PcdIdentifyMappingPageTablePtr was used to share page
table buffer between modules.
Buf after some changes on 2015/07/17, it was useless
and could be removed.

UAF (Use-After-Free) memory issue is kind of illegal access to memory
which has been freed. It can be detected by a new freed-memory guard
enforced onto freed memory.
BIT4 of following PCD is used to enable the freed-memory guard feature.
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask
Please note this feature is for debug purpose and should not be enabled
in product BIOS, and cannot be enabled with pool/page heap guard at the
same time. It's disabled by default.

This cleanup is meant for avoiding misuse of newly introduced BIT4
(UAF detection) of PCD PcdHeapGuardPropertyMask, because it applies
to all types of physical memory. In another words,
PcdHeapGuardPoolType and PcdHeapGuardPageType don't have effect to
the BIT4 of PcdHeapGuardPropertyMask.

BZ#1116: https://bugzilla.tianocore.org/show_bug.cgi?id=1116
The usage of following PCDs described in MdeModulePkg.dec don't match
the implementation exactly. This patch updates related description in
both .dec and .uni files to avoid confusion in platform configuration.
PcdSetNxForStack
PcdImageProtectionPolicy
PcdDxeNxMemoryProtectionPolicy
The main change is at the statement on how to handle the FALSE or 0
setting value in those PCDs. Current statement says the implementation
should unset or disable related features but in fact the related code
just do nothing (leave it to AS-IS). That means the result might be
disabled, or might be not. It depends on other features or platform
policy.
For example, if one don't want to enforce NX onto stack memory, he/she
needs to set PcdSetNxForStack to FALSE as well as to clear BIT4 of
PcdDxeNxMemoryProtectionPolicy.

The variable driver doesn't distinguish "non-volatile non-authenticated"
variables from "volatile non-authenticated" variables, when checking
individual variable sizes against the permitted maximum.
PcdMaxVariableSize covers both kinds.
This prevents volatile non-authenticated variables from carrying large
data between UEFI drivers, despite having no flash impact. One example is
EFI_TLS_CA_CERTIFICATE_VARIABLE, which platforms might want to create as
volatile on every boot: the certificate list can be several hundred KB in
size.
Introduce PcdMaxVolatileVariableSize to represent the limit on individual
volatile non-authenticated variables. The default value is zero, which
makes Variable/RuntimeDxe fall back to PcdMaxVariableSize (i.e. the
current behavior). This is similar to the PcdMaxAuthVariableSize fallback.
Whenever the size limit is enforced, consult MaxVolatileVariableSize as
the last option, after checking
- MaxAuthVariableSize for VARIABLE_ATTRIBUTE_AT_AW,
- and MaxVariableSize for EFI_VARIABLE_NON_VOLATILE.
EFI_VARIABLE_HARDWARE_ERROR_RECORD is always handled separately; it always
takes priority over the three cases listed above.
Introduce the GetMaxVariableSize() helper to consider
PcdMaxVolatileVariableSize, in addition to
GetNonVolatileMaxVariableSize(). GetNonVolatileMaxVariableSize() is
currently called at three sites, and two of those need to start using
GetMaxVariableSize() instead:
- VariableServiceInitialize() [VariableSmm.c]: the SMM comms buffer must
accommodate all kinds of variables,
- VariableCommonInitialize() [Variable.c]: the preallocated scratch space
must also accommodate all kinds of variables,
- InitNonVolatileVariableStore() [Variable.c] can continue using
GetNonVolatileMaxVariableSize().
Don't modify the ReclaimForOS() function as it is specific to non-volatile
variables and should ignore PcdMaxVolatileVariableSize.

PCD PcdNullPointerDetectionPropertyMask is a bitmask used to control the
NULL address detection functionality in code for different phases.
If enabled, accessing NULL address in UEFI or SMM code can be caught
as a page fault exception.
BIT0 - Enable NULL pointer detection for UEFI.
BIT1 - Enable NULL pointer detection for SMM.
BIT2..6 - Reserved for future uses.
BIT7 - Disable NULL pointer detection just after EndOfDxe. This is a
workaround for those unsolvable NULL access issues in
OptionROM, boot loader, etc. It can also help to avoid
unnecessary exception caused by legacy memory (0-4095) access
after EndOfDxe, such as Windows 7 boot on Qemu.

IntelFrameworkModulePkg will be deprecated step by step, so move the

The ACPI global variable related code is leaved as is in IntelFrameworkModulePkg
AcpiS3SaveDxe for compatibility.
PcdS3BootScriptStackSize is also moved from IntelFrameworkModulePkg.
The functional code need to get ACPI FACS table and consume LockBoxLib,
so need to be before DxeSmmReadyToLock that will shut down SMM lock box

What to do:
1. Remove a hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback".
1.1. Use SmmExitBootServices and SmmLegacyBoot notification to record
AtRuntime flag.
1.2. Use mBootScriptDataBootTimeGuid LockBox to save boot time boot
script data to handle potential INSERT boot script at runtime in SMM.
2. Do not depend on OS to help restore ACPINvs data and use
EfiReservedMemoryType instead of EfiACPIMemoryNVS.
2.1. Use mBootScriptSmmPrivateDataGuid LockBox to save boot script
SMM private data with BackFromS3 = TRUE at runtime. S3 resume
will help restore it to tell the Library the system is back
from S3.
Why to do:
1. The hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback" will cause confusion to
the library's consumer and block the usage of "SMM driver writes
BootScript after SmmReadyToLock". So Remove the assumption.
2. In original code, there might be a corner case that malicious
code patch ACPINvs boot TableLength field same as SMM boot script.
So that it can skip the table restore. The impact is that BootScript
in SMM may be overridden by malicious code.
--------------------
CopyMem ((VOID*)&TableHeader, (VOID*)mS3BootScriptTablePtr->TableBase, sizeof(EFI_BOOT_SCRIPT_TABLE_HEADER));
if (mS3BootScriptTablePtr->TableLength + sizeof(EFI_BOOT_SCRIPT_TERMINATE) != TableHeader.TableLength) { // TableLength is in NVS
......
//
// NOTE: We should NOT use TableHeader.TableLength, because it is already updated to be whole length.
//
mS3BootScriptTablePtr->TableLength = (UINT32)(mLockBoxLength - sizeof(EFI_BOOT_SCRIPT_TERMINATE)); ? This line can be skipped.
--------------------
So use EfiReservedMemoryType instead of EfiACPIMemoryNVS as the code
has been updated to not depend on OS to help restore ACPINvs data.
