I am in favor of the user namespace tie in. I am in favor of running a per user namespace audit filter once per user namespace walking up the user namespace hierarchy. Each filter would deliver messages to a different userspace audit daemon. Until we agreement to go that far I am not certain the kernel generated audit messages should go anywhere except to the global audit daemon. I think on an individual basis we can look at kernel audit messages and see if they should go to just the global user namespace. Just the user namspace of the relevant network stack. Or if the message should go to the audit daemon of every user namespace that is an ancestor of some starting user namespace. But please let's error on the side of caution here.
