2023-04-10MdeModulePkg: Update code to be more C11 compliant by using __func__Rebecca Cran1-1/+1
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout MdeModulePkg.

2023-02-15MdeModulePkg/Library: PcdAcpiS3Enable set FALSE cause Assertlijun10x1-24/+108
Some platforms don't support S3 with PcdAcpiS3Enable set as False. Debug mode bios will ASSERT at this time as Follows. ASSERT_RETURN_ERROR (Status = Out of Resources) DXE_ASSERT!: Edk2\MdePkg\Library\BaseS3PciSegmentLib\S3PciSegmentLib.c (61): !(((INTN)(RETURN_STATUS)(Status)) < 0) Steps to reproduce the issue: 1.Set PcdAcpiS3Enable to FALSE. 2.Build the bios in debug mode. 3.Power on and Check the serial log. Note: Prerequisite is that S3PciSegmentLib is Called and the caller's code is run. Root Cause: S3PciSegmentLib call S3BootScriptLib controlled by PcdAcpiS3Enable. If PcdAcpiS3Enable set as false, S3BootScriptLib will return error status(Out of Resources). S3PciSegmentLib will ASSERT if S3BootScriptLib return error. Solution: Make S3BootScriptLib return success if PcdAcpiS3Enable was disabled, which behave as a null S3BootScriptLib instance which just return success for no action is required to do.

2017-03-06MdeModulePkg: Refine casting expression result to bigger sizeHao Wu1-2/+2
There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

2017-03-06MdeModulePkg: Refine type cast for pointer subtractionHao Wu1-2/+2
For pointer subtraction, the result is of type "ptrdiff_t". According to the C11 standard (Committee Draft - April 12, 2011): "When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. The size of the result is implementation-defined, and its type (a signed integer type) is ptrdiff_t defined in the <stddef.h> header. If the result is not representable in an object of that type, the behavior is undefined." In our codes, there are cases that the pointer subtraction is not performed by pointers to elements of the same array object. This might lead to potential issues, since the behavior is undefined according to C11 standard. Also, since the size of type "ptrdiff_t" is implementation-defined. Some static code checkers may warn that the pointer subtraction might underflow first and then being cast to a bigger size. For example: UINT8 *Ptr1, *Ptr2; UINTN PtrDiff; ... PtrDiff = (UINTN) (Ptr1 - Ptr2); The commit will refine the pointer subtraction expressions by casting each pointer to UINTN first and then perform the subtraction: PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2; Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Hao Wu <hao.a.wu@intel.com> Acked-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Feng Tian <feng.tian@intel.com>
2017-01-03MdePkg, MdeModulePkg: S3BootScriptSaveMemPoll(): accept 64-bit LoopTimesLaszlo Ersek1-1/+1
The BaseNull instance of S3BootScriptLib obviously doesn't care about the type of the S3BootScriptSaveMemPoll() function's LoopTimes parameter; this lib instance doesn't do anything with the parameters received in S3BootScriptSaveMemPoll(). The PiDxe instance saves the LoopTimes parameter in EFI_BOOT_SCRIPT_MEM_POLL.LoopTimes. This target field already has UINT64 type. Furthermore, the BootScriptExecuteMemPoll() function in the same library instance already uses a local UINT64 variable called LoopTimes to count up to EFI_BOOT_SCRIPT_MEM_POLL.LoopTimes. This means that the the UINTN type for S3BootScriptSaveMemPoll()'s LoopTimes parameter is an unnecessary restriction. The callers of S3BootScriptSaveMemPoll() will be updated in the next patches, functionally. At this stage, they will continue to compile, since UINT64 parameters can accept UINTN arguments.

PiDxeS3BootScriptLib has a constructor S3BootScriptLibInitialize() that registers ready-to-lock callback S3BootScriptSmmEventCallBack() and several more. The library is linked to SMM modules. If the module entry-point function returns error (because of lack of resources, unsupported, whatever), the module will be unloaded and the notify callback pointers will point to undefined memory. On ready-to-lock exception occurs when calling S3BootScriptSmmEventCallBack(), and probably all the other callbacks registered by the constructor would also cause exception. This patch is to implement library Destructor to free the resources allocated by S3BootScriptLibInitialize() and unregister callbacks.

2016-04-28MdeModulePkg: PiDxeS3BootScriptLib: honor PcdAcpiS3EnableLaszlo Ersek1-0/+4
In the edk2 tree, there are currently four drivers that consume PcdAcpiS3Enable: IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe/AcpiS3SaveDxe.inf MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf MdeModulePkg/Universal/Acpi/SmmS3SaveState/SmmS3SaveState.inf From these, AcpiS3SaveDxe is the only one that isn't also a client of the S3BootScriptLib class; all the others (BootScriptExecutorDxe, S3SaveStateDxe, SmmS3SaveState) are clients of the S3BootScriptLib class. In turn, the edk2 tree contains only one non-Null instance of the S3BootScriptLib class: MdeModulePkg/Library/PiDxeS3BootScriptLib/DxeS3BootScriptLib.inf Therefore we can safely state that BootScriptExecutorDxe, S3SaveStateDxe, and SmmS3SaveState are all linked against PiDxeS3BootScriptLib. Now, if PcdAcpiS3Enable is FALSE when either of BootScriptExecutorDxe, SmmS3SaveState, or SmmS3SaveState is dispatched, then the following happens: - The constructor of PiDxeS3BootScriptLib, function S3BootScriptLibInitialize(), registers a protocol installation callback for gEfiDxeSmmReadyToLockProtocolGuid. Namely, the function S3BootScriptEventCallBack(). - The driver immediately exits with EFI_UNSUPPORTED from its entry point function, upon seeing PcdAcpiS3Enable == FALSE. (See commits 800c02fbe2da6, 125e093876414, and d2d38610603f6.) - This leaves a dangling callback pointer in the DXE core. - When Platform BDS installs gEfiDxeSmmReadyToLockProtocolGuid (which is a valid thing to do for locking down SMM, even in the absence of S3 support!), things blow up. Fix this issue by returning immediately from S3BootScriptLibInitialize() if PcdAcpiS3Enable is FALSE -- it is useless to initialize the library instance if the containing driver module exits first thing in its entry point.

Normally, DynamicDefault PCD set is expected to be success, but DynamicHii PCD set failure is a legal case. For this case, PcdS3BootScriptTablePrivateDataPtr and PcdS3BootScriptTablePrivateSmmDataPtr are expected to be DynamicDefault, so use PcdSet64S to instead of PcdSet64 and assert when set failure.

2015-09-15MdeModulePkg PiDxeS3BootScriptLib: Remove a hidden assumption.Star Zeng1-150/+327
What to do: 1. Remove a hidden assumption "No SMM driver writes BootScript between SmmReadyToLock and S3SleepEntryCallback". 1.1. Use SmmExitBootServices and SmmLegacyBoot notification to record AtRuntime flag. 1.2. Use mBootScriptDataBootTimeGuid LockBox to save boot time boot script data to handle potential INSERT boot script at runtime in SMM. 2. Do not depend on OS to help restore ACPINvs data and use EfiReservedMemoryType instead of EfiACPIMemoryNVS. 2.1. Use mBootScriptSmmPrivateDataGuid LockBox to save boot script SMM private data with BackFromS3 = TRUE at runtime. S3 resume will help restore it to tell the Library the system is back from S3. Why to do: 1. The hidden assumption "No SMM driver writes BootScript between SmmReadyToLock and S3SleepEntryCallback" will cause confusion to the library's consumer and block the usage of "SMM driver writes BootScript after SmmReadyToLock". So Remove the assumption. 2. In original code, there might be a corner case that malicious code patch ACPINvs boot TableLength field same as SMM boot script. So that it can skip the table restore. The impact is that BootScript in SMM may be overridden by malicious code. -------------------- CopyMem ((VOID*)&TableHeader, (VOID*)mS3BootScriptTablePtr->TableBase, sizeof(EFI_BOOT_SCRIPT_TABLE_HEADER)); if (mS3BootScriptTablePtr->TableLength + sizeof(EFI_BOOT_SCRIPT_TERMINATE) != TableHeader.TableLength) { // TableLength is in NVS ...... // // NOTE: We should NOT use TableHeader.TableLength, because it is already updated to be whole length. // mS3BootScriptTablePtr->TableLength = (UINT32)(mLockBoxLength - sizeof(EFI_BOOT_SCRIPT_TERMINATE)); ? This line can be skipped. -------------------- So use EfiReservedMemoryType instead of EfiACPIMemoryNVS as the code has been updated to not depend on OS to help restore ACPINvs data.
