Hello Mathieu, or anyone else affected, Accepted network-manager into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
** Also affects: network-manager (Ubuntu Precise) Importance: Undecided Status: New ** Changed in: network-manager (Ubuntu Precise) Status: New => Fix Committed ** Tags added: verification-needed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/990011 Title: use_tempaddr is *still* not set properly for default eth0 connections Status in “network-manager” package in Ubuntu: In Progress Status in “network-manager” source package in Precise: Fix Committed Bug description: [Impact] Only affects IPv6 connections, but we established that the default should be to maintain our users' privacy on IPv6 connections; we want all IPv6 external connections to be established using temporary, dynamic addresses. [Development Fix] Very minor patch to threat an unknown value (-1) as (2), aka, enabling and preferring privacy extensions. Patch is attached. [Stable Fix] See "Development fix". [Test case] Connect a wire to your system. With NetworkManager running, the value returned by 'sysctl net.ipv6.conf.eth0.use_tempaddr' should be 2 at all times unless configured otherwise (though the default is set to 2 by default). Without the patch, the value is reset to 0 when NetworkManager is running, and correctly set to 2 when NetworkManager is stopped (since it reverts the value to the value when NM started). [Regression Potential] Low, impact may be failing connections in case of issues with the privacy extensions system in the Linux kernel. ---- The use_tempaddr sysctl defaults to 0 in NetworkManager if it's not set elsewhere, such as it is the case for the default NM-created, automatic wired connection. That connection is never "completed" (because it's internal magic), and nm_backend_ipv6_use_tempaddr() doesn't have a chance of returning a valid system-wide default value since the function it calls, nm_generic_ipv6_use_tempaddr() only checks in /etc/sysctl.conf and /lib/sysctl.d/sysctl.conf for a system default value. (Regardless, this wouldn't work since we generate a setting based on a number of files in /etc/sysctl.d) Change the behavior slightly to default to a string of -1 as a default value in nm-system.c; then make sure that if that value is never changed by the result of nm_backend_ipv6_use_tempaddr(), we just don't touch that sysctl at all.
