f937275364 mt76: mt7915: set VTA bit in tx descriptor
The VTA (Valid for Txd Arrival time) bit should be set in tx descriptor,
which is necessary for WM fw to schedule SPL (station priority list)
normally before generating txcmd.
If it's not set, some unexpected wcids may be involved in SPL.

a1b0bbd484 mt76: use a separate CCMP PN receive counter for management frames
When received frame is decryped by hardware, CCMP PN is checked by
mt76.

When management frame protection (IEEE 802.11w) is used, we must use
a separate counter for tracking received CCMP packet number for the
management frames. The previously used counter was shared with data
frames and that can cause problems in detecting replays incorrectly
for robust management frames.

Add a new counter just for robust management frames to avoid this
issue.

a90f2115c1 mt76: mt7915: add more MIB registers
Add register definitions and read & accumulate them in
the mib polling logic.  Note that some registers should not
be read since firmware is already reading them.  If driver
reads those, they will be cleared-on-read, and so the firmware
stats will be incorrect.

For these 'do-not-read' stats, add them to the registers definition
so that other developers can be aware of these constraints, but do
not actually read them in the driver.

Update the proper firmware programming sequence to fix GTK rekey
offload failure on WPA mixed mode.

In the mt76_connac_mcu_key_iter,
gtk_tlv->proto should be only set up on pairwise key
and gtk_tlk->group_cipher should be only set up on the group key.

Otherwise, those parameters required by firmware would be set
incorrectly to cause GTK rekey offload failure on WPA mixed mode
and then disconnection follows.

The 0-element arrays that are used as memcpy() destinations are actually
flexible arrays. Adjust their structures accordingly so that memcpy()
can better reason able their destination size (i.e. they need to be seen
as "unknown" length rather than "zero").

In some cases, use of the DECLARE_FLEX_ARRAY() helper is needed when a
flexible array is alone in a struct.

8e3e59c31f mwifiex: Try waking the firmware until we get an interrupt
It seems that the PCIe+USB firmware (latest version 15.68.19.p21) of the
88W8897 card sometimes ignores or misses when we try to wake it up by
writing to the firmware status register. This leads to the firmware
wakeup timeout expiring and the driver resetting the card because we
assume the firmware has hung up or crashed.

Turns out that the firmware actually didn't hang up, but simply "missed"
our wakeup request and didn't send us an interrupt with an AWAKE event.

Trying again to read the firmware status register after a short timeout
usually makes the firmware wake up as expected, so add a small retry
loop to mwifiex_pm_wakeup_card() that looks at the interrupt status to
check whether the card woke up.

The number of tries and timeout lengths for this were determined
experimentally: The firmware usually takes about 500 us to wake up
after we attempt to read the status register. In some cases where the
firmware is very busy (for example while doing a bluetooth scan) it
might even miss our requests for multiple milliseconds, which is why
after 15 tries the waiting time gets increased to 10 ms. The maximum
number of tries it took to wake the firmware when testing this was
around 20, so a maximum number of 50 tries should give us plenty of
safety margin.

Here's a reproducer for those firmware wakeup failures I've found:

1) Make sure wifi powersaving is enabled (iw dev wlp1s0 set power_save on)
2) Connect to any wifi network (makes firmware go into wifi powersaving
mode, not deep sleep)
3) Make sure bluetooth is turned off (to ensure the firmware actually
enters powersave mode and doesn't keep the radio active doing bluetooth
stuff)
4) To confirm that wifi powersaving is entered ping a device on the LAN,
pings should be a few ms higher than without powersaving
5) Run "while true; do iwconfig; sleep 0.0001; done", this wakes and
suspends the firmware extremely often
6) Wait until things explode, for me it consistently takes <5 minutes

e5f4eb8223 mwifiex: Read a PCI register after writing the TX ring write pointer
On the 88W8897 PCIe+USB card the firmware randomly crashes after setting
the TX ring write pointer. The issue is present in the latest firmware
version 15.68.19.p21 of the PCIe+USB card.

Those firmware crashes can be worked around by reading any PCI register
of the card after setting that register, so read the PCI_VENDOR_ID
register here. The reason this works is probably because we keep the bus
from entering an ASPM state for a bit longer, because that's what causes
the cards firmware to crash.

This fixes a bug where during RX/TX traffic and with ASPM L1 substates
enabled (the specific substates where the issue happens appear to be
platform dependent), the firmware crashes and eventually a command
timeout appears in the logs.

rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges
are totally redefined, so it's impossible to reuse register definition. To
communicate with firmware, new H2C/C2H format is proposed. In order to have
better utilization, TX DMA flow is changed to two stages DMA. To provide
rich RX status information, additional RX PPDU packets are added.

Since there are so many differences mentioned above, we decide to propose
a new driver. It has many authors, they are listed in alphabetic order:

0a491167fe ath10k: fix max antenna gain unit
Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
steps). This isn't the case for max_antenna_gain - which is still expected
by the firmware as dB.

The firmware is converting it from dB to the internal (twicepower)
representation when it calculates the limits of a channel. This can be seen
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).

Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

8cd5c08471 ath11k: Identify DFS channel when sending scan channel list command
WMI_CHAN_INFO_DFS flag should be set when configuring a DFS channel
included in scan channel list. Without it, firmware will not send a
probe request frame which is needed in connection to an AP configured
with hidden SSID/network_id. So fix this to allow probe request frames
to be sent in cases where a beacon frame has been seen on the channel
first.

03469e79fe ath9k: support DT ieee80211-freq-limit property to limit channels
The common DT property can be used to limit the available channels
but ath9k has to manually call wiphy_read_of_freq_limits().

I would have put this into ath9k_of_init(). But it didn't work there.
The reason is that in ath9k_of_init() the channels and bands are not yet
registered in the wiphy struct. So there isn't any channel to flag as
disabled.

96527d527b ath11k: Handle MSI enablement during rmmod and SSR
When doing "rmmod ath11k_pci", ath11k performs global SOC reset
and MHI reset, where 0 address access is captured by IOMMU. See
log below:

...
[  133.953860] ath11k_pci 0000:02:00.0: setting mhi state: DEINIT(1)
[  133.959714] ath11k_pci 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020]
[  133.973854] ath11k_pci 0000:02:00.0: MHISTATUS 0xff04

...

This issue is also observed in SSR process, cause a similar
sequence as above is performed.

Such an invalid access occurs because, during rmmod or SSR, MSI
address is cleared but HW MSI functionality not disabled, thus HW
target is able to raise an MSI transaction with 0 as MSI address.

So it can be fixed by simply disabling MSI before reset. For SSR,
since MSI functionality is still needed after target is brought
back, we need to reenable it.

Also change naming of some interfaces related.

kzalloc() is used to allocate memory for cd->detectors, and if it fails,
channel_detector_exit() behind the label fail will be called:

0dcf60d001 asm-generic: build fixes for v5.15
There is one build fix for Arm platforms that ended up impacting most
 architectures because of the way the drivers/firmware Kconfig file is
 wired up:
 
 The CONFIG_QCOM_SCM dependency have caused a number of randconfig
 regressions over time, and some still remain in v5.15-rc4. The
 fix we agreed on in the end is to make this symbol selected by any
 driver using it, and then building it even for non-Arm platforms with
 CONFIG_COMPILE_TEST.
 
 To make this work on all architectures, the drivers/firmware/Kconfig
 file needs to be included for all architectures to make the symbol
 itself visible.
 
 In a separate discussion, we found that a sound driver patch that is
 pending for v5.16 needs the same change to include this Kconfig file,
 so the easiest solution seems to have my Kconfig rework included in v5.15.
 
 There is a small merge conflict against an earlier partial fix for the
 QCOM_SCM dependency problems.
 
 Finally, the branch also includes a small unrelated build fix for NOMMU
 architectures.

424953cf3c qcom_scm: hide Kconfig symbol
Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:

aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'

ld.lld: error: undefined symbol: qcom_scm_is_available
>>> referenced by adreno_gpu.c
>>>               gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a

This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.

This appears to be an endless problem, so try something different this
time:

 - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
   but that is simply selected by all of its users

 - All the stubs in include/linux/qcom_scm.h can go away

 - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
   allow compile-testing QCOM_SCM on all architectures.

 - To avoid a circular dependency chain involving RESET_CONTROLLER
   and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
   According to my testing this still builds fine, and the QCOM
   platform selects this symbol already.

4925642d54 ath9k: Fix potential interrupt storm on queue reset
In tests with two Lima boards from 8devices (QCA4531 based) on OpenWrt
19.07 we could force a silent restart of a device with no serial
output when we were sending a high amount of UDP traffic (iperf3 at 80
MBit/s in both directions from external hosts, saturating the wifi and
causing a load of about 4.5 to 6) and were then triggering an
ath9k_queue_reset().

Further debugging showed that the restart was caused by the ath79
watchdog. With disabled watchdog we could observe that the device was
constantly going into ath_isr() interrupt handler and was returning
early after the ATH_OP_HW_RESET flag test, without clearing any
interrupts. Even though ath9k_queue_reset() calls
ath9k_hw_kill_interrupts().

With JTAG we could observe the following race condition:

1) ath9k_queue_reset()
   ...
   -> ath9k_hw_kill_interrupts()
   -> set_bit(ATH_OP_HW_RESET, &common->op_flags);
   ...
   <- returns

      2) ath9k_tasklet()
         ...
         -> ath9k_hw_resume_interrupts()
         ...
         <- returns

                 3) loops around:
                    ...
                    handle_int()
                    -> ath_isr()
                       ...
                       -> if (test_bit(ATH_OP_HW_RESET,
                                       &common->op_flags))
                            return IRQ_HANDLED;

                    x) ath_reset_internal():
                       => never reached <=

And in ath_isr() we would typically see the following interrupts /
interrupt causes:

* status: 0x00111030 or 0x00110030
* async_cause: 2 (AR_INTR_MAC_IPQ)
* sync_cause: 0

So the ath9k_tasklet() reenables the ath9k interrupts
through ath9k_hw_resume_interrupts() which ath9k_queue_reset() had just
disabled. And ath_isr() then keeps firing because it returns IRQ_HANDLED
without actually clearing the interrupt.

To fix this IRQ storm also clear/disable the interrupts again when we
are in reset state.

053f9852b9 ath9k: add option to reset the wifi chip via debugfs
Sometimes, in yet unknown cases the wifi chip stops working. To allow a
watchdog in userspace to easily and quickly reset the wifi chip, add the
according functionality to userspace. A reset can then be triggered
via:

  $ echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/reset

The number of user resets can further be tracked in the row "User reset"
in the same file.

So far people usually used "iw scan" to fix ath9k chip hangs from
userspace. Which triggers the ath9k_queue_reset(), too. The reset file
however has the advantage of less overhead, which makes debugging bugs
within ath9k_queue_reset() easier.

747ff7d3d7 ath10k: Don't always treat modem stop events as crashes
When rebooting on sc7180 Trogdor devices I see the following crash from
the wifi driver.

 ath10k_snoc 18800000.wifi: firmware crashed! (guid 83493570-29a2-4e98-a83e-70048c47669c)

This is because a modem stop event looks just like a firmware crash to
the driver, the qmi connection is closed in both cases. Use the qcom ssr
notifier block to stop treating the qmi connection close event as a
firmware crash signal when the modem hasn't actually crashed. See
ath10k_qmi_event_server_exit() for more details.

This silences the crash message seen during every reboot.

7acd723c30 rtl8xxxu: Use lower tx rates for the ack packet
According to the Realtek propritary driver and the rtw88 driver, the
tx rates of the ack (includes block ack) are initialized with lower
tx rates (no HT rates) which is set by the RRSR register value. In
real cases, ack rate higher than current tx rate could lead to
difficulty for the receiving end to receive management/control frames.
The retransmission rate would be higher then expected when the driver
is acting as receiver and the RSSI is not good.

Cross out higer rates for ack packet before implementing dynamic rrsr
configuration like the commit 4830872685 ("rtw88: add dynamic rrsr
configuration").

6cd4b59ddb rtw88: refine fw_crash debugfs to show non-zero while triggering
The usage of fw_crash debugfs is to write 1 to it to trigger fw crash
simulation and to read from it to check the state. When zero is read,
it is supposed to mean fw crash/restart process is done. Then, some
test plans can be designed for crash/restart.
e.g.
step 1. trigger fw crash simulation
step 2. poll the state until zero is read
step 3. check connection by ping test

However, in certain connection cases, triggering fw crash simulation
will take a while. If the state is queried too early before restart
begins processing, it may mistakenly think restart process has been
done. If some tests are started at this time, something unexpected
might happen due to the follow-up restart process.

To avoid that, let fw_crash also show non-zero when a simulation
is still triggering.

add missing BH locking around napi_schdule()").

Its commit log provides the following explanation:

"It's not correct to call napi_schedule() in pure process
context. Because we use __raise_softirq_irqoff() we require
callers to be in a context which will eventually lead to
softirq handling (hardirq, bh disabled, etc.).

With code as is users will see:

86a03dad0f ath11k: Change DMA_FROM_DEVICE to DMA_TO_DEVICE when map reinjected packets
For fragmented packets, ath11k reassembles each fragment as a normal
packet and then reinjects it into HW ring. In this case, the DMA
direction should be DMA_TO_DEVICE, not DMA_FROM_DEVICE, otherwise
invalid payload will be reinjected to HW and then delivered to host.
What is more, since arbitrary memory could be allocated to the frame, we
don't know what kind of data is contained in the buffer reinjected.
Thus, as a bad result, private info may be leaked.

Note that this issue is only found on Intel platform.

62db14ea95 ath11k: indicate to mac80211 scan complete with aborted flag for ATH11K_SCAN_STARTING state
Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo assert > /sys/kernel/debug/ath11k/qca6490\ hw2.0/simulate_fw_crash
   immediately after step 1.

result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)

reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath11k_mac_op_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath11k_mac_scan_finish() which is called from
ath11k_core_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH11K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.

Indicate scan complete with aborted flag to mac80211 for
ATH11K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.

c677d4b1bc ath11k: indicate scan complete for scan canceled when scan running
ath11k prints "Received scan event for unknown vdev" when doing the
following test:
1. trigger scan
2. wait 0.2 second
3. iw reg set or 11d scan complete from firmware

Reason: When iw reg set or 11d scan complete, the new country code will
be set to the firmware, and the new regdomain info indicated to ath11k,
then the new channel list will be sent to the firmware. The firmware
will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID
which is used for the new channel list, and the state of ath11k is
ATH11K_SCAN_RUNNING, then ath11k_get_ar_on_scan_abort() returns NULL and
ath11k_scan_event() returns at this point and does not indicate scan
completion to mac80211.

Indicate scan completion to mac80211 and get rid of the "Received scan
event for unknown vdev" print for the above case.

441b3b5911 ath11k: add handler for scan event WMI_SCAN_EVENT_DEQUEUED
When wlan interface is up, 11d scan is sent to the firmware, and the
firmware needs to spend couple of seconds to complete the 11d scan. If
immediately a normal scan from user space arrives to ath11k, then the
normal scan request is also sent to the firmware, but the scan started
event will be reported to ath11k until the 11d scan complete. When timed
out for the scan started in ath11k, ath11k stops the normal scan and the
firmware reports WMI_SCAN_EVENT_DEQUEUED to ath11k for the normal scan.
ath11k has no handler for the event and then timed out for the scan
completed in ath11k_scan_stop(), and ath11k prints the following error
message.

[ 1491.604750] ath11k_pci 0000:02:00.0: failed to receive scan abort comple: timed out
[ 1491.604756] ath11k_pci 0000:02:00.0: failed to stop scan: -110
[ 1491.604758] ath11k_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.

74327bab67 ath11k: Remove htt stats fixed size array usage
To support the HTT Stats DebugFS interface a single large buffer that
contains the stats must be provided to the DebugFS infrastructure.
In the current code, for each class of stats, the stats are first
formatted in a local on-stack buffer, and then the local buffer is
copied to the large DebugFS buffer.

This logic has a problem when, for a given class, the formatted
stats exceed the size of the on-stack buffer. When this occurs the
stats for this class is truncated. In addition, this logic is
inefficient since it introduces an unnecessary memory copy.

To address these issues, update the logic to no longer use a local
on-stack buffer, and instead write the formatted data directly into
the large DebugFS buffer.

8a0b899f16 ath11k: Fix inaccessible debug registers
Current code clears debug registers after SOC global reset performed
in ath11k_pci_sw_reset. However at that time those registers are
not accessible due to reset, thus they are actually not cleared at all.
For WCN6855, it may cause target fail to initialize. This issue can be
fixed by moving clear action ahead.

In addition, on some specific platforms, need to add delay to wait
those registers to become accessible.

74bba5e5ba ath11k: enable 6G channels for WCN6855
For some chips such as WCN6855, single_pdev_only is set in struct
ath11k_hw_params which means ath11k calls ieee80211_register_hw() only
once and create only one device interface, and that device interface
supports all 2G/5G/6G channels.

ath11k_mac_setup_channels_rates() sets up the channels and it is called
for each device interface. It is called only once for single_pdev_only,
and then set up all channels for 2G/5G/6G. The logic of
ath11k_mac_setup_channels_rates() is not suitable for single_pdev_only,
it leads to all 6G channels being disabled for the device interface
which is single_pdev_only such as WCN6855.

Add channel frequency checks for the 6G band and enable the 6G channels
properly based on what is supported by the chip.

ath11k_mac_get_arvif() throws a warning message if the given vdev_id is

8ee8d38ca4 ath11k: Fix crash during firmware recovery on reo cmd ring access
In scenario when a peer is disassociating, there could be
multiple places where a reo cmd ring is accessed, such as
during aggregation teardown, tid queue cleanup, etc.

When this happens during firmware recovery where accessing of FW/HW
resources/registers is not recommended, accessing reo cmd ring in
this case could lead to crash or undefined behaviour.

Hence avoid this by checking for corresponding flag to avoid
accessing reo cmd ring during firmware recovery.

in vdev_create command. This is due to free_vdev_map value being 0.
free_vdev_map is getting assigned after ieee80211_register_hw. In
some race conditions, add_interface api is getting called before
assigning value to free_vdev_map. Fix this by assigning free_vdev_map
before ieee80211_register_hw.

Also, moved ar->cc_freq_hz and ar->txmgmt_idr initialization before
ieee80211_register_hw to avoid such race conditions.

8717db7ee8 ath11k: Add vdev start flag to disable hardware encryption
Firmware blocks all data traffic until the key is plumbed. But, with
software encryption mode, key is never plumbed to firmware. Due to this,
a traffic failure in software encryption mode has been observed. Hence,
firmware has introduced a flag to differentiate software encryption
mode. This flag can be passed during vdev_start command.

Enable WMI_VDEV_START_HW_ENCRYPTION_DISABLED flag in vdev_start command
to notify firmware to disable hardware encryption for a vdev. This is set
if raw mode software encryption is enabled.

1db2b0d0a3 ath11k: Avoid race during regd updates
Whenever ath11k is bootup with a user country already set, cfg80211
notifies this country info to ath11k soon after registration, where the
notification is sent to the firmware for fetching the rules of this user
country input.

Multiple race conditions could be seen in this scenario where a new
request is either lost as pointed in [1] or a new regd overwrites the
default regd provided by the firmware during bootup. Note that, the
default regd is used for intersection purpose and hence it should not be
overwritten.

The main reason as pointed by [1] is the usage of ATH11K_FLAG_REGISTERED
flag which is updated after completion of core registration, whereas the
reg notification from cfg80211 and wmi events for the corresponding
request can happen much before that. Since the ATH11K_FLAG_REGISTERED is
currently used to determine if the event containing reg rules belong to
default regd or for user request, there is a possibility of the default
regd getting overwritten.

Since the default reg rules will be received only once per pdev on
firmware load, the above flag based check can be replaced with a check
to see if default_regd is already set, so that we can now always update
the new_regd. Also if the new_regd is set, this will be always used to
update the reg rules for the registered phy.

69a0fcf8a9 ath11k: Avoid reg rules update during firmware recovery
During firmware recovery, the default reg rules which are
received via WMI_REG_CHAN_LIST_CC_EVENT can overwrite
the currently configured user regd.

See below snap for example,

root@OpenWrt:/# iw reg get | grep country
country FR: DFS-ETSI
country FR: DFS-ETSI
country FR: DFS-ETSI
country FR: DFS-ETSI

root@OpenWrt:/# echo assert > /sys/kernel/debug/ath11k/ipq8074\ hw2.0/simulate_f
w_crash
<snip>
[ 5290.471696] ath11k c000000.wifi1: pdev 1 successfully recovered

root@OpenWrt:/# iw reg get | grep country
country FR: DFS-ETSI
country US: DFS-FCC
country US: DFS-FCC
country US: DFS-FCC

In the above, the user configured country 'FR' is overwritten
when the rules of default country 'US' are received and updated during
recovery. Hence avoid processing of these rules in general
during firmware recovery as they have been already applied during
driver registration or after last set user country is configured.

This scenario applies for both AP and STA devices basically because
cfg80211 is not aware of the recovery and only the driver recovers, but
changing or resetting of the reg domain during recovery is not needed so
as to continue with the configured regdomain currently in use.

2167fa606c ath11k: Add support for RX decapsulation offload
Add support for rx decapsulation offload by advertising
the support to mac80211 during registration. Also ensure
the frames have the RX_FLAG_8023 flag set in decap offload
frames before passing to mac80211.

Since the packets delivered to the driver are in 802.3 format, these
can be sent to the network core with minimal processing in mac80211.
This helps in releasing some CPU cycles in the host processor and
thereby improving the performance.

Two exceptions are made before passing decap frames, one is
for EAPOL packets since mac80211 8023 fast rx for the sta
is set only after authorization, other case is for multicast
packets to validate PN in mac80211. In both the cases the
decap frames are converted to 80211 frame and sent to mac80211.

Ethernet decap can be enabled by using frame_mode modparam:

insmod ath11k frame_mode=2

b2549465cd ath11k: Replace one-element array with flexible-array member
There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code
should always use "flexible array members"[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

Refactor the code a bit according to the use of a flexible-array member in
struct scan_chan_list_params instead of a one-element array, and use the
struct_size() helper.

Also, save 25 (too many) bytes that were being allocated:

$ pahole -C channel_param drivers/net/wireless/ath/ath11k/reg.o
struct channel_param {
	u8                         chan_id;              /*     0     1 */

	/* size: 25, cachelines: 1, members: 21 */
	/* sum members: 23 */
	/* sum bitfield members: 10 bits, bit holes: 1, sum bit holes: 6 bits */
	/* last cacheline: 25 bytes */
} __attribute__((__packed__));

as previously, sizeof(struct scan_chan_list_params) was 32 bytes:

$ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o
struct scan_chan_list_params {
	u32                        pdev_id;              /*     0     4 */
	u16                        nallchans;            /*     4     2 */
	struct channel_param       ch_param[1];          /*     6    25 */

	/* size: 32, cachelines: 1, members: 3 */
	/* padding: 1 */
	/* last cacheline: 32 bytes */
};

and now with the flexible array transformation it is just 8 bytes:

$ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o
struct scan_chan_list_params {
	u32                        pdev_id;              /*     0     4 */
	u16                        nallchans;            /*     4     2 */
	struct channel_param       ch_param[];           /*     6     0 */

	/* size: 8, cachelines: 1, members: 3 */
	/* padding: 2 */
	/* last cacheline: 8 bytes */
};

This helps with the ongoing efforts to globally enable -Warray-bounds and
get us closer to being able to tighten the FORTIFY_SOURCE routines on
memcpy().

This issue was found with the help of Coccinelle and audited and fixed,
manually.

by changing the function prototype to no include the length of

6dfd20c8a6 ath11k: Fix the spectral minimum FFT bin count
User was not able to configure the spectral with the FFT bin count 32.
In all supported platforms, the expected minimum FFT bin count is 32 but
it was wrongly defined as 64. This restrict the user to not configure
down to the actually supported minimum FFT bin count. So update the
minimum FFT bin count as 32.

cc2ad75414 ath11k: Refactor spectral FFT bin size
In IPQ8074, actual FFT bin size is two bytes but hardware reports it
with extra pad size of two bytes for each FFT bin. So finally each FFT
bin advertise as four bytes size in the collected data. This FFT pad is
not advertised in IPQ6018 platform. To accommodate this different
behavior across the platforms, introduce the hw param fft_pad_sz and use
it in spectral process. Also group all the spectral params under the new
structure in hw param structure for scalable in future.

service ready ext event. Extract this NSS ratio info from service
ready ext event and save this information in ath11k_pdev_cap to
calculate NSS ratio.

Current firmware configurations support two types of NSS ratio
which is WMI_NSS_RATIO_1_NSS for QCN9074 and WMI_NSS_RATIO_1BY2_NSS
for IPQ8074. Based on this two configuration, max supported
NSS getting calculated.

151a7c12c4 Revert "brcmfmac: use ISO3166 country code and 0 rev as fallback"
This reverts commit b0b524f079.

Commit b0b524f079 ("brcmfmac: use ISO3166 country code and 0 rev
as fallback") changes country setup to directly use ISO3166 country
codes if no more specific code is configured. This was done under
the assumption that brcmfmac firmwares can handle such simple
direct mapping from country codes to firmware ccode values.

Unfortunately this is not true for all chipset/firmware combinations.
E.g. BCM4359/9 devices stop working as access point with this change,
so revert the offending commit to avoid the regression.

3fd445a4d4 brcmfmac: Replace zero-length array with flexible array member
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use "flexible array members"[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

Also, make use of the struct_size() helper in devm_kzalloc().

313bbd1990 mac80211-hwsim: fix late beacon hrtimer handling
Thomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglx
that our handling of the hrtimer here is wrong: If the timer fires
late (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot)
then it tries to actually rearm the timer at the next deadline,
which might be in the past already:

 1          2          3          N          N+1
 |          |          |   ...    |          |

 ^ intended to fire here (1)
            ^ next deadline here (2)
                                      ^ actually fired here

The next time it fires, it's later, but will still try to schedule
for the next deadline (now 3), etc. until it catches up with N,
but that might take a long time, causing stalls etc.

Now, all of this is simulation, so we just have to fix it, but
note that the behaviour is wrong even per spec, since there's no
value then in sending all those beacons unaligned - they should be
aligned to the TBTT (1, 2, 3, ... in the picture), and if we're a
bit (or a lot) late, then just resume at that point.

Therefore, change the code to use hrtimer_forward_now() which will
ensure that the next firing of the timer would be at N+1 (in the
picture), i.e. the next interval point after the current time.

The following sequence is expected from WILC chip for wakeup:
 - set wakeup bit in wakeup_reg register
 - after setting the wakeup bit, read back the clock status bit for wakeup

For SDIO/SPI modules, the wakeup sequence is the same except uses different

31f97cf9f0 rsi: Fix module dev_oper_mode parameter description
The module parameters are missing dev_oper_mode 12, BT classic alone,
add it. Moreover, the parameters encode newlines, which ends up being
printed malformed e.g. by modinfo, so fix that too.

However, the module parameter string is duplicated in both USB and SDIO
modules and the dev_oper_mode mode enumeration in those module parameters
is a duplicate of macros used by the driver. Furthermore, the enumeration
is confusing.

So, deduplicate the module parameter string and use __stringify() to
encode the correct mode enumeration values into the module parameter
string. Finally, replace 'Wi-Fi' with 'Wi-Fi alone' and 'BT' with
'BT classic alone' to clarify what those modes really mean.

c606008b70 mwifiex: Properly initialize private structure on interface type changes
When creating a new virtual interface in mwifiex_add_virtual_intf(), we
update our internal driver states like bss_type, bss_priority, bss_role
and bss_mode to reflect the mode the firmware will be set to.

When switching virtual interface mode using
mwifiex_init_new_priv_params() though, we currently only update bss_mode
and bss_role. In order for the interface mode switch to actually work,
we also need to update bss_type to its proper value, so do that.

This fixes a crash of the firmware (because the driver tries to execute
commands that are invalid in AP mode) when switching from station mode
to AP mode.

fae2aac8c7 mwifiex: Update virtual interface counters right after setting bss_type
In mwifiex_init_new_priv_params() we update our private driver state to
reflect the currently selected virtual interface type. Most notably we
set the bss_mode to the mode we're going to put the firmware in.

Now after we updated the driver state we actually start talking to the
firmware and instruct it to set up the new mode. Those commands can and
will sometimes fail, in which case we return with an error from
mwifiex_change_vif_to_*. We currently update our virtual interface type
counters after this return, which means the code is never reached when a
firmware error happens and we never update the counters. Since we have
updated our bss_mode earlier though, the counters now no longer reflect
the actual state of the driver.

This will break things on the next virtual interface change, because the
virtual interface type we're switching away from didn't get its counter
incremented, and we end up decrementing a 0-counter.

To fix this, simply update the virtual interface type counters right
after updating our driver structures, so that they are always in sync.

c2e9666cdf mwifiex: Run SET_BSS_MODE when changing from P2P to STATION vif-type
We currently handle changing from the P2P to the STATION virtual
interface type slightly different than changing from P2P to ADHOC: When
changing to STATION, we don't send the SET_BSS_MODE command. We do send
that command on all other type-changes though, and it probably makes
sense to send the command since after all we just changed our BSS_MODE.
Looking at prior changes to this part of the code, it seems that this is
simply a leftover from old refactorings.

Since sending the SET_BSS_MODE command is the only difference between
mwifiex_change_vif_to_sta_adhoc() and the current code, we can now use
mwifiex_change_vif_to_sta_adhoc() for both switching to ADHOC and
STATION interface type.

This does not fix any particular bug and just "looked right", so there's
a small chance it might be a regression.

7285eb9693 rtw88: support adaptivity for ETSI/JP DFS region
Add Energy Detected CCA (EDCCA) mechanism to detect energy on the channel.
And EDCCA support adaptivity mode now. From MIC Ordinance Regulating Radio
Equipment article 49.20, ETSI EN-300-328 and EN-301-893, the device should
be able to dynamically pause TX activity when energy detected on the air.
According to ETSI/JP DFS region, driver will set corresponding threshold
and stop TX activity if the detected energy exceeds the threshold. For now,
we support it on 8822b and 8822c first.

By default, EDCCA mechanism is turned on. For ETSI/JP DFS region, it will
turn to adaptivity mode. However, with adaptivity, if environment is too
noisy, TX may often be halted. So, a debugfs for EDCCA is added. It can
show what EDCCA mode is used currently. And EDCCA mechanism can be turned
on/off through the debugfs while debugging.

8d4fb3998c rtw88: add regulatory strategy by chip type
Realtek chips can program a specific country domain on efuse to
indicate what is the expected rtw_regulatory. For chips with a
programmed country domain, we set REGULATORY_STRICT_REG to tell
stack to consider follow-up regulatory_hint() as the superset of
our regulatory rule. Besides, on driver side, only the request via
NL80211_REGDOM_SET_BY_DRIVER, which matches programmed country
domain, will be handled to keep rtw_regulatory unchanged.

For worldwide roaming chips, i.e. ones without a specific programmed
country domain, system of distro can set expected regulatory via
NL80211_REGDOM_SET_BY_USER. With setting from it, rtw_regulatory
will handle the requests only via NL80211_REGDOM_SET_BY_USER to
follow setting from system of distro. REGULATORY_COUNTRY_IE_IGNORE
will then be set to tell stack to ignore country IE for us. The
restrictions mentioned above will remain until 00, i.e. worldwide,
is set via NL80211_REGDOM_SET_BY_USER.

On the other hand, for worldwide roamin chips, if there is no
specific regulatory set via NL80211_REGDOM_SET_BY_USER, requests
from all regulatory notifications will be handled by rtw_regulatory.
And REGULATORY_COUNTRY_IE_IGNORE won't be set.

f8509c38ec rtw88: upgrade rtw_regulatory mechanism and mapping
Mapping table from country code to rtw_regulatory, which manages tx power
limit according to countries, is updated. And mapping architecture is also
upgraded. For more precise control on tx power limit, it allows different
rtw_regulatory for different bands logically. Besides, a helper function
to query rtw_regulatory for current band under current country is provided.

For older chips, some newly added rtw_regulatory may not be configured.
To avoid that those chips have no limit on some countries mapping to a
newer rtw_regulatory after table update, a backward selection mechanism
of rtw_regulatory is introduced. It can help chips use a rtw_regulatory
which has been configured as an alternative of a newer one which is not
configured.

In addition, rtw88 actually doesn't manage channel plans by itself.
Instead, it follows them from stack. So, correct some naming about
chplan with regd, and remove the unnecessary channel control for now.

0e159d2c08 wcn36xx: Implement Idle Mode Power Save
Idle Mode Power Save (IMPS) is a power saving mechanism which when called
by wcn36xx will cause the radio hardware to enter power collapse.

This particular call maps nicely to a simple conjunction/disjunction around
IEEE80211_CONF_CHANGE_IDLE and IEEE80211_CONF_IDLE.

Here we enter idle when we are not associated with an AP. The kernel will
incrementally toggle idle on/off in the process of trying to establish a
connection, thus saving power until we are connected to the AP again, at
which point we give way to BMPS if power_save is on.

We've validated that with IMPS an apq8039 device which has the wcn36xx
module loaded but, has not authenticated with an AP will get to VMIN on
suspend and will not without IMPS.

701668d3bf wcn36xx: Fix Antenna Diversity Switching
We have been tracking a strange bug with Antenna Diversity Switching (ADS)
on wcn3680b for a while.

ADS is configured like this:
   A. Via a firmware configuration table baked into the NV area.
       1. Defines if ADS is enabled.
       2. Defines which GPIOs are connected to which antenna enable pin.
       3. Defines which antenna/GPIO is primary and which is secondary.

   B. WCN36XX_CFG_VAL(ANTENNA_DIVERSITY, N)
      N is a bitmask of available antenna.

      Setting N to 3 indicates a bitmask of enabled antenna (1 | 2).

      Obviously then we can set N to 1 or N to 2 to fix to a particular
      antenna and disable antenna diversity.

   C. WCN36XX_CFG_VAL(ASD_PROBE_INTERVAL, XX)
      XX is the number of beacons between each antenna RSSI check.
      Setting this value to 50 means, every 50 received beacons, run the
      ADS algorithm.

   D. WCN36XX_CFG_VAL(ASD_TRIGGER_THRESHOLD, YY)
      YY is a two's complement integer which specifies the RSSI decibel
      threshold below which ADS will run.
      We default to -60db here, meaning a measured RSSI <= -60db will
      trigger an ADS probe.

   E. WCN36XX_CFG_VAL(ASD_RTT_RSSI_HYST_THRESHOLD, Z)
      Z is a hysteresis value, indicating a delta which the RSSI must
      exceed for the antenna switch to be valid.

      For example if HYST_THRESHOLD == 3 AntennaId1-RSSI == -60db and
      AntennaId-2-RSSI == -58db then firmware will not switch antenna.
      The threshold needs to be -57db or better to satisfy the criteria.

   F. A firmware feature bit also exists ANTENNA_DIVERSITY_SELECTION.
      This feature bit is used by the firmware to report if
      ANTENNA_DIVERSITY_SELECTION is supported. The host is not required to
      toggle this bit to enable or disable ADS.

ADS works like this:

    A. Every XX beacons the firmware switches to or remains on the primary
       antenna.

    B. The firmware then sends a Request-To-Send (RTS) packet to the AP.

    C. The firmware waits for a Clear-To-Send (CTS) response from the AP.

    D. The firmware then notes the received RSSI on the CTS packet.

    E. The firmware then repeats steps A-D on the secondary antenna.

    F. Subsequently if the RSSI on the measured antenna is better than
       ASD_TRIGGER_THRESHOLD + the active antenna's RSSI then the
       measured antenna becomes the active antenna.

    G. If RSSI rises past ASD_TRIGGER_THRESHOLD then ADS doesn't run at
       all even if there is a substantially better RSSI on the alternative
       antenna.

What we have been observing is that the RTS packet is being sent but the
MAC address is a byte-swapped version of the target MAC. The ADS/RTS MAC is
corrupted only when the link is encrypted, if the AP is open the RTS MAC is
correct. Similarly if we configure the firmware to an RTS/CTS sequence for
regular data - the transmitted RTS MAC is correctly formatted.

Internally the wcn36xx firmware uses the indexes in the SMD commands to
populate and extract data from specific entries in an STA lookup table. The
AP's MAC appears a number of times in different indexes within this lookup
table, so the MAC address extracted for the data-transmit RTS and the MAC
address extracted for the ADS/RTS packet are not the same STA table index.

Our analysis indicates the relevant firmware STA table index is
"bssSelfStaIdx".

There is an STA populate function responsible for formatting the MAC
address of the bssSelfStaIdx including byte-swapping the MAC address.

Its clear then that the required STA populate command did not run for
bssSelfStaIdx.

So taking a look at the sequence of SMD commands sent to the firmware we
see the following downstream when moving from an unencrypted to encrypted
BSS setup.

- WLAN_HAL_CONFIG_BSS_REQ
- WLAN_HAL_CONFIG_STA_REQ
- WLAN_HAL_SET_STAKEY_REQ

Upstream in wcn36xx we have

- WLAN_HAL_CONFIG_BSS_REQ
- WLAN_HAL_SET_STAKEY_REQ

The solution then is to add the missing WLAN_HAL_CONFIG_STA_REQ between
WLAN_HAL_CONFIG_BSS_REQ and WLAN_HAL_SET_STAKEY_REQ.

No surprise WLAN_HAL_CONFIG_STA_REQ is the routine responsible for
populating the STA lookup table in the firmware and once done the MAC sent
by the ADS routine is in the correct byte-order.

This bug is apparent with ADS but it is also the case that any other
firmware routine that depends on the "bssSelfStaIdx" would retrieve
malformed data on an encrypted link.

d6dbce453b wcn36xx: handle connection loss indication
Firmware sends delete_sta_context_ind when it detects the AP has gone
away in STA mode. Right now the handler for that indication only handles
AP mode; fix it to also handle STA mode.

b515d09705 rsi: fix rate mask set leading to P2P failure
P2P client mode was only working the first time.
On subsequent connection attempts the group was successfully created but
no data was sent (no transmitted data packets were seen with a sniffer).

The reason for this was that the hardware was being configured in fixed
rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band.

In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow
the 11b rates in the 2.4GHz band which updated common->fixedrate_mask.

rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum
allowed rate, or 0xffff = auto if none was found.
However that calculation did not account for the different rate sets
allowed in the different bands leading to the error.

Fixing set_min_rate() would result in 6Mb/s being used all the time
which is not what we want either.

The reason the problem did not occur on the first connection is that
rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for
the *current* band. When it was called that was still 2.4GHz as the
switch is done later. So the when set_min_rate() was subsequently
called after the switch to 5GHz it still had a mask of zero, leading
to defaulting to auto mode.

Fix this by differentiating the case of a single rate being
requested, in which case the hardware will be used in fixed rate
mode with just that rate, and multiple rates being requested,
in which case we remain in auto mode but the firmware rate selection
algorithm is configured with a restricted set of rates.

99ac601882 rsi: fix key enabled check causing unwanted encryption for vap_id > 0
My previous patch checked if encryption should be enabled by directly
checking info->control.hw_key (like the downstream driver).
However that missed that the control and driver_info members of
struct ieee80211_tx_info are union fields.

Due to this when rsi_core_xmit() updates fields in "tx_params"
(driver_info) it can overwrite the control.hw_key, causing the result
of the later test to be incorrect.

With the current structure layout the first byte of control.hw_key is
overlayed with the vap_id so, since we only test if control.hw_key is
NULL / non NULL, a non zero vap_id will incorrectly enable encryption.

In basic STA and AP modes the vap_id is always zero so it works but in
P2P client mode a second VIF is created causing vap_id to be non zero
and hence encryption to be enabled before keys have been set.

Fix this by extracting the key presence flag to a new field in the driver
private tx_params structure and populating it first.

9b14ed6e11 rsi: fix occasional initialisation failure with BT coex
When BT coexistence is enabled (eg oper mode 13, which is the default)
the initialisation on startup sometimes silently fails.

In a normal initialisation we see
	usb 1-1.3: Product: Wireless USB Network Module
	usb 1-1.3: Manufacturer: Redpine Signals, Inc.
	usb 1-1.3: SerialNumber: 000000000001

	rsi_91x: rsi_load_9116_firmware: Loading chunk 2
	rsi_91x: Max Stations Allowed = 1

But sometimes the last log is missing and the wlan net device is
not created.

Running a userspace loop that resets the hardware via a GPIO shows the
problem occurring ~5/100 resets.

The problem does not occur in oper mode 1 (wifi only).

Adding logs shows that the initialisation state machine requests a MAC
reset via rsi_send_reset_mac() but the firmware does not reply, leading
to the initialisation sequence being incomplete.

Fix this by delaying attaching the BT adapter until the wifi
initialisation has completed.

With this applied I have done > 300 reset loops with no errors.

eb3a97a69b ath9k: fetch calibration data via nvmem subsystem
On most embedded ath9k devices (like range extenders,
routers, accesspoints, ...) the calibration data is
stored in a MTD partitions named "ART", or "caldata"/
"calibration".

Since commit 4b361cfa86 ("mtd: core: add OTP nvmem provider support"):
All MTD partitions are all automatically available through
the nvmem subsystem.

This feature - together with an nvmem cell definition either
in the platform data or via device-tree allows drivers to get
the data necessary for initializing the WIFI, without having
to wait around for the filesystem and userspace to do
the extractions.

1476ff21ab iwl: fix debug printf format strings
The variable 'package_size' is an unsigned long, and should be printed
out using '%lu', not '%zd' (that would be for a size_t).

Yes, on many architectures (including x86-64), 'size_t' is in fact the
same type as 'long', but that's a fairly random architecture definition,
and on some platforms 'size_t' is in fact 'int' rather than 'long'.

That is the case on traditional 32-bit x86.  Yes, both types are the
exact same 32-bit size, and it would all print out perfectly correctly,
but '%zd' ends up still being wrong.

And we can't make 'package_size' be a 'size_t', because we get the
actual value using efivar_entry_get() that takes a pointer to an
'unsigned long'.  So '%lu' it is.

This fixes two of the i386 allmodconfig build warnings (that is now an
error due to -Werror).

45010c080e iwlwifi: pnvm: Fix a memory leak in 'iwl_pnvm_get_from_fs()'
A firmware is requested but never released in this function. This leads to
a memory leak in the normal execution path.

Add the missing 'release_firmware()' call.
Also introduce a temp variable (new_len) in order to keep the value of
'pnvm->size' after the firmware has been released.

851c8e761c iwlwifi: bump FW API to 66 for AX devices
Start supporting API version 66 for AX devices.

Th iwlwifi FW API is frozen every 6 weeks, so we need to bump the
newest version number that the driver supports accordingly.  In this
specific case, support for new HW will only be possible with the new
FW version.  This change still keeps backwards compatibility with
older FW API versions for existing devices.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

It has been compile tested.

a847666acc mwifiex: pcie: add reset_d3cold quirk for Surface gen4+ devices
To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it
seems that putting the wifi device into D3cold is required according
to errata.inf file on Windows installation (Windows/INF/errata.inf).

This patch adds a function that performs power-cycle (put into D3cold
then D0) and call the function at the end of reset_prepare().

Note: Need to also reset the parent device (bridge) of wifi on SB1;
it might be because the bridge of wifi always reports it's in D3hot.
When I tried to reset only the wifi device (not touching parent), it gave
the following error and the reset failed:

    acpi device:4b: Cannot transition to power state D0 for parent in D3hot
    mwifiex_pcie 0000:03:00.0: can't change power state from D3cold to D0 (config space inaccessible)

This commit adds the ability to apply device-specific quirks to the

with dmi.c. We'll add identifiers to match various MS Surface devices,
which this is primarily meant for, later.

d745ca4f2c brcmfmac: pcie: fix oops on failure to resume and reprobe
When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a
hot resume and then fall back to removing the PCI device and then
reprobing. If this probe fails, the kernel will oops, because brcmf_err,
which is called to report the failure will dereference the stale bus
pointer. Open code and use the default bus-less brcmf_err to avoid this.

Commit 369956ae57 ("rtlwifi: rtl8192de: Remove redundant variable
initializations") removed the initialization of place but it appears
that this removal was in the wrong function.

_rtl92c_phy_get_rightchnlplace() returns place's value at the end of the
function so now if the if statement is false, place never gets
initialized. Add that initialization back to address the warning.

place's initialization is not necessary in
rtl92d_get_rightchnlplace_for_iqk() as place is only used within the if
statement so it can be removed, which is likely what was intended in the
first place.

7c48662b9d ath9k: fix sleeping in atomic context
The problem is that gpio_free() can sleep and the cfg_soc() can be
called with spinlocks held. One problematic call tree is:

--> ath_reset_internal() takes &sc->sc_pcu_lock spin lock
   --> ath9k_hw_reset()
      --> ath9k_hw_gpio_request_in()
         --> ath9k_hw_gpio_request()
            --> ath9k_hw_gpio_cfg_soc()

Remove gpio_free(), use error message instead, so we should make sure
there is no GPIO conflict.

Also remove ath9k_hw_gpio_free() from ath9k_hw_apply_gpio_override(),
as gpio_mask will never be set for SOC chips.

23151b9ae7 ath9k: fix OOB read ar9300_eeprom_restore_internal
Bad header can have large length field which can cause OOB.
cptr is the last bytes for read, and the eeprom is parsed
from high to low address. The OOB, triggered by the condition
length > cptr could cause memory error with a read on
negative index.

There are some sanity check around length, but it is not
compared with cptr (the remaining bytes). Here, the
corrupted/bad EEPROM can cause panic.

I was able to reproduce the crash, but I cannot find the
log and the reproducer now. After I applied the patch, the
bug is no longer reproducible.

e257d969f3 iwlwifi: mvm: don't use FW key ID in beacon protection
To check beacon protection had a mismatch of the key ID we
currently use the key ID from the firmware, but firmware
side we want to clean up the API to stop reporting this.

Instead, check the IWL_RX_MPDU_STATUS_KEY_VALID bit that
indicates that the firmware used the correct key, and if
that's set but we get invalid MIC/replay use the key ID
from the frame to look up the key and notify mac80211 of
MIC error or replay. Since both keys must have the same
cipher and thus MIC length, we can use either of them to
look up the MIC length.

a76b57311b iwlwifi: mvm: don't schedule the roc_done_wk if it is already running
When P2P roc is removed, the IWL_MVM_STATUS_NEED_FLUSH_P2P bit is set
to indicate to iwl_mvm_roc_done_wk() that the removed roc is a P2P
one, so it will flush the broadcast station and not the aux station.

However, since setting this bit and scheduling the worker is done
in roc ended flow as well as in case the roc is removed, there is
a race where the worker has already started running (but did not
test this bit yet) and then it is scheduled again. In this case,
the first run of the worker will clear this bit, and thus the second
run will find it already cleared and will try to flush and remove
the aux station by mistake.

Fix it by scheduling the worker only if this bit is not yet set. In
case this bit is already set, the worker is either running or
scheduled, so there is no need to re-schedule it.

2a8084147b iwlwifi: acpi: support reading and storing WRDS revision 1 and 2
Change the SAR profile tables storage to revision 2 regardless of the
revision we read from ACPI.  Revision 2 is a superset of revision 1,
which is in turn a superset of revision 0, so they can all be stored
inside revision 2.

Add support for reading and storing also revisions 1 and 2, whose only
difference is the number of chains and number of sub-bands.  So most
of the code revolves around passing different chain and sub-band
sizes.

With this patch we still pass only revision 0 to the firmware, but
that will be changed in a separate patch.

c6ce1c74ef iwlwifi: mvm: avoid static queue number aliasing
When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then
queue numbers are just sequentially assigned 0, 1, 2, ...
Prior to TVQM, in DQA, there were some statically allocated
queue numbers:
 * IWL_MVM_DQA_AUX_QUEUE == 1,
 * both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and
   IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and
 * IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9.

Now, these values are assigned to the members mvm->aux_queue,
mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by
default. Normally, this doesn't really matter, and if TVQM is
in fact available we override them to the real values after
allocating a queue for use there.

However, this allocation doesn't always happen. For example,
for mvm->p2p_dev_queue (== 2) it only happens when the P2P
Device interface is started, if any. If it's not started, the
value in mvm->p2p_dev_queue remains 2. This wouldn't really
matter all that much if it weren't for iwl_mvm_is_static_queue()
which checks a queue number against one of those four static
numbers.

Now, if no P2P Device or monitor interface is added then queue
2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or
mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously
returns true for it. If it then gets full, all interface queues
are stopped, instead of just backpressuring against the one TXQ
that's really the only affected one.

This clearly can lead to issues, as everything is stopped even
if just a single TXQ filled its corresponding HW queue, if it
happens to have an appropriate number (2 or 9, AUX is always
reassigned.) Due to a mac80211 bug, this also led to a situation
in which the queues remained stopped across a deauthentication
and then attempts to connect to a new AP started failing, but
that's fixed separately.

Fix all of this by simply initializing the queue numbers to
the invalid value until they're used, if TVQM is enabled, and
also setting them back to that value when the queues are later
freed again.

a6dfbd040e iwlwifi: mvm: set replay counter on key install
When installing a (new) key, set the replay counter so that
after FW restart the firmware has the correct value of the
replay counters.

This doesn't have a large effect - for frames that reach
the driver, it will do a replay check, and when installing
a new key, the counter is normally zero to start with (not
for GTK though, if joining the BSS for the first time).

Since this only affects frames handled entirely by the FW,
and that's restricted to a few unicast management frames,
the only affect here is for those after a firmware restart.

e6a70a02de wireless-drivers-next patches for v5.15
First set of patches for v5.15. This got delayed as I have been mostly
 offline for the last few weeks. The biggest change is removal of
 prism54 driver, otherwise just smaller changes.
 
 Major changes:
 
 ath5k, ath9k, ath10k, ath11k:
 
 * switch from 'pci_' to 'dma_' API
 
 brcmfmac
 
 * allow per-board firmware binaries
 
 * add support 43752 SDIO device
 
 prism54
 
 * remove the obsoleted driver, everyone should be using p54 driver instead

d816ce8744 rtw88: Remove unnecessary check code
The rtw_pci_init_rx_ring function is only ever called with a fixed
constant or RTK_MAX_RX_DESC_NUM for the "len" argument. Since this
constant is defined as 512, the "if (len > TRX_BD_IDX_MASK)" check
can never happen (TRX_BD_IDX_MASK is defined as GENMASK(11, 0) or in
other words as 4095).

So, remove this check.

The true motivation for this patch is to silence a false Coverity
warning.

to wait firmware finish preliminary work and then update the value of

function with power-saving mode, in which mode the value of
WOWLAN_WAKE_REASON register is 0xea. So driver may get 0xea value and
return fail. We use read_poll_timeout instead to check the value to avoid

f62cdab7f5 rtl8xxxu: disable interrupt_in transfer for 8188cu and 8192cu
There will be crazy numbers of interrupts triggered by 8188cu and
8192cu module, around 8000~10000 interrupts per second, on the usb
host controller. Compare with the vendor driver source code, it's
mapping to the configuration CONFIG_USB_INTERRUPT_IN_PIPE and it is
disabled by default.

Since the interrupt transfer is neither used for TX/RX nor H2C
commands. Disable it to avoid the excessive amount of interrupts
for the 8188cu and 8192cu module which I only have for verification.

090f2c5d3d mwifiex: usb: Replace one-element array with flexible-array member
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

This issue was found with the help of Coccinelle and audited and fixed,
manually.

92276c592a ray_cs: Split memcpy() to avoid bounds check warning
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

Split memcpy() for each address range to help memcpy() correctly reason
about the bounds checking. Avoids the future warning:

d6b6d1bb80 ipw2x00: Avoid field-overflowing memcpy()
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

libipw_read_qos_param_element() copies a struct libipw_info_element
into a struct libipw_qos_information_element, but is actually wanting to
copy into the larger struct libipw_qos_parameter_info (the contents of
ac_params_record[] is later examined). Refactor the routine to perform
centralized checks, and copy the entire contents directly (since the id
and len members match the elementID and length members):

struct libipw_info_element {
        u8 id;
        u8 len;
        u8 data[];
} __packed;

struct libipw_qos_information_element {
        u8 elementID;
        u8 length;
        u8 qui[QOS_OUI_LEN];
        u8 qui_type;
        u8 qui_subtype;
        u8 version;
        u8 ac_info;
} __packed;

struct libipw_qos_parameter_info {
        struct libipw_qos_information_element info_element;
        u8 reserved;
        struct libipw_qos_ac_parameter ac_params_record[QOS_QUEUE_NUM];

6f78f4a41e ipw2x00: Use struct_size helper instead of open-coded arithmetic
Dynamic size calculations (especially multiplication) should not be
performed in memory allocator function arguments due to the risk of them
overflowing. This could lead to values wrapping around and a smaller
allocation being made than the caller was expecting. Using those
allocations could lead to linear overflows of heap memory and other
misbehaviors.

To avoid this scenario, use the struct_size helper.

41b637bac0 brcmfmac: Set SDIO workqueue as WQ_HIGHPRI
This puts tasks submitted to the SDIO workqueue at the head of the queue
and runs them immediately. This gets higher RX throughput with the SDIO
bus.

This was originally submitted as [1]. The original author Wright Feng
reports

> throughput result with 43455(11ac) on 1 core 1.6 Ghz platform is
>     Without WQ_HIGGPRI TX/RX: 293/301 (mbps)
>     With    WQ_HIGHPRI TX/RX: 293/321 (mbps)

I tested this with a 43364(11bgn) on a 1 core 800 MHz platform and got
    Without WQ_HIGHPRI TX/RX: 16/19 (Mbits/sec)
    With    WQ_HIGHPRI TX/RX: 24/20 (MBits/sec)

c2dac3d2d3 brcmfmac: firmware: Fix firmware loading
The patch that would first try the board-specific firmware
had a bug because the fallback would not be called: the
asynchronous interface is used meaning request_firmware_nowait()
returns 0 immediately.

Harden the firmware loading like this:

- If we cannot build an alt_path (like if no board_type is
  specified) just request the first firmware without any
  suffix, like in the past.

- If the lookup of a board specific firmware fails, we get
  a NULL fw in the async callback, so just try again without
  the alt_path from a dedicated brcm_fw_request_done_alt_path
  callback.

- Drop the unnecessary prototype of brcm_fw_request_done.

- Added MODULE_FIRMWARE match for per-board SDIO bins, making
  userspace tools to pull all the relevant firmware files.

d249ff28b1 intersil: remove obsolete prism54 wireless driver
Commit 1d89cae1b4 ("MAINTAINERS: mark prism54 obsolete") indicated the
prism54 driver as obsolete in July 2010.

Now, after being exposed for ten years to refactoring, general tree-wide
changes and various janitor clean-up, it is really time to delete the
driver for good.

This was discovered as part of a checkpatch evaluation, investigating all
reports of checkpatch's WARNING:OBSOLETE check.

p54 replaces prism54 so users should be unaffected. There was a one off chipset
someone long ago reported that p54 didn't work with but the reporter never
followed up on that. Additionally, distributions have been blacklisting prism54
for years now.

5ff013914c brcmfmac: firmware: Allow per-board firmware binaries
After some crashes in the 3D engine (!) on the Samsung GT-I8530
it turns out that the main firmware file can be device dependent,
something that was previously only handled for the NVRAM
parameter file.

Rewrite the code a bit so we can a per-board suffixed firmware
binary as well, if this does not exist we fall back to the
canonical firmware name.

Example: a 4330 device with the OF board compatible is
"samsung,gavini". We will first try
"brcmfmac4330-sdio.samsung,gavini.bin" then "brcmfmac4330-sdio.bin"
if that does not work.

b42000e4b8 firmware: qcom_scm: Allow qcom_scm driver to be loadable as a permenent module
Allow the qcom_scm driver to be loadable as a permenent module.

This still uses the "depends on QCOM_SCM || !QCOM_SCM" bit to
ensure that drivers that call into the qcom_scm driver are
also built as modules. While not ideal in some cases its the
only safe way I can find to avoid build errors without having
those drivers select QCOM_SCM and have to force it on (as
QCOM_SCM=n can be valid for those drivers).

Reviving this now that Saravana's fw_devlink defaults to on,
which should avoid loading troubles seen before.

e9338abf0e fallthrough fixes for Clang for 5.14-rc2
Hi Linus,
 
 Please, pull the following patches that fix many fall-through
 warnings when building with Clang and -Wimplicit-fallthrough.
 
 This pull-request also contains the patch for Makefile that enables
 -Wimplicit-fallthrough for Clang, globally.
 
 It's also important to notice that since we have adopted the use of
 the pseudo-keyword macro fallthrough; we also want to avoid having
 more /* fall through */ comments being introduced. Notice that contrary
 to GCC, Clang doesn't recognize any comments as implicit fall-through
 markings when the -Wimplicit-fallthrough option is enabled. So, in
 order to avoid having more comments being introduced, we have to use
 the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang,
 will cause a warning in case a code comment is intended to be used
 as a fall-through marking. The patch for Makefile also enforces this.
 
 We had almost 4,000 of these issues for Clang in the beginning,
 and there might be a couple more out there when building some
 architectures with certain configurations. However, with the
 recent fixes I think we are in good shape and it is now possible
 to enable -Wimplicit-fallthrough for Clang. :)
 
 Thanks!

 Current release - new code bugs:
 
  - netfilter: nft_last:
      - fix incorrect arithmetic when restoring last used
      - honor NFTA_LAST_SET on restoration
 
 Previous releases - regressions:

  - sfc: ensure correct number of XDP queues; don't allow enabling the
         feature if there isn't sufficient resources to Tx from any CPU
 
  - dsa: sja1105: fix address learning getting disabled on the CPU port
 
  - mptcp: addresses a rmem accounting issue that could keep packets
         in subflow receive buffers longer than necessary, delaying
 	MPTCP-level ACKs
 
  - ip_tunnel: fix mtu calculation for ETHER tunnel devices
 
  - do not reuse skbs allocated from skbuff_fclone_cache in the napi
    skb cache, we'd try to return them to the wrong slab cache
 
  - tcp: consistently disable header prediction for mptcp
 
 Previous releases - always broken:
 
  - bpf: fix subprog poke descriptor tracking use-after-free
 
  - ipv6:
       - allocate enough headroom in ip6_finish_output2() in case
         iptables TEE is used
       - tcp: drop silly ICMPv6 packet too big messages to avoid
         expensive and pointless lookups (which may serve as a DDOS
 	vector)
       - make sure fwmark is copied in SYNACK packets
       - fix 'disable_policy' for forwarded packets (align with IPv4)
 
  - netfilter: conntrack: do not renew entry stuck in tcp SYN_SENT state
 
  - netfilter: conntrack: do not mark RST in the reply direction coming
       after SYN packet for an out-of-sync entry
 
  - mptcp: cleanly handle error conditions with MP_JOIN and syncookies
 
  - mptcp: fix double free when rejecting a join due to port mismatch
 
  - validate lwtstate->data before returning from skb_tunnel_info()
 
  - tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path
 
  - mt76: mt7921: continue to probe driver when fw already downloaded
 
  - bonding: fix multiple issues with offloading IPsec to (thru?) bond
 
  - stmmac: ptp: fix issues around Qbv support and setting time back
 
  - bcmgenet: always clear wake-up based on energy detection
 
 Misc:
 
  - sctp: move 198 addresses from unusable to private scope
 
  - ptp: support virtual clocks and timestamping
 
  - openvswitch: optimize operation for key comparison

   - sock: fix parameter order in sock_setsockopt()

  Current release - new code bugs:

   - netfilter: nft_last:
       - fix incorrect arithmetic when restoring last used
       - honor NFTA_LAST_SET on restoration

  Previous releases - regressions:

   - udp: properly flush normal packet at GRO time

   - sfc: ensure correct number of XDP queues; don't allow enabling the
     feature if there isn't sufficient resources to Tx from any CPU

   - dsa: sja1105: fix address learning getting disabled on the CPU port

   - mptcp: addresses a rmem accounting issue that could keep packets in
     subflow receive buffers longer than necessary, delaying MPTCP-level
     ACKs

   - ip_tunnel: fix mtu calculation for ETHER tunnel devices

   - do not reuse skbs allocated from skbuff_fclone_cache in the napi
     skb cache, we'd try to return them to the wrong slab cache

   - tcp: consistently disable header prediction for mptcp

  Previous releases - always broken:

   - bpf: fix subprog poke descriptor tracking use-after-free

   - ipv6:
       - allocate enough headroom in ip6_finish_output2() in case
         iptables TEE is used
       - tcp: drop silly ICMPv6 packet too big messages to avoid
         expensive and pointless lookups (which may serve as a DDOS
         vector)
       - make sure fwmark is copied in SYNACK packets
       - fix 'disable_policy' for forwarded packets (align with IPv4)

   - netfilter: conntrack:
       - do not renew entry stuck in tcp SYN_SENT state
       - do not mark RST in the reply direction coming after SYN packet
         for an out-of-sync entry

   - mptcp: cleanly handle error conditions with MP_JOIN and syncookies

   - mptcp: fix double free when rejecting a join due to port mismatch

   - validate lwtstate->data before returning from skb_tunnel_info()

   - tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path

   - mt76: mt7921: continue to probe driver when fw already downloaded

   - bonding: fix multiple issues with offloading IPsec to (thru?) bond

   - stmmac: ptp: fix issues around Qbv support and setting time back

   - bcmgenet: always clear wake-up based on energy detection

  Misc:

   - sctp: move 198 addresses from unusable to private scope

   - ptp: support virtual clocks and timestamping

   - openvswitch: optimize operation for key comparison"

4cad671979 asm-generic/unaligned: Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally architecture
 specific, with the two main variants being the "access-ok.h" version
 that assumes unaligned pointer accesses always work on a particular
 architecture, and the "le-struct.h" version that casts the data to a
 byte aligned type before dereferencing, for architectures that cannot
 always do unaligned accesses in hardware.
 
 Based on the discussion linked below, it appears that the access-ok
 version is not realiable on any architecture, but the struct version
 probably has no downsides. This series changes the code to use the
 same implementation on all architectures, addressing the few exceptions
 separately.

1a3ac5c651 brcmfmac: support parse country code map from DT
With any regulatory domain requests coming from either user space or
802.11 IE (Information Element), the country is coded in ISO3166
standard.  It needs to be translated to firmware country code and
revision with the mapping info in settings->country_codes table.
Support populate country_codes table by parsing the mapping from DT.

The BRCMF_BUSTYPE_SDIO bus_type check gets separated from general DT
validation, so that country code can be handled as general part rather
than SDIO bus specific one.

to take action when the exchange finishes, whether successfully

Add a notification to the driver on completion, i.e. call the
new method mgd_complete_tx().

To unify the two scenarios, and to add more information, make
both of them take a struct that has the duration (prepare only),
subtype (both) and success (complete only).

59c668d700 mwifiex: Avoid memset() over-write of WEP key_material
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memset(), avoid intentionally writing across
neighboring array fields.

When preparing to call mwifiex_set_keyparamset_wep(), key_material is
treated very differently from its structure layout (which has only a
single struct mwifiex_ie_type_key_param_set). Instead, add a new type to
the union so memset() can correctly reason about the size of the
structure.

Note that the union ("params", 196 bytes) containing key_material was
not large enough to hold the target of this memset(): sizeof(struct
mwifiex_ie_type_key_param_set) == 60, NUM_WEP_KEYS = 4, so 240
bytes, or 44 bytes past the end of "params". The good news is that
it appears that the command buffer, as allocated, is 2048 bytes
(MWIFIEX_SIZE_OF_CMD_BUFFER), so no neighboring memory appears to be
getting clobbered.

This new feature allows OEMs to set a special reduced power table in a

Read the variable and store it in a dram block to pass it to the

8e08e191fc iwlwifi: pcie: remove TR/CR tail allocations
The TR/CR tail data are meant to be per-queue-arrays, however,
we allocate them completely wrong (we have a separate allocation
per queue).

Looking at this more closely, it turns out that the hardware
never uses these - we have a separate free list per RX queue
and maintain a write pointer for that in a register, and the
RX itself is indicated in the RB status (rb_stts) DMA region.

Despite nothing using the tail pointers, the hardware will
unconditionally access them to write updates, even when we aren't
using CRs/TRs.

Give it dummy values that we never use/update so it can do that
without causing trouble.

The firmware can now request SMPS (due to thermal conditions), add
some code to honour such requests and bubble them up through the
stack, subject to our other SMPS constraints, e.g. from Bluetooth.

Then, if the firmware requests SMPS, then we know that it supports
a small extension to the PHY configuration API where a chain mask
of 0 means "use 1 but pick which one yourself", so in this case we
use that extension.

During firmware restart, we stay in the previous state, and the FW
will send us a notification at startup (only) if the temperature is
below the lower or above the high threshold, to sync the state.

8835a64f74 iwlwifi: mvm: don't change band on bound PHY contexts
When we have a P2P Device active, we attempt to only change the
PHY context it uses when we get a new remain-on-channel, if the
P2P Device is the only user of the PHY context.

This is fine if we're switching within a band, but if we're
switching bands then the switch implies a removal and re-add
of the PHY context, which isn't permitted by the firmware while
it's bound to an interface.

Fix the code to skip the unbind/release/... cycle only if the
band doesn't change (or we have old devices that can switch the
band on the fly as well.)

adf6a0f8c0 rtl8xxxu: avoid parsing short RX packet
One USB data buffer can contain multiple received network
packets. If that's the case, they're processed this way:
1. Original buffer is cloned
2. Original buffer is trimmed to contain only the first
   network packet
3. This first network packet is passed to network stack
4. Cloned buffer is trimmed to eliminate the first network
   packet
5. Repeat with the cloned buffer until there are no more
   network packets inside

However, if the space remaining in original buffer after
the first network packet is not enough to contain at least
another network packet descriptor, it is not cloned.

The loop parsing this packets ended if remaining space == 0.
But if the remaining space was > 0 but < packet descriptor
size, another iteration of the loop was done, processing again
the previous packet because cloning didn't happen. Moreover,
the ownership of this packet had been passed to network
stack in the previous iteration.

This patch ensures that no extra iteration is done if the
remaining size is not enough for one packet, and also avoid
the first iteration for the same reason.

Probably this doesn't happen in practice, but can happen
theoretically.

Thermal cooling device support is added to control the temperature by
throttling the data transmission for the given duration. Throttling is
done by adjusting Tx period by given percentage of time. The thermal
device allows user to configure duty cycle.

Throttling can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder

7bf0a71e83 mt76: mt7921: fix reset under the deep sleep is enabled
To fix possibly the race to access register between the WiFi reset
and the other context that is caused by explicitly cancelling ps_work
and wake_work to break PM_STATE consistency.

Deep sleep would cause the hardware into the inactive state,
so we forcely put device drv_own state before we start to reset.

The patch also ignore the reset request when the procedure is in
progress to avoid the consecutive WiFi resets.

means nss = 1 mcs = 0~9. This only applies to data frames as for other

Note that driver does not support GI configuration.

314538041b rsi: fix AP mode with WPA failure due to encrypted EAPOL
In AP mode WPA2-PSK connections were not established.

The reason was that the AP was sending the first message
of the 4 way handshake encrypted, even though no pairwise
key had (correctly) yet been set.

Encryption was enabled if the "security_enable" driver flag
was set and encryption was not explicitly disabled by
IEEE80211_TX_INTFL_DONT_ENCRYPT.

However security_enable was set when *any* key, including
the AP GTK key, had been set which was causing unwanted
encryption even if no key was avaialble for the unicast
packet to be sent.

Fix this by adding a check that we have a key and drop
the old security_enable driver flag which is insufficient
and redundant.

The Redpine downstream out of tree driver does it this way too.

Regarding the Fixes tag the actual code being modified was
introduced earlier, with the original driver submission, in
dad0d04fa7 ("rsi: Add RS9113 wireless driver"), however
at that time AP mode was not yet supported so there was
no bug at that point.

So I have tagged the introduction of AP support instead
which was part of the patch set "rsi: support for AP mode" [1]

It is not clear whether AP WPA has ever worked, I can see nothing
on the kernel side that broke it afterwards yet the AP support
patch series says "Tests are performed to confirm aggregation,
connections in WEP and WPA/WPA2 security."

One possibility is that the initial tests were done with a modified
userspace (hostapd).

3f60f46856 cw1200: Revert unnecessary patches that fix unreal use-after-free bugs
A previous commit 4f68ef64cd ("cw1200: Fix concurrency
use-after-free bugs in cw1200_hw_scan()") tried to fix a seemingly
use-after-free bug between cw1200_bss_info_changed() and
cw1200_hw_scan(), where the former frees a sk_buff pointed
to by frame.skb, and the latter accesses the sk_buff
pointed to by frame.skb. However, this issue should be a
false alarm because:

(1) "frame.skb" is not a shared variable between the above
two functions, because "frame" is a local function variable,
each of the two functions has its own local "frame" - they
just happen to have the same variable name.

(2) the sk_buff(s) pointed to by these two "frame.skb" are
also two different object instances, they are individually
allocated by different dev_alloc_skb() within the two above
functions. To free one object instance will not invalidate
the access of another different one.

Based on these facts, the previous commit should be unnecessary.
Moreover, it also introduced a missing unlock which was
addressed in a subsequent commit 51c8d24101 ("cw1200: fix missing
unlock on error in cw1200_hw_scan()"). Now that the
original use-after-free is unreal, these two commits should
be reverted. This patch performs the reversion.
