[libvirt] [PATCH] cgroup: refactor macros usage
by Roman Bogorodskiy
util/vircgroup.c uses a lot of macros to detect if cgroup is supported
by the system or not. These macros are pretty smart and allow to keep
code compact, however the downside of that is that it's getting harder
to navigate through the cgroup code.
So re-organise macros in a more simple fashion, i.e. just explicitly
provide functional and stub implementation for every public function.

[libvirt] [PATCHv2] build: fix configure detection of if_bridge.h on RHEL 6, try 2
by Eric Blake
This is a second attempt at fixing the problem first attempted
in commit 2df8d99; basically undoing the fact that it was
reverted in commit 43cee32f, plus fixing one more issue: the
code in configure.ac has to EXACTLY match virnetdevbridge.c
with regards to declaring in6 types before using if_bridge.h.
The rest of this commit message borrows from the original:
A fresh checkout on a RHEL 6 machine with these packages:
kernel-headers-2.6.32-405.el6.x86_64
glibc-2.12-1.128.el6.x86_64
failed to configure with this message:
checking for linux/if_bridge.h... no
configure: error: You must install kernel-headers in order to compile libvirt with QEMU or LXC support
Digging in config.log, we see that the problem is identical to
what we fixed earlier in commit d12c2811:
configure:98831: checking for linux/if_bridge.h
configure:98853: gcc -std=gnu99 -c -g -O2 conftest.c >&5
In file included from /usr/include/linux/if_bridge.h:17,
from conftest.c:559:
/usr/include/linux/in6.h:31: error: redefinition of 'struct in6_addr'
/usr/include/linux/in6.h:48: error: redefinition of 'struct sockaddr_in6'
/usr/include/linux/in6.h:56: error: redefinition of 'struct ipv6_mreq'
configure:98860: $? = 1
I had not hit it earlier because I was using incremental builds,
where config.cache had shielded me from the kernel-headers breakage.
* configure.ac (if_bridge.h): Avoid conflicting type definitions.
Signed-off-by: Eric Blake <eblake(a)redhat.com>

Although this fixes a build-breaker, this time I'm awaiting review
since my first attempt caused grief on Fedora.

[libvirt] Patch for BUG ID 994657
by Schmaus, John M. (John)
Hi All,
Here is the change I made to address the SIGSEGV we were seeing in libvirtd when attempting to create a new VM via virt-install:
- We call virDomainDefFree after xenDaemonCreateXML returns to xenUnifiedDomainCreateXML.
- xenUnifiedDomainCreateXML passes def to virGetDomain after XenDaemonCreateXML returns and before it calls virGetDomain.
- xenUnifiedDomainCreateXML calls virDomainDefFree(def) when it's done with def, so no need to free inside xenUnifiedDomainCreateXML.

I had not hit it earlier because I was using incremental builds,
where config.cache had shielded me from the kernel-headers breakage.

[libvirt] [PATCH] virthread: include config.h in the header file
by Paul Moore
The virthread.h header file includes platform specific header files
that help define the thread implementation, see code snippet below.
# ifdef WIN32
# include "virthreadwin32.h"
# elif defined HAVE_PTHREAD_MUTEXATTR_INIT
# include "virthreadpthread.h"
# else
# error "Either pthreads or Win32 threads are required"
# endif
Unfortunately, virthread.h does not include config.h so every source
file which includes virthread.h must also include config.h, regardless
of if the source file directly needs definitions in config.h. This
patch adds config.h to virthread.h in an effort to help simplify
things.
