<pre>As the summary says, systemd-networkd fails to bring the interface up if ipv6
is disabled with the ipv6.disable=1 kernel parameter. This is a regression on
systemd 219 as with 218 it was working.
The ip address configured in the respective .network file is assigned to the
interface, in my case a bridge create with a .netdev file, but the interface
will be down.
<span class="quote">> ip a s brkvm</span >
4: brkvm: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default
link/ether 36:98:33:12:74:df brd ff:ff:ff:ff:ff:ff
inet 192.168.56.1/24 brd 192.168.56.255 scope global brkvm
valid_lft forever preferred_lft forever
In this case the output on the journal is as follows:
<span class="quote">> journalctl -b -u systemd-networkd -o cat</span >
Starting Network Service...
brkvm : netdev ready
Enumeration completed
Started Network Service.
brkvm : Cannot configure IPv6 forwarding for interface: No such file
or directory
brkvm : brkvm : could not bring up interface: Address
family not supported by protocol
brkvm : link configured
wlan0 : gained carrier
If ipv6 is not disabled then the ipv4 address I'm trying to set will be
assigned to the interface and the interface will be brought up.</pre>
