2015-08-21resolved: rework synthesizing logicLennart Poettering
With this change we'll now also generate synthesized RRs for the local LLMNR hostname (first label of system hostname), the local mDNS hostname (first label of system hostname suffixed with .local), the "gateway" hostname and all the reverse PTRs. This hence takes over part of what nss-myhostname already implemented. Local hostnames resolve to the set of local IP addresses. Since the addresses are possibly on different interfaces it is necessary to change the internal DnsAnswer object to track per-RR interface indexes, and to change the bus API to always return the interface per-address rather than per-reply. This change also patches the existing clients for resolved accordingly (nss-resolve + systemd-resolve-host). This also changes the routing logic for queries slightly: we now ensure that the local hostname is never resolved via LLMNR, thus making it trustable on the local system.
2015-07-14resolved: reference count the dns serversTom Gundersen
We want to reference the servers from their active transactions, so make sure they stay around as long as the transaction does.

2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.
2014-08-14resolved: pull in domain names from sd-networkTom Gundersen
2014-08-14resolved: enable LLMNRLennart Poettering
THis was accidentally broken, as we truned off LLMNR far to frequently, where we only wanted to turn off LLMNr on IPV6 on kernels lacking support for it.
2014-08-13sd-network: /_get_link_/_link_get_/Tom Gundersen
The link is the 'object', so make this in line with our usual naming convention. Suggested by Kay and Lennart.
2014-08-13resolved: skip IPv6 LLMNR if IPv6 is not availableLennart Poettering
2014-08-11sd-network: rename the per-ifindex calls to sd_network_get_link_xxx()Lennart Poettering
This way we can introduce system-wide versions of these calls that are called the same way, but without the "link" in the name.
2014-08-05resolved: don't consider tentative addresses relevantLennart Poettering

2014-08-04resolved: read the per-interface LLMNR setting from networkd and act on itLennart Poettering
2014-08-01resolved: flush cache each time we change to a different DNS serverLennart Poettering
2014-08-01resolved: read the system /etc/resolv.conf unless we wrote it ourselvesLennart Poettering
This way we integrate nicely with foreign network management stacks, such as NM.
2014-08-01resolved: beef up DNS server configuration logicLennart Poettering
We now maintain two lists of DNS servers: system servers and fallback servers. system servers are used in combination with any per-link servers. fallback servers are only used if there are no system servers or per-link servers configured. The system server list is supposed to be populated from a foreign tool's /etc/resolv.conf (not implemented yet). Also adds a configuration switch for LLMNR, that allows configuring whether LLMNR shall be used simply for resolving or also for responding.

2014-07-29resolve: add llmnr responder side for UDP and TCPLennart Poettering
Name defending is still missing.
2014-07-23sd-network: expose DNS/NTP servers as stringsTom Gundersen
This avoids having to distinguish between IPv4 and IPv6, allowing us to keep their internal orderings. The consumers now has to turn the strings into addresses.
2014-07-23resolved: don't read DHCP leasesTom Gundersen
networkd will expose both statically configured DNS servers and servers receieved over DHCP in sd_network_get_dns(), so no need to keep the distinction in resolved.
2014-07-23networkd: merge DNS and NTP entries when exportingTom Gundersen
In the state files, do not distinguish where the various entries came from (static or DHCP), but include them all in the same list.
2014-07-18change type for address family to "int"Lennart Poettering
Let's settle on a single type for all address family values, even if UNIX is very inconsitent on the precise type otherwise. Given that socket() is the primary entrypoint for the sockets API, and that uses "int", and "int" is relatively simple and generic, we settle on "int" for this.
2014-07-18resolved: add LLMNR support for looking up namesLennart Poettering

2014-07-17sd-network: remove redundant array size parameter from functions that return ↵Lennart Poettering
arrays As long as the number of array entries is relatively small it's nicer to simply return the number of entries directly, instead of using a size_t* return parameter for it.

2014-07-16resolved: do not free() sd_dhcp_lease_get_dns() resultsKay Sievers
2014-07-16resolved: add a DNS client stub resolverLennart Poettering
Let's turn resolved into a something truly useful: a fully asynchronous DNS stub resolver that subscribes to network changes. (More to come: caching, LLMNR, mDNS/DNS-SD, DNSSEC, IDN, NSS module)
