[PATCH bpf v2 2/5] selftests/bpf: test_sockmap, join cgroup in selftest mode
From: Prashant Bhole <hidden>
Date: 2018-05-28 04:39:30
Also in:
linux-kselftest
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, Shuah Khan, Shuah Khan, Linus Torvalds
In case of selftest mode, temporary cgroup environment is created but
cgroup is not joined. It causes test failures. Fixed by joining the
cgroup
