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".
