Abner Chang 74b5309da9 RedfishPkg/RestJsonStructureDxe: Refine REST JSON C Structure DXE driver
BZ #: 4711
- Add mode debug messages.
- Remove the references of "Redfish" from this driver.
  As REST JSON C Structure was not designed for Redfish only.
  Any RESTful applications can register the converter and
  provide JSON-C structure conversions through
  EFI_REST_JSON_STRUCTURE_PROTOCOL. Therefore this driver
  shouldn't have a dependency on Redfish package and the
  references of "Redfish" terminology.
- Fix the missing parameter of DEBUG macros used in this
  driver.

Michael Kubacki 33c81c25bb MdeModulePkg/TraceHubDebugSysTLib: Use wider type for loop comparisons
Resolves a new CodeQL error due to the value being incremented in the
loop being a narrower type than the variable it is being compared
against.

The variable is changed to a UINT32 type so it has the same width as
the type it is being compared against.

Issue explanation: In a loop condition, comparison of a value of a
narrow type with a value of a wide type may result in unexpected
behavior if the wider value is sufficiently large (or small). This
is because the narrower value may overflow. This can lead to an
infinite loop.

table is not changed, and add ASSERT to check. But hardware may change

Laszlo Ersek edc6681206 UefiCpuPkg/PiSmmCpuDxeSmm: fix NULL deref when gSmmBaseHobGuid is missing
Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=4682
Fixes: 725acd0b9c

Before commit 725acd0b9c ("UefiCpuPkg: Avoid assuming only one
smmbasehob", 2023-12-12), PiCpuSmmEntry() used to look up
"gSmmBaseHobGuid", and allocate "mCpuHotPlugData.SmBase" regardless of the
GUID's presence:

> -  mCpuHotPlugData.SmBase = (UINTN *)AllocatePool (sizeof (UINTN) * mMaxNumberOfCpus);
> -  ASSERT (mCpuHotPlugData.SmBase != NULL);

After commit 725acd0b9c, PiCpuSmmEntry() -> GetSmBase() would allocate
"mCpuHotPlugData.SmBase" only on the success path, and no allocation would
be performed on *any* of the error paths.

This caused a problem: if "mCpuHotPlugData.SmBase" was left NULL because
the GUID HOB was missing, PiCpuSmmEntry() would still be supposed to
allocate "mCpuHotPlugData.SmBase", just like earlier. However, because
commit 725acd0b9c conflated the two possible error modes (out of SMRAM,
and no GUID HOB), PiCpuSmmEntry() could not decide whether it should
allocate "mCpuHotPlugData.SmBase", or not. Currently, we never allocate if
GetSmBase() fails -- for any reason --, which means that on platforms that
don't produce the GUID HOB, "mCpuHotPlugData.SmBase" is left NULL, leading
to null pointer dereferences later, in PiCpuSmmEntry().

Now that a prior patch in the series distinguishes the two error modes
from each other, we can tell exactly when the GUID HOB is not found, and
reinstate the earlier "mCpuHotPlugData.SmBase" allocation for that case.
(With an actual error check thrown in, in addition to the original
"assertion".)

Laszlo Ersek 72c441df36 UefiCpuPkg/PiSmmCpuDxeSmm: distinguish GetSmBase() failure modes
Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=4682

Commit 725acd0b9c ("UefiCpuPkg: Avoid assuming only one smmbasehob",
2023-12-12) introduced a helper function called GetSmBase(), replacing
the lookup of the first and only "gSmmBaseHobGuid" GUID HOB and
unconditional "mCpuHotPlugData.SmBase" allocation, with iterated lookups
plus conditional memory allocation.

This introduced a new failure mode for setting "mCpuHotPlugData.SmBase".
Namely, before commit 725acd0b9c, "mCpuHotPlugData.SmBase" would be
allocated regardless of the GUID HOB being absent. After the commit,
"mCpuHotPlugData.SmBase" could remain NULL if the GUID HOB was absent,
*or* one of the memory allocations inside GetSmBase() failed; and in the
former case, we'd even proceed to the rest of PiCpuSmmEntry().

In relation to this conflation of distinct failure modes, commit
725acd0b9c actually introduced a NULL pointer dereference. Namely, a
NULL "mCpuHotPlugData.SmBase" is not handled properly at all now. We're
going to fix that NULL pointer dereference in a subsequent patch; however,
as a pre-requisite for that we need to tell apart the failure modes of
GetSmBase().

For memory allocation failures, return EFI_OUT_OF_RESOURCES. Move the
"assertion" that SMRAM cannot be exhausted happen out to the caller
(PiCpuSmmEntry()). Strengthen the assertion by adding an explicit
CpuDeadLoop() call. (Note: GetSmBase() *already* calls CpuDeadLoop() if
(NumberOfProcessors != MaxNumberOfCpus).)

For the absence of the GUID HOB, return EFI_NOT_FOUND.

For good measure, make GetSmBase() STATIC (it should have been STATIC from
the start).

This is just a refactoring, no behavioral difference is intended (beyond
the explicit CpuDeadLoop() upon SMRAM exhaustion).

This was not part of the Quarkslab bugs however the same pattern
as CVE-2023-45229 exists in Dhcp6UpdateIaInfo.

This patch replaces the code in question with the safe function
created to patch CVE-2023-45229

Michael D Kinney a1c426e844 UnitTestFrameworkPkg: Add DSC and host tests that always fail
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4683

Add sample unit tests that always fail or generate unexpected
exceptions along with a new DSC file to build the unit tests
that always fail or generate unexpected exceptions. This can
be used to verify the log information on failures is accurate
and provides the correct information to determine the source
of the unit test failure.

Divide by zero is used to generate unexpected exceptions.  The
compiler warnings for divide by zero are disables for the unit
tests that generate divide by zero exceptions on purpose.

These tests are not added to CI because CI would always fail.

The UnitTestFrameworkPkg.ci.yaml file is updated to ignore the
INF files for host-based testing that always fail.

Michael D Kinney 0a989069df UnitTestFrameworkPkg/SampleGoogleTest: Use EXPECT_ANY_THROW()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4683

Update GoogleTest samples to use EXPECT_ANY_THROW() instead
of ASSERT_DEATH(). ASSERT_DEATH() is a very slow method to
detect an expected ASSERT() condition. Throwing an exception
from ASSERT() and using EXPECT_ANY_THROW() is several orders
of magnitude faster.

Update GoogleTest sample with example of using EXPECT_THROW()
and EXPECT_THAT() to check for more specific ASSERT() conditions
that allow unit test cases to test functions that contain
more than one ASSERT() statement and verify that the expected
ASSERT() is the one that was actually triggered.

Update library mappings so target-based unit tests use
UnitTestDebugAssertLib.inf and host-based unit tests use
UnitTestDebugAssertLibHost.inf
