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: rename dnssec_verify_dnskey() → dnssec_verify_dnskey_by_ds()Lennart Poettering
This should clarify that this is not regular signature-based validation, but validation through DS RR fingerprints.
2016-01-17resolved: be stricter when using NSEC3Lennart Poettering
We can user signer and synthesizing source information to check that the NSEC3 RRs we want to use are actually reasonable and properly signed.
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.
2016-01-17resolved: do not use NSEC RRs from the wrong zone for proofsLennart Poettering
When proving NODATA DS lookups we need to insist on looking at the parent zone's NSEC RR, not the child zone's. When proving any other NODATA lookups we need to insist on looking at the child zone's NSEC RR, not the parent's.

unsupported digest algorithm
2016-01-17resolved: some RR types may appear only or not at all in a zone apexLennart Poettering
Add extra checks when validating with RRSIGs. This follows recommendations from: http://www.george-barwood.pwp.blueyonder.co.uk/DnsServer/NotesOnDNSSSEC.htm

2016-01-14transaction: downgrade warnings about wanted unit which are not foundFranck Bui
If a unit was pulled by a Wants= dependency but its unit file was not present then we logged this as an error. However Wants= might be used to configure a soft/optional dependency on another unit, ie. start an optional service only if it's installed otherwise simply skip it. In this case emitting an error doesn't look appropriate. But it's still an error if the optional dependency exists but its activation fails for any reasons.

2016-01-13resolved: properly handles RRs in domains beginning in an asterisk labelLennart Poettering
Properly handle RRs that begin with an asterisk label. These are the unexpanded forms of wildcard domains and appear in NSEC RRs for example. We need to make sure we handle the signatures of these RRs properly, since they mostly are considered normal RRs, except that the RRSIG labels counter is one off for them, as the asterisk label is always excluded of the signature.

2016-01-12sd-event: instrument sd_event_run() for profiling delaysVito Caputo
Set SD_EVENT_PROFILE_DELAYS to activate accounting and periodic logging of the distribution of delays between sd_event_run() calls. Time spent in dispatching as well as time spent outside of sd_event_run() is measured and accounted for. Every 5 seconds a logarithmic histogram loop iteration delays since 5 seconds previous is logged. This is useful in identifying the frequency and magnitude of latencies affecting the event loop, which should be kept to a minimum.
