<andrew.cooper3@xxxxxxxxxx> Date: Mon Oct 19 15:51:22 2020 +0100 x86/pv: Flush TLB in response to paging structure changes With MMU_UPDATE, a PV guest can make changes to higher level pagetables. This is safe from Xen's point of view (as the update only affects guest mappings), and the guest is required to flush (if necessary) after making updates. However, Xen's use of linear pagetables (UPDATE_VA_MAPPING, GNTTABOP_map, writeable pagetables, etc.) is an implementation detail outside of the API/ABI. Changes in the paging structure require invalidations in the linear pagetable range for subsequent accesses into the linear pagetables to access non-stale mappings. Xen must provide suitable flushing to prevent intermixed guest actions from accidentally accessing/modifying the wrong pagetable. For all L2 and higher modifications, flush the TLB. PV guests cannot create L2 or higher entries with the Global bit set, so no mappings established in the linear range can be global. (This could in principle be an order 39 flush starting at LINEAR_PT_VIRT_START, but no such mechanism exists in practice.) Express the necessary flushes as a set of booleans which accumulate across the operation. Comment the flushing logic extensively. This is XSA-286.

However, this was unnecessary. It is the guests responsibility to perform appropriate TLB flushing if the L4 modification altered an established mapping in a flush-relevant way. In this case, an MMUEXT_OP hypercall will follow. The case which Xen needs to cover is when new mappings are created, and the resync on the exit-to-guest path covers this correctly. There is a corner case with multiple vCPUs in hypercalls at the same time, which 9d1d31ad9498 changed, and this patch changes back to its original XPTI behaviour. Architecturally, established TLB entries can continue to be used until the broadcast flush has completed. Therefore, even with concurrent hypercalls, the guest cannot depend on older mappings not being used until an MMUEXT_OP hypercall completes. Xen's implementation of guest-initiated flushes will take correct effect on top of an in-progress hypercall, picking up new mapping setting before the other vCPU's MMUEXT_OP completes. Note: The correctness of this change is not impacted by whether XPTI uses global mappings or not. Correctness there depends on the behaviour of Xen on the entry/exit paths when switching two/from the XPTI "shadow" pagetables. This is (not really) XSA-286 (but necessary to simplify the logic).
