Hello!

I spotted your patch[1] to prevent ipv6 preferred lifetime wraparound.
It looks to me like you fixed the preferred lifetime, but did not touch
the valid lifetime. According to a debian bugreport[2] it seems both of
them like to wrap around. Shouldn't the "valid -= tval;", visible in
your patch context, also be conditional similar to your change for
"preferred -= tval;" ?


Regards,
Andreas Henriksson
