Florian Westphal b54be44540 netfilter: x_tables: fix compat match/target pad out-of-bound write ... commit b29c457a6511435960115c0f548c4360d5f4801d upstream. xt_compat_match/target_from_user doesn't check that zeroing the area to start of next rule won't write past end of allocated ruleset blob. Remove this code and zero the entire blob beforehand.
