The vboxguest driver depends on port I/O for debug output:

102 | outl(phys_req, gdev->io_port + VMMDEV_PORT_OFF_REQUEST);
| ^~~~
Most arm64 platforms don't actually support port I/O, though it is
currently enabled unconditionally. Refine the vbox dependency to allow
turning HAS_IOPORT off in the future when building for platforms without
port I/O and allow compile-testing on all architectures.

Fixed a possible UAF problem in driver_override_show() in drivers/cdx/cdx.c
This function driver_override_show() is part of DEVICE_ATTR_RW, which
includes both driver_override_show() and driver_override_store().
These functions can be executed concurrently in sysfs.
The driver_override_store() function uses driver_set_override() to
update the driver_override value, and driver_set_override() internally
locks the device (device_lock(dev)). If driver_override_show() reads
cdx_dev->driver_override without locking, it could potentially access
a freed pointer if driver_override_store() frees the string
concurrently. This could lead to printing a kernel address, which is a
security risk since DEVICE_ATTR can be read by all users.
Additionally, a similar pattern is used in drivers/amba/bus.c, as well
as many other bus drivers, where device_lock() is taken in the show
function, and it has been working without issues.
This potential bug was detected by our experimental static analysis
tool, which analyzes locking APIs and paired functions to identify
data races and atomicity violations.

There are multiple places from where the recovery work gets scheduled
asynchronously. Also, there are multiple places where the caller waits
synchronously for the recovery to be completed. One such place is during
the PM shutdown() callback.
If the device is not alive during recovery_work, it will try to reset the
device using pci_reset_function(). This function internally will take the
device_lock() first before resetting the device. By this time, if the lock
has already been acquired, then recovery_work will get stalled while
waiting for the lock. And if the lock was already acquired by the caller
which waits for the recovery_work to be completed, it will lead to
deadlock.
This is what happened on the X1E80100 CRD device when the device died
before shutdown() callback. Driver core calls the driver's shutdown()
callback while holding the device_lock() leading to deadlock.
And this deadlock scenario can occur on other paths as well, like during
the PM suspend() callback, where the driver core would hold the
device_lock() before calling driver's suspend() callback. And if the
recovery_work was already started, it could lead to deadlock. This is also
observed on the X1E80100 CRD.
So to fix both issues, use pci_try_reset_function() in recovery_work. This
function first checks for the availability of the device_lock() before
trying to reset the device. If the lock is available, it will acquire it
and reset the device. Otherwise, it will return -EAGAIN. If that happens,
recovery_work will fail with the error message "Recovery failed" as not
much could be done.

The _CRS ACPI resources table has 2 entries for the host wakeup GPIO,
the first one being a regular GpioIo () resource while the second one
is a GpioInt () resource for the same pin.
The acpi_gpio_mapping table used by vsc-tp.c maps the first Gpio ()
resource to "wakeuphost-gpios" where as the second GpioInt () entry
is mapped to "wakeuphostint-gpios".
Using "wakeuphost" to request the GPIO as was done until now, means
that the gpiolib-acpi code does not know that the GPIO is active-low
as that info is only available in the GpioInt () entry.
Things were still working before due to the following happening:
1. Since the 2 entries point to the same pin they share a struct gpio_desc
2. The SPI core creates the SPI device vsc-tp.c binds to and calls
acpi_dev_gpio_irq_get(). This does use the second entry and sets
FLAG_ACTIVE_LOW in gpio_desc.flags .
3. vsc_tp_probe() requests the "wakeuphost" GPIO and inherits the
active-low flag set by acpi_dev_gpio_irq_get()
But there is a possible scenario where things do not work:
1. - 3. happen as above
4. After requesting the "wakeuphost" GPIO, the "resetfw" GPIO is requested
next, but its USB GPIO controller is not available yet, so this call
returns -EPROBE_DEFER.
5. The gpio_desc for "wakeuphost" is put() and during this the active-low
flag is cleared from gpio_desc.flags .
6. Later on vsc_tp_probe() requests the "wakeuphost" GPIO again, but now it
is not marked active-low.
The difference can also be seen in /sys/kernel/debug/gpio, which contains
the following line for this GPIO:
gpio-535 ( |wakeuphost ) in hi IRQ ACTIVE LOW
If the second scenario is hit the "ACTIVE LOW" at the end disappears and
things do not work.
Fix this by requesting the GPIO through the "wakeuphostint" mapping instead
which provides active-low info without relying on acpi_dev_gpio_irq_get()
pre-populating this info in the gpio_desc.

"Fix a recently introduced kernel crash due to a NULL pointer

* tag 'pm-6.14-rc2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: sleep: core: Restrict power.set_active propagation
|
|
Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.
The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that. As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.
Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.
To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.

When a weak pull-up is present on the SDO line, regmap_update_bits fails
to write both the SOFTRESET and SDOACTIVE bits because it incorrectly
reads them as already set.
Since the soft reset disables the SDO line, performing a
read-modify-write operation on ADI_SPI_CONFIG_A to enable the SDO line
doesn't make sense. This change directly writes to the register instead
of using regmap_update_bits.

Pull vfs fixes from Christian Brauner:
- Fix fsnotify FMODE_NONOTIFY* handling.
This also disables fsnotify on all pseudo files by default apart from
very select exceptions. This carries a regression risk so we need to
watch out and adapt accordingly. However, it is overall a significant
improvement over the current status quo where every rando file can
get fsnotify enabled.
- Cleanup and simplify lockref_init() after recent lockref changes.
- Fix vboxfs build with gcc-15.
- Add an assert into inode_set_cached_link() to catch corrupt links.
- Allow users to also use an empty string check to detect whether a
given mount option string was empty or not.
- Fix how security options were appended to statmount()'s ->mnt_opt
field.
- Fix statmount() selftests to always check the returned mask.
- Fix uninitialized value in vfs_statx_path().
- Fix pidfs_ioctl() sanity checks to guard against ioctl() overloading
and preserve extensibility.

The FMODE_NONOTIFY_* bits are a 2-bits mode. Open coding manipulation
of those bits is risky. Use an accessor file_set_fsnotify_mode() to
set the mode.
Rename file_set_fsnotify_mode() => file_set_fsnotify_mode_from_watchers()
to make way for the simple accessor name.

Commit 1db806ec06b7 ("PCI/ASPM: Save parent L1SS config in
pci_save_aspm_l1ss_state()") aimed to perform L1SS config save for both the
Upstream Port and its upstream bridge when handling an Upstream Port, which
matches what the L1SS restore side does. However, parent->state_saved can
be set true at an earlier time when the upstream bridge saved other parts
of its state. Then later when attempting to save the L1SS config while
handling the Upstream Port, parent->state_saved is true in
pci_save_aspm_l1ss_state() resulting in early return and skipping saving
bridge's L1SS config because it is assumed to be already saved. Later on
restore, junk is written into L1SS config which causes issues with some
devices.
Remove parent->state_saved check and unconditionally save L1SS config also
for the upstream bridge from an Upstream Port which ought to be harmless
from correctness point of view. With the Upstream Port check now present,
saving the L1SS config more than once for the bridge is no longer a problem
(unlike when the parent->state_saved check got introduced into the fix
during its development).

This reverts commit 8865d22656b4, which caused breakage for platforms
which are not using xgmac2 or gmac4. Only these two cores have the
capability of providing the FIFO sizes from hardware capability fields
(which are provided in priv->dma_cap.[tr]x_fifo_size.)
All other cores can not, which results in these two fields containing
zero. We also have platforms that do not provide a value in
priv->plat->[tr]x_fifo_size, resulting in these also being zero.
This causes the new tests introduced by the reverted commit to fail,
and produce e.g.:
stmmaceth f0804000.eth: Can't specify Rx FIFO size
An example of such a platform which fails is QEMU's npcm750-evb.
This uses dwmac1000 which, as noted above, does not have the capability
to provide the FIFO sizes from hardware.
Therefore, revert the commit to maintain compatibility with the way
the driver used to work.

This reverts commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3.
The blamed commit caused a regression when neither tun->owner nor
tun->group is set. This is intended to be allowed, but now requires
CAP_NET_ADMIN.
Discussion in the referenced thread pointed out that the original
issue that prompted this patch can be resolved in userspace.
The relaxed access control may also make a device accessible when it
previously wasn't, while existing users may depend on it to not be.
This is a clean pure git revert, except for fixing the indentation on
the gid_valid line that checkpatch correctly flagged.

Commit 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM

causing the PRM module to fail in translating memory error addresses.

While analysing code for software and OF node for the corner case when
caller asks to read zero items in the supposed to be an array of values
I found that ACPI behaves differently to what OF does, i.e.
1. It returns -EINVAL when caller asks to read zero items from integer
array, while OF returns 0, if no other errors happened.
2. It returns -EINVAL when caller asks to read zero items from string
array, while OF returns -ENODATA, if no other errors happened.
Amend ACPI implementation to follow what OF does.

Compile-testing without CONFIG_OF leads to a harmless build warning:
drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=]
109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = {
| ^~~~~~~~~~~~~~~~~~~~~~~~~
It would be possible to mark the variable as __maybe_unused to shut up
that warning, but a Kconfig dependency seems more appropriate as this still
allows build testing in allmodconfig and randconfig builds on all
architectures.
An earlier commit, b865a8404642 ("cpufreq: airoha: Depends on OF"),
tried to fix it incorrectly. ARCH_AIROHA already requires CONFIG_OF, so
this change does nothing, and the dependency is still missing for the
COMPILE_TEST case.
