If read() syscall requests unexpected number of bytes from "dimm" binary attribute file, return EINVAL instead of EPERM. At the same time pin down sysfs file size to the fixed sizeof(struct netxen_dimm_cfg), which allows to exploit some missing sanity checks from kernfs (file boundary checks vs offset etc.) Signed-off-by:
