Daniel's patch works with gcc and CFLAGS containing -O (the
autoconf default), but fails with non-gcc or with other
CFLAGS (such as -g), since c-ctype.h declares c_isdigit as
a macro only for certain compilation settings.

* src/Makefile.am (libvirt_parthelper_LDFLAGS): Add gnulib
library, for when c_isdigit is not a macro.
* src/storage/parthelper.c (main): Avoid out-of-bounds
dereference, noticed by Jim Meyering.

Disks with a trailing digit in their path (eg /dev/loop0 or
/dev/dm0) have an extra 'p' appended before the partition
number (eg, to form /dev/loop0p1 not /dev/loop01). Fix the
partition lookup to append this extra 'p' when required

* src/storage/parthelper.c: Add a 'p' before partition
  number if required

Otherwise, a malicious packet could cause a DoS via spurious
out-of-memory failure.

* src/uml/uml_driver.c (umlMonitorCommand): Validate that incoming
data is reliable before using it to allocate/dereference memory.
Don't report bogus errno on short read.
Reported by Jim Meyering.

Report that libvirt was built without that driver instead of
trying to connect to a libvirtd, when we know that this is
going to fail.

Otherwise this will segfault if DISPLAY is not defined.

Otherwise this will segfault if PATH is not defined.

This patch adds two new parameters to the vol-create-as command:

 --backing-vol <volume-name-or-key-or-path>
 --backing-vol-format <format-of-backing-vol>

  virsh # vol-create-as guest_images_lvm snapvol1 5G --backing-vol \
              rhel6vm1lun1
  Vol snapvol1 created

  virsh # vol-create-as image_dir qcow2snap2 5G --format qcow2 \
              --backing-vol imagevol1.qcow2 \
              --backing-vol-format qcow2
  Vol qcow2snap2 created

Additionally, the virsh man page update fixes incorrect snapshot
parameters that were included in my prior bulk volume command patch.

On Fedora 13 with sufficient mingw32-* packages installed, running
./autobuild.sh failed to cross-compile to mingw because
mingw32-pthreads installed a broken <pthread.h>.  With that
issue fixed, the build still failed due to use of O_SYNC.
Meanwhile, recent .spec.in changes got out of sync.

* bootstrap.conf (gnulib_modules): Add fcntl-h, for O_SYNC.
* .gnulib: Update to latest, to work around buggy pthreads-win32
library.
* bootstrap: Import latest from gnulib.
* mingw32-libvirt.spec.in: Distribute new file.

* src/util/threads.c (includes) [WIN32]: On mingw, favor native
threading over pthreads-win32 library.
* src/util/thread.h [WIN32] Likewise.
Suggested by Daniel P. Berrange.

When a disk is on a root squashed NFS server, it may not be
possible to stat() the disk file in virCgroupAllowDevice.
The virStorageFileGetMeta method may also fail to extract
the parent backing store. Both of these errors have to be
ignored to avoid breaking NFS deployments

* src/qemu/qemu_driver.c: Ignore errors in cgroup setup to
   keep root squash NFS happy

With libvirt and virsh now being used for much more than Xen, this
patch removes the outdated reference to Xen in the file header.

Allow to specify a proxy to be used by libcurl.

Pass a struct containing the parameters instead of passing each
one individually. This make future extensions a bit simpler.

This patch also includes the new vol-pool command.

This patch adds a new "vol-pool" command to virsh, to round out the
identifier conversion functions for volumes in virsh.  Now it is
possible to work with volumes when starting from just a volume key
or volume path.

* tools/virsh.c (opts_create): Add --paused option.
(cmdCreate): Pass appropriate flag.
* tools/virsh.pod: Document it.

Some guests (eg with badly configured grub, or Windows' installation cd)
require quick response from the console user. That's why we have a
"launchPaused" option in vdsm.

To implement it via libvirt, we need to ask libvirt not to call
qemuMonitorStartCPUs() after starting qemu.  Calling virDomainStop
immediately after the domain is up is inherently raceful.

* src/qemu/qemu_driver.c (qemudStartVMDaemon): Add new parameter;
all callers adjusted.
(qemudDomainCreate): Implement support for new flag.

* include/libvirt/libvirt.h.in (virDomainCreateFlags): Add
VIR_DOMAIN_START_PAUSED.
* src/libvirt.c (virDomainCreateXML): Update documentation.
* src/lxc/lxc_driver.c (lxcDomainCreateAndStart): Reject new flag
as unimplemented.
* src/opennebula/one_driver.c (oneDomainCreateAndStart):
Likewise.
* src/openvz/openvz_driver.c (openvzDomainCreateXML): Likewise.
* src/phyp/phyp_driver.c (phypDomainCreateAndStart): Likewise.
* src/qemu/qemu_driver.c (qemudDomainCreate): Likewise.
* src/test/test_driver.c (testDomainCreateXML): Likewise.
* src/uml/uml_driver.c (umlDomainCreate): Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainCreateXML): Likewise.
* src/xen/xend_internal.c (xenDaemonCreateXML): Likewise.

* This patch is a modification of a patch submitted by Nigel Jones.
  It fixes several memory leaks on device addition/removal:

1. Free the virNodeDeviceDefPtr in udevAddOneDevice if the return
   value is non-zero

2. Always release the node device reference after the device has been
   processed.

* Refactored for better readability per the suggestion of clalance

* Fix broken rng schema
* Add test input & output files

* Use virBufferEscapeString() per Dan B.

The virtio serial changes broke the test suite because they forgot
to add the new address attribute to the domain XML schema. The
xml2xml test also broke because the XML no longer roundtrips. This
is due to testing of auto-addition of <controller> elements. Split
that test case off into a separate XML file to avoid breakage

* docs/schemas/domain.rng: Allow port number for virtio serial addresses
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
  tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Revert to
  a simple config to avoid breaking xml2xml test
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.xml,
  tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.args: Add
  complex test case for auto-controller addition for xml2argv test
* tests/qemuxml2argvtest.c: Add channel-virtio-auto test

A look at the QEMU source revealed the missing bits of info about
the VPC file format, so we can enable this now

* src/util/storage_file.c: Enable VPC format, providing version
  and disk size offset fields

When an attempt to hotplug a PCI device to a guest fails,
the device was left attached to pci-stub. It is neccessary
to reset the device and then attach it to the host driver
again.

* src/qemu/qemu_driver.c: Reattach PCI device to host if
  hotadd fails

The restore code is done in places where errors cannot be
raised, since they will overwrite over pre-existing errors.

* src/security/security_selinux.c: Only warn about failures
  in label restore, don't report errors

Any output at all from device_add indicates an error in the
command execution. Thus it needs to check for reply != ""

* src/qemu/qemu_monitor_text.c: Fix reply check for errors
  to treat any output as an error

HAL is deprecated and UDEV is the future. Thus if both
options are compiled, we should prefer use of UDEV over
HAL

* src/node_device/node_device_driver.c: Switch init
  order to try UDEV first, then HAL

When SELinux is running in MLS mode, libvirtd will have a
different security level to the VMs. For libvirtd to be
able to connect to the monitor console, the client end of
the UNIX domain socket needs a different label. This adds
infrastructure to set the socket label via the security
driver framework

* src/qemu/qemu_driver.c: Call out to socket label APIs in
  security driver
* src/qemu/qemu_security_stacked.c: Wire up socket label
  drivers
* src/security/security_driver.h: Define security driver
  entry points for socket labelling
* src/security/security_selinux.c: Set socket label based on
  VM label

The network driver is not doing correct checking for
duplicate UUID/name values. This introduces a new method
virNetworkObjIsDuplicate, based on the previously
written virDomainObjIsDuplicate.

* src/conf/network_conf.c, src/conf/network_conf.c,
  src/libvirt_private.syms: Add virNetworkObjIsDuplicate,
* src/network/bridge_driver.c: Call virNetworkObjIsDuplicate
  for checking uniqueness of uuid/names

The storage pool driver is mistakenly using the error code
VIR_ERR_INVALID_STORAGE_POOL which is for diagnosing invalid
pointers. This patch switches it to use VIR_ERR_NO_STORAGE_POOL
which is the correct code for cases where the storage pool does
not exist

* src/storage/storage_driver.c: Replace VIR_ERR_INVALID_STORAGE_POOL
  with VIR_ERR_NO_STORAGE_POOL

The storage pool driver is not doing correct checking for
duplicate UUID/name values. This introduces a new method
virStoragePoolObjIsDuplicate, based on the previously
written virDomainObjIsDuplicate.

* src/conf/storage_conf.c, src/conf/storage_conf.c,
  src/libvirt_private.syms: Add virStoragePoolObjIsDuplicate,
* src/storage/storage_driver.c: Call virStoragePoolObjIsDuplicate
  for checking uniqueness of uuid/names

The domain parsing code would auto-add a virtio serial controller
if it saw any virtio serial channel defined. Unfortunately it
always added a controller with index=0, even if the channel address
specified an index != 0. It only added one controller, even if
multiple controllers were referenced by channels. Finally, it let
the ports+vectors parameters initialize to zero instead of -1, which
prevented the controllers accepting any ports.

* src/conf/domain_conf.c: Initialize ports+vectors when adding
  virtio serial controllers. Add all neccessary virtio serial
  controllers, instead of hardcoding controller 0
* qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
  qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Expand to
  test controller auto-add behaviour

To ensure that the device addressing scheme is stable across
hotplug/unplug, all virtio serial channels needs to have an
associated port number in their address. This is then specified
to QEMU using the nr=NNN parameter

* src/conf/domain_conf.c, src/conf/domain_conf.h: Parsing
  for port number in vioserial address types.
* src/qemu/qemu_conf.c: Set 'nr=NNN' parameter with virtio
  serial port number
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
  tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Expand
  data set to ensure coverage of port addressing

QEMU upstream decided against adding a 'reason' field to
the block IO event in QMP. Disable this code to remove a
annoying warning message. It will be renabled when the
error string reason is re-introduced in QEMU

When libvirtd exits it is leaving UNIX domain sockets on
the filesystem. These need to be removed.

The qemudInitPaths() method has signficant code churn to
switch from using a pre-allocated buffer on the stack, to
dynamically allocating on the heap.

* daemon/libvirtd.c, daemon/libvirtd.h: Store a reference
  to the UNIX domain socket path and unlink it on shutdown

Refactor to update AppArmor security driver to adjust profile for
save/restore. This addresses the following bugs:

 https://bugzilla.redhat.com/show_bug.cgi?id=529363
 https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/457716

Adjust args to qemudStartVMDaemon() to also specify path to stdin_fd,
so this can be passed to the AppArmor driver via SetSecurityAllLabel().

This updates all calls to qemudStartVMDaemon() as well as setting up
the non-AppArmor security driver *SetSecurityAllLabel() declarations
for the above. This is required for the following
"apparmor-fix-save-restore" patch since AppArmor resolves the passed
file descriptor to the pathname given to open().

* .mailmap: Map a stray commit-author email address to the canonical one.
