Subject: [PATCH] security: dac: also label listen UNIX sockets

We switched to opening mode='bind' sockets ourselves:

commit 30fb2276d88b275dc2aad6ddd28c100d944b59a5
a5a3f0
    qemu: support passing pre-opened UNIX socket listen FD
a5a3f0
in v4.5.0-rc1~251
a5a3f0
a5a3f0
Then fixed qemuBuildChrChardevStr to change libvirtd's label
a5a3f0
while creating the socket:
a5a3f0
commit b0c6300fc42bbc3e5eb0b236392f7344581c5810
a5a3f0
    qemu: ensure FDs passed to QEMU for chardevs have correct SELinux labels
a5a3f0
v4.5.0-rc1~52
a5a3f0
a5a3f0
Also add labeling of these sockets to the DAC driver.
a5a3f0
Instead of duplicating the logic which decides whether libvirt should
a5a3f0
pre-create the socket, assume an existing path meaning that it was created
a5a3f0
by libvirt.
