This patches fixes virtqueue initialization issue causing segfault or file descriptor being closed unexpectedly.The wrong index was passed to init_vring_queue() by alloc_vring_queue() when a hole in the virtqueue array was met. Fixes: 8acd7c213353 ("vhost: fix virtqueues metadata allocation") Cc: sta...@dpdk.org
Since the issue is introduced in this release, there is nothing to backport and stable tag is not required, removing it in next-net.
