            Bug ID: 26234
           Summary: utrace_derived_probes (and others?) being silently
                    ignored by bpf backend
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bpf
          Assignee: systemtap at sourceware dot org
          Reporter: me at serhei dot io
  Target Milestone: ---

process.begin probes are triggered by the SystemTap's runtime's task_finder
component. I'm not sure yet if BPF provides any equivalent functionality at=
 all
-- will investigate further. The examples I can find so far would run the p=
robe
in the wrong context.

In that case, to start with, we really should print a warning instead of
silently ignoring the probe. {Internally, the process.begin probe is added =
to
the utrace_derived_probes array, which isn't processed by the BPF backend..=
..}

{The same might be true for others.}
