Description Tom Hughes 2016-06-10 09:34:08 UTC
Description of problem:

After upgrading to F24 my journal was getting spammed with messages like this every second:

Jun 10 10:11:26 host.example.com systemd-networkd[1203]: enp5s0: Starting DHCPv6 client on NDisc request failed: Invalid argument

Interface enp5s0 is joined to a bridge - it's network file looks like this:

[Match]
MACAddress=aa:bb:cc:dd:ee:ff

[Network]
Bridge=br0

It is connected to a network where the IPv6 RAs say that DHCPv6 should be used, so is starting DHCPv6 on the interface, even though it is joined to a bridge but that then fails because of the bridge presumably.

Adding IPv6AcceptRouterAdvertisements=false to make it ignore the RAs on that interface seems to fix things but maybe that should be implied when an interface is joined to a bridge?

Version-Release number of selected component (if applicable):

systemd-229-8.fc24.x86_64

It's fixed upstream in https://github.com/systemd/systemd/commit/2b00a4e03d. We probably should backport this. Seems easy enough.
