REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1193 This commit will add a new BaseLib API AsmLfence(). This API will perform a serializing operation on all load-from-memory instructions that were issued prior to the call of this function. Please note that this API is only available on IA-32 and x64. The purpose of adding this API is to mitigate of the [CVE-2017-5753] Bounds Check Bypass issue when untrusted data are being processed within SMM. More details can be referred at the 'Bounds check bypass mitigation' section at the below link: https://software.intel.com/security-software-guidance/insights/host-firmware-speculative-execution-side-channel-mitigation Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Leif Lindholm <leif.lindholm@linaro.org> Cc: Michael D Kinney <michael.d.kinney@intel.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Hao Wu <hao.a.wu@intel.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com> Acked-by: Laszlo Ersek <lersek@redhat.com> Regression-tested-by: Laszlo Ersek <lersek@redhat.com> |
