'nbdkit' is a toolkit for creating NBD servers. The key features are: * Multithreaded NBD server written in C with good performance. * Liberal license (BSD) allows nbdkit to be linked to proprietary libraries or included in proprietary code. * Well-documented, simple plugin API with a stable ABI guarantee. Let's you export "unconventional" block devices easily. * You can write plugins in C, Perl, Python or OCaml. For documentation, see the docs/ directory. For plugins and examples, see the plugins/ directory. License ------- This software is copyright (C) Red Hat Inc. and licensed under a BSD license. See LICENSE for details. Building from source -------------------- By default nbdkit needs nothing except Linux and reasonably recent gcc. To build the man pages, you will need to install: - pod2man (included with perl) There are some *optional* libraries you may want to install for the plugins. For the gzip plugin: - zlib For the xz plugin: - liblzma For the curl (HTTP/FTP) plugin: - libcurl For the libvirt plugin: - libvirt For the libguestfs plugin, and to run the test suite: - libguestfs - guestfish (from libguestfs) For the VDDK plugin: - VDDK (see plugins/vddk/README.VDDK) For the Perl plugin: - perl development libraries - perl module ExtUtils::Embed For the Python plugin: - python development libraries For the OCaml plugin: - OCaml >= 4.02.2 which has support for shared libraries, see: http://caml.inria.fr/mantis/view.php?id=6693 After installing any dependencies: To build from tarball: To build from git: ---------------------- ------------------ autoreconf -i ./configure ./configure make make make check make check Optionally run this as root to install everything: make install Tests ----- You will need to install libguestfs to run the test suite. The test suite ('make check') is fairly comprehensive. It runs the newly built nbdkit + plugin as a captive process, and tests it using libguestfs. If there is a failure, look at the corresponding tests/*.log file for debug information. Packager information -------------------- Tarballs are available from: http://libguestfs.org/download/nbdkit Developer information --------------------- For development ideas, see the TODO file. The upstream git repository is: https://github.com/libguestfs/nbdkit Please send patches to the libguestfs mailing list: https://www.redhat.com/mailman/listinfo/libguestfs For further information, see: http://libguestfs.org/ nbdkit-1.1.11/src/0000775000175000017500000000000012615132775010651 500000000000000nbdkit-1.1.11/src/main.c0000664000175000017500000003756612615131623011671 00000000000000/* nbdkit * Copyright (C) 2013-2014 Red Hat Inc. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions are * met: * * * Redistributions of source code must retain the above copyright * notice, this list of conditions and the following disclaimer. * * * Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. * * * Neither the name of Red Hat nor the names of its contributors may be * used to endorse or promote products derived from this software without * specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY RED HAT AND CONTRIBUTORS ''AS IS'' AND * ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, * THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A * PARTICULAR PURPOSE ARE DISCLAIMED.

See: http://article.gmane.org/gmane.linux.drivers.nbd.general/3154 * Can we do language bindings using #!'s? You would enter: nbdkit foo [args] where nbdkit-foo-plugin is a Perl script starting: #!perl which causes nbdkit to load the perl plugin wrapper. * syslog? journal? * Glance and/or cinder plugins. * Performance - measure and improve it. * Implement the new protocol and export names. With export names it should be possible to have multiple plugins on the command line (each responding to a different export of course): nbdkit --export /foo plugin.so --export /bar another-plugin.so Note it should also be possible to either elect one plugin as the default that accepts all exportnames, or to divide the export name "space" up using regexps or wildcards. * Implement true parallel request handling. Currently NBDKIT_THREAD_MODEL_SERIALIZE_REQUESTS and NBDKIT_THREAD_MODEL_PARALLEL are the same, because we handle requests within each connection synchronously one at a time. We could (and should) be able to handle them in parallel by having another thread pool for requests. nbdkit-1.1.11/config.guess0000755000175000017500000012743212156101037012314 00000000000000#! /bin/sh # Attempt to guess a canonical system name. # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, # 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, # 2011, 2012 Free Software Foundation, Inc. timestamp='2012-06-10' # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It serves the named C over NBD. =head1 PARAMETERS =over 4 =item B Serve the file named C. A device path can also be used here. This parameter is required. =item B =item BNNEms> Delay reads for C seconds or C milliseconds. This is used to simulate a slow or remote server, or to test certain kinds of race conditions in Linux. The default is no delay. =item B =item BNNEms> Delay writes for C seconds or C milliseconds. This is used to simulate a slow or remote server, or to test certain kinds of race conditions in Linux. The default is no delay. =back =head1 SEE ALSO L, L. =head1 AUTHORS Richard W.M.

It serves, readonly, from memory, a static blob of data which looks a little bit like a 100 MB disk image that contains a single empty partition. Mainly this is useful for testing nbdkit and as an example for writing nbdkit plugins (L). =head1 SEE ALSO L in the nbdkit source tree, L, L =head1 AUTHORS Richard W.M.

Broadly speaking, Python nbdkit plugins work like C ones, so you should read L first. =head2 USING A PYTHON NBDKIT PLUGIN Assuming you have a Python script which is an nbdkit plugin, you run it like this: nbdkit python script=/path/to/plugin.py You may have to add further C arguments to the command line. Read the Python script to see if it requires any. C I come first on the command line. =head1 WRITING A PYTHON NBDKIT PLUGIN There is an example Python nbdkit plugin called C which ships with the nbdkit source. To write a Python nbdkit plugin, you create a Python file which contains at least the following required functions (in the top level C<__main__> module): def open(readonly): # see below def get_size(h): # see below def pread(h, count, offset): # see below Note that the subroutines must have those literal names (like C), because the C part looks up and calls those functions directly. You may want to include documentation and globals (eg. for storing global state). Any other top level statements are run when the script is loaded, just like ordinary Python. The file does not need to include a C<#!> (hash-bang) at the top, and does not need to be executable. In fact it's a good idea not to do that, because running the plugin directly as a Python script won't work. =head2 EXCEPTIONS Python callbacks should throw exceptions to indicate errors. =head2 PYTHON CALLBACKS This just documents the arguments to the callbacks in Python, and any way that they differ from the C callbacks. In all other respects they work the same way as the C callbacks, so you should go and read nbdkit-plugin(3). =over 4 =item C (Optional) def config(key, value): # no return value =item C (Optional) There are no arguments or return value. =item C (Required) def open(readonly): # return handle You can return any non-NULL Python value as the handle. It is passed back in subsequent calls. =item C (Optional) def close(h): # no return value After C returns, the reference count of the handle is decremented in the C part, which usually means that the handle and its contents will be garbage collected. =item C (Required) def get_size(h): # return the size of the disk =item C (Optional) def can_write(h): # return a boolean =item C (Optional) def can_flush(h): # return a boolean =item C (Optional) def is_rotational(h): # return a boolean =item C (Optional) def can_trim(h): # return a boolean =item C (Required) def pread(h, count, offset): # construct a bytearray of length count bytes and return it The body of your C function should construct a buffer of length (at least) C bytes. You should read C bytes from the disk starting at C. NBD only supports whole reads, so your function should try to read the whole region (perhaps requiring a loop). If the read fails or is partial, your function should throw an exception. =item C (Optional) def pwrite(h, buf, offset): length = len (buf) # no return value The body of your C function should write the C string to the disk. You should write C bytes to the disk starting at C. NBD only supports whole writes, so your function should try to write the whole region (perhaps requiring a loop). If the write fails or is partial, your function should throw an exception. =item C (Optional) def flush(h): # no return value The body of your C function should do a L or L or equivalent on the backing store. =item C (Optional) def trim(h, count, offset): # no return value The body of your C function should "punch a hole" in the backing store. =back =head2 MISSING CALLBACKS =over 4 =item Missing: C and C These are not needed because you can just use ordinary Python constructs. =item Missing: C, C, C, C, C These are not yet supported. =back =head2 THREADS The thread model for Python callbacks currently cannot be set from Python.

If the NBD client opens the NBD port, and writes from the start to the end of the disk without seeking backwards, then this plugin will turn the resulting disk image into a stream of data which is written to the named C parameter. Typical usage is with qemu tools. For example: qemu-img convert input -O raw output does I work if C is a pipe. However this does: nbdkit -U /tmp/nbd.sock streaming pipe=output --run ' qemu-img convert -n input -O raw $nbd ' =head1 PARAMETERS =over 4 =item B Write to the named pipe or socket. If the pipe or socket does not exist, then it is created (as a named FIFO), otherwise the existing pipe or socket is opened and used. This parameter is required. =item B Specify the virtual size of the stream. This parameter is optional. If not specified, then the virtual disk appears to the client to be very large (effectively infinite). Whether you need to specify this parameter depends on the client. Some clients don't check the size and just write/stream, others do checks or calculations based on the apparent size. =back =head1 SEE ALSO L, L. =head1 AUTHORS Richard W.M.

It uses a library called libcurl (also known as cURL) to read data from URLs. The exact list of protocols that libcurl can handle depends on how it was compiled, but most versions will handle HTTP, HTTPS, FTP, FTPS and SFTP (see: S>). For more information about libcurl, see L. B This plugin supports writes. However: =over 4 =item * For HTTP, you may not want nbdkit to issue PUT requests to the remote server (which probably doesn't understand them). =item * SFTP helpfully truncates the target file when you open it for writing. Not useful! =back B flag>. =head2 EXAMPLES Basic usage is: nbdkit -r curl url=http://example.com/disk.img which serves the remote disk image as a NBD on TCP port 10809 (to control ports and protocols used to serve NBD see L). You can also access SSH servers. This uses the SFTP protocol which is built into most SSH servers: nbdkit -r curl url=sftp://example.com/~/disk.img You may need to specify a username and/or a password. In this example the password is read from stdin: nbdkit -r curl url=sftp://example.com/~/disk.img username=fred password=- =head1 PARAMETERS =over 4 =item B Set the password to use when connecting to the remote server. Note that passing this on the command line is not secure on shared machines. =item B Ask for the password (interactively) when nbdkit starts up. =item B Don't verify the SSL certificate of the remote host. =item B Set the timeout for requests. =item B Use the default libcurl timeout for requests. =item B The URL of the remote disk image.

It is implemented using the libvirt C API. It can also be used over remote libvirt connections. =head1 PARAMETERS =over 4 =item B This optional parameter specifies the libvirt connection URI. =item B This required parameter specifies the libvirt domain name (guest name). =item B This required parameter specifies the guest's disk that we want to read. You can either give the path to the backing device (C) or the target name (eg. C). In either case use C to list possible disks. Look for Ssource dev=...E>> or Ssource file=...E>> or Starget dev=...E>> in the XML. =back =head1 SEE ALSO L, L, L. =head1 AUTHORS Richard W.M.

It serves the named C over NBD, uncompressing it on the fly. The plugin only supports read-only connections. B that gzip files are not very good for random access in large files because seeking to a position in the gzip file involves uncompressing lots of data. A more practical method to compress large disk images is to use the L format and L. =head1 SEE ALSO L, L, L. =head1 AUTHORS Richard W.M.

On each connection, it generates a temporary writable block device of size C. The disk is thrown away when the client disconnects. The C parameter can use a number of common formats to specify the size, eg. C<100M>, C<2G>. If the parameter is omitted, it defaults to 100M. Mainly this is useful for testing nbdkit and as an example for writing nbdkit plugins (L). =head1 SEE ALSO L in the nbdkit source tree, L, L =head1 AUTHORS Richard W.M.

Broadly speaking, Perl nbdkit plugins work like C ones, so you should read L first. =head2 USING A PERL NBDKIT PLUGIN Assuming you have a Perl script which is an nbdkit plugin, you run it like this: nbdkit perl script=/path/to/plugin.pl You may have to add further C arguments to the command line. Read the Perl script to see if it requires any. C I come first on the command line. =head1 WRITING A PERL NBDKIT PLUGIN There is an example Perl nbdkit plugin called C which ships with the nbdkit source. To write a Perl nbdkit plugin, you create a Perl file which contains at least the following required subroutines: sub open { # see below } sub get_size { # see below } sub pread { # see below } Note that the subroutines must have those literal names (like C), because the C part looks up and calls those functions directly. You may want to include documentation and globals (eg. for storing global state). Also any top-level statements, C statements, C statements and so on are run when nbdkit starts up and shuts down, just like ordinary Perl. The file does I need to include a C<#!> (hash-bang) at the top, and does I need to be executable. In fact it's a good idea I to do that, because running the plugin directly as a Perl script won't work. =head2 EXCEPTIONS Instead of returning error codes as in C, Perl callbacks should indicate problems by throwing Perl exceptions (ie. C, C etc). The Perl error message is captured and printed by nbdkit. =head2 32 vs 64 BIT It is likely that Perl plugins won't work well, or maybe won't work at all, on 32 bit platforms. This is simply because Perl doesn't have an easy way to use 64 bit integers on 32 bit platforms, and 64 bit integers (eg. file offsets, disk sizes) are required for many nbdkit operations. =head2 PERL CALLBACKS This just documents the arguments to the callbacks in Perl, and any way that they differ from the C callbacks. In all other respects they work the same way as the C callbacks, so you should go and read L. =over 4 =item C (Optional) sub config { my $key = shift; my $value = shift; # No return value. } =item C (Optional) There are no arguments or return value. =item C (Required) sub open { my $readonly = shift; my $handle = {}; return $handle; } The C flag is a boolean. You can return any Perl value as the handle. It is passed back to subsequent calls. It's usually convenient to use a hashref, since that lets you store arbitrary fields. =item C (Optional) sub close { my $handle = shift; # No return value } After C returns, the reference count of the handle is decremented in the C part, which usually means that the handle and its contents will be garbage collected. =item C (Required) sub get_size { my $handle = shift; my $i64 = .. the size of the disk ..; return $i64; } This returns the size of the disk. You can return any Perl object that evaluates to an integer. =item C (Optional) sub can_write { my $handle = shift; my $bool = ...; return $bool; } Return a boolean indicating whether the disk is writable. =item C (Optional) sub can_flush { my $handle = shift; my $bool = ...; return $bool; } Return a boolean indicating whether flush can be performed. =item C (Optional) sub is_rotational { my $handle = shift; my $bool = ...; return $bool; } Return a boolean indicating whether the disk is rotational. =item C (Optional) sub can_trim { my $handle = shift; my $bool = ...; return $bool; } Return a boolean indicating whether trim/discard can be performed. =item C (Required) sub pread { my $handle = shift; my $count = shift; my $offset = shift; # Construct a buffer of length $count bytes and return it. return $buf; } The body of your C function should construct a buffer of length (at least) C<$count> bytes. You should read C<$count> bytes from the disk starting at C<$offset>. NBD only supports whole reads, so your function should try to read the whole region (perhaps requiring a loop). If the read fails or is partial, your function should C. =item C (Optional) sub pwrite { my $handle = shift; my $buf = shift; my $count = length ($buf); my $offset = shift; # No return value } The body of your C function should write the C<$buf> string to the disk. You should write C<$count> bytes to the disk starting at C<$offset>. NBD only supports whole writes, so your function should try to write the whole region (perhaps requiring a loop). If the write fails or is partial, your function should C. =item C (Optional) sub flush { my $handle = shift; # No return value } The body of your C function should do a L or L or equivalent on the backing store. If there is an error, the function should call C. =item C (Optional) sub trim { my $handle = shift; my $count = shift; my $offset = shift; # No return value } The body of your C function should "punch a hole" in the backing store. If there is an error, the function should call C. =back =head2 MISSING CALLBACKS =over 4 =item Missing: C and C These are not needed because you can just use regular Perl C and C constructs. =item Missing: C, C, C, C, C These are not yet supported. =back =head2 THREADS The thread model for Perl callbacks currently cannot be set from Perl. It is hard-coded in the C part to C. This may change or be settable in future. =head1 SEE ALSO L, L, L. =head1 AUTHORS Richard W.M.

Use the I<-r> (read-only) option to use this plugin safely if the disk image or virtual machine might be live. =head1 EXAMPLES Export the first partition I a disk image called C, and allow writes: nbdkit guestfs disk=disk.img export=/dev/sda1 Export a disk image which is located I a libvirt guest called C, read-only (I<-r> option): nbdkit -r guestfs domain=Guest mount=inspect export=/images/disk.img =head1 DESCRIPTION C is an L plugin that lets you access the contents of disk images over NBD. There are many weird and wonderful uses for this, and this man page only covers the simpler ones. The parameters control: =over 4 =item * Which disk(s) are added to libguestfs. Specifically C and C add a single disk or all the disks from a particular libvirt guest. =item * What, if any, filesystems inside the disk image / guest have to be mounted. Use C to do this automatically (like L I<-i> option), else mount individual filesystems. =item * What device or file I you want to export over NBD. Use C to specify the thing that you want to export. =item * Use the I<-r> option to export read-only. The default is read-write. =back =head1 PARAMETERS =over 4 =item B This optional parameter specifies the libvirt connection URI. This is only used with the C parameter. =item B Enable full debugging of libguestfs. Note you'll probably also have to use the L option I<-v> in order to see the messages. =item B Add the named disk image. You may specify this option multiple times. =item B Add the disk(s) from the libvirt guest called C. =item B Export C or C (from inside the disk image or guest) over NBD. Device names are the usual libguestfs names like C (meaning the first partition of the first disk), or C (a logical volume), or RAID arrays etc. The device name should not be confused with host devices. Filenames are similarly those located inside the guest or disk image, and always start with a C character (even for Windows guests). B. Use the I<-r> option to make them read-only. B. =item B This can be used to specify the format of the disk. Use it B the C argument. It works like the I<--format> option of L. =item B Use guest inspection to mount disks. This is like C. =item B =item B Mount C from inside the guest on C (defaults to C). This is like C. =item B Enable tracing of libguestfs calls. Note you'll probably also have to use the L option I<-v> in order to see the messages. =back =head1 WORKED EXAMPLES =head2 Exporting a partition or logical volume inside a disk image L is a host file that contains partitions or LVM logical volumes. Use the C option to add the disk. Because you don't want to access filesystem contents, C is not needed. nbdkit guestfs disk=disk.img export=/dev/sda1 nbdkit guestfs disk=disk.img export=/dev/VG/LV Use L to find out what devices, partitions, LVs, filesystems etc a disk image contains. =head2 Exporting a partition or logical volume inside guest L is the name (in libvirt) of a guest. Since the guest might be live, we use the I<-r> option to open the guest read-only. Because you don't want to access filesystem contents, C is not needed. nbdkit -r guestfs domain=Guest export=/dev/sda1 nbdkit -r guestfs domain=Guest export=/dev/VG/LV =head2 Exporting a file inside a disk image L is a partitioned disk image with one filesystem that contains a file that we want to export. Use the C option to add the disk, and C to specify the filesystem in the disk image. Use C to specify the name of the file in that filesystem that we want to export. nbdkit guestfs disk=disk.img mount=/dev/sda1 export=/image =head2 Exporting a file inside a virtual machine disk image L is the disk from a Windows virtual machine. Use the C option to add the disk, and C to auto-mount the filesystem(s) in the disk image. Use C to specify the name of the file from the guest that we want to export. nbdkit guestfs disk=windows.img mount=inspect \ export=/Users/rich/AppData/image =head1 DEBUGGING To debug this plugin, use the following options: nbdkit -f -v guestfs debug=1 trace=1 [...] This enables libguestfs debugging and tracing (see L). It also ensures that the messages are displayed by nbdkit (because of I<-f> and I<-v>). =head1 SEE ALSO L, L, L, L, L, L. =head1 AUTHORS Richard W.M.

Note this requires OCaml E 4.02.2, which has support for shared libraries. See L =head1 COMPILING AN OCAML NBDKIT PLUGIN After writing your OCaml plugin (C), link it using this command: ocamlopt.opt \ -output-obj -runtime-variant _pic \ -o nbdkit-myplugin-plugin.so \ NBDKit.cmx myplugin.ml \ -cclib -lnbdkitocaml You can then use C as if it were a regular nbdkit plugin (see L, L): nbdkit ./nbdkit-myplugin-plugin.so [args ...] or if the C<.so> file is installed in the C<$plugindir> directory: nbdkit myplugin [args ...] =head1 WRITING AN OCAML NBDKIT PLUGIN Broadly speaking, OCaml nbdkit plugins work like C ones, so you should read L first. You should also look at C which describes the plugin interface for OCaml plugins. Your OCaml code should call C like this: let plugin = { NBDKit.default_callbacks with NBDKit.name = "myplugin"; version = "1.0"; open_connection = Some myplugin_open; get_size = Some myplugin_get_size; pread = Some myplugin_pread; (* etc *) } let thread_model = NBDKit.THREAD_MODEL_SERIALIZE_CONNECTIONS let () = NBDKit.register_plugin thread_model plugin Your plugin can only call C once. =head2 HANDLE Your C callback can return an OCaml value of any type. The same value is passed back to the per-connection callbacks like C and C. Typically (although this is not a requirement) you define your own handle struct in your plugin: type handle = { (* any per-connection data you want to store goes here *) h_id : int; (* this is just an example field *) h_readonly : bool; } let id = ref 0 let myplugin_open readonly = (* return a newly allocated handle *) incr id; { h_id = !id; h_readonly = readonly } let myplugin_get_size handle = printf "handle ID = %d\n" handle.h_id; (* ... *) =head2 THREADS The first parameter of C is the thread model, which can be one of the values in the table below. For more information on thread models, see L. Note that because of the garbage collector lock in OCaml, callbacks are never truly concurrent. =over 4 =item C =item C =item C =item C =back =head1 SEE ALSO L, L, L. =head1 AUTHORS Richard W.M.

Currently it can only serve local VMDK files. The required C parameter should point to a VMDK file. It would be relatively simple to extend this plugin to access ESX servers or Virtual Center. The plugin can serve read-only (if the I<-r> option is used) or read/write. =head1 LIBRARY LOCATION If the VDDK library (C) is located on a non-standard path, you may need to set C or modify C before this plugin will work. The VDDK library may depend on C which you may have to install yourself. =head1 PARAMETERS =over 4 =item B This optional parameter lets you specify the name of the VDDK configuration file. =item B Set the name of the VMDK file to serve. This parameter is required. =item B This sets the path of the VMware VDDK library. It must be an absolute path. If the parameter is not given, then a hard-coded path determined at compile time is used. =back =head1 DEBUGGING VDDK Run nbdkit like this to see all debugging messages: nbdkit -f -v vddk file=FILENAME =head1 SEE ALSO L in the nbdkit source tree, L, L, L =head1 AUTHORS Richard W.M.

It serves the named C over NBD, uncompressing it on the fly. The plugin only supports read-only connections. =head2 GETTING BEST RANDOM ACCESS PERFORMANCE FROM XZ L files are split into streams and blocks. Most xz files contain only one stream which contains one or more blocks. You can find out how many streams and blocks are in an xz file by doing: $ xz --list winxp.img.xz Strms Blocks Compressed Uncompressed Ratio Check Filename 1 1 2,100.0 MiB 6,144.0 MiB 0.342 CRC64 winxp.img.xz ============= xz files are seekable on block boundaries only. Seeking is done by seeking directly to the lower block boundary, then (slowly) uncompressing data until the precise byte is reached. B To do this, use the I<--block-size> option with a small-ish block size. For example the same image as above compressed with a 16 MB block size: $ xz --best --block-size=16777216 winxp.img $ xz --list winxp.img.xz Strms Blocks Compressed Uncompressed Ratio Check Filename 1 384 2,120.1 MiB 6,144.0 MiB 0.345 CRC64 winxp.img.xz This file can be accessed randomly, and at most 16 MB of compressed data will have to be uncompressed to seek to any byte. Note as you would expect, xz cannot compress quite as efficiently when using a small block size. The space penalty in the above example is S 1%> of the compressed file size. =head1 PARAMETERS =over 4 =item B Serve the file named C. This parameter is required. =item B The maximum block size that the plugin will read. The plugin will refuse to read xz files that contain any block larger than this size. See the discussion above about creating xz files with small block sizes in order to reduce memory usage and increase performance. This parameter is optional. If not specified it defaults to 512M. =item B Maximum number of blocks stored in the LRU block cache. This parameter is optional. If not specified it defaults to 8. The plugin may allocate up to S bytes of memory I. =back =head1 SEE ALSO L, L, L. =head1 AUTHORS Richard W.M.

To test a plugin using libguestfs: - #include - Call: test_start_nbdkit (NBDKIT_PLUGIN ("name"), , NULL) at the beginning. This starts the nbdkit server. - Open a libguestfs handle, and configure the NBD client using: guestfs_add_drive_opts (g, "", GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw", GUESTFS_ADD_DRIVE_OPTS_PROTOCOL, "nbd", GUESTFS_ADD_DRIVE_OPTS_SERVER, server, -1); 'server' is a global that is initialized by 'test_start_nbdkit' and points to the nbdkit server socket. - Perform tests via libguestfs using the libguestfs device "/dev/sda", which corresponds to the NBD drive exposed by the plugin. - Close the handle and exit. An 'atexit' handler installed by 'test_start_nbdkit' cleans up the server automatically. For an example, see 'test-file.c'. nbdkit-1.1.11/tests/test.h0000664000175000017500000000416712162404416012273 00000000000000/* nbdkit * Copyright (C) 2013 Red Hat Inc. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions are * met: * * * Redistributions of source code must retain the above copyright * notice, this list of conditions and the following disclaimer. * * * Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. * * * Neither the name of Red Hat nor the names of its contributors may be * used to endorse or promote products derived from this software without * specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY RED HAT AND CONTRIBUTORS ''AS IS'' AND * ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, * THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A * PARTICULAR PURPOSE ARE DISCLAIMED.

Block devices are hard disks and things that behave like hard disks such as disk images and virtual machines. C is both a toolkit for creating NBD servers from "unconventional" sources and the name of an NBD server. To create a new Network Block Device source, all you need to do is write a few glue functions, possibly in C, or perhaps in a high level language like Perl or Python. The liberal licensing of nbdkit is meant to allow you to link nbdkit with proprietary libraries or to include nbdkit in proprietary code. If you want to write an nbdkit plugin, you should read L. Several plugins may be found in C<$libdir/nbdkit/plugins>. You can give the full path to the plugin, like this: nbdkit $libdir/nbdkit/plugins/nbdkit-file-plugin.so [...] but it is usually more convenient to use this equivalent syntax: nbdkit file [...] C<$libdir> is set at compile time. To print it out, do: nbdkit --dump-config =head1 EXAMPLES Serve file C on port 10809: nbdkit file file=disk.img Run the example1 plugin and connect to it using L: nbdkit example1 guestfish --ro -a nbd://localhost Run the example3 plugin and connect to it using L: nbdkit example3 size=1G guestfish --ro -a nbd://localhost To display usage information about a specific plugin: nbdkit --help example1 =head1 GLOBAL OPTIONS =over 4 =item B<--help> Display brief command line usage information and exit. =item B<--dump-config> Dump out the compile-time configuration values and exit. =item B<-f> =item B<--foreground> =item B<--no-fork> I fork into the background. =item B<-g> GROUP =item B<--group> GROUP Change group to C after starting up. A group name or numeric group ID can be used. The server needs sufficient permissions to be able to do this. Normally this would mean starting the server up as root. See also I<-u>. =item B<-i> IPADDR =item B<--ip-addr> IPADDR =item B<--ipaddr> IPADDR Listen on the specified interface. The default is to listen on all interfaces. See also I<-p>. =item B<-P> PIDFILE =item B<--pid-file> PIDFILE =item B<--pidfile> PIDFILE Write C (containing the process ID of the server) after nbdkit becomes ready to accept connections. If the file already exists, it is overwritten. nbdkit I delete the file when it exits. =item B<-p> PORT =item B<--port> PORT Change the TCP/IP port number on which nbdkit serves requests. The default is C<10809>. See also I<-i>. =item B<-r> =item B<--read-only> =item B<--readonly> The export will be read-only. If a client writes, then it will get an error. Note that some plugins inherently don't support writes. With those plugins the I<-r> option is added implicitly. Copy-on-write (or "snapshot") functionality is not supported by this server. However if you are using qemu as a client (or indirectly via libguestfs) then it supports snapshots. =item B<--run> CMD Run nbdkit as a captive subprocess of C. When C exits, nbdkit is killed. See L below. This option implies I<--foreground>. =item B<-s> =item B<--single> =item B<--stdin> Don't fork. Handle a single NBD connection on stdin/stdout. After stdin closes, the server exits. You can use this option to run nbdkit from inetd, systemd or similar superservers; or just for testing; or if you want to run nbdkit in a non-conventional way. This option implies I<--foreground>. =item B<-U> SOCKET =item B<--unix> SOCKET =item B<-U -> =item B<--unix -> Accept connections on the Unix domain socket C (which is a path). nbdkit creates this socket, but it will probably have incorrect permissions (too permissive). If it is a problem that some unauthorized user could connect to this socket between the time that nbdkit starts up and the authorized user connects, then put the socket into a directory that has restrictive permissions. nbdkit does B delete the socket file when it exits. The caller should delete the socket file after use (else if you try to start nbdkit up again you will get an C
error). If the socket name is I<-> then nbdkit generates a randomly named private socket. This is useful with L. =item B<-u> USER =item B<--user> USER Change user to C after starting up. A user name or numeric user ID can be used. The server needs sufficient permissions to be able to do this. Normally this would mean starting the server up as root. See also I<-g>. =item B<-v> =item B<--verbose> Enable verbose messages. It's a good idea to use I<-f> as well so the process does not fork into the background (but not required). =item B<-V> =item B<--version> Print the version number of nbdkit and exit. =back =head1 PLUGIN CONFIGURATION After specifying the plugin name you can (optionally, it depends on the plugin) give plugin configuration on the command line in the form of C. For example: nbdkit file file=disk.img To list all the options supported by a plugin, do: nbdkit --help file =head1 CAPTIVE NBDKIT You can run nbdkit as a "captive process", using the I<--run> option. This means that nbdkit runs as long as (for example) L or L is running. When those exit, nbdkit is killed. Some examples should make this clear. To run nbdkit captive under qemu: nbdkit file file=disk.img --run 'qemu -drive file=$nbd,if=virtio' On the qemu command line, C<$nbd> is substituted automatically with the right NBD path so it can connect to nbdkit. When qemu exits, nbdkit is killed and cleaned up automatically. Running nbdkit captive under guestfish: nbdkit file file=disk.img --run 'guestfish --format=raw -a $nbd -i' When guestfish exits, nbdkit is killed. The following shell variables are available in the I<--run> argument: =over 4 =item C<$nbd> A URL that refers to the nbdkit port or socket. Note there is some magic here, since qemu and guestfish URLs have a different format, so nbdkit tries to guess which you are running. If the magic doesn't work, try using the variables below instead. =item C<$port> If E "", the port number that nbdkit is listening on. =item C<$unixsocket> If E "", the Unix domain socket that nbdkit is listening on. =back I<--run> implies I<--foreground>. It is not possible, and probably not desirable, to have nbdkit fork into the background when using I<--run>. Even when running captive, nbdkit still listens on the regular TCP/IP port, unless you specify the I<-p>/I<-U> options. If you want a truly private captive nbdkit, then you should create a private random Unix socket, like this: nbdkit -U - plugin [args] --run '...' =head1 SIGNALS C responds to the following signals: =over 4 =item C =item C =item C The server exits cleanly. =item C This signal is ignored. =back =head1 SEE ALSO L, L, L, L, L, L, L, L, L, L, L, L.

This manual page describes how to create an nbdkit plugin in C. For example plugins, take a look at the source of nbdkit, in the C directory. To write plugins in other languages, see: L, L, L. =head1 C All plugins should start by including this header file: #include =head1 C<#define THREAD_MODEL> All plugins must define a thread model. See L below for details. It is generally safe to use: #define THREAD_MODEL NBDKIT_THREAD_MODEL_SERIALIZE_ALL_REQUESTS =head1 C All plugins must define and register one C, which contains the name of the plugin and pointers to callback functions. static struct nbdkit_plugin plugin = { .name = "myplugin", .longname = "My Plugin", .description = "This is my great plugin for nbdkit", .open = myplugin_open, .get_size = myplugin_get_size, .pread = myplugin_pread, .pwrite = myplugin_pwrite, /* etc */ }; NBDKIT_REGISTER_PLUGIN(plugin) The C<.name> field is the name of the plugin. The callbacks are described below (see L). Only C<.name>, C<.open>, C<.get_size> and C<.pread> are required. All other callbacks can be omitted. However almost all plugins should have a C<.close> callback. Most real-world plugins will also want to declare some of the other callbacks. The nbdkit server calls the callbacks in the following order over the lifetime of the plugin: =over 4 =item C<.load> is called once just after the plugin is loaded into memory. =item C<.config> and C<.config_complete> C<.config> is called zero or more times during command line parsing. C<.config_complete> is called once after all configuration information has been passed to the plugin. Both are called after loading the plugin but before any connections are accepted. =item C<.open> A new client has connected. =item C<.can_write>, C<.get_size> and other option negotiation callbacks These are called during option negotiation with the client, but before any data is served. =item C<.pread>, C<.pwrite> and other data serving callbacks After option negotiation has finished, these may be called to serve data. Depending on the thread model chosen, they might be called in parallel from multiple threads. =item C<.close> The client has disconnected. =item C<.open> ... C<.close> The sequence C<.open> ... C<.close> can be called repeatedly over the lifetime of the plugin, and can be called in parallel (depending on the thread model). =item C<.unload> is called once just before the plugin is unloaded from memory. =back =head1 ERROR HANDLING If there is an error in the plugin, the plugin should call C with the error message, and then return an error indication from the callback, eg. NULL or -1. C has the following prototype and works like L: void nbdkit_error (const char *fs, ...); =head1 FILENAMES AND PATHS The server usually (not always) changes directory to C before it starts serving connections. This means that any relative paths passed during configuration will not work when the server is running (example: S>). To avoid problems, prepend relative paths with the current directory before storing them in the handle. Or open files and store the file descriptor. =head2 C char *nbdkit_absolute_path (const char *filename); The utility function C converts any path to an absolute path. If conversion was not possible, this calls C and returns C. Note that this function does not check that the file exists. The returned string must be freed by the caller. =head1 CALLBACKS =head2 C<.name> const char *name; This field (a string) is required, and B contain only ASCII alphanumeric characters and be unique amongst all plugins. =head2 C<.version> const char *version; Plugins may optionally set a version string which is displayed in help and debugging output. =head2 C<.longname> const char *longname; An optional free text name of the plugin. This field is used in error messages. =head2 C<.description> const char *description; An optional multi-line description of the plugin. =head2 C<.load> void load (void); This is called once just after the plugin is loaded into memory. You can use this to perform any global initialization needed by the plugin. =head2 C<.unload> void unload (void); This may be called once just before the plugin is unloaded from memory. Note that it's not guaranteed that C<.unload> will always be called (eg. the server might be killed or segfault), so you should try to make the plugin as robust as possible by not requiring cleanup. =head2 C<.config> int config (const char *key, const char *value); On the nbdkit command line, after the plugin filename, come an optional list of C arguments. These are passed to the plugin through this callback when the plugin is first loaded and before any connections are accepted. This callback may be called zero or more times. Both C and C parameters will be non-NULL, but it is possible for either to be empty strings. The strings are owned by nbdkit but will remain valid for the lifetime of the plugin, so the plugin does not need to copy them. The format of the C accepted by plugins is up to the plugin, but you should probably look at other plugins and follow the same conventions. If the value is a relative path, then note that the server changes directory when it starts up. See L above. If the C<.config> callback is not provided by the plugin, and the user tries to specify any C arguments, then nbdkit will exit with an error. If there is an error, C<.config> should call C with an error message and return C<-1>. =head2 C<.config_complete> int config_complete (void); This optional callback is called after all the configuration has been passed to the plugin. It is a good place to do checks, for example that the user has passed the required parameters to the plugin. If there is an error, C<.config_complete> should call C with an error message and return C<-1>. =head2 C<.config_help> const char *config_help; This optional multi-line help message should summarize any C parameters that it takes. It does I need to repeat what already appears in C<.description>. If the plugin doesn't take any config parameters you should probably omit this. =head2 C<.open> void *open (int readonly); This is called when a new client connects to the nbdkit server. The callback should allocate a handle and return it. This handle is passed back to other callbacks and could be freed in the C<.close> callback. Note that the handle is completely opaque to nbdkit, but it must not be NULL. The C flag informs the plugin that the user requested a read-only connection using the I<-r> flag on the command line. Note that the plugin may I force the connection to be readonly (even if this flag is false) by returning false from the C<.can_write> callback. So if your plugin can only serve read-only, you can ignore this parameter. If there is an error, C<.open> should call C with an error message and return C. =head2 C<.close> void close (void *handle); This is called when the client closes the connection. It should clean up any per-connection resources. Note there is no way in the NBD protocol to communicate close errors back to the client, for example if your plugin calls L and you are checking for errors (as you should do). Therefore the best you can do is to log the error on the server. Well-behaved NBD clients I try to flush the connection before it is closed and check for errors, but obviously this is outside the scope of nbdkit. =head2 C<.get_size> int64_t get_size (void *handle); This is called during the option negotiation phase of the protocol to get the size (in bytes) of the block device being exported. The returned size must be E 0. If there is an error, C<.get_size> should call C with an error message and return C<-1>. =head2 C<.can_write> int can_write (void *handle); This is called during the option negotiation phase to find out if the handle supports writes. If there is an error, C<.can_write> should call C with an error message and return C<-1>. This callback is not required. If omitted, then we return true iff a C<.pwrite> callback has been defined. =head2 C<.can_flush> int can_flush (void *handle); This is called during the option negotiation phase to find out if the handle supports the flush-to-disk operation. If there is an error, C<.can_flush> should call C with an error message and return C<-1>. This callback is not required. If omitted, then we return true iff a C<.flush> callback has been defined. =head2 C<.is_rotational> int is_rotational (void *handle); This is called during the option negotiation phase to find out if the backing disk is a rotational medium (like a disk) or not (like an SSD). If true, this may cause the client to reorder requests to make them more efficient for a slow rotating disk. If there is an error, C<.is_rotational> should call C with an error message and return C<-1>. This callback is not required. If omitted, then we return false. =head2 C<.can_trim> int can_trim (void *handle); This is called during the option negotiation phase to find out if the plugin supports the trim/discard operation for punching holes in the backing storage. If there is an error, C<.can_trim> should call C with an error message and return C<-1>. This callback is not required. If omitted, then we return true iff a C<.trim> callback has been defined. =head2 C<.pread> int pread (void *handle, void *buf, uint32_t count, uint64_t offset); During the data serving phase, nbdkit calls this callback to read data from the backing store. C bytes starting at C in the backing store should be read and copied into C. nbdkit takes care of all bounds- and sanity-checking, so the plugin does not need to worry about that. The callback must read the whole C bytes if it can. The NBD protocol doesn't allow partial reads (instead, these would be errors). If the whole C bytes was read, the callback should return C<0> to indicate there was I error. If there is an error (including a short read which couldn't be recovered from), C<.pread> should call C with an error message and return C<-1>. =head2 C<.pwrite> int pwrite (void *handle, const void *buf, uint32_t count, uint64_t offset); During the data serving phase, nbdkit calls this callback to write data to the backing store. C bytes starting at C in the backing store should be written using the data in C. nbdkit takes care of all bounds- and sanity-checking, so the plugin does not need to worry about that. The callback must write the whole C bytes if it can. The NBD protocol doesn't allow partial writes (instead, these would be errors). If the whole C bytes was written successfully, the callback should return C<0> to indicate there was I error. If there is an error (including a short write which couldn't be recovered from), C<.pwrite> should call C with an error message and return C<-1>. =head2 C<.flush> int flush (void *handle); During the data serving phase, this callback is used to L the backing store, ie. to ensure it has been completely written to a permanent medium. If that is not possible then you can omit this callback. If there is an error, C<.flush> should call C with an error message and return C<-1>. =head2 C<.trim> int trim (void *handle, uint32_t count, uint64_t offset); During the data serving phase, this callback is used to "punch holes" in the backing store. If that is not possible then you can omit this callback. If there is an error, C<.trim> should call C with an error message and return C<-1>. =head1 THREADS Each nbdkit plugin must declare its thread safety model by defining the C macro. (This macro is used by C). The possible settings for C are defined below. =over 4 =item C<#define THREAD_MODEL NBDKIT_THREAD_MODEL_SERIALIZE_CONNECTIONS> Only a single handle can be open at any time, and all requests happen from one thread. Note this means only one client can connect to the server at any time. If a second client tries to connect it will block waiting for the first client to close the connection. =item C<#define THREAD_MODEL NBDKIT_THREAD_MODEL_SERIALIZE_ALL_REQUESTS> I. Multiple handles can be open at the same time, but data requests are serialized so that for the plugin as a whole only one read/write/etc request will be in progress at any time. This is a useful setting if the library you are using is not thread-safe. However performance may not be good. =item C<#define THREAD_MODEL NBDKIT_THREAD_MODEL_SERIALIZE_REQUESTS> Multiple handles can be open and multiple data requests can happen in parallel. However only one request will happen per handle at a time (but requests on different handles might happen concurrently). =item C<#define THREAD_MODEL NBDKIT_THREAD_MODEL_PARALLEL> Multiple handles can be open and multiple data requests can happen in parallel (even on the same handle). All the libraries you use must be thread-safe and reentrant. You may also need to provide mutexes for fields in your connection handle. =back If none of the above thread models are suitable, then use C and implement your own locking using C etc. =head1 PARSING SIZE PARAMETERS Use the C utility function to parse human-readable size strings such as "100M" into the size in bytes. int64_t nbdkit_parse_size (const char *str); C can be a string in a number of common formats. The function returns the size in bytes. If there was an error, it returns C<-1>. =head1 DEBUGGING Run the server with I<-f> and I<-v> options so it doesn't fork and you can see debugging information: nbdkit -fv ./myplugin.so [key=value [key=value [...]]] To print debugging information from within the plugin, call C, which has the following prototype and works like L: void nbdkit_debug (const char *fs, ...); Note that C only prints things when the server is in verbose mode (I<-v> option). =head1 INSTALLING THE PLUGIN The plugin is a C<*.so> file and possibly a manual page. You can of course install the plugin C<*.so> file wherever you want, and users will be able to use it by running: nbdkit /path/to/plugin.so [args] However B the shared library has a name of the form C-plugin.so> B the library is installed in the C<$plugindir> directory, then users can be run it by only typing: nbdkit name [args] The location of the C<$plugindir> directory is set when nbdkit is compiled and can be found by doing: nbdkit --dump-config =head1 WRITING PLUGINS IN OTHER PROGRAMMING LANGUAGES You can also write nbdkit plugins in OCaml, Perl or Python. Other programming languages may be offered in future. For more information see: L, L, L. =head1 SEE ALSO L, L, L, L, L, L, L. =head1 AUTHORS Richard W.M.
