Speculative execution is used by processor to avoid having to wait for
data to arrive from memory, or for previous operations to finish, the
processor may speculate as to what will be executed.
If the speculation is incorrect, the speculatively executed instructions
might leave hints such as which memory locations have been brought into
cache. Malicious actors can use the bounds check bypass method (code
gadgets with controlled external inputs) to infer data values that have
been used in speculative operations to reveal secrets which should not
otherwise be accessed.
This commit will focus on the SMI handler(s) registered within the
SmmLockBox driver and insert AsmLfence API to mitigate the
bounds check bypass issue.
For SMI handler SmmLockBoxHandler():
Under "case EFI_SMM_LOCK_BOX_COMMAND_SAVE:", the 'CommBuffer' (controlled
external inputs) is passed to function SmmLockBoxSave().
'TempLockBoxParameterSave.Length' can be a potential cross boundary access
of the 'CommBuffer' during speculative execution. This cross boundary
access is later passed as parameter 'Length' into function SaveLockBox().
Within function SaveLockBox(), the value of 'Length' can be inferred by
code:
"CopyMem ((VOID *)(UINTN)SmramBuffer, (VOID *)(UINTN)Buffer, Length);".
One can observe which part of the content within 'Buffer' was brought into
cache to possibly reveal the value of 'Length'.
Hence, this commit adds a AsmLfence() after the boundary/range checks of
'CommBuffer' to prevent the speculative execution.
And there is a similar case under "case EFI_SMM_LOCK_BOX_COMMAND_UPDATE:"
function SmmLockBoxUpdate() as well. This commits also handles it.

Today's implementation does an exact device path match to check
whether the device path of a console is in ConIn/ConOut/ErrOut.
But that doesn't work for the USB keyboard.
Because when a platform have multiple USB port, ConIn needs to
carry all device paths corresponding to each port.
Even worse, today's BDS core logic removes the device path from
ConIn/ConOut/ErrOut when the connection to that device path fails.
So if user switches the USB keyboard from one port to another across
boot, the USB keyboard doesn't work in the second boot.
ConPlatform driver solved this problem by adding the
IsHotPlugDevice() function. So that for USB keyboard, ConPlatform
doesn't care whether its device path is in ConIn or not.
But the rule is too loose, and now causes platform BDS cannot control
whether to enable USB keyboard as an active console.
The patch changes ConPlatform to support USB short-form device path
when checking whether the device path of a console is in
ConIn/ConOut/ErrOut.
The logic to always accept USB/PCCARD device as active console is
removed.

Commit 09943f5ecc ("MdeModulePkg: Skip to manage usb debug port in EDKII
EHCI driver if it's used by usb debug port driver", 2012-04-28) made the
host controller reset in EhcDriverBindingStart() conditional. The intent
was to avoid the reset when
- one of the USB ports on the host controller was a Debug Port, AND
- the Debug Port was in use.
This translates to the following positive condition: reset the controller
only if:
- no USB port on the host controller is a Debug Port, OR
- the Debug Port is not in use.
Commit 09943f5ecc failed to implement the first subcondition, and thus
the result is too strict now (for resetting the host controller). Relax it
to the correct condition.
This issue was found by Steven Shi on QEMU. QEMU's EHCI device model does
not have a Debug Port. In repeated disconnect / connect cycles, the
controller is never reset in EhcDriverBindingStart(), therefore the
devices on the controller are never re-enumerated after a disconnect.

The change is part of requirement tracked by #BZ1095
https://bugzilla.tianocore.org/show_bug.cgi?id=1095
Background:
Heap Guard and NULL Pointer Detection are very useful features to detect
code flaw in EDK II. If an issue is detected, #PF exception will be
triggered and the BIOS will enter into dead loop, which is the default
behavior of exception handling. From QA perspective, this default behavior
will block them to collect all tests result in reasonable time.
The solution is to introduce non-stop mode to Heap Guard and NULL Pointer
Detection features. This needs to update CpuDxe, PiSmmCpuDxeSmm and
CpuExceptionHandlerLib to allow the code to continue execution after #PF.
The mechanism behind it is the same as SMM Profile feature, in which a
special #PF handler is registered to set the page causing #PF to be
'present' and setup single steop trap, then return the control back to
the instruction accessing that page. Once the instruction is re-executed,
a #DB is triggered and a special handler for it will be called to reset
the page back to 'not-present'.
The non-stop mode is controlled by BIT6 of following PCDs
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask
gEfiMdeModulePkgTokenSpaceGuid.PcdNullPointerDetectionPropertyMask
BIT6 of PcdHeapGuardPropertyMask is used to enable/disable non-stop mode
of Heap Guard feature. It applies to both UEFI and SMM heap guard, if
any of them is enabled.
BIT6 of PcdNullPointerDetectionPropertyMask is used to enable/disable
non-stop mode of NULL Pointer Detection feature. It applies to both
UEFI and SMM NULL Pointer Detection, if any of them is enabled.
The default setting is 'disable', meaning the boot will stop at #PF
exception.

Call BS.AllocatePages in DXE driver and call SMM FreePages with the address of the buffer allocated in the DXE driver. SMM FreePages success and add a non-SMRAM range into SMM heap list. This is not an expected behavior. SMM FreePages should return error for this case and not free the pages.

Today's restriction of VGA device is to have only one VGA device
enabled per PCI segment. It's not correct because several segments
may share one IO / MMIO address space.
We should restrict to have one VGA per Host Bridge because each
Host Bridge has its only IO / MMIO address space.

- local variable name "EfiSimpleFileSystemProtocol" starting with "Efi"

- bogus "FileHandle = NULL" assignments,
- passing a potentially unaligned "FILEPATH_DEVICE_PATH.PathName" field to

"MdeModulePkg/BdsDxe: fall back to a Boot Manager Menu loop before

We want to provide precise info in MemAttribTable
to both OS and SMM, and SMM only gets the info at EndOfDxe.
So we do not update RtCode entry in EndOfDxe.
The impact is that if 3rd part OPROM is runtime, it cannot be executed
at UEFI runtime phase.
Currently, we do not see compatibility issue, because the only runtime
OPROM we found before in UNDI, and UEFI OS will not use UNDI interface
in OS.

Currently:
mPerformanceLength: The length of existing FPDT records.
mMaxPerformanceLength: The maximum length allocated for
mSmmBootPerformanceTable(including FPDT table header length
and existing FPDT records length)
But when compare mPerformanceLength with mMaxPerformanceLength
to check whether need to allocate new buffer for new FPDT
record, we miss to add mPerformanceLength with header length,
which will cause pool allocation behavior is not correct.
Now update the mPerformanceLength to fix this issue:

implemented are 0, 1, 2, 3, 4 and 5.
But we have some platform that has CAP(NP) = 1 (means 2 ports) and
ports implemented are 1 and 2, and has no port 0 implemented, then
current code does not work.

HUB descriptor has variable length.
But the code uses stack (HubDescriptor in PeiDoHubConfig) with fixed
length sizeof(EFI_USB_HUB_DESCRIPTOR) to hold HUB descriptor data.
It uses hard code length value (12) for SuperSpeed path.
And it uses HubDesc->Length for none SuperSpeed path, then there will
be stack overflow when HubDesc->Length is greater than
sizeof(EFI_USB_HUB_DESCRIPTOR).
The patch updates the code to use a big enough buffer to hold the

It uses hard code length value (32 that is greater than
