Hao Wu ea0b15067c MdePkg/PrintLib: Fix possible negative value left shift
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=702

Within function InternalPrintLibSPrintMarker(), possible left shift of a
negative value is found in:
"(*(ArgumentString + 1) << 8)"

which involves undefined behavior.

Since '*(ArgumentString + 1)' is of type CONST CHAR8 (signed), it will be
promoted to type int (signed) during the left shift operation. If
'*(ArgumentString + 1)' is a negative value, the behavior will be
undefined.

According to the C11 spec, Section 6.5.7:
> 4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated
>   bits are filled with zeros. If E1 has an unsigned type, the value
>   of the result is E1 * 2^E2 , reduced modulo one more than the
>   maximum value representable in the result type. If E1 has a signed
>   type and nonnegative value, and E1 * 2^E2 is representable in the
>   result type, then that is the resulting value; otherwise, the
>   behavior is undefined.

This commit explicitly cast '*(ArgumentString + 1)' with UINT8 to resolve
this issue.

Hao Wu 9fdf31789a MdePkg/BaseLib: Avoid reading content beyond string boundary
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=705

As mentioned in the above Bugzilla link by Steven, within the function
PathCleanUpDirectories(), when executing command:
"cd ."

under Shell, the input parameter 'Path' string will have string length
less than 2. Hence, it is possible for the below statement:
"if (StrCmp (Path + StrLen (Path) - 2, L"\\.") == 0) {"

to read contents before the string boundary.

This commit adds additional checks to avoid this.

Laszlo Ersek 98a4d04e8f MdePkg/BaseIoLibIntrinsic: fix SEV (=unrolled) variants of IoWriteFifoXX()
In commit b6d11d7c46 ("MdePkg: BaseIoLibIntrinsic (IoLib class)
library", 2017-04-12), the MOV instructions in the write loops were
probably copied from the read loops. However, the operand order was not
adjusted.

As a result, the IoWriteFifoXX() routines, when invoked in SEV guests, now
overwrite the source buffer with value 0x01 / 0x0001 / 0x00000001 -- the
SevNoRepIo() function returns value 1 in EAX, in SEV guests --, and write
the same value to the target IO port.

Fix this by putting the target operand (AL / AX / EAX) first, and the
source operand (BYTE / WORD / DWORD [ESI/RSI]) second.

Marvin.Haeuser@outlook.com 9062381a8c MdePkg/BaseLib: Update internal LinkedList verifications.
1) Replace InternalBaseLibIsNodeInList() with
   InternalBaseLibIsListValid().
   - The verification whether Node is within the doubly-linked List
     is now done by IsNodeInList().
   - Whether the list is valid is returned.

2) The comments within InsertHeadList() and InsertTailList() stated
   that it is checked whether Entry is not part of the doubly-linked
   list. This was not done as argument 3 of
   InternalBaseLibIsNodeInList() indicated whether the check is done,
   not whether to check if the node is or is not in the list. This
   has been fixed by using IsNodeInList() for the ASSERTs.

V2:
  - Fix IsListEmpty() to ASSERT when the passed list is invalid.
  - Introduce the VERIFY_IS_NODE_IN_LIST() macro to only verify whether the
    passed node is part of the list when PcdVerifyNodeInList is TRUE.

V3:
  - Introduce the ASSERT_VERIFY_NODE_IN_VALID_LIST() macro which,
    depending on the value of PcdVerifyNodeInList, verifies whether
    SecondEntry is or is not part of the same doubly-linked list as
    FirstEntry and unconditionally verifies whether the doubly-linked
    list FirstEntry is part of is valid. This prevents
    InternalBaseLibIsListValid() from being called twice when a
    function ASSERTs via the result of IsNodeInList(), as it calls
    InternalBaseLibIsListValid() already.
  - Remove the VERIFY_IS_NODE_IN_LIST() macro in favor of
    ASSERT_VERIFY_NODE_IN_VALID_LIST().

In function BasePrintLibSPrintMarker(), when processing ASCII format
strings, if the format string walker pointer 'Format' is pointing at the

*(Format + 1)

Though this value won't affect the functionality, since it will be masked
by variable 'FormatMask':
(*(Format + 1) << 8)) & FormatMask
(FormatMask is 0xff for ASCII format string)

This commit adds additional logic to avoid reading undefined content.

The commit adds check in function InternalPrintGraphic() to ensure that

The commit also adds an explicit UINT32 type cast for 'Blt->Width' to
avoid possible overflow in the int range for:

Blt->Width * Blt->Height

Since both Blt->Width and Blt->Height are of type UINT16. They will be
promoted to int (signed) first, and then perform the multiplication
operation. If the result of multiplication between Blt->Width and
Blt->Height exceeds the range of type int, a potential incorrect size will
be passed into function AllocateZeroPool().

  NewDevicePath = AppendDevicePathNode (DevicePath, DeviceNode);
  FreePool (DevicePath);
  FreePool (DeviceNode);
  DevicePath = NewDevicePath;
}
{code}
causes a problem. The END node that's appended it the node for the
entire list. So when the node is appended in AppendDevicePathNode,
it winds up disappearing. This leads to the path
'PciRoot(0x0),PciRoot(0x0)' parsing as if 'PciRoot(0x0)/PciRoot(0x0)'
were specified. These are two very different things.

Hao Wu 95ba3d92dc MdePkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Hao Wu 51f0ceb4eb MdePkg/BasePrintLib: Add safe print functions [A|U]ValueToStringS
Add the following 2 APIs:
UnicodeValueToStringS
AsciiValueToStringS

These safe version APIs are used to enhance their counterpart (APIs
without trailing 'S' in function names).

They perform checks to the input parameters and will return relative
status to reflect the check result.

Return RETURN_INVALID_PARAMETER when:
1). The input Buffer is NULL.
2). The input BufferSize is greater than (PcdMaximumUnicodeStringLength *
sizeof (CHAR16) + 1) for UnicodeValueToStringS or greater than
PcdMaximumAsciiStringLength for AsciiValueToStringS.
3). The input Flags is not set properly.
4). The input Width is not smaller than MAXIMUM_VALUE_CHARACTERS.

Return RETURN_BUFFER_TOO_SMALL when:
1). The input BufferSize cannot hold the converted value.

UnicodeBSPrintAsciiFormat
UnicodeSPrintAsciiFormat
AsciiVSPrint
AsciiBSPrint

They will ASSERT when:
1) The input parameter 'StartOfBuffer' is NULL if 'BufferSize' indicates
at least 1 Ascii/Unicode character can be held.
2) The input parameter 'FormatString' is NULL if 'BufferSize' indicates at
least 1 Ascii/Unicode character can be held.
3) The input parameter 'FormatString' contains more than
PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters.
4) The produced string contains more than
PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters.

This commits removes the ASSERT case 4) and add the following new ASSERT
case:
4) The input parameter 'BufferSize' is greater than
(PcdMaximumAsciiStringLength * sizeof (CHAR8)) for Ascii format string or
(PcdMaximumUnicodeStringLength * sizeof (CHAR16) + 1) for Unicode format
string.

And for those ASSERT cases, 0 will be returned by those 12 APIs.

For the following 2 APIs in MdePkg/BasePrintLib:
SPrintLength
SPrintLengthAsciiFormat

They will ASSERT when:
1) The input parameter 'FormatString' is NULL.
2) The input parameter 'FormatString' contains more than
PcdMaximum[Ascii|Unicode]StringLength Ascii/Unicode characters.

And for those ASSERT cases, 0 will be returned by those 2 APIs.

Star Zeng 6d11b822a3 MdePkg DxeHobLib: Make GetHobList working before Constructor is called
The latest PiSmmCore driver added several debug messages in the
function SmmAddMemoryRegion in Page.c. The function SmmAddMemoryRegion
is called by the library constructor
PiSmmCoreMemoryAllocationLibConstructor.

When PiSmmCoreMemoryAllocationLibConstructor is executed, the
constructor of DxeHobLib (HobLibConstructor in HobLib.c) is not
executed yet. But platform instance of DebugLib may need get hob
before printing any message. As a result, an ASSERT happens in the
function GetHobList.

The patch is to update GetHobList to get HOB list from system
configuration table when the HOB list is not retrieved and not cached
yet, and HobLibConstructor is also to be updated to just call
GetHobList.
