NAME

       ssdd - have a tracer do a bunch of PTRACE_SINGLESTEPs

SYNOPSIS

       ssdd [nforks] [niters]

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

       nforks number of tracer/tracee pairs to fork off.  Default is 10.

       niters number  of  PTRACE_SINGLESTEP  iterations  to do before declaring success, for each tracer/ tracee
              pair set up. Default is 10,000.
