network: change license of examples to MIT-0 Arguably, CC0 is just fine for examples since they are not code. But it's easier to be consistent and just use MIT-0 for all "documentation". Thus, the license is changed similarly code examples under man/. Based on 'git shortlog -ns network/*' and 'git log -p', the following folks should ack this: Zbigniew Jędrzejewski-Szmek Lennart Poettering Tom Gundersen Yu Watanabe Daan De Meyer Marc-André Lureau

network: add automatic configuration for the networks created by nspawn --network-zone= This way, they "just work", similar to --network-veth behaves, as long as networkd is enabled and running on all involved nodes.

# This network file matches the container-side of the virtual Ethernet link

# details.
networkd/nspawn: enable dhcp client on veth device created in guest When starting systemd-nspawn with --network-veth, we create a veth device called host0 in the guest. Pick up on this and start a dhcp client on it. We will also pick up host0 netdevs created by other containers should they chose to use the same name.

network: use Kind= instead of Driver= networkd ignores errors in reading driver through ethtool. The kind of network interface is retrieved through netlink, and networkd checks checks many failures. So, using Kind= should be safer. No functional change, just for safety.

networkd: introduce an AddressFamilyBoolean enum type This introduces am AddressFamilyBoolean type that works more or less like a booleaan, but can optionally turn on/off things for ipv4 and ipv6 independently. THis also ports the DHCP field over to it.

network: fix 'LinkLocal' -> 'LinkLocalAddressing' in network files 'LinkLocal' was renamed to 'LinkLocalAddressing' in: commit 56fd6bf795926409b087bce406ea851ad89f9fe8 Author: Tom Gundersen <teg@jklm.no> Date: Sat Feb 14 00:32:26 2015 +0100 networkd: .network - rename LinkLocal to LinkLocalAddressing ..but apparently the network files were not updated. Fix this.

network: turn on LLDP tx+rx for the default container network configuration Containers are relatively trusted and the veth tunnels are small networks, hence let's turn on LLDP both ways for them.

LLDP=yes
network: allow LLDP packets to cross non-customer bridges for container network interfaces This changes the default .network files we ship for nspawn containers to set EmitLLDP=customer-bridge in order to allow propagation of the LLDP packets across bridges. This is useful so that "networkctl status" shows all peers connected to a virtual container network, collecting this data via LLDP. This is safe since the default configuration for these interfaces does not bridge these links to external interfaces, but relies on IP routing for this.

EmitLLDP=customer-bridge
network: turn on DHCP timezone passing between container and host Let's turn on DHCP timezone passing from the host to a container, so that the timezone is always in sync.
