Subject: [PATCH 0/2] minimal run-time audit support
Date: Tue, 21 Feb 2023 20:33:05 +0500 [thread overview]
Message-ID: <20230221153307.548259-1-stsp2@yandex.ru> (raw)
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.
