42 * next - Next credential in the list
44 * This pointer can be used to iterate over all credentials. The head
45 * of this list is stored in the cred field of struct wpa_config.
47 struct wpa_cred
*next
;
50 * id - Unique id for the credential
52 * This identifier is used as a unique identifier for each credential
53 * block when using the control interface. Each credential is allocated
54 * an id when it is being created, either when reading the
55 * configuration file or when a new credential is added through the
61 * temporary - Whether this credential is temporary and not to be saved
66 * priority - Priority group
68 * By default, all networks and credentials get the same priority group
69 * (0). This field can be used to give higher priority for credentials
70 * (and similarly in struct wpa_ssid for network blocks) to change the
71 * Interworking automatic networking selection behavior. The matching
72 * network (based on either an enabled network block or a credential)
73 * with the highest priority value will be selected.
78 * pcsc - Use PC/SC and SIM/USIM card
83 * realm - Home Realm for Interworking
88 * username - Username for Interworking network selection
93 * password - Password for Interworking network selection
98 * ext_password - Whether password is a name for external storage
103 * ca_cert - CA certificate for Interworking network selection
108 * client_cert - File path to client certificate file (PEM/DER)
110 * This field is used with Interworking networking selection for a case
111 * where client certificate/private key is used for authentication
112 * (EAP-TLS). Full path to the file should be used since working
113 * directory may change when wpa_supplicant is run in the background.
115 * Alternatively, a named configuration blob can be used by setting
116 * this to blob://blob_name.
121 * private_key - File path to client private key file (PEM/DER/PFX)
123 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
124 * commented out. Both the private key and certificate will be read
125 * from the PKCS#12 file in this case. Full path to the file should be
126 * used since working directory may change when wpa_supplicant is run
129 * Windows certificate store can be used by leaving client_cert out and
130 * configuring private_key in one of the following formats:
132 * cert://substring_to_match
134 * hash://certificate_thumbprint_in_hex
136 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
138 * Note that when running wpa_supplicant as an application, the user
139 * certificate store (My user account) is used, whereas computer store
140 * (Computer account) is used when running wpasvc as a service.
142 * Alternatively, a named configuration blob can be used by setting
143 * this to blob://blob_name.

158 * milenage - Milenage parameters for SIM/USIM simulator in
159 * <Ki>:<OPc>:<SQN> format
164 * domain_suffix_match - Constraint for server domain name
166 * If set, this FQDN is used as a suffix match requirement for the AAA
167 * server certificate in SubjectAltName dNSName element(s). If a
168 * matching dNSName is found, this constraint is met. If no dNSName
169 * values are present, this constraint is matched against SubjetName CN
170 * using same suffix match comparison. Suffix match here means that the
171 * host/domain name is compared one label at a time starting from the
172 * top-level domain and all the labels in @domain_suffix_match shall be
173 * included in the certificate. The certificate may include additional
174 * sub-level labels in addition to the required labels.
176 * For example, domain_suffix_match=example.com would match
177 * test.example.com but would not match test-example.com.

363 * eapol_version - IEEE 802.1X/EAPOL version number
365 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
366 * defines EAPOL version 2. However, there are many APs that do not
367 * handle the new version number correctly (they seem to drop the
368 * frames completely). In order to make wpa_supplicant interoperate
369 * with these APs, the version number is set to 1 by default. This
370 * configuration value can be used to set it to the new version (2).
375 * ap_scan - AP scanning/selection
377 * By default, wpa_supplicant requests driver to perform AP
378 * scanning and then uses the scan results to select a
379 * suitable AP. Another alternative is to allow the driver to
380 * take care of AP scanning and selection and use
381 * wpa_supplicant just to process EAPOL frames based on IEEE
382 * 802.11 association information from the driver.
384 * 1: wpa_supplicant initiates scanning and AP selection (default).
386 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
387 * association parameters (e.g., WPA IE generation); this mode can
388 * also be used with non-WPA drivers when using IEEE 802.1X mode;
389 * do not try to associate with APs (i.e., external program needs
390 * to control association). This mode must also be used when using
391 * wired Ethernet drivers.
393 * 2: like 0, but associate with APs using security policy and SSID
394 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
395 * drivers to enable operation with hidden SSIDs and optimized roaming;
396 * in this mode, the network blocks in the configuration are tried
397 * one by one until the driver reports successful association; each
398 * network block should have explicit security policy (i.e., only one
399 * option in the lists) for key_mgmt, pairwise, group, proto variables.
404 * bgscan - Background scan and roaming parameters or %NULL if none
406 * This is an optional set of parameters for background scanning and
407 * roaming within a network (ESS). For more detailed information see
408 * ssid block documentation.
410 * The variable defines default bgscan behavior for all BSS station
411 * networks except for those which have their own bgscan configuration.
416 * disable_scan_offload - Disable automatic offloading of scan requests
418 * By default, %wpa_supplicant tries to offload scanning if the driver
419 * indicates support for this (sched_scan). This configuration
420 * parameter can be used to disable this offloading mechanism.
422 int disable_scan_offload
;
425 * ctrl_interface - Parameters for the control interface
427 * If this is specified, %wpa_supplicant will open a control interface
428 * that is available for external programs to manage %wpa_supplicant.
429 * The meaning of this string depends on which control interface
430 * mechanism is used. For all cases, the existence of this parameter
431 * in configuration is used to determine whether the control interface
434 * For UNIX domain sockets (default on Linux and BSD): This is a
435 * directory that will be created for UNIX domain sockets for listening
436 * to requests from external programs (CLI/GUI, etc.) for status
437 * information and configuration. The socket file will be named based
438 * on the interface name, so multiple %wpa_supplicant processes can be
439 * run at the same time if more than one interface is used.
440 * /var/run/wpa_supplicant is the recommended directory for sockets and
441 * by default, wpa_cli will use it when trying to connect with
444 * Access control for the control interface can be configured
445 * by setting the directory to allow only members of a group
446 * to use sockets. This way, it is possible to run
447 * %wpa_supplicant as root (since it needs to change network
448 * configuration and open raw sockets) and still allow GUI/CLI
449 * components to be run as non-root users. However, since the
450 * control interface can be used to change the network
451 * configuration, this access needs to be protected in many
452 * cases. By default, %wpa_supplicant is configured to use gid
453 * 0 (root). If you want to allow non-root users to use the
454 * control interface, add a new group and change this value to
455 * match with that group. Add users that should have control
456 * interface access to this group.
458 * When configuring both the directory and group, use following format:
459 * DIR=/var/run/wpa_supplicant GROUP=wheel
460 * DIR=/var/run/wpa_supplicant GROUP=0
461 * (group can be either group name or gid)
463 * For UDP connections (default on Windows): The value will be ignored.
464 * This variable is just used to select that the control interface is
465 * to be created. The value can be set to, e.g., udp
466 * (ctrl_interface=udp).
468 * For Windows Named Pipe: This value can be used to set the security
469 * descriptor for controlling access to the control interface. Security
470 * descriptor can be set using Security Descriptor String Format (see
471 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
472 * The descriptor string needs to be prefixed with SDDL=. For example,
473 * ctrl_interface=SDDL=D: would set an empty DACL (which will reject
476 char *ctrl_interface

479 * ctrl_interface_group - Control interface group (DEPRECATED)
481 * This variable is only used for backwards compatibility. Group for
482 * UNIX domain sockets should now be specified using GROUP=group in
483 * ctrl_interface variable.
485 char *ctrl_interface_group
;
488 * fast_reauth - EAP fast re-authentication (session resumption)
490 * By default, fast re-authentication is enabled for all EAP methods
491 * that support it. This variable can be used to disable fast
492 * re-authentication (by setting fast_reauth=0). Normally, there is no
493 * need to disable fast re-authentication.

845 * configuration method supported by the AP in Enrollee role, i.e., to
846 * add an external Registrar. For that case, PBC shall not be used and
847 * as such, the PushButton config method is removed from M1 by default.
848 * If pbc_in_m1=1 is included in the configuration file, the PushButton
849 * config method is left in M1 (if included in config_methods

933 * p2p_go_vht - Default mode for VHT enable when operating as GO
935 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
