This new security driver is responsible for managing UID/GID changes
to the QEMU process, and any files/disks/devices assigned to it.
* qemu/qemu_conf.h: Add flag for disabling automatic file permission
changes
* qemu/qemu_security_dac.h, qemu/qemu_security_dac.c: New DAC driver
for QEMU guests
* Makefile.am: Add new files
The latter is not officially "wrong", but *is* terribly anachronistic.
I think automake documentation or comments call that syntax obsolescent.
* cfg.mk (_makefile_at_at_check_exceptions): Exempt @SCHEMADIR@
and @SYSCONFDIR@ uses -- there are no Makefile variables for those.
* docs/Makefile.am: Use $(INSTALL), not @INSTALL@.
* examples/dominfo/Makefile.am: Similar.

* proxy/Makefile.am: Similar.
* python/Makefile.am: Similar.
* python/tests/Makefile.am: Similar.

* tests/Makefile.am: Similar.
All other stateful drivers are linked directly to libvirtd
instead of libvirt.so. Link the secret driver to libvirtd too.
* daemon/Makefile.am: link the secret driver to libvirtd
* daemon/libvirtd.c: add #ifdef WITH_SECRETS blocks
* src/Makefile.am: don't link the secret driver to libvirt.so
* src/libvirt_private.syms: remove the secretRegister symbol
Each driver supporting CPU selection must fill in host CPU capabilities.
When filling them, drivers for hypervisors running on the same node as
libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers,
such as VMware, need to implement their own way of getting such data.
Raw data can be decoded into virCPUDefPtr using cpuDecode() function.
When implementing virConnectCompareCPU(), a hypervisor driver can just
call cpuCompareXML() function with host CPU capabilities.
For each guest for which a driver supports selecting CPU models, it must
set the appropriate feature in guest's capabilities:
virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0)
Actions needed when a domain is being created depend on whether the
hypervisor understands raw CPU data (currently CPUID for i686, x86_64
architectures) or symbolic names has to be used.
Typical use by hypervisors which prefer CPUID (such as VMware and Xen):
- convert guest CPU configuration from domain's XML into a set of raw
data structures each representing one of the feature policies:
cpuEncode(conn, architecture, guest_cpu_config,
&forced_data, &required_data, &optional_data,
&disabled_data, &forbidden_data)
- create a mask or whatever the hypervisor expects to see and pass it
to the hypervisor
Typical use by hypervisors with symbolic model names (such as QEMU):
- get raw CPU data for a computed guest CPU:
cpuGuestData(conn, host_cpu, guest_cpu_config, &data)
- decode raw data into virCPUDefPtr with a possible restriction on
allowed model names:
cpuDecode(conn, guest, data, n_allowed_models, allowed_models)
- pass guest->model and guest->features to the hypervisor

Long ago we tried to use Fedora's lokkit utility in order to register
our iptables rules so that 'service iptables restart' would
automatically load our rules.
There was one fatal flaw - if the user had configured iptables without
lokkit, then we would clobber that configuration by running lokkit.
We quickly disabled lokkit support, but never removed it. Let's do
that now.
The 'my virtual network stops working when I restart iptables' still
remains. For all the background on this saga, see:
https://bugzilla.redhat.com/227011
* src/util/iptables.c: remove lokkit support
* configure.in: remove --enable-lokkit
* libvirt.spec.in: remove the dirs used only for saving rules for lokkit
* src/Makefile.am: ditto
* src/libvirt_private.syms, src/network/bridge_driver.c,
src/util/iptables.h: remove references to iptablesSaveRules
Initial support for the new QEMU monitor protocol using JSON
as the data encoding format instead of plain text
* po/POTFILES.in: Add src/qemu/qemu_monitor_json.c
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Hack to turn on QMP
mode. Replace with a version number check on >= 0.12 later
* src/qemu/qemu_monitor.c: Delegate to json monitor if enabled
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
impl of QMP protocol
* src/Makefile.am: Add src/qemu/qemu_monitor_json.{c,h}
This introduces simple API for handling JSON data. There is
an internal data structure 'virJSONValuePtr' which stores a
arbitrary nested JSON value (number, string, array, object,
nul, etc). There are APIs for constructing/querying objects
and APIs for parsing/formatting string formatted JSON data.
This uses the YAJL library for parsing/formatting from
http://lloyd.github.com/yajl/
* src/util/json.h, src/util/json.c: Data structures and APIs
for representing JSON data, and parsing/formatting it
* configure.in: Add check for yajl library
* libvirt.spec.in: Add build requires for yajl
* src/Makefile.am: Add json.c/h

* src/Makefile.am: node_device/node_device_udev.h was missing from
NODE_DEVICE_DRIVER_UDEV_SOURCES breaking compilation on platforms with
udev
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

files and symbols
* src/util/util.h src/util/util.c: add a new convenience macro
virBuildPath and virBuildPathInternal() function
The qemu_driver.c code should not contain any code that interacts
with the QEMU monitor at a low level. A previous commit moved all
the command invocations out. This change moves out the code which
actually opens the monitor device.
* src/qemu/qemu_driver.c: Remove qemudOpenMonitor & methods called
from it.

* src/lxc/lxc.conf: new configuration file, there is currently one
tunable "log_with_libvirtd" that controls whether an lxc controller will
log only to the container log file, or whether it will honor libvirtd's
log output configuration. This provides a way to have libvirtd and its
children log to a single file. The default is to log to the container
log file.
* src/Makefile.am libvirt.spec.in: add the new file
* src/lxc/lxc_conf.[ch] src/lxc/lxc_driver.c: read the new log value
from the configuration file and pass the log informations when
starting up a container.
* configure.in: look for AppArmor and devel
* src/security/security_apparmor.[ch] src/security/security_driver.c
src/Makefile.am: add and plug the new driver

the AppArmor security driver to manipulate AppArmor.
* po/POTFILES.in: registers the new files
* tests/Makefile.am tests/secaatest.c tests/virt-aa-helper-test:
tests for virt-aa-helper and the security driver, secaatest.c is

Pull out all the QEMU monitor interaction code to a separate
file. This will make life easier when we need to drop in a
new implementation for the forthcoming QMP machine friendly
monitor support.
Next step is to add formal APIs for each monitor command,
and remove direct commands for sending/receiving generic
data.

* src/qemu/qemu_driver.c: Remove code for monitor interaction
* src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: New
file for monitor interaction
* po/POTFILES.in: Add src/qemu/qemu_monitor_text.c
When making changes to the remote protocol, src/ is always built
first, so rpcgen should live there, to avoid having to run make
in the 'daemon/' directory before building src/

remote client build
* daemon/Makefile.am: Add -I../src/remote/ to libvirtd build
and remove rpcgen rules

src/storage_encryption_conf.h: Move to src/conf/
* src/Makefile.am: Add -Isrc/conf to the individual build targets
which need to use XML config APIs. Remove LIBXML_CFLAGS, LIBSSH2_CFLAGS
and SELINUX_CFLAGS from global INCLUDES and only have them in build
targets which actually need them. Create a libvirt_conf.la
convenience library for all config parsers
* src/hostusb.h: Remove bogus include of domain_conf.h
* tests/Makefile.am: Add -Isrc/conf. Remove bogus -I$builddir/src
since it never has any generated header files

and the qemu/*.aug files. Add test case for QEMU augeas files.
Add uninstall-local rule for files/directories created during
install. Rename install-exec-local to install-data-local.
