Pull arm64 fixes from Will Deacon:
"Two important arm64 fixes ahead of the 6.16 release.
The first fixes a regression introduced during the merge window where
the KVM UUID (which is used to advertise KVM-specific hypercalls for
things like time synchronisation in the guest) was corrupted thanks to
an endianness bug introduced when converting the code to use the
UUID_INIT() helper.
The second fixes a stack-pointer corruption issue during
context-switch which has been observed in the wild when taking a
pseudo-NMI with shadow call stack enabled.
Summary:
- Fix broken UUID value for the KVM/arm64 hypervisor SMCCC interface
- Fix stack corruption on context-switch, primarily seen on (but not
limited to) configurations with both pNMI and SCS enabled"

"Including fixes from can and xfrm.
The TI regression notified last week is actually on our net-next tree,
it does not affect 6.16.

should not be critical, and I'm not sure that an additional week would
be enough to solve it.

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.

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.

The test is supposed to observe that the 'clash_resolve' stat counter
incremented (i.e., the code path was covered).
This check was incorrect, 'conntrack -S' needs to be called in the
revevant namespace, not the initial netns.
The clash resolution logic in conntrack is only exercised when multiple
packets with the same udp quadruple race. Depending on kernel config,
number of CPUs, scheduling policy etc. this might not trigger even
after several retries. Thus the script eventually returns SKIP if the
retry count is exceeded.
The udpclash tool with also exit with a failure if it did not observe
the expected number of replies.
In the script, make a note of this but do not fail anymore, just check if
the clash resolution logic triggered after all.
Remove the 'single-core' test: while unlikely, with preemptible kernel it
should be possible to also trigger clash resolution logic.
With this change the test will either SKIP or pass.
Hard error could be restored later once its clear whats going on, so
also dump 'conntrack -S' when some packets went missing to see if
conntrack dropped them on insert.

`cpu_switch_to()` and `call_on_irq_stack()` manipulate SP to change
to different stacks along with the Shadow Call Stack if it is enabled.
Those two stack changes cannot be done atomically and both functions
can be interrupted by SErrors or Debug Exceptions which, though unlikely,
is very much broken : if interrupted, we can end up with mismatched stacks
and Shadow Call Stack leading to clobbered stacks.
In `cpu_switch_to()`, it can happen when SP_EL0 points to the new task,
but x18 stills points to the old task's SCS. When the interrupt handler
tries to save the task's SCS pointer, it will save the old task
SCS pointer (x18) into the new task struct (pointed to by SP_EL0),
clobbering it.
In `call_on_irq_stack()`, it can happen when switching from the task stack
to the IRQ stack and when switching back. In both cases, we can be
interrupted when the SCS pointer points to the IRQ SCS, but SP points to
the task stack. The nested interrupt handler pushes its return addresses
on the IRQ SCS. It then detects that SP points to the task stack,
calls `call_on_irq_stack()` and clobbers the task SCS pointer with
the IRQ SCS pointer, which it will also use !
This leads to tasks returning to addresses on the wrong SCS,
or even on the IRQ SCS, triggering kernel panics via CONFIG_VMAP_STACK
or FPAC if enabled.
This is possible on a default config, but unlikely.
However, when enabling CONFIG_ARM64_PSEUDO_NMI, DAIF is unmasked and
instead the GIC is responsible for filtering what interrupts the CPU
should receive based on priority.
Given the goal of emulating NMIs, pseudo-NMIs can be received by the CPU
even in `cpu_switch_to()` and `call_on_irq_stack()`, possibly *very*
frequently depending on the system configuration and workload, leading
to unpredictable kernel panics.
Completely mask DAIF in `cpu_switch_to()` and restore it when returning.
Do the same in `call_on_irq_stack()`, but restore and mask around
the branch.
Mask DAIF even if CONFIG_SHADOW_CALL_STACK is not enabled for consistency
of behaviour between all configurations.
Introduce and use an assembly macro for saving and masking DAIF,
as the existing one saves but only masks IF.

nouveau_abi16_ioctl() function.
This turned out to be too strict, as userspace does use at least
write-only and write-read direction settings. Checking for both of these
still did not fix the issue, so the best we can do for the 6.16 release
is to revert back to what we've had since linux-3.16.
This version is still fragile, but at least it is known to work with
existing userspace. Fixing this properly requires a better understanding
of what commands are being passed from userspace in practice, and how
that relies on the undocumented (miss)behavior in nouveau_drm_ioctl().

can_priv::do_set_mode
Andrei Lalaev reported a NULL pointer deref when a CAN device is
restarted from Bus Off and the driver does not implement the struct
can_priv::do_set_mode callback.
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
can_priv::do_set_mode is not set instead of dereferencing it
unchecked.

qfq_delete_class
might_sleep could be trigger in the atomic context in qfq_delete_class.
qfq_destroy_class was moved into atomic context locked
by sch_tree_lock to avoid a race condition bug on
qfq_aggregate. However, might_sleep could be triggered by
qfq_destroy_class, which introduced sleeping in atomic context (path:
qfq_destroy_class->qdisc_put->__qdisc_destroy->lockdep_unregister_key
->might_sleep).
Considering the race is on the qfq_aggregate objects, keeping
qfq_rm_from_agg in the lock but moving the left part out can solve
this issue.

The mutexes qdev_mutex and chip->mutex are acquired in that order
throughout the driver. To preserve proper lock hierarchy and avoid
potential deadlocks, they must be released in the reverse
order of acquisition.
This change reorders the unlock sequence to first release chip->mutex
followed by qdev_mutex, ensuring consistency with the locking pattern.

gve_tx_timeout was calculating missed completions in a way that is only
relevant in the GQ queue format. Additionally, it was attempting to
disable device interrupts, which is not needed in either GQ or DQ queue
formats.
As a result, TX timeouts with the DQ queue format likely would have
triggered early resets without kicking the queue at all.
This patch drops the check for pending work altogether and always kicks
the queue after validating the queue has not seen a TX timeout too
recently.

On ASP versions v2.x we need to program the TX map vector register to
properly exercise end-to-end flow control, otherwise the TX engine can
either lock-up, or cause the hardware calculated checksum to be
wrong/corrupted when multiple back to back packets are being submitted
for transmission. This register defaults to 0, which means no flow

Matthieu Baerts says:
====================
selftests: mptcp: connect: cover alt modes
mptcp_connect.sh can be executed manually with "-m <MODE>" and "-C" to
make sure everything works as expected when using "mmap" and "sendfile"
modes instead of "poll", and with the MPTCP checksum support.
These modes should be validated, but they are not when the selftests are
executed via the kselftest helpers. It means that most CIs validating
these selftests, like NIPA for the net development trees and LKFT for
the stable ones, are not covering these modes.
To fix that, new test programs have been added, simply calling
mptcp_connect.sh with the right parameters.
The first patch can be backported up to v5.6, and the second one up to
v5.14.

The checksum mode has been added a while ago, but it is only validated
when manually launching mptcp_connect.sh with "-C".
The different CIs were then not validating these MPTCP Connect tests
with checksum enabled. To make sure they do, add a new test program
executing mptcp_connect.sh with the checksum mode.

The "mmap" and "sendfile" alternate modes for mptcp_connect.sh/.c are
available from the beginning, but only tested when mptcp_connect.sh is
manually launched with "-m mmap" or "-m sendfile", not via the
kselftests helpers.
The MPTCP CI was manually running "mptcp_connect.sh -m mmap", but not
"-m sendfile". Plus other CIs, especially the ones validating the stable
releases, were not validating these alternate modes.
To make sure these modes are validated by these CIs, add two new test
programs executing mptcp_connect.sh with the alternate modes.

Unfortunately some systems have left the factory with an uninitialized
value of 0xFFFF at register address 0x3F (checksum word location).
So on Tiger Lake platform we ignore the computed checksum when such

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)

Currently the tx_dropped field in VF stats is not updated correctly
when reading stats from the PF. This is because it reads from
i40e_eth_stats.tx_discards which seems to be unused for per VSI stats,
as it is not updated by i40e_update_eth_stats() and the corresponding
register, GLV_TDPC, is not implemented[1].
Use i40e_eth_stats.tx_errors instead, which is actually updated by
i40e_update_eth_stats() by reading from GLV_TEPC.
To test, create a VF and try to send bad packets through it:

Commit 13423063c7cb ("arm64: kvm, smccc: Introduce and use API for
getting hypervisor UUID") replaced the explicit register constants
with the UUID_INIT macro. However, there is an endian issue, meaning
the UUID generated and used in the handshake didn't match UUID prior to
the commit.
The change in UUID causes the SMCCC vendor handshake to fail with older
guest kernels, meaning devices such as PTP were not available in the
guest.
This patch updates the parameters to the macro to generate a UUID which
matches the previous value, and re-establish backwards compatibility
with older guest kernels.

Update the MAINTAINERS file to reflect the following changes for two Intel
platform drivers:
- Tony has agreed to take over maintainership of the Intel In-Field Scan
(IFS) driver, and is now listed as the new maintainer.
- Remove myself as the maintainer for the Slim BootLoader (SBL) firmware
update driver and mark it as Orphan. To the best of my knowledge, there
is no one familiar with SBL who can take over this role.
These changes are being made as I will soon be leaving Intel.

The mute LED on the HP Pavilion Laptop 15-eg0xxx,
which uses the ALC287 codec, didn't work.
This patch fixes the issue by enabling the ALC287_FIXUP_HP_GPIO_LED quirk.
Tested on a physical device, the LED now works as intended.
