==================
ath.git patches for v6.17

All ath drivers:
Add "#include <linux/export.h>" to all files that use EXPORT_SYMBOL()
to fix a newly introduced 'make W=1' check. Note that check has
subsequently been changed to only test when W=2, but keep the fixes to
suppress the warning for 'make W=2'.

ath12k:
Properly handle scan requests on multi-radio wiphy devices.
Perform the usual set of bug fixes and cleanups.

b74947b4f6 wifi: cfg80211/mac80211: Add support to get radio index
Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.

To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM

By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

dc9c4252fe wifi: ath10k: Avoid vdev delete timeout when firmware is already down
In some scenarios, the firmware may be stopped before the interface is
removed, either due to a crash or because the remoteproc (e.g., MPSS)
is shut down early during system reboot or shutdown.

This leads to a delay during interface teardown, as the driver waits for
a vdev delete response that never arrives, eventually timing out.

Example (SNOC):
$ echo stop > /sys/class/remoteproc/remoteproc0/state
[ 71.64] remoteproc remoteproc0: stopped remote processor modem
$ reboot
[ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108
[ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108
[...]
[ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response

To avoid this, skip waiting for the vdev delete response if the firmware is
already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how
`ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

1650d32b92 ath10k: snoc: fix unbalanced IRQ enable in crash recovery
In ath10k_snoc_hif_stop() we skip disabling the IRQs in the crash
recovery flow, but we still unconditionally call enable again in
ath10k_snoc_hif_start().

We can't check the ATH10K_FLAG_CRASH_FLUSH bit since it is cleared
before hif_start() is called, so instead check the
ATH10K_SNOC_FLAG_RECOVERY flag and skip enabling the IRQs during crash
recovery.

This fixes unbalanced IRQ enable splats that happen after recovering from
a crash.

8add2b8d72 wifi: ath10k: Don't use %pK through printk
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

b41f96ecb9 wifi: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/net/wireless to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

En passant several whitespace changes are done to make indentation
consistent in the struct initializers.

In order to update the right link information, call the update
rate_control_rate_update() with the right link_sta, and then
pass that through to the driver's sta_rc_update() method. The
software rate control still doesn't support it, but that'll be
skipped by not having a rate control ref.

Since it now operates on a link sta, rename the driver method.

95c38953cb wifi: ath10k: avoid NULL pointer error during sdio remove
When running 'rmmod ath10k', ath10k_sdio_remove() will free sdio
workqueue by destroy_workqueue(). But if CONFIG_INIT_ON_FREE_DEFAULT_ON
is set to yes, kernel panic will happen:
Call trace:
 destroy_workqueue+0x1c/0x258
 ath10k_sdio_remove+0x84/0x94
 sdio_bus_remove+0x50/0x16c
 device_release_driver_internal+0x188/0x25c
 device_driver_detach+0x20/0x2c

This is because during 'rmmod ath10k', ath10k_sdio_remove() will call
ath10k_core_destroy() before destroy_workqueue(). wiphy_dev_release()
will finally be called in ath10k_core_destroy(). This function will free
struct cfg80211_registered_device *rdev and all its members, including
wiphy, dev and the pointer of sdio workqueue. Then the pointer of sdio
workqueue will be set to NULL due to CONFIG_INIT_ON_FREE_DEFAULT_ON.

After device release, destroy_workqueue() will use NULL pointer then the
kernel panic happen.

Call trace:

Need to call destroy_workqueue() before ath10k_core_destroy(), free
the work queue buffer first and then free pointer of work queue by
ath10k_core_destroy(). This order matches the error path order in
ath10k_sdio_probe().

No work will be queued on sdio workqueue between it is destroyed and
ath10k_core_destroy() is called. Based on the call_stack above, the
reason is:
Only ath10k_sdio_sleep_timer_handler(), ath10k_sdio_hif_tx_sg() and
ath10k_sdio_irq_disable() will queue work on sdio workqueue.
Sleep timer will be deleted before ath10k_core_destroy() in
ath10k_hif_power_down().
ath10k_sdio_irq_disable() only be called in ath10k_hif_stop().
ath10k_core_unregister() will call ath10k_hif_power_down() to stop hif
bus, so ath10k_sdio_hif_tx_sg() won't be called anymore.

bca8bc0399 wifi: mac80211: handle ieee80211_radar_detected() for MLO
Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.

Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.

Hence, in order to support DFS with MLO, do the following changes -
  * Add channel context conf pointer as an argument to the function
    ieee80211_radar_detected(). During MLO, drivers would have to pass on
    which channel context conf radar is detected. Otherwise, drivers could
    just pass NULL.
  * ieee80211_radar_detected() will iterate over all channel contexts
    present and
  	* if channel context conf is passed, only mark that as radar
  	  detected
  	* if NULL is passed, then mark all channel contexts as radar
  	  detected
  	* Then as usual, schedule the radar detected work.
  * In the worker, go over all the contexts again and for all such context
    which is marked with radar detected, cancel the ongoing CAC by calling
    ieee80211_dfs_cac_cancel() and then notify cfg80211 via
    cfg80211_radar_event().
  * To cancel the CAC, pass the channel context as well where radar is
    detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
    canceled only on the links using the provided context, leaving other
    links unaffected.

This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

2c92ca849f tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

6d67d18014 wifi: ath10k: do not always wait for MSA_READY indicator
The ath10k driver waits for an "MSA_READY" indicator
to complete initialization. If the indicator is not

Oddly, it seems safe to NOT wait for the indicator, and
proceed immediately when QMI_EVENT_SERVER_ARRIVE.

  However with so many deployed devices, "might be ok" isn't a strong

5abf259772 wifi: ath10k: support board-specific firmware overrides
Different Qualcomm platforms using WCN3990 WiFI chip use SoC-specific
firmware versions with different features. For example firmware for
SDM845 doesn't use single-chan-info-per-channel feature, while firmware
for QRB2210 / QRB4210 requires that feature. Allow board DT files to
override the subdir of the fw dir used to lookup the firmware-N.bin file
decribing corresponding WiFi firmware.

For example:

- ath10k/WCN3990/hw1.0/wlanmdsp.mbn,
  ath10k/WCN3990/hw1.0/firmware-5.bin: main firmware files, used by default

- ath10k/WCN3990/hw1.0/qcm2290/wlanmdsp.mbn,
  ath10k/WCN3990/hw1.0/qcm2290/firmware-5.bin: SoC specific firmware
    with different signature and feature bits

Note, while board files lookup uses the same function and thus it is
possible to provide board-specific board-2.bin files, this is not
required in 99% of cases as board-2.bin already contains a way to
provide board-specific data with finer granularity than DT overrides.

...
[76322.016738] ath10k_pci 0000:02:00.0: Could not init core: -110

And finally it causes WLAN interface bring up failure.

Change to give it one more chance here by polling CE rings,
before failing directly.
