From f569525911d3dce024ff2b1908e16a20e9052338 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 21 May 2015 15:11:05 +0800 Subject: [PATCH] crypto: aead - Add crypto_aead_maxauthsize This patch adds the helper crypto_aead_maxauthsize to remove the need to directly dereference aead_alg internals by AEAD implementors.
