From shemminger@vyatta.com Tue Jul 27 16:56:59 2010 From: Stephen Hemminger Date: Mon, 24 May 2010 11:31:18 -0700 Subject: IPv6: keep route for tentative address To: Emil S Tantilov Cc: NetDev , stable@kernel.org, Greg KH , "David S. Miller" , "Tantilov, Emil S" Message-ID: <20100524113118.47cc9852@nehalam> From: Stephen Hemminger (cherry picked from commit 93fa159abe50d3c55c7f83622d3f5c09b6e06f4b) Recent changes preserve IPv6 address when link goes down (good). But would cause address to point to dead dst entry (bad). The simplest fix is to just not delete route if address is being held for later use. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
