f9fff67d2d wifi: ath11k: Fix SKB corruption in REO destination ring
While running traffics for a long time, randomly an RX descriptor
filled with value "0" from REO destination ring is received.
This descriptor which is invalid causes the wrong SKB (SKB stored in
the IDR lookup with buffer id "0") to be fetched which in turn
causes SKB memory corruption issue and the same leads to crash
after some time.

Changed the start id for idr allocation to "1" and the buffer id "0"
is reserved for error validation. Introduced Sanity check to validate
the descriptor, before processing the SKB.

Crash Signature :

ieee80211_tx_status() treats packets in 802.11 frame format and
tries to extract sta address from packet header. When tx encap

93a91f40c2 wifi: ath11k: fix double free of peer rx_tid during reo cmd failure
Peer rx_tid is locally copied thrice during peer_rx_tid_cleanup to
send REO_CMD_UPDATE_RX_QUEUE followed by REO_CMD_FLUSH_CACHE to flush
all aged REO descriptors from HW cache.

When sending REO_CMD_FLUSH_CACHE fails, we do dma unmap of already
mapped rx_tid->vaddr and free it. This is not checked during
reo_cmd_list_cleanup() and dp_reo_cmd_free() before trying to free and
unmap again.

Fix this by setting rx_tid->vaddr NULL in rx tid delete and also
wherever freeing it to check in reo_cmd_list_cleanup() and
reo_cmd_free() before trying to free again.

a06bfb3c9f wifi: ath11k: Ignore frags from uninitialized peer in dp.
When max virtual ap interfaces are configured in all the bands with
ACS and hostapd restart is done every 60s, a crash is observed at
random times.
In this certain scenario, a fragmented packet is received for
self peer, for which rx_tid and rx_frags are not initialized in
datapath. While handling this fragment, crash is observed as the
rx_frag list is uninitialised and when we walk in
ath11k_dp_rx_h_sort_frags, skb null leads to exception.

To address this, before processing received fragments we check
dp_setup_done flag is set to ensure that peer has completed its
dp peer setup for fragment queue, else ignore processing the
fragments.

e89a51aedf wifi: ath11k: Send 11d scan start before WMI_START_SCAN_CMDID
Firmwares advertising the support of triggering 11d algorithm on the
scan results of a regular scan expects driver to send
WMI_11D_SCAN_START_CMDID before sending WMI_START_SCAN_CMDID.
Triggering 11d algorithm on the scan results of a normal scan helps
in completely avoiding a separate 11d scan for determining regdomain.
This indirectly helps in speeding up connections on station
interfaces on the chipsets supporting 11D scan.

To enable this feature, send WMI_11D_SCAN_START_CMDID just before
sending WMI_START_SCAN_CMDID if the firmware advertises
WMI_TLV_SERVICE_SUPPORT_11D_FOR_HOST_SCAN service flag.

WCN6750 & WCN6855 supports this feature.

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.

031ffa6c2c wifi: ath11k: fix rssi station dump not updated in QCN9074
In QCN9074, station dump signal values display default value which
is -95 dbm, since there is firmware header change for HAL_RX_MPDU_START
between QCN9074 and IPQ8074 which cause wrong peer_id fetch from msdu.
Fix this by updating hal_rx_mpdu_info with corresponding QCN9074 tlv
format.

8b4d2f080a wifi: ath11k: Optimize 6 GHz scan time
Currently, time taken to scan all supported channels on WCN6750
is ~8 seconds and connection time is almost 10 seconds. WCN6750
supports three Wi-Fi bands (i.e., 2.4/5/6 GHz) and the numbers of
channels for scan come around ~100 channels (default case).
Since the chip doesn't have support for DBS (Dual Band Simultaneous),
scans cannot be parallelized resulting in longer scan times.

Among the 100 odd channels, ~60 channels are in 6 GHz band. Therefore,
optimizing the scan for 6 GHz channels will bring down the overall
scan time.

WCN6750 firmware has support to scan a 6 GHz channel based on co-located
AP information i.e., RNR IE which is found in the legacy 2.4/5 GHz scan
results. When a scan request with all supported channel list is enqueued
to the firmware, then based on WMI_SCAN_CHAN_FLAG_SCAN_ONLY_IF_RNR_FOUND
scan channel flag, firmware will scan only those 6 GHz channels for which
RNR IEs are found in the legacy scan results.

In the proposed design, based on NL80211_SCAN_FLAG_COLOCATED_6GHZ scan
flag, driver will set the WMI_SCAN_CHAN_FLAG_SCAN_ONLY_IF_RNR_FOUND flag
for non-PSC channels. Since there is high probability to find 6 GHz APs
on PSC channels, these channels are always scanned. Only non-PSC channels
are selectively scanned based on cached RNR information from the legacy
scan results.

If NL80211_SCAN_FLAG_COLOCATED_6GHZ is not set in the scan flags,
then scan will happen on all supported channels (default behavior).

With these optimizations, scan time is improved by 1.5-1.8 seconds on
WCN6750. Similar savings have been observed on WCN6855.

cf5fa3ca05 wifi: ath11k: reduce the MHI timeout to 20s
Currently ath11k breaks after hibernation, the reason being that ath11k expects
that the wireless device will have power during suspend and the firmware will
continue running. But of course during hibernation the power from the device is
cut off and firmware is not running when resuming, so ath11k will fail.

(The reason why ath11k needs the firmware running is the interaction between
mac80211 and MHI stack, it's a long story and more info in the bugzilla report.)

In SUSE kernels the watchdog timeout is reduced from the default 120 to 60 seconds:

CONFIG_DPM_WATCHDOG_TIMEOUT=60

But as the ath11k MHI timeout is 90 seconds the kernel will crash before will
ath11k will recover in resume callback. To avoid the crash reduce the MHI
timeout to just 20 seconds.

68e93ac5a3 wifi: ath11k: fix BUFFER_DONE read on monitor ring rx buffer
Perform dma_sync_single_for_cpu() on monitor ring rx buffer before
reading BUFFER_DONE tag and do dma_unmap_single() only after device
had set BUFFER_DONE tag to the buffer.

Also when BUFFER_DONE tag is not set, allow the buffer to get read
next time without freeing skb.

This helps to fix AP+Monitor VAP with flood traffic scenario to see
monitor ring rx buffer overrun missing BUFFER_DONE tag to be set.

Also remove redundant rx dma buf free performed on DP
rx_mon_status_refill_ring.

5a78ac33e3 wifi: ath11k: fix deinitialization of firmware resources
Currently, in ath11k_ahb_fw_resources_init(), iommu domain
mapping is done only for the chipsets having fixed firmware
memory. Also, for such chipsets, mapping is done only if it
does not have TrustZone support.

During deinitialization, only if TrustZone support is not there,
iommu is unmapped back. However, for non fixed firmware memory
chipsets, TrustZone support is not there and this makes the
condition check to true and it tries to unmap the memory which
was not mapped during initialization.

This leads to the following trace -

This can be reproduced by probing an AHB chipset which is not
having a fixed memory region. During reboot (or rmmod) trace
can be seen.

Fix this issue by adding a condition check on firmware fixed memory
hw_param as done in the counter initialization function.

 	  blocking and atomic variants so far, but that was problematic

 	  So Jason consolidated this back into single functions that
 	  take a GFP parameter. This has the potential to cause
 	  conflicts with other trees, as they introduce new call-sites
 	  for the changed functions. I offered them to pull in the

 	  sure everyone did that. The conflicts this caused with
 	  upstream up to v6.2-rc8 are resolved in the final merge
 	  commit.

7c15430822 wifi: ath11k: allow system suspend to survive ath11k
When ath11k runs into internal errors upon suspend,
it returns an error code to pci_pm_suspend, which
aborts the entire system suspend.

The driver should not abort system suspend, but should
keep its internal errors to itself, and allow the system
to suspend.  Otherwise, a user can suspend a laptop
by closing the lid and sealing it into a case, assuming
that is will suspend, rather than heating up and draining
the battery when in transit.

In practice, the ath11k device seems to have plenty of transient
errors, and subsequent suspend cycles after this failure
often succeed.

f117276638 wifi: ath11k: Use platform_get_irq() to get the interrupt
As of commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ
resource from DT core"), we need to use platform_get_irq() instead of
platform_get_resource() to get our IRQs because
platform_get_resource() simply won't get them anymore.

This was already fixed in several other Atheros WiFi drivers,
apparently in response to Zeal Robot reports. An example of another
fix is commit 9503a1fc123d ("ath9k: Use platform_get_irq() to get the
interrupt"). ath11k seems to have been missed in this effort, though.

Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based
hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ,
i)" was failing even for i=0.

53a998c4d7 wifi: ath11k: fix ce memory mapping for ahb devices
Currently ath11k_ahb module is not loaded successfully and the wifi
interface is not created. Kernel trace is seen while loading the
ath11k_ahb module. The issue is seen in all ath11k AHB devices except
in IPQ5018.

This happens because in ath11k_ahb_probe(), ab->mem_ce is initialized
with the value of ab->mem. However, at this instant ab->mem is not
yet set.

Later, during write to a particular memory via ath11k_ahb_write32()
this ab->mem_ce is used with particular offset. Since ab->mem_ce is
not set properly this possibly leads to memory conflict to handle
kernel paging request and the below trace is seen.

However, for the device IPQ5018 ath11k_hw_params .ce_remap is
defined. This parameter is used to recalculate ab->mem_ce and hence,
this issue is not seen in IPQ5018.

Hence, fix this by initializing ab->mem_ce after ab->mem is set.
ab->mem is set inside the ath11k_ahb_setup_resources() therefore
initialize ab->mem_ce after ath11k_ahb_setup_resources().

a27c6a5853 wifi: ath11k: Add support to configure FTM responder role
Fine Timing Measurement(FTM) support is used to measure round trip
time between two nodes.

Enable FTM responder feature using hw_params on supported device.
Since FTM functionality is offloaded to firmware, adding the
interface allows user space to enable or disable FTM responder.
Also add support for advertising the same in extended capabilities.

QCA6390, WCN6855 and WCN6750 do not support this feature.

323d91d468 wifi: ath11k: debugfs: fix to work with multiple PCI devices
ath11k fails to load if there are multiple ath11k PCI devices with same name:

 ath11k_pci 0000:01:00.0: Hardware name qcn9074 hw1.0
 debugfs: Directory 'ath11k' with parent '/' already present!
 ath11k_pci 0000:01:00.0: failed to create ath11k debugfs
 ath11k_pci 0000:01:00.0: failed to create soc core: -17
 ath11k_pci 0000:01:00.0: failed to init core: -17
 ath11k_pci: probe of 0000:01:00.0 failed with error -17

Fix this by creating a directory for each ath11k device using schema
<bus>-<devname>, for example "pci-0000:06:00.0". This directory created under
the top-level ath11k directory, for example /sys/kernel/debug/ath11k.

The reference to the toplevel ath11k directory is not stored anymore within ath11k, instead
it's retrieved using debugfs_lookup(). If the directory does not exist it will
be created. After the last directory from the ath11k directory is removed, for
example when doing rmmod ath11k, the empty ath11k directory is left in place,
it's a minor cosmetic issue anyway.

Here's an example hierarchy with one WCN6855:

ath11k
`-- pci-0000:06:00.0
    |-- mac0
    |   |-- dfs_block_radar_events
    |   |-- dfs_simulate_radar
    |   |-- ext_rx_stats
    |   |-- ext_tx_stats
    |   |-- fw_dbglog_config
    |   |-- fw_stats
    |   |   |-- beacon_stats
    |   |   |-- pdev_stats
    |   |   `-- vdev_stats
    |   |-- htt_stats
    |   |-- htt_stats_reset
    |   |-- htt_stats_type
    |   `-- pktlog_filter
    |-- simulate_fw_crash
    `-- soc_dp_stats

I didn't have a test setup where I could connect multiple ath11k devices to the
same the host, so I have only tested this with one device.
