Hi,
Would you please provide a list of impacted APIs, thus we can check if our code has further issues. b.t.w, we are now using dpdk 18.11. Thanks. 2019年8月14日 下午11:09，Tiwei Bie <tiwei....@intel.com> 写道： On Wed, Aug 14, 2019 at 03:31:09AM +0000, He Peng wrote: Hi， We found that *rte_vhost_rx_queue_count* is not protected by vq->access_lock, and the access to vq->avail->idx is not thread-safe, since at the same time, the vq->avail might be set by *vring_invalidate* when some vhost-user messages arrived, such as VRING_SET_ADDRESS, VRING_SET_MEM_TABLE, etc. You are right. And other similar APIs also need to be protected. Thanks for reporting this! Thanks, Tiwei Thanks.
