The summary of the changes: * fix VLAN handling in bpf_flow.c, we don't need to peek back and look at skb->vlan_present; add selftests * pass and use flow_keys->n_proto instead of skb->protocol * fix clamping of flow_keys->nhoff for packets with nhoff > 0 * prohibit access to most of the __sk_buff fields from BPF flow dissector progs; only data/data_end/flow_keys are allowed (all input is now passed via flow_keys) * finally, document BPF flow dissector program environment ==================== Acked-by: Willem de Bruijn Acked-by: Petar Penkov Signed-off-by: Daniel Borkmann --- a090dbf25c566a9db5b4a994f564a7fc6031c2ad
