While going through the cgroup namespace I found a couple of significant
bugs. The first bug I fix could cause a kernel deadlock. The second
fixes a rare race that if it happens we get insane semantics. The third
removes an allowance that could not possibly be used.
The patches have been respun against for-v4.7-fixes
Eric W. Biederman (3):
cgroupns: Fix the locking in copy_cgroup_ns
cgroupns: Close race between cgroup_post_fork and copy_cgroup_ns
cgroupns: Only allow creation of hierarchies in the initial cgroup namespace
