Star Zeng d2dbe5b70b MdeModulePkg VarCheckLib: R18611 was thoughtless for property set
R18611 only updated the logic to return correct property
when no property set to variable with wildcard name.
But VariablePropertySet needs the pointer of property data for set.
So roll back the change in VariablePropertyGetWithWildcardName at R18611,
and check the property revision first in VariablePropertyGet and
SetVariableCheck before using the property data.

Laszlo Ersek 8a4b243578 MdeModulePkg: FaultTolerantWriteDxe: mellow DEBUGs about workspace reinit
The IsValidWorkSpace() function checks if the working block header of the
workspace is valid. A mismatch detected by this function is not
necessarily an error; it can happen with an as-yet unwritten flash chip,
which is e.g. common and normal when a new ArmVirtQemu virtual machine is
booted. Therefore downgrade the message emitted by IsValidWorkSpace() from
EFI_D_ERROR to EFI_D_INFO, and change the wording from "error" to
"mismatch".

The only caller of IsValidWorkSpace(), InitFtwProtocol(), handles all of
the following cases:

(1) IsValidWorkSpace() succeeds for the working block -- this is normal
    operation,

(2) IsValidWorkSpace() fails for the working block, but succeeds for the
    spare block -- InitFtwProtocol() then restores the working block from
    the spare block,

(3) IsValidWorkSpace() fails for both the working and spare blocks --
    InitFtwProtocol() reinitializes the full workspace.

In cases (2) and (3), InitFtwProtocol() logs additional messages about the
branch taken. Their current level is EFI_D_ERROR, but the messages are
arguably informative, not necessarily error reports.

Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they
don't clutter the debug output when the PcdDebugPrintErrorLevel mask only
enables EFI_D_ERROR (i.e., in a "silent" build).

These messages have annoyed / confused users; see for example:
- https://bugzilla.redhat.com/show_bug.cgi?id=1270279

Joseph Shifflett 25a2664625 MdeModulePkg: exit pci function loops early if device is not multi-function
When looping through all PCI functions, code should not look for functions
1-7 if function 0 is not present or if function 0 indicates the device is
not multifunction.  Prior to this fix the code would use stale data in a
buffer to determine if a device is multifunction even if function 0 is not
present.  This fixes a code bug and provides very small performance
improvements.

PCI 2.3 Specification states: They [multifunction devices] are also
required to always implement function 0 in the device. Implementing other
functions is optional and may be assigned in any order.

Samer El-Haj-Mahmoud 9feefde0cb MdeModulePkg Ip4Dxe: Ip4Config2 to request DHCP Option6 DNS server IP
Ip4Config2 protocol implementation must request for DNS server info when the
policy is set to DHCP. And when a DHCP server responds to it with a list of
DNS server addresses, it must parse it and set it for the instance. Without
this, nobody can do a Ip4Config->GetData for DNS server IPs before calling
Dns->Configure(). This will mean a DHCP is initiated when calling
Dns->Configure(), thus causing serious performance issues. This patch
attempts to address this issue.

Reza Jelveh 2dc5090d76 MdeModulePkg: AtaAtapiPassThru: select master/slave around DIAG command
Some IDE controllers only update ID fields such as sector information on
specific commands such as the DIAG command.

The master/slave device is therefore selected both before and after
sending the DIAG command; otherwise reading the IDE registers yields the
master's ID fields.

(Reza's patch originally *moved* the master/slave selection from after the
DIAG command before it, however Feng asked for the original master/slave
select to be preserved; effectively making the master/slave select
*bracket* the DIAG command. See this subthread:
<http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10545/focus=10550>.)

There is a penalty associated with searching the protocol database on

Unregister needs to be done only if the Event is for a RegisterProtocolNotify.

So extend the ExFlag in IEVENT to a UINT8 and define new flags that can
be set to indicate if the Event is part of a group, or registered on a
protocol notify. Then in CloseEvent, call UnregisterProtocolNotify only
if the register protocol notify flag is set.

Star Zeng 960f2d533b MdeModulePkg PiDxeS3BootScriptLib: Remove a hidden assumption.
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 driver binding start function in SNP.c goes through all the BARs and get
the last BAR index for use. Theoretically it should work with all valid BARs,
but we got reports some device did always use the first valid BAR, so we change
the logic in SNP to use the first found BAR index instead of the last one.

Laszlo Ersek 5abc2a70da MdeModulePkg: ScsiDiskDxe: adapt SectorCount when shortening transfers
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".

on the IpSec protocol installation, and process only if the protocol is installed.
This speeds up the network stacks when IpSec is not installed since there is a
