These are the first async events in the qemu protocol, so this patch looks rather big compared to most RPC additions. However, a large majority of this patch is just mechanical copy-and-paste from recently-added network events.

This patch continues the earlier conversion made for network events, with a goal of introducing server-side event filtering in a later patch.

Right now, the daemon side of RPC events is hard-coded to at most one callback per eventID. But when there are hundreds of domains or networks coupled and multiple conections, then sending every event to every connection that wants an event, even for the connections that only care about events for a particular object, is inefficient. In order to track more than one callback in the server, we need to store callbacks by more than just their eventID. This patch rearranges the daemon side to store network callbacks in a dynamic array, which can eventually be used for multiple callbacks of the same eventID, although actual behavior is unchanged without further patches to the RPC protocol. For ease of review, domain events are saved for a later patch, as they touch more code. While at it, fix a bug where a malicious client could send a negative eventID to cause network event registration to access outside of array bounds (thankfully not a CVE, since domain events were already doing the bounds check, and since network events have not been released). * daemon/libvirtd.h (daemonClientPrivate): Alter the tracking of network events. * daemon/remote.c (daemonClientEventCallback): New struct.

Although this is a public API break, it only affects users that were compiling against *_LAST values, and can be trivially worked around without impacting compilation against older headers, by the user defining VIR_ENUM_SENTINELS before using libvirt.h. It is not an ABI break, since enum values do not appear as .so entry points. Meanwhile, it prevents users from using non-stable enum values without explicitly acknowledging the risk of doing so.

The libvirtd daemon had a few crude system tap probes. Some of these were broken during the RPC rewrite. The new modular RPC code is structured in a way that allows much more effective tracing. Instead of trying to hook up the original probes, define a new set of probes for the RPC and event code. The master probes file is now src/probes.d. This contains probes for virNetServerClientPtr, virNetClientPtr, virSocketPtr virNetTLSContextPtr and virNetTLSSessionPtr modules. Also add probes for the poll event loop. The src/dtrace2systemtap.pl script can convert the probes.d file into a libvirt_probes.stp file to make use from systemtap much simpler. The src/rpc/gensystemtap.pl script can generate a set of systemtap functions for translating RPC enum values into printable strings. This works for all RPC header enums (program, type, status, procedure) and also the authentication enum The PROBE macro will automatically generate a VIR_DEBUG statement, so any place with a PROBE can remove any existing manual DEBUG statements. * daemon/libvirtd.stp, daemon/probes.d: Remove obsolete probing * daemon/libvirtd.h: Remove probe macros * daemon/Makefile.am: Remove all probe buildings/install * daemon/remote.c: Update authentication probes * src/dtrace2systemtap.pl, src/rpc/gensystemtap.pl: Scripts to generate STP files * src/internal.h: Add probe macros * src/probes.d: Master list of probes * src/rpc/virnetclient.c, src/rpc/virnetserverclient.c, src/rpc/virnetsocket.c, src/rpc/virnettlscontext.c, src/util/event_poll.c: Insert probe points, removing any DEBUG statements that duplicate the info

This guts the libvirtd daemon, removing all its networking and RPC handling code. Instead it calls out to the new virServerPtr APIs for all its RPC & networking work As a fallout all libvirtd daemon error reporting now takes place via the normal internal error reporting APIs.

Adds initial support for dtrace static probes in libvirtd daemon, assuming use of systemtap dtrace compat shim on Linux. The probes are inserted for network client connect, disconnect, TLS handshake states and authentication protocol states. This can be tested by running the xample program and then attempting to connect with any libvirt client (virsh, virt-manager, etc). # stap examples/systemtap/client.stp Client fd=44 connected readonly=0 Client fd=44 auth polkit deny pid:24997,uid:500 Client fd=44 disconnected Client fd=46 connected readonly=1 Client fd=46 auth sasl allow test Client fd=46 disconnected The libvirtd.stp file should also really not be required, since it is duplicated info that is already available in the main probes.d definition file. A script to autogenerate the .stp file is needed, either in libvirtd tree, or better as part of systemtap itself. * Makefile.am: Add examples/systemtap subdir * autobuild.sh: Disable dtrace for mingw32 * configure.ac: Add check for dtrace * daemon/.gitignore: Ignore generated dtrace probe file * daemon/Makefile.am: Build dtrace probe header & object files * daemon/libvirtd.stp: SystemTAP convenience probeset * daemon/libvirtd.c: Add connect/disconnect & TLS probes * daemon/remote.c: Add SASL and PolicyKit auth probes * daemon/probes.d: Master probe definition * daemon/libvirtd.h: Add convenience macro for probes so that compilation is a no-op when dtrace is not available * examples/systemtap/Makefile.am, examples/systemtap/client.stp Example systemtap script using dtrace probe markers * libvirt.spec.in: Enable dtrace on F13/RHEL6 * mingw32-libvirt.spec.in: Force disable dtrace

Since we are adding a new "per-hypervisor" protocol, we make it so that the qemu remote protocol uses a new PROTOCOL and PROGRAM number. This allows us to easily distinguish it from the normal REMOTE protocol. This necessitates changing the proc in remote_message_header from a "remote_procedure" to an "unsigned", which should be the same size (and thus preserve the on-wire protocol). Changes since v1: - Fixed up a couple of script problems in remote_generate_stubs.pl - Switch an int flag to a bool in dispatch.c Changes since v2: - None Changes since v3: - Change unsigned proc to signed proc, to conform to spec Signed-off-by: NChris Lalancette <clalance@redhat.com>

This wires up the remote driver to handle the new events APIs. The public API allows an application to request a callback filters events to a specific domain object, and register multiple callbacks for the same event type. On the wire there are two strategies for this - Register multiple callbacks with the remote daemon, each with filtering as needed - Register only one callback per event type, with no filtering Both approaches have potential inefficiency. In the first scheme, the same event gets sent over the wire many times if multiple callbacks are registered. With the second scheme, unneccessary events get sent over the wire if a per-domain filter is set on the client. The second scheme is far easier to implement though, so this patch takes that approach. * daemon/dispatch.h: Don't export remoteRelayDomainEvent since it is no longer needed for unregistering callbacks, instead the unique callback ID is used * daemon/libvirtd.c, daemon/libvirtd.h: Track and unregister callbacks based on callback ID, instead of function pointer * daemon/remote.c: Switch over to using virConnectDomainEventRegisterAny instead of legacy virConnectDomainEventRegister function. Refactor remoteDispatchDomainEventSend() to cope with arbitrary event types * src/driver.h, src/driver.c: Move verify() call into source file instead of header, to avoid polluting the global namespace with the verify function name * src/remote/remote_driver.c: Implement new APIs for event registration. Refactor processCallDispatchMessage() to cope with arbitrary incoming event types. Merge remoteDomainQueueEvent() into processCallDispatchMessage() to avoid duplication of code. Rename remoteDomainReadEvent() to remoteDomainReadEventLifecycle() * src/remote/remote_protocol.x: Define wire format for the new virConnectDomainEventRegisterAny and virConnectDomainEventDeregisterAny functions

The 'int virInterfaceIsActive()' method was directly returning the value of the 'int active:1' bitfield in virIntefaceDefPtr. A bitfield with a signed integer, will hold the values 0 and -1, not 0 and +1 as might be expected. This meant that virInterfaceIsActive() was always returning -1 when the interface was active, not +1 & thus all callers thought an error had occurred. To protect against this kind of mistake again, change all bitfields to be unsigned ints * daemon/libvirtd.h, src/conf/domain_conf.h, src/conf/interface_conf.h, src/conf/network_conf.h: Change bitfields to unsigned int.

The virStateInitialize() call for starting up stateful drivers may require that the event loop is running already. This it is neccessary to start the event loop before this call. At the same time, network clients must not be processed until afte virStateInitialize has completed. The qemudListenUnix() and remoteListenTCP() methods must therefore not register file handle watches, merely open the network sockets & listen() on them. This means clients can connected and are queued, pending completion of initialization The qemudRunLoop() method is moved into a background thread that is started early to allow access to the event loop during driver initialization. The main process thread leader pretty much does nothing once the daemon is running, merely waits for the event loop thread to quit * daemon/libvirtd.c, daemon/libvirtd.h: Move event loop into a background thread * daemon/THREADING.txt: Rewrite docs to better reflect reality
