networkd: Add support to configure VXLAN Port
2016-01-26util: introduce fputs_with_space() and make use of it at various placesLennart Poettering
The call combines outputing a string with prefixing it with a space, optionally. This is useful to shorten the logic for outputing lists of strings, that are space separated.
2016-01-26networkd: optinally use DHCP lease domain info for routing onlyLennart Poettering
This changes the UseDomains= setting of .network files to take an optional third value "route", in addition to the boolean values. If set, the passed domain information is used for routing rules only, but not for the search path logic.
2016-01-26networkd: rename a few Network object properties to be more like the ↵Lennart Poettering
configuration settings All booleans called dhcp_xyz are now called ".dhcp_use_xyz", to match their respective configuration file settings. This should clarify things a bit, in particular as there is a DHCP hostname that was previously called just ".hostname" because ".dhcp_hostname" was already existing as a bool. Since this confusion is removed now because the bool is called ".dhcp_use_hostname", the string field is now renamed to ".dhcp_hostname".
2016-01-26networkd: when filtering out duplicate domain names use DNS comparisonLennart Poettering
When we collect the domain names of the various links and other sources in one ordered set, make sure to use proper DNS name comparison to filter out duplicates.
2016-01-26networkd: use an OrderedSet instead of Set to collect link domainsLennart Poettering
For the search domain logic the order is highly relevant, hence make sure when collecting the various search domains to add them to an ordered set, so that the order between search domains of a specific link is retained.
2016-01-26networkctl: move strv_isempty() check into dump_list()Lennart Poettering
Previously, each invocation of dump_list() was prefixed with a call to strv_isempty() to suppress invocation of the function when the list is empty anyway. Move the check into the function itself, so that we can reduce the code a bit in size. (Also, prefix a couple of invocations we knowingly ignore return errors with a (void) cast).
2016-01-26networkd: rework Domains= settingLennart Poettering
Previously, .network files only knew a vaguely defined "Domains=" concept, for which the documentation declared it was the "DNS domain" for the network connection, without specifying what that means. With this the Domains setting is reworked, so that there are now "routing" domains and "search" domains. The former are to be used by resolved to route DNS request to specific network interfaces, the latter is to be used for searching single-label hostnames with (in addition to being used for routing). Both settings are configured in the "Domains=" setting. Normal domain names listed in it are now considered search domains (for compatibility with existing setups), while those prefixed with "~" are considered routing domains only. To route all lookups to a specific interface the routing domain "." may be used, referring to the root domain. An alternative syntax for this is the "*", as was already implemented before using the "wildcard" domain concept. This commit adds proper parsers for this new logic, and exposes this via the sd-network API. This information is not used by resolved yet, this will be added in a later commit.

2016-01-20dhcp: make DHCP_OPTION_* enum publicBeniamino Galvani
libsystemd-network provides the public function sd_dhcp_client_set_request_option() to enable the request of a given DHCP option. However the enum defining such options is defined in the internal header dhcp-protocol.h. Move the enum definition to the public header sd-dhcp-client.h and properly namespace values.
2016-01-20dhcp: export routes as opaque objectsBeniamino Galvani
At the moment sd_dhcp_lease_get_routes() returns an array of structs which are not defined in public headers. Instead, change the function to return an array of pointers to opaque sd_dhcp_route objects.

2016-01-19networkd: VXLAN add support to configure portSusant Sahani
This patch add support to configure port PortRange: VXLAN bases source UDP port based on flow to help the receiver to be able to load balance based on outer header flow. DestinatinPort: Allow configuring the default destination port on a per-device basis.

2016-01-05resolved,networkd: unify ResolveSupport enumLennart Poettering
networkd previously knew an enum "ResolveSupport" for configuring per-interface LLMNR support, resolved had a similar enum just called "Support", with the same value and similar pasers. Unify this, call the enum ResolveSupport, and port both daemons to it.
2016-01-05basic: add string table macros for "extended boolean" enumsLennart Poettering
In a couple of cases we maintain configuration settings that know an on and off state, like a boolean, plus some additional states. We generally parse them as booleans first, and if that fails check for specific additional values. This adds a generalized set of macros for parsing such settings, and ports one use in resolved and another in networkd over to it.
2016-01-05networkd: link - do not drop config for critical interfacesDamjan Georgievski
the idea is that interfaces marked as critical are typically used for NFS root. networkd shouldn't drop that config. discussion at #780
2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

2015-11-17networkd: ndisc - consider configured on timeoutTom Gundersen
Don't block indefinitely, when control has been passed on from NDisc to DHCPv6. In this case there is likely no IPv6 support on the local link, so otherwise this would block indefinitely.
2015-11-17sd-dhcp6-client: bind to link-local addressTom Gundersen
This ensures that several DHCPv6 clients can run on separate interfaces simultaneously.

2015-11-17networkd: ndisc - always configure dhcp6 clientTom Gundersen
The ndisc client may trigger the dhcpv6 client to be started (this is the common case), so we should allocate the dhcpv6 client whenever we allocate the ndisc one.

2015-11-16siphash24: let siphash24_finalize() and siphash24() return the result directlyDaniel Mack
Rather than passing a pointer to return the result, return it directly from the function calls. Also, return the result in native endianess, and let the callers care about the conversion. For hash tables and bloom filters, we don't care, but in order to keep MAC addresses and DHCP client IDs stable, we explicitly convert to LE.

2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.

2015-11-13networkd: check explicit state rather than link->networkTom Gundersen
When deserializing we can now have an attached network without the various clients yet having been configured. Hence, don't misused the link->network as a check to determine if a link is ready to be used, but check the state explicitly.
