Indeed. Rainer, while your desire to keep CONFIG_NET_NS=n case equivalent to current code is understandable and kernel people share it at large, what you're fighting for is maybe one dereference on speed-uncritical code paths and one pointer in small amount of data structures. As such having common executable code matters more. netns will be stubbed to &init_net at several places. See how e. g. xt_hashlimit is done. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
