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.

       --json=FILENAME
