That avoids the possibility of getting the "unrecognized" cookie. Test-case was enhanced to check for unrecognized cookies. This patch-set introduces the bare minimum functionality for working with audit modules at run-time. Patch1 fixes the check in dlmopen() which avoids loading solibs into the auditing namespace. But RTLD_NOLOAD was forgotten to check, and with that flags nothing gets loaded into auditing namespace, so dlmopen() should succeed and return the handle for auditing object. Patch2 adds dlload_audit_module() function and a test-case for it. -- 2.37.2
