Subject: [PATCH AUTOSEL 5.3 29/99] selftests/bpf: Set rp_filter in test_flow_dissector
Date: Sat, 26 Oct 2019 09:14:50 -0400 [thread overview]
Message-ID: <20191026131600.2507-29-sashal@kernel.org> (raw)
In-Reply-To: <20191026131600.2507-1-sashal@kernel.org>
From: Jiri Benc <jbenc@redhat.com>
[ Upstream commit fd418b01fe26c2430b1091675cceb3ab2b52e1e0 ]
Many distributions enable rp_filter. However, the flow dissector test
generates packets that have 1.1.1.1 set as (inner) source address without
this address being reachable. This causes the selftest to fail.
The selftests should not assume a particular initial configuration. Switch
off rp_filter.
Fixes: 50b3ed57dee9 ("selftests/bpf: test bpf flow dissection")
