As Robert Rex \u003crobert.rex@exasol.com\u003e pointed\nout this is wrong.\n\nYes, the re-parenting itself works correctly, but if the reparented task\nexits it needs -\u003eparent-\u003ensproxy-\u003epid_ns in do_notify_parent(), and if the\nmain thread is zombie its -\u003ensproxy was already cleared by\nexit_task_namespaces().\n\nIntroduce the new function, find_new_reaper(), which finds the new\n-\u003eparent for the re-parenting and changes -\u003echild_reaper if needed.  Kill\nthe now unneeded exit_child_reaper().\n\nAlso move the changing of -\u003echild_reaper from zap_pid_ns_processes() to\nfind_new_reaper(), this consolidates the games with -\u003echild_reaper and\nmakes it stable under tasklist_lock.\n\nAddresses http://bugzilla.kernel.org/show_bug.cgi?id\u003d11391\n\nReported-by: Robert Rex \u003crobert.rex@exasol.com\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nAcked-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Sukadev Bhattiprolu \u003csukadev@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

But this doesn\u0027t mean -\u003echildren list is empty, we\nmay have EXIT_DEAD tasks which are not visible to do_wait().  In that case\nthe subsequent forget_original_parent() will crash the kernel because it\nwill try to re-parent these tasks to the NULL reaper.\n\nEven if there are no childs, it is not good that forget_original_parent()\nuses reaper \u003d\u003d NULL.\n\nChange the code to set -\u003echild_reaper \u003d init_pid_ns.child_reaper instead.\nWe could use pid_ns-\u003eparent-\u003echild_reaper as well, I think this does not\nreally matter.  These EXIT_DEAD tasks are not visible to the new -\u003eparent\nafter re-parenting, they will silently do release_task() eventually.\n\nNote that we must change -\u003echild_reaper, otherwise\nforget_original_parent() will use reaper \u003d\u003d father, and in that case we\nwill hit the (correct) BUG_ON(!list_empty(\u0026father-\u003echildren)).\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nAcked-by: Sukadev Bhattiprolu \u003csukadev@linux.vnet.ibm.com\u003e\nAcked-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
