Rojin George has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1200078?usp=email ) Change subject: Fail NFSoRDMA mount for GSS Flavour krb5p ...................................................................... Fail NFSoRDMA mount for GSS Flavour krb5p To support krb5p for NFSoRDMA, 1> We do encryption of NFS response header + data buffers and copy encrypted data in single large buffer to send over wire as opaque bytes. 2> For RDMA we send nfs_headers and data seperately, so that we can do rdma_writes for data buffers, so single opaque buffer with header+data is not working. We can do the fix to copy this opaque buffer in RDMA registered memory and do rdma_send. But using krb5p has these overheads 1> CPU overhead to do encryption of all data buffers 2> Do buffer copies Which defeats the purpose of using RDMA transport. Hence until we have a proper optimised solution we plan to fail the RDMA mount for Krb5p.
