31bc66e4d1 More forceful clearing of stack memory with keys
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.

b1aee7a622 DPP: Fix bootstrapping URI parser to handle channel list for an opclass
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.

69afb6b395 FILS: Verify RSNE match between Beacon/Probe Response and (Re)AssocResp
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.

831d8c9cf5 FILS: Add RSNE into (Re)Association Response frame
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.
