In MFP, do not disconnect if an unprotected deauth
or disassoc was received during D3.
For that, need to configure wowlan with MFP (IS_11W_ASSOC).
Now, in case of an unprotected deauth/disassoc, the wakeup
reason returned by the firmware will be:
IWL_WAKEUP_BY_11W_UNPROTECTED_DEAUTH_OR_DISASSOC
(and not IWL_WOWLAN_WAKEUP_BY_DISCONNECTION_ON_DEAUTH
which will cause a disconnection).
Also, report this reason to cfg80211.
In another patch, the driver will send an SA query.

The firmware (later) actually uses the values even for keys
that are invalid as far as the host is concerned, later in
rekeying, and then only sets the low 48 bits since the PNs
are only 48 bits over the air. It does, however, compare the
full 64 bits later, obviously causing problems.
Remove the memset and use kzalloc instead to avoid any old
heap data leaking to the firmware. We already init all the
other fields in the struct anyway. This leaves the data set
to zero for any unused fields, so the firmware can look at
them safely even if they're not used right now.

When retrieving the queue index ("SCD SSN") from the TX response,
it's currently masked with 0xFFF. However, now that we have queues
longer than 4k, that became wrong, so make the mask depend on the
hardware family.
This fixes an issue where if we get a single frame reclaim while
in the top half of an 8k long queue, we'd reclaim-wrap the queue
twice (once on this and then again on the next non-single reclaim)
which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(),
but could have other negative side effects (such as unmapping a
frame that wasn't transmitted yet, and then taking an IOMMU fault)
as well.

After waking from D3, we set the iPN given by the firmware.
For some reason, CIPHER_SUITE_AES_CMAC was missed.
That caused copying garbage to the iPN - causing false replays.
(since 'seq' is on the stack, and the iPN from the firmware
was not copied into it, it contains garbage which later is
copied to the iPN key).

With unlimited pseudo-D3, we can get stuck here in the read if
the firmware never wakes up. All of our testing infrastructure
however will anyway give up after at most a minute, so there's
no value in that.
Limit this to about a minute to avoid getting stuck with the
RTNL held forever, which basically makes the machine unusable

finalizing worker using the deflink. With MLO, there is a need to do it
on a given link basis.

Currently, function to update beacon counter uses deflink to fetch
the beacon and then update the counter. However, with MLO, there is
a need to update the counter for the beacon in a particular link.
Add support to use link_id in order to fetch the beacon from a particular
link data during beacon update counter.

Aloka originally suggested that puncturing should be part of
the chandef, so that it's treated correctly. At the time, I
disagreed and it ended up not part of the chandef, but I've
now realized that this was wrong. Even for clients, the RX,
and perhaps more importantly, CCA configuration needs to take
puncturing into account.
Move puncturing into the chandef, and adjust all the code
accordingly. Also add a few tests for puncturing in chandef
compatibility checking.

A DoS tool that injects loads of authentication frames made our AP
crash. The iwl_mvm_is_dup() function couldn't find the per-queue
dup_data which was not allocated.
The root cause for that is that we ran out of stations in the firmware
and we didn't really add the station to the firmware, yet we didn't
return an error to mac80211.
Mac80211 was thinking that we have the station and because of that,
sta_info::uploaded was set to 1. This allowed
ieee80211_find_sta_by_ifaddr() to return a valid station object, but
that ieee80211_sta didn't have any iwl_mvm_sta object initialized and
that caused the crash mentioned earlier when we got Rx on that station.

The code walking trip points in iwl_mvm_send_temp_report_ths_cmd()
reads the trip table passed to thermal_zone_device_register_with_trips()
in order to get the current trip temperatures, but this is not
guaranteed to work in the future, because the thermal zone will store
trip points information internally.
For this reason, make iwl_mvm_send_temp_report_ths_cmd() use
for_each_thermal_trip() as appropriate for walking trip points in a
given thermal zone.
No intentional functional impact, but it is requisite for future thermal
core improvements.

The trip table in iwl_mvm_thermal_zone_register() is populated after
passing it to thermal_zone_device_register_with_trips(), so it may be
accessed (for instance, via sysfs) before it is ready.
To prevent that from happening, modify the function to populate the
trip table before calling thermal_zone_device_register_with_trips().
Also make the code use THERMAL_TEMP_INVALID as the "invalid temperature"
value which is also meaningful for the core.

The fw_trips_index[] array in struct iwl_mvm_thermal_device is only
populated, but never read, so drop it.
Note that the iwl_mvm_send_temp_report_ths_cmd() code populating
fw_trips_index[] is questionable, because it accesses a trips table
of a thermal zone directly, which is not guaranteed to work in the
future.
No functional impact.

This is an error path and Smatch complains that "tbl_rev" is uninitialized
on this path. All the other functions follow this same patter where they
set the error code and goto out_free so that's probably what was intended
here as well.

Before sending a SESSION PROTECTION cmd the driver checks if
the link_id indicated in the time event (and for which the cmd will be
sent) is valid and exists.
Clear the te_data::link_id when FW notifies that a session protection
ended, so the check will actually fail when it should.

As described in IEEE sta 802.11-2020, table 9-30 (Address
field contents), A-MSDU address 3 should contain the BSSID
address.
In TX_CMD we copy the MAC header from skb, and skb address 3
holds the destination address, but it may not be identical to
the BSSID.
Using the wrong destination address appears to work with (most)
receivers without MLO, but in MLO some devices are checking for
it carefully, perhaps as a consequence of link to MLD address
translation.
Replace address 3 in the TX_CMD MAC header with the correct
address while retaining the skb address 3 unchanged.
This ensures that skb address 3 will be utilized later for
constructing the A-MSDU subframes.
Note that we fill in the MLD address, but the firmware will do the
necessary translation to link address after encryption.

For channel contexts, mac80211 currently uses the cfg80211
chandef struct (control channel, center freq(s), width) to
define towards drivers and internally how these behave. In
fact, there are _two_ such structs used, where the min_def
can reduce bandwidth according to the stations connected.
Unfortunately, with EHT this is longer be sufficient, at
least not for all hardware. EHT requires that non-AP STAs
that are connected to an AP with a lower bandwidth than it
(the AP) advertises (e.g. 160 MHz STA connected to 320 MHz
AP) still be able to receive downlink OFDMA and respond to
trigger frames for uplink OFDMA that specify the position
and bandwidth for the non-AP STA relative to the channel
the AP is using. Therefore, they need to be aware of this,
and at least for some hardware (e.g. Intel) this awareness
is in the hardware. As a result, use of the "same" channel
may need to be split over two channel contexts where they
differ by the AP being used.
As a first step, introduce a concept of a channel request
('chanreq') for each interface, to control the context it
requests. This step does nothing but reorganise the code,
so that later the AP's chandef can be added to the request
in order to handle the EHT case described above.
