53 enum supplicant_state {
55 * WPA_DISCONNECTED - Disconnected state
57 * This state indicates that client is not associated, but is likely to
58 * start looking for an access point. This state is entered when a
64 * WPA_INACTIVE - Inactive state (wpa_supplicant disabled)
66 * This state is entered if there are no enabled networks in the
67 * configuration. wpa_supplicant is not trying to associate with a new
68 * network and external interaction (e.g., ctrl_iface call to add or
69 * enable a network) is needed to start association.
74 * WPA_SCANNING - Scanning for a network
76 * This state is entered when wpa_supplicant starts scanning for a
82 * WPA_ASSOCIATING - Trying to associate with a BSS/SSID
84 * This state is entered when wpa_supplicant has found a suitable BSS
85 * to associate with and the driver is configured to try to associate
86 * with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this
87 * state is entered when the driver is configured to try to associate
88 * with a network using the configured SSID and security policy.
93 * WPA_ASSOCIATED - Association completed
95 * This state is entered when the driver reports that association has
96 * been successfully completed with an AP. If IEEE 802.1X is used
97 * (with or without WPA/WPA2), wpa_supplicant remains in this state
98 * until the IEEE 802.1X/EAPOL authentication has been completed.
103 * WPA_4WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress
105 * This state is entered when WPA/WPA2 4-Way Handshake is started. In
106 * case of WPA-PSK, this happens when receiving the first EAPOL-Key
107 * frame after association. In case of WPA-EAP, this state is entered
108 * when the IEEE 802.1X/EAPOL authentication has been completed.
113 * WPA_GROUP_HANDSHAKE - WPA Group Key Handshake in progress
115 * This state is entered when 4-Way Key Handshake has been completed
116 * (i.e., when the supplicant sends out message 4/4) and when Group
117 * Key rekeying is started by the AP (i.e., when supplicant receives
123 * WPA_COMPLETED - All authentication completed
125 * This state is entered when the full authentication process is
126 * completed. In case of WPA2, this happens when the 4-Way Handshake is
127 * successfully completed. With WPA, this state is entered after the
128 * Group Key Handshake; with IEEE 802.1X (non-WPA) connection is
129 * completed after dynamic keys are received (or if not used, after
130 * the EAP authentication has been completed). With static WEP keys and
131 * plaintext connections, this state is entered when an association
132 * has been completed.
134 * This state indicates that the supplicant has completed its
135 * processing for the association phase and that data connection is
141 * WPA_INVALID - Invalid state (parsing error)
143 * This state is returned if the string input is invalid. It is not
144 * an official wpa_supplicant state.
