Conntrack hashtables are per-netns. They are, but the metadata is not. Sorry for not being clear, but my previous mail was. i.e. there is a per-netns hashtable that is indexed using a global that might change at any time underneath. The htable size and max should be per-netns too. An existing sysctl/module parameter affects these and should also ultimately either iterate through namespaces, or only affect the global init_net (as it almost does now, except it changes the data used by the others and doesn't resize them).
