We have noticed that when rdma_resolve_addr is provided with src
address, the rdma cm does an implicit --address-- (=ip/port) binding,
which for example has the side effect of disallowing two processes to
call rdma_resolve_addr() with the same src port.
Does this implicit binding mimics the network stack behavior
under similar flow when socket are used?
Specifying a source address with rdma_resolve_addr is similar to calling
socket bind. I can't think of a reason why an app would want to specify
a source port when calling rdma_resolve_addr. Specifying a source
address (wild card port) allows binding to a specific RDMA device.
