2015-08-17	selftests/net: test classic bpf fanout mode	Willem de Bruijn	1	-8/+21
	Test PACKET_FANOUT_CBPF by inserting a cBPF program that selects a socket by payload. Requires modifying the test program to send packets with multiple payloads. Also fix a bug in testing the return value of mmap() Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-07	selftests: net: add PF_PACKET TPACKET v1/v2/v3 selftests	Daniel Borkmann	1	-0/+127
	This patch adds a simple test case that probes the packet socket's TPACKET_V1, TPACKET_V2 and TPACKET_V3 behavior regarding mmap(2)'ed I/O for a small burst of 100 packets. The test currently runs for ... TPACKET_V1: RX_RING, TX_RING TPACKET_V2: RX_RING, TX_RING TPACKET_V3: RX_RING ... and will output on success: test: TPACKET_V1 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V1 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V3 with PACKET_RX_RING .................... 100 pkts (9600 bytes) OK. All tests passed Reusable parts of psock_fanout.c have been put into a psock_lib.h file for common usage. Test case successfully tested on x86_64.
