====== System info ======

  • Device problem occurs on
    • x86-64 based router
  • Software versions of OpenWrt/LEDE release, packages, etc.
    • OpenWrt 21.02.1

====== ISP connectivity options ======
My ISP (Orange Polska) provides two options for network connectivity:

  • IPv4
  • IPv6 with DS-Lite

My WAN interface is called "Orange".

===== IPv4 =====

IPv4 setup works fine. My router uses PPPoE to authenticate, setup all routes etc and things "just works".

===== IPv6 =====

IPv6 is more problematic. I can setup IPv6 only network (including LAN clients). But to get IPv4 connectivity I need to setup DS-Lite.

Installed 'ds-lite' package. Used tcpdump to get AFTR address from DHCPv6 packets. Reconfigured "Orange_6" and "Orange_DS_lite":

config interface 'Orange'
option proto 'pppoe'
option device 'eth0.35'
option username 'bez_ochrony-REDACTED@neostrada.pl/ipv6'
option password 'REDACTED'
option ipv6 'auto'
option ip6assign '64'

config interface 'Orange_6'
option proto 'dhcpv6'
option device '@Orange'
option iface_dslite 'Orange_DS_lite'
option reqaddress 'try'
option reqprefix 'auto'
option reqopts '64'

config interface 'Orange_DS_lite'
option proto 'dslite'
option peeraddr 'szcz01f.cgn.tpnet.pl'
option ip6addr '2a01:ZZZZ:YYYY:XXXX::1'
option encaplimit 'ignore'

I can see (from debug output added in /lib/netifd/proto/dslite.sh and /lib/netifd/netifd-proto.sh scripts) that it tries to configure DS-Lite link:

Sat Jan 1 13:11:14 2022 daemon.notice netifd: Orange_DS_lite (13810): dslite.sh: ip6addr: 2a01:ZZZZ:YYYY:XXXX::1 Sat Jan 1 13:11:14 2022 daemon.notice netifd: Orange_DS_lite (13810): dslite.sh: peeraddr: 2a01:1000:0:1::9114 Sat Jan 1 13:11:14 2022 daemon.notice netifd: Orange_DS_lite (13810): _proto_notify(): iface=Orange_DS_lite opts= Sat Jan 1 13:11:14 2022 daemon.notice netifd: Orange_DS_lite (13810): _proto_notify(): json_dump={ "action": 0, "ifname": "ds-Orange_DS_lite", "link-up": true, "tunnel": { "mode": "ipip6", "mtu": 1280, "ttl": 64, "local": "2a01:ZZZZ:YYYY:XXXX::1", "remote": "2a01:1000:0:1::9114", "data": { "encaplimit": "ignore" } }, "data": { "firewall": [ { "type": "nat", "target": "ACCEPT" } ] }, "keep": false, "ipaddr": [ { "ipaddr": "192.0.0.2", "ptp": "192.0.0.1" } ], "routes": [ { "target": "0.0.0.0", "netmask": "0" } ], "interface": "Orange_DS_lite" } Sat Jan 1 13:11:14 2022 daemon.notice netifd: Orange_DS_lite (13810): Command failed: Invalid argument

And then it loops and floods log with repeated failures.

What is wrong?

Installed 'ip-full' to have 'ip -6 tunnel' working.

So this fixed the issue?
Or did you mean to note that the (required?) full flavor of the ip tool is present?

It does not fixed the issue.

I installed it when tried to skip dslite.sh script and setup such tunnel by hand. "busybox ip" lacks tunnel subcommand.

So left comment in case it mattered.

Some debugs later:

Wed Jan 12 12:53:40 2022 daemon.notice netifd: Orange_DS_lite (8544): _proto_notify(): iface=Orange_DS_lite opts=
Wed Jan 12 12:53:40 2022 daemon.notice netifd: Orange_DS_lite (8544): _proto_notify(): { "action": 0, "ifname": "ds-Orange_DS_lite", "link-up": true, "tunnel": { "mode": "ipip6", "mtu": 1280, "ttl": 64, "local": "2a01:ZZZZ:YYYY:XXXX::1", "remote": "2a01:1000:0:1::9114", "data": { "encaplimit": "ignore" } }, "data": { "firewall": [ { "type": "nat", "target": "ACCEPT" } ] }, "keep": false, "ipaddr": [ { "ipaddr": "192.0.0.2", "ptp": "192.0.0.1" } ], "routes": [ { "target": "0.0.0.0", "netmask": "0" } ], "interface": "Orange_DS_lite" }
Wed Jan 12 12:53:40 2022 daemon.notice netifd: Orange_DS_lite (8544): Command failed: Invalid argument

That's _proto_notify() from /lib/netifd/netifd-proto.sh:

_proto_notify() { local interface="$1" local options="$2" echo "_proto_notify(): iface=$1 opts=$2" json_add_string "interface" "$interface" echo "_proto_notify(): $(json_dump)" ubus $options call network.interface notify_proto "$(json_dump)" }

I added echo lines to find out what it gets.

Same "command failed" with and without "ip-full" package installed.
