Paulo Alcantara 99c9b94905 MdeModulePkg: Initial UDF/ECMA-167 file system support
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.

Paulo Alcantara 8aafec2c13 MdeModulePkg/PartitionDxe: Add UDF file system support
Scan for UDF file systems on all block devices, as specified by OSTA
Universal Disk Format Specification 2.60, and install a Vendor-Defined
Media Device Path for each file system found.

The Vendor-Defined Media Device Path for the UDF file system is then
checked by UdfDxe to decide whether or not start the driver.

Laszlo Ersek 6fb8ddd36b MdeModulePkg/AtaAtapiPassThru: disable the device at ExitBootServices()
The AtaAtapiPassThru driver maps three system memory regions for Bus
Master Common Buffer operation on the following call path, if the
controller has PCI_CLASS_MASS_STORAGE_SATADPA class code:

  AtaAtapiPassThruStart()
    EnumerateAttachedDevice()
      AhciModeInitialization()
        AhciCreateTransferDescriptor()

The device is disabled (including Bus Master DMA) when the controller is
unbound, in AtaAtapiPassThruStop(). Then the regions are unmapped.

The former step should also be done when we exit the boot services, and
the OS gains ownership of system memory.

Laszlo Ersek 509daa658b MdeModulePkg/AtaAtapiPassThru: unmap DMA buffers after disabling BM DMA
In AtaAtapiPassThruStop(), if the device has been operating in AHCI mode,
we unmap the DMA buffers and then disable the device (including bus master
DMA). The order of these actions is wrong; we shouldn't unmap DMA buffers
until bus master DMA is turned off. Reverse the steps.

Fu Siyuan 5aae2d35de MdeModulePkg/Ip4Dxe: fix a bug in IP4 driver for IpSec protocol notify.
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.

Hao Wu 3f3a69b87a MdeModulePkg/UefiBootManagerLib: Generate boot description for SD/eMMC
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=620

Adds the support for SD/eMMC device path to show as a boot option.

The CID register content (returned from DiskInfo->Inquiry) seems do not
provide very useful/readable 'OEM/Application ID' and 'Product name'
field.

For SD devices, the OID is a 2-character ASCII string and the Product name
is a 5-character ASCII string.

For eMMC devices, the OID is an 8-bit binary number and the Product name
is a 6-character ASCII string.

These strings are relatively short and do not provide a very readable
description. Hence, this commit uses general 'SD (eMMC) Device' for the
boot option description.

Laszlo Ersek ce13d2d8c8 MdeModulePkg/ScsiBusDxe: don't produce ScsiIo for nonexistent LUNs, part 2
The SPC-4 says about INQUIRY,

> In response to an INQUIRY command received by an incorrect logical unit,
> the SCSI target device shall return the INQUIRY data with the peripheral
> qualifier set to the value defined in 6.4.2. The INQUIRY command shall
> return CHECK CONDITION status only when the device server is unable to
> return the requested INQUIRY data.

When a device server takes the second branch, and returns CHECK CONDITION
for a nonexistent LUN, the InquiryData structure in the
DiscoverScsiDevice() function remains filled with the original zeros.

DiscoverScsiDevice() then sees zero in both Peripheral_Qualifier and
Peripheral_Type, and therefore ScsiBusDxe produces a ScsiIo protocol
instance with device type zero, for the nonexistent LUN.

Device type zero is EFI_SCSI_TYPE_DISK. Thus ScsiDiskDxe binds the bogus
ScsiIo protocol interface, and produces a similarly bogus BlockIo
interface on top. This ripples up to BDS, where UefiBootManagerLib can
auto-generate bogus UEFI boot options for the nonexistent LUNs.

This has been encountered with QEMU, after commit ded6ddc5a7b9 ("scsi:
clarify sense codes for LUN0 emulation", 2017-08-04). QEMU now answers
INQUIRY commands that were directed to nonexistent LUNs with:

> DiscoverScsiDevice:1361: Lun=2 HostAdapterStatus=0 TargetStatus=2
>                          SenseDataLength=18 InquiryDataLength=96
> Sense {
> Sense 000000 70 00 05 00 00 00 00 0A 00 00 00 00 25 00 00 00
> Sense 000010 00 00
> Sense }
> Inquiry {
> Inquiry 000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry }

The interesting fields are:
- HostAdapterStatus=0 (OK),
- TargetStatus=2 (CHECK CONDITION),
- Sense/Error_Code=0x70 (Current error, Fixed description)
- Sense/Sense_Key=0x05 (ILLEGAL REQUEST)

According to SPC-4 "Table 41 -- Sense key descriptions (part 2 of 2)",
ILLEGAL REQUEST is justified when "the command was addressed to an
incorrect logical unit number".

Thus, recognize this kind of answer for nonexistent LUNs.

(

Checking the status fields and the sense data is justified anyway,
according to the documentation of ScsiInquiryCommand():

>   @retval EFI_SUCCESS                    The command was executed
>                                          successfully. See

>                                          TargetStatus, SenseDataLength,
>                                          and SenseData in that order for

Laszlo Ersek 897efb977f MdeModulePkg/ScsiBusDxe: don't produce ScsiIo for nonexistent LUNs, part 1
The SPC-4 spec says about the INQUIRY data, in "Table 138 -- Peripheral
qualifier":

> Qualifier = 011b  The device server is not capable of supporting a
>                   peripheral device on this logical unit. For this
>                   peripheral qualifier the peripheral device type shall
>                   be set to 1Fh. All other peripheral device type values
>                   are reserved for this peripheral qualifier.

Accordingly, the DiscoverScsiDevice() function returns FALSE if
Peripheral_Qualifier is 3 decimal, but Peripheral_Type differs from 1Fh.
This is a valid sanity check -- such combinations are reserved.

When Peripheral_Qualifier is 3, and Peripheral_Type is 1Fh, then
DiscoverScsiDevice() returns TRUE. While this combination is not reserved,
returning TRUE for it is incorrect: Peripheral_Type 1Fh stands for
"Unknown or no device type", and this combination is returned in
particular when the INQUIRY command was directed to a nonexistent LUN.
Quoting the spec:

> In response to an INQUIRY command received by an incorrect logical unit,
> the SCSI target device shall return the INQUIRY data with the peripheral
> qualifier set to the value defined in 6.4.2. [...]
>
> [...]
>
> The PERIPHERAL QUALIFIER field and PERIPHERAL DEVICE TYPE field identify
> the peripheral device connected to the logical unit. If the SCSI target
> device is not capable of supporting a peripheral device connected to
> this logical unit, the device server shall set these fields to 7Fh
> (i.e., PERIPHERAL QUALIFIER field set to 011b and PERIPHERAL DEVICE TYPE
> field set to 1Fh).

The consequence of this bug is that for each nonexistent Target/LUN pair,
we produce a useless ScsiIo protocol interface. The internal
"ScsiIoDevice->ScsiDeviceType" field will be set to 0x1f, and it will be
returned to higher-level SCSI drivers when they call
ScsiIo->GetDeviceType().

Given that 0x1f means "Unknown or no device type", no higher-level driver
can ever support it, so these ScsiIo protocol interfaces are useless.

The fix is to return FALSE for the (Peripheral_Qualifier=3,
Peripheral_Type=0x1f) combination. With that however we reject the whole
Peripheral_Qualifier=3 space (justifiedly -- see the definition above),
which lets us simplify the code.

Hao Wu b92efc9fe5 MdeModulePkg/EmmcDxe: Make sure no extra data is erased by EraseBlocks
V3 changes:
Add debug messages for new return path when successfully erase the
specified blocks. Refine logic for calculating the size for writing
zeros to device.

V2 changes:

The Trim command is not supported on all eMMC devices. For those devices
that do not support such command, add codes to handle the scenario.

Commit message:

The current implementation of the Erase Block Protocol service
EraseBlocks() uses the erase command. According to spec eMMC Electrical
Standard 5.1, Section 6.6.9:

The erasable unit of the eMMC is the "Erase Group"; Erase group is
measured in write blocks that are the basic writable units of the Device.
...
When the Erase is executed it will apply to all write blocks within an
erase group.

However, code logic in function EmmcEraseBlocks() does not check whether
the blocks to be erased form complete erase groups. Missing such checks
will lead to erasing extra data on the device.

This commit will:
a. If the device support the Trim command, use the Trim command to
perform the erase operations for eMMC devices.

According to the spec:
Unlike the Erase command, the Trim function applies the erase operation to
write blocks instead of erase groups.

b. If the device does not support the Trim command, use the Erase command
to erase the data in the erase groups. And write zeros to those blocks
that cannot form a complete erase group.

Ruiyu Ni 7111e46fde MdeModulePkg/NvmExpressDxe: Notify NVME HW when system reset happens
Per NVM Express Spec, software should notify NVME HW when shutdown
occurs.

The NVME controller requires notification for shutdown as part of
its management of internal structures. Even with FUA, failing to
notify the NVME controller to shutdown power off causes the NVME
controller to take quite some time to organize its tables on the
next power on. This time exceeds the normal timeout, so we would
fail to boot the NVME disk.

The host should set the Shutdown Notification (CC.SHN) field to 01b
to indicate a normal shutdown operation. The controller indicates

Star Zeng 4cf3f37c87 MdeModulePkg SerialDxe: Process timeout consistently in SerialRead
https://lists.01.org/pipermail/edk2-devel/2017-July/012385.html
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.

Star Zeng ecf85eb24c MdeModulePkg PiSmmCoreMemoryAllocLib: Fix a FreePool() assertion issue
When PiSmmCore links against PeiDxeDebugLibReportStatusCode, the code
flow below will cause a FreePool() assertion issue.

PiSmmCoreMemoryAllocationLibConstructor() ->
SmmInitializeMemoryServices() ->
DEBUG ((DEBUG_INFO, "SmmAddMemoryRegion\n")) in SmmAddMemoryRegion() ->
DebugPrint() -> REPORT_STATUS_CODE_EX() -> ReportStatusCodeEx() ->
AllocatePool()/FreePool(PiSmmCoreMemoryAllocLib) ->
ASSERT() at Head = CR (Buffer, POOL_HEAD, Data, POOL_HEAD_SIGNATURE)
  in CoreFreePoolI() of DxeCore Pool.c

It is because at the point of FreePool() in the code flow above,
mSmmCoreMemoryAllocLibSmramRanges/mSmmCoreMemoryAllocLibSmramRangeCount
are not been initialized yet, the FreePool() will be directed to
gBS->FreePool(), that is wrong.

This patch is to temporarily use BootServicesData to hold the
SmramRanges data before calling SmmInitializeMemoryServices().

In general, this is called a Babble Error. When a device sends more
data than the TD Transfer Size bytes (TD Babble), unexpected activity
that persists beyond a specified point in a (micro)frame (Frame Babble),
or a packet greater than Max Packet Size (Packet Babble), the host

The SATA spec mandates that link detection by the PHY completes within
10 ms after receiving a reset signal. However, there is no obligation
to uphold this requirement at the driver end as strictly as we do, and
as it turns out, some combinations of host and device (e.g., Samsung
850 EVO connected to a LeMaker Cello) are only borderline compliant,
which means the device is not detected reliably.

So let's allow for a bit of margin, and increase the PHY detect timeout
value to 15 ms.

Change since v3:
1) Fixed issue when Attributes = EFI_OPEN_PROTOCOL_TEST_PROTOCOL
and Inteface = NULL case. [Reported by:star.zeng at intel.com]

Change Since v2:
1) Modified to use EFI_ERROR to get status code

Change since v1:
1) Fixed typo protocal to protocol
2) Fixed coding style

Modified source code to update Interface as per spec.
1) In case of Protocol is un-supported, interface should be returned NULL.
2) In case of any error, interface should not be modified.
3) In case of Test Protocol, interface is optional.

Star Zeng c01f13d52a MdeModulePkg: Enhance the debug message for InstallProtocolInterface
Current code is using debug message like below for
InstallProtocolInterface.
InstallProtocolInterface: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX XXX

User could not know whether the installation is failed or not by the
debug message, for example, the code below does not initialize Handle
before calling InstallProtocolInterface, EFI_INVALID_PARAMETER will be
returned.
  EFI_HANDLE Handle;
  Status = gBS->InstallProtocolInterface (
                  &Handle,
                  &XXX,
                  EFI_NATIVE_INTERFACE,
                  XXX
                  );

This patch is to add additional debug message if the installation
is failed and specific debug message for the case that the input
handle is invalid.

Shi, Steven 322d827c0f MdeModulePkg: Fix use-after-free error in InstallConfigurationTable()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=601

When installing configuration table and the original
gDxeCoreST->ConfigurationTable[] buffer happen to be not big enough to
add a new table, the CoreInstallConfigurationTable() enter the branch
of line 113 in InstallConfigurationTable.c to free the old
gDxeCoreST->ConfigurationTable[] buffer and allocate a new bigger one.
The problem happens at line 139 CoreFreePool(), which is to free the
old gDxeCoreST->ConfigurationTable[] buffer. The CoreFreePool()'s
behavior is to free the buffer firstly, then call the
InstallMemoryAttributesTableOnMemoryAllocation (PoolType) to update
the EfiRuntimeServices type memory info, the
CoreInstallConfigurationTable() will be re-entered by CoreFreePool()
in its calling stack, then use-after-free read error will happen at
line 59 of InstallConfigurationTable.c and use-after-free write error
will happen at line 151 and 152 of InstallConfigurationTable.c.

The patch is to update System table to the new table pointer before
calling CoreFreePool() to free the old table.

The case above is in DxeCore, but not in PiSmmCore.
The change in PiSmmCore is to be consistent with DxeCore.

Ruiyu Ni b659b503fa MdeModulePkg/UsbBus: Fix system hang when failed to uninstall UsbIo
When "reconnect -r" is typed in shell, UsbFreeInterface() is called
to uninstall the UsbIo and DevicePath. But When a UsbIo is opened
by a driver and that driver rejects to close the UsbIo in Stop(),
the uninstall doesn't succeed.
But UsbFreeInterface () frees the DevicePath memory without check
whether the uninstall succeeds.
It leads to the DXE core database contain a DevicePath instance but
that instance's memory is freed.
Assertion happens when someone calls InstallProtocol(DevicePath)
because the InstallProtocol() checks all DevicePath instance to
find whether the same one exits in database.

We haven't seen any USB device driver which rejects to close UsbIo
in Stop(), but it's very likely.

Though this value won't affect the functionality, since it will be masked

This commit adds additional logic to avoid reading undefined content.

Jiewen Yao d1fddc4533 MdeModulePkg/Include: Add IOMMU protocol definition.
This protocol is to abstract DMA access from IOMMU.
1) Intel "DMAR" ACPI table.
2) AMD "IVRS" ACPI table
3) ARM "IORT" ACPI table.

There might be multiple IOMMU engines on one platform.
For example, one for graphic and one for rest PCI devices
(such as ATA/USB).
All IOMMU engines are reported by one ACPI table.

All IOMMU protocol provider should be based upon ACPI table.
This single IOMMU protocol can handle multiple IOMMU engines on one system.

This IOMMU protocol provider can use UEFI device path to distinguish
if the device is graphic or ATA/USB, and find out corresponding
IOMMU engine.

The IOMMU protocol provides 2 capabilities:
A) Set DMA access attribute - such as write/read control.
B) Remap DMA memory - such as remap above 4GiB system memory address
to below 4GiB device address.
It provides AllocateBuffer/FreeBuffer/Map/Unmap for DMA memory.
The remapping can be static (fixed at build time) or dynamic (allocate
at runtime).

4) AMD "SEV" feature.
We can have an AMD SEV specific IOMMU driver to produce IOMMU protocol,
and manage SEV bit.
