e665988be2 brcmfmac: support monitor frames with the hardware/ucode header
So far there were two monitor frame formats:
1) 802.11 frames (with frame (sub)type & all addresses)
2) 802.11 frames with the radiotap header

Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in
discovering a new format being used. It seems (almost?) identical to the
one known from ucode used in SoftMAC devices which is most likely the
same codebase anyway.

While new firmwares will /announce/ radiotap header support using the
"rtap" fw capability string it seems no string was added for the new
ucode header format.

All above means that:
1) We need new format support when dealing with a received frame
2) A new feature bit & mapping quirks have to be added manually

As for now only an empty radiotap is being created. Adding support for
extracting some info (band, channel, signal, etc.) is planned for the
future.

3ef005b82e brcmfmac: add bphy_err() and use it in the cfg80211.c

1) Should be the best choice with wiphy already created
2) Uses dev_err() which allows identifying error-affected device

8602e62441 brcmfmac: pass bus to the __brcmf_err() in pcie.c
This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.

All bus files should follow & get updated similarly (soon).

5cc898fbcb brcmfmac: modify __brcmf_err() to take bus as a parameter
So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).

This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

cdb78e5af4 ath10k: fix hw-restart crash inject mode for WCN3990
The hw-restart crash inject mode is a special mode, where
there is no crash generated in the firmware, but instead
the driver restarts the firmware. In order to restart WCN3990
firmware, the driver needs to send qmi_wlan_disable message
followed by the qmi_wlan_enable message to the WCN3990 firmware.

Currently the qmi_wlan_disable message is not sent to
the WCN3990 firmware when hw-restart crash is injected,
which causes the firmware to crash when the driver sends
qmi_wlan_enable message during ath10k_restart.

Send qmi_wlan_disable to the WCN3990 firmware when the
hw-restart crash is injected via debugfs.

4b6e9f3fe1 ath9k: eeprom: Use scnprintf instead of snprintf
Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.

1) Uses of size += snprintf(buf, SIZE - size, fmt, ...)  In this case,
if snprintf would have written more characters than what the buffer
size (SIZE) is, then size will end up larger than SIZE. In later uses
of snprintf, SIZE - size will result in a negative number, leading to
problems. Note that size might already be too large by using size =
snprintf before the code reaches a case of size += snprintf.

2) If size is ultimately used as a length parameter for a copy back to
user space, then it will potentially allow for a buffer overflow and
information disclosure when size is greater than SIZE. When the size is
used to index the buffer directly, we can have memory corruption. This
also means when size = snprintf... is used, it may also cause problems
since size may become large. Copying to userspace is mitigated by the
HARDENED_USERCOPY kernel configuration.

The solution to these issues is to use scnprintf which returns the number
of characters actually written to the buffer, so the size variable will
never exceed SIZE.

5b9030cee1 ath10k: Set DMA address mask to 35 bit for WCN3990
WCN3990 is a 37-bit target but can address memory range
only upto 35 bits. The 36th bit is used to control the
smmu/iommu translation and the 37th bit is used by the
internal bus masters to access the wifi subsystem internal
SRAM. With the DMA mask set to 37i-bit, the host driver
can get 37-bit dma address, which leads to incorrect
address access in the target.

Hence the host driver can used addresses upto 35-bit
for WCN3990. Fix the dma mask for wcn3990 to 35-bit,
instead of 37-bit.

few more delays during initialization. Implement this workaround.

dbf592f3d1 iwlwifi: mvm: fix RFH config command with >=10 CPUs
If we have >=10 (logical) CPUs, our command size exceeds the
internal buffer size and the command fails; fix that by using
IWL_HCMD_DFL_NOCOPY for the command that's allocated anyway.

While at it, also fix the leak of cmd, and use struct_size()
to calculate its size.

New fields were added to struct iwl_fw_ini_region_cfg.
add those field and apply the changes the result from this change

offset field is used to differentiate between the different LMACs
and any memory access to the region addresses should be
base_addr + offset.

A fifo struct is to hold the meta data needed for fifo regions

Also move range_data_size and num_of_ranges into a struct under the
union to be aligned to the struct in the FW.

Hiding the HE radiotap data for further processing of the SKB just
caused another bug when adding the L-SIG data. Simply stop doing
this and adjust the skb->data pointer accordingly when we need to
get the 802.11 header.

While at it, also verify and fix the data alignment, we need to add
2 bytes padding with the vendor data to ensure the whole length of
all radiotap headers is a multiple of 4.

0ec7bfb26a iwlwifi: dbg_ini: remove redundant dram buffer allocation
There are several flows in that can cause redundant allocation.

In case the driver reaches the maximum amount of blocks allowed, it
allocates the buffer and only then checks if it reached the maximum
amount of blocks and return without freeing the buffer,
causing a memory leak.

Solve this by moving the check of the amount of buffers being used
before the allocation.

In case there was an assert, the apply points are being reused,
causing that for each assert, the driver allocates a new redundant
buffer.

Solve this by adding a new is_alloc field to indicate if the driver
already allocated memory for the requested buffer.

Also, split iwl_fw_dbg_buffer_allocation function into
iwl_fw_dbg_buffer_allocation and iwl_fw_dbg_buffer_apply
to increase the clearity of the flow.
