CVE-2013-6458
Generally, every API that is going to begin a job should do that before
fetching data from vm->def. However, qemuDomainGetBlockInfo does not
know whether it will have to start a job or not before checking vm->def.
To avoid using disk alias that might have been freed while we were
waiting for a job, we use its copy. In case the disk was removed in the
meantime, we will fail with "cannot find statistics for device '...'"
error message.

CVE-2013-6458
https://bugzilla.redhat.com/show_bug.cgi?id=1043069
When virDomainDetachDeviceFlags is called concurrently to
virDomainBlockStats: libvirtd may crash because qemuDomainBlockStats
finds a disk in vm->def before getting a job on a domain and uses the
disk pointer after getting the job. However, the domain in unlocked
while waiting on a job condition and thus data behind the disk pointer
may disappear. This happens when thread 1 runs
virDomainDetachDeviceFlags and enters monitor to actually remove the
disk. Then another thread starts running virDomainBlockStats, finds the
disk in vm->def, and while it's waiting on the job condition (owned by
the first thread), the first thread finishes the disk removal. When the
second thread gets the job, the memory pointed to be the disk pointer is
already gone.
That said, every API that is going to begin a job should do that before
fetching data from vm->def.

Conflicts:
src/qemu/qemu_driver.c - context: no ACLs
The function doesn't check whether the request is made for active or
inactive domain. Thus when the domain is not running it still tries
accessing non-existing cgroups (priv->cgroup, which is NULL).
I re-made the function in order for it to work the same way it's qemu
counterpart does.
Reproducer:
1) Define an LXC domain
2) Do 'virsh memtune <domain> --hard-limit 133T'

Since 76b644c when the support for RAM filesystems was introduced,
libvirt accepted the following XML:
<source usage='1024' unit='KiB'/>
This was parsed correctly and internally stored in bytes, but it
was formatted as (with an extra 's'):
<source usage='1024' units='KiB'/>
When read again, this was treated as if the units were missing,
meaning libvirt was unable to parse its own XML correctly.
The usage attribute was documented as being in KiB, but it was not
scaled if the unit was missing. Transient domains still worked,
because this was balanced by an extra 'k' in the mount options.
This patch:
Changes the parser to use 'units' instead of 'unit', as the latter
was never documented (fixing persistent domains) and some programs
(libvirt-glib, libvirt-sandbox) already parse the 'units' attribute.
Removes the extra 'k' from the tmpfs mount options, which is needed
because now we parse our own XML correctly.
Changes the default input unit to KiB to match documentation, fixing:

The virBitmapParse function was calling virBitmapIsSet() function that
requires the caller to check the bounds of the bitmap without checking
them. This resulted into crashes when parsing a bitmap string that was
exceeding the bounds used as argument.
This patch refactors the function to use virBitmapSetBit without
checking if the bit is set (this function does the checks internally)
and then counts the bits in the bitmap afterwards (instead of keeping
track while parsing the string).
This patch also changes the "parse_error" label to a more common
"error".
The refactor should also get rid of the need to call sa_assert on the
returned variable as the callpath should allow coverity to infer the
possible return values.

With unknown good reasons, the attribute "bus" of scsi device
address is always set to 0, same for attribute "target". (See
virDomainDiskDefAssignAddress).
Though we might need to change the algorithm to honor "bus"
and "target" too, that's a different issue. The address generator
for scsi host device in this patch just follows the unknown
good reasons, only considering the "controller" and "unit".
It walks through all scsi controllers and their units, to see
if the address $controller:0:0:$unit can be used (if not used
by any disk or scsi host device yet), if found one, it sits on
it, otherwise, it creates a new controller (actually the controller
is implicitly created by someone else), and sits on
$new_controller:0:0:0 instead.
This should resolve:

The problem was that qemuUpdateActivePciHostdevs was returning 0

error, it would not only stop reconnecting, but would terminate the
guest qemu process "to remove danger of it ending up running twice if
user tries to start it again later".

for f0::0d:5901: Servname not supported for ai_socktype
since QEMU treats everything after the first ':' as the port.

During domain destruction it's possible that the learnIPAddressThread has
already removed the interface prior to the teardown filter path being run.
The teardown code would only be telling the thread to terminate.
Commit '6afdfc8e' adjusted the exit and error paths to go through the error
and cleanup labels, but neglected to remove the return ret prior to cleanup.
Also noted the 'type' xml string fetch was never checked for NULL which
could lead to some interesting results.
If snapshot creation failed for example due to invalid use of the
"REUSE_EXTERNAL" flag, libvirt killed access to the original image file
instead of the new image file. On machines with selinux this kills the
whole VM as the selinux context is enforced immediately.
* qemu_driver.c:qemuDomainSnapshotUndoSingleDiskActive():
- Kill access to the new image file instead of the old one.

Commit d671121d was incomplete; I hit another compile fail on
cygwin not finding the correct rpc/rpc.h.

A bug in Cygwin [1] and poor error messages from gcc [2] lead
to this confusing compilation error:
qemu/qemu_monitor.c:418:9: error: passing argument 2 of 'sendmsg' from incmpatible pointer type
/usr/include/sys/socket.h:42:11: note: expected 'const struct msghdr *' but argument is of type 'struct msghdr *'

[2] http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57475
* src/qemu/qemu_monitor.c (includes): Include <sys/socket.h>
before <sys/un.h>.

This is a recurring problem for cygwin :)
For example, see commit 23a4df88.
qemu/qemu_driver.c: In function 'qemuStateInitialize':
qemu/qemu_driver.c:691:13: error: format '%d' expects type 'int', but argument 8 has type 'uid_t' [-Wformat]
* src/qemu/qemu_driver.c (qemuStateInitialize): Add casts.
* daemon/remote.c (remoteDispatchAuthList): Likewise.

A cygwin build of the qemu driver fails with:
qemu/qemu_process.c: In function 'qemuPrepareCpumap':
qemu/qemu_process.c:1803:31: error: 'CPU_SETSIZE' undeclared (first use in this function)
CPU_SETSIZE is a Linux extension in <sched.h>; a bit more portable
is using sysconf if _SC_NPROCESSORS_CONF is defined (several platforms
have it, including Cygwin). Ultimately, I would have preferred to
use gnulib's 'nproc' module, but it is currently under an incompatible
license.
* src/qemu/qemu_conf.h (QEMUD_CPUMASK_LEN): Provide definition on
cygwin.

On cygwin, the build failed with:

Compilation on cygwin failed due to a bug in the sasl headers
present on that platform (libsasl2-devel 2.1.26):
In file included from rpc/virnetserverclient.c:27:0:
/usr/include/sasl/sasl.h:230:38: error: expected declaration specifiers or '...' before 'size_t'
Upstream is aware of their bug:
https://bugzilla.cyrusimap.org/show_bug.cgi?id=3759
* src/rpc/virnetserverclient.c (includes): Ensure size_t is
defined before using sasl.h.

Bummer, I committed, then fixed a typo, then tested, and forgot to
amend the commit before pushing 7d21d6b6.
* src/rpc/virnettlscontext.c (includes): Use correct spelling.
