The MBO and OCE specification require the station to mandate use of PMF
when connecting to an MBO/OCE AP that uses WPA2. The earlier
implementation prevented such misbehaving APs from being selected for
connection completely. This looks like the safest approach to take, but
unfortunately, there are deployed APs that are not compliant with the
MBO/OCE requirements and this strict interpretation of the station
requirements results in interoperability issues by preventing the
association completely.
Relax the approach by allowing noncompliant MBO/OCE APs to be selected
for RSN connection without PMF to avoid the main impact of this
interoperability issue. However, disable MBO/OCE functionality when PMF
cannot be negotiated to try to be as compliant as practical with the
MBO/OCE tech spec requirements (i.e., stop being an MBO/OCE STA for the
duration of such workaround association). Also disable support for BTM
in this workaround state since MBO would expect all BTM frames to be
protected.

An earlier change in drivers_ops API for struct external_auth broke the

The implementation depended on the memory array being available in the

when only SSID and BSSID was needed. Fix this by replacing that

Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

Drop the unneeded 'attempt' argument. This was originally used for
indicating an aborted PMKID caching attempt, but a fix in 2006 removed
the only such user and since that time, only attempt == 1 has been used.

Connection with a PMF enabled AP will fail if we try to negotiate PMF
while the local driver does not support this. Since pmf=1 does not
require PMF for a successful connection, it can be ignored in such a
case to avoid connectivity issues with invalid configuration. This makes
it somewhat easier to allow upper layer programs to use pmf=1 default
regardless of driver capabilities.

the previous item was for.

There is no need to keep temporary keys in memory beyond the end of the
association, so explicitly clear any SAE buffers that can contain keys
as soon as such keys are not needed.

Include only the potentially affected channel range in OBSS scans to
reduce the amount of offchannel time needed for scanning when requested
by the AP.
