RFC 5666 Section 4.2 states: > When the peer detects an RPC-over-RDMA header version that it does > not support (currently this document defines only version 1), it > replies with an error code of ERR_VERS, and provides the low and > high inclusive version numbers it does, in fact, support. And: > When other decoding errors are detected in the header or chunks, > either an RPC decode error MAY be returned or the RPC/RDMA error > code ERR_CHUNK MUST be returned. The Linux NFS server does throw ERR_VERS when a client sends it a request whose rdma_version is not "one." But it does not return ERR_CHUNK when a header decoding error occurs. It just drops the request. To improve protocol extensibility, it should reject invalid values in the rdma_proc field instead of treating them all like RDMA_MSG. Otherwise clients can't detect when the server doesn't support new rdma_proc values.
