|
|
+.SH SYNOPSIS
|
|
+.B ssdd
|
|
+.RI "[nforks] [niters]"
|
|
+.SH 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.
|
|
+.SH OPTIONS
|
|
+.B nforks
|
|
+number of tracer/tracee pairs to fork off.
|
|
+Default is 10.
|
|
+.br
|
|
+.TP
|
|
+.B niters
|
|
+number of PTRACE_SINGLESTEP iterations to
|
|
+do before declaring success, for each tracer/
|
|
+tracee pair set up. Default is 10,000.
