Subject: [PATCH v3 bpf-next 0/4] cgroup bpf auto-detachment
Date: Thu, 23 May 2019 12:45:28 -0700 [thread overview]
Message-ID: <20190523194532.2376233-1-guro@fb.com> (raw)
This patchset implements a cgroup bpf auto-detachment functionality:
bpf programs are detached as soon as possible after removal of the
cgroup, without waiting for the release of all associated resources.
Patches 2 and 3 are required to implement a corresponding kselftest
in patch 4.
v3:
1) some minor changes and typo fixes
v2:
1) removed a bogus check in patch 4
2) moved buf[len] = 0 in patch 2
Roman Gushchin (4):
bpf: decouple the lifetime of cgroup_bpf from cgroup itself
selftests/bpf: convert test_cgrp2_attach2 example into kselftest
selftests/bpf: enable all available cgroup v2 controllers
selftests/bpf: add auto-detach test
