extensions: libxt_iprange: handle the invert flag properly in translation
If we specify the invert flag, we should put "!=" after "ip saddr/daddr",
so the current translation is wrong:
# iptables-translate -A OUTPUT -m iprange ! --dst-range 1.1.1.1-1.1.1.2
nft add rule ip filter OUTPUT != ip daddr 1.1.1.1-1.1.1.2 counter
# ip6tables-translate -A OUTPUT -m iprange ! --src-range 2003::1-2003::3
nft add rule ip6 filter OUTPUT != ip6 saddr 2003::1-2003::3 counter
Apply this patch:
# iptables-translate -A OUTPUT -m iprange ! --dst-range 1.1.1.1-1.1.1.2
nft add rule ip filter OUTPUT ip daddr != 1.1.1.1-1.1.1.2 counter
# ip6tables-translate -A OUTPUT -m iprange ! --src-range 2003::1-2003::3
nft add rule ip6 filter OUTPUT ip6 saddr != 2003::1-2003::3 counter
