Use only the UUID-E to remove active PBC session(s) at the completion of
successful PBC protocol run. This fixes potential issues with Enrollees
that use multiple MAC addresses and as such, can get multiple entries in
the PBC session list.

are configured.

There's a bug in the getter for the 'Interfaces' property
of /fi/w1/wpa_supplicant1 (new D-Bus interface) which causes a
'Segmentation Fault' when there are multiple interfaces.
Currently hostapd will force HT Mixed Mode if at least one non-GF STA is
associated. This will force _all_ HT transmissions to be protected.
802.11n-2009 doesn't require HT Mixed Mode to be used in case of non-GF
STAs but instead the HT information element contains a flag if non-GF
STAs are present. All STAs are required to protect GF transmissions in
that case. Hence, setting HT Mixed mode if non-GF STAs are present is
superfluous.

Use a specific return value, WPS-PBC-OVERLAP, to indicate a reason
for rejecting a wps_pbc command in wpa_supplicant AP mode if the
PBC mode cannot be started due to PBC session overlap having been
detected during monitor time.
This allows the user to complete WPS provisioning using PBC by
selected a specific Enrollee even if there are other Enrollees
in active PBC mode at the same time. The other Enrollees will be
rejected should they try to connect at the same time.
If the wpa_supplicant configuration file does not specify an UUID,
we need to copy the generated UUID, not the all zeros buffer
reserved for the configured UUID.
Instead of generating a different UUID for each interface, use the
same UUID that was either configured of generated for the first
interface. This avoids potential issues with PBC session overlap
detection should multiple interfaces end up running a PBC scan
at the same time which may happen at least in some P2P use cases.
Ignore possible mismatches in the source address of the frame and only
use UUID-E to check whether a Probe Request or M1 is from the same
Enrollee when figuring out whether there is PBC session overlap. This
is needed to avoid potential issues with Enrollee devices that may have
multiple interfaces indicating active PBC state.
If there is already a link the requested peer, request start of
renegotiation instead of completely new link. This seems to be needed
to allow some driver to accept the trigger for a new negotiation.
tdls_testing 0x80 can now be used to request wpa_supplicant to send
a TDLS Setup Request frame (i.e., try to initiate TDLS setup)
whenever a TDLS Setup Request frame has been received from a peer.
Blindly clearing all struct wpa_tdls_peer members is a risky
operation since it could easily clear pointers to allocated
memory, etc. information that really should not be removed.
Instead of hoping that new code gets added here to restore
the important variables, reverse the approach and only clear
structure members one by one when needed.
This allows the same code path to be used for both protected and
unprotected configurations to limit need for duplicated code in
both the driver and wpa_supplicant.
