e2197af1b2 P2P: Make sure parsed Device Name gets null terminated
If the msg->device_name buffer is filled from two different sources,
the copy from the P2P Device Info attribute needs to make sure that
the values gets null terminated to match the length of the correct
string should the other place use another string (which is not really
allowed by the spec, but could happen).

b73bf0a74b P2P: Stop connection attempt on PBC session overlap
The overlap condition cannot disappear before group formation timeout
hits, so there is no point in continuing in this case and failure can
be indicated immediately.

3094d4837a P2P: Use group formation timeout (but longer one) with join-a-group
This allows the pending group interface to be removed if we fail
to join a running group. A longer than 15 second timeout is needed
here since the GO may not have authorized our connection yet.

ae3e342108 P2P: Add peer timeout into group formation 15 second timeout
This adds some more time for WPS provisioning step in case the peer
takes long time to start group interface operations.

2f9929ffcc WPS: Allow pending WPS operation to be cancelled
A new ctrl_interface command, WPS_CANCEL, can now be used to cancel
a pending or ongoing WPS operation. For now, this is only available
with wpa_supplicant (either in station or AP mode). Similar
functionality should be added for hostapd, too.

fbe7027239 P2P: Provide local event on GO Neg Req rejection
If an authorized (p2p_connect used locally) GO Negotiation is
rejected when receiving GO Negotiation Request from the peer,
indicate the failure with a ctrl_interface P2P-GO-NEG-FAILURE
event. Previously, this event was only shown on the peer (i.e.,
the device receiving the GO Negotiation Response with non-zero
Status code).

014732ea81 WPS: Fix timeout event to be sent over ctrl_interface
This was supposed to be sent to external event monitors, i.e., to
use wpa_msg instead of wpa_printf.

ffe98dfb88 P2P: Process Invitation Request from previously unknown peer
Since this message now includes P2P Device Info attribute, it is
reasonable to learn the peer data and process the message instead of
rejecting the message.

c0a321c519 Allow bssid parameter to be cleared through ctrl_interface
Setting bssid to an empty string, "", or any can now be used to
clear the bssid_set flag in a network block, i.e., to remove bssid
filtering.

17bef1e97a P2P: Add peer entry based on Provision Discovery Request
Add (or complete Probe Request only) P2P peer entry when receiving
Provision Discovery Request from a previously unknown peer. This is
especially of use for a GO when a P2P client is requesting to join
a running group.

f8d0131a11 P2P: Use operating frequency from peer table as backup for join
The scan operation before Provision Discovery Request may not include
the GO. However, we are likely to have the GO in our P2P peer table,
so use that information to figure out the operating channel if BSS
table entry is not available.

f7a6905735 P2P: Add a workaround for Extended Listen Timing getting stuck
This should not really happen, but it looks like the Listen command
may fail is something else (e.g., a scan) was running at an
inconvenient time. As a workaround, allow new Extended Listen
operation to be started if this state is detected.

5548ddc217 P2P: Allow P2P IE without Device Info in (Re)Assoc Req
This can happen, e.g., when a P2P client connects to a P2P group
using the infrastructure WLAN interface instead of P2P group
interface. In that case, the P2P client may behave as if the GO
would be a P2P Manager WLAN AP.

10b9ac17cf P2P: For now, do not use channels 12-14 in P2P groups
This is needed to make sure we do not try to accidentally enable GO
in channels that may not be allowed. In addition, this may help with
some driver that do not like channel 14 even as a passive scan
channel.

eea2fd9eff P2P: Add mechanism for configuring UAPSD parameters for group
This is needed to be able to change parameters for dynamically
created interfaces between the creation of the interface and
association/start AP commands.

Following ctrl_interface commands can now be used:

P2P_SET client_apsd disable
- disable configuration (i.e., use driver default) in client mode

P2P_SET client_apsd <BE>,<BK>,<VI>,<VO>;<max SP Length>
- enable UASPD with specific trigger configuration (0/1) per AC
  (max SP Length is currently ignored)

P2P_SET go_apsd disable
- disable configuration (i.e., use driver default) in AP mode

P2P_SET go_apsd <0/1>
- disable/enable APSD in AP mode

5ded7d3eb8 P2P: Fix GAS fragmentation to match with IEEE 802.11u
P2P specification v1.15 fixed the description of the GAS fragmentation
to not duplicate NQP Query Response Field header in all fragments. This
change makes the fragmentation match with the description in IEEE
802.11u. The change is not backwards compatible with previous P2P
specification versions as far as fragmented SD responses are concerned.

uplink WLAN connection. This is disabled by default and can be
enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device
interface.

0af196088c P2P: Fix device discoverability to not wait before sending GO Neg Req

P2P_CONNECT_LISTEN state (short Listen mode) in this case.

is enabled whenever there are no non-P2P STAs connected to the GO.
