| * KVM: VMX: Update instruction length on intercepted BPJan Kiszka2010-03-011-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | We intercept #BP while in guest debugging mode. As VM exits due to intercepted exceptions do not necessarily come with valid idt_vectoring, we have to update event_exit_inst_len explicitly in such cases. At least in the absence of migration, this ensures that re-injections of #BP will find and use the correct instruction length.

| * KVM: Fix emulate_sys[call, enter, exit]()'s fault handlingTakuya Yoshikawa2010-03-011-17/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes emulate_syscall(), emulate_sysenter() and emulate_sysexit() to handle injected faults properly. Even though original code injects faults in these functions, we cannot handle these unless we use the different return value from the UNHANDLEABLE case. So this patch use X86EMUL_* codes instead of -1 and 0 and makes x86_emulate_insn() to handle these propagated faults. Be sure that, in x86_emulate_insn(), goto cannot_emulate and goto done with rc equals X86EMUL_UNHANDLEABLE have same effect.

| * KVM: Fix load_guest_segment_descriptor() to inject page faultTakuya Yoshikawa2010-03-011-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch injects page fault when reading descriptor in load_guest_segment_descriptor() fails with FAULT. Effects of this injection: This function is used by kvm_load_segment_descriptor() which is necessary for the following instructions: - mov seg,r/m16 - jmp far - pop ?s This patch makes it possible to emulate the page faults generated by these instructions. But be sure that unless we change the kvm_load_segment_descriptor()'s ret value propagation this patch has no effect.

| * KVM: VMX: emulate accessed bit for EPTRik van Riel2010-03-011-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently KVM pretends that pages with EPT mappings never got accessed. This has some side effects in the VM, like swapping out actively used guest pages and needlessly breaking up actively used hugepages. We can avoid those very costly side effects by emulating the accessed bit for EPT PTEs, which should only be slightly costly because pages pass through page_referenced infrequently. TLB flushing is taken care of by kvm_mmu_notifier_clear_flush_young(). This seems to help prevent KVM guests from being swapped out when they should not on my system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes kvm_fix_hypercall() to propagate X86EMUL_* info generated by emulator_write_emulated() to its callers: suggested by Marcelo. The effect of this is x86_emulate_insn() will begin to handle the page faults which occur in emulator_write_emulated(): this should be OK because emulator_write_emulated_onepage() always injects page fault when emulator_write_emulated() returns X86EMUL_PROPAGATE_FAULT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes load_guest_segment_descriptor() to return X86EMUL_PROPAGATE_FAULT when it tries to access the descriptor table beyond the limit of it: suggested by Marcelo. I have checked current callers of this helper function, - kvm_load_segment_descriptor() - kvm_task_switch() and confirmed that this patch will change nothing in the upper layers if we do not change the handling of this return value from load_guest_segment_descriptor(). Next step: Although fixing the kvm_task_switch() to handle the propagated faults properly seems difficult, and maybe not worth it because TSS is not used commonly these days, we can fix kvm_load_segment_descriptor(). By doing so, the injected #GP becomes possible to be handled by the guest. The only problem for this is how to differentiate this fault from the page faults generated by kvm_read_guest_virt(). We may have to split this function to achive this goal. Signed-off-by: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
