Hao Wu 38c9fbdcaa MdeModulePkg/RamDiskDxe: Restrict on RAM disk size (CVE-2018-12180)
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1134

Originally, the block size of created Ram disks is hard-coded to 512
bytes. However, if the total size of the Ram disk is not a multiple of 512
bytes, there will be potential memory access issues when dealing with the
last block of the Ram disk.

This commit will adjust the block size of the Ram disks to ensure that the
total size is a multiple of the block size.

Laszlo Ersek 5b080845a1 MdeModulePkg/RamDiskDxe: replace OpenFileByDevicePath() with UefiLib API
Replace the OpenFileByDevicePath() function with EfiOpenFileByDevicePath()
from UefiLib, correcting the following issues:

- imprecise comments on OpenFileByDevicePath(),
- code duplication between this module and other modules,
- local variable name "EfiSimpleFileSystemProtocol" starting with "Efi"
  prefix,
- bogus "FileHandle = NULL" assignments,
- passing a potentially unaligned "FILEPATH_DEVICE_PATH.PathName" field to
  a protocol member function (forbidden by the UEFI spec),
- leaking "Handle1" when the device path type/subtype check fails in the
  loop,
- stale SHELL_FILE_HANDLE reference in a comment.

Laszlo Ersek 76874be3d4 MdeModulePkg/RamDiskDxe: fix C string literal catenation in info messages
RamDiskDxe installs the RamDiskAcpiCheck() Ready To Boot callback
function. If EFI_ACPI_TABLE_PROTOCOL and/or EFI_ACPI_SDT_PROTOCOL are not
found, then informational messages are logged, and the RAM disks are not
published to the (nonexistent) NFIT table.

The logic is fine, but the info messages are not concatenated correctly
from multiple string literals -- the second parts are passed as (unused)
arguments to DEBUG(). Fix the typos.

Hao Wu 5cf8a917bd MdeModulePkg RamDiskDxe: Do not save 'Size' numeric value by varstore
The 'Size' numeric value used when creating a raw RAM disk does not
require a varstore to save its previous value in the create raw RAM disk
HII page.

The expecting behavior is that after a user created a raw RAM disk, the
next time when the create raw RAM disk page is entered, the 'Size' numeric
will be the default value (EFI_PAGE_SIZE).

Hao Wu 09abc63675 MdeModulePkg RamDiskDxe: Fix wrong HII behavior for more than 8 RAM disks
The RamDiskDxe driver originally uses a variable-length HII varstore to
retrieve the HII checkbox status of each registered RAM disk.

However, HII does not support the variable-length varstore feature.
Therefore, only the checkbox status for the first 8 RAM disks are tracked
for the following definition of HII varstore structure considering the
alignment:

typedef struct {
  UINT64    Size;
  UINT8     RamDiskList[0];
  } RAM_DISK_CONFIGURATION;

This commit uses the private data of each registered RAM disks to track
the HII checkbox status instead to resolve the issue.

Hao Wu 07a3fecd4c MdeModulePkg RamDiskDxe: Report ACPI NFIT for reserved memory RAM disks
The RamDiskDxe now will report RAM disks with reserved memory type to NFIT
in the ACPI table.

This commit will also make sure that an NVDIMM root device exists in the
\SB scope before reporting any RAM disk to NFIT.

To properly report the NVDIMM root device, one will need to append the
following content in the [Rule.Common.DXE_DRIVER] field in platform FDF
files:

RAW ACPI  Optional                |.acpi
RAW ASL   Optional                |.aml
