f05b6b18bb Add script to convert wpa_supplicant debug output to pcap
For debugging I needed to look at the frames in a wpa_supplicant debug
log. Looking at the hexdump is a bit tedious, so I wrote a quick script
to convert the nl80211 debugging output to a PCAP file that can be
opened in wireshark.

I've polished the initial raw script a bit to add error messages and to
also record the timestamps to the pcap file.

Hopefully it's useful to somebody else as well.

3fc14102f8 P2P: Remove client group on Deauthentication reason code 3
The GO can indicate that the P2P Group session is ending by sending a
Deauthentication frame with reason code 3 (Deauthenticated because
sending STA is leaving) based on P2P specification section 3.2.9. Use
this reason code to remove the P2P client group without waiting for the
group idle timeout.

3c29244eb7 P2P: Add deinit_p2p_cli op to clear P2P client driver state
On P2P group removal, the GO is deinitialized correctly (and the vif
mode is set back to sta in case of nl80211), but the P2P client mode
wasn't deinitialized, and the nl80211 vif stays in P2P client mode.

Add a new deinit_p2p_cli op (similar to deinit_ap), which currently only
sets the interface back to station mode.

2d43d37ff2 DBus: Add ability to report probe requests
Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify
non-P2P peers (P2P peers are identified via PeerFound signals).

As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.

A small test script is also included.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.

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.

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).

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.

A list of disallowed frequencies for P2P channel list can now be
configured with P2P_SET disallow_freq. The frequencies (or frequency
pairs) are comma separated. For example:
wpa_cli p2p_set disallow_freq 2462,5000-6000

The allowed P2P channel list is constructed by removing explicitly
disallowed channels from the channel list received from the driver.

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.
