This paper describes a system and annotation language, MECA, for checking security rules. MECA is expressive and designed for checking real systems. It provides a variety of practical constructs to effectively annotate large bodies of code. For example, it allows programmers to write programmatic annotators that automatically annotate large bodies of source code. As another example, it lets programmers use general predicates to determine if an annotation is applied; we have used this ability to

Once code is annotated, MECA propagates annotations aggressively, allowing a single manual annotation to derive many additional annotations (e.g., over one hundred in our experiments) freeing programmers from the heavy manual effort required by most past systems. MECA is effective. Our most thorough case study was a user-pointer checker that used 75 annotations to check thousands of declarations in millions of lines of code in the Linux system. It found over forty errors, many of which were serious, while only having eight false positives.
