This is a note to let you know that I have just added a patch titled net: rate-limit warn-bad-offload splats. to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From a6f1fa3ce26418b261ad49aa0eb8d9f501feb207 Mon Sep 17 00:00:00 2001 From: Ben Greear <greearb@candelatech.com> Date: Fri, 19 Apr 2013 10:45:52 +0000 Subject: [PATCH] net: rate-limit warn-bad-offload splats. commit c846ad9b880ece01bb4d8d07ba917734edf0324f upstream. If one does do something unfortunate and allow a bad offload bug into the kernel, this the skb_warn_bad_offload can effectively live-lock the system, filling the logs with the same error over and over. Add rate limitation to this so that box remains otherwise functional in this case. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: David S.
