552 	 * The meaning of this string depends on which control interface

555 	 * is enabled.

557 	 * For UNIX domain sockets (default on Linux and BSD): This is a
558 	 * directory that will be created for UNIX domain sockets for listening
559 	 * to requests from external programs (CLI/GUI, etc.) for status
560 	 * information and configuration. The socket file will be named based
561 	 * on the interface name, so multiple %wpa_supplicant processes can be
562 	 * run at the same time if more than one interface is used.
563 	 * /var/run/wpa_supplicant is the recommended directory for sockets and
564 	 * by default, wpa_cli will use it when trying to connect with
565 	 * %wpa_supplicant.
566 	 *
567 	 * Access control for the control interface can be configured
568 	 * by setting the directory to allow only members of a group
569 	 * to use sockets. This way, it is possible to run
570 	 * %wpa_supplicant as root (since it needs to change network
571 	 * configuration and open raw sockets) and still allow GUI/CLI
572 	 * components to be run as non-root users. However, since the
573 	 * control interface can be used to change the network
574 	 * configuration, this access needs to be protected in many
575 	 * cases. By default, %wpa_supplicant is configured to use gid
576 	 * 0 (root). If you want to allow non-root users to use the
577 	 * control interface, add a new group and change this value to
578 	 * match with that group. Add users that should have control
579 	 * interface access to this group.

581 	 * When configuring both the directory and group, use following format:

589 	 * (ctrl_interface=udp).

591 	 * For Windows Named Pipe: This value can be used to set the security
592 	 * descriptor for controlling access to the control interface. Security
593 	 * descriptor can be set using Security Descriptor String Format (see
