Description Neil Rickert 2015-04-23 22:40:04 UTC

Build Identifier: 

I'm using "wicked".  The IPv6 privacy extensions have been working well in 13.2 and in Tumbleweed until recently.  This is where I get a permanent IPv6 address and a temporary (randomized) address.

In the last week or so, that seems to have stopped, and I am only getting a permanent address.

The file "/usr/lib/sysctl.d/50-default.conf" contains the line:
net.ipv6.conf.default.use_tempaddr = 2

so I believe that the default should be to use a temporary address.

As a work-around, I have created "/etc/sysctl.d/60-eno1.conf" containing:
net.ipv6.conf.eno1.use_tempaddr = 2

That seems to give me a temp address again.  But I don't think that should be needed.  (The interface name is "eno1".

An additional note:  I have three installs of Tumbleweed with this problem, though I have only tried the workaround on one.

I have one addition install, where the privacy extensions are working just fine.  I'm not sure of the difference, except that there is less software installed there.  I installed minimal X, Plasma 5, lightdm and a few other minor programs.  On the systems with the problem, I originally installed KDE, Gnome, XFCE, LXDE, and on one of them I later installed Plasma5.  So perhaps some of that extra software is breaking the privacy extensions in its startup file.

Reproducible: Always

Hi Ludwig, would you please help to have a look at this? I'm not quite sure whether it is right to assign it to you, please feel free to reassign whenever necessary, thank you!

The patch in https://github.com/openSUSE/wicked/pull/593 should fix it
to read also sysctl's from /usr/lib/sysctl.d.

I've applied it to testing, that is test RPMs will be available at:
