DISABLE_KEY sets the key_len to 0, firmware will not delete the keys if
key_len is 0. Changing from security mode to open mode will cause mcast

Set the proper key_len for DISABLE_KEY cmd to clear the keys in
firmware.

Whenever the MAC detects a color collision, or any of
its associated stations detects one, the firmware will
send out an event. Add the code to parse and handle
this event and pass the data up to mac80211.
The firmware does not provide an offload feature such
as the one used for CSA. The color change process is
hence triggered via the beacon offload tx completion
events sent out by firmware.
BSS color feature is enabled depending on service flag
advertised by firmware, based on which color change
functionality is invoked.

Firmware credit flow control is enabled for WMI control services,
which expects available tokens should be acquired before sending a
command to the target. Also the token gets released when firmware
receives the command.
This credit-based flow limits driver to send WMI command only
when the token available which is causing WMI commands to timeout and
return -EAGAIN, whereas firmware has enough capability to process the
WMI command. To fix this Tx starvation issue, introduce the ability to
disable the credit flow for the WMI path.
The driver sends WMI configuration for disabling credit flow to firmware
by two ways.
1. By using a global flag
(HTC_MSG_SETUP_COMPLETE_EX_ID msg type flags)
2. By using a local flag
(ATH11K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL = 1 << 3)
Ath11k uses both these configurations to disable credit flow for the
WMI path completely.
Also added a hw_param member for credit flow control by which we can
enable or disable it based on per-target basis. Currently we are disabling
credit flow for IPQ8074, IPQ6018, and QCN9074 as recommended by firmware.

In STA kickout event processing, the peer object is protected
under spin lock BH. Release this lock after picking up the vdev_id
from the peer object instead after ieee80211_report_low_ack().
This will minimize the lock hold period which will improve
performance since base_lock is used across the data path.

AUTH flag is needed when peer assoc command is sent from host in
security mode for non-assoc cases. Firmware will handle AUTH flag
when client is associating as AUTH flag will be set after key exchange.
For internally provided peer assoc commands from host, there won't be

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

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.

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.

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.

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.

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 */
u8 pwr; /* 1 1 */
u32 mhz; /* 2 4 */
/* Bitfield combined with next fields */
u32 half_rate:1; /* 4:16 4 */
u32 quarter_rate:1; /* 4:17 4 */
u32 dfs_set:1; /* 4:18 4 */
u32 dfs_set_cfreq2:1; /* 4:19 4 */
u32 is_chan_passive:1; /* 4:20 4 */
u32 allow_ht:1; /* 4:21 4 */
u32 allow_vht:1; /* 4:22 4 */
u32 allow_he:1; /* 4:23 4 */
u32 set_agile:1; /* 4:24 4 */
u32 psc_channel:1; /* 4:25 4 */
/* XXX 6 bits hole, try to pack */
u32 phy_mode; /* 8 4 */

u32 cfreq2; /* 16 4 */
char maxpower; /* 20 1 */
char minpower; /* 21 1 */
char maxregpower; /* 22 1 */
u8 antennamax; /* 23 1 */
u8 reg_class_id; /* 24 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.

When AP goes down without any indication to STA, firmware detects
missing beacon, and sends wmi roam event with reason BEACON_MISS
to the host.
Added support for STA mode to trigger disassociation from AP,
on receiving this event from firmware.

Pktlog data are different among the chipset & chipset versions.
As part of enhancing the user space script to decode the pktlog
trace events generated, it is desirable to know which chipset or
which chipset version has provided the events and thereby decode
the pktlogs appropriately.
Pktlog checksum helps to determine the chipset variant which is
given by the firmware in the struct wmi_ready_event.
Pktlog checksums are computed during the firmware build.
So, adding that pktlog checksum in the pklog trace events.

Current implementation of pdev based reo destination ring
selection is replaced by hash based ring selection so as to
ensure all the available rings are utilized for better performance.
The 4 reo destination rings are selected by the HW based on the
hash value computed from the received packet based on the 5 tuple
{ip src/ip dst/src port/dst port/protocol}. Out of the 32 hash values
used by the hw, the driver assigns 8 values per reo destination ring

Temperature sensor generates electrical analog voltage from temperature
of each chain. The analog voltage is converted to digital value through
ADC. For reading temperature values fom user space, hw monitoring device
is used.
Whenever the user requests for current temperature, the driver sends WMI
command and wait for response. For reading temperature,
cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

Thermal cooling device support is added to control the temperature by
throttling the data transmission for the given duration. Throttling is
done by suspending all data tx queues 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.
/sys/class/ieee80211/phy*/device/cooling_device.
To set duty cycle as 40%,
echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state

Currently a return path is leaking the previously allocate reg_info. Fix
this by exiting via the return path mem_free. Since the return value ret
is defaulted to 0, there is no need to re-assign ret to the 0 before
the goto.

ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first
supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k
uses mac80211 and supports AP, Station and Mesh modes.
Even though ath11k has some similar code as with ath10k (especially
the WMI layer) it was concluded to be simpler to have a "clean start"
for ath11k code base and not try to share the code with ath10k. This
makes maintenance easier and avoids major changes in ath10k, which
would have significantly increased the risk of regressions in existing
setups.
Even though the driver is very similar with ath10k but there are major
differences as well. The datapath is completely different. ath11k
supports multiple MACs, called "soc" in the firmware interface. And
there's only one WMI interface to support.
Currently ath11k supports only IEEE 802.11ac mode, but patches for
802.11ax are available and they will be submitted after ath11k is
accepted to upstream.
The firmware images are available from ath11k-firmware repository but
they will be also submitted to linux-firmware:
https://github.com/kvalo/ath11k-firmware
This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
The driver has had multiple authors who are listed in alphabetical
order below.
