      "message": "Eliminate deadlock in forked child due to delayed resetting mutex lock\n\nFor some program implementation, the pattern like below, calling \npthread_atfork to register atfork interfaces.\n\n    pthread_atfork(\u0026atfork_prepare, \u0026atfork_parent, \u0026atfork_child);\n\nWhen the program is expected to reopen the shared library\u0027s handle \ninherited from parent in child process. Maybe, dlclose is called in \natfork_child to release the shared library handle before reopen it. \nThen, dlclose will indrectly call _cxa_finalize and finaly call \n__unregister_atfork when dso is not NULL.\n\n    atfork_child() -\u003e dlclose() -\u003e __on_dlclose() \n    \t-\u003e __cxa_finalize() -\u003e __unregister_atfork(dso)\n\nIn __unregister_atfork, firstly, it try to hold the g_atfork_list_mutex \nlock to operate the g_atfork_list. Due to the registered atfork_child is\nexecuted before resetting g_atfork_list_mutex lock in child, the child \nprocess will be blocked here because of deadlock.\n\nTest: bionic-unit-tests32 --gtest_filter\u003dpthread.pthread_atfork_child_with_dlclose \nwithout the fixing, the test will be timeout.\n\nChange-Id: I35d3001682c836e0955d6d681bc5f9297fad0c7b\nSigned-off-by: Mingwei Shi \u003cmingwei.shi@intel.com\u003e\nSigned-off-by: Qiming Shi \u003cqiming.shi@intel.com\u003e\nSigned-off-by: Chao Xie \u003cchao.xie@intel.com\u003e\n"
