[Bug 849994] Re: FFE: add NetworkManager DUID support

 

I'm happy with this feature freeze exception, given stgraber's advance
testing work and the upstream discussion so far.  In fact, I consider
the current state buggy, so it's not entirely clear to me that this is a
feature, but whatever. :-)

Title:
  FFE: add NetworkManager DUID support

Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  I wrote a patch to handle DHCPv6 DUIDs properly in NetworkManager;
  ideally this should be shipped with NM in Oneiric to properly support
  multiple interfaces getting consistently the same DUID across multiple
  DHCP requests; which should allow multiple interfaces to get the same
  IPv6 address if they are on the same network.

  The patch is relatively simple and watches the DUID already provided
  by dhclient if it's available and attempts to make sure it is recorded
  in the future lease files when necessary. If the DUID isn't present
  anywhere, it will be generated as a DUID-LLT, and the values from
  dhclient always takes precedence.

  An experimental package has been built in my PPA for testing. Testing
  was done and completed successfully across different permutations of
  DHCPv6, DHCP, SLAAC, etc. with no adverse effects.
