SUNRPC: Teach server to use xprt_sock_sendmsg for socket sends

2020-03-16T16:04:33Z

xprt_sock_sendmsg uses the more efficient iov_iter-enabled kernel socket API, and is a pre-requisite for server send-side support for TLS. Note that svc_process no longer needs to reserve a word for the stream record marker, since the TCP transport now provides the record marker automatically in a separate buffer. The dprintk() in svc_send_common is also removed. It didn't seem crucial for field troubleshooting. If more is needed there, a trace point could be added in xprt_sock_sendmsg().

nfsd: Fix NFSv4 READ on RDMA when using readv

2020-03-16T16:04:31Z

svcrdma expects that the payload falls precisely into the xdr_buf page vector. This does not seem to be the case for nfsd4_encode_readv(). This code is called only when fops->splice_read is missing or when RQ_SPLICE_OK is clear, so it's not a noticeable problem in many common cases. Add new transport method: ->xpo_read_payload so that when a READ payload does not fit exactly in rq_res's page vector, the XDR encoder can inform the RPC transport exactly where that payload is, without the payload's XDR pad. That way, when a Write chunk is present, the transport knows what byte range in the Reply message is supposed to be matched with the chunk. Note that the Linux NFS server implementation of NFS/RDMA can currently handle only one Write chunk per RPC-over-RDMA message. This simplifies the implementation of this fix.

SUNRPC: Allow further customisation of RPC program registration

2019-04-24T13:46:35Z

Add a callback to allow customisation of the rpcbind registration. When clients have the ability to turn on and off version support, we want to allow them to also prevent registration of those versions with the rpc portmapper. Signed-off-by: Trond Myklebust Signed-off-by: J. Bruce Fields

SUNRPC/nfs: Fix return value for nfs4_callback_compound()

2019-04-24T13:46:34Z

RPC server procedures are normally expected to return a __be32 encoded status value of type 'enum rpc_accept_stat', however at least one function wants to return an authentication status of type 'enum rpc_auth_stat' in the case where authentication fails. This patch adds functionality to allow this. Fixes: a4e187d83d88 ("NFS: Don't drop CB requests with invalid principals") Signed-off-by: Trond Myklebust Signed-off-by: J. Bruce Fields
