Detailed Description

Flow protection handling core functionality.

This subset of Flow protection macros is common to all code flow patterns to be protected.

Macro Definition Documentation

MCUX_CSSL_FP_DECL_NAME

#define MCUX_CSSL_FP_DECL_NAME	(		type,
			id )

Construct a name based on type and id.

Parameters

type	Indicator for the type of declaration.
id	Identifier for the flow protected entity.

Returns

CSSL flow protection entity name for given type and id.

MCUX_CSSL_FP_DECL_IMPL

#define MCUX_CSSL_FP_DECL_IMPL	(		type,
			id )

Generic flow protected entity declaration implementation.

Parameters

type	Indicator for the type of declaration.
id	Identifier for the flow protected entity.

Returns

CSSL flow protection entity declaration.

MCUX_CSSL_FP_ID_IMPL

#define MCUX_CSSL_FP_ID_IMPL

(

)

Generic identifier generator based on current line number.

Returns

Counter value based on the current line number.

MCUX_CSSL_FP_COUNTER_STMT_IMPL

#define MCUX_CSSL_FP_COUNTER_STMT_IMPL

(

statement

)

A statement which is only evaluated if a secure counter is used.

This macro can be applied to create or use supporting variables that are only needed if the active configuration uses a secure counter, to avoid warnings about unused variables.

This should only be required if a codebase is used with different backend classes for different build configurations.

Parameters

statement

The statement to be conditionally included.
