* MdePkg: DebugLib: Check Signature in CR in Release BuildsOliver Smith-Denny2024-10-081-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CR macro is used to access an enclosing structure from a pointer within the structure. In DEBUG builds (i.e. when MDEPKG_NDEBUG is not set and debug asserts are enabled), this macro does signature validation checking to ensure that the structure that has been found is the correct structure, based on a signature passed in by the caller. However, if MDEPKG_NDEBUG is set or debug asserts are disabled, no signature validation is performed, meaning that CR may return an invalid structure that the caller believes is valid and has had signature validation on, causing undefined behavior (memory corruption). We should where at all possible have defined behavior, particularly in RELEASE builds, which are what typical platforms will ship to consumers. This patch updates CR to do the signature validation in all scenarios to provide defined behavior from the macro. In the event of a signature failure, CR will either 1) assert if !MDEPKG_NDEBUG and debug asserts are enabled (existing behavior) or 2) return NULL to indicate to the caller that signature validation failed. There exist consumers today who already, erroneously, rely on this behavior. Another macro, BASE_CR, exists for callers who do not wish to perform signature validation. Any code that wishes to avoid the signature validation should move to this macro. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>

* MdePkg: MdeLibs.dsc.inc: Introduce CUSTOM_STACK_CHECK_LIB MacroOliver Smith-Denny2024-10-042-8/+83
| | | | | | | | | | | | | In order to support a platform overriding StackCheckLibNull provided by MdeLibs.dsc.inc, the CUSTOM_STACK_CHECK_LIB macro is introduced. If this macro is defined, MdeLibs.dsc.inc will not link StackCheckLibNull and it is expected that the platform will link the version(s) of StackCheckLib that it requires. The StackCheckLib README is also updated in this patch to document the new macro and provide additional information. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>

* MdePkg: Fix DEBUG_CODE and PERF_CODE macros for XCODE5Mike Beaton2024-09-272-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | Without these changes, we get the error: error: variable '__DebugCodeLocal' set but not used from the DebugLib.h DEBUG_CODE_BEGIN()/END() macros on XCODE5. Similarly, in NOOPT builds only, we get: error: variable '__PerformanceCodeLocal' set but not used from the PerformanceLib.h PERF_CODE_BEGIN()/END() macros on XCODE5. It is important to note that the previous code involving a local variable was intended to ensure correct behaviour of ; following the macros, in particular that ; should be required: - https://github.com/tianocore/edk2/pull/6226#issuecomment-2364087866 - https://github.com/tianocore/edk2/pull/6226#issuecomment-2364619759 This converted version repeats the standard do { ... } while (FALSE) idiom (which is already used in the END macro) to achieve the same affect.

* MdePkg/DxeRngLib: Add gEfiRngAlgorithmArmRndr to the secure algorithmsPierre Gondois2024-09-132-0/+10
| | | | | | | | | | | | DxeRngLib iterates over a list of secure algorithms before trying to use the default algorithm provided by the Rng protocol. Add gEfiRngAlgorithmArmRndr to this list.

* MdePkg: Remove Old Stack Check Lib ImplementationOliver Smith-Denny2024-09-135-115/+0

* MdePkg: Create Stack Check LibTaylor Beebe2024-09-1312-0/+464
| | | | | | | | | | | | | | | | | | StackCheckLib contains the required functionality for initializing the stack cookie value, checking the value, and triggering an interrupt when a mismatch occurs. The stack cookie is a random value placed on the stack between the stack variables and the return address so that continuously writing past the stack variables will cause the stack cookie to be overwritten. Before the function returns, the stack cookie value will be checked and if there is a mismatch then StackCheckLib handles the failure. Because UEFI doesn't use the C runtime libraries provided by MSVC, the stack check code is written in assembly within this library. GCC and Clang compilers have built-in support for stack cookie checking, so this library only handles failures. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
* MdePkg: Create Stack Check Null LibsTaylor Beebe2024-09-1315-1/+252
| | | | | | | | | | | | | | | | | | | | | Add Null libs for Stack Check and Stack Check Failure Hook Lib that allow a platform to opt out of stack checks and the stack check failure hook lib. StackCheckLib allows implementation (or in this case null implementation) of stack checks on binaries. There is a Host Application specific version of this null lib because MSVC host applications must not be linked against our lib (so the file here is a no-op but that doesn't cause the build system to fail the build for not building a file for MSVC) as it links against the MSVC C runtime lib that provides the stack cookie definitions. GCC host applications do not link against such a C runtime lib and must be linked against our version. StackCheckFailureHookLib lets a platform do custom functionality when a stack check failure occurs (such as log it to a platform defined mechanism). The null lib simply returns.

* MdePkg: Add Stack Cookie Interrupt Vector PCDOliver Smith-Denny2024-09-131-0/+3
| | | | | | | | | | | This patch adds a PCD allowing a platform to specify the interrupt vector to trigger on a stack check failure. On x86, this is an offset into the IDT. On ARM/AARCH64, this triggers a software interrupt that can be decoded to indicate this was a stack check failure. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>

* MdePkg: Move CompilerIntrinsicsLib from ArmPkgOliver Smith-Denny2024-09-1246-0/+2773
| | | | | | | | | | | | | | | | | | | | As per the emailed RFC in https://edk2.groups.io/g/devel/topic/rfc_move/107675828, this patch moves CompilerIntrinsicsLib from ArmPkg to MdePkg as this library provides compiler intrinsics, which are industry standard. This aligns with the goal of integrating ArmPkg into existing packages: https://bugzilla.tianocore.org/show_bug.cgi?id=4121. The newly placed CompilerIntrinsicsLib is added to MdeLibs.dsc.inc as every DSC that builds ARM/AARCH64 needs this library added. The old location is removed from every DSC in edk2 in this commit also to not break bisectability with minimal hoop jumping.

| | | | | | | | | | | | | | | | | | | AsmMacroIoLib.h and AsmMacroIoLibV8.h are used by the CompilerIntrinsicsLib, which is moving to MdePkg. These functions provide standard definitions for ARM/AARCH64 assembly code, respectively, and so are moved to the arch directories in MdePkg to avoid MdePkg having a dependency on ArmPkg. Now that the files are in Arm/ and AArch64/ directories, the filenames are changed to AsmMacroLib.h as we can distinguish the architecture from the path. AsmMacroIoLib.inc is unused and so is removed. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
