Detailed Description

Internal WPA/RSN supplicant state machine definitions.

Function Documentation

void wpa_eapol_key_send	(	struct wpa_sm *	sm,
		const u8 *	kck,
		size_t	kck_len,
		int	ver,
		const u8 *	dest,
		u16	proto,
		u8 *	msg,
		size_t	msg_len,
		u8 *	key_mic
	)

Send WPA/RSN EAPOL-Key message.

Parameters

sm	Pointer to WPA state machine data from wpa_sm_init()
kck	Key Confirmation Key (KCK, part of PTK)
kck_len	KCK length in octets
ver	Version field from Key Info
dest	Destination address for the frame
proto	Ethertype (usually ETH_P_EAPOL)
msg	EAPOL-Key message
msg_len	Length of message
key_mic	Pointer to the buffer to which the EAPOL-Key MIC is written

int wpa_supplicant_send_2_of_4	(	struct wpa_sm *	sm,
		const unsigned char *	dst,
		const struct wpa_eapol_key *	key,
		int	ver,
		const u8 *	nonce,
		const u8 *	wpa_ie,
		size_t	wpa_ie_len,
		struct wpa_ptk *	ptk
	)

Send message 2 of WPA/RSN 4-Way Handshake.

Parameters

sm	Pointer to WPA state machine data from wpa_sm_init()
dst	Destination address for the frame
key	Pointer to the EAPOL-Key frame header
ver	Version bits from EAPOL-Key Key Info
nonce	Nonce value for the EAPOL-Key frame
wpa_ie	WPA/RSN IE
wpa_ie_len	Length of the WPA/RSN IE
ptk	PTK to use for keyed hash and encryption

Returns

0 on success, -1 on failure
