It follows /proc/net/xt_{hashlimit,recent}/. I'm starting to like this more and more too, as my code is getting much smaller ;) One quick question, though. Do you have any ideas on how I can make sure that the user doesn't supply the same name twice (ie. two rules with the same user_supplied_name)? The problem is that the userspace always re-adds all the existing rules before inserting a new one and only later deletes the old rules. :\ -- Cheers, Luca.
