f7385a2024 wifi: wfx: allow to send frames during ROC
Until now, all the traffic was blocked during scan operation. However,
scan operation is going to be used to implement Remain On Channel (ROC).
In this case, special frames (marked with IEEE80211_TX_CTL_TX_OFFCHAN)
must be sent during the operation.

These frames need to be sent on the virtual interface #2. Until now,
this interface was only used by the device for internal purpose. But
since API 3.9, it can be used to send data during scan operation (we
hijack the scan process to implement ROC).

Thus, we need to change a bit the way we match the frames with the
interface.

Fortunately, the frames received during the scan are marked with the
correct interface number. So there is no change to do on this part.

04106ec5bb wifi: wfx: scan_lock is global to the device
Currently, one scan_lock is associated to each vif. However, concurrent
scan on vifs is explicitly prohibited by the device. Currently,
scan_lock is associated with a vif but it is always locked with
conf_mutex (there is a case where conf_mutex is not associated to
scan_lock but scan_lock is tested on all interfaces). So concurrent scan
on vifs cannot happen.

So, this patch relocate scan_lock to the device and simplify the code.

f091bcb62d wifi: wfx: simplify exclusion between scan and Rx filters
The device ignore the rx filters during the scan operation.
wfx_configure_filter() acquires scan_lock to reflect this restriction.
However, it is not really necessary since mac80211 don't try to
configure Rx filters during scan.

However, the things are changing. The scan operation is going to be used
to implement remain-on-channel. In this case, wfx_configure_filter() can
be called during the scan. Currently, this scenario generate a delay
that end with a timeout in the upper layers. For the final user, some
scenario of the EasyConnect specification end with a failure.

So, avoid acquiring the scan_lock and just return.

8b27aed225 wifi: wfx: fix power_save setting when AP is stopped
The WF200 allow to start two network interfaces (one AP, one station) on
two different channels. Since magic does not exist, it only works if the
station interface enables power save.

Thus, the driver detects this case and enforce power save as necessary.

This patch fixes the case where the AP interface is stopped and it is no
more necessary to enforce power saving on the station interface.

====================
wireless-next patches for v6.7

The first pull request for v6.7, with both stack and driver changes.
We have a big change how locking is handled in cfg80211 and mac80211
which removes several locks and hopefully simplifies the locking
overall. In drivers rtw89 got MCC support and smaller features to
other active drivers but nothing out of ordinary.

Major changes:

cfg80211
 - remove wdev mutex, use the wiphy mutex instead
 - annotate iftype_data pointer with sparse
 - first kunit tests, for element defrag
 - remove unused scan_width support

mac80211
 - major locking rework, remove several locks like sta_mtx, key_mtx
   etc. and use the wiphy mutex instead
 - remove unused shifted rate support
 - support antenna control in frame injection (requires driver support)
 - convert RX_DROP_UNUSABLE to more detailed reason codes

rtw89
 - TDMA-based multi-channel concurrency (MCC) support

iwlwifi
 - support set_antenna() operation
 - support frame injection antenna control

ath12k
 - WCN7850: enable 320 MHz channels in 6 GHz band
 - WCN7850: hardware rfkill support
 - WCN7850: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS to make scan faster

ath11k
 - add chip id board name while searching board-2.bin

453a62a3ee wifi: ath12k: fix debug messages
In ath12k the debug messages were broken, no matter setting what value to the
debug_mask module parameter would not get the debug messages printed. The issue
is that __ath12k_dbg() uses dev_dbg() to print the debug messages which requires either enabling
CONFIG_DYNAMIC_DEBUG or DEBUG symbol in the driver.

ath12k is supposed to use debug_mask module to control whether debug messages
are printed or not. Using both CONFIG_DYNAMIC_DEBUG and debug_mask parameter
does not make any sense so switch to using dev_printk(), just like ath11k does.
Now it's enough just to debug_mask module parameter to get the debug messages.

77f1ee6fd8 wifi: ath11k: fix Tx power value during active CAC
Tx power is fetched from firmware's pdev stats. However, during active
CAC, firmware does not fill the current Tx power and sends the max
initialised value filled during firmware init. If host sends this power
to user space, this is wrong since in certain situations, the Tx power
could be greater than the max allowed by the regulatory. Hence, host
should not be fetching the Tx power during an active CAC.

Fix this issue by returning -EAGAIN error so that user space knows that there's
no valid value available.

69fcb52590 wifi: ath11k: fix CAC running state during virtual interface start
Currently channel definition's primary channel's DFS CAC time
as well as primary channel's state i.e usable are used to set
the CAC_RUNNING flag for the ath11k radio structure. However,
this is wrong since certain channel definition are possbile
where primary channel may not be a DFS channel but, secondary
channel is a DFS channel. For example - channel 36 with 160 MHz
bandwidth.
In such cases, the flag will not be set which is wrong.

Fix this issue by using cfg80211_chandef_dfs_usable() function
from cfg80211 which return trues if at least one channel is in
usable state.

While at it, modify the CAC running debug log message to print
the CAC time as well in milli-seconds.

d876188ab8 wifi: ath10k: indicate to mac80211 scan complete with aborted flag for ATH10K_SCAN_STARTING state
Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash
   immediately after step 1.

result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)

reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath10k_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath10k_scan_finish() which is called from
ath10k_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH10K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.

Indicate scan complete with aborted flag to mac80211 for
ATH10K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.

170c75d43a wifi: ath10k: Don't touch the CE interrupt registers after power up
As talked about in commit d66d24ac30 ("ath10k: Keep track of which
interrupts fired, don't poll them"), if we access the copy engine
register at a bad time then ath10k can go boom. However, it's not
necessarily easy to know when it's safe to access them.

The ChromeOS test labs saw a crash that looked like this at
shutdown/reboot time (on a chromeos-5.15 kernel, but likely the
problem could also reproduce upstream):

Though there's no known way to reproduce the problem, it makes sense
that it would be the same issue where we're trying to access copy
engine registers when it's not allowed.

Let's fix this by changing how we "disable" the interrupts. Instead of
tweaking the copy engine registers we'll just use disable_irq() and
enable_irq(). Then we'll configure the interrupts once at power up
time.

972754bfee wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware crash
In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has
been disabled for size reduction. Currently ath12k always enables EHT PHY
mode during vdev start but with the special firmware that will cause a
firmware crash during vdev start in firmware initialisation. This is
because the firmware will use the EHT mode to allocate resources but as
the EHT mode is not available in the firmware, there's an internal
conflict and the firmware will crash.

To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware
supports EHT. If EHT is not supported downgrade the PHY mode to HE
(IEEE 802.11ax).

This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled
for QCN9274, then eht_cap->has_eht will always set for it, and the logic
of this patch will not take effect and the PHY mode will not down grade
for it.

1e55298a63 wifi: ath12k: do not drop data frames from unassociated stations
>From 'IEEE Std 802.11-2020 section 11.3.4.1':
If STA A in an infrastructure BSS receives a Class 2 or Class 3 frame
from STA B that is not authenticated with STA A
(i.e., the state for STA B is State 1), STA A shall discard the frame.
If the frame has an individual address in the Address 1 field,
the MLME of STA A shall send a Deauthentication frame to STA B.

When data frames from unassociated stations are received by an AP,
the AP is supposed to send a deauthentication/disassociation frame with
reason code "Class 2 frame received from nonauthenticated STA" or
"Class 3 frame received from nonassociated STA".

But ath12k AP doesn't send deauthentication/disassociation frames,
when it receives data frames from unassociated stations.

The ath12k driver drops the data frames from unassociated
station and the upper layer(mac80211/hostapd) is not aware of such event.
Hence deauthentication/disassociation frame is not sent to that
particular station by the AP.

To address this issue, allow the data frames from the
unassociated stations to reach mac80211 so that mac80211 can send
NL80211_CMD_UNEXPECTED_FRAME event to userspace(hostapd) and hostapd
upon receiving the event will send the deauthentication/disassociation
frame with proper reason code.

The data frame from unassociated stations gets dropped in mac80211.
