  • [202405] ImageValidation.py: Don't parse entire image @Javagedes (#1127)
    Change Details
      ## Description

    This commit modifies the PE parsing functionality to only parse the headers of the image, rather than the entire image. This change is made to improve performance and also the probability of failing to parse the entire image. This comes after this commit (erocarrera/pefile#365) in pefile resulted in efi image parsing failures, breaking the build.

    This commit also wraps the parsing of the image in a try-except block to catch any exceptions that may be raised during parsing, to cleanly exit.

    See: microsoft/mu_tiano_platforms#1025 and erocarrera/pefile#421

  • [202405] ImageValidation: Determine profile from inf MODULE\_TYPE @Javagedes (#1124)
    Change Details
      ## Description

    In previous iterations, the profile was determined by parsing the makefile, looking for MODULE_TYPE. As each OS / tool chain may use a different makefile type, this was not a reliable method. This updates the plugin to read the INF for the compiled efi file to determine the MODULE_TYPE and thus the profile.

    Change Details
      ## Description

    In addition to what was said in the Cherry-Pick in #1096.

    It looks like Edk2 picked up these changes, reverted them, and then added them back because Ovmf packages had already started consuming them.

    The changes should not impact existing platforms, because the changes only modify PiSmmCpuDxeSmm.

  • [Cherry-Pick] UefiCpuPkg: Add PcdCpuSmmApSyncTimeout2 PCD @apop5 (#1096)
    Change Details
      ## Description Cherry-Picking PCD definition from edk2. This does not change the basecore functionality to consume this pcd.

    Provide the capability for platform to specifies the 2nd timeout value in microseconds for the BSP/AP in SMM to wait for one another to enter SMM.

    The added interface can enhance the flexibility of timeout configuration. In some cases, certain processors may not be able to enter SMI, and prolonged waiting could lead to kernel soft/hard lockup. We have now defined two timeouts. The first timeout can be set to a smaller value to reduce the waiting period. Processors that are unable to enter SMI will be woken up through SMIIPL to enter SMI, followed by a second waiting period. The second timeout can be set to a larger value to prevent delays in processors entering SMI case due to the long instruction execution.

⚠️ Breaking Changes

  • [REBASE\&FF][CHERRY-PICK] ImageValidation: Add default configuration @Javagedes (#1104)
    Change Details
      Previously, ImageValidation was an "opt-in" plugin by setting a build variable `PE_VALIDATION_PATH`, however with this pull request, Image Validation will be on by default, with some default configuration that can be changed with a custom configuration yaml file.

    The default requirements are:

    1. All efi binaries must not be both write and execute
    2. All efi binaries must have an image base of 0x0
    3. All dxe phase binaries must be 4k section aligned, with the one exception of AARCH64 DXE_RUNTIME_DRIVERS, which must be 64k aligned.

    compiled binaries that need to be opted out of, can do so by adding an IGNORE_LIST in the configuration file

    {
      "IGNORE_LIST": ["Shell.efi", "etc"]
    }

    A cherry-pick of #1100 into release/202311

    • Impacts functionality?
    • Impacts security?
    • Breaking change?
    • Includes tests?
    • Includes documentation?

    How This Was Tested

    Confirmed successful execution of the plugin on Windows with QemuQ35 and Ubuntu with QemuSbsa

    Integration Instructions

    Platforms that begin to fail this test will need to generate a configuration yaml file, and set a stuart build variable, PE_VALIDATION_PATH to it. It is suggested to do this in the Platform's PlatformBuild.py.

    The Correct Integration is to evaluate the binary and why it is not meeting the requirements. The platform can elect to update the compilation of the binary to meet the requirements, add or override validation rules for certain MODULE_TYPEs, or simply add the binary to the ignore list. Please review the Plugin's readme.md file for more details on doing any of these things.




  • BaseTools/build\_rule.template: Set additional Rust module linker flags @makubacki (#1098)
    Change Details
      ## Description

    This change sets the ImageBase in the PE header for Rust modules to 0 so they do not have a preferred base. This is similar to the EFI images produced by the edk2 build system. The subsystem type is also set to efi_boot_service_driver instead of the default target specification value of EFI_APPLICATION. Details for changing the subsystem type are here:

    https://doc.rust-lang.org/nightly/rustc/platform-support/unknown-uefi.html#requirements

    Ideally, these values would be set as individual target.<triple>.rustflags in .cargo/config.toml. However, we override the /MAP argument using -C linker-args in build_rule.txt to the build output directory. This must be set dynamically since the output directory and module name are based on per module values.

    Since the cargo configuration file does not support reading environment variables and setting an environment there in a [env] section would be too late to impact the commands that run in build_rules.txt (cargo is called from cargo make based on those rules), this is the simplest approach to retain the map file path in addition to the new changes.

    In the future, this may be moved to a common target specification so the values are available without these changes.

    The BaseCryptLibUnitTestApp tests the linked BaseCryptLib instance's crypto to make sure all functions are performing as expected. With the move to the Crypto binary and the BaseCryptLibOnProtocol instances we disable certain crypto functionality on purpose which causes the test to fail (and also the BaseCryptLibOnProtocol lib to assert). The changes made here use the already existing crypto PCDs to check if the tested cryptography is enabled with the current Crypto binary and if not to skip the test. This will allow the test to show if the enabled crypto is working correctly instead of failing for crypto we don't care about.

    How This Was Tested

    Tested on Qemu and intel physical platforms with various crypto binary layouts. The relevant tests pass and disabled crypto skips their tests. Furthermore when the PCDs are configured to run tests for crypto we don't support with the selected crypto binary, the test fails as expected.

    Integration Instructions

    N/A. Using the crypto binaries should automatically configure the correct PCDs and BaseCryptLib library for the test to work correctly.

🔐 Security Impacting

  • MdeModulePkg: Compatibility Mode: Only Remap System Memory Regions @os-d (#1030)
    Change Details
      ## Description

    When we enter memory protections compatibility mode, we attempt to disable null protection and remap 0 - 0xA0000 as RWX. This was done for x86 systems with broken shim/grubs on Linux that would attempt to use those regions. This resolved that issue and we could boot non-memory protection safe Linux images on x86 HW. However, this approach did not take into account systems that do not have that range marked as system memory, for example ARM64 systems do not have this requirement. As such, this would inappropriately map these regions as RWX when they were not system memory.

    This patch updates the remapping to only remap and disable null protection if these ranges are marked as system memory, otherwise it will leave them alone.

    How This Was Tested

    Tested on an ARM64 platform that does not have 0 - 0xA0000 as system memory, as well as an X86 system that does have that range as system memory, booting a Linux image on both that forces us to enter compatibility mode.

  • BaseTools/Plugin/RustEnvironmentCheck: Use pytools Rust helpers @makubacki (#1037)
    Change Details
      ## Description

    The plugin implementation has moved to edk2-pytool-extensions so it
    can be reused for plugins targeting different scenarios such as
    public/generic (this plugin) or custom internal environments that
    may need to add on additional functionality.

    This simplifies this plugin's implementation significantly.

    How This Was Tested

    • Verified plugin still detects errors properly
    • Unit tests added in edk2-pytool-extensions

    Integration Instructions

    An id has been added to the plugin YAML file (rust-env-check). This
    retains the same scope as before (rust-ci) but allows a custom version
    of the plugin to override this version by specifying:

    • "id_override": "rust-env-check"

    In its YAML file. Otherwise, no integration work is needed.

    There is an example of code that sets id_override (via generated YAML) here for reference.

    edk2-pytool-extenions 0.27.10 is required this change to work due to the new functionality used in that release.

  • [CHERRY-PICK] UefiCpuPkg:fix issue when splitting paging entry @kenlautner (#909)
    Change Details
      ## Description

    This patch is to fix issue when splitting leaf paging entry in CpuPageTableLib code.

    In previous code, before we assign the new child paging structure address to the content of splitted paging entry, PageTableLibSetPnle() is called to make sure the bit7 is set to 0, which indicate the previous leaf entry is changed to non-leaf entry now. There is a gap between we change the bit7 and we assign the new child paging structure address to the content of the splitted paging entry. If the address of code execution or data access happens to be in the range covered by the splitted paging entry, this gap may cause issue.

    In this patch, we prepare the new paging entry content value in a local variable and assign the value to the splitted paging entry at once. The volatile keyword is used to ensure that no optimization will occur in compilation.

  • [CHERRY-PICK] [Release/202311] UnitTestFrameworkPkg: Fix Google Test components with multiple files @Flickdm (#891)
    Change Details
      # Preface

    REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4610

    Google Test hides test registration in global constructors on global objects. Global constructors are traditionally implemented by placing references to the global constructor's symbol in special sections (traditionally named .ctors or .init_array). These sections are not explicitly referenced by the linker, and libc only looks at special start and end symbols (and calls them).

    This works fine if you're linking a program manually using

    gcc a.o b.o c.o -o test_suite
    

    but fails miserably when using static libraries (such as what EDK2 does), because traditional static archive symbol resolution rules don't allow for obj...

What's Changed

  • MuCodeQlQueries.qls: Pin to the 0.9.12 codeq/cpp-queries pack @makubacki (#883)
    Change Details
      ## Description

    The codeql/cpp-queries pack used in MuCodeQlQueries.qls was versioned
    0.9.12 for the CodeQL CLI v2.17.3 release currently used.

    https://github.com/github/codeql/blob/codeql-cli/v2.17.3/cpp/ql/src/qlpack.yml

    This change pins that pack version to prevent the CodeQL CLI and
    pack from getting out of sync until explicitly updated.

    • Impacts functionality?
    • Impacts security?
    • Breaking change?
    • Includes tests?
    • Includes documentation?

    How This Was Tested

    • Verified the CodeQL query pack version listed is pulled.

    Integration Instructions

    • N/A - No change to queries used. Should prevent breaks in the future where
      the latest queries are no longer compatible with the current CodeQL CLI used.


⚠️ Breaking Changes

  • [REVERT] [CHERRY-PICK] Reverts previous commit to update to 2023.2.16, moves to 2023.2.15, corrects extdep, removes duplicate files @Flickdm (#913)
    Change Details
      ## Description

    An incorrect assumption was made that the INF's need to be removed from the CryptoPkgDriver because the MU_BASECORE already had duplicate entries and this aligned with previous releases (Now unlisted 2023.2.16). This goes back to the working release (2023.2.15) and updates the extdep accordingly. Further additional (potentially breaking) changes were required to be made to get the crypto package working. See commit 5efeb20

🚀 Features & ✨ Enhancements

  • [CHERRY-PICK] Add RNG PPI Support [Rebase \& FF] @makubacki (#888)
    Change Details
      ## Description

    MdePkg: Add Random Number Generator (RNG) PPI

    Adds a new PPI that serves the same purpose as EFI_RNG_PROTOCOL in
    DXE. This PPI can be produced by a PEIM to provide a dynamic interface
    to RNG services in PEI.

    This PPI is called EFI_RNG_PPI because it shares the exact same
    interface with EFI_RNG_PROTOCOL which is described in the UEFI
    Speficiation.


    MdePkg: Add PeiRngLib

    Adds a new PEI library instance for RngLib that uses the RNG services
    provided by the RNG PPI.

    This library instance will add a DEPEX on gEfiRngPpiGuid on modules
    it links against. It can be used to allow PEIMs to get RNG support
    over a dynamic interface.


    (cherry picked from mu_basecore/release/202311)

    How This Was Tested

    • MdePkg CI
    • Verify the RNG PPI can be successfully produced and consumed

    Integration Instructions

    If a platform needs to share RNG support across a dynamic interface
    between PEIMs, the RNG PPI can be used. PeiRngLib provides a RngLib
    instance that use the RNG PPI. It will include a dependency on gEfiRngPpiGuid.

  • [CHERRY-PICK] Set EFI\_MEMORY\_SP as System Memory @makubacki (#920)
    Change Details
      ## Description

    Cherry picks 9051d2e from release/202311.

    When supplying DxeCore with a resource descriptor HOB, a platform can choose which memory type to specify. For EFI_MEMORY_SP resource descriptor HOBs, instead of blindly setting GcdReserved as the memory type, respect what the resource descriptor HOB specified. Closes #884.

    Change Details
      # Preface REF: https://github.com//pull/891 - Dropping GOOGLETEST_HOST_UNIT_BUILD option as release/202302 does not have any expectation to support it.

    REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4610

    Google Test hides test registration in global constructors on global objects. Global constructors are traditionally implemented by placing references to the global constructor's symbol in special sections (traditionally named .ctors or .init_array).

    but fails miserably when using static libraries (such as what EDK2 does), because traditional static archive symbol resolution rules don't allow for object files to be pulled in to the link if there isn't an undefined symbol reference to that .o elsewhere.

    Fix it by passing --whole-archive (GCC) and /WHOLEARCHIVE (MSVC). These options force the linker to pull in the entire s...
