/openvswitch/flow_netlink.h | 3 +- net/openvswitch/vport-geneve.c | 17 +- net/openvswitch/vport-gre.c | 313 ---------------- net/openvswitch/vport-internal_dev.c | 38 +- net/openvswitch/vport-netdev.c | 272 +++++++++++--- net/openvswitch/vport-netdev.h | 13 - net/openvswitch/vport-vxlan.c | 322 ----------------- net/openvswitch/vport-vxlan.h | 11 - net/openvswitch/vport.c | 34 +- net/openvswitch/vport.h | 21 +- 60 files changed, 2292 insertions(+), 1249 deletions(-) create mode 100644 include/linux/lwtunnel.h create mode 100644 include/linux/mpls_iptunnel.h create mode 100644 include/net/dst_metadata.h create mode 100644 include/net/lwtunnel.h create mode 100644 include/net/mpls_iptunnel.h create mode 100644 include/uapi/linux/lwtunnel.h create mode 100644 include/uapi/linux/mpls_iptunnel.h create mode 100644 net/core/lwtunnel.c create mode 100644 net/mpls/mpls_iptunnel.c delete mode 100644 net/openvswitch/vport-gre.c delete mode 100644 net/openvswitch/vport-vxlan.c delete mode 100644 net/openvswitch/vport-vxlan.h -- 2.4.3 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
