Commits 17bef1e97a and
ffe98dfb88 started using p2p_add_device()
with other frames than just Probe Response frames from scan results.
However, these changes did not take into account that the PD Request
and Invitation Request frames are normally received on the our own
Listen channel, not on the Listen channel of the peer. As such, these
frames must not be used to update Listen channel information for the
peer.
Fix this by letting p2p_add_device() know whether the results are from
scan results and if not, skip the peer table updates that are specific
to Probe Response frames.

Commit d9bdba9f86 was supposed to allow

A special value p2p_group_idle=-1 can now be used to configure the P2P

Instead of relying on the P2P group idle timeout before the group
connection has been fully established, re-start the group formation
timeout in the end of the WPS provisioning step and clear it at the
successful completion of the initial 4-way handshake. This allows the
P2P group idle timeout to be set to a small value without triggering it
during the initial scan and connection attempt.

wpa_drv_scan() may fail for the initial p2p_connect join scan request,
e.g., if the driver happened to be scanning at the time the new
operation was initialized. Previously, a special scan result handler was
registered regardless of whether the new scan was started. This could
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.

p2p_connect command can now be used with an optional "auto" parameter
to request wpa_supplicant to determine automatically whether to use
join-a-group operation (if the peer is operating as a GO) or group

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.

The next ap_handle_timer action was already cleared when association

A station may move from EAP/WPS key_mgmt to PSK using re-association. In
practice, this can happen most likely with WPS when the station runs
through the provisioning step (EAP/WPS) followed by PSK authentication.
If a deauthentication event is missed from the station for whatever
reason, the EAPOL authenticator state machine could have been left
running.
This can result in various issues, including unexpected disconnection of
the station while both the 4-way handshake and EAPOL authenticator state
machines (EAP) are running at the same time when the supplicant is
trying to use PSK. Fix this by explicitly clearing EAPOL authenticator
state machine on (re)association if the new association does not use it.

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.

For concurrency scenarios we should not update the scan results without
P2P IE to P2P group interfaces. This patch is to take care if a scan has
been requested on STA interface and scan results are getting updated
from sibling to P2P group interface. A P2P GO Probe Response for a
legacy STA scan would be without P2P IE. So it will wrongly update the
BSS list of P2P group interface too when results are updated from
sibling.
Since P2P group interfaces are used only for connecting to a P2P group,
it is fine to filter out all non-P2P entries from their BSS table.
