PowerDNS DNSdist 1.9.2 released

Apr 5, 2024

We released PowerDNS DNSdist 1.9.2 today. This release fixes several issues:

  • HTTP/1.1 was wrongly selected over HTTP/2 when a DNS over HTTPS client advertised both HTTP versions in ALPN and listed HTTP/1.1 first, and the nghttp2 provider was used
  • The first connection to the DNSdist console done over IPv6 was rejected
  • A failure of the first lazy health-check was not properly handled
  • A crash might have occurred if an incoming DNS over HTTPS connection timed out right before the corresponding outgoing query to a backend did, and the nghttp2 provider was used
  • DNS over HTTPS connections and queries counters were not working properly with the nghttp2 provider
  • Incoming TCP connections from a client were not always closed right away after an error
  • Outgoing TCP connections to a backend were not always closed right away after a timeout
  • The Docker image was printing the DNSdist configuration to the terminal by default, including secrets, which might not have been expected
  • It was not possible to return a "no server available" result from a custom Lua FFI load-balancing policy
  • Several compilation warnings have been fixed
Please see the DNSdist website for the more complete changelog and the current documentation.

Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.

The release tarball and its signature are available on the downloads website, and packages for several distributions are available from our repository.
