crash, powerpc: default to CRASH_DUMP=n on PPC_BOOK3S_32
Fixes boot failures on 6.9 on PPC_BOOK3S_32 machines using Open Firmware.
On these machines, the kernel refuses to boot from non-zero
PHYSICAL_START, which occurs when CRASH_DUMP is on.
Since most PPC_BOOK3S_32 machines boot via Open Firmware, it should
default to off for them. Users booting via some other mechanism can still
turn it on explicitly.
Does not change the default on any other architectures for the
time being.

Pull SoC fixes from Arnd Bergmann: "Where the last set of fixes was mostly drivers, this time the devicetree changes all come at once, targeting mostly the Rockchips, Qualcomm and NXP platforms. The Qualcomm bugfixes target the Snapdragon X Elite laptops, specifically problems with PCIe and NVMe support to improve reliability, and a boot regresion on msm8939. Also for Snapdragon platforms, there are a number of correctness changes in the several platform specific device drivers, but none of these are as impactful. On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants, correcting individual entries in the devicetree that were incorrect and causing the media, video, mmc and spi drivers to misbehave in minor ways. The Arm SCMI firmware driver gets fixes for a use-after-free bug and for correctly parsing firmware information. On the RISC-V side, there are three minor devicetree fixes for starfive and sophgo, again addressing only minor mistakes.

riscv: Prevent a bad reference count on CPU nodes
When populating cache leaves we previously fetched the CPU device node
at the very beginning. But when ACPI is enabled we go through a
specific branch which returns early and does not call 'of_node_put' for
the node that was acquired.
Since we are not using a CPU device node for the ACPI code anyways, we
can simply move the initialization of it just passed the ACPI block, and
we are guaranteed to have an 'of_node_put' call for the acquired node.
This prevents a bad reference count of the CPU device node.
Moreover, the previous function did not check for errors when acquiring
the device node, so a return -ENOENT has been added for that case.

riscv: efi: Set NX compat flag in PE/COFF header
The IMAGE_DLLCHARACTERISTICS_NX_COMPAT informs the firmware that the
EFI binary does not rely on pages that are both executable and
writable.
The flag is used by some distro versions of GRUB to decide if the EFI
binary may be executed.
As the Linux kernel neither has RWX sections nor needs RWX pages for
relocation we should set the flag.

RISC-V: disallow gcc + rust builds
During the discussion before supporting rust on riscv, it was decided
not to support gcc yet, due to differences in extension handling
compared to llvm (only the version of libclang matching the c compiler
is supported). Recently Jason Montleon reported [1] that building with
gcc caused build issues, due to unsupported arguments being passed to
libclang. After some discussion between myself and Miguel, it is better
to disable gcc + rust builds to match the original intent, and
subsequently support it when an appropriate set of extensions can be
deduced from the version of libclang.

RISC-V: ACPI: fix early_ioremap to early_memremap
When SVPBMT is enabled, __acpi_map_table() will directly access the
data in DDR through the IO attribute, rather than through hardware
cache consistency, resulting in incorrect data in the obtained ACPI
table.
The log: ACPI: [ACPI:0x18] Invalid zero length.
We do not assume whether the bootloader flushes or not. We should
access in a cacheable way instead of maintaining cache consistency
by software.

riscv: dts: starfive: disable unused csi/camss nodes
Aurelien reported probe failures due to the csi node being enabled
without having a camera attached to it. A camera was in the initial
submissions, but was removed from the dts, as it had not actually been
present on the board, but was from an addon board used by the
developer of the relevant drivers. The non-camera pipeline nodes were
not disabled when this happened and the probe failures are problematic
for Debian. Disable them.

riscv, bpf: Make BPF_CMPXCHG fully ordered
According to the prototype formal BPF memory consistency model
discussed e.g. in [1] and following the ordering properties of
the C/in-kernel macro atomic_cmpxchg(), a BPF atomic operation
with the BPF_CMPXCHG modifier is fully ordered. However, the
current RISC-V JIT lowerings fail to meet such memory ordering
property. This is illustrated by the following litmus test:
BPF BPF__MP+success_cmpxchg+fence
{
0:r1=x; 0:r3=y; 0:r5=1;
1:r2=y; 1:r4=f; 1:r7=x;
}
P0 | P1 ;
*(u64 *)(r1 + 0) = 1 | r1 = *(u64 *)(r2 + 0) ;
r2 = cmpxchg_64 (r3 + 0, r4, r5) | r3 = atomic_fetch_add((u64 *)(r4 + 0), r5) ;
| r6 = *(u64 *)(r7 + 0) ;
exists (1:r1=1 /\ 1:r6=0)
whose "exists" clause is not satisfiable according to the BPF
memory model. Using the current RISC-V JIT lowerings, the test
can be mapped to the following RISC-V litmus test:
RISCV RISCV__MP+success_cmpxchg+fence
{
0:x1=x; 0:x3=y; 0:x5=1;
1:x2=y; 1:x4=f; 1:x7=x;
}
P0 | P1 ;
sd x5, 0(x1) | ld x1, 0(x2) ;
L00: | amoadd.d.aqrl x3, x5, 0(x4) ;
lr.d x2, 0(x3) | ld x6, 0(x7) ;
bne x2, x4, L01 | ;
sc.d x6, x5, 0(x3) | ;
bne x6, x4, L00 | ;
fence rw, rw | ;
L01: | ;
exists (1:x1=1 /\ 1:x6=0)
where the two stores in P0 can be reordered. Update the RISC-V
JIT lowerings/implementation of BPF_CMPXCHG to emit an SC with
RELEASE ("rl") annotation in order to meet the expected memory
ordering guarantees. The resulting RISC-V JIT lowerings of
BPF_CMPXCHG match the RISC-V lowerings of the C atomic_cmpxchg().

riscv, bpf: Fix possible infinite tailcall when CONFIG_CFI_CLANG is enabled
When CONFIG_CFI_CLANG is enabled, the number of prologue instructions
skipped by tailcall needs to include the kcfi instruction, otherwise the
TCC will be initialized every tailcall is called, which may result in
infinite tailcalls.

riscv: Fix kernel stack size when KASAN is enabled
We use Kconfig to select the kernel stack size, doubling the default
size if KASAN is enabled.
But that actually only works if KASAN is selected from the beginning,
meaning that if KASAN config is added later (for example using
menuconfig), CONFIG_THREAD_SIZE_ORDER won't be updated, keeping the
default size, which is not enough for KASAN as reported in [1].
So fix this by moving the logic to compute the right kernel stack into a
header.

Pull x86 kvm updates from Paolo Bonzini:
"x86:
- KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or
deleted.
This does not traditionally have particularly noticeable overhead,
but Intel's TDX will require the guest to re-accept private pages
if they are dropped from the secure EPT, which is a non starter.
Actually, the only reason why this is not already being done is a
bug which was never fully investigated and caused VM instability
with assigned GeForce GPUs, so allow userspace to opt into the new
behavior.
- Advertise AVX10.1 to userspace (effectively prep work for the
"real" AVX10 functionality that is on the horizon)
- Rework common MSR handling code to suppress errors on userspace
accesses to unsupported-but-advertised MSRs
This will allow removing (almost?) all of KVM's exemptions for
userspace access to MSRs that shouldn't exist based on the vCPU
model (the actual cleanup is non-trivial future work)
- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC)
splits the 64-bit value into the legacy ICR and ICR2 storage,
whereas Intel (APICv) stores the entire 64-bit value at the ICR
offset
- Fix a bug where KVM would fail to exit to userspace if one was
triggered by a fastpath exit handler
- Add fastpath handling of HLT VM-Exit to expedite re-entering the
guest when there's already a pending wake event at the time of the
exit
- Fix a WARN caused by RSM entering a nested guest from SMM with
invalid guest state, by forcing the vCPU out of guest mode prior to
signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the
nested guest)
- Overhaul the "unprotect and retry" logic to more precisely identify
cases where retrying is actually helpful, and to harden all retry
paths against putting the guest into an infinite retry loop
- Add support for yielding, e.g. to honor NEED_RESCHED, when zapping
rmaps in the shadow MMU
- Refactor pieces of the shadow MMU related to aging SPTEs in
prepartion for adding multi generation LRU support in KVM
- Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is
enabled, i.e. when the CPU has already flushed the RSB
- Trace the per-CPU host save area as a VMCB pointer to improve
readability and cleanup the retrieval of the SEV-ES host save area
- Remove unnecessary accounting of temporary nested VMCB related
allocations
- Set FINAL/PAGE in the page fault error code for EPT violations if
and only if the GVA is valid. If the GVA is NOT valid, there is no
guest-side page table walk and so stuffing paging related metadata
is nonsensical
- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit
instead of emulating posted interrupt delivery to L2
- Add a lockdep assertion to detect unsafe accesses of vmcs12
structures
- Harden eVMCS loading against an impossible NULL pointer deref
(really truly should be impossible)
- Minor SGX fix and a cleanup
- Misc cleanups
Generic:
- Register KVM's cpuhp and syscore callbacks when enabling
virtualization in hardware, as the sole purpose of said callbacks
is to disable and re-enable virtualization as needed
- Enable virtualization when KVM is loaded, not right before the
first VM is created
Together with the previous change, this simplifies a lot the logic
of the callbacks, because their very existence implies
virtualization is enabled
- Fix a bug that results in KVM prematurely exiting to userspace for
coalesced MMIO/PIO in many cases, clean up the related code, and
add a testcase
- Fix a bug in kvm_clear_guest() where it would trigger a buffer
overflow _if_ the gpa+len crosses a page boundary, which thankfully
is guaranteed to not happen in the current code base. Add WARNs in
more helpers that read/write guest memory to detect similar bugs
Selftests:
- Fix a goof that caused some Hyper-V tests to be skipped when run on
bare metal, i.e. NOT in a VM
- Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES
guest
- Explicitly include one-off assets in .gitignore. Past Sean was
completely wrong about not being able to detect missing .gitignore
entries
- Verify userspace single-stepping works when KVM happens to handle a
VM-Exit in its fastpath
- Misc cleanups"

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up
objtool warnings), teach objtool about 'noreturn' Rust symbols and
mimic '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we
should be objtool-warning-free, so enable it to run for all Rust
object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on
change.
- Split helpers file into several files in a folder, to avoid
conflicts in it. Eventually those files will be moved to the right
places with the new build system. In addition, remove the need to
manually export the symbols defined there, reusing existing
machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a
'ListArc' exists using an atomic), 'ListLinks' (the prev/next
pointers for an item in a linked list), 'List' (the linked list
itself), 'Iter' (an iterator over a 'List'), 'Cursor' (a cursor
into a 'List' that allows to remove elements), 'ListArcField' (a
field exclusively owned by a 'ListArc'), as well as support for
heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the
upcoming Rust Binder.
This includes 'RBTree' (the red-black tree itself), 'RBTreeNode' (a
node), 'RBTreeNodeReservation' (a memory reservation for a node),
'Iter' and 'IterMut' (immutable and mutable iterators), 'Cursor'
(bidirectional cursor that allows to remove elements), as well as
an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the
'InPlaceWrite' trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for
those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.

Pull i2c updates from Wolfram Sang:
"I2C core:
- finally remove the I2C_COMPAT symbol after 15 years of deprecation
- lock client addresses during initialization to prevent race
conditions between different kinds of instantiation
- use scoped foreach OF child loops
- testunit cleanups and documentation improvements, as well as two
new tests, one for repeated start and one for triggering SMBusAlert
interrupts
I2C host drivers:
- DesignWare and Renesas I2C driver updates.
The first has has undergone through a series of cleanups that have
been sent to the mailing list a year ago for the first time and
finally get merged in this pull request. They are many, from typos
(e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
functions to librarieas) and many others.
- all the DesignWare Kconfig options have been grouped under the
I2C_DESIGNWARE_CORE and this required some adaptation in many of
the kernel configuration files for different arm and mips boards
Cleanups:
- improve the exit path in the runtime resume function for the
Qualcomm Geni platform
- get rid of the unused "target_addr" parameter in the Intel LJCA
driver
- intialize the restart_flag in the MediaTek controller in one single
place
- constify a few global data structures in the virtio driver
- simplify the bus speed handling in the Renesas driver init function
making it more readable
- improved probe function of the Renesas R-Car driver
- switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
SET_RUNTIME_PM_OPS()
- iMX/MXC driver cleanups
- use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
and MPC drivers
Refactoring:
- Fix a potential out of boundary array access in the Nuvoton driver.
This is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The change
makes the driver more future proof and, at the same time, silences
code analyzers.
Improvements:
- several patches improving the runtime power management handling of
the Renesas I2C (riic) driver
- use a more descriptive adapter name in the Intel i801 driver to
show the presence of the IDF feature
- kill pending transactions when irq's can't complete their handling
in the Intel Denverton (ismt) driver, triggering a timeout
New Feature:
- support fast mode plus in the Renesas I2C (riic) driver
New support:
- Added support for:
- Renesas R9A08G045
- Rockchip RK3576
- KEBA I2C
- Theobroma Systems Mule Multiplexer.
- new i2c-keba.c driver
- new driver for The Mule i2c multiplexer
Core I2C framework:
- move runtime PM functions in order to allow them to be accessed
during device add
Devicetree:
- nVidia and Qualcomm binding improvements
- get rid of redundant "multi-master" property in the aspeed binding
- convert i2c-sprd binding to YAML

Merge branch 'kvm-redo-enable-virt' into HEAD
Register KVM's cpuhp and syscore callbacks when enabling virtualization in hardware, as the sole purpose of said callbacks is to disable and re-enable virtualization as needed. The primary motivation for this series is to simplify dealing with enabling virtualization for Intel's TDX, which needs to enable virtualization when kvm-intel.ko is loaded, i.e. long before the first VM is created. That said, this is a nice cleanup on its own. By registering the callbacks on-demand, the callbacks themselves don't need to check kvm_usage_count, because their very existence implies a non-zero count. Patch 1 (re)adds a dedicated lock for kvm_usage_count. This avoids a lock ordering issue between cpus_read_lock() and kvm_lock. The lock ordering issue still exist in very rare cases, and will be fixed for good by switching vm_list to an (S)RCU-protected list. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

RISC-V: Implement kgdb_roundup_cpus() to enable future NMI Roundup
Until now, the generic weak kgdb_roundup_cpus() has been used for kgdb on RISCV. A custom one allows to debug CPUs that are stuck with interrupts disabled with NMI support in the future. And using an IPI is better than the generic one since it avoids the potential situation described in the generic kgdb_call_nmi_hook(). As Andrew pointed out, once there is NMI support, we can easily extend this and the CPU backtrace support to use NMIs. After this patch, the kgdb test show that: # echo g > /proc/sysrq-trigger [2]kdb> btc btc: cpu status: Currently on cpu 2 Available cpus: 0-1(-), 2, 3(-) Stack traceback for pid 0 0xffffffff81c13a40 0 0 1 0 - 0xffffffff81c14510 swapper/0 CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.10.0-g3120273055b6-dirty #51 Hardware name: riscv-virtio,qemu (DT) Call Trace: [<ffffffff80006c48>] dump_backtrace+0x28/0x30 [<ffffffff80fceb38>] show_stack+0x38/0x44 [<ffffffff80fe6a04>] dump_stack_lvl+0x58/0x7a [<ffffffff80fe6a3e>] dump_stack+0x18/0x20 [<ffffffff801143fa>] kgdb_cpu_enter+0x682/0x6b2 [<ffffffff801144ca>] kgdb_nmicallback+0xa0/0xac [<ffffffff8000a392>] handle_IPI+0x9c/0x120 [<ffffffff800a2baa>] handle_percpu_devid_irq+0xa4/0x1e4 [<ffffffff8009cca8>] generic_handle_domain_irq+0x28/0x36 [<ffffffff800a9e5c>] ipi_mux_process+0xe8/0x110 [<ffffffff806e1e30>] imsic_handle_irq+0xf8/0x13a [<ffffffff8009cca8>] generic_handle_domain_irq+0x28/0x36 [<ffffffff806dff12>] riscv_intc_aia_irq+0x2e/0x40 [<ffffffff80fe6ab0>] handle_riscv_irq+0x54/0x86 [<ffffffff80ff2e4a>] call_on_irq_stack+0x32/0x40 Rebased on Ryo Takakura's "RISC-V: Enable IPI CPU Backtrace" patch.

Merge tag 'for-linus-non-x86' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"These are the non-x86 changes (mostly ARM, as is usually the case).
The generic and x86 changes will come later"
ARM:
- New Stage-2 page table dumper, reusing the main ptdump
infrastructure
- FP8 support
- Nested virtualization now supports the address translation
(FEAT_ATS1A) family of instructions
- Add selftest checks for a bunch of timer emulation corner cases
- Fix multiple cases where KVM/arm64 doesn't correctly handle the
guest trying to use a GICv3 that wasn't advertised
- Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little simpler
- Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster
- Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)
- When walking a page table to split block mappings, synchronize only
at the end the walk rather than on every store
- Fix boundary check when transfering memory using FFA
- Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind
LoongArch:
- Revert qspinlock to test-and-set simple lock on VM.
- Add Loongson Binary Translation extension support.
- Add PMU support for guest.
- Enable paravirt feature control from VMM.
- Implement function kvm_para_has_feature().
RISC-V:
- Fix sbiret init before forwarding to userspace
- Don't zero-out PMU snapshot area before freeing data
- Allow legacy PMU access from guest
- Fix to allow hpmcounter31 from the guest"
