2b510e4903 Fix off-by-1 in default SELinux MCS range
For a while we're have random failures of 'securityselinuxtest'
which were not at all reproducible. Fortunately we finally
caught a failure with VIR_TEST_DEBUG=1 enabled. This revealed

TEST: securityselinuxtest
 1) GenLabel "dynamic unconfined, s0, c0.c1023"                       ... OK

 7) GenLabel "dynamic virtd, missing range"                           ... Category two 1024 is out of range 0-1023
FAILED
FAIL: securityselinuxtest

And sure enough we had an off-by-1 in the MCS range code when
the current process has no range set. The test suite randomly
allocates 2 categories from 0->1024 so the chances of hitting
this in the test suite were slim indeed :-)

caaeb691a3 spec: fix libvirt-docs subpackage on RHEL-6
RHEL-6's rpmbuild wipes the docdir for a (sub-)package if any %doc
directives are present, prior to copying in the marked documentation.
This means we can't prepopulate this directory with the HTML
documentation during the %install phase.

Instead, move the HTML documentation to a temporary directory during
%install and mark the contents of this temporary directory with %doc.

This fixes a build regression introduced in

9eb23fe24e build: work around super-old readline.h
This patch shuts up the following warning of clang
on Mac OS X:

  virsh.c:2761:22: error: assigning to 'char *' from 'const char [6]' discards qualifiers
      [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
      rl_readline_name = "virsh";
                       ^ ~~~~~~~

The warning happens because rl_readline_name on Mac OS X comes
from an old readline header that still uses 'char *', while it
is 'const char *' in readline 4.2 (April 2001) and newer.

Tested on Mac OS X 10.8.5 (clang-500.2.75) and Fedora 19 (gcc 4.8.1).

3563c51d3e Avoid async signal safety problem in glibc's setxid
The glibc setxid is supposed to be async signal safe, but
libc developers confirm that it is not. This causes a problem
when libvirt_lxc starts the FUSE thread and then runs clone()
to start the container. If the clone() was done before the
FUSE thread has completely started up, then the container
will hang in setxid after clone().

The fix is to avoid creating any threads until after the
container has been clone()'d. By avoiding any threads in
the parent, the child is no longer required to run in an
async signal safe context, and we thus avoid the glibc
bug.

8c41794af8 Return -1 in virPortAllocatorAcquire if all ports are used
Report the error in virPortAllocatorAcquire instead
of doing it in every caller.

The error contains the port range name instead of the intended
use for the port, e.g.:
Unable to find an unused port in range 'display' (65534-65535)
instead of:
Unable to find an unused port for SPICE

This also adds error reporting when the QEMU driver could not
find an unused port for VNC, VNC WebSockets or NBD migration.

05e149f94c qemu: Call qemuSetupHostdevCGroup later during hotplug
https://bugzilla.redhat.com/show_bug.cgi?id=1025108

So far qemuSetupHostdevCGroup was called very early during hotplug, even
before we knew the device we were about to hotplug was actually
available. By calling the function later, we make sure QEMU won't be
allowed to access devices used by other domains.

Another important effect of this change is that hopluging USB devices
specified by vendor and product (but not by their USB address) works
again. This was broken since v1.0.5-171-g7d763ac, when the call to
qemuFindHostdevUSBDevice was moved after the call to
qemuSetupHostdevCGroup, which then used an uninitialized USB address.

f417ad07df qemuMonitorIO: Don't use @mon after it's unrefed
https://bugzilla.redhat.com/show_bug.cgi?id=1018267

The aim of virObject refing and urefing is to tell where the object is
to be used and when is no longer needed. Hence any object shouldn't be
used after it has been unrefed, as we might be the last to hold the
reference. The better way is to call virObjectUnref() *after* the last
object usage. In this specific case, the monitor EOF handler was called
after the qemuMonitorIO called virObjectUnref. Not only that @mon was
disposed (which is not used in the handler anyway) but the @mon->vm
which is causing a SIGSEGV:

3367c21dad qemuProcessReconnectHelper: Don't create joinable thread
In the qemuProcessReconnectHelper() a new thread that does all the
interesting work is spawned. The rationale is to not block the daemon
startup process in case of unresponsive qemu. However, the thread
handler is a local variable which gets lost once the control goes out of
scope. Hence the thread gets leaked. We can avoid this if the thread
isn't made joinable.

887dd3625b storage: fix RNG validation of gluster via netfs
While trying to compare netfs against my new gluster pool, I
discovered two things:

virt-xml-validate chokes on valid xml produced by 'virsh pool-dumpxml'
[yet another reason that ALL patches that add new xml should be adding
corresponding tests]

When using glusterfs FUSE mounts, you cannot access a subdirectory
of a gluster volume.  The recommended workaround in the gluster
community is to mount the volume to an intermediate location, then
bind-mount the desired subdirectory to the final location.  Maybe
we should teach libvirt to do bind-mounting, but for now I chose to
just document the limitation.

84f6960214 qemu: Check for presence of device and properities when getting CPUID
The QOM path in qemu that contains the CPUID registers of a running VM
may not be present (introduced in QEMU 1.5).

Since commit d94b781771 we have a regression with QEMU that don't
support reporting of the CPUID register state via the monitor as the
process startup code expects the path to exist.

This patch adds code that checks with the monitor if the requested path
already exists and uses it only in this case.

48072521b6 virsh-volume: Unify strigification of volume type
There were two separate places with that were stringifying type of a
volume. One of the places was out of sync with types implemented
upstream.

To avoid such problems in the future, this patch adds a common function
to convert the type to string and reuses it across the two said places.

7f2b173feb Improve cgroups docs to cover systemd integration
As of libvirt 1.1.1 and systemd 205, the cgroups layout used by
libvirt has some changes. Update the 'cgroups.html' file from
the website to describe how it works in a systemd world.

5087a5a009 Fix busy wait loop in LXC container I/O handling
If the host side of an LXC container console disconnected
and the guest side continued to write data, until the PTY
buffer filled up, the LXC controller would busy wait. It
would repeatedly see POLLHUP from poll() and not disable
the watch.

This was due to some bogus logic detecting blocking
conditions. Upon seeing a POLLHUP we must disable all
reading & writing from the PTY, and setup the epoll to
wake us up again when the connection comes back.

cbb6ec42e2 Don't expose 'none' machine type to capabilities
The 'none' machine type is something only intended for use
by libvirt probing capabilities. It isn't something that
is useful for running real VM instances. As such it should
not be exposed to users in the capabilities.

f41830680e Fix mem leak in virQEMUCapsProbeQMPMachineTypes on OOM
The virQEMUCapsProbeQMPMachineTypes method iterates over machine
types copying them into the qemuCapsPtr object. It only updates
the qemuCaps->nmachinetypes value at the end though. So if OOM
occurs in the middle, the destructor of qemuCapsPtr will not
free the partially initialized machine types.

16bc786408 conf: Split out code to parse the source of a disk definition
To avoid code duplication between snapshot configuration code that
parses the disk source too we need to split out this code that will be
reused later on.

This patch tries to be code movement, some aspects of this function will
be refactored later.

cfc28c66f9 qemuDomainObjStart: Warn on corrupted image
If the managedsave image is corrupted, e.g. the XML part is, we fail to
parse it and throw an error, e.g.:

error: Failed to start domain jms8
error: XML error: missing security model when using multiple labels

This is okay, as we can't really start the machine and avoid undefined
qemu behaviour. On the other hand, the error message doesn't give a
clue to users what should they do. The consensus here would be to thrown
a warning to logs saying "Hey, you've got a corrupted file".
