netfilter: nf_tables: set NLM_F_DUMP_INTR if netlink dumping is stale
An updater may interfer with the dumping of any of the object lists. Fix this by using a per-net generation counter and use the nl_dump_check_consistent() interface so the NLM_F_DUMP_INTR flag is set to notify userspace that it has to restart the dump since an updater has interfered. This patch also replaces the existing consistency checking code in the rule dumping path since it is broken. Basically, the value that the dump callback returns is not propagated to userspace via netlink_dump_start(). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
