Subject: [stable 4.19][PATCH 02/17] crypto: stm31/hash - Fix hmac issue more than 256 bytes
Date: Thu, 28 Nov 2019 09:49:47 -0700	[thread overview]
Message-ID: <20191128165002.6234-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20191128165002.6234-1-mathieu.poirier@linaro.org>

From: Lionel Debieve <lionel.debieve@st.com>

commit 0acabecebc912b3ba06289e4ef40476acc499a37 upstream

Correct condition for the second hmac loop. Key must be only
set in the first loop. Initial condition was wrong,
HMAC_KEY flag was not properly checked.
