Subject: Re: [PATCH] crypto: Make CRYPTO_CBC select CRYPTO_ECHAINIV
Date: Mon, 4 Jan 2016 21:43:53 +0100	[thread overview]
Message-ID: <568AD989.8060802@gmx.de> (raw)
In-Reply-To: <4445865.9O5pIU29W2@myon.chronox.de>

Similar to CTR mode selecting CRYPTO_SEQIV, CBC mode requires echainiv
and has to select CRYPTO_ECHAINIV in order to work properly. This solves
the issues caused by a misconfiguration as described in [1].
