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.

When we split the wiphy dump because it got too large, I added a
comment and asked that all new command advertising be done only
for userspace clients capable of receiving split data, in order
to not break older ones (which can't use the new commands anyway)
This mostly worked, and we haven't added many new commands, but
I occasionally get patches that modify the wrong place.
Make this easier to detect and understand by splitting out the
old commands to a separate function that makes it more clear it
should never be modified again.

As part of interface combination checking, verify any new
interface's beacon intervals. In fact, just always add the
beacon interval since that's harmless.
With this patch, mac80211 is prepared for drivers that set
the min_beacon_int_gcd parameter in interface combinations.

Remove the pointless checking against interface combinations in
the initial basic beacon interval validation, that currently isn't
taking into account radar detection or channels properly. Instead,
just validate the basic range there, and then delay real checking
to the interface combination validation that drivers must do.
This means that drivers wanting to use the beacon_int_min_gcd will
now have to pass the new_beacon_int when validating the AP/mesh
start.

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.

Add a helper using wdev to check if interface is running. This
deals with both non-netdev and netdev interfaces. In struct
wireless_dev replace 'p2p_started' and 'nan_started' by
'is_running' as those are mutually exclusive anyway, and unify
all the code to use wdev_running().

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.

On a disconnect request from userspace, cfg80211 currently calls
called rdev_disconnect() only in case that 'current_bss' was set,
i.e. connection had been established.
Change this to allow the userspace call to succeed and call the
driver's disconnect() method also while the connection attempt is
in progress, to be able to abort attempts.

Currently mac80211 determines whether HW does fragmentation
by checking whether the set_frag_threshold callback is set
or not.
However, some drivers may want to set the HW fragmentation
capability depending on HW generation.
Allow this by checking a HW flag instead of checking the
callback.

When the driver sets the SUPPORTS_REORDERING_BUFFER hardware flag,
the debugfs data for RX aggregation sessions won't even indicate
that a session is open. Since the previous fix to store the dialog
token separately, we can indicate that it's open and add the token
so that there's at least some data (ssn is not available.)

On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag,
we crash when the peer sends an AddBA request while we already
have a session open on the seame TID; this is because on those
drivers, the tid_agg_rx is left NULL even though the session is
valid, and the agg_session_valid bit is set.
To fix this, store the dialog tokens outside the tid_agg_rx to
be able to compare them to the received AddBA request.

This commit provides a mechanism for the host drivers to advertise the
support for different beacon intervals among the respective interface
combinations in a group, through NL80211_IFACE_COMB_BI_MIN_GCD (u32).
This value will be compared against GCD of all beaconing interfaces of
matching combinations.
If the driver doesn't advertise this value, the old behaviour where
all beacon intervals must be identical is retained.
If it is specified, then any beacon interval for an interface in the
interface combination as well as the GCD of all active beacon intervals
in the combination must be greater or equal to this value.

Michael Braun reported that when trying to inject A-MSDUs over
monitor interfaces, the frame doesn't come out right since the
QoS header A-MSDU bit is overwritten.
Rather than adding that bit specifically simply preserve those
bits that we don't set here, since we typically get here with
a zeroed-out QoS header anyway.

This patch adds filtering for multicast data packets on AP_VLAN
interfaces that have no authorized station connected and changes
filtering on AP interfaces to not count stations assigned to
AP_VLAN interfaces.
This saves airtime and avoids waking up other stations currently
authorized in this BSS. When using WPA, the packets dropped could
not be decrypted by any station.
The behaviour when there are no AP_VLAN interfaces is left unchanged.
When there are AP_VLAN interfaces, this patch
1. adds filtering multicast data packets sent on AP_VLAN interfaces
that have no authorized station connected.
No filtering happens on 4addr AP_VLAN interfaces.
2. makes filtering of multicast data packets sent on AP interfaces
depend on the number of authorized stations in this bss not
assigned to an AP_VLAN interface.
Therefore, a new num_mcast_sta counter is added for AP_VLAN interfaces.
The existing one for AP interfaces is altered to not track stations
assigned to an AP_VLAN interface.
The new counter is exposed in debugfs.

Checking for num_mcast_sta in __ieee80211_request_smps_ap() is
unnecessary as sta list will be empty in this case anyway, so
the list iteration will just exit immediately. Since this isn't
a "hot" code path, it doesn't really matter, and the next patch
will redefine num_mcast_sta to make this check invalid.

Instead of building the multi-channel ops at runtime, declare
the common ops with a macro and build both that way, so that
the multi-channel ops can also be const.
As a side effect, due to the removed code, this decreases the
size of the module (while shifting data from .bss to .text
due to the newly added const).

sta_info_get_bss() is equivalent to sta_info_get() in the
mesh case, since sta->sdata->bss will be NULL (it's only
set for AP/AP_VLAN interfaces.) Thus, the mesh check here
isn't actually needed - remove it.

Some boards have an entirely passive RGB to VGA bridge, based on DACs
implemented by resistor ladders.
Those might or might not have an i2c bus routed to the VGA connector in
order to access the screen EDIDs.
Add a bridge that doesn't do anything but expose the modes available on the
screen, either based on the EDIDs if available, or based on the XGA
standards.

dma_buf may live a long time, longer than the last direct user of the
driver. We already hold a reference to the owner module (that prevents
the object code from disappearing), but there is no reference to the
drm_dev - so the pointers to the driver backend themselves may vanish.
v2: Resist temptation to fix the bug in armada_gem.c not setting the
correct flags on the exported dma-buf (it should pass the flags through
and not be arbitrarily setting O_RDWR).
Use a common wrapper for exporting the dmabuf and acquiring the
reference to the drm_device.

dma_buf_export() adds a reference to the owning module to the dmabuf (to
prevent the driver from being unloaded whilst a third party still refers
to the dmabuf). However, drm_gem_prime_export() was passing its own
THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right
owner from the device->fops instead.
v2: Use C99 initializers to zero out unset elements of
dma_buf_export_info
v3: Extract the right module from dev->fops.
