MdeModulePkg: Report EFI_SW_DXE_BS_PC_BOOT_OPTION_COMPLETE

2026-09-07T07:37:40+00:00

Previously EfiBootManagerBoot reported EFI_SW_DXE_BS_EC_BOOT_OPTION_FAILED when a boot option returned an error, but reported nothing on success. Report the PI 1.10 status code EFI_SW_DXE_BS_PC_BOOT_OPTION_COMPLETE when a boot option loads, executes, and returns success, so status code listeners can tell that a boot option was attempted and that control returned to firmware.

MdeModulePkg: Fix conditionally uninitialized variables

2026-08-05T08:59:15+00:00

https://github.com/github/codeql/blob/codeql-cli-2.7.3/cpp/ql/src/Security/CWE/CWE-457/ConditionallyUninitializedVariable.qhelp Some local variables, when going through a code path, can end up uninitialized (using the value they had at the start of the function). This is generally due to an error path that can occur based on the library instances, or the unchecked error (i.e. a allocation failing). These variables should be initialized with a known value that will result in the function being able to exit gracefully. Signed-off-by: Aaron Pop

MdeModulePkg: Fix missing NULL tests

https://github.com/github/codeql/blob/codeql-cli-2.7.3/cpp/ql/src/Critical/MissingNullTest.qhelp For items which allocate memory, or get a pointer from another structure, it is important to validate that the pointers are not null before they are dereferenced. Signed-off-by: Aaron Pop

MdeModulePkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

MdeModulePkg: UefiBootManagerLib Change default alignment for ramdisk boot.

2025-08-06T00:59:25+00:00

The ramdisk is modelled as an NVDIMM which have a naturally higher alignment than 4K. Operating systems may wish to map NVDIMMs using large pages, so force the allocation alignment to 2MB. This change was tested using HTTP ramdisk boot, targeting a flat windows image. Signed-off-by: Aaron Pop
