            Bug ID: 384
           Summary: netvsc PMD crashes in secondary process in
                    dev_info_get
           Product: DPDK
           Version: 19.08
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

Call rte_ethdev_dev_info_get in a secondary process will crash with netvsc =
PMD.

The data structure mapping for the vmbus is not mapped at same address.
It is crashing here because hv->vmbus is not the correct in secondary.

static void *hn_rndis_alloc(struct hn_data *hv, size_t size)
{
        return rte_zmalloc_socket("RNDIS", size, PAGE_SIZE,
                                 hv->vmbus->device.numa_node);
}

The numa_node is not needed for control messages.
But fixing that just exposes the next crash when sending the control messag=
e.
