ShellPkg: Fix incorrect PPTT FlagName dereference

2022-02-07T01:52:17+00:00

Bugzilla: 3770 (https://bugzilla.tianocore.org/show_bug.cgi?id=3770) The PPTT parser in AcpiView incorrectly dereferences a pointer to FlagName when trying to log an error with the PPTT cache flags, which can lead to random crashes and other errors. Also fix some spacing in the error message to ensure the message is printed cleanly. Signed-off-by: Chris Jones Reviewed-by: Rebecca Cran Reviewed-by: Sami Mujawar

ShellPkg: Add Cache ID to PPTT parser

2021-12-10T20:06:52+00:00

Bugzilla: 3697 (https://bugzilla.tianocore.org/show_bug.cgi?id=3697) Update the Acpiview PPTT parser with the Cache ID field and relevant validations as defined in tables 5.140 and 5.141 of the ACPI 6.4 specification. Signed-off-by: Chris Jones Reviewed-by: Zhichao Gao Reviewed-by: Sami Mujawar

ShellPkg: Update Acpiview PPTT parser to ACPI 6.4

2021-12-10T20:06:52+00:00

Bugzilla: 3697 (https://bugzilla.tianocore.org/show_bug.cgi?id=3697) Update the Acpiview PPTT parser to use Acpi64.h. As part of the changes, remove support for parsing PPTT type 2 ID structure.

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: PPTT: Validate global pointers before use

Check if the NumberOfPrivateResources, ProcessorTopologyStructureType and ProcessorTopologyStructureLength pointers have been successfully updated before they are used for further table parsing. Signed-off-by: Krzysztof Koch

ShellPkg: acpiview: PPTT: Prevent buffer overruns

2019-08-12T17:14:03+00:00

Modify the PPTT table parsing logic to prevent reading past the ACPI buffer lengths provided. Check if the Number of Private Resources specified in the Processor Hierarchy Node (Type 0) is possible given the Type 0 Structure's buffer length. Make sure that the processor topology structure's buffer fits in the PPTT table buffer before its contents are dumped. Prevent buffer overruns when reading the processor topology structure's header.
