            Bug ID: 21890
           Summary: bpf uprobes support
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

Current bpf code can handle kprobes & kretprobes.  It should not be hard to
bring up uprobes/uretprobes; the translator's side is almost identical.  The
.bo symbol-name encoding would be fine too, as long as path names are included.
 The stapbpf kprobe* functions just(tm) need to be forked or parametrized into
uprobe* ones (including those that manipulate the /sys/kernel/debug/tracing
files).
