ab72eb5256 P2P: Accept invitations to already running persistent group
We can automatically accept invitations that are for a persistent
group that is already running. There is no need to confirm this
separately or preparare a new group interface.

9d39057c2b P2P: Stop p2p_find/p2p_listen when Invitation is accepted
When an Invitation to reinvoke a persistent group is accepted,
we need to make sure that any pending p2p_find or p2p_listen
operation gets stopped to avoid consuming all radio resources
doing device discovery while the group is being set up.

requested group is already running and if so, do not try to
start another copy of it.

ca806fb540 P2P: Indicate WPS events from AP mode only during group formation
The duplicated WPS event in the parent interface should only be used
during P2P group formation, i.e., when the WPS operation was actually
started using the parent interface. When authorizing a client to
connect to an already running group, the WPS command is issued on
the group interface and there is no need to duplicate the event to
the parent interface.

d1b024c9e5 P2P: Make sure wpa_s->global->p2p_group_formation gets cleared
This pointer is now used in number of places to check whether an
interface is in P2P Group Formation, so we better make sure it gets
cleared when group formation has been completed. This was done in
only some of the cases.

9dd7d6b09c WPS: Add special AP Setup Locked mode to allow read only ER
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change then.
In other words, the protocol is allowed to continue past M2, but
is stopped at M7 when AP is in this mode. WPS IE does not
advertise AP Setup Locked in this case to avoid interoperability
issues.

In wpa_supplicant, use ap_setup_locked=2 by default. Since the AP PIN
is disabled by default, this does not enable any new functionality
automatically. To allow the read-only ER to go through the protocol,
wps_ap_pin command needs to be used to enable the AP PIN.

bb79dc720b P2P: Fix invitation-to-running-group handling
The pending_invite_ssid_id of -1 (running group, not persistent) was
being stored incorrectly in the group interface, not device interface
(i.e., parent of the group interface) and consequently, the incorrect
information was used when processing the Invitation Response.

If there was a persistent group credentials stored with network id
0, those were used instead to try to set up a persistent group
instead of using the already running group.

5496062919 P2P: Update pending join interface address during scans
Since the P2P peer entry may not have been available at the time the
join request was issued, we need to allow the P2P Interface Address
to be updated during join-scans when the P2P peer entry for the GO
may be added.

9b1ab931b1 P2P: Allow multiple scan runs to find GO for p2p_connect join
If the GO is not found, we cannot send Provisioning Discovery Request
frame and cannot really connect anyway. Since the Provisioning
Discovery is a mandatory part, it is better to continue join-scan
until the GO is found instead of moving to the next step where
normal connection scan is used (PD would not be used from there).

Use a limit of 10 scan attempts for p2p_connect join to avoid getting
in infinite loop trying to join. If the GO is not found with those
scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the
join attempt.

7cfc4ac319 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.

43882f1efc Allow TSN AP to be selected when configured for WEP
Commit d8d940b746 introduced a regression
that prevented TSN APs from being used with WEP since the AP was
rejected if it advertised WPA or RSN IE when we were configured to use
WEP. Resolve this by checking whether the AP is advertising a TSN, i.e.,
whether the AP allows WEP to be used as a group cipher. If so, allow
the AP to be selected if we are configured to use static WEP or
IEEE 802.1X (non-WPA).

It should be noted that this is still somewhat more restricted in AP
selection than earlier wpa_supplicant branches (0.7.x or older) that
ignore the WPA/RSN IE completely when configured for non-WPA.

09d660b9e3 P2P: Clear off_channel_freq when requesting new remain-on-channel

This removes extra latency from P2P Action frame operations
within a P2P group.

ae6e1bee67 Add WPA_IGNORE_CONFIG_ERRORS option to continue in case of bad config
This is an option to continue with wpa_supplicant and hostapd even if
config file has errors. The problem is that these daemons are the best
"candidates" for the config change, so if they can not start because
config file was let's say corrupted, you can not fix it easily.

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

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:
