Brijesh Singh 0a78d754ed OvmfPkg/VirtioLib: add VirtioMapAllBytesInSharedBuffer() helper function
The function can be used for mapping the system physical address to virtio
device address using VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer (). The
function helps with centralizing error handling, and it allows the caller
to pass in constant or other evaluated expressions for NumberOfBytes.

Brijesh Singh 878115261a OvmfPkg: introduce IOMMU-like member functions to VIRTIO_DEVICE_PROTOCOL
The patch extends VIRTIO_DEVICE_PROTOCOL to provide the following new
member functions:

- AllocateSharedPages : allocate a memory region suitable for sharing
   between guest and hypervisor (e.g ring buffer).

- FreeSharedPages: free the memory allocated using AllocateSharedPages ().

- MapSharedBuffer: map a host address to device address suitable to share
   with device for bus master operations.

- UnmapSharedBuffer: unmap the device address obtained through the
   MapSharedBuffer().

We're free to extend the protocol structure without changing the protocol
GUID, or bumping any protocol version fields (of which we currently have
none), because VIRTIO_DEVICE_PROTOCOL is internal to edk2 by design --
see the disclaimers in "VirtioDevice.h".

The patch implements Laszlo's recommendation [1].

Liming Gao 2f7f1e73c1 BaseTools: Add the missing -pie link option in GCC tool chain
https://bugzilla.tianocore.org/show_bug.cgi?id=671
GCC tool chain uses -fpie in CC_FLAGS. So, add -pie in DLINK_FLAGS.
More discussion in
https://lists.01.org/pipermail/edk2-devel/2017-August/013508.html

3.13 Options for Linking
========================
'-pie'
     Produce a position independent executable on targets that support
     it.  For predictable results, you must also specify the same set
     of options used for compilation ('-fpie', '-fPIE', or model
     suboptions) when you specify this linker option.

3.18 Options for Code Generation Conventions
============================================
'-fpie'
'-fPIE'
     These options are similar to '-fpic' and '-fPIC', but generated
     position independent code can be only linked into executables.
     Usually these options are used when '-pie' GCC option is used
     during linking.
     '-fpie' and '-fPIE' both define the macros '__pie__' and
     '__PIE__'. The macros have the value 1 for '-fpie' and 2 for
     '-fPIE'.

Ard Biesheuvel 6650d78558 ArmPkg/ArmDmaLib: remove dependency on UncachedMemoryAllocationLib
Now that ArmDmaLib no longer uses uncached mappings for short-lived
bounce buffers used for streaming DMA, the only place we allocate
uncached memory is in DmaAllocateBuffer (), which is used for static
mappings shared between the host and the device, e.g., for packet
descriptor rings etc.

There is no performance concern around such long lived mappings, and
so we can really do without the overhead of UncachedMemoryAllocationLib,
which is a sizable chunk of poorly maintained code that never actually
releases any memory, and despite the fact that it implements pool based
routines, it always performs page based allocations anyway.

So let's invoke the DXE services directly to manage memory attributes
on allocations, and keep track of the allocations in a linked list so
we can restore the attributes and free the memory properly after use.

Ard Biesheuvel cefbbb3d08 ArmVirtPkg: remove QemuVideoDxe from ArmVirtQemu and ArmVirtQemuKernel
One of the reasons for introducing virtio-gpu support to OvmfPkg and
ArmVirtpkg was the fact that under KVM virtualization on ARM, the
legacy VGA cannot be used reliably. This is due to an implementation
detail of QEMU+KVM, which remaps cached host memory into the guest
address space as a framebuffer behind a PCI BAR. Given that the purpose
of a memory mapped framebuffer is its side effects, such BARs should
never be mapped cacheable in the guest, and the mismatched attributes
between host and guest result in a loss of coherency, visible as
corruption in the framebuffer image.

This issue does not occur under TCG emulation, nor did we expect it to
actually bring down the guest under KVM, and so it was deemed harmless
to keep support for the VGA device as well. However, as it turns out,
the fact that the framebuffer BAR is mapped using device semantics by
default may result in unalignment faults when we use the ordinary string
copy routines on the contents. In theory, we could work around this by
remapping the BAR as write combining, but it appears the generic PCI
bus driver does not actually implement this.

So let's remove the QemuVideoDxe driver altogether. This may result
in loss of functionality for use cases that rely on the framebuffer
to be directly addressable (such as EFIFB), but given that this never
worked reliably under KVM in the first place, let's not let that stop
us from dropping support for it.

These fields are actually a GUID and DWORD respectively: the GUID identifies
the PDB to make it possible to verify that a given PDB matches the PE file,
and the DWORD is the "age" of the PDB which is simply a helper value that is
incremented by 1 by the linker every time the file is remade. Wiping the
GUID will cause PDB parsers (such as the MS DIA SDK that IDA and most other
tools use) to treat the PDB as a mismatch and refuse to load it.

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

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.

the data we are exchanging with the device.

Such corruption can only occur on bus master write, in which case we have
to invalidate the caches to ensure the CPU will see the data written to
memory by the device. In the bus master read case, we can simply clean
and invalidate at the same time, which may purge unrelated adjacent data
from the caches, but will not corrupt its contents.

Also, this double buffer does not necessarily have to be allocated from
uncached memory: by the same reasoning, we can perform cache invalidation
on an ordinary pool allocation as long as we take the same alignment
constraints into account.

So update our code accordingly: remove double buffering from the bus
master read path, and switch to a pool allocation for the double buffer.

Laszlo Ersek 5f0f5e90ae ArmVirtPkg/FdtPL011SerialPortLib: call PL011UartLib in all SerialPortLib APIs
With the SerialDxe change in commit 4cf3f37c87 ("MdeModulePkg SerialDxe:
Process timeout consistently in SerialRead", 2017-07-18), setting
EFI_SERIAL_INPUT_BUFFER_EMPTY in the "Control" output parameter, in the
GetControl() SerialPortLib function, is no longer a "small optimization".
Namely, due to the SerialDxe change, the GetOneKeyFromSerial() call in
TerminalDxe's TerminalConInTimerHandler() can take very long if the input
queue is empty, even if GetOneKeyFromSerial()'s return value causes the
loop to be exited right after, in the first iteration.

This issue causes a boot hang in ArmVirtQemu: with the input queue empty,
TerminalConInTimerHandler() takes so long to return that, by the time it
returns, there's another execution queued already (due to the associated
timer event being signaled meanwhile). The boot process is stuck in the
timer event handler.

Therefore even the first GetOneKeyFromSerial() iteration must be prevented
in TerminalConInTimerHandler() if the input queue is empty, and that
requires implementing GetControl() for real.

Implement the SetAttributes(), SetControl() and GetControl() APIs (of
SerialPortExtLib origin) in FdtPL011SerialPortLib with calls to matching
PL011UartLib functions. This follows the example of
"ArmPlatformPkg/Library/PL011SerialPortLib" and also matches Star's
original idea under [1].

The patch can be considered a continuation of commit ad7f6bc2e1
("ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg",
2015-11-26), based on the mailing list threads [1] [2] [3].

Laszlo Ersek ca56256d5e OvmfPkg/build.sh: select the GCC49 toolchain settings for gcc-7.*
When UefiCpuPkg/MpInitLib is built for X64 with gcc-7, using the DEBUG
build target and the GCC5 toolchain settings, a C-language assignment is
miscompiled such that the initial AP startup hangs in CpuMpPei (X64) or
CpuDxe (Ia32X64). See <https://bugzilla.tianocore.org/show_bug.cgi?id=671>
for a detailed analysis of the symptoms, and for mailing list links.

This issue has been reported several times (one example is
<https://bugzilla.tianocore.org/show_bug.cgi?id=657>). Until we (or the
upstream gcc developers) figure out how to dissuade gcc-7 from the
miscompilation, pick the GCC49 toolchain in "build.sh" for gcc-7.*.

Although everyone is encouraged to review patches and add their
Reviewed-by reply for a patch, with the Package Reviewer role we
identify additional community members that will be Cc'd for patches
made to a package.

A distinction between a Package Maintainer and Reviewer is that
Maintainers will always have source control push access to the package
whereas Reviewers will not. (The Reviewer may have push access if they
are also Package Maintainer for another package.)

Currently we have an limit of 2 Package Maintainers per package, but
the Package Maintainers for each package decide how to manage the
Package Reviewer list.

Marvin.Haeuser@outlook.com 9062381a8c MdePkg/BaseLib: Update internal LinkedList verifications.
1) Replace InternalBaseLibIsNodeInList() with
   InternalBaseLibIsListValid().
   - The verification whether Node is within the doubly-linked List
     is now done by IsNodeInList().
   - Whether the list is valid is returned.

2) The comments within InsertHeadList() and InsertTailList() stated
   that it is checked whether Entry is not part of the doubly-linked
   list. This was not done as argument 3 of
   InternalBaseLibIsNodeInList() indicated whether the check is done,
   not whether to check if the node is or is not in the list. This
   has been fixed by using IsNodeInList() for the ASSERTs.

V2:
  - Fix IsListEmpty() to ASSERT when the passed list is invalid.
  - Introduce the VERIFY_IS_NODE_IN_LIST() macro to only verify whether the
    passed node is part of the list when PcdVerifyNodeInList is TRUE.

V3:
  - Introduce the ASSERT_VERIFY_NODE_IN_VALID_LIST() macro which,
    depending on the value of PcdVerifyNodeInList, verifies whether
    SecondEntry is or is not part of the same doubly-linked list as
    FirstEntry and unconditionally verifies whether the doubly-linked
    list FirstEntry is part of is valid. This prevents
    InternalBaseLibIsListValid() from being called twice when a
    function ASSERTs via the result of IsNodeInList(), as it calls
    InternalBaseLibIsListValid() already.
  - Remove the VERIFY_IS_NODE_IN_LIST() macro in favor of
    ASSERT_VERIFY_NODE_IN_VALID_LIST().
