From 36b05bbed34c8f4192ea04d17a030fc78e6e5c4f Mon Sep 17 00:00:00 2001 From: Steven Barth Date: Thu, 2 Oct 2014 19:37:36 +0000 Subject: [PATCH] IPIP: IP in IP package support The package supports IP in IP by registering the ipip protocol handler Following options are configurable -peeraddr (IPv4 remote address) -ipaddr (IPv4 local address) -ttl (time to live of encapsulating packet) -tos (type of service of encapsulating packet either inherit (outer header inherits the value of the inner header) or hex value) -df (don't fragment flag of encapsulating packet) -mtu (IPIP tunnel mtu) -tunlink (bind tunnel to this interface) -zone (firewall zone to which the IPIP tunnel will be added) Signed-off-by: Hans Dedecker SVN-Revision: 42746 --- package/network/config/ipip/Makefile | 39 +++++++++++ package/network/config/ipip/files/ipip.sh | 80 +++++++++++++++++++++++ 2 files changed, 119 insertions(+) create mode 100644 package/network/config/ipip/Makefile create mode 100755 package/network/config/ipip/files/ipip.sh diff --git a/package/network/config/ipip/Makefile b/package/network/config/ipip/Makefile new file mode 100644 index 0000000000..98f7b78d5c --- /dev/null +++ b/package/network/config/ipip/Makefile @@ -0,0 +1,39 @@ +# +# Copyright (C) 2014 OpenWrt.org +# +# This is free software, licensed under the GNU General Public License v2. +# See /LICENSE for more information. +# + +include $(TOPDIR)/rules.mk + +PKG_NAME:=ipip +PKG_VERSION:=1 +PKG_RELEASE:=1 + +include $(INCLUDE_DIR)/package.mk + +define Package/ipip + SECTION:=net + CATEGORY:=Network + MAINTAINER:=Hans Dedecker + TITLE:=IP in IP Tunnel config support + DEPENDS:= +kmod-ipip +endef + +define Package/ipip/description + IP in IP Tunnel config support in /etc/config/network. +endef + +define Build/Compile +endef + +define Build/Configure +endef + +define Package/ipip/install + $(INSTALL_DIR) $(1)/lib/netifd/proto + $(INSTALL_BIN) ./files/ipip.sh $(1)/lib/netifd/proto/ipip.sh +endef + +$(eval $(call BuildPackage,ipip)) diff --git a/package/network/config/ipip/files/ipip.sh b/package/network/config/ipip/files/ipip.sh new file mode 100755 index 0000000000..51c503f895 --- /dev/null +++ b/package/network/config/ipip/files/ipip.sh @@ -0,0 +1,80 @@ +#!/bin/sh + +[ -n "$INCLUDE_ONLY" ] || { + . /lib/functions.sh + . /lib/functions/network.sh + . ../netifd-proto.sh + init_proto "$@" +} + +proto_ipip_setup() { + local cfg="$1" + + local df ipaddr peeraddr tunlink ttl tos zone mtu + json_get_vars df ipaddr peeraddr tunlink ttl tos zone mtu + + [ -z "$peeraddr" ] && { + proto_notify_error "$cfg" "MISSING_ADDRESS" + proto_block_restart "$cfg" + return + } + + ( proto_add_host_dependency "$cfg" "$peeraddr" "$tunlink" ) + + [ -z "$ipaddr" ] && { + local wanif="$tunlink" + if [ -z $wanif ] && ! network_find_wan wanif; then + proto_notify_error "$cfg" "NO_WAN_LINK" + return + fi + + if ! network_get_ipaddr ipaddr "$wanif"; then + proto_notify_error "$cfg" "NO_WAN_LINK" + return + fi + } + + [ -z "$zone" ] && zone="wan" + + proto_init_update "ipip-$cfg" 1 + + proto_add_tunnel + json_add_string mode "ipip" + json_add_int mtu "${mtu:-1280}" + json_add_int ttl "${ttl:-64}" + [ -n "$tos" ] && json_add_string tos "$tos" + json_add_string local "$ipaddr" + json_add_string remote "$peeraddr" + [ -n "$tunlink" ] && json_add_string link "$tunlink" + json_add_boolean df "${df:-1}" + + proto_close_tunnel + + proto_add_data + [ -n "$zone" ] && json_add_string zone "$zone" + proto_close_data + + proto_send_update "$cfg" +} + +proto_ipip_teardown() { + local cfg="$1" +} + +proto_ipip_init_config() { + no_device=1 + available=1 + + proto_config_add_int "mtu" + proto_config_add_int "ttl" + proto_config_add_string "tos" + proto_config_add_string "tunlink" + proto_config_add_string "zone" + proto_config_add_string "ipaddr" + proto_config_add_string "peeraddr" + proto_config_add_boolean "df" +} + +[ -n "$INCLUDE_ONLY" ] || { + add_protocol ipip +}
