✨ NAME ✨

nbdkit-release-notes-1.42 β€” release notes for nbdkit 1.42 🫢


🌸 DESCRIPTION 🌸

These are the release notes for nbdkit stable release 1.42. It's giving "what's new since 1.40" energy, and it covers the major changes, no cap.

nbdkit 1.42.0 was released on 11 February 2025. mark your calendars, that's a whole moment πŸ“…βœ¨


πŸ”’ Security πŸ”’

nbdkit-ip-filter(1) has been fixed to close an information leak πŸ˜­πŸ™ˆ. In an unusual configuration of the filter, it could leak the list of exports to clients that are supposed to be blocked. like, the whole point was that they're blocked?? anyway, fixed, slay.

πŸ’€ all past security issues and info about how to report new ones live in nbdkit-security(1). go read it, iykyk.

🧩 Plugins 🧩

  • nbdkit-ondemand-plugin(1) now allows more characters to appear in filenames. Colons are now allowed, so filenames containing MAC addresses can be used, which is useful when using NBD in pre-boot environments. Also, the share=true option was added to allow sharing. (Thanks Markus Hartung πŸ’œ)
  • nbdkit-vddk-plugin(1) now prints the default list of transports in --dump-plugin output. Also this plugin now handles partial chunks correctly when reading extents for disks with a non-aligned size (thanks Ming Xie πŸ’œ).

πŸŽ€ Filters πŸŽ€

  • New nbdkit-time-limit-filter(1) can be used to specify the maximum time limit for a connection. (See also the new --timeout option below πŸ‘€)
  • New nbdkit-lzip-filter(1) implements random access to lzip-compressed files (Jan Felix Langenbach).

πŸ¦‹ Language bindings πŸ¦‹

  • Multiple updates to nbdkit-rust-plugin(3) to keep up to date with latest changes in the Rust language (Alan Somers).
  • Fix crash that happened in nbdkit-ocaml-plugin(3) plugins with OCaml β‰₯ 5 (thanks Guillaume Munch-Maccagnoni, Gabriel Scherer). Also update the ocamldoc documentation. Fix more OCaml 5 deprecation warnings. the way that crash was just living in there rent free 😭
  • Add support for Tcl 9.0 to nbdkit-tcl-plugin(3). periodt.

πŸ‘‘ Server πŸ‘‘

  • nbdkit will now try to send the last plugin error message over the NBD protocol to the client, to provide additional information. This requires an NBD client which supports this, such as qemu β‰₯ 2.12 or libnbd β‰₯ 1.22. iconic behaviour honestly.
  • New nbdkit --timeout flag can be used as a security measure to ensure that clients don't consume resources by opening lots of connections and then not negotiating (or negotiating slowly) the full NBD session. main character anti-DoS energy πŸ”₯
  • New nbdkit --keepalive option which enables TCP-level keepalives. This is useful for detecting dead clients. vibe check on the socket fr fr πŸ’…
  • nbdkit --dump-config output now includes timeout_option=yes|no and vsock_option=yes|no, reflecting whether the --timeout and --vsock options are available.

πŸ› Bug fixes πŸ›

Detect and warn about certain conditions which can cause the closed-source VDDK library to crash the server (Matthew Arnold, Nijin Ashok, Eric Blake). we love a warning instead of a crash, that's the dream 🫢

Plugins from nbdkit 1.38 have been added to the tests/old-plugins directory. vintage era, but make it regression-tested ✨
