Subject: [PATCH net-next v2 0/8] udp: GRO L4 improvements
Date: Thu, 25 Mar 2021 18:23:59 +0100 [thread overview]
Message-ID: <cover.1616692794.git.pabeni@redhat.com> (raw)
This series improves the UDP L4 - either 'forward' or 'frag_list' -
co-existence with UDP tunnel GRO, allowing the first to take place
correctly even for encapsulated UDP traffic.
The first for patches are mostly bugfixes, addressing some GRO
edge-cases when both tunnels and L4 are present, enabled and in use.
The next 3 patches avoid unneeded segmentation when UDP GRO
traffic traverses in the receive path UDP tunnels.
Finally, some self-tests are included, covering the relevant
GRO scenarios.
Even if most patches are actually bugfixes, this series is
targeting net-next, as overall it makes available a new feature.
v1 -> v2:
- restrict post segmentation csum fixup to the only the relevant pkts
- use individual 'accept_gso_type' fields instead of whole gso bitmask
(Willem)
- use only ipv6 addesses from test range in self-tests (Willem)
- hopefully clarified most individual patches commit messages
Paolo Abeni (8):
udp: fixup csum for GSO receive slow path
udp: skip L4 aggregation for UDP tunnel packets
udp: properly complete L4 GRO over UDP tunnel packet
udp: never accept GSO_FRAGLIST packets
vxlan: allow L4 GRO passthrough
geneve: allow UDP L4 GRO passthrou
bareudp: allow UDP L4 GRO passthrou
selftests: net: add UDP GRO forwarding self-tests
