Aniket Nagarnaik 17e524b1b6 mwifiex: fix NULL pointer dereference during hidden SSID scan
This NULL pointer dereference is observed during suspend resume
stress test. All pending commands are cancelled when system goes
into suspend state. There a corner case in which host may receive
response for last scan command after this and try to trigger extra
active scan for hidden SSIDs.

The issue is fixed by adding a NULL check to skip that extra scan.

Fixes: 2375fa2b36 (mwifiex: fix unable to connect hidden SSID..)

Aniket Nagarnaik 2c3da96126 mwifiex: don't always include ht/vht info in tdls confirm frame
Current TDLS implementation always includes ht/vht information
in tdls setup confirm frame which causes teardown by legacy
peer station after TDLS handshake. We will inclue ht/vht
capabilities in tdls setup confirm frame only if peer station
supports it to fix this problem.

Xinming Hu 02421dd3f6 mwifiex: NULL check for cfg80211_inform_bss()
cfg80211_inform_bss would return null in some cases, such as
memory allocation failure.

This patch adds sanity check for this case, to avoid possible

Xinming Hu 9a9053c342 mwifiex: fix driver init failure under memory pressure
64k Tx and Rx buffers are allocated during driver initialization
for SDIO level data aggregations. When host is under memory
pressure situation, kzalloc() request for 64k may fail.

We will try allocating 32k buffers and disable our rx single port
aggreagation feature in this situation.

If the allocation still fails, we will disable our sdio multport
aggregation feature as well. In this way, we will transmit and
receive packets one by one, thus reduce the demand for big
memory.

Arend van Spriel 95ef12394a brcmfmac: introduce brcmf_net_detach() function
In case of error during brcmf_bus_start() the network interfaces were
freed using free_netdev(). However, the interfaces may have additional
memory allocated which is not freed. The netdev has destructor set to
brcmf_cfg80211_free_netdev() which frees the additional memory if
allocated and call free_netdev(). The brcmf_net_detach() either calls
brcmf_cfg80211_free_netdev() directly or uses unregister_netdev() when
struct net_device::reg_state indicates the netdev was registered.

bit more consistent. The firmware console output is only logged when
FWCON debug level is enabled.

index as the primary interface we use the bsscfg index as index in the

index and not the bsscfg index. So we need a mapping of interface index
to bsscfg index, which can be determined upon handle adding the interface.

Peter Oh 44acedb00b ath: use PRI value given by spec for fixed PRI
PRI value is used as divider when DFS detector analyzes candidate
radar pulses.
If PRI deviation is big from its origin PRI, DFS detector could miss
valid radar reports since HW often misses detecting radar pulses and
causes long interval value of pulses.

For instance from practical results, if runtime PRI is calculated as
1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
the modular remainder will be 1409 and the delta between the remainder
and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
As a result this radar report will be ignored even though it's valid.

By using spec defined PRI for fixed PRI, we can correct this error.

The number of pulses per burst on Japan chirp radar is

pulse detection other than bursts, use the pulse number

Also using the highest number helps to avoid false detection.

Oleksij Rempel e904cf6fe2 ath9k_htc: introduce support for different fw versions
Current kernel support only one fw name with theoretically only one
fw version located in “firmware/htc_[9271|7010].fw”. Which is ok so far we
have only one fw version (1.3). After we realised new fw 1.4, we faced
compatibility problem which was decided to solve by firmware name and
location:
- new firmware is located now in
	firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
- old version 1.3 should be on old place, so old kernel have no issues
	with it.
- new kernels including this patch should be able to try different
	supported (min..max) fw version.
- new kernel should be able to support old fw location too. At least for
	now.

At same time this patch will add new module option which should allow user
to play with development  fw version without replacing stable one. If user
will set “ath9k_htc use_dev_fw=1” module will try to find
firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use
stable version: for example...1.4.0.fw.

Bob Copeland b6c7bafa7d ath10k: implement mesh support
Add support for mesh to ath10k.  We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.

Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode.  As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true.  The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.

When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:

    ip link set wlan0 down
    iw dev wlan0 set type mp
    ip link set wlan0 up
    iw dev wlan0 set freq 5745 80 5775

Vivek Natarajan 7b7da0a021 ath10k: drop probe responses when too many are queued
In a noisy environment, when multiple interfaces are created,
the management tx descriptors are fully occupied by the probe
responses from all the interfaces. This prevents a new station
from a successful association.

Fix this by limiting the probe responses when the specified
threshold limit is reached.

Vasanthakumar Thiagarajan a925a37639 ath10k: fix DMA alloc failure for target requested memory chunks
During long hours of stress testing like AP interface up/down along
with continuous ping flood from a station doing connect/disconnect,
it is observed that the system is not able to allocate DMA consistent
memory of size > 512KB chunks as requested by firmware in WMI_SERVICE_EVENTID.
With the system memory getting fragmented during the run based on the
size of the memory requested, the failure to return physically continguous
memory of high order can happen. Once the system gets to this situation,
bringing up the wifi interface will fail and a system reboot may be needed
to make it work again. This problem is obseved with QCA99X0.

To fix this issue, allocate the DMA memory requested by firmware during
device probe time and keep it during the life time of the device. WMI service
ready event handler is changed to allocate the memory chunks if it is
not already allocated or if the memory allocated for the previous ready
event is not same as the current requested ones. After this patch the
memory usage when wifi is inactive will be inceased by few 100KB to
3MB based on the target type.

Failure happens with the following stack trace

MU-MIMO Rx involves different interpretation of

The incorrect interpretation led ath10k to report

Luciano Coelho cf8c3cff3f iwlwifi: mvm: make sure d0i3 exit work runs before suspending
If we are in d0i3 when entering suspend, we leave d0i3 so that
mac80211 can call us to remove connections or whatever before going to
suspend.  We do this by calling pm_runtime_resume() early in the slave
transport flow and reactivating it later, when the wiphy suspend flow
runs.

The problem is that we queue a work in order to leave d0i3.  If this
work hasn't run yet when the wiphy suspend flow is called, we have a
race and entering d0i3 fails (because we're still holding the
IWL_MVM_REF_EXIT_WORK reference).

To solve this, simply flush the d0i3_exit_work at the beginning of the
iwl_mvm_suspend() function.

When in AP mode, we need beacons from other APs for HT protection.
However, when there's no any associated station we will not do
any Tx and thus don't really need beacons. On the other hand, these
beacons will cause a lot of unnecessary wakeups which increase our
power consumption. Handle this by asking FW to pass beacons only when
there's at least one associated station.

definition to ath10k for QCA6164 which is a 1

The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump
will look like this:

Raja Mani 4535edbd42 ath10k: add spectral scan support for 10.4 fw
To enable/configure spectral scan parameters in 10.4 firmware, existing
wmi spectral related functions can be reused. Link those functions in
10.4 wmi ops table.

In addition, adjust bin size (only when size is 68 bytes) before reporting
bin samples to user space. The background for this adjustment is that
qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
carries band edge detection data (+32) mainly used in radar detection
purpose. Additional last 4 bytes are stripped to make bin size valid one.

This bin size adjustment will happen only for qca99x0, all other chipsets
will report proper bin sizes (64/128) without extra 4 bytes being added
at the end. The changes are validated in qca99x0 using 10.4 firmware.

Emmanuel Grumbach ecc7c518b3 iwlwifi: mvm: fix a race in D0i3 vs. Tx path
When we enter D0i3, we must stop TXing otherwise the
sequence number we use might conflict with the firmware's
internal TX. In order to do so, we have
IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
enter D0i3. There is a bug in this code since we may Tx even
if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
mvm->d0i3_ap_sta_id is not set.

To make sure that we don't have any packet in the Tx path
while we set mvm->d0i3_ap_sta_id, call synchronize_net only
after we already set mvm->d0i3_ap_sta_id.

Taehee Yoo 9ff4b6de26 rtlwifi: rtl8192cu: Remove and replace routine in hw.c and mac.c
I remove duplicated routines which related rtl92cu_set_hw_reg().

1. rtl92c_set_qos() and HW_VAR_AC_PARAM routine are similar code.
so i replace code with rtlpriv->cfg->ops->set_hw_reg().

2. rtl92c_set_mac_addr() and 'HW_VAR_ETHER_ADDR' case at
rtl92cu_set_hw_reg() routine are similar code.
so i removed rtl92c_set_mac_addr() function.
also it was not used anywhere.

3. remove HW_VAR_ACM_CTRL routine in rtl92cu_set_hw_reg().
if rtl_usb->acm_method is not EACMWAY2_SW, HW_VAR_ACM_CTRL is called
from HW_VAR_AC_PARAM. but it never called. because acm_method is always
EACMWAY2_SW. so i remove acm_method check routine
and HW_VAR_ACM_CTRL routine.

Taehee Yoo bf27cea495 rtlwifi: rtl8192cu: remove duplicated routine in hw.c and mac.c
rtl92c_set_xxx_filter is same routine with rtl92cu_set_hw_reg.
so i remove those functions that are rtl92c_set_xxx_filter.
(rtl92c_get_xxx_filter is also same reason.)
also i add code updating struct rtl_mac member variable in the
rtl92cu_set_hw_reg.
after that, no more _update_mac_setting is not useful. thus i remove that.

Raja Mani 991adf71a6 ath10k: refactor phyerr event handlers
Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.

Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.

.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.

Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with
CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.
Without this fix there will be lots of 0 msecs reported as active

Michal Kazior 6d2d51ecff ath10k: wake up queue upon vif creation
Vif's vdev_id is used as queue number. However due
to the tx pausing design in ath10k it was possible
for a new interface to be created with its tx
queue stopped (via ieee80211_stop_queues). This
could in turn leave the interface inoperable until
ath10k_mac_tx_unlock() was called.

This problem only affected multi-vif scenarios when
new interfaces were created some time later after
other interfaces have been running for some time
and had Tx queue full at some point prior.

Possible manifestation of the bug was
authentication timeout for a client vif.

Larry Finger 3544f9f150 rtlwifi: rtl8192c-common: Fix two typos
In this driver, two variables are masked by one quantity, and then tested
against a second number with more bits that the mask. Accordingly, the
test always fails. To minimize the possibility of such typos, a symbolic
definition of the mask is created and used.

The separate load and mask operations are also combined into a single
statement.

Larry Finger e41c513599 rtlwifi: rtl8192ce: rtl8192cu: Fix endian issue
Commit e996db6983 (rtlwifi: rtl8192c: Add init codes for "fw_version"
and "fw_subversion") added initialization for fw_version, but failed to
note that the variable in the firmware header is little-endian. The
following Sparse warning results:

  CHECK   drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types)
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    expected unsigned short [unsigned] [usertype] fw_version
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    got restricted __le16 [usertype] version

When fixing this problem, I noticed that several of the drivers contain
nearly identical copies of the firmware header struct, and that only the one
used in rtl8192c{e,u} had correct endian notation. The struct has been
moved into a common header, and the other drivers will be fixed in
subsequant patches.

Michal Kazior 92092fe528 ath10k: reject 11b tx fragmentation configuration
Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble
frames.

Hence implement a dummy callback just to say
fragmentation isn't supported. This effectively
prevents mac80211 from doing frame fragmentation
in software.

This fixes Tx becoming broken after setting
fragmentation threshold.

Eliad Peller 7845af35e0 wlcore: add p2p device support
When starting a p2p mgmt interface, enable its device role. This
allows us to keep the sta role disabled and scan on the dev role.

In general, p2p management interfaces cannot send vif-specific commands
to FW, as the vif role id is invalid. Only off-channel data and scans
happen on this vif, so most ops are not relevant.

If the vif is a p2p mgmt vif, block some mac80211 ops.

Configure rate policies for p2p mgmt interface, as
otherwise p2p packets come out with arbitrary rates.

Since wpa_supplicant currently doesn't support standalone
p2p device mode (without another attached managed interface),
add p2p device to the allowed interface combinations without
decreasing the allowed station count.

Moreover, increase the station count in some cases, as AP
mode usually starts as station interface, and the AP interface
is now different from the p2p management one).

Zhaoyang Liu d788ac2979 mwifiex: fix system crash observed during initialisation
System crash was observed if one of the driver initialisation
commands is timed out. The reason is our timeout handler triggers
firmware dump, meanwhile driver initialisation error paths have
already freed the adapter structure.

Firmware hasn't yet completely initialized. So collecting firmware
dump is not needed in this case. Command timeout handler is
modified in this patch to fix the crash issue.

Zhaoyang Liu 398750992e mwifiex: fix command timeout for PCIe chipsets
When WLAN interface is up and running, driver unload and
load was causing command timeout error.

We enable Rx data by updating RX ring read pointer in
init_fw_port(). It should be done when FW is completely

moving init_fw_port() call to mwifiex_init_fw_complete().

introduced the wakeup_interruptible suppression in mwifiex_complete_cmd

then added wakup_interruptible to mwifiex_cmd_timeout_func the single

Instead of doing extra work, using the standard call-chain will have the
same effect:
mwifiex_cancel_pending_ioctl

-> mwifiex_insert_cmd_to_free_q
-> mwifiex_complete_cmd
-> wake_up_interruptible

The difference is that previously the condition was not set to true,

have any consequence

CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
case it already started or starts processing the cmd.
But this was probably not working the way intended:
- it is racy: mwifiex_process_cmdresp might already have passed that
  test and is continuing to use the cmd node being recycled
- mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
  we just set to NULL
- mwifiex_recycle_cmd_node will clear the flag

The reason why it probably works is that mwifiex_cancel_pending_ioctl
is only called from mwifiex_cmd_timeout_func, where the there is little
chance of a command response still arriving

Matti Gottlieb e112018776 iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO
Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is slave on the bus(SDIO) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. When the FW wants load / unload pages, it creates an
interrupt,	and the driver uploads / downloads the page to an address in
the a specific address on the device's memory.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on SDIO in order to allow the program to
use a larger virtual space while using less physical memory on the device
itself.

Sara Sharon 26d535aedc iwlwifi: pcie: New RBD allocation model
As a preperation for multiple RX queues change the RBD
allocation model.

The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.

The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.

Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.

New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.

Oren Givon 36fb901726 iwlwifi: mvm: add the ability to trigger only monitor dumps
Change the FW debug trigger tlv to include a monitor only
option. Setting this option to true will cause fw dump triggers
to only collect monitor data and skip other dumps such as
SMEM, SRAM, CSR, PRPH, etc.
This option is used when accessing the different parts of the
firmware memory is not wanted and can cause unwanted behavior
like when debugging TX latency.

Johannes Berg 206eea7833 iwlwifi: pcie: support frag SKBs
Allow frag SKBs in PCIe and advertise the maximum number of frags
to the opmode. As a fallback. linearize the SKB if it exceeds the
maximum number of fragments. This allows using the hardware better
(filling more TBs) and should improve performance when used by the
opmode.

Also adjust tracing to be able to deal with this.

Avraham Stern 17564dde60 iwlwifi: add new TLV capability flag for gscan support
Gscan is a scan feature which is supported on certain devices only,
hence the need for a TLV flag for it. For devices that support gscan
store the gscan capabilities advertised by the FW so the driver can
report it to upper layers.

Matti Gottlieb a6c4fb4441 iwlwifi: mvm: Add FW paging mechanism for the UMAC on PCI
Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is master on the bus(PCI) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. The FW can load / unload the pages on its own.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on PCI in order to allow the program
to use a larger virtual space while using less physical memory on the
device.

Johannes Berg ca8c0f4bed iwlwifi: mvm: move TX PN assignment for CCMP to the driver
Move the TX PN assignment (for CCMP only) to the driver. This prepares
the driver for future DSO (driver segmentation offload) where it will
split an SKB into multiple MPDUs by itself.

For TDLS, split out the CCMP TX command handling so that it won't get
a PN assigned, the firmware assigns the PN in that case.

Since the CSR_DRAM_INIT_TBL_WRITE_POINTER bit wasn't set
on ict reset, in some flows (like disable ict followed by
immediate reset ict) the driver and hardware went out
of sync (the driver cleared the ict_index, while the hw
kept it intact).

Fix it by setting the flag when resetting ict.

in case of suspend/resume with unified image
(which doesn't includes reconfiguration flow).

while making sure some configurations are a bit

After this change, we no longer need the special
wowlan_d0i3 configurations done in iwl_pci_resume,
as they are already being done in the d3_resume op.
