The fix is to pass p_off parameter in *_gro_complete. Next, inner_network_header is always set in the receive phase of GRO, this is then leveraged in the next commit to remove some state from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be unnecessarily complicated due to encapsulation support in GRO. In addition, udpgro_fwd selftest is adjusted to include the socket lookup case for vxlan. This selftest will test its supposed functionality once local bind support is merged (https://lore.kernel.org/netdev/df300a49-7811-4126-a56a-a77100c8841b@gmail.com/). v1 -> v2: - Pass p_off in *_gro_complete to fix UDP bug - Remove more conditionals and memory fetches from inet_gro_flush - v1: https://lore.kernel.org/netdev/e1d22505-c5f8-4c02-a997-64248480338b@gmail.com/ Richard Gobert (4): net: gro: add p_off param in *_gro_complete selftests/net: add local address bind in vxlan selftest net: gro: set inner_network_header in receive phase net: gro: move L3 flush checks to tcp_gro_receive drivers/net/geneve.c | 7 +- drivers/net/vxlan/vxlan_core.c | 11 ++-- include/linux/etherdevice.h | 2 +- include/linux/netdevice.h | 3 +- include/linux/udp.h | 2 +- include/net/gro.h | 33 ++++++---- include/net/inet_common.h | 2 +- include/net/tcp.h | 6 +- include/net/udp.h | 8 +-- include/net/udp_tunnel.h | 2 +- net/8021q/vlan_core.c | 9 ++- net/core/gro.c | 5 +- net/ethernet/eth.c | 5 +- net/ipv4/af_inet.c | 53 ++------------- net/ipv4/fou_core.c | 9 +-- net/ipv4/gre_offload.c | 6 +- net/ipv4/tcp_offload.c | 80 ++++++++++++++++++----- net/ipv4/udp.c | 3 +- net/ipv4/udp_offload.c | 26 ++++---- net/ipv6/ip6_offload.c | 45 +++++-------- net/ipv6/tcpv6_offload.c | 7 +- net/ipv6/udp.c | 3 +- net/ipv6/udp_offload.c | 13 ++-- tools/testing/selftests/net/udpgro_fwd.sh | 10 ++- 24 files changed, 188 insertions(+), 162 deletions(-)
