Commit Message

stsp March 2, 2023, 8:40 p.m. UTC
  This patch is an impl of dlload_audit_module() function discussed
in BZ #30127, and the test-case for it, called tst-loadaudit.
It checks the loading of audit module at run-time and makes sure
the pre-existing objects were "presented" to the new auditor via
la_objopen() call-back.

dlload_audit_module (const char *file, int flags)
"file" is a module file name
"flags" are reserved for future use.

As mentioned in BZ #30134, audit module list was in RELRO so this
patch makes it writable.

Test-suite run on x86_64 revealed no regressions.
