2023-04-21RISC-V: KVM: Use bitmap for irqs_pending and irqs_pending_maskAnup Patel
To support 64 VCPU local interrupts on RV32 host, we should use bitmap for irqs_pending and irqs_pending_mask in struct kvm_vcpu_arch. Signed-off-by: Anup Patel <apatel@ventanamicro.com> Reviewed-by: Andrew Jones <ajones@ventanamicro.com> Signed-off-by: Anup Patel <anup@brainfault.org>

2023-04-21RISC-V: KVM: Drop the _MASK suffix from hgatp.VMID mask definesAnup Patel
The hgatp.VMID mask defines are used before shifting when extracting VMID value from hgatp CSR value so based on the convention followed in the other parts of asm/csr.h, the hgatp.VMID mask defines should not have a _MASK suffix. While we are here, let's use GENMASK() for hgatp.VMID and hgatp.PPN.

2023-04-21KVM: RISC-V: Retry fault if vma_lookup() results become invalidDavid Matlack
Read mmu_invalidate_seq before dropping the mmap_lock so that KVM can detect if the results of vma_lookup() (e.g. vma_shift) become stale before it acquires kvm->mmu_lock. This fixes a theoretical bug where a VMA could be changed by userspace after vma_lookup() and before KVM reads the mmu_invalidate_seq, causing KVM to install page table entries based on a (possibly) no-longer-valid vma_shift. Re-order the MMU cache top-up to earlier in user_mem_abort() so that it is not done after KVM has read mmu_invalidate_seq (i.e. so as to avoid inducing spurious fault retries). It's unlikely that any sane userspace currently modifies VMAs in such a way as to trigger this race. And even with directed testing I was unable to reproduce it. But a sufficiently motivated host userspace might be able to exploit this race. Note KVM/ARM had the same bug and was fixed in a separate, near identical patch (see Link).
