Add pfcp module that allows to create a PFCP-type netdev. The netdev then can be passed to tc when creating a filter to indicate that PFCP filter should be created. To add a PFCP filter, a special netdev must be created and passed to tc command: ip link add pfcp0 type pfcp tc filter add dev eth0 ingress prio 1 flower pfcp_opts \ 1:123/ff:fffffffffffffff0 skip_hw action mirred egress redirect dev pfcp0 Changes in iproute2 are required to be able to add the pfcp netdev and use pfcp_opts in tc (patchset will be submitted later). ICE COMMS package is required as it contains PFCP profiles. Part of this patchset modifies IP_TUNNEL_*_OPTs, which were previously stored in a __be16. All possible values have already been used, making it impossible to add new ones. Alexander Lobakin (2): ip_tunnel: use a separate struct to store tunnel params in the kernel ip_tunnel: convert __be16 tunnel flags to bitmaps Marcin Szycik (2): ice: refactor ICE_TC_FLWR_FIELD_ENC_OPTS ice: Add support for PFCP hardware offload in switchdev Michal Swiatkowski (1): pfcp: always set pfcp metadata Wojciech Drewek (1): pfcp: add PFCP module drivers/net/Kconfig | 13 + drivers/net/Makefile | 1 + drivers/net/bareudp.c | 19 +- drivers/net/ethernet/intel/ice/ice_ddp.c | 9 + .../net/ethernet/intel/ice/ice_flex_type.h | 4 +- .../ethernet/intel/ice/ice_protocol_type.h | 12 + drivers/net/ethernet/intel/ice/ice_switch.c | 85 +++++ drivers/net/ethernet/intel/ice/ice_switch.h | 2 + drivers/net/ethernet/intel/ice/ice_tc_lib.c | 68 +++- drivers/net/ethernet/intel/ice/ice_tc_lib.h | 7 +- .../ethernet/mellanox/mlx5/core/en/tc_tun.h | 2 +- .../mellanox/mlx5/core/en/tc_tun_encap.c | 6 +- .../mellanox/mlx5/core/en/tc_tun_geneve.c | 12 +- .../mellanox/mlx5/core/en/tc_tun_gre.c | 9 +- .../mellanox/mlx5/core/en/tc_tun_vxlan.c | 9 +- .../net/ethernet/mellanox/mlx5/core/en_tc.c | 15 +- .../ethernet/mellanox/mlxsw/spectrum_ipip.c | 62 ++-- .../ethernet/mellanox/mlxsw/spectrum_ipip.h | 2 +- .../ethernet/mellanox/mlxsw/spectrum_span.c | 10 +- .../ethernet/netronome/nfp/flower/action.c | 26 +- drivers/net/geneve.c | 46 ++- drivers/net/pfcp.c | 307 ++++++++++++++++++ drivers/net/vxlan/vxlan_core.c | 14 +- include/linux/netdevice.h | 7 +- include/net/dst_metadata.h | 10 +- include/net/flow_dissector.h | 2 +- include/net/gre.h | 59 ++-- include/net/ip6_tunnel.h | 4 +- include/net/ip_tunnels.h | 106 +++++- include/net/pfcp.h | 83 +++++ include/net/udp_tunnel.h | 4 +- include/uapi/linux/if_tunnel.h | 36 ++ include/uapi/linux/pkt_cls.h | 14 + net/bridge/br_vlan_tunnel.c | 5 +- net/core/filter.c | 20 +- net/core/flow_dissector.c | 12 +- net/ipv4/fou_bpf.c | 2 +- net/ipv4/gre_demux.c | 2 +- net/ipv4/ip_gre.c | 148 +++++---- net/ipv4/ip_tunnel.c | 92 ++++-- net/ipv4/ip_tunnel_core.c | 83 +++-- net/ipv4/ip_vti.c | 43 ++- net/ipv4/ipip.c | 33 +- net/ipv4/ipmr.c | 2 +- net/ipv4/udp_tunnel_core.c | 5 +- net/ipv6/addrconf.c | 3 +- net/ipv6/ip6_gre.c | 87 ++--- net/ipv6/ip6_tunnel.c | 14 +- net/ipv6/sit.c | 47 ++- net/netfilter/ipvs/ip_vs_core.c | 6 +- net/netfilter/ipvs/ip_vs_xmit.c | 20 +- net/netfilter/nft_tunnel.c | 45 +-- net/openvswitch/flow_netlink.c | 55 ++-- net/psample/psample.c | 26 +- net/sched/act_tunnel_key.c | 39 +-- net/sched/cls_flower.c | 134 +++++++- 56 files changed, 1519 insertions(+), 469 deletions(-) create mode 100644 drivers/net/pfcp.c create mode 100644 include/net/pfcp.h
