We really shouldn't make up errors like "-1", but use proper errno definitions.
2016-06-24fstab-generator: fix checking of fstab_node_to_udev_node() resultLennart Poettering
We have to check for OOM here, let's add that. There's really no point in checking for path_is_absolute() on the result however, as there's no particular reason why that should be refused. Also, we don't have similar checks for the other mount devices the generator deals with, hence don't bother with it here either. Let's remove that check. (And it shouldn't return made-up errors like "-1" in this case anyway.)

2016-06-24resolved: add option to disable caching (#3592)Martin Pitt
In some cases, caching DNS results locally is not desirable, a it makes DNS cache poisoning attacks a tad easier and also allows users on the system to determine whether or not a particular domain got visited by another user. Thus provide a new "Cache" resolved.conf option to disable it.

2016-06-23resolved: when processing auxiliary DNSSEC transactions, accept those with ↵Lennart Poettering
SERVFAIL Some upstream DNS servers return SERVFAIL if we ask them for DNSSEC RRs, which some forwarding DNS servers pass on to us as SERVFAIL (other though as NOERROR...). This is should not be considered a problem, as long as the domain in question didn't have DNSSEC enabled. Hence: when making use of auxiliary transactions accept those that return SERVFAIL.
2016-06-23resolved: when caching replies, check rcode earlierLennart Poettering
This way we don't log complaints about packets without SOA in case we are not caching it anyway because the rcode is not SUCCESS or NXDOMAIN...
2016-06-23resolved: rework SERVFAIL handlingLennart Poettering
There might be two reasons why we get a SERVFAIL response from our selected DNS server: because this DNS server itself is bad, or because the DNS server actually serving the zone upstream is bad. So far we immediately downgraded our server feature level when getting SERVFAIL, under the assumption that the first case is the only possible case. However, this meant we'd downgrade immediately even if we encountered the second case described above. With this commit handling of SERVFAIL is reworked. As soon as we get a SERVFAIL on a transaction we retry the transaction with a lower feature level, without changing the feature level tracked for the DNS server itself. If that fails too, we downgrade further, and so on. If during this downgrading the SERVFAIL goes away we assume that the DNS server we are talking to is bad, but the zone is fine and propagate the detected feature level to the information we track about the DNS server. Should the SERVFAIL not go away this way we let the transaction fail and accept the SERVFAIL.

2016-06-23build-sys: move fdset.[ch] src/basic → src/shared (#3580)Lennart Poettering
It makes use of the sd_listen_fds() call, and as such should live in src/shared, as the distinction between src/basic and src/shared is that the latter may use libsystemd APIs, the former does not. Note that btrfs-util.[ch] and log.[ch] also include header files from libsystemd, but they only need definitions, they do not invoke any function from it. Hence they may stay in src/basic.
2016-06-23execute: add a new easy-to-use RestrictRealtime= option to unitsLennart Poettering
It takes a boolean value. If true, access to SCHED_RR, SCHED_FIFO and SCHED_DEADLINE is blocked, which my be used to lock up the system.

2016-06-22watchdog: Support changing watchdog_usec during runtime (#3492)Minkyung
Add sd_notify() parameter to change watchdog_usec during runtime. Application can change watchdog_usec value by sd_notify like this. Example. sd_notify(0, "WATCHDOG_USEC=20000000"). To reset watchdog_usec as configured value in service file, restart service. Notice. sd_event is not currently supported. If application uses sd_event_set_watchdog, or sd_watchdog_enabled, do not use "WATCHDOG_USEC" option through sd_notify.

2016-06-22pid1: initialize TERM environment variable correctlyFranck Bui
When systemd is started by the kernel, the kernel set the TERM environment variable unconditionnally to "linux" no matter the console device used. This might be an issue for dumb devices with no colors support. This patch uses default_term_for_tty() for getting a more accurate value. But it makes sure to keep the user preferences (if any) which might be passed via the kernel command line. For that purpose /proc should be mounted.
2016-06-21machinectl: interpret options placed between "shell" verb and machine nameLennart Poettering

2016-06-21resolved: respond to local resolver requests on 127.0.0.53:53Lennart Poettering
In order to improve compatibility with local clients that speak DNS directly (and do not use NSS or our bus API) listen locally on 127.0.0.53:53 and process any queries made that way. Note that resolved does not implement a full DNS server on this port, but simply enough to allow normal, local clients to resolve RRs through resolved. Specifically it does not implement queries without the RD bit set (these are requests where recursive lookups are explicitly disabled), and neither queries with DNSSEC DO set in combination with DNSSEC CD (i.e. DNSSEC lookups with validation turned off). It also refuses zone transfers and obsolete RR types. All lookups done this way will be rejected with a clean error code, so that the client side can repeat the query with a reduced feature set. The code will set the DNSSEC AD flag however, depending on whether the data resolved has been validated (or comes from a local, trusted source). Lookups made via this mechanisms are propagated to LLMNR and mDNS as necessary, but this is only partially useful as DNS packets cannot carry IP scope data (i.e. the ifindex), and hence link-local addresses returned cannot be used properly (and given that LLMNR/mDNS are mostly about link-local communication this is quite a limitation). Also, given that DNS tends to use IDNA for non-ASCII names, while LLMNR/mDNS uses UTF-8 lookups cannot be mapped 1:1. In general this should improve compatibility with clients bypassing NSS but it is highly recommended for clients to instead use NSS or our native bus API. This patch also beefs up the DnsStream logic, as it reuses the code for local TCP listening. DnsStream now provides proper reference counting for its objects. In order to avoid feedback loops resolved will no silently ignore 127.0.0.53 specified as DNS server when reading configuration. resolved listens on 127.0.0.53:53 instead of 127.0.0.1:53 in order to leave the latter free for local, external DNS servers or forwarders. This also changes the "etc.conf" tmpfiles snippet to create a symlink from /etc/resolv.conf to /usr/lib/systemd/resolv.conf by default, thus making this stub the default mode of operation if /etc is not populated.

2016-06-21resolved: when using the ResolveRecord() bus call, adjust TTL for caching timeLennart Poettering
When we return the full RR wire data, let's make sure the TTL included in it is adjusted by the time the RR sat in the cache. As an optimization we do this only for ResolveRecord() and not for ResolveHostname() and friends, since adjusting the TTL means copying the RR object, and we don#t want to do that if there's no reason to. (ResolveHostname() and friends don't return the TTL hence there's no reason to in that case)

2016-06-21sd-bus: make sure bus_map_all_properties() handle booleans rightLennart Poettering
sd-bus generally exposes bools as "int" instead of "bool" in the public API. This is relevant when unmarshaling booleans, as the relevant functions expect an int* pointer and no bool* pointer. Since sizeof(bool) is not necessarily the same as sizeof(int) this is problematic and might result in memory corruption. Let's fix this, and make sure bus_map_all_properties() handles booleans as ints, as the rest of sd-bus, and make all users of it expect the right thing.
