P2P: Skip GO Neg Conf ack failure workaround of send failures The workaround to ignore no ctrl::ack received for GO Negotiation Confirmation frame was only supposed to be used when the frame was actually transmitted and just the ack was not received. However, due to the way the driver failure on transmitting the frame were reported, this ended up getting applied for all failures in sending the GO Negotiation Confirmation frame. Improve this by providing a mechanism to indicate whether send_action operations fail locally before the frame was actually transmitted or because of not receiving ack frame after having transmitted the frame.

P2P: Disable periodic NoA when non-P2P STA is connected For now, this applies to the test command that can be used to set periodic NoA (p2p_set noa). The value are stored and periodic NoA is enabled whenever there are no non-P2P STAs connected to the GO.

P2P: Add support for cross connection If enabled, cross connection allows GO to forward IPv4 packets using masquerading NAT from the P2P clients in the group to an uplink WLAN connection. This is disabled by default and can be enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device interface.

P2P: Stop connection attempt on PBC session overlap The overlap condition cannot disappear before group formation timeout hits, so there is no point in continuing in this case and failure can be indicated immediately.

int wpas_p2p_notif_pbc_overlap(struct wpa_supplicant *wpa_s);
P2P: Add mechanism for updating P2P channel list based on driver events This allows P2P channel list to be updated whenever the driver changes its list of allowed channels, e.g., based on country code from scan results.

int wpas_p2p_cancel(struct wpa_supplicant *wpa_s);
P2P: Remove P2P group on driver resource becoming unavailable Add a new driver event, EVENT_INTERFACE_UNAVAILABLE, for indicating that the driver is not able to continue operating the virtual interface in its current mode anymore, e.g., due to operating channel for GO interface forced to a DFS channel by another virtual interface. When this happens for a P2P group interface, the P2P group will be terminated and P2P-GROUP-REMOVED event shows the reason for this as follows: P2P-GROUP-REMOVED wlan0 GO reason=UNAVAILABLE
2010-10-25 18:16:11 +02:00
void wpas_p2p_interface_unavailable(struct wpa_supplicant *wpa_s);
P2P: Add support for automatic channel selection at GO The driver wrapper may now indicate the preferred channel (e.g., based on scan results) on both 2.4 GHz and 5 GHz bands (and an overall best frequency). When setting up a GO, this preference information is used to select the operating channel if configuration does not include hardcoded channel. Similarly, this information can be used during GO Negotiation to indicate preference for a specific channel based on current channel conditions. p2p_group_add command can now use special values (freq=2 and freq=5) to indicate that the GO is to be started on the specified band.

P2P: Add p2p_unauthorize command This can be used to remove authorization from a previous p2p_connect commands that has not yet resulted in completed GO Negotiation.

int wpas_p2p_unauthorize(struct wpa_supplicant *wpa_s, const char *addr);
