2015-11-25util-lib: add ordered_set_ensure_allocated()Lennart Poettering
ordered_set_ensure_allocated() does for an OrderedSet, what set_ensure_allicated() does for a Set.
2015-11-25resolved: enforce a maximum limit on both dns servers and search domainsLennart Poettering
2015-11-25resolved: unify DnsServer handling code between Link and ManagerLennart Poettering
This copies concepts we introduced for the DnsSearchDomain stuff, and reworks the operations on lists of dns servers to be reusable and generic for use both with the Link and the Manager object.
2015-11-25resolved: add a generic DnsSearchDomain conceptLennart Poettering
With this change, we add a new object to resolved, "DnsSearchDomain=" which wraps a search domain. This is then used to introduce a global search domain list, in addition to the existing per-link search domain list which is reword to make use of this new object too. This is preparation for implement proper unicast DNS search domain support.
2015-11-25resolved: make sure order of dns servers is stableLennart Poettering
Previously, we'd keep adding new dns servers we discover to the end of our linked list of servers. When we encountered a pre-existing server, we'd just leave it where it was. In essence that meant that old servers ended up at the front, and new servers at the end, but not in an order that would reflect the configuration. With this change we ensure that every pre-existing server we want to add again we move to the back of the linked list, so that the order is stable and in sync with the requested configuration.

2015-11-25resolved: rework dns server lifecycle logicLennart Poettering
Previously, there was a chance of memory corruption, because when switching to the next DNS server we didn't care whether they linked list of DNS servers was still valid. Clean up lifecycle of the dns server logic: - When a DnsServer object is still in the linked list of DnsServers for a link or the manager, indicate so with a "linked" boolean field, and never follow the linked list if that boolean is not set. - When picking a DnsServer to use for a link ot manager, always explicitly take a reference. This also rearranges some logic, to make the tracking of dns servers by link and globally more alike.

2015-11-25resolved: split out all code dealing with /etc/resolv.conf into its own .c fileLennart Poettering
No functional changes.
2015-11-25resolved: unify code for parsing dns server informationLennart Poettering
Let's use the same parser when parsing dns server information from /etc/resolv.conf and our native configuration file. Also, move all code that manages lists of dns servers to a single place. resolved-dns-server.c
2015-11-25resolved: /etc/resolved.conf missing is not an errorLennart Poettering
Don't propagate any error in this case, it's really not an error.
2015-11-25dns-domain: remove prototype for function that doesn't existLennart Poettering
2015-11-25man: fix documentation how /etc/resolv.conf is readLennart Poettering
/etc/resolv.conf is only read when the DNS= setting does not appear at all in resolved.conf, regardless if set to the empty list or anything else. Correct that in the man page.
2015-11-25resolved: don't claim DnsQuestion have to have the same namesLennart Poettering
Wen DnsQuestion objects are used for DnsQuery objects all contained keys have to share the same name, but otherwise they generally don't have to, and this can actually happen in real-life because DnsPacket objects for mDNS use DnsQuestion for the question section. Hence, rename: dns_question_is_valid() to dns_question_is_valid_for_query(), since the name uniqueness check it does is only relevant when used for a query. Similar, rename dns_question_name() to dns_question_first_name(), to be more accurate, as this difference matters if we keys don#t have to share the same name.

FOREACH_WORD_SEPARATOR is no need here since we only apply only one mount flag. The rvalue is sufficient for this.

Most servers apparently always implicitly convert DNAME to CNAME, but some servers don't, hence implement this properly, as this is required by edns0.

resolved: add support for resolving plain SRV and DNS-SD services
2015-11-23resolved: add ResolveService() bus call for resolving SRV and DNS-SD servicesLennart Poettering
This also adds client-side support for this to systemd-resolve-host. Note that the ResolveService() API can deal both with DNS-SD service (consisting of service name, type and domain), as well as classic SRV services (consisting just of a type and a domain), all exposed in the same call. This patch also reworks CNAME handling in order to reuse it between hostname, RR and service lookups. In contrast to Avahi and Bonjour, this new API will actually reolve the A/AAAA RRs the SRV RRs point to in one go (unless this is explicitly disabled). This normally comes for free, as these RRs are sent along the SRV responses anyway, hence let's make use of that. This makes the API considerably easier to use, as a single ResolveService() invocation will return all necessary data to pick a server and connect() to it. Note that this only implements the DNS-SD resolving step, it does not implement DNS-SD browsing, as that makes sense primarily on mDNS, due to its continuous nature.

We need to free the rtnl watch too.
2015-11-23dns-domain: add calls to join/split SRV/DNS-SD service domainsLennart Poettering
This adds dns_service_join() and dns_service_split() which may be used to concatenate a DNS-SD service name, am SRV service type string, and a domain name into a full resolvable DNS domain name string. If the service name is specified as NULL, only the type and domain are appended, to implement classic, non-DNS-SD SRV lookups. The reverse is dns_service_split() which takes the full name, and split it into the three components again.

2015-11-23resolved: accept TXT records with non-UTF8 stringsLennart Poettering
RFC 6763 is very clear that TXT RRs should allow arbitrary binary content, hence let's actually accept that. This also means accepting NUL bytes in the middle of strings.
