This patch is used to fix connection failure issue after correct the SPD
and re-enable IPsec. The driver should not update the SadEntry's SpdSelector
when doing SpdEntry modification. SadEntry's SpdSelector may not equal to
this edited SpdEntry’s Selector.

Since PcdPropertiesTableEnable is used by the DXE Core (in the
InstallPropertiesTable() function, which runs at End-of-Dxe), we must also
change the PcdLib class resolution for that module, from the default
BasePcdLibNull to DxePcdLib.
Traditionally we've considered the DXE Core to be incapable of accessing
dynamic PCDs -- the PCD PPI is not available any longer to the DXE Core,
and the PCD Protocol is not available to it *yet*. There are exceptions
however: if the DXE Core can ensure, by whatever means, that the PCD
Protocol *is* available, then DxePcdLib will just work (the latter even
lists DXE_CORE as an allowed client module type). Namely, DxePcdLib looks
up the PCD Protocol dynamically, on the first library call that actually
needs it (for accessing a dynamic PCD); the lookup doesn't occur in a
library constructor.
And because the DXE Core fetches PcdPropertiesTableEnable at End-of-Dxe,
the PCD Protocol is definitely available then.
In addition, we change the default value of PcdPropertiesTableEnable from
the inherited TRUE to FALSE. It makes no difference at this point (our
runtime DXE drivers are not built with the required 4KB section alignment
anyway), but it's better to be clear about this. The properties table
feature requires OS compatibility, and it breaks Windows 7 minimally.
Therefore the default should be FALSE.

Plus, because PcdSetNxForStack is used by the DXE IPL PEIM (in the

What to do:
1. Remove a hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback".
1.1. Use SmmExitBootServices and SmmLegacyBoot notification to record
AtRuntime flag.
1.2. Use mBootScriptDataBootTimeGuid LockBox to save boot time boot
script data to handle potential INSERT boot script at runtime in SMM.
2. Do not depend on OS to help restore ACPINvs data and use
EfiReservedMemoryType instead of EfiACPIMemoryNVS.
2.1. Use mBootScriptSmmPrivateDataGuid LockBox to save boot script
SMM private data with BackFromS3 = TRUE at runtime. S3 resume
will help restore it to tell the Library the system is back
from S3.
Why to do:
1. The hidden assumption "No SMM driver writes BootScript between
SmmReadyToLock and S3SleepEntryCallback" will cause confusion to
the library's consumer and block the usage of "SMM driver writes
BootScript after SmmReadyToLock". So Remove the assumption.
2. In original code, there might be a corner case that malicious
code patch ACPINvs boot TableLength field same as SMM boot script.
So that it can skip the table restore. The impact is that BootScript
in SMM may be overridden by malicious code.
--------------------
CopyMem ((VOID*)&TableHeader, (VOID*)mS3BootScriptTablePtr->TableBase, sizeof(EFI_BOOT_SCRIPT_TABLE_HEADER));
if (mS3BootScriptTablePtr->TableLength + sizeof(EFI_BOOT_SCRIPT_TERMINATE) != TableHeader.TableLength) { // TableLength is in NVS
......
//
// NOTE: We should NOT use TableHeader.TableLength, because it is already updated to be whole length.
//
mS3BootScriptTablePtr->TableLength = (UINT32)(mLockBoxLength - sizeof(EFI_BOOT_SCRIPT_TERMINATE)); ? This line can be skipped.
--------------------
So use EfiReservedMemoryType instead of EfiACPIMemoryNVS as the code
has been updated to not depend on OS to help restore ACPINvs data.

The specification of the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru()
function documents the EFI_BAD_BUFFER_SIZE return status, and the
EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN host adapter
status.
These allow an EFI_EXT_SCSI_PASS_THRU_PROTOCOL implementation to request
higher layers in the stack (in this instance, UefiScsiLib and ScsiDiskDxe)
to break up the transfer into smaller pieces.
These conditions percolate up the stack correctly: the retry loops in
ScsiDiskDxe's ScsiDiskReadSectors() and ScsiDiskWriteSectors() functions
correctly and transparently update the transfer size (ByteCount),
accommodating any shortening requested by lower levels of the stack. After
the loop -- if the request ultimately succeeds -- SectorCount is even
recalculated from the final ByteCount, to see how many sectors the outer
loop should advance.
However, the inner (ie. retry) loops both have the same error: when the
underlying protocols request the transfer to be shortened, the decrease in
transfer size (ie. ByteCount) should immediately be reflected in
SectorCount. Otherwise the sector count encoded in the CDB will exceed the
transfer size, which is a permanent error.
This issue has been witnessed while booting
en_windows_8.1_pro_n_vl_with_update_x86_dvd_6051127.iso
on the 32-bit build of OVMF, from a virtio-scsi CD-ROM:
(1) "cdboot.efi" correctly requested (from far atop) a long read:
Timeout=940000000
CdbLength=10
DataDir=Read
InTransferLength=134215680
OutTransferLength=0
SenseDataLength=108
Cdb: 28 00 00 00 25 DD 00 FF FF 00
^ ^^^^^^^^^^^ ^^^^^
| | |
| | number of 2KB sectors to read,
| | corresponding to 2048 * 65535 = 134215680 bytes
| | (see InTransferLength above)
| |
| LBA to read from
|
READ (10)
(2) In turn, the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function
provided by "OvmfPkg/VirtioScsiDxe/VirtioScsi.c" asked for the request
to be shortened:
InTransferLength=16776704
OutTransferLength=16776704
SenseDataLength=0
HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN
TargetStatus=0
Status=EFI_BAD_BUFFER_SIZE
(3) Then ScsiDiskReadSectors() in
"MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDisk.c" retried the request
with correctly shortened transfer length, but incorrectly unchanged
sector count:
Timeout=940000000
CdbLength=10
DataDir=Read
InTransferLength=16776704 <--- updated as requested
OutTransferLength=0
SenseDataLength=108
Cdb: 28 00 00 00 25 DD 00 FF FF 00
^ ^^^^^^^^^^^ ^^^^^
| | |
| | not changed!
| |
| LBA to read from
|
READ (10)
(4) Since 65535 sectors of 2KB each wouldn't fit in a buffer of approx.
16MB, QEMU's virtio-scsi controller unconditionally rejected this
request with VIRTIO_SCSI_S_OVERRUN, which VirtioScsiDxe then mapped
to:
InTransferLength=16776704
OutTransferLength=0
SenseDataLength=0
HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN
TargetStatus=0
Status=EFI_DEVICE_ERROR
(5) After two more tries of the same, ScsiDiskDxe passed up the error,
which ultimately caused "cdboot.efi" to BSOD.
Many thanks to Larry Cleeton from Microsoft for helping debug
"cdboot.efi".

During page entry attribute update, if there are table entries
between starting BlockEntry and LastBlockEntry, table entries will be
set as block entries and the allocated memory of the tables will be
leaked.
So instead, we break the inner loop when we find a table entry and run
outer loop again to step into the table by the same logic.

[ardb: move termination condition check inside the loop]

Below code has bug since *BlockEntrySize and *TableLevel are not
updated accordingly:
if (IndexLevel == PageLevel) {
// And get the appropriate BlockEntry at the next level
BlockEntry = (UINT64*)TT_GET_ENTRY_FOR_ADDRESS (TranslationTable, \
IndexLevel + 1, RegionStart);
// Set the last block for this new table
*LastBlockEntry = TT_LAST_BLOCK_ADDRESS(TranslationTable, \
TT_ENTRY_COUNT);
}
Also it doesn't check recursively to get the last level, e.g. the
initial PageLevel is 1 and we already have level 2 and 3 tables at
this address.
What's more, *LastBlockEntry was not updated when we get a table and
IndexLevel != PageLevel.
So we reorganize the sequence, only updating TranslationTable,
PageLevel and BlockEntry in the loop, and setting the other output
parameters with the final PageLevel before returning.
And LastBlockEntry is only an OUT parameter.

There is a hidden bug for below code:
(1 << BaseAddressAlignment) & *BlockEntrySize
From disassembly code, we can see the literal number 1 will be treated
as INT32 by compiler by default, and we'll get 0xFFFFFFFF80000000 when
BaseAddressAlignment is equal to 31. So we will always get 31 when
alignment is larger than 31.
if ((1 << BaseAddressAlignment) & *BlockEntrySize) {
5224: f9404be0 ldr x0, [sp,#144]
5228: 2a0003e1 mov w1, w0
522c: 52800020 mov w0, #0x1 // #1
5230: 1ac12000 lsl w0, w0, w1
5234: 93407c01 sxtw x1, w0
The bug can be replayed on QEMU AARCH64; by adding some debug print,
we can see lots of level 1 tables created (for block of 1GB) even
when the region is large enough to use 512GB block size.
Use LowBitSet64() in BaseLib instead to fix the bug.

The bug can be triggered when alignment of Base is larger than Length
by 2 level of page granularity, e.g.
Base is 0x4000_0000, Length is 0x1000
The original code will change 2MB page level and we will get a
negative remaining length.

The code has a simple bug on calculating aligned page table address.
We can just use AllocateAlignedPages in MemoryAllocationLib instead.

The mBmPerfHeader.Count isn't reset to 0 in BmWriteBootToOsPerformanceData()
so when the actual performance data entry count exceeds the LimitCount,
the performance data collection breaks on condition
if (mBmPerfHeader.Count == LimitCount), but 2nd time calling this function
will not break on condition if (mBmPerfHeader.Count == LimitCount) because
the mBmPerfHeader.Count always bigger than LimitCount, which results buffer
overrun.
