eb6f8c2bd4 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
incorrectly the P2P client supplicant instance will crash as a result
of cleanup happening on data that is still in use in a case where a
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.
The way we're cleaning up and deleting data from under ourselves here
just isn't safe, so make the teardown portion of this async.

c772ef43f6 P2P: Update BSS entries in P2P group interface only if P2P IE is present
For concurrency scenarios we should not update the scan results without
P2P IE to P2P group interfaces. This patch is to take care if a scan has
been requested on STA interface and scan results are getting updated
from sibling to P2P group interface. A P2P GO Probe Response for a
legacy STA scan would be without P2P IE. So it will wrongly update the
BSS list of P2P group interface too when results are updated from
sibling.

Since P2P group interfaces are used only for connecting to a P2P group,
it is fine to filter out all non-P2P entries from their BSS table.

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.

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

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.

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).
