2017-07-17trafgen: Delegate creation of rfraw to dev_io APIVadim Kochan1-1/+2
Simplify a bit of creation rfraw device by delegating it to the dev_io API, also in case the output device is pcap file the --rfraw option sets the link type to ieee80211 radio tap. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2017-06-09trafgen: Allow to generate packets to output pcap fileVadim Kochan1-2/+3
Add trafgen_dev.c module which provides generic way of reading and writing packets to/from networking device or a pcap file. Also allow to handle output pcap file via '-o, --out, --dev' option. It might be useful in future for testing some link protocols which is not easy to capture (e.g. wlan packets) w/o having some special setup.

2014-08-21trafgen: add option to not adjust system socket mem during testrunJesper Dangaard Brouer1-0/+9
The default behavior of trafgen is to boost the systems default socket memory limits during a testrun. This behaviour does not always result in improved performance, because this will stress the kernels SLAB allocators unnecessary. Introducing an option "--no-sock-mem" that instruct trafgen to not perform any socket memory adjustments.

The -k/--kernel-pull option got useless with commit c139e80 ("trafgen: remove timer-based trigger model").

2013-12-12trafgen: take advantage of PACKET_QDISC_BYPASS sock optionJesper Dangaard Brouer1-0/+6
Since Linux 3.14, the kernel supports a socket option PACKET_QDISC_BYPASS, which trafgen enables by default. That allow us to bypass the kernels normal qdisc (traffic control) layer. An option -q, --qdisc-path is added to allow enabling the qdisc path explicity, useful for testing purposes. This will be avail in kernels >= 3.14 via commit d346a3fae3 (packet: introduce PACKET_QDISC_BYPASS socket option). Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com>

2013-06-15trafgen: fix checksumming in trafgen example configDaniel Borkmann1-1/+1
Took quite a while to git bisect the cause for the wrong TCP checksum in the -e example. It turned out that commit bf43e1993c7037 ("trafgen: lexer: return original string if no shellcode") "broke" it, since before that commit the TCP checksum from -e example was correct and afterwards not anymore. Well, it didn't break it. What was happening here is that with this fix above, the packet got 1 byte longer since the first character of the example string is not omitted anymore, therefore the checksum got wrong. Fix this by fixing the IP total length of the packet in the -e and man page example. The UDP example from the man page still works well if csumudp() is used, so not affected of this.
