             Bug #: 14057
           Summary: ERROR: Your privilege credentials (stapsys) are
                    insufficient to run this module (stapdev required).
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sourceware.org
        ReportedBy: mjw@redhat.com

    Classification: Unclassified


commit 429a4963c958e082c1199c5c3266c45bd4122907
Author: Dave Brolley <brolley@redhat.com>

    BZ 813323: stapusr-only users no longer able to run unsigned modules in
/lib

    - Elevate the user's privilege level to stapdev when the module is loaded
fr
      /lib/modules/`uname -r`/systemtap.
    - Suppress error messages about failure to verify the module's signature
      when a signature is not required.

After this commit I get the following when using stap as root:
sudo /home/mark/install/systemtap/bin/stap
/home/mark/src/systemtap/testsuite/systemtap.base/backtrace.stp 
ERROR: Your privilege credentials (stapsys) are insufficient to run this module
(stapdev required).
WARNING: /home/mark/install/systemtap/bin/staprun exited with status: 1
Pass 5: run failed.  Try again with another '--vp 00001' option.

This results in lots and lots of sudo make installcheck failures. This is with
systemtap from git on Red Hat Enterprise Linux Workstation release 6.2
(Santiago) i686. Reverting the above patch makes everything work again.
