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 * temporary - Whether this credential is temporary and not to be saved
60 * priority - Priority group
62 * By default, all networks and credentials get the same priority group
63 * (0). This field can be used to give higher priority for credentials
64 * (and similarly in struct wpa_ssid for network blocks) to change the
65 * Interworking automatic networking selection behavior. The matching
66 * network (based on either an enabled network block or a credential)
67 * with the highest priority value will be selected.
72 * pcsc - Use PC/SC and SIM/USIM card
77 * realm - Home Realm for Interworking
82 * username - Username for Interworking network selection
87 * password - Password for Interworking network selection
92 * ext_password - Whether password is a name for external storage
97 * ca_cert - CA certificate for Interworking network selection
102 * client_cert - File path to client certificate file (PEM/DER)
104 * This field is used with Interworking networking selection for a case
105 * where client certificate/private key is used for authentication
106 * (EAP-TLS). Full path to the file should be used since working
107 * directory may change when wpa_supplicant is run in the background.
109 * Alternatively, a named configuration blob can be used by setting
110 * this to blob://blob_name.
115 * private_key - File path to client private key file (PEM/DER/PFX)
117 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
118 * commented out. Both the private key and certificate will be read
119 * from the PKCS#12 file in this case. Full path to the file should be
120 * used since working directory may change when wpa_supplicant is run
123 * Windows certificate store can be used by leaving client_cert out and
124 * configuring private_key in one of the following formats:
126 * cert://substring_to_match
128 * hash://certificate_thumbprint_in_hex
130 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
132 * Note that when running wpa_supplicant as an application, the user
133 * certificate store (My user account) is used, whereas computer store
134 * (Computer account) is used when running wpasvc as a service.
136 * Alternatively, a named configuration blob can be used by setting
137 * this to blob://blob_name.
142 * private_key_passwd - Password for private key file
144 char *private_key_passwd;
147 * imsi - IMSI in <MCC> | <MNC> | '-' | <MSIN> format
152 * milenage - Milenage parameters for SIM/USIM simulator in
153 * <Ki>:<OPc>:<SQN> format
158 * domain_suffix_match - Constraint for server domain name
160 * If set, this FQDN is used as a suffix match requirement for the AAA
161 * server certificate in SubjectAltName dNSName element(s). If a
162 * matching dNSName is found, this constraint is met. If no dNSName
163 * values are present, this constraint is matched against SubjetName CN
164 * using same suffix match comparison. Suffix match here means that the
165 * host/domain name is compared one label at a time starting from the
166 * top-level domain and all the labels in @domain_suffix_match shall be
167 * included in the certificate. The certificate may include additional
168 * sub-level labels in addition to the required labels.
170 * For example, domain_suffix_match=example.com would match
171 * test.example.com but would not match test-example.com.
173 char *domain_suffix_match;
176 * domain - Home service provider FQDN(s)
178 * This is used to compare against the Domain Name List to figure out
179 * whether the AP is operated by the Home SP. Multiple domain entries
180 * can be used to configure alternative FQDNs that will be considered
186 * num_domain - Number of FQDNs in the domain array

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

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

511 * module is not loaded.
513 char *pkcs11_module_path;
516 * pcsc_reader - PC/SC reader name prefix
518 * If not %NULL, PC/SC reader with a name that matches this prefix is
519 * initialized for SIM/USIM access. Empty string can be used to match
520 * the first available reader.
525 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
527 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
528 * EAP-AKA. If left out, this will be asked through control interface.
533 * external_sim - Use external processing for SIM/USIM operations
538 * driver_param - Driver interface parameters
540 * This text string is passed to the selected driver interface with the
541 * optional struct wpa_driver_ops::set_param() handler. This can be
542 * used to configure driver specific options without having to add new
543 * driver interface functionality.

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

823 * If pbc_in_m1=1 is included in the configuration file, the PushButton
824 * config method is left in M1 (if included in config_methods

893 * matching network block
895 int auto_interworking;
898 * p2p_go_ht40 - Default mode for HT40 enable when operating as GO.
900 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
901 * Note that regulatory constraints and driver capabilities are
902 * consulted anyway, so setting it to 1 can't do real harm.
903 * By default: 0 (disabled)

918 * p2p_disabled - Whether P2P operations are disabled for this interface
923 * p2p_no_group_iface - Whether group interfaces can be used
925 * By default, wpa_supplicant will create a separate interface for P2P
926 * group operations if the driver supports this. This functionality can
927 * be disabled by setting this parameter to 1. In that case, the same
928 * interface that was used for the P2P management operations is used
929 * also for the group operation.

956 * but other groups are also enabled. If this parameter is set, the
957 * groups will be tried in the indicated order.
962 * dtim_period - Default DTIM period in Beacon intervals
964 * This parameter can be used to set the default value for network
965 * blocks that do not specify dtim_period.
970 * beacon_int - Default Beacon interval in TU
972 * This parameter can be used to set the default value for network
973 * blocks that do not specify beacon_int.
978 * ap_vendor_elements: Vendor specific elements for Beacon/ProbeResp
980 * This parameter can be used to define additional vendor specific
981 * elements for Beacon and Probe Response frames in AP/P2P GO mode. The
982 * format for these element(s) is a hexdump of the raw information
983 * elements (id+len+payload for one or more elements).
985 struct wpabuf *ap_vendor_elements;
988 * ignore_old_scan_res - Ignore scan results older than request
990 * The driver may have a cache of scan results that makes it return
991 * information that is older than our scan trigger. This parameter can
992 * be used to configure such old information to be ignored instead of
993 * allowing it to update the internal BSS table.
995 int ignore_old_scan_res;
998 * sched_scan_interval - schedule scan interval
1000 unsigned int sched_scan_interval;
1003 * tdls_external_control - External control for TDLS setup requests
1005 * Enable TDLS mode where external programs are given the control
1006 * to specify the TDLS link to get established to the driver. The
1007 * driver requests the TDLS setup to the supplicant only for the
1008 * specified TDLS peers.
