2020-01-27 r/464 feat(lisp/dns): Support CNAME & NS record RDATAsVincent Ambo2-378/+64
2020-01-27 r/463 refactor(lisp/dns): Refactor structure of lookup-generic callsVincent Ambo1-9/+12
2020-01-26 r/460 chore(lisp/dns): Remove unused dependenciesVincent Ambo1-2/+0
2020-01-26 feat(lisp/dns): Export struct fieldsVincent Ambo1-3/+3
2020-01-26 feat(lisp/dns): Introduce enum for DNS types & decode RDATAVincent Ambo1-2/+21
Adds some of the most common DNS types in the enum (others TBD), and starts decoding RDATA for TXT and A.
2020-01-26 chore(lisp/dns): Add 'message.lisp' to build instructionsVincent Ambo1-0/+1
2020-01-26 feat(lisp/dns): Use new DNS deserialiser in dns:lookup-genericVincent Ambo1-152/+52
This enables arbitrary DNS lookups (with the caveat that RRDATAs are currently not deserialised into a record-type-specific format). An error condition has been defined for error-responses from the HTTP server which provides interactive restarts for attempting a new call with different parameters.
2020-01-26 feat(lisp/dns): Implement qname compression parsingVincent Ambo1-270/+29
Implements support for the compresion scheme used in binary DNS messages. This makes it possible to decode messages entirely, but not yet actually resolve the labels to their "real" values. All qnames are stored with file-offsets pointing at the position at which their reading started, which enables the implementation of a function to resolve pointers internally.
2020-01-26 refactor(lisp/dns): Introduce structured QNAME representationVincent Ambo1-31/+51
Adds a struct that represents QNAMEs, tracks the stream offset at which the QNAME parsing began and makes it possible to resolve pointers inside of the QNAME. Note that resolving pointers needs to happen *after* the call to lisp-binary currently. It might be possible to implement this inside of lisp-binary in the future by switching on the top two bits of the qname field, but since this is happening *inside* of a reader function I'm not currently sure how to implement it.
2020-01-26 feat(lisp/dns): Check in initial DNS message implementationVincent Ambo1-0/+931
This uses lisp-binary to define serialisation types for the DNS messages defined by RFC 1035. Currently the compression scheme used for QNAMEs is not supported, hence deserialisation of even simple records fails after the header and question sections are read.
2020-01-26 refactor(lisp/dns): Split package into multiple filesVincent Ambo4-31/+182
Adds a package definition file and moves the current client into client.lisp Note that the client is not working at all at this commit as this is a work-in-progress snapshot.
2020-01-22 r/448 feat(lisp/dns): Check in very early DNS-over-HTTPS clientVincent Ambo2-0/+44
This includes very barebones support for querying TXT and MX records right now. The returned structure is not turned into a more convenient format and error handling is, well, NIL.
