__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among

Read Disk does a modification of ExtMbrStartingLba with the code MultU64x32
(ExtMbrStartingLba, BlockSize) Error detection to see if ExtMbrStartingLBA
has a value of 0. This is invalid as LBA 0 = MBR. After modification, the
next time ExtMbrStartingLba is in this function if ExtMbrStartingLba is set
to 0 in the MBR it never passes the while/do evaluation It is multiplied by
0 by read disk , set to 0 by an invalid MBR and goes back to evaluation
This condition will also cause Ws19 and WS22 to hang, however Microsoft has
developed a hotfix patch that will be released in 2022

This patch initializes the linked list RegisteredRamDisks in
RamDiskDxeEntryPoint before the registration of gEfiRamDiskProtocolGuid
with InstallMultipleProtocolInterfaces, allowing ramdisks to be created
via a callback installed with RegisterProtocolNotify as soon as the

Without this, calling RamDisk->Register() in the callback causes a crash:

Per UEFI Spec 2.8 (UEFI_Spec_2_8_final.pdf, page 114)
5.2.3 Protective MBR
Table 20. Protective MBR Partition Record protecting the entire disk
The description for BootIndicator states the following:
> Set to 0x00 to indicate a non-bootable partition. If set to any
> value other than 0x00 the behavior of this flag on non-UEFI
> systems is undefined. Must be ignored by UEFI implementations.
Unfortunately, we have been incorrectly assuming that the
BootIndicator value must be 0x00, which leads to problems
when the 'pmbr_boot' flag is set on a disk containing a GPT
(such as with GNU parted). When the flag is set, the value
changes to 0x01, causing this check to fail and the system
is rendered unbootable despite it being valid from the
perspective of the UEFI spec.
To resolve this, we drop the check for the BootIndicator
so that we stop caring about the value set there, which
restores the capability to boot such disks.

The patch to fix LBA size would cause a regression that make the
partition of CD image with media type other than NO_EMULATOR unobserved.
The patch used to fix the CD image's MBR table issue. The CD MBR
table would always be ignored because it would be handled by the

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823
Refer to UEFI spec 2.8, Section 13.3.2, a block device should
be scanned as below order:
1. GPT
2. ISO 9660 (El Torito) (UDF should aslo be here)
3. MBR
4. no partition found
Note: UDF is using the same boot method as CD, so put it in
the same priority with ISO 9660.
This would also solve the issue that ISO image with MBR would
be treat as MBR device instead of CD/DVD. That would make the
behavior of the image boot different:
If the CD/DVD's MBR be handled correctly, it would be enumerated
as a bootable device with MBR path and FAT filesystem. Some Linux
Distributions boot from such path (FAT with MBR path for ISO) would
come into the grub console instead of the installation selection.
With this change, the CD/DVD would always be enumerated with CD path.
And it would always boot to the installation selection.

The partition binding driver would run serval times during BDS.
If the partition support MBR, it would pass the first connection
in MBR partition child handler. The second connect for the same
device would return already started which would be treated as
not found. And it would continue to run next partition child
handler check. That is incorrect behavior to do next check if one
of the routine functions is passed. It may cause one device
installed serval partition child handle on it.
So treat the EFI_ALREADY_STARTED as EFI_SUCCESS to avoid incorrect
next partition child handle check.

Refer to
http://manpages.ubuntu.com/manpages/bionic/man8/mkudffs.8.html.
Some Linux ISOs may have the MBR table for compatibility reasons
for Windows. The MBR tale would contain the partition entry with
start LBA0 and whole media size. There are two methods to check
the filesystem in the CD-ROM:
1. MBR partition check (Windows)
2. Whole disk check (MAC OS)
UEFI doesn't have the MBR check for UDF and Eltorito. But it may
pass the MBR check for such table and fail to detect the filesystem
of UDF. Skip the MBR check if the MBR is added for Windows
compatiblity so that the partition driver can continue UDF and
ElTorito check.

PartitionValidMbr function's second parameter should be the
last sector of the device. For MBR partition, the block size is
sector size, i.e. 512 bytes. The original value is media block
last LBA which is counted by the media block size. And media
block size is not always 512 bytes, it may be larger which would
cause the MBR boundary check incorrect. The boundary check is
based on the partition entry start LBA and size of LBA which
are both counted by the sector number (512 bytes).

This commit will add an additional check within function GetPdFromLongAd()
when getting a Partition Descriptor from given a Long Allocation
Descriptor.
According to UDF 2.60 Spec, Section 2.2.13:
> The partition reference numbers used are determined by the order of the
> Partition Maps in the LVD.
(Also the picture comes before the above contents)
And a more detailed explanation of the partition reference numbers is at
https://sites.google.com/site/udfintro/ (seems not a formal documentation
though), Section 5.3.6.
Based on the above findings, the 'PartitionReferenceNumber' field in a
Long Allocation Descriptor is used as an index to access the Partition
Maps data within a Logical Volume Descriptor.
Hence, the new check focuses on the validity of this
'PartitionReferenceNumber' field in a Long Allocation Descriptor. Since
the current implementation of UdfDxe driver supports only one partition on
a Logical Volume, so the value of 'PartitionReferenceNumber' should be 0.

return EFI_UNSUPPORTED;
This commit will add "ASSERT (FALSE);" before the above line to indicate
this and thus matching the function description comments.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1249
We found potential dead codes within File.c during the code coverage test.
After manual review, we think the below ones are positive reports:
A. In function UdfRead():
else if (IS_FID_DELETED_FILE (Parent->FileIdentifierDesc)) {
Status = EFI_DEVICE_ERROR;
}
A File Identifier Descriptor will be get from the UDF media only by
function ReadDirectoryEntry(). And within this function, all the File
Identifier Descriptor with 'DELETED_FILE' characteristics will be skipped
and will not be returned. Hence, the above codes in function UdfRead()
will never be hit.
This commit will add "ASSERT (FALSE);" before the above line to indicate
this.

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.

The call in ProbeMediaStatusEx() to the ReadDisk() function of the
EFI_DISK_IO_PROTOCOL interface implemented in DiskIoDxe/DiskIo.c
crashed in DiskIo2ReadWriteDisk() because of the NULL value of
the destination buffer pointer.
Pass the address of a buffer in the stack instead of a NULL
pointer.
The similar fix was applied to ProbeMediaStatus in commit
df473cc1fc9acd1a623ec7e05276f2f0635c19d2
* MdeModulePkg/PartitionDxe: Fix media probe

In function FindFileEntry():
Instead of using the function parameter 'FileEntry', use a local
variable to store the buffer allocated for disk read operation.
For the below calling stack:
UdfOpenVolume() -> FindRootDirectory() -> FindFileEntry()
In FindFileEntry(), the call to 'DiskIo->ReadDisk()' is possible (e.g.
media change for a CD/DVD ROM device) to trigger a re-install of the
BlockIO(2) protocol which will further lead to a call of the BindingStop()
& BingdingStart() of the UdfDxe driver.
Meanwhile, for the above listed calling stack, the '**FileEntry'
parameter passed into FindFileEntry() is '&PrivFsData->Root'. 'PrivFsData'
is a driver-managed private data, it will be freed in BindingStop() and
re-allocate in BingdingStart().
In such case, if '*FileEntry' is used to store the allocated buffer, the
information will be lost if 'DiskIo->ReadDisk()' triggers a re-install of
the BlockIO(2) protocol. The subsequent call of the FreePool API:
FreePool (*FileEntry);
will cause issues.
This commit uses a local variable to store the allocated buffer.
