Detailed Description

wpa_supplicant - P2P

Function Documentation

void wpas_p2p_cancel_remain_on_channel_cb ( struct wpa_supplicant wpa_s,
unsigned int  freq 
)

Remain-on-channel timeout.

Parameters
wpa_sPointer to wpa_supplicant data from wpa_supplicant_add_iface()
freqFrequency 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_sPointer to wpa_supplicant data from wpa_supplicant_add_iface()
peer_addrAddress of the peer P2P Device
pinPIN to use during provisioning or NULL to indicate PBC mode
persistent_groupWhether to create a persistent group
auto_joinWhether to select join vs. GO Negotiation automatically
joinWhether to join an existing group (as a client) instead of starting Group Owner negotiation; peer_addr is BSSID in that case
authWhether to only authorize the connection instead of doing that and initiating Group Owner negotiation
go_intentGO Intent or -1 to use default
freqFrequency for the group or 0 for auto-selection
persistent_idPersistent group credentials to use for forcing GO parameters or -1 to generate new values (SSID/passphrase)
pdWhether to send Provision Discovery prior to GO Negotiation as an interoperability workaround when initiating group formation
ht40Start GO with 40 MHz channel width
vhtStart 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_sPointer 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_sPointer 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_sPointer to wpa_supplicant data from wpa_supplicant_add_iface()
persistent_groupWhether to create a persistent group
freqFrequency for the group or 0 to indicate no hardcoding
ht40Start GO with 40 MHz channel width
vhtStart 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_sPointer to wpa_supplicant data from wpa_supplicant_add_iface()
ifnameNetwork 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
globalPointer to global data from wpa_supplicant_init()
wpa_sPointer 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_sPointer to wpa_supplicant data from wpa_supplicant_add_iface()
freqFrequency of the channel in MHz
durationDuration 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.
