* SecurityPkg: Refine type cast for pointer subtractionHao Wu2017-03-061-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For pointer subtraction, the result is of type "ptrdiff_t". According to the C11 standard (Committee Draft - April 12, 2011): "When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. The size of the result is implementation-defined, and its type (a signed integer type) is ptrdiff_t defined in the <stddef.h> header. If the result is not representable in an object of that type, the behavior is undefined." In our codes, there are cases that the pointer subtraction is not performed by pointers to elements of the same array object. This might lead to potential issues, since the behavior is undefined according to C11 standard. Also, since the size of type "ptrdiff_t" is implementation-defined. Some static code checkers may warn that the pointer subtraction might underflow first and then being cast to a bigger size. For example: UINT8 *Ptr1, *Ptr2; UINTN PtrDiff; ... PtrDiff = (UINTN) (Ptr1 - Ptr2); The commit will refine the pointer subtraction expressions by casting each pointer to UINTN first and then perform the subtraction: PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2; Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Hao Wu <hao.a.wu@intel.com> Acked-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Chao Zhang <chao.b.zhang@intel.com>

* Move Smbios measurement from TCG driver to Smbios driver.Yao, Jiewen2015-10-272-36/+1
| | | | | | | | | | | | | | | | | | | This is patch to remove smbios measurement in TCG driver. There will be other patch to add it in Smbios driver. The problem of current SMBIOS measurement is: 1) TCG drivers do not support SMBIOS3.0 table. 2) TCG drivers do not follow TCG platform spec on: "Platform configuration information that is automatically updated, such as clock registers, and system unique information, such as asset numbers or serial numbers, MUST NOT be measured into PCR [1], or any other PCR." So we decide to move Smbios measurement from TCG drivers to Smbios driver.
