[systemd-devel] VLAN's not coming up "systemd-networkd.service loaded failed" + systemd-networkd seg fault

[Brendan Horan]

Hi,

I am trying configure VLAN sub interfaces with networkd.

When the machine boots the physical interface never seems to come UP.
Thus all the sub interface VLAN's also do not get activated.

I also notice systemd-networkd seg faults during boot, example message :
--------------------------------------------
"[    7.036581] systemd-network[677]: segfault at 255 ip 00007f88955634c9 sp 00007fffb34fd8b0 error 4 in systemd-networkd[7f8895559000+86000]
[    7.093289] systemd-network[682]: segfault at 255 ip 00007f3cd632e4c9 sp 00007fff25936ed0 error 4 in systemd-networkd[7f3cd6324000+86000]
--------------------------------------------

If I then manually bring up my physical interface the VLAN sub interfaces get created. 
I am not sure what I am doing wrong and what is causing systemd-networkd to seg fault.


My configs are as follows :

If you need more info I am happy to try provide it.

Thank you, (and thanks for systemd!)
