2026-02-24MdeModulePkg: Replace include guards with #pragma onceMichael Kubacki10-40/+10
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 <michael.kubacki@microsoft.com>

2020-11-21MdeModulePkg/LzmaCustomDecompressLib: catch 4GB+ uncompressed buffer sizesLaszlo Ersek2-0/+12
The LzmaUefiDecompressGetInfo() function [MdeModulePkg/Library/LzmaCustomDecompressLib/LzmaDecompress.c] currently silently truncates the UINT64 "DecodedSize" property of the compressed blob to the UINT32 "DestinationSize" output parameter. If "DecodedSize" is 0x1_0000_0100, for example, then the subsequent memory allocation (for decompression) will likely succeed (allocating 0x100 bytes only), but then the LzmaUefiDecompress() function (which re-fetches the uncompressed buffer size from the same LZMA header into a "SizeT" variable) will overwrite the buffer. Catch (DecodedSize > MAX_UINT32) in LzmaUefiDecompressGetInfo() at once. This should not be a practical limitation. (The issue cannot be fixed for 32-bit systems without spec modifications anyway, given that the "OutputSize" output parameter of EFI_GUIDED_SECTION_EXTRACTION_PROTOCOL.ExtractSection() has type UINTN, not UINT64.)
