patch 'net/cnxk: fix telemetry SA info parameter parsing' 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/147d8242988715364626a75712f8e07247ea551d

Thanks.

Kevin

Subject: [PATCH] net/cnxk: fix telemetry SA info parameter parsing

[ upstream commit 1279ce962b03dcb50782bca3fea314c68867b2ec ]

The /cnxk/ipsec/sa_info handler would silently wrap 32 bit value
to 16 bit port id.
An out-of-range port such as 65536 narrowed to a valid port
for the check and then read past the array.
Reject port ids >= RTE_MAX_ETHPORTS before the lookup.

The /cnxk/ipsec/info handler has similar issue with
strtoul().

Rework parse_params() to walk the string with strtoul()/endptr
rather than strtok(), which is not thread safe and races when the
telemetry callbacks run on per-connection threads. This drops the
strdup()/free(), range checks each value against UINT32_MAX, and
passes an unsigned char to isdigit().

Fixes: d74ed1628f7e ("net/cnxk: add SA info telemetry")
