Introduce BindCarrier= to indicate the set of links that determine if
the current link should be brought UP or DOWN.
[tomegun: add a bit to commit message]
|
|
Too generic name.
|
|
Makes it a bit less ambiguous.
|
|
Match{Name,OrginalName,Type,Driver,Path} can now take a space-separated glob of matches.
|
|
For now we only support the hardcoded values RT_SCOPE_{UNIVERSE,LOCAL,HOST},
and not numerical values or values from /etc/iproute2/rt_scopes.
This addresses https://bugs.freedesktop.org/show_bug.cgi?id=88508.

This allows the admin to set the host-specific part of IPv6 addresses, but still
receive the prefix via SLAAC.
.network file snippet:
[Network]
IPv6Token=::12
gives:
$ ip token
token ::12 dev eth0
This closes https://bugs.freedesktop.org/show_bug.cgi?id=81177.
|
|
This allows both IPv4 and IPv6 link-local addresses to be enabled or disabled. By default
we still enable IPv6LL and disable IPv4LL. The old config option is kept for backwards
compatibility, but removed from the documentation.

This adds two new settings to networkd's .network files:
IPForwarding=yes and IPMasquerade=yes. The former controls the
"forwarding" sysctl setting of the interface, thus controlling whether
IP forwarding shall be enabled on the specific interface. The latter
controls whether a firewall rule shall be installed that exposes traffic
coming from the interface as coming from the local host to all other
interfaces.
This also enables both options by default for container network
interfaces, thus making "systemd-nspawn --network-veth" have network
connectivity out of the box.

|
This patch integrates LLDP with networkd.
Example conf:
file : lldp.network
[Match]
Name=em1
[Network]
LLDP=yes
|
|
|
|
Let's stick to generic sections that describe the general technology,
instead of specific per-object sections, unless we really have a reason
to do that otherwise.
|
|
This allows the default link settings (set in .link files) to be overridden per Network. Only MTU and MACAddress is supported for now.
|
|
|
|
This patch add support to specify path cost of the
bridge port to be configured via conf file.
Exampe: conf
file: br.netdev
[NetDev]
Name=br-test
Kind=bridge
file: br.network
[Match]
Name=em1
[Network]
Bridge=br-test
[BridgePort]
Cost=332
bridge link
2: em1 state UP : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master
br-test state disabled priority 32 cost 332

This lets the routing metric for links to be specified per-network,
still defaulting to DHCP_ROUTE_METRIC (1024) if unspecified. Hopefully
this helps with multiple interfaces configured via DHCP.
|
|
This allows the search/routing domanis to be specified per link/network and be passed
on to resolved.
|
|
This option will also apply to the search domains, so make it plural.
|
|
|
|
|
|
This is necessary for non-ipv4ll hosts to communicate with ipv4ll-only hosts on the same link. Defaults
to being enabled, but can be opted out.
See: <http://avahi.org/wiki/AvahiAutoipd#Routes>
|
|
In the state files, do not distinguish where the various entries came from
(static or DHCP), but include them all in the same list.
|
|
It appears there is no good way to decide whether or not broadcasts should be enabled,
there is hardware that must have broadcast, and there are networks that only allow
unicast. So we give up and make this configurable.
By default, unicast is used, but if the kernel were to inform us abotu certain
interfaces requiring broadcast, we could change this to opt-in by default in
those cases.
|
|
This was accidentally dropped when adding metric support.

Vendor Class Identifier be used by DHCP clients to identify
their vendor type and configuration. When using this option,
vendors can define their own specific identifier values, such
as to convey a particular hardware or operating system
configuration or other identifying information.
Vendor-specified DHCP options—features that let administrators assign
separate options to clients with similar configuration requirements.
For example, if DHCP-aware clients for example we want to separate
different gateway and option for different set of people
(dev/test/hr/finance) in a org or devices for example web/database
servers or let's say in a embedded device etc and require a different
default gateway or DNS server than the rest of clients.
|
|
Now route metric can be configuted via conf file:
example conf:
[Match]
Name=em1
[Route]
Gateway=192.168.1.12
Metric=10
Test:
ip route output
default via 192.168.1.12 dev em1 metric 10
[tomegun: squash TODO update and reword man page a bit]

This patch adds peer address support for
networkd . In the [Address] a new configurable
param is Peer.
[Match]
Name=ipip-tun
[Address]
Address=10.0.0.1/32
Peer=10.0.0.2/32
|
|
|
|
Send hostname (option 12) in DISCOVER and REQUEST messages so the
DHCP server could use it to register with dynamic DNS and such.
To opt-out of this behaviour set SendHostname to false in [DHCP]
section of .network file
[tomegun: rebased, made sure a failing set_hostname is a noop and moved
config from DHCPv4 to DHCP]
|
|
This adds support for DHCP options 33 and 121: Static Route and
Classless Static Route. To enable this feature, set UseRoutes=true
in .network file. Returned routes are added to the routing table.
|
|
If there are v4 or v6 specific options we can keep those in separate sections,
but for the common options, we will use only one.
Moreovere only use DHCP=[yes/both|no/none|v4|v6] to enable or disable the clients.
|
|
Enable DHCPv6 support by creating a DHCPv6 boolean in the Network
section. Add necessary DHCPv6 structures and initial function calls.
|
|
This patch enables netwokd to create vxlan
Changes:
Added:
1. File networkd networkd-vxlan.c
2. to netdev
bool learning
struct in_addr group
uint64_t vxlanid;
3. VXLAN subsection and config
parameters
|
|
When enabled in [Network] it will set up a dhcp server on the interface, listening
on one of its statically configured IPv4 addresses and with a fixed size pool of
leases determined from it.
Example:
[Match]
Name=ve-arch-tree
[Network]
Address=192.168.12.5/24
DHCPServer=yes
[Route]
Gateway=192.168.12.5
Destination=192.168.12.0/24
In this case we will configure ve-arch-tree with the address 192.168.12.5 and
hand out addresses in the range 192.168.12.6 - 192.168.12.38.
In the future, we should (as suggested by Lennart) introduce a syntax to pick the
server address automatically.

This patch enables basic ipip tunnel support.
It works with kernel module ipip
example conf:
file: ipip.netdev
[NetDev]
Name=ipip-tun
Kind=ipip
MTUBytes=1480
[Tunnel]
Local=192.168.223.238
Remote=192.169.224.239
TTL=64
file: ipip.network
[Match]
Name=em1
[Network]
Tunnel=ipip-tun
[tomegun:
- drop unused variable
- take ref when enslaving]
|
|
|
|
This does not belong in shared as it is mostly a detail of our networking subsystem.
Moreover, now we can use libudev here, which will simplify things.

Implements IPv4LL with respect to RFC 3927
(http://tools.ietf.org/rfc/rfc3927.txt) and integrates it
with networkd. Majority of the IPv4LL state machine is
taken from avahi (http://avahi.org/) project's autoip.
IPv4LL can be enabled by IPv4LL=yes under [Network]
section of .network file.
IPv4LL works independent of DHCP but if DHCP lease is
aquired, then LL address will be dropped.
[tomegun: removed a trailing newline and a compiler warning]
