Two Fedora 20s loose their public IPv6 address

Hello!

I have a two F20 boxes configured for IPv6 via RouterAdvertisments (rtadvd on Debian gateway). Both boxes configure correctly on boot. However, after some time (say a few days) they suddenly drop their public IPv6 address - not at the same time as far as I noticed. They still get ICMP6 RA packets (verified with tcpdump), but just ignore them. Some FreeBSDs 10.0B3 on the same network work flawlessly, so it doesn't look like a server-side problem.

Same configuration worked fine with F19 (and yes I know F20 is preliminary edition).

What to look for? Where to report details?

Same here, too. Really bad.

Actually "ip -f inet6 route" shows correct (?) routing, but "ip addr" shows only a link-local. Please fix that soon I don't want to downgrade.

Looks like NetworkManager is the culprit. This is also nice:


[root@localhost jens]# nmcli n

* (process:7885): CRITICAL *: nm_ip6_route_set_prefix: assertion 'prefix > 0' failed

Can confirm. Are your privacy extensions are also broken? See https://bugzilla.redhat.com/show_bug.cgi?id=1047139

Same here. Tested on two boxes. Fedora 20 broke IPv6.
