Ruiyu Ni 5fc3889bb3 MdeModulePkg/DxeCore: Avoid accessing non-owned memory
The patch fixes two kinds of bugs in DxeCore that accesses memory
which might be freed or owned by other modules.
The two bugs don't cause functionality issue.

1. CoreValidateHandle() checks whether the handle is valid by
   validating its signature. The proper way is to check whether
   the handle is in the handle database.
2. CoreDisconnectControllersUsingProtocolInterface() and
   CoreOpenProtocol() de-reference Link pointer which is
   already freed. The proper way is to not de-reference the pointer.

Star Zeng c01f13d52a MdeModulePkg: Enhance the debug message for InstallProtocolInterface
Current code is using debug message like below for
InstallProtocolInterface.
InstallProtocolInterface: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX XXX

User could not know whether the installation is failed or not by the
debug message, for example, the code below does not initialize Handle
before calling InstallProtocolInterface, EFI_INVALID_PARAMETER will be
returned.
  EFI_HANDLE Handle;
  Status = gBS->InstallProtocolInterface (

                  EFI_NATIVE_INTERFACE,
                  XXX
                  );

This patch is to add additional debug message if the installation
is failed and specific debug message for the case that the input
handle is invalid.

Shi, Steven 322d827c0f MdeModulePkg: Fix use-after-free error in InstallConfigurationTable()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=601

When installing configuration table and the original
gDxeCoreST->ConfigurationTable[] buffer happen to be not big enough to
add a new table, the CoreInstallConfigurationTable() enter the branch
of line 113 in InstallConfigurationTable.c to free the old
gDxeCoreST->ConfigurationTable[] buffer and allocate a new bigger one.
The problem happens at line 139 CoreFreePool(), which is to free the
old gDxeCoreST->ConfigurationTable[] buffer. The CoreFreePool()'s
behavior is to free the buffer firstly, then call the
InstallMemoryAttributesTableOnMemoryAllocation (PoolType) to update
the EfiRuntimeServices type memory info, the
CoreInstallConfigurationTable() will be re-entered by CoreFreePool()
in its calling stack, then use-after-free read error will happen at
line 59 of InstallConfigurationTable.c and use-after-free write error
will happen at line 151 and 152 of InstallConfigurationTable.c.

The patch is to update System table to the new table pointer before
calling CoreFreePool() to free the old table.

The case above is in DxeCore, but not in PiSmmCore.
The change in PiSmmCore is to be consistent with DxeCore.

Ard Biesheuvel 5920a9d16b MdeModulePkg/MemoryProtection: split protect and unprotect paths
Currently, the PE/COFF image memory protection code uses the same code
paths for protecting and unprotecting an image. This is strange, since
unprotecting an image involves a single call into the CPU arch protocol
to clear the permission attributes of the entire range, and there is no
need to parse the PE/COFF headers again.

So let's store the ImageRecord entries in a linked list, so we can find
it again at unprotect time, and simply clear the permissions.

Note that this fixes a DEBUG hang on an ASSERT() that occurs when the
PE/COFF image fails to load, which causes UnprotectUefiImage() to be
invoked before the image is fully loaded.

Ard Biesheuvel 3f2ae009ec MdeModulePkg/DxeCore: deal with allocations spanning several memmap entries
When attempting to perform page allocations using AllocateAddress, we
fail to check whether the entire region is free before splitting the
region. This may lead to memory being leaked further into the routine,
when it turns out that one of the memory map entries intersected by the
region is already occupied. In this case, prior conversions are not rolled
back.

For instance, starting from this situation

0x000040000000-0x00004007ffff [ConventionalMemory ]
0x000040080000-0x00004009ffff [Boot Data          ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]

a failed EfiLoaderData allocation @ 0x40000000 that covers the BootData
region will fail, but leave the first part of the allocation converted,
so we end up with

0x000040000000-0x00004007ffff [Loader Data        ]
0x000040080000-0x00004009ffff [Boot Data          ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]

even though the AllocatePages() call returned an error.

So let's check beforehand that AllocateAddress allocations are covered
by a single memory map entry, so that it either succeeds or fails
completely, rather than leaking allocations.

Hao Wu 16f6922709 MdeModulePkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Ard Biesheuvel 7eb927db3e MdeModulePkg/DxeCore: implement memory protection policy
This implements a DXE memory protection policy that ensures that regions
that don't require executable permissions are mapped with the non-exec
attribute set.

First of all, it iterates over all entries in the UEFI memory map, and
removes executable permissions according to the configured DXE memory
protection policy, as recorded in PcdDxeNxMemoryProtectionPolicy.

Secondly, it sets or clears the non-executable attribute when allocating
or freeing pages, both for page based or pool based allocations.

Note that this complements the image protection facility, which applies
strict permissions to BootServicesCode/RuntimeServicesCode regions when
the section alignment allows it. The memory protection configured by this
patch operates on non-code regions only.

Jiewen Yao d0e92aad46 MdeModulePkg/DxeCore: Add UEFI image protection.
If the UEFI image is page aligned, the image code section is set to read
only and the image data section is set to non-executable.

1) This policy is applied for all UEFI image including boot service driver,
runtime driver or application.
2) This policy is applied only if the UEFI image meets the page alignment
requirement.
3) This policy is applied only if the Source UEFI image matches the
PcdImageProtectionPolicy definition.
4) This policy is not applied to the non-PE image region.

The DxeCore calls CpuArchProtocol->SetMemoryAttributes() to protect
the image. If the CpuArch protocol is not installed yet, the DxeCore
enqueues the protection request. Once the CpuArch is installed, the
DxeCore dequeues the protection request and applies policy.

Once the image is unloaded, the protection is removed automatically.

The UEFI runtime image protection is teared down at ExitBootServices(),
the runtime image code relocation need write code segment at
SetVirtualAddressMap(). We cannot assume OS/Loader has taken over
page table at that time.

NOTE: It is per-requisite that code section and data section
should not be not merged. That is same criteria for SMM/runtime driver.

We are not able to detect during BIOS boot, because
we can only get LINK warning below:
"LINK : warning LNK4254: section '.data' (C0000040) merged into
'.text' (60000020) with different attributes"
But final attribute in PE code section is same.

Liming Gao 733c0c88c3 MdeModulePkg: Remove NORETURN for PeiCore() and DxeMain() function
PeiCore EntryPoint library _ModuleEntryPoint() will call PeiCore(), then call
CpuDeadLoop (). When NORETURN is added for PeiCore(), MSVC compiler will report
warning C4702: unreachable code for CpuDeadLoop (). And, the warning is treated
as error and cause build break. DxeMain() has the similar issue.

edk2 uses EntryPoint library to wrap every module entry point function except
for SEC. The module entry point is still called by _ModuleEntryPoint(). So,
there will be negative impact to add NORETURN for the module entry point.

Jiewen Yao 0ab90add0f MdeModulePkg-DxeCore: rename CoreGetMemoryMapPropertiesTable
This patches rename CoreGetMemoryMapPropertiesTable to
CoreGetMemoryMapWithSeparatedImageSection.

The reason is that CoreGetMemoryMapPropertiesTable is called
by MemoryAttributesTable.c to get separated PE image section
information.

It is confusing to use *PropertiesTable, because it is NOT
related to PropertiesTable.c

We rename it to avoid confusing.

Liming Gao 467d5f6b30 MdeModulePkg: DxeCore MemoryPool Algorithm Update
Use 128 bytes as the start size region to be same to previous one.

64 bytes is small as the first range. On X64 arch, POOL_OVERHEAD
takes 40 bytes, the pool data less than 24 bytes can be fit into
it. But, the real allocation is few that can't reduce its free pool
link list. And, the second range (64~128) has more allocation
that also increases the free pool link list of the first range.
Then, the link list will become longer and longer. When LinkList
check enable in DEBUG tip, the long link list will bring the
additional overhead and bad performance. Here is the performance
data collected in our X64 platform with DEBUG enable.
64  byte: 22 seconds in BDS phase
128 byte: 19.6 seconds in BDS phase

Ruiyu Ni ae6945b61b MdeModulePkg/DxeCore: Avoid assertion in CoreLocateProtocol
The patch uses CoreAcquireLockOrFail() instead of
CoreAcquireProtocolLock() in CoreLocateProtocol() to avoid
assertion when CoreLocateProtocol() is called with the
protocol database locked.

The issue was found when changing PcdDebugPrintErrorLevel to
enable page/pool allocation debug message.
Nt32 platform hangs immediately after DxeCore is loaded.
Investigation shows the following calling stacks:

DxeCore entry point (Install a certain protocol)
0 DxeCore::CoreInstallProtocolInterface  // Protocol DB is locked
1 DxeCore::AllocatePool
2 PeiDxeDebugLibReportStatusCode::DebugPrint
3 DxeReportStatusCodeLib::ReportStatusCodeEx // <-------------------|
4 DxeReportStatusCodeLib::InternalGetReportStatusCode               |
5 DxeCore::LocateProtocol(StatusCodeRuntimeProtocol)                |
                     // Assertion when locking Protocol DB 2nd time |
6 DxeCore::CoreAcquireProtocolLock                                  |
7 PeiDxeDebugLibReportStatusCode::DebugAssert                       |
8 DxeReportStatusCodeLib::ReportSatusCodeEx  // loop begins ---------

In frame #6 the assertion is triggered due to the protocol database
is already locked. #8 calls #4 and the loop begins.
After changing #6 to CoreAcquireLockOrFail(), the assertion is
avoided and the loop is broken.

With the fix, NT32 can boot to Shell even setting
PcdDebugPrintErrorLevel to 0xFFFFFFFF, with all error levels turned
on.

To make sure the correctness of MemoryAttributesTable, this patch is
to enhance MemoryAttributesTable installation to install

to make sure it is at the last of ReadyToBoot event, and also hook
runtime memory allocation after ReadyToBoot.
