This implements very initial support of WPS PIN based connections. The
scanning logic attempts to find an AP in PIN mode and tries to connect
to that AP. We currently do not try multiple APs if available or
implement the WSC 1.0 connection logic.
Trigger a roam attempt when the RSSI level has been low for at least 5
seconds using the netdev RSSI LOW/HIGH events. See if neighbor reports
are supported and if so, request and process the neighbor reports list
to restrict the number of channels to be scanned. The scanning part is
not included in this patch for readability.
Remove the keys and other data from struct eapol_sm, update device.c,
netdev.c and wsc.c to use the handshake_state object instead of
eapol_sm. This also gets rid of eapol_cancel and the ifindex parameter
in some of the eapol functions where sm->handshake->ifindex can be
used instead.
If the device is currently connected, we will initiate a disconnection
(or wait for the disconnection to complete) prior to starting the
WSC-EAP association.
We send the scan results where we obtained a PushButton target over to
device object. If EAP-WSC transaction is successful, then the scan
results are searched to find a network/bss combination found in the
credentials obtained. If found, the network is connected to
automatically.
Previously device.c would remove the whole object at the path of the
Device and the WSC interfaces but now the watches are called without the
whole object appearing and disappearing.
Turn netdev watches into device watches. The intent is to refactor out
netdev specific details into its own class and move device specific
logic into device.c away from wiphy.c
Probe Response messages can contain additional attributes tucked away
into the WFA-Vendor specific attribute. Parse these attributes while
making sure the order is as expected.
