Star Zeng 1a0ad70ee1 MdePkg SmmMemLib: Remove ASSERT in SmmIsBufferOutsideSmmValid
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=577

Currently the SmmIsBufferOutsideSmmValid() function in SmmMemLib.c will
ASSERT in certain conditions. Since this function is a "test" function,
it should not be making decisions on how to handle a failure.
Handling a failure should be left to the caller.

This patch is to remove ASSERT(FALSE) at line 178 of SmmMemLib.c.

Hao Wu b1d4b9651e MdePkg/BasePrintLib: Avoid reading content beyond the format string
https://bugzilla.tianocore.org/show_bug.cgi?id=567

In function BasePrintLibSPrintMarker(), when processing ASCII format
strings, if the format string walker pointer 'Format' is pointing at the
end of the format string (i.e. '\0'), the following expression:
*(Format + 1)
will read an undefined value.

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.

Star Zeng d7b96017cc MdePkg DxeServicesLib: Handle potential NULL FvHandle
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=514

The FvHandle input to InternalGetSectionFromFv() may be NULL,
then ASSERT will appear. It is because the LoadedImage->DeviceHandle
returned from InternalImageHandleToFvHandle() may be NULL.
For example for DxeCore, there is LoadedImage protocol installed
for it, but the LoadedImage->DeviceHandle could not be initialized
before the FV2 (contain DxeCore) protocol is installed.

This patch is to update InternalGetSectionFromFv() to return
EFI_NOT_FOUND directly for NULL FvHandle.

Hao Wu 458cd568b6 MdePkg/UefiLib: Avoid mis-calculate of graphic console size
The commit adds check in function InternalPrintGraphic() to ensure that
the expression:

Blt->Width * Blt->Height * sizeof (EFI_GRAPHICS_OUTPUT_BLT_PIXEL)

will not overflow in the UINTN range.

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().

Ruiyu Ni 647636e175 MdePkg/DevicePathLib: Fix FromText bug for multi-instance devicepath
UefiDevicePathLibConvertTextToDevicePath correctly detects when it
has hit a ',' splicing together multiple paths. However, the code
that tries to cope with it:
{code}
if (IsInstanceEnd) {
  DeviceNode = (EFI_DEVICE_PATH_PROTOCOL *) AllocatePool (
                                   END_DEVICE_PATH_LENGTH);
  ASSERT (DeviceNode != NULL);
  SetDevicePathEndNode (DeviceNode);

  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'.

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.

Leo Duran 19c6d9feaa MdePkg: Expand BaseIoLibIntrinsic (IoLib class) library
The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have duplicate
implementations of I/O Fifo routines. This patch clones the I/O Fifo
routines into the BaseIoLibIntrinsic library and expands the IoLib class
to include the ported I/O Fifo routines.

Hao Wu 02263214ef MdePkg/BaseLib: Add safe string functions [U|A]StrnTo[A|U]StrS
Add the following 2 APIs:
UnicodeStrnToAsciiStrS
AsciiStrnToUnicodeStrS

These APIs are used to enhance APIs UnicodeStrToAsciiStrS and
AsciiStrToUnicodeStrS (without 'n' in names) by:
1. Adds an input parameter 'Length' to specify the maximum number of
Ascii/Unicode characters to convert.
2. Adds an output parameter 'DestinationLength' to indicate the number of
Ascii/Unicode characters successfully converted.

Hao Wu ea2e092186 MdePkg/BaseLib: Enhance the return value for string to uint functions
For the following 8 APIs in MdePkg/BaseLib:
[Ascii]StrDecimalToUintn
[Ascii]StrDecimalToUint64
[Ascii]StrHexToUintn
[Ascii]StrHexToUint64

They will ASSERT for DEBUG build when the input string exceeds the range
of UINTN/UINT64. However, for RELEASE build, incorrect value will be
returned.

This commit refines those APIs to direcly call their enhanced counterparts
(with trailing 'S' in API names) so as to remove those exceed-range ASSERT
checks and to make those APIs to return MAX_UINTN/MAX_UINT64 instead.

Hao Wu d8af3301a6 MdePkg/BaseLib: Add safe string functions that convert str to value
Add the following 8 APIs:
[Ascii]StrDecimalToUintnS
[Ascii]StrDecimalToUint64S
[Ascii]StrHexToUintnS
[Ascii]StrHexToUint64S

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

These safe version APIs perform checks to the input string and will return
relative status to reflect the check result:
When the input string exceeds the range of UINTN/64, these APIs will
return RETURN_UNSUPPORTED and store MAX_UINTN/64 in the output data.
When no conversion can be performed for the input string, these APIs will
return RETURN_SUCCESS and store 0 in the output data.

The optional parameter 'EndPointer', if provided, will point to the
character that stopped the scan.

Laszlo Ersek 63042a7188 MdePkg, MdeModulePkg: S3BootScriptSaveMemPoll(): accept 64-bit LoopTimes
The BaseNull instance of S3BootScriptLib obviously doesn't care about the
type of the S3BootScriptSaveMemPoll() function's LoopTimes parameter; this
lib instance doesn't do anything with the parameters received in
S3BootScriptSaveMemPoll().

The PiDxe instance saves the LoopTimes parameter in
EFI_BOOT_SCRIPT_MEM_POLL.LoopTimes. This target field already has UINT64
type. Furthermore, the BootScriptExecuteMemPoll() function in the same
library instance already uses a local UINT64 variable called LoopTimes to
count up to EFI_BOOT_SCRIPT_MEM_POLL.LoopTimes. This means that the the
UINTN type for S3BootScriptSaveMemPoll()'s LoopTimes parameter is an
unnecessary restriction.

The callers of S3BootScriptSaveMemPoll() will be updated in the next
patches, functionally. At this stage, they will continue to compile, since
UINT64 parameters can accept UINTN arguments.

Hao Wu 9088c61e2d MdePkg/MemoryLib: Refine InternalMemSetMem16|32|64 functions logic
This commit refines the logic for InternalMemSetMem16|32|64 functions. It
avoids using the decrement operator '--' for array index to prevent
possible mis-reports by static code checkers.

Please note that those modified functions are only consumed within
MemoryLib by APIs SetMem16|32|64, and those APIs will handle the case when
the input number of bytes to set is 0. Hence, the behavior of APIs
SetMem16|32|64 is not changed.

When the input path for API PathRemoveLastItem() is a root path like
'fs0:\', the API will return TRUE (indicating a directory or file was
