What about making this sysctl per-netns? That way a bridge running inside a netns could disable iptables processing, it seems to be global switch at this time. This way you could not enable iptables processing on a bridge without defrag enabled (again, if the module is loaded), OTOH I don't see why one would want iptables on a bridge without conntrack (might as well just use ebtables). -- 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
