ec2e93cf19 b43: Avoid possible double calls to b43_one_core_detach()
In b43_request_firmware(), when ieee80211_register_hw() fails,
b43_one_core_detach() is called. In b43_bcma_remove() and
b43_ssb_remove(), b43_one_core_detach() is called again. In this case,
null-pointer dereferences and double-free problems can occur when
the driver is removed.

To fix this bug, the call to b43_one_core_detach() in
b43_request_firmware() is deleted.

This bug is found by a runtime fuzzing tool named FIZZER written by us.

f7fbb03f21 rtlwifi: rtl8821ae: Convert inline routines to little-endian words
In this step, the read/write routines for the descriptors are converted
to use __le32 quantities, thus a lot of casts can be removed. Callback
routines still use the 8-bit arrays, but these are changed within the
specified routine.

The macro that cleared a descriptor has now been converted into an inline
routine.

bd421dab75 rtlwifi: rtl8821ae: Convert macros that set descriptor
As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed later.

f5678bfe1c rtlwifi: rtl8821ae: Replace local bit manipulation macros
This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

0e7d38132b rtlwifi: 8192de: Fix used uninitialized variables in power tracking
ofdm_index_old[] is the index of ofdmswing_table[], and used to indicate
initial value of ROFDM0_X{A,B}TXIQIMBALANCE in rtl8192de_phy_reg_2tarray[]
table, and the initial value is corresponding to calibration thermal value
written in efuse, namely rtlefuse->eeprom_thermalmeter. Then, local
variable ofdm_index_old[] save to rtlpriv->dm.ofdm_index[] for operational
use.

If thermal value (temperature) is increasing, output TX power is lower.
So, we calculate the delta between current and calibration thermal value,
then add power to yield expected and the same output TX power.

Thus, ofdm_index[] should be initialized as rtlpriv->dm.ofdm_index[], and
shift to proper index depends on delta of thermal value. Then, new power
value ofdmswing_table[ofdm_index[]] is written to register.

c11c75ec78 p54: Support boottime in scan results
This patch fixes an issue with wpa_supplicant dropping all scan
results because their where considered to be "too old" (e.g.:
"skip - scan result not recent enough (121056.086325 seconds too old)")
which is very weird because this looks like that the scan results have
been received before a scan started. This is due to the inaccuracy of
the default timing mechanism for calculating the BSS entry age.

1645ab9319 p54: fix crash during initialization
This patch fixes a crash that got introduced when the
mentioned patch replaced  the direct list_head access
with skb_peek_tail(). When the device is starting up,
there are  no entries in  the queue, so previously to
"Use skb_peek_tail() instead..." the target_skb would
end up as the  tail and head pointer which then could
be used by __skb_queue_after to fill the empty queue.

With skb_peek_tail() in its place will instead just
return NULL which then causes a crash in the
__skb_queue_after().

Using Clang's suggestion of initializing data to NULL wouldn't work out
because data will be dereferenced by put_unaligned_le32. Use kzalloc to
properly initialize data, which matches a couple of other places in this
driver.

a24bad7473 rtw88: fix unassigned rssi_level in rtw_sta_info
The new rssi_level should be stored in si, otherwise the rssi_level will
never be updated and get a wrong RA mask, which is calculated by the
rssi level

If a wrong RA mask is chosen, the firmware will pick some *bad rates*.
The most hurtful scene will be in *noisy environment*, such as office or
public area with many APs and users.
The latency would be high and the overall throughput would be only half
or less.

Tested in 2.4G in office area, with this patch the throughput increased
from such as "1x Mbps -> 4x Mbps".

1b9705d971 net: wireless: mt76: fix similar warning reported by kbuild test robot
This patch fixes following (similar) warning reported by kbuild test robot:

 In function ‘memcpy’,
  inlined from ‘smsc75xx_init_mac_address’ at drivers/net/usb/smsc75xx.c:778:3,
  inlined from ‘smsc75xx_bind’ at drivers/net/usb/smsc75xx.c:1501:2:
  ./include/linux/string.h:355:9: warning: argument 2 null where non-null expected [-Wnonnull]
  return __builtin_memcpy(p, q, size);

  drivers/net/usb/smsc75xx.c: In function ‘smsc75xx_bind’:
  ./include/linux/string.h:355:9: note: in a call to built-in function ‘__builtin_memcpy’

I've replaced the offending memcpy with ether_addr_copy, because I'm
100% sure, that of_get_mac_address can't return NULL as it returns valid
pointer or ERR_PTR encoded value, nothing else.

I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this
would make the warning disappear also, but it would be confusing to
check for impossible return value just to make a compiler happy.

I'm now changing all occurencies of memcpy to ether_addr_copy after the
of_get_mac_address call, as it's very likely, that we're going to get
similar reports from kbuild test robot in the future.

49ed34b835 ath10k: add peer id check in ath10k_peer_find_by_id
For some SDIO chip, the peer id is 65535 for MPDU with error status,
then test_bit will trigger buffer overflow for peer's memory, if kasan
enabled, it will report error.

Reason is when station is in disconnecting status, firmware do not delete
the peer info since it not disconnected completely, meanwhile some AP will
still send data packet to station, then hardware will receive the packet
and send to firmware, firmware's logic will report peer id of 65535 for
MPDU with error status.

Add check for overflow the size of peer's peer_ids will avoid the buffer
overflow access.

7835d8f879 ath10k: Add wmi tlv service map for mesh 11s
WCN3990 firmware advertises the service WMI_TLV_SERVICE_MESH_11S
for mesh 11s. Map this wmi tlv service to enable mesh 11s
for WCN3990.

97354f2c43 ath10k: Do not send probe response template for mesh
Currently mac80211 do not support probe response template for
mesh point. When WMI_SERVICE_BEACON_OFFLOAD is enabled, host
driver tries to configure probe response template for mesh, but
it fails because the interface type is not NL80211_IFTYPE_AP but
NL80211_IFTYPE_MESH_POINT.

To avoid this failure, skip sending probe response template to
firmware for mesh point.

There is a disparity in wmi and wmi tlv vdev subtype
enum for WMI_VDEV_SUBTYPE_MESH_11S.

Add different enum for wmi tlv vdev subtype to support
vdev of subtype mesh 11s for WCN3990.

8cdee1affe ath10k: change swap mail box config for UTF mode of SDIO
For SDIO chip, it does not have HTT connect step in boot phase of UTF
mode, so it does not need the swap configuration for UTF mode, otherwise
it will trigger UTF load fail. For normal mode, it is swap between HTT
and WMI, for UTF mode, it does not have HTT, so it can not swap between
HTT and WMI.

Disable swap mail box for UTF mode will let UTF mode load success.

9280f4fc06 ath10k: Fix the wrong value of enums for wmi tlv stats id
The enum value for WMI_TLV_STAT_PDEV, WMI_TLV_STAT_VDEV
and WMI_TLV_STAT_PEER is wrong, due to which the vdev stats
are not received from firmware in wmi_update_stats event.

Fix the enum values for above stats to receive all stats
from firmware in WMI_TLV_UPDATE_STATS_EVENTID.

4f735cd736 ath10k: coredump: use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace code of the following form:

sizeof(*ce_hdr) + CE_COUNT * sizeof(ce_hdr->entries[0])

with:

struct_size(ce_hdr, entries, CE_COUNT)

This code was detected with the help of Coccinelle.
