2fe8ef1062 cfg80211: change netdev registration/unregistration semantics
We used to not require anything in terms of registering netdevs
with cfg80211, using a netdev notifier instead. However, in the
next patch reducing RTNL locking, this causes big problems, and
the simplest way is to just require drivers to do things better.

Change the registration/unregistration semantics to require the
drivers to call cfg80211_(un)register_netdevice() when this is
happening due to a cfg80211 request, i.e. add_virtual_intf() or
del_virtual_intf() (or if it somehow has to happen in any other
cfg80211 callback).

Otherwise, in other contexts, drivers may continue to use the
normal netdev (un)registration functions as usual.

Internally, we still use the netdev notifier and track (by the
new wdev->registered bool) if the wdev had already been added
to cfg80211 or not.

cf8480d338 ath11k: remove duplicate function declaration
Removed the duplicated peer related function declaration
from core.h since those functions are already declared in peer.h

3e6b9cf534 ath10k: increase rx buffer size to 2048
Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.

For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.

This patch now increases the maxmimum frame size from 1528 to 1656
bytes.

Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.

Fix originally found and developed by Ben Greear.

d18ba9f135 ath10k: sanitity check for ep connectivity
Function ep_rx_complete is being called without NULL checking
in ath10k_htc_rx_completion_handler. Without such check, mal-
formed packet is able to cause jump to NULL.

ep->service_id seems a good candidate for sanity check as it is
used in usb.c.

e9603f4bdc ath11k: pci: disable ASPM L0sLs before downloading firmware
Sometimes QCA6390 doesn't switch to amss state as device enters
L1ss state, so disable L0sL1s during firmware downloading.
Driver recovers the ASPM to default value in start callback
or powerdown callback.

f6f92968e1 ath11k: qmi: try to allocate a big block of DMA memory first
Not all firmware versions support allocating DMA memory in smaller blocks so
first try to allocate big block of DMA memory for QMI. If the allocation fails,
let firmware request multiple blocks of DMA memory with smaller size.

This also fixes an unnecessary error message seen during ath11k probe on
QCA6390:

ath11k_pci 0000:06:00.0: Respond mem req failed, result: 1, err: 0

ca2848022c ath9k: Postpone key cache entry deletion for TXQ frames reference it
Do not delete a key cache entry that is still being referenced by
pending frames in TXQs. This avoids reuse of the key cache entry while a
frame might still be transmitted using it.

To avoid having to do any additional operations during the main TX path
operations, track pending key cache entries in a new bitmap and check
whether any pending entries can be deleted before every new key
add/remove operation. Also clear any remaining entries when stopping the
interface.

56c5485c9e ath: Use safer key clearing with key cache entries
It is possible for there to be pending frames in TXQs with a reference
to the key cache entry that is being deleted. If such a key cache entry
is cleared, those pending frame in TXQ might get transmitted without
proper encryption. It is safer to leave the previously used key into the
key cache in such cases. Instead, only clear the MAC address to prevent
RX processing from using this key cache entry.

This is needed in particularly in AP mode where the TXQs cannot be
flushed on station disconnection. This change alone may not be able to
address all cases where the key cache entry might get reused for other
purposes immediately (the key cache entry should be released for reuse
only once the TXQs do not have any remaining references to them), but
this makes it less likely to get unprotected frames and the more
complete changes may end up being significantly more complex.

d1b0c33850 ath11k: implement suspend for QCA6390 PCI devices
Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.

At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.

During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state.  During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

5dadbe4e37 ath10k: add atomic protection for device recovery
When it has more than one restart_work queued meanwhile, the 2nd
restart_work is very easy to break the 1st restart work and lead
recovery fail.

Add a flag to allow only one restart work running untill
device successfully recovered.

It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this
flag again, because it is clear in ath10k_core_start. The function
ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do
many things and drv_start(call to ath10k_core_start) is 1st thing,
when drv_start complete, it does not mean restart complete. So it
add new flag and clear it in ath10k_reconfig_complete, because it
is the last thing called from drv_reconfig_complete of function
ieee80211_reconfig, after it, the restart process finished.

9bc3a55f4a wcn36xx: Send NULL data packet when exiting BMPS
This commit updates the BMPS exit path to be consistent with downstream in
terms of exiting BMPS mode. Downstream sets the flag to send a NULL data
frame to the host on exiting BMPS.

This will tell the AP to send any queued frames to the STA immediately.
Verified the relevant bit toggle in wireshark.

The wmi service available event has been
extended to contain extra 128 bit for new services
to be indicated by firmware.

Currently the presence of any optional TLVs in
the wmi service available event leads to a parsing
error with the below error message:

The wmi service available event parsing should
not return error for the newly added optional TLV.
Fix this parsing for service available event message.

5da7acfec5 ath11k: Reset ath11k_skb_cb before setting new flags
It was observed that the codepath for the ATH11K_SKB_HW_80211_ENCAP was
used even when the IEEE80211_TX_CTRL_HW_80211_ENCAP was not enabled for a
an skbuff. This became even more prominent when the QCAs wlan-open patchset
for ath11k [1] was applied and a sane looking fix just caused crashes when
injecting frames via a monitor interface (for example with ratechecker):

Problem is that the state of ath11k_skb_cb->flags must be considered
unknown and could contain anything when it is not manually initialized. So
it could also contain ATH11K_SKB_HW_80211_ENCAP. And this can result in the
code to assume that the ath11k_skb_cb->vif is set - even when this is not
always the case for non ATH11K_SKB_HW_80211_ENCAP transmissions.

f4d291b43f ath11k: Don't cast ath11k_skb_cb to ieee80211_tx_info.control
The driver_data area of ieee80211_tx_info is used in ath11k for
ath11k_skb_cb. The first function in the TX patch which rewrites it to
ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path
must use it for something else before it reinitializes it. Otherwise the
data has to be considered uninitialized or corrupt.

But the ieee80211_tx_info.control shares exactly the same area as
ieee80211_tx_info.driver_data and ath11k is still using it. This results in
best case in a

  ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0

or (slightly worse) in a kernel oops.

Instead, the interesting data must be moved first into the ath11k_skb_cb
and ieee80211_tx_info.control must then not be used anymore.

9af7c32cec ath10k: add target IRAM recovery feature support
This target IRAM recovery feature support is to copy target
IRAM contents available at ATH10K_MEM_REGION_TYPE_REG to host
memory for back up after firmware loaded. Target IRAM contents
are copied to wmi memory chunks allocated for the
WMI_IRAM_RECOVERY_HOST_MEM_REQ_ID and provide the wmi chunks
address to the firmware through wmi init command.

If firmware detects andy IRAM corruption through periodic
checksum validation, It will download the IRAM contents back
from the provided wmi memory chunks address using hif_memcpy.

This IRAM recovery feature prevent target assert in case of
unexpected target IRAM corruptions.

This patch also introduce a new feature flag 'iram-recovery' for
backward compatibility.

0eaa4c1d34 ath11k: add processor_id based ring_selector logic
Current ring selector logic follows round-robin scheduling,
when a process switch from one processor to another each time,
the data in the cache would have to be invalidated
and re-loaded from RAM leads to poor cache utilization.

Therefore smp_processor_id() attempt to keep processes
on the same processor via processor affinity which improves
cache utilization. Also, ring selection could be chosen round
robin when the processor_id based ring selection does not
have the resources.

bus: mhi: Remove auto-start option
There is really no point having an auto-start for channels.
This is confusing for the device drivers, some have to enable the
channels, others don't have... and waste resources (e.g. pre allocated
buffers) that may never be used.

This is really up to the MHI device(channel) driver to manage the state
of its channels.

While at it, let's also remove the auto-start option from ath11k mhi
controller.

This will cause the firmware to send a NULL packet out to the AP every 30

e24eedc09f wcn36xx: Set LINK_FAIL_TX_CNT to 1000 on all wcn36xx
The firmware parameter LINK_FAIL_TX_CNT maps to the prima configuration
file parameter gLinkFailTxCnt and is described as:

quote: " If within gLinkFailTimeout period(values is mentioned in msec) if
         FW doesn't receive acks for gLinkFailTxCnt number of packets, then
         link will be disconnected."

The downstream description sets a minimum value of 1000 a maximum value of
60000 and a default value of 6000, however it appears that unless we
actually set this value deliberately firmware defaults it to 0.

Setting this value to non-zero results in the firmware doing link
monitoring. The working example from downstream paradoxically sets the
value to 200, here we opt to set the value to the minimum stipulated in the
configuration file 1000.

In conjunction with ieee80211_hw_set(wcn->hw, CONNECTION_MONITOR); this
change effects offload of link monitoring to the firmware.

36c7c640ff ath11k: fix wmi init configuration
Assign the correct hw_op ath11k_init_wmi_config_ipq8074 to
the hw IPQ8074. Also update the correct TWT radio count.
Incorrect TWT radio count cause TWT feature fails on radio2
because physical device count is hardcoded to 2. so set
the value dynamically.

Found this during code review.

ab041d060e ath11k: Fix the hal descriptor mask
Below listed hal descriptor mask are incorrect, so modify it to correct one
 - CE destination status description meta info mask is increased from
   8 bits to 16 bits from the 0th bit position
 - Rx Reo queue duplicate count mask is decreased from 22 bits to 16 bits
 - Reo threshold status counter sum mask is increased from 24 bits to 26 bits

No functionality impact, these descriptors are currently not used in any
supported platform. But in future if someone referred these descriptor then
ended with wrong values.

9fb13b81e1 ath11k: Fix single phy hw mode
driver not able to bootup in the single radio configured board.
single phy hw mode is converted to invalid hw mode and sent to FW
through wmi init cmd. In that case driver is not receiving wmi
ready event which leads to driver bootup fail. single phy hw mode
is a valid for single radio configured board. so removed the
conversion logic.

6189be7d14 ath11k: Fix number of rules in filtered ETSI regdomain
The ath11k code will try to insert wheather rader related limits when the
DFS region is set to ETSI. For this reason, it will add two more entries in
the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list
of reg rules it returns for 2.4GHz PHYs. They will then not contain the
list of 5GHz rules and thus no wheather radar band rules were inserted by
this code.

But the code didn't fix the n_reg_rules for this regulatory domain and PHY
when this happened. This resulted in a rejection by is_valid_rd because it
found rules which start and end at 0khz. This resulted in a splat like:

  Invalid regulatory domain detected
  ------------[ cut here ]------------
  WARNING: at backports-20200628-4.4.60-9a94b73e75/net/wireless/reg.c:3721
  [...]
  ath11k c000000.wifi1: failed to perform regd update : -22

The number of rules must therefore be saved after they were converted from
the ath11k format to the ieee80211_regdomain format and not before.

02f9d3c1b9 ath11k: cold boot calibration support
cold boot calibration is the process to calibrate all the channels
during the boot-up to avoid the calibration delay during the
channel change.
During the boot-up, firmware started in cold boot calibration mode
Firmware calibrate all channels and generate CalDb(DDR).
Subsequent wifi bringup will reuse the same CalDb.
Firmware is restarted in normal mode to continue the normal operation.

caldb memory address send to firmware through the QMI message.Firmware
use this address to store the caldb data and use it until next reboot.

This will give the improvement during the channel change. But it is
increasing the boot-up time(up to 15sec depend on number of radios).
So if the user want to reduce the boot-up time and accepting for channel
change delay, user can disable this feature using the module param
cold_boot_cal=0.

14f43c5fca ath11k: search DT for qcom,ath11k-calibration-variant
Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on IPQ6018 using bus, qmi-chip-id and
qmi-board-id.

The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.

This problem was already solved on ath10k by adding a ",variant=.*" at the
end of the board name. The same functionality must also be provided for
ath11k.

The device tree requires an additional string to define the variant name

    wifi@c000000 {
        status = "okay";
        qcom,ath11k-calibration-variant = "Cigtech-WF-188";
    };

This would create the boarddata identifier for the board-2.bin search

 *  bus=ahb,qmi-chip-id=0,qmi-board-id=18,variant=Cigtech-WF-188

fd5ad4d1e9 wcn36xx: Advertise beacon filtering support in bmps
In bmps mode, beacons are filtered, and firmware is in charge
of monitoring the beacons and report changes or loss.

mac80211 must be advertised about such change to prevent it's
internal timer based beacon monitor to report beacon loss.

Fix that by setting/clearing the IEEE80211_VIF_BEACON_FILTER
vif flag on bmps entry/exit.

The timer is to check if TCL HP isn't updated to target.
The timer will postpone itself if there are TX operations
during the interval, otherwise the timer handler updates
the HP again so the index value in HP register will be
forwarded to target register, and the timer stops afterwards.

e838c14a9e ath11k: enable shadow register configuration and access
To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.

Update the shadow config whenever power up happens.

This feature is controlled by hw parameter supports_shadow_regs which is only
enabled for QCA6390.

For QCA6390, host can read and write registers below unwindowed
address directly without programming the window register. For
registers below bar0 + 4k - 32, host can read and write regardless
of the power save state. Shadow registers are located below
bar0 + 4K - 32.

Before MHI power up, there is no need to wakeup MHI so ini_done is
added to indicate it.

089ba909f8 ath11k: debugfs: fix crash during rmmod
With QCA6390 when doing rmmod the kernel crashed. The reason was that the
destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy()
accidentally had swapped the debugfs directories and
ath11k_debugfs_soc_destroy() was removing an already removed directory, which
crashed the kernel.

The source of confusion is badly named function and variable names. I think the
best way to clean this up is actually to merge the corresponding functions, but
that's for another patch. Let's first just fix the crash.

6fbd8898b3 ath11k: pci: fix rmmod crash
For QCA6390 we first need to call free_irq() and only then disable_msi(). Otherwise a
kernel BUG below will happen. Also free core, hal_srng and ce resources during
ath11k_pci_remove().

701e48a43e ath11k: add packet log support for QCA6390
Add packet log support for QCA6390, otherwise the data connection will stall
within a minute or so.  Enable it via debugfs and use trace-cmd to capture the
pktlogs.

echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter

The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.

As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.

For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

3f6e6c3291 ath11k: disable monitor mode on QCA6390
QCA6390 does not support monitor mode at the moment so disable it altogether,
using a hack as mac80211 does not support disabling it otherwise. Add a boolean
to hw_params to know if hardware supports monitor mode.

IPQ8074 continues to support monitor mode normally.

There are different versions of QCA6390. Check TCSR_SOC_HW_VERSION to make sure

This needs to be checked after ath11k_pci_claim() so move the whole switch choosing hw_ver.

As QCA6390 does not support mesh interfaces, move the interface_modes to
hw_params. Also create interface combinations dynamically so that it's easy to
change the values.

Now QCA6390 does not claim to support mesh interfaces to user space, but
IPQ8074 continues to do that.

The QCA6390 board I have, model 8291M-PR comes with an ELF board file.  To get
this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then
added this patch to check for ELF magic string in the beginning of the file.
If that is found, use type ELF.  After this the driver loads.

bc8befe6f9 ath11k: fix undefined reference to 'ath11k_debugfs_htt_ext_stats_handler'
kbuild bot reported than link fails when CONFIG_ATH11K_DEBUGFS is disabled:

drivers/net/wireless/ath/ath11k/dp_rx.c:1662: undefined reference to `ath11k_debugfs_htt_ext_stats_handler'

This was because I had missed to move the static inline version of the function
(which are used when CONFIG_ATH11K_DEBUGFS is disabled) to debufs_htt_stats.h.
Also move ath11k_debugfs_htt_stats_req() at the same time. And create a stub
also for ath11k_debugfs_htt_stats_init() for consistency, even if it's not

c695faf745 ath11k: wmi: remove redundant configuration values from init
In commit 2d4bcbed5b ("ath11k: initialize wmi config based on hw_params") the
wmi config initialisation was moved to hw_ops->wmi_init_config() but the old

is very confusing, so remove the redundant values.

And this was actually so confusing that in commit aa2092a9ba ("ath11k: add

d961fdfaa2 wcn36xx: Convert to VHT parameter structure on wcn3680
In order to send VHT parameters to wcn3680 we need to pass the extended V1
parameter structures to the firmware. These commands need to have the
version number set to 1.

This patch makes the conversion. The conversion consists of

1. Setting the version number for wcn3680 or leaving it at 0 otherwise
2. Setting the size of the packet header lower for wcn3620 and wcn3660

Once done all three chips can continue to use the same code to pass
parameters to their respective firmware. In the case of the wcn3680 the
passed structures will be slightly larger to accommodate communication of
VHT descriptors.

4e93810565 ath10k: Use bdf calibration variant for snoc targets
Board Data File (BDF) is loaded upon driver boot-up procedure.
The right board data file is identified using bus and qmi-board-id.

The problem, however, can occur when the (default) board data
file cannot fulfill with the vendor requirements and it is
necessary to use a different board data file.

Also using the chip_id for identifying the board data helps
in dealing with different variants of the board data file based
on the RF card. If the chip_id is not programmed, a default value
of 0xff will be used for parsing the board data file.

Add the support to get the variant field from DTSI and
use this information along with the chip_id to load the vendor
specific BDF.

wcn36xx_smd_config_bss_v0() and wcn36xx_smd_config_bss_v1() have been

dead code now present in wcn36xx_smd_config_bss() and happily remove one
kzalloc from the BSS config path as we do so.

Since neither wcn3620 nor wcn3660 support VHT the size of the passed

differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger

Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().

cc20ff2c6b mac80211: swap NEED_TXPROCESSING and HW_80211_ENCAP tx flags
In order to unify the tx status path, the hw 802.11 encapsulation flag
needs to survive the trip to the tx status call.
Since we don't have any free bits in info->flags, we need to move one.
IEEE80211_TX_INTFL_NEED_TXPROCESSING is only used internally in mac80211,
and only before the call into the driver.

6aea26ce5a mac80211: rework tx encapsulation offload API
The current API (which lets the driver turn on/off per vif directly) has a
number of limitations:
- it does not deal with AP_VLAN
- conditions for enabling (no tkip, no monitor) are only checked at
  add_interface time
- no way to indicate 4-addr support

In order to address this, store offload flags in struct ieee80211_vif
(easy to extend for decap offload later). mac80211 initially sets the enable
flag, but gives the driver a chance to modify it before its settings are
applied. In addition to the .add_interface op, a .update_vif_offload op is
introduced, which can be used for runtime changes.

If a driver can't disable encap offload at runtime, or if it has some extra
limitations, it can simply override the flags within those ops.

Support for encap offload with 4-address mode interfaces can be enabled
by setting a flag from .add_interface or .update_vif_offload.

In order for the firmware to process extended V1 parameters with the
addtional VHT fields added we need to first enable the feature bit DOT11AC.
Once done the version number in the HAL message header will be acted upon
by the firmware.

Extended V1 parameters are a prerequisite for 802.11ac speeds since we
cannot communicate VHT parameters to the firmware absent the extended data

d66d24ac30 ath10k: Keep track of which interrupts fired, don't poll them
If we have a per CE (Copy Engine) IRQ then we have no summary
register.  Right now the code generates a summary register by
iterating over all copy engines and seeing if they have an interrupt
pending.

This has a problem.  Specifically if _none_ if the Copy Engines have
an interrupt pending then they might go into low power mode and
reading from their address space will cause a full system crash.  This
was seen to happen when two interrupts went off at nearly the same
time.  Both were handled by a single call of ath10k_snoc_napi_poll()
but, because there were two interrupts handled and thus two calls to
napi_schedule() there was still a second call to
ath10k_snoc_napi_poll() which ran with no interrupts pending.

Instead of iterating over all the copy engines, let's just keep track
of the IRQs that fire.  Then we can effectively generate our own
summary without ever needing to read the Copy Engines.

b92aba35d3 ath10k: Add interrupt summary based CE processing
Currently the NAPI processing loops through all
the copy engines and processes a particular copy
engine is the copy completion is set for that copy
engine. The host driver is not supposed to access
any copy engine register after clearing the interrupt
status register.

This might result in kernel crash like the one below
[ 1159.220143] Call trace:
[ 1159.220170]  ath10k_snoc_read32+0x20/0x40 [ath10k_snoc]

[ 1159.220405]  kthread+0x11c/0x12c
[ 1159.220423]  ret_from_fork+0x10/0x18

To avoid such a scenario, we generate an interrupt
summary by reading the copy completion for all the
copy engine before actually processing any of them.
This will avoid reading the interrupt status register
for any CE after the interrupt status is cleared.

c6522a5076 wcn36xx: Disable bmps when encryption is disabled
For whatever reason, when connected to an open/no-security BSS,
the wcn36xx controller in bmps mode does not forward 'wake-up'
beacons despite AP sends DTIM with station AID.

Meaning that AP is not able to wakeup the station and needs to wait
for the station to wakeup by its own (TX data, keep alive pkt...),
causing serious latency issues and unexpected deauth.

When connected to AP with encryption enabled, this issue does not occur.
So a simple workaround is to only enable bmps support in that case.

Ideally, it should be propertly fixed to allow bmps support with open
BSS, whatever the issue is at driver or firmware level.

Tested on wcn3620 and wcn3680.

1fcdb567df wcn36xx: Setup starting bitrate to MCS-5
By default, after associated to an AP, the wcn36xx bitrate adjustment
algorithm starts sending data at 1Mbps, and increases the rate slowly
(1Mbps, 2Mbps, 6Mbps...) over the further TX packets.

Starting at 1Mbps usually causes the initial throughput to be really
low and the maximum possible bitrate to be reached after about hundreed
of TX packets.

That can be improved by setting a different initial bitrate for data
packets via the ENABLE_DYNAMIC_RA_START_RATE configuration value, this
value can be a legacy or MCS rate.

This patch sets the starting bitrate value to MCS-5, which seems to be
a good compromise given it can be quickly adjusted low or up if necessary.
(and based on what I observed in the wild with some mobile devices)

5973a29474 wcn36xx: Fix software-driven scan
For software-driven scan, rely on mac80211 software scan instead
of internal driver implementation. The internal implementation
cause connection trouble since it keep the antenna busy during
the entire scan duration, moreover it's only a passive scanning
(no probe request). Therefore, let mac80211 manages sw scan.

Note: we fallback to software scan if firmware does not report
scan offload support or if we need to scan the 5Ghz band (currently
not supported by the offload scan...).

7b2531d93b ath10k: Add new api to support TID specific configuration
This patch add ops for set_tid_config to support TID
specific configuration. Station specific TID configuration
will have more priority than vif specific TID configuration.
WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT service flag introduced
to notify host for TID config support. And RTS_CTS extended tid
configuration support advertised through the service flag
WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT.

TID specific noack configuration requires
aggregation should be disabled and rate for the data TID packets
should be basic rates. So, if the TID already configured
with noack policy then driver will ignore the aggregation
or TX rate related configuration for the same data TID.

In TX rate configuration should be applied with highest
preamble configuration(HT rates should not be applied
for the station which supports vht rates).

3c45f21af8 ath10k: sdio: add firmware coredump support
When firmware crashes it's possible to create a coredump for later analysis,
add support to collect the register and memory info from SDIO devices.

The coredump configuration is different between QCA6174 PCI and QCA6174 SDIO,
so add specific registers and memory regions for the latter.

QCA6174 SDIO has two methods to dump the firmware: fastdump and slowdump.
Fastdump is not supported in olded versions of firmware, and for these ath10k
will automatically select slowdump. If firmware supports fastdump, ath10k will
automatically select it. QCA6174 SDIO firmware version
WLAN.RMH.4.4.1-00017-QCARMSWPZ-2 is the first version supporting fastdump.

For slowdump, ath10k_sdio_hif_diag_read() can not be used as the diag
window has a limit value, it is 4 bytes and the dump's buffer length is larger
than it, it will trigger error. So this patch adds ath10k_sdio_read_mem() to
read 4 bytes for each time.

Example output of a firmware crash:

caf275463d ath10k: Register shutdown handler
As a part of device shutdown the smmu driver will be
stopped and henceforth any IOVA address translation
will not be done. The wlan driver, being one of the
smmu driver consumer, should stop all the dma related
activity as a part of shutdown, and thereby ensuring
that no dma activity is done once the smmu driver
shuts down.

During the device shutdown, the smmu calls shutdown
for all its consumers in order to indicate them to
stop all their dma activities.

Register the shutdown handler to stop the wlan
driver and avoid any dma operations.

ed0192f794 ath11k: wmi: put hardware to DBS mode
For QCA6390, host puts hardware to Dual Band Simultaneous (DBS) mode by default
so both 2G and 5G bands can be used. Otherwise only the 5G band can be used.
QCA6390 doesn't provide band_to_mac configuration and firmware will do the
band_to_mac map.

The ath9k driver was so far only able to rekey PTK0 keys correctly due
to the best effort queue flush added with commit 62872a9b9a
("mac80211: Fix PTK rekey freezes and clear text leak").

Add the needed queue flush and set NL80211_EXT_FEATURE_CAN_REPLACE_PTK0
to tell mac80211 that the driver can now rekey PTK0 keys correctly and
no longer needs the best effort flush.

Effectively this prevents mac80211 to warn when rekeying a PTK0 key
only.

727fae1478 ath11k: enable internal sleep clock
On x86 and other non-qcom platforms, host needs to explicitly tell the firmware
to use the internal sleep clock. Some QCA6390 modules have OTP burnt with
external sleep clock selected, and these modules can't work expectedly unless
firmware selects internal sleep clock.

Add a field to hw_params to support this difference.

f44dd33e63 ath11k: fix memory OOB access in qmi_decode
The decoded_size is wrongly assigned in ath11k_qmi_msg_handlers and it results
in out of boundary access in qmi_decode. The correct decoded_size should be
calculated from the related ind_msg structure.

This issue is exposed with QCA6390 because it needs 11 small memory chunks
which are stored in qmi_wlanfw_request_mem_ind_msg_v01 and hence the
decoded_size exceeds the wrongly assigend decoded_size.

26f3a021b3 ath11k: allocate smaller chunks of memory for firmware
On x86 it's sometimes difficult to allocate a large contigous DMA

In ath11k_qmi_msg_mem_request_cb() the error handling was cleaned up to avoid
an unused variable warning. Also changed the test from (ret < 0) to just (ret)
as the functions don't return any positive values.

6eb6ea5138 ath11k: add board file support for PCI devices
PCI devices like QCA6390 load the board file differently, add support for that
and the method is chosen using bus_params variables.

Add support to create board name for different targets.  This board name is
used to parse the board data from board-2.bin for ahb/pci based targets.

As struct target_mem_chunk::vaddr was changed from 'u32' to 'u32 *' in
ath11k_qmi_assign_target_mem_chunk() vaddr assignments were changed to NULL to
avoid a compilation warning. IPQ8074 does not use the vaddr field for anything
so that change does not affect functionality.

At the moment this only supports board files with BIN type. Support for ELF
type, which seems to be more popular on QCA6390 devices, needs to be added later.

db04b755ed ath10k: correct the array index from mcs index for HT mode for QCA6174
The mcs index of HT mode is 0 to 31, please refer http://mcsindex.com/.
Its spatial stream(Nss) number is from 1 to 4, mcs index is 0~7 for
Nss=1, 8~15 for Nss=2, 16~23 for Nss=3 and 24~31 is for Nss=4.

The mcs is reported from firmware in wmi_tlv_peer_stats_info of
event WMI_TLV_PEER_STATS_INFO_EVENTID, its range is from 0~15 for
QCA6174 SDIO and PCIe. It is for both Nss=1 and Nss=2, and it has 2
rate table supported_ht_mcs_rate_nss1 and supported_ht_mcs_rate_nss2
in ath10k, they are for Nss=1 and Nss=2, each table has 8 rates.

It need to find the matched row number with the mcs index, for example,
mcs index is 2, it is <=7, so it is Nss=1, and match row 2 in table of
Nss=1. If mcs index is 12, it is >= 8 and <= 15, so it is Nss=2, it
match row 4(12-8) in table of Nss=2. If mcs index is >=16, it is for
Nss=3/4, it need to add rate table, so it is not support in current
ath10k.

This patch is to find the row number in rate table of Nss=1 or Nss=2
with the mcs index reported from firmware.

This patch only effect the chips which supports_peer_stats_info of its
hw_params is true, it is true only for QCA6174 currently.

1cd6ba8ae3 ath10k: remove return for NL80211_STA_INFO_TX_BITRATE
ath10k_sta_statistics is used to report many info to iw wlan0 link,
if it return for empty legacy and nss of arsta->txrate, then the other
stats after it will not be set.

It has 4 bit to set after the return:
NL80211_STA_INFO_TX_FAILED
NL80211_STA_INFO_RX_BITRATE
NL80211_STA_INFO_TX_BITRATE
NL80211_STA_INFO_TX_RETRIES

This patch not effect the info of above 4 bit for all hardware, reason
as below:

NL80211_STA_INFO_TX_FAILED is only for htt.disable_tx_comp is true, it
is for QCA6174 SDIO.

NL80211_STA_INFO_RX_BITRATE and NL80211_STA_INFO_TX_BITRATE are both
set in ath10k_mac_sta_get_peer_stats_info, it is only enabled for chips
which supports_peer_stats_info is true in hw_params, recently only for
QCA6174 SDIO, NL80211_STA_INFO_TX_BITRATE is set again in function
ath10k_mac_sta_get_peer_stats_info because the value which parsed from
arsta->tx_rate_code and arsta->tx_bitrate_kbps is correct for QCA6174
SDIO and PCIe, and the value arsta->txrate is not correct for QCA6174
SDIO and PCIe, so it need to set again with the correct value.

NL80211_STA_INFO_TX_RETRIES is use value of arsta->tx_retries, it is set
in ath10k_update_per_peer_tx_stats, which accumulate the retry_pkts in
HTT message from firmware, if the chips not support this feature, then
it is always 0 after accumulate, then iw wlan0 station dump always show
0 for retry count. If not set NL80211_STA_INFO_TX_RETRIES here, then it
is still 0, so the result is same, then set NL80211_STA_INFO_TX_RETRIES
has no effect.

e39f32afc6 ath10k: add wmi service peer stat info for wmi tlv
ath10k_sta_statistics is used to report info for iw wlan0 link,
it check ath10k_peer_stats_enabled, and ath10k_peer_stats_enabled
check WMI_SERVICE_PEER_STATS bit of ar->wmi.svc_map. SVCMAP() for
WMI_SERVICE_PEER_STATS was defined only for wmi_10x_svc_map and
wmi_10_4_svc_map interfaces, it missed in wmi_tlv_svc_map, so it is
not usable for iw wlan0 link for wmi tlv interface.

If firmware report WMI_TLV_SERVICE_PEER_STATS_INFO for wmi tlv, then
enable the WMI_SERVICE_PEER_STATS bit in ath10k, and then it pass check
in ath10k_peer_stats_enabled and ath10k_sta_statistics pass check.

2fd3c8f34d ath10k: start recovery process when payload length exceeds max htc length for sdio
When simulate random transfer fail for sdio write and read, it happened
"payload length exceeds max htc length" and recovery later sometimes.

Test steps:
1. Add config and update kernel:
CONFIG_FAIL_MMC_REQUEST=y
CONFIG_FAULT_INJECTION=y
CONFIG_FAULT_INJECTION_DEBUG_FS=y

2. Run simulate fail:
cd /sys/kernel/debug/mmc1/fail_mmc_request
echo 10 > probability
echo 10 > times # repeat until hitting issues

3. It happened payload length exceeds max htc length.
[  199.935506] ath10k_sdio mmc1:0001:1: payload length 57005 exceeds max htc length: 4088
....
[  264.990191] ath10k_sdio mmc1:0001:1: payload length 57005 exceeds max htc length: 4088

4. after some time, such as 60 seconds, it start recovery which triggered
by wmi command timeout for periodic scan.
[  269.229232] ieee80211 phy0: Hardware restart was requested
[  269.734693] ath10k_sdio mmc1:0001:1: device successfully recovered

The simulate fail of sdio is not a real sdio transter fail, it only
set an error status in mmc_should_fail_request after the transfer end,
actually the transfer is success, then sdio_io_rw_ext_helper will
return error status and stop transfer the left data. For example,
the really RX len is 286 bytes, then it will split to 2 blocks in
sdio_io_rw_ext_helper, one is 256 bytes, left is 30 bytes, if the
first 256 bytes get an error status by mmc_should_fail_request,then
the left 30 bytes will not read in this RX operation. Then when the
next RX arrive, the left 30 bytes will be considered as the header
of the read, the top 4 bytes of the 30 bytes will be considered as
lookaheads, but actually the 4 bytes is not the lookaheads, so the len
from this lookaheads is not correct, it exceeds max htc length 4088
sometimes. When happened exceeds, the buffer chain is not matched between
firmware and ath10k, then it need to start recovery ASAP. Recently then
recovery will be started by wmi command timeout, but it will be long time
later, for example, it is 60+ seconds later from the periodic scan, if
it does not have periodic scan, it will be longer.

Start recovery when it happened "payload length exceeds max htc length"
will be reasonable.

This patch only effect sdio chips.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

18c25b4019 ath: drop unnecessary list_empty
list_for_each_entry{_safe} is able to handle an empty list.
The only effect of avoiding the loop is not initializing the
index variable.
Drop list_empty tests in cases where these variables are not
used.

Note that list_for_each_entry{_safe} is defined in terms of
list_first_entry, which indicates that it should not be used on an
empty list.  But in list_for_each_entry{_safe}, the element obtained
by list_first_entry is not really accessed, only the address of its
list_head field is compared to the address of the list head, so the
list_first_entry is safe.

The semantic patch that makes this change for the list_for_each_entry
case is as follows: (http://coccinelle.lip6.fr/)

<smpl>
@@
expression x,e;
statement S;
identifier i;
@@

-if (!(list_empty(x)))

fdf21cc371 wcn36xx: Add TX ack support
The controller is capable of reporting TX indication which can be used
to report TX ack when IEEE80211_TX_CTL_REQ_TX_STATUS is set.
The support was only partially implemented.

The firmware can be configured for reporting event when a packet is
acked, without specifying which packet though. In order to send a
packet flagged with TX status callback, we need to stop the queue,
submit the packet and wait for the firmware ack event. Then the queue
can be restarted and mac80211 status callback called.

In case the packet is not acked, no ack event will be received,
therefore a timeout mechanism is introduced to restart the queue
and call the status cb in case no event is received after a 100ms.

ffe835aa5b wcn36xx: Fix multiple AMPDU sessions support
Several AMPDU sessions can be started, e.g. for different TIDs.
Currently the driver does not take care of the session ID when
requesting block-ack (statically set to 0), which leads to never
block-acked packet with sessions other than 0.

Fix this by saving the session id when creating the ba session and
use it in subsequent ba operations.

This issue can be reproduced with iperf in two steps (tid 0 strem
then tid 6 stream).

1.0 iperf -s                                # wcn36xx side
1.1 iperf -c ${IP_ADDR}                     # host side

Then

2.0 iperf -s -u -S 0xC0                     # wcn36xx side

Make this safer by inverting the polarity from 'disabled' to
'enabled'.

a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

First set of patches for v5.9. This comes later than usual as I was
 offline for two weeks. The biggest change here is moving Microchip
 wilc1000 driver from staging. There was an immutable topic branch with
 one commit moving the whole driver and the topic branch was pulled
 both to staging-next and wireless-drivers-next. At the moment the only
 reported conflict is in MAINTAINERS file, so I'm hoping the move
 should go smoothly.
 
 Other notable changes are ath11k getting 6 GHz band support and rtw88
 supporting RTL8821CE. And there's also the usual fixes, API changes
 and cleanups all over.
 
 Major changes:
 
 wilc1000
 
 * move from drivers/staging to drivers/net/wireless/microchip
 
 ath11k
 
 * add 6G band support
 
 * add spectral scan support
 
 iwlwifi
 
 * make FW reconfiguration quieter by not using warn level
 
 rtw88
 
 * add support for RTL8821CE

1cfd3426ef ath10k: Fix NULL pointer dereference in AHB device probe
This fixes a NULL pointer dereference in the probe path for AHB devices.
There attr parameter in the ath10k_ce_alloc_pipe() function is not
initialized, but accessed. This function is called by
ath10k_pci_setup_resource() which is called by ath10k_ahb_probe().

The struct ath10k_pci is also used for AHB devices and not only for PCI
devices.

The initialization of the new members of struct ath10k_pci is moved to
ath10k_pci_setup_resource() which is used by the PCI and the AHB code.

This also fixes a use after free bug in ath10k_pci_remove() when ar_pci
is accessed after ath10k_core_destroy() was called, which calls
ieee80211_free_hw() and frees this memory.

This fixes the following bug seen with backports-5.8-rc2 on OpenWrt on a
IPQ4019 device:

bad60b8d1a ath10k: check idx validity in __ath10k_htt_rx_ring_fill_n()
The idx in __ath10k_htt_rx_ring_fill_n function lives in
consistent dma region writable by the device. Malfunctional
or malicious device could manipulate such idx to have a OOB
write. Either by
    htt->rx_ring.netbufs_ring[idx] = skb;
or by
    ath10k_htt_set_paddrs_ring(htt, paddr, idx);

The idx can also be negative as it's signed, giving a large
memory space to write to.

It's possibly exploitable by corruptting a legit pointer with
a skb pointer. And then fill skb with payload as rougue object.

Part of the log here. Sometimes it appears as UAF when writing
to a freed memory by chance.

9a8ab2bfb6 ath9k: Check the return value of pcie_capability_read_*()
On failure pcie_capability_read_dword() sets it's last parameter, val
to 0. However, with Patch 14/14, it is possible that val is set to ~0 on
failure. This would introduce a bug because (x & x) == (~0 & x).

This bug can be avoided without changing the function's behaviour if the
return value of pcie_capability_read_dword is checked to confirm success.

Check the return value of pcie_capability_read_dword() to ensure success.

3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

045790b7bc wil6210: account for napi_gro_receive never returning GRO_DROP
The napi_gro_receive function no longer returns GRO_DROP ever, making
handling GRO_DROP dead code. This commit removes that dead code.
Further, it's not even clear that device drivers have any business in
taking action after passing off received packets; that's arguably out of
their hands. In this case, too, the non-gro path didn't bother checking
the return value. Plus, this had some clunky debugging functions that
duplicated code from elsewhere and was generally pretty messy. So, this
commit cleans that all up too.

720e5c03e5 ath10k: provide survey info as accumulated data
It is expected that the returned counters by .get_survey are monotonic
increasing. But the data from ath10k gets reset to zero regularly. Channel
active/busy time are then showing incorrect values (less than previous or
sometimes zero) for the currently active channel during successive survey
dump commands.

example:

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            54995 ms
  	channel busy time:              432 ms
  	channel receive time:           0 ms
  	channel transmit time:          59 ms
  ...

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            32592 ms
  	channel busy time:              254 ms
  	channel receive time:           0 ms
  	channel transmit time:          0 ms
  ...

The correct way to handle this is to use the non-clearing
WMI_BSS_SURVEY_REQ_TYPE_READ wmi_bss_survey_req_type. The firmware will
then accumulate the survey data and handle wrap arounds.

count is already updating from peer statistics for SDIO devices.

8f9ed93d09 ath10k: Wait until copy complete is actually done before completing
On wcn3990 we have "per_ce_irq = true".  That makes the
ath10k_ce_interrupt_summary() function always return 0xfff. The
ath10k_ce_per_engine_service_any() function will see this and think
that _all_ copy engines have an interrupt.  Without checking, the
ath10k_ce_per_engine_service() assumes that if it's called that the
"copy complete" (cc) interrupt fired.  This combination seems bad.

Let's add a check to make sure that the "copy complete" interrupt
actually fired in ath10k_ce_per_engine_service().

This might fix a hard-to-reproduce failure where it appears that the
copy complete handlers run before the copy is really complete.
Specifically a symptom was that we were seeing this on a Qualcomm
sc7180 board:
  arm-smmu 15000000.iommu: Unhandled context fault:
  fsr=0x402, iova=0x7fdd45780, fsynr=0x30003, cbfrsynra=0xc1, cb=10

Even on platforms that don't have wcn3990 this still seems like it
would be a sane thing to do.  Specifically the current IRQ handler
comments indicate that there might be other misc interrupt sources
firing that need to be cleared.  If one of those sources was the one
that caused the IRQ handler to be called it would also be important to
double-check that the interrupt we cared about actually fired.

bff621fd11 ath11k: Send multiple scan_chan_list messages if required
With addition of 6Ghz channels, it is possible that wmi buffer size can
exceed the maximum wmi buffer size. So iterate over the channel list,
and send multiple messages till channel list is empty.
Also mark PSC channel flag for 6GHz channels accordingly.

If 'thermal_cooling_device_register()' fails, we must undo what has been

returning directly

In case of error in 'ath11k_thermal_register()', the previous
'thermal_cooling_device_register()' call must also be undone. Move the
'ar->thermal.cdev = cdev' a few lines above in order for this to be done
in 'ath11k_thermal_unregister()' which is called in the error handling
path.

ec431188b4 wcn36xx: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

which is creating a race where stats_req is being accessed
for filling in second message after the memory is already
freed in release operation. Fix this by issuing completion
once all the messages are received and processed. Driver

The last addition to the struct ignored the comments and added
new members behind the array that must remain last.

Change it to a flexible-array member and move it last again to
make it work correctly, prevent the same thing from happening
again (all compilers warn about flexible-array members in the
middle of a struct) and get it to build without warnings.

103dc3dab2 carl9170: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

c730c47717 ath10k: Remove msdu from idr when management pkt send fails
Currently when the sending of any management pkt
via wmi command fails, the packet is being unmapped
freed in the error handling. But the idr entry added,
which is used to track these packet is not getting removed.

Hence, during unload, in wmi cleanup, all the entries
in IDR are removed and the corresponding buffer is
attempted to be freed. This can cause a situation where
one packet is attempted to be freed twice.

Fix this error by rmeoving the msdu from the idr
list when the sending of a management packet over
wmi fails.

14dd3a71cc ath11k: Replace zero-length array with flexible-array

variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;

};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

52f274b519 ath11k: fix resource unavailability for htt stats after peer stats display
htt stats are not working after htt peer stats display
and also after htt peer stats reset. Trying to dump htt
stats shows "Resource temporarily unavailable".
This is because of "ar->debug.htt_stats.stats_req" member is being
consecutively used for all htt stats without being reset
during the previous usage. Hence assigning NULL to this member
after freeing the allocated memory fixes the issue.

stop running case of MAC random address scan and then the case fail.

d8d20845c7 ath9k: add calibration timeout for AR9002
ADC & I/Q calibrations could take infinite time to comple, since they
depend on received frames. In particular the I/Q mismatch calibration
requires receiving of OFDM frames for completion. But in the 2.4GHz
band, a station could receive only CCK frames for a very long time.

And while we wait for the completion of one of the mentioned
calibrations, the NF calibration is blocked. Moreover, in some
environments, I/Q calibration is unable to complete until a correct
noise calibration will be performed due to AGC behaviour.

In order to avoid delaying NF calibration on forever, limit the maximum
duration of ADCs & I/Q calibrations. If the calibration is not completed
within the maximum time, it will be interrupted and a next calibration
will be performed. The code that selects the next calibration has been
reworked to the loop so incompleted calibration will be respinned later.

А maximum calibration time of 30 seconds was selected to give the
calibration enough time to complete and to not interfere with the long
(NF) calibration.

Run tested with AR9220.

ded6ff15a1 ath9k: invalidate all calibrations at once
Previously after the calibration validity period is over,
calibrations are invalidated in a one at time manner. So, for AR9002
family, which has three calibrations, the full recalibration interval
becomes 3 x ATH_RESTART_CALINTERVAL. And each next calibration will be
separated by the ATH_RESTART_CALINTERVAL time from a previous one.

It seems like it is better to do whole recalibration at once. Also, this
change makes the driver behaviour a little simpler. So, invalidate all
calibrations at once at the end of the calibration validity interval.

This change affects only AR9002 chips family, since the AR9003 utilize
only a single calibration.

2bb7027b64 ath9k: interleaved NF calibration on AR9002
NF calibration and other elements of long calibration are usually faster
than ADCs & I/Q calibrations due to independence of receiption of the
OFDM signal. Moreover sometime I/Q calibration can not be completed at
all without preceding NF calibration. This is due to AGC, which has a
habit to block a weak signal without regular NF calibration. Thus, we do
not need to deferr the long calibration forever.

So, if the long calibration is requested, then deferr the ADCs & I/Q
calibration(s) and run the longcal (the NF calibration in particular) to
obtain fresh noise data.

Run tested with AR9220.

41ba50fd6c ath9k: do not miss longcal on AR9002
Each of AGC & I/Q calibrations can take a long time. Long calibration
and NF calibration in particular are forbiden for parallel run with
ADC & I/Q calibrations. So, the chip could not be ready to perform the
long calibration at the time of request. And a request to perform the
long calibration may be lost.

In order to fix this, preserve the long calibration request as a
calibration state flag and restore the long calibration request each
time the calibration function is called again (i.e. on each subsequent
ivocation of the short calibration).

This feature will be twice useful after the next change, which will
make it possible to start the long calibration before all ADCs & I/Q
calibrations are completed.

d6cae2bc19 ath9k: fix AR9002 ADC and NF calibrations
ADC calibration is only required for a 80 MHz sampling rate (i.e. for
40 MHz channels), when the chip utilizes the pair of ADCs in interleved
mode. Calibration on a 20 MHz channel will never be completed.

Previous channel check is trying to exclude all channels where the
calibration will get stuck. It effectively blocks the calibration run
for HT20 channels, but fails to exclude 20 MHz channels without HT (e.g.
legacy mode channels).

Fix this issue by reworking the channel check to explicitly allow ADCs
gain & DC offset calibrations for HT40 channels only. Also update the
complicated comment to make it clear that these calibrations are for
multi-ADC mode only.

Stuck ADCs calibration blocks the NF calibration, what could make it
impossible to work in a noisy evironment: too big Rx attentuation,
invalid RSSI value, etc. So this change is actually more of a NF
calibration fix rather then the ADC calibration fix.

Run tested with AR9220.

When tx complete is disabled, all tx status will be set with status
HTT_TX_COMPL_STATE_ACK and indicate to mac80211 by ieee80211_tx_status,
then it does not have the statistics for retries and failed packets.
count of tx retries and tx failed of command "iw wlan0 station dump"
are both 0. If tx complete is not disabled, then firmware report the
tx status and ath10k indicate the status to mac80211, then mac80211
save the statistics and command "iw wlan0 station dump" show them.

for example:
localhost ~ # iw dev wlan0 station dump
Station 3c:28:6d:96:fd:69 (on wlan0)
	inactive time:	5 ms
	rx bytes:	1325012
	rx packets:	6477
	tx bytes:	85264
	tx packets:	518
	tx retries:	0
	tx failed:	0

This patch only effect chips with tx complete disabled, e.g. SDIO.

with this patch, output of command "iw dev wlan0 station dump":
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  608 ms
        rx bytes:       180366
        rx packets:     991
        tx bytes:       98765577
        tx packets:     64624
        tx retries:     14682
        tx failed:      47086

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

4913e67563 ath10k: enable rx duration report default for wmi tlv
When run command "iw dev wlan0 station dump", the rx duration is 0.
When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of
statsis not set by default, so firmware do not report rx duration.

one sample:
localhost # iw wlan0 station dump
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  48 ms
        rx bytes:       21670
        rx packets:     147
        tx bytes:       11529
        tx packets:     100
        tx retries:     88
        tx failed:      36
        beacon loss:    1
        beacon rx:      31
        rx drop misc:   47
        signal:         -72 [-74, -75] dBm
        signal avg:     -71 [-74, -75] dBm
        beacon signal avg:      -71 dBm
        tx bitrate:     54.0 MBit/s MCS 3 40MHz
        rx bitrate:     1.0 MBit/s
	rx duration:    0 us

This patch enable firmware's extened flag of stats by setting flag
WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in
ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID.

After apply this patch, rx duration show value with the command:
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  883 ms
        rx bytes:       44289
        rx packets:     265
        tx bytes:       10838
        tx packets:     93
        tx retries:     899
        tx failed:      103
        beacon loss:    0
        beacon rx:      78
        rx drop misc:   46
        signal:         -71 [-74, -76] dBm
        signal avg:     -70 [-74, -76] dBm
        beacon signal avg:      -70 dBm
        tx bitrate:     54.0 MBit/s MCS 3 40MHz
        rx bitrate:     1.0 MBit/s
        rx duration:    358004 us

This patch do not have side effect for all chips, because function
ath10k_debug_fw_stats_request is already exported to debugfs
"fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition
checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

5cb899dd5b ath11k: fix reo flush send
we are sending the reo flush command for the deleted peer
tid after the ageout period reaches 1 second. This handling
causes reo ring get full when more than 128 clients are
disconnected continuously. so added the count for flush list
and reo flush command is triggered after the list count reaches
the threshold value, it is configured as 64 (half of the reo ring).
This will avoid the situation where reo ring get full.
