Subject: [PATCH v2] crypto/openssl: fix warning on copy length
Date: Mon, 9 Jan 2023 11:40:21 +0800 [thread overview]
Message-ID: <20230109034021.2759215-1-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20230106101520.2736826-1-ruifeng.wang@arm.com>
When building with gcc 11.2.0, the compiler warns as follows:
In function 'memcpy',
inlined from 'openssl_set_session_auth_parameters' at ../drivers/crypto/openssl/rte_openssl_pmd.c:699:3,
inlined from 'openssl_set_session_parameters' at ../drivers/crypto/openssl/rte_openssl_pmd.c:826:9:
/usr/include/aarch64-linux-gnu/bits/string_fortified.h:29:10: warning: '__builtin_memcpy' forming offset [4, 8] is out of the bounds [0, 4] [-Warray-bounds]
Fixed the warning by copying up to string / buffer size.
Fixes: 75adf1eae44f ("crypto/openssl: update HMAC routine with 3.0 EVP API")
