[Bug runtime/9937] verify user-space build-ids


------- Additional Comments From wenji dot huang at oracle dot com  2009-03-27 03:33 -------
Created an attachment (id=3850)
 --> (http://sourceware.org/bugzilla/attachment.cgi?id=3850&action=view)
Updated patch

Changed to the old one.
1. Once build-id check finished, early return
2. Trigger warning if build-id doesn't match and make finder.callback return.
3. build-id checking limited to map_p in vma.callback
4. Use module path to compare vm_path. (thanks to Mark Wielaard)

Did some tests on FC10. Looks fine.

Need to be improve:
1. Still need to hook stap_uprobe_process_found explicitly for an EXEC
finder.callback since vma.callback == NULL.
2. The annoying problem is that the validation procedure will be repeated 
many times. That depends on callbacks. 

Any idea?
