9f12614b8c nl80211: Do not encrypt IEEE 802.1X WEP EAPOL
Set the NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag for nl80211 to tell
drivers (mac80211) to not encrypt the EAPOL frames for WEP IEEE 802.1X.

204dd3f420 EAP server: Force identity request after INITIALIZE for passthrough
Previously, sm->start_reauth was set to TRUE in SUCCESS2 state to force
reauthentication to start with EAP identity request. This works fine for
the case of EAP success through the AAA passthrough authentication, but
is not enough to handle passthrough authentication failure. sm->identity
is set in that case and getDecision would return PASSTHROUGH instead of
CONTINUE (to Identity method).

f98eb880eb Update RSN supplicant MAC address on driver reinitialization
I have a test case where I remove and insert another network adapter
between two connections to AP. The interface get the same interface name
but switches macadresses between the connections. When running WPA2 I
got a failure in EAPOL negotiation and found out that the reason for
this was that the supplicant did not update the MAC address in the
correct place.

c0f83f3104 WPS: Disable WPS(v2) in WPA/TKIP-only configuration
When using wpa_supplicant AP mode, WPS support is enabled by default for
WPA/WPA2-Personal. Change this to enforce the WPS2 rules on not allowing
WPS to be used with WPA/TKIP-only configuration (i.e., at minimum, mixed
mode with WPA/TKIP and WPA2/CCMP has to be used for WPS to be enabled).

56d24b4ee0 Call wpas_connection_failed() only if actually trying to connect
A disconnection event from the driver may end up getting delivered at a
time when wpa_supplicant is not even trying to connect (e.g., during a
scan that was already started after WPS provisioning step). In such a
case, there is not much point calling wpas_connection_failed() and
skipping this avoids confusing attempts of re-starting scanning while
the previous scan is still in progress.

a9e02d593d P2P: Clear show_group_started on GO start
The show_group_started variable could be left to 1 based on an earlier
failed attempt to start P2P client operation. This can result in
unexpected P2P-GROUP-STARTED event when a GO is started without group
formation (e.g., re-invoke a persistent group or start an autonomous
GO). Avoid this by explicitly clearing show_group_start when setting up
the GO.

910b482d9b WPS: Fix stopping of active WPS operation on dual concurrent AP
When hostapd controls multiple radios, WPS operations are started on
all interfaces. However, when the provisioning run had been completed
successfully, actiove WPS mode was stopped only a single interface. Fix
this to iterate through all interfaces so that this is handled
consistently with the starting of WPS operation.

d6d731b848 WPS ER: Fix segfault in some selected registrar change cases
Commit 628d54639a introduced number
of new WPS related ctrl_iface messages to hostapd. Some of these
were for ER events which do not make any sense to hostapd that
cannot operate as an ER. The WPS_EV_ER_SET_SELECTED_REGISTRAR one
from wps_registrar_sel_registrar_changed_event() was especially
problematic since it can cause wpa_supplicant ER code segfault due
to missing event data.

Revert all the ER specific changes from commit
628d54639a to get rid of the segfault
and undesired extra code in hostapd.

ea5bae4731 Increase min sched_scan interval from 2 to 10 seconds
Trying to run sched_scan round every two seconds by defaults sounds way
too frequent since dualband cards are unlikely to be able to complete
the full scan cycle in two seconds. For now, set the hardcoded value to
10 seconds to make this somewhat more reasonable.

0b7a25c00f Use normal scan before sched_scan if that can speed up connection
When normal scan can speed up operations, use that for the first three
scan runs before starting the sched_scan to allow user space sleep more.
We do this only if the normal scan has functionality that is suitable
for this or if the sched_scan does not have better support for multiple
SSIDs.
