Subject: [PATCH bpf-next v3 09/12] selftests: bpf: don't listen() on UDP sockets
Date: Wed,  4 Mar 2020 11:13:14 +0100	[thread overview]
Message-ID: <20200304101318.5225-10-lmb@cloudflare.com> (raw)
In-Reply-To: <20200304101318.5225-1-lmb@cloudflare.com>

Most tests for TCP sockmap can be adapted to UDP sockmap if the
listen call is skipped. Rename listen_loopback, etc. to socket_loopback
and skip listen() for SOCK_DGRAM.
