Secure Coding Standard¶

The strongSwan project adheres to the following recommendations and rules recommended by the CERT C Secure Coding Standard:

Preprocessor (PRE)¶

Full Adherence¶

• PRE03-C. Prefer typedefs to defines for encoding types

• PRE04-C. Do not reuse a standard header file name

• PRE06-C. Enclose header files in an inclusion guard

• PRE09-C. Do not replace secure functions with deprecated or obsolescent functions

Partial Adherence¶

• PRE00-C. Prefer inline or static functions to function-like macros

• PRE01-C. Use parentheses within macros around parameter names

• PRE02-C. Macro replacement lists should be parenthesized

Check Adherence¶

• PRE05-C. Understand macro replacement when concatenating tokens or performing stringification

• PRE07-C. Avoid using repeated question marks

• PRE10-C. Wrap multistatement macros in a do-while loop

• PRE11-C. Do not conclude macro definitions with a semicolon

• PRE12-C. Do not define unsafe macros

• PRE30-C. Do not create a universal character name through concatenation

• PRE31-C. Avoid side-effects in arguments to unsafe macros

• PRE32-C. Do not use preprocessor directives inside macro arguments

No Adherence¶

• PRE08-C. Guarantee that header file names are unique

Signals (SIG)¶

Error Handling (ERR)¶

Application Programming Interfaces (API)¶

Concurrency (CON)¶

Miscellaneous (MSC)¶
