92 * enum wpa_states - wpa_supplicant state
94 * These enumeration values are used to indicate the current wpa_supplicant
95 * state (wpa_s->wpa_state). The current state can be retrieved with
96 * wpa_supplicant_get_state() function and the state can be changed by calling
97 * wpa_supplicant_set_state(). In WPA state machine (wpa.c and preauth.c), the
98 * wrapper functions wpa_sm_get_state() and wpa_sm_set_state() should be used
99 * to access the state variable.
103 * WPA_DISCONNECTED - Disconnected state
105 * This state indicates that client is not associated, but is likely to
106 * start looking for an access point. This state is entered when a
107 * connection is lost.
112 * WPA_INACTIVE - Inactive state (wpa_supplicant disabled)
114 * This state is entered if there are no enabled networks in the
115 * configuration. wpa_supplicant is not trying to associate with a new
116 * network and external interaction (e.g., ctrl_iface call to add or
117 * enable a network) is needed to start association.
122 * WPA_SCANNING - Scanning for a network
124 * This state is entered when wpa_supplicant starts scanning for a
130 * WPA_ASSOCIATING - Trying to associate with a BSS/SSID
132 * This state is entered when wpa_supplicant has found a suitable BSS
133 * to associate with and the driver is configured to try to associate
134 * with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this
135 * state is entered when the driver is configured to try to associate
136 * with a network using the configured SSID and security policy.
141 * WPA_ASSOCIATED - Association completed
143 * This state is entered when the driver reports that association has
144 * been successfully completed with an AP. If IEEE 802.1X is used
145 * (with or without WPA/WPA2), wpa_supplicant remains in this state
146 * until the IEEE 802.1X/EAPOL authentication has been completed.
151 * WPA_4WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress
153 * This state is entered when WPA/WPA2 4-Way Handshake is started. In
154 * case of WPA-PSK, this happens when receiving the first EAPOL-Key
155 * frame after association. In case of WPA-EAP, this state is entered
156 * when the IEEE 802.1X/EAPOL authentication has been completed.
161 * WPA_GROUP_HANDSHAKE - WPA Group Key Handshake in progress
163 * This state is entered when 4-Way Key Handshake has been completed
164 * (i.e., when the supplicant sends out message 4/4) and when Group
165 * Key rekeying is started by the AP (i.e., when supplicant receives
171 * WPA_COMPLETED - All authentication completed
173 * This state is entered when the full authentication process is
174 * completed. In case of WPA2, this happens when the 4-Way Handshake is
175 * successfully completed. With WPA, this state is entered after the
176 * Group Key Handshake; with IEEE 802.1X (non-WPA) connection is
177 * completed after dynamic keys are received (or if not used, after
178 * the EAP authentication has been completed). With static WEP keys and
179 * plaintext connections, this state is entered when an association
180 * has been completed.
182 * This state indicates that the supplicant has completed its
183 * processing for the association phase and that data connection is
