SAMBA+ 4.23.12 released – internal DNS and scavenging fixes

SAMBA+ 4.23.12 has been released by SerNet and is now available for SUSE and Red Hat platforms, Debian GNU/Linux, Ubuntu, and AIX. It is the latest stable release of the Samba 4.23 series.

This release addresses several issues reported since Samba 4.23.11, including the internal DNS service failing to switch from UDP to TCP for packets larger than 4k, EDNS usage in the DNS client, DNS scavenging running even when fAging is FALSE, and a CTDB fix that stops an inactive node from running recovery and leaving databases inconsistent. Stream create-disposition handling after a prior handle was closed has also been corrected. All fixes are documented in the official release notes:

If you are upgrading from a SAMBA+ version older than 4.21 and use your own or third-party scripts that rely on Samba's Python modules, you must install the sernet-samba-python3 package after upgrading on Debian or Ubuntu systems. RHEL and SUSE-based systems are not affected.

As usual, the new packages are included in existing SAMBA+ subscriptions and can be obtained via the SAMBA+ shops:

Meet the SAMBA+ Team at SDC 2026

This September, SAMBA+ will be joining again the SNIA Developer Conference (SDC) in Santa Clara, California, as a sponsor. From 28–30 September 2026, the conference will once again bring together storage technology professionals, open-source developers, and infrastructure experts to discuss the latest innovations in enterprise storage and file services.

The conference program features four presentations by members of the SerNet Samba Team, covering technical innovations as well as the future direction of the Samba project.

Conference Highlights

Ralph Böhme, SAMBA+ Teamlead at SerNet, will present "Samba Foundation Moves to Europe", explaining why the project's legal home has moved to Berlin and what this means for digital sovereignty, open source, SMB technologies, and the broader Samba community.
Volker Lendecke will provide an outlook on upcoming developments in "Samba in 2026", sharing insights into the project's current status and future direction.
In "SMB3 POSIX Extensions, from plumbing to flowing", Ralph Böhme will demonstrate how the now fully implemented SMB3 POSIX Extensions can be deployed in real-world Linux and Samba environments, and discuss the future of the protocol specification.
Stefan Metzmacher will present "New Transports in Samba: QUIC and SMBDirect, with High-Speed I/O via io_uring", highlighting the latest progress on native QUIC and SMBDirect support in Linux and Samba, with a focus on performance and upstream integration.
