Subject: [PATCH] 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")
|
||
|
|
(cherry picked from commit 28c16371cdad16707674450b59919e3d97185694)
