The commit message is not overly verbose:
OvmfPkg: Add custom SecureBootConfigDxe that doesn't reset
We don't force a platform reset for OVMF when PK is changed in custom
mode setup.
But the INF file hunk is telling:
Need custom SecureBootConfigDxe for OVMF that does not force resets
after PK changes since OVMF doesn't have persistent variables
We do have persistent variables now. Let's disable the (now obsolete)
OvmfPkg fork, and revert to the (well maintained) SecurityPkg-provided
config driver.

OVMF_VARS.fd and OVMF_CODE.fd split the variable store and the firmware
code in separate files.
The PCDs' values continue to depend only on FD_SIZE_1MB vs. FD_SIZE_2MB.
With the split files, it must be ensured on the QEMU command line that
OVMF_VARS.fd and OVMF_CODE.fd be contiguously mapped so that they end
exactly at 4GB. See QEMU commit 637a5acb (first released in v2.0.0).
In this patch we must take care to assign each PCD only once.

OVMF's SecMain is unique in the sense that it links against the following
two libraries *in combination*:
- IntelFrameworkModulePkg/Library/LzmaCustomDecompressLib/
LzmaCustomDecompressLib.inf
- MdePkg/Library/BaseExtractGuidedSectionLib/
BaseExtractGuidedSectionLib.inf
The ExtractGuidedSectionLib library class allows decompressor modules to
register themselves (keyed by GUID) with it, and it allows clients to
decompress file sections with a registered decompressor module that
matches the section's GUID.
BaseExtractGuidedSectionLib is a library instance (of type BASE) for this
library class. It has no constructor function.
LzmaCustomDecompressLib is a compatible decompressor module (of type
BASE). Its section type GUID is
gLzmaCustomDecompressGuid == EE4E5898-3914-4259-9D6E-DC7BD79403CF
When OVMF's SecMain module starts, the LzmaCustomDecompressLib constructor
function is executed, which registers its LZMA decompressor with the above
GUID, by calling into BaseExtractGuidedSectionLib:
LzmaDecompressLibConstructor() [GuidedSectionExtraction.c]
ExtractGuidedSectionRegisterHandlers() [BaseExtractGuidedSectionLib.c]
GetExtractGuidedSectionHandlerInfo()
PcdGet64 (PcdGuidedExtractHandlerTableAddress) -- NOTE THIS
Later, during a normal (non-S3) boot, SecMain utilizes this decompressor
to get information about, and to decompress, sections of the OVMF firmware
image:
SecCoreStartupWithStack() [OvmfPkg/Sec/SecMain.c]
SecStartupPhase2()
FindAndReportEntryPoints()
FindPeiCoreImageBase()
DecompressMemFvs()
ExtractGuidedSectionGetInfo() [BaseExtractGuidedSectionLib.c]
ExtractGuidedSectionDecode() [BaseExtractGuidedSectionLib.c]
Notably, only the extraction depends on full-config-boot; the registration
of LzmaCustomDecompressLib occurs unconditionally in the SecMain EFI
binary, triggered by the library constructor function.
This is where the bug happens. BaseExtractGuidedSectionLib maintains the
table of GUIDed decompressors (section handlers) at a fixed memory
location; selected by PcdGuidedExtractHandlerTableAddress (declared in
MdePkg.dec). The default value of this PCD is 0x1000000 (16 MB).
This causes SecMain to corrupt guest OS memory during S3, leading to
random crashes. Compare the following two memory dumps, the first taken
right before suspending, the second taken right after resuming a RHEL-7
guest:

The "EGSI" signature corresponds to EXTRACT_HANDLER_INFO_SIGNATURE
declared in
MdePkg/Library/BaseExtractGuidedSectionLib/BaseExtractGuidedSectionLib.c.
Additionally, the gLzmaCustomDecompressGuid (quoted above) is visible at
guest-phys offset 0x1000020.
Fix the problem as follows:
- Carve out 4KB from the 36KB gap that we currently have between
PcdOvmfLockBoxStorageBase + PcdOvmfLockBoxStorageSize == 8220 KB
and
PcdOvmfSecPeiTempRamBase == 8256 KB.
- Point PcdGuidedExtractHandlerTableAddress to 8220 KB (0x00807000).
- Cover the area with an EfiACPIMemoryNVS type memalloc HOB, if S3 is
supported and we're not currently resuming.
The 4KB size that we pick is an upper estimate for
BaseExtractGuidedSectionLib's internal storage size. The latter is
calculated as follows (see GetExtractGuidedSectionHandlerInfo()):
sizeof(EXTRACT_GUIDED_SECTION_HANDLER_INFO) + // 32
PcdMaximumGuidedExtractHandler * (
sizeof(GUID) + // 16
sizeof(EXTRACT_GUIDED_SECTION_DECODE_HANDLER) + // 8
sizeof(EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER) // 8
)
OVMF sets PcdMaximumGuidedExtractHandler to 16 decimal (which is the
MdePkg default too), yielding 32 + 16 * (16 + 8 + 8) == 544 bytes.
Regarding the lifecycle of the new area:
(a) when and how it is initialized after first boot of the VM
The library linked into SecMain finds that the area lacks the signature.
It initializes the signature, plus the rest of the structure. This is
independent of S3 support.
Consumption of the area is also limited to SEC (but consumption does
depend on full-config-boot).
(b) how it is protected from memory allocations during DXE
It is not, in the general case; and we don't need to. Nothing else links
against BaseExtractGuidedSectionLib; it's OK if DXE overwrites the area.
(c) how it is protected from the OS
When S3 is enabled, we cover it with AcpiNVS in InitializeRamRegions().
When S3 is not supported, the range is not protected.
(d) how it is accessed on the S3 resume path
Examined by the library linked into SecMain. Registrations update the
table in-place (based on GUID matches).
(e) how it is accessed on the warm reset path
If S3 is enabled, then the OS won't damage the table (due to (c)), hence
see (d).
If S3 is unsupported, then the OS may or may not overwrite the
signature. (It likely will.) This is identical to the pre-patch status.

This driver (from
"MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf")
is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely
as a form of notification), the driver reloads itself to reserved memory.
During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.
The boot script is transferred internal to PiDxeS3BootScriptLib:
Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.

"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.
S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.
The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.
PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.

The S3 suspend/resume infrastructure depends on the LockBox library class.
The edk2 tree currently contains Null and SMM instances. The Null instance
is useless, and the SMM instance would require SMM emulation by including
the SMM core and adding several new drivers, which is deemed too complex.
Hence add a simple LockBoxLib instance for OVMF.

This driver will support a flash FVB implementation if QEMU flash
is detected.
The driver is added to the apriori list to make sure it runs
before the EmuVariableFvbRuntimeDxe driver. If this driver detects
flash support, then it will disable the EmuVariableFvbRuntimeDxe
driver by setting PcdFlashNvStorageVariableBase64.

This is to prepare for QEMU flash support which will allow
non-volatile variables to be saved in the flash image.
Note two size changes:
* NV Varstore size increased from 0xc000 to 0xe000
* FTW work size decreased from 0x2000 to 0x1000
The reason for this change is that the fault-tolerant write
support requires that the work area fit within the block
just before the fault-tolerant write spare storage blocks.
Since QEMU flash blocks have a size of 0x1000, this means
that the maximum FTW work size is 0x1000.
v2:
* Update commit message and PcdVariableStoreSize

The 1MB image with full debug and the shell included is too
large to implement flash based non-volatile variable.
After this change, building with -D FD_SIZE_1MB will
force the smaller flash size.
The default size for RELEASE build remains at 1MB, so using
-b RELEASE on the build command line will result in a
1MB flash size. For RELEASE builds -D FD_SIZE_2MB can be
used to produce a 2MB flash image.

Now we will build and use the UEFI shell (ShellPkg) instead.

DHCP, PXE, and StdLib socket apps are enabled in OVMF by the sum of:
(a) a UEFI NIC driver,
(b) the generic network stack.
The only choice for (a) used to be the proprietary Intel E1000 driver,
which is cumbersome to obtain and enable.
The iPXE UEFI NIC drivers packaged with qemu-1.5 cover (a) for each NIC
type supported by qemu, and are easy to obtain & configure, even for
earlier qemu versions. Therefore enable (b) per default as well.
This doesn't take up much space; the binaries (b) adds to the firmware
don't seem to need -D FD_SIZE_2MB.
Intel's e1000 driver remains an option, requested by the -D E1000_ENABLE
build flag.

With reference to
<http://sourceforge.net/mailarchive/message.php?msg_id=30359322>:
"MEMFD is built so MAINFV's contents will be relocated during the build to
address 0x800000", and it "is a firmware volume with most OVMF code/data
uncompressed. [...] Increasing its size has a little impact on the size of
the resulting firmware image since the blank part of the firmware volume
will compress well."
Let's increase the size to 8MB, since the current limit can get in the way
(for example when building-in the Intel3.5 drivers for e1000 with
-D FD_SIZE_2MB -D NETWORK_ENABLE -D SECURE_BOOT_ENABLE).
