------------------------------------------------------------ commit 4597fc97b3b8870c39214e3aa4132ab711a40691 Author: Julien Grall <jgrall@xxxxxxxxxx> Date: Tue Jul 7 15:43:59 2020 +0200 xen: Check the alignment of the offset pased via VCPUOP_register_vcpu_info Currently a guest is able to register any guest physical address to use for the vcpu_info structure as long as the structure can fits in the rest of the frame. This means a guest can provide an address that is not aligned to the natural alignment of the structure. On Arm 32-bit, unaligned access are completely forbidden by the hypervisor. This will result to a data abort which is fatal. On Arm 64-bit, unaligned access are only forbidden when used for atomic access. As the structure contains fields (such as evtchn_pending_self) that are updated using atomic operations, any unaligned access will be fatal as well. While the misalignment is only fatal on Arm, a generic check is added as an x86 guest shouldn't sensibly pass an unaligned address (this would result to a split lock). This is XSA-327.

In order to achieve this make sure data is written back to memory after writing an EPT entry when the recalc bit is not set in atomic_write_ept_entry. If such bit is set, the entry will be adjusted and atomic_write_ept_entry will be called a second time without the recalc bit set. Note that when splitting a super page the new tables resulting of the split should also be written back. Failure to do so can allow devices behind the IOMMU access to the stale super page, or cause coherency issues as changes made by the processor to the page tables are not visible to the IOMMU. This allows to remove the VT-d specific iommu_pte_flush helper, since the cache write back is now performed by atomic_write_ept_entry, and hence iommu_iotlb_flush can be used to flush the IOMMU TLB. The newly used method (iommu_iotlb_flush) can result in less flushes, since it might sometimes be called rightly with 0 flags, in which case it becomes a no-op. This is part of XSA-321.

The new hook is added so that the cache can be flushed by code outside of VT-d when using shared page tables.
