    logging: restrict sockets to mode 0600
    
    The virtlogd daemon's only intended client is the libvirtd daemon. As
    such it should never allow clients from other user accounts to connect.
    The code already enforces this and drops clients from other UIDs, but
    we can get earlier (and thus stronger) protection against DoS by setting
    the socket permissions to 0600
    
    Fixes CVE-2019-10132
