[libvirt] [PATCH 2/4] lxc: ignore ECHILD errors during vm cleanup
by Dave Leskovec
This patch ignores ECHILD from waitpid(). This can happen if libvirtd was
restarted and the container processes are no longer the children of libvirtd.

[libvirt] [PATCH 1/4] lxc: validate tty pid before kill()
by Dave Leskovec
This patch adds a check of the tty forwarding process pid before kill()'ing it
when destroying a domain. If the pid value stored in the the vm structure is
invalid, sending a SIGKILL may be very bad if the value in question is something
like -1 (which just happens to be it's initial value).

[libvirt] [PATCH 0/4] lxc: cope with libvirtd restart
by Dave Leskovec
This set of patches fixes a few items that occur as a result of a restart of
libvirtd when containers are running. While this may not be a common situation,
the consequences of some of these (particularly losing the tty forwarding
process pid and later trying to kill it) can be quite severe.

[libvirt] PATCH: Fix python binding for listing storage pools/volumes
by Daniel P. Berrange
The python binding for the APIs to list storage pools and volumes has a
hand written C layer, but an auto-generated python layer. The latter was
auto-generating incorrectly, so this patch overrides its API contract
making the generator work correctly.
Dan.

[libvirt] PATCH: Convert lots of code to new memory APIs
by Daniel P. Berrange
This patch converts a large amount of the XML parsing/generating code in
the Xen and QEMU drivers over to using the new memory APIs, so we can get
OOM checking of it. In the process I've discovered and fixed a number of
double-free's, and leaks

[libvirt] PATCH: Convert buf.c to use memory alloc wrappers
by Daniel P. Berrange
This patch coverts the virBuffer code over to using our internal memory
allocation wrappers. It then fixes a bug in xend_internal.c where it
was failing to check for allocation failure, although this was technically
completely harmless, since the virBuffer routines already protected
against this specific scenario.

[libvirt] PATCH [0/2]: Deprecate conn, dom, net virterror fields
by Richard W.M. Jones
This is a pair of patches which deprecate the conn, dom and net fields
in the virterror structure.
Programs which use these fields will get a warning (if compiled under
gcc anyway):
foo.c:123: warning: 'dom' is deprecated (declared at /usr/include/libvirt/virterror.h:81)
The fields themselves are still present and still set, so the ABI
isn't changed.
Now the patch is quite a lot more involved than you might think for
such a simple change. Part of the problem is that we want to allow
libvirt itself to modify these fields without generating a warning.
Therefore the first part of the patch has to refactor all code within
libvirt which includes "libvirt.h" or "virterror.h" (the public
headers) so that instead this code just includes "internal.h".
"internal.h" already includes the public headers. This allows
"internal.h" to undefine the deprecation macro.
Of course nothing is quite so simple. We have two "internal.h" files,
so I renamed the one in the qemud directory to "qemud.h".
I also added something in the HACKING file, stating how *.c files
within libvirt should include header files.
The second part of the patch actually adds the deprecation to the
fields in virterror, and hence is small and simple.
Rich.
