** Description changed: 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.
