Ard Biesheuvel 34a4ddda4d BaseTools/Conf: disable DTC legacy phandle format
By default, the device tree compiler emits phandle properties twice:
once called 'phandle' and again called 'linux,phandle'. Given that
Linux was updated in early 2010 [0] to accept the former (which is
what is specified in the ePAPR and device tree specifications), there
is no point in emitting both when compiling device trees for UEFI
platforms.

Ruiyu Ni 56658c22a6 MdePkg/SafeString: Fix potential out-of-bound memory access
Today's implementation of [Ascii]StrnCpyS/[Ascii]StrnCatS calls
StrnLenS () to get the length of source string but supplies the
destination buffer size as max size.
It's a bug that may cause out-of-bound memory access.
For example:
  StrnCpyS (Dest[10], 10, "hello", 6)
  -> StrnLenS ("hello", 10) //< cause out-of bound memory access

In a pool guard enabled environment, when using shell to edit an
existing file which contains empty line, the page fault is met.

The patch fixes the four library functions to avoid such
out-of-bound memory access.

Ruiyu Ni 8a641d2b73 MdeModulePkg/SmmCore: Fix hang due to already-freed memory deference
SmiHandlerUnRegister() validates the DispatchHandle by checking
whether the first 32bit matches to a certain signature
(SMI_HANDLER_SIGNATURE).
But if a caller calls *UnRegister() twice and the memory freed by
first call still contains the signature, the second call may hang.

The patch fixes this issue by locating the DispatchHandle
in all SMI handlers, instead of checking the signature.

Jian J Wang a6a0a59756 MdeModulePkg/Core: fix feature conflict between NX and heap guard
Considering following scenario (both NX memory protection and heap guard
are enabled):

   1. Allocate 3 pages. The attributes of adjacent memory pages will be

      |NOT-PRESENT|  present  |  present  |  present  |NOT-PRESENT|

   2. Free the middle page. The attributes of adjacent memory pages should be

      |NOT-PRESENT|  present  |NOT-PRESENT|  present  |NOT-PRESENT|

      But the NX feature will overwrite the attributes of middle page. So it
      looks still like below, which is wrong.

      |NOT-PRESENT|  present  |  PRESENT  |  present  |NOT-PRESENT|

The solution is checking the first and/or last page of a memory block to be
marked as NX, and skipping them if they are Guard pages.

right after calling AdjustMemoryF().

Laszlo Ersek e75ee97224 UefiCpuPkg/PiSmmCpuDxeSmm: remove unneeded DBs from IA32 SmmStartup()
The SmmStartup() executes in SMM, which is very similar to real mode. Add
"BITS 16" before it and "BITS 32" after it (just before the @32bit label).

Remove the manual 0x66 operand-size override prefixes, for selecting
32-bit operands -- the sizes of our operands trigger NASM to insert the
prefixes automatically in almost every spot. The one place where we have
to add it back manually is the LGDT instruction. (The 0x67 address-size
override prefix is also auto-generated.)

This patch causes NASM to generate byte-identical object code (determined
by disassembling both the pre-patch and post-patch versions, and comparing
the listings), except:

>  0000015E  66B9800000C0      mov ecx,0xc0000080

The only difference is the prefix list order, it changes from:

- 0x67, 0x66, 0x2E

to

- 0x2E, 0x66, 0x67

(0x2E is "CS segment override").

Laszlo Ersek 994df20926 UefiCpuPkg/PiSmmCpuDxeSmm: update comments in IA32 SmmStartup()
The gSmmCr3, gSmmCr4, gSmmCr0 and gSmmJmpAddr global variables are used
for patching assembly instructions, thus we can't yet remove the DB
encodings for those instructions. At least we should add the intended
meanings in comments.

This patch only changes comments.

Star Zeng e434be3c9c MdeModulePkg PiSmmCore: Set ForwardLink to NULL in RemoveOldEntry()
"Entry->Link.ForwardLink = NULL;" is present in RemoveMemoryMapEntry()
for DxeCore, that is correct.
"Entry->Link.ForwardLink = NULL;" is absent in RemoveOldEntry()
for PiSmmCore, that is incorrect.

Without this fix, when FromStack in Entry is TRUE,
the "InsertTailList (&mMapStack[mMapDepth].Link, &Entry->Link);" in
following calling to CoreFreeMemoryMapStack() will fail as the entry
at mMapStack[mMapDepth] actually has been removed from the list.

the capabilities register after reading it from the device registers,
and to call the pre/post host init and reset hooks at the appropriate

Ard Biesheuvel c7be0dd5b9 MdeModulePkg: introduce SD/MMC override protocol
Many ARM based SoCs have integrated SDHCI controllers, and often,
these implementations deviate in subtle ways from the pertinent
specifications. On the one hand, these deviations are quite easy
to work around, but on the other hand, having a collection of SoC
specific workarounds in the generic driver stack is undesirable.

So let's introduce an optional SD/MMC override protocol that we
can invoke at the appropriate moments in the device initialization.
That way, the workaround itself remains platform specific, but we
can still use the generic driver stack on such platforms.
