netfilter: ipt_CLUSTERIP: fix out-of-bounds accesses in clusterip_tg_check()
commit 1a38956cce5eabd7b74f94bab70265e4df83165e upstream.
Commit 136e92bbec0a switched local_nodes from an array to a bitmask
but did not add proper bounds checks. As the result
clusterip_config_init_nodelist() can both over-read
ipt_clusterip_tgt_info.local_nodes and over-write
clusterip_config.local_nodes.
Add bounds checks for both.
Fixes: 136e92bbec0a ("[NETFILTER] CLUSTERIP: use a bitmap to store node responsibility data")
