I'd say this bug report is invalid, and not kernel related at all, and simply utopic probably had newer iproute2 userspace package with proper support for these flags.
See: https://patchwork.ozlabs.org/patch/519505/ Specifically address that is derived from MAC should be marked as mngtmpaddr, as this is then the template for privacy extensions if enabled. When privacy extensions are enabled, the MAC based address would also have noprefixroute flag, and additional address fd:: address would be generated from mngtmpaddr template and itself marked as temporary. The output you show looks correct when stateless auto-configuration is used, with privacy extensions not enabled. ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1380614 Title: IPv6 address marked as 'mngtmpaddr' under utopic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1380614/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
