From 439af62bca4794d78d53fb4634f560d6a75f0adb Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Sat, 29 Jul 2017 12:46:09 +0300 Subject: trafgen: Dump proto headers in *.cfg format Added trafgen_dump.c module which dumps headers from packet in .cfg format. Packet is dumped if -o .cfg was specified, it might be useful to specify *.pcap file as input and convert it into .cfg file to edit proto fields in human readable format. To make it possible several main changes were added: 1) packet id is embedded into struct packet.id, and it is updated on each realloc_packet() 2) Added new struct proto_hdr.get_next_proto callback to make possible apply fields of next header. 3) Added new dev_io ops for writting packets into .cfg file, to re-use common dev_io mechsnism for packets dumping. Before dump the default ETH_PROTO fields are applied as first header and then next proto_hdr is identified via .get_next_proto(...) callback. Meanwhile only eth, arp, vlan, ip4, udp, & tcp protos can be dissected into *.cfg format.
