[ Upstream commit c9be4a5c49cf51cc70a993f004c5bb30067a65ce ]
A regression is introduced by the following commit:
commit 4d52cfbef6266092d535237ba5a4b981458ab171
Author: Eric Dumazet <eric.dumazet@gmail.com>

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.
