            Bug ID: 19043
           Summary: __bio_ino(), __rqstp_gid() and __rqstp_uid() can crash
                    the kernel
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tapsets
          Assignee: systemtap at sourceware dot org
          Reporter: mcermak at redhat dot com
  Target Milestone: ---

The __bio_ino(), __rqstp_gid() and __rqstp_uid() can crash the kernel with
invalid inputs. For instance: `stap -ge 'probe oneshot{ println(__bio_ino(-1))
}'` and similarly: __rqstp_gid(0) and __rqstp_uid(0).
