In associations using PMF (IEEE 802.11w/MFP), the infrastructure
implements SA teardown protection by rejecting an (Re)Association
Request frame from an already-associated client. The AP responds with
error 30 (Association request rejected temporarily) to instruct the
(potentially spoofing) client to back off, while it issues an SA Query
procedure to the already-associated client. If the client can respond to
it within the back-off period, it considers the new association to be a
spoof attempt.
However, there are cases where a legitimate client might need to
handle this error response - consider if the STA has deauthenticated,
but the AP cannot hear it (out of range). If the MFP STA has deleted
its keys, it cannot respond to the SA Query procedure.
This association comeback process has commonly been implemented in the
driver, e.g., within mac80211 in case of the Linux drivers that use SME
in userspace. However, there are drivers that do not implement this
functionality. Extended wpa_supplicant to cover such cases as well.
The current implementation interprets this association error as a true
error, and will either add the BSS to the list of ignored BSSIDs, or
continue to try other BSSes. This can cause wpa_supplicant to back off
trying to reconnect for progressively longer intervals, depending on the
infrastructure's configured comeback timeout.
Allow wpa_supplicant to interpret the error, searching for the Timeout
Interval element in the (Re)Association Response frame and starting a
timer in the SME layer to re-associate after the timeout. This can be a
long delay (1-4 seconds in my experience), but it is likely much shorter
than bouncing between nearby BSSes.
This does not change behavior for drivers that implement association
comeback timer internally since they do not report the temporary
association rejection status code to user space.

Decrease the roam difficulty when roaming across the short background
scan threshold (i.e., when the current BSS RSSI is below the threshold
and the selected BSS RSSI is above the threshold). This tends to happen
in normal roaming scenarios when moving from the domain of one AP to
the domain of another.

Since wpa_supplicant version 2.10 the extended capabilities MSCS and SCS
are advertised in the (Re)Association Request frames.
This causes the association request to be rejected by several access
points. Issue was observed with:
- D-Link DIR600
- TP-Link AC1900
- Synology MR2200ac
To avoid this issue the extended capabilities MSCS and SCS shall only be
added if the bss also supports them. While this may not follow the exact
behavior described in IEEE 802.11, this is a reasonable compromise to
avoid interoperability issues since these capabilities cannot be used
with an AP that does not support them anyway.
Note: The Extended Capabilities element is only included in the
Association Request frames if the AP also sent its extended capabilities
(see wpas_populate_assoc_ies()) as a workaround for misbehaving APs.
This workaround exists since version 2.1.

Drivers will often report regdom changes in the middle of a scan if they
detect during that scan that the regulatory domain has changed. If this
happens and we enter a regdom that supports 6 GHz channels when the
previous one didn't (this often happens in 6 GHz-capable regdoms for

we were not able to connect to an AP on a legacy band.

It was possible to hit a case where the SAE PT had not yet been derived,
e.g., when using P2P group re-invocation. Update PT use at the time
authentication is started, if needed, to avoid this. While this is not
really ideal from the externally observable timing view point, this is
done only for the case where there is no other option available with a
dynamically changing network configuration for P2P. Similar design was
already in place for the SAE offload-from-driver (external auth) case.

If the CreateInterface command was used to create a virtual AP
interface, deleting this interface using the RemoveInterface command was
also bringing down the primary interface.
wpa_supplicant never uses hostapd style multi-BSS setup with
type=WPA_IF_AP_BSS and setup_ap=1 to if_add() when creating an AP
interface in wpa_driver_nl80211_if_add(), so it should not go through
the multi-BSS tear down procedure in wpa_driver_nl80211_if_remove(). The
virtual AP resources init and deinit are well handled in
wpa_driver_nl80211_init() and wpa_driver_nl80211_deinit().
Collapse the interface type to WPA_IF_STATION for the D-Bus interface to
skip the multi-BSS cleanup procedure. This is inline with the control
interface design. Add comments before the code to avoid confusion.

Add new 'mac_addr' policy (3) with which supplicant expects to also
obtain 'mac_value' with pregenerated value of MAC address to be used for
given SSID.
The main difference between this policy and policy 1 is the ability to
control persistence of the MAC address used. For example if there is
a requirement to always use the same (but random) MAC address for given
SSID (even if user removes/forgets the network) this could be handled
outside of the wpa_supplicant by using some SSID based hashing scheme to
generate MAC (or by just storing the randomly generated one) and
providing it to wpa_supplicant together with mac_addr=3 policy.

If a higher priority BSS has invalid security parameters, e.g., an
invalid SAE password, and a lower priority BSS is discovered only after
the local network profile has been temporarily disabled, the BSSID
ignoring mechanism is not sufficient to allow the lower priority BSS to
be tried and all consecutive attempts will continue to use the higher
priority BSS. This might prevent connection in some unexpected cases
with invalid network configuration.
Extend BSSID ignoring mechanism to work in this type of a case by
ignoring the BSSID that resulted in disabling the SSID temporarily
during the first connection attempt after having re-enabled the SSID.
This allows a lower priority BSS, if any is available in scan results,
to be tried next to see if it might have working security parameters.

With this option SAE is avoided when the hardware is not capable
of PMF due to missing ciphers.
With this option SAE is avoided on capable hardware when the AP

Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher
necessary for PMF. This enables configurations that can fall back
to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.
Useful when `pmf=1` and `sae_check_mfp=1` are enabled and networks
are configured with ieee80211w=3 (default) and key_mgmt="WPA-PSK SAE".
In this configuration if the device is unable to use PMF due to
lacking BIP group ciphers it will avoid SAE and fallback to
WPA-PSK for that connection.
