This originated from a gdb\nbugreport (the fact gdb was segfaulting the task wasn\u0027t a kernel bug), but\nI just incidentally noticed the gdb bug triggered a real kernel bug as\nwell.\n\nMost threads hangs in exit_mm because the core_dumping is still going, the\ncore dumping hangs because the stopped task doesn\u0027t exit, the stopped task\ncan\u0027t wakeup because it has SIGNAL_GROUP_EXIT set, hence the deadlock.\n\nTo me it seems that the problem is that the force_sig_specific(SIGKILL) in\nzap_threads is a noop if the task has PF_PTRACED set (like in this case\nbecause gdb is attached). The __ptrace_unlink does nothing because the\nsignal-\u003eflags is set to SIGNAL_GROUP_EXIT|SIGNAL_STOP_DEQUEUED (verified).\n\nThe above info also shows that the stopped task hit a race and got the stop\nsignal (presumably by the ptrace_attach, only the attach, state is still\nTASK_STOPPED and gdb hangs waiting the core before it can set it to\nTASK_TRACED) after one of the thread invoked the core dump (it\u0027s the core\ndump that sets signal-\u003eflags to SIGNAL_GROUP_EXIT).\n\nSo beside the fact nobody would wakeup the task in __ptrace_unlink (the\nstate is _not_ TASK_TRACED), there\u0027s a secondary problem in the signal\nhandling code, where a task should ignore the ptrace-sigstops as long as\nSIGNAL_GROUP_EXIT is set (or the wakeup in __ptrace_unlink path wouldn\u0027t be\nenough).\n\nSo I attempted to make this patch that seems to fix the problem. There\nwere various ways to fix it, perhaps you prefer a different one, I just\nopted to the one that looked safer to me.\n\nI also removed the clearing of the stopped bits from the zap_other_threads\n(zap_other_threads was safe unlike zap_threads). I don\u0027t like useless\ncode, this whole NPTL signal/ptrace thing is already unreadable enough and\nfull of corner cases without confusing useless code into it to make it even\nless readable. And if this code is really needed, then you may want to\nexplain why it\u0027s not being done in the other paths that sets\nSIGNAL_GROUP_EXIT at least.\n\nEven after this patch I still wonder who serializes the read of\np-\u003eptrace in zap_threads.\n\nPatch is called ptrace-core_dump-exit_group-deadlock-1.\n\nThis was the trace I\u0027ve got:\n\ntest T ffff81003e8118c0 0 14305 1 14311 14309
