commit e39ff386f626ba44f8a9a9608d8f5f13ff7945ef Author: Jan Beulich <jbeulich@xxxxxxxx> Date: Thu Jun 28 11:23:33 2018 +0200 x86/HVM: don't cause #NM to be raised in Xen The changes for XSA-267 did not touch management of CR0.TS for HVM guests. In fully eager mode this bit should never be set when respective vCPU-s are active, or else hvmemul_get_fpu() might leave it wrongly set, leading to #NM in hypervisor context. {svm,vmx}_enter() and {svm,vmx}_fpu_dirty_intercept() become unreachable this way. Explicit {svm,vmx}_fpu_leave() invocations need to be guarded now. With no CR0.TS management necessary in fully eager mode, there's also no need anymore to intercept #NM.

Restore the readonly= parameter to SCSI disks. For IDE disks this is supposed to be rejected; add an assert. And there is a bare ad-hoc disk drive string in libxl__build_device_model_args_new, which we also update. This is XSA-266.

While a General Detect #DB exception does have fault semantics, hardware clears %dr7.gd on entry to the handler, meaning that it is actually safe to return to. Furthermore, %dr6.gd is guest controlled and sticky (never cleared by hardware). A malicious PV guest can therefore trigger the fatal_trap() and crash Xen. Instruction breakpoints are more tricky. The breakpoint match bits in %dr6 are not sticky, but the Intel manual warns that they may be set for non-enabled breakpoints, so add a breakpoint enabled check. Beyond that, because of the restriction on the linear addresses PV guests can set, and the fault (rather than trap) nature of instruction breakpoints (i.e. can't be deferred by a MovSS shadow), there should be no way to encounter an instruction breakpoint in Xen context. However, for extra robustness, deal with this situation by clearing the breakpoint configuration, rather than crashing.

Instead of adding a 3rd invocation of stts() to vcpu_restore_fpu_eager(), consolidate all of them into a single one done at the end of the function. Rename the function at the same time to better reflect its purpose, as the patches touches all of its occurences anyway. The new function parameter is not really well named, but "need_stts_if_not_fully_eager" seemed excessive to me.

First, the nonlazy xstates were never restored after returning from the runtime call. Secondly, with the fully_eager_fpu mitigation for XSA-267 / LazyFPU, the unilateral stts() is no longer correct, and hits an assertion later when a lazy state restore tries to occur for a fully eager vcpu. Fix both of these issues by calling vcpu_restore_fpu_eager(). As EFI runtime services can be used in the idle context, the idle assertion needs to move until after the fully_eager_fpu check. Introduce a "curr" local variable and replace other uses of "current" at the same time.
