NFSD 6.19 Release Notes
Mike Snitzer's mechanism for disabling I/O caching introduced in
v6.18 is extended to include using direct I/O. The goal is to
further reduce the memory footprint consumed by NFS clients
accessing large data sets via NFSD.
The NFSD community adopted a maintainer entry profile during this
cycle. See
Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst
Work continues on hardening NFSD's implementation of the pNFS block
layout type. This type enables pNFS clients to directly access the
underlying block devices that contain an exported file system,
reducing server overhead and increasing data throughput.
The remaining patches in this pull request are clean-ups and minor
optimizations. Many thanks to the contributors, reviewers, testers,
and bug reporters who participated during the v6.19 NFSD development
cycle.

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.
This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.
PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.
The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.
Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".
That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.
This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).
In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.
Summary:
- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure
- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture
- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport
- Add skeleton support for 'bind' and 'guest_request' operations in

Modules changes for v6.19-rc1
Rust module parameter support: - Add Rust module parameter support, enabling Rust kernel modules to declare and use module parameters. The rust_minimal sample module demonstrates this, and the rust null block driver will be the first to use it in the next cycle. This also adds the Rust module files under the modules subsystem as agreed between the Rust and modules maintainers. Hardening: - Add compile-time check for embedded NUL characters in MODULE_*() macros. This module metadata was once used (and maybe still) to bypass license enforcement (LWN article [1] from 2003). This change required a sparse fix [2] which you reviewed. MAINTAINERS: - Add Aaron Tomlin as reviewer for the Modules subsystem. The changes have been in linux-next for 4 weeks. Recent 0day reports for UM [3] and arm64 [4] builds were not reproducible and traced to a buggy bindgen version combined with unreleased clang-22 in 0day. The Rust team has reported this to 0day. As discussed previously, we rotate module maintainership among co-maintainers every 6 months. Sami Tolvanen is next in line and will send the next pull request. As a reminder, Luis has already announced [5] he will gradually step away as maintainer.

gpio: tb10x: fix OF_GPIO dependency
Selecting OF_GPIO is generally not allowed, it always gets enabled
when both GPIOLIB and OF are turned on.
The tb10x driver now warns about this after it was enabled for
compile-testing:
WARNING: unmet direct dependencies detected for OF_GPIO
Depends on [n]: GPIOLIB [=y] && OF [=n] && HAS_IOMEM [=y]
Selected by [y]:
- GPIO_TB10X [=y] && GPIOLIB [=y] && HAS_IOMEM [=y] && (ARC_PLAT_TB10X || COMPILE_TEST [=y])
OF_GPIO is not required for compile-testing and is already enabled
when the driver is usable, so just drop the 'select' line.

sched/core: Fix psi_dequeue() for Proxy Execution
Currently, if the sleep flag is set, psi_dequeue() doesn't
change any of the psi_flags.
This is because psi_task_switch() will clear TSK_ONCPU as well
as other potential flags (TSK_RUNNING), and the assumption is
that a voluntary sleep always consists of a task being dequeued
followed shortly there after with a psi_sched_switch() call.
Proxy Execution changes this expectation, as mutex-blocked tasks
that would normally sleep stay on the runqueue. But in the case
where the mutex-owning task goes to sleep, or the owner is on a
remote cpu, we will then deactivate the blocked task shortly
after.
In that situation, the mutex-blocked task will have had its
TSK_ONCPU cleared when it was switched off the cpu, but it will
stay TSK_RUNNING. Then if we later dequeue it (as currently done
if we hit a case find_proxy_task() can't yet handle, such as the
case of the owner being on another rq or a sleeping owner)
psi_dequeue() won't change any state (leaving it TSK_RUNNING),
as it incorrectly expects a psi_task_switch() call to
immediately follow.
Later on when the task get woken/re-enqueued, and psi_flags are
set for TSK_RUNNING, we hit an error as the task is already
TSK_RUNNING:
psi: inconsistent task state! task=188:kworker/28:0 cpu=28 psi_flags=4 clear=0 set=4
To resolve this, extend the logic in psi_dequeue() so that
if the sleep flag is set, we also check if psi_flags have
TSK_ONCPU set (meaning the psi_task_switch is imminent) before
we do the shortcut return.
If TSK_ONCPU is not set, that means we've already switched away,
and this psi_dequeue call needs to clear the flags.

sched/fair: Fix unfairness caused by stalled tg_load_avg_contrib when the last task migrates out
When a task is migrated out, there is a probability that the tg->load_avg
value will become abnormal. The reason is as follows:
1. Due to the 1ms update period limitation in update_tg_load_avg(), there
is a possibility that the reduced load_avg is not updated to tg->load_avg
when a task migrates out.
2. Even though __update_blocked_fair() traverses the leaf_cfs_rq_list and
calls update_tg_load_avg() for cfs_rqs that are not fully decayed, the key
function cfs_rq_is_decayed() does not check whether
cfs->tg_load_avg_contrib is null. Consequently, in some cases,
__update_blocked_fair() removes cfs_rqs whose avg.load_avg has not been
updated to tg->load_avg.
Add a check of cfs_rq->tg_load_avg_contrib in cfs_rq_is_decayed(),
which fixes the case (2.) mentioned above.

sched/rt: Remove a preempt-disable section in rt_mutex_setprio()
rt_mutex_setprio() has only one caller: rt_mutex_adjust_prio(). It
expects that task_struct::pi_lock and rt_mutex_base::wait_lock are held.
Both locks are raw_spinlock_t and are acquired with disabled interrupts.
Nevertheless rt_mutex_setprio() disables preemption while invoking
__balance_callbacks() and raw_spin_rq_unlock(). Even if one of the
balance callbacks unlocks the rq then it must not enable interrupts
because rt_mutex_base::wait_lock is still locked.
Therefore interrupts should remain disabled and disabling preemption is
not needed.

sched/hrtick: Fix hrtick() vs. scheduling context
The sched_class::task_tick() method is called on the donor sched_class, and sched_tick() hands it rq->donor as argument, which is consistent. However, while hrtick() uses the donor sched_class, it then passes rq->curr, which is inconsistent. Fix it.

ata fix for 6.19-rc1
- The DELLBOSS VD SATA controller times out when sending I/Os of size
4096 KiB or larger, even though it claims LBA48 support, which per
the ACS standard requires support for a maximum command size of
65535 sectors, i.e. 32 MiB - 512. Thus, quirk the device so that it
sets a lower maximum command size (me)

LoongArch: Add adaptive CSR accessors for 32BIT/64BIT
32BIT platforms only have 32bit CSR/IOCSR registers, 64BIT platforms have both 32bit/64bit CSR/IOCSR registers. Now there are both 32bit and 64bit CSR accessors: csr_read32()/csr_write32()/csr_xchg32(); csr_read64()/csr_write64()/csr_xchg64(); Some CSR registers (address and timer registers) are 32bit length on 32BIT platform and 64bit length on 64BIT platform. To avoid #ifdefs here and there, they need adaptive accessors, so we define and use: csr_read()/csr_write()/csr_xchg(); IOCSR doesn't have a "natural length", which means a 64bit register can be treated as two 32bit registers, so we just use two 32bit accessors to emulate a 64bit accessors.

soc: driver updates for 6.19, part 2
These updates came a little late, or were based on a later 6.18-rc
tag than the others:
- A new driver for cache management on cxl devices with memory shared
in a coherent cluster. This is part of the drivers/cache/ tree, but
unlike the other drivers that back the dma-mapping interfaces, this
one is needed only during CPU hotplug.
- A shared branch for reset controllers using swnode infrastructure
- Added support for new SoC variants in the Amlogic soc_device
identification
- Minor updates in Freescale, Microchip, Samsung, and Apple SoC drivers

soc: sew SoC familes for 6.19
These three new families of SoC are split out into a separate branch
because they touch multiple parts of the source tree and are better
left separate for the initial merge.
- Black Sesame Technologies C1200 is an automotive SoC using
Cortex-A78 CPU cores
- Anlogic dr1v90 (not to be confused with Amlogic) is an FPGA
platform using a single nuclei ux900 RISC-V core
- Tenstorrent Blackhole is a Neural Processing Unit using
custom "Tensix" cores for computation offload managed by
Linux running on SiFive X280 RISC-V cores.
Support for all three is rather rudimentary at the moment and will get
improved as device drivers are merged through other tree.

Pull new SoC families update from Arnd Bergmann:
"These three new families of SoC are split out into a separate branch
because they touch multiple parts of the source tree and are better
left separate for the initial merge.
- Black Sesame Technologies C1200 is an automotive SoC using
Cortex-A78 CPU cores
- Anlogic dr1v90 (not to be confused with Amlogic) is an FPGA
platform using a single nuclei ux900 RISC-V core
- Tenstorrent Blackhole is a Neural Processing Unit using custom
"Tensix" cores for computation offload managed by Linux running on
SiFive X280 RISC-V cores.
Support for all three is rather rudimentary at the moment and will get
improved as device drivers are merged through other tree"

soc: devicetree updates for 6.19
Three new SoCs got added in existing arm64 chip families:
- Renesas R-Car X5H (R8A78000) is a new generation of automotive SoCs,
based on 16 Cortex-A720 (Armv9.2) cores, which makes the the currently
highest-perforance embedded SoC.
- TI AM62L is a new variant of the AM62 family of industrial SoCs, this
one comes without a GPU.
- Qualcomm MSM8937 (Snapdragon 430) is an older mobile phone chip based
on Cortex-A53, and closely related to MSM8917 (Snapdragn 425), which we
already support.
In addition, there are a good number of newly supported machines
across SoC families:
- Two Aspeed AST2600 (Cortex-A7) based BMC setups for large servers
- Mobile Phones and tables based on Mediatek MT6582, Nvidia Tegra124,
Qualcomm MSM8937 and Qualcomm MSM8939,
- Two Laptops based on Qualcomm SoCs: one using the older sdm850, the
other using x1p42100.
- One Router based on Rockchips RK3568
- 24 variants of the Enclustra Mercury system-on-module, all based on
32-bit Intel/Altera SocFPGA chips, plus two boards using 64-bit
SocFPGA Agilex chips..
- 30 industrial/embedded boards and single-board computers, using
various chips from NXP, Rockchips, Mediatek, TI, Amlogic, Qualcomm,
Spacemit, and Starfive.
In total there are 783 commits here, the majority of these improving
hardware support and cleaning up devicetree files across the tree, with
the majority of the changes going into the Qualcomm, NXP, Renesas and
Rockchips platforms.

ARM:
- Support for userspace handling of synchronous external aborts (SEAs),
allowing the VMM to potentially handle the abort in a non-fatal
manner.
- Large rework of the VGIC's list register handling with the goal of
supporting more active/pending IRQs than available list registers in
hardware. In addition, the VGIC now supports EOImode==1 style
deactivations for IRQs which may occur on a separate vCPU than the
one that acked the IRQ.
- Support for FEAT_XNX (user / privileged execute permissions) and
FEAT_HAF (hardware update to the Access Flag) in the software page
table walkers and shadow MMU.
- Allow page table destruction to reschedule, fixing long need_resched
latencies observed when destroying a large VM.
- Minor fixes to KVM and selftests
Loongarch:
- Get VM PMU capability from HW GCFG register.
- Add AVEC basic support.
- Use 64-bit register definition for EIOINTC.
- Add KVM timer test cases for tools/selftests.
RISC/V:
- SBI message passing (MPXY) support for KVM guest
- Give a new, more specific error subcode for the case when in-kernel
AIA virtualization fails to allocate IMSIC VS-file
- Support KVM_DIRTY_LOG_INITIALLY_SET, enabling dirty log gradually
in small chunks
- Fix guest page fault within HLV* instructions
- Flush VS-stage TLB after VCPU migration for Andes cores
s390:
- Always allocate ESCA (Extended System Control Area), instead of
starting with the basic SCA and converting to ESCA with the
addition of the 65th vCPU. The price is increased number of
exits (and worse performance) on z10 and earlier processor;
ESCA was introduced by z114/z196 in 2010.
- VIRT_XFER_TO_GUEST_WORK support
- Operation exception forwarding support
- Cleanups
x86:
- Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO SPTE
caching is disabled, as there can't be any relevant SPTEs to zap.
- Relocate a misplaced export.
- Fix an async #PF bug where KVM would clear the completion queue when the
guest transitioned in and out of paging mode, e.g. when handling an SMI and
then returning to paged mode via RSM.
- Leave KVM's user-return notifier registered even when disabling
virtualization, as long as kvm.ko is loaded. On reboot/shutdown, keeping
the notifier registered is ok; the kernel does not use the MSRs and the
callback will run cleanly and restore host MSRs if the CPU manages to
return to userspace before the system goes down.
- Use the checked version of {get,put}_user().
- Fix a long-lurking bug where KVM's lack of catch-up logic for periodic APIC
timers can result in a hard lockup in the host.
- Revert the periodic kvmclock sync logic now that KVM doesn't use a
clocksource that's subject to NTP corrections.
- Clean up KVM's handling of MMIO Stale Data and L1TF, and bury the latter
behind CONFIG_CPU_MITIGATIONS.
- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast path;
the only reason they were handled in the fast path was to paper of a bug
in the core #MC code, and that has long since been fixed.
- Add emulator support for AVX MOV instructions, to play nice with emulated
devices whose guest drivers like to access PCI BARs with large multi-byte
instructions.
x86 (AMD):
- Fix a few missing "VMCB dirty" bugs.
- Fix the worst of KVM's lack of EFER.LMSLE emulation.
- Add AVIC support for addressing 4k vCPUs in x2AVIC mode.
- Fix incorrect handling of selective CR0 writes when checking intercepts
during emulation of L2 instructions.
- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32] on
VMRUN and #VMEXIT.
- Fix a bug where KVM corrupt the guest code stream when re-injecting a soft
interrupt if the guest patched the underlying code after the VM-Exit, e.g.
when Linux patches code with a temporary INT3.
- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits to
userspace, and extend KVM "support" to all policy bits that don't require
any actual support from KVM.
x86 (Intel):
- Use the root role from kvm_mmu_page to construct EPTPs instead of the
current vCPU state, partly as worthwhile cleanup, but mostly to pave the
way for tracking per-root TLB flushes, and elide EPT flushes on pCPU
migration if the root is clean from a previous flush.
- Add a few missing nested consistency checks.
- Rip out support for doing "early" consistency checks via hardware as the
functionality hasn't been used in years and is no longer useful in general;
replace it with an off-by-default module param to WARN if hardware fails
a check that KVM does not perform.
- Fix a currently-benign bug where KVM would drop the guest's SPEC_CTRL[63:32]
on VM-Enter.
- Misc cleanups.
- Overhaul the TDX code to address systemic races where KVM (acting on behalf
of userspace) could inadvertantly trigger lock contention in the TDX-Module;
KVM was either working around these in weird, ugly ways, or was simply
oblivious to them (though even Yan's devilish selftests could only break
individual VMs, not the host kernel)
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a TDX vCPU,
if creating said vCPU failed partway through.
- Fix a few sparse warnings (bad annotation, 0 != NULL).
- Use struct_size() to simplify copying TDX capabilities to userspace.
- Fix a bug where TDX would effectively corrupt user-return MSR values if the
TDX Module rejects VP.ENTER and thus doesn't clobber host MSRs as expected.
Selftests:
- Fix a math goof in mmu_stress_test when running on a single-CPU system/VM.
- Forcefully override ARCH from x86_64 to x86 to play nice with specifying
ARCH=x86_64 on the command line.
- Extend a bunch of nested VMX to validate nested SVM as well.
- Add support for LA57 in the core VM_MODE_xxx macro, and add a test to
verify KVM can save/restore nested VMX state when L1 is using 5-level
paging, but L2 is not.
- Clean up the guest paging code in anticipation of sharing the core logic for
nested EPT and nested NPT.
guest_memfd:
- Add NUMA mempolicy support for guest_memfd, and clean up a variety of
rough edges in guest_memfd along the way.
- Define a CLASS to automatically handle get+put when grabbing a guest_memfd
from a memslot to make it harder to leak references.
- Enhance KVM selftests to make it easer to develop and debug selftests like
those added for guest_memfd NUMA support, e.g. where test and/or KVM bugs
often result in hard-to-debug SIGBUS errors.
- Misc cleanups.
Generic:
- Use the recently-added WQ_PERCPU when creating the per-CPU workqueue for
irqfd cleanup.
- Fix a goof in the dirty ring documentation.
- Fix choice of target for directed yield across different calls to
kvm_vcpu_on_spin(); the function was always starting from the first
vCPU instead of continuing the round-robin search.

- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast
path; the only reason they were handled in the fast path was to
paper of a bug in the core #MC code, and that has long since been
fixed
- Add emulator support for AVX MOV instructions, to play nice with
emulated devices whose guest drivers like to access PCI BARs with
large multi-byte instructions
x86 (AMD):
- Fix a few missing "VMCB dirty" bugs
- Fix the worst of KVM's lack of EFER.LMSLE emulation
- Add AVIC support for addressing 4k vCPUs in x2AVIC mode
- Fix incorrect handling of selective CR0 writes when checking
intercepts during emulation of L2 instructions
- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]
on VMRUN and #VMEXIT
- Fix a bug where KVM corrupt the guest code stream when re-injecting
a soft interrupt if the guest patched the underlying code after the
VM-Exit, e.g. when Linux patches code with a temporary INT3
- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits
to userspace, and extend KVM "support" to all policy bits that
don't require any actual support from KVM
x86 (Intel):
- Use the root role from kvm_mmu_page to construct EPTPs instead of
the current vCPU state, partly as worthwhile cleanup, but mostly to
pave the way for tracking per-root TLB flushes, and elide EPT
flushes on pCPU migration if the root is clean from a previous
flush
- Add a few missing nested consistency checks
- Rip out support for doing "early" consistency checks via hardware
as the functionality hasn't been used in years and is no longer
useful in general; replace it with an off-by-default module param
to WARN if hardware fails a check that KVM does not perform
- Fix a currently-benign bug where KVM would drop the guest's
SPEC_CTRL[63:32] on VM-Enter
- Misc cleanups
- Overhaul the TDX code to address systemic races where KVM (acting
on behalf of userspace) could inadvertantly trigger lock contention
in the TDX-Module; KVM was either working around these in weird,
ugly ways, or was simply oblivious to them (though even Yan's
devilish selftests could only break individual VMs, not the host
kernel)
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a
TDX vCPU, if creating said vCPU failed partway through
- Fix a few sparse warnings (bad annotation, 0 != NULL)
- Use struct_size() to simplify copying TDX capabilities to userspace
- Fix a bug where TDX would effectively corrupt user-return MSR
values if the TDX Module rejects VP.ENTER and thus doesn't clobber
host MSRs as expected
Selftests:
- Fix a math goof in mmu_stress_test when running on a single-CPU
system/VM
- Forcefully override ARCH from x86_64 to x86 to play nice with
specifying ARCH=x86_64 on the command line
- Extend a bunch of nested VMX to validate nested SVM as well
- Add support for LA57 in the core VM_MODE_xxx macro, and add a test
to verify KVM can save/restore nested VMX state when L1 is using
5-level paging, but L2 is not
- Clean up the guest paging code in anticipation of sharing the core
logic for nested EPT and nested NPT
guest_memfd:
- Add NUMA mempolicy support for guest_memfd, and clean up a variety
of rough edges in guest_memfd along the way
- Define a CLASS to automatically handle get+put when grabbing a
guest_memfd from a memslot to make it harder to leak references
- Enhance KVM selftests to make it easer to develop and debug
selftests like those added for guest_memfd NUMA support, e.g. where
test and/or KVM bugs often result in hard-to-debug SIGBUS errors
- Misc cleanups
Generic:
- Use the recently-added WQ_PERCPU when creating the per-CPU
workqueue for irqfd cleanup
- Fix a goof in the dirty ring documentation
- Fix choice of target for directed yield across different calls to
kvm_vcpu_on_spin(); the function was always starting from the first
vCPU instead of continuing the round-robin search"

nfs/localio: remove 61 byte hole from needless ____cacheline_aligned
struct nfs_local_kiocb used ____cacheline_aligned on its iters[] array
and as the structure evolved it caused a 61 byte hole to form. Fix
this by removing ____cacheline_aligned and reordering iters[] before
iter_is_dio_aligned[].

nfs/localio: remove alignment size checking in nfs_is_local_dio_possible
This check to ensure dio_offset_align isn't larger than PAGE_SIZE is
no longer relevant (older iterations of NFS Direct was allocating
misaligned head and tail pages but no longer does, so this check isn't
needed).
