Hi, I wonder, it it makes sense to backport commit e666d4e9ceec crypto: vmx - Use skcipher for ctr fallback to v 4.14 stable kernel. I'm using it in 4.12+. These commits (somehow similar) has been backported to 4.10.2: 5839f555fa57 crypto: vmx - Use skcipher for xts fallback c96d0a1c47ab crypto: vmx - Use skcipher for cbc fallback Kind regards, Petr
