* | NFSD: Replace READ* macros in nfsd4_decode_fattr()Chuck Lever2020-11-301-18/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's be more careful to avoid overrunning the memory that backs the bitmap array. This requires updating the synopsis of nfsd4_decode_fattr(). Bruce points out that a server needs to be careful to return nfs_ok when a client presents bitmap bits the server doesn't support. This includes bits in bitmap words the server might not yet support. The current READ* based implementation is good about that, but that requirement hasn't been documented.

* | NFSD: Change the way the expected length of a fattr4 is checkedChuck Lever2020-11-301-23/+11
| | | | | | | | | | | | | | | | | | | | | | | | Because the fattr4 is now managed in an xdr_stream, all that is needed is to store the initial position of the stream before decoding the attribute list. Then the actual length of the list is computed using the final stream position, after decoding is complete. No behavior change is expected. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

* | NFSD: Replace the internals of the READ_BUF() macroChuck Lever2020-11-303-165/+30
| | | | | | | | | | | | | | | | | | | | Convert the READ_BUF macro in nfs4xdr.c from open code to instead use the new xdr_stream-style decoders already in use by the encode side (and by the in-kernel NFS client implementation). Once this conversion is done, each individual NFSv4 argument decoder can be independently cleaned up to replace these macros with C code. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* | NFSD: Add tracepoints in nfsd4_decode/encode_compound()Chuck Lever2020-11-302-2/+79
| | | | | | | | | | | | | | | | | | | | For troubleshooting purposes, record failures to decode NFSv4 operation arguments and encode operation results. trace_nfsd_compound_decode_err() replaces the dprintk() call sites that are embedded in READ_* macros that are about to be removed.

* | SUNRPC: Prepare for xdr_stream-style decoding on the server-sideChuck Lever2020-11-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A "permanent" struct xdr_stream is allocated in struct svc_rqst so that it is usable by all server-side decoders. A per-rqst scratch buffer is also allocated to handle decoding XDR data items that cross page boundaries. To demonstrate how it will be used, add the first call site for the new svcxdr_init_decode() API. As an additional part of the overall conversion, add symbolic constants for successful and failed XDR operations. Returning "0" is overloaded. Sometimes it means something failed, but sometimes it means success. To make it more clear when XDR decoding functions succeed or fail, introduce symbolic constants.
