Subject: [PATCH 002/120] ath11k: fix 4-addr tx failure for AP and STA modes
Ath11k FW requires peer parameter WMI_PEER_USE_4ADDR to be set for
4-addr peers allowing 4-address frame transmission to those peers.
Add ath11k driver callback for sta_set_4addr() to queue new workq
set_4addr_wk only once based on new boolean, use_4addr_set.
sta_set_4addr() will be called during 4-addr STA association cases
applicable for both AP and STA modes.
In ath11k_sta_set_4addr_wk(),
AP mode:
WMI_PEER_USE_4ADDR will be set for the corresponding
associated 4-addr STA(s)
STA mode:
WMI_PEER_USE_4ADDR will be set for the AP to which the
4-addr STA got associated.

Subject: [PATCH 003/120] ath11k: fix 4addr multicast packet tx
In 4addr, AP wired backbone to STA wired backbone ping fails due to ARP
request not getting answered. Here 4addr ARP multicast packet is sent in
3addr, so that 4addr STA not honouring the 3addr ARP multicast packet.
Fix this issue by sending out multicast packet in 4addr format, firmware
expects peer meta flag instead of vdev meta flag in Tx descriptor.

Subject: [PATCH 009/120] ath11k: monitor mode clean up to use separate APIs
If monitor interface is enabled in co-exist mode, only local traffic are
captured. It's caused by missing monitor vdev in co-exist mode. So,
monitor mode clean up is done with separate Monitor APIs. For this,
introduce flags monitor_started and monitor_vdev_created.

From f552d6fd2f27ce9430c74482c46272838e2de688 Mon Sep 17 00:00:00 2001

Subject: [PATCH 011/120] ath11k: add support for 80P80 and 160 MHz bandwidth
For 160 MHz, nss_ratio_enabled flag is added to indicate firmware
supports sending NSS ratio information from firmware as a part of
service ready ext event. Extract this NSS ratio info from service
ready ext event and save this information in ath11k_pdev_cap to
calculate NSS ratio.
Current firmware configurations support two types of NSS ratio
which is WMI_NSS_RATIO_1_NSS for QCN9074 and WMI_NSS_RATIO_1BY2_NSS
for IPQ8074. Based on this two configuration, max supported
NSS getting calculated.
Move ath11k_peer_assoc_h_phymode() before ath11k_peer_assoc_h_vht()
to get arg->peer_phymode updated.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-00097-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01467-QCAHKSWPL_SILICONZ-1

Subject: [PATCH 012/120] ath11k: Refactor spectral FFT bin size
In IPQ8074, actual FFT bin size is two bytes but hardware reports it
with extra pad size of two bytes for each FFT bin. So finally each FFT
bin advertise as four bytes size in the collected data. This FFT pad is
not advertised in IPQ6018 platform. To accommodate this different
behavior across the platforms, introduce the hw param fft_pad_sz and use
it in spectral process. Also group all the spectral params under the new
structure in hw param structure for scalable in future.

Subject: [PATCH 014/120] ath11k: Fix the spectral minimum FFT bin count
User was not able to configure the spectral with the FFT bin count 32.
In all supported platforms, the expected minimum FFT bin count is 32 but
it was wrongly defined as 64. This restrict the user to not configure
down to the actually supported minimum FFT bin count. So update the
minimum FFT bin count as 32.

According to analysis from gcc developers, this is a glitch in the
way gcc tracks the size of struct members. This should really get
fixed in gcc, but it's also easy to work around this instance
by changing the function prototype to no include the length of
the array.

Subject: [PATCH 017/120] ath11k: use hw_params to access board_size and
cal_offset
Reuse board_size from hw_params, add cal_offset to hw params.
This patch is clean up only, there is no change in functionality.
cal_size was unused, so remove that.

Subject: [PATCH 018/120] ath11k: clean up BDF download functions
In current code, AHB/PCI uses two separate functions to download
BDF file. Refactor code and make a common function to send QMI BDF
download request for both AHB and PCI devices. This patch has no
functional change.

Subject: [PATCH 020/120] ath11k: add caldata download support from EEPROM
Firmware updates EEPROM support capability in QMI FW caps, send QMI BDF
download request message with file type EEPROM, to get caldata download
from EEPROM. Firmware takes more time to update cal data from EEPROM, so
increase QMI timeout.

Subject: [PATCH 021/120] ath11k: Replace one-element array with flexible-array
member
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 cfreq1; /* 12 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.

Subject: [PATCH 024/120] ath11k: Add support for RX decapsulation offload
Add support for rx decapsulation offload by advertising
the support to mac80211 during registration. Also ensure
the frames have the RX_FLAG_8023 flag set in decap offload
frames before passing to mac80211.
Since the packets delivered to the driver are in 802.3 format, these
can be sent to the network core with minimal processing in mac80211.
This helps in releasing some CPU cycles in the host processor and
thereby improving the performance.
Two exceptions are made before passing decap frames, one is
for EAPOL packets since mac80211 8023 fast rx for the sta
is set only after authorization, other case is for multicast
packets to validate PN in mac80211. In both the cases the
decap frames are converted to 80211 frame and sent to mac80211.

Subject: [PATCH 025/120] ath11k: Fix pktlog lite rx events
Fix sending rx_buf_sz to ath11k_dp_tx_htt_rx_filter_setup()
to enable pktlog full or lite mode. Depending on mode update the
trace buffer with log type full/lite.
Pktlog lite is a lighter version of pktlog. This can be used to capture
PPDU stats. These are useful for firmware performance debugging.
pktlog lite dumps are enabled using,

Subject: [PATCH 026/120] ath11k: Update pdev tx and rx firmware stats
Update the fields of pdev tx and tx firmware stats structure.
Missing fields resulted in wrong fw stats to be displayed as below.
root@OpenWrt:/# cat /sys/kernel/debug/ath11k/
ipq8074\ hw2.0/mac0/fw_stats/pdev_stats | grep Illegal
Illegal rate phy errors 36839112
Note that this struct was missing its members from initial driver
support and this change doesn't introduce/modify the structure for
firmware changes.

Subject: [PATCH 029/120] ath11k: Add vdev start flag to disable hardware
encryption
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.

Subject: [PATCH 030/120] ath11k: Assign free_vdev_map value before
ieee80211_register_hw
Firmware crash is seen randomly, because of sending wrong vdev_id
in vdev_create command. This is due to free_vdev_map value being 0.
free_vdev_map is getting assigned after ieee80211_register_hw. In
some race conditions, add_interface api is getting called before
assigning value to free_vdev_map. Fix this by assigning free_vdev_map
before ieee80211_register_hw.
Also, moved ar->cc_freq_hz and ar->txmgmt_idr initialization before
ieee80211_register_hw to avoid such race conditions.

Subject: [PATCH 031/120] ath11k: Fix crash during firmware recovery on reo cmd
ring access
In scenario when a peer is disassociating, there could be
multiple places where a reo cmd ring is accessed, such as
during aggregation teardown, tid queue cleanup, etc.
When this happens during firmware recovery where accessing of FW/HW
resources/registers is not recommended, accessing reo cmd ring in
this case could lead to crash or undefined behaviour.
Hence avoid this by checking for corresponding flag to avoid
accessing reo cmd ring during firmware recovery.
Sample crash:

Subject: [PATCH 032/120] ath11k: Avoid "No VIF found" warning message
Facing below warning prints when we do wifi down in multiple VAPs scenario.
warning print:
ath11k c000000.wifi: No VIF found for vdev 2
...
ath11k c000000.wifi: No VIF found for vdev 0
In ath11k_mac_get_arvif_by_vdev_id(), we iterate all the radio to get the
arvif for the requested vdev_id through ath11k_mac_get_arvif().
ath11k_mac_get_arvif() throws a warning message if the given vdev_id is
not found in the given radio. So to avoid the warning message, add
the allocated_vdev_map cross check against the given vdev_id before using
ath11k_mac_get_arvif() to ensure that vdev_id is allocated in the
given radio.

Subject: [PATCH 033/120] ath11k: Add wmi peer create conf event in
wmi_tlv_event_id
When the driver sends a peer create cmd, the firmware responds with
WMI_PEER_CREATE_CONF_EVENTID to confirm the firmware received
WMI_PEER_CREATE_CMDID. Since the peer create conf event is not handled
in ath11k_wmi_tlv_op_rx, we are getting unknown event id warning prints
during peer creation.
Add WMI_PEER_CREATE_CONF_EVENTID in wmi_tlv_event_id and handle
the same as unsupported event id under wmi logs.

Subject: [PATCH 037/120] ath11k: re-enable ht_cap/vht_cap for 5G band for
WCN6855
WCN6855 uses single_pdev_only, so it supports both the 5G and 6G bands
in the same ath11k/pdev and it needs to enable ht_cap/vht_cap for the 5G
band, otherwise it will downgrade to non-HT mode for the 5G band. Some
chips like QCN9074 only support the 6G band, not the 5G band, and use
the flag ar->supports_6ghz which is true to discard ht_cap/vht_cap.

Subject: [PATCH 038/120] ath11k: enable 6G channels for WCN6855
For some chips such as WCN6855, single_pdev_only is set in struct
ath11k_hw_params which means ath11k calls ieee80211_register_hw() only
once and create only one device interface, and that device interface
supports all 2G/5G/6G channels.
ath11k_mac_setup_channels_rates() sets up the channels and it is called
for each device interface. It is called only once for single_pdev_only,
and then set up all channels for 2G/5G/6G. The logic of
ath11k_mac_setup_channels_rates() is not suitable for single_pdev_only,
it leads to all 6G channels being disabled for the device interface
which is single_pdev_only such as WCN6855.
Add channel frequency checks for the 6G band and enable the 6G channels
properly based on what is supported by the chip.

Subject: [PATCH 039/120] ath11k: copy cap info of 6G band under
WMI_HOST_WLAN_5G_CAP for WCN6855
WCN6855 has 2 phys, one is 2G, another is 5G/6G, so it should copy the
cap info of 6G band under the check of WMI_HOST_WLAN_5G_CAP as well as
for the 5G band. Some chips like QCN9074 only have 6G, not have 2G and
5G, and this 6G capability is also under WMI_HOST_WLAN_5G_CAP, so this
change will not disturb it.

There are MSDUs whose length are invalid. For example,
attackers may inject on purpose truncated A-MSDUs with
invalid MSDU length.
Such MSDUs are marked with an err bit set in rx attention
tlvs, so we can check and drop them.

Subject: [PATCH 041/120] ath11k: Fix inaccessible debug registers
Current code clears debug registers after SOC global reset performed
in ath11k_pci_sw_reset. However at that time those registers are
not accessible due to reset, thus they are actually not cleared at all.
For WCN6855, it may cause target fail to initialize. This issue can be
fixed by moving clear action ahead.
In addition, on some specific platforms, need to add delay to wait
those registers to become accessible.

Subject: [PATCH 046/120] ath11k: Change masking and shifting in htt stats
In debugfs_htt_stats.c, masking and shifting is done to get
stats values. Instead use GENMASK and FIELD_GET to improve
code readability and maintenance.

Subject: [PATCH 047/120] ath11k: add HTT stats support for new stats
Add HTT stats support for,
29-ATH11K_DBG_HTT_EXT_STATS_PEER_CTRL_PATH_TXRX_STATS:
Used to dump the control path txrx stats for each connected peer.
Usage:
echo 29 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/netdev\:wlan0/stations/
<sta mac>/htt_peer_stats.
31-ATH11K_DBG_HTT_EXT_STATS_PDEV_TX_RATE_TXBF_STATS:
Used to dump the per pdev tx rate txbf stats.
Usage:
echo 31 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
32-ATH11k_DBG_HTT_EXT_STATS_TXBF_OFDMA:
Used to dump the TXBF ofdma stats for all ofdma users.
Usage:
echo 32 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
37-ATH11K_DBG_HTT_EXT_PHY_COUNTERS_AND_PHY_STATS:
Used to dump the mac and phy txrx counts and phy stats like per chain rssi
and ANI level.
Usage:
echo 37 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats

Subject: [PATCH 049/120] ath11k: indicate scan complete for scan canceled when
scan running
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
event for unknown vdev" print for the above case.

Subject: [PATCH 050/120] ath11k: indicate to mac80211 scan complete with
aborted flag for ATH11K_SCAN_STARTING state
Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo assert > /sys/kernel/debug/ath11k/qca6490\ hw2.0/simulate_fw_crash
immediately after step 1.
result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)
reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath11k_mac_op_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath11k_mac_scan_finish() which is called from
ath11k_core_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH11K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.
Indicate scan complete with aborted flag to mac80211 for
ATH11K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.

Currently A-MPDU aggregation parameters are not being configured

parameters from station's capabilities received in association
request and send to firmware. Without this, A-MPDU aggregation
is not happening in 6 GHz band.

Local variable mpdu_buf is assigned only once, to a constant value, making it
effectively constant throughout its scope. If this is not the intent, examine
the logic to see if there is a missing assignment that would make mpdu_buf not
remain constant.

Fix this by removing mpdu_buf and unreachable code.

Variable fw_size is being assigned a value that is never read and
being re-assigned a new value in the next statement. The assignment
is redundant and can be removed.

Subject: [PATCH 059/120] ath11k: Handle MSI enablement during rmmod and SSR
When doing "rmmod ath11k_pci", ath11k performs global SOC reset
and MHI reset, where 0 address access is captured by IOMMU. See
log below:
...
[ 133.953860] ath11k_pci 0000:02:00.0: setting mhi state: DEINIT(1)
[ 133.959714] ath11k_pci 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020]
[ 133.973854] ath11k_pci 0000:02:00.0: MHISTATUS 0xff04
[ 133.974095] ath11k_pci 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020]
...
This issue is also observed in SSR process, cause a similar
sequence as above is performed.
Such an invalid access occurs because, during rmmod or SSR, MSI
address is cleared but HW MSI functionality not disabled, thus HW
target is able to raise an MSI transaction with 0 as MSI address.
So it can be fixed by simply disabling MSI before reset. For SSR,
since MSI functionality is still needed after target is brought
back, we need to reenable it.
Also change naming of some interfaces related.

Subject: [PATCH 060/120] ath11k: Change number of TCL rings to one for QCA6390
Some targets, QCA6390 for example, use only one TCL ring, it is better to
initialize only one ring and leave others untouched for such targets.
This is a theoretical fix found during code review, no visible impact.

WMI_CHAN_INFO_DFS flag should be set when configuring a DFS channel
included in scan channel list. Without it, firmware will not send a
probe request frame which is needed in connection to an AP configured
with hidden SSID/network_id. So fix this to allow probe request frames
to be sent in cases where a beacon frame has been seen on the channel
first.

Subject: [PATCH 062/120] ath11k: change return buffer manager for QCA6390
QCA6390 firmware uses HAL_RX_BUF_RBM_SW1_BM, not HAL_RX_BUF_RBM_SW3_BM. This is
needed to fix a case where an A-MSDU has an unexpected LLC/SNAP header in the
first subframe (CVE-2020-24588).

Subject: [PATCH 063/120] ath11k: set correct NL80211_FEATURE_DYNAMIC_SMPS for
WCN6855
Commit 6f4d70308e5e ("ath11k: support SMPS configuration for 6 GHz") changed
"if (ht_cap & WMI_HT_CAP_DYNAMIC_SMPS)" to "if (ht_cap &
WMI_HT_CAP_DYNAMIC_SMPS || ar->supports_6ghz)" which means
NL80211_FEATURE_DYNAMIC_SMPS is enabled for all chips which support 6 GHz.
However, WCN6855 supports 6 GHz but it does not support feature
NL80211_FEATURE_DYNAMIC_SMPS, and this can lead to MU-MIMO test failures for
WCN6855.
Disable NL80211_FEATURE_DYNAMIC_SMPS for WCN6855 since its ht_cap does not
support WMI_HT_CAP_DYNAMIC_SMPS. Enable the feature only on QCN9074 as that's
the only other device supporting 6 GHz band.

boolean so change ath11k_wmi_pdev_set_ps_mode() to use a boolean.

Subject: [PATCH 065/120] ath11k: enable 802.11 power save mode in station mode
To reduce power consumption enable 802.11 power save mode in station mode. This
allows both radio and CPU to sleep more.
Only enable the mode on QCA6390 and WCN6855, it's unknown how other hardware
families support this feature.
To test that power save mode is running run "iw dev wls1 set power_save off",
check there is no NULL Data frame seen by a sniffer. And run "iw dev wls1 set power_save
on" and check there is a NULL Data frame in sniffer.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1

Subject: [PATCH 066/120] ath11k: Send PPDU_STATS_CFG with proper pdev mask to
firmware
HTT_PPDU_STATS_CFG_PDEV_ID bit mask for target FW PPDU stats request message
was set as bit 8 to 15. Bit 8 is reserved for soc stats and pdev id starts from
bit 9. Hence change the bitmask as bit 9 to 15 and fill the proper pdev id in
the request message.
In commit 701e48a43e15 ("ath11k: add packet log support for QCA6390"), both
HTT_PPDU_STATS_CFG_PDEV_ID and pdev_mask were changed, but this pdev_mask
calculation is not valid for platforms which has multiple pdevs with 1 rxdma
per pdev, as this is writing same value(i.e. 2) for all pdevs. Hence fixed it
to consider pdev_idx as well, to make it compatible for both single and multi
pd cases.

Subject: [PATCH 067/120] ath11k: Clear auth flag only for actual association
in security mode
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
any key exchange, so AUTH flag is expected to be set in host.

Subject: [PATCH 068/120] ath11k: fix fw crash due to peer get authorized
before key install
Firmware expects host to authorize the peer after the successful key
install. But host authorize the peer before the key install, this trigger
the firmware assert which leads to Q6 crash. To avoid this Q6 crash, host
should authorize the peer after the key install. So introduce is_authorized
in peer object to identify that peer is authorize or not. When
IEEE80211_STA_CONTROL_PORT flag is unset, peer move to authorize state
before the vdev up. When the same flag is set then peer move to authorize
state after vdev up. So added authorise check in ath11k_bss_assoc() to
handle the earlier state transition case. Also added the WMI authorize
procedure in ath11k_mac_op_sta_state() to handle the non-earlier state
transition case.

Subject: [PATCH 069/120] ath11k: fix error routine when fallback of add
interface fails
When there is an error in add interface process from
ath11k_mac_set_kickout(), the code attempts to handle a
fallback for add_interface. When this fallback succeeds, the
driver returns zero rather than error code. This leads to
success for the non created VAP. In cleanup, driver gets
remove interface callback for the non created VAP and
proceeds to self peer delete request which leads to FW assert.

Subject: [PATCH 070/120] ath11k: avoid unnecessary BH disable lock in STA
kickout event
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.
This was found in code review.

Subject: [PATCH 071/120] ath11k: fix DMA memory free in CE pipe cleanup
In CE pipe cleanup, DMA memory gets freed by the aligned address
(base_addr_owner_space) which is wrong. It needs to be freed
by the address (base_addr_owner_space_unaligned) returned by
dma_alloc. So free the dma memory by the proper address.

Subject: [PATCH 073/120] ath11k: fix firmware crash during channel switch
Currently the updated bandwidth for the peer will be configured
to the firmware after channel switch from the sta_rc_update_wk.
If the updated bandwidth is greater than the configured peer phymode
during the peer assoc may result firmware assert.
For example, initially AP is in HE40 mode and the peer phymode is
configured as MODE_11AX_HE40 during peer assoc. Now user change the
channel width to HE80 then, the peer bandwidth will be updated as
HE80 to the firmware.
This will trigger firmware assert due to peer bandwidth is greater than
the peer phymode.
Fix this issue by sending peer assoc command before setting the updated
peer bandwith to firmware.

memory
tcl_data and reo_dst rings are currently being allocated using
dma_allocate_coherent() which is non cacheable.
Allocating ring memory from cacheable memory area allows cached descriptor
access and prefetch next descriptors to optimize CPU usage during
descriptor processing on NAPI. Based on the hardware param we can enable
or disable this feature for the corresponding platform.

Subject: [PATCH 076/120] ath11k: modify dp_rx desc access wrapper calls inline
In data path, to reduce the CPU cycles spending on descriptor access
wrapper function, changed those functions as static inline.

Subject: [PATCH 077/120] ath11k: avoid additional access to
ath11k_hal_srng_dst_num_free
In ath11k_dp_process_rx(), after processing rx_desc from
ath11k_hal_srng_dst_get_next_entry(), ath11k_hal_srng_dst_num_free()
is accessed everytime because of done flag is not set.
To avoid this additional access to ath11k_hal_srng_dst_num_free(),
increment total_msdu_reaped only when continuation is not set and
update done flag correspondingly.

Subject: [PATCH 078/120] ath11k: avoid active pdev check for each msdu
The Active Pdev and CAC check are done for each msdu in
ath11k_dp_rx_process_received_packets which is a overhead.
To avoid this overhead, collect all msdus in a per mac msdu
list and pass to function.

Subject: [PATCH 079/120] ath11k: remove usage quota while processing rx
packets
The usage of quota variable inside ath11k_dp_rx_process_received_packets()
is redundant. Since we would queue only max packets to the list before
calling this function so it would never exceed quota. Hence removing
usage of quota variable.

Subject: [PATCH 080/120] ath11k: add branch predictors in process_rx
In datapath, add branch predictors where required in the process rx().
This protects high value rx path without having performance overhead.
Also while processing rx packets, the pointer that is returned by
rcu_dereference() is not dereferenced. so it is preferable to use
rcu_access_pointer() here.

to directly fetch the ring number. Hence remove the while loop
and directly get the ring number from tx mask and group id.

Subject: [PATCH 085/120] ath11k: avoid unnecessary lock contention in
tx_completion path
Avoid unnecessary idr_find calls before the idr_remove calls. Because
idr_remove gives the valid ptr if id is valid otherwise return NULL ptr.
So removed the idr_find before idr_remove in tx completion path. Also no
need to disable the bottom half preempt if it is already in the
bottom half context, so modify the spin_lock_bh to spin_lock in the
data tx completion path.

Subject: [PATCH 086/120] ath11k: enable IEEE80211_VHT_EXT_NSS_BW_CAPABLE if
NSS ratio enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When NSS ratio enabled reported by firmware, SUPPORTS_VHT_EXT_NSS_BW
is set in ath11k, meanwhile IEEE80211_VHT_EXT_NSS_BW_CAPABLE also
need to be set, otherwise it is invalid because spec in IEEE Std
802.11™‐2020 as below.
Table 9-273-Supported VHT-MCS and NSS Set subfields, it has subfield
VHT Extended NSS BW Capable, its definition is:
Indicates whether the STA is capable of interpreting the Extended NSS
BW Support subfield of the VHT Capabilities Information field.
dmesg have a message without this patch:
ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag
It means mac80211 will set IEEE80211_VHT_EXT_NSS_BW_CAPABLE if ath11k not
set it in ieee80211_register_hw(). So it is better to set it in ath11k.

Subject: [PATCH 087/120] ath11k: remove return for empty tx bitrate in
mac_op_sta_statistics
Currently in ath11k_mac_op_sta_statistics() there is the following
logic:
if (!arsta->txrate.legacy && !arsta->txrate.nss)
return;
Unfortunately if this condition is true then the function returns without
setting parameters that follow the txrate. To address this issue remove the
return and instead invert the logic to set the txrate logic if
(arsta->txrate.legacy || arsta->txrate.nss).
The same was done also in ath10k in commit 1cd6ba8ae33e ("ath10k: remove return
for NL80211_STA_INFO_TX_BITRATE").

When station connect to AP, the wmi command sequence is:

and sequence of station disconnect fo AP is:
peer_delete->vdev_down->vdev_stop
The sequence of disconnect is not opposite of connect, it caused firmware
crash when it handle wmi vdev stop cmd when the AP is support TWT of
802.11 ax, because firmware need access the bss peer for vdev stop cmd.

The opposite sequence of disconnect should be:

This patch change the sequence of disconnect for station as above
opposite sequence for QCA6390, firmware not crash again with this patch.

Subject: [PATCH 091/120] ath11k: send proper txpower and maxregpower values to
firmware
Set proper values for max_regpower, max_power, max_antenna_gain as it
is because firmware will convert power values to 0.5dbm steps by
multiplying it with 2.
If txpower is not set, it will lead to cca stuck resulting in latency
issues for QCN9074.

Subject: [PATCH 092/120] ath11k: Increment pending_mgmt_tx count before tx
send invoke
There is a race condition whereby the tx completion handler can be invoked
before the 'num_pending_mgmt_tx" count is incremented. If that occurs, we
could get warning trace indicating that 'num_pending_mgmt_tx' is 0 (because
it was not yet incremented). Ideally, this trace should be seen only if
mgmt tx has not happened but tx completion is received, and it is not
expected in this race condition.

Subject: [PATCH 093/120] ath11k: Fix ETSI regd with weather radar overlap
Some ETSI countries have a small overlap in the wireless-regdb with an ETSI
channel (5590-5650). A good example is Australia:
country AU: DFS-ETSI
(2400 - 2483.5 @ 40), (36)
(5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (20), NO-OUTDOOR, AUTO-BW, DFS
(5470 - 5600 @ 80), (27), DFS
(5650 - 5730 @ 80), (27), DFS
(5730 - 5850 @ 80), (36)
(57000 - 66000 @ 2160), (43), NO-OUTDOOR
If the firmware (or the BDF) is shipped with these rules then there is only
a 10 MHz overlap with the weather radar:
* below: 5470 - 5590
* weather radar: 5590 - 5600
* above: (none for the rule "5470 - 5600 @ 80")
There are several wrong assumption in the ath11k code:
* there is always a valid range below the weather radar
(actually: there could be no range below the weather radar range OR range
could be smaller than 20 MHz)
* intersected range in the weather radar range is valid
(actually: the range could be smaller than 20 MHz)
* range above weather radar is either empty or valid
(actually: the range could be smaller than 20 MHz)
These wrong assumption will lead in this example to a rule
(5590 - 5600 @ 20), (N/A, 27), (600000 ms), DFS, AUTO-BW
which is invalid according to is_valid_reg_rule() because the freq_diff is
only 10 MHz but the max_bandwidth is set to 20 MHz. Which results in a
rejection like:
WARNING: at backports-20210222_001-4.4.60-b157d2276/net/wireless/reg.c:3984
[...]

ath11k c000000.wifi: failed to perform regd update : -22
Invalid regulatory domain detected
To avoid this, the algorithm has to be changed slightly. Instead of
splitting a rule which overlaps with the weather radar range into 3 pieces
and accepting the first two parts blindly, it must actually be checked for
each piece whether it is a valid range. And only if it is valid, add it to
the output array.
When these checks are in place, the processed rules for AU would end up as
country AU: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 36), (N/A)
(5150 - 5250 @ 80), (6, 23), (N/A), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (6, 20), (0 ms), NO-OUTDOOR, DFS, AUTO-BW
(5470 - 5590 @ 80), (6, 27), (0 ms), DFS, AUTO-BW
(5650 - 5730 @ 80), (6, 27), (0 ms), DFS, AUTO-BW
(5730 - 5850 @ 80), (6, 36), (N/A), AUTO-BW
and will be accepted by the wireless regulatory code.

Subject: [PATCH 094/120] ath11k: Disabling credit flow for WMI path
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.

Subject: [PATCH 095/120] ath11k: use cache line aligned buffers for dbring
The DMA buffers of dbring which is used for spectral/cfr
starts at certain offset from original kmalloc() returned buffer.
This is not cache line aligned.
And also driver tries to access the data that is immediately before
this offset address (i.e. buff->paddr) after doing dma map.
This will cause cache line sharing issues and data corruption,
if CPU happen to write back cache after HW has dma'ed the data.
Fix this by mapping a cache line aligned buffer to dma.
Tested on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1

Subject: [PATCH 096/120] ath11k: Add missing qmi_txn_cancel()
Currently many functions do not follow this guidance when
qmi_send_request() fails, therefore add missing
qmi_txn_cancel() in the qmi_send_request() error path.
Also remove initialization on 'struct qmi_txn'
since qmi_tx_init() performs all necessary initialization.

Subject: [PATCH 098/120] ath11k: Fix crash caused by uninitialized TX ring
Commit 31582373a4a8 ("ath11k: Change number of TCL rings to one for
QCA6390") avoids initializing the other entries of dp->tx_ring cause
the corresponding TX rings on QCA6390/WCN6855 are not used, but leaves
those ring masks in ath11k_hw_ring_mask_qca6390.tx unchanged. Normally
this is OK because we will only get interrupts from the first TX ring
on these chips and thus only the first entry of dp->tx_ring is involved.
In case of one MSI vector, all DP rings share the same IRQ. For each
interrupt, all rings have to be checked, which means the other entries
of dp->tx_ring are involved. However since they are not initialized,
system crashes.
Fix this issue by simply removing those ring masks.

Subject: [PATCH 099/120] ath11k: add string type to search board data in
board-2.bin for WCN6855
Currently ath11k only support string type with bus, chip id and board id
such as "bus=ahb,qmi-chip-id=1,qmi-board-id=4" for ahb bus chip and
"bus=pci,qmi-chip-id=0,qmi-board-id=255" for PCIe bus chip in
board-2.bin. For WCN6855, it is not enough to distinguish all different
chips.
This is to add a new string type which include bus, chip id, board id,
vendor, device, subsystem-vendor and subsystem-device for WCN6855.
ath11k will first load board-2.bin and search in it for the board data
with the above parameters, if matched one board data, then download it

Subject: [PATCH 100/120] ath11k: add support for BSS color change
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.

Subject: [PATCH 101/120] ath11k: clear the keys properly via DISABLE_KEY
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
to be still encrypted without vdev restart.
Set the proper key_len for DISABLE_KEY cmd to clear the keys in
firmware.

Subject: [PATCH 102/120] ath11k: reset RSN/WPA present state for open BSS
The ath11k driver is caching the information about RSN/WPA IE in the
configured beacon template. The cached information is used during
associations to figure out whether 4-way PKT/2-way GTK peer flags need to
be set or not.
But the code never cleared the state when no such IE was found. This can
for example happen when moving from an WPA/RSN to an open setup. The
(seemingly connected) peer was then not able to communicate over the
link because the firmware assumed a different (encryption enabled) state
for the peer.

Subject: [PATCH 103/120] ath11k: add hw_param for wakeup_mhi
Wakeup mhi is needed before pci_read/write only for QCA6390 and WCN6855. Since
wakeup & release mhi is enabled for all hardwares, below mhi assert is seen in
QCN9074 when doing 'rmmod ath11k_pci':

Subject: [PATCH 104/120] ath11k: get msi_data again after request_irq is
called
The reservation mode of interrupts in kernel assigns a dummy vector
when the interrupt is allocated and assigns a real vector when the
request_irq is called. The reservation mode helps to ease vector
pressure when devices with a large amount of queues/interrupts
are initialized, but only a minimal subset of those queues/interrupts
is actually used.
So on reservation mode, the msi_data may change after request_irq
is called, so ath11k reads msi_data again after request_irq is called,
and then the correct msi_data is programmed into QCA6390 hardware
components. Without this change, spurious interrupt occurs in case of
one MSI vector. When VT-d in BIOS is enabled and ath11k can get 32 MSI
vectors, ath11k always get the same msi_data before and after request_irq,
that's why this change is only required when one MSI vector is to be
supported.

Subject: [PATCH 105/120] ath11k: add CE and ext IRQ flag to indicate
irq_handler
This change adds two flags to indicate whether IRQ handler for CE
and DP can be called. This is because in one MSI vector case,
interrupt is not disabled in hif_stop and hif_irq_disable. Otherwise,
MHI interrupt is disabled too.

From ac6e73483f7b4b5bde23b14fc3aaafc8341ae0c7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 108/120] ath11k: add support one MSI vector
On some platforms it's not possible to allocate 32 MSI vectors for various
reasons, be it kernel configuration, VT-d disabled, buggy BIOS etc. So
ath11k was not able to use QCA6390 PCI devices on those platforms. Add
support for one MSI vector to solve that.
In case of one MSI vector, interrupt migration needs to be disabled. This
is because when interrupt migration happens, the msi_data may change.
However, msi_data is already programmed to rings during initial phase and
ath11k has no way to know that msi_data is changed during run time and
reprogram again.
In case of one MSI vector, MHI subsystem should not use IRQF_NO_SUSPEND
as QCA6390 doesn't set this flag too. Ath11k doesn't need to leave
IRQ enabled in suspend state.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
