During network namespace stop process kernel side netlink sockets belonging to a namespace should be closed. They should not prevent namespace to stop, so they do not increment namespace usage counter. Though this counter will be put during last sock_put. The raplacement of the correct netns for init_ns solves the problem only partial as socket to be stoped until proper stop is a valid netlink kernel socket and can be looked up by the user processes. This is not a problem until it resides in initial namespace (no processes inside this net), but this is not true for init_net. So, hold the referrence for a socket, remove it from lookup tables and only after that change namespace and perform a last put. Signed-off-by: Denis V.
