Subject: [PATCH v2 12/12] crypto: hisilicon/zip - Use temporary sqe when doing work
Date: Sat, 9 May 2020 17:44:05 +0800 [thread overview]
Message-ID: <1589017445-15514-13-git-send-email-tanshukun1@huawei.com> (raw)
In-Reply-To: <1589017445-15514-1-git-send-email-tanshukun1@huawei.com>
From: Zhou Wang <wangzhou1@hisilicon.com>
Currently zip sqe is stored in hisi_zip_qp_ctx, which will bring corruption
with multiple parallel users of the crypto tfm.
This patch removes the zip_sqe in hisi_zip_qp_ctx and uses a temporary sqe
instead.
