New Klocwork Taxonomy for ISO/IEC TS 17961 available

Developed by Emenda, the Klocwork ISO/IEC TS 17961 Taxonomy allows for the checking and reporting of violations to the ISO/IEC TS 17961 coding standard. To request a copy of the taxonomy and instructions on how to install it, click here.

As of writing, the rules covered (full and partial) by the taxonomy are in the table below. Please note this content is subject to change in future.

5.6Calling functions with incorrect arguments [argcomp]
5.10Converting a pointer to integer or integer to pointer [intptrconv]
5.12Copying a FILE object [filecpy]
5.13Declaring the same function or object in incompatible ways [funcdecl]
5.14Dereferencing an out-of-domain pointer [nullref]
5.15Escaping the address of an automatic object [addrescape]

5.34Reallocating or freeing memory that was not dynamically allocated [xfree]
5.35Referencing unintialized memory [uninitref]
5.37Tainted strings are passed to a string copying function [taintstrcpy]
5.38Taking the size of a pointer to determine the size of the pointed-to type [sizeofptr]
5.40Using a tainted value to write to an object using a formatted input or output function [taintformatio]
5.44Using identifiers that are reserved for the implementation [resident]
5.45Using invalid format strings [invfmtstr]

The coverage of the standard may increase with future releases of the tool, as new checkers are added. Emenda also offers checker writing and maintenance as a professional service, if your organisation would benefit from increased coverage of this standard, internal guidelines or other standards not yet supported – please contact us or click here to find out more information.
