ShellPkg/AcpiView: Update print-formatter prototype

2024-08-01T17:20:10+00:00

As of now, the print-formatter implemented by the FNPTR_PRINT_FORMATTER function pointer takes two parameters, the format string and the pointer to the field. For cases where the print-formatter has to have access to the length of the field, there is no clean way to currently do it. In order to resolve this, update the print-formatter's prototype to take the length of the field as a third parameter. This change should improve the overall robustness and flexibility of AcpiView.

ShellPkg/AcpiView: Update field-validator prototype

2024-08-01T17:20:10+00:00

As of now, the field-validator implemented by FNPTR_FIELD_VALIDATOR function pointer takes two parameters, the pointer to the field and a context pointer. For cases where the validator has to have access to the length of the field, there is no clean way to currently do it. In order to resolve this, this commit updates the field-validator's prototype to take the length of the field as an additional parameter. This enhancement allows field validators to perform more comprehensive validation, especially when the length of the field is critical to the validation logic. This change should improve the overall robustness and flexibility of AcpiView.

ShellPkg/AcpiView: Refactor configuration

2020-06-30T01:39:50+00:00

A new file and header (AcpiViewConfig.[ch]) is created that houses the user configuration. This declutters the core code and improves modularity of the design. The module level symbols for verbosity, table selection, and highlighting are refactored into the new file. Cc: Ray Ni Cc: Zhichao Gao Reviewed-by: Zhichao Gao Signed-off-by: Tomas Pilar

ShellPkg: acpiview: Prevent infinite loop if structure length is 0

2020-02-20T09:27:00+00:00

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. Signed-off-by: Krzysztof Koch Reviewed-by: Sami Mujawar Reviewed-by: Zhichao Gao

ShellPkg: acpiview: SRAT: Prevent buffer overruns

2019-08-12T17:14:07+00:00

Modify the SRAT parsing logic to prevent reading past the table buffer length provided. Check if the Static Resource Allocation Structure's buffer fits in the SRAT table buffer before its contents are dumped. Prevent buffer overruns when reading the Static Resource Allocation Structure's header.
