net: use indirect call wrappers at GRO transport layer

2018-12-15T21:23:02Z

This avoids an indirect call in the receive path for TCP and UDP packets. TCP takes precedence on UDP, so that we have a single additional conditional in the common case. When IPV6 is build as module, all gro symbols except UDPv6 are builtin, while the latter belong to the ipv6 module, so we need some special care. v1 -> v2: - adapted to INDIRECT_CALL_ changes v2 -> v3: - fix build issue with CONFIG_IPV6=m Signed-off-by: Paolo Abeni Signed-off-by: David S.

net: Convert GRO SKB handling to list_head.

2018-06-26T02:33:04Z

Manage pending per-NAPI GRO packets via list_head. Return an SKB pointer from the GRO receive handlers. When GRO receive handlers return non-NULL, it means that this SKB needs to be completed at this time and removed from the NAPI queue. Several operations are greatly simplified by this transformation, especially timing out the oldest SKB in the list when gro_count exceeds MAX_GRO_SKBS, and napi_gro_flush() which walks the queue in reverse order.

gso: validate gso_type in GSO handlers

2018-01-22T21:01:30Z

Validate gso_type during segmentation as SKB_GSO_DODGY sources may pass packets where the gso_type does not match the contents. Syzkaller was able to enter the SCTP gso handler with a packet of gso_type SKB_GSO_TCPV4. On entry of transport layer gso handlers, verify that the gso_type matches the transport protocol.

tcp: cleanup static functions

tcp_fastopen_create_child() is static and should not be exported. tcp4_gso_segment() and tcp6_gso_segment() should be static. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: Remove gso_send_check as an offload callback

2014-09-26T04:22:47Z

The send_check logic was only interesting in cases of TCP offload and UDP UFO where the checksum needed to be initialized to the pseudo header checksum. Now we've moved that logic into the related gso_segment functions so gso_send_check is no longer needed. Signed-off-by: Tom Herbert Signed-off-by: David S. Miller

tcp: move logic out of tcp_v[64]_gso_send_check

2014-09-26T04:22:46Z

In tcp_v[46]_gso_send_check the TCP checksum is initialized to the pseudo header checksum using __tcp_v[46]_send_check. We can move this logic into new tcp[46]_gso_segment functions to be done when ip_summed != CHECKSUM_PARTIAL (ip_summed == CHECKSUM_PARTIAL should be the common case, possibly always true when taking GSO path). After this change tcp_v[46]_gso_send_check is no-op. Signed-off-by: Tom Herbert Acked-by: Eric Dumazet Signed-off-by: David S. Miller

net-gre-gro: Fix a bug that breaks the forwarding path

2014-07-16T21:45:26Z

Fixed a bug that was introduced by my GRE-GRO patch (bf5a755f5e9186406bbf50f4087100af5bd68e40 net-gre-gro: Add GRE support to the GRO stack) that breaks the forwarding path because various GSO related fields were not set. The bug will cause on the egress path either the GSO code to fail, or a GRE-TSO capable (NETIF_F_GSO_GRE) NICs to choke. The following fix has been tested for both cases. Signed-off-by: H.K.
