this is what I am observing with v4.0 and v4.1.
sometimes, mostly on RPCSEC_GSS_DESTROY,
in the PC calls missing verifier. This is against my
server and linux server.
Packets attached. Look at them packet 15.
100% reproducible.
I tried vanilla 2.6.39 and 3.0.0-rc3 from
git://linux-nfs.org/~trondmy/nfs-2.6.git

Looking at the code quickly:
The only place I see gss headers encoded is in gss_marshal(), which
unconditionally encodes the verifier.
So the length must be getting messed up after that?
I don't see it....
