nbdkit-release-notes-1.34 - release notes for nbdkit 1.34

DESCRIPTION

These are the release notes for nbdkit stable release 1.34. This describes the major changes since 1.32.

nbdkit 1.34.0 was released on 14 April 2023.

Security

Various sanity checks were added to nbdkit-luks-filter(1) so it can handle untrusted disk images.

TLS support was hardened against a Man-in-the-Middle attacker injecting unknown NBD options before STARTTLS (Eric Blake).

Fix rare assertion failure (denial of service) which can be triggered by clients hanging up early (Eric Blake).

All past security issues and information about how to report new ones can be found in nbdkit-security(1).

Plugins

New nbdkit-blkio-plugin(1) allows you to easily consume and automate the libblkio high performance storage library. This allows you to (amongst other things) access local vhost-user and VFIO devices (thanks Alberto Faria and Stefan Hajnoczi).

nbdkit-file-plugin(1) has new fd and dirfd parameters allowing a file or directory to be passed from a parent process through a file descriptor.

Several enhancements were made to nbdkit-curl-plugin(1), concentrating on improved performance and functionality:

nbdkit-vddk-plugin(1) now supports VDDK 8 (thanks Ming Xie, Alice Frosi).

nbdkit-torrent-plugin(1) was ported to macOS (Eric Blake).

Filters

nbdkit-blocksize-policy-filter(1) has a new blocksize-write-disconnect to force a disconnection if a client attempts a write larger than a certain threshold (Eric Blake).

nbdkit-retry-filter(1) can now retry plugin open (Eric Blake).

Language bindings

nbdkit-python-plugin(3) now rejects extra parameters to export_name and shutdown functions (Eric Blake).

Tracebacks from Python plugins should now include the full method name (Eric Blake).

nbdkit-sh-plugin(3) status codes have changed in this release, although in a way that will normally be backwards compatible with older plugins. Two new status codes are reserved for shutdown server and disconnect client. Check the manual page for details. (Eric Blake)

Server

nbdkit --dump-config now reports exit_with_parent=yes|no so you can tell if the optional exit with parent functionality is enabled on the platform.

Debug messages from filters and plugins are now picked out in bold, making them easier to read amongst other nbdkit debug messages.

API

New nbdkit_disconnect API which allows a plugin or filter to drop the connection to the current client (Eric Blake).

Bug fixes

Fix a deadlock in nbdkit-exitwhen-filter(1) (Piotr Dobrowolski).

Fix the error message in nbdkit-ssh-plugin(1) when the known_hosts file is not readable (thanks Jonathon Jongsma).

Documentation

The --help output of plugins is now consistent with the manual pages, and extra tests were added to ensure it stays this way.

Tests

Multiple CI improvements, particularly for Alpine Linux and macOS (Eric Blake).

Build

Most ./configure-time features can now be both enabled and disabled using --with-feature and --without-feature (Arsen Arsenović).

Multiple VPATH build problems fixed (Eric Blake).

Internals

Use Subject Alternative Name instead of commonName in test certificates and suggest its use in documentation (thanks Daniel Berrangé).

Source files reformatted to use ≤ 80 columns (Laszlo Ersek).
