ACPI: button: trigger wakeup key events

Andorid can wakeup from various wakeup sources, but only several wakeup
sources can wake up screen with right events(POWER, WAKEUP) from input
device.

Regarding pressing acpi power button, it can resume system and
ACPI_BITMASK_WAKE_STATUS and ACPI_BITMASK_POWER_BUTTON_STATUS are set in
pm1a_sts, but kernel does not report any key event to user space during
resuming by default.

So, send wakeup key event to user space during resume from power button.

ACPI: EC: Use a spin lock without disabing interrupts

Since all of the ACPI EC driver code runs in thread context after recent
changes, it does not need to disable interrupts on the local CPU when
acquiring a spin lock.

Make it use the spin lock without disabling interrupts.

ACPI: EC: Use a threaded handler for dedicated IRQ

After commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler
for SCI") all of the EC code runs in thread context on all systems where
EC events are signaled through a GPE.

It may as well run in thread context on systems using a dedicated IRQ
for EC events signaling, so make it use a threaded handler for that IRQ.

ACPI: OSL: Use spin locks without disabling interrupts

After commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler

not dissable interrupts on the local CPU when acquiring a spin lock.

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.

While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

debugfs: initialize cancellations earlier

Tetsuo Handa pointed out that in the (now reverted)
lockdep commit I initialized the data too late. The
same is true for the cancellation data, it must be
initialized before the cmpxchg(), otherwise it may
be done twice and possibly even overwriting data in
there already when there's a race. Fix that, which
also requires destroying the mutex in case we lost
the race.

"Some driver fixes for v6.7, all are in drivers, the most interesting
  one is probably the AMD laptop suspend bug which really needs fixing.
  Freedestop org has the bug description:

    https://gitlab.freedesktop.org/drm/amd/-/issues/2812

  Summary:

   - Ignore disabled device tree nodes in the Starfive 7100 and 7100
     drivers.

   - Mask non-wake source pins with interrupt enabled at suspend in the
     AMD driver, this blocks unnecessary wakeups from misc interrupts.
     This can be power consuming because in many cases the system
     doesn't really suspend, it just wakes right back up.

   - Fix a typo breaking compilation of the cy8c95x0 driver, and fix up
     bugs in the get/set config callbacks.

   - Use a dedicated lock class for the PIO4 drivers IRQ. This fixes a
     crash on suspend"

afs: Fix use-after-free due to get/remove race in volume tree

When an afs_volume struct is put, its refcount is reduced to 0 before
the cell->volume_lock is taken and the volume removed from the
cell->volumes tree.

Unfortunately, this means that the lookup code can race and see a volume
with a zero ref in the tree, resulting in a use-after-free:

    refcount_t: addition on 0; use-after-free.
    WARNING: CPU: 3 PID: 130782 at lib/refcount.c:25 refcount_warn_saturate+0x7a/0xda

Fix this by:

(1) When putting, use a flag to indicate if the volume has been removed
     from the tree and skip the rb_erase if it has.

(2) When looking up, use a conditional ref increment and if it fails
     because the refcount is 0, replace the node in the tree and set the
     removal flag.

ida: Fix crash in ida_free when the bitmap is empty

The IDA usually detects double-frees, but that detection failed to
consider the case when there are no nearby IDs allocated and so we have a
NULL bitmap rather than simply having a clear bit. Add some tests to the
test-suite to be sure we don't inadvertently reintroduce this problem.
Unfortunately they're quite noisy so include a message to disregard
the warnings.

afs: Fix overwriting of result of DNS query

In afs_update_cell(), ret is the result of the DNS lookup and the errors
are to be handled by a switch - however, the value gets clobbered in
between by setting it to -ENOMEM in case afs_alloc_vlserver_list()
fails.

Fix this by moving the setting of -ENOMEM into the error handling for
OOM failure. Further, only do it if we don't have an alternative error
to return.

tracing / synthetic: Disable events after testing in synth_event_gen_test_init()

The synth_event_gen_test module can be built in, if someone wants to run
the tests at boot up and not have to load them.

The synth_event_gen_test_init() function creates and enables the synthetic
events and runs its tests.

The synth_event_gen_test_exit() disables the events it created and
destroys the events.

If the module is builtin, the events are never disabled. The issue is, the
events should be disable after the tests are run. This could be an issue
if the rest of the boot up tests are enabled, as they expect the events to
be in a known state before testing. That known state happens to be
disabled.

When CONFIG_SYNTH_EVENT_GEN_TEST=y and CONFIG_EVENT_TRACE_STARTUP_TEST=y
a warning will trigger:

Running tests on trace events:
Testing event create_synth_test:
Enabled event during self test!

eventfs: Have event files and directories default to parent uid and gid

Dongliang reported:

  I found that in the latest version, the nodes of tracefs have been
  changed to dynamically created.

  This has caused me to encounter a problem where the gid I specified in
  the mounting parameters cannot apply to all files, as in the following
  situation:

  /data/tmp/events # mount | grep tracefs
  tracefs on /data/tmp type tracefs (rw,seclabel,relatime,gid=3012)

  gid 3012 = readtracefs

  /data/tmp # ls -lh
  total 0
  -r--r-----   1 root readtracefs 0 1970-01-01 08:00 README
  -r--r-----   1 root readtracefs 0 1970-01-01 08:00 available_events

  drwxr-xr-x 2 root root 0 2023-12-19 00:56 asoc

  It will prevent certain applications from accessing tracefs properly, I
  try to avoid this issue by making the following modifications.

To fix this, have the files created default to taking the ownership of
the parent dentry unless the ownership was previously set by the user.

ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on synchronous events

There are two major types of uncorrected recoverable (UCR) errors :

- Synchronous error: The error is detected and raised at the point of
   the consumption in the execution flow, e.g. when a CPU tries to
   access a poisoned cache line. The CPU will take a synchronous error
   exception such as Synchronous External Abort (SEA) on Arm64 and
   Machine Check Exception (MCE) on X86. OS requires to take action (for
   example, offline failure page/kill failure thread) to recover this
   uncorrectable error.

- Asynchronous error: The error is detected out of processor execution
   context, e.g. when an error is detected by a background scrubber.
   Some data in the memory are corrupted. But the data have not been
   consumed. OS is optional to take action to recover this uncorrectable
   error.

When APEI firmware first is enabled, a platform may describe one error
source for the handling of synchronous errors (e.g. MCE or SEA notification
), or for handling asynchronous errors (e.g. SCI or External Interrupt
notification). In other words, we can distinguish synchronous errors by
APEI notification. For synchronous errors, kernel will kill the current
process which accessing the poisoned page by sending SIGBUS with
BUS_MCEERR_AR. In addition, for asynchronous errors, kernel will notify the
process who owns the poisoned page by sending SIGBUS with BUS_MCEERR_AO in
early kill mode. However, the GHES driver always sets mf_flags to 0 so that
all synchronous errors are handled as asynchronous errors in memory failure.

To this end, set memory failure flags as MF_ACTION_REQUIRED on synchronous
events.

keys, dns: Allow key types (eg. DNS) to be reclaimed immediately on expiry

If a key has an expiration time, then when that time passes, the key is
left around for a certain amount of time before being collected (5 mins by
default) so that EKEYEXPIRED can be returned instead of ENOKEY.  This is a
problem for DNS keys because we want to redo the DNS lookup immediately at
that point.

Fix this by allowing key types to be marked such that keys of that type
don't have this extra period, but are reclaimed as soon as they expire and
turn this on for dns_resolver-type keys.  To make this easier to handle,
key->expiry is changed to be permanent if TIME64_MAX rather than 0.

Furthermore, give such new-style negative DNS results a 1s default expiry
if no other expiry time is set rather than allowing it to stick around
indefinitely.  This shouldn't be zero as ls will follow a failing stat call
immediately with a second with AT_SYMLINK_NOFOLLOW added.

gpio: dwapb: mask/unmask IRQ when disable/enale it

In the hardware implementation of the I2C HID driver based on DesignWare
GPIO IRQ chip, when the user continues to use the I2C HID device in the
suspend process, the I2C HID interrupt will be masked after the resume
process is finished.

This is because the disable_irq()/enable_irq() of the DesignWare GPIO
driver does not synchronize the IRQ mask register state. In normal use
of the I2C HID procedure, the GPIO IRQ irq_mask()/irq_unmask() functions
are called in pairs. In case of an exception, i2c_hid_core_suspend()
calls disable_irq() to disable the GPIO IRQ. With low probability, this
causes irq_unmask() to not be called, which causes the GPIO IRQ to be
masked and not unmasked in enable_irq(), raising an exception.

Add synchronization to the masked register state in the
dwapb_irq_enable()/dwapb_irq_disable() function. mask the GPIO IRQ
before disabling it. After enabling the GPIO IRQ, unmask the IRQ.

gpiolib: cdev: add gpio_device locking wrapper around gpio_ioctl()

While the GPIO cdev gpio_ioctl() call is in progress, the kernel can
call gpiochip_remove() which will set gdev->chip to NULL, after which
any subsequent access will cause a crash.

gpio_ioctl() was overlooked by the previous fix to protect syscalls
(bdbbae241a04), so add protection for that.

net: check dev->gso_max_size in gso_features_check()

Some drivers might misbehave if TSO packets get too big.

GVE for instance uses a 16bit field in its TX descriptor,
and will do bad things if a packet is bigger than 2^16 bytes.

Linux TCP stack honors dev->gso_max_size, but there are
other ways for too big packets to reach an ndo_start_xmit()
handler : virtio_net, af_packet, GRO...

Add a generic check in gso_features_check() and fallback
to GSO when needed.

gso_max_size was added in the blamed commit.

This warning is raised because pinctrl-at91-pio4 uses chained IRQ. Whenever
a wake up source configures an IRQ through irq_set_irq_wake, it will
lock the corresponding IRQ desc, and then call irq_set_irq_wake on "parent"
IRQ which will do the same on its own IRQ desc, but since those two locks
share the same class, lockdep reports this as an issue.

Fix lockdep false positive by setting a different class for parent and
children IRQ

x86/xen: add CPU dependencies for 32-bit build

Xen only supports modern CPUs even when running a 32-bit kernel, and it now
requires a kernel built for a 64 byte (or larger) cache line:

  166 |         BUILD_BUG_ON(sizeof(*vcpup) > SMP_CACHE_BYTES);
      |         ^~~~~~~~~~~~

Enforce the dependency with a whitelist of CPU configurations. In normal
distro kernels, CONFIG_X86_GENERIC is enabled, and this works fine. When this
is not set, still allow Xen to be built on kernels that target a 64-bit
capable CPU.

net: avoid build bug in skb extension length calculation

GCC seems to incorrectly fail to evaluate skb_ext_total_length() at
compile time under certain conditions.

The issue even occurs if all values in skb_ext_type_len[] are "0",
ruling out the possibility of an actual overflow.

As the patch has been in mainline since v6.6 without triggering the
problem it seems to be a very uncommon occurrence.

As the issue only occurs when -fno-tree-loop-im is specified as part of
CFLAGS_GCOV, disable the BUILD_BUG_ON() only when building with coverage
reporting enabled.

posix-timers: Get rid of [COMPAT_]SYS_NI() uses

Only the posix timer system calls use this (when the posix timer support

they had debug code to print out a warning about missing system calls.

Get rid of that special case, and just use the standard COND_SYSCALL
interface that creates weak system call stubs that return -ENOSYS for
when the system call does not exist.

afs: Fix dynamic root lookup DNS check

In the afs dynamic root directory, the ->lookup() function does a DNS check
on the cell being asked for and if the DNS upcall reports an error it will
report an error back to userspace (typically ENOENT).

However, if a failed DNS upcall returns a new-style result, it will return
a valid result, with the status field set appropriately to indicate the
type of failure - and in that case, dns_query() doesn't return an error and
we let stat() complete with no error - which can cause confusion in
userspace as subsequent calls that trigger d_automount then fail with
ENOENT.

Fix this by checking the status result from a valid dns_query() and
returning an error if it indicates a failure.

bcachefs: Fix bch2_alloc_sectors_start_trans() error handling

When we fail to allocate because of insufficient open buckets, we don't
want to retry from the full set of devices - we just want to retry in
blocking mode.

But if the retry in blocking mode fails with a different error code, we
end up squashing the -BCH_ERR_open_buckets_empty error with an error
that makes us thing we won't be able to allocate (insufficient_devices)
- which is incorrect when we didn't try to allocate from the full set of
devices, and causes the write to fail.

Pull tracing fix from Steven Rostedt:
"While working on the ring buffer, I found one more bug with the
  timestamp code, and the fix for this removed the need for the final
  64-bit cmpxchg!

  The ring buffer events hold a "delta" from the previous event. If it
  is determined that the delta can not be calculated, it falls back to
  adding an absolute timestamp value. The way to know if the delta can
  be used is via two stored timestamps in the per-cpu buffer meta data:

   before_stamp and write_stamp

  The before_stamp is written by every event before it tries to allocate
  its space on the ring buffer. The write_stamp is written after it
  allocates its space and knows that nothing came in after it read the
  previous before_stamp and write_stamp and the two matched.

  A previous fix dd9394257078 ("ring-buffer: Do not try to put back
  write_stamp") removed putting back the write_stamp to match the
  before_stamp so that the next event could use the delta, but races
  were found where the two would match, but not be for of the previous
  event.

  It was determined to allow the event reservation to not have a valid
  write_stamp when it is finished, and this fixed a lot of races.

  The last use of the 64-bit timestamp cmpxchg depended on the
  write_stamp being valid after an interruption. But this is no longer
  the case, as if an event is interrupted by a softirq that writes an
  event, and that event gets interrupted by a hardirq or NMI and that
  writes an event, then the softirq could finish its reservation without
  a valid write_stamp.

  In the slow path of the event reservation, a delta can still be used
  if the write_stamp is valid. Instead of using a cmpxchg against the
  write stamp, the before_stamp needs to be read again to validate the
  write_stamp. The cmpxchg is not needed.

  This updates the slowpath to validate the write_stamp by comparing it
  to the before_stamp and removes all rb_time_cmpxchg() as there are no
  more users of that function.

  The removal of the 32-bit updates of rb_time_t will be done in the
  next merge window"

drm/amdkfd: svm range always mapped flag not working on APU

On gfx943 APU there is no VRAM and page migration, queue CWSR area, svm
range with always mapped flag, is not mapped to GPU correctly. This
works fine if retry fault on CWSR area can be recovered, but could cause
deadlock if there is another retry fault recover waiting for CWSR to
finish.

Fix this by mapping svm range with always mapped flag to GPU with ACCESS
attribute if XNACK ON.

There is side effect, because all GPUs have ACCESS attribute by default
on new svm range with XNACK on, the CWSR area will be mapped to all GPUs
after this change. This side effect will be fixed with Thunk change to
set CWSR svm range with ACCESS_IN_PLACE attribute on the GPU that user
