NAME

       ssdd - have a tracer do a bunch of PTRACE_SINGLESTEPs

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.
