[Pkg-utopia-maintainers] Bug#668462: network-manager: Wrong default for IPv6 Privacy Extensions

[Juerd Waalboer]

Package: network-manager
Version: 0.9.4.0-3
Severity: important
Tags: ipv6

Dear Maintainer,

One of the changes in a recent release was that "IPv6 Privacy Extensions are
now enabled by default for new connections". While this is true, and a very
good idea, it has introduced an annoying regression for existing connections
carried over from a previous version, resulting in disabled Privacy Extensions
where they were previously enabled.

It appears that when ip6-privacy is not defined, it defaults to 0. I believe
that it should default to nothing at all and leave the sysctl value at whatever
value was set without the help of NetworkManager. Users who had enabled IPv6
Privacy Extensions will probably have done so by adding a manual sysctl for
net.ipv6.conf.*.use_tempaddr; the current NetworkManager overrides this value,
possibly disabling previously perfectly functioning IPv6 Privacy Extensions.

The problem is made worse by the current Gnome 3 thing not having any GUI
elements to change this setting, or to delete a connection profile. Or at least
I couldn't find them. Removing the connection profile file helps (the new one
will be created with ip6-privacy=2 in it), as does adding ip6-privacy=2
manually.


Best regards,

Juerd
