This is a note to let you know that I've just added the patch titled ipv6: don't count addrconf generated routes against gc limit to the 3.12-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: ipv6-don-t-count-addrconf-generated-routes-against-gc-limit.patch and it can be found in the queue-3.12 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Mon Jan 13 09:44:41 PST 2014 From: Hannes Frederic Sowa <hannes@xxxxxxxxxxxxxxxxxxx> Date: Sat, 7 Dec 2013 03:33:45 +0100 Subject: ipv6: don't count addrconf generated routes against gc limit From: Hannes Frederic Sowa <hannes@xxxxxxxxxxxxxxxxxxx> [ Upstream commit a3300ef4bbb1f1e33ff0400e1e6cf7733d988f4f ] Brett Ciphery reported that new ipv6 addresses failed to get installed because the addrconf generated dsts where counted against the dst gc limit. We don't need to count those routes like we currently don't count administratively added routes. Because the max_addresses check enforces a limit on unbounded address generation first in case someone plays with router advertisments, we are still safe here.
