2016-01-28resolved: emit full path to file we failed to writeZbigniew Jędrzejewski-Szmek
Otherwise it's unclear if it's /etc/resolv.conf or some other file that is meant.
2016-01-26resolved: prorize rtnl and sd-network event sourcesLennart Poettering
Lets make sure we always take notice of network changes before answering client requests. This way, calls like SetLinkDNS() become race-free as the specified interface index is guarantee to have been processed if it exists before we make changes to it.
2016-01-25resolved: synthesize RRs for data from /etc/hostsLennart Poettering
This way the difference between lookups via NSS and our native bus API should become minimal.
2016-01-25resolved: log each time we increase the DNSSEC verdict countersLennart Poettering
Also, don't consider RRs that aren't primary to the lookups we do as relevant to the lookups.
2016-01-19resolved: rework DNSSECSupported propertyLennart Poettering
Not only report whether the server actually supports DNSSEC, but also first check whether DNSSEC is actually enabled for it in our local configuration. Also, export a per-link DNSSECSupported property in addition to the existing manager-wide property.
2016-01-11resolved: set a description on all our event sourcesLennart Poettering
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.
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.
2015-12-18resolved: use right format specifier to print transaction IDLennart Poettering
2015-12-08resolved: create dns scopes for mDNSDaniel Mack
Follow what LLMNR does, and create per-link DnsScope objects.
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.
2015-11-27tree-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.
2015-11-25dns-domain: rework dns_label_escape() to not imply memory allocationLennart Poettering
The new dns_label_escape() call now operates on a buffer passed in, similar to dns_label_unescape(). This should make decoding a bit faster, and nicer.
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: 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 FallbackDNS= overrides built-in servers, doesn't extend themLennart Poettering
Closes #342.
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: 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
2015-11-25resolved: /etc/resolved.conf missing is not an errorLennart Poettering
Don't propagate any error in this case, it's really not an error.
2015-11-23resolved: fix minor memory leak when shuttin downLennart Poettering
We need to free the rtnl watch too.
2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-27util-lib: move string table stuff into its own string-table.[ch]Lennart Poettering

2015-10-26util-lib: split out IO related calls to io-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-09-09tree-wide: make use of log_error_errno() return valueLennart Poettering
Turns this: r = -errno; log_error_errno(errno, "foo"); into this: r = log_error_errno(errno, "foo"); and this: r = log_error_errno(errno, "foo"); return r; into this: return log_error_errno(errno, "foo");
2015-08-26manager: close hostname fd *after* removing it epollLennart Poettering
Otherwise the epoll removal will fail and result in a warning.

2015-08-21remove unused variablesThomas Hindoe Paaboel Andersen
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.
2015-08-17Bug #944: Deletion of unnecessary checks before a few calls of systemd functionsMarkus Elfring
The following functions return immediately if a null pointer was passed. * calendar_spec_free * link_address_free * manager_free * sd_bus_unref * sd_journal_close * udev_monitor_unref * udev_unref It is therefore not needed that a function caller repeats a corresponding check. This issue was fixed by using the software Coccinelle 1.0.1.
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.
2015-07-27resolved: transaction - don't request PKTINFO for unicast DNSTom Gundersen
This was only ever used by LLMNR, so don't request this for unicast DNS packets.
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).
2015-07-14resolved: 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.
2015-07-13resolved: move LLMNR related functions into separate fileDaniel Mack

2015-06-10util: introduce CMSG_FOREACH() macro and make use of it everywhereLennart Poettering
It's only marginally shorter then the usual for() loop, but certainly more readable.
