From 5e8a3b7b558273fa06525f642fdf2d678dde85eb Mon Sep 17 00:00:00 2001 From: Dave Brolley Date: Thu, 3 Sep 2009 16:13:30 -0400 Subject: Allow process begin/end probes for unprivileged users. 2009-09-03 Dave Brolley * 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. --- translate.cxx | 2 ++ 1 file changed, 2 insertions(+) (limited to 'translate.cxx') diff --git a/translate.cxx b/translate.cxx index 65acd2ca..c0f7b48b 100644 --- a/translate.cxx +++ b/translate.cxx @@ -5210,6 +5210,8 @@ translate_pass (systemtap_session& s) if (ri.recursive) nesting += 10; // This is at the very top of the file. + if (! s.unprivileged) + s.op->newline() << "#define STP_PRIVILEGED 1"; s.op->newline() << "#ifndef MAXNESTING"; s.op->newline() << "#define MAXNESTING " << nesting; s.op->newline() << "#endif"; -- cgit
