Patchsets in this merge:
- The 2 patch series "selftests/mm: clean up build output and verbosity"
from Li Wang removes some noise from the MM selftests build out.
- The 3 patch series "mm: Free contiguous order-0 pages efficiently"
from Ryan Roberts speeds 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.
- The 11 patch series "mm/damon: introduce DAMOS failed region quota
charge ratio" from SeongJae Park addresses 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
- The 8 patch series "selftests/cgroup: improve zswap tests robustness
and support large page sizes" from Li Wang fixes various spurious
failures and improves the overall robustness of the cgroup zswap
selftests.
- The 3 patch series "fix MAP_DROPPABLE not supported errno" from
Anthony Yznaga fixes an issue in the mlock selftests on arm32.
- The 2 patch series "mm: huge_memory: clean up defrag sysfs with
shared" from Breno Leitao does some maintenance work in the huge_memory
code.
- The 3 patch series "treewide: fixup gfp_t printks" from Brendan
Jackman uses the special vprintf() gfp_t conversion in various places.
- The 6 patch series "mm: Fix vmemmap optimization accounting and
initialization" from Muchun Song fixes several bugs in the vmemmap
optimization, mainly around incorrect page accounting and memmap
initialization in the DAX and memory hotplug paths. It also fixes
pageblock migratetype initialization and struct page initialization for
ZONE_DEVICE compound pages.
- The 4 patch series "mm/damon: repost non-hotfix reviewed patches in
damon/next tree" from is a sprinkle of unrelated minor bugfixes for
DAMON.
- The 3 patch series "mm: remove page_mapped()" from David Hildenbrand
remove this function from the tree, replacing it with folio_mapped().
- The 10 patch series "mm/damon: let DAMON be paused and resumed" from
SeongJae Park permits DAMON to be paused and resumed without losing its
current state.
- The 3 patch series "kasan: hw_tags: Disable tagging for stack and
page-tables" from Muhammad Usama Anjum simplifies and speeds up kasan by
removing its ineffective tagging of stacks and page tables.
- The 7 patch series "mm/damon/reclaim,lru_sort: monitor all system rams
by default" from SeongJae Park simplifies deployment on diverse hardware
like NUMA systems by updating DAMON_RECLAIM and DAMON_LRU_SORT to
automatically monitor the physical address range covering all System RAM
areas by default, replacing the overly restrictive behavior that only
targeted the single largest memory block to save on negligible overhead.
- The 2 patch series "mm/damon/sysfs: document filters/ directory as
deprecated" from SeongJae Park updates some DAMON docs.
- The 8 patch series "mm: use spinlock guards for zone lock" from Dmitry
Ilvokhin switches zone->lock handling over to using the guard()
mechanisms.
- The 2 patch series "mm/filemap: tighten mmap_miss hit accounting" from
fujunjie fixes 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.
- The 2 patch series "selftests/cgroup: Fix false positive failures in
test_percpu_basic" from Li Wang fixes a couple of false-positives in the
cgroup kmem selftests.
- The 2 patch series "mm/damon/reclaim: support monitoring intervals
auto-tuning" from SeongJae Park adds a new parameter to DAMON permitting
DAMON_RECLAIM to automatically tune DAMON's sampling and aggregation
intervals.
- The 2 patch series "mm/damon/stat: add kdamond_pid parameter" from
SeongJae Park chnges DAMON_STAT to provide the pid of its kdamond.
- The 2 patch series "mm/kmemleak: dedupe verbose scan output" from
Breno Leitao removes large amounts of duplicated backtraces from the
verbose-mode kmemleak output.
- The 8 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)"
from David Hildenbrand reduces our use of CONFIG_HAVE_BOOTMEM_INFO_NODE,
with a view to removing it entirely in a later series.
- The 2 patch series "mm/damon: validate min_region_size to be power of
2" from Liew Rui Yan prevents users from passing a non-power-of-2 value
of `addr_unit', as this later results in undesirable behavior.
- The 2 patch series "mm: document read_pages and simplify usage" from
Frederick Mayle does as claimed.
- The 3 patch series "tools/mm/page-types: Fix misc bugs" from Ye Liu
fixes three issues in tools/mm/page-types.c.
- The 4 patch series "mm: misc cleanups from __GFP_UNMAPPED series" from
Brendan Jackman implements several cleanups in the page allocator and
related code.
- The 12 patch series "mm, swap: swap table phase IV: unify allocation"
from Kairui Song unifies the allocation and charging of anon and shmem
swap in folios, provides better synchronization, consolidates the
metadata management, hence dropping the static array and map, and
improves performance.
- The 28 patch series "mm/damon: introduce data attributes monitoring"
from SeongJae Park extends DAMON for monitoring general data attributes
other than accesses.
- The 5 patch series "mm/vmalloc: free unused pages on vrealloc()
shrink" from Shivam Kalra implements the TODO in vrealloc() to unmap and
free unused pages when shrinking across a page boundary.
- The 3 patch series "mm/damon: documentation and comment fixes" from
niecheng does as advertised.
- The 3 patch series "remove mmap_action success, error hooks" from
Lorenzo Stoakes eliminates custom hooks from mmap_action by removing the
problematic success_hook which allowed drivers to improperly access
uninitialized VMAs. It replaces the error_hook with a simple error-code
field and updates the memory char driver accordingly.
- The 14 patch series "mm/damon: minor improvements for code readability
and tests" from SeongJae Park implements minor improvements in code
readability and tests for DAMON.
- The 2 patch series "mm/damon: fix macro arguments and clarify quota
goals doc" from Maksym Shcherba does those things.
- The 2 patch series "userfaultfd: merge fs/userfaultfd.c into
mm/userfaultfd.c" from Mike Rapoport performs that code movement.
- The 15 patch series "mm/mglru: improve reclaim loop and dirty folio"
from Kairui Song and others cleans up and slightly improves MGLRU's
reclaim loop and dirty writeback handling. Large performance
improvements are measured.
- The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}
reads" from Suren Baghdasaryan uses per-vma locks when reading
/proc/pid/smaps and /proc/pid/numa_maps similar to reduce contention on
central mmap_lock.
- The 2 patch series "refactors thpsize_shmem_enabled_store() and
thpsize_shmem_enabled_show()" from Ran Xiaokai provides some cleanup
work in the THP code.
- The 2 patch series "selftests/memfd: fix compilation warnings" from
Konstantin Khorenko fixes a few build glitches in the memfd selftest
code.
- The 4 patch series "memcg: shrink obj_stock_pcp and cache multiple
objcgs" from Shakeel Butt resolves a 68% performance regression caused
by NUMA-node cache thrashing around struct obj_stock_pcp by shrinking
its existing fields and expanding it into a multi-slot array that caches
up to five obj_cgroup pointers per CPU, allowing per-node variants of
the same memcg to coexist within a single 64-byte cache line.
- The 2 patch series "zram: writeback fixes" from Sergey Senozhatsky
addresses a couple of unrelated zram writeback issues.
- The 9 patch series "mm: switch THP shrinker to list_lru" from Johannes
Weiner resolves NUMA-awareness issues and streamlines callsite
interaction by refactoring and extending the list_lru API to completely
replace the complex, open-coded deferred split queue for Transparent
Huge Pages (THPs).
- The 2 patch series "mm: improve large folio readahead for exec memory"
from Usama Arif improves large-folio readahead on systems like 64K-page
arm64 by preventing the mmap_miss check from permanently disabling
target-oriented VM_EXEC readahead, and by generalizing the
force_thp_readahead gate to support mappings with any usefully large
maximum folio order under the cache cap.
- The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
Kiryl Shutsemau fixes a bunch of minor issues in the
userfaultfd/pagemap, all of which were flagged by Sashiko review of
proposed new material.
- The 5 patch series "mm/sparse-vmemmap: Provide generic
vmemmap_set_pmd() and vmemmap_check_pmd()" from Muchun Song provides
generic versions of these two functions so the four arch-specific
implementations can be removed.
- The 2 patch series "mm/swap, PM: hibernate: fix swapoff race in
uswsusp by pinning swap device" from Youngjun Park addresses a
uswsusp-vs-swapoff race and reduces the swap device reference
taking/releasing frequency.
- The 2 patch series "mm/hmm: A fix and a selftest" from Dev Jain does
as claimed.

Arm:
"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.

RISC-V updates for v7.2
- Prevent get_free_mem_region() from returning regions that are
unmappable in certain circumstances by defining
DIRECT_MAP_PHYSMEM_END for RISC-V
- Fix an early boot problem with kexec_file when the amount of
installed physical memory installed on the system exceeds the direct
map size, which is possible in certain RISC-V virtual memory modes
- Unconditionally sfence.vma in the new vmalloc area handling code in
the page fault handler, since even the presence of Svvptc doesn't
guarantee that the CPU won't immediately fault again after the
exception handler completes and subsequently crash
- Fix ftrace_graph_ret_addr() to use the correct task pointer
(aligning with what other architectures do)
- Fix the misaligned access performance checking code in cases when
performance is specified on the kernel command line and when CPUs
have been brought offline and back online
- Get rid of a bogus address offset in the non-frame-pointer version
of walk_stackframe(), aligning it with the frame pointer-based code
- Fix a RISC-V kfence issue causing bogus use-after-free warnings
- Add ARCH_HAS_CC_CAN_LINK for RISC-V, which needs different compiler
command line flags than other architectures
- Implement _THIS_IP_ using RISC-V-specific assembly, which seems to
be less brittle (from a compiler point of view) than taking the
address of a label
- Reduce kernel startup overhead by defining
HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
requirements
- Patch the CFI vDSO during alternatives processing, not only the
standard vDSO
- Fix a potential memory leak in the cacheinfo code
- Clean up kernel/setup.c:add_resource() to pass along the return
value from insert_resource() and to improve the display of
resource ranges
- Clean up our purgatory.[ch] by aligning our purgatory() prototype
to what's in arch/x86, and by cleaning up verify_sha256_digest()
- Clean up cpu_is_stopped() to align its function a little more
closely to its name
- Replace some unbounded string function usage in get_early_cmdline()
and the ptdump code with strscpy()
- Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
safer bounds checking
- Standardize how compiler output flags are specified in the RISC-V
kselftests, aligning them with what other architectures do
- Use the Linux-generic cmp_int() macro in place of an open-coded
"cmp_3way()" macro in kernel/module-sections.c
- Panic early in boot if IRQ handler stacks can't be allocated rather
than pretending to continue normally
- Add support for Eswin SoCs in the RISC-V defconfig
- Remove some unnecessary conditionals in sbi_hsm_hart_{start,stop}()
- Clean up some Kconfig infelicities found by Kconfirm
- Replace an open-coded version of min() in the kexec_elf code with
the standard min() function

HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
requirements
- Patch the CFI vDSO during alternatives processing, not only the
standard vDSO
- Fix a potential memory leak in the cacheinfo code
- Clean up kernel/setup.c:add_resource() to pass along the return value
from insert_resource() and to improve the display of resource ranges
- Clean up our purgatory.[ch] by aligning our purgatory() prototype to
what's in arch/x86, and by cleaning up verify_sha256_digest()
- Clean up cpu_is_stopped() to align its function a little more closely
to its name
- Replace some unbounded string function usage in get_early_cmdline()
and the ptdump code with strscpy()
- Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
safer bounds checking
- Standardize how compiler output flags are specified in the RISC-V
kselftests, aligning them with what other architectures do
- Use the Linux-generic cmp_int() macro in place of an open-coded
"cmp_3way()" macro in kernel/module-sections.c
- Panic early in boot if IRQ handler stacks can't be allocated rather
than pretending to continue normally
- Add support for Eswin SoCs in the RISC-V defconfig
- Remove some unnecessary conditionals in sbi_hsm_hart_{start,stop}()
- Clean up some Kconfig infelicities found by Kconfirm
- Replace an open-coded version of min() in the kexec_elf code with
the standard min() function

selftests/uevent: increase __UEVENT_BUFFER_SIZE to avoid ENOBUFS on busy systems
The kselftests case uevent.uevent_filtering fails reproducibly on busy systems (e.g. Intel EMR / AMD servers) with: No buffer space available - Failed to receive uevent The listener binds the NETLINK_KOBJECT_UEVENT socket to all 32 multicast groups (nl_groups = -1) but only sets SO_RCVBUF to 4 KiB (__UEVENT_BUFFER_SIZE = 2048 * 2). On hosts with many devices, the kernel and userspace daemons (udev/systemd) constantly emit uevents on multiple groups, plus the test itself triggers 10 add events in a row. The 4 KiB receive buffer overflows before the listener can drain it, recvmsg() returns -ENOBUFS, and the test bails out as failure. Increase __UEVENT_BUFFER_SIZE to 1 MiB so the receive buffer is large enough to absorb the burst of uevents on busy systems. After this change the test passes consistently across dozens of runs on Intel EMR and AMD platforms.

VFIO updates for v7.2-rc1
- Fix out-of-tree vfio selftest builds with make O=. (Jason Gunthorpe)
- Allow vfio selftests to build when ARCH=x86 is used for 64-bit x86
builds. (David Matlack)
- Tighten vfio selftest infrastructure with stricter builds, safer
path handling, sysfs helpers, and reusable device/VF-token setup.
Build on that to add the SR-IOV UAPI selftest across supported
IOMMU modes. (Raghavendra Rao Ananta)
- Conclude earlier vfio PCI BAR work already taken as v7.1 fixes by
replacing vfio_pci_core_setup_barmap() and direct barmap[] access
with vfio_pci_core_get_iomap(). Fix resulting sparse warnings.
(Matt Evans)
- Simplify hisi_acc vfio-pci variant driver device-info reads by
using the mailbox's new direct command-based read helper.
(Weili Qian)
- Avoid duplicate reset handling in the Xe vfio-pci variant driver
reset-done path. (GuoHan Zhao)
- Resolve a lockdep circular dependency splat by tracking active
VFs with a private sriov_active flag rather than calling
pci_num_vf() under memory_lock. (Raghavendra Rao Ananta)
- Add CXL DVSEC-based readiness polling for Blackwell-Next in the
nvgrace-gpu vfio-pci variant driver, including interruptible,
lockless waits to support worst case spec defined timeouts.
(Ankit Agrawal)
- Prevent vfio_mig_get_next_state() from spinning forever on blocked
migration state transition. (Junrui Luo)
- Fix a qat vfio variant driver migration resume race by taking the
migration file lock before boundary checks. (Giovanni Cabiddu)
- Add explicit dependencies between vfio selftest output object files
and output directories to ensure directories are always created.
(David Matlack)

sched_ext: Changes for v7.2
This depends on the BPF arena work in bpf-next and should be pulled after
it. for-7.1-fixes was merged in a few times to avoid conflicts with the
feature changes.
- Most of this continues the in-development sub-scheduler support, which
lets a root BPF scheduler delegate to nested sub-schedulers. The
dispatch-path building blocks landed in 7.1. A follow-up patchset in
development will complete enqueue-path support for hierarchical
scheduling. This cycle adds most of that infrastructure:
- Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
so a topology unit becomes a (start, length) slice. Raw CPU numbers
are sparse and don't track topological closeness, which makes them
clumsy for sharding work across sub-schedulers and awkward in BPF.
- cmask: bitmaps windowed over a slice of cid space, so a sub-scheduler
can track, for example, the idle cids of its shard without a full
NR_CPUS cpumask.
- A struct_ops variant that cid-form sub-schedulers register with,
along with the cid-form kfuncs they call.
- BPF arena integration, which sub-scheduler support is built on. The
bpf-next additions let the kernel read and write the BPF scheduler's
arena directly, turning it into a real kernel/BPF shared-memory
channel. Shared state like the per-CPU cmask now lives there.
- scx_qmap is reworked to exercise the new arena and cid interfaces.
- Exit-dump improvements: dump the faulting CPU first, expose the exit
CPU to BPF and userspace, and normalize the dump header.
- Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking on
the error and dump formatters, header reorganization, and assorted
fixes.

"Major changes:
- Recover from BPF arena page faults using a scratch page and add
ptep_try_set() for lockless empty-slot installs on x86 and arm64.
This allows BPF kfuncs to access arena pointers directly.
The 'arena_direct_access' stable branch was created for this work
and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
Kartikeya Dwivedi)
- Lift old restriction and support 6+ arguments in BPF programs and
kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)
Other features and fixes:
- Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
addition of new BTF kinds (Alan Maguire)

maps (Daniel Borkmann)
- Replace the verifier min/max bounds fields with a circular number
(cnum) representation and improve 32->64 bit range refinements
(Eduard Zingerman)

allocator, rbtree and SPMC queue data structures, ASAN support and
a parallel test harness. Allow subprograms to return arena pointers
and switch to a BTF type-tag based __arena annotation (Emil
Tsalapatis)
- Cache build IDs in the sleepable stackmap path and avoid faultable
build ID reads under mm locks (Ihor Solodrai)
- Introduce the tracing_multi link to attach a single BPF program to
many kernel functions at once. Allow specifying the uprobe_multi
target via FD (Jiri Olsa)
- Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
bpf_list_is_first/is_last/empty() (Kaitao Cheng)
- Extend the BPF syscall with common attributes support for
prog_load, btf_load and map_create (Leon Hwang)

LRU map due to NMI reentry (Mykyta Yatsenko)
- Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
arrays, enforce write checks for global subprograms (Nuoqi Gui)
- Report the maximum combined stack depth and print a breakdown of
instructions processed per subprogram (Paul Chaignon)
- Add an XDP load-balancer benchmark and arm64 JIT support for stack
arguments (Puranjay Mohan)
- Add kfuncs to traverse over wakeup_sources (Samuel Wu)

Networking changes for 7.2.
Core & protocols
----------------
- Work on removing rtnl_lock protection throughout the stack continues.
In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even tho
user space wants a dump of all netdevs, most of the time, the OOO
programming model results in repeating the dump for each netdev.
Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on retransmit
timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 > 40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot express
reqid changes or migrate Transport mode selectors. The new interface
identifies the SA via SPI and mark, supports reqid changes, address
family changes, encap removal, and uses an atomic create+install
flow under x->lock to prevent SN/IV reuse during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff
----------------
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto API
users, since it changed crypto transformation objects into reference-
-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the global
crypto API as obsolete and insecure.
Wireless
--------
- Major rework of station bandwidth handling, fixing issues with lower
capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter
---------
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions
---------
- Remove TLS + sockmap integration. TLS wants to pin user pages
to avoid a copy, and sockmap wants to write to the input stream.
More work on this integration is clearly needed, and we can't find
any users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from
the vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM needs,
AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel)
interface in user namespaces. To be deleted completely, soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers

- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for control
objects, save memory on systems with 64kB page size

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers:
- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
- bonding: add knob to strictly follow 802.3ad for link state
- New drivers:
- Alibaba Elastic Ethernet Adaptor (cloud vNIC).
- NXP NETC switch within i.MX94.
- DPLL:
- Add operational state to pins (implement in zl3073x).
- Add generic DPLL type, for daisy-chaining DPLLs (implement in ice).
- Ethernet high-speed NICs:
- Huawei (hinic3):
- enhance tc flow offload support with queue selection,
tunnels
- nVidia/Mellanox:
- avoid over-copying payload to the skb's linear part (up to
60% win for LRO on slow CPUs like ARM64 V2)
- expose more per-queue stats over the standard API
- support additional, unprivileged PFs in the DPU
configuration
- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for
control objects, save memory on systems with 64kB page size
- take advantage of the ability to dynamically change RSS
table size, even when table is configured by the user
- increase the max RSS table size for even traffic
distribution

- Marvell/Aquantia:
- AQC113 PTP support

selftests/bpf: drop the unused kTLS program from test_sockmap
With the sockmap + kTLS tests gone, the BPF-side support in test_sockmap is dead: the tls_sock_map map and bpf_prog3 (which redirected skbs into it) are no longer referenced. Remove them, along with the now-unused bpf_write_pass() helper. bpf_prog3 was progs[2], so renumber the progs[] users in test_sockmap.c: the sockops program drops to progs[2] and the sk_msg tx programs to progs[3..7]. Shrink the map/prog arrays from 9 to 8 and drop the tls_sock_map entry (the last one) from map_names[] to match.

selftests/bpf: remove sockmap + ktls tests
The combination of sockmap and TLS is no longer supported - installing the TLS ULP on a sockmap socket (and vice versa) is now rejected. Remove the tests that exercise the combination along with their BPF program; the file covered nothing but sockmap sockets holding kTLS contexts.

selftests/net: Add netkit io_uring ZC test for large rx_buf_len
Add test_iou_zcrx_large_buf, which runs iou-zcrx with rx_buf_len > page size (-x 2) through a netkit-leased RX queue. The netkit ifindex is opaque to io_uring, but rx_page_size is honoured by the leased physical qops via netif_mp_open_rxq()'s lease redirect. Originally, I also added a BIG TCP variant on top, but dropped it here as fbnic (and the QEMU fbnic model) has no BIG TCP support to exercise it as this point. Tested against the QEMU fbnic emulation. The new test exercises the > page rx_buf_len path only when the leased NIC advertises QCFG_RX_PAGE_SIZE; otherwise it skips. For fbnic, I used Bjorn's patches locally [0]: # ./nk_qlease.py TAP version 13 1..5 ok 1 nk_qlease.test_iou_zcrx ok 2 nk_qlease.test_iou_zcrx_large_buf ok 3 nk_qlease.test_attrs ok 4 nk_qlease.test_attach_xdp_with_mp ok 5 nk_qlease.test_destroy # Totals: pass:5 fail:0 xfail:0 xpass:0 skip:0 error:0 Without those patches (aka not advertising QCFG_RX_PAGE_SIZE): # ./nk_qlease.py TAP version 13 1..5 ok 1 nk_qlease.test_iou_zcrx ok 2 nk_qlease.test_iou_zcrx_large_buf # SKIP Large chunks are not supported -95 ok 3 nk_qlease.test_attrs ok 4 nk_qlease.test_attach_xdp_with_mp ok 5 nk_qlease.test_destroy # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:1 error:0 Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Bobby Eshleman <bobbyeshleman@meta.com> Link: https://lore.kernel.org/netdev/20260522113225.241337-1-bjorn@kernel.org/ [0] Link: https://patch.msgid.link/20260614102607.863838-4-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

The HW counterpart of nk_qlease.py was carrying its lease setup in main()
and stashing src_queue / nk_queue / nk_*_ifname on cfg, which had drawbacks

selftests: net: add local ECMP rehash test
Add ecmp_rehash.sh with nine scenarios verifying that TCP rehash
selects a different local ECMP path for IPv6:
- SYN retransmission (forward path blocked during setup)
- SYN/ACK retransmission (reverse path blocked during setup)
- Midstream RTO (forward path blocked on established connection)
- Midstream ACK rehash (reverse path blocked on established connection)
- PLB rehash (ECN-driven congestion on established connection)
- Hash policy 1 negative test (rehash attempted but path unchanged)
- No flowlabel leak (client mp_hash does not alter on-wire flowlabel)
- Dst rebuild consistency (dst invalidation does not change path)
- Syncookie server path consistency (SYN-ACK and post-cookie ACKs
use the same ECMP path)
The policy 1 test verifies that fib_multipath_hash_policy=1 computes
a deterministic 5-tuple hash, so txhash re-rolls do not change the
ECMP path while TcpTimeoutRehash still increments.
The flowlabel leak test sets auto_flowlabels=0 on the client and
installs tc filters on client egress that drop TCP packets with
nonzero flowlabel, confirming that the client's fl6->mp_hash does
not leak into the on-wire IPv6 flow label.
The PLB test needs DCTCP, a restricted congestion control. Rather
than relax the host-global tcp_allowed_congestion_control (no
per-netns equivalent), it pins dctcp on the test routes via the
congctl route attribute, confined to the test namespaces.
The dst rebuild test streams data, invalidates the cached dst by
adding and removing a dummy route (bumping the fib6_node sernum),
and verifies that traffic stays on the same path. The sernum change
causes ip6_dst_check() to fail on the next transmit, triggering a
fresh route lookup via inet6_csk_route_socket().
ECMP_REBUILD_ROUNDS=10 repeats the check to reduce the probability
of a buggy kernel passing by chance with 2-way ECMP.
The syncookie server path consistency test verifies that the
server's SYN-ACK and subsequent ACKs use the same ECMP path.
With syncookies, the request socket is freed after the SYN-ACK,
so cookie_tcp_reqsk_init() must derive the same txhash (from the
cookie) that was used for the SYN-ACK's route lookup.
The syncookie test forces tcp_syncookies=2; it skips when
CONFIG_SYN_COOKIES is not available. selftests/net/config selects
it (and CONFIG_TCP_CONG_DCTCP for the PLB test).

selftests/vsock: accept vng 1.33 or >= 1.36
The current vng version check uses a discrete allowlist of "1.33", "1.36", and "1.37", which forces a script update on every new release even though all post-1.36 releases work. Replace the discrete list with: "1.33", or any version >= 1.36. 1.34 and 1.35 are skipped because they were not tested. Add a version_lt() helper that compares MAJOR.MINOR numerically, so the check reads as a straightforward version comparison.

Pull scheduler updates from Ingo Molnar:
"SMP load-balancing updates:
- A large series to introduce infrastructure for cache-aware load
balancing, with the goal of co-locating tasks that share data
within the same Last Level Cache (LLC) domain. By improving cache
locality, the scheduler can reduce cache bouncing and cache misses,
ultimately improving data access efficiency.
Implemented by Chen Yu and Tim Chen, based on early prototype work
by Peter Zijlstra, with fixes by Jianyong Wu, Peter Zijlstra and
Shrikanth Hegde.

Locking updates for v7.2:
Futex updates:
- Optimize futex hash bucket access patterns (Peter Zijlstra)
- Large series to address the robust futex unlock race for real,
by Thomas Gleixner:
"The robust futex unlock mechanism is racy in respect
to the clearing of the robust_list_head::list_op_pending
pointer because unlock and clearing the pointer are not
atomic. The race window is between the unlock and clearing the
pending op pointer. If the task is forced to exit in this
window, exit will access a potentially invalid pending op
pointer when cleaning up the robust list. That happens if
another task manages to unmap the object containing the lock
before the cleanup, which results in an UAF. In the worst case
this UAF can lead to memory corruption when unrelated content
has been mapped to the same address by the time the access
happens.
User space can't solve this problem without help from the kernel.
This series provides the kernel side infrastructure to help it
along:
1) Combined unlock, pointer clearing, wake-up for the
contended case
2) VDSO based unlock and pointer clearing helpers with a
fix-up function in the kernel when user space was interrupted
within the critical section.

- Add a note about robust list race condition (André Almeida)

Guard infrastructure updates:
- Series to remove NULL check from unconditional guards

Lockdep updates:
- Restore self-test migrate_disable() and sched_rt_mutex
state on PREEMPT_RT (Karl Mehltretter)
Membarriers updates:
- Use per-CPU mutexes for targeted commands (Aniket Gattani)
- Modernize membarrier_global_expedited with cleanup guards

Updates for the time/timer core subsystem:
- Harden the user space controllable hrtimer interfaces further to
protect against unpriviledged DoS attempts by arming timers in the past.
- Add per-capacity hierarchies to the timer migration code to prevent
timer migration accross different capacity domains. This code has been
disabled last minute as there is a pathological problem with SoCs which
advertise a larger number of capacity domains. The problem is under
investigation and the code won't be active before v7.3, but that turned
out to be less intrusive than a full revert as it preserves the
preparatory steps and allows people to work on the final resolution
- Export time namespace functionality as a recent user can be built as a
module.
- Initialize the jiffies clocksource before using it. The recent
hardening against time moving backward requires that the related
members of struct clocksource have been initialized, otherwise it
clamps the readout to 0, which makes time stand sill and causes boot
delays.
- Fix a more than twenty year old PID reference count leak in an error
path of the POSIX CPU timer code.
- The usual small fixes, improvements and cleanups all over the place.

selftests/bpf: Work around llvm stack overflow in crypto progs
clang 23 fails to build crypto_bench.c and crypto_sanity.c with "BPF stack limit exceeded". The progs fill a 408-byte bpf_crypto_params on the stack and pass it to bpf_crypto_ctx_create(). clang 23 copies the byte-aligned cipher/key globals into it one byte at a time through the stack, and keeps more than one copy of the struct around. Together that blows the 512-byte limit. Align the source arrays to 8 bytes so the copy is word-wise, and move params off the stack into a static .bss var. static keeps it out of the skeleton, where bpf_crypto_params is an incomplete type. Either change alone is not enough. Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

selftsets/bpf: Retry map update on helper_fill_hashmap()
helper_fill_hashmap() is used also on parallel and stress map tests. Those are consistently failing with ENOMEM on kernels built with PREEMPT_RT if preallocation is disabled. The failure is transient and only called by the memory cache refill running in a preemptible irq_work, which can easily stall in case of contention. Use a retriable update in those cases to handle transient ENOMEM and make the test more stable also on PREEMPT_RT. Also fix the sign of the value printed in case of error (strerror() expects a positive errno while updates return it negative).

Merge tag 'rcu.release.v7.2' of gitolite.kernel.org:pub/scm/linux/kernel/git/rcu/linux
Pull RCU updates from Uladzislau Rezki:
"Torture test updates:
- Improve kvm-series.sh script by adding examples in its header
comment
- Lazy RCU is more fully tested now by replacing call_rcu_hurry()
with call_rcu() and doing rcu_barrier() to motivate lazy callbacks
during a stutter pause
- Add more synonyms for the "--do-normal" group of torture.sh
command-line arguments
Misc changes:
- Reduce stack usage of nocb_gp_wait() to address frame size warning
when built with CONFIG_UBSAN_ALIGNMENT
- The synchronize_rcu() call can detect the flood and latches a
normal/default path temporary switching to wait_rcu_gp() path
- Document using rcu_access_pointer() to fetch the old pointer for
lockless cmpxchg() updates
- Simplify some RCU code using clamp_val()
- Fix a kerneldoc header comment typo in srcu_down_read_fast()"
