2016-01-17resolved: fix logging about DNAME redirectionLennart Poettering
2016-01-17resolved: when we find a DNAME RR, don't insist in a signed CNAME RRLennart Poettering
If we have a signed DNAME RR response, there's no need to insist on a signature for a CNAME RR response, after all it is unlikely to be signed, given the implicit synthethis of CNAME through DNAME RRs.
2016-01-17Fix broken SYSTEMD_USER_WANTS in udev rules.Abdo Roig-Maranges
The functionality of SYSTEMD_USER_WANTS that attaches dependencies to device units from udev rules was broken since commit b2c23da8. I guess it was due to a mass replace s/SYSTEMD_USER/MANAGER_USER/.

2016-01-17resolved: update DNSSEC TODOLennart Poettering
2016-01-17resolved: try to reduce number or DnsResourceKeys we keep around by merging themLennart Poettering
Quite often we read the same RR key multiple times from the same message. Try to replace them by a single object when we notice this. Do so again when we add things to the cache. This should reduce memory consumption a tiny bit.
2016-01-17resolved: when switching between DNSSEC modes, possibly flush cachesLennart Poettering
If the networkd configuration changes during runtime, make sure to flush all caches when we switch from a less trusted to a more trusted mode.
2016-01-17resolved: when the server feature level changes between query and response ↵Lennart Poettering
restart transaction In some cases we learn something about a server's feature level through its responses. If we notice that after doing basic checking of a response, and after collecting all auxiliary DNSSEC info the feature level of the server is lower than where we started, restart the whole transaction. This is useful to deal with servers that response rubbish when talked to with too high feature levels.
2016-01-17resolved: check OPT RR before accepting a reply for verification of server ↵Lennart Poettering
feature level Let's make sure we first check if the OPT was lost in the reply, before we accept a reply as successful and use it for verifying the current feature level.
2016-01-17resolved: when restarting a DNS transaction, remove all auxiliary DNSSEC ↵Lennart Poettering
transactions When we restart a DNS transaction, remove all connections to any auxiliary DNSSEC transactions, after all we might acquire completely different data this time, requiring different auxiliary DNSSEC transactions.
2016-01-17resolved: when we receive an reply which is OPT-less or RRSIG-less, ↵Lennart Poettering
downgrade what we verified If we receive a reply that lacks the OPT RR, then this is reason to downgrade what was verified before, as it's apparently no longer true, and the previous OPT RR we saw was only superficially OK. Similar, if we realize that RRSIGs are not augmented, then also downgrade the feature level that was verified, as DNSSEC is after all not supported. This check is in particular necessary, as we might notice the fact that RRSIG is not augmented only very late, when verifying the root domain. Also, when verifying a successful response, actually take in consideration that it might have been reported already that RRSIG or OPT are missing in the response.
2016-01-17resolved: downgrade server feature level more aggressively when we have ↵Lennart Poettering
reason to This adds logic to downgrade the feature level more aggressively when we have reason to. Specifically: - When we get a response packet that lacks an OPT RR for a query that had it. If so, downgrade immediately to UDP mode, i.e. don't generate EDNS0 packets anymore. - When we get a response which we are sure should be signed, but lacks RRSIG RRs, we downgrade to EDNS0 mode, i.e. below DO mode, since DO is apparently not really supported. This should increase compatibility with servers that generate non-sensical responses if they messages with OPT RRs and suchlike, for example the situation described here: https://open.nlnetlabs.nl/pipermail/dnssec-trigger/2014-November/000376.html This also changes the downgrade code to explain in a debug log message why a specific downgrade happened.
2016-01-17resolved: ignore invalid OPT RRs in incoming packetsLennart Poettering
This validates OPT RRs more rigorously, before honouring them: if we any of the following condition holds, we'll ignore them: a) Multiple OPT RRs in the same message b) OPT RR not owned by the root domain c) OPT RR in the wrong section (Belkin routers do this) d) OPT RR contain rfc6975 algorithm data (Belkin routers do this) e) OPT version is not 0 f) OPT payload doesn't add up with the lengths Note that d) may be an indication that the server just blindly copied OPT data from the response into the reply. RFC6975 data is only supposed to be included in queries, and we do so. It's not supposed to be included in responses (and the RFC is very clear on that). Hence if we get it back in a reply, then the server probably just copied the OPT RR.
2016-01-17resolved: update RFCs list and TODO listLennart Poettering
2016-01-17resolved: add complex test caseLennart Poettering
This new test case tries to resolve a couple of known domains, to verify the validation results. It talks to resolved via the bus, thus comprehensively testing the whole shebang. Of course, it requires network connectivity and a DNSSEC capable DNS server, hence this is a manual test.
2016-01-17resolved: complete NSEC non-existance proofsLennart Poettering
This fills in the last few gaps: - When checking if a domain is non-existing, also check that no wildcard for it exists - Ensure we don't base "covering" tests on NSEC RRs from a parent zone - Refuse to accept expanded wildcard NSEC RRs for absence proofs.
2016-01-17resolved: make sure the NSEC proof-of-non-existance check also looks for ↵Lennart Poettering
wildcard domains
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.
2016-01-17resolved: ignore DS RRs without generating an error if they use an ↵Lennart Poettering
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
