The qemu_bridge_filter.c file had some helpers for calling
the ebtablesXXX functions todo bridge filtering. The only
thing these helpers did was to overwrite the original error
message from the ebtables code. For added fun, the callers
of these helpers overwrote the errors yet again. For even
more fun, one of the helpers called another helper and
overwrite its errors too.

GNULIB provides APIs for calculating md5 and sha256 hashes,
but these APIs only return you raw byte arrays. Most users
in libvirt want the hash in printable string format. Add
some helper APIs in util/vircrypto.{c,h} for doing this.

Systemd does not forget about the cases, where client service needs to
wait for daemon service to initialize and start accepting new clients.
Setting a dependency in client is not enough as systemd doesn't know
when the daemon has initialized itself and started accepting new
clients. However, it offers a mechanism to solve this. The daemon needs
to call a special systemd function by which the daemon tells "I'm ready
to accept new clients". This is exactly what we need with
libvirtd-guests (client) and libvirtd (daemon). So now, with this
change, libvirt-guests.service is invoked not any sooner than
libvirtd.service calls the systemd notify function.

This function aims at converting LXC configuration into a libvirt
domain XML description to help users migrate from LXC to libvirt.
Here is an example of how the lxc configuration works:
virsh -c lxc:/// domxml-from-native lxc-tools /var/lib/lxc/migrate_test/config
It is possible that some parts couldn't be properly mapped into a
domain XML fragment, so users should carefully review the result
before creating the domain.
fstab files in lxc.mount lines will need to be merged into the
configuration file as lxc.mount.entry.
As we can't know the amount of memory of the host, we have to set a
default value for max_balloon that users will probably want to adjust.

Bugs have been found in the VirtualBox API C bindings. These bugs have
been fixed in versions 4.2.20 and 4.3.4. However, the changes in the
C bindings are incompatible with the vbox_CAPI_v4_2.h and vbox_CAPI_v4_3.h
files which are bundled in libvirt source code.
This is why the following patch adds vbox_CAPI_v4_2_20.h and
vbox_CAPI_v4_3_4.h.
The actual underlying problem here is that until now,
libvirt assumed that VirtualBox API can only change between minor
versions (4.2 -> 4.3), but we have a case here where it changed
(or got fixed) between patch versions (4.2.18 -> 4.2.20).
This patch makes the VBOX_API_VERSION represent the full API
version number (i.e 4002 => 4002000) so there are specific version
numbers for Vbox 4.2.20 (4002020) and 4.3.4 (4003004)
I noticed this problem when adding systemd support to netcf, because I
setup the configure.ac to automatically prefer using systemd over
initscripts when possible - although I had copied the
install-data-local target from the example of libvirt's
"libvirt-guests" service more or less verbatim, "make distcheck" would
fail because it was trying to install the service file directly into
/lib/systemd/system rather than into
/home/user/some/unimportant/name/lib/systemd/system.
This is caused by the install/uninstall rules for the systemd unit
files relying on $(DESTDIR) pointing the installed files to the right
place, but in reality $(DESTDIR) is empty during this part of make
distcheck - it instead sets $(prefix) with the toplevel directory used
for its test build/install/uninstall cycle.
(This problem hasn't been seen when running "make distcheck" in
libvirt because libvirt will never build/install systemd support
unless explicitly told to do so on the configure commandline, and
"make distcheck" doesn't put the "--with-initscript=..." option on the
configure commandline.)
I verified that the same problem does exist in libvirt by modifying
libvirt's configure.ac to set:
init_systemd=yes
with_init_script=systemd+redhat
This forces a build/install of the systemd unit files during
distcheck, which yields an error like this:
/usr/bin/install -c -m 644 virtlockd.service \
/lib/systemd/system/
libtool: install: warning: relinking `libvirt-qemu.la'
/usr/bin/install: cannot remove '/lib/systemd/system/virtlockd.service': Permission denied
make[4]: *** [install-systemd] Error 1
After adding $(prefix) to all the definitions of SYSTEMD_UNIT_DIR,
make distcheck now completes successfully with the modified
configure.ac, and the above lines change to something like this:
/usr/bin/install -c -m 644 virtlockd.service \
/home/laine/devel/libvirt/libvirt-1.2.1/_inst/lib/systemd/system/
Define the public API for (de-)registering network events
and the callbacks for receiving lifecycle events. The lifecycle
event includes a 'detail' parameter to match the domain lifecycle
event data, but this is currently unused.
The network events related code goes into its own set of internal
files src/conf/network_event.[ch]
We support gluster volumes in domain XML, so we also ought to
support them as a storage pool. Besides, a future patch will
want to take advantage of libgfapi to handle the case of a
gluster device holding qcow2 rather than raw storage, and for
that to work, we need a storage backend that can read gluster
storage volume contents. This sets up the framework.
Note that the new pool is named 'gluster' to match a
<disk type='network'><source protocol='gluster'> image source
already supported in a <domain>; it does NOT match the
<pool type='netfs'><source><target type='glusterfs'>,
since that uses a FUSE mount to a local file name rather than
a network name.
This and subsequent patches have been tested against glusterfs
3.4.1 (available on Fedora 19); there are likely bugs in older
versions that may prevent decent use of gfapi, so this patch
enforces the minimum version tested. A future patch may lower
the minimum. On the other hand, I hit at least two bugs in
3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth
raising the minimum: glfs_readdir is nicer to use than
glfs_readdir_r [1], and glfs_fini should only return failure on
an actual failure [2].

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.

The LXC controller uses dbus to talk to systemd to create
cgroups. This means that each LXC controller instance has
a dbus connection. The DBus daemon is limited to 256
connections by default and we want to be able to run many
1000 of containers.
While the dbus limit could be raised in the config files,
it is simpler to make libvirt LXC controller close its
dbus connection once everything is configured.

I tried to test ./configure --without-lxc --without-remote.
First, the build failed with some odd errors, such as an
inability to build xen, or link failures for virNetTLSInit.
But when you think about it, once there is no remote code,
all of libvirtd is useless, any stateful driver that depends
on libvirtd is also not worth compiling, and any libraries
used only by RPC code are not needed. So I patched
configure.ac to make for some saner defaults when an
explicit disable is attempted. Similarly, since we have
migrated virnetdevbridge into generic code, the workaround
for Linux kernel stupidity must not depend on stateful
drivers being in use.
Then there's 'make check' that needs segregation.
Wow - quite a bit of cleanup to make --without-remote useful :)

drivers and other libraries. Pick up Linux kernel workarounds

This splits up the version parsing code into a callable API like QEMU
help/version string parsing so that we can test it as we need to add
additional patterns for newer versions/products.
Commit 073e1575 tried to set things up so that 1) generated files
to be shipped in the tarball always live in srcdir, and 2) we have
no files in SOURCES that depend on any other files with a literal
$(srcdir) in the name, because that situation can cause confusing
results for the make expansion of $@ depending on whether the file
is found locally or via VPATH. But all my testing for that patch
was done incrementally, where all the protocol.[ch] files had
already been generated prior to the patch and were up-to-date in
the srcdir, and thus I missed one case where $@ causes grief in a
VPATH build from a fresh checkout:
We have a pattern rule for generating remote_protocol.[ch], and
what's more, the rule for protocol.c depends on protocol.h AND
on the protocol.x file. The pattern for protocol.c is only
satisfied via the VPATH lookup for protocol.x, and if protocol.h
doesn't yet exist, the VPATH rule kicks in and we end up with a
dependency on a file with $(srcdir) in the name. Based on make's
rules for $@, this resulted in make building remote_protocol.h
into srcdir (where we want it), then remote_protocol.c into
builddir (oops, not so good for the tarball), and also causes
the build to fail (the compiler can't find the .h if it lives
in a different directory than the .c):
CC remote/libvirt_driver_remote_la-remote_protocol.lo
remote/remote_protocol.c:7:29: fatal error: remote_protocol.h: No such file or directory
#include "remote_protocol.h"
^
compilation terminated.
As before, the fix is to hard-code the output file to go into
srcdir in spite of $@; but since this is in a pattern rule, we
are forced to use $@ in the recipe, so the patch is a bit
trickier than what was done in commit 073e1575.

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 $@.

are performed for each API, this patch extends the API docs
generator to include details of the ACLs for each.
The gendispatch.pl script is extended so that it generates
a simple XML describing ACL rules, eg.
<aclinfo>
...
<api name='virConnectNumOfDomains'>
<check object='connect' perm='search_domains'/>
<filter object='domain' perm='getattr'/>
</api>
<api name='virDomainAttachDeviceFlags'>
<check object='domain' perm='write'/>
<check object='domain' perm='save' flags='!VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE'/>
<check object='domain' perm='save' flags='VIR_DOMAIN_AFFECT_CONFIG'/>
</api>
...
</aclinfo>
The newapi.xsl template loads the XML files containing the ACL
rules and generates a short block of HTML for each API describing
the parameter checks and return value filters (if any).

On a mingw VPATH build (such as done by ./autobuild.sh), the tarball
created by 'make dist' was including generated files. The VPATH

not regenerating files locally, leading to this failure:

intentionally not part of the tarball; stick the access sym
files in that category. The rearrange the declarations a bit

Extend the 'gendispatch.pl' script to be able to generate
three new types of file.
- 'aclheader' - defines signatures of helper APIs for
doing authorization checks. There is one helper API
for each API requiring an auth check. Any @acl
annotations result in a method being generated with
a suffix of 'EnsureACL'. If the ACL check requires
examination of flags, an extra 'flags' param will be
present. Some examples
extern int virConnectBaselineCPUEnsureACL(void);
extern int virConnectDomainEventDeregisterEnsureACL(virDomainDefPtr domain);
extern int virDomainAttachDeviceFlagsEnsureACL(virDomainDefPtr domain, unsigned int flags);
Any @aclfilter annotations resuilt in a method being
generated with a suffix of 'CheckACL'.
extern int virConnectListAllDomainsCheckACL(virDomainDefPtr domain);
These are used for filtering individual objects from APIs
which return a list of objects
- 'aclbody' - defines the actual implementation of the
methods described above. This calls into the access
manager APIs. A complex example:
/* Returns: -1 on error (denied==error), 0 on allowed */
int virDomainAttachDeviceFlagsEnsureACL(virConnectPtr conn,
virDomainDefPtr domain,
unsigned int flags)
{
virAccessManagerPtr mgr;
int rv;
if (!(mgr = virAccessManagerGetDefault()))
return -1;
if ((rv = virAccessManagerCheckDomain(mgr,
conn->driver->name,
domain,
VIR_ACCESS_PERM_DOMAIN_WRITE)) <= 0) {
virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
if (((flags & (VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE)) == 0) &&
(rv = virAccessManagerCheckDomain(mgr,
conn->driver->name,
domain,
VIR_ACCESS_PERM_DOMAIN_SAVE)) <= 0) {
virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
if (((flags & (VIR_DOMAIN_AFFECT_CONFIG)) == (VIR_DOMAIN_AFFECT_CONFIG)) &&
(rv = virAccessManagerCheckDomain(mgr,

virObjectUnref(mgr);
if (rv == 0)
virReportError(VIR_ERR_ACCESS_DENIED, NULL);
return -1;
}
virObjectUnref(mgr);
return 0;
}
- 'aclsyms' - generates a linker script to export the
APIs to drivers. Some examples
virConnectBaselineCPUEnsureACL;
virConnectCompareCPUEnsureACL;

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

A few things have changed in the VirtualBox API - some small
(capitalizations of things in function names like Ip to IP
and Dhcp to DHCP) and some much larger (FindMedium is superceded
by OpenMedium). The biggest change for the sake of this patch
is the signature of CreateMachine is quite a bit different. Using
the Oracle source as a guide, to spin up a VM with a given UUID,
it looks like a text flag has to be passed in a new argument to
CreateMachine. This flag is built in the VirtualBox 4.2 specific
ifdefs and is kind of ugly but works. Additionally, there is now
(unused) VM groups support in CreateMachine and the previous
'osTypeId' arg is currently set to nsnull as in the Oracle code.
The FindMedium to OpenMedium changes were more straightforward
and are pretty clear. The rest of the vbox template changes are
basically spelling/capitalization changes from the looks of things.

By default, libtool builds two .o files for every .lo rule:
src/foo.o - static builds
src/.libs/foo.o - shared library builds
But since commit ad42b34b disabled static builds, src/foo.o is
no longer built by default. On a fresh checkout, this means our
protocol check rules using pdwtags were testing a missing file,
and thanks to a lousy behavior of pdwtags happily giving no output
and 0 exit status (http://bugzilla.redhat.com/949034), we were
merely claiming that "dwarves is too old" and skipping the test.
However, if you swap between branches and do incremental builds,
such as building v0.10.2-maint and then switching back to master,
you end up with src/foo.o being leftover from its 0.10.2 state,
and then 'make check' fails because the .o file does not match
the protocol-structs file due to API additions in the meantime.
A simpler fix would be to always look in .libs for the .o to
be parsed; but since it is possible to pass ./configure options
to tell libtool to do a static-only build with no shared .o,
I went with the approach of finding the newest of the two files,
whenever both exist.

The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser

This patch aims to create a new data structure virDomainXMLConf that

allow two things we need:
1) Get rid of the stuff from virCaps
2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

virCommand gets two new APIs: virCommandSetSELinuxLabel() and
virCommandSetAppArmorProfile(), which both save a copy of a
null-terminated string in the virCommand. During virCommandRun, if the
string is non-NULL and we've been compiled with AppArmor and/or
SELinux security driver support, the appropriate security library
function is called for the child process, using the string that was
previously set. In the case of SELinux, setexeccon_raw() is called,
and for AppArmor, aa_change_profile() is called.
This functionality has been added so that users of virCommand can use
the upcoming virSecurityManagerSetChildProcessLabel() prior to running
a child process, rather than needing to setup a hook function to be
called (and in turn call virSecurityManagerSetProcessLabel()) *during*
the setup of the child process.
This makes it simpler to include the necessary system security driver
libraries for a particular system. For this patch, several existing
conditional sections from the Makfile were replaced; I'll later be
adding SECDRIVER_LIBS to libvirt_util_la_LIBADD, because vircommand.c
will be calling a function from $securitylib.
We have several cases where we need to read endian-dependent
data regardless of host endianness; rather than open-coding
these call sites, it will be nicer to funnel things through

libvirt.c calls curl_global_init() if WITH_CURL is defined and thus it

CURL_{CFLAGS,LIBS}, and a part of curl check was left in
configure.ac instead of m4/virt-curl.m4 by mistake
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.
