38 * next - Next credential in the list
40 * This pointer can be used to iterate over all credentials. The head
41 * of this list is stored in the cred field of struct wpa_config.
43 struct wpa_cred *next;
46 * id - Unique id for the credential
48 * This identifier is used as a unique identifier for each credential
49 * block when using the control interface. Each credential is allocated
50 * an id when it is being created, either when reading the
51 * configuration file or when a new credential is added through the
57 * temporary - Whether this credential is temporary and not to be saved
62 * priority - Priority group
64 * By default, all networks and credentials get the same priority group
65 * (0). This field can be used to give higher priority for credentials
66 * (and similarly in struct wpa_ssid for network blocks) to change the
67 * Interworking automatic networking selection behavior. The matching
68 * network (based on either an enabled network block or a credential)
69 * with the highest priority value will be selected.
74 * pcsc - Use PC/SC and SIM/USIM card
79 * realm - Home Realm for Interworking
84 * username - Username for Interworking network selection
89 * password - Password for Interworking network selection
94 * ext_password - Whether password is a name for external storage
99 * ca_cert - CA certificate for Interworking network selection
104 * client_cert - File path to client certificate file (PEM/DER)
106 * This field is used with Interworking networking selection for a case
107 * where client certificate/private key is used for authentication
108 * (EAP-TLS). Full path to the file should be used since working
109 * directory may change when wpa_supplicant is run in the background.
111 * Alternatively, a named configuration blob can be used by setting
112 * this to blob://blob_name.
117 * private_key - File path to client private key file (PEM/DER/PFX)
119 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
120 * commented out. Both the private key and certificate will be read
121 * from the PKCS#12 file in this case. Full path to the file should be
122 * used since working directory may change when wpa_supplicant is run
125 * Windows certificate store can be used by leaving client_cert out and
126 * configuring private_key in one of the following formats:
128 * cert://substring_to_match
130 * hash://certificate_thumbprint_in_hex
132 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
134 * Note that when running wpa_supplicant as an application, the user
135 * certificate store (My user account) is used, whereas computer store
136 * (Computer account) is used when running wpasvc as a service.
138 * Alternatively, a named configuration blob can be used by setting
139 * this to blob://blob_name.

146 char *private_key_passwd;
149 * imsi - IMSI in <MCC> | <MNC> | '-' | <MSIN> format
154 * milenage - Milenage parameters for SIM/USIM simulator in
155 * <Ki>:<OPc>:<SQN> format
160 * domain_suffix_match - Constraint for server domain name
162 * If set, this FQDN is used as a suffix match requirement for the AAA
163 * server certificate in SubjectAltName dNSName element(s). If a
164 * matching dNSName is found, this constraint is met. If no dNSName
165 * values are present, this constraint is matched against SubjetName CN
166 * using same suffix match comparison. Suffix match here means that the
167 * host/domain name is compared one label at a time starting from the
168 * top-level domain and all the labels in @domain_suffix_match shall be
169 * included in the certificate. The certificate may include additional
170 * sub-level labels in addition to the required labels.
172 * For example, domain_suffix_match=example.com would match
173 * test.example.com but would not match test-example.com.
175 char *domain_suffix_match;
178 * domain - Home service provider FQDN(s)
180 * This is used to compare against the Domain Name List to figure out
181 * whether the AP is operated by the Home SP. Multiple domain entries
182 * can be used to configure alternative FQDNs that will be considered

195 * If roaming_consortium_len is non-zero, this field contains the
196 * Roaming Consortium OI that can be used to determine which access
197 * points support authentication with this credential. This is an
198 * alternative to the use of the realm parameter. When using Roaming
199 * Consortium to match the network, the EAP parameters need to be
200 * pre-configured with the credential since the NAI Realm information
201 * may not be available or fetched.

326 * more than one network interface is being controlled, one instance is used
331 * ssid - Head of the global network list
333 * This is the head for the list of all the configured networks.

345 * This indicates how many per-priority network lists are included in
351 * cred - Head of the credential list
353 * This is the head for the list of all the configured credentials.
355 struct wpa_cred *cred;
358 * eapol_version - IEEE 802.1X/EAPOL version number
360 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
361 * defines EAPOL version 2. However, there are many APs that do not
362 * handle the new version number correctly (they seem to drop the
363 * frames completely). In order to make wpa_supplicant interoperate
364 * with these APs, the version number is set to 1 by default. This
365 * configuration value can be used to set it to the new version (2).
370 * ap_scan - AP scanning/selection
372 * By default, wpa_supplicant requests driver to perform AP
373 * scanning and then uses the scan results to select a
374 * suitable AP. Another alternative is to allow the driver to
375 * take care of AP scanning and selection and use
376 * wpa_supplicant just to process EAPOL frames based on IEEE
377 * 802.11 association information from the driver.
379 * 1: wpa_supplicant initiates scanning and AP selection (default).
381 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
382 * association parameters (e.g., WPA IE generation); this mode can
383 * also be used with non-WPA drivers when using IEEE 802.1X mode;
384 * do not try to associate with APs (i.e., external program needs
385 * to control association). This mode must also be used when using
386 * wired Ethernet drivers.
388 * 2: like 0, but associate with APs using security policy and SSID
389 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
390 * drivers to enable operation with hidden SSIDs and optimized roaming;
391 * in this mode, the network blocks in the configuration are tried
392 * one by one until the driver reports successful association; each
393 * network block should have explicit security policy (i.e., only one
394 * option in the lists) for key_mgmt, pairwise, group, proto variables.
399 * bgscan - Background scan and roaming parameters or %NULL if none
401 * This is an optional set of parameters for background scanning and
402 * roaming within a network (ESS). For more detailed information see
403 * ssid block documentation.
405 * The variable defines default bgscan behavior for all BSS station
406 * networks except for those which have their own bgscan configuration.
411 * disable_scan_offload - Disable automatic offloading of scan requests
413 * By default, %wpa_supplicant tries to offload scanning if the driver
414 * indicates support for this (sched_scan). This configuration
415 * parameter can be used to disable this offloading mechanism.
417 int disable_scan_offload;
420 * ctrl_interface - Parameters for the control interface
422 * If this is specified, %wpa_supplicant will open a control interface
423 * that is available for external programs to manage %wpa_supplicant.
424 * The meaning of this string depends on which control interface
425 * mechanism is used. For all cases, the existence of this parameter
426 * in configuration is used to determine whether the control interface
429 * For UNIX domain sockets (default on Linux and BSD): This is a
430 * directory that will be created for UNIX domain sockets for listening
431 * to requests from external programs (CLI/GUI, etc.) for status
432 * information and configuration. The socket file will be named based
433 * on the interface name, so multiple %wpa_supplicant processes can be
434 * run at the same time if more than one interface is used.
435 * /var/run/wpa_supplicant is the recommended directory for sockets and
436 * by default, wpa_cli will use it when trying to connect with
439 * Access control for the control interface can be configured
440 * by setting the directory to allow only members of a group
441 * to use sockets. This way, it is possible to run
442 * %wpa_supplicant as root (since it needs to change network
443 * configuration and open raw sockets) and still allow GUI/CLI
444 * components to be run as non-root users. However, since the
445 * control interface can be used to change the network
446 * configuration, this access needs to be protected in many
447 * cases. By default, %wpa_supplicant is configured to use gid
448 * 0 (root). If you want to allow non-root users to use the
449 * control interface, add a new group and change this value to
450 * match with that group. Add users that should have control
451 * interface access to this group.
453 * When configuring both the directory and group, use following format:
454 * DIR=/var/run/wpa_supplicant GROUP=wheel
455 * DIR=/var/run/wpa_supplicant GROUP=0
456 * (group can be either group name or gid)
458 * For UDP connections (default on Windows): The value will be ignored.
459 * This variable is just used to select that the control interface is
460 * to be created. The value can be set to, e.g., udp
461 * (ctrl_interface=udp).
463 * For Windows Named Pipe: This value can be used to set the security
464 * descriptor for controlling access to the control interface. Security
465 * descriptor can be set using Security Descriptor String Format (see
466 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
467 * The descriptor string needs to be prefixed with SDDL=. For example,
468 * ctrl_interface=SDDL=D: would set an empty DACL (which will reject
471 char *ctrl_interface;
474 * ctrl_interface_group - Control interface group (DEPRECATED)
476 * This variable is only used for backwards compatibility. Group for
477 * UNIX domain sockets should now be specified using GROUP=group in
478 * ctrl_interface variable.
480 char *ctrl_interface_group;
483 * fast_reauth - EAP fast re-authentication (session resumption)
485 * By default, fast re-authentication is enabled for all EAP methods
486 * that support it. This variable can be used to disable fast
487 * re-authentication (by setting fast_reauth=0). Normally, there is no
488 * need to disable fast re-authentication.
493 * opensc_engine_path - Path to the OpenSSL engine for opensc
495 * This is an OpenSSL specific configuration option for loading OpenSC
496 * engine (engine_opensc.so); if %NULL, this engine is not loaded.

513 * module is not loaded.
515 char *pkcs11_module_path;
518 * pcsc_reader - PC/SC reader name prefix
520 * If not %NULL, PC/SC reader with a name that matches this prefix is
521 * initialized for SIM/USIM access. Empty string can be used to match
522 * the first available reader.
527 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
529 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
530 * EAP-AKA. If left out, this will be asked through control interface.
535 * external_sim - Use external processing for SIM/USIM operations
540 * driver_param - Driver interface parameters
542 * This text string is passed to the selected driver interface with the
543 * optional struct wpa_driver_ops::set_param() handler. This can be

574 * update_config - Is wpa_supplicant allowed to update configuration
576 * This variable control whether wpa_supplicant is allow to re-write
577 * its configuration with wpa_config_write(). If this is zero,
578 * configuration data is only changed in memory and the external data
579 * is not overriden. If this is non-zero, wpa_supplicant will update
580 * the configuration data (e.g., a file) whenever configuration is
581 * changed. This update may replace the old configuration which can
582 * remove comments from it in case of a text file configuration.
