(I tried both with and without modifying your uint32_t size
to a 'int32_t size' to correct the signedness of the argument)
Get ahold of me in IRC and let's get this figured out. I've got a
debugger attached.

That actually broke everything (including Linux trying to mount NFS).
I've modified it slightly to be:

&objp->data.data_len, NFS3_FHSIZE))

&objp->data.data_len))
return FALSE;

(i.e. only call the xdr_opaque function if the xdr_bytes decode fails)
Nah, that won't work. The xdr_* functions are modifying the position of
the cursor in the XDR-stream. Subsequent reads will continue where the
previous one finished.
What you probably need to do is something like this:
xdr_nfs_fh3 (XDR *xdrs, nfs_fh3 *objp)
{
uint32_t size;
if (!xdr_int (xdrs, &size))
if (!xdr_opaque (xdrs, (u_int *)&objp->data.data_len, size))
^ that should be objp->data.data_val of course :-/
return FALSE
return TRUE;
}
That will read the size of the fhandle first, to determine how long the opaque
fhandle is, and use that size to read it.
Cheers,
Niels
But I get no change in behaviour.
Also get these warnings:
xdr-nfs3.c: In function 'xdr_nfs_fh3':

All I get out of gluster is:
[2013-04-08 12:54:32.206312] E [nfs3.c:4741:nfs3svc_fsinfo] 0-nfs-nfsv3:
Error decoding arguments
I've attached abridged packet captures and text explanations of the
packets (thanks to wireshark).
Can someone please look at this and determine if it's gluster's parsing
of the RPC call to blame, or if it's Oracle?
This is the same setup on which I reported the NFS race condition bug.
It does have that patch applied.
