From 357b6cc5834eabc1be7c28a9faae7da061df097d Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Wed, 18 Mar 2020 10:33:22 +0100 Subject: netfilter: revert introduction of egress hook This reverts the following commits: 8537f78647c0 ("netfilter: Introduce egress hook") 5418d3881e1f ("netfilter: Generalize ingress hook") b030f194aed2 ("netfilter: Rename ingress hook include file") >From the discussion in [0], the author's main motivation to add a hook in fast path is for an out of tree kernel module, which is a red flag to begin with. Other mentioned potential use cases like NAT{64,46} is on future extensions w/o concrete code in the tree yet. Revert as suggested [1] given the weak justification to add more hooks to critical fast-path.
