Subject: [PATCH bpf-next v4 2/5] selftests/bpf: test_sockmap, join cgroup in selftest mode
Date: Thu, 31 May 2018 13:42:37 +0900	[thread overview]
Message-ID: <20180531044240.796-3-bhole_prashant_q7@lab.ntt.co.jp> (raw)
Message-ID: <20180531044237.3iDDQVMhCWi1nMjcH2m0F5swANimunySSr6hFAn2V1w@z> (raw)
In-Reply-To: <20180531044240.796-1-bhole_prashant_q7@lab.ntt.co.jp>

In case of selftest mode, temporary cgroup environment is created but
cgroup is not joined. It causes test failures. Fixed by joining the
cgroup

Fixes: 16962b2404ac ("bpf: sockmap, add selftests")
