Use reason code 3 (Deauthenticated because sending STA is leaving)

more accurate reason for the message and allows the stations to get

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

not be disabled when P2P Listen state is stopped to avoid breaking AP
mode operations. This could happen, e.g., if a Probe Request frame was
received from a P2P device that the we are trying to invite to our group
(i.e., when operating in GO role). p2p_probe_req_rx() calls
p2p_invite_start() in this case and that ends up calling
p2p->cfg->stop_listen() which calls probe_req_report() driver op.

hostapd uses the poll method to check if the station is alive
after the station has been inactive for ap_max_inactivity seconds.
Make the poll mechanism configurable so that user can choose to
disconnect idle clients.
This can be especially useful when some devices/firmwares have
restrictions on the number of clients that can connect to the AP
and that limit is smaller than the total number of stations trying
to use the AP.

The P2P module provides access to public peer data in struct
p2p_peer_info. Use this to build the P2P_PEER information in
ctrl_iface.c instead of providing such text format data from the P2P

The internal data that was previously built in p2p_get_peer_info() as
part of the text format peer data is now available through a separate
p2p_get_peer_info_txt() function. This is still included in P2P_PEER
output to maintain backwards compatibility with external programs that
could have started to use this. However, it should be noted that this
data is not really supposed to be used for anything else apart from

When waiting for go_neg frame from the peer in WAIT_PEER_CONNECT state,
I have observed that sometimes it takes 20 to 30 secs for successful GO
negotiation. I also found out that it is because of 1 second idle time,
in WAIT_PEER_CONNECT state. While it is good to have 1 second idle time
[for doing power-save or doing some other legacy STA Scan or some other
useful stuff], this makes GO Negotiation process slow.
We wait for 1 second idle and then listen for a random time between
100(min)-300(max) ms. Assume P1 is in WAIT_PEER_CONNECT state and P2 is
the one which is now to send go_neg frame. If P2 sends GO Negotiation
frame just at the boundary of 300 ms of P1 and assume that P2 takes
close to 600-800 ms for one iteration of sending go_neg request (one
iteration is GO Negotiation Request frame time + dwell time +
listen_time), P2 needs to transmit at least 16-18 Action frames for
hitting the listen time of P1.
Following patch reduces the idle time to 500 ms. Alternatively we can
increase the listen time interval to 500 ms just for WAIT_PEER_CONNECT
state.
Provision discovery from a known peer should actually check for
dev->flags & P2P_DEV_PROBE_REQ_ONLY. This is creating an issue of
updating the listen frequency of peer with the PD request frame
frequency. PD request frame will be sent by the peer on our local listen
frequency. This patch fixes that error. Suggested check has already been
implemented in the invitation req receive path.
The Provision Discovery Request needs to be sent on the operating
channel of the GO and as such, the frequency from the BSS table
(scan results) need to override the frequency in the P2P peer
table that could be based on the Listen channel of the GO.

The GO negotiation response is very cryptic at the moment. For a success
message we only know on which interface the negotiation succeeded, not
which peer. For a failure we know the interface also and a status code
(number).
It will be very useful for clients to know upon receipt of such a message
which peer the negotiation occurred with.
Now that the peer information is available and the API is changed
already, the function composing the D-Bus message might as well include
all GO negotiation information. This is done with a dict to make things
easier on clients if this result information changes down the line.

Some client implementations only wait a few ms after sending a probe

leaves before all probe reponses where acked this can cause the probe
reponse to be retried quite often consuming even more airtime.
Hence, add a new noack flag to the driver's send_mlme callback that

Another niceness of OpenSSL is that if the high-order bit of a 521-bit
big num is not set then BN_bn2bin() will just return 65 bytes instead of
66 bytes with the 1st (big endian, after all) being all zero. When this
happens the wrong number of octets are mixed into function H(). So
there's a whole bunch of "offset" computations and BN_bn2bin() dumps the
big number into a buffer + offset. That should be obvious in the patch
too.
The previous EAP-pwd KDF implemented has an issue with group 21, that is
an elliptic curve group based on a 521 bit prime. 521 is not an even
multiple of 8, and therein lies the problem.
OpenSSL's BN library interprets a string of bits as in big-endian format
so all the calls of BN_bin2bn() will take the binary blob of bits and
turn it into a big number in big-endian format. In the EAP-pwd KDF, I am
stretching the key to "primebitlen". When that is not an even multiple
of 8 I have to mask off the excess. But I was masking off the excess
bits in the 1st octet (big endian after all) but that isn't right. The
KDF produces a string of endian-less bits. The 521st bit is the first
bit in the last octet, not the 7th bit in the first octet. So that has
been fixed and you can see in the attached diff what I'm doing.

"p2p_group_add" happens after legacy STA association, then this patch
will help to start the GO on the same frequency. This is useful when
supplicant is started on multiple interface running over a singly "PHY"
and the station interface is not used for the P2P device operations.
For example, wpa_supplicant -iwlan0 .. -N -iwlan1 ... and wlan0 is used
for station connection and wlan1 as the P2P device interface.

When GO negotation fails the WPS method is currently not cleared, which
can result in GO negotiation being resumed when a GO negotiation request

If P2P device expires while a GO Negotiation is in progress, currently
p2p->go_neg_peer is cleared without indicating GO Nego failure. This
will result in pending group interfaces to be left over. This patch will
indicate GO Negotiation failure and will remove any pending group
interfaces.
This patch addresses a corner case in GO-Negotiation case. Consider the
scenario where two devices A and B are in discovery stage and Device B
vanishes [moves out of range] when a connect is issued on the Device A.
Then Device A keeps on retrying the GO Negotiation Request till the
retry limit is reached. On reaching retry limit, the pending group
interface is removed. But suppose if the peer entry in the device list
expires before the retry limit is reached, then pending group interface
was not removed.

Instead of hardcoding IEEE 802.11b rates to be disabled whenever
P2P support is built in and supported by the driver, do this only

enabled rates at the end of the deinit operations when the interface
type was forced back to station. Both of these issues are now fixed

The netlink event processing is delayed since they are only returned
after control returns to eloop. This can result in netlink down events
being processed at a point when the interface has is actually still
there (the first event on new interface is down) and that can result in
odd behavior especially when the resulting interface-disabled event is
delivered to AP mode interface with wpa_supplicant.
Work around this by filtering netlink down events if the matching
interface is up at the time the netlink event is processed. This fixes
an issue brought up by commit 36d84860bb.
hostapd_wpa_auth_conf() is called on uninitialized memory and the
conditional blocks in this function may leave some fields into
uninitialized state. This can result in unexpected behavior elsewhere
since some of the variables may be used without matching #ifdef
blocks. Fix this by zeroing the memory.

For P2P, the p2p_connect takes in device address argument to make a
connection. However the connected event AP-STA-CONNECTED comes with
interface address. The application listening on events would find it
difficult to map interface address to the p2p device address which is
provided for connection.
Append P2P Device Address to AP-STA-CONNECTED event for P2P Client
connection. This will help applications to easily map the P2P Interface
Address to P2P Device Address on CONNECTED event. For non-P2P case, it
will just print the usual STA MAC address alone.
