Hi All,
I have implemented shell scripts that helps me to narrow down a faulty
probe that causes problem/crash, while debugging systemtap issues. As
per the discussion in weekly systemtap meeting dated 12th March 2009, I
am attaching these scripts (kp_bisect.tgz) that may help us in
identifying probes that can be a potential candidate for blacklist.
These scripts will help user to extract probes (probe function name)
from stap generated C module and test plain kprobes/kretprobes allowing
user to run bisect-like functionality to narrow down to a single faulty
probe. It does handle ".call" and ".return" probes.
Can someone can take look at these scripts and see if these can be used
as a base for automating the process of testing kprobes for black/white
list generation? The file "README.txt" describes the steps to use these
scripts.
Thanks,
-Mahesh.
