[Bug 2115790] Re: autopkgtest failures against iproute2/6.14.0-1ubuntu2 and ethtool/1:6.14.1-1
I talked with @smb today. The iproute2 issue seems to be related to the
Ubuntu FAN implementation.
There is the "info: Using default fan map value (34)\nlocal 10.10.10.42"
message in between the "ip -d a show dev vx0" output.
Local reproducer for the iproute2 issue (running on a Noble host):
$ autopkgtest -U netplan.io --test-name=tunnels -s --add-apt-source "deb-src http://archive.ubuntu.com/ubuntu questing main" --apt-pocket=proposed=src:iproute2 -- lxd autopkgtest/ubuntu/questing/amd64
Inside the (failed) environment, we can then run:
# python3 tests/integration/tunnels.py -k vxlan
A workaround in the Netplan tests would be to just ignore the trailing whitespace ahead of ' local ...', or replacing it by a '\s' regex to match any whitespace (like the new '\n'). But this would only lead to a failure a few lines later, where we try to match iproute2's JSON output.
Simple reproducer:
$ cat /etc/netplan/tun.yaml

$ ip -j -d a show dev vx0 | jq
jq: parse error: Invalid numeric literal at line 1, column 383
=> iproute2's JSON output is actually corrupted by the "info: Using default fan map value (34)\n" message. This will break not just Netplan tests, but might affect many more packages. So should be fixed in iproute2. Maybe by moving this warning to stderr?
** Changed in: iproute2 (Ubuntu)
