This is a note to let you know that I've just added the patch titled neigh: recompute reachabletime before returning from neigh_periodic_work() to the 3.10-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: neigh-recompute-reachabletime-before-returning-from-neigh_periodic_work.patch and it can be found in the queue-3.10 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 Wed Mar 19 23:28:23 Local time zone must be set--see zic manual page 2014 From: Duan Jiong <duanj.fnst@xxxxxxxxxxxxxx> Date: Thu, 27 Feb 2014 17:14:41 +0800 Subject: neigh: recompute reachabletime before returning from neigh_periodic_work() From: Duan Jiong <duanj.fnst@xxxxxxxxxxxxxx> [ Upstream commit feff9ab2e7fa773b6a3965f77375fe89f7fd85cf ] If the neigh table's entries is less than gc_thresh1, the function will return directly, and the reachabletime will not be recompute, so the reachabletime can be guessed.
