[libfabric-users] sockets provider question

[Jose, Jithin]

Hi Howard,

>libfabric:sockets:av:sock_check_table_in():228<debug> AV-INSERT:dst_addr: family: 2, IP is 10.128.0.9, port: 0

From the logs, it looks like the address inserted to AV table has port = 0. Can you double check this?
May be we should add some error-checking here to catch these.

I think the connect() call is failing because of this:

>libfabric:sockets:ep_ctrl:sock_ep_connect():419<debug> Connecting to:
>10.128.0.9:0 <http://10.128.0.9:0>

>Are there known problems with the sockets provider and send-to-self style send/recv
>using FI_EP_RDM?

I am not aware of any issues with send-to-self send/recv with sockets-provider.
