bpf: Fix bpf_xdp_event_output
Fix a typo. xdp->data instead of xdp should be copied to the perf-event's dst_buff. Fixes: 4de16969523c ("bpf: enable event output helper also for xdp types") Reported-by: Huapeng Zhou <[email protected]> Tested-by: Feixiong Zhang <[email protected]> Acked-by: Alexei Starovoitov <[email protected]> Cc: Daniel Borkmann <[email protected]> Signed-off-by: Martin KaFai Lau <[email protected]> Acked-by: Daniel Borkmann <[email protected]> Signed-off-by: David S.
