The 'perf probe' command allows kprobe to be inserted at any offset from a function start, which results in adding kprobes to unintended location. (example: perf probe do_fork+10000 is allowed even though size of do_fork is ~904). My previous patch https://lkml.org/lkml/2012/2/24/42 addressed the case where DWARF info was available for the kernel. This patch fixes the case where perf probe is used on a kernel without debuginfo available. Acked-by:
