* MdeModulePkg/UefiHiiLib:Fix incorrect comparison expressionDandan Bi2017-04-051-2/+3
| | | | | | | | | | | | | | | | | | Fix the incorrect comparison between pointer and constant zero character. https://bugzilla.tianocore.org/show_bug.cgi?id=416 V2: The pointer StringPtr points to a string returned by ExtractConfig/ExportConfig, if it is NULL, function InternalHiiIfrValueAction will return FALSE. So in current usage model, the StringPtr can not be NULL before using it, so we can add ASSERT here.

* MdeModulePkg/PeiCore: avoid EFI_IMAGE_MACHINE_TYPE_SUPPORTED to check archArd Biesheuvel2017-03-291-3/+5
| | | | | | | | | | | | | | | | | | The EFI_IMAGE_MACHINE_TYPE_SUPPORTED() macro is abused in the PeiCore code to decide whether the system we are compiling for can deal with executable code being copied elsewhere and executed from there. As stated in the comment, this is fundamentally a property of the compiler target, and so this should be made dependent on MDE_CPU_xxx preprocessor defines, and not on whether or not the runtime target can deal with PE/COFF images of a certain machine type. On X86/IA32, this mostly boils down to the same thing, but not on other architectures, so let's clean this up.

* MdeModulePkg/MemoryProtection: split protect and unprotect pathsArd Biesheuvel2017-03-211-50/+35
| | | | | | | | | | | | | | | | | | | Currently, the PE/COFF image memory protection code uses the same code paths for protecting and unprotecting an image. This is strange, since unprotecting an image involves a single call into the CPU arch protocol to clear the permission attributes of the entire range, and there is no need to parse the PE/COFF headers again. So let's store the ImageRecord entries in a linked list, so we can find it again at unprotect time, and simply clear the permissions. Note that this fixes a DEBUG hang on an ASSERT() that occurs when the PE/COFF image fails to load, which causes UnprotectUefiImage() to be invoked before the image is fully loaded.

| | | | | | | | | | | | | | | The BGRT table has an 8 byte field for the memory address of the image data, and yet the driver explicitly allocates below 4 GB. This results in an ASSERT() on systems that do not have any memory below 4 GB to begin with. Since neither the PI, the UEFI or the ACPI spec contain any mention of why this data should reside below 4 GB, replace the allocation call with an ordinary AllocatePages() call.

| | | | | | | | | | | | | | | | | | | Invocations of EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() may result in a crash when the value of PcdAcpiExposedTableVersions does not include EFI_ACPI_TABLE_VERSION_1_0B. The reason is that EFI_ACPI_TABLE_PROTOCOL::InstallAcpiTable() will only populate the Rsdt1/Rsdt3 pointers when EFI_ACPI_TABLE_VERSION_1_0B is set, whereas EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() will invoke PublishTables with EFI_ACPI_TABLE_VERSION_1_0B alawys set, resulting in a NULL pointer dereference of the Rsdt1/Rsdt3 pointers. So take PcdAcpiExposedTableVersions into account for UninstallAcpiTable as well.

* MdeModulePkg/DxeCore: deal with allocations spanning several memmap entriesArd Biesheuvel2017-03-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When attempting to perform page allocations using AllocateAddress, we fail to check whether the entire region is free before splitting the region. This may lead to memory being leaked further into the routine, when it turns out that one of the memory map entries intersected by the region is already occupied. In this case, prior conversions are not rolled back. For instance, starting from this situation 0x000040000000-0x00004007ffff [ConventionalMemory ] 0x000040080000-0x00004009ffff [Boot Data ] 0x0000400a0000-0x000047ffffff [ConventionalMemory ] a failed EfiLoaderData allocation @ 0x40000000 that covers the BootData region will fail, but leave the first part of the allocation converted, so we end up with 0x000040000000-0x00004007ffff [Loader Data ] 0x000040080000-0x00004009ffff [Boot Data ] 0x0000400a0000-0x000047ffffff [ConventionalMemory ] even though the AllocatePages() call returned an error. So let's check beforehand that AllocateAddress allocations are covered by a single memory map entry, so that it either succeeds or fails completely, rather than leaking allocations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACPI specification, up to and including revision 5.1 Errata A, allows the DSDT and X_DSDT fields to be both set in the FADT. (Obviously, this only makes sense if the DSDT address is representable in 4 bytes.) Starting with 5.1 Errata B, specifically for Mantis 1393 <https://mantis.uefi.org/mantis/view.php?id=1393>, the spec requires at most one of DSDT and X_DSDT to be set to a nonzero value. MdeModulePkg/AcpiTableDxe handles this mutual exclusion somewhat inconsistently. - If the caller of EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() installs the tables in "DSDT, FADT" order, then we enforce the exclusion between the DSDT and X_DSDT fields: DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT B] -------------- --------- ----------- yes set clear no clear set This behavior conforms to 5.1 Errata B. (And it's not required by earlier versions of the spec.) - If the caller passes in the tables in "FADT, DSDT" relative order, then we do not enforce the exclusion: DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT A] -------------- --------- ----------- yes set set no clear set This satisfies 5.1 Errata A and earlier, but breaks 5.1 Errata B and later. Unify the handling of both relative orders. In particular, check the major and minor version numbers in the FADT. If the FADT version is strictly before 5.1, then implement [VARIANT A]. If the FADT version is equal to or larger than 5.1, then implement [VARIANT B]. We make three observations: - We can't check the FADT table version precisely against "5.1 Errata B"; erratum levels are not captured in the table. We err in the safe direction, namely we enforce the exclusion for "5.1" and "5.1 Errata A". - The same applies to "6.0" versus "6.0 Errata A". Because we cannot distinguish these two, we consider "6.0" to be "equal to or larger than 5.1", and apply [VARIANT B], enforcing the exclusion. - While a blanket [VARIANT B] would be simpler, there is a significant benefit to [VARIANT A], under the spec versions that permit it: compatibility with a wider range of OSPMs (typically, older ones). For example, Igor reported about a "DELL R430 system with rev4 FADT where DSDT and X_DSDT are pointing to the same address". Michael also reported about several systems that exhibit the same.

| | | | | | | | | | | | | | | | Architectures such as AArch64 may run the OS with 16 KB or 64 KB sized pages, and for this reason, the UEFI spec mandates a minimal allocation granularity of 64 KB for regions that may require different memory attributes at OS runtime. So make PeiCore's implementation of AllocatePages () take this into account as well.

* MdeModulePkg: Refine casting expression result to bigger sizeHao Wu2017-03-0634-118/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.

* MdeModulePkg: Refine type cast for pointer subtractionHao Wu2017-03-0611-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
