Document: draft-ietf-nfsv4-minorversion2-dot-x-39.txt Reviewer: Elwyn Davies Review Date: 2015-12-13 IETF LC End Date: 2015-12-09 IESG Telechat date: (if known) - Summary: Ready with nits. The XDR specification appears to be a superset of the v4.1 XDR specification and combines a correction of the five remaining discrepancies between v4.1 and v4.0bis ( definition and use of the NFS4_OTHER_SIZE constant, addition and use of the ascii_REQUIRED4 type, modification of the typedef of linktext4). The additions of the 4.2 interface appears to match the specification in draft-ietf-nfsv4-minorversion2-39 except for two attribute typedef items mentioned below. One discrepancy would have no operational effect as the type used in the other draft is an alias for the type used here but the clone_blksize error changes the size of the type. I have checked that the extracted code is accepted by rpcgen and generates files as expected. Major issues: None Minor issues: None Nits/editorial comments: Observation: It might be useful to note that this XDR specification is fully upwards compatible with the v4.0bis with the minor exception of the clientaddr4 structure which has been replaced by (strictly, aliased to) netaddr4 which has the same members with the same purposes but the names have changed (r_netid -> na_r_netid, r_addr ->na_r_addr). This effectively fully reconverges the v4.0bis and v4.1 strands of the XDR.
