Subject: [bpf-next PATCH v2 1/5] bpf: sk_msg add some generic helpers that may be useful from sk_msg
Date: Fri, 15 May 2020 15:05:57 -0700 [thread overview]
Message-ID: <158958035716.12532.11872908481088096292.stgit@john-Precision-5820-Tower> (raw)
In-Reply-To: <158958022865.12532.5430684453474460041.stgit@john-Precision-5820-Tower>
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
