That patch works but there are now more problems with the DHCP stack inside networkd. See https://paste.ubuntu.com/23178198/ Needs more investigation.

[Touch-packages] [Bug 1623068] Re: Networkd fails to configure a ethernet network device on a 3.4 kernel
Yes, the kernel has IPv6 support enabled so socket_ipv6_is_supported() returns true and with that it tries to setup the IPv6 part of the interface. The two problems which I've found so far are: - an empty IFLA_AF_SPEC seems to cause the kernel to return EINVAL - having IPv6 enabled and IFLA_AF_SPEC is filled with the ipv6ll mode we get EINVAL So to fix this we have to do two things: 1. disable IPv6 support in the 3.4 kernel; if that is not acceptable for the real product later than we have to find another solution. 2. move the open/close_container() inside the if() statement to avoid an empty container. For 2. we may can work around this on the kernel side too to allow empty IFLA_AF_SPEC containers. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1623068 Title: Networkd fails to configure a ethernet network device on a 3.4 kernel Status in systemd package in Ubuntu: Confirmed Bug description: Knowing that a 3.4 based kernel is unsupported we have to get it working for a specific customer.

[Touch-packages] [Bug 1623068] Re: Networkd fails to configure a ethernet network device on a 3.4 kernel
Does that kernel support IPv6, i. e. does socket_ipv6_is_supported() succeed and the whole AF_INET6 setup is actually done? I. e. is the problem the mere existence of the IFLA_AF_SPEC container in the netlink message (which already isn't supported by the kernel) or only trying to set the IPv6 settings? I. e. it might help to not create the container at all if !socket_ipv6_is_supported(), i. e. move the open/close_container() inside that if()? (that would only help if the kernel has IPv6 disabled) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1623068 Title: Networkd fails to configure a ethernet network device on a 3.4 kernel Status in systemd package in Ubuntu: Confirmed Bug description: Knowing that a 3.4 based kernel is unsupported we have to get it working for a specific customer.

Just to collect all the info, can you please re-run with sudo SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd I assume this is a missing kernel feature (systemd only officially supports kernels ≤ 2 years old), so we'd need some fallback.
