When 'injecting' an edge-triggered interrupt with a falling edge we shouldn't clear the pending state on the distributor. In fact, we don't, because the check in vgic_validate_injection would prevent us from ever reaching this bit of code. Remove the unreachable snippet.

Currently we mangle the endianness of the guest's register even on an MMIO _read_, where it is completely useless, because we will not use the value of that register. Rework the io_mem_abort() function to clearly separate between reads and writes and only do the endianness mangling on MMIO writes.

Readonly memslots are often used to implement emulation of ROMs and NOR flashes, in which case the guest may legally map these regions as uncached. To deal with the incoherency associated with uncached guest mappings, treat all readonly memslots as incoherent, and ensure that pages that belong to regions tagged as such are flushed to DRAM before being passed to the guest.

This reverts commit 85c8555f ("KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn. The problem being addressed by the patch above was that some ARM code based the memory mapping attributes of a pfn on the return value of kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should be mapped as device memory. However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin, and the existing non-ARM users were already using it in a way which suggests that its name should probably have been 'kvm_is_reserved_pfn' from the beginning, e.g., whether or not to call get_page/put_page on it etc. This means that returning false for the zero page is a mistake and the patch above should be reverted.

In order to access the shadow VMCS, we need to load it. At this point, vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If we now get preempted by Linux, vmx_vcpu_put and, on return, the vmx_vcpu_load will work against the wrong vmcs. That can cause copy_shadow_to_vmcs12 to corrupt the vmcs12 state. Fix the issue by disabling preemption during the copy operation. copy_vmcs12_to_shadow is safe from this issue as it is executed by vmx_vcpu_run when preemption is already disabled before vmentry. This bug is exposed by running Jailhouse within KVM on CPUs with shadow VMCS support. Jailhouse never expects an interrupt pending vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12 is preempted, the active VMCS happens to have the virtual interrupt pending flag set in the CPU-based execution controls.

Commit d1442d85 ("KVM: x86: Handle errors when RIP is set during far jumps") introduced a bug that caused the fix to be incomplete. Due to incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may not trigger #GP. As we know, this imposes a security problem. In addition, the condition for two warnings was incorrect.

由 Paolo Bonzini 提交于
Emulation of code that is 14 bytes to the segment limit or closer (e.g. RIP = 0xFFFFFFF2 after reset) is broken because we try to read as many as 15 bytes from the beginning of the instruction, and __linearize fails when the passed (address, size) pair reaches out of the segment. To fix this, let __linearize return the maximum accessible size (clamped to 2^32-1) for usage in __do_insn_fetch_bytes, and avoid the limit check by passing zero for the desired size. For expand-down segments, __linearize is performing a redundant check. (u32)(addr.ea + size - 1) <= lim can only happen if addr.ea is close to 4GB; in this case, addr.ea + size - 1 will also fail the check against the upper bound of the segment (which is provided by the D/B bit). After eliminating the redundant check, it is simple to compute the *max_size for expand-down segments too. Now that the limit check is done in __do_insn_fetch_bytes, we want to inject a general protection fault there if size < op_size (like __linearize would have done), instead of just aborting. This fixes booting Tiano Core from emulated flash with EPT disabled.

The error code for #GP and #SS is zero when the segment is used to access an operand or an instruction. It is only non-zero when a segment register is being loaded; for limit checks this means cases such as: * for #GP, when RIP is beyond the limit on a far call (before the first instruction is executed). We do not implement this check, but it would be in em_jmp_far/em_call_far. * for #SS, if the new stack overflows during an inter-privilege-level call to a non-conforming code segment. We do not implement stack switching at all. So use an error code of zero. Reviewed-by: NNadav Amit <namit@cs.technion.ac.il> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>
