Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).
Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).
Tested with nl80211 DFS offload implementation.

Explicitly check the PMKSA cache entry to have matching SAE AKMP for the
case where determining whether to use PMKSA caching instead of new SAE
authentication. Previously, only the network context was checked, but a

and SAE, so should check the AKMP as well.

The RSN supplicant state machine PMK was set based on WPA PSK even for
the cases where SAE would be used. If the AP allows PMKSA caching to be
used with SAE, but does not indicate the selected PMKID explicitly in
EAPOL-Key msg 1/4, this could result in trying to use the PSK instead of
SAE PMK. Fix this by not setting the WPA-PSK as default PMK for SAE
network profiles and instead, configuring the PMK explicitly from the
found PMKSA cache entry.

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

This extends the coverage of the earlier commit
745d62322b ("dbus: Redirect P2P request to

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.
