eab2b50dc8 P2P: Cancel group formation timeout on client connection
It was possiblle for the group formation timeout to be left running even
after the P2P Client connected to the group if the WPS provisioning step
was not completed cleanly (e.g., due to WSC_Done not getting received
from the client). There is no need to remove the group in such case due
to the initial group formation timeout, so work around this by removing
that timeout on data connection.

b2b688d18d P2P: Fix crash when failed to create GO interface
wpa_supplicant crashes if driver configuration for AP mode interface
configuration fails after group negotiation. This is because of a
regression from commit 1075b29571 that
ends up freeing the wpa_s instance from within
wpa_supplicant_create_ap() without the caller knowing.

Fix this by using an eloop timeout to free remove the P2P group so that
wpa_supplicant_create_ap() and especially wpa_supplicant_associate()
callers do not need to know about interface getting possibly removed. In
addition, move the P2P specific code into p2p_supplicant.c where it
really belongs. This allows the already existing group formation timeout
to be used by reducing the timeout to zero.

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.

05766ed8de P2P: Allow per-device PSK to be assigned
"wpa_cli p2p_set per_sta_psk <0/1>" can now be used to disable/enable
use of per-device PSKs in P2P groups. This is disabled by default.
When enabled, a default passphrase is still generated by the GO for
legacy stations, but all P2P and non-P2P devices using WPS will get
a unique PSK.

This gives more protection for the P2P group by preventing clients from
being able to derive the unicast keys used by other clients. This is
also a step towards allowing specific clients to be removed from a group
reliably without having to tear down the full group to do so.

eb32460029 Fix switching from EAP-SIM to EAP-AKA/AKA'
Switching EAP method from EAP-SIM to EAP-AKA fails.
wpa_cli commands are below.

------------------
sudo wpa_cli add_network
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 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.

c1c0b35fea P2P: Postpone concurrent scans when waiting for first client as GO
Previously, concurrent station mode scans were postponed during an
ongoing P2P group formation up to the point of completed WPS
provisioning step. This would allow a scan to be started before the P2P
client has completed association for the data connection if a scan
request were timed to hit the window between the provisioning step and
the following association. Avoid this by extending P2P-in-progress state
to continue until the first data connection has been completed as part
of group formation. Use a ten second timeout for this to avoid leaving
scans disabled indefinitely if the client fails to connect completely.

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.

080585c01a Add support for OCSP stapling to validate server certificate

configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.

hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

There is no point in marking a BSS temporarily blacklisted based on a

unexpected BSS getting selected on the next connection attempt. In
addition, the code to try to find another BSS within the ESS could

407be00b6c P2P: Postpone P2P scan only if station mode scan is pending
sta_scan_pending was supposed to be accurate enough for determining
whether a P2P scan needs to be postponed. However, it has turned out
that there were cases where sta_scan_pending was not cleared properly.
While the known cases have now been addressed, it is possible that some
other cases may still exist. To avoid issues with P2P operationg getting
stuck, verify more carefully that there is a real pending station mode
scan (either in progress or scheduled to be requested).

There were couple of code paths that could end up stopping station mode

p2p_ignore_shared_freq=1 in the configuration file (or "SET
p2p_ignore_shared_freq 1" on control interface) can now be used to
configure wpa_supplicant to ignore the preference on shared operating
channel when the driver support multi-channel concurrency. The default
behavior is to try to start any new P2P group on an operating channel
that is already in use on another virtual interface to avoid extra cost
from hopping between multiple channels. If this new parameter is set to
1, such preference is not used and instead, the channel for the new P2P
group is selected based on other preferences while ignoring operating
channels of any concurrent connection.

77e4e85321 P2P: Mark peer authorized for persistent group invitation
When p2p_invite persistent=<id> is used to request a persistent group to
be re-invoked, the peer may reply with status=1 (info not yet available)
if upper layer processing of the invitiation is requested. The peer is
ten expected to start another invitation exchanged within 120 seconds if
the user authorizes the connection. Allow this process to be used more
easily by automatically authorizing the peer that we tried to invite to
use this second invitation sequence even if persistent_reconnect=0.

For this mechanism to work, the device that starts the invitation needs
to start listen mode to be able to receive the invitation request from
the peer. At least for now, this is not done automatically, but future
changes could potentially enable this automatically at least if there
are no concurrent operations in progress.

Example sequence on the initiator:

cmd: P2P_INVITE persistent=1 peer=<addr>
event: P2P-INVITATION-RESULT status=1
cmd: P2P_LISTEN 120
wait for peer to start another invitiation round.. group will be
re-invoked automatically

On the peer (with persistent_reconnect=0):

event: P2P-INVITATION-RECEIVED sa=<addr> persistent=1 [freq=<MHz>]
wait for user approval
cmd: P2P_INVITE persistent=1 peer=<addr>
group will be re-invoked automatically

does not happen and the GO is started without successful (status=0)
invitation exchange, the operating channel for the group may end up
getting set in a way that the P2P client is not able to support. Provide
optional freq parameter in the P2P-INVITATION-RECEIVED event on the GO
side. If this parameter is received and the upper layer decides to issue
P2P_GROUP_ADD command, that command should include this freq parameter
to make sure the operating channel gets selected from the set that the
peer can support.

ff4178d57c TDLS: Pass peer's HT Capability and QOS information during sta_add
The information of the peer's HT capability and the QOS information is
required for the driver to perform TDLS operations. Pass this
information to the driver when the peer station is getting added.

b8df43dec6 TDLS: Fix add/set STA operation
Commit a9a1d0f08a added vht_capabilities
to struct hostapd_sta_add_params but forgot to update
wpa_supplicant_tdls_peer_addset() to initialize the variable to NULL.
This could result in uninitialized pointer being used in
driver_nl80211.c when adding a TDLS peer entry. Fix this by clearing the
hostapd_sta_add_params with memset.

7b44ff2c21 TDLS: Tear down peers when disconnecting from the AP
A TDLS Teardown frame with Reason Code 3 (Deauthenticated because
sending STA is leaving (or has left) IBSS or ESS) shall be transmitted
to all TDLS peer STAs (via the AP or via the direct path) prior to
transmitting a Disassociation frame or a Deauthentication frame to the
AP.

c5f10e804a Use more accurate timestamps for scan results
For various P2P use cases, it is useful to have more accurate timestamp
for the peer information update. This commit improves scan result
handling by using a single timestamp that is taken immediately after
fetching the results from the driver and then using that value to
calculate the time when the driver last updated the BSS entry. In
addition, more debug information is added for P2P peer updates to be
able to clearly see how old information is being used here.

ec01d5f6b0 P2P: Avoid concurrent scans during all steps of group formation
Previously, only some P2P states were considered to postpone concurrent
station mode scans during group formation. Especially the WPS
provisioning step was skipped due to issues to scans run on the P2P
client interface (see commit fc6997b345).
This is not ideal since a concurrent scan can slow down group formation
considerably and potentially make it time out. Enforce p2p-in-progress
through all steps of group formation on another interface to address
this.

77dfafd07d P2P: Cancel group formation timeout on group removal (on client)
Group formation timeout is normally canceled when 4-way handshake is
completed (WPA_COMPLETED -> wpas_p2p_completed). However, it is possible
for the GO to stop the group before this happens (i.e., send
Deauthentication frame with reason code 3 before 4-way handshake is
completed). This resulted in the group getting removed, but the group
formation timeout left behind. The unexpected timeout may then result in
undesired termination of the following operation. Fix this by canceling
the group formation timeout in wpas_p2p_group_delete() similarly to how
group idle timeout was canceled there.

"WPS" to the dbus interface. It did not add the new
WPAS_DBUS_BSS_PROP_WPS property to the function responsible for marking
changed properties though. This cause the following messages to be
