59 * next - Next credential in the list
61 * This pointer can be used to iterate over all credentials. The head
62 * of this list is stored in the cred field of struct wpa_config.
64 struct wpa_cred

;
67 * id - Unique id for the credential
69 * This identifier is used as a unique identifier for each credential
70 * block when using the control interface. Each credential is allocated
71 * an id when it is being created, either when reading the
72 * configuration file or when a new credential is added through the
78 * temporary - Whether this credential is temporary and not to be saved
83 * priority - Priority group
85 * By default, all networks and credentials get the same priority group
86 * (0). This field can be used to give higher priority for credentials
87 * (and similarly in struct wpa_ssid for network blocks) to change the
88 * Interworking automatic networking selection behavior. The matching
89 * network (based on either an enabled network block or a credential)
90 * with the highest priority value will be selected.
95 * pcsc - Use PC/SC and SIM/USIM card
100 * realm - Home Realm for Interworking
105 * username - Username for Interworking network selection
110 * password - Password for Interworking network selection
115 * ext_password - Whether password is a name for external storage
120 * ca_cert - CA certificate for Interworking network selection
125 * client_cert - File path to client certificate file (PEM/DER)
127 * This field is used with Interworking networking selection for a case
128 * where client certificate/private key is used for authentication
129 * (EAP-TLS). Full path to the file should be used since working
130 * directory may change when wpa_supplicant is run in the background.
132 * Alternatively, a named configuration blob can be used by setting
133 * this to blob://blob_name.
138 * private_key - File path to client private key file (PEM/DER/PFX)
140 * When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
141 * commented out. Both the private key and certificate will be read
142 * from the PKCS#12 file in this case. Full path to the file should be
143 * used since working directory may change when wpa_supplicant is run
146 * Windows certificate store can be used by leaving client_cert out and
147 * configuring private_key in one of the following formats:
149 * cert://substring_to_match
151 * hash://certificate_thumbprint_in_hex
153 * For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
155 * Note that when running wpa_supplicant as an application, the user
156 * certificate store (My user account) is used, whereas computer store
157 * (Computer account) is used when running wpasvc as a service.
159 * Alternatively, a named configuration blob can be used by setting
160 * this to blob://blob_name.

181 * domain_suffix_match - Constraint for server domain name
183 * If set, this FQDN is used as a suffix match requirement for the AAA
184 * server certificate in SubjectAltName dNSName element(s). If a
185 * matching dNSName is found, this constraint is met. If no dNSName
186 * values are present, this constraint is matched against SubjectName CN
187 * using same suffix match comparison. Suffix match here means that the
188 * host/domain name is compared one label at a time starting from the
189 * top-level domain and all the labels in @domain_suffix_match shall be
190 * included in the certificate. The certificate may include additional
191 * sub-level labels in addition to the required labels.
193 * For example, domain_suffix_match=example.com would match
194 * test.example.com but would not match test-example.com.

416 * eapol_version - IEEE 802.1X/EAPOL version number
418 * wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which
419 * defines EAPOL version 2. However, there are many APs that do not
420 * handle the new version number correctly (they seem to drop the
421 * frames completely). In order to make wpa_supplicant interoperate
422 * with these APs, the version number is set to 1 by default. This
423 * configuration value can be used to set it to the new version (2).
428 * ap_scan - AP scanning/selection
430 * By default, wpa_supplicant requests driver to perform AP
431 * scanning and then uses the scan results to select a
432 * suitable AP. Another alternative is to allow the driver to
433 * take care of AP scanning and selection and use
434 * wpa_supplicant just to process EAPOL frames based on IEEE
435 * 802.11 association information from the driver.
437 * 1: wpa_supplicant initiates scanning and AP selection (default).
439 * 0: Driver takes care of scanning, AP selection, and IEEE 802.11
440 * association parameters (e.g., WPA IE generation); this mode can
441 * also be used with non-WPA drivers when using IEEE 802.1X mode;
442 * do not try to associate with APs (i.e., external program needs
443 * to control association). This mode must also be used when using
444 * wired Ethernet drivers.
446 * 2: like 0, but associate with APs using security policy and SSID
447 * (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS
448 * drivers to enable operation with hidden SSIDs and optimized roaming;
449 * in this mode, the network blocks in the configuration are tried
450 * one by one until the driver reports successful association; each
451 * network block should have explicit security policy (i.e., only one
452 * option in the lists) for key_mgmt, pairwise, group, proto variables.
454 * Note: ap_scan=2 should not be used with the nl80211 driver interface
455 * (the current Linux interface). ap_scan=1 is optimized work working
456 * with nl80211. For finding networks using hidden SSID, scan_ssid=1 in
457 * the network block can be used with nl80211.
462 * bgscan - Background scan and roaming parameters or %NULL if none
464 * This is an optional set of parameters for background scanning and
465 * roaming within a network (ESS). For more detailed information see
466 * ssid block documentation.
468 * The variable defines default bgscan behavior for all BSS station
469 * networks except for those which have their own bgscan configuration.
474 * disable_scan_offload - Disable automatic offloading of scan requests
476 * By default, %wpa_supplicant tries to offload scanning if the driver
477 * indicates support for this (sched_scan). This configuration
478 * parameter can be used to disable this offloading mechanism.
480 int disable_scan_offload
;
483 * ctrl_interface - Parameters for the control interface
485 * If this is specified, %wpa_supplicant will open a control interface
486 * that is available for external programs to manage %wpa_supplicant.
487 * The meaning of this string depends on which control interface
488 * mechanism is used. For all cases, the existence of this parameter
489 * in configuration is used to determine whether the control interface
492 * For UNIX domain sockets (default on Linux and BSD): This is a
493 * directory that will be created for UNIX domain sockets for listening
494 * to requests from external programs (CLI/GUI, etc.) for status
495 * information and configuration. The socket file will be named based
496 * on the interface name, so multiple %wpa_supplicant processes can be
497 * run at the same time if more than one interface is used.
498 * /var/run/wpa_supplicant is the recommended directory for sockets and
499 * by default, wpa_cli will use it when trying to connect with
502 * Access control for the control interface can be configured
503 * by setting the directory to allow only members of a group
504 * to use sockets. This way, it is possible to run
505 * %wpa_supplicant as root (since it needs to change network
506 * configuration and open raw sockets) and still allow GUI/CLI
507 * components to be run as non-root users. However, since the
508 * control interface can be used to change the network
509 * configuration, this access needs to be protected in many
510 * cases. By default, %wpa_supplicant is configured to use gid
511 * 0 (root). If you want to allow non-root users to use the
512 * control interface, add a new group and change this value to
513 * match with that group. Add users that should have control
514 * interface access to this group.
516 * When configuring both the directory and group, use following format:
517 * DIR=/var/run/wpa_supplicant GROUP=wheel
518 * DIR=/var/run/wpa_supplicant GROUP=0
519 * (group can be either group name or gid)
521 * For UDP connections (default on Windows): The value will be ignored.
522 * This variable is just used to select that the control interface is
523 * to be created. The value can be set to, e.g., udp
524 * (ctrl_interface=udp).
526 * For Windows Named Pipe: This value can be used to set the security
527 * descriptor for controlling access to the control interface. Security
528 * descriptor can be set using Security Descriptor String Format (see
529 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
530 * The descriptor string needs to be prefixed with SDDL=. For example,

546 * fast_reauth - EAP fast re-authentication (session resumption)
548 * By default, fast re-authentication is enabled for all EAP methods
