Do not cancel scan in disconnect callback. If there is an active scan,
it will be cancelled by firmware, then host driver will be properly
notified by event.
Cancelling scan in disconnect callback occasionally may lead to the
following race issue. Host is able to queue one scan after scan
abort in disconnect callback, and another scan after scan abort
in event handler. As a result, firmware receives second scan
before the first scan completes.

Now with wlcore using PM runtime, we can also add support for Linux
generic wakeirq handling for it if configured in the dts file.
The wakeirq can be configured as the second interrupt in the dts file
with interrupts-extended property where it is the padconf irq of the OOB
GPIO pin used for wlcore interrupt.
Note that eventually we should also allow configuring wlcore to use the
SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be
configured to be the padconf interrupt of the dat1 pin and not the
padconf interrupt of the OOB GPIO pin.

The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.

Finding a common channel to send an action frame out is required for
some action types. Since a loop with several scan retry is used to find
the channel, a short wait time could be considered for each attempt.
This patch reduces the wait time from 1500 to 450 msec for each action
frame scan.

Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.
This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

This patch helps to get the power save state change of each peer
connected to the AP. With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID
event, ps state of each peer is reported to user space via
debugfs.
Use the below command to get the ps state of each sta:
cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/
XX:XX:XX:XX:XX:XX/peer_ps_state
If STA is in power save state, we get the peer_ps_state value as 1.
if STA is not in power save state, we get the peer_ps_state value as 0.
If ps_state event is disabled, we get the peer_ps_state value as 2.
We can enable/disable the ps_state events using the debugfs flag
"ps_state_enable"
echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable
Y = 1 to enable and Y = 0 to disable

By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.
This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

Since commit 9d5804662c ("ath10k: retrieve MAC address from system
firmware if provided"), we support pulling our MAC address from system
firmware. Along with this, we should admit that it's possible for system
firmware to be screwed up as well, omitting the MAC address there.
Provide a fallback, such that we choose a randomly-generated MAC
address, with the local assignment bit set.
This is not a preferred mode of operation and really should only serve
the purpose of keeping the system chugging along while someone figures
out what's wrong with the system. Grepping through other wireless
drivers shows very similar fallback logic though, so why not?

The tx_status for management frames is being filled

If the first virtual interface is a station (or an AP with beacons
temporarily disabled), the beacon of the second interface needs to
occupy hardware beacon slot 0.
For some reason the beacon index was incorrectly masked with the
virtual interface beacon mask, which prevents the secondary
interface from sending beacons unless the first one also does.

We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.
When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.
We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.
To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

to directly delete a radio while temporarily releasing the spinlock,

iteration of additional radios.
Move radios about to destroy to a temporary list, and clean that up
after releasing the spinlock once iteration is complete.

32 KiB pages being held for a long time, despite only being used for

This can happen if the driver grabs one or two fragments for rx ring
refill, while other drivers use (and free up) the remaining fragments.
The 32 KiB higher-order page can only be freed once all users have freed

This is done in order not to trig the below warning in
ieee80211_rx_napi:
WARN_ON_ONCE(softirq_count() == 0);
ieee80211_rx_napi requires that softirq's are disabled during
execution.
The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.
Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully

Special HTT RX handling for high latency interfaces.
Since no DMA physical addresses are used in the RX ring
config message (this is not supported by the high latency
devices), no RX ring is allocated.
All RX skb's are allocated by the driver and passed directly
to mac80211 in the HTT RX indication handler.
A nice side effect of this is that no huge buffer will be
allocated with dma_alloc_coherent. On embedded systems with
limited memory resources, the allocation of the RX ring is
prone to fail.
Some tweaks made to "make it work":
Removal of protected bit in 802.11 header frame control field.
The chipset seems to do hw decryption but the frame_control
protected bit is still set.
This is necessary for mac80211 not to drop the frame.

Downloading firmware via BMI protocol takes too long time. For example,
a ~700K bytes firmware takes about 500ms to download via BMI protocol.
This is too long especially in suspend and resume scenario where firmware
is re-downloaded unless WoWLAN is enabled. Downloading firmware via diag CE
can reduce the time to ~40ms for a ~700K bytes firmware binary.
Ath10k driver parses the firmware to segments and downloads the segments
to the specified address directly. If the firmware is compressed or has
unsupported segments, ath10k driver will try BMI download again.
It's tested with QCA6174 hw3.2 and
firmware-6.bin_WLAN.RM.4.4.1-00111-QCARMSWP-1. QCA9377 is also affected.

To download firmware via diag interface, driver needs to write the target
memory space below 1M. It means the bit20 should be zero for the converted
address if the target memory space is below 1M. Otherwise, bit20 is one if
the target address is larger or equal to 1M space.
As downloading firmware via diag interface is only required for qca6174
and qca9377, a new specific function is introduced to convert the target
address to ce address: ath10k_pci_qca6174_targ_cpu_to_ce_addri().
This function supports to convert any target address to ce address.
It's tested with QCA6174 hw3.2 and

Delay 1ms is too long for both diag read and write operations.
This is observed when writing a big memory buffer to target or
reading a big memory buffer from target. Take writing/reading
512k bytes as example, the delay itself is 256ms as the maximum
length of every write/read is 2k size.
Reduce the delay to 50us for read and write operations.
Take the ath10k_pci_targ_cpu_to_ce_addr() out of loop and put it
in the beginning of the loop for ath10k_pci_diag_read_mem().
The ath10k_pci_targ_cpu_to_ce_addr() is to convert the address
from target cpu's perspective to CE's perspective, so it makes
no sense to convert a CE's perspective address again in the loop.
It's a wrong implementation but happens to work.
If the target address is below 1M space, then the convert in the loop
from the second time becomes wrong because the previously converted address
is larger than 1M. The counterpart ath10k_pci_diag_write_mem() has the
correct implementation.
With this change, ath10k_pci_diage_read_mem() works correctly no matter
the target address is below 1M or above 1M.
It's tested with QCA6174 hw3.2 and

Average ack rssi value is weighted average of ack rssi for
no of msdu's has been sent.
This feature is enabled by the host driver if firmware is capable.
After receiving event from host, firmware allocates the necessary
memory to store the ack_rssi for data packets during the init time.
After each successful transmission, If tx completion status is OK
and 24th bit is set in HTT message header then host will fetch the
ack_rssi else host can ignore the ack_rssi field.

To support dual-band variant of QCA9984, new extended board data (eBDF)
is introduced since existing board data ran out of space.
Below is the brief implementation & design detail,
----------------------------------------------------
1. New OTP changes to inform eBDF support in existing OTP download to
fetch board ID and chip ID. This is backward compatible and older
card sends 0 by default for eBDF support bit (bit 18 of OTP response) we
check in ath10k driver.
2. If eBDF is supported, then we need to fetch eBDF ID which is bundled
in downloaded board data. So again OTP is executed for knowing the eBDF ID.
This is done once we set 'board_data_initialized' bit. If eBDF ID
returned is zero, we continue booting with previous board data downloaded.
3. Based on the eBDF ID fetched, ath10k driver tries to download the
extended board data to a new offset ahead of already downloaded board
data address.
4. A new BD IE type, ATH10K_BD_IE_BOARD_EXT is added to differentiate in
bundling eBDF separately in board-2.bin and also to parse through
board bundle for eBDF download in ath10k boot.
5. If eBDF is not present in the board-2.bin bundle or when board ID is
zero, we do a fallback boot to "eboard.bin" in the same QCA9984/hw1.0 dir.
This is same as done to existing "board.bin" if board ID is not present
in board-2.bin bundle.
Current design is that eBDF size will be 2KB and eBDF ID will be
byte value.
Tested the above changes with dual-band variant of QCA9984 card. OTP
update needed for the test will be part of next FW release 10.4-3.6-xxxx.
Below are the logs with ath10k BOOT debugs enabled.
First OTP response :
---------------------

Enable the use of CQM_RSSI_LIST with mt76-devices. The change has been

the antenna(s) I got an event each time the RSSI went above/below a
threshold.
While I have not been able to test the change with any of the mt76
USB-devices (no access to a device), the RX RSSI management code is
shared between the two device types. Thus, CQM should also work with the

While assigning -1 to a u8 works fine, comparing with -1 does not work
as expected.
Fix this by comparing with 0xff, like is already done in some other
places.

During testing in ARM32 platforms, observed below kernel panic, as driver
accessing data beyond the allocated memory while submitting URB to USB.
Fix: Resolved this by specifying correct length by considering 64 bit
alignment. so that, USB bus driver will access only allocated memory.
Unit-test: Tested and confirm that driver bring up and scanning,
connection and data transfer works fine with this fix.

strnchr takes arguments in the order of its name: string, max bytes to
read, character to search for. Here we're passing '\n' aka 10 as the
buffer size, and searching for sizeof(buf) aka BRCMF_DCMD_SMLEN aka
256 (aka '\0', since it's implicitly converted to char) within those 10
bytes.
Just interchanging the last two arguments would still leave a bug,
because if we've been successful once, there are not sizeof(buf)
characters left after the new value of p.
Since clmver is immediately afterwards passed as a %s argument, I assume
that it is actually a properly nul-terminated string. For that case, we
have strreplace().

The problem with this copy_to_user() calls is that they don't ensure
that "size" is less than the "length" which the user provided.
Obviously, this is debugfs and "size" is normally going to be very small
so it probably doesn't matter, but this is the correct thing to do.

USB suspend handler will kill the presubmitted rx_cmd URB. This
triggers a call to the corresponding URB complete handler, which
will free the rx_cmd skb, associated with rx_cmd URB. Due to a
possible race betwen suspend handler and main thread, depicted in
'commit bfcacac6c84b ("mwifiex: do no submit URB in suspended
state")', it is possible that the rx_cmd skb will fail to get
freed. This causes a memory leak, since the resume handler will
always allocate a new rx_cmd skb.
To fix this, free the rx_cmd skb in mwifiex_usb_submit_rx_urb, if
the device is in suspended state.

There is a possible race between USB suspend and main thread:
1. After processing the command response, main thread will submit
rx_cmd URB back so as to process next command response, by
calling mwifiex_usb_submit_rx_urb.
2. During USB suspend, the suspend handler will check if rx_cmd
URB is pending(submitted) and if true, kill this URB.
There is a possible race between #1 and #2, where rx_cmd URB will
be submitted by main thread(#1) after the suspend handler check
in #2.
To fix this, check if device is already suspended in
mwifiex_usb_submit_rx_urb, in which case do not submit the URB.

length of the first argument, the compiler warns of the possibility of an
unterminated string. Using strlcpy() forces a null at the end.
