Subject: [PATCH AUTOSEL 5.3 30/99] selftests/bpf: More compatible nc options in test_lwt_ip_encap
Date: Sat, 26 Oct 2019 09:14:51 -0400 [thread overview]
Message-ID: <20191026131600.2507-30-sashal@kernel.org> (raw)
In-Reply-To: <20191026131600.2507-1-sashal@kernel.org>
From: Jiri Benc <jbenc@redhat.com>
[ Upstream commit 106c35dda32f8b63f88cad7433f1b8bb0056958a ]
Out of the three nc implementations widely in use, at least two (BSD netcat
and nmap-ncat) do not support -l combined with -s. Modify the nc invocation
to be accepted by all of them.
Fixes: 17a90a788473 ("selftests/bpf: test that GSO works in lwt_ip_encap")
