gcc 8.3.0 was apparently clever enough to optimize away the previously
used os_memset() to explicitly clear a stack buffer that contains keys
when that clearing happened just before returning from the function.
Since memset_s() is not exactly portable (or commonly available yet..),
use a less robust mechanism that is still pretty likely to prevent
current compilers from optimizing the explicit clearing of the memory
away.

The Session-Id derivation for EAP-AKA in RFC 5247 only explained how the
Session-Id is derived for regular authentication. Jouni reported it as
an errata with text explaining how to derive it during fast
reauthentication.
This patch now exports the Session-Id for EAP-AKA during fast

The length check for the BSS Termination Duration subelement was
accidentally removed and this could result in reading up to 10 bytes
beyond the end of a received frame. The actual read bytes would be
stored locally, but they were not used for anything, so other than
reading beyond the end of an allocated heap memory buffer, this did not
result in any behavior difference or exposure of the bytes.

The bootstrapping URI format for DPP was extended during protocol design
to allow a list of channels without having to repeat the same operating
class information for each channel. That change was not included in the
initial implementation of the parser and a channel-list like
"C:81/1,6,11" would not be understood correctly (i.e., only the longer
"C:81/1,81/6,81/11" form would have been parsed correctly).
Fix this by extending the parser to accept both the shorter and longer
form for a list of channels within a single operating class.

IEEE Std 802.11ai-2016 requires the FILS STA to do this check, but this
was missing from the initial implementation. The AP side behavior was
not described properly in 802.11ai due to a missing change in the
(Re)Association Response frame format tables which has resulted in some
deployed devices not including the RSNE.
For now, use an interoperability workaround to ignore the missing RSNE
and only check the payload of the element if it is present in the
protected frame. In other words, enforce this validation step only with
an AP that implements FILS authentication as described in REVmd while
allowing older implementations to skip this check (and the protection
against downgrade attacks). This workaround may be removed in the future
if it is determined that most deployed APs can be upgraded to add RSNE
into the (Re)Association Response frames.

This AP behavior was missing from IEEE Std 802.11ai-2016, but it is
needed for the RSNE validation to work correctly and for a FILS STA to
be able to perform the mandatory check for RSNE matching when processing
the (Re)Association Response frame (as described in 802.11ai). REVmd
will be updating the standard to cover this AP case, so prepare the
implementation to match that. Without this, a FILS STA might reject
association whenever using FILS authentication.
