a12d34546a wpa_supplicant: Use monotonic time for last_scan check
This just serves to check if there was a scan within
the last 5 seconds, hence it should use monotonic time.
While at it, also use os_reltime_expired().

6f72577f29 P2P: Handle INTERFACE_DISABLED event on a P2P GO interface
An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.

The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

1245503188 Restore scan_req if sta scan is rescheduled in the scan results event
On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).

If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
	=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.

This patch fixes this issue by restoring the previous scan_req value.

731ca6364e Update regulatory change to all virtual interface for the phy
wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.

To resolve this issue, update channel list information on regulatory
change events to all of the virtual interfaces sharing the same phy for
which the event is received.

5bf9a6c859 P2P: Add event messages for possible PSK failures on P2P groups
It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.

Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).

In addition to indicating the error cases for persistent groups, all
this type of PSK failures end up in the client removing the group with
the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

eb32460029 Fix switching from EAP-SIM to EAP-AKA/AKA'

sudo wpa_cli set_network 0 ssid '"eap-sim"'
sudo wpa_cli set_network 0 key_mgmt WPA-EAP
sudo wpa_cli set_network 0 eap SIM

sudo wpa_cli set_network 0 pin '"1234"'
sudo wpa_cli set_network 0 pcsc '""'
sudo wpa_cli select_network 0
------------------

Then EAP-AKA connection resulted in fail.
wpa_supplicant log is below.

------------------
wlan0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 23 (AKA) selected
SCARD: Non-USIM card - cannot do UMTS auth
EAP-AKA: UMTS authentication failed (AUTN)
wlan0: CTRL-EVENT-EAP-FAILURE EAP authentication failed
------------------

This occurs because on the first EAP-SIM authentication, the SIM/USIM
card in the device was recognized as SIM card even if it is USIM card.

So this patch changes it to recognize as USIM card even if EAP-SIM
authentication was required.

I have tested these switching cases.

43ee470494 P2P: Immediate group removal in GC in case of deauthentication
Right now in case of deauthentication from GO, immediate group removal will
happen in GC only if the deauthentication packet has a valid IE. However,
the IE in deauthentication packet is mandated only for managed P2P group.
So in normal P2P group the group removal is delayed and will happen later
only in group idle timeout.

This fixes a regression from commit

for data->deauth_info != NULL to data->deauth_info->ie != NULL.

86bd141050 Change WEP network selection to reject WPA/WPA2 APs
Previously, wpa_supplicant behavior in WEP configuration was to try to
mimic a device that is not aware of WPA/WPA2 and as such, it tried to
connect to a WPA/WPA2 AP with the assumption that the AP could be
providing support for both WEP and WPA/WPA2 stations in the same BSS.
Such APs could have been used during transition from WEP to more secure
options, but that type of deployment have not been used in large number
and are not really of much use anymore taken into account that more or
less all new devices support WPA/WPA2. That combined with the preference
to deprecate WEP justifies removing this use case and making WEP
networking matching more strict by using the knowledge of AP advertising
WPA/WPA2 as an indication of WEP not being supported.

13adc57b39 IBSS RSN: Add peer restart detection
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.
