Tianocore BIOS setup authentication password patch

~ hucktech ~ Leave a comment

Jiewen Yao of Intel posted a V2 patch to the EDK2-devel list, adding new user authentication to Tianocore, including SMM interaction.

==== V2 ====
1) Add SmmCommunicationBufferProtocol dependency.
2) Cleanup header file and copyright to 2017.
3) Add missing UserAuthenticationSmm.uni.
4) Rename KeyLib.h/c to KeyService.h/c to avoid confusing.

This series patch adds password support in EDKII. This password based user authentication is to verify user when a user
wants to enter BIOS setup page. The detail information is added in [PATCH 5/6].

CryptoPkg:SmmCryptLib: Add real Pkcs5Pbkdf2.c.
SecurityPkg/dec: Add PcdPasswordCleared.
SecurityPkg/include: Add PlatformPasswordLib lib class.

UEFI Capsule-Update and Recovery

~ hucktech ~ Leave a comment

On the EDK2-Devel mailing list, Michael Kinney of Intel has started a new EDK2 wiki page on UEFI Capsule-Based-Firmware Update/Recovery. Capsule Updates are how UEFI-based firmware updates itself.

Draft of documentation for Signed Capsule Feature:
I have started a draft of Wiki pages that describe how to use and verify the Signed Capsule feature from Jiewen Yao. I have focused this first draft on the system firmware update use case for signed capsules. Please review this content and provide feedback. I will work on the remaining 3 signed capsule use cases while the content for this fist use case is reviewed. I plan to add this content to the edk2 Wiki once the reviews are completed.

New UEFI patch that Enables SMM page level protection.

~ hucktech ~ Leave a comment

Jiewen Yao of Intel submitted a 6-part patch to Tianocore which adds SMM security. It appears it is the first version of the patch.

This series patch enables SMM page level protection. Features are:
1) PiSmmCore reports SMM PE image code/data information in EdkiiPiSmmMemoryAttributeTable, if the SMM image is page aligned.
2) PiSmmCpu consumes EdkiiPiSmmMemoryAttributeTable and set XD for data page and RO for code page.
3) PiSmmCpu enables Static Paging for X64 according to PcdCpuSmmStaticPageTable. If it is true, 1G paging for above 4G is used as long as it is supported.
4) PiSmmCpu sets importance data structure to be read only, such as Gdt, Idt, SmmEntrypoint, and PageTable itself.

tested platform:
1) Intel internal platform (X64).
2) EDKII Quark IA32
3) EDKII Vlv2  X64
4) EDKII OVMF IA32 and IA32X64.

  MdeModulePkg/Include: Add PiSmmMemoryAttributesTable.h
  MdeModulePkg/dec: Add gEdkiiPiSmmMemoryAttributesTableGuid.
  MdeModulePkg/PiSmmCore: Add MemoryAttributes support.
  UefiCpuPkg/dec: Add PcdCpuSmmStaticPageTable.
  UefiCpuPkg/PiSmmCpuDxeSmm: Add paging protection.
  QuarkPlatformPkg/dsc: enable Smm paging protection.

New UEFI Capsule Update and Recovery sample

~ hucktech ~ Leave a comment

Jiewen Yao of Intel checked in a *45-part* patch to the Tianocore project, adding a new UEFi Capsule sample and documentation!

This series patch provides sample on how to do signed capsule update and recovery in EDKII. The feature includes:
1) Define EDKII signed system BIOS capsule format.
2) Provide EDKII signed system BIOS update sample.
3) Provide EDKII signed recovery sample.
4) Provide Microcode update sample for X86 system.
5) Update Quark to use new capsule/recovery solution.
6) Update Vlv2(MinnowMax) to use new capsule/recovery solution.

The signed capsule/recovery solution is in MdeModulePkg. The capsule in IntelFrameworkModulePkg is deprecated. The Microcode update solution is in UefiCpuPkg.

A Tour Beyond BIOS Implementing Profiling in EDK II
Jiewen Yao, Vincent Zimmer, Star Zeng, Fan Jeff
The Unified Extensible Firmware Interface (UEFI) and Platform Initialization (PI) specification defines rich execution environments such as Security (SEC), Pre-EFI Initialization (PEI), Driver Execution Environment (DXE), System Management Mode (SMM) and UEFI Runtime (RT) for firmware drivers. There are more and more features added into a firmware. At same time, the firmware still has a resource constrained environment. In addition to functionality, the size, performance, and security are three major concerns of a firmware engineer. This paper introduces several profiling features implemented in EDK II to help the UEFI firmware developer to analyze the size, performance and security of a UEFI firmware implementation.

Getting Started with UEFI HTTP over TLS (HTTPS) Boot on EDK II
Wu Jiaxin
HTTP over TLS (HTTPS) boot is a standard implementation for securely booting using the Unified Extensible Firmware Interface (UEFI) over a network device. HTTPS Boot is especially important for clients using potentially insecure networks outside of corporate infrastructure. Security for UEFI HTTPS Boot is provided by the underlying Transport Layer Security (TLS).
This document assumes that the reader is familiar with the EDK II HTTP Boot Getting Started Guide.

Intel FSP 2.0

~ hucktech ~ 1 Comment

Jiewen Yao of Intel submitted a 19-part patch to the UEFI Forum’s EDK2 project today, adding Intel FSP 2.0 support.

(The comments for the patch are also the first time I’ve seen a pointer to the 2.0 FSP spec. Strangely, at the moment Intel.com is down for me, though the rest of the intarwebs appears to be up, so I cannot verify the FSP PDF URL…)

This series of patch is to support FSP2.0 specification at
https://firmware.intel.com/sites/default/files/FSP_EAS_v2.0_Draft%20External.pdf

Some major updates include:
1) One FSP binary is separated to multiple components:
FSP-T, FSP-M, FSP-S, and optional FSP-O.
Each component has its own configuration data region.
2) All FSP-APIs use same UPD format – FSP_UPD_HEADER.
3) Add EnumInitPhaseEndOfFirmware notifyphase.
4) FSP1.1/FSP1.0 compatibility is NOT maintained.

The new Intel platform will follow FSP2.0.
The old platform can either use an old EDK branch, or move FSP1.1 support to platform directory.

We also add rename Fsp* to FspWrapper* in IntelFspWrapperPkg, to indicate that it is for FspWrapper only.

  IntelFspPkg: Update FSP header file to follow FSP2.0 spec.
  IntelFspPkg: Update FSP private header file used by FSP2.0 implementation.
  IntelFspPkg-FspCommonLib: Update FSP common lib for FSP2.0.
  IntelFspPkg/FspPlatformLib: Update FSP platform lib for FSP2.0.
  IntelFspPkg/FspSecPlatformLib: Update FSP SecPlatform lib for FSP2.0.
  IntelFspPkg/FspSecCore: Update FSP SecCore for FSP2.0.
  IntelFspPkg/FspNotifyPhase: Separate FSP NotifyPhase from DxeIpl to new module.
  IntelFspPkg: Update DEC/DSC for FSP2.0.
  IntelFspPkg/Tool: Update FSP tool for FSP2.0.
  IntelFspWrapperPkg/Ppi: Update FspInitDone to FspSiliconInitDone.
  IntelFspWrapperPkg/FspWrapperApiLib: Update FspApiLib to FspWrapperApiLib.
  IntelFspWrapperPkg/FspWrapperApiTestLib: Add ApiTestLib as hook.
  IntelFspWrapperPkg/FspWrapperHobProcessLib: Update FspHobProcessLib to FspWrapperHobProcessLib.
  IntelFspWrapperPkg/FspWrapperPlatformLib: Update FspPlatformInfoLib to FspWrapperPlatformLib.
  IntelFspWrapperPkg/FspWrapperPlatformSecLib: Align PlatformSecLib defined in UefiCpuPkg.
  IntelFspWrapperPkg/FspWrapperSecCore: Remove FspWrapperSecCore.
  IntelFspWrapperPkg/FspInit: Split FspInitPei to FspmWrapperPeim and FspsWrapperPeim.
  IntelFspWrapperPkg/FspWrapperNotifyDxe: Update FspNotifyDxe to FspWrapperNotifyDxe.
  IntelFspWrapperPkg: Update DEC/DSC for FSP2.0.
