Do we have any experts on systemd and connman? I did find a little more data on some of our mystery autobuilder ping failures:
Ping issues on systemd images ============================= This failed with my ping test debugging present so we got more info. The host was unreachable. https://autobuilder.yoctoproject.org/typhoon/#/builders/102/builds/2888/steps/12/logs/stdio I reran the testimage and it passed. I diff'd the qemu console log output and there wasn't any difference that was meaningful. The testimage log output wasn't meaningful. I did find this interesting though: pokybuild@ubuntu1804-ty-3:~/yocto-worker/qemumips-alt/build/build/tmp/log/runtime-hostdump/202204051947_qemu$ cat target_00_ip 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,DYNAMIC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 52:54:00:12:34:06 brd ff:ff:ff:ff:ff:ff inet 169.254.89.149/16 brd 169.254.255.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::5054:ff:fe12:3406/64 scope link valid_lft forever preferred_lft forever The :06 at the end of the mac address shows it was the right qemu and I couldn't find any other qemu using 192.168.7.6 on that machine at the time. Note there is no ip address configured for that interface. I suspect something in systemd+connman is causing this intermittently. We need better network interface debug enabled in connman/systemd so we can attempt to debug this further. Any pointers on how to do that very welcome! Cheers, Richard
