The releases address premature termination of DNS-over-TLS and DNS-over-HTTPS connections when using the OpenSSL provider; PowerDNS says this is not a security issue and advises affected users to upgrade. They also fix a possible use-after-free crash when adding a rule. Version 2.1.3 includes AF_XDP/XSK fixes and tighter access controls for dashboard metrics when the dashboard is configured without a password. ### Source excerpt Today we released DNSdist 2.1.3 and 2.0.11, fixing several issues. The notable one fixes an issue where incoming DNS over TLS and DNS over HTTPS connections could have been wrongly terminated early, when the OpenSSL provider is in use. We advise all users providing DNS over TLS or DNS over HTTPS to upgrade, but to be clear this is NOT a security issue. ## Enabling more default features in NSD 4.13.0 DevFeed: [Enabling more default features in NSD 4.13.0]() Original publisher: [Read original article]() Author: Team NLnet Labs Published: 2025-09-03T10:15:12Z Content type: release Language: en Sources: [NLnet Labs]() Topics: [version]() Tags: [configure](), [experimental](), [features](), [nsd](), [sockets](), [version](), [xdp]() ### AI overview NSD 4.13.0 enables several features by default, including BIND 8 statistics, zone statistics, rate limiting, and dnstap. The release also adds experimental support for AF_XDP sockets, configurable through a configure option. ### Source excerpt By Jannik Peters NSD 4.13.0 now comes with the features --enable-bind8-stats, --enable-zone-stats, --enable-ratelimit, --enable-dnstap enabled by default, reducing confusion when using the same version of NSD packaged by different distributions with different configure options. Additionally, NSD 4.13.0 contains experimental support ## Experimental support for AF\_XDP sockets in NSD DevFeed: [Experimental support for AF\_XDP sockets in NSD]() Original publisher: [Read original article]() Author: Team NLnet Labs Published: 2025-05-26T13:30:00Z Content type: article Language: en Sources: [NLnet Labs]() Topics: [Network](), [eBPF](), [Linux Kernel](), [Linux](), [Hardware](), [implementation](), [debugging]() Tags: [debugging](), [dns](), [drivers](), [ebpf](), [experimental](), [implementation](), [linux](), [linux-kernel](), [load-balancing](), [network](), [network-packets](), [network-stack](), [nsd](), [sockets](), [version](), [xdp]() ### AI overview This article describes experimental AF_XDP socket support in NSD for processing DNS queries at high packet rates. It explains how XDP and eBPF process packets early in the Linux networking path, discusses driver and hardware compatibility issues, and reports a 1.7x improvement over UDP through the network stack with zero-copy disabled. ### Source excerpt By Jannik Peters We have been developing support for AF_XDP sockets in NSD. They allow handling a higher rate of network packets than through the Linux network stack on supported hardware[1]--For a list of supported drivers (and by extension hardware) and their minimum Linux kernel version
