patch 'crypto/openssl: fix warning on copy length' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=24dc362291a26d0450a72193a4e06839bb743bdc

Thanks.

[ upstream commit f481e9272a2f7c980519eac773acf0a9af23ea34 ]

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]

Fixed the warning by copying up to string / buffer size.

Fixes: 75adf1eae44f ("crypto/openssl: update HMAC routine with 3.0 EVP API")
