[comp.protocols.nfs] Help with NFS RPC's

mevawall@aludra.usc.edu (Shehzad Mevawalla) (11/21/90)

I am a graduate student and my group an I are working on a new cache 
consistency mechanism for SUN NFS (leases). We have all the code written
and all the modifications made to the NFS code to support our code.

One of these modifications was adding a new field to the file attributes
structure. However, now the client's RPC's don't even get on the network 
but it still thinks that it received some status back.

We know this because we built the kernel, with NFS DEBUG on, on both the
client and the server. So we can see the client making an RPC, but the
server never sees it. The next thing we see at the client is the RPC returning
a status (sometimes a good status and sometimes a "Can't decode args" status).

This happens even when the server is down. My question is how is this 
possible ? Did we miss something somewhere ? Any suggestions will be greatly
appreciated.
