0fc12bca08 tests: Introduce qemuhotplugtest
As my punishment for the break in 7f15ebc7 (fixed in 752596b5dd) I'm
introducing this test to make sure it won't happen again. Currently,
only test for <graphics/> is supported.

686026225e Auto-generate helpers for checking access control rules
Extend the 'gendispatch.pl' script to be able to generate
three new types of file.

- 'aclheader' - defines signatures of helper APIs for
  doing authorization checks. There is one helper API
  for each API requiring an auth check. Any @acl
  annotations result in a method being generated with
  a suffix of 'EnsureACL'. If the ACL check requires
  examination of flags, an extra 'flags' param will be
  present. Some examples

  extern int virConnectBaselineCPUEnsureACL(void);
  extern int virConnectDomainEventDeregisterEnsureACL(virDomainDefPtr domain);
  extern int virDomainAttachDeviceFlagsEnsureACL(virDomainDefPtr domain, unsigned int flags);

  Any @aclfilter annotations resuilt in a method being
  generated with a suffix of 'CheckACL'.

  extern int virConnectListAllDomainsCheckACL(virDomainDefPtr domain);

  These are used for filtering individual objects from APIs
  which return a list of objects

- 'aclbody' - defines the actual implementation of the
  methods described above. This calls into the access
  manager APIs. A complex example:

    /* Returns: -1 on error (denied==error), 0 on allowed */
    int virDomainAttachDeviceFlagsEnsureACL(virConnectPtr conn,
                                            virDomainDefPtr domain,
                                            unsigned int flags)
    {
        virAccessManagerPtr mgr;
        int rv;

        if (!(mgr = virAccessManagerGetDefault()))
            return -1;

        if ((rv = virAccessManagerCheckDomain(mgr,
                                              conn->driver->name,
                                              domain,
                                              VIR_ACCESS_PERM_DOMAIN_WRITE)) <= 0) {
            virObjectUnref(mgr);
            if (rv == 0)
                virReportError(VIR_ERR_ACCESS_DENIED, NULL);
            return -1;
        }
        if (((flags & (VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE)) == 0) &&
            (rv = virAccessManagerCheckDomain(mgr,
                                              conn->driver->name,

            if (rv == 0)
                virReportError(VIR_ERR_ACCESS_DENIED, NULL);
            return -1;
        }
        if (((flags & (VIR_DOMAIN_AFFECT_CONFIG)) == (VIR_DOMAIN_AFFECT_CONFIG)) &&
            (rv = virAccessManagerCheckDomain(mgr,
                                              conn->driver->name,
                                              domain,
                                              VIR_ACCESS_PERM_DOMAIN_SAVE)) <= 0) {
            virObjectUnref(mgr);
            if (rv == 0)
                virReportError(VIR_ERR_ACCESS_DENIED, NULL);
            return -1;
        }
        virObjectUnref(mgr);
        return 0;
    }

   APIs to drivers. Some examples

b904bba7f4 Add a policy kit access control driver
Add an access control driver that uses the pkcheck command
to check authorization requests. This is fairly inefficient,
particularly for cases where an API returns a list of objects
and needs to check permission for each object.

It would be desirable to use the polkit API but this links
to glib with abort-on-OOM behaviour, so can't be used. The
other alternative is to speak to dbus directly

d14524701a Add a test suite for cgroups functionality
Some aspects of the cgroups setup / detection code are quite subtle
and easy to break. It would greatly benefit from unit testing, but
this is difficult because the test suite won't have privileges to
play around with cgroups. The solution is to use monkey patching
via LD_PRELOAD to override the fopen, open, mkdir, access functions
to redirect access of cgroups files to some magic stubs in the
test suite.

Using this we provide custom content for the /proc/cgroup and
/proc/self/mounts files which report a fixed cgroup setup. We
then override open/mkdir/access so that access to the cgroups
filesystem gets redirected into files in a temporary directory
tree in the test suite build dir.

3d1596b048 Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.

The actual APIs are

  int virDomainLxcOpenNamespace(virDomainPtr domain,
                                int **fdlist,
                                unsigned int flags);

  int virDomainLxcEnterNamespace(virDomainPtr domain,
                                 unsigned int nfdlist,
                                 int *fdlist,
                                 unsigned int *noldfdlist,
                                 int **oldfdlist,
                                 unsigned int flags);

which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.

NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

There are many aspects of the guest XML which result in the
SELinux driver applying file labelling. With the increasing
configuration options it is desirable to test this behaviour.
It is not possible to assume that the test suite has the
ability to set SELinux labels. Most filesystems though will
support extended attributes. Thus for the purpose of testing,
it is possible to extend the existing LD_PRELOAD hack to

 - Ensure locks can be preserved across libvirtd restarts.

eca72d4759 Introduce an internal API for handling file based lockspaces
The previously introduced virFile{Lock,Unlock} APIs provide a
way to acquire/release fcntl() locks on individual files. For
unknown reason though, the POSIX spec says that fcntl() locks
are released when *any* file handle referring to the same path
is closed. In the following sequence

  threadA: fd1 = open("foo")
  threadB: fd2 = open("foo")
  threadA: virFileLock(fd1)
  threadB: virFileLock(fd2)
  threadB: close(fd2)

you'd expect threadA to come out holding a lock on 'foo', and
indeed it does hold a lock for a very short time. Unfortunately
when threadB does close(fd2) this releases the lock associated
with fd1. For the current libvirt use case for virFileLock -
pidfiles - this doesn't matter since the lock is acquired
at startup while single threaded an never released until
exit.

To provide a more generally useful API though, it is necessary
to introduce a slightly higher level abstraction, which is to
be referred to as a "lockspace".  This is to be provided by
a virLockSpacePtr object in src/util/virlockspace.{c,h}. The
core idea is that the lockspace keeps track of what files are
already open+locked. This means that when a 2nd thread comes
along and tries to acquire a lock, it doesn't end up opening
and closing a new FD. The lockspace just checks the current
list of held locks and immediately returns VIR_ERR_RESOURCE_BUSY.

NB, the API as it stands is designed on the basis that the
files being locked are not being otherwise opened and used
by the application code. One approach to using this API is to
acquire locks based on a hash of the filepath.

eg to lock /var/lib/libvirt/images/foo.img the application
might do

   virLockSpacePtr lockspace = virLockSpaceNew("/var/lib/libvirt/imagelocks");
   lockname = md5sum("/var/lib/libvirt/images/foo.img");
   virLockSpaceAcquireLock(lockspace, lockname);

NB, in this example, the caller should ensure that the path
is canonicalized before calculating the checksum.

It is also possible to do locks directly on resources by
using a NULL lockspace directory and then using the file
path as the lock name eg

   virLockSpacePtr lockspace = virLockSpaceNew(NULL);
   virLockSpaceAcquireLock(lockspace, "/var/lib/libvirt/images/foo.img");

This is only safe to do though if no other part of the process
will be opening the files. This will be the case when this
code is used inside the soon-to-be-reposted virlockd daemon

If you are already in the tools/ subdirectory, then the following
command will also work:

  ../run ./virsh [...]

You can also run the C programs under valgrind like this:

  ./run valgrind [valgrind opts...] ./program

or under gdb:

  ./run gdb --args ./program

This also works with sudo (eg. if you need root access for libvirt):

  sudo ./run ./tools/virsh list --all

Derived from libguestfs and simplified.  The ./run script in
libguestfs is much more sophisticated:

0c9fd4cfe9 Rewrite virAtomic APIs using GLib's atomic ops code
There are a few issues with the current virAtomic APIs

 - They require use of a virAtomicInt struct instead of a plain
   int type
 - Several of the methods do not implement memory barriers
 - The methods do not implement compiler re-ordering barriers
 - There is no Win32 native impl

The GLib library has a nice LGPLv2+ licensed impl of atomic
ops that works with GCC, Win32, or pthreads.h that addresses
all these problems. The main downside to their code is that
the pthreads impl uses a single global mutex, instead of
a per-variable mutex. Given that it does have a Win32 impl
though, we don't expect anyone to seriously use the pthread.h
impl, so this downside is not significant.

* .gitignore: Ignore test case
* configure.ac: Check for which atomic ops impl to use
* src/Makefile.am: Add viratomic.c
* src/nwfilter/nwfilter_dhcpsnoop.c: Switch to new atomic
  ops APIs and plain int datatype
* src/util/viratomic.h: inline impls of all atomic ops
  for GCC, Win32 and pthreads
* src/util/viratomic.c: Global pthreads mutex for atomic
  ops
* tests/viratomictest.c: Test validate to validate safety
  of atomic ops.

9117fcb263 Run an RPC protocol over the LXC controller monitor
This defines a new RPC protocol to be used between the LXC
controller and the libvirtd LXC driver. There is only a
single RPC message defined thus far, an asynchronous "EXIT"
event that is emitted just before the LXC controller process
exits. This provides the LXC driver with details about how
the container shutdown - normally, or abnormally (crashed),
thus allowing the driver to emit better libvirt events.

Emitting the event in the LXC controller requires a few
little tricks with the RPC service. Simply calling the
virNetServiceClientSendMessage does not work, since this
merely queues the message for asynchronous processing.
In addition the main event loop is no longer running at
the point the event is emitted, so no I/O is processed.

Thus after invoking virNetServiceClientSendMessage it is
necessary to mark the client as being in "delayed close"
mode. Then the event loop is run again, until the client
completes its close - this happens only after the queued
message has been fully transmitted. The final complexity
is that it is not safe to run virNetServerQuit() from the
client close callback, since that is invoked from a
context where the server is locked. Thus a zero-second
timer is used to trigger shutdown of the event loop,
causing the controller to finally exit.

* src/Makefile.am: Add rules for generating RPC protocol
  files and dispatch methods
* src/lxc/lxc_controller.c: Emit an RPC event immediately
  before exiting
* src/lxc/lxc_domain.h: Record the shutdown reason
  given by the controller
* src/lxc/lxc_monitor.c, src/lxc/lxc_monitor.h: Register
  RPC program and event handler. Add callback to let
  driver receive EXIT event.
* src/lxc/lxc_process.c: Use monitor exit event to decide
  what kind of domain event to emit
* src/lxc/lxc_protocol.x: Define wire protocol for LXC
  controller monitor.

1bfb47dfe6 Make ESX & Hyper-V code generator safe with parallel builds
If from a clean GIT checkout 'make -j 8' is run, the ESX
and Hyper-V code will be generated multiple times over.
This is because there are multiple files being generated
from one invocation of the generator script. make does not
realize this and so invokes the generator once per file.
This doesn't matter with serialized builds, but with
parallel builds multiple instances of the generator get
run at once.

29bc4fe646 Add a sheepdog backend for the storage driver
This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.

A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.

A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.

In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.

  <disk type='network'>
    ...
    <source protocol="sheepdog" name="vdi_name">
      <host name="localhost" port="7000"/>
    </source>
  </disk>

To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

6a714d31d0 Switch automated builds to use Mingw64 toolchain instead of Mingw32
The Mingw32 toolchain is broadly obsoleted by the Mingw64 toolchain.
The latter has been adopted by Fedora 17 and newer. Maintaining a
RPM spec for Mingw32 is a needless burden, so switch to a Mingw64
RPM spec (which provides 32 & 64 bit builds).

fb59cf7a58 build: fix testing of augeas files in VPATH builds
Without this fix, a VPATH build (such as used by ./autobuild.sh)
fails with messages like:

make[3]: Entering directory `/home/remote/eblake/libvirt-tmp2/build/daemon'
../../build-aux/augeas-gentest.pl libvirtd.conf ../../daemon/test_libvirtd.aug.in test_libvirtd.aug
cannot read libvirtd.conf: No such file or directory at ../../build-aux/augeas-gentest.pl line 38.

Since the test files are not part of the tarball, we can generate
them into the build dir, but rather than create a subdirectory
just for the test file, it is easier to test them directly in
libvirt.git/src.

* daemon/Makefile.am (AUG_GENTEST): Factor out definition.
(test_libvirtd.aug): Look for correct file.
* src/Makefile.am (AUG_GENTEST): Use $(PERL).
(qemu/test_libvirtd_qemu.aug, lxc/test_libvirtd_lxc.aug)
(locking/test_libvirt_sanlock.aug): Rename to avoid subdirectories.
(check-augeas-qemu, check-augeas-lxc, check-augeas-sanlock): Reflect
location of built tests.
* configure.ac (PERL): Substitute perl.

de9758ae9b Autogenerate augeas test case from default config files
When adding new config file parameters, the corresponding
additions to the augeas lens' are constantly forgotten.
Also there are augeas test cases, these don't catch the
error, since they too are never updated.

To address this, the augeas test cases need to be auto-generated
from the example config files.

  augeas test file, substituting in elements from the
  example config files
