25a8f9e316 Clear EAPOL supplicant configuration info on current_ssid changes
There were some code paths that allowed obsolete configuration data
pointer to be maintained within EAPOL supplicant in case a network was
removed while not connection to it (i.e., wpa_s->current_ssid not
pointing to the network that was removed). This could result in use of
freed memory, e.g., from eap_sm_notify_ctrl_attached() when a new
control interface connected prior to the EAPOL supplicant configuration
pointer got updated.

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.

cbf41ca796 P2P: Do not delay retries on failure during group formation
4-way handshake may fail under extremely noisy environment and if this
happens during P2P group formation, the 10 second extra delay added in
wpas_auth_failed() can result in running over the 15 second timeout.

Avoid this by skipping the delay mechanism in wpas_auth_failed() for the
P2P group formation case. The P2P formation timeout will take care of
stopping the attempts if the failure condition does not get resolved.

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.

0b9d3b22c8 Interworking: Relax 3GPP info PLMN matching for MNC
3GPP TS 24.232 Annex A.3 allows network operator to advertise only two
digits of MNC even if MNC has three digits. Allow such matches in

cannot be determined reliably. Remove the '-' separator from simulated

avoid unexpected matches should a new element ever be added by 3GPP.

Finally, add more debug prints from PLMN matching to make the logs

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).

576bce9c86 P2P: Direct global ctrl_iface commands automatically for P2P
The P2P management operations like P2P_FIND and P2P_CONNECT are not
really specific to any network interface. These are P2P Device level
operations that are in more global device context. Allow those to be
sent through the global control interface without IFNAME parameter.

For now, these commands are directed within wpa_supplicant to the
network interface that initialized the global P2P context. This may
change in the future if a special context is added for P2P operations.
Anyway, such changes can now be done internally within wpa_supplicant
without affecting this global control interface design from external

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

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.

fbfb0e65bf SAE: Add support for FFC groups
This allows FFC groups to be used with SAE. Though, these groups are not
included in the default sae_groups value based on what is available
since the FFC groups have the additional requirement of using a safe
prime with the current implementation (or specification of the group
order).

9c75e9fb81 WPS: Verify wpa_config_set() return value more consistently
Even though this command is very unlikely to fail, in theory, it could
and the WPS connection would fail in such a case. Return more clearer
failure indication in such a case without even trying to start
reassociation.
