Commit d9a38716cc did this for
hostapd_eapol_tx_status() but missed the older hostapd_tx_status()
path. Address that case, too.
The TX status event may be received after a station has been
disassociated in cases where the disassociation is following a
transmission of a Data frame. Ignore such events if the STA is not
associated at the moment the event is being processed. This avoids
confusing debug entries and rescheduling of the EAPOL TX timeouts for
STAs that are still in the STA table, but are not really in active EAPOL
session.

This fixes a corner case where a STA that has PMKSA cache entry (or
valid FT keys) could try to use full EAPOL/EAP authentication and fail.
If the STA will then try to use the still valid PMKSA cache entry (or
FT) before the STA entry has been cleared, authFail could have been left
to TRUE. That will make EAPOL authenticator PAE state machine enter HELD
state even though authSuccess was already forced to TRUE. This results
in the STA getting disconnected even though it should be allowed to
continue with 4-way handshake. While this is unlikely to happen in
practice, it is better to get this fixed by clearing authFail when
setting authSuccess.

While the exponential increase in the lockout period provides an
efficient mitigation mechanism against brute force attacks, this
additional trigger to enter indefinite lockout period (cleared by
restarting hostapd) will limit attacks even further by giving maximum of
10 attempts (without authorized user action) even in a very long term
attack.

When there is not enough entropy and there are two station associating
at the same time, one of the stations will be rejected, but during
that rejection, the "reject_4way_hs_for_entropy" flag gets cleared. This
may allow the second station to avoid rejection and complete a 4-Way
Handshake with a GTK that will be cleared as soon as more entropy is
available and another station connects.
This reworks the logic to ban all 4-way handshakes until enough entropy
is available.

Number of places in hostapd use ap_sta_disconnect() instead of
ap_sta_disassociate() or ap_sta_deauthenticate(). There are some
differences between these functions, e.g., in the area how quickly
the EAPOL state machines get deinitialized. This can result in
somewhat unexpected events since the EAPOL/WPA authenticator
state machines could remain running after deauthentication.
Address this by forcing EAPOL/WPA authenticator state machines
to disabled state whenever ap_sta_disconnect() is called instead
of waiting for the deauthentication callback or other timeout
to clear the STA.

Some deployed station implementations seem to send msg 4/4 with

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.

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

maximum inactivity timeout. This fixes some unexpected disconnection
cases with ath6kl in AP mode.

hostapd uses the poll method to check if the station is alive
after the station has been inactive for ap_max_inactivity seconds.
Make the poll mechanism configurable so that user can choose to
disconnect idle clients.
This can be especially useful when some devices/firmwares have
restrictions on the number of clients that can connect to the AP
and that limit is smaller than the total number of stations trying
to use the AP.

The 100 ms timeout on retransmitting group key message can be too short
for stations that are in power save mode or if there is a large number
of association stations. While the retransmission of the EAPOL-Key frame
should allow this to be recovered from, it is useful to avoid
unnecessary frames to save soem CPU and power.
