742e715b31 Simplify ctrl_iface sendto() use
Prepare reply buffer first for all cases and then use a single sendto()
call instead of three calls depending on reply type. This allows simpler
error handling for control interface send operations.

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 select_network 0

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.
