            Bug ID: 26307
           Summary: kernel commit ed66f991bb19 breaks module
                    initialization
           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: ---

staprun of any module after $subject commit causes a kernel BUG: (which
cleanishly terminates staprun rather than bringing down the system,
thankfully).  Cause is change to the internal module_sect_attr machinery, w=
hich
logic in runtime/linux/symbols.c STAPCONF_MODULE_SECT_ATTRS needs to adapt =
to.=20
Alternately, rip this whole part out; access module section attributes via =
some
other in-kernel interface, or get staprun to send updates and incidentally =
lose
ability to probe module-init functions.
