Subject: [PATCH net-next 09/10] tls: rx: use MAX_IV_SIZE for allocations
Date: Mon, 11 Apr 2022 12:19:16 -0700 [thread overview]
Message-ID: <20220411191917.1240155-10-kuba@kernel.org> (raw)
In-Reply-To: <20220411191917.1240155-1-kuba@kernel.org>
IVs are 8 or 16 bytes, no point reading out the exact value
for quantities this small.
