2023-10-16NFSD: Clean up nfsd4_encode_stateid()Chuck Lever1-16/+20
Update the encoder function name to match the type name, as is the convention with other such encoder utility functions, and with nfsd4_decode_stateid4(). Make the @stateid argument a const so that callers of nfsd4_encode_stateid4() in the future can be passed const pointers to structures. Since the compiler is allowed to add padding to structs, use the wire (spec-defined) size when reserving buffer space.

2023-10-16NFSD: Add nfsd4_encode_count4()Chuck Lever2-4/+10
This is a synonym for nfsd4_encode_uint32_t() that matches the name of the XDR type. It will get at least one more use in a subsequent patch. Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2023-10-16NFSD: Rename nfsd4_encode_fattr()Chuck Lever1-10/+13
For better alignment with the specification, NFSD's encoder function name should match the name of the XDR data type. Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2023-10-16NFSD: Use a bitmask loop to encode FATTR4 resultsChuck Lever1-287/+146
The fattr4 encoder is now structured like the COMPOUND op encoder: one function for each individual attribute, called by bit number. Benefits include: - The individual attributes are now guaranteed to be encoded in bitmask order into the send buffer - There can be no unwanted side effects between attribute encoders - The code now clearly documents which attributes are /not/ implemented on this server Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
