Many other skb based prog types need bpf_skb_event_output to produce software event. Added socket_filter, cg_skb, sk_skb prog types to generate sw event. *** BLURB HERE *** allanzhang (2): bpf: Allow bpf_skb_event_output for a few prog types bpf: Add selftests for bpf_perf_event_output net/core/filter.c | 6 ++ tools/testing/selftests/bpf/test_verifier.c | 33 ++++++- .../selftests/bpf/verifier/event_output.c | 94 +++++++++++++++++++ 3 files changed, 132 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/bpf/verifier/event_output.c -- 2.22.0.410.gd8fdbe21b5-goog
