ath9k_htc_txstatus()
Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug
occurs when txs->cnt, data from a URB provided by a USB device, is
bigger than the size of the array txs->txstatus, which is
HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug
handling code after the check. Make the function return if that is the
case.
Found by a modified version of syzkaller.
UBSAN: array-index-out-of-bounds in htc_drv_txrx.c

Currently data path Rxdma ring structure store the IDR buffer and lock.
These IDR handling is needed only for SW cookie conversion and not
needed for HW cookie conversion. REO Rxdma ring use the HW cookie
conversion and monitor Rxdma ring use the SW cookie conversion.
Since idr not needed for REO Rxdma ring, remove the IDR data entity
from the data path Rxdma ring structure. Introduce the new data path ring
structure for monitor rxmda rings since it need IDR data entity.

Currently Rxdma replenish require HW conversion argument which is
unnecessary argument since ath12k driver configures the Rxdma only
in HW conversion. To optimize the rx data path per packet, avoid
the explicit unnecessary argument and condition check in the rx

When the core rfkill config throws error, it should free the
allocated resources. Currently it is not freeing the core pdev
create resources. Avoid this issue by calling the core pdev
destroy in the error handler of core rfkill config.

Let ath12k select this option automatically which makes building

Currently wmi.h has two separate set of definitions for peer
flags. One set of flags is defined in enum wmi_tlv_peer_flags, and,
except for the last three, are named WMI_TLV_PEER_*. The other set of
flags are defined as macros, and are named WMI_PEER_*. The last three
macros have the same name as the last three wmi_tlv_peer_flags
enumerators.
The code only uses the WMI_PEER_* names; the WMI_TLV_PEER_* names are
unused. So as a first step in consolidation, remove all the
WMI_TLV_PEER_* names.
But since having an enum to define all the flags is actually a good
thing since that provides a handle by which to refer to the entire set
of flags, recast the WMI_PEER_* macros into enumerators.
Compile tested only.

If we already have gotten the rproc_handle (meaning the "qcom,rproc"
property is defined in the devicetree), it's a valid state that the
remoteproc module hasn't probed yet so we should defer probing instead
of just failing to probe.
This resolves a race condition when the ath11k driver probes and fails
before the wpss remoteproc driver has probed, like the following:
[ 6.232360] ath11k 17a10040.wifi: failed to get rproc
[ 6.232366] ath11k 17a10040.wifi: failed to get rproc: -22
[ 6.232478] ath11k: probe of 17a10040.wifi failed with error -22
...
[ 6.252415] remoteproc remoteproc2: 8a00000.remoteproc is available
[ 6.252776] remoteproc remoteproc2: powering up 8a00000.remoteproc
[ 6.252781] remoteproc remoteproc2: Booting fw image qcom/qcm6490/fairphone5/wpss.mdt, size 7188
So, defer the probe if we hit that so we can retry later once the wpss
remoteproc is available.

strncpy() is deprecated [1] and we should prefer less ambiguous
interfaces.
In this case, arvif->u.ap.ssid has its length maintained by
arvif->u.ap.ssid_len which indicates it may not need to be
NUL-terminated. Make this explicit with __nonstring and use a plain old
memcpy.
This is also consistent with future copies into arvif->u.ap.ssid:
if (changed & BSS_CHANGED_SSID &&
vif->type == NL80211_IFTYPE_AP) {
arvif->u.ap.ssid_len = vif->cfg.ssid_len;
if (vif->cfg.ssid_len)
memcpy(arvif->u.ap.ssid, vif->cfg.ssid,
vif->cfg.ssid_len);
arvif->u.ap.hidden_ssid = info->hidden_ssid;
}

Currently, the logic to return an ath12k_sta pointer, given a
ieee80211_sta pointer, uses typecasting throughout the driver. In
general, conversion functions are preferable to typecasting since
using a conversion function allows the compiler to validate the types
of both the input and output parameters.
ath12k already defines a conversion function ath12k_vif_to_arvif() for
a similar conversion. So introduce ath12k_sta_to_arsta() for this use
case, and convert all of the existing typecasting to use this
function.

In PCI and HAL interface layer module, the identifier sc is used
to represent an instance of ath12k_base structure. However,
within ath12k, the convention is to use "ab" to represent an SoC
"base" struct. So change the all instances of sc to ab.

Firmware IE containers can dynamically provide various information
what firmware supports. Also it can embed more than one image so
updating firmware is easy, user just needs to update one file in
/lib/firmware/.
The firmware API 2 or higher will use the IE container format, the
current API 1 will not use the new format but it still is supported
for some time. Firmware API 2 files are named as firmware-2.bin
(which contains both amss.bin and m3.bin images) and API 1 files are
amss.bin and m3.bin.
Currently ath11k PCI driver provides firmware binary (amss.bin) path to
MHI driver, MHI driver reads firmware from filesystem and boots it. Add
provision to read firmware files from ath11k driver and provide the amss.bin
firmware data and size to MHI using a pointer.
Currently enum ath11k_fw_features is empty, the patches adding features will
add the flags.
With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB
firmware files are used. But AHB devices can use future additions to the meta
data, for example in enum ath11k_fw_features.

Simple refactoring to make it easier to add firmware-2.bin support in the
following patch.
Earlier ath11k_qmi_m3_load() supported changing m3.bin contents while ath11k is
running. But that's not going to actually work, m3.bin is supposed to be the
same during the lifetime of ath11k, for example we don't support changing the
firmware capabilities on the fly. Due to this ath11k requests m3.bin firmware
file first and only then checks m3_mem->vaddr, so we are basically requesting
the firmware file even if it's not needed. Reverse the code so that m3_mem
buffer is checked first, and only if it doesn't exist, then m3.bin is requested
from user space.
Checking for m3_mem->size is redundant when m3_mem->vaddr is NULL, we would
not be able to use the buffer in that case. So remove the check for size.
Simplify the exit handling and use 'goto out'.

When compiling with clang-18, I've noticed the following:
drivers/net/wireless/realtek/rtw89/fw.c:389:28: warning: cast to smaller
integer type 'enum rtw89_fw_type' from 'const void *' [-Wvoid-pointer-to-enum-cast]

569 | rf_path = (enum rtw89_rf_path)data;

So avoid brutal everything-to-const-void-and-back casts, introduce
'union rtw89_fw_element_arg' to pass parameters to element handler
callbacks, and adjust all of the related bits accordingly. Compile
tested only.

1. Do not hard reset the BBP. We can use soft reset instead. This
change has some help to the calibration failure issue.
2. Enable falling back to legacy rate from the HT/RTS rate by
setting the HT_FBK_TO_LEGACY register.
3. Implement MCS rate specific maximum PSDU size. It can improve
the transmission quality under the low RSSI condition.
4. Set BBP_84 register value to 0x19. This is used for extension

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect fw_version strings to be NUL-terminated based on other similar

wireless/intel/ipw2x00/ipw2100.c
5905: snprintf(info->fw_version, sizeof(info->fw_version), "%s:%d:%s",
Based on this, NUL-padding is not required.
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.

wl->chip.phy_fw_ver_str is obviously intended to be NUL-terminated by
the deliberate comment telling us as much. Furthermore, its only use is
drivers/net/wireless/ti/wlcore/debugfs.c shows us it should be
NUL-terminated since its used in scnprintf:
492 | DRIVER_STATE_PRINT_STR(chip.phy_fw_ver_str);
which is defined as:
| #define DRIVER_STATE_PRINT_STR(x) DRIVER_STATE_PRINT(x, "%s")

We can also see that NUL-padding is not required.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer

The very fact that a plain-english comment had to be made alongside a
manual NUL-byte assignment for such a simple purpose shows why strncpy
is faulty. It has non-obvious behavior that has to be clarified every
time it is used (and if it isn't then the reader suffers).

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
`extra` is intended to be NUL-terminated which is evident by the manual
assignment of a NUL-byte as well as its immediate usage with strlen().
Moreover, many of these getters and setters are NUL-padding buffers with
memset():
2439 | memset(&tx_power, 0, sizeof(tx_power));
9998 | memset(sys_config, 0, sizeof(struct ipw_sys_config));
10084 | memset(tfd, 0, sizeof(*tfd));
10261 | memset(&dummystats, 0, sizeof(dummystats));
... let's maintain this behavior and NUL-pad our destination buffer.
Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees both NUL-termination and NUL-padding on the
destination buffer.
To be clear, there is no bug in the current implementation as
MAX_WX_STRING is much larger than the size of the string literals being
copied from. Also, strncpy() does NUL-pad the destination buffer and
using strscpy_pad() simply matches that behavior. All in all, there
should be no functional change but we are one step closer to eliminating
usage of strncpy().
Do note that we cannot use the more idiomatic strscpy invocation of
(dest, src, sizeof(dest)) as the destination buffer cannot have its size
determined at compile time. So, let's stick with (dest, src, LEN).

The watchdog function is broken on rt2800 series SoCs. This patch
fixes the incorrect watchdog logic to make it work again.
1. Update current wdt queue index if it's not equal to the previous
index. Watchdog compares the current and previous queue index to
judge if the queue hung.
2. Make sure hung_{rx,tx} 'true' status won't be override by the
normal queue. Any queue hangs should trigger a reset action.
3. Clear the watchdog counter of all queues before resetting the
hardware. This change may help to avoid the reset loop.
4. Change hang check function return type to bool as we only need
to return two status, yes or no.

On v6.6-rc4 with GCC 13.2 I see:
drivers/net/wireless/ath/ath9k/hif_usb.c:1223:42: warning: '.0.fw' directive output may be truncated writing 5 bytes into a region of size between 4 and 11 [-Wformat-truncation=]
drivers/net/wireless/ath/ath9k/hif_usb.c:1222:17: note: 'snprintf' output between 27 and 34 bytes into a destination of size 32
Fix it by increasing the size of the fw_name field to 64 bytes.
Compile tested only.

Fix this by copying only the firmware version and not providing any extra
information via ethtool. This is an ancient driver anyway and most likely
removed soon so it doesn't really matter.
Compile tested only.
