Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/c53d6a82e210b02556ac2c6b25d5b054e7f448e0

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix context DMA array allocation size

[ upstream commit 4416758ae996f04b9ab950f5c8b8f3eec21c4df6 ]

ctx_dma_arr stores rte_iova_t entries, but the allocation size was
calculated using sizeof(rte_iova_t *) instead of sizeof(rte_iova_t).

Use the correct element size when allocating the array to match the
actual data type stored in ctx_dma_arr.

Fixes: 4371b402c7bd ("net/bnxt: fix array overflow")
