Fixes to NSEC3 proof v2
2016-01-03Merge pull request #2256 from poettering/dnssec10Tom Gundersen
Tenth DNSSEC patch set
2016-01-03resolve: add RFC4501 URI support to systemd-resolve-hostLennart Poettering
2016-01-03resolved: add negative trust anchro support, and add trust anchor ↵Lennart Poettering
configuration files This adds negative trust anchor support and allows reading trust anchor data from disk, from files /etc/systemd/dnssec-trust-anchors.d/*.positive and /etc/systemd/dnssec-trust-anchros.d/*.negative, as well as the matching counterparts in /usr/lib and /run. The positive trust anchor files are more or less compatible to normal DNS zone files containing DNSKEY and DS RRs. The negative trust anchor files contain only new-line separated hostnames for which to require no signing. By default no trust anchor files are installed, in which case the compiled-in root domain DS RR is used, as before. As soon as at least one positive root anchor for the root is defined via trust anchor files this buil-in DS RR is not added though.
2016-01-03resolved: dnssec - properly take wildcards into account in NESC3 proofTom Gundersen
For NXDOMAIN, it is not sufficient to prove that the next-closest enclosure does not exist, we must also prove that there is no wildcard domain directly below the closest enclosure which would synthesise the name that has been requested. For positive responses, in addition to exact matches, we should accept wildcard ones. In that case we must first prove that there is no precise match (i.e., that the closest encounter is not the record itself) and secondly that the source of synthesis exists.
2016-01-03resolved: dnssec - factor out hashed domain generationTom Gundersen
2016-01-03resolved: don't conclude NODATA if CNAME existsTom Gundersen
Instead introduce the new return-code DNSSEC_NSEC_CNAME to indicate this condition. See RFC 6840, Section 4.3.
2016-01-02resolved: fix serialization of the root domainLennart Poettering
2016-01-02resolved: only suffix RR key names with a dot if they don't have one yetLennart Poettering

2016-01-02resolved: extend RFCs list a bitLennart Poettering
2016-01-01resolved: dnssec - add reference to the algorithm we implementTom Gundersen
2016-01-01resolved: dnssec - prepend hashed labels to zone nameTom Gundersen
All hashed names consist of the hashed label prepended to the zone name, not to the closest enclosure.
2016-01-01resolved: dnssec - rename some variablesTom Gundersen
Makes the NSEC3 proof somewhat simpler to follow.
2016-01-01resoled: dnssec - don't refuse to verify answer due to too many unrelated RRsTom Gundersen
Let VERIFY_RRS_MAX be about the max number of RRs in an RRSet that we actually try to verify, not about the total number of RRs in the RRSet.
2016-01-01resolved: dnssec - fix off-by-one in RSA key parsingTom Gundersen
If the first byte of the key is zero, the key-length is stored in the second and third byte (not first and second).

2015-12-29resolved: append RFC6975 algorithm data to EDNS OPT RRLennart Poettering
2015-12-29resolved: NSEC3 hash algorithms are distinct from DS digest algorithmsLennart Poettering
Previously, we'd use the same set of identifiers for both, but that's actually incorrect. It didn't matter much since the only NSEC3 hash algorithm defined (SHA-1) is mapped to code 1 which is also what it is encoded as in DS digests, but we really should make sure to use two distinct enumerations.

2015-12-29resolved: add comments referencing various RFCs to various placesLennart Poettering
2015-12-29resolved: include GOST in list of DNSSEC algorithmsLennart Poettering
We don't implement it, and we have no intention to, but at least mention that it exists. (This also adds a couple of other algorithms to the algorithm string list, where these strings were missing previously.)
2015-12-29resolved: use CLAMP() intsead of MIN(MAX())Lennart Poettering

2015-12-29resolved: reset RR TTL to 0, if MSB is setLennart Poettering
RFC 2181, Section 8 suggests to treat an RR TTL with the MSB set as 0. Implement this.
2015-12-29resolved: properly handle SRV RRs with the DNS root as hostnameLennart Poettering
2015-12-29resolved: add errno mapping for BUS_ERROR_CONNECTION_FAILURELennart Poettering
This was missing when the error type was added in ac720200b7e5b80cc4985087e38f3452e5b3b080.
2015-12-29resolved: change mapping of BUS_ERROR_NO_NAME_SERVERS to ESRCHLennart Poettering
EIO is really too generic, and indicates transmission problems.

Eigth DNSSEC patch set
2015-12-28resolved: update DNSSEC TODOLennart Poettering
2015-12-28resolved: also use RRSIG expiry for negative cachingLennart Poettering
This makes sure that we also honour the RRSIG expiry for negative caching.
2015-12-28resolved: use RRSIG expiry and original TTL for cache managementLennart Poettering
When we verified a signature, fix up the RR's TTL to the original TTL mentioned in the signature, and store the signature expiry information in the RR, too. Then, use that when adding RRs to the cache.
2015-12-28resolved: clean up dns_transaction_stop()Lennart Poettering
This renames dns_transaction_stop() to dns_transaction_stop_timeout() and makes it only about stopping the transaction timeout. This is safe, as in most occasions we call dns_transaction_stop() at the same time as dns_transaction_close_connection() anyway, which does the rest of what dns_transaction_stop() used to do. And in the one where we don't call it, it's implicitly called by the UDP emission or TCP connection code. This also closes the connections as we enter the validation phase of a transaction, so that no further messages may be received then.
2015-12-28resolved: only keep a single list of supported signature algorithmsLennart Poettering
This removes dnssec_algorithm_supported() and simply uses the algorithm_to_gcrypt() result as indication whether a DNSSEC algorithm is supported. The patch also renames "algorithm" to "md_algorithm", in a few cases, in order to avoid confusion between DNSSEC signature algorithms and gcrypt message digest algorithms.

2015-12-28shared: relax restrictions on valid domain name characters a bitLennart Poettering
Previously, we'd not allow control characters to be embedded in domain names, even when escaped. Since cloudflare uses \000 however to implement its synthethic minimally covering NSEC RRs, we should allow them, as long as they are properly escaped.
2015-12-28nspawn: userns and unified cgroup: chown cgroup.eventsAlban Crequy
When starting a container in a new user namespace, systemd-nspawn chowns the cgroup knob files so they are usable by the container. But the cgroup knob file "cgroup.events" was missing. This file exists when the unified hierarchy is used.
