Function Documentation

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).
