Subject: [PATCH bpf-next 1/4] selftests/bpf: Handle SIGINT when creating netns
Date: Tue, 07 May 2024 12:53:31 +0200 [thread overview]
Message-ID: <20240507-upstream-bpf-next-20240506-mptcp-subflow-test-v1-1-e2bcbdf49857@kernel.org> (raw)
In-Reply-To: <20240507-upstream-bpf-next-20240506-mptcp-subflow-test-v1-0-e2bcbdf49857@kernel.org>
From: Geliang Tang <tanggeliang@kylinos.cn>
It's necessary to delete netns during the MPTCP bpf tests interrupt,
otherwise the next tests run will fail due to unable to create netns.
This patch adds a new SIGINT handle sig_int, and deletes NS_TEST in it.
