- Invalidate the ITS translation cache when the guest changes the
base address of the ITS tables (Fuad Tabba)
- Skip saving ITS devices with device IDs that are out-of-bounds
rather than failing the entire ITS save ioctl (Fuad Tabba)
- Close race between VM teardown and invalidations of nested MMUs
when handling MMU operations that are allowed to block
(Lorenzo Stoakes)
- Various fixes for the handling of the host's untrusted SVE
configuration in pKVM (Fuad Tabba)
- Make sure that empty SMCCC ranges based at 0 are rejected by the
kvm_smccc_set_filter() (Karl Mehltretter)
- Revoke the host mapping for pKVM's private stack pages, along
with a new sanity check that all mappings in the hyp's private
VA range have been correctly marked as hyp-owned (Fuad Tabba)
- Lifetime fixes for the array of shadow stage-2 MMUs, ensuring that
concurrent vCPU initialization cannot relocate in-use MMUs. Defer
the freeing of shadow stage-2 MMUs to the point that no other users
(e.g. MMU notifier) could reference them (Marc Zyngier)
- Drop useless WARN when rejecting an unsupported ioctl for pKVM
(Fuad Tabba)
- Fix the steal_time selftest to install correctly-sized mappings for
non-4K hosts (Sebastian Ott)
- Correct mapping of fine-grained trap for GCSPOPX instruction
(Mark Brown)
- Fix KVM_BUG_ON() due to missing handling of DBGBXVR<n> from 32-bit
guests (Karl Mehltretter)
RISC-V:
- Synchronize hrtimer during VCPU teardown.
- Fix the conversion between vsip and hvip values.
- Serialize IMSIC attributes with vCPU migration.
- Release unused page after MMU invalidation.
- Propagate interrupted G-stage faults to KVM user-space as EINTR.
- Fix nested acceleration hfence entry update order.
- Fix sdata leak and stale snapshot_addr in snapshot_set_shmem.
- Preserve firmware counter value across PMU counter stop/start.
- Report PMU snapshot write failure to the guest.
- Fix perf-backed counter accounting across PMU stop and read.
- Correctly propagate error of a hart status SBI call.
s390:
- Ensure that accesses through kvm_arch_set_irq_inatomic mark as dirty
the pages that contain indicator and summary bits.
- Fix compile warning for kvm_s390_update_cmma_dirty().
- Fix incorrect propagation of ENOENT from _gaccess_shadow_fault() to
userspace.
- Move s390_kvm_mmu_commit_memory_region() into
s390_kvm_mmu_prepare_memory_region() so that it can fail instead of WARN.
- Add missing srcu in kvm_s390_set_irq_state().
- Fix potential races in storage functions.
- Fix race in _destroy_pages_crste().
- Fix issues in the handling of KVM interrupt and page resources, when a
queue that is assigned to a mediated device (mdev) is removed from the
host's AP configuration.
- Fix loop condition in uv_find_secrets.
- Prevent potential out-of-bounds read.
x86:
- Fix a brown paper bag bug where KVM would incorrectly treat Intel PMU MSRs
as valid on AMD.
- Fix a regression in the hardware disable selftest where it checked the wrong
macro when detecting glibc support (breaks at least musl).
- Never clear KVM_REQ_VM_DEAD so that dead VMs stay dead, which is especially
important for KVM_BUG_ON() flows, which often guard more dangerous bugs.
- Re-pend GET_NESTED_STATE_PAGES if getting the pages fails, to fix a bug
where KVM would let userspace run a broken setup with stale vmcs12 pages.
- Fix a class of bugs where KVM would fail to fill kvm_run exit fields if
getting nested pages failed.
- Treat reserved entries in the memory attributes xarray as "no attributes",
to fix false positives when checking for mixed attributes.
- Fix memcg accounting for the memory attributes xarray (the xarray library
subtly requires the xarray to be configured for accounting upfront; the gfp
flags taken at runtime are used only rarely).
- Don't pre-reserve xarray entries when storing empty attributes, as storing
NULL must not require memory allocation (KVM and other subsystems heavily
rely on this behavior).
- Fix a memory leak and a cache maintenance issue related to doing intra-host
migration on an SEV guest.
