extensions: libipt_DNAT/SNAT: fix "OOM" when do translation to nft
When I want to translate SNAT target to nft rule, an error message was printed out: # iptables-translate -A POSTROUTING -j SNAT --to-source 1.1.1.1 iptables-translate v1.6.0: OOM Because ipt_natinfo{} started with a xt_entry_target{}, so when we get the ipt_natinfo pointer, we should use the target itself, not its data pointer. Yes, it is a little tricky and it's different with other targets. Fixes: 7a0992da44cf ("src: introduce struct xt_xlate_{mt,tg}_params") Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
