This is a note to let you know that I have just added a patch titled net: prevent setting ttl=0 via IP_TTL 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. -Herton ------ From 260d6ea0ca475616c36df877c543133f3470ea10 Mon Sep 17 00:00:00 2001 From: Cong Wang <xiyou.wangcong@gmail.com> Date: Mon, 7 Jan 2013 21:17:00 +0000 Subject: [PATCH] net: prevent setting ttl=0 via IP_TTL commit c9be4a5c49cf51cc70a993f004c5bb30067a65ce upstream. A regression is introduced by the following commit: commit 4d52cfbef6266092d535237ba5a4b981458ab171 Author: Eric Dumazet <eric.dumazet@gmail.com> Date: Tue Jun 2 00:42:16 2009 -0700 net: ipv4/ip_sockglue.c cleanups Pure cleanups but it is not a pure cleanup... - if (val != -1 && (val < 1 || val>255)) + if (val != -1 && (val < 0 || val > 255)) Since there is no reason provided to allow ttl=0, change it back.
