Previously, a la_activity audit event was generated before relocation processing completed. This does did not match what happened during initial startup in elf/rtld.c (towards the end of dl_main). It also caused various problems if an auditor tried to open the same shared object again using dlmopen: If it was the directly loaded object, it had a search scope associated with it, so the early exit in dl_open_worker_begin was taken even though the object was unrelocated. This caused the r_state == RT_CONSISTENT assert to fail. Avoidance of the assert also depends on reversing the order of r_state update and auditor event (already implemented in a previous commit). At the later point, args->map can be NULL due to failure, so use the assigned namespace ID instead if that is available. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
