35 * next - Next credential in the list
37 * This pointer can be used to iterate over all credentials. The head
38 * of this list is stored in the cred field of struct wpa_config.
40 struct wpa_cred *next;
43 * id - Unique id for the credential
45 * This identifier is used as a unique identifier for each credential
46 * block when using the control interface. Each credential is allocated
47 * an id when it is being created, either when reading the
48 * configuration file or when a new credential is added through the
54 * priority - Priority group
56 * By default, all networks and credentials get the same priority group
57 * (0). This field can be used to give higher priority for credentials
58 * (and similarly in struct wpa_ssid for network blocks) to change the
59 * Interworking automatic networking selection behavior. The matching
60 * network (based on either an enabled network block or a credential)
61 * with the highest priority value will be selected.
66 * pcsc - Use PC/SC and SIM/USIM card
71 * realm - Home Realm for Interworking
76 * username - Username for Interworking network selection
81 * password - Password for Interworking network selection
86 * ext_password - Whether password is a name for external storage
91 * ca_cert - CA certificate for Interworking network selection
96 * client_cert - File path to client certificate file (PEM/DER)
98 * This field is used with Interworking networking selection for a case
99 * where client certificate/private key is used for authentication
100 * (EAP-TLS). Full path to the file should be used since working
101 * directory may change when wpa_supplicant is run in the background.
103 * Alternatively, a named configuration blob can be used by setting
104 * this to blob://blob_name.
109 * private_key - File path to client private key file (PEM/DER/PFX)
111 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
112 * commented out. Both the private key and certificate will be read
113 * from the PKCS#12 file in this case. Full path to the file should be
114 * used since working directory may change when wpa_supplicant is run
117 * Windows certificate store can be used by leaving client_cert out and
118 * configuring private_key in one of the following formats:
120 * cert://substring_to_match
122 * hash://certificate_thumbprint_in_hex
124 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
126 * Note that when running wpa_supplicant as an application, the user
127 * certificate store (My user account) is used, whereas computer store
128 * (Computer account) is used when running wpasvc as a service.
130 * Alternatively, a named configuration blob can be used by setting
131 * this to blob://blob_name.

152 * domain - Home service provider FQDN
154 * This is used to compare against the Domain Name List to figure out
155 * whether the AP is operated by the Home SP.
160 * roaming_consortium - Roaming Consortium OI
162 * If roaming_consortium_len is non-zero, this field contains the
163 * Roaming Consortium OI that can be used to determine which access
164 * points support authentication with this credential. This is an
165 * alternative to the use of the realm parameter. When using Roaming
166 * Consortium to match the network, the EAP parameters need to be
167 * pre-configured with the credential since the NAI Realm information
168 * may not be available or fetched.
170 u8 roaming_consortium[15];
173 * roaming_consortium_len - Length of roaming_consortium
175 size_t roaming_consortium_len;

226 * struct wpa_config - wpa_supplicant configuration data
228 * This data structure is presents the per-interface (radio) configuration
229 * data. In many cases, there is only one struct wpa_config instance, but if
230 * more than one network interface is being controlled, one instance is used

257 * This is the head for the list of all the configured credentials.
259 struct wpa_cred *cred;
262 * eapol_version - IEEE 802.1X/EAPOL version number
264 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
265 * defines EAPOL version 2. However, there are many APs that do not
266 * handle the new version number correctly (they seem to drop the
267 * frames completely). In order to make wpa_supplicant interoperate
268 * with these APs, the version number is set to 1 by default. This
269 * configuration value can be used to set it to the new version (2).
274 * ap_scan - AP scanning/selection
276 * By default, wpa_supplicant requests driver to perform AP
277 * scanning and then uses the scan results to select a
278 * suitable AP. Another alternative is to allow the driver to
279 * take care of AP scanning and selection and use
280 * wpa_supplicant just to process EAPOL frames based on IEEE
281 * 802.11 association information from the driver.
283 * 1: wpa_supplicant initiates scanning and AP selection (default).
285 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
286 * association parameters (e.g., WPA IE generation); this mode can
287 * also be used with non-WPA drivers when using IEEE 802.1X mode;
288 * do not try to associate with APs (i.e., external program needs
289 * to control association). This mode must also be used when using
290 * wired Ethernet drivers.
292 * 2: like 0, but associate with APs using security policy and SSID
293 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
294 * drivers to enable operation with hidden SSIDs and optimized roaming;
295 * in this mode, the network blocks in the configuration are tried
296 * one by one until the driver reports successful association; each
297 * network block should have explicit security policy (i.e., only one
298 * option in the lists) for key_mgmt, pairwise, group, proto variables.
303 * disable_scan_offload - Disable automatic offloading of scan requests
305 * By default, %wpa_supplicant tries to offload scanning if the driver
306 * indicates support for this (sched_scan). This configuration
307 * parameter can be used to disable this offloading mechanism.
309 int disable_scan_offload;
312 * ctrl_interface - Parameters for the control interface
314 * If this is specified, %wpa_supplicant will open a control interface
315 * that is available for external programs to manage %wpa_supplicant.
316 * The meaning of this string depends on which control interface
317 * mechanism is used. For all cases, the existence of this parameter
318 * in configuration is used to determine whether the control interface
321 * For UNIX domain sockets (default on Linux and BSD): This is a
322 * directory that will be created for UNIX domain sockets for listening
323 * to requests from external programs (CLI/GUI, etc.) for status
324 * information and configuration. The socket file will be named based
325 * on the interface name, so multiple %wpa_supplicant processes can be
326 * run at the same time if more than one interface is used.
327 * /var/run/wpa_supplicant is the recommended directory for sockets and
328 * by default, wpa_cli will use it when trying to connect with
331 * Access control for the control interface can be configured
332 * by setting the directory to allow only members of a group
333 * to use sockets. This way, it is possible to run
334 * %wpa_supplicant as root (since it needs to change network
335 * configuration and open raw sockets) and still allow GUI/CLI
336 * components to be run as non-root users. However, since the
337 * control interface can be used to change the network
338 * configuration, this access needs to be protected in many
339 * cases. By default, %wpa_supplicant is configured to use gid
340 * 0 (root). If you want to allow non-root users to use the
341 * control interface, add a new group and change this value to
342 * match with that group. Add users that should have control
343 * interface access to this group.
345 * When configuring both the directory and group, use following format:
346 * DIR=/var/run/wpa_supplicant GROUP=wheel
347 * DIR=/var/run/wpa_supplicant GROUP=0
348 * (group can be either group name or gid)
350 * For UDP connections (default on Windows): The value will be ignored.
351 * This variable is just used to select that the control interface is
352 * to be created. The value can be set to, e.g., udp
353 * (ctrl_interface=udp).
355 * For Windows Named Pipe: This value can be used to set the security
356 * descriptor for controlling access to the control interface. Security
357 * descriptor can be set using Security Descriptor String Format (see
358 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
359 * The descriptor string needs to be prefixed with SDDL=. For example,
360 * ctrl_interface=SDDL=D: would set an empty DACL (which will reject
363 char *ctrl_interface;
366 * ctrl_interface_group - Control interface group (DEPRECATED)
368 * This variable is only used for backwards compatibility. Group for
369 * UNIX domain sockets should now be specified using GROUP=group in
370 * ctrl_interface variable.
372 char *ctrl_interface_group;
375 * fast_reauth - EAP fast re-authentication (session resumption)
377 * By default, fast re-authentication is enabled for all EAP methods
378 * that support it. This variable can be used to disable fast
379 * re-authentication (by setting fast_reauth=0). Normally, there is no
380 * need to disable fast re-authentication.
385 * opensc_engine_path - Path to the OpenSSL engine for opensc
387 * This is an OpenSSL specific configuration option for loading OpenSC
388 * engine (engine_opensc.so); if %NULL, this engine is not loaded.

405 * module is not loaded.
407 char *pkcs11_module_path;
410 * pcsc_reader - PC/SC reader name prefix
412 * If not %NULL, PC/SC reader with a name that matches this prefix is
413 * initialized for SIM/USIM access. Empty string can be used to match
414 * the first available reader.
419 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
421 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
422 * EAP-AKA. If left out, this will be asked through control interface.
427 * driver_param - Driver interface parameters
429 * This text string is passed to the selected driver interface with the
430 * optional struct wpa_driver_ops::set_param() handler. This can be
431 * used to configure driver specific options without having to add new
432 * driver interface functionality.

453 * dot11RSNAConfigSATimeout - Security association timeout
455 * dot11 MIB variable for the maximum time a security association
456 * shall take to set up (unit: seconds).
458 unsigned int dot11RSNAConfigSATimeout;
461 * update_config - Is wpa_supplicant allowed to update configuration
463 * This variable control whether wpa_supplicant is allow to re-write
464 * its configuration with wpa_config_write(). If this is zero,
465 * configuration data is only changed in memory and the external data
466 * is not overriden. If this is non-zero, wpa_supplicant will update
467 * the configuration data (e.g., a file) whenever configuration is
468 * changed. This update may replace the old configuration which can
469 * remove comments from it in case of a text file configuration.

585 * p2p_group_idle - Maximum idle time in seconds for P2P group
587 * This value controls how long a P2P group is maintained after there
588 * is no other members in the group. As a GO, this means no associated
589 * stations in the group. As a P2P client, this means no GO seen in
590 * scan results. The maximum idle time is specified in seconds with 0
591 * indicating no time limit, i.e., the P2P group remains in active
592 * state indefinitely until explicitly removed. As a P2P client, the
593 * maximum idle time of P2P_MAX_CLIENT_IDLE seconds is enforced, i.e.,
594 * this parameter is mainly meant for GO use and for P2P client, it can
595 * only be used to reduce the default timeout to smaller value. A

616 * bss_expiration_scan_count - Expire BSS after number of scans
618 * If the BSS entry has not been seen in this many scans, it will be
619 * removed. A value of 1 means that entry is removed after the first
620 * scan in which the BSSID is not seen. Larger values can be used

676 * Homogeneous ESS. This is used only if interworking is enabled.
686 * pbc_in_m1 - AP mode WPS probing workaround for PBC with Windows 7
688 * Windows 7 uses incorrect way of figuring out AP's WPS capabilities
689 * by acting as a Registrar and using M1 from the AP. The config
690 * methods attribute in that message is supposed to indicate only the
691 * configuration method supported by the AP in Enrollee role, i.e., to
692 * add an external Registrar. For that case, PBC shall not be used and
693 * as such, the PushButton config method is removed from M1 by default.
694 * If pbc_in_m1=1 is included in the configuration file, the PushButton
695 * config method is left in M1 (if included in config_methods

779 * p2p_disabled - Whether P2P operations are disabled for this interface
784 * p2p_no_group_iface - Whether group interfaces can be used
786 * By default, wpa_supplicant will create a separate interface for P2P
787 * group operations if the driver supports this. This functionality can

816 * (ECC group defined over a 256-bit prime order field) is preferred,
817 * but other groups are also enabled. If this parameter is set, the
818 * groups will be tried in the indicated order.
823 * dtim_period - Default DTIM period in Beacon intervals
825 * This parameter can be used to set the default value for network
826 * blocks that do not specify dtim_period.
831 * beacon_int - Default Beacon interval in TU
833 * This parameter can be used to set the default value for network
834 * blocks that do not specify beacon_int.
839 * ap_vendor_elements: Vendor specific elements for Beacon/ProbeResp
841 * This parameter can be used to define additional vendor specific
842 * elements for Beacon and Probe Response frames in AP/P2P GO mode. The
843 * format for these element(s) is a hexdump of the raw information
844 * elements (id+len+payload for one or more elements).

849 * ignore_old_scan_res - Ignore scan results older than request
851 * The driver may have a cache of scan results that makes it return
852 * information that is older than our scan trigger. This parameter can
853 * be used to configure such old information to be ignored instead of
854 * allowing it to update the internal BSS table.
