9 These are the release notes for nbdkit stable release 1.34. This
10 describes the major changes since 1.32.
11 nbdkit 1.34.0 was released on 14 April 2023.
13 Security
15 Various sanity checks were added to nbdkit-luks-filter(1) so it can
16 handle untrusted disk images.
17 TLS support was hardened against a Man-in-the-Middle attacker injecting
19 unknown NBD options before STARTTLS (Eric Blake).
20 Fix rare assertion failure (denial of service) which can be triggered
22 by clients hanging up early (Eric Blake).
23 All past security issues and information about how to report new ones
25 can be found in nbdkit-security(1).
26 Plugins
28 New nbdkit-blkio-plugin(1) allows you to easily consume and automate
29 the libblkio high performance storage library. This allows you to
30 (amongst other things) access local vhost-user and VFIO devices (thanks
31 Alberto Faria and Stefan Hajnoczi).
32 nbdkit-file-plugin(1) has new "fd" and "dirfd" parameters allowing a
34 file or directory to be passed from a parent process through a file
35 descriptor.
36 Several enhancements were made to nbdkit-curl-plugin(1), concentrating
38 on improved performance and functionality:
39 • Multi-conn is now enabled for read-only connections (thanks Eric
41 Blake).
42 • Instead of using one libcurl handle per NBD client, we now use a
44 common pool of handles, which improves performance.
45 • Fix the "tls13-ciphers" parameter (Michal Orzel).
47 • We now use the new CURLOPT_PROTOCOLS_STR(3) feature of libcurl (if
49 available) instead of hard-coding the list of protocols into the
50 plugin.
51 • Support was added for forcing "ssl-version", http-version
53 nbdkit-vddk-plugin(1) now supports VDDK 8 (thanks Ming Xie, Alice
55 Frosi).
56 nbdkit-torrent-plugin(1) was ported to macOS (Eric Blake).
58 Filters
60 nbdkit-blocksize-policy-filter(1) has a new
61 "blocksize-write-disconnect" to force a disconnection if a client
62 attempts a write larger than a certain threshold (Eric Blake).
63 nbdkit-retry-filter(1) can now retry plugin open (Eric Blake).
65 Language bindings
67 nbdkit-python-plugin(3) now rejects extra parameters to "export_name"
68 and "shutdown" functions (Eric Blake).
69 Tracebacks from Python plugins should now include the full method name
71 (Eric Blake).
72 nbdkit-sh-plugin(3) status codes have changed in this release, although
74 in a way that will normally be backwards compatible with older plugins.
75 Two new status codes are reserved for shutdown server and disconnect
76 client. Check the manual page for details. (Eric Blake)
77 Server
79 "nbdkit --dump-config" now reports "exit_with_parent=yes|no" so you can
80 tell if the optional exit with parent functionality is enabled on the
81 platform.
82 Debug messages from filters and plugins are now picked out in bold,
84 making them easier to read amongst other nbdkit debug messages.
85 API
87 New "nbdkit_disconnect" API which allows a plugin or filter to drop the
88 connection to the current client (Eric Blake).
89 Bug fixes
91 Fix a deadlock in nbdkit-exitwhen-filter(1) (Piotr Dobrowolski).
92 Fix the error message in nbdkit-ssh-plugin(1) when the known_hosts file
94 is not readable (thanks Jonathon Jongsma).
95 Documentation
97 The --help output of plugins is now consistent with the manual pages,
98 and extra tests were added to ensure it stays this way.
99 Tests
101 Multiple CI improvements, particularly for Alpine Linux and macOS (Eric
102 Blake).
103 Build
105 Most "./configure"-time features can now be both enabled and disabled
106 using --with-feature and --without-feature (Arsen Arsenović).
107 Multiple VPATH build problems fixed (Eric Blake).
109 Internals
111 Use Subject Alternative Name instead of commonName in test certificates
112 and suggest its use in documentation (thanks Daniel Berrangé).
113 Source files reformatted to use ≤ 80 columns (Laszlo Ersek).
