Function Documentation

int get_netif_info	(	const char *	net_if,
		unsigned *	ip_addr,
		char **	ip_addr_text,
		u8	mac[ETH_ALEN]
	)

Get hw and IP addresses for network device.

Parameters

net_if	Selected network interface name
ip_addr	Buffer for returning IP address in network byte order
ip_addr_text	Buffer for returning a pointer to allocated IP address text
mac	Buffer for returning MAC address

Returns

0 on success, -1 on failure

struct subscription* subscription_start	(	struct upnp_wps_device_sm *	sm,
		const char *	callback_urls
	)

Remember a UPnP control point to send events to.

Parameters

sm	WPS UPnP state machine from upnp_wps_device_init()
callback_urls	Callback URLs

Returns

NULL on error, or pointer to new subscription structure.

void upnp_wps_device_deinit	(	struct upnp_wps_device_sm *	sm,
		void *	priv
	)

Deinitialize WPS UPnP.

Parameters

sm	WPS UPnP state machine from upnp_wps_device_init()
priv	External context data that was used in upnp_wps_device_init() call

struct upnp_wps_device_sm* upnp_wps_device_init	(	struct upnp_wps_device_ctx *	ctx,
		struct wps_context *	wps,
		void *	priv,
		char *	net_if
	)

Initialize WPS UPnP.

Parameters

ctx	callback table; we must eventually free it
wps	Pointer to longterm WPS context
priv	External context data that will be used in callbacks
net_if	Selected network interface name

Returns

WPS UPnP state or NULL on failure

int upnp_wps_device_send_wlan_event	(	struct upnp_wps_device_sm *	sm,
		const u8	from_mac_addr[ETH_ALEN],
		enum upnp_wps_wlanevent_type	ev_type,
		const struct wpabuf *	msg
	)

Event notification.

Parameters

sm	WPS UPnP state machine from upnp_wps_device_init()
from_mac_addr	Source (Enrollee) MAC address for the event
ev_type	Event type
msg	Event data

Returns

0 on success, -1 on failure

Tell external Registrars (UPnP control points) that something happened. In particular, events include WPS messages from clients that are proxied to external Registrars.

int upnp_wps_subscribers

(

struct upnp_wps_device_sm *

sm

)

Check whether there are any event subscribers.

Parameters

sm	WPS UPnP state machine from upnp_wps_device_init()

Returns

0 if no subscribers, 1 if subscribers
