c793f8ea15 ice: Fix disabling Rx VLAN filtering with port VLAN enabled
If the user turns on the vf-true-promiscuous-support flag, then Rx VLAN
filtering will be disabled if the VF requests to enable promiscuous
mode. When the VF is in a port VLAN, this is the incorrect behavior
because it will allow the VF to receive traffic outside of its port VLAN
domain. Fortunately this only resulted in the VF(s) receiving broadcast
traffic outside of the VLAN domain because all of the VLAN promiscuous
rules are based on the port VLAN ID. Fix this by setting the
.disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on
the VF.

Also, make sure to make this fix for both Single VLAN Mode and Double
VLAN Mode enabled devices.

4d159f7884 ice: Do not use WQ_MEM_RECLAIM flag for workqueue
When both ice and the irdma driver are loaded, a warning in
check_flush_dependency is being triggered. This is due to ice driver
workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the
workqueue will be involved in the kernel's memory reclamation flow.
Since it is not, there is no need for the ice driver's WQ to have this
flag set so remove it.

Example trace:

6afaed53cc btrfs: simplify update of last_dir_index_offset when logging a directory
When logging a directory, we always set the inode's last_dir_index_offset
to the offset of the last dir index item we found. This is using an extra
field in the log context structure, and it makes more sense to update it
only after we insert dir index items, and we could directly update the
inode's last_dir_index_offset field instead.

So make this simpler by updating the inode's last_dir_index_offset only
when we actually insert dir index keys in the log tree, and getting rid
of the last_dir_item_offset field in the log context structure.

05ecb68070 cgroup fixes for v6.2-rc7
During v6.2 cycle, there were a series of changes to task cpu affinity
 handling which fixed cpuset inadvertently clobbering user-configured
 affinity masks. Unfortunately, they broke the affinity handling on hybrid
 heterogeneous CPUs which have cores that can execute both 64 and 32bit along
 with cores that can only execute 32bit code.
 
 This late pull request contains two fix patches for the above issue. While
 reverting the changes that caused the regression is definitely an option,
 the origial patches do improve how cpuset behave signficantly in some cases
 and the fixes seem fairly safe, so I think it'd be better to try to fix them
 first.

7a2127e66a cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task
set_cpus_allowed_ptr() will fail with -EINVAL if the requested
affinity mask is not a subset of the task_cpu_possible_mask() for the
task being updated. Consequently, on a heterogeneous system with cpusets
spanning the different CPU types, updates to the cgroup hierarchy can
silently fail to update task affinities when the effective affinity
mask for the cpuset is expanded.

For example, consider an arm64 system with 4 CPUs, where CPUs 2-3 are
the only cores capable of executing 32-bit tasks. Attaching a 32-bit
task to a cpuset containing CPUs 0-2 will correctly affine the task to
CPU 2. Extending the cpuset to CPUs 0-3, however, will fail to extend
the affinity mask of the 32-bit task because update_tasks_cpumask() will
pass the full 0-3 mask to set_cpus_allowed_ptr().

Extend update_tasks_cpumask() to take a temporary 'cpumask' paramater
and use it to mask the 'effective_cpus' mask with the possible mask for
each task being updated.

3fb906e7fa cgroup/cpuset: Don't filter offline CPUs in cpuset_cpus_allowed() for top cpuset tasks
Since commit 8f9ea86fdf ("sched: Always preserve the user
requested cpumask"), relax_compatible_cpus_allowed_ptr() is calling
__sched_setaffinity() unconditionally. This helps to expose a bug in
the current cpuset hotplug code where the cpumasks of the tasks in
the top cpuset are not updated at all when some CPUs become online or
offline. It is likely caused by the fact that some of the tasks in the
top cpuset, like percpu kthreads, cannot have their cpu affinity changed.

One way to reproduce this as suggested by Peter is:
 - boot machine
 - offline all CPUs except one
 - taskset -p ffffffff $$
 - online all CPUs

Fix this by allowing cpuset_cpus_allowed() to return a wider mask that
includes offline CPUs for those tasks that are in the top cpuset. For
tasks not in the top cpuset, the old rule applies and only online CPUs
will be returned in the mask since hotplug events will update their
cpumasks accordingly.

Fixes: 8f9ea86fdf ("sched: Always preserve the user requested cpumask")

8f20660f05 drm/virtio: exbuf->fence_fd unmodified on interrupted wait
An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned
to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to
retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1,
making the retry attempt fail at sync_file_get_fence().

The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the
passed value for exbuf->fence_fd when returning anything besides a
successful result from the ioctl.

db370a8b9f rtmutex: Ensure that the top waiter is always woken up
Let L1 and L2 be two spinlocks.

Let T1 be a task holding L1 and blocked on L2. T1, currently, is the top
waiter of L2.

Let T2 be the task holding L2.

Let T3 be a task trying to acquire L1.

The following events will lead to a state in which the wait queue of L2
isn't empty, but no task actually holds the lock.

T1                T2                                  T3

T1 wakes up
T1 != top_waiter(L2)
schedule_rtlock()

If the deadline of T1 is updated before the call to update_prio(), and the
new deadline is greater than the deadline of the second top waiter, then
after the requeue, T1 is no longer the top waiter, and the wrong task is
woken up which will then go back to sleep because it is not the top waiter.

This can be reproduced in PREEMPT_RT with stress-ng:

while true; do
    stress-ng --sched deadline --sched-period 1000000000 \
    	    --sched-runtime 800000000 --sched-deadline \
    	    1000000000 --mmapfork 23 -t 20
done

A similar issue was pointed out by Thomas versus the cases where the top
waiter drops out early due to a signal or timeout, which is a general issue
for all regular rtmutex use cases, e.g. futex.

The problematic code is in rt_mutex_adjust_prio_chain():

    	// Save the top waiter before dequeue/enqueue
	prerequeue_top_waiter = rt_mutex_top_waiter(lock);

	rt_mutex_dequeue(lock, waiter);
	waiter_update_prio(waiter, task);
	rt_mutex_enqueue(lock, waiter);

	// Lock has no owner?
	if (!rt_mutex_owner(lock)) {
	   	// Top waiter changed		      			   
  ---->		if (prerequeue_top_waiter != rt_mutex_top_waiter(lock))
  ---->			wake_up_state(waiter->task, waiter->wake_state);

This only takes the case into account where @waiter is the new top waiter
due to the requeue operation.

But it fails to handle the case where @waiter is not longer the top
waiter due to the requeue operation.

Ensure that the new top waiter is woken up so in all cases so it can take
over the ownerless lock.

251e8c5b1b drm/i915: Move fd_install after last use of fence
Because eb_composite_fence_create() drops the fence_array reference

90d5e8301a drm/i915: Don't do the WM0->WM1 copy w/a if WM1 is already enabled
Due to a workaround we have to make sure the WM1 watermarks block/lines
values are sensible even when WM1 is disabled. To that end we copy those
values from WM0.

However since we now keep each wm level enabled on a per-plane basis
it doesn't seem necessary to do that copy when we already have an
enabled WM1 on the current plane. That is, we might be in a situation
where another plane can only do WM0 (and thus needs the copy) but
the current plane's WM1 is still perfectly valid (ie. fits into the
current DDB allocation).

Skipping the copy could avoid reprogramming the plane's registers
needlessly in some cases.

The DAPM callback doesn't guarantee that the bit-clock is running, so
the work was moved instead to the trigger callback. Unfortunately this
callback runs in atomic context, and the setup code needs to do I2C
transactions.

Here we use a work_struct to kick off the setup in a thread instead.

It was reported that commit b300667b33 ("HID: amd_sfh: Disable the

x360.

Before this commit 3 sensors were reported, but they were not actually
functional.  After this commit the sensors are no longer reported, but
also the resume time increased.

To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

690eb7dec7 HID: logitech: Disable hi-res scrolling on USB
On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.

If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.

Disable hi-res scrolling on those devices until we implement scroll
events through HID++.

d7d94b2612 net: microchip: sparx5: fix PTP init/deinit not checking all ports
Check all ports instead of just port_count ports. PTP init was only
checking ports 0 to port_count. If the hardware ports are not mapped
starting from 0 then they would be missed, e.g. if only ports 20-30 were
mapped it would attempt to init ports 0-10, resulting in NULL pointers
when attempting to timestamp. Now it will init all mapped ports.

03702d4d29 uapi: add missing ip/ipv6 header dependencies for linux/stddef.h
Since commit 58e0be1ef6 ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:

$ make V=1 xskxceiver -C tools/testing/selftests/bpf
...
make: Entering directory '(...)/tools/testing/selftests/bpf'

c1d2ecdf5e neigh: make sure used and confirmed times are valid
Entries can linger in cache without timer for days, thanks to
the gc_thresh1 limit. As result, without traffic, the confirmed
time can be outdated and to appear to be in the future. Later,
on traffic, NUD_STALE entries can switch to NUD_DELAY and start
the timer which can see the invalid confirmed time and wrongly
switch to NUD_REACHABLE state instead of NUD_PROBE. As result,
timer is set many days in the future. This is more visible on
32-bit platforms, with higher HZ value.

Why this is a problem? While we expect unused entries to expire,
such entries stay in REACHABLE state for too long, locked in
cache. They are not expired normally, only when cache is full.

Problem and the wrong state change reported by Zhang Changzhong:

172.16.1.18 dev bond0 lladdr 0a:0e:0f:01:12:01 ref 1 used 350521/15994171/350520 probes 4 REACHABLE

350520 seconds have elapsed since this entry was last updated, but it is
still in the REACHABLE state (base_reachable_time_ms is 30000),
preventing lladdr from being updated through probe.

Fix it by ensuring timer is started with valid used/confirmed
times. Considering the valid time range is LONG_MAX jiffies,
we try not to go too much in the past while we are in
DELAY/PROBE state. There are also places that need
used/updated times to be validated while timer is not running.

51be2fffd6 cpufreq: qcom-hw: Fix cpufreq_driver->get() for non-LMH systems
On a sc7180-based Chromebook, when I go to
/sys/devices/system/cpu/cpu0/cpufreq I can see:

  cpuinfo_cur_freq:2995200
  cpuinfo_max_freq:1804800

  scaling_cur_freq:1804800
  scaling_max_freq:1804800

As you can see the `cpuinfo_cur_freq` is bogus. It turns out that this
bogus info started showing up as of commit c72cf0cb1d ("cpufreq:
qcom-hw: Fix the frequency returned by cpufreq_driver->get()"). That
commit seems to assume that everyone is on the LMH bandwagon, but
sc7180 isn't.

Let's go back to the old code in the case where LMH isn't used.
