Hello!We are very happy to release dnsdist 1.7.1 today, a maintenance release fixing a few bugs reported since 1.7.0:
- A use-after-free error could happen if a network error occurred in the middle of a XFR query, for a proxy-protocol-enabled backend, leading to a crash - The TLS Server Name Indication was not properly set on outgoing DNS over HTTPS or DNS over TLS connections to a backend - The health-check timeout was not properly set for outgoing DNS over HTTPS connections, leading to a very long timeout - The outgoing protocol was not always properly set in our in-memory ring buffers - Outgoing UDP timeouts were sometimes processed a bit too late when the health-check interval was set to more than one second
- Filtering qnames via eBPF was broken- The dynamic block mechanism was not properly switching to eBPF filtering, when available, if the block action was not explicitly set
- The latency histogram was broken in our prometheus metrics - Trying to create a 0-sized packet cache would lead to a crashIn addition to these fixes, our Docker images no longer have capability requirements. More information on that topic is available in our upgrade guide [1].
We also improved our compatibility with OpenSSL 3.0.0's API.As usual there were also other smaller enhancements and fixes, please see the dnsdist website [2] for the more complete changelog [3] 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 [4].
The release tarball [5] and its signature [6] are available on the downloads website, and packages for several distributions are available from our repository [7].
Finally, we would like to thank the PowerDNS community and all external contributors for their great work in this release!
