bpf, sk_msg: Add some generic helpers that may be useful from sk_msg
Add these generic helpers that may be useful to use from sk_msg programs. The helpers do not depend on ctx so we can simply add them here, BPF_FUNC_perf_event_output BPF_FUNC_get_current_uid_gid BPF_FUNC_get_current_pid_tgid BPF_FUNC_get_current_cgroup_id BPF_FUNC_get_current_ancestor_cgroup_id BPF_FUNC_get_cgroup_classid Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/bpf/159033903373.12355.15489763099696629346.stgit@john-Precision-5820-Tower Signed-off-by: Alexei Starovoitov <ast@kernel.org>
