             Bug #: 14572
           Summary: Restrict stapdyn's set of available probes
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
        AssignedTo: systemtap@sourceware.org
        ReportedBy: jistone@redhat.com
    Classification: Unclassified


The translator needs to restrict the set of available probes for
--runtime=dyninst.  Right now, the bad/unported probe types will make it
through pass-3 unhindered, but will surely fail to compile as userspace code. 
(Note that there's no security risk in this, as we're operating entirely
without privilege, but it's broken nonetheless.)

Eventually, the usable probes will probably look similar to --unprivileged, but
for now only begin/end/error and uprobes-like process.* probes are implemented.

Commit 3e784e8 did a lot of this work, which can be seen in "stap
--dump-probe-types --runtime=dyninst".  There are still some listed there that
aren't supported, but we may wish for, like timers and utrace-like probes.
