2025-03-14KVM: arm64: Create each pKVM hyp vcpu after its corresponding host vcpuFuad Tabba
Instead of creating and initializing _all_ hyp vcpus in pKVM when the first host vcpu runs for the first time, initialize _each_ hyp vcpu in conjunction with its corresponding host vcpu. Some of the host vcpu state (e.g., system registers and traps values) is not initialized until the first time the host vcpu is run. Therefore, initializing a hyp vcpu before its corresponding host vcpu has run for the first time might not view the complete host state of these vcpus. Additionally, this behavior is inline with non-protected modes.

KVM_CAP_SYNC_REGS does not make sense for VMs with protected guest state, since the register values cannot actually be written. Return 0 when using the VM-level KVM_CHECK_EXTENSION ioctl, and accordingly return -EINVAL from KVM_RUN if the valid/dirty fields are nonzero. However, on exit from KVM_RUN userspace could have placed a nonzero value into kvm_run->kvm_valid_regs, so check guest_state_protected again and skip store_regs() in that case.

2025-03-14KVM: x86: Add infrastructure for secure TSCIsaku Yamahata
Add guest_tsc_protected member to struct kvm_arch_vcpu and prohibit changing TSC offset/multiplier when guest_tsc_protected is true. X86 confidential computing technology defines protected guest TSC so that the VMM can't change the TSC offset/multiplier once vCPU is initialized. SEV-SNP defines Secure TSC as optional, whereas TDX mandates it. KVM has common logic on x86 that tries to guess or adjust TSC offset/multiplier for better guest TSC and TSC interrupt latency at KVM vCPU creation (kvm_arch_vcpu_postcreate()), vCPU migration over pCPU (kvm_arch_vcpu_load()), vCPU TSC device attributes (kvm_arch_tsc_set_attr()) and guest/host writing to TSC or TSC adjust MSR (kvm_set_msr_common()). The current x86 KVM implementation conflicts with protected TSC because the VMM can't change the TSC offset/multiplier. Because KVM emulates the TSC timer or the TSC deadline timer with the TSC offset/multiplier, the TSC timer interrupts is injected to the guest at the wrong time if the KVM TSC offset is different from what the TDX module determined. Originally this issue was found by cyclic test of rt-test [1] as the latency in TDX case is worse than VMX value + TDX SEAMCALL overhead. It turned out that the KVM TSC offset is different from what the TDX module determines. Disable or ignore the KVM logic to change/adjust the TSC offset/multiplier somehow, thus keeping the KVM TSC offset/multiplier the same as the value of the TDX module. Writes to MSR_IA32_TSC are also blocked as they amount to a change in the TSC offset.

2025-03-14tracing: Correct the refcount if the hist/hist_debug file fails to openTengda Wu
The function event_{hist,hist_debug}_open() maintains the refcount of 'file->tr' and 'file' through tracing_open_file_tr(). However, it does not roll back these counts on subsequent failure paths, resulting in a refcount leak. A very obvious case is that if the hist/hist_debug file belongs to a specific instance, the refcount leak will prevent the deletion of that instance, as it relies on the condition 'tr->ref == 1' within __remove_instance(). Fix this by calling tracing_release_file_tr() on all failure paths in event_{hist,hist_debug}_open() to correct the refcount.

2025-03-13x86/vmware: Parse MP tables for SEV-SNP enabled guests under VMware hypervisorsAjay Kaher
Under VMware hypervisors, SEV-SNP enabled VMs are fundamentally able to boot without UEFI, but this regressed a year ago due to: 0f4a1e80989a ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests") In this case, mpparse_find_mptable() has to be called to parse MP tables which contains the necessary boot information.

2025-03-13Revert "fsnotify: generate pre-content permission event on page fault"Amir Goldstein
This reverts commit 8392bc2ff8c8bf7c4c5e6dfa71ccd893a3c046f6. In the use case of buffered write whose input buffer is mmapped file on a filesystem with a pre-content mark, the prefaulting of the buffer can happen under the filesystem freeze protection (obtained in vfs_write()) which breaks assumptions of pre-content hook and introduces potential deadlock of HSM handler in userspace with filesystem freezing. Now that we have pre-content hooks at file mmap() time, disable the pre-content event hooks on page fault to avoid the potential deadlock.
