netsniff-ng: Add dissector for Linux "cooked" packets
Added dissector_sll.c which uses sockaddr_ll to lookup & print higher L3 layer protocol. This dissector is mapped by LINKTYPE_LINUX_SLL link type. Sample output of dissected Netlink & Ethernet packets. Truncated manually some longer lines by "...": > nlmon0 20 1434193547s.717131169ns #6 [ Linux "cooked" Pkt Type 4 (outgoing), If Type 824 (netlink), Addr Len 0, Src (), Proto 0x0 ] [ NLMSG Family 0 (routing), Len 20, Type 0x0003 (DONE)... > wlp3s0 52 1434194181s.436224709ns #9 [ Linux "cooked" Pkt Type 4 (outgoing), If Type 1 (ether), Addr Len 6, Src (XX:XX:XX:XX:XX:XX), Proto 0x800 ] [ IPv4 Addr (XXX.XXX.XXX.XXX => 212.42.76.253), Proto (6), TTL (64), TOS (0), ... ), CSum (0x1ef5) is ok ] [ Geo (local => Ukraine) ] [ TCP Port (45849 => 443 (https)), SN (0x1744209), AN (0x46ca9611), DataOff (8) ...
