This patch implements the core driver and provides
- management functionality for managing the filter XMLs
- compiling the internal filter representation into ebtables rules
- applying ebtables rules on a network (tap,macvtap) interface
- tearing down ebtables rules that were applied on behalf of an
interface
- updating of filters while VMs are running and causing the firewalls to
be rebuilt
- other bits and pieces

Having a single logrotate configuration file for all hypervisors
did not work as logrotate would get confused if an hypervisor not
supported on that platform was still listed. Simplest is to split
the logrotate as separate per hypervisor files and change the
spec file to only install the ones compiled in.
* daemon/libvirtd.lxc.logrotate.in daemon/libvirtd.qemu.logrotate.in
daemon/libvirtd.uml.logrotate.in: copy and split the original
daemon/libvirtd.logrotate.in file
* daemon/Makefile.am: update to support the different files and
cleanup in sed suggested by Eric Blake
* libvirt.spec.in: only install the relevant logrotate configs
* daemon/.gitignore: update logrotate generated list
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
* configure.in daemon/Makefile.am: the --with-init-script configure
option was broken, and always defaulted based on the existence of
/etc/redhat-release. This was a systematic typo based on
mixed use of init-script and init-scripts.
Otherwise logrotate barfs:
error: error accessing /var/log/libvirt/uml: No such file or directory
error: libvirtd:1 glob failed for /var/log/libvirt/uml/*.log
error: found error in /var/log/libvirt/qemu/*.log /var/log/libvirt/uml/*.log /var/log/libvirt/lxc/*.log , skipping
* qemud/Makefile.am: always create /var/log/libvirt/{lxc,uml} when
installing the logrotate conf; not ideal, but easier than making
the logrotate conf depend on which drivers are enabled
Defines the extensions to the remote protocol for generic
data streams. Adds a bunch of helper code to the libvirtd
daemon for working with data streams.
* daemon/Makefile.am: Add stream.c/stream.h to build
* daemon/stream.c, qemud/stream.h: Generic helper functions for
creating new streams, associating streams with clients, finding
existing streams for a client and removing/deleting streams.
* src/remote/remote_protocol.x: Add a new 'REMOTE_STREAM' constant
for the 'enum remote_message_type' for encoding stream data
in wire messages. Add a new 'REMOTE_CONTINUE' constant to
'enum remote_message_status' to indicate further data stream
messsages are expected to follow. Document how the
remote_message_header is used to encode data streams
* src/remote/remote_protocol.h: Regenerate
* daemon/dispatch.c: Remove assumption that a error message
sent to client is always type=REMOTE_REPLY. It may now
also be type=REMOTE_STREAM. Add convenient method for
sending outgoing stream data packets. Log and ignore
non-filtered incoming stream packets. Add a method for
serializing a stream error message
* daemon/dispatch.h: Add API for serializing stream errors
and sending stream data packets
* daemon/qemud.h: Add struct qemud_client_stream for tracking
active data streams for clients. Tweak filter function
operation so that it accepts a client object too.
* daemon/qemud.c: Refactor code for free'ing message objects
which have been fully transmitted into separate method.
Release all active streams when client shuts down. Change
filter function to be responsible for queueing the message
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

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/
* src/Makefile.am: Add rules for rpcgen, and drop -I../daemon from
remote client build
* daemon/Makefile.am: Add -I../src/remote/ to libvirtd build
and remove rpcgen rules
* daemon/libvirtd.c: Adapt include of remote_driver.h taking
into account new -I flag
* daemon/remote_protocol.c, daemon/remote_protocol.h,
daemon/remote_protocol.x: Move to src/remote/
* daemon/rpcgen_fix.pl: Move to src/remote/rpcgen_fix.pl
* src/capabilities.c, src/capabilities.h, src/domain_conf.c,
src/domain_conf.h, src/domain_event.c, src/domain_event.h,
src/interface_conf.c, src/interface_conf.h,
src/network_conf.c, src/network_conf.h, src/node_device_conf.c,
src/node_device_conf.h, src/secret_conf.c, src/secret_conf.h,
src/storage_conf.c, src/storage_conf.h, src/storage_encryption_conf.c,
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
* daemon/Makefile.am: Add -Isrc/conf
* proxy/Makefile.am: Add -Isrc/conf and cope with renamed files
* src/hash.c: Remove bogus include of libxml/threads.h
* daemon/default-network.xml: Move to src/network/default.xml
* daemon/libvirtd_qemu.aug, daemon/test_libvirtd_qemu.aug: Move
to src/qemu/
* src/qemu.conf: Move to src/qemu/qemu.conf
* daemon/Makefile.am: Remove rules for default-nmetwork.xml and
libvirtd_qemu.aug and test_libvirtd_qemu.aug. Fix typo in
uninstall-local that would install polkit again.
* src/Makefile.am: Add rules for installing network/default.xml
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.
Only install qemu.conf if WITH_QEMU is set.
* tests/networkschematest: Update for XML location move
