Title:
regression: IPv6 PMTU discovery fails with source-specific routing
Status in linux package in Ubuntu:
Incomplete
Bug description:
IPv6 PMTU discovery fails when using source-specific routing on Ubuntu
18.04.
I have attached a test case called pmtu-sads.sh which is based on
tools/testing/selftests/net/pmtu.sh in the linux source.
I have verified that the test fails on:
Ubuntu 18.04 with 4.15.0-30.32
Ubuntu 18.04 with 4.17.0-041700.201806041953
Ubuntu 18.04 with 4.18.3-041803.201808180530
The test succeeds on Ubuntu 16.04 with 4.4.0.131.137 which makes it a
regression.
System information:
Ubuntu 4.15.0-30.32-generic 4.15.18
Description: Ubuntu 18.04.1 LTS
Release: 18.04
See below for a patch which is working for me. I'm currently using
linux kernel 4.15.0-32.35 built from git://kernel.ubuntu.com/ubuntu
/ubuntu-bionic.git with this patch.
