When read the ACPI data to find out the WGDS, the DATA_SIZE is never
matched.
From the above format, it gives 19 numbers, but our driver is hardcode
as 18.
Fix it to pass then can parse the data into our wgds table.
Then we will see:

commit e13fb9b37cc00616b90df2d620f30345b5ada6ff upstream.
The call to can_put_echo_skb() may result in the skb being freed. The skb
is later used in the call to dev->ops->dev_frame_to_cmd().
This is avoided by moving the call to can_put_echo_skb() after
dev->ops->dev_frame_to_cmd().

[ Upstream commit bfaa9f8553d5c20703781e63f4fc8cb4792f18fd ]
Fixed a condition mistake due to which macvlans unicast
item number 32 was not added in the unicast filter.
The consequence is that when exactly 32 macvlans are created
on NIC, the last created macvlan receives no traffic because
its MAC was not registered in HW.

[ Upstream commit 7a1bb49461b12b2e6332a4d054256835f45203f3 ]
IOMMU fault may occurr on unbind/bind or if_down/if_up sequence.
Although driver disables the rings on down, this is not enough.
Due to internal HW design, during subsequent initialization
NIC sometimes may reuse RX descriptors cache and write to the
host memory from the descriptor cache.
That's get catched by IOMMU on host.
This patch invalidates the descriptor cache in NIC on interface down
to prevent writing to the cached descriptors and to the memory pointed
in those descriptors.

[ Upstream commit ba766b8b99c30ad3c55ed8cf224d1185ecff1476 ]
Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for
outer checksum", 2017-04-06) the i40e driver has not reported support
for IP-in-IP offloads. This likely occurred due to a bad rebase, as the
commit extracts hw_enc_features into its own variable. As part of this
change, it dropped the NETIF_F_FSO_IPXIP flags from the
netdev->hw_enc_features. This was unfortunately not caught during code
review.
Fix this by adding back the missing feature flags.
For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a
("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20),
replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT.
NETIF_F_GSO_IPXIP6 was added in commit bf2d1df39502 ("intel: Add support
for IPv6 IP-in-IP offload", 2016-05-20).

[ Upstream commit d944b46992f8e99b6bdc721e44b02e5ca294fa2b ]
Currently if the driver does a TSO offload the bytecount sent to
netdev_tx_sent_queue will be incorrect. This is because in ice_tso we
overwrite the initial value that we set in ice_tx_map. This creates a
mismatch between the Tx and Tx clean flow. In the Tx clean flow we
calculate the bytecount (called total_bytes) as we clean the
descriptors so the value used in the Tx clean path is correct. Fix this
by using += in ice_tso instead of =. This fixes the mismatch in
bytecount mentioned above.

[ Upstream commit acf3766b36d8e59ecbc307894c6d05703ee48014 ]
The mlx5e channels should be closed before mlx5i_uninit_underlay_qp
puts the QP into RST (reset) state during mlx5i_close. Currently QP
state incorrectly set to RST before channels got deactivated and closed,
since mlx5_post_send request expects QP in RTS (Ready To Send) state.
The fix is to keep QP in RTS state until mlx5e channels get closed
and to reset QP afterwards.
Also this fix is simply correct in order to keep the open/close flow
symmetric, i.e mlx5i_init_underlay_qp() is called first thing at open,
the correct thing to do is to call mlx5i_uninit_underlay_qp() last thing
at close, which is exactly what this patch is doing.

[ Upstream commit 0073c8f72736b423aade8a817587a5f3e4df4ad8 ]
In case of striding RQ, we use MPWRQ (Multi Packet WQE RQ), which means
that WQE (RX descriptor) can be used for many packets and so the WQE is
much bigger than MTU. In virtualization setups where the port mtu can
be larger than the vf mtu, if received packet is bigger than MTU, it
won't be dropped by HW on too small receive WQE. If we use linear SKB in
striding RQ, since each stride has room for mtu size payload and skb
info, an oversized packet can lead to crash for crossing allocated page
boundary upon the call to build_skb. So driver needs to check packet
size and drop it.
Introduce new SW rx counter, rx_oversize_pkts_sw_drop, which counts the
number of packets dropped by the driver for being too large.
As a new field is added to the RQ struct, re-open the channels whenever
this field is being used in datapath (i.e., in the case of linear
Striding RQ).

[ Upstream commit 7cb6a2a2c72c1ed8f42fb01f1a661281b568dead ]
A timing hazard exists when the network interface is stopped that
allows a watchdog timeout to be processed by a separate core in
parallel. This creates the potential for the timeout handler to
wake the queues while the driver is shutting down, or access
registers after their clocks have been removed.
The more common case is that the watchdog timeout will produce a
warning message which doesn't lead to a crash. The chances of this
are greatly increased by the fact that bcm_sysport_netif_stop stops
the transmit queues which can easily precipitate a watchdog time-
out because of stale trans_start data in the queues.
This commit corrects the behavior by ensuring that the watchdog
timeout is disabled before enterring bcm_sysport_netif_stop. There
are currently only two users of the bcm_sysport_netif_stop function:
close and suspend.
The close case already handles the issue by exiting the RUNNING
state before invoking the driver close service.
The suspend case now performs the netif_device_detach to exit the
PRESENT state before the call to bcm_sysport_netif_stop rather than
after it.
These behaviors prevent any future scheduling of the driver timeout
service during the window. The netif_tx_stop_all_queues function
in bcm_sysport_netif_stop is replaced with netif_tx_disable to ensure
synchronization with any transmit or timeout threads that may
already be executing on other cores.
For symmetry, the netif_device_attach call upon resume is moved to
after the call to bcm_sysport_netif_start. Since it wakes the transmit
queues it is not necessary to invoke netif_tx_start_all_queues from
bcm_sysport_netif_start so it is moved into the driver open service.

[ Upstream commit 8ebebcba559a1bfbaec7bbda64feb9870b9c58da ]
When writing packets to a descriptor associated with a combined queue, the
packets should end up on that queue.
Before this change all packets written to any descriptor associated with a
tap interface end up on rx-0, even when the descriptor is associated with a
different queue.
The rx traffic can be generated by either of the following.
1. a simple tap program which spins up multiple queues and writes packets
to each of the file descriptors
2. tx from a qemu vm with a tap multiqueue netdev
The queue for rx traffic can be observed by either of the following (done
on the hypervisor in the qemu case).
1. a simple netmap program which opens and reads from per-queue
descriptors
2. configuring RPS and doing per-cpu captures with rxtxcpu
Alternatively, if you printk() the return value of skb_get_rx_queue() just
before each instance of netif_receive_skb() in tun.c, you will get 65535
for every skb.
Calling skb_record_rx_queue() to set the rx queue to the queue_index fixes
the association between descriptor and rx queue.

commit ea53abfab960909d622ca37bcfb8e1c5378d21cc upstream.
Commit 4d2c0cda07448ea6980f00102dc3964eb25e241c set slave->link to
BOND_LINK_DOWN for 802.3ad bonds whenever invalid speed/duplex values
were read, to fix a problem with slaves getting into weird states, but
in the process, broke tracking of link failures, as going straight to
BOND_LINK_DOWN when a link is indeed down (cable pulled, switch rebooted)
means we broke out of bond_miimon_inspect()'s BOND_LINK_DOWN case because
!link_state was already true, we never incremented commit, and never got
a chance to call bond_miimon_commit(), where slave->link_failure_count
would be incremented. I believe the simple fix here is to mark the slave
as BOND_LINK_FAIL, and let bond_miimon_inspect() transition the link from
_FAIL to either _UP or _DOWN, and in the latter case, we now get proper
incrementing of link_failure_count again.

This also addresses a potential use-after-free (e.g. after probe

commit 3d71c3f1f50cf309bd20659422af549bc784bfff upstream.
The rs_rate_from_ucode_rate() function may return -EINVAL if the rate
is invalid, but none of the callsites check for the error, potentially
making us access arrays with index IWL_RATE_INVALID, which is larger
than the arrays, causing an out-of-bounds access. This will trigger
KASAN warnings, such as the one reported in the bugzilla issue
mentioned below.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=200659

commit 5289976ad887deb07c76df7eecf553c264aeebed upstream.
If the first virtual interface is a station (or an AP with beacons
temporarily disabled), the beacon of the second interface needs to
occupy hardware beacon slot 0.
For some reason the beacon index was incorrectly masked with the
virtual interface beacon mask, which prevents the secondary
interface from sending beacons unless the first one also does.
