CryptoPkg: 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. Does not include updates to OpenSSL generated header files checked into the repo. Those in `CryptoPkg\Library\OpensslLib\OpensslGen\`. 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

Stop using deprecated interfaces is left as exercise for another day. So please don't warn for now so -Werror builds can work.

CryptoPkg/BaseCryptLib: split CryptPkcs7Verify.c on behalf of runtime

2019-01-31T13:25:05+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1493 Pkcs7GetAttachedContent() implementation in current CryptPkcs7Verify.c is actually shared by RuntimeCryptLib.inf, SmmCryptLib.inf and BaseCryptLib.inf, which are not correct since there's no use scenario for runtime and AllocatePool() used in this method can only be called in boot time. This patch fix this issue by splitting file CryptPkcs7Verify.c into 3 parts. CryptPkcs7VerifyCommon.c (shared among Base, SMM, Runtime) CryptPkcs7VerifyBase.c (shared between Base, SMM) CryptPkcs7VerifyRuntime.c (for Runtime only) CryptPkcs7VerifyBase.c will have original implementation of Pkcs7GetAttachedContent() as CryptPkcs7Verify.c. CryptPkcs7VerifyRuntime.c provide a NULL version of Pkcs7GetAttachedContent(). No functionality and interface change is involved in this patch.

CryptoPkg: Fix OpenSSL BN wordsize and OPENSSL_SYS_UEFI handling

2015-10-29T14:17:15+00:00

We were manually setting -DSIXTY_FOUR_BIT_LONG or -DTHIRTY_TWO_BIT on the compiler command line when building OpensslLib itself, but not when building BaseCryptLib. But when building BaseCryptLib, we weren't setting OPENSSL_SYS_UEFI *either*. This meant that *that* build was picking up the definition from , and was thus *different* to the version the library was built with, in some cases. So set OPENSSL_SYS_UEFI consistently in OpensslSupport.h and *also* define either SIXTY_FOUR_BIT or THIRTY_TWO_BIT there too.

CryptoPkg/BaseCryptLib: Use accessor functions for ASN1_OBJECT

2015-10-29T14:16:30+00:00

OpenSSL 1.1 introduces new OBJ_get0_data() and OBJ_length() accessor functions and makes ASN1_OBJECT an opaque type. Unlike the accessors in previous commits which *did* actually exist already but just weren't mandatory, these don't exist in older versions of OpenSSL. So introduce macros which do the right thing, for compatibility.
