Refactor for clarity. Also, remove a stale comment. Commit ed94164398c9 ("nfsd: implement machine credential support for some operations") added support for SP4_MACH_CRED, so state_protect_a is no longer completely ignored. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2020-11-30NFSD: Add helper to decode OPEN's open_claim4 argumentChuck Lever
Refactor for clarity. Note that op_fname is the only instance of an NFSv4 filename stored in a struct xdr_netobj. Convert it to a u32/char * pair so that the new nfsd4_decode_filename() helper can be used. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2020-11-30NFSD: Replace READ* macros in nfsd4_decode_fattr()Chuck Lever
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. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
