patch 'examples/fips_validation: fix RSA memcpy' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/529424fc6dfb22e2352345aca9e965e906948ecd

Thanks.

Kevin

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit dac0edb433859c026b35615495b48dc6d394b7b8 ]

The code for copying example hash key values was calling rte_memcpy
but rte_memcpy is generating vector instruction that references
past the array.

In function ‘get_hash_oid’,
    inlined from ‘prepare_rsa_xform’
        at ../examples/fips_validation/main.c:1607:12:
examples/fips_validation/main.c:890:20:
    warning: array subscript ‘__m128i_u[0]’
    is partly outside array bounds of ‘uint8_t[15]’
    {aka ‘unsigned char[15]’} [-Warray-bounds=]
  890 |                 id = id_sha1;
      |                 ~~~^~~~~~~~~
In function ‘prepare_rsa_xform’:
examples/fips_validation/main.c:882:17: note: object ‘id_sha1’ of size 15
  882 |         uint8_t id_sha1[] = {0x30, 0x21, 0x30, 0x09, 0x06, 0x05,

Workaround is to replace rte_memcpy with memcpy.
