bf428a739c P2P: Fix memory leak with driver-based P2P management
If the P2P management operations are handled within the driver, the
P2P service entries were not freed when terminating wpa_supplicant.
Fix this by calling wpas_p2p_service_flush() even if the P2P module
within wpa_supplicant has not been initialized.

1af1c9ceb6 P2P: Fix PD retries on delay in off channel transmission
Commit 488f4a7108 configures a timer
before p2p_send_action(). This may result in the timer getting fired
earlier to the off channel transmission of the frame and thus another PD
request being retransmitted. This shall lead to the new PD request with
an incremented dialog token being transmitted. For the cases where the
later PD request might not be transmitted as the host driver is busy
transmitting the earlier frame, the received PD response could be
dropped for the dialog token mismatch. Remove the timer configuration to
avoid this behavior.

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.

cc8c7b8840 P2P: Remove unnecessary call in resuming p2p_find
Commit 99fcd40409 added a call to update
search delay after failed authentication attempt. This change was
supposed to be only in p2p_supplicant.c for the successful case. The
extra call does not really do anything, but it's good to remove it to
avoid any confusion in the future.

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.

If the p2p_find command is used without the delay parameter, a 500 ms

radio is in an concurrent operation. "p2p_find delay=0" can be used to

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.
