From 4c82fd0abb87e20d0d68ef5237e74732352806c8 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Wed, 20 Dec 2017 12:08:33 +0100 Subject: [PATCH] netfilter: uapi: correct UNTRACKED conntrack state bit number nft_ct exposes this bit to userspace. This used to be #define NF_CT_STATE_UNTRACKED_BIT (1 << (IP_CT_NUMBER + 1)) (IP_CT_NUMBER is 5, so this was 0x40) .. but this got changed to 8 (0x100) when the untracked object got removed. Replace this with a literal 6 to prevent further incompatible changes in case IP_CT_NUMBER ever increases.
