P2P: Add option to force SSID/passphrase for GO Negotiation
An existing persistent group information can now be used to force GO
Negotiation to use the previously used SSID/passphrase from a persistent

a new P2P peer to join the group (i.e., use GO Negotiation with GO
intent 15 instead of starting an autonomous GO and using invitation),
e.g., in case a GO Negotiation Request is received from a peer while we
are not running as a GO. The persistent group to use for parameters is
indicated with persistent=<network id> parameter to p2p_connect.
wpa_supplicant can now be requested to automatically figure out whether
the indicated peer is operating as a GO and if so, use join-a-group

The p2p_dev_addr parameter in the P2P-PROV-DISC-FAILURE event (added in

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.
The man page source was not up-to-date with removed driver wrappers,
so bring in the wpa_supplicant/README changes to make this somewhat

P2P: Extend use of group formation timeout until end of 4-way handshake
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.
P2P: Fix p2p_connect join scan handler in error cases
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: Add automatic GO Negotiation vs. join-a-group selection
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
formation. 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.
P2P: Clear P2P_DEV_SD_INFO when new wildcard SD query is added
Unlike the unicast SD queries, the queries directed to all peers depend
on P2P_DEV_SD_INFO flag being cleared to allow the query to be sent to
a peer that has previously replied to any SD query.
AP: Reschedule ap_handle_timer event on (re)association
Previously, the timeout scheduled during the previous association was
used after reassociation if the STA entry had not yet been removed. The
next timeout does not need to happen that quickly, so reschedule it
during reassociation.
AP: Reset STA timeout_next on driver-based-SME association
The next ap_handle_timer action was already cleared when association
is handled with user space -based SME. However, this step was missing
from the driver callback for indicating new association. This could
result in the first ap_handle_timer timeout on the new association
removing the station unexpectedly. Fix this by resetting the timeout_next
in hostapd_notif_assoc().
Fix EAP/WPS to PSK transition on reassociation in authenticator
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.

P2P: Abort join-group operation if concurrent group cannot be supported

in both phases, but does not work properly if different CA certificates

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

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.

just isn't safe, so make the teardown portion of this async.

Change reason code for AP mode BSS termination to 3
Use reason code 3 (Deauthenticated because sending STA is leaving)
instead of reason code 2 (Previous authentication ot valid) in the
Deauthentication frame sent at the time a BSS is terminated. This is
more accurate reason for the message and allows the stations to get
better understand on why they were disconnected. This can be useful
especially for P2P clients that can use this as a signal that the
P2P group session was ended per P2P specification section 3.2.9.
