Subject: [PATCH net-next 0/4] Generic XDP improvements
Date: Mon, 21 Jun 2021 05:01:56 +0530 [thread overview]
Message-ID: <20210620233200.855534-1-memxor@gmail.com> (raw)
This small series makes some improvements to generic XDP mode and brings it
closer to native XDP. Patch 1 splits out generic XDP processing into reusable
parts, patch 2 implements generic cpumap support (details in commit) and patch 3
allows devmap bpf prog execution before generic_xdp_tx is called.
Patch 4 just updates a couple of selftests to adapt to changes in behavior (in
that specifying devmap/cpumap prog fd in generic mode is now allowed).
Kumar Kartikeya Dwivedi (4):
net: core: split out code to run generic XDP prog
net: implement generic cpumap
bpf: devmap: implement devmap prog execution for generic XDP
bpf: update XDP selftests to not fail with generic XDP
