2015-07-13MdePkg: ensure SafeString length functions don't access beyond MaxSizeLeif Lindholm
The StrnLenS and AsciiStrnLenS functions, when presented with a string with no terminating NULL in the first MaxSize characters will check the character at String[MaxSize] before checking if Length < MaxSize. (They return the correct value, but have accessed beyond the stated limit in the process.) Flip the order of the tests to prevent this behaviour.

2015-04-30MdePkg/BaseLib: Preserve EBX register and fix stack offset to LinearAddress ↵Michael Kinney
in AsmFlushCacheLine() The value of EBX must be preserved to follow IA32 cdecl calling convention in the assembly implementation of AsmFlushCacheLine(). The CPUID instruction modifies the EBX register. The EBX register value is saved onto the stack before CPUID and restored from the stack after CPUID. The update to the inline assembly implementation of AsmFlushCacheLine() changed the location of the LinearAddress parameter value on the stack. The hardcoded lookup using [esp + 4] is not correct. Use the parameter name LinearAddress instead of the hard coded [esp + 4] stack location to prevent this issue from occurring again if there are changes to the inline assembly in the future.

2015-03-27MdePkg: fix ARM version of InternalMathSwapBytes64 ()Ard Biesheuvel
The ARM asm implementation of InternalMathSwapBytes64 () does interesting things if bit 7 of operand r1 (upper 32 bits of the input value) is set. After the recursive swap, bit 7 ends up in the sign bit position, after which it is right shifted with sign extension, and or'ed with the upper half of the output value. This means SwapBytes64 (0x00000080_00000000) returns an incorrect value of 0xFFFFFFFF_80000000.

2011-11-08MdePkg/BaseLib: Replaced inline assembly for ARMGCC by GCC assembly source fileoliviermartin
The registers used to passed arguments to the DxeCore entrypoint in the inline assembly function InternalSwitchStackAsm() where switched at compilation time. This change replaces the inline assembly by a pure assembly source file to avoid this kind of optimization. Note: Inline assembly is generally not recommanded in system programming.
