2016-01-11resolved: rework trust anchor revoke checkingLennart Poettering
Instead of first iterating through all DNSKEYs in the DnsAnswer in dns_transaction_check_revoked_trust_anchors(), and then doing that a second time in dns_trust_anchor_check_revoked(), do so only once in the former, and pass the dnskey we found directly to the latter.
2016-01-11resolved: look for revoked trust anchors before validating a messageLennart Poettering
There's not reason to wait for checking for revoked trust anchors until after validation, after all revoked DNSKEYs only need to be self-signed, but not have a full trust chain. This way, we can be sure that all trust anchor lookups we do during validation already honour that some keys might have been revoked.

2016-01-11resolved: remove one level of indentation in dns_transaction_validate_dnssec()Lennart Poettering
Invert an "if" check, so that we can use "continue" rather than another code block indentation.

This increases compatibility with crappy Belkin routers.
2016-01-11resolved: rename suffix_rr → zone_rrLennart Poettering
The domain name for this NSEC3 RR was originally stored in a variable called "suffix", which was then renamed to "zone" in d1511b3338f431de3c95a50a9c1aca297e0c0734. Hence also rename the RR variable accordingly.

macro.h: improve IN_SET helper macro
2016-01-11macro.h: provide a switch-case statement generator for IN_SETDaniel Mack
Rather than walking a list of valid values one-by-one, generate a switch-case statement for the IN_SET() macro. This allows the compiler to further optimize its code output, possibly by generating jump tables. This effectively decreases the binary size slightly. The implementation is based on macro overloading depending on the number of arguments. h/t to the following post: https://stackoverflow.com/questions/11761703/overloading-macro-on-number-of-arguments
2016-01-11smack: Handling networkCasey Schaufler
- Set Smack ambient to match run label - Set Smack netlabel host rules Set Smack ambient to match run label ------------------------------------ Set the Smack networking ambient label to match the run label of systemd. System services may expect to communicate with external services over IP. Setting the ambient label assigns that label to IP packets that do not include CIPSO headers. This allows systemd and the services it spawns access to unlabeled IP packets, and hence external services. A system may choose to restrict network access to particular services later in the startup process. This is easily done by resetting the ambient label elsewhere. Set Smack netlabel host rules ----------------------------- If SMACK_RUN_LABEL is defined set all other hosts to be single label hosts at the specified label. Set the loopback address to be a CIPSO host. If any netlabel host rules are defined in /etc/smack/netlabel.d install them into the smackfs netlabel interface.

2016-01-06resolved: populate negative trust anchor by defaultLennart Poettering

2016-01-05resolved: try to detect fritz.box-style private DNS zones, and downgrade to ↵Lennart Poettering
non-DNSSEC mode for them This adds logic to detect cases like the Fritz!Box routers which serve a private DNS domain "fritz.box" under the TLD "box" that does not exist in the root servers. If this is detected DNSSEC validation is turned off for this private domain, thus improving compatibility with such private DNS zones. This should be fairly secure as we first rely on the proof that .box does not exist before this logic is applied. Nevertheless the logic is only enabled for DNSSEC=allow-downgrade mode. This logic does not work for routers that set up a full DNS zone directly under a non-existing TLD, as in that case we cannot prove that the domain is truly non-existing according to the root servers.

2016-01-05resolved,networkd: unify ResolveSupport enumLennart Poettering
networkd previously knew an enum "ResolveSupport" for configuring per-interface LLMNR support, resolved had a similar enum just called "Support", with the same value and similar pasers. Unify this, call the enum ResolveSupport, and port both daemons to it.
2016-01-05basic: add string table macros for "extended boolean" enumsLennart Poettering
In a couple of cases we maintain configuration settings that know an on and off state, like a boolean, plus some additional states. We generally parse them as booleans first, and if that fails check for specific additional values. This adds a generalized set of macros for parsing such settings, and ports one use in resolved and another in networkd over to it.

2016-01-05resolved: also skip built-in trust anchor addition of there's a DNSKEY RR ↵Lennart Poettering
for the root domain defined We already skip this when the trust anchor files define a DS RR for the root domain, now also skip it if there's a DNSKEY RR.

2016-01-05mount-setup.c: fix handling of symlink Smack labelling in cgroup setupPatrick Ohly
The code introduced in f8c1a81c51 (= systemd 227) failed for me with: Failed to copy smack label from net_cls to /sys/fs/cgroup/net_cls: No such file or directory There is no need for a symlink in this case because source and target are identical. The symlink() call is allowed to fail when the target already exists. When that happens, copying the Smack label must be skipped. But the code also failed when there is a symlink, like "cpu -> cpu,cpuacct", because mac_smack_copy() got called with src="cpu,cpuacct" which fails to find the entry because the current directory is not inside /sys/fs/cgroup. The absolute path to the existing entry must be used instead.
2016-01-05resolved: when caching negative responses, honour NSEC/NSEC3 TTLsLennart Poettering
When storing negative responses, clamp the SOA minimum TTL (as suggested by RFC2308) to the TTL of the NSEC/NSEC3 RRs we used to prove non-existance, if it there is any. This is necessary since otherwise an attacker might put together a faked negative response for one of our question including a high-ttl SOA RR for any parent zone, and we'd use trust the TTL.
