            Bug ID: 25579
           Summary: detect kernel lockdown/secureboot in effect
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

https://bugzilla.redhat.com/show_bug.cgi?id=3D1638874 indicates modern kern=
els
activate a lockdown mode for kernels running under secureboot-enforcing mod=
e,
which may prevent normal stap modules from loading/running.  Once the kernel
exposes this state to unprivileged stap, we'll need to adopt the translator=
 to
invoke the secureboot-signing mode implicitly.  This logic is in the
systemtap_session::modules_must_be_signed() function.
