selftests/bpf: remove useless bpf_trace_printk

2017-11-01T03:06:46Z

sockmap test is using two programs that use bpf_trace_printk() which prints into trace_pipe, but nothing is reading it. Remove it. Fixes: 6f6d33f3b3d0 ("bpf: selftests add sockmap tests") Signed-off-by: Alexei Starovoitov Signed-off-by: David S. Miller

bpf: additional sockmap self tests

2017-08-28T18:13:21Z

Add some more sockmap tests to cover, - forwarding to NULL entries - more than two maps to test list ops - forwarding to different map Signed-off-by: John Fastabend Acked-by: Alexei Starovoitov Signed-off-by: David S. Miller

bpf: convert sockmap field attach_bpf_fd2 to type

2017-08-28T18:13:21Z

In the initial sockmap API we provided strparser and verdict programs using a single attach command by extending the attach API with a the attach_bpf_fd2 field. However, if we add other programs in the future we will be adding a field for every new possible type, attach_bpf_fd(3,4,..). This seems a bit clumsy for an API. So lets push the programs using two new type fields. BPF_SK_SKB_STREAM_PARSER BPF_SK_SKB_STREAM_VERDICT This has the advantage of having a readable name and can easily be extended in the future. Updates to samples and sockmap included here also generalize tests slightly to support upcoming patch for multiple map support.

bpf: selftests add sockmap tests

2017-08-16T18:27:53Z

This generates a set of sockets, attaches BPF programs, and sends some simple traffic using basic send/recv pattern. Additionally, we do a bunch of negative tests to ensure adding/removing socks out of the sockmap fail correctly. Signed-off-by: John Fastabend Signed-off-by: David S. Miller
