Subject: [PATCH net-next v7 0/3] virtio_net: add optional flow dissection in virtio_net_hdr_to_skb
Date: Wed, 16 Jun 2021 16:34:45 -0400 [thread overview]
Message-ID: <20210616203448.995314-1-tannerlove.kernel@gmail.com> (raw)
From: Tanner Love <tannerlove@google•com>
First patch extends the flow dissector BPF program type to accept
pointer to virtio-net header.
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.
