60 enum supplicant_state {
62 * WPA_DISCONNECTED - Disconnected state
64 * This state indicates that client is not associated, but is likely to
65 * start looking for an access point. This state is entered when a
71 * WPA_INACTIVE - Inactive state (wpa_supplicant disabled)
73 * This state is entered if there are no enabled networks in the
74 * configuration. wpa_supplicant is not trying to associate with a new
75 * network and external interaction (e.g., ctrl_iface call to add or
76 * enable a network) is needed to start association.
81 * WPA_SCANNING - Scanning for a network
83 * This state is entered when wpa_supplicant starts scanning for a
89 * WPA_ASSOCIATING - Trying to associate with a BSS/SSID
91 * This state is entered when wpa_supplicant has found a suitable BSS
92 * to associate with and the driver is configured to try to associate
93 * with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this
94 * state is entered when the driver is configured to try to associate
95 * with a network using the configured SSID and security policy.
100 * WPA_ASSOCIATED - Association completed
102 * This state is entered when the driver reports that association has
103 * been successfully completed with an AP. If IEEE 802.1X is used
104 * (with or without WPA/WPA2), wpa_supplicant remains in this state
105 * until the IEEE 802.1X/EAPOL authentication has been completed.
110 * WPA_4WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress
112 * This state is entered when WPA/WPA2 4-Way Handshake is started. In
113 * case of WPA-PSK, this happens when receiving the first EAPOL-Key
114 * frame after association. In case of WPA-EAP, this state is entered
115 * when the IEEE 802.1X/EAPOL authentication has been completed.
120 * WPA_GROUP_HANDSHAKE - WPA Group Key Handshake in progress
122 * This state is entered when 4-Way Key Handshake has been completed
123 * (i.e., when the supplicant sends out message 4/4) and when Group
124 * Key rekeying is started by the AP (i.e., when supplicant receives
130 * WPA_COMPLETED - All authentication completed
132 * This state is entered when the full authentication process is
133 * completed. In case of WPA2, this happens when the 4-Way Handshake is
134 * successfully completed. With WPA, this state is entered after the
135 * Group Key Handshake; with IEEE 802.1X (non-WPA) connection is
136 * completed after dynamic keys are received (or if not used, after
137 * the EAP authentication has been completed). With static WEP keys and
138 * plaintext connections, this state is entered when an association
139 * has been completed.
141 * This state indicates that the supplicant has completed its
142 * processing for the association phase and that data connection is
148 * WPA_INVALID - Invalid state (parsing error)
150 * This state is returned if the string input is invalid. It is not
151 * an official wpa_supplicant state.
