Subject: netfilter: uapi: correct UNTRACKED conntrack state bit number
From: Florian Westphal <fw@strlen.de>
[ Upstream commit 4c82fd0abb87e20d0d68ef5237e74732352806c8 ]
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.
Fixes: cc41c84b7e7f2 ("netfilter: kill the fake untracked conntrack objects")
