462a7439e1 Add p2p_go_max_inactivity config option
This enables setting a different max inactivity timeout for P2P GO.
This timeout is used to detect inactive clients. In some scenarios
it may be useful to have control over this and set a shorter timeout
than the default 300s. For example when running STA and P2P GO interfaces
concurrently, the STA interface may perform scans which may cause the
GO to miss a disassoc / deauth frames from a client and keep assuming
that the client is connected until the inactivity detection kicks in.
300 secs is a bit too long for such scenarios and creates a bad user
experience.

c66cf68d5c P2P: Fix fallback to GO Negotiation to avoid PD-before-join timeout
The wpas_p2p_pd_before_join_timeout could be left behind if the PD
Request in p2p_connect-auto case does not succeed. This timeout can
result in unexpected operations since it could trigger join operation
while going through GO Negotiation. Fix this by canceling the timeout
when falling back to GO Negotiation.

73ccd08378 P2P: Fix group formation timeout on GO during WPS step
Commit 361cdf3400 changed the way the
group formation timeout is used on P2P client. However, it resulted in
clearing the timeout on the GO when the GO started beaconing. This is
not correct since the timeout is supposed to be maintained until at
least the completion of the WPS provisioning step. Fix this regression
by clearing the timeout here only in the case we are not GO in group
formation phase.

The previous version set scan_res_handler unconditionally and then
cleared it if scan request failed. This can result in incorrect clearing

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

single-channel scans during the join, fall back to GO Negotiation.

wpa_drv_scan() may fail for the initial p2p_connect join scan request,

result in partial scan results (e.g., from p2p_find social scan) from
being used as full results for join (or now more importantly for
p2p_connect auto) purposes. Fix this by registering the new scan result
handler only if wpa_drv_scan() returns success.

eb6f8c2bd4 P2P: Fix crash for failure case when WSC PIN is entered incorrectly
When forming a P2P group using WSC PIN method, if the PIN is entered
incorrectly the P2P client supplicant instance will crash as a result
of cleanup happening on data that is still in use in a case where a
separate P2P group interface is used.

For example, here is the path for the first crash:
eap_wsc_process():
- creates struct wpabuf tmpbuf; on the stack
- sets data->in_buf = &tmpbuf;
- calls wps_process_msg()
- which calls wps_process_wsc_msg()
- which, in case WPS_M4: calls wps_fail_event()
- which calls wps->event_cb()
- wps->event_cb = wpa_supplicant_wps_event()
- wpa_supplicant_wps_event()
- wpa_supplicant_wps_event_fail()
- which calls wpas_clear_wps()
- which calls wpas_notify_network_removed()
- which calls wpas_p2p_network_removed()
- which calls wpas_p2p_group_formation_timeout()
- which calls wpas_group_formation_completed()
- which calls wpas_p2p_group_delete()
- which calls wpa_supplicant_remove_iface()
- which calls wpa_supplicant_deinit_iface()
- which calls wpa_supplicant_cleanup()
- which calls eapol_sm_deinit()
- ... which eventually uses the ptr data->in_buf to free tmpbuf, our
stack variable and then the supplicant crashes

If you fix this crash, you'll hit another. Fix it and then a segfault.
The way we're cleaning up and deleting data from under ourselves here
just isn't safe, so make the teardown portion of this async.

2d43d37ff2 DBus: Add ability to report probe requests
Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify

As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.

Also, since it was never really populated, we can redefine the signal

a7a30b90e5 P2P: Fix group idle timer cancellation on group removal
The wpas_p2p_group_idle_timeout was getting cancelled in the beginning
of wpas_p2p_group_delete(). However, in the case of P2P client role,
this function called wpa_supplicant_deauthenticate() next and that ended
up changing state to WPA_DISCONNECTED which resulted in
wpas_p2p_notif_disconnected() rescheduling the timeout. This left the
unexpected timeout behind after the group was removed. If another group
operation was started within P2P_MAX_CLIENT_IDLE (10) seconds, that
timeout could end up terminating the group while it was still being set
up.

Fix this by reordering wpas_p2p_group_delete() to cancel the group idle
timeout only after having called wpa_supplicant_deauthenticate(). The
group idle timeout is still rescheduled, but it gets removed immediately
afterwards when the actual group information is being cleared.

b1aebbc427 P2P: Do not expire peer entry if we are connected to the peer
Even though we may not update P2P peer entry while connected to the
peer as a P2P client, we should not be expiring a P2P peer entry while
that peer is the GO in a group where we are connected as a P2P client.

433cd2ce65 Stop sched_scan in number of cases where it should not be running
When a P2P group is removed, we better not leave possibly started
sched_scan running. This could happen when a separate group interface
was not used.

In addition, it looks safer to explicitly stop sched_scan before
starting P2P Listen or Find operations to make sure the offloaded
scanning is not running when doing similar P2P operations.
