Merge tag 'rproc-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull remoteproc updates from Bjorn Andersson: - Add i.MX94 support to the i.MX remoteproc driver, covering the Cortex-M7 and Cortex-M33 Sync cores. This also fixes programming of non-zero System Manager CPU/LMM reset vectors. - Move the remoteproc resource table definitions to a separate header, so they can be used by clients that do not otherwise depend on remoteproc. Switch the firmware resource handling over to the common iterator. - Update the Xilinx R5F remoteproc driver to check the remote core state before attaching, drop a binding header dependency, and add firmware-name based auto boot support. - Add Qualcomm Hawi ADSP/CDSP bindings, together with Shikra RPM bindings and CDSP, LPAICP, and MPSS PAS support. Fix a Qualcomm minidump leak, clean up PAS and WCSS reset handling, and make the user-visible Qualcomm naming consistent. - Remove a duplicate STM32_RPROC Kconfig dependency and make i.MX remoteproc instances use the device node name so multiple processors can be distinguished in sysfs. * tag 'rproc-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: remoteproc: qcom: pas: Drop start/stop completion from struct qcom_pas remoteproc: qcom: pas: Add Shikra remoteproc support dt-bindings: remoteproc: qcom,shikra-pas: Document Shikra PAS remoteprocs dt-bindings: remoteproc: Add Shikra RPM processor compatible remoteproc: qcom: Unify user-visible "Qualcomm" name remoteproc: qcom: Fix leak when custom dump_segments addition fails remoteproc: qcom_q6v5_wcss: drop redundant wcss_q6_bcr_reset dt-bindings: remoteproc: qcom,sm8550-pas: Add Hawi CDSP compatible dt-bindings: remoteproc: qcom,sm8550-pas: Add Hawi ADSP compatible remoteproc: xlnx: Enable auto boot feature dt-bindings: remoteproc: xlnx: Add firmware-name property remoteproc: xlnx: Remove binding header dependency remoteproc: imx_rproc: Use device node name as processor name remoteproc: use rsc_table_for_each_entry() in rproc_handle_resources() remoteproc: Move resource table data structure to its own header remoteproc: xlnx: Check remote core state remoteproc: imx_rproc: Add support for i.MX94 remoteproc: imx_rproc: Program non-zero SM CPU/LMM reset vector dt-bindings: remoteproc: imx-rproc: Support i.MX94 remoteproc: Dead code cleanup in Kconfig for STM32_RPROC |

Merge tag 'integrity-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull IMA updates from Mimi Zohar: - Introduce IMA and EVM post-quantum ML-DSA signature support ML-DSA signature support for IMA and EVM is limited to sigv3 signatures, which calculates and verifies a hash of a compact structure containing the file data/metadata hash, hash type, and hash algorithm. IMA and EVM still calculate the file data/metadata hashes respectively. - Introduce support for removing IMA measurement list records stored in kernel memory The IMA measurement list can grow large depending on policy, but removing records breaks remote attestation, unless they are safely preserved and made available for attestation requests. Until environments are prepared to preserve the measurement records, a new CONFIG_IMA_STAGING Kconfig option is introduced to guard against deletion. Several approaches for removing measurement list records were evaluated but rejected due to filesystem constraints, the introduction of a new critical data record, and locking concerns. Two methods are being upstreamed: staged deletion with confirmation, and staged deletion of N records without confirmation. Both methods minimize the period during which new measurements are blocked from being appended to the measurement list by staging the measurement list. A comparison of the two methods is included in the documentation. - Some code cleanup, and a couple of bug fixes * tag 'integrity-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: doc: security: Add documentation of exporting and deleting IMA measurements ima: Support staging and deleting N measurements records ima: Add support for flushing the hash table when staging measurements ima: Add support for staging measurements with prompt ima: Introduce ima_dump_measurement() ima: Use snprintf() in create_securityfs_measurement_lists ima: Mediate open/release method of the measurements list ima: Introduce _ima_measurements_start() and _ima_measurements_next() ima: Introduce per binary measurements list type binary_runtime_size value ima: Introduce per binary measurements list type ima_num_records counter ima: Replace static htable queue with dynamically allocated array ima: Remove ima_h_table structure evm: terminate and bound the evm_xattrs read buffer integrity: Add support for sigv3 verification using ML-DSA keys integrity: Refactor asymmetric_verify for reusability integrity: Check that algo parameter is within valid range integrity: Check for NULL returned by asymmetric_key_public_key ima: return error early if file xattr cannot be changed ima: Fix sigv3 signature handling for EVM_IMA_XATTR_DIGSIG |

Merge tag 'mm-stable-2026-06-18-09-26' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
- "selftests/mm: clean up build output and verbosity" (Li Wang)
Remove some noise from the MM selftests build
- "mm: Free contiguous order-0 pages efficiently" (Ryan Roberts)
Speed up the freeing of a batch of 0-order pages by first scanning
them for coalescing opportunities. This is applicable to vfree() and
to the releasing of frozen pages
- "mm/damon: introduce DAMOS failed region quota charge ratio"
(SeongJae Park)
Address a DAMOS usability issue: The DAMOS quota often exhausts
prematurely because it charges for all memory attempted, causing slow
and inconsistent performance when actions fail on unreclaimable
memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing

- "mm/damon/reclaim,lru_sort: monitor all system rams by default"
(SeongJae Park)
Simplify deployment on diverse hardware like NUMA systems by updating

- "mm/filemap: tighten mmap_miss hit accounting" (fujunjie)
Fix a flaw where the mmap_miss counter over-credited page cache hits
during fault-arounds and page-fault retries. This results in
significant reduction of redundant synchronous mmap readahead I/O,
drastically cutting down execution time and gigabytes read for sparse
random or strided memory access workloads

kmemleak output
- "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)" (David
Hildenbrand)
Reduce our use of CONFIG_HAVE_BOOTMEM_INFO_NODE, with a view to
removing it entirely in a later series
- "mm/damon: validate min_region_size to be power of 2" (Liew Rui Yan)
Prevent users from passing a non-power-of-2 value of `addr_unit', as

Pull kvm updates from Paolo Bonzini:
"arm64:
This is a bit of an odd merge window on the KVM/arm64 front. There
is absolutely no new feature in the pull request. It is purely
fixes, because it is simply becoming too hard to review new stuff
when so many AI-fuelled fixes hit the list.
- Significant cleanup of the vgic-v5 PPI support which was merged in
7.1. This makes the code more maintainable, and squashes a couple
of bugs in the meantime
- Set of fixes for the handling of the MMU in an NV context,
particularly VNCR-triggered faults. S1POE support is fixed as well
- Large set of pKVM fixes, mostly addressing recurring issues around
hypervisor tracking of donated pages in obscure cases where the
donation could fail and leave things in a bizarre state
- Fixes for the so-called "lazy vgic init", which resulted in
sleeping operations in non-preemptible sections. This turned out to
be far more invasive than initially expected..
- Reduce the overhead of L1/L2 context switch by not touching the FP
registers
- Fix the way non-implemented page sizes are dealt with when a guest
insist on using them for S2 translation
- The usual set of low-impact fixes and cleanups all over the map
Loongarch:
- On a request for lazy FPU load, load all FPU state that the VM
supports instead of enabling only the part (FPU, LSX or LASX) that
caused the FPU load request
- Some enhancements about interrupt injection
- Some bug fixes and other small changes
RISC-V:
- Batch G-stage TLB flushes for GPA range based page table updates
- Convert HGEI line management to fully per-HART
- Fix missing CSR dirty marking when FWFT state updated via ONE_REG
- Fix stale FWFT feature exposure to Guest/VM
- Speed up dirty logging write faults using MMU rwlock and atomic PTE
updates using cmpxchg() for permission-only changes
- Use flexible array for APLIC IRQ state
- Use kvm_slot_dirty_track_enabled() for logging enable check on a
memslot
- Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
- Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
- Use endian-specific __lelong for NACL shared memory
S390:
- KVM_PRE_FAULT_MEMORY support
- Support for 2G hugepages
- Support for the ASTFLEIE 2 facility
- Support for fast inject using kvm_arch_set_irq_inatomic
- Fix potential leak of uninitialized bytes
- A few more misc gmap fixes
x86:
- Generic support for the more granular permissions allowed by EPT,
namely "read" (which was previously usurping the U bit) and
separate execution bits for kernel and userspace
- Do not assume that all page tables start with U=1/W=1/NX=0 at the
root, as AMD GMET needs to have U=0 at the root
- Introduce common assembly macros for use within Intel and AMD
vendor-specific vmentry code. This touches the SPEC_CTRL handling,
which is now entirely done in assembly for Intel (by reusing the
AMD code that already existed), and register save/restore which
uses some macro magic to compute the offsets in the struct. Both of
these are preparatory changes for upcoming APX support
- Clean up KVM's register tracking and storage, primarily to prepare
for APX support, which expands the maximum number of GPRs from 16
to 32
- Keep a single copy of the PDPTRs rather than two, since
architecturally there is just one
- Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor
code gets a chance to handle things like reaping the PML buffer
- Update KVM's view of PV async enabling if and only if the MSR write
fully succeeds
- Fix a variety of issues where the emulator doesn't honor
guest-debug state, and clean up related code along the way
- Synthesize EPT Violation and #NPF "error code" bits when injecting
faults into L1 that didn't originate in hardware (in which case the
VMCS/VMCB doesn't hold relevant information)
- Add support for virtualizing (well, emulating) AMD's flavor of
CPL>0 CPUID faulting
- Clean up the GPR APIs so that KVM's use of "raw" is consistent, and
fix a variety of minor bugs along the way
- Fix an OOB memory access due to not checking the VP ID when
handling a Hyper-V PV TLB flush for L2
- Fix a bug in the mediated PMU's handling of fixed counters that
allowed the guest to bypass the PMU event filter
- Allow userspace to return EAGAIN when handling SNP and TDX
hypercalls, so the KVM can forward a "retry" status code to the
guest, and reserve all unused error codes for future usage
- Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific
logic as possible into the TDX code, and to funnel (almost) all
S-EPT updates into a single chokepoint. The motivation is largely
to prepare for upcoming Dynamic PAMT support, but the cleanups are
nice to have on their own
- Plug a hole in shadow page table handling, where KVM fails to
recursively zap nested EPT/NPT shadow page tables when the nested
hypervisor tears down its own EPT/NPT page tables from the bottom
up
x86 (Intel):
- Support for nested MBEC (Mode-Based Execute Control), see above in
the generic section; also run with MBEC enabled even for non-nested
mode
- Use the kernel's "enum pg_level" in the TDX APIs instead of the
TDX-Module's level definitions (which are 0-based)
- Rework the TDX memory APIs to not require/assume that guest memory
is backed by "struct page" (in prepartion for guest_memfd hugepage
support)
- Fix a largely benign bug where KVM TDX would incorrectly state it
could emulate several x2APIC MSRs
- Use the "safe" WRMSR API when proxying LBR MSR writes as the
to-be-written value is guest controlled and completely unvalidated
x86 (AMD):
- Support for nested GMET (Guest Mode Execution Trap), see above in
the generic section; also run with GMET enabled even for non-nested
mode
- Fixes and minor cleanups to GHCB handling, on top of the earlier
work already merged into 7.1-rc
- Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
fastpath handlers
- Add support for virtualizing gPAT (KVM previously just used L1's
PAT when running L2)
- Fix goofs where KVM mishandles side effects (e.g. single-step and
PMC updates) when emulating VMRUN
- Fix a variety of bugs in AVIC's handling of x2APIC MSR
interception, most notably where KVM didn't disable interception of
IRR, ISR, and TMR regs
- Add support for virtualizing Host-Only/Guest-Only bits in the
mediated PMU
- Don't advertise support for unusable VM types, and account for VM
types that are disabled by firmware, e.g. to mitigate security
vulnerabilities
- Rewrite the SEV {en,de}crypt debug ioctls as they were riddle with
bugs and unnecessarily complicated, and add comprehensive tests
- Clean up and deduplicate the SEV page pinning code
- Fix minor goofs related to writing back CPUID information after
firmware rejects a CPUID page for an SNP vCPU
Generic:
- Rename invalidate_begin() to invalidate_start() throughout KVM to
follow the kernel's nomenclature, e.g. for mmu_notifiers
- Use guard() to cleanup up various KVM+VFIO flows
- Minor cleanups
guest_memfd:
- Return -EEXIST instead of -EINVAL if userspace attempts to bind a
gmem range to multiple memslots, and fix the test that was supposed
to ensure KVM returns -EEXIST
- Treat memslot binding offsets and sizes as unsigned values to fix a
bug where KVM interprets a large "offset + size" as a negative
value and allows a nonsensical offset
- Use the inode number instead of the page offset for the NUMA
interleaving index to fix a bug where the effective index would
jump by two for consecutive pages (the caller also adds in the page
offset)
Selftests:
- Randomize the dirty log test's delay when reaping the bitmap on the
first pass, as always waiting only 1ms hid a KVM RISC-V bug as the
test reaped the bitmap before KVM could build up enough state to
hit the bug
- A pile of one-off fixes and cleanups"

Merge tag 'trace-ring-buffer-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt - Do not invalidate entire buffer for invalid sub-buffers For the persistent ring buffer, if one sub-buffer is found to be invalid, it invalidates the entire per CPU ring buffer. This can lose a lot of valuable data if there's some corruption with the writes to the buffer not syncing properly on a hard crash. Instead, if a sub-buffer is found to be invalid, simply zero it out and mark it for "missed events". When the persistent ring buffer is read and a sub-buffer that was cleared due to being invalid on boot up is discovered, the output will show "[LOST EVENTS]" to let the user know that events were missing at that location. Displaying the events from valid buffers can still be useful. - Add a test to be able to test corrupted sub-buffers If a persistent ring buffer is created as "ptraingtest" and the new config that adds the test is enabled, when a panic happens, the kernel will randomly corrupt one of the per CPU ring buffers. On boot up, the sub-buffers with the corruption should be cleared and flagged. When reading this buffer, the missed events should should [LOST EVENTS]. - Add commit number in the sub-buffer meta debug info The commit is used to know the content of a meta page. Add it to the buffer_meta file that is shown for each per CPU buffer. - Clean up the persistent ring buffer validation code Add some helper functions and make variable names more consistent. * tag 'trace-ring-buffer-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Better comment the use of RB_MISSED_EVENTS ring-buffer: Show persistent buffer dropped events in trace_pipe file ring-buffer: Show persistent buffer dropped events in trace file ring-buffer: Have dropped subbuffers be persistent across reboots ring-buffer: Cleanup buffer_data_page related code ring-buffer: Cleanup persistent ring buffer validation ring-buffer: Show commit numbers in buffer_meta file ring-buffer: Add persistent ring buffer invalid-page inject test ring-buffer: Skip invalid sub-buffers when rewinding persistent ring buffer ring-buffer: Skip invalid sub-buffers when validating persistent ring buffer |

Pull tracing updates from Steven Rostedt: - Remove a redundant IS_ERR() check trace_pipe_open() already checks for IS_ERR() and does it again in the return path. Remove the return check. - Export seq_buf_putmem_hex() to allow kunit tests against them To add Kunit tests on seq_buf_putmem_hex(), it needs to be exported. - Replace strcat() and strcpy() with seq_buf() logic The code for synthetic events uses a series of strcat() and strcpy() which can be error prone. Replace them with seq_buf() logic that does all the necessary bound checking. - Add a lockdep rcu_is_watching() to trace_##event##_enabled() call The trace_##event##_enabled() is a static branch that is true if the "event" is enabled. But this can hide bugs if this logic is in a location where RCU is disabled and not "watching". It would only trigger if lockdep is enabled and the event is enabled. Add a "rcu_is_watching()" warning if lockdep is enabled in that helper function to trigger regardless if the event is enabled or not. - Remove the local variable in the trace_printk() macro For name space integrity, remove the _______STR variable in the trace_printk() macro for using the sizeof() macro directly. - Use guard()s for the trace_recursion_record.c file - Fix typo in a comment of eventfs_callback() kerneldoc - Use trace_call__##event() in events within trace_##event##_enabled() A couple of events are called within an if block guarded by trace_##event##_enabled(). That is a static key that is only enabled when the event is enabled. The trace_call_##event() calls the tracepoint code directly without adding a redundant static key for that check. - Allow perf to read synthetic events Currently, perf does not have the ability to enable a synthetic event. If it does, it will either cause a kernel warning or error with "No such device". Synthetic events are not much different than kprobes and perf can handle fine with a few modifications. - Replace printk(KERN_WARNING ...) with pr_warn() - Replace krealloc() on an array with krealloc_array() - Fix README file path name for synthetic events - Change tracing_map tracing_map_array to use a flexible array Instead of allocating a separate pointer to hold the pages field of tracing_map_array, allocate the pages field as a flexible array when allocating the structure. - Fold trace_iterator_increment() into trace_find_next_entry_inc() The function trace_iterator_increment() was only used by trace_find_next_entry_inc(). It's not big enough to be a helper function for one user. Fold it into its caller. - Make field_var_str field a flexible array of hist_elt_data Instead of allocating a separate pointer for the field_var_str array of the hist_elt_data structure, allocate it as a flexible array when allocating the structure. - Disable KCOV for trace_irqsoff.c Like trace_preemptirq.c, trace_irqsoff.c has code that will crash when KCOV is enabled on ARM. The irqsoff tracing can be called on ARM because the irqsoff tracing code can be run from early interrupt code and produce coverage unrelated to syscall inputs. - Fix warning in __unregister_ftrace_function() called by perf Perf calls unregister_ftrace_function() without checking if its ftrace_ops has already been unregistered. There's an error path where on clean up it will unregister the ftrace_ops even if it wasn't registered and causes a warning. * tag 'trace-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: perf/ftrace: Fix WARNING in __unregister_ftrace_function tracing: Disable KCOV instrumentation for trace_irqsoff.o tracing: Turn hist_elt_data field_var_str into a flexible array tracing: Move trace_iterator_increment() into trace_find_next_entry_inc() tracing: Simplify pages allocation for tracing_map logic tracing: Fix README path for synthetic_events tracing: Use krealloc_array() for trace option array growth tracing/branch: Use pr_warn() instead of printk(KERN_WARNING) tracing: Allow perf to read synthetic events HID: Use trace_call__##name() at guarded tracepoint call sites cpufreq: amd-pstate: Use trace_call__##name() at guarded tracepoint call site tracefs: Fix typo in a comment of eventfs_callback() kerneldoc tracing: Switch trace_recursion_record.c code over to use guard() tracing: Remove local variable for argument detection from trace_printk() tracepoint: Add lockdep rcu_is_watching() check to trace_##name##_enabled() tracing: Bound synthetic-field strings with seq_buf seq_buf: Export seq_buf_putmem_hex() and add KUnit tests tracing: Remove redundant IS_ERR() check in trace_pipe_open() |

string: Remove strncpy() from the kernel
strncpy() has been a persistent source of bugs due to its ambiguous intended usage and frequently counter-intuitive semantics: it may not NUL-terminate the destination, and it unconditionally zero-pads to the full length, which isn't always needed. All former callers have been migrated[1] to: - strscpy() for NUL-terminated destinations - strscpy_pad() for NUL-terminated destinations needing zero-padding - strtomem_pad() for non-NUL-terminated fixed-width fields - memcpy_and_pad() for bounded copies with explicit padding - memcpy() for known-length copies Remove the generic implementation, its declaration, the FORTIFY_SOURCE wrapper, and associated tests.

alpha: Remove arch-specific strncpy() implementation
strncpy() has no remaining callers in the kernel[1]. Remove the alpha-specific assembly implementation and __HAVE_ARCH_STRNCPY define, falling back to the generic version in lib/string.c. The __stxncpy helper (stxncpy.S/ev6-stxncpy.S) is retained as it is still used by strncat. Link: https://github.com/KSPP/linux/issues/90 [1] Signed-off-by: Kees Cook <kees@kernel.org> |

Merge tag 'nfsd-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever: "Jeff Layton wired up netlink upcalls for the auth.unix.ip and auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches in NFSD. The new kernel-user API is more extensible and lays the groundwork for retiring the old pipe interface. The default NFS r/w block size rises to 4MB on hosts with at least 16GB of RAM, reducing per-RPC overhead on fast networks. Smaller machines keep their previously computed default, and the value remains tunable through /proc/fs/nfsd/max_block_size. Chuck Lever converted the server's RPCSEC GSS Kerberos code to the kernel's shared crypto/krb5 library. The conversion retires and removes SunRPC's bespoke implementation of Kerberos v5, but keeps RPCSEC GSS-API. Continuing the xdrgen migration that converted the NLMv4 server XDR layer in v7.1, Chuck Lever converted the NLM version 3 server-side XDR layer from hand-written C to xdrgen-generated code. As with the NLMv4 conversion in v7.1, the goals are improved memory safety, lower maintenance burden, and groundwork for generation of Rust code for this layer instead of C. Chuck Lever fixed an issue where lingering NFSv4 state pins a mounted file system after it is unexported. A new netlink-based mechanism can now release NLM locks and NFSv4 state by client address, by filesystem, and by export. Now an administrator can quiesce an export cleanly before unmounting it. The remaining patches are bug fixes, clean-ups, and minor optimizations, including a batch of memory-leak and use-after-free fixes in the ACL, lockd, and TLS handshake paths, many of them reported by Chris Mason.

Pull m68knommu updates from Greg Ungerer: - an update and config refresh for the stmark board - fixes and preparatory work for supporting the DAC hardware block of the m5441x ColdFire SoC - forced configuration fix for legacy gpiolib when enabling the mcfqspi driver - new defconfigs for the M5329EVB, M54418EVB and NETtel boards to give better build test coverage For ColdFire parts - cleanup to register access code in the core init and setup code for ColdFire SoC be consistent, instead of a varied use of __raw_readX/__raw_write and straight readX/writeX. This is working towards fixing the non-standard endianess of the non-MMU m68k readX/writeX functions. * tag 'm68knommu-for-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (22 commits) m68k: stmark2: enable DACs outputs m68k: stmark2: add mcf5441x DAC platform devices m68k: stmark2: use ioport.h macros for resources m68k: mcf5441x: add CCR MISCCR2 bitfields m68k: mcf5441x: add CCM registers m68k: add DAC modules base addresses m68k: mcf5441x: add clock for DAC channel 1 m68k: mcf5441x: fix clocks numbering m68k: coldfire: use ColdFire specifc IO access in SoC code m68k: coldfire: use ColdFire specifc IO access in system code m68k: coldfire: rename timer register access defines m68k: coldfire: use ColdFire specifc IO access in timer code m68k: coldfire: use ColdFire specifc IO access in interrupt code m68k: coldfire: use ColdFire specific IO access in headers m68k: coldfire: create IO access functions for internal registers m68k: defconfig: update all ColdFire defconfigs m68k: defconfig: add config for SnapGear/NETtel board m68k: defconfig: add config for M54418EVB board m68k: defconfig: add config for M5329EVB board m68k: coldfire: select legacy gpiolib interface for mcfqspi ... |
