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_comm BPF_FUNC_get_current_cgroup_id BPF_FUNC_get_current_ancestor_cgroup_id BPF_FUNC_get_cgroup_classid Acked-by: Yonghong Song <yhs@xxxxxx> Signed-off-by: John Fastabend <john.fastabend@xxxxxxxxx> --- net/core/filter.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/net/core/filter.c b/net/core/filter.c index 822d662..a56046a 100644 --- a/net/core/filter.c +++ b/net/core/filter.c @@ -6443,6 +6443,22 @@ sk_msg_func_proto(enum bpf_func_id func_id, const struct bpf_prog *prog) return &bpf_msg_push_data_proto; case BPF_FUNC_msg_pop_data: return &bpf_msg_pop_data_proto; + case BPF_FUNC_perf_event_output: + return &bpf_event_output_data_proto; + case BPF_FUNC_get_current_uid_gid: + return &bpf_get_current_uid_gid_proto; + case BPF_FUNC_get_current_pid_tgid: + return &bpf_get_current_pid_tgid_proto; +#ifdef CONFIG_CGROUPS + case BPF_FUNC_get_current_cgroup_id: + return &bpf_get_current_cgroup_id_proto; + case BPF_FUNC_get_current_ancestor_cgroup_id: + return &bpf_get_current_ancestor_cgroup_id_proto; +#endif +#ifdef CONFIG_CGROUP_NET_CLASSID + case BPF_FUNC_get_cgroup_classid: + return &bpf_get_cgroup_classid_curr_proto; +#endif default: return bpf_base_func_proto(func_id); }
