430 *
431 * By default, wpa_supplicant requests driver to perform AP
432 * scanning and then uses the scan results to select a
433 * suitable AP. Another alternative is to allow the driver to
434 * take care of AP scanning and selection and use
435 * wpa_supplicant just to process EAPOL frames based on IEEE
436 * 802.11 association information from the driver.
437 *
438 * 1: wpa_supplicant initiates scanning and AP selection (default).
439 *
440 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
441 * association parameters (e.g., WPA IE generation); this mode can
442 * also be used with non-WPA drivers when using IEEE 802.1X mode;
443 * do not try to associate with APs (i.e., external program needs
444 * to control association). This mode must also be used when using
445 * wired Ethernet drivers.
446 *
447 * 2: like 0, but associate with APs using security policy and SSID
448 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
449 * drivers to enable operation with hidden SSIDs and optimized roaming;
450 * in this mode, the network blocks in the configuration are tried
451 * one by one until the driver reports successful association; each
452 * network block should have explicit security policy (i.e., only one
453 * option in the lists) for key_mgmt, pairwise, group, proto variables.

Dmitry Shmidt8d520ff2011-05-09 14:06:53 -0700484 * ctrl_interface - Parameters for the control interface
485 *
486 * If this is specified, %wpa_supplicant will open a control interface
487 * that is available for external programs to manage %wpa_supplicant.
488 * The meaning of this string depends on which control interface
Dmitry Shmidt1f69aa52012-01-24 16:10:04 -0800489 * mechanism is used. For all cases, the existence of this parameter
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -0700490 * in configuration is used to determine whether the control interface
491 * is enabled.
492 *
493 * For UNIX domain sockets (default on Linux and BSD): This is a
494 * directory that will be created for UNIX domain sockets for listening
495 * to requests from external programs (CLI/GUI, etc.) for status
496 * information and configuration. The socket file will be named based
497 * on the interface name, so multiple %wpa_supplicant processes can be
498 * run at the same time if more than one interface is used.
499 * /var/run/wpa_supplicant is the recommended directory for sockets and
500 * by default, wpa_cli will use it when trying to connect with
501 * %wpa_supplicant.
502 *
503 * Access control for the control interface can be configured
504 * by setting the directory to allow only members of a group
505 * to use sockets. This way, it is possible to run
506 * %wpa_supplicant as root (since it needs to change network
507 * configuration and open raw sockets) and still allow GUI/CLI
508 * components to be run as non-root users. However, since the
509 * control interface can be used to change the network
510 * configuration, this access needs to be protected in many
511 * cases. By default, %wpa_supplicant is configured to use gid
512 * 0 (root). If you want to allow non-root users to use the
513 * control interface, add a new group and change this value to
514 * match with that group. Add users that should have control
515 * interface access to this group.
516 *
517 * When configuring both the directory and group, use following format:
518 * DIR=/var/run/wpa_supplicant GROUP=wheel
519 * DIR=/var/run/wpa_supplicant GROUP=0
520 * (group can be either group name or gid)
521 *
522 * For UDP connections (default on Windows): The value will be ignored.
523 * This variable is just used to select that the control interface is
524 * to be created. The value can be set to, e.g., udp
525 * (ctrl_interface=udp).
526 *
527 * For Windows Named Pipe: This value can be used to set the security
528 * descriptor for controlling access to the control interface. Security
529 * descriptor can be set using Security Descriptor String Format (see
530 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
