a462036a47 WPS: Allow AP that becomes active be tried immediately
Clear the possible blacklisting of a WPS AP during WPS PIN iteration if
the AP moves to selected registrar TRUE state or if it adds our MAC
address to the list of authorized MACs.

f9f0526bcd WPS: Maintain more AP state during WPS PIN iteration
Maintain state of WPS APs during iteration to find the correct AP for
WPS PIN operation when no specific BSSID is specified. This information
can be used for optimizing the order in which the APs are tried. This
commit is only adding the collection of the information and more
detailed debug information to make debug logs more helpful in figuring
out how the AP selection order could be improved.

d42bc5e178 Handle long configuration file lines more gracefully
Skip the end of long configuration lines that get truncated in
wpa_config_get_line(). Without this, the rest of the file was being
parsed as another line and that resulted in an unexpected error
message (wrong line number and wrong starting point).

In addition, increase the read buffer for network blocks from 256
to 2000 since p2p_client_list parameter can have long values. These
were supposed to truncated cleanly, but the unexpected processing of
the end of the file (which is now fixed in this commit) could cause
configuration file to be rejected.

99fcd40409 P2P: Allow scan operations during p2p_find
Previously, all station mode scan operations were either skipped or
delayed while any P2P operation was in progress. To make concurrent
operations easier to use, reduce this limitation by allowing a scan
operation to be completed in the middle of a p2p_find. In addition,
allow station mode association to be completed. When the station mode
operation is run to its completion (scan results not acted on,
connection to an AP completed, connection failed), resume the p2p_find
operation.

065d2895b4 Add UNAUTH-TLS vendor specific EAP type
This EAP type uses a vendor specific expanded EAP header to encapsulate
EAP-TLS with a configuration where the EAP server does not authenticate
the EAP peer. In other words, this method includes only server
authentication. The peer is configured with only the ca_cert parameter
(similarly to other TLS-based EAP methods). This method can be used for
cases where the network provides free access to anyone, but use of RSN
with a securely derived unique PMK for each station is desired.

The expanded EAP header uses the hostapd/wpa_supplicant vendor
code 39068 and vendor type 1 to identify the UNAUTH-TLS method.
