2016-02-15systemctl: include -M or -H arguments in the hintZbigniew Jędrzejewski-Szmek
https://github.com/systemd/systemd/issues/2431 Some newlines are added, but the output will still exceed 80 columns in many cases. The fallback for oom conditions is changed from "n/a" to something "<service>", and a similar pattern is used for the new code. This way we have a realistic fallback for oom, which seems nicer than making the whole function return an error code which would then have to be propagated. $ systemctl -M fedora-rawhide restart systemd-networkd.service Job for systemd-networkd.service failed because start of the service was attempted too often. See "systemctl -M fedora-rawhide status systemd-networkd.service" and "journalctl -M fedora-rawhide -xe" for details. To force a start use "systemctl -M fedora-rawhide reset-failed systemd-networkd.service" followed by "systemctl -M fedora-rawhide start systemd-networkd.service" again.

2016-02-11Move initialize_libgcrypt to separate fileZbigniew Jędrzejewski-Szmek
It's annoying to have the exact same function in three places. It's stored in src/shared, but it's not added to the library to avoid the dependency on libgcrypt.

2016-02-01core: rework unit timeout handling, and add new setting RuntimeMaxSec=Lennart Poettering
This clean-ups timeout handling in PID 1. Specifically, instead of storing 0 in internal timeout variables as indication for a disabled timeout, use USEC_INFINITY which is in-line with how we do this in the rest of our code (following the logic that 0 means "no", and USEC_INFINITY means "never"). This also replace all usec_t additions with invocations to usec_add(), so that USEC_INFINITY is properly propagated, and sd-event considers it has indication for turning off the event source. This also alters the deserialization of the units to restart timeouts from the time they were originally started from. Before this patch timeouts would be restarted beginning with the time of the deserialization, which could lead to artificially prolonged timeouts if a daemon reload took place. Finally, a new RuntimeMaxSec= setting is introduced for service units, that specifies a maximum runtime after which a specific service is forcibly terminated. This is useful to put time limits on time-intensive processing jobs. This also simplifies the various xyz_spawn() calls of the various types in that explicit distruction of the timers is removed, as that is done anyway by the state change handlers, and a state change is always done when the xyz_spawn() calls fail. Fixes: #2249
2016-02-01core: fix support for transient resource limit propertiesLennart Poettering
Make sure we can properly process resource limit properties. Specifically, allow transient configuration of both the soft and hard limit, the same way from the unit files. Previously, only the the hard rlimits could be configured but they'd implicitly spill into the soft hard rlimits. This also updates the client-side code to be able to parse hard/soft resource limit specifications. Since we need to serialize two properties in bus_append_unit_property_assignment() now, the marshalling of the container around it is now moved into the function itself. This has the benefit of shortening the calling code. As a side effect this now beefs up the rlimit parser of "systemctl set-property" to understand time and disk sizes where that's appropriate.

2016-02-01core: fix handling of AccuracyUSec and RandomDelayUSec bus propertiesLennart Poettering
Clear up some confusion regarding the USec and Sec suffixes we use. In configuration files we usually use the Sec suffix, to indicate the implied time unit if none is specified. The respective bus properties however use the USec property, since they expose 64bit unsigned integers containing time in µs. Before this patch timer units exposed a bus property AccuracyUSec (which hence is the correct name) but when parsing transient property data would look for AccuracySec instead (which is incorrect). This patch ensures we look for AccuracySec correctly, but keeps the code for AccuracyUSec in place for compatibility, but adds a warning to ensure that apps are updated to use the right property.

2016-01-26shared: normalize the root domain to "." rather than ""Lennart Poettering
Let's make sure the root domain is normalized to ".", rather than then empty string, so that there's actually something to see on screen. Normally, we don't append a trailing dot to normalized domain names, but do so in the one exception of the root domain, taking inspiration from UNIX file system paths.

2016-01-18resolved: rework IDNA logicLennart Poettering
Move IDNA logic out of the normal domain name processing, and into the bus frontend calls. Previously whenever comparing two domain names we'd implicitly do IDNA conversion so that "pöttering.de" and "xn--pttering-n4a.de" would be considered equal. This is problematic not only for DNSSEC, but actually also against he IDNA specs. Moreover it creates problems when encoding DNS-SD services in classic DNS. There, the specification suggests using UTF8 encoding for the actual service name, but apply IDNA encoding to the domain suffix. With this change IDNA conversion is done only: - When the user passes a non-ASCII hostname when resolving a host name using ResolveHostname() - When the user passes a non-ASCII domain suffix when resolving a service using ResolveService() No IDNA encoding is done anymore: - When the user does raw ResolveRecord() RR resolving - On the service part of a DNS-SD service name Previously, IDNA encoding was done when serializing names into packets, at a point where information whether something is a label that needs IDNA encoding or not was not available, but at a point whether it was known whether to generate a classic DNS packet (where IDNA applies), or an mDNS/LLMNR packet (where IDNA does not apply, and UTF8 is used instead for all host names). With this change each DnsQuery object will now maintain two copies of the DnsQuestion to ask: one encoded in IDNA for use with classic DNS, and one encoded in UTF8 for use with LLMNR and MulticastDNS.

2016-01-18Use negative_errno() to assert errno is positive after a few system callsZbigniew Jędrzejewski-Szmek
This is not particularly intrusive because it happens in simple utility functions. It helps gcc understand that error codes are negative. This gets a rid of most of the remaining warnings.
2016-01-17resolved: on negative NODATA replies, properly deal with empty non-terminalsLennart Poettering
empty non-terminals generally lack NSEC RRs, which means we can deduce their existance only from the fact that there are other RRs that contain them in their suffix. Specifically, the NSEC proof for NODATA on ENTs works by sending the NSEC whose next name is a suffix of the queried name to the client. Use this information properly.
2016-01-17resolved: when validating an RRset, store information about the synthesizing ↵Lennart Poettering
source and zone in each RR Having this information available is useful when we need to check whether various RRs are suitable for proofs. This information is stored in the RRs as number of labels to skip from the beginning of the owner name to reach the synthesizing source/signer. Simple accessor calls are then added to retrieve the signer/source from the RR using this information. This also moves validation of a a number of RRSIG parameters into a new call dnssec_rrsig_prepare() that as side-effect initializes the two numeric values.

2015-12-13journal: properly handle an unexpectedly missing fieldZbigniew Jędrzejewski-Szmek
parse_field() checks if the field has the expected format, and returns 0 if it doesn't. In that case, value and size are not set. Nevertheless, we would try to continue, and hit an assert in safe_atou64. This case shouldn't happen, unless sd_j_get_data is borked, so cleanly assert that we got the expected field. Also, oom is the only way that parse_field can fail, which we log already. Instead of outputting a debug statement and carrying on, treat oom as fatal.
