From da349fad8045cc44cd9b1752b0e2d943df62cabf Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Mon, 19 Feb 2018 11:50:54 +0300 Subject: [PATCH] net: Convert iptable_filter_net_ops These pernet_operations register and unregister net::ipv4.iptable_filter table. Since there are no packets in-flight at the time of exit method is working, iptables rules should not be touched. Also, pernet_operations should not send ipv4 packets each other. So, it's safe to mark them async. Signed-off-by: Kirill Tkhai Signed-off-by: David S.
