Shenglei Zhang 357fc11c35 MdeModulePkg/EbcDebugger: Use AsciiCharToUpper and CharToUpper
InternalUnicodeToUpper and InternalAsciiToUpper are internal functions,
so they are substituted by public functions AsciiCharToUpper and CharToUpper.
And their implements are removed.

Shenglei Zhang cecbecb71d MdeModulePkg/EbcDebugger: Change function names
Change UnicodeToUpper to InternalUnicodeToUpper.
Change AsciiToUpper to InternalAsciiToUpper.
These changes are committed for bisectability, or build failure will
occur when 2/7 is applied. Because the introduced function names in
2/7 are the same as ones in EdbSupporting.c.

Star Zeng 7cd6995946 MdeModulePkg Variable: Add emulated variable NV mode support
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1323
Merge EmuVariable and Real variable driver.

Add emulated variable NV mode support in real variable driver.
Platform can configure PcdEmuVariableNvModeEnable statically
(build time) or dynamically (boot time) to support emulated
variable NV mode.

If PcdEmuVariableNvModeEnable is configured to dynamic, its
value should be set before Variable driver starts to work,
otherwise default value will take effect.

Then EmuVariableRuntimeDxe could be removed, the removal of
EmuVariableRuntimeDxe will be done after platforms are migrated
to use the merged variable driver.

To meet with this usage, 64bit DynamicEx PcdVpdBaseAddress64 is introduced.
If its value is not zero, it will be used.
If its value is zero, static PcdVpdBaseAddress will be used.
When NON SPI platform enables VPD PCD, they need to set PcdVpdBaseAddress64.

Hao Wu 27b9cb33e7 MdeModulePkg/UdfDxe: Memory free/use after free in ResolveSymlink()
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1279

For function ResolveSymlink(), the below codes:

    if (CompareMem ((VOID *)&PreviousFile, (VOID *)Parent,
                    sizeof (UDF_FILE_INFO)) != 0) {
      CleanupFileInformation (&PreviousFile);
    }

    CopyMem ((VOID *)&PreviousFile, (VOID *)File, sizeof (UDF_FILE_INFO));

If the contents in 'PreviousFile' and 'File' are the same, call to
"CleanupFileInformation (&PreviousFile);" will free the buffers in 'File'
as well. This will lead to potential memory double free/use after free
issues.

This commit will add additional check to address the above issue.

Dandan Bi 979b7d802c MdeModulePkg/HiiDB: Make sure database update behaviors are atomic

When update contents in HiiDatabase, like:
1. Add/update/remove package list
2. Add/update string
3. Add/update image
We should make these operations atomic to prevent the
potential issue that the one update operation with
higher TPL may interrupt another.
This commit is to make the HiiDatabase update behaviors
atomic by adding EfiAcquireLock/EfiReleaseLock function.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1235

Function "HiiGetConfigurationSetting" may be called
when HiiDatabase contents have been updated.
And it is just to call function "HiiGetDatabaseInfo" to
get the contents in HiiDatabase and call function
"HiiGetConfigRespInfo" and get the configuration response
string form HII drivers.

So here we can remove function "HiiGetConfigurationSetting"
and make caller to call "HiiGetDatabaseInfo" and
"HiiGetConfigRespInfo" directly.

And thus it also can distinguish which code blocks are to
operate HiiDatabase contents and which code blocks are not.
Then it's easy to know which code blocks should be atomic
when updating HiiDatabase contents.

For function ReadFile():

If the line

  Status = GetAedAdsData (

is reached multiple times during the 'for' loop, freeing the data pointed
by variable 'Data' may potentially lead to variable 'Ad' referencing the
already-freed data.

After calling function GetAllocationDescriptor(), 'Data' and 'Ad' may
point to the same memory (with some possible offset). Hence, this commit
will move the FreePool() call backwards to ensure the data will no longer

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.

'RecordingFlags' can only with value 'LongAdsSequence' or
'ShortAdsSequence'. Moreover, this is also mentioned in the function
