Alcantara, Paulo 00f18da1ca OvmfPkg: Add RAM disk support
Currently booting off of a RAM disk is not supported by
IntelFrameWorkModulePkg BDS, however on systems without writable
disks, the RAM disk can be made useful when loading raw HDD images
into it -- specially the ones with a FAT32 partition on which files
can be natively accessed by system firmware.

This patch adds RamDiskDxe driver by default in OVMF platform.

James Bottomley f5404a3eba OvmfPkg: Increase the maximum size for Authenticated variables
During real world testing I was getting an error with too many entries
in db: On my Secure boot laptop, I currently have seven certificates:
two Microsoft ones, Three Kernel ones from various distributions, my
own Secure Key and a temporary test key.  That gives a total EFI
Signature List size of 8317 which is over the 0x2000 maximum.

Fix this by setting the PcdMaxAuthVariableSize to 0x2800 (10K) which
isn't much of an increase but allows for 9-10 certificates.

Laszlo Ersek 7e5b1b670c OvmfPkg: PlatformPei: determine the 64-bit PCI host aperture for X64 DXE
The main observation about the 64-bit PCI host aperture is that it is the
highest part of the useful address space. It impacts the top of the GCD
memory space map, and, consequently, our maximum address width calculation
for the CPU HOB too.

Thus, modify the GetFirstNonAddress() function to consider the following
areas above the high RAM, while calculating the first non-address (i.e.,
the highest inclusive address, plus one):

- the memory hotplug area (optional, the size comes from QEMU),

- the 64-bit PCI host aperture (we set a default size).

While computing the first non-address, capture the base and the size of
the 64-bit PCI host aperture at once in PCDs, since they are natural parts
of the calculation.

(Similarly to how PcdPciMmio32* are not rewritten on the S3 resume path
(see the InitializePlatform() -> MemMapInitialization() condition), nor
are PcdPciMmio64*. Only the core PciHostBridgeDxe driver consumes them,
through our PciHostBridgeLib instance.)

Set 32GB as the default size for the aperture. Issue#59 mentions the
NVIDIA Tesla K80 as an assignable device. According to nvidia.com, these
cards may have 24GB of memory (probably 16GB + 8GB BARs).

As a strictly experimental feature, the user can specify the size of the
aperture (in MB) as well, with the QEMU option

  -fw_cfg name=opt/ovmf/X-PciMmio64Mb,string=65536

The "X-" prefix follows the QEMU tradition (spelled "x-" there), meaning
that the property is experimental, unstable, and might go away any time.
Gerd has proposed heuristics for sizing the aperture automatically (based
on 1GB page support and PCPU address width), but such should be delayed to
a later patch (which may very well back out "X-PciMmio64Mb" then).

For "everyday" guests, the 32GB default for the aperture size shouldn't
impact the PEI memory demand (the size of the page tables that the DXE IPL
PEIM builds). Namely, we've never reported narrower than 36-bit addresses;
the DXE IPL PEIM has always built page tables for 64GB at least.

For the aperture to bump the address width above 36 bits, either the guest
must have quite a bit of memory itself (in which case the additional PEI
memory demand shouldn't matter), or the user must specify a large aperture
manually with "X-PciMmio64Mb" (and then he or she is also responsible for
giving enough RAM to the VM, to satisfy the PEI memory demand).

Laszlo Ersek c47ed6fcb5 OvmfPkg: match PCI config access to machine type (if not USE_OLD_PCI_HOST)
If USE_OLD_PCI_HOST is FALSE, then we switch all executable module types
supported by DxePciLibI440FxQ35 to the following library instance stack:

  BasePciSegmentLibPci  [class: PciSegmentLib]
    DxePciLibI440FxQ35  [class: PciLib]
      BasePciCf8Lib     [class: PciCf8Lib]
      BasePciExpressLib [class: PciExpressLib]

Every module will select 0xCF8 vs. ECAM based on the OVMF platform type
(i440fx or Q35). Notably, MdeModulePkg/Bus/Pci/PciHostBridgeDxe is among
the affected drivers.

The BasePciExpressLib instance is where the PcdPciExpressBaseAddress PCD
fills its original role.

Laszlo Ersek 7b8fe63561 OvmfPkg: PlatformPei: enable PCIEXBAR (aka MMCONFIG / ECAM) on Q35
The comments in the code should speak for themselves; here we note only
two facts:

- The PCI config space writes (to the PCIEXBAR register) are performed
  using the 0xCF8 / 0xCFC IO ports, by virtue of PciLib being resolved to
  BasePciLibCf8. (This library resolution will permanently remain in place
  for the PEI phase.)

- Since PCIEXBAR counts as a chipset register, it is the responsibility of
  the firmware to reprogram it at S3 resume. Therefore
  PciExBarInitialization() is called regardless of the boot path. (Marcel
  recently posted patches for SeaBIOS that implement this.)

This patch suffices to enable PCIEXBAR (and the dependent ACPI table
generation in QEMU), for the sake of "PCIeHotplug" in the Linux guest:

  ACPI: MCFG 0x000000007E17F000 00003C
        (v01 BOCHS  BXPCMCFG 00000001 BXPC 00000001)
  PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0x80000000-0x8fffffff]
       (base 0x80000000)
  PCI: MMCONFIG at [mem 0x80000000-0x8fffffff] reserved in E820
  acpi PNP0A08:00: _OSC: OS supports
                   [ExtendedConfig ASPM ClockPM Segments MSI]
  acpi PNP0A08:00: _OSC: OS now controls
                   [PCIeHotplug PME AER PCIeCapability]

In the following patches, we'll equip the core PCI host bridge / root
bridge driver and the rest of DXE as well to utilize ECAM on Q35.

Laszlo Ersek 75f4533119 OvmfPkg: resolve PciSegmentLib

That driver depends on the PciSegmentLib class. Edk2 offers four
instances:

(1) MdePkg/Library/UefiPciSegmentLibPciRootBridgeIo/

    Inappropriate here because it consumes
    EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL, but
    "MdeModulePkg/Bus/Pci/PciHostBridgeDxe" needs the library class for
    producing that protocol.

(2) MdePkg/Library/PeiPciSegmentLibPciCfg2/

    Restricted to PEIM, SEC, and PEI_CORE client modules.

(3) MdePkg/Library/DxePciSegmentLibEsal/

    "uses ESAL services to perform PCI Configuration cycles"

(4) MdePkg/Library/BasePciSegmentLibPci/

    A simple BASE library instance that sits on top of PciLib. This is our
    choice. We can resolve PciSegmentLib to this instance for all module
    types.

Going forward, two modules will need to know about the aperture:
PlatformPei (as before), and OVMF's upcoming PciHostBridgeLib instance
(because the core PciHostBridgeDxe driver requires the library to state
the exact apertures for all root bridges).

On QEMU, all root bridges share the same MMIO aperture, hence one pair of
PCDs suffices.

Laszlo Ersek 1fea9ddb4e OvmfPkg: execute option ROM images regardless of Secure Boot
Change the image verification policy for option ROM images to 0x00
(ALWAYS_EXECUTE).

While this may not be a good idea for physical platforms (see e.g.
<https://trmm.net/Thunderstrike>), on the QEMU platform the benefits seem
to outweigh the drawbacks:

- For QEMU's virtual PCI devices, and for some assigned PCI devices, the
  option ROMs come from host-side files, which can never be rewritten from
  within the guest. Since the host admin has full control over a guest
  anyway, executing option ROMs that originate from host-side files
  presents no additional threat to the guest.

- For assigned physical PCI devices with option ROMs, the argument is not
  so clear-cut. In theory a setup could exist where:

  - the host-side UEFI firmware (with DENY_EXECUTE_ON_SECURITY_VIOLATION)
    rejects the option ROM of a malicious physical PCI device, but

  - when the device is assigned to the guest, OVMF executes the option ROM
    in the guest,

  - the option ROM breaks out of the guest (using an assumed QEMU
    vulnerability) and gains QEMU user privileges on the host.

  However, in order to escalate as far as it would happen on the bare
  metal with ALWAYS_EXECUTE (i.e., in order to gain firmware-level access
  on the host), the malicious option ROM would have to break through (1)
  QEMU, (2) traditional UID and GID based privilege separation on the
  host, (3) sVirt (SELinux) on the host, (4) the host OS - host firmware
  boundary. This is not impossible, but not likely enough to discourage
  the use cases below.

- This patch makes it possible to use unsigned iPXE network drivers that
  QEMU presents in the option ROMs of virtual NICs and assigned SR-IOV
  VFs, even if Secure Boot is in User Mode or Deployed Mode.

- The change also makes it possible to execute unsigned, outdated
  (revoked), or downright malicious option ROMs of assigned physical
  devices in guests, for corporate, entertainment, academia, or security
  research purposes.

Laszlo Ersek 65d2bf4223 OvmfPkg: inherit Image Verification Policy defaults from SecurityPkg
Secure Boot support was originally addded to OvmfPkg on 2012-Mar-09, in
SVN r13093 (git 8cee3de7e9), titled

  OvmfPkg: Enable secure-boot support when SECURE_BOOT_ENABLE==TRUE

At that time the image verification policies in
SecurityPkg/SecurityPkg.dec were:

- option ROM image:      0x00 (ALWAYS_EXECUTE)
- removable media image: 0x05 (QUERY_USER_ON_SECURITY_VIOLATION)
- fixed media image:     0x05 (QUERY_USER_ON_SECURITY_VIOLATION)

The author of SVN r13093 apparently didn't want to depend on the
SecurityPkg defaults for the latter two image origins, plus the
ALWAYS_EXECUTE policy for option ROM images must have been deemed too lax.
For this reason SVN r13093 immediately spelled out 0x05
(QUERY_USER_ON_SECURITY_VIOLATION) within OvmfPkg for all three image
origins.

Fast forward to 2013-Aug-28: policy 0x05
(QUERY_USER_ON_SECURITY_VIOLATION) had been forbidden in the UEFI spec,
and SVN r14607 (git db44ea6c4e) reflected this in the source code:

- The policies for the latter two image origins were switched from 0x05 to
  0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION) in SecurityPkg,

- the patch changed the default policy for option ROM images too, from
  0x00 (ALWAYS_EXECUTE) to 0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION),

- any other client DSC files, including OvmfPkg's, underwent a whole-sale
  0x05 (QUERY_USER_ON_SECURITY_VIOLATION) -> 0x04
  (DENY_EXECUTE_ON_SECURITY_VIOLATION) replacement too.

The practical result of that patch for OvmfPkg was that the explicit 0x04
settings would equal the strict SecurityPkg defaults exactly.

And that's what we have today: the "override the default values from
SecurityPkg" comments in OvmfPkg's DSC files are stale, in practice.

It is extremely unlikely that SecurityPkg would change the defaults from
0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION) any time in the future, so let's
just inherit those in OvmfPkg.

Laszlo Ersek bb0f18b0bc OvmfPkg: any AP in SMM should not wait for the BSP for more than 100 ms
This patch complements the previous one, "OvmfPkg: use relaxed AP SMM
synchronization mode". While that patch focuses on the case when the SMI
is raised synchronously by the BSP, on the BSP:

  BSPHandler()             [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
    SmmWaitForApArrival()  [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
      IsSyncTimerTimeout() [UefiCpuPkg/PiSmmCpuDxeSmm/SyncTimer.c]

this patch concerns itself with the case when it is one of the APs that
raises (and sees delivered) the synchronous SMI:

  APHandler()            [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
    IsSyncTimerTimeout() [UefiCpuPkg/PiSmmCpuDxeSmm/SyncTimer.c]

Namely, in APHandler() the AP waits for the BSP to enter SMM regardless of
PcdCpuSmmSyncMode, for PcdCpuSmmApSyncTimeout microseconds (the default
value is 1 second). If the BSP doesn't show up in SMM within that
interval, then the AP brings it in with a directed SMI, and waits for the
BSP again for PcdCpuSmmApSyncTimeout microseconds.

Although during boot services, SmmControl2DxeTrigger() is only called by
the BSP, at runtime the OS can invoke runtime services from an AP (it can
even be forced with "taskset -c 1 efibootmgr"). Because on QEMU
SmmControl2DxeTrigger() only raises the SMI for the calling processor (BSP
and AP alike), the first interval above times out invariably in such cases
-- the BSP never shows up before the AP calls it in.

In order to mitigate the performance penalty, decrease
PcdCpuSmmApSyncTimeout to one tenth of its default value: 100 ms. (For
comparison, Vlv2TbltDevicePkg sets 1 ms.)

NOTE: once QEMU becomes capable of synchronous broadcast SMIs, this patch
and the previous one ("OvmfPkg: use relaxed AP SMM synchronization mode")
should be reverted, and SmmControl2DxeTrigger() should be adjusted
instead.

Paolo Bonzini 9b1e378811 OvmfPkg: use relaxed AP SMM synchronization mode
Port 0xb2 on QEMU only sends an SMI to the currently executing processor.
The SMI handler, however, and in particular SmmWaitForApArrival, currently
expects that SmmControl2DxeTrigger triggers an SMI IPI on all processors
rather than just the BSP.  Thus all SMM invocations loop for a second (the
default value of PcdCpuSmmApSyncTimeout) before SmmWaitForApArrival sends
another SMI IPI to the APs.

With the default SmmCpuFeaturesLib, 32-bit machines must broadcast SMIs
because 32-bit machines must reset the MTRRs on each entry to system
management modes (they have no SMRRs).  However, our virtual platform
does not have problems with cacheability of SMRAM, so we can use "directed"
SMIs instead.  To do this, just set gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmSyncMode
to 1 (aka SmmCpuSyncModeRelaxedAp).  This fixes SMM on multiprocessor virtual
machines.

Laszlo Ersek 896d3dcf25 OvmfPkg: set gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmEnableBspElection to FALSE
Explanation from Michael Kinney:

  This PCD allows a platform to provide PlatformSmmBspElection() in a
  platform specific SmmCpuPlatformHookLib instance to decide which CPU
  gets elected to be the BSP in each SMI.

  The SmmCpuPlatformHookLibNull [instance] always returns EFI_NOT_READY
  for that function, which makes the module behave the same as the PCD
  being set to FALSE.

  The default is TRUE, so the platform lib is always called, so a platform
  developer can implement the hook function and does not have to also
  change a PCD setting for the hook function to be active.

  A platform that wants to eliminate the call to the hook function
  [altogether] can set the PCD to FALSE.

  So for OVMF, I think it makes sense to set this PCD to FALSE in the DSC
  file.

Laszlo Ersek decb365b00 OvmfPkg: select LocalApicLib instance with x2apic support
Although neither LocalApicLib instance is suitable for runtime DXE drivers
(because they access the APIC at the physical address retrieved from
either MSR_IA32_APIC_BASE_ADDRESS or PcdCpuLocalApicBaseAddress), they are
suitable for SMM drivers -- SMM drivers are not influenced by the runtime
OS's virtual address map.

PiSmmCpuDxeSmm links against LocalApicLib. 64-bit Linux guests tend to
enable x2apic mode even in simple VCPU configurations (e.g., 4 sockets, 1
core/socket, 1 thread/core):

  [    0.028173] x2apic enabled

If PiSmmCpuDxeSmm was linked with the BaseXApicLib instance (i.e., with no
x2apic support), then the next runtime service call that is backed by an
SMM driver triggers the following ASSERT in BaseXApicLib (because the
latter notices that x2apic has been enabled, which it doesn't support):

  ASSERT .../UefiCpuPkg/Library/BaseXApicLib/BaseXApicLib.c(263):
  ApicBaseMsr.Bits.Extd == 0

It is reasonable to give all LocalApicLib client modules in OVMF the same
level of x2apic support, hence resolve LocalApicLib globally to
BaseXApicX2ApicLib. This will not be conditional on -D SMM_REQUIRE,
because BaseXApicX2ApicLib is compatible with BaseXApicLib in any
environment where the latter can be used.

Laszlo Ersek 67d8659474 OvmfPkg: LockBox: use SMM stack with -D SMM_REQUIRE
During DXE, drivers save data in the LockBox. A save operation is layered
as follows:

- The unprivileged driver wishing to store data in the LockBox links
  against the "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxDxeLib.inf"
  library instance.

  The library allows the unprivileged driver to format requests for the
  privileged SMM LockBox driver (see below), and to parse responses.

  We apply this resolution for DXE_DRIVER modules.

- The privileged SMM LockBox driver is built from
  "MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf". This driver
  has module type DXE_SMM_DRIVER and can access SMRAM.

  The driver delegates command parsing and response formatting to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxSmmLib.inf".

  Therefore we include this DXE_SMM_DRIVER in the build, and apply said
  resolution specifically to it.

  (Including the driver requires us to resolve a few of other library
  classes for DXE_SMM_DRIVER modules.)

- In PEI, the S3 Resume PEIM (UefiCpuPkg/Universal/Acpi/S3Resume2Pei)
  retrieves data from the LockBox. It is capable of searching SMRAM
  itself.

  We resolve LockBoxLib to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" specifically
  for this one PEIM.

Laszlo Ersek f25cb158ea OvmfPkg: pull in the SMM IPL and SMM core
"MdeModulePkg/Core/PiSmmCore/PiSmmIpl.inf" (a DXE_RUNTIME_DRIVER)
implements the SMM Initial Program Loader. It produces
EFI_SMM_BASE2_PROTOCOL and EFI_SMM_COMMUNICATION_PROTOCOL, relying on:
- EFI_SMM_ACCESS2_PROTOCOL
  (provided by OvmfPkg/SmmAccess/SmmAccess2Dxe.inf),
- EFI_SMM_CONTROL2_PROTOCOL
  (provided by OvmfPkg/SmmControl2Dxe/SmmControl2Dxe.inf).

(The SMM IPL also depends on EFI_SMM_CONFIGURATION_PROTOCOL_GUID, but this
dependency is not enforced in the entry point. A protocol notify callback
is registered instead, hence we can delay providing that protocol via the
PiSmmCpuDxeSmm driver that is (to be) imported from UefiCpuPkg/.)

The SMM IPL loads the SMM core into SMRAM and executes it from there.
Therefore we add the SMM core to the build as well.

For the SMM core, a number of library classes need to be resolved.
Furthermore, each FDF file must provide the GenFds.py BaseTools utility
with a build rule for SMM_CORE; we copy the DXE_CORE's rule.

Laszlo Ersek 9d560947f6 OvmfPkg: add PEIM for providing TSEG-as-SMRAM during PEI
"MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" is the
LockBoxLib instance with SMRAM access for the PEI phase.

Said library instance must, and can, access the LockBox data in SMRAM
directly if it is invoked before SMBASE relocation / SMI handler
installation. In that case, it only needs PEI_SMM_ACCESS_PPI from the
platform, and it doesn't depend on EFI_PEI_SMM_COMMUNICATION_PPI.

OVMF satisfies the description in SVN r18823 ("MdeModulePkg:
SmmLockBoxPeiLib: work without EFI_PEI_SMM_COMMUNICATION_PPI"): in OVMF,
only S3Resume2Pei links against SmmLockBoxPeiLib.

Therefore, introduce a PEIM that produces the PEI_SMM_ACCESS_PPI
interface, enabling SmmLockBoxPeiLib to work; we can omit including
"UefiCpuPkg/PiSmmCommunication/PiSmmCommunicationPei.inf".

The load / installation order of S3Resume2Pei and SmmAccessPei is
indifferent. SmmAccessPei produces the gEfiAcpiVariableGuid HOB during its
installation (which happens during PEI), but S3Resume2Pei accesses the HOB
only when the DXE IPL calls its S3RestoreConfig2 PPI member, as last act
of PEI.

MCH_SMRAM_D_LCK and MCH_ESMRAMC_T_EN are masked out the way they are, in
SmmAccessPeiEntryPoint() and SmramAccessOpen() respectively, in order to
prevent VS20xx from warning about the (otherwise fully intentional)
truncation in the UINT8 casts. (Warnings reported by Michael Kinney.)

Laszlo Ersek d20b06a3af OvmfPkg: disable no-exec DXE stack by default
(PcdSetNxForStack == TRUE) breaks a number of GRUB versions that, it turns
out, are still widely in use. Disable PcdSetNxForStack by default for now.
QEMU users can enable it dynamically using the micro-feature added in the
previous patch.

Laszlo Ersek c075d250f6 OvmfPkg: make PcdPropertiesTableEnable dynamic
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.

Laszlo Ersek ead7cb12d5 OvmfPkg: prevent code execution from DXE stack
SVN rev 18166 ("MdeModulePkg DxeIpl: Add stack NX support") enables
platforms to request non-executable stack for the DXE phase, by setting
PcdSetNxForStack to TRUE.

The PCD defaults to FALSE, because:

(a) A non-executable DXE stack is a new feature and causes changes in
    behavior. Some platform could rely on executing code from the stack.

(b) The code enabling NX in the DXE IPL PEIM enforces the

      PcdSetNxForStack ==> PcdDxeIplBuildPageTables

    implication for "64-bit PEI + 64-bit DXE" platforms, with a new
    ASSERT(). Some platform might not comply with this requirement
    immediately.

Regarding (a), in none of the OVMF builds do we try to execute code from
the stack.

Regarding (b):

- In the OvmfPkgX64.dsc build (which is where (b) applies) we simply
  inherit the PcdDxeIplBuildPageTables|TRUE default from
  "MdeModulePkg/MdeModulePkg.dec". Therefore we can set PcdSetNxForStack
  to TRUE.

- In OvmfPkgIa32X64.dsc, page tables are built by default for DXE. Hence
  we can set PcdSetNxForStack to TRUE.

- In OvmfPkgIa32.dsc, page tables used not to be necessary until now.
  After we set PcdSetNxForStack to TRUE in this patch, the DXE IPL will
  construct page tables even when it is built as part of OvmfPkgIa32.dsc,
  provided the (virtual) hardware supports both PAE mode and the XD bit.

Should this setting cause problems in a GPU (or other device) passthru
scenario, with a UEFI_DRIVER in the PCI option rom attempting to execute
code from the stack, the feature can be dynamically disabled on the QEMU
command line, with "-cpu <MODEL>,-nx".

Gary Ching-Pang Lin ab44a6e833 OvmfPkg: Add HttpBoot support
This commit introdues a new build option to OvmfPkg: HTTP_BOOT_ENABLE.
When HttpBoot is enabled, a new Network boot option will show in the
boot manager menu with the device path like this:

PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)/Uri()

It works like the PXE one but fetches the NBP from the given http
url instead of the tftp service.

A simple testing environment can be set up with the QEMU tap network
and dnsmasq + lighttpd.

Here is the example of the dnsmasq config:

  interface=<tap interface>
  dhcp-range=192.168.111.100,192.168.111.120,12h
  dhcp-option=60,"HTTPClient"
  dhcp-boot="http://<tap ip>/<efi file>"

It's similar to the PXE server settings except the tftp function is
disabled, the option 60 must be "HTTPClient", and the boot uri is a
http url.

This patch de-duplicates the logic added in commit

  OvmfPkg: PlatformPei: set SMBIOS entry point version dynamically

(git 37baf06b, SVN r17676) by hooking DetectSmbiosVersionLib into
SmbiosDxe.

Although said commit was supposed to work with SMBIOS 3.0 payloads from
QEMU, in practice that never worked, because the size / signature checks
in SmbiosVersionInitialization() would always fail, due to the SMBIOS 3.0
entry point being structurally different. Therefore this patch doesn't
regress OvmfPkg.
