smack with nfs #138

When I enable the smack lsm and try to mount an nfs share I get mount.nfs: Protocol error as soon as I disable smack it mounts without issues, I have nfs-utils 2.6.2 and smackctl 1.3.1, I set smack logging to 3 but the only things in dmesg are access granted and no errors.

What kernel version are you using? When labeled NFS support was added to the kernel it was only validated using SELinux. Check the values for CONFIG_NFS_V4_SECURITY_LABEL and CONFIG_NFSD_V4_SECURITY_LABEL. If they are set to "y" you may have better results turning them off.
