[dpdk-dev] [PATCH v3 0/6] net/virtio-user: fix server mode

[Adrian Moreno]

A number of issues have been detected that currently break virtio-user
server mode.
This series addresses such issues.
Note that virtio-user server mode is broken by design and many of the
problems that it currently has should be fixed by a bigger rework.

--
v2->v3:
Fix potential concurrency problem on get/set state
Handle STATUS protocol feature flag
Fix undefined behaviour if STATUS feature is not supported
Ensure packed virtqueues are reset on reconnection


v1->v2:
Added patch 2 and 3 addressing additional issues
Check errno to select vhost-user backend and log the detected backend
type

Adrian Moreno (6):
  net/virtio-user: fix backend selection if stat fails
  net/virtio-user: don't set/get_status until FEATURES_OK
  net/virtio-user: ignore result if STATUS is unsupported
  net/virtio-user: lock-protect status updates
  net/virtio-user: don't assume vhost status feature
  net/virtio-user: set status on socket reconnect
