If no private data provided for rdma_accept(3) the client may find it anyway.
During our experiments, it was a chunk of zeroed-out memory.

Thanks @osalyk for finding this issue! :-)

Proposal 1

  • if no data is provided send a non-empty known and documented pattern which indicates no data
  • when the other part receives this known pattern it does not pass it to the application

Proposal 2

  • make sure the issue is present in at least one of the currently supported OSes
