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.

devlink: Fix netdev notifier chain corruption
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

igb: conditionalize I2C bit banging on external thermal sensor support
Commit
a97f8783a937 ("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
a97f8783a937
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
a97f8783a937 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.

apparmor: Fix regression in compat permissions for getattr
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.

gpiolib: acpi: Add a ignore wakeup quirk for Clevo NH5xAx
The commit
1796f808e4bb ("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.

sched/psi: Fix use-after-free in ep_remove_wait_queue()
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
42288cb44c4b ("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.

net: mpls: fix stale pointer if allocation fails during device rename
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.

drm/vmwgfx: Do not drop the reference to the handle too soon
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.

"Certain AMD processors are vulnerable to a cross-thread return address
predictions bug. When running in SMT mode and one of the sibling
threads transitions out of C0 state, the other thread gets access to
twice as many entries in the RSB, but unfortunately the predictions of
the now-halted logical processor are not purged. Therefore, the
executing processor could speculatively execute from locations that
the now-halted processor had trained the RSB on.
The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB
when context switching to the idle thread. However, KVM allows a VMM
to prevent exiting guest mode when transitioning out of C0 using the
KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change
this behavior. To mitigate the cross-thread return address predictions
bug, a VMM must not be allowed to override the default behavior to
intercept C0 transitions.
These patches introduce a KVM module parameter that, if set, will
prevent the user from disabling the HLT, MWAIT and CSTATE exits"

The order as indicated by the publicly available reference manual of the i.MX8MP [1]

* initiate the programming sequence
* set the values for PPS period and start time
* start the pulse train generation.
This is currently not used in dwmac5_flex_pps_config(), which instead does:
* initiate the programming sequence and immediately start the pulse train generation

This caused the period values written not to take effect until the FlexPPS output was

ice: fix lost multicast packets in promisc mode
There was a problem reported to us where the addition of a VF with an IPv6
address ending with a particular sequence would cause the parent device on
the PF to no longer be able to respond to neighbor discovery packets.
In this case, we had an ovs-bridge device living on top of a VLAN, which
was on top of a PF, and it would not be able to talk anymore (the neighbor
entry would expire and couldn't be restored).
The root cause of the issue is that if the PF is asked to be in IFF_PROMISC
mode (promiscuous mode) and it had an ipv6 address that needed the
33:33:ff:00:00:04 multicast address to work, then when the VF was added
with the need for the same multicast address, the VF would steal all the
traffic destined for that address.
The ice driver didn't auto-subscribe a request of IFF_PROMISC to the
"multicast replication from other port's traffic" meaning that it won't get
for instance, packets with an exact destination in the VF, as above.
The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04,
results in no packets for that multicast address making it to the PF (which
is in promisc but NOT "multicast replication").
The fix is to enable "multicast promiscuous" whenever the driver is asked
to enable IFF_PROMISC, and make sure to disable it when appropriate.

drm: Disable dynamic debug as broken
CONFIG_DRM_USE_DYNAMIC_DEBUG breaks debug prints for (at least modular)

damage is done and all debugs from driver probe are lost. This makes

"Fix showing of TASK_COMM_LEN instead of its value
The TASK_COMM_LEN was converted from a macro into an enum so that BTF
would have access to it. But this unfortunately caused TASK_COMM_LEN
to display in the format fields of trace events, as they are created
by the TRACE_EVENT() macro and such, macros convert to their values,
where as enums do not.
To handle this, instead of using the field itself to be display, save
the value of the array size as another field in the trace_event_fields
structure, and use that instead.
Not only does this fix the issue, but also converts the other trace
events that have this same problem (but were not breaking tooling).

Sometimes, it would also show up as corruption in the free list pointer
and cause crashes.
After bisecting the issue, we found the issue started from commit
e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"):
if (put_page_testzero(page))
free_the_page(page, order);
else if (!PageHead(page))
while (order-- > 0)
free_the_page(page + (1 << order), order);
So the problem is the check PageHead is racy because at this point we
already dropped our reference to the page. So even if we came in with
compound page, the page can already be freed and PageHead can return
false and we will end up freeing all the tail pages causing double free.

tracing: Fix TASK_COMM_LEN in trace event format file
After commit
3087c61ed2c4 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN"),
the content of the format file under
/sys/kernel/tracing/events/task/task_newtask was changed from
field:char comm[16]; offset:12; size:16; signed:0;
to
field:char comm[TASK_COMM_LEN]; offset:12; size:16; signed:0;
John reported that this change breaks older versions of perfetto.
Then Mathieu pointed out that this behavioral change was caused by the
use of __stringify(_len), which happens to work on macros, but not on enum
labels. And he also gave the suggestion on how to fix it:
:One possible solution to make this more robust would be to extend
:struct trace_event_fields with one more field that indicates the length
:of an array as an actual integer, without storing it in its stringified
:form in the type, and do the formatting in f_show where it belongs.
The result as follows after this change,
$ cat /sys/kernel/tracing/events/task/task_newtask/format
field:char comm[16]; offset:12; size:16; signed:0;

nfsd: don't destroy global nfs4_file table in per-net shutdown
The nfs4_file table is global, so shutting it down when a containerized

ALSA: hda: Fix codec device field initializan
Commit
f2bd1c5ae2cb ("ALSA: hda: Fix page fault in
snd_hda_codec_shutdown()") relocated initialization of several codec
device fields. Due to differences between codec_exec_verb() and
snd_hdac_bus_exec_bus() in how they handle VERB execution - the latter
does not touch PM - assigning ->exec_verb to codec_exec_verb() causes PM
to be engaged before it is configured for the device. Configuration of
PM for the ASoC HDAudio sound card is done with snd_hda_set_power_save()
during skl_hda_audio_probe() whereas the assignment happens early, in
snd_hda_codec_device_init().
Revert to previous behavior to avoid problems caused by too early PM
manipulation.
