This small series evolved from a single vCPU ID limit check to multiple ones, including sanity checks among them and enhanced selftests. Please apply! Thanks, Mathias v2: https://lore.kernel.org/kvm/20240612215415.3450952-1-minipli@xxxxxxxxxxxxxx/ changes v2->v3: - test max_vcpu_ids on bsp_vcpu_id limit check if already set (Sean) - add patch to check max_vcpu_ids to not exclude bsp_vcpu_id (Sean) - reorder series to have selftests at the end - minor commit log cosmetics changes v1->v2: - add comment and build bug to make truncation check more obvious (Sean) - handle KVM_SET_BOOT_CPU_ID similar Mathias Krause (4): KVM: Reject overly excessive IDs in KVM_CREATE_VCPU KVM: x86: Limit check IDs for KVM_SET_BOOT_CPU_ID KVM: selftests: Test max vCPU IDs corner cases KVM: selftests: Test vCPU boot IDs above 2^32 Sean Christopherson (1): KVM: x86: Prevent excluding the BSP on setting max_vcpu_ids arch/x86/kvm/x86.c | 7 +++++- .../kvm/x86_64/max_vcpuid_cap_test.c | 22 +++++++++++++++++-- .../selftests/kvm/x86_64/set_boot_cpu_id.c | 11 ++++++++++ virt/kvm/kvm_main.c | 10 ++++++++- 4 files changed, 46 insertions(+), 4 deletions(-) -- 2.30.2
