Subject: [PATCH net 0/3] vti4, ip_tunnel: Fixes for MTU assignment and validation
Date: Thu, 15 Mar 2018 17:16:26 +0100 [thread overview]
Message-ID: <cover.1521068627.git.sbrivio@redhat.com> (raw)
Patch 1/3 re-introduces a fix to ensure that default MTU on new
link is not lowered unnecessarily because of double counting of
headers. This fix was originally introduced in 2014 and got lost
in a merge commit shortly afterwards.
Patches 2/3 and 3/3 ensure that MTU passed from userspace on link
creation is taken into account and also properly validated.
Stefano Brivio (3):
vti4: Don't count header length twice on tunnel setup
ip_tunnel: Clamp MTU to bounds on new link
vti4: Don't override MTU passed on link creation via IFLA_MTU
