We see UEFI spec is saying to use EfiBootServicesData for ESRT table.
UEFI 2.7 chapter 23.3:
The ESRT shall be stored in memory of type EfiBootServicesData.
And we see EsrtDxe is using AllocatePool for ESRT table, but
EsrtFmpDxe is using AllocateRuntimeZeroPool for ESRT table.
This patch updates code to use EfiBootServicesData for ESRT table
in EsrtFmpDxe.

The variable driver doesn't distinguish "non-volatile non-authenticated"
variables from "volatile non-authenticated" variables, when checking
individual variable sizes against the permitted maximum.
PcdMaxVariableSize covers both kinds.
This prevents volatile non-authenticated variables from carrying large
data between UEFI drivers, despite having no flash impact. One example is
EFI_TLS_CA_CERTIFICATE_VARIABLE, which platforms might want to create as
volatile on every boot: the certificate list can be several hundred KB in
size.
Introduce PcdMaxVolatileVariableSize to represent the limit on individual
volatile non-authenticated variables. The default value is zero, which
makes Variable/RuntimeDxe fall back to PcdMaxVariableSize (i.e. the
current behavior). This is similar to the PcdMaxAuthVariableSize fallback.
Whenever the size limit is enforced, consult MaxVolatileVariableSize as
the last option, after checking
- MaxAuthVariableSize for VARIABLE_ATTRIBUTE_AT_AW,
- and MaxVariableSize for EFI_VARIABLE_NON_VOLATILE.
EFI_VARIABLE_HARDWARE_ERROR_RECORD is always handled separately; it always
takes priority over the three cases listed above.
Introduce the GetMaxVariableSize() helper to consider
PcdMaxVolatileVariableSize, in addition to
GetNonVolatileMaxVariableSize(). GetNonVolatileMaxVariableSize() is
currently called at three sites, and two of those need to start using
GetMaxVariableSize() instead:
- VariableServiceInitialize() [VariableSmm.c]: the SMM comms buffer must
accommodate all kinds of variables,
- VariableCommonInitialize() [Variable.c]: the preallocated scratch space
must also accommodate all kinds of variables,
- InitNonVolatileVariableStore() [Variable.c] can continue using
GetNonVolatileMaxVariableSize().
Don't modify the ReclaimForOS() function as it is specific to non-volatile
variables and should ignore PcdMaxVolatileVariableSize.

BaseTools will generate the optimized PCD database to save the image size
at build time for multiple SKUs. The optimized PCD database layout will be like
below, the PCD database will be composed of the full default SKU data
(PCD_DATABASE_INIT) and the non-default SKU delta data(PCD_DATABASE_SKU_DELTA).
PCD driver will build HOB to store the full default SKU data, and patch HOB
data based on non-default SKU delta data for the SKU set by SetSku(),
it can save memory resource at boot time.
//
// PCD database layout:
// +---------------------------------+
// | PCD_DATABASE_INIT (DEFAULT SKU) |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU A) |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU B) |
// +---------------------------------+
// | ...... |
// +---------------------------------+
//
BaseTools, PCD database and driver updates are needed for this proposal.
For single SKU (default) case, this proposal is expected to have no impact.
For multi-SKU case, PCD database format will be changed.
So, PcdDataBase Version is also updated from 6 to 7.

However, SetAttributes may return EFI_INVALID_PARAMETER when a driver

For instance, this is the case when using the Xen console driver.

SerialSetAttributes is meant to match the behavior of the function

means the function can only return:

- EFI_INVALID_PARAMETER
- EFI_DEVICE_ERROR
However the function SerialPortSetAttributes may also validly return
EFI_UNSUPPORTED. For instance this is the case of the Xen Console

EFI_UNSUPPORTED could be also interpreted as "One or more of the attributes
has an unsupported value". So return EFI_INVALID_PARAMETER in that case.
Lastly, to prevent another return slipping in the future, all the errors

In function FindFileEntry():
Instead of using the function parameter 'FileEntry', use a local
variable to store the buffer allocated for disk read operation.
For the below calling stack:
UdfOpenVolume() -> FindRootDirectory() -> FindFileEntry()
In FindFileEntry(), the call to 'DiskIo->ReadDisk()' is possible (e.g.
media change for a CD/DVD ROM device) to trigger a re-install of the
BlockIO(2) protocol which will further lead to a call of the BindingStop()
& BingdingStart() of the UdfDxe driver.
Meanwhile, for the above listed calling stack, the '**FileEntry'
parameter passed into FindFileEntry() is '&PrivFsData->Root'. 'PrivFsData'
is a driver-managed private data, it will be freed in BindingStop() and
re-allocate in BingdingStart().
In such case, if '*FileEntry' is used to store the allocated buffer, the
information will be lost if 'DiskIo->ReadDisk()' triggers a re-install of
the BlockIO(2) protocol. The subsequent call of the FreePool API:
FreePool (*FileEntry);
will cause issues.
This commit uses a local variable to store the allocated buffer.

Historically many drives or medias do not correctly return their value
for block N - which is also referred as last addressable/recorded block.
When they do so, there is still a problem when relying on last recorded
block number returned by SCSI commands READ CAPACITY and READ TRACK
INFORMATION - that is, between block 0 and block N there may be
unwritten blocks which are located outside any track.
That said, the Partition driver was unable to find AVDP at block N on
certain medias that do not either return or report their last recorded
block number correctly.
Apparently there is no official or correct way to find the correct block
number, however tools like the Philips UDF Conformance Tool (udf_test)
apply a correction by searching for an AVDP or VAT in blocks N through
N-456 -- this can be observed by looking at the log reported by udf_test
on those CD/DVD medias. So, if the AVDP or VAT is found, then it sets
the last recorded block number to where AVDP or VAT was located.
With the below setence in UDF 2.60, 6.13.2.2 Background Physical
Formatting:
"... the second AVDP must be recorded after the Background physical
Formatting has been finished..."
Implies that the last recorded block is the one where second AVDP was
recorded.
This patch implements a similar way to correct the last recorded block
number by searching for last AVDP in blocks N-1 through N-512 on those
certain medias, as well as ensure a minimum number of 2 AVDPs found as
specified by ECMA 167 and UDF 2.60 specifications.

reported "Xen Console input very slow in recent UEFI" that appears
after 4cf3f37c87 "MdeModulePkg
SerialDxe: Process timeout consistently in SerialRead".
Julien did more debugging and find out the following is happening in
TerminalConInTimerHandler (MdeModulePkg/Universal/Console/TerminalDxe)
when a character is received:
1) GetControl will return EFI_SERIAL_INPUT_BUFFER_EMPTY unset
=> Entering in the loop to fetch character from the serial
2) GetOneKeyFromSerial()
=> Return directly with the character read
3) Looping as the fifo is not full and no error
4) GetOneKeyFromSerial() -> SerialRead()
=> No more character so SerialPortPoll() will return FALSE and loop
until timeout
=> Return EFI_TIMEOUT
5) Exiting the loop from TerminalConInTimerHandler
6) Characters are printed
After some investigation, I found it is related to the Timeout value.
The Timeout is 1000000 (1s) by default to follow UEFI spec.
And the Terminal driver will recalculate and set the Timeout value
based on the properties of UART in TerminalDriverBindingStart()/
TerminalConInTimerHandler().
SerialInTimeOut = 0;
if (Mode->BaudRate != 0) {
//
// According to BAUD rate to calculate the timeout value.
//
SerialInTimeOut = (1 + Mode->DataBits + Mode->StopBits) *
2 * 1000000 / (UINTN) Mode->BaudRate;
}
For example, based on the PCD values of PcdUartDefaultBaudRate,
PcdUartDefaultDataBits and PcdUartDefaultStopBits, SerialInTimeOut =
(1 + 8 + 1) * 2 * 1000000 / (UINTN) 115200 = 173 (us).
When SerialDxe is used,
TerminalDriverBindingStart()/TerminalConInTimerHandler() ->
SerialIo->SetAttributes() ->
SerialSetAttributes() ->
SerialPortSetAttributes()
Some implementations of SerialPortSetAttributes() could handle the
input parameters and return RETURN_SUCCESS, for example
BaseSerialPortLib16550, then Timeout value will be changed to 173 (us),
no "slow down" will be observed.
But some implementations of SerialPortSetAttributes() just return
RETURN_UNSUPPORTED, for example XenConsoleSerialPortLib, then Timeout
value will be not changed and kept 1000000 (1s), "slow down" will be
observed.
SerialPortLib instance can be enhanced to
1. Handle the input parameters and return status accordingly instead of
just returning RETURN_UNSUPPORTED in SerialPortSetAttributes().
2. Just return RETURN_SUCCESS instead of RETURN_UNSUPPORTED in
SerialPortSetAttributes() if the instance does not care the input
parameters at all.
And SerialDxe can also be enhanced like this patch to be more robust
to handle Timeout change.

However, some OS kernels create the MOR variable even if the platform
firmware does not support it (see one Bugzilla reference below). This OS
issue breaks the logic added in the last patch.
Strengthen the MOR check by searching for the TCG or TCG2 protocols, as
edk2's implementation of MOR depends on (one of) those protocols.
The protocols are defined under MdePkg, thus there's no inter-package
dependency issue. In addition, calling UEFI services in
MorLockInitAtEndOfDxe() is safe, due to the following order of events /
actions:
- platform BDS signals the EndOfDxe event group,
- the SMM core installs the SmmEndOfDxe protocol,
- MorLockInitAtEndOfDxe() is invoked, and it calls UEFI services,
- some time later, platform BDS installs the DxeSmmReadyToLock protocol,
- SMM / SMRAM is locked down and UEFI services become unavailable to SMM
drivers.

prerequisite spec (because it does not include the
"SecurityPkg/Tcg/MemoryOverwriteControl/TcgMor.inf" driver), but appears
to support MORL from the dependent Microsoft spec.
"winload.efi" notices this inconsistency, and disables the Device Guard
Virtualization Based Security in Windows Server 2016 and Windows 10 64-bit
Enterprise.
If the platform includes
"SecurityPkg/Tcg/MemoryOverwriteControl/TcgMor.inf", then MOR will exist
by the time EndOfDxe is reached, and VariableSmm can safely create MORL.
Otherwise, do not create MORL (delete it if it exists), and also prevent
other modules from creating it.

The SetMorLockVariable() function sets "mMorLockPassThru" to TRUE
temporarily, so that it can set the MOR Control Lock variable to
well-formed values without permission checks.
In the next patch, we'll need the same override for deleting the MOR
Control Lock variable; hence obey "mMorLockPassThru" in the deletion
branch of SetVariableCheckHandlerMorLock() as well.

Introduce the MorLockInitAtEndOfDxe() hook, in order to allow
MorLockInit() to delay / queue operations until EndOfDxe. (Or, if the
platform never signals EndOfDxe, until ReadyToBoot.)
Call MorLockInitAtEndOfDxe() whenever we set "mEndOfDxe" to TRUE:
- in VariableRuntimeDxe:
- in the OnReadyToBoot() function,
- in the OnEndOfDxe() function;
- in VariableSmm:
- on the SMM_VARIABLE_FUNCTION_READY_TO_BOOT SMI request,
- in the SmmEndOfDxeCallback() function.
For now, implement MorLockInitAtEndOfDxe() as a no-op in both
VariableRuntimeDxe and VariableSmm.

The MorLockInit() and SetVariableCheckHandlerMor() functions have separate
implementations for VariableRuntimeDxe (= unprivileged, unified
DXE_RUNTIME driver) and VariableSmm (= privileged, DXE_SMM back-end of the
split variable driver).
Move their declarations from "Variable.c" to "PrivilegePolymorphic.h", so
that the compiler enforce that the declarations and the definitions match.
(All C source files with the call sites and the function definitions
already include "PrivilegePolymorphic.h" via "Variable.h".)
At the same time:
- replace two typos in the MorLockInit() description:
- replace "EFI_SUCEESS" with "EFI_SUCCESS",
- replace "MOR Lock Control" with "MOR Control Lock";
- in the SetVariableCheckHandlerMor() description:
- replace @param with @param[in],
- correct the description of the Attributes parameter (suggested by Star
Zeng <star.zeng@intel.com>),
- rewrap the comment to 80 columns.

If the platform supports SMM, a gRT->SetVariable() call at boot time
results in the following call tree to SecureBootHook():
RuntimeServiceSetVariable() [VariableSmmRuntimeDxe.c, unprivileged]
SmmVariableHandler() [VariableSmm.c, PRIVILEGED]
VariableServiceSetVariable() [Variable.c, PRIVILEGED]
SecureBootHook() [VariableSmm.c, PRIVILEGED]
//
// do nothing
//
SecureBootHook() [Measurement.c, unprivileged]
//
// measure variable if it
// is related to SB policy
//
And if the platform does not support SMM:
VariableServiceSetVariable() [Variable.c, unprivileged]
SecureBootHook() [Measurement.c, unprivileged]
//
// measure variable if it
// is related to SB policy
//
In other words, the measurement always happens outside of SMM.
Because there are two implementations of the SecureBootHook() API, one
that is called from SMM and does nothing, and another that is called
outside of SMM and measures variables, the function declaration should be
in a header file. This way the compiler can enforce that the function
declaration and all function definitions match.
"Variable.h" is used for "including common header files, defining internal
structures and functions used by Variable modules". Technically, we could
declare SecureBootHook() in "Variable.h". However, "Measurement.c" and
"VariableSmmRuntimeDxe.c" themselves do not include "Variable.h", and that
is likely intentional -- "Variable.h" exposes so much of the privileged
variable implementation that it is likely excluded from these C source
files on purpose.
Therefore introduce a new header file called "PrivilegePolymorphic.h".
"Variable.h" includes this header (so that all C source files that have
been allowed to see the variable internals learn about the new
SecureBootHook() declaration immediately). In "Measurement.c" and
"VariableSmmRuntimeDxe.c", include *only* the new header.
This change cleans up commit fa0737a839 ("MdeModulePkg Variable: Merge
from Auth Variable driver in SecurityPkg", 2015-07-01).

ever set internally to UdfDxe. Therefore any other flag value would be a
bug in UdfDxe.
ASSERT() specifically that "ReadFileInfo->Flags" has been set correctly,
so that the reader is not left wondering what happens if none of the enum
constants match.

Codes:

Offset = ReadFileInfo->FilePosition - FilePosition;
if (Offset < 0) {

}
Offset is UINT64 can not < 0, so the code logic may have some issue.
and Offset = -(Offset) may build failure in some circumstance.
Previously type cast Offset to INT64 to fix build break. Now remove
the type cast. Then can to check the code logic later.

This patch introduces UDF file system support in EDK2. All block devices
that support BlockIo and DiskIo protocols and contain a valid UDF file
system - as specified by OSTA Universal Disk Format (revisions 1.02
through 2.60) - will be installed EFI_SIMPLE_FILE_SYSTEM_PROTOCOL to
provide access to underlying file system.
File system operations on regular, directory and symlink files are
supported.

The IP driver uses EfiCreateProtocolNotifyEvent() to register notify callback
function for IpSec protocol, but it didn't notice that the callback will always
be executed at least once, even the protocol wasn't in handle database.
As a result, the Ip4IpSecProcessPacket() will still always call LocateProtocol()
even the IpSec protocol is not installed, which will impact the network
performance.

reported the timeout processing in SerialRead is not consistent.
Since SerialPortPoll only checks the status of serial port and
returns immediately, and SerialPortRead does not really implement
a time out mechanism and will always wait for enough input,
it will cause below results:
1. If there is no serial input at all, this interface will return
timeout immediately without any waiting;
2. If there is A characters in serial port FIFO, and caller requires
A+1 characters, it will wait until a new input is coming and timeout
will not really occur.
This patch is to update SerialRead() to check SerialPortPoll() and
read data through SerialPortRead() one byte by one byte, and check
timeout against mSerialIoMode.Timeout if no input.
