Hao Wu 5317e9ccaf MdeModulePkg/UdfDxe: Handle dead codes in FileSystemOperations.c
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. For function GetAllocationDescriptor():
Due to the all the calling places for this function, the input parameter
'RecordingFlags' can only with value 'LongAdsSequence' or
'ShortAdsSequence'. Moreover, this is also mentioned in the function
description comments for GetAllocationDescriptor().

So the below code will never be reached:

  return EFI_DEVICE_ERROR;

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

B. For function GetAllocationDescriptorLsn():
Due to the all the calling places for this function, the input parameter
'RecordingFlags' can only with value 'LongAdsSequence' or
'ShortAdsSequence'. Moreover, this is also mentioned in the function
description comments for GetAllocationDescriptorLsn().

So the below code will never be reached:

  return EFI_UNSUPPORTED;

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

Hao Wu 11941d3b1b MdeModulePkg/UdfDxe: Handle dead codes in File.c
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.

- bogus "FileHandle = NULL" assignments,
- passing a potentially unaligned "FILEPATH_DEVICE_PATH.PathName" field to

- leaking "Handle1" when the device path type/subtype check fails in the

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.

Paulo Alcantara 11b4463e09 MdeModulePkg/UdfDxe: Fix NULL pointer dereference
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=704

For root directory, the FID (File Identifier Descriptor) pointer is
accessible through PRIVATE_UDF_FILE_DATA.Root, whereas non-root
directory and regular files, their FIDs are accessible through
PRIVATE_UDF_FILE_DATA.File.

In UdfSetPosition(), the FID was retrieved through
PRIVATE_UDF_FILE_DATA.File, hence when calling it with a root directory,
PRIVATE_UDF_FILE_DATA.File.FileIdentifierDescriptor would be NULL and
then dereferenced.

This patch fixes the NULL pointer dereference by calling _FILE() to
transparently return the correct UDF_FILE_INFO * which points to a valid
FID descriptor of a specific file.

Laszlo Ersek 5afa5b8159 MdeModulePkg/UdfDxe: suppress incorrect compiler warning in ReadFile()
When building the driver for DEBUG/RELEASE, GCC48/GCC49 warn about
ReadFile() possibly using "BytesLeft" without initializing it first.

This is not the case. The reads of "BytesLeft" are only reachable if
(ReadFileInfo->Flags == READ_FILE_SEEK_AND_READ). But, in that case, we
also set "BytesLeft" to "ReadFileInfo->FileDataSize", near the top of the
function.

Assign "BytesLeft" zero at the top, and add a comment that conforms to the
pending Coding Style Spec feature request at
<https://bugzilla.tianocore.org/show_bug.cgi?id=607>.

This issue was reported by Ard's and Gerd's CI systems independently.

Laszlo Ersek 998aee899e MdeModulePkg/UdfDxe: reject reserved values in ICB.Flags[2:0]
The ECMA-167 standard (3rd Edition, June 1997) reserves values 4 through 7
in the ICB.Flags[2:0] bit-field for future standardization; see "14.6 ICB
Tag" / "14.6.8 Flags (RBP 18)".

https://www.ecma-international.org/publications/standards/Ecma-167.htm

The

  switch (RecordingFlags)

statement in the ReadFile() function handles all the standard values,
using the constants of the UDF_FE_RECORDING_FLAGS enum type. However, the
reserved values are not caught with a "default" case label, which both
breaks the edk2 Coding Style Spec, and leaves the Status variable
un-initialized, before we return Status under the Done label.

Set Status to EFI_UNSUPPORTED if we encounter a reserved value.

This issue was reported by Ard's and Gerd's CI systems independently
(through build failures with GCC48/GCC49, DEBUG/RELEASE targets).

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.

Ard reports that clang-3.8 correctly flags the following issue in the
ReadFile() function:

If "RecordingFlags" is INLINE_DATA, then there are three paths through the
code where we mean to return success, but forget to set Status
accordingly:

(1) when "ReadFileInfo->Flags" is READ_FILE_GET_FILESIZE, or

(2) when "ReadFileInfo->Flags" is READ_FILE_ALLOCATE_AND_READ and
    AllocatePool() succeeds, or

(3) when "ReadFileInfo->Flags" is READ_FILE_SEEK_AND_READ.

Set "Status" to EFI_SUCCESS when we are done processing the INLINE_DATA
request, i.e., when we reach the corresponding "break" statament under the
INLINE_DATA case label.

Laszlo Ersek a3240c63ec MdeModulePkg/UdfDxe: ASSERT() valid ReadFileInfo Flags for INLINE_DATA req
In the ReadFile() function, if "RecordingFlags" is INLINE_DATA, then we
cover the following values of "ReadFileInfo->Flags":

- READ_FILE_GET_FILESIZE
- READ_FILE_ALLOCATE_AND_READ
- READ_FILE_SEEK_AND_READ

We don't do anything (just proceed to the end of the function) if
"ReadFileInfo->Flags" is anything else.

In reality the above three values cover the domain of the
UDF_READ_FILE_FLAGS enum type fully, and "ReadFileInfo->Flags" is only
ever set internally to UdfDxe. Therefore any other flag value would be a
bug in UdfDxe.

ASSERT() specifically that "ReadFileInfo->Flags" has been set correctly,
so that the reader is not left wondering what happens if none of the enum
constants match.
