If p2p_listen is issued during a p2p_scan, a pending after-scan operation
is scheduled. However, since there is support for only a single pending
operation, this was able to override a previously scheduled pending
connect command. This can break some command sequences, so give higher
priority to pending connect operation.

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.

When the station is connected to P2P GO after calling p2p_find command

WPS overlap detection can detect false overlap if a P2P peer
changes UUID while authentication is ongoing. Changing UUID
is of course wrong but this is what some popular devices do
so we need to work around it in order to keep compatibility
with these devices. There already is a mechanism in WPS
registrar to skip overlap detection if P2P addresses of two
sessions match but it wasn't really triggered because the
address wasn't filled in in the caller function.
Let's fill in this address and also clean up WPS PBC sessions
on WSC process completion if UUID was changed.

them on the per-BSS event socket.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
To achieve this, multiple things are needed:
1) since hostapd needs to handle *all* action frames,
make the normal registration only when in a non-AP
mode, to be able to do this use the new socket
2) store the frequency in each BSS to be able to give
the right frequency to nl80211's mgmt-tx operation
3) make TX status processing reject non-matched cookie
only in non-AP mode
The whole thing depends on having station-poll support
in the kernel. That's currently a good indicator since
the kernel patches are added together.
