Well that was easy, now that you identified rc6 as working. I'll be willing to bet this is the fix:
commit b194c1f1dbd5f2671e49e0ac801b1b78dc7de93b Author: Jiri Pirko <j...@resnulli.us> Date: Fri Feb 21 14:52:57 2014 +0100 neigh: fix setting of default gc_* values This patch fixes bug introduced by: commit 1d4c8c29841b9991cdf3c7cc4ba7f96a94f104ca "neigh: restore old behaviour of default parms values" The thing is that in neigh_sysctl_register, extra1 and extra2 which were previously set for NEIGH_VAR_GC_* are overwritten. That leads to nonsense int limits for gc_* variables. So fix this by not touching extra* fields for gc_* variables. Signed-off-by: Jiri Pirko <j...@resnulli.us> Signed-off-by: David S. Miller <da...@davemloft.net> I'll build a Trusty test kernel with a pick of this commit and post a link to it shortly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634892 Title: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
