99944b7306 iwlwifi: mvm: stop static queues correctly
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

48e775e66e iwlwifi: mvm: add support for 32kHz external clock indication
In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.

There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.

Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.

Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

2ae48edcf7 iwlwifi: pcie: fix TX while flushing
When flushing TX queues no new TX should go into the system.
However, in the following scenario we get TX:
1. Queues are stopped and there are packets in overflow queue
2. Station is removed and flush begins
3. Flush empties space, and reclaim path TXes SKB from overflow
   queue.

Note that the fact the queues are stopped during the process
doesn't matter - the packet will be TXed since the TX path
doesn't care if TX queues are stopped or not, just if there is
space in the queue, which there is, since we just freed a
packet.

A fix here is rather complicated, since the flow is very racy.

Change code not to warn if we are TXing from overflow TX.
In case there is TX from both overflow TX and TX path we will
miss a warning we optimally had, but we can live with that.

Make sure we don't return before overflow queue is empty, otherwise
we will think queues are empty, but they will be refilled, resulting
with assert.

2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.

Trigger field ignore_default was changed to override_trig.
The first byte of the field indicates the driver to override existing
configuration or keep the previous one
The second byte of the field indicated the driver to replace the regions
of the previous trigger or to append new regions to it.

Change the way the active triggers are maintained to support trigger
override in different apply points.
Do this by making a trigger that updates at runtime by the
triggers that are being used in the different apply points.

In case of an assert, the driver does not reconfigure the triggers
and uses the old configuration which leads to undefined behavior.
Solve this by clearing the triggers in assert recovery flow.

4920ce3bf7 ath10k: add dynamic vlan support
Multicast/broadcast traffic destined for a particular vlan group will
always be encrypted in software. To enable dynamic VLANs, it requires
driver support for sending software encrypted packets.

In ath10k, sending software encrypted frames is allowed only when we insmod
the driver with cryptmode param set to 1, this configuration disables
hardware crypto and enables RAW mode implicitly. Since, enabling raw
mode has performance impact, this cannot be considered as an ideal
solution for supporting VLANs in the driver.

As an alternative take, in this approach, cryptographic keys for
unicast traffic (per peer PTKs) and keys for non-vlan group traffic
will be configured in hardware, allowing hardware encryption for unicast
and non-vlan group traffic. Only vlan group traffic will be encrypted in
software and pushed to the target with encap mode set to RAW in the TX
descriptors.

Not all firmwares can support this type of key configuration(having few
keys installed in hardware and few only in software); for this purpose a
new WMI service flag "WMI_SERVICE_PER_PACKET_SW_ENCRYPT" is introduced to
advertise this support.

Also, adding the logic required to send sw encrypted frames in raw mode.

25733c4e67 ath10k: pci: use mutex for diagnostic window CE polling
The DIAG copy engine is only used via polling, but it holds a spinlock
with softirqs disabled. Each iteration of our read/write loops can
theoretically take 20ms (two 10ms timeout loops), and this loop can be
run an unbounded number of times while holding the spinlock -- dependent
on the request size given by the caller.

As of commit 39501ea641 ("ath10k: download firmware via diag Copy
Engine for QCA6174 and QCA9377."), we transfer large chunks of firmware
memory using this mechanism. With large enough firmware segments, this
becomes an exceedingly long period for disabling soft IRQs. For example,
with a 500KiB firmware segment, in testing QCA6174A, I see 200 loop
iterations of about 50-100us each, which can total about 10-20ms.

In reality, we don't really need to block softirqs for this duration.
The DIAG CE is only used in polling mode, and we only need to hold
ce_lock to make sure any CE bookkeeping is done without screwing up
another CE. Otherwise, we only need to ensure exclusion between
ath10k_pci_diag_{read,write}_mem() contexts.

This patch moves to use fine-grained locking for the shared ce_lock,
while adding a new mutex just to ensure mutual exclusion of diag
read/write operations.

Tested on QCA6174A, firmware version WLAN.RM.4.4.1-00132-QCARMSWPZ-1.

05e7ba24b1 ath10k: implement set_base_macaddr to fix rx-bssid mask in multiple APs conf
Many integrated QCA9984 WiFis in various IPQ806x platform routers
from various vendors (Netgear R7800, ZyXEL NBG6817, TP-LINK C2600,
etc.) have either blank, bogus or non-unique MAC-addresses in
their calibration data.

As a result, OpenWrt utilizes a discouraged binary calibration data
patching method that allows to modify the device's MAC-addresses right
at the source. This is because the ath10k' firmware extracts the MAC
address from the supplied radio/calibration data and issues a response
to the ath10k linux driver. Which was designed to take the main MAC in
ath10k_wmi_event_ready().

Part of the "setting an alternate MAC" issue was already tackled by a
patch from Brian Norris:
commit 9d5804662c
("ath10k: retrieve MAC address from system firmware if provided")
by allowing the option to specify an alternate MAC-address with the
established device_get_mac_address() function which extracts the right
address from DeviceTree/fwnode mac-address or local-mac-address
properties and saves it for later.

However, Ben Greear noted that the Qualcomm's ath10k firmware is liable
to not properly calculate its rx-bssid mask in this case. This can cause
issues in the popluar "multiple AP with a single ath10k instance"
configurations.

To improve MAC address handling, Felix Fietkau suggested to call
pdev_set_base_macaddr_cmdid before bringing up the first vif and
use the first vif MAC address there. Which is in ath10k_core_start().

This patch implement Felix Fietkau's request to
"call pdev_set_base_macaddr_cmdid before bringing up the first vif".
The pdev_set_base_macaddr_cmdid is already declared for all devices
and version. The driver just needed the support code for this
function.

capability, then driver requests authentication offload to user-space
software using cfg80211_external_auth_request call. From that point,
auth frame exchange is performed transparently for driver: user-space
software sends/receives mgmt frames using mgmt_tx/mgmt_frame_register
cfg80211 callbacks. As soon as authenitcation is completed, user-space
software notifies driver about its status using external_auth cfg80211

e665988be2 brcmfmac: support monitor frames with the hardware/ucode header
So far there were two monitor frame formats:
1) 802.11 frames (with frame (sub)type & all addresses)
2) 802.11 frames with the radiotap header

Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in
discovering a new format being used. It seems (almost?) identical to the
one known from ucode used in SoftMAC devices which is most likely the
same codebase anyway.

While new firmwares will /announce/ radiotap header support using the
"rtap" fw capability string it seems no string was added for the new
ucode header format.

All above means that:
1) We need new format support when dealing with a received frame
2) A new feature bit & mapping quirks have to be added manually

As for now only an empty radiotap is being created. Adding support for
extracting some info (band, channel, signal, etc.) is planned for the
future.

So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).

This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

cdb78e5af4 ath10k: fix hw-restart crash inject mode for WCN3990
The hw-restart crash inject mode is a special mode, where
there is no crash generated in the firmware, but instead
the driver restarts the firmware. In order to restart WCN3990
firmware, the driver needs to send qmi_wlan_disable message
followed by the qmi_wlan_enable message to the WCN3990 firmware.

Currently the qmi_wlan_disable message is not sent to
the WCN3990 firmware when hw-restart crash is injected,
which causes the firmware to crash when the driver sends
qmi_wlan_enable message during ath10k_restart.

Send qmi_wlan_disable to the WCN3990 firmware when the
hw-restart crash is injected via debugfs.

4b6e9f3fe1 ath9k: eeprom: Use scnprintf instead of snprintf
Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.

1) Uses of size += snprintf(buf, SIZE - size, fmt, ...)  In this case,
if snprintf would have written more characters than what the buffer
size (SIZE) is, then size will end up larger than SIZE. In later uses
of snprintf, SIZE - size will result in a negative number, leading to
problems. Note that size might already be too large by using size =
snprintf before the code reaches a case of size += snprintf.

2) If size is ultimately used as a length parameter for a copy back to
user space, then it will potentially allow for a buffer overflow and
information disclosure when size is greater than SIZE. When the size is
used to index the buffer directly, we can have memory corruption. This
also means when size = snprintf... is used, it may also cause problems
since size may become large. Copying to userspace is mitigated by the
HARDENED_USERCOPY kernel configuration.

The solution to these issues is to use scnprintf which returns the number
of characters actually written to the buffer, so the size variable will
never exceed SIZE.

5b9030cee1 ath10k: Set DMA address mask to 35 bit for WCN3990
WCN3990 is a 37-bit target but can address memory range
only upto 35 bits. The 36th bit is used to control the
smmu/iommu translation and the 37th bit is used by the
internal bus masters to access the wifi subsystem internal
SRAM. With the DMA mask set to 37i-bit, the host driver
can get 37-bit dma address, which leads to incorrect
address access in the target.

Hence the host driver can used addresses upto 35-bit
for WCN3990. Fix the dma mask for wcn3990 to 35-bit,

dbf592f3d1 iwlwifi: mvm: fix RFH config command with >=10 CPUs
If we have >=10 (logical) CPUs, our command size exceeds the
internal buffer size and the command fails; fix that by using
IWL_HCMD_DFL_NOCOPY for the command that's allocated anyway.

While at it, also fix the leak of cmd, and use struct_size()
to calculate its size.

b8a7547d77 iwlwifi: fix send hcmd timeout recovery flow
Both iwl_trans_fw_error and iwl_force_nmi initiate async recovery flow.
Calling them both is redundant and causing a race.

Solve this by removing the call to iwl_trans_fw_error.

9deb52c68f iwlwifi: dbg_ini: align struct iwl_fw_ini_region_cfg to the FW
New fields were added to struct iwl_fw_ini_region_cfg.
add those field and apply the changes the result from this change

offset field is used to differentiate between the different LMACs
and any memory access to the region addresses should be
base_addr + offset.

A fifo struct is to hold the meta data needed for fifo regions

Also move range_data_size and num_of_ranges into a struct under the
union to be aligned to the struct in the FW.
