[ Upstream commit 028e0838 ]

The UCR4_OREN should be disabled before disabling the uart receiver in
.stop_rx() instead of in the .shutdown().

Otherwise, if we have the overrun error during the receiver disable
process, the overrun interrupt will keep trigging until we disable the
OREN interrupt in the .shutdown(), because the ORE status can only be
cleared when read the rx FIFO or reset the controller.  Although the
called time between the receiver disable and OREN disable in .shutdown()
is very short, there is still the risk of endless interrupt during this
short period of time. So here change to disable OREN before the receiver
been disabled in .stop_rx().

[ Upstream commit 11632d4a ]

In the configuration used by the b850v3, the STDP2690 is used to read EDID
data whilst it's the STDP4028 which can detect when monitors are connected.

This can result in problems at boot with monitors connected when the
STDP4028 is probed first, a monitor is detected and an attempt is made to
read the EDID data before the STDP2690 has probed:

[ Upstream commit c1020d3c ]

On an arm64 platform with the Spectrum ASIC, after loading and executing
a new kernel via kexec, the following trace [1] is observed. This seems
to be caused by the fact that the device is not properly shutdown before
executing the new kernel.

Fix this by implementing a shutdown method which mirrors the remove
method, as recommended by the kexec maintainer [2][3].

[ Upstream commit b0100bce ]

Since commit 4b563a06 ("ARM: imx: Remove imx21 support"), the config
DEBUG_IMX21_IMX27_UART is really only debug support for IMX27.

So, rename this option to DEBUG_IMX27_UART and adjust dependencies in
Kconfig and rename the definitions to IMX27 as further clean-up.

This issue was discovered with ./scripts/checkkconfigsymbols.py, which
reported that DEBUG_IMX21_IMX27_UART depends on the non-existing config
SOC_IMX21.

--------------------------------

[ Upstream commit b1320303 ]

A out-of-bounds bug can be triggered by an interrupt, the reason for
this bug is the lack of checking of register values.

In flexcop_pci_isr, the driver reads value from a register and uses it as
a dma address. Finally, this address will be passed to the count parameter
of find_next_packet. If this value is larger than the size of dma, the
index of buffer will be out-of-bounds.

Fix this by adding a check after reading the value of the register.

The following KASAN report reveals it:

[ Upstream commit c76ef96f ]

Function fs endpoint file operations are synchronized via an interruptible
mutex wait. However we see threads that do ep file operations concurrently
are getting blocked for the mutex lock in __fdget_pos(). This is an
uninterruptible wait and we see hung task warnings and kernel panic
if hung_task_panic systcl is enabled if host does not send/receive
the data for long time.

The reason for threads getting blocked in __fdget_pos() is due to
the file position protection introduced by the commit 9c225f26
("vfs: atomic f_pos accesses as per POSIX"). Since function fs
endpoint files does not have the notion of the file position, switch
to the stream mode. This will bypass the file position mutex and
threads will be blocked in interruptible state for the function fs
mutex.

It should not affects user space as we are only changing the task state
changes the task state from UNINTERRUPTIBLE to INTERRUPTIBLE while waiting
for the USB transfers to be finished. However there is a slight change to
the O_NONBLOCK behavior. Earlier threads that are using O_NONBLOCK are also
getting blocked inside fdget_pos(). Now they reach to function fs and error
code is returned. The non blocking behavior is actually honoured now.

[ Upstream commit 273703eb ]

Commit 31582373 ("ath11k: Change number of TCL rings to one for
QCA6390") avoids initializing the other entries of dp->tx_ring cause
the corresponding TX rings on QCA6390/WCN6855 are not used, but leaves
those ring masks in ath11k_hw_ring_mask_qca6390.tx unchanged. Normally
this is OK because we will only get interrupts from the first TX ring
on these chips and thus only the first entry of dp->tx_ring is involved.

In case of one MSI vector, all DP rings share the same IRQ. For each
interrupt, all rings have to be checked, which means the other entries
of dp->tx_ring are involved. However since they are not initialized,
system crashes.

Fix this issue by simply removing those ring masks.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ebe9c978d9e777f6e9090834e2b90451e5bdb3ba

--------------------------------

[ Upstream commit 9057d6c2 ]

Currently, creating a batman-adv interface in an unprivileged LXD
container and attaching secondary interfaces to it with "ip" or "batctl"
works fine. However all batctl debug and configuration commands
fail:

  root@container:~# batctl originators
  Error received: Operation not permitted
  root@container:~# batctl orig_interval
  1000
  root@container:~# batctl orig_interval 2000
  root@container:~# batctl orig_interval
  1000

To fix this change the generic netlink permissions from GENL_ADMIN_PERM
to GENL_UNS_ADMIN_PERM. This way a batman-adv interface is fully
maintainable as root from within a user namespace, from an unprivileged
container.

All except one batman-adv netlink setting are per interface and do not
leak information or change settings from the host system and are
therefore save to retrieve or modify as root from within an unprivileged
container.

"batctl routing_algo" / BATADV_CMD_GET_ROUTING_ALGOS is the only
exception: It provides the batman-adv kernel module wide default routing
algorithm. However it is read-only from netlink and an unprivileged
container is still not allowed to modify
/sys/module/batman_adv/parameters/routing_algo. Instead it is advised to
use the newly introduced "batctl if create routing_algo RA_NAME" /
IFLA_BATADV_ALGO_NAME to set the routing algorithm on interface
creation, which already works fine in an unprivileged container.

Not doing so fixes the exposure always being reset to the value from
the res->regs array after a set_fmt().

[ Upstream commit 2c45e343 ]

The atomisp driver originally used the s_parm command to
initialize the run_mode type to the driver. So, before start
setting up the streaming, s_parm should be called.

So, even having 5 "normal" video devices, one meant to be used
for each type, the run_mode was actually selected when
s_parm is called.

Without setting the run mode, applications that don't call
VIDIOC_SET_PARM with a custom atomisp parameters won't work, as
the pipeline won't be set:

	atomisp-isp2 0000:00:03.0: can't create streams
	atomisp-isp2 0000:00:03.0: __get_frame_info 1600x1200 (padded to 0) returned -22

However, commit 8a7c5594 ("media: v4l2-ioctl: clear fields in s_parm")
broke support for it, with a good reason, as drivers shoudn't be
extending the API for their own purposes.

So, as an step to allow generic apps to use this driver, put
the device's run_mode in preview after open.

After this patch, using v4l2grab starts to work on preview
mode (/dev/video2):

	$ v4l2grab -f YUYV -x 1600 -y 1200 -d /dev/video2 -n 1 -u
	$ feh out000.pnm

So, let's just setup the default run_mode that each video devnode
should assume, setting it at open() time.

bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9

[ Upstream commit 1d2271d2 ]

There have been reports of the WFI timing out on some boards, and a
patch was proposed to just remove it.  This stuff is rather fragile,
and I believe the WFI might be needed with our FW prior to GM200.

However, we probably should not be touching PMU during init on GPUs
where we depend on NVIDIA FW, outside of limited circumstances, so
this should be a somewhat safer change that achieves the desired
result.

--------------------------------

[ Upstream commit 3f2532d6 ]

The current ELD handling takes the internal connector ELD buffer and
shares it to the I2S and AHB sub-driver.

But with DRM_BRIDGE_ATTACH_NO_CONNECTOR, the connector is created
elsewhere (or not), and an eventual connector is known only
if the bridge chain up to a connector is enabled.

The current dw-hdmi code gets the current connector from
atomic_enable() so use the already stored connector pointer and
replace the buffer pointer with a callback returning the current
connector ELD buffer.

Since a connector is not always available, either pass an empty
ELD to the alsa HDMI driver or don't call snd_pcm_hw_constraint_eld()
in AHB driver.

Unexpected WDCMSG_TARGET_START replay can lead to null-ptr-deref
when ar->tx_cmd->odata is NULL. The patch adds a null check to
prevent such case.

I found the bug using a custome USBFuzz port. It's a research work
to fuzz USB stack/drivers. I modified it to fuzz ath9k driver only,
providing hand-crafted usb descriptors to QEMU.

After fixing the code (fourth byte in usb packet) to WDCMSG_TARGET_START,
I got the null-ptr-deref bug. I believe the bug is triggerable whenever
cmd->odata is NULL. After patching, I tested with the same input and no
longer see the KASAN report.

This was NOT tested on a real device.

The issue is that we received a DLM message for a user lock but the
destination lock is a kernel lock. Note that the address which is trying
to derefence is 00000000deadbeef, which is in a kernel lock
lkb->lkb_astparam, this field should never be derefenced by the DLM
kernel stack. In case of a user lock lkb->lkb_astparam is lkb->lkb_ua
(memory is shared by a union field). The struct lkb_ua will be handled
by the DLM kernel stack but on a kernel lock it will contain invalid
data and ends in most likely crashing the kernel.

It can be reproduced with two cluster nodes.

node 2:
dlm_tool join test
echo "862 fooobaar 1 2 1" > /sys/kernel/debug/dlm/test_locks
echo "862 3 1" > /sys/kernel/debug/dlm/test_waiters

node 1:
dlm_tool join test

python:
foo = DLM(h_cmd=3, o_nextcmd=1, h_nodeid=1, h_lockspace=0x77222027, \
          m_type=7, m_flags=0x1, m_remid=0x862, m_result=0xFFFEFFFE)

[ Upstream commit 6f03055d ]

The MIPS BMC63XX subarch does not provide/support clk_set_parent().
This causes build errors in a few drivers, so add a simple implementation
of that function so that callers of it will build without errors.

Fixes these build errors:

ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined!
ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!

[ Upstream commit 01f68f06 ]

Currently, the STM32 LP Timer counter driver registers into both IIO and
counter subsystems, which is redundant.

Remove the IIO counter ABI and IIO registration from the STM32 LP Timer
counter driver since it's been superseded by the Counter subsystem
as discussed in [1].

Keep only the counter subsystem related part.
Move a part of the ABI documentation into a driver comment.

This also removes a duplicate ABI warning
