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/1cbfce2bfd3d1ceb3c44ed7455f2b2a5fea4f446

Thanks.

Luca Boccassi

Subject: [PATCH] eventdev: improve bounds checks for names in adapter create

[ upstream commit 5dc372bcb5d6aa7c4ac47d11e0d2dfc2a5c4468b ]

The bounds checks for snprintf and then strncpy used different constant
defines, which happened to resolve to the same value (32). Make this
code more resilient by using sizeof() operator rather than the defines,
and replace use of strncpy with the better strlcpy.

Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")
