* MdePkg: MdeLibs.dsc.inc: Introduce CUSTOM_STACK_CHECK_LIB MacroOliver Smith-Denny2024-10-041-7/+75
| | | | | | | | | | | | | 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/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-Denny2024-09-134-114/+0
| | | | | | | Now that the new stack check lib implementation is being used everywhere, remove the old one. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
* MdePkg: Create Stack Check LibTaylor Beebe2024-09-1311-0/+463
| | | | | | | | | | | | | | | | | | 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 Beebe2024-09-139-0/+208
| | | | | | | | | | | | | | | | | | | | | 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: Move CompilerIntrinsicsLib from ArmPkgOliver Smith-Denny2024-09-1244-0/+2762
| | | | | | | | | | | | | | | | | | | | 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.

* MdePkg: Fix a buffer overread.John Baldwin2024-09-031-1/+2
| | | | | | | | | | | | | | DevPathToTextUsbWWID allocates a separate copy of the SerialNumber string to append a null terminator if the original string is not null terminated. However, by using AllocateCopyPool, it tries to copy 'Length + 1' words from the existing string containing 'Length' characters into the target string.

* MdePkg/BaseLib: Let CpuDeadLoop() be breakable in debuggerRay Ni2024-06-121-2/+4
| | | | | | | | | | | | | | | | | | | Starting from certain version of Visual Studio C compiler (I don’t have the exact version. I am using VS2019), CpuDeadLoop is optimized quite well by compiler. The compiler does not generate instructions that jump out of the loop when the "Index" is non-zero. It becomes harder/impossible for developers to break out of the dead-loop in debugger. The new version of CpuDeadLoop() compares a volatile global to a volatile local. This forces 2 reads and a comparison on every loop iteration. The local variable can be set to 1 to exit the loop without modifying the global variable. Using VS2019 with max opt enabled, The dead-loop can be exit by setting Index to 1 in a debugger.

| | | | | | | | | | | | | | | | | | | | | | BaseRngLib on AARCH64 will discover whether or not RNDR instructions are supported, by inspecting the ISAR0 identification register, and setting a global boolean accordingly. This boolean is used in subsequent execution to decide whether or not to issue the instruction. The same discovery code also ASSERT()s that RNDR instructions are implemented, which is unnecessary, and breaks execution on systems that incorporate the library but don't implement the instruction (or fail to expose it to the exception level that the firmware executes at). So drop the ASSERT().
