WPS: Fix clearing of SetSelectedRegistrar with multiple interfaces
The SetSelectedRegistrar timeout was registered for each registrar

In addition, when an ER unsubscribed from receiving events, the

bgscan_simple: Refinements to fast-scan backoff
These changes account for situations where the CQM threshold
might be approximately the same as the currently received signal,
and thus CQM events are triggered often due to measurement
error/small fluctuations. This results in scanning occurring
too frequently.
Firstly, inhibit the immediate scan when the short-scan count
is at the maximum. This keeps bursts of CQM toggling from
causing a torrent of back-to-back scans. This does not inhibit
immediate scans if the CQM triggers a second time (if the signal
falls lower past the hysteresis). This reduces the scan rate in
the worst case (fast-rate toggling high/low CQM events) to the
short scan interval.
Secondly, change the behavior of the short scan count so it acts like
a "leaky bucket". As we perform short-scans, the bucket fills until
it reaches a maximal short-scan count, at which we back-off and
revert to a long scan interval. The short scan count decreases by
one (emptying the bucket) every time we complete a long scan interval
without a low-RSSI CQM event.
This reduces the impact of medium-rate toggling of high/low CQM
events, reducing the number of short-interval scans that occur before
returning to a long-interval if the system was recently doing
short scans.

P2P: Notify upper framework on stopping the p2p_find(SEARCH)
This patch notifies the upper framework that an on-going discovery has
been stopped. This is useful in cases where a p2p_find with a timeout
value initiated by the upper framework has been finished or when the
framework initiated "p2p_find" is stopped by a "p2p_connect".

Work around interop issue with WPA type EAPOL-Key 4/4 in WPA2 mode
Some deployed station implementations seem to send msg 4/4 with
incorrect type value in WPA2 mode. Add a workaround to ignore that issue
so that such stations can interoperate with hostapd authenticator. The
validation checks were added in commit f8e96eb6fd960a017793942cff0eb43b09f444c6.

P2P: Use Device ID attribute to filter Probe Request frames as GO
The Device ID attribute was already used in Listen state, but it was
ignored in GO role. Verify that there is a match with Device ID in
GO rule, too, before replying to the Probe Request frame.

Allow SNonce update after sending EAPOL-Key 3/4 if 1/4 was retransmitted
Some supplicant implementations (e.g., Windows XP WZC) update SNonce for
each EAPOL-Key 2/4. This breaks the workaround on accepting any of the
pending requests, so allow the SNonce to be updated even if we have
already sent out EAPOL-Key 3/4.
While the issue was made less likely to occur when the retransmit
timeout for the initial EAPOL-Key msg 1/4 was increased to 1000 ms,
this fixes the problem even if that timeout is not long enough.

Do not disconnect STA based on inactivity on driver failure
Now that we can use driver_nl80211.c with non-mac80211 drivers that
implement SME/MLME internally, we may not get inactivity time from the
driver. If that is the case, we need to skip disconnection based on
maximum inactivity timeout. This fixes some unexpected disconnection
cases with ath6kl in AP mode.

Do not trigger fast reconnection on locally generated deauth/disassoc
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.
Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.
