As the current regulatory database is only about 4k big, and already
difficult to extend, we decided that overall it would be better to
get rid of the complications with CRDA and load the database into the
kernel directly, but in a new format that is extensible.
The new file format can be extended since it carries a length field
on all the structs that need to be extensible.
In order to be able to request firmware when the module initializes,
move cfg80211 from subsys_initcall() to the later fs_initcall(); the
firmware loader is at the same level but linked earlier, so it can
be called from there. Otherwise, when both the firmware loader and
cfg80211 are built-in, the request will crash the kernel. We also
need to be before device_initcall() so that cfg80211 is available
for devices when they initialize.

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

There's no need to allocate a portid structure and then, for
each of those, walk the interfaces - we can just add a flag
to each interface and walk those directly. Due to padding in
the struct, we can even do it without any memory cost, and
it even simplifies the code.

Sharing DFS channel state across multiple wiphys (radios) could
be useful with multiple radios on the system. When one radio
completes CAC and markes the channel available another radio
can use this information and start beaconing without really doing
CAC.
Whenever there is a state change in dfs channel associated to
a particular wiphy the the same state change is propagated to
other wiphys having the same DFS reg domain configuration.
Also when a new wiphy is created the dfs channel state of
other existing wiphys of same DFS domain is copied.

Change the SET CQM command's RSSI threshold attribute to accept any
number of thresholds as a sorted array. The API should be backwards
compatible so that if one s32 threshold value is passed, the old
mechanism is enabled. The netlink event generated is the same in both
cases.
cfg80211 handles an arbitrary number of RSSI thresholds but drivers have
to provide a method (set_cqm_rssi_range_config) that configures a range
set by a high and a low value. Drivers have to call back when the RSSI
goes out of that range and there's no additional event for each time the
range is reconfigured as there was with the current one-threshold API.
This method doesn't have a hysteresis parameter because there's no
benefit to the cfg80211 code from having the hysteresis be handled by
hardware/driver in terms of the number of wakeups. At the same time
it would likely be less consistent between drivers if offloaded or
done in the drivers.

The nl80211_nan_dual_band_conf enumeration doesn't make much sense.
The default value is assigned to a bit, which makes it weird if the
default bit and other bits are set at the same time.
To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy
configuration to let the drivers define which bands are supported.
This is exposed to the userspace, which then can make a decision on
which band(s) to use. Additionally, rename all "dual_band" elements
to "bands", to make things clearer.

Disconnect or deauthenticate when the owning socket is closed if this
flag is supplied to CMD_CONNECT or CMD_ASSOCIATE. This may be used
to ensure userspace daemon doesn't leave an unmanaged connection behind.
In some situations it would be possible to account for that, to some
degree, in the deamon restart code or in the up/down scripts without
the use of this attribute. But there will be systems where the daemon
can go away for varying periods without a warning due to local resource

This can't really be supported right now, because the IBSS
interface may change its beacon interval at any time due to
joining another network; thus, there's already "support"
for different beacon intervals here, implicitly.
Until we figure out how we should handle this case (continue
to allow it to arbitrarily join? Join only if compatible?)
disallow advertising that different beacon intervals are
supported if IBSS is allowed.

The old WDS 4-addr frame support is very limited, e.g.
* no encryption is possible on such links
* it cannot support rate/HT/VHT negotiation
* management APIs are very restricted
These make the WDS legacy mode useless in practice.
All of these are resolved by the 4-addr AP/client support,
so there's also no reason to improve WDS in the future.
Therefore, add a Kconfig option to disable legacy WDS.
This gives people an "emergency valve" while they migrate
to the better-supported 4-addr AP/client option; we plan
to remove it (and the associated cfg80211/mac80211 code,
which is the ultimate goal) in the future.

This change alters the semantics of NL80211_CMD_DEL_INTERFACE events
by always sending this event whenever a net_device object associated
with a wdev is destroyed. Prior to this change, this event was only
emitted as a result of NL80211_CMD_DEL_INTERFACE command sent from
userspace. This allows userspace to reliably detect when wireless
interfaces have been removed, e.g. due to USB removal events, etc.
For wireless device objects without an associated net_device (e.g.
NL80211_IFTYPE_P2P_DEVICE), the NL80211_CMD_DEL_INTERFACE event is
now generated inside cfg80211_unregister_wdev.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.
In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.
Supporting beacon report is required for Multi Band Operation (MBO).

Since cfg80211 frequently takes actions from its netdev notifier
call, wireless extensions messages could still be ordered badly
since the wext netdev notifier, since wext is built into the
kernel, runs before the cfg80211 netdev notifier. For example,
the following can happen:
5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default
link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff
5: wlan1: <BROADCAST,MULTICAST,UP>
link/ether
when setting the interface down causes the wext message.
To also fix this, export the wireless_nlevent_flush() function
and also call it from the cfg80211 notifier.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

This callback is currently not allowed to sleep, which makes it more

Add a new regulatory flag that allows a driver to manage regdomain
changes/updates for its own wiphy.
A self-managed wiphys only employs regulatory information obtained from
the FW and driver and does not use other cfg80211 sources like
beacon-hints, country-code IEs and hints from other devices on the same
system. Conversely, a self-managed wiphy does not share its regulatory
hints with other devices in the system. If a system contains several
devices, one or more of which are self-managed, there might be
contradictory regulatory settings between them. Usage of flag is
generally discouraged. Only use it if the FW/driver is incompatible
with non-locally originated hints.
A new API lets the driver send a complete regdomain, to be applied on
its wiphy only.
After a wiphy-specific regdomain change takes place, usermode will get
a new type of change notification. The regulatory core also takes care

Currently it can send regulatory domain change notification before any
NEW_WIPHY notification. Moreover, if rfill_register() fails, calling
wiphy_unregister() will send a DEL_WIPHY though no NEW_WIPHY had been
sent previously.
Thus reordering so it properly notifies NEW_WIPHY before any other.
