Subject: [PATCH bpf-next v4 2/3] selftests/bpf: Add connmark read test
Date: Thu, 11 Aug 2022 15:55:26 -0600 [thread overview]
Message-ID: <d3bc620a491e4c626c20d80631063922cbe13e2b.1660254747.git.dxu@dxuuu.xyz> (raw)
In-Reply-To: <cover.1660254747.git.dxu@dxuuu.xyz>
Test that the prog can read from the connection mark. This test is nice
because it ensures progs can interact with netfilter subsystem
correctly.
Signed-off-by: Daniel Xu <dxu@dxuuu.xyz>
