This patch adds common code to list domains in fashion used by
virListAllDomains with all currently supported flags. The header file
also contains macros that group filters together that are used to
shorten filter conditions.
'make dist' was depending on *protocol-structs files, which are
stored in git but in turn depended on generated files. We still
want to ship the protocol-structs files, but by renaming the
tests to something not matching a file name, we separate 'make
check' (which depends on the generated file) from 'make dist'
(which only depends on the git files). After all, the tarball
should never depend on a generated file not stored in git.
I found one more case of a git file depending on a generated
file, in a bogus virkeycode.c listing; but at least this one
had no associated rules so it never broke 'make dist'.
Reported by Wen Congyang. Latent bug has been present since
commit 62dee6f, but only recently exposed by commit 7bff56a.

Commit 7bff56a worked in an incremental build, but fails for a

spelling and an inference rule, only the exact spelling is used.

Commit 1c275e9a accidentally dropped the storage driver from
libvirtd, because it depended on a C preprocessor macro that
was not defined. Furthermore, if you do './configure
--without-storage-dir --with-storage-disk' or any other combination
where you explicitly build a subset of storage backends excluding
the dir backend, then the build is broken.

We had a distributed file (remote_protocol.h, which in turn was
a prereq to remote_driver.c) depending on a generated file

that situation):

Rather than making distributed .c files depend on generated files, we
really want to ensure that compilation into .lo files is not attempted
until the generated files are present, done by this patch. Since there
were two different sets of conditionally generated files that both
feed the .lo file, I had to introduce a new variable REMOTE_DRIVER_PREREQS
to keep automake happy.
After that fix, the next issue was that make treats './foo' and 'foo'
differently in determining whether an implicit %foo rule is applicable,
with the result that locking/qemu-sanlock.conf wasn't properly being
built at the right times. Also, the output for using the .aug test
files was a bit verbose.
After fixing the src directory, the next error is related to the docs
directory, where the tarball is missing a stamp file and thus tries to
regenerate files that are already present:
GEN ../../docs/apibuild.py.stamp

Although src/util/viratomic.h has been added to the repo, up until now
it hasn't been used. Stefan Berger is using it in his proposed dhcp
snooping patches, and an rpm build with those patches failed due to
viratomic.h not being packed up with the rest of the sources.
The goal of this patch is to prepare for support for multiple IP
addresses per interface in the DHCP snooping code.
Move the code for the IP address map that maps interface names to
IP addresses into their own file. Rename the functions on the way
but otherwise leave the code as-is. Initialize this new layer
separately before dependent layers (iplearning, dhcpsnooping)
and shut it down after them.
This patch adds DHCP snooping support to libvirt. The learning method for
IP addresses is specified by setting the "CTRL_IP_LEARNING" variable to one of
"any" [default] (existing IP learning code), "none" (static only addresses)
or "dhcp" (DHCP snooping).
Active leases are saved in a lease file and reloaded on restart or HUP.
The following interface XML activates and uses the DHCP snooping:
<interface type='bridge'>
<source bridge='virbr0'/>
<filterref filter='clean-traffic'>
<parameter name='CTRL_IP_LEARNING' value='dhcp'/>
</filterref>
</interface>
All filters containing the variable 'IP' are automatically adjusted when
the VM receives an IP address via DHCP. However, multiple IP addresses per
interface are silently ignored in this patch, thus only supporting one IP
address per interface. Multiple IP address support is added in a later
patch in this series.

Apart from the non-sanlock check build, there is also a little fix for
qemu (EXTRA_DIST had qemu.conf and others inside even if the build was
supposed to be without qemu).
Some of our rules used $(PERL), while others used 'perl'. Always
using the variable allows a developer to point to a different (often
better) perl than the default one found on $PATH.

cannot read libvirtd.conf: No such file or directory at ../../build-aux/augeas-gentest.pl line 38.
Since the test files are not part of the tarball, we can generate
them into the build dir, but rather than create a subdirectory
just for the test file, it is easier to test them directly in
libvirt.git/src.

I added libvirt_qemu_probes.h into BUILT_SOURCES. That makes it
generated, but most probably it is not the clearest way how to do
that, but it fixes the build.
The previous patch fixed an incremental build, but missed that on
a fresh checkout, we now have nothing left that stops make from
nuking libvirt_qemu_probes.o.

since this variable is empty.
(.PRECIOUS): Add %_probes.o, so they don't get nuked as an
intermediate by-product after creating %_probes.lo.
The moment you specify a _DEPENDENCIES, older automake (stupidly)
assumes that you will specify _all_ dependencies for that target.
This stupidity has been fixed in automake 1.12, but we cannot rely on
newer automake everywhere. For libvirt_la_DEPENDENCIES, we took
care of providing the full list, but for libvirt_qemu_la_DEPENDENCIES,
we were missing the dependency on libvirt_qemu_impl.la, which resulted
in a failed build:

There was no rule forcing libvirt_qemu_probes.o to be built
before libvirt_qemu_probes.lo was used. Also libvirtd was
still referencing the .o file, rather than the .lo file.
Both the .lo and .o file must be listed as DEPENDENCIES,
otherwise libtool will unhelpfully delete the .o file
once the .lo file is created.

Libtool supports linking directly against .o files on some platforms

actually doing that (for the dtrace-generated probes.o files). However,

attempt it on platforms where it would actually fail:

When building as driver modules, it is not possible for the QEMU

The driver modules all use symbols which are defined in libvirt.so.
Thus for loading of modules to work, the binary that libvirt.so
is linked to must export its symbols back to modules. If the
libvirt.so itself is dlopen()d then the RTLD_GLOBAL flag must
be set. Unfortunately few, if any, programming languages use
the RTLD_GLOBAL flag when loading modules :-( This means is it
not practical to use driver modules for any libvirt client side
drivers (OpenVZ, VMWare, Hyper-V, Remote client, test).
This patch changes the build process so only server side drivers
are built as modules (Xen, QEMU, LXC, UML)

This patch adds support for a new storage backend with RBD support.
RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.
It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.
To function this backend relies on librbd and librados being present on the
local system.
The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.
For storing credentials it uses the built-in secret mechanism of libvirt.

the DBus connection is integrated with the event loop and
provides such glue logic itself.
The forthcoming FirewallD integration also requires a

Thus we create src/util/virdbus.{c,h} files. This contains
just one method virDBusGetSystemBus() which obtains a handle

This patch adds a set of functions used in creating console streams for
domains using PTYs and ensures mutually exclusive access to the PTYs.
If mutually exclusive access is not used, two clients may open the same
console, which results in corruption on both clients as both of them
race to read data from the PTY.
Two approaches are used to ensure this:
1) Internal data structure holding open PTYs.
This is used internally and enables the user to forcibly
terminate another console connection eg. when somebody leaves
the console open on another host.
2) UUCP style lock files:
This uses UUCP lock files according to the FHS
( http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES )
to check if other programs (like minicom) are not using the pty
device of the console.
This feature is disabled by default and may be enabled using
configure parameter
--with-console-lock-files=/path/to/lock/file/directory
or --with-console-lock-files=auto (which tries to infer the
location from OS used (currently only linux).
On usual linux systems, normal users may not write to the
/var/lock directory containing the locks. This poses problems
while in session mode. If the current user has no access to the
lockfile directory, check for presence of the file is still
done, but no lock file is created. This does NOT result in an
error.
Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.

- src/util/viruri.h -- declaration
- src/util/viruri.c -- definition
- src/libvirt_private.syms -- symbol export

The /usr/include/python/pyconfig.h file pollutes the global
namespace with a huge number of HAVE_XXX and WITH_XXX
defines. These change what we detected in our own config.h
In particular if you try to build without DTrace, python's
headers turn it back on with predictable fail.
THe hack to workaround this is to rename WITH_DTRACE to
WITH_DTRACE_PROBES to avoid the namespace clash
This patch allows libvirt to add interfaces to already
existing Open vSwitch bridges. The following syntax in

<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
or if libvirt should auto-generate the interfaceid use
following syntax:
<interface type='bridge'>
<mac address='52:54:00:d0:3f:f2'/>
<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
It is also possible to pass an optional profileid. To do that
use following syntax:
<interface type='bridge'>
<source bridge='ovsbr'/>
<mac address='00:55:1a:65:a2:8d'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'

Recent discussions have illustrated the potential for DOS attacks
with the hash table implementations used by most languages and
libraries.
https://lwn.net/Articles/474912/
libvirt has an internal hash table impl, and uses hash tables for
a variety of purposes. The hash key generation code is pretty
simple and thus not strongly collision resistant.
This patch replaces the current libvirt hash key generator with
the (public domain) Murmurhash3 code. In addition every hash
table now gets a random seed value which is used to perturb the
hashing code. This should make it impossible to mount any
practical attack against libvirt hashing code.
