Variable-length data?

I have written a simple filter for matching multiple network masks in a
list.  From what I can see, the actual netfilter data has to be constant
sized.  Is this true, or is there an easy way to have a non-fixed size
list of addresses (for example)?  It seems rather wasteful to allocate a
large array when only a small one is needed.
