From: Yousong Zhou Date: Fri, 18 Jan 2019 06:42:21 +0000 (+0000) Subject: shadowsocks-libev: ss-rules: add ipv6 support X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5fd46871643f0dcf9790c1c9136ca28d388ed307;p=feed%2Fpackages.git shadowsocks-libev: ss-rules: add ipv6 support It will require support from ip6tables-mod-nat. The added functionality will be skipped otherwise. For $o_dst_bypass6_, include only address blocks in link [1] whose "Globally Reachable" field are explicitly "False" Closes openwrt/packages#7508 [1] IANA IPv6 Special-Purpose Address Registry, https://www.iana.org/assignments/iana-ipv6-special-registry/iana-ipv6-special-registry.xhtml Signed-off-by: Yousong Zhou --- diff --git a/net/shadowsocks-libev/Makefile b/net/shadowsocks-libev/Makefile index 0b2df0e99f..81731283f0 100644 --- a/net/shadowsocks-libev/Makefile +++ b/net/shadowsocks-libev/Makefile @@ -14,7 +14,7 @@ include $(TOPDIR)/rules.mk # PKG_NAME:=shadowsocks-libev PKG_VERSION:=3.2.3 -PKG_RELEASE:=1 +PKG_RELEASE:=2 PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz PKG_SOURCE_URL:=https://github.com/shadowsocks/shadowsocks-libev/releases/download/v$(PKG_VERSION) diff --git a/net/shadowsocks-libev/files/shadowsocks-libev.init b/net/shadowsocks-libev/files/shadowsocks-libev.init index 22d825d0b1..23cb873cc6 100644 --- a/net/shadowsocks-libev/files/shadowsocks-libev.init +++ b/net/shadowsocks-libev/files/shadowsocks-libev.init @@ -157,7 +157,12 @@ ss_rules() { ss_redir_servers="$(echo "$ss_redir_servers" | tr ' ' '\n' | sort -u)" [ "$dst_forward_recentrst" = 0 ] || args="$args --dst-forward-recentrst" - "$bin" \ + ss_rules_call + ss_rules_call -6 +} + +ss_rules_call() { + "$bin" "$@" \ -s "$ss_redir_servers" \ -l "$local_port_tcp" \ -L "$local_port_udp" \ @@ -174,7 +179,7 @@ ss_rules() { --ifnames "$ifnames" \ --ipt-extra "$ipt_args" \ $args \ - || "$bin" -f + || "$bin" "$@" -f } start_service() { @@ -280,13 +285,13 @@ validate_ss_rules_section() { 'disabled:bool:0' \ 'redir_tcp:uci("shadowsocks-libev", "@ss_redir")' \ 'redir_udp:uci("shadowsocks-libev", "@ss_redir")' \ - 'src_ips_bypass:or(ip4addr,cidr4)' \ - 'src_ips_forward:or(ip4addr,cidr4)' \ - 'src_ips_checkdst:or(ip4addr,cidr4)' \ + 'src_ips_bypass:or(ipaddr,cidr)' \ + 'src_ips_forward:or(ipaddr,cidr)' \ + 'src_ips_checkdst:or(ipaddr,cidr)' \ 'dst_ips_bypass_file:file' \ - 'dst_ips_bypass:or(ip4addr,cidr4)' \ + 'dst_ips_bypass:or(ipaddr,cidr)' \ 'dst_ips_forward_file:file' \ - 'dst_ips_forward:or(ip4addr,cidr4)' \ + 'dst_ips_forward:or(ipaddr,cidr)' \ 'src_default:or("bypass", "forward", "checkdst"):checkdst' \ 'dst_default:or("bypass", "forward"):bypass' \ 'local_default:or("bypass", "forward", "checkdst"):bypass' \ diff --git a/net/shadowsocks-libev/files/ss-rules b/net/shadowsocks-libev/files/ss-rules index b0a30606e1..3d7bcdce30 100755 --- a/net/shadowsocks-libev/files/ss-rules +++ b/net/shadowsocks-libev/files/ss-rules @@ -8,10 +8,24 @@ # See /LICENSE for more information. # +__errmsg() { + echo "ss-rules: $*" >&2 +} + +if [ "$1" = "-6" ]; then + if ! ip6tables -t nat -L -n >/dev/null; then + __errmsg "Skipping ipv6.
