It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is # needed for multi-threaded programs (defaults to the value of CC # respectively CXX otherwise). (This is necessary on e.g. AIX to use the # special cc_r/CC_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also to link with them as well. For example, you might link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threaded programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # CXX="$PTHREAD_CXX" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to # that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

You must specify one input file, and one or more output formats. The output options are I<--man>, I<--html> and I<--text> (see below). In C files, use a variation of the boilerplate shown in the L section above. For information about the POD format, see L. =head1 OPTIONS =over 4 =cut my $help; =item B<--help> Display brief help. =cut my $allow_long_lines; =item B<--allow-long-lines> Allow lines longer than 76 characters in the input. Use this if the man page is not written by hand. =cut my $html; =item B<--html> output.html Write a web page to F. If this option is not given, then no web page output is produced. =cut my @inserts; =item B<--insert> filename:__PATTERN__ In the input file, replace the literal text C<__PATTERN__> with the replacement file F. You can give this option multiple times. The contents of F are treated as POD. Compare and contrast with I<--verbatim>. Although it is conventional to use C<__...__> (double underscores) for patterns, in fact you can use any string as the pattern. =cut my $man; =item B<--man> output.n Write a man page to F (C is the manual section number). If this option is not given, then no man page output is produced. =cut my $name; =item B<--name> NAME Set the name of the man page. If not set, defaults to the basename of the input file. =cut my @replaces; =item B<--replace> __PATTERN__:CONTENT In the input file, replace the literal text C<__PATTERN__> with the literal replacement string . You can give this option multiple times. Although it is conventional to use C<__...__> (double underscores) for patterns, in fact you can use any string as the pattern. =cut my $section; =item B<--section> N Set the section of the man page (a number such as C<1> for command line utilities or C<3> for C API documentation). If not set, defaults to C<1>. =cut my $text; =item B<--text> output.txt Write a text file to F. If this option is not given, then no text output is produced. =cut my @verbatims; =item B<--verbatim> filename:__PATTERN__ In the input file, replace the literal text C<__PATTERN__> with the replacement file F. You can give this option multiple times. The contents of F are inserted as verbatim text, and are I interpreted as POD. Compare and contrast with I<--insert>.

NBD — Network Block Device — is a protocol for accessing Block Devices (hard disks and disk-like things) over a Network. The key features of nbdkit are: * Multithreaded NBD server written in C with good performance. * Minimal dependencies for the basic server. * 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. Lets you export “unconventional†block devices easily. * You can write plugins in C/C++, Go, Lua, Perl, Python, OCaml, Rust, shell script or Tcl. * Filters can be stacked in front of plugins to transform the output. * Server can run standalone or can be invoked from other programs. For documentation, see the [docs directory](docs/). For plugins and filters, see the [plugins](plugins/) and [filters](filters/) directories. Example plugins can be found in `plugins/example*`. There are many NBD clients, but the nbdkit project has a companion client library called https://gitlab.com/nbdkit/libnbd Upstream repository: https://gitlab.com/nbdkit/nbdkit ## License This software is Copyright Red Hat and licensed under a BSD license. See [LICENSE](LICENSE) for details. Examples are usually licensed even more permissively ("as close to public domain as possible"), see the individual files for details. ## Building from source ### Requirements * Linux, macOS, Windows, FreeBSD, OpenBSD or Haiku * GCC or Clang * bash ≥ 4 * GNU make Recommended for TLS (authentication and encryption) support, but it is possible to build without it: * gnutls ≥ 3.5.18 For Windows support see [the Windows section below](README.md#windows). For macOS support see [the macOS section below](README.md#macos). ### Optional dependencies To build the man pages, you will optionally need to install: * Perl * `Pod::Man` and `Pod::Simple` (Perl libraries) For SELinux socket labelling support: * libselinux For the gzip filter, or for supporting compressed qcow2: * zlib or zlib-ng For the bzip2 filter: * bzip2 For the xz and lzip filters: * liblzma For the memory plugin with allocator=zstd, or for supporting compressed qcow2: * zstd For the curl (HTTP/FTP) plugin: * libcurl For the ssh plugin: * libssh ≥ 0.8.0 (this is a different library from libssh2 - that will not work) For the iso plugin: * xorriso or genisoimage or mkisofs For the floppy plugin: * iconv (on Linux this is built into glibc, on other systems it may be a separate library) For the libvirt plugin: * libvirt For the libguestfs plugin, and to run parts of the test suite: * libguestfs * guestfish (from libguestfs) For the ext2 filter: * ext2fs * com_err For the linuxdisk plugin: * mke2fs ≥ 1.42.10 (from e2fsprogs) For the nbd plugin, to get URI and TLS support, and also to run parts of the test suite: * libnbd ≥ 0.9.8 For the bittorrent plugin: * [libtorrent-rasterbar](https://www.libtorrent.org) For the blkio plugin: * [libblkio](https://libblkio.gitlab.io/libblkio) For the containerized data importer (CDI) plugin: * podman * jq For the Perl and example4 plugins: * perl interpreter * perl development libraries * perl module `ExtUtils::Embed` For the Python plugin: * python interpreter (version 3 only) * python development libraries * python unittest to run the test suite * boto3 is required to run the S3 plugin written in Python * google-cloud-storage is required to run the gcs plugin written in Python For the OCaml plugin: * OCaml ≥ 4.03 For the Tcl plugin: * Tcl development library and headers For the Lua plugin: * Lua development library and headers For the Rust plugin: * cargo (other dependencies will be downloaded at build time) For the golang plugin: * go ≥ 1.13 For bash tab completion: * bash-completion ≥ 1.99 To test for memory leaks (`make check-valgrind`): * valgrind program and development headers For non-essential enhancements to the test suite: * expect * fdisk, sfdisk (from util-linux) * flake8 * hexdump * ip, ss (from iproute package) * jq * libc_malloc_debug.so.0 (from glibc-utils) * losetup (from util-linux) * lzip * mke2fs (from e2fsprogs) * nbdcopy, nbdinfo, nbdsh (from libnbd) * qemu-img, qemu-io, qemu-nbd (usually shipped with qemu) * socat * stat (from coreutils) ### Building ``` autoreconf -i # only required when building from git clone ./configure make make check ``` On FreeBSD and OpenBSD which do not have GNU make by default you must use `gmake` instead of `make`. To run nbdkit from the source directory, use the top level ./nbdkit wrapper. It will run nbdkit and plugins from the locally compiled directory: ``` $ ./nbdkit example1 -f -v ./server/nbdkit ./plugins/example1/.libs/nbdkit-example1-plugin.so -f -v [etc] ``` Optionally run this command as root to install everything: ``` make install ``` ### Python Since nbdkit ≥ 1.16, only Python ≥ 3.6 is supported. By default nbdkit uses the Python version of the Python interpreter called “python†on the current $PATH. If you have parallel versions of Python installed then you can choose a different version by setting the PYTHON variable when configuring. For example: ``` ./configure PYTHON=/usr/bin/python3.8 ``` ### OCaml Most recent (less than, say, 8 years old) versions of the OCaml compiler should work. By default the configure script should detect the bytecode and native code compilers and enable either one or both. To enable OCaml warnings and turn them into hard errors (developers only): ``` ./configure OCAMLOPTFLAGS="-warn-error +A-3" ``` ### Running the tests To run the test suite: ``` make check ``` If there is a failure, look at the corresponding `tests/*.log` file for debug information. A few tests require root privileges, and are skipped by default. To run them you must do: ``` make check-root ``` If you have the proprietary VDDK library, you can test [nbdkit-vddk-plugin](plugins/vddk/) against the library like this: ``` make check-vddk vddkdir=vmware-vix-disklib-distrib ``` ### Running the benchmarks To run benchmarks: ``` make bench ``` ## Download tarballs Tarballs are available from: http://libguestfs.org/download/nbdkit ## Downstream packagers If you are packaging nbdkit, use: ``` ./configure --with-extra='...' ``` providing extra information about the distribution, and/or distro-specific versions. It helps us with troubleshooting bug reports. (Also, talk to us!) ## Developers Install the valgrind program and development headers. Use: ``` ./configure --enable-gcc-warnings --enable-valgrind ``` When testing use: ``` make check make check-valgrind ``` For development ideas, see the [TODO](TODO) file. The upstream git repository is: https://gitlab.com/nbdkit/nbdkit Please send patches to the libguestfs mailing list: https://lists.libguestfs.org For further information, see: https://libguestfs.org/ https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md ## Address sanitizer (ASAN) You can compile nbdkit with clang and ASAN with: ``` ./configure CC=clang CXX=clang++ \ CFLAGS="-O0 -g -fsanitize=address -fno-omit-frame-pointer" \ --disable-linker-script \ --disable-golang make clean make ASAN_OPTIONS="allocator_may_return_null=1:detect_leaks=0" make check ``` ## Test coverage ``` ./configure CFLAGS="--coverage -g" LDFLAGS="--coverage -g" make clean make make check lcov -c -d . -o gcov.info genhtml -o coverage gcov.info ``` Open your browser and examine the `coverage/` directory. At the time of writing (2024-05) test coverage of the server is reasonable, but things are much worse for certain plugins and filters. ## macOS nbdkit works on macOS and is mostly feature complete. Some tests may fail or be skipped. We have tested macOS 12 (Monterey), 13 (Ventura) and 14 (Sonoma), using MacPorts. Other versions of macOS and Homebrew may work too. We installed the following MacPorts packages: * autoconf * autoconf-archive * automake * bash * coreutils * gcc * gmake * gsed * jq * libtool * m4 * ocaml * pkg-config * qemu * ranlib We configured nbdkit using: ``` ./configure --enable-gcc-warnings --disable-perl \ CFLAGS="-g -O2 -I/opt/local/include" \ LDFLAGS="-L/opt/local/lib" ``` ## Windows Experimentally, the server can be compiled on Windows or cross-compiled from Linux using mingw-w64. Only a small subset of features are available. To find out what is missing read the TODO "Windows port". Note that GCC or Clang is required even if you are compiling on Windows because of some C language extensions we use. MSVC will not work. ### Cross-compiling from Linux to Windows For the rest of this section we talk about cross-compiling for Windows using Linux and mingw-w64. At a minimum you will need: * mingw-w64 gcc * mingw-w64 dlfcn * mingw-w64 winpthreads * mingw-w64 gnutls (optional, but highly recommended) * wine (if you want to run it on Linux) You may want to patch Wine with support for `AF_UNIX` sockets. It is needed to get most of the test suite to work, but if you don't care about the -U option then it is not needed. https://bugs.winehq.org/show_bug.cgi?id=52568 Other mingw-w64 libraries may be installed which will add functionality (see full list of requirements above), but you may end up hitting areas we have not compiled or tested before. To cross compile under Fedora or RHEL, ensure you have the following prerequisites: ``` dnf install -y mingw64-{gcc,dlfcn,winpthreads,gnutls} dnf install -y autoconf automake libtool make ``` then do: ``` autoreconf -i # when building from git mingw64-configure --disable-ocaml --disable-perl make ``` You can test if the server is working by doing: ``` ./nbdkit.exe --dump-config ``` (This usually runs wine automatically. If not, you may need to prefix the command "wine nbdkit.exe ...") To see which plugins and filters were compiled: ``` find plugins filters -name '*.dll' ``` You can run them under Wine without installing using eg: ``` ./nbdkit.exe -f -v memory 1G ``` You can run the test suite in the usual way: ``` make check ``` ### Running the cross-compiled binary on Windows To test the binary on a real Windows system you will need to copy server/.libs/nbdkit.exe, any plugins and filters you need (`plugins/*/.libs/*.dll` and `filters/*/.libs/*.dll`), and many mingw DLLs (`libdl.dll`, `libgnutls.dll`, `libwinpthread.dll`, etc.). Notes: 1. libtool creates files called nbdkit.exe in the top level directory and in [server](server/). These are the stripped binaries. The "real" binaries are located in hidden `.libs/` subdirectories. 2. The top level `.libs/nbdkit.exe` is the wrapper used to run nbdkit from the build directory, not the server binary. You need `server/.libs/nbdkit.exe` instead. 3. To find the list of mingw DLLs I ran nbdkit.exe iteratively until Windows stopped complaining about missing libraries. You could also use a tool like Dependency Walker. If you copy everything into a single directory on the Windows server then you should be able to run nbdkit normally, eg: ``` nbdkit.exe -f -v nbdkit-memory-plugin.dll 1G ``` You will probably need to open port 10809 on the Windows Firewall. nbdkit-1.42.4/TODO0000644000175000017500000004343515021322712007232 To-do list for nbdkit ====================================================================== General ideas for improvements ------------------------------ * Listen on specific interfaces or protocols. * Performance - measure and improve it. Chart it over various buffer sizes and threads, as that should make it easier to identify systematic issues. * For parallel plugins, only create threads on demand from parallel client requests, rather than pre-creating all threads at connection time, up to the thread pool size limit. Of course, once created, a thread is reused as possible until the connection closes. * A new threading model, SERIALIZE_RETIREMENT, which lets the client queue up multiple requests and processes them in parallel in the plugin, but where the responses sent back to the client are in the same order as the client's request rather than the plugin's completion. This is stricter than fully parallel, but looser than SERIALIZE_REQUESTS (in particular, a client can get non-deterministic behavior if batched requests touch the same area of the export). * Async callbacks. The current parallel support requires one thread per pending message; a solution with fewer threads would split low-level code between request and response, where the callback has to inform nbdkit when the response is ready: https://www.redhat.com/archives/libguestfs/2018-January/msg00149.html * More NBD protocol features. The currently missing features are structured replies for sparse reads, and online resize. * Test that zero-length read/write/extents requests behave sanely (NBD protocol says they are unspecified). * If a client negotiates structured replies, and issues a read/extents call that exceeds EOF (qemu 3.1 is one such client, when nbdkit serves non-sector-aligned images), return the valid answer for the subset of the request in range and then NBD_REPLY_TYPE_ERROR_OFFSET for the tail, rather than erroring the entire request. * Audit the code base to get rid of strerror() usage (the function is not thread-safe); however, using strerror_r() can be tricky as it has a different signature in glibc than in POSIX. * Teach nbdkit_error() to have smart newline appending (for existing inconsistent clients), while fixing internal uses to omit the newline. Commit ef4f72ef has some ideas on smart newlines, but that should probably be factored into a utility function. * Add a mode of operation where nbdkit is handed a pre-opened fd to be used immediately in transmission phase (skipping handshake). There are already third-party clients of the kernel's /dev/nbdX which rely on their own protocol instead of NBD handshake, before calling ioctl(NBD_SET_SOCK); this mode would let the third-party client continue to keep their non-standard handshake while utilizing nbdkit to prototype new behaviors in serving the kernel. * "nbdkit.so": nbdkit as a loadable shared library. The aim of nbdkit is to make it reusable from other programs (see nbdkit-captive(1)). If it was a loadable shared library it would be even more reusable. API would allow you to create an nbdkit instance, configure it (same as the current command line), start it serving on a socket, etc. However perhaps the current ability to work well as a subprocess is good enough? Also allowing multiple instances of nbdkit to be loaded in the same process is probably impossible. * password=- to mean read a password interactively from /dev/tty (not stdin). * Add separate man pages for a few missing NBDKIT_EXTERN_DECL functions, including those for extents, contexts, and exports. * Enhance --keepalive by allowing more socket options to be set, in particular SOL_TCP + TCP_KEEPCNT, SOL_TCP + TCP_KEEPIDLE, and SOL_TCP + TCP_KEEPINTVL. * Fix --port=0 / allow nbdkit to choose a TCP port: Several tests rely on picking a random TCP port, which is racy. The kernel can pick a port for us, and nbdkit --print-uri function can be used to display the random port to the user. Because of a bug, nbdkit lets you choose --port=0, causing the kernel to pick a port, but --print-uri doesn't display the port, and a different port is picked for IPv4 and IPv6 (so it only makes sense to use this with -4 or -6 option). Once this mess is fixed, the tests should be updated to use this. Suggestions for plugins ----------------------- Note: qemu supports other formats such as iscsi and ceph/rbd, and while similar plugins could be written for nbdkit there is no compelling reason unless the result is better than qemu-nbd. For the majority of users it would be better if they were directed to qemu-nbd for these use cases. * XVA files https://lists.gnu.org/archive/html/qemu-devel/2017-11/msg02971.html is a partial solution but it needs cleaning up. nbdkit-floppy-plugin: * Add boot sector support. In theory this is easy (eg. using SYSLINUX), but the practical reality of making a fully bootable floppy is rather more complex. * Add multiple dir merging. nbdkit-linuxdisk-plugin: * Add multiple dir merging (in e2fsprogs mke2fs). VDDK: * Map export name to file parameter, allowing clients to access multiple disks from a single VM. * For testing VDDK, try to come up with delay filter + sparse plugin settings which behave closely (in terms of performance and API latency) to the real thing. This would allow us to tune some performance tools without needing VMware all the time. nbdkit-torrent-plugin: * There are lots of settings we could map into parameters: https://www.libtorrent.org/reference-Settings.html#settings_pack * The C++ could be a lot more natural. At the moment it's a kind of “C with C++ extensionsâ€. nbdkit-ondemand-plugin: * Implement more callbacks, eg. .zero * Allow client to select size up to a limit, eg. by sending export names like ‘export:4G’. This would have to be controlled by a flag, since existing clients might be using ':'. nbdkit-data-plugin: * Allow expressions to evaluate to numbers, offsets, etc so that this works: nbdkit data '(0x55 0xAA)*n' n=1000 * Allow inclusion of files where the file is not binary but is written in the data format. * Like $VAR but the variable is either binary or base64. nbdkit-cdi-plugin: * Look at using skopeo instead of podman pull (https://github.com/containers/skopeo) nbdkit-blkio-plugin: * Use event-driven mode instead of blocking mode. This involves restructuring the plugin so that there is one or more background threads to handle the events, and nbdkit threads issue requests to these threads. (See how it is done in the VDDK plugin.) nbdkit-file-plugin: * There are multiple issues with handling block devices, zeroing and trimming: - Extents don't work at all (eg. for LVM thin devices). There's no way to fix this in the current Linux kernel. Likely requires a patch such as: https://lkml.org/lkml/2024/3/28/1165 - Alignment of discard and zero requests may be an issue, since the code currently assumes that sector alignment is always fine, but there may be block devices with larger alignment requirements. - We're waiting for Linux to allow fallocate(FALLOC_FL_PUNCH_HOLE) on all block device types (including LVM thin). There are some proposals upstream. This would allow us to remove the BLKDISCARD code and simplify things. - Can we be guaranteed that in all paths through `file_zero`, when trimming, reads will always return zeroes? Requires code review. - For more, see comments in https://gitlab.com/nbdkit/nbdkit/-/merge_requests/88 Suggestions for language plugins -------------------------------- Python: * Get the __docstring__ from the module and print it in --help output. This requires changes to the core API so that config_help is a function rather than a variable (see V3 suggestions below). Suggestions for filters ----------------------- * Add shared filter. Take advantage of filter context APIs to open a single context into the backend shared among multiple client connections. This may even allow a filter to offer a more parallel threading model than the underlying plugin. * CBT filter to track dirty blocks. See these links for inspiration: https://www.cloudandheat.com/block-level-data-tracking-using-davice-mappers-dm-era/ https://github.com/qemu/qemu/blob/master/docs/interop/bitmaps.rst * masking plugin features for testing clients (see 'nozero' and 'fua' filters for examples) * "bandwidth quota" filter which would close a connection after it exceeded a certain amount of bandwidth up or down. * "forward-only" filter. This would turn random access requests from the client into serial requests in the plugin, meaning that the plugin could be written to assume that requests only happen from beginning to end. This is would be useful for plugins that have to deal with non-seekable compressed data. Note the filter would have to work by caching already-read data in a temporary file. * nbdkit-cache-filter should handle ENOSPC errors automatically by reclaiming blocks from the cache * nbdkit-cache-filter could use a background thread for reclaiming. * zstd filter was requested as a way to do what we currently do with xz but saving many hours on compression (at the cost of hundreds of MBs of extra data) https://github.com/facebook/zstd/issues/395#issuecomment-535875379 * nbdkit-exitlast-filter could probably use a configurable timeout so that there is a grace period in case another connection comes along. * nbdkit-pause-filter would probably be more useful if the filter could inject a flush after pausing. However this requires that filter background threads have access to the plugin (see above). nbdkit-luks-filter: * This filter should also support LUKSv2 (and so should qemu). * There are some missing features: ESSIV, more ciphers. * Implement trim and zero if possible. nbdkit-readahead-filter: * The filter should open a new connection to the plugin per background thread so it is able to work with plugins that use the serialize_requests thread model (like curl). At the moment it makes requests on the same connection, so it requires plugins to use the parallel thread model. * It should combine (or avoid) overlapping cache requests. nbdkit-rate-filter: * allow other kinds of traffic shaping such as VBR * limit traffic per client (ie. per IP address) * split large requests to avoid long, lumpy sleeps when request size is much larger than rate limit nbdkit-retry-filter: * allow user to specify which errors cause a retry and which ones are passed through; for example there's probably no point retrying on ENOMEM * there are all kinds of extra complications possible here, eg. specifying a pattern of retrying and reopening: retry-method=RRRORRRRRORRRRR meaning to retry the data command 3 times, reopen, retry 5 times, etc. * subsecond times nbdkit-ip-filter: * permit hostnames and hostname wildcards to be used in the allow and deny lists * the allow and deny lists should be updatable while nbdkit is running, for example by storing them in a database file nbdkit-extentlist-filter: * read the extents generated by qemu-img map, allowing extents to be ported from a qemu block device * make non-read-only access safe by updating the extent list when the filter sees writes and trims nbdkit-exportname-filter: * find a way to call the plugin's .list_exports during .open, so that we can enforce exportname-strict=true without command line redundancy * add a mode for passing in a file containing exportnames in the same manner accepted by the sh/eval plugins, rather than one name (and no description) per config parameter nbdkit-evil-filter: * improve the algorithm so it can simulate bursts of corrupted bits (https://listman.redhat.com/archives/libguestfs/2023-May/031567.html) nbdkit-qcow2dec-filter: * implement extents - we know which clusters are preallocated and sparse, so map that into extent information * implement internal snapshots - it should be possible to select an internal snapshot by name nbdkit-spinning-filter: * fix multiconn / multiple connections so there is a single view of heads across all NBD clients nbdkit-time-limit-filter: * start counting at preconnect * fix idle connection issue mentioned in the man page * separate overall time limit and idle time limit Filters for security -------------------- Things like filtering by IP address can be done using external wrappers (TCP wrappers, systemd), or nbdkit-ip-filter. However it might be nice to have a configurable filter for preventing valid but not sensible requests. The server already filters invalid requests. This would be like seccomp, and could be implemented using an eBPF-based parser. Unfortunately actual eBPF is difficult to use for userspace processes. The "standard" isn't solidly defined - the Linux kernel implementation is the standard - and Linux has by far the best implementation, particularly around bytecode verification and JITting. There is a userspace VM (ubpf) but it has very limited capabilities compared to Linux. Composing nbdkit ---------------- Filters allow certain types of composition, but others would not be possible, for example RAIDing over multiple nbd sources. Because the plugin API limits us to loading a single plugin to the server, the best way to do this (and the most robust) is to compose multiple nbdkit processes. Perhaps libnbd will prove useful for this purpose. Build-related ------------- * Figure out how to get 'make distcheck' working. VPATH builds are working, but various pkg-config results that try to stick bash-completion and ocaml add-ons into their system-wide home do not play nicely with --prefix builds for a non-root user. * Right now, 'make check' builds keys with an expiration of 1 year only if they don't exist, and we leave the keys around except under 'make distclean'. This leads to testsuite failures when (re-)building in an incremental tree first started more than a year ago. Better would be having make unconditionally run the generator scripts, but tweak the scripts themselves to be a no-op unless the keys don't exist or have expired. Windows port ------------ Currently many features are missing, including: * Daemonization. This is not really applicable for Windows where you would instead want to run nbdkit as a service using something like SRVANY. You must use the -f option or one of the other options that implies -f. * These options are all unimplemented: --exit-with-parent, --group, --run, --selinux-label, --single, --swap, --user, --vsock * Many other plugins and filters. * errno_is_preserved should use GetLastError and/or WSAGetLastError but currently does neither so errors from plugins are probably wrong in many cases. * Most tests are skipped because of the missing features above. V3 plugin protocol ------------------ From time to time we may update the plugin protocol. This section collects ideas for things which might be fixed in the next version of the protocol. Note that we keep the old protocol(s) around so that source compatibility is retained. Plugins must opt in to the new protocol using ‘#define NBDKIT_API_VERSION ’. * All methods taking a ‘count’ field should be uint64_t (instead of uint32_t). Although the NBD protocol does not support 64 bit lengths, it might do in future. * v2 .can_zero is tri-state for filters, but bool for plugins; in v3, even plugins should get a say on whether to emulate * v2 .can_extents is bool, and cannot affect our response to NBD_OPT_SET_META_CONTEXT (that is, we are blindly emulating extent support regardless of the export name). In v3, .can_extents should be tri-state, with an explicit way to disable that context on a per-export basis. * pread could be changed to allow it to support Structured Replies (SRs). This could mean allowing it to return partial data, holes, zeroes, etc. For a client that negotiates SR coupled with a plugin that supports .extents, the v2 protocol would allow us to at least synthesize NBD_REPLY_TYPE_OFFSET_HOLE for less network traffic, even though the plugin will still have to fully populate the .pread buffer; the v3 protocol should make sparse reads more direct. * Parameters should be systematized so that they aren't just (key, value) strings. nbdkit should know the possible keys for the plugin and filters, and the type of the values, and both check and parse them for the plugin. * Modify open() API so it takes an export name and tls parameter. * Modify get_ready() API to pass final selected thread model. Filters already get this information, but to date, we have not yet seen a reason to add nbdkit_get_thread_model for use by v2 plugins. * Change config_help from a variable to a function. * Consider extra parameters to .block_size(). First so that we can separately control maximum data request (eg. pread) vs maximum virtual request (eg. zero). Note that the NBD protocol does not yet support this distinction. We may also need a 'bool strict' parameter to specify whether the client requested block size information or not. qemu-nbd can distinguish these two cases. * Renumber thread models. Redefine existing thread models like this: model existing value new value SERIALIZE_CONNECTIONS 0 1000 SERIALIZE_ALL_REQUESTS 1 2000 SERIALIZE_REQUESTS 2 3000 PARALLEL 3 4000 This allows new thread models to be inserted before and between the existing ones. In particular SERIALIZE_RETIREMENT has been suggested above (inserted between SERIALIZE_REQUESTS and PARALLEL). We could also imagine a thread model more like the one VDDK really wants which calls open and close from the main thread. For backwards compatibility the old numbers 0-3 can be transparently mapped to the new values. nbdkit-1.42.4/compile0000755000175000017500000001670514751341022010124 #! /bin/sh # Wrapper for compilers which do not understand '-c -o'. scriptversion=2024-06-19.01; # UTC # Copyright (C) 1999-2024 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program 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, 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.
