9b635d0bde Remove link_test and test_wpa
These wpa_supplicant test programs have not been maintained for years
and it would take significant effort to get these into working state.
Since there does not seem to be any real need for these based on lack of
maintenance, it is easier to just drop these tools for now.

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.

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.

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.

73ed03f333 wpa_supplicant: Add GTK RSC relaxation workaround
Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.

Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

ea6030c77f Restore previous wpa_state in scan-only result handler
The SCAN TYPE=ONLY results do not trigger a connection operation
automatically. As such, there was no explicit operation that would
change wpa_state after such a scan-only operation and WPA_SCANNING state
could have been left in effect until the next operation is triggered by
an external command. This is not desirable, so restore the wpa_state
that was in use when the scan was started in case WPA_SCANNING state is
still set when the scan operation completes.

67deaa582d l2_packet: Add build option to disable Linux packet socket workaround
Linux packet socket workaround(*) has an impact in performance when the
workaround socket needs to be kept open to receive EAPOL frames. While
this is normally avoided with a kernel that has the issue addressed by
closing the workaround packet socket when detecting a frame through the
main socket, it is possible for that mechanism to not be sufficient,
e.g., when an open network connection (no EAPOL frames) is used.

Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the
workaround. This build option is disabled by default and can be enabled
explicitly on distributions which have an older kernel or a fix for the
kernel regression.

Also remove the unused variable num_rx.

(*) Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596
('bridge: respect RFC2863 operational state') from 2012 introduced a
regression for using wpa_supplicant with EAPOL frames and a station
