GCC complained about a C99 for-loop declaration outside of C99 mode
when compiling on RHEL 5.
* src/qemu/qemu_driver.c (qemudDomainPinVcpuFlags): Avoid C99 for
loop, since gcc 4.1.2 hates it.
This patch adds documentation about the 802.1Qbh related parameters
of the virtualport element for 'direct' interfaces.

Gnulib has been busy, with 397 commits; it's easier to update now
even without any known libvirt issue to be fixed, rather than
having to analyze an even larger changeset later on.
* .gnulib: Update to latest, for lots of changes.
* bootstrap: Synchronize to upstream.
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.
Turns out I was right in removing this the first time :) This is
needed in our custom __del__ function, but the C code wasn't
being generated. Add new infrastructure to do what we want
volDelete used to return VIR_ERR_INTERNAL_ERROR when attempting to
delete a volume which was still being allocated. It should return
VIR_ERR_OPERATION_INVALID.
* src/storage/storage_driver.c: Fix return of volDelete.
See previous patch for why this is good...
* src/xen/xen_driver.h (xenXMConfCache): Manage filename
dynamically.
* src/xen/xm_internal.c (xenXMConfigCacheAddFile)
(xenXMConfigFree, xenXMDomainDefineXML): Likewise.
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.
All clients of vol->key were audited, and found not to care about
whether key is static or dynamic, except for these offenders:
* src/datatypes.h (struct _virStorageVol): Manage key dynamically.
* src/datatypes.c (virReleaseStorageVol): Free key.
(virGetStorageVol): Copy key.
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).
In a first cleanup step, make nlComm from macvtap.c commonly available
for other code to use. Since nlComm uses Linux-specific structures as
parameters it's prototype is only visible on Linux.
We weren't using the @FOO@ notation for a Makefile substitution,
but instead for a sed rule, so using [@]FOO@ instead avoids the
need to exempt this syntax check.
* cfg.mk (_makefile_at_at_check_exceptions): Delete.
* tools/Makefile.am (virt-xml-validate, virt-pki-validate): Avoid
tripping syntax-check.

Files under src/util must not depend on src/conf
Solve the macvtap problem by moving the definition
of macvtap modes from domain_conf.h into macvtap.h
* src/util/macvtap.c, src/util/macvtap.h: Add enum
for macvtap modes
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove
enum for macvtap modes
This fixes a number of issues most of them raised by Eric Blake on the
generated documentation output:
- parsing of "long long int" and similar
- add parsing of unions within a struct
- remove spurious " * " fron comments on structure fields and enums
- fix concatenation of base type and name in arrays
- extend XSLT to cope with union in structs
* docs/apibuild.py: fix and extend API extraction tool
* docs/newapi.xsl: extend the stylesheets to cope with union in
public structures
For virtio disks and interfaces, qemu allows users to enable or disable
ioeventfd feature. This means, qemu can execute domain code, while
another thread waits for I/O event. Basically, in some cases it is win,
in some loss. This feature is available via 'ioeventfd' attribute in disk
and interface <driver> element. It accepts 'on' and 'off'. Leaving this
attribute out defaults to hypervisor decision.
When building rpms for newer Fedora or RHEL, take advantage of the
newer netcf packaging to guarantee interface snapshot support.
* libvirt.spec.in (BuildRequires): Bump minimum version on
platforms that support netcf 0.1.8.
https://bugzilla.redhat.com/show_bug.cgi?id=682121
Gettext reserves the empty string for internal use, and it must
not be passed through _(). We were violating this for commands
that (for whatever reason) used "" for their description.
* tools/virsh.c (vshCmddefHelp): Don't translate empty string.

The following patch addresses the problem that when a PASSTHROUGH
mode DIRECT NIC connection is made the MAC address of the NIC is
not automatically set and reset to the configured VM MAC and
back again.
The attached patch fixes this problem by setting and resetting the MAC
while remembering the previous setting while the VM is running.
This also works if libvirtd is restarted while the VM is running.
the patch passes make syntax-check
These functions aren't intended to be called directly by users, so mark
them as private.
While we're at it, remove unneeded exception handling, and break some
long lines.
If registering our own event loop implementation written in python,
any handles or timeouts callbacks registered by libvirt C code must
be wrapped in a python function. There is some argument trickery that
makes this all work, by wrapping the user passed opaque value in
a tuple, along with the callback function.
Problem is, the current setup requires the user's event loop to know
about this trickery, rather than just treating the opaque value
as truly opaque.
Fix this in a backwards compatible manner, and adjust the example
python event loop to do things the proper way.
Since we virEventRegisterDefaultImpl is now a public API, callers need
a way to invoke the default registered Handle and Timeout functions. We
already have general functions for these internally, so promote
them to the public API.
v2:
Actually add APIs to libvirt.h
Pure python implementation. The handler callbacks have been altered
a bit compared to the C API: RecvAll doesn't pass length of the data read
since that can be trivially obtained from python string objects, and SendAll
requires the handler to return the string data to send rather than
store the data in a string pointer.
The return values for the python version are different that the C version
of virStreamSend: on success we return a string, an error raises an exception,
and if the stream would block we return int(-2). We need to do this
since strings aren't passed by reference in python.
* virDomainDefParse: There is a goto label "no_memory", which
reports OOM error, and then fallthrough label "error". This
patch changes things like following:
virReportOOMError();
goto error;
into:
goto no_memory;
Producing an xml file just for name and description fields is
overkill; this makes life easier from virsh.
* tools/virsh.c (cmdSnapshotCreateAs): New command.
(snapshotCmds): Install it.
* tools/virsh.pod: Document it.
The 'char *cur' variable was being assigned from a
'const char *' string, thus discarding constness.
As well as causing a compile warning, it masked a
piece of code which attempts to assign to the
previously const string.
* tools/virsh.c: Fix const-ness of 'cur' variable in vcpupin
Removes special case code from the generator and handle additional
methods.
The generated version of remoteDispatchDomainPinVcpu(Flags) has no
length check, but this check was useless anyway as it was applied to
data that was already deserialized from its XDR form.
Pinning to all physical cpus means resetting, hence it is preferable to
delete vcpupin setting of XML.
This patch changes qemu driver to delete vcpupin setting by invoking
virDomainVcpupinDel API when pinning the specified virtual cpu to
all host physical cpus.
