Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/f47561c93d79ea0b7f6823c9782947c67e152720

Thanks.

Luca Boccassi

Subject: [PATCH] common/cnxk: replace strncpy with strlcpy

[ upstream commit 95e9d9bc258dffdd5920002b9b7590868c7bda7d ]

Replace strncpy() with safer strlcpy() which always null-terminates.

Fixes: 014a9e222bac ("common/cnxk: add model init and IO handling API")
Fixes: b315581c66dc ("common/cnxk: skip probing SoC environment for CN9K")
