Stop AP command can be used by the driver as an event to indicate that
AP mode has stopped operation. WLAN driver may have encountered errors
that has forced the driver to report this event or concurrent operations
on virtual interfaces may have forced AP operation to be stopped. When
in P2P GO mode, wpa_supplicant uses this event to remove P2P group to
keep in sync with the driver state.

This reverts commit ce970851af.
It turned out that this breaks lots of use cases where p2p_find is
issued while already in p2p_listen state. As such, we cannot reject
p2p_find this easily without checking for more specific cases.
Signed-hostap: Jouni Malinen <j@w1.fi>
Though p2p_find is not expected during ongoing P2P connection, it is
possible that any third party application issues a p2p_find resulting in
connection failure. Address this by rejecting any p2p_find command while
connection is in progress.

A transmission failure of the TDLS Setup Request frame (TPK Handshake
M1) results in no further retries and the peer entry being left in state
where all TDLS Setup Request frames from the peer with higher address
would be rejected, thus always resulting in a failure to establish a
TDLS link. Handle the failures in transmission by disabling the link
immediately to ensure the traffic to the peer goes through the AP. This
commit also handles similar transmision failures for TPK Handshake M2
and M3 frames (TDLS Setup Response and Confirm).

4-way handshake may fail under extremely noisy environment and if this
happens during P2P group formation, the 10 second extra delay added in
wpas_auth_failed() can result in running over the 15 second timeout.
Avoid this by skipping the delay mechanism in wpas_auth_failed() for the
P2P group formation case. The P2P formation timeout will take care of
stopping the attempts if the failure condition does not get resolved.

The nl80211 command for setting the TX index does not distinguish TDLS
vs. AP key and as such, the driver would not know what this set TX key
index operation is doing in the TDLS case. This could result in the TX
key index for AP being changed instead if static WEP is used in the AP
connection. Fix the issue by not setting TX key index when configuring a
TDLS key.

There are devices that can operate several channels concurrently.

To better support the IBSS/RSN mechanism, wpa_supplicant has to be able
to detect a possible peer reboot and in this case it should start a new
EAPOL handshake.
To perform such reboot detection wpa_supplicant has to perform an Open
Authentication by sending an Authentication frame and then replying to
it. IF an Authentication frame is received when the key have already
been exchanged, wpa_supplicant understands that the peer has rebooted
and can reset its state machine.
Whenever a new peer is added to the IBSS wpa_supplicant will start the
Open Authentication and only after having accomplished it will start the
key exchange. If the driver does not support Authentication frame
exchange initiated from user space, this step is skipped to maintain
previous behavior (just go through EAPOL-Key frame processing).
The Open Authentication was partly supported by the Linux kernel but now
wpa_supplicant can register for Authentication frames, handle it in
userspace and so avoid any possible race condition.

This allows wpa_supplicant to associate to an AP that has VHT BSS

In a AP/STA concurrent setup, if the STA interface is continually
scanning, trying to connect to a network, the AP interface
is basically broken since beaconing would be erratic.
This option can be used in a WDS setup where one AP acts as a
Client/AP-Repeater. The Repeater AP interface has to start beaconing
only after the Client interface has established a WDS link with the
"Root AP".

Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.
This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same
behavior.

It looks like some of the global control interface cases ended up

3GPP TS 24.232 Annex A.3 allows network operator to advertise only two
digits of MNC even if MNC has three digits. Allow such matches in
network selection. In addition, allow three digit matches of MNC even if
MNC length was assumed to be two to avoid missing networks if MNC length
cannot be determined reliably. Remove the '-' separator from simulated
SIM/USIM cases to allow the new matching rules to work.
Fix the PLMN List information element parsing loop to use the length of
the PLMN List instead of the length of the full 3GPP Cellular Info to
avoid unexpected matches should a new element ever be added by 3GPP.
