Bug #: 13693
Summary: make probefunc unprivileged
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tapsets
AssignedTo: systemtap@sourceware.org
ReportedBy: fche@redhat.com
Classification: Unclassified
probefunc/probemod have had a funny history as to where they try to get
function name strings from. The probe-point-parsing variant is depended
upon from the para-callgraph* examples, and that part could be well enough
unprivileged. Other usages dip into the equivalent symdata(), which is
(rightfully?) privileged.
We should not so intermingle these. We could deprecate the privileged
parts of probefunc(), so that in 1.8+, unprivileged scripts can use it
(for probe-point-parsing only, or some cleaner equivalent). Or we could
write a new function to do only that, and adjust sample scripts.
