2016-06-14resolved: in the ResolveHostname() bus call, accept IP addresses with scopeLennart Poettering
When we get a literal IP address as string that includes a zone suffix, process this properly and return the parsed ifindex back to the client, and include it in the canonical name in case of a link-local IP address.
2016-06-14resolved: make sure we initialize the ifindex of direct zone answers properlyLennart Poettering
Previously, after checking the local zone for a reply and finding one we'd not initialize the answer ifindex from that. Let's fix that.
2016-06-14resolve: port resolve tool to in_addr_ifindex_{from_string_auto|to_string}()Lennart Poettering
We can reuse some code here, so let's do it.
2016-06-13resolved: use single message for both dbus and signal calls (#3515)Zbigniew Jędrzejewski-Szmek
Follow-up for #3502.
2016-06-10resolved: move verification that link is unmanaged into the proper bus callsLennart Poettering
Previously, we checked only for the various SetLinkXYZ() calls on the Manager object exposed on the bus if the specified interface is managed/unmanaged by networkd (as we don't permit overriding DNS configuration via bus calls if networkd owns the device), but the equivalent SetXYZ() calls on the Link object did not have such a check. Fix that by moving the appropriate check into the latter, as the former just calls that anyway.
2016-06-10resolved: also add a way to flush all caches via the busLennart Poettering
And expose it in "resolve-tool --flush-caches".

2016-06-06resolved: also rewrite private /etc/resolv.conf when configuration is ↵Lennart Poettering
changed via bus calls This also moves log message generation into manager_write_resolv_conf(), so that it is shorter to invoke the function, given that we have to invoke it at a couple of additional places now. Fixes: #3225
2016-06-06resolved: support IPv6 DNS servers on the local linkLennart Poettering
Make sure we can parse DNS server addresses that use the "zone id" syntax for local link addresses, i.e. "fe80::c256:27ff:febb:12f%wlp3s0", when reading /etc/resolv.conf. Also make sure we spit this out correctly again when writing /etc/resolv.conf and via the bus. Fixes: #3359

2016-06-03resolved: fix comments in resolve.conf for search domain overflows (#3422)Martin Pitt
Write comments about "too many search domains" and "Total length of all search domains is too long" just once. Also put it on a separate line, as resolv.conf(5) only specifies comments in a line by themselves. This is ugly to do if write_resolv_conf_search() gets called once for every search domain. So change it to receive the complete OrderedSet instead and do the iteration by itself. Add test cases to networkd-test.py. https://launchpad.net/bugs/1588229

2016-05-02resolved: work around broken DNS zones set up by incapdns.netLennart Poettering
incapdns.net returns NXDOMAIN for the SOA of the zone itself but is not a terminal. This is against the specs, but we really should be able to deal with this. Previously, when verifying whether an NXDOMAIN response for a SOA/NS lookup is rightfully unsigned we'd issue a SOA lookup for the parent's domain, to derive the state from that. If the parent SOA would get an NXDOMAIN, we'd continue upwards, until we hit a signed top-level domain, which suggests that the domain actually exists. With this change whenver we need to authenticate an NXDOMAIN SOA reply, we'll request the DS RR for the zone first, and use for validation, since that this must be from the parent's zone, not the incorrect lower zone. Fixes: #2894

2016-04-12Do not report masked units as changed (#2921)Zbigniew Jędrzejewski-Szmek
* core/unit: extract checking of stat paths into helper function The same code was repeated three times. * core: treat masked files as "unchanged" systemctl prints the "unit file changed on disk" warning for a masked unit. I think it's better to print nothing in that case. When a masked unit is loaded, set mtime as 0. When checking if a unit with mtime of 0 needs reload, check that the mask is still in place. * test-dnssec: fix build without gcrypt Also reorder the test functions to follow the way they are called from main().

2016-02-22resolved: fix notification iteration logic when transactions are completedLennart Poettering
When a transaction is complete, and we notify its owners, make sure we deal correctly with the requesters removing themselves from the list of owners while we continue iterating. This was previously already dealt with with transactions that require other transactions for DNSSEC purposes, fix this for other possibly transaction owners too now. Since iterating through "Set" objects is not safe regarding removal of entries from it, rework the logic to use two Sets, and move each entry we notified from one set to the other set before we dispatch the notification. This move operation requires no additional memory, and enables us to ensure that we don't notify any object twice. Fixes: #2676
2016-02-20tree-wide: place #pragma once at the same place everywhereLennart Poettering
Usually, we place the #pragma once before the copyright blurb in header files, but in a few cases we didn't. Move those around, so that we do the same thing everywhere.

2016-02-16Use provided buffer in dns_resource_key_to_stringZbigniew Jędrzejewski-Szmek
When the buffer is allocated on the stack we do not have to check for failure everywhere. This is especially useful in debug statements, because we can put dns_resource_key_to_string() call in the debug statement, and we do not need a seperate if (log_level >= LOG_DEBUG) for the conversion. dns_resource_key_to_string() is changed not to provide any whitespace padding. Most callers were stripping the whitespace with strstrip(), and it did not look to well anyway. systemd-resolve output is not column aligned anymore. The result of the conversion is not stored in DnsTransaction object anymore. It is used only for debugging, so it seems fine to generate it when needed. Various debug statements are extended to provide more information.
