This is\nprimary useful to crack open UDP encapsulations (like VXLAN, GUE) for\nthe purposes of parsing the encapsulated packet.\n\nItems in this patch set:\n- Constify skb argument to UDP lookup functions\n- Create new protocol case in __skb_dissect for ETH_P_TEB. This is based\n on the code in the GRE dissect function and the special handling in\n GRE can now be removed (it sets protocol to ETH_P_TEB and returns so\n goto proto_again is done)\n- Add infrastructure for protocol specific flow dissection offload\n- Add infrastructure to perform UDP flow dissection. Uses same model of\n GRO where a flow_dissect callback can be associated with a UDP\n socket\n- Use the infrastructure to support flow dissection of VXLAN and GUE\n\nTested:\n\nForced RPS to call flow dissection for VXLAN, FOU, and GUE. Observed\nthat inner packet was being properly dissected.\n\nTom Herbert (6):\n flow_dissector: Move ETH_P_TEB processing to main switch\n udp: Constify skb argument in lookup functions\n flow_dissector: Add protocol specific flow dissection offload\n udp: flow dissector offload\n fou: Support flow dissection\n vxlan: support flow dissect\n\n drivers/net/vxlan.c | 50 ++++++++++++\n include/linux/netdevice.h | 7 ++\n include/linux/udp.h | 8 ++\n include/net/flow_dissector.h | 9 +++\n include/net/ip.h | 2 +-\n include/net/sock_reuseport.h | 2 +-\n include/net/udp.h | 19 +++--\n include/net/udp_tunnel.h | 8 ++\n net/core/dev.c | 14 ++++\n net/core/flow_dissector.c | 176 +++++++++++++++++++++++++++++--------------\n net/core/sock_reuseport.c | 5 +-\n net/ipv4/fou.c | 63 ++++++++++++++++\n net/ipv4/route.c | 4 +-\n net/ipv4/udp.c | 11 +--\n net/ipv4/udp_offload.c | 45 +++++++++++\n net/ipv4/udp_tunnel.c | 1 +\n net/ipv6/udp.c | 10 +--\n net/ipv6/udp_offload.c | 13 ++++\n 18 files changed, 369 insertions(+), 78 deletions(-)" }
