RELEASE NOTES FOR LIBGUESTFS 1.24
These release notes only cover the differences from the previous stable/dev branch split
(1.22.0). For detailed changelogs, please see the git repository, or the ChangeLog file
distributed in the tarball.
Нові можливості
User-Mode Linux (UML) can be used as an alternative backend (ie. instead of KVM). This
improves performance especially when using libguestfs inside a VM (eg. in the cloud). UML
is supported as a first-class backend. See "USER-MODE LINUX BACKEND" in guestfs(3) for
how to use this.
ARM (32 bit) and PPC64 are now fully supported.
Інструменти
virt-builder(1) is a new tool for building virtual machine images. It lets you rapidly
and securely create guests and customize them.
New virt-sysprep(1) operations: Remove files in "/tmp" and "/var/tmp". Remove RPM
database files. Change root and user passwords. More log files are removed. New
operations which are not enabled by default: Create random UUIDs for filesystems. Reset
firewall rules. (Wanlong Gao)
virt-resize(1) and virt-sysprep can now use URIs to specify a remote disk.
Use "guestfish -N filename=type" to create a named disk image (instead of the default
"test1.img" etc).
virt-sparsify(1) now tests if there is enough disk space to complete the operation,
instead of possibly running out of space half way through.
virt-format(1) and virt-make-fs(1): new --label option for setting filesystem label.
virt-resize --no-sparse flag can be used to resize on to partitions and other targets that
are not zeroed.
Прив’язки до мов програмування
New bindings for the Go programming language.
API
Support for the systemd journal.
"guestfs_add_drive_opts" can now control the qemu caching mode through a new "cachemode"
parameter. You can select improved performance for temporary drives, or safety.
"guestfs_set_label" now works for XFS and btrfs.
New GUESTFS_EVENT_WARNING event for warning messages.
Inspection
Better inspection of SUSE guests (Olaf Hering).
Better support for non-standard Windows %systemroot% (Matthew Booth).
Enhanced error reporting for Augeas errors.

CVE-2013-2124
https://bugzilla.redhat.com/show_bug.cgi?id=968306
A denial of service was possible when inspecting certain guests. The fix has been
backported to 1.20 and 1.22 branches.
CVE-2013-4419
https://www.redhat.com/archives/libguestfs/2013-October/msg00031.html
Fix insecure temporary directory handling for remote guestfish. The fix has been
backported to 1.20 and 1.22 branches.

Build changes
The following packages are required to build libguestfs 1.24:
Augeas ≥ 1.0.0
The following optional packages may be added to enhance functionality but are not
required:
sd-journal
To read journal files from guests which use that.
url_mkcow
For UML backend.
curl
gpg
xz For virt-builder.
golang ≥ 1.1.1
For Go language bindings.
Внутрішня частина роботи програми
New "make check-*" rules replace "make extra-tests". See "make help" and guestfs(3) for
details.
Perl code can now be valgrinded.
Inspection code is now fuzz-tested.
"make" no longer recurses into the generator directory in every other directory. This
reduces the overhead of builds considerably.
Additional tests for Augeas, hivex.
Add a launch timeout of 20 minutes waiting for the appliance to start up.
Add a timeout (4 hours) to all tests so we can catch the case where qemu or other
components hang.
Use kvmclock and "-cpu host". This improves clock stability and overall performance.
"./configure --enable-packet-dump" mode is fixed.
"./configure --enable-valgrind-daemon" mode has been rewritten. It is now feasible for
developers to keep this flag enabled at all times.
Backends have been refactored to be modular (although they are not actually loadable
modules).
When enabled, the network now uses resolver configuration (ie. /etc/resolv.conf) from the
host.

НОТАТКИ ЩОДО ВИПУСКУ LIBGUESTFS 1.22
These release notes only cover the differences from the previous stable/dev branch split
(1.20.0). For detailed changelogs, please see the git repository, or the ChangeLog file
distributed in the tarball.
Нові можливості
API
Віддалений доступ до таких дисків:
• Network Block Device (nbd)
• Secure Shell (ssh)
• HTTP та HTTPS
• FTP та FTPS
• iSCSI
• Gluster
• Ceph/rbd (Mike Kelly)
• Sheepdog
• TFTP
The SYSLINUX and EXTLINUX bootloaders can now be installed in disk images using the API.
Inspection can now handle filesystems such as btrfs where subvolumes are separately
mountable (Matthew Booth).
"Attach methods" are now known as "backends". Compatibility with existing code is
preserved.
Filenames can contain ':', as long as newer QEMU is being used.
Інструменти
Virt-alignment-scan and virt-df scan multiple guests in parallel.
Guestmount now passes errno accurately back to userspace in almost all cases.
Guestfish and other tools can now use a URI-like syntax to access remote disks, eg:
guestfish -a ssh://example.com/path/to/disk.img
Guestfish and guestmount now allow you to specify the filesystem type when mounting, which
is more secure (Dave Vasilevsky).
Guestfish is now the "guest filesystem shell".
Guestfish allows only 1 "true" "t" "yes" "y" "on" 0 "false" "f" "no" "n" "off" for boolean
values (case insensitive), and gives an error for all other strings.
New tool "guestunmount" for unmounting FUSE filesystems safely.
"guestmount --no-fork" flag prevents guestmount from daemonizing.
Virt-resize now uses sparse copies by default, saving considerable space for guests which
are mostly empty.
Bash tab completion has been rewritten and can now handle most tools, and correctly tab-
complete "--long" options. In addition, bash completion scripts are loaded on demand.
Прив’язки до мов програмування
The Java API now supports events.
The Python object now inherits from the "object" base class.
Python methods which previously returned lists of tuples can now be made to return a
Python dict. For backwards compatibility, you have to enable this by using the
constructor option "guestfs.GuestFS (python_return_dict=True)".
The PHP bindings are now tested properly, and have had multiple fixes.
The long-deprecated Perl "Sys::Guestfs::Lib" library has been removed.
https://www.redhat.com/archives/libguestfs/2013-April/msg00001.html

The febootstrap tool has now been renamed to "supermin". Libguestfs can use either, but
now prefers "supermin". http://people.redhat.com/~rjones/supermin/
libxml2 is required to build libguestfs.
The hivexregedit program (from hivex) is required to build from git.
Internal functions can no longer be used unless the caller defines "-DGUESTFS_PRIVATE=1".
Enable C compiler warnings in Python, Ruby bindings.
Fail early and clearly if libvirt does not support qemu/KVM (eg. if default libvirt
connection is to Xen).
"make print-subdirs" rule, useful for selectively running tests.
Multiple fixes to allow separated (sourcedir != builddir) builds.
Декілька виправлень у прив’язках до Haskell.
"ln" and "ln-f" APIs now capture "errno" correctly.
Language binding tests use (mostly) a standard numbering scheme and aim to test the same
range of features in each language. Also the number of launches required has been reduced
so these tests should run much more quickly.
Library code internally uses GCC "__attribute__((cleanup))" (if available) to simplify
memory allocation.
Internal header files have been reorganized. See the comments in
"src/guestfs-internal*.h"
Internal code shared between the library and certain tools is now located in a static
"libutils" library.
Almost all subdirectories can now use parallel builds, although note that the top-level
directories still build in series.
Use of "PATH_MAX" and "NAME_MAX" has been eliminated from the code.
The Java API now requires JVM ≥ 1.6.
Force use of "serial-tests" with automake ≥ 1.12.
Use of sockets in the library protocol layer is abstracted, allowing other non-POSIX
layers to be added in future (see "src/conn-socket.c").
"qemu-img info --output json" is used if available, for more secure parsing of the output
of this command.
Distros can now use "make INSTALLDIRS=vendor install" to place Ruby bindings in vendordir.
This eliminates a non-upstream patch carried by both Fedora and Debian.
Valgrind log files are now written to "tmp/valgrind-DATE-PID.log"
"make clean" cleans the local "tmp/" directory.
The C API tests have been rewritten using a more flexible generator language that allows
arbitrary C code to be executing during tests.

НОТАТКИ ЩОДО ВИПУСКУ LIBGUESTFS 1.20
These release notes only cover the differences from the previous stable/dev branch split
(1.18.0). For detailed changelogs, please see the git repository, or the ChangeLog file
distributed in the tarball.
Нові можливості
libvirt і sVirt (контейнер SELinux)
You can optionally use libvirt to launch and manage the backend appliance by:
• встановленням "LIBGUESTFS_ATTACH_METHOD=libvirt[:URI]"
• за допомогою "./configure --with-default-attach-method=libvirt[:URI]"
• or calling the API method "guestfs_set_attach_method"
SVirt (SELinux confinement) is used to secure the libguestfs appliance, if the libvirt
backend is selected.
virtio-scsi, larger number of drives, hotplugging
Virtio-scsi is now used by default, if it is available. This greatly increases the number
of drives that can be added to a single libguestfs handle (up to 255).
You can now hotplug drives (add and remove drives after launch).
Libguestfs can now handle > 25 disks, in all APIs, tools and tests.
You can label drives when adding them, then refer to them by label
("/dev/disk/guestfs/LABEL") instead of having to use device names ("/dev/sda").
new library features
POSIX Access Control Lists (ACLs) and Linux filesystem capabilities can now be read and
written through the API.
Windows Dynamic Disks are now supported. The metadata can only be read (volumes cannot be
modified or created). However the data/filesystems in the volumes themselves can be
mounted, read and written (Matthew Booth).
Hivex (Windows Registry editing) is now directly supported through the API, making reading
or editing the Windows Registry much more efficient.
Several libguestfs APIs were reimplemented so they no longer have any limits on output.
The reimplemented APIs are: "guestfs_cat", "guestfs_find", "guestfs_read_file",
"guestfs_read_lines", "guestfs_write", "guestfs_write_append", "guestfs_lstatlist",
"guestfs_lxattrlist", "guestfs_readlinklist", "guestfs_ls".
virt tools
"guestfish touch 'win:c:\new_file'" now works as expected.
"guestfish" has a new --network option, which enables the user network in libguestfs.
You can set "GUESTFISH_PS1" to use fancy prompts in "guestfish".
"rsync", "ssh", "less" and "lrzip" commands are now available in virt-rescue. In
addition, "rsync" can be used through the API for doing incremental copies.
"virt-sparsify" uses qcow2 v3 for increased efficiency.
"virt-sysprep" enhancements:
• generate new UUIDs for PVs and VGs
• remove the local machine ID (Wanlong Gao)
• remove ABRT data (Wanlong Gao)
• remove puppet keys and log files (Wanlong Gao)
• remove process accounting files (Wanlong Gao)
• new --firstboot parameter allowing firstboot scripts for customizing guests
• remove HOSTNAME field from "ifcfg-eth*" files (Wanlong Gao)
• miscellaneous improvements for SuSE (Olaf Hering)
• remove man pages cache (Wanlong Gao)
• remove crash data generated by kexec-tools (Wanlong Gao)
"virt-make-fs" can now create virtual floppy disks (VFDs).
"guestmount" has a --pid-file option, which can be used to avoid a race condition between
unmounting the filesystem and using the underlying disk image.
прив’язки до мов програмування
Full-featured Lua bindings have been added in this release (thanks to Jerome Vuarand for
many suggestions).
In Ruby, optional arguments hash is optional.
In Python, optional arguments now don't use special "sentinel" values, so any integer can
be passed as an optional argument.
Erlang bindings now come with examples and tests.
Erlang bindings now handle 64 bit integer parameters correctly.
The automated 'bindtests' now test for 64 bit cleanliness in parameter passing. Several
bugs in the bindings were found and fixed as a result.
Better handling of blocking and non-blocking functions should make libguestfs calls more
efficient.
inspection
Windows guests with unlimited-sized Registries are now supported. By adding the hivex API
to the libguestfs API, it is much more efficient and easier to inspect and modify the
Windows Registry in guests.
Better support for SuSE guests (Olaf Hering).
Return the architecture of installed applications (John Eckersberg).
Windows 8 is now supported.
Тепер підтримується Fedora 18.
Inspection of ISOs/CDs/DVDs can now use the libosinfo database.
порти
Libguestfs without the appliance can be compiled on Mac OS X (Masami HIRATA).
RHEL 5 is now explicitly supported through the 'oldlinux' branch in upstream git.
PowerPC 64 bit is now supported. Also libguestfs has been examined for endianness bugs
and these have been fixed.
фонова служба
A man page for the daemon (guestfsd(8)) is included.
Безпека
guestfish history file
The "$HOME/.guestfish" history file is now created with 0600 permissions (instead of 0644
before) so it is no longer world readable.
CVE-2012-2690
Old versions of both "virt-edit" and the "guestfish" "edit" command created a new file
containing the changes but did not set the permissions, etc of the new file to match the
old one. The result of this was that if you edited a security sensitive file such as
"/etc/shadow" then it would be left world-readable after the edit.
Цій ваді було надано код CVE-2012-2690. Її було виправлено у libguestfs ≥ 1.16.

Внутрішня частина роботи програми
qemu ≥ 1.1 is required (≥ 1.2 preferred).
febootstrap ≥ 3.20 is required.
libvirt is optional, but if you want to use the new libvirt backend for launching the
appliance then libvirt ≥ 0.10.2 would be required.
Coverity has been run over the complete codebase, and many issues fixed (thanks Ondrej
Vasik, Kamil Dudka).
Functions which previously had no optargs can now be converted to ones with optargs,
making extending the API much more flexible. Source and binary backwards compatibility is
preserved for users of the API.
The way that libguestfs APIs and structures are represented in the generator has changed
to use an OCaml struct instead of a tuple. This makes generator descriptions more
flexible and easier to understand. For details see commits 39d1a7db and eb185eef.
Separation of the library code into more files:
• Launch backends are now located in separate files eg. "src/launch-appliance.c",
"src/launch-libvirt.c".
• Generated action code is now split over several "src/action*.c" files, for faster
compilation.
• The huge "src/guestfs.c" file is now split into smaller logical units.
POD (documentation) is now generated using a rewritten Perl program instead of pod2* +
shell scripts.
Man pages now contain stable dates (Hilko Bengen).
Skipped tests now exit with code 77, so they appear as "SKIP:" in "make check" output.
The parallel mount-local test has been rewritten in C (RHBZ#838081).
Ruby 1.8.5 is now supported (though Ruby ≥ 1.9 is preferred).
Perl bindings can be disabled via "./configure --disable-perl" (Wulf C. Krueger). Note
that Perl is still required in order to build libguestfs.
Java bindings are now enabled/disabled using "./configure --with-java" or "./configure
--without-java" (Wulf C. Krueger).
Нові параметри налаштування: "./configure --enable-code-profiling" і "./configure
--enable-code-coverage".
Multiple fixes to use of 64 bit integers in language bindings.
The appliance backend now uses sgabios instead of vgabios (Dan Berrange).
The "./run" script now sets enough environment variables that you can run OCaml, Python,
Ruby, Java, GJS, Erlang, Lua programs.
"./run --test" flag for running tests with minimal output. It also prints the time taken
to run each test.
The "./run" script now builds up paths cumulatively, meaning that you can use "./run"
twice, or use the libguestfs and libvirt "./run" scripts together.
You can extract a list of external commands required by the daemon, making building the
appliance on certain distros easier (Olaf Hering).
The "virt-rescue" command is now tested during "make check".
The generator now removes unused generated files. This helps when going back and forth
with git rebase, git bisect, etc.
Tests now run in a separate toplevel "tmp/" directory in the source. This allows the
directory to be labelled for SELinux (sVirt), and also makes it easier to clean up.
"make syntax-check" now works to a greater extent, and many problems in the main code that
were found by syntax-check have been fixed (thanks Jim Meyering).
Emacs mode (-*- foo -*-) has been added to generated files.
Progress bar output is now sent to "/dev/tty" so it doesn't end up in the regular output
of the program. virt-resize and virt-sparsify now suppress progress bars if stdout is not
a tty.
There is now a "./configure --without-libvirt" option. This is useful for testing that
the code still compiles without libvirt.
There is now an internal mini-library for running commands. This allows us to redirect
errors from external commands into events.
Code for handling temporary directories and the appliance cache was completely overhauled.
Code for temporarily ignoring/disabling errors now looks like this:
guestfs_push_error_handler (g, NULL, NULL);
guestfs_mkdir (g, "/foo"); /* We don't care if this fails. */
guestfs_pop_error_handler (g);
The "tests/extra" directory has gone. The "extra tests" are now split into separately
runnable targets, such as "make check-valgrind". Use "make help" to get a summary of the
targets.
The "lpj" option is passed to the appliance kernel when using TCG. This should improve
clock stability (thanks Marcelo Tosatti, Olaf Hering).

virt-alignment-scan is a new tool to check the alignment of
partitions within virtual machines or disk images.
virt-sparsify is a new tool to make virtual machine disk images
sparse.
virt-sysprep is a new tool to make cloning guests from a template
simpler.
guestfish
- New commands setenv, unsetenv, to set environment variables.
- The input file and line number is printed in error messages.
- guestfish progress bars are now a "mini-library" used by other
tools too.
guestmount
- the --live option (for access to live VMs) now works.
virt-cat

improving performance. The new virt-resize --align-first option
controls this behaviour.
- The virt-resize --machine-readable flag makes it possible to use
virt-resize from other programs.
- Partitions are now aligned to 128 sectors (usually 64K) by
default. This improves efficiency on high-end storage. The new
virt-resize --alignment option allows the alignment to be
adjusted.
virt-win-reg
