Before this change: $ strace -D -p1 strace: -D and -p are mutually exclusive options Process 1 detached <==== WRONG! (and we try to SIGSTOP it!!!) * defs.h: Change the meaning of TCB_ATTACHED: now it means "this tracee is attached to us". Add TCB_STRACE_CHILD: "this tracee is our child". * strace.c (kill_save_errno): Move up. No code changes. (process_opt_p_list): Don't set TCB_ATTACHED on new tcb. (startup_attach): Change how we work with TCB_ATTACHED. Set TCB_STRACE_CHILD on -D. (startup_child): Use kill_save_errno instead of kill. Set TCB_ATTACHED and TCB_STRACE_CHILD on attached strace child. If we are in -D case, don't set TCB_ATTACHED (we aren't attached yet). (detach): do not do PTRACE_DETACH if TCB_ATTACHED is not set. (cleanup): Check TCB_STRACE_CHILD instead of TCB_ATTACHED. (trace): Likewise. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
