982648 |
When support was adding for passing a pre-opened listener socket to UNIX
|
|
|
982648 |
chardevs, it accidentally passed the listener socket for client mode
|
|
|
982648 |
chardevs too with predictable amounts of fail resulting. This affects
|
|
|
982648 |
libvirt when using QEMU >= 2.12
|
|
|
982648 |
|
|
|
982648 |
Expand the unit test coverage to validate that we are only doing FD
|
|
|
982648 |
passing when operating in server mode.
