Our option '--with-test-suite' could have never worked since it was
defined as AC_ARG_ENABLE([with-test-suite], ...), thus working only as
'--enable-with-test-suite', but documented in configure.ac as
AC_HELP_STRING([--with-test-suite], ...).
In my opinion, the help string is as it should be, but the option is
wrong.

As the python generator scripts are written in python2,
the ./configure script must check for python2 before checking for python
otherwise, on platforms where both python2 and python3 are available and
on which the default python points to python3, ./configure will try to use

This patch resolves a compile issue caused by the
removal of examples/domsuspend code in commit
5eb4b042. This issue
is only seen in a fresh checkout, but causes the build
and configure to fail.

* po/*.po*: update and merge localizations from transifex

When looking for numad with AC_PATH_PROG, include /usr/sbin in
the search path.

We support gluster volumes in domain XML, so we also ought to
support them as a storage pool.  Besides, a future patch will
want to take advantage of libgfapi to handle the case of a
gluster device holding qcow2 rather than raw storage, and for
that to work, we need a storage backend that can read gluster
storage volume contents.  This sets up the framework.

Note that the new pool is named 'gluster' to match a
<disk type='network'><source protocol='gluster'> image source
already supported in a <domain>; it does NOT match the
<pool type='netfs'><source><target type='glusterfs'>,
since that uses a FUSE mount to a local file name rather than
a network name.

This and subsequent patches have been tested against glusterfs
3.4.1 (available on Fedora 19); there are likely bugs in older
versions that may prevent decent use of gfapi, so this patch
enforces the minimum version tested.  A future patch may lower
the minimum.  On the other hand, I hit at least two bugs in
3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth
raising the minimum: glfs_readdir is nicer to use than
glfs_readdir_r [1], and glfs_fini should only return failure on
an actual failure [2].

The QEMU backend was disabled on Mac OS X without a reason in the code
and due to refactors its difficult to understand when/why it was
disabled. With QEMU being supported on Mac OS X there is no reason to
disable QEMU on this platform.

The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.

The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.

Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

The automake manual recommends against the use of disabling
maintainer mode by default:

https://www.gnu.org/software/automake/manual/automake.html#maintainer_002dmode

because when it is disabled, the user gets no indication if they
touch a file that would normally require a rebuild.  Automake
1.11 changed things so that AM_MAINTAINER_MODE([enable]) will set
the mode to enabled by default; but RHEL 5 still uses automake 1.9,
where AM_MAINTAINER_MODE did not recognize an argument, and
therefore disables maintainer mode by default.  Having the default
be different according to which version of automake built the
project is annoying, and I _have_ been bitten on RHEL 5 rebuilds
where the default disabled mode led to silently incorrect builds.

The automake manual admits that being able to disable maintainer
mode still makes sense for projects that still store generated
files from the autotools in version control; but we have dropped
that for several years now.  As such, it's finally time to just
ditch the whole idea of maintainer mode, and unconditionally
rebuild autotools files if a dependency changes, without offering
a configure option to disable that mode.

* configure.ac (AM_MAINTAINER_MODE): Drop.

I tried to test ./configure --without-lxc --without-remote.
First, the build failed with some odd errors, such as an
inability to build xen, or link failures for virNetTLSInit.
But when you think about it, once there is no remote code,
all of libvirtd is useless, any stateful driver that depends
on libvirtd is also not worth compiling, and any libraries
used only by RPC code are not needed.  So I patched
configure.ac to make for some saner defaults when an
explicit disable is attempted.  Similarly, since we have
migrated virnetdevbridge into generic code, the workaround
for Linux kernel stupidity must not depend on stateful
drivers being in use.

Then there's 'make check' that needs segregation.

Wow - quite a bit of cleanup to make --without-remote useful :)

drivers and other libraries.  Pick up Linux kernel workarounds
even when qemu and lxc are not being compiled.

Fixed the safezero call for allocating the rest of the file after cloning
an existing volume; it used to always use a zero offset, causing it to
only allocate the beginning of the file.

Also modified file creation to try to use fallocate(2) to pre-allocate
disk space before copying any data to make sure it fails early on if disk
is full and makes sure we can skip zero blocks when copying file contents.

If fallocate isn't available we will zero out the rest of the file after
cloning and only use sparse cloning if client requested a lower allocation
than the input volume's capacity.

With the existing pkcheck (pid, start time) tuple for identifying
the process, there is a race condition, where a process can make
a libvirt RPC call and in another thread exec a setuid application,
causing it to change to effective UID 0. This in turn causes polkit
to do its permission check based on the wrong UID.

To address this, libvirt must get the UID the caller had at time
of connect() (from SO_PEERCRED) and pass a (pid, start time, uid)
triple to the pkcheck program.

This fix requires that libvirt is re-built against a version of
polkit that has the fix for its CVE-2013-4288, so that libvirt
can see 'pkg-config --variable pkcheck_supports_uid polkit-gobject-1'

Commits 9298bfbc and f6c29515 both tried to make it possible to
select the correct libnl (1 vs. 3) according to what netcf
used, when both libraries are installed.  This works to avoid
libnl-3 when netcf used libnl-1.  But on the converse side, if
only libnl-1 development code is installed, while netcf uses
libnl-3, then configure happily uses libnl-1 anyways, leading
to a test failure:

$ VIR_TEST_DEBUG=1 ./virdrivermoduletest
TEST: virdrivermoduletest
 1) Test driver "network"                                             ... OK

It's much nicer to prevent this at configure time, by requiring that
if we know what netcf used, then we want the same libnl version.  As
before, this can be bypassed by someone who knows what they are doing
by setting LIBNL_CFLAGS (perhaps useful to the rare person where the
build box has a different version of netcf than the installation box).

occurs before AC_ARG_WITH has had a chance to set either
$with_qemu or $with_yajl.

Coincidentally, this fix aligns with a documentation patch that

The gnulib testsuite is relatively stable - the only times it is
likely to have a test change from pass to fail is on a gnulib
submodule update or a major system change (such as moving from
Fedora 18 to 19, or other large change to libc).  While it is an
important test for end users on arbitrary machines (to make sure
that the portability glue works for their machine), it mostly
wastes time for development testing (as most developers aren't
making any of the major changes that would cause gnulib tests
to alter behavior).  Thus, it pays to make the tests optional
at configure time, defaulting to off for development, on for
tarballs, with autobuilders requesting it to be on.  It also
helps to allow a make-time override, via VIR_TEST_EXPENSIVE=[01]
(much the way automake sets up V=[01] for overriding the configure
time default of how verbose to be).

Automake has some pretty hard-coded magic with regards to the
TESTS variable; I had quite a job figuring out how to keep
'make distcheck' passing regardless of the configure option
setting in use, while still disabling the tests at runtime
when I did not configure them on and did not use the override
variable.  Thankfully, we require GNU make, which lets me

Newer gnutls uses nettle, rather than gcrypt, which is a lot nicer
regarding initialization.  Yet we were unconditionally initializing
gcrypt even when gnutls wouldn't be using it, and having two crypto
libraries linked into libvirt.so is pointless, but mostly harmless
(it doesn't crash, but does interfere with certification efforts).

There are three distinct version ranges to worry about when
determining which crypto lib gnutls uses, per these gnutls mails:

3.0: http://lists.gnu.org/archive/html/gnutls-devel/2011-07/msg00035.html
