We will still use the compiled-in defaults if no DNS entry exists in the config file.
|
|
This way we preserve the order of preference.
|
|
Similarly to NTP servers, this can be set at compile-time.
|
|
Also, keep the kmod_new internal to networkd-manager.c

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 is proof-of-concept only, as we only log the changes but don't do anything
with it.
|
|
The bitmask is deprecated in the kernel, so move to the new interface. At the moment
this does not make a difference for us, but it avoids having to change the API in the future.

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.
|
|
This makes updating link status on netdev links work again.
|
|
Free networks before links (the reverse of creation order).
|
|
|
|
We match 'newlink' messages with expected netdev's based on their names. Now also
make sure that the receieved link has the expected kind.
|
|
Pass the mac address on to ipv4ll and dhcp clients so they always have
up-to-date information, and may react appropriately to the change.
Also drop setting the mac address from uevent, and only log when the
address actually changes.
|
|
It's HAVE_SPLIT_USR not HAVE_SPLIT_USER
|
|
|
|
This allows us to drop the repeated attempted creations of the runtime dirs during runtime.
|
|
With the new sd_rtnl_message_read_string(), there is no longer a need for
rtnl_message_get_ifname().

first (or second)
Previously the returned object of constructor functions where sometimes
returned as last, sometimes as first and sometimes as second parameter.
Let's clean this up a bit. Here are the new rules:
1. The object the new object is derived from is put first, if there is any
2. The object we are creating will be returned in the next arguments
3. This is followed by any additional arguments
Rationale:
For functions that operate on an object we always put that object first.
Constructors should probably not be too different in this regard. Also,
if the additional parameters might want to use varargs which suggests to
put them last.
Note that this new scheme only applies to constructor functions, not to
all other functions. We do give a lot of freedom for those.
Note that this commit only changes the order of the new functions we
added, for old ones we accept the wrong order and leave it like that.

:(
Don't set set **ret when returning r < 0, as matching on the errno may easily
give false positives in the future leading to null pointer dereference.

Udev does not run in containers, so instead of relying on it to tell us when a
network device is ready to be used by networkd, we simply assume that any
device was fully initialized before being added to the container.
|
|
Both in the configuration file format and everywhere else in the code.
|
|
This allows us users of the library to keep copies of old leases. This is
used by networkd to know what addresses to drop (if any) when the lease
expires.
In the future this may be used by DNAv4 and sd-dhcp-server.
|
|
When creating a new link, the kernel will not inform us about the new ifindex
in its ack. We have to listen for newly created devices and deduce the new
ifindex by matching on the ifname.
We used to do this by waiting for a new device from libudev, but that is asking
for trouble, as udev will happily rename the device before handing it to us.
Listen on rtnl instead, the chance of the name being changed before reaching us
is much smaller (if not nil).
Kernel patch in the works to make this unneccessary.

Refactor bridging support to be generic netdev support and extend it to
cover bonding as well.
|
|
|
|
We may not have a dbus daemon in the initrd (until we can rely on kdbus). In
this case, simply ignore any attempts at using the bus. There is only one user
for now, but surely more to come.
In order to work reliably in the real root without kdbus, but at the same time
don't delay boot when kdbus is in use, order ourselves after dbus.service.

Take into account that users may want to use resolvconf(8), or similar. Also,
avoid repeated calls to fputs().
|
|
|
|
Rather than keeping an array of pointers to addresses, just keep an array of addresses.
|
|

This adds support to generate a basic resolv.conf in /run/systemd/network.
This file will not take any effect unless a symlink is created from
/etc/resolv.conf.
Nameservers received over DHCP takes precedence over statically configured ones.
Note: /etc/resolv.conf is severely limited, so in the future we will likely
rather provide a much more powerfull nss plugin (or something to that effect),
but this should allow current users to function without any loss of
functionality.

This debug information may be useful when comapring to dropped rtnetlink messages.
|
|
This gives a bit better messages when a link is added twice.
|
|
|
|
If a network is not (yet) set for a link, we do not care about its state (as we
anyway don't know what to do with it).
|
|
Remove redundant messages, add some debugging ones and make wording more uniform.

matches
Instead of checking each device after we got it, check wuth an
enumeration filter instead, to make it more efficient.
|
|
udev initialization
Managers shouldn't pick up the devices the manage before udev finished
initialization, hence check explicitly for that.
