Subject: [dpdk-stable] [PATCH] crypto/qat: fix segmentation fault in session create
Date: Fri, 12 May 2017 16:41:34 +0100 [thread overview]
Message-ID: <1494603694-5389-2-git-send-email-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <1494603694-5389-1-git-send-email-arkadiuszx.kusztal@intel.com>
From: Arkadiusz Kusztal <arkadiuszx.kusztal@intel.com>
This patch fixes segementation fault that may occur in case
of wrong parameters being provided to the cryptographic
session. Unused fields which would cause null dereference
are removed.
Fixes: 1703e94ac5ce ("qat: add driver for QuickAssist devices")
