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.
