commit 67c632b4a7 upstream.
Most drivers only populate the fields cycles and cs_id of system_counterval
in their get_time_fn() callback for get_device_system_crosststamp(), unless
they explicitly provide nanosecond values.
When the use_nsecs field was added to struct system_counterval, most
drivers did not care. Clock sources other than CSID_GENERIC could then get
converted in convert_base_to_cs() based on an uninitialized use_nsecs field,
which usually results in -EINVAL during the following range check.
Pass in a fully zero initialized system_counterval_t to cure that.

Commit e7607f7d6d ("ARM: 9443/1: Require linker to support KEEP within
OVERLAY for DCE") accidentally broke the binutils version restriction
that was added in commit 0d437918fb ("ARM: 9414/1: Fix build issue
with LD_DEAD_CODE_DATA_ELIMINATION"), reintroducing the segmentation
fault addressed by that workaround.
Restore the binutils version dependency by using
CONFIG_LD_CAN_USE_KEEP_IN_OVERLAY as an additional condition to ensure
that CONFIG_HAVE_LD_DEAD_CODE_DATA_ELIMINATION is only enabled with
binutils >= 2.36 and ld.lld >= 21.0.0.

After a recent change in clang to expose uninitialized warnings from const

advisor_mode_show().
mm/ksm.c:3687:11: error: variable 'output' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]

3690 | return sysfs_emit(buf, "%s\n", output);

Rewrite the if statement to implicitly make KSM_ADVISOR_NONE the else
branch so that it is obvious to the compiler that ksm_advisor can only be
KSM_ADVISOR_NONE or KSM_ADVISOR_SCAN_TIME due to the assignments in
advisor_mode_store().

commit 15f77764e9 upstream.
When application A submits jobs and application B submits a job with a
dependency on A's fence, the normal flow wakes up the scheduler after
processing each job. However, the optimization in
drm_sched_entity_add_dependency_cb() uses a callback that only clears
dependencies without waking up the scheduler.
When application A is killed before its jobs can run, the callback gets
triggered but only clears the dependency without waking up the scheduler,
causing the scheduler to enter sleep state and application B to hang.
Remove the optimization by deleting drm_sched_entity_clear_dep() and its
usage, ensuring the scheduler is always woken up when dependencies are
cleared.

The SMMU engine on HIP09 chip has a hardware issue.
SMMU pagetable prefetch features may prefetch and use a invalid PTE
even the PTE is valid at that time. This will cause the device trigger
fake pagefaults. The solution is to avoid prefetching by adding a
SYNC command when smmu mapping a iova. But the performance of nic has a
sharp drop. Then we do this workaround, always enable tx bounce buffer,
avoid mapping/unmapping on TX path.
This issue only affects HNS3, so we always enable
tx bounce buffer when smmu enabled to improve performance.

[ Upstream commit 897e8601b9 ]
The s390x ISM device data sheet clearly states that only one
request-response sequence is allowable per ISM function at any point in
time. Unfortunately as of today the s390/ism driver in Linux does not
honor that requirement. This patch aims to rectify that.
This problem was discovered based on Aliaksei's bug report which states
that for certain workloads the ISM functions end up entering error state
(with PEC 2 as seen from the logs) after a while and as a consequence
connections handled by the respective function break, and for future
connection requests the ISM device is not considered -- given it is in a
dysfunctional state. During further debugging PEC 3A was observed as
well.
A kernel message like
[ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61a
is a reliable indicator of the stated function entering error state
with PEC 2. Let me also point out that a kernel message like
[ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recovery
is a reliable indicator that the ISM function won't be auto-recovered
because the ISM driver currently lacks support for it.
On a technical level, without this synchronization, commands (inputs to
the FW) may be partially or fully overwritten (corrupted) by another CPU
trying to issue commands on the same function. There is hard evidence that
this can lead to DMB token values being used as DMB IOVAs, leading to
PEC 2 PCI events indicating invalid DMA. But this is only one of the
failure modes imaginable. In theory even completely losing one command
and executing another one twice and then trying to interpret the outputs
as if the command we intended to execute was actually executed and not
the other one is also possible. Frankly, I don't feel confident about
providing an exhaustive list of possible consequences.

There are 2 code path that call struct can_priv::do_set_mode:
- directly by a manual restart from the user space, via
can_changelink()
- delayed automatic restart after bus off (deactivated by default)
To prevent the NULL pointer deference, refuse a manual restart or
configure the automatic restart delay in can_changelink() and report
the error via extack to user space.
As an additional safety measure let can_restart() return an error if

[ Upstream commit 5a0df02999 ]
When the PF is processing an Admin Queue message to delete a VF's MACs
from the MAC filter, we currently check if the PF set the MAC and if
the VF is trusted.
This results in undesirable behaviour, where if a trusted VF with a
PF-set MAC sets itself down (which sends an AQ message to delete the
VF's MAC filters) then the VF MAC is erased from the interface.
This results in the VF losing its PF-set MAC which should not happen.
There is no need to check for trust at all, because an untrusted VF
cannot change its own MAC. The only check needed is whether the PF set
the MAC. If the PF set the MAC, then don't erase the MAC on link-down.
Resolve this by changing the deletion check only for PF-set MAC.
(the out-of-tree driver has also intentionally removed the check for VF
trust here with OOT driver version 2.26.8, this changes the Linux kernel
driver behaviour and comment to match the OOT driver behaviour)

[ Upstream commit 3ac9e29211 ]
The referenced commit replaced a call to __xfrm4|6_udp_encap_rcv() with
a custom check for non-ESP markers. But what the called function also
did was setting the transport header to the ESP header. The function
that follows, esp4|6_gro_receive(), relies on that being set when it calls
xfrm_parse_spi(). We have to set the full offset as the skb's head was
not moved yet so adding just the UDP header length won't work.

[ Upstream commit 7eb11c0ab7 ]
If we get preempted during xfrm_state_find, we could run
xfrm_state_look_at using a different pcpu_id than the one
xfrm_state_find saw. This could lead to ignoring states that should
have matched, and triggering acquires on a CPU that already has a pcpu
state.
xfrm_state_find starts on CPU1
pcpu_id = 1
lookup starts
<preemption, we're now on CPU2>
xfrm_state_look_at pcpu_id = 2
finds a state
found:
best->pcpu_num != pcpu_id (2 != 1)
if (!x && !error && !acquire_in_progress) {
...
xfrm_state_alloc
xfrm_init_tempstate
...
This can be avoided by passing the original pcpu_id down to all
xfrm_state_look_at() calls.
Also switch to raw_smp_processor_id, disabling preempting just to
re-enable it immediately doesn't really make sense.

In case of preemption, xfrm_state_look_at will find a different
pcpu_id and look up states for that other CPU. If we matched a state
for CPU2 in the state_cache while the lookup started on CPU1, we will
jump to "found", but the "best" state that we got will be ignored and
we will enter the "acquire" block. This block uses state_ptrs, which
isn't initialized at this point.
Let's initialize state_ptrs just after taking rcu_read_lock. This will
also prevent a possible misuse in the future, if someone adjusts this

[ Upstream commit 0d86a8d65c ]
The hv_fcopy_uio_daemon fails to correctly handle file copy requests
from Windows hosts (e.g. via Copy-VMFile) due to wchar_t size
differences between Windows and Linux. On Linux, wchar_t is 32 bit,
whereas Windows uses 16 bit wide characters.
Fix this by ensuring that file transfers from host to Linux guest
succeed with correctly decoded file names and paths.
- Treats file name and path as __u16 arrays, not wchar_t*.
- Allocates fixed-size buffers (W_MAX_PATH) for converted strings
instead of using malloc.
- Adds a check for target path length to prevent snprintf() buffer
overflow.

[ Upstream commit 45ebc7e6c1 ]
The virtqueue_resize() function was not correctly propagating error codes
from its internal resize helper functions, specifically
virtqueue_resize_packet() and virtqueue_resize_split(). If these helpers
returned an error, but the subsequent call to virtqueue_enable_after_reset()
succeeded, the original error from the resize operation would be masked.
Consequently, virtqueue_resize() could incorrectly report success to its
caller despite an underlying resize failure.
This change restores the original code behavior:
if (vdev->config->enable_vq_after_reset(_vq))
return -EBUSY;
return err;

[ Upstream commit 24b2f5df86 ]
The `tx_may_stop()` logic stops TX queues if free descriptors
(`sq->vq->num_free`) fall below the threshold of (`MAX_SKB_FRAGS` + 2).
If the total ring size (`ring_num`) is not strictly greater than this
value, queues can become persistently stopped or stop after minimal
use, severely degrading performance.
A single sk_buff transmission typically requires descriptors for:
- The virtio_net_hdr (1 descriptor)
- The sk_buff's linear data (head) (1 descriptor)
- Paged fragments (up to MAX_SKB_FRAGS descriptors)
This patch enforces that the TX ring size ('ring_num') must be strictly
greater than (MAX_SKB_FRAGS + 2). This ensures that the ring is
always large enough to hold at least one maximally-fragmented packet
plus at least one additional slot.
