patch 'net/gve: clear out shared memory region for statistics' 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 08/04/26. 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/43578d49f489015109ab97d1f011499c8f042435

Thanks.

Kevin

Subject: [PATCH] net/gve: clear out shared memory region for statistics

[ upstream commit 316cfac2c0c23d5a54996d8a9a5392c4e4b9c8bb ]

The stats report memzone is allocated from hugepage memory which could
possibly have had sensitive data from a previous DPDK invocation.

Clear out the buffer before sharing the memory region with the virtual
device to protect guest memory.

Fixes: 458b53dec01e ("net/gve: enable imissed stats for GQ format")
