21d996f775 P2P: Add support for preferred channel list
p2p_pref_chan configuration parameter can now be used to set the
list of preferred channel for P2P GO Negotiation. This will be used
in the priority order if the peer does not support the channel we
are trying to use as the GO (configured operating channel or the
best 2.4 GHz/5 GHz channel) for the case where a forced channel is
not used.

p2p_pref_chan=<op class:channel>,...

For example:
p2p_pref_chan=81:1,81:2,81:3,81:4,81:5,81:6

This would configure 2.4 GHz channels 1-6 as the preferred ones with
channel 1 the most preferred option.

These configuration parameters can be set in wpa_supplicant.conf and
dynamically updated with "wpa_cli set <param> <value>".

25f839c6d9 Filter station mode EAPOL RX on bridge interface based on destination
If multiple station mode radios are bridged together on the same device,
it is possible for wpa_supplicant to receive EAPOL frames from the
bridge interface and then process them separately for each interface.
This can results in problems since multiple instances of supplicant side
could end up trying to process a single 4-way handshake. Avoid this
problem by filtering bridge interface EAPOL RX based on the desctination
MAC address. It should be noted that this works only when unicast
addresses are used (e.g., with WLAN) and not with the IEEE 802.1X EAPOL
group address (e.g., most wired networks).

Commit 6bf731e8ce broke handling of
EVENT_CHANNEL_LIST_CHANGED by introducing a cached copy of the driver
channel list that does not get updated even if driver changes its list.
Fix this by synchronizing the cacched wpa_s->hw.modes information

ca29842700 dbus: revert changes to some peer properties
Commit 3f6e50ac28 made it possible to access
P2P peer properties using the org.freedesktop.DBus.Properties interface.

While maintaining the original intent of that patch we make two changes
to it here:

First, 3f6e50ac28 changed the type used to
represent the WPS vendor extension data from bytes to a string. In
addition to the type change the way in which the vendor extension data
was provided to the function creating the string was incorrect and would
not present the correct vendor extension data even in string format.

Revert the type change made in 3f6e50ac28
and present the WPS vendor extension data as an array of an array of
bytes as it was before.

Second, 3f6e50ac28 changes the secondary
device types representation from an array of an array of bytes to an
array of bytes. Revert that change to make secondary device types
accessible via an array of an array of bytes again.

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.

aa283ddd97 WPS: Do not use sched_scan for provisioning step
Normal scan is more reliable and faster for WPS operations and since
these are for short periods of time, the benefit of trying to use
sched_scan would be limited. This can fix WPS connectivity issues
with some drivers.

a565c23bf3 WPS: Fix regression in post-WPS scan optimization
Commit 3c85f144ce fixed issues with P2P
Action frame TX after disconnection by clearing wpa_s->assoc_freq.
This resulted in a regression to the post-WPS scan optimization that
used wpa_s->assoc_freq to enable fast single-channel scan. Fix this by
copying wpa_s->assoc_freq to a local variable before calling
wpa_supplicant_deauthenticate() that ends up calling
wpa_supplicant_mark_disassoc() which will clear assoc_freq.

f63b854215 P2P: Wait for PD-before-join response
Even though the Provision Discovery Response frame from PD-before-join
does not really provide any additional information, it can be better to
wait for it before starting the join operation. This adds a minimal
extra latency in the most common case and cleans up the sequence of
driver operations and debug log by avoiding potential processing of the
Provision Discovery Response while already running a scan for the actual
connection.

If transmission of Provision Discovery Request fails, join operation is
started without the additional wait. In addition, a new timeout is used
to start the join if Provision Discovery Response is lost for any
reason.

87343c2017 bgscan_simple: Refinements to fast-scan backoff
These changes account for situations where the CQM threshold
might be approximately the same as the currently received signal,
and thus CQM events are triggered often due to measurement
error/small fluctuations.  This results in scanning occurring
too frequently.

Firstly, inhibit the immediate scan when the short-scan count
is at the maximum.  This keeps bursts of CQM toggling from
causing a torrent of back-to-back scans.  This does not inhibit
immediate scans if the CQM triggers a second time (if the signal
falls lower past the hysteresis).  This reduces the scan rate in
the worst case (fast-rate toggling high/low CQM events) to the
short scan interval.

Secondly, change the behavior of the short scan count so it acts like
a "leaky bucket".  As we perform short-scans, the bucket fills until
it reaches a maximal short-scan count, at which we back-off and
revert to a long scan interval.  The short scan count decreases by
one (emptying the bucket) every time we complete a long scan interval
without a low-RSSI CQM event.

This reduces the impact of medium-rate toggling of high/low CQM
events, reducing the number of short-interval scans that occur before
returning to a long-interval if the system was recently doing
short scans.

0f4668ceac Try fallback drivers if global init for preferred drivers fails
Driver global init was considered a hard failure. Thus if, for example,
you used the Broadcom STA driver and didn't have nl80211 or cfg80211
loaded into the kernel, and specified a driver value of "nl80211,wext",
the nl80211 driver's global init would fail with the following message:

nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'

but since global init was a hard failure, creating the supplicant
interface would fail and the WEXT driver would not be tried.
Give other drivers a chance instead.

d93dfbd588 Delay scan request on select_network if disconnecting
The disconnection command results in disassociation and deauthentication
events which were previously processed during the scan in case of
select_network command being used while associated with another network.
While this works in most cases, it can result in confusing event
