I was just playing with af_packet and added some debugging there that prints out the len of all packets it gets (for a certain ifidx) That's confusing me even more now. I get [ 7650.792004] packet_recv eda9e8c0 (len=137) [ 7650.792015] snaplen(eda9e8c0)=137 [ 7650.792027] free eda9e8c0, len = 137 [ 7650.792031] new skb: eda9e540 [ 7650.792039] packet_recv eda9e8c0 (len=137) [ 7650.792044] snaplen(eda9e8c0)=137 [ 7650.792048] new skb: eda9e8c0 [ 7650.819464] packet_recv d1f4e9a0 (len=124) [ 7650.819478] snaplen(d1f4e9a0)=124 [ 7650.819489] free d1f4e9a0, len = 124 [ 7650.819493] new skb: d1f4e8c0 [ 7650.819502] packet_recv d1f4e9a0 (len=124) [ 7650.819507] snaplen(d1f4e9a0)=124 [ 7650.819511] new skb: d1f4e9a0 [ 7651.215631] packet_recv e9ecc2a0 (len=376) [ 7651.215645] snaplen(e9ecc2a0)=376 [ 7651.215657] free e9ecc2a0, len = 376 [ 7651.215662] new skb: ede04b60 [ 7651.215671] packet_recv e9ecc2a0 (len=376) [ 7651.215675] snaplen(e9ecc2a0)=376 [ 7651.215680] new skb: e9ecc2a0 [ 7651.760751] SKB BUG: Invalid truesize (528) len=357, sizeof(sk_buff)=176 528-176 is 352 which doesn't occur in that list... Maybe I should print it in mac80211. johannes
