This triggers\nthe WARN_ON() at nf_nat_setup_info() and if panic_on_warn isn't set,\nthen IPS_SRC_NAT_DONE is set without adding nat_bysource and conntrack\ncleanup tries to unlink an uninitialized hlist node.\n\nFix this by checking that NAT manipulation type is correct before\ncalling nf_nat_setup_info(). In addition, if the WARN_ON is hit, return\nNF_DROP instead of continuing with the processing to avoid similar\nsituations in the future."
