To make sure we don't delay boot on systems where (some) network links are managed by someone else
we don't block if something else has successfully brought up a link.
We will still block until all links we are aware of that are managed by networkd have been
configured, but if no such links exist, and someone else have configured a link sufficiently
that it has a carrier, it may be that the link is ready so we should no longer block.
Note that in all likelyhood the link is not ready (no addresses/routes configured),
so whatever network managment daemon configured it should provide a similar wait-online
service to block network-online.target until it is ready.
The aim is to block as long as we know networking is not fully configured, but no longer. This
will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't
know whether networkd is the main/only network manager.
Even in the case networking is fully configured by networkd, the default behavior may not be
sufficient: if two links need to be configured, but the first is fully configured before the
second one appears we will assume the network is up. To work around that, we allow specifying
specific devices to wait for before considering the network up.
This unit is enabled by default, just like systemd-networkd, but will only be pulled in if
anyone pulls in network-online.target.

systemd-analyze plot > test.svg produces output with all y and height
element attributes equal to zero. This of course causes the resulting
svg to appear blank (zero height). Bug does not affect x86. Looks like
a compiler optimization may be the culprit.

Let's unify generation of unicode chars at one place.
Also, don't add an extra space into chars we print, except for the tree
chars where this is really necessary.

We shouldn't silently tape over broken kernel drivers.

This function is no longer just about muteing the VT. We do all kinds of
VT setup for sessions using the controller-API. Rename the function to
something more appropriate.
|
|
The tty associated with a VT should be owned by the owner of the session
running on the VT. This is important for supporting a socket activated X
server, since the X server will open the tty itself.
This commit makes sure to chown the tty any time a session is
created and and chown it back to root any time the session
is removed. This behavior is copied from /bin/login.

This properly detects the state of the link based on both the link flags and the
operstate.
Moreover, always log state-changes even if we are not yet managing the link.
|
|
Avoid having two code-paths racing with eacother to do the same thing. The change
of flags will be detected in the normal way, so only use the link_up_handler
to detect if the 'up' failed and in that case fail the link.

This reverts commit cdc85c875b842b9309f72caefc51c262f521cf92.
There appears to be a kernel bug that (among other things) cause bridges
not to get a bridge id set when supplying IFLA_ADDRESS when creating the
netdev.
Simply revert the whole thing until we sort this out in the kernel.
See: http://www.spinics.net/lists/netdev/msg279807.html

When rebooting with systemctl, an optional argument can be passed to the
reboot system call. This makes it possible the specify the argument in a
service file and use it when the service triggers a restart.
This is useful to distinguish between manual reboots and reboots caused by
failing services.

And move it to sperate function.

Cases where name_to_handle_at is used allocated the full struct to be
MAX_HANDLE_SZ, and assigned this size to handle_bytes. This is wrong
since handle_bytes should describe the length of the flexible array
member and not the whole struct.
Define a union type which includes sufficient padding to allow
assignment of MAX_HANDLE_SZ to be correct.

MAC addreses are also set when NEWLINK messages are receieved, but only if the clients have
already been initialized.
|

|
Should be no functional change, but avoids spurious log
messages when in operstate UNKNOWN and !IFF_LOWER_UP.
|
|
Drop leading zeros which will never be used when printing the link flags.
|
|
The address may be already changed by other processes, or set
when creating the netdev from userspace.

This is a second attempt at 9754d56, reverted in 2f20a8e, because
I lost a 'break;' when moving chunks around.

We may receive RTM_NEWLINK messages with missing LINKINFO after the initial NEWLINK message,
don't bother verifying these, just drop out early after checking that the ifindex is not in conflict.

This essentially swaps the roles of rtnl and udev in networkd. After this
change libudev is only used for waiting for udev to initialize devices and
to get udev-specific information needed for some [Match] attributes.
This in particular simplifies the code in containers where udev is not really
useful, but also simplifies things and reduces round-trips in the non-container
case.
