Dear all,

We have a first release candidate for the upcoming 1.2.2 bugfix release of getdns.

Recently Stubby has seen increased interest.
Already after the release of the Windows installer, but even more so after the introduction of Quad9 and the description of how to use DNS-over-TLS with Stubby by Alex Band and Stéphane Borzmeyer.

The increased install base has generated excellent feedback and has also revealed some bugs.
This release has those bugs fixed, and also contains a few more configuration options to be able to adapt to more diverse situations.

The bugs fixed with this release are:

  • A segfault with the native DNSSEC validation code when DS and DNSKEY queries timed out,
  • A non RFC compliant edns_client_subnet_private option that caused some upstream EDNS Client Subnet implementations (i.e. Unbound's) to return FORMERR, and
  • Doing the meta queries for Zero configuration DNSSEC with the resolvers from /etc/resolv.conf, which cause Stubby to query itself for this, effectively breaking the possibility to fetch the root trust-anchors and bootstrap DNSSEC.

Besides these fixes, this release allows to configure a getdns_context to be initialized with resolv.conf and hosts at alternative locations, with the getdns_context_set_resolvconf() and getdns_context_set_hosts() functions.
Also a specific location for the CA store, for authenticating DNS-over-TLS upstreams, can be specified with the getdns_context_set_CApath() and getdns_context_set_CAfile() functions.

The getdns_context_get_api_information() function exposes more getdns_context settings, amongst which:

  • The default settings for extensions,
  • The paths for files that were used to initialize a getdns_context (resolv.conf, hosts and trust anchors), and
  • More information about the version, configuration and capabilities of the OpenSSL library in use.

This release candidate includes a candidate for a 0.2.0 release of Stubby.
The most prominent bugfix therein is to not do DNSSEC validation for queries with the CD bit set, when DNSSEC validation was not configured in the first place.
This bug caused decreased performance for configurations with an unbound forwarding to Stubby.

The 0.2.0 release (candidate) of Stubby also includes some additional auxiliary functionality which is used by the macOS prototype GUI that was just released: https://dnsprivacy.org/wiki/display/DP/Stubby+GUI+for+macOS

Please review this release candidate carefully, if all is well, the actual release will follow Thursday the 21th of December.

ChangeLog

* 2017-12-??: Version 1.2.2
  * Bugfix #356: Do Zero configuration DNSSEC meta queries over on the
    context configured upstreams.
  * Report default extension settings with
    getdns_context_get_api_information()
  * Specify locations at which CA certificates for verification purposes
    are located: getdns_context_set_CApath() getdns_context_set_CAfile()
  * getdns_context_set_resolvconf() function to initialize a context 
    upstreams and suffices with a resolv.conf file.
    getdns_context_get_resolvconf() to get the file used to initialize
    the context's upstreams and suffixes.
    getdns_context_set_hosts() function to initialize a context's
    LOCALNAMES namespace.
    getdns_context_get_hosts() function to get the file used to initialize
    the context's LOCALNAMES namespace.
  * get which version of OpenSSL was used at build time and at run time
    when available with getdns_context_get_api_information()
  * GETDNS_RETURN_IO_ERROR return error code
  * Bugfix #359: edns_client_subnet_private should set family
    Thanks Daniel Areiza
  * Bugfix getdnsapi/stubby#34: Segfault issue with native DNSSEC
    validation.  Thanks Bruno Pagani

Stubby ChangeLog

* 2017-12-?: Version 0.2.0
  * Add files to support a separate macOS GUI application to manage stubby
  * Bugfix #48: Do not do native DNSSEC validation when cd bit was
    received (for example from an unbound forwarder), but DNSSEC
    validation was not enabled in the first place.
  * Bugfix getdnsapi/getdns#358: Parse config files given with the
    -C option that have an .yaml extension as YAML not JSON.
    Thanks Ollivier Robert
