Synopsis
ssdd [-f|--forks NUM] [-h|--help] [-i|--iters NUM] [--json FILENAME]
Description
Have a tracer do a bunch of PTRACE_SINGLESTEPs against a tracee as fast as possible. Create several of these tracer/tracee pairs and see if they can be made to interfere with each other. The tracer waits on each PTRACE_SINGLESTEP with a waitpid(2) and checks that waitpid's return values for correctness.
Options
- -f, --forks=NUM
number of tracer/tracee pairs to fork off.
Default is 10.- -h, --help
Display usage
- -i, --iters=NUM
number of PTRACE_SINGLESTEP iterations to do before declaring success, for each tracer tracee pair set up.
Default is 10,000.- --json=FILENAME
Write final results into FILENAME, JSON formatted.
