Allow process begin/end probes for unprivileged users.
2009-09-03 Dave Brolley <brolley@redhat.com>
* tapsets.cxx (visit_cast_op): Don't disallow unprivileged users.
Annotate synthesized function with /* unprivileged */.
* tapset-utrace.cxx (register_tapset_utrace): Call allow_unprivileged
for process begin and end probes.
* translate.cxx (translate_pass): Generate '#define STP_PRIVILEGED 1'
unless --unprivileged was specified.
* runtime/transport/transport.c: Don't define _stp_unprivileged_user.
* runtime/task_finder.c (__stp_utrace_attach_match_filename): Check
that _stp_uid equals the task euid when STP_PRIVILEGED is not defined.
(stap_start_task_finder): Likewise.
* runtime/staprun/staprun.c (insert_stap_module): Don't generate
module option _stp_unprivileged_user.
