O-Subject: [RHEL-8.0/AV qemu-kvm PATCH 1/1] io: ensure UNIX client doesn't unlink server socket
Bugzilla: 1665896
RH-Acked-by: John Snow <jsnow@redhat.com>

The qio_channel_socket_close method for was mistakenly unlinking the
UNIX server socket, even if the channel was a client connection. This
was not noticed with chardevs, since they never call close, but with the
VNC server, this caused the VNC server socket to be deleted after the
first client quit.
The qio_channel_socket_close method also needlessly reimplemented the
logic that already exists in socket_listen_cleanup(). Just call that
method directly, for listen sockets only.
This fixes a regression introduced in QEMU 3.0.0 with
commit d66f78e1eaa832f73c771d9df1b606fe75d52a50

The new device_id property specifies which value to use for the vendor
specific designator in the Device Identification VPD page.
In particular, this is necessary for libvirt to maintain guest ABI
compatibility when no serial number is given and a VM is switched from
-drive (where the BlockBackend name is used) to -blockdev (where the
vendor specific designator is left out by default).

scsi-disk includes in the Device Identification VPD page, depending on
configuration amongst others, a vendor specific designator that consists
either of the serial number if given or the BlockBackend name (which is
a host detail that better shouldn't have been leaked to the guest, but
now we have to maintain it for compatibility).
With anonymous BlockBackends, i.e. scsi-disk devices constructed with
drive=<node-name>, and no serial number explicitly specified, this ends
up as an empty string. If this happens to more than one disk, we have
accidentally signalled to the OS that this is a multipath setup, which
is obviously not what was intended.
Instead of using an empty string for the vendor specific designator,
simply leave out that designator, which makes Linux detect such setups
as separate disks again.
