if nvmeOF target does not exist, jNVMf will hand there instead report correct error then quit

[gwnet]

1. make sure IP and RDMA network is OK. but does not setup nvme target.
   2, run benchmark with below steps

then the application will hang at below code: at the endpoint.connect part. it will hang, never return.

FabricsConnectResponseCqe connect(long timeout, TimeUnit timeoutUnit) throws IOException {
NativeBuffer buffer = new NativeByteBuffer(
ByteBuffer.allocateDirect(RdmaCmRequestPrivateData.SIZE));
RdmaCmRequestPrivateData privateData = new RdmaCmRequestPrivateData(buffer);
privateData.setQueueId(queueId);
privateData.setRdmaQpReceiveQueueSize(submissionQueueSize);
privateData.setRdmaQpSendQueueSize((short) (submissionQueueSize - 1));
this.endpoint.getConnParam().setPrivate_data(buffer.getAddress());
this.endpoint.getConnParam().setPrivate_data_len((byte) RdmaCmRequestPrivateData.SIZE);
InetSocketAddress socketAddress = controller.getTransportId().getAddress();
try {
//FIXME: rejected requests are not handled by DiSNI
//FIXME: check for overflow
endpoint.connect(socketAddress, (int)TimeUnit.MILLISECONDS.convert(timeout, timeoutUnit));
} catch (Exception exception) {
throw new IOException(exception);
}

It will after the timeout. Reduce the timeout if you want it to happen earlier. Otherwise if that does not work open a ticket in the Disni repository.

[PepperJo]

BTW you can set the timeout with Controller.connect there is an overload which allows you to set it: https://github.com/zrlio/jNVMf/blob/master/src/main/java/com/ibm/jnvmf/Nvme.java

got it. thank you so much!~, timeout is Ok so far. I will see if we need fail immediately later. can you help raise ticket on libdisni?
