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'

Commit f92c7e3 fixed a regression for native builds, but introduced
a regression for cross-compilation builds; in particular,
./autobuild.sh on a Fedora system with mingw cross-compiler fails
with:
checking for qemu-kvm... /usr/bin/qemu-kvm
checking for yajl_parse_complete in -lyajl... no
checking for yajl_tree_parse in -lyajl... no
configure: error: You must install the libyajl library & headers to compile libvirt
Since we default $with_qemu to 'yes' rather than 'check', and then
flip that default based on platform-specific checks, those platform
specifics need to come prior to any library checks that depend on
the value of $with_qemu.

Commits 9298bfb and f6c2951 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
2) Test driver "storage" ... OK
3) Test driver "nodedev" ... OK

5) Test driver "nwfilter" ... OK
6) Test driver "interface"
... lt-virdrivermoduletest: route/tc.c:973: rtnl_tc_register: Assertion
`0' failed.
Aborted
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).
* configure.ac (LIBNL): If we can prove netcf used libnl-3, then
don't let configure succeed with libnl-1.

Jonathan Lebon reported an issue to me off-list about his build
failing to use qemu because he failed to install yajl-devel. But
I recalled specifically tweaking configure.ac to die in that
situation (commits 350583c, ba9c38b). After a bit more
head-scratching, we found the cause of the regression: commit
654c709 rearranged things so that the qemu version check now
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
was just posted to the autoconf mailing list :)

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
hide some information from Automake's magic handling of TESTS.

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:
2.12: http://lists.gnu.org/archive/html/gnutls-devel/2011-03/msg00034.html
3.0: http://lists.gnu.org/archive/html/gnutls-devel/2011-07/msg00035.html
If pkg-config can prove version numbers and/or list the crypto
library used for static linking, we have our proof; if not, it
is safer (even if pointless) to continue to use gcrypt ourselves.

The python/tests directory contains a number of so called

look for Xen and cannot be run in any automated fashion,

them.
For some reason these tests were also copied into the

link_addr detection in configure always reports that
link_addr is missing because it uses link_addr(NULL, NULL) in
AC_LINK_IFELSE check with limited set of headers that doesn't
define NULL.
Fix by replacing 'NULL' with just '0'.
Some versions of kFreeBSD (like 9.0) declare link_addr in a header
but lack an implementation. This makes ./configure pass but breaks
compilation later with a
undefined reference to `link_addr'
Althought that's a bug in the OS header we can detect it easily by also
trying to link.

This patch adds two sets of functions:
1) lower level virProcessSet*() functions that will immediately set
the RLIMIT_MEMLOCK. RLIMIT_NPROC, or RLIMIT_NOFILE of either the
current process (using setrlimit()) or any other process (using
prlimit()). "current process" is indicated by passing a 0 for pid.
2) functions for virCommand* that will setup a virCommand object to
set those limits at a later time just after it has forked a new
process, but before it execs the new program.
configure.ac has prlimit and setrlimit added to the list of functions
to check for, and the low level functions log an "unsupported" error)
on platforms that don't support those functions.
Add a virCgroupIsolateMount method which looks at where the
current process is place in the cgroups (eg /system/demo.lxc.libvirt)
and then remounts the cgroups such that this sub-directory
becomes the root directory from the current process' POV.

Every source file is currently built twice by libtool, once for
the shared library and once for the static library. Static libs
are not commonly packaged by distros and slow down compilation
time by more than 50% compared to a shared-only build time.
Time for 'make -j 4':
shared only: 2 mins 9 secs
shared + static: 3 mins 26 secs
Time for non-parallel make
shared only: 3 mins 32 secs
shared + static: 5 mins 41 secs
Those few people who really want them, can pass --enable-static
to configure
Disabling them by default requires use of LT_INIT, but for
compat with RHEL5 we can't rely on that. So we conditionally
use LT_INIT, but fallback to AM_PROG_LIBTOOL if not present.
