[   88.753477] Kernel panic - not syncing: Fatal exception
[   88.759981] Rebooting in 3 seconds..

The "REG_READ(ah, AR_PHY_AGC_CONTROL)" in ath9k_hw_loadnf() does not
like being called when the hardware is asleep, leading to this crash.

The easiest way to reproduce this is trying to set nf_override while
the hardware is down:

  $ ip link set down dev wlan0
  $ echo "-85" > /sys/kernel/debug/ieee80211/phy0/ath9k/nf_override

Fixing this crash by waking the hardware up before trying to set the
noise floor. Similar to what other ath9k debugfs files do.

Tested on a Lima board from 8devices, which has a QCA 4531 chipset.

Wen Gong e6f1c0d26a ath10k: restore tx sk_buff of htt header for SDIO
ieee80211_report_used_skb of mac80211 use the frame_control of
ieee80211_hdr in sk_buff and indicate it to another function
ieee80211_mgd_conn_tx_status, then it queue work ieee80211_sta_work,
but ieee80211_is_auth(fc) in ieee80211_sta_work check fail when the
authentication has transmitted by ath10k.

When the ath10k report it with HTT_TX_COMPL_STATE_DISCARD, it will be
set without flag IEEE80211_TX_STAT_ACK, then mac80211 should try the
next authentication immeditely, but in fact mac80211 wait 1 second for
it, the reason is ieee80211_is_auth(fc) in ieee80211_sta_work check
fail for the sk_buff which is not restored, the data of sk_buff is not
the begin of ieee80211_hdr, in fact it is the begin of htt_cmd_hdr.

dmesg without this patch, it wait 1 second for the next retry when
ath10k report without IEEE80211_TX_STAT_ACK for authentication:
[ 6973.883116] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 1/3)

[ 6975.712962] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 3/3)

Restore the sk_buff make mac8011 retry the next authentication
immeditely which meet logic of mac80211.

dmesg with this patch, it retry the next immeditely when ath10k
report without IEEE80211_TX_STAT_ACK for authentication:

Vsevolod Kozlov 6fe91b69ce wilc1000: Fix use of void pointer as a wrong struct type
ac_classify() expects a struct sk_buff* as its second argument, which is
a member of struct tx_complete_data. priv happens to be a pointer to
struct tx_complete_data, so passing it directly to ac_classify() leads
to wrong behaviour and occasional panics.

Since there is only one caller of wilc_wlan_txq_add_net_pkt and it
already knows the type behind this pointer, and the structure is already
in the header file, change the function signature to use the real type
instead of void* in order to prevent confusion.

If the SKU_ID doesn't match, we don't increment the pointer and keep

We need to increment the pointer in all situtations, namely if the TLV
is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match.
So we can increment the pointer already before checking for these
conditions to solve the problem.

When the interface goes up, we have already loaded the PNVM during

values in the context so that the FW can load it again.

Call set_pnvm when the PNVM is already loaded and change the
trans_pcie implementation to accept a second call to set_pnvm when we
have already allocated and, in this case, only set the values without
allocating again.

Golan Ben Ami c61734a69c iwlwifi: mvm: reduce the print severity of failing getting NIC temp
Currently, for all devices and families, failing getting the temp
from the fw is indicated in the log as ERR.
This is too severe for two reasons:
1. The driver has a fall back - and schedules the next temp
read immediately after failing to read temp from the fw.
2. The temp read implementation in the fw is different between
HWs, and on older devices the flow is a-sync and may timeout.

Reducing the print severity from ERR to WARN will allow to
track the issue if it will appear many times, but not frighten users
if it appears once.

Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load
NVM to nic func fails and NVM is not loaded to fw properly, then fw may
behave badly and lead to some strange issue. This commit will analyze
return value and if load NVM to nic has failed, then the error code is
sent to the previous func, which will trigger WRT log collection.
iwl_fw_dbg_error_collect() func collects dump only if tri type is
FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails
trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to
collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

Emmanuel Grumbach 8c082a99ed iwlwifi: mvm: simplify iwl_mvm_dbgfs_register
No need to pass the dbgfs_dir just to assign it to mvm.
Assign to mvm and then call iwl_mvm_dbgfs_register.

This is a preparation towards the addition of a delayed
op_mode_start flow.
This will allow to split the op_mode_start flow.
Registration to debugfs must happen after we register to
mac80211 and the registration to mac80211 will soon be
delayed in certain cases. In order not to have to remember
the debugfs_dir in a separate variable, just set it into
the mvm structure so that it can be usable later.

Declare mvm->debugfs_dir in the iwl_mvm structure even when
IWLWIFI_DEBUGFS isn't enabled to simplify the source code.

RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.

This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
  will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
  that driver sent).

Dan Carpenter c202e2ebe1 ath11k: fix a locking bug in ath11k_mac_op_start()
This error path leads to a Smatch warning:

	drivers/net/wireless/ath/ath11k/mac.c:4269 ath11k_mac_op_start()
	error: double unlocked '&ar->conf_mutex' (orig line 4251)

We're not holding the lock when we do the "goto err;" so it leads to a
double unlock.  The fix is to hold the lock for a little longer.

Arnd Bergmann ca9ad549e4 carl9170: fix struct alignment conflict
Multiple structures in the carl9170 driver have alignment
impossible alignment constraints that gcc warns about when
building with 'make W=1':

drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned]
drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned]

In the carl9170_cmd structure, multiple members that have an explicit
alignment requirement of four bytes are added into a union with explicit
byte alignment, but this in turn is part of a structure that also has
four-byte alignment.

In the wlan.h header, multiple structures contain a ieee80211_hdr member
that is required to be two-byte aligned to avoid alignmnet faults when
processing network headers, but all members are forced to be byte-aligned
using the __packed tag at the end of the struct definition.

In both cases, leaving out the packing does not change the internal
layout of the structure but changes the alignment constraint of the
structure itself.

Change all affected structures to only apply packing where it does
not violate the alignment requirement of the contained structure.

Yen-lin Lai b7fd26c913 mwifiex: Report connected BSS with cfg80211_connect_bss()
When a network is moved or reconfigured on the different channel, there
can be multiple BSSes with the same BSSID and SSID in scan result
before the old one expires. Then, it can cause cfg80211_connect_result
to map current_bss to a bss with the wrong channel.

Let mwifiex_cfg80211_assoc return the selected BSS and then the caller
can report it cfg80211_connect_bss.

Hans de Goede a338c874d3 brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tablet
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.

Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.

While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.

Emil Renner Berthing ca04217add rtlwifi: use tasklet_setup to initialize rx_work_tasklet
In commit d3ccc14dfe most of the tasklets in this driver was
updated to the new API. However for the rx_work_tasklet only the
type of the callback was changed from
  void _rtl_rx_work(unsigned long data)
to
  void _rtl_rx_work(struct tasklet_struct *t).

The initialization of rx_work_tasklet was still open-coded and the
function pointer just cast into the old type, and hence nothing sets
rx_work_tasklet.use_callback = true and the callback was still called as

  t->func(t->data);

with uninitialized/zero t->data.

Commit 6b8c7574a5 changed the casting of _rtl_rx_work a bit and
initialized t->data to a pointer to the tasklet cast to an unsigned
long.

This way calling t->func(t->data) might actually work through all the
casting, but it still doesn't update the code to use the new tasklet
API.

Let's use the new tasklet_setup to initialize rx_work_tasklet properly
and set rx_work_tasklet.use_callback = true so that the callback is
called as

  t->callback(t);

without all the casting.

Ilan Peer 47ef328c20 iwlwifi: pcie: Disable softirqs during Rx queue init
When Rx queues are configured during module init, NAPI is enabled
while the Rx queue lock is held. However, since softirqs are not
disabled, it is possible that and IRQ would fire and call
iwl_pcie_rx_handle() which would also try to acquire the Rx lock.

Prevent this by disabling softirqs during Rx queue configuration,
as part of module init flow.

In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we
might access this as an array, as it's really not an array and
cannot be - there's only a single 802.11 header per frame. The
only reason for this member is for being able to access it a
bit more nicely.

On the other hand, this structure is used as a sub-struct in a
few places, and then some compilers (e.g. clang with certain

This should be harmless, but if the first two bytes are zero,

that might later cause issues if unsigned variables are used,

Haim Dreyfuss 708a39aaca iwlwifi: mvm: don't send commands during suspend\resume transition
D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).

There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.

To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

However, we _do_ need to clean up our internal state, since
mac80211 will restart the scan, and we'll otherwise get to
the WARN_ON() a few lines below for no reason whatsoever.

Johannes Berg 88181e6e21 iwlwifi: mvm: remove debugfs injection limitations
For testing features where the firmware may send some
notifications it can often be a lot easier to do that
from a test script. Remove most injection limitations
from debugfs to be able to do this.

Johannes Berg afc857bc2a iwlwifi: mvm: add notification size checks
We shouldn't trust the firmware with the sizes (or contents)
of notifications, accessing too much data could cause page
faults if the data doesn't fit into the allocated space. This
applies more on older NICs where multiple notifications can
be in a single RX buffer.

Add a general framework for checking a minimum size of any
notification in the RX handlers and use it for most. Some RX
handlers were already checking and I've moved the checks,
some more complex checks I left and made them _NO_SIZE for
the RX handlers.

Arnd Bergmann b64acb28da ath9k: fix build error with LEDS_CLASS=m
When CONFIG_ATH9K is built-in but LED support is in a loadable
module, both ath9k drivers fails to link:

x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_deinit_leds':
gpio.c:(.text+0x36): undefined reference to `led_classdev_unregister'
x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_init_leds':
gpio.c:(.text+0x179): undefined reference to `led_classdev_register_ext'

The problem is that the 'imply' keyword does not enforce any dependency
but is only a weak hint to Kconfig to enable another symbol from a
defconfig file.

Change imply to a 'depends on LEDS_CLASS' that prevents the incorrect
configuration but still allows building the driver without LED support.

The 'select MAC80211_LEDS' is now ensures that the LED support is
actually used if it is present, and the added Kconfig dependency
on MAC80211_LEDS ensures that it cannot be enabled manually when it
has no effect.

Miaoqing Pan b55379e343 ath10k: fix wmi mgmt tx queue full due to race condition
Failed to transmit wmi management frames:

[84977.840894] ath10k_snoc a000000.wifi: wmi mgmt tx queue is full
[84977.840913] ath10k_snoc a000000.wifi: failed to transmit packet, dropping: -28
[84977.840924] ath10k_snoc a000000.wifi: failed to submit frame: -28
[84977.840932] ath10k_snoc a000000.wifi: failed to transmit frame: -28

This issue is caused by race condition between skb_dequeue and
__skb_queue_tail. The queue of ‘wmi_mgmt_tx_queue’ is protected by a
different lock: ar->data_lock vs list->lock, the result is no protection.
So when ath10k_mgmt_over_wmi_tx_work() and ath10k_mac_tx_wmi_mgmt()
running concurrently on different CPUs, there appear to be a rare corner
cases when the queue length is 1,

  CPUx (skb_deuque)			CPUy (__skb_queue_tail)
					next=list
					prev=list
  struct sk_buff *skb = skb_peek(list);	WRITE_ONCE(newsk->next, next);
  WRITE_ONCE(list->qlen, list->qlen - 1);WRITE_ONCE(newsk->prev, prev);
  next       = skb->next;		WRITE_ONCE(next->prev, newsk);
  prev       = skb->prev;		WRITE_ONCE(prev->next, newsk);
  skb->next  = skb->prev = NULL;	list->qlen++;
  WRITE_ONCE(next->prev, prev);
  WRITE_ONCE(prev->next, next);

If the instruction ‘next = skb->next’ is executed before
‘WRITE_ONCE(prev->next, newsk)’, newsk will be lost, as CPUx get the
old ‘next’ pointer, but the length is still added by one. The final
result is the length of the queue will reach the maximum value but
the queue is empty.

So remove ar->data_lock, and use 'skb_queue_tail' instead of
'__skb_queue_tail' to prevent the potential race condition. Also switch
to use skb_queue_len_lockless, in case we queue a few SKBs simultaneously.

Wen Gong 22df5e1bec ath10k: pass the ssid info to get the correct bss entity
When connect to an AP with WPA mode, ath10k need to set need_ptk_4_way to
firmware in WMI_PEER_ASSOC_CMD, then the data path is disallow in
firmware, it will be allowed untill firmware finish the 4 way handshake.

It failed with a test case with below steps:
1. configure AP with WPA mode with ssid1 SimpleConnect_a_orbvt_ch1,
   bssid1 and channel 1.
2. connect to ssid1 and ping success.
3. wait 10 seconds which is less than
   IEEE80211_SCAN_RESULT_EXPIRE(30 seconds).
4. configure AP with OPEN mode with ssid2 SimpleConnect_b_z3a00_ch1,
   but use same bssid1 and channel 1 of step 1.
5. disconnect ssid1.
6. connect to ssid2 and ping fail.

Fail reason:
When run step 6, ath10k_peer_assoc_h_crypto() called cfg80211_get_bss()
with bssid and chan info, but ssid1 and ssid2 have the same bssid and
channel, then there have 2 entry for ssid1 and ssid2 in cfg80211. The
ssid1's order is before ssid2 in bss_list, and ssid1's age is less than
the expire time which is IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). Then
ssid1's entry is selected and ath10k_peer_assoc_h_crypto() parsed it and
get the rsnie and then need_ptk_4_way is set to firmware, so data path
is disallowed and it will not receive 4 way handshake for OPEN mode,
so ping fail in step 6.

This patch is to pass the ssid info to cfg80211_get_bss() as same as
cfg80211_mlme_assoc() and cfg80211_mlme_auth(), then it will find the
correct bss entry in above test case, then case success.

For AP mode, the ssid info is filled in ieee80211_start_ap(), for STATION
mode, it is filled in ieee80211_mgd_assoc(). Tested for both AP/STATION
mode with QCA6174 hw3.2 PCI, it is success start/connect/ping for
WPA/OPEN mode.

Carl Huang 442545ba54 ath10k: allow dynamic SAR power limits via common API
ath10k assigns ath10k_mac_set_sar_specs to ath10k_ops, and
this function is called when user space application calls
NL80211_CMD_SET_SAR_SPECS. ath10k also registers SAR type,
and supported frequency ranges to wiphy so user space can
query SAR capabilities.

This SAR power limitation is compared to regulatory txpower
and selects the minimal one to set when station is connected.
Otherwise, it delays until the station is connected. If the
station is disconnected, it returns to regulatory txpower.

This feature is controlled by hw parameter: dynamic_sar_support.

Johannes Berg 38ec7c6b6b virt_wifi: fix deadlock on RTNL
Fix a regression where everything in virt_wifi would just hang. This
happened due to overlapping changes between commit a05829a722
("cfg80211: avoid holding the RTNL when calling the driver") which
had originally needed to change the locking, but then I introduced
commit 2fe8ef1062 ("cfg80211: change netdev registration/unregistration
semantics") instead. virt_wifi somehow fell through the cracks when
I undid all the previous locking changes. Fix it now.

Shayne Chen ba4590942e mt76: testmode: make tx queued limit adjustable
Originally, tx queued limit is set to 1000 to prevent from running out
of tx token. If a new testmode tx is triggered while the previous one
hasn't finished yet, we'll wait a period of time until tx_done equals to
tx_queued. Normally, current queued limit can finish in 10 seconds.

However, if ipg is configured to a larger value, less than 1000 packets
can be done in the default timeout period, which may lead to a crash
when a new testmode tx triggered.

To deal with this, make tx queued limit dynamically adjusted according
to ipg value.

Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.

Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).

Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

Stanislaw Gruszka 4832bb371c iwl4965: do not process non-QOS frames on txq->sched_retry path
We have already WARN_ON(!qc) for non-QOS frame on txq->sched_retry path,
but we continue to process, what makes no sense since tid is not
initialized. Non QOS frame should never happen when aggregation
is enabled on queue, so do not process that.

Tony Lindgren cb88d01b67 wlcore: Fix command execute failure 19 for wl12xx
We can currently get a "command execute failure 19" error on beacon loss
if the signal is weak:

wlcore: Beacon loss detected. roles:0xff
wlcore: Connection loss work (role_id: 0).
...
wlcore: ERROR command execute failure 19
...
WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803
...
(wl12xx_queue_recovery_work.part.0 [wlcore])
(wl12xx_cmd_role_start_sta [wlcore])
(wl1271_op_bss_info_changed [wlcore])
(ieee80211_prep_connection [mac80211])

Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware,
and seems to mean that the firmware no longer wants to see the quirk
handling for WLCORE_QUIRK_START_STA_FAILS done.

This quirk got added with commit 18eab43070 ("wlcore: workaround
start_sta problem in wl12xx fw"), and it seems that this already got fixed
in the firmware long time ago back in 2012 as wl18xx never had this quirk
in place to start with.

As we no longer even support firmware that early, to me it seems that it's
safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks
like earlier firmware got disabled back in 2013 with commit 0e284c074e
("wl12xx: increase minimum singlerole firmware version required").

If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any
firmware that the driver works with, we can simply revert this patch and
add extra checks for firmware version used.

With this fix wlcore reconnects properly after a beacon loss.

Johannes Berg 3d372c4edf iwlwifi: pcie: reschedule in long-running memory reads
If we spin for a long time in memory reads that (for some reason in
hardware) take a long time, then we'll eventually get messages such
as

  watchdog: BUG: soft lockup - CPU#2 stuck for 24s! [kworker/2:2:272]

This is because the reading really does take a very long time, and
we don't schedule, so we're hogging the CPU with this task, at least
if CONFIG_PREEMPT is not set, e.g. with CONFIG_PREEMPT_VOLUNTARY=y.

Previously I misinterpreted the situation and thought that this was
only going to happen if we had interrupts disabled, and then fixed
this (which is good anyway, however), but that didn't always help;
looking at it again now I realized that the spin unlock will only
reschedule if CONFIG_PREEMPT is used.

In order to avoid this issue, change the code to cond_resched() if
we've been spinning for too long here.

for AX210.

This also corrects the AX210 workaround to be done only on
discrete (non-integrated) devices, otherwise the registers
have no effect.

Emmanuel Grumbach 0f8d5656b3 iwlwifi: queue: don't crash if txq->entries is NULL
The code was really awkward, we would first dereference
txq->entries when calling iwl_txq_genX_tfd_unmap and then
we would check that txq->entries is non-NULL.
Fix that by exiting if txq->entries is NULL.

Emmanuel Grumbach a800f95858 iwlwifi: fix the NMI flow for old devices
I noticed that the flow that triggers an NMI on the firmware
for old devices (tested on 7265) doesn't work.
Apparently, the firmware / device is still in low power when
we write the register that triggers the NMI. We call the
"grab_nic_access" function to make sure the device is awake
but that wasn't enough. I played with this and noticed that
if we wait 1 ms after the device reports it is awake before
we write to the NMI register, the device always sees our
write and the firmware gets properly asserted.

Triggering an NMI to the firmware can be done with the
debugfs hook:
echo 1 > /sys/kernel/debug/iwlwifi/0000\:00\:03.0/iwlmvm/fw_nmi

What happened before is that the firmware would just stall
without running its NMI routine. Because of that the driver
wouldn't get the "firmware crashed" interrupt. After a while
the driver would notice that the firmware is not responding
to some command and it would read the error data from the
firmware, but this data is populated in the NMI service
routine in the firmware which was not called. So in the logs
it looked like:

iwlwifi 0000:00:03.0: Error sending REPLY_ERROR: time out after 2000ms.
iwlwifi 0000:00:03.0: Current CMD queue read_ptr 33 write_ptr 34

Notice the first line: "Microcode SW error detected:" which
is printed in the driver's ISR, which means that the driver
actually got an interrupt from the firmware saying that it
crashed. And then we have the properly populated error data.

Johannes Berg 2fe8ef1062 cfg80211: change netdev registration/unregistration semantics
We used to not require anything in terms of registering netdevs
with cfg80211, using a netdev notifier instead. However, in the
next patch reducing RTNL locking, this causes big problems, and
the simplest way is to just require drivers to do things better.

Change the registration/unregistration semantics to require the
drivers to call cfg80211_(un)register_netdevice() when this is
happening due to a cfg80211 request, i.e. add_virtual_intf() or
del_virtual_intf() (or if it somehow has to happen in any other
cfg80211 callback).

Otherwise, in other contexts, drivers may continue to use the
normal netdev (un)registration functions as usual.

Internally, we still use the netdev notifier and track (by the
new wdev->registered bool) if the wdev had already been added
to cfg80211 or not.

Linus Lüssing 3e6b9cf534 ath10k: increase rx buffer size to 2048
Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.

For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.

This patch now increases the maxmimum frame size from 1528 to 1656
bytes.

Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.

Fix originally found and developed by Ben Greear.

Luca Pesce e862a3e408 brcmfmac: clear EAP/association status bits on linkdown events
This ensure that previous association attempts do not leave stale statuses
on subsequent attempts.

This fixes the WARN_ON(!cr->bss)) from __cfg80211_connect_result() when
connecting to an AP after a previous connection failure (e.g. where EAP fails
due to incorrect psk but association succeeded). In some scenarios, indeed,
brcmf_is_linkup() was reporting a link up event too early due to stale
BRCMF_VIF_STATUS_ASSOC_SUCCESS bit, thus reporting to cfg80211 a connection
result with a zeroed bssid (vif->profile.bssid is still empty), causing the
WARN_ON due to the call to cfg80211_get_bss() with the empty bssid.

A goto statement is also no longer needed. Thus adjust an if branch.

Zhi Han 1dac51269d mt7601u: check the status of device in calibration
When the usb device being plugged out, before ieee80211 gets to know the
hw being removed, it gets to know that the association status changed,
and thus ask for the device to do the calibration. This causes error as
the hw is absent.

This can be avoid by checking the status of the device before sending
the calibration request to the device.

The commit ba8f6f4ae2 ("iwlwifi: dbg: add dumping special device

seems causing a regression, a GPF triggered at firmware loading.
Basically we shouldn't modify the firmware data that may be provided
as read-only.

This patch drops the code that caused the regression and keep the tlv
data as is.

request_firmware_nowait() which schedules another work is used to load
firmware when USB is probing. If USB is unplugged before running the

Though we wait for completion of firmware work before freeing the hw,
firmware callback rises completion too early. So I move it to the

Wen Gong e2f8b74e58 ath10k: prevent deinitializing NAPI twice
It happened "Kernel panic - not syncing: hung_task: blocked tasks" when
test simulate crash and ifconfig down/rmmod meanwhile.

Test steps:

1.Test commands, either can reproduce the hang for PCIe, SDIO and SNOC.
echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash;sleep 0.05;ifconfig wlan0 down

Jouni Malinen ca2848022c ath9k: Postpone key cache entry deletion for TXQ frames reference it
Do not delete a key cache entry that is still being referenced by
pending frames in TXQs. This avoids reuse of the key cache entry while a
frame might still be transmitted using it.

To avoid having to do any additional operations during the main TX path
operations, track pending key cache entries in a new bitmap and check
whether any pending entries can be deleted before every new key
add/remove operation. Also clear any remaining entries when stopping the
interface.

ath_key_delete() call to be postponed to be handled after the upper

Jouni Malinen 56c5485c9e ath: Use safer key clearing with key cache entries
It is possible for there to be pending frames in TXQs with a reference
to the key cache entry that is being deleted. If such a key cache entry
is cleared, those pending frame in TXQ might get transmitted without
proper encryption. It is safer to leave the previously used key into the
key cache in such cases. Instead, only clear the MAC address to prevent
RX processing from using this key cache entry.

This is needed in particularly in AP mode where the TXQs cannot be
flushed on station disconnection. This change alone may not be able to
address all cases where the key cache entry might get reused for other
purposes immediately (the key cache entry should be released for reuse
only once the TXQs do not have any remaining references to them), but
this makes it less likely to get unprotected frames and the more
complete changes may end up being significantly more complex.

Carl Huang d1b0c33850 ath11k: implement suspend for QCA6390 PCI devices
Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.

At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.

During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state.  During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

Carl Huang 43ed15e1ee ath11k: put hw to DBS using WMI_PDEV_SET_HW_MODE_CMDID
It's recommended to use wmi command WMI_PDEV_SET_HW_MODE_CMDID to put hardware
to dbs mode instead of wmi_init command. This fixes a few strange stability
issues.

There was no way to detect if the firmware crashed so add a warning. At the
moment the firmware is not restarted or anything like that, so when this
happens ath11k modules need to be reloaded.

Wen Gong 5dadbe4e37 ath10k: add atomic protection for device recovery
When it has more than one restart_work queued meanwhile, the 2nd
restart_work is very easy to break the 1st restart work and lead
recovery fail.

Add a flag to allow only one restart work running untill
device successfully recovered.

It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this
flag again, because it is clear in ath10k_core_start. The function
ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do
many things and drv_start(call to ath10k_core_start) is 1st thing,
when drv_start complete, it does not mean restart complete. So it
add new flag and clear it in ath10k_reconfig_complete, because it
is the last thing called from drv_reconfig_complete of function
ieee80211_reconfig, after it, the restart process finished.

Johannes Berg 906d4eb844 iwlwifi: support firmware reset handshake
There are some races in the hardware that can possibly lead to
a bus lockup later during a restart when we manage to kill the
firmware at a bad time (while it's accessing the bus).

To work around this, add support for a new handshake between
firmware and driver to ensure that the firmware is in a well-
known state before we kill it.

Sara Sharon caf4637712 iwlwifi: mvm: fix a race in CSA that caused assert 0x3420
When we get a channel switch with a very long quiet period, we schedule
a work to disconnect after a while. This work runs in background. In the
meanwhile, we keep getting beacons and sending FW modify command for each.
This has a potential race, where we modify the CSA after we aborted it.

Protect the flow by setting csa_failed to true in case we abort, and check
it before sending the modify command.

This required a modification to the way we treat csa_failed in
iwl_mvm_post_channel_switch:
1. The variable isn't being reset anymore, so we can still look at it in
iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when
starting a new CSA.
2. There is no more early return in case of csa_failed. This is fine,
since before this patch csa_failed was set only for GO, and for GO the
function is only resetting the power settings, which we want to restore
even in case of failure.

We can remove this convoluted way to get the hardware version
that was needed because of a bug in the register's
configuration.

Moreover, since we no longer need to access the PRPH
registers, we no longer need to wake up the device,
request ownership, etc...
Remove all that.

This allows us to get the rid of the obsolete comment
about the AUX bus MISC address space which should have
been moved when this code was moved away from here.

ofdm_index[] is used to indicate how many power compensation is needed to
current thermal value. For internal PA module or 2.4G band, the min_index
is different from other cases.

This issue originally is reported by Dan. He found the size of ofdm_index[]
is 2, but access index 'i' may be equal to 2 if 'rf' is 2 in case of
'is2t'.

In fact, the chunk of code is added to wrong place, so move it back to
proper place, and then power compensation and buffer overflow are fixed.

Chin-Yen Lee 3324e05eca rtw88: reduce polling time of IQ calibration
When 8822CE is associating with AP, driver will poll status bit of
IQ calibration to confirm the IQ calibration is done, and then move on
the association process. Current polling time for IQ calibration is 6
seconds.

But occasionally driver fails in polling the status bit because the status
bit is not set after IQ calibration is done. When it happends, association
process will be serieously delayed up to 6 seconds. To avoid it, we reduce
polling time to 300ms, in which the IQ calibration can be done.

and there was no demand for channel 144 at that time. Although HW
actually supports channel 144, driver didn't announce channel 144.
Therefore, channel 144 (20 MHz), channel 142 (40 MHz) and channel
138 (80 MHz) couldn't be used.

Today, channel 144 has been enabled by regulations and
is gradually being supported. With test requirements,
we declare hw supports channel 144.

Colin Ian King 88c15a6fbd rtw88: coex: fix missing unitialization of variable 'interval'
Currently the variable 'interval' is not initialized and is only set
to 1 when oex_stat->bt_418_hid_existi is true.  Fix this by inintializing
variable interval to 0 (which I'm assuming is the intended default).

Christophe JAILLET 01b660b87e mwl8k: switch from 'pci_' to 'dma_' API
he wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'mwl8k_rxq_init()' and 'mwl8k_txq_init()'
GFP_KERNEL can be used because this flag is already used in a 'kcalloc()'
call, just a few line below.

When memory is allocated in 'mwl8k_firmware_load_success()' GFP_KERNEL can
be used because this flag is already used within 'ieee80211_register_hw()'
which is called just a few line below.

Ryder Lee d8d59f66d1 mt76: mt7615: support 16 interfaces
When looking for a MAC address slot, start by using main BSSID slots 1-3,
afterwards use 16 repeater mode BSSID slots, then start using the slots
usually used for AP mode.

This search order should prevent unnecessary conflicts with AP mode interfaces
on the same PHY.

Note that two PHYs share global 32 omac slots with each other.
