2017-02-11networkd: add IPv6ProxyNDPAddress support (#5174)Florian Klink
IPv6 Neighbor discovery proxy is the IPv6 equivalent to proxy ARP for IPv4. It is required when ISPs do not unconditional route IPv6 subnets to their designated target, but expect neighbor solicitation messages for every address on a link. A variable IPv6ProxyNDPAddress= is introduced to the [Network] section, each representing a IPv6 neighbour proxy entry in the neighbour table.
2016-12-21networkd: bond support primary slave and active slave (#4873)Susant Sahani
active_slave: Specifies the new active slave for modes that support it (active-backup, balance-alb and balance-tlb). primary slave: systemd-networks currently lacks the capability to set the primary slave in an active-backup bonding. This is necessary if you prefer one interface over the other. A common example is a eth0-wlan0 bonding on a laptop where you'd want to switch to the wired connection whenever it's available. Fixes: #2837

2016-12-05networkd: link_enter_configured remove assert (#4800)Susant Sahani
When we are in link_enter_configured we assume that the link->state should be LINK_STATE_SETTING_ROUTES but in some situation it's LINK_STATlE_SETTING_ADDRESSES. Just ignore the wrong state. Also since the return value not used any where make link_enter_configured return type void. Fixes: #4746

2016-11-21networkd: do not automatically propagate bogus DNS/NTP serversLennart Poettering
Never propagate DNS/NTP servers on the local link via the DHCP server. The DNS/NTP servers 0.0.0.0 and 127.0.0.1 only make sense in the local context, hence never propagate them automatically to other hosts. Fixes: #4524

2016-11-21networkd: store DNS servers configured per-network as parsed addressesLennart Poettering

2016-09-24networkd: do not drop config for pending interfaces (#4187)Martin Pitt
While an interface is still being processed by udev, it is in state "pending", instead of "unmanaged". We must not flush device configuration then. Further fixes commit 3104883ddc24 after commit c436d55397. Fixes #4186

2016-06-06network: beef up ipv6 RA support considerablyLennart Poettering
This reworks sd-ndisc and networkd substantially to support IPv6 RA much more comprehensively. Since the API is extended quite a bit networkd has been ported over too, and the patch is not as straight-forward as one could wish. The rework includes: - Support for DNSSL, RDNSS and RA routing options in sd-ndisc and networkd. Two new configuration options have been added to networkd to make this configurable. - sd-ndisc now exposes an sd_ndisc_router object that encapsulates a full RA message, and has direct, friendly acessor functions for the singleton RA properties, as well as an iterative interface to iterate through known and unsupported options. The router object may either be retrieved from the wire, or generated from raw data. In many ways the sd-ndisc API now matches the sd-lldp API, except that no implicit database of seen data is kept. (Note that sd-ndisc actually had a half-written, but unused implementaiton of such a store, which is removed now.) - sd-ndisc will now collect the reception timestamps of RA, which is useful to make sd_ndisc_router fully descriptive of what it covers. Fixes: #1079
2016-06-06lldp: add proper ref counting to sd_lldp object and a separate call for ↵Lennart Poettering
setting the ifindex Let's make sd-lldp a bit more like sd-ndisc ant the other APIs, and add proper ref counting and a separate call for setting the ifindex. This also adds a new lldp_reset() call we can use at various places to close all fds. This is also similar to how sd-ndisc already does it.

2016-06-03networkd: drop weird "const" usage in function parametersLennart Poettering
We generally only use "const" to constify the destination of pointers, but not the pointers themselves, as they are copied anyway during C function invocation. Hence, drop this usage of "const".
2016-06-01networkd-dhcp6: generalize DHCPv6 client (re)startingTom Yan
dhcp6_request_address() was merely a function to switch the DHCPv6 client from "stateless" mode to "stateful" mode. It was also a one-way switch. Also, to (re)start the client, we would need to repeat separate function calls. In this patch, dhcp6_request_address() is made a general starter/manager of the DHCPv6 client. It now takes an extra parameter so we will be specifying which mode the DHCPv6 client should be started in. Also it will keep track of the current mode and compare with the newly requested mode, and only restart the client in case there is a difference between them. This also makes sure that the DHCPv6 client will be (re)started accordingly as per the Router Advertisement flags.

2016-05-28networkd: disable IPv6 for bridge slaveTom Yan
If an interface is managed as a bridge slave, we don't want any IP configuration for it. Therefore, disable IPv6 in such case.
2016-05-28networkd: unset master if not enslaved with networkdTom Yan
When we manage an interface with networkd but not as a slave (i.e. no `Bridge=` or `Bond=` set in its .network), we do not want it to remain slaved.
2016-05-25networkd: Disable IPv6 when DHCPv6 is only enabledTom Yan
DHCPv6 requires an IPv6 link-local address to work. The client will not be started (even when enabled explicitly with `DHCP=`) if none is configured (either by autoconfiguration or manually). Therefore, disable IPv6 in such case.
2016-05-25networkd: set IFLA_INET6_ADDR_GEN_MODE as per stable_secretTom Yan
Although networkd has option (LinkLocalAddressing=) to toggle IPv6LL autoconfiguration, when it is enabled, the address is autoconfigured by the kernel, but not networkd. Therefore, we do not statically set IFLA_INET6_ADDR_GEN_MODE to IN6_ADDR_GEN_MODE_EUI64, but dynamically depending on whether stable_secret is set, just as what the kernel does by default. Note that this does NOT affect the global addresses configured by networkd.

2016-05-17networkd: Add EmitRouter= option for DHCP Server (#3251)Clemens Gruber
Add an option to disable appending DHCP option 3 (Router) to the DHCP OFFER and ACK packets. This commit adds the boolean option EmitRouter= for the [DHCPServer] section in .network files. Rationale: On embedded devices, it is very useful to have a DHCP server running on an USB OTG ethernet gadget interface to avoid manual setup on the client PCs, but it should only serve IP addresses, no route(r)s. Otherwise, Windows clients experience network connectivity issues, due to them using the address set in DHCP option 3 as default gateway. Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>

2016-05-09networkd: reworkd LLDP emission to allow control of propagation levelLennart Poettering
This allows selecting the propagation level of emitted LLDP packets (specifically: the destination MAC address of the packets). This is useful because it allows generating LLDP packets that optionally cross certain types of bridges. See 802.11ab-2009, Table 7-1 for details.
2016-05-03networkd: rework duid_{type,duid_type,duid,duid_len} settingZbigniew Jędrzejewski-Szmek
Separate fields are replaced with a struct. Second second duid type field is removed. The first field was used to carry the result of DUIDType= configuration, and the second was either a copy of this, or contained the type extracted from DuidRawData. The semantics are changed so that the type specified in DUIDType is always used. DUIDRawData= no longer overrides the type setting. The networkd code is now more constrained than the sd-dhcp code: DUIDRawData cannot have 0 length, length 0 is treated the same as unsetting. Likewise, it is not possible to set a DUIDType=0. If it ever becomes necessary to set type=0 or a zero-length duid, the code can be changed to support that. Nevertheless, I think that's unlikely. This addresses #3127 § 1 and 3. v2: - rename DUID.duid, DUID.duid_len to DUID.raw_data, DUID.raw_data_len
2016-04-29networkd: rework headers to avoid circular includesZbigniew Jędrzejewski-Szmek
Header files were organized in a way where the includer would add various typedefs used by the includee before including it, resulting in a tangled web of dependencies between files. Replace this with the following logic: networkd.h / \ networkd-link.h \ networkd-ipv4ll.h--\__\ networkd-fdb.h \ networkd-network.h netword-netdev-*.h networkd-route.h \ networkd-netdev.h If a pointer to a structure defined in a different header file is needed, use a typedef line instead of including the whole header.
