dpdk: sending vhost-user-inflight type messages could lead to DoS

A flaw was found in dpdk, which allows a malicious primary vhost-user to attach an unexpected number of fds as ancillary data to VHOSTUSERGETINFLIGHTFD / VHOSTUSERSETINFLIGHTFD messages that are not closed by the secondary vhost-user. By sending such messages continuously, the primary vhost-user...
