2016-04-25	trafgen: proto: Add ICMPv6 header generation	Tobias Klauser	1	-0/+6
	Support for generating simple ICMPv6 headers using the 'icmp6()/icmpv6()' trafgen generation function. Fields supported: mtype Message type (default: 0) Supported keywords: echorequest, echoreply code Code (default: 0) csum Message checksum (calculated by default) Examples: { eth(), ipv6(daddr=::1), icmpv6(echorequest), 42, 42, 0, 0 }' If not explicitely specified, the lower header is initialized as Ethernet.

2016-02-01	trafgen: parser: Add TCP header generation function	Tobias Klauser	1	-0/+19
	Add a function 'tcp()' to generate TCP headers from the trafgen configuration language. Fields supported: sp\|sport TCP source port (default 0) dp\|dport TCP destination port (default 0) seq Sequence number (default: 0) aseq\|ackseq Acknowledgement number (default 0) doff\|hlen Header length/data offset (default: 5) cwr Congestion Window Reduced flag (default: 0) ece\|ecn ECN-Echo flag (default: 0) urg Urgent flag (default: 0) ack Acknowledgement flag (default: 0) psh Push flag (default: 0) rst Reset flag (default: 0) syn Synchronize flag (default: 0) fin Finish flag (default: 0) win\|window Receive window size (default: 0) csum Checksum field (calculated automatically) urgptr Urgent pointer (default: 0) Example (SYN on port 80/http): { tcp(dport=80, syn, window=5840) } Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-01-29	trafgen: l4: Add UDP header generation logic	Vadim Kochan	1	-0/+13
	Add trafgen_l4.c module with generation UDP header fields. UDP protocol generation logic automaticaly sets the protocol field of the lower level protocol to IPPROTO_UDP by default (if it is IPv4). Also checksum & length are calculated and set if it is not given by the user. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
