34d5629d2c ath10k: limit available channels via DT ieee80211-freq-limit
Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
the RX and TX path. These filtered channel can in theory still be used by
the hardware but the signal strength is reduced so much that it makes no
sense.

There is already a DT property to limit the available channels but ath10k
has to manually call this functionality to limit the currrently set wiphy
channels further.

84f16fbb62 wil6210: fix RX buffers release and unmap
RX SKBs are released in both wil6210 rmmod and RX handle.
As there is no lock to protect the buffers DMA unmap,
the SKB pointer in buff_arr is used to check if the buffer
memory was already released.
Setting wil->rx_buff_mgmt.buff_arr[buff_id].skb to NULL before the DMA
memory unmap will prevent duplicate unmapping of the same memory.
Move the buffer ID to the free list also in case the SKB is NULL.

df2b53884a wil6210: prevent usage of tx ring 0 for eDMA
In enhanced DMA ring 0 is used for RX ring, hence TX ring 0
is an unused element in ring_tx and ring2cid_tid arrays.
Initialize ring2cid_tid CID to WIL6210_MAX_CID to prevent a false
match of CID 0.
Go over the ring_tx and ring2cid_tid from wil_get_min_tx_ring_id
and on to prevent access to index 0 in eDMA.

06ae8dc004 ath10k: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
	int stuff;
        void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This issue was detected with the help of Coccinelle.

a9911937e7 ath10k: schedule hardware restart if WMI command times out
When running in AP mode, ath10k sometimes suffers from TX credit
starvation. The issue is hard to reproduce and shows up once in a
few days, but has been repeatedly seen with QCA9882 and a large
range of firmwares, including 10.2.4.70.67.

Once the module is in this state, TX credits are never replenished,
which results in "SWBA overrun" errors, as no beacons can be sent.
Even worse, WMI commands run in a timeout while holding the conf
mutex for three seconds each, making any further operations slow
and the whole system unresponsive.

The firmware/driver never recovers from that state automatically,
and triggering TX flush or warm restarts won't work over WMI. So
issue a hardware restart if a WMI command times out due to missing
TX credits. This implies a connectivity outage of about 1.4s in AP
mode, but brings back the interface and the whole system to a usable
state. WMI command timeouts have not been seen in absent of this
specific issue, so taking such drastic actions seems legitimate.

filter reset is needed and skip the reset_rx_filter for
WCN3990.

User controls @idx which to be used as index of hwsim_world_regdom_custom.
So, It can be exploited via Spectre-like attack. (speculative execution)

This kind of attack leaks address of hwsim_world_regdom_custom,
It leads an attacker to bypass security mechanism such as KASLR.

So sanitize @idx before using it to prevent attack.

I leveraged strategy [1] to find and exploit this gadget.

38cb87ee47 cfg80211: make wmm_rule part of the reg_rule structure
Make wmm_rule be part of the reg_rule structure. This simplifies the
code a lot at the cost of having bigger memory usage. However in most
cases we have only few reg_rule's and when we do have many like in
iwlwifi we do not save memory as it allocates a separate wmm_rule for
each channel anyway.

This also fixes a bug reported in various places where somewhere the
pointers were corrupted and we ended up doing a null-dereference.

bd1d395070 ath10k: fix kernel panic by moving pci flush after napi_disable
When continuously running wifi up/down sequence, the napi poll
can be scheduled after the CE buffers being freed by ath10k_pci_flush

Steps:
  In a certain condition, during wifi down below scenario might occur.

ath10k_stop->ath10k_hif_stop->napi_schedule->ath10k_pci_flush->napi_poll(napi_synchronize).

In the above scenario, CE buffer entries will be freed up and become NULL in
ath10k_pci_flush. And the napi_poll has been invoked after the flush process
and it will try to get the skb from the CE buffer entry and perform some action on that.
Since the CE buffer already cleaned by pci flush this action will create NULL
pointer dereference and trigger below kernel panic.

     combined with some really hacky userspace implementations. This is
     only for GNSS receivers, but you have to start somewhere, and this

b72ae8cac0 PCI: Add PCI_DEVICE_DATA() macro to fully describe device ID entry
There are a lot of examples in the kernel where PCI_VDEVICE() is used and
still looks not so convenient due to additional driver_data field attached.

Introduce PCI_DEVICE_DATA() macro to fully describe device ID entry in
shortest possible form. For example,

  before:

    { PCI_VDEVICE(INTEL, PCI_DEVICE_ID_INTEL_MRFLD),
      (kernel_ulong_t) &dwc3_pci_mrfld_properties, },

  after:

    { PCI_DEVICE_DATA(INTEL, MRFLD, &dwc3_pci_mrfld_properties) },

Drivers can be converted later on in independent way.

While here, remove the unused macro with the same name from Ralink wireless
driver.

The kernel BUG happens when wowl is enabled from firmware. In
brcmf_wiphy_wowl_params(), cfg is a NULL pointer because it is
drvr->config returned from wiphy_to_cfg(), and drvr->config is not set
yet. To fix it, set drvr->config before brcmf_setup_wiphy() which
calls brcmf_wiphy_wowl_params().

Kalle Valo says:

====================
wireless-drivers-next patches for 4.19

This time a bigger pull request as we have two new Mediatek drivers
MT76x2u (CONFIG_MT76x2U) and MT76x0U (CONFIG_MT76x0U). Also iwlwifi got
support for the new IEEE 802.11ax standard, the successor for
802.11ac. And naturally smaller new features and bugfixes all over.

Major changes:

wcn36xx

* fix WEP in client mode

wil6210

* add support for Talyn-MB (Talyn ver 2.0) device

* add support for enhanced DMA firmware feature

iwlwifi

* implement 802.11ax D2.0

* support for the new 22560 device family

* new PCI IDs for 22000 and 22560

qtnfmac

* implement cfg80211 power management callback

* enable multiple SSIDs scan support

* qtnfmac: implement basic WoWLAN support

mt7601u

* fall back to software encryption for hw unsupported ciphers

* enable 802.11 Management Frame Protection (MFP)

mt76

* support setting RTS threshold

* add USB support

* add support for MT76x2u devices

* add support for MT76x0U devices

mwifiex

* allow user space to set all other IEs except WMM IE

rsi

* add firmware support for AP+BT dual mode
