From 1cd472bf036ca038e783ef5f058f54e45b7e8180 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 14 May 2018 23:46:57 +0200 Subject: netfilter: nf_nat: add nat hook register functions to nf_nat This adds the infrastructure to register nat hooks with the nat core instead of the netfilter core. nat hooks are used to configure nat bindings. Such hooks are registered from ip(6)table_nat or by the nftables core when a nat chain is added. After next patch, nat hooks will be registered with nf_nat instead of netfilter core. This allows to use many nat lookup functions at the same time while doing the real packet rewrite (nat transformation) in one place. This change doesn't convert the intended users yet to ease review.
