Currently the FMMT tool supports CRC32 GUID section (Ref. GuidTools.py).
But it is found that there are errors for the FV with CRC32 section.
For example, the errors are checked on the following commands.
--v : Show FV information except for the FV
--a : Show "Target Fv not found!!!" when adding an FFS file to the FV
--d : Show "Target Ffs not found!!!" when deleting an FFS file in the FV
They are caused by the mismatch for CRC32 section data between the FMMT
and GenCrc32 tools. The FMMT tool returns CRC32 section data without CRC
checksum field (4 bytes). The GenCrc32 tool (with -d option, verify CRC32
value for the input file) requires CRC32 section data including CRC
checksum field (4 bytes).
Fix the issue through adjusting the section data to include CRC checksum
field. Currently DataOffset field for CRC32 GUID section is reported as
0x1C differently (GUID Section header length: 0x18 + Checksum field: 0x4).
Instead of DataOffset field that includes CRC checksum field, configure
the section data based on the offset from section header length (0x18)
that was previously calculated. This update enables GUID sections to use
the same offset consistently.

Subject Check was added to PatchCheck.py to enforce that if a package
was touched in a commit that it be referenced in the subject line.
However, this is impractical for multipackage commits with many
packages, e.g. when stack cookies were added, every package was
touched, but in a rote way, and it is not reasonable to put every
package in a subject line.
This updates PatchCheck.py to check if ignore_multi_package is set
and if so only require that package names be included in the subject
if there are fewer than 3 packages touched. Otherwise, PatchCheck will
require the message to start with `Global:` to indicate it touches
more than 3 packages.

Commit f0a2015373 ("UefiPayloadPkg: Add AARCH64 support") changed
`[Components.X64]` to `[Components.X64, Components.AARCH64]` which
resulted in the following code within that section to not work as
expected (the code wasn't there, just providing a real world example
that uncovered the issue):
[Components.X64, Components.AARCH64]
FmpDevicePkg/FmpDxe/FmpDxe.inf {
...
<PcdsFixedAtBuild>
!include .../...PcdFmpDevicePkcs7CertBufferXdr.inc
...
}
At the same time `[Components.X64]` or even `[Components.AARCH64,
Components.X64]` (notice the swapped order) worked fine for X64 target.
The cause of the issue turned out to be skipping includes inside
`_PostProcess()` method of `DscParser` class. This method processes
list of items stored in a database filled on the first pass through a
DSC file in `Start()` method. One of the fields stored in each row
of a table is link to a parent object (owner). A section like
`[Components.X64, Components.AARCH64]` creates two objects and all of
its subelements are duplicated for both X64 and AARCH64. This was not
happening for !include statement in the example above.
Because `_PostProcess()` contracted a sequence of !include objects
disregarding their owner, it did not create instance for each of the
requested targets. Codewise, `self._ContentIndex` was incremented more
than once, while `__ProcessDirective()` method (invoked indirectly as
`Processer[self._ItemType]()`) queried owner of the current directive
as:
if self._InSubsection:
Owner = self._Content[self._ContentIndex - 1][8]
else: # not taken in this case
This is why order of targets made a difference, only the last was fully
initialized in this case.
An alternative fix is completely dropping merging of !include
directives, but hard to say whether it still has some utility (the code
is complex, hard to follow and barely documented). Safer to keep it, in
the worst case it doesn't do anything now.

Commit a257988f59 added -Wl,-z,notext, but
only when linking for IA32/X64 with LLD.
BFD can also be configured to either warn or error when text relocations
are detected. It does not check at all by default, but Gentoo Linux
tells it to warn in its regular configuration and tells it to error in
its hardened configuration.
Commit 14cb48b0a0 made linker warnings
fatal in all BFD cases. At least the AARCH64 and IA32/X64 code does
include text relocations, so this now fails to build on Gentoo Linux.
We should therefore always use -Wl,-z,notext.

These haven't been used since before 2d07607d8b,

The recent change in 14cb48b0a0 to make

Update the CLANGPDB toolchain configuration to use MSVC ABI targets and
retain frame pointers in generated code. This improves compatibility with
the Microsoft Debug Interface Access (DIA) SDK and improves debuggability
with any debugger that uses the Microsoft PDB parser, for example the Visual
Studio debugger or windbg.
Without these changes, code generated by the Clang compiler will have a mix
of calling conventions. With the current configuration, any function declared
with EFIAPI will use the Microsoft x64 calling convention. However, the default
calling convention will be the SysV x64 calling convention. This mixing of
calling conventions prevents debuggers from decoding the call stack.
With these changes, only the Microsoft x64 calling convention will be used.
These modifications enable debuggers to properly parse and
display call stacks on binaries built with the CLANGPDB toolchain.
The changes include:
- Switch from GNU ABI target (*-unknown-windowsl-gnu) to MSVC ABI targets
(*-pc-windows-msvc) for both IA32 and X64 architectures.
- Remove -fseh-exceptions as not supported.
- Add -fno-omit-frame-pointer as required for call stack.
- Undefine the _MSC_VER macro, and define the __GNUC__ macro, so that
pre-processor conditionals will continue to function as expected.

Before doing the subject line length check, the script checks that the

However, then the test for whether the subject line starts with a CVE
