2018-03-19	bpf: add map tests for BPF_PROG_TYPE_SK_MSG	John Fastabend	1	-2/+13
	Add map tests to attach BPF_PROG_TYPE_SK_MSG types to a sockmap. Signed-off-by: John Fastabend <john.fastabend@gmail.com> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2017-11-01	selftests/bpf: remove useless bpf_trace_printk	Alexei Starovoitov	1	-3/+0
	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 <ast@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-28	bpf: additional sockmap self tests	John Fastabend	1	-3/+3
	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 <john.fastabend@gmail.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-28	bpf: convert sockmap field attach_bpf_fd2 to type	John Fastabend	1	-1/+1
	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.

2017-08-16	bpf: selftests add sockmap tests	John Fastabend	1	-0/+38
	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 <john.fastabend@gmail.com> Signed-off-by: David S.
