The Makefile.am rules for generating RPC protocol had a couple of bugs - A instance of remote/rpcgen_fix.pl was not changed to rpc/genprotocol.pl - A dep from rpc/virnetmessage.h on the generated rpc/virnetprotocol.h was missing - The generated rpc/virnetprotocol.[ch] were not listed in MAINTAINERCLEANFILES * Makefile.am: Fix RPC protocol generation

The qemuMigrationPrepareDirect/PrepareTunnel methods accidentally set the domain job to QEMU_JOB_MIGRATION_OUT when it should have been QEMU_JOB_MIGRATION_IN. This didn't have any ill-effect, but it is none-the-less wrong. * src/qemu/qemu_migration.c: Fix job type

The code emitting taint warnings was mistakenly thinking that guests run from the QEMU session driver were tainted for having high privileges. This is of course nonsense since the session driver is always unprivileged * src/qemu/qemu_domain.c: Don't warn for high privileges in non-privileged QEMU

If an application is using libvirt + KVM as a piece of its internal infrastructure to perform a specific task, it can be desirable to guarentee the VM dies when the virConnectPtr disconnects from libvirtd. This ensures the app can't leak any VMs it was using. Adding VIR_DOMAIN_START_AUTOKILL as a flag when starting guests enables this to be done. * include/libvirt/libvirt.h.in: All VIR_DOMAIN_START_AUTOKILL * src/qemu/qemu_driver.c: Support automatic killing of guests upon connection close * tools/virsh.c: Add --autokill flag to 'start' and 'create' commands

Migration is a multi-step process 1. Begin(src) 2. Prepare(dst) 3. Perform(src) 4. Finish(dst) 5. Confirm(src) At step 2, a QEMU process is lauched in the destination to accept the incoming migration. Occasionally the process that is controlling the migration workflow aborts, and fails to call step 4, Finish. This leaves a QEMU process running on the target (albeit with paused CPUs). Unfortunately because step 2 actives a job on the QEMU process, it is unkillable by normal means. By registering the VM for autokill against the src virConnectPtr in step 2, we can ensure that the guest is forcefully killed off if the connection is closed without step 4 being invoked * src/qemu/qemu_migration.c: Register autokill in PrepareDirect and PrepareTunnel. Unregister autokill on successful run of Finish * src/qemu/qemu_process.c: Unregister autokill when stopping a process

Sometimes it is useful to be able to automatically destroy a guest when a connection is closed. For example, kill an incoming migration if the client managing the migration dies. This introduces a map between guest 'uuid' strings and virConnectPtr objects. When a connection is closed, any associated guests are killed off. * src/qemu/qemu_conf.h: Add autokill hash table to qemu driver * src/qemu/qemu_process.c, src/qemu/qemu_process.h: Add APIs for performing autokill of guests associated with a connection * src/qemu/qemu_driver.c: Initialize autodestroy map

For controlled shutdown we issue a 'system_powerdown' command to the QEMU monitor. This triggers an ACPI event which (most) guest OS wire up to a controlled shutdown. There is no equiv ACPI event to trigger a controlled reboot. This patch attempts to fake a reboot. - In qemuDomainObjPrivatePtr we have a bool fakeReboot flag. - The virDomainReboot method sets this flag and then triggers a normal 'system_powerdown'. - The QEMU process is started with '-no-shutdown' so that the guest CPUs pause when it powers off the guest - When we receive the 'POWEROFF' event from QEMU JSON monitor if fakeReboot is not set we invoke the qemuProcessKill command and shutdown continues normally - If fakeReboot was set, we spawn a background thread which issues 'system_reset' to perform a warm reboot of the guest hardware. Then it issues 'cont' to start the CPUs again * src/qemu/qemu_command.c: Add -no-shutdown flag if we have JSON support * src/qemu/qemu_domain.h: Add 'fakeReboot' flag to qemuDomainObjPrivate struct * src/qemu/qemu_driver.c: Fake reboot using the system_powerdown command if JSON support is available * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add binding for system_reset command * src/qemu/qemu_process.c: Reset the guest & start CPUs if fakeReboot is set

To facilitate creation of new clients using XDR RPC services, pull alot of the remote driver code into a set of reusable objects. - virNetClient: Encapsulates a socket connection to a remote RPC server. Handles all the network I/O for reading/writing RPC messages. Delegates RPC encoding and decoding to the registered programs - virNetClientProgram: Handles processing and dispatch of RPC messages for a single RPC (program,version). A program can register to receive async events from a client - virNetClientStream: Handles generic I/O stream integration to RPC layer Each new client program now merely needs to define the list of RPC procedures & events it wants and their handlers. It does not need to deal with any of the network I/O functionality at all.

To facilitate creation of new daemons providing XDR RPC services, pull a lot of the libvirtd daemon code into a set of reusable objects. * virNetServer: A server contains one or more services which accept incoming clients. It maintains the list of active clients. It has a list of RPC programs which can be used by clients. When clients produce a complete RPC message, the server passes this onto the corresponding program for handling, and queues any response back with the client. * virNetServerClient: Encapsulates a single client connection. All I/O for the client is handled, reading & writing RPC messages. * virNetServerProgram: Handles processing and dispatch of RPC method calls for a single RPC (program,version). Multiple programs can be registered with the server. * virNetServerService: Encapsulates socket(s) listening for new connections. Each service listens on a single host/port, but may have multiple sockets if on a dual IPv4/6 host. Each new daemon now merely has to define the list of RPC procedures & their handlers. It does not need to deal with any network related functionality at all.

This extends the basic virNetSocket APIs to allow them to have a handle to the TLS/SASL session objects, once established.

This provides a new struct that contains a buffer for the RPC message header+payload, as well as a decoded copy of the message header. There is an API for applying a XDR encoding & decoding of the message headers and payloads. There are also APIs for maintaining a simple FIFO queue of message instances. Expected usage scenarios are: To send a message msg = virNetMessageNew() ...fill in msg->header fields.. virNetMessageEncodeHeader(msg) ...loook at msg->header fields to determine payload filter virNetMessageEncodePayload(msg, xdrfilter, data) ...send msg->bufferLength worth of data from buffer To receive a message msg = virNetMessageNew() ...read VIR_NET_MESSAGE_LEN_MAX of data into buffer virNetMessageDecodeLength(msg) ...read msg->bufferLength-msg->bufferOffset of data into buffer virNetMessageDecodeHeader(msg) ...look at msg->header fields to determine payload filter virNetMessageDecodePayload(msg, xdrfilter, data) ...run payload processor * src/Makefile.am: Add to libvirt-net-rpc.la * src/rpc/virnetmessage.c, src/rpc/virnetmessage.h: Internal message handling API. * testutils.c, testutils.h: Helper for printing binary differences * virnetmessagetest.c: Validate all XDR encoding/decoding

This patch defines the basics of a generic RPC protocol in XDR. This is wire ABI compatible with the original remote_protocol.x. It takes everything except for the RPC calls / events from that protocol - The basic header virNetMessageHeader (aka remote_message_header) - The error object virNetMessageError (aka remote_error) - Two dummy objects virNetMessageDomain & virNetMessageNetwork sadly needed to keep virNetMessageError ABI compatible with the old remote_error The RPC protocol supports method calls, async events and bidirectional data streams as before * src/Makefile.am: Add rules for generating RPC code from protocol & define a new libvirt-net-rpc.la helper library * src/rpc/virnetprotocol.x: New generic RPC protocol

This patch fixes the compilation of netlink.c and interface.c on those systems missing either libnl or that have an older linux/if_link.h include file not supporting macvtap or VF_PORTS. WITH_MACVTAP is '1' if newer include files were detected, '0' otherwise. IFLA_PORT_MAX is defined in linux/if_link.h if yet more functionality is supported.

POSIX allows implementations where PATH_MAX is undefined, leading to compilation error. Not to mention that even if it is defined, it is often wasteful in relation to the amount of data being stored.

In a second cleanup step this patch makes several interface functions from macvtap.c commonly available by moving them into interface.c and prefixing their names with 'iface'. Those functions taking Linux-specific structures as parameters are only visible on Linux. ifaceRestoreMacAddress returns the return code from the ifaceSetMacAddr call and display an error message if setting the MAC address did not work. The caller is unchanged and still ignores the return code (which is ok).
