Request the driver to send a Deauthentication frame before doing
any other disconnection steps on the session timeout path. This is
needed when PMF is negotiated for the association since the driver
will need to find the STA entry and the PTK for it to be able to
protect the robust Deauthentication frame.

Commit 354c903f8e added setting of
driver_ap_teardown on the hostapd exit path without taking into account
that this may also be called on an error path where the interface has
not been initialized. Fix the resulting NULL pointer dereference to
allow hostapd to exit cleanly in error case.

Add an option to specify a configuration file that can be used to hold
the P2P_DEVICE configuration parameters. If this option is not used, the
P2P_DEVICE configuration parameters will be read from interface
configuration file.
Note that it is advised to use this option in some cases such as:
If a P2P_DEVICE is supported by the driver, the wpa_supplicant creates a
dedicated P2P Device interface, where the configuration file used for
the main interface is used. As a consequence, if the configuration file
includes network definition etc., the wpa_supplicant will try to perform
station specific flows on the P2P Device interface which will fail.
If a P2P_DEVICE is supported by the driver and update_config is used,
the P2P Device configuration data will override the main interface
configuration data.

In case of Automatic Channel Selection (ACS) failure, we do not have a
real fallback path. Interface still remains in ACS state. To reflect we
did not succeed with ACS, simply disable the interface and indicate this
to user/upper layer entity so that a suitable recovery or error
notification can be performed.

wpa_supplicant already allowed beacon interval to be configured for AP
mode operations, but this was not passed to the driver for IBSS even
though the same parameter can used for that case. Add this for the
nl80211 driver interface to allow beacon interval to be controlled for
IBSS as well.

handle_assoc_cb() got this addition, but the check in
hostapd_new_assoc_sta() was not modified to be aware of the OSEN special
case for EAPOL state machines to be used for marking a STA authorized.

This was done in handle_assoc_cb() in ieee802_11.c for drivers that use
hostapd SME/MLME. However, drivers that include SME/MLME implementation
do not use that function and the STA flag needs to be set when
processing the association notification. This is needed to get the STA
entry into showing the proper authorized state and to get the
AP-STA-CONNECTED/DISCONNECTED events on the control interface.

As per IEEE Std 802.11ac-2013, 'Maximum A-MPDU Length Exponent' field
value is in the range of 0 to 7. Previous implementation assumed EXP0 to
be the maximum length (bits 23, 24 and 25 set) what is incorrect.
This patch adds options to set it up within the 0 to 7 range.

For example, the previous implementation considered [44, 48, 52, 56] to
be a valid VHT80 channel -- which it is not. This resulted in, e.g.,
failure to start CAC when channels on overlapped segments included DFS
channels.
Add a check similar to the HT40 one to prevent that. The check is
performed this way as the ACS implementation assumes the primary channel
to be the first channel in a given segment.

Previously, we printed this message as a debug one, which was confusing
in case verbose debug messages were disabled. User could think CAC
started but never ended. Add more parameterss to DFS_EVENT_CAC_START, so
external programs can more easily check what was wrong in case of
errors.

This commit adds an option to optimize AP teardown by leaving the
deletion of keys (including group keys) and stations to the driver.
This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.
For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).

Previously, both this and combination of OUI_WFA and P2P_OUI_TYPE were

CONFIG_TESTING_OPTIONS=y build of wpa_supplicant now allows arbitrary
cfg80211 commands to be performed through the new VENDOR ctrl_iface
command by using a special vendor_id ffffffff. The command identifier
(NL80211_CMD_*) is encoded as the subcmd and the attributes in the
hexformatted data area. Response attributes are returned as a hexdump.
For example, this shows a NL80211_CMD_FRAME and a response (cookie
attribute) on a little endian host:
wpa_cli -i wlan0 vendor ffffffff 59 080003004d0000000800260085090000....

When an interface is disabled through rtm event, wpa_supplicant's
EVENT_INTERFACE_DISABLED is generated, which in turn, may
completely destroy wpa_driver_nl80211_data struct (drv). This
scenario happens now when P2P GO interface is disabled. Since this
struct may be used later in this function it causes segmentation fault.
Fix it by trying to find drv again in the interface list after
wpa_supplicant's event handling.

Add a callback to the driver interface that allows vendor specific
commands to be sent. In addition, a control interface command is added
to expose this new interface outside wpa_supplicant:
Vendor command's format:
VENDOR <vendor id> <sub command id> [<hex formatted data>]
The 3rd argument will be converted to binary data and then passed as
argument to the sub command.
This interface is driver independent, but for now, this is only
implemented for the nl80211 driver interface using the cfg80211 vendor
commands.

interfaces is the call to nl80211_remove_iface(), which can be pulled in

Passing a pointer to an error reply message is not very robust since
memory allocation could fail even for that error message. Instead, use a
separate error value as the return value from get_peer_hwaddr_helper()
and return a pointer to the error message through a pointer-to-pointer
so that the error case will always be clear.
