[ Upstream commit 2836b4f224d4fd7d1a2b23c3eecaf0f0ae199a74 ]
Since virtio does not provide it's own ndo_features_check handler,
TSO, and now checksum offload, are disabled for stacked vlans.
Re-enable the support and let the host take care of it. This
restores/improves Guest-to-Guest performance over Q-in-Q vlans.

[ Upstream commit cc6e9de62a7f84c9293a2ea41bc412b55bb46e85 ]
At least some of the be2net cards do not seem to be capabled
of performing checksum offload computions on Q-in-Q packets.
In these case, the recevied checksum on the remote is invalid
and TCP syn packets are dropped.
This patch adds a call to check disbled acceleration features
on Q-in-Q tagged traffic.

[ Upstream commit 486181bcb3248e2f1977f4e69387a898234a4e1e ]
In their infinite wisdom, and never ending quest for end user frustration,
Lenovo has decided to use a new USB device ID for the wwan modules in
their 2017 laptops. The actual hardware is still the Sierra Wireless
EM7455 or EM7430, depending on region.

Validate buffer length has the minimum needed size
when sending management frame to protect against
possible buffer overrun.

Peer creation in firmware fails if last peer deletion is still
in progress.

from host driver.

If host driver fails to send WMI_VDEV_DOWN_CMDID, firmware will drop
further packets as vdev TX PAUSE reset is done as part of VDEV_DOWN.
Send vdev down to firmware if STA fails to associate.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory beyond the endpoint array should a
malicious device lack the expected endpoints.

commit 3c8cb9ad032d737b874e402c59eb51e3c991a144 upstream.
Command buffers (skb's) are allocated by the main driver, and freed upon
the last use. That last use is often in mwifiex_free_cmd_buffer(). In
the meantime, if the command buffer gets used by the PCI driver, we map
it as DMA-able, and store the mapping information in the 'cb' memory.
However, if a command was in-flight when resetting the device (and
therefore was still mapped), we don't get a chance to unmap this memory
until after the core has cleaned up its command handling.
Let's keep a refcount within the PCI driver, so we ensure the memory
only gets freed after we've finished unmapping it.
Noticed by KASAN when forcing a reset via:
echo 1 > /sys/bus/pci/.../reset
The same code path can presumably be exercised in remove() and
shutdown().

This bug has been around in different forms for a while. It was sort of
noticed in commit 955ab095c51a ("mwifiex: Do not kfree cmd buf while
unregistering PCIe"), but it just fixed the double-free, without
acknowledging the potential for use-after-free.

commit e7ee74b56f23ba447d3124f2eccc32033cca501d upstream.
This event is used by the Firmware to limit the RX BA win size
for a specific link.
The event handler updates the new size in the mac's sta->sta struct.
BA sessions opened for that link will use the new restricted
win_size. This limitation remains until a new update is received or
until the link is closed.

commit 42c7372a111630dab200c2f959424f5ec3bf79a4 upstream.
When starting a new BA session, we must pass the win_size to the FW.
To do this we take max_rx_aggregation_subframes (BA RX win size)
which is stored in ieee80211_sta structure (e.g per link and not per HW)
We will use the value stored per link when passing the win_size to
firmware through the ACX_BA_SESSION_RX_SETUP command.

commit 50ea05efaf3bed7dd34bcc2635a8b3f53bd0ccc1 upstream.
Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.

Added vendor commands for low level control over
RF sectors. It allows user space a fine-grained control
over RF characteristics for TX and RX, such as direction
and gain of TX/RX. Main usages are debugging and diagnostics,
but also operational use cases.
API includes getting/setting a specific RF sector
configuration, as well as getting/setting the selected
sector which is used to communicate with a station.

Current handling of wil->platform_ops.suspend can lead to
bad cases, as wil_status_suspending was cleared before
wil_status_resuming was set and bus request voting was restored
too late.
In addition, bus voting in suspend should be done only at the end
of he suspend flow.

Move the bus request restore to be done prior to
sending wmi_resume to the device, as the device can restore
the data path upon receiving this command.

There is a design limitation in host driver. Driver
sends regulatory_hint_user for both user-space and
11d country to kernel. So when wiphy re-registration
happens, kernel tells the source as USER even for 11d.
And per driver logic the 11d needs to be disabled
if INI gCountryCodePriority is set.
To mitigate this issue, storing the country source
in the platform driver.

commit 9cc4b7cb86cbcc6330a3faa8cd65268cd2d3c227 upstream.
The driver was making changes to the skb_header without
ensuring it was writable (i.e. uncloned).
This patch also removes some boiler plate header size
checking/adjustment code as that is also handled by the
skb_cow_header function used to make header writable.

The incoming skb header may be resized if header space is
insufficient, which might change the data adddress in the skb.
Ensure that a cached pointer to that data is correctly set by
moving assignment to after any possible changes.

commit a5b60de6972decc6b50a39abb376077c3c3621c8 upstream.
This patch fixes the issue specific to AP. AP is started with WEP
security and external station is connected to it. Data path works
in this case. Now if AP is restarted with WPA/WPA2 security,
station is able to connect but ping fails.
Driver skips the deletion of WEP keys if interface type is AP.
Removing that redundant check resolves the issue.

commit 5f0a221f59ad6b72202ef9c6e232086de8c336f2 upstream.
We already ensure 64 bytes alignment and add padding if required
during skb_aggr allocation.
Alignment and padding in mwifiex_11n_form_amsdu_txpd() is redundant.
We may end up accessing more data than allocated size with this.
This patch fixes following issue by removing redundant padding.

commit 6183468a23fc6b6903f8597982017ad2c7fdefcf upstream.
Similar to commit fcd2042e8d36 ("mwifiex: printk() overflow with 32-byte
SSIDs"), we failed to account for the existence of 32-char SSIDs in our
debugfs code. Unlike in that case though, we zeroed out the containing
struct first, and I'm pretty sure we're guaranteed to have some padding
after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes
long).
So, this is the difference between:
# cat /sys/kernel/debug/mwifiex/mlan0/info
...
essid="0123456789abcdef0123456789abcdef "
...
and the correct output:
# cat /sys/kernel/debug/mwifiex/mlan0/info
...
essid="0123456789abcdef0123456789abcdef"
...

In order to preserve the connection in suspend/resume flow,
wil6210 host allows going to PCIe D3hot state in suspend,
instead of performing a full wil6210 device reset. This
requires the platform ability to initiate wakeup in case of
RX data. To check that, a new platform API is added.
In addition, add cfg80211 suspend/resume callbacks
implementation.

The WLAN driver request and free the copy engine interrupt
according to the WLAN host target communication and protocol
in different WLAN context and subsystem state. The ath10k snoc
free/request all copy engine interrupt line during wlan subsystem
recovery due to firmware crash or hardware interface down etc.
To avoid the kernel warning and fault due to redundant copy engine
interrupt request/free in different wlan state. Define structure
for copy engine to maintain the stat of copy engine interrupt list
request/free.

commit e434e04110704eb91acfecbd0fb8ca8e2da9c29b upstream.
The tg3_set_eeprom() function correctly initializes the 'start' variable,
but gcc generates a false warning:
drivers/net/ethernet/broadcom/tg3.c: In function 'tg3_set_eeprom':
drivers/net/ethernet/broadcom/tg3.c:12057:4: warning: 'start' may be used uninitialized in this function [-Wmaybe-uninitialized]
I have not come up with a way to restructure the code in a way that
avoids the warning without making it less readable, so this adds an
initialization for the declaration to shut up that warning.

The ath10k snoc driver has two work handlers for the qmi event
processing and serializations of event processing. These two
event work handler must be sync and canceled in driver remove
method to avoid module unload and load failure due to the active
event work handler during device object memory free.
