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 network: renderer: networkd version: 2 tunnels: vx0: mode: vxlan id: 1337 link: eth0 local: 10.10.10.42 remote: 224.0.0.5 # multicast group ttl: 64 aging: 100 port: 4567 port-range: [4000, 4200] mac-learning: false short-circuit: true notifications: [l2-miss, l3-miss] checksums: [udp, zero-udp6-tx, zero-udp6-rx, remote-tx, remote-rx] # sd-networkd only ethernets: eth0: addresses: [10.10.10.42/24] $ netplan apply $ ip -j -d a show dev vx0 [{"ifindex":165,"ifname":"vx0","flags":["BROADCAST","MULTICAST","UP","LOWER_UP"],"mtu":1450,"qdisc":"noqueue","operstate":"UNKNOWN","group":"default","txqlen":1000,"link_type":"ether","address":"12:4f:d1:8f:6d:2f","broadcast":"ff:ff:ff:ff:ff:ff","promiscuity":0,"allmulti":0,"min_mtu":68,"max_mtu":65535,"linkinfo":{"info_kind":"vxlan","info_data":{"id":1337,"group":"224.0.0.5"info: Using default fan map value (34) ,"local":"10.10.10.42","link":"eth0","port_range":{"low":4000,"high":4200},"port":4567,"ttl":64,"df":"unset","ageing":100,"external":false,"learning":false,"proxy":false,"rsc":true,"l2miss":true,"l3miss":true,"udp_csum":true,"udp_zero_csum6_tx":true,"udp_zero_csum6_rx":true,"remcsum_tx":true,"remcsum_rx":true,"localbypass":true}},"num_tx_queues":1,"num_rx_queues":1,"gso_max_size":65536,"gso_max_segs":65535,"tso_max_size":524280,"tso_max_segs":65535,"gro_max_size":65536,"gso_ipv4_max_size":65536,"gro_ipv4_max_size":65536,"addr_info":[{"family":"inet6","local":"fe80::104f:d1ff:fe8f:6d2f","prefixlen":64,"scope":"link","protocol":"kernel_ll","valid_life_time":4294967295,"preferred_life_time":4294967295}]}] $ 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) Assignee: (unassigned) => Stefan Bader (smb) ** Summary changed: - autopkgtest failures against iproute2/6.14.0-1ubuntu2 and ethtool/1:6.14.1-1 + autopkgtest failures against iproute2/6.14.0-1ubuntu2 (FAN) and ethtool/1:6.14.1-1 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.
