KVM x86 changes for 6.18
- Don't (re)check L1 intercepts when completing userspace I/O to fix a flaw
where a misbehaving usersepace (a.k.a. syzkaller) could swizzle L1's
intercepts and trigger a variety of WARNs in KVM.
- Emulate PERF_CNTR_GLOBAL_STATUS_SET for PerfMonV2 guests, as the MSR is
supposed to exist for v2 PMUs.
- Allow Centaur CPU leaves (base 0xC000_0000) for Zhaoxin CPUs.
- Clean up KVM's vector hashing code for delivering lowest priority IRQs.
- Clean up the fastpath handler code to only handle IPIs and WRMSRs that are
actually "fast", as opposed to handling those that KVM _hopes_ are fast, and
in the process of doing so add fastpath support for TSC_DEADLINE writes on
AMD CPUs.
- Clean up a pile of PMU code in anticipation of adding support for mediated
vPMUs.
- Add support for the immediate forms of RDMSR and WRMSRNS, sans full
emulator support (KVM should never need to emulate the MSRs outside of
forced emulation and other contrived testing scenarios).
- Clean up the MSR APIs in preparation for CET and FRED virtualization, as
well as mediated vPMU support.
- Rejecting a fully in-kernel IRQCHIP if EOIs are protected, i.e. for TDX VMs,
as KVM can't faithfully emulate an I/O APIC for such guests.
- KVM_REQ_MSR_FILTER_CHANGED into a generic RECALC_INTERCEPTS in preparation
for mediated vPMU support, as KVM will need to recalculate MSR intercepts in
response to PMU refreshes for guests with mediated vPMUs.
- Misc cleanups and minor fixes.

HEAD
KVM SEV-SNP CipherText Hiding support for 6.18
Add support for SEV-SNP's CipherText Hiding, an opt-in feature that prevents
unauthorized CPU accesses from reading the ciphertext of SNP guest private
memory, e.g. to attempt an offline attack. Instead of ciphertext, the CPU
will always read back all FFs when CipherText Hiding is enabled.
Add new module parameter to the KVM module to enable CipherText Hiding and
control the number of ASIDs that can be used for VMs with CipherText Hiding,
which is in effect the number of SNP VMs. When CipherText Hiding is enabled,
the shared SEV-ES/SEV-SNP ASID space is split into separate ranges for SEV-ES
and SEV-SNP guests, i.e. ASIDs that can be used for CipherText Hiding cannot
be used to run SEV-ES guests.

|
KVM SVM changes for 6.18
- Require a minimum GHCB version of 2 when starting SEV-SNP guests via
KVM_SEV_INIT2 so that invalid GHCB versions result in immediate errors
instead of latent guest failures.
- Add support for Secure TSC for SEV-SNP guests, which prevents the untrusted
host from tampering with the guest's TSC frequency, while still allowing the
the VMM to configure the guest's TSC frequency prior to launch.
- Mitigate the potential for TOCTOU bugs when accessing GHCB fields by
wrapping all accesses via READ_ONCE().
- Validate the XCR0 provided by the guest (via the GHCB) to avoid tracking a
bogous XCR0 value in KVM's software model.
- Save an SEV guest's policy if and only if LAUNCH_START fully succeeds to
avoid leaving behind stale state (thankfully not consumed in KVM).
- Explicitly reject non-positive effective lengths during SNP's LAUNCH_UPDATE
instead of subtly relying on guest_memfd to do the "heavy" lifting.
- Reload the pre-VMRUN TSC_AUX on #VMEXIT for SEV-ES guests, not the host's
desired TSC_AUX, to fix a bug where KVM could clobber a different vCPU's
TSC_AUX due to hardware not matching the value cached in the user-return MSR
infrastructure.
- Enable AVIC by default for Zen4+ if x2AVIC (and other prereqs) is supported,
and clean up the AVIC initialization code along the way.
|
|
KVM VMX changes for 6.18
- Add read/write helpers for MSRs that need to be accessed with preemption
disable to prepare for virtualizing FRED RSP0.
- Fix a bug where KVM would return 0/success from __tdx_bringup() on error,
i.e. where KVM would load with enable_tdx=true despite TDX not being usable.
- Minor cleanups.
|
|
KVM x86 MMU changes for 6.18
- Recover possible NX huge pages within the TDP MMU under read lock to
reduce guest jitter when restoring NX huge pages.
- Return -EAGAIN during prefault if userspace concurrently deletes/moves the
relevant memslot to fix an issue where prefaulting could deadlock with the
memslot update.
- Don't retry in TDX's anti-zero-step mitigation if the target memslot is
invalid, i.e. is being deleted or moved, to fix a deadlock scenario similar
to the aforementioned prefaulting case.
|
|
KVM common changes for 6.18
Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as __GFP_NOWARN is
now included in GFP_NOWAIT.
|
|
x86/kvm guest side changes for 6.18
- For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
overriding guest MTRR for TDX/SNP to fix an issue where ACPI auto-mapping
could map devices as WB and prevent the device drivers from mapping their
devices with UC/UC-.
- Make kvm_async_pf_task_wake() a local static helper and remove its
export.
- Use native qspinlocks when running in a VM with dedicated vCPU=>pCPU
bindings even when PV_UNHALT is unsupported.
|
|
KVM selftests changes for 6.18
- Add #DE coverage in the fastops test (the only exception that's guest-
triggerable in fastop-emulated instructions).
- Fix PMU selftests errors encountered on Granite Rapids (GNR), Sierra
Forest (SRF) and Clearwater Forest (CWF).
- Minor cleanups and improvements

KVM/arm64 updates for 6.18
- Add support for FF-A 1.2 as the secure memory conduit for pKVM,
allowing more registers to be used as part of the message payload.
- Change the way pKVM allocates its VM handles, making sure that the
privileged hypervisor is never tricked into using uninitialised
data.
- Speed up MMIO range registration by avoiding unnecessary RCU
synchronisation, which results in VMs starting much quicker.
- Add the dump of the instruction stream when panic-ing in the EL2
payload, just like the rest of the kernel has always done. This will
hopefully help debugging non-VHE setups.
- Add 52bit PA support to the stage-1 page-table walker, and make use
of it to populate the fault level reported to the guest on failing
to translate a stage-1 walk.
- Add NV support to the GICv3-on-GICv5 emulation code, ensuring
feature parity for guests, irrespective of the host platform.
- Fix some really ugly architecture problems when dealing with debug
in a nested VM. This has some bad performance impacts, but is at
least correct.
- Add enough infrastructure to be able to disable EL2 features and
give effective values to the EL2 control registers. This then allows
a bunch of features to be turned off, which helps cross-host
migration.
- Large rework of the selftest infrastructure to allow most tests to
transparently run at EL2. This is the first step towards enabling
NV testing.
- Various fixes and improvements all over the map, including one BE
fix, just in time for the removal of the feature.

KVM/arm64 changes for 6.17, round #3
- Invalidate nested MMUs upon freeing the PGD to avoid WARNs when
visiting from an MMU notifier
- Fixes to the TLB match process and TLB invalidation range for
managing the VCNR pseudo-TLB
- Prevent SPE from erroneously profiling guests due to UNKNOWN reset
values in PMSCR_EL1
- Fix save/restore of host MDCR_EL2 to account for eagerly programming
at vcpu_load() on VHE systems
- Correct lock ordering when dealing with VGIC LPIs, avoiding scenarios
where an xarray's spinlock was nested with a *raw* spinlock
- Permit stage-2 read permission aborts which are possible in the case
of NV depending on the guest hypervisor's stage-2 translation
- Call raw_spin_unlock() instead of the internal spinlock API
- Fix parameter ordering when assigning VBAR_EL1

Pull workqueue updates from Tejun Heo:
- WQ_PERCPU was added to remaining alloc_workqueue() users and
system_wq usage was replaced with system_percpu_wq and
system_unbound_wq with system_dfl_wq.
These are equivalent conversions with no functional changes,
preparing for switching default to unbound workqueues from percpu.

Building perf with LIBBPF_DYNAMIC (ie not the default static linking of
libbpf with perf) is breaking as the libbpf isn't version 1.7 or newer,
where dont_enable is added to bpf_perf_event_opts.
To avoid this breakage add a compile time version check and don't
declare the variable when not present.
Fixes: 5e2ac8e8571df54d ("perf bpf-filter: Enable events manually")

Move the Data Path (DP)-specific fields from ath12k_vif into a new
structure ath12k_dp_vif, embedded within ath12k_vif. This new structure
contains an array of per-link DP fields represented by ath12k_dp_link_vif.
Since dp_link_vif is small and frequently accessed from ahvif during Tx,
it is stored as an array of structs rather than an array of pointers to
avoid additional indirections and improve cache efficiency. However,
this design comes with a trade-off: because the array is not pointer-based,
it increases memory usage.
Per packet data path makes use of ath12k_dp_vif and ath12k_dp_link_vif.
Add pdev_idx and lmac_id in ath12k_dp_link_vif to avoid accessing ar in
dp tx.
Diagrammatic view of the new structure is below:
+--------------------------------+

Currently, the DP service SRNG handler is invoked directly from the NAPI
poll handler, which prevents using different handlers for different
architectures. To fix this, introduce a DP architecture-ops table to
invoke architecture specific handler from NAPI poll handler. Future patches
will leverage this framework to invoke architecture-specific handlers from
common code.

Add arch_init() and arch_deinit() ops to the PCI and AHB family ops to
support allocation and cleanup of architecture-specific fields in
ath12k_base. Define shared ath12k_wifi7_arch_init() and
ath12k_wifi7_arch_deinit() functions to handle DP device allocation and
cleanup for Wi-Fi 7 across both PCI and AHB. Introduce a new header file
wifi7/core.h to declare functions defined in wifi7/core.c.
Currently, DP device allocation and cleanup are handled via arch_init()
and arch_deinit(), which can be extended to support additional
architecture-specific initialization in the future.
Define common ath12k_wifi7_arch_init() and

Add ath12k_dp_cmn_device_init() and ath12k_dp_cmn_device_deinit() to
initialize and deinitialize common DP device fields. Introduce a new header
file dp_cmn.h to declare these functions, which can also be used to expose
new common DP functions that need to be invoked from non-DP code.
Rename existing DP allocation and cleanup functions to ath12k_dp_setup()
and ath12k_dp_cleanup() to better reflect their purpose in the updated
design.
Replicate device-related fields such as device and hw_params in the DP
device object to align with the new design, which limits per packet data

Currently, the Data Path (DP) specific device object (ath12k_dp) is
embedded directly within the ath12k_base structure. The DP object cannot
be extended with architecture-specific fields within a contiguous memory
block with this design.
To address this, convert ath12k_dp into a dynamically allocated object
and store it as a pointer in ath12k_base. This change allows allocation
and initialization of ath12k_dp based on the underlying hardware
architecture. Architecture-specific fields can now be maintained as
private data within a contiguous memory block of ath12k_dp.
This patch (and the forthcoming patches) are intended to serve the purpose
of refactoring different DP objects for the Next Generation ath12k
driver.

Pull sched_ext updates from Tejun Heo:
- Code organization cleanup. Separate internal types and accessors to
ext_internal.h to reduce the size of ext.c and improve
maintainability.
- Prepare for cgroup sub-scheduler support by adding @sch parameter to
various functions and helpers, reorganizing scheduler instance
handling, and dropping obsolete helpers like scx_kf_exit() and
kf_cpu_valid().
- Add new scx_bpf_cpu_curr() and scx_bpf_locked_rq() BPF helpers to
provide safer access patterns with proper RCU protection.
scx_bpf_cpu_rq() is deprecated with warnings due to potential race
conditions.
- Improve debugging with migration-disabled counter in error state
dumps, SCX_EFLAG_INITIALIZED flag, bitfields for warning flags, and
other enhancements to help diagnose issues.
- Use cgroup_lock/unlock() for cgroup synchronization instead of
scx_cgroup_rwsem based synchronization. This is simpler and allows
enable/disable paths to synchronize against cgroup changes
independent of the CPU controller.
- rhashtable_lookup() replacement to avoid redundant RCU locking was
reverted due to RCU usage warnings. Will be redone once rhashtable is
updated to use rcu_dereference_all().
- Other misc updates and fixes including bypass handling improvements,
scx_task_iter_relock() improvements, tools/sched_ext updates, and

Pull lsm updates from Paul Moore:
- Move the management of the LSM BPF security blobs into the framework
In order to enable multiple LSMs we need to allocate and free the
various security blobs in the LSM framework and not the individual
LSMs as they would end up stepping all over each other.
- Leverage the lsm_bdev_alloc() helper in lsm_bdev_alloc()
Make better use of our existing helper functions to reduce some code
duplication.
- Update the Rust cred code to use 'sync::aref'
Part of a larger effort to move the Rust code over to the 'sync'
module.
- Make CONFIG_LSM dependent on CONFIG_SECURITY
As the CONFIG_LSM Kconfig setting is an ordered list of the LSMs to
enable a boot, it obviously doesn't make much sense to enable this
when CONFIG_SECURITY is disabled.
- Update the LSM and CREDENTIALS sections in MAINTAINERS with Rusty
bits
Add the Rust helper files to the associated LSM and CREDENTIALS
entries int the MAINTAINERS file. We're trying to improve the
communication between the two groups and making sure we're all aware
of what is going on via cross-posting to the relevant lists is a good

Update sel_read_bool() to use a four byte stack buffer instead of a
memory page fetched via get_zeroed_page(), and fix a memory in the
process.
Needless to say we should have done this a long time ago, but it was
in a very old chunk of code that "just worked" and I don't think
anyone had taken a real look at it in many years.

Pull btrfs updates from David Sterba:
"There are no new features, the changes are in the core code, notably
tree-log error handling and reporting improvements, and initial
support for block size > page size.
Performance improvements:
- search data checksums in the commit root (previous transaction) to
avoid locking contention, this improves parallelism of read
heavy/low write workloads, and also reduces transaction commit
time; on real and reproducer workload the sync time went from
minutes to tens of seconds (workload and numbers are in the
changelog)
Core:
- tree-log updates:
- error handling improvements, transaction aborts
- add new error state 'O' (printed in status messages) when log
replay fails and is aborted
- reduced number of btrfs_path allocations when traversing the
tree
- 'block size > page size' support
- basic implementation with limitations, under experimental build
- limitations: no direct io, raid56, encoded read (standalone and
in send ioctl), encoded write
- preparatory work for compression, removing implicit assumptions
of page and block sizes
- compression workspaces are now per-filesystem, we cannot assume
common block size for work memory among different filesystems
- tree-checker now verifies INODE_EXTREF item (which is implementing
hardlinks)
- tree leaf pretty printer updates, there were missing data from
items, keys/items
- move config option CONFIG_BTRFS_REF_VERIFY to CONFIG_BTRFS_DEBUG,
it's a debugging feature and not needed to be enabled separately
- more struct btrfs_path auto free updates
- use ref_tracker API for tracking delayed inodes, enabled by mount
option 'ref_verify', allowing to better pinpoint leaking references
- in zoned mode, avoid selecting data relocation zoned for ordinary
data block groups
