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