Philippe Mathieu-Daudé 4b026f0d5a SecurityPkg: Fix incorrect return value when File is NULL
The DxeTpmMeasureBootHandler and DxeTpm2MeasureBootHandler handlers
are SECURITY2_FILE_AUTHENTICATION_HANDLER prototype. This prototype
can not return EFI_INVALID_PARAMETER.

The prototype documentation states it returns EFI_ACCESS_DENIED if:

  "The file specified by File and FileBuffer did not authenticate,
   and the platform policy dictates that the DXE Foundation may not
   use File."

Correct the documentation, and add a early check, returning
EFI_ACCESS_DENIED when File is NULL.

Noticed while reviewing commit 6d57592740.

Based on the following package with changes to merge into
CryptoPkg.

https://github.com/microsoft/mu_plus/tree/dev/201908/SharedCryptoPkg

Add the CryptoPei, CryptoDxe, and CryptoSmm modules that produce
EDK II Crypto Protocols/PPIs that provide the same services as
the BaseCryptLib class.

In order to optimize the size of CryptoPei, CryptoDxe, and
CryptoSmm modules for a specific platform, the FixedAtBuild
PCD gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable
is used to determine if a specific service is enabled or
disabled.  If a service is enabled, then a call is made to
the BaseCryptLib service.  If the service is disabled, then
a DEBUG() message and ASSERT() are performed and a default
return value is returned.  This provides simple detection
of a service that is disabled but is used by another module
when DEBUG()/ASSERT() macros are enabled.

The use of a FixedAtBuild PCD is required so the compiler
and linker know each services enable/disable setting at
build time and allows disabled services to be optimized away.

CryptoPei supports both pre-mem and post-mem use cases.
If CryptoPei is initially dispatched pre-mmem, the the
register for shadow service is used so the Crypto PPI can
be reinstalled post-mem.

happen if pre-compiled BaseToools are used.  Change the
makefile for the Structure PCD application to build all
files from sources which adds PcdValueCommon.c to the
makefile.  Also remove PcdValueCommon.c from Common.lib.

With the change to the makefile for the Structured PCD
application, multiple C files are compiled.  Only
PcdValueInit.c contains the extra information expected
by the error/warning message parser.  Only parse the
DSC line number into an error message if there is an
error/warning in PcdValueInit.c.  Errors/warnings in
other files should be passed through.  This fixes a build
failure with no useful log information that was observed
when there was a compiler error in PcdValueCommon.c.

Steven 77b738b36f BaseTools: Enhance call stack unwindability for CLANGPDB x64 binary
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2487

The call stack unwindability of the COFF X64 binary requires
the binary to remain the pdata and xdata sections.
Details see the MSVC X64 calling convertion doc in below link:
https://docs.microsoft.com/en-us/cpp/build/x64-calling-convention

Current build options discard or zero the data in pdata and xdata
sections which cause the debugger cannot correctly unwind the
X64 binary call stack in the runtime.
Enhance the build options to force emit the unwind tables and
keep the data of pdata and xdata sections correct in the binary.

Pierre Gondois 1549651da6 BaseTools: Script for converting .aml to .hex
The "-tc" option of the iasl compiler allows to generate a
.hex file containing a C array storing AML bytecode.

An online discussion suggested that this "-tc" option
was specific to the iasl compiler and it shouldn't be relied
on. This conversation is available at:
https://edk2.groups.io/g/devel/topic/39786201#49659

A way to address this issue is to implement a compiler
independent script that takes an AML file as input, and
generates a .hex file.

This patch implements a Python script that converts an AML
file to a .hex file, containing a C array storing AML bytecode.
This scipt has been tested with the AML output from the
following compilers supported by the EDKII implementation:
  * Intel ASL compiler
  * Microsoft ASL compiler

Hao A Wu a9e3458ba7 UefiCpuPkg/MpInitLib: Always get CPUID & PlatformID in MicrocodeDetect()
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2498

Commit fd30b00707 updated the logic in function MicrocodeDetect() that
will directly use the CPUID and PlatformID information from the 'CpuData'
field in the CPU_MP_DATA structure, instead of collecting these
information for each processor via AsmCpuid() and AsmReadMsr64() calls
respectively.

At that moment, this approach worked fine for APs. Since:
a) When the APs are waken up for the 1st time (1st MpInitLibInitialize()
   entry at PEI phase), the function InitializeApData() will be called for
   each AP and the CPUID and PlatformID information will be collected.

b) During the 2nd entry of MpInitLibInitialize() at DXE phase, when the
   APs are waken up again, the function InitializeApData() will not be
   called, which means the CPUID and PlatformID information will not be
   collected. However, the below logics in MicrocodeDetect() function:

  CurrentRevision = GetCurrentMicrocodeSignature ();
  IsBspCallIn     = (ProcessorNumber == (UINTN)CpuMpData->BspNumber) ? TRUE : FALSE;
  if (CurrentRevision != 0 && !IsBspCallIn) {
    //
    // Skip loading microcode if it has been loaded successfully
    //
    return;
  }

   will ensure that the microcode detection and application will be
   skipped due to the fact that such process has already been done in the
   PEI phase.

But after commit 396e791059, which removes the above skip loading logic,
the CPUID and PlatformID information on APs will be used upon the 2nd
entry of the MpInitLibInitialize(). But since the CPUID and PlatformID
information has not been collected, it will bring issue to the microcode
detection process.

This commit will update the logic in MicrocodeDetect() back to always
collecting the CPUID and PlatformID information explicitly.

Laszlo Ersek 75839f977d OvmfPkg/PlatformPei: detect SMRAM at default SMBASE (for real)
Now that the SMRAM at the default SMBASE is honored everywhere necessary,
implement the actual detection. The (simple) steps are described in
previous patch "OvmfPkg/IndustryStandard: add MCH_DEFAULT_SMBASE* register
macros".

Regarding CSM_ENABLE builds: according to the discussion with Jiewen at

  https://edk2.groups.io/g/devel/message/48082
  http://mid.mail-archive.com/74D8A39837DF1E4DA445A8C0B3885C503F7C9D2F@shsmsx102.ccr.corp.intel.com

if the platform has SMRAM at the default SMBASE, then we have to

(a) either punch a hole in the legacy E820 map as well, in
    LegacyBiosBuildE820() [OvmfPkg/Csm/LegacyBiosDxe/LegacyBootSupport.c],

(b) or document, or programmatically catch, the incompatibility between
    the "SMRAM at default SMBASE" and "CSM" features.

Because CSM is out of scope for the larger "VCPU hotplug with SMM"
feature, option (b) applies. Therefore, if the CSM is enabled in the OVMF
build, then PlatformPei will not attempt to detect SMRAM at the default
SMBASE, at all. This is approach (4) -- the most flexible one, for
end-users -- from:

Laszlo Ersek 9108fc17b0 OvmfPkg/SmmAccess: close and lock SMRAM at default SMBASE
During normal boot, when EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed
by platform BDS, the SMM IPL locks SMRAM (TSEG) through
EFI_SMM_ACCESS2_PROTOCOL.Lock(). See SmmIplReadyToLockEventNotify() in
"MdeModulePkg/Core/PiSmmCore/PiSmmIpl.c".

During S3 resume, S3Resume2Pei locks SMRAM (TSEG) through
PEI_SMM_ACCESS_PPI.Lock(), before executing the boot script. See
S3ResumeExecuteBootScript() in
"UefiCpuPkg/Universal/Acpi/S3Resume2Pei/S3Resume.c".

Those are precisely the places where the SMRAM at the default SMBASE
should be locked too. Add such an action to SmramAccessLock().

Notes:

- The SMRAM at the default SMBASE doesn't support the "closed and
  unlocked" state (and so it can't be closed without locking it, and it
  cannot be opened after closing it).

- The SMRAM at the default SMBASE isn't (and shouldn't) be exposed with
  another EFI_SMRAM_DESCRIPTOR in the GetCapabilities() members of
  EFI_SMM_ACCESS2_PROTOCOL / PEI_SMM_ACCESS_PPI. That's because the SMRAM
  in question is not "general purpose"; it's only QEMU's solution to
  protect the initial SMI handler from the OS, when a VCPU is hot-plugged.

  Consequently, the state of the SMRAM at the default SMBASE is not
  reflected in the "OpenState" / "LockState" fields of the protocol and
  PPI.

- An alternative to extending SmramAccessLock() would be to register an
  EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL notify in SmmAccess2Dxe (for locking
  at normal boot), and an EDKII_S3_SMM_INIT_DONE_GUID PPI notify in
  SmmAccessPei (for locking at S3 resume).

Laszlo Ersek 300aae1180 OvmfPkg/SEV: don't manage the lifecycle of the SMRAM at the default SMBASE
When OVMF runs in a SEV guest, the initial SMM Save State Map is

(1) allocated as EfiBootServicesData type memory in OvmfPkg/PlatformPei,
    function AmdSevInitialize(), for preventing unintended information
    sharing with the hypervisor;

(2) decrypted in AmdSevDxe;

(3) re-encrypted in OvmfPkg/Library/SmmCpuFeaturesLib, function
    SmmCpuFeaturesSmmRelocationComplete(), which is called by
    PiSmmCpuDxeSmm right after initial SMBASE relocation;

(4) released to DXE at the same location.

The SMRAM at the default SMBASE is a superset of the initial Save State
Map. The reserved memory allocation in InitializeRamRegions(), from the
previous patch, must override the allocating and freeing in (1) and (4),
respectively. (Note: the decrypting and re-encrypting in (2) and (3) are
unaffected.)

In AmdSevInitialize(), only assert the containment of the initial Save
State Map, in the larger area already allocated by InitializeRamRegions().

In SmmCpuFeaturesSmmRelocationComplete(), preserve the allocation of the
initial Save State Map into OS runtime, as part of the allocation done by
InitializeRamRegions(). Only assert containment.

These changes only affect the normal boot path (the UEFI memory map is
untouched during S3 resume).

Laszlo Ersek 84b223c18c OvmfPkg/PlatformPei: reserve the SMRAM at the default SMBASE, if it exists
The 128KB SMRAM at the default SMBASE will be used for protecting the
initial SMI handler for hot-plugged VCPUs. After platform reset, the SMRAM
in question is open (and looks just like RAM). When BDS signals
EFI_DXE_MM_READY_TO_LOCK_PROTOCOL (and so TSEG is locked down), we're
going to lock the SMRAM at the default SMBASE too.

For this, we have to reserve said SMRAM area as early as possible, from
components in PEI, DXE, and OS runtime.

* QemuInitializeRam() currently produces a single resource descriptor HOB,
  for exposing the system RAM available under 1GB. This occurs during both
  normal boot and S3 resume identically (the latter only for the sake of
  CpuMpPei borrowing low RAM for the AP startup vector).

  But, the SMRAM at the default SMBASE falls in the middle of the current
  system RAM HOB. Split the HOB, and cover the SMRAM with a reserved
  memory HOB in the middle. CpuMpPei (via MpInitLib) skips reserved memory
  HOBs.

* InitializeRamRegions() is responsible for producing memory allocation
  HOBs, carving out parts of the resource descriptor HOBs produced in
  QemuInitializeRam(). Allocate the above-introduced reserved memory
  region in full, similarly to how we treat TSEG, so that DXE and the OS
  avoid the locked SMRAM (black hole) in this area.

  (Note that these allocations only occur on the normal boot path, as they
  matter for the UEFI memory map, which cannot be changed during S3
  resume.)

The permanent PEI RAM that is published on the normal boot path starts
strictly above MEMFD_BASE_ADDRESS (8 MB -- see the FDF files), regardless
of whether PEI decompression will be necessary on S3 resume due to
SMM_REQUIRE. Therefore the normal boot permanent PEI RAM never overlaps
with the SMRAM at the default SMBASE (192 KB).

The S3 resume permanent PEI RAM is strictly above the normal boot one.
Therefore the no-overlap statement holds true on the S3 resume path as
well.

Assert the no-overlap condition commonly for both boot paths in

Laszlo Ersek 04ff9d663b OvmfPkg/IndustryStandard: add MCH_DEFAULT_SMBASE* register macros
In Intel datasheet 316966-002 (the "q35 spec"), Table 5-1 "DRAM Controller
Register Address Map (D0:F0)" leaves the byte register at config space
offset 0x9C unused.

On QEMU's Q35 board, for detecting the "SMRAM at default SMBASE" feature,
firmware is expected to write MCH_DEFAULT_SMBASE_QUERY (0xFF) to offset
MCH_DEFAULT_SMBASE_CTL (0x9C), and read back the register. If the value is
MCH_DEFAULT_SMBASE_IN_RAM (0x01), then the feature is available, and the
range mentioned below is open (accessible to code running outside of SMM).

Then, once firmware writes MCH_DEFAULT_SMBASE_LCK (0x02) to the register,
the MCH_DEFAULT_SMBASE_SIZE (128KB) range at 0x3_0000 (SMM_DEFAULT_SMBASE)
gets closed and locked down, and the register becomes read-only. The area
is reopened, and the register becomes read/write, at platform reset.

Add the above-listed macros to "Q35MchIch9.h".

(There are some other unused offsets in Table 5-1; for example we had
scavenged 0x50 for implementing the extended TSEG feature. 0x9C is the
first byte-wide register standing in isolation after 0x50.)
