3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Pablo Neira Ayuso <[email protected]> commit 62924af247e95de7041a6d6f2d06cdd05152e2dc upstream. Relax the checking that was introduced in 97840cb ("netfilter: nfnetlink: fix insufficient validation in nfnetlink_bind") when the subscription bitmask is used. Existing userspace code code may request to listen to all of the existing netlink groups by setting an all to one subscription group bitmask. Netlink already validates subscription via setsockopt() for us.
