2015-03-27networkd-dhcp6: Do not handle prefix expiryPatrik Flykt
Expiring prefixes need not be handled anymore as the kernel has been instructed not to create routes for DHCPv6 assigned addresses via the IFA_F_NOPREFIXROUTE flag.
2015-03-27systemd-networkd: Use IFA_F_NOPREFIXROUTE with IPv6 addressesPatrik Flykt
The IFA_F_NOPREFIXROUTE flag prevents the kernel from creating new onlink prefixes when a DHCPv6 IPv6 address with a prefix length is set from user space. IPv6 routing will follow the onlink status from Router Advertisment Prefix Information options or any manually set route, which is the correct thing to do. As this flag has a larger value than what fits into an unsigned char, update the flag attribute to an uint32_t and set it with an IFA_FLAGS attribute when writing netlink messages to the kernel.
2015-03-21networkd: use LOG_WARN not LOG_ERR for non-fatal errorsZbigniew Jędrzejewski-Szmek
2015-03-15network: add UseNTP DHCP optionMichael Marineau
Despite having the internal logic in place to enable/disable using NTP servers provided by DHCP the network config didn't expose the option.
2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.
2015-03-07networkctl: avoid leak if a field was specified twiceZbigniew Jędrzejewski-Szmek
The input data would have to be borked, so this is unlikely to happen, but since we have a nice helper function to do it properly... why not? CID #1261390.
2015-03-04networkd: Make DHCP client ID creation configurableJan Janssen
2015-03-04networkd: netdev - inform when we take over an existing netdevTom Gundersen
The crucial point here is that we will not change the settings of a netdev created by someone else we simply use it as is and trust it was set up as intended. This is confusing in the case of the pre-created netdev's (bond0 etc.), the solution should probably be to simply make the kernel stop creating these devices as they are pretty useless.
2015-02-27networkd: add support for Uplink Failure DetectionAlin Rauta
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]
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-14networkd: network - rename ipv6token parserTom Gundersen
Too generic name.
2015-02-14networkd: .network - rename LinkLocal to LinkLocalAddressingTom Gundersen
Makes it a bit less ambiguous.
2015-02-12networkd: explicitly enable/disable ipv6ll addressesTom Gundersen
The kernel does not like getting an empty container, so just always pass the parameter, even if it is the default.
2015-02-11networkd: fdb - fix const warningTom Gundersen
2015-02-11networkd: don't do exit-on-idle if there is something wrong with the dbus ↵Tom Gundersen
connection Just fall back to plain old event loop in this (highly unlikely) case. In the glorious future when kdbus is upstream we can of course drop all this.

From: Paul Martin <paul.martin@codethink.co.uk> Date: Wed, 11 Feb 2015 11:47:16 +0000 Subject: [PATCH] networkd dhcpv4 logging endian fix On a big-endian host, systemd-networkd prints out IPv4 network addresses byte reversed: Feb 10 16:43:32 hostname systemd-networkd[151]: eth0 : DHCPv4 address 158.1.24.10/16 via 1.1.24.10 The address obtained is 10.24.1.158/16 and the route is 10.24.0.0/16 dev eth0 src 10.24.1.187 The macro ADDRESS_FMT_VAL() unpacks a "struct in_addr" in a little-endian specific manner. This patch forces the passed address into host order, then unpacks it. On an x86 later than i486, compiled with -O2, the only extra overhead is a single bswap instruction.
2015-02-10net: support globbing and disjunction in Match logicTom Gundersen
Match{Name,OrginalName,Type,Driver,Path} can now take a space-separated glob of matches.
2015-02-10networkd: fdb - refactor a bitTom Gundersen
Pass around Link objcets rather than FdbEntry objects. The link objects have an up-to-date ifname we can use for logging. match_name sholud _never_ be used for anything except matching. Firstly, it may be unset (usually is), and secondly it may not be up-to-date.
2015-02-10networkd: bus - expose MatchMACTom Gundersen
2015-02-10networkd: network-bus - use sd_bus_path_{en,de}codeTom Gundersen
2015-02-09networkd: link_object_find - don't accept invalid inputTom Gundersen
Reported by Zbigniew.
2015-02-09networkd: support route scopesTom Gundersen
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.
2015-02-09treewide: correct typos and use consistent "MAC" spellingTorstein Husebø
2015-02-09networkd: bus - switch to properly escaped object pathsTom Gundersen
2015-02-09networkd: add support for IPv6 tokensTom Gundersen
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.
2015-02-09networkd: generalize IPv4LL to LinkLocalTom Gundersen
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.
2015-02-08networkd: add basic org.freedesktop.network1.Network interfaceTom Gundersen
2015-02-08networkd: add network_get_by_nameTom Gundersen
2015-02-08networkd: use valid bus pathsMantas Mikulėnas
Object path components must start with [A-Za-z_] (AFAIK). Also the value of 'p' is undefined if asprintf fails. Compare to user_bus_path() in src/login/logind-user-dbus.c:281.
2015-02-05networkd: move the connection to the bus out of manager_new (again)Tom Gundersen
This would otherwise make the tests fail as we cannot grab the bus name.
2015-02-05networkd: gracefully handle failure to emit signals when dbus is not connectedTom Gundersen
When we get kdbus we don't need these hackse.
2015-02-05networkd: exit on idleTom Gundersen
We will be woken up on rtnl or dbus activity, so let's just quit if some time has passed and that is the only thing that can happen. Note that we will always stay around if we expect network activity (e.g. DHCP is enabled), as we are not restarted on that.
2015-02-05networkd: don't unlink state files on exitTom Gundersen
Only unlink state files on DELLINK. This allows sd-network to be used even when networkd is not running.
2015-02-05networkd: add basic dbus APITom Gundersen
Only the very basics, more to come.

2015-02-05networkd: don't warn about missing links unnecessarilyTom Gundersen
If we get a NEWLINK + NEWADDR between enumerating the links and enumerating the addresses, we would get a warning that the link corresponding to the address does not exist. This is a false warning as both the NEWLINK and NEWADDR would be processed after enumerating completed, so drop it.
2015-02-05networkd: log when finished enumerating links and addressesTom Gundersen
2015-02-03networkd: refactor socket activation a bitTom Gundersen
2015-02-03networkd: handle suspend eventsTom Gundersen
2015-02-02network-address,test-network: avoid undefined behaviourZbigniew Jędrzejewski-Szmek
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
2015-02-02networkd: minor simplificationLennart Poettering
Let's return the fd we found as return value in systemd_netlink_fd(), instead of using call-by-reference.
2015-02-02networkd: support socket activationTom Gundersen
Still keep the non-socket activation code around for starting from the commandline, but will likely drop that too in the future.
2015-02-02networkd-wait-online: add timeoutTom Gundersen
Default to timing out after 120 seconds without a network connection. Setting a timeout of 0 disables the timeout.
2015-02-02networkd-wait-online: support globbing for ignored devicesTom Gundersen
2015-01-31networkd: dhcp-server - start as soon as addresses have been setTom Gundersen
We would otherwise wait for the interface to be completely configured, which could take considerable time with IPv4LL. As a result nspawn was very slow at obtaining IP addresses.
2015-01-31networkd-wait-online: allow specific devices to be ignoredTom Gundersen
In addition to the loopback device, also explicitly configured devices to be ignored. Suggested by Charles Devereaux <systemd@guylhem.net>.
2015-01-28networkd: tunnel - call tunnel modes ipip6, not ip4ipv6 to match ip(8)Tom Gundersen
2015-01-27networkd-dhcp6: Assign DHCPv6 addresses and prefix lengthsPatrik Flykt
Once IPv6 addresses have been acquired, assign these to the interface with the prefix lengths taken from the ICMPv6 Router Advertisement handling code. The preferred and valid IPv6 address lifetimes are handed to the kernel which will clean up them if not renewed in time. When a prefix announced via Router Advertisements expires, find all addresses that match that prefix and update the address to have a prefix length of 128 causing the prefix to be off-link.
2015-01-22networkd: Introduce ip6gre and ip6gretapSusant Sahani
