Kinney, Michael D 7f0301e39a MdeModulePkg/DxeCapsuleLibFmp: Verify nested capsule with FMP
https://bugzilla.tianocore.org/show_bug.cgi?id=873

Update IsNestedFmpCapsule() to verify the CapsuleGuid in
the CapsuleHeader against the installed Firmware Management
Protocol instances.  The current logic that uses the ESRT
Table does not work because capsules are processed before
the ESRT Table is published at the Ready To Boot event.

Michael D Kinney 53be772103 MdeModulePkg/BootGraphicsResourceTableDxe: Use BmpSupportLib
https://bugzilla.tianocore.org/show_bug.cgi?id=800

Use BmpSupportLib to convert a GOP BLT Buffer to the BMP graphics
image that is published in an ACPI BGRT table.

* Remove use of IndustryStandard/Bmp.h include file
* Remove mBmpImageHeaderTemplate.  This is handled by BmpSupportLib
* Clean up code style with function prototypes at top
  and all module global variables together
* Update SetBootLogo() to use SafeIntLib to check input parameters
  for overflows.
* Remove internal function BgrtAcpiTableChecksum().  Use
  CalculateCheckSum8() directly from BgrtReadyToBootEventNotify()
* Remove InstallBootGraphicsResourceTable().  Move all the code into
  BgrtReadyToBootEventNotify() that is signaled at ready to boot.
* Remove all logic that converts a GOP BLT buffer to a BMP graphics image
  and use BmpSupportLib function TranslateGopBltToBmp() instead.
* Use AllocatePool() instead of AllocatePages() to allocate copy of
  BMP image that is provided by BGRT.  This is required to be compatible
  with BmpSupportLib function TranslateGopBltToBmp() that uses
  AllocatePool().
* Zero OemId in BGRT header before filling in value from PCD.
* Get size of PcdAcpiDefaultOemId and only copy the the size of the PCD
  if it is smaller than the size of the OemId field in the BGRT header.
* Use WriteUnaligned24() instead of CopyMem() for the OemTableId field
  of the BGRT header.

But the size of the storage calculated by VfrCompiler is fixed
(calculate with alignment).To avoid the issue cased by above case,
we need to make the total width of the bit fields in the structure
aligned with the size of the defined type for these bit fields.

Michael D Kinney 99a6529e1e MdeModulePkg/ResetSystemRuntimeDxe: Add platform filter and handler
Add support for platform specific reset filters and platform
specific reset handlers to ResetSystem().  A filter may modify
the reset type and reset data and call ResetSystem() with the
modified parameters.  A handler performs the reset action.

The support for platform specific filters and platform specific
handlers is based on the Reset Notification feature added to the
UEFI 2.7 Specification.

Platform specific reset filters are processed first so the final
reset type and reset data can be determined.  In the DXE Phase
The UEFI Reset Notifications are processed second so all UEFI
Drivers that have registered for a Reset Notification can perform
any required clean up actions.  The platform specific reset
handlers are processed third.  If there are no registered
platform specific reset handlers or none of them reset the
platform, then the default reset action based on the
ResetSystemLib is performed.

In the PEI Phase, filters and handlers are registered through
the following 2 PPIs that are based on
EFI_RESET_NOTIFICATION_PROTOCOL.
* gEdkiiPlatformSpecificResetFilterPpiGuid
* gEdkiiPlatformSpecificResetHandlerPpiGuid

In the DXE Phase, filters and handlers are registered through
the following 2 Protocols that are based on
EFI_RESET_NOTIFICATION_PROTOCOL.
* gEdkiiPlatformSpecificResetFilterProtocolGuid
* gEdkiiPlatformSpecificResetHandlerProtocolGuid

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.

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()

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.

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.

Jiaxin Wu 6945837e4c MdeModulePkg/UefiBootManagerLib: Skip the DNS device path node check.
After HTTP boot successfully in home mode, the HTTP device path will be
updated accordingly. So, the new device path may be appended with a DNS
device path node. When executing home mode boot again, the original HTTP
device path will mismatch with the new updated one, which will cause the
HTTP boot failure. So, we need update the current match algorithm to match
the correct FilePath. Since the DNS device path is an optional, we can skip
it check.

This patch is to fix above issue.

Ruiyu Ni a662afb5b0 MdeModulePkg/UsbStorage: Fix "map -r" cannot detect media change
When system boots to Shell without CDROM in the USB CDROM drive,
and then user inserts one CDROM with Eltorito file system,
"map -r" cannot show the the new Eltorito file system.

The root cause is when "map" command probes the media change
by calling dummy ReadBlockIo(), UsbMassStorage ReadBlockIo()
contains a bug that ignores the media change status:
UsbBootDetectMedia() ignores the EFI_MEDIA_CHANGED status
returned from UsbBootIsUnitReady(), in consequence, the
BlockIo protocol re-installation logic doesn't run.

By checking the code change history, below commit
SHA-1: 19bc852765
* remove unnecessary retry logic from usb mass storage driver.
adds the code to skip EFI_MEDIA_CHANGED status.

Talking with the original committer Tian Feng, he said the
change was just a code cleanup, not for a special bug fix.
So I revert part of the patch, only keep the change that
removes unnecessary retry logic. It can fix this bug.

Jian J Wang 425d25699b MdeModulePkg/Core: fix a logic hole in page free
This hole will cause page fault randomly. The root cause is that Guard
page, which is just freed back to page pool but not yet cleared not-
present attribute, will be allocated right away by internal function
CoreFreeMemoryMapStack(). The solution to this issue is to clear the
not-present attribute for freed Guard page before doing any free
operation, instead of after those operation.

The reason we didn't do this before is due to the fact that manipulating
page attributes might cause memory allocation action which would cause a
dead lock inside a memory allocation/free operation. So we always set or
unset Guard page outside the memory lock. After a thorough analysis, we
believe clearing a Guard page will not cause memory allocation because
memory we're to manipulate was already manipulated before for sure.
Therefore there should be no memory allocation occurring in this
situation.

Since we cleared Guard page not-present attribute before freeing instead
of after freeing, the debug code to clear freed memory can now be restored
to its original way (aka no checking and bypassing Guard page).

If PcdDxeNxMemoryProtectionPolicy is set to enable protection for memory

The root cause is that this driver will allocate memory of

EfiReservedMemoryType of memory is marked non-executable, re-start this
driver after relocation will cause exception. The fix is removing the NX
attribute after memory allocation.
