Liming Gao f1f8ce6de7 MdeModulePkg: Don't build VarCheckUefiLib and DxeCore for EBC arch
EBC build failure is caused by d7a09cb86a.
It changes MAX_UINTN and MAX_ADDRESS definition as below. VarCheckUefiLib
and DxeCore uses MAX_UINTN and MAX_ADDRESS in the global data initialization.
New style has >> operator, and not supported by EBC compiler.
The fix is not to build VarCheckUefiLib and DxeCore for EBC arch.

#define MAX_UINTN  ((UINTN) ~0)
==>
#define MAX_UINTN  ((UINTN)(~0ULL >> (64 - sizeof (INTN) * 8)))

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.

That fix didn't take the 0 page to free into account, which still

The fix is just moving the calling of UnsetGuardPage() to the place
right after calling AdjustMemoryF().

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.

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).

The Graphics Output Protocol's mode information specifies the
PixelsPerScanLine property. Most of the time this is identical to
HorizontalResolution. However, due to alignment requirements etc. it
may be slightly larger. I.e. each scan line will have some "pixels"
that are not visible on the screen but consume space in the frame
buffer.

If the graphics output protocol correctly initializes
HorizontalResolution to 1366 and PixelsPerScanLine to 1376. As a
result the graphics output is broken.

If setting HorizontalResolution to 1376 instead, the output is fine
(except for 10 invisible pixels on the right of the screen).

The patch fixes this bug by using PixelsPerScanLine when calculating
the line width.

Wang Fan 018432f0ce MdeModulePkg/Ip4Dxe: Add an independent timer for reconfig checking
* Since wireless network can switch at very short time, the time interval
  of reconfig event checking is too long for this case. To achieve better
  performance and scalability, separate this task from Ip4 tick timer.

Wang Fan 479a3b6053 MdeModulePkg/Dhcp4Dxe: Free NET_BUF data after sent out to avoid memory leak
* When build a DHCP message in function DhcpSendMessage() or DhcpRetransmit(),
a new NET_BUF is created by the library of NetbufFromExt, but it's not freed
after it is sent out. This patch is to fix this memory leak issue.

V2:
* Since packet has already been referred by DhcpSb->LastPacket, and will be
freed when sending another packet or clean up, there is no need to add an
extra free function in NetbufFromExt.

Ruiyu Ni ada385843b MdeModulePkg/PciBus: Change switch-case to if-else to fix EBC build
EBC compiler doesn't treat EFI_xxx as constant due to these macros
are UINT64 type in 64bit env and UINT32 type in 32bit env.
So it reports error when "case EFI_xxx" is used.
The patch changes to use if-else to fix EBC build failure.

Jiaxin Wu d32159853d MdeModulePkg/IScsiDxe: Set ExitBootServiceEvent to NULL after close it.
v2:
* Refine the commit log.

There are two place to close the ISCSI ExitBootServiceEvent:
#1.IScsiOnExitBootService(), which is the callback function of
   ExitBootServiceEvent.
#2.IScsiCleanDriverData(), which will be invoked by ISCSI driver
   binding stop().

So, the ExitBootServiceEvent will be closed and freed when exit boot
server is triggered. But it may be closed and freed again in ISCSI driver
binding stop(), which will result in the issue recorded at
https://bugzilla.tianocore.org/show_bug.cgi?id=742.

This patch is to resolve the issue.
