This patch fixes an off-by-one error in strncpy size argument in
drivers/net/ethernet/samsung/sxgbe/sxgbe_main.c. The issue is that in:
strncmp(opt, "eee_timer:", 6)
the passed string literal: "eee_timer:" has 10 bytes (without the NULL
byte) and the passed size argument is 6. As a result, the logic will
also accept other, malformed strings, e.g. "eee_tiXXX:".
This bug doesn't seem to have any security impact since its present in
module's cmdline parsing code.

The NCM specification defines two formats of transfer blocks: with 16-bit
fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is
implemented.
This patch adds the support of NTB-32. The motivation behind this is that
some devices such as E5785 or E5885 from the current generation of Huawei
LTE routers do not support NTB-16. The previous generations of Huawei
devices are also use NTB-32 by default.
Also this patch enables NTB-32 by default for Huawei devices.
During the 2019 ValdikSS made five attempts to contact Huawei to add the
NTB-16 support to their router firmware, but they were unsuccessful.

Reverted commit "2baecda bareudp: remove unnecessary udp_encap_enable() in

An explicit call to udp_encap_enable is needed as the setup_udp_tunnel_sock
does not call udp_encap_enable if the if the socket is of type v6.
Bareudp device uses v6 socket to receive v4 & v6 traffic

Since the semaphore fence may be signaled from inside an interrupt
handler from inside a request holding its request->lock, we cannot then
enter into the engine->active.lock for processing the semaphore priority
bump as we may traverse our call tree and end up on another held

we know that the last element is the last request in the execution queue,

Commit c3b5a8430daad ("drm/i915/gvt: Enable gfx virtualiztion for CFL")
added the support on CFL. The vgpu emulation hotplug support on CFL was
supposed to be included in that patch. Without the vgpu emulation
hotplug support, the dma-buf based display gives us a blur face.
So fix this issue by adding the vgpu emulation hotplug support on CFL.

- Align the i.MX SC message structs causing warnings from KASan.
- Balance the kref in pinctrl hogs so they are actually free:d when
removing a pin control module. We haven't seen it before as people
don't use modules for pin control that much, I think.
- Add a missing call to pinctrl_unregister_mappings() another memory
leak when using modules.

This does three inter-related things to clarify the usage of the
platform device dma_mask field. In the process, fix the bug introduced
by cdfee5623290 ("driver core: initialize a default DMA mask for
platform device") that caused Artem Tashkinov's laptop to not boot with
newer Fedora kernels.
This does:
- First off, rename the field to "platform_dma_mask" to make it
greppable.
We have way too many different random fields called "dma_mask" in
various data structures, where some of them are actual masks, and
some of them are just pointers to the mask. And the structures all
have pointers to each other, or embed each other inside themselves,
and "pdev" sometimes means "platform device" and sometimes it means
"PCI device".
So to make it clear in the code when you actually use this new field,
give it a unique name (it really should be something even more unique
like "platform_device_dma_mask", since it's per platform device, not
per platform, but that gets old really fast, and this is unique
enough in context).
To further clarify when the field gets used, initialize it when we
actually start using it with the default value.
- Then, use this field instead of the random one-off allocation in
platform_device_register_full() that is now unnecessary since we now
already have a perfectly fine allocation for it in the platform
device structure.
- The above then allows us to fix the actual bug, where the error path
of platform_device_register_full() would unconditionally free the
platform device DMA allocation with 'kfree()'.
That kfree() was dont regardless of whether the allocation had been
done earlier with the (now removed) kmalloc, or whether
setup_pdev_dma_masks() had already been used and the dma_mask pointer
pointed to the mask that was part of the platform device.
It seems most people never triggered the error path, or only triggered
it from a call chain that set an explicit pdevinfo->dma_mask value (and
thus caused the unnecessary allocation that was "cleaned up" in the
error path) before calling platform_device_register_full().
Robin Murphy points out that in Artem's case the wdat_wdt driver failed
in platform_device_add(), and that was the one that had called
platform_device_register_full() with pdevinfo.dma_mask = 0, and would
have caused that kfree() of pdev.dma_mask corrupting the heap.
A later unrelated kmalloc() then oopsed due to the heap corruption.

Jeff Kirsher says:
====================
100GbE Intel Wired LAN Driver Updates 2020-03-10
This series contains updates to ice and iavf drivers.
Cleaned up unnecessary parenthesis, which was pointed out by Sergei
Shtylyov.
Mitch updates the iavf and ice drivers to expand the limitation on the
number of queues that the driver can support to account for the newer
800-series capabilities.
Brett cleans up the error messages for both SR-IOV and non SR-IOV use
cases. Fixed the logic when the ice driver is removed and a bare-metal
VF is passing traffic, which was causing a transmit hang on the VF.
Updated the ice driver to display "Link detected" field via ethtool,
when the driver is in safe mode. Updated ice driver to properly set
VLAN pruning when transmit anti-spoof is off.
Avinash fixed a corner case in DCB, when switching from IEEE to CEE
mode, the DCBX mode does not get properly updated.
Dave updates the logic when switching from software DCB to firmware DCB
to renegotiate DCBX to ensure the firmware agent has up to date
information about the DCB settings of the link partner.
Lukasz increases the PF's mailbox receive queue size to the maximum to
prevent potential bottleneck or slow down occurring from the PF's
mailbox receive queue being full.
Bruce updates the ice driver to use strscpy() instead of strlcpy().
Cleaned up variable names that were not very descriptive with names that
had more meaning.
Anirudh replaces the use of ENOTSUPP with EOPNOTSUPP in the ice driver.
Jake fixed up a function header comment to properly reflect the variable
size and use.
v2: Dropped patch 5 of the original series, where Tony added tunnel
offload support. Based on community feedback, the patch needed
changes, so giving Tony additional time to work on those changes and
not hold up the remaining changes in the series.

When qeth's napi poll code fails to refill an entirely empty RX ring, it
kicks off buffer_reclaim_work to try again later.
Make sure that this worker is cancelled when setting the qeth device
offline. Otherwise a RX refill action can unexpectedly end up running
concurrently to bigger re-configurations (eg. resizing the buffer pool),
without any locking.

qeth_init_qdio_queues() fills the RX ring with an initial set of
RX buffers. If qeth_init_input_buffer() fails to back one of the RX
buffers with memory, we need to bail out and report the error.

When an OSA device in prio-queue setup is reduced to 1 TX queue due to
HW restrictions, we reset its the default_out_queue to 0.
In the old code this was needed so that qeth_get_priority_queue() gets
the queue selection right. But with proper multiqueue support we already
reduced dev->real_num_tx_queues to 1, and so the stack puts all traffic
on txq 0 without even calling .ndo_select_queue.
Thus we can preserve the user's configuration, and apply it if the OSA
device later re-gains support for multiple TX queues.

flow_action_hw_stats_types_check()
The intention of this helper was to allow driver to specify one type
that it supports, so not only "any" value would pass. So make the API
more strict and allow driver to pass only 1 bit that is going
to be checked.

The ibmvnic driver does not check the device state when the device
is removed. If the device is removed while a device reset is being
processed, the remove may free structures needed by the reset,
causing an oops.
Fix this by checking the device state before processing device remove.

Hardware timestamping support (PTP) on Rx requires extended
buffer descriptors, double the size of normal Rx descriptors.
On the current controller revision only the timestamping offload
requires extended Rx descriptors.
Since Rx timestamping can be turned on/off at runtime, make Rx ring
allocation configurable at runtime too. As a result, the static
config option FSL_ENETC_HW_TIMESTAMPING can be dropped and the
extended descriptors can be used only when Rx timestamping gets
activated.
The extension has the same size as the base descriptor, making
the descriptor iterators easy to update for the extended case.
