Detailed Description

Function Documentation

void wpas_p2p_cancel_remain_on_channel_cb	(	struct wpa_supplicant *	wpa_s,
		unsigned int	freq
	)

Remain-on-channel timeout.

Parameters

wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()
freq	Frequency of the channel in MHz

This callback is called when the driver indicates that a remain-on-channel operation has been completed, i.e., the duration on the requested channel has timed out.

int wpas_p2p_connect	(	struct wpa_supplicant *	wpa_s,
		const u8 *	peer_addr,
		const char *	pin,
		enum p2p_wps_method	wps_method,
		int	persistent_group,
		int	auto_join,
		int	join,
		int	auth,
		int	go_intent,
		int	freq,
		int	persistent_id,
		int	pd,
		int	ht40,
		int	vht
	)

Request P2P Group Formation to be started.

Parameters

wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()
peer_addr	Address of the peer P2P Device
pin	PIN to use during provisioning or NULL to indicate PBC mode
persistent_group	Whether to create a persistent group
auto_join	Whether to select join vs. GO Negotiation automatically
join	Whether to join an existing group (as a client) instead of starting Group Owner negotiation; peer_addr is BSSID in that case
auth	Whether to only authorize the connection instead of doing that and initiating Group Owner negotiation
go_intent	GO Intent or -1 to use default
freq	Frequency for the group or 0 for auto-selection
persistent_id	Persistent group credentials to use for forcing GO parameters or -1 to generate new values (SSID/passphrase)
pd	Whether to send Provision Discovery prior to GO Negotiation as an interoperability workaround when initiating group formation
ht40	Start GO with 40 MHz channel width
vht	Start GO with VHT support

Returns: 0 or new PIN (if pin was NULL) on success, -1 on unspecified failure, -2 on failure due to channel not currently available, -3 if forced channel is not supported

void wpas_p2p_deinit ( struct wpa_supplicant * wpa_s )

Deinitialize per-interface P2P data.

Parameters

wpa_s Pointer to wpa_supplicant data from wpa_supplicant_add_iface()

This function deinitialize per-interface P2P data.

int wpas_p2p_disconnect ( struct wpa_supplicant * wpa_s )

Disconnect from a P2P Group.

Parameters

wpa_s Pointer to wpa_supplicant data

Returns: 0 on success, -1 on failure

This can be used to disconnect from a group in which the local end is a P2P Client or to end a P2P Group in case the local end is the Group Owner. If a virtual network interface was created for this group, that interface will be removed. Otherwise, only the configured P2P group network will be removed from the interface.

int wpas_p2p_group_add	(	struct wpa_supplicant *	wpa_s,
		int	persistent_group,
		int	freq,
		int	ht40,
		int	vht
	)

Add a new P2P group with local end as Group Owner.

Parameters

wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()
persistent_group	Whether to create a persistent group
freq	Frequency for the group or 0 to indicate no hardcoding
ht40	Start GO with 40 MHz channel width
vht	Start GO with VHT support

Returns: 0 on success, -1 on failure

This function creates a new P2P group with the local end as the Group Owner, i.e., without using Group Owner Negotiation.

int wpas_p2p_group_remove	(	struct wpa_supplicant *	wpa_s,
		const char *	ifname
	)

Remove a P2P group.

Parameters

wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()
ifname	Network interface name of the group interface or "*" to remove all groups

Returns: 0 on success, -1 on failure

This function is used to remove a P2P group. This can be used to disconnect from a group in which the local end is a P2P Client or to end a P2P Group in case the local end is the Group Owner. If a virtual network interface was created for this group, that interface will be removed. Otherwise, only the configured P2P group network will be removed from the interface.

int wpas_p2p_init	(	struct wpa_global *	global,
		struct wpa_supplicant *	wpa_s
	)

Initialize P2P module for wpa_supplicant.

Parameters

global	Pointer to global data from wpa_supplicant_init()
wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()

Returns: 0 on success, -1 on failure

void wpas_p2p_network_removed	(	struct wpa_supplicant *	wpa_s,
		struct wpa_ssid *	ssid
	)

Remove the network by scheduling the group formation timeout to happen immediately. The teardown code needs to be scheduled to run asynch later so that we don't delete data from under ourselves unexpectedly. Calling wpas_p2p_group_formation_timeout directly causes a series of crashes in WPS failure scenarios.

void wpas_p2p_remain_on_channel_cb	(	struct wpa_supplicant *	wpa_s,
		unsigned int	freq,
		unsigned int	duration
	)

Indication of remain-on-channel start.

Parameters

wpa_s	Pointer to wpa_supplicant data from wpa_supplicant_add_iface()
freq	Frequency of the channel in MHz
duration	Duration of the stay on the channel in milliseconds

This callback is called when the driver indicates that it has started the requested remain-on-channel duration.
