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 07/05/26. 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/f99a95a6e3c8d9c0a652b5d996d333190f2af3fe

Thanks.

Luca Boccassi

Subject: [PATCH] event/cnxk: fix static analysis issues

[ upstream commit 8ae2104936d9bc9212ead3be4797d2cffe539e8a ]

Cast uint16_t operands to uint64_t before bitwise OR with
uint64_t rx_offloads to fix operand size mismatches. Add NULL
check for bracket parser end pointer to prevent undefined
behavior from pointer comparison with NULL.

Fixes: 697883bcb0a8 ("event/cnxk: fix Rx timestamp handling")
Fixes: fe7ed2ebbf37 ("event/cnxk: set Rx offload flags")
Fixes: 38c2e3240ba8 ("event/cnxk: add option to control SSO HWGRP QoS")
Fixes: 8a3d58c189fd ("event/cnxk: add option to control timer adapters")
