time.sleep() in run_roams() is required because the target AP sets the
key once the station was associated. There are races, when the station
processes the (Re)Association Response frame AND the test suite starts
FT_DS before the AP processes its local confirmation and thus
wpa_auth_sm_event(ASSOC_FT). Therefore, the ActionFrame will be lost, as
the AP driver is missing the key.
Since this is this speed is highly synthetic, wait a few milliseconds
before roaming back.

IEEE Std 802.11-2016, 12.7.1.7.1 indicates that the lifetime of the
PMK-R0 (and PMK-R1) is bound to the lifetime of PSK or MSK from which
the key was derived. This is currently stored in r0_key_lifetime, but
cache entries are not actually removed.
This commit uses the r0_key_lifetime configuration parameter when
wpa_auth_derive_ptk_ft() is called. This may need to be extended to use
the MSK lifetime, if provided by an external authentication server, with
some future changes. For PSK, there is no such lifetime, but it also
matters less as FT-PSK can be achieved without inter-AP communication.
The expiration timeout is then passed from R0KH to R1KH. The R1KH verifies
that the given timeout for sanity, it may not exceed the locally configured
r1_max_key_lifetime.

There is no existing mechanism for setting up AP mode functionality with
FT enabled, so there is not really much point in having a build option
for trying to include the AP-to-AP FT functionality into wpa_supplicant
either. Since this build option results in failures to complete the
build, simply remove it completely. This can be restored if there is
ever desire to enable FT functionality in wpa_supplicant controlled AP
mode.

When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.
This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

Previously we set this flag to one in wpa_supplicant_init_iface() if
Wi-Fi controller does not have a dedicated P2P-interface.
This setting had effect only in scope of wpa_supplicant_init_iface() and
it contradicts with comment to struct wpa_interface::p2p_mgmt field.
This comment says that this flag is used only if Wi-Fi controller has
dedicated P2P-device interface.
Also it contradicts with usage of similiar p2p_mgmt field in struct
wpa_supplicant. Again struct wpa_supplicant::p2p_mgmt is set only for
dedicated P2P-device interface.

This fixes sending of FindStopped, GroupFormationFailure, and
InvitationReceived signals in the case of separate P2P-Device interface.
This extends the coverage of the earlier commit
745d62322b ("dbus: Redirect P2P request to
the managment device if present") to these three functions that were
missing the redirection.
Some wireless controllers might have separate P2P-Device interface, see
as example result of 'iw dev':
phy#0
Unnamed/non-netdev interface
...
type P2P-device
...
Interface wlp2s0
type managed
...
In this case there is separate 'struct wpa_supplicant' created for this
p2p-dev-* device as result of 'wpa_supplicant_add_iface >
wpas_p2p_add_p2pdev_interface > wpa_supplicant_add_iface'.
This instance of wpa_supplicant is not registered in D-Bus
(wpas_dbus_register_*) since for corresponding P2P device interface flag
'struct wpa_interface > p2p_mgmt' is set.
But this instance is saved in p2p_init_wpa_s and is used for handling
P2P related D-Bus commands. Therefore we should look for D-Bus path in
the parent of p2p_init_wpa_s instance.
Without this change test dbus_p2p_discovery starts failing if we set
support_p2p_device in vm-run.sh.

In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a
general failure parameter string "failure". This parameter is used for a
notification on the dbus.
This commit reports the EAP method failure error code in a separate
callback.
The solution in this commit is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
commit only implements the reporting for EAP-SIM and EAP-AKA methods
where the Notification Code (in AT_NOTIFICATION) is used as the method
specific error code value.

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

This extends the original IEEE Std 802.11ai-2016 functionality with the

This allows key_mgmt=FT-FILS-SHA256 to be used with FT protocol since

FT-FILS-SHA384 case is still unsupported (it needs support for variable

The previous implementation ended up defaulting to using PRF-SHA1 for
deriving PTK from PMK when SAE was used. This is not correct since the
SAE AKM is defined to be using SHA-256 -based KDF instead. Fix that.

side implementations will need to be updated at the same time to

Previously, the association that used SAE authentication ended up
recalculating the PMKID for EAPOL-Key msg 1/4 using incorrect
PMK-to-PMKID derivation instead of using the previously derived PMKID
from SAE. The correct PMKID was used only when going through PMKSA
caching exchange with a previously derived PMKSA from SAE.
Fix this by storing the SAE PMKID into the state machine entry for the
initial SAE authentication case when there is no explicit PMKSA entry
attached to the station.

Previously, matching PMKSA cache entry ended up clearing XXKey. However,
that XXKey is needed in the specific case where FT-SAE goes through the

When processing 20/40 BSS Coexistence Management frames that do not
explicitly require 40 MHz to be disabled, check whether the reported
channels in 20/40 BSS Intolerant Channel Report element match the
current primary channel. If so, allow 40 MHz operation to continue. This
makes the during-operation updates for 20/40 Operation Permitted more
consistent with the scans during initial BSS startup.
The received 20/40 BSS Intolerant Channel Report channels are to be used
in the OT set in the during-operation determination and the P == OT_i
exception was ignored in the previous implementation which could result
in the AP first starting with 40 MHz and then dropping to 20 MHz on
first received 20/40 BSS Coexistence Management frame even though there
was no change in the neighboring BSSs.
