tracing updates for v7.1:
- Fix printf format warning for bprintf
sunrpc uses a trace_printk() that triggers a printf warning during the
compile. Move the __printf() attribute around for when debugging is not
enabled the warning will go away.
- Remove redundant check for EVENT_FILE_FL_FREED in event_filter_write()
The FREED flag is checked in the call to event_file_file() and then
checked again right afterward, which is unneeded.
- Clean up event_file_file() and event_file_data() helpers
These helper functions played a different role in the past, but now with
eventfs, the READ_ONCE() isn't needed. Simplify the code a bit and also
add a warning to event_file_data() if the file or its data is not present.
- Remove updating file->private_data in tracing open
All access to the file private data is handled by the helper functions,
which do not use file->private_data. Stop updating it on open.
- Show ENUM names in function arguments via BTF in function tracing
When showing the function arguments when func-args option is set for
function tracing, if one of the arguments is found to be an enum, show the
name of the enum instead of its number.
- Add new trace_call__##name() API for tracepoints
Tracepoints are enabled via static_branch() blocks, where when not
enabled, there's only a nop that is in the code where the execution will
just skip over it. When tracing is enabled, the nop is converted to a
direct jump to the tracepoint code. Sometimes more calculations are
required to be performed to update the parameters of the tracepoint. In
this case, trace_##name##_enabled() is called which is a static_branch()
that gets enabled only when the tracepoint is enabled. This allows the
extra calculations to also be skipped by the nop:
if (trace_foo_enabled()) {
x = bar();
trace_foo(x);
}
Where the x=bar() is only performed when foo is enabled. The problem with
this approach is that there's now two static_branch() calls. One for
checking if the tracepoint is enabled, and then again to know if the
tracepoint should be called. The second one is redundant.
Introduce trace_call__foo() that will call the foo() tracepoint directly
without doing a static_branch():
if (trace_foo_enabled()) {
x = bar();
trace_call__foo();
}
- Update various locations to use the new trace_call__##name() API
- Move snapshot code out of trace.c
Cleaning up trace.c to not be a "dump all", move the snapshot code out of
it and into a new trace_snapshot.c file.
- Clean up some "%*.s" to "%*s"
- Allow boot kernel command line options to be called multiple times
Have options like:
ftrace_filter=foo ftrace_filter=bar ftrace_filter=zoo
Equal to:
ftrace_filter=foo,bar,zoo
- Fix ipi_raise event CPU field to be a CPU field
The ipi_raise target_cpus field is defined as a __bitmask(). There is now a
__cpumask() field definition. Update the field to use that.
- Have hist_field_name() use a snprintf() and not a series of strcat()
It's safer to use snprintf() that a series of strcat().
- Fix tracepoint regfunc balancing
A tracepoint can define a "reg" and "unreg" function that gets called
before the tracepoint is enabled, and after it is disabled respectively.
But on error, after the "reg" func is called and the tracepoint is not
enabled, the "unreg" function is not called to tear down what the "reg"
function performed.
- Fix output that shows what histograms are enabled
Event variables are displayed incorrectly in the histogram output.
Instead of "sched.sched_wakeup.$var", it is showing
"$sched.sched_wakeup.var" where the '$' is in the incorrect location.
- Some other simple cleanups.

Arm:
- Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis. This uses the new infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware, and which came through the tracing tree. - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM. - Finally add support for pKVM protected guests, where pages are unmapped from the host as they are faulted into the guest and can be shared back from the guest using pKVM hypercalls. Protected guests are created using a new machine type identifier. As the elusive guestmem has not yet delivered on its promises, anonymous memory is also supported. This is only a first step towards full isolation from the host; for example, the CPU register state and DMA accesses are not yet isolated. Because this does not really yet bring fully what it promises, it is hidden behind CONFIG_ARM_PKVM_GUEST + 'kvm-arm.mode=protected', and also triggers TAINT_USER when a VM is created. Caveat emptor. - Rework the dreaded user_mem_abort() function to make it more maintainable, reducing the amount of state being exposed to the various helpers and rendering a substantial amount of state immutable. - Expand the Stage-2 page table dumper to support NV shadow page tables on a per-VM basis. - Tidy up the pKVM PSCI proxy code to be slightly less hard to follow. - Fix both SPE and TRBE in non-VHE configurations so that they do not generate spurious, out of context table walks that ultimately lead to very bad HW lockups. - A small set of patches fixing the Stage-2 MMU freeing in error cases. - Tighten-up accepted SMC immediate value to be only #0 for host SMCCC calls. - The usual cleanups and other selftest churn. LoongArch: - Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel(). - Add DMSINTC irqchip in kernel support. RISC-V: - Fix steal time shared memory alignment checks - Fix vector context allocation leak - Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi() - Fix double-free of sdata in kvm_pmu_clear_snapshot_area() - Fix integer overflow in kvm_pmu_validate_counter_mask() - Fix shift-out-of-bounds in make_xfence_request() - Fix lost write protection on huge pages during dirty logging - Split huge pages during fault handling for dirty logging - Skip CSR restore if VCPU is reloaded on the same core - Implement kvm_arch_has_default_irqchip() for KVM selftests - Factored-out ISA checks into separate sources - Added hideleg to struct kvm_vcpu_config - Factored-out VCPU config into separate sources - Support configuration of per-VM HGATP mode from KVM user space s390: - Support for ESA (31-bit) guests inside nested hypervisors. - Remove restriction on memslot alignment, which is not needed anymore with the new gmap code. - Fix LPSW/E to update the bear (which of course is the breaking event address register). x86: - Shut up various UBSAN warnings on reading module parameter before they were initialized. - Don't zero-allocate page tables that are used for splitting hugepages in the TDP MMU, as KVM is guaranteed to set all SPTEs in the page table and thus write all bytes. - As an optimization, bail early when trying to unsync 4KiB mappings if the target gfn can just be mapped with a 2MiB hugepage. x86 generic: - Copy single-chunk MMIO write values into struct kvm_vcpu (more precisely struct kvm_mmio_fragment) to fix use-after-free stack bugs where KVM would dereference stack pointer after an exit to userspace. - Clean up and comment the emulated MMIO code to try to make it easier to maintain (not necessarily "easy", but "easier"). - Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of VMX and SVM enabling) as it is needed for trusted I/O. - Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions - Immediately fail the build if a required #define is missing in one of KVM's headers that is included multiple times. - Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected exception, mostly to prevent syzkaller from abusing the uAPI to trigger WARNs, but also because it can help prevent userspace from unintentionally crashing the VM. - Exempt SMM from CPUID faulting on Intel, as per the spec. - Misc hardening and cleanup changes. x86 (AMD): - Fix and optimize IRQ window inhibit handling for AVIC; make it per-vCPU so that KVM doesn't prematurely re-enable AVIC if multiple vCPUs have to-be-injected IRQs. - Clean up and optimize the OSVW handling, avoiding a bug in which KVM would overwrite state when enabling virtualization on multiple CPUs in parallel. This should not be a problem because OSVW should usually be the same for all CPUs. - Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a "too large" size based purely on user input. - Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION. - Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as doing so for an SNP guest will crash the host due to an RMP violation page fault. - Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are required to hold kvm->lock, and enforce it by lockdep. Fix various bugs where sev_guest() was not ensured to be stable for the whole duration of a function or ioctl. - Convert a pile of kvm->lock SEV code to guard(). - Play nicer with userspace that does not enable KVM_CAP_EXCEPTION_PAYLOAD, for which KVM needs to set CR2 and DR6 as a response to ioctls such as KVM_GET_VCPU_EVENTS (even if the payload would end up in EXITINFO2 rather than CR2, for example). Only set CR2 and DR6 when consumption of the payload is imminent, but on the other hand force delivery of the payload in all paths where userspace retrieves CR2 or DR6. - Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT instead of vmcb02->save.cr2. The value is out of sync after a save/restore or after a #PF is injected into L2. - Fix a class of nSVM bugs where some fields written by the CPU are not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not up-to-date when saved by KVM_GET_NESTED_STATE. - Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after save+restore. - Add a variety of missing nSVM consistency checks. - Fix several bugs where KVM failed to correctly update VMCB fields on nested #VMEXIT. - Fix several bugs where KVM failed to correctly synthesize #UD or #GP for SVM-related instructions. - Add support for save+restore of virtualized LBRs (on SVM). - Refactor various helpers and macros to improve clarity and (hopefully) make the code easier to maintain. - Aggressively sanitize fields when copying from vmcb12, to guard against unintentionally allowing L1 to utilize yet-to-be-defined features. - Fix several bugs where KVM botched rAX legality checks when emulating SVM instructions.

This uses the new infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware, and which came through the tracing tree - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM - Finally add support for pKVM protected guests, where pages are unmapped from the host as they are faulted into the guest and can be shared back from the guest using pKVM hypercalls. Protected guests are created using a new machine type identifier. As the elusive guestmem has not yet delivered on its promises, anonymous memory is also supported This is only a first step towards full isolation from the host; for example, the CPU register state and DMA accesses are not yet isolated.

parisc: led: fix reference leak on failed device registration
When platform_device_register() fails in startup_leds(), the embedded
struct device in platform_leds has already been initialized by
device_initialize(), but the failure path only reports the error and
does not drop the device reference for the current platform device:
startup_leds()
-> platform_device_register(&platform_leds)
-> device_initialize(&platform_leds.dev)
-> setup_pdev_dma_masks(&platform_leds)
-> platform_device_add(&platform_leds)
This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() after reporting the error.
The issue was identified by a static analysis tool I developed and
confirmed by manual review.

On the 32-bit parisc architecture, we always used the -ffunction-sections compiler option to tell the compiler to put the functions into seperate text sections. This is necessary, otherwise "big" kernel modules like ext4 or ipv6 fail to load because some branches won't be able to reach their stubs. Commit |

soc: drivers for 7.1
The driver updates again are all over the place with many minor fixes
going into platform specific code. The most notable changes are:
- Support for Microchip pic64gx system controllers
- Work on cleaning up devicetree bindings for SoC drivers, and
converting them into the new format
- Lots of smaller changes for Qualcomm SoC drivers, including support
for a number of newly supported chips
- reset controller API cleanups and a new driver for Cix Sky1
- Reworks of the Tegra PMC and CBB drivers, along with a change
to how individual Tegra SoCs get selected in Kconfig and
BPMP firmware driver updates including a refresh of the ABI
header to match the version used by firmware
- STM32 updates to the firewall bus driver and support for
the debug bus through OP-TEE

soc: dt changes for 7.1
A number of SoC platforms are adding modernized variants of their
already supported chips time, with a total of 12 new SoCs,
and two older SoC getting removed:
- Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores
- Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but
largely identical.
- Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and IOT
(QC7790S/M) workloads
- Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53 cores
- Qualcomm apq8084 and ipq806x had only rudimentary support but no
actual products using them, so they are now gone.
- Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using
the Samsung SoC platform but now with Cortex-A55 cores
- ARM Zena is a virtual platform in FVP using Cortex-A720AE cores, with
additional versions planned to be merged in the future.
- ARM corstone-1000-a320 is a reference platform for IOT, using low-end
Cortex-A320 cores
- Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x
series of networking SoCs
- Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU cores
- Rockchip RV1103B is the low-end 32-bit single-core vision processor
- Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using
Cortex-A55 cores, similar to the G3E and G3S variants we already
supported.
- NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a
significant upgrade from the older S32V and S32G series
These all come with at least one reference board or an initial product
using these, in total there are 67 newly added boards. The ones for
already supported SoCs are:
- Two more Aspeed BMC based boards
- Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs
- One Set-top-box based on Allwinner H6
- 22 additional industrial/embedded boards using 64-bit NXP i.MX8M
or i.MX9 SoCs
- 20 Qualcomm SoC based machines across all possible markets:
workstation, gaming, laptop, phone, networking, reference, ...
- Three more Rockchips rk35xx based boards
- Four variants of the Toradex Verdin using TI AM62
Other notable bits are:
- A cleanup for the 32-bit Tegra paz00 board moved the last
board specific code on Tegra into equivalent dts syntax.
- There continues to be a significant number of fixes for static
checking of dtc syntax, but it feels like this is slowing down,
hopefully getting into a state where most known issues are
addressed
- Additional hardware support for many existing boards across SoC
families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips,
STM32, Mediatek, Tegra, TI and Microchip

Reviewed rate: 76%
- The 2 patch series "pid: make sub-init creation retryable" from Oleg
Nesterov increases the robustness of our creation of init in a new

from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
selftest.

Andy Shevchenko does as advertised.
- The 3 patch series "hung_task: Provide runtime reset interface for
hung task detector" from Aaron Tomlin gives administrators the ability
to zero out /proc/sys/kernel/hung_task_detect_count.
- The 2 patch series "tools/getdelays: use the static UAPI headers from

in-kernel UAPI headers rather than the system-provided ones.
- The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
from Mayank Rungta provides several cleanups and fixups to the
hardlockup detector code and its documentation.
- The 2 patch series "lib/bch: fix undefined behavior from signed

in the bch code.
- The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
from Junrui Luo does what is claims.
- The 27 patch series "cleanup the RAID5 XOR library" from Christoph
Hellwig is a quite far-reaching cleanup to this code. I can't do better
than to quote Christoph:
The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography and
not using the crypto API, with the generic implementations sitting in
include/asm-generic and the arch implementations sitting in an asm/
header in theory. The latter doesn't work for many cases, so
architectures often build the code directly into the core kernel, or
create another module for the architecture code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric Biggers
has done for the CRC and crypto libraries later. After that it
changes to better calling conventions that allow for smarter
architecture implementations (although none is contained here yet),
and uses static_call to avoid indirection function call overhead.
- The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
workarounds" from Kuan-Wei Chiu cleans up this library code by removing
a hacky thing which was added for UBIFS, which UBIFS doesn't actually
need.
- The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
for the now-fixed bugs and fixes a leak in the test itself.
- The 3 patch series "kdump: Enable LUKS-encrypted dump target support
in ARM64 and PowerPC" from Coiby Xu eenables support of the
LUKS-encrypted device dump target on arm64 and powerpc.
- The 4 patch series "ocfs2: consolidate extent list validation into
block read callbacks" from Joseph Qi addresses ocfs2's validation of
extent list fields - cleanup, simplification, robustness. (Kernel test
robot loves mounting corrupted fs images!)

libbpf: Prevent double close and leak of btf objects
Sashiko found possible double close of btf object fd [1],
which happens when strdup in load_module_btfs fails at which
point the obj->btf_module_cnt is already incremented.
The error path close btf fd and so does later cleanup code in
bpf_object_post_load_cleanup function.
Also libbpf_ensure_mem failure leaves btf object not assigned
and it's leaked.
Replacing the err_out label with break to make the error path
less confusing as suggested by Alan.
Incrementing obj->btf_module_cnt only if there's no failure
and releasing btf object in error path.

Merge branch 'bpf-allow-utf-8-literals-in-bpf_bprintf_prepare'
Yihan Ding says: ==================== bpf: allow UTF-8 literals in bpf_bprintf_prepare() bpf_bprintf_prepare() currently rejects any non-ASCII byte in format strings, so helpers such as bpf_trace_printk() fail to emit UTF-8 literal text even when those bytes are not part of a format specifier. Keep plain text permissive while continuing to parse '%' sequences as ASCII-only. Patch 1 updates snprintf_negative() at the same time so the selftests stay consistent during bisection. Patch 2 then extends trace_printk coverage for both the valid UTF-8 literal case and the invalid non-ASCII-after-'%' case. Changes in v3: - drop Suggested-by trailers and move review credit into this changelog - update test_snprintf_negative() in patch 1/2 so plain non-ASCII text is accepted while non-ASCII after '%' is still rejected, keeping ./test_progs -t snprintf aligned with the new behavior. - clarify the trace_printk negative case with an explicit invalid format string and comment - address Paul Chaignon's review feedback and keep the negative coverage requested earlier by Alan Maguire Changes in v2: - split the core change and selftest updates into two patches - drop unnecessary isspace()/ispunct() casts - add comments to clarify plain-text vs format-specifier handling - add a negative selftest for non-ASCII bytes inside '%' sequences Testing: - Reproduced on x86_64 without the core fix: ASCII trace output works, while UTF-8 literal text in bpf_trace_printk() is rejected and produces no trace output - Verified with tools/testing/selftests/bpf: ./test_progs -t trace_printk - Verified with tools/testing/selftests/bpf: ./test_progs -t snprintf ==================== Link: https://patch.msgid.link/20260416120142.1420646-1-dingyihan@uniontech.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

selftests/bpf: cover UTF-8 trace_printk output
Extend trace_printk coverage to verify that UTF-8 literal text is emitted successfully and that '%' parsing still rejects non-ASCII bytes once format parsing starts. Use an explicitly invalid format string for the negative case so the ASCII-only parser expectation is visible from the test code itself.

bpf: allow UTF-8 literals in bpf_bprintf_prepare()
bpf_bprintf_prepare() only needs ASCII parsing for conversion
specifiers. Plain text can safely carry bytes >= 0x80, so allow
UTF-8 literals outside '%' sequences while keeping ASCII control
bytes rejected and format specifiers ASCII-only.
This keeps existing parsing rules for format directives unchanged,
while allowing helpers such as bpf_trace_printk() to emit UTF-8
literal text.
Update test_snprintf_negative() in the same commit so selftests keep
matching the new plain-text vs format-specifier split during bisection.

Merge branch 'bpf-fix-null-deref-when-storing-scalar-into-kptr-slot'
Mykyta Yatsenko says: ==================== bpf: Fix NULL deref when storing scalar into kptr slot map_kptr_match_type() accesses reg->btf before confirming the register is PTR_TO_BTF_ID. A scalar store into a kptr slot has no btf, causing a NULL pointer dereference. Guard base_type() first.

VFIO updates for v7.1-rc1
- Update QAT vfio-pci variant driver for Gen 5, 420xx devices.
(Vijay Sundar Selvamani, Suman Kumar Chakraborty, Giovanni Cabiddu)
- Fix vfio selftest MMIO DMA mapping selftest. (Alex Mastro)
- Conversions to const struct class in support of class_create()
deprecation. (Jori Koolstra)
- Improve selftest compiler compatibility by avoiding initializer
on variable-length array. (Manish Honap)
- Define new uAPI for drivers supporting migration to advise user-
space of new initial data for reducing target startup latency.
Implemented for mlx5 vfio-pci variant driver. (Yishai Hadas)
- Enable vfio selftests on aarch64, not just cross-compiles reporting
arm64. (Ted Logan)
- Update vfio selftest driver support to include additional DSA
devices. (Yi Lai)
- Unconditionally include debugfs root pointer in vfio device struct,
avoiding a build failure seen in hisi_acc variant driver without
debugfs otherwise. (Arnd Bergmann)
- Add support for the s390 ISM (Internal Shared Memory) device via
a new variant driver. The device is unique in the size of its BAR
space (256TiB) and lack of mmap support. (Julian Ruess)
- Enforce that vfio-pci drivers implement a name in their ops
structure for use in sequestering SR-IOV VFs. (Alex Williamson)
- Prune leftover group notifier code. (Paolo Bonzini)
- Fix Xe vfio-pci variant driver to avoid migration support as a
dependency in the reset path and missing release call.
