Description Wolfgang Rosenauer 2015-07-11 19:32:03 UTC

This is basically a copy of a Gnome/NetworkManager bug which affects openSUSE 13.2 and hit me in real life.

In IPv6 router advertisements it might be possible that a hop limit of 0 is specified. According to the specification this means "undefined" which should result in the client using his own default setting.
NetworkManager in 13.2 uses the value 0 which breaks IPv6 connectivity completely.

Comment 1 Wolfgang Rosenauer 2015-07-11 19:33:46 UTC

I have prepared an update for 13.2. Can I submit?

(Please note that NetworkManager on 13.1 seems to be unaffected. At least I couldn't find any reference to hop_limit in the code.)

Wolfgang, feel free to open a maintenancerequest with the updated package. If the maintainer agrees with the fix, we'll start an update.

Thanks in advance.
