Hello: This patch was applied to netdev/net.git (main) by Jakub Kicinski [off-list ref]: On Fri, 31 May 2024 12:37:11 +0200 you wrote:
When vmxnet3_rq_create() fails to allocate memory for rq->data_ring.base, the subsequent call to vmxnet3_rq_destroy_all_rxdataring does not reset rq->data_ring.desc_size for the data ring that failed, which presumably causes the hypervisor to reference it on packet reception. To fix this bug, rq->data_ring.desc_size needs to be set to 0 to tell the hypervisor to disable this feature. [...]
