52 * next - Next credential in the list
54 * This pointer can be used to iterate over all credentials. The head
55 * of this list is stored in the cred field of struct wpa_config.
57 struct wpa_cred *next;
60 * id - Unique id for the credential
62 * This identifier is used as a unique identifier for each credential
63 * block when using the control interface. Each credential is allocated
64 * an id when it is being created, either when reading the
65 * configuration file or when a new credential is added through the
71 * temporary - Whether this credential is temporary and not to be saved
76 * priority - Priority group
78 * By default, all networks and credentials get the same priority group
79 * (0). This field can be used to give higher priority for credentials
80 * (and similarly in struct wpa_ssid for network blocks) to change the
81 * Interworking automatic networking selection behavior. The matching
82 * network (based on either an enabled network block or a credential)
83 * with the highest priority value will be selected.
88 * pcsc - Use PC/SC and SIM/USIM card
93 * realm - Home Realm for Interworking
98 * username - Username for Interworking network selection
103 * password - Password for Interworking network selection
108 * ext_password - Whether password is a name for external storage
113 * ca_cert - CA certificate for Interworking network selection
118 * client_cert - File path to client certificate file (PEM/DER)
120 * This field is used with Interworking networking selection for a case
121 * where client certificate/private key is used for authentication
122 * (EAP-TLS). Full path to the file should be used since working
123 * directory may change when wpa_supplicant is run in the background.
125 * Alternatively, a named configuration blob can be used by setting
126 * this to blob://blob_name.
131 * private_key - File path to client private key file (PEM/DER/PFX)
133 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
134 * commented out. Both the private key and certificate will be read
135 * from the PKCS#12 file in this case. Full path to the file should be
136 * used since working directory may change when wpa_supplicant is run
139 * Windows certificate store can be used by leaving client_cert out and
140 * configuring private_key in one of the following formats:
142 * cert://substring_to_match
144 * hash://certificate_thumbprint_in_hex
146 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
148 * Note that when running wpa_supplicant as an application, the user
149 * certificate store (My user account) is used, whereas computer store
150 * (Computer account) is used when running wpasvc as a service.
152 * Alternatively, a named configuration blob can be used by setting
153 * this to blob://blob_name.
158 * private_key_passwd - Password for private key file
160 char *private_key_passwd;
163 * imsi - IMSI in <MCC> | <MNC> | '-' | <MSIN> format
168 * milenage - Milenage parameters for SIM/USIM simulator in
169 * <Ki>:<OPc>:<SQN> format
174 * domain_suffix_match - Constraint for server domain name
176 * If set, this FQDN is used as a suffix match requirement for the AAA
177 * server certificate in SubjectAltName dNSName element(s). If a
178 * matching dNSName is found, this constraint is met. If no dNSName
179 * values are present, this constraint is matched against SubjectName CN
180 * using same suffix match comparison. Suffix match here means that the
181 * host/domain name is compared one label at a time starting from the
182 * top-level domain and all the labels in @domain_suffix_match shall be
183 * included in the certificate. The certificate may include additional
184 * sub-level labels in addition to the required labels.
186 * For example, domain_suffix_match=example.com would match
187 * test.example.com but would not match test-example.com.
189 char *domain_suffix_match;
192 * domain - Home service provider FQDN(s)
194 * This is used to compare against the Domain Name List to figure out
195 * whether the AP is operated by the Home SP. Multiple domain entries
196 * can be used to configure alternative FQDNs that will be considered
202 * num_domain - Number of FQDNs in the domain array
207 * roaming_consortium - Roaming Consortium OI
209 * If roaming_consortium_len is non-zero, this field contains the
210 * Roaming Consortium OI that can be used to determine which access
211 * points support authentication with this credential. This is an
212 * alternative to the use of the realm parameter. When using Roaming
213 * Consortium to match the network, the EAP parameters need to be
214 * pre-configured with the credential since the NAI Realm information
215 * may not be available or fetched.

338 * struct wpa_config - wpa_supplicant configuration data
340 * This data structure is presents the per-interface (radio) configuration
341 * data. In many cases, there is only one struct wpa_config instance, but if
342 * more than one network interface is being controlled, one instance is used
347 * ssid - Head of the global network list
349 * This is the head for the list of all the configured networks.
351 struct wpa_ssid *ssid;
354 * pssid - Per-priority network lists (in priority order)
356 struct wpa_ssid **pssid;
359 * num_prio - Number of different priorities used in the pssid lists
361 * This indicates how many per-priority network lists are included in
367 * cred - Head of the credential list
369 * This is the head for the list of all the configured credentials.
371 struct wpa_cred *cred;
374 * eapol_version - IEEE 802.1X/EAPOL version number
376 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
377 * defines EAPOL version 2. However, there are many APs that do not
378 * handle the new version number correctly (they seem to drop the
379 * frames completely). In order to make wpa_supplicant interoperate
380 * with these APs, the version number is set to 1 by default. This
381 * configuration value can be used to set it to the new version (2).
386 * ap_scan - AP scanning/selection
388 * By default, wpa_supplicant requests driver to perform AP
389 * scanning and then uses the scan results to select a
390 * suitable AP. Another alternative is to allow the driver to
391 * take care of AP scanning and selection and use
392 * wpa_supplicant just to process EAPOL frames based on IEEE
393 * 802.11 association information from the driver.
395 * 1: wpa_supplicant initiates scanning and AP selection (default).
397 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
398 * association parameters (e.g., WPA IE generation); this mode can
399 * also be used with non-WPA drivers when using IEEE 802.1X mode;
400 * do not try to associate with APs (i.e., external program needs
401 * to control association). This mode must also be used when using
402 * wired Ethernet drivers.
404 * 2: like 0, but associate with APs using security policy and SSID
405 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
406 * drivers to enable operation with hidden SSIDs and optimized roaming;
407 * in this mode, the network blocks in the configuration are tried
408 * one by one until the driver reports successful association; each
409 * network block should have explicit security policy (i.e., only one
410 * option in the lists) for key_mgmt, pairwise, group, proto variables.
412 * Note: ap_scan=2 should not be used with the nl80211 driver interface
413 * (the current Linux interface). ap_scan=1 is optimized work working
414 * with nl80211. For finding networks using hidden SSID, scan_ssid=1 in
415 * the network block can be used with nl80211.
420 * bgscan - Background scan and roaming parameters or %NULL if none
422 * This is an optional set of parameters for background scanning and
423 * roaming within a network (ESS). For more detailed information see
424 * ssid block documentation.
426 * The variable defines default bgscan behavior for all BSS station
427 * networks except for those which have their own bgscan configuration.
432 * disable_scan_offload - Disable automatic offloading of scan requests
434 * By default, %wpa_supplicant tries to offload scanning if the driver
435 * indicates support for this (sched_scan). This configuration
436 * parameter can be used to disable this offloading mechanism.
438 int disable_scan_offload;
441 * ctrl_interface - Parameters for the control interface
443 * If this is specified, %wpa_supplicant will open a control interface
444 * that is available for external programs to manage %wpa_supplicant.
445 * The meaning of this string depends on which control interface
446 * mechanism is used. For all cases, the existence of this parameter
447 * in configuration is used to determine whether the control interface
450 * For UNIX domain sockets (default on Linux and BSD): This is a
451 * directory that will be created for UNIX domain sockets for listening
452 * to requests from external programs (CLI/GUI, etc.) for status
453 * information and configuration. The socket file will be named based
454 * on the interface name, so multiple %wpa_supplicant processes can be
455 * run at the same time if more than one interface is used.
456 * /var/run/wpa_supplicant is the recommended directory for sockets and
457 * by default, wpa_cli will use it when trying to connect with
460 * Access control for the control interface can be configured
461 * by setting the directory to allow only members of a group
462 * to use sockets. This way, it is possible to run
463 * %wpa_supplicant as root (since it needs to change network
464 * configuration and open raw sockets) and still allow GUI/CLI
465 * components to be run as non-root users. However, since the
466 * control interface can be used to change the network
467 * configuration, this access needs to be protected in many
468 * cases. By default, %wpa_supplicant is configured to use gid
469 * 0 (root). If you want to allow non-root users to use the
470 * control interface, add a new group and change this value to
471 * match with that group. Add users that should have control
472 * interface access to this group.
474 * When configuring both the directory and group, use following format:
475 * DIR=/var/run/wpa_supplicant GROUP=wheel
476 * DIR=/var/run/wpa_supplicant GROUP=0
477 * (group can be either group name or gid)
479 * For UDP connections (default on Windows): The value will be ignored.
480 * This variable is just used to select that the control interface is
481 * to be created. The value can be set to, e.g., udp
482 * (ctrl_interface=udp).
484 * For Windows Named Pipe: This value can be used to set the security
485 * descriptor for controlling access to the control interface. Security
486 * descriptor can be set using Security Descriptor String Format (see
487 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
488 * The descriptor string needs to be prefixed with SDDL=. For example,
489 * ctrl_interface=SDDL=D: would set an empty DACL (which will reject
492 char *ctrl_interface;
495 * ctrl_interface_group - Control interface group (DEPRECATED)
497 * This variable is only used for backwards compatibility. Group for
498 * UNIX domain sockets should now be specified using GROUP=group in
499 * ctrl_interface variable.
501 char *ctrl_interface_group;
504 * fast_reauth - EAP fast re-authentication (session resumption)
506 * By default, fast re-authentication is enabled for all EAP methods
507 * that support it. This variable can be used to disable fast
508 * re-authentication (by setting fast_reauth=0). Normally, there is no
509 * need to disable fast re-authentication.
514 * opensc_engine_path - Path to the OpenSSL engine for opensc

539 * openssl_ciphers - OpenSSL cipher string
541 * This is an OpenSSL specific configuration option for configuring the
542 * default ciphers. If not set, "DEFAULT:!EXP:!LOW" is used as the

548 * pcsc_reader - PC/SC reader name prefix
550 * If not %NULL, PC/SC reader with a name that matches this prefix is
551 * initialized for SIM/USIM access. Empty string can be used to match
552 * the first available reader.
557 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
559 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
560 * EAP-AKA. If left out, this will be asked through control interface.
565 * external_sim - Use external processing for SIM/USIM operations
570 * driver_param - Driver interface parameters
572 * This text string is passed to the selected driver interface with the
573 * optional struct wpa_driver_ops::set_param() handler. This can be

604 * update_config - Is wpa_supplicant allowed to update configuration
606 * This variable control whether wpa_supplicant is allow to re-write
607 * its configuration with wpa_config_write(). If this is zero,
608 * configuration data is only changed in memory and the external data
609 * is not overriden. If this is non-zero, wpa_supplicant will update
610 * the configuration data (e.g., a file) whenever configuration is

805 * If the BSS entry has not been seen in this many scans, it will be
806 * removed. A value of 1 means that entry is removed after the first
807 * scan in which the BSSID is not seen. Larger values can be used
808 * to avoid BSS entries disappearing if they are not visible in

897 * If pbc_in_m1=1 is included in the configuration file, the PushButton
898 * config method is left in M1 (if included in config_methods
899 * parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from
900 * a label in the AP).

1016 * p2p_cli_probe - Enable/disable P2P CLI probe request handling
1018 * If this parameter is set to 1, a connected P2P Client will receive
1019 * and handle Probe Request frames. Setting this parameter to 0

1218 * passive_scan - Whether to force passive scan for network connection
1220 * This parameter can be used to force only passive scanning to be used
1221 * for network connection cases. It should be noted that this will slow
1222 * down scan operations and reduce likelihood of finding the AP. In
