commit 86229a5533de13b6ac6eeb34d9ea24e7cfb64faa
Author: David Smith <dsmith@redhat.com>
Date: Fri Oct 1 12:56:54 2010 -0500
Fixed BZ634242 by always looking up pids in the global namespace.
* runtime/uprobes2/uprobes.c (uprobe_get_tg_leader): Always look up the
pid in the global pid namespace. From Roland McGrath
<roland@redhat.com>
(uprobe_fork_uproc): Ditto. From Roland McGrath <roland@redhat.com>
(uprobe_report_clone): If two processes are are sharing the same memory
space (CLONE_VM) don't remove probes, since that will remove the probes
from both processes.
* tapsets.cxx (emit_module_exit): Make sure we always look up pids
in the global pid namespace, not in any private pid namespace.
* runtime/uprobes-common.c (stap_uprobe_change_plus): Ignore EEXIST
errors.
