This test exercises the rejection of a stream parser that resizes the skb,
which is the use-after-free path introduced when sk_skb programs gained
access to packet data. An earlier single-patch version of this work
carried a Fixes: tag pointing at that commit, and it appears to have been
dropped when the series was split into multiple patches.
Should this commit include:
Fixes: 8a31db561566 ("bpf: add access to sock fields and pkt data from sk_skb
programs")
