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
them. This patch removes these empty lines from all invocations of the
following macros:
VIR_DEBUG
VIR_DEBUG0
VIR_ERROR
VIR_ERROR0
VIR_INFO
VIR_WARN
VIR_WARN0

udev doesn't prefix USB product/vendor info with '0x', so the
strtol conversions were wrong for the product field (vendor already
set the correct base). Make the change for PCI product/vendor as
well to be safe.
This fixes USB device assignment via virt-manager.
This invalid free results in heap corruption. Some symptoms I saw
because of this were libvirtd crashing and virt-manager hanging
while trying to enumerate devices.
* src/node_device/node_device_driver.c (update_driver_name): The
previous code would write one byte beyond the end of the 4KiB
stack buffer when presented with a symlink value of exactly that
length (very unlikely). Remove the automatic buffer and use
virFileResolveLink in place of readlink. Suggested by Daniel Veillard.
src/node_device/node_device_udev.c was using a function available only
on the daemon code, fix this and use the function available globally
* src/node_device/node_device_udev.c: replace use of virEventAddHandleImpl
by virEventAddHandle
Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
I realized that I inadvertently added a member to the def struct to
contain each device's sysfs path when there was an existing member in the
dev struct for "OS specific path to device metadat, eg sysfs" Since the
udev backend needs to record the sysfs path while it's in the process of
creating the device, before the dev struct gets allocated, I chose to
remove the member from the dev struct.

src/node_device/node_device_driver.c src/node_device/node_device_hal.c
src/node_device/node_device_udev.c: remove devicePath from the
structure and use def->sysfs_path instead
The HAL driver returns a fatal error code in the case where HAL
is not running. This causes the entire libvirtd daemon to quit
which isn't desirable. Instead it should simply disable the HAL
driver
* src/node_device/node_device_hal.c: Quietly disable HAL if it is
not running
There is a race condition in HAL driver startup where the callback
can get triggered before we have finished startup. This then causes
a deadlock in the driver.
* src/node_device/node_device_hal.c: RElease driver lock before
registering DBus callbacks
uses libpciaccess to provide human readable names for PCI vendor and
device IDs
* configure.in: add a requirement for libpciaccess >= 0.10.0
* src/Makefile.am: add the associated compilation flags and link
* src/node_device/node_device_udev.c: lookup the libpciaccess for
vendor name and product name based on their ids
* configure.in src/Makefile.am: remove the configuration check and
build instructions
* src/node_device/node_device_devkit.c: removed the module
* src/node_device/node_device_driver.c src/node_device/node_device_driver.h:
removed references to the old backend
* src/conf/node_device_conf.h src/conf/node_device_conf.c: add specific
support for SCSI target in node device capabilities
* src/node_device/node_device_udev.c: add some extra detection code
when handling udev output
* configure.in: add new --with-udev, disabled by default, and requiring
libudev > 145
* src/node_device/node_device_udev.c src/node_device/node_device_udev.h:
the new node device backend
* src/node_device/node_device_linux_sysfs.c: moved node_device_hal_linux.c
to a better file name
* src/conf/node_device_conf.c src/conf/node_device_conf.h: add a couple
of fields in node device definitions, and an API to look them up,
remove a couple of unused fields from previous patch.
* src/node_device/node_device_driver.c src/node_device/node_device_driver.h:
plug the new driver
* po/POTFILES.in src/Makefile.am src/libvirt_private.syms: add the new
files and symbols

review and those are the fixes correcting the problems
The LXC driver was mistakenly returning -1 for lxcStartup()
in scenarios that are not an error. This caused the libvirtd
to quit for unprivileged users. This fixes the return code
of LXC driver, and also adds a "name" field to the virStateDriver
struct and logging to make it easier to find these problems
in the future
* src/driver.h: Add a 'name' field to state driver to allow
easy identification during failures
* src/libvirt.c: Log name of failed driver for virStateInit
failures
* src/lxc/lxc_driver.c: Don't return a failure code for
lxcStartup() if LXC is not available on this host, simply
disable the driver.
