6707ba0105 ath10k: avoid possible string overflow
The way that 'strncat' is used here raised a warning in gcc-8:

drivers/net/wireless/ath/ath10k/wmi.c: In function 'ath10k_wmi_tpc_stats_final_disp_tables':
drivers/net/wireless/ath/ath10k/wmi.c:4649:4: error: 'strncat' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]

Effectively, this is simply a strcat() but the use of strncat() suggests
some form of overflow check. Regardless of whether this might actually
overflow, using strlcat() instead of strncat() avoids the warning and
makes the code more robust.

1b3fdb50f8 ath10k: fix vdev stats for 10.4 firmware
Currently vdev stats displayed in fw_stats are applicable
only for TLV based firmware and fix it for 10.4 firmware
as of now. The vdev stats in 10.4 firmware is split into two
parts (vdev_stats, vdev_stats_extended). The actual stats
are captured only in extended vdev stats. In order to enable
vdev stats, appropriate feature bit will be set on extended
resource config. As FTM related counters are available only on
newer 10.4 based firmware, these counters will be displayed
only on valid data.

606204bb86 ath10k: suppress "Unknown eventid: 36925" warnings
FW has Smart Logging feature enabled by default for detecting failures
and processing FATAL_CONDITION_EVENTID (36925 - 0x903D) back to host.

Since ath10k doesn't implement the Smart Logging and FATAL CONDITION
EVENT processing yet, suppressing the unknown event ID warning by moving
this under ATH10K_DBG_WMI.

Simulated the same issue by having associated STA powered off when
ping flood was running from AP backbone. This triggerd STA KICKOUT

The skb may be freed in tx completion context before
trace_ath10k_wmi_cmd is called. This can be easily captured when
KASAN(Kernel Address Sanitizer) is enabled. The fix is to move

WMI interface for all the firmwares(except QCA6174) does not include the
type of peer(default/bss/tdls) requested during peer creation, therefore
target creates a default peer.

TDLS implementation on 10.4 firmware requires host to configure the
peer type(tdls) for TDLS peers. This patch adds peer type parameter to the
existing WMI interface for peer creation to accommodate this requirement.

Tested this change on QCA9888(10.4-3.5.1-00018) and QCA988x(10.2.4.70.9-2)

cc914a5500 ath10k: configure rxnss_override for QCA9984
QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz.

First, report this to user-space by setting the max-tx-speed
and max-rx-speed vht capabilities.

Second, if the peer rx-speed is configured, and if we
are in 160 or 80+80 mode, and the peer rx-speed matches
the max speed for 2x2 or 1x1 at 160Mhz (long guard interval),
then use that info to set the peer_bw_rxnss_override appropriately.

Without this, a 9984 firmware will not use 2x2 ratesets when
transmitting to peer (it will be stuck at 1x1), because
the firmware would not have configured the rxnss_override.

79e6882158 ath10k: go back to using dma_alloc_coherent() for firmware scratch memory
This reverts commit b057886524be ("ath10k: do not use coherent memory for
allocated device memory chunks") in 2015 which converted this allocation from
dma_map_coherent() to kzalloc() / dma_map_single().

The current problem manifests when using later model NICs with larger
(>700KiB) scratch spaces in memory.  Although the kzalloc call
succeeds, the software IOMMU TLB code (via dma_map_single()) panics
because it can't find 700KiB of linear physmem bounce buffers for DMA.
Now, this is a bit of a silly failure mode for the dma map API,
but it's what we currently have to play with.

In these cases, doing kzalloc() works fine, but the dma_map_single()
call fails.

After chatting with Linus briefly about this, it indeed should be
using dma_alloc_coherent() for doing larger device memory allocation
that requires some kind of physical address mapping.

You're not supposed to be using kzalloc and dma_map_* calls for
large memory regions, and I'm guessing not for long-held mappings
either.  Typically dma mappings should be temporary for DMA,
not long held like these.

Now, since hopefully the major annoying underlying problem has also been
addressed (ie, ath10k is no longer tears down all of these allocations
and reallocates them every time the vdevs are brought down) fragmentation
should stop being such a touchy issue.  If it is though, using
dma_alloc_coherent() use gets us access to the CMB APIs too relatively
easily and ideally we would be allocating memory early in boot for
exactly these reasons.

a28f6f27a8 ath10k: fix fetching channel during potential radar detection
Fetch target operating channel during potential radar detection when
the interface is just brought up, but no channel is assigned from
userspace. In this scenario rx_channel may not be having a valid pointer
hence fetch the target operating channel to avoid warnings as below
which can be triggered by the commands with DFS testing over longer run

comamnds:
iw wlan1 set type mesh
ifconfig wlan1 up (valid tgt_oper_chan only)
iw wlan1 cac trigger freq 5260 HT20 (valid rx_channel, tgt_oper_chan)
iw wlan1 cac trigger freq 5280 HT20
iw wlan1 cac trigger freq 5300 HT20

Once the CAC expires, current channel context will be removed and
we are only left with the fallback option of using 'target operating
channel'

523f6701db ath10k: update available channel list for 5G radio
If a 5 GHz radio is calibrated for operation in both
the low band (channels 36 to 64) and high band(channels 100 to 169),
hardware allows operations in all the listed channels. However,
if the chip has been calibrated only for the low/high band and
a high/low band channel is configured, due to lack of calibration
there will be potentially invalid signal on those non calibrated channels.
To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for
those non calibrated channels by using low_5ghz_chan and high_5ghz_chan
values which we get from target through wmi service ready event.

Driver initialized flags are getting re initialized in handle_channel
in cfg80211. So calling the function to disable the non supported channel
from reg_notifier().

f6f64cfb96 ath10k: remove set/get_tsf ieee80211_ops
Neither of these did the right thing:

- get_tsf just returned 0
- set_tsf assumed a simple offset was applied against
  get_tsf(), which works, except in the case of
  calculating TSF from rx_mactime (actual TSF).

Just remove them for now. We can reimplement set_tsf in
terms of TSF increment/decrement in the future if get_tsf
is ever supported by FW.

973324fff1 ath10k: implement offset_tsf ieee80211_op
Current set_tsf is implemented in terms of TSF_INCREMENT
only. Instead support new WMI command TSF_DECREMENT and
export these through offset_tsf. Advantage is we get
more accurate TSF adjustments, and don't calculate wrong
offset in case absolute TSF was calculated from rx_mactime
(actual TSF).

The new WMI command is available in firmware
10.4-3.2.1-00033 for QCA4019 chips. Old drivers on new
firmware or vice versa shouldn't  be a problem since
get/set tsf logic was already broken.

ebee76f7fa ath10k: allow setting coverage class
Unfortunately ath10k does not generally allow modifying the coverage class
with the stock firmware and Qualcomm has so far refused to implement this
feature so that it can be properly supported in ath10k. If we however know
the registers that need to be modified for proper operation with a higher
coverage class, then we can do these modifications from the driver.

This is a hack and might cause subtle problems but as it's not enabled by
default (only when user space changes the coverage class explicitly) it should
not cause new problems for existing setups. But still this should be considered
as an experimental feature and used with caution.

This patch implements the support for first generation cards (QCA9880, QCA9887
and so on) which are based on a core that is similar to ath9k. The registers
are modified in place and need to be re-written every time the firmware sets
them. To achieve this the register status is verified after certain WMI events
from the firmware.

The coverage class may not be modified temporarily right after the card
re-initializes the registers. This is for example the case during scanning.

Thanks to Sebastian Gottschall <s.gottschall@dd-wrt.com> for initially
working on a userspace support for this. This patch wouldn't have been
possible without this documentation.

97f2645f35 tree-wide: replace config_enabled() with IS_ENABLED()
The use of config_enabled() against config options is ambiguous.  In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED().  Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc.  makes the intention
clearer.

This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.

I noticed two cases where config_enabled() is used against a tristate
option:

 - config_enabled(CONFIG_HWMON)
  [ drivers/net/wireless/ath/ath10k/thermal.c ]

 - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
  [ drivers/gpu/drm/gma500/opregion.c ]

I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

4a49ae94a4 ath10k: fix 10.4 extended peer stats update
10.4 'extended peer stats' will be not be appended with normal peer stats
data and they shall be coming in separate chunks. Fix this by maintaining
a separate linked list 'extender peer stats' for 10.4 and update
rx_duration for per station statistics. Also parse through beacon filter
(if enabled), to make sure we parse the extended peer stats properly.
This issue was exposed when more than one client is connected and
extended peer stats for 10.4 is enabled

The order for the stats is as below
S - standard peer stats, E- extended peer stats, B - beacon filter stats

{S1, S2, S3..} -> {B1, B2, B3..}(if available) -> {E1, E2, E3..}

Fixes: f9575793d44c ("ath10k: enable parsing per station rx duration for 10.4")

a66cd733a7 ath10k: fix potential null dereference bugs
Smatch warns about a number of cases in ath10k where a pointer is
null-checked after it has already been dereferenced, in code involving
ath10k private virtual interface pointers.

Fix these by making the dereference happen later.

Addresses the following smatch warnings:

drivers/net/wireless/ath/ath10k/mac.c:3651 ath10k_mac_txq_init() warn: variable dereferenced before check 'txq' (see line 3649)

36bd39bb0a ath10k: suppress warnings when getting wmi peer_rate_code_list event
In 10.4, fw sends WMI PEER_RATECODE_LIST_EVENTID after successful
peer_assoc cmd. As of now this event is not of much use and not
implemented. Change the debug level and messsage as appropriate
to suppress "Unknown eventid: 36898".

fa7937e3d5 ath10k: update bss channel survey information
During hw scan, firmware sends two channel information events (pre-
complete, complete) to host for each channel change. The snap shot of cycle
counters (rx_clear and total) between these two events are given for
survey dump. In order to get latest survey statistics of all channels, a
scan request has to be issued. In general, an AP DUT is brought up, it
won't leave BSS channel except few cases like overlapping bss or radar
detection. So survey statistics of bss channel is always referring to
older data that are collected before starting AP (either ACS/OBSS scan).

To collect latest survey information from target, firmware provides WMI
interface to read cycle counters from hardware. For each survey dump
request, BSS channel cycle counters are read and cleared in hardware.
This makes sure that behavior is in align with ath9k survey report.
So survey dump always gives snap shot of cycle counters b/w two survey
requests.
