a ref is taken on the 'struct sock' in the mq_notify() syscall and the skbuff which will be send to notify the user is also allocated in the mq_notify() syscall. So we should be in the same net namespace when we register the notification and when we notify. I hope the net guys can confirm or we will easily check in the next -lxc patchset which will merge this patchset with netns. however, we have an issue with the signal notification in __do_notify() we could kill a process in a different pid namespace.
