TX code is not applicable for any FIPS mode operation, so the simplest

This allows driver-based preference list to override default operating
channel selection mechanism by using a non-social P2P find if needed.
Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
Previously, this was assumed to be the case due to default channel
selection behavior. However, that may not be the case with driver-based
preference list processing. Enforce a social channel to be used as the
operating channel here since dev[2] uses social channel only device
discovery and needs to find the GO.

When processing a GO Negotiation Request and Response, if local driver
supports the preferred channel list extension, then:
- Check if peer's preference for operating channel is already included
in our preferred channel list and if so, take the oper_channel as is.
- If peer's preference for operating channel is not in local device's
preferred channel list and peer device has provided its preferred
frequency list in the GO Negotiation Request/Response, then find a
channel that is common for both preferred channel lists and use it
for oper_channel.
- If peer's preference for operating channel is not in local device's
preferred channel list and peer device doesn't use preferred channel
list extension, i.e., no preferred channel list in GO Negotiation
Request/Response, then look for a channel that is common for local
device's preferred channel list and peer's list of supported channels
and use it for oper_channel.
- In case no common channel is found, use the peer's preference for
oper_channel as is.

Add an extra condition to omit operating channel preference when
building GO Negotiation Response. If the local device supports the
preferred frequency list extension, then when sending a GO Negotiation
Response frame, advertise the preferred operating channel unless local
device is assuming the P2P Client role and has an empty preferred
frequency list, in which case local device can omit its preference for
the operating channel.
This change helps make use of the preferred frequency list and the
calculated best channel for both negotiating parties of the P2P
connection.

Commit 983422088f ('nl80211: Add means to
query preferred channels') return success if no driver wrapper callback
was provided for fetching the preferred channel list. That is
problematic since the *num argument is not updated and uninitialized
freq_list could end up getting used with arbitrary frequency values. Fix
this by returning error in case the values were not available due to
driver wrapper not implementing the function. This matches the style
used in the driver_nl80211.c implementation for the case where the
driver does not support such fetch operation.

The issue with the special form of TLS session tickets has been fixed in

openssl_handshake() was checking only that in_data is not NULL and not
its length when determining whether to call BIO_write(). Extend that to

unnecessary BIO_write() call at the beginning of a TLS handshake on the
client side. This did not cause issues with OpenSSL versions up to
