Subject: [PATCH net-next v4 0/3] virtio_net: add optional flow dissection in virtio_net_hdr_to_skb
Date: Tue, 8 Jun 2021 13:02:21 -0400 [thread overview]
Message-ID: <20210608170224.1138264-1-tannerlove.kernel@gmail.com> (raw)
From: Tanner Love <tannerlove@google.com>
First patch extends the flow dissector BPF program type to accept
virtio-net header members.
Second patch uses this feature to add optional flow dissection in
virtio_net_hdr_to_skb(). This allows admins to define permitted
packets more strictly, for example dropping deprecated UDP_UFO
packets.
Third patch extends kselftest to cover this feature.
Tanner Love (3):
net: flow_dissector: extend bpf flow dissector support with vnet hdr
virtio_net: add optional flow dissection in virtio_net_hdr_to_skb
selftests/net: amend bpf flow dissector prog to do vnet hdr validation
