2014-04-05OvmfPkg: PlatformPei: protect SEC's GUIDed section handler table thru S3Laszlo Ersek
OVMF's SecMain is unique in the sense that it links against the following two libraries *in combination*: - IntelFrameworkModulePkg/Library/LzmaCustomDecompressLib/ LzmaCustomDecompressLib.inf - MdePkg/Library/BaseExtractGuidedSectionLib/ BaseExtractGuidedSectionLib.inf The ExtractGuidedSectionLib library class allows decompressor modules to register themselves (keyed by GUID) with it, and it allows clients to decompress file sections with a registered decompressor module that matches the section's GUID. BaseExtractGuidedSectionLib is a library instance (of type BASE) for this library class. It has no constructor function. LzmaCustomDecompressLib is a compatible decompressor module (of type BASE). Its section type GUID is gLzmaCustomDecompressGuid == EE4E5898-3914-4259-9D6E-DC7BD79403CF When OVMF's SecMain module starts, the LzmaCustomDecompressLib constructor function is executed, which registers its LZMA decompressor with the above GUID, by calling into BaseExtractGuidedSectionLib: LzmaDecompressLibConstructor() [GuidedSectionExtraction.c] ExtractGuidedSectionRegisterHandlers() [BaseExtractGuidedSectionLib.c] GetExtractGuidedSectionHandlerInfo() PcdGet64 (PcdGuidedExtractHandlerTableAddress) -- NOTE THIS Later, during a normal (non-S3) boot, SecMain utilizes this decompressor to get information about, and to decompress, sections of the OVMF firmware image: SecCoreStartupWithStack() [OvmfPkg/Sec/SecMain.c] SecStartupPhase2() FindAndReportEntryPoints() FindPeiCoreImageBase() DecompressMemFvs() ExtractGuidedSectionGetInfo() [BaseExtractGuidedSectionLib.c] ExtractGuidedSectionDecode() [BaseExtractGuidedSectionLib.c] Notably, only the extraction depends on full-config-boot; the registration of LzmaCustomDecompressLib occurs unconditionally in the SecMain EFI binary, triggered by the library constructor function. This is where the bug happens. BaseExtractGuidedSectionLib maintains the table of GUIDed decompressors (section handlers) at a fixed memory location; selected by PcdGuidedExtractHandlerTableAddress (declared in MdePkg.dec). The default value of this PCD is 0x1000000 (16 MB). This causes SecMain to corrupt guest OS memory during S3, leading to random crashes. Compare the following two memory dumps, the first taken right before suspending, the second taken right after resuming a RHEL-7 guest: crash> rd -8 -p 1000000 0x50 1000000: c0 00 08 00 02 00 00 00 00 00 00 00 00 00 00 00 ................ 1000010: d0 33 0c 00 00 c9 ff ff c0 10 00 01 00 88 ff ff .3.............. 1000020: 0a 6d 57 32 0f 00 00 00 38 00 00 01 00 88 ff ff .mW2....8....... 1000030: 00 00 00 00 00 00 00 00 73 69 67 6e 61 6c 6d 6f ........signalmo 1000040: 64 75 6c 65 2e 73 6f 00 00 00 00 00 00 00 00 00 dule.so......... vs. crash> rd -8 -p 1000000 0x50 1000000: 45 47 53 49 01 00 00 00 20 00 00 01 00 00 00 00 EGSI.... ....... 1000010: 20 01 00 01 00 00 00 00 a0 01 00 01 00 00 00 00 ............... 1000020: 98 58 4e ee 14 39 59 42 9d 6e dc 7b d7 94 03 cf .XN..9YB.n.{.... 1000030: 00 00 00 00 00 00 00 00 73 69 67 6e 61 6c 6d 6f ........signalmo 1000040: 64 75 6c 65 2e 73 6f 00 00 00 00 00 00 00 00 00 dule.so......... The "EGSI" signature corresponds to EXTRACT_HANDLER_INFO_SIGNATURE declared in MdePkg/Library/BaseExtractGuidedSectionLib/BaseExtractGuidedSectionLib.c. Additionally, the gLzmaCustomDecompressGuid (quoted above) is visible at guest-phys offset 0x1000020. Fix the problem as follows: - Carve out 4KB from the 36KB gap that we currently have between PcdOvmfLockBoxStorageBase + PcdOvmfLockBoxStorageSize == 8220 KB and PcdOvmfSecPeiTempRamBase == 8256 KB. - Point PcdGuidedExtractHandlerTableAddress to 8220 KB (0x00807000). - Cover the area with an EfiACPIMemoryNVS type memalloc HOB, if S3 is supported and we're not currently resuming. The 4KB size that we pick is an upper estimate for BaseExtractGuidedSectionLib's internal storage size. The latter is calculated as follows (see GetExtractGuidedSectionHandlerInfo()): sizeof(EXTRACT_GUIDED_SECTION_HANDLER_INFO) + // 32 PcdMaximumGuidedExtractHandler * ( sizeof(GUID) + // 16 sizeof(EXTRACT_GUIDED_SECTION_DECODE_HANDLER) + // 8 sizeof(EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER) // 8 ) OVMF sets PcdMaximumGuidedExtractHandler to 16 decimal (which is the MdePkg default too), yielding 32 + 16 * (16 + 8 + 8) == 544 bytes. Regarding the lifecycle of the new area: (a) when and how it is initialized after first boot of the VM The library linked into SecMain finds that the area lacks the signature. It initializes the signature, plus the rest of the structure. This is independent of S3 support. Consumption of the area is also limited to SEC (but consumption does depend on full-config-boot). (b) how it is protected from memory allocations during DXE It is not, in the general case; and we don't need to. Nothing else links against BaseExtractGuidedSectionLib; it's OK if DXE overwrites the area. (c) how it is protected from the OS When S3 is enabled, we cover it with AcpiNVS in InitializeRamRegions(). When S3 is not supported, the range is not protected. (d) how it is accessed on the S3 resume path Examined by the library linked into SecMain. Registrations update the table in-place (based on GUID matches). (e) how it is accessed on the warm reset path If S3 is enabled, then the OS won't damage the table (due to (c)), hence see (d). If S3 is unsupported, then the OS may or may not overwrite the signature. (It likely will.) This is identical to the pre-patch status.

2014-03-31OvmfPkg: AcpiPlatformDxe: download ACPI tables from QEMULaszlo Ersek
Recent qemu versions compose all ACPI tables on the host side, according to the target hardware configuration, and make the tables available to any guest firmware over fw_cfg. See version compatibility information below. The feature moves the burden of keeping ACPI tables up-to-date from boot firmware to qemu (which is the source of hardware configuration anyway). This patch adds client code for this feature. Benefits of the qemu-provided ACPI tables include PCI hotplug for example. Qemu provides the following three fw_cfg files: - etc/acpi/rsdp - etc/acpi/tables - etc/table-loader "etc/acpi/rsdp" and "etc/acpi/tables" are similar, they are only kept separate because they have different allocation requirements in SeaBIOS. Both of these fw_cfg files contain preformatted ACPI payload. "etc/acpi/rsdp" contains only the RSDP table, while "etc/acpi/tables" contains all other tables, concatenated. The tables in these two fw_cfg files are filled in by qemu, but two kinds of fields are left incomplete in each table: pointers to other tables, and checksums (which depend on the pointers). Qemu initializes each pointer with a relative offset into the fw_cfg file that contains the pointed-to ACPI table. The final pointer values depend on where the fw_cfg files, holding the pointed-to ACPI tables, will be placed in memory by the guest. That is, the pointer fields need to be "relocated" (incremented) by the base addresses of where "/etc/acpi/rsdp" and "/etc/acpi/tables" will be placed in guest memory. This is where the third file, "/etc/table-loader" comes in the picture. It is a linker/loader script that has several command types: One command type instructs the guest to download the other two files. Another command type instructs the guest to increment ("absolutize") a pointer field (having a relative initial value) in the pointing ACPI table, present in some fw_cfg file, with the dynamic base address of the same (or another) fw_cfg file, holding the pointed-to ACPI table. The third command type instructs the guest to compute checksums over ranges and to store them. In edk2, EFI_ACPI_TABLE_PROTOCOL knows about table relationships -- it handles linkage automatically when a table is installed. The protocol takes care of checksumming too. RSDP is installed automatically. Hence we only need to care about the "etc/acpi/tables" fw_cfg file, determining the boundaries of each ACPI table inside it, and installing those tables.

2014-03-31OvmfPkg: AcpiS3SaveDxe: do not load if S3 is unsupported/disabled in qemuLaszlo Ersek
The previous patch ensures that the LockBox is protected during DXE (but the OS can still drop it) if S3 is unsupported or disabled. However, S3 related drivers not only save data in the lockbox, they allocate objects with Reserved and AcpiNVS memory types too, which the OS can't (must not) release. This is a waste when S3 is unsupported or disabled. In OVMF a good "choke point" for these drivers is the entry point of AcpiS3SaveDxe. The messages of the following commits are relevant to the data and control flow: - SVN r15290 (git commit 8f5ca05b) - SVN r15305 (git commit 5a217a06) - SVN r15306 (git commit d4ba06df) Prevent AcpiS3SaveDxe from loading when S3 is unsupported or disabled. This should keep away (most of the) dependent drivers too.

2014-03-31OvmfPkg: PlatformPei: lifecycle fixes for the LockBox areaLaszlo Ersek
If (mBootMode == BOOT_ON_S3_RESUME) -- that is, we are resuming --, then the patch has no observable effect. If (mBootMode != BOOT_ON_S3_RESUME && mS3Supported) -- that is, we are booting or rebooting, and S3 is supported), then the patch has no observable effect either. If (mBootMode != BOOT_ON_S3_RESUME && !mS3Supported) -- that is, we are booting or rebooting, and S3 is unsupported), then the patch effects the following two fixes: - The LockBox storage is reserved from DXE (but not the OS). Drivers in DXE may save data in the LockBox regardless of S3 support, potentially corrupting any overlapping allocations. Make sure there's no overlap. - The LockBox storage is cleared. A LockBox inherited across a non-resume reboot, populated with well-known GUIDs, breaks drivers that want to save entries with those GUIDs.
