Ok, can I get one more clarification on this "hierarchy"? Is it roughly in the order they appear in nf_tables_commit() after step 3? It appears it might be mostly already. If it isn't already, would it be reasonable to re-order them? Would you suggest a different order?

Would the generation change id be useful outside the kernel? What exactly does it look like? I don't quite understand the genmask purpose. - RGB -- Richard Guy Briggs <rgb@xxxxxxxxxx> Sr. S/W Engineer, Kernel Security, Base Operating Systems Remote, Ottawa, Red Hat Canada IRC: rgb, SunRaycer Voice: +1.647.777.2635, Internal: (81) 32635
