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.

current_bss and pending_bssid weren't cleaned up so BSS

Use wpa_supplicant_mark_disassoc() to cleanup the wpa_s context

Commit e4fb216769 moved frequency
storage from driver struct to bss struct and is assigned in
wpa_driver_nl80211_set_freq. As this wpa_driver_nl80211_set_freq is
triggered only on the first_bss, bss->freq for other BSSes is never
being set to the correct value. This sends MLME frames on frequency zero
(initialized value of freq) for BSSes other than the first.
To fix this derive frequency value from first_bss.

It looks like Windows 7 WPS implementation does not like multiple
Authentication/Encryption Type bits to be set in M7 AP Settings
attributes, i.e., it refused to add a network profile if the AP
was configured for WPA/WPA2 mixed mode and AP PIN was used to
enroll the network.
Leave only a single bit set in the Authentication/Encryption Type
attributes in M7 when the AP is acting as an Enrollee to avoid this
issue.

wpas_wps_in_use() was forcing WPS to be enabled unconditionally if P2P
support was included in the build. This is not really the correct
behavior for the case when P2P has been disabled at runtime. Change the
code here to verify runtime configuration of P2P before forcing WPS to
be enabled. This allows WSC IE to be left out from Probe Request frames
when scanning for APs without P2P or WPS being in use.

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.

The cookie value needs to be fetched in GO mode, too, to be able to
indicate TX status callbacks with drivers that handle AP mode SME
functionality internally. This fixes issues with client discoverability
where TX status callback for GO Discoverability Request is needed to
trigger the GO to send Device Discoverability Response.
When a P2P group is removed, we better not leave possibly started
sched_scan running. This could happen when a separate group interface
was not used.
In addition, it looks safer to explicitly stop sched_scan before
starting P2P Listen or Find operations to make sure the offloaded
scanning is not running when doing similar P2P operations.

This patch fixes an issue with roaming for drivers that set
WPA_DRIVER_FLAGS_BSS_SELECTION (currently ath6kl). On moving to an AP
with a different BSSID, an EVENT_ASSOC is received and the subsequent
4-way handshake may fail because of a mismatch between the RSN IE in
message 3/4 and in Beacon/Probe Response. This happens only when the APs
use different RSN IE contents and ap_scan is set to 1, since
wpa_supplicant fails to update its cached IEs.
Initial association may fail, too, in case of multiple APs with
the same SSID, since BSSID selection is done by the driver and again
a mismatch could be seen.
Fix these two issues by clearing and updating the cached IEs on
receiving an Association event from the driver. Also, retrieve the
scan results when the new BSS information is not present locally.

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

only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.

whether the event was generated locally.

IEEE Std 802.1X-2004 does not clear authWhile and heldWhile in this
case, but doing so allows the timer tick to be stopped more quickly when

actual state machine behavior. This reduces some unnecessary operations
in port disabled state and cleans up the wpa_supplicant debug log after
disconnection.
