Detailed Description

struct wpa_config - wpa_supplicant configuration data

This data structure is presents the per-interface (radio) configuration data. In many cases, there is only one struct wpa_config instance, but if more than one network interface is being controlled, one instance is used for each.

Member Enumeration Documentation

§ anonymous enum

anonymous enum

p2p_go_freq_change_policy - The GO frequency change policy

This controls the behavior of the GO when there is a change in the map of the currently used frequencies in case more than one channel is supported.

: Prefer working in a single channel mode if possible. In case the GO is the only interface using its frequency and there are other station interfaces on other frequencies, the GO will migrate to one of these frequencies.

: Same as P2P_GO_FREQ_MOVE_SCM, but a transition is possible only in case one of the other used frequencies is one of the frequencies in the intersection of the frequency list of the local device and the peer device.

: Prefer to stay on the current frequency.

: Same as P2P_GO_FREQ_MOVE_SCM_PEER_SUPPORTS but a transition is possible only if all the group members advertise eCSA support.

Member Data Documentation

§ access_network_type

int wpa_config::access_network_type

access_network_type - Access Network Type

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

§ ap_scan

int wpa_config::ap_scan

ap_scan - AP scanning/selection

By default, wpa_supplicant requests driver to perform AP scanning and then uses the scan results to select a suitable AP. Another alternative is to allow the driver to take care of AP scanning and selection and use wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association information from the driver.

1: wpa_supplicant initiates scanning and AP selection (default).

0: Driver takes care of scanning, AP selection, and IEEE 802.11 association parameters (e.g., WPA IE generation); this mode can also be used with non-WPA drivers when using IEEE 802.1X mode; do not try to associate with APs (i.e., external program needs to control association). This mode must also be used when using wired Ethernet drivers.

2: like 0, but associate with APs using security policy and SSID (but not BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to enable operation with hidden SSIDs and optimized roaming; in this mode, the network blocks in the configuration are tried one by one until the driver reports successful association; each network block should have explicit security policy (i.e., only one option in the lists) for key_mgmt, pairwise, group, proto variables.

Note: ap_scan=2 should not be used with the nl80211 driver interface (the current Linux interface). ap_scan=1 is optimized work working with nl80211. For finding networks using hidden SSID, scan_ssid=1 in the network block can be used with nl80211.

§ ap_vendor_elements

struct wpabuf* wpa_config::ap_vendor_elements

ap_vendor_elements: Vendor specific elements for Beacon/ProbeResp

This parameter can be used to define additional vendor specific elements for Beacon and Probe Response frames in AP/P2P GO mode. The format for these element(s) is a hexdump of the raw information elements (id+len+payload for one or more elements).

§ auto_interworking

int wpa_config::auto_interworking

auto_interworking - Whether to use network selection automatically

0 = do not automatically go through Interworking network selection (i.e., require explicit interworking_select command for this) 1 = perform Interworking network selection if one or more credentials have been configured and scan did not find a matching network block

§ autoscan

char* wpa_config::autoscan

autoscan - Automatic scan parameters or NULL if none

This is an optional set of parameters for automatic scanning within an interface in following format: <autoscan module="" name>="">:<module parameters>="">

§ beacon_int

int wpa_config::beacon_int

beacon_int - Default Beacon interval in TU

This parameter can be used to set the default value for network blocks that do not specify beacon_int.

§ bgscan

char* wpa_config::bgscan

bgscan - Background scan and roaming parameters or NULL if none

This is an optional set of parameters for background scanning and roaming within a network (ESS). For more detailed information see ssid block documentation.

The variable defines default bgscan behavior for all BSS station networks except for those which have their own bgscan configuration.

§ bss_expiration_age

unsigned int wpa_config::bss_expiration_age

bss_expiration_age - BSS entry age after which it can be expired

This value controls the time in seconds after which a BSS entry gets removed if it has not been updated or is not in use.

§ bss_expiration_scan_count

unsigned int wpa_config::bss_expiration_scan_count

bss_expiration_scan_count - Expire BSS after number of scans

If the BSS entry has not been seen in this many scans, it will be removed. A value of 1 means that entry is removed after the first scan in which the BSSID is not seen. Larger values can be used to avoid BSS entries disappearing if they are not visible in every scan (e.g., low signal quality or interference).

§ cert_in_cb

int wpa_config::cert_in_cb

cert_in_cb - Whether to include a peer certificate dump in events

This controls whether peer certificates for authentication server and its certificate chain are included in EAP peer certificate events.

§ config_methods

char* wpa_config::config_methods

config_methods - Config Methods

This is a space-separated list of supported WPS configuration methods. For example, "label virtual_display virtual_push_button keypad". Available methods: usba ethernet label display ext_nfc_token int_nfc_token nfc_interface push_button keypad virtual_display physical_display virtual_push_button physical_push_button.

§ country

char wpa_config::country[2]

country - Country code

This is the ISO/IEC alpha2 country code for which we are operating in

§ cred

struct wpa_cred* wpa_config::cred

cred - Head of the credential list

This is the head for the list of all the configured credentials.

§ ctrl_interface

char* wpa_config::ctrl_interface

ctrl_interface - Parameters for the control interface

If this is specified, wpa_supplicant will open a control interface that is available for external programs to manage wpa_supplicant. The meaning of this string depends on which control interface mechanism is used. For all cases, the existence of this parameter in configuration is used to determine whether the control interface is enabled.

For UNIX domain sockets (default on Linux and BSD): This is a directory that will be created for UNIX domain sockets for listening to requests from external programs (CLI/GUI, etc.) for status information and configuration. The socket file will be named based on the interface name, so multiple wpa_supplicant processes can be run at the same time if more than one interface is used. /var/run/wpa_supplicant is the recommended directory for sockets and by default, wpa_cli will use it when trying to connect with wpa_supplicant.

Access control for the control interface can be configured by setting the directory to allow only members of a group to use sockets. This way, it is possible to run wpa_supplicant as root (since it needs to change network configuration and open raw sockets) and still allow GUI/CLI components to be run as non-root users. However, since the control interface can be used to change the network configuration, this access needs to be protected in many cases. By default, wpa_supplicant is configured to use gid 0 (root). If you want to allow non-root users to use the control interface, add a new group and change this value to match with that group. Add users that should have control interface access to this group.

When configuring both the directory and group, use following format: DIR=/var/run/wpa_supplicant GROUP=wheel DIR=/var/run/wpa_supplicant GROUP=0 (group can be either group name or gid)

For UDP connections (default on Windows): The value will be ignored. This variable is just used to select that the control interface is to be created. The value can be set to, e.g., udp (ctrl_interface=udp).

For Windows Named Pipe: This value can be used to set the security descriptor for controlling access to the control interface. Security descriptor can be set using Security Descriptor String Format (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp). The descriptor string needs to be prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty DACL (which will reject all connections).

§ ctrl_interface_group

char* wpa_config::ctrl_interface_group

ctrl_interface_group - Control interface group (DEPRECATED)

This variable is only used for backwards compatibility. Group for UNIX domain sockets should now be specified using GROUP=group in ctrl_interface variable.

§ disable_scan_offload

int wpa_config::disable_scan_offload

disable_scan_offload - Disable automatic offloading of scan requests

By default, wpa_supplicant tries to offload scanning if the driver indicates support for this (sched_scan). This configuration parameter can be used to disable this offloading mechanism.

§ dot11RSNAConfigPMKLifetime

unsigned int wpa_config::dot11RSNAConfigPMKLifetime

dot11RSNAConfigPMKLifetime - Maximum lifetime of a PMK

dot11 MIB variable for the maximum lifetime of a PMK in the PMK cache (unit: seconds).

This timeout value is used in mesh STA to retransmit SAE Authentication frame. By default: 1000 milliseconds.

§ driver_param

char* wpa_config::driver_param

driver_param - Driver interface parameters

This text string is passed to the selected driver interface with the optional struct wpa_driver_ops::set_param() handler. This can be used to configure driver specific options without having to add new driver interface functionality.

§ dtim_period

int wpa_config::dtim_period

dtim_period - Default DTIM period in Beacon intervals

This parameter can be used to set the default value for network blocks that do not specify dtim_period.

§ eapol_version

int wpa_config::eapol_version

eapol_version - IEEE 802.1X/EAPOL version number

wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines EAPOL version 2. However, there are many APs that do not handle the new version number correctly (they seem to drop the frames completely). In order to make wpa_supplicant interoperate with these APs, the version number is set to 1 by default. This configuration value can be used to set it to the new version (2).

§ ext_password_backend

char* wpa_config::ext_password_backend

If this is set (any octet is non-zero), scans will be used to request response only from BSSes belonging to the specified Homogeneous ESS. This is used only if interworking is enabled.

§ ignore_old_scan_res

int wpa_config::ignore_old_scan_res

ignore_old_scan_res - Ignore scan results older than request

The driver may have a cache of scan results that makes it return information that is older than our scan trigger. This parameter can be used to configure such old information to be ignored instead of allowing it to update the internal BSS table.

§ key_mgmt_offload

int wpa_config::key_mgmt_offload

key_mgmt_offload - Use key management offload

Key management offload should be used if the device supports it. Key management offload is the capability of a device operating as a station to do the exchange necessary to establish temporal keys during initial RSN connection, after roaming, or during a PTK rekeying operation.

§ mac_addr

int wpa_config::mac_addr

mac_addr - MAC address policy default

0 = use permanent MAC address 1 = use random MAC address for each ESS connection 2 = like 1, but maintain OUI (with local admin bit set)

p2p_go_freq_change_policy - The GO frequency change policy

This controls the behavior of the GO when there is a change in the map of the currently used frequencies in case more than one channel is supported.

: Prefer working in a single channel mode if possible. In case the GO is the only interface using its frequency and there are other station interfaces on other frequencies, the GO will migrate to one of these frequencies.

: Same as P2P_GO_FREQ_MOVE_SCM, but a transition is possible only in case one of the other used frequencies is one of the frequencies in the intersection of the frequency list of the local device and the peer device.

: Prefer to stay on the current frequency.

: Same as P2P_GO_FREQ_MOVE_SCM_PEER_SUPPORTS but a transition is possible only if all the group members advertise eCSA support.

§ p2p_go_ht40

int wpa_config::p2p_go_ht40

p2p_go_ht40 - Default mode for HT40 enable when operating as GO.

This will take effect for p2p_group_add, p2p_connect, and p2p_invite. Note that regulatory constraints and driver capabilities are consulted anyway, so setting it to 1 can't do real harm. By default: 0 (disabled)

§ p2p_go_vht

int wpa_config::p2p_go_vht

p2p_go_vht - Default mode for VHT enable when operating as GO

This will take effect for p2p_group_add, p2p_connect, and p2p_invite. Note that regulatory constraints and driver capabilities are consulted anyway, so setting it to 1 can't do real harm. By default: 0 (disabled)

§ p2p_group_idle

int wpa_config::p2p_group_idle

p2p_group_idle - Maximum idle time in seconds for P2P group

This value controls how long a P2P group is maintained after there is no other members in the group. As a GO, this means no associated stations in the group. As a P2P client, this means no GO seen in scan results. The maximum idle time is specified in seconds with 0 indicating no time limit, i.e., the P2P group remains in active state indefinitely until explicitly removed. As a P2P client, the maximum idle time of P2P_MAX_CLIENT_IDLE seconds is enforced, i.e., this parameter is mainly meant for GO use and for P2P client, it can only be used to reduce the default timeout to smaller value. A special value -1 can be used to configure immediate removal of the group for P2P client role on any disconnection after the data connection has been established.

§ p2p_no_group_iface

int wpa_config::p2p_no_group_iface

p2p_no_group_iface - Whether group interfaces can be used

By default, wpa_supplicant will create a separate interface for P2P group operations if the driver supports this. This functionality can be disabled by setting this parameter to 1. In that case, the same interface that was used for the P2P management operations is used also for the group operation.

§ p2p_passphrase_len

unsigned int wpa_config::p2p_passphrase_len

p2p_passphrase_len - Passphrase length (8..63) for P2P GO

This parameter controls the length of the random passphrase that is generated at the GO.

§ p2p_search_delay

unsigned int wpa_config::p2p_search_delay

p2p_search_delay - Extra delay between concurrent search iterations

Add extra delay (in milliseconds) between search iterations when there is a concurrent operation to make p2p_find friendlier to concurrent operations by avoiding it from taking 100% of radio resources.

§ passive_scan

int wpa_config::passive_scan

passive_scan - Whether to force passive scan for network connection

This parameter can be used to force only passive scanning to be used for network connection cases. It should be noted that this will slow down scan operations and reduce likelihood of finding the AP. In addition, some use cases will override this due to functional requirements, e.g., for finding an AP that uses hidden SSID (scan_ssid=1) or P2P device discovery.

§ pbc_in_m1

int wpa_config::pbc_in_m1

pbc_in_m1 - AP mode WPS probing workaround for PBC with Windows 7

Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting as a Registrar and using M1 from the AP. The config methods attribute in that message is supposed to indicate only the configuration method supported by the AP in Enrollee role, i.e., to add an external Registrar. For that case, PBC shall not be used and as such, the PushButton config method is removed from M1 by default. If pbc_in_m1=1 is included in the configuration file, the PushButton config method is left in M1 (if included in config_methods parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label in the AP).

§ pcsc_pin

char* wpa_config::pcsc_pin

pcsc_pin - PIN for USIM, GSM SIM, and smartcards

This field is used to configure PIN for SIM/USIM for EAP-SIM and EAP-AKA. If left out, this will be asked through control interface.

§ pcsc_reader

char* wpa_config::pcsc_reader

pcsc_reader - PC/SC reader name prefix

If not NULL, PC/SC reader with a name that matches this prefix is initialized for SIM/USIM access. Empty string can be used to match the first available reader.

§ pkcs11_engine_path

char* wpa_config::pkcs11_engine_path

pkcs11_engine_path - Path to the OpenSSL engine for PKCS#11

This is an OpenSSL specific configuration option for loading PKCS#11 engine (engine_pkcs11.so); if NULL, this engine is not loaded.

§ pkcs11_module_path

char* wpa_config::pkcs11_module_path

pkcs11_module_path - Path to the OpenSSL OpenSC/PKCS#11 module

This is an OpenSSL specific configuration option for configuring path to OpenSC/PKCS#11 engine (opensc-pkcs11.so); if NULL, this module is not loaded.

§ pmf

enum mfp_options wpa_config::pmf

pmf - Whether to enable/require PMF by default

By default, PMF is disabled unless enabled by the per-network ieee80211w=1 or ieee80211w=2 parameter. pmf=1/2 can be used to change this default behavior for RSN network (this is not applicable for non-RSN cases).

§ preassoc_mac_addr

int wpa_config::preassoc_mac_addr

preassoc_mac_addr - Pre-association MAC address policy

0 = use permanent MAC address 1 = use random MAC address 2 = like 1, but maintain OUI (with local admin bit set)

§ sae_groups

int* wpa_config::sae_groups

sae_groups - Preference list of enabled groups for SAE

By default (if this parameter is not set), the mandatory group 19 (ECC group defined over a 256-bit prime order field) is preferred, but other groups are also enabled. If this parameter is set, the groups will be tried in the indicated order.

§ scan_cur_freq

int wpa_config::scan_cur_freq

scan_cur_freq - Whether to scan only the current channel

If true, attempt to scan only the current channel if any other VIFs on this radio are already associated on a particular channel.

§ sched_scan_plans

char* wpa_config::sched_scan_plans

sched_scan_plans - Scan plans for scheduled scan

Each scan plan specifies the interval between scans and the number of iterations. The last scan plan only specifies the scan interval and will be run infinitely.

format: <interval:iterations> <interval2:iterations2> ... <interval>

§ ssid

struct wpa_ssid* wpa_config::ssid

ssid - Head of the global network list

This is the head for the list of all the configured networks.

§ tdls_external_control

int wpa_config::tdls_external_control

tdls_external_control - External control for TDLS setup requests

Enable TDLS mode where external programs are given the control to specify the TDLS link to get established to the driver. The driver requests the TDLS setup to the supplicant only for the specified TDLS peers.

§ update_config

int wpa_config::update_config

update_config - Is wpa_supplicant allowed to update configuration

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

§ user_mpm

int wpa_config::user_mpm

user_mpm - MPM residency

0: MPM lives in driver. 1: wpa_supplicant handles peering and station allocation.

If AMPE or SAE is enabled, the MPM is always in userspace.

§ wowlan_triggers

char* wpa_config::wowlan_triggers

wowlan_triggers - Wake-on-WLAN triggers

If set, these wowlan triggers will be configured.

§ wpa_rsc_relaxation

int wpa_config::wpa_rsc_relaxation

wpa_rsc_relaxation - RSC relaxation on GTK installation

Values: 0 - use the EAPOL-Key RSC value on GTK installation 1 - use the null RSC if a bogus RSC value is detected in message 3 of 4-Way Handshake or message 1 of Group Key Handshake.

§ wps_cred_processing

int wpa_config::wps_cred_processing

wps_cred_processing - Credential processing

0 = process received credentials internally 1 = do not process received credentials; just pass them over ctrl_iface to external program(s) 2 = process received credentials internally and pass them over ctrl_iface to external program(s)

§ wps_nfc_pw_from_config

int wpa_config::wps_nfc_pw_from_config

wps_nfc_pw_from_config - NFC Device Password was read from config

This parameter can be determined whether the NFC Device Password was included in the configuration (1) or generated dynamically (0). Only the former case is re-written back to the configuration file.

§ wps_priority
