To support multiple vifs, fw need more information of each role.

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) |

// 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.

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.

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.

The Medion Lifetab S10346 is a x86 tablet which ships with Android x86 as

As usual the Medion Lifetab S10346's DSDT contains a bunch of extra I2C
devices which are not actually there, causing various resource conflicts.

The dev_err_probe() has (at least) following benefits over dev_err()
when printing an error print for a failed function call at a device
driver probe:
- Omit error level print if error is 'EPRBE_DEFER'
- Standardized print format for returned error
- return the error value allowing shortening calls like:
if (ret) {
dev_err(...);
return ret;
}
to
if (ret)
return dev_err_probe(...);
Convert the ROHM BD71828, ROHM BD718x7 and ROHM BD9576 core drivers to
use the dev_err_probe() when returned error is not hard-coded constant.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

Following by the below discussion, there's the potential UAF issue
between regulator and mfd.
https://lore.kernel.org/all/20221128143601.1698148-1-yangyingliang@huawei.com/
From the analysis of Yingliang
CPU A |CPU B
mt6370_probe() |
devm_mfd_add_devices() |
|mt6370_regulator_probe()
| regulator_register()
| //allocate init_data and add it to devres
| regulator_of_get_init_data()
i2c_unregister_device() |
device_del() |
devres_release_all() |
// init_data is freed |
release_nodes() |
| // using init_data causes UAF
| regulator_register()
It's common to use mfd core to create child device for the regulator.
In order to do the DT lookup for init data, the child that registered
the regulator would pass its parent as the parameter. And this causes
init data resource allocated to its parent, not itself. The issue happen
when parent device is going to release and regulator core is still doing
some operation of init data constraint for the regulator of child device.
To fix it, this patch expand 'regulator_register' API to use the
different devices for init data allocation and DT lookup.

The addition of 3WIRE support would affect MOSI direction even
when still in standard (4 wire) mode. This can lead to MOSI being
at an invalid logic level when a device driver sets an SPI
message with a NULL tx_buf.
spi.h states that if tx_buf is NULL then "zeros will be shifted
out ... " If MOSI is tristated then the data shifted out is subject
to pull resistors, keepers, or in the absence of those, noise.
This issue came to light when using spi-gpio connected to an
ADS7843 touchscreen controller. MOSI pulled high when clocking
MISO data in caused the SPI device to interpret this as a command
which would put the device in an unexpected and non-functional
state.

Instead of performing custom hash calculations, rely on FW that returns
unique identifier to every created SA. That identifier is Xarray ready,
which provides better semantic with efficient access.
In addition, store both TX and RX SAs to allow correlation between event
generated by HW when limits are armed and XFRM states.

Software implementation of IPsec skips encryption of packets in TX
path if no matching policy is found. So align HW implementation to
this behavior, by requiring matching reqid for offloaded policy and
SA.

Add the following statistics:
RX successfully IPsec flows:
ipsec_rx_pkts : Number of packets passed Rx IPsec flow
ipsec_rx_bytes : Number of bytes passed Rx IPsec flow
Rx dropped IPsec policy packets:
ipsec_rx_drop_pkts: Number of packets dropped in Rx datapath due to IPsec drop policy
ipsec_rx_drop_bytes: Number of bytes dropped in Rx datapath due to IPsec drop policy
TX successfully encrypted and encapsulated IPsec packets:
ipsec_tx_pkts : Number of packets encrypted and encapsulated successfully
ipsec_tx_bytes : Number of bytes encrypted and encapsulated successfully
Tx dropped IPsec policy packets:
ipsec_tx_drop_pkts: Number of packets dropped in Tx datapath due to IPsec drop policy
ipsec_tx_drop_bytes: Number of bytes dropped in Tx datapath due to IPsec drop policy
The above can be seen using:
ethtool -S <ifc> |grep ipsec

Flow steering API separates newly created rules based on their
match criteria. Right now, all IPsec tables are created with one
group and suffers from not-optimal FS performance.
Count number of different match criteria for relevant tables, and
set proper value at the table creation.

In packet offload mode, the HW is responsible to handle ESP headers,
SPI numbers and trailers (ICV) together with different logic for
RX and TX paths.
In order to support packet offload mode, special logic is added
to flow steering rules.
