0f039e3432 Add an option to create interface of a certain type with INTERFACE_ADD
Some drivers do not support having two station interfaces, so the fact
that wpa_supplicant always creates a new interface in station mode, even
if it will be used as another type of interface, may prevent
wpa_supplicant from creating new interfaces. Allow setting the interface
type when a new interface is created so that interfaces of supported
types can be created.

Currently supported types are station ("sta") and AP ("ap"). If the
interface type is not specified, a station interface will be created.

d8a3b66d7f driver: Make setting up AP optional when creating AP interface
When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.

In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.

Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.

2c51c0bd83 P2P: Clear send action work without waiting on find/stop/listen
When clearing pending TX action to start a new P2P operation like
P2P_FIND or P2P_LISTEN, wpas_p2p_action_tx_clear() was used to clear
the send action work. However, in cases where the action work has wait
time, it is not cleared immediately but only after the wait time ends.
This may cause delay in starting the P2P operation.

Fix that by always clearing the send action work immediately on these
P2P commands that result in immediate P2P state change and practically
stopping a previous operation, if one was pending.

6bdc43c4db AP: Avoid 20/40 MHz co-ex scan if PRI/SEC switch is not allowed
When an AP is started on the 5.2 GHz band with 40 MHz bandwidth, a
scan is issued in order to handle 20/40 MHz coexistence. However,
the scan is issued even if iface->conf->no_pri_sec_switch is set,
which is redundant.

Fix this by checking iface->conf->no_pri_sec_switch before starting
the scan.

757785dab2 nl80211: Clear ignore_next_local_deauth flag
The de-authentication flow in wpa_driver_nl80211_deauthenticate() can
result in a locally generated de-authentication event. To avoid getting
this extra event ignore_next_local_deauth flag is set, and should be
cleared when the next local deauth event is received. However, it is not
cleared when the event shows up after the wpa_supplicant has started a
connection with a new AP, and as a result it might ignore future
deauth event from the driver.

Fix this by clearing the flag if the event is locally generated.

cb2a926df8 nl80211: Clear ignore_next_local_deauth and ignore_deauth_event
The authentication flow in wpa_driver_nl80211_authenticate() can
result  in a locally generated de-authentication, in which both
next_local_deauth and ignore_next_local_deauth are set.

However, in mlme_event_deauth_disassoc(), when ignore_deauth_event is
set, the flag is cleared, but the flow immediately returns leaving
ignore_next_local_deauth set, which can result in ignoring future deauth
event from the driver, leaving the wpa_supplicant in an inconsistent
state.

Fix this by clearing both flags in case that next_local_deauth is set.

f32227ed9e Add QCA vendor attribute and event to indicate subnet change status
This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.

The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)

d38c7be0f0 Skip SELECT_NETWORK steps only if already connected or connecting
Commit 2a6f78fbbe ('Do not re-associate on
SELECT_NETWORK to current network') started skipping all SELECT_NETWORK
connection steps if the selected network had already been selected
previously. This happened regardless of whether the connection was
already established. This is not necessarily desirable for all cases
where there is no immediate action to even try to connect (e.g., long
wait for the next scan).

Speed this up by allowing the SELECT_NETWORK operation to get started if
there is no connection or ongoing connection attempt with the selected
network.

25eb7fcbb4 Fix EAPOL reauth after FT protocol or offloaded PMKSA cache use
The EAP peer state machine moved from IDLE to FAILURE state when the
EAPOL Authenticator triggered reauthentication with an
EAP-Request/Identity in a case where the associated started with FT
protocol or offloaded PMKSA cache use (4-way handshake using a
previously acquired PMK). This happened due to the altSuccess=TRUE
setting being left behind and not cleared when processing the restart of
authentication. Fix this by clearing altAccept and eapSuccess when going
through SUPP_PAE RESTART state.

5e238cc682 WPS: Reconnect for a failed data connection when STA_AUTOCONNECT is 0
If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates a failure for the data
connection after successful WPS handshake, it is possible to hit a case
where wpa_s->disconnected is set to 1 and further attempts to connect
shall stop.

While "STA_AUTOCONNECT 0" is used to disable automatic reconnection
attempts in general, this specific WPS case can benefit from trying
again even with that configuration for a short period of time. Extend
the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to
apply for ignoring disabled STA_AUTOCONNECT immediately after a WPS
provisioning step.
