Is there some way to tell what version of kprobes a kernel is running?
For example, the kretprobe sys_execve bug has been fixed and 2.6.15 has
the fix in it. So do RHEL4 kernels after 2.6.9-17. All other kernels,
including the non-test FC4 kernels do not have it and many of my syscall
tests crash the kernel.
So sys_execve should be back on the blacklist, but what to check for?
The problem is only going to get worse as kprobes changes rapidly with
kprobe-booster, djprobes, and user probes. There will be probably bugs
in some versions and new features will become available. People will
want to backport these fixes and features into older kernels.
