drm/xe/queue: Call fini on exec queue creation fail
Every call to queue init should have a corresponding fini call.
Skipping this would mean skipping removal of the queue from GuC list
(which is part of guc_id allocation). A damaged queue stored in
exec_queue_lookup list would lead to invalid memory reference,
sooner or later.

Call fini to free guc_id. This must be done before any internal
LRCs are freed.

Since the finalization with this extra call became very similar to
__xe_exec_queue_fini(), reuse that. To make this reuse possible,
alter xe_lrc_put() so it can survive NULL parameters, like other
similar functions.

v2: Reuse _xe_exec_queue_fini(). Make xe_lrc_put() aware of NULLs.

drm/xe: Do not preempt fence signaling CS instructions
If a batch buffer is complete, it makes little sense to preempt the
fence signaling instructions in the ring, as the largest portion of the
work (the batch buffer) is already done and fence signaling consists of
only a few instructions. If these instructions are preempted, the GuC
would need to perform a context switch just to signal the fence, which
is costly and delays fence signaling. Avoid this scenario by disabling
preemption immediately after the BB start instruction and re-enabling it
after executing the fence signaling instructions.

2e3649e237 drm/syncobj: Fix handle <-> fd ioctls with dirty stack
Consider the following application:

    #include <fcntl.h>
    #include <string.h>
    #include <drm/drm.h>
    #include <sys/ioctl.h>

    int main(void) {
        int fd = open("/dev/dri/renderD128", O_RDWR);
        struct drm_syncobj_create arg1;
        ioctl(fd, DRM_IOCTL_SYNCOBJ_CREATE, &arg1);
        struct drm_syncobj_handle arg2;
        memset(&arg2, 1, sizeof(arg2)); // simulate dirty stack
        arg2.handle = arg1.handle;
        arg2.flags = 0;
        arg2.fd = 0;
        arg2.pad = 0;
        // arg2.point = 0; // userspace is required to set point to 0
        ioctl(fd, DRM_IOCTL_SYNCOBJ_HANDLE_TO_FD, &arg2);
    }

The last ioctl returns EINVAL because args->point is not 0. However,
userspace developed against older kernel versions is not aware of the
new point field and might therefore not initialize it.

The correct check would be

    if (args->flags & DRM_SYNCOBJ_FD_TO_HANDLE_FLAGS_TIMELINE)
        return -EINVAL;

However, there might already be userspace that relies on this not
returning an error as long as point == 0. Therefore use the more lenient
check.

The datasheet specifies, that the IRQ_B pin is pulled low when any

the application processor reads the INT1 register. As it specifies a

Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt
and instead rely on the flag from the device tree.

2df6162785 can: gs_usb: gs_can_open(): always configure bitrates before starting device
So far the driver populated the struct can_priv::do_set_bittiming() and
struct can_priv::fd::do_set_data_bittiming() callbacks.

Before bringing up the interface, user space has to configure the bitrates.
With these callbacks the configuration is directly forwarded into the CAN
hardware. Then the interface can be brought up.

An ifdown-ifup cycle (without changing the bit rates) doesn't re-configure
the bitrates in the CAN hardware. This leads to a problem with the
CANable-2.5 [1] firmware, which resets the configured bit rates during
ifdown.

To fix the problem remove both bit timing callbacks and always configure
the bitrates in the struct net_device_ops::ndo_open() callback.

9073428bb2 x86/sev: Allow IBPB-on-Entry feature for SNP guests
The SEV-SNP IBPB-on-Entry feature does not require a guest-side
implementation. It was added in Zen5 h/w, after the first SNP Zen
implementation, and thus was not accounted for when the initial set of SNP
features were added to the kernel.

In its abundant precaution, commit

  8c29f01654 ("x86/sev: Add SEV-SNP guest feature negotiation support")

included SEV_STATUS' IBPB-on-Entry bit as a reserved bit, thereby masking
guests from using the feature.

Allow guests to make use of IBPB-on-Entry when supported by the hypervisor, as
the bit is now architecturally defined and safe to expose.

4ca191cec1 x86/boot/sev: Move SEV decompressor variables into the .data section
As part of the work to remove the dependency on calling into the decompressor
code (startup_64()) for a UEFI boot, a call to rmpadjust() was removed from
sev_enable() in favor of checking the value of the snp_vmpl variable.

When booting through a non-UEFI path and calling startup_64(), the call to
sev_enable() is performed before the BSS section is zeroed. With the removal
of the rmpadjust() call and the corresponding check of the return code, the
snp_vmpl variable is checked.

Since the kernel is running at VMPL0, the snp_vmpl variable will not have been
set and should be the default value of 0.  However, since the call occurs
before the BSS is zeroed, the snp_vmpl variable may not actually be zero,
which will cause the guest boot to fail.

Since the decompressor relocates itself, the BSS would need to be cleared both
before and after the relocation, but this would, in effect, cause all of the
changes to BSS variables before relocation to be lost after relocation.

Instead, move the snp_vmpl variable into the .data section so that it is
initialized and the value made safe during relocation. As a pre-caution
against future changes, move other SEV-related decompressor variables into the
.data section, too.

968b098220 can: esd_usb: add endpoint type validation
esd_usb_probe() constructs bulk pipes for two endpoints without
verifying their transfer types:

  - usb_rcvbulkpipe(dev->udev, 1) for RX (version reply, async RX data)
  - usb_sndbulkpipe(dev->udev, 2) for TX (version query, CAN frames)

A malformed USB device can present these endpoints with transfer types
that differ from what the driver assumes, triggering the WARNING in
usb_submit_urb().

Use usb_find_common_endpoints() to discover and validate the first
bulk IN and bulk OUT endpoints at probe time, before any allocation.
Found pipes are saved to struct esd_usb and code uses them directly
instead of making pipes in place.

Similar to
- commit 136bed0bfd ("can: mcba_usb: properly check endpoint type")
  which established the usb_find_common_endpoints() + stored pipes
  pattern for CAN USB drivers.

c35636e91e can: bcm: fix locking for bcm_op runtime updates
Commit c2aba69d0c ("can: bcm: add locking for bcm_op runtime updates")
added a locking for some variables that can be modified at runtime when
updating the sending bcm_op with a new TX_SETUP command in bcm_tx_setup().

Usually the RX_SETUP only handles and filters incoming traffic with one
exception: When the RX_RTR_FRAME flag is set a predefined CAN frame is
sent when a specific RTR frame is received. Therefore the rx bcm_op uses
bcm_can_tx() which uses the bcm_tx_lock that was only initialized in
bcm_tx_setup(). Add the missing spin_lock_init() when allocating the
bcm_op in bcm_rx_setup() to handle the RTR case properly.

48647d3f9a slab: distinguish lock and trylock for sheaf_flush_main()
sheaf_flush_main() can be called from __pcs_replace_full_main() where
it's fine if the trylock fails, and pcs_flush_all() where it's not
expected to and for some flush callers (when destroying the cache or
memory hotremove) it would be actually a problem if it failed and left
the main sheaf not flushed. The flush callers can however safely use
local_lock() instead of trylock.

The trylock failure should not happen in practice on !PREEMPT_RT, but
can happen on PREEMPT_RT. The impact is limited in practice because when
a trylock fails in the kmem_cache_destroy() path, it means someone is
using the cache while destroying it, which is a bug on its own. The memory
hotremove path is unlikely to be employed in a production RT config, but
it's possible.

To fix this, split the function into sheaf_flush_main() (using
local_lock()) and sheaf_try_flush_main() (using local_trylock()) where
both call __sheaf_flush_main_batch() to flush a single batch of objects.
This will also allow lockdep to verify our context assumptions.

The problem was raised in an off-list question by Marcelo.

0d10393d5e xfrm: iptfs: validate inner IPv4 header length in IPTFS payload
Add validation of the inner IPv4 packet tot_len and ihl fields parsed
from decrypted IPTFS payloads in __input_process_payload(). A crafted
ESP packet containing an inner IPv4 header with tot_len=0 causes an
infinite loop: iplen=0 leads to capturelen=min(0, remaining)=0, so the
data offset never advances and the while(data < tail) loop never
terminates, spinning forever in softirq context.

Reject inner IPv4 packets where tot_len < ihl*4 or ihl*4 < sizeof(struct
iphdr), which catches both the tot_len=0 case and malformed ihl values.
The normal IP stack performs this validation in ip_rcv_core(), but IPTFS
extracts and processes inner packets before they reach that layer.

regulator: mt6363: Fix incorrect and redundant IRQ disposal in probe
In mt6363_regulator_probe(), devm_add_action_or_reset() is used to
automatically dispose of the IRQ mapping if the probe fails or the
device is removed.

The manual call to irq_dispose_mapping() in the error path was redundant
as the reset action already triggers mt6363_irq_remove(). Furthermore,
the manual call incorrectly passed the hardware IRQ number (info->hwirq)
instead of the virtual IRQ mapping (info->virq).

Remove the redundant and incorrect manual disposal.

In cs35l56_process_xu_onchip_speaker_id() the warning that the number
of pulls != number of GPIOs should only be printed if pulls are defined.

Pull settings are optional because there would normally be an external
resistor providing the pull. The warning would still be true if pulls
are not defined, but in that case is just log noise.

While we're changing that block of code, also fix the indenting of the
arguments to the dev_warn().

ASoC: cs35l56: Only patch ASP registers if the DAI is part of a DAIlink
Move the ASP register patches to a separate struct and apply this from the
ASP DAI probe() function so that the registers are only patched if the DAI
is part of a DAI link.

Some systems use the ASP as a special-purpose interconnect and on these
systems the ASP registers are configured by a third party (the firmware,
the BIOS, or another device using the amp's secondary host control
interface).

If the machine driver does not hook up the ASP DAI then the ASP registers
must be omitted from the patch to prevent overwriting the third party
configuration.

If the machine driver includes the ASP DAI in a DAI link, this implies that
the machine driver and higher components (such as alsa-ucm) are taking
ownership of the ASP. In this case the ASP registers are patched to known
defaults and the machine driver should configure the ASP.

e2bd1b1369 A single fix for debugobjects.
The deferred page initialization prevents debug objects from allocating
 slab pages until the initialization is complete. That causes depletion of
 the pool and disabling of debugobjects.
 
 The reason is that debugobjects uses __GFP_HIGH for allocations as it might
 be invoked from arbitrary contexts. When PREEMPT_COUNT is disabled there is
 no way to know whether the context is safe to set __GFP_KSWAPD_RECLAIM.
 
 This worked until v6.18. Since then allocations w/o a reclaim flag cause
 new_slab() to end up in alloc_frozen_pages_nolock_noprof(), which returns
 early when deferred page initialization has not yet completed.
 
 Work around that when PREEMPT_COUNT is enabled as the preempt counter
 allows debugobjects to add __GFP_KSWAPD_RECLAIM to the GFP flags when the
 context is preemtible. When PREEMPT_COUNT is disabled the context is
 unknown and the reclaim bit can't be set because the caller might hold
 locks which might deadlock in the allocator.
 
 That makes debugobjects depend on PREEMPT_COUNT || !DEFERRED_STRUCT_PAGE_INIT,
 which limits the coverage slightly, but keeps it functional for most cases.

f6542af922 Improve the inlining of jiffies_to_msecs() and jiffies_to_usecs(),
for the common HZ=100, 250 or 1000 cases, only inlining them
 for odd HZ values like HZ=300.
 
 The inlining overhead showed up in performance tests of the TCP code.

4478e8eeb8 lib/crypto: tests: Depend on library options rather than selecting them
The convention for KUnit tests is to have the test kconfig options
visible only when the code they depend on is already enabled.  This way
only the tests that are relevant to the particular kernel build can be
enabled, either manually or via KUNIT_ALL_TESTS.

Update lib/crypto/tests/Kconfig to follow that convention, i.e. depend
on the corresponding library options rather than selecting them.  This
fixes an issue where enabling KUNIT_ALL_TESTS enabled non-test code.

This does mean that it becomes a bit more difficult to enable *all* the
crypto library tests (which is what I do as a maintainer of the code),
since doing so will now require enabling other options that select the
libraries.  Regardless, we should follow the standard KUnit convention.
I'll also add a .kunitconfig file that does enable all these options.

Note: currently most of the crypto library options are selected by
visible options in crypto/Kconfig, which can be used to enable them
without too much trouble.  If in the future we end up with more cases
like CRYPTO_LIB_CURVE25519 which is selected only by WIREGUARD (thus
making CRYPTO_LIB_CURVE25519_KUNIT_TEST effectively depend on WIREGUARD
after this commit), we could consider adding a new kconfig option that
