Revision 57031eb794906eea4e1c7b31dc1e2429c0af0c66 authored by Willem de Bruijn on 07 February 2017, 20:57:21 UTC, committed by David S. Miller on 08 February 2017, 18:56:37 UTC
Link layer protocols may unconditionally pull headers, as Ethernet does in eth_type_trans. Ensure that the entire link layer header always lies in the skb linear segment. tpacket_snd has such a check. Extend this to packet_snd. Variable length link layer headers complicate the computation somewhat. Here skb->len may be smaller than dev->hard_header_len. Round up the linear length to be at least as long as the smallest of the two.
