Function Documentation

free_radius_attr()

void free_radius_attr

(

struct hostapd_radius_attr *

attr

)

get_password_attribute()

struct hostapd_radius_attr* get_password_attribute	(	const uint8_t *	req_authenticator,
		const uint8_t *	secret,
		size_t	secret_len,
		const uint8_t *	key,
		size_t	key_len
	)

get_vlan_attribute()

struct hostapd_radius_attr* get_vlan_attribute

(

uint16_t

vlan_id

)

init_radius_client()

struct radius_client* init_radius_client	(	struct radius_conf *	conf,
		mac_conn_fn	mac_conn_fn,
		void *	mac_conn_arg
	)

radius_server_deinit()

void radius_server_deinit

(

struct radius_server_data *

data

)

radius_server_deinit - Deinitialize RADIUS server @data: RADIUS server context from radius_server_init()

radius_server_free_clients()

void radius_server_free_clients	(	struct radius_server_data *	data,
		struct radius_client *	clients
	)

radius_server_get_mib()

int radius_server_get_mib	(	struct radius_server_data *	data,
		char *	buf,
		size_t	buflen
	)

radius_server_get_mib - Get RADIUS server MIB information @data: RADIUS server context from radius_server_init() @buf: Buffer for returning the MIB data in text format @buflen: buf length in octets Returns: Number of octets written into buf

radius_server_init()

struct radius_server_data* radius_server_init	(	struct eloop_data *	eloop,
		int	auth_port,
		struct radius_client *	clients
	)

radius_server_init - Initialize RADIUS server @conf: Configuration for the RADIUS server Returns: Pointer to private RADIUS server context or NULL on failure

This initializes a RADIUS server instance and returns a context pointer that will be used in other calls to the RADIUS server module. The server can be deinitialize by calling radius_server_deinit().

srv_log()

void void srv_log	(	struct radius_session *	sess,
		const char *	fmt,
			...
	)
