2015-11-25dns-domain: change dns_srv_type_is_valid() return value to boolLennart Poettering
For similar reasons as dns_name_is_root() got changed in the previous commit.
2015-11-25dns-domain: simplify dns_name_is_root() and dns_name_is_single_label()Lennart Poettering
Let's change the return value to bool. If we encounter an error while parsing, return "false" instead of the actual parsing error, after all the specified hostname does not qualify for what the function is supposed to test. Dealing with the additional error codes was always cumbersome, and easily misused, like for example in the DHCP code. Let's also rename the functions from dns_name_root() to dns_name_is_root(), to indicate that this function checks something and returns a bool. Similar for dns_name_is_signal_label().
2015-11-24resolved: implement client-side DNAME resolutionLennart Poettering
Most servers apparently always implicitly convert DNAME to CNAME, but some servers don't, hence implement this properly, as this is required by edns0.
2015-11-23dns-domain: add calls to join/split SRV/DNS-SD service domainsLennart Poettering
This adds dns_service_join() and dns_service_split() which may be used to concatenate a DNS-SD service name, am SRV service type string, and a domain name into a full resolvable DNS domain name string. If the service name is specified as NULL, only the type and domain are appended, to implement classic, non-DNS-SD SRV lookups. The reverse is dns_service_split() which takes the full name, and split it into the three components again.
2015-11-23dns-domain: add code for verifying validity of DNS-SD service names and typesLennart Poettering
2015-11-17dns-domain: add dns_name_to_wire_format()Beniamino Galvani
The function converts a domain name string to the wire format described in RFC 1035 Section 3.1.
2015-10-27util-lib: split out allocation calls into alloc-util.[ch]Lennart Poettering
2015-10-27util-lib: split out hex/dec/oct encoding/decoding into its own fileLennart Poettering
2015-10-27util-lib: split string parsing related calls from util.[ch] into parse-util.[ch]Lennart Poettering
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-10-05hashmap: hash_funcs - make inputs unambiguousTom Gundersen
Make sure all variable-length inputs are properly terminated or that their length is encoded in some way. This avoids ambiguity of adjacent inputs. E.g., in case of a hash function taking two strings, compressing "ab" followed by "c" is now distinct from "a" followed by "bc".
2015-10-05hashmap: refactor hash_funcTom Gundersen
All our hash functions are based on siphash24(), factor out siphash_init() and siphash24_finalize() and pass the siphash state to the hash functions rather than the hash key. This simplifies the hash functions, and in particular makes composition simpler as calling siphash24_compress() repeatedly on separate chunks of input has the same effect as first concatenating the input and then calling siphash23_compress() on the result.
2015-08-21dns-domain: add call for concatenating two domain namesLennart Poettering
This is specifically useful for appending the mDNS ".local" suffix to a single-label hostname in the most correct way. (used in later commit)
2015-07-28shared: dns-name - add dns_name_between()Tom Gundersen
Given three DNS names this function indicates if the second argument lies strictly between the first and the third according to the canonical DNS name order. Note that the order is circular, so the last name is considered to be before the first.
2015-07-28shared: dns-name - use the canonical dns name orderingTom Gundersen
The canonical DNS name ordering considers the rightmost label the most significant, we were considering it the least significant. This is important when implementing NSEC, which relies on the correct order.
2015-07-28shared: dns-name - introduce dns_label_unescape_suffix()Tom Gundersen
Intended to be called repeatedly, and returns then successive unescaped labels from the most to the least significant (left to right). This is slightly inefficient as it scans the string three times (two would be sufficient): once to find the end of the string, once to find the beginning of each label and lastly once to do the actual unescaping. The latter two could be done in one go, but that seemed unnecessarily convoluted.
