8192688826 ALSA: hda/tas2781: Skip UEFI calibration on ASUS ROG Xbox Ally X
commit b7e26c8bda upstream.

There is currently an issue with UEFI calibration data parsing for some
TAS devices, like the ASUS ROG Xbox Ally X (RC73XA), that causes audio
quality issues such as gaps in playback. Until the issue is root caused
and fixed, add a quirk to skip using the UEFI calibration data and fall
back to using the calibration data provided by the DSP firmware, which
restores full speaker functionality on affected devices.

580581bd4a selftests: kvm: replace numbered sync points with actions
commit a1025dcd37 upstream.

Rework the guest=>host syncs in the AMX test to use named actions instead
of arbitrary, incrementing numbers.  The "stage" of the test has no real
meaning, what matters is what action the test wants the host to perform.
The incrementing numbers are somewhat helpful for triaging failures, but
fully debugging failures almost always requires a much deeper dive into
the test (and KVM).

Using named actions not only makes it easier to extend the test without
having to shift all sync point numbers, it makes the code easier to read.

2674004ddc scsi: core: Fix error handler encryption support
commit 9a49157dee upstream.

Some low-level drivers (LLD) access block layer crypto fields, such as
rq->crypt_keyslot and rq->crypt_ctx within `struct request`, to
configure hardware for inline encryption.  However, SCSI Error Handling
(EH) commands (e.g., TEST UNIT READY, START STOP UNIT) should not
involve any encryption setup.

To prevent drivers from erroneously applying crypto settings during EH,
this patch saves the original values of rq->crypt_keyslot and
rq->crypt_ctx before an EH command is prepared via scsi_eh_prep_cmnd().
These fields in the 'struct request' are then set to NULL.  The original
values are restored in scsi_eh_restore_cmnd() after the EH command
completes.

This ensures that the block layer crypto context does not leak into EH
command execution.

3667af036e selftests/bpf: Fix selftest verif_scale_strobemeta failure with llvm22
commit 4f8543b5f2 upstream.

With latest llvm22, I hit the verif_scale_strobemeta selftest failure
below:
  $ ./test_progs -n 618
  libbpf: prog 'on_event': BPF program load failed: -E2BIG
  libbpf: prog 'on_event': -- BEGIN PROG LOAD LOG --
  BPF program is too large. Processed 1000001 insn

  libbpf: failed to load object 'strobemeta.bpf.o'
  scale_test:FAIL:expect_success unexpected error: -7 (errno 7)
  #618     verif_scale_strobemeta:FAIL

But if I increase the verificaiton insn limit from 1M to 10M, the above
test_progs run actually will succeed. The below is the result from veristat:
  $ ./veristat strobemeta.bpf.o
  Processing 'strobemeta.bpf.o'...

  ----------------  --------  -------  -------------  -------  ------  ------------  ----------
  Done. Processed 1 files, 0 programs. Skipped 1 files, 0 programs.

Further debugging shows the llvm commit [1] is responsible for the verificaiton
failure as it tries to convert certain switch statement to if-condition. Such
change may cause different transformation compared to original switch statement.

In bpf program strobemeta.c case, the initial llvm ir for read_int_var() function is
  define internal void @read_int_var(ptr noundef %0, i64 noundef %1, ptr noundef %2,
      ptr noundef %3, ptr noundef %4) #2 !dbg !535 {
    %6 = alloca ptr, align 8
    %7 = alloca i64, align 8
    %8 = alloca ptr, align 8
    %9 = alloca ptr, align 8
    %10 = alloca ptr, align 8
    %11 = alloca ptr, align 8
    %12 = alloca i32, align 4
    ...
    %20 = icmp ne ptr %19, null, !dbg !561
    br i1 %20, label %22, label %21, !dbg !562

  21:                                               ; preds = %5
    store i32 1, ptr %12, align 4
    br label %48, !dbg !563

  22:
    %23 = load ptr, ptr %9, align 8, !dbg !564
    ...

  47:                                               ; preds = %38, %22
    store i32 0, ptr %12, align 4, !dbg !588

  48:                                               ; preds = %47, %21
    call void @llvm.lifetime.end.p0(ptr %11) #4, !dbg !588
    %49 = load i32, ptr %12, align 4
    switch i32 %49, label %51 [
      i32 0, label %50
      i32 1, label %50
    ]

  50:                                               ; preds = %48, %48
    ret void, !dbg !589

  51:                                               ; preds = %48
    unreachable
  }

Note that the above 'switch' statement is added by clang frontend.
Without [1], the switch statement will survive until SelectionDag,
so the switch statement acts like a 'barrier' and prevents some
transformation involved with both 'before' and 'after' the switch statement.

But with [1], the switch statement will be removed during middle end
optimization and later middle end passes (esp. after inlining) have more
freedom to reorder the code.

The following is the related source code:

  static void *calc_location(struct strobe_value_loc *loc, void *tls_base):
        bpf_probe_read_user(&tls_ptr, sizeof(void *), dtv);
        /* if pointer has (void *)-1 value, then TLS wasn't initialized yet */
        return tls_ptr && tls_ptr != (void *)-1
                ? tls_ptr + tls_index.offset
                : NULL;

  In read_int_var() func, we have:
        void *location = calc_location(&cfg->int_locs[idx], tls_base);
        if (!location)
                return;

        bpf_probe_read_user(value, sizeof(struct strobe_value_generic), location);
        ...

The static func calc_location() is called inside read_int_var(). The asm code
without [1]:
     77: .123....89 (85) call bpf_probe_read_user#112
     78: ........89 (79) r1 = *(u64 *)(r10 -368)
     79: .1......89 (79) r2 = *(u64 *)(r10 -8)
     80: .12.....89 (bf) r3 = r2
     81: .123....89 (0f) r3 += r1
     82: ..23....89 (07) r2 += 1
     83: ..23....89 (79) r4 = *(u64 *)(r10 -464)
     84: ..234...89 (a5) if r2 < 0x2 goto pc+13
     85: ...34...89 (15) if r3 == 0x0 goto pc+12
     86: ...3....89 (bf) r1 = r10
     87: .1.3....89 (07) r1 += -400
     88: .1.3....89 (b4) w2 = 16
In this case, 'r2 < 0x2' and 'r3 == 0x0' go to null 'locaiton' place,
so the verifier actually prefers to do verification first at 'r1 = r10' etc.

The asm code with [1]:
    119: .123....89 (85) call bpf_probe_read_user#112
    120: ........89 (79) r1 = *(u64 *)(r10 -368)
    121: .1......89 (79) r2 = *(u64 *)(r10 -8)
    122: .12.....89 (bf) r3 = r2
    123: .123....89 (0f) r3 += r1
    124: ..23....89 (07) r2 += -1
    125: ..23....89 (a5) if r2 < 0xfffffffe goto pc+6
    126: ........89 (05) goto pc+17
    ...
    144: ........89 (b4) w1 = 0
    145: .1......89 (6b) *(u16 *)(r8 +80) = r1
In this case, if 'r2 < 0xfffffffe' is true, the control will go to
non-null 'location' branch, so 'goto pc+17' will actually go to
null 'location' branch. This seems causing tremendous amount of
verificaiton state.

To fix the issue, rewrite the following code
  return tls_ptr && tls_ptr != (void *)-1
                ? tls_ptr + tls_index.offset
                : NULL;
to if/then statement and hopefully these explicit if/then statements
are sticky during middle-end optimizations.

Test with llvm20 and llvm21 as well and all strobemeta related selftests
are passed.

While FIFO/RR have static priority, DEADLINE is a dynamic priority
scheme. Notably it has static priority -1. Do not assume the priority
doesn't change for deadline tasks just because the static priority
doesn't change.

This ensures DL always sees {DE,EN}QUEUE_MOVE where appropriate.

cf40c73ab2 i2c: imx-lpi2c: change to PIO mode in system-wide suspend/resume progress
[ Upstream commit f2a3f51365 ]

EDMA resumes early and suspends late in the system power transition
sequence, while LPI2C enters the NOIRQ stage for both suspend and resume.
This means LPI2C resources become available before EDMA is fully resumed.
Once IRQs are enabled, a slave device may immediately trigger an LPI2C
transfer. If the transfer length meets DMA requirements, the driver will
attempt to use EDMA even though EDMA may still be unavailable.

This timing gap can lead to transfer failures. To prevent this, force
LPI2C to use PIO mode during system-wide suspend and resume transitions.
This reduces dependency on EDMA and avoids using an unready DMA resource.

612cbe1aeb soundwire: bus: fix off-by-one when allocating slave IDs

ida_alloc_max() interprets its max argument as inclusive.

Using SDW_FW_MAX_DEVICES(16) therefore allows an ID of 16 to be
allocated, but the IRQ domain created for the bus is sized for IDs
0-15.  If 16 is returned, irq_create_mapping() fails and the driver
ends up with an invalid IRQ mapping.

Limit the allocation to 0-15 by passing SDW_FW_MAX_DEVICES - 1.

c589bc6433 selftests/landlock: Fix TCP bind(AF_UNSPEC) test case
[ Upstream commit bd09d9a05c ]

The nominal error code for bind(AF_UNSPEC) on an IPv6 socket
is -EAFNOSUPPORT, not -EINVAL. -EINVAL is only returned when
the supplied address struct is too short, which happens to be
the case in current selftests because they treat AF_UNSPEC
like IPv4 sockets do: as an alias for AF_INET (which is a
16-byte struct instead of the 24 bytes required by IPv6
sockets).

Make the union large enough for any address (by adding struct
sockaddr_storage to the union), and make AF_UNSPEC addresses
large enough for any family.

Test for -EAFNOSUPPORT instead, and add a dedicated test case
for truncated inputs with -EINVAL.

75ef8c94d4 landlock: Fix TCP handling of short AF_UNSPEC addresses
[ Upstream commit e4d82cbce2 ]

current_check_access_socket() treats AF_UNSPEC addresses as
AF_INET ones, and only later adds special case handling to
allow connect(AF_UNSPEC), and on IPv4 sockets
bind(AF_UNSPEC+INADDR_ANY).
This would be fine except AF_UNSPEC addresses can be as
short as a bare AF_UNSPEC sa_family_t field, and nothing
more. The AF_INET code path incorrectly enforces a length of
sizeof(struct sockaddr_in) instead.

Move AF_UNSPEC edge case handling up inside the switch-case,
before the address is (potentially incorrectly) treated as
AF_INET.

The "index" variable is used as an index into the usbphyc->phys[] array
which has usbphyc->nphys elements.  So if it is equal to usbphyc->nphys
then it is one element out of bounds.  The "index" comes from the

4ac15caa27 phy: qcom-qusb2: Fix NULL pointer dereference on early suspend
[ Upstream commit 1ca52c0983 ]

Enabling runtime PM before attaching the QPHY instance as driver data
can lead to a NULL pointer dereference in runtime PM callbacks that
expect valid driver data. There is a small window where the suspend
callback may run after PM runtime enabling and before runtime forbid.
This causes a sporadic crash during boot:

```
Unable to handle kernel NULL pointer dereference at virtual address 00000000000000a1

lr : pm_generic_runtime_suspend+0x2c/0x44
[...]
```

Attach the QPHY instance as driver data before enabling runtime PM to
prevent NULL pointer dereference in runtime PM callbacks.

Reorder pm_runtime_enable() and pm_runtime_forbid() to prevent a
short window where an unnecessary runtime suspend can occur.

Use the devres-managed version to ensure PM runtime is symmetrically
disabled during driver removal for proper cleanup.

be655c3736 dmaengine: tegra-adma: Fix use-after-free
[ Upstream commit 2efd07a7c3 ]

A use-after-free bug exists in the Tegra ADMA driver when audio streams
are terminated, particularly during XRUN conditions. The issue occurs
when the DMA buffer is freed by tegra_adma_terminate_all() before the
vchan completion tasklet finishes accessing it.

The race condition follows this sequence:

  1. DMA transfer completes, triggering an interrupt that schedules the
     completion tasklet (tasklet has not executed yet)
  2. Audio playback stops, calling tegra_adma_terminate_all() which
     frees the DMA buffer memory via kfree()
  3. The scheduled tasklet finally executes, calling vchan_complete()
     which attempts to access the already-freed memory

Since tasklets can execute at any time after being scheduled, there is
no guarantee that the buffer will remain valid when vchan_complete()
runs.

Fix this by properly synchronizing the virtual channel completion:
 - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the
   descriptors as terminated instead of freeing the descriptor.
 - Add the callback tegra_adma_synchronize() that calls
   vchan_synchronize() which kills any pending tasklets and frees any
   terminated descriptors.

974f241095 dmaengine: mmp_pdma: fix DMA mask handling
[ Upstream commit 49400b701e ]

The driver's existing logic for setting the DMA mask for "marvell,pdma-1.0"
was flawed. It incorrectly relied on pdev->dev->coherent_dma_mask instead
of declaring the hardware's fixed addressing capability. A cleaner and
more correct approach is to define the mask directly based on the hardware
limitations.

The MMP/PXA PDMA controller is a 32-bit DMA engine. This is supported by
datasheets and various dtsi files for PXA25x, PXA27x, PXA3xx, and MMP2,
all of which are 32-bit systems.

This patch simplifies the driver's logic by replacing the 'u64 dma_mask'
field with a simpler 'u32 dma_width' to store the addressing capability
in bits. The complex if/else block in probe() is then replaced with a
single, clear call to dma_set_mask_and_coherent(). This sets a fixed
32-bit DMA mask for "marvell,pdma-1.0" and a 64-bit mask for
"spacemit,k1-pdma," matching each device's hardware capabilities.

Finally, this change also works around a specific build error encountered
with clang-20 on x86_64 allyesconfig. The shift-count-overflow error is
caused by a known clang compiler issue where the DMA_BIT_MASK(n) macro's
ternary operator is not correctly evaluated in static initializers. By
moving the macro's evaluation into the probe() function, the driver avoids
this compiler bug.

e1a30e1ab3 drm/amdgpu/userq: Fix fence reference leak on queue teardown v2
[ Upstream commit b2426a211d ]

The user mode queue keeps a pointer to the most recent fence in
userq->last_fence. This pointer holds an extra dma_fence reference.

When the queue is destroyed, we free the fence driver and its xarray,
but we forgot to drop the last_fence reference.

Because of the missing dma_fence_put(), the last fence object can stay
alive when the driver unloads. This leaves an allocated object in the
amdgpu_userq_fence slab cache and triggers

This is visible during driver unload as:

  BUG amdgpu_userq_fence: Objects remaining on __kmem_cache_shutdown()
  kmem_cache_destroy amdgpu_userq_fence: Slab cache still has objects
  Call Trace:
    kmem_cache_destroy
    amdgpu_userq_fence_slab_fini
    amdgpu_exit
    __do_sys_delete_module

Fix this by putting userq->last_fence and clearing the pointer during
amdgpu_userq_fence_driver_free().

This makes sure the fence reference is released and the slab cache is
empty when the module exits.

[Why]
The PSR message was moved in commit 4321742c39 ("drm/amd/display:

for every single link without showing which link is which.  This can
send a confusing message to the user.

The word length is the physical width of the channel slots. So the
hw_params would misconfigure when format width and physical width
doesn't match. Like S24_LE which has data width of 24 bits but physical
width of 32 bits. So if using asymmetric formats you will get a lot of
noise.

07d6d21b85 ASoC: sdw_utils: cs42l43: Enable Headphone pin for LINEOUT jack type
[ Upstream commit 390caeed08 ]

The CS42L43 codec's load detection can return different impedance values
that map to either HEADPHONE or LINEOUT jack types. However, the
soc_jack_pins array only maps SND_JACK_HEADPHONE to the "Headphone" DAPM
pin, not SND_JACK_LINEOUT.

When headphones are detected with an impedance that maps to LINEOUT
(such as impedance value 0x2), the driver reports SND_JACK_LINEOUT.
Since this doesn't match the jack pin mask, the "Headphone" DAPM pin
is not activated, and no audio is routed to the headphone outputs.

Fix by adding SND_JACK_LINEOUT to the Headphone pin mask, so that both
headphone and line-out detection properly enable the headphone output
path.

This fixes no audio output on devices like the Lenovo ThinkPad P16 Gen 3
where headphones are detected with LINEOUT impedance.

722de94521 dst: fix races in rt6_uncached_list_del() and rt_del_uncached_list()
[ Upstream commit 9a6f0c4d57 ]

syzbot was able to crash the kernel in rt6_uncached_list_flush_dev()
in an interesting way [1]

Crash happens in list_del_init()/INIT_LIST_HEAD() while writing
list->prev, while the prior write on list->next went well.

static inline void INIT_LIST_HEAD(struct list_head *list)
{
	WRITE_ONCE(list->next, list); // This went well
	WRITE_ONCE(list->prev, list); // Crash, @list has been freed.
}

Issue here is that rt6_uncached_list_del() did not attempt to lock
ul->lock, as list_empty(&rt->dst.rt_uncached) returned
true because the WRITE_ONCE(list->next, list) happened on the other CPU.

We might use list_del_init_careful() and list_empty_careful(),
or make sure rt6_uncached_list_del() always grabs the spinlock
whenever rt->dst.rt_uncached_list has been set.

A similar fix is neeed for IPv4.

11dd9a9ef4 net: hv_netvsc: reject RSS hash key programming without RX indirection table
[ Upstream commit d235649558 ]

RSS configuration requires a valid RX indirection table. When the device
reports a single receive queue, rndis_filter_device_add() does not
allocate an indirection table, accepting RSS hash key updates in this
state leads to a hang.

Fix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return
-EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device
capabilities and prevents incorrect behavior.

78ee2958b0 ALSA: hda/cirrus_scodec_test: Fix test suite name
[ Upstream commit 6a0243c402 ]

Change the test suite name string to "snd-hda-cirrus-scodec-test".

It was incorrectly named "snd-hda-scodec-cs35l56-test", a leftover
from when the code under test was actually in the cs35l56 driver.

aaa969ffe3 ALSA: hda/cirrus_scodec_test: Fix incorrect setup of gpiochip
[ Upstream commit c5e96e54ec ]

Set gpiochip parent to the struct device of the dummy GPIO driver
so that the software node will be associated with the GPIO chip.

The recent commit e5d527be7e ("gpio: swnode: don't use the
swnode's name as the key for GPIO lookup") broke cirrus_scodec_test,
because the software node no longer gets associated with the GPIO
driver by name.

Instead, setting struct gpio_chip.parent to the owning struct device
will find the node using a normal fwnode lookup.
