be5ab8d4ab D-Bus: Add InvitationReceived Signal
This is equivalent to the P2P_EVENT_INVITATION_RECEIVED signal on the
control interface. It can be used to sent the Invitation Received signal
to applications written using D-Bus.

c9cfa6a9af Android: Avoid same per-iface and global ctrl socket
Android platform assigns the same socket id if the socket identifier in
conf->ctrl_interface and global->params.ctrl_interface (parameter for
android_get_control_socket) point to the same Android specific control
socket. This ends up having two eloop socket handlers registered for the
same file descriptor and thus, two attempt to receive and process each
command. This can result in unexpected failure, e.g., the prefix IFNAME=
for any command is valid for global socket handler, but results in
UNKNOWN COMMAND response from the per-interface ctrl socket handler).

Since it might be possible to end up with this type of invalid
configuration in OTA upgrade, compare the socket identifiers and do not
open the ctrl socket on the respective interface if both point to same.
This allows the Wi-Fi framework to use the global control interface.

5a1d9d1a8e Avoid reconnection on ENABLE_NETWORK if already connected
This was already the case for most command sequences, but it was
possible for wpa_s->reassociate to be set to 1 when CTRL-RSP-* commands
were used to set identity, password, or passphrase for EAP
authentication. In such cases, ENABLE_NETWORK issued after the
connection was completed could result in a new connection attempt
(likely reconnection back to the same BSS).

Fix this by checking whether an actual connection is already present
even if wpa_s->reassociate is set when processing the ENABLE_NETWORK
command.

ce7d0eb184 Update AP WPA/RSN IE on all associations if driver can select BSS
It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.

Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
BSS.

dfaf11d648 P2P: Require fresh scan results for persistent group re-invocation
The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.

Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

b9da88d6c1 P2PS: Authorize any peer for P2PS method if interface address not known
When P2PS PD with default P2PS method is done, the peer that becomes GO
should authorize the client. However, P2PS specification doesn't require
the client to include its intended interface address in PD
Request/Response. As a result, the P2P Client's interface address may not
be known and any address may need to be authorized.

Previously, client's P2P Device Address was used for authorization,
which is not correct when a dedicated interface is used for P2P Client.
This is not resulting in a connection failure, however it causes a
significant delay (until WPS_PIN_TIME_IGNORE_SEL_REG elapses). Fix this
by authorizing the intended interface address, if known; or any address,
if not known.

93f22b4583 P2PS: Fix PD PIN event notifications
Change P2PS P2P-PROV-SHOW-PIN/P2P-PROV-ENTER-PIN event notifications
on PD Request/Response handling to meet required P2PS behavior.

The new implemented scheme:
1. For a legacy P2P provision discovery the event behavior remains
   without changes
2. P2PS PD, advertiser method: DISPLAY, autoaccept: TRUE:
   Advertiser: SHOW-PIN on PD request replied with a status SUCCESS
   Seeker: ENTER-PIN on PD response received with a status SUCCESS
3. P2PS PD, advertiser method: DISPLAY, autoaccept: FALSE:
   Advertiser: SHOW-PIN on PD request replied with a status
     INFO_CURRENTLY_UNAVAILABLE
   Seeker: ENTER-PIN on Follow-on PD request with a status
     SUCCESS_DEFERRED
4. P2PS PD, advertiser method: KEYPAD, autoaccept: TRUE/FALSE:
   Advertiser: ENTER-PIN on PD request replied with a status
     INFO_CURRENTLY_UNAVAILABLE
   Seeker: SHOW-PIN on PD response received with a status
     INFO_CURRENTLY_UNAVAILABLE

This change in behavior breaks the existing test cases
p2ps_connect_keypad_method_nonautoaccept and
p2ps_connect_display_method_nonautoaccept. Those will be fixed in a
followup commit.

dae4c82c95 P2P: Disallow GO CS immediately after GO Negotiation or invitation
A newly created GO might move to another channel before the client was
able to connect to it. This creates a situation where the client
searches the GO on the channel agreed upon during GO Negotiation or
invitation signaling, while the GO is on another channel. This in turn
might lead to delayed connection or connection failure and group
removal.

Fix this by disallowing a GO CS as long as there is some activity that
should delay the switch. If a GO move is not allowed, set a timeout to
re-attempt the move.

1a471ff081 P2P: Move a GO from its operating frequency
Upon any change in the currently used channels evaluate if a GO should
move to a different operating frequency, where the possible scenarios:

1. The frequency that the GO is currently using is no longer valid,
   due to regulatory reasons, and thus the GO must be moved to some
   other frequency.
2. Due to Multi Concurrent Channel (MCC) policy considerations, it would
   be preferable, based on configuration settings, to prefer Same
   Channel Mode (SCM) over concurrent operation in multiple channels.
   The supported policies:

   - prefer SCM: prefer moving the GO to a frequency used by some other
     interface.
   - prefer SCM if Peer supports: prefer moving the GO to a frequency
     used by some other station interface iff the other station
     interface is using a frequency that is common between the local and
     the peer device (based on the GO Negotiation/Invitation signaling).
   - Stay on the current frequency.

Currently, the GO transition to another frequency is handled by a
complete tear down and re-setup of the GO. Still need to add CSA flow to
the considerations.

ecd40fef74 mesh: Fix mesh SAE auth on low spec devices
The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.

After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).

On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().

So this patch makes the default to 1000(msec) and makes it configurable.

This issue does not occur on infrastructure SAE because the
dot11RSNASAERetransPeriod is not used on it.

information over such temporary disconnections and only remove it on
