Bug ID: 28129
Summary: Unnecessary check DT_DEBUG in ld.so
Product: glibc
Version: 2.34
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
rtld.c has
/* Fill in the pointer in the dynamic linker's own dynamic section, in
case you run gdb on the dynamic linker directly. */
if (GL(dl_rtld_map).l_info[DT_DEBUG] != NULL)
GL(dl_rtld_map).l_info[DT_DEBUG]->d_un.d_ptr = (ElfW(Addr)) r;
But linker never generates DT_DEBUG in shared libraries. It should be removed
or linker should add a new option to generate DT_DEBUG in shared libraries.

Lu <hjl.tools@gmail.com> Date: Mon Aug 2 13:52:36 2021 -0700 ld.so: Don't fill the DT_DEBUG entry in ld.so [BZ #28129] Linker creates the DT_DEBUG entry only in executables. Don't fill the non-existent DT_DEBUG entry in ld.so with the run-time address of the r_debug structure.
