Subject: netfilter: uapi: correct UNTRACKED conntrack state bit number
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8a5c84b1055a1882992de51f1b2bb5b0989cbbf6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

netfilter: uapi: correct UNTRACKED conntrack state bit number


[ 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")
