Subject: [PATCH bpf-next v4 0/2] bpf: Allow bpf_skb_event_output for more prog types

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.

Added socket_filter, cg_skb, sk_skb prog types to generate sw event.

allanzhang (2):
  bpf: Allow bpf_skb_event_output for a few prog types
  bpf: Add selftests for bpf_perf_event_output
