* ShellPkg: acpiview: Prevent infinite loop if structure length is 0Krzysztof Koch2020-02-201-7/+8
| | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2534 Extend validation of ACPI structure lengths which are read from the ACPI table being parsed. Additionally check if the structure 'Length' field value is positive. If not, stop parsing the faulting table. Some ACPI tables define internal structures of variable size. The 'Length' field inside the substructure is used to update a pointer used for table traversal. If the byte-length of the structure is equal to 0, acpiview can enter an infinite loop. This condition can occur if, for example, the zero-allocated ACPI table buffer is not fully populated. This is typically a bug on the ACPI table writer side. In short, this method helps acpiview recover gracefully from a zero-valued ACPI structure length.

* ShellPkg: acpiview: DBG2: Prevent buffer overrunsKrzysztof Koch2019-08-121-49/+92
| | | | | | | | | | | | | | | | | | | | | | | | | Modify the DBG2 table parsing logic to prevent reading past the ACPI buffer lengths provided. Modify the signature of the DumpDbgDeviceInfo() function to make it consistent with the ACPI structure processing functions in other acpiview parsers. Now, the length of the Debug Device Information Structure is read before the entire structure is dumped. This refactoring change makes it easier to stop reading beyond the DBG2 table buffer if the Debug Device Information Structure Buffer does not fit in the DBG2 buffer. For processing the first two fields of the Debug Device Information Structure (to get the length) a new ACPI_PARSER array is defined.

* ShellPkg: acpiview: Allow passing buffer length to DumpGasStruct()Krzysztof Koch2019-07-311-1/+1
| | | | | | | | | | | | | | | | | Modify the signature of the DumpGasStruct() function to include the buffer length parameter and to return the number of bytes parsed by the function. This way it becomes possible to prevent buffer overruns when dumping Generic Address Structure's (GAS) fields in the acpiview table parsers. Update all existing DumpGasStruct() calls in acpiview to add the length argument.

* ShellPkg: Add acpiview tool to dump ACPI tablesRuiyu Ni2018-04-231-0/+242
This program is provided to allow examination of ACPI table contents from the UEFI Shell. This can help with investigations, especially at that stage where the tables are not enabling an OS to boot. The program is not exhaustive, and only encapsulates detailed knowledge of a limited number of table types. Default behaviour is to display the content of all tables installed. 'Known' table types will be parsed and displayed with descriptions and field values. Where appropriate a degree of consistency checking is done and errors may be reported in the output. Other table types will be displayed as an array of Hexadecimal bytes. To facilitate debugging, the -s and -d options can be used to generate a binary file image of a table that can be copied elsewhere for investigation using tools such as those provided by acpica.org. This is especially relevant for AML type tables like DSDT and SSDT. The inspiration for this is the existing smbiosview Debug1 Shell command. Many tables are not explicitly handled, in part because no examples are available for our testing. The program is designed to be extended to new tables with minimal effort, and contributions are invited.
