[Qemu-devel] [PATCH STABLE 1/2] net: Fix -net socket, listen (Jan Kiszka)

[Glauber Costa <glommer@redhat.com>]

From: aliguori <aliguori@c046a42c-6fe2-441c-8c8c-71466251a162>

In case no symbolic name is provided when requesting VLAN connection via
listening TCP socket ('-net socket,listen=...'), qemu crashes. This
fixes the cause.
