2016-01-05resolved,networkd: add a per-interface DNSSEC settingLennart Poettering
This adds a DNSSEC= setting to .network files, and makes resolved honour them.
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.
2015-12-26resolved: gather statistics about resolved namesLennart Poettering
This collects statistical data about transactions, dnssec verifications and the cache, and exposes it over the bus. The systemd-resolve-host tool learns new options to query these statistics and reset them.
2015-12-08resolved: add infrastructure for mDNS related socketsDaniel Mack
Just hook up mDNS listeners with an empty packet dispather function, introduce a config directive, man page updates etc.
2015-12-03resolved: add a simple trust anchor database as additional RR sourceLennart Poettering
When doing DNSSEC lookups we need to know one or more DS or DNSKEY RRs as trust anchors to validate lookups. With this change we add a compiled-in trust anchor database, serving the root DS key as of today, retrieved from: https://data.iana.org/root-anchors/root-anchors.xml The interface is kept generic, so that additional DS or DNSKEY RRs may be served via the same interface, for example by provisioning them locally in external files to support "islands" of security. The trust anchor database becomes the fourth source of RRs we maintain, besides, the network, the local cache, and the local zone.
2015-11-25resolved: split out calls to compile full list of dns servers and search domainsLennart Poettering
Let's split this out from the resolv.conf parser, so that this becomes generically useful.
2015-11-25resolved: enforce a maximum limit on both dns servers and search domainsLennart Poettering
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 FallbackDNS= overrides built-in servers, doesn't extend themLennart Poettering
Closes #342.
2015-11-25resolved: move dns server picking code from resolved-manager.c to ↵Lennart Poettering
resolved-dns-server.c
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
2015-11-18tree-wide: sort includes in *.hThomas Hindoe Paaboel Andersen
This is a continuation of the previous include sort patch, which only sorted for .c files.
2015-08-26resolved: dump cache and zone contents to syslog on SIGUSR1Lennart Poettering
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.
2015-07-27resolved: scope - write() unicast DNS packetsTom Gundersen
As we have connect()ed to the desired DNS server, we no longer need to pass control messages manually when sending packets. Simplify the logic accordingly.
2015-07-14resolved: use one UDP socket per transactionTom Gundersen
We used to have one global socket, use one per transaction instead. This has the side-effect of giving us a random UDP port per transaction, and hence increasing the entropy and making cache poisoining significantly harder to achieve. We still reuse the same port number for packets belonging to the same transaction (resent packets).
2015-07-13resolved: move LLMNR related functions into separate fileDaniel Mack
2015-06-13sd-netlink: rename from sd-rtnlTom Gundersen
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2014-10-22resolved: simplify detection of packets from the loopback deviceLennart Poettering
We can simplify our code quite a bit if we explicitly check for the ifindex being 1 on Linux as a loopback check. Apparently, this is hardcoded on Linux on the kernel, and effectively exported to userspace via rtnl and such, hence we should be able to rely on it.
2014-08-12resolved: unify logic how we flush out DNS servers we learntLennart Poettering
2014-08-11resolved: verify all RRs when we come back from suspendLennart Poettering
2014-08-11resolved: implement full LLMNR conflict detection logicLennart Poettering
2014-08-04resolved: read the per-interface LLMNR setting from networkd and act on itLennart Poettering
2014-08-04resolved: when there's already somebody listening on the LLMNR ports, simple ↵Lennart Poettering
disable LLMNR and warn, but continue This allows us to run resolved inside an nspawn container that shares the network namespace with the host, if there's already an instance running.
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: rename resolved.h to resolved-manager.hLennart Poettering
After all it pretty much exlcusively containers definitions about the "Manager" object, hence let's call this the most obvious way.
