The following bugs has been backported to RHEL 7.2 on our request: - BZ cms-sw#13862 // Reuse of cached stack can cause bounds overrun of thread DTV - BZ cms-sw#17090 // Assertion failure (map->l_tls_modid == cnt) when dlopen()ing initial-exec TLS shared objects under certain circumstances - BZ cms-sw#17620 // DTV_SURPLUS limits loading of Static TLS-requiring modules in multi-threaded programs - BZ cms-sw#17621 // DTV update for Static TLS dlopened modules is racy - BZ cms-sw#17628 // nptl_db's td_thr_tls* don't check DTV generation There is no need to continue shipping a custom version of dynamic loader for CentOS 7.2.1511 or above. All the fixes are within glibc-rh1189278.patch and glibc-rh1202952.patch on glibc source RPM. Will resolve cmsRun segfaults on CentOS 7.2.1511.
