push route-ipv6 without effect #320

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Configure ipv6 tunneling
2. To route through VPN connection by default include: push "route-ipv6 
2000::/3"
3. Try to ping6 to e.g. google

What is the expected output? What do you see instead?

Want to see ping response, get network not reachable.

What mobile phone are you using?

i9100

Which Android Version and stock ROM or aftermarket like cyanogenmod?

cyanogenmod cm-11-20141115-SNAPSHOT

Please provide any additional information below.

Actually, everything works except the missing route. When I connect to the 
phone using adb and issue:

ip -6 r add 2000::/3 dev tun0

then everything works. So the only thing that doesn't work is adding the route. 
It *is* pushed. From the log:

2015-01-20 20:34:50 MANAGEMENT: >STATE:1421782490,ADD_ROUTES,,,
2015-01-20 20:34:50 MANAGEMENT: CMD 'needok 'ROUTE' ok'
2015-01-20 20:34:50 MANAGEMENT: CMD 'needok 'ROUTE' ok'
2015-01-20 20:34:50 MANAGEMENT: CMD 'needok 'ROUTE' ok'
2015-01-20 20:34:50 add_route_ipv6(::/0 -> fd43:f675:e811::1 metric -1) dev 
(null)
2015-01-20 20:34:50 MANAGEMENT: CMD 'needok 'ROUTE6' ok'
2015-01-20 20:34:50 add_route_ipv6(2000::/3 -> fd43:f675:e811::1 metric -1) dev 
(null)
2015-01-20 20:34:50 MANAGEMENT: CMD 'needok 'ROUTE6' ok'

But obviously the received push isn't processed.

That is a known bug in Android 4.4. IPv6 over VPN does not work.

OK. I'd only like to emphasize that IPv6 over VPN DOES work without problems. 
The only single thing that doesn't work is the handling of push-routeipv6.

okay. Can you paste the lines with the VPN Konfiguration? The ones with routes 
installed? I have not yet seen a working IPv6 VPN on Android 4.4.x. Maybe CM 
has fixed something there.

No there should be somehting in the log. Like VPNService routes installed.
