[PATCH] daemon: fix directory outside current root when executing commands
by Matthew Booth
When executing a command, we temporarily chroot, fork and exec the command, then
chroot back. We intentionally don't chdir in the parent process so that we can
'jailbreak' the chroot later. However, this has the effect that commands are
executed with a current working directory which is outside the current root.
This unusual state can cause errors in executed commands which don't anticipate
it.
This change does a chdir("/") before executing and command. This happens inside
the fork, so the jailbreak isn't affected in the parent.

ANNOUNCE: libguestfs 1.20 - tools for accessing and modifying virtual machine disk images
by Richard W.M. Jones
I'm very pleased to announce the release of libguestfs 1.20.
Libguestfs is a library and a comprehensive set of tools for accessing
and modifying virtual machine (VM) disk images. For more information
see http://libguestfs.org
Libguestfs 1.20 represents 7 months of upstream work, dozens of major new
features and bug fixes. For full details read the release notes below.
You can download the libguestfs source from
http://libguestfs.org/download/1.20-stable
and packages will soon be available for Fedora 18 and Debian Wheezy.
For additional notes on Fedora 18, see:
https://www.redhat.com/archives/libguestfs/2012-December/msg00047.html
For additional notes on Debian Wheezy, see:
https://www.redhat.com/archives/libguestfs/2012-December/msg00046.html
----------------------------------------
You can also read the release notes online at:
http://libguestfs.org/guestfs-release-notes.1.html
RELEASE NOTES FOR LIBGUESTFS 1.20
New features
libvirt and sVirt (SELinux confinement)
You can optionally use libvirt to launch and manage the backend
appliance by:
* setting LIBGUESTFS_ATTACH_METHOD=libvirt[:URI]
* using ./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.
language bindings
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.
Fedora 18 is now supported.
Inspection of ISOs/CDs/DVDs can now use the libosinfo database.
ports
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.
daemon
A man page for the daemon (guestfsd(8)) is included.
Security
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.
This issue was assigned CVE-2012-2690, and is fixed in libguestfs ≥
1.16.

Internals
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).
New configure options ./configure --enable-code-profiling and
./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).

Release notes appendix for libguestfs 1.20 on Debian Wheezy
by Richard W.M. Jones
I'm just about to release libguestfs 1.20. I want to cover some
things that are different or won't work as well in Debian Wheezy.
** Most important ** Debian Wheezy ships with febootstrap 3.17. This
is too old to run libguestfs 1.20 out of the box (febootstrap >= 3.20
required). However if you apply the attached patch to libguestfs,
then it will work with the older febootstrap.
virtio-scsi is not working properly in the older version of qemu that
Debian Wheezy ships (qemu 1.1 is shipped, qemu >= 1.2 is required).
For this reason I have added code to libguestfs which detects if you
have qemu < 1.2 and forces virtio-blk. Unfortunately this means you
don't get the benefits of virtio-scsi (see the main release notes).
Because of lack of virtio-scsi and too old libvirt (libvirt 0.9.12 is
shipped, libvirt >= 0.10.2 is required), the new libvirt attach-method
will not work in Debian. See the release notes for what you'll miss
out on. Of course the default (appliance) method works fine, and
libvirt is not required.
Even if newer libvirt and qemu where available in Debian, it seems
unlikely that sVirt protection would work. This is partly because of
the obvious fact that Debian doesn't use SELinux (by default). But
mainly because we have made several changes to the SELinux policy in
Fedora to support libguestfs with libvirt and sVirt. Also, although
in theory AppArmor could implement sVirt (there is code in libvirt to
do this) I have not even come close to testing this scenario.
The tune2fs test is broken (in libguestfs). The easiest thing is just
to skip it:
export SKIP_TEST_TUNE2FS=1
'vfat' filesystem on Debian is somehow different from the same kernel
filesystem on Fedora. I don't exactly know why but this breaks the
test-charset-fidelity test. You can skip this by doing:
export SKIP_TEST_CHARSET_FIDELITY=1
The IDE device either isn't emulated by Debian's KVM, or there is a
missing driver in the Debian kernel, or for some other reason it
doesn't work. I didn't look closely, but skipped the test by doing:
export SKIP_TEST_RHBZ690819_SH=1
Disk labels (a new feature) don't work with Debian udev. Again, I did
not investigate in depth. You can skip the test by doing:
export SKIP_TEST_DISK_LABELS_PL=1

You need to run 'libguestfs-test-tool' and paste the complete,
unedited output into your reply.
I suspect the problem may be that update-guestfs-appliance is in fact
not being run for some reason.

Remove 3 unused fields from the filesystem struct
by Matthew Booth
These 3 patches remove unused fields from the filesystem struct, and the
inspection code which populates them. The second 2 are fairly trivial NFCs, but
the first has the potential for side effects as it entirely removes a couple of
matches from the filesystem detection code. A filesystem which was previously
matched as X and ignored might conceivably now be matched as Y instead, whereas
previously that test would never have happened. This may be a good thing or a
bad thing...

[PATCH] Add support for Windows dynamic disks (libldm / ldmtool).
by Richard W.M. Jones
This is just an initial version of the patch, not to be
applied. It implements just the diskgroup functions, ie.
corresponding to these ldmtool commands:
* ldmtool scan
* ldmtool show diskgroup <guid>
I have chosen yajl as the JSON parsing library (don't worry,
this is optional). You will also, of course, need ldmtool
which is not packaged in anything except Fedora.

[PATCH] tests: Fix qemu-wrapper.sh generation

There's some other issues with check-with-upstream-qemu, like qemu-wrapper
isn't regenerated if we specify a new QEMUDIR.
