Subject: [PATCH 4.19 43/52] crypto: atmel-sha - fix error handling when setting hmac key
Date: Thu, 13 Feb 2020 07:21:24 -0800 [thread overview]
Message-ID: <20200213151827.802990585@linuxfoundation.org> (raw)
In-Reply-To: <20200213151810.331796857@linuxfoundation.org>
From: Eric Biggers <ebiggers@google.com>
commit b529f1983b2dcc46354f311feda92e07b6e9e2da upstream.
HMAC keys can be of any length, and atmel_sha_hmac_key_set() can only
fail due to -ENOMEM. But atmel_sha_hmac_setkey() incorrectly treated
any error as a "bad key length" error. Fix it to correctly propagate
the -ENOMEM error code and not set any tfm result flags.
Fixes: 81d8750b2b59 ("crypto: atmel-sha - add support to hmac(shaX)")
