2019-10-17	selftests/bpf: Add kfree_skb raw_tp test	Alexei Starovoitov	1	-0/+89
	Load basic cls_bpf program. Load raw_tracepoint program and attach to kfree_skb raw tracepoint. Trigger cls_bpf via prog_test_run. At the end of test_run kernel will call kfree_skb which will trigger trace_kfree_skb tracepoint. Which will call our raw_tracepoint program. Which will take that skb and will dump it into perf ring buffer. Check that user space received correct packet.
