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

Write final results into FILENAME, JSON formatted.
