Another day, another CPL patch... It turns out that the simple approach of getting CPL from SS.DPL broke x86/taskswitch2.flat. To fix that, already "imagine" that the CPL is CS.RPL, or 3 for VM86 tasks, while loading segment descriptors during task switches. This removes the hack where task switches call kvm_set_rflags to override the VM flag (patch 2). While at it, add a new privilege test during task switches that is missing. Patch 4 is the same as before. Paolo Bonzini (4): KVM: x86: use new CS.RPL as CPL during task switch KVM: x86: drop set_rflags callback KVM: x86: check CS.DPL against RPL during task switch KVM: x86: get CPL from SS.DPL arch/x86/include/asm/kvm_emulate.h | 1 - arch/x86/include/asm/kvm_host.h | 1 - arch/x86/kvm/emulate.c | 63 ++++++++++++++++++++++---------------- arch/x86/kvm/svm.c | 35 +++++++++------------ arch/x86/kvm/vmx.c | 24 +++------------ arch/x86/kvm/x86.c | 6 ---- 6 files changed, 54 insertions(+), 76 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
