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

Title:
  IPv6 address marked as 'mngtmpaddr' under utopic

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Utopic amd64 cloud image, privacy extensions disabled:

  2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
      link/ether fa:16:3e:45:cc:d4 brd ff:ff:ff:ff:ff:ff
      inet 10.5.17.8/16 brd 10.5.255.255 scope global eth0
         valid_lft forever preferred_lft forever
      inet6 fd31:d8a7:86e5:5721:f816:3eff:fe45:ccd4/64 scope global mngtmpaddr dynamic 
         valid_lft 86392sec preferred_lft 14392sec
      inet6 fe80::f816:3eff:fe45:ccd4/64 scope link 
         valid_lft forever preferred_lft forever

  The address is correctly generated from the MAC of the network
  adapter, however the entry is marked mngtmpaddr which I think is
  incorrect.  Envionment is SLAAC via radvd - equivalent entry from a
  trusty machine deployed in the same environment:

  2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
      link/ether fa:16:3e:41:84:29 brd ff:ff:ff:ff:ff:ff
      inet 10.5.16.240/16 brd 10.5.255.255 scope global eth0
