Zhichao Gao f82b827c92 Revert "MdeModulePkg/PartitionDxe: Fix the incorrect LBA size in child ..."
This reverts commit e0eacd7daa.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3012

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
Eltorito partition handler first and never go into the MBR handler.
So directly revert it.

Zhichao Gao e0eacd7daa MdeModulePkg/PartitionDxe: Fix the incorrect LBA size in child hander
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2843

PartitionInstallChildHandle's parameters Start and End is counted
by the BlockSize, but in the implementation it uses the parent
device's BlockSize to calculate the new Start, End and LastBlock.
It would cause the driver report incorrect block scope and the file
system would fail to be found with right block scope.
So correct it to the right value.

Zhichao Gao 94b7df5c4a MdeModulePkg/PartitionDxe: Revert changes for the special MBR
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823

Revert "MdeModulePkg/PartitionDxe: Skip the MBR that add for CD-ROM"

Follow the spec definition, the ISO 9660 (and UDF) would be
checked before the MBR. So it is not required to skip such
MBR talbe that contian the entire block device.

Zhichao Gao f0f7140150 MdeModulePkg/PartitionDxe: Put the UDF check ahead of MBR
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.

Zhichao Gao c7195b9ec3 MdeModulePkg/PartitionDxe: Add already start check for child hanldes
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823

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.

Zhichao Gao e906346dcb MdeModulePkg/PartitionDxe: Skip the MBR that add for CD-ROM
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823

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.

Zhichao Gao a35de0aff3 MdeModulePkg/PartitionDxe: Correct the MBR last block value
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823

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).

Hao Wu 85acb5e8ff MdeModulePkg/UdfDxe: Add more check when getting PD from LongAd
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1254

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.

- 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

- stale SHELL_FILE_HANDLE reference in a comment.

Hao Wu 7a96634889 MdeModulePkg/UdfDxe: Avoid possible loss track of allocated buffer
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.

Paulo Alcantara 1fbe8276c4 MdeModulePkg/PartitionDxe: Fix UDF fs access on certain CD/DVD medias
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=725

Historically many drives or medias do not correctly return their value
for block N - which is also referred as last addressable/recorded block.
When they do so, there is still a problem when relying on last recorded
block number returned by SCSI commands READ CAPACITY and READ TRACK
INFORMATION - that is, between block 0 and block N there may be
unwritten blocks which are located outside any track.

That said, the Partition driver was unable to find AVDP at block N on
certain medias that do not either return or report their last recorded
block number correctly.

Apparently there is no official or correct way to find the correct block
number, however tools like the Philips UDF Conformance Tool (udf_test)
apply a correction by searching for an AVDP or VAT in blocks N through
N-456 -- this can be observed by looking at the log reported by udf_test
on those CD/DVD medias. So, if the AVDP or VAT is found, then it sets
the last recorded block number to where AVDP or VAT was located.

With the below setence in UDF 2.60, 6.13.2.2 Background Physical
Formatting:

"... the second AVDP must be recorded after the Background physical
Formatting has been finished..."

Implies that the last recorded block is the one where second AVDP was
recorded.

This patch implements a similar way to correct the last recorded block
number by searching for last AVDP in blocks N-1 through N-512 on those
certain medias, as well as ensure a minimum number of 2 AVDPs found as
specified by ECMA 167 and UDF 2.60 specifications.
