drm/xe/uapi: Extend the madvise functionality to support foreign pagemap placement for svm
Use device file descriptors and regions to represent pagemaps on foreign or local devices. The underlying files are type-checked at madvise time, and references are kept on the drm_pagemap as long as there is are madvises pointing to it. Extend the madvise preferred_location UAPI to support the region instance to identify the foreign placement. v2: - Improve UAPI documentation. (Matt Brost) - Sanitize preferred_mem_loc.region_instance madvise. (Matt Brost) - Clarify madvise drm_pagemap vs xe_pagemap refcounting. (Matt Brost) - Don't allow a foreign drm_pagemap madvise without a fast interconnect. v3: - Add a comment about reference-counting in xe_devmem_open() and remove the reference-count get-and-put.

block: add allocation size check in blkdev_pr_read_keys()
blkdev_pr_read_keys() takes num_keys from userspace and uses it to
calculate the allocation size for keys_info via struct_size(). While
there is a check for SIZE_MAX (integer overflow), there is no upper
bound validation on the allocation size itself.
A malicious or buggy userspace can pass a large num_keys value that
doesn't trigger overflow but still results in an excessive allocation
attempt, causing a warning in the page allocator when the order exceeds
MAX_PAGE_ORDER.
Fix this by introducing PR_KEYS_MAX to limit the number of keys to
a sane value. This makes the SIZE_MAX check redundant, so remove it.
Also switch to kvzalloc/kvfree to handle larger allocations gracefully.

sound fixes for 6.19-rc1
The rest for 6.19 merge window. The only slightly large change is
the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio
- HD-audio Intel binding fix and quirks

drm/xe/multi_queue: Add user interface for multi queue support
Multi Queue is a new mode of execution supported by the compute and
blitter copy command streamers (CCS and BCS, respectively). It is an
enhancement of the existing hardware architecture and leverages the
same submission model. It enables support for efficient, parallel
execution of multiple queues within a single context. All the queues
of a group must use the same address space (VM).
The new DRM_XE_EXEC_QUEUE_SET_PROPERTY_MULTI_QUEUE execution queue
property supports creating a multi queue group and adding queues to
a queue group. All queues of a multi queue group share the same
context.
A exec queue create ioctl call with above property specified with value
DRM_XE_SUPER_GROUP_CREATE will create a new multi queue group with the
queue being created as the primary queue (aka q0) of the group. To add
secondary queues to the group, they need to be created with the above
property with id of the primary queue as the value. The properties of
the primary queue (like priority, timeslice) applies to the whole group.
So, these properties can't be set for secondary queues of a group.
Once destroyed, the secondary queues of a multi queue group can't be
replaced. However, they can be dynamically added to the group up to a
total of 64 queues per group. Once the primary queue is destroyed,
secondary queues can't be added to the queue group.
v2: Remove group->lock, fix xe_exec_queue_group_add()/delete()
function semantics, add additional comments, remove unused
group->list_lock, add XE_BO_FLAG_GGTT_INVALIDATE for cgp bo,
Assert LRC is valid, update uapi kernel doc.

v3: Use XE_BO_FLAG_PINNED_LATE_RESTORE/USER_VRAM/GGTT_INVALIDATE

mptcp: pm: ignore unknown endpoint flags
Before this patch, the kernel was saving any flags set by the userspace,
even unknown ones. This doesn't cause critical issues because the kernel
is only looking at specific ones. But on the other hand, endpoints dumps
could tell the userspace some recent flags seem to be supported on older
kernel versions.
Instead, ignore all unknown flags when parsing them. By doing that, the
userspace can continue to set unsupported flags, but it has a way to
verify what is supported by the kernel.
Note that it sounds better to continue accepting unsupported flags not
to change the behaviour, but also that eases things on the userspace
side by adding "optional" endpoint types only supported by newer kernel
versions without having to deal with the different kernel versions.
A note for the backports: there will be conflicts in mptcp.h on older
versions not having the mentioned flags, the new line should still be
added last, and the '5' needs to be adapted to have the same value as
the last entry.

This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/

Merge tag 'tsm-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm
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

51d90a15fe |
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.

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"

vfs: use UAPI types for new struct delegation definition
Using libc types and headers from the UAPI headers is problematic as it introduces a dependency on a full C toolchain. Use the fixed-width integer types provided by the UAPI headers instead. Fixes: |
