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

153 char *private_key_passwd;
156 * imsi - IMSI in <MCC> | <MNC> | '-' | <MSIN> format
161 * milenage - Milenage parameters for SIM/USIM simulator in
162 * <Ki>:<OPc>:<SQN> format
167 * domain_suffix_match - Constraint for server domain name
169 * If set, this FQDN is used as a suffix match requirement for the AAA
170 * server certificate in SubjectAltName dNSName element(s). If a
171 * matching dNSName is found, this constraint is met. If no dNSName
172 * values are present, this constraint is matched against SubjectName CN
173 * using same suffix match comparison. Suffix match here means that the
174 * host/domain name is compared one label at a time starting from the
175 * top-level domain and all the labels in @domain_suffix_match shall be
176 * included in the certificate. The certificate may include additional
177 * sub-level labels in addition to the required labels.
179 * For example, domain_suffix_match=example.com would match
180 * test.example.com but would not match test-example.com.
182 char *domain_suffix_match;
185 * domain - Home service provider FQDN(s)
187 * This is used to compare against the Domain Name List to figure out
188 * whether the AP is operated by the Home SP. Multiple domain entries
189 * can be used to configure alternative FQDNs that will be considered
195 * num_domain - Number of FQDNs in the domain array
200 * roaming_consortium - Roaming Consortium OI
202 * If roaming_consortium_len is non-zero, this field contains the
203 * Roaming Consortium OI that can be used to determine which access
204 * points support authentication with this credential. This is an
205 * alternative to the use of the realm parameter. When using Roaming
206 * Consortium to match the network, the EAP parameters need to be
207 * pre-configured with the credential since the NAI Realm information
208 * may not be available or fetched.

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

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

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

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

928 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
929 * Note that regulatory constraints and driver capabilities are
930 * consulted anyway, so setting it to 1 can't do real harm.
931 * By default: 0 (disabled)
936 * p2p_go_vht - Default mode for VHT enable when operating as GO
938 * This will take effect for p2p_group_add, p2p_connect, and p2p_invite.
939 * Note that regulatory constraints and driver capabilities are
940 * consulted anyway, so setting it to 1 can't do real harm.
941 * By default: 0 (disabled)
946 * p2p_go_ctwindow - CTWindow to use when operating as GO

981 * By default, PMF is disabled unless enabled by the per-network
982 * ieee80211w=1 or ieee80211w=2 parameter. pmf=1/2 can be used to change
983 * this default behavior.
985 enum mfp_options pmf;
988 * sae_groups - Preference list of enabled groups for SAE
990 * By default (if this parameter is not set), the mandatory group 19
991 * (ECC group defined over a 256-bit prime order field) is preferred,
992 * but other groups are also enabled. If this parameter is set, the
993 * groups will be tried in the indicated order.

1024 * ignore_old_scan_res - Ignore scan results older than request
1026 * The driver may have a cache of scan results that makes it return
1027 * information that is older than our scan trigger. This parameter can

1034 * sched_scan_interval - schedule scan interval
1036 unsigned int sched_scan_interval;
1039 * tdls_external_control - External control for TDLS setup requests
1041 * Enable TDLS mode where external programs are given the control

1050 u8 ip_addr_start[4];
1054 * osu_dir - OSU provider information directory
1056 * If set, allow FETCH_OSU control interface command to be used to fetch
1057 * OSU provider information into all APs and store the results in this
1063 * wowlan_triggers - Wake-on-WLAN triggers
1065 * If set, these wowlan triggers will be configured.

1146 * By default: 300 seconds.
1148 int mesh_max_inactivity;
1151 * passive_scan - Whether to force passive scan for network connection
1153 * This parameter can be used to force only passive scanning to be used
1154 * for network connection cases. It should be noted that this will slow
1155 * down scan operations and reduce likelihood of finding the AP. In
1156 * addition, some use cases will override this due to functional
1157 * requirements, e.g., for finding an AP that uses hidden SSID
1158 * (scan_ssid=1) or P2P device discovery.
