If cfg80211 is providing extraie's for a scanning process then ath12k will
copy that over to the firmware. The extraie.len is a 32 bit value in struct
element_info and describes the amount of bytes for the vendor information
elements.
The problem is the allocation of the buffer. It has to align the TLV
sections by 4 bytes. But the code was using an u8 to store the newly
calculated length of this section (with alignment). And the new
calculated length was then used to allocate the skbuff. But the actual
code to copy in the data is using the extraie.len and not the calculated
"aligned" length.
The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled
was 264 bytes during tests with a wifi card. But it only allocated 8
bytes (264 bytes % 256) for it. As consequence, the code to memcpy the
extraie into the skb was then just overwriting data after skb->end. Things
like shinfo were therefore corrupted. This could usually be seen by a crash
in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus
address).

RX full flags are raised if certain types of RX FIFO are full, and then
drop all following MPDU of AMPDU. In order to resume to receive MPDU
when RX FIFO becomes available, we clear the register bits by the
commit a0d99ebb3ecd ("wifi: rtw89: initialize DMA of CMAC"). But, 8852AE
needs more settings to support this. To quickly fix disconnection problem,
revert the behavior as before.

WiFi 7 chips doesn't have static const tables defined in driver. If tables
aren't loaded properly from firmware file, driver can get NULL pointer
access exception. One way is to add the checking statements when trying to
access these tables, but I choose to check them right after loading
firmware elements from firmware file, so I don't need to add error handlers
everywhere.
Currently, the needed firmware elements of WiFi 6 chips are all zero, and
coming WiFi 7 chip will need at least BB MCU, parameters of BB and RF.
We will add them after 8922AE is verified.

The tables of BB and RF parameters are pairs of {addr, value}. Load them
and convert from little-endian to CPU order, and show the version to clear
which version we are using.
rtw89_8922ae 0000:03:00.0: Firmware element BB version: 00 04 00 00
rtw89_8922ae 0000:03:00.0: Firmware element radio A version: 00 13 00 00
rtw89_8922ae 0000:03:00.0: Firmware element NCTL version: 00 05 00 00
We use tables defined in firmware elements with higher priority than
original static const tables defined in driver, because WiFi 7 chips will
not define the tables in driver, and existing chips can possibly migrate to
the new design one by one.

In order to pack more data into firmware file, we introduce firmware
elements and append BB_MCU firmware first. The first part of new firmware
file is still unchanged firmware of WiFi CPU, so the new firmware format
can be backward compatible to old format. The new elements part consists
of ID and size basically, which can append more elements simply. To avoid
unaligned access in certain platform and be easy to read, headers of all
elements start at 16-byte aligned address.
+===========================================+
| original firmware |
| +-------------+
| | padding |
+===========================================+
| elm ID 1 | elm size | other header data |

+===================+
More detail of element header is shown below. The additional fields
'version' and 'element_priv[]' are meta data of elements, so that we can
know element version easily, and element_priv[] provide specific fields
for certain element, such as RF path index for RF parameter tables.

For existing chips, firmware is only for WiFi CPU, but WiFi 7 chips add
new hardware component BB MCU that needs firmware as well. The firmwares of
BB MCU 0/1 are also downloaded via the same path like WiFi CPU firmware,
and use the same firmware header format, so add firmware suits to access
them commonly.

A firmware with v1 format contains many sections to download. Add parser to
read section type, target address, length, checksum and so on, and then
download the section to WiFi CPU with proper location.
The additional dynamic header length named dynamic_hdr_len is used to
skip content of dynamic header containing compiler flags of firmware, which
can help to determine variant firmware build, but currently rtw89 only
use single one variant. So, just skip the content.
The layout of a WiFi CPU firmware with v1 format looks like:
+---------------------------------------+
| Header (12 words) |
+---------------------------------------+
| Section header 1 (4 words) |
| Section header 2 (4 words) |
| Section header 3 (4 words) |

Deadlock is easily happened while shutdown wlan interface such as run
"ifconfig wlan0 down".
The reason is because when ar->regd_update_work is ran, it will
call wiphy_lock(ar->hw->wiphy) in function ath12k_regd_update() which
is running in workqueue of ieee80211_local queued by ieee80211_queue_work().
Another thread from "ifconfig wlan0 down" will also accuqire the lock
by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and
then it call ieee80211_stop_device() to flush_workqueue(local->workqueue),
this will wait the workqueue of ieee80211_local finished. Then deadlock
will happen easily if the two thread run meanwhile.

When wlan interface is up, and 11d scan is sent to the firmware, then
firmware needs to spend couple of seconds to complete the 11d scan. If
normal scan from user space arrives to ath12k at this moment, then the
normal scan request is also sent to the firmware, but the scan started
event will be reported to ath12k until the 11d scan complete. When timed
out for the scan started in ath12k, ath12k stops the normal scan and the
firmware reports WMI_SCAN_EVENT_DEQUEUED to ath12k for the normal scan.
ath12k has no handler for the event and then timed out for the scan
completed in ath12k_scan_stop(), and ath12k prints the following error
message.
[ 1491.604750] ath12k_pci 0000:02:00.0: failed to receive scan abort comple: timed out
[ 1491.604756] ath12k_pci 0000:02:00.0: failed to stop scan: -110
[ 1491.604758] ath12k_pci 0000:02:00.0: failed to start hw scan: -110
Add a handler for WMI_SCAN_EVENT_DEQUEUED and then complete the scan to
get rid of the above error message.

Currently after the hardware restart triggered from the driver, the
station interface connection remains intact, since a disconnect
trigger is not sent to userspace. This can lead to a problem in
targets where the wifi mac sequence is added by the firmware.
After the target restart, its wifi mac sequence number gets reset to
zero. Hence AP to which our device is connected will receive frames
with a wifi mac sequence number jump to the past, thereby resulting
in the AP dropping all these frames, until the frame arrives with a
wifi mac sequence number which AP was expecting.
To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.

The crash is because, for WCN7850, only ab->pdev[0] is initialized, while mac_id here is
misused to retrieve pdev and it is not zero, leading to a NULL pointer access.
Fix this issue by getting pdev_id first and then use it to retrieve pdev.
Also fix some other code snippets which have the same issue.

Currently ath12k define WMI_HOST_HW_MODE_DBS_OR_SBS=5 as max hw mode
for enum wmi_host_hw_mode_config_type, it is also same for the array
ath12k_hw_mode_pri_map.
When tested with new version firmware/board data which support new
hw mode eMLSR mode with hw mode value 8, it leads overflow usage for
array ath12k_hw_mode_pri_map in function ath12k_wmi_hw_mode_caps(),
and then lead preferred_hw_mode changed to 8, and finally function
ath12k_pull_mac_phy_cap_svc_ready_ext() select the capability of hw
mode 8, but the capability of eMLSR mode report from firmware does
not support 2.4 GHz band for WCN7850, so finally 2.4 GHz band is
disabled.
Skip the hw mode which exceeds WMI_HOST_HW_MODE_MAX in function
ath12k_wmi_hw_mode_caps() helps to avoid array overflow, then the 2.4
GHz band will not be disabled.
This is to keep compatibility with newer version firmware/board data
files, this change is still needed after ath12k add eMLSR hw mode 8 in
array ath12k_hw_mode_pri_map and enum wmi_host_hw_mode_config_type,
because more hw mode maybe added in next firmware/board data version
e.g hw mode 9, then it will also lead new array overflow without this
change.

for mlo_capable
Currently, the encoding rule for field mlo_capable in struct
qmi_wlanfw_host_cap_req_msg_v01 defined in array
qmi_wlanfw_host_cap_req_msg_v01_ei uses type QMI_OPT_FLAG.
Unfortunately, all ath12k firmware actually expects this field to be of
type NON QMI_OPT_FLAG such as QMI_UNSIGNED_1_BYTE/QMI_UNSIGNED_8_BYTE...
And as a result, firmware is unable to correctly decode the mlo_capable
field.
Change the ath12k definition as QMI_UNSIGNED_1_BYTE to match the firmware
definition so that firmware can correctly parse the mlo_capable info from
message QMI_WLANFW_HOST_CAP_REQ_V01 at wlan load time.
This is just an accidental typo and that both WCN7850 and QCN9274 firmwares
use QMI_UNSIGNED_1_BYTE.

In some race conditions, calibration done QMI message is received even
before host wait starts for calibration to be done.
Due to this, resetting firmware was not performed after calibration.
Hence, remove cal_done check in ath11k_qmi_fwreset_from_cold_boot()
as this is called only from probe.

QCN9074 supports 6 GHz, which has increased number of channels
compared to 5 GHz/2 GHz. So, to support coldboot calibration in
QCN9074 ATH11K_COLD_BOOT_FW_RESET_DELAY extended to 60 seconds. To
avoid code redundancy, fwreset_from_cold_boot moved to QMI and made
common for both ahb and pci. Coldboot calibration is enabled only in
FTM mode for QCN9074. QCN9074 requires firmware restart after coldboot,
hence enable cbcal_restart_fw in hw_params.
This support can be enabled/disabled using hw params for different
hardware. Currently it is not enabled for QCA6390.

5 GHz band channel 177 support was added with the commit e5e94d10c856 ("wifi:
ath11k: add channel 177 into 5 GHz channel list"). However, during processing
for the received ppdu in ath11k_dp_rx_h_ppdu(), channel number is checked only
till 173. This leads to driver code checking for channel and then fetching the
band from it which is extra effort since firmware has already given the channel
number in the metadata.
Fix this issue by checking the channel number till 177 since we support
it now.
Found via code review. Compile tested only.

Using brcmfmac with 6.5-rc3 on a brcmfmac43241b4-sdio triggers
a backtrace caused by the following field-spanning warning:
memcpy: detected field-spanning write (size 120) of single field
"¶ms_le->channel_list[0]" at
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:1072 (size 2)
The driver still works after this warning. The warning was introduced by the
new field-spanning write checks which were enabled recently.
Fix this by replacing the channel_list[1] declaration at the end of
the struct with a flexible array declaration.
Most users of struct brcmf_scan_params_le calculate the size to alloc
using the size of the non flex-array part of the struct + needed extra
space, so they do not care about sizeof(struct brcmf_scan_params_le).
brcmf_notify_escan_complete() however uses the struct on the stack,
expecting there to be room for at least 1 entry in the channel-list
to store the special -1 abort channel-id.
To make this work use an anonymous union with a padding member
added + the actual channel_list flexible array.

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
Direct replacement is safe here since DEV_ASSIGN is only used by
TRACE macros and the return values are ignored.
