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

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

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

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

515 * module is not loaded.
517 char *pkcs11_module_path;
520 * pcsc_reader - PC/SC reader name prefix
522 * If not %NULL, PC/SC reader with a name that matches this prefix is
523 * initialized for SIM/USIM access. Empty string can be used to match
524 * the first available reader.
529 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
531 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
532 * EAP-AKA. If left out, this will be asked through control interface.
537 * external_sim - Use external processing for SIM/USIM operations
542 * driver_param - Driver interface parameters
544 * This text string is passed to the selected driver interface with the
545 * optional struct wpa_driver_ops::set_param() handler. This can be
546 * used to configure driver specific options without having to add new
547 * driver interface functionality.

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

818 * Homogeneous ESS. This is used only if interworking is enabled.
828 * pbc_in_m1 - AP mode WPS probing workaround for PBC with Windows 7
830 * Windows 7 uses incorrect way of figuring out AP's WPS capabilities
831 * by acting as a Registrar and using M1 from the AP. The config
832 * methods attribute in that message is supposed to indicate only the
833 * configuration method supported by the AP in Enrollee role, i.e., to
834 * add an external Registrar. For that case, PBC shall not be used and
835 * as such, the PushButton config method is removed from M1 by default.
836 * If pbc_in_m1=1 is included in the configuration file, the PushButton
837 * config method is left in M1 (if included in config_methods
838 * parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from
839 * a label in the AP).

913 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
914 * Note that regulatory constraints and driver capabilities are
915 * consulted anyway, so setting it to 1 can't do real harm.
916 * By default: 0 (disabled)
921 * p2p_go_vht - Default mode for VHT enable when operating as GO
923 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.

936 * p2p_no_group_iface - Whether group interfaces can be used
938 * By default, wpa_supplicant will create a separate interface for P2P
939 * group operations if the driver supports this. This functionality can
940 * be disabled by setting this parameter to 1. In that case, the same
941 * interface that was used for the P2P management operations is used
942 * also for the group operation.

956 * pmf - Whether to enable/require PMF by default
958 * By default, PMF is disabled unless enabled by the per-network

965 * sae_groups - Preference list of enabled groups for SAE
967 * By default (if this parameter is not set), the mandatory group 19
968 * (ECC group defined over a 256-bit prime order field) is preferred,
969 * but other groups are also enabled. If this parameter is set, the
970 * groups will be tried in the indicated order.
975 * dtim_period - Default DTIM period in Beacon intervals
977 * This parameter can be used to set the default value for network
978 * blocks that do not specify dtim_period.
