From c6fbfac2e61c9a8617f64b93e8c990b8d864bce5 Mon Sep 17 00:00:00 2001 From: Benoit Boissinot Date: Wed, 2 Apr 2008 00:00:58 -0700 Subject: [PATCH] IPv6: only update the lifetime of the relevant temporary address When receiving a prefix information from a routeur, only update the lifetimes of the temporary address associated with that prefix. Otherwise if one deprecated prefix is advertized, all your temporary addresses will become deprecated. Signed-off-by: Benoit Boissinot Acked-by: YOSHIFUJI Hideaki Signed-off-by: David S.
