2014-02-18man: minor fixes to networkd pageTom Gundersen
Also enforce that we don't allow setting the Broadcast for IPv6 addresses.
2014-02-18sd-rtnl-message: store reference to the bus in the messageTom Gundersen
This mimics the sd-bus api, as we may need it in the future.
2014-02-17networkd: act on lease only if there is oneUmut Tezduyar Lindskog
Interface could go down before acquiring a dhcp lease
2014-02-15sd-rtnl: always include linux/rtnetlink.hTom Gundersen
2014-02-15sd-rtnl: message_open_container - don't take a 'size' argumentTom Gundersen
We can always know the size based on the type, so let's do this inside the library.
2014-02-13rtnl: support adding VETH_INFO_PEER containers into rtnl messagesLennart Poettering
2014-02-13rtnl: rename constructors from the form sd_rtnl_xxx_yyy_new() to ↵Lennart Poettering
sd_rtnl_xxx_new_yyy() So far we followed the rule to always indicate the "flavour" of constructors after the "_new_" or "_open_" in the function name, so let's keep things in sync here for rtnl and do the same.
2014-02-13rtnl: drop "sd_" prefix from cleanup macrosLennart Poettering
The "sd_" prefix is supposed to be used on exported symbols only, and not in the middle of names. Let's drop it from the cleanup macros hence, to make things simpler. The bus cleanup macros don't carry the "sd_" either, so this brings the APIs a bit nearer.
2014-02-13networkd: correctly handle manager_free(NULL)Tom Gundersen
2014-02-12networkd: work inside containersTom Gundersen
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.
2014-02-10networkd: link - correctly skip state ENSLAVING when no vlans configuredTom Gundersen
This fixes a regression introduced in 672682a6b
2014-02-10networkd: VLAN - allow multiple vlans to be created on a linkTom Gundersen
Also limit the range of vlan ids. Other implementations and documentation use the ranges {0,1}-{4094,4095}, but we use the one accepted by the kernel: 0-4094. Reported-by: Oleksii Shevchuk <alxchk@gmail.com>
2014-02-10networkd: fix setting dns from dhcpTom Gundersen
2014-02-07remove unused variablesThomas Hindoe Paaboel Andersen
2014-02-07networkd: netdev - rename Netdev to NetDevTom Gundersen
Both in the configuration file format and everywhere else in the code.
2014-02-07sd-dhcp-client: split sd_dhcp_lease from sd_dhcp_clientTom Gundersen
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.
2014-02-01networkd: remove unused variableTom Gundersen
2014-02-01networkd: don't fail on DHCP errorsTom Gundersen
2014-01-31networkd: dhcp - refactor handlerTom Gundersen
2014-01-31networkd: don't check for ifindex in answer to RTM_NEWLINKTom Gundersen
The kernel will not be changed to support this, so drop the code. Listening for all RTM_NEWLINK messages and filtering on name is reliable, so it is not a problem.
2014-01-30networkd: netdev - reduce chance of race when receiving netdev's ifindexTom Gundersen
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.
2014-01-30sd-dhcp-client/net-util: make netmask_to_prefixlen genericTom Gundersen
This was originally included in the dhcp-client at my request, but it is not really dhcp-specific and useful outside of it, so let's pull it out.
2014-01-30networkd: address - add support for broadcastTom Gundersen
2014-01-30net-util: verify the address familyTom Gundersen
Error out if the address family is already set to something incompatible with the address being parsed.
2014-01-30networkd: dhcpv4 - add notion of 'CriticalConnection'Tom Gundersen
These connections are never torn down, even when the DHCP specifications say that they should be. This is useful/necessary when the rootfs (or another critical fs) is mounted over this network connection, and dataloss would result if the connection is lost. This option defaults to off, but our initrd generator (TBD) will enable it when applicable.
2014-01-25networkd: improve logging a bitTom Gundersen
Fix/add some structured logging messages, and be uniform about when we WARN and ERR.
2014-01-25networkd: add basic VLAN supportTom Gundersen
2014-01-22sd-rtnl: simplify sd_rtnl_message_addr_new()Tom Gundersen
Split out into sd_rtnl_message_addr_set_{prefixlen,flags,scope}().
2014-01-22networkd: add basic bonding supportTom Gundersen
Refactor bridging support to be generic netdev support and extend it to cover bonding as well.
2014-01-22sd-rtnl: link - allow setting the change maskTom Gundersen
2014-01-19networkd: use 'up'/'down' rather than 'on'/'off'Tom Gundersen
2014-01-18networkd: dhcp - by default ignore the MTUTom Gundersen
2014-01-18sd-dhcp-client: refactor client_{free,new}Tom Gundersen
Make them more simiar to sd_bus and friends. Also factor out the event attachment. In the future, we will likely want to support external main-loops, so this is a first step. For the time being, we are still requiring an sd_event to be attached though.
2014-01-18sd-dhcp-client/networkd: add domainname supportTom Gundersen
2014-01-18networkd: don't hard depend on system busTom Gundersen
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.
2014-01-18networkd: resolv.conf - reword commentTom Gundersen
Take into account that users may want to use resolvconf(8), or similar. Also, avoid repeated calls to fputs().
2014-01-16networkd: resolv.conf - extend the comment a bitTom Gundersen
2014-01-16sd-dhcp-client: refactor DNS supportTom Gundersen
Rather than keeping an array of pointers to addresses, just keep an array of addresses.
2014-01-16sd-dhcp-client/networkd: add transient hostname supportTom Gundersen
2014-01-16networkd: dhcp - only set the MTU option onceTom Gundersen
Only set MTU request when creating the dhcp client, not every time it is restarted.
2014-01-16networkd: link - only save original MTU when necessaryTom Gundersen
2014-01-16networkd: improve loggingTom Gundersen
2014-01-16sd-dhcp-client/networkd: add interface MTU supportTom Gundersen
2014-01-13networkd: DHCPv4 - allow opting out of using DNS serversTom Gundersen
Setting UseDNS=no will ignore any received DNS servers.
2014-01-12networkd: fix wordingTom Gundersen
2014-01-12networkd: generate resolv.confTom Gundersen
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.
2014-01-12networkd: bridge - remove redundant stateTom Gundersen
We will not insist on getting the reply from rtnl that the bridge was created before considering the bridge ready, as we will be notified about that via udev. We will listen for the rtnl response however, in case the creation of the bridge failed.
2014-01-12networkd: don't automatically reload config at runtimeTom Gundersen
We don't know if the config will be consistent, so do as systemd itself and only load config when the daemon starts (and possibly, in the future, when explicitly requested).
2014-01-12networkd: improve logging a bitTom Gundersen
2014-01-11network: use GNU-ism to simplify macrosZbigniew Jędrzejewski-Szmek
Thanks David!
