120 * enum wpa_states - wpa_supplicant state
122 * These enumeration values are used to indicate the current wpa_supplicant
123 * state (wpa_s->wpa_state). The current state can be retrieved with
124 * wpa_supplicant_get_state() function and the state can be changed by calling
125 * wpa_supplicant_set_state(). In WPA state machine (wpa.c and preauth.c), the
126 * wrapper functions wpa_sm_get_state() and wpa_sm_set_state() should be used
127 * to access the state variable.
131 * WPA_DISCONNECTED - Disconnected state
133 * This state indicates that client is not associated, but is likely to
134 * start looking for an access point. This state is entered when a
135 * connection is lost.
140 * WPA_INTERFACE_DISABLED - Interface disabled
142 * This stat eis entered if the network interface is disabled, e.g.,
143 * due to rfkill. wpa_supplicant refuses any new operations that would
144 * use the radio until the interface has been enabled.
146 WPA_INTERFACE_DISABLED,
149 * WPA_INACTIVE - Inactive state (wpa_supplicant disabled)
151 * This state is entered if there are no enabled networks in the
152 * configuration. wpa_supplicant is not trying to associate with a new
153 * network and external interaction (e.g., ctrl_iface call to add or
154 * enable a network) is needed to start association.
159 * WPA_SCANNING - Scanning for a network
161 * This state is entered when wpa_supplicant starts scanning for a
167 * WPA_AUTHENTICATING - Trying to authenticate with a BSS/SSID
169 * This state is entered when wpa_supplicant has found a suitable BSS
170 * to authenticate with and the driver is configured to try to
171 * authenticate with this BSS. This state is used only with drivers
172 * that use wpa_supplicant as the SME.
177 * WPA_ASSOCIATING - Trying to associate with a BSS/SSID
179 * This state is entered when wpa_supplicant has found a suitable BSS
180 * to associate with and the driver is configured to try to associate
181 * with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this
182 * state is entered when the driver is configured to try to associate
183 * with a network using the configured SSID and security policy.
188 * WPA_ASSOCIATED - Association completed
190 * This state is entered when the driver reports that association has
191 * been successfully completed with an AP. If IEEE 802.1X is used
192 * (with or without WPA/WPA2), wpa_supplicant remains in this state
193 * until the IEEE 802.1X/EAPOL authentication has been completed.
198 * WPA_4WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress
200 * This state is entered when WPA/WPA2 4-Way Handshake is started. In
201 * case of WPA-PSK, this happens when receiving the first EAPOL-Key
202 * frame after association. In case of WPA-EAP, this state is entered
203 * when the IEEE 802.1X/EAPOL authentication has been completed.
208 * WPA_GROUP_HANDSHAKE - WPA Group Key Handshake in progress
210 * This state is entered when 4-Way Key Handshake has been completed
211 * (i.e., when the supplicant sends out message 4/4) and when Group
212 * Key rekeying is started by the AP (i.e., when supplicant receives
218 * WPA_COMPLETED - All authentication completed
220 * This state is entered when the full authentication process is
221 * completed. In case of WPA2, this happens when the 4-Way Handshake is
222 * successfully completed. With WPA, this state is entered after the
223 * Group Key Handshake; with IEEE 802.1X (non-WPA) connection is
224 * completed after dynamic keys are received (or if not used, after
225 * the EAP authentication has been completed). With static WEP keys and
226 * plaintext connections, this state is entered when an association
227 * has been completed.
229 * This state indicates that the supplicant has completed its
230 * processing for the association phase and that data connection is
