Hi Cyril,

I'm sorry for the problem, and thank you for the report.

Two questions:
1. Could you double check whether you have the following commit in your tree?

commit 83a1a1a70e87f676fbb6086b26b6ac7f7fdd107d
Author: Soheil Hassas Yeganeh <soheil@...gle.com>
Date:   Wed Nov 30 14:01:08 2016 -0500
    sock: reset sk_err for ICMP packets read from error queue

2. I've also have sent a fix to iputils on
https://github.com/iputils/iputils/pull/75. Would you be kind to try
that pull request as well?

Thanks,
Soheil
