Subject: [PATCH bpf-next 3/5] libbpf: Support guessing sendmsg{4,6} progs
Date: Fri, 18 May 2018 19:21:11 -0700 [thread overview]
Message-ID: <3cf66a79bdfd3944c6d09e3aaddfd2eef9358b65.1526694154.git.rdna@fb.com> (raw)
In-Reply-To: <cover.1526694154.git.rdna@fb.com>
libbpf can guess prog type and expected attach type based on section
name. Add hints for "cgroup/sendmsg4" and "cgroup/sendmsg6" section
names.
