Subject: [PATCH v2 0/2] minimal run-time audit support
Date: Thu, 23 Feb 2023 13:09:12 +0500 [thread overview]
Message-ID: <20230223080914.2961911-1-stsp2@yandex.ru> (raw)
Changes in v2: address the review comment of Jonathon Anderson:
Add per-linkmap l_naudit counter to make sure each object is audited
only with the modules loaded before it. 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.
