Enumeration Type Documentation

enum wpa_states

enum wpa_states - wpa_supplicant state

These enumeration values are used to indicate the current wpa_supplicant state (wpa_s->wpa_state). The current state can be retrieved with wpa_supplicant_get_state() function and the state can be changed by calling wpa_supplicant_set_state(). In WPA state machine (wpa.c and preauth.c), the wrapper functions wpa_sm_get_state() and wpa_sm_set_state() should be used to access the state variable.

Enumeration values:
WPA_DISCONNECTED  Disconnected state.

This state indicates that client is not associated, but is likely to start looking for an access point. This state is entered when a connection is lost.

WPA_INACTIVE  Inactive state (wpa_supplicant disabled).

This state is entered if there are no enabled networks in the configuration. wpa_supplicant is not trying to associate with a new network and external interaction (e.g., ctrl_iface call to add or enable a network) is needed to start association.

WPA_SCANNING  Scanning for a network.

This state is entered when wpa_supplicant starts scanning for a network.

WPA_ASSOCIATING  Trying to associate with a BSS/SSID.

This state is entered when wpa_supplicant has found a suitable BSS to associate with and the driver is configured to try to associate with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this state is entered when the driver is configured to try to associate with a network using the configured SSID and security policy.

WPA_ASSOCIATED  Association completed.

This state is entered when the driver reports that association has been successfully completed with an AP. If IEEE 802.1X is used (with or without WPA/WPA2), wpa_supplicant remains in this state until the IEEE 802.1X/EAPOL authentication has been completed.

WPA_4WAY_HANDSHAKE  WPA 4-Way Key Handshake in progress.

This state is entered when WPA/WPA2 4-Way Handshake is started. In case of WPA-PSK, this happens when receiving the first EAPOL-Key frame after association. In case of WPA-EAP, this state is entered when the IEEE 802.1X/EAPOL authentication has been completed.

WPA_GROUP_HANDSHAKE  WPA Group Key Handshake in progress.

This state is entered when 4-Way Key Handshake has been completed (i.e., when the supplicant sends out message 4/4) and when Group Key rekeying is started by the AP (i.e., when supplicant receives message 1/2).

WPA_COMPLETED  All authentication completed.

This state is entered when the full authentication process is completed. In case of WPA2, this happens when the 4-Way Handshake is successfully completed. With WPA, this state is entered after the Group Key Handshake; with IEEE 802.1X (non-WPA) connection is completed after dynamic keys are received (or if not used, after the EAP authentication has been completed). With static WEP keys and plaintext connections, this state is entered when an association has been completed.

This state indicates that the supplicant has completed its processing for the association phase and that data connection is fully configured.
