[CRIU] Control messages in queue, not supported

[Daniel Drubin]

Hi,

I'm trying to use CRIU to migrate LXC containers. When dumping a
CentOS 6.5 container, I get a failure with "Control messages in queue,
not supported". By added printouts in dump sequence I found out that a
domain socket open in rsyslogd has a message of type SCM_CREDENTIALS,
which causes this failure.

Why 'SCM_CREDENTIALS' control message type is not supported? Is it a
deliberate decision or not-yet-supported?

Thanks,
Daniel
