IEEE Std 802.1X-2004 does not clear authWhile and heldWhile in this
case, but doing so allows the timer tick to be stopped more quickly when
the port is not enabled. Since these variables are used only within HELD
and RECEIVE states, clearing them on initialization does not change
actual state machine behavior. This reduces some unnecessary operations
in port disabled state and cleans up the wpa_supplicant debug log after
disconnection.

The authentication timeout could be triggered after the connection has
already been known to have failed. The event at that point can be
confusing, so better cancel the timeout when processing connection
failure.

The offchanok parameter is hardcoded to one in number of paths and that
added NL80211_ATTR_OFFCHANNEL_TX_OK attribute to NL80211_CMD_FRAME
unconditional. cfg80211 rejects this with EINVAL if the driver does not
indicate support for offchannel TX. Fix this by not requesting
offchannel TX depending on driver capabilities. Remain-on-channel
operation was used for those cases anyway, so the additional attribute
was not really needed for these in the first place.

When nl80211_setup_ap() has enabled Probe Request reporting, this must
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
debugging purposes and its format is subject to change.

If the driver was associated in station mode just before the AP mode was

If p2p_listen is issued during a p2p_scan, a pending after-scan operation

The p2p_group_idle configuration parameter is much more useful for
GO role, so use a separate hardcoded value of 10 seconds in P2P
client role. In practice, this means that the P2P client role will
automatically tear down the group when the GO tears down the group.
The 10 second timeout is enough to recover from temporary disconnections
without unnecessary tearing down the group if the GO is still present
and allows the client to connect.

When P2P client is processing a disconnection event, make sure the P2P
idle timeout does not get increased, i.e., set a new timeout only if no

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
the device sees itself. It is related to lack of filtering itself from

2. dev2: p2p_connect <MAC1> pbc join
3. dev1: wps_pbc
