I am speaking about descriptors in systemd pam module. Application which use pam can not control it. Because of: session_fd = dup(session_fd); in pam-module.c we have now descriptor which does not have O_CLOEXEC set. So it will not be closed automatically during exec of children processes and because of this logind will not know that process which opened pam session exited. Sergei
