On AArch64 the kernel prints one "processor" (lower case 'p') line per
core. As this was missing from the test data, virSysinfo was not
parsing any processors at all.
Fix the test data so the test now passes.
'make syntax-check' wants a newer gnulib for 2014 copyright.
Also, a couple of fixes for bootstrap issues reported on IRC:
- on some older glibc systems, ./configure could deadlock due to
a glibc malloc bug
- on FreeBSD systems, a broken autom4te coupled with gettext
0.18.3 prevents bootstrap; we can't work around it, but can at
least inform the user why they have a problem
And as always, portability fixes in other modules, some of which
are used by libvirt.
* .gnulib: Update to latest, in part for bootstrap improvements,
and for the new year.
* bootstrap: Resync to gnulib.

https://bugzilla.redhat.com/show_bug.cgi?id=1046337
The <driver> name attribute of an interface is interpreted in two
different ways depending on the <interface> type - if the interface is
type='hostdev', then the driver name describes which backend to use
for the hostdev device assignment (vfio or kvm), but if the interface
is any emulated type *and* the model type is "virtio", then the driver
name can be "vhost" or "qemu", telling which backend qemu should use
to communicate with the emulated device.
The problem comes when someone has defined a an interface like this
(which is accepted by the parser as long as no <driver name='xxx'/> is
specified):
<interface type='hostdev'>
...
<model type='virtio'/>
...
</interface>
As libvirt storing this definition in the domain's status, the driver
name is automatically filled in with the backend that was
automatically decided by libvirt, so it stores this in the status:
<interface type='hostdev'>
...
<driver name='vfio'/>
...
<model type='virtio'/>
...
</interface>
This isn't noticed until the next time libvirtd is restarted - as it
is reading the status of all domains, it encounters the above
interface definition, logs an error:
internal error: Unknown interface <driver name='vfio'> has been specified
and fails to reload the domain status, so the domain is marked as
inactive.
The solution is to stop the parser from interpreting <driver>
attributes as if the device was an emulated virtio device, when it is
actually a hostdev.
(Although the bug has existed since vfio support was added, it has
just recently become more apparent because libvirt previously didn't
automatically set the driver name for hostdev interfaces in the domain
status to vfio/kvm as it does since commit f094aa, first appearing in
v1.1.4.)
Similar to commit 52dbeac, we should indent code snippets in
other places to ensure they appear correctly in html. See
http://libvirt.org/html/libvirt-libvirt.html#virNodeGetCPUStats
for an example improved by this patch. Also fix some missing
semicolons in the examples.

Currently, the @flags usage is a bit unclear at first sight to say the
least. There's no need for such unclear code especially when we can
borrow the working code from qemuDomainShutdownFlags().
In addition, this fixes one bug too. If user requested both
VIR_DOMAIN_SHUTDOWN_INITCTL and VIR_DOMAIN_SHUTDOWN_SIGNAL at the same
time, he is basically saying: 'Use the force Luke! If initctl fails try
sending a signal.' But with the current code we don't do that. If
initctl fails for some reason (e.g. inability to write to /dev/initctl)
we don't try sending any signal but fail immediately. To make things
worse, making a domain shutdown with bare _SIGNAL was working by blind
chance of a @rc variable being placed at correct place on the stack so
its initial value was zero.

When registering a close callback, the connection refcount is increased
as the connection object is passed to the callback and hence we must
prevent deleting it too soon. However, when closing the connection, the
connection object is just unrefed. So whenever a connection with a close
callback is closed, we end up with the connection object which has
exactly one reference. Leaving the code as-is doesn't mean the end of
the world as we know it, but why give a bad example?

If a domain has an <interface type='hostdev'> or an <interface
type='network'> where the network itself is a pool of hostdev devices,
then libvirt will internally keep that device on both the interface
list *and* the hostdev list for the domain. One of the places this
comes in handy is when a new device is being added and libvirt wants
to find a unique "alias" name for it - it just scans through the
hostdev array and makes sure it picks a name that doesn't match the
alias of any device in that array.
However, when libvirtd was restarted, if there was an <interface
type='network'> with the network being a hostdev pool, the device
would not be added to the reconstructed internal hostdev array, so its
alias would not be found during a scan of the hostdev array, thus
attempts to add a new hostdev (or <interface type='hostdev'> or
<interface type='network'>) would result in a message like this:
internal error: unable to execute QEMU command 'device_add':
Duplicate ID 'hostdev0' for device
This patch simply fixes the existing code in the domain XML parser
that fixes up the hostdev array in the case of <interface
type='hostdev'> to do the same thing in the case of <interface
type='network'> with a hostdev network.
This bug has existed since the very first addition of hostdev networks
to libvirt (0.10.0).
This eliminates the misleading error message that was being logged
when a vfio hostdev hotplug failed:
error: unable to set user and group to '107:107' on '/dev/vfio/22':
No such file or directory
as documented in:
https://bugzilla.redhat.com/show_bug.cgi?id=1035490
Commit ee414b5d (pushed as a fix for Bug 1016511 and part of Bug
1025108) replaced the single call to
virSecurityManagerSetHostdevLabel() in qemuDomainAttachHostDevice()
with individual calls to that same function in each
device-type-specific attach function (for PCI, USB, and SCSI). It also
added a corresponding call to virSecurityManagerRestoreHostdevLabel()
in the error handling of the device-type-specific functions, but
forgot to remove the common call to that from
qemuDomainAttachHostDevice() - this resulted in a duplicate call to
virSecurityManagerRestoreHostdevLabel(), with the second occurrence
being after (e.g.) a PCI device has already been re-attached to the
host driver, thus destroying some of the device nodes / links that we
then attempted to re-label (e.f. /dev/vfio/22) and generating an error
log that obscured the original error.
This resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=1035490
virProcessSetMaxMemLock() (which is a wrapper over prlimit(3)) expects
the memory size in bytes, but libvirt's domain definition (which was
being used by qemuDomainAttachHostPciDevice()) stores all memory
tuning parameters in KiB. This was being accounted for when setting
MaxMemLock at domain startup time (so cold-plugged devices would
work), but not for hotplug.
This patch simplifies the few lines that call
virProcessSetMemMaxLock(), and multiply the amount * 1024 so that
we're locking the correct amount of memory.
What remains a mystery to me is why hot-plug of a managed='no' device
would succeed (at least on my system) while managed='yes' would
fail. I guess in one case the memory was coincidentally already
resident and in the other it wasn't.
there is a segfault in libxl logging in libxl_ctx_free when domain
create fail. because the log output handler vmessage is freed by
xtl_logger_destroy before libxl_ctx_free in virDomainObjListRemove.
move xtl_logger_destroy after libxl_ctx_free could fix this bug.

D-bus introduced some changes in its locking code. Overriding the init
function skips the new locking init and thus crashes later in libvirt
test. Removing the function makes the test pass again.
Move the code around so that the forward declaration isn't needed. Also
fix code style of the opening brace of the function by moving it to a
separate line.
Recent addition of the gluster pool type omitted fixing the virsh and
virConnectListAllStoragePool filters. A typecast of the converting
function in virsh showed that also the sheepdog pool was omitted in the
command parser.
This patch adds gluster pool filtering support and fixes virsh to
properly convert all supported storage pool types. The added typecast
should avoid doing such mistakes in the future.
Old versions of CIL did not understand the 'bool' data type,
but at least 1.7.3 does now cope. We can remove the old hack
which redefined bool and no longer compiles successfully.

Currently the virDBusAddWatch does
virEventAddHandle(fd, flags,
virDBusWatchCallback,
watch, NULL);
dbus_watch_set_data(watch, info, virDBusWatchFree);
Unfortunately this is racy - since the event loop is in a
different thread, the virDBusWatchCallback method may be
run before we get to calling dbus_watch_set_data. We must
reverse the order of these calls

Starting from commit 2e82c18c in Xen (will be included in Xen 4.4)
both libxl_get_max_cpus() and libxl_get_max_nodes() start returning
a proper libxl error code, in case of failure. This patch fixes
this in the libxl driver.
Note that, although it is now basically impossible for them to return
0, that would, theoretically, still be wrong. Also, checking that the
returned value is '<= 0' makes the code correct for both Xen 4.4 and
Xen 4.3 (and 4.2), and that is why we go for it (rather than
just '< 0').

When undefining a VM with storage the man page doesn't explicitly
mention that the volumes need to be a part of the storage pool otherwise
it won't work.
On a system that is enforcing FIPS, most libraries honor the
current mode by default. Qemu, on the other hand, refused to
honor FIPS mode unless you add the '-enable-fips' command
line option; worse, this option is not discoverable via QMP,
and is only present on binaries built for Linux. So, if we
detect FIPS mode, then we unconditionally ask for FIPS; either
qemu is new enough to have the option and then correctly
cripple insecure VNC passwords, or it is so old that we are
correctly avoiding a FIPS violation by preventing qemu from
starting. Meanwhile, if we don't detect FIPS mode, then
omitting the argument is safe whether the qemu has the option
(but it would do nothing because FIPS is disabled) or whether
qemu lacks the option (including in the case where we are not
running on Linux).
The testsuite was a bit interesting: we don't want our test
to depend on whether it is being run in FIPS mode, so I had
to tweak things to set the capability bit outside of our
normal interaction with capability parsing.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1035474
* src/qemu/qemu_capabilities.h (QEMU_CAPS_ENABLE_FIPS): New bit.
* src/qemu/qemu_capabilities.c (virQEMUCapsInitQMP): Conditionally
set capability according to detection of FIPS mode.
* src/qemu/qemu_command.c (qemuBuildCommandLine): Use it.
* tests/qemucapabilitiestest.c (testQemuCaps): Conditionally set
capability to test expected output.
* tests/qemucapabilitiesdata/caps_1.2.2-1.caps: Update list.
* tests/qemucapabilitiesdata/caps_1.6.0-1.caps: Likewise.

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.
The option has been broken since the introduction in commit 3a2fc27.

Systemd specified that any /dev/pts/NNN device on which it
is expected to spawn a agetty login, should be listed in
the 'container_ttys' env variable. It should just contain
the relative paths, eg 'pts/0' not '/dev/pts/0' and should
be space separated.

Currently, 'vol-resize --allocate' allocates new space at the
vol->capacity offset. But the vol->capacity is not necessarily the same
as vol->allocation. For instance:.
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 1.00 GiB 1.00 GiB
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 2G
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 2.00 GiB 1.00 GiB
So, if we want to allocate more bytes, so the file is say 3G big, the
real allocated size is 2G actually:
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 2.00 GiB
This commit uses the correct vol->allocation instead of incorrect
vol->capacity, so the output of the commands above looks like this:
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 3.00 GiB
Moreover, if the '--alocate' flag was used, we must update the
vol->allocation member in storageVolResize API too, not just
vol->capacity.

vmx/vmx.c ignores the transient attribute on the disk xml format. This patch
adds a 1-1 relationship between it and [disk].mode = "independent-nonpersistent".
The other modes are ignored as before. It works in my testing.

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
the wrong one.

Commit ff76566 moved around things in the specfiles to put
driver-specific files into their appropriate sub-packages (when
with_driver_modules == 1), but accidentally changed things so that the
deamon-driver-network and daemon-config-network files were only
included in a package when with_driver_modules == 0. This broke "make
rpm" on fedora (where with_driver_modules == 1).
This patch follows the pattern (already used for the files in other
sub-modules) of duplicating the files for the main package
(!with_driver_modules) and the sub-package (with_driver_modules).
