* MdeModulePkg/Core/Dxe: limit FwVol encapsulation section recursionLaszlo Ersek2020-11-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DXE Core sets up a protocol notify function in its entry point, for instances of the Firmware Volume Block2 Protocol: DxeMain() [DxeMain/DxeMain.c] FwVolDriverInit() [FwVol/FwVol.c] Assume that a 3rd party UEFI driver or application installs an FVB instance, with crafted contents. The notification function runs: NotifyFwVolBlock() [FwVol/FwVol.c] installing an instance of the Firmware Volume 2 Protocol on the handle. (Alternatively, assume that a 3rd party application calls gDS->ProcessFirmwareVolume(), which may also produce a Firmware Volume 2 Protocol instance.) The EFI_FIRMWARE_VOLUME2_PROTOCOL.ReadSection() member performs "a depth-first, left-to-right search algorithm through all sections found in the specified file" (quoting the PI spec), as follows: FvReadFileSection() [FwVol/FwVolRead.c] GetSection() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() // recursive call FindChildNode() is called recursively for encapsulation sections. Currently this recursion is not limited. Introduce a new PCD (fixed-at-build, or patchable-in-module), and make FindChildNode() track the section nesting depth against that PCD.

* MdeModulePkg: Add new PCD to control the evacuate temporary memory feature ↵Guomin Jiang2020-07-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (CVE-2019-11098) REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1614 The security researcher found that we can get control after NEM disable. The reason is that the flash content reside in NEM at startup and the code will get the content from flash directly after disable NEM. To avoid this vulnerability, the feature will copy the PEIMs from temporary memory to permanent memory and only execute the code in permanent memory. The vulnerability is exist in physical platform and haven't report in virtual platform, so the virtual can disable the feature currently. When enable the PcdMigrateTemporaryRamFirmwareVolumes, always shadow all PEIMs no matter the condition of PcdShadowPeimOnBoot or PcdShadowPeimOnS3Boot.

Current statement says the implementation should unset or disable related features but in fact the related code just do nothing (leave it to AS-IS). That means the result might be disabled, or might be not. It depends on other features or platform policy.

* MdeModulePkg/Variable/RuntimeDxe: introduce PcdMaxVolatileVariableSizeLaszlo Ersek2018-03-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable driver doesn't distinguish "non-volatile non-authenticated" variables from "volatile non-authenticated" variables, when checking individual variable sizes against the permitted maximum. PcdMaxVariableSize covers both kinds. This prevents volatile non-authenticated variables from carrying large data between UEFI drivers, despite having no flash impact. One example is EFI_TLS_CA_CERTIFICATE_VARIABLE, which platforms might want to create as volatile on every boot: the certificate list can be several hundred KB in size. Introduce PcdMaxVolatileVariableSize to represent the limit on individual volatile non-authenticated variables. The default value is zero, which makes Variable/RuntimeDxe fall back to PcdMaxVariableSize (i.e. the current behavior). This is similar to the PcdMaxAuthVariableSize fallback. Whenever the size limit is enforced, consult MaxVolatileVariableSize as the last option, after checking - MaxAuthVariableSize for VARIABLE_ATTRIBUTE_AT_AW, - and MaxVariableSize for EFI_VARIABLE_NON_VOLATILE. EFI_VARIABLE_HARDWARE_ERROR_RECORD is always handled separately; it always takes priority over the three cases listed above. Introduce the GetMaxVariableSize() helper to consider PcdMaxVolatileVariableSize, in addition to GetNonVolatileMaxVariableSize(). GetNonVolatileMaxVariableSize() is currently called at three sites, and two of those need to start using GetMaxVariableSize() instead: - VariableServiceInitialize() [VariableSmm.c]: the SMM comms buffer must accommodate all kinds of variables, - VariableCommonInitialize() [Variable.c]: the preallocated scratch space must also accommodate all kinds of variables, - InitNonVolatileVariableStore() [Variable.c] can continue using GetNonVolatileMaxVariableSize(). Don't modify the ReclaimForOS() function as it is specific to non-volatile variables and should ignore PcdMaxVolatileVariableSize.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | PCD PcdNullPointerDetectionPropertyMask is a bitmask used to control the NULL address detection functionality in code for different phases. If enabled, accessing NULL address in UEFI or SMM code can be caught as a page fault exception. BIT0 - Enable NULL pointer detection for UEFI. BIT1 - Enable NULL pointer detection for SMM. BIT2..6 - Reserved for future uses. BIT7 - Disable NULL pointer detection just after EndOfDxe. This is a workaround for those unsolvable NULL access issues in OptionROM, boot loader, etc. It can also help to avoid unnecessary exception caused by legacy memory (0-4095) access after EndOfDxe, such as Windows 7 boot on Qemu.

But most entries are from MemoryAllocationLib. 2. Records at the start. 3. Records all modules. Enhanced memory profile feature: 1. User can know which line of code calls AllocateXXX() API instead of gBS->Allocate(). 2. User can know which line of code calls a specific API that will call AllocateXXX(). 3. User can know total memory allocated by a specific line of code. 4. User can configure to record single module. 5. User can configure when to enable recording. 6. User can know RVA<->Symbol (Function, Source, Line). For the enhanced memory profile feature, 1. Extend MEMORY_PROFILE_DRIVER_INFO to include PdbString. 2. Extend MEMORY_PROFILE_ALLOC_INFO to include ActionString. 3. Extend MEMORY_PROFILE_ACTION to indicate action in memory allocation lib and user defined action. 4. Extend memory profile protocol to include GetRecordingState/ SetRecordingState/Record. 5. Define SMM memory profile protocol. 6. Extend PcdMemoryProfilePropertyMask to support disable recording at the start. 7. Introduce new PCD PcdMemoryProfileDriverPath to control which drivers need memory profile data.

| | | | | | | | | | | | | | | | | | | | | | | | The S3Ready() functional code in AcpiS3SaveDxe of IntelFrameworkModulePkg is to do ACPI S3 Context save. In fact, that is not really related to Intel framework ACPI S3 protocol. IntelFrameworkModulePkg will be deprecated step by step, so move the functional code to MdeModulePkg and S3SaveStateDxe is a good place. The ACPI global variable related code is leaved as is in IntelFrameworkModulePkg AcpiS3SaveDxe for compatibility. PcdS3BootScriptStackSize is also moved from IntelFrameworkModulePkg. The functional code need to get ACPI FACS table and consume LockBoxLib, so need to be before DxeSmmReadyToLock that will shut down SMM lock box interface, EndOfDxe is a good point (OVMF AcpiS3SaveDxe has the reference implementation).
