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.

This makes it easier for external programs to handle connection type selection by offloading this to wpa_supplicant. The previously used p2p_connect join commands can be replaced with p2p_connect auto to use this new mechanism. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Use group formation timeout on persistent group GO Previously, GO considered the group to be fully re-invoked after starting beaconing on successful invitation exchange. This would leave the group running until idle timeout (which may not be enabled) or explicit removal if the client fails to connect for any reason. Since the client is expected to connect immediately after the invitation exchange that ends with status=0 (i.e., either client initiated the exchange or it responded with success), extend group formation timeout to cover that period until the first successfully completed data connection. This allows the GO to remove the group automatically if the client devices does not connect within P2P_MAX_INITIAL_CONN_WAIT_GO_REINVOKE (15) seconds.

Pass signal strength through, fix units The signal strength is currently never used as the only driver reporting it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never populated by the kernel. The kernel will (soon) populate IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that. Also, since it was never really populated, we can redefine the signal field to be in dBm units only. My next patch will also require knowing the signal strength of probe requests throughout the code (where available), so add it to the necessary APIs.

Fix disconnection event processing Commit 0d30cc240fa36905b034dc9676f9d8da0ac18e56 forced wpa_s->current_ssid and wpa_s->key_mgmt to be cleared in wpa_supplicant_mark_disassoc() which gets called from wpa_supplicant_event_disassoc(). This broke IEEE 802.1X authentication failure processing and P2P deauthentication notification (group termination). Fix this by splitting wpa_supplicant_event_disassoc() into two parts and make wpas_p2p_deauth_notif() indicate whether the interface was removed. If so, the last part of disassocition event processing is skipped. Since the wpa_supplicant_mark_disassoc() call is in the second part, the above mentioned issues are resolved. In addition, this cleans up the P2P group interface removal case by not trying to use fast reconnection mechanism just before the interface gets removed.

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: Do not request station mode scans during P2P operations The P2P search mechanism depends on the same scan functionality that is used for station mode scans. If these operations are being used at the same time, scan result processing is not handled properly. Avoid unexpected behavior by delaying station mode scan requests if a P2P operation is in progress. Among other things, this allows the station mode connection attempt to be continued after a P2P find or group formation has been completed if the interface is available (i.e., when the P2P group uses a separate virtual interface).

P2P: Allow older scan results to improve p2p_connect-auto robustness Previusly the peer was assumed to not be operating a GO if the BSS entry for it was not updated in the single scan run started by p2p_connect-auto. This is not very robust since a scan may miss the peer if either a Probe Request or Probe Response frame is lost. Improve robustness by assuming the peer is still operating the GO and starting the join operation. If the GO is not found during PD-for-join or the single-channel scans during the join, fall back to GO Negotiation. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

If the client side of such persistent group ends up trying to use an invalidated persistent group information, the connection will fail in 4-way handshake.

A new "P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to indicate when this happens. This makes it easier for upper layers to remove the persistent group information with "REMOVE_NETWORK <persistent group id>" if desired (e.g., based on user confirmation). In addition to indicating the error cases for persistent groups, all this type of PSK failures end up in the client removing the group with the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.
