Subject: [PATCH AUTOSEL 4.19 398/671] crypto: inside-secure - fix zeroing of the request in ahash_exit_inv
Date: Thu, 16 Jan 2020 12:00:36 -0500
Message-ID: <20200116170509.12787-135-sashal@kernel.org> (raw)
In-Reply-To: <20200116170509.12787-1-sashal@kernel.org>

From: Antoine Tenart <antoine.tenart@bootlin.com>

[ Upstream commit b926213d6fede9c9427d7c12eaf7d9f0895deb4e ]

A request is zeroed in safexcel_ahash_exit_inv(). This request total
size is EIP197_AHASH_REQ_SIZE while the memset zeroing it uses
sizeof(struct ahash_request), which happens to be less than
EIP197_AHASH_REQ_SIZE. This patch fixes it.
