Commit 05ab9712b9 added support for
fetching WPA PSK from an external RADIUS server and changed
hostapd_wpa_auth_get_psk() to always return the RADIUS supplied PSK (if

appending the RADIUS supplied PSK to the list iterated by
hostapd_get_psk and thus returning NULL when prev_psk == sta->psk

There is a race condition in GO Negotiation Request frame sending and

Fix this by ignoring GO Negotiation Response from the peer if twe have
already sent a GO Negotiation Response frame and we have the higher P2P
Device Address. This is similar to the rule used to determine whether to
reply to GO Negotiation Request frame when Request was already sent,

Resolve this race by incrementing go_neg_req_sent when p2p_send_action()

This was previously indicated as disassociation, but the P2P group
session ending case expect a deauthentication notification. Since the
cfg80211 disconnection event does not really indicate which frame was
used, the easiest approach for now seems to be to just indicate these
as deauthentication events.

Use reason code 3 (Deauthenticated because sending STA is leaving)
instead of reason code 2 (Previous authentication ot valid) in the
Deauthentication frame sent at the time a BSS is terminated. This is
more accurate reason for the message and allows the stations to get
better understand on why they were disconnected. This can be useful
especially for P2P clients that can use this as a signal that the
P2P group session was ended per P2P specification section 3.2.9.

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.

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.

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.

When hostapd is about to start an AP using HT40, it starts a scan to
check whether it is allowed or not. If OLBC is detected before the
scan has completed, it sets the beacons prematurely.
To fix this, instead of setting all beacons when OLBC is detected,
only update the ones that have already been started.

ieee802_1x_encapsulate_radius() frees the RADIUS message if
radius_client_send() returns error. This could have resulted in use of
freed memory and double freeing of the RADIUS message if send() fails
since the message is also left in the retransmit list. Avoid this by not
returning error to the caller in such a case.

Add the option (-T) to wpa_supplicant to log all debug messages into the
kernel tracing, allowing to aggregate kernel debugging with
wpa_supplicant debugging and recording all with trace-cmd.
Since tracing has relatively low overhead and can be filtered
afterwards, record all messages regardless of log level. However, it
will honor the -K option and not record key material by default.

The "BSS p2p_dev_addr=address" command uses p2p_parse_dev_addr() to
figure out the P2P Device Address of the GO from scan results. This used
to work only if the P2P IE was received from Probe Response frames since
only those include the P2P Device Info attribute. Make this work with
Beacon frames, too, by using P2P Device ID attribute if the P2P Device
Info attribute is not present.

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>".

When drivers advertise their capability to free up inactive
stations based on ap_max_inactivity, send the inactivity period
timeout to driver in NL80211_ATTR_INACTIVITY_TIMEOUT. This
introduces a WPA_DRIVER_FLAGS (WPA_DRIVER_FLAGS_INACTIVITY_TIMER)
so that the inactivity period will be sent only when this capability
bit is set.

When the driver (or firmware) implements AP mode SME, the use of raw
management frame TX functions is not working properly at the moment. As
an initial step, convert these AP mode operations to use
NL80211_CMD_DEL_STATION and do not claim that driver provides TX status
for deauth/disassoc frames. While this does not address all use cases
(e.g., reason code is not specified in the command), this fixes number
of issues where the station does not get disconnected properly.

Commit 30680e9332 changed the length
of the implicit challenge result to match with the exact length used
in TTLS. However, it failed to update the peer_challenge generation
to use a separate random value. Previously, this was generated as
part of the implicit challenge, but more correct way would have been
to generate a random value for it separately. Do this now to fix the
read after the allocated buffer (16 bytes after the implicit
challenge).

Previously, this provisioning info was cleared using the P2P Interface
Address of the GO as the key. That did not always work in the case the
where we joined an already running group. This could result in the next

finding the peer entry based on its P2P Device Address instead of the
P2P Interface Address which may not always be set.

Use Device Password ID in WSC IE of Probe Request and Probe Response
frames to advertise immediate availability of WPS credentials per P2P
specification sections 3.1.2.1.1 (Listen State), 3.1.2.1.2 (Scan Phase),
and 3.1.2.1.3 (Find Phase).
For now, the Device Password ID is set only for the case where we are
active GO Negotiation with a specific peer. In practice, this means that
the Probe Response frames during pending GO Negotiation (whenever in
Listen state) indicate availability of the credential.

p2p_flush did not explicit stop all P2P operations, i.e., the exact

If Listen state was in progress on another channel when a request to
send an Action frame (e.g., Provision Discovery Request or Invitation
Request to a peer on the peer's Listen channel that is different from
our Listenc hannel) is issued, wpa_supplicant tried to use concurrent
remain-on-channel operations. While some drivers can handle this
cleanly, there are drivers that don't and wpa_supplicant is not expected
to request concurrent remain-on-channel operations.
Fix this by cancelling the ongoing remain-on-channel with stop_listen
prior to sending the Action frame on another channel. If a P2P search
was in progress, it will be continued after the timeout on the new
operation.

Definition of ANonce selection in IEEE Std 802.11i-2004 is somewhat
ambiguous. The Authenticator state machine uses a counter that is
incremented by one for each 4-way handshake. However, the security
analysis of 4-way handshake points out that unpredictable nonces help in
preventing precomputation attacks. Instead of the state machine
definition, use an unpredictable nonce value here to provide stronger
protection against potential precomputation attacks.
