Hi, various ptrace testcases have been collected and packaged at: http://sourceware.org/systemtap/wiki/utrace/tests
Most of the tests target ptrace(2) implementation. Most of the ptrace(2) tests have ever failed only on the ptrace-by-utrace implementation. Testcases were contributed by the bugreporters, some of the build scripts come from Roland. The tested kernel versions are now only Fedora-centric, vanilla kernel versious should be filled-in there. New testcases are welcome, please follow the style (standalone .c files!). The provided testcases should prevent any utrace regressions in the future, unfortunately I saw at least one regression to happen before. Regards, Jan
