Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/ca4fcfe8ddbc65de7ba4c4a03bac5a91f68ac8d8

Thanks.

Luca Boccassi

Subject: [PATCH] ethdev: make telemetry parameter parsing thread-safe

[ upstream commit d9b281c9c53767ab33efe86eb54cd1088e16f990 ]

The ethdev telemetry handlers run in a per-connection thread.
Two of the parameter parsers used strtok(), which keeps its state in a
process-global static shared across threads.
Use strtok_r() with a local save pointer.

Also pass an unsigned char to isdigit(),
which is undefined for characters with high-bit set.

Fixes: 9e7533aeb80a ("ethdev: add telemetry command for TM level capabilities")
Fixes: f38f62650f7b ("ethdev: add Rx queue telemetry query")
