The NFSv2/NFSv3 server does not handle zero length WRITE requests correctly
The NFSv2 and NFSv3 servers do not handle WRITE requests for 0 bytes
correctly. The specifications indicate that the server should accept the
request, but it should mostly turn into a no-op. Currently, the server
will return an XDR decode error, which it should not.
Attached is a patch which addresses this issue. It also adds some boundary
checking to ensure that the request contains as much data as was requested
to be written. It also correctly handles an NFSv3 request which requests
to write more data than the server has stated that it is prepared to
handle. Previously, there was some support which looked like it should
work, but wasn't quite right.
