A truncated cb_compound request will cause the client to decode null or data from a previous callback for nfs4.1 backchannel case, or uninitialized data for the nfs4.0 case. This is because the path through svc_process_common() advances the request's iov_base and decrements iov_len without adjusting the overall xdr_buf's len field. That causes xdr_init_decode() to set up the xdr_stream with an incorrect length in nfs4_callback_compound(). Fixing this for the nfs4.1 backchannel case first requires setting the correct iov_len and page_len based on the length of received data in the same manner as the nfs4.0 case. Then the request's xdr_buf length can be adjusted for both cases based upon the remaining iov_len and page_len.
