Hao Wu 01a68fd37e MdeModulePkg/PartitionDxe: Merge the discovery of ElTorito into UDF
In order to create all of the children (El Torito standard and UDF) for
a CD/DVD media in an entry of the PartitionDriverBindingStart(), this
commit merges the discovery of the El Torito feature
(PartitionInstallElToritoChildHandles) into function
PartitionInstallUdfChildHandles.

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.

Paulo Alcantara baaa3cee1e MdeModulePkg/UDF: Fix creation of UDF logical partition
Do not reserve entire block device size for an UDF file system -
instead, reserve the appropriate space (UDF logical volume space) for
it.

Additionally, only create a logical partition for UDF logical volumes
that are currently supported by EDK2 UDF file system implementation. For
instance, an UDF volume with a single LVD and a single Physical (Type 1)
Partition will be supported.

Laszlo Ersek b4e5807d24 MdeModulePkg/PartitionDxe: remove always false comparison
In the expression

  (RemainderByMediaBlockSize != 0 ||
   Media->BlockSize > UDF_LOGICAL_SECTOR_SIZE)

the second expression is only evaluated if the first expression is false.

If the first expression is false, i.e.,

  RemainderByMediaBlockSize == 0

then UDF_LOGICAL_SECTOR_SIZE is a whole multiple of "Media->BlockSize",
which implies

  UDF_LOGICAL_SECTOR_SIZE >= Media->BlockSize.

Therefore whenever

  Media->BlockSize > UDF_LOGICAL_SECTOR_SIZE

is evaluated, it is false.

The expression

  ((expression) || FALSE)

is equivalent to

  (expression).

Laszlo Ersek b19aeeb91e MdeModulePkg/PartitionDxe: don't divide 64-bit values with C operators
In edk2, the division and shifting of 64-bit values are forbidden with
C-language operators, because the compiler may generate intrinsic calls
for them.

For example, clang-3.8 emits a call to "__umoddi3" for

  UDF_LOGICAL_SECTOR_SIZE % Media->BlockSize

in PartitionInstallUdfChildHandles(), if PartitionDxe is built for IA32,
which then fails to link.

UDF_LOGICAL_SECTOR_SIZE has type UINT64, while
EFI_BLOCK_IO_MEDIA.BlockSize has type UINT32(). Replace the % operator
with a DivU64x32Remainder() call.

Hao Wu e33257215b MdeModulePkg PartitionDxe: Add Re-entry handling logic for BindingStop
There are scenario when the BindingStop service of PartitionDxe driver be
re-entered.

An example will be ejecting a DVD from a SATA DVDROM and then run
"reconnect -r" under shell. In this specific case, part of the calling
stack will be:

PartitionDriverBindingStop() (PartitionDxe) ->
Stop first child handle (PartitionDxe) ->
ScsiDiskFlushBlocksEx() (ScsiDiskDxe) ->
A media change is detected (ScsiDiskDxe) ->
Reinstall of BlockIO(2) protocols (ScsiDiskDxe) ->
Entering PartitionDriverBindingStop() again (PartitionDxe) ->
Potential risk of referencing already stopped child handle (PartitionDxe)
...

The current code has potential issue of referencing of already stopped
child handle. This commit adds re-entry handling logic to resolve such
issue.

Ronald Cron df473cc1fc MdeModulePkg/PartitionDxe: Fix media probe
The call in ProbeMediaStatus() 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.

In addition to avoiding the crash, that way, the media probe does not
depend anymore on the way the EFI_DISK_IO_PROTOCOL implementation deals
with a NULL value of the destination buffer pointer as the UEFI
specification does not specify the expected behaviour.

vanjeff 9be2900668 1. updated "the Bus Driver that creates all of its child handles on the first call to Start()" not to create any child handle if RemainingDeviepath is the End of Device Path Node, per UEFI 2.3.
The others changes include:
a. Check RemainingDevicePath at beginning of Supported(), make sure it has been verified before Start() is called.
b. Check IO protocol firstly rather than EfiDevicePathProtocolGuid, reduce the times entering into Start() function because EfiDevicePathProtocolGuid existed on most of handle.

2. roll back serial drivers not to create child device, if the device speicifed by remainingdevicepath cannot find in the created devices list.

eric_tian 15a865075c Roll back the change in Partition driver. currently we enhance the EHCI driver to guarantee that the EHCI controller get attached to the EHCI controller before the UHCI driver attaches to the UHCI controller. This way can avoid the case happen that UHCI sees the disconnect and EHCI sees the connect event due to the control transfer in shared port. It may cause Partition.Start to be interrupted by Partition.Stop.

eric_tian c8148ea20d if Usb mass storage interface returns EFI_DEVICE_ERROR, we should jump out the loop which is used to determine if the current block device supports GPT/Torito/MBR in Partition driver. This way can avoid Partition.start is interrupted by itself Partition.stop().
