Subject: [PATCH 01/43] wifi: iwlwifi: nvm-parse: enable WiFi7 for Fm radio for
 now

We're still working out how the hardware/firmware (will) advertise
support for this - for now, assume that Fm radio supports it.

Subject: [PATCH 02/43] wifi: iwlwifi: modify new queue allocation command

Follow a new firmware API changes and update the queue allocation
command in the remove/modify cases to take the station mask and
TID instead of the queue ID.

Subject: [PATCH 03/43] wifi: iwlwifi: mvm: don't access packet before checking
 len

Currently in sniffer mode we access pkt fields before checking that
the frame has the length to access it. Fix this by moving the check
to before the access.

Subject: [PATCH 05/43] wifi: iwlwifi: mvm: replace usage of found with
 dedicated list iterator variable

To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

While at it, stop using the unnecessary _safe() variant.

Subject: [PATCH 07/43] wifi: iwlwifi: mvm: Don't use deprecated register

The CSR_HW_IF_CONFIG_REG register is no longer in use from
IWL_DEVICE_FAMILY_AX210 and on.
This register uses now for CSR_CTXT_INFO_BOOT_CTRL
which has a different meaning and a different format.
Currently we're writing to the register according to
CSR_HW_IF_CONFIG_REGs format, regardless to the device family.
This causes to miss-interpretation of the register value, as it is
parsed according to CSR_CTXT_INFO_BOOT_CTRLs format for devices
families >= IWL_DEVICE_FAMILY_AX210.
Fix this by writing to the register according to the old format
only for the relevant hardware.

Subject: [PATCH 13/43] wifi: brcmfmac: add function to unbind device to bus
 layer api

Introduce a new bus callback .remove() which will unbind the device
from the driver. This allows the common driver layer to stop handling
a device.

Subject: [PATCH 14/43] wifi: brcmfmac: add firmware vendor info in driver info

In order to determine the vendor that released a firmware image for
a specific device, the device table now sets the vendor identifier
in driver info and it is stored in struct brcmf_bus::fwvid during
probe.

Subject: [PATCH 15/43] wifi: brcmfmac: add support for vendor-specific
 firmware api

The driver is being used by multiple vendors who develop the firmware
api independently. So far the firmware api as used by the driver has
not diverged (yet). This change adds framework for supporting multiple
firmware apis. The vendor-specific support code has to provide a number
of callback operations. Right now it is only attach and detach callbacks
so no real functionality as the api is still common. This code only
adds WCC variant anyway, which is selected for all devices right now.
The vendor-specific part will be built in a separate module when the
driver is configured to be built as a module through Kconfig, ie. when
CONFIG_BRCMFMAC=m.

From f74f1ec22dc232be0296739148d126e9158eadf9 Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend.vanspriel@broadcom.com>
Date: Tue, 29 Nov 2022 14:54:43 +0100
Subject: [PATCH 16/43] wifi: brcmfmac: add support for Cypress firmware api

Cypress uses the brcmfmac driver and releases firmware which will
likely diverge over time (or already has). So adding support for
handling that.

Subject: [PATCH 17/43] wifi: brcmfmac: add support Broadcom BCA firmware api

Broadcom BCA division develops its own firmware api and as such will
likely diverge over time (or already has). Add support for handling
this.

Subject: [PATCH 19/43] wifi: brcmfmac: introduce BRCMFMAC exported symbols
 namespace

Using a namespace variant to make clear it is only intended to be used
by the vendor-specific modules. The symbol will only truly export the
symbols when the driver and consequently the vendor-specific part are
built as kernel modules.

Subject: [PATCH 20/43] wifi: rtl8xxxu: Add __packed to struct rtl8723bu_c2h

This struct is used to access a sequence of bytes received from the
wifi chip. It must not have any padding bytes between the members.

This doesn't change anything on my system, possibly because currently
none of the members need more than byte alignment.

Subject: [PATCH 21/43] wifi: rtl8xxxu: Fix the channel width reporting

The gen 2 chips RTL8192EU and RTL8188FU periodically send the driver
reports about the TX rate, and the driver passes these reports to
sta_statistics. The reports from RTL8192EU may or may not include the
channel width. The reports from RTL8188FU do not include it.

Only access the c2h->ra_report.bw field if the report (skb) is big
enough.

The other problem fixed here is that the code was actually never
changing the channel width initially reported by
rtl8xxxu_bss_info_changed because the value of RATE_INFO_BW_20 is 0.

// It will iterate enabled LSMs' hooks for kernel_read_file.
// With loadpin, it hooks loadpin_read_file.
```

If SECURITY_LOADPIN_ENFORCE is enabled, doing kernel_read_file() on partial
files will be denied and return -EPERM (-1). Then, the outer API based on it,
e.g. request_partial_firmware_into_buf(), will get the error.

In the case, we cannot get the firmware stuffs right, even though there might
be no error other than a permission issue on reading a partial file. So we have
to request full firmware if SECURITY_LOADPIN_ENFORCE is enabled. It makes us
still have a chance to do early firmware work on this kind of platforms.

Subject: [PATCH 25/43] wifi: rtw89: request full firmware only once if it's
 early requested

Under some condition, we now have to do early request full firmware when
rtw89_early_fw_feature_recognize(). In this case, we can avoid requesting
full firmware twice during probing driver. So, we pass out full firmware
from rtw89_early_fw_feature_recognize() if it's requested successfully.
And then, if firmware is settled, we have no need to request full firmware
again during normal initizating flow.

Setting firmware flow is updated to be as the following.

 platform	| early recognizing 	| normally initizating
-----------------------------------------------------------------------
 deny reading 	| request full FW	| (no more FW requesting)
 partial file 	|			| (obtain FW from early pahse)
-----------------------------------------------------------------------
 able to read	| request partial FW	| async request full FW
 partial file	| (quite small chunk)	|

Subject: [PATCH 26/43] wifi: rtw89: add mac TSF sync function

If the interface is in AP/P2P GO mode, we adjust the TSF with random
offset to avoid TBTT of different vifs to overlap and collide.
For every new interface added, we adjust the value and resync for all
interfaces.

Subject: [PATCH 30/43] wifi: rtw88: print firmware type in info message

It's confusing to read two different firmware versions in the syslog
for the same device:

rtw_8822cu 2-1:1.2: Firmware version 9.9.4, H2C version 15
rtw_8822cu 2-1:1.2: Firmware version 9.9.11, H2C version 15

Print the firmware type in this message to make clear these are really
two different firmwares for different purposes:

rtw_8822cu 1-1.4:1.2: WOW Firmware version 9.9.4, H2C version 15
rtw_8822cu 1-1.4:1.2: Firmware version 9.9.11, H2C version 15

Subject: [PATCH 32/43] wifi: rtw88: Drop rf_lock

The rtwdev->rf_lock spinlock protects the rf register accesses in
rtw_read_rf() and rtw_write_rf(). Most callers of these functions hold
rtwdev->mutex already with the exception of the callsites in the debugfs
code. The debugfs code doesn't justify an extra lock, so acquire the mutex
there as well before calling rf register accessors and drop the now
unnecessary spinlock.

Subject: [PATCH 35/43] wifi: rtw88: iterate over vif/sta list non-atomically

The driver uses ieee80211_iterate_active_interfaces_atomic()
and ieee80211_iterate_stations_atomic() in several places and does
register accesses in the iterators. This doesn't cope with upcoming
USB support as registers can only be accessed non-atomically.

Split these into a two stage process: First use the atomic iterator
functions to collect all active interfaces or stations on a list, then
iterate over the list non-atomically and call the iterator on each
entry.
