Subject: [PATCH v3 1/3] lib/cryptodev: avoid implicit conversion to 64 bit number
Date: Mon, 27 Jan 2025 11:33:07 -0800 [thread overview]
Message-ID: <1738006389-17193-1-git-send-email-andremue@linux.microsoft.com> (raw)
In-Reply-To: <1732758837-6350-1-git-send-email-andremue@linux.microsoft.com>
MSVC issues the warning below:
../lib/cryptodev/rte_cryptodev.c(623): warning C4334: '<<':
result of 32-bit shift implicitly converted to 64 bits
(was 64-bit shift intended?)
The code would be better off by using 64 bit numbers to begin with.
That eliminates the need for a conversion to 64 bits later.
This patch actually fixes a bug present in previous DPDK versions
because the last of the hash enums RTE_CRYPTO_AUTH_SM3_HMAC in
rte_crypto_auth_algorithm has value 32.
Fixes: 6f8ef8b68edb ("cryptodev: add hash algorithms in asymmetric capability")
