Subject: [PATCH 4.15 23/23] crypto: tcrypt - fix S/G table for test_aead_speed()
Date: Fri, 9 Feb 2018 14:40:21 +0100 [thread overview]
Message-ID: <20180209133939.450994203@linuxfoundation.org> (raw)
In-Reply-To: <20180209133938.366024920@linuxfoundation.org>
4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Baronescu <robert.baronescu@nxp.com>
commit 5c6ac1d4f8fbdbed65dbeb8cf149d736409d16a1 upstream.
In case buffer length is a multiple of PAGE_SIZE,
the S/G table is incorrectly generated.
Fix this by handling buflen = k * PAGE_SIZE separately.
