ace0fbdb69 P2P: Fix segfault when PBC overlap is detected
If a separate P2P group interface is used, PBC overlap during group
formation causes the group interface to be removed, which ends up with
the interface context becoming invalid. Fix this by scheduling a timeout
to process the PBC overlap and interface removal instead of removing the
interface directly before the connection operation has returned.

60b893dfb3 wpa_supplicant: Allow external management frame processing for testing
This enables more convenient protocol testing of AP and P2P
functionality in various error cases and unexpected sequences without
having to implement each test scenario within wpa_supplicant.
ext_mgmt_frame_handle parameter can be set to 1 to move all management
frame processing into an external program through control interface
events (MGMT-RX and MGMT-TX-STATUS) and command (MGMT_TX). This is
similar to the test interface that was added to hostapd previously, but
allows more control on offchannel operations and more direct integration
with the internal P2P module.

7c373ac267 Interworking: Fix last-network preference to not override priority
Commit 3d910ef497 tried to make
last-network selection behave more consistently with Interworking
network selection preferences. However, it did not take into account
that other network block may have higher priority. In such cases, the
last added network from Interworking network selection should actually
not be selected for the next connection. Fix this by limiting the
last-network preference to work only within a priority class.

3d910ef497 Interworking: Prefer last added network during network selection
Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

b3253ebb73 wpa_supplicant: Complete radio works on disable event
While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.

Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.

To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

253f2e3795 P2P: Apply unsafe frequency rules to available channels
This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.

If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

cf70d2981d wpa_supplicant: Schedule PNO on completion of ongoing sched_scan
When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.

In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.

dd271857a5 Skip normal scan when PNO is already in progress
Scan request failures are observed in wpa_supplicant debug log when
Android framework starts PNO scan in driver via ctrl interface command
'set pno 1' and wpa_supplicant also tries to issue a scan request after
PNO has started in the driver.

Some drivers may reject a normal scan request when PNO is already in
progress. wpa_supplicant should consider PNO status before issuing start
scan request to the driver. Otherwise, wpa_supplicant will get failures
from driver for the scan request and it will end up rescheduling scan
request in periodic interval and get a start scan request failure for
each attempt.

In order to avoid unnecessary scan attempt when PNO scan is already
running, PNO status is checked before issuing scan request to driver.

a0e9d89203 Use minimal scan delay upon EVENT_INTERFACE_ADDED
This patch resets the static interface_count to zero in case of
wpa_supplicant_driver_init() call for wpa_s which is in
INTERFACE_DISABLED state. This interface_count is used for the delay of
the scan which is now minimal for dynamically added interfaces. This may
collide with a scan for another interface, but the same is true for any
chosen delay in this scenario. Also the state change to DISCONNECTED is
moved to wpa_supplicant_driver_init() so it will move from
INTERFACE_DISABLED to INACTIVE when there are no enabled networks.

6f72577f29 P2P: Handle INTERFACE_DISABLED event on a P2P GO interface
An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.

The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

1245503188 Restore scan_req if sta scan is rescheduled in the scan results event
On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).

If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
	=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.

This patch fixes this issue by restoring the previous scan_req value.

731ca6364e Update regulatory change to all virtual interface for the phy
wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.

change events to all of the virtual interfaces sharing the same phy for
which the event is received.
