This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

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
management.

DFS requirement for ETSI domain (section 4.7.1.4 in
ETSI EN 301 893 V1.8.1) is the only one which explicitly
states that once DFS channel is marked as available afer
the CAC, this channel will remain in available state even
moving to a different operating channel. But the same is
not explicitly stated in FCC DFS requirement. Also, Pre-CAC
requriements are not explicitly mentioned in FCC requirement.
Current implementation in keeping DFS channel in available
state is same as described in ETSI domain.
For non-ETSI DFS domain, this patch gives a grace period of 2 seconds
since the completion of successful CAC before moving the channel's
DFS state to 'usable' from 'available' state. The same grace period
is checked against the channel's dfs_state_entered timestamp while
deciding if a DFS channel is available for operation. There is a new
radar event, NL80211_RADAR_PRE_CAC_EXPIRED, reported when DFS channel
is moved from available to usable state after the grace period. Also
make sure the DFS channel state is reset to usable once the beaconing
operation on that channel is brought down (like stop_ap, leave_ibss
and leave_mesh) in non-ETSI domain.

Currently the connect event from driver takes all the connection
response parameters as arguments. With support for new features these
response parameters can grow. Use a structure to pass these parameters
rather than passing them as function arguments.

This adds defines and nl80211 extensions to allow FILS Authentication to
be implemented similarly to SAE. FILS does not need the special rules
for the Authentication transaction number and Status code fields, but it
does need to add non-IE fields. The previously used
NL80211_ATTR_SAE_DATA can be reused for this to avoid having to
duplicate that implementation. Rename that attribute to more generic
NL80211_ATTR_AUTH_DATA (with backwards compatibility define for
NL80211_SAE_DATA).
Also document the special rules related to the Authentication
transaction number and Status code fiels.

commit e6f462df9acd2a3295e5d34eb29e2823220cf129 upstream.
When mac80211 abandons an association attempt, it may free
all the data structures, but inform cfg80211 and userspace
about it only by sending the deauth frame it received, in
which case cfg80211 has no link to the BSS struct that was
used and will not cfg80211_unhold_bss() it.
Fix this by providing a way to inform cfg80211 of this with
the BSS entry passed, so that it can clean up properly, and
use this ability in the appropriate places in mac80211.
This isn't ideal: some code is more or less duplicated and
tracing is missing. However, it's a fairly small change and
it's thus easier to backport - cleanups can come later.

This enhances the connect timeout API to also carry the reason for the
timeout. These reason codes for the connect time out are represented by
enum nl80211_timeout_reason and are passed to user space through a new
attribute NL80211_ATTR_TIMEOUT_REASON (u32).

Add support to use a random local address (Address 2 = TA in transmit
and the same address in receive functionality) for Public Action frames
in order to improve privacy of WLAN clients. Applications fill the
random transmit address in the frame buffer in the NL80211_CMD_FRAME
command. This can be used only with the drivers that indicate support
for random local address by setting the new
NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or
NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features.
The driver needs to configure receive behavior to accept frames to the
specified random address during the time the frame exchange is pending
and such frames need to be acknowledged similarly to frames sent to the
local permanent address when this random address functionality is not
used.

This callback is currently not allowed to sleep, which makes it more
difficult to implement proper driver methods in mac80211 than it has
to be. Instead of doing asynchronous work here in mac80211, make it
possible for the callback to sleep by doing some asynchronous work
in cfg80211. This also enables improvements to other drivers, like
ath6kl, that would like to sleep in this callback.
While at it, also fix the code to call the driver on the implicit
unregistration when an interface is removed, and do that also when
a P2P-Device wdev is destroyed (otherwise we leak the structs.)

802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".
In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)
The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation.
But, memory get allocated under spin_lock_bh(), this implies atomic context.
So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all
occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake),
and it should be this way or warning triggered in the memory allocation code.
Remove @gfp parameter as no actual choice exist, and use hard coded
GFP_ATOMIC for memory allocation.

Move the counting part of the interface combination check from
cfg80211 to mac80211.
This is needed to simplify locking when the driver has to perform a

It was possible to break interface combinations in
the following way:
combo 1: iftype = AP, num_ifaces = 2, num_chans = 2,
combo 2: iftype = AP, num_ifaces = 1, num_chans = 1, radar = HT20
With the above interface combinations it was
possible to:
step 1. start AP on DFS channel by matching combo 2
step 2. start AP on non-DFS channel by matching combo 1
This was possible beacuse (step 2) did not consider
if other interfaces require radar detection.
The patch changes how cfg80211 tracks channels -
instead of channel itself now a complete chandef
is stored.

To report channel width correctly we have
to send correct channel parameters from
mac80211 when calling cfg80211_cac_event().
This is required in case of using channel width
higher than 20MHz and we have to set correct
dfs channel state after CAC (NL80211_DFS_AVAILABLE).

This fixes the potential issue that the BSS struct that we use
and later assign to wdev->current_bss is removed from the scan
list while associating.

Doing so will allow us to hold the BSS (not just ref it) over the
association process, thus ensuring that it doesn't time out and
gets invisible to the user (e.g. in 'iw wlan0 link'.)
This also fixes a leak in mac80211 where it doesn't always release
the BSS struct properly in all cases where calling this function.
This leak was reported by Ben Greear.

The current internal SME implementation in cfg80211 is
very mixed up with the MLME handling, which has been
causing issues for a long time. There are three things
that the implementation has to provide:
* a basic SME implementation for nl80211's connect()
call (for drivers implementing auth/assoc, which is
really just mac80211) and wireless extensions
* MLME events for the userspace SME
* SME events (connected, disconnected etc.) for all
different SME implementation possibilities (driver,
cfg80211 and userspace)
To achieve these goals it isn't necessary to track the
software SME's connection status outside of it's state
(which is the part that caused many issues.) Instead,
track it only in the SME data (wdev->conn) and in the
general case only track whether the wdev is connected
or not (via wdev->current_bss.)
Also separate the internal implementation to not have
callbacks from the SME events, but rather call it from
the API functions that the driver (or rather mac80211)
calls. This separates the code better.

Do some cleanups in the cfg80211 SME APIs, which are
only used by mac80211.
Most of these functions get a frame passed, and there
isn't really any reason to export multiple functions
as cfg80211 can check the frame type instead, do that.
Additionally, the API functions have confusing names
like cfg80211_send_...() which was meant to indicate
that it sends an event to userspace, but gets a bit
confusing when there's both TX and RX and they're not
all clearly labeled.

By making all the API functions require wdev locking we
can clean up the API a bit, getting rid of the locking

Using separate locks in cfg80211 and mac80211 has always
caused issues, for example having to unlock in places in
mac80211 to call cfg80211, which even needed a framework
to make cfg80211 calls after some functions returned etc.
Additionally, I suspect some issues people have reported
with the cfg80211 state getting confused could be due to
such issues, when cfg80211 is asking mac80211 to change
state but mac80211 is in the process of telling cfg80211
that the state changed (in another way.)

Virtually all code paths in cfg80211 already (need to) hold
the RTNL. As such, there's little point in having another
four mutexes for various parts of the code, they just cause
lock ordering issues (and much of the time, the RTNL and a
few of the others need thus be held.)
Simplify all this by getting rid of the extra four mutexes
and just use the RTNL throughout. Only a few code changes
were needed to do this and we can get rid of a work struct
for bonus points.

Some protocols need a more reliable connection to complete
successful in reasonable time. This patch adds a user-space
API to indicate the wireless driver that a critical protocol
is about to commence and when it is done, using nl80211 primitives
NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP.
There can be only on critical protocol session started per
registered cfg80211 device.
The driver can support this by implementing the cfg80211 callbacks
.crit_proto_start() and .crit_proto_stop(). Examples of protocols
that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the
link can/should be made more reliable is up to the driver. Things
to consider are avoid scanning, no multi-channel operations, and
alter coexistence schemes.

This is the sort of thing gcc's LTO could do, but since
we don't have that yet we can also do it manually. The
advantage is reduced code, both source and binary, e.g.
on x86-64
text data bss dec hex filename
442825 56230 776 499831 7a077 cfg80211.ko (before)
441585 56230 776 498591 79b9f cfg80211.ko (after)
a reduction of ~1k.
But in order to not complicate the code move only those
functions that are simple wrappers, not those that have
functionality of their own.

Once radar detection has started it should continuously

Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.
Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.
Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.

In order to support using a different MAC address
for the P2P Device address we must first have a
P2P Device abstraction that can be assigned a MAC
address.
This abstraction will also be useful to support
offloading P2P operations to the device, e.g.
periodic listen for discoverability.
Currently, the driver is responsible for assigning
a MAC address to the P2P Device, but this could be
changed by allowing a MAC address to be given to
the NEW_INTERFACE command.
As it has no associated netdev, a P2P Device can
only be identified by its wdev identifier but the
previous patches allowed using the wdev identifier
in various APIs, e.g. remain-on-channel.
