497adba2d4 Expand virSocketFormat to be more flexible
The getnameinfo() function is more flexible than inet_ntop()
avoiding the need to if/else the code based on socket family.
Also make it support UNIX socket addrs and allow inclusion
of a port (service) address. Finally do proper error reporting
via normal APIs.

* src/conf/domain_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c,
  src/qemu/qemu_conf.c: Fix error handling with virSocketFormat
* src/util/network.c: Rewrite virSocketFormat to use getnameinfo
  and cope with UNIX socket addrs.

7ab7d17bfb Remove pointless nwIPAddress struct & void *casts
The nwIPAddress was simply a wrapper about virSocketAddr.
Just use the latter directly, removing all the extra field
de-references from code & helper APIs for parsing/formatting.

Also remove all the redundant casts from strong types to
void * and then immediately back to strong types.

* src/conf/nwfilter_conf.h: Remove nwIPAddress
* src/conf/nwfilter_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c:
  Update to use virSocketAddr and remove void * casts.

746c336495 Fix passing of address family to virSocketParseAddr
The virSocketParseAddr function was accepting any AF_* constant
and using that to set the ai_flags field in struct addrinfo.
This is invalid, since address families must go in the ai_family
field of the struct.

* src/util/network.c: Fix handling of address family
* src/conf/network_conf.c, src/network/bridge_driver.c: Pass
  AF_UNSPEC instead of relying on it being 0.

af3d4eec0d Include length with virSocketAddr data
Some operations on socket addresses need to know the length of
the sockaddr struct for the particular address family. This
info was being discarded when passing around virSocketAddr
instances. Turn it from a union into a struct containing
union+socklen_t fields, so length is always kept around.

* src/util/network.h: Add socklen_t field to virSocketAddr
* src/util/network.c, src/network/bridge_driver.c,
  src/conf/domain_conf.c: Update to take account of new
  struct definition.

9e42b40a95 Remove useless code in error path of getnameinfo()
If getnameinfo() with NI_NUMERICHOST set fails, there are no
grounds to expect inet_ntop to succeed, since these calls
are functionally equivalent. Remove useless inet_ntop code
in the getnameinfo() error path.

* daemon/remote.c, src/remote/remote_driver.c: Remove
  calls to inet_ntop

9bd3cce0d2 Fix symbol exports & remove duplicated libvirt_util.la linkage
The libvirt_util.la library was mistakenly linked into libvirtd
directly. Since libvirt_util.la is already linked to libvirt.so,
this resulted in libvirtd getting two copies of the code and
more critically 2 copies of static global variables.

Testing in turn exposed a issue with loadable modules. The
gnulib replacement functions are not exported to loadable
modules. Rather than trying to figure out the name sof all
gnulib functions & export them, just linkage all loadable
modules against libgnu.la statically.

* daemon/Makefile.am: Remove linkage of libvirt_util.la
  and libvirt_driver.la
* src/Makefile.am: Link driver modules against libgnu.la
* src/libvirt.c: Don't try to load modules which were

b8e2de8899 Audit SELinux label assignment.
A more natural auditing point would perhaps be
SELinuxSetSecurityProcessLabel, but this happens in the child after root
permissions are dropped, so the kernel would refuse the audit record.

a8b5f9bd27 Audit VM start/stop/suspend/resume
Most operations are audited at the libvirtd level; auditing in
src/libvirt.c would result in two audit entries per operation (one in
the client, one in libvirtd).

The only exception is a domain stopping of its own will (e.g. because
the user clicks on "shutdown" inside the interface).  There can often be
no client connected at the time the domain stops, so libvirtd does not
have any virConnectPtr object on which to attach an event watch.  This
patch therefore adds auditing directly inside the qemu driver (other
drivers are not supported).

8f680ad3b8 Basic framework for auditing integration
Integrate with libaudit.so for auditing of important operations.
libvirtd gains a couple of config entries for auditing. By
default it will enable auditing, if its enabled on the host.
It can be configured to force exit if auditing is disabled
on the host. It will can also send audit messages via libvirt
internal logging API

Places requiring audit reporting can use the VIR_AUDIT
macro to report data. This is a no-op unless auditing is
enabled

  on mingw
* configure.ac: Add check for libaudit

0fab10e5ed vcpu: improve vcpu support in xen command line
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3

See this link for more details about vcpu_avail for xm usage.
http://lists.xensource.com/archives/html/xen-devel/2009-11/msg01061.html

This relies on the fact that def->maxvcpus can be at most 32 with xen.

Although this patch adds a distinction between maximum vcpus and

50c51f13e2 vcpu: make old API trivially wrap to new API

function identically, since the new API validates that the exact

the full range of flag support in the new API.

f04de501bc Introduce VIR_CLOSE to be used rather than close()
Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here.

There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were.

I also dare to declare close() as being deprecated in libvirt code base (HACKING).

b2c9a87940 root_squash: virFileOperation may fail with EPERM too
Over root-squashing nfs, when virFileOperation() is called as uid==0,
it may fail with EACCES, but also with EPERM, due to
virFileOperationNoFork()'s failed attemp to chown a writable file.

qemudDomainSaveFlag() should expect this case, too.

b7bd75c4c0 Run initgroups() in qemudOpenAsUID()
qemudOpenAsUID is intended to open a file with the credentials of a
specified uid. Current implementation fails if the file is accessible to
one of uid's groups but not owned by uid.

This patch replaces the supplementary group list that the child process
inherited from libvirtd with the default group list of uid.
