Subject: [PATCH pynfs 0/3] MITM tool for NFS traffic on linux
Date: Wed, 27 May 2015 14:01:29 -0400 [thread overview]
Message-ID: <cover.1432749206.git.bcodding@redhat.com> (raw)
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.

Fix default arg order error on swig > 1.x
Add a tool for modification of NFS network traffic: itm
itm: add a handler that truncates READDIR response page data
