Re: CFNetwork _handleTLSEvent crash
eskimo Jan 18, 2018 5:56 AM (in response to Jarosan)Thanks for opening a new thread about this. It is a different crash from the ones on that other thread. Alas, it seems to have a similar cause, namely a state error within CFNetwork. The specific cause of the crash is frame 5 of thread 8:
Thread 8 name: Thread 8 Crashed: 0 … __pthread_kill + 8 1 … pthread_kill$VARIANT$mp + 396 (pthread.c:1484) 2 … __abort + 152 (abort.c:128) 3 … abort + 152 (abort.c:99) 4 … __assert_rtn + 316 (assert.c:91) 5 … TCPIOConnection::_handleTLSEvent(nw_tls_context*, tls_handshake_message_t, void () block_pointer, bool) + 772 (TCPIOConnection.cpp:4628) 6 … __tcp_connection_set_tls_message_handler_on_nw_connection_block_invoke + 168 (tcp_connection.m:1799) 7 … __boringssl_session_trigger_callback_block_invoke + 136 (boringssl_session.c:2770) 8 … _dispatch_call_block_and_release + 24 (init.c:994) 9 … _dispatch_client_callout + 16 (object.m:502) 10 … _dispatch_queue_serial_drain$VARIANT$mp + 528 (inline_internal.h:2500) 11 … _dispatch_queue_invoke$VARIANT$mp + 340 (queue.c:5302) 12 … _dispatch_queue_serial_drain$VARIANT$mp + 200 (inline_internal.h:2539) 13 … _dispatch_queue_invoke$VARIANT$mp + 340 (queue.c:5302) 14 … _dispatch_root_queue_drain_deferred_wlh$VARIANT$mp + 404 (queue.c:5920) 15 … _dispatch_workloop_worker_thread$VARIANT$mp + 644 (source.c:2529) 16 … _pthread_wqthread + 932 (pthread.c:2207) 17 … start_wqthread + 4
TCPIOConnection
is a C++ class internal to CFNetwork that manages a TCP connection. It has determined that it’s in an erroneous state and that’s tripped an assert.We are tracking this problem internally (r. 33367468) but I can’t give you any estimate as to when it might be fixed.
I can assure you that this is very unlikely to be a problem in your code. This problem is affecting lots of different apps along with various system processes.
