8d9d098b6d event: wire up RPC for server-side network event filtering
We haven't had a release with network events yet, so we are free
to fix the RPC so that it actually does what we want.  Doing
client-side filtering of per-network events is inefficient if a
connection is only interested in events on a single network out
of hundreds available on the server.  But to do server-side
per-network filtering, the server needs to know which network
to filter on - so we need to pass an optional network over on
registration.  Furthermore, it is possible to have a client with
both a global and per-network filter; in the existing code, the
server sends only one event and the client replicates to both
callbacks.  But with server-side filtering, the server will send
the event twice, so we need a way for the client to know which
callbackID is sending an event, to ensure that the client can
filter out events from a registration that does not match the
callbackID from the server.  Likewise, the existing style of
deregistering by eventID alone is fine; but in the new style,
we have to remember which callbackID to delete.

This patch fixes the RPC wire definition to contain all the
needed pieces of information, and hooks into the server and
client side improvements of the previous patches, in order to
switch over to full server-side filtering of network events.
Also, since we fixed this in time, all released versions of
libvirtd that support network events also support per-network
filtering, so we can hard-code that assumption into
network_event.c.

Converting domain events to server-side filtering will require
the introduction of new RPC numbers, as well as a server
feature bit that the client can use to tell whether to use
old-style (server only supports global events) or new-style
(server supports filtered events), so that is deferred to a
later set of patches.

Assume server-side filtering.

b9d14ef03b event: track callbackID on daemon side of RPC
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.
(remoteEventCallbackFree): New function.
(remoteClientInitHook, remoteRelayNetworkEventLifecycle)

(remoteDispatchConnectNetworkEventRegisterAny): Track network
callbacks differently.
(remoteDispatchConnectNetworkEventDeregisterAny): Enforce bounds.

59d6e65d6c virtlockd: improve initscripts
- Use SIGUSR1, not SIGHUP, on reload. At present, virtlockd only
  responds to the former.

- Fix PID file for virtlockd.

- Do not start virtlockd in any runlevels by default. It needs to be
  explicitly selected in libvirt's qemu.conf anyway, so there is no
  need to have it running on all systems regardless.

- Fix chkconfig priorities to ensure virtlockd is started before
  libvirtd is started, and stopped after libvirtd is stopped.

- Add "Should-Start: virtlockd" to the libvirtd initscript's LSB header,
  for the same reason.

- Add "Default-Stop" to both libvirtd and virtlockd initscripts. LSB
  does not guarantee that this defaults to the inverse of
  "Default-Start".

a602e90bc1 daemon: Run virStateCleanup conditionally
https://bugzilla.redhat.com/show_bug.cgi?id=1033061

Currently, initialization of drivers is done in a separate thread. This
is done for several reasons: a driver that is initialized may require
running event loop, it may take ages to initialize driver (e.g. due to
autostarting domains). While the thread is spawn and run, the main()
continues its execution. However, if something goes bad, or the event
loop is just exited (e.g. due to a --timeout or SIGINT) we try to
cleanup all the drivers. So we have two threads running Initialize() and
Cleanup() concurrently. This may result in accessing stale pointers -
e.g. netcf driver will free() itself in stateCleanup callback, while the
init thread may come, open a dummy connection in order to autostart some
domains and voilà: do_open() iterates over interface drivers and
accesses stale netcf driver.

The fix consists in not running stateCleanup if the init thread is still
running.

3e2f27e13b Don't link virt-login-shell against libvirt.so (CVE-2013-4400)
The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.

The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.

Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

8294aa0c17 Fix crash in libvirtd when events are registered & ACLs active
When a client disconnects from libvirtd, all event callbacks
must be removed. This involves running the public API

  virConnectDomainEventDeregisterAny

This code does not run in normal API dispatch context, so no
identity was set. The result was that the access control drivers
denied the attempt to deregister callbacks. The callbacks thus
continued to trigger after the client was free'd causing fairly
predictable use of free memory & a crash.

This can be triggered by any client with readonly access when
the ACL drivers are active.

e7f400a110 Fix crash in remoteDispatchDomainMemoryStats (CVE-2013-4296)
The 'stats' variable was not initialized to NULL, so if some
early validation of the RPC call fails, it is possible to jump
to the 'cleanup' label and VIR_FREE an uninitialized pointer.
This is a security flaw, since the API can be called from a
readonly connection which can trigger the validation checks.

922b7fda77 Add support for using 3-arg pkcheck syntax for process (CVE-2013-4311)
With the existing pkcheck (pid, start time) tuple for identifying
the process, there is a race condition, where a process can make
a libvirt RPC call and in another thread exec a setuid application,
causing it to change to effective UID 0. This in turn causes polkit
to do its permission check based on the wrong UID.

To address this, libvirt must get the UID the caller had at time
of connect() (from SO_PEERCRED) and pass a (pid, start time, uid)
triple to the pkcheck program.

This fix requires that libvirt is re-built against a version of
polkit that has the fix for its CVE-2013-4288, so that libvirt
can see 'pkg-config --variable pkcheck_supports_uid polkit-gobject-1'

012c25e88c build: use library rather than cross-directory compilation
If we use subdir-objects with automake, any reference to a
cross-directory .c file will result in automake creating
rules that track dependency in the cross directory.  But this
presents a problem during 'make distclean' - if the cross
directory is cleaned up first, then the daemon directory will
be left with dangling references to .Po dependency files that
no longer exist.

Meanwhile, referring to the cross-directory .c file means
that we are compiling the file twice - once in src, and once
in daemon.  Better is to compile just once in src into a
convenience library, and then use that library from daemon.

The tests directory had a similar situation of a cross-directory
.c file; to solve that, we actually need a convenience library.

* daemon/Makefile.am (DAEMON_SOURCES): Drop .c files...
(libvirtd_LDADD): ...and instead use library.
(libvirtd_conf_la_SOURCES): Declare a new convenience library.

073e157533 build: avoid $(srcdir) in *_SOURCES
Trying to enable automake's subdir-objects option resulted in
the creation of literal directories such as src/$(srcdir)/remote/.
I traced this to the fact that we had used a literal $(srcdir)
in a location that later fed an automake *_SOURCES variable.
This has also been reported as an automake bug:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928
but it's better to fix our code than to wait for an automake fix.

Some things to remember that affect VPATH builds, and where an
in-tree build is blissfully unaware of the issues: if a VPATH
build fails to find a file that was used as a prereq of any
other target, then the rule for that file will expand $@ to
prefer the current build dir (bad because a VPATH build on a
fresh checkout will then stick $@ in the current directory
instead of the desired srcdir); conversely, if a VPATH build
finds the file in srcdir but decides it needs to be rebuilt,
then the rule for that file will expand $@ to include the
directory where it was found out-of-date (bad for an explicit
listing of $(srcdir)/$@ because an incremental VPATH build will
then expand srcdir twice).  As we want these files to go into
srcdir unconditionally, we have to massage or avoid $@ for any
recipe that involves one of these files.

Therefore, this patch removes all uses of $(srcdir) from any
generated file name that later feeds a *_SOURCES variable, and
then rewrites all the recipes to generate those files to
hard-code their creation into srcdir without the use of $@.

* src/Makefile.am (REMOTE_DRIVER_GENERATED): Drop $(srcdir); VPATH
builds know how to find the files, and automake subdir-objects
fails with it in place.

ec81852f46 build: enforce makefile conditional style
Automake has builtin support to prevent botched conditional nesting,

daemon/Makefile.am:381: error: endif reminder (LIBVIRT_INIT_SCRIPT_SYSTEMD_TRUE) incompatible with current conditional: LIBVIRT_INIT_SCRIPT_SYSTEMD_FALSE

As our makefiles tend to have quite a bit of nested conditionals,
it's better to take advantage of the benefits of the build system
double-checking that our conditionals are well-nested, but that
requires a syntax check to enforce our usage style.

Alas, unlike C preprocessor and spec files, we can't use indentation
to make it easier to see how deeply nesting goes.

we should use 'h' as a short option for --help. Also add this to

for the --version arg. Add -V as a valid short option, since
-v is already used for --verbose.

bfd663ef97 Introduce remote protocol support for virDomainCreate{XML}WithFiles
Since they make use of file descriptor passing, the remote protocol
methods for virDomainCreate{XML}WithFiles must be written by hand.

483246f2e1 Convert 'int i' to 'size_t i' in daemon/ files
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

b904bba7f4 Add a policy kit access control driver
Add an access control driver that uses the pkcheck command
to check authorization requests. This is fairly inefficient,
particularly for cases where an API returns a list of objects
and needs to check permission for each object.

It would be desirable to use the polkit API but this links
to glib with abort-on-OOM behaviour, so can't be used. The
other alternative is to speak to dbus directly
