From: Etienne Champetier Date: Wed, 26 Jan 2022 19:33:52 +0000 (-0500) Subject: iptables: rework ip(6)tables-nft dependencies X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b0bd6599e840c443d8ccb8759315e4dd006fd6aa;p=openwrt%2Fstaging%2Fblocktrron.git iptables: rework ip(6)tables-nft dependencies according to iptables-nft man page, "These tools use the libxtables framework extensions and hook to the nf_tables kernel subsystem using the nft_compat module." This means that to work, iptables-nft needs the same modules as iptables legacy except the ip(6)table-{filter,mangle,nat,raw} ip_tables, ip6tables. When those modules are loaded iptables-nft-save output contains "# Warning: iptables-legacy tables present, use iptables-legacy-save to see them" But as long as it's empty it should not be a problem. To have nft properly display the rules created by ip(6)tables-nft we need all iptables targets and matches to be built as extension and not built-in (/usr/lib/iptables/libip(6)t_*.so) When switching a package to iptables-nft, you need to keep the iptables-mod-* dependencies This patch does minimal changes: - remove the direct iptables-nft -> iptables dependency - and more important add nft-compat dependency The rule iptables-nft -A OUTPUT -d 8.8.8.8 -m comment --comment "aaa" -j REJECT becomes table ip filter { chain OUTPUT { type filter hook output priority filter; policy accept; ip daddr 8.8.8.8 # xt_comment counter packets 0 bytes 0 # xt_REJECT } } Signed-off-by: Etienne Champetier --- diff --git a/package/network/utils/iptables/Makefile b/package/network/utils/iptables/Makefile index 2ba30eeca8..853bff39c6 100644 --- a/package/network/utils/iptables/Makefile +++ b/package/network/utils/iptables/Makefile @@ -41,7 +41,7 @@ endef define Package/iptables/Module $(call Package/iptables/Default) - DEPENDS:=iptables $(1) + DEPENDS:=+iptables $(1) endef define Package/iptables @@ -108,7 +108,7 @@ endef define Package/iptables-nft $(call Package/iptables/Default) TITLE:=IP firewall administration tool nft - DEPENDS:=iptables @IPTABLES_NFTABLES +libxtables-nft + DEPENDS:=@IPTABLES_NFTABLES +libxtables-nft +libip4tc +IPV6:libip6tc +kmod-ipt-core +kmod-nft-compat endef define Package/iptables-nft/description @@ -454,7 +454,7 @@ endef define Package/ip6tables-nft $(call Package/iptables/Default) - DEPENDS:=ip6tables @IPTABLES_NFTABLES +libxtables-nft + DEPENDS:=@IPV6 +kmod-ip6tables +iptables-nft TITLE:=IP firewall administration tool nft endef @@ -522,7 +522,7 @@ define Package/libxtables-nft CATEGORY:=Libraries TITLE:=IPv4/IPv6 firewall - shared xtables nft library ABI_VERSION:=12 - DEPENDS:=libxtables + DEPENDS:=+libxtables endef TARGET_CPPFLAGS := \
