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

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

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

325 * struct wpa_config - wpa_supplicant configuration data
327 * This data structure is presents the per-interface (radio) configuration
328 * data. In many cases, there is only one struct wpa_config instance, but if
329 * more than one network interface is being controlled, one instance is used
334 * ssid - Head of the global network list

338 struct wpa_ssid *ssid;
341 * pssid - Per-priority network lists (in priority order)

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

516 * module is not loaded.
518 char *pkcs11_module_path;
521 * openssl_ciphers - OpenSSL cipher string
523 * This is an OpenSSL specific configuration option for configuring the
524 * default ciphers. If not set, "DEFAULT:!EXP:!LOW" is used as the
527 char *openssl_ciphers;
530 * pcsc_reader - PC/SC reader name prefix
532 * If not %NULL, PC/SC reader with a name that matches this prefix is
533 * initialized for SIM/USIM access. Empty string can be used to match
534 * the first available reader.
539 * pcsc_pin - PIN for USIM, GSM SIM, and smartcards
541 * This field is used to configure PIN for SIM/USIM for EAP-SIM and
542 * EAP-AKA. If left out, this will be asked through control interface.
547 * external_sim - Use external processing for SIM/USIM operations
552 * driver_param - Driver interface parameters
554 * This text string is passed to the selected driver interface with the
555 * optional struct wpa_driver_ops::set_param() handler. This can be
556 * used to configure driver specific options without having to add new
557 * driver interface functionality.

586 * update_config - Is wpa_supplicant allowed to update configuration
588 * This variable control whether wpa_supplicant is allow to re-write
589 * its configuration with wpa_config_write(). If this is zero,
590 * configuration data is only changed in memory and the external data
591 * is not overriden. If this is non-zero, wpa_supplicant will update
592 * the configuration data (e.g., a file) whenever configuration is
593 * changed. This update may replace the old configuration which can

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

916 * matching network block
918 int auto_interworking;
921 * p2p_go_ht40 - Default mode for HT40 enable when operating as GO.
923 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
924 * Note that regulatory constraints and driver capabilities are
925 * consulted anyway, so setting it to 1 can't do real harm.
926 * By default: 0 (disabled)
931 * p2p_go_vht - Default mode for VHT enable when operating as GO
933 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.

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