Subject: [PATCH] arm/arm64/crypto: assure that ECB modes don't require an IV
Date: Fri, 12 Feb 2016 09:47:52 -0600 [thread overview]
Message-ID: <1455292072-5236-1-git-send-email-jeremy.linton@arm.com> (raw)
ECB modes don't use an initialization vector. The kernel
/proc/crypto interface doesn't reflect this properly.
