058b94dc9b iwlwifi: mvm: support version 11 of wowlan statuses notification
The new version of the command has same size and layout as
version 10. It just sends corresponding station id in one
of the reserved fields. It's not used in the driver, so just
be ready to accept version 11.

79e561f0f0 iwlwifi: mvm: d3: implement RSC command version 5
In later firmware we haven't needed the TSC anyway since
we have it already (and firmware image doesn't change),
but the new version adds the ability to send down replay
counters for more than one GTK. Implement that.

We do a key iteration to program the keys, and while at it

take out the TKIP phase 1 key generation and do that in a

It's been a while that the firmware uses LONG_GROUP by default
and not LEGACY_GROUP.
Until now the firmware wrongly advertise the WOWLAN_GET_STATUS
command's version with LEGACY_GROUP, but it is now being fixed.
In order to support both firmwares, first try to get the version
number of the command with the LONG_GROUP and if the firmware
didn't advertise the command version with LONG_GROUP, try to get
the command version with LEGACY_GROUP.

e8fe3b41c3 iwlwifi: mvm: Add support for 6GHz passive scan
When doing scan while 6GHz channels are not enabled, the 6GHz band
is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands
(that will allow discovery of geographic location etc. that would
allow enabling the 6GHz channels) but there are non collocated APs
on 6GHz PSC channels these would never be discovered.

To overcome this, FW added support for performing passive UHB scan
in case no APs were discovered during scan on the 2GHz and 5GHz
channels.

Add support for enabling such scan when the following conditions are
met:

- 6GHz channels are supported but not enabled by regulatory.
- Station interface is not associated or less than a defined time
  interval passed from the last resume or HW reset flows.
- At least 4 channels are included in the scan request
- The scan request includes the widlcard SSID.
- At least 50 minutes passed from the last 6GHz passive scan.

708a39aaca iwlwifi: mvm: don't send commands during suspend\resume transition
D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).

There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.

To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

The latter is better because test_bit is atomic. Also
add a call to synchronize_net after we set the bit to
make sure that all the new Tx see the bit before we

a05829a722 cfg80211: avoid holding the RTNL when calling the driver
Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.

Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).

Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

In D3 resume flow, avoid the following race where sending
packets before updating the sequence number (sequence
number received from the wowlan status command response):
Thread 1:
__iwl_mvm_resume clears IWL_MVM_STATUS_IN_D3 and is cut
by thread 2 before reaching iwl_mvm_query_wakeup_reasons.
Thread 2:
iwl_mvm_mac_itxq_xmit calls iwl_mvm_tx_skb since
IWL_MVM_STATUS_IN_D3 is not set using a wrong sequence number.
Thread 1:
__iwl_mvm_resume continues and calls iwl_mvm_query_wakeup_reasons
updating the sequence number received from the firmware.

The next packet that will be sent now will cause sysassert 0x1096.

Fix the bug by moving 'clear IWL_MVM_STATUS_IN_D3' to after
sending the wowlan status command and updating the sequence
number.

This command should be used only when there's a real client station.
Currently it works, but since soon the driver will stop actually having
an auxiliary station by default, and this command requires _some_ valid
station, it needs to be removed from this flow.

efa40c7ef6 iwlwifi: mvm: fix suspicious rcu usage warnings
mvm mutex isn't held by iwl_mvm_set_aes_rx_seq or it caller.
iee80211_local->key_mtx is held, but that is internal to mac80211.

The same applies to iwl_mvm_wowlan_program_keys.

Just hold rcu_read_lock, even though we are protected, the penalty
isn't that bad.

Fix this by keeping a status flag for D3 instead of checking for

This reduces occurrences of checks for IWL_UCODE_WOWLAN to just the
code that actually loads the image or deals with it in other ways.

6ce1e5c0c2 iwlwifi: support per-platform antenna gain
TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.
