Software event output is only enabled by a few prog types right now (TC, LWT out, XDP, sockops). Many other skb based prog types need bpf_skb_event_output to produce software event. More prog types are enabled to access bpf_skb_event_output in this patch. v2 changes: Reformating log message. v3 changes: Reformating log message. v4 changes: Reformating log message. v5 changes: Fix typos, reformat comments in event_output.c, move revision history to cover letter. v6 changes: fix Signed-off-by, fix fixup map creation. 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 | 12 ++- .../selftests/bpf/verifier/event_output.c | 94 +++++++++++++++++++ 3 files changed, 111 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/bpf/verifier/event_output.c -- 2.22.0.410.gd8fdbe21b5-goog
