Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'
followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.
* src/util/logging.h (DEBUG, DEBUG0): Delete.
* daemon/libvirtd.h (qemudDebug): Likewise.
* global: Change remaining clients over to VIR_DEBUG counterpart.
Most of te VIR_INFO calls in the udev driver are only relevant
to developers so can switch to VIR_DEBUG. Failure to initialize
libpciaccess though is a fatal error
* src/node_device/node_device_udev.c: Adjust log levels
The Linux kernel headers don't have a value for SCSI type 12,
but HAL source code shows this to be a 'raid'. Add workaround
for this type. Lower log level for unknown types since
this is not a fatal error condition. Include the device sysfs
path in the log output to allow identification of which device
has problems.
* src/node_device/node_device_udev.c: Add SCSI RAID type
libpciaccess has many bugs in its pci_system_init/cleanup
functions that makes calling them multiple times unwise.
eg it will double close() FDs, and leak other FDs.
* src/node_device/node_device_udev.c: Only initialize
libpciaccess once
The udev driver does not update a PCI device with its SR-IOV capabilities,
when applicable, the way the hal driver does. As a result, dumping the
device's XML will not include the relevant physical or virtual function
information.
With this patch, the XML is correct:

This patch adds a mode_t parameter to virFileWriteStr().
If mode is different from 0, virFileWriteStr() will try
to create the file if it doesn't exist.
* src/util/util.h (virFileWriteStr): Alter signature.
* src/util/util.c (virFileWriteStr): Allow file creation.
* src/network/bridge_driver.c (networkEnableIpForwarding)
(networkDisableIPV6): Adjust clients.
* src/node_device/node_device_driver.c
(nodeDeviceVportCreateDelete): Likewise.
* src/util/cgroup.c (virCgroupSetValueStr): Likewise.
* src/util/pci.c (pciBindDeviceToStub, pciUnBindDeviceFromStub):
Likewise.
Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
node_device/node_device_driver.c: In function 'nodeDeviceVportCreateDelete':
node_device/node_device_driver.c:423: error: implicit declaration of function 'stat' [-Wimplicit-function-declaration]
* src/node_device/node_device_driver.c (includes): Add <sys/stat.h>.
Some kernels, such as the one used in RHEL-5, have vport_create and
vport_delete operation files in /sys/class/scsi_host/hostN directory
instead of /sys/class/fc_host/hostN. Let's check both paths for
compatibility reasons.
This also removes unnecessary '/' characters from sysfs paths containing
LINUX_SYSFS_FC_HOST_PREFIX.
We only use libpciaccess for resolving device product/vendor. If
initializing the library fails (say if using qemu:///session), don't
warn so loudly, and carry on as usual.
* 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
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
* It appears that the udev event for HBA creation arrives before the
associated sysfs data is fully populated, resulting in bogus data
for the nodedev entry until the entry is refreshed. This problem is
particularly troublesome when creating NPIV vHBAs because it results
in libvirt failing to find the newly created adapter and waiting for
the full timeout period before erroneously failing the create
operation. This patch forces an update before any attempt to use
any scsi_host nodedev entry.
* If a nodedev has a parent that we don't want to display, we should
continue walking up the udev device tree to see if any of its
earlier ancestors are devices that we display. It makes the tree
much nicer looking than having a whole lot of devices hanging off
the root node.
* Incorporated Jim's feedback (v1 & v2)
* Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.
* Made comment more detailed about the wired case to explain better
how it differentiates between wired network interfaces and USB
devices.
Allow for a host UUID in the capabilities XML. Local drivers
will initialize this from the SMBIOS data. If a sanity check
shows SMBIOS uuid is invalid, allow an override from the
libvirtd.conf configuration file
* daemon/libvirtd.c, daemon/libvirtd.conf: Support a host_uuid
configuration option
* docs/schemas/capability.rng: Add optional host uuid field
* src/conf/capabilities.c, src/conf/capabilities.h: Include
host UUID in XML
* src/libvirt_private.syms: Export new uuid.h functions
* src/lxc/lxc_conf.c, src/qemu/qemu_driver.c,
src/uml/uml_conf.c: Set host UUID in capabilities
* src/util/uuid.c, src/util/uuid.h: Support for host UUIDs
* src/node_device/node_device_udev.c: Use the host UUID functions
* tests/confdata/libvirtd.conf, tests/confdata/libvirtd.out: Add
new host_uuid config option to test
We were over-writing a pointer without freeing it in
case of a disk device, leading to a memory leak.

All other uses of get_str_prop in this file that ignored
failure explicitly cast to void.
* src/node_device/node_device_hal.c (dev_create): Silence coverity
warning.
The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr
from all APIs in node_device_conf.{h,c} and update all callers to
match
The original udev node device backend neglected to lock the driverState
struct containing the device list when adding and removing devices
* src/node_device/node_device_udev.c: add necessary locks in
udevRemoveOneDevice() and udevAddOneDevice()
udevGetUintProperty was called with base set to 0 for busnum and devnum.
With base 0 strtoul parses the number as octal if it start with a 0. But
busnum and devnum are decimal and udev returns them padded with leading
zeros. So strtoul parses them as octal. This works for certain decimal
values like 001-007, but fails for values like 008.
Change udevProcessUSBDevice to use base 10 for busnum and devnum.
it causes a NULL-dereference on some systems like Solaris 10.
* src/node_device/node_device_linux_sysfs.c. Include <stdlib.h>.
(get_sriov_function): Use canonicalize_file_name, not realpath.
* bootstrap (modules): Add canonicalize-lgpl.
This fixes a segfault when the event handler is called after shutdown
when the global driver state is NULL again.
Also fix a locking issue in an error path.
Two files were using functions from <sys/stat.h> but not including
in. Most of the time they got this automatically via another header,
but certain build flag combinations can reveal the problem
* src/lxc/lxc_container.c, src/node_device/node_device_linux_sysfs.c:
Add <sys/stat.h>
I noticed some debug messages are printed with an empty lines after

VIR_WARN0
