What follows is a small tool I think may be convenient to test and reproduce certain types of bugs that are difficult to create from above the filesystem, but are clearly problematic and have well-defined network triggers. Anna's recent BAD_STATEID on WRITES with delegation is a good example of that. This tool uses netfilters NFQUEUE target to allow a linux host to modify the NFS network traffic between existing clients and servers. In that sense, it is very similar to nfs-proxy, however I find it to be much more convenient to use, as it can be quickly inserted and removed from an existing network conection.
