* Refactor AIO logic to close numerous races and reduce complexity.Garrett D'Amore2017-08-04
| | | | | | | | | This passes valgrind 100% clean for both helgrind and deep leak checks. This represents a complete rethink of how the AIOs work, and much simpler synchronization; the provider API is a bit simpler to boot, as a number of failure modes have been simply eliminated. While here a few other minor bugs were squashed.
* More reliable taskq fini; avoids deadlock during shutdown.Garrett D'Amore2017-08-02

* Eliminate the separate AIO wake callback, making nni_aio_waitGarrett D'Amore2017-07-21

* Simpler taskq API.Garrett D'Amore2017-07-21
| | | | | | | The queue is bound at initialization time of the task, and we call entries just tasks, so we don't have to pass around a taskq pointer across all the calls. Further, nni_task_dispatch is now guaranteed to succeed.
* Yet more race condition fixes.Garrett D'Amore2017-07-20
| | | | | | | | | We need to remember that protocol stops can run synchronously, and therefore we need to wait for the aio to complete. Further, we need to break apart shutting down aio activity from deallocation, as we need to shut down *all* async activity before deallocating *anything*. Noticed that we had a pipe race in the surveyor pattern too.
* Always run the AIO completion logic.Garrett D'Amore2017-07-19
| | | | | | | | We have seen some yet another weird situation where we had an orphaned pipe, which was caused by not completing the callback. If we are going to run nni_aio_fini, we should still run the callback (albeit with a return value of NNG_ECANCELED or somesuch) to be sure that we can't orphan stuff.
