* src/qemu_conf.c (qemudNetworkIfaceConnect):
Suggestion from Daniel P. Berrange.

Also remove a stale comment in the area.  This makes libvirt compile when
passed --with-lxc and --enable-compiler-warnings=error

This gives us the ability to create a veth pair so that we can move one
into the network namespace of an LXC container.

Allow check for containers support to be done without CLONE_NEWNET, and then
determine support on the fly by checking for iproute2 support and a
successful clone(CLONE_NEWNET).  This lets us set a flag for later, as well
as not completely disable LXC support on a system without NETNS support.

fine, except that is subtly alters the semantics of malloc(), calloc(), and
realloc().  In particular, if you say:

foo = malloc(0);

glibc will happily return a non-NULL pointer to you.  However, with the new
memory management stuff, if you say:

foo = VIR_ALLOC(0);

you will actually get a NULL pointer back.  Personally, I think this is a
dangerous deviation from malloc() semantics that everyone is used to, and is
indeed causing problems with the remote driver.  The short of it is that the
remote driver allocates memory on behalf of the remote side using VIR_ALLOC_N,
and this call is returning NULL so that the NULL checks elsewhere in the code
fire and return failure.

The attached patch fixes this situation by removing the 0 checks from the memory
allocation paths, and just lets them fall through to the normal malloc(),
calloc(), or realloc() routines, restoring old semantics.

introduced into the qemudNetworkIfaceConnect() function.  In particular, there
is a call:

    if (VIR_ALLOC_N(vm->tapfds, vm->ntapfds+2) < 0)
        goto no_memory;

However, the tapfds structure is used to track *all* of the tap fds, and is
called once for each network that is being attached to the domain.  VIR_ALLOC_N
maps to calloc().  So the first network would work just fine, but if you had
more than one network, subsequent calls to this function would blow away the
stored fd's that were already there and fill them all in with zeros.  This
causes multiple problems, from the qemu domains not starting properly to
improper cleanup on shutdown.  The attached patch just changes the VIR_ALLOC_N()
to a VIR_REALLOC_N(), and everything is happy again.

to only rely on sysfs for finding LUNs, given a session number.  Along the way,
it also fixes the bug where we wouldn't find LUNs for older kernels (with the
block:sda format), and also fixes a race condition where we could try
to find the LUN before udev has finished connecting it.

This patch fixes a few different bugs:
1) We weren't finding LUNs on pre 2.6.24 kernels
2) libvirtd sysfs scanning was racing with udev, so we didn't always see LUNs
3) We weren't showing the 0'th LUN, although that can be a valid LUN

*not* virStorageReportError() if the fork()/exec() process it spawned returned a
!= 0 exit code.  Rather, it returns the exitcode in this case, and it is up to
the higher level to determine whether this is a fatal error or not.  The use
case for this change is in the iSCSI stuff; older versions of iscsiadm tools
would return a failure when getting the session number, despite the command
succeeding.
