ShellPkg: 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

2020-04-01T10:53:03+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2032 'ping' command's receive flow utilizes a single Rx token which it attempts to reuse before recycling the previously received packet. This causes a situation where under ICMP traffic, Ping6OnEchoReplyReceived() function will receive an already recycled packet with EFI_SUCCESS token status and finally dereference invalid pointers from RxData structure.

ShellPkg: stop using EFI_HANDLE in place of EFI_HII_HANDLE

2019-10-09T07:40:10+00:00

The UefiShell*CommandsLib instances have constructor functions that do something like: gHiiHandle = HiiAddPackages (...); ... ShellCommandRegisterCommandName (..., gHiiHandle, ...); and destructor functions that implement the following pattern: HiiRemovePackages (gHiiHandle); The -- semantic, not functional -- problem is that "gHiiHandle" is declared with type EFI_HANDLE, and not EFI_HII_HANDLE, in all of these library instances, even though HiiAddPackages() correctly returns EFI_HII_HANDLE, and HiiRemovePackages() takes EFI_HII_HANDLE. Once we fix the type of "gHiiHandle", it causes sort of a butterfly effect, because it is passed around widely. Track down and update all of those locations. The DynamicCommand lib instances use a similar pattern, so they are affected too. NOTE: in practice, this patch is a no-op, as both EFI_HII_HANDLE and EFI_HANDLE are typedefs to (VOID*). However, we shouldn't use EFI_HANDLE where semantically EFI_HII_HANDLE is passed around.
