* MdePkg: Define AARCH64_CPTR_RES1 and AARCH64_CPTR_DEFAULTJessica Clarke7 days1-1/+3
| | | | | | | | | | These constants give the set of RES1 bits in CPTR_EL2, as 1s, and the default value to use for CPTR_EL2 in order to enable all known (or harmless) features but no unknown ones that require EL2 knowledge. This will be used by ArmPlatformPkg in the following commit, separated due to being different packages, even though the combined change is tiny. Signed-off-by: Jessica Clarke <jrtc27@jrtc27.com>
* ArmPlatformPkg,MdePkg: Rename AARCH64 CPACR_CP_FULL_ACCESSJessica Clarke7 days1-4/+4
| | | | | | | | | | | | | | CP_FULL_ACCESS is a misnomer, we only enable access to SIMD/FP state, and although the register's mnemonic is CPACR_EL1, its full name is "Architectural Feature Access Control Register", with AArch64 having no coprocessors like AArch32 did, so the "CP" is also not appropriate. Rename it to show it's the default value we use on entry, and define it in terms of the existing CPACR_FPEN_FULL rather than a magic constant with the same value to more clearly document that fact. Also update comments to reflect all this (including the CPTR_EL2 case). Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Jessica Clarke <jrtc27@jrtc27.com>
* MdePkg: MdeLibs.dsc.inc: Apply StackCheckLibNull to All Module TypesOliver Smith-Denny8 days1-13/+8
| | | | | | | | | | | | | | | Now that the ResetVectors are USER_DEFINED modules, they will not be linked against StackCheckLibNull, which were the only modules causing issues. So, we can now remove the kludge we had before and the requirement for every DSC to include StackCheckLibNull for SEC modules and just apply StackCheckLibNull globally. This also changes every DSC to drop the SEC definition of StackCheckLibNull.

* MdePkg: Fix null macros for XCODE5 and CLANGMike Beaton2024-10-181-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building OvmfPkg in RELEASE mode in the XCODE5 toolchain, the ASSERT_EFI_ERROR change prevents this error: .../MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c:141:15: error: variable 'Status' set but not used [-Werror,-Wunused-but-set-variable] EFI_STATUS Status; ^ which is currently stopping the build. When building in RELEASE mode in the CLANGPDB toolchain,the DEBUG macro change prevents this error: .../edk2/OvmfPkg/VirtioSerialDxe/VirtioSerial.c:28:22: error: variable &apos;EventNames&apos; is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] STATIC CONST CHAR8 *EventNames[] = { ^ which is currently stopping the build. CLANGDWARF produces the same error as CLANGPDB above, if -Wno-unneeded-internal-declaration is removed from its build flags. With the null DEBUG macro change, this warning suppression can be removed from CLANGDWARF, which is considered a benefit as it has the potential to catch real coding errors. This is done in a subsequent commit. This commit has the desirable side effect that we no longer require (and cannot use) explicit `#ifndef MDEPKG_NDEBUG` around items only used in DEBUG macros. This requires the ArmPkg change made here to be in the same commit as the MdePkg changes. Note: In common with existing macros in EDK II, including the pre-existing and unchanged DEBUG/NOOPT versions of the macros which are modified here, we use the standard approach of adding `do { ... } while (FALSE)` wrapping to ensure that the macros behave correctly with surrounding code (e.g. require a following ';' and do not combine in unexpected ways with nearby conditionals).

* 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: 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.

* 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.

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>
