KVM: s390: Fixes for 7.0 - fix deadlock in new memory management - handle kernel faults on donated memory properly - fix bounds checking for irq routing + selftest - fix invalid machine checks + logging

KVM: s390: selftests: Add IRQ routing address offset tests

2026-03-16T15:56:39+00:00

This test tries to setup routes which have address + offset combinations which cross a page. Reviewed-by: Matthew Rosato Tested-by: Matthew Rosato Signed-off-by: Janosch Frank Signed-off-by: Christian Borntraeger

selftests: kvm: add a test that VMX validates controls on RSM

2026-03-11T17:41:12+00:00

Add a test checking that invalid eVMCS contents are validated after an RSM instruction is emulated. The failure mode is simply that the RSM succeeds, because KVM virtualizes NMIs anyway while running L2; the two pin-based execution controls used by the test are entirely handled by KVM and not by the processor.

KVM x86 APIC-ish changes for 6.20 - Fix a benign bug where KVM could use the wrong memslots (ignored SMM) when creating a vCPU-specific mapping of guest memory. - Clean up KVM's handling of marking mapped vCPU pages dirty. - Drop a pile of *ancient* sanity checks hidden behind in KVM's unused ASSERT() macro, most of which could be trivially triggered by the guest and/or user, and all of which were useless. - Fold "struct dest_map" into its sole user, "struct rtc_status", to make it more obvious what the weird parameter is used for, and to allow burying the RTC shenanigans behind CONFIG_KVM_IOAPIC=y. - Bury all of ioapic.h and KVM_IRQCHIP_KERNEL behind CONFIG_KVM_IOAPIC=y. - Add a regression test for recent APICv update fixes. - Rework KVM's handling of VMCS updates while L2 is active to temporarily switch to vmcs01 instead of deferring the update until the next nested VM-Exit. The deferred updates approach directly contributed to several bugs, was proving to be a maintenance burden due to the difficulty in auditing the correctness of deferred updates, and was polluting "struct nested_vmx" with a growing pile of booleans. - Handle "hardware APIC ISR", a.k.a. SVI, updates in kvm_apic_update_apicv() to consolidate the updates, and to co-locate SVI updates with the updates for KVM's own cache of ISR information. - Drop a dead function declaration.

KVM SVM changes for 6.20 - Drop a user-triggerable WARN on nested_svm_load_cr3() failure. - Add support for virtualizing ERAPS. Note, correct virtualization of ERAPS relies on an upcoming, publicly announced change in the APM to reduce the set of conditions where hardware (i.e. KVM) *must* flush the RAP. - Ignore nSVM intercepts for instructions that are not supported according to L1's virtual CPU model. - Add support for expedited writes to the fast MMIO bus, a la VMX's fastpath for EPT Misconfig. - Don't set GIF when clearing EFER.SVME, as GIF exists independently of SVM, and allow userspace to restore nested state with GIF=0. - Treat exit_code as an unsigned 64-bit value through all of KVM. - Add support for fetching SNP certificates from userspace. - Fix a bug where KVM would use vmcb02 instead of vmcb01 when emulating VMLOAD or VMSAVE on behalf of L2. - Misc fixes and cleanups.

KVM selftests changes for 6.20 - Add a regression test for TPR<=>CR8 synchronization and IRQ masking. - Overhaul selftest's MMU infrastructure to genericize stage-2 MMU support, and extend x86's infrastructure to support EPT and NPT (for L2 guests). - Extend several nested VMX tests to also cover nested SVM. - Add a selftest for nested VMLOAD/VMSAVE. - Rework the nested dirty log test, originally added as a regression test for PML where KVM logged L2 GPAs instead of L1 GPAs, to improve test coverage and to hopefully make the test easier to understand and maintain.

KVM/arm64 updates for 7.0 - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes.
