PowerDNS Recursor 4.1.3 Released

May 22, 2018

This release improves the stability and resiliency of the RPZ implementation, prevents metrics gathering from slowing down the processing of DNS queries and fixes an issue related to the cleaning of EDNS Client Subnet entries from the cache.

The full changelog looks like this:

Improvements

  • #6583: Add _raw versions for QName / ComboAddresses to the FFI API.
  • #6611, #6130: Update copyright years to 2018 (Matt Nordhoff).
  • #6474, #6596, #6478: Fix a warning on botan >= 2.5.0.

Bug Fixes

  • #6313: Count a lookup into an internal auth zone as a cache miss.
  • #6467: Don’t increase the DNSSEC validations counters when running with process-no-validate.
  • #6469: Respect the AXFR timeout while connecting to the RPZ server.
  • #6418, #6179: Increase MTasker stacksize to avoid crash in exception unwinding (Chris Hofstaedtler).

  • #6588, #6237: Delay the loading of RPZ zones until the parsing is done, fixing a race condition.
  • #6595, #6542, #6516, #6358, #6517: Reorder includes to avoid boost L conflict.
