In following scenario(diagram), when one thread X running dev_coredumpm()
adds devcd device to the framework which sends uevent notification to
userspace and another thread Y reads this uevent and call to
devcd_data_write() which eventually try to delete the queued timer that
is not initialized/queued yet.
So, debug object reports some warning and in the meantime, timer is
initialized and queued from X path. and from Y path, it gets reinitialized
again and timer->entry.pprev=NULL and try_to_grab_pending() stucks.
To fix this, introduce mutex and a boolean flag to serialize the behaviour.

Pull driver core fixes from Greg KH:
"Here are two tiny driver core fixes for 6.0-rc7 that resolve some
oft-reported problems.
The first is a revert of the "fw_devlink.strict=1" default option that
we keep trying to enable, but we keep finding platforms that this just
breaks everything on. So again, we need it reverted and hopefully it
can be worked on in future releases.
The second is a sysfs file-size bugfix that resolves an issue that
many people are starting to hit as the fix it is fixing also was
backported to stable kernels. The util-linux developers are starting
to get bugreports about sysfs files that contain no data because of
this problem, and this fix which has been in linux-next in the
bitfield tree for a long time, resolves it. I'm submitting it here as
it needs to be merged for 6.0-final, not for 6.1-rc1.
Both of these have been in linux-next with no reported issues, only
reports were that these fixed problems"

"Including fixes from wifi, netfilter and can.
A handful of awaited fixes here - revert of the FEC changes, bluetooth
fix, fixes for iwlwifi spew.
We added a warning in PHY/MDIO code which is triggering on a couple of
platforms in a false-positive-ish way. If we can't iron that out over
the week we'll drop it and re-add for 6.1.
I've added a new "follow up fixes" section for fixes to fixes in
6.0-rcs but it may actually give the false impression that those are
problematic or that more testing time would have caught them. So
likely a one time thing.

- nf_tables_addchain: fix nft_counters_enabled underflow
- ebtables: fix memory leak when blob is malformed
- nf_ct_ftp: fix deadlock when nat rewrite is needed
Current release - regressions:
- Revert "fec: Restart PPS after link state change" and the related
"net: fec: Use a spinlock to guard `fep->ptp_clk_on`"
- Bluetooth: fix HCIGETDEVINFO regression
- wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2

- tcp: read multiple skbs in tcp_read_skb()
- mdio_bus_phy_resume state warning fallout:
- eth: ravb: fix PHY state warning splat during system resume

Current release - new code bugs:
- wifi: iwlwifi: don't spam logs with NSS>2 messages
- eth: mtk_eth_soc: enable XDP support just for MT7986 SoC
Previous releases - regressions:
- bonding: fix NULL deref in bond_rr_gen_slave_id
- wifi: iwlwifi: mark IWLMEI as broken
Previous releases - always broken:
- nf_conntrack helpers:
- irc: tighten matching on DCC message

When reading the timestamp is required bnxt_tx_int() hands
over the ownership of the completed skb to the PTP worker.
The skb should not be used afterwards, as the worker may
run before the rest of our code and free the skb, leading
to a use-after-free.
Since dev_kfree_skb_any() accepts NULL make the loss of
ownership more obvious and set skb to NULL.

In prestera_port_sfp_bind(), there are two refcounting bugs:
(1) we should call of_node_get() before of_find_node_by_name() as
it will automaitcally decrease the refcount of 'from' argument;
(2) we should call of_node_put() for the break of the iteration
for_each_child_of_node() as it will automatically increase and
decrease the 'child'.

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.
To reproduce this problem, ping a HME with a payload size between 17 and
214
$ ping -s 17 <hme_address>
which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.

Fix a NULL dereference of the struct bonding.rr_tx_counter member because
if a bond is initially created with an initial mode != zero (Round Robin)
the memory required for the counter is never created and when the mode is
changed there is never any attempt to verify the memory is allocated upon
switching modes.

We currently check the MokSBState variable to decide whether we should
treat UEFI secure boot as being disabled, even if the firmware thinks
otherwise. This is used by shim to indicate that it is not checking
signatures on boot images. In the kernel, we use this to relax lockdown
policies.
However, in cases where shim is not even being used, we don't want this
variable to interfere with lockdown, given that the variable may be
non-volatile and therefore persist across a reboot. This means setting
it once will persistently disable lockdown checks on a given system.
So switch to the mirrored version of this variable, called MokSBStateRT,
which is supposed to be volatile, and this is something we can check.

When booting the x86 kernel via EFI using the LoadImage/StartImage boot
services [as opposed to the deprecated EFI handover protocol], the setup
header is taken from the image directly, and given that EFI's LoadImage
has no Linux/x86 specific knowledge regarding struct bootparams or
struct setup_header, any absolute addresses in the setup header must
originate from the file and not from a prior loading stage.
Since we cannot generally predict where LoadImage() decides to load an
image (*), such absolute addresses must be treated as suspect: even if a
prior boot stage intended to make them point somewhere inside the
[signed] image, there is no way to validate that, and if they point at
an arbitrary location in memory, the setup_data nodes will not be
covered by any signatures or TPM measurements either, and could be made
to contain an arbitrary sequence of SETUP_xxx nodes, which could
interfere quite badly with the early x86 boot sequence.
(*) Note that, while LoadImage() does take a buffer/size tuple in
addition to a device path, which can be used to provide the image
contents directly, it will re-allocate such images, as the memory
footprint of an image is generally larger than the PE/COFF file
representation.

when assigning an XDP TX queue to every CPU is not possible,
so they have to be shared.
However, in the XDP transmit handler ice_xdp_xmit(), an error was

As the comment right before the mtk_dsi_stop() call advises,
mtk_dsi_stop() should only be called after
mtk_drm_crtc_atomic_disable(). That's because that function calls
drm_crtc_wait_one_vblank(), which requires the vblank irq to be enabled.
Previously mtk_dsi_stop(), being in mtk_dsi_poweroff() and guarded by a
refcount, would only be called at the end of
mtk_drm_crtc_atomic_disable(), through the call to mtk_crtc_ddp_hw_fini().
Commit cde7e2e35c28 ("drm/mediatek: Separate poweron/poweroff from
enable/disable and define new funcs") moved the mtk_dsi_stop() call to
mtk_output_dsi_disable(), causing it to be called before
mtk_drm_crtc_atomic_disable(), and consequently generating vblank
timeout warnings during suspend.
Move the mtk_dsi_stop() call back to mtk_dsi_poweroff() so that we have
a working vblank irq during mtk_drm_crtc_atomic_disable() and stop
getting vblank timeout warnings.

[Why]
During hot plug of specific 5K tiled display, sometimes both the tiles
are not synchronized resulting in distortion. The reason is that otgs of
both the tiles goes out of sync when otg workaround (dcnxxx_disable_otg_wa)
is applied for bandwidth optimization. The otg workaround reenables otg
but otg synchronization context is not reset and hence dc_trigger_sync()
does not resynchronize otg again.

context for the disabled pipe and its slave pipes when otg workaround is

[Why]
DC makes use of layer_index (zpos) when picking the HW plane to enable
HW cursor on. However, some compositors will not attach zpos information
to each DRM plane. Consequently, in amdgpu, we default layer_index to 0
and do not update it.
This causes said DC logic to enable HW cursor on all planes of the same
layer_index, which manifests as a double cursor issue if one of the
planes is scaled (and hence scaling the cursor as well).
[How]
Use DRM core helpers to calculate a normalized_zpos value for each
drm_plane_state under each crtc, within the atomic state.
This helper will first consider existing zpos values, and if
identical/unset, fallback to plane ID ordering.
The normalized_zpos is then passed to dc_plane_info during atomic check
for later use by the cursor logic.

This patch updates the PTE flags when translate further (TF) is
enabled:
- With translate_further enabled, invalid PTEs can be 0. Reading
consecutive invalid PTEs as 0 is considered a fault. To prevent
this, ensure invalid PTEs have at least 1 bit set.
- The current invalid PTE flags settings to translate a retry fault
into a no-retry fault, doesn't work with TF enabled. As a result,

====================
pull-request: can 2022-09-21
The 1st patch is by me, targets the flexcan driver and fixes a
potential system hang on single core systems under high CAN packet
rate.
The next 2 patches are also by me and target the gs_usb driver. A
potential race condition during the ndo_open callback as well as the
return value if the ethtool identify feature is not supported are
fixed.
