Shenglei Zhang 316b3a719f MdeModulePkg: Remove PcdIdentifyMappingPageTablePtr
PcdIdentifyMappingPageTablePtr was used to share page
table buffer between modules.
Buf after some changes on 2015/07/17, it was useless
and could be removed.
https://bugzilla.tianocore.org/show_bug.cgi?id=1304

v2:
1.Remove PcdIdentifyMappingPageTablePtr in MdeModulePkg.uni.
2.Update the commit message.

Hao Wu bd224a5dad MdeModulePkg/NvmExpressPei: Refine data buffer & len check in PassThru
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1142

The fix is similar to commit ebb6c7633b.
We found that a similar fix should be applied to the NVMe PEI driver as
well. Hence, this one is for the PEI counterpart driver.

According to the the NVM Express spec Revision 1.1, for some commands
(like Get/Set Feature Command, Figure 89 & 90 of the spec), the Memory
Buffer maybe optional although the command opcode indicates there is a
data transfer between host & controller (Get/Set Feature Command, Figure
38 of the spec).

Hence, this commit refine the checks for the 'TransferLength' and
'TransferBuffer' field of the
EDKII_PEI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET structure to address this
issue.

Dandan Bi 8cd4e734cc MdeModulePkg/DisplayEngine: Remove useless NULL ptr check for NewPos
In function UiDisplayMenu, the NewPos ptr which used to point to the
highlight menu entry. It will always point to the menu entry which
need to be highlighted or the gMenuOption menu if the highlight menu
is not found.
So we can remove the NULL ptr check for NewPos in this function.
And add the ASSERT code to avoid if any false positive reports
of NULL pointer dereference issue raised from static analysis.

Jian J Wang 0adc6eae94 MdeModulePkg/Core: fix ineffective guard page issue
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1295

This issue originates from following patch which allows to enable
paging if PcdImageProtectionPolicy and PcdDxeNxMemoryProtectionPolicy
(in addition to PcdSetNxForStack) are set to enable related features.

  5267926134

Due to above change, PcdImageProtectionPolicy will be set to 0 by
default in many platforms, which, in turn, cause following code in
MdeModulePkg\Core\Dxe\Misc\MemoryProtection.c fail the creation of
notify event of CpuArchProtocol.

1138:  if (mImageProtectionPolicy != 0 ||
           PcdGet64 (PcdDxeNxMemoryProtectionPolicy) != 0) {
1139:  Status = CoreCreateEvent (
...
1142:             MemoryProtectionCpuArchProtocolNotify,
...
1145:             );

Then following call flow won't be done and Guard pages will not be
set as not-present in SetAllGuardPages() eventually.

   MemoryProtectionCpuArchProtocolNotify()
=> HeapGuardCpuArchProtocolNotify()
=> SetAllGuardPages()

The solution is removing the if(...) statement so that the notify
event will always be created and registered. This won't cause
unnecessary code execution because, in the notify event handler,
the related PCDs like

    PcdImageProtectionPolicy and
    PcdDxeNxMemoryProtectionPolicy

will be checked again before doing related jobs.

Jian J Wang 8a7ff892ca MdeModulePkg/Core: fill logic hole in MemoryProtectionCpuArchProtocolNotify
At the end of of MemoryProtectionCpuArchProtocolNotify there's cleanup
code to free resource. But at line 978, 994, 1005 the function returns
directly. This patch use "goto" to replace "return" to make sure the
resource is freed before exit.

1029:  CoreCloseEvent (Event);
1030:  return;

There's another memory leak after calling gBS->LocateHandleBuffer() in
the same function:

  Status = gBS->LocateHandleBuffer (
                  ByProtocol,
                  &gEfiLoadedImageProtocolGuid,
                  NULL,
                  &NoHandles,
                  &HandleBuffer
                  );

HandleBuffer is allocated in above call but never freed. This patch
will also add code to free it.

Ruiyu Ni bfc87aa78e MdeModulePkg/PiSmmIpl: Do not reset SMRAM to UC when CPU driver runs
Today's PiSmmIpl implementation initially sets SMRAM to WB to speed
up the SMM core/modules loading before SMM CPU driver runs.
When SMM CPU driver runs, PiSmmIpl resets the SMRAM to UC. It's done
in SmmIplDxeDispatchEventNotify(). COMM_BUFFER_SMM_DISPATCH_RESTART
is returned from SMM core that SMM CPU driver is just dispatched.

Since now the SMRR is widely used to control the SMRAM cache setting.
It's not needed to reset the SMRAM to UC anymore.

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.

Since the data buffer for EhcMonitorAsyncRequests is internal

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.

Jian J Wang 63ebde8ef6 MdeModulePkg/Core: add freed-memory guard feature
Freed-memory guard is used to detect UAF (Use-After-Free) memory issue
which is illegal access to memory which has been freed. The principle
behind is similar to pool guard feature, that is we'll turn all pool
memory allocation to page allocation and mark them to be not-present
once they are freed.

This also implies that, once a page is allocated and freed, it cannot
be re-allocated. This will bring another issue, which is that there's
risk that memory space will be used out. To address it, the memory
service add logic to put part (at most 64 pages a time) of freed pages
back into page pool, so that the memory service can still have memory
to allocate, when all memory space have been allocated once. This is
called memory promotion. The promoted pages are always from the eldest
pages which haven been freed.

This feature brings another problem is that memory map descriptors will
be increased enormously (200+ -> 2000+). One of change in this patch
is to update MergeMemoryMap() in file PropertiesTable.c to allow merge
freed pages back into the memory map. Now the number can stay at around
510.

Hao Wu 8411c9d5c4 MdeModulePkg/NvmExpressDxe: Refine PassThru IO queue creation behavior
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1260

For the PassThru() service of NVM Express Pass Through Protocol, the
current implementation (function NvmExpressPassThru()) will only use the
IO Completion/Submission queues created internally by this driver during
the controller initialization process. Any other IO queues created will
not be consumed.

So the value is little to accept external IO Completion/Submission queue
creation request. This commit will refine the behavior of function
NvmExpressPassThru(), it will only accept driver internal IO queue
creation commands and will return "EFI_UNSUPPORTED" for external ones.

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.
