The NFS community has standardized RPC-over-TLS as part of an effort to prepare for running NFS on QUIC transports. https://datatracker.ietf.org/doc/draft-ietf-nfsv4-rpc-tls/ Towards that end, an in-kernel QUIC would need a way to perform transport security handshakes. Tempesta has one we are looking closely at -- it can support both TLS and QUIC. There's more work to be done to address the ways in which QUIC is different than existing transports (eg. its support for streams and transactions); however if Linux were to gain an in-kernel QUIC implementation, there is interest in seeing NFS use it. -- Chuck Lever
