Add a new API to retrieve a user space callstack called
unwind_user_faultable(). The difference between this user space stack
tracer from the current user space stack tracer is that this must be
called from faultable context as it may use routines to access user space
data that needs to be faulted in.
It can be safely called from entering or exiting a system call as the code
can still be faulted in there.
This code is based on work by Josh Poimboeuf's deferred unwinding code:

Introduce a generic API for unwinding user stacks.
In order to expand user space unwinding to be able to handle more complex
scenarios, such as deferred unwinding and reading user space information,
create a generic interface that all architectures can use that support the
various unwinding methods.
This is an alternative method for handling user space stack traces from
the simple stack_trace_save_user() API. This does not replace that
interface, but this interface will be used to expand the functionality of
user space stack walking.
None of the structures introduced will be exposed to user space tooling.
Support for frame pointer unwinding is added. For an architecture to
support frame pointer unwinding it needs to enable
CONFIG_HAVE_UNWIND_USER_FP and define ARCH_INIT_USER_FP_FRAME.
By encoding the frame offsets in struct unwind_user_frame, much of this
code can also be reused for future unwinder implementations like sframe.

Pull new SoC support from Arnd Bergmann:
"These five newly supported chips come with both devicetree
descriptions and the changes to wire them up to the build system for
easier bisection.
The chips in question are:
- Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
in the product line that started with the Digital StrongARM SA1100
based PDAs and continued with the Intel PXA2xx that dominated early
smartphones. This one only made it only into a few products before
the entire product line was cut in 2015.
- The QiLai SoC is made by RISC-V core designer Andes Technologies
and is in the 'Voyager' reference board in MicroATX form factor. It
uses four in-order AX45MP cores, which is the midrange product from
Andes.
- CIX P1 is one of the few Arm chips designed for small workstations,
and this one uses 12 Cortex-A720/A520 cores, making it also one of
the only ARMv9.2 machines that one can but at the moment.
- Axiado AX3000 is an embedded chip with relative small Cortex-A53
CPU cores described as a "Trusted Control/Compute Unit" that can be
used as a BMC in servers. In addition to the usual I/O, this one
comes with 10GBit ethernet and and a 4TOPS NPU.
- Sophgo SG2000 is an embedded chip that comes with both RISC-V and
Arm cores that can run Linux. This was already supported for RISC-V
but now it also works on Arm

Pull SoC driver updates from Arnd Bergmann:
"Changes are all over the place, but very little sticks out as
noteworthy.
There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
I/O chip, along with hooking it up to the pinctrl and clk frameworks.
The reset controller and memory subsystems have mainly small updates,
but there are two new reset drivers for the K230 and VC1800B SoCs, and
new memory driver support for Tegra264.
The ARM SMCCC and SCMI firmware drivers gain a few more features that
should help them be supported across more environments. Similarly, the
SoC specific firmware on Tegra and Qualcomm get minor enhancements and
chip support.
In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
grow to support more chips, while the Hisilicon, Mediatek and Renesas
drivers see mostly janitorial fixes"

- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it
There are five more chips in a separate branch, as those are new chip
families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly added
machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and Sophgo
sg2042
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5"

pci_bridge_d3_possible() seeks to forbid runtime power management on:
* Non Hot-Plug Capable PCIe ports which are nevertheless ACPI slots
(recognizable as: bridge->is_hotplug_bridge && !bridge->is_pciehp)
* Hot-Plug Capable PCIe ports for which platform firmware has not granted
PCIe Native Hot-Plug control to the operating system
(recognizable as: bridge->is_pciehp && !pciehp_is_native(bridge))
Somewhat confusingly, the check for is_hotplug_bridge is in
pci_bridge_d3_possible(), whereas the one for is_pciehp is in
pciehp_is_native().
For clarity, check is_pciehp directly in pci_bridge_d3_possible()
(and in the other caller of pciehp_is_native(), hotplug_is_native()).
Rephrase the code comment preceding these checks to no longer mention
"System Management Mode", which is an x86 term inappropriate in generic
PCI code. Likewise no longer mention "Thunderbolt on non-Macs", because
there is nothing Thunderbolt-specific about these checks. It used to be
the case that non-Macs relied on the platform for Thunderbolt tunnel
management and hotplug, but they've since moved to OS-native tunnel
management (as Macs always have), hence the code comment is no longer
accurate.
There is a subsequent check for is_hotplug_bridge further down in
pci_bridge_d3_possible(). Change the check to is_pciehp because any
ports matching "bridge->is_hotplug_bridge && !bridge->is_pciehp" are
already filtered out at the top of the function.
Do the same for another check in acpi_pci_bridge_d3(), which is called
from pci_bridge_d3_possible() via platform_pci_bridge_d3().
No functional change intended.

The PCIe hotplug driver calculates the depth of a nested hotplug port by
looking at the is_hotplug_bridge flag. The depth is used as lockdep class
to tell hotplug ports apart.
The is_hotplug_bridge flag encompasses ACPI slots handled by the ACPI
hotplug driver, hence the calculated depth may be too high. Avoid by
checking the is_pciehp flag instead.
This glitch likely has no user-visible impact: ACPI slots typically only
exist at the Root Port level, not in nested hotplug hierarchies. Also,
CONFIG_LOCKDEP is usually only used by developers. So this is just for
the sake of correctness.

The PCIe port driver erroneously creates a subdevice for hotplug on ACPI
slots which are handled by the ACPI hotplug driver.
Avoid by checking the is_pciehp flag instead of is_hotplug_bridge when
deciding whether to create a subdevice. The latter encompasses ACPI slots
whereas the former doesn't.
The superfluous subdevice has no real negative impact, it occupies memory
and interrupt resources but otherwise just sits there waiting for
interrupts from the slot that are never signaled.

pci_bridge_d3_possible() is called from both pcie_portdrv_probe() and
pcie_portdrv_remove() to determine whether runtime power management shall
be enabled (on probe) or disabled (on remove) on a PCIe port.
The underlying assumption is that pci_bridge_d3_possible() always returns
the same value, else a runtime PM reference imbalance would occur. That
assumption is not given if the PCIe port is inaccessible on remove due to
hot-unplug: pci_bridge_d3_possible() calls pciehp_is_native(), which
accesses Config Space to determine whether the port is Hot-Plug Capable.
An inaccessible port returns "all ones", which is converted to "all
zeroes" by pcie_capability_read_dword(). Hence the port no longer seems
Hot-Plug Capable on remove even though it was on probe.
The resulting runtime PM ref imbalance causes warning messages such as:
pcieport 0000:02:04.0: Runtime PM usage count underflow!
Avoid the Config Space access (and thus the runtime PM ref imbalance) by
caching the Hot-Plug Capable bit in struct pci_dev.
The struct already contains an "is_hotplug_bridge" flag, which however is
not only set on Hot-Plug Capable PCIe ports, but also Conventional PCI
Hot-Plug bridges and ACPI slots. The flag identifies bridges which are
allocated additional MMIO and bus number resources to allow for hierarchy
expansion.
The kernel is somewhat sloppily using "is_hotplug_bridge" in a number of
places to identify Hot-Plug Capable PCIe ports, even though the flag
encompasses other devices. Subsequent commits replace these occurrences
with the new flag to clearly delineate Hot-Plug Capable PCIe ports from
other kinds of hotplug bridges.
Document the existing "is_hotplug_bridge" and the new "is_pciehp" flag
and document the (non-obvious) requirement that pci_bridge_d3_possible()
always returns the same value across the entire lifetime of a bridge,
including its hot-removal.

With CONFIG_DEBUG_INFO_BTF=y and PAHOLE_HAS_BTF_TAG=y, `__user` is
converted to `__attribute__((btf_type_tag("user")))`. In this case,
some syscall events have it for __user data, like below;
/sys/kernel/tracing # cat events/syscalls/sys_enter_openat/format
name: sys_enter_openat
ID: 720
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:int __syscall_nr; offset:8; size:4; signed:1;
field:int dfd; offset:16; size:8; signed:0;
field:const char __attribute__((btf_type_tag("user"))) * filename; offset:24; size:8; signed:0;
field:int flags; offset:32; size:8; signed:0;
field:umode_t mode; offset:40; size:8; signed:0;
Then the trace event filter fails to set the string acceptable flag
(FILTER_PTR_STRING) to the field and rejects setting string filter;
# echo 'filename.ustring ~ "*ftracetest-dir.wbx24v*"' \
>> events/syscalls/sys_enter_openat/filter
sh: write error: Invalid argument
# cat error_log
[ 723.743637] event filter parse error: error: Expecting numeric field
Command: filename.ustring ~ "*ftracetest-dir.wbx24v*"
Since this __attribute__ makes format parsing complicated and not
needed, remove the __attribute__(.*) from the type string.

KVM/arm64 changes for 6.17, round #1
- Host driver for GICv5, the next generation interrupt controller for
arm64, including support for interrupt routing, MSIs, interrupt
translation and wired interrupts.
- Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
GICv5 hardware, leveraging the legacy VGIC interface.
- Userspace control of the 'nASSGIcap' GICv3 feature, allowing
userspace to disable support for SGIs w/o an active state on hardware
that previously advertised it unconditionally.
- Map supporting endpoints with cacheable memory attributes on systems
with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
maintenance on the address range.
- Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
hypervisor to inject external aborts into an L2 VM and take traps of
masked external aborts to the hypervisor.
- Convert more system register sanitization to the config-driven
implementation.
- Fixes to the visibility of EL2 registers, namely making VGICv3 system
registers accessible through the VGIC device instead of the ONE_REG
vCPU ioctls.
- Various cleanups and minor fixes.

As per the i.MX93 TRM, section 67.3.2.1 "MOD register update", the value
of the TPM counter does NOT get updated when writing MOD.MOD unless
SC.CMOD != 0. Therefore, with the current code, assuming the following
sequence:
1) pwm_disable()
2) pwm_apply_might_sleep() /* period is changed here */
3) pwm_enable()
and assuming only one channel is active, if CNT.COUNT is higher than the
MOD.MOD value written during the pwm_apply_might_sleep() call then, when
re-enabling the PWM during pwm_enable(), the counter will end up resetting
after UINT32_MAX - CNT.COUNT + MOD.MOD cycles instead of MOD.MOD cycles as
normally expected.
Fix this problem by forcing a reset of the TPM counter before MOD.MOD is
written.

The period generated by the hardware is
(PWMDWIDTH + 1) << CLKDIV) / freq
according to my tests with a signal analyser and also the documentation.
The current algorithm doesn't consider the `+ 1` part and so configures
slightly too high periods. The same issue exists for the duty cycle
setting. So subtract 1 from both the register values for period and
duty cycle. If period is 0, bail out, if duty_cycle is 0, just disable
the PWM which results in a constant low output.

Stop handling the clocks in pwm_mediatek_enable() and
pwm_mediatek_disable(). This is a preparing change for the next commit
that requires that clocks and the enable bit are handled separately.
Also move these two functions a bit further up in the source file to
make them usable in pwm_mediatek_config(), which is needed in the next
commit, too.

The logic in regulator_set_voltage() which checks for a non-convergence
condition on a stepped regulator is flawed.
regulator_set_voltage() checks if the error in target voltage has increased
or decreased, and returns -EWOULDBLOCK if the error has not decreased
enough. The correct non-convergence condition is:
new_delta - delta > -rdev->constraints->max_uV_step
or equivalently:
delta - new_delta < rdev->constraints->max_uV_step
But the currently used condition is:
new_delta - delta > rdev->constraints->max_uV_step
Which may cause an infinite loop if the voltage error doesn't converge.
Fix this by correcting the convergence condition.

In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO
without calling release_metapage() to decrease the reference count,
leading to a memory leak.
Add release_metapage(mp) before the error return to properly manage
the metapage reference count and prevent the leak.

When testing a series of commits that also includes changes to the Linux
tools directory, it is useless to test the changes in tools as they may
not affect the kernel itself. Doing tests on the kernel for changes that
do not affect the kernel is a waste of time.
Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped
while doing the individual commit tests.
For example, the runtime verification may have a series of commits like:
$ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD
3d3800b4f7f4 rv: Remove rv_reactor's reference counter
3d3c376118b5 rv: Merge struct rv_reactor_def into struct rv_reactor
24cbfe18d55a rv: Merge struct rv_monitor_def into struct rv_monitor
b0c08dd5348d rv: Remove unused field in struct rv_monitor_def
58d5f0d437a8 (debiantesting-x86-64/trace/rv/core) rv: Return init error when registering monitors
560473f2e2d7 verification/rvgen: Organise Kconfig entries for nested monitors
9efcf590827c tools/dot2c: Fix generated files going over 100 column limit
1160ccaf772f tools/rv: Stop gracefully also on SIGTERM
f60227f34489 tools/rv: Do not skip idle in trace
f3735df6281e verification/rvgen: Do not generate unused variables
6fb37c2a27eb verification/rvgen: Generate each variable definition only once
8cfcf9b0e92f verification/rvgen: Support the 'next' operator
fac5493251a6 rv: Allow to configure the number of per-task monitor
Where the first commit touches the kernel followed by a series of commits
that do not, and ends with commits that do. Instead of having to add
multiple patchcheck tests to handle the gaps, just include the commits
that should not be tested:
$ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD |
grep -e verification -e tools/ | cut -d' ' -f1 |
while read a ; do echo -n "$a "; done
560473f2e2d7 9efcf590827c 1160ccaf772f f60227f34489 f3735df6281e 6fb37c2a27eb 8cfcf9b0e92f
Then set PATCHCHECK_SKIP to that, and those commits will be skipped.
PATCHCHECK_SKIP = 560473f2e2d7 9efcf590827c 1160ccaf772f f60227f34489 f3735df6281e 6fb37c2a27eb 8cfcf9b0e92f

KVM SEV cache maintenance changes for 6.17
- Drop a superfluous WBINVD (on all CPUs!) when destroying a VM.
- Use WBNOINVD instead of WBINVD when possible, for SEV cache maintenance,
e.g. to minimize collateral damage when reclaiming memory from an SEV guest.
- When reclaiming memory from an SEV guest, only do cache flushes on CPUs that
have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs
that can't possibly have cache lines with dirty, encrypted data.

KVM SVM changes for 6.17
Drop KVM's rejection of SNP's SMT and single-socket policy restrictions, and
instead rely on firmware to verify that the policy can actually be supported.
Don't bother checking that requested policy(s) can actually be satisfied, as
an incompatible policy doesn't put the kernel at risk in any way, and providing
guarantees with respect to the physical topology is outside of KVM's purview.

|
KVM selftests changes for 6.17
- Fix a comment typo.
- Verify KVM is loaded when getting any KVM module param so that attempting to
run a selftest without kvm.ko loaded results in a SKIP message about KVM not
being loaded/enabled, versus some random parameter not existing.
- SKIP tests that hit EACCES when attempting to access a file, with a "Root
required?" help message. In most cases, the test just needs to be run with
elevated permissions.

KVM local APIC changes for 6.17

KVM x86 MMU changes for 6.17
- Exempt nested EPT from the the !USER + CR0.WP logic, as EPT doesn't interact

- Move the TDX hardware setup code to tdx.c to better co-locate TDX code
and eliminate a few global symbols.
- Dynamically allocation the shadow MMU's hashed page list, and defer
allocating the hashed list until it's actually needed (the TDP MMU doesn't
use the list).

KVM x86 misc changes for 6.17
- Prevert the host's DEBUGCTL.FREEZE_IN_SMM (Intel only) when running the
guest. Failure to honor FREEZE_IN_SMM can bleed host state into the guest.
- Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter (Intel only) to
prevent L1 from running L2 with features that KVM doesn't support, e.g. BTF.
- Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the
vCPU's CPUID model.
- Rework the MSR interception code so that the SVM and VMX APIs are more or
less identical.
- Recalculate all MSR intercepts from the "source" on MSR filter changes, and
drop the dedicated "shadow" bitmaps (and their awful "max" size defines).
- WARN and reject loading kvm-amd.ko instead of panicking the kernel if the
nested SVM MSRPM offsets tracker can't handle an MSR.
- Advertise support for LKGS (Load Kernel GS base), a new instruction that's
loosely related to FRED, but is supported and enumerated independently.
- Fix a user-triggerable WARN that syzkaller found by stuffing INIT_RECEIVED,
a.k.a. WFS, and then putting the vCPU into VMX Root Mode (post-VMXON). Use
the same approach KVM uses for dealing with "impossible" emulation when
running a !URG guest, and simply wait until KVM_RUN to detect that the vCPU
has architecturally impossible state.
- Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of
APERF/MPERF reads, so that a "properly" configured VM can "virtualize"
APERF/MPERF (with many caveats).
- Reject KVM_SET_TSC_KHZ if vCPUs have been created, as changing the "default"
frequency is unsupported for VMs with a "secure" TSC, and there's no known
use case for changing the default frequency for other VM types.

KVM MMIO Stale Data mitigation cleanup for 6.17
Rework KVM's mitigation for the MMIO State Data vulnerability to track
whether or not a vCPU has access to (host) MMIO based on the MMU that will be
used when running in the guest. The current approach doesn't actually detect
whether or not a guest has access to MMIO, and is prone to false negatives (and
to a lesser extent, false positives), as KVM_DEV_VFIO_FILE_ADD is optional, and
obviously only covers VFIO devices.
