    guestfs-release-notes - libguestfs Release Notes

RELEASE NOTES FOR LIBGUESTFS 1.30

    These release notes only cover the differences from the previous
    stable/dev branch split (1.28.0). For detailed changelogs, please see
    the git repository, or the ChangeLog file distributed in the tarball.

 New features

  New tools

    virt-dib(1) is a secure and safe alternative to the OpenStack
    "diskimage-builder" tool. It is compatible with diskimage-builder
    elements. (Pino Toscano)

    virt-get-kernel(1) extracts the kernel and ramdisk from a disk image.
    Previously this functionality was part of virt-builder(1), but the new
    tool is more featureful. (Pino Toscano)

  New features in existing tools

    virt-v2v(1) -i ova mode can now read a wider range of OVA files, and
    also unpacked files (directories).

    virt-v2v now securely passes options to curl, so passwords, cookies and
    so on cannot be seen by users with shell access on the same machine.

    virt-v2v has a new --password-file option to allow you to securely pass
    in a password, and to avoid an interactive prompt.

    virt-v2v disables Windows autoreboot, making debugging conversion
    failures on Windows easier.

    virt-v2v now comes with an extensive external test suite. See
    virt-v2v-test-harness(1).

    virt-v2v allows virtio drivers to come from any location (Roman Kagan),
    and drivers can be read directly from the virtio ISO.

    virt-v2v supports conversion of Windows ≥ 8. Note this is experimental,
    and possibly broken. Use with caution.

    virt-v2v can now convert UEFI guests.

    virt-p2v(1) adds a network configuration dialog.

    virt-p2v now has p2v.pre, p2v.post and p2v.fail triggers, allowing
    arbitrary scripts for preparing the host for conversion and tidying up
    post-conversion.

    virt-p2v now uses the more advanced metacity window manager (instead of
    matchbox).

    virt-sysprep(1) will remove /var/spool/mail/username for non-root
    accounts (Hu Tao).

    virt-customize(1), virt-builder(1) and virt-sysprep have the following
    new options:

    --commands-from-file

      allow long lists of commands to be read from a file instead of from
      the command line (Pino Toscano)

    --copy

      copy files inside the guest (Maros Zatko)

    --copy-in

      copy host files recursively into the guest (Pino Toscano)

    --move

      move files inside the guest (Maros Zatko)

    --ssh-inject

      inject SSH keys into a guest (Pino Toscano)

    --sm-attach

    --sm-credentials

    --sm-register

    --sm-remove

    --sm-unregister

      register and unregister a guest from subscription-manager (Pino
      Toscano)

    --touch

      touch a file in the guest (Pino Toscano)

    --truncate

    --truncate-recursive

      truncate files (Maros Zatko)

    Improvements to virt-customize firstboot support. In particular,
    Windows firstboot should work as well as Linux (Roman Kagan).

    virt-df(1) can now use PolicyKit, SASL and other authentication methods
    when getting the list of domains from libvirt.

    Improvements to guestfish bash completion (Pino Toscano).

    Bash completion now completes short options as well as long options
    (Pino Toscano).

    guestfish(1) now displays a command synopsis if the number of
    parameters given to a command is wrong (Hu Tao).

    virt-builder now supports Red Hat Enterprise Linux versions back to
    RHEL 3.

    virt-builder supports SUSE guests using zypper (Cédric Bosdonnat).

  Language bindings

    The Java bindings now include validated Javadoc, and other improvements
    (Pino Toscano).

    Multiple fixes and improvements to the PHP bindings (Pino Toscano).

  Inspection

    Inspection can now get icons from RHEL 7 and CentOS 7.

    /etc/favicon.png is now allowed to be a symbolic link.

    For RPM-based guests, inspection now returns RPM Epoch fields.

    Debian packages now have separate Epoch and Version fields (Nikos
    Skalkotos).

    OpenBSD detection added, FreeBSD and NetBSD added as separate
    "distros", and other BSD inspection improvements and bug fixes (Nikos
    Skalkotos).

    CoreOS detection added (Nikos Skalkotos).

    The package manager in Fedora ≥ 22 is dnf.

    ReactOS guests can be inspected (Maros Zatko).

    Add support for UEFI guests.

    Inspection now works when kernel modules are gzip or xz compressed
    (Pino Toscano).

    Inspection now recognizes ppc64 and ppc64le guests (Maros Zatko).

    Inspection lists the installed applications on Archlinux guests (Nikos
    Skalkotos).

  Architectures and platforms

    PPC64 (POWER7) and PPC64LE (POWER8) architectures are now much better
    supported, and should work out of the box.

    For aarch64, we use AAVMF (an open source UEFI implementation based on
    OVMF) if available to run the appliance.

    For armv7, we now use the -M virt machine type by default.

    There is better support for compiling on non-Linux platforms (Pino
    Toscano, Margaret Lewicka).

    Libguestfs should now work on MIPS 32 bit little endian ("mipsel"). I
    have not been able to try 64 bit or big endian.

 Security

    CVE-2014-8484

    CVE-2014-8485

      Libguestfs previously ran the strings(1) utility on untrusted files.
      Strings could parse BFD headers in an unsafe way, leading to possible
      arbitrary code execution. Libguestfs now runs strings with a flag to
      ensure it does not try to parse BFD headers. This could have led to
      exploitation of the libguestfs appliance, but since libguestfs
      further constrains the appliance through virtualization, SELinux and
      other techniques, it was unlikely to have caused any privilege
      escalation on the host.

    XPath injection in virt-v2v

      One possible XPath injection vulnerability was fixed in virt-v2v.
      This might have allowed a malicious guest which was being converted
      by virt-v2v to construct an arbitrary XPath expression which would
      have been evaluated on the host (by the libxml2 library linked to the
      virt-v2v binary). It is not clear what the effects of this might be.

      For further information, see upstream commit
      https://github.com/libguestfs/libguestfs/commit/6c6ce85f94c36803fe2db35a98db436bff0c14b0

    Denial of service problems when using qemu-img info

      When using the American Fuzzy Lop fuzzer (afl-fuzz) on the qemu-img
      info command, Richard W.M. Jones found that certain files can cause
      the qemu-img program to use lots of memory and time (for example 6GB
      of heap and 14 seconds of CPU time on a fast Intel processor), and in
      some cases to crash. Since libguestfs may run qemu-img info on disk
      images to find out what they contain, this transitively could cause
      libguestfs to hang or consume lots of memory.

      Libguestfs was modified so that it uses resource limits to limit the
      space and time used by qemu-img info, to avoid this problem. If a
      malicious user tries to pass one of these disk images to libguestfs,
      qemu-img will crash and the crash is reported back to libguestfs
      callers as an error message.

 API

  New APIs

    guestfs_add_libvirt_dom

      This exposes a previously private API that allows you to pass a
      virDomainPtr object directly from libvirt to libguestfs.

    guestfs_blockdev_setra

      Adjust readahead parameter for devices. See blockdev --setra command.

    guestfs_btrfs_balance

      Restore superblocks in Btrfs filesystems (Hu Tao).

    guestfs_btrfs_replace

      Replace a device in a Btrfs filesystem (Cao Jin).

    guestfs_btrfs_scrub

    guestfs_btrfs_scrub_cancel

    guestfs_btrfs_scrub_resume

    guestfs_btrfs_scrub_status

      Scrub a Btrfs filesystem (Hu Tao).

    guestfs_btrfs_subvolume_get_default

      Get the default subvolume of a Btrfs filesystem (Hu Tao).

    guestfs_btrfs_subvolume_show

      List detailed information about the subvolume of a Btrfs filesystem
      (Hu Tao).

    guestfs_btrfstune_enable_extended_inode_refs

    guestfs_btrfstune_enable_skinny_metadata_extent_refs

    guestfs_btrfstune_seeding

      Various tuning parameters for Btrfs filesystems (Chen Hanxiao).

    guestfs_c_pointer

      Return the C pointer to the underlying guestfs_h *. This allows
      interworking of libguestfs bindings with bindings from other
      libraries. For further information see
      https://bugzilla.redhat.com/1075164

    guestfs_copy_in

    guestfs_copy_out

      Flexible APIs for recursively copying directories of files between
      the host and guest filesystem. Previously these were available only
      as guestfish commands, but now any API users can call them (Pino
      Toscano).

    guestfs_part_get_gpt_guid

    guestfs_part_set_gpt_guid

      Get and set the GPT per-partition GUID.

    guestfs_part_get_mbr_part_type

      Get MBR partition type (Chen Hanxiao).

    guestfs_set_uuid_random

      Set the UUID of a filesystem to a randomly generated value; supported
      filesystems currently are ext2/3/4, XFS, Btrfs, and swap partitions.
      (Chen Hanxiao).

  Other API changes

    guestfs_disk_create can now use VMDK files as backing files.

    guestfs_btrfs_subvolume_snapshot takes extra optional parameters (all
    added by Hu Tao):

    ro

      for creating a read-only Btrfs snapshot

    qgroupid

      for adding the snapshot to a qgroup

    guestfs_btrfs_subvolume_create can also take the optional qgroupid
    parameter (Hu Tao).

    guestfs_set_uuid can set UUID of swap partitions, Btrfs (Hu Tao, Chen
    Hanxiao).

    guestfs_copy_device_to_file and guestfs_copy_file_to_file have a new
    optional append parameter, allowing you to append to the output file
    instead of truncating it.

    guestfs_mkfs has a new optional label parameter to set the initial
    label of the new filesystem (Pino Toscano).

    guestfs_set_label and guestfs_set_uuid now set ENOTSUP as errno when
    there is no implemented support for the filesystem of the specified
    mountable (Chen Hanxiao).

    Environment variables now let you write LIBGUESTFS_DEBUG=true,
    LIBGUESTFS_DEBUG=0 and so on.

    All guestfs_sfdisk* APIs have been deprecated. Because sfdisk(8) was
    rewritten, incompatibly, upstream, we don't recommend using these APIs
    in future code. Use the guestfs_part* APIs as replacements.

    APIs such as guestfs_download do not truncate /dev/stdout or
    /dev/stderr when writing to them, meaning that if you redirect stdout
    or stderr to a file, the file is no longer truncated.

 Build changes

    The daemon no longer uses its own separate copy of gnulib. Instead it
    shares a single copy with the library.

    OCaml .annot files are now created, so IDEs and editors like emacs and
    vi can browse OCaml types in the source code.

    Various fixes to allow different host/appliance architecture builds
    (Pino Toscano).

    Automake is now used directly to build all the OCaml programs, instead
    of ad hoc Makefile rules. One side effect of this is to enable warnings
    in all the C code used by OCaml programs.

    -fno-strict-overflow is used throughout the build to avoid dubious GCC
    optimizations.

    Multiple cleanups to support GCC 5.

    OCaml OUnit2 is needed to run some OCaml tests.

    Creating a statically linked libguestfs.a should work again.

    The src/api-support subdirectory and its scripts are no longer used.
    Instead we store in the generator/actions.ml when the API was added to
    libguestfs.

 Internationalization

    The translation service has changed from Transifex to Zanata.

    Many more translations are available now, for both library and tools
    messages and documentation.

 Internals

    In all OCaml tools, there are now common error, warning, info
    functions, and common way to set and get the --quiet, -x (trace) and -v
    (verbose) flags, and colour highlighting used consistently.

    COMPILE_REGEXP macros are used to simplify PCRE constructors and
    destructors.

    In the generator, Pointer arguments have finally been implemented.

    Internal identifiers no longer use double and triple underscores (eg.
    guestfs___program_name). These identifiers are invalid for C99 and C++
    programs, although compilers would accept them.

    The daemon no longer parses guestfs_* options from /proc/cmdline.
    Instead it only takes ordinary command line options. The appliance init
    script turns /proc/cmdline into daemon command line options.

    The tests can now run the daemon as a "captive process", allowing it to
    be run directly on the host. The main advantage of this is we can run
    valgrind directly on the daemon during testing.
