Data Structures
struct	eap_method
	EAP method interface This structure defines the EAP method interface. Each method will need to register its own EAP type, EAP name, and set of function pointers for method specific operations. This interface is based on section 4.4 of RFC 4137. More...
struct	eap_sm
	EAP state machine data. More...

Detailed Description

hostapd / EAP Authenticator state machine internal structures (RFC 4137)

Function Documentation

void void eap_sm_process_nak	(	struct eap_sm *	sm,
		const u8 *	nak_list,
		size_t	len
	)

Process EAP-Response/Nak.

Parameters

sm	Pointer to EAP state machine allocated with eap_server_sm_init()
nak_list	Nak list (allowed methods) from the supplicant
len	Length of nak_list in bytes

This function is called when EAP-Response/Nak is received from the supplicant. This can happen for both phase 1 and phase 2 authentications.

int eap_user_get	(	struct eap_sm *	sm,
		const u8 *	identity,
		size_t	identity_len,
		int	phase2
	)

Fetch user information from the database.

Parameters

sm	Pointer to EAP state machine allocated with eap_server_sm_init()
identity	Identity (User-Name) of the user
identity_len	Length of identity in bytes
phase2	0 = EAP phase1 user, 1 = EAP phase2 (tunneled) user

Returns

0 on success, or -1 on failure

This function is used to fetch user information for EAP. The user will be selected based on the specified identity. sm->user and sm->user_eap_method_index are updated for the new user when a matching user is found. sm->user can be used to get user information (e.g., password).
