If anyone has any objections, please let me know. ------------------ From: Pablo Neira commit e10038a8ec06ac819b7552bb67aaa6d2d6f850c1 upstream. This structure is not exposed to userspace, so fix this by defining struct sk_filter; so we skip the casting in kernelspace. This is safe since userspace has no way to lurk with that internal pointer.
