NetworkPkg/IScsiDxe: check IScsiHexToBin() return values

IScsiDxe (that is, the initiator) receives two hex-encoded strings from

- CHAP_C, where the target challenges the initiator,

- CHAP_R, where the target answers the challenge from the initiator (in
  case the initiator wants mutual authentication).

Accordingly, we have two IScsiHexToBin() call sites:

- At the CHAP_C decoding site, check whether the decoding succeeds. The
  decoded buffer ("AuthData->InChallenge") can accommodate 1024 bytes,
  which is a permissible restriction on the target, per
  <https://tools.ietf.org/html/rfc7143#section-12.1.3>. Shorter challenges
  from the target are acceptable.

- At the CHAP_R decoding site, enforce that the decoding both succeed, and
  provide exactly ISCSI_CHAP_RSP_LEN bytes. CHAP_R contains the digest
  calculated by the target, therefore it must be of fixed size. We may
  only call IScsiCHAPAuthTarget() if "TargetRsp" has been fully populated.

(1) If the *subject sequence* in "HexStr" is empty, the function returns
    EFI_SUCCESS (with "BinLength" set to 0 on output). Such inputs should
    be rejected.

(2) The function mis-handles a "HexStr" that ends with a stray nibble. For
    example, if "HexStr" is "0xABC", the function decodes it to the bytes
    {0xAB, 0x0C}, sets "BinLength" to 2 on output, and returns
    EFI_SUCCESS. Such inputs should be rejected.

(3) If an invalid hex char is found in "HexStr", the function treats it as
    end-of-hex-string, and returns EFI_SUCCESS. Such inputs should be
    rejected.

All of the above cases are remotely triggerable, as shown in a subsequent

the initiator is not immediately compromised, incorrectly parsing CHAP_R

Extend the interface contract of IScsiHexToBin() with
EFI_INVALID_PARAMETER, for reporting issues (1) through (3), and implement
the new checks.

  BinLength * 2 + 3

Rewrite the calculation using SafeIntLib.

While at it, change the type of the "Index" variable from UINTN to UINT32.
The largest "Index"-based value that we calculate is

  Index * 2 + 2                                (with (Index == BinLength))

Because the patch makes

  BinLength * 2 + 3

safe to calculate in UINT32, using UINT32 for

  Index * 2 + 2                                (with (Index == BinLength))

The integer overflows that this patch fixes are theoretical; a subsequent
patch in the series will audit the IScsiBinToHex() call sites, and show
that none of them can fail.

Laszlo Ersek [Wed, 9 Jun 2021 15:57:31 +0000 (17:57 +0200)]
OvmfPkg/PlatformCI: bump QEMU choco package version to 2021.5.5

We currently require QEMU choco package version 2020.08.14 (from commit
3ab9d60fcbe7), in "OvmfPkg/PlatformCI/.azurepipelines/Windows-VS2019.yml".
Said package version references the following URLs:

https://community.chocolatey.org/packages/Qemu/2020.08.14#files
-> https://qemu.weilnetz.de/w32/qemu-w32-setup-20200814.exe
-> https://qemu.weilnetz.de/w64/qemu-w64-setup-20200814.exe

These URLs no longer work; Stefan Weil seems to have moved the binaries to
the following archive directories:

- https://qemu.weilnetz.de/w32/2020/
- https://qemu.weilnetz.de/w64/2020/

In theory, the old QEMU choco packages should be fixed (their powershell
scripts should be updated to reference the new URLs on Stefan Weil's
website). However, this PlatformCI issue is blocking the merging of the
security fix for TianoCore#3356, so getting PlatformCI functional again is
urgent. Let's bump our QEMU choco package requirement to 2021.5.5, whose
URLs work, for now.

(Currently we cannot use any other choco package version, as Stefan's
directories <https://qemu.weilnetz.de/w32> and
<https://qemu.weilnetz.de/w64>, without any further subdirectories, only
offer the 20210505 EXE files.)

OvmfPkg: restrict XenPlatformLib to BdsDxe in the IA32, IA32X64, X64 DSCs

The "OvmfPkg/Library/PlatformBootManagerLib/PlatformBootManagerLib.inf"

  OvmfPkg/OvmfPkgIa32.dsc
  OvmfPkg/OvmfPkgIa32X64.dsc
  OvmfPkg/OvmfPkgX64.dsc
  OvmfPkg/OvmfXen.dsc

The Xen customizations are very light-weight in this
PlatformBootManagerLib instance. Isolating them statically, for the sake
of the first three DSC files, would save negligible binary code size, and
would likely worsen code complexity (by way of introducing new internal
interfaces) or blow up source code size (by duplicating almost the entire
lib instance source code). So for now, keep this one bit of Xen dynamism
even on QEMU.

However, because it's only PlatformBootManagerLib now that uses
XenPlatformLib (for the above-stated enlightenment), restrict the
XenPlatformLib class resolution in the first three DSC files to the only
DXE driver that consumes PlatformBootManagerLib (and therefore
XenPlatformLib): BdsDxe. This will cause a build failure later if someone
attempts to call a XenPlatformLib API (that is, tries to re-introduce Xen
enlightenment) in a different module in these non-Xen DSC files.

    InstallQemuFwCfgTables [QemuFwCfgAcpi.c]
      ...

eliminating the sub-trees highlighted with "*".

There are two consequences:

(1) Xen compatibility is removed from the ACPI platform driver of the
   historical OvmfPkg* platforms.

(2) The ACPI tables that are statically built into OVMF (via

    particular, OVMF's own runtime preparation of the MADT and SSDT is

Because of (2), remove the "OvmfPkg/AcpiTables/AcpiTables.inf" module as
well -- and then the ACPITABLE build rule too.

Note that (2) only removes effectively dead code; the QEMU ACPI

It can be downloaded and installed in Windows/Linux/Mac OS.
CLANG8ELF tool chain is added to generate ELF image, and convert to PE/COFF.
On Windows OS, set CLANG_HOST_BIN=n, set CLANG8_BIN=LLVM installed directory
For example:
  set CLANG_HOST_BIN=n # use windows nmake
  set CLANG8_BIN=C:\Program Files\LLVM\bin\
On Linux/Mac, set CLANG8_BIN=LLVM installed directory

This tool chain can be used to compile the firmware code. On windows OS,
Visual Studio is still required to compile BaseTools C tools and nmake.exe.
On Linux/Mac OS, gcc is used to compile BaseTools C tools. make is used
for makefile.

This tool chain is verified on OVMF Ia32, X64 and Ia32X64 to boot Shell.
This tool chain is verified in Windows/Linux and Mac OS.

IntelFsp2WrapperPkg: Remove microcode related PCDs

IntelFsp2WrapperPkg defines following PCDs:
  PcdCpuMicrocodePatchAddress
  PcdCpuMicrocodePatchRegionSize
  PcdFlashMicrocodeOffset

But the PCD name caused confusion because UefiCpuPkg defines:
  PcdCpuMicrocodePatchAddress
  PcdCpuMicrocodePatchRegionSize

PcdCpuMicrocodePatchAddress in IntelFsp2WrapperPkg means the base
address of the FV that holds the microcode.
PcdCpuMicrocodePatchAddress in UefiCpuPkg means the address of the
microcode.

The relationship between the PCDs is:
IntelFsp2WrapperPkg.PcdCpuMicrocodePatchAddress
 +  IntelFsp2WrapperPkg.PcdFlashMicrocodeOffset
 == UefiCpuPkg.PcdCpuMicrocodePatchAddress

IntelFsp2WrapperPkg.PcdCpuMicrocodePatchRegionSize
 -  IntelFsp2WrapperPkg.PcdFlashMicrocodeOffset
 == UefiCpuPkg.PcdCpuMicrocodePatchRegionSize

To avoid confusion and actually the PCDs in IntelFsp2WrapperPkg
are only used by a sample FSP-T wrapper, this patch removes
the 3 PCDs defined in IntelFsp2WrapperPkg.

The FSP-T wrapper is updated to directly use the ones in UefiCpuPkg.

2 years agoUefiCpuPkg/MpInitLib: Allocate a separate SEV-ES AP reset stack area

UefiCpuPkg/MpInitLib: Allocate a separate SEV-ES AP reset stack area

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3324

The SEV-ES stacks currently share a page with the reset code and data.
Separate the SEV-ES stacks from the reset vector code and data to avoid
possible stack overflows from overwriting the code and/or data.

When SEV-ES is enabled, invoke the GetWakeupBuffer() routine a second time
to allocate a new area, below the reset vector and data.

Both the PEI and DXE versions of GetWakeupBuffer() are changed so that
when PcdSevEsIsEnabled is true, they will track the previous reset buffer
allocation in order to ensure that the new buffer allocation is below the
previous allocation. When PcdSevEsIsEnabled is false, the original logic
is followed.

ArmPkg/ArmGic: Fix maximum number of interrupts in GICv3

Bugzilla: 3415 (https://bugzilla.tianocore.org/show_bug.cgi?id=3415)

The GICv3 architecture supports up to 1020 ordinary interrupt
lines. The actual number of interrupts supported is described by the
ITLinesNumber field in the GICD_TYPER register. The total number of
implemented registers is normally calculated as
32*(ITLinesNumber+1). However, maximum value (0x1f) is a special case
since that would indicate that 1024 interrupts are implemented.

Add handling for this special case in ArmGicGetMaxNumInterrupts.
