Re: [HPDD-discuss] How should a LND handle a LNet get request?

Hello, the LND which I am implementing is now capable of handling LNET_MSG_PUT. Or, at least, the LNet self test can create a group of nodes. Now it is time for a real ping test, which requires LNET_MSG_GET messages. It is not clear to me, how to handle that kind of LNet messages. The LNDs send function get called with to send a get message, but without any attached data (in this message, kiov and iov and the number of iov is 0). So, the LND send this messages header to the node from where the data should be fetched. On this node, the header is passed to LNet for parsing. LNet calls the receive LNDs function with a LNET_MSG_REPLY, this time with data attached. Now, I am not sure what to do with that reply message. Should it be send back to the requesting node, in order to get information where the data should be placed? Or is this information already in the get request? I tried to find documentation about this, or tried to understand the how this is done by other LNDs (including the loopback device), but it was not very clear (to me).
