There is a problem when setting the lifetime of an IPv6 address.
When I set preferred_lft to a value not zero or infinity, while valid_lft

is infinity(0xffffffff)

quoted

preferred lifetime is set to forever and does not update.
Therefore preferred lifetime never becomes deprecated.

I think valid lifetime and preferred lifetime should be set

independently,

even if valid lifetime is infinity, preferred lifetime must expire

correctly (meaning it must eventually become deprecated)

I made a patch for 3.12 stable to solve the problem.

This indeed could be improved. Thanks for the patch. But you should

base

it on net-next so it can be applied and please clean up the warnings
and errors if you run the patch through ./scripts/checkpatch --strict.

Thank you,

  Hannes

I made a patch based on net-next and emailed ML using git send-email last

night.
