2026-02-24SecurityPkg: Replace include guards with #pragma onceMichael Kubacki1-4/+1
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>

2019-07-19SecurityPkg: introduce the SM3 digest algorithmImran Desai1-0/+4
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1781 GITHUB: https://github.com/idesai/edk2/tree/enable_sm3_measured_boot_v6 EDK2 Support for SM3 digest algorithm is needed to enable TPM with SM3 PCR banks. This digest algorithm is part of the China Crypto algorithm suite. This integration has dependency on the openssl_1_1_1b integration into edk2. This patch add SM3 algorithm in the hashinstance library. Delta in v7: 1.

2019-07-04Revert "SecurityPkg: introduce the SM3 digest algorithm"Laszlo Ersek1-1/+0
This reverts commit 06dd5863b66edd9908834371e07fb4e11383c172. The reason is that said commit directly depends on commit 49c1e683c452 ("MdePkg/Protocol/Hash: introduce GUID for SM3", 2019-07-03), and the latter commit is going to be reverted, due to its review process not having followed established edk2 norms.
