2016-06-09networkd: clean up vlan handling a bit (#3478)Lennart Poettering
Let's add a generic parser for VLAN ids, which should become handy as preparation for PR #3428. Let's also make sure we use uint16_t for the vlan ID type everywhere, and that validity checks are already applied at the time of parsing, and not only whne we about to prepare a netdev. Also, establish a common definition VLANID_INVALID we can use for non-initialized VLAN id fields.

2016-06-07networkd: rename IPv6AcceptRouterAdvertisements to IPv6AcceptRALennart Poettering
The long name is just too hard to type. We generally should avoid using acronyms too liberally, if they aren't established enough, but it appears that "RA" is known well enough. Internally we call the option "ipv6_accept_ra" anyway, and the kernel also exposes it under this name. Hence, let's rename the IPv6AcceptRouterAdvertisements= setting and the [IPv6AcceptRouterAdvertisements] section to IPv6AcceptRA= and [IPv6AcceptRA]. The old setting IPv6AcceptRouterAdvertisements= is kept for compatibility with older configuration. (However the section [IPv6AcceptRouterAdvertisements] is not, as it was never available in a published version of systemd.
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".

2016-06-02networkd-ndisc: do not start DHCPv6 when after NDISC timeoutTom Yan
For it's silly and unnecessary. Although it was apparently mandated by RFC 2462 in [5.5.2. Absence of Router Advertisements], that has been changed in the same section of RFC 4862, which obsoleted the former RFC.
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

2016-05-26ipv4ll: change "seed" parameter to be uint64_tLennart Poettering

2016-05-26sd-network: rename "index" field of the various clients to "ifindex"Lennart Poettering
A field "index" is not particularly precise and also might conflict with libc's index() function definition. Also, pretty much everywhere else we call this concept "ifindex", including in networkd, the primary user of these libraries. Hence, let's fix this up and call this "ifindex" everywhere here too.
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.

2016-05-18networkd: Drop IPv6LL address when link is downSusant Sahani
Now we are not dropping the IPv6LL address when link is down. So next time when link is up and before kernel acquired this address we are using the old address. When the link is down kernel tells us that this address is no longer valid . Let's remove this address and again when kernel tells us that the address is added let's use it. fixes #3264

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>
2016-05-17network: test MAC address parsingDaniel Kahn Gillmor
networkd currently silently accepts some strings as MAC addresses that it probably shouldn't (like "ab:cd:ef:12:34:56:78" and "ab:cd:ef:12:3 4:56"). Add tests to MAC address parsing to ensure that we only accept valid MAC addresses, and that we accept the three most common forms of MAC address (colon-delimited hex, IEEE, and Cisco) Several of these tests currently fail, but another commit in this series will resolve them.
