36 * next - Next credential in the list
38 * This pointer can be used to iterate over all credentials. The head
39 * of this list is stored in the cred field of struct wpa_config.
41 struct wpa_cred *next;
44 * id - Unique id for the credential
46 * This identifier is used as a unique identifier for each credential
47 * block when using the control interface. Each credential is allocated
48 * an id when it is being created, either when reading the
49 * configuration file or when a new credential is added through the
55 * priority - Priority group
57 * By default, all networks and credentials get the same priority group
58 * (0). This field can be used to give higher priority for credentials
59 * (and similarly in struct wpa_ssid for network blocks) to change the
60 * Interworking automatic networking selection behavior. The matching
61 * network (based on either an enabled network block or a credential)
62 * with the highest priority value will be selected.
67 * pcsc - Use PC/SC and SIM/USIM card
72 * realm - Home Realm for Interworking
77 * username - Username for Interworking network selection
82 * password - Password for Interworking network selection
87 * ext_password - Whether password is a name for external storage
92 * ca_cert - CA certificate for Interworking network selection
97 * client_cert - File path to client certificate file (PEM/DER)
99 * This field is used with Interworking networking selection for a case
100 * where client certificate/private key is used for authentication
101 * (EAP-TLS). Full path to the file should be used since working
102 * directory may change when wpa_supplicant is run in the background.
104 * Alternatively, a named configuration blob can be used by setting
105 * this to blob://blob_name.
110 * private_key - File path to client private key file (PEM/DER/PFX)
112 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
113 * commented out. Both the private key and certificate will be read
114 * from the PKCS#12 file in this case. Full path to the file should be
115 * used since working directory may change when wpa_supplicant is run
118 * Windows certificate store can be used by leaving client_cert out and
119 * configuring private_key in one of the following formats:
121 * cert://substring_to_match
123 * hash://certificate_thumbprint_in_hex
125 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
127 * Note that when running wpa_supplicant as an application, the user
128 * certificate store (My user account) is used, whereas computer store
129 * (Computer account) is used when running wpasvc as a service.
131 * Alternatively, a named configuration blob can be used by setting
132 * this to blob://blob_name.
137 * private_key_passwd - Password for private key file
139 char *private_key_passwd;
142 * imsi - IMSI in <MCC> | <MNC> | '-' | <MSIN> format
147 * milenage - Milenage parameters for SIM/USIM simulator in
148 * <Ki>:<OPc>:<SQN> format
153 * domain_suffix_match - Constraint for server domain name
155 * If set, this FQDN is used as a suffix match requirement for the AAA
156 * server certificate in SubjectAltName dNSName element(s). If a
157 * matching dNSName is found, this constraint is met. If no dNSName
158 * values are present, this constraint is matched against SubjetName CN
159 * using same suffix match comparison. Suffix match here means that the
160 * host/domain name is compared one label at a time starting from the
161 * top-level domain and all the labels in @domain_suffix_match shall be
162 * included in the certificate. The certificate may include additional
163 * sub-level labels in addition to the required labels.
165 * For example, domain_suffix_match=example.com would match
166 * test.example.com but would not match test-example.com.
168 char *domain_suffix_match;
171 * domain - Home service provider FQDN(s)
173 * This is used to compare against the Domain Name List to figure out
174 * whether the AP is operated by the Home SP. Multiple domain entries
175 * can be used to configure alternative FQDNs that will be considered
181 * num_domain - Number of FQDNs in the domain array
186 * roaming_consortium - Roaming Consortium OI
188 * If roaming_consortium_len is non-zero, this field contains the
189 * Roaming Consortium OI that can be used to determine which access
190 * points support authentication with this credential. This is an
191 * alternative to the use of the realm parameter. When using Roaming
192 * Consortium to match the network, the EAP parameters need to be
193 * pre-configured with the credential since the NAI Realm information
194 * may not be available or fetched.

255 * struct wpa_config - wpa_supplicant configuration data
257 * This data structure is presents the per-interface (radio) configuration
258 * data. In many cases, there is only one struct wpa_config instance, but if
259 * more than one network interface is being controlled, one instance is used
264 * ssid - Head of the global network list
266 * This is the head for the list of all the configured networks.

271 * pssid - Per-priority network lists (in priority order)
273 struct wpa_ssid **pssid;
276 * num_prio - Number of different priorities used in the pssid lists
278 * This indicates how many per-priority network lists are included in
284 * cred - Head of the credential list
286 * This is the head for the list of all the configured credentials.
288 struct wpa_cred *cred;
291 * eapol_version - IEEE 802.1X/EAPOL version number
293 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
294 * defines EAPOL version 2. However, there are many APs that do not
295 * handle the new version number correctly (they seem to drop the
296 * frames completely). In order to make wpa_supplicant interoperate
297 * with these APs, the version number is set to 1 by default. This
298 * configuration value can be used to set it to the new version (2).
303 * ap_scan - AP scanning/selection
305 * By default, wpa_supplicant requests driver to perform AP
306 * scanning and then uses the scan results to select a
307 * suitable AP. Another alternative is to allow the driver to
308 * take care of AP scanning and selection and use
309 * wpa_supplicant just to process EAPOL frames based on IEEE
310 * 802.11 association information from the driver.
312 * 1: wpa_supplicant initiates scanning and AP selection (default).
314 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
315 * association parameters (e.g., WPA IE generation); this mode can
316 * also be used with non-WPA drivers when using IEEE 802.1X mode;
317 * do not try to associate with APs (i.e., external program needs
318 * to control association). This mode must also be used when using
319 * wired Ethernet drivers.
321 * 2: like 0, but associate with APs using security policy and SSID
322 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
323 * drivers to enable operation with hidden SSIDs and optimized roaming;
324 * in this mode, the network blocks in the configuration are tried
325 * one by one until the driver reports successful association; each
326 * network block should have explicit security policy (i.e., only one
327 * option in the lists) for key_mgmt, pairwise, group, proto variables.
332 * bgscan - Background scan and roaming parameters or %NULL if none
334 * This is an optional set of parameters for background scanning and
335 * roaming within a network (ESS). For more detailed information see
336 * ssid block documentation.
338 * The variable defines default bgscan behavior for all BSS station
339 * networks except for those which have their own bgscan configuration.
344 * disable_scan_offload - Disable automatic offloading of scan requests
346 * By default, %wpa_supplicant tries to offload scanning if the driver
347 * indicates support for this (sched_scan). This configuration
348 * parameter can be used to disable this offloading mechanism.
350 int disable_scan_offload;
353 * ctrl_interface - Parameters for the control interface
355 * If this is specified, %wpa_supplicant will open a control interface
356 * that is available for external programs to manage %wpa_supplicant.
357 * The meaning of this string depends on which control interface
358 * mechanism is used. For all cases, the existence of this parameter
359 * in configuration is used to determine whether the control interface
362 * For UNIX domain sockets (default on Linux and BSD): This is a
363 * directory that will be created for UNIX domain sockets for listening
364 * to requests from external programs (CLI/GUI, etc.) for status
365 * information and configuration. The socket file will be named based
366 * on the interface name, so multiple %wpa_supplicant processes can be
367 * run at the same time if more than one interface is used.
368 * /var/run/wpa_supplicant is the recommended directory for sockets and
369 * by default, wpa_cli will use it when trying to connect with
372 * Access control for the control interface can be configured
373 * by setting the directory to allow only members of a group
374 * to use sockets. This way, it is possible to run
375 * %wpa_supplicant as root (since it needs to change network
376 * configuration and open raw sockets) and still allow GUI/CLI
377 * components to be run as non-root users. However, since the
378 * control interface can be used to change the network
379 * configuration, this access needs to be protected in many
380 * cases. By default, %wpa_supplicant is configured to use gid
381 * 0 (root). If you want to allow non-root users to use the
382 * control interface, add a new group and change this value to
383 * match with that group. Add users that should have control
384 * interface access to this group.
386 * When configuring both the directory and group, use following format:
387 * DIR=/var/run/wpa_supplicant GROUP=wheel
388 * DIR=/var/run/wpa_supplicant GROUP=0
389 * (group can be either group name or gid)
391 * For UDP connections (default on Windows): The value will be ignored.
392 * This variable is just used to select that the control interface is
393 * to be created. The value can be set to, e.g., udp
394 * (ctrl_interface=udp).
396 * For Windows Named Pipe: This value can be used to set the security
397 * descriptor for controlling access to the control interface. Security
398 * descriptor can be set using Security Descriptor String Format (see
399 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
400 * The descriptor string needs to be prefixed with SDDL=. For example,
401 * ctrl_interface=SDDL=D: would set an empty DACL (which will reject
404 char *ctrl_interface;
407 * ctrl_interface_group - Control interface group (DEPRECATED)
409 * This variable is only used for backwards compatibility. Group for
410 * UNIX domain sockets should now be specified using GROUP=group in
411 * ctrl_interface variable.
413 char *ctrl_interface_group;
416 * fast_reauth - EAP fast re-authentication (session resumption)
418 * By default, fast re-authentication is enabled for all EAP methods
419 * that support it. This variable can be used to disable fast
420 * re-authentication (by setting fast_reauth=0). Normally, there is no
421 * need to disable fast re-authentication.
426 * opensc_engine_path - Path to the OpenSSL engine for opensc
428 * This is an OpenSSL specific configuration option for loading OpenSC
429 * engine (engine_opensc.so); if %NULL, this engine is not loaded.
431 char *opensc_engine_path;
434 * pkcs11_engine_path - Path to the OpenSSL engine for PKCS#11

444 * This is an OpenSSL specific configuration option for configuring
445 * path to OpenSC/PKCS#11 engine (opensc-pkcs11.so); if %NULL, this
446 * module is not loaded.
448 char *pkcs11_module_path;
451 * pcsc_reader - PC/SC reader name prefix
453 * If not %NULL, PC/SC reader with a name that matches this prefix is
454 * initialized for SIM/USIM access. Empty string can be used to match
455 * the first available reader.
460 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
462 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
463 * EAP-AKA. If left out, this will be asked through control interface.
468 * external_sim - Use external processing for SIM/USIM operations
473 * driver_param - Driver interface parameters
475 * This text string is passed to the selected driver interface with the
476 * optional struct wpa_driver_ops::set_param() handler. This can be
477 * used to configure driver specific options without having to add new
478 * driver interface functionality.
483 * dot11RSNAConfigPMKLifetime - Maximum lifetime of a PMK
485 * dot11 MIB variable for the maximum lifetime of a PMK in the PMK
486 * cache (unit: seconds).

501 * dot11 MIB variable for the maximum time a security association
502 * shall take to set up (unit: seconds).

507 * update_config - Is wpa_supplicant allowed to update configuration
509 * This variable control whether wpa_supplicant is allow to re-write
510 * its configuration with wpa_config_write(). If this is zero,
511 * configuration data is only changed in memory and the external data
512 * is not overriden. If this is non-zero, wpa_supplicant will update
513 * the configuration data (e.g., a file) whenever configuration is
514 * changed. This update may replace the old configuration which can
515 * remove comments from it in case of a text file configuration.

633 * p2p_group_idle - Maximum idle time in seconds for P2P group
635 * This value controls how long a P2P group is maintained after there
636 * is no other members in the group. As a GO, this means no associated
637 * stations in the group. As a P2P client, this means no GO seen in
638 * scan results. The maximum idle time is specified in seconds with 0
639 * indicating no time limit, i.e., the P2P group remains in active
640 * state indefinitely until explicitly removed. As a P2P client, the
641 * maximum idle time of P2P_MAX_CLIENT_IDLE seconds is enforced, i.e.,
642 * this parameter is mainly meant for GO use and for P2P client, it can
643 * only be used to reduce the default timeout to smaller value. A

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

729 * When Interworking is enabled, scans will be limited to APs that
730 * advertise the specified Access Network Type (0..15; with 15
731 * indicating wildcard match).
733 int access_network_type;

740 * Homogeneous ESS. This is used only if interworking is enabled.
750 * pbc_in_m1 - AP mode WPS probing workaround for PBC with Windows 7
752 * Windows 7 uses incorrect way of figuring out AP's WPS capabilities
753 * by acting as a Registrar and using M1 from the AP. The config
754 * methods attribute in that message is supposed to indicate only the
755 * configuration method supported by the AP in Enrollee role, i.e., to

824 * 0 = do not automatically go through Interworking network selection
825 * (i.e., require explicit interworking_select command for this)
826 * 1 = perform Interworking network selection if one or more
827 * credentials have been configured and scan did not find a
828 * matching network block
830 int auto_interworking;
833 * p2p_go_ht40 - Default mode for HT40 enable when operating as GO.
835 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
836 * Note that regulatory constraints and driver capabilities are
837 * consulted anyway, so setting it to 1 can't do real harm.
838 * By default: 0 (disabled)
843 * p2p_go_vht - Default mode for VHT enable when operating as GO
845 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
846 * Note that regulatory constraints and driver capabilities are
847 * consulted anyway, so setting it to 1 can't do real harm.

853 * p2p_disabled - Whether P2P operations are disabled for this interface
858 * p2p_no_group_iface - Whether group interfaces can be used
860 * By default, wpa_supplicant will create a separate interface for P2P
861 * group operations if the driver supports this. This functionality can
862 * be disabled by setting this parameter to 1. In that case, the same
863 * interface that was used for the P2P management operations is used
864 * also for the group operation.

869 * okc - Whether to enable opportunistic key caching by default
871 * By default, OKC is disabled unless enabled by the per-network
872 * proactive_key_caching=1 parameter. okc=1 can be used to change this
878 * pmf - Whether to enable/require PMF by default
880 * By default, PMF is disabled unless enabled by the per-network
881 * ieee80211w=1 or ieee80211w=2 parameter. pmf=1/2 can be used to change
882 * this default behavior.
884 enum mfp_options pmf;
887 * sae_groups - Preference list of enabled groups for SAE
889 * By default (if this parameter is not set), the mandatory group 19
890 * (ECC group defined over a 256-bit prime order field) is preferred,
891 * but other groups are also enabled. If this parameter is set, the
892 * groups will be tried in the indicated order.
897 * dtim_period - Default DTIM period in Beacon intervals
899 * This parameter can be used to set the default value for network
900 * blocks that do not specify dtim_period.
905 * beacon_int - Default Beacon interval in TU
907 * This parameter can be used to set the default value for network
908 * blocks that do not specify beacon_int.
913 * ap_vendor_elements: Vendor specific elements for Beacon/ProbeResp
915 * This parameter can be used to define additional vendor specific
916 * elements for Beacon and Probe Response frames in AP/P2P GO mode. The
917 * format for these element(s) is a hexdump of the raw information
918 * elements (id+len+payload for one or more elements).
920 struct wpabuf *ap_vendor_elements;
923 * ignore_old_scan_res - Ignore scan results older than request
925 * The driver may have a cache of scan results that makes it return
926 * information that is older than our scan trigger. This parameter can
927 * be used to configure such old information to be ignored instead of
928 * allowing it to update the internal BSS table.
930 int ignore_old_scan_res;
933 * sched_scan_interval - schedule scan interval
935 unsigned int sched_scan_interval;
938 * tdls_external_control - External control for TDLS setup requests
940 * Enable TDLS mode where external programs are given the control
941 * to specify the TDLS link to get established to the driver. The
942 * driver requests the TDLS setup to the supplicant only for the
943 * specified TDLS peers.
