ath.git fixes for 6.10. Two fixes for user reported regressions in
ath11k. One dependency fix and one error path fix.
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).

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines,

suspended (Ilpo Järvinen)
- Clear Secondary Status errors after enumeration since Master Aborts
and Unsupported Request errors are an expected part of enumeration
(Vidya Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout

CXL Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the
device supports, in addition to doing so if the size is >2GB

Cassel)
Cadence PCIe controller driver:

- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it
was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)

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.

Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.
coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().
sprintf() will be converted as weel if they have.

Currently host relies on CE interrupts to get notified that
the service ready message is ready. This results in timeout
issue if the interrupt is not fired, due to some unknown
reasons. See below logs:
[76321.937866] ath10k_pci 0000:02:00.0: wmi service ready event not received
...
[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.

Currently ath10k defines the following struct:
struct wmi_start_scan_tlvs {
u8 tlvs[0];
} __packed;
Per the guidance in [1] this should be a flexible array. However, a
direct replace to u8 tlvs[] results in the compilation error:
flexible array member in a struct with no named members
This is because C99 6.7.2.1 (16) requires that a structure containing
a flexible array member must have more than one named member.
So rather than defining a separate struct wmi_start_scan_tlvs which
contains the flexible tlvs[] array, just define the tlvs[] array where
struct wmi_start_scan_tlvs is being used.

Per the guidance in [1] this should be a flexible array. However there

To satisfy this requirement, follow the guidance from [2] and wrap the
array in a union which contains both the flexible array and a single
instance of the underlying struct. Since the footprint of the struct
is unchanged, no additional driver changes are required.

Broadcast action frames are needed for the Device Provisioning
Protocol (DPP) for Presence and PKEX Exchange requests. Currently
just ath9k has this capability so this is being enabled for
ath10k (for at least one hardware variant).
Add a new capability flag in ath10k_hw_params to indicate support
for receiving multicast action frames. This bit is then checked
when configuring the RX filter and (if set) multicast action frame
registration is enabled.
Until more hardware can be tested only the "qca6174 hw3.2" variant
is enabling this feature.
Note: I went ahead and removed the 'changed_flags' mask operation
since it had no effect, that parameter was not being used anywhere.

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.
This pull request got delayed because we were waiting for the wireless
tree pull requested processed first and after that we merged wireless
into wireless-next to avoid several conflicts in the stack.
When pulling this there's one conflict in drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c:
<<<<<<< HEAD
static int cfg80211_rtw_change_beacon(struct wiphy *wiphy,

Take the latter hunk which uses struct cfg80211_ap_update.
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

====================
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

Use convenient 'list_count_nodes()' in 'ath10k_peer_create()',
thus making the latter a bit smaller and simpler.

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.

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.

Use 'kstrtoul_from_user()', 'kstrtobool_from_user()' and
'kstrtoint_from_user()' where appropriate and thus avoid
some code duplication.
