From a74d850f787ef9578fa2829bfaecb222269cb754 Mon Sep 17 00:00:00 2001 From: Pascal van Leeuwen Date: Tue, 2 Jul 2019 16:39:56 +0200 Subject: [PATCH] crypto: inside-secure - fix EINVAL error (buf overflow) for AEAD decrypt This patch fixes a buffer overflow error returning -EINVAL for AEAD decrypt operations by NOT appending the (already verified) ICV to the output packet (which is not expected by the API anyway). With this fix, all testmgr AEAD (extra) tests now pass.
