- Explicitly limit exit task stat broadcast to the initial user and pid namespaces, as it is already limited to the initial network namespace. - For broadcast task stats explicitly generate all of the idenitiers in terms of the initial user namespace and the initial pid namespace. - For request stats report them in terms of the current user namespace and the current pid namespace. Netlink messages are delivered syncrhonously to the kernel allowing us to get the user namespace and the pid namespace from the current task. - Pass the namespaces for representing pids and uids and gids into bacct_add_task.
