patch 'net/octeontx/base: fix out-of-bounds DQ range lookup' has been queued to stable release 24.11.7

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/ca7833fb1500930f0dd9c3a7bc52ea36d300bca4

Thanks.

Luca Boccassi

Subject: [PATCH] net/octeontx/base: fix out-of-bounds DQ range lookup

[ upstream commit 24c8dff6b939236319633912539ccfe2dfb03c32 ]

In octeontx_pko_dq_range_lookup(), the inner while loop evaluates the
array access ctl->dq_map[dq].chanid before the bounds check
dq < RTE_DIM(ctl->dq_map). When dq is incremented to 256 inside the
loop, the next iteration reads one element past the end of the
256-element dq_map array before the bounds condition can short-circuit.

Swap the two conjuncts so the bounds check is evaluated first, matching
the pattern already used in the outer loop.

Fixes: cad78ca23818 ("net/octeontx/base: add base PKO operations")
