patch 'eventdev/timer: reject out-of-range telemetry ID' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/01/26. 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/468fe6248eaf32f7225ce13d02ce8de26c4ebb58

Thanks.

Kevin

Subject: [PATCH] eventdev/timer: reject out-of-range telemetry ID

[ upstream commit bd841c3e2533493fa91e8ba9cf33c637629e4d1d ]

The eventdev timer adapter code was using atoi() to parse numeric
parameters which does not handle out-of-range or extra garbage
on input. Tighten the code to only accept valid numbers.

Fixes: 791dfec24d00 ("eventdev/timer: add telemetry")
