Title
gve: fix XSK buffer leak when rings are stopped
Summary
In the Linux kernel, the following vulnerability has been resolved: gve: fix XSK buffer leak when rings are stopped GVE does not free XSK buffers when resetting ring state as a part of stopping queues. This causes all XSK buffers which are posted to the NIC to be leaked. Free XSK buffers attached to an allocated buf_state when stopping rings. This issue was hit in production.
