The HDaudio stream allocation is done first, and in a second step the
LOSIDV parameter is programmed for the multi-link used by a codec.
This leads to a possible stream_tag leak, e.g. if a DisplayAudio link
is not used. This would happen when a non-Intel graphics card is used
and userspace unconditionally uses the Intel Display Audio PCMs without
checking if they are connected to a receiver with jack controls.
We should first check that there is a valid multi-link entry to
configure before allocating a stream_tag. This change aligns the
dma_assign and dma_cleanup phases.

ASoC: Fix for v6.2
One non-urgent fix for v6.2, this could possibly wait till the
merge window.
Cited commit changed devlink to register its netdev notifier block on
the global netdev notifier chain instead of on the per network namespace
one.
However, when changing the network namespace of the devlink instance,
devlink still tries to unregister its notifier block from the chain of
the old namespace and register it on the chain of the new namespace.
This results in corruption of the notifier chains, as the same notifier
block is registered on two different chains: The global one and the per
network namespace one. In turn, this causes other problems such as the
inability to dismantle namespaces due to netdev reference count issues.
Fix by preventing devlink from moving its notifier block between
namespaces.
Reproducer:
# echo "10 1" > /sys/bus/netdevsim/new_device
# ip netns add test123
# devlink dev reload netdevsim/netdevsim10 netns test123
# ip netns del test123
[ 71.935619] unregister_netdevice: waiting for lo to become free. Usage count = 2
[ 71.938348] leaked reference.

Commit a97f8783a9 ("igb: unbreak I2C bit-banging on i350") introduced
code to change I2C settings to bit banging unconditionally.
However, this patch introduced a regression: On an Intel S2600CWR
Server Board with three NICs:
- 1x dual-port copper
Intel I350 Gigabit Network Connection [8086:1521] (rev 01)
fw 1.63, 0x80000dda
- 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ
Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01)
fw 1.52.0
the SFP NICs no longer get link at all. Reverting commit a97f8783a9
or switching to the Intel out-of-tree driver both fix the problem.
Per the igb out-of-tree driver, I2C bit banging on i350 depends on
support for an external thermal sensor (ETS). However, commit
a97f8783a9 added bit banging unconditionally. Additionally, the
out-of-tree driver always calls init_thermal_sensor_thresh on probe,
while our driver only calls init_thermal_sensor_thresh only in
igb_reset(), and only if an ETS is present, ignoring the internal
thermal sensor. The affected SFPs don't provide an ETS. Per Intel,
the behaviour is a result of i350 firmware requirements.
This patch fixes the problem by aligning the behaviour to the
out-of-tree driver:
- split igb_init_i2c() into two functions:
- igb_init_i2c() only performs the basic I2C initialization.
- igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set
and enables bit-banging.
- igb_probe() only calls igb_set_i2c_bb() if an ETS is present.
- igb_probe() calls init_thermal_sensor_thresh() unconditionally.
- igb_reset() aligns its behaviour to igb_probe(), i. e., call
igb_set_i2c_bb() if an ETS is present and call
init_thermal_sensor_thresh() unconditionally.

Just after the fix to TASK_COMM_LEN not converted to its value in
trace_events was pulled, the kernel test robot reported that the
helper function trace_define_field_ext() added to that change was only
used in the file it was defined in but was not declared static.
Make it a local function"

tracing: Make trace_define_field_ext() static
This fixes a regression in mediation of getattr when old policy built
under an older ABI is loaded and mapped to internal permissions.
The regression does not occur for all getattr permission requests,
only appearing if state zero is the final state in the permission
lookup. This is because despite the first state (index 0) being
guaranteed to not have permissions in both newer and older permission
formats, it may have to carry permissions that were not mediated as
part of an older policy. These backward compat permissions are
mapped here to avoid special casing the mediation code paths.
Since the mapping code already takes into account backwards compat
permission from older formats it can be applied to state 0 to fix
the regression.

The commit 1796f808e4 ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.
However for some devices there is a bug, that is causing the touchpad to
instantly wake up the device again once it gets deactivated. The root cause
is still under investigation (see Link tag).
To workaround this problem for the time being, introduce a quirk for this
model that will prevent the wakeup capability for being set for GPIO 16.

If a non-root cgroup gets removed when there is a thread that registered
trigger and is polling on a pressure file within the cgroup, the polling
waitqueue gets freed in the following path:
do_rmdir
cgroup_rmdir
kernfs_drain_open_files
cgroup_file_release
cgroup_pressure_release
psi_trigger_destroy
However, the polling thread still has a reference to the pressure file and
will access the freed waitqueue when the file is closed or upon exit:
fput
ep_eventpoll_release
ep_free
ep_remove_wait_queue
remove_wait_queue
This results in use-after-free as pasted below.
The fundamental problem here is that cgroup_file_release() (and
consequently waitqueue's lifetime) is not tied to the file's real lifetime.
Using wake_up_pollfree() here might be less than ideal, but it is in line
with the comment at commit 42288cb44c ("wait: add wake_up_pollfree()")
since the waitqueue's lifetime is not tied to file's one and can be
considered as another special case. While this would be fixable by somehow
making cgroup_file_release() be tied to the fput(), it would require
sizable refactoring at cgroups or higher layer which might be more
justifiable if we identify more cases like this.

lianhui reports that when MPLS fails to register the sysctl table
under new location (during device rename) the old pointers won't
get overwritten and may be freed again (double free).
Handle this gracefully. The best option would be unregistering
the MPLS from the device completely on failure, but unfortunately
mpls_ifdown() can fail. So failing fully is also unreliable.
Another option is to register the new table first then only
remove old one if the new one succeeds. That requires more
code, changes order of notifications and two tables may be
visible at the same time.
sysctl point is not used in the rest of the code - set to NULL
on failures and skip unregister if already NULL.

It is because commit a41dad905e ("iov_iter: saner checks for attempt
to copy to/from iterator") has introduced sanity check for copying
from/to iov iterator. Lacking of copy direction from the iterator

This commit fixes this issue by initializing the iov iterator with

v3: Fix vmw_user_bo_lookup which was also dropping the gem reference
before the kernel was done with buffer depending on userspace doing
the right thing. Same bug, different spot.
It is possible for userspace to predict the next buffer handle and
to destroy the buffer while it's still used by the kernel. Delay
dropping the internal reference on the buffers until kernel is done
with them.
Instead of immediately dropping the gem reference in vmw_user_bo_lookup
and vmw_gem_object_create_with_handle let the callers decide when they're
ready give the control back to userspace.
Also fixes the second usage of vmw_gem_object_create_with_handle in
vmwgfx_surface.c which wasn't grabbing an explicit reference
to the gem object which could have been destroyed by the userspace
on the owning surface at any point.

ttm_bo_init_reserved on failure puts the buffer object back which
causes it to be deleted, but kfree was still being called on the same
buffer in vmw_bo_create leading to a double free.
After the double free the vmw_gem_object_create_with_handle was
setting the gem function objects before checking the return status
of vmw_bo_create leading to null pointer access.
Fix the entire path by relaying on ttm_bo_init_reserved to delete the
buffer objects on failure and making sure the return status is checked
before setting the gem function objects on the buffer object.

The UNSLICE_UNIT_LEVEL_CLKGATE register programmed by this workaround
has 'BUS' style reset, indicating that it does not lose its value on
engine resets. Furthermore, this register is part of the GT forcewake
domain rather than the RENDER domain, so it should not be impacted by
RCS engine resets. As such, we should implement this on the GT
workaround list rather than an engine list.
