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 (NOTLB)\nffff810058ccdde8 0000000000000082 000001f4000037e1 ffff810000000013\n 00000000000000f8 ffff81003e811b00 ffff81003e8118c0 ffff810011362100\n 0000000000000012 ffff810017ca4180\nCall Trace:\u003cffffffff801317ed\u003e{try_to_wake_up+893} \u003cffffffff80141677\u003e{finish_stop+87}\n \u003cffffffff8014367f\u003e{get_signal_to_deliver+1359} \u003cffffffff8010d3ad\u003e{do_signal+157}\n \u003cffffffff8013deee\u003e{ptrace_check_attach+222} \u003cffffffff80111575\u003e{sys_ptrace+2293}\n \u003cffffffff80131810\u003e{default_wake_function+0} \u003cffffffff80196399\u003e{sys_ioctl+73}\n \u003cffffffff8010dd27\u003e{sysret_signal+28} \u003cffffffff8010e00f\u003e{ptregscall_common+103}\n\ntest D ffff810011362100 0 14309 1 14305 14312 (NOTLB)\nffff810053c81cf8 0000000000000082 0000000000000286 0000000000000001\n 0000000000000195 ffff810011362340 ffff810011362100 ffff81002e338040\n ffff810001e0ca80 0000000000000001\nCall Trace:\u003cffffffff801317ed\u003e{try_to_wake_up+893} \u003cffffffff8044677d\u003e{wait_for_completion+173}\n \u003cffffffff80131810\u003e{default_wake_function+0} \u003cffffffff80137435\u003e{exit_mm+149}\n \u003cffffffff801381af\u003e{do_exit+479} \u003cffffffff80138d0c\u003e{do_group_exit+252}\n \u003cffffffff801436db\u003e{get_signal_to_deliver+1451} \u003cffffffff8010d3ad\u003e{do_signal+157}\n \u003cffffffff8013deee\u003e{ptrace_check_attach+222} \u003cffffffff80140850\u003e{specific_send_sig_info+2\n\n \u003cffffffff8014208a\u003e{force_sig_info+186} \u003cffffffff804479a0\u003e{do_int3+112}\n \u003cffffffff8010e308\u003e{retint_signal+61}\ntest D ffff81002e338040 0 14311 1 14716 14305 (NOTLB)\nffff81005ca8dcf8 0000000000000082 0000000000000286 0000000000000001\n 0000000000000120 ffff81002e338280 ffff81002e338040 ffff8100481cb740\n ffff810001e0ca80 0000000000000001\nCall Trace:\u003cffffffff801317ed\u003e{try_to_wake_up+893} \u003cffffffff8044677d\u003e{wait_for_completion+173}\n \u003cffffffff80131810\u003e{default_wake_function+0} \u003cffffffff80137435\u003e{exit_mm+149}\n \u003cffffffff801381af\u003e{do_exit+479} \u003cffffffff80142d0e\u003e{__dequeue_signal+558}\n \u003cffffffff80138d0c\u003e{do_group_exit+252} \u003cffffffff801436db\u003e{get_signal_to_deliver+1451}\n \u003cffffffff8010d3ad\u003e{do_signal+157} \u003cffffffff8013deee\u003e{ptrace_check_attach+222}\n \u003cffffffff80140850\u003e{specific_send_sig_info+208} \u003cffffffff8014208a\u003e{force_sig_info+186}\n \u003cffffffff804479a0\u003e{do_int3+112} \u003cffffffff8010e308\u003e{retint_signal+61}\n\ntest D ffff810017ca4180 0 14312 1 14309 13882 (NOTLB)\nffff81005d15fcb8 0000000000000082 ffff81005d15fc58 ffffffff80130816\n 0000000000000897 ffff810017ca43c0 ffff810017ca4180 ffff81003e8118c0\n 0000000000000082 ffffffff801317ed\nCall Trace:\u003cffffffff80130816\u003e{activate_task+150} \u003cffffffff801317ed\u003e{try_to_wake_up+893}\n \u003cffffffff8044677d\u003e{wait_for_completion+173} \u003cffffffff80131810\u003e{default_wake_function+0}\n \u003cffffffff8018cdc3\u003e{do_coredump+819} \u003cffffffff80445f52\u003e{thread_return+82}\n \u003cffffffff801436d4\u003e{get_signal_to_deliver+1444} \u003cffffffff8010d3ad\u003e{do_signal+157}\n \u003cffffffff8013deee\u003e{ptrace_check_attach+222} \u003cffffffff80140850\u003e{specific_send_sig_info+2\n\n \u003cffffffff804472e5\u003e{_spin_unlock_irqrestore+5} \u003cffffffff8014208a\u003e{force_sig_info+186}\n \u003cffffffff804476ff\u003e{do_general_protection+159} \u003cffffffff8010e308\u003e{retint_signal+61}\n\nSigned-off-by: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Linus Torvalds \u003ctorvalds@osdl.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6dd69f1061bfdeca230509b173438e0731bff767", "tree": "66094a2fdf02fd808b0661cc2a26c6ff64d1c590", "parents": [ "19a4fcb531659f2f7d18b5d04cee039176e9540d" ], "author": { "name": "Vadim Lobanov", "email": "vlobanov@speakeasy.net", "time": "Sun Oct 30 15:02:18 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 30 17:37:19 2005 -0800" }, "message": "[PATCH] Unify sys_tkill() and sys_tgkill()\n\nThe majority of the sys_tkill() and sys_tgkill() function code is\nduplicated between the two of them.
