Ashok Raj Nagarajan e4fd726f21 ath10k: fix sending frame in management path in push txq logic
In the wake tx queue path, we are not checking if the frame to be sent
takes management path or not. For eg. QOS null func frame coming here will
take the management path. Since we are not incrementing the descriptor
counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is
possible to see negative values.

When the above counter reaches a negative value, we will not be sending a
probe response out.

    if (is_presp &&
	ar->hw_params.max_probe_resp_desc_thres < htt->num_pending_mgmt_tx)

For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against
num_pending_mgmt_tx (int) and the above condtions comes true if the counter
is negative and we drop the probe response.

To avoid this, check on the wake tx queue path as well for the tx path of
the frame and increment the appropriate counters

Rajkumar Manoharan 83e164b767 ath10k: improve wake_tx_queue ops performance
txqs_lock is interfering with wake_tx_queue submitting more frames.
so queues don't get filled in and don't keep firmware/hardware busy
enough. This change helps to reduce the txqs_lock contention and
wake_tx_queue() blockage to being possible in txrx_unref().

To reduce turn around time of wake_tx_queue ops and to maintain fairness
among all txqs, the callback is updated to push first txq alone from
pending list for every wake_tx_queue call. Remaining txqs will be
processed later upon tx completion.

Below improvements are observed in push-only mode and validated on
IPQ4019 platform. With this change, in AP mode ~10Mbps increase is
observed in downlink (AP -> STA) traffic and approx. 5-10% of CPU
usage is reduced.

Major improvement is observed in 1-hop Mesh mode topology in 11ACVHT80.
Compared to Infra mode, CPU overhead is higher in Mesh mode due to path
lookup and no fast-xmit support. So reducing spin lock contention is
helping in Mesh.

Recent commit 46f6b06050 ("mac80211: Encrypt "Group addressed privacy" action
frames") encrypts group privacy action frames. But qca99x0 family chipset
delivers broadcast/multicast management frames as encrypted and it should be
decrypted by mac80211. Setting RX_FLAG_DECRYPTED stats for those frames is
breaking mesh connection establishment.

The extraction is done before wiphy structure is

Lior David 5ffae43208 wil6210: fix protection of wil->scan_request
Currently the places that check wil->scan_request and
call cfg80211_scan_done are not consistently protected,
so there is a risk that cfg80211_scan_done will be called
with NULL scan_request, causing a kernel crash.
Fix this by using p2p_wdev_mutex in few other places
that access scan_request. This makes sense since
scan_request may point to p2p_wdev, and it is not worth
the extra complexity of adding a new mutex.

Michal Kazior 47b1848d9f ath10k: fix spurious tx/rx during boot
HW Rx filters and masks are not configured
properly by firmware during boot sequences. The
MAC_PCU_ADDR1 is set to 0s instead of 1s which
allows the HW to ACK any frame that passes through
MAC_PCU_RX_FILTER. The MAC_PCU_RX_FILTER itself
is misconfigured on boot as well.

The combination of these bugs ended up with the
following manifestations:
 - "no channel configured; ignoring frame(s)!"
   warnings in the driver
 - spurious ACKs (transmission) on the air during
   firmware bootup sequences

The former was a long standing and known bug
originally though mostly harmless.

However Marek recently discovered that this
problem also involves ACKing *all* frames the HW
receives (including beacons ;). Such frames
are delivered to host and generate the former
warning as well.

This could be a problem with regulatory compliance
in some rare cases (e.g. Taiwan which forbids
transmissions on channel 36 which is the default
bootup channel on 5Ghz band cards). The good news
is that it'd require someone else to violate
regulatory first to coerce our device to generate
and transmit an ACK.

The problem could be reproduced in a rather busy
environment that has a lot of APs. The likelihood
could be increased by injecting an msleep() of
5000 or longer immediately after
ath10k_htt_setup() in ath10k_core_start().

The reason why the former warnings were only
showing up seldom is because the device was either
quickly reset again (i.e. during firmware probing)
or wmi vdev was created (which fixes hw and fw
states).

It is technically possible for host driver to
override adequate hw registers however this can't
work reliably because the bug root cause lies in
incorrect firmware state on boot (internal
structure used to program MAC_PCU_ADDR1 is not
properly initialized) and only vdev create/delete
events can fix it. This is why the patch takes
dummy vdev approach.

This could be fixed in firmware as well but having
this fixed in driver is more robust, most notably
when thinking of users of older firmware such as
999.999.0.636.

Lior David 2690c4c0e8 wil6210: fix wiphy registration sequence
Currently wiphy structure is initialized and registered
in wil_if_alloc, before some information is available such
as MAC address and capabilities. As a result there is a
small chance user space will get incorrect information
from calls such as NL80211_CMD_GET_WIPHY.
Fix this by seperating the registration and moving it
to wil_if_add which is executed later, after all
relevant information is known.

Masahiro Yamada 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.

When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.

datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.

to the Ethernet frame header. datap->h_source parameter is now really
pointing to the source ethernet address and the authentication process
can continue.

Benjamin Berg cfda2d8e23 ath9k: Fix beacon configuration for addition/removal of interfaces
This patch fixes some issues with interface reconfiguration. It could
for example happen that an AP interface in beacon slot 0 was removed
leaving an IBSS station in one of the other slots. When this happens
the driver never sends out the beacon as it only tries to send a beacon
from slot 0.

Appart from that the tracking of required changes to the beacon config is
relatively complicated and prone to errors.

The approach taken here is to solve reconfiguration issues is to
reconfigure the beacons when any interface changes. This means that
the complexity of deciding whether an interface change may modify the
beacon configuration is gone. It also means that the beacon config will
be reliably updated when an interface is removed.

The issue that a single non-AP interface might not be in beacon
slot 0 and wouldn't be send out is solved by moving it into the
first slot. The TSF value in hardware is adjusted accordingly so
that the timestamp of the beacons stay consistent.

Beacons were not send out at (timestamp % beacon_time == 0) for interfaces
other than the primary one. To send out beacons with the correct timestamp
according to 10.1.3.2 of the 802.11 standard the tsf_adjustment has to be
set to the negative time difference instead of positive. This way the
later beacons get corrected to have a lower (and similar) timestamp with

Ashok Raj Nagarajan 34293f7558 ath10k: simplify pktlog htt event processing
It is expected that all pktlog events for 10.4 firmware based solutions
should come through CE8 where as in case of 10.2 firmware based solutions,
it should come through one of the HTT events (HTT_T2H_MSG_TYPE_PKTLOG).

But from experiments with 10.4 based solutions, it is observed that pktlog
event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event.
Currently, we always parse with 10.2 pktlog header which will lead to
pktlog decoding issues (payload length mismatch exceptions)

For trace points, it is required to provide only the payload size. So
fixing this by simplifying the payload size calculation without the use of
ath10k pktlog headers.

While there, remove the unused ath10k pktlog headers.

Avraham Stern 1d76250bd3 nl80211: support beacon report scanning
Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.

In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.

Supporting beacon report is required for Multi Band Operation (MBO).

Mohammed Shafi Shajakhan 569fba2cbb ath10k: remove unneccessary WARN_ON_ONCE in rx during ACS
The below warning message seems to hit occasionally with the following
combination (IPQ4019 + ACS scan) where we receive packets as a self peer
when hostapd does ACS when we bring up AP mode . ath10k has the below
fall back mechanism to fetch current operating channel in rx (it will
check for the next channel tracking variable if the current one is NULL)

	[scan channel] --> [rx channel] --> [peer channel] -->
	[vdev channel] -->  [any vdev channel] --> [target oper channel]

'scan channel' and 'target operating channel' are directly fetched from
firmware events. All the others should be updated by mac80211.

During ACS scan we wouldn't have a valid channel context
assigned from mac80211 ('ar->rx_channel'), and also relying on
('ar->scan_channel') is not helpful (it becomes NULL when it goes to
BSS channel and also when the scan event is completed). In short we
cannot always rely on these two channel tracking variables.

'Target Operating Channel' (ar->tgt_oper_chan) seems to keep track of
the current operating even while we are doing ACS scan and etc. Hence
remove this un-necessary warning message and continue with
target_operating channel. At the worst case scenario when the target
operating channel is invalid (NULL) we already have an ath10k warning
message to notify we really don't have a proper channel configured in
rx to update the rx status("no channel configured; ignoring frame(s)!")

Mohammed Shafi Shajakhan fb7caababc ath10k: fix crash during card removal
Usually when the firmware crashes we check for the value
'FW_IND_EVENT_PENDING' in 'FW_INDICATOR_ADDRESS' and proceed with
disabling the irq and dumping firmware 'crash dump'. Now
when the PCI card is unplugged from the device the PCI controller
seems to generate a spurious interrupt after some time which
was as treated a firmware crash and resulting in the below race
condition (and eventually crashing the system)

	ath10k_core_unregister -> ath10k_core_free_board_files

	...... device unplug spurious interrupt .........

	ath10k_pci_taklet -> ath10k_pci_fw_crashed_dump  ...etc

Clearly even after the firmware board files related data structure
is freed up we are getting a spurious interrupt from PCI with 0xfffffff
in the 'FW_INDICATOR_ADDRESS' resulting in scheduling of the pci tasklet
and doing a crash dump, printing f/w board related info resulting in the
below crash. Fix this by detecting this spurious interrupt in ath10k PCI
irq handler itself and return IRQ_NONE. Thanks to Michal Kazior for
helping us conclude the most appropriate fix.

Lior David eb57a5b387 wil6210: abort P2P search when stopping P2P device
The nl80211 layer expects P2P search operation to be aborted
if needed when stopping P2P device. If the P2P search operation
is still running after returning from stop_p2p_device
it causes a WARN_ON and possibly a kernel crash.
Fix this by aborting the P2P search in wil_cfg80211_stop_p2p_device
and preventing P2P search from being started on a stopped P2P
device.
Note, the fix does not cover the case where a regular scan
is started on the P2P device. It will be completed in the
future when support is added for aborting a scan operation.

Bob Copeland deb85bb1da ath5k: fix misplaced default label in sifs switch
In this switch statement, the default case does not always assign
sifs.  In practice, ah->ah_bwmode cannot take values besides the
other labels, so this is not an actual problem, but it looks odd
and smatch complains thus:

    ath5k_hw_get_default_sifs() warn: missing break? reassigning 'sifs'

Silence the warning by moving default label up a line.

Rajkumar Manoharan e50525bef5 ath10k: fix deadlock while processing rx_in_ord_ind
commit 5c86d97bcc ("ath10k: combine txrx and replenish task")
introduced deadlock while processing rx in order indication message
for qca6174 based devices. While merging replenish and txrx tasklets,
replenish task should be called out of htt rx ring locking since it
is also try to acquire the same lock.

Unfortunately this issue is not exposed by other solutions (qca988x,
qca99x0 & qca4019), as rx_in_ord_ind message is specific to qca6174
based devices. This patch fixes

Vasanthakumar Thiagarajan 8e100354a9 ath10k: fix cycle counter wraparound handling for QCA4019
In QCA4019, cycle counter wraparound is not tied to rx
clear counter. Each counter would wraparound individually
and after wraparound the respective counter will be reset
to 0x7fffffff while other counter still running unaffected.
Define a new wraparound type for this behaviour and handle
it separately so that rx clear counter wraparound is also
handled just like cycle counter. With this type of
wraparound we can accurately compute and report channel
active/busy time when any of the counter overflows.

Vasanthakumar Thiagarajan 26c197600b ath10k: define an enum to enable cycle counter wraparound logic
QCA988X hw implements a different cycle counter wraparound
behaviour when compared to QCA4019. To properly handle different
wraparound logic for these chipsets replace already available
bool hw_params member, has_shifted_cc_wraparound, with an
enum which could be extended to handle different wraparound
behaviour. This patch keeps the existing logic functionally
same and a prepares cycle counter wraparound handling to
extend for other chips.

Mohammed Shafi Shajakhan 5269c65900 ath10k: fix CCK h/w rates for QCA99X0 and newer chipsets
CCK hardware table mapping from QCA99X0 onwards got revised.
The CCK hardware rate values are in a proper order wrt. to
rate and preamble as below

ATH10K_HW_RATE_REV2_CCK_LP_1M = 1,
ATH10K_HW_RATE_REV2_CCK_LP_2M = 2,
ATH10K_HW_RATE_REV2_CCK_LP_5_5M = 3,
ATH10K_HW_RATE_REV2_CCK_LP_11M = 4,
ATH10K_HW_RATE_REV2_CCK_SP_2M = 5,
ATH10K_HW_RATE_REV2_CCK_SP_5_5M = 6,
ATH10K_HW_RATE_REV2_CCK_SP_11M = 7,

This results in reporting of rx frames (with CCK rates)
totally wrong for QCA99X0, QCA4019. Fix this by having
separate CCK rate table for these chipsets with rev2 suffix
and registering the correct rate mapping to mac80211 based on
the new hw_param (introduced) 'cck_rate_map_rev2' which shall
be true for any newchipsets from QCA99X0 onwards

Vasanthakumar Thiagarajan dc73787b8b ath10k: fix some of the macro definitions of HTT_RX_IND message
Only five bits are defined to pass tid information in HTT_RX_IND
message, so the mask which can be used to extract tid should be 0x1f
instead of the current 0x3f. Also, macros which can be used to extract
flush_valid and release_valid bits have to be left shifted one bit less
because these information follow the tid right after. This patch does
not really fix anything functionally because these macros are not used
currently.
