6aafa1c2d3 wifi: ath11k: fix memory leak in WMI firmware stats
Memory allocated for firmware pdev, vdev and beacon statistics
are not released during rmmod.

Fix it by calling ath11k_fw_stats_free() function before hardware
unregister.

While at it, avoid calling ath11k_fw_stats_free() while processing
the firmware stats received in the WMI event because the local list
is getting spliced and reinitialised and hence there are no elements
in the list after splicing.

cf036c416e wifi: ath11k: don't use %pK
According to Documentation/core-api/printk-formats.rst %pK should not be used
with printk(), so switch back to using just %p. printk() will hash the address
so addresses are not leaked to user space.

b43310e44e wifi: ath11k: factory test mode support
Add support to process factory test mode commands (FTM) for calibration.
By default firmware start with NORMAL mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.

When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state
is set to Test Mode. If the FTM command or event length is greater
than 256 bytes, it will be broken down into multiple segments and
encoded with TLV header if it is segmented commands, else it is sent
to firmware as it is.

On receiving UTF event from firmware, if it is segmented event, the driver
will wait until it receives all the segments and notify the complete
data to user application. In case the segmented sequence are missed or
lost from the firmware, driver will skip the already received partial data.

In case of unsegmented UTF event from firmware, driver notifies the
data to the user application as it comes. Applications handles
the data further.

Command to boot in ftm mode:

insmod ath11k ftm_mode=1

91dce40914 wifi: ath11k: Use list_count_nodes()
ath11k_wmi_fw_stats_num_vdevs() and ath11k_wmi_fw_stats_num_bcn() really
look the same as list_count_nodes(), so use the latter instead of hand
writing it.

The first ones use list_for_each_entry() and the other list_for_each(), but
they both count the number of nodes in the list.

While at it, also remove to prototypes of non-existent functions.
Based on the names and prototypes, it is likely that they should be
equivalent to list_count_nodes().

Compile tested only.

447b0398a9 wifi: ath11k: Fix invalid management rx frame length issue
The WMI management rx event has multiple arrays of TLVs, however the common
WMI TLV parser won't handle multiple TLV tags of same type.
So the multiple array tags of WMI management rx TLV is parsed incorrectly
and the length calculated becomes wrong when the target sends multiple
array tags.

Add separate TLV parser to handle multiple arrays for WMI management rx
TLV. This fixes invalid length issue when the target sends multiple array
tags.

Above information is helpful in debugging the issues with power save clients.

This patch also add trace log support for PS timekeeper to track the PS state
change of the peers alongs with the peer MAC address and timestamp.

Use the below commands to get the above power save information,

To know the time_since_station_in_power_save:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/current_ps_duration

To know power_save_duration:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/total_ps_duration

To reset the power_save_duration of all stations connected to AP:
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath11k/reset_ps_duration

To enable/disable the ps_timekeeper:
echo Y > /sys/kernel/debug/ieee80211/phyX/ath11k/ps_timekeeper_enable
Y = 1 to enable and Y = 0 to disable.

To record PS timekeeer logs after enabling ps_timekeeper:

Tx power used to transmit each packet. If driver wants to know the
final Tx power being used at firmware level, it can leverage from
firmware pdev stats.

Move firmware stats out of debugfs context in order to leverage
the final Tx power reported in it even when debugfs is disabled.

b7b6f86149 wifi: ath11k: Include STA_KEEPALIVE_ARP_RESPONSE TLV header by default
In current code STA_KEEPALIVE_ARP_RESPONSE TLV header is included only
when ARP method is used, this causes firmware always to crash when wowlan
is enabled because firmware needs it to be present no matter ARP method
is used or not.

Fix this issue by including STA_KEEPALIVE_ARP_RESPONSE TLV header by
default.

Also fix below typo:
  s/WMI_TAG_STA_KEEPALVE_ARP_RESPONSE/WMI_TAG_STA_KEEPALIVE_ARP_RESPONSE/

7d992bd461 wifi: ath11k: Add support to connect to non-transmit MBSSID profiles
Add support to connect to a non-transmit MBSSID AP profile.

Non-transmit MBSSID profile parameters are passed to the firmware
via WMI VDEV UP command and this helps firmware to track MBSSID
profile within the multi-BSS beacon and report beacon loss if
any.

WCN6750, QCA6390 & WCN6855 firmwares have the support and hence
enable the support on these hardwares.

9e2747c31e wifi: ath11k: Add TWT debugfs support for STA interface
Currently TWT debugfs files required for manually testing the
TWT feature are created only for the AP interfaces; these debugfs
hooks are also required for the station interfaces in order to
test the TWT feature manually, therefore create these debugfs
hooks for station iftype as well.

In the case of station interfaces, TWT is entirely handled in the
firmware based on input parameters passed to it during association
via TWT enable WMI command. In order to manually test this feature,
firmware expects to first disable the TWT feature and then send the
enable command with sta_cong_timer_ms parameter set to 0.
This is true for WCN6750, QCA6390 & WCN6855 hardwares.

1d7f514577 ath11k: Designating channel frequency when sending management frames
In case of Passpoint, the WLAN interface may be requested to
remain on a specific channel and then to send some management
frames on that channel. Now chanfreq of wmi_mgmt_send_cmd is set
as 0, as a result firmware may choose a default but wrong channel.
Fix it by assigning chanfreq field with the designated channel.

This change only applies to WCN6855 and QCA6390, other chips are

0f84a156aa ath11k: Handle keepalive during WoWLAN suspend and resume
With WoWLAN enabled and after sleeping for a rather long time,
we are seeing that with some APs, it is not able to wake up
the STA though the correct wake up pattern has been configured.
This is because the host doesn't send keepalive command to
firmware, thus firmware will not send any packet to the AP and
after a specific time the AP kicks out the STA.

Fix this issue by enabling keepalive before going to suspend
and disabling it after resume back.

[  278.064050] ath11k_pci 0000:05:00.0: failed to request fw stats: -110

Reason is:
When running disconnect operation, sta_info removed from local->sta_hash
by __sta_info_destroy_part1() from __sta_info_flush(), after this,
ieee80211_find_sta_by_ifaddr() which called by
ath11k_wmi_tlv_fw_stats_data_parse() and ath11k_wmi_tlv_rssi_chain_parse()
cannot find this station, then failed log printed.

steps are like this:
1. when disconnect from AP, __sta_info_destroy() called __sta_info_destroy_part1()
and __sta_info_destroy_part2().

2. in __sta_info_destroy_part1(),  it has "sta_info_hash_del(local, sta)"
and "list_del_rcu(&sta->list)", it will remove the ieee80211_sta from the
list of ieee80211_hw.

3. in __sta_info_destroy_part2(), it called drv_sta_state()->ath11k_mac_op_sta_state(),
then peer->sta is clear at this moment.

4. in __sta_info_destroy_part2(), it then called sta_set_sinfo()->drv_sta_statistics()
->ath11k_mac_op_sta_statistics(), then WMI_REQUEST_STATS_CMDID sent to firmware.

5. WMI_UPDATE_STATS_EVENTID reported from firmware, at this moment, the
ieee80211_sta can not be found again because it has remove from list in
step2 and also peer->sta is clear in step3.

6. in __sta_info_destroy_part2(), it then called cleanup_single_sta()->
sta_info_free()->kfree(sta), at this moment, the ieee80211_sta is freed
in memory, then the failed log will not happen because function
ath11k_mac_op_sta_state() will not be called.

Actually this print log is not a real error, it is only to skip parse the
info, so change to skip print by default debug setting.

b6f6301041 ath11k: Do not put HW in DBS mode for WCN6750
Though WCN6750 is a single PDEV device, it is not a
DBS solution. So, do not put HW in DBS mode for WCN6750.

652f69ed9c ath11k: Add support for SAR
Add ath11k_mac_op_set_bios_sar_specs() to ath11k_ops, this function is called
when user space application calls NL80211_CMD_SET_SAR_SPECS. ath11k also
registers SAR type and frequency ranges to wiphy so user space can query SAR
capabilities.

This feature is currently enabled for WCN6855.

e2e23a7917 ath11k: add support for extended wmi service bit
When the WMI service bits are reported from firmware they are divided into
multiple segments, with 128 bits in each segment. The first segment is
processed by ath11k_wmi_service_bitmap_copy(), the second segment is processed
by ath11k_service_available_event() with WMI_TAG_SERVICE_AVAILABLE_EVENT. When
the service bit exceed 256 bits, then firmware reports it by tag
WMI_TAG_ARRAY_UINT32 in WMI_SERVICE_AVAILABLE_EVENTID.

Currently ath11k does not process the third segment. Upcoming features
need to know if firmware support is available for the features, so add
processing of the third segment.

1f682dc9fb ath11k: reduce the wait time of 11d scan and hw scan while add interface
Currently ath11k will wait 11d scan complete while add interface in
ath11k_mac_op_add_interface(), when system resume without enable
wowlan, ath11k_mac_op_add_interface() is called for each resume, thus
it increase the resume time of system. And ath11k_mac_op_hw_scan()
after ath11k_mac_op_add_interface() also needs some time cost because
the previous 11d scan need more than 5 seconds when 6 GHz is enabled,
then the scan started event will indicated to ath11k after the 11d
scan completed.

While 11d scan/hw scan is running in firmware, if ath11k update channel
list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel
the current scan which is running, it lead the scan failed. The patch
commit 9dcf6808b2 ("ath11k: add 11d scan offload support") used
finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d
scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid
the scan fail.

Add wait operation before ath11k update channel list, function
ath11k_reg_update_chan_list() will wait until the current 11d scan/hw
scan completed. And remove the wait operation of start 11d scan and
waiting channel list complete in hw scan. After these changes, resume
time cost reduce about 5 seconds and also hw scan time cost reduced
obviously, and scan failed not seen.

The 11d scan is sent to firmware only one time for each interface added
in mac.c, and it is moved after the 1st hw scan because 11d scan will
cost some time and thus leads the AP scan result update to UI delay.
Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and
priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the
11d scan which sent after hw scan will cancel the hw scan in firmware,
so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which
is in front of the 11d scan, thus it will not happen scan cancel in
firmware.
