Okay, then I misunderstood your earlier comment. And guess it is not backported to latest 4.19 as that also fails. Just to sanity check, I'll test mainline to satisfy my curiosity. Thank you all for your time and replies! On Mon, Mar 11, 2019 at 10:20 PM Eric Dumazet wrote: > > > > On 03/11/2019

Thank you all for the reply. The problem started with 4.9.133, and persists to latest 4.9 today. I will work on the bisect approach to find the bad commit(s). It will take a few days. I will reply back when I have more info. On Wed, Mar 6, 2019 at 3:34 PM Eric Dumazet wrote: > > > > On 03/06/2019

We are using the TAHI Self-test tools from IPv6 Ready Logo Program: https://www.ipv6ready.org/?page=documents&tag=ipv6-core-protocols The test passed up to 4.9.133, then fails ever since. The are about 20 failing test cases regarding IPv6 fragments, where the kernel is issuing an ICMPv6 parameter
