udev initialization
Managers shouldn't pick up the devices the manage before udev finished
initialization, hence check explicitly for that.

We were entering BRIDGE_STATE_CREATED rather than BRIDGE_STATE_READY.
|
|
Rework the state-machine a bit.
|
|
We are likely to track more than the flags in the future.

Drop most of the arguments and instead introduce set_dst_prefixlen().
|
|
Drop most of the arguments and instead introduce link_set_{flags,type}.

We really should return errors from event handlers if we have a
continous problem and don't know any other solution.

Adds a new call sd_event_set_watchdog() that can be used to hook up the
event loop with the watchdog supervision logic of systemd. If enabled
and $WATCHDOG_USEC is set the event loop will ping the invoking systemd
daemon right after coming back from epoll_wait() but not more often than
$WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than
$WATCHDOG_USEC/4*3, to make sure the service manager is called in time.
This means that setting WatchdogSec= in a .service file and calling
sd_event_set_watchdog() in your daemon is enough to hook it up with the
watchdog logic.

This listens to rtnetlink for changes to IFF_UP and IFF_LOWER_UP (link sense). The latter
is simply logged at the moment, but will be useful once we add dhcp support.

If any number of arguments are given, _cleanup_manager_free_ is used
with unitialized memory causing a crash.

A bridge is specified in a .netdev file with a section [Bridge]
and at least the entry Name=.
A link may be joined to a bridge if the .network applied to it has
a Bridge= entry giving the name of the bridge in its [Network] section.
We eagerly create all bridges on startup, and links are added to
bridges as soon as they both appear.

In particular, store the ifname, though we should only use it carefully, as
it is not guaranteed to be stable. Using it for logging is fine though.

uint64_t can be formatted correctly with %ju, rather than casting to
unsigned and potentially losing accuracy.

This will allow specifying more options per address than the
simple Address= entry in the [Network] section.
Preliminary support for the same functionality for [Route] sections
are added, but not yet hooked up, as more testing is needed.

Pass on the line on which a section was decleared to the parsers, so they
can distinguish between multiple sections (if they chose to). Currently
no parsers take advantage of this, but a follow-up patch will do that
to distinguish
[Address]
Address=192.168.0.1/24
Label=one
[Address]
Address=192.168.0.2/24
Label=two
from
[Address]
Address=192.168.0.1/24
Label=one
Address=192.168.0.2/24
Label=two

Forgot to 'git add'...
|

Also start earlier during boot.
|
|
Also, don't fail a link just because we can't find its MAC address.

This removed the requirement for devices to be tagged with
'systemd-networkd' before they will be visible to networkd.
Still, as by default we don't ship any .network files, network
devices will simply be tracked, but not touched, unless the
admin configures things explicitly.

Follow the equivalent rename in sd-bus to stay as similar as possible.

it everywhere
Try to emphasize a bit that there should be a mapping between event
loops and threads, hence introduce a logic that there's one "default"
event loop for each thread, that can be queried via
"sd_event_default()".

One of the tests were assuming the network configuration dirs exist. We
can't do that, so disable it for now.

This daemon listens for and configures network devices tagged with
'systemd-networkd'. By default, no devices are tagged so this daemon
can safely run in parallel with existing network daemons/scripts.
Networks are configured in /etc/systemd/network/*.network. The first .network
file that matches a given link is applied. The matching logic is similar to
the one for .link files, but additionally supports matching on interface name.
The mid-term aim is to provide an alternative to ad-hoc scripts currently used
in initrd's and for wired setups that don't change much (e.g., as seen on
servers/and some embedded systems).
Currently, static addresses and a gateway can be configured.
Example .network file:
[Match]
Name=wlp2s0
[Network]
Description=My Network
Gateway=192.168.1.1
Address=192.168.1.23/24
Address=fe80::9aee:94ff:fe3f:c618/64
