> Alexey Dobriyan found, that virtualized netlink kernel sockets (fibl &
> rtnl) are leaked during namespace start/stop loop.
> Leaking fix (simple and obvious) reveals that netlink kernel socket
> disposal leads to OOPSes:
> - nl_table[protocol]->listeners is double freed
> - sometimes during namespace stop netlink_sock_destruct
> BUG_TRAP(!atomic_read(&sk->sk_rmem_alloc)); is hit
> This set address all these issues.
