This issue may be resolved by providing a newer version of networkmanager (= 0.9.10.2) In this version a patch was introduced to mitigate CVE-2015-2922 (don't allow setting the HL smaller than it was before) This patch also makes sure a HL 10 does not get set.

[Touch-packages] [Bug 1450066] Re: IPv6 hop limit set to 0
This bug is due to a failure in handling router advertisments. According to RFC 4861 (page 20) a _Cur Hop Limit_ set to 0 means, that the Hop Limit is unspecified. Ubuntu 15.04 takes this literally and sets HL to 0. Fortunately my router provided the option to set this field to a manual value, altough i suppose this is not the case for most routers. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1450066 Title: IPv6 hop limit set to 0 Status in network-manager package in Ubuntu: Triaged Status in network-manager source package in Vivid: Triaged Bug description: On upgrading from Ubuntu 14.10 to 15.04 I found that my IPv6 networking no longer worked.

I hate to nag, but this should really be a high-priority. IPv6 is completely unusable on majority of networks, since no routers that I know actually broadcast a hop limit.

Please please cherry pick the patch from gnome bugzilla and apply it to vivid http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=6a79acb0 This bug makes most IPv6 connections unusable without manual intervention (either setting the hop limit on each router that does not set that in RAs - most!) or manually changing the limit after every connection. I wouldn't say it's critical (most of us still have IPv4 access too :), but it's definitely a High importance bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1450066 Title: IPv6 hop limit set to 0 Status in network-manager package in Ubuntu: Confirmed Bug description: On upgrading from Ubuntu 14.10 to 15.04 I found that my IPv6 networking no longer worked.
