3379a3a795 WPS: Fix Beacon WPS IE on concurrent dualband AP in PBC mode
The Beacon frame must include UUID-E and RF Bands attributes when
in active PBC mode to allow stations to figure out that two BSSes in
PBC mode is not a PBC session overlap.

ff28ccafd5 WPS: Add BSSID to strict validation error messages
This makes it easier to figure out which AP is sending invalid
Beacon or Probe Response frames.

e0369e3664 WPS: Use same UUID in multi-interface case
When generating the UUID based on MAC address, share the same UUID
with all interfaces. This fixes a potential issue with concurrent
dualband APs where the UUID needs to be same for PBC to work properly.

7736f18bef WPS: Cancel WPS operation on PBC session overlap detection
Previously, wpa_supplicant remaining in scanning state without
trying to connect, but there is no particular need to do that.
Instead, cancel WPS operation completely whenever PBC session
overlap is detected.

This adds an initial EAP-pwd (RFC 5931) implementation. For now,
this requires OpenSSL.

ea184114ca Allow auto-connect to request scan in associating state
Disconnection event may be received while in associating state.
Previously, wpa_supplicant could get stuck not trying to reconnect
in that case at least with nl80211. Allow scan request in this
state to avoid the issue. This helps especially with APs that do
load balancing by sending Deauthentication frame as a response to
Reassociation Request frame after successful Authentication frame
exchange.

0f66abd25b P2P: Add option for disabling intra BSS distribution
p2p_intra_bss configuration parameter can now be used to
disable/enable intra BSS distribution (bridging of frames between
the clients in a group).

0d0a8ca1cc Add option for disabling automatic reconnection on disconnection
ctrl_interface STA_AUTOCONNECT command can now be used to disable
automatic reconnection on receiving disconnection event. The default
behavior is for wpa_supplicant to try to reconnect automatically, i.e.,
to maintain previous behavior.

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.

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).

filtering.

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.

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.
