An example:
The codes in function Output8bitPixel in Image.c:
OffsetY = BITMAP_LEN_8_BIT ((UINT32) Image->Width, Ypos);
Both Image->Width and Ypos are of type UINT16. They will be promoted to
int (signed) first, and then perform the multiplication defined by macro
BITMAP_LEN_8_BIT. If the result of multiplication between Image->Width and
Ypos exceeds the range of type int, a potential incorrect results
will be assigned to OffsetY.
This commit adds explicit UINT32 type cast for 'Image->Width' to avoid
possible overflow in the int range. And also fix similar issues in

The EFI_IMAGE_MACHINE_TYPE_SUPPORTED() macro is abused in the PeiCore

As stated in the comment, this is fundamentally a property of the compiler
target, and so this should be made dependent on MDE_CPU_xxx preprocessor
defines, and not on whether or not the runtime target can deal with
PE/COFF images of a certain machine type.

Currently, the PE/COFF image memory protection code uses the same code
paths for protecting and unprotecting an image. This is strange, since
unprotecting an image involves a single call into the CPU arch protocol
to clear the permission attributes of the entire range, and there is no
need to parse the PE/COFF headers again.
So let's store the ImageRecord entries in a linked list, so we can find
it again at unprotect time, and simply clear the permissions.
Note that this fixes a DEBUG hang on an ASSERT() that occurs when the
PE/COFF image fails to load, which causes UnprotectUefiImage() to be
invoked before the image is fully loaded.

When attempting to perform page allocations using AllocateAddress, we
fail to check whether the entire region is free before splitting the
region. This may lead to memory being leaked further into the routine,
when it turns out that one of the memory map entries intersected by the
region is already occupied. In this case, prior conversions are not rolled
back.
For instance, starting from this situation
0x000040000000-0x00004007ffff [ConventionalMemory ]
0x000040080000-0x00004009ffff [Boot Data ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]
a failed EfiLoaderData allocation @ 0x40000000 that covers the BootData
region will fail, but leave the first part of the allocation converted,
so we end up with
0x000040000000-0x00004007ffff [Loader Data ]
0x000040080000-0x00004009ffff [Boot Data ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]
even though the AllocatePages() call returned an error.
So let's check beforehand that AllocateAddress allocations are covered
by a single memory map entry, so that it either succeeds or fails
completely, rather than leaking allocations.

The ACPI specification, up to and including revision 5.1 Errata A, allows
the DSDT and X_DSDT fields to be both set in the FADT. (Obviously, this
only makes sense if the DSDT address is representable in 4 bytes.)
Starting with 5.1 Errata B, specifically for Mantis 1393
<https://mantis.uefi.org/mantis/view.php?id=1393>, the spec requires at
most one of DSDT and X_DSDT to be set to a nonzero value.
MdeModulePkg/AcpiTableDxe handles this mutual exclusion somewhat
inconsistently.
- If the caller of EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() installs the
tables in "DSDT, FADT" order, then we enforce the exclusion between the
DSDT and X_DSDT fields:
DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT B]
-------------- --------- -----------
yes set clear
no clear set
This behavior conforms to 5.1 Errata B. (And it's not required by
earlier versions of the spec.)
- If the caller passes in the tables in "FADT, DSDT" relative order, then
we do not enforce the exclusion:
DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT A]
-------------- --------- -----------
yes set set
no clear set
This satisfies 5.1 Errata A and earlier, but breaks 5.1 Errata B and
later.
Unify the handling of both relative orders. In particular, check the major
and minor version numbers in the FADT. If the FADT version is strictly
before 5.1, then implement [VARIANT A]. If the FADT version is equal to or
larger than 5.1, then implement [VARIANT B].
We make three observations:
- We can't check the FADT table version precisely against "5.1 Errata B";
erratum levels are not captured in the table. We err in the safe
direction, namely we enforce the exclusion for "5.1" and "5.1 Errata A".
- The same applies to "6.0" versus "6.0 Errata A". Because we cannot
distinguish these two, we consider "6.0" to be "equal to or larger than
5.1", and apply [VARIANT B], enforcing the exclusion.
- While a blanket [VARIANT B] would be simpler, there is a significant
benefit to [VARIANT A], under the spec versions that permit it:
compatibility with a wider range of OSPMs (typically, older ones).
For example, Igor reported about a "DELL R430 system with rev4 FADT
where DSDT and X_DSDT are pointing to the same address". Michael also
reported about several systems that exhibit the same.

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'.

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;

This implements a DXE memory protection policy that ensures that regions
that don't require executable permissions are mapped with the non-exec
attribute set.
First of all, it iterates over all entries in the UEFI memory map, and
removes executable permissions according to the configured DXE memory
protection policy, as recorded in PcdDxeNxMemoryProtectionPolicy.
Secondly, it sets or clears the non-executable attribute when allocating
or freeing pages, both for page based or pool based allocations.
Note that this complements the image protection facility, which applies
strict permissions to BootServicesCode/RuntimeServicesCode regions when
the section alignment allows it. The memory protection configured by this
patch operates on non-code regions only.

In preparation of adding memory permission attribute management to

a separate lock. This is an improvement in itself, given that pool
allocations can only interfere with the page allocation bookkeeping
if pool pages are allocated or released. But it is also required to
ensure that the permission attribute management does not deadlock,
given that it may trigger page table splits leading to additional
page tables being allocated.

The EBC driver emits thunks for native to EBC calls, which are short
instructions sequences that bridge the gap between the native execution
environment and the EBC virtual machine.
Since these thunks are allocated using MemoryAllocationLib::AllocatePool(),
they are emitted into EfiBootServicesData regions, which does not reflect
the nature of these thunks accurately, and interferes with strict memory
protection policies that map data regions non-executable.
So instead, create a new helper EbcAllocatePoolForThunk() that invokes the
AllocatePool() boot service directly to allocate EfiBootServicesCode pool
memory explicitly, and wire up this helper for the various architecture
specific thunk generation routines.
