[PATCH 3/7] netfilter: nft_compat: fix hook validation for non-base chains

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2014-10-20 08:09:17
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

Set hook_mask to zero for non-base chains, otherwise people may hit
bogus errors from the xt_check_target() and xt_check_match() when
validating the uninitialized hook_mask.
