Subject: extensions: cluster: Avoid undefined shift
X-Git-Tag: v1.8.5~78
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=28c16371cdad16707674450b59919e3d97185694;p=thirdparty%2Fiptables.git

extensions: cluster: Avoid undefined shift

Value 1 is signed by default and left-shifting by 31 is undefined for
those. Fix this by marking the value as unsigned.

Fixes: 64a0e09894e52 ("extensions: libxt_cluster: Add translation to nft")
