[libvirt] [PATCH] interface: fix udev backend use after free
by Doug Goldstein
udevIfaceListAllInterface() used the udev_device after it had its ref
count decremented which results in a use after free issue.

[libvirt] [PATCH 0/5] Clean up after recent Coverity scan
by John Ferlan
This is the last round of cleanup with a few Coverity errors from the
tests trees and a couple that just showed up in my recent scans within
security and virsh. The commandtest still has Valgrind errors, but errors
are not new to this change.
After this round of Coverity changes, the only remaining Coverity warnings
reported are within the gnulib tree. A few have been there all along within
vasnprintf.c, while others are new with the recent gnulib update (regexec.c,
regex_internal.c, and regcomp.c).
Once these are submitted I will have a baseline from which I can make
periodic comparisons. Since Coverity will sometimes "find" issues unrelated
to recent changes, using git bisect to point the fickle finger of fate at
a recent submission may not be possible.
John Ferlan (5):
drivermodule: Ignore coverity warning about leaked_storage
commandtest: Resolve some coverity resource leaks
vircommand: Remove unnecessary sa_assert
virsh: Resolve possible NULL dereference
security: Remove unnecessary checks for mgr == NULL

[libvirt] [PATCH 0/2] Restore DAC labels
by Michal Privoznik
If libvirt is doing labeling on a domain startup, the original
owner of files is not remembered. So later, when the domain is
shutting down and re-labelling is done, we have no other option,
just to fall back to 0:0. These patches are solving this issue
for DAC driver. I am sending them just to know if the path I wen
through is right so I don't bother with selinux if it is not.

conf: Add oldlabel field to virSecurityDeviceLabelDef

[libvirt] libvirt compilation error, libvirt.so: undefined reference to `xmlParseFile'
by nasb＠ruedesrancy.org
Hi,
I'm currently trying to compile libvirt 1.0.2 on my custom
x86_64/uClibc environnement. Configuration goes well (./configure
--prefix=/usr --without-pyton), but during make I get the following
error message :
CCLD libvirtd
/lslbuild/svn/trunk/packages/virtualization/libvirt/libvirt-1.0.2/src/.libs/libvirt.so:
undefined reference to `xmlParseFile'
collect2: error: ld returned 1 exit status
Looks like a -lxml2 flag missing, but configure found the correct flags
according to the Makefile which contains :
LIBXML_CFLAGS = -I/usr/include/libxml2
LIBXML_LIBS = -lxml2
Does anyone have an idea on what's going wrong? What other informations
should I provide?
Thanks,

[libvirt] Plan for the next release
by Daniel Veillard
February is short, but we are already at more then 180 commits
since 1.0.2 release, and well we ought to fix the python bindings
problems of 1.0.2 in an official release, so I think this makes
sense to push a new release at the end of the month.
I suggest to enter freeze in a week, targetting a 1.0.3 release
on the 28th or March 1st,
Daniel

Could anyone give me some suggestions? Thanks in advance.

[libvirt] [PATCH] Add support for <option> tag in network config
by Pieter Hollants
This patch adds support for a new <option>-Tag in the <dhcp> block of network configs,
based on a subset of the fifth proposal by Laine Stump in the mailing list discussion at
https://www.redhat.com/archives/libvir-list/2012-November/msg01054.html. Any such defined
option will result in a dhcp-option=<number>,"<value>" statement in the generated dnsmasq
configuration file.
Currently, DHCP options can be specified by number only and there is no whitelisting or
blacklisting of option numbers, which should probably be added.

[libvirt] [PATCH] conf: Generate agent socket path if missing
by Michal Privoznik
It's not desired to force users imagine path for a socket they
are not even supposed to connect to. On the other hand, we
already have a release where the qemu agent socket path is
exposed to XML, so we cannot silently drop it from there.
The new path is generated in form:
$LOCALSTATEDIR/lib/libvirt/qemu/$domain.agent
---
This makes the qemu agent to be generated at domain startup phase.
So until that, we generate XML without any path, e.g.:
<channel type='unix'>
<source mode='connect'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>
<address type='virtio-serial' controller='0' bus='0' port='1'/>
</channel>
The other possibility is to generate path during XML parse phase, however this
expose something we are lacking for years - callbacks to fill in default values
for not configured ones. The aim so to make libvirt accept this snippet as
valid qemu agent config:
<channel type='unix'>
<target type='virtio' name='org.qemu.guest_agent.0'/>
</channel>
