From 484e672ddabe0a919a692520e6ac8f2580866235 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 30 Jun 2021 17:33:57 -0300 Subject: elf: Do not fail for failed dlmopen on audit modules (BZ #28061) The dl_main sets the LM_ID_BASE to RT_ADD just before starting to add load new shared objects. The state is set to RT_CONSISTENT just after all objects are loaded. However if a audit modules tries to dlmopen an inexistent module, the _dl_open will assert that the namespace is in an inconsistent state. This is different than dlopen, since first it will not use LM_ID_BASE and second _dl_map_object_from_fd is the sole responsible to set and reset the r_state value. So the assert on _dl_open can not really be seen if the state is consistent, since _dt_main resets it. This patch removes the assert. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.
