Sorry for not being very helpful, but I am not really familiar with this code. I saw this crash once but I have not been able to reproduce it. A few other modules seem to use xt_compat_init_offsets(). You think we should handle a 0 size argument, rather than returning -EINVAL, for all of them? How should we handle it, just reset number/cur/compat_tab?
